Hose Conveyor For Vertical Chemical Powder

Hose Conveyor For Vertical Chemical Powder uses a flexible hose as the conveying medium, driven internally by helical blades or wire springs. Materials are smoothly pushed within the completely sealed hose. Compared to rigid conveying equipment, it eliminates the need for complex intermediate supports or sealing structures, easily bypassing obstacles and adapting to confined spaces, achieving continuous horizontal and vertical conveying. Especially for chemical powders, the fully enclosed pipeline prevents dust leakage and external contamination, ensuring operator safety and meeting environmental and explosion-proof requirements. The flexible design allows for easy repositioning and relocation of products, enabling single-person operation.

What are the advantages of the Hose Conveyor for Vertical Chemical Powder?

The Hose Conveyor for Vertical Chemical Powder features a fully enclosed, flexible design, achieving dust-free, low-breakage, easy-to-clean, and flexible tubing installation. It also supports explosion-proof configurations, providing chemical companies with a safe and rapid vertical lifting solution.

Enclosed Conveying: Chemical powders are highly susceptible to dust and moisture. The hose structure ensures leak-free operation from inlet to outlet, eliminating the need for additional dust collection equipment.

Flexible Layout: The flexible hose allows for easy vertical or inclined combined conveying, saving plant space.

Low Breakage: The gentle spiral pushing method maintains the original particle shape of brittle or mixed powders.

Abrasion Resistance: The hose's durable, wear-resistant material allows for the addition of explosion-proof motors, adapting to the corrosiveness and safety requirements of various chemicals.

How does the Hose Conveyor for Vertical Chemical Powder work?

The core component of the Hose Conveyor for Vertical Chemical Powder is a helical spring or rigid helical blade installed inside the flexible hose. When the geared motor drives the helical blade to rotate, the thrust of the helical blade pushes the chemical powder from the inlet to the outlet. In the vertical conveying section, the high-speed rotation of the screw generates an upward axial thrust, while the friction between the material and the inner wall of the hose provides auxiliary support, preventing the material from sliding down. Finally, the powder or granules are carried by the screw until they reach the discharge port.

Hose Conveyor for Vertical Chemical Powder Structure

The structural design of the Hose Conveyor for Vertical Chemical Powder revolves around airtightness and flexible conveying. From the flexible hose, screw assembly, drive unit, to the feed inlet, vertical elbow, and support sealing components, each part is optimized for the dust-prone and adhesion-prone characteristics of chemical powders.

Flexible Hose: Typically made of wear-resistant and chemically corrosion-resistant rubber material with a smooth inner wall and a small bending radius.

Screw Assembly: Available in spring steel wire screw and integrated steel screw blades.

Drive Unit: Located at the discharge or feed end, equipped with a geared motor and frequency converter, allowing stepless adjustment of the conveying speed.

Feed Inlet: Can be designed as a hopper, flange, or quick-connect clamp, suitable for upstream equipment such as reactors and ton bag unloading stations.

Hose Conveyor for Vertical Chemical Powder Technical Parameters

Hose Conveyor for Vertical Chemical Powder Application Scenarios

From chemical raw material feeding and vertical lifting of lithium battery powder to closed-loop dye batching, the flexible and fully enclosed hose conveyor is suitable for various chemical powder applications, especially in space-constrained, explosion-proof, or rapidly changing material environments.

Chemical Raw Material Transfer: Vertically lifts powders such as titanium dioxide, calcium carbonate, and stearates from bags or ton bags to mixing tanks or buffer silos 3-8 meters high.

Pigment and Dye Batching: Provides closed-loop transport of ultrafine pigment powders, preventing cross-contamination and workshop dyeing, particularly suitable for production lines with multiple formulation changes.

Lithium Battery Positive and Negative Electrode Materials: Transports powders sensitive to moisture and metallic impurities such as lithium iron phosphate, graphite, and conductive carbon black. Custom-designed anti-static hoses and explosion-proof motors are included.

What is the maximum vertical height of the Hose Conveyor for Vertical Chemical Powder?

The vertical conveying capacity of the Hose Conveyor for Vertical Chemical Powder is not a fixed value but is significantly affected by the material characteristics. For chemical powders with good flowability, the vertical height will decrease significantly due to the low friction of the material itself, and it is generally recommended to control it within 3-5 meters. For materials with poor flowability and high internal friction, they will support each other during the conveying process and will not fall quickly, allowing for a vertical height of 6-8 meters. In practical engineering, if the material has a high coefficient of friction, it can be improved by increasing the screw speed, using a high-thrust steel blade screw, or adding a PTFE lining to the inner wall of the hose.

Hose Conveyor for Vertical Chemical Powder Customer Cases

We provide different conveying solutions for customers in different industries during the production process, ensuring that each conveyor can perfectly adapt to the customer's existing production line and guarantee the normal operation of the entire production line.

Titanium Dioxide Processing Plant: The plant needs to vertically lift bagged titanium dioxide (325 mesh, bulk density 0.6 t/m³) 4 meters from the ground to the mixing tank inlet. The original bucket elevator had problems with excessive dust and aging seals. After switching to a flexible hose conveyor, equipped with anti-static PU hoses and an explosion-proof motor, the vertical height reaches 4.2 meters, and the conveying capacity is 3.5 tons/hour.

A lithium battery material company: The customer needs to vertically convey lithium iron phosphate powder to a 5-meter-high screening machine. A flexible hose conveyor with a stainless steel spiral and PTFE lining was selected, with a vertical height of 5 meters and frequency conversion control to achieve a production capacity of 1.2 tons/hour.

A dye and color matching company: The customer, in a three-story workshop layout, needs to vertically lift different colored acidic dye powders from the first-floor hopper to the second-floor weighing module. A customized flexible hose conveyor with a vertical height of 4.5 meters, using a large-diameter spiral and an explosion-proof frequency conversion motor, has a conveying capacity of 0.8 tons/hour. The hose can be quickly disassembled, and compressed air is used for cleaning during color changes, reducing batch changeover time from 2 hours to 15 minutes.

FAQ

How do you prevent chemical powder from clogging in a vertical conveyor?

Variable frequency speed control of the screw speed prevents it from being too fast or too slow; an anti-bridging device is installed at the feed inlet to prevent bridging; the vertical height can be appropriately reduced for highly viscous powders.

Is the vertical hose conveyor suitable for hazardous or explosive powders?

Yes. It can be equipped with an explosion-proof motor, anti-static hose, grounding device, and explosion-proof junction box. The fully enclosed structure prevents dust leakage and avoids the formation of an explosive atmosphere.

What is the maintenance frequency for a chemical powder conveyor?

The minimum bending radius of the hose is generally 3-5 times the pipe diameter. For example, a 100mm diameter hose can be bent to a radius of 300-500mm, corresponding to a maximum bending angle of approximately 90°-180°. It is recommended to avoid prolonged extreme bending in actual use.
