Description

Technical Field

[0001] This utility model belongs to the field of dust removal technology for belt conveyors (also known as belt machines), specifically relating to an auxiliary cleaning device for a return belt dust collection device of a belt conveyor. Background Technology

[0002] The current conveyor belt return belt dust collection device can meet the dry dust collection needs, but under certain working conditions, there may be coarser particles that cannot be captured and collected by the dust collection device. For example, if there are large micro-cracks or damage on the surface of the belt, coarser particles will be trapped, and an auxiliary cleaning device needs to be added for cleaning and collection. Summary of the Invention

[0003] The purpose of this invention is to provide an auxiliary cleaning device for improving the effect of the return belt dust collection device of a belt conveyor.

[0004] The auxiliary cleaning device for the return dust collection system of the belt conveyor includes a dust collection box, a cleaning brush, a support, a compression spring, an air knife, and a counterweight flap. The dust collection box is installed behind the belt conveyor's surface-adjusting reel. The cleaning brush is installed inside the dust collection box on the lower surface of the return belt. The air knife is located at the front end of the dust collection box, with its blade facing inward to blow dust into the dust collection box, creating an airflow that facilitates dust collection into the dust removal system. A hole is opened at the bottom of the dust collection box below the cleaning brush, and a counterweight flap is installed for periodic dust discharge. The cleaning brush is mounted on the support, and the two ends of the support are engaged with elastic adjustment bases by limiting bolts wrapped with compression springs, ensuring that the cleaning brush is in close contact with the return belt. When the brush wears down, the compression spring releases to compensate, allowing the cleaning brush to remain in close contact with the return belt.

[0005] The cleaning brushes are arranged in a direction perpendicular to the direction of the return conveyor belt.

[0006] The cleaning brush is a wire brush or a nylon brush.

[0007] The air knife is supplied with air by the system fan, and a regulating valve is installed on the connecting pipeline.

[0008] The counterweight flap consists of a flap, a rotating shaft, a bearing seat, a cantilever, and a counterweight. The rotating shaft is fixed to one end of the back of the flap, and both ends of the rotating shaft are movably mounted on the dust collection box via the bearing seats. A cantilever is fixedly installed on one side of the rotating shaft, and the counterweight is fixed or suspended on the cantilever. The cantilever and the flap are installed opposite to each other on both sides of the rotating shaft.

[0009] The auxiliary cleaning device for the return dust collection device of the belt conveyor designed in this utility model is used to clean and collect coarse particles when there are large micro-cracks or damage on the surface of the belt. It has the characteristics of simple structure, convenient maintenance and significant effect. Attached Figure Description

[0013] Example 1

[0014] The auxiliary cleaning device for the return dust collection system of the belt conveyor includes a dust collection box, a cleaning brush 7, a support 12, a compression spring 6, an air knife 9, and a counterweight flap. The dust collection box is installed behind the belt conveyor's surface-adhesive pulley. The cleaning brush 7 is installed inside the dust collection box on the lower surface of the return belt. The cleaning brush 7 is arranged perpendicular to the direction of movement of the return belt 11, and cleans the sticky material with strong adhesion through the relative motion generated by the belt movement. The air knife 9 is located at the front end of the dust collection box, with a blade... The dust collection box is blown inwards to create an airflow that facilitates dust collection into the dust removal system. A hole is opened at the bottom of the dust collection box below the cleaning brush 7, and a counterweight flap is installed for periodic dust removal. The cleaning brush is mounted on a bracket 12, with both ends of the bracket 12 secured to an elastic adjustment base 8 by limiting bolts 5 wrapped with compression springs 6, ensuring the cleaning brush 7 is in close contact with the return conveyor belt 11. When the brush wears down, the compression springs 6 release to compensate, maintaining the cleaning brush 7 in close contact with the return conveyor belt 11. The cleaning brush is a wire brush. The air knife 9 is supplied with air by the system fan, and a regulating valve 10 is installed on the connecting pipe.

[0015] The counterweight-type flap consists of a flap 1, a rotating shaft, a bearing seat 2, a cantilever 3, and a counterweight 4. The rotating shaft is fixed to one end of the back of the flap 1, and both ends of the rotating shaft are movably mounted on the dust collection box via the bearing seat 2. The cantilever 3 is fixedly installed on one side of the rotating shaft, and the counterweight 4 is fixed or suspended on the cantilever 3. The cantilever 3 and the flap 1 are installed opposite each other on both sides of the rotating shaft, and the flap is sealed to the bottom of the dust collection box by lever action. When the dust accumulation on the flap reaches the trigger value of the flap, the flap rotates to discharge the accumulated dust. After unloading, the flap automatically resets under the action of the counterweight.
