Description

TECHNICAL FIELD

[0001] The utility model relates to the field of civilian explosive production technology, and particularly relates to a conveying belt cleaning device for civilian explosive production. BACKGROUND

[0002] The production process of civilian explosives needs to meet relevant electrical and explosion-proof requirements. During the production process of civilian explosives, damaged cartridges are inevitably encountered during the conveying process of the conveying belt, which causes the cartridges to contaminate the conveying belt and other cartridges. The main contaminants of the cartridges are slurry-like viscous substances. At the same time, there are many requirements for the number of personnel on site and the patrolling area during the production process of civilian explosives, making it difficult to handle the residual explosives on the conveying belt in a timely manner by manual labor.

[0003] Under the prior art, civilian explosive production enterprises often use large-scale water flushing to solve the problem of conveying belt contamination, but there are two shortcomings: on the one hand, a large amount of water resources is wasted, and a large amount of high-nitrogen wastewater is generated, which does not meet the requirements of modern environmental management; on the other hand, there is a lack of effective conveying belt water removal facilities, which easily causes the packaging box to be damp, affecting the quality of the product. SUMMARY

[0004] The utility model aims at providing a conveying belt cleaning device for civilian explosive production to solve the above-mentioned problems of the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] A conveying belt cleaning device for civilian explosive production is arranged below the conveying belt and includes a water tank with an open top and a pump device. A partition is arranged in the water tank to form a cleaning zone above the partition and a water circulation zone below the partition. A plurality of cleaning mechanisms are fixedly installed in the cleaning zone by a support. The cleaning mechanisms include a spraying mechanism and a scraper mechanism. The water circulation zone is provided with an inclined pipe layer plate to form a clean water zone above the inclined pipe layer plate and a sewage zone below the inclined pipe layer plate. The cleaning zone and the sewage zone are connected. The clean water zone is provided with a water tank water outlet connected to the water inlet of the pump device. The water outlet of the pump device is connected to the spraying mechanism.

[0007] Further, the spraying mechanism uses a nozzle, and the scraper mechanism includes a bearing base, a scraper rotatably connected to one end of the bearing base, a silica gel scraping strip fixedly connected to the other end of the scraper, and a nozzle mounting seat arranged on the bearing base. The nozzle mounting seat and the scraper are connected by a spring. The nozzle is arranged on the nozzle mounting seat between two adjacent scrapers.

[0008] Further, the width of the silica gel scraping strip is not less than the width of the conveying belt and can be closely combined with the lower surface of the conveying belt, and the contraction direction of the spring is opposite to the rotation direction of the conveying belt.

[0009] Further, the inclined pipe layer plate comprises a plurality of parallel and fixedly connected inclined pipes, and the cross-sectional area of the inclined pipe is much larger than the water outlet of the water tank.

[0010] Further, the sewage area is funnel-shaped as a whole, and the lower end is provided with a sewage outlet.

[0011] Further, the pump device adopts a pneumatic diaphragm pump or a liquid conveying pump with the same function.

[0012] According to the above technical scheme, the water circulation mode is adopted to effectively clean various water-soluble pollutants attached to the surface of the conveying belt, so that the waste of a large amount of water resources and the generation of a large amount of sewage are avoided; at the same time, the inclined pipe is used to enhance the sewage sedimentation effect and improve the cleanliness of the circulating water; the conveying belt in the production process of civil explosive products is effectively cleaned in a water-saving and environmentally friendly manner, and the problem that the packaging box is prone to damp in the cleaning process is avoided.

When the nozzle sprays water, the water flow can be uniformly sprayed on the lower surface of the conveying belt, and the water after spraying is collected to the cleaning area through the blocking effect of the silica gel scraping strip 8.

[0019] The water circulation area of the preferred embodiment is provided with an inclined pipe layer plate 11, a clean water area above the inclined pipe layer plate 11 and a sewage area below the inclined pipe layer plate are formed, the cleaning area and the sewage area are communicated, the sewage area is integrally funnel-shaped, and a sewage discharge port 12 is arranged at the lower end; the clean water area is provided with a water tank water outlet connected with the water inlet of the pump device 2, and the water outlet of the pump device 2 is connected with the spraying mechanism; the inclined pipe layer plate 5 comprises a plurality of parallel and fixedly connected inclined pipes, the cross-sectional area of the inclined pipe is much larger than the water tank water outlet, so that the water flow speed can be greatly slowed down, the suspended impurities in the sewage are precipitated, and the cleanliness of the circulating water is improved.

[0020] The specific operation and working process of the conveying belt cleaning device of the preferred embodiment are as follows:

[0021] a. Add water to the water tank 1 until the partition plate 3 is covered;

[0022] b.

After being pressurized by the pneumatic diaphragm pump, water is supplied to the nozzle 5.

[0026] f. Pressurized water is quickly and evenly sprayed onto the lower surface of the conveyor belt through nozzle 5.
