Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of powder dust collectors, in particular to a coal powder dust collector. Background Art
[0002] Coal powder refers to coal with a particle size of less than 0.5 mm, and is the most commonly used additive in cast iron sand. In recent years, foreign countries have mixed coal powder with clay to supply the market as a commodity. Adding coal powder to wet sand for cast iron can prevent sand adhesion defects on the surface of the casting, improve the surface finish of the casting, reduce sand inclusion defects, and improve the collapse function of the sand. For wet ductile iron parts, it can also effectively prevent the formation of subcutaneous pores. A circular vortex burner can be used without preheating the air. After using the device to process the coal into coal powder, a coal powder dust collector is needed to collect the coal powder, and after collection, it is transported to the storage site for storage.
[0003] When coal is processed into coal powder by a grinding device, many large particles that do not meet the requirements, as well as sand and gravel and other debris will be mixed in the coal powder. The current coal powder dust collector does not have the function of filtering out these large particles or sand and gravel and other debris, so that these debris are stored and used together with the coal powder, resulting in a significant reduction in the quality of the coal powder. At the same time, when the current coal powder dust collector takes out the coal powder for centralized storage or use, a lot of residues will remain inside. These residues usually need to be cleaned manually with cleaning tools, which will result in a lot of labor consumption, thereby increasing labor costs. Utility Model Content

[0018] Through the above technical solution, the dust collection box is taken out by pulling the handle to open the box door.
[0019] Furthermore, through the above technical solution, a baffle is fixedly connected to the left part of the wire frame, and the pull rod penetrates through the inside of the card slot;
[0020] Through the above technical solution, the wire frame is limited by the fixing plate to prevent the wire frame from completely sinking into the filter box.

[0032] Referring to Figures 1-5 , an embodiment provided by the present invention: a pulverized coal dust collector, including a filter box 6, a filter mechanism 3 is arranged on the upper side inside the filter box 6, a pulverized coal tank 1 is arranged on the top of the filter box 6, and a cleaning mechanism 2 is arranged on the outer periphery of the upper part of the pulverized coal tank 1;
[0033] The filter mechanism 3 includes a pull rod 301, a clamping groove 302, a filter screen 303, a wire mesh frame 304, and a spring 305. Clamping grooves 302 are arranged on both the front and rear sides of the left part of the wire mesh frame 304. The wire mesh frame 304 is slidably connected to the upper inner side of the filter box 6. A filter screen 303 is arranged inside the wire mesh frame 304. Pull rods 301 are slidably connected to both the front and rear sides of the upper part of the filter box 6. Springs 305 are arranged on the outer periphery of the middle part of the pull rods 301. Pulverized coal slowly falls from the pulverized coal tank 1 into the dust collection box 7 inside the filter box 6. During the process of falling into the filter box 6, the pulverized coal is filtered by the filter screen 303, and the impurities mixed in the pulverized coal are filtered. When the filter screen 303 can no longer filter, pull the pull rod 301. After the pull rod 301 is pulled out of the clamping groove 302, the wire mesh frame 304 with the filter screen 303 is taken out. After taking out, the filter screen 303 is removed and a new filter screen 303 is replaced. Then, the wire mesh frame 304 with the new filter screen 303 is inserted into the filter box 6. After putting it in, the spring 305 generates an elastic force to push the pull rod 301 into the clamping groove 302 again. The wire mesh frame 304 is fixed by the cooperation of the pull rod 301 and the clamping groove 302.
[0034] The cleaning mechanism 2 includes a water distribution pipe 201, a pump water pipe 202, a water pump 203, a water suction pipe 204, and a high-pressure nozzle 205. The water distribution pipe 201 is fixedly connected to the outer periphery of the upper part of the pulverized coal tank 1. The front part of the water distribution pipe 201 is fixedly connected to the pump water pipe 202. The pump water pipe 202 is fixedly connected to the top of the water pump 203. The front part of the water pump 203 is fixedly connected to the water suction pipe 204. A plurality of uniformly distributed high-pressure nozzles 205 are arranged on the upper side inside the pulverized coal tank 1. The water pump 203 pumps water through the water suction pipe 204, and then the water pump 203 pumps the water to the water distribution pipe 201 through the pump water pipe 202. The high-pressure nozzles 205 spray the water in the pump water pipe 202 onto the inner wall of the pulverized coal tank 1. When the water is used to clean the pulverized coal tank 1, it flows into the filter box 6, and then the filter box 6 is cleaned. The high-pressure nozzles 205 penetrate through the outer periphery of the upper part of the pulverized coal tank 1 and are connected to the water distribution pipe 201. The top of the pulverized coal tank 1 is fixedly connected to a feed inlet 5. Pulverized coal is added into the pulverized coal tank 1 through the feed inlet 5.

The pull rod 301 penetrates through the inside of the card slot 302.
[0035] Working principle: When it is necessary to collect pulverized coal, first add the pulverized coal into the pulverized coal tank 1 through the feed inlet 5. The pulverized coal tank 1 is connected to the filter box 6. The pulverized coal slowly falls into the dust collection box 7 inside the filter box 6. During the process of falling into the filter box 6, the pulverized coal is filtered by the filter screen 303, and the impurities mixed in the pulverized coal are filtered. When the filter screen 303 can no longer filter, pull the pull rod 301. After the pull rod 301 is pulled out of the card slot 302, the wire mesh frame 304 with the filter screen 303 is taken out. After taking out, remove the filter screen 303 and replace it with a new filter screen 303. Then insert the wire mesh frame 304 with the new filter screen 303 into the filter box 6. After putting it in, the spring 305 generates elastic force to push the pull rod 301 into the card slot 302 again. The wire mesh frame 304 is fixed by the cooperation of the pull rod 301 and the card slot 302. After the pulverized coal is removed, start the water pump 203. The water pump 203 pumps water through the water suction pipe 204, and then the water pump 203 pumps the water to the water distribution pipe 201 through the pump water pipe 202. The high-pressure nozzles 205 spray the water in the pump water pipe 202 onto the inner wall of the pulverized coal tank 1. When the water is used to clean the pulverized coal tank 1, it flows into the filter box 6, and then the filter box 6 is cleaned. After cleaning, pull out the dust collection box 7 with sewage and pour out the sewage.
