Description

Technical Field

[0001] The utility model relates to the technical field of dust removal for pulverizers, in particular to a high-efficiency pulse dust remover for pulverizers. Background Art

[0002] Hammer mill is the most widely used type of mill at present. It has high electrical output and good versatility. Some hammers are connected to the rotor. When metal foreign matter enters the mill, it only breaks the screen and no major accident occurs. Various materials can be crushed by hammer mill. At the same time, in order to improve the use effect, a pulse dust collector will be installed on the hammer mill.

[0003] For example, a hammer mill with publication number CN201613153U includes a pulverizer and a cyclone separator. The structure of the utility model can improve the efficiency of pulverization and prevent clogging;

[0004] However, when the hammer mill is in use, since there is no structure in the middle box to actively clean the surface of the bags, the compressed air sprayed into the bags through the nozzles above the bags will reduce the amount of compressed air on the bag surface. Even when the compressed air pulse volume is insufficient, the impact force on the bags will be reduced, and the dust firmly attached to the surface cannot be washed away, thereby reducing the subsequent dust reduction effect of the bags and directly affecting the crushing efficiency. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a highly efficient pulse dust collector for a grinder, which solves the problem that in the existing hammer type grinder, there is no structure in the middle box body for actively cleaning the surface of the bag. In this way, after the compressed air is sprayed into the bag through the nozzle above the bag, the compressed air received by the bag surface will be reduced. Even when the compressed air pulse volume is insufficient, the impact force received by the bag will be reduced, and the dust firmly attached to the surface cannot be washed away.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: an efficient pulverizer pulse dust collector, comprising a base plate and a first support, a first support is fixedly connected to the middle of the upper part of the base plate, a dust collector body is fixedly connected to the upper and inner part of the first support, a first cross plate and a pair of second cross plates are respectively fixedly connected to the upper and lower parts of the dust collector body, and a screw is rotatably connected between the first cross plate and the second cross plate, a cleaning plate is threadedly connected to the upper outer wall of the screw, a cleaning brush is fixedly connected to the inner wall of the through hole of the cleaning plate, a dust removal mechanism is installed on the upper part of the dust collector body, a second support is fixedly connected to the upper left side of the base plate, and a pulverizer body is fixedly connected to the middle of the second support, a feed hopper is fixedly connected to the upper part of the pulverizer body, and a connecting mechanism is installed on the upper right side of the base plate.

[0007] Preferably, the dust removal mechanism includes a plurality of cloth bags fixed to the inside of the first cross plate, and the outer walls of the cloth bags are in contact with the inner wall of the cleaning brush, and the upper ends of the dust collector body are internally connected with cross bars through bearings for rotation, one end of the cross bar is connected to a motor fixed to the outer wall of the dust collector body, and the other end of the cross bar is fixed to a first bevel gear, and the lower part of the first bevel gear is meshedly connected with a second bevel gear fixed to the screw.

[0008] Preferably, a fan and a first pipeline are fixedly connected to the upper and lower parts of the dust collector body respectively, and the air intake pipe of the fan is connected to the interior of the dust collector body.

[0009] Preferably, a box body is fixedly connected between the pulverizer body and the bottom plate, and a second pipe and a filter screen are fixedly connected to the lower left side and the inner right side of the box body respectively.

[0010] Preferably, a sixth pipe is fixedly connected to the inside of the right side of the second support, and both ends of the sixth pipe are respectively connected to the box body and the dust collector body.

[0011] Preferably, the connecting mechanism includes an air storage tank installed on the right side of the upper surface of the base plate, the upper joint of the air storage tank is connected to the interior of the dust collector body through a third pipe, and a steam-water separator and an air compressor connected to the base plate are provided on the right side of the air storage tank, and the left and right sides of the steam-water separator are respectively connected to a fourth pipe and a fifth pipe, and the other ends of the fourth pipe and the fifth pipe are respectively connected to the air storage tank and the air compressor.

[0012] Beneficial Effects

[0013] The utility model provides a high-efficiency pulse dust collector for a pulverizer, which has the following beneficial effects:

[0014] The material can be discharged into the pulverizer body through the feed hopper, and the material is pulverized by the pulverizer body. At the same time, negative pressure is generated in the dust collector body through the fan. In this way, the dust during the pulverization can be sucked in with the sixth pipe and the filter screen, and the dust is blocked by the cloth bag in the dust collector body. The clean gas is then discharged through the air outlet pipe of the fan to achieve dust removal. When it is necessary to remove the dust from the cloth bag in the dust collector body, the air compressor can be used in conjunction with the steam-water separator, the fifth pipe and the fourth pipe to discharge the compressed air into the air tank. When the compressed air in the air tank is full, the valve on the air tank can be opened to discharge the compressed air in the air tank into the dust collector body through the third pipe, and the cloth bag is pulsed to further clean the dust on the cloth bag, thereby ensuring The compressed air pulse volume is stable and the impact force on the bag remains unchanged, thereby improving the subsequent dust suppression effect of the bag, and the dust attached to the screw is also processed when the bag is pulsed. At the same time, the first pipe is open, so that the blown dust can be discharged from the first pipe, and then the output shaft of the motor drives the first bevel gear to rotate through the cross bar, and the first bevel gear drives the screw to rotate through the second bevel gear. In this way, the screws rotating synchronously on both sides can drive the cleaning plate to move, and the cleaning plate drives the cleaning brush to move, and the dust on the surface of the bag is cleaned twice by the cleaning brush. When the bag is cleaned, the negative pressure air volume generated by the fan will pass through the screen of the crusher body in large quantities and quickly, taking away the material, thereby improving the crushing efficiency.
