Technical Field

[0001] The present application relates to the field of industrial dust removal equipment, and in particular to an explosion-proof, dust-proof and compacting integrated dust collector. Background Art

[0002] With the development of economy, industries such as laser processing, 3D printing, high vacuum, low oxygen, polishing processing, plastics, organic synthesis, powder metallurgy and food processing are also developing. The types and amount of dust are increasing rapidly, and the automation and continuity of the operation process have greatly increased the potential danger of dust. It is of great practical significance to prevent dust. Therefore, in the production process, it is necessary to strictly implement the national technical specifications and operating procedures, implement various safety regulations and systems, and avoid dust accidents.

[0003] For the purpose of explosion-proof safety and environmental protection, the production workshop of new energy batteries has strict requirements on the cleanliness of air dust, so dust collectors are usually installed in the workshop. Pulse dust collector is one of the common types of dust collectors. It is equipped with filter element, fan and pulse device. The operation of the fan makes the external air flow through the filter element and be discharged. The dust particles adhere to the filter element. The pulse device back-blows the filter element, and the dust on it falls to the bottom of the equipment so that it can be collected and processed, and the filter element can continue to be used effectively.

[0004] When the operator opens the bottom of the dust removal equipment to take out the collected dust, the uncertain air pressure and airflow factors in the workshop environment will affect the dust pile, which can easily cause the dust particles to float back into the air, causing secondary pollution and affecting the safety of the equipment. Summary of the invention

The loose dust is formed into a powder cake after being pressed. The powder cake is a larger solid block, and it is not easy to generate a large amount of dust floating when collected, which reduces the possibility of secondary pollution and improves operational safety.

[0009] Preferably, the cake pressing assembly includes a gate plate and a pressing piston block, both of which are slidably arranged relative to the processing chamber, the sliding direction of the gate plate is perpendicular to the sliding direction of the pressing piston block, the dust is located between the gate plate and the pressing piston block, the side wall of the pressing piston block is in contact with the inner wall of the processing chamber, and in the projection perpendicular to the gate plate surface, the contour of the inner wall of the processing chamber is located within the gate plate surface range, a discharge port is provided on the processing chamber and on the side of the gate plate away from the pressing piston block, and the cake pressing assembly also includes a driving source for controlling the independent movement of the gate plate and the pressing piston block respectively.

[0018] Preferably, a secondary filter cavity is further provided in the box body, and the secondary filter cavity is connected between the primary filter cavity and the air outlet pipe. A secondary filter element is detachably provided on the box body and in the secondary filter cavity.

[0019] By adopting the above technical solution, the filtering accuracy of the secondary filter element needs to be higher than that of the primary filter element. Whether the secondary filter element is set is determined according to actual processing requirements and other actual conditions. If filter cotton is not set, the airflow entering the secondary filter cavity directly reaches the outlet pipe after passing through the secondary filter cavity.

[0025] By adopting the above technical solution, after the impregnated cotton ring is set, when the powder cake is pushed and passes through the impregnated cotton ring, the edge of the powder cake contacts with the impregnated cotton ring and is soaked. Even if the dust here is hit, it is not easy to generate floating dust; because the size of the forming part is wider than the size of the thrust part, that is, the moisture on the impregnated cotton ring will not contact the pressing piston block, and the pressing piston block can remain dry for a long time.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-7 This application is described in further detail.

[0038] Embodiment 1:

[0039] The present application embodiment discloses an explosion-proof, dust-proof and compacting integrated dust collector, such as Figure 1 As shown, it includes a box body 1, on which an air inlet pipe 13 and an air outlet pipe 14 are arranged, and a filtering dust removal mechanism 2 and a pressing mechanism 4 are arranged inside the box body 1; the internal space of the box body 1 includes a primary filter chamber 11 and a secondary filter chamber 12. The filtering dust removal mechanism 2 includes a filter element and a fan 23, and when the fan 23 is running, an airflow is generated that passes through the air inlet pipe 13, the primary filter chamber 11, the secondary filter chamber 12 in sequence and finally leaves through the air outlet pipe 14; during this period, the filter element intercepts and filters the dust impurities floating in the airflow. The pressing mechanism 4 is used to press and process part of the dust impurities intercepted by the filtering dust removal mechanism 2.

[0040] like Figure 1As shown, the filter element includes a primary filter element 21 and a secondary filter element 22. The primary filter element 21 is a filter cartridge, which is installed in the primary filter cavity 11 of the housing 1. The secondary filter element 22 is a filter cotton, which is installed in the secondary filter cavity 12 of the housing 1. The filtering effect of the secondary filter element 22 is better than that of the primary filter element 21. The airflow passes through the filter cartridge in the primary filter cavity 11, and passes through the filter cotton in the secondary filter cavity 12; the filter cartridge and the filter cotton are detachably connected to the housing 1, respectively, and are used to filter the gas with different intensities. Whether the secondary filter element 22 is set or not is determined according to the actual processing requirements and other actual conditions. If the filter cotton is not set, the airflow entering the secondary filter cavity 12 directly reaches the outlet pipe 14 after passing through the secondary filter cavity 12. The flow direction of the airflow relative to the filter cartridge is from outside the cartridge to inside the cartridge. A pulse backblower is provided inside the filter cartridge, which is used to backblow the filter cartridge to remove dust, so that the dust intercepted on the filter cartridge falls from the filter cartridge. A dust hopper 15 is provided inside the box body 1 and at the bottom of the primary filter chamber 11. The dust falls into the dust hopper 15 after leaving the filter cartridge.

[0041] like Figure 1 and 2 As shown, the pressing mechanism 4 includes a processing bin 41 and a pressing cake assembly 42. The processing bin 41 is located in the housing 1 and is connected to the bottom of the dust hopper 15. A butterfly valve is provided between the processing bin 41 and the dust hopper 15. When the butterfly valve is opened, the dust accumulated in the dust hopper 15 will fall into the processing bin 41. The pressing cake assembly 42 is used to press and shape the dust in the processing bin 41. The space in the processing bin 41 is cylindrical, and its length direction is horizontal. The pressing cake assembly 42 includes a gate plate 422 and a pressing piston block 421. The gate plate 422 and the pressing piston block 421 are both slidably arranged relative to the processing bin 41. The sliding direction of the pressing piston block 421 is consistent with the length direction of the processing bin 41. The sliding direction of the gate plate 422 is perpendicular to the sliding direction of the pressing piston block 421. The dust is located between the gate plate 422 and the pressing piston block 421. The gate plate 422 is located in the middle of the processing chamber 41, and its sliding direction is vertical, and the plate surface is perpendicular to the length direction of the processing chamber 41. In the projection along the plate surface perpendicular to the gate plate 422, the inner wall contour of the processing chamber 41 is completely within the plate surface range of the gate plate 422, and the gate plate 422 divides the inner cavity space of the processing chamber 41 into two. The pressing piston block 421 and the dust collecting hopper 15 are located on the same side of the gate plate 422. The pressing piston block 421 moves toward the gate plate 422, and the pressing piston block 421, the inner wall of the processing chamber 41 and the gate plate 422 jointly squeeze the dust in the processing chamber 41. The cake pressing assembly 42 also includes a driving source 423 for controlling the independent movement of the gate plate 422 and the pressing piston block 421 respectively. The driving source 423 includes a lifting cylinder 4231 and a thrust electric cylinder 4232, both of which are fixedly connected to the box body 1. The piston rod of the lifting cylinder 4231 is connected to the top of the gate plate 422, and the piston rod of the thrust electric cylinder 4232 is fixedly connected to the side of the pressing piston block 421 away from the gate plate 422.

[0042] like Figure 1 and 2 As shown, a discharge port 413 is provided at the end of the processing bin 41, and the discharge port 413 is located on the side of the gate plate 422 away from the pressing piston block 421, and the opening direction of the discharge port 413 is bent and tilted downward; after the pressing piston block 421 squeezes the dust and maintains the pressure to shape it, the dust forms a powder cake, and then the gate plate 422 moves up, and the pressing piston block 421 moves toward the discharge port 413, and finally pushes the powder cake to the discharge port 413, and the powder cake falls naturally to achieve discharge. In order to reduce the mutual adhesion between the dust and the inner wall of the processing bin 41, the pressing piston block 421 and the gate plate 422, the pressing mechanism 4 also includes a powder spraying device 45, which is used to spray dry anti-sticking powder (the nozzle is located next to the butterfly valve) into the processing bin 41 before opening the butterfly valve at the bottom of the dust collecting hopper 15, which is used to balance the oily powder and sticky powder in the dust and reduce the stickiness of the dust particles. In this embodiment, the anti-sticking powder is sweet potato flour.

[0043] like Figure 1 and 3 As shown, the box body 1 is also provided with an explosion-proof mechanism 3, which includes a spark arrester 31, a cooling assembly 33 and an explosion relief device 32. The spark arrester 31 is located on the air intake pipe 13, and when it detects sparks in the air flow in the air intake pipe 13, it can extinguish them in time. The cooling assembly 33 includes a cooling bin 331, a mounting plate 332 and a plurality of cooling fins 333. The cooling bin 331 is arranged on the housing 1, and the cooling bin 331 is connected between the air pipe and the primary filter chamber 11; a plurality of cooling fins 333 are fixedly mounted on the mounting plate 332 and arranged in an array on the mounting plate 332, the mounting plate 332 is connected to the cooling bin 331, and the cooling fins 333 are located in the cooling bin 331. When the airflow flows through the cooling bin 331, it passes through the gaps between adjacent cooling fins 333; the outside of the mounting plate 332 is in contact with circulating cooling water (not shown in the cooling water system diagram), which is used to maintain the low temperature state of the cooling fins 333, thereby cooling the passing airflow and reducing the temperature of the airflow entering the housing 1, thereby improving safety. The explosion-proof mechanism 3 also includes an explosion relief device 32, which is installed on the top of the box body 1. Even if an explosion occurs inside the box body 1, the explosion relief device 32 can quickly relieve the pressure generated by the explosion at the top of the box body 1, thereby reducing the damage to the structure of the box body 1 caused by the impact of the explosion.

[0044] Embodiment 2:

[0045] like Figure 4 and 5As shown, the difference from Example 1 is that in this embodiment, the processing chamber 41 is divided into a thrust portion 411 and a molding portion 412 which are coaxially connected to each other, the bottom of the dust collecting hopper 15 is connected to the thrust portion 411, the molding portion 412 is located between the thrust portion 411 and the discharge port 413, the inner diameter of the molding portion 412 is larger than the inner diameter of the thrust portion 411, the gate plate 422 is located in the molding portion 412, and the side wall of the pressing piston block 421 is in contact with the inner wall of the thrust portion 411; when the dust is squeezed, the junction position of the thrust portion 411 and the molding portion 412 is the end point of the stroke of the pressing piston block 421, that is, the driving source 423 controls the pressing piston block 421 to move toward one side of the gate plate 422 to the junction of the thrust portion 411 and the molding portion 412, and the radial size of the powder cake formed thereby is consistent with the inner diameter of the molding portion 412.

[0046] like Figure 4 , 5 As shown in 6, an auxiliary groove 4211 is provided on the side of the pressing piston block 421 facing the dust, and an auxiliary push block 43 is slidably provided on the pressing piston block 421 and in the auxiliary groove 4211. The sliding direction of the auxiliary push block 43 is consistent with the sliding direction of the pressing piston block 421. The pressing mechanism 4 also includes a control component 44 for driving the auxiliary push block 43 to slide relative to the pressing piston block 421. The control component 44 includes a round-headed push block 441, a wedge-faced push block 442 and a return spring 443. The round-headed push block 441 is fixedly connected to the lower end of the gate plate 422, the wedge-faced push block 442 is fixedly connected to the upper side of the auxiliary push block 43, one end of the return spring 443 is connected to the auxiliary push block 43, and the other end is connected to the pressing piston block 421. In a natural state, the return spring 443 applies a thrust toward the bottom of the auxiliary groove 4211 to the auxiliary push block 43, so that the auxiliary push block 43 retracts into the auxiliary groove 4211. The side of the wedge-faced push block 442 facing the dust is located at the notch of the auxiliary groove 4211. When the pressing piston block 421 squeezes the dust, the auxiliary push block 43 contacts the dust.

[0047] like Figure 5 and 6 As shown, after the pressing and molding is completed, the dust forms a powder cake, and the driving source 423 causes the gate plate 422 to rise and the pressing piston block 421 to move, pushing the powder cake to move toward the discharge port 413; it stops moving when the round head push block 441 is directly above the wedge push block 442. At this time, the driving source 423 controls the gate plate 422 to move downward, so that the wedge surfaces of the round head push block 441 and the wedge push block 442 contact and produce extrusion. Under the action of the wedge surface pushing, the auxiliary push block 43 moves relative to the pressing piston block 421, and the auxiliary push block 43 pushes the powder cake to separate from the pressing piston block 421; this action is similar to the push rod during injection molding demolding, which is beneficial to reduce the difficulty of pushing due to the adhesion between the powder cake and the pressing piston block 421, and improve the smoothness of discharge.

[0048] like Figure 6 and 7 As shown, a soaking cotton ring 46 is coaxially fixedly connected on the inner wall of the forming part 412 and located on the side of the gate plate 422 away from the thrust part 411. The lower middle part of the soaking cotton ring 46 extends out of the processing chamber 41 through its own cotton strip and is immersed in water (not shown in the figure). Under the action of osmosis, the entire surface of the soaking cotton ring 46 is filled with water. Since the powder cake itself is a flat object, the edges and corners of its edges are prone to dust shedding when hit, that is, the collision that occurs during the falling process of the powder cake can cause a small amount of dust to float. After the soaking cotton ring 46 is set, the edge of the powder cake contacts the soaking cotton ring 46 and is soaked during the process of the powder cake being pushed and passing through the soaking cotton ring 46. Even if the dust here is hit, it is not easy to generate floating dust. Since the size of the forming part 412 is wider than the size of the thrust part 411, that is, the water on the soaking cotton ring 46 does not contact the pressing piston block 421, the pressing piston block 421 can remain dry for a long time.

[0049] The implementation principle of an explosion-proof, dust-proof and compacting integrated dust collector in the embodiment of the present application is:

[0050] When the pulse backblower is working, the fan 23 stops running, the butterfly valve under the dust hopper 15 opens, and the dust separated from the filter cartridge falls into the processing bin 41. When the dust in the processing bin 41 accumulates to a certain weight, the pressing mechanism 4 starts and presses the dust, and the formed powder cake is finally discharged in blocks and collected for processing, reducing secondary pollution during the collection process.

[0051] The layout of the parts of this equipment is relatively compact and can meet the characteristics of miniaturized design. The size range of the box 1 (length x width x height) is: 840x750x2800mm~1300x1200x2800mm, and the diameter range of the air inlet pipe 13 is 50-150mm; the power range of the adapted fan 23 is 0.75kW-11kW, and the dust removal capacity range is 150-1100 cubic meters / hour.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
