Description

Technical Field

[0001] The invention relates to the technical field of dust recovery, and in particular to an explosion-proof dust removal device with high efficiency dust collection and recovery. Background Art

[0002] Explosion-proof dust collectors are used to address the risk of explosions that may occur when handling combustible dust in industrial environments.

[0003] On the one hand, dust explosions can be prevented. When combustible dust (such as metal dust) is suspended in the air, it may cause an explosion when it encounters an ignition source (such as sparks, static electricity). Explosion-proof dust collectors can effectively prevent this risk through special design and material selection; on the other hand, they can ensure the safety of the working environment and protect workers: workers working in flammable and explosive dust environments face extremely high safety risks. Explosion-proof dust collectors ensure the safety of workers by reducing dust concentration and preventing explosions; in addition, they can improve production efficiency and ensure continuous production: by effectively controlling dust and preventing explosions, explosion-proof dust collectors allow factories to operate in an uninterrupted and safe environment, improving production efficiency; finally, they can reduce environmental pollution and meet environmental protection requirements: dust not only poses a threat to safety, but also pollutes the environment. Explosion-proof dust collectors reduce dust emissions through efficient dust collection and recovery, meeting environmental protection requirements.

[0004] For example, Chinese patent publication number CN115569887A discloses an environmentally friendly dust centralized recovery device; The utility model comprises a recycling bin, wherein a debris collecting structure capable of cleaning up debris on the ground is installed at the front end of the recycling bin, a movable structure capable of driving the recycling bin to move is arranged at the bottom of the recycling bin, a dust suction structure capable of sucking up residual waste scraps of bamboo and wood products in the air is arranged at the upper end of the recycling bin, a water storage tank is fixedly installed at the top of the recycling bin, a water injection port is connected to the top of the water storage tank, a spray port is connected to the outer wall of the water storage tank, an electric telescopic rod is connected to the front end of the water storage tank, a water spray pipe and a bamboo tube A are arranged above the electric telescopic rod, a water spray structure is installed at one end of the water spray pipe, a movable drawer is movably connected inside the recycling bin, waste scraps and debris on the ground can be cleaned up by the arrangement of the debris collecting structure, and the recycling bin can be conveniently moved by the arrangement of the movable structure.

[0005] However, the above device still has some shortcomings in actual use: 1. The above device can clean up the waste and debris on the ground through the debris collection structure. However, it lacks self-cleaning after cleaning, which will cause dust and stains to stick to its cleaning brush during the subsequent cleaning process, causing secondary pollution to the ground.

[0006] 2. Although the above device can clean up the waste and debris on the ground, the recycled waste and debris cannot be separated, which will cause the recyclable part to be wasted, or need to be separated by an external separation device, which is more time-consuming and labor-intensive.

[0007] Therefore, based on the above-stated viewpoints, it is of great significance to improve and perfect the environmentally friendly dust centralized recovery device. Improving its lack of self-cleaning problem can prevent secondary pollution of the cleaned ground, and further improve the utilization rate of the recycled debris, which is more environmentally friendly.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-Figure 10 Embodiments of the present invention are described in detail.

[0035] The embodiment of the present application discloses an explosion-proof and efficient dust collection and recovery dust removal device, which explains that the present invention is mainly used in the process of dust recovery, and can avoid the problem of cleaning the cleaning device in terms of technical effect; further, the present invention can also solve the problem of not being able to process and recycle the collected dust, resulting in waste of resources and pollution to the environment.

[0036] Embodiment 1: Reference Figure 1 , Figure 2 and Figure 3 As shown, it includes a bracket 1, on which a collecting pipe 10 is arranged. The present invention mainly collects and processes dust in the air and recyclable solid waste in a processing environment. The dust will enter the collecting pipe 10 through a dust collection pump, and then be filtered from the collecting pipe 10 and return to the processing environment to achieve circulation, thereby avoiding the increased possibility of danger caused by the increase in dust content in the air in the processing environment, and can recycle solid waste, reduce waste emissions, and be more environmentally friendly.

[0037] An installation ring 11 is provided inside the collecting tube 10 so as to slide along the height direction of the bracket 1, a filter screen 12 is provided inside the installation ring 11 so as to slide along the length direction of the collecting tube 10, a square tube 13 is provided outside the collecting tube 10, and a processing box 14 connected with the collecting tube 10 and the square tube 13 is provided below the collecting tube 10. Dust is filtered through the filter screen 12 in the collecting tube 10, and then the filter screen 12 enters the processing box 14 through the square tube 13. Dust on the filter screen 12 is knocked off inside the processing box 14 to facilitate subsequent filtering and recycling processing, and then the filter screen 12 returns to the collecting tube 10 to continue filtering.

[0038] A separation box 15 and a filter box 16 are also provided on the bracket 1. A connecting pipe 17 penetrating the separation box 15 and the filter box 16 is provided at the upper ends of the separation box 15 and the filter box 16. The dust collected in the processing box 14 will enter the separation box 15 to perform preliminary screening on larger solid particles and dust in the air. Here, the main purpose is to collect recyclables in the air that are heavier than dust.

[0039] A through slot 80 is formed on one side of the mounting ring 11 close to the processing box 14 , and a folding baffle 81 is installed inside the filter screen 12 and the mounting ring 11 .

[0040] Since the filter 12 will slide left and right in the mounting ring 11, dust that falls during the sliding of the filter 12 may accumulate on the mounting ring 11. The function of the through groove 80 is that dust will fall into the processing box 14 through the through groove 80 during the sliding of the filter 12, and the function of the folding baffle 81 is to prevent the collection tube 10 on the other side of the mounting ring 11 from being connected to the square tube 13, causing the dust to return to the connecting tube 17 again, thereby affecting the dust collection effect.

[0041] Reference Figure 3 , Figure 4 and Figure 5 As shown, the dust on the filter 12 is driven to fall into the processing box 14; specifically, a driving plate 20 is symmetrically installed inside the square tube 13 along the width direction of the bracket 1, and the bottom of the driving plate 20 extends to the bottom of the processing box 14, and a mounting shaft 21 corresponding to the driving plate 20 is symmetrically arranged on the outside of the filter 12, and the mounting shaft 21 passes through the mounting ring 11 and is slidably connected to the driving plate 20, and the mounting ring 11 is provided with a mounting groove 22 for the mounting shaft 21 to slide, and the driving plate 20 is provided with a bending groove 23 for the mounting shaft 21 to slide.

[0042] When the driving plate 20 is driven to descend in the square tube 13 and enter the interior of the processing box 14, the mounting shafts 21 on both sides of the filter 12 will synchronously slide in the bending grooves 23, and at the same time, driven by the bending grooves 23, they will be driven to slide left and right in the mounting grooves 22. In this way, the filter 12 on the driving plate 20 can be shaken during the descent process, so that the dust on the filter 12 can fall into the interior of the processing box 14.

[0043] Reference Figure 6 and Figure 7 As shown, it is a schematic diagram of the structure for lifting the driving plate 20; specifically, a lifting groove is opened on the opposite side of the two driving plates 20 along its length direction, and a lifting screw 30 is rotatably installed inside the lifting groove, and a connecting block 31 is symmetrically arranged on the mounting ring 11, and the connecting block 31 is threadedly connected to the lifting screw 30.

[0044] It avoids the increased possibility of danger caused by increased dust content in the air in the processing environment, and can recycle solid waste, which is more environmentally friendly.

[0045] Reference Figure 2 , Figure 6 and Figure 7 As shown, it is a schematic diagram of the structure for further cleaning the filter 12; specifically, a cleaning member 4 for cleaning the filter 12 is arranged inside the processing box 14. The filter 12 shakes during entering the processing box 14, which can drive the dust to fall off. However, some dust may adhere to the filter 12, and it cannot be driven to fall off by simple shaking. The remaining dust adhered to the filter 12 is processed by the cleaning member 4. The cleaning member 4 includes a cleaning shaft 40 symmetrically arranged inside the processing box 14 along the length direction of the support frame. The cleaning shaft 40 is rotatably arranged along the width direction of the processing box 14. A plurality of cleaning brushes 41 are arranged on the cleaning shaft 40 along its axis, and the two cleaning shafts 40 are connected by a belt drive.

[0046] When the filter 12 enters the processing box 14 , the two cleaning shafts 40 will rotate relative to each other. At this time, the cleaning brushes 41 on the cleaning shafts 40 will contact the filter 12 to clean the dust on the filter 12 .

[0047] The brush head of the cleaning brush 41 is relatively soft to adapt to the left and right shaking of the filter screen 12 during the descending process, thereby preventing the cleaning brush 41 from causing damage to the filter screen 12 .

[0048] Reference Figure 6 and Figure 7 As shown, it is a schematic diagram of the structure for driving the cleaning brush 41 to rotate to clean the filter 12; specifically, a driving member 5 for driving the cleaning brush 41 is arranged inside the driving plate 20 and the processing box 14, and the driving member 5 includes an abutment shaft 50, and the abutment shaft 50 is rotatably arranged in the lifting groove of one of the driving plates 20, and one end of one of the cleaning shafts 40 is provided with a rotating roller 51 through a volute spring, and a driving rope 52 is arranged on the connecting block 31 corresponding to the abutment shaft 50, and the end of the driving rope 52 away from the connecting block 31 is wound around the rotating roller 51, and the driving rope 52 abuts against the abutment shaft 50.

[0049] When the connecting block 31 is in the process of descending with the driving plate 20, the connecting block 31 will pull the driving rope 52. During this process, due to the limitation of the abutment shaft 50, the rotating roller 51 will rotate under the pulling force of the driving rope 52, driving the rotating shaft 91 to rotate, and then driving the cleaning brush 41 to rotate. When the process of cleaning the filter 12 is completed, the connecting block 31 rises. At this time, the rotating roller 51 rotates in the opposite direction under the action of the volute spring, and the driving rope 52 is wound around the rotating roller 51 again.

[0050] Reference Figure 3As shown, it is a schematic diagram of the structure for preliminary screening of recyclables and dust in the air; specifically, the separation box 15 is set to be cylindrical at the upper end and conical at the lower end, and an air pump 18 is arranged between the separation box 15 and the processing box 14. The input end of the air pump 18 is connected to the processing box 14, and the output end of the air pump 18 is connected to the inside of the separation box 15. The output end of the air pump 18 is offset from the axis of the separation box 15.

[0051] The dust mixture in the processing box 14 will enter the separation box 15 through the air pump 18. Since the output end of the air pump 18 is eccentrically designed with the processing box 14, the dust and recyclable gas output by the air pump 18 will form a rotational motion in the processing box 14, forming a spiral airflow path. In this process, the larger particles of recyclables can be pushed to the inner wall of the processing box 14 through centrifugal force, so that they move downward along the inner wall of the processing box 14 and fall from the bottom of the separation box 15 for collection. In the separation process, the lighter dust and some lighter recyclables are subject to less centrifugal force, and will form an upward vortex in the central area of ​​the processing box 14, and finally be discharged through the top connecting pipe 17 into the filter box 16 for further filtration and separation.

[0052] Reference Figure 8 and Fig. 9 As shown, it is a schematic diagram of a structure for preventing some recyclables from adhering to the inner wall of the separation box 15; specifically, a scraper 6 is provided inside the separation box 15 to prevent the recyclables from adhering to the inner wall of the separation box 15 and affecting the separation effect of the dust mixture, and further prevent the recyclables from remaining and accumulating in the separation box 15, causing the clogging of the separation box 15. The scraper 6 includes an annular plate 60, which is rotatably arranged inside the separation box 15, and a scraper plate 61 is symmetrically arranged on the annular plate 60. A connecting ring 62 is also provided inside the separation box 15 and is sleeved on the outer side of the connecting pipe 17. The connecting ring 62 is connected to the annular plate 60, and a plurality of driving blades 63 are equidistantly installed on the connecting ring 62 along the axis of the separation box 15.

[0053] Since the output end of the air pump 18 is eccentrically arranged with respect to the separation box 15, when the air pump 18 delivers the gas mixed with dust and recyclables into the separation box 15, the gas will push the driving blades 63 on the connecting ring 62 to drive the connecting ring 62 to rotate, and then drive the annular plate 60 to rotate. At this time, the scraper plate 61 on the annular plate 60 will rotate along the axis of the separation box 15. During this process, the scraper plate 61 always contacts the inner wall of the separation box 15, and scrapes off the recyclables adhering to the inner wall of the separation box 15.

[0054] Reference Fig.10As shown, the smaller recyclables in the separated dust are filtered; specifically, a plurality of filter plates 70 are equidistantly arranged inside the filter box 16 , and the filter plates 70 are connected by connecting plates 71 .

[0055] The separated lighter dust and recyclables will enter the filter box 16 through the connecting pipe 17, and the mixture will be blown toward the filter plate 70 through the connecting pipe 17. At this time, the lighter dust and smaller recyclable particles will be separated layer by layer in the filter box 16.

[0056] Reference Fig.10 As shown, it is a schematic diagram of the structure for outputting and collecting dust; specifically, a discharge hopper 72 connected to the interior of the filter box 16 is rotatably provided at the bottom, the discharge port of the discharge hopper 72 is eccentrically arranged, and a discharge pipe 73 connected to the interior of the discharge hopper 72 is provided at the bottom of the discharge hopper 72.

[0057] The lighter recyclables will remain on the filter plate 70, while smaller dust particles will pass through the filter plate 70 and fall through the discharge pipe 73 on the discharge hopper 72 for collection, thereby achieving the effect of collecting dust in the working environment.

[0058] Embodiment 2: On the basis of the first embodiment, in order to further improve the applicability of the device, a steering member 9 is also proposed, which is conducive to separately collecting the dust and recyclables after filtering inside the filter box 16, and the recyclables can be collected without removing the filter plate 70.

[0059] Reference Fig.10 As shown, it is a schematic diagram of the structure that drives the discharge hopper 72 to rotate; specifically, the steering member 9 includes a steering gear ring 90, which is sleeved on the outer side of the discharge hopper 72, and a rotating shaft 91 is rotatably arranged on the outer side of the filter box 16 along its height direction, and a steering gear 92 meshing with the steering gear ring 90 is arranged on the side of the rotating shaft 91 close to the steering gear ring 90, and a first bevel gear 93 is arranged on the other side of the rotating shaft 91, and a steering shaft that passes through the filter box 16 is arranged on the connecting plate 71, and the steering shaft is rotatably arranged on the filter box 16, and a second bevel gear 94 meshing with the first bevel gear 93 is installed on the end of the steering shaft located on the outer side of the filter box 16.

[0060] After the filtering work in the filter box 16 is completed, and the dust in the filter box 16 is filtered and collected, the connecting plate 71 is driven to rotate, and the filter plate 70 is driven to rotate in the filter box 16. At the same time, the second bevel gear 94 connected to the connecting plate 71 rotates to drive the first bevel gear 93 to rotate. The first bevel gear 93 rotates, driving the rotating shaft 91 to rotate, and then the steering gear 92 is rotated. The steering gear 92 rotates and drives the discharge hopper 72 to rotate, causing the outlet direction of the discharge hopper 72 to shift. At this time, the recyclables on the filter plate 70 will fall due to the rotation of the filter plate 70, and fall from the discharge hopper 72 to another place for collection.

[0061] During operation: In the first step, dust and recyclables in the working environment are collected into a collection pipe 10 by a dust collection pump, and the dust mixture collected by the dust collection pump is filtered by a filter screen 12.

[0062] Step 2: When a certain amount of dust accumulates on the filter 12 in the collection tube 10, the lifting screw 30 rotates. At this time, the connection block 31 threadedly connected on the lifting screw 30 will carry the filter 12 on the mounting ring 11 to move toward the processing box 14 below the collection tube 10. In the process of the mounting ring 11 moving downward, the mounting shafts 21 on both sides of the filter 12 will slide in the bending groove 23, and then drive it to slide left and right in the mounting groove 22 of the driving plate 20. Through the left and right shaking of the filter 12 on the mounting ring 11, a part of the dust is mixed and shaken into the processing box 14 for collection.

[0063] Step 3: During the descent of the mounting ring 11, the connecting block 31 on the mounting ring 11 will simultaneously descend. During this process, the driving rope 52 on the connecting block 31 will drive the rotating roller 51 to rotate, so that the rotating roller 51 rotates with the cleaning shaft 40. At this time, the cleaning brush 41 on the cleaning shaft 40 will further clean the dust mixture remaining on the filter screen 12.

[0064] Step 4: After the dust mixture on the filter 12 is collected in the processing box 14, it will enter the separation box 15 through the air pump 18. In the separation box 15, the heavier recyclable particles will fall from the bottom of the separation box 15 and be collected by centrifugal force through spiral separation, and the lighter dust and some lighter recyclable particles will be discharged from the connecting pipe 17 above the processing box 14.

[0065] Step 5: The lighter recyclable particles enter the filter box 16 through the connecting pipe 17, and the finer recyclables and dust are separated by the filter plate 70. The separated dust falls through the discharge hopper 72 for collection.

[0066] Step 6: After the dust is collected, the filter plate 70 is driven to rotate, and then the second bevel gear 94 is rotated, driving the first bevel gear 93 to rotate, and the first bevel gear 93 drives the steering gear 92 to rotate. The steering gear 92 drives the steering gear ring 90 to rotate with the discharge hopper 72, and the recyclable particles on the filter plate 70 fall through the discharge hopper 72 to another place for collection.

[0067] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

[0068] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution.
