Description

Technical Field

[0001] The present invention relates to the technical field of bag dust removal, and specifically relates to a bag - type dust removal device with a multi - stage dust removal effect. Background Technique

[0002] In a factory environment, especially in the processing of air with dust dispersion, in order to have a good environment and the physical health of workers, a dust removal device needs to be used. Among them, for dust removal, bag dust removal is the most suitable. In order to better remove dust from the air, it usually requires multi - stage treatment to better ensure the treatment of dust.

[0003] After the bag dust removal mechanism filters the dust in the air, the dust will adhere to the surface of the bag. In order to ensure the filtering effect of the bag dust removal mechanism, it is usually necessary to clean the dust on the surface of the bag. The existing cleaning technology usually uses the blowing and back - flushing technology to remove dust from the bag. However, when using the blowing and back - flushing cleaning technology to remove dust from the bag, there are certain limitations. If the air introduced into the bag has a low temperature or a high water content, it will cause the phenomenon of back - moisture on the surface of the bag, resulting in dust adhering to the bag. The dust on the surface of the bag cannot be blown off by simple blowing and back - flushing, which affects the filtering effect of the entire bag. Summary of the Invention

[0004] The purpose of the present invention is to provide a bag - type dust removal device with a multi - stage dust removal effect, so as to solve the problems raised in the above - mentioned background technique.

[0005] To achieve the above - mentioned purpose, the present invention provides the following technical solution: A bag - type dust removal device with a multi - stage dust removal effect, including a plurality of device bodies. The plurality of device bodies are connected by an air delivery pipe.

The bag cleaning mechanism includes side plates respectively sleeved on the reciprocating lead screw and the side lead screw. Cleaning disks are slidably sleeved outside each of the plurality of dust removal bags. The plurality of cleaning disks are connected into a whole through a connecting plate. The two side plates are respectively connected to the connecting plate. Wheel plates are arranged on both sides of each of the plurality of dust removal bags. The end of the wheel plate is fixedly connected to the mounting plate;

[0006] Both sides of the plurality of cleaning discs are fixedly connected with fixing plates. A roller is rotatably connected inside the fixing plate. The roller is in rolling contact with the corresponding wheel plate. A plurality of sliding rails are formed inside the roller. Trigger magnets are slidably connected to the inner side walls of the plurality of sliding rails. A pressing spring is arranged on the trigger magnet. One end of the pressing spring away from the trigger magnet is fixedly connected to the inner side wall of the sliding rail;

[0007] A top plate is slidably connected to the inner side wall of the fixing plate. A magnetic plate is arranged at the end of the top plate. The magnetic pole of the magnetic plate is the same as that of the trigger magnet. A gear is rotatably connected to the fixing plate. The gear is meshed with the top plate. A middle ring is arranged at the end of the top plate. A hard brush is arranged inside the middle ring;

[0008] A support plate is slidably connected inside the fixing plate. The support plate is meshed with the gear. Both sides of the end of the support plate are provided with tension springs. The other ends of the tension springs are fixedly connected to the fixing plate. A bottom ring is arranged at the end of the support plate. A soft brush is arranged inside the bottom ring.

[0009] Preferably, side grooves are formed inside both of the fixing plates. A knocking mechanism is arranged inside the side grooves.

[0010] Preferably, the knocking mechanism includes an intermittent contact plate slidably arranged inside the side groove. A turntable is rotatably connected inside the fixing plate. A synchronous belt is sleeved between the turntable and the roller. An oscillating arm is rotatably connected to the turntable. One end of the oscillating arm away from the turntable is rotatably connected to the outer side wall of the intermittent contact plate. A magnetic ring is arranged at the end of the intermittent contact plate.

[0011] Preferably, a top ring is arranged at the bottom of the cleaning disc. A plurality of knocking rods are slidably connected inside the top ring. Pressure springs are sleeved on the plurality of knocking rods. A contact magnet is arranged at the end of the knocking rod. The magnetic pole of the contact magnet is the same as that of the magnetic ring.

[0012] Preferably, a sewage storage tank is communicated with the bottom of each of the device main bodies. Maintenance doors are arranged on each of the device main bodies.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By setting up multiple device bodies, multi-stage filtration and separation of dust in the air can be carried out, making the air filtration and dust removal effect more thorough. At the same time, through the setting of mechanisms such as the cleaning plate, during use, the cleaning plate will move up and down on the surface of the dust removal cloth bag. When the surface of the dust removal cloth bag is relatively dry and the dust is easy to remove, at this time, the soft brush will contact the surface of the dust removal cloth bag during the movement of the cleaning plate, and clean and remove the dust on the surface of the dust removal cloth bag. If the surface of the dust removal cloth bag shows a phenomenon of moisture return, resulting in a certain adhesion ability of the dust and being difficult to remove, at this time, the soft brush will retract under the drive of the bottom ring, and the relatively hard hard brush will contact the surface of the dust removal cloth bag to clean the dust adhering to the surface of the dust removal cloth bag due to moisture return. By cleaning the dust on the surface of the dust removal cloth bag, the dust filtration effect of the entire device body can be ensured.

[0015] Through the setting of mechanisms such as the knocking rod, when the soft brush or the hard brush contacts the surface of the dust removal cloth bag to remove dust from the surface of the dust removal cloth bag, at this time, multiple knocking rods will gently knock the surface of the dust removal cloth bag under the magnetic drive, causing the dust removal cloth bag to vibrate slightly. This vibration not only helps to shake off the dust particles that are difficult to remove inside the cloth bag fibers, but also can shake off the dust that is agglomerated due to moisture, further improving the dust cleaning effect.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1: Please refer to Figure 1 - Figure 10 , a bag-type dust removal device with multi-stage dust removal effect, including a plurality of device main bodies 1, the plurality of device main bodies 1 are connected by an air delivery pipe 6, an air inlet pipe 2 is communicated and arranged on the outer side wall of the left device main body 1, an exhaust pipe 4 is communicated and arranged on the right device main body 1, a plurality of mounting plates 7 are fixedly connected inside the plurality of device main bodies 1, a plurality of dust removal cloth bags 8 are fixedly connected to the plurality of mounting plates 7, a reciprocating lead screw 10 and a side lead screw 11 are respectively rotatably connected inside the device main body 1, a driving motor 14 is arranged at the bottom of the reciprocating lead screw 10, a bottom connecting belt 15 is sleeved between the reciprocating lead screw 10 and the side lead screw 11, and a cloth bag cleaning mechanism is arranged on the reciprocating lead screw 10 and the side lead screw 11. The cloth bag cleaning mechanism includes side plates 9 respectively sleeved on the reciprocating lead screw 10 and the side lead screw 11, cleaning plates 12 are slidably sleeved outside the plurality of dust removal cloth bags 8, the plurality of cleaning plates 12 are connected into a whole through a connecting plate 13, the two side plates 9 are respectively connected to the connecting plate 13, wheel plates 16 are arranged on both sides of the plurality of dust removal cloth bags 8, and the ends of the wheel plates 16 are fixedly connected to the mounting plates 7.

[0029] On both sides of multiple cleaning plates 12, fixing plates 20 are fixedly connected. Inside the fixing plates 20, rollers 17 are rotatably connected. The rollers 17 are in rolling contact with the corresponding wheel plates 16. Inside the rollers 17, multiple sliding rails 18 are provided. On the inner side walls of the multiple sliding rails 18, trigger magnets 21 are slidably connected. On the trigger magnets 21, pressing springs 19 are provided. One end of the pressing spring 19 away from the trigger magnet 21 is fixedly connected to the inner side wall of the sliding rail 18.

[0030] On the inner side wall of the fixing plate 20, a top plate 25 is slidably connected. At the end of the top plate 25, a magnetic plate 26 is provided. The magnetic pole of the magnetic plate 26 is the same as that of the trigger magnet 21. On the fixing plate 20, a gear 24 is rotatably connected. The gear 24 is meshed with the top plate 25.

[0031] Inside the fixing plate 20, a support plate 23 is slidably connected. The support plate 23 is meshed with the gear 24. On both sides of the end of the support plate 23, tension springs 22 are provided. The other ends of the tension springs 22 are fixedly connected to the fixing plate 20.

[0032] In this embodiment, during use, the operator can convey the air to be filtered into the multiple device bodies 1 through the air inlet pipe 2. Multiple dust removal bags 8 are provided in each of the three device bodies 1. However, the filtration pore diameters of the dust removal bags 8 in the three device bodies 1 decrease in sequence from large to small. Therefore, when the air inlet pipe 2 conveys air into the three device bodies 1, the three device bodies 1 can perform multi-stage filtration on the air. Through multi-stage filtration and separation treatment, the air filtration and dust removal effect can be made more thorough. When a large amount of air is filtered by the dust removal bags 8 in the device body 1, resulting in a large amount of dust adhering to the surface, at this time, the operator can turn on the drive motor 14 to drive the reciprocating lead screw 10 to rotate. When the reciprocating lead screw 10 rotates, under the action of the belt 15 connected at the bottom, the side lead screw 11 will also rotate synchronously. When the side lead screw 11 rotates synchronously with the reciprocating lead screw 10, it will drive multiple cleaning plates 12 to move up and down on the surface of the dust removal bags 8 through the side plates 9.

[0033] When the cleaning plate 12 moves up and down on the surface of the dust removal cloth bag 8, the soft brush 39 located on the bottom ring 27 will contact the surface of the dust removal cloth bag 8, and scrape and clean the surface of the dust removal cloth bag 8 during the reciprocating movement of the cleaning plate 12 up and down, cleaning the dust attached to the surface of the dust removal cloth bag 8. The cleaned dust will naturally fall into the dirt storage box 5 and be collected by the dirt storage box 5. During the up and down movement of the cleaning plate 12, the roller 17 will contact and frictionally roll with the wheel plate 16. When the roller 17 rolls, it will drive the turntable 35 to rotate synchronously through the synchronous belt 40. When the turntable 35 rotates, it will make the intermittent contact plate 33 move up and down reciprocally in the side groove 34 through the swing arm 36. When the intermittent contact plate 33 moves up and down reciprocally, it will drive the magnetic ring 30 connected to it to move synchronously. When the magnetic ring 30 moves up and down reciprocally with the intermittent contact plate 33, it will intermittently be located on the side of the contact magnet 32. Since the magnetic poles of the magnetic ring 30 and the contact magnet 32 are the same, under the action of the intermittently repulsive magnetic force and the elastic force of the pressure spring 31, the knocking rod 37 will reciprocate on the top ring 29, knocking on the surface of the dust removal cloth bag 8, causing the dust removal cloth bag 8 to generate slight vibrations. The vibrations help to shake off the dust particles that are difficult to remove inside the cloth bag fibers.

[0034] Embodiment 2: Please refer to Figure 1 - Figure 10 , this embodiment further describes Embodiment 1. The end of the support plate 23 is provided with a bottom ring 27, and a soft brush 39 is arranged inside the bottom ring 27. The end of the top plate 25 is provided with a middle ring 28, and a hard brush 38 is arranged inside the middle ring 28.

[0035] Side grooves 34 are opened in the interiors of both sides of the fixed plates 20, and a knocking mechanism is arranged inside the side grooves 34.

[0036] The knocking mechanism includes an intermittent contact plate 33 slidably arranged inside the side groove 34. A turntable 35 is rotatably connected inside the fixed plate 20. A synchronous belt 40 is sleeved between the turntable 35 and the roller 17. A swing arm 36 is rotatably connected to the turntable 35. One end of the swing arm 36 away from the turntable 35 is rotatably connected to the outer side wall of the intermittent contact plate 33. A magnetic ring 30 is arranged at the end of the intermittent contact plate 33.

[0037] The bottom of the cleaning plate 12 is provided with a top ring 29. A plurality of knocking rods 37 are slidably connected inside the top ring 29. Pressure springs 31 are sleeved on the plurality of knocking rods 37. A contact magnet 32 is arranged at the end of the knocking rod 37, and the magnetic pole of the contact magnet 32 is the same as that of the magnetic ring 30.

[0038] The bottoms of a plurality of device bodies 1 are all communicated with a dirt storage box 5, and a maintenance door 3 is arranged on each of the plurality of device bodies 1.

[0039] In this embodiment, during the use process, if it is found that the surface of the dust removal cloth bag 8 shows a phenomenon of moisture return, at this time, the operator can increase the power of the driving motor 14 to drive the reciprocating lead screw 10 to rotate rapidly. When the reciprocating lead screw 10 rotates rapidly, it will drive a plurality of cleaning disks 12 to move rapidly up and down reciprocally on the surface of the dust removal cloth bag 8 through the side plate 9. When the cleaning disk 12 moves rapidly, the rotation speed of the roller 17 in contact with the wheel plate 16 will also increase. When the roller 17 rotates rapidly, under the action of a large centrifugal force, the trigger magnet 21 will overcome the elastic force of the pressing spring 19 and move to the outside of the roller 17. When the trigger magnet 21 located outside the roller 17 rotates to the front side of the magnetic force plate 26 along with the roller 17, at this time, under the action of the repulsive magnetic force, the top plate 25 will push the middle ring 28 to move towards the dust removal cloth bag 8 until it contacts the surface of the dust removal cloth bag 8. When the top plate 25 moves, under the action of the gear 24, the support plate 23 will drive the bottom ring 27 to move to the outside of the cleaning disk 12, so that the soft brush 39 on the bottom ring 27 no longer contacts the surface of the dust removal cloth bag 8. After the hard brush 38 on the middle ring 28 replaces the soft brush 39 and contacts the surface of the dust removal cloth bag 8, because the texture of the hard brush 38 is relatively hard, when it contacts the dust removal cloth bag 8, it can have a greater frictional force, so as to scrape the damp dust on the surface of the dust removal cloth bag 8. When the hard brush 38 scrapes the dust on the surface of the moisture-returned dust removal cloth bag 8 along with the cleaning disk 12, referring to the above principle, a plurality of knocking rods 37 will knock the surface of the dust removal cloth bag 8 more frequently than before. When the knocking rods 37 knock the surface of the dust removal cloth bag 8 frequently, the dust removal cloth bag 8 will vibrate slightly and frequently, so as to shake off the caked dust on the surface, and cooperate with the scraping of the hard brush 38 to make the dust removal effect better.

[0040] It should be noted that when the roller 17 rotates rapidly and throws a plurality of trigger magnets 21 to the outside of the roller 17, since the gap between the plurality of trigger magnets 21 is small and the length of the magnetic force plate 26 is long, when the plurality of trigger magnets 21 located outside the roller 17 rotate along with the roller 17, there will always be a trigger magnet 21 located on the side of the magnetic force plate 26. Therefore, as long as the roller 17 rotates rapidly, the magnetic force plate 26 will always be pushed by the repulsive magnetic force.

[0041] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
