Description

Technical Field

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

[0002] In a factory environment, especially in the processing of dusty air, dust removal devices are needed to maintain a good environment and the health of workers. Among them, bag dust removal is the most suitable. In order to better remove dust from the air, multi-stage treatment is required to better ensure the handling of dust.

[0003] After the bag-type 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-type dust removal mechanism, it is usually necessary to clean the dust on the surface of the bag. The existing cleaning technology usually adopts the technology of air blowing and recoil to remove the dust from the bag. However, the cleaning technology of air blowing and recoil has certain limitations when removing the dust from the bag. If the air entering the bag is at a low temperature or has a high water content, it will cause moisture desorption on the surface of the bag, causing the dust to adhere to the bag. This is because simple air blowing and recoil cannot blow away the dust on the surface of the bag, affecting the filtering effect of the entire bag. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects: Through the setting of multiple device bodies, the dust in the air can be subjected to multi-stage filtration and separation treatment, making the air filtration and dust removal effect more thorough. At the same time, through the setting of mechanisms such as the cleaning disc, when in use, the cleaning disc will reciprocate up and down on the surface of the dust bag.

By cleaning the dust on the surface of the dust bag, the dust filtration effect of the entire device body can be guaranteed.

[0014] Through the setting of mechanisms such as knocking rods, when the soft brush or the hard brush contacts the surface of the dust bag to remove dust, multiple knocking rods will gently knock on the surface of the dust bag under the drive of magnetic force, causing the dust bag to vibrate slightly. This vibration not only helps to shake off the dust particles that are difficult to remove inside the bag fibers, but also can shake off the dust that is damp and compacted together, further improving the cleaning effect.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figure 1 - Fig.10 A bag-type dust removal device with a multi-stage dust removal effect includes a plurality of device bodies 1, the plurality of device bodies 1 are connected by an air delivery pipe 6, an air inlet pipe 2 is connected on the outer wall of the left device body 1, and an exhaust pipe 4 is connected on the right device body 1, a plurality of mounting plates 7 are fixedly connected inside the plurality of device bodies 1, a plurality of dust removal bags 8 are fixedly connected on the plurality of mounting plates 7, a reciprocating screw 10 and a side screw 11 are rotatably connected inside the device body 1, and a driving motor 1 is provided at the bottom of the reciprocating screw 10 4. A bottom connecting belt 15 is sleeved between the reciprocating screw 10 and the side screw 11. A bag cleaning mechanism is arranged on the reciprocating screw 10 and the side screw 11. The bag cleaning mechanism includes side plates 9 respectively sleeved on the reciprocating screw 10 and the side screw 11. Cleaning discs 12 are slidably sleeved on the outside of the plurality of dust removal bags 8. The plurality of cleaning discs 12 are connected as a whole through a connecting plate 13. The side plates 9 on both sides are respectively connected to the connecting plates 13. Wheel plates 16 are arranged on both sides of the plurality of dust removal bags 8. The ends of the wheel plates 16 are fixedly connected to the mounting plate 7.

[0019] Both sides of the multiple cleaning discs 12 are fixedly connected with a fixed plate 20, and the interior of the fixed plate 20 is rotatably connected with a roller 17, and the roller 17 is in rolling contact with the corresponding wheel plate 16. A plurality of slide rails 18 are provided inside the roller 17, and the inner side walls of the plurality of slide rails 18 are slidably connected with a trigger magnet 21, and a pressing spring 19 is provided on the trigger magnet 21, and the end of the pressing spring 19 away from the trigger magnet 21 is fixedly connected to the inner side wall of the slide rail 18.

[0020] The inner wall of the fixed plate 20 is slidably connected with a top plate 25, and a magnetic plate 26 is provided at the end of the top plate 25. The magnetic poles of the magnetic plate 26 are the same as the magnetic poles of the trigger magnet 21. A gear 24 is rotatably connected to the fixed plate 20, and the gear 24 and the top plate 25 are meshed.

[0021] A support plate 23 is slidably connected inside the fixed plate 20 . The support plate 23 is meshed with a gear 24 . Tension springs 22 are provided on both sides of the end of the support plate 23 . The other end of the tension spring 22 is fixedly connected to the fixed plate 20 .

[0022] In the present embodiment, when in use, the operator can transport the air to be filtered into the multiple device bodies 1 through the air intake pipe 2. The three device bodies 1 are each provided with a plurality of dust removal bags 8, but the filter apertures of the dust removal bags 8 in the three device bodies 1 are arranged from large to small. Therefore, when the air intake pipe 2 passes air into the three device bodies 1, the three device bodies 1 can perform multi-stage filtration on the air. The multi-stage filtration and separation treatment can make the air filtration and dust removal effect more thorough. When the dust removal bags 8 in the device body 1 filter more air, resulting in more dust attached to the surface, the operator can turn on the drive motor 14 to drive the reciprocating screw 10 to rotate. When the reciprocating screw 10 rotates, under the action of the bottom connecting belt 15, the side screw 11 will also rotate synchronously. When the side screw 11 rotates synchronously with the reciprocating screw 10, it will drive the multiple cleaning discs 12 to move up and down on the surface of the dust removal bag 8 through the side plate 9.

[0023] When the cleaning disc 12 moves up and down on the surface of the dust bag 8, the soft brush 39 on the bottom ring 27 will contact the surface of the dust bag 8, and scrape and clean the surface of the dust bag 8 during the up and down reciprocating movement of the cleaning disc 12, and clean the dust attached to the surface of the dust 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 disc 12, the roller 17 will contact and 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 allow the swing arm 36 to move. The intermittent contact plate 33 reciprocates up and down in the side groove 34. When the intermittent contact plate 33 reciprocates up and down, it will drive the magnetic ring 30 connected to it to move synchronously. When the magnetic ring 30 reciprocates up and down with the intermittent contact plate 33, it will be intermittently 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 intermittent repulsive magnetic force and the elastic force of the pressure spring 31, the knocking rod 37 will reciprocate on the top ring 29, knocking the surface of the dust bag 8, causing the dust bag 8 to produce slight vibrations. The vibration helps to shake off the dust particles that are difficult to remove from the bag fibers.

[0024] Example 2: Please refer to Figure 1 - Fig.10 This embodiment further explains the first embodiment. A bottom ring 27 is provided at the end of the support plate 23. A soft brush 39 is provided inside the bottom ring 27. A middle ring 28 is provided at the end of the top plate 25. A hard brush 38 is provided inside the middle ring 28.

[0025] Side grooves 34 are formed inside the fixing plates 20 on both sides, and a knocking mechanism is disposed inside the side grooves 34 .

[0026] 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, and one end of the swing arm 36 away from the turntable 35 is rotatably connected to the outer wall of the intermittent contact plate 33, and a magnetic ring 30 is arranged at the end of the intermittent contact plate 33.

[0027] A top ring 29 is provided at the bottom of the cleaning disk 12, and 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, and a contact magnet 32 ​​is provided at the end of the knocking rod 37. The magnetic poles of the contact magnet 32 ​​are the same as those of the magnetic ring 30.

[0028] The bottoms of the multiple device bodies 1 are all connected to each other and are provided with a dirt storage box 5 . The multiple device bodies 1 are all provided with an inspection door 3 .

[0029] In this embodiment, during use, if it is found that the surface of the dust bag 8 has moisture dehumidification, the operator can increase the power of the driving motor 14 to drive the reciprocating screw 10 to rotate rapidly. When the reciprocating screw 10 rotates rapidly, it will drive multiple cleaning discs 12 to move rapidly up and down on the surface of the dust bag 8 through the side plates 9. When the cleaning discs 12 move rapidly, the 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 on the outside of the roller 17 rotates to the positive side of the magnetic plate 26 with the roller 17, under the action of the repelling magnetic force, the top plate 25 will push the middle ring 28 to move in the direction close to the dust bag 8 until it contacts the surface of the dust 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 toward 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 bag 8. After the hard brush 38 on the middle ring 28 replaces the soft brush 39 to contact the surface of the dust bag 8, due to the relatively hard texture of the hard brush 38, it can have a greater friction when in contact with the dust bag 8, thereby being able to scrape the damp dust on the surface of the dust bag 8. When the hard brush 38 scrapes the dust on the surface of the anti-humid dust bag 8 with the cleaning disk 12, referring to the above principle, the multiple knocking rods 37 will knock on the surface of the dust bag 8 at a higher frequency than before. When the knocking rods 37 knock on the surface of the dust bag 8 at a high frequency, the dust bag 8 will perform a small-amplitude high-frequency vibration, thereby shaking off the compacted dust on the surface. Combined with the scraping and dust removal of the hard brush 38, the dust removal effect can be better.

[0030] It should be noted that when the roller 17 rotates rapidly and throws multiple trigger magnets 21 to the outside of the roller 17, since the gaps between the multiple trigger magnets 21 are small and the length of the magnetic plate 26 is long, when the multiple trigger magnets 21 located on the outside of the roller 17 rotate with the roller 17, there will always be trigger magnets 21 located on the side of the magnetic plate 26. Therefore, as long as the roller 17 rotates rapidly, the magnetic plate 26 will always be pushed by the repulsive magnetic force.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
