Description

Technical Field

[0001] This utility model belongs to the field of filtration equipment technology, specifically relating to an antistatic dust filter. Background Technology

[0002] An antistatic dust filter is a device specifically designed to capture and remove statically charged dust particles from the air. In industrial production, dust in certain environments may become statically charged due to friction, which can not only affect product quality but also pose safety hazards such as fires or explosions. Therefore, the use of antistatic dust filters in these environments is essential.

[0003] Traditional antistatic dust filters require frequent filter element replacements to ensure proper filter operation, making them rather inconvenient to use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an antistatic dust filter. This utility model can clean the filter element when the filter is working, effectively reducing the number of filter element replacements, extending the service life of the filter, reducing the frequency of filter maintenance, and improving work efficiency.

[0005] The technical solution adopted to solve the above technical problems is: an antistatic dust filter, including a housing and a filter cartridge, wherein the filter cartridge is fixedly installed in the housing, an air inlet is provided on the side of the housing, an air outlet is provided on the top of the housing, and a dust discharge port is provided at the bottom of the housing. A cleaning mechanism is slidably connected to the filter cartridge, and an electric push rod is fixedly connected to the bottom of the housing. The electric push rod can drive the cleaning mechanism to slide vertically.

[0006] Guide rods are symmetrically fixedly connected to the front and rear sides of the housing. The guide rods pass through the cleaning mechanism, and the cleaning mechanism is slidably connected to the guide rods.

[0007] With the above technical solution, unfiltered air enters the housing through the air inlet, and then the unfiltered air is filtered through the filter cartridge. The filtered air is discharged through the air outlet. During the filtration process, the filter cartridge adsorbs dust. Excessive dust accumulation can affect air passage. The cleaning mechanism slides vertically on the filter cartridge to clean it, removing the dust. The dust is deposited at the bottom of the housing and finally discharged through the dust outlet. The filter effectively filters dust while cleaning the filter cartridge, reducing the frequency of filter cartridge replacement and increasing the service life of the filter cartridge.

[0008] Furthermore, the cleaning mechanism includes a base, a cleaning ring, a first transmission rod, and a second transmission rod. The cleaning ring is rotatably connected to the base, and the first and second transmission rods are rotatably connected to one side of the base. The guide rod passes through the front and rear sides of the base, and the base is slidably connected to the guide rod.

[0009] With the above technical solution, since the cleaning ring is rotatably connected to the base, the first transmission rod and the second transmission rod are rotatably connected to one side of the base, the guide rod passes through the front and rear sides of the base, and the base is slidably connected to the guide rod, the cleaning ring can rotate on the base while the base slides vertically on the guide rod.

[0010] Furthermore, the top of the electric push rod is fixedly connected to one side of the base, and the top of the electric push rod is fixedly connected to the side of the base away from the first transmission rod and the second transmission rod.

[0011] Through the above technical solution, the extension and retraction of the electric push rod can drive the base to slide vertically on the guide rod.

[0012] Furthermore, a drive rack is fixedly connected to one side of the housing, and the drive rack is located inside the housing near the first transmission rod and the second transmission rod.

[0013] With the above technical solution, the cleaning mechanism will not interfere with the drive rack when sliding vertically.

[0014] Furthermore, a plurality of cleaning teeth are fixedly connected at equal intervals inside the cleaning ring, and a beveled ring is fixedly connected to the top of the cleaning ring.

[0015] With the above technical solution, because multiple cleaning teeth are fixedly connected at equal intervals inside the cleaning ring, the cleaning ring can clean the filter cartridge when it rotates.

[0016] Furthermore, a first bevel gear is fixedly connected to one end of the first transmission rod, a second bevel gear is fixedly connected to the other end of the first transmission rod, a third bevel gear is fixedly connected to one end of the second transmission rod, and a driven gear is fixedly connected to the other end of the second transmission rod. The first bevel gear meshes with a bevel gear ring, the second bevel gear meshes with the third bevel gear, and the driven gear meshes with a drive rack.

[0017] Through the above technical solution, since a driven gear is fixedly connected to the other end of the second transmission rod, the first bevel gear meshes with the bevel gear ring, the second bevel gear meshes with the third bevel gear, and the driven gear meshes with the drive rack, when the base slides vertically, the drive rack can drive the driven gear to rotate. The rotation of the driven gear causes the second transmission rod to rotate, the rotation of the second transmission rod drives the third bevel gear to rotate, the rotation of the third bevel gear can drive the second bevel gear to rotate, the rotation of the second bevel gear causes the first transmission rod to rotate, the rotation of the first transmission rod drives the first bevel gear to rotate, the rotation of the first bevel gear can drive the bevel gear ring to rotate, and the rotation of the bevel gear ring can drive the cleaning ring to rotate on the base. Ultimately, while the cleaning mechanism slides vertically, the cleaning ring rotates on the base, which can thoroughly clean the filter cartridge and effectively improve the cleaning effect.

[0018] Furthermore, a grounding connector is fixedly provided at the bottom of the housing, and the drive rack is fixedly connected to the grounding connector.

[0019] With the above technical solution, since a grounding connector is fixedly installed at the bottom of the housing, and the drive rack is fixedly connected to the grounding connector, the static charge carried by the dust in the filter is conducted to the ground after the grounding connector is connected to the ground wire, effectively eliminating static electricity. The drive rack is in contact with the cleaning mechanism, which can effectively eliminate the static electricity generated by friction when the cleaning mechanism cleans the filter cartridge, ensuring the elimination effect of static electricity.

[0020] The beneficial effects of this utility model are as follows:

[0021] (1) In this utility model, the filter cartridge adsorbs dust during the filtration process. Excessive dust accumulation will affect the passage of air. The cleaning mechanism can clean the filter cartridge by sliding vertically on the filter cartridge. The dust on the filter cartridge can be removed and deposited at the bottom of the housing. Finally, the dust is discharged through the ash discharge port. The filter effectively filters dust while cleaning the filter cartridge, reducing the number of filter cartridge replacements and increasing the service life of the filter cartridge.

[0022] (2) When the base slides vertically in this utility model, the drive rack can drive the driven gear to rotate. The rotation of the driven gear causes the second transmission rod to rotate. The rotation of the second transmission rod drives the third bevel gear to rotate. The rotation of the third bevel gear can drive the second bevel gear to rotate. The rotation of the second bevel gear causes the first transmission rod to rotate. The rotation of the first transmission rod drives the first bevel gear to rotate. The rotation of the first bevel gear can drive the bevel gear ring to rotate. The rotation of the bevel gear ring can drive the cleaning ring to rotate on the base. Finally, while the cleaning mechanism slides vertically, the cleaning ring rotates on the base, which can thoroughly clean the filter cartridge, effectively improve the cleaning effect, and increase the service life of the filter cartridge.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] like Figure 1 - Figure 2 As shown, an antistatic dust filter includes a housing 1 and a filter cartridge 2. The filter cartridge 2 is fixedly installed inside the housing 1. An air inlet 11 is provided on the side of the housing 1, an air outlet 12 is provided on the top of the housing 1, and a dust discharge outlet 13 is provided on the bottom of the housing 1. A cleaning mechanism 3 is slidably connected to the filter cartridge 2, and an electric push rod 6 is fixedly connected to the bottom of the housing 1. The electric push rod 6 can drive the cleaning mechanism 3 to slide vertically.

[0032] Guide rods 4 are symmetrically fixedly connected to the front and rear sides of the housing 1. The guide rods 4 pass through the cleaning mechanism 3, and the cleaning mechanism 3 is slidably connected to the guide rods 4.

[0033] In this embodiment, unfiltered air enters the housing 1 through the air inlet 11, and then the unfiltered air is filtered through the filter cartridge 2. The filtered air is discharged through the air outlet 12. During the filtration process, the filter cartridge 2 adsorbs dust. Excessive dust accumulation will affect the passage of air. The cleaning mechanism 3 can clean the filter cartridge 2 by sliding vertically on it, removing the dust from the filter cartridge 2. The dust is deposited at the bottom of the housing 1 and finally discharged through the dust discharge port 13. The filter effectively filters dust while cleaning the filter cartridge 2, reducing the number of times the filter cartridge 2 needs to be replaced and increasing the service life of the filter cartridge 2.

[0034] like Figure 1 - Figure 5 As shown, the cleaning mechanism 3 includes a base 31, a cleaning ring 32, a first transmission rod 33 and a second transmission rod 34. The cleaning ring 32 is rotatably connected to the base 31. The first transmission rod 33 and the second transmission rod 34 are rotatably connected to one side of the base 31. The guide rod 4 passes through the front and rear sides of the base 31. The base 31 is slidably connected to the guide rod 4.

[0035] The top of the electric push rod 6 is fixedly connected to one side of the base 31, and the top of the electric push rod 6 is fixedly connected to the side of the base 31 away from the first transmission rod 33 and the second transmission rod 34.

[0036] A drive rack 5 is fixedly connected to one side of the housing 1. The drive rack 5 is located inside the housing 1 on the side close to the first transmission rod 33 and the second transmission rod 34.

[0037] Multiple cleaning teeth 321 are fixedly connected at equal intervals inside the cleaning ring 32, and a beveled ring 322 is fixedly connected to the top of the cleaning ring 32.

[0038] One end of the first transmission rod 33 is fixedly connected to a first bevel gear 331, and the other end of the first transmission rod 33 is fixedly connected to a second bevel gear 332. One end of the second transmission rod 34 is fixedly connected to a third bevel gear 341, and the other end of the second transmission rod 34 is fixedly connected to a driven gear 342. The first bevel gear 331 meshes with the bevel gear ring 322, the second bevel gear 332 meshes with the third bevel gear 341, and the driven gear 342 meshes with the drive rack 5.

[0039] In this embodiment, the extension and retraction of the electric push rod 6 can drive the base 31 to slide vertically on the guide rod 4. When the base 31 slides vertically, the drive rack 5 can drive the driven gear 342 to rotate. The rotation of the driven gear 342 causes the second transmission rod 34 to rotate. The rotation of the second transmission rod 34 drives the third bevel gear 341 to rotate. The rotation of the third bevel gear 341 can drive the second bevel gear 332 to rotate. The rotation of the second bevel gear 332 causes the first transmission rod 33 to rotate. The rotation of the first transmission rod 33 drives the first bevel gear 331 to rotate. The rotation of the first bevel gear 331 can drive the bevel gear ring 322 to rotate. The rotation of the bevel gear ring 322 can drive the cleaning ring 32 to rotate on the base 31. Finally, while the cleaning mechanism 3 slides vertically, the cleaning ring 32 rotates on the base 31, which can thoroughly clean the filter cartridge 2 and effectively improve the cleaning effect.

[0040] like Figure 5 - Figure 6 As shown, a grounding connector 14 is fixedly installed at the bottom of the housing 1, and the drive rack 5 is fixedly connected to the grounding connector 14.

[0041] In this embodiment, after the grounding connector 14 is connected to the ground wire, the static charge carried by the dust in the filter is conducted to the ground, effectively eliminating static electricity. The drive rack 5 contacts the cleaning mechanism 3, which can effectively eliminate the static electricity generated by friction when the cleaning mechanism 3 cleans the filter cartridge 2, ensuring the elimination effect of static electricity.

[0042] Working principle:

[0043] During operation, unfiltered air enters the housing 1 through the air inlet 11, and then the unfiltered air is filtered through the filter cartridge 2. The filtered air is discharged through the air outlet 12.

[0044] Filter cartridge 2 adsorbs dust during the filtration process; excessive dust accumulation can affect air passage.

[0045] When cleaning is required, the electric push rod 6 is activated. The extension and retraction of the electric push rod 6 can drive the base 31 to slide vertically on the guide rod 4. When the base 31 slides vertically, the drive rack 5 can drive the driven gear 342 to rotate. The rotation of the driven gear 342 causes the second transmission rod 34 to rotate. The rotation of the second transmission rod 34 drives the third bevel gear 341 to rotate. The rotation of the third bevel gear 341 can drive the second bevel gear 332 to rotate. The rotation of the second bevel gear 332 causes the first transmission rod 33 to rotate. The rotation of the first transmission rod 33 drives the first bevel gear 331 to rotate. The rotation of the first bevel gear 331 can drive the bevel gear ring 322 to rotate. The rotation of the bevel gear ring 322 can drive the cleaning ring 32 to rotate on the base 31. Finally, the cleaning mechanism 3 slides vertically while the cleaning ring 32 rotates on the base 31, which can thoroughly clean the filter cartridge 2 and effectively improve the cleaning effect.

[0046] After the grounding connector 14 is connected to the ground wire, the static charge carried by the dust in the filter is conducted to the ground, effectively eliminating static electricity. Meanwhile, the drive rack 5 comes into contact with the cleaning mechanism 3, which can effectively eliminate the static electricity generated by friction when the cleaning mechanism 3 cleans the filter cartridge 2, ensuring the elimination of static electricity.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
