Description

Technical Field

[0001] This utility model relates to the field of air purification equipment in factories, and more particularly to a dust removal device with high cleanliness. Background Technology

[0002] In the processing and production of factories, there are certain environmental protection requirements for the factory environment, such as treating the exhaust gas generated by some equipment before it is discharged.

[0003] Some equipment requires additional air during production, such as hot air drying or cold air cooling equipment. However, the air may contain pollutants or solid particles. When these substances enter the equipment, they can cause defective products and damage to the equipment to varying degrees.

[0004] Although there are some dust removal devices on the market, these devices generally have the problem of high cost, which makes subsequent maintenance and replacement difficult. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a dust removal device with high cleanliness.

[0006] The technical solution of this utility model is: a high-cleanliness dust removal device, comprising:

[0007] A frame is provided on which a dust removal assembly is mounted, the dust removal assembly comprising:

[0008] A dust collection bin is provided with an air inlet and an air outlet. The air inlet is connected to unpurified air, and the air outlet is the outlet for purified air.

[0009] An air inlet baffle is installed inside the dust collector and is located between the air inlet and the air outlet. The upper side of the air inlet baffle is connected to the inner wall, while the lower side is open. There is a gap between the air inlet baffle and the inner wall of the dust collector, and an air inlet is provided on the outer wall of the dust collector corresponding to the gap. Unpurified air enters the gap from the air inlet and comes into contact with the air inlet baffle.

[0010] The filter element is detachably installed inside the dust collection bin and is also connected to the air outlet.

[0011] A ash bucket is located below and connected to the dust collection bucket.

[0012] Furthermore, the air inlet baffle is arranged in a ring shape, and a centrifugal channel is formed between the air inlet baffle and the inner wall of the dust collector. Through the centrifugal channel, dust and other impurities can be directly separated by the circular channel.

[0013] Furthermore, the air inlet is lower than the air outlet. This different height setting allows impurities in the air to fall from top to bottom into the ash bin under the influence of gravity due to the different weights of the impurities and the gas, thus achieving automatic descent.

[0014] Furthermore, the air inlet baffle includes a connecting part and a shielding part. The connecting part is connected to the inside of the dust collector, and the shielding part forms a gap with the inner wall of the dust collector. The size and space of the gap can be controlled by the design of both ends.

[0015] Furthermore, the upper side of the air inlet baffle is inclined, and it slopes radially inward and downward. This inclined slope design allows debris from the filter element to fall naturally into the ash bin.

[0016] Furthermore, an installation plate is provided inside the dust collection bin, and a filter element is installed on the installation plate. The installation plate and the air outlet are in an independent space, communicating only with the interior of the dust collection bin through the filter element. This ensures that the air is filtered before being discharged.

[0017] Furthermore, a support frame is provided to cooperate with the filter element. The support frame is set inside the dust collection bin, and the filter element is sleeved on the support frame. A cover plate is set on the outside of the filter element, covering the outside of the dust collection bin. A connecting screw rod passes through the center of the cover plate, and a handle is set on the outside of the connecting screw rod. The inside of the connecting screw rod is threaded to the support frame. This threaded connection method achieves stable installation of the filter element.

[0018] Furthermore, the lower side of the dust collection bin is funnel-shaped and gradually tapers inward. This inclined design ensures that dust can smoothly enter the dust bin.

[0019] Furthermore, an automatic closing component is provided at the lower opening of the dust collection bin, the automatic closing component comprising:

[0020] A rotating shaft, which is fixedly mounted on the dust collection bin;

[0021] A cover plate, wherein the cover plate is rotatably mounted on a rotating shaft;

[0022] A counterweight is mounted on a cover plate and located on one side of the rotating shaft. Under the action of the counterweight, the cover plate covers the lower opening of the dust collection bin, thus achieving automatic sealing.

[0023] Furthermore, two automatic closing components are provided, and each cover plate is semi-circular. This ensures that if one fails, the other can still function normally.

[0024] Furthermore, a voltage stabilizing component is also provided, which includes a voltage stabilizing pipe. One side of the voltage stabilizing pipe is connected to the inside of the dust collection bin, and the other side of the voltage stabilizing pipe is connected to the ash bin.

[0025] Furthermore, a three-way valve is installed at the location of the ash bucket, with one valve connected to the ash bucket, the second connected to the pressure stabilizing pipe, and the third connected to the air. When connected to the ash bucket, the pressure is consistent, and the automatic closing component will automatically open and close under the action of gravity; when connected to the outside, there is negative pressure above and normal pressure inside the ash bucket, which ensures the stability of the automatic closing component.

[0026] The beneficial technical effects of this utility model are: by setting the air inlet baffle, the air is forced to rotate centrifugally after entering, that is, the dust naturally slows down and falls after hitting the inner wall. The air purified once enters the filter element, and after secondary filtration, it is blown out from the air outlet, which ensures the efficiency of air purification and improves the service life of the filter element, thus providing a guarantee for subsequent use or air purification.

[0041] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0042] See appendix Figure 1-6 The high-cleanliness dust removal equipment shown includes: a frame 1, on which a dust removal assembly is mounted, the dust removal assembly including: a dust collection bin 2, with an air inlet 21 and an air outlet 22 on the dust collection bin 2, the air inlet 21 connecting to unpurified air, and the air outlet 22 being the outlet for purified air; an air inlet baffle 3, which is disposed inside the dust collection bin 2 and located between the air inlet 21 and the air outlet 22, the upper side of the air inlet baffle 3 being connected to the inner wall, while the lower side being open, and a gap between the air inlet baffle 3 and the inner wall of the dust collection bin 2, with the air inlet 21 located on the outer wall of the dust collection bin 2 corresponding to the gap, allowing unpurified air to enter the gap from the air inlet 21 and come into contact with the air inlet baffle 3; a filter element 4, which is detachably disposed inside the dust collection bin 2 and is also connected to the air outlet 22; and an ash bin 5, which is located below the dust collection bin 2 and is connected to the dust collection bin 2. The air inlet baffle 3 is arranged in a ring shape, and the air inlet baffle 3 and the inner wall of the dust collector 2 form a centrifugal channel 31. Through the arrangement of the centrifugal channel 31, dust and other impurities can be directly separated under the action of the circular channel.

[0043] By setting the air inlet baffle 3, the air is forced to rotate centrifugally after entering. This means that the dust will naturally slow down and fall after hitting the inner wall. The air after primary purification enters the filter element 4, and after secondary filtration, it is blown out from the air outlet 22. This ensures the efficiency of air purification and also improves the service life of the filter element 4, providing a guarantee for subsequent use or air purification.

[0044] Furthermore, the air inlet 21 is lower than the air outlet 22. This different height setting allows impurities in the air to fall from top to bottom into the ash bin 5 under the action of gravity due to the different weights of the impurities and the gas, thus achieving automatic descent.

[0045] Furthermore, the air inlet baffle 3 includes a connecting part and a blocking part. The connecting part is connected to the inside of the dust collector 2, and a gap is formed between the blocking part and the inner wall of the dust collector 2. The size and space of the gap can be controlled by the design of both ends.

[0046] Furthermore, the upper side of the air inlet baffle 3 is inclined and slopes radially inward and downward. This inclined slope design allows debris from the filter element 4 to fall naturally into the ash bin 5.

[0047] Furthermore, an installation plate 6 is installed inside the dust collection bin 2, and a filter element 4 is installed on the installation plate 6. The installation plate 6 and the air outlet 22 are in an independent space, and the dust collection bin 2 is only connected through the filter element 4. This ensures that the air is filtered by the filter element 4 before being discharged.

[0048] Furthermore, a support frame 7 is provided to cooperate with the filter element 4. The support frame 7 is set inside the dust collection bin 2, and the filter element 4 is sleeved on the support frame. A cover plate 71 is provided on the outside of the filter element 4, covering the outside of the dust collection bin 2. At the same time, a connecting screw 72 passes through the middle of the cover plate, and a handle 73 is provided on the outside of the connecting screw 72. The inside of the connecting screw is threadedly connected to the support frame 7. Through this threaded connection, the filter element 4 is stably installed.

[0049] Furthermore, the lower side of the dust collection bin 2 is funnel-shaped and gradually tapers inward. This inclined design ensures that dust can smoothly enter the dust bin 5.

[0050] Furthermore, an automatic closing component 8 is provided at the lower opening of the dust collection bin 2, the automatic closing component 8 comprising:

[0051] Rotating shaft 81 is fixedly mounted on dust collection bin 2;

[0052] Cover plate 82, which is rotatably mounted on rotating shaft 81;

[0053] A counterweight 83 is mounted on a cover plate 82 and is located on one side of the rotating shaft 81. Under the action of the counterweight 83, the cover plate 82 covers the lower opening of the dust collection bin 2, thus achieving automatic sealing.

[0054] Furthermore, two automatic closing components 8 are provided, and each cover plate 82 is semi-circular. This ensures that if one fails, the other can still function normally.

[0055] Furthermore, a pressure stabilizing component is also provided, which includes a pressure stabilizing pipe 9. One side of the pressure stabilizing pipe 9 is connected to the inside of the dust collection bin 2, and the other side of the pressure stabilizing pipe 9 is connected to the ash bin 5.

[0056] Furthermore, a three-way valve 91 is installed at the position of the ash bucket 5, with one valve connected to the ash bucket 5, the second connected to the pressure stabilizing pipe 9, and the third connected to the air. When connected to the ash bucket 5, the pressure is consistent, and the automatic closing component 8 will automatically open and close under the action of gravity; when connected to the outside, there is negative pressure above and normal pressure inside the ash bucket 5, which ensures the stability of the automatic closing component 8.
