Description

Technical Field

[0001] This utility model relates to the field of dust collector filter cartridge technology, and in particular to a flow guiding device for a dust collector filter cartridge. Background Technology

[0002] Dust collector filter cartridges are the core components of industrial dust removal systems. They are mainly used to capture pollutants such as dust and particulate matter and are widely used in steel plants and cement plants. Their structure is usually made of filter media cartridges (such as polyester fiber, glass fiber, etc.) folded into a corrugated shape, with metal filter tubes installed inside. They have the characteristics of large filtration area, low resistance, and high dust removal efficiency.

[0003] The above-mentioned and existing technologies have the following drawbacks: When producing dust collector filter cartridges, glue is used to bond the filter tube and the filter media cartridge together. Therefore, when the filter media cartridge of the dust collector filter cartridge is replaced later, even if the metal filter tube can still be used normally, the filter tube cannot be separated from the filter media cartridge, so the entire filter cartridge can only be replaced, which increases the cost of use.

[0004] Therefore, a flow guiding device for a dust collector filter cartridge is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that when replacing the filter media cartridge of a dust collector, even if the metal filter tube can still be used normally, the filter tube cannot be separated from the filter media cartridge, so only the entire filter cartridge can be replaced. Therefore, a flow guiding device for a dust collector filter cartridge is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flow guiding device for a dust collector filter cartridge, comprising a filter tube, wherein a flow guiding liner is fixedly mounted on the inner circumferential surface of the filter tube, a retaining ring is fixedly mounted on one end of the filter tube, a filter material cylinder is slidably sleeved on the outer circumferential surface of the filter tube, a pressure ring is threadedly connected to the outer circumferential surface of the filter tube, and a first ring and a second ring are fixedly mounted on both ends of the filter material cylinder, wherein the first ring and the second ring are both slidably sleeved on the outer circumferential surface of the filter tube.

[0007] The effect achieved by the above components is that, by setting up components such as filter tube, filter media cylinder, pressure ring, first ring and second ring, when replacing the filter media cylinder, the filter tube and filter media cylinder are designed separately, so it is not necessary to replace them together, thereby reducing the cost of use and avoiding waste of resources.

[0008] Preferably, a first sealing ring is fixedly mounted on the surface of the first ring, and the first sealing ring abuts against the surface of the retaining ring; a second sealing ring is fixedly mounted on the surface of the second ring, and the second sealing ring abuts against the surface of the pressure ring.

[0009] The effects achieved by the above components are as follows: the first sealing ring can improve the sealing performance between the first ring and the retaining ring, and the second sealing ring can improve the sealing performance between the second ring and the pressure ring.

[0010] Preferably, a plurality of support rods are inserted inside the filter media cylinder, and the two ends of the support rods are fixedly connected to the first ring and the second ring, respectively.

[0011] The effect achieved by the above components is that the support rod can improve the compressive strength of the filter media cartridge and prevent the filter media cartridge from being damaged due to the compression of the pressure ring.

[0012] Preferably, a retaining block is fixedly mounted on the surface of the retaining ring, and the retaining block is slidably connected to the first ring.

[0013] The effect achieved by the above components is that when the first ring contacts the locking block, the locking block can restrict the position of the first ring, thereby restricting the position of the filter media cartridge.

[0014] Preferably, the circumferential surface of the pressure ring is provided with a plurality of anti-slip grooves.

[0015] The effect achieved by the above components is that the pressure ring can be easily rotated through the anti-slip groove.

[0016] Preferably, the circumferential surface of the card block is slidably fitted with a protective sleeve, the filter media cylinder is located inside the protective sleeve, and the two ends of the protective sleeve abut against the surfaces of the first ring and the second ring, respectively.

[0017] The effect achieved by the above-mentioned components is that, during the transportation of the filter cartridge, the protective sleeve can shield and protect the filter cartridge, preventing the filter cartridge from being squeezed and deformed or even broken.

[0018] Preferably, a limiting ring is fixedly mounted on the surface of the pressure ring, and the limiting ring is slidably connected to the inner circumferential surface of the protective sleeve.

[0019] The effect achieved by the above components is that after the inner circumferential surface of the protective sleeve abuts against the circumferential surface of the locking block and the limiting ring, the position of the protective sleeve will be restricted, thereby maintaining a certain distance between the protective sleeve and the filter media cartridge.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, by setting up components such as filter tube, filter media cylinder, pressure ring, first ring and second ring, when replacing the filter media cylinder, the filter tube and filter media cylinder are designed separately, so it is not necessary to replace the filter tube together, thereby reducing the cost of use and avoiding waste of resources.

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0032] like Figures 1-7As shown, this utility model provides a flow guiding device for a dust collector filter cartridge, including a filter tube 1. A flow guiding liner 14 is fixedly mounted on the inner circumferential surface of the filter tube 1. A retaining ring 2 is fixedly mounted on one end of the filter tube 1. A filter media cylinder 3 is slidably sleeved on the outer circumferential surface of the filter tube 1. A pressure ring 4 is threadedly connected to the outer circumferential surface of the filter tube 1. A first ring 5 and a second ring 6 are fixedly mounted on both ends of the filter media cylinder 3, respectively. Both the first ring 5 and the second ring 6 are slidably sleeved on the outer circumferential surface of the filter tube 1. By setting the filter tube 1, filter media cylinder 3, pressure ring 4, first ring 5 and second ring 6, etc., When replacing the filter media cartridge 3, the filter tube 1 and filter media cartridge 3 are designed separately, so it is not necessary to replace the filter tube 1 together, thereby reducing the cost of use and avoiding waste of resources. The surface of the first ring 5 is fixedly fitted with a first sealing ring 7, which abuts against the surface of the retaining ring 2. The surface of the second ring 6 is fixedly fitted with a second sealing ring 8, which abuts against the surface of the pressure ring 4. The first sealing ring 7 can improve the sealing between the first ring 5 and the retaining ring 2, and the second sealing ring 8 can improve the sealing between the second ring 6 and the pressure ring 4.

[0033] Several support rods 9 are inserted inside the filter media cartridge 3. The two ends of each support rod 9 are fixedly connected to the first ring 5 and the second ring 6, respectively. The support rods 9 improve the compressive strength of the filter media cartridge 3, preventing damage due to compression from the pressure ring 4. A locking block 10 is fixedly mounted on the surface of the retaining ring 2. The locking block 10 is slidably connected to the first ring 5. When the first ring 5 contacts the locking block 10, the locking block 10 restricts the position of the first ring 5, thereby restricting the position of the filter media cartridge 3. Several anti-slip grooves 11 are formed on the circumferential surface of the pressure ring 4, allowing for convenient rotation of the pressure ring 4 and the locking block 10. The sliding sleeve is equipped with a protective sleeve 12, and the filter media cylinder 3 is located inside the protective sleeve 12. The two ends of the protective sleeve 12 abut against the surfaces of the first ring 5 and the second ring 6, respectively. During the transport of the filter media cylinder, the protective sleeve 12 can shield and protect the filter media cylinder 3, preventing the filter media cylinder 3 from being squeezed and deformed or even broken. The surface of the pressure ring 4 is fixedly equipped with a limiting ring 13, which is slidably connected to the inner circumferential surface of the protective sleeve 12. After the inner circumferential surface of the protective sleeve 12 abuts against the circumferential surface of the locking block 10 and the limiting ring 13, the position of the protective sleeve 12 will be restricted, thereby maintaining a certain distance between the protective sleeve 12 and the filter media cylinder 3.

[0034] The overall working principle is as follows: During dust removal, when gas passes through the filter media cartridge 3, dust is intercepted on the surface of the filter media cartridge 3, while the filtered gas enters the filter tube 1. The filter tube 1 further filters the gas entering the filter media cartridge 3. When it is necessary to clean the filter media cartridge 3, air passes through the guide liner 14 and then flows from the filter tube 1 into the filter media cartridge 3, blowing out the dust inside the filter media cartridge 3, thereby achieving the purpose of cleaning the filter media cartridge 3. By setting the guide liner 14, the functions are firstly to reduce the internal volume of the filter tube 1, and secondly to allow the airflow to flow into the inside of the filter tube 1 in an orderly manner. After the internal volume of the filter tube 1 is reduced, the amount of air sprayed is also relatively reduced. What originally required 1.2m³ of air volume can now be achieved with only 0.7m³, saving energy and reducing consumption. After the guide liner 14 is added, the airflow enters the inside of the filter tube 1 in an orderly manner, enhancing the surface dust removal effect and extending the service life of the filter cartridge.

[0035] When the filter media cartridge 3 needs to be replaced, the operator can easily rotate the pressure ring 4 through the anti-slip groove 11 to release the pressure ring 4 from the filter media cartridge 3. Then, the old filter media cartridge 3 can be removed from the circumference of the filter tube 1. Next, the new filter media cartridge 3 is placed on the circumference of the filter tube 1. When the first ring 5 contacts the locking block 10, the locking block 10 can restrict the position of the first ring 5, thereby restricting the position of the filter media cartridge 3. Then, the pressure ring 4 is rotated along the circumference of the filter tube 1. The pressure ring 4 will move by means of the thread to further restrict the position of the filter media cartridge 3. At this time, the first sealing ring 7 can improve the sealing between the first ring 5 and the locking ring 2, and the second sealing ring 8 can improve the sealing between the second ring 6 and the pressure ring 4, ensuring that the filter media cartridge 3 can work normally. Therefore, when replacing the filter media cartridge 3, it is not necessary to replace the filter tube 1 together, thereby reducing the cost of use. The support rod 9 can improve the compressive strength of the filter media cartridge 3 and prevent the filter media cartridge 3 from being damaged due to the squeezing of the pressure ring 4.

[0036] During the transport of the filter cartridge, the protective sleeve 12 can shield and protect the filter media cartridge 3, preventing the filter media cartridge 3 from being squeezed and deformed or even broken. At the same time, the inner circumferential surface of the protective sleeve 12 will abut against the circumferential surface of the locking block 10 and the limiting ring 13, thus restricting the position of the protective sleeve 12 and maintaining a certain distance between the protective sleeve 12 and the filter media cartridge 3. When the filter cartridge needs to be used, rotate the pressure ring 4 to remove the pressure ring 4, then remove the protective sleeve 12, and then reinstall the pressure ring 4 to use the filter cartridge normally.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
