Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, specifically to a nozzle for a bag filter. Background Technology

[0002] A bag filter is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When dust-laden gas enters the bag filter, larger and heavier dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is trapped, thus purifying the gas.

[0003] Currently, some nozzles used in baghouse dust collectors on the market have dust filtration devices installed inside. Since the filter screen is mostly fixed inside the nozzle, it is difficult to quickly disassemble and clean it when it becomes clogged. If the filter screen continues to become clogged, it will directly lead to a decrease in the dust removal effect of the dust collector, which is not conducive to its use. To address this, we have proposed a nozzle for baghouse dust collectors to solve the problems mentioned in the background technology. Utility Model Content

[0004] The purpose of this invention is to provide a nozzle for a bag filter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nozzle for a bag filter, comprising a filter tube and a nozzle body, wherein the filter tube and the nozzle body are threadedly connected, and a support plate is fixedly connected to the inner wall of the nozzle body by two crossbars, and a column is fixedly installed on the top of the support plate, wherein an insertion post is integrally formed at the top of the column, and two locking blocks that can move laterally are symmetrically arranged on the insertion post, and two filter screen bodies are also sleeved on the insertion post, wherein the two locking blocks located on the same side above and below are respectively inserted into the two filter screen bodies.

[0006] Furthermore, the interior of the upright and the plug-in post is connected to form a storage cavity, and two translation frames are slidably connected in the storage cavity along the lateral direction. The locking block is fixedly connected to the outside of the translation frames.

[0007] Furthermore, a guide crossbar is fixedly connected between the left and right sides of the inner wall of the storage cavity, and the translation frame is slidably connected to the surface of the guide crossbar along the axial direction. A thrust spring is sleeved on the surface of the guide crossbar and located between the two translation frames. A pressing block is also fixedly connected to the outside of the translation frame, and one side of the pressing block extends through to the outside of the column.

[0008] Furthermore, positioning rods are symmetrically installed at the top of the column, and the filter screen body frame has through holes that are adapted to the positioning rods at the corresponding positions.

[0009] Furthermore, the filter body has locking holes adapted to the locking block on its mesh frame, and the two filter bodies have different filter hole diameters.

[0010] Furthermore, the inner surface of the bottom end of the filter tube is provided with an internal thread, and the outer surface of the top end of the nozzle body is provided with an external thread that matches the internal thread.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model features two filter screens with different apertures snapped into the inside of the filter tube, enabling stratified dust filtration. When blockage occurs, the nozzle body can be unscrewed from the filter tube. Pressing the two pressing blocks inward causes the two translation brackets to move inward on the guide crossbar, causing the locking block to retract to the inside of the insertion post and disengage from the locking hole. At this point, the two filter screens can be removed for cleaning or replacement, improving practicality. This bag filter nozzle has a reasonable structural design and is easy to use. It uses a snap-fit ​​method to fix the internal filter screens, allowing for quick disassembly, cleaning, or replacement when blockage occurs, thus ensuring the dust removal effect of the dust collector and facilitating the use of bag filters.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 A nozzle for a bag filter includes a filter tube 1 and a nozzle body 2. The filter tube 1 and the nozzle body 2 are threaded together. A support plate 3 is fixedly connected to the inner wall of the nozzle body 2 by two crossbars. A column 4 is fixedly installed on the top of the support plate 3. An insertion post 5 is integrally formed at the top of the column 4. Two locking blocks 6 that can move laterally are symmetrically arranged on the insertion post 5. Two filter screen bodies 7 are also sleeved on the insertion post 5. The filter screen body 7 consists of a mesh frame and a filter screen inside it. The mesh frame adopts a ring structure and its outer surface is in contact with the inner wall of the filter tube 1. The two locking blocks 6 located on the same side at the top and bottom are respectively inserted into the two filter screen bodies 7.

[0019] Specifically, the internal connection between the upright post 4 and the plug post 5 is provided with a storage cavity 8. Two sliding frames 9 are slidably connected in the storage cavity 8 along the horizontal direction, and the locking block 6 is fixedly connected to the outside of the sliding frame 9.

[0020] Specifically, a guide crossbar 10 is fixedly connected between the left and right sides of the inner wall of the storage cavity 8. The translation frame 9 is slidably connected to the surface of the guide crossbar 10 along the axial direction. A thrust spring 11 is sleeved on the surface of the guide crossbar 10 and located between the two translation frames 9. The two ends of the thrust spring 11 are fixedly connected to the two translation frames 9 respectively. A pressing block 12 is also fixedly connected to the outside of the translation frame 9. One side of the pressing block 12 extends through to the outside of the column 4.

[0021] Specifically, positioning rods 13 are symmetrically installed at the top of the column 4, and insertion holes 14 that are adapted to the positioning rods 13 are opened on the filter body 7 mesh frame at the corresponding positions.

[0022] Specifically, the filter body 7 has a locking hole 15 on its mesh frame that matches the locking block 6, and is equipped with a positioning rod 13 and an insertion hole 14. This ensures that after the filter body 7 is inserted, the locking hole 15 on the mesh frame is aligned with the locking block 6, thus facilitating positioning and insertion. The two filter bodies 7 have different pore diameters. By setting filter bodies 7 with different pore diameters, the effect of stratified filtration of dust of different volumes can be achieved, thereby achieving a good dust removal effect.

[0023] Specifically, the inner surface of the bottom end of the filter tube 1 is provided with an internal thread, and the outer surface of the top end of the nozzle body 2 is provided with an external thread that matches the internal thread. The threaded connection design allows for the quick removal of the nozzle body 2.

[0024] This baghouse dust collector uses nozzles with a reasonable structural design and is easy to use. It uses a snap-fit ​​method to fix the internal filter screen, which can be quickly disassembled for cleaning or replacement when it becomes clogged, thus ensuring the dust removal effect of the dust collector and facilitating its use.

[0025] In use, two filter bodies 7 with different apertures are snapped into the inside of the filter tube 1, which can achieve layered filtration of dust. When blockage occurs, the nozzle body 2 can be unscrewed from the filter tube 1. After pressing the two pressing blocks 12 inward, the two translation brackets 9 will move inward on the guide crossbar 10, and the locking block 6 will retract to the inside of the insertion post 5, disengaging from the insertion between it and the locking hole 15. At this time, the two filter bodies 7 can be removed for cleaning or replacement, improving practicality.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
