Description

Technical Field

[0001] This utility model relates to the field of filter assembly installation technology, and in particular to a drawer-type quick replacement device for filter assemblies in dust removal rooms. Background Technology

[0002] The filter components of a dust collection chamber are the core components of a dust collection system. Their core function is to efficiently capture and remove solid particulate pollutants from the airflow, thereby purifying the air, protecting downstream equipment from wear, ensuring emissions meet standards, and safeguarding the cleanliness of the indoor working environment and the health and safety of personnel. They are typically composed of multiple layers of filter media with different precision. Through physical mechanisms such as interception, inertial collision, diffusion, and electrostatic adsorption, they separate particles of different sizes from the airflow. They are the key execution unit for achieving the efficient dust collection function of a dust collection chamber.

[0003] In traditional methods, when the filter needs to be replaced, the operator has to manually separate the filter from the machine, which is cumbersome and reduces the efficiency of disassembly and replacement. Traditional structures also lack cleaning measures for dust prevention in the slide, which causes dust to accumulate inside, hindering sliding and increasing the risk of failure.

[0004] Therefore, in response to the problems of cumbersome replacement and dust accumulation inside the chute, a drawer-type quick replacement device for dust removal chamber filter components is needed to solve the above problems. Utility Model Content

[0005] To address the problems of cumbersome filter replacement and dust accumulation inside the slide groove in existing technologies, this application provides a drawer-type quick-change device for dust collector filter components. By pulling the mounting rod at the front end of the mounting box outward, the mounting box and mounting bracket move outward as a whole along the first slide groove of the filter housing. When it reaches the fixed block position, the fixed block presses against the second locking block pushed by the second spring, separating the two and allowing the mounting box to continue sliding out. Simultaneously, the first locking block, which is engaged in the second slide groove of the mounting bracket, automatically pops out under the action of the first spring, facilitating the removal of the filter for replacement. During this process, the movement of the mounting bracket causes a brush to automatically clean the dust from the first slide groove, with the dust falling into the dust collection box in the first groove behind it. This achieves quick filter replacement, reduces the impact of dust accumulation in the slide groove on sliding, and improves maintenance efficiency and equipment reliability.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A drawer-type quick-change device for filter components in a dust collector includes a filter housing. The front end of the filter housing has an installation port. The interior of the filter housing has a first sliding groove that communicates with the installation port. An installation bracket is slidably connected inside the first sliding groove. A slide rail is provided on the inner surface of the installation bracket. A replacement component is slidably connected to the outer wall of the slide rail. A first groove is provided on the rear side of the filter housing, and the top of the first groove communicates with the rear side of the first sliding groove.

[0008] As a further improvement of this utility model, the replacement component includes a mounting box that is slidably connected to the outer wall of the slide rail. The inner outer wall of the mounting box has four symmetrical second slide grooves. A slider is slidably connected inside the second slide groove. An installation block is fixedly connected to the outer wall of the slider. A filter is installed inside the installation block.

[0009] As a further improvement of this utility model, a first locking block is slidably connected inside the second slide groove, and a first spring is fixedly connected to the bottom of the first locking block. The first locking block is positioned above the slider.

[0010] As a further improvement of this utility model, a second groove is provided inside one side of the mounting box, a second locking block is slidably connected inside the second groove, a limit block is provided on one side of the second locking block, a second spring is fixedly connected to the outer wall of the second locking block, and one end of the second spring is fixedly connected to the inner wall of the mounting box.

[0011] As a further improvement of this utility model, a brush is installed on the rear bottom of the first chute.

[0012] As a further improvement of this utility model, a dust storage box is slidably connected inside the first groove.

[0013] As a further improvement of this utility model, a fixing block is fixedly connected to the front end of the first chute.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. In this utility model, by pulling the mounting rod at the front end of the mounting box outward, the mounting box and mounting bracket move outward as a whole. When they move to the position of the fixed block, the fixed block presses against the second locking block pushed by the second spring, causing the mounting box to separate from the mounting bracket. At this time, the mounting box can continue to slide out. Subsequently, the first locking block, which is engaged with the second sliding groove on the mounting bracket, automatically pops out under the elastic force of the first spring, allowing the operator to easily remove the filter from the mounting block for replacement. This achieves rapid filter replacement and improves maintenance efficiency.

[0016] 2. In this invention, when the mounting bracket slides along the first groove on the filter housing, the brush moves accordingly, automatically cleaning the dust on the surface of the first groove. The cleaned dust falls into the dust collection box located in the first recess behind the first groove. This reduces dust accumulation in the groove, minimizes the impact of dust on the smooth sliding of the mounting bracket, and improves the reliability of equipment operation.

[0030] Example 1:

[0031] according to Figures 1 to 5 A dust collector filter assembly drawer-type quick replacement device includes a filter housing 1. The front end of the filter housing 1 has an installation port 19. The interior of the filter housing 1 has a first sliding groove 7, which is connected to the installation port 19. An installation bracket 6 is slidably connected inside the first sliding groove 7. A slide rail 18 is provided on the inner surface of the installation bracket 6. A replacement assembly is slidably connected to the outer wall of the slide rail 18. A first groove 2 is provided on the rear side of the filter housing 1. The top of the first groove 2 is connected to the rear side of the first sliding groove 7. A brush 9 is installed at the bottom of the rear side of the first sliding groove 7. A dust collection box 3 is slidably connected inside the first groove 2. A fixing block 8 is fixedly connected to the front end of the first sliding groove 7.

[0032] Specifically, during operation, pulling the mounting box 4 outwards moves the mounting bracket 6 forward along the first slide groove 7. When it reaches the position of the fixing block 8, the fixing block 8 presses against the second locking block 15, separating it from the mounting bracket 6, and the mounting box 4 continues to slide out. At this time, the first locking block 10 automatically pops out under the elastic force of the first spring 13, allowing for quick removal and replacement of the filter 5 on the mounting block 11. Simultaneously, the moving linkage brush 9 of the mounting bracket 6 cleans the accumulated dust in the first slide groove 7, and as it is pushed inwards, the dust falls into the dust collection box 3 in the first groove 2. This achieves quick removal and installation of the filter 5, and simultaneously cleans the accumulated dust in the slide groove, improving maintenance efficiency and equipment reliability.

[0033] Example 2:

[0034] according to Figure 2 , Figure 4 and Figure 5 The outer wall of the slide rail 18 is slidably connected to the mounting box 4. The inner outer wall of the mounting box 4 has four symmetrical second slide grooves 14. The slide rail 12 is slidably connected inside the second slide groove 14. The outer wall of the slide rail 12 is fixedly connected to the mounting block 11. The mounting block 11 has a filter 5 installed inside. The inner wall of the second slide groove 14 is slidably connected to the first locking block 10. The bottom of the first locking block 10 is fixedly connected to the first spring 13. The first locking block 10 is located above the slide rail 12. The inner side of the mounting box 4 has a second groove 17. The inner side of the second groove 17 is slidably connected to the second locking block 15. The side of the second locking block 15 is provided with a limit block. The outer wall of the second locking block 15 is fixedly connected to the second spring 16. One end of the second spring 16 is fixedly connected to the inner wall of the mounting box 4. The first locking block 10 is set to fix the slide rail 12 inside and to prevent too much dust from entering the inner wall of the second slide groove 14.

[0035] Specifically, the mounting box 4 is slidably mounted on the mounting bracket 6 via the slide rail 18. Four second slide grooves 14 are symmetrically arranged inside the box. The slider 12 slides along the second slide grooves 14 and fixes the mounting block 11, with the filter 5 embedded within the mounting block 11. Under normal conditions, the first locking block 10 is pressed down by the first spring 13 to lock the slider 12, fixing the position of the filter 5. The second locking block 15 extends out of the side wall of the mounting box 4 under the action of the second spring 16, engaging with the mounting bracket 6. During replacement, pulling the mounting box 4 out causes the second locking block 15 to be squeezed and retracted by the fixing block 8, unlocking it. After the mounting box 4 slides out, the first locking block 10 automatically springs up to release the slider 12, allowing for quick installation and removal of the filter 5.

[0036] Working Principle: During maintenance, the operator pulls the mounting box 4 outward, causing the mounting bracket 6, which is slidably connected to it, to move forward along the first slide groove 7 inside the filter housing 1. When the mounting bracket 6 moves to the position of the fixing block 8 at the front end of the first slide groove 7, the fixing block 8 presses against the second locking block 15 on the side of the mounting box 4, causing it to retract into the second groove 17 against the elastic force of the second spring 16, thereby releasing the locking state between the mounting box 4 and the mounting bracket 6; the mounting box 4 can then continue to slide out. During this process, the forward movement of the mounting bracket 6 is linked to the brush 9 at its bottom to clean the dust accumulated in the first slide groove 7. After the mounting box 4 has completely slid out, the first locking block 10 above the second slide groove 14 inside it automatically springs upward under the elastic force of the first spring 13, releasing the lock on the slider 12; at this time, the slider 12 can be slid along the second slide groove 14, and together with the mounting block 11 fixed to its outer wall and the internal filter 5, it can be quickly disassembled and replaced. After replacement, the components can be pushed back to their original positions by reversing the operation, enabling quick disassembly and assembly of filter 5 and simultaneous cleaning of dust accumulation in the chute.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
