Description

An easy-to-replace exhaust gas treatment device Technical Field

[0001] This utility model relates to the technical field of waste gas treatment devices, and in particular to a waste gas treatment device that is easy to replace. Background Technology

[0002] In some industrial production processes, it is often necessary to use waste gas treatment devices to filter the waste gas generated in the production process.

[0003] Many traditional exhaust gas treatment devices are directly installed on production equipment. During later maintenance, staff need to disassemble the entire device, including disassembling the connectors, brackets and other components, before the filter mechanism can be removed and replaced. The whole process is time-consuming and labor-intensive, affecting maintenance efficiency. Therefore, an exhaust gas treatment device that is easy to replace is needed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a replaceable waste gas treatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easily replaceable exhaust gas treatment device includes a treatment box. A sliding seat is installed on the inner bottom wall of the treatment box. A sliding plate is slidably installed on the sliding seat. A bottom plate is slidably installed on the sliding plate. A flip plate is rotatably installed on the upper side of the bottom plate. The flip plate and the bottom plate are connected to form a frame for installing an exhaust gas filter element assembly.

[0007] A plug is installed on one side of the bottom of the flip plate. When the flip plate is connected to the base plate, the plug is inserted into the L-shaped slot opened at the top of the base plate. The bottom side of the plug is fastened to the inside of the L-shaped slot by a locking block.

[0008] Below the lock block is a finger block, which is connected to the grip bar. When the grip bar rotates, the finger block deflects and presses against the outer wall of the lock block, causing the lock block to move horizontally under pressure.

[0009] In addition, a preferred structure is that the processing box has an air inlet on one side and an air outlet on the other side, with the air inlet and air outlet connected to the interior of the processing box.

[0010] In addition, in a preferred configuration, the bottom of the sliding plate is connected to a sliding groove on both sides of the sliding seat for a limiting connection, and a limiting strip is provided on one side of the middle part of the sliding seat, so that the sliding plate can move horizontally through the sliding groove.

[0011] In addition, a preferred structure is that the upper part of the sliding plate is provided with a pair of sliding grooves, and a limiting block is installed in the sliding grooves. The limiting block is connected to the bottom wall of the base plate, and the base plate can move horizontally through the sliding grooves.

[0012] In addition, a preferred structure is that the upper side of the base plate is rotatably connected to the flipping plate, and a second torsion spring is provided at the rotatable connection between the base plate and the flipping plate. When the flipping plate rotates, the second torsion spring undergoes torsional deformation.

[0013] In addition, a preferred structure is that a grip bar is rotatably mounted on the outer side of the base plate, one end of the grip bar extends into an L-shaped slot and is connected to a finger block, and a torsion spring is installed at the rotatable connection between the grip bar and the base plate. When the grip bar rotates, the torsion spring deforms to the torsion.

[0014] In addition, a preferred structure is that a slot is provided on one side of the bottom of the insert block to install the locking block. The locking block is slidably installed in the slot, and the locking block and the slot are connected by a spring. When the locking block moves horizontally, the spring deforms.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this utility model, a frame structure is formed by a flip plate and a base plate to install the exhaust gas filter element assembly. The flip plate and the base plate are quickly connected by a slot for inserting blocks. Pressing down the lever can push the locking block on the insert block, causing the locking block to disengage from the slot for quick unlocking. Furthermore, the sliding seat and the limiting plate enable the movement of the exhaust gas filter element assembly, thereby achieving the function of quick replacement of the exhaust gas filter element assembly and improving maintenance efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Referring to Figures 1-9, an easy-to-replace exhaust gas treatment device includes a treatment box 1. A sliding seat 6 is installed on the inner bottom wall of the treatment box 1. A sliding plate 7 is slidably installed on the sliding seat 6. A bottom plate 3 is slidably installed on the sliding plate 7. A flip plate 31 is rotatably installed on the upper side of the bottom plate 3. The flip plate 31 and the bottom plate 3 are connected to form a frame for installing the exhaust gas filter element assembly 4.

[0029] Furthermore, a plug 33 is installed on one side of the bottom of the flip plate 31. When the flip plate 31 is connected to the base plate 3, the plug 33 is inserted into the L-shaped slot 10 opened at the top of the base plate 3. The bottom side of the plug 33 is fastened to the inside side of the L-shaped slot 10 by the locking block 34.

[0030] Furthermore, a finger block 52 is provided below the locking block 34. The finger block 52 is connected to the grip bar 5. When the grip bar 5 rotates, the finger block 52 deflects and presses against the outer wall of the locking block 34, and the locking block 34 is compressed to achieve horizontal displacement.

[0031] The processing box 1 has an air inlet 11 on one side and an air outlet 12 on the other side. The air inlet 11 and the air outlet 12 are connected to the interior of the processing box 1.

[0032] The bottom of the sliding plate 7 is limited and connected to the sliding grooves 61 on both sides of the sliding seat 6. A limiting strip 62 is provided on one side of the middle part of the sliding seat 6. The sliding plate 7 moves horizontally through the sliding grooves 61. A downward protrusion is provided on one side of the sliding plate 7. When the sliding plate 7 moves outward, the protrusion contacts the limiting strip 62, and the limiting strip 62 blocks the sliding plate 7, preventing it from moving further, so as to ensure that the sliding plate 7 slides stably and smoothly on the sliding seat 6.

[0033] A pair of sliding grooves 71 are provided on the upper part of the sliding plate 7. A limiting block 32 is installed in the sliding groove 71 and is connected to the bottom wall of the base plate 3. The base plate 3 can move horizontally through the sliding groove 71.

[0034] The upper side of the base plate 3 is rotatably connected to the flip plate 31, and a torsion spring 8 is provided at the rotatable connection between the base plate 3 and the flip plate 31. When the flip plate 31 rotates, the torsion spring 8 is torsional and deformed, and the torsional force causes the flip plate 31 to rotate in the opposite direction to reset after rotation.

[0035] A grip 5 is rotatably mounted on the outer side of the base plate 3. One end of the grip 5 extends into the L-shaped slot 10 and is connected to a finger block 52. A torsion spring 51 is installed at the rotatable connection between the grip 5 and the base plate 3. When the grip 5 rotates, the torsion spring 51 torsional deformation causes the grip 5 to rotate back to its original position.

[0036] A slot is provided on one side of the bottom of the insert block 33 to install the locking block 34. The locking block 34 is slidably installed in the slot. The locking block 34 is connected to the slot by a spring 35. When the locking block 34 moves horizontally, the spring 35 deforms.

[0037] A sealed door 2 is installed on the outside of the processing box 1 to ensure the normal operation of the device.

[0038] In this embodiment, when replacing the exhaust gas filter element assembly 4 inside the processing box 1, the exhaust gas filter element assembly 4 is pulled out by opening the sealed box door 2 and holding the handle 5. At the same time, the handle 5 is pulled down to drive the finger block 52 to deflect upward, thereby squeezing the locking block 34 at the bottom of the flip plate 31. This causes the locking block 34 to move inward to disengage from the inner wall of the L-shaped slot 10. At this time, under the torsional force of the second torsion spring 8, the flip plate 31 is automatically opened and the exhaust gas filter element assembly 4 is exposed, which can then be replaced by the operator.

[0039] During the installation of the exhaust gas filter element assembly 4, the exhaust gas filter element assembly 4 is placed on the base plate 3 and the flip plate 31 is snapped off. The flip plate 31 and the inner and outer sides of the base plate 3 are both provided with limit plates 9 to limit the outer edge of the exhaust gas filter element assembly 4 and ensure its installation stability.

[0040] At the same time, the insert block 33 at the bottom of the flip plate 31 is inserted into the L-shaped slot 10 opened on the upper part of the base plate 3. During this process, the bottom wall of the locking block 34 is squeezed and displaced, thus entering the L-shaped slot 10. The L-shaped slot design allows the inner corner of the slot to engage with the locking block 34. At this time, the locking block 34 and the L-shaped slot 10 are docked, and the base plate 3 and the flip plate 31 are docked.

[0041] Then, the flip plate 31 is pushed so that the exhaust gas filter element assembly 4 re-enters the treatment box 1.

[0042] The sliding plate 7 has a second sliding groove 71 to allow the base plate 3 to move. When the base plate 3 moves outward until the limiting block 32 contacts the outermost edge of the second sliding groove 71, the base plate 3 drives the sliding plate 7 to move. This is easy to understand intuitively and will not be explained further.

[0043] The sliding seat 6 has a groove 61 to allow the sliding plate 7 to move. When the sliding plate 7 moves outward until it contacts the limiting strip 62, the sliding plate 7 is blocked by the limiting strip 62 and cannot continue to move outward. This is easy to understand intuitively.

[0044] The upper surface of the locking block 34 is horizontal, and the bottom side is set as a slope.

[0045] The device that generates waste gas is connected to the air inlet 11 of the treatment box 1 so that the waste gas enters the interior of the treatment box 1 and is discharged from the air outlet 12 after filtration.

[0046] The specific connection method and process between the processing box 1 and the connecting device are common knowledge to those skilled in the art and will not be explained further.

[0047] The specific material of the exhaust gas filter element assembly 4 is existing technology, and those skilled in the art have the ability to configure it according to the corresponding exhaust gas properties, so it will not be explained further.

[0048] The sliding connection between the sliding seat, sliding plate, and base plate forms a slide rail-like structure to enable quick extraction and installation of the exhaust gas filter element without additional disassembly. Furthermore, the insertion block and L-shaped slot enable quick docking, ensuring basic snap-fit ​​stability while providing convenience during the docking process.

[0049] Furthermore, in the later stages, it is only necessary to press the lever to drive the finger block 52 to push the locking block on the insert block, so that it disengages from the L-shaped slot to achieve a quick unlocking function.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
