Description

Technical Field

[0001] This utility model relates to the field of explosion-proof dust removal technology, and in particular to a drawer-type explosion-proof dust removal activated carbon adsorption device. Background Technology

[0002] Industries such as coatings and plastics generate a large amount of dust and waste gas during production, which can have a significant impact on the workshop environment. The best way to remove dust and waste gas is through activated carbon adsorption. Many factories use tower-shaped tank-type adsorption equipment, where the activated carbon adsorption layer is randomly piled up inside the tank. Waste gas enters the activated carbon adsorption tank from the bottom of the tower and moves towards the top. After being purified by the activated carbon adsorption layer, the clean gas is discharged from the top of the tower.

[0003] Currently, existing drawer-type explosion-proof dust removal activated carbon adsorption devices require the removal of multiple mounting bolts on the internal activated carbon components after long-term use, making the disassembly and assembly process cumbersome. Secondly, when replacing activated carbon, only the entire component containing the activated carbon can be replaced, increasing the cost of activated carbon replacement. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drawer-type explosion-proof activated carbon adsorption device for dust removal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drawer-type explosion-proof dust removal activated carbon adsorption device, comprising a shell, the bottom wall of which has multiple openings, and each opening has a frame plate running through it. A bottom plate is fixed to the bottom end of the frame plate, the upper surface of the bottom plate is attached to the lower surface of the shell, the two sides of the frame plate are attached to the inner sidewall of the shell, a detachable top cover is fixed to the top of the frame plate, the two sides of the frame plate are hollowed out, and a mesh is fixed to the hollowed-out positions on both sides of the frame plate. Activated carbon is filled inside the frame plate, and snap-fit ​​components are provided on both sides of the bottom end of the frame plate. A snap-fit ​​hole for snapping into the snap-fit ​​component is provided on the bottom sidewall of the shell near the snap-fit ​​component, and a handle is fixed to the lower surface of the bottom plate. A pull plate is provided inside the handle, and steel wires for pulling the snap-fit ​​component are fixed to both ends of the pull plate. The frame plate, top cover, mesh, and activated carbon constitute an adsorption component.

[0006] Furthermore, the upper surface of the top cover is fitted to the inner top wall of the housing, and insert plates are fixed on both sides of the lower surface of the top cover. Slots for inserting the insert plates are opened on both sides of the top of the frame plate. A threaded hole is opened on the side of the slot near the surface of the frame plate, and a bolt is rotatably connected inside the threaded hole.

[0007] Furthermore, a countersunk hole is provided on the surface of the frame plate near the threaded hole, and the nut of the bolt is located inside the countersunk hole.

[0008] Furthermore, the snap-fit ​​assembly includes a groove formed on the side wall of the frame plate, a spring is fixed to the inner side wall of the groove, and a snap-fit ​​rod is fixedly connected to the other end of the spring, with the end of the snap-fit ​​rod away from the spring snapping into the snap-fit ​​hole.

[0009] Furthermore, two guide rods are fixed inside the handle. The two guide rods pass through the pull plate and are slidably connected to the pull plate. A second side hole is opened on both sides of the handle, and a first side hole is opened at the bottom of the groove.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-6 As shown, a drawer-type explosion-proof dust removal activated carbon adsorption device is disclosed, comprising a housing 1, with multiple openings 101 on the bottom wall of the housing 1, and a frame plate 2 penetrating through each opening 101. A bottom plate 3 is fixed to the bottom end of the frame plate 2, and the upper surface of the bottom plate 3 is attached to the lower surface of the housing 1. The two sides of the frame plate 2 are attached to the inner sidewalls of the housing 1. A detachable top cover 4 is fixed to the top of the frame plate 2. The two sides of the frame plate 2 are hollowed out, and a mesh 5 is fixed to the hollowed-out positions on both sides of the frame plate 2. Activated carbon is filled inside the frame plate 2. A snap-fit ​​component 6 is provided on both sides of the bottom end of the frame plate 2. A snap-fit ​​hole 25 for snapping into the snap-fit ​​component 6 is provided on the bottom sidewall of the housing 1 near the snap-fit ​​component 6. A handle 7 is fixed to the lower surface of the bottom plate 3. A pull plate 8 is provided inside the handle 7, and steel wires 9 for pulling the snap-fit ​​component 6 are fixed to both ends of the pull plate 8. The frame plate 2, the top cover 4, the mesh 5, and the activated carbon constitute an adsorption component.

[0025] Side tubes are fixed on both sides of the casing 1.

[0026] In this embodiment, the two side pipes are the air inlet pipe and the air outlet pipe, respectively. The exhaust gas enters the housing 1 through the air inlet pipe, is filtered by the adsorption assembly, and is discharged through the air outlet pipe.

[0027] The upper surface of the top cover 4 is attached to the inner top wall of the housing 1. Insert plates 41 are fixed on both sides of the lower surface of the top cover 4. Slots 21 for inserting the insert plates 41 are opened on both sides of the top of the frame plate 2. A threaded hole 22 is opened on the side of the slot 21 near the surface of the frame plate 2. A bolt 23 is rotatably connected inside the threaded hole 22.

[0028] In this embodiment, bolt 23 is an internal hex bolt. When installing the top cover 4, insert the insert plates 41 on both sides of the bottom end of the top cover 4 into the corresponding slots 21 on the top of the frame plate 2, and then screw the bolt 23 into the threaded hole 22. The bolt 23 is used to press and fix the insert plates 41. When replacing the activated carbon inside the frame plate 2, first unscrew the bolt 23, remove the top cover 4 from the top of the frame plate 2, pour out the activated carbon inside the frame plate 2, refill with activated carbon, and then install the top cover 4.

[0029] A countersunk hole 24 is provided on the surface of the frame plate 2 near the threaded hole 22, and the nut of the bolt 23 is located inside the countersunk hole 24.

[0030] By setting countersunk holes 24, the nuts of bolts 23 are located inside the countersunk holes 24, ensuring that the two sides of the frame plate 2 are flat, so that the frame plate 2 can be inserted into the housing 1 and fit against the inner wall of the housing 1.

[0031] The snap-fit ​​assembly 6 includes a groove 61 formed on the side wall of the frame plate 2. A spring 62 is fixed to the inner side wall of the groove 61, and a snap-fit ​​rod 63 is fixedly connected to the other end of the spring 62. The end of the snap-fit ​​rod 63 away from the spring 62 is snapped into the snap-fit ​​hole 25.

[0032] When the frame plate 2 passes through the opening 101 and is inserted into the housing 1, and the bottom plate 3 is in contact with the lower surface of the housing 1, the locking rod 63 is aligned with the locking hole 25, and the spring 62 will squeeze the locking rod 63 into the locking hole 25, thereby fixing the frame plate 2 inside the housing 1.

[0033] Two guide rods 10 are fixed inside the handle 7. The two guide rods 10 pass through the pull plate 8 and are slidably connected to the pull plate 8. A second side hole 71 is opened on both sides of the handle 7. A first side hole 31 is opened at the bottom of the groove 61. The end of the steel wire 9 away from the pull plate 8 passes through the second side hole 71 and the first side hole 31 on the corresponding side in sequence and is fixedly connected to the clamping rod 63.

[0034] When it is necessary to remove the frame plate 2 from the housing 1, hold the handle 7 and pull the pull plate 8. Use the steel wire 9 to pull the locking rod 63 into the groove 61. The locking rod 63 will then separate from the locking hole 25, and the frame plate 2 can be pulled out from the bottom opening 101 of the housing 1. When reinstalling the frame plate 2, first hold the handle 7 and then pull the pull plate 8, keeping the locking rod 63 in the groove 61. Then insert the frame plate 2 into the housing 1 through the opening 101. Next, release the pull plate 8. The spring 62 will push the locking rod 63 into the corresponding locking hole 25, thus fixing the frame plate 2 in place.

[0035] Working principle: Exhaust gas enters the interior of housing 1 through the inlet pipe on one side of housing 1, and is discharged through the outlet pipe on the other side of housing 1 after being adsorbed and filtered by the activated carbon of multiple adsorption components. When it is necessary to replace the activated carbon of the adsorption components, hold the handle 7 and pull the pull plate 8. Use the steel wire 9 to pull the locking rod 63 into the groove 61. After the locking rod 63 separates from the locking hole 25, pull the frame plate 2 out from the bottom opening 101 of housing 1, then remove the top cover 4 of the frame plate 2, pour out the activated carbon inside the frame plate 2 and add new activated carbon. Then reverse the operation to install.
