Description
Technical Field
[0001] The utility model relates to the technical field of waste gas treatment, in particular to a printing waste gas treatment device. Background Art
[0002] During the offset printing process, a large amount of waste gas is generated. These waste gases have a strong smell. If directly discharged, they will pollute the surrounding air and do not meet the emission standards. Therefore, these waste gases usually need to be treated before being discharged, and these waste gases are usually filtered and adsorbed through activated carbon and filter plates.
[0003] However, the filter plate and activated carbon plate of the existing waste gas treatment device are directly located inside the device housing. Therefore, when it is necessary to disassemble, clean, and replace the filter plate and activated carbon plate, it is necessary to open the housing of the equipment main body, and then disassemble the filter plate and activated carbon plate inside it. During the disassembly and replacement process, the equipment needs to stop running, which is inconvenient to use. For this reason, we propose a printing waste gas treatment device to solve the above problems. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the shortcomings of the existing technology involved in the background art, and to propose a printing waste gas treatment device.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A printing waste gas treatment device includes a waste gas treatment box. An air inlet is provided on one side of the waste gas treatment box, and an air outlet is provided on the other side of the waste gas treatment box. Two groups of filter plates and one group of activated carbon plates are inserted into the top of the waste gas treatment box. Connection plates are provided at the tops of the filter plates and the activated carbon plates, and sealing gaskets are provided around the bottom ends of the connection plates, so that the connection plates are mutually attached to the top of the waste gas treatment box;
[0007] It can make the connection plate drive the filter plate to be inserted into the interior of the waste gas treatment box, so that personnel can directly pull the connection plate externally to complete the disassembly and replacement of the filter plate. At the same time, during the disassembly and replacement of the filter plate, it is not necessary to disassemble the main body of the waste gas treatment box, so that the waste gas treatment box can be used normally.
[0008] Preferably, support frames are provided on both sides of the inner wall of the waste gas treatment box. The support frames are in a U-shaped setting, and both sides of the filter plates and the activated carbon plates are located inside the support frames;
[0009] It can limit both sides of the filter plate, so that the stability of the filter plate after being inserted is better, and avoid the situation that the filter plate shakes and detaches.
[0010] Preferably, sliding slots are formed on both sides of the top end of the waste gas treatment box. A sliding block is arranged inside the sliding slot, and a limiting block is arranged at the top end of the sliding block. The limiting block is located above the end of the connecting plate.
[0011] After the connecting plate is installed at the top end of the waste gas treatment box, the limiting block can slide above the connecting plate to complete the limitation of the connecting plate, avoiding the loosening and detachment of the filter plate caused by the movement of the connecting plate.
[0012] Preferably, a fixed shaft rod is arranged inside the sliding slot, and the sliding block is sleeved outside the fixed shaft rod.
[0013] The limiting block and the sliding block can be limited, so that the sliding stability of the limiting block is better. At the same time, the situation of the limiting block falling off is avoided, so that the limiting block can better complete the limitation of the top end of the connecting plate.
[0014] Preferably, a support spring is sleeved outside the fixed shaft rod. One end of the support spring is fixedly connected with the sliding block, and the other end of the support spring is fixedly connected with the inner wall of the sliding slot. The top edge side of the limiting block is inclined.
[0015] When the connecting plate is installed, the connecting plate squeezes the inclined surface of the limiting block, so that the limiting block moves. Then the support spring drives the sliding block to recover, so that the limiting block moves above the connecting plate again to complete the limitation, making the installation of the connecting plate more convenient.
[0016] Preferably, a rotating threaded rod is inserted into the top end of the limiting block. The bottom end of the rotating threaded rod is movably connected with the top end of the sliding block, and the rotating threaded rod is threadedly connected with the limiting block.
[0017] The height of the limiting block can be adjusted by rotating the rotating threaded rod, so that the limiting block can adapt to the thickness of different connecting plates, making the use effect of the limiting block better.
[0018] Preferably, a movable groove is formed at the bottom end of the limiting block, and the top end of the sliding block extends into the movable groove.
[0019] The sliding block can limit the up and down adjustment of the limiting block, avoiding the rotation between the limiting block and the sliding block, so that the rotation of the rotating threaded rod can better drive the limiting block to adjust the height.
[0020] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0021] 1. The utility model enables the connecting plate to directly drive the filter plate or the activated carbon plate to be embedded into the interior of the waste gas treatment box, and then limits the position through the support frame. The bottom end of the connecting plate is in close contact with the top end of the waste gas treatment box to complete the sealing, so that the personnel can replace the filter plate or the activated carbon plate without opening the whole waste gas treatment box, and the filter plate or the activated carbon plate does not need to stop running during replacement, improving the work efficiency.
[0022] 2. When the connecting plate is installed in the utility model, the limiting block is extruded, so that the limiting block moves along the inclined surface. Then, the support spring drives the limiting block to recover, so that the limiting block moves above the connecting plate to complete the limiting, making the installation of the connecting plate relatively convenient. At the same time, the rotating threaded rod can be rotated to adjust the height of the limiting block, so that the limiting block can adapt to connecting plates of different thicknesses for installation.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0030] Referring to Figures 1-5A printed waste gas treatment device shown in the figure has an air inlet 2 provided on one side of the waste gas treatment box 1, and then an air outlet 3 is provided on the other side of the waste gas treatment box 1. Two groups of filter plates 5 and a group of activated carbon plates 7 are inserted into the top of the waste gas treatment box 1. At the same time, connecting plates 6 are provided at the tops of the filter plates 5 and the activated carbon plates 7. Sealing gaskets are provided around the bottom end of the connecting plate 6, so that the connecting plate 6 fits tightly with the top of the waste gas treatment box 1. Then, support frames 4 are provided on both sides of the inner wall of the waste gas treatment box 1. The support frames 4 are arranged in a U-shape, so that both sides of the filter plates 5 and the activated carbon plates 7 are located inside the support frames 4. At the same time, sliding slots 8 are opened on both sides of the top of the waste gas treatment box 1. Sliding blocks 9 are arranged inside the sliding slots 8. Then, a limiting block 10 is provided at the top of the sliding block 9, and the limiting block 10 is located above the end of the connecting plate 6. At the same time, a fixed shaft rod 11 is arranged inside the sliding slot 8, so that the sliding block 9 is sleeved outside the fixed shaft rod 11.
[0031] Specifically, the limiting block 10 in this embodiment will be described. Please refer to Figure 4 and Figure 5 . A support spring 12 is sleeved outside the fixed shaft rod 11. One end of the support spring 12 is fixedly connected to the sliding block 9, and then the other end of the support spring 12 is fixedly connected to the inner wall of the sliding slot 8. The top side edge of the limiting block 10 is inclined. At the same time, a rotating threaded rod 14 is inserted into the top of the limiting block 10. The bottom end of the rotating threaded rod 14 is movably connected to the top of the sliding block 9, and the rotating threaded rod 14 is threadedly connected to the limiting block 10. Then, a movable slot 13 is opened at the bottom end of the limiting block 10, and the top of the sliding block 9 extends into the movable slot 13.
[0032] Working principle: When in use, when it is necessary to replace the connecting plate 6 and the filter plate 5, the limiting blocks 10 on both sides can be slid so that the limiting blocks 10 are separated from above the connecting plate 6. At this time, the connecting plate 6 can be directly pulled, so that the connecting plate 6 directly drives the filter plate 5 or the activated carbon plate 7 to be separated from the inside of the waste gas treatment box 1, completing the disassembly of the filter plate 5 and the activated carbon plate 7. Then, the replaced filter plate 5 or the activated carbon plate 7 is inserted into the inside of the waste gas treatment box 1 to complete the replacement.
[0033] The filter plate 5 or the activated carbon plate 7 is inserted into the interior of the support frame 4 for limiting. When the connecting plate 6 moves above the waste gas treatment box 1, it is squeezed against the inclined surface of the limiting block 10, causing the limiting block 10 to move along the inclined surface. Subsequently, the support spring 12 drives the limiting block 10 to return to its original position, enabling the limiting block 10 to move above the connecting plate 6 to complete the limitation of the connecting plate 6. At the same time, the rotating threaded rod 14 can be rotated to adjust the height of the limiting block 10, so that the limiting block 10 can better squeeze the top of the connecting plate 6, making the sealing performance of the connecting plate 6 better. Moreover, it can be adjusted according to the connecting plates 6 of different thicknesses, making the use effect of the limiting block 10 better.
