Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to waste gas treatment equipment used in the production of medical-grade carboxyl nitrile latex. Background Art

[0002] Carboxyl nitrile latex is an anionic polymer emulsion. Due to the introduction of strongly polar carboxyl groups on the macromolecular chain, the activity and bonding strength are improved, and the performance is better than that of ordinary nitrile latex. It is generally used as medical grade carboxyl nitrile latex in the production of medical gloves. In the production process of medical grade carboxyl nitrile latex, a lot of waste gas will be generated. In order to increase environmental protection, the waste gas needs to be treated.

[0003] At present, the waste gas treatment of the existing medical grade carboxyl nitrile latex production generally includes spraying method and activated carbon adsorption method. The activated carbon adsorption method uses activated carbon to adsorb harmful substances in the waste gas and treat the waste gas. When using the activated carbon adsorption method to adsorb harmful substances in the waste gas, it is necessary to regularly clean the activated carbon adsorption plate to prevent excessive impurities on the activated carbon adsorption plate from affecting the adsorption effect. When cleaning, the activated carbon adsorption plate needs to be disassembled and assembled. When the activated carbon adsorption plate is disassembled and assembled, it is easy to cause waste gas leakage, so that the waste gas is discharged without being adsorbed by the activated carbon adsorption plate, thereby reducing the effect of waste gas treatment.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the waste gas treatment equipment used for the production of medical-grade carboxyl nitrile latex, when the activated carbon adsorption plate needs to be cleaned or replaced, the activated carbon adsorption plate is first slid out of the processing box. When the activated carbon adsorption plate slides out, it can drive the first lifting rod to move upward, and the first lifting rod moves upward to drive the moving seat to move, and the movement of the moving seat drives the partition to move, and the partition drives the third vent to move, so that the third vent is misaligned with the first vent and the second vent, so that the first vent is blocked, avoiding the situation where a large amount of waste gas leaks when the activated carbon adsorption plate is disassembled and assembled, which is beneficial to improving the waste gas treatment effect.

[0018] 2. In the waste gas treatment equipment for the production of medical-grade carboxyl nitrile latex, when the third vent hole is misaligned with the first vent hole and the second vent hole, the partition drives the airbag to move to the top of the first vent hole, and when the airbag moves to the first vent hole, the piston plate can flush the gas inside the air cavity into the airbag through the air supply groove and the air delivery groove, so that the airbag can expand instantly, so that the airbag can block the first vent hole, thereby increasing the sealing performance at the first vent hole and further preventing the leakage of waste gas;

[0019] 3. In the waste gas treatment equipment used for the production of medical-grade carboxyl nitrile latex, when the activated carbon adsorption plate is installed, the second lifting rod slides in the second slide groove, which can drive the second lifting rod to rise and fall. When the second lifting rod descends, it can drive the connecting plate to move, and the connecting plate drives the piston plate to move, so that a negative pressure state is formed in the air cavity. Therefore, before the partition drives the airbag to reset, the gas inside the airbag can be extracted first, so that the airbag no longer expands. Therefore, when the airbag is reset, it will not rub against the inner wall of the treatment box, thereby reducing the loss of the airbag, which is beneficial to increase the service life of the airbag and prevent the airbag from being worn and having poor sealing.

[0038] A flat plate 21 is fixed to the bottom of the first lifting rod 17, a third spring 22 is fixed between the flat plate 21 and the bottom of the receiving groove 7, a contact platform 23 is fixed inside the moving seat 9, and a contact rod 24 that contacts the contact platform 23 is fixed on the first lifting rod 17;

[0039] A guide groove 25 is provided in the abutment platform 23 for the abutment rod 24 to slide, an abutment protrusion 26 is fixed on the abutment rod 24, and an abutment groove 261 is provided on the inner wall of the guide groove 25 for the abutment protrusion 26 to slide;

[0040] Two groups of activated carbon adsorption plates 3 are arranged in the processing box 1, and the bottom of the processing box 1 is provided with a diversion groove 49 connected with the two groups of activated carbon adsorption plates 3, and the bottom of the processing box 1 is provided with a confluence groove 50 connected with the outlet pipe 6;

[0041] In the present technical solution, when the activated carbon adsorption plate 3 is installed inside the treatment box 1, the first vent hole 4, the second vent hole 5 and the third vent hole 11 are initially connected. When the waste gas is treated, the waste gas to be treated is first introduced into the treatment box 1 through the air inlet pipe 2, and the waste gas enters the activated carbon adsorption plate 3 through the first vent hole 4, the third vent hole 11 and the second vent hole 5. The activated carbon adsorption plate 3 is used to adsorb harmful substances in the waste gas to complete the treatment of the waste gas, and then the treated waste gas is discharged through the outlet pipe 6 for subsequent treatment;

[0042] After the activated carbon adsorption plate 3 has been used for a long time, it is necessary to disassemble, clean or replace the activated carbon adsorption plate 3. When replacing the activated carbon adsorption plate 3, first remove the cover plate 51 on one side of the processing box 1. The cover plate 51 is sealed and connected to the processing box 1 to prevent the activated carbon adsorption plate 3 from leaking from one side of the cover plate 51. The cover plate 51 can be fixed to the processing box 1 by fastening bolts for easy disassembly and assembly. Then, pull the activated carbon adsorption plate 3 out of the processing box 1. In the process of pulling out the activated carbon adsorption plate 3, the first lifting rod 17 moves along the first sliding groove. 15 slides, the first lifting rod 17 drives the first sliding protrusion 18 to slide, when the first sliding protrusion 18 slides from the first rising portion 19 to the first horizontal portion 20, the first sliding protrusion 18 drives the first lifting rod 17 to move upward, the first lifting rod 17 moves upward to drive the abutment rod 24 to move upward along the guide groove 25, the abutment rod 24 drives the abutment protrusion 26 to slide upward, so that the abutment protrusion 26 slides along the abutment groove 261, so that the abutment protrusion 26 abuts against the abutment groove 261, so that the abutment platform 23 moves leftward (such as Figure 5 As shown), the abutment platform 23 moves to the left, driving the moving seat 9 to move to the left, and the moving seat 9 drives the partition 10 to move to the left, and at the same time, the first convex plate 14 drives the first spring 13 to extend and accumulate force (as shown in FIG. Figure 7 As shown), the partition 10 moves to the left, at which time the third vent hole 11 is misaligned with the first vent hole 4 and the second vent hole 5, until the first sliding protrusion 18 slides to the first horizontal portion 20, the third vent hole 11 is completely misaligned with the first vent hole 4 and the second vent hole 5, and the partition 10 is used to block the first vent hole 4 and the second vent hole 5, so that the exhaust gas cannot pass through, and then the activated carbon adsorption plate 3 is continuously pulled, so that the first sliding protrusion 18 slides on the first horizontal portion 20, until the activated carbon adsorption plate 3 is pulled out, and the removal of the activated carbon adsorption plate 3 is completed;

[0043] By setting the No. 3 spring 22, since the initial state of the No. 3 spring 22 is compressed, when the first lifting rod 17 moves upward, the No. 3 spring 22 releases force to assist the first lifting rod 17 to move upward until the first lifting rod 17 slides out of the first sliding groove 15. The No. 3 spring 22 and the first lifting rod 17 maintain balance, so that the position of the first lifting rod 17 will not change due to the sliding of the first sliding protrusion 18 from the first horizontal portion 20, which is convenient for the subsequent installation and reset of the activated carbon adsorption plate 3;

[0044] When installing the activated carbon adsorption plate 3, first push the activated carbon adsorption plate 3 into the processing box 1 to reset the activated carbon adsorption plate 3. During the resetting of the activated carbon adsorption plate 3, the first lifting rod 17 slides into the first sliding groove 15, and the first sliding protrusion 18 slides into the first horizontal portion 20 until the first sliding protrusion 18 slides from the first horizontal portion 20 to the first rising portion 19. At this time, the first sliding protrusion 18 continues to slide downward along the first rising portion 19, driving the first lifting rod 17 to move downward, and at the same time compressing the No. 3 spring 22, so that the No. 3 spring 22 accumulates force. , the first lifting rod 17 moves downward, the resistance rod 24 drives the resistance protrusion 26 to slide downward along the resistance groove 261, and the resistance protrusion 26 pulls the resistance platform 23 to move to the right, so that the partition 10 is reset. At the same time, the No. 1 spring 13 releases force and pulls the partition 10 to move to the right through the first convex plate 14, assisting the partition 10 in resetting, making the partition 10 reset more accurately, until the second vent 5 is connected with the first vent 4 and the second vent 5 again, completing the installation of the activated carbon adsorption plate 3, and then covering the cover plate 51, sealing one side of the activated carbon adsorption plate 3, and performing exhaust gas treatment again.

[0045] In the second embodiment, since the third vent hole 11 is completely misaligned with the first vent hole 4 and the second vent hole 5, there may be leakage from the gap of the partition plate 10 due to insufficient sealing of the partition plate 10, thereby affecting the treatment effect of the exhaust gas. To address this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 12 A piston plate 27 is elastically provided inside the positioning seat 8, an air cavity 28 is provided between the piston plate 27 and the movable seat 9, a groove 29 is provided at the bottom of the air cavity 28, an air supply groove 30 is provided inside the movable seat 9, an air delivery groove 31 connected to the air supply groove 30 is provided inside the partition 10, a receiving groove 32 is provided on the surface of the partition 10, and an air bag 33 connected to the air delivery groove 31 is provided inside the receiving groove 32;

[0046] A No. 4 spring 34 is fixed inside the processing box 1, and the top of the No. 4 spring 34 is fixed on the surface of the piston plate 27;

[0047] In this technical solution, when the activated carbon adsorption plate 3 is moved out, the first lifting rod 17 moves upward, driving the moving seat 9 to move leftward (such as Figure 8As shown in the figure, the moving seat 9 moves to the left, driving the partition 10 to move to the left, and driving the airbag 33 to move to the left at the same time. The airbag 33 is initially contracted in the storage groove 32. When the airbag 33 moves to the left, it will not rub against the inner wall of the processing box 1. When the first sliding protrusion 18 slides from the first rising portion 19 to the first horizontal portion 20, that is, the third vent hole 11 is misaligned with the first vent hole 4 and the second vent hole 5, the airbag 33 moves to the top of the first vent hole 4. In the process of the moving seat 9 moving to the left, the gas inside the air cavity 28 is compressed, pushing the piston plate 27 to move to the left, and compressing the No. 4 spring 34 at the same time. The No. 4 spring 34 accumulates force. When the moving seat 9 continues to move to the left, the gas in the air cavity 28 is compressed, pushing the piston plate 27 to move to the left, and compressing the No. 4 spring 34. The No. 4 spring 34 accumulates force. When the air supply groove 30 moves to the groove 29 (at the same time as the airbag 33 moves to the top of the first vent hole 4), the air cavity 28, the air supply groove 30, the air delivery groove 31 and the airbag 33 are connected, the No. 4 spring 34 releases force, the piston plate 27 moves to the right, and the compressed gas in the air cavity 28 instantly rushes into the airbag 33 through the air supply groove 30 and the air delivery groove 31, so that the airbag 33 expands, and the first vent hole 4 is sealed by the expanded airbag 33 to increase the sealing performance; when the activated carbon adsorption plate 3 is installed, the first lifting rod 17 moves downward, driving the moving seat 9 to move to the right and reset, the moving seat 9 drives the partition 10 to reset, and the partition 10 drives the airbag 33 to reset;

[0048] Embodiment 3: Since the airbag 33 may be in an expanded state when it is reset, the airbag 33 continues to reset, which will cause the expanded airbag 33 to rub against the inside of the processing box 1, thereby causing wear on the surface of the airbag 33, thereby reducing the service life of the airbag 33. To address this problem, this embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 12 A second lifting rod 35 is slidably arranged in the positioning seat 8, a second convex plate 36 is fixed on the second lifting rod 35, a second spring groove 37 is provided on the inner wall of the processing box 1, a second spring 38 is arranged in the second spring groove 37, the second spring 38 is fixed between the second convex plate 36 and the second spring groove 37, a connecting rod 39 is fixed on the piston plate 27, a first abutment block 40 is fixed on the connecting rod 39, a second abutment block 41 abutting against the first abutment block 40 is fixed on the second lifting rod 35, a second slide groove 42 is provided on the lower surface of the activated carbon adsorption plate 3, and the end of the second lifting rod 35 is slidably arranged in the second slide groove 42;

[0049] A second sliding protrusion 43 is fixed to the end of the second lifting rod 35. A second horizontal portion 44, a descending portion 45, a third horizontal portion 46 and a second ascending portion 47 for the second sliding protrusion 43 to slide are provided on the inner wall of the second sliding groove 42. A rotating plate 48 is elastically provided in the second horizontal portion 44.

[0050] In the present technical solution, when the activated carbon adsorption plate 3 is disassembled, the second lifting rod 35 slides rightward in the second sliding groove 42 (such as Fig.12 As shown in the figure, the second lifting rod 35 drives the second sliding protrusion 43 to slide rightward on the second horizontal part 44. First, when the second sliding protrusion 43 slides to the top of the second rising part 47, due to the action of the second spring 38, the second lifting rod 35 and the second spring 38 maintain a balanced state, so that the second sliding protrusion 43 will only slide to the right along the second horizontal part 44, and will not slide downward along the second rising part 47. When the second sliding protrusion 43 slides to the rotating plate 48, it will drive the rotating plate 48 to rotate downward. The rotating plate 48 is elastically connected to the inner wall of the second slide groove 42 through the torsion spring. When the second sliding protrusion 43 slides over the rotating plate 48, the rotating plate 48 can be reset through the torsion spring, and then the second sliding protrusion 43 slides out from the right end of the second horizontal part 44, and the activated carbon adsorption plate 3 is taken out; when the activated carbon adsorption plate 3 is installed, the second sliding protrusion 43 slides to the left along the second horizontal part 44. Since the rotating plate 48 can only be pressed as shown in the figure Fig.12 The state shown in the figure rotates downward and cannot rotate upward. When sliding to the rotating plate 48, the second sliding protrusion 43 will slide downward along the descending portion 45 due to the resistance of the rotating plate 48. At this time, the second sliding protrusion 43 drives the second lifting rod 35 to move downward (at this time, the first sliding protrusion 18 has not slid to the first rising portion 19). The second lifting rod 35 moves downward and drives the second protruding plate 36 to move downward, so that the second spring 38 is compressed and stored. The second lifting rod 35 moves downward and drives the second contact block 41 to move downward, so that the second contact block 41 contacts the first contact block 40 to move, and the first contact block 40 drives the connecting rod 39 to move left (as shown in FIG. Fig. 9 As shown in the figure, the connecting rod 39 drives the piston plate 27 to move leftward, and at the same time compresses the No. 4 spring 34, so that the No. 4 spring 34 accumulates force, and the piston plate 27 moves leftward to form a negative pressure state in the air chamber 28, so that the air chamber 28 extracts the gas inside the air bag 33 through the air supply groove 30 and the air delivery groove 31, so that the air bag 33 becomes deflated and is stored in the storage groove 32, and then the second sliding protrusion 43 slides along the third horizontal portion 46. In this process, the moving seat 9 drives the partition 10 to reset, so that the air bag 33 does not rub against the inner wall of the processing box 1, thereby avoiding the wear of the air bag 33;

[0051] After the airbag 33 is reset, the groove 29 is misaligned with the air supply groove 30, and the air cavity 28 will no longer inhale gas. Then the second sliding protrusion 43 slides along the second rising portion 47, and the second spring 38 releases force, so that the second lifting rod 35 moves upward and resets. The second lifting rod 35 moves upward to drive the second resistance block 41 to move upward, and the first resistance block 40 loses the resistance of the second resistance block 41. The fourth spring 34 releases force, so that the connecting rod 39 moves rightward, driving the piston plate 27 to move rightward (such as Fig. 9 As shown), the negative pressure state of the air cavity 28 is released.

[0052] Embodiment 4: This embodiment is an improvement made on the basis of Embodiment 3. For details, please refer to Figure 1-Figure 12 Two groups of activated carbon adsorption plates 3 are provided in the processing box 1, the bottom of the processing box 1 is provided with a diversion groove 49 connected with the two groups of activated carbon adsorption plates 3, and the top of the processing box 1 is provided with a confluence groove 50 connected with the outlet pipe 6;

[0053] In the present technical solution, two groups of activated carbon adsorption plates 3 are arranged on both sides of the treatment box 1, and the waste gas is respectively directed to the two groups of activated carbon adsorption plates 3 for treatment using the diversion groove 49, and then discharged from the exhaust pipe 6 using the confluence groove 50. When the activated carbon adsorption plates 3 need to be cleaned or replaced, only one group of activated carbon adsorption plates 3 needs to be disassembled first, while the other group of activated carbon adsorption plates 3 can continue to perform the waste gas treatment work, thereby completing the disassembly and assembly of the activated carbon adsorption plates 3 without stopping the waste gas treatment work, thereby increasing the work efficiency.
