Description
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 for polyurethane screen production. Background Technology
[0002] The waste gas treatment device is used in the production of polyurethane screens to treat pollutants in waste gas. When using the waste gas treatment device, the waste gas is introduced into the main body of the device through the air inlet. The waste gas then passes through the connecting frame, where the pollutants are adsorbed by the activated carbon inside the connecting frame. This effectively treats the waste gas. The treated waste gas is then discharged from the main body of the device through the air outlet pipe by an air pump.
[0003] In their daily work, the inventors discovered that the waste gas treatment device still has at least the following problems: When using the waste gas treatment device, the waste gas is introduced into the main body of the device through the air inlet, and then the waste gas passes through the connecting frame. The pollutants inside the waste gas are adsorbed by the activated carbon set inside the connecting frame, which can effectively treat the waste gas. Then, the treated waste gas is discharged from the main body of the device through the air outlet pipe by the air pump. However, in actual use, prolonged use of activated carbon will reduce the adsorption efficiency, which will affect the treatment efficiency to some extent. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a polyurethane screen production waste gas treatment device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a polyurethane screen production waste gas treatment device, comprising a treatment device body, an air inlet on one side of the treatment device body, an air outlet pipe at the end of the treatment device body away from the air inlet, an air pump on the surface of the air outlet pipe, a connecting frame inside the treatment device body, a connecting device on one side of the treatment device body, a heat dissipation device on the surface of the treatment device body, the connecting device comprising an arc plate, a notch on one side of the treatment device body, a rectangular groove on one side of the notch, a rectangular strip slidably connected to the inner wall of the rectangular groove, the side of the rectangular strip away from the rectangular groove being fixedly connected to the side of the arc plate, a support rod fixedly connected to the bottom of the connecting frame, and a connecting cylinder fixedly connected to the bottom of the inner wall of the treatment device body, the inner wall of the connecting cylinder being slidably connected to the bottom of the support rod.
[0006] The effect achieved by the above components is as follows: when using the connecting device, the support rod is manually slid into the inside of the connecting cylinder, and then the rectangular strip is slid into the inside of the rectangular groove. This allows the connecting frame to be properly set inside the main body of the processing device, thus facilitating the replacement of the activated carbon inside the connecting frame.
[0007] Preferably, a locking groove is provided on one side of the inner wall of the rectangular groove, and a rubber strip is provided on the inner wall of the locking groove. The end of the rubber strip away from the locking groove is fixedly connected to one side of the rectangular strip.
[0008] The effect achieved by the above components is that the rectangular strip is slid into the inside of the rectangular groove, and then the rubber strip is squeezed into the inside of the locking groove. This can effectively set the arc plate at the notch and provide a certain degree of sealing.
[0009] Preferably, a support ring is uniformly fixedly connected to the surface of the main body of the processing device. A first damping rod is fixedly connected to the end of each support ring near the notch. A first spring is sleeved on the surface of the first damping rod. One end of the first spring is fixedly connected to one side of the support ring. The end of the first spring near the first damping rod is fixedly connected to one side of the moving ring. A moving ring is fixedly connected to the end of the first damping rod away from the support ring. A rubber ring is fixedly connected to the moving ring near the interior of the main body of the processing device.
[0010] The effect achieved by the above components is as follows: the first spring presses the moving ring towards the notch, thereby pressing the rubber ring against the connection between the arc plate and the main body of the processing device. This can effectively confine the arc plate inside the notch and provide a certain degree of sealing.
[0011] Preferably, a rectangular plate is uniformly fixedly connected to the bottom of the inner wall of the main body of the processing device. A fixing rod is slidably inserted through one side of the rectangular plate. The fixing rod is slidably inserted through one side of the connecting cylinder. The fixing rod is slidably inserted through one side of the support rod. A second spring is sleeved on the surface of the fixing rod. One end of the second spring is fixedly connected to one end of the fixing rod. The end of the second spring near the fixing rod is fixedly connected to one side of the rectangular plate.
[0012] The effect achieved by the above components is as follows: after the fixing rod passes through the rectangular plate, the fixing rod passes through the connecting cylinder and the support rod. The second spring pulls the fixing rod towards the rectangular plate, thereby effectively confining the fixing rod inside the support rod. This effectively confines the support rod inside the main body of the processing device.
[0013] Preferably, the heat dissipation device includes an iron plate, which is fixedly connected to the inner wall of the main body of the processing device, and the portion of the iron plate inside the main body of the processing device has evenly distributed air vents.
[0014] The effect achieved by the above components is as follows: When using the heat dissipation device, because the polyurethane screen will generate a relatively high temperature during the production process, the resulting exhaust gas will also have a relatively high temperature. When the exhaust gas passes through the iron plate, the heat on the exhaust gas will be exchanged with the outside through the iron plate, which can reduce the temperature of the exhaust gas to a certain extent, thereby preventing the high temperature exhaust gas from affecting the activity of the activated carbon.
[0015] Preferably, the iron plate is uniformly fixedly connected to the inner wall of the main body of the processing device with iron rings away from the iron plate.
[0016] The effect achieved by the above components is that the iron ring can increase the contact area of the iron plate to a certain extent, thereby improving the heat dissipation efficiency of the iron plate to a certain extent.
[0017] Preferably, a connecting box is fitted onto the surface of the main body of the processing device, a connecting pipe is fixedly connected to one side of the connecting box, a water pump is provided on the surface of the connecting pipe, and a water inlet is provided on the top of the connecting box.
[0018] The effect achieved by the above components is that the water pump circulates water inside the connecting box and connecting pipe, which can change the temperature of the main surface of the treatment device to a certain extent, thereby playing a certain role in cooling.
[0019] Preferably, the inner wall of the connecting box is uniformly provided with positioning frames, the positioning frames are connected to the interior of the connecting box, and the positioning frames are located on one side of the iron plate.
[0020] The effect achieved by the above components is that, because the positioning frame is set on one side of the iron plate, the connecting box can be well placed on the surface of the main body of the processing device.
[0021] In this invention, by setting a connecting device, when using the connecting device, the support rod is manually slid into the inside of the connecting cylinder, and then the rectangular strip is slid into the inside of the rectangular groove. This allows the connecting frame to be properly set inside the main body of the processing device, thus facilitating the replacement of the activated carbon inside the connecting frame.

[0027] Example 1, as Figure 1-4 As shown, a polyurethane screen production waste gas treatment device has an air inlet 2 on one side of the main body 1 and an air outlet pipe 3 at the end of the main body 1 away from the air inlet 2. An air pump 4 is installed on the surface of the air outlet pipe 3. A connecting frame 5 is installed inside the main body 1, a connecting device 6 is installed on one side of the main body 1, and a heat dissipation device 7 is installed on the surface of the main body 1. When using the waste gas treatment device, the waste gas is introduced into the interior of the main body 1 through the air inlet 2, and then passes through the connecting frame 5. The pollutants inside the waste gas are adsorbed by the activated carbon installed inside the connecting frame 5, which can effectively treat the waste gas. Then, the treated waste gas is discharged from the interior of the main body 1 through the air outlet pipe 3 by the air pump 4. This effectively treats the waste gas.
[0028] Reference Figure 2 and Figure 3The connecting device 6 includes an arc plate 602. A notch 601 is provided on one side of the processing device body 1, and a rectangular groove 604 is provided on one side of the notch 601. A rectangular strip 603 is slidably connected to the inner wall of the rectangular groove 604. The side of the rectangular strip 603 away from the rectangular groove 604 is fixedly connected to the side of the arc plate 602. A support rod 612 is fixedly connected to the bottom of the connecting frame 5. A connecting cylinder 613 is fixedly connected to the bottom of the inner wall of the processing device body 1. The inner wall of the connecting cylinder 613 is slidably connected to the bottom of the support rod 612. When using the connecting device 6, the support rod 612 is manually slid into the inside of the connecting cylinder 613, and then the rectangular strip 603 is slid into the inside of the rectangular groove 604. This allows the connecting frame 5 to be properly positioned in the processing device body 1. The rectangular groove 604 has a slot 606 on one side of its inner wall. A rubber strip 605 is provided on the inner wall of the slot 606. The end of the rubber strip 605 away from the slot 606 is fixedly connected to one side of the rectangular strip 603. The rectangular strip 603 is slid into the rectangular groove 604, and the rubber strip 605 is pressed into the slot 606. This can effectively position the arc plate 602 at the notch 601 and provide a certain degree of sealing. Support rings 607 are uniformly fixedly connected to the surface of the main body 1 of the processing device. A first damping rod 608 is fixedly connected to the end of the support ring 607 near the notch 601. A first spring 61 is sleeved on the surface of the first damping rod 608. One end of the first spring 610 is fixedly connected to one side of the support ring 607. The end of the first spring 610 near the first damping rod 608 is fixedly connected to one side of the moving ring 609. The end of the first damping rod 608 away from the support ring 607 is fixedly connected to the moving ring 609. A rubber ring 611 is fixedly connected to the moving ring 609 near the interior of the processing device body 1. By pressing the moving ring 609 towards the notch 601 through the first spring 610, the rubber ring 611 is pressed against the connection between the arc plate 602 and the processing device body 1. This can effectively confine the arc plate 602 inside the notch 601 and provide a certain sealing effect. Rectangular plates 6 are uniformly fixedly connected to the bottom of the inner wall of the processing device body 1. 14. A fixing rod 615 is slidably inserted through one side of the rectangular plate 614. The fixing rod 615 is slidably inserted through one side of the connecting cylinder 613 and one side of the support rod 612. A second spring 616 is sleeved on the surface of the fixing rod 615. One end of the second spring 616 is fixedly connected to one end of the fixing rod 615. The end of the second spring 616 near the fixing rod 615 is fixedly connected to one side of the rectangular plate 614. After the fixing rod 615 passes through the rectangular plate 614, it passes through the connecting cylinder 613 and the support rod 612. The second spring 616 pulls the fixing rod 615 towards the rectangular plate 614, thus effectively confining the fixing rod 615 inside the support rod 612.This effectively confines the support rod 612 within the main body 1 of the processing device.
[0029] Reference Figure 4 The heat dissipation device 7 includes an iron plate 701, which is fixedly connected to the inner wall of the main body 1 of the processing device. The iron plate 701 has evenly spaced air vents 702 inside the main body 1. When using the heat dissipation device 7, the high temperature generated during the production of the polyurethane screen results in high-temperature exhaust gas. When the exhaust gas passes through the iron plate 701, the heat on the exhaust gas is exchanged with the outside environment through the iron plate 701, thus reducing the temperature of the exhaust gas to a certain extent and preventing the high-temperature exhaust gas from affecting the activity of the activated carbon. Iron rings 703 are evenly fixedly connected to the iron plate 701 away from the inner wall of the main body 1. The iron rings 703 can increase the contact area of the iron plate 701 to a certain extent, thereby improving the efficiency of the heat dissipation device 701. To improve heat dissipation efficiency, a connecting box 704 is fitted onto the surface of the main body 1 of the processing device. A connecting pipe 705 is fixedly connected to one side of the connecting box 704. A water pump 706 is installed on the surface of the connecting pipe 705. A water inlet 707 is installed on the top of the connecting box 704. The water pump 707 circulates water within the connecting box 704 and the connecting pipe 705, which can change the surface temperature of the main body 1 of the processing device to a certain extent, thereby achieving a certain cooling effect. The inner wall of the connecting box 704 is evenly provided with positioning frames 708, which are connected to the interior of the connecting box 704. The positioning frames 708 are located on one side of the iron plate 701. Because the positioning frames 708 are located on one side of the iron plate 701, the connecting box 704 can be well positioned on the surface of the main body 1 of the processing device.
[0030] Working principle: When using the waste gas treatment device, waste gas is introduced into the main body 1 of the treatment device through the air inlet 2. The waste gas then passes through the connecting frame 5, where pollutants are adsorbed by the activated carbon inside the connecting frame 5. This effectively treats the waste gas. The treated waste gas is then discharged from the main body 1 of the treatment device through the air outlet pipe 3 via the air pump 4. When using the connecting device 6, the support rod 612 is manually slid into the connecting cylinder 613, and the fixing rod 615 is passed through the rectangular plate 614, allowing the fixing rod 615 to pass through... Through the connecting cylinder 613 and the support rod 612, the second spring 616 pulls the fixing rod 615 towards the rectangular plate 614, thus effectively confining the fixing rod 615 inside the support rod 612. This effectively confines the support rod 612 inside the processing device body 1. Then, the rectangular strip 603 slides into the rectangular groove 604, thereby pressing the rubber strip 605 into the locking groove 606. This effectively positions the arc plate 602 at the notch 601 and provides a certain degree of sealing. The first spring 610 then pushes the rubber strip 605 towards the notch 601. Pressing the moving ring 609 causes the rubber ring 611 to be pressed against the connection between the arc plate 602 and the main body 1 of the treatment device. This effectively confines the arc plate 602 inside the notch 601 and provides a certain degree of sealing. This also allows the connecting frame 5 to be properly positioned inside the main body 1 of the treatment device, facilitating the replacement of the activated carbon inside the connecting frame 5. When using the heat dissipation device 7, because the polyurethane screen production process generates relatively high temperatures, the resulting exhaust gas will also have relatively high temperatures. Therefore, when the exhaust gas passes through the iron plate 701, the heat from the exhaust gas will be transferred through the iron plate 701. Plate 701 exchanges heat with the outside environment. The iron ring 703 can increase the contact area of plate 701 to a certain extent, thus improving the heat dissipation efficiency of plate 701. Since the positioning frame 708 is set on one side of plate 701, the connecting box 704 can be placed on the surface of the main body 1 of the treatment device. The water pump 706 circulates water inside the connecting box 704 and the connecting pipe 705, which can change the surface temperature of the main body 1 of the treatment device to a certain extent, thereby playing a certain cooling role and preventing high-temperature exhaust gas from affecting the activity of activated carbon.
[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
