Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for sewage hose production. Background Art

[0002] The background technology for waste gas treatment devices used in sewage hose production primarily relates to waste gas emission management, environmental protection, and the need for waste gas control in industrial production. With the increasing demand for environmental protection, waste gas emissions from industrial production processes have become a significant environmental protection issue. The production of sewage hose involves the release of certain chemicals and hazardous gases. If these gases are released into the atmosphere without effective treatment, they can pose serious risks to air quality, the environment, and human health.

[0003] Chinese patent CN115999327B, authorized and published on September 26, 2023, discloses a waste gas treatment device for hot melt pressure-sensitive adhesive production. The device comprises a spray tower, a recovery tower base fixedly mounted below the spray tower, a spray head fixedly mounted on the top of the spray tower, a liquid inlet pipe connected to the top of the spray head, and a heating pipe fixedly mounted inside the liquid inlet pipe. In the above application document, a stationary imbrication layer is used to increase the reaction time between the treatment liquid and the waste gas, thereby improving the treatment effect of the device. However, the stationary imbrication layer has a relatively limited effect on increasing the contact area and contact time between the treatment liquid and the waste gas, resulting in a low absorption efficiency of the treatment liquid for the waste gas. Summary of the Invention

[0004] In response to the shortcomings of the prior art, the present invention provides a waste gas treatment device for waste hose production, which solves the problems raised in the above-mentioned background art. To achieve the above objectives, the present invention is implemented through the following technical solutions: A waste gas treatment device for waste hose production, comprising a spray tower body, one end of which is equipped with a waste gas inlet pipe, the other end of which is equipped with a waste gas outlet pipe and an air inlet pipe, and the top of the spray tower body is equipped with a liquid inlet pipe;

[0005] The spray tower body is internally rotatably connected to a rotating sleeve driven by a servo motor. A fixed seat is fixedly connected to the outside of the rotating sleeve. Rotating rods 1, 2, and 3 are rotatably connected to the inside of the fixed seat. Gear 1, bevel gear 1, and sprocket 1 are fixedly connected to the outside of rotating rod 1. An arc-shaped gear ring is fixedly connected to the inside of the spray tower body. Bevel gear 2 is fixedly connected to the side of rotating rod 2. Rotating plate 1 is fixedly connected to the outside of rotating rod 2. A chain is installed on the outside of sprocket 1. Sprocket 2 and rotating plate 2 are fixedly connected to the outside of rotating rod 3. A closing assembly for introducing exhaust gas and a spray assembly for injecting treatment liquid are respectively installed inside the spray tower body. This allows for deep agitation of the exhaust gas and treatment liquid, improving the treatment liquid's efficiency in absorbing the exhaust gas.

[0006] Preferably, when the gear moves to the arc-shaped gear ring, it can engage with the arc-shaped gear ring.

[0007] Preferably, one end of the chain away from the sprocket one is assembled on the outer side of the sprocket two.

[0008] Preferably, the closing assembly includes a hydraulic device partially assembled in a rotating sleeve, a cam fixedly connected to the outer side of the rotating rod (3), a force rod slidably connected to one end of the hydraulic device, a push rod (1) slidably connected to one end of the hydraulic device, a push rod (2) slidably connected to the other end of the hydraulic device, a spring (1) mounted on the side of the force rod, a transmission rod (1) rotatably connected to the inside of the exhaust gas inlet pipe, a force plate (1) fixedly connected to the outer side of the transmission rod (1), a block (1) fixedly connected to the bottom of the transmission rod (1), a transmission rod (2) rotatably connected to the inside of the exhaust gas outlet pipe, a force plate (2) fixedly connected to the outer side of the transmission rod (2), a block (2) fixedly connected to the bottom of the transmission rod (2). This prevents the newly introduced exhaust gas from being directly discharged without being absorbed, thereby improving the absorption effect of the device.

[0009] Preferably, the hydraulic device is composed of two sections of rigid storage bodies, and the two sections of rigid storage bodies are in a rotationally connected state.

[0010] Preferably, the force-bearing rod is located at a side position of the cam and is in contact with the cam.

[0011] Preferably, the spray assembly includes a hydraulic chamber extending through the spray tower body, a second gear fixedly connected to the top of the second transmission rod, a first gear slidably connected to one end of the hydraulic chamber, and a second gear slidably connected to the other end of the hydraulic chamber. The bottom of the liquid inlet pipe is rotatably connected to a pipe joint, a third gear fixedly connected to the outside of the pipe joint, and a spray head fixedly connected to the bottom of the pipe joint. This increases the coverage area of ​​the treatment liquid, thereby increasing the contact area between the treatment liquid and the exhaust gas, further enhancing the absorption effect of the device.

[0012] Preferably, the gear rod 1 is in meshing state with the gear rod 2, and the gear rod 3 is in meshing state with the gear rod 2.

[0013] The present invention provides a waste gas treatment device for sewage hose production, which has the following beneficial effects:

[0015] (2) The sewage hose is used to produce waste gas treatment equipment. When the rotating rod 3 is in the rotating state, it can drive the cam to rotate synchronously, and cooperate with the hydraulic device, the force rod, the push rod 1, the push rod 2, the spring 1, the transmission rod 1, the force plate 1, the block 1, the transmission rod 2, the force plate 2 and the block 2, so that the waste gas inlet pipe and the waste gas outlet pipe are in the open and closed states in turn, preventing the waste gas that has just been introduced from being discharged directly without being absorbed, thereby improving the absorption effect of the device.

[0016] (3) The sewage hose produces a waste gas treatment device. When the transmission rod 2 rotates back and forth, it cooperates with the hydraulic chamber, gear 2, gear rod 1, gear rod 2, pipe joint, gear 3 and spray head to rotate and spray the treatment liquid into the spray tower body, thereby increasing the coverage area of ​​the treatment liquid, thereby increasing the contact area between the treatment liquid and the waste gas, and further improving the absorption effect of the device.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Example 1

[0032] See also Figure 1-Figure 3 A sewage hose production waste gas treatment device includes a spray tower body 100, one end of the spray tower body 100 is equipped with a waste gas inlet pipe 200, the other end of the spray tower body 100 is equipped with a waste gas outlet pipe 300 and an air inlet pipe 400, and the top of the spray tower body 100 is equipped with a liquid inlet pipe 500;

[0033] A rotating sleeve 601, driven by a servo motor, is rotatably connected to the interior of the spray tower 100. A fixed base 602 is fixedly connected to the exterior of the rotating sleeve 601. Exhaust gas, air, and treatment liquid are introduced into the spray tower 100 through the exhaust gas inlet pipe 200, the air inlet pipe 400, and the liquid inlet pipe 500. The servo motor is then activated, driving the rotating sleeve 601, which in turn rotates the fixed base 602, which is fixedly connected to it.

[0034] The interior of the fixed seat 602 is rotatably connected to a rotating rod 1 603, a rotating rod 2 604, and a rotating rod 3 605. The exterior of the rotating rod 1 603 is fixedly connected to a gear 1 606, a bevel gear 1 607, and a sprocket 1 608. The interior of the spray tower body 100 is fixedly connected to an arcuate gear ring 609. When the gear 1 606 moves to the arcuate gear ring 609, it can mesh with the arcuate gear ring 609. When the fixed seat 602 rotates, the gear 1 606 on the fixed seat 602 also revolves. When the gear 1 606 rotates to the arcuate gear ring 609, the gear 1 606 is restrained by the arcuate gear ring 609 and simultaneously rotates on its own while revolving. The rotating gear 1 606 drives the rotating rod 1 603 to which it is fixed to rotate.

[0035] A bevel gear 2 610 is fixedly connected to the side of rotating rod 2 604, and a rotating plate 1 611 is fixedly connected to the outer side of rotating rod 2 604. When rotating rod 1 603 rotates bevel gear 1 607, which is fixedly connected to it, bevel gear 1 607 rotates bevel gear 2 610, which in turn rotates rotating rod 2 604, which in turn rotates rotating plate 1 611, which is fixedly connected to it.

[0036] A chain 612 is installed on the outside of sprocket one 608, and the outside of rotating rod three 605 is fixedly connected to sprocket two 613 and rotating plate two 614 respectively. The end of chain 612 away from sprocket one 608 is installed on the outside of sprocket two 613. The interior of the spray tower body 100 is respectively equipped with a closing component 700 for introducing exhaust gas and a spray component 800 for spraying treatment liquid. When the rotating rod 1 603 drives the sprocket 1 608 fixedly connected to it to rotate, the chain 612 assembled on the outside of the sprocket 1 608 cooperates to make the sprocket 2 613 connected to the sprocket 1 608 through the chain 612 rotate, and the sprocket 2 613 drives the rotating rod 3 605 fixedly connected to it to rotate, so that the rotating rod 3 605 drives the rotating plate 2 614 fixedly connected to it to rotate; the rotating plate 1 611 and the rotating plate 2 614 are in different rotation directions, which deeply stirs the exhaust gas and treatment liquid located in the spray tower body 100, thereby improving the absorption efficiency of the treatment liquid for the exhaust gas.

[0037] During use, waste gas, air and treatment liquid are introduced into the spray tower body 100 through the waste gas inlet pipe 200, the air inlet pipe 400 and the liquid inlet pipe 500, and then the servo motor is started to drive the rotating sleeve 601 driven by the servo motor to rotate, so that the rotating sleeve 601 drives the fixed seat 602 fixedly connected thereto to rotate, and the gear 1 606 on the fixed seat 602 rotates together therewith. When the gear 1 606 rotates to the arc-shaped gear ring 609, the gear 1 606 is restricted by the arc-shaped gear ring 609 and rotates synchronously while rotating. The rotating gear 1 606 drives the rotating rod 1 603 fixedly connected thereto to rotate; the rotating rod 1 603 drives the bevel gear 1 607 fixedly connected thereto to rotate, so that the bevel gear 1 607 drives The bevel gear 2 610 meshing with it rotates, and the bevel gear 2 610 drives the rotating rod 2 604 fixedly connected to it to rotate, so that the rotating rod 2 604 drives the rotating plate 1 611 fixedly connected to it to rotate; the rotating rod 1 603 drives the sprocket 1 608 fixedly connected to it to rotate, and cooperates with the chain 612 assembled on the outside of the sprocket 1 608 to make the sprocket 2 613 connected to the sprocket 1 608 through the chain 612 rotate, and the sprocket 2 613 drives the rotating rod 3 605 fixedly connected to it to rotate, so that the rotating rod 3 605 drives the rotating plate 2 614 fixedly connected to it to rotate; and the rotating plate 1 611 and the rotating plate 2 614 are in different rotation directions, which deeply stirs the exhaust gas and treatment liquid located in the spray tower body 100.

[0038] Example 2

[0039] See also Figures 1-8 Based on the first embodiment, the closing assembly 700 includes a hydraulic device 701 partially assembled within the rotating sleeve 601. The hydraulic device 701 is composed of two rigid housing sections, which are rotatably connected to each other. A cam 702 is fixedly connected to the outer side of the rotating rod 3 605. A force-bearing rod 703 is slidably connected to one end of the hydraulic device 701. The force-bearing rod 703 is located to the side of the cam 702 and contacts the cam 702. When the rotating rod 3 605 is in a rotating state, it can drive the cam 702, which is fixedly connected to the rotating rod 3 605, to rotate synchronously. When the protruding portion of the cam 702 rotates to the force-bearing rod 703, it can squeeze the force-bearing rod 703 and drive the force-bearing rod 703 to move into the hydraulic device 701. In cooperation with the hydraulic device 701 slidably connected to the force-bearing rod 703, the pressure within the hydraulic device 701 increases.

[0040] One end of the hydraulic device 701 is slidably connected to a push rod 1 704, and the other end of the hydraulic device 701 is slidably connected to a push rod 2 705. A spring 1 706 is mounted on the side of the force-bearing rod 703. A transmission rod 1 707 is rotatably connected to the interior of the exhaust gas intake pipe 200 and extends therethrough. A force-bearing plate 1 708 is fixedly connected to the outer side of the transmission rod 1 707, and a blocking block 1 709 is fixedly connected to the bottom of the transmission rod 1 707. When the pressure within the hydraulic device 701 increases, it drives the push rod 1 704 and push rod 2 705, which are slidably connected to the hydraulic device 701, to move. Push rod 1 704 drives the force-bearing plate 1 708, which is fixedly connected to it, to rotate. This in turn drives the force-bearing plate 1 708, which in turn drives the transmission rod 1 707, which in turn drives the blocking block 1 709, which is fixedly connected to it, to rotate.

[0041] The exhaust gas outlet pipe 300 is internally connected to a transmission rod 710 that passes through it. The outer side of the transmission rod 710 is fixedly connected to a force plate 711. The bottom of the transmission rod 710 is fixedly connected to a blocking block 712. Similarly, when the push rod 705 moves, the blocking block 712 can be driven to rotate through the transmission rod 710 and the force plate 711. At this time, Figure 4 As shown, the exhaust gas inlet pipe 200 is in an open state, while the exhaust gas outlet pipe 300 is in a closed state, thereby introducing exhaust gas into the spray tower body 100 and stopping the discharge of the treated exhaust gas. When the protruding portion of the cam 702 rotates away from the force-bearing rod 703, the force-bearing rod 703 can be reset under the action of spring 1 706, and similarly, the block 1 709 and the block 2 712 can be reset. In this way, the exhaust gas inlet pipe 200 and the exhaust gas outlet pipe 300 can be opened and closed in turn, preventing the exhaust gas that has just been introduced from being directly discharged without being absorbed, thereby improving the absorption effect of the device.

[0042] When in use, based on the embodiment 1, when the rotating rod 3 605 is in the rotating state, it can drive the cam 702 fixedly connected to the rotating rod 3 605 to rotate synchronously, and when the protruding part of the cam 702 rotates to the force-bearing rod 703, it can squeeze the force-bearing rod 703 and drive the force-bearing rod 703 to move into the hydraulic device 701, and cooperate with the hydraulic device 701 slidably connected to the force-bearing rod 703, so that the pressure in the hydraulic device 701 increases, driving the push rod 1 704 and the push rod 2 705 slidably connected to the hydraulic device 701 to move, and the push rod 1 704 drives the force-bearing plate 1 708 fixedly connected thereto to rotate, so that the force-bearing plate 1 708 drives the transmission rod 1 707 fixedly connected thereto to rotate, so that the transmission rod 1 707 drives the blocking block 1 709 fixedly connected thereto to rotate. Similarly, with the movement of the push rod 2 705, the blocking block 2 712 can be driven to rotate through the transmission rod 2 710 and the force-bearing plate 2 711. At this time, Figure 4As shown, the exhaust gas inlet pipe 200 is in an open state, and the exhaust gas outlet pipe 300 is in a closed state, thereby introducing exhaust gas into the spray tower body 100 and stopping the discharge of the treated exhaust gas; when the protruding part of the cam 702 rotates away from the force-bearing rod 703, the force-bearing rod 703 can be reset under the action of spring 1 706, and similarly, the block 1 709 and the block 2 712 are reset.

[0043] Example 3

[0044] See also Figures 1-9 Based on the first and second embodiments, the spray assembly 800 includes a hydraulic chamber 801 that extends through the spray tower body 100. The top of the second transmission rod 710 is fixedly connected to a second gear 802. One end of the hydraulic chamber 801 is slidably connected to a first gear 803, which is meshed with the second gear 802. When the second transmission rod 710 rotates back and forth, it drives the second gear 802, which is connected to it, to rotate back and forth, causing the second gear 802 to drive the meshed first gear 803 to reciprocate. The other end of the hydraulic chamber 801 is slidably connected to a second gear 804. The bottom of the liquid inlet pipe 500 is rotatably connected to a pipe joint 805. The outer side of the pipe joint 805 is fixedly connected to a third gear 806, which is meshed with the second gear 804. A spray head 807 is fixedly connected to the bottom of the pipe joint 805. When gear rod 1 803 moves back and forth, it cooperates with the hydraulic chamber 801 that is slidingly connected to gear rod 1 803, which can drive gear rod 2 804 that is slidingly connected to the hydraulic chamber 801 to move back and forth, so that gear rod 2 804 drives gear 3 806 that is meshed with it to rotate back and forth, and gear 3 806 drives the pipe joint 805 that is fixedly connected to it to rotate back and forth, so that the pipe joint 805 drives the spray head 807 that is fixedly connected to it to rotate back and forth, and the treatment liquid introduced through the liquid inlet pipe 500 can be sprayed out by reciprocating rotation, thereby increasing the coverage area of ​​the treatment liquid, thereby increasing the contact area between the treatment liquid and the exhaust gas, and further improving the absorption effect of the device.

[0045] During use, based on Example 1 and Example 2, when the transmission rod 2 710 rotates back and forth, it can drive the gear 2 802 connected to it for transmission to rotate back and forth, so that the gear 2 802 drives the gear rod 1 803 engaged with it to move back and forth, and cooperates with the hydraulic warehouse 801 slidingly connected to the gear rod 1 803, which can drive the gear rod 2 804 slidingly connected to the hydraulic warehouse 801 to move back and forth, so that the gear rod 2 804 drives the gear 3 806 engaged with it to rotate back and forth, and the gear 3 806 drives the pipe joint 805 fixedly connected to it to rotate back and forth, so that the pipe joint 805 drives the spray head 807 fixedly connected to it to rotate back and forth, and the treatment liquid introduced through the liquid inlet pipe 500 can be sprayed out by rotating back and forth.
