Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment devices, and in particular to a waste gas treatment device used for herbicide production. Background Art

[0002] Herbicides are agents that can kill weeds completely or selectively. They are a type of substance used to eliminate or inhibit plant growth, also known as weed killers.

[0003] In the herbicide production process, waste gas treatment is a crucial link, and its main purpose is to reduce the harm to the environment and human health. In the prior art, the waste gas generated during production is first introduced into water, and the soluble pollutants such as sulfide and ammonia contained in the waste gas are dissolved by the contact between the waste gas and the water.

[0004] However, when the concentration of pollutants in the exhaust gas is high, the water may quickly reach a saturated state. At this time, the water needs to be replaced to maintain the treatment efficiency. The existing technology replaces the water by first discharging the saturated water in the water tank and then refilling the water tank. However, there is a problem of low water replacement efficiency, which is not conducive to the continuous and efficient treatment of the exhaust gas by the treatment device.

[0005] Based on the above-mentioned defects, a waste gas treatment device for herbicide production is provided. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 7 The present invention provides a technical solution: a waste gas treatment device for herbicide production, comprising a shell cover 1 and a filter cartridge 31 installed on the shell cover 1, a rotary disc 4 is rotatably connected to the inner side of the shell cover 1, three water storage tanks 6 distributed in an annular shape are fixedly arranged at the bottom of the rotary disc 4, a vent 5 is formed through the rotary disc 4, an air intake pipe 2 is arranged in the shell cover 1, the air intake pipe 2 is fixed to the shell cover 1 through a shell sleeve 18, a column 3 is fixedly arranged at the bottom of the air intake pipe 2, and an air guide component is arranged at the bottom of the rotary disc 4 to cooperate with the air intake pipe 2 to transport air to the water storage tank 6.

[0033] The waste gas generated during the production of herbicides enters the water storage tank 6 located below the filter cartridge 31 through the air guide component after entering the air inlet pipe 2. The filter cartridge 31 is provided with an ultraviolet lamp for irradiating the harmful waste gas after water treatment. When the waste gas entering the water storage tank 6 is discharged from the water, it will enter the filter cartridge 31 through the vent 5, and after irradiation treatment, it will be discharged from the filter cartridge 31 through the filter screen. An alkaline filter bag is placed in the filter screen to neutralize the acidic impurities contained in the waste gas.

[0034] A slip ring 8 slides through the shell cover 1, and a toothed disc 12 is rotatably connected to the bottom of the shell cover 1. A driving member for controlling the rotation of the toothed disc 12 is provided on the shell cover 1. A linkage component and a transmission component are provided on the inner side of the shell cover 1. When the water tank 6 below the filter cartridge 31 is switched, as the toothed disc 12 rotates, the slip ring 8 is first lifted off the turntable 4 under the action of the linkage component, and then the turntable 4 rotates under the action of the transmission component to switch the position of the water tank 6. Finally, the filter cartridge 31 is pressed into the vent 5 under the action of the linkage component.

[0035] If the concentration of pollutants in the exhaust gas is high, the water may reach a saturated state quickly. At this time, the water needs to be replaced to maintain the treatment efficiency. The gear disc 12 is controlled to rotate by the driving member, so that the slip ring 8 is first pulled upward from the vent 5 in the turntable 4 under the action of the linkage component. As the gear disc 12 continues to rotate, the slip ring 8 will remain in the lifted state, and the turntable 4 will rotate to replace the water tank 6 located below the filter cartridge 31. After completing the replacement of the water tank 6, the gear disc 12 continues to rotate, and the slip ring 8 will be pressed downward into the corresponding vent 5 under the action of the linkage component.

[0036] By directly rotating and replacing the water storage tank 6 that has reached a saturated state, it is beneficial for the device to continuously and efficiently treat the waste gas generated during the production of the herbicide, thereby achieving the purpose of improving the waste gas treatment efficiency.

[0037] A retaining ring is fixedly provided on the inner wall of the vent 5 to cooperate with the lower port of the slip ring 8, and a circular ring is also formed on the upper port of the slip ring 8 to cooperate with the top of the shell cover 1. When the slip ring 8 is pressed into the vent 5, the downward port of the slip ring 8 is in close contact with the retaining ring, and the circular ring of the upward port of the slip ring 8 is in close contact with the top end face of the shell cover 1, thereby preventing the exhaust gas from being discharged directly to the outside without being irradiated by the ultraviolet lamp and the action of the filter, thereby ensuring the treatment effect of the exhaust gas.

[0038] The top port of the slip ring 8 can achieve a sealing effect through a flexible rubber sleeve connected to the inner wall of the filter cartridge 31 .

[0039] A drainage groove 7 is formed at the bottom of the water storage tank 6 , and a rotating opening and closing component for controlling the opening and closing of the drainage groove 7 is provided at the bottom of the water storage tank 6 . A water delivery port 32 is formed in the shell cover 1 .

[0040] When the water storage tank 6 is located below the filter cartridge 31 and the water delivery port 32 as the rotary disk 4 rotates, the drainage groove 7 is in a closed state to accommodate water. When the water in the water storage tank 6 reaches a saturated state, as the rotary disk 4 rotates 120 degrees, the drainage groove 7 will be in an open state to discharge the water in the water storage tank 6 to the outside.

[0041] Specifically, Figure 3 and Figure 6 As shown, the air guide component includes a sleeve 22 coaxially fixed to the bottom of the turntable 4, and the output end of the air inlet pipe 2 passes through the shell cover 1 and extends into the sleeve 22. The side of the sleeve 22 is connected with three air guide pipes 23 extending into the water tank 6. The side of the air inlet pipe 2 facing the filter cartridge 31 is formed with a hole groove 201 that cooperates with the air guide pipe 23.

[0042] The exhaust gas introduced into the air intake pipe 2 will enter the corresponding water tank 6 through the air guide pipe 23 aligned with the hole groove 201. During the rotation and switching of the water tank 6, the sleeve 22 fixed at the bottom of the turntable 4 will rotate along the outer side of the air intake pipe 2. At this time, the air guide pipe 23 and the hole groove 201 are staggered until the water tank 6 reaches the lower position of the filter cartridge 31 as the turntable 4 rotates. The air guide pipe 23 corresponding to the water tank 6 is docked with the hole groove 201 to achieve the absorption of the exhaust gas.

[0043] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the driving member includes a ring 17 rotatably sleeved on the outside of the intake pipe 2, the ring 17 passes through the shell cover 1 and is coaxially fixed with the gear plate 12, a wheel 19 is rotatably connected in the shell cover 1, a driving motor 20 for controlling the rotation of the wheel 19 is installed on the shell cover 18, and a chain 21 is provided on the outer side of the wheel 19 and the ring 17.

[0044] The driving motor 20 is started to control the wheel disc 19 to rotate, so that the collar 17 drives the toothed disc 12 to rotate synchronously under the action of the chain 21. The outer sides of the collar 17 and the wheel disc 19 are both provided with teeth that mesh with the chain 21.

[0045] Specifically, Figure 2-Figure 6 As shown, the linkage component includes a gear ring 10 rotatably sleeved on the outside of the slip ring 8 and a guide assembly arranged in the gear ring 10. The gear ring 10 is rotatably connected to the bottom of the shell cover 1 and meshed with the gear disc 12.

[0046] When the toothed disc 12 rotates, it will drive the gear ring 10 meshing therewith to rotate synchronously. The transmission ratio of the toothed disc 12 to the gear ring 10 is 4:1.

[0047] The guide assembly includes a protrusion 11 fixed on the inner wall of the gear ring 10, and a slide rail 9 is formed on the side wall of the slip ring 8 to slide with the protrusion 11. The slide rail 9 is composed of a plurality of inverted V-shaped annular grooves and horizontal annular grooves connected end to end.

[0048] When the gear ring 10 rotates, the protrusion 11 fixed on the inner wall of the gear ring 10 will slide along the slide rail 9. During this process, the protrusion 11 first slides from the wave crest of the inverted V-shaped annular groove to the horizontal annular groove, and the protrusion 11 compresses and transmits the slide rail 9, driving the slip ring 8 to slide upward along the shell cover 1. When the protrusion 11 slides along the horizontal annular section of the slide rail 9, the slip ring 8 will remain in a lifted state. When the protrusion 11 slides from the horizontal annular section to the wave crest of the inverted V-shaped annular groove, the protrusion 11 compresses and transmits the slide rail 9, driving the slip ring 8 to slide downward along the shell cover 1. The inner wall of the slip ring 8 and the filter cartridge 31 that are slidably fitted should be provided with a sliding-fitting strip block and a strip groove to limit the rotation of the slip ring 8 relative to the filter cartridge 31, thereby facilitating the transmission of the slip ring 8 by the gear ring 10.

[0049] Specifically, Figure 3-Figure 6 As shown, the transmission component includes an insertion rod 13 slidably arranged in the toothed disc 12, three annular slots 401 are formed in the rotating disc 4, and a component for adjusting the plugging state of the insertion rod 13 and the slots 401 is arranged at the bottom of the shell cover 1.

[0050] When the insert rod 13 is inserted into the slot 401 , the rotating disk 4 will rotate synchronously with the toothed disk 12 .

[0051] The component for adjusting the plug-in state of the plug rod 13 and the slot 401 includes a magnetic block 14 fixed on the plug rod 13, a side extension rod 15 fixed to the side end of the magnetic block 14, a slideway 16 for cooperating with the side extension rod 15 is formed on the side wall of the intake pipe 2, and two magnetic sheets 30 for cooperating with the magnetic block 14 are fixed at the bottom of the shell cover 1, and the magnetic poles of the two magnetic sheets 30 are opposite.

[0052] When the toothed disc 12 rotates along the outward direction of the intake pipe 2, the side extension rod 15 fixed on the magnetic block 14 will slide along the slideway 16, and the relative position of the insertion rod 13 and the toothed disc 12 is limited by the sliding cooperation between the slideway 16 and the side extension rod 15.

[0053] The slide 16 is composed of two annular sections distributed up and down and a vertical section connecting the two annular sections at the end. When the side extension rod 15 slides from the upper annular section to the vertical section, the magnetic block 14 drives the insertion rod 13 to be inserted into the slot 401 under the repulsive force of the magnetic sheet 30 of the same pole. When the side extension rod 15 slides from the lower annular section to the other vertical section, the magnetic block 14 drives the insertion rod 13 to be pulled out of the slot 401 under the magnetic attraction of the magnetic sheet 30 of the opposite pole.

[0054] When the water tank 6 is switched, as the toothed disc 12 rotates one hundred and twenty degrees, the gear ring 10 rotates thirty degrees. During this process, the side extension rod 15 slides along the annular section on the upper side of the slideway 16, and the protrusion 11 slides along the crest of the inverted V-shaped annular groove of the slide rail 9 toward the horizontal annular groove until the side extension rod 15 slides to the intersection of the annular section and the vertical section, the slip ring 8 lifts upward from the turntable 4, and the magnetic block 14 drives the insertion rod 13 to be inserted into the slot 401 under the repulsive force of the magnetic piece 30 of the same pole.

[0055] As the toothed disc 12 continues to rotate one hundred and twenty degrees, the toothed disc 12 will drive the turntable 4 to rotate and switch the water tank 6 located below the filter cartridge 31. During this process, the side extension rod 15 will slide along the annular section located on the lower side of the slide 16, and the protrusion 11 will slide along the horizontal annular groove of the slide rail 9. The slip ring 8 will remain in a lifted state until the side extension rod 15 slides to the intersection of the annular section and another vertical section. At this time, the magnetic block 14 will drive the insertion rod 13 to be pulled out of the slot 401 under the suction force of the opposite polar magnetic piece 30.

[0056] Thereafter, the toothed disc 12 continues to rotate one hundred and twenty degrees, the side extension rod 15 will slide along the annular section located on the upper side, and the protrusion 11 will slide along the slide rail 9 from the horizontal annular groove to the wave crest of the inverted V-shaped annular groove. During this process, the rotating disc 4 remains stationary relative to the shell cover 1, and the slip ring 8 will be pressed downward into the corresponding vent 5.

[0057] Only by controlling the rotation of the toothed disc 12, the toothed disc 12 rotates one circle, driving the gear ring 10 to rotate a quarter circle, so as to control the slip ring 8 to first lift up from the rotary disc 4, and then drive the rotary disc 4 to rotate to switch the water tank 6 under the filter cartridge 31, and finally press the slip ring 8 down to the vent 5 that has been switched into place, thereby achieving the purpose of simplifying the equipment operation procedure.

[0058] Specifically, Figure 6 and Figure 7 As shown, the rotating opening and closing component includes a rotating plate 24 rotatably connected to the water tank 6, and a rotating frame 25 is rotatably connected to the outer side of the column 3. A sliding rod 26 corresponding to the rotating plate 24 slides vertically in the rotating frame 25. A pressing component for acting downward on the sliding rod 26 is provided on the column 3. An open groove for cooperating with the sliding of the sliding rod 26 is formed in the rotating plate 24, and a pressure plate 27 is fixed on the sliding rod 26.

[0059] One end of the rotary plate 24 extends into the inner side of the water tank 6 to control the opening and closing of the drainage groove 7, and the other end extends outward from the outside of the water tank 6. The pressing component acts downward to extend the rotary plate 24 outward from one side of the water tank 6, driving the rotary plate 24 to rotate along the water tank 6, so that the rotary plate 24 extends into one side of the water tank 6 and lifts up to block the bottom of the drainage groove 7.

[0060] The pressing assembly includes a baffle 28 fixed to the outer end of the side extension rod 15, and a contact block 29 is fixed to the bottom of the baffle 28. The bottom of the contact block 29 is formed with a step surface that matches the top of the slide rod 26 and a slope surface that presses the slide rod 26 downward.

[0061] The end face of the abutment block 29 is composed of a horizontal end face, a vertical end face and a slope face. When the water storage tank 6 rotates away from the bottom of the filter cartridge 31 as the rotary disk 4 rotates, the slide bar 26 slides away from the horizontal end face along the bottom of the abutment block 29. At this time, the water in the water storage tank 6 will flush the rotary plate 24 under the action of gravity and be discharged outward from the drainage groove 7, and the pressure plate 27 will drive the slide bar 26 upward to contact the baffle plate 28 as the rotary plate 24 rotates.

[0062] When the water storage tank 6 rotates toward the water delivery port 32 along with the rotary disk 4, the slope of the abutment block 29 presses the slide bar 26 downward, so that the pressure plate 27 acts downward on the side of the rotary plate 24 extending outward from the water storage tank 6, and then the side of the rotary plate 24 extending inward into the water storage tank 6 is lifted up under the action of the lever, thereby blocking the drainage groove 7. When the water storage tank 6 is located below the water delivery port 32 and the filter cartridge 31, the top of the slide bar 26 is in contact with the horizontal end surface of the abutment block 29, ensuring that the rotary plate 24 maintains a stable blocking state for the drainage groove 7.

[0063] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
