Description

Technical Field

[0001] The present invention relates to the field of pesticide production, and particularly to an exhaust gas recovery device for pesticide production. Background Art

[0002] In a patent application for an exhaust gas solvent recovery device and method for pesticide production with the application number CN202411367215.7, it includes a recovery mechanism and a clamping mechanism. Among them, the recovery mechanism includes a box body. A recovery chamber is opened inside the box body. A mounting rack is fixedly installed on the inner wall of the recovery chamber. A fixing plate is movably installed at the front end of the mounting rack. An activated carbon net is movably installed between the mounting rack and the fixing plate. An air inlet channel and an air outlet channel are respectively opened at the bottom end and the top end of the recovery chamber. The input end of the air inlet channel is communicated with an air inlet. The output end of the air outlet channel is communicated with an exhaust port. Both the air inlet and the exhaust port are arranged at the rear end of the box body, and the air inlet is arranged below the exhaust port. This invention is easy to operate, has a stable structure, low maintenance cost, and also greatly reduces the downtime, improves the continuity of exhaust gas treatment and environmental protection effect, and has significant economic and social benefits.

[0003] In the prior art including the above patent, when filtering by the adsorption method, after the filter plate in the exhaust gas recovery filter barrel is used for a period of time, it needs to be replaced because it adsorbs a large amount of impurities. The previous replacement methods mostly rely on manual operation. The staff needs to directly open the exhaust gas recovery filter barrel, manually take out the old filter plate and replace it with a new one. However, since there are still incompletely treated exhaust gases remaining in the exhaust gas recovery filter barrel, these exhaust gases often contain various harmful chemical substances to the human body, such as volatiles of pesticide components such as organophosphorus and organochlorine. During the process of opening the barrel, the exhaust gas is extremely likely to leak. If the staff is exposed to such an environment for a long time, it will cause damage to the respiratory system, nervous system, etc., seriously threatening physical health. At the same time, the manual operation efficiency is low, affecting the production progress.

[0004] Therefore, it is very necessary to invent an exhaust gas recovery device for pesticide production to solve the above problems. Summary of the Invention

[0016] 1. Through the coordinated operation of each component, the equipment solves the common problems existing in the existing equipment when filtering by the adsorption method. The adsorption method causes blockage on the surface of the filter plate, and the filtering effect of the filter plate is poor. When the filter plate needs to be replaced, the equipment realizes the automatic replacement of the filter plate. The whole process does not require direct operation by personnel, effectively avoiding the potential harm to the physical health of personnel caused by the leakage of waste gas in the barrel when opening the waste gas recovery and filtration barrel to replace the filter plate.

The waste water is evenly sprayed from the water spray holes arranged in a circular array, covering the filter plate comprehensively and strongly flushing the attached particulate matter, effectively avoiding the blockage of the filter plate. At the same time, the fan blades rotate under the action of the water flow, further enhancing the cleaning effect and greatly improving the cleaning efficiency. In addition, the unique design of the funnel-shaped blanking slope enables the flushed waste water and impurities to quickly gather and flow into the waste water pipe, avoiding accumulation in the barrel and ensuring the cleanliness inside the equipment. This convenient cleaning and maintenance design not only saves a large amount of cleaning time and labor costs, but also can effectively extend the service life of the equipment, reduce the equipment maintenance frequency, ensure the long-term stable operation of the waste gas recovery device, and make the pesticide production process smoother and more efficient.

[0053] Working principle:

[0054] First of all, in the first step, the waste gas generated in pesticide production is input into the inner cavity of the waste gas recovery filter barrel 1 through the air inlet end. At this time, the waste gas in the waste gas recovery filter barrel 1 is pumped away by the air pump connected to the other end of the exhaust pipe. During the process, the waste gas is filtered through a plurality of filter plates 4, and the impurity particles contained in the waste gas will be filtered by the filter plates 4 and adhered to the bottom of the filter plates 4.

[0055] In the second step, the control valve at the water inlet end is opened, and the waste water flow is conveyed from the water inlet end to the connecting seat 121 in the spraying mechanism 12. The waste water flow enters the spraying disc 123 and a plurality of water spraying holes through the connecting pipe 122 communicating with the connecting seat 121 and then sprays out. The sprayed waste water sprays the top of the filter plate 4. The waste water after spraying can wash the particulate matters adhered to the bottom of the filter plate 4, avoiding the blockage of the filter holes on the filter plate 4 by the particulate matters. Secondly, during the process of flushing and cleaning the filter plate 4 by the waste water, when passing through the filter plate 4, it can be filtered by the filter plate 4, realizing the function of filtering impurities and wastes in the waste water.

[0056] In the third step, when the filtering effect of the filter plate 4 decreases, the driving motor 131 is started to drive the bolt 132 to leave the positioning plate 133, and then the electric telescopic rod 21 is started. By the contraction of the electric telescopic rod 21, the sealing door plate 2 is pulled, so that the sealing door plate 2 is opened. The opened sealing door plate 2, together with the sealing inner plate 3 and a plurality of filter plates 4, is separated from the waste gas recovery filter barrel 1.

[0057] In the fourth step, place multiple new filter plates 4 on the top of the filter plate 4, start the intelligent robot 11, and the intelligent robot 11 drives the filter plate 4 into the positioning track on the base 5. When it touches the limit plate, the intelligent robot 11 stops. At this time, start the servo motor in the protective cover 6, drive the threaded rod to rotate through the motor, and cooperate with the interaction between the threads and the transmission connection of the belt. Multiple pushing plates 32 move horizontally on two adjacent threaded rods. When moving, they push the filter plate 4 located in the chute to realize automatic replacement of the filter plate 4. The replaced waste filter plate 4 is pushed onto the intelligent robot 11 on the other side of the waste gas recovery filter barrel 1 and is transported away by the intelligent robot 11;

[0058] During this replacement process, there is no need for personnel to be on-site for operation, avoiding the health problems of personnel caused by the leakage of waste gas in the waste gas recovery filter barrel 1 during the replacement of the filter plate 4, ensuring the health of personnel and improving the construction efficiency.

[0059] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention.
