[0002] Metal processing production specifically refers to the process of making full use of various metal materials to carry out deep processing and carefully manufacture products. Metal processing production has a wide range of different processes, such as the very common casting process, forging process, as well as turning, milling, stamping, welding and other processes, and these processes can be flexibly combined and reasonably applied according to the specific requirements of the product, so as to achieve the goal of producing metal products with different shapes, sizes and properties. It is particularly important to note that waste gas will inevitably be generated during the entire process of metal processing, and there are some gases in these waste gases that are harmful to the human body and the environment. Because of this, special suction and exhaust devices are usually required to properly handle the waste gas generated during metal processing;

[0003] The shortcomings of existing exhaust and intake devices used in metal processing production: When treating exhaust gas using traditional adsorption and filtration methods, since the exhaust gas generated in metal processing production contains smaller particles and fine particulate matter, these particles often pass through the adsorption layer, resulting in incomplete adsorption and filtration, and the purification effect is not obvious enough. These smaller particles may contain harmful substances, posing potential hazards to the environment and human health. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides an air intake and exhaust device for metal processing production, comprising a bottom plate and a primary filter box and a secondary filter box mounted on the top surface of the bottom plate, and a high-efficiency purification structure located inside the secondary filter box and in the middle of the primary filter box and the secondary filter box, wherein an adsorption purification structure is arranged inside the primary filter box;

The output end of the water pump is connected with a transmission pipe, and a circular hole is opened on the inner wall of the circulation pipe. The other end of the transmission pipe extends through and extends to the interior of the secondary filter box and is connected with the inner wall of the circular hole. An atomizing nozzle is installed on the outer wall of the circulation pipe. The output end of the water pump is connected with a water pumping pipe, and the other end of the water pumping pipe extends to the interior of the water storage tank. A filter screen is arranged below the atomizing nozzle.

[0006] The adsorption purification structure comprises an adsorption layer plate, a placement box located below the adsorption layer plate, and a through pipe with two ends connected to the primary filter box and the secondary filter box.

[0007] Preferably, the filter screen is inserted into the interior of the secondary filter box, a slide groove is provided on the front of the primary filter box, and a sealing door panel is slidably connected to the inner wall of the slide groove.

[0008] Preferably, an air pump is installed on the inner top wall of the preliminary filtration box, an air extraction pipe is connected to the output end of the air pump, and an air supply pipe is connected to the input end of the air pump.

[0009] Preferably, the air supply pipe is located above the adsorption layer plate, and the bottom of the secondary filter box is set at an angle of twenty-five degrees.

[0010] Preferably, the bottom surface of the water storage tank is fixedly connected to the center of the top surface of the bottom plate, and the two side surfaces of the water storage tank are tightly fitted with the outer walls of the primary filter box and the secondary filter box respectively, and the top surface of the secondary filter box is provided with a discharge pipe.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model, through the design of the adsorption purification structure and the high-efficiency structure, can firstly process the waste gas generated in the metal processing production through the adsorption purification structure, adsorb and filter most of the particulate matter and harmful substances, and then transmit the waste gas to the secondary filtering structure through the through pipe. In this process, the water pump draws water in the water storage tank and transmits it to the circulation pipe, and then sprays and atomizes it through the atomizing nozzle. After the atomization spraying, the tiny particles in the waste gas come into contact with the water mist, and gradually gather and condense into larger particles under the action of condensation and wetting, and fall to the bottom and settle due to gravity.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the utility model provides an air intake and exhaust device for metal processing production, comprising a bottom plate 1 and a primary filter box 2 and a secondary filter box 3 mounted on the top surface of the bottom plate 1, and a high-efficiency purification structure 4 located inside the secondary filter box 3 and in the middle of the primary filter box 2 and the secondary filter box 3, and an adsorption purification structure 5 is arranged inside the primary filter box 2;

[0021] The high-efficiency purification structure 4 includes a water storage tank 41 and a water pump 42 installed on the top of the water storage tank 41, and a circulation pipe 43 installed on the inner top wall of the secondary filter box 3. The output end of the water pump 42 is connected with a transmission pipe 44. A circular hole is opened on the inner wall of the circulation pipe 43. The other end of the transmission pipe 44 extends through and extends to the interior of the secondary filter box 3 and is connected with the inner wall of the circular hole. An atomizing nozzle 45 is installed on the outer wall of the circulation pipe 43. The output end of the water pump 42 is connected with a water pumping pipe 46. The other end of the water pumping pipe 46 extends to the interior of the water storage tank 41. A filter screen 47 is arranged below the atomizing nozzle 45.

[0022] The adsorption purification structure 5 includes an adsorption layer plate 51 and a placement box 52 located below the adsorption layer plate 51 , and a through pipe 53 with both ends connected to the primary filter box 2 and the secondary filter box 3 .

[0023] The above scheme is adopted: through the design of the adsorption purification structure 5 and the high-efficiency structure, the waste gas generated in the metal processing production is firstly treated by the adsorption purification structure 5 to adsorb and filter most of the particulate matter and harmful substances. Subsequently, the waste gas is transmitted to the secondary filtration structure through the through pipe 53. During this process, the water pump 42 extracts the water in the water tank 41 and transports it to the circulation pipe 43, and then sprays and atomizes it through the atomizing nozzle 45. After atomization spraying, the tiny particles in the waste gas contact with the water mist, and gradually gather and condense into larger particles under the action of condensation and wetting, and fall to the bottom and settle due to gravity. Through such two purification processes carried out in succession, the purification effect of the gas can be significantly increased, and the possible harm to the human body caused by the particulate matter contained in the waste gas can be greatly reduced, effectively ensuring the health and safety of the staff, and at the same time achieving a more thorough and effective purification of the waste gas.

[0024] like Figures 1 to 5 As shown, the filter screen 47 is inserted into the interior of the secondary filter box 3, and a slide groove is provided on the front of the primary filter box 2, and a sealing door panel 21 is slidably connected to the inner wall of the slide groove.

[0025] The above scheme is adopted: a sealing strip is adhered to the side of the sealing door panel 21 that contacts the preliminary filter box 2 to increase the sealing effect of the device, and the filter screen 47 can be cleaned and the activated carbon in the placement box 52 can be replaced by pushing the sealing door panel 21. The function of the placement box 52 is to place the activated carbon, and the function of the activated carbon is to absorb impurities and some harmful particulate matter in the exhaust gas through its own characteristics.

[0026] like Figures 1 to 5 As shown, an air pump 22 is installed on the inner top wall of the preliminary filtering box 2, an air extraction pipe 23 is connected through the output end of the air pump 22, and an air supply pipe 24 is connected through the input end of the air pump 22.

[0027] The above solution is adopted: the function of the air pump 22 is to provide a strong suction force so that the exhaust pipe 23 can send the waste gas generated externally into the interior of the preliminary filter box 2 through the air supply pipe 24.

[0028] like Figures 1 to 5 As shown, the air supply pipe 24 is located above the adsorption layer plate 51, the bottom of the secondary filter box 3 is set at a twenty-five degree angle, the bottom surface of the water storage tank 41 is fixedly connected to the center of the top surface of the bottom plate 1, and the two side surfaces of the water storage tank 41 are tightly fitted to the outer walls of the primary filter box 2 and the secondary filter box 3 respectively, and the top surface of the secondary filter box 3 is provided with a discharge pipe 31.

[0029] The above solution is adopted: an electromagnetic valve is arranged in the discharge pipe 31 to control the discharge of gas, and the electromagnetic valve belongs to the existing device and will not be elaborated in detail.

[0030] The working principle and use process of this utility model:

[0031] First, place the exhaust pipe 23 at the exhaust port of the metal processing device, and then start the air pump 22. The gas is transmitted to the air supply pipe 24 through the air pump 22 and then reaches the preliminary filter box 2. At this time, it is adsorbed and filtered once through the adsorption layer plate 51. When the gas continues to enter the preliminary filter box 2, two situations will occur. One is that the gas passes through the adsorption layer plate 51 and reaches the placement box 52. At this time, the activated carbon is adsorbed and purified again, and the other gas flows into the interior of the secondary filter box 3 through the through pipe 53. By starting the water pump 42, the water in the water tank 41 is extracted and transported to the circulation pipe 43, and then sprayed and atomized by the atomizing nozzle 45. After atomization spraying, the tiny particles in the exhaust gas come into contact with the water mist, and gradually gather and condense into larger particles under the action of condensation and wetting. They fall down with the action of gravity and pass through the small-aperture filter mesh 47 for one filtration, and the purified air flows out through the exhaust pipe 31.
