Description

Technical Field

[0001] The invention relates to the technical field of oil fume purification, and in particular to an oil fume purification device. Background Art

[0002] With the development of society and the improvement of people's living standards, people have higher and higher requirements for environmental hygiene and health. In the process of industrial processing, a large amount of industrial oil is used, which will produce a large amount of oil fume exhaust gas containing oil mist and oil fume particles. If it is directly discharged into the atmosphere, it will cause serious pollution to the environment. In order to reduce the pollution to the environment, it is necessary to use an oil fume purification device to filter and purify the oil fume.

[0003] When the oil fume purification device is used to filter and purify the oil fume, an oil filter plate is used inside the oil fume purification device to filter the oil mist in the oil fume, and the filtered oil mist falls on the surface of the oil filter plate and the oil filter holes. After the oil fume purification is completed, due to the viscosity of the oil, after the high-temperature oil fume gas is stopped from being introduced, the oil on the oil filter plate cools down, and the cooled oil solidifies and adheres to debris to seal the filter holes on the oil filter plate, resulting in the gas being unable to pass through the oil filter plate. When the oil fume is filtered and purified next time, the filter holes on the oil filter plate are sealed by the oil and debris, resulting in the gas inside the oil fume purification device being unable to pass through the oil filter plate. When cleaning with the scraper, the oil and debris in the oil filter holes on the oil filter plate cannot be processed, and the suction generated after the fan is started cannot pass through the oil filter plate, thereby failing to absorb the introduced oil fume gas, thereby reducing the flow rate of the oil fume in the oil fume purification device. Summary of the invention

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0027] Example 1: Reference Figure 1-5 A fume purification device includes a shell 1, one end of the shell 1 is provided with an air inlet, the other end of the shell 1 is provided with an air outlet, the air outlet is connected to a fan, the upper end of the shell 1 is detachably connected with a bucket-shaped open frame 2, the bottom end of the bucket-shaped open frame 2 is provided with an oil drain hole, both sides of the bucket-shaped open frame 2 are fixedly connected with oil filter plates 3, each oil filter plate 3 is inclined toward the oil drain hole, the bottom end of the shell 1 is provided with a through hole 4, the oil drain hole is located directly above the through hole 4, the bottom end of the shell 1 is detachably connected with a collection box 5 for collecting oil, the collection box 5 is connected with the through hole 4, the collection box 5 is a transparent collection box, the bucket-shaped open frame 2 is provided with an oil filter plate 3, and the oil filter plate 3 is provided with an oil filter plate 3. A movable plate 6 is slidably connected to the inner upper end of the opening frame 2, and a chamber is formed between the movable plate 6 and the bottom end of the bucket-shaped open frame 2. A heating plate is fixedly connected in the chamber. A spring is fixedly connected to the upper end of the movable plate 6, and one end of the spring is fixedly connected to the inner upper end of the bucket-shaped open frame 2. A plurality of springs are provided and distributed at the four corners of the movable plate 6. A dust-proof air inlet hole 7 is provided at the upper end of the bucket-shaped open frame 2. A motor 8 is fixedly connected to the inner upper end of the bucket-shaped open frame 2, and a cam 9 is fixedly connected to the output end of the motor 8, which can contact the upper end of the movable plate 6. An activated carbon purification net 10 is fixedly connected in the shell 1.

[0028] Working principle:

[0029] After the fan is started, suction is generated on the air inlet, and the generated suction absorbs the oil fume gas. The oil fume gas enters the housing 1 through the air inlet, and the oil fume gas entering the housing 1 contacts the oil filter plate 3, and the oil filter plate 3 filters the oil and impurities in the oil fume gas. The filtered oil fume gas contacts the activated carbon purification net 10, and the activated carbon purification net 10 removes the odor in the oil fume gas. The treated oil fume gas is released from the air outlet;

[0030] After the fume treatment is completed, the fan stops working, the heating plate is powered on and started, and the heating plate heats up after starting. Since the heating plate is in contact with the bucket-shaped open frame 2, the heat on the heating plate is transferred to the bucket-shaped open frame 2, and the heat on the bucket-shaped open frame 2 is transferred to the oil filter plate 3, so that the oil filter plate 3 is heated up. After the oil filter plate 3 is heated up, the solidified oil and debris on the oil filter plate 3 are softened due to the temperature increase, and the bonding strength between the oil, debris and the oil filter plate 3 is reduced. Since the oil filter plate 3 is inclined toward the oil discharge hole, the oil on the oil filter plate 3 The oil droplets and debris roll down to the bottom of the oil filter plate 3 along the length direction under their own gravity. After the oil and debris at the bottom of the oil filter plate 3 gradually increase, the volume of the oil droplets at the bottom of the oil filter plate 3 gradually increases. The oil droplets and debris at the bottom of the oil filter plate 3 fall under their own gravity and pass through the through hole 4 into the collecting box 5. The collecting box 5 collects the oil droplets and debris falling from the through hole 4, thereby reducing the residual oil and debris on the oil filter plate 3, reducing the obstruction of the filter holes on the oil filter plate 3 by the oil and debris, and maintaining the air permeability of the filter holes.

[0031] At the same time, the motor 8 is powered on and started. After the motor 8 is started, it drives the cam 9 to rotate. During the rotation of the cam 9, the movable plate 6 is continuously squeezed. After the convex position of the cam 9 contacts and squeezes the movable plate 6, the movable plate 6 is pressed and moves downward. After the movable plate 6 moves downward, the volume of the chamber decreases, and the pressure in the chamber increases, so that a part of the hot gas inside the chamber is released from the oil discharge hole, and another part of the hot gas is released from the oil filter hole on the oil filter plate 3. The hot gas released from the oil filter hole flushes the debris and oil droplets in the oil filter hole. The hot gas softens the debris and oil droplets on the oil filter hole, reduces the bonding strength between the debris, oil droplets and the oil filter hole, makes it easy to separate the debris and oil droplets from the oil filter hole, and avoids the debris and oil droplets from bonding in the oil filter hole. To ensure the air permeability and oil filtering effect of the oil filter hole, the sundries and oil droplets in the oil filter hole can be processed. At the same time, the movable plate 6 moves downward and pulls the spring. The spring generates elastic force after being pulled. After the convex position of the cam 9 is separated from the movable plate 6, the movable plate 6 is driven to move upward and reset under the action of the spring elastic force. After the movable plate 6 moves upward, the volume of the chamber increases, and the pressure inside the chamber decreases. A part of the gas in the shell 1 enters the chamber from the oil drain hole, and another part of the gas enters the chamber through the oil filter hole. When the gas enters the chamber from the oil filter hole, the oil filter hole is air-punched again. The oil droplets and sundries on the oil filter hole roll down along the inclined direction of the oil filter plate 3. The rolled oil droplets and sundries are released from the oil drain hole and enter the collection box 5, so that the oil droplets and sundries are separated from the oil drain hole, and the air permeability of the oil filter hole is maintained.

[0032] During the process of the cam 9 continuously squeezing the movable plate 6, the hot gas softens the debris and oil droplets on the oil filter hole, reducing the bonding strength between the debris, oil droplets and the oil filter hole. After the hot gas performs air-punching treatment on the oil droplets and debris on the oil filter hole, the debris and oil droplets are easily separated from the oil filter hole, avoiding the debris and oil droplets from adhering to the oil filter hole and not sealing the oil filter hole, thereby ensuring the air permeability and oil filtering effect of the oil filter hole, facilitating the gas in the shell 1 to pass through the oil filter hole, and processing the debris and oil droplets in the oil filter hole.

[0033] Embodiment 2: In embodiment 1, the movable plate 6 is pressed and then moves downward, and the hot gas softens the debris and oil droplets on the oil filter hole, reducing the bonding strength between the debris, oil droplets and the oil filter hole. The hot gas released from the oil filter hole performs air impact on the debris and oil droplets in the oil filter hole, making it easy for the debris and oil droplets to separate from the oil filter hole. The separated debris and oil droplets adhere to the inner wall of the shell 1 and the activated carbon purification net 10 under the impact of the gas. After being adhered to the inner wall of the shell 1, it is inconvenient to clean it. At the same time, after being adhered to the activated carbon purification net 10, the treatment effect of the activated carbon purification net 10 on the gas is reduced. Figure 6-8 As another preferred embodiment of the present invention, the difference from the embodiment 1 is that the motor 8 is connected with a liquid blocking and guiding mechanism 11 for preventing oil from splashing on the oil filter plate 3, and the liquid blocking and guiding mechanism 11 includes a reciprocating screw 111, which is fixedly connected to the output end of the motor 8, and the reciprocating screw 111 is connected with a threaded sleeve 112, and the threaded sleeve 112 is fixedly connected with connecting plates 113 on both opposite sides, and movable holes 114 are opened on both opposite sides of the bucket-shaped open frame 2, and one end of each connecting plate 113 passes through the corresponding Corresponding to the movable hole 114, one end of each connecting plate 113 is fixedly connected with a mounting plate 115, each mounting plate 115 is in contact with the bucket-shaped open frame 2, each mounting plate 115 covers and seals the corresponding movable hole 114, and the bottom end of each mounting plate 115 is connected with a plurality of scrapers 116 at equal intervals along the length direction, each scraper 116 is in contact with the oil filter plate 3, and an oil guide groove 117 is provided on one side of each scraper 116 close to the oil filter plate 3, and the bottom end of the oil guide groove 117 is located above the through hole 4.

[0034] Working principle:

[0035] Initially, a plurality of scrapers 116 cover the corresponding oil filter holes on the oil filter plate 3, and the oil guide groove 117 is connected to the oil filter holes. The output end of the motor 8 also drives the reciprocating screw 111 to rotate. After the reciprocating screw 111 rotates, the threaded sleeve 112 reciprocates along the length direction of the reciprocating screw 111. The threaded sleeve 112 drives the connecting plate 113 to move, the connecting plate 113 drives the mounting plate 115 to move, and the mounting plate 115 drives a plurality of scrapers 116 to move. During the movement of the scrapers 116, the surface of the oil filter plate 3 is scraped to reduce the residual oil on the surface of the oil filter plate 3.

[0036] When the raised position of the cam 9 contacts the movable plate 6 and squeezes the movable plate 6, the oil guide groove 117 is connected to the oil filter hole, and the hot gas impacts the debris and oil droplets in the oil filter hole. The impacted debris and oil droplets fall into the oil guide groove 117, and the hot gas that passes through the oil filter hole enters the oil guide groove 117. The debris and oil droplets in the oil guide groove 117 fall downward under the impact of their own gravity and the hot gas, and are released from the bottom of the oil guide groove 117. The liquid droplets pass through the through hole 4 and enter the collecting box 5, and the hot gas in the oil guide groove 117 passes through the through hole 4 to impact the oil in the collecting box 5. When the movable plate 6 moves downward to impact the debris and oil droplets in the oil filter hole, the separated debris and oil droplets fall into the oil guide groove 117 under the obstruction of the scraper 116, and the debris and oil droplets will not adhere to the inner wall of the housing 1 and the activated carbon purification net 10, thereby not reducing the treatment effect of the activated carbon purification net 10 on the oil fume gas;

[0037] After the raised position of the cam 9 is separated from the movable plate 6, the moving scraper 116 gradually becomes misaligned with the oil filter hole, and the threaded sleeve 112 continues to move along the length direction of the reciprocating screw 111. The threaded sleeve 112 changes its moving direction after moving to the end of the reciprocating screw 111. When the raised position of the cam 9 contacts the movable plate 6 again, the scraper 116 has covered the oil filter hole. Each time the raised position of the cam 9 squeezes the movable plate 6 to move downward, the scraper 116 covers the oil filter hole, effectively preventing the separated debris and oil droplets from contacting the activated carbon purification net 10, thereby not reducing the treatment effect of the activated carbon purification net 10 on the oil fume gas.

[0038] Embodiment 3: In embodiment 2, the hot gas passing through the oil filter hole enters the oil guide groove 117, and the debris and oil droplets in the oil guide groove 117 fall downward under the impact of their own gravity and the hot gas, and are released from the bottom of the oil guide groove 117. The released debris and oil droplets pass through the through hole 4 and enter the collection box 5. The hot gas in the oil guide groove 117 passes through the through hole 4 and impacts the oil in the collection box 5. When the oil in the collection box 5 has a certain height, the gas released from the bottom of the oil guide groove 117 impacts the oil in the collection box 5, which easily causes the oil in the collection box 5 to splash. Figure 9-10As another preferred embodiment of the present invention, the difference from Embodiment 2 is that the bottom ends of the scrapers 116 on both sides are fixedly connected with a reversing mechanism 12 for gas reversing, and the reversing mechanism 12 includes an arc-shaped collecting frame 122, and the upper end of the arc-shaped collecting frame 122 is connected with a plurality of groove plates 121 at equal intervals along the length direction, each groove plate 121 is connected to the bottom end of the corresponding scraper 116, and each groove plate 121 is connected to the corresponding oil guide groove 117, and a strip groove 123 is provided at the bottom end of the arc-shaped collecting frame 122, and the strip groove 123 is located above the through hole 4, and the grooves on the groove plate 121 are staggered with the strip groove 123, and an exhaust hole is provided at the upper end of the arc-shaped collecting frame 122, and the exhaust hole is connected with an air guide pipe 124, and the outlet end of the air guide pipe 124 is horizontally arranged toward the oil drain hole.

[0039] Working principle:

[0040] The hot gas, debris and oil droplets released from the bottom of the oil guide groove 117 pass through the grooves on the groove plate 121 and enter the arc-shaped collecting rack 122. Since the bottom end of the arc-shaped collecting rack 122 is an arc structure, the grooves on the groove plate 121 and the strip grooves 123 are staggered. The hot gas entering the arc-shaped collecting rack 122 collides with the bottom end of the arc-shaped collecting rack 122 and decelerates. The debris and oil droplets pass through the strip grooves 123 and fall into the collecting box 5. A part of the decelerated gas in the arc-shaped collecting rack 122 is released from the strip grooves 123, and the other part of the gas passes through the exhaust hole and enters the air guide pipe 124. The gas release direction in the air guide pipe 124 is parallel to the inner bottom end of the shell 1, thereby reducing the impact strength on the oil in the collecting box 5, and thus will not cause the oil in the collecting box 5 to splash.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
