Description

Technical Field

[0001] The present invention relates to the technical field of oil mist purification, and more specifically, to a die-casting oil mist purifier. Background Art

[0002] The die-casting oil mist purifier is a device specially used to deal with the oil mist and smoke generated in the die-casting process. Its main purpose is to purify the air, remove harmful substances in the oil mist and smoke, and ensure the cleanliness and safety of the working environment. The oil mist purifier purifies the air through the pre-filter, several adsorption tubes inside it, and the post-filter in turn. Among them, the adsorption tube in the oil mist purifier can adsorb the oil mist particles in the air by static electricity or condensation, so that the oil mist particles are trapped on the inner wall of the adsorption tube. In order to increase the adsorption area between the adsorption tube and the oil mist, multiple adsorption tubes are usually set in the purifier. As soon as the adsorption tube starts to purify the air containing oil mist, grease will gradually accumulate on its inner wall. Once the adsorption tube is accumulated The accumulation will lead to a decrease in the adsorption effect of oil mist, causing part of the oil mist to pass through the adsorption tube and accumulate on the post-filter, causing the post-filter to be blocked. Moreover, since the oil mist is not necessarily evenly distributed in the air, the air does not necessarily pass through all the adsorption tubes evenly. Therefore, the amount of grease accumulation in all the adsorption tubes will be different, making it impossible for operators to predict the accumulation of grease in the adsorption tubes, causing some adsorption tubes to frequently accumulate grease during use. Even if grease accumulates in some adsorption tubes, it will affect the post-filter. Therefore, some adsorption tubes need to be cleaned separately, which will cause the purifier to be frequently disassembled and cleaned during use, thereby affecting the working efficiency of the purifier. Summary of the invention

[0003] In order to overcome the shortcomings mentioned in the above background technology, the present invention provides a die-casting oil mist purifier.

[0004] The technical solution of the present invention is: a die-casting oil mist purifier, comprising: A bracket, wherein the bracket is equipped with a purifier body, and a front filter, a rear filter and a fan are sequentially installed in the purifier body; A fixing frame, fixedly connected to the purifier body, the fixing frame is located between the front filter screen and the rear filter screen, and the fixing frame is fixedly connected to a plurality of adsorption tubes; The number of cleaning plates is the same as that of the adsorption tubes, and they are respectively slidably connected to adjacent adsorption tubes.

[0007] Further description, the transmission assembly includes: A gearbox is mounted on the purifier body, wherein the input shaft of the gearbox is fixedly connected to the fan, the output shaft of the gearbox is fixedly connected to a missing gear, the fixing frame is rotatably connected to a first gear that is matched with the missing gear, and a torsion spring is fixedly connected between the first gear and the fixing frame; A flexible rack is disposed on the fixed frame, and the first gear is meshed with the flexible rack; The second gear, the number of which is the same as the number of the adsorption tubes, is rotatably connected to the post-filter screen, the second gear is meshed with the flexible rack, and the second gear is transmitted to the adjacent guide rod through a transmission member.

[0008] To further illustrate, the number of teeth on the missing gear is A times the number of teeth on the second gear, the guide groove of the guide rod is threaded, the number of thread turns of the guide groove on the guide rod is B, and A=B.

[0009] Further explanation includes: The number of the collecting shells is twice that of the adsorption tubes, which are symmetrically distributed and respectively fixed to the two sides of the adjacent guide rods. The collecting shells symmetrically distributed on different sides are respectively located on the two sides of the adjacent adsorption tubes, and the collecting shells are rotatably connected to the adjacent adsorption tubes.

[0010] It is further explained that an elastic member is fixedly connected between the collecting shell and the adjacent cleaning member, and the cleaning member is slidably connected to the adjacent guide rod.

[0011] It is further explained that the inner cross-section of the collecting shell near the elastic member thereon gradually increases from close to the adjacent adsorption tube to far away from it.

[0012] It is further explained that the cleaning element is provided with circumferentially distributed scraper portions, and the scraper portions are in an inclined state.

[0013] Further explanation includes: The baffles, the number of which is half of the number of the collecting shells, are respectively slidably connected to the adjacent collecting shells on one side close to the pre-filter.

[0014] The beneficial effects of the above technical solution are as follows: 1. The present invention scrapes off the oil mist accumulated on the inner wall of the adsorption tube by the cleaning plate, without removing the adsorption tube, so that the grease in the adsorption tube is continuously scraped off during use, thereby avoiding frequent accumulation of grease in some adsorption tubes and causing the adsorption effect of the oil mist to gradually decrease, thereby reducing the disassembly and cleaning frequency of the purifier and ensuring the working efficiency of the purifier; 2.

[0018] In order to reduce the amount of grease accumulated on the inner wall of the adsorption tube and ensure the working efficiency of the oil mist purifier, such as Figure 1-Figure 7 As shown, the present invention proposes a die-cast oil mist purifier, comprising: a bracket 1, a control panel is installed on the bracket 1, a purifier body 2 is installed on the bracket 1, a pre-filter 201, a post-filter 202 and a fan 203 are sequentially installed in the purifier body 2, and the fan 203 is electrically connected to the control panel, wherein the pre-filter 201 is used to intercept and filter larger particles to reduce the clogging frequency of the post-filter 202, and the post-filter 202 is used to filter fine particles and absorb harmful substances in the air; a fixed frame 3, fixedly connected to the purifier body 2, the fixed frame 3 is located between the pre-filter 201 and the post-filter 202, and the fixed frame 3 is fixedly connected to a plurality of adsorption tubes 301, the adsorption tubes 301 can be connected to an external power supply, which is used to provide static electricity for all adsorption tubes 301, and adsorb oil mist particles in the air through static electricity, and the adsorption tubes 301 can also be connected to an external refrigeration device, so as to adsorb oil mist particles in the air through condensation; cleaning plates 4, the number of which is the same as that of the adsorption tubes 301. The number of the attached tubes 301 is the same, and they are respectively slidably connected to the adjacent adsorption tubes 301. A guide rod 401 with a guide groove is provided in the adsorption tube 301. The cleaning plate 4 is provided with a limiting portion that cooperates with the guide groove of the adjacent guide rod 401. The cleaning plate 4 slides back and forth on the adjacent guide rod 401 to scrape off the grease adhered to the inner wall of the adjacent adsorption tube 301. Cleaning members 402 are provided on both sides of the guide rod 401. In this embodiment, the cleaning member 402 and the adjacent guide rod 401 can be fixedly connected. The cleaning member 402 is used to impact the surface of the cleaning plate 4 so that the grease on the cleaning plate 4 is shaken off. The straight length of the guide groove on the guide rod 401 is X, the length of the adsorption tube 301 is Y, and the thickness of the cleaning plate 4 is Z, X>Y+Z, so that after the cleaning plate 4 moves to the extreme position on the front side or the rear side, there is a gap between the cleaning plate 4 and the adjacent adsorption tube 301; the transmission component 5 is arranged in the purifier body 2, and is used to transmit all the guide rods 401.

[0019] like Figure 3-Figure 5 and Figure 8As shown, the transmission assembly 5 includes: a gearbox 501, which is installed on the purifier body 2, the input shaft of the gearbox 501 is fixedly connected to the fan 203, and the output shaft of the gearbox 501 is fixedly connected to the missing gear 502. The gearbox 501 is used to reduce the speed of its input shaft and transmit it to the missing gear 502 through the output shaft. The fixed frame 3 is rotatably connected to a first gear 503 that is transmission-matched with the missing gear 502, and a torsion spring is fixedly connected between the first gear 503 and the fixed frame 3. After the missing gear 502 rotates to mesh with the first gear 503, the missing gear 502 rotates and drives the first gear 503 to rotate, so that the torsion spring of the first gear 503 rotates and accumulates force. After the missing gear 502 rotates to lose meshing with the first gear 503, the torsion spring drives the first gear 503 to rotate and reset; a flexible rack 5031 is embedded in the fixed frame 3, and can rotate on the fixed frame 3 with the missing gear 502 as the axis. The first gear 503 and the flexible rack 50 31 meshes, and the reciprocating rotation of the first gear 503 drives the flexible rack 5031 to reciprocate; the second gear 504, the number of which is the same as the number of the adsorption tubes 301, is rotatably connected to the post-filter 202, the second gear 504 is meshed with the flexible rack 5031, and the second gear 504 and the adjacent guide rod 401 are transmitted through a transmission member 505, wherein the transmission member 505 is composed of two pulleys and a belt, one of which is fixed to the guide rod 401, and the other pulley is coaxially connected to the second gear 504, the number of teeth on the missing gear 502 is A times the number of teeth on the second gear 504, the guide groove of the guide rod 401 is threaded, and the number of thread turns of the guide groove on the guide rod 401 is B, A=B, so that after the missing gear 502 rotates from the state of being meshed with the first gear 503 to losing meshing with the first gear 503, the cleaning plate 4 just moves from the rear side of the guide groove on the adjacent guide rod 401 to the front side.

[0020] Here’s how it works: When the operator needs to use the device to purify the oil mist generated during the die-casting operation, the operator installs the device at the required position and then turns on the fan 203 through the control panel. The fan 203 draws air from the purifier body 2, so that the air containing the oil mist passes through the pre-filter 201, several adsorption tubes 301 and the post-filter 202 in sequence and moves to the fan 203. The pre-filter 201 intercepts large particles, the adsorption tube 301 adsorbs the oil mist, and the post-filter 202 filters harmful substances. Then the clean air after purification is discharged through the fan 203.

[0021] During the use of the device, the oil mist is continuously accumulated on the inner wall of the adsorption tube 301, the rotating shaft of the fan 203 drives the missing gear 502 to rotate through the gearbox 501, the missing gear 502 drives the first gear 503 to make the first gear 503 reciprocate, the first gear 503 drives all the second gears 504 to reciprocate through the flexible rack 5031, the second gear 504 drives the guide rod 401 to reciprocate through the transmission member 505, the guide rod 401 reciprocates and drives the guide groove thereon to reciprocate and squeeze the limiting part of the cleaning plate 4 , so that the cleaning plate 4 moves back and forth, and the cleaning plate 4 scrapes off the oil mist accumulated on the inner wall of the adsorption tube 301, and when the cleaning plate 4 moves to collide with the adjacent cleaning member 402, the cleaning member 402 shakes off the grease adhered to the adjacent cleaning plate 4, and there is no need to remove the adsorption tube 301, so that the grease in the adsorption tube 301 is continuously scraped off during use, avoiding the accumulation of grease in part of the adsorption tube 301, which causes its adsorption effect on oil mist to gradually decrease, thereby reducing the disassembly and cleaning frequency of the purifier, and ensuring the working efficiency of the purifier.

[0022] When the operator needs to stop using the device, the operator turns off the fan 203 and then disassembles, cleans and maintains the device for the next use.

[0023] In the above-mentioned embodiment, the cleaning member 402 is fixedly connected to the adjacent guide rod 401 . In the following embodiment, the cleaning member 402 is slidably connected to the adjacent guide rod 401 .

[0024] In order to reduce the contact between air and grease accumulated in the purifier, Figure 5-Figure 7As shown, the present invention also includes: a collecting shell 6, the number of which is twice that of the adsorption tube 301, and two collecting shells 6 symmetrically distributed front and back are respectively fixed to the front and back sides of the adjacent guide rod 401, and the collecting shells 6 symmetrically distributed on the front and back sides are respectively located on the front and back sides of the adjacent adsorption tube 301, and the collecting shell 6 is rotatably connected to the adjacent adsorption tube 301, and an elastic member is fixed between the collecting shell 6 and the adjacent cleaning member 402, wherein the elastic member is a spring, and the cleaning member 402 is slidably connected to the adjacent guide rod 401, so that after the cleaning plate 4 moves to the vicinity of the adjacent collecting shell 6, the cleaning plate 4 squeezes the adjacent cleaning member 402 and compresses its elastic member, and the cleaning member 402 rotates and fits closely to the adjacent cleaning plate 4, thereby increasing the cleaning force of the cleaning member 402 on the adjacent cleaning plate 4, and the collecting shell The inner cross-section of the elastic member in the body 6 close to it gradually increases from close to the adjacent adsorption tube 301 to far away, so as to increase the collection space in the collection shell 6 and prevent the grease from flowing back out of the collection shell 6. The cleaning member 402 is provided with a circumferentially distributed scraper portion, which is in an inclined state, so as to guide the scraped grease into the collection shell 6. In the process of the missing gear 502 being engaged with the first gear 503, the cleaning plate 4 moves forward along the adjacent guide rod 401 to push the grease into the collection shell 6 on the front side. After the missing gear 502 loses engagement with the first gear 503, the torsion spring drives the first gear 503 to quickly reset, so that the cleaning plate 4 will also quickly reset to the rear side, blocking the collection shell 6 on the rear side, reducing the contact between air and the grease in the collection shell 6 on the rear side.

[0025] Here’s how it works: During the forward and backward movement of the cleaning plate 4, taking the backward movement of the cleaning plate 4 as an example, when the cleaning plate 4 moves to contact with the cleaning member 402, the cleaning plate 4 moves backward and squeezes the cleaning member 402, so that the elastic member of the cleaning member 402 gradually contracts, and the guide rod 401 drives the cleaning member 402 to rotate during the rotation process, and the cleaning member 402 scrapes the grease on the cleaning plate 4 through the scraper part thereon. The grease gradually accumulates on the cleaning plate 4 and moves backward along its scraper part, and then the grease is collected in the collecting shell 6. After the air passes through the adsorption tube 301, the air flows along the gap between the adsorption tube 301 and the cleaning plate 4 to the rear filter 202 to reduce the contact between the air and the accumulated grease in the purifier, thereby reducing the grease content in the air in contact with the rear filter 202, so as to reduce the probability of clogging of the rear filter 202 and ensure the stability of the use of the purifier.

[0026] In order to improve the convenience of cleaning the device and reduce the frequency of disassembly and assembly of the adsorption tube 301, as Fig. 9 As shown, the present invention further includes: baffles 7, the number of which is half of the number of the collecting shells 6, which are respectively slidably connected to the adjacent collecting shells 6 at the front side.

[0027] Here’s how it works: When the operator stops using the device, the operator turns off the fan 203, and the torsion spring of the first gear 503 drives it to rotate and reset, so that the missing gear 502 rotates and resets. At this time, the cleaning plate 4 is located at the rear cleaning member 402. Therefore, when the device is started to be used, the cleaning plate 4 moves forward first, and the air comes from the front side of the adsorption tube 301, which pushes more grease into the front collection shell 6. When the front collection shell 6 needs to be cleaned, the operator removes the pre-filter 201, and then manually pulls out the baffle 7 to clean the pre-filter 201 and the front collection shell 6. The grease in the device can be simply cleaned without disassembling the adsorption tube 301, thereby reducing the cleaning steps and reducing the frequency of disassembly and assembly of the adsorption tube 301, thereby improving the convenience of cleaning the device. Finally, the baffle 7 and the pre-filter 201 are installed back for the next use.

[0028] In summary, the invention includes but is not limited to the above embodiments. Any equivalent substitution or partial improvement made under the spirit and principle of the invention shall be deemed to be within the protection scope of the invention.
