Description

Technical Field

[0001] This utility model relates to the field of filtration in the production of nitrocellulose lacquer thinner, specifically a filtration device for the production of nitrocellulose lacquer thinner. Background Technology

[0002] Nitrocellulose lacquer thinner is a type of thinner formulated from organic solvents such as esters, alcohols, ketones, and benzenes. Nitrocellulose lacquer thinner can be used to thin nitrocellulose varnish, enamel, and primer. It can also be used as a thinner for nitrocellulose lacquer and primer with less stringent requirements, or for cleaning tools used in nitrocellulose lacquer application.

[0003] A Chinese patent with publication number CN214861561U discloses a filtration device for producing nitrocellulose lacquer thinner, including a base and a filtration module slidably connected to the base. The filtration module includes a housing slidably connected to the base, with a feed pump fixedly installed at one end of the housing. The feed pump is connected to a filter chamber located within the housing, and a rotating filter structure is installed within the filter chamber. A residue recovery module is also located within the housing, including a rotating partition structure and a guide chamber. The rotating partition structure is located at one end of the guide chamber, and one side of the rotating partition structure is connected to the filter chamber. The guide chamber is connected to a residual liquid collection tank movably installed within the housing, which performs secondary separation and collection of the filtered impurities, facilitating material conservation while completing the impurity collection operation.

[0004] However, the above-mentioned device still has some problems. For example, during the use of the device, the filtered impurities will pass through the filter plate. Over a long period of filtration, some impurities will clog the filter plate, making it difficult to clean and thus affecting the use of the device. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a filtration device for producing nitrocellulose lacquer thinner, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for producing nitrocellulose lacquer thinner, comprising a device body, a material guiding chamber, and a filter plate. A channel is provided within the device body, and an electronic push rod is fixedly installed within the channel. A material guiding plate is fixedly installed at the top of the electronic push rod. An impact plate is slidably installed within the device body, and a rotating rod is rotatably installed at the bottom of the impact plate. A blocking block is fixedly installed within the device body. A long rod is fixedly installed on the side wall of the material guiding plate. A through groove is provided within the device body, and a spring is installed within the through groove. A slider is fixedly installed within the device body.

[0007] By adopting the above technical solution, when the electronic push rod is activated, it drives the guide plate to move downward. During the downward movement of the guide plate, the first set of long rods at the bottom will first contact the rotating rod. The end of the rotating rod that contacts the long rod moves downward, causing the other end of the rotating rod to move upward. The upward end is blocked by the blocking block, which causes the entire impact plate to move downward and compress the spring. When the first set of long rods passes the rotating rod, the rotating rod loses its thrust, the spring rebounds, and the impact plate hits the bottom of the filter plate, causing the filter plate to vibrate. Then the second set of long rods contacts the rotating rod, forcing the end of the rotating rod that contacts the long rod to move downward. This process is repeated until the guide plate completely passes the rotating rod, causing the filter plate to vibrate multiple times and shaking off the impurities blocked in the gaps of the filter plate.

[0008] Furthermore, the slider is installed inside the channel, and the side of the slider away from the electronic push rod is designed to be inclined.

[0009] By adopting the above technical solution, impurities are easier to collect without affecting the electronic actuator.

[0010] Furthermore, one side of the outer wall of the rotating rod is located below the blocking block, and the other side of the outer wall of the rotating rod is located below the long rod, and multiple sets of rotating rods are installed at equal intervals at the bottom of the impact plate.

[0011] By adopting the above technical solution, the impact plate can be slid by rotating the rod through the long rod.

[0012] Furthermore, the impact plate is located below the filter plate, and the thickness of the impact plate is less than the thickness of the filter plate, and the outer wall of the impact plate is provided with protrusions located in the through groove.

[0013] By adopting the above technical solution, when the impact plate slides downward, the spring is compressed by the protrusion to store force, and the impact plate impacts the filter plate through the spring.

[0014] Furthermore, multiple sets of springs are installed at equal intervals in the through groove, and one end of the spring is connected to the bottom end of the protrusion on the outer wall of the impact plate, while the other end of the spring is fixedly connected to the outer wall of the through groove.

[0015] By adopting the above technical solution, the impact plate generates sufficient impact force by compressing the spring, causing the filter plate to vibrate.

[0016] Furthermore, the top of the guide plate is designed with a slope, and a slot is opened at the bottom of the side of the guide plate near the impact plate, and multiple sets of long rods are installed in the slot at equal intervals.

[0017] By adopting the above technical solution, multiple sets of long rods trigger the impact plate to strike the filter plate multiple times, further shaking off impurities from the filter plate.

[0018] In summary, the present invention has the following main advantages:

[0019] This invention comprises an electronic push rod, a long rod, a guide plate, an impact plate, a rotating rod, a spring, and a blocking block. When the electronic push rod is activated, it drives the guide plate downward. During this downward movement, the first set of long rods at the bottom contacts the rotating rod. The end of the rotating rod in contact with the long rod moves downward, causing the other end of the rotating rod to move upward. This upward end is blocked by the blocking block, causing the entire impact plate to move downward and compress the spring. After the first set of long rods passes the rotating rod, the rotating rod loses its thrust, and the spring rebounds, causing the impact plate to strike the bottom of the filter plate, thus vibrating the filter plate. Then, the second set of long rods contacts the rotating rod, forcing the end of the rotating rod in contact with the long rod to move downward. This process repeats until the guide plate has completely passed the rotating rod, causing the filter plate to vibrate multiple times and shaking off impurities that are blocking the gaps in the filter plate.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] A filtration device for producing nitrocellulose lacquer thinner, such as Figure 1 - Figure 6 As shown, the device includes a main body 1, a feeding chamber 2, and a filter plate 3. A channel 5 is provided inside the main body 1, through which impurities are collected. An electronic push rod 4 is fixedly installed inside the channel 5, and a guide plate 401 is fixedly installed at the top of the electronic push rod 4. The guide plate 401 moves up and down via the electronic push rod 4. An impact plate 6 is slidably installed inside the main body 1, impacting the filter plate 3. A rotating rod 601 is rotatably installed at the bottom of the impact plate 6. A filter plate 3 is fixed inside the main body 1. A blocking block 103 is installed, and a long rod 402 is fixedly installed on the side wall of the guide plate 401. The long rod 402 presses down on the rotating rod 601, and the rotating rod 601 is blocked by the blocking block 103, thereby driving the impact plate 6. A through groove 102 is opened in the main body 1 of the device, and a spring 7 is installed in the through groove 102. The impact plate 6 slides down and presses the spring 7. The spring 7 rebounds and causes the impact plate 6 to impact. A slider 101 is fixedly installed in the main body 1 of the device. Impurities fall onto the slider 101 and are collected.

[0030] Please see Figure 2 and Figure 3 The slider 101 is installed in the channel 5, and the side of the slider 101 away from the electronic push rod 4 is designed to be inclined. When the impurities fall onto the slider 101 during the falling process, they are guided by the inclined surface of the slider 101 into the collection channel 5, making it easier to collect the impurities without affecting the electronic push rod 4.

[0031] Please see Figure 3 , Figure 4 and Figure 6 One side of the outer wall of the rotating rod 601 is located below the blocking block 103, and the other side of the outer wall of the rotating rod 601 is located below the long rod 402. Multiple sets of rotating rods 601 are installed at equal intervals at the bottom of the impact plate 6. When the long rod 402 moves downward, it will compress the rotating rod 601 to rotate, thereby causing the side below the blocking block 103 to rotate upward. The side below the blocking block 103 is blocked by the blocking block 103, causing the rotating rod 601 to pull the impact plate 6 to slide downward. This allows the rotating rod 601 to drive the impact plate 6 to slide through the long rod 402.

[0032] Please see Figure 2 , Figure 3 , Figure 4 and Figure 6 The impact plate 6 is located below the filter plate 3, and the thickness of the impact plate 6 is less than the thickness of the filter plate 3. The outer wall of the impact plate 6 is provided with a protrusion located in the through groove 102. When the impact plate 6 slides down, the spring 7 is compressed by the protrusion to store force, and the impact plate 6 impacts the filter plate 3 by the spring 7.

[0033] Please see Figure 4 Multiple sets of springs 7 are installed at equal intervals in the through groove 102. One end of the spring 7 is connected to the bottom end of the protrusion on the outer wall of the impact plate 6, and the other end of the spring 7 is fixedly connected to the outer wall of the through groove 102. When the impact plate 6 slides downward, the protrusion will squeeze the spring 7 to make it begin to contract. When the force of the impact plate 6 sliding downward disappears, the spring 7 will rebound and make the impact plate 6 impact the filter plate 3 upward. This allows the impact plate 6 to generate sufficient impact force by squeezing the spring 7, causing the filter plate 3 to vibrate.

[0034] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 The top of the guide plate 401 is designed with a slope, and a slot is opened at the bottom of the side of the guide plate 401 near the impact plate 6. Multiple sets of long rods 402 are installed in the slot at equal intervals. Impurities slide through the top of the guide plate 401 and are filtered and intercepted by the filter plate 3. The guide plate 401 slides down through the electronic push rod 4, which can cause the multiple sets of long rods 402 to trigger the impact plate 6 to impact the filter plate 3 multiple times, further causing the filter plate 3 to shake off the impurities.

[0035] The working principle of this utility model is as follows: When the electronic push rod 4 is activated, a guide plate 401 is fixedly installed at the top of the electronic push rod 4. The guide plate 401 will slide downward with the electronic push rod 4. During the sliding process, the first set of long rods 402 at the bottom of the guide plate 401 will contact the top of one side of the rotating rod 601. The long rods 402 will push one side of the rotating rod 601 to move downward. Since the rotating rod 601 is rotatably installed at the bottom of the impact plate 6, the other side of the rotating rod 601 will move upward. Since a blocking block 103 is installed above the rotating rod 601, the blocking block 103 will block the upward movement of the rotating rod 601, thereby forcing the rotating rod 601 to drive the impact plate 6 to slide downward. The outer wall of the impact plate 6 is connected to multiple sets of springs 7 in the through groove 102. At this time, the impact plate 6 will squeeze the springs 7, and the springs 7 will absorb the pressure and contract. When the long rod 402 passes through the rotating rod 601, the rotating rod 601 loses its thrust, and the springs 7 release the pressure and begin to rebound, causing the impact plate 6 to slide in the opposite direction. Since the impact plate 6 is installed at the bottom of the filter plate 3, the impact plate 6 will hit the filter plate 3, causing the filter plate 3 to vibrate. Then the second set of long rods 402 will contact the reset rotating rod 601 again, causing the impact plate 6 to slide, reset and hit again until the guide plate 401 completely passes through the rotating rod 601. During this process, the impact plate 6 will hit the filter plate 3 multiple times, further causing the impurities blocking the filter plate 3 to be shaken off.
