Abstract
Description
Technical Field
[0001] This utility model relates to the field of pigment processing technology, specifically a filtration device for pigment production and processing. Background Technology
[0002] Pigments are substances that can color objects. They are mainly used in industries such as coatings, inks, printing and dyeing, plastic products, papermaking, rubber products, and ceramics. With the rapid development of downstream industries, the demand for pigments is constantly expanding, and the development prospects of China's pigment industry are very broad.
[0003] After raw material screening, the pigment raw materials need to be pulverized. The main purpose of this step is to minimize the particle size of the raw materials for subsequent processing. During this stage, technicians need to master appropriate process parameters, such as temperature and rotation speed, to ensure pigment quality. Inconsistent particle size and pigment powder impurities often affect pigment quality during preparation. Therefore, screening for substandard substances in the pigment is crucial during the filtration stage. A common screening method is using a vibrating screen. However, traditional vibrating screens, due to their small sieving amplitude, easily accumulate excessive pigment on their surface or bottom, potentially causing blockages and further impacting the speed and quality of pigment production.
[0004] Therefore, we propose a filtration device for pigment production and processing. Utility Model Content
[0005] The purpose of this invention is to provide a filtration device for pigment production and processing to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for pigment production and processing, comprising a processing box, a sieving assembly, the sieving assembly being installed inside the processing box, the sieving assembly including a mounting ring placed inside the processing box, two guide cylinders fixedly connected to the outer surface of the processing box, guide blocks being snapped into the interior of each of the two guide cylinders, and one end of each of the guide blocks being fixedly connected to the outer surface of the mounting ring, a filter screen plate being fixedly connected to the inner ring of the mounting ring, a fixed ball being fixedly connected to the upper surface of the mounting ring, a rotating column being installed inside the processing box, a fixed cylinder being fixedly connected to the upper surface of the outer surface of the rotating column, four sets of rotating rods arranged in a circular pattern being fixedly connected to the outer surface of the fixed cylinder, a fixed block being fixedly connected to the upper surface of each set of rotating rods located at the bottom, the position of the fixed block corresponding to the position of the fixed ball, and an auxiliary assembly installed above the interior of the processing box.
[0007] Preferably, each guide block is fixedly connected to the top wall of the guide cylinder with an elastic steel plate, which can provide power for the reset of the mounting ring and filter screen through the elastic force of the steel plate, thus preventing the device from jamming.
[0008] Preferably, the cross-sectional shape of the fixing block is trapezoidal, which allows the inclined surface of the fixing block to collide with the fixing ball, further making the fixed ball rise more smoothly.
[0009] Preferably, a drive motor is fixedly connected to the bottom wall of the processing box, and the top end of the output shaft of the drive motor is fixedly connected to the bottom surface of the rotating column, which can provide power for the rotation of the rotating column.
[0010] Preferably, a protective cover is fixedly connected to the bottom wall of the processing box, and the upper surface of the protective cover is rotatably connected to the output shaft of the drive motor through a bearing, which can prevent pigment powder from damaging the drive motor.
[0011] Preferably, the auxiliary component includes four scrapers. Each scraper has a set of guide rods fixedly connected to its upper surface. Each set of guide rods is engaged with a corresponding rotating rod. A set of springs is fixedly connected between the upper surface of each scraper and its corresponding rotating rod. Each spring is sleeved with its corresponding guide rod.
[0012] Preferably, each set of rotating rods has a uniformly distributed thin rod fixedly connected between the adjacent sides, which can break up clumps of pigment faster.
[0013] This utility model has at least the following beneficial effects:
[0014] 1. When sieving the pulverized pigment is required, first open the top cover of the processing box and place the pigment directly inside. Then close the top cover and turn on the power switch connected to the drive motor to rotate the output shaft of the drive motor. This will cause the rotating column, which is fixedly connected to the output shaft of the drive motor, to rotate synchronously. When the rotating column rotates, the fixed cylinder, which is fixedly connected to the rotating column, will also cause the rotating column, which is fixedly connected to the outer surface of the fixed cylinder, to rotate synchronously. At this time, the fixed block, which is fixedly installed on the lower rotating rod, will collide with the lower surface of the fixed ball. The collision occurs through the inclined surface of the fixed ball and the fixed block. The collision will lift the fixed ball and the mounting ring. Then, through the gravity of the mounting ring and the filter screen itself, and the guiding effect of the guide block and guide cylinder, the mounting ring can move up and down stably. The elastic steel plate can assist the mounting ring and the filter screen to automatically reset. At this time, the filter screen can vibrate more significantly than traditional methods, which can cause the pigment to adhere to the surface of the filter screen. This can further achieve the effect of screening and filtering the pigment that falls on the surface of the filter screen. The thin rod can break up the clumps of pigment during the vibration screening of the filter screen, which can further speed up the pigment screening process.
[0015] By setting up a screening component, a larger vibration amplitude can be achieved compared to a traditional vibrating screen, which can greatly reduce the probability of pigment adhering to the surface of the filter screen.
[0016] 2. While the rotating rod is providing power for the vibration of the filter screen, the scraper, under the elastic force of the spring and the guidance of the guide rod, allows the rotating rod to rotate while the scraper scrapes against the surface of the filter screen. This further loosens the pigment adhering to the surface of the filter screen. Then, through the vibration of the filter screen, the loosened pigment can more easily enter the area below the filter screen, further improving the overall efficiency of the device.
[0017] By setting auxiliary components, the screening components can be assisted in their operation, which can more effectively prevent pigment from adhering to the surface of the filter screen and avoid filter screen blockage during operation. This solves the problem that traditional vibrating screens, when screening pigments, are prone to excessive pigment adhering to their surface or bottom due to the small screening amplitude, which can even cause blockage of the vibrating screen and further affect the speed and quality of pigment production.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-5 This utility model provides a technical solution:
[0026] Example 1: A filtration device for pigment production and processing includes a processing box 3, a screening component 1, and a screening component 1 installed inside the processing box 3. The screening component 1 includes a mounting ring 6, which is placed inside the processing box 3. Two guide cylinders 4 are fixedly connected to the outer surface of the processing box 3. Guide blocks 5 are snapped into the interior of each of the two guide cylinders 4. One end of each guide block 5 inside the processing box 3 is fixedly connected to the outer surface of the mounting ring 6. A filter screen plate 7 is fixedly connected to the inner ring of the mounting ring 6. A fixed ball 9 is fixedly connected to the upper surface of the mounting ring 6. A rotating column 10 is installed inside the processing box 3. A fixed cylinder 13 is fixedly connected to the upper surface of the outer surface of the rotating column 10. Four sets of rotating rods 11 arranged in a circular pattern are fixedly connected to the outer surface of the fixed cylinder 13. A fixed block 12 is fixedly connected to the upper surface of each set of lower rotating rods 11. The position of the fixed block 12 corresponds to the position of the fixed ball 9. An auxiliary component 2 is installed above the interior of the processing box 3.
[0027] Each guide block 5 is fixedly connected to the top wall of the guide cylinder 4 with an elastic steel plate 8. The elasticity of the elastic steel plate 8 can provide power for the reset of the mounting ring 6 and the filter screen 7, thus preventing the device from jamming.
[0028] The fixed block 12 has a trapezoidal cross-sectional shape, which allows the inclined surface of the fixed block 12 to collide with the fixed ball 9, further making the fixed ball 9 rise more smoothly.
[0029] A drive motor 15 is fixedly connected to the bottom wall of the processing box 3. The top end of the output shaft of the drive motor 15 is fixedly connected to the bottom surface of the rotating column 10, which can provide power for the rotation of the rotating column 10.
[0030] A protective cover 16 is fixedly connected to the bottom wall of the processing box 3. The upper surface of the protective cover 16 is rotatably connected to the output shaft of the drive motor 15 through a bearing, which can prevent pigment powder from damaging the drive motor 15.
[0031] When the pulverized pigment needs to be sieved, first open the top cover of the processing box 3 and put the pigment directly into the processing box 3. Then close the top cover of the processing box 3. At this time, turn on the power switch that is electrically connected to the drive motor 15 to make the output shaft of the drive motor 15 rotate. This will drive the rotating column 10, which is fixedly connected to the output shaft of the drive motor 15, to rotate synchronously. When the rotating column 10 rotates, the fixed cylinder 13, which is fixedly connected to the rotating column 10, will drive the rotating column 10, which is fixedly connected to the outer surface of the fixed cylinder 13, to rotate synchronously. At this time, the fixed block 12, which is fixedly installed on the lower rotating rod 11, will collide with the lower part of the outer surface of the fixed ball 9. Through the interaction between the fixed ball 9 and the fixed block 12, the rotation of the fixed column 10 will be accelerated. The collision of the inclined surfaces will lift the fixed ball 9 and the mounting ring 6. Then, through the influence of the gravity of the mounting ring 6 and the filter screen 7, and the guiding effect of the guide block 5 and the guide cylinder 4, the mounting ring 6 can move up and down stably. The elastic steel plate 8 can assist the mounting ring 6 and the filter screen 7 to automatically reset. At this time, the filter screen 7 can vibrate more significantly than traditional methods, which can cause the pigment to adhere to the surface of the filter screen 7. This can further achieve the effect of screening and filtering the pigment that falls on the surface of the filter screen 7. The thin rod 14 can break up the clumps of pigment when the filter screen 7 vibrates and screens, which can further speed up the screening and filtering of pigment.
[0032] By setting the screening component 1, a larger vibration amplitude can be achieved compared to the traditional vibrating screen, which can greatly reduce the probability of pigment adhering to the surface of the filter screen 7.
[0033] In embodiment 2, the auxiliary component 2 includes a scraper 19, of which there are four scrapers 19. Each scraper 19 has a set of guide rods 17 fixedly connected to its upper surface. Each set of guide rods 17 is engaged with its corresponding rotating rod 11. Each scraper 19 has a set of springs 18 fixedly connected between its upper surface and its corresponding rotating rod 11. Each spring 18 is sleeved with its corresponding guide rod 17.
[0034] Each set of rotating rods 11 has a uniformly distributed thin rod 14 fixedly connected between the adjacent sides, which can break up clumps of pigment faster.
[0035] While the rotating rod 11 is rotating to provide power for the vibration of the filter screen plate 7, the scraper 19, under the elastic force of the spring 18 and the guidance of the guide rod 17, allows the rotating rod 11 to rotate while the scraper 19 scrapes against the surface of the filter screen plate 7. This further loosens the pigment adhering to the surface of the filter screen plate 7. Then, through the vibration of the filter screen plate 7, the loosened pigment can more easily enter the lower part of the filter screen plate 7, further improving the overall working efficiency of the device.
[0036] By setting auxiliary component 2, the screening component 1 can be assisted in its operation, which can more effectively avoid the problem of pigment adhering to the surface of the filter screen 7. It can also effectively prevent the filter screen 7 from clogging during the operation of the device. This solves the problem that when traditional vibrating screens screen pigments, the surface or bottom surface is easily contaminated with too much pigment due to the small screening amplitude, which can even cause the vibrating screen to clog and further affect the speed and quality of pigment production.
