Description

Technical Field

[0001] This utility model relates to the field of cat litter production screening technology, specifically a particle screening device for cat litter production. Background Technology

[0002] Phosphogypsum is a major industrial byproduct generated during the wet process of phosphoric acid production. For every ton of phosphoric acid produced, approximately 4-5 tons of phosphogypsum are generated. Its main component is calcium sulfate dihydrate. For a long time, phosphogypsum has been disposed of by stockpiling, which not only occupies a large amount of land resources, but may also lead to impurities being leached by rainwater. Current explorations of utilization pathways include blending into building materials and soil conditioners. The booming cat litter market provides a new direction for the high-value utilization of phosphogypsum. Phosphogypsum's naturally porous structure and water absorption make it inherently suitable for cat litter raw materials. After modification, it can achieve a closed-loop environmentally friendly process of "use-waste-soil improvement," becoming a highly promising resource utilization pathway. Existing cat litter generally uses pulp broken into small granules to simulate sand and provide water absorption. Some also use granules made with physical desiccants such as silica gel. During the production and granulation process of cat litter, it is necessary to screen the cat litter to separate the unformed cat litter raw material powder from the granules, in order to reduce the disease caused by cats inhaling fine dust into their lungs. However, after long-term use, the screens of cat litter are easily clogged by cat litter particles, making it inconvenient to clean or replace them. Furthermore, the flowability of cat litter can easily clog the hopper during storage and feeding, making continuous feeding difficult and inconvenient to use. Utility Model Content

[0003] The purpose of this invention is to provide a granular screening device for cat litter production, so as to solve the problems mentioned in the background art, such as easy clogging and inconvenience in cleaning and replacing the screen during material feeding.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a particle screening device for cat litter production, comprising an adjustable support base frame, the adjustable support base frame being a stepped design, and springs being symmetrically fixedly installed on both sides of the top surface of the adjustable support base frame, a storage tank being fixedly installed at one end of each spring, the bottom surface of the storage tank being inclined, and a screening tank being fixedly installed on one side of the storage tank, the end of the screening tank away from the storage tank being inclined, a filter screen being inserted and installed inside the screening tank, and tightening screws being evenly arranged on the bottom surface of the screening tank, the side of the filter screen being embedded in the bottom surface of the screening tank by tightening screws.

[0005] Preferably, one side of the bottom of the screening tank is fixedly installed with one end of the filter tank, and the other end of the filter tank extends to the other side of the screening tank and is fixedly installed. The bottom surface of the filter tank is inclined towards the discharge direction. The bottom surfaces of the filter tank and the screening tank are respectively provided with discharge ports, and cloth tubes are tied and fixed to the discharge ports of the screening tank and the filter tank. A holding trolley is placed at the end of the filter tank and the screening tank near the cloth tube.

[0006] Using the above technical solution, the finer cat litter can be collected through the filter tank, and the inclined design of the filter tank allows the cat litter to move to the other end and be discharged outwards. The use of the cloth tube can effectively reduce the cat litter from scattering when it falls into the container cart, and the container cart can collect qualified and unqualified cat litter for convenient transportation.

[0007] Preferably, a shield is fitted onto the upper end of the screening tank, and the shield is inserted into the screening tank. A suction mechanism is provided between the screening tank and the filter tank.

[0008] By adopting the above technical solution, the cat litter material discharged through the storage tank can be blocked by the shield, so that the cat litter material will not splash around and pollute the environment or cause waste when it falls into the screening tank.

[0009] Preferably, the suction mechanism includes: a suction fan, which is fixedly installed on the side wall of the screening tank, and fixing bolts are installed through both sides of the screening tank. The fixing bolts are threadedly connected to the screening tank. An exhaust pipe is installed through one end of the screening tank near the storage tank, and the exhaust pipe is connected to the suction fan by a pipe. The exhaust pipe is connected to the filter tank.

[0010] By adopting the above technical solution, the shield can be effectively installed and disassembled by engaging the shield and the storage tank, and by screwing the fixing bolts into the storage tank. The use of the suction fan can effectively extract the dust generated during screening and prevent the dust from spreading. At the same time, the sucked-in dust is sent into the interior of the filter tank through the exhaust pipe so that the scattered dust can be recovered and collected, which greatly reduces the environmental pollution caused by the dust spreading and can also recover the dust to reduce waste.

[0011] Preferably, the storage tank has a discharge port on the side near the screening tank, and a material distribution plate is rotatably installed inside the discharge port. The material distribution plate is embedded inside the discharge port. A gearbox is fixedly installed on the side surface of the storage tank, and the gearbox is inserted into the rotating shaft of the material distribution plate.

[0012] By adopting the above technical solution, the rotation speed of the drive motor can be reduced by the gearbox, so that the material distribution plate can rotate at a uniform speed when the drive motor is rotating, and the cat litter stored in the storage tank can be discharged in a quantitative manner. This prevents the screening tank from causing incomplete screening due to excessive cat litter input, and greatly improves the quality of the screened cat litter.

[0013] Preferably, a drive motor is fixedly installed on the side surface of the gearbox, and the drive motor is plugged into the gearbox, and an eccentric block is rotatably installed at one end of the storage slot.

[0014] By using the above technical solution, the material distribution plate connected to the gearbox can rotate at a uniform speed through the use of a drive motor and a gearbox. This reduces the rotation speed of the material distribution plate and prevents it from rotating too fast. Furthermore, the vibration generated by the rotation of the eccentric block allows the storage tank, screening tank, and filter tank to vibrate synchronously, enabling the cat litter to be easily separated and discharged through vibration.

[0015] Preferably, an acceleration pulley assembly is fixedly installed between the eccentric block and the drive motor, and protective covers are fixedly installed on both sides of the storage slot, with the protective covers and the rotating shaft of the eccentric block being concentrically designed.

[0016] By adopting the above technical solution, the eccentric block can be rotated faster by using the accelerated pulley assembly, which further increases the overall vibration frequency of the screening device. The eccentric blocks exposed on both sides of the storage tank are protected by the protective cover, which improves the safety of personnel when the screening device is in operation.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the particle screening device for cat litter production: 1. After prolonged use, when the filter screen becomes clogged, the filter screen can be detached from the sieving tank by unscrewing the tightening screw. The filter screen can then be removed for cleaning. When sieving cat litter with different particle sizes, different sizes of filter screens can be replaced and fixed by tightening the screw, greatly improving the convenience of changing different sizes and cleaning the filter screen.

[0018] 2. When cat litter is put into the storage tank and the drive motor is started, the drive motor will drive the acceleration pulley assembly to rotate faster, so that the eccentric block connected to the acceleration pulley assembly can rotate faster. With the use of springs, the storage tank, screening tank and filter tank can vibrate synchronously. Through the synchronous vibration of the storage tank, screening tank and filter tank, the cat litter can be better screened and discharged outwards, and the cat litter will not clog inside the storage tank.

[0019] 3. The gearbox allows the distribution plate to rotate slowly, which, together with the vibration of the storage tank, enables the cat litter stored in the storage tank to be discharged quantitatively and continuously from the discharge port. This allows the cat litter to fall evenly and continuously into the screening tank, preventing incomplete screening due to excessive feeding. 4. When cat litter is discharged from the discharge port, a shield can be used to cover the discharged cat litter to prevent it from falling out of the storage tank. At the same time, the use of a suction fan can extract a small amount of floating cat litter dust and send air into the filter tank, so that the scattered cat litter dust can be recovered and discharged into the filter tank, reducing the chance of cat litter flying out of the storage tank and screening, and reducing dust pollution to the surrounding environment.

[0027] 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.

[0028] Please see Figure 1-6 This utility model provides a technical solution: a granule screening device for cat litter production, including an adjustable support base 1. The adjustable support base 1 has a stepped design, and springs 11 are symmetrically fixedly installed on both sides of the top surface of the adjustable support base 1. A storage tank 2 is fixedly installed at the upper end of the springs 11, and a screening tank 3 is fixedly installed on one side of the storage tank 2. The bottom of the screening tank 3 is fixedly installed to one end of a filter tank 4, and the other end of the filter tank 4 extends to the other side of the screening tank 3 and is then fixedly installed. The bottom surface of the filter tank 4 slopes towards the discharge direction. The filter tank 4 and the screening tank 3 are respectively provided with discharge ports on their bottom surfaces. The discharge ports of the screening tank 3 and the filter tank 4 are bound and fixed with cloth tubes 19. A holding cart 20 is placed at the end of the filter tank 4 and the screening tank 3 near the cloth tube 19. The end of the screening tank 3 away from the storage tank 2 is designed to be inclined. The bottom surface of the storage tank 2 is also designed to be inclined. A filter screen 5 is inserted and installed inside the screening tank 3. Tightening screws 6 are evenly arranged on the bottom surface of the screening tank 3. The side of the filter screen 5 is embedded in the bottom surface of the screening tank 3 by tightening screws 6.

[0029] First, when using the device, simply select the corresponding size filter screen 5 and install it into the sieving tank 3. Then, fix the filter screen 5 by tightening the screws 6. After putting the cat litter into the storage tank 2, start the drive motor 14 so that the storage tank 2, sieving tank 3, and filter tank 4 can reciprocate above the adjustable support base 1 due to the rotation of the eccentric block 17 and the use of the spring 11. The filter screen 5 can be flexibly switched to sieve different types of cat litter. After long-term use, the filter screen 5 can be removed for cleaning, which greatly improves the flexibility of the sieving device during use and the convenience of cleaning.

[0030] During screening, cat litter particles that are too small will fall through the filter screen 5 into the filter tank 4. Vibration will cause both qualified and unqualified cat litter to move within the screening tank 3 and filter tank 4, allowing the cat litter to be discharged into different collection carts 20. The cloth tube 19 will reduce the splashing of cat litter particles when they are discharged, further reducing the loss and waste of cat litter.

[0031] A shield 7 is fitted onto the upper end of the screening tank 3, and the shield 7 is inserted into the screening tank 3. A suction mechanism is provided between the screening tank 3 and the filter tank 4. The suction mechanism includes a suction fan 8, which is fixedly installed on the side wall of the screening tank 3. Fixing bolts 10 are installed through both sides of the screening tank 3, and the fixing bolts 10 are threadedly connected to the screening tank 3. An exhaust pipe 9 is installed through one end of the screening tank 3 near the storage tank 2, and the exhaust pipe 9 is connected to the suction fan 8 by a pipe. The exhaust pipe 9 is connected to the filter tank 4.

[0032] Secondly, when the material in storage tank 2 is vibrated and discharged into the screening tank 3, the shield 7 will block the splashed cat litter, and the dust drawn up by the suction fan 8 will be discharged into the filter tank 4 through the pipe and exhaust pipe 9, so that dust and particles will not fall around the wet screening device and cause environmental pollution. The shield 7 can be disassembled and installed by fixing bolts 10, which facilitates the subsequent installation and removal of the filter screen 5 and the cleaning of screening tank 3 and filter tank 4, which greatly reduces the dust generated during the use of the screening device and reduces the waste of cat litter material.

[0033] A discharge port 12 is provided on the side of the storage tank 2 near the screening tank 3, and a material distribution plate 15 is rotatably installed inside the discharge port 12. The material distribution plate 15 is embedded in the discharge port 12. A reduction gearbox 13 is fixedly installed on the side surface of the storage tank 2, and the reduction gearbox 13 is inserted into the rotating shaft of the material distribution plate 15. A drive motor 14 is fixedly installed on the side surface of the reduction gearbox 13, and the drive motor 14 is inserted into the reduction gearbox 13. An eccentric block 17 is rotatably installed at one end of the storage tank 2, and an acceleration pulley assembly 16 is fixedly installed between the eccentric block 17 and the drive motor 14. Protective covers 18 are fixedly installed on both sides of the storage tank 2, and the rotating shafts of the protective covers 18 and the eccentric block 17 are concentrically designed.

[0034] Furthermore, once the drive motor 14 starts, it will drive the reduction gearbox 13 and the acceleration pulley assembly 16 to work synchronously, allowing the eccentric block 17 to rotate faster. The protective cover 18 can prevent the eccentric block 17 from causing danger to the user. The distribution plate 15 can reduce the rotation speed. In conjunction with the vibration of the storage tank 2, the screening tank 3, and the filter tank 4, the cat litter can be continuously and quantitatively discharged from the discharge port 12. This ensures that when the screening tank 3 and the filter screen 5 are screening the cat litter, the screen will not be unevenly screened due to excessive cat litter discharge, greatly improving the screening quality of the screening device and increasing the vibration frequency.

[0035] Working principle: In use, simply pour cat litter into the storage tank 2 and start the drive motor 14. This will cause the reduction gearbox 13 and the acceleration pulley assembly 16 to rotate synchronously, allowing the eccentric block 17 to rotate faster and the distribution plate 15 to rotate slower. Through the rotation of the eccentric block 17 and the use of the spring 11, the storage tank 2, screening tank 3, and filter tank 4 can vibrate synchronously. This allows the storage tank 2 to gather the cat litter together with the vibration, reducing the chance of clumping. Simultaneously, the rotation of the distribution plate 15 distributes the cat litter... The litter can be discharged quantitatively from the storage tank 2. The discharged litter is blocked by the shield 7, and the dust is sucked up by the suction fan 8 and sent into the filter tank 4 through the exhaust pipe 9. The litter is moved by the vibration of the screening tank 3 and the filter tank 4 and screened by the filter screen 5. The litter that meets the requirements can be discharged into the holding cart 20 through one end of the screening tank 3, and the litter that does not meet the requirements can be discharged into the other holding cart 20 through the filter tank 4, thus completing the screening of the litter.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
