Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment technology, specifically a resin washing device. Background Technology

[0002] Resin particles, as an important material in industrial production, are widely used in water treatment, chemical separation, and pharmaceutical purification. With the increasing demands on resin performance, the efficiency of impurity removal and operational stability during the washing process have become particularly important. A search revealed a resin particle washing device with publication number CN114425826B, published on March 26, 2024. This setup achieves effective impurity treatment of resin particles through a multi-layer tray structure. However, the tray structure of this device is relatively fixed, limiting its adaptability to resin particles of different sizes and shapes in practical applications, potentially leading to uneven washing results. Furthermore, the discharge port sealing door poses a risk of leakage during long-term operation, thus affecting overall washing efficiency and equipment lifespan. Utility Model Content

[0003] To address the aforementioned technical problems, this invention provides a resin washing device. This device, through optimized structural design, solves the problems of fixed tray structure, poor adaptability, and insufficient sealing performance of the discharge port in existing technologies. By improving core components, this invention achieves efficient washing of resin particles of different sizes and shapes, while avoiding potential leakage risks during long-term operation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A resin washing device, characterized in that it comprises the following components:

[0006] The washing chamber includes a chamber body and a top cover. The top cover is connected to the filling port on the top of the chamber body by a thread. A through hole is provided at the center of the top of the chamber body.

[0007] The rotary drive assembly includes a drive motor, a drive shaft, and a drive shaft. The drive shaft passes through a through hole, with its top end connected to the output end of the drive motor and its lower end extending into the cavity body and equipped with several stirring claws.

[0008] The layered filtration assembly includes multiple layers of filter screens disposed inside the cavity body, below the stirring claws. Each layer of filter screen has a different pore size to accommodate resin particles of different sizes.

[0009] The liquid storage tank is located next to the washing chamber. The inlet of the liquid storage tank is connected to the outlet of the main body of the chamber through a pipe, and the first outlet of the liquid storage tank is connected to a vacuum pump.

[0010] Preferably, the cavity body is further provided with a cleaning spray module located above the stirring claw, and the cleaning spray module is connected to the water inlet on the outer wall of the cavity body through a pipeline.

[0011] Preferably, the cleaning spray module is a fan-shaped spray structure, on which multiple nozzles are evenly distributed, and the nozzle directions form a fixed angle with the horizontal plane to form a spray water flow that covers the entire interior of the cavity.

[0012] Preferably, the stirring claws are arranged in a spiral shape, with a uniform gap between adjacent stirring claws, so as to form a dynamic stirring field during rotation.

[0013] Preferably, a sealing groove is provided at the top of the filling port, and a flexible sealing gasket is embedded in the sealing groove. The top cover is tightly fitted to the filling port by a threaded connection.

[0014] Preferably, a one-way valve is installed at the first outlet of the liquid storage tank to control the liquid flow direction.

[0015] Preferably, a manual shut-off valve is provided at the connection between the inlet of the liquid storage tank and the outlet of the cavity body to regulate the fluid flow rate.

[0016] Preferably, the top cover surface is provided with two symmetrical handles to facilitate disassembly and assembly by operators.

[0017] The connection relationships and working principles between the components in the technical solution adopted in this utility model are as follows:

[0018] The drive motor rotates the agitator claws via a transmission shaft. The agitator claws are arranged in a spiral pattern, generating a uniform stirring force during rotation. This ensures that the resin particles are fully agitated within the chamber, thereby improving washing efficiency. The agitator claws are connected to the transmission shaft via a keyway to ensure stability during rotation.

[0019] The cleaning spray module is connected to the water inlet via a pipeline. When an external water source is connected, the water flows through the nozzles to form a fan-shaped spray. The nozzle direction is precisely set so that the water flow can cover the entire cavity without directly impacting the resin particles, thus avoiding damage to the particles.

[0020] The layered filtration assembly is fixed inside the main chamber by a bracket. The pore size of each filter layer gradually decreases from top to bottom to accommodate resin particles of different sizes. The filter screens are connected to the bracket by snap-fit ​​connections for easy replacement and cleaning.

[0021] The storage tank is connected to the main body of the chamber via a pipe. The first outlet of the storage tank is connected to a vacuum pump for extracting liquid from the chamber. A one-way valve prevents backflow, while a manual shut-off valve allows the operator to adjust the flow rate as needed.

[0022] The top cover and the filling port are connected by threads. A sealing groove is provided on the top of the filling port, and a flexible sealing gasket is embedded in the sealing groove to ensure the sealing performance between the two. The threaded connection not only facilitates disassembly, but also can withstand high pressure.

[0023] This utility model has the following advantages due to the adoption of the above technical solution:

[0024] This invention solves the problem in existing technologies where the tray structure is fixed and cannot flexibly adapt to resin particles of different sizes and shapes by using a layered filtration assembly. The pore size of the layered filter screen changes progressively, effectively separating impurities while preventing resin particle clogging.

[0025] This utility model device improves the sealing structure between the top cover and the filling port by using a threaded connection with a flexible sealing gasket, which significantly improves the sealing performance and avoids leakage problems that may occur during long-term operation.

[0026] The fan-shaped spray structure of the cleaning spray module can achieve full coverage of the cavity. The water flow direction is optimized to ensure the washing effect while avoiding damage to the resin particles.

[0027] The spiral arrangement of the stirring claws, combined with the formation of a dynamic stirring field, allows the resin particles to be fully agitated during the washing process, thereby improving washing uniformity and efficiency.

[0028] The connection between the storage tank and the main body of the cavity is simple and reliable. The combination of a check valve and a manual shut-off valve further enhances the flexibility and safety of operation.

[0029] In summary, this utility model solves key problems existing in the prior art through a series of innovative designs, and has strong practicality and promotional value. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] The specific embodiments of this utility model's resin washing device are described in detail with reference to the accompanying drawings. For example... Figures 1 to 6As shown, this device includes a rotary drive assembly 1, a washing chamber 5, a stratified filtration assembly 9, and a liquid storage tank 11. The components cooperate through a specific connection method. Example 1

[0042] In this embodiment, the washing chamber 5 is composed of a chamber body 6 and a detachable top cover 7. The top cover 7 is connected to the filling port 51 on the top of the chamber body 6 by a thread. A sealing groove 18 is provided on the top of the filling port 51. A flexible sealing gasket 19 is embedded in the sealing groove 18 to ensure the sealing performance between the two. Two symmetrical handles 20 are also provided on the surface of the top cover 7 to facilitate disassembly and assembly by the operator. A through hole 8 is provided in the center of the top of the chamber body 6.

[0043] Based on Embodiment 1, the rotary drive assembly 1 includes a drive motor 2, a transmission shaft 3, and stirring claws 4. The drive motor 2 is fixedly mounted on the top of the washing chamber 5 and transmits power to the transmission shaft 3 via a keyway connection. The transmission shaft 3 extends vertically through a through hole 8 in the center of the top cover 7 into the interior of the chamber body 6. The stirring claws 4 are mounted on the lower end of the transmission shaft 3 and are arranged in a spiral shape with uniform gaps between adjacent stirring claws 4. The spiral arrangement of the stirring claws 4 allows them to form a dynamic stirring field during rotation, thereby agitating the resin particles inside the chamber body 6. The stirring claws 4 are fixedly connected to the transmission shaft 3 with bolts to ensure stability during operation. When resin washing is required, the user holds the handle 20 and rotates to open the top cover 7, then places the resin particles to be washed into the chamber body 6, and simultaneously starts the drive motor 2. The output end of the drive motor 2 drives the transmission shaft 3 to rotate, and the stirring claws 4 at the lower end of the transmission shaft 3 rotate and agitate the resin particles. Example 2

[0044] It should be noted that the main body 6 of the cavity contains a layered filter assembly 9 and a cleaning spray module 13. The layered filter assembly 9 is located below the stirring claw 4 and is fixed to the inner wall of the main body 6 by a bracket. The layered filter assembly 9 includes multiple layers of filter screens 10, with the pore size of each layer of filter screen 10 gradually decreasing from top to bottom to accommodate resin particles of different sizes. The filter screens 10 are connected to the bracket by snap-fit ​​connections, and the main body 6 is fixed at the top and bottom by flange bolts. An internal sealing ring is provided to prevent liquid leakage. The filter screens 10 can be replaced and cleaned by disassembling and assembling the upper and lower cavities of the main body 6. The cleaning spray module 13 is located above the stirring claw 4 and is connected to the water inlet 14 on the outer wall of the main body 6 via a pipeline. The cleaning spray module 13 has a fan-shaped spray structure, with the nozzle direction at a certain angle to the horizontal plane, which can cover the entire interior of the cavity and avoid direct water impact on the resin particles. The nozzles of the cleaning spray module 13 are evenly distributed and the angle is precisely set to meet the water flow coverage requirements. When the stirring claw 4 rotates and stirs the resin particles, the user connects the external water source to the water inlet 14 and injects water into the internal pipeline. Then the water flows out from the fan-shaped nozzle. After that, the resin particles flow down to the top filter screen 10, where larger impurities are filtered out. They then continue to flow into the lower filter screens 10 with different pore sizes, filtering out different impurities from large to small. Example 3

[0045] Furthermore, the inlet of the liquid storage tank 11 is connected to the outlet of the cavity body 6 via a pipe, and the first outlet of the liquid storage tank 11 is connected to the vacuum pump 12 for extracting liquid from the cavity. A manual shut-off valve 16 is installed between the inlet of the liquid storage tank 11 and the outlet of the cavity body 6 to regulate the fluid flow rate. A one-way valve 15 is installed at the first outlet of the liquid storage tank 11 to prevent backflow of liquid. The combined use of the one-way valve 15 and the manual shut-off valve 16 enhances the flexibility and safety of operation. When it is necessary to pump liquid into the liquid storage tank 11, the user opens the manual shut-off valve 16 and starts the vacuum pump 12 to pump the resin from the cavity body 6 into the liquid storage tank 11, while the one-way valve 15 prevents backflow of liquid.

[0046] The working principle of this device is as follows: First, the resin particles to be washed are placed into the main body 6 of the chamber. The drive motor 2 is started to rotate the transmission shaft 3, thereby creating a dynamic stirring field within the main body 6 using the stirring claws 4. The spiral arrangement of the stirring claws 4 ensures that the resin particles are fully agitated within the chamber, improving washing efficiency. Subsequently, an external water source is connected through the water inlet 14. The water flows through the nozzles of the cleaning spray module 13, forming a fan-shaped jet that covers the entire interior of the chamber and rinses the resin particles. The multi-layer filter screens 10 of the layered filtration assembly 9 separate impurities step by step, preventing resin particles from clogging the chamber. After washing, the manual shut-off valve 16 is opened, and the vacuum pump 12 draws the liquid from the main body 6 into the storage tank 11.

[0047] In the above embodiments, the connection and positional relationships of each component have been optimized to ensure the overall performance of the device. For example, the connection between the rotary drive assembly 1 and the washing chamber 5 is achieved through the transmission shaft 3 passing through the top cover 7. The fixed connection between the stirring claw 4 and the transmission shaft 3, as well as the support fixing of the layered filter assembly 9 and the chamber body 6, all adopt reliable mechanical connection methods. The nozzle arrangement and spray angle of the cleaning spray module 13 have been precisely calculated, achieving full coverage of the interior of the chamber while avoiding damage to the resin particles. In addition, the threaded connection between the top cover 7 and the chamber body 6, combined with the flexible sealing gasket 19, significantly improves the sealing performance, ensuring that no leakage problems occur during long-term operation of the device.

[0048] This utility model demonstrates the cooperative relationship between the components and their working process through the above specific embodiments, reflecting the feasibility of the device in practical applications.

[0049] To enable those skilled in the art to fully understand and implement this utility model, the operating principle and implementation steps of this device are further explained below in conjunction with specific application scenarios.

[0050] In practical applications, this resin washing device is mainly used to process resin particles of various sizes and shapes to meet the high-efficiency washing requirements in industrial production. The following are the specific operating steps and the corresponding technical principles behind their effectiveness:

[0051] First, the resin particles to be washed are loaded into the cavity body 6 through the filling port 51, ensuring a tight connection between the top cover 7 and the filling port 51. A sealing groove 18 is provided at the top of the filling port 51, and a flexible sealing gasket 19 is embedded within the sealing groove 18, securing the two together via a threaded connection. This design not only facilitates disassembly and maintenance by operators but also effectively prevents liquid leakage during washing. Next, the drive motor 2 is started, driving the stirring claws 4 to rotate via the transmission shaft 3. The stirring claws 4 are arranged in a spiral shape, with uniform gaps between adjacent stirring claws 4, creating a dynamic stirring field when rotating. This stirring field causes the resin particles to continuously tumble within the cavity body 6, avoiding the uneven washing problem caused by the fixed nature of traditional tray structures. This process, through the action of physical stirring force, loosens and removes impurities from the surface of the resin particles, thereby improving washing efficiency.

[0052] Next, an external water source is connected through the water inlet 14. The water flows through the nozzles of the cleaning spray module 13, forming a fan-shaped jet. The nozzles of the cleaning spray module 13 are angled to the horizontal plane, and their distribution is precisely calculated to ensure that the water flow covers the entire cavity. The water flow acts on the surface of the resin particles with appropriate force and angle, effectively rinsing the particles while avoiding damage caused by excessive water impact. The key to this setup lies in the optimization of the nozzle angle and the reasonable configuration of the nozzle density, which maximizes the protection of the integrity of the resin particles while ensuring cleaning effectiveness.

[0053] During the washing process, the layered filtration assembly 9 plays a crucial role. The layered filtration assembly 9 comprises multiple layers of filter screens 10, with the pore size of each layer gradually decreasing from top to bottom, separating impurities of different particle sizes step by step. The filter screens 10 are connected to the support frame via snap-fit ​​connections, facilitating easy replacement or cleaning by operators as needed. The layered filtration design solves the problem of traditional tray structures being unable to flexibly adapt to resin particles of different sizes, while also preventing clogging caused by impurity accumulation. Through step-by-step filtration, impurities are effectively separated and retained in their respective filter layers, while resin particles pass smoothly through the filters to continue participating in subsequent washing processes.

[0054] After washing is complete, the manual shut-off valve 16 is opened, and the vacuum pump 12 is started, drawing the washing liquid from the main chamber 6 into the storage tank 11. A one-way valve 15 is installed at the first outlet of the storage tank 11 to prevent liquid backflow and discharge. Finally, the fluid flow rate can be adjusted by manually shutting off the valve 16 to flexibly control the liquid extraction speed, thus adapting to different operational needs. This design enhances the operational flexibility and safety of the device, while also ensuring that the washing liquid is discharged in a timely manner, avoiding secondary contamination of the resin particles by residual liquid.

[0055] Finally, after washing and draining, the operator can easily remove the top cover 7 using the handle 20 to take out the cleaned resin particles. The threaded connection between the top cover 7 and the main body 6, along with the flexible sealing gasket 19, ensures that the device will not leak during long-term operation, thereby improving the service life and reliability of the equipment.

[0056] In summary, through the implementation steps and principles of the aforementioned specific application scenarios, this utility model demonstrates the feasibility and advantages of the device in actual operation. The cooperative relationship and optimized settings between the various components jointly achieve efficient washing of resin particles of different sizes and shapes, while solving problems such as uneven washing and insufficient sealing performance existing in traditional devices.
