Description

Technical Field

[0001] This utility model relates to the field of hierarchical screening and cleaning technology, and more specifically, to a non-destructive hierarchical screening and cleaning device. Background Technology

[0002] A tiered screening and cleaning device is a high-efficiency equipment that achieves material screening and cleaning through a layered structure. Its core feature is the use of different levels of filter screens combined with vibration or water spraying to improve processing efficiency. However, existing screening and cleaning devices still have the following drawbacks:

[0003] (1) Traditional screening and cleaning devices often use vibrating screens and swing screens. The material will be subjected to violent vibration, shaking and collision in the device. Some devices use spiral propulsion and extrusion for screening and cleaning. The material will be subjected to greater pressure between the spiral blades or extrusion components, which will cause the outer shell of the material to break, resulting in an incomplete product appearance and affecting the quality of the material.

[0004] (2) Some cleaning devices use a large amount of water for rinsing in order to achieve a certain cleaning effect, which wastes water resources. Moreover, if the wastewater after cleaning is discharged directly, it will also pollute the environment. Therefore, a non-destructive hierarchical screening and cleaning device is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the problem that existing non-destructive hierarchical screening and cleaning devices often use vibrating screens and swing screens, where materials are subjected to violent vibration, shaking, and collisions. Some devices use a spiral propulsion and extrusion method for screening and cleaning, where materials are subjected to great pressure between the spiral blades or extrusion components, which can cause the material shell to crack, resulting in incomplete product appearance and affecting the quality of the materials.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] The present invention is as follows: a non-destructive hierarchical screening and cleaning device, including a base plate, a screening mechanism for hierarchical screening is provided on one side of the top of the base plate, and a recycling component for easy cyclic cleaning is provided on one side of the screening mechanism.

[0008] The screening mechanism includes a frame fixedly connected to the top of a base plate. Support blocks are fixedly connected to both ends of the top of the frame. Support rollers are rotatably connected to the side walls of the support blocks. A roller is rotatably connected to the top of the support rollers. The roller is inclined. Several through holes are opened on the outer wall of the roller. A ring is fixedly connected to the inner wall of the roller. Several round tubes are fixedly connected to the side walls opposite to the ring. A ring gear is fixedly connected to the outer wall of the roller. A motor is installed at the top of the frame. A drive gear is fixedly connected to the output end of the motor. The drive gear meshes with the ring gear. A storage trough is provided at the bottom of the roller. A partition is fixedly connected to the inner wall of the middle part of the storage trough. The screening mechanism also includes a cleaning component installed on one side of the roller for cleaning materials.

[0009] As a preferred technical solution of this utility model, the cleaning assembly includes a water tank disposed on one side of the top of the base plate, a drain pipe connected to the side wall of the bottom of the water tank, a solenoid valve disposed on the outer wall of the drain pipe, a strip plate disposed on the top of the water tank, a booster pump disposed on the top of the strip plate, an inlet pipe connected to the input end of the booster pump, an outlet pipe connected to the output end of the booster pump, and a spray head connected to the bottom of the outlet pipe.

[0010] As a preferred technical solution of this utility model, the recycling component includes a water supply pipe connected to the bottom side wall of the storage tank. One end of the water supply pipe is connected to the bottom of the water tank. A slot is provided on the inner wall of the water tank. A filter plate is slidably connected to the side wall of the slot. A one-way valve is provided on the side wall at the bottom of the water inlet pipe.

[0011] As a preferred technical solution of this utility model, a slot plate is hinged to the opposite side wall of the storage slot, and an electric push rod is provided on the opposite side wall of the partition, with a push plate fixedly connected to the output end of the electric push rod.

[0012] As a preferred technical solution of this utility model, a rectangular plate is fixedly connected to the opposite side wall of the frame, a support rod is fixedly connected to the top of the rectangular plate, a support block is fixedly connected to the top of the support rod, and the top of the support block is slidably connected to the side wall of the water outlet pipe.

[0014] As a preferred technical solution of this utility model, the roller and the round tube are made of stainless steel.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. Through the set screening mechanism, the motor drives the drive gear to rotate, and then the ring gear drives the drum to rotate together. Then, the material to be screened is put into the higher end of the drum. Under the action of its own gravity, the material moves slowly along the inner wall of the drum to the lower end. It falls into different areas separated by partitions in the storage tank through the circular pipes of different densities, completing the classification and collection of the material. Then, water needed to clean the material is injected into the water tank. The water inlet pipe draws water into the booster pump. The booster pump pressurizes the pumped clean water and delivers it to the spray head through the water outlet pipe. The spray head disperses the high-pressure water flow into fine water droplets and sprays them evenly on the surface of the material that has entered the water tank area after screening, cleaning the material. This realizes the integrated operation of screening and cleaning, reducing the transfer links of material between different equipment.

[0017] 2. Through the set recycling components, the wastewater after cleaning carries impurities from the surface of the materials into the storage tank. The wastewater will flow from the storage tank into the water tank through the water supply pipe. Solid impurities in the wastewater will be intercepted by the filter plate, while the relatively clean water will pass through the filter plate and remain in the water tank. The water filtered by the filter plate can be stored in the water tank for subsequent cleaning operations, realizing the recycling of water resources, reducing water consumption, and lowering production costs.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0025] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] like Figure 1 As shown, this embodiment proposes a non-destructive hierarchical screening and cleaning device, including a base plate 1, a screening mechanism 2 for hierarchical screening is provided on one side of the top of the base plate 1, and a recycling component 3 for easy cyclic cleaning is provided on one side of the screening mechanism 2.

[0029] like Figure 2 , Figure 3 and Figure 4As shown, the screening mechanism 2 includes a frame 201 fixedly connected to the top of the base plate 1. The frame 201 provides a stable mounting foundation for other components, preventing deformation or displacement due to vibration or material impact. Support blocks 202 are fixedly connected to both ends of the top of the frame 201. Support rollers 203 are rotatably connected to the side walls of the support blocks 202. A roller 204 is rotatably connected to the top of the support rollers 203. The roller 204 is inclined. The support rollers 203 support the roller 204 through rolling friction, reducing the frictional resistance when the roller 204 rotates, allowing the roller 204 to rotate smoothly. The inclination of the roller 204 utilizes gravity to allow the material to automatically move from the high end to the low end within the roller 204. Several openings are formed on the outer wall of the roller 204. A through hole 205 allows material to fall through during the rotation of the drum 204. Three rings 206 are fixedly connected to the inner wall of the drum 204, and several round tubes 207 are fixedly connected to the opposite side walls of the three rings 206. The round tubes 207 are arranged with a sparse upper section and a dense lower section. The rings 206 support and fix the round tubes 207, allowing them to be arranged in a certain pattern inside the drum 204, forming a hierarchical screening structure. A ring gear 208 is fixedly connected to the outer wall of the drum 204. A motor 209 is installed at the top of the frame 201, and a drive gear 210 is fixedly connected to the output end of the motor 209. The drive gear 210 meshes with the ring gear 208, and the motor 209 serves as the power source, driving the drive gear. When the drive gear 210 rotates, it drives the ring gear 208 to rotate, which in turn causes the drum 204 to rotate. A storage trough 211 is provided at the bottom of the drum 204 to collect materials screened from within the drum 204. A partition 212 is fixedly connected to the inner wall of the middle section of the storage trough 211, dividing it into different areas to prevent materials of different specifications from mixing. The screening mechanism 2 also includes a cleaning component 213 located on one side of the drum 204 for cleaning the materials. When in use, the motor 209 is started, and its output drives the drive gear 210 to rotate. Since the drive gear 210 meshes with the ring gear 208, the ring gear 208 drives the drum 204 to rotate together. The support roller 203 rotates on the support block 202, providing stable support for the drum 204, allowing the drum 204 to rotate smoothly around its own axis. The material to be screened is then fed into the drum 204 from the higher end. Under its own gravity, the material slowly moves along the inner wall of the drum 204 towards the lower end. Larger particles cannot pass through the gaps between the larger-spaced upper circular tubes 207 and continue to rotate with the drum 204 towards the lower end. Medium-sized particles can pass through the gaps between the upper circular tubes 207 but are intercepted by the smaller-spaced lower circular tubes 207, continuing to rotate with the drum 204 at the corresponding level. Smaller particles can pass through the gaps between the lower circular tubes 207 and fall further into the storage trough 211.After screening, materials of different specifications fall into different areas separated by partitions 212 in the storage trough 211 at the bottom of the drum 204, completing the classification and collection of materials. The friction between materials during screening is relatively gentle, avoiding damage to the materials and improving screening accuracy and efficiency, thus meeting the production needs with strict requirements on material specifications.

[0030] like Figure 4 As shown, the cleaning assembly 213 includes a water tank 2131 disposed on one side of the top of the base plate 1. The water tank 2131 is used to store water required for cleaning. A drain pipe 2132 is connected to the side wall at the bottom of the water tank 2131. A solenoid valve 2133 is disposed on the outer wall of the drain pipe 2132. The drain pipe 2132 can discharge wastewater to replace it with fresh water. By controlling the opening and closing of the solenoid valve 2133, the drainage time and flow rate of the water tank 2131 can be precisely controlled to realize automated drainage operation. A strip plate 2134 is installed at the top of 2131, and a booster pump 2135 is installed at the top of the strip plate 2134. The booster pump 2135 provides a power source for water supply. The input end of the booster pump 2135 is connected to a water inlet pipe 2136, which transports clean water from the water tank 2131 to the booster pump 2135, ensuring that the booster pump 2135 has sufficient water for pumping. The output end of the booster pump 2135 is connected to a water outlet pipe 2137, and the bottom of the water outlet pipe 2137 is connected to... Equipped with a spray head 2138, the water outlet pipe 2137 delivers the high-pressure water flow output from the booster pump 2135 to the spray head 2138, allowing the water flow to be accurately sprayed onto the material to be cleaned. The spray head 2138 can disperse the high-pressure water flow into fine water droplets, spraying them evenly onto the surface of the material. In use, first, the water required for cleaning the material is injected into the water tank 2131. Then, the booster pump 2135 is started, and the water inlet pipe 2136 draws water into the booster pump 2135. The booster pump 2135 then sprays the drawn water... After the water is pressurized, it is delivered to the spray head 2138 through the water outlet pipe 2137. The spray head 2138 disperses the high-pressure water flow into fine water droplets and sprays them evenly on the surface of the material that has been screened and entered the water tank 2131 area to clean the material. This realizes the integrated operation of screening and cleaning, reduces the transfer links of materials between different equipment, reduces the risk of contamination and damage of materials during the transfer process, ensures that all parts of the material can be thoroughly cleaned, and improves the cleaning coverage area and cleaning effect.

[0031] like Figure 5As shown, the recycling component 3 includes a water supply pipe 301 connected to the bottom side wall of the storage tank 211. One end of the water supply pipe 301 is connected to the bottom of the water tank 2131, transporting the used water from the storage tank 211 to the water tank 2131. A slot 302 is provided on the inner wall of the water tank 2131, and a filter plate 303 is slidably connected to the side wall of the slot 302. The slot 302 provides the installation position and positioning reference for the filter plate 303. The filter plate 303 filters the wastewater and intercepts solid impurities. A one-way valve 304 is provided on the side wall at the bottom of the inlet pipe 2136. The one-way valve 304 only allows water to flow in one direction to prevent backflow and ensure that the water flows in the prescribed direction. The wastewater after cleaning carries impurities from the surface of the materials into the storage tank 2131. 1. Wastewater flows from storage tank 211 into water tank 2131 through water pipe 301. When wastewater enters water tank 2131 from water pipe 301, solid impurities in the wastewater are intercepted by filter plate 303, while cleaner water passes through filter plate 303 and remains in water tank 2131. The water filtered by filter plate 303 can be stored in water tank 2131 for subsequent cleaning operations, realizing the recycling of water resources. When a certain amount of impurities accumulate on filter plate 303, filter plate 303 can be pulled out from slot 302 for cleaning. After cleaning, it is reinstalled to ensure the filtration effect, reduce water consumption, lower production costs, ensure the stability and uniformity of cleaning water flow, improve cleaning effect, and ensure the quality of cleaned materials.

[0032] like Figure 1 As shown, a trough plate 4 is hinged to the opposite side wall of the storage tank 211, and an electric push rod 5 is provided on the opposite side wall of the partition plate 212. The output end of the electric push rod 5 is fixedly connected to a push plate 6. When the material after screening and cleaning is piled up in the storage tank 211, the push plate 6 is pushed forward under the action of the electric push rod 5, pushing the material to the trough plate 4. By controlling the opening and closing of the trough plate 4, the material can be directionally discharged, which is convenient for subsequent processing and improves processing efficiency.

[0033] like Figure 1 As shown, a rectangular plate 7 is fixedly connected to the opposite side wall of the frame 201. A support rod 8 is fixedly connected to the top of the rectangular plate 7. A support block 9 is fixedly connected to the top of the support rod 8. The top of the support block 9 is slidably connected to the side wall of the water outlet pipe 2137. During the material cleaning process, the booster pump 2135 drives the water flow to flow at high speed in the water outlet pipe 2137, which will generate a certain vibration and impact force. The support rod 8 and the support block 9 can firmly support the water outlet pipe 2137 at the specified height and position, effectively preventing the water outlet pipe 2137 from shaking or shifting due to vibration, and ensuring the accuracy of the position of the water outlet pipe 2137.

[0034] like Figure 1As shown, a guide plate 10 is provided on the top of the storage tank 211. The guide plate 10 is inclined and can effectively limit the movement range of the material, guide the material into the storage tank 211, reduce the scattering and waste of the material during the transfer process, and improve the efficiency of material collection.

[0035] like Figure 1 As shown, the roller 204 and the round tube 207 are made of stainless steel. Stainless steel can effectively resist corrosion, ensuring that the roller 204 and the round tube 207 will not be corroded during long-term use, thus reducing maintenance and replacement costs.

[0036] Specifically, in use, the non-destructive tiered screening and cleaning device works as follows: First, connect the motor 209, booster pump 2135, and electric actuator 5 to an external power source. Then, start the motor 209, whose output drives the drive gear 210 to rotate. This, in turn, causes the ring gear 208 to rotate the drum 204. The support roller 203 rotates on the support block 202, providing stable support for the drum 204, allowing it to rotate smoothly around its own axis. Next, the material to be screened is fed into the drum 204 from the higher end. Under its own gravity, the material slowly moves along the inner wall of the drum 204 towards the lower end. Larger particles cannot pass through the gaps between the larger-spaced upper circular tubes 207 and continue to move towards the lower end as the drum 204 rotates. Medium-sized particles can pass through the gaps between the upper circular tubes 207. The gaps are blocked, but the smaller particles are intercepted by the smaller-spaced lower circular tubes 207 and continue to rotate with the drum 204 at the corresponding level. Smaller particles can pass through the gaps between the lower circular tubes 207 and fall further into the storage tank 211. After screening, materials of different specifications will fall into different areas separated by partitions 212 in the storage tank 211 at the bottom of the drum 204, completing the classification and collection of materials. At the same time, water needed for cleaning the materials is injected into the water tank 2131, and the booster pump 2135 is started. The water inlet pipe 2136 draws water into the booster pump 2135. The booster pump 2135 pressurizes the drawn clean water and delivers it to the spray head 2138 through the water outlet pipe 2137. The spray head 2138 disperses the high-pressure water flow into fine water droplets and sprays them evenly on the surface of the materials that have been screened and entered the area of ​​the water tank 2131, cleaning the materials (such as...). Figure 2 , Figure 3 and Figure 4 As shown), the wastewater after cleaning, carrying impurities from the material surface, flows into the storage tank 211. The wastewater then flows from the storage tank 211 into the water tank 2131 through the water pipe 301. When the wastewater enters the water tank 2131 from the water pipe 301, solid impurities in the wastewater are intercepted by the filter plate 303, while the relatively clean water passes through the filter plate 303 and remains in the water tank 2131. The water filtered by the filter plate 303 can be stored in the water tank 2131 for subsequent cleaning operations (such as...). Figure 5 (As shown).

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
