[0004] However, existing technologies have the following problems when used:

[0005] Firstly, existing technologies mostly involve batch cleaning of quartz sand, requiring a single input of material, cleaning, and removal, which cannot continuously feed and discharge, leading to frequent interruptions in the operation process and low efficiency. Furthermore, material or impurities are easily left inside the equipment after each cleaning, requiring additional time for cleaning and further extending the processing cycle, making it difficult to adapt to the needs of large-scale production.

[0006] Secondly, existing technologies often lack grading and screening and circulating cleaning structures. It is difficult to completely separate impurities of different particle sizes in quartz sand through a single filtration, and some stubborn stains cannot be removed by a single water wash. Utility Model Content

[0007] The purpose of this invention is to address the aforementioned technical problems by providing a continuous quartz sand washing device that enables continuous quartz sand washing, avoids process interruptions to improve efficiency, and simultaneously combines grading and screening with circulating washing, effectively removing impurities and improving the purity of quartz sand.

[0008] In view of this, the present invention provides a continuous quartz sand washing device, including a box body. A first support is installed obliquely on the upper part of the inner cavity of the box body. A first filter screen is installed in the inner cavity of the first support. A second discharge chute is opened at the end of the first support. A second support is installed obliquely on the lower part of the inner cavity of the box body. A second filter screen is installed in the inner cavity of the second support. A first discharge chute is opened at the end of the box body. A hopper is installed obliquely on the end of the box body. A discharge pipe is installed at the end of the hopper. A guide pipe is installed at the lower end of the discharge pipe.

[0010] Furthermore, a groove is provided at the upper end of the box body, the first bracket is installed above the groove, and the second bracket is installed below the groove.

[0011] Furthermore, the lower end of the inner wall of the first discharge trough at the end of the box is aligned with the upper end of the second support.

[0012] Furthermore, the hopper is truncated triangular in shape, and a groove is provided at the upper end of the hopper, and the groove is also truncated triangular in shape.

[0013] Furthermore, a first mounting hole is provided at the end of the hopper, and the end of the feed pipe away from the guide pipe extends into the first mounting hole for fixation.

[0014] Furthermore, the inner cavity of the guide tube is provided with a guide hole, the upper end of the guide tube is provided with a second mounting hole, and the second mounting hole is connected to the guide hole, and the lower end of the discharge tube extends into the guide hole and is fixed.

[0016] The beneficial effects of this utility model are:

[0017] When cleaning quartz sand, this invention continuously pours it into the tank at the top of the chamber. Simultaneously, an external water supply mechanism delivers water to the nozzle at the top of the chamber via a first hose and a water guide pipe. The water sprayed from the nozzle fully contacts the quartz sand in the tank, washing away surface impurities. The quartz sand first falls onto the first filter screen supported by the first inclined bracket above the inner cavity of the chamber. The first filter screen filters out fine impurities, and the quartz sand slides along the inclined filter screen, flowing through the second discharge chute at the end of the first bracket to the second filter screen on the second inclined bracket below. The second filter screen further filters out impurities, and the quartz sand continues to slide, entering the hopper through the first discharge chute at the end of the chamber. The quartz sand in the hopper enters the guide hole of the guide pipe through the discharge pipe. An external air supply mechanism delivers air to the guide hole through the second hose and connecting pipe, pushing the quartz sand back into the chamber to undergo the cleaning and screening process again, forming a continuous cycle that ensures uninterrupted operation and improves cleanliness.

[0033] Please see Figures 1 to 8 The embodiments provided by this utility model are as follows:

[0034] Example: A continuous quartz sand washing device includes a housing 2. A first support 12 is installed at an angle above the inner cavity of the housing 2. A first filter screen 20 is installed inside the inner cavity of the first support 12. A second discharge chute 15 is opened at the end of the first support 12. A second support 14 is installed at an angle below the inner cavity of the housing 2. A second filter screen 21 is installed inside the inner cavity of the second support 14. A first discharge chute 13 is opened at the end of the housing 2. A hopper 8 is installed at an angle at the end of the housing 2. A discharge pipe 9 is installed at the end of the hopper 8. A guide pipe 7 is installed at the lower end of the discharge pipe 9. A connecting pipe 10 is installed at the front end of the guide pipe 7. A second flexible hose 11 is connected to the front end of the connecting pipe 10, and the front end of the second flexible hose 11 is connected to an external air supply mechanism.

[0035] In the example of this application, when the cleaning operation is started, quartz sand is continuously poured into the device, and at the same time, the external water supply mechanism delivers cleaning water to the nozzle 6 through the first hose 4 and the water guide pipe 5. The nozzle 6 sprays water evenly onto the quartz sand entering the tank 3 to achieve preliminary cleaning. At this time, the first bracket 12, which is installed at an angle above the inner cavity of the tank 2, provides stable support for the first filter screen 20. The inclined structure allows the quartz sand to flow naturally under its own gravity. During the flow, the first filter screen 20 can screen the quartz sand and filter out some impurities. At the same time, the cleaning water flows down along the gaps in the filter screen to further remove dirt from the surface of the quartz sand.

[0036] The sieved quartz sand flows along the first filter screen 20 to the second discharge chute 15 at the end of the first support 12, and then flows precisely through the discharge chute to the second support 14 below the inner cavity of the housing 2. The second support 14 is also inclined, and its inner cavity has a second filter screen 21 that can perform secondary sieving and washing of the quartz sand to further remove fine impurities and ensure washing accuracy. The quartz sand that has completed secondary treatment continues to flow along the second filter screen 21, and finally enters the hopper 8 through the first discharge chute 13 at the end of the housing 2, achieving preliminary collection after washing.

[0037] Quartz sand in hopper 8 enters the guide hole 17 of guide pipe 7 through the feed pipe 9 connected to its end. At the same time, the external air supply mechanism delivers gas into the guide hole 17 through the second hose 11 and connecting pipe 10. The thrust generated by the gas can push the quartz sand in the guide hole 17 back into the box 2 to participate in the cleaning process again. The entire process does not require interruption of feeding, which not only ensures the continuity of quartz sand cleaning, but also improves the cleaning cleanliness through multiple cycles. It effectively solves the problems of traditional cleaning devices that require batch processing, have low efficiency, and are not thorough in cleaning.

[0038] Furthermore, four pillars 1 are fixed in a rectangular array at the lower end of the box 2, and support plates are installed at the lower ends of the four pillars 1 respectively.

[0039] As a preferred example of this utility model, the four pillars 1 fixed in a rectangular array at the lower end of the box 2 can evenly distribute the weight of the box 2 itself, the weight of the quartz sand to be cleaned inside, and the weight of the water injected during the cleaning process to the four support points, thus avoiding deformation or tilting of the box 2 due to excessive local stress, which would affect the flow path of the quartz sand and the cleaning effect.

[0040] Meanwhile, the support plates installed at the lower ends of the four pillars 1 further increase the contact area between the pillars 1 and the ground, effectively reducing the pressure of the device on the ground. Even on uneven or weak ground, it can reduce the possibility of ground subsidence.

[0041] Furthermore, a groove 3 is provided at the upper end of the box body 2, the first bracket 12 is installed above the groove 3, and the second bracket 14 is installed below the groove 3.

[0042] As a preferred example of this utility model, the first support 12 is installed above the tank 3, so that the first filter screen 20 is in the first step of the quartz sand feeding process. The quartz sand can directly contact the cleaning water sprayed by the nozzle 6 as soon as it enters the device, and complete the initial screening and cleaning on the first filter screen 20, ensuring that impurities are filtered out as early as possible and reducing the burden of subsequent processing. The second support 14 is installed below the tank 3, so that the second filter screen 21 is located directly below the first filter screen 20, which can receive the quartz sand flowing down from the first filter screen 20 through the second discharge chute 15, realizing continuous processing from top to bottom. The cleaning water can penetrate from top to bottom in the tank 3, contacting the quartz sand on the first filter screen 20 and the second filter screen 21 in turn, improving the cleaning efficiency and avoiding the problem of uneven distribution of cleaning water.

[0043] Furthermore, the lower end of the inner wall of the first discharge trough 13 at the end of the box body 2 is aligned with the upper end of the second bracket 14.

[0044] As a preferred example of this utility model, the first discharge trough 13 opened at the end of the box 2 is a channel for quartz sand to flow from the second support 14 to the hopper 8. The lower end of its inner wall is aligned with the upper end of the second support 14, eliminating the height difference and gap between the two.

[0045] This design allows the quartz sand on the surface of the second filter screen 21 on the second support 14 to smoothly slide into the first discharge trough 13 under its own weight and the combined effect of the inclined structure of the second support 14. This prevents the quartz sand from accumulating at the end of the second support 14 due to height differences, and also prevents it from falling to the bottom of the tank 3 due to excessive gaps. Simultaneously, it avoids the accumulation of quartz sand clogging the filter holes of the second filter screen 21, ensuring that the second filter screen 21 maintains good screening and water permeability, guaranteeing the stable operation of the entire cleaning device and preventing interruptions to the continuous cleaning process due to material retention.

[0046] Furthermore, the hopper 8 is in the shape of a truncated triangle, and a groove 16 is provided at the upper end of the hopper 8, and the groove 16 is in the shape of a truncated triangle.

[0047] As a preferred example of this utility model, the hopper 8 adopts a triangular frustum structure, with the upper opening area being larger than the lower opening area. The shape, which is wider at the top and narrower at the bottom, can maximize the coverage of the outlet range of the first discharge trough 13, ensuring that all the quartz sand flowing out of the first discharge trough 13 can fall into the hopper 8, avoiding material loss caused by quartz sand leakage, and reducing the workload of cleaning up leaked materials later.

[0048] Furthermore, the triangular truncated groove 16 at the upper end of the hopper 8 matches the shape of the main body of the hopper 8, further guiding and converging the quartz sand. When the quartz sand falls into the hopper 8, it will be guided by the inclined inner wall of the groove 16 and flow naturally towards the bottom of the groove 16, and then enter the discharge pipe 9 connected to the bottom of the groove 16. This prevents the quartz sand from being dispersed and accumulated in the hopper 8, ensuring that the material can continuously and stably enter the subsequent return channel, providing a smooth material conveying guarantee for the circulating cleaning.

[0049] Furthermore, a first mounting hole 18 is provided at the end of the hopper 8, and the end of the feed pipe 9 away from the guide pipe 7 extends into the first mounting hole 18 for fixation.

[0050] As a preferred example of this utility model, the first mounting hole 18 at the end of the hopper 8 provides a clear positioning reference for the installation of the discharge pipe 9, so that the end of the discharge pipe 9 away from the guide pipe 7 can extend into the first mounting hole 18, avoiding the problem of quartz sand leakage caused by misalignment between the discharge pipe 9 and the hopper 8 due to installation deviation.

[0051] Meanwhile, the connection method of the feed pipe 9 extending into the first mounting hole 18 and being fixed can enhance the sealing and firmness of the connection between the two. After being fixed, the feed pipe 9 and the inner wall of the first mounting hole 18 are tightly fitted, eliminating the gap between the two and preventing the quartz sand from leaking or getting stuck in the gap during the process of entering the feed pipe 9 from the hopper 8. In addition, the firm connection can also prevent the feed pipe 9 from loosening or shifting due to vibration during the cleaning process, ensuring that the material conveying path is always stable, and providing a reliable connection guarantee for the smooth entry of quartz sand into the guide pipe 7 and the realization of backflow cleaning.

[0052] Furthermore, the inner cavity of the guide tube 7 is provided with a guide hole 17, and the upper end of the guide tube 7 is provided with a second mounting hole 19, and the second mounting hole 19 is connected to the guide hole 17. The lower end of the feed tube 9 extends into the guide hole 17 and is fixed.

[0053] As a preferred example of this utility model, the guide hole 17 opened in the inner cavity of the guide pipe 7 is a channel for the return of quartz sand. Its inner wall is smooth, which can reduce the resistance during the flow of quartz sand, prevent quartz sand from accumulating and blocking in the channel, and ensure that the quartz sand can flow smoothly from the feed pipe 9 to the box 2 and participate in the cleaning again.

[0054] The second mounting hole 19 at the upper end of the feed pipe 7 is connected to the feed hole 17. This connection allows the lower end of the feed pipe 9 to directly extend into and be fixed in the feed hole 17. This not only simplifies the installation structure but also connects the feed pipe 9 to the feed hole 17. After the quartz sand flows out of the feed pipe 9, it can directly enter the feed hole 17 without passing through an additional transition structure, thus avoiding material accumulation at the transition point. At the same time, it also ensures that the gas introduced by the external air supply mechanism through the connecting pipe 10 acts evenly on the quartz sand in the feed hole 17, forming a stable thrust that effectively pushes the quartz sand back to the housing 2 along the feed hole 17, ensuring the smooth operation of the circulating cleaning process.

[0055] Furthermore, a nozzle 6 is placed on the upper end of the housing 2, and a water guide pipe 5 is installed on the upper end of the nozzle 6. The end of the water guide pipe 5 is connected to a first flexible hose 4, and the end of the first flexible hose 4 is connected to an external water supply mechanism.

[0056] As a preferred example of this utility model, the nozzle 6 placed at the top of the housing 2 adopts a reasonable spraying structure, which can evenly spray the cleaning water onto the quartz sand below, ensuring that the quartz sand can fully contact the cleaning water, avoiding the problem of local quartz sand not being cleaned properly and surface dirt residue, and improving the overall cleaning cleanliness.

[0057] The water guide pipe 5 installed at the upper end of the nozzle 6 provides a stable delivery path for the cleaning water, enabling the water from the external water supply mechanism to be delivered to the nozzle 6, preventing leakage or pressure loss during water flow. The first flexible hose 4 connected to the end of the water guide pipe 5 has good flexibility, allowing for flexible adjustment of the connection angle and length, regardless of the installation location of the external water supply mechanism. This facilitates the layout and installation of the device in different locations, improving its operational flexibility. Furthermore, the connection between the first flexible hose 4 and the external water supply mechanism ensures a continuous and stable water supply, guaranteeing uninterrupted water flow during the cleaning process. This provides sufficient water resources for the continuous cleaning of quartz sand, preventing the cleaning process from stalling due to water shortages.

[0058] In this embodiment, when cleaning of quartz sand is required, the operator can continuously pour the quartz sand to be cleaned into the tank trough 3 at the top of the tank 2. The quartz sand falls naturally under its own gravity and enters the cleaning space formed by the tank trough 3. At the same time, the external water supply mechanism steadily delivers clean water to the water guide pipe 5 through the first hose 4. The water guide pipe 5 then accurately guides the water flow into the nozzle 6 installed at the top of the tank 2. The nozzle 6 sprays clean water evenly and with a wide coverage, forming a fine water curtain that fully contacts the quartz sand that has just entered the tank trough 3. The water flow can not only wash away loose impurities such as dirt and dust attached to the surface of the quartz sand, but also use the impact force to cause slight collisions and friction between the quartz sand particles, further removing stubborn stains.

[0059] The quartz sand entering the tank 3 first falls onto the first filter screen 20 supported by the first bracket 12, which is installed at an incline above the inner cavity of the tank 2. The mesh size of the first filter screen 20 is sufficient to perform preliminary screening of the quartz sand. Small impurities such as dust and fine sand with a particle size smaller than the mesh size will pass through the gaps of the first filter screen 20 with the water flow and be discharged downwards into the tank 3, while the quartz sand that meets the preliminary particle size requirements will be intercepted on the surface of the first filter screen 20. Since the first bracket 12 is in an inclined state, the first filter screen 20 also forms a certain slope, allowing the quartz sand remaining on the surface of the first filter screen 20 to slide naturally along the inclined direction without additional power. This avoids the accumulation of quartz sand on the first filter screen 20 and the resulting blockage, and also allows the quartz sand to come into contact with the continuously sprayed clean water again during the sliding process, enhancing the cleaning effect.

[0060] As the quartz sand flows continuously along the first filter screen 20, it eventually converges at the second discharge chute 15 at the end of the first support 12. The opening of the second discharge chute 15 corresponds to the second support 14 below, allowing the quartz sand to flow smoothly and leak-free from the second discharge chute 15 and fall directly onto the second filter screen 21 supported by the second support 14 installed below the inner cavity of the housing 2. The mesh size of the second filter screen 21 is slightly smaller than that of the first filter screen 20, allowing for secondary fine screening of the quartz sand to further filter out smaller impurities that were not separated in the first screening. At the same time, the cleaning water in the tank 3 continues to penetrate downwards, contacting the quartz sand on the second filter screen 21 to complete deep cleaning. Similarly, the second support 14 also adopts an inclined design, which pushes the quartz sand to slide continuously along the second filter screen 21 until it reaches the first discharge trough 13 at the end of the box 2. The lower end of the inner wall of the first discharge trough 13 is flush with the upper end of the second support 14, ensuring that the quartz sand can slide from the second filter screen 21 into the first discharge trough 13 without any obstruction, and finally flow smoothly into the hopper 8 connected to the first discharge trough 13.

[0061] The quartz sand entering hopper 8 has not completed the entire washing process. The triangular frustum structure of hopper 8 and the triangular frustum groove 16 at the top guide the quartz sand to converge at the bottom, causing it to fall continuously through the feed pipe 9 fixed in the first mounting hole 18 at the end of hopper 8, and finally enter the feed hole 17 in the inner cavity of the feed pipe 7. At this time, the external air supply mechanism continuously supplies gas into the feed hole 17 through the second hose 11 and the connecting pipe 10. The gas forms a stable thrust in the feed hole 17, pushing the quartz sand accumulated in the feed hole 17 to flow in the opposite direction and return to the tank trough 3 of the box body 2. The returned quartz sand undergoes the same cleaning process as when it first entered the machine, receiving water spray from nozzle 6, being graded and screened by the first filter screen 20 and the second filter screen 21, and finally entering the hopper 8 again for the next return. The entire process does not require machine shutdown and the quartz sand is continuously circulated, which not only ensures the continuity of the cleaning operation, but also significantly improves the cleanliness of the quartz sand through multiple cycles, effectively solving the problems of incomplete cleaning in a single cleaning and low efficiency of batch operation in traditional cleaning methods.
