Description

Technical Field

[0001] This utility model relates to the field of aquaculture, and in particular to a bottom sand washing device. Background Technology

[0002] In the aquaculture industry, it is necessary to clean the bottom sand regularly to avoid the accumulation of organic waste, the growth of pathogens, and the deterioration of water quality.

[0003] Existing methods for washing bottom sand typically employ a single water flow or mechanical agitation, which are limited in removing surface impurities from sand particles and are inefficient. Utility Model Content

[0004] Therefore, there is a need to provide a bottom sand washing device to solve the technical problem that existing bottom sand washing methods usually use a single water flow rinsing or mechanical stirring method, which has limited and low efficiency in removing impurities from the surface of sand particles.

[0005] To achieve the above objectives, this utility model provides a bottom sand washing device, comprising:

[0006] The filtering mechanism includes a first rotating cylinder, a first filter screen, and a first rotating motor. The first filter screen is installed at the bottom of the first rotating cylinder, and the output end of the first rotating motor is connected to the first filter screen.

[0007] The buffer cleaning mechanism includes a second rotating cylinder, a second filter screen, a spiral frame, and a second rotating assembly. The second rotating cylinder is installed below the first rotating cylinder and is rotatably connected to the first rotating cylinder. The second filter screen is installed at the bottom inside the second rotating cylinder. The spiral frame is installed inside the second rotating cylinder. The second rotating assembly drives the second rotating cylinder to rotate, and the sand particles are slowly washed through the spiral frame.

[0008] Unlike existing technologies, the above-mentioned technical solution uses a filtration mechanism to initially separate large particles of impurities from the sand. Afterward, the sand passes through a spiral frame, which, under the action of the second rotating component, slowly tumbles the sand, prolonging the contact time between the sand and the water flow, gently peeling off impurities, and further removing impurities from the surface of the sand, thus improving cleaning efficiency.

[0009] In one embodiment of this utility model, the second rotating assembly includes a ring rack, a gear, and a second rotating motor. The ring rack is sleeved outside the second rotating cylinder, the gear meshes with the ring rack, and the output end of the second rotating motor is connected to the gear. The second rotating motor drives the gear to rotate, thereby causing the second rotating cylinder to rotate.

[0010] In this way, the gear and ring rack transmission ensures stable torque of the second rotating drum, prevents jamming, and improves transmission efficiency. At the same time, since the diameter of the gear is smaller than that of the ring rack, it can reduce speed, thus allowing the sand particles to be slowly washed on the auger.

[0011] As one embodiment of this utility model, the bottom sand washing device also includes a vibration washing mechanism, which includes a third rotating cylinder, a third filter screen, a drum, and a first vibrator. The third rotating cylinder is installed below the second rotating cylinder and is rotatably connected to the second rotating cylinder. The bottom of the third rotating cylinder is equipped with a third filter screen, and the first vibrator is installed on the third filter screen. The drum is installed inside the third rotating cylinder and the first vibrator is installed inside the drum.

[0012] Thus, the first vibrator can accelerate the sieving efficiency of sand particles on the one hand, and prevent sand particles from caking on the other.

[0013] As one embodiment of this utility model, the vibration cleaning mechanism also includes two or more brush bristles, which are installed around the outside of the drum in a circumferential direction.

[0014] In this way, the bristles vibrate and rub against the surface of the sand grains under the action of the first vibrator to remove fine impurities.

[0015] In one embodiment of this utility model, the top of the roller is conical.

[0016] Thus, the cone-shaped top of the roller guides the sand particles to disperse evenly, preventing them from clogging and preventing them from flowing down.

[0017] In one embodiment of this utility model, the mesh count of the third filter screen is greater than that of the second filter screen, and the mesh count of the second filter screen is greater than that of the first filter screen.

[0018] In this way, the progressively larger mesh size of the filter screen is subjected to pressure in stages, with each layer intercepting impurities of different particle sizes, avoiding overloading of a single layer and extending the filter screen's lifespan.

[0019] In one embodiment of this utility model, the top of the spiral frame is conical.

[0020] In this way, the cone-shaped top of the spiral frame can guide the sand grains to be evenly dispersed, preventing the sand grains from clogging and not flowing down.

[0021] As one embodiment of this utility model, the buffer cleaning mechanism also includes a second vibrator, which is installed inside the screw frame.

[0022] Thus, the second vibrator helps to loosen the bonded sand clumps and remove medium-sized impurities.

[0023] The above description of the utility model is merely an overview of the technical solution of this application. In order to enable those skilled in the art to better understand the technical solution of this application and to implement it based on the description and drawings, and to make the above-mentioned objectives and other objectives, features and advantages of this application easier to understand, the following description is provided in conjunction with the specific embodiments and drawings of this application.

[0044] Existing methods for washing bottom sand typically employ a single water flow or mechanical agitation, which are limited in removing surface impurities from sand particles and are inefficient.

[0045] In view of this, this application provides a bottom sand washing device 100, including a filtration mechanism 1 and a buffer washing mechanism 2. The filtration mechanism 1 includes a first rotating cylinder 11, a first filter screen 12, and a first rotating motor 13. The first filter screen 12 is installed at the bottom of the first rotating cylinder 11, and the output end of the first rotating motor 13 is connected to the first filter screen 12. The buffer washing mechanism 2 includes a second rotating cylinder 21, a second filter screen 22, a spiral frame 23, and a second rotating assembly 24. The second rotating cylinder 21 is installed below the first rotating cylinder 11 and is rotatably connected to the first rotating cylinder 11. The second filter screen 22 is installed at the bottom of the second rotating cylinder 21, and the spiral frame 23 is installed inside the second rotating cylinder 21. The second rotating assembly 24 drives the second rotating cylinder 21 to rotate, and the sand particles are slowly washed by the spiral frame 23.

[0046] According to some embodiments of this application, please refer to Figures 1 to 7 This embodiment relates to a bottom sand washing device 100, including a filtration mechanism 1 and a buffer washing mechanism 2. The filtration mechanism 1 includes a first rotating cylinder 11, a first filter screen 12, and a first rotating motor 13. The first filter screen 12 is installed at the bottom inside the first rotating cylinder 11, and the output end of the first rotating motor 13 is connected to the first filter screen 12. The buffer washing mechanism 2 includes a second rotating cylinder 21, a second filter screen 22, a spiral frame 23, and a second rotating assembly 24. The second rotating cylinder 21 is installed below the first rotating cylinder 11 and is rotatably connected to the first rotating cylinder 11. The second filter screen 22 is installed at the bottom inside the second rotating cylinder 21, and the spiral frame 23 is installed inside the second rotating cylinder 21. The second rotating assembly 24 drives the second rotating cylinder 21 to rotate, and the sand particles are slowly washed by the spiral frame 23.

[0047] The first rotating motor 13 can be fixed on the external frame. The output end of the first rotating motor 13 is connected to the first filter screen 12, thereby driving the entire first rotating cylinder 11 to rotate relative to the second rotating cylinder 21, so that the first filter screen 12 separates large particles of impurities such as leaves and stones, preventing clogging of the downstream mechanism. In some embodiments, the first rotating motor 13 can be an oscillating motor, which plays an oscillating role.

[0048] The second rotating cylinder 21 has an opening at the top, allowing sand particles filtered by the first filter screen 12 to enter. A spiral frame 23 is installed inside the second rotating cylinder 21, with its bottom mounted on the second filter screen 22. The spiral frame 23 is located in the middle of the second rotating cylinder 21. The spiral frame 23 is a conventional structure, spiraling from the top to the bottom of the second rotating cylinder 21. The second rotating cylinder 21 rotates under the action of a second rotating assembly 24, which can be a conventional rotating structure, such as a motor driven by a belt.

[0049] Unlike existing technologies, the above-mentioned technical solution sets up a filter mechanism 1 to initially separate large particles of impurities in the sand. Then, the sand passes through a spiral frame 23, which rotates the sand at low speed under the action of the second rotating component 24, prolonging the contact time between the sand and the water flow, gently peeling off impurities, and further removing impurities from the surface of the sand, thus improving cleaning efficiency.

[0050] like Figure 3 and Figure 4 As shown, the second rotating assembly 24 includes an annular rack 241, a gear 242, and a second rotating motor 243. The annular rack 241 is sleeved on the outside of the second rotating cylinder 21. The gear 242 meshes with the annular rack 241. The output end of the second rotating motor 243 is connected to the gear 242. The second rotating motor 243 drives the gear 242 to rotate, so that the second rotating cylinder 21 rotates.

[0051] The second rotating motor 243 can be fixed on the outer frame, so that the ring rack 241 rotates relative to the gear 242, thereby causing the second rotating cylinder 21 to rotate.

[0052] Thus, the transmission between gear 242 and ring rack 241 ensures stable torque of the second rotating drum 21, prevents jamming, and improves transmission efficiency. At the same time, since the diameter of gear 242 is smaller than that of ring rack 241, it can reduce speed, thereby allowing sand particles to be slowly washed on the spiral frame 23.

[0053] like Figure 1 , Figure 6 and Figure 7 As shown, the bottom sand washing device 100 also includes a vibration washing mechanism 3. The vibration washing mechanism 3 includes a third rotating cylinder 31, a third filter screen 32, a drum 33, and a first vibrator 34. The third rotating cylinder 31 is installed below the second rotating cylinder 21 and is rotatably connected to the second rotating cylinder 21. The third filter screen 32 is installed at the bottom inside the third rotating cylinder 31. The first vibrator 34 is installed on the third filter screen 32. The drum 33 is installed inside the third rotating cylinder 31. The first vibrator 34 is installed inside the drum 33.

[0054] The top opening of the second rotating drum 21 allows the sand particles filtered by the second filter screen to enter the third rotating drum 31. A drum 33 is installed inside the third rotating drum 31, with its bottom mounted on the second filter screen 22. The drum 33 is located in the middle of the third rotating drum 31. A first vibrator 34 is installed inside the drum 33 for vibration. The first vibrator 34 accelerates the sieving efficiency of the sand particles and prevents sand particles from caking.

[0055] like Figure 6 As shown, the vibration cleaning mechanism 3 also includes two or more brush bristles 35, which are mounted around the outside of the roller 33 in a circumferential manner.

[0056] Optionally, the 35 bristles are arranged radially to increase the cleaning contact area and improve the removal rate of adhering impurities.

[0057] Thus, the bristles 35 vibrate and rub against the surface of the sand particles under the action of the first vibrator 34 to remove fine impurities.

[0058] like Figure 6 As shown, the top of roller 33 is conical.

[0059] Thus, the cone-shaped top of roller 33 guides the sand particles to disperse evenly, preventing them from clogging and flowing down.

[0060] like Figure 2 , Figure 4 and Figure 6 As shown, the mesh count of the third filter 32 is greater than that of the second filter 22, and the mesh count of the second filter 22 is greater than that of the first filter 12.

[0061] In this way, the progressively larger mesh size of the filter screen is subjected to pressure in stages, with each layer intercepting impurities of different particle sizes, avoiding overloading of a single layer and extending the filter screen's lifespan.

[0062] like Figure 3 and Figure 5 As shown, the top of the screw carrier 23 is conical.

[0063] Thus, the cone-shaped top of the spiral frame 23 can guide the sand grains to be evenly dispersed, preventing the sand grains from clogging and not flowing down.

[0064] According to some embodiments of this application, optionally, the buffer cleaning mechanism 2 further includes a second vibrator, which is installed inside the screw frame 23.

[0065] Thus, the second vibrator helps to loosen the bonded sand clumps and remove medium-sized impurities.

[0066] The working principle of the bottom sand washing device 100 is as follows: First, sand particles enter from the top inlet with a strong water flow. Under the action of the first rotating motor 13, large particles of impurities are filtered through the first filter screen 12. Second, the sand particles after high-speed washing enter the spiral frame 23. Under the deceleration action of the second rotating motor 243, gear 242, and annular rack 241, the sand particles are slowly washed on the spiral frame 23. Third, the sand particles enter the third rotating cylinder 31, where the bristles 35 deeply clean the sand particles under the action of the first vibrator 34, removing fine impurities. Finally, the cleaned sand particles are discharged from the bottom of the third rotating cylinder 31, completing the entire washing process. Unlike existing technologies, the three-stage washing process of this application can effectively remove fine impurities from the surface of sand particles, improving the washing effect. At the same time, the spiral frame 23 ensures the meticulousness and uniformity of the washing process, and the dense nano-level bristle array 35 improves the washing efficiency.

[0067] In this embodiment, the power mechanism or power unit includes, but is not limited to, engines, motors, pneumatic tools, hydraulic pumps, etc. The power unit also includes direct power sources and indirect power sources. Direct power sources are those that can provide their own power, such as engines and motors, while indirect power sources include cylinders and hydraulic cylinders. The power mechanism or power unit can drive the linear reciprocating motion of the actuator through gear and rack engagement, slider and groove engagement, lead screw and nut engagement, etc.

[0068] In this embodiment, the transmission mechanism or transmission unit includes a speed reducer, gearbox, worm gear mechanism, linkage mechanism, compound mechanism, etc. The transmission mechanism or transmission unit is used to transmit power from the power mechanism or power unit to the actuator or actuator.
