Description

Technical Field

[0001] The invention relates to the technical field of sand washing, and more particularly to an automatic sand washing cyclone desander and an automatic sand washing method. Background Art

[0002] With the improvement of building standards and the requirements for construction quality, artificial sand and natural sand contain impurities such as stone dust and soil, which will separate the cement in the concrete and cause the structural skeleton to loosen. Therefore, these sands and gravels need to pass through sand washing equipment before use. Currently, cyclone sand removers are generally used for sand and gravel cleaning.

[0003] The cyclone desander can separate sand and water by utilizing the principle of centrifugal separation, and at the same time, impurities on the surface of the sand and gravel will be discharged synchronously with the water, thereby achieving the purpose of sand and gravel cleaning. However, the existing cyclone desander has the following problems in the process of sand and gravel cleaning: when the existing cyclone desander is in use, it is necessary to open the water inlet and outlet valves and close the drain valve, so the settled sand and gravel are finally accumulated in the sand discharge pipe. When the sand and gravel accumulate in the sand discharge pipe to a certain extent, it is necessary to manually open the drain valve and the cyclone desander stops running. This method cannot continuously clean and collect the sand and gravel, thereby reducing the cleaning efficiency and speed of the sand and gravel.

[0016] An automatic sand washing method, the specific operation steps are as follows: S1, the sand and water mixture is conveyed under pressure and finally conveyed to the ceramic cyclone cylinder through the conveying pipe. Since the conveying pipe is installed at the eccentric position of the ceramic cyclone cylinder, when the water passes through the conveying pipe of the cyclone desander, it first forms a surrounding fluid obliquely downward along the tangential direction of the ceramic cyclone cylinder, and the water flow rotates and moves downward. Due to the different densities of sand and water, under the combined action of centrifugal force, centripetal force, buoyancy and fluid drag, the water with low density rises and is discharged through the overflow pipe, while the sand and gravel fall into the sand discharge pipe along the cone wall under the action of fluid inertia centrifugal force and its own gravity, and then fall into the collection tank;

[0017] S2. When the sensor detects that one of the sand and gravel collection tanks is full, the hydraulic cylinder pulls or pushes the two collection tanks to move on the supporting bottom plate, so that the other collection tank moves to the bottom of the sand discharge pipe, so that the sand and gravel in the sand discharge pipe can fall into the new collection tank, and the butterfly valve at the bottom of the other full collection tank automatically opens;

[0018] S3. When the collecting tank moves further away from the sand discharge pipe, the fixed extrusion block cannot squeeze the contact rod, so the docking ring moves downward under the pull of the second tension spring, and the extrusion assembly no longer contacts the trigger rod. Therefore, the rack moves to the initial position under the pull of the first tension spring, so that the sealing baffle rotates to the initial position and blocks the sand discharge pipe. At this time, sand and gravel accumulate on the sealing baffle;

[0019] S4. When a new collection tank moves toward the side close to the sand discharge pipe, the contact rod contacts the inclined surface of the fixed extrusion block, so that the inclined surface of the fixed extrusion block will form a thrust on the contact rod, causing the contact rod to move toward the side close to the collection tank. At the same time, the rotating push plate will cause the sleeve slide to move upward, and the second tension spring will be stretched, causing the docking ring to move upward synchronously. When the collection tank moves to the bottom of the sand discharge pipe, the contact rod moves to the top of the fixed extrusion block. At this time, the contact rod moves to the maximum distance, so that the docking ring fits the lower side of the sand discharge pipe.

[0020] S5. During the upward displacement of the docking ring, the extrusion assembly moves upward synchronously with the docking ring, so that the inclined surface of the extrusion top plate contacts the trigger rod, thereby pushing the trigger rod to move to one side inside the external shell, and the rack moves synchronously with the trigger rod. At the same time, the first tension spring is stretched, and the rack drives the gear to rotate synchronously, and the worm rotates synchronously with the gear, so the worm drives the worm wheel to rotate synchronously. At this time, the rotating shaft drives the sealing baffle to rotate ninety degrees, so that the sealing baffle no longer blocks the sand discharge pipe, so the sand and gravel in the sand discharge pipe falls into the collection tank through the sand discharge pipe.

[0021] The advantages of the present invention are:

[0022] Firstly, the present invention is provided with a hydraulic cylinder, a sealing assembly, a lifting mechanism and an extrusion assembly, so that the sand and gravel accumulated in the collection tank can be automatically cleaned without stopping the cyclone sand remover, and the sand and gravel dropped from the sand discharge pipe can be continuously collected. No sand and gravel loss will occur during the cleaning process, thereby further improving the cleaning efficiency and speed of the sand and gravel.

[0023] Secondly, the present invention can automatically control the docking ring to move upward or downward when the collecting tank moves to a specified position, without the need for manual control, thereby greatly improving the automation of the device.

[0024] Third, the present invention uses a worm gear to drive the sealing baffle. Since the worm gear has a self-locking effect, when the sealing baffle is horizontal and sand and gravel continue to fall onto the sealing baffle, the sealing baffle will not rotate due to the limitation of the self-locking effect, further ensuring the use effect of the sealing assembly.

[0025] Fourthly, the present invention can automatically open the sealing component after the docking ring rises through the extrusion component, has high linkage, and further improves the smoothness of the operation of the structure.

[0026] Fifth, the present invention provides a resettable rotating structure between the extrusion top plate and the connection bottom plate, thereby avoiding as much as possible the obstruction of the extrusion component to the displacement of the collection tank, and further ensuring the smoothness of the movement of the collection tank.

[0037] See also Figure 1-6 , the present invention provides the following technical solutions:

[0038] Specifically, it refers to an automatic sand washing cyclone sand remover, comprising a ceramic cyclone cylinder 1 and two supporting bottom plates 5. The outer surface of the ceramic cyclone cylinder 1 is fixedly connected with a feed pipe 2 connected with the interior thereof, and the feed pipe 2 is installed at an eccentric position of the ceramic cyclone cylinder 1. An overflow pipe 3 connected with the interior thereof is fixedly installed on the upper surface of the ceramic cyclone cylinder 1. A sand discharge pipe 4 also connected with the interior thereof is fixedly installed on the lower surface of the ceramic cyclone cylinder 1. The sand-water mixture is transported under pressure and finally transported into the ceramic cyclone cylinder 1 through the feed pipe 2. Since the feed pipe 2 Installed at the eccentric position of the ceramic cyclone cylinder 1, when water passes through the feed pipe 2 of the cyclone desander, it first forms a surrounding fluid obliquely downward along the tangential direction of the ceramic cyclone cylinder 1, and the water flow rotates and moves downward. Due to the different densities of sand and water, under the combined action of centrifugal force, centripetal force, buoyancy and fluid drag, the water with low density rises and is discharged through the overflow pipe 3, while the sand and gravel fall into the sand discharge pipe 4 along the cone wall under the action of fluid inertia centrifugal force and its own gravity. At the same time, a component is provided at the lower part of the ceramic cyclone cylinder 1 to prevent debris from floating upward.

[0039] Two collecting tanks 6 for collecting sand discharged from the discharge pipe 4 are arranged on the upper side of the two supporting bottom plates 5, and a butterfly valve for discharging is arranged at the bottom of the collecting tank 6. The two supporting bottom plates 5 are arranged horizontally and parallelly, and two supporting slide rails 12 are fixedly connected to the upper surfaces of the two supporting bottom plates 5, and two slide rail joints 13 are fixedly connected to the lower surface of the collecting tank 6. The collecting tank 6 slides on the supporting slide rails 12 through the slide rail joints 13. A connecting plate 7 is fixedly connected between the two collecting tanks 6, so that the two collecting tanks 6 can move synchronously. A fixing plate 14 is fixedly installed on the left side of the two supporting bottom plates 5, and a hydraulic cylinder 15 is fixedly installed on the left side of the fixing plate 14. One end of the telescopic rod of the hydraulic cylinder 15 slides through the fixing plate 14 and is in contact with the collecting tank 6. The outer surface is fixedly connected, and a sensor for detecting the amount of sand and gravel accumulation is provided in the collecting tank 6, and the sensor is electrically connected to the hydraulic cylinder 15. Therefore, when the sensor detects that one of the sand and gravel is full, the hydraulic cylinder 15 pulls or pushes the two collecting tanks 6 to move on the supporting bottom plate 5, so that the other collecting tank 6 is moved to the bottom of the sand discharge pipe 4, so that the sand and gravel in the sand discharge pipe 4 can fall into the new collecting tank 6, and the butterfly valve at the bottom of the other full collecting tank 6 is automatically opened to discharge the cleaned sand and gravel in the collecting tank 6. The above structure can clean the sand and gravel accumulated in the collecting tank 6 without stopping the cyclone sand remover, thereby further improving the cleaning efficiency and speed of the sand and gravel.

[0040] A docking ring 8 is provided on the collection tank 6, and a telescopic hose 10 is fixedly installed between the lower surface of the docking ring 8 and the collection tank 6, and the opening of the collection tank 6 is located on the inner side of the telescopic hose 10, and a lifting mechanism 9 for controlling the rise of the docking ring 8 is provided on the outer surface of the collection tank 6. In this way, when the collection tank 6 is displaced to the right below the sand discharge pipe 4, the lifting mechanism 9 automatically operates to control the docking ring 8 to move downward and fit with the lower side of the sand discharge pipe 4, so as to avoid the gap between the sand discharge pipe 4 and the collection tank 6, resulting in the sand and gravel splashing out of the collection tank 6, thereby ensuring the collection effect of the sand and gravel. The sealing component is blocked internally, so that when the collecting tank 6 moves out of the lower side of the sand discharge pipe 4, the sealing component automatically seals the inside of the sand discharge pipe 4, thereby preventing the separated sand and gravel from falling out of the sand discharge pipe 4 during the continuous operation of the cyclone desander. The upper surface of the docking ring 8 is provided with an extrusion component 11 for controlling the sealing component, so that when the docking ring 8 moves up and fits the lower surface of the sand discharge pipe 4, the extrusion component 11 controls the sealing component to open, so that the sand and gravel accumulated in the sand discharge pipe 4 falls into the collecting tank 6. Through the above structure, the sand and gravel in the collecting tank 6 can be cleaned without stopping the cyclone desander.

[0041] The lifting mechanism 9 includes two mounting plates 901, which are fixedly mounted on the outer surface of the collection tank 6 in a vertically parallel manner. A connecting slide bar 902 is fixedly connected between the two mounting plates 901. A sleeve slide plate 903 is slidably sleeved on the outer surface of the connecting slide bar 902. An L-shaped push rod 905 is fixedly connected to the upper surface of the sleeve slide plate 903. One end of the top cross bar of the L-shaped push rod 905 is fixedly connected to the outer surface of the docking ring 8. The lower surface of the sleeve slide plate 903 is fixedly connected to the lower mounting plate 901. A second tension spring 904 is fixedly connected therein, and the second tension spring 904 is movably sleeved on the outer surface of the connecting slide rod 902. When the second tension spring 904 is not affected by the tension force, the tension spring 904 will generate tension on the sleeve slide 903, so that the sleeve slide 903 is at the bottom, so that the L-shaped push rod 905 pulls the docking ring 8 to the side close to the collecting tank 6. Therefore, when the collecting tank 6 moves toward the bottom of the sand discharge pipe 4, the docking ring 8 will not collide with the sand discharge pipe 4, further ensuring the stability of the collecting tank 6 during displacement.

[0042] The outer surface of the collecting tank 6 is fixedly connected with a limiting slide bar 907, and the limiting slide bar 907 is located at the lower side of the mounting plate 901. The other end of the limiting slide bar 907 is slidably sleeved with a contact rod 906. The end of the contact rod 906 away from the limiting slide bar 907 is hemispherical, and a rotating push plate 908 is hinged between the upper surface of the contact rod 906 and the lower surface of the sleeve slide plate 903. The upper surface of the supporting bottom plate 5 is fixedly connected with a fixed extrusion block 909. The shape of the fixed extrusion block 909 is an isosceles triangle, and the end of the contact rod 906 away from the limiting slide bar 907 contacts the inclined surface of the fixed extrusion block 909. At the same time, the fixed extrusion block 909 and the sand discharge pipe 4 are in the same horizontal position. Therefore, when the collecting tank 6 moves to the side close to the sand discharge pipe 4, the contact rod 906 contacts the inclined surface of the fixed extrusion block 909, so that the inclined surface of the fixed extrusion block 909 will contact the contact rod 906 forms a thrust, causing the contact rod 906 to move toward the side close to the collecting tank 6. At the same time, rotating the push plate 908 will cause the sleeve slide 903 to move upward. At the same time, the second tension spring 904 is stretched by force, causing the docking ring 8 to move upward synchronously. When the collecting tank 6 moves to the bottom of the sand discharge pipe 4, the contact rod 906 moves to the top of the fixed extrusion block 909. At this time, the contact rod 906 moves to the maximum distance, so that the docking ring 8 fits the lower side of the sand discharge pipe 4. When the collecting tank 6 moves to the side away from the sand discharge pipe 4, the fixed extrusion block 909 cannot squeeze the contact rod 906, so that the docking ring 8 moves downward under the pull of the second tension spring 904. The above structure can automatically control the docking ring 8 to move upward or downward during the movement of the collecting tank 6 to the specified position without manual control, which greatly improves the automation of the device.

[0043] The sealing assembly includes a rotating shaft 401, and the two ends of the rotating shaft 401 are rotatably connected to the inner walls of the sand discharge pipe 4 on both sides. The outer surface of the rotating shaft 401 is fixedly sleeved with a sealing baffle 402 for sealing the inside of the sand discharge pipe 4. At the same time, the outer surface of the sealing baffle 402 is sleeved with a sealing rubber ring for increasing the sealing performance between the sealing baffle 402 and the inner wall of the sand discharge pipe 4.

[0044] The outer surface of the sand discharge pipe 4 is fixedly connected with an external shell 403, and one end of the rotating shaft 401 close to the external shell 403 rotates and penetrates into the external shell 403. A worm gear 404 is fixedly sleeved on one end of the rotating shaft 401 located at the external shell 403, and a worm 405 is meshingly connected to the side of the worm gear 404. The upper end of the worm 405 is rotatably connected to the top wall of the external shell 403, and the lower end of the worm 405 is fixedly connected to a gear 406, and one side of the gear 406 is meshingly connected to a rack 407. A guide rail 408 for supporting the rack 407 is fixedly connected to the bottom wall of the external shell 403, and the rack 407 is slidably connected to the guide rail 408. A trigger rod 409 is fixedly connected to the side of the rack 407, and the other end of the trigger rod 409 slides through the external shell 403. On the outer surface, a first tension spring 410 is fixedly connected between the rack 407 and the inner wall of the external shell 403. The first tension spring 410 is movably sleeved on the outer surface of the trigger rod 409. When the first tension spring 410 is not affected by the tension force, the first tension spring 410 pulls the rack 407, so that the initial position of the rack 407 is close to one side of the worm gear 404, and at the same time, the initial state of the sealing baffle 402 is horizontal, and the inner wall of the sand discharge pipe 4 is sealed. At the same time, the component uses a worm gear to drive the sealing baffle 402. Since the worm gear has a self-locking effect, when the sealing baffle 402 is horizontal and sand and gravel continue to fall onto the sealing baffle 402, the sealing baffle 402 is restricted by the self-locking effect and will not rotate, thereby further ensuring the use effect of the sealing component.

[0045] The extrusion assembly 11 includes a connecting bottom plate 1101, which is fixedly mounted on the upper surface of the docking ring 8. An extrusion top plate 1102 is provided on the upper side of the connecting bottom plate 1101. The shape of the extrusion top plate 1102 is a right-angled trapezoid. One end of the trigger rod 409 located outside the external shell 403 contacts the inclined surface of the extrusion top plate 1102. When the docking ring 8 moves upward, the extrusion assembly 11 moves upward synchronously with the docking ring 8, so that the inclined surface of the extrusion top plate 1102 contacts the trigger rod 409, thereby pushing the trigger rod 409 to move to one side inside the external shell 403, and the rack 407 moves with the trigger rod. 409 is synchronously displaced, and at the same time, the first tension spring 410 is stretched, the rack 407 synchronously drives the gear 406 to rotate, and the worm 405 rotates synchronously with the gear 406, so the worm 405 synchronously drives the worm wheel 404 to rotate, and the rotating shaft 401 drives the sealing baffle 402 to rotate ninety degrees, so that the sealing baffle 402 no longer blocks the sand discharge pipe 4, so the sand and gravel in the sand discharge pipe 4 falls into the collection tank 6 through the sand discharge pipe 4, and the extrusion assembly 11 can automatically open the sealing assembly after the docking ring 8 rises, which has a higher linkage and further improves the smoothness of the operation of the structure.

[0046] A rotating groove 1104 is provided on the connecting bottom plate 1101, and a mounting shaft 1105 is fixedly connected between the inner walls of the rotating groove 1104 on both sides opposite to each other. A rotating plate 1103 is fixedly connected to the lower surface of the extruding top plate 1102, and a mounting hole 1106 is provided on the rotating plate 1103. The rotating plate 1103 is rotatably sleeved on the outer surface of the mounting shaft 1105 through the mounting hole 1106. At the same time, a torsion spring 1107 is provided between the rotating plate 1103 and the mounting shaft 1105, and one end of the torsion spring 1107 is fixed to the rotating plate 1103, and the other end is fixed to the mounting shaft 1105. In this way, under the action of the torsion spring 1107, the extruding top plate 1102 and the connecting bottom plate 1102 are connected. 01 is in a vertical shape, and the strength of the torsion spring 1107 is greater than the strength of the first tension spring 410. Therefore, when the extrusion top plate 1105 squeezes the trigger rod 409, the extrusion top plate 1102 will not rotate, which ensures the stability of the extrusion top plate 1102 when pushing the trigger rod 409 to move. When the collecting tank 6 moves to the side away from the sand discharge pipe 4, the extrusion top plate 1102 will squeeze the outer surface of the external shell 403, so that the extrusion top plate 1102 rotates on the connecting bottom plate 1101, and the torsion spring 1107 is forced to shrink. This method is used to avoid the extrusion component 11 from blocking the displacement of the collecting tank 6 as much as possible, and further ensure the smoothness of the movement of the collecting tank 6.

[0047] The working principle of the automatic sand washing cyclone desander provided by the present invention is as follows:

[0048] In the first step, the sand-water mixture is transported under pressure and finally transported to the ceramic cyclone cylinder 1 through the feed pipe 2. Since the feed pipe 2 is installed at the eccentric position of the ceramic cyclone cylinder 1, when the water passes through the feed pipe 2 of the cyclone desander, it first forms a surrounding fluid that is obliquely downward along the tangential direction of the ceramic cyclone cylinder 1. The water flow rotates and moves downward. Due to the different densities of sand and water, under the combined action of centrifugal force, centripetal force, buoyancy and fluid drag, the water with low density rises and is discharged through the overflow pipe 3. The sand and gravel fall into the sand discharge pipe 4 along the cone wall under the action of the fluid inertia centrifugal force and its own gravity, and then fall into the collection tank 6;

[0049] Step 2: When the sensor detects that one of the sand and gravel collection tanks is full, the hydraulic cylinder 15 pulls or pushes the two collection tanks 6 to move on the supporting bottom plate 5, so that the other collection tank 6 moves to the bottom of the sand discharge pipe 4, so that the sand and gravel in the sand discharge pipe 4 can fall into the new collection tank 6, and the butterfly valve at the bottom of the other full collection tank 6 automatically opens;

[0050] Step 3: When the collecting tank 6 moves further away from the sand discharge pipe 4, the fixed extrusion block 909 cannot squeeze the contact rod 906, so that the docking ring 8 moves downward under the pull of the second tension spring 904, and the extrusion assembly 11 no longer contacts the trigger rod 409. Therefore, the rack 407 moves to the initial position under the pull of the first tension spring 410, so that the sealing baffle 402 rotates to the initial position and blocks the sand discharge pipe 4. At this time, sand and gravel accumulate on the sealing baffle 402.

[0051] Step 4. When a new collecting tank 6 moves toward the side close to the sand discharge pipe 4, the contact rod 906 contacts the inclined surface of the fixed extrusion block 909, so that the inclined surface of the fixed extrusion block 909 will form a thrust on the contact rod 906, so that the contact rod 906 moves toward the side close to the collecting tank 6. At the same time, the rotating push plate 908 will cause the sleeve slide plate 903 to move upward. At the same time, the second tension spring 904 is stretched, so that the docking ring 8 moves upward synchronously. When the collecting tank 6 moves to the bottom of the sand discharge pipe 4, the contact rod 906 moves to the top of the fixed extrusion block 909. At this time, the contact rod 906 moves to the maximum distance, so that the docking ring 8 fits the lower side of the sand discharge pipe 4.

[0052] In the fifth step, during the upward displacement of the docking ring 8, the extrusion assembly 11 is synchronously displaced upward with the docking ring 8, so that the inclined surface of the extrusion top plate 1102 contacts the trigger rod 409, thereby pushing the trigger rod 409 to move to one side inside the external shell 403, and the rack 407 is synchronously displaced with the trigger rod 409. At the same time, the first tension spring 410 is stretched, and the rack 407 synchronously drives the gear 406 to rotate, and the worm 405 rotates synchronously with the gear 406, so the worm 405 synchronously drives the worm wheel 404 to rotate. At this time, the rotating shaft 401 drives the sealing baffle 402 to rotate ninety degrees, so that the sealing baffle 402 no longer blocks the sand discharge pipe 4, so that the sand and gravel in the sand discharge pipe 4 falls into the collection tank 6 through the sand discharge pipe 4.

[0053] The present invention designs a new technical solution according to the above scheme: an automatic sand washing method, the specific operation steps are as follows: S1, the sand-water mixture is conveyed under pressure and finally conveyed to the ceramic cyclone cylinder 1 through the conveying pipe 2. Since the conveying pipe 2 is installed at the eccentric position of the ceramic cyclone cylinder 1, when the water passes through the conveying pipe 2 of the cyclone desander, it first forms a surrounding fluid obliquely downward along the tangential direction of the ceramic cyclone cylinder 1, and the water flow rotates and moves downward. Due to the different densities of sand and water, under the combined action of centrifugal force, centripetal force, buoyancy and fluid drag, the water with low density rises and is discharged through the overflow pipe 3, while the sand and gravel fall into the sand discharge pipe 4 along the cone wall under the action of the fluid inertial centrifugal force and its own gravity, and then fall into the collection tank 6;

[0054] S2. When the sensor detects that one of the sand and gravel is full, the hydraulic cylinder 15 pulls or pushes the two collection tanks 6 to move on the supporting bottom plate 5, so that the other collection tank 6 moves to the bottom of the sand discharge pipe 4, so that the sand and gravel in the sand discharge pipe 4 can fall into the new collection tank 6, and the butterfly valve at the bottom of the other full collection tank 6 automatically opens;

[0055] S3, when the collecting tank 6 moves further away from the sand discharge pipe 4, the fixed extrusion block 909 cannot squeeze the contact rod 906, so that the docking ring 8 moves downward under the pull of the second tension spring 904, and the extrusion assembly 11 no longer contacts the trigger rod 409, so the rack 407 moves to the initial position under the pull of the first tension spring 410, so that the sealing baffle 402 rotates to the initial position and blocks the sand discharge pipe 4, and sand and gravel accumulate on the sealing baffle 402;

[0056] S4. When a new collecting tank 6 moves toward the side close to the sand discharge pipe 4, the contact rod 906 contacts the inclined surface of the fixed extrusion block 909, so that the inclined surface of the fixed extrusion block 909 will form a thrust on the contact rod 906, so that the contact rod 906 moves toward the side close to the collecting tank 6, and at the same time, the rotating push plate 908 will cause the sleeve slide plate 903 to move upward, and at the same time, the second tension spring 904 is stretched, so that the docking ring 8 moves upward synchronously. When the collecting tank 6 moves to the bottom of the sand discharge pipe 4, the contact rod 906 moves to the top of the fixed extrusion block 909. At this time, the contact rod 906 moves to the maximum distance, so that the docking ring 8 fits the lower side of the sand discharge pipe 4;

[0057] S5. During the upward displacement of the docking ring 8, the extrusion assembly 11 is synchronously displaced upward with the docking ring 8, so that the inclined surface of the extrusion top plate 1102 contacts the trigger rod 409, thereby pushing the trigger rod 409 to move to one side inside the external shell 403, and the rack 407 is synchronously displaced with the trigger rod 409. At the same time, the first tension spring 410 is stretched, and the rack 407 synchronously drives the gear 406 to rotate, and the worm 405 rotates synchronously with the gear 406, so the worm 405 synchronously drives the worm wheel 404 to rotate. At this time, the rotating shaft 401 drives the sealing baffle 402 to rotate ninety degrees, so that the sealing baffle 402 no longer blocks the sand discharge pipe 4, so that the sand and gravel in the sand discharge pipe 4 fall into the collection tank 6 through the sand discharge pipe 4.

An automatic sand washing method, based on an automatic sand washing cyclone desander according to any one of claims 1 to 9 above, Features: The specific operation steps are as follows: S1, the sand-water mixture is transported under pressure and finally transported to the ceramic cyclone cylinder 1 through the feed pipe 2. Since the feed pipe (2) is installed at the eccentric position of the ceramic cyclone cylinder (1), when the water passes through the feed pipe (2) of the cyclone desander, it first forms a surrounding fluid that is obliquely downward along the tangential direction of the ceramic cyclone cylinder (1). The water flow rotates and moves downward. Due to the different densities of sand and water, under the combined action of centrifugal force, centripetal force, buoyancy and fluid drag, the water with low density rises and is discharged through the overflow pipe (3), while the sand and gravel fall into the sand discharge pipe (4) along the cone wall under the action of the fluid inertial centrifugal force and its own gravity, and then fall into the collection tank (6); S2. When the sensor detects that one of the sand and gravel tanks is full, the hydraulic cylinder (15) pulls or pushes the two collecting tanks (6) to move on the supporting bottom plate (5), so that the other collecting tank (6) moves to the bottom of the sand discharge pipe (4), so that the sand and gravel in the sand discharge pipe (4) can fall into the new collecting tank (6), and the butterfly valve at the bottom of the other full collecting tank (6) automatically opens; S3. When the collecting tank (6) moves further away from the sand discharge pipe (4), the fixed extrusion block (909) is unable to squeeze the contact rod (906), so that the docking ring (8) moves downward under the pull of the second tension spring (904), and the extrusion assembly (11) no longer contacts the trigger rod (409). Therefore, under the pull of the first tension spring (410), the rack (407) moves to the initial position, so that the sealing baffle (402) rotates to the initial position and blocks the sand discharge pipe (4). At this time, sand and gravel accumulate on the sealing baffle (402); S4. When a new collecting tank (6) is displaced toward the side close to the sand discharge pipe (4), the contact rod (906) contacts the inclined surface of the fixed extrusion block (909), so that the inclined surface of the fixed extrusion block (909) forms a thrust on the contact rod (906), causing the contact rod (906) to be displaced toward the side close to the collecting tank (6). At the same time, the rotating push plate (908) causes the sleeve slide plate (903) to be displaced upward. At the same time, the second tension spring (904) is stretched, causing the docking ring (8) to be displaced upward synchronously. When the collecting tank (6) is displaced to the bottom of the sand discharge pipe (4), the contact rod (906) is displaced to the top of the fixed extrusion block (909). At this time, the contact rod (906) is displaced to the maximum distance, so that the docking ring (8) is in contact with the lower side of the sand discharge pipe (4); S5. During the upward displacement of the docking ring (8), the extrusion assembly (11) moves upward synchronously with the docking ring (8), so that the inclined surface of the extrusion top plate (1102) contacts the trigger rod (409), thereby pushing the trigger rod (409) to move toward one side of the external housing (403), and the rack (407) moves synchronously with the trigger rod (409). At the same time, the first tension spring (410) is stretched, and the rack (407) drives the gear (406) to rotate synchronously, and the worm (405) rotates synchronously with the gear (406), so that the worm (405) drives the worm wheel (404) to rotate synchronously. At this time, the rotating shaft (401) drives the sealing baffle (402) to rotate ninety degrees, so that the sealing baffle (402) no longer blocks the sand discharge pipe (4), so that the sand and gravel in the sand discharge pipe (4) falls into the collection tank (6) through the sand discharge pipe (4).
