Description

Technical Field

[0001] The present application relates to the technical field of semiconductor waste recycling, and in particular to a tin slag recycling system. Background Art

[0002] Tin (Sn), chemical symbol Sn, is a silvery-white metal element belonging to the carbon group. It exists in nature in the form of cassiterite (tin oxide) and can also form alloys with other metals. In the electronics industry, tin is often used as a welding material, called solder. Tools involved in tin welding, gloves, protective clothing and other items are adhered to tin slag, collectively referred to as slag-containing items.

[0003] The existing method of cleaning slag-containing items is to rinse the slag-containing items with water, and the wastewater formed after rinsing is discharged into the industrial wastewater treatment system for sewage treatment, which leads to waste of tin materials. Therefore, it is urgent to develop a new tin slag recovery system. Summary of the invention

[0004] In order to improve the problem of tin material waste, the present application provides a tin slag recovery system.

[0005] The tin slag recovery system provided in this application adopts the following technical solution:

[0006] A tin slag recovery system comprises a cleaning component, a sedimentation component, a water reflux component and a tin slag cleaning component. The cleaning component can use water to clean slag-containing items to form slag-containing water. The sedimentation component is used to receive the slag-containing water flowing out of the cleaning component and precipitate and stratify the slag-containing water to form sediment at the bottom and clean water on the upper layer. The water reflux component is connected to the cleaning component and the sedimentation component to guide the clean water on the upper layer to flow back into the cleaning component. The tin slag cleaning component is used to clean the sediment in the sedimentation component.

[0007] By adopting the above technical scheme, when the tin slag on the slag-containing items is recovered, the slag-containing items are first placed in the cleaning component for cleaning, the tin slag is cleaned into water, and then the slag-containing water is discharged into the sedimentation component. The slag-containing water is allowed to stand in the sedimentation component for sedimentation and stratification, and then the upper layer of clean water is returned to the cleaning component through the water reflux component. The tin slag cleaning component cleans the tin slag at the bottom of the sedimentation component out of the sedimentation tank for recycling, thereby completing the recycling of the tin slag. Recycling can reduce the demand for new tin resources, achieve resource conservation and reuse, and help reduce the exploitation of natural resources and reduce resource consumption.

[0008] In a specific possible implementation scheme, the cleaning component includes a cleaning tank, an ultrasonic cleaning device and a rack. The rack is arranged in the cleaning tank and is used to place objects containing residues. The cleaning tank is filled with cleaning water. The ultrasonic cleaning device can act on the cleaning water to produce a cavitation effect to clean the objects containing residues.

[0009] By adopting the above technical scheme, when cleaning the slag-containing articles, the slag-containing articles are placed in a holding rack, and then ultrasonic waves are generated in water through an ultrasonic cleaning device. When the ultrasonic waves are transmitted into the water, tens of thousands of tiny bubbles are generated. These bubbles are formed in the negative pressure stage of the ultrasonic waves and quickly close in the positive pressure stage. When the bubbles close, shock waves are generated. This shock wave can generate a pressure of up to several thousand atmospheres to impact the surface of the object, thereby cleaning the tin slag attached to the slag-containing articles into the water. By ultrasonic cleaning, the tin slag is separated from the slag-containing articles more thoroughly, thereby improving the recycling rate of the tin slag; at the same time, the slag-containing articles are cleaned more thoroughly.

[0010] In a specific implementation scheme, a driving motor is provided on the cleaning pool, and the driving motor is connected to the object support rack so as to drive the object support rack to rotate in a vertical direction;

[0011] The object support rack is a cylindrical structure, and is provided with an addition port for placing slag-containing objects therein, and is provided with a blocking piece capable of blocking the addition port.

[0012] By adopting the above technical solution, the slag-containing objects are placed into the object receiving rack through the adding port, and then the adding port is blocked by the sealing member, and then the motor is driven to drive the object receiving rack to rotate, thereby increasing the friction between the tin slag on the slag-containing objects and water, which helps the tin slag to fall into the water.

[0013] In a specific possible implementation scheme, the sedimentation component includes a sedimentation tank, the top of which is connected to the bottom of the cleaning tank via a connecting pipe, an inclined surface is provided on the bottom wall of the sedimentation tank, and a conical sedimentation space is formed above the inclined surface.

[0014] By adopting the above technical solution, when the slag-containing water enters the sedimentation tank, the tin slag is accumulated in the sedimentation space at the bottom by standing still, thereby realizing the separation of the tin slag and the upper clean water; the inclined surface is used to guide the accumulation of the tin slag at the bottom of the sedimentation tank, thereby facilitating the cleaning of the tin slag.

[0015] In a specific feasible implementation scheme, the water reflux assembly includes a reflux pipe and a delivery pump, one end of the reflux pipe is connected to the sedimentation tank, and the other end is connected to the cleaning tank. The water inlet of the reflux pipe is located above the highest point of the inclined surface, and the delivery pump is connected in series to the reflux pipe so as to be able to transport the upper clean water in the sedimentation tank to the cleaning tank.

[0016] By adopting the above technical solution, the delivery pump returns the upper clean water to the cleaning tank through the reflux pipe to clean new slag-containing items, thereby saving the adjustment of cleaning water and being conducive to saving water.

[0017] In a specific possible implementation manner, the tin slag cleaning assembly includes a slag cleaning bucket, which is embedded in the inclined surface and forms a conical sedimentation space in the slag cleaning bucket, and the sediment on the inclined surface can slide into the sedimentation space.

[0018] By adopting the above technical solution, the tin slag is settled into the sedimentation space in the slag cleaning bucket in the sedimentation tank, and the slag cleaning bucket is taken out from the sedimentation tank, so that the tin slag in the sedimentation tank is cleaned, thereby improving the convenience of tin slag cleaning.

[0019] In a specific feasible implementation scheme, an intermediate tank is connected in series on the return pipe, and the return pipe includes a first pipe section connected to the delivery pump and a second pipe section connected to the sedimentation tank, the first pipe section and the second pipe section are both inserted into the intermediate tank, and the second pipe section is provided with a water absorbent at one end inserted into the sedimentation tank, and the water inlet of the water absorbent can be moved into the sedimentation space to generate a siphon effect between the intermediate tank and the sedimentation space.

[0020] By adopting the above technical scheme, when the upper clean water is returned to the cleaning tank, the upper clean water in the sedimentation tank flows into the middle tank through the second pipe section, and then the delivery pump delivers the upper clean water in the middle tank to the cleaning tank through the first pipe section; when the water level in the sedimentation tank drops below the water inlet of the second pipe section, the water inlet of the water absorption part moves to the sedimentation space, and the water above the tin slag in the sedimentation space is sucked into the middle tank through the siphon effect, thereby reducing the amount in the slag cleaning bucket, reducing the weight of the slag cleaning bucket, and improving the convenience of moving the slag cleaning bucket out of the sedimentation tank.

[0021] In a specific possible implementation scheme, the water absorbing member includes a base pipe and an adjusting pipe. The base pipe is fixedly arranged at the end of the second pipe section and is vertically arranged on the inclined surface. One end of the adjusting pipe is rotatably sealed and connected to the base pipe so that the rotation plane of the adjusting pipe is parallel to the inclined surface. The water inlet of the adjusting pipe can be rotated into the precipitation space above the tin slag.

[0022] By adopting the above technical solution, as the upper layer of clean water in the sedimentation tank is discharged, the regulating pipe rotates around the base pipe, so that the water inlet end of the regulating pipe is turned above the tin slag in the sedimentation space, thereby discharging excess water in the slag cleaning hopper and reducing the weight of the slag cleaning hopper.

[0023] In a specific possible implementation scheme, a float plate is provided in the sedimentation tank, and the float plate is connected to the regulating tube by a pull rope so as to be able to pull the regulating tube to be located outside the sedimentation space. A counterweight block is provided at the water inlet of the regulating tube, and the counterweight block can pull the regulating tube into the sedimentation space under the action of gravity.

[0024] By adopting the above technical solution, when the slag-containing water is discharged into the sedimentation tank, the water drives the float plate to float up, and the float plate pulls the regulating tube out of the sedimentation space through the pull rope, thereby reducing the influence of the regulating tube on the precipitation of tin slag in the sedimentation space.

[0025] In a specific feasible implementation scheme, a fixed pulley group is provided on the sedimentation tank, and a movable pulley is provided on the slag cleaning bucket. A driving rope is wound around the fixed pulley group and the movable pulley. One end of the driving rope is fixedly connected to the floating plate, and the other end serves as a pulling end. A limiting portion for limiting the upward movement of the floating plate is provided in the sedimentation tank, forming a fixed point for one end of the driving rope. The driving rope can pull the floating plate upward to the limiting portion, so that the regulating tube can be rotated out of the sedimentation space, and the driving rope can pull the slag cleaning bucket to slide out of the sedimentation tank.

[0026] By adopting the above technical solution, when the regulating tube has finished discharging the excess water in the slag cleaning bucket, the operator pulls the pulling end of the driving rope, and the driving rope first pulls the floating plate up to the limiting part to fix the end of the driving rope. At this time, the regulating tube rotates out of the sedimentation space in the slag cleaning bucket, and then continues to pull the driving rope. The driving rope drives the slag cleaning bucket to be pulled out of the sedimentation tank, effectively avoiding the influence of the regulating tube on the upward movement of the slag cleaning bucket, thereby improving the convenience of tin slag recovery.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When recycling the tin slag on the slag-containing items, first place the slag-containing items in the cleaning component for cleaning, wash the tin slag into water, and then discharge the slag-containing water into the sedimentation component. The slag-containing water is allowed to settle and stratify in the sedimentation component, and then the upper layer of clean water is returned to the cleaning component through the water reflux component. The tin slag cleaning component cleans the tin slag at the bottom of the sedimentation component out of the sedimentation tank for recycling, thereby completing the recycling of the tin slag. Recycling can reduce the demand for new tin resources, achieve resource conservation and reuse, and help reduce the exploitation of natural resources and reduce resource consumption;

[0029] 2. As the upper layer of clean water in the sedimentation tank is discharged, the regulating pipe rotates around the base pipe, so that the water inlet end of the regulating pipe is turned to the top of the tin slag in the sedimentation space, thereby discharging the excess water in the slag cleaning bucket and reducing the weight of the slag cleaning bucket;

[0030] 3. When the regulating tube has finished discharging the excess water in the slag cleaning bucket, the operator pulls the pulling end of the driving rope, and the driving rope first pulls the floating plate up to the limit part to fix the end of the driving rope. At this time, the regulating tube rotates out of the sedimentation space in the slag cleaning bucket, and then continues to pull the driving rope. The driving rope drives the slag cleaning bucket out of the sedimentation tank, effectively avoiding the influence of the regulating tube on the upward movement of the slag cleaning bucket, thereby improving the convenience of tin slag recovery.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-8 This application is described in further detail.

[0041] The embodiment of the present application discloses a tin slag recovery system.

[0042] Example 1

[0043] Reference Figure 1 A tin slag recovery system includes a cleaning component 1, a sedimentation component 2, a water reflux component 3 and a tin slag cleaning component 4. The cleaning component 1 uses water to clean slag-containing items to form slag-containing water. The slag-containing water is discharged from the cleaning component 1 to the sedimentation component 2. The slag-containing water is precipitated and layered in the sedimentation component 2 to form sediment at the bottom and clean water on the upper layer. The water reflux component 3 is connected to the cleaning component 1 and the sedimentation component 2, and guides the clean water on the upper layer to flow back into the cleaning component 1 to clean new slag-containing items. The tin slag cleaning component 4 is used to clean the sediment in the sedimentation component 2 and recycle the tin slag.

[0044] When recycling the tin slag on the slag-containing articles, the slag-containing articles are first placed in the cleaning component 1 for cleaning, the tin slag is cleaned into water, and then the slag-containing water is discharged into the precipitation component 2, the slag-containing water is allowed to stand in the precipitation component 2 for sedimentation and stratification, and then the upper layer of clean water is returned to the cleaning component 1 by the water reflux component 3, and the tin slag cleaning component 4 cleans the tin slag at the bottom of the precipitation component 2 out of the sedimentation tank 21 for recycling, thereby completing the recycling of the tin slag. The recycling of the tin slag can reduce the demand for new tin resources, realize resource conservation and reuse, and help reduce the exploitation of natural resources and reduce resource consumption. The stacking and improper treatment of tin slag will cause pollution to the environment, and the recycling of tin slag can reduce the discharge of solid waste and reduce the pressure on the environment. This helps to reduce the occupation of land by industrial waste and the damage to the ecosystem.

[0045] Reference Figure 1 , Figure 2 The cleaning component 1 in this embodiment includes a cleaning tank 11, an ultrasonic cleaning device 12 and a rack 13. The rack 13 in this embodiment is a cylindrical mesh structure, which is horizontally placed in the cleaning tank 11. A driving motor 14 is fixedly provided on the outer wall of the cleaning tank 11. The output shaft of the driving motor 14 passes through the side wall of the cleaning tank 11 and extends into the cleaning tank 11. One end of the rack 13 is fixedly connected to the output shaft of the driving motor 14, and the other end is rotatably connected to the cleaning tank 11 through a rotating shaft, so that the driving motor 14 drives the rack 13 to rotate in the cleaning tank 11.

[0046] Reference Figure 2 The rack 13 is provided with an addition port 131 in the circumference thereof, and slag-containing items can be added into the rack 13 through the addition port 131. The rack 13 is hinged with a blocking piece 132 at the addition port 131. The blocking piece 132 in this embodiment is an arc-shaped mesh plate that fits the rack 13 and is fixed to the rack 13 by bolts, so that the blocking piece 132 blocks the addition port 131.

[0047] When cleaning the slag-containing objects, the slag-containing objects are placed in the object holding rack 13 through the adding port 131, and then the adding port 131 is blocked by the blocking member 132, and then the driving motor 14 drives the object holding rack 13 to rotate, thereby increasing the friction between the tin slag on the slag-containing objects and the water, which helps the tin slag to fall into the water.

[0048] The ultrasonic cleaning device 12 is arranged on the side wall of the cleaning tank 11. The ultrasonic cleaning machine converts electrical energy into high-frequency mechanical vibration through a transducer to generate ultrasonic waves. When ultrasonic waves are transmitted into water, tens of thousands of tiny bubbles are generated. These bubbles are formed in the negative pressure stage of the ultrasonic waves and quickly close in the positive pressure stage. When the bubbles close, shock waves are generated. This shock wave can generate a pressure of up to several thousand atmospheres to impact the surface of the object, thereby cleaning the tin slag attached to the slag-containing items into the water. Through ultrasonic cleaning, the tin slag is separated from the slag-containing items more thoroughly, thereby improving the recycling rate of the tin slag; at the same time, the slag-containing items are cleaned more thoroughly.

[0049] Reference Figure 2 , Figure 3 and Figure 4The sedimentation assembly 2 in this embodiment includes a sedimentation tank 21. The top of the sedimentation tank 21 is connected to the bottom of the cleaning tank 11 through a connecting pipe 22. A valve is provided on the connecting pipe 22 to control the on-off of the connecting pipe 22 so that the slag-containing water in the cleaning tank 11 can flow into the sedimentation tank 21. An inclined surface 23 is provided on the bottom wall of the sedimentation tank 21. There is a height difference between the two sides of the inclined surface 23, so that a conical sedimentation space 24 is formed above the lower side of the inclined surface 23. The tin slag cleaning assembly 4 in this embodiment includes a slag cleaning bucket 41, which is embedded in the inclined surface 23 and forms a conical sedimentation space 24 in the slag cleaning bucket 41. When the slag cleaning bucket 41 is embedded in the inclined surface 23, the bottom wall of the sedimentation space 24 is coplanar with the inclined surface 23, so that the sediment on the inclined surface 23 can slide into the sedimentation space 24. A pull rod 42 arranged in the vertical direction is fixed on the slag cleaning bucket 41, and the pull rod 42 extends out of the sedimentation tank 21. The operator pulls the pull rod 42 to pull the slag cleaning bucket 41 out of the sedimentation tank 21.

[0050] When the slag-containing water enters the sedimentation tank 21, the tin slag accumulates in the sedimentation space 24 of the slag cleaning bucket 41 through standing, thereby separating the tin slag from the upper clean water; the inclined surface 23 is used to guide the accumulation of the tin slag in the sedimentation space 24 in the slag cleaning bucket 41, and then the operator draws the slag cleaning bucket 41 out of the sedimentation tank 21 through the pull rod 42, thereby facilitating the cleaning and recovery of the tin slag.

[0051] Reference Figure 2 , Figure 4 The water return assembly 3 in this embodiment includes a return pipe 31 and a delivery pump 32. One end of the return pipe 31 is connected to the sedimentation tank 21, and the other end is connected to the cleaning tank 11. The water inlet of the return pipe 31 is located at the highest point of the inclined surface 23. The delivery pump 32 is connected in series to the return pipe 31 to deliver the upper layer of clean water in the sedimentation tank 21 to the cleaning tank 11. The delivery pump 32 returns the upper layer of clean water to the cleaning tank 11 through the return pipe 31 to clean new slag-containing objects, thereby saving cleaning water.

[0052] The implementation principle of Example 1 is as follows: when the tin slag on the slag-containing articles is recovered, the slag-containing articles are placed in the object holder 13 through the addition port 131, and then the addition port 131 is blocked by the blocking member 132, and then the driving motor 14 drives the object holder 13 to rotate, and the ultrasonic cleaning device 12 converts the electrical energy into high-frequency mechanical vibration through the transducer to generate ultrasonic waves, cleans the tin slag on the slag-containing articles, and washes the tin slag into water, and then discharges the slag-containing water into the sedimentation tank 21, and the tin slag is accumulated in the sedimentation space 24 of the slag cleaning bucket 41 by standing, and the delivery pump 32 returns the upper layer of clean water to the cleaning tank 11 through the reflux pipe 31, and cleans the new slag-containing articles, and then the operator draws the slag cleaning bucket 41 out of the sedimentation tank 21 through the pull rod 42 to clean and recover the tin slag. From completing the recycling of tin slag, the demand for new tin resources can be reduced through recycling, and resource conservation and reuse can be achieved, which helps to reduce the exploitation of natural resources and reduce resource consumption.

[0053] Example 2

[0054] Reference Figure 5 , Figure 6 The difference between this embodiment and embodiment 1 is that an intermediate tank 5 is connected in series to the return pipe 31, the return pipe 31 includes a first pipe section 311 connected to the delivery pump 32 and a second pipe section 312 connected to the sedimentation tank 21, a valve is connected in series to the second pipe section 312, the highest point of the water level in the intermediate tank 5 is lower than the bottom height of the sedimentation tank 21, the first pipe section 311 and the second pipe section 312 are both inserted into the intermediate tank 5, the upper layer of clean water in the sedimentation tank 21 can flow into the intermediate tank 5 along the second pipe section 312, and the delivery pump 32 delivers the upper layer of clean water in the intermediate tank 5 to the cleaning tank 11 through the first pipe section 311, completing the reflux of the upper layer of clean water.

[0055] Reference Figure 6 , Figure 7, usually under the premise of unknown tin slag content, in order to leave enough space for tin slag to settle at the bottom of the sedimentation tank 21, the height of the water inlet of the second pipe section 312 is greater than the height of the tin slag precipitation. Therefore, a large amount of upper layer of clean water will be stored above the tin slag in the slag cleaning bucket 41, which will increase the weight of the slag cleaning bucket 41 and affect the subsequent drying of the tin slag. Therefore, a water absorbing member 6 is provided at the water inlet end of the second pipe section 312. The water absorbing member 6 in this embodiment includes a base pipe 61 and an adjusting pipe 62. The base pipe 61 is fixedly arranged at the water inlet of the second pipe section 312 and arranged in a direction perpendicular to the inclined surface 23. One end of the adjusting pipe 62 is rotatably connected to the base pipe 61 through a rotating joint, and the opening of the other end is arranged upward, so that the rotation plane formed when the adjusting pipe 62 rotates is parallel to the inclined surface 23. A counterweight block 63 is provided on the free end of the adjusting pipe 62. Driven by the gravity of the counterweight 63, the regulating pipe 62 can rotate from the highest point of the inclined surface 23 to the sedimentation space 24 and stay above the tin slag in the sedimentation space 24. When the water level in the sedimentation tank 21 drops to below the water inlet of the second pipe section 312, the water outlet of the second pipe section 312 is located below the water level of the middle tank 5. The water inlet of the regulating pipe 62 is located in the sedimentation space 24 and below the water level of the sedimentation tank 21, so that a siphon effect is generated between the middle tank 5 and the sedimentation space 24. The water above the water inlet of the regulating pipe 62 flows into the middle tank 5 under the action of the siphon effect, thereby reducing the amount of water in the slag cleaning bucket 41, reducing the weight of the slag cleaning bucket 41, and improving the convenience of moving the slag cleaning bucket 41 out of the sedimentation tank 21.

[0056] Reference Figure 6 , Figure 8 A floating plate 64 is provided on one side of the sedimentation tank 21 close to the second pipe section 312. The floating plate 64 deviates from the top of the regulating tube 62. A guide rod fixedly arranged on the inner wall of the sedimentation tank 21 passes through the floating plate 64 to guide the sliding of the floating plate 64, so as to realize the stable up and down movement of the floating plate 64. The floating plate 64 is arranged outside the sliding track of the slag cleaning bucket 41. A pull rope 65 is fixedly arranged under the floating plate 64. The other end of the pull rope 65 is fixedly connected to the regulating tube 62. A limiting portion 66 is fixedly arranged on the inner wall of the sedimentation tank 21 above the floating plate 64. As the water level in the sedimentation tank 21 rises, the floating plate 64 floats up and drives the regulating tube 62 to rotate through the pull rope 65. When the floating plate 64 abuts against the limiting portion 66, the water inlet of the regulating tube 62 rotates to the highest point, thereby reducing the influence of the regulating tube 62 on the precipitation of tin slag in the sedimentation space 24.

[0057] Reference Figure 6 , Figure 8The sedimentation tank 21 is provided with a fixed pulley group 7. The fixed pulley group 7 in this embodiment includes a first fixed pulley 71, a second fixed pulley 72, a third fixed pulley 73, a fourth fixed pulley 74, and a fifth fixed pulley 75. A guide groove 211 arranged in a vertical direction is opened on the inner wall of the sedimentation tank 21. A guide block 411 sliding in the guide groove 211 is provided on the slag cleaning bucket 41. The first fixed pulley 71 and the second fixed pulley 72 are both rotatably arranged above the sedimentation tank 21. The second fixed pulley 72, the third fixed pulley 73, the fourth fixed pulley 74, and the fifth fixed pulley 75 are respectively rotatably arranged in the sedimentation tank. At the four corners on the outside of the sedimentation tank 21, the seventh fixed pulley is rotatably arranged above the floating plate 64, the movable pulley 8 is rotatably connected to the slag cleaning bucket 41, and the fixed pulley group 7 and the movable pulley 8 are jointly wound with a driving rope 76, one end of the driving rope 76 passes through the first fixed pulley 71, the movable pulley 8, the second fixed pulley 72, the third fixed pulley 73, the fourth fixed pulley 74, and the fifth fixed pulley 75 in sequence, and then is fixed to the floating plate 64, and the other end of the driving rope 76 is the pulling end 77, and initially, the pulling end 77 is in a relaxed state, so that the floating plate 64 can move downward as the water level in the sedimentation tank 21 drops. When the floating plate 64 abuts against the limiting portion 66, the end of the driving rope 76 is fixed.

[0058] When the regulating tube 62 has finished discharging the excess water in the slag cleaning bucket 41, the operator pulls the pulling end 77 of the driving rope 76, and the driving rope 76 first pulls the floating plate 64 upward to the limiting portion 66 to fix the end of the driving rope 76. At this time, the regulating tube 62 rotates out of the sedimentation space 24 in the slag cleaning bucket 41, and then continues to pull the driving rope 76. The driving rope 76 drives the slag cleaning bucket 41 to be pulled out of the sedimentation tank 21, effectively avoiding the influence of the regulating tube 62 on the upward movement of the slag cleaning bucket 41, thereby improving the convenience of tin slag recovery.

[0059] The implementation principle of Example 2 is as follows: when the water level in the sedimentation tank 21 drops to below the water inlet of the second pipe section 312, the water outlet of the second pipe section 312 is located below the water level of the middle tank 5, and the water inlet of the regulating pipe 62 is located in the sedimentation space 24 and below the water level of the sedimentation tank 21, so that a siphon effect is generated between the middle tank 5 and the sedimentation space 24, and the water above the water inlet of the regulating pipe 62 flows into the middle tank 5 under the action of the siphon effect, thereby reducing the amount of water in the slag cleaning bucket 41, reducing the weight of the slag cleaning bucket 41, and improving the convenience of moving the slag cleaning bucket 41 out of the sedimentation tank 21.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
