Description

Technical Field

[0001] The invention relates to the technical field of stirring and mixing equipment, in particular to a three-stage stirring, mixing, clarifying and extracting tank. Background Art

[0002] The mixed clarification extraction tank has become the most widely used extraction and separation equipment at home and abroad due to its simple structure and easy operation. However, during its operation, there are problems such as mismatch between clarification and mixing rates, resulting in low extraction and separation efficiency, large material accumulation, and large equipment footprint. The research and design of many mixed clarification extraction tanks with different internal structures are all aimed at effectively improving the extraction efficiency. Among them, the above equipment is also commonly used to treat waste sludge batteries and for cobalt and nickel separation.

[0003] However, when stirring inside the clarification extraction tank, the sludge retained inside the extraction tank will stick to the stirring blades, causing the load of the blades themselves to increase. After long-term use, it will affect the separation effect of the equipment. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a three-stage stirring, mixing and clarifying extraction tank, comprising a mixing chamber, a side wall of the mixing chamber is connected through a corridor, and one end of the corridor away from the mixing chamber is connected through a clarifying chamber;

[0005] The stirring mechanism includes a motor fixedly connected to the top of the mixing chamber, the output end of the motor is fixedly connected to a driving rod, the end of the driving rod away from the motor is fixedly connected to a fixed block, five stirring blades are fixedly connected to the side wall of the fixed block, the ends of the five stirring blades away from the fixed block are fixedly connected to a limiting block, and the bottom of the fixed block is fixedly connected to a control component.

[0006] The fan blade cleaning mechanism includes a scraper slidably connected to the outer wall of the stirring blade, the top of the scraper is fixedly connected to a fixed rod, the outer wall of the fixed rod is rotatably connected to a rotating plate, the top of the rotating plate is fixedly connected to a driving fan blade, and the top of the scraper is fixedly connected to a cleaning component.

[0007] Preferably, the fan blade cleaning mechanism also includes a fixed frame fixedly connected to the top of the scraper, two limit rods are fixedly connected to the side wall of the rotating plate, and the ends of the two limit rods away from the rotating plate are fixedly connected to a curved surface block. Taking advantage of the fact that the fan blades themselves will be subjected to greater resistance during stirring, a fan blade cleaning mechanism is arranged inside the equipment. Before use, the mixing chamber is installed in the required position, and it is ensured that the interior of the mixing chamber is filled with the mixed solution, and the curved surface block is inserted into the inner wall of the fixed frame. At this time, the staff turns on the power of the motor, and the motor drives the fixed block and the stirring blades of the side wall to rotate through the driving rod, and a mixing and stirring process is started. At this time, the stirring blades will rotate counterclockwise, forcing the driving blades to come into contact with the external solution, presenting aFigure 4 In the state shown, water flows from Figure 4 When the liquid flows downward from the top of the stirring blade, the driving blade will generate a thrust to the left due to the influence of the rotating plate and the inclination angle of the driving blade. The driving blade drives the scraper to move along the outer wall of the stirring blade toward the fixed block through the rotating plate. During this process, the scraper will clean the outer wall of the stirring blade.

[0008] Preferably, the fan blade cleaning mechanism also includes a spring slide rod slidably connected to the inner walls of the through holes on both sides of the fixed frame, the side walls of the two spring slide rods are fixedly connected with inclined blocks, and the ends of the two spring slide rods away from the inclined blocks are fixedly connected with a shaped rod.

[0009] Preferably, the fan blade cleaning mechanism also includes a pushing rod rotatably connected to one end of the two profile rods away from the spring sliding rod, and the two pushing rods are rotatably connected to one end of the corresponding profile rod. The scraper will drive the compressed rod to contact the side wall of the fixed block during the movement of the scraper. The compressed rod is blocked and forces the pushing rods at both ends to expand to both ends. The pushing rod drives the inclined surface blocks to expand outward synchronously through the profile rod, so that the inclined surface blocks no longer restrict the arc surface blocks. At this time, the external solution continues to impact the driving blades, forcing the driving blades to swing around the fixed rod. At this time Figure 5 The arc block in the middle will follow the swing of the driving blades and contact the inclined block at the other end, and the arc surface of the arc block will contact the inclined surface of the inclined block. Finally, the arc block breaks through the restriction of the inclined block, so that the other inclined block restricts the rotation of the driving blades. At this time, the direction of the driving blades changes. When the external water flow contacts the driving blades, it will push the driving blades to move outward. The driving blades drive the scraper to move outward along the outer wall of the stirring blades through the rotating plate, and the outer wall of the stirring blades is cleaned for the second time. Through the application of the above components, the stirring blades can remove large pieces of sludge stuck to the outer wall of the stirring blades by sliding the scraper back and forth when stirring, so as to avoid the sludge being adsorbed on the outer wall of the stirring blades and affecting the mixing efficiency of the equipment.

[0010] Preferably, the control component includes a gear rotatably connected to the bottom of the fixed block, the bottom of the fixed block is fixedly connected to five sliding frames, the inner wall of the sliding frame is slidably connected to a gear rod, the side wall of the gear rod is fixedly connected to an arc-shaped fixed rod, the top of the arc-shaped fixed rod is fixedly connected to a support frame, and the end of the support frame away from the arc-shaped fixed rod is fixedly connected to the bottom of the scraper. Utilizing the characteristic that the scraper slides along the outer wall of the stirring fan blade, a control component is arranged on the inner wall of the equipment. When the scraper moves outward, the gear rod is driven by the support frame through the arc-shaped fixed rod to slide outward along the inner wall of the sliding frame. At this time, the gear rod will drive the gear to rotate. In this process, the number of rotations of the gear will indirectly control the length and speed of the outward extension of multiple gear rods, and indirectly control the outward extension length of multiple support frames and scrapers. Through the application of the above-mentioned components, the device can control the specific position of the fan blade cleaning mechanism on the stirring fan blade and the sliding speed during the mixing and stirring process to avoid changes in the positions of each fan blade cleaning mechanism, which causes the center of gravity of the rotation of the stirring fan blade to shift, affecting the rotation efficiency of the equipment.

[0011] Preferably, the cleaning component includes a fixed plate fixedly connected to the side wall of the scraper, a hydraulic cylinder fixedly connected to the side wall of the fixed plate, and one end of the hydraulic cylinder away from the fixed plate is fixedly connected to the side wall of the rotating plate. The above-mentioned gear is used to control the sliding of multiple scrapers. During the rotation of the fixed block, the force of the multiple scrapers sliding outward or inward is transmitted to the gear through the corresponding gear rod, and the gear will collect the force of the movement of multiple scrapers to produce self-rotation; if there are larger impurities in the solution at this time and they stick to the outer wall of one of the stirring blades, the corresponding scraper will be blocked and unable to move. At this time, the gear collects the force transmitted by multiple gear rods and acts on the position of the blocked gear rod, forcing the gear rod to generate a larger thrust outward, forcing the corresponding scraper to push outward, thereby removing large impurities stuck to the outer wall of the stirring blade. Through the application of the above-mentioned components, large impurities can be prevented from affecting the cleaning effect of the equipment.

[0012] Preferably, the cleaning assembly also includes two storage boxes fixedly connected to the side walls of the driving fan blades, the tops of the two storage boxes are connected through a connecting pipe, and the side wall of the gear rod is meshingly connected with the side wall of the gear.

[0013] Preferably, the cleaning component also includes a hydraulic telescopic rod connected through the side wall of the storage box, an impurity scraper is fixedly connected to the end of the hydraulic telescopic rod away from the storage box, a delivery pipe is connected through the side wall of the storage box, and the delivery pipe is connected through the side wall of the hydraulic cylinder away from the power supply of the storage box. Utilizing the above-mentioned characteristics of driving the fan blades to rotate, a cleaning component is arranged inside the equipment. When the driving fan blades rotate, the distance between the rotating plate and the fixed plate will be reduced. During this process, the hydraulic cylinder will be subjected to pressure and force the internal solution to be transmitted to the inside of the storage box through the delivery pipe. The increase in the solution inside the storage box forces multiple hydraulic telescopic rods to expand to both ends. At this time, the hydraulic telescopic rod drives the impurity scraper to move outward along the outer wall of the driving fan blade, so that the impurity scraper scratches and cleans the outer wall of the driving fan blade. Through the application of the above-mentioned components, impurities can be prevented from sticking to the outer wall of the driving fan blade and affecting the swinging speed of the driving fan blade.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention utilizes the characteristic that the fan blades themselves will bear greater resistance during stirring, and a fan blade cleaning mechanism is provided inside the device. Before use, the mixing chamber is installed at the desired position, and it is ensured that the interior of the mixing chamber is filled with the mixed solution, and the arc block is inserted into the inner wall of the fixed frame. At this time, the staff turns on the power of the motor, and the motor drives the fixed block and the stirring fan blades of the side wall to rotate through the driving rod, and a mixing and stirring process is started. At this time, the stirring fan blades will rotate counterclockwise, forcing the driving fan blades to come into contact with the external solution, presenting a Figure 4 In the state shown, water flows from Figure 4 When the liquid flows downward from the top of the mixing blade, the driving blade will generate a thrust to the left due to the influence of the rotating plate and the inclination angle of the driving blade. The driving blade drives the scraper to move along the outer wall of the mixing blade toward the fixed block through the rotating plate. In this process, the scraper will clean the outer wall of the mixing blade. During the movement of the scraper, the scraper will drive the pressure rod to contact the side wall of the fixed block. The pressure rod is blocked and forces the push rods at both ends to expand toward both ends. The push rod drives the inclined surface block to expand outward synchronously through the L-shaped rod, so that the inclined surface block no longer restricts the arc surface block. At this time, the external solution continues to impact the driving blade, forcing the driving blade to swing around the fixed rod. At this time Figure 5The arc block in the middle will follow the swing of the driving blades and contact the inclined block at the other end, and the arc surface of the arc block will contact the inclined surface of the inclined block. Finally, the arc block breaks through the restriction of the inclined block, so that the other inclined block restricts the rotation of the driving blades. At this time, the direction of the driving blades changes. When the external water flow contacts the driving blades, it will push the driving blades to move outward. The driving blades drive the scraper to move outward along the outer wall of the stirring blades through the rotating plate, and the outer wall of the stirring blades is cleaned for the second time. Through the application of the above components, the stirring blades can remove large pieces of sludge stuck to the outer wall of the stirring blades by sliding the scraper back and forth when stirring, so as to avoid the sludge being adsorbed on the outer wall of the stirring blades and affecting the mixing efficiency of the equipment.

[0016] (2) The present invention utilizes the characteristic that the scraper slides along the outer wall of the stirring blade, and a control component is arranged on the inner wall of the equipment. When the scraper moves outward, the support frame drives the gear rod to slide outward along the inner wall of the sliding frame through the arc-shaped fixed rod. At this time, the gear rod will drive the gear to rotate. In this process, the number of rotations of the gear will indirectly control the length and speed of the outward extension of multiple gear rods, and indirectly control the outward extension length of multiple support frames and scrapers. Through the application of the above-mentioned components, the device can control the specific position of the blade cleaning mechanism on the stirring blade and the sliding speed during the mixing and stirring process, so as to avoid the position of each blade cleaning mechanism changing, resulting in the center of gravity of the stirring blade rotating being offset, affecting the rotation efficiency of the equipment.

[0017] (3) The present invention utilizes the characteristic of the above-mentioned gear to control the sliding of multiple scrapers. During the rotation of the fixed block, the force of the multiple scrapers sliding outward or inward is transmitted to the gear through the corresponding gear rod, and the gear will collect the force of the multiple scrapers moving to generate self-rotation; if there are larger impurities in the solution at this time and they stick to the outer wall of one of the stirring blades, the corresponding scraper will be blocked and unable to move. At this time, the gear collects the force transmitted by the multiple gear rods and acts on the position of the blocked gear rod, forcing the gear rod to generate a larger thrust outward, forcing the corresponding scraper to push outward, thereby removing the large impurities stuck to the outer wall of the stirring blade. Through the application of the above-mentioned components, it is prevented that large impurities affect the cleaning effect of the equipment.

[0018] (4) The present invention utilizes the above-mentioned characteristic of the rotation of the driving blades and is provided with a cleaning component inside the device. When the driving blades rotate, the distance between the rotating plate and the fixed plate will be reduced. During this process, the hydraulic cylinder will be subjected to pressure and force the internal solution to be transmitted to the inside of the storage box through the delivery pipe. The increase in the solution inside the storage box forces multiple hydraulic telescopic rods to expand to both ends. At this time, the hydraulic telescopic rods drive the impurity scraper to move outward along the outer wall of the driving blades, so that the impurity scraper scratches and cleans the outer wall of the driving blades. Through the application of the above-mentioned components, it is possible to prevent impurities from sticking to the outer wall of the driving blades and affecting the swinging speed of the driving blades.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] For example, see Figure 1 - Figure 5 The present invention is a three-stage stirring, mixing and clarifying extraction tank, comprising a mixing chamber 1, a side wall of the mixing chamber 1 is connected through a passage 11, and an end of the passage 11 away from the mixing chamber 1 is connected through a clarifying chamber 12;

[0033] The stirring mechanism 2 includes a motor 21 fixedly connected to the top of the mixing chamber 1, the output end of the motor 21 is fixedly connected to a driving rod 22, the end of the driving rod 22 away from the motor 21 is fixedly connected to a fixed block 23, five stirring blades 24 are fixedly connected to the side wall of the fixed block 23, the ends of the five stirring blades 24 away from the fixed block 23 are fixedly connected to a limiting block 25, and the bottom of the fixed block 23 is fixedly connected to a control component 4.

[0034] The fan blade cleaning mechanism 3 includes a scraper 31 slidably connected to the outer wall of the stirring blade 24, the top of the scraper 31 is fixedly connected to a fixed rod 312, the outer wall of the fixed rod 312 is rotatably connected to a rotating plate 32, the top of the rotating plate 32 is fixedly connected to a driving fan blade 33, and the top of the scraper 31 is fixedly connected to a cleaning component 5.

[0035] The fan blade cleaning mechanism 3 also includes a fixing frame 34 fixedly connected to the top of the scraper 31, and two limit rods 35 are fixedly connected to the side wall of the rotating plate 32. The two limit rods 35 are fixedly connected to the end away from the rotating plate 32 with a curved block 36. The fan blades themselves will be subjected to greater resistance during stirring, and a fan blade cleaning mechanism 3 is arranged inside the device. Before use, the mixing chamber 1 is installed in the required position, and it is ensured that the mixing chamber 1 is filled with mixed solution, and the curved block 36 is inserted into the inner wall of the fixing frame 34. At this time, the staff turns on the power of the motor 21, and the motor 21 drives the fixing block 23 and the stirring blades 24 on the side wall to rotate through the driving rod 22, and a mixing and stirring process is started. At this time, the stirring blades 24 will rotate counterclockwise, forcing the driving blades 33 to come into contact with the external solution, presenting as shown in the figure. Figure 4 In the state shown, water flows from Figure 4When the liquid flows downward from the top of the stirring blade 24, the driving blade 33 will generate a thrust to the left due to the influence of the rotating plate 32 and the inclination angle of the driving blade 33. The driving blade 33 drives the scraper 31 to move along the outer wall of the stirring blade 24 toward the fixed block 23 through the rotating plate 32. During this process, the scraper 31 will clean the outer wall of the stirring blade 24.

[0036] The fan blade cleaning mechanism 3 also includes a spring slide bar 37 slidably connected to the inner walls of the through holes on both sides of the fixed frame 34, and the side walls of the two spring slide bars 37 are fixedly connected to a ramp block 38, and the ends of the two spring slide bars 37 away from the ramp block 38 are fixedly connected to an L-shaped rod 39.

[0037] The fan blade cleaning mechanism 3 also includes a push rod 310 rotatably connected to one end of the two L-shaped rods 39 away from the spring slide rod 37, and the two push rods 310 are rotatably connected to one end of the L-shaped rod 39 away from the corresponding L-shaped rod 39 with a pressure rod 311. During the movement of the scraper 31, the scraper 31 will drive the pressure rod 311 to contact the side wall of the fixed block 23. The pressure rod 311 is blocked and forces the push rods 310 at both ends to expand to both ends. The push rod 310 drives the inclined surface block 38 to expand outward synchronously through the L-shaped rod 39, so that the inclined surface block 38 no longer restricts the arc surface block 36. At this time, the external solution continues to impact the driving fan blade 33, forcing the driving fan blade 33 to swing around the fixed rod 312 as the center. At this time Figure 5 The arc block 36 in the middle will follow the swing of the driving blade 33 and contact the inclined block 38 at the other end, and the arc surface of the arc block 36 will contact the inclined surface of the inclined block 38. Finally, the arc block 36 breaks through the restriction of the inclined block 38, so that the other inclined block 38 restricts the rotation of the driving blade 33. At this time, the direction of the driving blade 33 changes. When the external water flow contacts the driving blade 33, it will push the driving blade 33 to move outward, and the driving blade 33 drives the scraper 31 to move outward along the outer wall of the stirring blade 24 through the rotating plate 32, and the outer wall of the stirring blade 24 is cleaned twice. Through the application of the above-mentioned components, the stirring blade 24 can remove large pieces of sludge stuck to the outer wall of the stirring blade 24 by the back and forth sliding of the scraper 31 when stirring, so as to avoid the sludge being adsorbed on the outer wall of the stirring blade 24 and affecting the mixing efficiency of the equipment.

[0038] For example 2, please refer to Figure 6 - Figure 8The present invention is a three-stage stirring, mixing and clarifying extraction tank. On the basis of Example 1, the control component 4 includes a gear 41 rotatably connected to the bottom of the fixed block 23, and five sliding frames 42 are fixedly connected to the bottom of the fixed block 23. The inner wall of the sliding frame 42 is slidably connected with a gear rod 43, and the side wall of the gear rod 43 is fixedly connected with an arc-shaped fixed rod 44. The top of the arc-shaped fixed rod 44 is fixedly connected with a support frame 45, and one end of the support frame 45 away from the arc-shaped fixed rod 44 is fixedly connected to the bottom of the scraper 31. Utilizing the characteristic that the scraper 31 slides along the outer wall of the stirring blade 24, a control component 4 is arranged on the inner wall of the device. When the scraper 31 moves outward, The support frame 45 drives the gear rod 43 to slide outward along the inner wall of the sliding frame 42 through the arc-shaped fixed rod 44. At this time, the gear rod 43 will drive the gear 41 to rotate. In this process, the number of revolutions of the gear 41 will indirectly control the length and speed of the outward extension of multiple gear rods 43, and indirectly control the outward extension length of multiple support frames 45 and scrapers 31. Through the application of the above-mentioned components, the device can control the specific position of the fan blade cleaning mechanism 3 on the stirring blade 24 and the sliding speed during the mixing and stirring process, so as to avoid changes in the position of each fan blade cleaning mechanism 3, which will cause the center of gravity of the stirring blade 24 to shift, affecting the rotation efficiency of the equipment.

[0039] The cleaning assembly 5 includes a fixed plate 51 fixedly connected to the side wall of the scraper 31, and a hydraulic cylinder 52 is fixedly connected to the side wall of the fixed plate 51. The end of the hydraulic cylinder 52 away from the fixed plate 51 is fixedly connected to the side wall of the rotating plate 32. The gear 41 is used to control the sliding of multiple scrapers 31. During the rotation of the fixed block 23, the force of the multiple scrapers 31 sliding outward or inward is transmitted to the gear 41 through the corresponding gear rod 43, and the gear 41 will collect the force of the multiple scrapers 31 moving to generate self-rotation; if there are large impurities in the solution at this time and they are adhered to the outer wall of one of the stirring blades 24, the corresponding scraper 31 will be blocked and unable to move. At this time, the gear 41 collects the force transmitted by the multiple gear rods 43 and acts on the position of the blocked gear rod 43, forcing the gear rod 43 to generate a larger thrust outward, forcing the corresponding scraper 31 to push outward, and remove the large impurities adhered to the outer wall of the stirring blade 24. Through the application of the above-mentioned components, it is prevented that large impurities affect the cleaning effect of the equipment.

[0040] The cleaning assembly 5 further comprises two storage boxes 53 fixedly connected to the side walls of the driving blades 33 , the tops of the two storage boxes 53 are connected through a connecting pipe 54 , and the side walls of the gear rod 43 are meshedly connected with the side walls of the gear 41 .

[0041] The cleaning component 5 also includes a hydraulic telescopic rod 55 connected through the side wall of the storage box 53, and an impurity scraper 56 is fixedly connected to the end of the hydraulic telescopic rod 55 away from the storage box 53. A delivery pipe 57 is connected through the side wall of the storage box 53, and the delivery pipe 57 is connected through the side wall of the hydraulic cylinder 52 away from the power supply of the storage box 53. Utilizing the above-mentioned characteristics of driving the fan blades 33 to rotate, a cleaning component 5 is arranged inside the equipment. When the driving fan blades 33 rotate, the distance between the rotating plate 32 and the fixed plate 51 will be reduced. In this process, the hydraulic cylinder 52 will be subjected to pressure and force the internal solution to be transmitted to the inside of the storage box 53 through the delivery pipe 57. The increase in the internal solution of the storage box 53 forces multiple hydraulic telescopic rods 55 to expand to both ends. At this time, the hydraulic telescopic rod 55 drives the impurity scraper 56 to move outward along the outer wall of the driving fan blade 33, so that the impurity scraper 56 scratches and cleans the outer wall of the driving fan blade 33. Through the application of the above-mentioned components, it is avoided that impurities stick to the outer wall of the driving fan blade 33 and affect the swinging speed of the driving fan blade 33.

[0042] A specific application of this embodiment is: before use, the mixing chamber 1 is installed at a desired position and ensures that the external mixed solution passes through Figure 1 The pipe of middle G enters the mixing chamber 1, and the arc block 36 is inserted into the inner wall of the fixing frame 34. At this time, the staff turns on the power of the motor 21, and the motor 21 drives the fixing block 23 and the stirring blades 24 on the side wall to rotate through the driving rod 22, and the mixing and stirring process is started. At this time, the stirring blades 24 will rotate counterclockwise, forcing the driving blades 33 to contact the external solution, presenting as shown Figure 4 In the state shown, water flows from Figure 4 When the solution flows downward from the top of the stirring blade 24, the driving blade 33 will generate a thrust to the left, and the driving blade 33 will drive the scraper 31 to move along the outer wall of the stirring blade 24 toward the fixed block 23 through the rotating plate 32. In this process, the scraper 31 will clean the outer wall of the stirring blade 24; in the process of the scraper 31 moving, the scraper 31 will drive the pressure rod 311 to contact the side wall of the fixed block 23, and the pressure rod 311 is blocked to force the pushing rods 310 at both ends to expand to both ends, and the pushing rod 310 drives the inclined surface block 38 to expand outward synchronously through the L-shaped rod 39, so that the inclined surface block 38 no longer restricts the arc surface block 36, and at this time the external solution continues to impact the driving blade 33, forcing the driving blade 33 to swing around the fixed rod 312 as the center, and at this time Figure 5The arc block 36 in the middle will follow the swing of the driving blade 33 and contact the inclined block 38 at the other end, and the arc surface of the arc block 36 will contact the inclined surface of the inclined block 38. Finally, the arc block 36 breaks through the restriction of the inclined block 38, so that the other inclined block 38 restricts the rotation of the driving blade 33. At this time, the direction of the driving blade 33 changes. When the external water flow contacts the driving blade 33, it will push the driving blade 33 to move outward, and the driving blade 33 drives the scraper 31 to move outward along the outer wall of the stirring blade 24 through the rotating plate 32, and the outer wall of the stirring blade 24 is cleaned twice. Through the application of the above-mentioned components, the stirring blade 24 can remove large pieces of sludge stuck to the outer wall of the stirring blade 24 by the back and forth sliding of the scraper 31 when stirring, so as to avoid the sludge being adsorbed on the outer wall of the stirring blade 24 and affecting the mixing efficiency of the equipment.

[0043] Taking advantage of the fact that the scraper 31 slides along the outer wall of the stirring blade 24, a control component 4 is provided on the inner wall of the device. When the scraper 31 moves outward, the support frame 45 drives the gear rod 43 to slide outward along the inner wall of the sliding frame 42 through the arc-shaped fixed rod 44. At this time, the gear rod 43 will drive the gear 41 to rotate. In this process, the number of revolutions of the gear 41 will indirectly control the outward extension length and speed of multiple gear rods 43, and indirectly control the outward extension length of multiple support frames 45 and the scraper 31. Through the application of the above-mentioned components, the device can control the specific position of the blade cleaning mechanism 3 on the stirring blade 24 and the sliding speed during the mixing and stirring process, so as to avoid changes in the position of each blade cleaning mechanism 3, which will cause the center of gravity of the rotation of the stirring blade 24 to shift, affecting the device. In order to improve the rotation efficiency of the equipment, the gear 41 is used to control the sliding of the multiple scrapers 31. During the rotation of the fixed block 23, the force of the multiple scrapers 31 sliding outward or inward is transmitted to the gear 41 through the corresponding gear rod 43, and the gear 41 will collect the force of the multiple scrapers 31 moving to generate self-rotation; if there are larger impurities in the solution at this time and they stick to the outer wall of one of the stirring blades 24, the corresponding scraper 31 will be blocked and unable to move. At this time, the gear 41 collects the force transmitted by the multiple gear rods 43 and acts on the position of the blocked gear rod 43, forcing the gear rod 43 to generate a larger thrust outward, forcing the corresponding scraper 31 to push outward, and remove the large impurities stuck to the outer wall of the stirring blade 24. Through the application of the above components, it is prevented that large impurities affect the cleaning effect of the equipment.

[0044] Taking advantage of the above-mentioned characteristic of the rotation of the driving blades 33, a cleaning component 5 is provided inside the equipment. When the driving blades 33 rotate, the distance between the rotating plate 32 and the fixed plate 51 will be reduced. In this process, the hydraulic cylinder 52 will be subjected to pressure and force the internal solution to be transmitted to the inside of the storage box 53 through the delivery pipe 57. The increase in the solution inside the storage box 53 forces multiple hydraulic telescopic rods 55 to expand to both ends. At this time, the hydraulic telescopic rods 55 drive the impurity scraper 56 to move outward along the outer wall of the driving blades 33, so that the impurity scraper 56 scratches and cleans the outer wall of the driving blades 33. Through the application of the above-mentioned components, impurities can be prevented from sticking to the outer wall of the driving blades 33 and affecting the swinging speed of the driving blades 33.

[0045] After completing the above process, the solution passes through Figure 1 The pipe F in the middle discharges to the outside.
