Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a coagulant dissolving mixer for wastewater treatment. Background Art

[0002] In wastewater treatment, the dissolution of coagulants directly impacts treatment efficiency and quality. Currently, commonly used coagulant dissolution methods suffer from slow and incomplete dissolution, preventing the coagulant from fully functioning. This not only wastes the agent but also compromises wastewater treatment effectiveness. Existing devices are inadequate in improving coagulant dissolution rates, necessitating a novel device to address this technical challenge.

[0003] A Chinese patent with authorization announcement number CN209952848U discloses a stirring reaction device for preparing an inorganic polymer coagulant suitable for low-temperature and low-turbidity water quality. The device mainly includes a tank body, a feed inlet, a liquid inlet and an exhaust port are arranged on the top of the tank body, and a stirring device is arranged in the tank body. The stirring device includes a stirring shaft, a stirring motor and stirring blades. The stirring motor is fixed above the tank body by a bracket. The stirring shaft is placed vertically in the tank body, one end is connected to the stirring motor, and the other end extends to the bottom of the tank body. The stirring blades are evenly connected to the stirring shaft. However, the above-mentioned device adds the coagulant all at once, which is not conducive to the rapid dissolution of the coagulant. In addition, its stirring structure is relatively simple, and the stirring efficiency needs to be improved. Summary of the Invention

[0004] The object of the present invention is to provide a coagulant dissolving and stirring machine for wastewater treatment, which has the effects of significantly improving the uniform distribution of materials in a tank body and increasing the solubility.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: it includes a tank body, the center of the tank body is rotatably connected to a stirring shaft, and it is characterized in that: a plurality of stirring mechanisms are arranged at intervals on the stirring shaft, the stirring mechanism includes a stirring drum, the outer wall of the stirring drum is evenly provided with a plurality of discharge holes, a push rod of a driving assembly passes through one side of the stirring drum, one end of the push rod located in the stirring drum is vertically fixed with a circular push plate, the other end of the push rod located outside the stirring drum is rotatably inserted with a short rod 1 vertically connected to the driving rod, the other end of the driving rod is vertically connected to a short rod 2, and the short rod 2 is vertically fixed to the circumferential end face of a gear. The gear 1 is meshed with the internal teeth of the inner wall surface of the annular gear plate 1, and the rotating shaft at the center of the gear 1 is limited and rotatably connected to the gear 1, and the other end thereof is vertically limited and rotatably connected to the circumferential end surface of the rotating circular plate, the annular gear plate 1 is fixed to the bottom surface of the annular plate 2, the rotating circular plate is rotatably connected to the inner wall of the annular plate 2, the rotating circular plate is coaxially connected to the planetary gear 2, the planetary gear 2 is externally meshed with the power gear fixed on the stirring shaft and the internal teeth of the inner wall surface of the annular gear plate 3 at the same time, the number of the planetary gears 2 is 2 and they are symmetrically distributed, and the upper end surface of the annular gear plate 3 is symmetrically and vertically fixed with support rods at equal intervals, and the support rods are fixed to the inner wall surface of the tank body.

[0006] By adopting the above technical solution, the agitator shaft rotates to drive the power gear to rotate. At this time, the planetary gear 2 between the power gear and the fixed annular gear plate 3 revolves around the power gear and rotates on its own. Since the planetary gear 2 and the rotating circular plate are coaxially connected, the rotating circular plate will be driven to rotate on the inner wall of the annular plate 2. Since the annular gear plate 1 is fixed on the annular plate 2, when the rotating circular plate rotates, the gear 1 connected to the circumferential end face of the rotating circular plate is driven to rotate. Since the gear 1 is externally meshed with the annular gear plate 1 at this time, the gear 1 rotates on its own at the same time. Finally, the reciprocating push of the push rod in the horizontal direction is achieved through the rotation and revolution of the gear 1. The circular push plate at the end of the push rod reciprocates in the mixing drum, pushing the coagulant in the mixing drum out of the discharge hole. The circular push plate discharges the material continuously during the horizontal reciprocating motion, and since the planetary gear 2 revolves around the power gear, it drives the entire drive assembly and the mixing drum to revolve around the power gear, i.e., the mixing shaft. When the mixing drum rotates around the mixing shaft, the material is discharged while the material just discharged is stirred in time. The two are carried out at the same time, which significantly improves the uniform distribution of the material in the tank and increases the solubility, avoiding the situation where all the material is thrown into the tank at once, making it difficult to break up and dissolve the material.

[0007] The present invention is further configured as follows: a gear three is fixed to a side surface of the mixing drum close to the inner wall of the tank body, the gear three is externally meshed with an annular rack on the inner wall of the tank body, and the other side of the mixing drum away from the tank body is limitedly rotated and connected to a support plate one, the support plate one is L-shaped and is vertically fixed to the outer circumferential surface of the annular plate two, and the push rod passes through the vertical plate of the support plate.

[0008] By adopting the above technical solution, gear three can mesh with the annular rack externally. Since the annular rack is fixed, gear three rotates while rotating with the mixing drum around the drive shaft, and finally the mixing drum also rotates. The rotation of the mixing drum itself will also throw the material inside the mixing drum out from the discharge hole under the action of centrifugal force. Combined with the pushing force of the circular push plate, the material is accelerated to be ejected from the discharge hole, ensuring that the material is discharged from time to time and dissolved in the tank body, thereby improving the dissolution efficiency of the coagulant.

[0009] The present invention is further configured as follows: the annular rack is fixed obliquely to the inner wall surface of the tank body.

[0010] The present invention is further configured as follows: the outer side surface of the rotating shaft at the center of the planetary gear 2 is provided with an axial long strip spline, and the long strip spline cooperates with the planetary gear 2 and the rotating circular plate key at the same time; the planetary gear 2 is vertically slidably connected to the long strip spline, and a slide is fixed on the other side of the annular plate 2 relative to the support plate 1, and the slide is slidably connected to the slide rail, and the slide rail is vertically fixed to the bottom surface of the supporting horizontal plate, the stirring shaft and the rotating shaft at the center of the planetary gear 2 both pass through the supporting horizontal plate, the supporting horizontal plate is fixed to the bottom surface of the gear 1, and the planetary gear 2 rotates relative to the supporting horizontal plate.

[0011] By adopting the above technical solution, since the annular rack is set at an angle, the gear three that is meshed with the outside of the annular rack realizes movement in the vertical direction in contact with the annular rack. When the gear three moves in the vertical direction, it drives the mixing drum and the entire driving mechanism to move in the vertical direction. Since an axial long spline is provided on the outer side of the rotating shaft connected between the planetary gear two and the rotating circular plate, it is ensured that when the rotating circular plate slides up and down on the rotating shaft of the long spline, it will also be driven to rotate by the planetary gear two, and the two will not cause interference. Finally, when the mixing drum rotates around the mixing shaft, it rotates in the vertical direction at the same time, so that the tank body can be stirred and dissolved within a certain height range. By arranging 3 groups of stirring structures in the vertical direction, it can be ensured that the wastewater within the tank body height corresponding to each group of stirring mechanisms can be stirred to the maximum extent, and the coagulant can be dissolved to the maximum extent, thereby ensuring the efficient treatment of subsequent wastewater. In addition, the setting of the slide plate ensures that the entire driving mechanism and the mixing drum can be stably lifted and lowered in the vertical direction.

[0012] The present invention is further configured as follows: the circumferential side of the mixing drum is symmetrically connected to two mixing rods for vertical rotation, the end of the mixing rod in contact with the mixing drum is fixed with a first bevel gear, the first bevel gear is externally meshed with the second bevel gear, the second bevel gear is fixed to one end of the rotating shaft, and the other end of the rotating shaft is fixed with gear four, the gear four is externally meshed with gear five, the gear five is fixed on a support plate one, and the gear five is sleeved on the outside of the mixing drum.

[0013] The present invention is further configured as follows: the number of the stirring rods is symmetrically distributed on opposite sides of the stirring drum, and a plurality of stirring rods are arranged on the stirring rods at intervals.

[0014] By adopting the above technical solution, since gear five is fixed on support plate one, and the mixing drum rotates relative to support plate one, when the mixing drum rotates on support plate one, gear four is driven to rotate on gear five, and gear four is coaxially connected to the second bevel gear. At this time, the second bevel gear rotates, and further, the first bevel gear meshing with the outside of the second bevel gear rotates, and finally drives the stirring rod to rotate. At this time, the rotation direction of the stirring rod is perpendicular to the rotation direction of the mixing drum. Therefore, the stirring rod and the stirring rod on the stirring rod can further stir the wastewater in the tank body, avoiding the wastewater around the mixing drum from being in one flow direction all the time, resulting in a slowdown in dissolution efficiency. The setting of the stirring rod can generate flows of different directions and intensities, so that the coagulant can be fully stirred and mixed in the vertical direction, increasing the contact opportunity between the coagulant and the wastewater, thereby improving its solubility.

[0015] The present invention is further configured as follows: a feeding port 1 is provided on the end face of the mixing drum close to the inner wall of the tank body; a hole plug 1 is threadedly connected to the feeding port 1; and an operating ring 1 is fixed to the hole plug 1.

[0016] The present invention is further configured as follows: a second feeding port is provided on the outer wall of the tank body at a height corresponding to each of the stirring mechanisms; a second hole plug is threadedly connected to the second feeding port; a second operating ring is fixed to the second hole plug; the second feeding port is located at the same height as the first feeding port in each of the stirring mechanisms; the diameter of the second feeding port is larger than the diameter of the first feeding port; and the outer shell of the tank body at the second feeding port is made of a transparent material.

[0017] By adopting the above technical solution, when it is necessary to add coagulant into the mixing drum, the feeding port 1 is aligned with the feeding port 2, and accurate observation can be made through the transparent material of the tank body. After unscrewing the hole plug 2, the hole plug 1 is unscrewed, and finally the coagulant is added into the mixing drum. By setting the size of the mixing drum, it can be ensured that no re-addition is required when treating wastewater once.

[0018] The present invention is further configured as follows: a driving motor is fixed to the top surface of the tank body, and the driving motor is coaxially fixedly connected to the end of the stirring shaft through a coupling.

[0019] The present invention is further configured as follows: a feed pipe is provided on the top surface of the tank body, and a discharge pipe is provided on the bottom surface of the tank body.

[0020] By adopting the above technical solution, the feed pipe is used to input wastewater, and the wastewater is discharged from the discharge pipe after treatment.

[0021] The beneficial effects of the present invention are:

[0022] 1. The rotation of the agitator shaft drives the power gear to rotate. The planetary gear 2 between the power gear and the fixed annular gear plate 3 revolves around the power gear and rotates on its own. Since the planetary gear 2 is coaxially connected to the rotating circular plate, it will drive the rotating circular plate to rotate on the inner wall of the annular plate 2. Since the annular gear plate 1 is fixed on the annular plate 2, when the rotating circular plate rotates, the gear 1 connected to the circumferential end face of the rotating circular plate is driven to rotate. Since the gear 1 is externally meshed with the annular gear plate 1 at this time, the gear 1 rotates on its own at the same time. Finally, the push rod is pushed back and forth in the horizontal direction through the rotation and revolution of the gear 1, and the end of the push rod is pushed back and forth. The circular push plate reciprocates in the mixing drum, pushing the coagulant in the mixing drum out of the discharge hole. The circular push plate continuously discharges the material during its horizontal reciprocating motion, and since the planetary gear 2 revolves around the power gear, it drives the entire drive assembly and the mixing drum to revolve around the power gear, i.e., the mixing shaft. When the mixing drum rotates around the mixing shaft, the material is discharged while the material just discharged is stirred in time. The two are carried out simultaneously, which significantly improves the uniform distribution of the material in the tank and increases the solubility, avoiding the situation where all the material is thrown into the tank at once, making it difficult to break up and dissolve the material.

[0023] 2. The annular rack is tilted, so the gear three that is meshed with the annular rack outside realizes movement in the vertical direction in contact with the annular rack. When the gear three moves in the vertical direction, it drives the mixing drum and the entire driving mechanism to move in the vertical direction. Since an axial long spline is provided on the outer side of the rotating shaft connected between the planetary gear two and the rotating circular plate, it is ensured that when the rotating circular plate slides up and down on the rotating shaft of the long spline, it will also be driven to rotate by the planetary gear two, and the two will not cause interference. Finally, when the mixing drum rotates around the mixing shaft, it rotates in the vertical direction at the same time, so that the tank body can be stirred and dissolved within a certain height range. By arranging 3 groups of stirring structures in the vertical direction, it can be ensured that the wastewater within the tank body height corresponding to each group of stirring mechanisms can be stirred to the maximum extent, and the coagulant can be maximized. Dissolution, thereby ensuring efficient subsequent wastewater treatment, is ensured. In addition, the setting of the slide plate ensures that the entire driving mechanism and the mixing drum can be stably lifted and lowered in the vertical direction.

[0024] 3. Gear five is fixed on support plate one, and the mixing drum rotates relative to support plate one, so when the mixing drum rotates on support plate one, it drives gear four to rotate on gear five. Gear four is coaxially connected to the second bevel gear. At this time, the second bevel gear rotates, and further, the first bevel gear meshing with the outside of the second bevel gear rotates, and finally drives the stirring rod to rotate. At this time, the rotation direction of the stirring rod is perpendicular to the rotation direction of the mixing drum. Therefore, the stirring rod and the stirring rod on the stirring rod can further stir the wastewater in the tank body, avoiding the wastewater around the mixing drum from being in one flow direction all the time, resulting in a change in dissolution efficiency. The setting of the stirring rod can generate flows of different directions and intensities, so that the coagulant can be fully stirred and mixed in the vertical direction, increasing the contact opportunity between the coagulant and the wastewater, thereby improving its solubility.

[0025] 4. The entire device adopts a single power source of the driving motor and utilizes the interaction between various structures to achieve efficient stirring and dissolving of the coagulant, thereby improving the utilization efficiency of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The technical solutions of the present invention will be described clearly and completely below with reference to specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0035] Embodiment, a coagulant dissolving mixer for wastewater treatment, such as Figure 1-6As shown, it includes a tank body 1, a stirring shaft 2 is rotatably connected to the center of the tank body 1, a number of stirring mechanisms are arranged at intervals on the stirring shaft 2, the stirring mechanism includes a stirring drum 3, a number of discharge holes 4 are evenly arranged on the outer wall of the stirring drum 3, a push rod 5 of a driving assembly is passed through one side of the stirring drum 3, a circular push plate 6 is vertically fixed to one end of the push rod 5 located in the stirring drum 3, a short rod 7 vertically connected to the driving rod 8 is rotatably inserted at the other end of the push rod 5 located outside the stirring drum 3, a short rod 2 9 vertically connected to the other end of the driving rod 8, the short rod 2 9 is vertically fixed to the circumferential end face of the gear 10, the gear 10 is meshed with the internal meshing teeth of the inner wall surface of the annular gear plate 11, and the gear 10 The central rotating shaft is limited in rotation and connected to the gear 10, and the other end thereof is vertically limited in rotation and connected to the circumferential end surface of the rotating circular plate 12. The annular gear plate 11 is fixed to the bottom surface of the annular plate 2 13. The rotating circular plate 12 is rotatably connected to the inner wall of the annular plate 2 13. The rotating circular plate 12 is coaxially connected to the planetary gear 2 14. The planetary gear 2 14 is simultaneously externally meshed with the power gear 15 fixed on the stirring shaft 2 and the inner teeth of the inner wall of the annular gear plate 3 16. The number of planetary gears 2 14 is 2 and symmetrically distributed. The upper end surface of the annular gear plate 3 16 is symmetrically and vertically fixed with support rods 17 at equal intervals. The support rods 17 are fixed to the inner wall of the tank body 1, and the stirring shaft 2 rotates to drive the power gear 15 rotates, and the planetary gear 2 14 between the power gear 15 and the fixed annular gear plate 3 16 revolves around the power gear 15 and rotates on its own. Since the planetary gear 2 14 is coaxially connected to the rotating circular plate 12, it drives the rotating circular plate 12 to rotate on the inner wall of the annular plate 2 13. Since the annular gear plate 11 is fixed on the annular plate 2 13, when the rotating circular plate 12 rotates, the gear 10 connected to the circumferential end face of the rotating circular plate 12 is driven to rotate. Since the gear 10 is meshed with the outer surface of the annular gear plate 11 at this time, the gear 10 rotates on its own at the same time. Finally, the push rod 5 is pushed back and forth in the horizontal direction by the rotation and revolution of the gear 10, and the push rod The circular push plate 6 at the end of 5 reciprocates in the mixing drum 3 to push the coagulant in the mixing drum 3 out of the discharge hole 4. When the circular push plate 6 reciprocates horizontally, the material is discharged continuously. Since the planetary gear 14 revolves around the power gear 15, it drives the entire drive assembly and the mixing drum 3 to revolve around the power gear 15, that is, the mixing shaft 2. When the mixing drum 3 rotates around the mixing shaft 2, the material is discharged while the material just discharged is stirred in time. The two are carried out simultaneously, which significantly improves the uniform distribution of the material in the tank body 1 and increases the solubility, and avoids the situation where the material is difficult to be dispersed and dissolved due to all the material being thrown into the tank body 1 at once.

[0036] like Figure 1-6As shown, a gear three 18 is fixed to one side of the mixing drum 3 close to the inner wall of the tank body 1, and the gear three 18 is externally meshed with the annular rack 19 on the inner wall of the tank body 1. The other side of the mixing drum 3 away from the tank body 1 is limited and rotatably connected to the support plate 1 20. The support plate 1 20 is L-shaped and vertically fixed to the outer side of the circumference of the annular plate 2 13. The push rod 5 passes through the vertical plate of the support plate. The gear three 18 can be externally meshed with the annular rack 19. Since the annular rack 19 is fixed, the gear three 18 rotates while rotating with the mixing drum 3 around the drive shaft, and finally the mixing drum 3 also rotates. The rotation of the mixing drum 3 itself will also throw the material inside the mixing drum 3 out of the discharge hole 4 under the action of centrifugal force, and the driving force of the circular push plate 6 will accelerate the material to be ejected from the discharge hole 4, ensuring that the material is discharged from time to time and dissolved in the tank body 1, thereby improving the dissolution efficiency of the coagulant.

[0037] like Figure 1-6 As shown, the annular rack 19 is tilted and fixed to the inner wall of the tank body 1, and the outer side surface of the rotating shaft of the center of the planetary gear 2 14 is provided with an axial long strip spline 21, and the long strip spline 21 cooperates with the planetary gear 2 14 and the rotating circular plate 12 at the same time. The planetary gear 2 14 is vertically slidably connected to the long strip spline 21, and a slide plate 22 is fixed on the other side of the annular plate 2 13 relative to the support plate 1 20. The slide plate 22 is slidably connected to the slide rail 23, and the slide rail 23 is vertically fixed to the bottom surface of the support cross plate 24. The rotating shaft of the center of the stirring shaft 2 and the planetary gear 2 14 both penetrates the support cross plate 24, and the support cross plate 24 is fixed to the bottom surface of the gear 1 10, and the planetary gear 2 14 rotates relative to the support cross plate 24. Since the annular rack 19 is tilted, the gear 3 18 meshing with the outside of the annular rack 19 realizes movement in the vertical direction in contact with the annular rack 19. When the gear 3 1 When 8 moves in the vertical direction, it drives the mixing drum 3 and the entire driving mechanism to move in the vertical direction. Since an axial long strip spline 21 is provided on the outer side surface of the rotating shaft connected between the planetary gear 2 14 and the rotating circular plate 12, it is ensured that when the rotating circular plate 12 slides up and down on the rotating shaft of the long strip spline 21, it will also be driven to rotate by the planetary gear 2 14, and the two will not cause interference. Finally, when the mixing drum 3 rotates around the stirring shaft 2, it rotates in the vertical direction at the same time, so that the tank body 1 can be stirred and dissolved within a certain height range. By arranging 3 groups of stirring structures in the vertical direction, it can be ensured that the wastewater within the height of the tank body 1 corresponding to each group of stirring mechanisms can be stirred to the maximum extent, and the coagulant can be dissolved to the maximum extent, thereby ensuring the efficient treatment of subsequent wastewater. In addition, the setting of the slide plate 22 ensures that the entire driving mechanism and the mixing drum 3 can be stably lifted and lowered in the vertical direction.

[0038] like Figure 1-6As shown, the circumferential side of the mixing drum 3 is symmetrically connected to two stirring rods 25 for vertical rotation. The end of the stirring rod 25 in contact with the mixing drum 3 is fixed with a first bevel gear 26, and the first bevel gear 26 is externally meshed with the second bevel gear 27. The second bevel gear 27 is fixed to one end of the rotating shaft 28, and the other end of the rotating shaft 28 is fixed with a gear four 29, which is externally meshed with the gear five 30. The gear five 30 is fixed on the support plate 1 20, and the gear five 30 is sleeved on the outside of the mixing drum 3. The number of stirring rods 25 is symmetrically distributed on the opposite sides of the mixing drum 3. A number of stirring rods 31 are arranged at intervals on the stirring rod 25. Since the gear five 30 is fixed on the support plate 1 20, and the mixing drum 3 rotates relative to the support plate 1 20, when the mixing drum 3 rotates on the support plate 1 20 , driving gear four 29 to rotate on gear five 30, gear four 29 is coaxially connected to the second bevel gear 27, at this time the second bevel gear 27 rotates, further, the first bevel gear 26 meshing with the outside of the second bevel gear 27 rotates, and finally drives the stirring rod 25 to rotate. At this time, the rotation direction of the stirring rod 25 is perpendicular to the rotation direction of the mixing drum 3. Therefore, the stirring rod 25 and the stirring rod 31 on the stirring rod 25 can further stir the wastewater in the tank body 1, avoiding the wastewater around the mixing drum 3 being in one flow direction all the time and causing the dissolution efficiency to change. The setting of the stirring rod 25 can generate flows of different directions and intensities, so that the coagulant can be fully stirred and mixed in the vertical direction, increasing the contact opportunity between the coagulant and the wastewater, thereby improving its solubility.

[0039] like Figure 1-6 As shown, a feeding port 1 is provided on the end face of the mixing drum 3 near the inner wall of the tank body 1, and a hole plug 1 32 is threadedly connected to the feeding port 1, and an operating ring 1 33 is fixed on the hole plug 1 32. A feeding port 2 is provided on the outer wall of the tank body 1 at the corresponding height of each stirring mechanism, and a hole plug 2 34 is threadedly connected to the feeding port 2, and an operating ring 2 35 is fixed on the hole plug 2 34. The feeding port 2 and the feeding port 1 in each stirring mechanism are located at the same height, and the diameter of the feeding port 2 is larger than the diameter of the feeding port 1. The outer shell of the tank body 1 at the feeding port 2 is made of transparent material. When it is necessary to add coagulant into the mixing drum 3, the feeding port 1 is aligned with the feeding port 2, and accurate observation can be carried out through the transparent material of the tank body 1. After unscrewing the hole plug 2 34, the hole plug 1 32 is unscrewed, and finally the coagulant is added into the mixing drum 3. By setting the size of the mixing drum 3, it can be ensured that no re-addition is required when treating wastewater once.

[0040] like Figure 1-6 As shown, a drive motor 36 is fixed on the top surface of the tank body 1, and the drive motor 36 is coaxially fixedly connected to the end of the stirring shaft 2 through a coupling. A feed pipe 37 is provided on the top surface of the tank body 1, and a discharge pipe 38 is provided on the bottom surface of the tank body 1. The feed pipe 37 is used to input wastewater, and the wastewater is discharged from the discharge pipe 38 after treatment.

[0041] The working principle of a coagulant dissolving mixer for wastewater treatment:

[0042] When it is necessary to add coagulant into the mixing drum 3, the feeding port 1 is aligned with the feeding port 2, and accurate observation can be made through the transparent material of the tank body 1. After unscrewing the hole plug 2 34, the hole plug 1 32 is unscrewed, and finally the coagulant is added into the mixing drum 3. By setting the size of the mixing drum 3, it can be ensured that no re-addition is required when treating wastewater once.

[0043] Wastewater is added from the feed pipe 37, and then the drive motor 36 is started. The stirring shaft 2 rotates to drive the power gear 15 to rotate. The planetary gear 2 14 between the power gear 15 and the fixed annular gear plate 3 16 revolves around the power gear 15 and rotates on its own axis. Since the planetary gear 2 14 and the rotating circular plate 12 are coaxially connected, the rotating circular plate 12 is driven to rotate on the inner wall of the annular plate 2 13. Since the annular gear plate 1 11 is fixed on the annular plate 2 13, when the rotating circular plate 12 rotates, the gear 10 connected to the circumferential end face of the rotating circular plate 12 is driven to rotate. Since the gear 10 is meshed with the outer surface of the annular gear plate 11 at this time, the gear 10 rotates on its own axis at the same time. Finally, the rotation and revolution of the gear 10 are realized. Now, the push rod 5 is pushed back and forth in the horizontal direction, and the circular push plate 6 at the end of the push rod 5 reciprocates in the mixing drum 3, pushing the coagulant in the mixing drum 3 out of the discharge hole 4. When the circular push plate 6 reciprocates horizontally, the material is discharged continuously, and because the planetary gear 2 14 revolves around the power gear 15, it will drive the entire drive assembly and the mixing drum 3 to revolve around the power gear 15, that is, the mixing shaft 2, so that when the mixing drum 3 rotates around the mixing shaft 2, the material is discharged while the material just discharged is stirred in time. The two are carried out at the same time, which significantly improves the uniform distribution of the material in the tank body 1 and increases the solubility, and avoids the situation where the material is difficult to break up and dissolve due to all the material being thrown into the tank body 1 at once.
