Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment experimental device and process for ice cream production. Background Technology

[0002] Ice cream is a seasonal product, and production increases in the summer, which in turn leads to a surge in factory wastewater. This food factory wastewater mainly contains milk fat, lactose, milk protein, palm oil, coconut oil, chocolate, cocoa powder, maltose, white sugar, and large particulate floating debris.

[0003] Common wastewater treatment methods for ice cream factories are mainly divided into three categories: physical treatment, chemical treatment, and biological treatment. Physical treatment separates and recovers insoluble suspended pollutants from ice cream production wastewater through physical processes. The conventional operation involves adding flocculants and thoroughly mixing the wastewater with the flocculants to form flocs that are easy to settle or filter, thereby purifying the water. For example, CN220283755U discloses a flocculant mixing device for tailings wastewater treatment, in which flocculants are directly added and then stirred using conventional fixed agitators; similarly, CN209081511U discloses a flocculant mixing device for wastewater treatment, in which flocculants are directly added and then stirred using conventional fixed agitators. Therefore, currently, when mixing ice cream factory wastewater with flocculants, the common practice is to directly add flocculants and then stir using conventional fixed agitators. However, this method cannot quickly and thoroughly mix the flocculants with the wastewater, affecting treatment efficiency. Therefore, it is necessary to design a wastewater treatment experimental device and process for ice cream production to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a wastewater treatment experimental device and process for ice cream production to solve the above-mentioned problems.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a wastewater treatment experimental device for ice cream production, comprising:

[0006] A wastewater treatment tank, wherein the wastewater treatment tank is provided with a mixing mechanism, an adding mechanism and a mixing enhancement mechanism;

[0007] The mixing mechanism includes a rotating shaft, a hollow seat, a piston cylinder one, a pipe, a piston cylinder two, a piston rod one, a piston rod two, a stirring component one, and a stirring component two;

The connector is fixedly mounted between the piston rod and the branch pipe. The piston is slidably and sealingly mounted inside the flocculant storage box. The bottom of the vertical rod is fixedly connected to the piston. The screw is threadedly connected to the vertical rod. The block is fixedly mounted on the outside of the vertical rod. The vertical rod is slidably mounted on the rotating shaft.

[0011] By adopting the above technical solution, flocculants can be added evenly, thereby improving the mixing efficiency of wastewater and flocculants.

[0012] A further configuration of the present invention is as follows: the mixing and enhancing mechanism includes an auxiliary component one, an auxiliary component two, a sleeve disc, and a mating joint. The auxiliary component one is fixedly connected to the auxiliary component two and the mating joint. The sleeve disc is fixedly sleeved on the outside of the vertical rod. The vertical rod is rotatably mounted on the auxiliary component two. The sleeve disc is in contact with the auxiliary component two. The auxiliary component one is vertically slidably mounted on the sewage treatment tank.

[0013] A further feature of the present invention is that a top frame is fixedly installed on the top of the sewage treatment tank, a control panel is fixedly installed on the top of the top frame, an auxiliary component 2 is slidably sleeved on the outside of the top frame, and the top of the screw is fixedly connected to the top frame.

[0014] By adopting the above technical solution, the auxiliary component two can move stably in the vertical direction.

[0015] A further feature of the present invention is that: a door is provided on the back of the sewage treatment tank, an ice cream wastewater addition pipe is fixedly provided on the top of the sewage treatment tank, a support frame is fixedly provided on the bottom of the sewage treatment tank, a drain pipe is fixedly provided on the bottom of the sewage treatment tank, and a valve is installed on the drain pipe.

[0016] By adopting the above technical solution, it is convenient to discharge the treated wastewater.

[0017] A further feature of the present invention is that the crossbar is laterally slidably sealed on piston cylinder one and hollow seat, and a sealing bottom cover is fixedly connected to the bottom of the hollow seat by fixing screws. Hydraulic oil is stored in piston cylinder one, piston cylinder two and pipeline.

[0018] A further feature of the present invention is that the top of the rotating shaft has a vertical hole and a square hole, the vertical rod is slidably installed in the vertical hole, and the square block is slidably installed in the square hole.

[0019] A further feature of the present invention is that a feeding pipe is fixedly installed on the top of the flocculant storage box, and a sealing plug is installed on the feeding pipe.

[0020] A wastewater treatment test process for ice cream production, applicable to the wastewater treatment test equipment for ice cream production as described in any of the above, includes at least the following steps:

[0021] Step 1: Add ice cream wastewater to the wastewater treatment tank, add flocculant to the flocculant storage box, start the servo motor, and drive the shaft to rotate through gear 1 and gear 2. This causes the hollow seat, piston cylinder 1, pipe, piston cylinder 2, piston rod 1, piston rod 2, and agitator 1 and agitator 2 to rotate synchronously. During the rotation of the extrusion ball, the mating joint will intermittently extrude the extrusion ball. During extrusion, piston rod 1 will move, causing the crossbar to compress the spring. Piston rod 1 will also drive piston rod 2 to move through the flowing hydraulic oil. The movement directions of piston rod 1 and piston rod 2 are opposite. During the separation of the extrusion ball from the mating joint, the spring will reset, allowing piston rod 1 and piston rod 2 to reset. This causes agitator 1 and agitator 2 to move laterally in opposite directions, which can quickly mix the flocculant with the ice cream wastewater.

[0022] Step Two: During the mixing process, the flocculant storage box, main pipe, hose, branch pipe, addition head, connector, and vertical rod rotate synchronously with the shaft. Since the screw and vertical rod are threadedly connected, the vertical rod will move upward when it rotates. The vertical rod drives the piston to move upward, and the piston lifts the flocculant in the flocculant storage box upward, so that the flocculant passes through the main pipe, hose, and branch pipe and is discharged from the addition head. In addition, the piston rod drives the branch pipe to move horizontally back and forth through the connector, and the branch pipe rotates continuously. In this way, the flocculant is evenly added into the wastewater treatment tank from the addition head. The addition method is more uniform and can quickly mix the flocculant with the ice cream wastewater.

[0023] Step 3: As the vertical rod rotates and moves vertically, the sleeve plate will drive the auxiliary component 2 to move vertically in sync. The auxiliary component 2 will drive the auxiliary component 1 to move, which will cause the mating joint to move slowly upward. As the mating joint moves slowly upward, the lateral obstruction distance of the extrusion ball will increase, which will increase the lateral reciprocating frequency of piston rod 1 and piston rod 2, further improving the efficiency of mixing flocculant with ice cream wastewater.

[0024] The beneficial effects of this invention are:

[0025] 1. This invention utilizes a mixing mechanism with a combined motion pattern of rotating and reciprocating lateral movement of the stirring components to significantly enhance the turbulence of wastewater. Compared to traditional single stirring methods, this effectively avoids the problem of localized accumulation of flocculants, promotes rapid and full contact between the flocculants and ice cream wastewater, and significantly improves mixing efficiency and reaction rate. At the same time, the linkage design of hydraulic transmission and spring reset enables the two sets of stirring components to move synchronously in opposite directions, further enhancing the mixing effect and accelerating the formation of flocs.

[0026] 2. This invention, through its specially designed addition mechanism, utilizes the synergistic effect of the rotating shaft and the screw thread transmission to achieve uniform and quantitative addition of flocculant. Combined with the synchronous rotation and reciprocating lateral movement of the branch pipes along with the stirring components, the flocculant is evenly sprayed from multiple addition heads throughout the wastewater, avoiding the problem of excessively high local concentrations caused by traditional direct addition. The entire addition process is synchronized with the mixing process, allowing the flocculant to immediately participate in the mixing reaction upon addition, significantly shortening the mixing cycle and improving the flocculation treatment effect.

[0027] 3. The present invention achieves a dynamic, stepwise increase in mixing intensity through a mixing enhancement mechanism. As the test progresses, the contact position between the abutment and the extrusion ball gradually changes as the vertical rod moves upward, increasing the reciprocating stroke of the stirring component and continuously enhancing the mixing intensity. This adapts to the mixing requirements of different stages of wastewater flocculation reaction and significantly improves the mixing efficiency of ice cream wastewater. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this invention can be understood through the specific circumstances.

[0048] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0049] First Embodiment

[0050] See Figures 1-6In a first embodiment of the present invention, a wastewater treatment experimental device for ice cream production includes:

[0051] Wastewater treatment tank 1 is equipped with a mixing mechanism 2, an adding mechanism 3 and a mixing enhancement mechanism 4.

[0052] The mixing mechanism 2 includes a rotating shaft 201, a hollow seat 205, a piston cylinder 1 206, a pipe 207, a piston cylinder 208, a piston rod 1 209, a piston rod 210, a stirring component 1 211, and a stirring component 212;

[0053] The rotating shaft 201 is rotatably mounted on the sewage treatment tank 1. The hollow seat 205 is fixedly mounted on the bottom of the rotating shaft 201. Piston cylinder 1 206 and piston cylinder 208 are fixedly connected to the hollow seat 205 and the rotating shaft 201, respectively. Pipe 207 is fixedly mounted on piston cylinder 1 206 and piston cylinder 208. Piston rod 1 209 and piston rod 210 are slidably and sealingly mounted on piston cylinder 1 206 and piston cylinder 208, respectively. It should be noted that piston rod 1 209 and piston rod 210 are slidably and sealingly mounted by means of sealing gaskets. The sealing gaskets are made of high wear-resistant material, such as nitrile rubber.

[0054] The agitator 1 211 and agitator 212 are fixedly connected to piston rod 1 209 and piston rod 210, respectively.

[0055] Furthermore, the mixing mechanism 2 also includes a servo motor 202, gear one 203, gear two 204, guide frame 213, extrusion ball 214, crossbar 215, inner support 216, and spring 217. The servo motor 202 is fixedly installed on the top of the sewage treatment tank 1, and the output end of the servo motor 202 is fixedly connected to gear one 203. Gear two 204 is fixedly sleeved on the outside of the rotating shaft 201, and gear one 203 meshes with gear two 204. The guide frame 213 is fixedly installed on the outside of the pipe 207. Agitator one 211 and agitator two 212 are both slidably sleeved on the outside of the guide frame 213. Extrusion ball 214 is fixedly connected to piston rod one 209, and the end of crossbar 215 is fixedly connected to piston rod one 209. The inner support 216 is fixedly installed on the top inner wall of the hollow seat 205. The spring 217 is fixedly installed between the crossbar 215 and the inner support 216. It should be noted that the spring 217 is made of alloy. Spring steel helical compression springs have strong fatigue resistance and high strength, meeting the requirements of long-term use. The speed of servo motor 202 is set to 60-100 r / min. At this speed, the centrifugal force of the extruded ball 214 is calculated using the centrifugal force calculation formula. The preload of spring 217 must be greater than the centrifugal force of extruded ball 214 at the maximum speed. It can be set that the centrifugal force at this speed is ≤ 1 / 3 of the preload of spring 217. At this time, the restoring force of spring 217 cannot be offset, so it will not interfere with the contact between extruded ball 214 and mating joint 404 and the reciprocating movement of piston rod. That is, the final effect is that extruded ball 214 and piston rod are not affected by centrifugal force during rotation. Therefore, through the set mating joint 404, when extruded ball 214 contacts mating joint 404, the action of spring 217 will cause extruded ball 214 and piston rod to reciprocate.

[0056] Furthermore, a door 8 is provided on the back of the sewage treatment tank 1, an ice cream wastewater addition pipe 7 is fixedly installed on the top of the sewage treatment tank 1, a support frame 9 is fixedly installed on the bottom of the sewage treatment tank 1, and a drain pipe is fixedly installed on the bottom of the sewage treatment tank 1 with a valve installed on it. It should be noted that the door 8 is rotatably installed on the back of the sewage treatment tank 1. The door 8 is made of transparent material and is fixed to the sewage treatment tank 1 by a lock. A transparent observation plate is also provided on the back of the sewage treatment tank 1. The ice cream wastewater addition pipe 7 is connected to an external pump and flow valve for quantitative addition of ice cream wastewater.

[0057] Furthermore, the crossbar 215 is laterally sliding and sealed on the piston cylinder 206 and the hollow seat 205. The bottom of the hollow seat 205 is fixedly connected to a sealing bottom cover by fixing screws. Hydraulic oil is stored in the piston cylinder 206, piston cylinder 208 and pipe 207. It should be noted that a sealing gasket is fixedly embedded on the outside of the crossbar 215 to ensure the sealing of the connection between the crossbar 215 and the piston cylinder 206 and the hollow seat 205. When the piston rod 209 moves to the right, the piston rod 210 can move to the left.

[0058] In this embodiment:

[0059] Wastewater from ice cream production is quantitatively injected into wastewater treatment tank 1 through ice cream wastewater addition pipe 7. The feed pipe seal of flocculant storage box 301 is opened, the required flocculant for the experiment is added, and then the seal is closed again. Servo motor 202 is started, and through the meshing transmission of gear 1 203 and gear 2 204, the rotating shaft 201 is driven to rotate, which in turn drives the hollow seat 205, piston cylinder 1 206, piston cylinder 2 208, and two sets of stirring components to rotate synchronously, initially agitating the wastewater in the tank. The rotating shaft 201 drives the extrusion ball 214 to rotate synchronously with the stirring mechanism. During the rotation, the extrusion ball 214 will intermittently contact the mating joint 404. When in contact, the mating joint 404 engages with the extrusion ball 214. The lateral compression creates a force that pushes piston rod 209 to move, causing crossbar 215 to compress spring 217. Hydraulic oil in piston cylinder 206 is compressed by piston rod 209 and flows through pipe 207 into piston cylinder 208, pushing piston rod 210 to move in the opposite direction. This achieves reverse lateral movement of agitator 211 and agitator 212. When the compression ball 214 separates from the mating joint 404, spring 217 elastically resets, pulling piston rod 209 back. The hydraulic oil flows back, causing piston rod 210 to reset, and the two agitators return to their reverse positions. The agitators complete reciprocating lateral movement while rotating, significantly increasing the turbulence of the wastewater and preventing uneven mixing in certain areas.

[0060] Second Embodiment

[0061] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0062] Please refer to the following: Figures 7-11In this embodiment, a wastewater treatment test device for ice cream production is provided. The addition mechanism 3 includes a flocculant storage box 301, a main pipe 302, a hose 303, a branch pipe 304, an addition head 305, a connector 306, a piston 307, a vertical rod 308, a screw 309, and a block 310. The flocculant storage box 301 is fixedly installed on the rotating shaft 201, the main pipe 302 is fixedly installed on the flocculant storage box 301, the hose 303 is fixedly installed between the branch pipe 304 and the main pipe 302, and the addition head 305... 5. Fixedly installed on branch pipe 304, connector 306 is fixedly installed between piston rod 210 and branch pipe 304, piston 307 is slidably sealed inside flocculant storage box 301. It should be noted that piston 307 also achieves sealing when sliding through sealing gasket. The flocculant is in the upper part of piston 307. When piston 307 moves upward, it can push flocculant to move. In addition, multiple air holes are opened at the bottom of flocculant storage box 301 to ensure that piston 307 can move vertically.

[0063] The bottom of the vertical rod 308 is fixedly connected to the piston 307, the screw 309 is threadedly connected to the vertical rod 308, the block 310 is fixedly installed on the outside of the vertical rod 308, and the vertical rod 308 is slidably installed on the rotating shaft 201.

[0064] Furthermore, the top of the rotating shaft 201 is provided with a vertical hole 311 and a square hole 312. The vertical rod 308 is slidably installed in the vertical hole 311, and the square block 310 is slidably installed in the square hole 312. It should be noted that through the sliding cooperation between the square block 310 and the square hole 312, the vertical rod 308 can rotate synchronously with the rotating shaft 201 and move up and down.

[0065] Furthermore, a feeding pipe is fixedly installed on the top of the flocculant storage box 301, and a sealing plug is installed on the feeding pipe. It should be noted that when adding flocculant, the staff opens the door 8, removes the sealing plug, and then adds flocculant into the flocculant storage box 301 through the feeding pipe. After adding, the feeding pipe is sealed with the sealing plug, and the door 8 is closed.

[0066] In this embodiment:

[0067] When the rotating shaft 201 rotates, it drives the flocculant storage box 301 and the vertical rod 308 to rotate synchronously. Since the screw 309 is fixedly connected to the top frame 5 and threadedly engaged with the vertical rod 308, the vertical rod 308 moves upward along the vertical hole 311 during rotation, driving the piston 307 to move upward and squeezing the flocculant in the flocculant storage box 301. After being squeezed, the flocculant flows into the branch pipe 304 through the main pipe 302 and the hose 303, and is evenly sprayed into the sewage from the addition head 305. At the same time, the piston rod 210 drives the branch pipe 304 to move back and forth synchronously with the stirring component through the connecting piece 306. With the rotational movement of the branch pipe 304, the flocculant is evenly distributed throughout the sewage, avoiding local accumulation of flocculant.

[0068] It should be added that,

[0069] Third Embodiment

[0070] The third embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0071] Please refer to the following: Figures 11-13 In the wastewater treatment test equipment for ice cream production provided in this embodiment, the mixing and enhancing mechanism 4 includes auxiliary component 1 401, auxiliary component 2 402, sleeve plate 403 and mating joint 404. Auxiliary component 1 401 is fixedly connected to auxiliary component 2 402 and mating joint 404. Sleeve plate 403 is fixedly sleeved on the outside of vertical rod 308. Vertical rod 308 is rotatably mounted on auxiliary component 2 402. Sleeve plate 403 is in contact with auxiliary component 2 402. Auxiliary component 1 401 is vertically slidably mounted on wastewater treatment tank 1.

[0072] Furthermore, a top frame 5 is fixedly installed on the top of the wastewater treatment tank 1, and a control panel 6 is fixedly installed on the top of the top frame 5. The auxiliary component 402 is slidably sleeved on the outside of the top frame 5, and the top of the screw 309 is fixedly connected to the top frame 5. It should be noted that the rotation number of the servo motor 202 is set in advance on the control panel 6. After the servo motor 202 reaches the set rotation number, the control panel 6 will control the servo motor 202 to reverse, thus realizing the entire workflow. Moreover, in the initial treatment of ice cream wastewater, experiments are required. The speed of the servo motor 202 can be set in advance in multiple groups. During the experiment, the speed of the servo motor 202 is gradually increased. After the ice cream wastewater is discharged after treatment, the treated ice cream wastewater is sampled and tested. The speed of the servo motor 202 corresponding to the best treatment effect is selected, thus realizing the experimental process of the initial treatment of ice cream wastewater.

[0073] In this embodiment:

[0074] During the upward rotation of the vertical rod 308, the auxiliary component 402 moves synchronously upward along the top frame 5 via the sleeve 403, thereby pulling the auxiliary component 401 and the mating abutment 404 upward slowly. After the mating abutment 404 moves upward, its contact position with the extruded ball 214 changes, such as... Figure 13 As shown, the mating joint 404 has an inclined surface. Therefore, when the mating joint 404 moves upward, the lateral obstruction distance of the extrusion ball 214 increases, which increases the reciprocating stroke of piston rod 209 and piston rod 210. The lateral movement amplitude of the agitator increases accordingly, and the mixing intensity of sewage and flocculant gradually increases, promoting the rapid formation of flocs. When the output end of the servo motor 202 reverses, the lateral movement amplitude of the agitator decreases accordingly. This cycle repeats until the mixing reaction reaches the preset test time. Then, the servo motor 202 is reversed through the control panel 6, which drives the components to reset. The mating joint 404 moves down to the initial position, the agitator stops reciprocating, the drain valve is opened, and the treated sewage is discharged. Water quality indicators are sampled and tested. After cleaning the inside of the sewage treatment tank 1, the next set of process parameters can be tested.

[0075] It should be added that the number of auxiliary parts 401 and corresponding mating joints 404 can be increased in actual use, and they are also arranged in a ring-shaped, equally spaced manner.

[0076] Fourth embodiment

[0077] This embodiment provides a pilot process for wastewater treatment in ice cream production, which includes at least the following steps:

[0078] Step 1: Ice cream wastewater is added to wastewater treatment tank 1, flocculant is added to flocculant storage box 301, servo motor 202 is started, and the shaft 201 rotates through gear 1 203 and gear 2 204, thereby causing the hollow seat 205, piston cylinder 1 206, pipe 207, piston cylinder 2 208, piston rod 1 209, piston rod 2 210, stirring component 1 211, and stirring component 2 212 to rotate synchronously. During the rotation of the extrusion ball 214, the abutment joint 404 will intermittently extrude the extrusion ball 214. During extrusion, piston rod 209 moves, causing crossbar 215 to compress spring 217. Piston rod 209 moves piston rod 210 via flowing hydraulic oil. The movement directions of piston rod 209 and piston rod 210 are opposite. During the process of extruding ball 214 and separating from mating joint 404, spring 217 returns to its original position, allowing piston rod 209 and piston rod 210 to return to their original positions. This causes stirring components 211 and 212 to move laterally and in opposite directions, which can quickly mix flocculant and ice cream wastewater.

[0079] Step 2: During the mixing process, the flocculant storage box 301, main pipe 302, hose 303, branch pipe 304, addition head 305, connector 306, and vertical rod 308 rotate synchronously with the rotating shaft 201. Since the screw 309 is threadedly connected to the vertical rod 308, the vertical rod 308 will move upward when it rotates. The vertical rod 308 drives the piston 307 to move upward. The piston 307 lifts the flocculant in the flocculant storage box 301 upward, so that the flocculant passes through the main pipe 302, hose 303, and branch pipe 304, and is discharged from the addition head 305. In addition, the piston rod 210 drives the branch pipe 304 to move laterally back and forth through the connector 306, and the branch pipe 304 rotates continuously. In this way, the flocculant is evenly added into the wastewater treatment tank 1 from the addition head 305. The addition method is more uniform and can quickly mix the flocculant with the ice cream wastewater.

[0080] Step 3: During the rotation and vertical movement of the vertical rod 308, the sleeve 403 will drive the auxiliary component 2 402 to move vertically in sync. The auxiliary component 2 402 will drive the auxiliary component 1 401 to move, which will cause the mating abutment 404 to move slowly upward. As the mating abutment 404 moves slowly upward, the lateral obstruction distance of the extrusion ball 214 will increase, which will increase the lateral reciprocating frequency of the piston rod 1 209 and the piston rod 210, further improving the efficiency of mixing flocculant with ice cream wastewater.

10. A wastewater treatment experimental process for ice cream production, characterized in that, The experimental wastewater treatment equipment for ice cream production as described in any one of claims 1-9 includes at least the following steps: Step 1: Ice cream wastewater is added to the wastewater treatment tank (1), flocculant is added to the flocculant storage box (301), and the servo motor (202) is started. Through the transmission of gear one (203) and gear two (204), the rotating shaft (201) is rotated, thereby causing the hollow seat (205), piston cylinder one (206), pipe (207), piston cylinder two (208), piston rod one (209), piston rod two (210), stirring component one (211) and stirring component two (212) to rotate synchronously. During the rotation of the extrusion ball (214), the joint (404) will intermittently extrude the extrusion ball (214). When the pressure is applied, the piston rod 1 (209) will move, causing the crossbar (215) to compress the spring (217). The piston rod 1 (209) will also move the piston rod 2 (210) through the flow of hydraulic oil. The piston rod 1 (209) and the piston rod 2 (210) move in opposite directions. During the process of separating the compressed ball (214) from the mating joint (404), the spring (217) will reset, allowing the piston rod 1 (209) and the piston rod 2 (210) to reset. This will cause the stirring element 1 (211) and the stirring element 2 (212) to move laterally and in opposite directions, which can quickly mix the flocculant with the ice cream wastewater. Step 2: During the mixing process, the flocculant storage box (301), main pipe (302), hose (303), branch pipe (304), additive head (305), connector (306), and vertical rod (308) rotate synchronously with the rotating shaft (201). Since the screw (309) is threadedly connected to the vertical rod (308), the vertical rod (308) will move upward when it rotates. The vertical rod (308) drives the piston (307) to move upward, and the piston (307) pushes the flocculant storage box (301) to move upward. 01) The flocculant inside is lifted upward, so that the flocculant passes through the main pipe (302), hose (303) and branch pipe (304) and is discharged from the addition head (305). In addition, the piston rod (210) drives the branch pipe (304) to move laterally back and forth through the connector (306), and the branch pipe (304) rotates continuously, so that the flocculant is evenly added into the sewage treatment tank (1) from the addition head (305). The addition method is more uniform and can quickly mix the flocculant with the ice cream sewage. Step 3: During the rotation and vertical movement of the vertical rod (308), the auxiliary part 2 (402) will move vertically in sync through the action of the sleeve plate (403). The auxiliary part 2 (402) will drive the auxiliary part 1 (401) to move, thereby causing the mating joint (404) to move slowly upward. During the process of the mating joint (404) slowly moving upward, the lateral obstruction distance of the extrusion ball (214) will increase, thereby increasing the lateral reciprocating frequency of piston rod 1 (209) and piston rod 2 (210), further improving the efficiency of mixing flocculant with ice cream wastewater.
