Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, and particularly relates to an efficient sedimentation tank stirring treatment device and a treatment method thereof. Background Technique

[0002] Sedimentation tank stirring treatment is a common water treatment technology. It mainly accelerates the sedimentation process of suspended solids in water through stirring, thereby improving the water quality purification efficiency. Sedimentation tank stirring treatment refers to setting a stirring device in the sedimentation tank. Through the rotation of the stirring blades and the principle of stirring centrifugation, impurities such as heavier sediment in the sewage are gathered at the bottom of the water flow vortex formed by stirring, thereby realizing a treatment method for solid-liquid separation.

[0003] Conventional stirring treatment devices for sedimentation tanks are mainly composed of rotatable stirring blades. During sedimentation, a flocculant is added to achieve the mixing and stirring process. However, when the currently used mixing and stirring device is mixing, its stirring range is limited, resulting in mixing and stirring only being achievable within a certain range. However, during flocculation, the flocculant clusters should move towards the middle of the water body, and the current stirring device cannot fully mix the middle of the water body, affecting the flocculation effect.

[0004] At the same time, when the flocculant reacts with the sewage, flocculant clusters will be generated. In the prior art, a filter screen is used to filter it to separate the filtered water flow and the flocculant clusters. However, during the separation process, the flocculant clusters will be blocked at the water outlet, thereby causing the filter screen to be unable to filter, resulting in the water outlet being blocked and affecting the treatment efficiency. Urgent improvement is needed. Summary of the Invention

[0005] The purpose of the present invention is to provide an efficient sedimentation tank stirring treatment device and a treatment method thereof to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solution: An efficient sedimentation tank stirring treatment device, including a sedimentation tank assembly, a power transmission sleeve is movably sleeved in the middle of the sedimentation tank assembly, a main shaft is fixedly connected to the bottom end of the power transmission sleeve, and extension guide rails are fixedly installed on the outer side surface of the main shaft at equal angles. A power assembly is fixedly installed at a position near the middle of the top end of the sedimentation tank assembly. One end of the power assembly is fixedly sleeved with the outer side surface of the power transmission sleeve. A limit sleeve is fixedly installed at the bottom end of the main shaft. A self-adjusting assembly located on the inner side surface of the power transmission sleeve is movably installed at the top end of the main shaft. Limiting grooves are axially equidistantly formed on the outer side surface of the limit sleeve. A limiting block is arranged inside the limit sleeve. The limiting block is movably clamped with the limiting groove. A linkage rod located inside the limit sleeve is fixedly installed at the top end of the limiting block. The top end of the linkage rod penetrates through the top end of the main shaft, and threaded sleeves are installed on both the left and right sides of the top end of the linkage rod. The threaded sleeves are connected to the self-adjusting assembly. Mixing assemblies are movably clamped inside the extension guide rails. One end of each mixing assembly is connected to the outer side surface of the limiting block.

[0007] As a further technical solution of the present invention, the sedimentation tank assembly includes a sedimentation tank. A frame is fixedly sleeved on the outer side surface of the sedimentation tank. A discharge tank is fixedly communicated with the middle of the bottom end of the sedimentation tank. A filter screen is movably clamped at the bottom end of the inner cavity of the discharge tank. Water inlets are fixedly communicated with both positions near the two sides of the top end of the sedimentation tank. A feed trough located directly below the self-adjusting assembly is formed at a position near the middle of the sedimentation tank.

[0008] When treating sewage, the sewage can be injected into the inside of the sedimentation tank through the water inlets. At the same time, the cleanliness inside the filter screen is maintained, and the feed trough is made to correspond to the self-adjusting assembly, and the device is connected to the power supply to complete the preparations before sewage treatment.

[0009] As a further technical solution of the present invention, the power assembly includes a mounting frame. The bottom end of the mounting frame is connected to the top end of the sedimentation tank. A motor is fixedly installed on the inner side surface of the mounting frame. A power gear is fixedly installed at the output end of the motor. A driven gear ring is meshed and connected to one side of the power gear. The inner side surface of the driven gear ring is fixedly sleeved with the outer side surface of the power transmission sleeve.

[0010] After the sewage injection is completed, the motor can be started to drive the power gear at the bottom to rotate. When the power gear rotates, it can synchronously drive the driven gear ring to rotate. When the driven gear ring rotates, it can drive the power transmission sleeve inside to rotate at a high speed, and drive the main shaft at the bottom to rotate through the power transmission sleeve. At this time, the extension guide rails on the outer side surface of the main shaft rotate circumferentially, and at the same time drive the mixing assemblies to rotate circumferentially, so as to mix the sewage and flocculant inside the sedimentation tank assembly through multiple mixing assemblies.

[0011] As a further technical solution of the present invention, the self-adjusting component includes a flocculant storage tank. The outer side surface of the flocculant storage tank is fixedly sleeved with the inner side surface of the power transmission sleeve. A power shaft is movably connected inside the flocculant storage tank. An impeller located inside the flocculant storage tank is fixedly sleeved on the outer side surface of the power shaft.

[0012] As a further technical solution of the present invention, one end of the flocculant storage tank is fixedly communicated with a feed pipe, and the other end of the flocculant storage tank is fixedly communicated with a discharge pipe located directly above the feed trough. One end of the feed pipe is communicated with an external high-pressure flocculant pipeline.

[0013] As a further technical solution of the present invention, the bottom end of the power shaft penetrates through the bottom end of the flocculant storage tank and is fixedly connected with a driving gear. Both the front and rear ends of the driving gear are meshed with driven gears. The bottom ends of both driven gears are fixedly connected with ball screws. The bottom end of the ball screw is movably connected with the top end of the main shaft. The outer side surface of the ball screw is threadedly sleeved with a threaded sleeve.

[0014] When treating sewage, external flocculant can be injected into the interior of the feed pipe after being pressurized. At this time, after passing through the flocculant storage tank, the flocculant can be discharged through the discharge pipe and introduced into the interior of the feed trough through the discharge pipe, and enter the interior of the sedimentation tank through the feed trough to be mixed with the sewage. At the same time, when the flocculant enters the interior of the flocculant storage tank, it can drive the impeller to rotate. At this time, the driving gear at the bottom end can be driven to rotate. At this time, the driven gears on both sides of the driving gear rotate accordingly, and drive the ball screws at the bottom end to rotate. When the two ball screws rotate, the threaded sleeve can be driven to displace downward, and finally drive the linkage rod and the limit block to displace downward.

[0015] As a further technical solution of the present invention, the mixing component includes a guide block. The guide block is movably clamped with the extension guide rail. Installation rods are fixedly installed at one ends of the guide blocks away from the main shaft. One end of each installation rod penetrates through one side of the extension guide rail and is fixedly connected with a rubber brush. One side of the bottom end of the guide block is fixedly connected with a reinforcing frame. The other end of the reinforcing frame is connected to the inner side surface of the rubber brush.

[0016] As a further technical solution of the present invention, second fixing seats are fixedly installed at the bottom ends of the guide blocks. One ends of the second fixing seats away from the guide blocks are movably connected with connecting rods through rotating shafts. One ends of the connecting rods away from the second fixing seats are movably connected with first fixing seats through rotating shafts. The inner side surfaces of the first fixing seats are fixedly connected with the outer side surfaces of the limit blocks.

[0017] In the initial state, the mixing assembly is in the maximum stirring range, that is, the outer side of the rubber brush is in contact with the inner side of the sedimentation tank at this time, and the area covered by the entire mixing assembly is the maximum value. As the flocculant is injected, that is, when the limit block gradually moves downward, the connecting rod deflects towards the middle at this time. At this time, the guide block is subjected to a tensile force and moves towards the main shaft direction. At this time, the mounting rod and the rubber brush move towards the direction close to the main shaft, and the overall mixing range of the mixing assembly decreases, completing the automatic adjustment process of the mixing range.

[0018] By utilizing the injection process of the flocculant and the cooperation process of the self-adjusting assembly and the mixing assembly, that is, as the flocculant is injected, the limit block is driven to move downward by the action of the self-adjusting assembly, and the mixing range of the mixing assembly is automatically changed, so that the mixing position moves towards the middle of the water body, accelerating the mixing between the flocculant and the sewage, and making the floc mass move towards the middle of the water body, improving the flocculation effect.

[0019] When the flocculation mixing of the sewage is completed, the injection of the flocculant can be stopped, and the driving gear is rotated reversely, thereby driving the two ball screws to rotate reversely. At this time, the two threaded sleeves move upward, and at the same time drive the limit block to move upward. At this time, the water can pass through the filter screen and be discharged through the discharge tank. When the limit block moves upward, the connecting rod deflects towards the direction away from the middle and pushes the guide block to move away from the main shaft direction. At the same time, it drives the mounting rod and the rubber brush to move towards the direction close to the sedimentation tank until the outer side of the rubber brush is in contact with the inner side of the sedimentation tank, and the inner side wall of the sedimentation tank can be cleaned by the circumferential rotation of the mixing assembly.

[0020] By utilizing the reset process of the device, that is, when the self-adjusting assembly is reset, it can drive the mixing assembly to be automatically reset, and cooperate with the circumferential rotation of the mixing assembly to realize the automatic cleaning process of the sedimentation tank. The entire cleaning process can be completed only by resetting the device, which can effectively reduce the problem that the floc mass adheres to the inner side of the sedimentation tank after each flocculation treatment, reduce the subsequent maintenance times, and improve the overall flocculation efficiency.

[0021] As a further technical solution of the present invention, a prolonging rod is fixedly installed in the middle of the bottom end of the limit block. The bottom end of the prolonging rod penetrates through the bottom end of the limit sleeve and is fixedly connected with a sealing plug. A cleaning column located directly above the filter screen is fixedly installed at the bottom end of the sealing plug. The diameter of the sealing plug is the same as the diameter of the discharge tank.

[0022] Meanwhile, with the injection of the flocculant, the limit block moves downward accordingly, which can drive the extension rod and the sealing plug to move downward synchronously. At this time, the cleaning column at the bottom of the sealing plug can move downward synchronously. When the cleaning column moves into the filter screen, it can actively clean the filter screen, reduce the blockage inside the discharge tank, and only seal the bottom of the discharge tank to ensure the correct sewage flocculation mixing process.

[0023] By reusing the injection process of the flocculant, that is, the cooperation between the self-adjusting component and the limit block to achieve the downward displacement of the limit block, the active downward movement of the sealing plug and the cleaning column can be realized, and the filter screen can be automatically cleaned by the action of the cleaning column. The whole process is automatically completed, which can significantly reduce the blockage of the discharge tank and thus improve the overall treatment efficiency.

[0024] A treatment method for an efficient sedimentation tank stirring treatment device includes the following steps:

[0025] S1: When treating sewage, the sewage needs to be injected into the sedimentation tank through the water inlet, and the high-pressure flocculant is introduced into the feeding pipe to complete the preparation before treatment;

[0026] S2: When treating sewage, the external high-pressure flocculant pipeline can be opened to introduce the flocculant into the sedimentation tank through the discharge pipe and the feeding trough to mix it with the sewage. Then, the installation frame is activated to drive the power gear to rotate, which finally drives the driven gear ring and the power transmission sleeve to rotate. The main shaft and the extension guide rail rotate accordingly, and drive the mixing component to rotate circumferentially to complete the mixing process of the sewage and the flocculant;

[0027] S3: During the flocculation process, with the introduction of the high-pressure flocculant, the impeller rotates, which drives the driving gear to rotate, and then drives the two driven gears to rotate until the ball screw rotates. At this time, the threaded sleeve can move up and down relative to the main shaft. When the threaded sleeve moves downward, it can drive the linkage rod and the limit block to move downward synchronously. At this time, the connecting rod deflects accordingly, and drives the mounting rod and the rubber brush to move towards the main shaft, reducing the stirring range and improving the flocculation effect;

[0028] S4: Meanwhile, when the limit block moves downward, it can drive the sealing plug and the cleaning column to move downward. When the cleaning column moves downward, it can automatically clean the filter screen and reduce the blockage of the discharge tank.

[0029] The beneficial effects of the present invention are as follows:

[0030] (1) The present invention utilizes the injection process of the flocculant and the cooperation process of the self-adjusting component and the mixing component. That is, as the flocculant is injected, the limiting block is driven to displace downward by the action of the self-adjusting component, and the mixing range of the mixing component is automatically changed, so that the mixing position displaces towards the middle of the water body, accelerating the mixing between the flocculant and the sewage, and making the floc mass displace towards the middle of the water body, improving the flocculation effect.

[0031] (2) The present invention utilizes the reset process of the device. That is, when the self-adjusting component resets, it can drive the mixing component to automatically reset, and cooperate with the circumferential rotation of the mixing component to achieve the automatic cleaning process of the sedimentation tank. The entire cleaning process can be completed only by resetting the device, which can effectively reduce the problem that the floc mass adheres to the inner side of the sedimentation tank after numerous flocculation treatments each time, reduce the subsequent maintenance times, and improve the overall flocculation efficiency.

[0032] (3) The present invention re-utilizes the injection process of the flocculant. That is, through the cooperation of the self-adjusting component and the limiting block, the downward displacement of the limiting block is achieved, and then the active downward movement of the sealing plug and the cleaning column can be realized, and the filter screen is automatically cleaned through the action of the cleaning column. The whole process is automatically completed, which can significantly reduce the blockage of the discharge tank, and thus improve the overall treatment efficiency. Description of the Drawings

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] As Figures 1 to 10 shown, in the embodiment of the present invention, an efficient sedimentation tank stirring treatment device includes a sedimentation tank assembly 1. A power transmission sleeve 7 is movably sleeved in the middle of the sedimentation tank assembly 1. The bottom end of the power transmission sleeve 7 is fixedly connected to a main shaft 4. Extension guide rails 5 are fixedly installed on the outer side surface of the main shaft 4 at equal angles. A power assembly 3 is fixedly installed at a position near the middle of the top end of the sedimentation tank assembly 1. One end of the power assembly 3 is fixedly sleeved with the outer side surface of the power transmission sleeve 7. A limit sleeve 6 is fixedly installed at the bottom end of the main shaft 4. A self-adjusting assembly 8 located on the inner side surface of the power transmission sleeve 7 is movably installed at the top end of the main shaft 4. Limit grooves 9 are axially equidistantly opened on the outer side surface of the limit sleeve 6. A limit block 10 is arranged inside the limit sleeve 6. The limit block 10 is movably clamped with the limit groove 9. A linking rod 11 located inside the limit sleeve 6 is fixedly installed at the top end of the limit block 10. The top end of the linking rod 11 penetrates through the top end of the main shaft 4. Threaded sleeves 12 are installed on both the left and right sides of the top end of the linking rod 11. The threaded sleeves 12 are connected to the self-adjusting assembly 8. Mixing components 16 are movably clamped inside the extension guide rails 5. One end of the mixing component 16 is connected to the outer side surface of the limit block 10.

[0046] As Figure 1 and Figure 2 as well as Figure 3 and Figure 4 As shown, the sedimentation tank assembly 1 includes a sedimentation tank 101. A frame 2 is fixedly sleeved on the outer side surface of the sedimentation tank 101. A discharge tank 102 is fixedly communicated with the middle of the bottom end of the sedimentation tank 101. A filter screen 103 is movably clamped at the bottom end of the inner cavity of the discharge tank 102. Water inlets 104 are fixedly communicated with both positions near the two sides of the top end of the sedimentation tank 101. A feed trough 105 located directly below the self-adjusting assembly 8 is opened at a position near the middle of the sedimentation tank 101.

[0047] When treating sewage, the sewage can be injected into the interior of the sedimentation tank 101 through the water inlets 104. At the same time, the cleanliness inside the filter screen 103 is maintained. The feed trough 105 is corresponded with the self-adjusting assembly 8, and the device is connected to the power supply to complete the preparation before sewage treatment.

[0048] As Figure 1 and Figure 3 as well as Figure 4 As shown, the power assembly 3 includes a mounting frame 301. The bottom end of the mounting frame 301 is connected to the top end of the sedimentation tank 101. A motor 302 is fixedly installed on the inner side surface of the mounting frame 301. A power gear 303 is fixedly installed at the output end of the motor 302. A driven gear ring 304 is meshed and connected to one side of the power gear 303. The inner side surface of the driven gear ring 304 is fixedly sleeved on the outer side surface of the power transmission sleeve 7.

[0049] After the sewage injection is completed, the motor 302 can be started to drive the power gear 303 at the bottom end to rotate. When the power gear 303 rotates, the driven gear ring 304 can be synchronously driven to rotate. When the driven gear ring 304 rotates, the power transmission sleeve 7 inside can be driven to rotate at a high speed, and the main shaft 4 at the bottom end can be driven to rotate through the power transmission sleeve 7. At this time, the extension guide rail 5 on the outer side surface of the main shaft 4 rotates circumferentially, and at the same time drives the mixing assembly 16 to rotate circumferentially, so that the sewage and the flocculant inside the sedimentation tank assembly 1 can be mixed by a plurality of mixing assemblies 16.

[0050] As Figure 3 and Figure 5 as well as Figure 6 and Figure 7As shown, the self-adjusting component 8 includes a flocculant storage tank 801. The outer side of the flocculant storage tank 801 is fixedly sleeved with the inner side of the power transmission sleeve 7. A power shaft 804 is movably connected inside the flocculant storage tank 801. An impeller 805 located inside the flocculant storage tank 801 is fixedly sleeved on the outer side of the power shaft 804. One end of the flocculant storage tank 801 is fixedly communicated with a feed pipe 802, and the other end of the flocculant storage tank 801 is fixedly communicated with a discharge pipe 803 located directly above the feed trough 105. One end of the feed pipe 802 is communicated with an external high-pressure flocculant pipeline. The bottom end of the power shaft 804 penetrates the bottom end of the flocculant storage tank 801 and is fixedly connected with a driving gear 806. Both the front and rear ends of the driving gear 806 are meshed with driven gears 807. The bottom ends of both driven gears 807 are fixedly connected with ball screws 808. The bottom ends of the ball screws 808 are movably connected with the top end of the main shaft 4. The outer side of the ball screw 808 is threadedly sleeved with a threaded sleeve 12.

[0051] When treating sewage, the external flocculant can be kept injected into the interior of the feed pipe 802 after being pressurized. At this time, after passing through the flocculant storage tank 801, the flocculant can be discharged through the discharge pipe 803 and introduced into the interior of the feed trough 105 through the discharge pipe 803, and enter the interior of the sedimentation tank 101 through the feed trough 105 to be mixed with the sewage. At the same time, when the flocculant enters the interior of the flocculant storage tank 801, it can drive the impeller 805 to rotate. At this time, the driving gear 806 at the bottom end can be driven to rotate. At this time, the driven gears 807 on both sides of the driving gear 806 rotate accordingly, driving the ball screws 808 at the bottom end to rotate. When the two ball screws 808 rotate, the threaded sleeve 12 can be driven to move downward, and finally drive the linkage rod 11 and the limit block 10 to move downward.

[0052] As Figure 6 and Figure 8 as well as Figure 9 and Figure 10 shown, the mixing component 16 includes a guide block 161. The guide block 161 is movably clamped with the extension guide rail 5. Installation rods 162 are fixedly installed at the ends of the guide block 161 away from the main shaft 4. One end of the installation rod 162 penetrates one side of the extension guide rail 5 and is fixedly connected with a rubber brush 163. One side of the bottom end of the guide block 161 is fixedly connected with a reinforcing frame 164. The other end of the reinforcing frame 164 is connected to the inner side of the rubber brush 163. Second fixing seats 166 are fixedly installed at the bottom ends of the guide block 161. The ends of the connecting rods 167 away from the second fixing seats 166 are movably connected with the first fixing seats 165 through rotating shafts. The inner sides of the first fixing seats 165 are fixedly connected with the outer sides of the limit blocks 10.

[0053] Embodiment: In the initial state, the mixing assembly 16 is in the maximum stirring range, that is, at this time, the outer side surface of the rubber brush 163 is in contact with the inner side surface of the sedimentation tank 101, and the area covered by the entire mixing assembly 16 is the maximum value. As the flocculant is injected, that is, when the limit clamping block 10 gradually moves downward, at this time, the connecting rod 167 deflects toward the middle accordingly. At this time, the guide block 161 is subjected to a pulling force and moves toward the main shaft 4. At this time, the mounting rod 162 and the rubber brush 163 move toward the direction close to the main shaft 4 accordingly, and the overall mixing range of the mixing assembly 16 decreases, completing the automatic adjustment process of the mixing range.

[0054] By utilizing the injection process of the flocculant and the cooperation process of the self-adjusting assembly 8 and the mixing assembly 16, that is, as the flocculant is injected, the limit clamping block 10 is driven to move downward by the action of the self-adjusting assembly 8, and the mixing range of the mixing assembly 16 is automatically changed, so that the mixing position moves toward the middle of the water body, accelerating the mixing between the flocculant and the sewage, and making the floc mass move toward the middle of the water body, improving the flocculation effect.

[0055] When the flocculation mixing of the sewage is completed, the injection of the flocculant can be stopped, and the driving gear 806 is rotated reversely, thereby driving the two ball screws 808 to rotate reversely. At this time, the two threaded sleeves 12 move upward accordingly, and at the same time drive the limit clamping block 10 to move upward. At this time, the water flow can pass through the filter screen 103 and be discharged through the discharge tank 102. When the limit clamping block 10 moves upward, the connecting rod 167 deflects toward the direction away from the middle and pushes the guide block 161 to move away from the main shaft 4. At the same time, it drives the mounting rod 162 and the rubber brush 163 to move toward the direction close to the sedimentation tank 101 until the outer side surface of the rubber brush 163 is in contact with the inner side surface of the sedimentation tank 101, and the inner side wall of the sedimentation tank 101 can be cleaned by the circumferential rotation of the mixing assembly 16.

[0056] By utilizing the reset process of the device, that is, when the self-adjusting assembly 8 is reset, it can drive the mixing assembly 16 to be automatically reset, and cooperate with the circumferential rotation of the mixing assembly 16 to realize the automatic cleaning process of the sedimentation tank 101. The entire cleaning process only needs to reset the device to complete, which can effectively reduce the problem that the floc mass adheres to the inner side surface of the sedimentation tank 101 after each flocculation treatment, reduce the subsequent maintenance times, and improve the overall flocculation efficiency.

[0057] Such as Figure 3 and Figure 5 and Figure 8As shown in the figure, a prolonging rod 13 is fixedly installed in the middle of the bottom end of the limit clamping block 10. The bottom end of the prolonging rod 13 penetrates through the bottom end of the limit sleeve 6 and is fixedly connected with a sealing plug 14. A cleaning column 15 located directly above the filter screen 103 is fixedly installed at the bottom end of the sealing plug 14. The diameter of the sealing plug 14 is the same as that of the discharging tank 102.

[0058] Embodiment: Meanwhile, with the injection of the flocculant, the limit clamping block 10 moves downward accordingly, and at the same time, it can drive the prolonging rod 13 and the sealing plug 14 to move downward. At this time, the cleaning column 15 at the bottom end of the sealing plug 14 can move downward synchronously. When the cleaning column 15 moves into the interior of the filter screen 103, the filter screen 103 can be actively cleaned, reducing the blockage inside the discharging tank 102. At the same time, only the bottom end of the discharging tank 102 needs to be sealed to ensure the correct progress of the sewage flocculation mixture.

[0059] By reusing the injection process of the flocculant, that is, the cooperation between the self-adjusting component 8 and the limit clamping block 10, the downward displacement of the limit clamping block 10 is realized, so that the sealing plug 14 and the cleaning column 15 can move downward actively, and the filter screen 103 is automatically cleaned by the action of the cleaning column 15. The whole process is automatically completed, which can significantly reduce the blockage of the discharging tank 102 and thus improve the overall treatment efficiency.

[0060] A treatment method for an efficient sedimentation tank stirring treatment device includes the following steps:

[0061] S1: When treating sewage, the sewage needs to be injected into the interior of the sedimentation tank 101 through the water inlet 104, and the high-pressure flocculant is introduced into the interior of the feed pipe 802 to complete the preparation before treatment;

[0062] S2: When treating sewage, the external high-pressure flocculant pipeline can be opened to introduce the flocculant into the interior of the sedimentation tank 101 through the discharge pipe 803 and the feed trough 105 to mix it with the sewage. At the same time, the motor 302 is started to drive the power gear 303 to rotate, and finally drive the driven gear ring 304 and the power transmission sleeve 7 to rotate. The main shaft 4 and the extension guide rail 5 rotate accordingly, and drive the mixing component 16 to rotate circumferentially to complete the mixing process of the sewage and the flocculant;

[0063] S3: During the flocculation process, with the introduction of the high-pressure flocculant, the impeller 805 rotates accordingly, and at the same time drives the driving gear 806 to rotate, and drives the two driven gears 807 to rotate until the ball screw 808 rotates. At this time, the threaded sleeve 12 can move up and down relative to the main shaft 4. When the threaded sleeve 12 moves downward, it can drive the linkage rod 11 and the limit clamping block 10 to move downward synchronously. At this time, the connecting rod 167 deflects accordingly, and drives the mounting rod 162 and the rubber brush 163 to move towards the direction close to the main shaft 4, narrowing the stirring range and improving the flocculation effect;

[0064] S4: Meanwhile, when the limit catch block 10 moves downward, it can drive the sealing plug 14 and the cleaning column 15 to move downward. When the cleaning column 15 moves downward, the filter screen 103 can be automatically cleaned, reducing the blockage of the discharge tank 102.

[0065] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
