Description

Technical Field

[0001] This invention relates to the field of wastewater treatment for water ring vacuum pumps, and more specifically, to a wastewater treatment device and method for using water ring vacuum pumps. Background Technology

[0002] A water ring vacuum pump is a vacuum device that uses a rotating liquid ring formed by water to draw in and compress gas. Its core function is to create a vacuum environment or transport gas. Its working principle is that a motor drives an impeller to rotate, causing the water inside the pump body to form a rotating liquid ring that adheres tightly to the inner wall. A periodically changing volume chamber is formed between the liquid ring and the impeller blades, thus completing the cycle of intake, compression, and exhaust.

[0003] In actual use, a large amount of dust in the gas will come into contact with the water ring and then dissolve into it. If the impurities in the water ring are not discharged, it will cause blockage and affect the use. The current conventional method is to add flocculants to the wastewater to form suspended solids, and then use static sedimentation to filter out the suspended solids. However, the above method has the following two problems in actual operation:

[0004] Problem 1: The wastewater is circulating, which means that flocculant needs to be added to the mixing container continuously. This results in waste due to the continuous addition of flocculant, and the mixing effect between the two is poor due to the flow of wastewater.

[0005] Question 2: A separate settling container is required, but settling takes a long time and the container takes up a lot of space, which has a significant impact on usage. Summary of the Invention

[0006] To overcome the above shortcomings, the present invention provides a water ring vacuum pump wastewater treatment equipment and its usage method, aiming to improve the problems of flocculant waste, insufficient mixing, long settling time and large settling container in the prior art.

[0007] This invention is implemented as follows:

[0008] This invention provides a wastewater treatment device for a water ring vacuum pump, including a mounting frame disposed below the vacuum pump. A wastewater processor is installed within the mounting frame. The wastewater processor is connected to the outlet and inlet of the vacuum pump via an inlet pipe and an outlet pipe, respectively. The wastewater processor includes:

[0009] The ring seat has a connected centrifugal processing chamber, an impurity collection chamber and a treated water chamber inside. The centrifugal processing chamber and the impurity collection chamber are both horizontally arranged. The impurity collection chamber is located below the centrifugal processing chamber, and the treated water chamber is arranged in a ring around the centrifugal processing chamber and the impurity collection chamber.

[0010] The centrifuge seat rotates inside the centrifuge processing chamber and consists of a central ring and multiple sets of isolation seats arranged radially thereon. Multiple dust collection protrusions are provided along the length of one side of the isolation seats, and dust collection grooves are formed inside the dust collection protrusions.

[0011] The impurity removal rod adheres to the inner wall of the dust collection trough and slides along the length of the dust collection trough, pushing the impurities in the dust collection trough into the impurity collection chamber in the ring seat.

[0012] Preferably, the number of centrifuge chambers is at least two, and they are distributed vertically.

[0013] The centrifugal processing chamber is provided with a liquid outlet, which is connected to the water treatment chamber.

[0014] A sealing ring is slidably mounted inside the water treatment chamber. The sealing ring has an annular opening. When the annular opening is connected to the liquid outlet, the centrifugal treatment chamber and the water treatment chamber are connected.

[0015] Preferably, the ring seat is provided with a motor-driven central shaft, which is connected to the centrifugal seat via a connecting rib.

[0016] Preferably, the centrifuge chamber is provided with a liquid inlet, and a control component for controlling the opening of the liquid inlet is provided at the liquid inlet.

[0017] Preferably, one end of the water inlet pipe is connected to the center of the ring seat, and the outer diameter of the central shaft is smaller than the inner diameter of the ring seat; the other end of the water inlet pipe is connected to the water outlet of the vacuum pump.

[0018] Preferably, the water outlet pipe is connected to the top of the water treatment chamber and the water inlet of the vacuum pump;

[0019] The water treatment chamber is also connected to a water supply pipe.

[0020] Preferably, the dust collection protrusion consists of a "U"-shaped connecting strip fixed on the isolation seat and an outer extension strip perpendicular to its horizontal end.

[0021] Preferably, the centrifuge chamber is provided with an impurity outlet, and the impurity outlet and the impurity collection chamber are connected by a sealing member. When the sealing member is touched by the impurity removal rod, the impurities enter the centrifuge chamber.

[0022] Preferably, the isolation seat has a plurality of flow guiding protrusions on the side away from the dust collection protrusion, the flow guiding protrusions include flow guiding slopes, and the flow guiding slopes are arranged toward the dust collection protrusion.

[0023] This invention also discloses a method of using a water ring vacuum pump wastewater treatment device, comprising the following steps:

[0024] First, the wastewater flowing out of the vacuum pump outlet flows to the wastewater processor through the inlet pipe, and then flows into the centrifugal treatment chamber containing the centrifugal seat. The centrifugal seat and the inner wall of the centrifugal treatment chamber form multiple wastewater treatment chambers.

[0025] Next, flocculant is injected into the wastewater treatment chamber. By rotating the centrifuge seat in both directions, the wastewater and flocculant in the wastewater treatment chamber are fully mixed, and the impurities in the wastewater combine with the flocculant to form suspended solids.

[0026] Secondly, the centrifugal seat is driven to rotate in one direction, causing the suspended matter to gather in the dust collection tank under the action of centrifugal force. The suspended matter in the dust collection tank is guided to the impurity collection chamber by the reciprocating up and down moving impurity removal rod until the suspended matter in the dust collection tank is cleaned up.

[0027] Finally, the purified water is directed to the treatment chamber, and the water is used to replenish the vacuum pump to form a water ring through the outlet pipe.

[0028] The beneficial effects of this invention are:

[0029] In this invention, wastewater is guided into a sealed wastewater centrifugal treatment chamber. The centrifuge unit further divides the wastewater into multiple separate, enclosed chambers. A specific amount of flocculant is added to each of these chambers, and the mixture of impurities and flocculant in the wastewater is achieved as the centrifuge unit rotates. Compared to existing technologies, this invention allows for the mixing of wastewater and flocculant within a closed space, where a specific amount of flocculant can be added. This ensures controllable flocculant usage and guarantees thorough mixing within the separate, enclosed space.

[0030] Furthermore, based on the centrifuge base, the wastewater treatment stage employs multiple segmented wastewater treatment chambers for individual and thorough mixing. After mixing, centrifugal force collects suspended impurities into a dust collection tank within the wastewater treatment chamber. Combined with a reciprocating impurity removal rod, the suspended impurities in the dust collection tank are transferred to an impurity collection chamber, thus achieving rapid collection and treatment of suspended impurities. Compared to existing static methods, this accelerates the process. Simultaneously, it ensures water circulation between the vacuum pump and the wastewater processor, reducing the overall volume during use. This means that rapid response and filtration of suspended impurities during water circulation eliminates the need for static containers, further reducing the usable volume.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example

[0040] Reference Figures 1-5 A water ring vacuum pump wastewater treatment device is provided, with an installation frame 1 below the vacuum pump. Multiple installation strips are provided on the top of the installation frame 1. The installation strips are connected to the water ring vacuum pump by multiple bolts. Thus, the installation frame 1 not only provides installation space for the subsequent wastewater treatment, but also serves as a support structure for the water ring vacuum pump.

[0041] The structure of the mounting frame 1 is a frame structure with an internal cavity. The mounting strip is fixed to the top of the frame structure, and the outer wall of the mounting frame 1 is provided with an opening and locking mounting door to facilitate the subsequent installation of the wastewater processor.

[0042] After the installation frame 1 is set up, it is convenient to treat the wastewater of the water ring vacuum pump. Therefore, this application also sets up a wastewater processor, which is set up in the installation frame 1. At the same time, the wastewater processor in this application is improved compared with the wastewater treatment device in the prior art. It can quickly filter out impurities in the wastewater and recover the filtered impurities. That is, the wastewater processor of this application can quickly respond to the filtration process and accelerate the filtration of suspended impurities in the wastewater, so as to make a rapid response to the water inlet when the water ring vacuum pump is working, and avoid the setting of a large-volume water storage structure.

[0043] In some implementations, the wastewater processor mainly comprises three parts: a ring seat 2, a centrifuge seat 3, and a cleaning rod 4. Based on these three components, the wastewater can be rapidly treated and the suspended solids and impurities can be quickly removed after treatment.

[0044] It should be noted that the inlet pipe of the wastewater processor is connected to the outlet pipe of the vacuum pump, and further, the outlet pipe of the wastewater processor is connected to the inlet pipe of the vacuum pump. Based on this interconnected structural design, wastewater from the vacuum pump can be introduced into the wastewater processor for rapid purification. The purified water then flows back into the vacuum pump, thus achieving a circulation of water between the vacuum pump and the wastewater processor.

[0045] Reference Figure 2 The ring seat 2 is equipped with a centrifugal treatment chamber 20, an impurity collection chamber 22 and a treated water chamber 21. The centrifugal treatment chamber 20 is a cavity structure for wastewater treatment, the impurity collection chamber 22 is a structure for collecting suspended impurities, and the treated water chamber 21 is a storage chamber for the treated water. That is, the water treated by the centrifugal treatment chamber 20 flows into the treated water chamber 21 and is then introduced into the inlet of the vacuum pump.

[0046] The centrifugation chamber 20, the impurity collection chamber 22, and the treated water chamber 21 are positioned and structured as follows:

[0047] 1. The centrifugal processing chamber 20 is an annular structure set on the inner wall of the ring seat 2, and is connected to the internal cavity of the ring seat 2.

[0048] 2. The impurity collection chamber 22 is located directly below the centrifugation chamber 20 and inside the ring seat 2. It is a separate cavity structure.

[0049] 3. The water treatment chamber 21 is located outside the ring seat 2. Specifically, the water treatment chamber 21 is arranged in a ring around the centrifugal treatment chamber 20 and the impurity collection chamber 22, that is, the height of the water treatment chamber 21 is greater than the height of the centrifugal treatment chamber 20 and the impurity collection chamber 22.

[0050] In some embodiments, the centrifuge seat 3 is a hybrid structure that rotates within the centrifugation chamber 20, consisting of a central ring 30 and multiple radially arranged isolation seats 31. The inner diameter of the central ring 30 is the same as the inner diameter of the ring seat 2, and the outer wall of the isolation seats 31 fits against the inner wall of the centrifugation chamber 20. To ensure sealing, a sealing layer is provided on the outer wall of the isolation seats 31. (Refer to...) Figure 3 Then, the inner walls of the two adjacent isolation seats 31, the central ring 30 and the centrifugal treatment chamber 20 form a small wastewater treatment chamber 7.

[0051] Furthermore, the centrifuge seat 3 is rotatable, and when the centrifuge seat 3 rotates, it aggregates the suspended impurities in the wastewater, thereby facilitating the cleaning of the impurity removal rod 4.

[0052] In some embodiments, the structural basis for agglomerating suspended impurities when the centrifugal seat 3 rotates is a dust collection protrusion 32. The dust collection protrusion 32 is arranged along the length of one side of the isolation seat 31. Further, the dust collection protrusion 32 consists of a "7"-shaped connecting strip 321 fixed on the isolation seat 31 and an outward extension strip 322 perpendicular to its horizontal end. (Refer to...) Figure 3 The end of the outer extension strip 322 is left with a gap between it and the side wall of the isolation seat 31. This gap is reserved to facilitate the collection of suspended impurities into the “7”-shaped connecting strip 321.

[0053] In other embodiments, the shape of the "7"-shaped connecting strip 321 can also be ">", that is, it can be matched with any shape that can form a "concave" groove on the side wall of the isolation seat 31. The formed "concave" groove is used to collect suspended impurities. The "concave" groove structure is a dust collection tank 320. Furthermore, in order to facilitate the outflow of water in the "concave" groove structure, the inner wall of the "concave" groove is provided with an overflow port to continuously discharge the water in the "concave" groove, thereby continuously providing space for the collection of suspended impurities.

[0054] Reference Figure 3 and Figure 5 The impurity removal rod 4 fits against the inner wall of the dust collection tank 320 and slides along the length of the dust collection tank 320. Specifically, the outer dimensions of the impurity removal rod 4 are completely fitted with the inner wall of the "concave" groove structure of the dust collection tank 320. As the impurity removal rod 4 moves downward, the suspended impurities in the dust collection tank 320 are pushed downward by the bottom of the impurity removal rod 4 and then enter the impurity collection chamber 22. The suspended impurities are cleaned from the wastewater treatment chamber 7 and collected into the impurity collection chamber 22.

[0055] Furthermore, the centrifuge chamber 20 is provided with an impurity outlet, and the impurity outlet and the impurity collection chamber 22 are connected by a sealing member, wherein the sealing member is a plugging member, that is, its outer diameter is the same as the inner diameter of the impurity outlet and the same as the outer diameter of the impurity removal rod 4. It is connected in the impurity collection chamber 22 by a spring member and slides on the vertical constraint rod, and the spring is sleeved on the vertical constraint rod.

[0056] When the sealing element is pressed against the impurity removal rod 4, the sealing element moves into the impurity collection chamber 22, thereby allowing the suspended impurities at the bottom of the impurity removal rod 4 to enter the centrifugal processing chamber 20. In addition, by providing a fan or a pump to generate airflow or water flow, airflow or water flow is generated below the impurity removal rod 4, making it easier to separate the suspended impurities from the impurity removal rod 4 and the sealing element.

[0057] It should be added that: 1. Since the outer diameter of the sealing part, the inner diameter of the impurity outlet, and the outer diameter of the impurity removal rod 4 are the same, when the impurity removal rod 4 enters the impurity outlet, the outer wall of the impurity removal rod 4 and the inner wall of the impurity outlet fit together. This can prevent the water in the wastewater treatment chamber 7 from flowing into the impurity collection chamber 22 below. In some embodiments, a rubber sealing layer can also be provided on the outer wall of the impurity removal rod 4; 2. The ring seat 2 also includes a rotating ring body. The central ring 30 and the isolation seat 31 are fixed on the top of the rotating ring body, and the impurity collection chamber 22 is located in the rotating ring body. That is, the rotating ring body makes it easy to set the impurity collection chamber 22, and ensures that the impurity collection chamber 22 and the wastewater treatment chamber 7 are always in a relatively static state; 3. When the impurity removal rod 4 moves downward, it will drive the sealing part to move into the impurity collection chamber 22 through the suspended impurities below its bottom. The suspended impurities then flow from the bottom of the impurity removal rod 4 and the top of the sealing part into the impurity collection chamber 22.

[0058] As the impurity removal rod 4 moves downward, the suspended impurities at its bottom are continuously compressed. During the compression process, some of the suspended impurities will detach from the dust collection tank 320, that is, flow out from the gap between the end of the outer extension strip 322 and the side wall of the isolation seat 31. Only the completely compressed suspended impurities can push the sealing component downward. To reduce the amount of suspended impurities flowing out of the dust collection tank 320, the structure of the impurity removal rod 4 and the sealing component is designed as follows:

[0059] The impurity removal rod 4 consists of two parts: an outer cylinder 40 and an inner core 41. The inner core 41 slides up and down along the hollow inner wall of the outer cylinder 40. When the inner core 41 is at the top of the outer cylinder 40, a collection area 42 is formed between the bottom of the inner core 41 and the inner wall of the outer cylinder 40. At this time, when the impurity removal rod 4 moves downward as a whole, the suspended impurities at the bottom of the impurity removal rod 4 will enter the collection area 42 and will not flow out from the sides, thus completing the collection. The process of discharging suspended impurities is as follows: after the outer cylinder 40 is stationary, the inner core 41 moves downward, and the suspended impurities in the collection area 42 are squeezed out of the collection area 42 by the squeezing force at the bottom of the inner core 41.

[0060] Secondly, refer to Figure 5The improved design of the sealing component in conjunction with the impurity removal rod 4 is as follows: The sealing component also consists of two parts, namely an outer ring shell and an inner baffle core. The outer ring shell is vertically connected to the impurity collection chamber 22 by a constraint rod and a spring, while the inner baffle core is connected to the outer ring shell by an elastic telescopic component, which can be a telescopic rod with a spring or a sliding rod in conjunction with a spring. During operation, the impurity removal rod 4 containing suspended impurities in the collection area 42 moves downward as a whole. When the outer cylinder 40 touches the outer ring shell, it drives the outer ring shell to move synchronously into the impurity collection chamber 22. Then, the inner core 41 moves downward, and the suspended impurities in the collection area 42 are squeezed out downward. During the squeezing process, the inner baffle core moves downward relative to the outer ring shell. When a height difference is formed between the inner baffle core and the outer ring shell, the suspended impurities flow from the gap between the inner baffle core and the outer ring shell into the impurity collection chamber 22 until the suspended impurities in the collection area 42 are completely discharged.

[0061] In some implementations, the structure for vertically driving the rear cleaning rod 4 is composed of a linear drive assembly or a driven component.

[0062] The linear drive assembly is a linear drive component such as a push rod motor or a cylinder. Specifically, both the outer cylinder 40 and the inner core 41 are driven by the linear drive assembly.

[0063] When the linear drive assembly is the driven component, the top of the centrifugal seat 3 is provided with a top ring. The outer cylinder 40 of the impurity removal rod 4 slides vertically elastically on the top ring, and the inner core 41 slides elastically on the outer cylinder 40. Specifically, the elastic sliding of the outer cylinder 40 and the inner core 41 can be the same as the elastic sliding structure of the outer ring shell and the inner retaining core, both of which are composed of a spring-loaded telescopic rod or slide rod in conjunction with a spring. The specific setting position and method are conventional and will not be described in detail here. Furthermore, the top of the centrifugal processing chamber 20 is provided with an annular groove, in which a boss structure 8 is provided. The boss structure 8 is provided with an inclined surface 80 and an inner core guide groove 81. When the impurity removal rod 4 rotates with the centrifugal seat 3, when the outer cylinder 40 of the impurity removal rod 4 slides along the inclined surface 80, it drives the outer cylinder 40 of the impurity removal rod 4 to move vertically downward. The starting position of the inner core guide groove 81 is located behind the starting position of the inclined surface 80. When the outer cylinder 40 of the impurity removal rod 4 moves vertically downward into the impurity collection chamber 22, it rotates with the centrifugal seat 3. The outer cylinder 40 of the impurity removal rod 4 slides along the flat end of the bottom of the boss structure 8, while the inner core 41 of the impurity removal rod 4 slides along the inclined surface of the inner core guide groove 81, thereby driving the inner core 41 to slide relative to the outer cylinder 40, thereby squeezing out the suspended impurities in the collection area 42.

[0064] In this embodiment, in order to separate the wastewater treatment process and the effluent stage, there are at least two centrifugal treatment chambers 20, which are distributed vertically. After the wastewater treatment is completed in at least one centrifugal treatment chamber 20, the treated water is discharged into the treatment water chamber 21. The remaining centrifugal treatment chambers 20 are used for the wastewater treatment process. This separates the wastewater treatment and the discharge of the purified water, so that they do not interfere with each other and ensure the adequacy of wastewater treatment (compared to a single centrifugal treatment chamber 20).

[0065] Furthermore, a liquid outlet is provided around the centrifugal processing chamber 20, which communicates with the water treatment chamber 21. Correspondingly, a sealing ring 5 slides vertically within the water treatment chamber 21. The sealing ring 5 can be driven vertically by existing linear drive components such as screws, electric push rods, or cylinders. Furthermore, the sealing ring 5 has an annular opening 50. When the annular opening 50 communicates with the liquid outlet, the centrifugal processing chamber 20 and the water treatment chamber 21 are connected. By switching the position of the sealing ring 5, the communication between the annular opening 50 and the liquid outlet of different centrifugal processing chambers 20 is changed, thus switching the communication between different centrifugal processing chambers 20 and the water treatment chamber 21. Multiple connecting posts are fixed within the annular opening 50 to ensure a stable connection between the upper and lower ends of the annular opening 50.

[0066] It should be added that: the centrifugal processing chamber 20 is preferably set to two. When the annular port 50 is aligned with the liquid outlet of one centrifugal processing chamber 20, the liquid outlets of the other centrifugal processing chambers 20 are sealed by the sealing ring 5.

[0067] In other embodiments, the connection structure between the liquid outlet and the water treatment chamber 21 can be a pipe structure containing a solenoid valve, in addition to the annular port 50 containing the annular port 50.

[0068] In this embodiment, the rotation drive of the centrifuge seat 3 can be configured as follows: a central shaft 6 driven by a motor is provided inside the ring seat 2. The central shaft 6 is connected to the centrifuge seat 3 through a connecting rib, that is, the end of the connecting rib away from the central shaft 6 is connected to the outer wall of the central ring 30. Then, multiple centrifuge seats 3 rotate synchronously under the drive of the central shaft 6. In some embodiments, each centrifuge seat 3 can also be driven individually by its own motor in conjunction with a gear ring.

[0069] In some embodiments, the liquid inlet of the wastewater treatment chamber 7 is as follows: A liquid inlet is provided on the central ring 30, and a control component for opening the liquid inlet is provided at the liquid inlet. In some embodiments, the control component is a baffle structure, which is the same principle as the sealing ring 5. That is, the baffle structure can slide vertically and has an opening. When the opening is aligned with the liquid inlet, the wastewater treatment chamber 7 and the inner cavity of the ring seat 2 are connected, with the inner cavity of the ring seat 2 serving as the wastewater inlet chamber. It should be added that the baffle structure is driven vertically up and down by a vertical drive component (such as a screw, electric push rod, or cylinder, or other existing linear drive components). The vertical drive component is installed on one of the centrifuge seats 3 and is covered with a waterproof shell. Preferably, it is located on the uppermost centrifuge seat 3, and the wastewater will not overflow the vertical drive component. This arrangement allows the vertical drive component and the centrifuge seat 3 to rotate synchronously while remaining relatively stationary, avoiding motion interference caused by the baffle structure on the rotation of the connecting ribs. Alternatively, the control component can also be a pipe structure with a solenoid valve.

[0070] In this embodiment, to facilitate the flow of wastewater from the water ring vacuum pump into the ring seat 2, one end of the inlet pipe is connected to the center of the ring seat 2, and the other end is connected to the outlet of the water ring vacuum pump, allowing the wastewater from the water ring vacuum pump to flow into the ring seat 2. Furthermore, the outer diameter of the central shaft 6 is smaller than the inner diameter of the ring seat 2, causing the wastewater to flow into the gap between the central shaft 6 and the inner wall of the ring seat 2, thus facilitating the entry of wastewater into the wastewater treatment chamber 7.

[0071] It should be added that: the bottom and top of the center of the ring seat 2 are sealed, thus forming the transition cavity structure of the entire wastewater. The output end of the inlet pipe is connected to the bottom sealing plate of the center of the ring seat 2, and the outlet of the inlet pipe is located at the bottom of the ring seat 2. That is, after the wastewater enters the center of the ring seat 2, it flows vertically upward. Under the action of water flow, the wastewater is driven to flow from the bottom to the top. This avoids impurities in the wastewater from settling at the bottom of the ring seat 2, and the wastewater can flow into the wastewater treatment chamber 7 in the bottom-up flow mode.

[0072] It should be added that: the impurity collection chamber 22 can be connected to the inner cavity of the ring seat 2 via a discharge pipe containing a control valve. When the discharge pipe is open and the centrifuge chamber 20 is closed, the impurities stored in the impurity collection chamber 22 flow to the inner cavity of the ring seat 2 through water flushing or other means. The top sealing plate at the center of the ring seat 2 has an impurity outlet. When this impurity outlet is opened, the water flowing in from the water inlet pipe causes the impurities in the inner cavity of the ring seat 2 to flow upward and out from the impurity outlet. In some other embodiments, the ring seat 2 is an assembled structure, and the centrifuge seat 3 can be removed separately, and the sealing plate on the side wall of the impurity collection chamber 22 can be opened to clean the impurities in the impurity collection chamber 22. The cleaning method of the impurity collection chamber 22 is not limited to the above two methods; any structure that facilitates the cleaning of impurities in the impurity collection chamber 22 is acceptable, as this cleaning method is not the focus of this application.

[0073] Furthermore, the water outlet pipe is connected to the top of the water treatment chamber 21 and the water inlet of the water ring vacuum pump. The purified water in the water treatment chamber 21 is guided to the water ring vacuum pump by the water outlet pipe to achieve water circulation.

[0074] In addition, a water supply pipe is connected to the water treatment chamber 21. Because water is lost during the water circulation process between the water ring vacuum pump and the wastewater processor, water is replenished into the water treatment chamber 21 through an external water supply pipe to ensure the stability of the entire circulating water volume. The water supply pipe draws water from the external water storage structure.

[0075] Finally, it is necessary to add the wastewater treatment process in wastewater treatment chamber 7, the specific process is as follows:

[0076] Flocculant is added to the wastewater treatment chamber 7 through an external flocculant delivery pipe. Then, the central shaft 6 rotates alternately in both directions under the drive of a motor for 3-5 minutes, so that the wastewater and flocculant in the wastewater treatment chamber 7 can fully contact each other, and the impurities in the wastewater are suspended. Then, the central shaft 6 rotates unidirectionally for 3-5 minutes under the drive of a motor, specifically, it rotates in the direction of the dust collection protrusion 32. The wastewater in the wastewater treatment chamber 7 moves towards the side wall of the isolation seat 31 containing the dust collection protrusion 32 under the action of centrifugal force, and moves radially outward along the side wall of the isolation seat 31. The suspended matter in the wastewater is collected in multiple dust collection tanks 320. With the rotation of the centrifugal seat 3, the suspended matter in the dust collection tank 320 can be guided to the impurity collection chamber 22 by the continuously moving impurity removal rod 4.

[0077] It should be added that: in order to ensure that the flocculant and wastewater are fully mixed, the isolation seat 31 is provided with multiple guide protrusions 33 on the side away from the dust collection protrusion 32. The guide protrusions 33 include guide slopes, which are set towards the dust collection protrusion 32. That is, during the forward and reverse rotation of the centrifugal seat 3, under the action of centrifugal force, the guide slopes of the guide protrusions 33 guide the mixture to the center of the wastewater treatment chamber 7, thereby achieving full contact of the mixture in the wastewater treatment chamber 7.

[0078] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0079] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
