Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment devices, in particular to a vertical circulating submerged mixer. Background Art

[0002] Submersible mixers are key equipment in sewage treatment process regulating tanks. They can achieve the process requirements of homogenization and flow of solid-liquid two-phase flow in the biochemical process of sewage in the regulating tank. They are suitable for solid-liquid mixing occasions. The stirring of submersible mixers can prevent the precipitation and stratification of suspended matter. In the process of sewage treatment using activated sludge method, the activated sludge is continuously stirred by the mixer to make the anaerobic microorganisms and the matrix fully contact, thereby improving the treatment effect.

[0003] After searching the publication (announcement) number: CN200948415Y, a vertical circulation submersible mixer is disclosed. It includes a motor, an impeller matched with the motor, a guide cylinder covered outside the impeller, and a circulation distributor arranged at the water outlet end of the guide cylinder. It is characterized in that the impeller is directly connected to the motor shaft, and a trash rack is arranged between the guide cylinder and the motor. This utility model changes the existing motor-mounted mixer into a motor-mounted mixer, and has the following substantial characteristics: 1. The impeller is directly connected to the shaft of the submersible motor, which shortens the distance of the transmission relationship between each other, ensures reliable transmission, and saves energy; 2. The installation method can be selected according to the actual situation, with a wide range of applications and convenient use; 3. There are few parts, a simple structure, and convenient installation and maintenance, which reduces the production and processing costs and increases the service life.

[0004] Although the above scheme keeps the sludge in the pool in a tumbling and suspended state, increases the contact area between the physical phase and the gas phase, and improves the treatment effect, part of the tumbling sludge will adhere to the trash rack. The sludge that is not cleaned in time will be deposited on the trash rack to form large pieces of dirt, which will hinder the sewage from entering the trash rack and reduce the impeller's treatment efficiency of the sewage. For this reason, we propose a vertical circulating submersible mixer. Utility Model Content

[0005] The main purpose of the utility model is to provide a vertical circulating submerged mixer, which solves the problem that part of the tumbling sludge will adhere to the trash rack through the main unit and the cleaning unit. The sludge that cannot be cleaned in time will be deposited on the trash rack to form large pieces of dirt, which will hinder the sewage from entering the trash rack and reduce the impeller's treatment efficiency of the sewage.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A vertical circulating submersible mixer, comprising a main body unit, characterized in that it further comprises a cleaning unit arranged on the surface of the main body unit, a water outlet unit arranged below the main body unit, and a mounting unit arranged above the main body unit;

[0008] The main body unit includes a submersible motor, a guide cylinder arranged below the submersible motor, a trash rack arranged between the submersible motor and the guide cylinder, and a stirring member arranged inside the trash rack;

[0009] The cleaning unit includes a C-shaped seat mounted on the surface of the main body unit, a threaded shaft movably arranged in the C-shaped seat, a driving motor mounted at the input end of the threaded shaft, a connecting member arranged on the threaded shaft, and a cleaning member arranged at the top of the connecting member.

[0010] Preferably, the stirring member includes a movable shaft mounted at the output end of the submersible motor, and an impeller mounted on the side wall of the movable shaft.

[0011] Preferably, the connecting member includes a moving member mounted on the circumferential side surface of the threaded shaft, and a connecting rod mounted on the side wall of the moving member.

[0012] Preferably, the cleaning member includes an annular seat mounted on the top of the connecting rod, and a cleaning soft brush mounted on the inner side wall of the annular seat.

[0013] Preferably, the cleaning unit further includes a limit washer mounted on the inner side wall of the C-shaped seat, and the limit washer is sleeved on the circumferential side surface of the threaded shaft.

[0014] Preferably, the water outlet unit includes a circulation distributor mounted at the bottom of the guide cylinder, and a water outlet opening formed on the side wall of the circulation distributor.

[0015] Preferably, the mounting unit includes a mounting pipe mounted on the top of the submersible motor, and a floating cylinder mounted on the top of the mounting pipe.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the present utility model, through the arranged main body unit and cleaning unit, after the mixer works for a period of time, the driving motor drives the threaded shaft to rotate. At this time, the connecting piece drives the cleaning piece to move along the threaded shaft, so that the cleaning soft brush cleans and removes the sludge on the trash rack, thus avoiding the deposition of sludge on the trash rack to form large dirt, providing a guarantee for the normal entry of sewage into the interior of the trash rack, and further improving the sewage treatment effect. When sewage treatment is carried out, the submersible motor drives the propulsion impeller to work, causing the fluid to generate a certain flow rate, spraying and diffusing around at a certain angle at the bottom of the pool to form an annular main flow zone. The guide cylinder introduces air to form a gas-liquid mixed phase with the flowing water. Because the flow rate of the main flow zone is relatively large, a turbulent flow region centered on it is formed around it, promoting the water in the whole pool to form a large cycle of up and down turning, so as to realize large-area three-dimensional circulation stirring, making the sludge in the pool always in a turning and suspended state, increasing the contact surface between the solid phase and the gas phase, eliminating the stirring dead angle, achieving the purpose of uniform and gentle stirring, ensuring a good aerobic treatment effect, and improving the treatment efficiency.

[0031] As Figure 2 shown, the main body unit 1 includes a submersible motor 101, a guide cylinder 102 arranged below the submersible motor 101, a trash rack 104 arranged between the submersible motor 101 and the guide cylinder 102, and a stirring member 103 arranged inside the trash rack 104. When the submersible motor 101 drives the stirring member 103 to rotate, the sewage in the trash rack 104 can be stirred;

[0032] As Figure 3 shown, the cleaning unit 2 includes a C-shaped seat 201 installed on the surface of the main body unit 1, a threaded shaft 202 movably arranged in the C-shaped seat 201, a driving motor 203 installed at the input end of the threaded shaft 202, a connecting member 204 arranged on the threaded shaft 202, and a cleaning member 205 arranged at the top of the connecting member 204. When the driving motor 203 drives the threaded shaft 202 to rotate, the connecting member 204 drives the cleaning member 205 to move up and down along the threaded shaft 202.

[0032] As Figure 3 shown, the stirring member 103 includes a movable shaft 1031 installed at the output end of the submersible motor 101, and an impeller 1032 installed on the side wall of the movable shaft 1031. When the submersible motor 101 drives the movable shaft 1031 to rotate, the impeller 1032 can be driven to rotate synchronously.

[0033] As Figure 3 shown, the connecting member 204 includes a moving member 2041 installed on the circumferential side surface of the threaded shaft 202, and a connecting rod 2042 installed on the side wall of the moving member 2041. When the threaded shaft 202 rotates, the moving member 2041 can drive the connecting rod 2042 to move synchronously.

When the connecting rod 2042 moves up and down, the annular seat 2051 can drive the cleaning soft brush 2052 to clean the trash rack 104.

[0035] like Figure 1 As shown, the water outlet unit 3 includes a circulation distributor 301 installed at the bottom of the guide cylinder 102, and a water outlet 302 opened on the side wall of the circulation distributor 301. The setting of the water outlet 302 can better distribute the water in the circulation distributor 301 to flow out.

[0036] like Figure 3 As shown, the installation unit 4 includes a mounting pipe 401 installed on the top of the submersible motor 101, and a buoy 402 installed on the top of the mounting pipe 401. The buoyancy of the buoy 402 limits the mixer to a certain position in the water.

[0037] After the mixer has been working for a period of time, the driving motor 203 drives the threaded shaft 202 to rotate. At this time, the connecting piece 204 drives the cleaning piece 205 to move along the threaded shaft 202, so that the cleaning soft brush 2052 cleans and removes the sludge on the trash rack 104, thereby avoiding the sludge from being deposited on the trash rack 104 to form large pieces of dirt, providing a guarantee for the sewage to enter the trash rack 104 normally, thereby improving the sewage treatment effect. Example

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, a vertical circulating submerged mixer comprises a main unit 1, a cleaning unit 2 arranged on the surface of the main unit 1, a water outlet unit 3 arranged below the main unit 1, and a mounting unit 4 arranged above the main unit 1;

[0039] like Figure 1 As shown, the main unit 1 includes a submersible motor 101, a guide cylinder 102 disposed below the submersible motor 101, a trash rack 104 disposed between the submersible motor 101 and the guide cylinder 102, and a stirring member 103 disposed inside the trash rack 104. When the submersible motor 101 drives the stirring member 103 to rotate, the sewage in the trash rack 104 can be stirred;

[0040] like Figure 2As shown in the figure, the cleaning unit 2 includes a U-shaped seat 201 installed on the surface of the main body unit 1, a threaded shaft 202 movably arranged in the U-shaped seat 201, a drive motor 203 installed at the input end of the threaded shaft 202, a connecting member 204 arranged on the threaded shaft 202, and a cleaning member 205 arranged on the top of the connecting member 204. The drive motor 203 drives the threaded shaft 202 to rotate, and the connecting member 204 drives the cleaning member 205 to move up and down along the threaded shaft 202.

[0041] As Figure 3 shown in the figure, the stirring member 103 includes a movable shaft 1031 installed at the output end of the submersible motor 101, and an impeller 1032 installed on the side wall of the movable shaft 1031. When the submersible motor 101 drives the movable shaft 1031 to rotate, the impeller 1032 can be driven to rotate synchronously.

[0042] As Figure 3 shown in the figure, the connecting member 204 includes a moving member 2041 installed on the circumferential side surface of the threaded shaft 202, and a connecting rod 2042 installed on the side wall of the moving member 2041. When the threaded shaft 202 rotates, the moving member 2041 can drive the connecting rod 2042 to move synchronously.

[0043] As Figure 5 shown in the figure, the cleaning member 205 includes an annular seat 2051 installed on the top of the connecting rod 2042, and a cleaning soft brush 2052 installed on the inner side wall of the annular seat 2051. When the connecting rod 2042 moves up and down, the annular seat 2051 can drive the cleaning soft brush 2052 to clean the trash rack 104.

[0044] As Figure 4 shown in the figure, the cleaning unit 2 further includes a limit washer 206 installed on the inner side wall of the U-shaped seat 201, and the limit washer 206 is sleeved on the circumferential side surface of the threaded shaft 202. The setting of the limit washer 206 prevents the moving member 2041 from coming into contact and collision with the inner side wall of the U-shaped seat 201 when moving along the threaded shaft 202.

[0045] As Figure 1 shown in the figure, the water outlet unit 3 includes a circulation distributor 301 installed at the bottom of the guide cylinder 102, and a water outlet 302 opened on the side wall of the circulation distributor 301. The setting of the water outlet 302 can better distribute and flow out the water in the circulation distributor 301.

[0046] As Figure 3 shown in the figure, the installation unit 4 includes an installation pipe 401 installed on the top of the submersible motor 101, and a floating cylinder 402 installed on the top of the installation pipe 401. The buoyancy of the floating cylinder 402 confines the mixer to a certain position in the water.

[0047] When sewage treatment is being carried out, the submersible motor 101 drives the propulsion impeller 1032 to work, so that the fluid has a certain flow rate, and is sprayed and diffused around at a certain angle at the bottom of the pool to form an annular mainstream belt. The guide cylinder 102 is introduced with air to form a gas-liquid mixed phase with the flowing water. Because the flow rate of the mainstream belt is relatively large, a turbulent area with it as the center is formed around it, which prompts the water in the entire pool to form a large cycle of up and down turbulence, thereby realizing a large-area three-dimensional circulation stirring, so that the sludge in the pool is always in a state of turbulence and suspension, increasing the contact surface between the physical phase and the gas phase, eliminating the stirring dead angle, achieving the purpose of uniform and gentle stirring, ensuring a good aerobic treatment effect, and improving the treatment efficiency.
