Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically to an industrial circulating water pump with descaling function. Background Technology

[0002] Industrial circulating water pumps are the main conveying tools for industrial water circulation. They are generally fluoropolymer-lined centrifugal pumps, which have excellent corrosion resistance and high temperature resistance.

[0003] Most industrial circulating water pumps currently on the market are similar in overall structure. They use a drive motor to drive a shaft in the shaft housing to rotate at high speed, and the impeller at the end of the shaft rotates at high speed, drawing industrial water from the medium inlet and pumping it out from the medium outlet. However, in actual use, they have some functional shortcomings and room for improvement. For example, in continuous conveying operations, if the calcium content of the industrial circulating water is high, scale is easily formed inside the impeller and pump casing, increasing power consumption and reducing conveying efficiency. Cleaning requires separating the pipeline and pump, and then disassembling the pump casing for descaling, which is cumbersome and time-consuming, affecting production efficiency and lacking a convenient descaling function.

[0004] Now, a novel industrial circulating water pump with descaling function is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an industrial circulating water pump with descaling function to solve the problem mentioned in the background art of not having a convenient descaling function.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an industrial circulating water pump with descaling function, comprising a bottom support frame, a drive motor mounted on the right side of the top of the bottom support frame, a pump casing fixedly connected to the left side of the top of the bottom support frame, a shaft seat provided on the right side of the pump casing, an impeller movably connected inside the pump casing, a medium outlet fixedly connected to the rear end of the pump casing, a medium inlet fixedly connected to the middle position of the left side of the pump casing, and a cleaning component for easy removal of scale from the pump interior provided at the bottom of the bottom support frame.

[0007] The cleaning assembly includes a transfer box, which is fixedly connected to the right side of the bottom end of the bottom support frame. The transfer box has an outlet on its left side and an inlet on its right side. A circulation pump is installed on the left side of the transfer box. A controller is fixedly connected to the left side of the bottom end of the bottom support frame. A drain port is fixedly connected to the bottom of the pump housing. An inlet port is fixedly connected to the top of the front end of the media outlet. A first solenoid valve is installed at the bottom of the inlet port. An inlet pipe is fixedly connected between the first solenoid valve and the circulation pump. A first sealing valve is installed at the top of the media outlet, and a second sealing valve is installed on the left side of the media inlet.

[0008] As a further technical solution of this utility model, the media outlet and the liquid inlet are internally connected, and the pump casing and the sewage outlet are internally connected.

[0009] As a further technical solution of this utility model, the circulating pump and the liquid outlet are connected, and the liquid outlet, the transfer box and the liquid inlet are internally connected.

[0010] As a further technical solution of this utility model, the first sealing valve and the second sealing valve have the same specifications, and the first sealing valve, the second sealing valve, the first solenoid valve, the controller, and the circulating pump are electrically connected.

[0011] As a further technical solution of this utility model, internal thread mounting seats are welded to the upper and lower ends of the left side of the pump casing, and an ultrasonic transducer is threaded to the left side of the internal thread mounting seat. The right side of the ultrasonic transducer is tightly fitted to the pump casing, and the internal thread mounting seats are symmetrically distributed about the horizontal center line of the impeller.

[0012] As a further technical solution of this utility model, a drain pipe is provided below the drain port, a second solenoid valve is installed between the drain port and the drain pipe, the inlet pipe and the drain pipe have the same diameter, and the controller and the second solenoid valve are electrically connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the industrial circulating water pump with descaling function not only realizes the function of easy descaling, but also realizes the function of accelerating scale removal, and also realizes the function of easy sewage discharge.

[0014] (1) By setting a first sealing valve, a second sealing valve, an inlet port, a first solenoid valve, an inlet pipe, a drain port, a controller, a circulating pump, an outlet, a transfer box and an inlet port, when in use, the drive motor drives the shaft in the shaft seat to rotate continuously, and the shaft drives the impeller to rotate at high speed, sucking in industrial circulating water from the medium inlet and pumping it out from the medium outlet. When it is necessary to clean the scale inside the pump casing, first close the second sealing valve, open the first solenoid valve and the circulating pump, and the circulating pump pumps the agent inside the transfer box into the pump casing through the inlet pipe. The drain port simultaneously discharges the industrial circulating water remaining inside the pump casing. As the pump casing is filled with agent, the first sealing valve, the first solenoid valve and the second solenoid valve are closed, and the drive motor is started to make the impeller rotate at high speed, promoting the flow of agent inside the pump casing and accelerating the dissolution of scale. There is no need to disassemble the pipe and the pump, which realizes the function of easy scale removal.

[0015] (2) By setting an internal thread mounting base and an ultrasonic transducer, during use, an external ultrasonic generator is connected to the ultrasonic transducer during the scale dissolution process. The ultrasonic waves emitted by the ultrasonic transducer on the internal thread mounting base diffuse continuously inside the pump casing with the agent as the medium, accelerating the peeling of scale and realizing the function of accelerating scale removal.

[0016] (3) By setting a second solenoid valve and a drain pipe, when in use, after dissolving scale for a period of time, the first solenoid valve and the second solenoid valve open simultaneously and inject clean water into the transfer box through the liquid inlet. The circulating pump pumps the clean water into the pump casing, squeezing out the scale, chemicals, etc. inside. The chemicals containing scale are discharged outward along the drain pipe, thus realizing the function of easy sewage discharge. Attached Figure Description

[0024] Please see Figure 1-4 An industrial circulating water pump with descaling function also includes a cleaning component, which includes a transfer box 17. The transfer box 17 is fixedly connected to the right side of the bottom end of the bottom support frame 1. An outlet 16 is provided on the left side of the transfer box 17, an inlet 18 is provided on the right side of the transfer box 17, and a circulating pump 15 is installed on the left side of the transfer box 17.

An inlet port 10 is fixedly connected to the top of the front end of the medium outlet 6. A first solenoid valve 11 is installed at the bottom end of the inlet port 10. An inlet pipe 12 is fixedly connected between the first solenoid valve 11 and the circulating pump 15. A first sealing valve 8 is installed at the top of the medium outlet 6, and a second sealing valve 9 is installed on the left side of the medium inlet 7.

[0025] The media outlet 6 and the liquid inlet 10 are internally connected; the pump casing 4 and the drain outlet 13 are internally connected; the circulating pump 15 and the liquid outlet 16 are connected; the liquid outlet 16, the transfer box 17, and the liquid inlet 18 are internally connected; the first sealing valve 8 and the second sealing valve 9 have the same specifications; the first sealing valve 8, the second sealing valve 9, the first solenoid valve 11, the controller 14, and the circulating pump 15 are electrically connected to facilitate rapid descaling.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, first close the second sealing valve 9, open the first solenoid valve 11 and the circulation pump 15. The circulation pump 15 pumps the agent inside the transfer box 17 into the pump casing 4 through the inlet pipe 12. The drain port 13 simultaneously discharges the residual industrial circulating water inside the pump casing 4. As the pump casing 4 is filled with the agent, the first sealing valve 8, the first solenoid valve 11, and the second solenoid valve 21 are closed. The drive motor 2 is started to make the impeller 5 rotate at high speed, which promotes the flow of the agent inside the pump casing 4 and accelerates the dissolution of scale. The first sealing valve 8, the second sealing valve 9, the first solenoid valve 11, the controller 14, and the circulation pump 15 are electrically connected. This technology is existing technology and will not be described in detail.

[0027] Internal thread mounting seats 19 are welded to the upper and lower ends of the left side of the pump casing 4. An ultrasonic transducer 20 is threaded to the left side of the internal thread mounting seat 19. The right side of the ultrasonic transducer 20 is tightly fitted to the pump casing 4. The internal thread mounting seats 19 are symmetrically distributed about the horizontal center line of the impeller 5 to accelerate the removal of scale.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the ultrasonic generator is connected to the ultrasonic transducer 20. The ultrasonic waves emitted by the ultrasonic transducer 20 on the internal thread mounting base 19 diffuse continuously inside the pump casing 4 with the reagent as the medium, accelerating the peeling of scale.

[0029] A drain pipe 22 is provided below the drain port 13. A second solenoid valve 21 is installed between the drain port 13 and the drain pipe 22.

The circulation pump 15 pumps the clean water into the pump casing 4, squeezing out the scale, chemicals, etc. inside. The chemicals containing scale are discharged outward along the drain pipe 22. The controller 14 and the second solenoid valve 21 are electrically connected. This technology is existing technology, so it will not be described in detail.

[0031] Working Principle: In use, the drive motor 2 first drives the shaft inside the shaft seat 3 to rotate continuously. The shaft drives the impeller 5 to rotate at high speed, drawing industrial circulating water from the medium inlet 7 and pumping it out from the medium outlet 6. When cleaning scale inside the pump casing 4, the second sealing valve 9 is closed, and the first solenoid valve 11 and the circulation pump 15 are opened. The circulation pump 15 pumps the reagent inside the transfer box 17 into the pump casing 4 through the inlet pipe 12. Simultaneously, the drain port 13 discharges the residual industrial circulating water inside the pump casing 4. As the pump casing 4 is filled with reagent, the first sealing valve 8, the first solenoid valve 11, and the second solenoid valve 21 are closed. The drive motor 2 is then started, causing the impeller 5 to rotate at high speed, promoting the flow of reagent inside the pump casing 4 and accelerating the dissolution of scale. During the scale dissolution process, an external ultrasonic generator is connected to the ultrasonic transducer 20. The ultrasonic waves emitted by the ultrasonic transducer 20 on the internal thread mounting seat 19 diffuse continuously inside the pump casing 4 using the reagent as a medium, accelerating the removal of scale. After the scale has been dissolved for a period of time, the first solenoid valve 11 and the second solenoid valve 21 open simultaneously and inject clean water into the transfer box 17 through the liquid inlet 18. The circulation pump 15 pumps the clean water into the pump casing 4, squeezing out the scale, chemicals, etc. inside. The chemicals containing scale are discharged outward along the drain pipe 22.
