Description

Technical Field

[0002] Magnetic pumps are used to transport liquids. Their working principle is to transport liquids through the attraction and discharge of magnetic fields. The flow-through parts of fluoroplastic magnetic pumps are made of metal inlaid with fluoroplastics. They have good corrosion resistance when transporting corrosive solutions.

[0003] When a conventional magnetic pump is conveying a solution, since the solution outlet is at the top, solution will remain under the pump body during and after the solution is conveyed. If it is a corrosive solution, it needs to be cleaned in time to prevent long-term residue from damaging the magnetic pump. In addition, during the operation of the magnetic pump, the drive motor is mostly equipped with a heat dissipation mechanism, and the isolation sleeve inside the magnetic pump will also generate heat during the transmission of magnetic torque and friction. If it is not operated, the isolation sleeve may be deformed over time, affecting the operation of the magnetic pump. Summary of the invention

[0004] The object of the present invention is to provide a fluoroplastic magnetic pump with corrosion resistance to solve the problems in the prior art.

[0007] In the fluoroplastic magnetic pump, the magnetic pump is used to transport liquids. The liquid transportation is achieved through the attraction and stone removal of the magnetic field. The fluoroplastic contained in it can resist corrosion well and will not cause damage to the magnetic pump due to the transportation of corrosive solutions. The recoil mechanism is arranged inside the pump body. During the solution transportation process, the solution at a lower position may remain in the corners inside the pump body. Through the recoil mechanism, the solution is flushed in the opposite direction during the transportation process, so that the solution can better follow the overall trend of the solution and flow out from the outlet. The temperature detection mechanism is used to detect the heat-prone parts inside the pump body. Through the detection, the motor and the input solution amount are adjusted in real time to prevent the temperature from being too high.

[0009] In the pump body, all mechanisms are placed on the base. When the first drive motor is started, the outer magnetic rotor begins to rotate, generating a rotating magnetic field, which interacts with the inner magnetic rotor to generate a magnetic coupling driving force. Due to the interaction of magnetic forces, magnetic coupling is formed between the outer magnetic rotor and the inner magnetic rotor, and the inner magnetic rotor and impeller are connected to the pump shaft. Therefore, the impeller can be driven to rotate through the action of the magnetic field, and the solution is transported from the water inlet to the water outlet through centrifugal force, thereby completing the delivery of the solution.

[0010] The recoil mechanism comprises a driving device, which is connected to a pump housing and is placed in a pump cavity. The driving device comprises a driving chamber, a servo motor and a driving disk. The driving chamber is placed in the pump cavity, a driving cavity is arranged in the driving chamber, the servo motor is connected to the driving chamber, the servo motor is placed in the driving cavity, a fixed end of the servo motor is tightly connected to a wall surface of the driving cavity, a first through hole and a second through hole are arranged on the driving disk, the first through hole is placed in the middle of the driving disk, the second through hole is placed on one side of the first through hole, a distance from the first through hole to the second through hole is smaller than a radius of the driving disk, the driving disk is connected to the driving chamber, the driving disk is placed in the driving cavity, the driving disk is connected to the servo motor, and the servo motor output The outlet end is tightly connected to the first through hole, the recoil mechanism also includes a recoil device, the recoil device includes a recoil chamber, a recoil baffle and a connecting rod, the recoil device is connected to the driving device, the recoil device is connected to the driving chamber, the recoil device is placed in the driving cavity, the connecting rod is connected to the driving disk, one end of the connecting rod is rotatably connected to the second through hole, the recoil chamber is tightly connected to the wall of the driving cavity, a recoil baffle is arranged in the recoil chamber, a circular opening is arranged on the top of the recoil chamber, the connecting rod is slidably connected to the circular opening of the recoil chamber, one end of the connecting rod away from the second through hole is tightly connected to the recoil baffle, the recoil chamber is opened away from one end of the connecting rod, and the opening of the recoil chamber faces the direction of solution inflow.

[0011] In the recoil mechanism, a force opposite to the flow direction of the solution is given to the solution at the bottom of the pump housing through the recoil mechanism, so that the solution at the bottom has a force in the opposite direction, and can better flow out of the pump body together with most of the solution under the action of the magnetic pump, thereby reducing the residual solution in the pump body and reducing the damage of the corrosive solution to the pump body. By setting a driving device, the recoil device is driven to recoil the solution, the servo motor is placed in the driving cavity, and the output end is tightly connected to the driving disk. After the servo motor is started, it can rotate with the driving disk. There is a second through hole on the driving disk, and the driving disk is rotatably connected to the connecting rod through the second through hole. , and the straight line where the servo motor output end is located is perpendicular to the straight line where the connecting rod is located, the other end of the connecting rod is tightly connected to the recoil baffle, and the recoil baffle is slidably connected to the inner wall of the recoil chamber. Therefore, when the servo motor drives the driving disk to rotate, the driving disk will move with the connecting rod, and the connecting rod and the recoil baffle are tightly connected, so the recoil baffle will slide back and forth along the wall surface of the recoil chamber. When the opening end of the recoil chamber slides behind the recoil baffle, the solution will enter the opening end, and when the recoil baffle slides forward, the solution is pushed out. Through such recoil, the solution can flow out better and reduce the residue in the pump body.

[0012] The temperature detection mechanism includes a detection device, the detection device is connected to the main device, the detection device is connected to the isolation sleeve, the detection device includes a thermocouple and a ceramic ring, the isolation sleeve is provided with an annular groove, the ceramic ring and the annular groove of the isolation sleeve are tightly connected, the thermocouple and the ceramic ring are tightly connected, the temperature detection mechanism also includes a feedback device, the feedback device is tightly connected to the base, the feedback device is connected to the pump housing, the feedback device is connected to the water inlet pipe, the feedback device includes a second drive motor, a drive ring, an arc-shaped baffle, a rotating rod and a baffle, the baffle is tightly connected to the water inlet pipe, the drive ring and the water inlet pipe Rotational connection, a plurality of fixed blocks are arranged on the baffle plate, a gear is arranged on the outer ring of the driving ring, a gear groove is arranged on the water inlet pipe, the driving ring gear passes through the gear groove of the water inlet pipe, the output end of the second driving motor is meshed with the driving ring gear, the fixed end of the second driving motor is tightly connected to the base, a plurality of rotational grooves are arranged on the driving ring, the number of the rotating rod, the arc-shaped baffle plate, the fixed block and the rotational groove are consistent, the baffle plate fixing block and the driving ring rotational groove are slidingly connected, one end of the rotating rod is rotationally connected to the driving ring, the other end of the rotating rod is rotationally connected to the arc-shaped baffle plate, and the arc-shaped baffle plate and the baffle plate are rotationally connected through the rotating shaft.

[0013] In the temperature detection mechanism, the mechanism is used to detect the surface temperature of the isolation sleeve. During the operation of the magnetic pump, the isolation sleeve is a key component in the magnetic pump. It is located between the inner magnetic rotor and the outer magnetic rotor and plays the role of transmitting the magnetic torque. In the process of transmitting the magnetic torque, the isolation sleeve will generate a certain amount of heat and will also withstand the pressure and temperature of the medium. Friction will occur between the isolation sleeve and the inner magnetic rotor, the outer magnetic rotor and some other components, which will also generate heat, causing the temperature of the isolation sleeve to rise. In the long run, the isolation sleeve material may be deformed, which will affect the use of the magnetic pump. By setting a detection device, a part of the isolation sleeve is wrapped by a ceramic ring to prevent the thermocouple from affecting the magnetic torque transmission during operation. At the same time, the ceramic ring has good thermal conductivity and can well transmit the temperature of the isolation sleeve. If the detected temperature is high, the first drive motor reduces the drive, the torque transmission is reduced, and the second drive motor is started to rotate the drive ring, and the arc-shaped baffle gathers toward the middle of the drive ring. The flow entering the pump body is reduced by reducing the aperture of the water inlet pipe, so that the isolation sleeve can be naturally cooled.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: after the present invention is started, the magnetic pump is used to transport the fluid. The magnetic pump is made of fluoroplastic material, which has good corrosion resistance and can support the transportation of corrosive solutions. In the present invention, a recoil mechanism is arranged in the pump casing. After the solution enters the pump body, the servo motor is started to drive the drive disk to rotate, and the connecting rod and the recoil baffle are tightly connected, so the recoil baffle will slide back and forth along the inner wall of the recoil chamber. When the opening end of the recoil chamber slides behind the recoil baffle, the solution will enter the opening end. When the recoil baffle slides forward, the solution is pushed out. Through such recoil, The solution flows out better and reduces the residue in the pump body. Then, a temperature detection mechanism is set to detect the surface temperature of the isolation sleeve. The ceramic ring is wrapped around the isolation sleeve to prevent the thermocouple from affecting the magnetic torque transmission during operation. At the same time, the ceramic ring has good thermal conductivity and can transmit the temperature of the isolation sleeve very well. If the detected temperature is high, the first drive motor reduces the drive, the torque transmission is reduced, and the second drive motor is started to rotate the drive ring. The arc-shaped baffle gathers toward the middle of the drive ring, and the flow rate entering the pump body is reduced by reducing the aperture of the water inlet pipe, so that the isolation sleeve can cool down naturally, ensuring that the magnetic pump can operate for a long time and extending its service life.
