Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic pumps, and particularly relates to an anti-blocking magnetic pump. Background Art

[0002] The magnetic pump is a leak-free fluid conveying device based on the principle of magnetic transmission. It uses the magnetic lines of force generated by permanent magnets to transmit the rotational torque of the motor to the impeller inside the pump body without contact through magnetic coupling, thereby driving the flow of the medium. The main structure of the magnetic pump includes the pump body, magnetic transmission device, motor and other parts, among which the magnetic transmission device consists of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. During operation, the motor drives the outer magnetic rotor to rotate through the coupling, and the magnetic lines of force are transmitted through the air gap and the non-magnetic isolation sleeve, so that the inner magnetic rotor rotates synchronously with the impeller to achieve the purpose of contactless transmission of torque. Since the magnetic pump adopts a contactless magnetic transmission method, it completely solves the problem of shaft seal leakage in traditional pumps. It has the advantages of full sealing, no leakage, and no pollution. It is widely used in chemical, environmental protection, medicine, petroleum, electricity and other fields.

[0003] Publication No. "CN221003153U" is an anti-clogging magnetic pump, comprising a magnetic pump, a base is fixedly installed at the bottom of the magnetic pump, one end of the magnetic pump is fixedly connected to a liquid outlet pipe, the upper side of the outer end of the magnetic pump is fixedly connected to a liquid inlet pipe, an anti-clogging mechanism is arranged inside the liquid inlet pipe, an external pipe is fixedly installed on the upper end of the liquid inlet pipe, and a sealing mechanism is arranged inside the liquid inlet pipe. The utility model uses the action of a spring to ensure that the sealing block is always connected to the external pipe, thereby increasing the sealing effect of the connection, and preliminarily filters the liquid entering the external pipe through the mesh plate, and filters any larger debris that may appear. When the liquid flows out of the connecting pipe, the liquid flow drives the blades to rotate, and the rotating rod drives the scraper to rotate, so that the debris on the surfaces of the first filter plate, the second filter plate and the third filter plate are temporarily cleaned, so that the debris no longer accumulates, the device no longer gets blocked, and the long-term safe operation of the magnetic pump is improved.

[0004] Although the utility model enables the rotating rod to drive the scraper to rotate, and briefly cleans the debris on the surface of the filter plate 1, the filter plate 2 and the filter plate 3, so that the debris does not accumulate, the device does not get blocked, and the long-term safe operation of the magnetic pump is improved, but if the debris on the filter plate is not cleaned in time, and only relies on the scraper to briefly clean the surface of the filter plate to prevent the debris from accumulating, when too much debris accumulates on the surface of the filter plate, the magnetic pump will still get blocked, which is very inconvenient. Utility Model Content

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions:

[0007] An anti-blocking magnetic pump includes a magnetic pump body.

A first filter plate is threadedly connected to the bottom end of the filter chamber. A second filter plate is installed inside the filter chamber. An outer connecting pipe is installed inside the water inlet pipe. The upper end of the outer connecting pipe is fixedly connected with a second flange. Fixing plates are symmetrically and fixedly connected to the outer side wall of the water inlet pipe. Fixing blocks are symmetrically and fixedly connected to the outer side wall of the outer connecting pipe. A fixing component is installed on the upper end of the fixing plate, which can effectively prevent solid particles, impurities, etc. from entering the pump body and protect the normal operation of the magnetic pump.

[0008] The fixing component includes a cavity, a return spring, a moving plate, a locking block and an inclined surface. A connecting block is fixedly connected to the upper end of the fixing plate. Cavities are symmetrically opened inside the connecting block. One end inside the cavity is fixedly connected with a return spring, and the other end of the return spring is fixedly connected with a moving plate. The moving plate is slidably connected to the cavity. A locking block is fixedly connected to the end of the moving plate away from the return spring.

A connecting groove is opened at the bottom end of the fixing block. The connecting groove is inserted into the connecting block. Locking grooves are symmetrically opened at one end inside the connecting groove. The locking grooves penetrate through the fixing block. Unlocking blocks are slidably connected inside the locking grooves. The ends of the unlocking blocks away from the locking block extend out of the side end of the fixing block. Limiting blocks are symmetrically and fixedly connected to both ends of the unlocking blocks. Limiting grooves are symmetrically opened inside the locking grooves. The limiting grooves are slidably connected to the limiting blocks, which facilitates the regular cleaning of the surface of the filter plate, can effectively prevent the accumulation of impurities and particles, thereby preventing blockage, ensuring that the magnetic pump operates in the best state, and thus improving the efficiency of the equipment.

[0009] As a preferred technical solution, positioning holes are symmetrically opened at the upper end of the fixed frame through a circumferential array. Positioning columns are symmetrically and fixedly connected to the bottom end of the installation frame through a circumferential array.

Sliding blocks are symmetrically and fixedly connected to the outer side wall of the installation frame and the outer side wall of the outer connecting pipe. The sliding blocks are slidably connected to the sliding grooves, which can enable both the filter chamber and the outer connecting pipe to be accurately installed inside the water inlet pipe, ensuring the accuracy and stability of the installation.

[0010] As an optimal technical solution, a sealing gasket is fixedly connected to the outer wall of the external tube, the bottom end of the external tube abuts against the upper end of the mounting frame, and the external tube is plugged into the inside of the water inlet pipe to ensure that the magnetic pump will not leak during operation, thereby ensuring the sealing and safety of the magnetic pump.

[0012] First, in the utility model, the external water pipe is inserted into the water inlet pipe, and the slider slides inside the slide groove, and the connecting block is inserted into the connecting groove. During the insertion process, the extrusion force exerts pressure on the inclined surface of the upper end of the locking block, so that the locking block drives the moving plate to compress the reset spring, and the locking block retracts into the cavity. Then, when the locking block moves to the locking groove, the reset spring resets, and the moving plate rebounds to drive the locking block to pop out. The locking block and the locking groove are clamped and fixed. At the same time, the bottom end of the external pipe is abutted against the upper end of the installation frame to complete the installation of the external pipe, which is convenient for users to quickly install and disassemble the external pipe, thereby facilitating regular cleaning of the surface of the filter plate, which can effectively prevent the accumulation of impurities and particles, thereby preventing clogging, ensuring that the magnetic pump operates in the best state, and thus improving the efficiency of the equipment;

[0013] Second, in the utility model, the liquid entering the external pipe is firstly filtered through the second filter plate to filter out larger impurities, and then the liquid continues to be filtered through the first filter plate for secondary filtration to filter out smaller impurities. By pushing the unlocking block, the external pipe is removed from the inside of the water inlet pipe, and the filter bin is taken out upwards to make the slider slide inside the slide groove, and at the same time, the positioning column and the positioning hole are plugged in, and then the filter bin is taken out from the inside of the water inlet pipe, and the impurities on the first filter plate and the second filter plate inside the filter bin are cleaned. After cleaning, the installation of the filter bin can be completed by reverse operation, which can effectively prevent solid particles, impurities, etc. from entering the pump body, protect the normal operation of the magnetic pump, prevent impurities from getting stuck in the magnetic pump rotor, reduce jamming, wear and other faults caused by impurities, and ensure the normal rotation of the magnetic pump.
