Description

Technical Field

[0001] This utility model relates to the field of magnetic pump technology, specifically to an overheat protection dilute sulfuric acid magnetic pump. Background Technology

[0002] In chemical production and industrial applications, magnetic drive pumps are widely used for transporting corrosive liquids such as dilute sulfuric acid and hydrochloric acid due to their leak-free and corrosion-resistant characteristics. However, during prolonged operation, the electromagnetic drive components of existing magnetic drive pumps may demagnetize or be damaged due to continuous high temperatures, thus affecting the pump's service life. Furthermore, uneven liquid flow within the pump chamber during transport in existing magnetic drive pumps leads to poor heat dissipation, further exacerbating overheating problems.

[0003] Therefore, the main technical problems existing in the prior art include:

[0004] The existing drive structure of magnetic pumps is prone to demagnetization or damage under high-temperature operating conditions, which affects its service life.

[0005] During operation, the uneven flow of liquid in the pump chamber of the magnetic pump leads to reduced heat dissipation efficiency, which further exacerbates the overheating phenomenon.

[0006] During prolonged use, existing magnetic pumps may experience damage to the drive components and pump chamber structure due to liquid corrosion, reducing their service life.

[0007] In view of this, we have studied and improved the existing problems to provide an overheat protection dilute sulfuric acid magnetic pump to solve the current problems. The aim of this technology is to solve the problems and improve its practical value. Utility Model Content

[0008] The purpose of this invention is to solve the above-mentioned problems in the prior art and provide an overheat protection dilute sulfuric acid magnetic pump.

[0016] The centrifugal pump impeller is rotatably mounted inside the pump box. The centrifugal pump impeller includes an impeller disk, an axial flow propeller, and a rotor disk seat fixed to the bottom surface of the impeller disk.

[0020] In a preferred example, the heat dissipation fins are arranged in a planar spiral shape, and the agitator, through its interaction with the heat dissipation fins during rotation, causes the liquid to form turbulence within the heat dissipation base, thereby improving heat dissipation efficiency.

[0021] In a preferred embodiment, the axial flow propeller is fixed to the axial center of the impeller disk, and the liquid flows axially through the surface of the axial flow propeller during the rotation of the centrifugal pump wheel, thereby improving pumping efficiency and flow stability.

The electromagnetic coils in the electromagnetic drive disk and the permanent magnet blocks are magnetically coupled through an alternating electromagnetic field to drive the centrifugal pump wheel to achieve contactless rotation.

[0040] 1. Structure and function of the pump box

[0041] The pump box 100 is an integral structure, with an inlet 110 and a drain hole 120 on its top.

[0042] The inlet pipe 110 is tangentially arranged, which facilitates the liquid to enter the pump chamber along the tangential direction, reduces the flow resistance when entering, and improves the pumping efficiency.

[0043] The drain hole 120 is axially arranged. Under the action of the centrifugal pump impeller 300, the liquid is discharged through the drain hole 120, realizing continuous output of liquid.

[0044] The pump box 100 is fixedly connected to the heat dissipation base 200 by screws or clips to form a stable overall structure.

[0045] 2. Structure and function of the heat dissipation base

[0046] The heat dissipation base 200 is located at the bottom of the pump box 100 and is integrally formed from metal material to improve heat dissipation and structural strength.

[0047] The bottom surface of the heat dissipation base 200 is provided with a number of heat dissipation fins 210 evenly arranged along the circumference. The heat dissipation fins 210 are arranged in a planar spiral shape to increase the contact area with the outside world and improve the heat dissipation efficiency.

[0048] The top surface of the heat dissipation base 200 is provided with a heat-conducting layer that fits into the top surface of the electromagnetic drive disk 400, thereby improving heat conduction performance.

[0049] The heat dissipation base 200 and the electromagnetic drive disk 400 are fixed together by adhesive or mechanical locking to form an integrated structure.

[0050] 3. Structure and function of centrifugal pump impeller

[0051] The centrifugal pump impeller 300 is a power assembly installed inside the pump chamber, which includes:

[0052] Impeller disk 310: It has an overall disc-shaped structure and is made of corrosion-resistant materials, with good mechanical strength and wear resistance.

[0053] Axial flow propeller 320: Fixed to the axial center of impeller disk 310, arranged in a spiral shape. When the centrifugal pump impeller 300 rotates, the liquid is guided by the axial flow propeller 320 to achieve axial flow, thereby improving pumping efficiency.

[0054] Rotor disc base 330: Fixed to the bottom of impeller disc 310, made of metal or composite material, with several permanent magnet blocks 331 embedded on the surface.

[0055] Specifically, the axial flow propeller 320 is fixed to the axis of the impeller disk 310, and the impeller disk 310 is used to realize the axial transport of liquid along the surface of the axial flow propeller 320 during rotational motion.

[0056] 4. The function of permanent magnet blocks and electromagnetic drive disks

[0057] The permanent magnet blocks 331 are evenly arranged along the circumference of the rotor disk 330 to form a ring structure.

[0058] The electromagnetic drive disk 400 has several electromagnetic coils embedded inside, which form magnetic coupling with the permanent magnet block 331 through alternating electromagnetic field. The top surface of the electromagnetic drive disk 400 is provided with an anti-corrosion layer that seals with the bottom surface of the pump box 100, which is used to isolate the liquid flow inside the pump box 100 from contact with the electromagnetic drive disk 400.

[0059] When the electromagnetic coil on the electromagnetic drive disk 400 is energized, an alternating magnetic field is formed, which drives the permanent magnet block 331 to generate magnetic force, thereby driving the centrifugal pump wheel 300 to rotate, realizing contactless drive and reducing wear and energy loss.

[0060] Specifically, the bottom surface of the electromagnetic drive disk 400 is adhered and fixed to the bottom surface of the heat dissipation base 200, and the upper and lower surfaces of the electromagnetic drive disk 400 are respectively provided with an anti-corrosion sealing layer and a heat-conducting layer is provided between the heat dissipation base 200. The anti-corrosion layer is sealed to the bottom of the pump box 100. The heat dissipation base 200 and the heat dissipation fins 210 are integrally formed structures and are made of metal.

[0061] 5. Structure and function of the agitator

[0062] The agitator 340 is fixedly connected to the bottom end of the impeller disk 310 and is located on the bottom surface of the heat dissipation base 200.

[0063] The agitator 340 rotates synchronously with the centrifugal pump wheel 300 during rotation. Through the interaction with the heat dissipation fins 210, it causes turbulence in the liquid inside the pump chamber, thereby improving heat transfer efficiency and the uniform mixing effect of the liquid.

[0064] 6. Working Principle

[0065] When dilute sulfuric acid is injected into the pump box 100 through the inlet port 110, the dilute sulfuric acid is guided to the surface of the axial flow impeller 320 by the rotation of the centrifugal pump wheel 300, generating axial flow.

[0066] When the electromagnetic coil in the electromagnetic drive disk 400 is energized, it forms an alternating magnetic field, which interacts with the permanent magnet block 331 on the rotor disk base 330, driving the centrifugal pump wheel 300 to rotate at high speed.

[0067] During rotation, the centrifugal pump impeller 300 pumps dilute sulfuric acid from the pump chamber to the drain hole 120 through the impeller disk 310 and the axial flow propeller 320, forming a continuous output.

[0068] Meanwhile, the agitator 340 disturbs the heat dissipation fins 210 at the bottom of the heat dissipation base 200 during rotation, thereby enhancing heat dissipation efficiency and preventing the electromagnetic drive disk 400 from overheating.

[0069] The heat-conducting layer quickly dissipates heat between the electromagnetic drive disk 400 and the heat sink base 200, improving the overall system's cooling capacity.
