[0002] Circulating pumps are an essential component of industrial, commercial, and residential heating and cooling systems. They maintain fluid circulation and ensure smooth and effective circulation in small closed-loop circuits, such as hot water systems and independent home heating systems. Circulating pumps utilize superior hydraulic models and advanced manufacturing processes to enhance pump performance and service life. The shaft seal utilizes a mechanical seal made of carbide and fluororubber, enhancing pump reliability and ensuring the temperature of the conveyed medium.

It comprises: a volute; an impeller disposed within the volute; a water-blocking strip disposed transversely relative to the fluid flow direction on the inner wall of the volute along the fluid flow direction; a hanging net disposed transversely relative to the fluid flow direction on the inner wall of the volute along the fluid flow direction; and a support seat disposed at the bottom end of the volute and fixedly connected to the volute. This utility model can ensure stable operating quality, is not susceptible to corrosion damage during operation, and significantly improves operational reliability and safety. Furthermore, if the circulating pump housing is damaged, it can be repaired on-site, thereby extending the service life of the desulfurization circulating pump housing and improving operating efficiency.

[0004] However, the above-mentioned desulfurization circulation pump has the following problems: unilateral circulation does not have a cleaning function, and the circulation pump is easily corroded by residual substances when used for a long time. Moreover, when circulating certain high-temperature sulfide liquids, the circulation pump cannot be protected from damage. Summary of the Invention

[0005] The utility model overcomes the deficiencies of the prior art and provides a circulating pump suitable for corrosive media.

[0006] To achieve the above-mentioned object, the technical solution adopted by the present invention is as follows: a circulating pump suitable for corrosive media, comprising: a base, a fixing mechanism arranged on the base, a braking mechanism arranged on the fixing mechanism, and a circulating mechanism arranged on the base;

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0028] like Figure 1-Figure 2 As shown, a circulating pump suitable for corrosive media includes: a base 1, a fixing mechanism arranged on the base 1, a braking mechanism arranged on the fixing mechanism, and a circulating mechanism arranged on the base 1;

[0029] In the present invention, the fixing mechanism includes: a first fixing block 2 disposed on a base 1, and a second fixing block 3 disposed at the other end of the base 1; the first fixing block 2 is fixedly connected to the base 1 via a first screw 4, and the second fixing block 3 is fixedly connected to the base 1 via a second screw 5. The first fixing block 2 is used to fix the motor 6, and the second fixing block 3 is used to fix the liquid inlet pump 7. The screw fixation ensures the stability of the first and second fixing blocks 2 and 3 on the base 1, reducing vibration and noise during operation. The screw connection method facilitates disassembly and maintenance, facilitating regular inspection and maintenance of the motor 6 and the liquid inlet pump 7.

[0030] In the present invention, the braking mechanism includes: a motor 6 connected to the first fixing block 2, and an electric shaft 19 connected to one end of the motor 6; the motor 6 serves as a power source of the circulation pump and is responsible for driving the operation of the pump.

[0031] In this utility model, the circulation mechanism includes an inlet pump 7 mounted on the second fixed block 3 and an outlet pump 8 connected to the inlet pump 7. Both the outlet pump 8 and the inlet pump 7 are constructed of stainless steel. The inlet pump 7 draws the medium from the liquid storage container into the pump, while the outlet pump 8 discharges the medium from the pump, completing the circulation process. Stainless steel's high strength and durability mean that the pump components can withstand long periods of operation and high pressures without easily breaking down.

[0032] In the present invention, the other end of the electric shaft 19 is connected to a coupling 13, the other end of the coupling 13 is connected to a support rod 14, the other end of the support rod 14 is connected to a rotating shaft 15, and one end of the rotating shaft 15 is connected to a plurality of impellers 16. The motor 6 shaft is responsible for transmitting the rotational power generated by the motor 6 to the coupling 13. The coupling 13 is used to connect the motor 6 shaft and the support rod 14 to transmit power while allowing a certain axial and angular deviation to reduce damage caused by poor alignment. The rotating shaft 15 is responsible for transmitting power to the impeller 16, driving the impeller 16 to rotate, thereby realizing the circulation of the medium. The impeller 16 is the core component of the pump. It generates centrifugal force through rotation, transporting the medium from the inlet pump 7 to the outlet pump 8, realizing the circulation of the medium.

[0033] In the present invention, a first chain 9 is provided at one end of the inlet pump 7, and the other end of the first chain 9 is connected to a first cover plate 11. A second chain 10 is provided at one end of the outlet pump 8, and the other end of the second chain 10 is connected to a second cover plate 12. The first cover plate 11 and the second cover plate 12 are used to seal the inlet and outlet of the inlet pump 7 and the outlet pump 8 to prevent leakage of the medium and entry of foreign matter.

[0034] In the present invention, a plurality of cooling tubes 17 are provided at one end of the liquid outlet pump 8, each of which has a cooling inlet 18 at one end. The primary function of the cooling tubes 17 is to absorb and transfer heat generated by the liquid outlet pump 8 during operation by circulating cooling liquid, thereby helping to maintain the pump's optimum operating temperature and preventing damage to the equipment due to overheating. By introducing cooling liquid through the cooling inlet 18, the temperature of the liquid outlet pump 8 can be effectively controlled. When handling high-temperature and corrosive media, the cooling system prevents overheating of the pump body and extends the pump's service life.

[0035] When the present invention is used, first, the motor 6 connected to the first fixed block 2 is started, and the motor 6 transmits power through the electric shaft 19. The other end of the electric shaft 19 is connected to the coupling 13, and the coupling 13 transmits power to the support rod 14. The other end of the support rod 14 is connected to the rotating shaft 15, and one end of the rotating shaft 15 is connected to a plurality of impellers 16. The impeller 16 starts to rotate under the drive of the power, generating centrifugal force. The liquid inlet pump 7 is located on the second fixed block 3. The rotation of the impeller 16 forms a negative pressure at the liquid inlet pump 7, and the corrosive medium is sucked into the pump from the liquid storage container. After passing through the liquid inlet pump 7, the corrosive medium is accelerated by the impeller 16 and sent to the liquid outlet pump 8. The outlet pump 8 further pressurizes the medium, circulates it into the system and equipment, and is transported to the desired location to complete the circulation process. If the temperature of the circulating pump is too high, the cooling liquid enters the cooling pipe 17 through the cooling liquid inlet 18 to help reduce the temperature of the pump body and prevent overheating. When cleaning the circulating pump, you can open the first cover 11 or the second cover 12, pour in the cleaning liquid and clean water, then cover the cover, start the motor 6 to rotate the impeller 16, and accelerate the flow rate of the cleaning liquid to improve the cleaning efficiency. After cleaning, open the cover to let the cleaning liquid flow out. Frequent cleaning of the circulating pump can reduce corrosion and extend the service life of the circulating pump.

[0036] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention.
