Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump technology, specifically a centrifugal pump with antifreeze function. Background Technology

[0002] Centrifugal pumps are designed based on the principle of centrifugal force. The high-speed rotating impeller blades drive the water to rotate, throwing the water outwards, thus achieving the purpose of transportation. There are many types of centrifugal pumps, which can be divided into civilian and industrial pumps based on their use, and into clean water pumps, impurity pumps, and corrosion-resistant pumps based on the medium they transport.

[0003] Currently, existing centrifugal pumps are prone to damage in winter due to the low temperatures, which can cause the liquid remaining inside the pump to solidify and reduce its service life. Therefore, a centrifugal pump with antifreeze function is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a centrifugal pump with antifreeze function, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a centrifugal pump with antifreeze function, including a centrifugal pump body, an antifreeze mechanism provided on the centrifugal pump body, and a filter mechanism provided on the antifreeze mechanism; The antifreeze mechanism includes: a protective shell, which is fixedly fitted onto the outside of the centrifugal pump body; a water tank connected to the back of the protective shell; an electric heating plate connected to the inner wall of the back of the water tank; an electric heating wire disposed inside the electric heating plate; a rotating shaft rotatably connected to the inner right side of the water tank via a bearing; an auxiliary shaft rotatably connected to the inner right side of the protective shell via a bearing; pulleys connected to the left ends of both the rotating shaft and the auxiliary shaft; a toothed synchronous belt connecting the two pulleys; a water scoop connected to the surface of the toothed synchronous belt; and a motor connected to the right side of the water tank. The right end of the rotating shaft is connected to the output end of the motor. The water in the water tank is heated by activating the electric heating plate. The rotating shaft and pulley are driven to rotate by activating the motor, and the auxiliary shaft is driven to rotate synchronously by the toothed synchronous belt. At the same time, the water scoop on the toothed synchronous belt scoops hot water from the water tank, which is then transported to the protective shell after passing through the moving channel. As the water scoop continues to move and rotate, the hot water is poured onto the pump casing of the centrifugal pump body. Heat transfer prevents the residual liquid inside the pump from freezing, thus continuously keeping the pump casing warm through hot water circulation. This solves the problem of pump damage caused by the freezing of residual liquid in winter and extends the service life of the centrifugal pump.

[0006] Preferably, there are several water scoops, each connected to the surface of the toothed synchronous belt. The water scoops continuously scoop hot water from the water tank into the protective shell, thereby improving heating efficiency and enhancing the antifreeze effect.

[0007] Preferably, the protective shell and the water tank have moving channels on their opposite sides, and the toothed synchronous belt is located in the moving channel. The moving channel provides movement space for the toothed synchronous belt and the water scoop, ensuring that hot water is accurately delivered from the water tank to the protective shell, while preventing hot water leakage and maintaining circulation efficiency.

[0008] Preferably, a fixing plate is connected to the right side of the protective shell, and the centrifugal pump body is connected to the fixing plate by bolts, which enhances the overall structural stability.

[0009] Preferably, the filtration mechanism includes: a first return pipe and a second return pipe. The first return pipe is connected to the bottom of the protective shell, and the second return pipe is connected to the lower front of the water tank. An installation cylinder is connected between the second return pipe and the first return pipe, and they are interconnected. Hot water in the protective shell flows into the installation cylinder through the first return pipe, and after filtration, it returns to the water tank through the second return pipe. This removes impurities from the water, preventing them from clogging the scoop or affecting the heating efficiency of the electric heating plate, ensuring smooth water circulation, and reducing the frequency of manual cleaning.

[0010] Preferably, a filter screen is inserted inside the mounting cylinder, which can intercept impurities in the circulating water. A sealing cap is threaded on the left side of the mounting cylinder. The filter screen can be removed for cleaning or replacement by unscrewing the sealing cap. The operation is simple, does not affect the overall water circulation, ensures long-term stable filtration effect, and improves the practicality of the equipment.

[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. This centrifugal pump with antifreeze function heats the water in the tank by activating an electric heating plate. The motor drives the rotating shaft and pulley to rotate, and the toothed synchronous belt drives the auxiliary shaft to rotate synchronously. At the same time, the water scooping bucket on the toothed synchronous belt scoops hot water from the tank, which is then transported to the protective shell through the moving channel. As the water scooping bucket continues to move and rotate, the hot water is poured onto the pump casing of the centrifugal pump body. Heat transfer prevents the residual liquid inside the pump from freezing, thus continuously keeping the pump casing warm through hot water circulation. This solves the problem of pump damage caused by residual liquid freezing in winter and extends the service life of the centrifugal pump.

[0012] 2. This centrifugal pump with antifreeze function allows hot water inside the protective shell to flow into the installation cylinder through the first return pipe. After filtration, it returns to the water tank through the second return pipe, removing impurities from the water and preventing them from clogging the scoop or affecting the heating efficiency of the electric heating plate. This ensures smooth water circulation, reduces the frequency of manual cleaning, and the filter screen can be removed for cleaning or replacement by unscrewing the sealing cap. The operation is simple, does not affect the overall water circulation, ensures long-term stable filtration effect, and improves the practicality of the equipment. Attached Figure Description
