Description

Technical Field

[0001] The present invention relates to the technical field of centrifugal pumps, in particular to a magnetically driven horizontal centrifugal pump. Background Art

[0002] A magnetically driven horizontal centrifugal pump utilizes a magnetic coupling for contactless torque transmission. Its core characteristic is complete leakage resistance, making it particularly suitable for conveying flammable, explosive, highly toxic, or corrosive media. The pump shaft is mounted horizontally, making it suitable for high flow rates and low to medium head applications. Its core component, the magnetic actuator, consists of an outer magnetic rotor, an inner magnetic rotor, and a spacer sleeve. The outer magnetic rotor penetrates the spacer sleeve through its magnetic field, driving the inner magnetic rotor in synchronous rotation, ensuring the media is completely enclosed within the sleeve. This design ensures exceptional safety when conveying flammable, explosive, highly toxic, and other hazardous media, making it a leading choice for leak-free conveying.

[0003] When a magnetically driven horizontal centrifugal pump is used, the cleanliness of the medium conveyed by the centrifugal pump is significantly sensitive. For example, the existing patent publication number is CN117404341A, which specifically relates to a magnetically driven centrifugal pump with a filtering structure. The present invention relates to the technical field of magnetically driven centrifugal pumps, comprising a pump body, an inlet is provided at one end of the pump body, a filtering mechanism is provided on one side of the inlet, a motor drive shaft is provided inside the pump body, a driving mechanism is provided between the motor drive shaft and the filtering mechanism, and a protective mechanism is provided on the outside of the driving mechanism. The magnetically driven centrifugal pump filters the liquid by using a filter screen to prevent debris from entering the pump body; the cleaning plate is driven by a micro motor to scrape the filter screen and collect impurities into a collection box, thereby reducing the damage caused by impurities to the pump body.

[0004] However, the above invention still has some shortcomings in practical use: 1. This filtering structure cannot filter small magnetic impurities in the medium, which will cause structural wear in the centrifugal pump. Magnetic impurities will also be adsorbed on the magnet, causing the magnet to load and interfering with the efficiency of magnetic force transmission. For these reasons, it is necessary to design a magnetically driven horizontal centrifugal pump that can effectively intercept impurities and improve the cleanliness of the transported liquid.

[0020] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] See also Figure 1-7 , the present invention provides a technical solution: A magnetically driven horizontal centrifugal pump. Currently, the inlet pipe 2 and input end 3 of the horizontal centrifugal pump are mostly arranged with liquid input in the horizontal direction and liquid output in the vertical direction. The pump body 1 is electrically driven by a micromotor. After use, a cleaning structure rubs the filter plate in the centrifugal pump to clean impurities in the transported liquid and prevent blockage. However, when this structure is used for a long time, the cleaning structure will experience varying degrees of wear, reducing the filtering effect. Therefore, the present invention adopts a high-level drop input method, using liquid level differences and magnetic adsorption to perform multi-stage filtration to reduce impurities and magnetic substances in the liquid. First, the opening of the inlet pipe 2 is set upward, and the water source is input vertically through the inlet pipe 2 into the collection barrel 4, which is set through the lower end. By rotating the centrifugal separation component 5 set in the collection barrel 4, the gravity and potential energy of the input water source are used to flush the centrifugal separation component 5 to centrifugally rotate the liquid, centrifugally separating the impurities in the water from the liquid and throwing them toward the inner wall of the collection barrel 4. As the impurities are gathered downward due to gravity and centrifugal force, the impurities in the liquid are initially filtered. Next, a magnetic filter end 7 can be horizontally set on one side of the upper end of the collection barrel 4, and the other end of the magnetic filter end 7 can be connected to the input end 3. The supernatant after filtering in the collection barrel 4 is transferred to the side through the principle of the communicating vessel, and the magnetic filter end 7 is used to filter the magnetic impurities in the liquid again to achieve the cleaning of the magnetic impurities.

[0022] Among them, it is worth mentioning that in order to facilitate the secondary filtration of magnetic impurities in the liquid, the input end 3 and the magnetic filtration end 7 can be vertically distributed, and the diameter of the input pipe 2 can be set to be smaller than 1 / 4 of the inner diameter of the collection bucket 4. Through the diameter difference between the input pipe 2 and the collection bucket 4, the input liquid can be fully separated from impurities, thereby improving the liquid cleaning efficiency.

[0023] Furthermore, the input liquid will flush the centrifugal separation component 5, and the liquid's own potential energy will be used to drive the centrifugal component, thus reducing energy consumption. The centrifugal separation component 5 can be driven to rotate, and the rotating centrifugal separation component 5 will centrifugally rotate the liquid in the collection barrel 4, causing the impurities in the liquid to be thrown toward the inner wall of the collection barrel 4 and finally fall into the transfer end 6, thus achieving the separation of the impurities. Figure 2 、 3 As shown in Figure 4, in some embodiments, the centrifugal separation component 5 is supported by a bracket arranged inside the collecting barrel 4, the bracket is suspended on the upper side of the transfer end 6, and then a shaft is vertically arranged in the middle of the bracket, the shaft is rotatably arranged on the bracket, and is used coaxially with the collecting barrel 4; then, a drainage bucket 9 and two groups of centrifugal blades 12 can be arranged in sequence from top to bottom on the outside of the shaft; wherein, the wide-mouth end of the drainage bucket 9 is arranged downward, and the narrow-mouth end of the drainage bucket 9 is opposite to the outlet end of the input pipe 2 up and down, and a plurality of force-bearing blades 10 are arranged in an annular manner on the outer side of the drainage bucket 9, and the lower end of the force-bearing blade 10 is arranged as a driving arc portion 11 recessed to one side, each group of centrifugal blades 12 are arranged in an annular manner on the shaft, and an inwardly recessed driving groove is provided on one side of the top of each centrifugal blade 12, and the centrifugal blades 12 are inclined up and down (extending outward) at an angle of 30°-60° to the shaft.

[0024] When high-level liquid is input into the collection barrel 4, the liquid first contacts the drainage bucket 9. The structural characteristics of the drainage bucket 9 and the downward setting of its wide-mouth end are used to guide the liquid to the centrifugal blades 12 below. The inclination angle of the centrifugal blades 12 is preferably 45°. At this angle, the centrifugal efficiency and the liquid throughput rate reach an optimal balance; at the same time, the liquid drives the centrifugal separation assembly 5 to rotate through the force-bearing blades 10 and the lower end driving arc portion 11. The synergistic effect of the liquid force-bearing blades 10 and the centrifugal blades 12 causes the driving grooves of the centrifugal blades 12 to also withstand the impact force of the liquid, and synchronously stirs the liquid in the collection barrel 4. Among them, the force-bearing blades 10 provide initial rotational power, and the centrifugal blades 12 maintain rotation through liquid impact, throwing impurities to the inner wall of the collection barrel 4, thereby realizing centrifugal separation of impurities.

[0025] Then, with the rotation drive of the centrifugal separation component 5 and the collection bucket 13 provided below the collecting barrel 4, the impurities are gathered below. The transfer end 6 is provided at the lower end of the collecting barrel 4, and the impurities can be centrifugally transferred to the transfer end 6. Figure 3As shown, in some embodiments, the transfer end 6 includes a collecting bucket 13 that is arranged through the collecting barrel 4, and an extended output pipe 14 is arranged through the lower end of the collecting bucket 13 for separating the impurities from the liquid. Then, a one-way valve 15 is provided at the lower end of the extended output pipe 14, and a timing switch module is provided in the one-way valve 15, wherein the timing switch module can be adjusted according to the frequency of using the centrifugal pump and the neatness of the transported liquid. Generally, it can be set to open once every 1-5 days. Through the timing switch of the one-way valve 15, the impurities in the extended output pipe 14 can be discharged regularly, thereby realizing the transfer of impurities, reducing labor maintenance costs, and preventing the accumulation of impurities in the collecting barrel 4.

[0026] Furthermore, when the supernatant of the liquid separated from the collecting barrel 4 is transferred, the filtering process can be performed at the connection between the collecting barrel 4 and the magnetic filter end 7. Figure 3 As shown, in some embodiments, the magnetic filter end 7 and the collecting barrel 4 can be first penetrated, and the inner wall of the collecting barrel 4 is provided with an oblique filter cover 16 that is sleeved on the magnetic filter end 7, and then the lower end of the oblique filter cover 16 is tilted downward without affecting the rotation of the centrifugal separation component 5. When the liquid level in the collecting barrel 4 is higher than the magnetic filter end 7, the supernatant can pass through the oblique filter cover 16 into the magnetic filter end 7. The downward tilt of the lower end of the oblique filter cover 16 can filter impurities, and at the same time, it is convenient for the transfer end 6 to transfer impurities, and the outer surface of the oblique filter cover 16 is cleaned to achieve impurity blocking treatment, thereby increasing the smoothness of liquid transfer from the collecting barrel 4 to the magnetic filter end 7.

[0027] Secondly, if Figure 3 and 5 As shown, in some embodiments, the transferred supernatant liquid is passed into the collection tube 17 of the magnetic filter end 7, and a separation blade group 20 is coaxially arranged inside the collection tube 17. The separation blade group 20 can be rotated in the collection tube 17 by the impact of the supernatant liquid, and the liquid passed into the magnetic filter end 7 is rotated and mixed, so that the liquid contacts the inner wall of the collection tube 17 over a larger area, and the fine impurities are centrifugally thrown toward the inner wall of the collection tube 17 again; at the same time, an electromagnetic ring 18 is also provided on the inner side of the collection tube 17, and an electromagnetic control end 19 connected to the electromagnetic ring 18 is provided on the outer side of the collection tube 17. The electromagnetic ring 18 is made of neodymium iron boron magnetic material, and the magnetic field strength can be adjusted by the electromagnetic control end 19 to adapt to the treatment of liquids with different magnetic impurity contents; when the centrifugal pump is in use, the electromagnetic control end 19 energizes the electromagnetic ring 18, so that the electromagnetic ring 18 has magnetism, adsorbs the magnetic substance in the liquid inside the collection tube 17, and the magnetic impurities are retained on the electromagnetic ring 18, thereby realizing the centrifugal removal of magnetic impurities.

[0028] Furthermore, if Figure 5As shown, in some embodiments, a filter plate 21 can be further provided on the side of the magnetic filter end 7 close to the input end 3. In some embodiments, the filter plate 21 can be tilted, and its mesh is smaller than the mesh of the oblique filter cover 16, so as to finely filter the impurities again; then, an inwardly contracted output hopper 22 is provided on the outer side of the filter plate 21 to guide and pressurize the filtered liquid, thereby increasing the flow rate of the liquid input by the centrifugal pump.

[0029] The supernatant entering the magnetic filtration end 7 enters the collection tube 17 through the oblique filter cover 16, and then passes through the centrifugal filtration of the separation blade group 20, the magnetic adsorption of the electromagnetic ring 18, and the fine filtration of the filter plate 21, and finally enters the input end 3 through the output hopper 22 for use by the pump body 1.

[0030] In order to achieve long-term operation of the centrifugal pump, Figure 6 and 7 As shown, in some embodiments, an impurity collection end 8 can be provided at the lower end of the magnetic filter end 7 as an impurity transfer structure to prevent the magnetic filter end 7 from being blocked. The impurity collection end 8 includes a waste valve 23 that is connected to the electromagnetic ring 18. The waste valve 23 can use an existing electromagnetic valve and can be set together with the one-way valve 15 to open once every 1-5 days, thereby reducing the number of separate operation steps and improving the cleaning efficiency. A transfer barrel 24 is then provided at the lower end of the waste valve 23. The transfer barrel 24 and the waste valve 23 adopt a quick-release structure to facilitate regular cleaning and maintenance. A detachable plug 26 is provided at the lower end of the transfer barrel 24, and the top of the plug 26 is located inside the transfer barrel 24. A partition barrel 25 is provided, which is a hollow structure; the hollow aperture of the partition barrel 25 is the same as the aperture of the filter plate 21; the electromagnetic ring 18 is powered off by the electromagnetic control end 19, the magnetism of the electromagnetic ring 18 disappears, the impurity removal valve 23 can be opened, and the adsorbed magnetic impurities are separated from the electromagnetic ring 18 and flow with the liquid to the transfer barrel 24, thereby transferring the magnetic impurities; at the same time, the direction of the liquid flow at the input end 3 can drive the impurities isolated on the filter plate 21 to pass through the impurity removal valve 23, thereby realizing the anti-blocking treatment of the filter plate 21. Among them, a detachable mounting seat is set at the lower end of the transfer barrel 24 to facilitate the opening of the transfer barrel 24. A partition barrel 25 is set inside the transfer barrel 24 on the top of the mounting seat. Finally, a same plug 26 is set between the partition barrel 25 and the transfer barrel 24 as the discharge end of the liquid; when the transfer barrel 24 is full of liquid, the transfer barrel 24 can be separated from the impurity discharge valve 23, and the hollow structure of the partition barrel 25 can block impurities. By pulling out the plug 26, the liquid and the magnetic material can be separated and taken out, which facilitates the transfer of the magnetic material.

[0031] Working principle of the present invention: Step 1. Place the pump body 1 horizontally, and set the opening of the input pipe 2 upwards. Connect the input liquid with the input pipe 2, and inject it into the collection barrel 4 in the up and down directions through the high position of the liquid (the diameter of the input pipe 2 is less than 1 / 4 of the inner diameter of the collection barrel 4 to expand the separation space). The liquid first impacts the centrifugal separation component 5 in the collection barrel 4. After contacting the drainage bucket 9, the liquid is guided downward and simultaneously impacts the driving arc portion 11 of the force-bearing blade 10, providing initial rotational power for the centrifugal separation component 5; the centrifugal blade 12 is impacted by the liquid and its driving groove maintains rotation (the centrifugal blade 12 is inclined at 30°-60° to the shaft). Under the synergistic action of the two, the liquid entering the collection barrel 4 is subjected to centrifugal motion, and the impurities are thrown to the inner wall of the collection barrel 4, and then fall into the transfer end 6 at the lower end. The collection bucket 13 of the transfer end 6 gathers impurities to the extended output pipe 14; Step 2: The supernatant liquid from the collection barrel 4, after preliminary filtration, flows through the oblique filter housing 16 (which intercepts residual impurities) via the communicating vessel principle into the collection tube 17 at the magnetic filter end 7. The supernatant impacts the separation blade assembly 20 within the collection tube 17, causing it to rotate. Centrifugal force causes the liquid to flow along the tube wall. The electromagnetic ring 18 inside the collection tube 17 (powered by the outer electromagnetic control end 19) generates magnetism, absorbing magnetic impurities in the liquid. The liquid then flows through the filter plate 21 (with a smaller mesh size than the oblique filter housing 16) for fine filtration. Finally, after being diverted and pressurized by the output hopper 22, it enters the input end 3, supplying water to the centrifugal pump body 1. Step three, when the centrifugal pump is in use, the electromagnetic ring 18 can be timed on and off through the electromagnetic control end 19 to control the synchronous opening and closing of the one-way valve 15 and the impurity removal valve 23: when the electromagnetic control end 19 controls the electromagnetic ring 18 to be de-energized, the magnetic impurities are separated from the inner wall of the electromagnetic ring 18, and the magnetic impurities in the electromagnetic ring 18 and the impurities on the side of the filter plate 21 close to the electromagnetic ring 18 are affected by the flow of liquid and enter the transfer barrel 24 through the impurity removal valve 23; at the same time, the impurities collected in the extended output pipe 14 are discharged outward by the flow of liquid; the partition barrel 25 (hollow structure) in the transfer barrel 24 performs solid-liquid separation on the liquid output from the impurity removal valve 23, and the impurities can be cleaned regularly through the detachable plug 26.
