Description

Technical Field

[0001] This utility model relates to a vertical self-priming pump, specifically a vertical self-priming pump with slag-blocking function, belonging to the field of self-priming pump technology. Background Technology

[0002] Self-priming pumps are a type of self-priming centrifugal pump, characterized by their compact structure, convenient operation, stable running, easy maintenance, high efficiency, long service life, and strong self-priming capability. No foot valve is required in the pipeline; only a measured amount of priming liquid needs to be present in the pump body before operation. Different materials can be used for self-priming pumps depending on the liquid. The working principle of a self-priming pump is as follows: before starting the pump, the pump casing is filled with water. After starting, the impeller rotates at high speed, causing the water in the impeller channels to flow towards the volute. At this time, a vacuum is formed at the inlet, opening the inlet check valve and allowing air from the suction pipe to enter the pump and reach the outer edge through the impeller channels.

[0003] Chinese Patent No. CN215805370U provides a vertical self-priming pump, which includes a motor, a motor base, a motor shaft, a motor seat, a motor coupling, a pump coupling, a bearing cover, a bearing seat, a sealing shell, a liquid inlet seat, an impeller shell, a housing, a base, a cleaning bin, a cleaning port, a feed port, a discharge port, and a pump shaft; a negative impeller is also provided below the sealing shell and around the outer periphery of the pump shaft. The pumped liquid is blocked by the rotating negative impeller before entering the sealing shell and bearing seat and causing contamination, thereby further reducing the risk of entering the sealing shell and bearing seat.

[0004] However, while the above-mentioned cases reduce the risk of impurities entering the sealing shell and bearing housing, they do not have a slag-blocking function, and impurities can easily enter the vertical self-priming pump, causing blockage or damage to the pump.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a vertical self-priming pump with slag-blocking function to solve the above-mentioned problems.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a vertical self-priming pump with slag-blocking function, comprising a self-priming pump assembly, the self-priming pump assembly comprising a pump body, a drive motor mounted on the top of the pump body, an output pipe and an inlet pipe respectively mounted on both sides of the pump body, a flange fixed to one end of each of the output pipe and the inlet pipe, a fixing hole on one side of the flange, a slag-blocking assembly provided at one end of the inlet pipe, the slag-blocking assembly comprising a main slag-blocking tank and a secondary slag-blocking tank, both of the main slag-blocking tank and the secondary slag-blocking tank being provided with a filter screen, a filter screen, filter cotton and an ultrafiltration membrane arranged sequentially from left to right inside, a connecting assembly installed on both sides of the slag-blocking assembly, the connecting assembly comprising a three-way main pipe, a three-way secondary pipe connected to the bottom of the three-way main pipe, and a one-way assembly provided at one end of the output pipe.

[0008] Furthermore, the unidirectional component includes a housing, a fixing tube installed inside the housing, a guide frame installed inside the fixing tube, and a sliding rod slidably inserted inside the guide frame.

[0009] Furthermore, a hinge plate is fixed to the top of the sliding rod, and a sealing gasket is provided at the bottom of the hinge plate.

[0010] Furthermore, flange four is installed at both the top and bottom of the outer casing, and a fixing hole four is opened at the top of flange four. The outer casing is installed at one end of the output pipe through flange four and flange one.

[0011] Furthermore, a main valve is installed on one side of the tee main pipe, and a secondary valve is installed on one side of the tee secondary pipe.

[0012] Furthermore, flange 2 is fixed to both ends of the main tee pipe and one end of the secondary tee pipe, and a fixing hole 2 is opened on one side of the flange 2.

[0013] Furthermore, both ends of the main slag-blocking tank and the auxiliary slag-blocking tank are equipped with flange three, and a fixing hole three is opened on one side of the flange three. The connecting component is installed at both ends of the slag-blocking component through the cooperation of flange two and flange three.

[0014] Furthermore, a mounting plate is installed at the bottom of the pump body, and a mounting hole is opened at the top of the mounting plate.

[0015] The technical effects and advantages of this utility model are as follows: (1) Through the slag-blocking component, both the main slag-blocking tank and the auxiliary slag-blocking tank in the slag-blocking component are equipped with filter screens, filter cotton and ultrafiltration membranes, which can filter large, medium and small impurities in sequence to ensure the cleanliness of the water entering the vertical self-priming pump. At the same time, the use of the main slag-blocking tank and the auxiliary slag-blocking tank makes it easy to clean one of the tanks without affecting the normal use of the vertical self-priming pump; (2) Through the connecting component, two valves are used in the connecting component, which makes it easy to control the use of the main slag-blocking tank and the auxiliary slag-blocking tank separately, and makes it easy to clean the main slag-blocking tank and the auxiliary slag-blocking tank. Switching is performed to ensure that the vertical self-priming pump works continuously; (3) When the hinge plate inside the one-way component receives the impact force of the discharged water, the hinge plate moves upward, so that the water passes through the outer shell of the one-way component. When the water pressure above the hinge plate is greater than the water pressure below, the hinge plate falls back onto the fixed pipe, which can prevent water from flowing back into the pump body and ensure the stability of the vertical self-priming pump. The sliding rod is slid in the guide frame, which can ensure the stability of the hinge plate lifting and lowering. At the same time, the bottom end of the sliding rod is fixed with a limit plate to prevent the sliding rod from leaving the guide frame and improve the stability of the hinge plate.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, a vertical self-priming pump with slag-blocking function includes a self-priming pump assembly 100. The self-priming pump assembly 100 includes a pump body 101. A drive motor 102 is installed on the top of the pump body 101. An output pipe 104 and an inlet pipe 105 are respectively installed on both sides of the pump body 101. A flange 106 is fixed to one end of both the output pipe 104 and the inlet pipe 105. A fixing hole 107 is opened on one side of the flange 106. An mounting plate 103 is installed at the bottom of the pump body 101. The pump body 101 is fixed to a designated position by the mounting plate 103. An mounting hole 108 is opened on the top of the mounting plate 103.

[0023] A slag-blocking assembly 300 is installed at one end of the inlet pipe 105. The slag-blocking assembly 300 includes a main slag-blocking tank 301 and a secondary slag-blocking tank 302. The use of the main slag-blocking tank 301 and the secondary slag-blocking tank 302 makes it easy to clean one of the tanks without affecting the normal operation of the vertical self-priming pump. The interior of the main slag-blocking tank 301 and the secondary slag-blocking tank 302 is provided with a filter screen 303, a filter screen 304, a filter cotton 305 and an ultrafiltration membrane 306 from left to right. The filter screen, the filter cotton 305 and the ultrafiltration membrane 306 can filter large, medium and small impurities in sequence to ensure the cleanliness of the water entering the vertical self-priming pump. Both ends of the main slag-blocking tank 301 and the secondary slag-blocking tank 302 are equipped with flanges 307. One side of the flanges 307 has a fixing hole 308. The connecting assembly 200 is installed at both ends of the slag-blocking assembly 300 through the cooperation of flanges 205 and 307.

[0024] Both sides of the slag blocking assembly 300 are equipped with connecting components 200. The connecting components 200 include a three-way main pipe 201, and a three-way auxiliary pipe 202 connected to the bottom of the three-way main pipe 201. One end of the output pipe 104 is equipped with a one-way component 400. A main valve 203 is installed on one side of the three-way main pipe 201, and an auxiliary valve 204 is installed on one side of the three-way auxiliary pipe 202. The connecting components 200 use two valves to facilitate the independent control of the use of the main slag blocking tank 301 and the auxiliary slag blocking tank 302, and to facilitate switching between the main slag blocking tank 301 and the auxiliary slag blocking tank 302 during cleaning. Both ends of the three-way main pipe 201 and one end of the three-way auxiliary pipe 202 are fixed with flanges 205. A fixing hole 206 is opened on one side of the flanges 205.

[0025] As a technical optimization of this utility model, the unidirectional component 400 includes a housing 401, a fixing tube 402 installed inside the housing 401, a guide frame 403 installed inside the fixing tube 402, and a sliding rod 404 slidably inserted inside the guide frame 403 to ensure the stability of the hinge plate 405 during lifting. Simultaneously, a limit plate is fixed to the bottom end of the sliding rod 404 to prevent the sliding rod 404 from detaching from the guide frame 403, thus improving the stability of the hinge plate 405 during use. The hinge plate 405 is fixed to the top of the sliding rod 404. When the hinge plate 405 receives the impact force of the discharged water... The hinge plate 405 moves upward, allowing water to pass through the housing 401 of the one-way component 400. When the water pressure above the hinge plate 405 is greater than the water pressure below, the hinge plate 405 falls back onto the fixed pipe 402, preventing water from flowing back into the pump body 101 and ensuring the stability of the vertical self-priming pump. A sealing gasket 406 is provided at the bottom of the hinge plate 405. Flanges 407 are installed at the top and bottom of the housing 401. A fixing hole 408 is opened at the top of the flange 407. The housing 401 is installed at one end of the output pipe 104 through the flange 407 and the flange 106.

[0026] In use, the self-priming pump assembly 100 is installed and fixed in a designated position via the mounting plate 103. One end of the slag-blocking assembly 300 is connected to the inlet pipe 105 on one side of the pump body 101 via the connecting assembly 200, and the other end of the slag-blocking assembly 300 is connected via another connecting assembly 200. Water first passes through the slag-blocking assembly 300 and enters the inlet pipe 105. Since both the main slag-blocking tank 301 and the auxiliary slag-blocking tank 302 are equipped with filter screens, filter cotton 305, and ultrafiltration membranes 306, they can sequentially and thoroughly filter large, medium, and small impurities, ensuring the cleanliness of the water entering the vertical self-priming pump. Furthermore, the use of the main slag-blocking tank 301 and the auxiliary slag-blocking tank 302 facilitates cleaning one of the tanks without affecting the vertical self-priming pump. During normal use, since a one-way component 400 is installed at the top of the output pipe 104, when the hinge plate 405 inside the one-way component 400 receives the impact force of the discharged water, the hinge plate 405 moves upward, allowing water to pass through the outer shell 401 of the one-way component 400. When the water pressure above the hinge plate 405 is greater than the water pressure below, the hinge plate 405 falls back onto the fixed pipe 402, which can prevent water from flowing back into the pump body 101 and ensure the stability of the vertical self-priming pump. The sliding rod 404 slides in the guide frame 403, which can ensure the stability of the hinge plate 405 in raising and lowering. At the same time, the bottom end of the sliding rod 404 is fixed with a limit plate to prevent the sliding rod 404 from disengaging from the guide frame 403, thereby improving the stability of the hinge plate 405 in use.

[0027] When the slag-blocking tank needs to be cleaned, the two valves in the connecting component 200 facilitate the separate control of the main slag-blocking tank 301 and the auxiliary slag-blocking tank 302, and make it easy to switch between the main slag-blocking tank 301 and the auxiliary slag-blocking tank 302 during cleaning, ensuring that the vertical self-priming pump works continuously.
