Description

Technical Field

[0001] This utility model belongs to the field of circulating pump technology, specifically relating to an outlet self-stabilizing energy-saving circulating pump. Background Technology

[0002] Energy-saving circulating pumps are typically made of stainless steel or cast iron. They feature compact structure, small footprint, light weight, low noise, easy operation, simple maintenance, stable performance, and long service life. They are widely used in production processes in industries such as petroleum, chemical, pharmaceutical, papermaking, printing and dyeing, brewing, power, electroplating, and environmental protection to transport various corrosive liquids or clear liquids, such as acids, alkalis, and salt solutions. They can also serve as the heart of circulating water systems, acting as a pressure booster. A search revealed that application number "CN202322640480.5" discloses "an outlet self-stabilizing energy-saving circulating pump," which describes how "by setting an adjusting bolt, adjusting pipe, central shaft, pressure regulating ring, flow limiting ring, spring, and flow limiting pipe, when the circulating pump is working, the flow limiting ring is compressed, and..." One end of the spring is compressed, causing the water outlet on the central shaft to leak. When the water pressure is unstable, the size of the water outlet is automatically adjusted by the extension and retraction of the spring, keeping the pumped water flow stable. The position of the pressure regulating ring can also be adjusted by adjusting the bolt to change the initial pressure of the water flow. This system utilizes an adjusting bolt, adjusting pipe, central shaft, pressure regulating ring, flow limiting ring, spring, and flow limiting pipe. When the circulating pump is working, the flow limiting ring is compressed, and the spring at the other end is compressed, causing the water outlet on the central shaft to leak. When the water pressure is unstable, the size of the water outlet is automatically adjusted by the extension and retraction of the spring, ensuring a stable pumped water flow. The position of the pressure regulating ring can also be adjusted by adjusting the bolt to change the initial pressure of the water flow. However, the above comparison document still has the following problems in actual use: In actual use, the adjustment is inconvenient and requires manual adjustment, which is not precise enough, resulting in unstable self-regulating pressure. In addition, it is inconvenient to filter the water flow during use, which makes the self-regulating pressure structure easy to be damaged. Utility Model Content

[0003] The purpose of this invention is to provide an outlet self-stabilizing energy-saving circulating pump, which aims to solve the above-mentioned technical problems.

[0004] This utility model provides an outlet self-stabilizing energy-saving circulating pump, including a pump body, a self-stabilizing component, and a filter and quick disassembly and cleaning component.

[0005] The pump body has a sealing connection to a connecting box on one side, and a conveying pipe is sealing connection to one side of the connecting box. The self-stabilizing component includes a protective box sealed and connected to the top of the delivery pipe. An isolation plate is provided in the middle of the protective box. Two limiting rods are provided at the top of the isolation plate. A movable plate is slidably connected to the outer wall of the two limiting rods. A connector is provided at the bottom of the movable plate. A sealing head is provided through the isolation plate at the bottom of the connector. A movable strip is provided on the outer wall of the two limiting rods. Two first springs are provided at the bottom of the movable strip. An electric cylinder is provided at the top of the protective box. The filtration and quick-release cleaning assembly includes a filter screen slidably connected inside the connecting box. A sealing cover is movably connected to the top of the connecting box. Two fixing plates are provided on the top of the sealing cover. Two auxiliary rods are provided between the two fixing plates. Two movable plates are slidably connected to the outer walls of the two auxiliary rods. A plug is provided on one side of each of the two movable plates. The ends of the two plugs pass through the fixing plates and are inserted into the fixing brackets. The ends of the two fixing brackets are fixedly connected to the connecting box.

[0006] As a preferred technical solution of this utility model, the interiors of both first springs are slidably connected to the limiting rod, the bottoms of both first springs are fixedly connected to the moving plate, and one side of the connecting box is sealed with an external connector.

[0007] As a preferred technical solution of this utility model, two second springs are provided between the two movable pieces, and the interior of each of the two second springs is slidably connected to the auxiliary rod.

[0008] As a preferred embodiment of this utility model, the tops of the two movable pieces are hinged with connecting rods, and an auxiliary plate is hinged between the two connecting rods. A pull head is provided on the top of the auxiliary plate.

[0009] As a preferred technical solution of this utility model, the output shaft end of the electric cylinder is fixedly connected to the moving bar through the protective box.

[0010] As a preferred embodiment of this invention, a pressure sensor is integrated inside the delivery pipe, and a controller is provided at the top corner of the protective box.

[0011] In a preferred embodiment of this invention, the pump body, electric cylinder, and pressure sensor are all electrically connected to the controller, and the controller is electrically connected to an external power supply.

[0012] In a preferred embodiment of this invention, the top of the spring is fixedly connected to the top of the inner wall of the protective seat, and the inner wall of the spring is slidably connected to the support column.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) When the circulating pump body sends liquid into the protective box through the connecting box and the delivery pipe, the water flow will press against the sealing head. If the water pressure is high, the sealing head will be fixed upwards. The force on the sealing head will drive the moving plate to move upwards, and then the moving plate will move on the limit rod, causing the first spring to be compressed and rebound, suppressing the high-pressure water flow and preventing the water flow from being abnormally strong due to excessive pressure. When the water flow is low, the sealing head will remain in its original position, allowing the water to flow out smoothly. It should be noted that "there is a large gap between the sealing head and the wall of the delivery pipe. Normal water flow is discharged through the gap. If the pressure is high, it will impact the sealing head, suppressing the large water flow and preventing the cylinder from bursting, thus achieving self-pressure stabilization." In addition, the use of a pressure sensor allows for real-time monitoring of the pressure in the delivery pipe during use, and the height of the moving bar can be adjusted by the electric cylinder, which in turn squeezes the first spring to cope with water flow of different pressures, keeping the water flow stable, thereby achieving the purpose of self-pressure stabilization and convenient adjustment.

[0014] 2) During use, the filter screen can filter the liquid, preventing it from entering the self-regulating pressure assembly and affecting it. After prolonged use, the user can pull the pull head upward to move the auxiliary plate, which in turn drives the two connecting rods to rotate. The rotation of the connecting rods will move the moving plate. The moving plate slides on the auxiliary rod, causing the second spring to contract and store force. The movement of the moving plate will cause the plug to slide out of the fixed frame, releasing its self-limiting position. At this time, the user can continue to pull the pull head upward to pull out the sealing cover from the connection box. The user can then pull the filter screen out of the connection box for cleaning and replacement. Afterward, the second spring is used to reset, thus achieving the purpose of filtration and quick replacement. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example Please see Figure 1-4 An outlet self-regulating energy-saving circulating pump includes a pump body 100, a self-regulating component 200, and a rapid filtration and rapid disassembly and cleaning component 300.

[0019] Please refer to the details. Figure 1 A connection box 110 is sealed and connected to one side of the pump body 100, and a delivery pipe 120 is sealed and connected to one side of the connection box 110.

[0020] Please see Figure 1-2 The self-stabilizing component 200 includes a protective box 210 sealed and connected to the top of the delivery pipe 120. An isolation plate 220 is provided in the middle of the protective box 210. Two limiting rods 230 are provided at the top of the isolation plate 220. A moving plate 240 is slidably connected to the outer wall of the two limiting rods 230. A connector 250 is provided at the bottom of the moving plate 240. A sealing head 260 is provided through the bottom of the connector 250 through the isolation plate 220. A moving strip 270 is provided on the outer wall of the two limiting rods 230. Two first springs 280 are provided at the bottom of the moving strip 270. An electric cylinder 290 is provided at the top of the protective box 210.

[0021] In one specific embodiment, the first spring 280 facilitates the flow of liquid from the pump body 100 into the protective box 210 via the connecting box 110 and the delivery pipe 120. The water flow will press against the sealing head 260. If the water pressure is high, the sealing head 260 will be forced upwards. The force on the sealing head 260 will cause the moving plate 240 to move upwards, which in turn moves on the limiting rod 230, causing the first spring 280 to contract and rebound, suppressing the high-pressure water flow and preventing excessive pressure from causing an abnormally strong flow. When the water flow is low, the sealing head 260 will remain in its original position. The water flows smoothly out of the sealed head 260. It should be noted that "there is a large gap between the sealing head 260 and the wall of the delivery pipe 120. Normal water flow is discharged through the gap. If the pressure is high, it will impact the sealing head 260, suppressing the large water flow and preventing the cylinder from bursting, thus achieving self-pressure stabilization." In addition, a pressure sensor is used to facilitate real-time monitoring of the pressure in the delivery pipe 120 during use. The height of the moving bar 270 is adjusted by the electric cylinder 290, which in turn squeezes the first spring 280 to cope with water flow of different pressures, keeping the water flow stable and thus achieving the purpose of self-pressure stabilization and convenient adjustment.

[0022] Please see Figure 3-4 The filtration and quick-release cleaning assembly 300 includes a filter screen 310 slidably connected inside the connecting box 110. A sealing cover 320 is movably connected to the top of the connecting box 110. Two fixing pieces 330 are provided on the top of the sealing cover 320. Two auxiliary rods 340 are provided in the middle of the two fixing pieces 330. Two moving pieces 350 are slidably connected to the outer walls of the two auxiliary rods 340. A plug 360 is provided on one side of each of the two moving pieces 350. The ends of the two plugs 360 pass through the fixing pieces 330 and are inserted into the fixing brackets 370. The ends of the two fixing brackets 370 are fixedly connected to the connecting box 110.

[0023] In one specific embodiment, the provided filter screen 310 facilitates liquid filtration during use, preventing liquid from entering the self-regulating pressure assembly 200 and affecting it. During prolonged use, the user can pull the pull head 800 upwards to move the auxiliary plate 700, which in turn rotates the two connecting rods 600. The rotation of the connecting rods 600 moves the moving plate 350, which slides on the auxiliary rod 340, causing the second spring 500 to contract and store energy. The movement of the moving plate 350 causes the plug 360 to slide out of the fixing bracket 370, releasing its self-limiting position. The user can then continue pulling the pull head 800 upwards to pull the sealing cover 320 out of the connecting box 110. The user can then pull the filter screen 310 out of the connecting box 110 for cleaning and replacement, and finally reset it using the second spring 500, thus achieving the purpose of filtration and quick replacement.

[0024] Please see Figure 1 The interior of each of the two first springs 280 is slidably connected to the limit rod 230, and the bottom of each of the two first springs 280 is fixedly connected to the moving plate 240. The connecting box 110 has an external connector 400 sealed and connected to one side.

[0025] In one specific embodiment, the connection box 110 provides convenient protection for the internal parts during use, preventing damage to the internal parts due to bumps and knocks, and improving stability.

[0026] Please see Figure 4 Two second springs 500 are provided between the two movable plates 350, and the interior of the two second springs 500 is slidably connected to the auxiliary rod 340.

[0027] In one specific embodiment, the auxiliary rod 340 facilitates the movement of the movable piece 350 on the auxiliary rod 340, making it more stable during movement and avoiding wobbling.

[0028] Please see Figure 4 The tops of the two movable plates 350 are hinged with connecting rods 600, and the middle of the two connecting rods 600 is hinged with an auxiliary plate 700. The top of the auxiliary plate 700 is provided with a pull head 800.

[0029] In one specific embodiment, the provided pull head 800 allows the user to hold and pull the pull head 800 during use, enabling it to drive other parts to work, thus improving stability and increasing practicality.

[0030] Please see Figure 2-3 The output shaft end of the electric cylinder 290 passes through the protective box 210 and is fixedly connected to the moving bar 270.

[0031] In one specific embodiment, the protective box 210 provides convenient protection for the internal parts during use, preventing damage to the internal parts due to bumps or knocks, and further improving stability.

[0032] Please see Figure 1 The delivery pipe 120 has an integrated pressure sensor inside, and the protective box 210 has a controller at the top corner.

[0033] In one specific embodiment, a pressure sensor is provided to facilitate real-time monitoring of the pressure inside the delivery pipe 120 during use, so that the electric cylinder 290 can cooperate to adjust the position of the sealing head 260.

[0034] Please see Figure 1-4The pump body 100, electric cylinder 290 and pressure sensor are all electrically connected to the controller, and the controller is electrically connected to an external power supply.

[0035] In one specific embodiment, the included controller facilitates power control of the electrical equipment during use, ensuring that the equipment is powered on when needed, thus avoiding situations where power cannot be supplied when required.

[0036] In use, the first spring 280 facilitates the flow of liquid from the pump body 100 into the protective box 210 via the connecting box 110 and the delivery pipe 120. The water flow will then press against the sealing head 260. If the water pressure is high, the sealing head 260 will be forced upwards. The force on the sealing head 260 will cause the moving plate 240 to move upwards, which in turn moves on the limit rod 230, causing the first spring 280 to contract and rebound, thus suppressing the high-pressure water flow and preventing excessive pressure from causing abnormally strong water flow. In this situation, when the water flow is small, the sealing head 260 will remain in its original position, allowing the water to flow out smoothly. It should be noted that "there is a large gap between the sealing head 260 and the wall of the delivery pipe 120. Normal water flow exits through this gap. If the pressure is high, it will impact the sealing head 260, suppressing the large water flow and preventing cylinder bursting, thus achieving self-pressure stabilization." Utilizing a mechanical structure, energy saving is effectively achieved, and the use of a pressure sensor allows for real-time monitoring of the pressure within the delivery pipe 120 during use, and the pressure is controlled by an electric cylinder. 290 Adjust the height of the moving bar 270, which in turn compresses the first spring 280 to cope with water flow of different pressures, keeping the water flow stable and thus achieving self-pressure stabilization. Then, the provided filter screen 310 allows for easy filtration of the liquid during use, preventing liquid from entering the self-pressure stabilizing component 200 and affecting it. For extended use, the user can pull the pull head 800 upwards to move the auxiliary plate 700, which in turn rotates the two connecting rods 600. The rotation of the connecting rods 600 will... The movable plate 350 moves and slides on the auxiliary rod 340, which causes the second spring 500 to contract and store force. The movement of the movable plate 350 will drive the plug 360 to slide out of the fixed frame 370, releasing its own limit. Finally, the user continues to pull the pull head 800 upward to pull out the sealing cover 320 from the connecting box 110. At this time, the user pulls the filter screen 310 out of the connecting box 110 for cleaning and replacement. Then, the second spring 500 is used to reset, thereby achieving the purpose of filtration and quick replacement.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
