Description

Technical Field

[0001] The utility model relates to the field of pump bodies, in particular to an energy-saving pump for a water circulation system. Background Art

[0002] With the continuous advancement of environmental protection and energy-saving technologies, more and more companies have established water circulation systems in their factories to collect rainwater for daily production. The water in the water circulation system is transported by water pumps.

[0003] The water consumption of the water circulation system is uncertain in different time periods, which also causes the water pressure in the water circulation system to fluctuate back and forth easily, making the water inlet pressure at the water pump inlet unstable. This makes it take longer for the water pump to transport the same volume of liquid, thereby consuming more energy and reducing work efficiency. Utility Model Content

[0004] The present application provides an energy-saving pump for a water circulation system, which is provided with a flow stabilizing structure to ensure that the water inlet pressure of the pump body is stable, thereby reducing the working time of the pump body and achieving energy-saving effect.

[0005] The energy-saving pump for a water circulation system provided in this application adopts the following technical solution:

[0006] The cam is provided with a plurality of through-holes, and one end of the two fixing rods is connected to the side wall of the annular groove, and the other end of the two fixing rods is connected to the fixing plate. A first flow hole and a plurality of second flow holes are provided on the flow control plate, and the plurality of second flow holes are arranged around the first flow hole. The two springs are respectively mounted on the two fixing rods and press the flow control plate against the end surface of the annular groove away from the pump body. The fixed plate is provided with a flow control column for blocking the first flow hole. The end of the flow control column away from the pump body is in the form of a cone, and the flow control column is located on the movement path of the flow control plate.

[0007] By adopting the above technical solution, when the pump body transports water, the water will first flow into the flow stabilizing tube, then collide with the flow control plate and pass through the flow control plate from the first flow hole, and then flow into the pump body through multiple through holes. When the water flow collides with the flow control plate, the water flow will push the flow control plate to slide toward the side of the fixed disk. When the flow control plate slides, the two springs will be compressed, and at the same time, the conical end of the flow control column will be inserted into the first flow hole. When the pressure of the water flow entering the flow stabilizing tube increases, the thrust of the water flow on the flow control plate will increase, and the flow control plate will slide further toward the fixed disk, so that the area of the first flow hole blocked by the flow control column will increase, making the water flow through the first flow hole smaller, thereby reducing the pressure of the water flow through the flow control plate, so that the pressure will not be too high when the water flows into the pump body. If the water pressure entering the flow stabilizing tube decreases, the thrust of the water on the flow control plate will also decrease. The flow control plate, under the action of the spring, will slide away from the fixed plate, reducing the area of the first flow hole blocked by the flow control column. This reduces the area of the first flow hole blocked by the flow control column, increasing the water flow through the first flow hole, thereby increasing the pressure of the water flowing through the flow control plate. The flow control plate and the flow control column cooperate to dynamically adjust the pressure of the water entering the pump body, so that the water inlet pressure at the pump body does not fluctuate, reducing the pump body's operating time and thus reducing the pump body load, thereby achieving energy saving effects.

[0008] Preferably, filter screens are provided in the plurality of through holes, and the plurality of filter screens are flush with a side of the fixing plate away from the pump body.

[0009] By adopting the above technical solution, a filter is set to intercept impurities in the water flow, preventing the impurities from entering the pump body and damaging the impeller of the pump body.

[0010] Preferably, a mounting post is provided on the fixed disk, the flow control post is rotatably connected to the mounting post, and a scraper for scraping impurities on the filter screen is provided on the outer wall of the flow control post.

[0011] By adopting the above technical solution, when maintaining the pump body, the hand passes through the first retention hole and then holds the flow control column and rotates the flow control column, so that the scraper rotates to scrape off impurities attached to the filter screen, thereby ensuring the filtering performance of the filter screen and the water intake of the pump body.

[0012] Preferably, the pump body is also provided with a control component for limiting the rotation of the flow control column relative to the mounting column, the control component includes a first slot opened on the end face of the flow control column away from the pump body, a second slot opened on the mounting column and connected to the first slot, and a limit column inserted in the first slot and the second slot.

[0013] By adopting the above technical solution, the rotation of the flow control column is limited by the cooperation of the control component when the pump body is in use. Otherwise, when the pump body is started, the water flow will drive the flow control column to rotate, causing the scraper to rotate and causing rapid wear of the scraper. At the same time, the rotation of the scraper will generate vortexes, which will affect the efficiency of water flow through the filter, thereby affecting the stability of the water inlet pressure of the pump body.

[0014] Preferably, two gripping rods are provided on one end of the limiting column away from the pump body, and accommodating grooves for accommodating the gripping rods are provided on both side walls of the first slot.

[0015] By adopting the above technical solution, when cleaning the protective net, the limit column is pulled out of the first slot, and then the limit column is rotated through the two grips to rotate the flow control column. This is more labor-saving than directly holding the flow control column and applying force to make it rotate.

[0016] Preferably, a first threaded hole is provided on the side of the limiting column away from the pump body, a second threaded hole connected to the first threaded hole is provided on the bottom wall of the second slot, and a bolt is provided on the limiting column, and the bolt is threadedly connected in the first threaded hole and the second threaded hole.

[0017] By adopting the above technical solution, when the pump body is in use, the bolt and the first and second threaded holes can further limit the rotation of the flow control column. When cleaning the protective net, the bolt is rotated to the second threaded hole with a tool. At this time, the limit column can be pulled out of the first slot by pulling out the bolt, making it easier to remove the limit column.

[0018] Preferably, a water injection hole is provided on the side wall of the annular groove, and the water injection hole connects the inner cavity of the flow stabilizing tube and the outside world. One side opening of the water injection hole is arranged toward the fixed disk, and a one-way valve is provided in the water injection hole to only allow water to flow from the outside world into the flow stabilizing tube.

[0019] By adopting the above technical solution, when cleaning the protective net, water is injected into the flow stabilizing pipe through the water injection hole using a water pipe, and the scraper is used to better clean the impurities attached to the surface of the filter net.

[0020] Preferably, a sewage outlet is provided on the side wall of the chute, and the sewage outlet is located below the water injection hole. The sewage outlet connects the inner cavity of the flow stabilizing tube and the outside world. The sewage outlet is connected to a sewage pipe, and a plug cover is provided on the end of the sewage pipe away from the flow stabilizing tube. The plug cover is threadedly connected to the outer wall of the sewage pipe and seals the pipe mouth of the sewage pipe.

[0021] By adopting the above technical solution, the impurities cleaned on the filter net can be quickly discharged from the flow stabilizing pipe together with the sewage through the sewage pipe.

[0022] The technical effects of this utility model are mainly reflected in the following aspects:

[0023] 1. The utility model dynamically adjusts the pressure of the water flow entering the pump body through the cooperation of the flow control plate and the flow control column, so that the water pressure will not fluctuate up and down, reducing the working time of the pump body, thereby reducing the pump body load and achieving energy saving effect;

[0024] 2. The utility model rotates the flow control column to rotate the scraper to clean the filter;

[0025] 3. The utility model sets a bolt to further limit the rotation of the flow control column when the pump body is in use, and it is more labor-saving to pull out the limit column when cleaning the protective net. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0031] This embodiment of an energy-saving pump for a water circulation system includes a pump body 1. A flow stabilizing tube 2 is fixed to the water inlet of the pump body 1. An annular groove 21 is defined on the inner wall of the flow stabilizing tube 2. A fixed disc 22 is fixed to the sidewall of the annular groove 21, sealing the flow stabilizing tube 2. The fixed disc 22 has multiple through-holes 26, each of which is fitted with a filter screen 28. The filter screens 28 are flush with the side of the fixed disc 22 facing away from the pump body 1.

[0032] Two fixing rods 23 are also provided in the annular groove 21. The two fixing rods 23 are located on the side of the fixing plate 22 away from the pump body 1. The two fixing rods 23 are respectively located above and below the flow stabilizing tube 2. One end of the two fixing rods 23 is fixedly connected to the end surface of the annular groove 21 away from the pump body 1, and the other end of the two fixing rods 23 is fixedly connected to the side of the fixing plate 22 away from the pump body 1. The axes of the two fixing rods 23 are parallel to the axis of the flow stabilizing tube 2.

[0033] A flow control plate 24 is also provided within the annular groove 21. The upper and lower ends of the flow control plate 24 are slidably connected to two fixed rods 23 along the axis of the flow stabilizing tube 2. Both fixed rods 23 are sleeved with springs 25. One end of each spring 25 contacts the side of the fixed plate 22 facing away from the pump body 1, while the other end of each spring 25 contacts the flow control plate 24. In the absence of external force, the two springs 25 press the flow control plate 24 against the end surface of the annular groove 21 facing away from the pump body 1.

[0034] A first flow hole 27 is defined in the center of the flow control plate 24, along the axis of the flow stabilizing tube 2. A mounting post 4 is fixed to the surface of the fixed disk 22 facing the flow control plate 24. A flow control post 3 is rotatably connected to the mounting post 4, sealing the first flow hole 27. The end of the flow control post 3, facing away from the pump body 1, is formed into a circular cone and positioned in the motion path of the flow control plate 24. Initially, the flow control post 3 does not extend into the first flow hole 27.

[0035] When pump body 1 delivers water, the water first flows into flow stabilizing tube 2, then collides with flow control plate 24 and passes through first flow hole 27 and multiple second flow holes in flow control plate 24 before flowing into pump body 1 through multiple through-holes 26. When the water collides with flow control plate 24, it pushes flow control plate 24 toward fixed plate 22. This sliding of flow control plate 24 compresses two springs 25, and simultaneously the frustum-shaped end of flow control column 3 is inserted into first flow hole 27.

[0036] When the pressure of the water flow entering the flow stabilizing tube 2 increases, the thrust of the water flow on the flow control plate 24 increases, and the flow control plate 24 will slide further toward the fixed disk 22, so that the area of the first flow hole 27 blocked by the flow control column 3 becomes larger, and the water flow passing through the first flow hole 27 becomes smaller, thereby reducing the pressure of the water flow passing through the flow control plate 24, so that the pressure will not be too high when the water flows into the pump body 1.

[0037] When the water pressure of the water flow entering the flow stabilizing tube 2 becomes smaller, the thrust of the water flow on the flow control plate 24 will become smaller. Under the action of the spring 25, the flow control plate 24 will slide to the side away from the fixed disk 22, so that the area of the first flow hole 27 blocked by the flow control column 3 is small. The area of the first flow hole 27 blocked by the flow control column 3 becomes smaller, and the water flow passing through the first flow hole 27 becomes larger, thereby increasing the pressure of the water flow passing through the flow control plate 24.

[0038] The pressure of the water flow entering the pump body 1 is dynamically adjusted by the cooperation of the flow control plate 24 and the flow control column 3, so that the water inlet pressure of the pump body 1 will not fluctuate up and down, reducing the working time of the pump body 1, thereby reducing the load of the pump body 1 and achieving energy saving effect.

[0039] A scraper 32 is fixedly attached to the outer wall of the flow control post 3, for scraping impurities off the filter screen 28. A control assembly 5 is also provided within the pump body 1 for limiting the rotation of the flow control post 3 relative to the mounting post 4. This control assembly 5 comprises a first slot 51, defined along the axis of the flow stabilizing tube 2, on the end face of the flow control post 3 facing away from the pump body 1; a second slot 52, defined along the axis of the flow stabilizing tube 2, on the mounting post 4 and communicating with the first slot 51; and a limiting post 53, inserted into both the first and second slots 51, 52.

[0040] The cooperation between the limiting column 53 and the first slot 51 and the second slot 52 ensures that the flow control column 3 will not rotate when the pump body 1 is in use. Otherwise, when the pump body 1 is started, the water flow will drive the flow control column 3 to rotate, causing the scraper 32 to rotate and causing rapid wear of the scraper 32. At the same time, the rotation of the scraper 32 will generate eddy currents, which will affect the efficiency of the water flow through the filter 28, thereby affecting the stability of the water inlet pressure of the pump body 1.

[0041] Two gripping rods 6 are provided on the end of the limiting post 53 away from the pump body 1. Receiving slots 31 for accommodating the gripping rods 6 are defined on both sidewalls of the first slot 51. A first threaded hole 71 is defined on the side of the limiting post 53 away from the pump body 1. A second threaded hole 72 communicating with the first threaded hole 71 is defined on the bottom wall of the second slot 52. A bolt 73 is provided on the limiting post 53 and threadedly engages within the first and second threaded holes 71 and 72.

[0042] A water injection hole 81 is provided on the top side wall of the annular groove 21, which connects the inner cavity of the flow stabilizing tube 2 and the outside world. One side opening of the water injection hole 81 is set toward the fixed disk 22. A one-way valve 82 is provided in the water injection hole 81 to only allow water to flow from the outside into the flow stabilizing tube 2.

[0043] A sewage outlet 91 is provided on the bottom side wall of the chute, and the sewage outlet 91 is located below the water injection hole 81. The sewage outlet 91 connects the inner cavity of the flow stabilizing tube 2 and the outside world. A sewage pipe 92 is connected to the sewage outlet 91. A plug cover 93 is provided on the end of the sewage pipe 92 away from the flow stabilizing tube 2. The plug cover 93 is threadedly connected to the outer wall of the sewage pipe 92 and seals the pipe mouth of the sewage pipe 92.

[0044] To clean the filter 28, first remove the plug 93 from the drain pipe 92. Then, use a water pipe to inject clean water mixed with detergent into the flow stabilizing tube 2 through the water inlet 81. This water flushes the fixed plate 22, washing away some impurities on the filter 28 and draining through the drain pipe 92. Any impurities firmly adhering to the filter 28 will be softened by the clean water, making them easier to remove by the scraper 32.

[0045] Then, the bolt 73 is screwed into the second threaded hole 72 by a tool such as a screwdriver. At this time, the limiting column 53 can be pulled out from the first slot 51 by pulling out the bolt 73, making it easier to pull out the limiting column 53.

[0046] After the limiting post 53 is pulled out of the first slot 51, the limiting post 53 is rotated by the two handles 6, thereby rotating the flow control post 3 with less effort. At this time, the flow control post 3 will also rotate with the scraper 32. The scraper 32 rotates 360 degrees to scrape off impurities attached to the filter screen 28, allowing the impurities and clean water to be discharged from the flow stabilizing pipe 2 through the drain pipe 92.

[0047] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
