Description

Technical Field

[0001] This utility model relates to the field of ejector technology, specifically a self-rotating ejector with a cleaning function. Background Technology

[0002] The self-rotating ejector itself is not equipped with a power unit. It connects to the existing pump system in the tank farm and works in conjunction with an external circulating pump via pipelines. The pump draws oil out of the tank and uses the pressure generated by the pump to return the oil to the tank, where it is then ejected outwards by the self-rotating ejector. This ejector converts the pressure applied to the liquid by the pump into a liquid jet, rotating slowly at a speed of 12-25 revolutions per minute. This achieves all-around spraying and blending of the medium in the storage tank, effectively preventing media sedimentation, ensuring no dead zones in the tank, and providing a fast blending speed, thus shortening the overall blending time and reducing operating energy consumption.

[0003] However, at the beginning and end of each ejector operation, due to the relatively low liquid pressure and flow rate, larger particles in the ejected liquid are more likely to accumulate and condense. Over time, this can lead to blockages at the nozzle and inside the ejector, affecting its normal operating performance. Therefore, to prevent impurities from entering the ejector and causing blockages, affecting the spraying effect and normal equipment operation, ejectors typically use filter plates or screens to filter the ejected liquid. However, after a period of use, these filter plates or screens often become clogged, hindering the normal flow of liquid. Traditional similar equipment often lacks an effective cleaning structure, making it inconvenient to use and impractical, failing to meet actual production needs. Summary of the Invention

[0004] The purpose of this invention is to provide a self-rotating jet with a cleaning function to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-rotating sprayer with cleaning function, comprising a base, a rotating part, a spray chamber, and a spray head. The spray chamber is rotatably connected to the base via the rotating part. The spray head is symmetrically arranged on the outside of the spray chamber. A rotating shaft is rotatably installed inside the base and the rotating part, and an impeller is connected to the lower end of the rotating shaft inside the base. Two filter plates are sequentially sleeved on the outside of the rotating shaft. A cleaning mechanism is provided below each of the two filter plates, and the cleaning mechanism is connected to the rotating shaft. The cleaning mechanism includes a cleaning seat, which is fixedly connected to the rotating shaft. Two rotating rods are provided below the cleaning seat, and a cleaning brush is connected to the lower end of the rotating rods via a fixing component.

[0006] Furthermore, the cleaning mechanism also includes a crankshaft, which is rotatably mounted inside the cleaning seat on one side. A gear is sleeved on the lower outer side of the crankshaft. A through groove adapted to the gear is opened at one end of the cleaning seat. Several toothed grooves meshing with the gear are opened on the inner wall of the base. A connecting piece is rotatably connected to the concave part of the crankshaft. A slider is rotatably sleeved on the upper outer side of the rotating rod, and the slider is slidably mounted inside the cleaning seat. The slider on the right side is connected to the connecting piece through a connecting rod. The two sliders are connected by a fixed rod. A guide groove adapted to the rotating rod is opened on the side of the cleaning seat near the filter plate, so that the liquid delivered by the pump drives the impeller to rotate the rotating shaft. Through transmission, the cleaning brush reciprocates to clean the filter plate on one side, removing most of the blockage and preventing the filter plate from being blocked and affecting the flow of liquid.

[0007] Furthermore, a second gear is fitted onto the upper end of the rotating rod, and a rack meshes with one side of the second gear, with the rack fixedly connected to the cleaning seat, so that the cleaning brush can rotate in both directions, thereby improving the cleaning effect.

[0008] Furthermore, the fixing component includes a fixing sleeve, which is fixedly installed on the top of the cleaning brush and sleeved on the outer side of the lower end of the rotating rod. The outer wall of the lower end of the rotating rod has symmetrically opened chambers. The chambers are provided with springs and protrusions, and the protrusions are located on the side closer to the fixing sleeve. One end of the protrusion penetrates through a through hole opened in the side wall of the fixing sleeve to facilitate the disassembly and installation of the cleaning brush and make it easy to disassemble and replace it.

[0009] Furthermore, the crankshaft and the rotating rod are rotatably connected to the cleaning seat and the slider respectively via bearings. The upper end of the rotating rod is in contact with the inner wall of the cleaning seat on the side away from the cleaning brush. The two filter plates are a coarse filter plate and a fine filter plate, respectively, so as to filter particles of different sizes.

[0010] Furthermore, the two ends of the spring are fixedly connected to the protrusion and the inner wall of the cavity, respectively. One end of the protrusion has a hemispherical structure so that when the cleaning brush is disassembled, the end of the protrusion can be squeezed by the fixing sleeve to retract it into the cavity.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model utilizes a cleaning mechanism that leverages the power generated by the liquid flow driving the impeller to rotate the shaft, thereby driving the cleaning mechanism to rotate synchronously. This, in turn, drives gear one to rotate, which, through transmission, continuously drives the cleaning brush to rotate around the shaft and reciprocate. In conjunction with gear two and the rack, the cleaning brush can rotate in both directions, thus improving the cleaning effect on the filter plate. This allows the filter plate to be cleaned of most of the blockages, preventing it from becoming clogged and affecting the filtration effect. It is convenient to use and has greater practicality.

[0013] 2. This utility model uses a fixing component to facilitate the disassembly, replacement, and installation of damaged cleaning brushes. Attached Figure Description

[0020] 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.

[0021] Example: Figure 1 - Figure 5As shown, this utility model provides a technical solution: a self-rotating sprayer with cleaning function, including a base 1, a rotating part 2, a spray chamber 3, and a spray head 4. The spray chamber 3 is rotatably connected to the base 1 through the rotating part 2. The spray head 4 is symmetrically arranged on the outside of the spray chamber 3. A rotating shaft 6 is rotatably installed inside the base 1 and the rotating part 2. An impeller 5 is connected to the lower end of the rotating shaft 6 inside the base 1. Two filter plates 7 are sequentially sleeved on the outside of the rotating shaft 6. A cleaning mechanism 8 is provided below each of the two filter plates 7. The cleaning mechanism 8 is connected to the rotating shaft 6. The cleaning mechanism 8 includes a cleaning seat 9, which is fixedly connected to the rotating shaft 6. Two rotating rods 15 are provided below the cleaning seat 9, and a cleaning brush 19 is connected to the lower end of the rotating rod 15 through a fixing component. In this example, the cleaning mechanism 8 also includes a crankshaft 10, which is rotatably mounted inside the cleaning seat 9. A gear 11 is sleeved on the lower outer side of the crankshaft 10. A through groove adapted to the gear 11 is opened at one end of the cleaning seat 9. Several toothed grooves 23 that mesh with the gear 11 are opened on the inner wall of the base 1. A connecting piece 12 is rotatably connected to the concave part of the crankshaft 10. A slider 14 is rotatably sleeved on the upper outer side of the rotating rod 15, and the slider 14 is slidably mounted inside the cleaning seat 9. The slider 14 on the right side is hinged to the connecting piece 12 through the connecting rod 13. The two sliders 14 are connected by a fixing rod 16. A guide groove 24 adapted to the rotating rod 15 is opened on the side of the cleaning seat 9 near the filter plate 7, so that the impeller 5 driven by the pump can drive the rotating shaft 6 to rotate. The cleaning brush 19 is driven to reciprocate to clean the filter plate 7 on one side, removing most of the blockage and preventing the filter plate 7 from being blocked and affecting the flow of liquid. In this example, a gear 17 is fitted on the upper end of the rotating rod 15. A rack 18 is meshed on one side of the gear 17, and the rack 18 is fixedly connected to the cleaning seat 9 so that the cleaning brush 19 can rotate in both directions to improve the cleaning effect.

[0022] In this example, the fixing assembly includes a fixing sleeve 20, which is fixedly installed on the top of the cleaning brush 19 and sleeved on the outer side of the lower end of the rotating rod 15. The outer wall of the lower end of the rotating rod 15 has symmetrically formed chambers 25, each containing a spring 22 and a protrusion 21. The protrusion 21 is located near the fixing sleeve 20, and one end of the protrusion 21 penetrates a through hole in the side wall of the fixing sleeve 20 to facilitate the disassembly and installation of the cleaning brush 19, making it easy to remove and replace. In this example, the crankshaft 10 and the rotating rod 15 are rotatably connected to the cleaning seat 9 and the slider 14 respectively via bearings. The upper end of the rotating rod 15 is in contact with the inner wall of the cleaning seat 9 on the side away from the cleaning brush 19. The two filter plates 7 are a coarse filter plate and a fine filter plate, respectively, to filter particles of different sizes. In this example, the two ends of the spring 22 are fixedly connected to the protrusion 21 and the inner wall of the chamber 25, respectively. One end of the protrusion 21 is a hemispherical structure so that when the cleaning brush 19 is disassembled, the end of the protrusion 21 can be squeezed by the fixing sleeve 20 to retract into the chamber 25.

[0023] The working principle of this utility model is as follows: During use, the base 1 is connected to the circulation pipeline inside the storage tank. When liquid enters the base 1 and flows through the rotating part 2, it is guided into the spray chamber 3 and sprayed out from the spray head 4 connected to the spray chamber 3. The recoil force of the sprayed liquid is transmitted to the rotating part 2, causing it to rotate at a constant speed. This converts the pressure energy in the circulation pipeline inside the storage tank into a jet, causing the spray chamber 3 to rotate slowly with the rotating part 2. During operation, the flowing liquid drives the impeller 5, which in turn drives the rotating shaft 6 to rotate. The rotating shaft 6 then drives the cleaning mechanism 8 to rotate synchronously. Simultaneously, the cleaning seat 9 in the cleaning mechanism 8 rotates with the rotating shaft 6. Driven by gear 11, which meshes with the toothed groove of gear 11, the crankshaft 10 is driven to rotate. The crankshaft 10 then drives the connecting rod 13 to push and pull the connecting rod 13, causing the connecting rod 13 to drive the connected slider 14. This, in turn, works with the fixed rod 16 to make the two sliders 14 reciprocate left and right. At the same time, the sliders 14 drive the rotating rod 15 and the connected cleaning brush 19 to move synchronously, allowing the cleaning brush 19 to clean the filter plate 7 while revolving around the rotating shaft 6. The rotating rod 15, while moving left and right, drives the connected gear 17 to move. The rack 18 meshing with gear 17 then drives the gear... The second component 17 drives the rotating rod 15 to rotate in both directions, causing the cleaning brush 19 to rotate in both directions as well. This improves the cleaning effect on the filter plate 7, enabling it to remove most of the filtered material, preventing clogging of the filter plate 7, and ensuring smooth liquid flow. It also provides a self-cleaning function and is easy to use. If a cleaning brush 19 is damaged and needs to be replaced, simply press the protrusion 21 simultaneously, causing it to move into the chamber 25 and compress the spring 22 until the outermost end of the protrusion 21 aligns with the side wall of the fixing sleeve 20. Then, pull down the cleaning brush 19 to move the fixing sleeve 20, causing the inner wall of the through hole in the fixing sleeve 20 to press against the curved surface of the hemispherical end of the protrusion 21, thus cleaning the filter plate. The protruding post 21 continues to move into the chamber 25 until it is completely inside the fixing sleeve 20. Then the cleaning brush 19 can be disassembled and replaced. During installation, repeat the above steps: press the protruding post 21 into the chamber 25, then put the fixing sleeve 20 on the outside of the rotating rod 15 and gradually push it up. After the inner wall of the fixing sleeve 20 squeezes the protruding post 21, release the pressure on the protruding post 21. Continue to push the fixing sleeve 20 up until the through hole on the fixing sleeve 20 corresponds to the protruding post 21. Then, under the elastic force of the spring 22, the protruding post 21 is driven to reset and pass through the through hole, realizing the connection between the rotating rod 15 and the fixing sleeve 20, and completing the installation of the cleaning brush 19.
