Description

Technical Field

[0001] This invention relates to the field of hydrocyclone sand separator technology, and in particular to a high-efficiency hydrocyclone sand separator with anti-clogging function. Background Technology

[0002] High-efficiency cyclone sand separators are solid-liquid separation devices based on the principles of fluid dynamics and filtration technology. With the increasing global emphasis on environmental protection and the increasingly stringent environmental regulations, the requirements for water quality are also becoming higher and higher. High-efficiency cyclone sand separators have emerged to meet these needs and are widely used in various fluid systems that require water purification, including sand removal from main pipelines of water supply networks in municipal and building sectors, sand removal from industrial circulating cooling water systems in industrial production, sand removal from irrigation water in agricultural and water conservancy sectors, and can also be used in special scenarios such as seawater desalination pretreatment and swimming pool circulating water treatment.

[0003] The high-efficiency cyclone sand separator works by combining centrifugal separation and filtration. When the sand-laden fluid enters the equipment shell through the tangential inlet under a certain pressure, the kinetic energy of the tangential inflow creates a high-speed rotating vortex within the shell. Due to the significant density difference between sand particles and water, the sand particles are thrown towards the shell wall under centrifugal force. Subsequently, under the combined action of gravity and water flow thrust, they settle along the wall and are eventually discharged through the bottom drain. Meanwhile, the less dense clean water gathers towards the center of the vortex, forming an upward internal vortex that flows towards the top outlet.

[0004] In existing technologies, some high-efficiency hydrocyclone sand separators suffer from blockages during use because the bottom discharge port of traditional hydrocyclone sand separators cannot be too large due to structural limitations. This leads to the accumulation of a large amount of sediment, causing blockages inside the pipe and affecting the practicality and continuity of sand removal work. Therefore, a high-efficiency hydrocyclone sand separator with anti-blockage function is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this invention provides a high-efficiency hydrocyclone sand separator with anti-clogging function, aiming to improve the problem that some high-efficiency hydrocyclone sand separators in the prior art suffer from pipe blockage caused by the accumulation of a large amount of mud and sand at the sand discharge port during use, which affects the efficiency of the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency hydrocyclone sand separator with anti-clogging function includes a support frame and a support plate. A sand removal box is fixedly connected inside the support frame. An anti-clogging mechanism is provided inside the support plate. A water outlet pipe is fixedly connected to the top of the sand removal box. A filtration mechanism is provided inside the water outlet pipe. The anti-clogging mechanism includes a fixed plate. The bottom of the fixed plate is fixedly connected to the top of the support plate. A drive assembly is provided inside the support plate. A disc is fixedly connected to the top of the drive assembly. A rotating plate is rotatably connected to the top of the disc. A connecting plate is rotatably connected inside the rotating plate. A sliding rod is rotatably connected to the outside of the connecting plate. A sliding plate is fixedly connected to the bottom of the sliding rod. A rotating rod is rotatably connected to the right end of the sliding plate. A sliding block is rotatably connected to the inside of the rotating rod. A cleaning ring is fixedly connected to the top of the sliding block.

[0008] As a further description of the above technical solution:

[0009] The filtration mechanism includes a filter screen plate, which is slidably connected to the outside of the water outlet pipe. A fixing block is fixedly connected to the top of the filter screen plate, and a support block is fixedly connected to the bottom of the filter screen plate. A limit plate is slidably connected inside the support block. A limit block is fixedly connected to the bottom right end of the water outlet pipe. Two limit shafts are fixedly connected inside the limit plate, and two limit rods are fixedly connected inside the limit block. A spring is fixedly connected inside the limit rod.

[0010] As a further description of the above technical solution:

[0011] The drive assembly includes a motor, the motor is externally fixedly connected to the inside of the support plate, the drive end of the motor is fixedly connected to a drive shaft, and the top of the drive shaft is fixedly connected to the bottom of the disc.

[0012] As a further description of the above technical solution:

[0013] The sliding rod is slidably connected to the inside of the fixed plate, the sliding plate is slidably connected to the inside of the support plate, the front end of the sand removal box is fixedly connected to the feed inlet, and the right end of the sand removal box is fixedly connected to the controller.

[0014] As a further description of the above technical solution:

[0015] The bottom of the sand removal box is fixedly connected to a sand settling pipe, the outside of the sliding block is slidably connected to the inside of the sand settling pipe, and the outside of the cleaning ring is slidably connected to the inside of the sand settling pipe.

[0016] As a further description of the above technical solution:

[0017] A slider is fixedly connected to the right end of the cleaning ring, and an impact block is fixedly connected to the right end of the sliding rod.

[0018] As a further description of the above technical solution:

[0019] The support block is externally slidably connected to the inside of the water outlet pipe, and the limiting plate is externally slidably connected to the inside of the limiting block.

[0020] As a further description of the above technical solution:

[0021] The two limiting shafts are slidably connected to the outside of the two limiting rods, and the left ends of the two limiting shafts are fixedly connected to the right ends of the two springs.

[0022] The present invention has the following beneficial effects:

[0023] 1. In this invention, the drive shaft is rotated by starting the motor, which in turn drives the disc, rotating plate, and connecting plate to rotate synchronously. The sliding rod is repeatedly slid at the limit position of the fixed plate, which in turn drives the impact block to repeatedly strike the sand settling pipe. The vibration is used to quickly loosen the accumulated sand particles and prevent them from clumping on the pipe wall. At the same time, the sliding plate is driven by the sliding rod to slide, which causes the sliding block to drive the cleaning ring to slide on the inner wall of the sand settling pipe, thereby scraping off the residual sand particles. This dual protection mechanism ensures the smooth flow of the sand discharge channel and avoids equipment downtime due to blockage, significantly improving the continuity and stability of the sand removal operation.

[0024] 2. In this invention, the filter screen plate is fixed by manually pulling the limiting plate away from the inside of the support block. At this time, the limiting shaft compresses the spring and deforms. Then, the fixing block is pulled upward to quickly remove the screen plate. By embedding the support block into the water outlet pipe and releasing the limiting plate, the spring releases its elastic force to drive the limiting plate into the inside of the support block for reset, thereby completing the fixation of the filter screen plate. This improves the secondary filtration efficiency of the filter screen plate for rising water. Compared with traditional bolt disassembly, it reduces equipment downtime for maintenance, reduces the labor intensity of operators, and further improves the efficiency of equipment use.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] A high-efficiency hydrocyclone sand separator with anti-clogging function, as described in reference Figures 1 to 3The device includes a high-efficiency cyclone sand separator with anti-clogging function, comprising a support frame 1 and a support plate 3. The support frame 1 is in contact with the ground to provide stable support for the entire device. The support plate 3 provides the installation foundation and is fixed to the outside of the support frame 1 by welding, thereby improving the support stability of the support plate 3. A sand separator 2 is fixedly connected inside the support frame 1. The sand separator 2 is the core working chamber of the cyclone sand separator, and its interior adopts a cavity structure combining conical and cylindrical shapes. When sand-laden water enters the cavity, it forms a high-speed cyclone motion within the cavity. Utilizing the density difference between sand particles and water, the sand particles move towards the cavity wall under centrifugal force and gradually sink. A feed inlet 8 is fixedly connected to the front end of the sand separator 2. The feed inlet 8 forms a certain angle with the tangent direction of the cavity of the sand separator 2, providing a conveying channel for the sand-laden water to enter the interior of the sand separator 2. A controller 9 is fixedly connected to the right end of the sand separator 2. The controller 9 uses a control system and various sensors to stably control the device.

[0040] The support plate 3 is equipped with an anti-clogging mechanism 4, which prevents sand particles from accumulating and clogging the pipes through mechanical impact and internal wall cleaning. A sand settling pipe 5 is fixedly connected to the bottom of the sand removal box 2, providing a conveying channel for the discharge of separated sand particles. A water outlet pipe 6 is fixedly connected to the top of the sand removal box 2, providing an output channel for the purified water flow. A filter mechanism 7 is installed inside the water outlet pipe 6, which performs secondary filtration on fine sand particles in the rising flow, further improving the purity of the effluent. The anti-clogging mechanism 4 includes a fixing plate 41, the bottom of which is fixedly connected to the top of the support plate 3. The support plate 3 provides support for the fixing plate 41, enhancing its stability. A drive assembly 42 is installed inside the support plate 3, providing fixation to prevent the drive assembly 42 from shaking during operation and ensuring its operational stability. The drive assembly 42 includes a motor 421, which is externally and fixedly connected to the inside of the support plate 3. The support plate 3 provides support for the motor 421, preventing it from shifting during operation and improving its operational stability. A drive shaft 422 is fixedly connected to the drive end of the motor 421. Starting the motor 421 provides driving force for the rotation of the drive shaft 422, thereby ensuring the stable rotation of the drive shaft 422.

[0041] A disk 43 is fixedly connected to the top of the drive assembly 42, and the top of the drive shaft 422 is fixedly connected to the bottom of the disk 43. The rotation of the drive shaft 422 drives the disk 43 to rotate synchronously. A rotating plate 44 is rotatably connected to the top of the disk 43. The disk 43 is connected to the rotating plate 44 via a shaft, and the rotation of the disk 43 drives the rotating plate 44 to rotate stably. A connecting plate 45 is rotatably connected inside the rotating plate 44. The rotating plate 44 is connected to the connecting plate 45 via a shaft, and the rotation of the rotating plate 44 drives the connecting plate 45 to rotate. A sliding rod 46 is rotatably connected to the outside of the connecting plate 45, and the rotation of the connecting plate 45 drives the sliding rod 46 to rotate. An impact block is fixedly connected to the right end of the sliding rod 46. The outside of the sliding rod 46 is slidably connected to the inside of the fixed plate 41. Through the limiting of the fixed plate 41, the sliding rod 46 converts the rotational force into sliding force, which in turn drives the impact block to impact the sand settling pipe 5, causing the sand settling pipe 5 to vibrate. This loosens the sand particles accumulated on the inner wall of the sand settling pipe 5, preventing the sand particles from caking and clogging the pipe. A sliding plate 47 is fixedly connected to the bottom of the sliding rod 46. The outside of the sliding plate 47 is slidably connected to the inside of the support plate 3. The support plate 3 provides guidance for the sliding of the sliding plate 47. The sliding of the sliding rod 46 drives the sliding plate 47 to slide stably inside the support plate 3, thereby ensuring the sliding stability of the sliding plate 47.

[0042] A rotating rod 48 is rotatably connected to the right end of the sliding plate 47. The sliding plate 47 is connected to the rotating rod 48 via a shaft, and the sliding of the sliding plate 47 drives the rotating rod 48 to rotate. A sliding block 49 is rotatably connected inside the rotating rod 48, and the sliding block 49 is slidably connected to the inside of the sand settling pipe 5. The sand settling pipe 5 provides guidance for the sliding of the sliding block 49. The rotation of the rotating rod 48 drives the sliding block 49 to slide stably inside the sand settling pipe 5. A cleaning ring 410 is fixedly connected to the top of the sliding block 49, and the sliding of the sliding block 49 causes the cleaning ring 410 to move. A slider is fixedly connected to the right end of the cleaning ring 410. The slider provides a limit for the sliding of the cleaning ring 410, preventing the cleaning ring 410 from deviating during the sliding process and improving the sliding stability of the cleaning ring 410. The cleaning ring 410 is externally slidably connected to the inside of the sand settling pipe 5. The sand settling pipe 5 provides guidance for the sliding of the cleaning ring 410. The inner wall of the sand settling pipe 5 is cleaned by the sliding of the cleaning ring 410, which improves the cleaning effect of the inner wall and further prevents sand particles from accumulating and clogging.

[0043] Specifically, the controller 9 controls the stable operation of the equipment. Sand-laden water flows into the sand removal box 2 through the feed inlet 8. The sand removal box 2 uses a conical and cylindrical cavity structure, causing the sand particles to move towards the cavity wall under centrifugal force and gradually sink. The separated sand particles are discharged through the settling pipe 5, and the purified water is output through the outlet pipe 6. At this point, the motor 421 drives the drive shaft 422 to rotate, which in turn drives the disc 43 to rotate. The rotation of the disc 43 drives the rotating plate 44 and the connecting plate 45 to rotate, while the fixed plate 4... Under the limit of 1, the connecting plate 45 drives the sliding rod 46 to slide inside the fixed plate 41, causing the sliding rod 46 to drive the impact block to strike the sand settling pipe 5, causing the sand settling pipe 5 to vibrate, preventing sand particles from accumulating and clogging the pipe. At the same time, it drives the sliding plate 47 to slide inside the support plate 3, thereby driving the rotating rod 48 to rotate. The rotation of the rotating rod 48 drives the sliding block 49 to slide inside the sand settling pipe 5, thereby driving the cleaning ring 410 to slide inside the sand settling pipe 5, thus cleaning the inner wall of the sand settling pipe 5 and further preventing sand particles from accumulating and clogging.

[0044] Reference Figure 1 , Figure 2 and Figure 4 The filtration mechanism 7 includes a filter screen 72, which is used to intercept fine sand particles that cannot be removed by cyclone separation, thereby improving the cleanliness of the water. The filter screen 72 is externally slidably connected to the inside of the outlet pipe 6, which guides the sliding of the filter screen 72. Sliding the filter screen 72 facilitates replacement and improves maintenance efficiency. A fixing block 71 is fixedly connected to the top of the filter screen 72; manually pulling the fixing block 71 causes the filter screen 72 to slide away from the inside of the outlet pipe 6. A support block 73 is fixedly connected to the bottom of the filter screen 72, providing a limit to the sliding of the filter screen 72 and preventing it from shifting during sliding. The support block 73 is externally slidably connected to the inside of the outlet pipe 6, which guides the sliding of the support block 73, thereby improving its sliding stability. A limiting plate 74 is slidably connected inside the support block 73. The support block 73 provides guidance for the sliding of the limiting plate 74, and the limiting plate 74 limits the support block 73 by sliding. A limiting block 75 is fixedly connected to the bottom right end of the water outlet pipe 6. The water outlet pipe 6 is connected to the limiting block 75 by welding, thereby improving the load-bearing stability of the limiting block 75.

[0045] The limiting plate 74 is externally slidably connected to the inside of the limiting block 75. The limiting block 75 provides guidance for the sliding of the limiting plate 74, thereby improving the sliding stability of the limiting plate 74. Two limiting shafts 76 are fixedly connected internally to the limiting plate 74. The sliding of the limiting plate 74 drives the two limiting shafts 76 to move synchronously. Two limiting rods 77 are fixedly connected internally to the limiting block 75. The limiting block 75 provides fixation for the two limiting rods 77, thereby improving the stability of the limiting rods 77. The two limiting shafts 76 are externally slidably connected to the inside of the two limiting rods 77. The sliding of the limiting plate 74 drives the two limiting shafts 76 to slide within the two limiting rods 77, thereby causing the limiting plate 74 to slide away from the inside of the support block 73. A spring 78 is fixedly connected inside the limiting rod 77. The left ends of the two limiting shafts 76 are fixedly connected to the right ends of the two springs 78 respectively. By sliding the limiting plate 74, the limiting shafts 76 are driven to compress the springs 78, causing the springs 78 to deform under force. The springs 78 release the elastic force, causing the limiting shafts 76 to drive the limiting plate 74 to reset and embed into the support block 73.

[0046] Specifically, the water is initially purified and transported through the outlet pipe 6. The filter screen plate 72 performs secondary filtration on the fine sand particles in the upward flow, thereby further improving the purity of the effluent. When replacing the filter screen plate 72, the filter screen plate 72 is slid away from the interior of the outlet pipe 6 by manually pulling the fixing block 71. At this time, by pulling the limiting plate 74 to the left, the limiting plate 74 drives the two limiting shafts 76 to compress the two springs 78, causing the two springs 78 to deform under force, thereby allowing the limiting plate 74 to slide away from the interior of the support block 73, completing the replacement of the filter screen plate 72. After the filter screen plate 72 is embedded into the interior of the outlet pipe 6, the limiting plate 74 is released, and the springs 78 release their elasticity, causing the limiting plate 74 to be embedded into the interior of the support block 73, thereby completing the quick installation of the filter screen plate 72.

[0047] The implementation principle of this application embodiment is as follows: The operator starts the equipment through the controller 9. The sand-containing water flows into the cavity through the feed inlet 8 at a specific angle to the tangent of the sand removal box 2. Since the sand removal box 2 adopts a combination of conical and cylindrical cavity structure, the water will form a high-speed swirling motion along the cavity wall after entering. Under the action of centrifugal force, sand particles with a density much greater than that of water are thrown towards the cavity wall and then slide down the cavity wall, gradually separating from the water, completing the initial sand removal. The separated sand particles enter the bottom sedimentation pipe 5, waiting to be discharged, while the initially purified water rises along the center of the cavity and finally flows to the top outlet pipe 6. During the sand particle discharge process, the drive shaft 422 is driven to rotate by starting the motor 421, thereby causing the top disc 43 to rotate synchronously. 43 drives the rotating plate 44 and connecting plate 45 to move sequentially through the shaft connection. Since the sliding rod 46 is limited by the fixed plate 41, the sliding rod 46 converts the rotational force into horizontal reciprocating sliding, which drives the impact block at its right end to repeatedly strike the outer wall of the sand settling pipe 5, causing the sand settling pipe 5 to generate high-frequency vibration, which loosens the sand particles accumulated on the inner wall and prevents them from clumping and blocking. At the same time, the sliding rod 46 drives the sliding plate 47 to slide synchronously inside the support plate 3. The sliding plate 47 drives the rotating rod 48 to rotate through the shaft, which in turn pushes the sliding block 49 to slide up and down inside the sand settling pipe 5. The cleaning ring 410 at the top of the sliding block 49 slides on the inner wall of the sand settling pipe 5 to scrape off the residual sand particles and further ensure that the sand discharge channel is unobstructed.

[0048] After initial purification, the water flows along the outlet pipe 6 and passes through the filter screen 72. The filter screen 72 is used to intercept fine sand particles that were not separated and removed after centrifugation, thereby reducing the turbidity of the effluent and meeting the subsequent water demand. When the filter screen 72 needs to be replaced, the operator manually pulls the limiting plate 74 to the left, causing the limiting plate 74 to drive the two internal limiting shafts 76 to slide along the inside of the limiting rod 77 and compress the spring 78 to deform until the limiting plate 74 is completely disengaged from the slot of the support block 73. The fixing block 71 at the top of the filter screen 72 is pulled upward, causing the screen and the bottom support block 73 to slide out along the guide groove of the outlet pipe 6, completing the disassembly of the filter screen 72. By embedding the support block 73 of the new filter screen 72 into the interior of the outlet pipe 6, the limiting plate 74 is released. The spring 78 releases the elastic force, pushing the limiting shaft 76 to reset the limiting plate 74, thereby allowing the limiting plate 74 to re-embed into the slot of the support block 73, achieving quick fixation of the new screen.
