Description

Technical Field

[0001] This utility model belongs to the technical field of bleaching powder production equipment, and in particular, it is a circulating water pump used in bleaching powder production. Background Technology

[0002] In the production of bleaching powder, circulating water pumps play a crucial role. They are responsible for circulating the reaction liquid between different production stages to ensure the continuity and stability of the production process. Traditional circulating water pumps used in bleaching powder production can meet basic usage requirements, but their weak backflow prevention means that when the liquid flows back, it impacts the impeller, subjecting it to reverse impact forces. Over time, this can cause the impeller blades to crack, deform, or even break. It also accelerates wear at the connection between the impeller and the shaft, leading to loosening of the connection.

[0003] A search revealed Chinese patent document (authorization announcement number CN216407070U), which discloses a circulating water pump for bleaching powder production, relating to the field of circulating water pump technology. This utility model includes a base, with a support plate fixedly connected to the upper surface of the base. By adjusting the height of the circulating water pump body, this utility model facilitates the alignment of the connecting pipe with bleaching powder production machines at different water outlet heights and allows for connection to the machines for subsequent water circulation. The adjustable height of the circulating water pump body also facilitates installation, effectively improving installation efficiency. While the pump meets basic usage requirements, its weak backflow prevention effect causes liquid backflow, impacting the impeller and subjecting it to reverse impact forces. Over time, this can lead to cracks, deformation, or even breakage of the impeller blades, and also accelerates wear at the connection between the impeller and the shaft, resulting in loosening of the connection. Utility Model Content

[0004] The purpose of this invention is to provide a circulating water pump for bleaching powder production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circulating water pump for bleaching powder production, comprising a fixed base for support, a U-shaped support plate for fixing the circulating water pump installed on the side of the fixed base, a protective cover for preventing the overflow of circulating water for bleaching powder production fixedly installed on the top of the U-shaped support plate, a connecting pipe connected to the outer periphery of the protective cover, a check pipe connected to the end of the connecting pipe away from the protective cover, and a circulating water outlet pipe for the inlet of circulating water for bleaching powder production connected to the side of the check pipe;

[0006] The side of the check valve is connected to a guide groove for sliding. A spring is connected inside the guide groove. One end of the spring is connected to a movable plate. A movable frame is connected to the side of the movable plate.

[0007] Preferably, the movable frame is equipped with a limiting plate for limiting position, and the surface of the limiting plate is provided with two guide grooves, and the end of the movable frame is slidably disposed inside the grooves.

[0008] Preferably, the surface of the movable frame is provided with a water outlet groove for increasing water flow, and a connecting column is connected to the side of the movable frame. A conical block is installed at the end of the connecting column away from the movable frame to prevent backflow of circulating water for bleaching powder production.

[0009] Preferably, the inner wall of the movable frame is fitted with a tapered plate for use with the tapered block, and a crossbar is welded to the inner wall of the movable frame.

[0010] Preferably, the crossbar is rotatably connected to a rotating column, and the end of the rotating column is equipped with a turbulence-inducing blade for contacting the circulating water used in the bleaching powder production.

[0011] Preferably, a motor is mounted on the top of the fixed base, and an eccentric wheel is mounted on the output shaft of the motor via a coupling. Multiple blades for promoting the circulation of water used in bleaching powder production are mounted on the outer periphery of the eccentric wheel.

[0012] Preferably, a filter plate for filtration is installed inside the protective cover, and a circulating water inlet pipe is connected to the outer periphery of the protective cover.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This circulating water pump for bleaching powder production utilizes a conical block and conical plate structure. When circulating water enters the check pipe, it pushes the conical block, causing it to separate from the conical plate, thus achieving water circulation. When the circulating water stops flowing, to prevent backflow, a spring pulls the moving plate, moving frame, and conical block closer to the conical plate, ultimately resulting in tight contact between the conical block and the conical plate, achieving a backflow prevention effect. Compared to traditional circulating water pumps used in bleaching powder production, which have a weak backflow prevention effect, this structure enhances the backflow prevention capability, prevents impeller blades from cracking, deforming, or even breaking, reduces wear at the connection between the impeller and the shaft, and makes the connection more stable.

[0015] This circulating water pump used in bleaching powder production benefits from the structure of the turbulence-disrupting blades. When the circulating water comes into contact with the turbulence-disrupting blades, the blades begin to rotate, achieving the effect of disturbing the circulating water. When rotating, the turbulence-disrupting blades can break the laminar flow state of the liquid, allowing different substances to come into full contact, making the reaction more uniform and efficient, and improving the quality and yield of bleaching powder.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5The circulating water pump for bleaching powder production shown includes a fixed base 1 for support, a U-shaped support plate 101 for fixing the circulating water pump is installed on the side of the fixed base 1, a protective cover 105 for preventing the overflow of circulating water for bleaching powder production is fixedly installed on the top of the U-shaped support plate 101, a connecting pipe 201 is connected to the outer periphery of the protective cover 105, a check pipe 2 is connected to the end of the connecting pipe 201 away from the protective cover 105, and a circulating water outlet pipe 202 for the inlet of circulating water for bleaching powder production is connected to the side of the check pipe 2.

[0027] The side of the check valve 2 is connected to a guide groove 203 for sliding. A spring 204 is connected inside the guide groove 203. A spring is provided between the spring 204 and the guide groove 203. One end of the spring 204 is connected to a moving plate 205. A moving frame 3 is connected to the side of the moving plate 205. A limiting plate 206 for limiting is installed inside the moving frame 3. Two guide grooves 207 are provided on the surface of the limiting plate 206. The end of the moving frame 3 is slidably disposed inside the grooves 207. A water outlet groove 302 for increasing water flow is provided on the surface of the moving frame 3. A connecting column 301 is connected to the side of the movable frame 3. A conical block 303 is installed at the end of the connecting column 301 away from the movable frame 3 to prevent the backflow of circulating water used in bleaching powder production. When the circulating water enters the check pipe 2, the circulating water pushes the conical block 303, and the conical block 303 separates from the conical plate 304 to achieve the purpose of water circulation. When the circulating water stops flowing, to prevent the circulating water from flowing back, the spring 204 pulls the movable plate 205, the movable frame 3 and the conical block 303 closer to the conical plate 304. Finally, the conical block 303 and the conical plate 304 make close contact to achieve the backflow prevention effect.

[0028] The inner wall of the movable frame 3 is equipped with a conical plate 304 for use with the conical block 303. A crossbar 4 is welded to the inner wall of the movable frame 3. A rotating column 401 is rotatably connected inside the crossbar 4. A turbulence-inducing blade 402 is installed at the end of the rotating column 401 for contact with the circulating water used in the production of bleaching powder. When the circulating water comes into contact with the turbulence-inducing blade 402, the turbulence-inducing blade 402 starts to rotate, thereby turbulenting the circulating water. When rotating, the turbulence-inducing blade 402 can break the laminar flow state of the liquid, allowing different substances to come into full contact, making the reaction more uniform and efficient, and improving the quality and yield of bleaching powder.

[0029] A motor 102 is mounted on the top of the fixed base 1, which provides power for the operation of the water pump. A motor 102 with a high protection rating is typically selected to withstand the corrosive gases and humid environment that may exist in the bleaching powder production workshop. An eccentric wheel 103 is mounted on the output shaft of the motor 102 via a coupling. Multiple blades 104 are mounted on the outer circumference of the eccentric wheel 103 to promote the circulation of water used in bleaching powder production. The blades 104 are the core working components of the water pump, performing work on the liquid through high-speed rotation, thus giving the liquid energy. The blades 104 are typically made of corrosion-resistant, high-strength materials such as stainless steel (316L, etc.), ceramics, or fluoroplastics. The shape and number of blades of the impeller 104 affect the performance of the water pump. Common blades are backward-curved blades, which can improve the efficiency of the water pump. The inside of the protective cover 105 is equipped with a filter plate 106 for filtration. The filter plate 106 filters the circulating water. The outer periphery of the protective cover 105 is connected to the circulating water inlet pipe 107. The inlet pipe 202 and the outlet pipe 107 are connected to the bleaching powder production circulation system. When the motor 102 is turned on, the motor 102 drives the eccentric wheel 103 to rotate. The eccentric wheel 103 drives the impeller 104 to rotate. The impeller 104 circulates the water used for bleaching powder production. The circulating water enters the protective cover 105 from the outlet pipe 107 and the filter plate 106, enters the check pipe 2 through the connecting pipe 201, and enters the bleaching powder production circulation system through the inlet pipe 202, thus completing the circulation of the water used for bleaching powder production.

[0030] Working principle

[0031] This circulating water pump is used in bleaching powder production. In operation, the inlet pipe 202 and outlet pipe 107 are first connected to the bleaching powder production circulation system. The motor 102 is then turned on, driving the eccentric wheel 103 to rotate. The eccentric wheel 103 drives the impeller 104 to rotate, circulating the water used in bleaching powder production. The circulating water enters the protective cover 105 through the outlet pipe 107 and filter plate 106, then flows through the connecting pipe 201 into the check pipe 2, and finally through the inlet pipe 202 into the bleaching powder production circulation system, completing the bleaching powder production water circulation. The filter plate 106 filters the circulating water. When the circulating water enters the check pipe 2, it pushes the conical block 303, which separates from the conical plate 304, thus achieving water circulation. When the circulating water stops flowing, to prevent backflow, the spring 204 pulls the moving plate 205, the moving frame 3, and the conical block 303 toward the conical plate 304. Finally, the conical block 303 and the conical plate 304 come into close contact, achieving a backflow prevention effect. When the circulating water comes into contact with the turbulence blade 402, the turbulence blade 402 begins to rotate, thus agitating the circulating water.
