Description

Technical Field

[0001] The invention relates to the technical field of chemical pumps, in particular to a self-circulating cooling chemical pump. Background Art

[0002] Chemical pumps come in a variety of types, including stainless steel, plastic, fluoroplastic, electric, and pneumatic. They are widely used in industrial and urban water supply and drainage, as well as in farmland and orchard irrigation and drainage. They primarily transport clean water or other liquids with similar physical and chemical properties. Chemical pumps are typically driven by electric motors, whose efficiency is affected by changes in their own temperature.

[0003] A self-circulating cooling chemical pump announced by Chinese patent CN118188591B is provided with a cooling component, a first guide pipe and a second guide pipe. The liquid enters the first guide pipe from the pump body at a relatively fast speed, and under the subsequent push of the liquid, the liquid enters the cooling component along the first guide pipe, and then flows from the cooling component into the second guide pipe and flows back into the pump body. The liquid flows along the cooling component so that the liquid forms a wrap around the main motor on the outside of the main motor. Due to the fast flow rate of the liquid, the liquid around the main motor can be kept at a low temperature, thereby improving the heat dissipation speed of the main motor, maintaining the main motor working at the optimal temperature, and then reducing the energy consumption of the main motor, providing a chemical pump with energy-saving effect.

[0004] In the above solution, the heat emitted around the motor is cooled by using the self-circulating flow of the fluid. Under normal working conditions, the system can still maintain the basic heat dissipation requirements of the motor. However, when the chemical pump encounters a surge in material delivery volume or a sudden change in medium viscosity, the motor load increases instantly and the heat generation rate increases exponentially. At this time, the fixed flow coolant circulation system cannot quickly improve the cooling efficiency, resulting in a large amount of heat accumulation inside the motor, especially the temperature of the flow pipe and the heat dissipation outer shell area continues to rise, which seriously threatens the safe and stable operation of the motor and may damage the motor parts. The overall circulation cooling effect needs to be improved. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By placing a surrounding cooling pipe inside the limit cavity, the cooling pipe can be closer to the heat source of the motor, shortening the heat conduction path, so that the heat generated by the motor operation can be more quickly and efficiently transferred to the surface of the cooling pipe, improving the heat exchange efficiency. When the chemical pump encounters a surge in material conveying volume or a sudden change in medium viscosity, the motor load increases instantly and the heat generation rate increases exponentially. At this time, the self-triggering drive component is triggered to operate, so that the spray component on one side can operate synchronously with the motor drive, thereby being able to orderly suck and squeeze part of the external water flow, and then spray it from several spray pipes, so that the sprayed water mist evenly covers the surface of the motor housing in the form of a fan-shaped mist curtain. When the water mist contacts the high-temperature components, it uses the principle of phase change latent heat to quickly evaporate and absorb a large amount of heat, thereby cooling the temperature. This allows the chemical pump to use the dual mechanisms of basic heat dissipation and emergency spray heat dissipation to work together to ensure efficient heat dissipation under normal working conditions, and can intervene in time when the motor is overloaded, significantly improving the overall heat dissipation efficiency, enhancing the load bearing capacity of the device under extreme working conditions, and ensuring the stable and reliable operation of the chemical pump in complex environments.

[0018] 2. When the spray component is running, it can drive the wiping component to run synchronously, so that when the water mist is sprayed onto the surface of the motor housing, the wiping component runs synchronously, and the attached water film is quickly diluted and dispersed by physical contact, thereby increasing the surface area of ​​the water vapor. At the same time, during the reciprocating wiping operation, a certain airflow disturbance will be generated, which further promotes the diffusion of water vapor and accelerates the evaporation efficiency of water, enhancing the immediate effect of spray heat dissipation to a certain extent. At the same time, it can also clear the excess water vapor accumulated between the heat dissipation fins outside the motor housing in real time, avoiding the risk of water penetration caused by excessive thickness of the local water film.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1 - Figure 8A self-circulating cooling chemical pump comprises a pump base 1, a pump body 2 fixed to one side of the top of the pump base 1, and a motor 3 arranged on one side of the pump body 2. The motor 3 is fixed to one side of the top of the pump base 1, and a number of heat dissipation fins 8 are fixed around the outside of the motor 3 at equal intervals. A liquid inlet 4 and a liquid discharge port 5 are provided on the pump body 2. A limiting cavity 6 is provided around the inside of the motor 3 shell, and a cooling pipe 7 is provided around the inside of the limiting cavity 6. The output and input ends of the cooling pipe 7 are both passed through and fixed inside one side of the pump body 2. A coaxial reducer 9 is fixed on the end of the central axis of the motor 3 away from the pump body 2. The coaxial reducer 9 is fixed to the outside of one side of the motor 3, and the output end of the coaxial reducer 9 is provided with a self-triggering drive assembly and a spray assembly.

[0034] The spray assembly includes a rotating column 20, a disc 22 and a plurality of spray tubes 32. The rotating column 20 is mounted on the outside of the output end of the coaxial reducer 9 through a bracket. The disc 22 is fixedly mounted on the outside of the end of the rotating column 20 away from the coaxial reducer 9. One end of the plurality of spray tubes 32 is fixedly mounted on the outside of the motor 3 in sequence.

[0035] The self-triggering drive assembly includes a limit ring 13, several limit columns 19 and several limit columns 21. The limit ring 13 is installed on the outside of the output end of the coaxial reducer 9 by sliding horizontally. Several limit columns 19 are fixedly installed at equal angles around the outside of the limit ring 13 on one side close to the rotating column 20. Several limit columns 21 are fixedly installed at equal angles around the outside of the rotating column 20 on one side close to the limit ring 13.

[0036] A strong magnetic ring 14 is installed on the outside of the limit ring 13 for rotation and engagement. Spring compression rods 15 are fixedly installed on both sides of the strong magnetic ring 14. One end of the spring compression rod 15 is fixedly installed on the outside of one side of the outer shell of the coaxial reducer 9. A strong electromagnetic ring 16 is fixedly installed on the outside of the outer shell side of the coaxial reducer 9 close to the strong magnetic ring 14. The adjacent surfaces of the strong magnetic ring 14 and the strong electromagnetic ring 16 are set with the same poles.

[0037] Specifically, by setting up the existing coaxial reducer 9, the rotation speed of the output shaft at the rear end of the motor 3 is slowed down, thereby avoiding other problems caused by excessively high rotation speed.

[0038] A heat conducting pipe 10 is provided inside the side of the motor 3 close to the coaxial reducer 9, a piston rod 11 is slidably installed inside the side of the heat conducting pipe 10, a conducting block 12 is fixedly installed on the end of the piston rod 11 close to the coaxial reducer 9, and the inside of the side of the heat conducting pipe 10 close to the piston end of the piston rod 11 is filled with a liquid that expands with heat and contracts with cold, a conducting seat 17 and a conducting seat 2 18 are fixedly installed on the outside of the shell of the coaxial reducer 9 close to both sides of the conducting block 12, and the conducting seat 17 and the powerful electromagnetic ring 16 are connected by a wire.

[0039] A positioning column 23 is fixedly mounted on the outer edge of the disc 22 away from the rotating column 20 . A rectangular frame 24 is slidably mounted on the outside of the positioning column 23 . A moving rod 25 is fixedly mounted at the middle position of the bottom end of the rectangular frame 24 .

[0040] A fixed seat 26 is fixedly installed on the outside of one side of the motor 3 close to the moving rod 25, one end of the moving rod 25 is slidably installed on the outside of the bottom end of the fixed seat 26, a suction cylinder 27 is longitudinally fixedly installed on the outside of the bottom end of the fixed seat 26, and a piston block 28 is fixedly installed on the bottom end of the moving rod 25, and the piston block 28 is slidably and sealedly installed on the inside of one side of the suction cylinder 27.

[0041] A one-way liquid inlet valve tube 29 is fixedly installed through one side of the bottom end of the suction cylinder 27, and a one-way liquid discharge valve tube 30 is fixed through the other side of the bottom end of the suction cylinder 27. A conduction box 31 is provided between the ends of the spray tube 32 close to the disc 22, and the output end of the one-way liquid discharge valve tube 30 is fixedly installed inside one side of the conduction box 31.

[0042] In this embodiment, when the self-circulating cooling chemical pump is in use, the conductive seat 17 is first connected to the external power supply through a wire to ensure subsequent power supply, and then the motor 3 is started, and the rotation of the output shaft of the motor 3 drives the blades inside the pump body 2 to rotate, and the liquid inlet 4 and the liquid discharge port 5 are connected to each other, so as to pump the liquid. When the liquid is pumped, a part of it will enter through the input end of the cooling pipe 7, and then return from the output end of the cooling pipe 7, so as to self-circulate and cool the motor 3. At the same time, through the opening of the limit cavity 6 and the surrounding setting of the internal cooling pipe 7, the cooling pipe 7 can be closer to the heat source of the motor 3, shortening the heat conduction path, so that the heat generated by the operation of the motor 3 can be more quickly and efficiently conducted to the surface of the cooling pipe 7, thereby improving the heat exchange efficiency.

[0043] It should also be noted that when the chemical pump encounters a surge in material delivery volume, a sudden change in medium viscosity, etc., the load on the motor 3 increases instantaneously, and the heat generation rate increases exponentially. At this time, the existing thermal expansion and contraction liquid inside the heat pipe 10 will expand due to the heat, thereby pushing the piston rod 11 on one side to move outward. When the piston rod 11 moves, it will drive the conductive block 12 on one side to move synchronously. When the conductive block 12 moves between the conductive seat 17 and the conductive seat 2 18, the strong electromagnetic ring 16 is connected to the external power supply to generate magnetic force. Combined with the same pole setting of the adjacent surfaces of the strong electromagnetic ring 16 and the strong magnetic ring 14, the strong electromagnetic ring 16 will generate a repulsive force on the strong magnetic ring 14 on one side after being energized, so that the strong magnetic ring 14 drives several limit posts 19 on one side of the limit ring 13 to move synchronously, thereby Several limit posts 19 are inserted between several limit posts 21 on one side, so that the positioning post 23 will slowly rotate with the rotation of the output shaft of the motor 3, thereby triggering the operation of the spray assembly and the wiping assembly on one side. When the temperature of the motor 3 drops, the existing thermal expansion and contraction liquid inside the heat pipe 10 will shrink, so that the piston rod 11 drives the conductive block 12 to move back and away from between the conductive seat 1 17 and the conductive seat 2 18, so that the strong electromagnetic ring 16 is powered off and loses its repulsive force. At this time, the rebound of the compression spring inside the spring compression rod 15 pulls the limit ring 13 and the strong magnetic ring 14 back and resets, so that the limit post 19 and the limit post 2 21 lose contact, and the spray assembly and the wiping assembly stop running, avoiding ineffective energy consumption, and the overall use effect is good.

[0044] It should also be noted that when the rotating column 20 rotates, it will drive the disc 22 on one side to rotate, and through the rotation of the disc 22, the external positioning column 23 will be driven to rotate synchronously. At the same time, the rectangular frame 24 is connected to the positioning column 23 by sliding, and the moving rod 25 is installed longitudinally with the fixing seat 26 by sliding. As a result, the positioning column 23 will drive the moving rod 25 to perform longitudinal reciprocating motion when it rotates. Through the longitudinal reciprocating motion of the moving rod 25, the piston block 28 at the bottom is driven to perform synchronous longitudinal reciprocating motion inside the suction cylinder 27. At this time, the input end of the existing one-way liquid inlet valve pipe 29 is connected to the external water tank, so that the piston block 28 can draw in water from the outside when it moves up to suck, and then the piston block 28 can squeeze when it moves down. , it can squeeze the drawn water into the interior of the existing one-way discharge valve pipe 30, and then evenly guide the squeezed water into the interior of several spray pipes 32 through the conduction box 31, and then spray it out from the nozzle outside the spray pipe 32, so that the sprayed water mist evenly covers the surface of the motor 3 shell in the form of a fan-shaped mist curtain. When the water mist contacts the high-temperature components, it uses the principle of phase change latent heat to quickly evaporate and absorb a large amount of heat, thereby cooling down. This allows the chemical pump to use the dual mechanisms of basic heat dissipation and emergency spray heat dissipation to work together, ensuring efficient heat dissipation under normal working conditions, and can intervene in time when the motor 3 is overloaded, significantly improving the overall heat dissipation efficiency, enhancing the load bearing capacity of the device under extreme working conditions, and ensuring the stable and reliable operation of the chemical pump in complex environments.

[0045] Example 2: Please refer to Figure 9 - Figure 12 This embodiment further illustrates the first embodiment, in which a wiping component is provided on the outside of the top end of the motor 3 .

[0046] The wiping assembly includes a mounting ring 33, a reciprocating screw rod 34 and a wiping cotton 40. The mounting ring 33 is fixedly installed at the top outer edge of the side of the motor 3 away from the coaxial reducer 9. The reciprocating screw rod 34 is rotatably installed at the bottom side edge of the mounting ring 33. The wiping cotton 40 is arranged on the outside of one side of the mounting ring 33. A limiting rod 38 is fixedly installed on the top side of the mounting ring 33.

[0047] A sprocket 1 35 is fixedly installed at one end of the reciprocating screw rod 34 , a sprocket 2 36 is fixedly installed through the outer portion of the disc 22 close to the rotating column 20 , and a chain 37 is provided between the sprocket 1 35 and the sprocket 2 36 for transmission connection.

[0048] An arc block 39 is provided on the outside of one side of the reciprocating screw 34 and the limit rod 38. The arc block 39 and the reciprocating screw 34 are connected by a through thread, and the arc block 39 and the limit rod 38 are connected by a through sliding. The top of the wiping cotton 40 is fixedly mounted on the bottom wall of the arc block 39, and the bottom end of the wiping cotton 40 is in contact with the outer surface of the motor 3. An extrusion block 41 is fixedly provided on the side of the mounting ring 33 near the bottom end of the wiping cotton 40, and the top side profile of the extrusion block 41 is arc-shaped.

[0049] In this embodiment, when the disc 22 rotates, it will drive the sprocket 2 36 on one side to rotate synchronously. Through the transmission connection of the chain 37, the rotation of the sprocket 2 36 drives the sprocket 1 35 to rotate synchronously. The rotation of the sprocket 1 35 drives the reciprocating screw 34 to rotate synchronously. Through the rotation of the reciprocating screw 34 and the limiting of the limit rod 38, the arc block 39 can drive the bottom wiping cotton 40 to perform a reciprocating wiping motion on the outside of the top of the motor 3. Through this physical wiping contact method, the water film attached to the surface of the motor 3 can be quickly diluted and dispersed, thereby increasing the surface area of ​​the water vapor. At the same time, during the reciprocating wiping operation, a certain airflow disturbance will be generated, which further promotes the diffusion of water vapor and accelerates the evaporation efficiency of water. , which to a certain extent enhances the immediate effect of spray heat dissipation. At the same time, due to the hygroscopic characteristics of the wiping cotton 40, the arc block 39 drives the wiping cotton 40 to move back and forth on the surface of the motor 3 casing. It can also clear the excess water vapor accumulated between the external heat dissipation fins 8 at the top of the motor 3 casing in real time, avoiding the risk of moisture penetration due to excessive thickness of the local water film, and the overall use effect is better. When the arc block 39 drives the wiping cotton 40 to move to one side of the mounting ring 33, the wiping cotton 40 will contact the arc-shaped extrusion block 41. As the arc slope of the top of the extrusion block 41 changes, the space of the wiping cotton 40 can be limited, thereby squeezing the wiping cotton 40, thereby squeezing out the moisture inside the wiping cotton 40, and ensuring the reuse effect of the wiping cotton 40.
