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

[0005] The purpose of the present invention is to provide a self-circulating cooling chemical pump to solve the problem raised in the above background technology that when the chemical pump encounters a surge in material delivery volume, a sudden change in medium viscosity, etc., the motor load increases instantaneously and the heat generation rate increases exponentially.

[0010] Further, a positioning column is fixedly installed at the outer edge of one side of the disc away from the rotating column. A rectangular frame is penetrated and slidably snap-fitted to the outside of the positioning column. A moving rod is fixedly installed at the middle position of the bottom end of the rectangular frame.

[0011] Furthermore, a fixed seat is fixedly installed on the outside of one side of the motor close to the moving rod, one end of the moving rod is slidably installed on the outside of the bottom side of the fixed seat, a suction cylinder is longitudinally fixedly installed on the outside of the bottom side of the fixed seat, a piston block is fixedly installed on the bottom end of the moving rod, and the piston block is slidingly sealed and installed inside one side of the suction cylinder.

[0014] Furthermore, a sprocket 1 is fixedly installed at one end of the reciprocating screw, a sprocket 2 is fixedly installed through the outside of the side of the disc close to the rotating column, and a chain is provided between the sprocket 1 and the sprocket 2 for transmission connection.

[0015] Furthermore, an arc block is provided on the outside of one side of the reciprocating screw and the limit rod, the arc block and the reciprocating screw are connected by a through thread, and the arc block and the limit rod are sliding through, the top of the wiping cotton is fixedly mounted on the bottom wall of the arc block, the bottom end of the wiping cotton is fitted with the outer surface of the motor, and an extrusion block is fixedly provided on the side of the mounting ring close to the bottom end of the wiping cotton, and the top side profile of the extrusion block is arc-shaped.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By placing a surrounding cooling pipe inside the limiting cavity, the cooling pipe can be closer to the heat source of the motor, shortening the heat conduction path, enabling the heat generated during the operation of the motor to be conducted to the surface of the cooling pipe more quickly and efficiently, and improving the heat exchange efficiency. When the chemical pump encounters situations such as a sudden increase in the material transportation volume or a sudden change in the medium viscosity, the motor load increases instantaneously, and the heat generation rate rises exponentially. At this time, the self-triggering drive component is triggered to operate, so that one side of the spray component can operate synchronously with the motor drive, thereby enabling some external water flow to be suctioned and extruded orderly, and then sprayed out 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, using the principle of latent heat of phase change, it quickly evaporates and absorbs a large amount of heat to cool down, enabling this chemical pump to utilize the dual mechanisms of basic heat dissipation and emergency spray heat dissipation to operate synergistically, ensuring efficient heat dissipation under normal working conditions, and being able to intervene in a timely manner 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 a complex environment.

[0017] 2. When the spray component is operating, it can synchronously drive the wiping component to operate. Thus, while the water mist is sprayed onto the surface of the motor housing, the wiping component operates synchronously. By means of physical contact, the attached water film is quickly thinned 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 also be generated, further promoting the diffusion of the water vapor and accelerating the water evaporation efficiency, strengthening the immediate effect of spray heat dissipation to a certain extent, and being able to remove the excessive water vapor accumulated between the external heat dissipation fins of the motor housing in real time, avoiding the risk of water penetration caused by an overly thick local water film.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0021] Embodiment 1: Please refer to Figure 1 - Figure 8, a self-circulating cooling chemical pump, including a pump base 1, a pump body 2 fixed on 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 on one side of the top of the pump base 1. A number of heat dissipation fins 8 are fixedly arranged around the outside of the motor 3 at equal intervals. A liquid inlet 4 and a liquid outlet 5 are opened on the pump body 2. A limiting cavity 6 is arranged around the inside of the motor 3 housing. A cooling pipe 7 is arranged around the inside of the limiting cavity 6. The output end and the input end of the cooling pipe 7 both penetrate and are fixed inside one side of the pump body 2. One end of the central shaft of the motor 3 away from the pump body 2 is fixed with a coaxial reducer 9. The coaxial reducer 9 is fixed on the outside of one side of the motor 3. The output end of the coaxial reducer 9 is provided with a self-triggering drive assembly and a spraying assembly.

[0022] The spraying assembly includes a rotating column 20, a disc 22 and a number of spraying pipes 32. The rotating column 20 is rotationally clamped and installed on the outside of one side of the output end of the coaxial reducer 9 through a bracket. The disc 22 is fixedly installed on the outside of one end of the rotating column 20 away from the coaxial reducer 9. One ends of the number of spraying pipes 32 are fixedly installed around the outside of the motor 3 in sequence.

[0023] The self-triggering drive assembly includes a limiting ring 13, a number of limiting columns one 19 and a number of limiting columns two 21. The limiting ring 13 penetrates and is horizontally slidably clamped and installed on the outside of the output end of the coaxial reducer 9. The number of limiting columns one 19 are fixedly installed around the outside of one side of the limiting ring 13 close to the rotating column 20 at equal angles. The number of limiting columns two 21 are fixedly installed around the outside of one side of the rotating column 20 close to the limiting ring 13 at equal angles.

[0024] A strong magnetic ring 14 is rotationally clamped and installed through the outside of the limiting ring 13. 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 housing of the coaxial reducer 9. A strong electromagnetic ring 16 is fixedly installed on the outside of one side of the housing 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 to the same pole.

[0025] Specifically, through the setting of the existing coaxial reducer 9, the rotation speed of the output shaft at the rear end of the motor 3 is slowed down to avoid other problems caused by too high rotation speed.

[0026] A heat conduction pipe 10 penetrates and is arranged inside one side of the motor 3 close to the coaxial reducer 9. A piston rod 11 is slidably installed through the inside of one side of the heat conduction pipe 10. A conduction block 12 is fixedly installed at the penetrating end of the piston rod 11 close to the coaxial reducer 9. A thermally expandable and contractible liquid is filled inside one side of the heat conduction pipe 10 close to the piston end of the piston rod 11. A conduction seat one 17 and a conduction seat two 18 are fixedly installed on the outside of the housing of the coaxial reducer 9 close to both sides of the conduction block 12. A wire is connected between the conduction seat one 17 and the strong electromagnetic ring 16.

[0027] A positioning post 23 is fixedly installed at the outer edge of the side of the disc 22 away from the rotating column 20. A rectangular frame 24 is slidably engaged and installed through the outside of the positioning post 23. A moving rod 25 is fixedly installed at the middle position of the bottom end of the rectangular frame 24.

[0028] A fixed seat 26 is fixedly installed on the outside of the side of the motor 3 close to the moving rod 25. One end of the moving rod 25 is slidably installed through the outside of the bottom end of one side of the fixed seat 26. A suction cylinder 27 is longitudinally fixedly installed on the outside of the bottom end of one side of the fixed seat 26. A piston block 28 is fixedly installed at the bottom end of the moving rod 25. The piston block 28 is slidably and sealingly installed inside one side of the suction cylinder 27.

[0029] A one-way liquid inlet valve pipe 29 is fixedly installed through the bottom end of one side of the suction cylinder 27. A one-way liquid discharge valve pipe 30 is fixedly installed through the bottom end of the other side of the suction cylinder 27. A conduction box 31 is arranged through between one ends of the spray pipes 32 close to the disc 22. The output end of the one-way liquid discharge valve pipe 30 is fixedly installed through the inside of one side of the conduction box 31.

[0030] In this embodiment, when the self-circulating cooling chemical pump is in use, first, the conduction seat one 17 is connected to an external power supply through a wire to ensure subsequent power supply. Then, the motor 3 is started. Through the rotation of the output shaft of the motor 3, the blades inside the pump body 2 are driven to rotate. With the conduction of the liquid inlet 4 and the liquid outlet 5, liquid pumping is carried out. 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 perform self-circulating cooling and heat dissipation on the motor 3. At the same time, through the opening of the limiting cavity 6 and the surrounding arrangement 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, enabling the heat generated by the operation of the motor 3 to be conducted to the surface of the cooling pipe 7 more quickly and efficiently, and improving the heat exchange efficiency.

[0031] 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.

[0032] 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.

[0033] 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 .

[0034] 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.

[0035] 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.

[0036] An arc-shaped block 39 is penetrated and arranged on the outer sides of the reciprocating lead screw 34 and the limiting rod 38. The arc-shaped block 39 is connected to the reciprocating lead screw 34 by a penetrating thread, and the arc-shaped block 39 is in penetrating sliding connection with the limiting rod 38. The top end of the wiping cotton 40 is fixedly installed on the bottom wall of the arc-shaped block 39, and the bottom end of the wiping cotton 40 is attached to the outer surface of the motor 3. A pressing block 41 is fixedly arranged on one side of the mounting ring 33 close to the bottom end of the wiping cotton 40, and the top side profile of the pressing block 41 is arc-shaped.

[0037] In this embodiment, when the disc 22 rotates, it will drive the sprocket two 36 on one side to rotate synchronously. Through the transmission connection of the chain 37, the rotation of the sprocket two 36 drives the sprocket one 35 to rotate synchronously. Through the rotation of the sprocket one 35, the reciprocating lead screw 34 is driven to rotate synchronously. Through the rotation of the reciprocating lead screw 34 and the limitation of the limiting rod 38, the arc-shaped block 39 can drive the wiping cotton 40 at the bottom to perform a reciprocating wiping movement on the outer 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 thinned 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 also be generated, further promoting the diffusion of the water vapor and accelerating the water evaporation efficiency, to a certain extent strengthening the immediate effect of spray cooling. At the same time, due to the moisture absorption characteristics of the wiping cotton 40, when the arc-shaped block 39 drives the wiping cotton 40 to reciprocate on the outer surface of the motor 3 housing, it can also timely remove the excessive water vapor accumulated between the heat dissipation fins 8 at the top of the motor 3 housing, avoiding the risk of water penetration caused by an overly thick local water film, and the overall use effect is better. When the arc-shaped block 39 drives the wiping cotton 40 to move to one side of the mounting ring 33, at this time the wiping cotton 40 will contact the arc-shaped pressing block 41. As the arc-shaped slope at the top of the pressing block 41 changes, the space of the wiping cotton 40 can be restricted, thereby squeezing the wiping cotton 40 to squeeze out the water inside the wiping cotton 40, ensuring the repeated use effect of the wiping cotton 40.
