Technical Field

[0001] This utility model relates to the field of diaphragm pumps, and more particularly to a diaphragm pump with heat dissipation effect. Background Technology

[0002] Diaphragm pumps are characterized by their simple structure and ease of use, and can meet the special requirements of different industries. They are now widely used in many industries such as chemical, pharmaceutical, water treatment, and food, and are suitable for conveying various chemical media, corrosive liquids, high-viscosity liquids, and suspensions.

[0003] Existing diaphragm pumps operate with the eccentric wheel and rotating frame rotating at high speed relative to each other, which easily leads to heat accumulation and high temperatures near the eccentric wheel and rotating frame, potentially damaging them. To address this issue, a diaphragm pump with heat dissipation capabilities is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a diaphragm pump with heat dissipation capabilities.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a diaphragm pump with heat dissipation effect, comprising a pump body, a sealing seat fixedly connected to the top of the pump body, a diaphragm fixedly connected to the bottom of the sealing seat, a connecting seat fixedly connected to the middle of the diaphragm, a rubber pad fixedly connected to the bottom of the pump body, a drive assembly disposed on the top of the rubber pad, the top of the drive assembly connected to the connecting seat, two channels penetrating and formed on both sides of the sealing seat, an installation groove penetrating and formed between the two channels, a sealing plate disposed in the installation groove, a water outlet pipe disposed on the top of the two channels on the right, a water inlet pipe disposed on the top of the two channels on the left, polyurethane foam fixedly connected to the inner wall of the pump body, a cooling pipe fixedly connected to the inner wall of the pump body, a water tank disposed at the front end of the pump body, a water pump fixedly connected to the top of the water tank, and a pumping pipe fixedly connected to both the front and rear ends of the water pump.

[0006] As a further description of the above technical solution: The drive assembly includes a motor, the bottom of which is fixedly connected to a rubber pad, and an eccentric disk is fixedly connected to the output end of the motor. A connecting rod is rotatably connected to the outside of the eccentric disk, and the top of the connecting rod is connected to the bottom of the connecting seat.

[0007] As a further description of the above technical solution: The bottom of both the inlet and outlet pipes are fixedly connected to the top of the sealing seat.

[0008] As a further description of the above technical solution: The polyurethane foam is disposed on the outside of the drive assembly.

[0009] As a further description of the above technical solution: The end of the front-end water pumping pipe passes through and is fixedly connected to the water tank, while the end of the rear-end water pumping pipe passes through the pump body and is fixedly connected to the cooling pipe.

[0010] As a further description of the above technical solution: A return pipe is fixedly connected to the lower end of the cooling pipe, and the return pipe passes through the pump body and is fixedly connected to the water tank.

[0011] As a further description of the above technical solution: A semiconductor cooling chip is fixedly connected to the outside of the water tank.

[0012] This utility model has the following beneficial effects: In this invention, when the mechanical friction of the drive components generates heat, the water pump draws low-temperature coolant from the water tank through the pumping pipe and delivers the coolant to a cooling pipe with a fixed wall thickness in the pump body. The cooling pipe is spirally distributed along the inner wall of the pump body, which can evenly absorb the heat generated inside the pump body. Furthermore, when the semiconductor cooling chip on the outside of the water tank is energized, it quickly cools the coolant after it flows back, preventing the internal temperature of the pump body from becoming too high during operation, extending the service life of vulnerable parts, ensuring long-term stable operation of the equipment, and the porous polyurethane foam can effectively absorb the mechanical noise generated by the drive components during operation. Combined with the rubber pad to absorb the vibration energy of the motor during operation, it reduces the noise during the operation of the pump body. Attached Figure Description

[0017] Reference Figure 1-4This utility model provides an embodiment of a diaphragm pump with heat dissipation effect, including a pump body 1. A sealing seat 2 is fixedly connected to the top of the pump body 1, and a diaphragm 3 is fixedly connected to the bottom of the sealing seat 2. Liquid can enter and exit through the reciprocating motion of the diaphragm 3. A connecting seat 4 is fixedly connected to the middle of the diaphragm 3. A rubber pad 5 is fixedly connected to the bottom of the pump body 1. The rubber pad 5 is made of medium-hardness nitrile rubber or EPDM rubber, and its elastic coefficient has been precisely calculated. It can absorb vibration through elastic deformation without causing displacement deviation in the transmission link between the output shaft of the motor 6 and the eccentric disk 7 and the connecting rod 8 due to excessive deformation. A drive assembly is provided on the top of the rubber pad 5. The top of the drive assembly is connected to the connecting seat 4. Two channels 9 are opened through both sides of the sealing seat 2. An installation groove 10 is opened through the two channels 9. The bottom of the left installation groove 10 is arc-shaped, and the top of the right installation groove 10 is arc-shaped. The grooves on both sides of the channel 9 can facilitate the limiting of the sealing plate 11. A sealing plate 11 is installed inside the mounting slot 10 to intercept the flow. Water outlet pipes 12 are installed at the top of the two right-side channels 9, and water inlet pipes 13 are installed at the top of the two left-side channels 9 for easy water intake and exhaust. Polyurethane foam 14 is fixedly connected to the inner wall of the pump body 1 for noise reduction. A spiral-shaped cooling pipe 15 is fixedly connected to the inner wall of the pump body 1. A water tank 16 is installed at the front end of the pump body 1, and a water injection pipe (not shown in the figure) is installed on the outside of the water tank 16. A water pump 17 is fixedly connected to the top of the water tank 16, and water pump 17 has suction pipes 18 fixedly connected to both its front and rear ends for easy extraction of coolant.

[0018] The drive assembly includes a motor 6, the bottom of which is fixedly connected to a rubber pad 5. An eccentric disc 7 is fixedly connected to the output end of the motor 6. A connecting rod 8 is rotatably connected to the outside of the eccentric disc 7. The top of the connecting rod 8 is connected to the bottom of the connecting seat 4. The drive assembly can drive the connecting seat 4 to rise and fall, thereby causing the diaphragm 3 to reciprocate up and down inside the pump body 1. The bottoms of the inlet pipe 13 and the outlet pipe 12 are both fixedly connected to the top of the sealing seat 2, facilitating the entry and exit of liquid from the pump body 1. Polyurethane foam 14 is placed on the outside of the drive assembly, serving to reduce noise. The end of the front suction pipe 18 passes through and is fixedly connected to the water tank 16. The end of the rear suction pipe 18 passes through the pump body 1 and is fixedly connected to the cooling pipe 15, serving to transport coolant. A return pipe 19 is fixedly connected to the lower end of the cooling pipe 15, and the return pipe 19 passes through the pump body 1 and is fixedly connected to the water tank 16, facilitating the return of coolant to the water tank 16. A semiconductor cooling chip 20 is fixedly connected to the outside of the water tank 16, and the cooling end of the semiconductor cooling chip 20 is connected to the water tank 16.

[0019] Working principle: When the motor 6 is started, the output end of the motor 6 drives the eccentric disk 7 to rotate. The rotation of the eccentric disk 7 causes the connecting rod 8, which is rotatably connected to its outer side, to reciprocate. Since the top of the connecting rod 8 is connected to the bottom of the connecting seat 4, and the middle of the connecting seat 4 is fixedly connected to the diaphragm 3, and the top of the diaphragm 3 is fixed to the bottom of the sealing seat 2, this causes the diaphragm 3 to reciprocate up and down inside the pump body 1. When the diaphragm 3 moves downward, the two channels 9 on the left side of the sealing seat 2 at the top of the pump body 1 are connected to the outside through the water inlet pipe 13. At this time, under the action of pressure difference, the external liquid enters the left chamber inside the pump body 1 through the water inlet pipe 13 and the channels 9, completing the liquid suction process. When the diaphragm 3 moves upward, the pressure inside the pump body 1 increases, and the two channels 9 on the right side are connected to the outside through the water outlet pipe 12. Under the pressure, the liquid is discharged from the pump body 1 through the channels 9 and the water outlet pipe 12, realizing liquid transportation. During the entire working process, the polyurethane foam 14 fixed on the inner wall of the pump body 1 plays a role in noise reduction. Since the operation of the motor 6 and the reciprocating motion of the diaphragm 3 generate noise, the polyurethane foam 14, with its porous structure, effectively reduces the noise generated inside the pump body 1 by allowing sound waves to enter the pores and rub against and collide with the internal structure when they reach it. Simultaneously, the rubber pad 5 at the bottom of the motor 6 absorbs the vibration energy generated by the motor 6 through its elasticity, reducing the transmission of vibration to the pump body 1 and the external environment, thus reducing low-frequency noise caused by vibration at its source. The water tank 16 at the front end of the pump body 1 stores coolant (such as pure water). When the semiconductor cooling chip 20, fixedly connected to the outside of the water tank 16, is energized, its cooling end quickly cools the coolant in the water tank 16. The water pump 17 at the top of the water tank 16 starts, drawing the low-temperature coolant from the water tank 16 through the front suction pipe 18, and then transporting the coolant to the cooling pipe 15 with a fixed wall thickness in the pump body 1 through the rear suction pipe 18. Cooling pipes 15 are distributed along the inner wall of the pump body 1, evenly absorbing heat generated inside the pump body 1 (including the drive components and pump chamber), thus raising the temperature of the coolant. The high-temperature coolant, after absorbing heat, flows back to the water tank 16 through the return pipe 19 at the lower end of the cooling pipes 15, and is cooled again by the semiconductor cooling chip 20, forming a closed-loop cooling cycle of "water tank 16 - water pump 17 - cooling pipes 15 - return pipe 19 - water tank 16". This cycle continues to operate, ensuring that the internal temperature of the pump body 1 is always maintained below 40℃, extending the service life of vulnerable components such as the diaphragm 3 and the sealing plate 11, and guaranteeing long-term stable operation of the equipment.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
