Description

Technical Field

[0001] The invention relates to the technical field of three-head peristaltic pumps, in particular to a heat-dissipating three-head peristaltic pump capable of double-sided output. Background Art

[0002] The three-head peristaltic pump is provided with two sets of pump heads at the upper end of the motor and one set of pump heads at the other end of the motor, which can improve the efficiency of the motor during transportation. However, it is easy to cause overheating of the pump body and the motor during use, and cooperate with the cooling structure to cool the motor and the pump body. However, there are still some problems with the existing three-head peristaltic pump cooling structure.

[0003] In the prior art, the authorization disclosure (announcement) number: CN209212522U in "A multi-channel peristaltic pump" discloses a multi-channel peristaltic pump, including a first fixed plate, a housing, a circuit board and a fan, a second fixed plate is provided above the fan, the second fixed plate is fixed above the fan by a second bolt, a solenoid valve is fixed to the upper surface of the second fixed plate by a second bolt thread, a heat dissipation hole is provided on the surface of the circuit board in the housing that is different from the fan, a power interface is provided on the surface of the housing below the heat dissipation hole, a roller is fixed on the upper surface of the first fixed plate, a transmission wheel is connected to one end of the roller, a pressure plate is movably installed above the roller, a pipeline slot is provided on the end face of the housing on the side of the pressure plate away from the circuit board, and a spring self-locking switch is provided inside the housing on the side of the pressure plate away from the transmission wheel. The utility model has the advantages of being provided with a solenoid valve, which can automatically switch the pipeline path inside the peristaltic pump, and automatically switch the pipelines of reagents and cleaning fluids, thereby shortening the cleaning time of the peristaltic pump pipeline;

[0004] During the operation of the above device, by setting a transmission wheel, the power of the motor is transmitted to the roller through the transmission wheel, and then the roller and the pressure plate squeeze and divert the pipeline to control the flow of the liquid in the pipeline. The peristaltic pump is like pinching a hose full of fluid with your fingers, and the fluid in the tube moves forward as the fingers slide forward. The peristaltic pump is also based on this principle, but the fingers are replaced by rollers. The fluid is pumped by alternately squeezing and releasing the elastic delivery hose of the pump. Just like pinching a hose with two fingers, as the fingers move, negative pressure is formed in the tube, and the liquid flows accordingly. However, it is convenient to cool the pipeline of the peristaltic dry process during use, which leads to more serious heat generated by the friction of the outer shell of the pump body.

[0005] In addition, in the prior art, the authorization disclosure (announcement) number: CN213540681 U in “A liquid glue peristaltic pump driver heat dissipation device”, wherein the utility model discloses a liquid glue peristaltic pump driver heat dissipation device, including a cooling ring, the cooling ring is provided with a tightening mechanism for realizing the installation and tightening of the cooling ring, the cooling ring is provided with a buffer block mechanism for realizing the clamping and fixing of the cooling ring and the liquid glue peristaltic pump driver installation part, and the cooling ring is provided with a circulating fan blade mechanism for realizing the heat dissipation effect of the cooling ring on the liquid glue peristaltic pump driver. The utility model has a reasonable structure, and liquid heat dissipation of the peristaltic pump driver is realized by setting a circulating fan blade mechanism, and the circulation process of the cooling liquid is realized in conjunction with the water inlet pipe and the water outlet pipe, so as to realize the improvement of the heat dissipation efficiency of the peristaltic pump driver, and prevent the peristaltic pump driver from being overheated and affecting the normal use of the peristaltic pump driver and the liquid glue delivery process;

[0006] During the operation of the above-mentioned device, a circulating fan blade mechanism is provided to realize liquid heat dissipation of the peristaltic pump driver, and the water inlet pipe and the water outlet pipe are cooperated to realize the circulation process of the cooling liquid, thereby improving the heat dissipation efficiency of the peristaltic pump driver and preventing the peristaltic pump driver from overheating and affecting the normal use of the peristaltic pump driver and the delivery process of the liquid glue. The tightening mechanism and the buffer block mechanism are provided to realize convenient installation and tightening between the device and the peristaltic pump driver, and convenient fixing and disassembly of the device and the peristaltic pump driver. However, when in use, the liquid heat dissipation is provided and the peristaltic pump is easily damaged when a pipe leaks. Summary of the invention
