Description

Technical Field

[0001] This utility model relates to the field of rotor pump technology, specifically a compact double-cam rotor pump. Background Technology

[0002] The double cam rotor pump, also known as a cam-type twin rotor pump or cam rotor pump, is a valveless, positive displacement positive displacement pump characterized by non-clogging, strong self-priming, forward and reverse rotation, corrosion and wear resistance, and the ability to transport gas-liquid-solid mixtures. The double cam rotor pump relies on two synchronously rotating rotors to generate suction (vacuum) at the inlet during rotation, thereby drawing in the material to be transported. The two rotors divide the rotor chamber into several small spaces, which operate in a specific sequence. As the rotors rotate, the medium in each small space is sequentially transported to the outlet.

[0003] Currently available dual-cam rotor pumps lack a self-lubricating structure, leading to insufficient lubrication of the gears during prolonged use. This dry friction generates high temperatures, accelerating gear wear and shortening the pump's lifespan. Furthermore, the absence of a cleaning mechanism in existing technology results in residual media in the pump chamber after shutdown, failing to meet the cleanliness requirements of industries such as food, pharmaceuticals, and high-purity chemicals. This affects the purity of the media transported in subsequent cycles and poses a risk of cross-contamination.

[0004] Therefore, this invention provides a compact double-cam rotor pump. Utility Model Content

The rotation of connecting shaft 326 drives gear 5 325 to rotate. The rotation of gear 5 325 drives the rotation of two gears 4 323. The rotation of the two gears 4 323 drives the rotation of two movable tubes 321. At the same time, it drives the limiting sealing ring sleeve 324 to rotate on the outer wall of the limiting sealing ring 335, which improves the stability and sealing of the rotation. The rotation of the two movable tubes 321 drives the two bent nozzles 322 to swing inside the mounting groove 1 314, thereby cleaning the inner wall of the conveying cavity in the double cam rotor pump 1, increasing the cleaning range. The waste liquid generated by cleaning will be discharged through the liquid outlet 44. After cleaning, the pneumatic push rod 48 is activated in reverse, so that the sealing baffle 43 moves into the inside of the connecting frame 42. At this time, the sealing baffle 43 seals the liquid outlet 44 inside the connecting frame 42, thereby sealing the front end of the conveying cavity in the double cam rotor pump 1 and reducing liquid leakage.
