Description

Technical Field

[0001] This utility model relates to the technical field of single screw pump equipment, and in particular to a single screw pump with high heat dissipation. Background Technology

[0002] A screw pump is a positive displacement rotary pump that transports or pressurizes liquids by relying on the changing volume and movement of the meshing space formed by the pump body and the screw. The working principle of a screw pump is to use the rotation of the screw to draw in and discharge liquids. Due to the meshing of the screws and the tight fit between the screw and the inner wall of the bushing, one or more sealed spaces are created between the pump's suction and discharge ports. As the screw rotates and meshes, these sealed spaces are continuously formed at the pump's suction end, sealing the liquid in the suction chamber within them. The liquid is then continuously pushed from the suction chamber along the screw's axial direction to the discharge end, continuously discharging the liquid enclosed in each space, much like a nut continuously moving forward as the screw threads rotate. Screw pumps offer good economic performance, high and uniform pressure, uniform flow, high speed, and can be directly coupled to a prime mover. Screw pumps can transport various oils and high molecular polymers.

[0003] Screw pumps can be classified into single-screw pumps, twin-screw pumps, and triple-screw pumps according to the number of screws. Due to the special geometry of the rotor and stator, single-screw pumps form separate sealed cavities, making them suitable for conveying high-viscosity fluids and media containing hard suspended particles or fibers. However, in existing single-screw pumps, friction occurs between the screw and the screw sleeve during operation, generating a large amount of heat. This heat accumulates in the cavity, and because the cavity is relatively sealed during use, the heat cannot be easily dissipated directly. This makes it difficult for the screw and screw sleeve to dissipate heat and cool down, causing the pump body temperature to rise and affecting its operation. Utility Model Content

[0004] The purpose of this invention is to solve the problem of poor heat dissipation and inconvenient heat dissipation of existing single screw pumps during use, and to propose a single screw pump with high heat dissipation performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high heat dissipation single screw pump includes a base plate, a mounting housing fixedly connected to the top of the base plate, an inlet end and an outlet end fixedly connected to the outer side wall of the mounting housing, a screw inside the mounting housing, a drive mechanism for driving the screw to rotate on the base plate, a mounting sleeve adapted to the screw fixedly connected to the inner side wall of the mounting housing, and a heat dissipation mechanism inside the mounting sleeve.

[0007] Preferably, the drive mechanism includes a motor fixedly connected to the top of the base plate, a transmission assembly is rotatably connected through the mounting housing, the motor output shaft and the transmission assembly are fixedly connected by a coupling, the outer side wall of the transmission assembly away from the motor is fixedly connected to the outer side wall of the screw, and a sealing assembly is provided on the outer side wall of the transmission assembly.

[0008] Preferably, the heat dissipation mechanism includes a heat dissipation cavity opened inside the mounting sleeve, a plurality of heat-absorbing blocks are fixedly connected to the inner sidewall of the heat dissipation cavity, a first coolant is provided on the inner sidewall of the heat dissipation cavity, a heat-conducting block is fixedly connected to the outer sidewall of the heat-absorbing block, and the outer sidewall of the heat-conducting block away from the heat-absorbing block passes through the heat dissipation cavity and the mounting shell and is connected to a cooling mechanism.

[0009] Preferably, the cooling mechanism includes a mounting box fixedly connected to the top of the base plate. The mounting box is arranged in a ring shape and is fitted outside the mounting shell. Multiple heat sinks are fixedly connected to the outer wall of the heat-conducting block, and the multiple heat sinks all penetrate the mounting box and extend inward.

[0010] Preferably, a second coolant is provided inside the mounting box, and a cooling device is fixedly connected to the top of the mounting box.

[0011] Preferably, a sealing rubber gasket is fixedly sleeved on the outer wall of the heat-conducting block, and the outer wall of the sealing rubber gasket is in close contact with the inner wall of the mounting box.

[0012] The beneficial effects of this utility model are as follows:

[0013] The combined use of the heat dissipation chamber, the first coolant, and the heat absorption block allows the mounting sleeve to easily absorb the heat generated by friction. Then, the heat is transferred to the outside of the mounting housing through the setting of the heat conduction block, reducing the temperature inside the mounting housing and facilitating heat dissipation and cooling of the screw and mounting sleeve. At the same time, the combined use of the mounting box, the second coolant, and the heat sink cools the discharged heat, preventing heat from accumulating on the outside of the mounting housing. In addition, the use of the cooling device allows the mounting box to cool the discharged heat for a long time, facilitating long-term heat dissipation work and improving the overall heat dissipation performance of the single screw pump.
