Description

Technical Field

[0001] The utility model relates to the technical field of screw pumps, in particular to a screw pump for asphalt transportation. Background Art

[0002] A screw pump, also known as a screw pump, a screw pump or an Archimedean screw pump, is a pump that uses the rotation of a spiral blade to cause water to rise in an axial spiral shape. It is mainly composed of a shaft, a spiral blade and a casing. When pumping water, the pump is placed obliquely in the water so that the inclination angle of the main shaft of the water pump is smaller than the inclination angle of the spiral blade, and the lower end of the spiral blade contacts the water. When the prime mover drives the screw pump shaft to rotate through the speed change device, water enters the blade and rises along the spiral flow channel until it flows out.

[0003] For example, the announcement number CN204419722U is called a shock-proof screw pump, which includes a screw pump body. A shock-absorbing device is provided at the lower end of the screw pump body. The shock-absorbing device includes a bottom shell box and an upper cover plate. A plurality of fixing rods are fixed in the bottom shell box. The upper cover plate is provided with a plug-in rod that matches the fixing rod. The plug-in rod is plugged into the fixing rod. A spring is connected between the fixing rod and the plug-in rod. The upper cover plate is fixedly connected to the screw pump body.

[0004] During the use of the above device, the heat conduction efficiency is low. When the equipment is shut down and restarted, the asphalt needs to be melted by the heat conduction plate before starting the screw pump, which is inefficient. Therefore, we proposed a screw pump for asphalt transportation to solve the above problems. Utility Model Content
