Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention will be further described:

[0012] Referring to the accompanying drawings, the coil pump is mainly equipped with coil 1, flange 2, bearing 3, and seal 4, and the inner wall of the coil is provided with blades 1.1; Driven to rotate, during the process of passing through the coil cavity, the fluid gains acceleration under the thrust of the blades on the inner wall of the coil, and accelerates out of the pump body.

[0013] Although this invention was demonstrated in detail using the specific form, it is clear for those skilled in the art that various changes can be made without deviating from the intent and range of this invention.

Abstract

The invention relates to a rotary tube pump. The rotary tube pump is mainly provided with a rotary tube, a flange, a bearing and a sealing part, a blade is arranged on the inner wall of the rotary tube, and the rotary tube is erected on the outer wall of the flange through the bearing. The rotary tube pump is characterized in that the rotary tube and the flange are hollow cavities, and the flangeis directly connected with an external pipeline; the rotary tube rotates relative to the flange, the blade arranged on the inner wall of the rotary tube generates axial thrust while rotating, and fluid in the inner cavity of the rotary tube moves forwards under the function of thrust of the blade. The rotary tube pump is simple in structure, easy to manufacture, free of maintenance, and long in running time.

Description

technical field [0001] The invention relates to a momentum impurity pump, in particular to a coil pump. Background technique [0002] The rotary tube pump is a momentum impurity pump, which is suitable for conveying heterogeneous fluids containing solid impurities, especially for sewage treatment. At present, the impurity pumps used in the sewage treatment industry are equipped with impellers inside the pump body. Due to the large amount of various impurities in the sewage, the impellers are easily blocked when the sewage flows through the impellers, which affects the normal operation of the equipment. For this reason, it is necessary to propose a non-clogging impurity pump in structural space, which is used for transporting fluids containing various types of impurities. Contents of the invention [0003] The object of the present invention is to provide a coil pump to solve the above problems. The rotary tube pump has a simple structure, is easy to manufacture, has no b...
