Novel horizontal double-screw pump

Abstract

The invention relates to the technical field of double-screw pumps, in particular to a novel horizontal double-screw pump. The technical problem to be solved by the invention is that dust or gravel impurities can easily enter into a pump from a vertical outlet. In order to solve the technical problem, the invention provides a novel horizontal double-screw pump which comprises a pump body, the right side of the front side of the pump body communicates with one end of a feeding pipe, the right side of the top of the pump body communicates with one end of a discharging pipe, two sides of the bottom of the inner wall of the discharging pipe are connected with two ends of a connecting rod respectively, and the middle position of the top of the connecting rod is connected with the bottom of a telescopic rod. According to the novel horizontal double-screw pump, the discharging pipe is improved, when the pump body is not used, a dustproof plate is restored to the initial position through elastic acting force of a reset spring, so that the discharging pipe is blocked, the phenomenon that the dust or the gravel impurities enter into the pump body from the vertical outlet is avoided, the internal cleaning of the double-screw pump is guaranteed, and the normal service life of the double-screw pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of twin-screw pumps, in particular to a novel horizontal twin-screw pump. Background technique [0002] The twin-screw pump is a sealed chamber with a constant volume formed between the screw sleeve and the pump body or bushing on the main and driven shafts, and the medium is sent to the middle of the pump body with the rotation of the screw shaft, and the two meet together. Finally, it is delivered to the outlet of the pump, so as to achieve the purpose of pump delivery. [0003] During the use of the twin-screw pump, it is mainly used to transport not only the medium with good lubricity, but also a large amount of non-lubricating medium, medium with various viscosities (the highest viscosity can reach 3*106mm / s) and corrosive Sexual (acid, alkali, etc.), abrasive liquid. In addition to conveying pure liquid, it can also convey a mixture of gas and liquid, that is, mixed vapor and liquid, which is also on...
