Abstract

The invention discloses a vacuum suction material conveying pump system. The vacuum suction material conveying pump system comprises a pressure container, a vacuum slag suction unit and a positive pressure deslagging pumping unit, wherein the vacuum slag suction unit sucks slag into the pressure container through negative pressure, the positive pressure deslagging pumping unit is used for discharging the slag from the pressure container through positive pressure. According to the system, the vacuum suction overcomes the problems that manual work cannot be carried out in an effective space andlifting muck is difficult in the effective space, pneumatic conveying is applied to a shield machine, and a new conveying method satisfies the construction requirement and the construction cost is reduced; the air erosion situation generated in a material conveying process of a centrifugal pump is overcome, so that a large amount of energy consumption of a plunger pump in a high-pressure conveyingmode in the conveying process is overcome, the loss and large particle material conveying difficulty are caused due to the fact that a stator and a rotor are abrased in the material conveying processof a screw rod is overcome; and the certain problems in engineering construction and industrial application are solved.

Description

technical field [0001] The present invention relates to the technical field of pneumatic control, and is especially applicable to discharge operations of various liquids and solids where the space of the site is limited and where dregs or wastes cannot be handled manually, especially for discharge of various dregs such as clay and powder transportation on the roadheader Vacuum suction conveying pump system. Background technique [0002] For the various roadheaders currently used in tunnel construction in China, the soil transfer method usually adopts the rear matching marshalling train method to carry the slag or transport the pumping medium to the corresponding pumping station on the roadheader equipment for pumping the slag. There are not many pumping options selected by this transportation method on high-viscosity media, which not only increases the construction cost, but also greatly reduces the construction efficiency. In the case of limited space, most equipment is li...
