Example Embodiment

[0035] Example one:

[0036] Such as figure 1 The shown mud pump includes a frame 1, a pumping unit 2, a screw mud pressing unit 3, and a mud mixing unit 4. The following is a detailed description of each unit:

[0037] The frame 1 can be used for supporting work or for mobile transition.

[0038] The pumping unit 2 is arranged on the frame 1. The pumping unit 2 includes a pumping hopper 20, a mud tank 21 communicating with the pumping hopper 20, a water tank 22 communicating with the mud tank 21, and a connection between the pumping hopper 20 and the mud. The distribution reversing valve 23 of the cylinder 21 and the pumping power assembly for pumping out the mud in the mud cylinder 21. Such as figure 1 Shown: the pumping direction of the pumping unit 2 in this embodiment is horizontally pumped from left to right. Among them: the distribution reversing valve 23 is an S-pipe type distribution valve; the pumping power components are the oil cylinder 24 and the piston 25; the mud cy...

Example Embodiment

[0045] Embodiment two:

[0046] Such as figure 2 It is shown that this embodiment is basically the same as the first embodiment, and the difference is that: in this embodiment: the distribution reversing valve 23 adopts a butterfly valve or a cone valve or a ball valve or a gate valve.

Example Embodiment

[0047] Embodiment three:

[0048] Such as image 3 Shown: this embodiment is basically the same as the first embodiment, the difference is: in this embodiment: the screw mud pressing unit 3 is arranged on the side of the pumping unit 2, and the discharge port of the mud pressing hopper is opened in the pressurizing The side of the feed section 302.

Abstract

The invention relates to a paste pump which comprises a rack, a pumping unit, a spiral paste pressing unit and a paste stirring unit. The pumping unit comprises a pumping hopper. The spiral paste pressing unit comprises a paste pressing hopper, a paste pressing shaft, a spiral blade and a paste pressing drive component, and the paste pressing hopper communicates with the pumping hopper. The paste stirring unit comprises a stirring hopper, a stirring shaft, a stirring blade and a stirring drive component, and the stirring hopper communicates with the paste pressing hopper. According to the paste pump, the pumping efficiency is high, and high-viscosity pasty objects with the water content being 30% or above can be pumped; the whole processes of preparing, pressing and pumping are completed in the same machine body, the requirements for manpower and sites are reduced, the paste pump can be used for the ground or directly enter the construction site in a tunnel, and the long-distance conveying link, materials and energy consumption are reduced; and the inertial thinking that two hoppers need to be separated by a physical plate-type discharging door is broken through, the dual functions of door separation and pressing are achieved through spiral rotating and stopping, the three functional hoppers are communicated without obstacles, the whole machine structure is simple, and functions are complete.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a mud pump. Background technique [0002] In the construction of underground trenchless projects such as subways, underground pipe galleries, and underground passages, pipe jacking machines and shield machines are often used for construction. When such equipment is constructed underground, due to the influence of the self-weight of (supporting) concrete prefabricated pipe joints or machine self-weight , when the geological conditions change along with the line, it will often cause geological subsidence, resulting in the problem that the actual construction direction deviates from the set direction, and the problem of filling the gap between the excavation space and the concrete structure. [0003] In order to solve the above problems, a grouting pump is usually used at present to inject mud into the outer end of the concrete prefabricated pipe joint wall at the settlement th...
