Asphalt cement mortar cart

Abstract

The invention relates to an asphalt cement slurry machine which comprises a chassis and a jacket; the jacket comprises a dry powder weighing and feeding assembly, an asphalt measurement and feeding assembly, a water measurement and feeding assembly, an additive measurement and feeding assembly, a stirring hose assembly, a slurry hold-over plate assembly, a power system and a control system; the additive measurement and feeding assembly comprises an additive storage tank, an additive feeding system, an additive filling system, an additive measurement device and a water filling system connectedwith the additive measurement device, which are subsequently connected together; the additive filling system comprises a liquid inlet bend pipe and a liquid filling control valve which are connected with the inlet end of the bottom of the additive measurement device; the water filling system comprises a water inlet pipe and a water filling control valve which are connected with an external water source; the water inlet pipe is connected with the inlet end at the bottom of the additive measurement device through a water inlet bend pipe; the liquid inlet bend pipe and the water inlet bend pipe are vertically arranged from down to top. The machine has the advantages of high automation degree, precise measurement, comprehensive functions, wide applicability, convenient operation and so on.

Description

technical field [0001] The invention mainly relates to the field of mortar equipment, in particular to an asphalt cement mortar truck. Background technique [0002] In the prior art, the ballastless track system is a new construction technology emerging for high-speed railways in recent years. The existing grouting equipment used as the gap filling material between the track slab and the base - the asphalt cement mortar vehicle has many shortcomings: [0003] 1. Mortar needs to be mixed during the building construction process. Various mortars include several components, and there are certain proportioning relationships between these components. These proportioning relationships must be followed during the mixing process, otherwise the mixed mortar will be Unable to meet construction requirements. Especially in the process of building high-speed railways, a special asphalt cement mortar (also known as CA mortar or BZM mortar) must be mixed, and the proportioning relationsh...

AI Technical Summary

Problems solved by technology

Therefore, in the prior art mortar truck admixture feeding and conveying system, when the outlet pressure of the admixture pump suddenly increases or the flow rate suddenly increases, overflow is required, and the overflow generally returns directly to the inlet pipe of the admixture pump; there is a certain pressure difference The overflow directly returns to the inlet of the admixture pump, and the heat generated by the overflow affects the working performance of the admixture pump to a certain extent

On the other hand, the amount of water reducer and defoamer stored in asphalt cement mortar trucks is relatively small in one cycle. A full box of water reducer generally takes 7 to 12 days to use, and a full box of defoamer lasts longer; The admixture in the construction environment has the phenomenon of precipitation and material segregation, which affects the quality of asphalt cement mortar
