Description
Technical field
The present invention relates to a kind of grouting pump, relate in particular to a kind of in coal mining, constructing tunnel industry, for gas sealing of hole, grouting and reinforcing, in the situation that not needing detaching equipment, can conveniently clean the pump housing and peripheral pipeline, there is the pneumatic Double-liquid mud-injection pump with self-cleaning function of the features such as volume is little, lightweight, cleaning is easy, failure rate is low, pulp ratio is accurate, slip casting effect is desirable.
Background technology
In the process of coal mining or constructing tunnel, often want gas sealing of hole, grouting and reinforcing, need to use Double-liquid mud-injection pump, existing Double-liquid mud-injection pump does not have conventionally can the quick and easy cleaning pump housing and the self-cleaning assembly of pipeline, due to the particularity of two fluid grouting pump structure and service condition, after two kinds of liquid in pipeline mix, be swift in response, and the two mixes at the front end of total pulp pipeline under normal circumstances, need to discharge and use in time. for the raw material that avoid waste, in conversion slip casting position, telephone-moving, need temporary close grouting pump, within this period, the biliquid hydrid component of grouting pump and total grout outlet route cannot be discharged completely in the mixed slurry of inside, can form rapidly in inside obturator, and external detergent line be cleared up or be accessed on the pipeline of grouting pump to existing Double-liquid mud-injection pump can only by removing these parts that have obturator, and be filled with cleansing medium and clean, these operations are conventionally consuming time longer, waste of manpower and man-hour, and also can retention portion divide cleansing medium and residue in the pipeline after cleaning, these cleansing mediums or residue reuse Shi Huiyu at grouting pump and mix rear slurry generation reaction, after impact mixes, the physicochemical properties of slurry, cause shutoff, consolidation effect variation. for this reason, user conversion slip casting position, telephone-moving time consider and reduce manpower, expenditure of time, reduce production costs, conventionally Double-liquid mud-injection pump is not cleaned, and only after a complete grouting with plunger, just carry out above-mentioned cleaning completing, this just causes after slip casting interval repeatedly, in biliquid hydrid component and total pulp pipeline, can stockpile curing biliquid mixture, stop up biliquid hydrid component and total pulp pipeline, reduce the pulp efficiency of grouting pump, make its fault rate raise simultaneously, after a complete grouting with plunger finishes, when whole grouting pump is cleaned, or can only clear up or access external detergent line on the pipeline of grouting pump by removing these parts that have obturator, and be filled with cleansing medium and clean, still to consume a large amount of costs of labor, because biliquid hydrid component and the long-pending curing biliquid mixture of total pulp pipeline internal memory too much cause thoroughly cleaning, can only change biliquid hydrid component and total pulp pipeline, cause the increase of existing Double-liquid mud-injection pump use cost, and in the time that grouting pump is split to cleaning, unmixing two kinds of liquid in the pump housing can only directly be discharged, cause the waste of raw materials for production.
In a word, existing Double-liquid mud-injection pump can the quick and easy cleaning pump housing and the self-cleaning assembly of pipeline owing to not having, and therefore exists easily and stops up, and fault rate is high, and service efficiency is low, cleans difficulty, labor intensive, the defect that use cost is high.
