Abstract
The invention discloses a double-liquid grouting mixer, which comprises a tubular shell with a mixing cavity, wherein one end of the shell is provided with a first inlet through which one kind of liquid can flow into the mixing cavity; a connection pipe through which the other liquid flows towards the mixing cavity is arranged at the other end of the shell; a core pipe is communicated with one end, which stretches into the mixing cavity, of the connection pipe; one end, which is close to the first inlet, of the core pipe is closed; through holes are formed in the side wall of the core pipe; a core ball and a jacking spring which can push the core ball to block an outlet of the connection pipe are arranged in the core pipe; and an outlet through which mixed liquid is sprayed is formed in the middle of the shell. By the double-liquid grouting mixer, water glass and cement slurry can be mixed under the condition that the pressure of the water glass is greater than elastic force of the jacking spring, and a phenomenon that the pressure of the water glass is required to be greater than that of the cement slurry in the prior art is avoided, so that the double-liquid grouting mixer is relatively wide in application range and can be used in a relatively wide pressure range.
Description
Technical field
The present invention relates to and a kind ofly the liquid of two kinds of construction materials can be starched mixed uniformly blender.
Background technology
Bi-slurry grouting method injects soil and quick solidification after a kind of material by two kinds of liquid pulpous state states (as waterglass and cement mortar) mixes according to a certain percentage, with the arrangement and method for construction of the intensity and bearing capacity that improve soil, it is widely used in the engineerings such as sealing leak stopping, foundation stabilization.And in the process of two fluid grouting, can the material of two kinds of liquid pulpous state states mix smoothly in a mixer and mix the quality directly affecting two fluid grouting.
Traditional double liquid grout injecting mixer is three-port structure, the deficiency of this blender is: when two strands of liquid slurries are under the conveying of respective induction system, the process mixed is carried out in the inside of spirt threeway, these the two strands liquid slurries that flowing is also impacted mutually in opposite directions can produce turbulent flow, be difficult to the match ratio accurately controlling two kinds of liquid slurries, and mix uneven, the mixed liquor slurry making mixing inject soil afterwards cannot reach the effect of rapid solidification, the quality of the whole construction work of final impact; In addition, two strands of liquid slurries in three-way pipe are under the fluctuation of pressure, wherein one liquid slurry easily enters the carrier pipe (be generally cement mortar and flow to waterglass carrier pipe) of another strand of liquid slurry at the flows by action of larger pressure, and starch to mix with another strand of liquid and solidify, cause the carrier pipe of another strand of liquid slurry blocked and the hybrid working of two kinds of liquid slurries cannot be proceeded.
For this reason, what China Patent Publication No. was " CN 101892847 A " application discloses a kind of novel double liquid grout injecting mixer, it comprises vertically arranging starches injection for a kind of liquid, and the liquid that upper end is provided with the hybrid chamber communicated with it is starched and is managed, and manage through another liquid slurry that described liquid slurry pipe stretches in hybrid chamber, described another liquid slurry pipe upper end closed, lower end is provided with the import of injecting for another kind of liquid slurry, the sidewall on another liquid slurry pipe top has through hole, the sidewall sheath of another liquid slurry pipe has the elastic caoutchouc cover that can cover through hole, in the process implemented, cement mortar and waterglass is injected respectively toward liquid slurry pipe and another liquid slurry pipe, when the pressure of waterglass reaches more than predetermined value, elastic caoutchouc cover can be strutted, and flow to hybrid chamber along the gap that the lateral wall of the rubber sleeve after softened and another kind of liquid slurry pipe is formed and mix, thus prevent from producing turbulent flow and affecting mixed effect when waterglass and cement mortar mixing, and prevent in the carrier pipe of cement mortar inflow waterglass, the situation of waterglass pipe frozen plug is caused to occur.
But this novel double liquid grout injecting mixer still has weak point, its reason is, in the process implemented, the pressure of waterglass must be greater than the pressure (description the 14th section of last two rows see this application) of cement mortar, otherwise, waterglass cannot flow out from the through hole of another liquid slurry pipe, and spray into hybrid chamber along the gap that the lateral wall of the rubber sleeve after softened and another kind of liquid slurry pipe is formed.And in the work progress of reality, different engineerings has different requirements to the mixing ratio that two strands of liquid are starched, and mixing ratio and the pressure of waterglass and cement mortar have direct relation, so, for meeting various demand, ensure that double liquid grout injecting mixer can be greater than at the pressure of waterglass with regard to needing, when being equal to or less than the pressure of cement mortar, waterglass all can enter hybrid chamber and mix with cement mortar, but obviously, the novel double liquid grout injecting mixer of this application only just can carry out the mixing of two strands of liquid slurries when the pressure of waterglass is greater than the pressure of cement mortar, instructions for use cannot be met.
Summary of the invention
The object of the present invention is to provide a kind of double liquid grout injecting mixer, it can carry out the hybrid working of two kinds of liquid slurries in a larger pressure limit.
A kind of double liquid grout injecting mixer of the present invention, comprise the shell of the tubulose with hybrid chamber, it is characterized in that: one end of described shell is provided with the first entrance flowing into hybrid chamber for a kind of liquid slurry, the other end of shell is provided with the tube connector flowing to hybrid chamber for another kind of liquid slurry, one end that tube connector stretches into hybrid chamber is led to core pipe, core pipe is closed near one end of the first entrance, the sidewall of core pipe has through hole, the inside of core pipe is provided with core ball and can promotes the top spring that the outlet of tube connector blocks by core ball, the middle part of shell is then provided with the outlet for mixed slurries ejection.
The present invention stretches into the hybrid chamber of shell part at tube connector leads to the core pipe having its one end near the first entrance to close, and offer through hole at the sidewall of core pipe, be provided with core ball in the inside of core pipe and the top spring that the outlet of tube connector blocks by core ball can be promoted, when the pressure not injecting the waterglass of waterglass or injection toward tube connector is less than the elastic force of top spring, core ball is owing to pushing up the effect of spring by the path blockade of tube connector, can prevent cement mortar from flowing into tube connector and waterglass carrier pipe, and when needing two kinds of liquid slurries to mix, waterglass and cement mortar is injected respectively toward tube connector and the first entrance, when the pressure of waterglass is greater than the elastic force of top spring, the core ball blocking tube connector outlet is pushed open by waterglass, the path of tube connector is opened, now, waterglass flows into core pipe from tube connector, and flow into hybrid chamber from the through hole of core pipe, mix with cement mortar, and due to the injection direction of the waterglass sprayed from through hole substantially vertical with flowing to of the cement mortar injected from the first entrance, so can not turbulent flow be produced when waterglass and cement mortar mixing, mixed effect can be ensured, obviously, the present invention, only need ensureing that the pressure of waterglass is greater than the hybrid working that the elastic force of pushing up spring can carry out waterglass and cement mortar, and do not need as prior art, need to ensure that the pressure of waterglass is greater than the pressure of cement mortar, as can be seen here, the scope of application of the present invention is wider, can use in a larger pressure limit.
