Abstract
An annular slurry mixing device for a combined wet-type concrete spraying machine comprises a main pipeline, a branch pipeline and a shell, the shell is arranged on the main pipeline in a sleeving mode, and the inner wall of the shell is matched with the outer wall of the main pipeline in a sealed mode to form an annular sealed working chamber, namely, a slurry flow chamber; the branch pipeline is installed on the shell and communicated with the slurry flow chamber, and a plurality of connecting holes which are evenly distributed in the periphery of the main pipeline and used for communicating the slurry flow chamber with the main pipeline are formed in the main pipeline; one end of the main pipeline is communicated with a dried material conveying pipe of the concrete spraying machine, a spray nozzle is installed at the other end of the main pipeline, and the branch pipeline is communicated with a slurry conveying pipe of the concrete spraying machine. By means of the annular slurry mixing device for the combined wet-type concrete spraying machine, mixing of slurry is conducted before the slurry enters the spray nozzle to be sprayed out, and meanwhile multiple connecting holes are formed in the interior of the annular slurry mixing machine, so that the slurry is evenly sprayed around dried materials in the main pipeline, even mixing of the slurry and the dried materials is convenient, and the use effect after spraying is improved.
Description
Technical field
The present invention relates to a kind of concrete injection device, the ring-type especially relating to a kind of combined wet-type concrete sprayer mixes sizing device.
Background technology
Concrete sprayer is to mine working, the capital equipment of concrete ejection is carried out in the places such as tunnel, compressed air is mainly utilized to be ejected in working face by coagulation degree, existing spraying machine is mainly divided into siccative spraying machine and wet feed spraying machine, but all there is very large problem in two kinds of spraying machines, siccative spraying machine easily forms a large amount of dust polluting environments in course of injection, wet feed spraying machine is easy frozen plug pipeline in course of injection, and the problem that the existing dry wet spraying machine combined still easily causes pipeline blockage because pipeline is oversize, easily cause mixing uneven simultaneously, affect construction effect.
Summary of the invention
The object of the invention is to use inconvenient for solving existing spraying machine, easily causing frozen plug because pipeline is long and mixing the uneven problem affecting construction effect, providing a kind of ring-type of combined wet-type concrete sprayer to mix sizing device.
The present invention is the deficiency solved the problems of the technologies described above, and the technical scheme adopted is:
A kind of ring-type of combined wet-type concrete sprayer mixes sizing device, comprise main pipeline, branch pipe(tube) and shell, casing is located on main pipeline, outer casing inner wall and main pipeline outer wall are sealed and matched and form the pressurization working lumen of annular, sealing working chamber is pulp flow chamber, branch pipe(tube) is arranged on shell and branch pipe(tube) is communicated with pulp flow chamber, main pipeline offers a plurality of connecting hole for being communicated with main pipeline in pulp flow chamber distributed along its even circumferential, one end of main pipeline is communicated with the siccative carrier pipe of described concrete sprayer, the other end is provided with injector head, subtube is communicated with the fluid-conveying pipe of described concrete sprayer.
The excircle of described main pipeline is provided with baffle ring I spaced apart and baffle ring II, and the diameter of baffle ring I is less than the diameter of baffle ring II, shell is the sleeve that an inside offers shoulder hole, casing is located at the outside of main pipeline upper baffle ring I and baffle ring II, by the pulp flow chamber formed between three that is sealed and matched of baffle ring I, baffle ring II and outer casing inner wall.
Described baffle ring I and baffle ring II and housing contacts face are all provided with joint ring.
The invention has the beneficial effects as follows: the ring-type mortar mixer of the present invention by arranging, slurry was mixed before entering injector head ejection, can effectively avoid, produce dust, avoid the material frozen plug pipeline that too early mixing causes simultaneously, ring-type mixes sizing device, siccative and slurry are here mixed on limit, then sprayed by shower nozzle, ring-type mortar mixer inside is provided with a plurality of connecting hole simultaneously, and along the circle distribution of main pipeline, the surrounding of the siccative in main pipeline is so just made to spray slurry uniformly, be convenient to slurry and siccative are mixed, improve the result of use after spraying.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Graphical indicia: 1, shell; 2, branch pipe(tube); 3, pulp flow chamber; 4, baffle ring II; 5, connecting hole; 6, joint ring; 7, upper baffle ring I; 8, main pipeline.
Detailed description of the invention
Shown in Fig. 1, detailed description of the invention is as follows:
A kind of ring-type of combined wet-type concrete sprayer mixes sizing device, comprise main pipeline 8, branch pipe(tube) 2 and shell 1, shell 1 is set on main pipeline 8, shell 1 inwall and main pipeline outer wall are sealed and matched and form the pressurization working lumen of annular, sealing working chamber is pulp flow chamber 3, branch pipe(tube) 2 is arranged on shell 1 and branch pipe(tube) 2 is communicated with pulp flow chamber 3, main pipeline 8 offers a plurality of connecting hole 5 for being communicated with main pipeline 8 in pulp flow chamber 3 distributed along its even circumferential, one end of main pipeline 8 is communicated with the siccative carrier pipe of described concrete sprayer, the other end is provided with injector head, subtube 2 is communicated with the fluid-conveying pipe of described concrete sprayer.
The excircle of described main pipeline 8 is provided with baffle ring I7 spaced apart and baffle ring II4, and the diameter of baffle ring I7 is less than the diameter of baffle ring II4, shell 1 is the sleeve that an inside offers shoulder hole, shell 1 is set in the outside of main pipeline 8 upper baffle ring I7 and baffle ring II4, by the pulp flow chamber 3 formed between three that is sealed and matched of baffle ring I7, baffle ring II4 and shell 1 inwall.
Described baffle ring I7 and baffle ring II4 and shell 1 contact surface are all provided with joint ring 6.
The present invention in use, now shift siccative conveyer and slurry agitation conveyer onto correct position, then the present invention be arranged on injector head front and be connected to siccative mixer and pulp blender, drive siccative mixer and pulp blender work, all be sent to ring-type mortar mixer by after siccative and slurry mixing, spray after mixing inside mortar mixer.
Technical scheme cited by the present invention and embodiment be not restriction, be equal to the technical scheme cited by the present invention and embodiment or effect same approach all in the scope that the present invention protects.
