Abstract
This utility model relates to a kind of special-shaped concrete ejection shower nozzle, relates to gunite concrete apparatus field.It is uneven that purpose is to solve existing shower nozzle gunite concrete material component, causes rebound of shotcrete to strengthen, and dust pollution is serious, and gunite concrete later strength is not enough, the problem that construction benefit is low.Shower nozzle described in the utility model includes spray chamber and special-shaped chamber, and described spray chamber is the cavity that diameter is gradually reduced, and one end that diameter is big is conveying end, and the conveying pipeline outside connection, one end that diameter is little is shower nozzle spout；The middle part of spray chamber is provided with special-shaped chamber, and the material of conveying carries out secondary mix and blend in special-shaped chamber.This utility model increases one or more special-shaped chamber on the basis of traditional sprinkler heads, concrete ejection material is made to be entered spray chamber by slurry-feeding hole, by spray chamber, jetting material is ejected into by the process having secondary to mix before spray plane again, under the conditions of avoiding conventional spray concrete technology, the mixing of each component is uneven, affects the drawback of later strength.
Description
Technical field
This utility model relates to gunite concrete apparatus field.
Background technology
At present, in shotcrete construction both domestic and external, spray the design of shower nozzle and apply all hollow cylinders to tie
Structure.During construction, material will necessarily occur the secondary separation such as aggregate and cement existing during conveying mechanism and conveyance conduit thereof
As, after causing injection, concrete materials component is uneven so that rebound of shotcrete strengthens, and dust pollution is serious, and injection is mixed
Solidifying soil later strength is not enough, and construction benefit is low.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of special-shaped concrete ejection shower nozzle, it is therefore intended that solve
Existing shower nozzle gunite concrete material component is uneven, causes rebound of shotcrete to strengthen, and dust pollution is serious, sprays coagulation
Soil later strength is not enough, the problem that construction benefit is low.
The technical scheme that this utility model solves above-mentioned technical problem is as follows: a kind of special-shaped concrete ejection shower nozzle, its bag
Including spray chamber and special-shaped chamber, described spray chamber is circular cylindrical cavity, and one end of described spray chamber is conveying end, connect outside defeated
Material pipe, the other end is shower nozzle spout, and the diameter of spray chamber is gradually reduced to shower nozzle spout from conveying end；The middle part of spray chamber sets
Having special-shaped chamber, the material of conveying carries out secondary mix and blend in special-shaped chamber.
The beneficial effects of the utility model are: this utility model effectively prevent dry spray and wet shot thing by increasing special-shaped chamber
Scattered defect before material ejection, both can reduce release and the generation of job site dust, after can reducing again material injection
Bounce-back, improves sprayed construction effect.Effectively reduce dust in course of injection by the secondary of material is mixed, reduce resilience, with
Time reduce prop later strength loss, it is ensured that the safety of prop.
On the basis of technique scheme, this utility model can also do following improvement.
Further, described special-shaped chamber is one or more.
Further, described special-shaped chamber is spherical, square or a combination of both.
Further, the material of described conveying is any form of Gunning material that any proportioning is formed.
Further, the material of described conveying forms cyclone in special-shaped chamber and carries out secondary mix and blend.
Further, the conveying end of described spray chamber is provided with slurry-feeding hole.
Further, the end of the conveying end of described spray chamber is provided with rubber sleave.
Further, a length of 500mm-1500mm of described spray chamber.
Further, a diameter of 60mm-80mm of described spray chamber.
Further, when special-shaped chamber is spherical, its a diameter of 80mm-150mm.
Accompanying drawing explanation
Fig. 1 is the structural representation of special-shaped concrete ejection shower nozzle described in the utility model.
In accompanying drawing, the list of parts representated by each label is as follows:
1, spray chamber, 2, special-shaped chamber, 3, slurry-feeding hole, 4, rubber sleave.
Detailed description of the invention
Being described principle of the present utility model and feature below in conjunction with accompanying drawing, example is served only for explaining this practicality
Novel, it is not intended to limit scope of the present utility model.
Embodiment 1
As it is shown in figure 1, the present embodiment proposes a kind of special-shaped concrete ejection shower nozzle, this shower nozzle includes spray chamber 1 and different
Die cavity 2, described spray chamber 1 is circular cylindrical cavity, and one end of described spray chamber 1 is conveying end, the conveying pipeline outside connection, another
End is shower nozzle spout, and the diameter of spray chamber 1 is gradually reduced to shower nozzle spout from conveying end；The middle part of spray chamber 1 is provided with abnormal shape
Chamber 2, the material of conveying carries out secondary mix and blend in special-shaped chamber 2.
The present embodiment, by concrete ejection shower nozzle is redesigned and processed, increases on the basis of traditional sprinkler heads
One or more special-shaped chambeies 2 so that concrete ejection material is being entered spray chamber 1 by slurry-feeding hole 3, then will injection by spray chamber 1
Material is ejected into by the process having secondary to mix before spray plane, it is to avoid under the conditions of conventional spray concrete technology, each component mixes not
Uniformly, the drawback of later strength is affected.
Meanwhile, in order to make shower nozzle and outside conveying pipeline realize sealing and solid connection, at the conveying end of spray chamber 1
End rubber sleave 4 is set.
In order to obtain the effect of more preferable secondary mix and blend, the structure in special-shaped chamber 2 can be transformed, make defeated
The material sent can form cyclone in special-shaped chamber 2, thus realizes more preferable secondary mix and blend.
Preferably, a length of 500mm-1500mm of described spray chamber 1；A diameter of 60mm-80mm of described spray chamber 1；
When special-shaped chamber 2 is spherical, its a diameter of 80mm-150mm.
Nozzle structure described in the utility model can reach depositing dust, reduce rebound degree and the purpose of environmental pollution, permissible
It is widely used in replacing the shower nozzle of the multiple industry gunite concrete equipment such as foundation ditch, building strengthening, colliery, tunnel.
Use shower nozzle described in the utility model can accelerate material secondary stirring, reduce feed separation phenomenon, hence it is evident that fall
Low dust concentration, protects environment, improves work efficiency, reduces labor intensity, improves construction benefit.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model
Within the scope of protecting.
