Abstract

The utility model relates to a concrete gravity transportation of the civil construction engineering, in particular to a hose pipe transportation of the slope high fall and low slump concrete of high mountains and steep gorge areas from the high place to the low place. The utility model is composed of an inlet variable intercept area, an upper extrusion energy cutting area, an upper material mixing area, a lower extrusion energy cutting area and a lower material mixing area. When in transportation of the concrete by the hose pipe, the concrete is arranged on the hose pipe with certain spacing intervals, the speed of the concrete which is falling in the high speed is decreased, then the concrete which is ready to have the isolation and the separation can be fully stirred and mixed again. The anti-separation hose pipe has simple structure, short installation period and low cost, when in downward transportation of the concrete with the big fall, the utility model can prevent the isolation and separation of the concrete and ensure the quality requirements of the concrete after the transportation.

Description

A kind of be used to preventing that concrete from sending the anti-splitter of emanating because high drop slips

Technical field

The utility model relates to the concrete gravity transportation of civil works, relates in particular to the elephant trunk transportation from high to low of the high drop low slump concrete in high mountain gorge abrupt slope, area.

Background technology

In known technology, concrete slips facility such as sending existing MYBOX, negative pressure of vacuum chute from high to low in application, but the MYBOX structure is complicated, and processing is difficulty; The negative pressure of vacuum chute, the influence that is subjected to the abrupt slope angle is restricted on using.

Summary of the invention

The purpose of this utility model is intended to overcome the deficiencies in the prior art and provides a kind of and be used to prevent that concrete from sending the anti-eliminator of emanating because of high drop slips.

The utility model is achieved in that a kind of be used to preventing that concrete from sending the anti-splitter of emanating because high drop slips, it is characterized in that it from top to bottom by import become to cut district 1, upper extruding cut can distinguish 2, upper mixed material area 4, lower extruding cut can distinguish 6, lower mixed material area forms 5, that import become to cut is young in the district 1, end opening is big, and the top elephant trunk is connected with the anti-splitter main body; Upper extruding cut can distinguish 2 and lower extruding cut and can distinguish 6 and be pipe, suitable for reading is that circle, end opening are oblate, the anti-separating plate 3 of built-in ellipse and 7, the base that can distinguish 6 interior anti-separating plates 7 and upper extruding are cut in lower extruding, and to cut the base that can distinguish 2 interior anti-separating plates 3 mutually vertical, upper mixed material area 4 is pipe, and lower mixed material area 5 is upper big, lower little reducer pipe.

---the angle of described

anti-separating plate

3,7 and pipe oblique is 5 °～45 °.

Operation principle of the present utility model is: concrete mixes in upper and lower mixed material area, and lower mixed material area is connected the anti-splitter main body with the bottom elephant trunk.Concrete enters upper extruding through the import change section district of anti-splitter and cuts and can distinguish, and after bumping against with anti-separating plate, falling speed reduces, and falling direction is inwardly turned back, and concrete pushes mutually, enters the interior mutual collisional mixing of mixed material area, reaches for the first time batch mixing mix effect.The concrete of batch mixing mix enters lower extruding and cuts and can distinguish through the first time, bumps against with anti-separating plate, and speed further reduces, direction inwardly turn back (direction of turning back and upper extruding cut to distinguish vertical), concrete pushes mutually, enters mutual collisional mixing in the lower mixed material area, carries out the batch mixing mix second time.Can not export anti-eliminator discretely through the concrete of twice batch mixing mix and enter bottom elephant trunk or feeding equipment.When high drop abrupt slope elephant trunk transportation concrete, anti-splitter is installed on elephant trunk at a certain distance just can effectively prevents concrete segregation or separation, guarantee to meet the demands through the concrete quality of elephant trunk transportation.

The beneficial effects of the utility model are: low to the engineering-environment conditional request, installation workload is little; Travelling speed is fast, efficient is high; Easy and simple to handle, security of operation; Need not electric fixtures, energy-saving and cost-reducing, cost is low.

Anti-eliminator of the present utility model uses round steel pipe and steel plate to make, but electric welding welding, bolt connect.
