Abstract
The utility model relates to a building machinery for promoting pipe transportation of semi-fluid sand pulp by combining spiral propeller and secondary stirring system, called as spiral-propulsion-type sand pulp pipe transport system. The work principle of the utility model is that dry/damp material reaches a secondary stirring system (3) under propulsion of a spiral propeller (2); a high-pressure water feeding system (6) feeds water and fast stirs the material to semi-fluid sand pulp suitable for pipe transportation, and then the semi-fluid sand pulp is pressed into the transport pipe and transported to each work site. By combining the high propulsive force of the spiral propeller and the fluidity of the material after secondary stirring, the system can achieve long distance pipe transportation. The system has easy implementation, low cost, long transportation distance, continuous and pulse-free material transportation, and low transportation noise, and can conveniently achieve stepless speed adjustment and open up a novel way and a novel method for transporting sand pulp. The principle of the transport system can be applied to other fields needing spiral propeller and pipe transportation.
Description
Affiliated technical field
The utility model relates to a kind of building machinery, particularly a kind of spiral propeller and second stirring system is combined, and promotes the building machinery that the semifluid mortar carries out line transportation, is referred to as screw propulsion type mortar pipe-line transportation system.
Background technology
Builing industry carries semifluid material concrete, mortar etc. to adopt piston pump usually at present, this technology maturation, suitable material is extensive, conveying capacity is many, thrust is big, and fed distance is far away, but pulsation is strong, noise is high, power consumption is big, speed governing is difficult, therefore this technology is suitable for building the material pumping of class operation, and is unsuitable for outer powder, builds the operation that class needs the steady and continuous flow by laying bricks or stones.
Screw pump also can be used for carrying out material and carry.Screw pump be a kind of in the engagement rotary displacement pump, main working parts is eccentric metal screw rod (rotor) and the rubber bushing (stator) fixed, utilize between rotor and the stator cavity with medium continuously, average rate material is transported to output.This conveying technology substance, stickum such as oils etc. can solve preferably, but has great problem when carrying mortar.On the one hand it requires pulp consistency very little, otherwise in can't suction chamber, and its purposes of rare excessively mortar is limited greatly; On the other hand, the high abrasiveness of sand is fatal to rubber bushing in the mortar, even adopt the high abrasion composite material also to be difficult to solve, causes use cost high.Therefore this conveying technology fails to be used widely in builing industry always.
Extrusion pump is another material mode of movement, and the pump line that a composite material is made is housed in its pump case, on the rotating disk of pump squeezing roller is installed.During dial rotation, squeezing roller pushes pump line continuously, forces the flow direction of material conveying pipeline road in the pump line.After the extruding, the swabbing action of material during pump line has just formed hopper when restoring.Extrusion pump is suitable for that concentration is rarer, the pumping of no lost material such as mortar, and is not suitable for this semi-fluid height of mortar lost material, therefore can't be used to carry mortar.
Industry also has a kind of water jet pump, and the dry mix of preparing is by a certain percentage passed through the rotating disk segmentation, utilizes pressure-air to blow in rubber tube, mixes with water at jet hole to be sprayed by compressed air again, and high velocity jet is on scar or building surface.Material is interrupted in carrier pipe so that pressure-air promotes in the course of conveying.This mode of movement is mainly used in jet surface operations such as tunnel, bank protection, also is unsuitable for outer powder, builds the operation that class needs low speed, stable, continuous flow by laying bricks or stones.
Material is continuous when adopting spiral propeller (being commonly called as auger) transportation of substances, pulse free, and noise is little, and low-power consumption can stepless speed regulation, but spiral propeller only is suitable for the conveying of non-fluid substance such as powder, particle, sandy soil.Its operating principle is: be transferred in the passage that material falls under gravity into spiral propeller, the rotation of helical blade promotes it and moves forward.Because non-fluid substance is mobile poor, the inside of spiral propeller and end just form propulsive force and blocked force.If directly carry out non-fluid substance such as sand-lime and carry at the spiral propeller end pipeline that continues, along with pipeline prolongs, resistance will increase sharply.When spiral propeller thrust is equal with husky grey pipeline resistance, will quit work.
If directly carry the fluid mortar with spiral propeller, helical duct convection cell mortar is equal to a spiral pipe, and blade rotation can't form efficient pressure; If terminal pipeline has under the pressure condition, fluid also can produce backflow, therefore can't carry.If adopt the mode that improves revolution speed of screw to increase thrust, then wearing and tearing are inevitable increases greatly, and sharply shorten the application life of spiral propeller, and the big use cost of technical difficulty increases, and the purpose that increases productivity is difficult to realize.
In sum, provide a kind of can low speed, even, continuous, pulseless mortar induction system, to satisfy the outer powder of current builing industry, to build class mortar delivery requirements by laying bricks or stones and become the task of top priority.
