The liquid accelerating agent supplying device comprises a liquid accelerating agent material barrel, a handcart and a screw rod type constant delivery pump, wherein a bracket is arranged above the handcart and the liquid accelerating agent material barrel is placed on the bracket; the screw rod type constant delivery pump is fixed on the handcart and located below the liquid accelerating agent material barrel; the screw rod type constant delivery pump is composed of a motor, a manual frequency converter arranged on the motor and a screw rod connected with the motor; the tail end of the screw rod is provided with a discharging opening and the middle part of the screw rod is provided with a feeding opening; the bottom of the liquid accelerating agent material barrel is provided with a feed delivery pipe and the other end of the feed delivery pipe is connected with the feeding opening; and the feed delivery pipe is provided with a control valve. The work principle is as follows: and a liquid accelerating agent flows out of the liquid accelerating agent material barrel and is conveyed into a high-pressure water pipe through the screw rod and the discharging opening under the condition that the pressure is provided by the motor, so as to finish the supply of the liquid accelerating agent.
Description
Technical field
The present invention relates to a kind of liquid accelerating admixture feedway.
Background technology
At present, sprayed mortar mode commonly used mainly contains two kinds, i.e. dry mixing method is sprayed and the wet-mixing method is sprayed.For a lot of different modes of being added with of accelerating admixture, the dry mixing method is sprayed most of powder accelerator that adopts, and directly mixes with aggregate in course of injection, and pumping or wind are delivered to the nozzle place then; The wet-mixing method is sprayed the then main liquid accelerating admixture that adds, and is delivered to the nozzle place separately by blast.The volume of accelerating admixture all has bigger influence for the performance of pneumatically placed concrete each side, therefore for the quality of its additive effect, is worth further research.
In dry mixing method sprayed mortar, mainly use powder accelerator.Its adding set has three kinds usually, is divided into threaded bore formula, thread plug formula and gear type by its structure, and these devices all are contained in the bottom surface that contains the accelerating admixture hopper.Powder accelerator often can not be blended in the aggregate uniformly, and is easy to be cemented in the top and the wall of drawing-in device, often blockage phenomenon.Moreover admixture powder accelerator springback capacity in construction is big, dust is many.The device that adds liquid accelerating admixture in the dry mixing method is few, mainly is that liquid accelerating admixture is directly added oral siphon, utilizes control valve to regulate addition, and is delivered to the nozzle place with compressed air as power.Such mode, make liquid accelerating admixture volume very inaccuracy, be prone to stop up, and can not guarantee that liquid accelerating admixture supplies with continuously uniformly, operation and transportation are all inconvenient.
Summary of the invention
To above-mentioned prior art; For overcoming the deficiency of above-mentioned prior art; The invention provides a kind of liquid accelerating admixture feedway; Be specially adapted to add liquid accelerating admixture in the dry shotcreting, it can control springback capacity and Dust Capacity effectively, mainly is applicable to the dry mixing method sprayed mortar in tunnel, side slope, the foundation ditch isolith geotechnique journey.
The present invention realizes through following technical scheme:
A kind of liquid accelerating admixture feedway comprises liquid accelerating admixture charging basket, trolley and screw constant displacement pump, and wherein, the trolley top is provided with the support that can hold liquid accelerating admixture charging basket, and liquid accelerating admixture charging basket is shelved on the support; The screw constant displacement pump is fixed on the trolley, is positioned at liquid accelerating admixture charging basket below, the screw constant displacement pump by motor, be located at the manual frequency modulator on the motor and the screw rod that is connected with motor is formed, the screw rod end is provided with discharging opening, is provided with charging aperture in the middle part of the screw rod; Liquid accelerating admixture charging basket bottom is provided with conveying pipeline, and the conveying pipeline other end is connected with charging aperture, and conveying pipeline is provided with the control valve that can control liquid accelerating admixture flow.
Said liquid accelerating admixture charging basket is marked with scale, can clearly see the reserves of liquid accelerating admixture; A conveying pipeline is drawn in its bottom, and is installed on control valve, to control the flow of liquid accelerating admixture, makes liquid accelerating admixture flow in the screw pump uniformly.Liquid accelerating admixture charging basket can be designed as uncovered, is furnished with bung, so that can repeat to add liquid accelerating admixture, in the construction, bung can prevent that accelerating admixture is contaminated.
Said trolley is a kind of running gear, is device conventional in the prior art, and it effectively is combined as a whole liquid accelerating admixture charging basket and screw constant displacement pump, and can promote walking, makes the supply of liquid accelerating admixture become an independent structures.
Said screw constant displacement pump is a kind of weigh feeder; Be device conventional in the prior art; It can accurately control the addition of liquid accelerating admixture: be divided into ten apertures altogether, 20 revolutions are arranged under ten apertures, the flow of revolution is fixed; Through regulating its revolution, can effectively control the addition of liquid accelerating admixture.
Liquid accelerating admixture feedway of the present invention during use, is connected discharging opening with high-pressure water pipe; Operating principle is: liquid accelerating admixture flows out from liquid accelerating admixture charging basket; Regulate its flow through control valve, get into the charging aperture of screw constant displacement pump, pumping pressure is provided by motor; Through screw rod, by the discharging opening force feed to high-pressure water pipe, thereby accomplish the supply of liquid accelerating admixture.
Liquid accelerating admixture feedway of the present invention has the following advantages:
1. this device makes liquid accelerating admixture be successfully applied in the dried spray technique, and the use of liquid accelerating admixture greatly reduces springback capacity and Dust Capacity, has improved working environment, has reduced construction cost.
2. the use of screw constant displacement pump, can effectively control the addition of liquid accelerating admixture: the addition of accelerating admixture all has bigger influence to the performance of sprayed mortar each side, as before final setting time, preceding later strength, adhesion strength, creeping property etc.
3. this device makes the interpolation of liquid accelerating admixture become an independently system, and can conveniently transport; Simultaneously, volume is little, does not take too many space.
