Abstract
The utility model relates to a sampling valve of a filler bin of a mixing unit. The sampling valve is characterized in that an emptying valve is additionally arranged in the original pipeline of a storage bin of a mixing station, the other end of the valve is downwards bent so as to reduce the splashing of a sample caused by the pressure of a pipeline; and when being in use, the sampling valve is directly opened for sampling, and the valve is closed after the sampling is ended.
Description
Technical field:
This practical blending station filler bin sampling valve.This device is applicable to the material sampling of concrete mixing station filler bin.
Background technology:
Mixing concrete is tank car when standing in the concrete raw materials such as the cement of marching into the arena, flyash, slag powders and is transported to mixing plant, is inputed in the feed bin by pipeline.Find that at each engineering site blending station serious quality problems have appearred in the part material in recent years, suspect that by analysis manufacturer makes " interlayer " in tank car, admixture in flyash, the slag powders " stone flour " or other powders use the existing tube sampler can't be to the raw material uniform sampling in the tank car.
Summary of the invention:
In order to address the above problem, the utility model provides a kind of new powdered material sampling device, its features simple structure, easy operating, do not need other apparatus booster actions can finish the sampling process of whole test specimen, can extract at any time material in the powder course of conveying, and sampling is evenly representative.
Technical scheme: will increase dispensing valve in the original pipeline of mixing plant feed bin, be bent downwardly to reduce the sample that pipeline pressure causes at the other end one end of valve and spill, directly open valve during use and can begin sampling, valve-off after sampling finishes.
The beneficial effects of the utility model: can extract at any time material in the powder course of conveying, and sampling is evenly representative.Can prevent that the faulty concrete raw material from entering the job site, improve concrete raw material and concrete quality.
Description of drawings:
Fig. 1: be structural representation of the present utility model
The original feeding pipe of 1-feed bin among the figure; 2-conveying pipeline 3-metal valve; The 4-discharging opening;
The specific embodiment:
The constant head permeability apparatus: conveying pipeline and discharging opening adopt 1 cun (diameter 33.7mm) steel pipe, long 50mm, and the discharging opening total length is 200mm, the metal valve diameter matches with conveying pipeline and discharging opening.
One, by shown in Figure 1 with conveying pipeline, checks whether seepage of conveying pipeline (2) and the original feeding pipe of feed bin (2) weld.Metal valve (3) is connected 2 with conveying pipeline) connect, discharging opening (4) is connected to metal valve (3), and outlet is vertically downward.
Two, in sample when sampling, should carry out in the process that powder is carried to feed bin, and the container of splendid attire sample is placed discharging opening (4) below.
Three, open metal valve enters into the splendid attire sample by sample container.
Four, sampling is closed metal valve (3) after finishing.
Claims (1)
1. blending station filler bin sampling valve is characterized in that: will increase dispensing valve in the original pipeline of mixing plant feed bin, be bent downwardly to reduce pipeline pressure at the other end of valve, avoid the excessive sample that causes of pressure to spill.
