Continuous type mixing station stock bin with online sampling device and sampling method

Abstract

The invention discloses a continuous type mixing station stock bin with an online sampling device and a sampling method. The continuous type mixing station stock bin comprises a conveyor belt rack, ahanging beam, a guide hopper, a guide tube and a finished product bin, wherein the conveyor belt rack is placed in an inclined mode; the hanging beam is in bolt connection to the conveyor belt rack; the guide hopper is hinged with the hanging beam; a blocking plate is welded on the guide hopper; the lower part of the guide hopper is equipped with the finished product bin; one side of the finishedproduct bin is hinged with the guide tube; and the discharge end of the guide tube is connected to the conveyor belt rack through a weighing scale. The sampling method comprises the following steps: I, clearing zero for a weighing sensor; II, inputting a sampling weight value, namely a preset value; III, automatically sampling by pressing down an enter key, and controlling a pulling hopper gas cylinder to push back the guide hopper while accumulated flow achieves the preset value, thereby accomplishing sampling. The continuous type mixing station stock bin is simple in structure, is convenientand quick in sampling, and can realize online automatic sampling.

Description

technical field [0001] The invention belongs to the field of road construction, and in particular relates to a continuous mixing station silo equipped with an online sampling device and a sampling method. Background technique [0002] In my country's road construction projects, some mixtures are produced using continuous mixing equipment. In order to test the various indicators of the mixture, it is necessary to sample the mixture regularly or irregularly. Because sampling is very difficult in the production process of continuous mixing plants, the current main sampling methods are manual sampling on the transport vehicle or shutting down the mixing equipment and manually intercepting a certain length of mixture on the conveyor belt. The former method of sampling is not only time-consuming and laborious, but also has potential safety hazards, and the mixture after loading has material segregation phenomenon, which makes it difficult to obtain representative samples; in the l...

AI Technical Summary

Problems solved by technology

The former method of sampling is not only time-consuming and laborious, but also has potential safety hazards, and the mixture after loading has material segregation phenomenon, which makes it difficult to obtain representative samples; in the latter sampling method, the equipment must be shut down, which will affect the quality of the mixture. Continuous production, and online sampling cannot be realized
