Abstract

The utility model relates to a powdery material sampler. The utility model is composed of a cam, a sampling head, a sampling connection tube, a sampling valve, an outer case of the sampler, sliding bearings, a spring, a flange, a material discharging tube and a sliding rod of the sampling head. The cam 1 is installed on a shaft of a screw conveyor, the sampling tube extends into a corresponding position of the conveyor, one section of a blade of the conveyor is cut off to install the sampling connection tube, the sampling valve in the outer case of the sampler and the flange are fixedly installed on the sliding rod of sampling head, two sliding bearings are installed on the outer case of the sampler, and the sliding rod of the sampler can slide in the two sliding bearings.

Description

The granular material sampler

The utility model relates to the cement industry chemical examination, and the sampling technique field of test analysis is used for chemical analysis, the sampling work of various granular materials in the instrument test.

The sampling of cement mill granular material at present, many employing hand samplings, belong to the batch (-type) sampling, sample representation is bad, and when sampling destroyed sealing, the dust from flying of conveyor, contaminated environment, also easily produce personal injury, the inequality of sampling, the impact analysis result just influences production technology and product quality.

Task of the present utility model is exactly at the weak point of above-mentioned existing sampling method and design and installation can be continuous on worm conveyor, uniform sampling, sampling amount can regulate continuously through compound granular material sampler.Can overcome the sampling inequality of existing sampling technique, representative bad shortcoming.

Content of the present utility model can be referring to shown in the Figure of description 1-2.

The utility model mainly contains cam 1, sampling head 2, and sampling head slide bar 14, sampling takes over 3, sample cock 4, sampler shell 5, sliding bearing 6, bead 9, spring 8, discharge nozzle 10 constitutes; Cam 1 is installed on the axle of worm conveyor, rotate with the worm conveyor blade, sampling is taken over 3 and is passed screw conveyor housing, and weld with the conveyor shell, take over 3 relevant positions that put in sampling conveyor blade is cut one section, do not hinder sampling head 2 to be as the criterion when rotating with it, sample cock 4 and bead 9 are fixedly mounted on the sampling head slide bar 14 in the sampler shell 5, spring 8 is being enclosed within after the bead 9 on the sampling head slide bar 14, two sliding bearings 6 fixedly mount outside on the sample device shell, and sampling head slide bar 14 can slide in two sliding bearings 6.Adjust the thickness of pad 7, the amount of scalable sampling.

The mounting means of cam 1, under the certain situation of worm conveyor specification, it is suitable the handle of cam 1 can be stretched out size adjustment, weld on the axle of worm conveyor, also can be as shown in Figure 1 fixing with crown nut 15, extension elongation that can the adjustment cam handle when needing be to regulate the amount of sampling.

During use, elder generation's adjustment cam 1, when it was rotated with worm conveyor, the moving all samplings by impaction of revolution 2 once progressively were pressed into sampling with sampling head 2 and take over 3, the medial surface of sampling head 2 is brought material into sampling and is taken over 3 simultaneously, in sampling head 2 was pressed into, sample cock 4 was opened, and bead 9 makes spring 8 compressed energy-storages, material is taken over 3 through sampling and is flowed out from discharge nozzle, enters the charge cup.When cam 1 left sampling head 2, sampling head 2 was under the effect of spring 8, and the resistance that overcomes material ejects sampling head 2 come from sampling adapter 3, sets back, and the to-and-fro movement that goes round and begins again is so constantly taken out material successively.

Advantage of the present utility model is as follows:

This apparatus structure is simple, handling ease, and cost is low, and is easy for installation, and sampling is continuously, representative, the rapping effect is arranged, be difficult for stopping up the reliability height, make analysis result more accurate, energy stabilizing cement production technology improves cement quality, is particularly suitable for Small and Middle Scale Cement Plants and promotes the use of.
