Abstract
The invention relates to an automatic sampler. The automatic sampler is characterized in that a support plate is provided with a cylinder; the input port of the cylinder is connected with a program control PLC (programmable logic controller) through a solenoid valve; the connecting rod of the cylinder is connected with the rotating shaft in a bunker; the rotating shaft is connected with a baffle plate; and the baffle plate is opposite to the material reception port of the bunker. Above design allows the online, timing, quantitative and continuous extraction of a plurality of detection samples to be extracted without influencing the production process of a main process, the uniformity and the representativeness of the extracted samples are good, and the operation is convenient and reliable.
Description
Technical field:
The invention belongs to the production of chemical fertilizer technical field, particularly a kind of self-actuated sampler that in industries such as chemical fertilizer, chemical industry, grain, mineral products, uses.
Background technology:
At present, a part of finished product often will be gathered or semi-manufacture analyzed from production line in process of production by production of chemical fertilizer enterprise, to be used to test chemical fertilizer product nutrient, constantly to adjust production technology and improving the quality of products.Mostly common sampling is to gather with artificial, for example uses sampling probe sampling, during sampling; Pipe in rotating earlier makes the mark screw be threaded to the right of outer tube groove, and trough cuts out, and is inserted into 1/2nd of bag with the sampling probe from the long-diagonal of packaging bag; Pipe is opened trough in rotating, pipe in sample gets into; Close trough then, extract the sampling probe again out, sample is poured in the sample sack.With the sampling probe, successively from four angles of every bag, press above-mentioned sampling mode collected specimens, every bag of taking-up is no less than the 200g sample, and the gross sample amount that the every batch of product is taked must not be less than 4kg.The artificial collection exists many defectives: 1, receive the influence of subjective factor, samples' representativeness and accuracy are relatively poor, fluctuation is bigger.2, the sampling frequency of hand sampling is less, ubiquity is poor, with actual bigger deviation is arranged.3, the manual process of hand sampling is loaded down with trivial details, and workload and labour intensity are bigger.4, hand sampling is loaded down with trivial details because of manual process, and the promptness and the accuracy of sampling are relatively poor.
Summary of the invention:
The object of the invention just is to overcome the deficiency that exists in the above-mentioned prior art; And a kind of self-actuated sampler is provided; It can be under the situation that does not influence main art production process a plurality of test sample of online continuous drawing at regular time and quantity; The sample homogeneity of being got is good, representative good, and easy to operate, reliable.
As above design; Technical scheme of the present invention is: a kind of self-actuated sampler; It is characterized in that: cylinder is installed on back up pad, and the input port of cylinder is connected through solenoid valve with programmed control PLC, and the connecting link of cylinder is connected with the interior rotating shaft of feed bin; Rotating shaft is connected with baffle plate, and the material receiving port of this baffle plate and feed bin is relative.
Above-mentioned solenoid valve adopts two-position-five-way solenoid valve.
The present invention has following advantage and good effect:
1, do not receive artificial factor, can increase substantially sample accuracy and representativeness.
2, the design's operation of coming opertaing device through the automatic sampling control program among the programmed control PLC; In whole sampling process; To confirm sample time, sampling frequency and sampling amount according to production quantity, kind; Realized automatic control fully, so greatly improved representativeness, promptness and the accuracy of sample collection appearance.
3, can be under the situation that does not influence main art production process, a plurality of test sample of online continuous drawing have at regular time and quantity improved the automaticity and the work efficiency of process.
4, reduce labour intensity, reduced artificial the input.
5, will start robotization and programmed control combines, make stable equipment operation, reliable.
6, applied range.The design can be in other industry promotion and implementation such as fertilizer industry and grain, chemical industry, mineral products.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a rear view of the present invention.
Fig. 3 is a side view of the present invention.
Embodiment:
As shown in the figure: a kind of self-actuated sampler; Cylinder 2 is installed on back up pad 1, and the input port of cylinder is connected through two-position-five-way solenoid valve 3 with programmed control PLC, and the connecting link 4 of cylinder is connected with the interior rotating shaft 5 of feed bin; Rotating shaft 5 is connected with baffle plate 6, and the material receiving port 7 of this baffle plate and feed bin is relative.Said procedure control PLC increases the control program of taking a sample automatically (design software and former PLC system node) in former Bulk Blending Fertilizer integral PLC.
This equipment is installed in the stirring machine afterbody in use.When beginning to take a sample; The instruction that two-position-five-way solenoid valve receives programmed control PLC begins to carry out switch motion; Gaseous tension in the cylinder is changed, and the cylinder connecting link drives rotating shaft, rotating shaft interlock baffle plate; The material receiving port of sample from feed bin is drawn into the discharging pipeline 8, and sample drops into to take a sample in the sample divider from the sample export on the discharging pipeline and finishes then.When needs stop to get material, make baffle plate capping feed bin material receiving port can stop to get material.
