The sampler is interlocked with the conveyor transporting the fuel and operates in automatic mode. Ladle
Ticket 5

1.The use of coal in national economy. Influence of quality on the price of coal.

The huge needs of the country in fuel require a consistent increase in the rate of coal production and improvement of its quality.

Changes in the quality of mined coal with a simultaneous increase in consumer requirements necessitate intensive development and improvement of mechanical enrichment.

The “Fuel” element determines the cost of coal consumed for production and technical needs: for boiler houses, for heating and supplying hot water, forge forges in repair shops, at power plants, in ferrous and non-ferrous metallurgy.

With an increase in moisture, ash content of coal, its value decreases

When the ash content is exceeded by 1%. The cost is reduced by 1.5%,

With an increase in humidity by 1%. Cost reduced by 1.3%

Calorie content - heat output per 1 ton of coal (k.cal per kg)

2.Machines for the preparation of analytical and laboratory samples.

To process samples in the QCD, it is necessary to have the following machines: MPA, MPL-150, ... (laboratory sample cutting machine - pieces of coal up to 150 mm.), grinds coal to 0.3 mm, packed in jars of 500 g. sealed in accordance with GOST and sent to the laboratory.

In the laboratory, the sample is crushed to 0.2 mm using hammer or rod crushers.

This is a glass with a stem length of 25cm and a diameter of 30mm to 1cm.

The PA machine is a sample cutting machine for the preparation of analytical samples.

The initial material with a particle size of 0-10 mm, weighing 500-700 g is poured into the receiving hopper. From the hopper, the material flows by gravity to the vibrating feeder of the crusher, which evenly feeds it into the crusher.

The material is crushed to a particle size of 0.2 mm and enters the sample receiver through the slots of the ring. The sample is removed from the machine by removing the jar from the sample receptacle through the sample receptacle filter.

(It is forbidden: to start the sampler without guards or with damage to the guard, and also without guards)

Sampler briefing

Preparation of a sample act form (drafting a task)

The specialist of the testing laboratory (head of the testing laboratory, deputy head of the testing laboratory) draws up a direction (task) in the form of a sampling act (Appendix 1) to the responsible executor performing sampling (sampler).

The specialist issuing the assignment shall indicate in the sampling report:

Purpose of the study;

Name of the sample (sample);

Place of selection;

Determined indicators and, in accordance with this, the volume of each sample, taking into account the requirements of regulatory documentation (ND);

Types of samples taken (oral).

Before each task, the sampler receives information about the goals and objectives of sampling, about special conditions sampling. The route is agreed.

Briefing of samplers, including the methodology for performing sampling for microbiological studies; labor protection rules, safety regulations and rules traffic held once/semester.

Having received the task, the sampler completes the necessary set of dishes (number of containers, their volume, samplers). Places it in a special refrigerated container made of durable plastic with a lid (to prevent secondary contamination of samples during transportation and damage to containers), after placing a napkin soaked in a disinfectant solution on the bottom

After receiving the task, the sampler, after agreeing on the route, is delivered by company vehicles to the places (points) of sampling.

For sampling water for microbiological analysis, only sterile containers are used. When sampling at the same point for different purposes, samples for bacteriological examination are taken first. Water after disinfection with chemical reagents is taken into a container with a dechlorinator (sodium thiosulfate).

The volume of water sampled depends on which microorganisms are to be determined. When analyzing water for indicator microorganisms - at least 500 ml. When analyzing water for indicator and pathogenic bacteria (salmonella) - 1.5 l.

Surface samples are taken from a depth of 10-15 cm from the water surface or from the lower edge of the ice. Bottom samples are taken 30-50 cm from the bottom. Sampling should be carried out using various watercraft, from bridges, scaffolds, etc., in places where the depth of water bodies is not less than 0.5 m. It is unacceptable to take samples from the shore.

The container is opened immediately before sampling, removing the stopper along with a sterile cap. During sampling, the cork and the edges of the container should not touch anything. Do not rinse dishes! When filling containers, there must be a space between the cork and the surface of the water. , so that the cork is not wetted during transportation. After filling, the container is closed with a sterile stopper and cap.

The selected sample is marked - it is assigned a number, which is applied with a marker on the glass. This number is affixed by the sampler opposite the record of this point when filling sampling act . Sample containers are placed in a refrigerated container, at the bottom of which there is a napkin with a disinfectant solution.
