Abstract

Bulk material sampler refers to devices for sampling bulk material and can be used in various industries. The objective of the utility model is the expansion of operational properties and increased reliability. The technical result that can be obtained by using the utility model is the possibility of using the sampler in any of its working positions, eliminating the possibility of pouring loose material from the sample after its selection. The task is achieved by the fact that the sampler of bulk materials contains a sampling vessel, a housing with a tip mounted with the possibility of movement and a handle. In this case, the sampling vessel is made in the form of a glass mounted in the device body in such a way that the perforating holes made on their lateral surfaces are opposite each other with the possibility of rotation by an angle φ / 2, where φ is the angle between the two nearest perforated holes, and the handle is connected to the housing through the cover with the possibility of opening and fixing. The use of the proposed sampler can improve the reliability of the selected sample of bulk material by combining the perforating holes of the body and the glass in a given place and at a given depth and sealing the sample at the place of its collection. It is easy to manufacture and operate and eliminates the spontaneous opening of a sampling vessel.

Description

The utility model relates to devices for sampling bulk material and can be used in various industries.

A device for sampling bulk material containing a rigid rod, at one end of which there is a tip, and on the other - a handle, an elastic chamber for sampling and installed with the possibility of reciprocating movement along the rod body (ed. St. USSR N 862034, C. G 01 N 1/20, 1979).

The disadvantages of the prototype should include the complexity of the design, manufacturing technology and insufficient reliability. In this design, when closing the slots in the corners of the convergence of the plates, the filling of bulk material occurs, which prevents the spring plates from completely closing without cleaning them.

The closest in technical essence and the achieved technical effect to the proposed technical solution is a device for sampling liquids from great depths from tanks or ponds (RF patent No.2018106 "Sampler of bulk materials" IPC G 01 N 1/20 from 08/15/1994).

It contains a rigid rod, on one end of which a handle is installed, and on the other - a tip. The housing is made with the possibility of reciprocating movement along the rod. A handle is installed on the body. The sleeve is rigidly connected to the tip, and between the sleeve and the housing there is an elastic chamber in the form of a cylindrical spring, the ends of which are respectively connected to the housing and the sleeve.

A sampler of bulk materials works as follows. To take a sample, it is immersed to the desired depth in the bulk material under investigation and the elastic chamber is stretched with the handle. Bulk material between the turns is poured inward, and after a predetermined period of time, the handle is released and the elastic chamber spontaneously contracts, closing the holes between the turns of the spring, filling stops. Then the sampler, filled with bulk material, is removed from it. Turning the sampler upside down, the sample taken is poured from the sampler into the container and sent for analysis.

The disadvantage of this device is that if you place the sampler in the process of sampling bulk material in a horizontal position, then it practically becomes inoperative, because bulk material flies through the elastic chamber, not lingering in it. In addition, part of the bulk material may remain between its turns, which does not allow the elastic chamber to completely spontaneously compress.

Therefore, this sampler may not be used for sampling all bulk materials.

The objective of the utility model is the expansion of operational properties and increased reliability.

The technical result that can be obtained by using the utility model is the possibility of using the sampler in any of its working positions, eliminating the possibility of pouring loose material from the sample after its selection.

The task is achieved by the fact that the sampler of bulk materials contains a sampling vessel, a housing with a tip mounted with the possibility of movement and a handle. In this case, the sampling vessel is made in the form of a glass mounted in the device body in such a way that the perforating holes made on their lateral surfaces are opposite each other with the possibility of rotation by an angle φ / 2, where φ is the angle between the two nearest perforated holes, and the handle is connected to the housing through the cover with the possibility of opening and fixing.

The essence of the utility model is illustrated by drawings, where in Fig.1 shows the position of the sampler of bulk materials in the initial state, in Fig.2 - during sampling and in Fig.3 - during the lifting of the sample,

where: 1 - a sampling vessel;

2 - case;

3 - cover;

4 - handle;

5 - perforating holes;

6 - conical tip;

7 - base;

8 - limiter.

The sampler of bulk materials consists of a sampling vessel 1 (figure 1, body 2 and cover 3 with a handle 4.

The sampling vessel 1 is intended for placement, storage and transportation of the sample. It is made in the form of a glass, on the side surface of which perforating holes 5 are made.

Case 2 is intended for placement and fastening on it of all parts of the sampler of bulk materials, as well as for its introduction into the environment with bulk material. It is a cylinder passing into a conical tip 6, the bottom of which is the base 7 for the sampling vessel 1. The base material 7

provides low friction when rotating the sampling vessel 1 relative to the housing 2. On the side surface of the housing there are perforating holes 5 located opposite the perforating holes of the sampling vessel 1 with the possibility of rotation through an angle φ / 2, where φ is the angle between the two nearest perforated holes.

The handle 4 is connected to the housing 2 through the cover 3 with the possibility of its opening and fixing on the housing. The cover 3 in the assembly process of the sampler is connected to the sampling vessel 1 by a threaded connection. On it, limiters 8 are installed with the inscriptions "Closed" and "Open".

In the initial state, the sampler of bulk materials is collected in accordance with figure 1. In this case, the handle 4 is set to the “Closed” position, which corresponds to the closure of the sampling vessel 1.

The device operates as follows (figure 2).

The sampler by pressing on the handle 4 is introduced into the bulk material. Moreover, his position may be arbitrary. After its full implementation, it is necessary to set the handle 4 to the "Open" position. In this case, the perforating holes 5 of the housing and the glass are located opposite each other, as a result of which the bulk material will enter the internal volume of the sampling vessel 1 (Fig. 2).

After sampling, it is necessary to set the handle 4 to the "Closed" position, which seals the sampling vessel 1 (figure 3). In turn, this contributes to the reliability of the selected sample. Then the sampler must be removed from the bulk material and deliver the sample for analysis.

In order to pour out the test material, you must first disconnect the cover 3 from the housing 2 and take out the sampling vessel 1 with the sample by the handle 4. Then it is necessary to unscrew the lid 3 from the sampling vessel 1. After which the sample is poured into the dishes for further analysis.

To take the next sample, the sampler is returned to its original state. If necessary, treat its inner surface.

The use of the proposed sampler allows to increase the reliability of the selected samples of bulk material by combining the perforating holes 5 of the body and the glass in a given place and at a given depth and sealing the sample at the place of its collection. It is simple to manufacture and operate and eliminates the spontaneous opening of a sampling vessel 1.
