Description

The sampler of easy-setting products from the tank refers to the equipment of storage facilities of the oil, oil refining and petrochemical industries and is intended for taking samples of light-setting products that require heating for carrying out technological operations.

The prior art devices for sampling (stationary samplers) for taking a point (unmixed) representative sample of a product from a certain level of the container in which this product is located (see, for example, GOST 2517-85 Petroleum and petroleum products. Sampling methods. M .: IPK Standards Publishing House, 2003. P. 14, Fig. 1 and 2), performed by introducing pipes into the reservoir whose open end ends at the level of a layer whose composition is interesting.

Since the known samplers have the same set of similar essential features for solving the problem by the claimed device, then any of them can be selected for the prototype of the claimed technical solution. For example, it is known a device for sampling liquid products from a reservoir, containing sampling tubes installed inside the reservoir, a sample drain valve, a pump connected to the collector inlet, an outlet to the drain cock (see RF Patent No. 566614 for utility model, IPC G01N 1 / 10, published September 10, 2006). In this device, the collector, vacuum pump, taps and tubes connecting them are located outside the tank. At temperatures that lie above the freezing point of the product stored in the tank, sampling takes place without problems. In practice, when operating at significant negative air temperatures, it is possible to clog the flow part of the nodes of such a sampling device located outside the reservoir with easy-setting products, by cooling the stationary products in the flow part during storage. This requires disassembling the device and cleaning it from plugs of the frozen product. In practice, to eliminate this, an additional supply of electric or thermal energy is used for the normal functioning of such a device, which leads to a rise in the cost of design and installation of the device.

The objective underlying the present utility model is to create a sampler of easy-setting products from the tank without bringing additional energy sources to the installation site of the sampler on the tank.

The technical result that can be obtained using the inventive utility model is to simplify and, as a result, reduce the cost of installation of the sampler, as well as increase the reliability during operation.

The task underlying the present utility model, with the achievement of the claimed technical result, is solved by the fact that a sampler of easy-setting products from the tank is proposed, consisting of a drain pipe and sampling pipes, a mixing tank, shut-off devices and a transfer pump. What is new is that the sampling tubes, mixer tank, shut-off devices, and transfer pump are grouped into a module and installed inside the tank, and the shut-off device and transfer pump drives, as well as the drain tube, are hermetically outward from the reservoir from which the sample is taken.

In addition, the sampling tubes, mixer tank, shut-off devices, and transfer pump are grouped in a module that is sealed from and located in the tank, and the free ends of the sampling tubes are hermetically removed from the module into the tank; the module is filled with liquid; the module is equipped with ribs to enhance heat transfer; the module is equipped with spikes for intensifying heat transfer.

The prior art does not reveal solutions that would have signs that match the distinguishing features of the inventive device for sampling liquid products from the tank, so the latter meets the condition of patentability “novelty”, and the possibility of using equipment for the production of oil, oil refining and petrochemical industries allows to conclude that it meets the condition of “industrial applicability”.

Preferred examples of the proposed technical solution are described below based on the drawings, where:

in FIG. 1 shows a general view of a sampler of easy-setting products from a tank;

in FIG. 2 shows a view A of an example embodiment of the sampler shown in FIG. 1 on the service side;

- in FIG. 3 is a sectional view B of an example sampler embodiment shown in FIG. 1 and FIG. 2;

- in FIG. 4 is a sectional side view of an example embodiment of a sampler with a sealed module;

- in FIG. 5 is a side view, cutaway, for example, of a sampler with a sealed module, washed by a product stored in the tank from all sides, the module being installed in the cap of large-sized product heating;

- in FIG. 6 shows a top view with a cut into the sampler with a sealed module located in a heated pipe outlet of the product from the tank.

These examples of samplers belong to several samplers of the same type, of the same purpose, providing the same technical result.

In graphic materials, the corresponding structural elements of the sampler of easy-setting products from the tank are indicated by the following positions:

1 - sampling tubes;

2 - locking devices;

3 - tank mixer;

4 - transfer pump;

5 - locking device;

6 - tube return product to the tank;

7 - drain pipe;

8 - drives;

9 - module wall;

10 - module;

11 - ribs;

12 - spikes;

13 - highly conductive fluid.

In FIG. 1 and FIG. 2 the wall of module 9 is conventionally not shown.

A sampler of easy-setting products from the tank is made as follows.

The free ends of the sampling tubes 1 are fixed at the levels from which sampling is necessary. Other ends are hermetically connected through shut-off devices 2 to a mixer tank 3, the inlet of which is connected to the outlet of the transfer pump 4. On the other hand, a shut-off device 5 is connected to the transfer pump 4 for pumping the product back to the tank or to drain the sample through which the transfer pump 4 can communicate with the product return pipe to the tank 6 or the drain pipe 7 and through it with a sample collector (not shown). Drain pipe 7, sampling tubes 1, mixing tank 3, shut-off devices 2 and 5 and transfer pump 4 are grouped into a module.

The actuators 8 of the locking devices 2, 5, as well as the transfer pump 4 and the drain pipe 7 are hermetically removed through the wall of the module 9 (Fig. 3). Optionally (Fig. 4), shut-off devices 2, 5, mixer tank 3, transfer pump 4 are grouped in module 10, hermetically isolated from the tank in which module 10 is located, and the free ends of sampling tubes 1 and product return pipe 6 are hermetically sealed withdrawn from module 10 to the tank. In this case, the actuators of the locking devices 2, 5, as well as the transfer pump 4 and the drain pipe 7 are hermetically removed through the wall of the module 9.

The wall of module 9 can be removable for easy access for servicing devices located in module 10. Module 10 can be equipped with ribs 11 or spikes 12 for intensifying heat transfer, which can be located both from the side of the tank and from the side of module 10.

It should be noted that the sampler assemblies grouped into the module can be located far enough from the walls inside the tank, for example, in caps of large-sized food preheating (Fig. 5) or they can be removed from the main volume of the product in the tank to the heated outlet pipe of the product from the tank during cold storage (Fig. 6).

Optionally, module 10 is filled with liquid 13 (Fig. 5), which must be low-freezing (and, in some cases, explosion-proof) and have a low viscosity at product storage temperatures to provide convective heat transfer, for example, selective transformer oil.

A sampler of easy-setting products from the tank works as follows.

A hot easy-setting product in the tank, heated by any known method (for example, by circulating external heaters, using sectional or steam-coil heaters installed inside the tank, and so on), freely washes samples collected in the module and installed inside the tank 1, the mixer 3, the transfer pump 4 and the locking device 2 (Fig. 3) or washes the sealed module 10 (Fig. 4). At the same time, due to the heat transfer of hot products to the wall and the thermal conductivity of the materials from which the walls of these sampler elements are made, heat is transferred to the product located inside these elements and it is in a state suitable for carrying out technological operations of pumping, sampling and draining the sample.

Before sampling, one or more shut-off devices 2 are opened (Fig. 1), the shut-off device 5 switches to the “open to pump product into the tank” position. The locking device 5 for draining the sample may have two positions: “open for pumping the product into the tank” and “open for draining the sample”. In the first case, when the transfer pump 4 is operated through the shut-off device 5, the product remaining after taking the previous sample passes through the product return pipe to the tank 6 into the tank. When the transfer pump 4 has been operating for some time, the product from taking the previous sample located in the flow channels of the sampler is replaced with an updated product coming from the tank levels corresponding to open shut-off devices 2. The shut-off device 5 is moved to the “open to drain the sample” position. The updated product enters through the sampling tubes 1 to the mixing tank 3 through the transfer pump 4 then through the shut-off device 5 to the drain pipe 7 and to the sample collector.

Thus, the utility model makes it possible to obtain a sample of light-hardening products from the tank without supplying additional energy sources to the installation site of the sampler on the tank.

The proposed technical solution is universal and can be applied in the construction of any types of reduced samplers, both multi-column and sectional, installed on tanks of various designs (underground, above-ground, and so on) with various light-hardening products - oils, fuel oils, cracking residues, resins and etc. The utility model is not limited to the sampler of FIG. 1-6 and may be repeatedly modified as part of the disclosure. All of the new features and combinations of features disclosed in the description and / or drawings are considered essential.
