Description

The utility model relates to transport equipment and can be used for short-term storage and transportation of water, food liquids.

A known tank truck containing a chassis on which a container with several sections is installed, each of which has a filling and drain device, and the sections are made of shells, coaxially placed one in the other (I).

However, this design is complex and unreliable.

A known tank is a thermos for transporting liquid cargo with a temperature different from the ambient temperature, including a tank, multi-layer thermal insulation, a heater located between the tank and thermal insulation (II).

To ensure the transportation of liquids, a heater is needed to maintain the set temperature in the tank.

Closest to the claimed is a tank truck, including a chassis and a tank mounted on it with sections formed by transverse partitions, each of which

has drain and bulk devices. The latter are made in the form of pipe lines located inside sections of the tank and connected to a pump connected to the power take-off of the vehicle, and the output ends of the pipe lines with shut-off valves fixed to them are displayed in the control unit located in the rear end part of the tank (III).

The disadvantage of the tanker is its low operational reliability, especially when used in the cold season, at low ambient temperatures. At the same time, it is difficult to protect the tank with filling and discharge pipelines, bottom closures from destruction during freezing.

In addition, the presence of filling and discharge pipelines inside the sections of the tank not only reduces their useful volume, but also makes it difficult to inspect, rinse and disinfect the internal cavity of the sections, which leads to a decrease in the hygienic characteristics of the tank.

The objective of the utility model is to increase the operational reliability of the tank at a negative ambient temperature with high hygienic characteristics of the tank cavity.

The technical result consists in the fact that, in parallel with protecting the entire tank with a heat-insulating layer from freezing at a negative ambient temperature, in order to avoid freezing of liquid in the drain pipelines, the design of the tank truck provides:

1. heating the drain pipe of the first section with a liquid in the second section,

2. the execution of the drain pipe of the second section of the minimum length and with the protection of an additional thermal insulation layer.

In addition, the absence of pipelines in the first section makes its internal volume free and accessible for washing and disinfection, especially when it comes to food liquids, such as milk.

If there is a pipeline in the second section and its location in the very bottom of the section, it does not interfere with a sufficiently high-quality washing and disinfection of it together with the collector in an additional tank.

The technical result is achieved by the fact that in a tanker, mainly two-section, including a tank with first and second sections and a transverse partition between them, drain holes and drain pipes with shutoff valves in the service compartment, the drain hole is first

sections are made in the transverse partition, and its drain pipe is placed inside the second section in its bottom part and brought into the service compartment.

An additional tank is mounted under the second section of the tank on the side of the service compartment, which is equipped with a collector that communicates with the drain pipe and a drain hole in the tank shell in the form of two windows on both sides of the drain pipe of the first section, while the total window section is not less than the collector cross section.

The drain pipe is endowed with a minimum length and is also removed from the collector to the service compartment.

The capacity of the tanker is equipped with a heat-insulating layer, and its additional capacity is made with a double layer.

Signs that distinguish the proposed design of the tanker from the closest to it according to the prototype characterize the execution of the drain hole of the first section in the transverse partition, and the placement of its drain pipe in the bottom of the second section, thereby heating it with liquid in the section. In this case, the useful volume of the cavity of the first section is completely freed and the cavity of the second section is not cluttered.

An additional tank mounted under the second section with a collector and a heat-insulating double layer allows

not only perform the drain pipe of the second section of the minimum length, but also protect it from freezing and freezing of liquid in it at the outlet of the section.

The implementation of the drain hole in the casing of the tank of the second section in the form of two windows on both sides of the drain pipe of the first section allows the layers of liquid to be mixed intensively when draining, preventing a decrease in temperature in the area of the windows, as well as the drain pipe of both the first section and the drain pipe of the second section.

For optimal drainage of liquid from the drain hole of the second section, a total window cross section of at least a passage section of the collector is provided.

The utility model improves the operational reliability of a tank truck in conditions of negative ambient temperature and increases the hygienic characteristics of the tank cavity.

The analysis of scientific, technical and patent literature showed that the combination of all features of the utility model that are distinctive from the prototype meets the criterion of "novelty."

The drawing shows:

figure 1 - General view of the tanker;

figure 2 is a local increase in figure 1, in section;

figure 4 is a top view along arrow B in figure 3.

A tanker for transporting liquid, mainly two-section, includes a chassis 1 (Fig. 1) on which a container 2 of a single shell 3 (Fig. 2) is mounted, protected externally by a heat-insulating layer 4 and divided by a transverse partition 5 into sealed first 6 and second 7 sections.

A drain hole 8 is made in the transverse partition 5, a drain pipe 9 of the first section 6 is connected to it. A drain pipe 9 is placed in the bottom of the second section 7, discharged through the second section 7 into the service compartment 10 (Fig. 1) and is equipped with a locking device 17 ( figure 4).

Under the second section 7 (Fig. 3), an additional tank 11 is mounted on the side of the service compartment 10, in which a collector 12 is placed, which communicates with the drain hole of the second section 7 in the form of two windows 13 (Fig. 4) and a drain pipe 14 of the second section 7 ( figure 3). The windows 13 are made in the casing 3 (figure 2) of the container 2 (figure 1) and are located on both sides of the drain pipe 9 (figure 4) of the first section 6. The drain pipe 14 (figure 3) of the second section 7 is removed from the collector 12 in the compartment 10, has a minimum length and is equipped with a locking device 17 (figure 4).

Locking devices 17 drain pipelines with this design are provided in the form of a union nut and fitting,

by means of which, if necessary, a connection is made to the drain-fill sleeves or to the pumping unit.

The additional tank 11 (figure 3) is provided with a doubled thermal insulation layer 15 in comparison with the thermal insulation layer 4 of the entire tank 2.

The total cross-section of the windows 13 (Fig. 4) of the second section 7 (Fig. 3) is made not less than the passage section of the collector 12.

Each section 6 and 7 on top has a filler neck 16 (figure 1). On the neck 16 a top level sensor is installed (not shown in the drawing).

Tanker works as follows.

Before starting the operation of the tanker, it is necessary to sanitize the inner surface of sections 1 and 2.

Then, water or food fluid is pumped into sections 1 and 2 through the filler neck 16.

When filling the section of the tanker and triggering the upper level sensor located on the filler neck 16, the filling section stops. In the presence of a pump installation, filling can be carried out through drain pipelines 9 and 14. for this, the connecting sleeve from the pump is connected with a union nut to the fitting of the shut-off device 17 of the tank truck.

Draining the fluid can be done by gravity. In this case, the liquid through the drain hole 8 and the drain pipe 9 of the first section enters the tank outside the tank truck.

From the second section 7, the liquid first passes through the windows 13 into the collector 12 located under the section in the additional tank 11, and through the drain pipe 14 connected to it also into the tank allocated to it. In both cases, the liquid from the drain pipelines to the reservoirs allocated for them flows through the unloading hoses provided for in the tanker kit.

For the operation of the tanker at low ambient temperatures, it is equipped with a heat-insulating layer, in addition, the installation of the drain pipe 9 in the second section 7 allows it to be maintained heated by the liquid in the second section 7.

The design of the additional tank 11 allows the drain pipe 14 of the second section 7 to have a minimum length and with additional protection with an insulating layer to avoid freezing and possible destruction, which increases the operational reliability of the tanker.

The release of the useful volume of the first section 6 and the reasonable placement of the drain pipes 9 and 14 in the second section 7 can improve the hygienic characteristics of the tank.

The sections are drained and filled only from the end of the tank (there are no bottom drain holes), which simplifies maintenance of the tanker.
