Description

The technical solution presented in this description relates mainly to one of the main components of devices or machines for applying anti-icing reagent to the road, in particular to tanks, tanks, vessels, tanks or closed bunkers of such machines and devices, while the design features of the tanks are that in the process of their use in work, the excess pressure changes from the reactions of the chemical component in the tank when it is mixed with a liquid component, such as water. In this case, a significant amount of heat is released, which, together with excess pressure, has a negative effect on the walls of the tank. Moreover, the tank is in motion on the vehicle and its walls are also negatively affected by alternating loads from acceleration and deceleration of the vehicle and from movements in the tank in different directions of the liquid reagent.

The tank is intended primarily for the delivery of anti-icing reagent components by vehicle, the manufacture of the reagent by mixing the reagent components in the tank during its delivery to the place of use of the reagent. The tank is essentially one of the nodes of the design of the machine for applying anti-icing reagent on the road surface, while on the specified machine there are several tanks located in parallel, identical in design, each of which is connected to the adjacent tank and the vehicle of the machine. This tank can also be used to deliver chemicals with heat dissipation properties.

Thus, the technical solution, in accordance with the international classification of inventions, relates mainly to reservoirs for carrying out chemical and physical processes in them in the presence of water using jet mixers located in the tanks, including circulation mixers. In another direction, the technical solution also relates to closed containers made of plastics for storage and transportation of chemicals.

The technical solution is intended primarily for its use in the construction of devices for preventing slippage on roads in which tanks for liquid reagents are used, and more particularly, to devices for applying and distributing liquid reagents having tanks for reagents with mixers located in them.

A device for preparing anti-icing reagent in the tank, which contains the lower, side and upper walls, a hole for the exit of the reagent and the neck for loading the tank with the components of the reagent (RU 2123082, 1998-12-10).

Also known are machines for distributing a liquid reagent on a road surface from tanks installed on a delivery vehicle, each tank having a lower, side and upper wall, a hole for reagent outlet in the lower wall, and a neck for loading the tank with reagent components in the upper wall.

11 is a diagram of a tank with mixer ejectors located therein, explaining the operation of the tank;

in Fig.12 is a schematic diagram of the mutual arrangement of the recesses of the walls and the ejector in a plan view.

The tank contains side walls 1-4 (FIGS. 1, 3), a lower wall 5 and an upper wall 6, while at least one opening 7 is made in the lower wall for a means for mixing reagent components, for example, an ejector or pipeline ( not shown) for supplying a liquid component to the tank under pressure. In the upper wall are made necks 8, hermetically sealed with covers 9.

In the side walls 1-4 and the upper wall 6, a plurality of recesses directed inside the tank are made, which form stiffening ribs 10. Each rib 10 (except for the ribs of the upper wall) is perpendicular to the bottom wall 5 of the tank (to its bottom). From the inside, the recesses of the stiffening ribs 10 form a ribbed surface on all walls of the tank, except for the lower wall (Fig. 12).

The height of the tank is divided into the upper part 11 (1, 10) and the lower part 12 with two protruding outward supporting elements 13 in the form of bulges located on two opposite side walls 3 and 4 of the tank. The supporting elements 13 are used to support the tank on a special cassette (not shown), in which several tanks are installed and fixed (figure 10). The width of the upper part 11 of the tank is less than the width of its lower part 12.

The tank is also divided into two indicated parts by two ledges 14 (Fig. 4), which are located on two other opposite side walls 1 and 2. The ledges 14 serve to interact and connect adjacent tanks to each other. The tanks connected to the tank block (figure 10) are adjacent to each other with their lower parts 12, while there are gaps between the upper parts 11 of the adjacent tanks.

The upper part 11 of the tank is made with two opposite edges 15 narrowed upwards (Fig. 1) and tides 16 on these faces. In the inner circuit of each tide 16 there is a neck 8 with a cover 9 (Fig.2, 9).

In each supporting element 13, a hole 17 is made (FIGS. 2, 4) vertically oriented with respect to the bottom wall 5 of the tank. The hole 17 is made under the fastening element (not shown) of the tank to the tank delivery means and to the place of use of the reagent located in the tank.

Parts 11 and 12 of the tank can be separable along the line of their connector, while such parts are hermetically connected along the perimeter of their connector with fasteners 18 (Fig. 1).

The tank is made of heat-resistant durable plastic with heat-insulating properties. All angles 19 of the tank are rounded.

The drawings conventionally show the means 20 (Fig. 10) for delivery of tanks, the axis 21 of the movement of the means of delivery 20, the elements 22 connecting the tanks to each other, a solid granular component 23 (Fig. 11) and a liquid component 24 (water) located in the tank time of their delivery to the place of use.

To explain the operation of the tank, FIGS. 11 and 12 show a pressure pipe 25 which is communicated through an opening 7 in the bottom wall 5 of the tank with its working cavity. A high pressure pump (not shown) is connected via a pressure line to mixer ejectors 26 located inside the tank. Position 27 shows the jet of the liquid component exiting the ejector 26. The recesses 28 of the ribs 10 stiffness are located in the cavity of the tank. The recesses 28 are elements of stiffeners. The recesses in the cross section may have a different shape, preferably rounded or, for example, in the form of a trapezoid, as shown in Fig. 12.

The tank works as follows. The tank is fixed on the means 20 (figure 10) for the delivery of reagent components so that its walls 1 and 2 (figure 10) are located across the axis 21 of the movement of the means 20 of the delivery. Then, tank connection elements are inserted into the openings 19 of the support elements 13 and, using the straps 22 and connection elements, the tanks are rigidly connected to each other and to a special cassette (not shown) fixed to the delivery vehicle. Then the fastening elements are introduced into the openings 17 of the steps 14 and the tanks are additionally fastened by them to the cartridge, which is then rigidly connected to the tank delivery means 20. As a result, all the tanks are connected rigidly between themselves and the delivery means 20 in the position shown in FIG. 10.

Solid granular component 23 and liquid component 24 (for example, water) are loaded into each tank through the mouths 8 (Fig. 9), the tank necks are sealed with caps 9 (Fig. 10), and the components are delivered to the place of their delivery and use.

When moving the delivery means 20 and the tanks, the liquid component 24 is applied under high pressure to the granules of the solid component 23 in each tank and the components are bubbled through the liquid component into the tank through the pressure pipe 25 and mixer ejectors 26. As a result, the solid component dissolves in the liquid component, and heat dissolves when dissolved. The pressure in the tank rises from heat and from the liquid component entering the tank under pressure.

During the operation of the ejectors 26, the granules of the solid component are carried away by the jets 27 of the liquid component and at high speed hit the recesses 28 of the stiffening ribs 10 protruding into the tank, change direction and intensify the bubbling mode of mixing of the reagent components.

Simultaneously, from the movement of the delivery vehicle, acceleration and deceleration forces are transmitted to the liquid component located in each tank, and the granules of the solid component move together with the liquid component in different directions. This provides additional mixing of the granules of the solid component with the liquid component, accelerates and improves the dissolution of the solid component and contributes to the quality of preparation of the reagent. The described process for the preparation of the reagent takes place in hermetically sealed tanks.

During the delivery of components and their mixing, excess pressure is created in the tank and forces arise on its walls, which are perceived by the walls of the tank and their stiffeners, which provide sufficient stability of the tank under the influence of excessive pressure and heat loads on its material, which tend to soften the material of the tank, dynamic loads from accelerations and decelerations of the delivery vehicle, as well as mechanical loads on the tank walls. Due to the fact that the tank walls are made of heat-resistant plastic with a large margin of resistance to thermal loads in the range from -50 to + 70 ° C, the presented tank provides high reliability and safety of the delivery of a hazardous (at a certain concentration) chemical reagent. In this case, an effective and safe preparation of the reagent is achieved during the delivery of its components to the place of use.
