 The purpose of the invention is the improvement of portability and other operational parameters.

 This is achieved by the fact that in the tank for cooling, storage and transportation of liquid products, including an external fence, consisting of an inner and outer wall, a foam layer, a support, a hatch with a shutter and a tube for supplying liquid, a heat exchanger with inlet and outlet pipelines, an agitator, the walls are made in the form of spheres, the outer of which is covered with a mirror film and provided with an elastic ring mounted in the diametrical plane with the possibility of changing position, and the heat exchanger is located outside on the inner surface of the wall, interconnected at the lower point of the sphere by tubular arcs, the upper ends of which are fixed on a horizontal tubular ring located along the edge of the hatch, divided by partitions into two halves, one of which is connected to the inlet pipe, and the other to the outlet, while the tube for supplying fluid to the tank is equipped with a sprinkler, in addition, the outer guard is mounted on the trolley with the possibility of articulated rotation, equipped with bearings, bearings and clamps th own position and capacity, and the supports are made with the possibility of changing their length.

 In addition, the upper surface of the trolley is concave and spherical, while the bearing bearings are equipped with a housing and racks that are mounted on the trolley with the possibility of rotation in the vertical plane and fixing them in the upper and lower position, and the latches of the outer fence are made in the form located on the upper and lower surfaces of the cart damping gaskets with suction cups, recesses and through channels filled with electrically conductive material, and the container supports are made in the form of hollow removable pipes c arranged in nests, which are made in the outer fence and equipped with pads, suction cups and shells with clamps.

 In this case, the bottom of the inner cavity is equipped with a tide-counterweight made of a material with high heat capacity, while the mixer is fixed motionless on the tide-counterweight.

 In addition, the fluid supply tube is perforated and provided with a stop, and the sprinkler is made in the form of a housing rotatably mounted on the perforated end of the supply tube, and tubes attached to it, the ends of which are bent in horizontal and vertical directions, while the outlet of the tubes is angled up to the top of the inner wall.

 In this case, the shutter of the hatch is made in the form of an elastic plug placed in the latter between the upper and lower disks, which are interconnected by screws and provided with mirror films, while a disk with a perforated edge along the edge is fixed on the upper disk using brackets.

 In addition, the foam layer is located between the walls, and the tubular arcs of the heat exchangers with the surface facing the outer wall are immersed in the foam.

 Distinctive features of the proposed technical solution, together with the known ones, provide a positive effect, which consists in increasing the transportability of the tank and improving its operational properties, that is, in reducing weight, specific metal consumption, increasing strength, reducing heat loss, in facilitating the handling of the tank, and washing it , loading and emptying, ensuring the stability of the liquid storage mode. This is achieved thanks to the proposed implementation of the external fencing, heat exchanger, trolley, supports, stirrers, shutter, liquid spray. Thanks to the proposed combination of features, the tank has the properties of a non-tilting sealed mobile thermos, which is at the same time a cooler (cooler), a stirrer, which are also equipped with automatic clamps on a soft pillow.

 Most fully the advantages of the proposed technical solution are given in the description of the device in statics and operation.

 In FIG. 1 shows a vertical section capacity; in FIG. 2 - bearing in the form of a bearing; in FIG. 3 is a kinematic diagram of rotation of the container on the bearings, bearings of the trolley, when the bearings are raised up and the bearings interact with the outer guard of the container; in FIG. 4 and 5 - diagram of the fixation of the tank and the cart, as well as the basic design of the damping gaskets; in FIG. 6 - layout of heat exchangers in the form of vertical tubular arcs, connecting them to a horizontal tubular ring, top view, partial section; in FIG. 7 - the same, vertical section; in FIG. 8 - the same, in axonometric projection; in FIG. 9 is a diagram of a sprayer, a partial longitudinal vertical section; in FIG. 10 - same, top view; in FIG. 11 - the curved end of the tubular element of the sprayer.

 The capacity consists of an external fence, which is made in the form of inner 1 and outer 2 walls, which are made in the form of spheres, and the space between which is filled with foam plastic 3, in order to reduce heat transfer and specific metal consumption (mass-to-useful volume ratio). In this case, the outer wall is covered with mirror film 4 (for example, from polyethylene, PVC with a mirror layer or foil). To ensure a decrease in the thickness of walls 1 and 2 and to prevent damage to them, as well as a mirror film 4, an elastic ring 5 is installed with the possibility of moving along a spherical surface on the latter outside in a diametrical plane.

 The tank is equipped with heat exchangers, which are made in the form of tubular vertical arcs 6, interconnected at the bottom of the sphere, and mounted on the inner wall 2 under the foam 3. The upper ends of these tubular arcs 6 are connected to a tubular ring 7, which is in communication with pipelines 8 and 9 for the supply and removal of refrigerant or coolant, equipped with valves 10 and 11.

 The tank is equipped with a hatch with a shutter, which, in order to simplify sealing and reduce heat transfer, is made in the form of an elastic stopper 12, located in the hatch between the lower 13 and upper 14 disks, which are interconnected by screws 15. Moreover, between the stopper 12 and the upper disk 14, as well as on the latter, mirror films 16 and 17 are fixed.

 The shutter is equipped with a tube 18 for supplying and discharging the stored fluid. The tube is equipped with a valve 19 and a pressure gauge 20. To ensure quick cooling of the liquid, the tube 18 is equipped with a sprayer 21 for spraying it on the inner wall.

 In order to ensure the possibility of reliable fastening of the containers on top of each other without additional fasteners, a disk 23 with a side 24 is mounted on the upper shutter disk 14 with brackets 22. In the latter, holes 25 are made for the release of precipitation.

 The tank is equipped with a mixer 26 and supports 27.

 To simplify operation, facilitate and fasten it on the site or in the vehicle, mixing the liquid, washing, etc. the container is mounted on a trolley 28, the upper surface of which is concave and spherical, and the lower is flat, and filter pads 29 and 30 are fixed on the upper and lower surfaces. The trolley 28 is equipped with bearings, which are made in the form of spherical bearings 31. The bearings 27 are made in the form of hollow tubular elements placed in sockets made in the outer enclosure of the tank with the possibility of longitudinal movement on the supports 27, on which damping punctures are fixed to move along their surface suction docks 32 and shells 33 with clips 34 in the form of screws. To increase the stability of the tank, as well as to slow down changes in the temperature of the liquid, to ensure its mixing at the bottom of the tank, tide 35 was made in the form of a body with a flat upper surface, and tide 35 is made of a material having high heat capacity and specific gravity (cast iron, ceramics, steel and etc.). The bearings-bearings 31 are placed in the housings 36 on the uprights 37, which are fixed with the help of the axles 38 in the brackets 39, equipped with clamps 40 and fixed on the carriage 28. In this case, the uprights 37 are mounted for rotation in the vertical plane and provided with head-stops 41 for the key 42 (Figs. 1-4). In this case, to simplify the mixing of the liquid and the washing of the container, the mixer 26 is made in the form of a rigidly fixed propeller screw (Figs. 1, 3, 7, and 8).

 To ensure automatic fixation of the container or trolley 28 on the site or in the vehicle in the elastic damping pads 29 and 30 are made indentations-suction cups. In addition, for automatic grounding of the tank in order to prevent the formation of a static electric charge, channels 45 and 46 are made in it in the gaskets 29 and 30, filled with electrically conductive material, for example, porous foam rubber, moistened with electrolyte, metallized rubber, etc. (Fig. 5).

 To ensure quick heating or cooling of the liquid and effective use of coolant by the coolant, the tubular ring 7, to which the vertical tubular arcs 6 and pipelines 8 and 9 with taps 10 and 11 are connected, is placed in the uppermost part of the outer enclosure, i.e. coaxial to the hatch, and is divided into two halves by two partitions 47 and 48 located between the inlet 8 and the outlet 9 pipelines (Fig. 6, 7 and 8).

 To accelerate the cooling or heating of the liquid supplied to the tank, the sprinkler 21 is made in the form of a housing 49 rotatably mounted on the tube 18 with sealing inner protrusions 50, mounted on the end stop 51 of the tube 18, the holes 51 extending into the body cavity being made in the latter. 49. On the housing 49 in a horizontal plane there are tubes 52 and 53, the ends of which are curved in the horizontal and vertical directions, i.e. directed at an angle to the horizontal plane with the exit towards the upper part of the inner wall 1 of the tank. The sprinkler 21 may be made of plastic, stainless steel, aluminum, etc. (Fig. 1, 9, 10 and 11).

 The device operates as follows.

 The empty tank is removed from the vehicle and mounted on the platform so that the trolley 28 rests on bearings 31. After that, the tank moves on the trolley 28 to a source of refrigerant or coolant (water or air, cooled or heated), which is supplied to the pipeline 8. Refrigerant or the coolant enters the first half of the tubular ring 7. Since the latter is separated by partitions 47 and 48, the refrigerant or coolant enters the vertical tubular arcs 6 and does not pass directly to the discharge pipe ode 9, and around the inner wall 1, cooling or heating it at the same time. The spent refrigerant or coolant is discharged through the pipeline 9 to its source (Fig. 1, 6, 7, 8).

 The stored liquid product (milk, water, drink, etc.) is supplied to the tube 18, which flows out of the tube 18 through an opening 51 therein, enters the cavity of the housing 49 of the sprayer 21 and is ejected from the tubes 52 and 53. Since the ends 54 are bent and directed to the side and up, then a reactive force is created, as a result, the housing 49 with tubes 52 and 53 rotate, and the liquid product is sprayed on the inner cold (or heated) wall 1, and this liquid product is sprayed onto the upper part of the inner wall 1, draining down last, it cools or on heats up (Fig. 1, 9, 10, 11).

 After filling, the container on the trolley 28 is moved to a storage location or vehicle, while the racks 37 with housings 36 and bearings 31 are rotated to a horizontal position (Fig. 4). As a result, the trolley 28 is lowered by the damping pad 30 onto the surface of the vehicle or platform. Since the gasket 30 is provided with suction cup recesses 44, it securely locks the trolley in a stationary position. In turn, the container is fixed in the same way on the trolley 28 using a spherical damping pad 29 with suction cup recesses 43. At the same time, the supports 27 are lowered, on which the shells 33 and the damping suction cups 32 are raised so that they are pressed against the mirror film capacities. In this position, the shells 33 and the gasket-suction cups 32 are fixed by latches 34.

 It should be noted that the outer fence in all cases is reliably grounded, which prevents the accumulation of electrostatic charge in it. This is ensured by the fact that the container is in contact with the metal trolley and the platform of the vehicle or storage through an electrically conductive material placed in the channels 45 and 46 of the gaskets 29 and 30 (Fig. 4, 5). Additionally, grounding passes through supports 27, because their upper ends touch the walls of the nests made in the outer fence (Fig. 4).

 During transportation, vibrations and shocks are well absorbed by the damping pads 29, 30 and suction cups 32. In this case, the shock-absorbing effect of the damping pads is enhanced by the presence of suction cup recesses 43 and 44, which simultaneously prevent the tank from spontaneously moving around the vehicle.

 The tide - the counterweight 35 improves the fixation of the container in an upright position, this is also facilitated by its installation on the spherical surface of the gasket 29.

 The presence of a damping elastic ring 5, moved along the surface of the mirror film 4, allows you to isolate the containers from one another, that is, to completely eliminate their damage even when the outer wall 2 is made of thin plastic.

 All of the above allows us to reduce the thickness of the walls 1 and 2, to reduce the mass of the tank without compromising its strength operational properties. Weight reduction makes handling capacity easier. The strength of the tank is increased due to the spherical shape of the outer fence, and also due to the fact that the tubular arcs 6 and the ring 7 form a rigid frame, which allows to reduce the wall thickness. The latter simultaneously contributes to faster cooling or heating of the liquid being poured.

 During transportation and storage, the liquid product is reliably insulated, which prevents a change in its temperature. This is facilitated by the presence of a foam layer 3, and mirror films 4, 16 and 17 on the outer fence and the shutter of the hatch, especially since the latter is made in the form of an elastic rubber stopper 12, which does not conduct heat well. In addition, the presence of the tide, a counterweight 35, which is a storage of heat or cold, also hinders the temperature of the liquid. The accumulation of heat or cold in it is accelerated due to the fact that all the tubular arcs 6 are connected to each other in the lower part of the sphere, forming a dense heat-exchange network under the tide, as a counterweight to 35. It should be noted that heat exchange with the environment is sharply reduced due to the fact that the tubular arcs are adjacent to the cooled surface on one side and are thermally insulated on the other.

 For transportation or storage of the tank can be installed one on top of another, for this, the trolley 28 of the tank to be installed is placed on the disk 23 with the side 24, which increases the reliability of fastening. Moreover, the presence of 24 holes 25 in the sides helps to displace air and improves the functioning of the suction cup recesses 44 of the lower gasket 30 of the trolley 28. In addition, the holes 25 prevent the accumulation of precipitation on the disk 23 and the formation of ice on it.

 Since the disk 23 is mounted on the brackets 22, it provides good access to the pressure gauge 20 and the valve 19 of the supply tube 18. The brackets 22 also prevent damage to the latter.

 Before emptying the container, a faucet opens to release vapors, the tube 18 is buried in the liquid. If it is possible to form a precipitate using a wrench 42 mounted on the abutment head 41, the strut 37 with the housing 36 and the bearing-bearing 31 is rotated upward on an axis 38 mounted in brackets 39 fixed on the carriage 28.

 In such an upper position of the strut 37 of all bearings 31 are fixed by clamps 40 (Fig. 2). In this case, the container is supported by bearings 31, and the trolley 28 is fixedly fixed by the suction cup recesses 44 of the lower gasket 30. After that, the supports 27 are buried in the seats and held in the raised position by the suction cups 32, as a result of the support, they turn into handles and caps of the capsizing device, with by which the rotation of the tank on the bearings 31 is ensured (Fig. 3). Since the mixer 26 is fixed motionless, it rotates together with the container, which ensures mixing of the liquid product. The container is washed in the same way. The indicated operations can also be carried out by shaking the container in vertical planes. Since the surface of the tide - the counterweight 35 is made flat, then the mixing of the liquid. The presence of the tide - the counterweight 35 prevents spontaneous tipping of the tank (Fig. 3). After this, it is possible to start pumping the liquid product through the tube 18, while the liquid enters through the sprayer 21, which partially rotates, which improves mixing of the product.

 To clean the container or drain the thickened product, the hatch opens, for which the screws 15 are loosened, the plug 12 tapers and is removed along with the disks 13 and 14, the tube 18 and the sprayer 21. Then the container rises above the gasket 29 of the trolley 28 using bearings 31. One or two supports 27 are removed. Based on the latter, the container easily tilts, and the product inside it is removed through an open hatch. This also eliminates the tipping of the tank down the hatch, since the weight of the tide - the counterweight tends to return the tank to the up position of the hatch. The capacity due to the presence of a hatch can be used to store sauerkraut, pickles, etc.

 Thus, in comparison with the prototype, the proposed capacity has the best operational properties, i.e. provides a more stable temperature regime of liquid storage, its quick cooling or heating; in addition, the tank is more convenient in loading, unloading, transportation, filling, cooling, washing, does not require special fasteners.
