Description

This utility model relates to devices for storing agricultural products at low air temperatures.

A device is known for a thermal container for storing agricultural products (Description of the invention to the copyright certificate SU 1450784, A01F 25/14, published January 15, 1989, Bull. No. 2).

A thermal container for storing agricultural products, including a thermally insulated case with a lid, a perforated product container installed with a gap inside the case, an electric heater, a temperature control sensor with a control unit, and the electric heater and temperature control sensor are located on the casing in direct thermal contact with the latter, while The electric heater is located evenly on the surface.

The disadvantages of the known device are a large number of coolant elements necessary to maintain the required temperature in the usable volume.

Closest to the claimed utility model is a container for storing agricultural products (patent RU 2037998, A01F 25/14 (1995.01), published 06/27/1995) containing a thermally insulated housing with a lid, a power source, a temperature control sensor, a control unit and an electric heater connected with a control unit, and it is equipped with a removable bottom with ventilation holes.

The disadvantages of the known device are the complexity of the design with low performance in terms of operation of the thermal container.

The technical result of the utility model is a more uniform regulation of heat and moisture in a thermally insulated body of the thermal container, taking into account the natural factor of the material of the heater.

The technical result is achieved in the device, a thermal container for storing agricultural products, configured to be connected to a power source, comprising a thermally insulated body with a lid, a temperature and moisture control sensor, a heater, a perforated product container installed with a gap inside the body, a control unit, and a heater performed in the form of a massive matrix of calcined clay with a spiral shape of ribs, between which a heating cable is laid, the matrix is symmetrically located under the lower base of the perforated container for products which are proportional to the sizes of long and short sides of the matrix and the cross-section housing allow uniform air circulation upwards from the matrix on all sides of the perforated container products.

Distinctive features are:

- the heater is made in the form of a massive matrix of fired clay with a spiral shape of ribs, between which a heating cable is laid, such a manufacture of the heater gives more uniform regulation of heat and moisture in the heat-insulated body of the thermal container, taking into account the natural factor of the material of the heater;

- the matrix is symmetrically placed under the lower base of the perforated product container, which creates more uniform regulation of heat and moisture in the insulated case of the thermal container;

- proportional dimensions of the long and short sides of the matrix and the cross section of the casing are made, which make it possible to uniformly circulate air upward from the matrix from all sides of the perforated product container, this makes it possible to maintain the laminar air movement while regulating heat and moisture in the heat-insulated casing of the thermal container.

Comparison of the proposed solutions with analogues and prototype did not allow to identify in them the signs that distinguish the claimed solution, which allows us to conclude that the criterion of "novelty".

In FIG. 1 shows a diagram of the construction of a thermal container, in a vertical section along the axis of symmetry, containing a perforated container for products 5, a seat for a humidity and temperature controller with an electronic display 6, a massive matrix 7, a heating cable 8, a container for accumulating condensate 9, a cover plate 10.

In FIG. 2 shows a section AA from FIG. 1, containing the exhaust valve of the system of ventilation ducts 1, insulation 2, plastic housing 3, magnetic seal 4, annular spiral channel 11, electromagnetic shutter 12, inlet valve 13.

The manufacture and use of a thermal container for storing agricultural products is carried out in the following sequence.

The massive matrix is made using brick technology. Highly sticky clay is selected. A viscous mass is made from it, which is molded into a box with the inverse shape of the matrix. At the next stage, the matrix is pressed out of the box, dried in air and burned in a furnace. The cover plate of the heating cable is likewise manufactured.

A massive plastic matrix with a symmetrical arrangement under the lower base of the perforated product container is installed in the outer plastic shell of the thermal container body with the proportional dimensions of its long and short sides and the matrix; Then mount a plastic channel suitable for the massive matrix and around it in three spirals. Two plastic channels are installed under the condensate storage tank. Recesses are made and glued in them: side handles and a case for an electronic scoreboard. The free space between the outer plastic shell of the container and its inner shell is filled with foam insulation. Similarly, a prefabricated case cover is made and mounted on hinges. Installs: a magnetic seal, modeled on the tight fit of the refrigerator door, intake and exhaust valves, an electromagnetic damper, a heating cable, temperature and humidity sensors, an electronic display with all connecting wires and cables, trays for collecting condensate, a removable basket in the form of a perforated container for products.

The device is operated in the autumn-spring and winter periods with a range of adjustable: temperature on the device 0-20 ° C, humidity 0-98%. Overall dimensions 700 × 700 × 500 mm. The working volume of 70.5 liters. Power consumption 0.768-1.2 Sq / day.

The device is connected to the mains. Upon reaching the specified parameters, the perforated container 5 filled with agricultural products is installed in the thermal container. The minicomputer of the electronic scoreboard 6 regulates the natural flow of circulating air with the electromagnetic damper 12 according to the set parameters, which, passing through the annular spiral channel 11 around the massive matrix 7, heated by the self-regulating heating cable 8 used by the source [3], is directed past the cover plate 10 into the window with symmetrically located under the lower base of the perforated container for products 5 and a massive matrix 7 having proportional dimensions of the long and short sides of the matrix and the transverse with cheniya housing, creating the possibility of uniform air circulation upwards from the cover plate 10 on all sides of the matrix of the perforated container products 5 to the discharge valve ventilation system of channels 1.

Using the high heat capacity of the massive matrix of fired clay 7 with a spiral shape of the ribs, covered with a cover plate 10, the minicomputer of the electronic display periodically disconnects the heating cable 8 and turns it on after the consumed heat of the massive matrix 7. In case of emergency blackouts, the ventilation system works to dampen the temperature thermal container with a long period of time, much longer than that of the prototype.

Condensate is collected in two storage tanks 9 (the second one is not shown in FIG.) Formed from warm air upon contact with the colder surface of the inner shell of the housing and periodically changed to empty ones.

In autumn-spring thaws, a system is used, taken by analogy with dry ice. Use four removable cartridges of plastic bottled shells with a special liquid. Two of which are located in the freezer of the refrigerator, and the other two are installed in pull-out trays to collect condensate.

This manufacturing device makes a more uniform regulation of heat and moisture in a thermally insulated case, a thermal container for storing agricultural products, taking into account the natural factor of the material of the heater having an increased heat capacity.
