Abstract

The present invention relates to a heating chamber structure of an agricultural warmer for supplying a warm air of a certain temperature to vegetables and flowers grown in a plastic house or glass greenhouse.

A conventional hot air fan is configured to supply hot air by heating a high temperature combustion gas combusted in a combustion chamber through a combustion gas pipe communicating with a combustion chamber and passing outside thereof, and the air supplied from the outside is supplied to the air inside the heating chamber. Since there is no blocking block to block the flow, it passes through the outside space of the high temperature combustion gas pipe for a short time, and the heat efficiency decreases, and the fuel consumed to raise the supplied air to an appropriate temperature has an excessive disadvantage.

In the heating chamber of the hot air blower according to the present invention, in order to solve the above-mentioned drawbacks, the half-moon-type blocking plate is alternately installed in the heating chamber at right angles to the combustion gas pipe, and the air is supplied by the blower. It is a heating chamber structure of an agricultural hot air heater, which has been stagnant and warmed up from a hot combustion gas pipe for a sufficient time, thereby improving thermal efficiency and reducing fuel.

Description

Structure of heating for farming fan

The present invention relates to a heating chamber structure of an agricultural hot air fan that supplies a constant air temperature to a limited space such as a vinyl house, and more particularly, a plurality of combustion gas pipes vertically from the combustion chamber to the combustion gas collection chamber. To increase the area where the heated air contacts, and repeatedly install the half-moon blocking plate at right angles to the combustion gas pipe inside the heating chamber to stave off the progress of the heated air. The present invention relates to a heating chamber structure of an agricultural hot air fan, which is configured to increase heating efficiency by lengthening the time for supplying heat from a hot combustion gas pipe.

The inventor of the present invention has applied for a heating chamber structure (utility model registration application No. 2001-5597) of an agricultural hot air fan using a ring-shaped membrane plate and a circular membrane plate, but it has a disadvantage in that the production is complicated and the thermal efficiency is low.

The present invention was developed in view of the above-described conventional problems, and an object of the present invention is to reduce the consumption of fuel by increasing the thermal efficiency of a hot air blower, and also to reduce the heating cost due to the reduction of the fuel used and the cost of the produced product. Its purpose is.

The object of the present invention is to cut a portion of the circular plate to form a half-moon blocking plate, and the half-moon blocking plate is drilled through a plurality of combustion gas pipe through-holes and installed in an orthogonal direction to the combustion gas pipe to prevent it from being repeatedly installed. It is achieved by the heating chamber structure of the agricultural heating fan characterized in that.

As shown in Figure 1 to 2,

The present invention provides a fuel supply pipe 11 through which fuel is supplied from the outside of the cylindrical heating chamber 1 through the fuel pump 12, and a combustion gas outlet 5 through which the supplied fuel is combusted to discharge the combustion gas 10a. ), An air supply pipe 7 through which air is supplied from the outside to the inside of the heating chamber 1 by the blower 6, and a hot air discharge port 9 through which the hot air 10 is discharged to the vinyl house and the glass greenhouse. The combustion chamber 2 which burns fuel, such as petroleum, is comprised in the lower part of the inside of the heating chamber 1, and the combustion gas 10a is discharged in the upper part of the inside of the heating chamber 1 before exhausting the combustion gas 10a to the outside. The combustion gas collection chamber 4 is collected.

The high temperature combustion gas 10a generated by burning fuel such as petroleum is collected in the combustion gas collection chamber 4 through a plurality of combustion gas pipes 3 connected vertically from the combustion chamber 2 and then discharged to the outside.

FIG. 3 is a perspective view of a half-moon blocking plate 8 mounted alternately with the combustion gas pipe 3 inside the heating chamber 1 at right angles.

The half-moon blocking plate 8 formed by cutting a part of the circular plate is formed in the same size as the inner circumferential surface of the case of the heating chamber 1 so that the outer circumferential surface of the half-moon blocking plate 8 is In close contact with the inner surface, a plurality of combustion gas pipe through holes 8a are formed in the half-moon blocking plate 8 so that the combustion gas pipe 3 passes through the combustion gas pipe through-hole 8b of the half-moon blocking plate 8. And penetrating through the half-moon blocking plates 8 to the combustion gas collection chamber 4.

Such a half moon blocking plate 8 is repeatedly installed in the heating chamber 1 alternately with the combustion gas pipe at a right angle.

The heating chamber 1 of the agricultural warmer according to the present invention by the configuration as described above operates as follows.

Fuel such as petroleum is supplied to the combustion chamber 2 through the fuel supply pipe 11 by the fuel pump 12, and the fuel is burned in the combustion chamber 2 to generate a high temperature combustion gas 10a. The gas 10a moves from the combustion chamber 2 to the combustion gas collection chamber 4 through the plurality of combustion gas pipes 3, moves to the combustion gas collection chamber 4, and is discharged into the atmosphere.

The outside air supplied into the heating chamber 1 by the blower 6 receives the heat transfer from the high temperature combustion gas pipe 3 to become the warm air 10, which is installed in a direction perpendicular to the combustion gas pipe 3. The cutting portions 8b of the blocking plate 8 are continuously arranged alternately so that the air supplied from the air supply pipe 7 passes through the outer space of the combustion gas pipe 3 inside the heating chamber 1 to warm the air. Interfering with the path to the discharge port 9, the heat transfer time from the combustion gas pipe 3 becomes longer, resulting in higher thermal efficiency.

Specifically, the air supplied by the blower 6 moves to a gap formed between the cut portion 8b of the half-moon-shaped blocking plate 8 and the inner circumferential surface of the heating chamber 1, and the cut-out portion of the lower half-moon-shaped blocking plate 8. Contrary to (8b), it moves to a gap formed between the cut portion 8b of the upper half-wall blocking plate 8 and the inner circumferential surface of the heating chamber 1, which are staggered.

Air supplied into the heating chamber 1 by the blower 6 moves through a plurality of combustion gas pipes 3 vertically connected from the combustion chamber 1 to the combustion gas collection chamber 4 along the above path. Therefore, the heat transfer time from the high temperature combustion gas pipe 3 becomes long, and thermal efficiency improves.

As the thermal efficiency is improved, a small amount of fuel may be used to supply the warm air 10 of a desired temperature to a required place such as a vinyl house or a glass greenhouse.

The agricultural hot air heater according to the present invention as described above has a half-moon-type blocking plate 8 in the transverse direction of many high temperature combustion gas pipes 3 vertically connected from the combustion chamber 1 to the combustion gas collection chamber 4. (1), the cut portions 8b of the half-moon blocking plate 8 are alternately arranged so as to extend the time for heat transfer from the combustion gas pipe 3 to air and to increase the heat transfer area. It is a useful design that improves the heating efficiency by using fuel, and also enables the reduction of the heating cost due to the reduction of the fuel used and the unit cost of the produced product.
