Abstract

(57) [Abstract] [Purpose] Drying dung of livestock in a thermal dryer that supplies hot air from one end of a drum rotating around a horizontal axis and discharges exhaust gas from the other end through a chimney. , It is performed uniformly in a short time and enhances the deodorizing effect of exhaust gas. [Structure] A plurality of stirring projections 16 are provided on an inner wall portion of a drum 11 at intervals in and around the axial line,
A chemical reaction type deodorant spray 17 is provided on the chimney 15.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device uses livestock manure (cattle manure, chicken manure, etc.) and food production residue (okara, bread crumbs, beer residue, soy sauce residue, ham residue, etc.) (hereinafter referred to as dried material) through hot air (combustion gas). The present invention relates to a thermal power (hot air) dryer used for drying.

[0002]

[Prior art]

 In this type of thermal dryer, hot air is supplied from one end in the axial direction into a drum (cylindrical) that rotates around a horizontal axis, and the other end in the axial direction is passed through a chimney with a deodorizing device that is flushable. The one that emits exhaust gas is commonly used.

[0003]

[Problems to be solved by the device]

 However, in this conventional thermal dryer, stirring of the material to be dried in the drum is substantially limited to the surface layer, so it is difficult to obtain uniform drying even if the time is long. If it is low, there is a problem that the deodorizing effect of exhaust gas does not increase.

In view of the above problems, the present invention stirs the material to be dried in the drum (including the bottom) so that it is uniformly dried in a short time, and the odor concentration is low. Also aims to enhance the deodorizing effect of exhaust gas.

[0005]

[Means for Solving the Problems]

 According to this invention, the above object is to provide a plurality of stirring projections on the inner wall portion of the drum at intervals in the axial direction and in the direction around the axial line, and to use the deodorizing device as a chemical reaction type deodorant (deodorizing liquid). This is achieved by composing with a spray.

As the stirring protrusion, a plate-shaped, rod-shaped, or other appropriate shape can be used, while the chemical reaction type deodorant can be any of alkaline odor, acidic odor, and neutral odor depending on the chemical reaction. Alternatively, one that can decompose, neutralize, or absorb two or more can be used.

[0007]

[Action]

 In the thermal dryer of the present invention, the material to be dried is agitated at the surface layer portion by the rotation of the drum, and at the same time the inside is agitated by the plurality of agitating projections, so that the material to be dried is uniformly dried in a short time.

Further, the exhaust gas is decomposed, neutralized and absorbed by the chemical reaction type deodorant sprayed from the chemical reaction type deodorant spray regardless of the concentration of the odorous component, and is discharged in a substantially odorless state. .

【Example】

 The drawing illustrates an embodiment of the thermal dryer according to the present invention, in which the dried article inlet / outlet 12 (the one end facing the oil burner 13 and the other end facing the gas conduit 14 connected to the chimney 15 ( The drum 11 with a lid (not shown in the drawings) is rotatably supported by the machine frame 21 via a pair of support rollers 22 at each end in the axial direction, and from a motor 23 via a chain transmission mechanism 24. It is driven to rotate at a low speed (for example, several revolutions per minute).

The drum 11 is provided with a plurality of bent plate-shaped stirring protrusions 16 on its inner wall portion at intervals in both the axial direction and the axial direction, and the chimney 15 has an upper portion with a pump. A deodorant spray 17 is provided which receives a chemical reaction type deodorant having an appropriate concentration from a built-in deodorant tank 18.

In the thermal dryer of this illustrated example, the drum 11 loaded with an appropriate amount of the material to be dried (eg, about 1/3 to 1/4 of the diameter of the drum) is rotated at a low speed while the drum 11 is rotated. By introducing combustion gas from the oil burner 13 into the drum to bring the temperature inside the drum to, for example, 200 to 250 degrees Celsius, the material to be dried is placed under the drum 11 and dried while being stirred by the stirring projections 16. The deodorant is deodorized by contacting the exhaust gas discharged from the gas conduit 14 through the chimney 15 with the chemical reaction type deodorant sprayed from the deodorant spray 17 at the upper part of the chimney 15.

In addition to this, the present invention can be implemented in various forms, such as using pin-shaped stirring projections or distributing the stirring projections in a pattern not shown.

[0013]

[Effect of device]

 As is clear from the above description, according to the thermal dryer of the present invention, the material to be dried can be uniformly dried in a short time, and the deodorization of exhaust gas is highly efficient regardless of the odor concentration. There is a practically useful effect that can be performed in.
