Description

Surface drying machine of organic wastes

The present invention relates to a flotation drying apparatus for organic wastes for drying and processing food wastes, animal waste, sludges, organic wastes, and other materials that require drying to reduce feed and organic fertilizers and other minimum weight loss.

In general, a number of organic waste drying apparatuses in the form of a drying furnace have been introduced, including most of the inventors of the present invention by rotating the drying furnace to which the heat of the burner is supplied. It was made of a device to be dried by the process of being transported while being plunged by a transfer blade attached to the.

However, because the size and length of the drying furnace are considerably large, the weight is excessively high, and when a large amount of organic matter such as food waste is put into the drying furnace, it is rotated by a motor, so the overload and failure rate of the driving device increase the maintenance and repair costs. There was a problem with high back.

The present invention is proposed to solve the above problems,

first; The high moisture content to be dried was difficult to dry in the conventional pipeline drying furnace, but this was solved by the function of floating and conveying.

second; It enables the shaftless and high speed rotation of the screw, and the phenomenon of sticking to the screw due to high viscosity, etc. later solved the problem of not being transported or dried as a thick column.

third; The screw member is shaped like a donut to smooth the flow of air flow through the blade, increasing the drying power.

fourth; High speed rotation of the screw member allows the to-be-dried material to float and the to-be-dried material above the screw blade height is not transferred to maintain a sufficient residence time.

fifth; Structurally, in the prior art, because the structurally horizontal, the bending phenomenon could not but occur only by the tension of the shaft, but solved by configuring the external fixed type.

The purpose is to provide a floating drying apparatus of the organic waste as described above.

As in Figures 1 to 3,

The drying furnace 30 inserted through the center of the granular frames 20 installed in a plurality at equal intervals on the base 10 is supported by the support members 40 on all sides of the granular frames 20. It is fixed to form an inlet 31 for injecting the object to be supplied by the transfer means 120 on the inlet side of the drying furnace 30 and the outlet 32 is formed on the outlet side.

A screw member 70 is installed in the drying furnace 30 so as to be driven by the motor 60 by connecting only the both ends to the drive shaft 50.

The heat source supply member 80 installed at the inlet side of the drying furnace 30 to supply a heat source in the drying furnace 30 is supplied with a heated heat source of the burner 82 through a hopper-type combustion furnace 81. It is.

In addition, the heat source or the gas passing through the drying furnace 30 is collected and discharged to the outside by collecting the dust by the discharge line 110 and the cyclone 100 toward the dry object inlet 31.

1 and 4, the steam pipes 33 and 33 'connected to the steam line 91 of the steam device 90 are connected to both ends of the drying furnace 30 by steam connecting means 34, respectively. The steam was circulated.

The steam connecting means 33A is one side of the cutaway groove 331 in a state in which the steam pipe 33 formed with the cutout groove 331 is wrapped around both ends of the jacket 35 formed on the outer surface of the drying furnace 30. Connected to the drying furnace 30 and the other side is connected to the jacket 35 so that the steam is circulated into the jacket 35 to supply the heat source of the heat medium by the steam to the drying furnace (30).

5 and 6, the support member 40 is installed so as to penetrate the granular frame 20 installed at equal intervals to support the drying furnace 30, the sliding formed on all sides of each of the granular frame 20 The support bar 41 fitted to the ball 21 is connected to the ground piece 42 which is grounded to the drying furnace 30, and to the fixing piece 43 fixed to the granular frame 20 to the outside of the support bar 41. The support bar 41 is pressed by the pressing of the spring 45 which is fastened to the bolt 44, and is configured to elastically support the drying furnace 30 from all directions.

As shown in Figure 7, the screw member 70 is connected to the plate body 72 long in all four sides of the closing plate 71, and install a support plate 73 for connecting the plate bar 72 at appropriate intervals, each Starting with the plate bar 72 and connecting the blade piece 74 in the helical direction, respectively, the blade piece 73 connects another blade piece 75 at each position in contact with the next plate bar 72 repeatedly. The blade pieces 74 and 75 each form a shape in which each blade piece is twisted like a donut shape. And the drive shaft 50 is connected to only a part of the closing plate 71 and the support plate 73 on both sides so that the drive shaft 50 is connected to both ends of the screw member 70 as a whole, so that there is no shaft inside The structure is designed to complement each other so as to have elasticity while minimizing the occurrence of warpage.

Looking at the operating state of the present invention configured as described above are as follows,

According to the present invention, when the driving source of the motor 70 rotates by the power transmission device, the screw member 70 connected to both ends of the driving shaft 50 rotates at a high speed in the drying furnace 30. At the same time, the heated heat by the burner 82 is supplied into the drying furnace 30 through the combustion furnace 81 by the operation of the heat source supply member 80. In addition, the steam generated by the operation of the steam device 90 is circulated through the steam line 91 into the jacket 35 connected to the steam pipes 33 and 33 'installed at the inlet and outlet sides of the drying furnace 30. Another heat source for heating the outer wall of the drying furnace 30 is to provide to the drying furnace (30).

In this state, when a dry material such as food waste is put into the inlet 31 of the drying furnace 30 by a separate conveying means 120, the screw member 70 which is rotated at a high speed inside the drying furnace 30 is avoided. At the same time, the dried material is transported by spiral blades 74 and 75, and the dry matter is continuously floated toward the inner wall of the drying furnace 30 so that the transport is gradually performed.

This is because the to-be-dried material having a high moisture content, viscosity, etc. is floated to the outside due to the fragmentation due to the high speed, so that the to-be-dried material does not adhere to the inside of the screw member 70, thereby forming a space portion, thereby communicating heat by the heat source supply member 80. Not only does it impede, but the blades (74, 75) or more height is not transferred to maintain the dwelling time is sufficient to maintain the dense particle distribution even in the narrow space to increase the contact of the hot air stream to increase the drying power, In addition, when the object to be lifted to contact the inner wall of the drying furnace 30 is to increase the drying power by indirect heat due to steam in the jacket (35).

By this process, the dried organic material which is transported while being gradually dried toward the heat source supply member 80 and discharged to the discharge port 32 may be used as a feed or organic fertilizer by being transported or packaged by a separate transport means.

When explaining the characteristic effects of the present invention as described above,

First: a jacket was provided on the outer wall of the drying furnace to double the drying power in the drying furnace 30 by providing a steam heating medium.

Second: As the screw member is shaftless while forming donut shape, it improves the drying power by smoothly transferring steam or airflow.

Third: Since the screw member is configured to be rotated at high speed, the particles to be dried are floated while being floated, so that the residence time is sufficiently maintained to facilitate the drying treatment of the dried product having high moisture content and high viscosity.

Fourth: screw members are complemented to each other outside the structure to minimize the warpage phenomenon in the correction device and improved functionality by giving elasticity.

Fifth: The phenomenon of sticking of the dry matter to the screw is removed and the volume occupied by the screw is minimized to maximize the drying space.
