Description

Dehydrator for food waste {A DEHYDRATOR FOR FOOD GARBAGE}

The present invention relates to a food waste dehydrator for depressurizing and compressing dehydration by injecting food waste collected from various places into a pulverizer and crushing metals, plastics, and tough fibers such as fibrous materials. The present invention relates to a dehydrator for food waste, which is capable of increasing the dehydration efficiency by minimizing the outflow of particulates from the soil.

The food waste dehydrator in this field is equipped with an electric pressure screw in a cylinder type dehydration container made of perforated plate or a cylinder type dehydration container made of wedge wire, and when the food waste is put into the input port of the dewatering container using a screw conveyor, The leachate is slowly compressed while being pushed out and is discharged into the dehydration hole of the dehydration container, and the dehydrated squeezed material (food waste) is discharged to the outside through the discharge port formed at the end of the dehydration container.

The dehydrator for food waste is one in which a noodle-type press screw is applied to a noodle-type dehydration container (Utility Model Registration No. 331699) for the purpose of improving dehydration efficiency, and the latter conveying blade of the press screw is made smaller in pitch than the feed vane in the first half. (Patent No. 828273), and a feed screw provided by alternately arranging a transfer blade having a large pitch and a small pitch are applied (Utility Model Registration No. 320023).

In addition, the dehydration hole of the dehydration container is generally a circular hole of constant size, a sloping diagonal hole in the axial and circumferential directions, and an axially long and narrow pinhole in the circumferential direction such as a wedge wire.

In the second part of the process of dehydrating food waste in the food waste dehydrator, the moisture content of food waste is lower than that of the first half.

Nevertheless, it is difficult to increase the dehydration efficiency by depressing food waste at constant velocity or by dewatering using a feed screw having a feed blade with a small pitch in the latter half.

In addition, since it is difficult to suppress the outflow of fine particles, the turbidity of the leachate is high and the water treatment cost is further increased.

Accordingly, an object of the present invention is to provide a dehydrator for food waste which can increase the dehydration efficiency in the latter part of the dehydration container and lower the turbidity of the leachate in the section.

In order to achieve the first object, the present invention is roughly divided into the first half and the second half of the dewatering hole of the dehydration tube installed to surround the pressure screw screw as shown in FIG. Is characterized in that the dehydrator for food waste, which dehydrates quickly and has reduced moisture content during the first half of the dehydration container, improves the compressibility while suppressing the outflow of fine particles of food waste.

Since food dehydration at the beginning of high moisture content is promoted through the dehydration hole in the first half of the large-sized dehydration container, the water content is drastically lowered, and then the dehydration proceeds through the lower dehydration hole in the small pore size. Dewatering efficiency of food waste is higher than that of

In addition, since the pore size of the latter dehydration hole is small, the amount of food waste fine particles to escape during dehydration is significantly reduced compared to the larger portion of the first dehydration hole. Therefore, the turbidity of the leachate can be lowered, and the subsequent leachate purification cost reduction is also expected.

4 is another embodiment of the dehydration container

In Figure 1, the dehydrator 10 and the food waste storage bin 20, the food waste input device 30, the leachate storage bin 40 is a bundle of food waste dehydration equipment to form.

The dehydrator (10) has a pressure screw (13) is built into the dehydration container (11) in which the dehydration hole is tightly drilled on the main surface, and the inlet (14) of pure food waste is inserted at the beginning of the dehydration container (11) and compressed at the end. The discharge port 15 through which water is discharged is formed, and the pressure feed screw 13 is operated by the motor 16 provided in the terminal of the dehydration container 11.

The pressure feed screw 13 applied to the present invention has a structure in which the central axis is gradually thickened toward the rear end as shown in FIG. 2, and the pitch of the latter half feed vanes 13b is gradually smaller than that of the first half feed vanes 13a. Say that.

The prominent point here is the dehydration hole given to the dehydration container 11 surrounding the outer periphery of the screw screw 13. 2 and 3, the pore size of the second half dewatering hole 12b is smaller than that of the first half dehydration hole 12a based on the direction in which the food waste is conveyed.

Food waste at the time of introduction into the inlet 14 is very dehydrated because the water content is very high. The reason why the first part of the dewatering hole 12a of the dewatering tube 11 has a large pore is to promote dehydration.

During the feeding process, most of the leachate in the food waste is dehydrated to the first dehydration hole 12a, and then the remaining leachate can be smoothly decompressed through the compression by the press screw 13 to the second dehydration hole 12b having a smaller pore diameter. .

As shown in FIG. 3, changing to a dehydration hole where the pore size gradually decreases toward the rear end of the dehydration tube 11 may also obtain an equivalent effect.

For reference, a pump 31 is provided on the outlet of the food waste storage container 20, and a pressure feeding pipe 34 leading to the inlet 14 is connected to the discharge port of the pump 31.

The pump 31 and the pressure feed pipe 34 are food waste injectors, and are capable of a compact and lightweight design compared to a conventional screw conveyor, and are provided with vehicle transportation and installation convenience in the field.

At the rear end of the pressure feed pipe (34) adjacent to the inlet (14), a bypass pipe (32) directed to the food waste storage container (20) is provided, and the bypass pipe (32) is connected to the valve (33). It is to be controlled.

When the amount of food waste input by the pump 31 is larger than the amount of food waste conveyed for the purpose of dehydration by the pressure feed screw 13, the pressure feed screw 13 and the dewatering container 11 are excessively loaded.

In this case, the valve 33 is opened so that the excess food waste is returned to the food waste storage container 20 through the bypass pipe 32, so that the dehydrator 10 is smoothly dewatered together with the dehydration container 11 and the pressure screw. Mechanical protection is possible by preventing overload of (13).
