The present invention relates to a food waste dehydrator, and more specifically, to adjust the distance between the screen and the compression screw to adjust the pressure applied to the food waste conveyed by the compression screw, it is easy to remove foreign substances caught in the water hole of the screen A food waste dehydrator that can be separated.

Along with the development of the industry, the economic requirements are increased, and the living environment is improved, and a large amount of garbage is emitted.

Among these wastes are recyclable wastes such as paper or metal and food wastes. These wastes are usually landfilled, incinerated or recycled.

However, among these wastes, food wastes are treated by landfilling or composting by separating them from other recyclable wastes. However, since food wastes contain a large amount of water, the waste water is discharged during the transport to the treatment plant, causing a bad smell. In the case of landfills in landfills, there is a problem that withdrawal water contaminates land in landfills.

Accordingly, various devices for removing water from food waste have been developed and provided, and these dewatering devices have a dewatering screen, and a conventional food waste disposal dewatering device having such a dewatering screen has water passing formed on the screen. The ball was clogged by foreign matter and did not remove enough moisture, which caused many difficulties in transportation or treatment.

In addition, the conventional dewatering device has a disadvantage in that the distance between the screen and the compression screw is not adjusted, so when the amount of food waste is not large, the food screw is caught between the compression screw and the screen, and the compression screw cannot transport the food waste. .

In order to solve the above problems, the applicant has proposed a domestic patent application 2006-089377 (name: food waste dehydrator).

Korean Patent Application No. 2006-089377 (name: food waste dehydrator), by adjusting the height of the screen using the screen height adjustment mechanism can adjust the space between the screen and the compression screw to prevent food waste leaks between the screen and the compression screw It prevented the water hole from being blocked by spraying high pressure water from the outside of the screen to separate foreign substances caught in the water hole of the screen.

In addition, by freely adjusting the distance between the pressure plate and the housing, the space between the discharge port formed in the pressure plate and the housing, that is, the width of the discharge passage, may be adjusted to control the amount of food waste transported by the screw. By adjusting the pressure applied to the food waste transported by the skews, it is possible to control the degree of discharge of water from the pressurized food.

However, the load acting on the pressure plate is not uniform, and the shaft supporting the pressure plate may be bent, and the power transmission device of the sprinkling ring transfer device installed to spray high pressure water may be connected to the chain. The structure is complicated by using the pulley, and in the case of long food waste dehydrator, the chain is drooped and the power is lost, so the power is not transmitted well.
