Description

Technical Field

[0001] This utility model belongs to the field of kitchen waste treatment, and specifically relates to an integrated kitchen waste drying treatment device. Background Technology

[0002] Food waste is characterized by high water content, high organic matter content, and easy decomposition and odor. It needs to be dried to facilitate subsequent treatment and processing, and can be transformed into new resources. Its high organic matter content means that after strict treatment, it can be used as fertilizer and feed, or it can produce biogas for fuel or power generation. The separated oil portion can be used to prepare biofuel.

[0003] The core principle of food waste drying technology is to heat the waste with an external heat source, causing the liquid water (including free water and some bound water) to evaporate, thus obtaining a dried product with extremely low water content. Currently, food waste drying processes only involve heating the waste, allowing the oil to separate by gravity, without any squeezing or pushing action, resulting in low drying efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an integrated kitchen waste drying treatment device that can improve the oil-water separation efficiency of kitchen waste, so that the oil-water mixture in the kitchen waste can be fully extracted, thereby improving the drying treatment efficiency of kitchen waste.

[0005] The purpose of this utility model is achieved as follows: An integrated kitchen waste drying and treatment device includes a rectangular shell. A horizontal partition plate is horizontally arranged inside the shell, dividing the interior into an upper cavity and a lower cavity. An inlet is located at the top of the shell, and a drop outlet is located on the other side of the partition plate. A vertical limiting partition plate is located in the upper cavity corresponding to the drop outlet, and the limiting partition plate is connected to a lifting drive mechanism at the top of the shell. A horizontal pressure plate that can move up and down is located in the upper cavity, and the pressure plate is connected to the lifting drive mechanism. A pusher plate is located in the upper cavity corresponding to the limiting partition plate, above the partition plate, and is connected to the pusher drive mechanism. Multiple separation holes are located on the partition plate corresponding to the pressure plate. Several hot air connectors are located on both the left and right sides of the shell. A rotating shaft is rotatably and horizontally arranged in the lower cavity, with spiral blades on the rotating shaft. An outlet is located at the bottom of the shell corresponding to the rotating shaft, and multiple separation holes are located on the bottom wall of the shell in front of the outlet.

[0006] In operation, kitchen waste enters the upper cavity of the housing through the feed inlet. Then, the pusher plate pushes the kitchen waste downwards towards the pressure plate. The limiting partition descends to the dividing plate. Hot air is introduced into the kitchen waste between the pusher plate and the limiting partition to soften the solid grease. After softening, the pressure plate squeezes the kitchen waste. The oil and water enter the lower cavity through the first separation hole. The rotating shaft rotates to throw out the oil and water to prevent them from sticking together. The oil and water enter the collection tank through the second separation hole. After the squeezing is completed, the limiting partition rises, and then the pusher plate pushes the kitchen waste into the lower cavity through the drop inlet. The rotating shaft rotates and pushes the kitchen waste towards the discharge port through the spiral blades. During the squeezing process, the oil and water also enter the collection tank through the second separation hole. The solid waste is discharged through the discharge port, and the separated oil and water enter the collection tank. Compared with the prior art, the beneficial effects of this utility model are as follows: by using integrated upper and lower cavities to squeeze and separate oil and water, the oil-water separation efficiency of kitchen waste can be improved, so that the oil-water mixture in kitchen waste can be fully extracted, thereby improving the drying treatment efficiency of kitchen waste.

The drive cylinder drives the limiting partition to move up and down, and the limiting partition is movably connected to the housing.

[0009] As a further improvement of this utility model, the second lifting drive mechanism is located on the top of the housing. The second lifting drive mechanism includes a vertical bracket installed on the top of the housing, on which a second driving cylinder is mounted. The piston rod of the second driving cylinder faces downward. At least four lifting rods are connected to the upper side of the pressure plate. Each lifting rod extends out of the housing and is movably connected to the housing. The top end of each lifting rod is fixed to the lifting plate.
