Description

Technical field:

[0001] The utility model relates to the technical field of kitchen waste equipment, in particular to a kitchen waste oil-water separation device. Background technology:

[0002] Kitchen waste in the catering industry is a difficult problem in the environmental protection treatment of the catering industry; especially in the hot pot industry, there is a lot of oil in the bottom of the pot, and directly discarding it will cause a large waste of edible oil; collecting the waste edible oil generated in the catering industry is the first step in the environmental protection treatment of edible oil in the catering industry. It is of great significance to effectively recycle and treat the waste edible oil in the catering industry, turning waste into treasure, and becoming green and environmentally friendly biofuels and feed industry oils, reflecting the maximum value of renewable resource products. At present, the oil-water separation device in the kitchen waste disposer is not accurate in separating oil and water (for example, the static method allows the oil and water to separate). After the oil-water separation, there is still oil in the water, the oil-water separation is not thorough, and the separation efficiency is low; therefore, we need a kitchen waste treatment oil-water separation device to solve the above problems. Utility model content:

[0003] The utility model aims to provide a kitchen waste oil-water separation device to solve the technical problems of incomplete oil-water separation and low separation efficiency in the prior art oil-water separation device.

[0004] Contents of the utility model: A kitchen waste oil-water separation device, comprising a refrigerator with an opening at the lower end, a pneumatic bottom plate assembly is arranged at the bottom end of the refrigerator, a feed port is opened on the refrigerator, a filter screen is installed on the feed port, a feed trough is installed outside the feed port, a plurality of oil drain pipes are arranged on the side wall of the refrigerator, a ball valve is installed on the oil drain pipe, a first cylinder is installed on the top end of the refrigerator, a piston rod of the first cylinder is connected to an extrusion plate, and the extrusion plate is slidably connected to the inner wall of the refrigerator.

[0005] Furthermore, the pneumatic bottom plate assembly includes a bottom plate, the bottom plate is used to seal the refrigerator, the bottom plate is connected to the piston rod of the second cylinder, and the second cylinder is installed on the outer wall of the refrigerator.

[0006] Furthermore, a movable plate is arranged on the bottom plate, a slide rod is connected to the movable plate, a slide groove is opened on the bottom plate, a compression spring is installed in the slide groove, and the slide rod is slidably connected to the slide groove.

[0007] Furthermore, a sealing ring is installed on the bottom plate.

[0008] Furthermore, a transparent observation window is installed on the outer wall of the refrigerator.

[0009] Furthermore, an aeration pipe is installed on the refrigerator, and the aeration pipe is located below the oil drain pipe.

[0010] The beneficial effects of the utility model are as follows: the utility model has a simple structure, rationally utilizes the solidification point characteristics of vegetable oil, designs a refrigeration type oil-water separation device, and maintains the temperature of the oil-water separation device at about minus five degrees, so that water can be solidified while the vegetable oil is still in a liquid state, thereby making the oil-water separation more clear and thorough, facilitating the thorough separation of oil and water, and improving the efficiency of oil-water separation, and is worthy of popularization and use.

[0012] Figure 2 This is the front view of the filter box of the utility model;

[0013] Figure 3 for Figure 2 Section view along AA;

[0014] In the figure, a refrigerator 1, a first cylinder 2, a second cylinder 3, a feed trough 4, a filter screen 5, an oil drain pipe 6, an aeration pipe 7, a bottom plate 8, a moving plate 10, a slide bar 11, a compression spring 12, an extrusion plate 13, and an observation window 14 are shown. Specific implementation method:

[0015] like Figures 1 to 3 As shown, a kitchen waste oil-water separation device comprises a refrigerator 1 with an opening at the lower end, a pneumatic bottom plate assembly is arranged at the bottom end of the refrigerator 1, a feed port is opened on the refrigerator 1, a filter screen 5 is installed on the feed port, a feed trough 4 is installed outside the feed port, a plurality of oil drain pipes 6 are arranged on the side wall of the refrigerator 1, a ball valve is installed on the oil drain pipe 6, a first cylinder 2 is installed on the top of the refrigerator 1, a piston rod of the first cylinder 2 is connected to an extrusion plate 13, and the extrusion plate 13 is slidably connected to the inner wall of the refrigerator 1; the pneumatic bottom plate assembly comprises a bottom plate 8, the bottom plate 8 is used to seal the refrigerator 1, and the bottom plate 8 is connected to the piston rod of the second cylinder 3, and the second cylinder 3 is installed on the outer wall of the refrigerator 1; in order to facilitate the rapid separation of ice cubes from the bottom plate 8, a movable plate 10 is arranged on the bottom plate 8, a slide rod 11 is connected to the movable plate 10, a slide groove is opened on the bottom plate 8, a compression spring 12 is installed in the slide groove, and the slide rod 11 is slidably connected to the slide groove; a sealing ring is installed on the bottom plate 8; in order to facilitate the observation of the liquid level in the refrigerator 1, a transparent observation window 14 is installed on the outer wall of the refrigerator 1; in order to make the vegetable oil float quickly, an aeration pipe 7 is installed on the refrigerator 1, and the aeration pipe 7 is located below the oil drain pipe 6.

[0016] Since the freezing point of mainstream vegetable oils is around minus 10 degrees (for example, the freezing point of peanut oil is -15°C, soybean oil is -18°C, rapeseed oil is -20°C, and sunflower oil is -10°C), the temperature of the refrigerator can be maintained at around -5°C. During specific operation, kitchen waste is added to the feed trough 4, the filter 5 separates the solid impurities, the refrigerator 1 is adjusted to a temperature of minus 5 degrees, and compressed air is introduced into the aeration pipe 7 for a short time, so that the vegetable oil in the kitchen waste can float up quickly to complete stratification. After standing for a period of time, the water at the bottom solidifies into ice, while the vegetable oil is still in liquid state. At this time, the first cylinder 2 can be started to press down, so that the vegetable oil is discharged from the oil drain pipe 6 (different oil drain pipes 6 are opened according to different liquid level positions). At this time, the second cylinder 3 can be opened to lower the bottom plate 8, so as to take out the ice cubes.

[0017] The above are only preferred examples of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
