Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen waste treatment, and in particular relates to an oil-water-solid separation device. Background Art

[0002] Oil-water separator is a kind of device, which is divided into two types: catering oil-water separator and industrial oil-water separator. Catering oil-water separator is used to treat sewage in the catering industry. Due to environmental protection requirements, the sewage generated by the ship machinery space discharged into rivers, lakes and seas must be treated, and an industrial oil-water separator is required.

[0003] The catering oil-water separator is a box structure that can be buried underground or on the ground. After the non-slip box cover is opened, the sewage flows into the residue collection chamber through the inlet, leaving solid matter behind. The sewage flows into the grease collection chamber through the lower edge of the partition. After gravity separation, a large amount of grease floats on the surface. The de-oiled sewage flows into the grease collection chamber through the lower edge of the partition. The grease is separated and floats to the surface again. The de-oiled sewage outlet flows into the unified standard water sampling room specified by the National Environmental Protection Agency for easy sampling and discharge through the discharge pipe. The entire grease collector is finely designed, reasonable, small in size, and highly efficient. The raw materials are stainless steel and fiberglass.

[0004] The existing technology has the following problems: the oil-water-solid mixed liquid is separated by a filter net, and the proportions of each component in the oil-water-solid mixed liquid are uncertain. When the proportion of solids is high, the solids separated by the filter device cannot be discharged in time, and the staff needs to frequently replace the filter element, resulting in reduced work efficiency.

[0030] Working principle: The staff closes the discharge pipe 17, and the liquid with higher temperature enters the heating chamber 23 through the high-temperature pipe 24 to preheat the sedimentation tank 3. The water outlet pipe 6 is closed, and the oil-water-solid mixed liquid enters the filter device 10 through the feed pipe 12. The medium-speed motor 14 in the filter device 10 drives the stirring blade 15 on the transmission shaft 13 to rotate. The stirring blade 15 drives the liquid to rotate and breaks up the larger solids at the same time. In the rotating liquid, the solid particles will gather in the middle. When the solids in the filter box accumulate to a certain height, the discharge pipe 17 is opened, and the high-speed motor 22 is started. The high-speed motor 22 drives the spiral blade 19 on the rotating shaft 18 to rotate. The spiral blade 19 pushes the solid to leave the device through the discharge pipe 17, and the oil-water mixed liquid in the filter box is The oil-water mixture enters the sedimentation tank 3 through the water inlet pipe 9, and the baffle 21 makes the oil-water mixture enter in an upward direction. When the oil-water mixture reaches a certain height, the low-speed motor 4 drives the stirring rod 8 to slowly stir the oil-water mixture. Since the liquid in the sedimentation tank 3 is in a low-speed rotation state, the oil-water mixture enters and rotates with the liquid. Since the density of oil is smaller than that of water, the oil floats on the water surface. The supercharger reduces the pressure at one end of the oil outlet pipe 5 close to the sedimentation tank 3, so that the oil can leave the device more easily. The sludge density in the oil-water mixture is greater than that of water, and the sludge is deposited at the bottom of the sedimentation tank 3. When the sludge reaches a certain height, the electric valve in the sludge discharge pipe 7 is opened, and the sludge leaves the device through the sludge discharge pipe 7. The density of water is between that of sludge and oil, and it leaves the device through the water outlet pipe 6.
