Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a kitchen waste residue-water-oil separation device. Background Technology

[0002] In the catering industry, a large amount of oil-water mixture is generated daily, containing food residue. The oil in this mixture needs to be collected, processed, and reused, necessitating oil-water separation. Existing technologies include some oil-water separation devices, such as Chinese utility model patent CN220245668U, which discloses an oil-water separator for kitchen wastewater. This separator features an inclined structure at the top of the baffle, resulting in a larger liquid outflow area and thus reducing the outflow velocity, ensuring effective oil-water separation. The inclined structure also alters the liquid's path, preventing it from directly impacting the oil layer. However, this patent only achieves oil aggregation; the oil accumulated on the upper layer still needs to be manually removed, which is inconvenient. Chinese invention application CN106890483A discloses an oil-water separator and a method for oil-water separation using the oil-water separator. The oil is collected by a conveyor belt and a scraper. A prerequisite for the oil collection in the above application is that the liquid level undulation is small. If the water volume is large and the liquid level rises sharply, more water will enter the oil collection tank, affecting the separation effect. Utility Model Content

[0003] The purpose of this invention is to provide a kitchen waste residue-water-oil separation device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a kitchen waste residue-water-oil separation device, comprising a rectangular box and a filter basket. An inlet pipe and an outlet pipe are respectively installed at opposite ends of the box. Multiple vertical partitions are fixedly connected to the inner cavity of the box, with the height of the partitions being less than the height of the inner cavity of the box. A vertical insert is fixedly connected to the inner cavity of the box, with the insert located between two partitions. The partitions and inserts are arranged along the length of the box and staggered vertically to form a wave-shaped waterway. An inclined plate assembly is fixedly installed in the rising section of the waterway. An oil suction mechanism is inserted downwards from the upper end of the insert. The oil suction mechanism includes a rectangular float box. A frame-shaped oil suction pipe is fixedly connected to the outer side of the float box. Multiple oil suction holes are provided on the lower side of the oil suction pipe. The bottom surface of the float box is lower than the oil suction holes. A rectangular insert is provided at the bottom of the oil suction pipe, and the insert is adapted to be inserted into the insert.

[0005] Preferably, a support block is fixedly connected to one side inner wall of the box and the adjacent partition, and the support block supports the upper edge of the filter basket.

[0006] Preferably, the lower end of the insert is an arc surface, and the side wall of the housing is welded with an oil suction pipe that connects to the insert.

[0007] Preferably, it also includes an oil tank, a negative pressure tank, and a vacuum pump. The vacuum pump is used to evacuate the negative pressure tank. The negative pressure tank and the oil tank are connected by a solenoid valve, and the oil tank is connected to the oil suction pipe by a pipeline.

[0008] Compared with the prior art, the beneficial effects of this utility model are: the oil suction mechanism of this utility model floats on the liquid surface during operation, and is not affected by sudden changes in the amount of input sewage, thus ensuring the stability of the separation and treatment effect.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Please see Figure 1 This utility model provides a technical solution: a kitchen waste residue-water-oil separation device, including a rectangular box 1 and a filter basket 3. The box 1 has an inlet pipe and an outlet pipe installed at opposite ends. Multiple vertical partitions 2 are fixedly connected to the inner cavity of the box 1. Support blocks 4 are fixedly connected to one inner wall of the box 1 and to adjacent partitions 2, supporting the upper edge of the filter basket 3. The filter basket 3 is used to filter out fixed residues in the kitchen wastewater. The height of the partitions 2 is less than the height of the inner cavity of the box 1. Vertical inserts 6 are fixedly connected to the inner cavity of the box 1, located between two partitions 2. The partitions 2 and inserts 6 are arranged along the length of the box 1 and staggered vertically to form a wave-shaped waterway. An inclined plate group 5 is fixedly installed in the rising section of the waterway, increasing the area and efficiency of oil-water separation.

[0015] The sleeve 6 is inserted downwards from the upper port to form an oil suction mechanism 7. The oil suction mechanism 7 includes a rectangular float 71. A frame-shaped oil suction pipe 72 is fixedly connected to the outside of the float 71. The lower side of the oil suction pipe 72 is provided with multiple oil suction holes 73. The bottom surface of the float 71 is lower than the oil suction holes 73. A rectangular insert 74 is provided at the bottom of the oil suction pipe 72. The insert 74 is adapted to be inserted into the sleeve 6. The float 71 rises and falls synchronously with the water level.

[0016] The lower end of the socket 6 is an arc surface, and the side wall of the housing 1 is welded with an oil suction pipe that connects to the socket 6. It also includes an oil tank 8, a negative pressure tank 9, and a vacuum pump 10. The vacuum pump 10 is used to evacuate the negative pressure tank 9. The negative pressure tank 9 is connected to the oil tank 8 via a solenoid valve, and the oil tank 8 is connected to the oil suction pipe via a pipeline. A normally closed proximity switch is installed between the top of the socket 6 and the float box 71. When the float box 71 floats, the circuit closes, the solenoid valve is energized and opens, evacuating the oil tank 8 to generate negative pressure, thereby allowing the oil suction pipe 72 to suck up the oil floating on the upper layer.

[0017] Working principle: Kitchen wastewater is poured into filter basket 3 through the inlet pipe or directly. Filter basket 3 filters out the fixed residue in the kitchen wastewater. The wastewater flows along the wavy waterway to one end of the outlet pipe. The oil suction mechanism 7 floats on the liquid surface. The oil suction pipe 72 located outside the float box 71 draws away the accumulated oil on the upper layer to achieve oil-water separation.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
