Detailed Description
The invention will now be described in more detail by way of example with reference to the accompanying drawings in which:
referring to fig. 1-8, the invention provides a multi-stage oil-water separation device for catering, comprising: main tank 1, cyclone separator 2. The cyclone separator 2 is used for first-level centrifugal separation, and the main tank body 1 is used for second-level gravity separation.
The cyclone separator 2 is composed of a spiral pipeline 2.1 and a corrugated plate 2.2 and is arranged in a double-layer structure at the lower half part of the main box body 1. The corrugated sheets 2.2 are uniformly distributed in the pipe 2.1 along the spiral line of the spiral pipe. The incoming flow oil-water mixture enters the cyclone separator 2 through the inlet, and the oil-water mixture is subjected to primary centrifugal separation in the pipe. In addition, the corrugated plate 2.2 promotes the oil drops to be coalesced into large oil drops in the centrifugal separation process, and secondary gravity separation is facilitated. The orifice plate 1.2 welds in box 1.1 inner circle baffle lower extreme, and cowling panel 1.3 welds in box 1.1 middle part, and cowling panel 1.3 face is perpendicular with the delivery port. The oil outlet disc 1.5 and the box body 1.1 are coaxially arranged, the oil outlet pipe 1.4 is arranged at the lower end of the oil outlet disc 1.5, the oil outlet pipe 1.4 and the oil outlet disc 1.5 are supported and limited through an oil outlet disc support frame 1.6, and the oil outlet disc support frame 1.6 is connected with the barrel wall of the box body 1.1 through bolt connection. An oil scraping plate 1.7 is arranged at the upper end of the oil outlet disc 1.5, and the oil scraping plate 1.7 is driven by a motor 1.8.
The lower half part is a box body with a double-layer structure. The inner ring baffle ensures that the oil-water mixture is smooth in the main tank body, and is favorable for stably carrying out secondary gravity separation. The orifice plate 1.2 can balance the flow velocity of the oil-water mixture on the left side and the right side of the box body 1.1 to a certain degree, and is beneficial to more stably carrying out secondary gravity separation. The fairing plate 1.3 is arranged along the axial direction of the box body. The rectifying plate 1.3 can weaken the rotational flow of the oil-water mixture in the barrel, maintain the whole flow in the vertical direction and facilitate the two-stage gravity separation more stably. Each group has three corrugated plates 2.2, which are arranged in parallel in the spiral pipeline 2.1. The surface of the rectifying plate 1.3 is vertical to the water outlet, which is beneficial to the smooth discharge of the water phase. The orifice plate 1.2 is provided with three large-diameter round holes, and the resistance is low while the large-diameter round holes stably flow. An oil outlet disc 1.5 and an oil outlet pipe 1.4 in the box body are supported and limited by an oil outlet disc support frame 1.6.
The working process is as follows: the oil-water mixture enters the main tank body 1 through the cyclone separator 2, primary centrifugal separation is carried out in the cyclone separator 2, and small oil drops in the oil-water mixture are coalesced into large oil drops under the action of the corrugated plate 2.2. The oil-water mixture enters the main tank body 1 for secondary oil-water separation through primary centrifugal separation, and the inner hole plate 1.2 and the rectifying plate 1.3 in the tank body 1.1 have a stabilizing effect on liquid flow. The oil drips and floats on the surface of water and forms the oil slick layer, and when the oil slick layer reached oil dish 1.5 quotation height, the grease was scraped into oil dish 1.5 by frizing 1.7 and is flowed out through oil outlet pipe 1.4. The separated water phase flows out of the box body 1 through the water outlet pipe 3.
