[0020] A degreasing and purification sedimentation tank for grease-containing wastewater comprises a sedimentation tank body 1, a pretreatment box 2 is connected to one side of the sedimentation tank body 1, a limiting frame 3 is provided at one side of the top of the sedimentation tank body 1, a dosing box 4 is provided at one side of the inner part of the limiting frame 3 through integral molding, a water blocking weir 5 is provided at one side of the inner part of the sedimentation tank body 1, a limiting slide 8 is slidably connected to the other side of the inner part of the limiting frame 3, and a movable push plate 9 is fixedly connected to the bottom end of the limiting slide 8, a limiting rib 11 is fixedly connected to one side of the movable push plate 9, and a wiring sleeve 12 is fixedly connected to one side of the bottom end of the limiting rib 11, a heating rod 13 is provided at the bottom end of the wiring sleeve 12, and a telescopic rod 10 is provided at the lower right position of the limiting frame 3.
[0021] like Figure 1 and Figure 2As shown, a pre-screen plate 18 is mounted on the middle upper position of the inner side of the pretreatment box 2, and a cleaning chute 19 is connected to the middle upper position of the side of the pretreatment box 2 away from the sedimentation tank body 1. The cleaning chute 19 is a square hollow structure, and the cleaning chute 19 and the pre-screen plate 18 are relatively arranged. Since the cleaning chute 19 and the pre-screen plate 18 are relatively arranged, a certain degree of impurities are accumulated on the mesh surface of the pre-screen plate 18, and when the cleaning chute 19 is opened, the staff can use tools to sweep the impurities into the cleaning chute 19 so that the impurities accumulated on the mesh surface of the pre-screen plate 18 can be quickly removed; the bottom position of the dosing box 4 is connected to the discharge hopper 14, and the lower half of the discharge hopper 14 is a conical structure, and the bottom end position of the discharge hopper 14 is provided with a porous bottom plate 15 through integral molding, and the lower half of the discharge hopper 14 extends to the upper left inner side of the sedimentation tank body 1, when the chemical agent is directed toward the sedimentation tank body 1 When the chemical agent is put into the upper left side of the inner side, the bottom surface of the porous bottom plate 15 has a structural setting of multiple circular holes, which can homogenize the chemical agent so that it can be evenly fed into the inner side of the sedimentation tank body 1; a drain outlet 6 is provided at the middle and upper position of the water-blocking weir 5, and an inner inclined platform 7 is provided at the lower left position of the inner side of the sedimentation tank body 1, and the inner inclined platform 7 and the water-blocking weir 5 are integrally formed. A sewage hopper 16 is connected to the lower right position of the sedimentation tank body 1, and a spiral conveying bin 17 is connected to the discharge end of the sewage hopper 16. The sewage hopper 16 has a conical structure. When the oily wastewater is initially precipitated inside the sedimentation tank body 1, the equipment will divide the independent degreasing area through the water-blocking weir 5, so as to centrally remove the grease in the oily wastewater. At the same time, by arranging the sewage hopper 16 and the spiral conveying bin 17, it will be convenient for the later equipment to quickly discharge the precipitated waste residue outward by spiral conveying.
[0022] like Figure 2 , Figure 3 and Figure 4 As shown, the movable end of the telescopic rod 10 extends into the inner side of the limiting frame 3 and is connected to the movable push plate 9, the movable push plate 9 extends between the sedimentation tank body 1 and the water blocking weir 5, the connection between the movable push plate 9 and the limiting slide plate 8 forms a "T"-shaped structure, the limiting ribs 11 are arranged in an equidistant structure along the horizontal direction, and the movable push plate 9 and the heating rod 13 are arranged adjacent to each other at the left and right positions. When the telescopic rod 10 starts to reciprocate and push the movable push plate 9, the movable push plate 9 will carry the heating structure to reciprocate and horizontally push the grease on the surface of the oily wastewater, so that it can be pushed to the upper left side of the inner side of the sedimentation tank body 1, so that the subsequent equipment can perform centralized degreasing operations.
[0023] Working process: The electric energy used in the operation of the equipment in the utility model comes from an external power supply. When the degreasing purification sedimentation tank is used to treat grease-containing wastewater, the grease-containing wastewater will first enter the interior of the pretreatment box 2 and be pre-filtered through the pre-screen plate 18. Then, when the grease-containing wastewater after the initial filtration enters the degreasing area formed by the sedimentation tank body 1 and the water-blocking weir 5, the telescopic rod 10 will start to reciprocate and horizontally push the movable push plate 9, so that the drain port 6 is opened, and the movable push plate 9 can also push the grease on the surface of the grease-containing wastewater together with the heating structure to the upper left position of the sedimentation tank body 1. Then, after the wiring sleeve 12 electrically connected to the heating rod 13 is pre-connected to the external power supply, the dosing box 4 can be opened to allow the chemical agent to be dropped toward the upper left side of the inner side of the sedimentation tank body 1 through the discharge hopper 14 and the porous bottom plate 15. Then, under the auxiliary action of the auxiliary heating structure and the reciprocating concentrated oil pushing structure, after the heating state The grease-containing wastewater will be fully mixed and dissolved with the chemical agent so that the equipment can remove the grease floating on the surface of the grease-containing wastewater through chemical reaction. Then, the degreased wastewater enters the lower right corner of the sedimentation tank body 1, and after the sedimentation is accumulated between the sedimentation tank body 1 and the sewage hopper 16, the drainage outlet of the equipment can be opened, and the precipitated wastewater will be discharged to the next level process, and the precipitated waste residue will be discharged outward through the internal spiral of the spiral conveying bin 17, and the degreasing, precipitation and purification operation of the entire grease-containing wastewater can be completed. In addition, since the movable push plate 9 will move toward the upper left of the sedimentation tank body 1 with multiple heating rods 13 when it moves back and forth horizontally, while the chemical agents are concentrated and fall to the upper left area, the movable heating structure composed of the limiting ribs 11, the wiring sleeve 12 and the heating rod 13 will heat the grease solidified into lumps, so that it can better react and dissolve with the chemical agents after heating and decomposition.
