Description

Technical Field

[0001] The utility model belongs to the technical field of oil film treatment equipment, and particularly relates to a device for quickly removing oil film from a sewage pit. Background Art

[0002] During the production process of semiconductor factories, a large amount of sewage is produced. There is a layer of light floating oil film on the surface of the sewage. If it cannot be treated in time, the oil film will adsorb on the surface of the catalyst, thus affecting the sewage treatment speed. If the oil film is treated before sewage treatment, the entire water body needs to be filtered. Since the water body is huge, the filtration rate will be very slow, reducing the sewage treatment speed; at the same time, because semiconductor sewage contains weak acid or weak base, the materials used for filtration will be corroded by acid or base. Coupled with the large amount of sewage to be filtered, the corrosion speed will be very fast. The traditional method for removing oil film has a low rate and high cost, and the treatment effect is very unsatisfactory. Summary of the Utility Model

[0003] In view of this, the purpose of the utility model is to provide a device for quickly removing oil film from a sewage pit to solve the deficiencies in the prior art.

[0025] See Figure 1 As shown, in the preferred embodiment, the sewage sump rapid oil film removal device of the present utility model includes a float 1 and a suction pipe 2. The float 1 includes a columnar floating body, and the columnar floating body has an upper floating plate body 101 and a lower floating plate body 102. The upper floating plate body 101 and the lower floating plate body 102 are respectively provided with connection ports 103. The upper floating plate body 101 and the lower floating plate body 102, as well as between the upper floating plate body 101 and the lower floating plate body 102, are all hollow structures, enabling the float 1 to float on the water surface. The hollow structure between the upper floating plate body 101 and the lower floating plate body 102 is provided with a water inlet 104, and the water inlet 104 communicates with the connection port of the lower floating plate body 102. One end of the suction pipe 2 is rotatably connected to the float 1 through the connection port 103 of the lower floating plate body 102, and the other end is connected to an external water pump. The end of the suction pipe 2 rotatably connected to the float 1 is provided with a rotary pusher.

[0026] SeeFigure 2 , Figure 3 As shown in Figure 3 , the rotary pusher includes at least one set of branch suction pipes 201 that horizontally surround the outer wall of the end of the suction pipe 2. The branch suction pipe 201 has an upper end and a lower end. One set of branch suction pipes 201 includes at least one branch suction pipe 201. When the number of branch suction pipes 201 in the same set is greater than or equal to two, the upper ends and lower ends of the branch suction pipes 201 in the same set are respectively located on the same horizontal plane. A spiral driving force is generated by the branch suction pipes 201, causing the float 1 to rotate and sucking away the floating oil film on the surface of the sewage while rotating.

[0027] Furthermore, the branch suction pipe 201 is an arc-shaped pipe that bends downward. One set of branch suction pipes 201 includes three branch suction pipes 201. The connecting lines of the upper and lower ends of the three branch suction pipes 201 form an angle of 60° with each other. The "triangular" structure can increase the stability of the spiral driving force.

[0028] In a preferred solution, referring to the figure shown, the rotary pusher includes three sets of branch suction pipes 201 arranged in sequence from top to bottom, continuously providing a rotary driving force for the float 1. The stable rotation of the float 1 can accelerate the speed of the oil film flowing towards the water inlet 104 of the float 1.

[0029] Referring to Figure 4 , Figure 5 As shown in Figure 5 , the float 1 is cylindrical, and the upper floating plate body 101 and the lower floating plate body 102 are both circular. Correspondingly, the hollow structures of the upper and lower floating plates are both circular. The float 1 is designed with a hollow structure and can automatically find the water surface. A number of vertical plates 105 are arranged at equal intervals along the outer edges of the upper floating plate body 101 and the lower floating plate body 102. The water inlet 104 is formed between two adjacent vertical plates 105. It is easy to understand that the upper floating plate body 101 and the lower floating plate body 102 in this case can be conceptually replaced up and down.

[0030] The vertical plate 105 is a rectangular plate. The long side direction of the vertical plate 105 extends vertically, and the wide side direction of the vertical plate 105 extends radially along the upper floating plate body 101 or the lower floating plate body 102.

[0031] The suction pipe 2 includes a first long straight section 202, an arc section 203, and a second long straight section 204 connected in sequence.

[0032] Both the suction pipe 2 and the float 1 are made of polytetrafluoroethylene material, which is acid and alkali resistant and has good hardness.

[0033] After the water pump is started, water is sucked through the suction pipe 2. The branch suction pipe 201 on the suction pipe 2 changes the water flow direction, and the downward-slanting water flow gives the float 1 a downward force and a lateral force. The downward force will pull down the float 1, making the water inlet 104 of the float 1 basically flush with the water surface. The floating oil film on the water surface flows into the suction pipe 2 from the water inlet 104 of the float 1, and the three lateral forces in different directions drive the float 1 to rotate quickly and stably.

[0034] The above is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
