Description

Technical Field

[0001] The utility model relates to the technical field of rolling oil sludge solid-liquid separation equipment, in particular to a rolling oil sludge solid-liquid separation device. Background Art

[0002] In the stainless steel cold rolling process, a large amount of sludge will be produced after the rolling oil is filtered through the filter. After a long period of sedimentation, the sludge will generally form a high-concentration muddy solid waste. If the sludge is not separated from the solid and liquid, the filter will be seriously blocked and unable to work normally. Therefore, the solid-liquid separation operation of the rolling sludge is very important.

[0003] At present, in the treatment of rolling sludge, a large amount of rolling sludge is first left to stand for a period of time to allow the muddy solid waste in the rolling sludge to settle, and the rolling oil is placed on the upper layer of the muddy solid waste. Then, a liquid suction pipe and an oil suction pipe are used to pump out the rolling oil precipitated in the solid-liquid separation box, thereby completing the solid-liquid separation operation. However, when the existing solid-liquid separation device is working, the staff needs to frequently adjust the position of the opening of the oil suction pipe according to the depth of the rolling oil so that the oil suction pipe can fully pump out the rolling oil on the upper layer of the muddy solid waste. This is time-consuming and labor-intensive, and seriously reduces the solid-liquid separation efficiency of the rolling sludge in the sludge sedimentation box. Utility Model Content

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0034] like Figure 1 As shown, a solid-liquid separation device for rolling sludge includes: a mounting side plate 11, which is vertically arranged on one side of the sludge sedimentation box 1; a transmission screw 6, which is vertically arranged on the side wall of the mounting side plate 11, and the top of the transmission screw 6 is rotatably connected to the top of the mounting side plate 11, and the bottom is cooperated with the drive motor 8; a horizontally arranged lifting plate 3, which is threadedly installed on the transmission screw 6, so that when the transmission screw 6 rotates, the lifting plate 3 can move up and down; a suction device, which is arranged on the lifting plate 3 and is used to suck rolling oil.

[0035] like Figure 1 and Figure 3 As shown, the top of the transmission screw 6 is connected to the top of the mounting side plate 11 through the bearing seat 5.

[0036] like Figure 1 As shown, the suction equipment includes: a mounting base 10, which is arranged on one side of the bottom of the mounting side plate 11; a liquid extraction pump 9, which is arranged on the mounting base 10; a connecting hard pipe 7, one end of which is connected to the liquid extraction pump 9, and the other end of which is installed with a connecting hose 2; a liquid extraction hard pipe 4, which is vertically installed on the lifting plate 3, the top of which is connected to the connecting hose 2, and the bottom is arranged in the sludge sedimentation box 1.

[0037] like Figure 2As shown, the utility model also includes: a liquid extraction hood 12, which is arranged at the bottom of the liquid extraction hard tube 4, and its top liquid inlet is correspondingly connected to the liquid extraction hard tube 4; two mounting plates 13, which are respectively arranged on both sides of the top of the liquid extraction hood 12; two pressure sensors 14, which are respectively mounted on the two mounting plates 13, and the two pressure sensors 14 are connected to the start and stop control parts of the drive motor 8 and the liquid extraction pump 9; two support blocks 15, which are respectively arranged on the side walls of the liquid extraction hood 12, and are each provided with a guide through hole; two vertically arranged guide columns 17, which are respectively mounted on the guide through holes so as to be movable up and down by springs 16; two connecting blocks 18, which are respectively arranged at the bottom of the two guide columns 17; wherein the two guide columns 17 correspond to the two pressure sensors 14, respectively.

[0038] When the utility model is in use, the staff first turns on the driving motor 8, and the driving motor 8 drives the transmission screw 6 to rotate through the bearing seat 5, so that the lifting plate 3 engaged with the outer side of the transmission screw 6 through the threaded transmission hole moves downward in the vertical direction, and the lifting plate 3 drives the liquid extraction hard pipe 4 and the liquid extraction cover 12 to move downward until the liquid extraction cover 12 is immersed in the rolling oil inside the sludge sedimentation box 1, then stops the operation of the driving motor 8, and turns on the liquid extraction pump 9, the liquid extraction pump 9 sucks the rolling oil inside the sludge sedimentation box 1 through the connecting hard pipe 7, the connecting hose 2, the liquid extraction hard pipe 4 and the liquid extraction cover 12, and sends the rolling oil to the external rolling oil collecting device for unified collection, during the suction process of the liquid extraction pump 9, the driving motor 8 should also be slowly driven by the transmission screw 6 to rotate, so that the liquid extraction cover 12 can slowly move inside the sludge sedimentation box 1 until the rolling oil inside the sludge sedimentation box 1 is fully extracted.

[0039] Among them, when the liquid extraction hood 12 moves close to the surface of the muddy solid waste, the connecting blocks 18 arranged on both sides of the liquid extraction hood 12 will first contact the surface of the muddy solid waste, and as the liquid extraction hood 12 continues to move downward, the connecting blocks 18 will drive the guide column 17 to move upward until one end of the guide column 17 is against the pressure sensor 14. At this time, the pressure sensor 14 controls the drive motor 8 and the liquid extraction pump 9 to stop working, and then stops the liquid extraction pump 9 from sucking the rolling oil inside the sludge sedimentation box 1, and at this time, the rolling oil inside the sludge sedimentation box 1 is also fully sucked.
