Description

Technical Field

[0001] This utility model belongs to the field of belt skimmers, specifically a pre-tightening device for belt skimmers. Background Technology

[0002] A belt skimmer is a device used to remove floating oil from the surface of a liquid. It scrapes the floating oil from the water or liquid surface through a drive belt and is commonly used in industrial oil-water separation, cutting fluid management and other scenarios. The belt skimmer is mainly composed of a drive belt driven by a motor. The belt is immersed in the liquid and transfers the floating oil to the surface of the water through physical scraping or adsorption, and then it is removed by a scraper.

[0003] Currently, there are many types of emulsion skimmers in cold rolling equipment, among which belt skimmers are widely used. During the long-term use of belt skimmers, the skimmer belt and belt roller often slip and spin, affecting the emulsion skimming effect. In summary, this utility model provides a pre-tightening device for a belt skimmer to solve the above-mentioned problems. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a pre-tightening device for a belt skimmer, which solves the problem in the prior art where the skimmer belt and belt roller frequently slip and spin idly, affecting the skimming effect of the emulsion.

[0005] A pre-tightening device for a belt skimmer includes a frame on which a belt roller and a positioning roller are mounted. The positioning roller and the belt roller are connected by a skimmer belt. A belt pressure roller is positioned above the belt roller. Both ends of the belt pressure roller are rotatably connected to pressure roller guide plates via drive shafts. The pressure roller guide plates are slidably connected to the top of the frame via guide slides. Linkage slide plates are slidably connected to the adjacent sides of the pressure roller guide plates. Linkage shafts are respectively provided on both sides of the linkage slide plates. A drive gear is fixedly sleeved in the middle of the linkage shaft. Linkage gears are fixedly connected to both ends of the linkage shaft. A drive gear plate is provided between the drive gears. One end of the drive gear plate is connected to the top of the frame via a hydraulic push rod. Multiple tooth grooves are respectively opened on both sides of the linkage slide plates, and the linkage gears mesh with the tooth grooves.

[0006] Furthermore, a slide groove is provided on one side of the pressure roller guide plate that is close to each other, and one side of the linkage slide plate is slidably connected in the slide groove. Both ends of the linkage slide plate are respectively connected in the slide groove by a return spring.

[0007] Furthermore, one side of the linkage slide plate passes through the slide plate groove and protrudes from the surface of the pressure roller guide plate, and the toothed grooves are equidistantly arranged along the vertical direction of the linkage slide plate.

[0008] Furthermore, the drive tooth plate is disposed on the top of the belt pressure roller, and the drive tooth plate meshes with the drive gear.

[0009] Furthermore, the guide slide is slidably sleeved on the surface of the pressure roller guide plate, and one end of the guide slide is fixedly connected to the bottom of the frame.

[0010] Furthermore, a linkage shaft bracket is provided on the linkage shaft, the linkage shaft movably passes through one end of the linkage shaft bracket, and the linkage shaft bracket is vertically connected to the bottom of the frame.

[0011] Furthermore, the belt pressure roller is in contact with the surface of the skimming belt, and the surface of the belt pressure roller is provided with anti-slip grooves.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model increases the friction between the oil skimmer and the belt by adding a belt pressure roller to the belt skimmer, thereby preventing slippage and idling. At the same time, the surface of the belt pressure roller is provided with anti-slip grooves, which further enhances the gripping force between the belt and the oil skimmer, ensuring the stability of the equipment operation.

[0013] 2. This utility model, through the cooperation of hydraulic push rod and drive tooth plate, can flexibly adjust the pressure of belt pressure roller according to actual needs, thereby adapting to the operating requirements under different working conditions; the meshing design of linkage gear and tooth groove makes the transmission of the whole device more precise and reliable. When adjusting the horizontal height of belt pressure roller, both ends of belt pressure roller can be raised and lowered at the same time, and the frequency of adjustment on both sides is the same.

[0014] 3. The present invention ensures that the linkage slide plate automatically presses against the surface of the belt roller in the working state by setting a reset spring, which increases the flexibility between the pressing structure and the belt roller, and uses hydraulic push rods for synchronous adjustment.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figure 1-5 As shown, this utility model provides a pre-tightening device for a belt skimmer, including a frame 1. A belt roller 4 and a positioning roller 3 are installed on the frame 1. The positioning roller 3 and the belt roller 4 are connected by a skimmer belt 2. A belt pressure roller 5 is arranged above the belt roller 4. The two ends of the belt pressure roller 5 are rotatably connected to pressure roller guide plates 7 through a drive shaft. The pressure roller guide plates 7 are slidably connected to the top of the frame 1 through a guide slide 6. A linkage slide plate 12 is slidably connected to the adjacent side surfaces of the pressure roller guide plates 7. A linkage shaft 9 is arranged on both sides of the linkage slide plate 12. A drive gear 16 is fixedly sleeved in the middle of the linkage shaft 9. A linkage gear 15 is fixedly connected to both ends of the linkage shaft 9. A drive tooth plate 11 is arranged between the drive gears 16. One end of the drive tooth plate 11 is connected to the top of the frame 1 through a hydraulic push rod 10. Multiple tooth grooves are opened on both sides of the linkage slide plate 12. The linkage gear 15 meshes with the tooth grooves.

[0019] As one embodiment of this utility model, a slide groove 13 is provided on one side of the pressure roller guide plate 7 that is close to each other. One side of the linkage slide plate 12 is slidably connected in the slide groove 13, and the two ends of the linkage slide plate 12 are respectively connected in the slide groove 13 by a reset spring 14.

[0020] As one embodiment of this utility model, one side of the linkage slide plate 12 passes through the slide plate groove 13 and protrudes from the surface of the pressure roller guide plate 7, and the tooth grooves are equidistantly arranged along the vertical direction of the linkage slide plate 12.

[0021] In one embodiment of this utility model, the drive tooth plate 11 is disposed on the top of the belt pressure roller 5, and the drive tooth plate 11 meshes with the drive gear 16.

[0022] In one embodiment of this utility model, the guide slide 6 is slidably sleeved on the surface of the pressure roller guide plate 7, and one end of the guide slide 6 is fixedly connected to the bottom of the frame 1.

[0023] As one embodiment of this utility model, a linkage shaft bracket 8 is provided on the linkage shaft 9, the linkage shaft 9 movably passes through one end of the linkage shaft bracket 8, and the linkage shaft bracket 8 is vertically connected to the bottom of the frame 1.

[0024] In one embodiment of this utility model, the belt pressure roller 5 is in contact with the surface of the skimmed belt 2, and the surface of the belt pressure roller 5 is provided with anti-slip grooves.

[0025] Specific working principle: Start the hydraulic push rod 10. The hydraulic push rod 10 moves the drive gear plate 11 up and down. The movement of the drive gear plate 11 drives the drive gear 16 to rotate. Since the drive gear 16 is fixedly sleeved on the linkage shaft 9, the linkage shaft 9 rotates accordingly, thereby driving the linkage gear 15 to rotate. The linkage gear 15 meshes with the toothed groove on the linkage slide plate 12, so the rotation of the linkage gear 15 will push the linkage slide plate 12 to slide horizontally along the slide plate groove 13. The return spring 14 is stretched or compressed when the linkage slide plate 12 slides, ensuring that the linkage slide plate 12 can automatically abut against the required position, while providing a certain cushioning effect.

[0026] When the hydraulic push rod 10 adjusts the height of the drive toothed plate 11, the tooth grooves on both sides of the linkage slide plate 12 and the linkage gear 15 always remain engaged, making the movement of the linkage slide plate 12 smoother and more synchronized. This design ensures that the lifting amplitude of both ends of the belt pressure roller 5 is consistent, avoiding tilting or jamming caused by uneven force, thereby improving the reliability of equipment operation.

[0027] Furthermore, the guide slide 6 ensures the stability of the sliding trajectory of the pressure roller guide plate 7 on the frame 1, preventing deviation due to external interference. The linkage shaft bracket 8 provides a stable support point for the linkage shaft 9, enabling it to maintain precise positioning performance during high-speed operation. The entire device achieves precise control of the pressure and position of the belt pressure roller 5 through the coordinated operation of the hydraulic push rod 10, drive toothed plate 11, linkage gear 15, and tooth groove, meeting the operational requirements under different working conditions.
