Description

Technical Field

[0001] This utility model relates to the field of SCR continuous casting and rolling production technology, and in particular to an integrated device for filter cloth backwashing and winding and copper powder recovery. Background Technology

[0002] In the rolling stage of the SCR continuous casting and rolling production line, the emulsion is used as a high-pressure rinsing and descaling medium for the billet and as a cooling medium, during which a large amount of copper powder is shed. The emulsion is recycled in the production process, and during the return flow, it needs to be finely filtered by a filter. The filter effectively adsorbs the copper powder onto the filter cloth through the interaction between the filter cloth and the emulsion, and then collects it into a waste filter cloth box. However, fine copper powder cannot be completely filtered out, causing it to adhere to the surface of the rolls and be rolled along with the copper rod during subsequent recycling, thus affecting the subsequent wire drawing effect. Before treating the waste filter cloth as solid waste, the copper powder on the filter cloth needs to be manually cleaned, which not only increases the workload but also has limited cleaning effect. To address this problem, the branch company has carefully developed an integrated equipment for filter cloth backwashing and winding and copper powder recovery, aiming to improve the service life of the filter cloth and the copper powder recovery efficiency, while reducing the amount of manual cleaning.

[0023] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0024] like Figure 1-5 As shown, an integrated device for filter cloth backwashing and winding and copper powder recovery includes a machine body, a screw conveying mechanism, a filter cloth winding mechanism and a backwashing mechanism.

[0025] The machine body includes a base frame 1 and a left side plate 2 and a right side plate 3 located on the upper left and right sides of the base frame 1. A pad plate 4 with a front-low and rear-high inclined distribution is fixedly connected to the upper side between the left side plate 2 and the right side plate 3. A scraper 5 is fixedly connected to the upper side of the pad plate 4. An inclined groove plate 6 is provided in the middle between the left side plate 2 and the right side plate 3. A support plate 7 is provided on the front side of both the left side plate 2 and the right side plate 3. A filter cloth winding mechanism is provided on the upper side of the base frame 1.

[0026] A screw conveyor mechanism is provided above the pallet 7. The screw conveyor mechanism includes a conveying cylinder 8, a screw 9, and a motor. The conveying cylinder 8 is provided on the upper side of the pallet 7. The upper side of the conveying cylinder 8 has an elongated hole 10 that runs through the inside and outside. The elongated hole 10 is located below the scraper 5. The left end of the conveying cylinder 8 extends to the left side of the left side plate 2. The lower outer side of the left end of the conveying cylinder 8 has an outlet 11 that runs through the inside and outside. The screw 9 is provided inside the conveying cylinder 8. The right end of the conveying cylinder 8 has a motor. The output shaft of the motor is fixedly connected to the screw 9.

[0027] A backwashing mechanism is provided at the upper middle position between the left side plate 2 and the right side plate 3. The backwashing mechanism includes a water spray pipe 12 and a high-pressure nozzle 13. A water spray pipe 12 is provided between the left side plate 2 and the right side plate 3 above the inclined trough plate 6. Multiple high-pressure nozzles 13 are installed on the water spray pipe 12.

[0028] Among them, the pad plate 4 is used for the installation of the scraper 5; the inclined trough plate 6 is used for the recovery of emulsion and copper powder after rinsing; the support plate 7 is used for the installation and fixing of the conveying cylinder 8; the screw conveying mechanism drives the screw 9 to rotate inside the conveying cylinder 8 through the motor. After the scraper 5 scrapes the copper powder off the filter cloth, it enters the inner side of the conveying cylinder 8 through the elongated hole 10 on the conveying cylinder 8, and then the rotating screw 9 outputs the copper powder.

[0029] When the backwashing mechanism is working, the emulsion is introduced into the spray pipe 12 through the external water pipe by connecting the spray pipe 12 to the external water pipe. It is then sprayed out by the high-pressure nozzle 13 to rinse the filter cloth, clean the copper powder remaining on the filter cloth, and facilitate the collection of copper powder and the cleaning of the filter cloth.

[0030] like Figure 1-5 As shown, the filter cloth winding mechanism includes a first rotating roller 14, a second rotating roller 15, a third rotating roller 16, a fourth rotating roller 17, a tension bar 18, a winding shaft 19, a bearing seat, and a winding rod 20. The first rotating roller 14 is located on the upper rear side between the left side plate 2 and the right side plate 3, and the second rotating roller 15 is located on the upper front side between the left side plate 2 and the right side plate 3. The second rotating roller 15 is located on the upper side of the pad plate 4. The third rotating roller 16 is located between the left side plate 2 and the right side plate 3 above the inclined plate groove, and the fourth rotating roller 17 is located at the bottom between the left side plate 2 and the right side plate 3 below the third rotating roller 16. The tension bar 18 is located on the bottom front side between the left side plate 2 and the right side plate 3.

[0031] Bearing seats are provided on both the left and right sides of the upper part of the bottom frame 1 at the front side of the left side plate 2. Bearings are installed on the bearing seats. The two bearings on the left and right sides are fitted with a winding shaft 19. Multiple winding rods 20 are fixedly installed on the outside of the winding shaft 19 located between the two bearing seats.

[0032] The first rotating roller 14, the second rotating roller 15, the third rotating roller 16, and the fourth rotating roller 17 are all connected to the machine body through bearings for easy rotation. During operation, the winding shaft 19 is connected to an external geared motor, which drives the winding shaft 19 to rotate, thereby further driving the winding rod 20 to rotate and winding the filter cloth.

[0033] like Figure 2 , 5 As shown, a fixing plate 21 is fixedly fitted on the outer side of one end of the take-up shaft 19 near the inner side of the bearing seat. The fixing plate 21 has multiple slots with outward openings along the radial direction. The number of slots is the same as the number of take-up rods 20. Each take-up rod 20 is provided with a locking block 22 that matches the slot. The side of the locking block 22 away from the take-up rod 20 is located inside the corresponding slot. A cover plate 23 is fitted on the outer side of the fixing plate 21.

[0034] The cover plate 23 is used to fix the locking block 22 in the slot, so as to prevent the locking block 22 from falling out of the slot and affecting the rotation effect of the winding shaft 19 driving the winding rod 20. This achieves the purpose of fixing the winding rod 20 and the winding shaft 19 together.

[0035] like Figure 5 As shown, the bearing housing includes an upper clamp 24, a lower clamp 25, and a fixing bolt 26. The lower clamp 25 is fixedly connected to the upper part of the bottom frame 1. The upper clamp 24 is hinged to one side of the upper part of the lower clamp 25. The other side of the lower clamp 25 is connected to the upper clamp 24 at the corresponding position by the fixing bolt 26. The bearing is installed between the upper clamp 24 and the lower clamp 25 at the corresponding position. A copper sleeve 27 is fixedly fitted inside the bearing. The winding shaft 19 is fixedly connected to the copper sleeve 27 at the corresponding position.

[0036] In use, the upper clamp 24 can be lifted by removing the fixing bolt 26, which facilitates the installation of the bearing located in the bearing housing, the copper sleeve 27 located in the bearing, and the winding shaft 19. After installation, the upper clamp 24 is lowered, and the upper clamp 24 and the lower clamp 25 are fixed together by the fixing bolt 26, thereby achieving the effect of fixing the winding shaft 19.

[0037] like Figure 1-4As shown, an opening is provided on the left side plate 2 corresponding to the position of the inclined chute plate 6. The left side of the inclined chute plate 6 passes through the opening and is located on the left side of the left side plate 2. A water tank is provided at the left outlet 11 of the inclined chute plate 6. Thus, during operation, the emulsion and copper powder inside the inclined chute plate 6 flow out into the water tank. The water tank is provided with a shelf with an upper opening. During the flow in the water tank, the copper powder in the emulsion will settle at the bottom of the water tank, and the copper powder can be recycled secondaryly using the water tank.

[0038] like Figure 2 As shown, it also includes a retaining ring 28. Mounting holes are provided on the left side plate 2 and right side plate 3 corresponding to the position of the water spray pipe 12. A retaining ring 28 is installed in each mounting hole, and the water spray pipe 12 is fitted into the retaining ring 28 at the corresponding position. This facilitates the fixing of the water spray pipe 12 to the machine body.

[0039] The working process of this utility model is as follows:

[0040] First, the filter cloth is wound around the top of the first rotating roller 14 and the second rotating roller 15, then wound into the gap between the second rotating roller 15 and the scraper 5, and after passing over the third rotating roller 16 and the fourth rotating roller 17, it is wound out from below the tension bar 18 and onto the take-up bar 20. When the filter cloth inside the external filter is conveyed outward, the tension bar 18 detects the tension change, and the reduction motor drives the take-up shaft 19 to rotate, thereby driving the take-up bar 20 to rotate and take up the filter cloth. As the filter cloth moves, it first passes through the scraper 5, which scrapes off the copper powder adhering to the filter cloth and into the conveying cylinder 8. At the same time, the copper powder adhering to the filter cloth is also scraped off by the scraper 5 and enters the conveying cylinder 8. Under the action of the motor, the screw 9 rotates synchronously with the winding shaft 19, pushing the copper powder in the conveying cylinder 8 along the spiral line of the screw 9 to the front outlet 11 for discharge. An iron bucket is placed at the outlet 11 of the conveying cylinder 8 to collect the copper powder. When the filter cloth moves further, the high-pressure nozzle 13 on the water spray pipe 12 will spray emulsion to rinse the filter cloth a second time. The copper powder washed off is discharged with the emulsion from the inclined plate 6 to the inside of the water tank at the outlet 11 of the inclined plate 6. The water tank is equipped with a shelf with an open top. During the flow in the water tank, the copper powder in the emulsion will settle at the bottom of the water tank, and the water tank can be used for secondary recovery of the copper powder.

[0041] In summary, this utility model has a simple structure and is easy to use. By setting up a spiral conveying mechanism and a backwashing mechanism, the copper powder on the filter cloth is scraped into the spiral conveying mechanism by the scraper 5. The spiral conveying mechanism transports the copper powder to achieve primary cleaning of the filter cloth. After cleaning, the filter cloth is rinsed by the backwashing mechanism for secondary cleaning. The device has a high degree of automation, improves the copper powder recovery rate, and the rinsed filter cloth can be reused, which improves the working efficiency of the device and reduces the labor intensity of the workers.
