[0027] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0028] like Figure 1-Figure 2 As shown, a cooling water filtration device for a continuous casting machine includes a water tank 1 connected to a cooling water pipeline of the continuous casting machine, a filter cartridge 2 rotatably connected to the water tank 1, a slag discharge plate 3 connected to the interior of the filter cartridge 2, and a flushing nozzle assembly 4 for flushing the top of the filter cartridge 2.
[0029] The cooling water filtering device of the continuous casting machine of the present invention further comprises a motor driving assembly for driving the filter cartridge 2 to rotate. The motor driving assembly comprises a motor 51, a driving pulley 52 fixedly arranged on the motor shaft of the motor 51, a driven pulley 53 coaxially fixedly arranged at one axial end of the filter cartridge 2, and a transmission belt 54 sleeved between the driving pulley 52 and the driven pulley 53.
[0030] like Figure 3 , Figure 4 As shown, a water inlet pipe 11 and a water outlet pipe 13 are connected on the water tank 1, wherein the water inlet pipe 11 is arranged at the upper part of the water tank 1, one end of the water inlet pipe 11 is connected to the cooling water pipeline, and the other end of the water inlet pipe 11 extends into the filter cartridge 2. In this embodiment, the water inlet pipe 11 includes an outer water inlet pipe 14 connected to the cooling water pipeline of the continuous casting machine, and the pipe section of the water inlet pipe 11 located inside the filter cartridge 2 is an inclined inner pipe 12 arranged obliquely, and the outlet end of the outer water inlet pipe 14 is connected to the inclined inner pipe 12 through an elbow, and the free end of the inclined inner pipe 12 is lower than the end of the inclined inner pipe 12 close to the inlet of the water inlet pipe 11, that is, the free end of the inclined inner pipe 12 is lower than the end of the inclined inner pipe 12 connected to the outer water inlet pipe 14. The free end of the inclined inner pipe 12 is closed. In this way, water storage and accumulation in the water inlet pipe can be avoided. A leaking hole 111 is provided at the bottom of the pipe section of the water inlet pipe 11 located inside the filter cartridge 2. The leaking hole 111 is a strip-shaped leaking hole. The axial direction of the leaking hole 111 is parallel to the axial direction of the pipe section of the water inlet pipe 11 located inside the filter cartridge 2. In this embodiment, the axial direction of the leaking hole 111 is parallel to the axial direction of the inclined inner tube 12, so that the cooling water entering from the water inlet pipe 11 can be quickly and accurately discharged to the filter cartridge 2 for filtration. The outlet pipe 13 is connected and arranged at the lower part of the water tank 1. After the cooling water flows out of the cooling water pipeline of the continuous casting machine, it is filtered by the filter cartridge 2, and the residues, impurities, etc. are retained on the filter cartridge 2. The filtered cooling water flows from the filter cartridge 2 into the water tank 1, and then is discharged into the cooling water pipeline through the outlet pipe 13 for subsequent reuse.
[0031] like Figure 1-Figure 3As shown, the axial direction of the filter cartridge 2 is horizontally arranged, a plurality of first filter holes 21 are arranged on the filter cartridge 2, the slag discharge plate 3 is located below the flushing nozzle assembly 4, the slag discharge plate 3 is inclinedly arranged, the high end of the slag discharge plate 3 is located inside the filter cartridge 2, and the low end of the slag discharge plate 3 extends to the outside of the filter cartridge 2. In this embodiment, a plurality of second filter holes 31 are provided in the plate section of the slag discharge plate 3 located inside the filter cartridge 2, the aperture of the second filter hole 31 is equal to or smaller than the aperture of the first filter hole 21, and the slag discharge plate 3 located outside the filter cartridge 2 is a smooth plate surface, that is, the slag discharge plate 3 located outside the filter cartridge 2 is not provided with a through hole. When the aperture of the second filter hole 31 is equal to or smaller than the aperture of the first filter hole 21, the residues on the slag discharge plate 3 can be prevented from falling into the filter cartridge 2, and the residues can be directly discharged from the inclined slag discharge plate 3 to be collected outside, avoiding the trouble of manual cleaning of the residues falling into the filter cartridge 2. In addition, the second filter hole 31 is provided on the slag discharge plate 3, which can prevent excessive water from being discharged into the external impurity collection container along with the residues and impurities. In one of the schemes, the axial direction of the projection of the slag discharge plate 3 on the horizontal plane is parallel to the axial direction of the filter cartridge 2. Furthermore, the axial direction of the projection of the slag discharge plate 3 on the horizontal plane coincides with the projection of the top of the filter cartridge 2 on the horizontal plane, which can further ensure that the residues filtered by the cooling water can smoothly fall onto the slag discharge plate 3 under the action of gravity and the nozzle after rotating with the filter cartridge 2 to the top of the slag discharge plate 3. The cross section of the slag discharge plate 3 perpendicular to the axial direction is a downwardly convex arc surface, which is convenient for gathering the residues at the bottom of the slag discharge plate 3. In this embodiment, the slag discharge plate 3 is located in the upper middle part of the filter cylinder 2, the inclined inner tube 12 is located in the lower part of the filter cylinder 2, and the slag discharge plate 3 is located above the inclined inner tube 12. The water flowing out of the inclined inner tube 12 directly impacts the slag discharge plate 3, thereby extending the service life of the slag discharge plate 3 to a certain extent.
[0032] The flushing nozzle assembly 4 is connected to the water tank 1 through a pipeline, and a water pump 6 is arranged on the pipeline between the flushing nozzle assembly 4 and the water tank 1. The flushing nozzle assembly 4 includes a main pipe 41, and a plurality of nozzles 42 arranged on the main pipe 41. The plurality of nozzles 42 are arranged along the axial direction of the main pipe 41, and the nozzles 42 are spaced from the top of the filter cartridge 2. The axial direction of the main pipe 41 is parallel to the axial direction of the filter cartridge 2, and the projection of the main pipe 41 on the horizontal plane falls within the projection range of the slag discharge plate 3 on the horizontal plane, so that the residue on the top of the filter cartridge 2 can be further ensured to be completely flushed onto the slag discharge plate 3 through the nozzle 42. Among them, the flushing nozzle assembly 4 also includes a water shield 43, which is arranged on the upper part of the flushing nozzle assembly 4, and the water shield 43 includes a horizontal top plate and inclined side plates arranged on both sides of the top plate in the width direction. The axial direction of the top plate is perpendicular to the width direction, and the axial direction of the top plate is parallel to the axial direction of the main pipe 41. The setting of the water shield 43 can prevent the water sprayed from the nozzle 42 to the top of the filter cartridge 2 from splashing everywhere.
[0033] During installation, the water inlet outer pipe 14 is fixedly connected to the upper part of the water tank 1 through a vertical support rod 71. A lower bracket 72 is fixedly installed on the upper part of the water tank 1, one side of the lower bracket 72 is suspended and extends into the filter cartridge 2, and is fixedly connected to the bottom of the slag discharge plate 3 to support the slag discharge plate 3. The pipeline arranged between the flushing nozzle assembly 4 and the water tank 1 is a water delivery pipe 8, and an upper bracket 73 is fixedly arranged on the upper part of the water tank 1, and the upper bracket 73 fixes the water delivery pipe 8 through a pipe clamp.
[0034] like Figure 1-Figure 4 As shown, when the utility model is in use: cooling water flows out of the cooling water pipeline of the continuous casting machine, enters the filter cartridge 2 through the water inlet pipe 11 and the water leakage hole 111, and after filtering by the filter cartridge 2, the residues, impurities, etc. are retained on the filter cartridge 2. The filter cartridge 2 rotates with the motor drive assembly, and the residues and impurities retained on the filter cartridge 2 rotate with the filter cartridge 2 to the top of the slag discharge plate, and then fall on the slag discharge plate 3 under the flushing of the nozzle 42 and the action of gravity. The nozzle 42 can flush the filter cartridge 2 continuously or intermittently, on the one hand, the residues and impurities can be flushed down to the slag discharge plate 3, and on the other hand, the residues and impurities can be prevented from clogging the drum. The filtered cooling water flows from the filter cartridge 2 into the water tank 1, and then discharged into the cooling water pipeline through the outlet pipe 13 for subsequent reuse. The residual impurities on the slag discharge plate 3 can flow to the outside of the filter cartridge 2 and be collected in an impurity collection container (not shown) under the scouring of the water flow of the nozzle 42 and the inclination of the slag discharge plate 3. In addition, the flushing nozzle assembly 4 is connected to the water tank 1 through a pipeline, which can make full use of the filtered water in the water tank 1 to flush the filter cartridge 2 without the need for any external water source, thereby making full use of the cooling water.
[0035] The utility model can rotate the residue impurities on the filter cartridge 2 to the top of the residue plate 3 through the combination of the rotating filter cartridge 2, the slag plate 3, and the flushing nozzle assembly 4, and then flush the residue impurities onto the residue plate 3 under the action of the nozzle 42, and automatically discharge the residue impurities outside the filter cartridge 2 and collect them in the impurity collection container under the action of the residue plate 3, replacing the manual cleaning and collection process of the residue, realizing the automation of timely collecting the residue impurities in the cooling water, and no longer needing to stop the machine for manual cleaning of the filter cartridge, thus saving manpower. At the same time, it ensures that the filter cartridge 2 can be cleaned at any time, is not easy to clog the filter hole, and ensures that the filtering effect of the filter cartridge 2 always maintains a better filtering effect.
[0036] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
