Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device for a hot-rolled coil grinder. Background Art

[0002] Hot-rolled coil grinding machines are specialized machines used for surface finishing of hot-rolled steel plates (i.e., hot-rolled coils). During processing, hot-rolled coil grinding machines generate a large amount of wastewater, primarily from coolant, lubricant, metal debris, and other impurities from the grinding process.

[0003] Currently, wastewater generated by grinding machines is treated by setting up a wastewater collection tank (also known as a water collection tank) under or next to the grinder to temporarily store the wastewater generated during the grinding process. However, existing wastewater collection tanks generally only have the functions of collecting and discharging wastewater. The wastewater may also contain some metal debris or other impurities, which increases the difficulty of subsequent wastewater treatment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a sewage treatment device for a hot-rolled coil grinder, which can perform solid-liquid separation on the sewage generated by the hot-rolled coil grinder.

[0007] Furthermore, the blowing mechanism includes a support seat, an air pump and a connecting pipe. One side of the support seat is fixedly connected to one side of the outer wall of the waste slag box, and the other side of the support seat is fixedly connected to the outer wall of the air pump. The output end of the air pump is fixedly connected to the lower end of the connecting pipe, and the upper end of the connecting pipe is connected to the cleaning assembly.

[0008] Furthermore, the cleaning assembly includes an air blowing pipe and several air blowing heads. The air blowing pipe is arranged parallel to the auxiliary roller.

[0010] Furthermore, a sewage pipe is fixedly connected to a side of the water collecting tank away from the waste slag tank, and a valve is provided inside the sewage pipe.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This sewage treatment device for hot-rolled coil grinding machines can separate the sewage flowing from the sewage leakage port of the grinding machine body into solid and liquid by arranging a filtering mechanism in the water collecting chamber of the water collecting tank below the grinding machine body, thus saving subsequent separation steps.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figures 1-4 , a sewage treatment device for a hot-rolled coil grinder, comprising a water collecting tank 2 installed just below a plurality of sewage leakage outlets 101 of a grinder body 1, a water collecting chamber 201 being provided on the upper surface of the water collecting tank 2, the water collecting chamber 201 being matched and aligned with the plurality of sewage leakage outlets 101, an outer wall of one end of the water collecting tank 2 being fixedly connected to a waste slag box 3, a waste slag outlet 301 being provided on the side of the waste slag box 3 away from the water collecting tank 2, an upper end of the inner wall of the water collecting chamber 201 being connected to a filtering mechanism, the other end of the filtering mechanism being located above the waste slag outlet 301, a blowing mechanism being connected to one side of the outer wall of the waste slag box 3, an output end of the blowing mechanism being connected to a cleaning component, the other end of the cleaning component passing through the outer wall of the waste slag box 3 to the inside of the waste slag outlet 301, and an end of the cleaning component located in the waste slag outlet 301 being also located inside the filtering mechanism.

[0022] like Figures 1 to 4 As shown, when the sewage treatment device for a hot-rolled coil grinder in the utility model is used, first turn on the switches of the filtering mechanism and the blowing mechanism, and then use the hot-rolled coil grinder normally. The sewage generated by the hot-rolled coil grinder during operation will flow along the sewage outlet 101 to the water collecting chamber 201 of the water collecting box 2, and while flowing into the water collecting chamber 201, it will first fall on the filtering mechanism, and then the filtering mechanism will separate the solid and liquid of the sewage, and the liquid will continue to flow to the bottom of the water collecting chamber 201, and the solid impurities will follow the filtering mechanism to move to the waste slag box 3, and then fall into the waste slag box 3 by natural falling or under the action of the blowing mechanism and the cleaning component, and then take it out from the waste slag outlet 301, which is convenient, fast and easy to operate.

[0023] It should be noted here that the hot rolled coil grinder is an existing mature technology, so its detailed structure, connection method, etc. will not be described in detail.

[0024] like Figure 1-Figure 3As shown, the filtering mechanism includes a motor 5, an auxiliary roller 6, a conveyor mesh belt 10 and an active roller 13. The outer wall of the motor 5 is fixedly connected to one side of the outer wall of the water collecting box 2, the output shaft of the motor 5 is fixedly connected to one end of the active roller 13, the other end of the active roller 13 passes through the outer wall of the water collecting box 2 and is rotatably connected to the inner wall of the water collecting box 2 at the penetration point, the active roller 13 and the auxiliary roller 6 are arranged in parallel, the auxiliary roller 6 passes through the outer wall of the waste slag box 3, and the outer wall of the auxiliary roller 6 is rotatably connected to the inner wall of the waste slag box 3 at the penetration point, the conveyor mesh belt 10 is sleeved on the outside of the auxiliary roller 6 and the active roller 13, and the inner side wall of the conveyor mesh belt 10 is slidably connected to the outer walls of the auxiliary roller 6 and the active roller 13.

[0025] More specifically, when the hot-rolled coil grinder is started, the motor 5 is started. Once started, the output shaft of the motor 5 rotates with the active roller 13. The conveyor belt 10, constrained by the active roller 13 and the auxiliary roller 6, rotates along with the active roller 13. Therefore, when the wastewater on the hot-rolled coil grinder flows through the sewage outlet 101 into the water collection chamber 201, it first flows onto the surface of the conveyor belt 10. Because the conveyor belt 10 is a mesh, the liquid portion of the wastewater continues to flow below the water collection chamber 201, while the solid portion of the wastewater follows the conveyor belt 10 into the waste slag box 3. There, it will fall into the waste slag box 3 due to its own gravity or the action of the blowing mechanism and cleaning components, and then enter the next cycle.

[0026] like Figure 1-Figure 3 As shown, the blowing mechanism includes a support base 7, an air pump 8 and a connecting pipe 9. One side of the support base 7 is fixedly connected to one side of the outer wall of the waste slag box 3, and the other side of the support base 7 is fixedly connected to the outer wall of the air pump 8. The output end of the air pump 8 is fixedly connected to the lower end of the connecting pipe 9, and the upper end of the connecting pipe 9 is connected to the cleaning component.

[0027] More specifically, when it is necessary to process the waste residue on the surface of the conveyor mesh belt 10, it is only necessary to turn on the air pump 8. After the air pump 8 is started, the output end supplies air to the outside, and then this part of the gas will enter the connecting pipe 9, and then enter the inside of the cleaning component from the connecting pipe 9, so that the impurities that are stuck to the surface of the conveyor mesh belt 10 and cannot fall off naturally can be blown off.

[0028] like Figure 3 and Figure 4 As shown, the cleaning assembly includes an air blowing pipe 11 and several air blowing heads 12. The air blowing pipe 11 is arranged parallel to the auxiliary roller 6. The two ends of the air blowing pipe 11 respectively pass through the two sides of the waste slag box 3. The outer walls of the two ends of the air blowing pipe 11 are respectively fixedly connected to the inner walls of the waste slag box 3 at the penetration point, and one end of the air blowing pipe 11 is also fixedly connected to the end of the connecting pipe 9 away from the air pump 8. The side wall of the air blowing pipe 11 is fixedly connected to the upper ends of the several air blowing heads 12. The lower ends of the several air blowing heads 12 are all facing the waste slag box 3. The air blowing pipe 11 and the several air blowing heads 12 are all located inside the conveyor mesh belt 10.

[0029] More specifically, after the gas from the air pump 8 is introduced into the connecting pipe 9, this part of the gas will continue to move into the blowing pipe 11, and then be blown out from the several blowing heads 12. Because the blowing heads 12 are located inside the conveyor mesh belt 10, it is possible to "back-blow" the surface of the conveyor mesh belt 10, thereby achieving the purpose of cleaning impurities adhering to the surface of the conveyor mesh belt 10.

[0030] like Figure 1-Figure 3 As shown, the inner wall of the waste residue opening 301 is slidably connected to a drawing door 4 .

[0031] More specifically, by setting up a pull-out door 4, the waste residue outlet 301 can be blocked first during processing. After the processing is completed or the waste residue inside the waste residue box 3 reaches a certain level, the pull-out door 4 can be opened for unified treatment; and another collection box can be set inside the waste residue box 3, so that some residual sewage adhering to the solid impurities can be collected for a second time to avoid flowing out from the waste residue outlet 301 and polluting the environment.

[0032] like Figure 1 As shown, a sewage pipe 14 is fixedly connected to the side of the water collecting tank 2 away from the waste slag tank 3, and a valve is provided inside the sewage pipe 14.

[0033] More specifically, by providing the sewage pipe 14 and the valve, the sewage collected in the water collecting chamber 201 can be processed, for example, transported to an external sewage treatment tank.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
