Description

Technical Field

[0001] The present invention relates to the technical field of roll production, and particularly relates to a dust-proof system for roll grinding. Background Art

[0002] A roll is the main working component and tool on a rolling mill that causes continuous plastic deformation of metal. A roll mainly consists of a roll body, roll necks, and a shaft head. The roll body is the middle part of the roll that actually participates in rolling metal, and it has a smooth cylindrical or grooved surface. The roll necks are installed in bearings, and the rolling force is transmitted to the rolling mill stand through the bearing seats and the screw-down device. The drive-end shaft head is connected to the gear housing through a coupling shaft to transmit the rotational torque of the motor to the roll. The rolls can be arranged in the form of two-high, three-high, four-high, or multi-high in the rolling mill stand.

[0003] After a roll has been used for a certain period of time, in order to grind off the fatigue layer on the roll surface and obtain a certain convexity and roughness, the roll must be ground. Currently, generally, a roll grinder is used to grind the roll. During the process of grinding the roll by the roll grinder, when the grinding wheel grinds the roll, a large amount of metal dust generated on the roll surface will float into the air, which will cause serious harm to the body if inhaled by workers. Summary of the Invention

[0004] In view of this, the present invention provides a dust-proof system for roll grinding, which can not only grind the roll, but also prevent the metal dust generated during the grinding of the roll by the roll grinder from floating into the air and being inhaled by workers, thus causing damage to the workers.

[0005] To solve the above technical problems, the present invention provides a dust-proof system for roll grinding, including a dust-proof working box for placing a roll grinder and enabling the roll grinder to grind the roll therein. An air suction mechanism for absorbing the metal dust generated during the grinding of the roll is arranged in the dust-proof working box. A box door for allowing people to enter the dust-proof working box is provided on the dust-proof working box. An observation window is provided on one side of the dust-proof working box. Magnetic adsorption layers for adsorbing the metal dust in the gas inside the box are arranged on the two adjacent inner walls of the dust-proof working box.

[0006] Preferably, the air suction mechanism includes a first adsorption box and a second adsorption box for adsorbing the metal dust on one side of the roll. The first adsorption box can be adjusted up and down. A first adsorption port facing the roll is opened on the first adsorption box. The air suction mechanism further includes a filtering component for filtering the gas containing metal dust adsorbed by the first adsorption box and the second adsorption box. A centrifugal blower is arranged on one side of the filtering component. A first connecting pipe for communicating with the filtering component is arranged on the air outlet end of the centrifugal blower.

[0007] Preferably, the filtering assembly includes a bracket, on which a filtering box with a box opening is provided. A box cover is buckled on the box opening of the filtering box. The filtering box is provided with a second connecting pipe and a third connecting pipe at intervals, and the two connecting pipes are respectively communicated with the bottom of the first adsorption box. Inside the filtering box, first filter bags are respectively fixedly installed at the ends of the second connecting pipe and the third connecting pipe.

[0008] Preferably, a sealing gasket is provided on the side of the box cover facing the box opening of the filtering box to ensure the sealing performance of the filtering box.

[0009] Preferably, a bottom plate is provided on one side of the bracket. Fixing rods are symmetrically arranged at intervals on the bottom plate. A circular hole extending along the length direction of the fixing rod is provided on the upward side of the fixing rod. A movable rod is inserted into the circular hole. One end of the movable rod is fixedly connected with a support seat. Connecting plates are respectively fixedly connected to the corresponding sides of the first adsorption box. A fixing column is fixedly connected to the downward side of the connecting plate. A fixing hole for inserting the fixing column is provided on the side of the support seat. Electric cylinders for pushing the first adsorption box to move up and down are respectively provided on the bottom plate between the two fixing rods.

[0010] Preferably, a second adsorption port is provided on the second adsorption box. The first adsorption box and the second adsorption box are arranged in a staggered manner. The second adsorption box is arranged on the other side of the roll grinder through a 7-shaped mounting frame. A fourth connecting pipe is communicated with the side of the second adsorption box. One end of the fourth connecting pipe is communicated with the filtering box. A second filter bag is fixedly installed at the end of the fourth connecting pipe located inside the filtering box.

[0011] Preferably, a collection box for collecting metal dust is provided inside the bracket.

[0012] Preferably, a control console for controlling the operation of the roll grinder is provided on one side of the dust-proof working box.

[0013] The beneficial effects of the above technical solutions of the present invention are as follows: When it is necessary to grind the roll, the worker first installs the roll on the roll grinder, then closes the box door to make the dust-proof working box in a closed state, and then starts the centrifugal blower and the roll grinder through the control console. The centrifugal blower makes the first adsorption box and the second adsorption box adsorb the generated metal dust respectively through the first connecting pipe, the filtering box, the second connecting pipe, the third connecting pipe and the fourth connecting pipe. The gas containing metal dust after adsorption enters the filtering box and is dedusted through the first filter bag and the second filter bag, so that the metal dust remains in the first filter bag and the second filter bag, and the clean gas is discharged through the centrifugal blower. Furthermore, the metal dust will not be adsorbed into the body by the worker and cause damage to the worker. Description of the Drawings

[0025] Embodiment 1

[0026] As Figures 1-6 shown: The dust-proof system for roll grinding includes a dust-proof working box 3 for placing a roll grinder 1 and enabling the roll grinder 1 to grind a roll 2 therein. An air suction mechanism for absorbing metal dust generated during the grinding of the roll 2 is provided in the dust-proof working box 3. A box door 4 for allowing people to enter the dust-proof working box 3 is provided on the dust-proof working box 3. An observation window 5 is provided on one side of the dust-proof working box 3. Magnetic adsorption layers 6 for adsorbing metal dust in the gas inside the box are provided on two adjacent inner walls of the dust-proof working box 3. The magnetic adsorption layer 6 includes rectangular magnets (not shown in the figure) laid flat on the inner wall of the dust-proof working box 3. The thickness of the rectangular magnet is relatively thin, and a film is pasted on the outer side of the rectangular magnet to ensure that the magnetic force of the rectangular magnet will not weaken.

[0027] During the process of the roll grinder 1 grinding the roll 2, the air suction mechanism can adsorb most of the metal dust, and a very small part of the metal dust drifts into the dust-proof working box 3. Since the metal dust contains a large amount of iron elements, the magnetic adsorption layer 6 can adsorb the iron elements and further process the generated metal dust. And during the process of grinding the roll 2, after the worker installs the roll 2 on the roll grinder 1, the box door 4 is closed. At this time, the dust-proof working box 3 is in a closed state, and the worker operates the operation of the roll grinder 1 outside. Therefore, the generated metal dust will not drift outside, and thus the generated metal dust will not be inhaled by the worker into the body and affect the worker's body.

[0028] As Figure 2As shown in the figure, in this embodiment, the dust suction mechanism includes a first suction box 7 and a second suction box 8 for adsorbing metal dust on one side of the roll 2. The first suction box 7 can be adjusted up and down. A first suction port 9 facing the roll 2 is provided on the first suction box 7. It also includes a filter assembly for filtering the gas containing metal dust adsorbed by the first suction box 7 and the second suction box 8. A centrifugal blower 10 is provided on one side of the filter assembly, and a first connecting pipe 11 for communicating with the filter assembly is provided at the air outlet end of the centrifugal blower 10.

[0029] The first suction port 9 of the first suction box 7 faces the grinding position of the grinding wheel and the roll 2, so that the metal dust generated during the grinding of the roll 2 by the grinding wheel can be timely sucked away by the first suction box 7. The second suction box 8 plays an auxiliary adsorption role and can further adsorb the metal dust to achieve the maximum dust suction effect.

[0030] Furthermore, in combination with Figure 3 and referring to Figure 5 As shown in the figure, in this embodiment, the filter assembly includes a bracket 12. A filter box 13 with a box opening is provided on the bracket 12. A box cover 14 is buckled on the box opening of the filter box 13. Second connecting pipes 15 and third connecting pipes 16 are arranged at intervals on the filter box 13, and the two connecting pipes are respectively communicated and provided at the bottom of the first suction box 7. First filter bags 17 are fixedly installed at the ends of the second connecting pipe 15 and the third connecting pipe 16 inside the filter box 13.

[0031] The filter box 13 can filter the gas containing metal dust adsorbed by the first suction box 7. The filtered metal dust is located inside the first filter bag 17, and the filtered clean air is discharged through the first connecting pipe 11 and the centrifugal blower 10.

[0032] A sealing gasket (not shown in the figure) is provided on the side of the box cover 14 facing the box opening of the filter box 13 to ensure the sealing performance of the filter box 13.

[0033] A bottom plate 18 is provided on one side of the bracket 12. Fixed rods 19 are arranged symmetrically at intervals on the bottom plate 18. Circular holes extending along the length direction of the fixed rod 19 are provided on the upward side of the fixed rod 19. A movable rod 20 is inserted into the circular hole. One end of the movable rod 20 is fixedly connected with a support seat 21. Connecting plates 22 are respectively fixedly connected to the corresponding sides of the first suction box 7. Fixed columns 23 are fixedly connected to the downward side of the connecting plate 22. Fixing holes for inserting the fixed columns 23 are provided on the side of the support seat 21. Electric cylinders 24 for pushing the first suction box 7 to move up and down are respectively provided on the bottom plate 18 between the two fixed rods 19.

[0034] Due to the situation where the sizes of the rollers 2 are different, when grinding rollers 2 of different sizes, in order to ensure that the first adsorption port 9 of the first adsorption box 7 is always in the best adsorption position, the position of the first adsorption box 7 can be adjusted by the electric cylinder 24. In addition, by adopting the bottom plate 18, the fixed rod 19, the movable rod 20, the support seat 21, the connecting plate 22 and the fixed column 23, it is convenient for workers to install and remove the first adsorption box 7 for cleaning, and the structure is stable.

[0035] A second adsorption port 25 is formed on the second adsorption box 8. The first adsorption box 7 and the second adsorption box 8 are arranged in a staggered manner. The second adsorption box 8 is arranged on the other side of the roll grinder 1 through an L-shaped mounting frame 26. The number of the mounting frames 26 is two, and the two mounting frames 26 are symmetrically arranged. The mounting frame 26 includes a vertical rod fixedly connected longitudinally. One end of the vertical rod is vertically fixedly connected with a cross rod. A support block adapted to the outer side surface of the second adsorption box 8 is fixedly connected to the upward side surface of the cross rod to define the position of the second adsorption box 8. A fourth connecting pipe 27 is communicated and arranged on the side surface of the second adsorption box 8. One end of the fourth connecting pipe 27 is communicated and arranged on the filter box 13. A second filter bag 28 is fixedly installed at the end of the fourth connecting pipe 27 located inside the filter box 13.

[0036] Similarly, during the grinding process of the roller 2 by the second adsorption box 8, the metal dust floating to the other side of the roller 2 is adsorbed, and the adsorbed metal dust is filtered by the second filter bag 28.

[0037] As Figure 3 shown, when workers remove the first filter bag 17 and the second filter bag 28 to clean the metal dust inside, the metal dust can be directly poured into the collection box 29. A collection box 29 for collecting metal dust is arranged inside the support 12.

[0038] As Figure 1 shown, a control console 30 for controlling the operation of the roll grinder 1 is arranged on one side of the dust-proof work box 3.

[0039] It should be noted that the roll grinder is well-known to those skilled in the art and is prior art, so it will not be elaborated here. Secondly, how the control console controls the operation of the roll grinder and how to control the blower to start are both prior art, so they will not be elaborated here.

[0040] Working principle of the present invention: When it is necessary to grind the roll 2, the worker first installs the roll 2 on the roll grinder 1, then closes the box door 4 to make the dust-proof work box 3 in a closed state, and then starts the centrifugal blower 10 and the roll grinder 1 through the console 30. The centrifugal blower 10 enables the first adsorption box 7 and the second adsorption box 8 to adsorb the generated metal dust through the first connecting pipe 11, the filter box 13, the second connecting pipe 15, the third connecting pipe 16 and the fourth connecting pipe 27 respectively. The gas containing metal dust after adsorption enters the filter box 13 and is dust-removed through the first filter bag 17 and the second filter bag 28, so that the metal dust remains in the first filter bag 17 and the second filter bag 28, and the clean gas is discharged through the centrifugal blower 10. Thus, the metal dust will not be adsorbed by the worker into the body and cause damage to the worker.

[0041] Embodiment 2

[0042] The difference between Embodiment 2 and Embodiment 1 is that the mounting frame includes a vertical rod, one end of the vertical rod is vertically fixedly connected with a cross rod, and a cylinder is inclined and hinged on the upward side of the cross rod. The output end of the cylinder is hinged to the outer side of the second adsorption box, and the adsorption position of the second adsorption port in the second adsorption box can be adjusted through the cylinder.

[0043] In the present invention, unless otherwise clearly specified and defined, for example, it can be fixedly connected, can also be detachably connected, or integrated; it can be mechanically connected, can also be electrically connected; it can be directly connected, can also be indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0044] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
