Description

Technical Field

[0001] The utility model relates to the technical field of oil mist generators, in particular to an oil mist generating device for a cold rolling mill. Background Art

[0002] The working rolls and support roll bearing boxes of the aluminum cold rolling mill need to be lubricated by an oil mist generator during the rolling process.

[0003] The application number in the existing public technology is: CN202322203729.6. The temperature-adjustable cold rolling mill oil mist generator, when in use, first open the temperature adjustment box, and then the staff presses the pressing block. The movement of the pressing block compresses the limit spring and causes the limit column to push the block closer to the connecting seat. At this time, the block is no longer stuck in the slot, and then the connecting seat can be separated from the mounting seat by lifting the connecting seat up and down, thereby achieving the purpose of replacing a single heater, greatly reducing maintenance costs, and having strong practicality and worthy of promotion.

[0004] However, the above patent still has certain disadvantages when in use: although the incoming air can be heated by a heater, since there is no internal obstruction, the compressed gas will flow smoothly at high speed when entering, and the gas cannot absorb the heat in time. At this time, in order to ensure that the compressed gas can be smoothly heated to the required temperature, the number of heaters will be increased to ensure the temperature increase, so that the overall number of heaters used for heating is large, which increases the overall cost of use and makes the overall structure more complicated, which is not conducive to better production and use, and the overall use effect is not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0008] (II) Technical solution

[0009] In order to achieve the above advantages of simple structure, low application cost and adjustable retention time, the specific technical solutions adopted by the utility model are as follows:

[0010] An oil mist generating device for a cold rolling mill comprises an oil mist generator and a temperature control cylinder, wherein a temperature control cylinder is installed on one side surface of the oil mist generator, a plurality of groups of mounting grooves are evenly arranged on the inner surface of the temperature control cylinder, a sealing disk is clamped inside the mounting groove, a limiting flow cover is integrally formed in the middle of the surface of the sealing disk, a heating column is provided at the center of the limiting flow cover and in the middle of the temperature control cylinder, a threaded head is fixedly installed at the bottom of the heating column, and a sealing head is welded at the bottom of the threaded head.

[0017] Furthermore, a sealing door is rotatably connected to a surface of one side of the temperature control cylinder.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the utility model provides an oil mist generating device for a cold rolling mill, which has the following beneficial effects:

[0020] (1) The utility model adopts a sealing disk and a flow baffle, so that personnel can insert different numbers of sealing disks into the temperature control cylinder according to the different retention times of the compressed gas required. Since a flow limiting hood is provided at the bottom of the sealing disk, and the flow limiting hood is a structure with a larger top and a smaller bottom, the entry of the gas below is blocked, thereby slowing down the overall gas flow speed, thereby extending the retention time of the gas, so that the gas can fully absorb the heat generated by the heating column, thereby eliminating the need for a large number of heating columns, reducing the overall production cost, and having the advantages of low application cost and adjustable retention time.

In actual use, only a plurality of sealing disks, temperature sensors and heating columns are arranged inside the temperature control cylinder. The number of structures involved is relatively small, so that the production cost and application cost are low, and the installation and maintenance are more convenient. In case of subsequent damage, the heating column can be replaced by simply turning down the sealing head, which improves the convenience of maintenance and has the advantage of simple structure.

[0029] According to an embodiment of the utility model, an oil mist generating device for a cold rolling mill is provided.

[0030] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-3As shown, according to an embodiment of the utility model, an oil mist generating device for a cold rolling mill includes an oil mist generator 1 and a temperature control cylinder 2. The temperature control cylinder 2 is installed on the surface of one side of the oil mist generator 1. A plurality of mounting grooves 6 are evenly arranged on the inner surface of the temperature control cylinder 2. A sealing disk 5 is clamped in the inner position of the mounting groove 6. A limiting flow cover 7 is integrally formed in the middle position of the surface of the sealing disk 5. A heating column 4 is provided at the center of the limiting flow cover 7, and a threaded head 11 is fixedly installed at the bottom of the heating column 4. A sealing head 10 is welded at the bottom of the threaded head 11.

[0031] In one embodiment, a thread groove 12 for threaded connection with the thread head 11 is provided at the middle position of the bottom surface of the temperature control cylinder 2 .

[0032] In one embodiment, a temperature sensor 3 is installed at the middle position of the top of the temperature control tube 2 . The temperature sensor 3 is provided to detect the temperature inside the temperature control tube 2 .

[0033] In one embodiment, a controller 8 is installed on one side of the surface of the oil mist generator 1. The controller 8 is configured to control the structure inside the temperature control tube 2. Since the controller 8 is of various types and the application technology is mature, there is no need to elaborate on it, and personnel can make flexible choices according to their needs.

[0034] In one embodiment, an air inlet pipe 9 is installed at the bottom of one side surface of the temperature control tube 2. The air inlet pipe 9 is provided to introduce compressed gas for use.

[0035] In one embodiment, an air outlet pipe 13 is installed at the top position of the other side surface of the temperature control tube 2. The air outlet pipe 13 is configured to discharge the heated gas so that this part of the gas can enter the oil mist generator 1, thereby ensuring the lubrication effect of the oil mist generator 1 and further ensuring the application effect of the cold rolling mill.

[0036] In one embodiment, the flow limiting hood 7 is a structure that is larger at the top and smaller at the bottom. The flow limiting hood 7 is provided to reduce the space for gas discharge, thereby extending the retention time of the gas, so that the gas has sufficient time to absorb the heat generated by the heating column 4, thereby improving the overall heat transfer effect.

[0037] In one embodiment, a sealing door is rotatably connected to the surface of one side of the temperature control cylinder 2. The sealing door is provided to facilitate personnel to load and unload the sealing disk 5, and a sealing gasket is provided on its surface to ensure the sealing effect during sealing.

[0038] Working principle: In actual use, personnel can install the temperature control tube 2 on one side surface of the oil mist generator 1, and then connect its outlet pipe 13 to the oil mist generator 1. Then, personnel can insert different numbers of sealing disks 5 into the temperature control tube 2 according to the required retention time of the compressed gas. Since a flow limiting cover 7 is provided at the bottom of the sealing disk 5, and the flow limiting cover 7 is a structure with a larger top and a smaller bottom, the entry of the gas below is blocked, thereby slowing down the overall gas flow speed, thereby extending the retention time of the gas, so that the gas can fully absorb the heat generated by the heating column 4, and thus there is no need to set up a large number of heating columns 4, thereby reducing the overall production cost. Then, the gas that absorbs the heat can enter the oil mist generator 1 to ensure the lubrication effect and efficiency of the oil mist generator 1, and the overall structure can be composed of only the heating column 4 and the sealing disk 5, the structure is simpler, and it is convenient to produce and use. The device as a whole has the advantages of simple structure, low application cost, and adjustable retention time.
