Description

Device for removing swarf of strip grinding line {Device for removing swarf in strip grinding line}

The present invention relates to a swap processing facility for separating the swarf generated during the strip grinding operation in the strip grinding line from the abrasive oil.

In general, the coil subjected to annealing is subjected to a polishing line to remove defects on the surface of the strip, which is then sent to the next process, which is performed by strip grinders arranged along the line. The generated swarf is sent to the swarf processing facility through a chute installed at the bottom of the grinder.

The swarf generated during strip polishing is a mixture of coolant abrasive oil used for polishing and fine chips polished from the strip, and then aggregated together in a cotton form. The swarf sent to the swarf processing facility is provided with a screen and a filter. Each chip can be separated and reused.

As shown in FIG. 5, the swap processing facility includes a swarf conveyor tank 101 for firstly filtering swarf discharged from the chute 100 and abrasive oil, and a fine swarf connected to the conveyor tank 101. A filter tank 103 equipped with a filter 102 to separate the abrasive oil, and a clean tank 104 for storing the abrasive oil filtered from the filter tank 103.

Therefore, the swarf and coolant abrasive oil generated during the strip grinding are discharged to the swap conveyor tank 101 through the chute 100 and are first filtered while passing through the base screen (not shown) installed in the tank 101. Fine swarf and abrasive oil are sent to filter tank 103 where abrasive oil is separated through filter 102 where abrasive oil is sent to clean tank 104 and fine swarf is reprocessed through a bottom conveyor 105. Sent to the process.

The filter is composed of a case of a rectangular frame and a filter network covered by the case so as to achieve a predetermined width so as to filter the swarf from the abrasive oil and suck out only the clean oil to the clean tank.

However, the conventional swarf treatment equipment has a lot of abrasive oil loss, and the conveyor is used to transfer the swarf to the centrifuge, causing frequent failures due to the overload of the conveyor driving motor and delayed swap processing time.

Accordingly, the present invention has been made in order to solve the above problems, it is easy to collect the swarf by treating the filter vertically arranged to provide a swap removal equipment of the strip grinding line that can increase the removal efficiency of the abrasive oil. There is this.

Hereinafter will be described the operation of the present invention.

The abrasive oil used in the strip grinding operation flows into the chute 100 installed under each cabin and flows into the filter tank 10 through the upper side of the filter tank 10.

When the abrasive oil flows into the filter tank 10, the suction fan 42 is operated to filter the swarf from the abrasive oil through the filter 23 and discharge the filtered abrasive oil to the storage tank 40.

As the abrasive oil proceeds from the top of the filter tank 10 to the bottom, the swarf included in the abrasive oil is filtered out by the filter 23 installed in the filter head 20, and the abrasive oil passes through the filter 23 to the storage tank ( 40).

That is, during the operation of transferring the abrasive oil to the storage tank 40 normally, the first solenoid valve 45 of the solenoid valves 45 and 46 installed in the discharge pipe 41 is opened and the second solenoid valve 46 is operated. Is closed, the third solenoid valve 47 of the solenoid valves 47 and 48 installed in the inlet pipe 43 is closed and the fourth solenoid valve 48 is opened.

As described above, when the suction fan 42 is driven while the solenoid valves 45, 46, 47, and 48 are opened and closed, the abrasive oil, in which the swarf is removed while passing through the filter 23, is disposed inside the filter 23. The storage tank 40 is introduced into the filter head 20 through the hole of the filter pipe 30 and through the suction pipe 43 through the discharge pipe 41 connected to the discharge pipe 24 by the suction fan 42. Is transferred to).

Thus, the abrasive oil is continuously filtered through the filter 23 arranged up and down of the filter tank 10, and the abrasive oil is reversed during the cleaning operation of the filter 23 for removing the swarf attached to the filter 23. In this case, the solenoid valves 45, 46, 47, and 48 are operated in reverse to switch the open / close state.

Therefore, the abrasive oil contained in the storage tank 40 is sucked into the suction fan 42 through the discharge pipe 41 and passes through the branch pipe 44 connected to the outlet side of the suction fan 42. Out through the inlet tube 25 through the hole of the filter tube 30 installed in the filter head 20 is to drop off the swap attached to the filter (23).

As described above, as the abrasive oil injected into the upper portion of the filter tank 10 passes through the plurality of filters 23 arranged vertically, the swarf is sequentially filtered to maximize separation of the swarf and the abrasive oil.

On the other hand, the remaining swarf after the abrasive oil is removed sinks to the bottom in the filter tank 10, the sunk swarf is introduced into the moving tube 60 connected to the hopper 12 of the bottom of the filter tank 10 and the moving tube 60 In accordance with the operation of the drive motor 62 is installed in the) is sent to the end of the moving tube 60 along the rotating screw (61).

The swarf transferred to the end of the moving tube 60 is introduced into the vertical tube 63, and when the vertical motor 64 installed on the vertical tube 63 is operated, the transfer blade 66 installed on the vertical shaft 65 rotates. While pulling the swarf introduced into the vertical pipe (63) to the upper vertical pipe (63).

The swarf pulled upwards of the vertical tube 63 enters the input tube 67 and is also transferred to the end of the input tube 67 by the driving motor 69 and the transfer screw 68, and thus the lower end of the input tube 67. Into the centrifuge (70) located in will be reprocessed.

According to the swarf removal equipment of the strip grinding line according to the present invention as described above, it is possible to use the abrasive oil in a clean state by the efficient separation of the swarf contained in the abrasive oil, There is an effect to prevent overload.
