Description

Technical Field

[0001] The utility model relates to the technical field of pickling, in particular to a device for pickling milling cutter blanks. Background Art

[0002] At present, when the milling cutter blank pickling device is pickling, the commonly used pickling method is to directly immerse the blank in acid solution. The public (announcement) number is: CN220450305U. In order to reduce the amount of acid solution, the spray pickling method is adopted. The acid solution after pickling is filtered through the filter plate to filter impurities. The filtered acid solution is then re-transported to the acid solution tank through the return pipe to achieve recycling.

[0003] In the above scheme, since the pickling time of the milling cutter blank is generally 10-15 minutes, a long time of flushing is required, and the energy consumption will be relatively large. Therefore, this scheme provides a milling cutter blank pickling device, which combines spray pickling and immersion pickling, which can reduce the amount of acid used and effectively reduce energy consumption.

[0006] Preferred technical solution one: the space enclosed by the filter plate and the fan-shaped groove is greater than or equal to the capacity of the pickling tank, and the diameter of the mesh hole on the filter plate is smaller than the diameter of the fan-shaped flow hole, so that when the fan-shaped groove rotates to just below the fan-shaped flow hole, the acid in the pickling tank will be quickly discharged from the pickling tank to the fan-shaped groove for slow filtration.

When the filter plate is filtering, the drain pipe moves to the bottom of the filter plate, and the drain pipe is connected with the liquid tank. When the filter plate needs to be cleaned, the annular seat two is rotated to move the backwash cleaning pipe to the bottom of the filter plate, and the backwash cleaning pipe is connected with the liquid tank, and the filter plate is backwashed from the bottom by the acid sprayed from the backwash cleaning pipe to clear the blockage of the filter plate.

[0008] Preferred technical solution three: an annular movable cover is rotatably provided on the top wall of the liquid tank, and the bottom ends of the drain pipe and the backwash cleaning pipe penetrate the annular movable cover and extend into the liquid tank.

[0009] Preferred technical solution four: the nozzle arranged on the pickling tank is connected to the liquid tank via a pipeline.

[0010] Preferred technical solution five: A collecting box is provided on the outer wall of the device shell, and when the filter plate is flushed by the backwash cleaning pipe, the flushed sewage is collected in the collecting box.

[0011] Preferred technical solution six: the filter plate is in an inclined setting, that is, the top end of the filter plate is close to the center of the annular seat, and the lower end of the filter plate is close to the collection box.

[0012] The above structure enables this solution to have the following beneficial effects:

[0013] 1. Combining the spray pickling method with the immersion pickling method can reduce the amount of acid and effectively reduce energy consumption;

[0014] 2. To solve the problem that the existing filter plate lacks a cleaning structure and is prone to clogging, the filter plate is backwashed and cleaned through the backwash cleaning pipe to ensure the continuity of the filter plate's operation. BRIEF DESCRIPTION OF THE DRAWINGS
