Description

Technical Field

[0001] The utility model relates to the technical field of pickling equipment, in particular to a horizontal pickling device for rolling pickling. Background Art

[0002] During the processing of optical fiber preforms, the surface of the preforms is rough, and there are defects such as floating dust impurities and small bubbles. These defects will directly affect the strength of the optical fiber during the drawing process and affect the quality of optical fiber production. Therefore, after the optical fiber preforms are processed, they will be pickled to eliminate surface defects and ensure that the optical fiber drawing produces products with qualified strength. In the prior art, the pickling of preforms is mostly completed by pickling equipment. The preforms are placed in a pickling tank filled with circulating hydrofluoric acid for soaking and pickling, and the surface of the preforms is corroded and polished by hydrofluoric acid. However, during the soaking and pickling process, the preforms are left stationary, resulting in uneven pickling effects and long pickling time, and low pickling efficiency.

[0003] For example, Chinese patent announcement No. CN219950842U discloses a horizontal pickling device for rolling pickling. When in use, a pickling tank and a pickling basket vertically slidably installed in the pickling tank are provided, and multiple groups of rolling support assemblies are arranged in the pickling basket. During pickling, the pickling basket drives the rolling support assembly and the preform rods to be immersed in the pickling liquid. When the preform rods are pickled, the pickling basket is driven to move upward as a whole, and several rolling support assemblies and the preform rods are removed from the pickling liquid. The preform rods can be easily removed without discharging the pickling liquid. A blowing cavity and a blowing port are provided in the support roller and the mounting roller, and the blowing cavity is connected to the blowing assembly. The blowing assembly is used to blow air into the pickling liquid through the blowing cavity and the blowing port, so that during the pickling process of the preform rod rotating, the pickling liquid surges, and the impurities corroded on the preform rod are blown off, thereby ensuring the uniformity of the pickling liquid concentration and improving the pickling effect and pickling efficiency of the preform rod.

[0004] However, the horizontal pickling device for rolling pickling in the above application does not have a corresponding drying device after the pickling of the preform rods is completed. After the preform rods are taken out, they are more likely to absorb dust and need to be cleaned. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a horizontal pickling device for rolling pickling. Utility Model Content

[0006] The purpose of the utility model is to provide a horizontal pickling device for rolling pickling, so as to solve the problem that the horizontal pickling device for rolling pickling proposed in the above-mentioned background technology is not provided with a corresponding drying device after the pickling of the preform rod is completed. After the preform rod is taken out, it is easy to absorb and be contaminated with dust, and it needs to be cleaned.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a horizontal pickling device for rolling pickling, comprising a pickling tank and a sealed tank cover, wherein the sealed tank cover is hinged to the right side of the pickling tank, a drying device is arranged on the back of the pickling tank, and a pickling device is arranged inside the pickling tank.

The air supply pipe is fixedly connected to the top air outlet of the dryer. The connecting pipe is fixedly connected to the top of the screen air supply pipe. Several drying hoods are equidistantly fixedly connected to the front end of the connecting pipe and extend into the interior of the pickling tank. After the pickling is completed, the dryer is started, and hot air is blown into the interior of the connecting pipe through the air supply pipe and then blown out through the drying hood, so as to dry the preform rods inside the pickling tank.

[0009] A further improvement is that the pickling device includes a rotating unit, a cleaning unit, a liquid inlet unit and a filtering unit.

[0010] The rotating unit includes a rotating motor, a rotating shaft, a placing rack, and a rotating bearing. The rotating motor is installed on the left outer surface of the pickling tank. The two rotating bearings are respectively installed on the left and right sides of the inside of the pickling tank. The rotating shaft is connected to the output end of the rotating motor. The placing rack is fixedly connected to the right end of the rotating shaft and is rotatably connected to the inside of the rotating bearing. The preform rod is placed in the placing rack, and then the rotating motor is started to drive the rotating shaft to rotate, thereby driving the placing rack at the right end of the rotating shaft to rotate inside the rotating bearing, thereby driving the preform rod inside the placing rack to rotate and fully contact the pickling liquid inside the pickling tank.

[0011] A further improvement is that the cleaning unit includes a liquid dispensing pipe, a water injection pipe, and a filling nozzle. The liquid dispensing pipe is installed on the top of the pickling tank, the water injection pipe is fixedly connected to the right side of the liquid dispensing pipe, and several filling nozzles are equidistantly fixedly connected to the bottom of the liquid dispensing pipe, and the bottoms thereof extend into the interior of the pickling tank.

[0014] A further improvement is that a slide groove is opened on the front of the filter box, and the filter box is slidably connected to the inside of the slide groove. The filter box is regularly taken out from the inside of the slide groove to clean the filter screen inside to prevent impurities from clogging the filter screen and affecting the filtering effect.

[0015] A further improvement is that a drain pipe is fixedly connected to the right side of the bottom of the pickling tank, and electric sealing valves are respectively installed on the outer surfaces of the water injection pipe, the infusion pipe, the return pipe and the drain pipe.
