DETAILED DESCRIPTION

[0026] In order to make the purposes, technical schemes and advantages of the embodiments of the present application clearer, the technical schemes in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0029] The auxiliary processing mechanism 200 comprises a stirring assembly 210 and a solid-liquid separation assembly 220, the stirring assembly 210 is drivingly installed at the inner top of the preliminary filtration tank body 110, the hot filtration tank body 120 and the filter air-drying tank body 130 respectively, and the solid-liquid separation assembly 220 is installed in communication with the preliminary filtration tank body 110, and the hot filtration tank body 120 and the filter air-drying tank body 130 are provided with a filter assembly 230 in communication respectively.

[0030] The tank bodies of the hot filtration tank body 120 and the filter air-drying tank body 130 adopt a double-layer jacket structure, the inner layer is used for containing materials, the outer layer jacket is provided with heating pipes and cooling liquid for realizing the functions of heating and cooling, and the filter air-drying tank body 130 is connected with a dry gas supply device, such as a hot air generator or a nitrogen source, at the tank top ventilation opening. When the filtration is completed, the liquid discharge port is closed, the ventilation opening and the dry gas supply device are opened, the dry gas enters the tank, and under the action of the stirrer, the gas uniformly flows through the crystal surface and carries away the moisture to realize drying. Meanwhile, a heating coil is arranged at the bottom of the tank body to assist heating and improve the drying efficiency, and the liquid filtered by the hot filtration tank body 120 is discharged into the filter air-drying tank body 130.

[0031] Please refer to Figure 2 and Figure 3 The preliminary filtration tank body 110 comprises a first tank body 111, the inner bottom of the first tank body 111 is arranged in a conical shape, the bottom of the first tank body 111 is provided with a solid discharge pipe 113 in communication, and the top of the first tank body 111 is provided with a material conveying pipe 112 in communication and installation. The inner bottom of the first tank body 111 is arranged in a conical shape to facilitate solid precipitation and discharge.

[0032] The stirring assembly 210 includes a servo motor 211, which is fixedly installed on the top of the preliminary filtration tank 110, the hot filtration tank 120, and the filter drying tank 130. The servo motor 211 passes through the top of the preliminary filtration tank 110, the hot filtration tank 120, and the filter drying tank 130 and is connected to a transmission rod 212. An upper stirring plate 213 is installed on the outside of the transmission rod 212. Multiple upper stirring plates 213 are provided and are equally spaced and staggered on the outer wall of the transmission rod 212. The stirring speed and direction can be controlled by controlling the servo motor 211.

[0033] Please see Figure 3 The solid-liquid separation assembly 220 includes a connecting pipe 221. One end of the connecting pipe 221 is connected to a pump, and the other end slides into the interior of the first tank 111. The other end of the pump is connected to the heat filtration tank 120. A filter nozzle 222 is installed at the end of the connecting pipe 221 that extends into the first tank 111. A floating ring 223 is fixedly connected to the bottom outer ring of the filter nozzle 222. The filter nozzle 222 is inverted conical in shape, and multiple strip-shaped through holes are provided at the connection between the filter nozzle 222 and the floating ring 223.

[0034] A limiting clip 225 is snapped into the middle of the connecting pipe 221. A lifting rod 224 is installed at the bottom of the limiting clip 225. The lifting rod 224 is installed at the top of the first tank 111. The limiting clip 225 is used to wrap the connecting pipe 221 to facilitate the lifting of the end of the connecting pipe 221 located inside the first tank 111. When the water level in the first tank 111 drops, the lifting rod 224 drops. At this time, the filter nozzle 222 and the floating ring 223 at the end of the connecting pipe 221 will drop and continuously suck in liquid. The weight of the filter nozzle 222 will drive the floating ring 223 to press down. At this time, the strip-shaped through hole is also located in the liquid, and the pump can suck in the liquid. If there is less liquid, the floating ring 223 will be placed on a solid or at the bottom of the first tank 111. At this time, the liquid is difficult to reach the top of the strip-shaped through hole, and the pump is difficult to extract the liquid for solid-liquid separation.

[0035] Please see Figure 4 The filter assembly 230 includes a first three-way pipe 231, which is connected to the bottom outlets of the heat filtration tank 120 and the filter drying tank 130. Filters 232 are installed at both ends of the first three-way pipe 231, and a second three-way pipe 233 is installed at the other end of each filter 232. Valves are installed at the ends of the first and second three-way pipes 231 and 233 that connect to the filters 232. A support block 234 is installed at the bottom of the second three-way pipe 233. The filters 232 are positioned on both sides of the first and second three-way pipes 231 and 233 for easy replacement when cleaning is needed without affecting the operation of the equipment.

[0036] Working principle:

[0037] The primary filtering stage: the potassium persulfate raw material to be purified is transported into the first tank 111 of the primary filtering tank 110 through the feed pipe 112, and an appropriate amount of soaking solvent is added. The servo motor 211 is started to drive the transmission rod 212 and the upper stirring plate 213 to soak and stir the raw material. Since the bottom of the first tank 111 is conical, the insoluble impurities are precipitated at the bottom and discharged through the solid discharge pipe 113. The pump of the solid-liquid separation assembly 220 is started, and the filter suction nozzle 222 floats on the liquid surface under the action of the floating ring 223 to suck the upper clear liquid and transport it to the hot filtering tank 120 through the connecting pipe 221. The lifting rod 224 can adjust the height of the filter suction nozzle 222 according to the liquid level.

[0038] The hot filtering stage: after the clear liquid enters the hot filtering tank 120, the servo motor 211 drives the stirring assembly 210 to perform high-temperature stirring and dissolution. The dissolved solution is filtered while hot through the filter assembly 230 at the bottom of the hot filtering tank 120. The one-way valve at the communication end of the first three-way pipe 231 and the second three-way pipe 233 with the filter 232 is opened, and after the solution is filtered through the filter 232, the impurities are intercepted, and the filtrate enters the next stage. When one side of the filter 232 needs to be cleaned and replaced, the other side of the filter 232 is opened, and the side of the filter 232 is closed and disassembled for cleaning and replacement without stopping.

[0039] The filtering and air-drying stage: the filtered filtrate enters the filtering and air-drying tank 130, and the servo motor 211 drives the stirring assembly 210 to perform cooling and stirring crystallization. After crystallization is completed, low-temperature filtration and solid-liquid separation are performed through the filter assembly 230 at the bottom of the filtering and air-drying tank 130. The separated solids are dried in the filtering and air-drying tank 130, and finally the purified potassium persulfate product is obtained.

[0040] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
