Description

Technical Field

[0001] The utility model relates to the technical field of silica gel processing, in particular to a block silica gel drying device. Background Art

[0002] Color-changing silica gel is an indicating adsorbent with high added value and high technical content, which is made from fine-porous silica gel with high active adsorption material as the basic raw material through deep processing. It is a high-end adsorption desiccant and generally has two shapes, one is spherical and the other is block. Color-changing silica gel has limited ability to absorb water. When the absorbed water reaches saturation, the silica gel will change color (usually to pink). At this time, it loses the ability to continue to absorb moisture. In order to restore the hygroscopic properties of silica gel, it needs to be dried to change its color back to its original blue so that it can continue to be used.

[0003] China Utility Model Announcement No.: CN220911876U includes a drying box and a supporting column supported on the bottom of the drying box, a two-way stirring mechanism is arranged inside the drying box, including an inner rotating column and an outer rotating stirring frame, the upper and lower ends of the inner rotating column are respectively rotatably nested with the upper and lower ends of the outer rotating stirring frame through bearings, the upper and lower ends of the outer rotating stirring frame are respectively rotatably fixed to the top and bottom side walls of the drying box through bearings, and the upper end of the outer rotating stirring frame The part of the upper end of the inner rotating column extending out of the top side wall of the drying box is equipped with a lower bevel gear, and the upper end of the inner rotating column extending out of the part above the upper end of the outer rotating stirring frame is equipped with an upper bevel gear, the driving bevel gear is meshed with the upper bevel gear and the lower bevel gear at the same time, and the driving bevel gear is driven by the motor to rotate, driving the upper bevel gear and the lower bevel gear to drive the two-way stirring mechanism to fully stir the material, thereby improving the stirring efficiency and increasing the uniformity of silica gel drying.

[0004] The applicant found that the patent had some deficiencies in use:

[0005] 1. Because the discharge port is too low, the dried silica gel cannot be adapted to collection boxes of different heights when collected through the collection box;

[0006] 2. Stirring the silicone with a stirring rod or stirring rack will increase the breakage of the silicone and reduce the service life of the silicone.

[0007] Therefore, the utility model designs a block silica gel drying device to solve the problems existing in the prior art. Utility Model Content

[0011] Preferably, a weighing module is provided on the top of the base, and the weighing module is located directly below the material pipe. The weighing module can detect the weight of the collection box. After reaching a predetermined weight, the electric valve can be controlled by the PLC controller to close and stop unloading, thereby avoiding the situation where the collection box is full but unloading continues due to negligence of the staff.

[0012] Preferably, a PLC controller is provided on the vertical plate, and the PLC controller is convenient for staff to control.
