Description

Technical Field

[0001] The utility model belongs to the technical field of phenolic plastic processing and relates to a phenolic plastic production drying device. Background Art

[0002] Phenolic plastic is a polymer material. Phenolic plastic is also called bakelite powder, which is a kind of synthetic resin made by polycondensation of phenolic compounds and aldehyde compounds. After the phenolic plastic particles are processed, they need to be dried by drying equipment.

[0003] However, the prior art still has the following problems:

[0004] The prior art is to directly place the phenolic plastic particles into the drying equipment and drive the hot air blower to perform hot air drying on them. However, due to the different sizes of the particles accumulated inside the drying chamber, the drying time is also different, resulting in some smaller particles being dried but not being discharged in time, so that some of the dried particles will block the hot air from blowing towards the undried resin, reducing the drying efficiency. Utility Model Content

[0005] The utility model aims to address the deficiencies of the prior art and propose a phenolic plastic production drying device to solve the technical problem mentioned in the background technology that the prior art cannot discharge small-volume dried phenolic plastic particles in time, occupying the internal space of the drying device and thus reducing the drying efficiency.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A phenolic plastic production drying device, characterized in that it comprises:

[0008] Drying box;

[0009] A drying cylinder, the drying cylinder is rotatably installed in the drying box, and the peripheral wall of the drying cylinder is provided with a plurality of drying holes;

[0010] A stirring member, the stirring member is rotatably arranged in the drying drum;

[0011] A screening plate, the screening plate is fixedly installed on the inner wall of the drying drum near the bottom, the screening plate has two subdivided areas, two closed areas, and two coarse subdivided areas, the subdivided areas, the closed areas, and the coarse subdivided areas are arranged alternately, the subdivided areas have a number of fine leakage holes penetrating the screening plate, and the coarse subdivided areas have a number of coarse leakage holes penetrating the screening plate;

[0012] An adjusting disk, the adjusting disk is embedded in the drying drum, the upper end of the adjusting disk is in contact with the lower end of the screening disk, the adjusting disk is provided with leaks corresponding to the fine and coarse zones, and the adjusting disk can block the fine leak holes 8 and the coarse leak holes after rotation;

[0013] An annular block, the annular block is sleeved on the outer wall of the adjusting disk, and the inner wall of the drying cylinder is provided with an annular groove for embedding the annular block;

[0014] The adjusting cylinder is fixed on the inner wall of the drying box and located on one side of the drying drum. The drying drum is provided with an adjusting groove connecting the annular groove and the inner cavity of the drying box. The telescopic end of the adjusting cylinder is fixed with a supporting block which can pass through the adjusting groove and abut against the annular block.

[0015] Working principle:

[0016] The rotation of the drying drum can drive the phenolic plastic particles in the drying drum to rotate synchronously, so that the phenolic plastic particles in the drying drum are evenly dried by hot air, thereby improving the drying effect. The stirring piece rotates and stirs the materials in the drying drum, so as to avoid the phenomenon of incomplete drying of the inner layer materials caused by accumulation. After drying for a certain period of time, the smaller phenolic plastic particles are dried, and the abutment block is driven by the adjusting cylinder to pass through the adjusting groove and abut against the annular block. The annular block applies an extrusion force to the adjusting disk, so that the drying drum can rotate relative to the adjusting disk. The drying drum drives the screening disk to rotate synchronously, and when the subdivided area of ​​the screening disk coincides with the leakage of the adjusting disk, the adjusting cylinder is driven to drive the abutment block to move outside the drying drum. At this time, the coarse leakage hole is blocked by the adjusting disk, and the fine leakage hole is connected with the leakage hole. The smaller phenolic plastic particles in the drying drum can fall out of the drying drum through the fine leakage hole and the leakage hole in turn.

[0017] When all the phenolic plastic particles in the drying drum are dried, the adjusting cylinder is driven to drive the abutting block to pass through the adjusting groove and abut against the annular block. The annular block applies an extrusion force to the adjusting disk, so that the drying drum can rotate relative to the adjusting disk. The drying drum drives the screening disk to rotate synchronously, and when the coarse partition of the screening disk coincides with the leakage of the adjusting disk, the adjusting cylinder is driven to drive the abutting block to move outside the drying drum. At this time, the fine leakage hole is blocked by the adjusting disk, and the coarse leakage hole is connected with the leakage. The larger phenolic plastic particles remaining in the drying drum can fall out of the drying drum through the fine leakage hole and the leakage in turn;

[0018] The beneficial effects of the utility model are:

[0019] The utility model provides a rotatable drying drum, and the drying drum can make the phenolic plastic particles in the drying drum dry evenly during the rotation process, thereby improving the drying effect; by providing a rotatable stirring member, the phenolic plastic particles in the drying drum can be stirred, thereby avoiding the phenomenon of incomplete drying of the inner layer materials due to accumulation, and further improving the drying efficiency; by providing an adjusting cylinder, abutting blocks, a screening plate and an adjusting plate, when the small-volume phenolic plastic particles in the drying drum are dried, the adjusting cylinder can be driven to drive the abutting blocks to pass through the adjusting grooves and abut against the annular blocks, and the annular blocks A squeezing force is applied to the adjusting disk so that the drying cylinder can rotate relative to the adjusting disk. The drying cylinder drives the screening disk to rotate synchronously, and when the subdivided area of ​​the screening disk coincides with the leakage opening of the adjusting disk, the adjusting cylinder is driven to drive the abutment block to move outside the drying cylinder. At this time, the coarse leakage hole is blocked by the adjusting disk, and the fine leakage hole is connected with the leakage opening. The smaller phenolic plastic particles in the drying cylinder can fall out of the drying cylinder through the fine leakage holes and the leakage opening in turn, which can effectively discharge the dried small-volume phenolic plastic particles in advance, thereby further improving the drying efficiency of the remaining large-volume phenolic plastic particles in the drying cylinder.
