Description

Technical Field

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

[0002] Gypsum powder, also known as putty powder, is mainly used for wall construction, grouting or wall leveling. There is also a colored gypsum powder that can play a certain decorative role. Gypsum powder can be used as a concrete expansion agent, anti-cracking agent and a main raw material for self-leveling mortar.

[0003] During the production and processing of gypsum powder, in order to ensure that the gypsum powder is in a dry state when used, drying equipment is used to dry the gypsum powder. Currently, when drying the gypsum powder, the gypsum powder is put into a drying box and stirred and dissipated by a stirring equipment. The gypsum powder is directly put into the stirring equipment, which leads to a large amount of agglomeration of the gypsum powder in the drying box, which not only prevents the gypsum powder from falling evenly into the mixing box, but also affects the efficiency of the heat dissipation of the gypsum powder. In addition, because the stirring equipment only dissipates the heat of the gypsum powder once through the stirring structure, and the heat dissipation efficiency of one heat dissipation has certain limitations, the gypsum powder that has been dried once needs to be put into the drying box again for drying, thereby extending the processing time of the gypsum powder drying.

An eccentric wheel 12 which is movably opposed to the sieve plate 5 is fixedly mounted on the second rotating shaft 11. The eccentric wheel 12 can intermittently oppose the sieve plate 5 when rotating, so that the sieve plate 5 can dynamically filter the gypsum powder.

[0027] A stirring assembly for stirring gypsum powder is installed on the partition 2;

[0028] The stirring assembly includes a stirring rod 16 rotatably mounted on the partition 2, and a gear 17 is fixedly mounted on the stirring rod 16. A sieve barrel 15 for filtering gypsum powder is integrally connected to the collecting cylinder 14. A screw rod 18 is provided on one side of the box body 1, and a coupling 19 is connected between the screw rod 18 and the rotating shaft 7, and the screw rod 18 and the rotating shaft 7 can be connected through the coupling 19.

The stirring rod 16 is vertically arranged and extends into the screen barrel 15, and the screw rod 18 and the support rod 21 are both horizontally arranged;

[0030] The rotating shaft 7 drives the screw rod 18 to rotate through the coupling 19, so that the nut 20 drives the connecting rod 23 and the rack 22 to move when sliding, and the rack 22 drives the stirring rod 16 to rotate through the meshing gear 17 when moving, so that the stirring rod 16 can stir the gypsum powder in the sieve barrel 15, and the fan can dissipate the heat of the gypsum powder in the lower chamber, and the upper chamber and the lower chamber in the box body 1 are used to heat and dissipate the gypsum powder respectively, so that the box body 1 as a whole can perform secondary drying on the gypsum powder, thereby improving the efficiency of gypsum powder drying;

[0031] It should be noted that the specific models and specifications of the heater, motor, fan, and coupling 19 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0032] The functional principle of the utility model can be explained through the following operation modes:

[0033] After the heater is turned on, the hot air discharged from the heater can preheat the upper cavity;

[0034] Put gypsum powder into the box 1, so that the gypsum powder falls onto the sieve plate 5;

[0035] The output end of the motor drives the rotating shaft 1 7 to rotate, and the rotating shaft 1 7 drives the rotating shaft 2 11 to rotate through the transmission belt 13, and the rotating shaft 2 11 drives the eccentric wheel 12 to intermittently resist the sieve plate 5. When the sieve plate 5 is stressed, it drives the slider to slide on the guide rod 4, and the spring 6 is stressed, so that the sieve plate 5 can dynamically filter the gypsum powder;

[0036] When the rotating shaft 1 7 rotates, the stirring rod 8 and the deflection plate 9 are driven to rotate. When the stirring rod 8 rotates, the stirring plate 10 is driven to stir the gypsum powder on the holder 3.

[0037] After the gypsum powder has dried for a certain period of time;

[0038] The motor stops running, the screw rod 18 is connected to the rotating shaft 7 through the coupling 19, and the nut 20 drives the connecting rod 23 and the rack 22 to move, so that the rack 22 can extend to the support rod 21;

[0039] The fan is turned on to discharge the gypsum powder in the upper chamber into the lower chamber through the pipe;

[0040] The wind discharged by the fan can dissipate the heat of the gypsum powder falling into the lower cavity;

[0041] Again, unprocessed gypsum is fed into the box 1 through the feed port;

[0042] The motor is turned on again, so that the stirring rod 8 and the stirring plate 10 can stir the gypsum powder in the upper cavity;

[0043] At the same time, when the motor drives the rotating shaft 7 to rotate, the screw rod 18 is driven to rotate through the coupling 19. When the screw rod 18 rotates, it drives the nut 20 to move to the left, so that the nut 20 drives the connecting rod 23 to move synchronously. When the connecting rod 23 drives the rack 22 to slide on the support rod 21, the rack 22 pulls the meshing gear 17, so that the gear 17 drives the stirring rod 16 to rotate on the partition 2. When the stirring rod 16 rotates, the gypsum powder in the sieve barrel 15 is stirred, and the cold wind can dissipate the heat of the stirred gypsum powder.

[0044] When the gypsum powder in the lower cavity has finished dissipating heat, the gypsum powder is discharged through the collecting tube 14 and the discharge port;

[0045] The gypsum powder in the upper cavity is then discharged into the lower cavity for heat dissipation, thereby achieving drying of the gypsum powder.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
