Description

Technical Field

[0001] This utility model relates to the technical field of boehmite drying, and in particular to a pseudo-boehmite drying device. Background Technology

[0002] Boehmite, also known as monohydrate alumina or pseudo-boehmite, is a non-toxic, tasteless, odorless, white colloidal (wet) or powder (dry) substance with high crystal purity, good colloidal properties, strong adhesion, high specific surface area, and large pore volume. Its aqueous state is a thixotropic gel.

[0003] In existing boehmite drying devices, such as the boehmite drying device disclosed in utility model patent application number 201920075126.3, the utility model can prevent boehmite from adhering to the inner wall of the drying chamber through the vibration of the vibration motor, thus affecting the drying effect. At the same time, it can clean the ultraviolet lamp cover through ultrasonic vibration, increase the ultraviolet lamp transmittance, and increase the sterilization effect.

[0004] However, during the drying process of pseudoboehmite, the material is in a gel-like state due to its moisture, and stirring cannot ensure that the material is heated evenly. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a boehmite drying device that, by setting up a turning and scraping mechanism, not only can the mixing be made more uniform by using the up-and-down transport and turning method during the boehmite drying process, but also the material adhering to the inner wall can be cleaned.

[0006] The present invention provides a pseudo-boehmite drying device, which includes a heating mechanism; it also includes a vacuum mechanism, a stirring mechanism, a condensation mechanism and a scraping mechanism. The stirring mechanism is installed on the vacuum mechanism, the condensation mechanism is installed at the lower end of the vacuum mechanism, the heating mechanism is installed on the vacuum mechanism, and the scraping mechanism is installed inside the vacuum mechanism.

[0007] The vacuum mechanism performs vacuum treatment, the stirring mechanism transports the material upwards, the condensation mechanism performs low-temperature condensation, the heating mechanism heats and dries the material, and the scraping mechanism scrapes the inner wall. By opening the stirring mechanism, the material is transported upwards to form a circulating stirring process. At the same time, the scraping mechanism cleans the material adhering to the inner wall. By opening the vacuum mechanism, the internal vacuum accelerates drying. By opening the heating mechanism, the material is heated and dried. By opening the condensation mechanism, the extracted water vapor is condensed and collected. Thus, during the drying process of the pseudoboehmite, not only can the upward and downward transportation and stirring methods make the stirring more uniform, but the material adhering to the inner wall can also be cleaned.

[0008] Preferably, the vacuum mechanism includes a drying chamber and a vacuum pump, with the vacuum pump installed at the top of the drying chamber; the drying efficiency is improved by turning on the vacuum pump to perform vacuum treatment inside the drying chamber.

[0009] Preferably, the mixing mechanism includes a conveying auger, a spiral blade shaft, and a motor. The conveying auger is installed inside the drying chamber, and the spiral blade shaft is rotatably installed inside the conveying auger, with the input end of the spiral blade shaft extending to the upper side of the drying chamber. The motor is installed at the upper end of the drying chamber, and the output end of the motor is connected to the input end of the spiral blade shaft. By turning on the motor, the spiral blade shaft is driven to rotate, and while rotating, it is transported upward along the direction of the conveying auger for mixing.

[0010] Preferably, the condensation mechanism includes a water tank, a condenser, and pipes. The water tank is installed at the lower end of the drying chamber, the condenser is installed at the left end of the water tank, and the output end of the vacuum pump is connected to the input end of the condenser through a pipe. The intake air is condensed and discharged into the water tank by opening the condenser.

[0011] Preferably, the heating mechanism includes a heating chamber and a heating wire. The heating chamber is installed at the lower end of the drying chamber, and the heating wire is installed inside the heating chamber. The heating wire is energized to heat and dry the material inside the drying chamber.

[0012] Preferably, the scraping mechanism includes a scraper frame, a gear ring, a main gear, and a driven gear. The scraper frame is rotatably installed inside the drying chamber, the gear ring is installed on the scraper frame, the main gear is installed on the spiral blade shaft, and the driven gear is rotatably installed inside the drying chamber, with the driven gear meshing with both the gear ring and the main gear. The rotation of the spiral blade shaft causes the main gear to rotate, and the rotation of the main gear meshes with the driven gear to cause the driven gear to rotate. The rotation of the driven gear meshes with the gear ring to cause the gear ring to drive the scraper frame to rotate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by opening the stirring mechanism, the material is transported upward to form a circulating stirring; at the same time, the scraping mechanism cleans the material adhering to the inner wall; by opening the vacuum mechanism, the internal vacuum is accelerated to dry; by opening the heating mechanism, the material is heated and dried; and by opening the condensation mechanism, the extracted water vapor is condensed and collected. Thus, in the drying process of pseudo-boehmite, not only can the up-and-down transportation and stirring method be used to make the stirring more uniform, but the material adhering to the inner wall can also be cleaned.

[0024] The mixing mechanism 2 includes a conveying auger 21, a spiral blade 22 and a motor 23. The conveying auger 21 is installed inside the drying chamber 11.

[0026] The heating mechanism 4 includes a heating chamber 41 and a heating wire 42. The heating chamber 41 is installed at the lower end of the drying chamber 11, and the heating wire 42 is installed inside the heating chamber 41.

The driven gear 54 meshes with both the toothed ring 52 and the main gear 53.

[0028] By turning on the motor 23, the spiral blade shaft 22 is driven to rotate. As the spiral blade shaft 22 rotates, it is transported upward along the conveying auger 21 to form a circulating stirring. At the same time, the rotation of the spiral blade shaft 22 causes the main gear 53 to rotate. The main gear 53 meshes with the driven gear 54, causing the driven gear 54 to rotate.

[0029] like Figures 1 to 4 As shown, this utility model discloses a pseudo-boehmite drying device. During operation, the motor 23 drives the spiral blade shaft 22 to rotate. While rotating, the spiral blade shaft 22 transports materials upward along the conveying auger 21 to form a circulating stirring.

The driven gear 54 meshes with the gear ring 52, causing the gear ring 52 to drive the scraper frame 51 to rotate. The vacuum pump 12 is turned on to perform vacuum treatment in the drying chamber 11 to improve drying efficiency.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
