Description

Technical Field

[0002] Lightweight gypsum mortar is a green plastering material for indoor walls and ceilings, and a high-performance interior wall base leveling material. It is made of high-quality gypsum, light aggregate, environmentally friendly additives and other materials, and is refined after scientific formula preparation and automatic mixing. It is an energy-saving wall material.

[0003] When processing lightweight gypsum mortar, operators usually use a stirrer to mix the gypsum and cementitious materials in the mixing barrel. A certain amount of dust will be generated during the mixing process. The dust floating in the air is easily adsorbed on the painted wall surface, affecting the painting effect of the wall surface. When the operator uses the gypsum mortar, it is necessary to use a scooping tool to transfer the prepared gypsum mortar in the mixing barrel to the receiving container, which makes the material taking process cumbersome, and the gypsum mortar is easy to adhere to the inner wall of the mixing barrel. After the wall painting is completed, the operator needs to use a cleaning tool to clean it. The cleaning process is time-consuming and labor-intensive, which increases the work intensity of the user.

[0064] The working principle of this device is:

[0065] When preparing gypsum mortar, one end of the rotary joint 15 is connected to a high-pressure water source. The water source passes through the rotary joint 15, the rotary tube 17 and the connecting tube 18 in sequence and is sprayed out by a plurality of atomizing nozzles 19. Raw materials are added to the mixing tank 5 through the feeding hopper 4. The driving motor 28 drives the driving shaft 11 and the stirring blades 10 to rotate. At the same time, the driving shaft 11 also drives the transition tube 13 and the rotary tube 17 to rotate, and then drives the connecting tube 18 and the atomizing nozzles 19 to rotate. The stirring blades 10 stir the raw materials in the mixing tank 5. The atomized water source sprayed out by the atomizing nozzles 19 can not only prevent the powder generated during the mixing process from spreading and realize the dust reduction function, but also improve the uniformity of contact with the raw materials at the bottom of the mixing tank 5.

[0066] When using the prepared gypsum mortar, push the push handle 3, and at the same time, with the cooperation of the universal wheel 1, move the equipment to the desired position, control the motor 34 to drive the driving gear 35, the driven gear 36, the rotating shaft 9 and the mixing tank 5 to rotate, and the mixing tank 5 is tilted, so that one end of the square discharge pipe 6 is downward, and the material receiving container 7 is placed under the port of the square discharge pipe 6.

At the same time, the equipment can be quickly moved according to needs, which improves the practicality of the equipment;

[0067] When cleaning the gypsum mortar on the inner wall of the mixing tank 5, the first telescopic cylinder 29 is extended to drive the lifting plate 8, the drive shaft 11 and the mixing blade 10 to descend. With the cooperation of the fixed sleeve 24 and the swing plate 23, the sliding plate 20 and the upper scraper 21 slide horizontally. When the lifting plate 8 descends to the lowest position, the upper scraper 21 abuts against the inner wall of the mixing tank 5, and the lower scraper 27 abuts against the inner bottom of the mixing tank 5. The control motor 34 drives the drive shaft 11, the mixing blade 10, the sliding plate 20, the upper scraper 21 and the lower scraper 27 to rotate. The upper scraper 21 and the lower scraper 27 clean the gypsum mortar on the inner wall and the inner bottom of the mixing tank 5. The cleaned gypsum mortar is discharged to the outside of the drying tank through the square discharge pipe 6, thereby realizing the function of quickly cleaning the gypsum mortar inside the mixing tank 5.
