Description

Technical Field

[0001] The utility model relates to the technical field of gypsum production, and more specifically, to a stirrer for gypsum production. Background Art

[0002] Gypsum is a monoclinic mineral and a hydrate whose main chemical component is calcium sulfate (CaSO4). Gypsum is a widely used industrial material and building material. It can be used as a cement retarder, gypsum building products, model making, medical food additive, sulfuric acid production, paper filler, paint filler, etc. Gypsum needs to be continuously stirred and mixed by a mixer during the production process.

[0003] Most of the existing agitators for gypsum production use a motor to drive the stirring blades to rotate, and use multiple stirring blades to stir the materials required for gypsum production. It is not convenient to mix the materials at the bottom with the materials on the upper side, resulting in poor material stirring effect. The feeding port of the existing agitators for gypsum production is set at the top of the mixing barrel. Some mixing barrels are at a high height, which is not convenient for people to add the materials required for gypsum production into the mixing barrel. In addition, the discharge pipes of the existing agitators for gypsum production are mostly installed at the bottom or the lower side of the mixing barrel. The distance between the discharge pipe and the ground is short, which is not convenient for discharging the evenly stirred materials into the interior of equipment at different heights, reducing the practicality of its use.

[0031] In the present embodiment, when it is necessary to add materials to the inside of the mixing barrel 1, the second valve 11 is opened and the first valve 8 is closed, and the materials are added to the inside of the feeding box 10. The materials in the feeding box 10 fall into the inside of the first feeding pipe 6 through the second connecting pipe 9, and the feeding shaft 14 and the spiral blades 15 are driven by the second motor 13 to rotate, so that the materials on the bottom side of the first feeding pipe 6 are transported to the inside of the second feeding pipe 12, and fall into the feeding hopper 2 and the mixing barrel 1 through the discharge pipe 16. Since the height of the feeding box 10 is lower than the height of the mixing barrel 1, people are prevented from climbing up to add materials to the inside of the mixing barrel 1, which improves the convenience of people adding materials to the mixing barrel 1.

The side end of the first material delivery pipe 6 is located below the swivel 18 and is fixedly connected to a fixed block 20. The fixed block 20 is threaded with a fixing screw 21.

[0033] In this embodiment, the swivel 18 is rotated, and the swivel 18 drives the multiple connecting plates 19, the fixed ring 17, the second feed pipe 12 and the discharge pipe 16 to rotate, and the direction of the discharge pipe 16 is adjusted to facilitate rotating the discharge pipe 16 to the upper side of the feeding hopper 2 or rotating the discharge pipe 16 to the upper side of the material guiding mechanism. After the discharge pipe 16 is rotated to the corresponding position, the fixing screw 21 is tightened so that the top end of the fixing screw 21 is tightly pressed against the bottom end of the swivel 18, thereby fixing the swivel 18, the multiple connecting plates 19, the fixed ring 17, the second feed pipe 12 and the discharge pipe 16.

[0034] See also Figure 1 The material guiding mechanism includes a material guiding box 22, which is fixedly installed on the side end of the mixing barrel 1. The side of the bottom end of the material guiding box 22 away from the first material conveying pipe 6 is connected to the first discharge pipe 23, and the outside of the first discharge pipe 23 is slidably provided with a second discharge pipe 24, and the second discharge pipe 24 is fixedly connected with a first fixing plate 25, and the first fixing plate 25 is rotatably connected with a screw 26. The side end of the material guiding box 22 is fixedly connected with a second fixing plate 27, and the second fixing plate 27 is threadedly connected to the screw 26. The bottom end of the screw 26 is fixedly connected with a handle 28 for facilitating the rotation of the screw 26.
