Description

Technical Field

[0001] The utility model relates to the technical field of dry mortar screening, in particular to a screening device for dry mortar production. Background Art

[0002] Dry-mix mortar refers to a granular or powdery material made by physically mixing dried and sieved aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) in a certain proportion. It is transported to the construction site in bags or bulk and can be used directly after adding water and mixing. It is also called dry mortar, dry-mixed mortar, and dry-mixed powder. Some construction adhesives also belong to this category. Dry-mix mortar is used in the construction industry in thin layers to perform bonding, cushioning, protection and decoration functions, and is widely used in construction and decoration projects.

[0003] At present, some existing screening devices for dry-mix mortar production generally screen the materials for producing dry-mix mortar through screens or screen plates. However, when different production materials need to be screened, the screens or screen plates must be replaced according to the particle diameters of different materials so that the device can screen different production materials. This method is relatively time-consuming and labor-intensive to use, and the production efficiency is relatively low. For this reason, we propose a screening device for dry-mix mortar production to solve or improve the above problems. Utility Model Content

[0007] Furthermore, a discharge port is provided on the surface of the screening box body, and one end of the filter plate is located inside the discharge port.

[0008] Furthermore, a collecting bin is inserted inside the screening box body, and the collecting bin is located at one side of the bottom of the filter plate.

[0009] Furthermore, support feet are fixed to the bottom of the screening box body, and several groups of support feet are symmetrically fixed to the bottom of the screening box body.

[0010] Furthermore, the surface of the filter plate is provided with sieve holes, the surface of the adjustment plate is provided with sieve holes, and the number of the sieve holes provided on the adjustment plate surface and the sieve holes provided on the filter plate surface are the same and their positions overlap with each other.

[0011] Compared with the prior art, the utility model has the following beneficial effects: by setting an adjustment component, when different production materials need to be screened, the overlapping area between the sieve holes on the surface of the adjustment plate and the sieve holes on the surface of the filter plate can be changed by adjusting the position of the adjustment plate, thereby changing the area through which the material can pass through the sieve holes between the filter plate and the adjustment plate, thereby realizing the screening of materials of different diameters, without the need to replace the filter plate, which is relatively time-saving and labor-saving, and has relatively high production efficiency.

When the driving turntable 6 rotates, it will drive the rotating connecting rod 7 to move The filter plate 5 is inserted into the screening box body 1. The surface of the filter plate 5 is set at a certain inclination angle and the surface is provided with sieve holes. The sieve holes are provided in a plurality of groups on the surface of the filter plate 5. A collecting bin 12 is inserted into the screening box body 1. The collecting bin 12 is located at the bottom side of the filter plate 5. When the material falls from the bottom side of the filter plate 5, it will fall into the collecting bin 12 for storage. A handle is fixed on the surface of the collecting bin 12. The collecting bin 12 can be pulled out from the inside of the screening box body 1 by pulling the handle, so that the personnel can uniformly handle the materials stored in the collecting bin 12. The adjusting plate 14 is inserted into the filter plate 5. The adjusting plate 14 can move inside the filter plate 5. The surface of the adjusting plate 14 is provided with sieve holes. The number of sieve holes provided on the surface of the adjusting plate 14 is the same as that of the sieve holes provided on the surface of the filter plate 5, and their positions overlap with each other. The fixing plate 8 is fixed to the surface of the filter plate 5. One end of the connecting rod 7 is rotatably mounted on the bottom of the driving turntable 6, and the other end is rotatably mounted on the bottom of the fixing plate 8 through a rotating shaft. When the connecting rod 7 moves, the rotatably connected fixing plate 8 will be driven to move. When the fixing plate 8 moves, the fixed filter plate 5 will be driven to move. When the filter plate 5 moves, the internally inserted adjusting plate 14 will be driven to move. The surface of the screening box body 1 is provided with a discharge port. 13. One end of the filter plate 5 is located inside the discharge port 13. When there are relatively large particles inside the material that cannot fall through the sieve holes between the filter plate 5 and the adjustment plate 14, they will move along the inclined surface of the filter plate 5 to the side close to the discharge port 13 by gravity and fall from one end of the filter plate 5 through the discharge port 13. There is no need for personnel to manually clean the surface of the filter plate 5. It is relatively convenient to use and improves the production efficiency of the device.

When the adjusting knob 11 is rotated, the adjusting knob 11 will drive the threadedly connected threaded rod 10 to move, and when the threaded rod 10 moves, it will drive the fixed adjusting plate 14 to move. When the adjusting plate 14 moves, the overlapping area between the sieve holes on the surface of the adjusting plate 14 and the sieve holes on the surface of the filter plate 5 will change, thereby realizing the adjustment of the sieve hole passing area between the filter plate 5 and the adjusting plate 14.
