Description

Technical Field

[0001] The utility model belongs to the technical field of cement production, and in particular relates to a raw material stirring and discharging device for cement production. Background Art

[0002] As an essential building block for the construction industry, cement is widely used worldwide. During cement production, the quality of raw materials and the uniformity of their mixing directly impact the performance of the final product. Therefore, efficient mixing equipment is a key factor in ensuring cement quality.

[0003] Traditional raw material mixing equipment used in cement production typically only provides a mixing function, lacking an effective discharge mechanism. This results in material clogging or residue remaining in the mixing drum during discharge, impacting production efficiency and product quality. Furthermore, due to the simple internal structure of the mixing drum, traditional equipment often struggles to completely remove viscous materials, such as certain cement raw material mixtures with specific ratios. This results in wasted resources and may contaminate subsequent batches of product.

[0004] To improve these conditions, various improvements have emerged in existing technologies, such as adding vibration devices to facilitate smooth material discharge or adopting variable-angle designs to enhance material flow. However, these solutions often suffer from high complexity, difficult maintenance, and insufficient adaptability to materials of varying viscosities.

[0005] For example, the Chinese utility model patent with authorization announcement number CN215540083U discloses a raw material mixing device for cement production, which can drive the second groove wheel to rotate through the mutual cooperation between the motor, arc plate, stirring rod, steel brush, first groove wheel, belt and second groove wheel, etc., and the second groove wheel drives the stirring rod to rotate through the belt and the first groove wheel, so that the stirring rod drives the steel brush to rotate, so that the cement adhered to the inner wall of the first box can be scraped off by the steel brush. However, its disadvantages are that it is inconvenient to load and process the material during discharge, the operation is troublesome, the structure is complex, and the production cost is high.

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a raw material stirring and discharging device for cement production.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0015] 2. The bag can be fastened to the port of the discharge pipe through the clamp to prevent it from scattering during the bagging process, saving subsequent cleaning time, and the structure is simple and easy to maintain;

[0016] 3. The vibration of the vibrator can completely drop the raw materials adhering to the receiving plate into the discharge pipe to avoid leakage, enhance material fluidity and discharge smoothness, simplify the maintenance process, and improve overall production efficiency and product quality;

[0017] 4. By mixing the raw materials in a closed mixing barrel, it is possible to avoid the occurrence of a large amount of dust during mixing, thus improving the working environment of the staff;

[0018] 5. The opening and closing between the two receiving plates are achieved by the extension and retraction of the piston rod of the hydraulic cylinder or the cylinder. The hydraulic cylinder or the cylinder has a large load-bearing capacity, and the two receiving plates can be tightly fitted by rubber blocks to avoid leakage during the mixing process.

[0027] The switch valve 3 is closed when not in use. When in use, the switch valve 3 is opened to quickly drop the raw materials in the mixing barrel 4 into the bag through the discharge pipe 12, avoiding leakage or dust. In addition, the bag can be fastened to the end of the discharge pipe 12 by the clamp 2 to prevent it from being scattered during the bagging process, saving subsequent cleaning time.

[0028] Example 2:

[0029] A raw material mixing and discharging device for cement production is different from Example 1 in that the material receiving plates 9 and the telescopic mechanism 10 are both provided at two locations, and a rubber block 13 is provided between the two material receiving plates 9. The rubber block 13 is installed on any one of the material receiving plates 9. The two material receiving plates 9 are tightly fitted together by the rubber block 13 to avoid leakage during the mixing process.

[0030] Furthermore, one or more vibrators 11 are provided at the bottom of the receiving plate 9. The vibration of the vibrator 11 can completely drop the raw materials adhering to the receiving plate 9 into the discharge pipe 12 to avoid leakage.

[0031] Furthermore, the stirring mechanism includes a stirring shaft 7 and a stirring blade 8 mounted on the stirring shaft 7. One end of the stirring shaft 7 is connected to a reduction motor 6, which is mounted on the outside of the stirring barrel 4.

The bag is fastened to the port of the discharge pipe 12 by the clamp 2 to prevent scattering during the bagging process. Then, by opening the switch valve 3, the raw materials inside the mixing barrel 4 can be quickly dropped into the bag through the discharge pipe 12, or a large receiving barrel can be placed directly at the lower end to avoid leakage or dust, thereby improving efficiency.
