Description

Technical Field

[0001] This utility model belongs to the field of dry and wet mortar technology, specifically relating to a centrifugal solid waste crushing and screening integrated machine. Background Technology

[0002] Wet-mixed mortar refers to a mortar mixture made by mixing cementitious materials, fine aggregates, admixtures, water, and other components determined according to their performance characteristics in a certain proportion at a mixing plant. After being metered and mixed, the mixture is transported to the point of use by a mixer truck, stored in a special container, and used within a specified time. The working principle of wet-mixed mortar is similar to that of ready-mixed concrete; however, ready-mixed concrete mixing plants can simultaneously produce wet-mixed mortar.

[0003] The production of wet-mixed mortar requires the crushing and screening of the sand within the mortar to ensure that the sand particles are of uniform size. However, this crushing and screening process requires different devices, as it is not possible to use a single device to crush and screen the sand simultaneously. Utility Model Content

[0026] Reference Figure 1-4 The centrifugal solid waste crushing and screening integrated machine shown includes a shell body 1. A support ring 2 is provided on the top of the inner wall of the shell body 1. A centrifugal filter structure 3 is rotatably connected to the top of the support ring 2. An installation plate 4 is provided on the top of the shell body 1. A servo motor 5 is provided on one side of the top of the installation plate 4. A meshing gear 6 is provided at the output end of the servo motor 5. An outer crushing structure 7 is rotatably connected to the middle of the installation plate 4.

[0027] Furthermore, in the above technical solution, the centrifugal filtration structure 3 includes a filter baffle 301, which is rotatably connected to the top of the housing body 1. A collection groove 302 is provided in the middle of the bottom of the filter baffle 301. A feeding pipe 304 is provided at the bottom of the inner wall of the collection groove 302. The feeding pipe 304 is rotatably connected to the collection groove 302. An internal gear ring 303 is provided at the top of the inner wall of the filter baffle 301. The internal gear ring 303 meshes with a meshing gear 6. A feed groove 305 is opened at the bottom of the feeding pipe 304. A feeding screw 306 is provided inside the feeding pipe 304. One end of the feeding screw 306 is rotatably connected to the top plate 8. A transmission gear 307 is provided at one end of the feeding screw 306. The servo motor is activated. The servo motor 5 drives the meshing gear 6 to rotate, which in turn drives the internal filter baffle 301 to rotate. This allows the filter baffle 301 to centrifugally separate the crushed sand. Simultaneously, the sand also enters the collection tank 302 for further separation. When the rotational speed of the filter baffle 301 decreases, larger particles inside the sand enter the collection tank 302. At the same time, the meshing gear 6 also drives the external crushing structure 7 to rotate. The external crushing structure 7 drives the transmission gear 307 to rotate via the second gear 10, the inner and outer gear rings 1105, and the first gear 9. The transmission gear 307 drives the feeding screw 306 to rotate, causing the larger sand particles inside the collection tank 302 to re-enter between the internal crushing structure 11 and the external crushing structure 7 for further crushing.

[0028] Furthermore, in the above technical solution, the outer crushing structure 7 includes an outer crushing shell 701, which is rotatably connected to the inner wall of the mounting plate 4. A first crushing strip 702 is provided on the inner wall of the outer crushing shell 701. A transmission gear ring 703 is provided at the top of the inner wall and in the middle of the outer wall of the outer crushing shell 701. The transmission gear ring 703 in the middle of the outer wall of the outer crushing shell 701 meshes with a meshing gear 6. The inner crushing structure 11 includes an inner crushing shell 1101, which is rotatably connected directly below the top plate 8. A second crushing strip 1102 is provided on the outer wall of the inner crushing shell 1101. A feeding trough 1103 is opened in the middle of the inner crushing shell 1101, which is aligned with the feeding pipe 304. A support 1104 is provided on the top of the inner crushing shell 1101, and inner and outer gear rings 11 are provided on the top of the support 1104. 05, the outer wall of the inner and outer toothed rings 1105 meshes with the second gear 10, the second gear 10 meshes with the transmission toothed ring 703 on the top of the inner wall of the outer crushing shell 701, the inner wall of the inner and outer toothed rings 1105 meshes with the first gear 9, the first gear 9 meshes with the transmission gear 307, and the sand inside the dry and wet mixed mortar raw material is directly put into the space between the outer crushing shell 701 and the inner crushing shell 1101. The inner crushing shell 1101 is set in a frustum shape. Then the outer crushing shell 701 drives the inner crushing shell 1101 to rotate through the second gear 10. At the same time, the outer crushing structure 7 and the inner crushing structure 11 can rotate in opposite directions through the second gear 10. Then the second crushing strip 1102 on the outer wall of the inner crushing shell 1101 and the first crushing strip 702 on the inner wall of the outer crushing shell 701 crush the sand inside the dry and wet mixed mortar, so that the crushed sand enters the interior of the filter baffle 301 for centrifugal screening.
