Description

Technical Field

[0001] This utility model relates to the field of block production technology, and in particular to a raw material screening device for BM lightweight aggregate interlocking blocks. Background Technology

[0002] In the production process of BM lightweight aggregate interlocking blocks, BM lightweight aggregate usually includes relatively loose particles and larger block materials. However, these raw materials are prone to forming large blocks due to moisture and adhesion during storage and transportation. These materials are not only difficult to screen through traditional screens, but also cause trouble for subsequent production operations.

[0003] Existing block raw material screening equipment mostly adopts a single-layer screen structure. Although it can screen most materials, it is not effective in handling materials that are sticky, wet, or lumpy. Furthermore, during the storage, transportation, or feeding process, the high moisture content or uneven particle size of lightweight aggregates can easily cause material adhesion, resulting in the formation of large lumps. These lumps are not only difficult to pass through the screen, but also cause equipment blockage, affecting production efficiency.

[0004] In addition, the current screening device has poor material flowability and the material residence time during the screening process is too short, which fails to allow the material to pass through the screen effectively, resulting in poor screening effect. This is especially true when processing materials with large volume and high moisture content, where the screening efficiency is reduced, resulting in poor material screening effect and low output.

A predetermined distance is maintained between the cover plate and the first screen, and between the first screen and the second screen. The mesh size of the first screen is larger than that of the second screen.

[0009] The lower end face of the cover plate is provided with several baffles arranged in an array along the first direction. The upper and lower end faces of the first screen are respectively provided with several push rods and several guide plates.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 3 A BM lightweight aggregate interlocking block raw material screening device includes: a support frame 1, a vibrating box 2, a vibration drive component 3, a cover plate 4, a first screen 5, and a second screen 6.

[0025] The upper surface of the support frame 1 is provided with a vibration box 2. The vibration box 2 has an inlet end and an outlet end at both ends in the first direction. The side wall of the vibration box 2 is equipped with a vibration drive 3. The inner cavity of the vibration box 2 is arranged with a cover plate 4, a first screen 5, and a second screen 6 in an upper and lower position. The cover plate 4 and the first screen 5, and the first screen 5 and the second screen 6 maintain a predetermined distance. The mesh diameter of the first screen 5 is larger than that of the second screen 6.

[0026] The lower end face of the cover plate 4 is provided with a plurality of baffles 7 arranged in an array along the first direction. The upper end face and the lower end face of the first screen 5 are respectively provided with a plurality of push rods 8 and a plurality of guide plates 9. The baffles 7, push rods 8 and guide plates 9 are arranged in a front-to-back position in the first direction, and the guide plates 9 extend in the opposite direction of the first direction.

[0027] In the specific use of the raw material screening device of this application, refer to... Figure 2The vibration drive 3 drives the vibration box 2 to vibrate, and the vibration motion is clockwise. Based on the double-layer screen mechanism formed by the first screen 5 and the second screen 6, several push rods 8 are provided on the upper surface of the first screen 5, and several baffles 7 are provided on the lower surface of the cover plate 4. After the material enters the upper surface of the first screen 5 from the inlet end, the material with a particle size smaller than the inner diameter of the mesh of the first screen 5 falls through the mesh, while the material with a particle size larger than the inner diameter of the mesh of the first screen 5 moves towards the outlet end under the driving force of the vibration drive 3. During the movement of the material towards the outlet end, it impacts the baffles 7 for the first breakage, and under the force of the push rods 8 pushing the material towards the inlet end, the material undergoes a second breakage operation. This increases the overall movement distance of the material, increases the screening time, and thus improves the screening quality.

[0028] Material falling through the mesh of the first screen 5 falls onto the guide plate 9. Based on the guide plate 9 extending in the opposite direction to the first direction, it applies a force to the material in the direction of the inlet, further increasing the material's movement distance on the second screen 6 and further increasing the screening time, thereby improving the screening quality.

[0029] This utility model proposes a screening device for BM lightweight aggregate interlocking block raw materials. Addressing the stickiness issue caused by BM lightweight aggregate during storage and transportation, a double-layer screening of the material is achieved through a first screen 5 and a second screen 6, ensuring that the output material particle size meets the requirements of subsequent operations. Simultaneously, a baffle 7 and a push rod 8 collide with the material to break up adhered material blocks, decomposing large blocks into smaller pieces. The push rod 8 and guide plate 9 further push the material in the opposite direction, increasing the screening time within the vibrating chamber 2, thereby improving the material screening quality and increasing the output volume after screening.

[0030] Meanwhile, a blower 10 is installed inside the vibrating chamber 2. The blower 10 is located on the side of the first screen 5 facing the inlet end, and the output end of the blower 10 is flush with the upper surface of the first screen 5. The airflow output by the blower 10 moves along the first direction, which increases the airflow velocity and improves the evaporation efficiency of moisture in the material. At the same time, when the airflow with increased velocity comes into contact with the material, it will give the material a driving force to move towards the outlet end, thereby increasing the motion force between the material and the first screen 5 and the cover plate 4, increasing the collision force between the material and the push rod 8 and the stop rod 7, breaking up some of the material blocks that are stuck together, increasing the degree of material breakage, and increasing the output of the material after screening.

[0031] In this case, the upper end of the second screen 6 is provided with several broken end blocks 11 corresponding to the output ends of several guide plates 9. The material passing through the mesh of the first screen 5 comes into contact with the guide plates 9 and is guided by the guide plates 9 to change the direction of movement, so that the material falls onto the broken end blocks 11 and collides with the broken end blocks 11. At the same time, the several guide plates 9 on the upper end of the second screen 6 will also collide with the material moving on the upper end of the second screen 6, further improving the screening quality of the material.

[0032] Correspondingly, the damaged end block 11 adopts a rhomboid cone structure, the cross section of the damaged end block 11 adopts a rhomboid structure, and the two axis lines of the cross section of the damaged end block 11 are consistent with the first direction and the second direction, respectively.

[0033] For example, the guide plate 9 includes a first connecting part 901 and a second connecting part 902 that are connected to each other. The free end of the first connecting part 901 is connected to the lower end face of the first screen 5. The first connecting part 901 and the second connecting part 902 are arranged at a predetermined angle.

[0034] The second connecting part 902 has guide notches arranged along the second direction, and protrusions of the second connecting part 902 are formed between adjacent guide notches. The second direction is arranged perpendicular to the first direction. The guide notches are aligned with the broken end block 11 so that the material falling from the guide notches can directly collide with the broken end block 11. At the same time, the material falling from the protrusions of the second connecting part 902 is located on the side of the corresponding block 20 facing the inlet end, so that the material can collide with the block 20 during the subsequent movement towards the outlet end.

[0035] Meanwhile, in order to filter some oversized materials, the inlet end of the vibrating box 2 is equipped with several dividing rods 12, and through holes are formed between adjacent dividing rods 12 for materials to enter the inner cavity of the vibrating box 2, so as to prevent oversized materials from entering the inner cavity of the vibrating box 2 and affecting the service life of the device.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
