Description

Technical Field

[0001] This utility model relates to the technical field of aggregate screening devices, specifically an aggregate screening device for concrete block processing. Background Technology

[0002] In the process of concrete block processing and production, aggregate screening is a key process to ensure the quality of blocks. Its core lies in separating aggregates of different particle sizes through screening devices to meet the precise requirements of aggregate particle size in subsequent production. Traditional aggregate screening devices are prone to generating a large amount of dust during operation due to the collision and friction between aggregates and the vibration screening process. Dust is usually handled by a single dust collection structure, which is insufficient to fully cover the dust-generating areas inside the screening box. This results in incomplete dust collection, and the uncollected dust will permeate the working environment. On the one hand, it will cause serious harm to the respiratory system of operators, and long-term exposure can easily lead to occupational diseases. On the other hand, dust adhering to the surface of equipment parts will accelerate equipment wear, reduce equipment lifespan, and may also affect the screening accuracy of aggregates, thus adversely affecting the final quality of concrete blocks. Utility Model Content

[0003] The purpose of this invention is to provide an aggregate screening device for concrete block processing, which solves the problem that dust is usually handled by a single dust collection structure, which is difficult to fully cover the dust-generating area inside the screening box, resulting in incomplete dust collection. Uncollected dust will diffuse in the working environment, which will seriously harm the respiratory system of operators and easily cause occupational diseases with long-term exposure. Dust adhering to the surface of equipment parts will accelerate equipment wear, reduce equipment service life, and may also affect the aggregate screening accuracy, thus adversely affecting the final quality of concrete blocks.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an aggregate screening device for concrete block processing, comprising a base plate, a screening box fixedly connected to the top of the base plate, a cover plate movably connected to the top of the screening box, a screening barrel inside the screening box, a screening screen fixedly connected inside the screening barrel, a U-shaped frame at the bottom of the screening box, the inner side of the U-shaped frame extending to the inner side of the screening box, the surface of the U-shaped frame fixedly connected to the surface of the screening barrel, a vibration component fixedly connected to the bottom of the U-shaped frame, a door panel movably connected to the right side of the screening box, a dust collection mechanism inside the screening box, and a dust collection mechanism fixedly connected to the top of the base plate, achieving efficient aggregate screening. Simultaneously, the dust collection mechanism and the dust collection mechanism work together to reduce dust pollution during the screening process. The U-shaped frame connects the screening barrel and the vibration component, improving screening stability. The door panel design facilitates the removal of the screened aggregate. The overall structure is compact and functionally complete.

[0005] Preferably, the dust collection mechanism includes a first dust collection plate, which is fixedly connected to the bottom of the cover plate. A second dust collection plate is fixedly connected to the left side of the inner wall of the screening box. A dust collection pipe is provided on the left side of the screening box. The input end of the dust collection pipe is connected to the output ends of the first and second dust collection plates respectively. A dust collection box is connected to the bottom of the dust collection pipe. A fan is connected to the front of the dust collection box. The first and second dust collection plates adsorb dust from the bottom of the cover plate and the left side of the screening box respectively. The dust is introduced into the dust collection box through the dust collection pipe. The fan provides power to ensure the dust collection effect. The multi-directional dust collection design can comprehensively capture the dust generated during screening and prevent dust from accumulating in the screening box or leaking out.

[0006] Preferably, the dust collection mechanism includes a sealing plate located on the left side of the dust collection box. A drawer is fixedly connected to the right side of the sealing plate and located inside the dust collection box. A filter screen is fixedly connected inside the drawer. A fixing frame is movably connected to the left side of the dust collection box. The inner wall of the fixing frame is in contact with the surface of the sealing plate. A lever is fixedly connected to the left side of the fixing frame. The filter screen can intercept dust to achieve solid-gas separation. The sealing plate ensures the airtightness of the dust collection box. The fixing frame limits the sealing plate to prevent it from loosening. The lever facilitates the operation of the fixing frame. The overall structure makes the dust collection and cleaning process convenient and can avoid secondary dust diffusion.

[0007] Preferably, the bottom of the fixing frame is provided with a support bar, the surface of which is fixedly connected to the left side of the dust collector box. The support bar is located at the top of the fixing frame and can support the fixing frame, preventing it from sagging due to its own weight or external force, ensuring that the fixing frame is always in close contact with the sealing plate, maintaining the limiting effect on the sealing plate, and ensuring the sealing performance of the dust collector box.

[0008] Preferably, a handle is fixedly connected to the left side of the sealing plate. The handle is located on the top of the base plate. The handle is fixed to the left side of the sealing plate and located on the top of the base plate. The operator can easily pull the sealing plate by holding the handle, thereby pulling the drawer out of the dust collection box without the need for additional tools, which simplifies the process of taking out the drawer and makes it easy to quickly clean the dust collected in the drawer.

[0009] Preferably, counterweights are fixedly connected to both the front and rear sides of the left side of the fixing frame. The counterweights are located on the top of the sealing plate and use their own weight to increase the pressure of the fixing frame on the sealing plate, so that the sealing plate fits more tightly with the dust collector box, preventing the sealing plate from loosening due to vibration or other factors, and ensuring that the sealing performance of the dust collector box is not affected.

[0010] Preferably, a guide plate is fixedly connected to the bottom of the inner wall of the screening box. The guide plate is located on the left side of the door panel. The inclined structure can guide the aggregate falling after screening to gather towards the door panel, avoiding the aggregate from being dispersed and accumulated at the bottom of the screening box. This makes it easier for operators to collect the aggregate when opening the door panel and reduces aggregate residue.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by adding a dust collection mechanism and other structures to the screening barrel, effectively reduces the pollution of the working environment by dust diffusion while efficiently completing the aggregate screening operation.

[0012] 2. This utility model improves the efficiency and accuracy of aggregate screening by adding a vibration component to the screening barrel. The vibration component drives the screening barrel to vibrate, and the door panel facilitates the subsequent removal and processing of aggregate. Attached Figure Description
