Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, specifically to a raw material particle size screening device for casting processing. Background Technology

[0002] A raw material particle size screening device for casting processing is a device used to screen casting raw materials by particle size. Its main purpose is to separate raw material particles of different sizes to meet specific production needs.

[0003] A raw material particle size screening device for brick making machines with a dust suppression module is disclosed in authorization announcement number CN218591063U. By setting a screening frame that slopes downwards from left to right inside the screening box, with the bottom plate of the screening frame serving as a screening mesh, the device can screen the brick raw materials, removing larger particles and controlling the particle size of the raw materials. Rubber fixing belts extending outwards and fixed to the inner wall of the screening box are provided on the front, back, and left sides of the top frame of the screening frame. The elasticity of the rubber fixing belts meets the vibration requirements of the screening frame. When the vibration motor at the left end of the screening frame runs, it can accelerate the screening efficiency of the brick raw materials on the screening mesh. Furthermore, the rubber fixing belts, after fixing the screening frame to the inner wall of the screening box, can concentrate all the brick raw materials into the screening frame, solving the problem of material leakage during the screening process in existing screening structures. Simultaneously, the included dust collection box can remove dust from inside the screening box.

[0004] As shown in the above equipment, although the existing raw material particle size screening device for casting processing has made up for the problem of raw material leakage during the screening process in the existing screening structure, and the dust removal box can remove dust inside the screening box, it may not be possible to accurately screen out raw materials that meet specific particle size requirements through only one screening, resulting in unstable quality of casting products. For example, surface roughness and dimensional accuracy may not meet the standard requirements. Utility Model Content

[0026] See Figures 1-6 This utility model provides the following two technical solutions:

[0027] First embodiment: A raw material particle size screening device for casting processing, including a screening box 1, and further comprising:

[0028] Secondary screening mechanism 8 is located inside screening box 1 and is used for screening the particle size of raw materials for casting processing.

[0029] Dust extraction component 9 is installed on the outer wall of screening box 1 and is used to extract dust carried by the particle size of raw materials used for casting processing.

[0033] The secondary screening mechanism 8 includes a mounting frame 81, which is located inside the screening box 1. A drive assembly A82 is fixedly mounted on the inner wall of the mounting frame 81. A gear B is fixedly connected to the output end of the drive assembly A82.

The gate body 812 meshes with the gear B. A slide groove A84 is opened on the outer wall of the mounting frame 81. An inclined plate 85 is fixedly connected to the outer wall of the mounting frame 81. A cleaning assembly 86 is provided on the inner wall of the mounting frame 81. A mounting plate 87 is fixedly connected to the outer wall of the mounting frame 81. A hydraulic rod 88 is fixedly connected to the top of the mounting plate 87.

A vibrating screen B811 is fixedly connected to the other end of the connecting rod 810.

[0034] The cleaning assembly 86 includes a grooved plate 861, which is fixedly installed on the inner wall of the mounting frame 81. A threaded rod 862 is fixedly installed on the inner wall of the grooved plate 861, and a limit slide rail 863 is fixedly installed on the inner wall of the grooved plate 861.

[0035] This raw material particle size screening device for casting processing is equipped with a secondary screening mechanism 8. The secondary screening mechanism further refines the screening process, effectively removing impurities and particles that do not meet the particle size requirements from the raw materials, improving the purity and quality of the raw materials, and making the performance of the final product more stable and reliable. At the same time, the secondary screening mechanism can perform more precise screening according to different particle size requirements, ensuring that the particle size distribution of the raw materials meets the specific needs of casting processing, which helps to improve the dimensional accuracy and surface quality of the castings.

[0036] The second embodiment differs from the first embodiment in that: the dust extraction assembly 9 includes a connecting frame 91, which is disposed on one side of the screening box 1. A dust extraction box 92 is fixedly installed on the outer wall of the connecting frame 91. An inspection door 95 is hinged to the outer wall of the dust extraction box 92 for internal maintenance. A filter plate 94 is provided on the outer wall of the inspection door 95 for filtering dust and impurities in the air. A drive assembly B93 is fixedly installed at the top of the dust extraction box 92 for providing kinetic energy to the dust extraction fan 96. The output end of the drive assembly B93 is fixedly connected to the dust extraction fan 96 for exhausting dust.

[0037] The raw material particle size screening device for casting processing is equipped with a dust extraction component 9. The dust extraction component 9 controls the dust within a certain range, reduces the dust concentration in the workshop, makes the working environment cleaner, reduces the irritation and damage of dust to the respiratory tract and skin of operators, helps to protect the health of operators, and improves the comfort and safety of work.

[0038] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0039] When the equipment is in use, the raw materials for casting are first conveyed to the screening box 1 through the conveying hopper 2, and then fall onto the vibrating screen B811 by gravity. As the raw materials generate dust as they fall, the drive component B93 is activated via the control panel 4. The drive component B93 drives the dust extraction fan 96, which sends the dust-laden air from the screening box 1 into the dust extraction box 92. After being filtered by the air filter plate 94, the dust and impurities in the air are trapped in the dust extraction box 92, while clean air is discharged. After a period of retention, the inspection door 95 can be opened to centrally clean the dust and impurities in the dust extraction box 92. After the raw materials fall onto the vibrating screen B811, the hydraulic rod 88 extends and retracts, causing the vibrating screens A89 and B811 to move. The vibrating screen B811 performs a first-stage screening, and the raw materials that fall through the screen undergo a second screening via the vibrating screen A89. The selected raw materials fall through the vibrating screen A89 and are conveyed to the collection box 11 for collection via the drop plate 10. The larger particles on the screen plate are screened for a period of time. The drive assembly A82 is started through the control panel 4. The operation of the drive assembly A82 drives the threaded rod 862 and gear B to rotate, which in turn drives the gate body 812, which is engaged with its outer wall, to slide in the slide plate 83. As the gate body 812 slides open, the rotation of the threaded rod 862 drives the movable connecting seat 864 to move on the threaded rod 862 and the limit slide rail 863. The movement of the movable connecting seat 864 drives the connecting shaft A866 to move, which in turn drives the cleaning plate A865 and cleaning plate B868 connected by the connecting assembly 867 to clean the larger particles on the vibrating screen B811 and vibrating screen A89. The larger particles are then cleaned through the discharge plate 5 and sent to the receiving box 7 for centralized processing.
