Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of solid waste treatment, and particularly relates to a crushing device for preparing calcium aluminate powder from aluminum ash. BACKGROUND

[0002] In recent years, aluminum ash is a solid waste generated in the production process of the aluminum industry, rich in metal aluminum and aluminum oxide and other components, and its recycling has important significance for resource recycling and environmental protection. Calcium aluminate powder, as an important refractory material and chemical raw material, can be prepared by secondary processing of aluminum ash. The crushing device directly affects the particle size distribution of aluminum ash and the efficiency of subsequent reactions as a key equipment.

[0033] Embodiments

[0034] Reference Figures 1-6 For the embodiments of the present application, the embodiments provide a crushing device for preparing calcium aluminate powder from aluminum ash, comprising,

[0035] The bearing mechanism 100 comprises a bearing frame 110, a crushing assembly 120 arranged on the top of the bearing frame 110 for crushing solid waste, and a feed hopper 130 fixedly installed on the top of the crushing assembly 120;

[0036] The separating and collecting mechanism 200 comprises a box 210 fixedly installed in the inner cavity of the bearing frame 110, a driving assembly 220 arranged on the outer side of the box 210, a sorting assembly 230 arranged in the inner cavity of the box 210 for processing iron filings, and a reciprocating assembly 240 used in cooperation with the driving assembly 220;

[0040] The screening cylinder 234 supported by the cylinder rod 231 reciprocally swings under the action of the reset spring rod 232 and the rotating shaft 233, and the centrifugal force is used to realize the preliminary separation of aluminum ash and iron filings. The cooperation of the electromagnetic scraper 237 and the collection groove 238 further improves the collection efficiency of the iron filings. The separation net 239 ensures that the iron filings are completely separated from the materials. The design of the filter bag 236 facilitates regular cleaning and replacement. The separation net 239 can completely separate the collected iron filings from the aluminum ash, avoiding cross contamination during manual sorting.

[0041] Further, the driving assembly 220 comprises a bracket 221 fixedly mounted at the outer side of the box body 210, a limiting cylinder 222 fixedly mounted at the top of the bracket 221, a support rod 223 fixedly mounted at the outer side of the box body 210, a servo motor 224 fixedly mounted at the outer side of the support rod 223, and a connecting rod 225 fixedly mounted at the output end of the servo motor 224.

The reciprocating assembly 240 further comprises a reciprocating groove rod 245 fixedly installed outside the limiting shaft 244, a limiting sliding block 246 movably clamped at the groove of the reciprocating groove rod 245, and a support column 247 rotatably installed outside the reciprocating groove rod 245.

[0044] Wherein, the shaft 241 and the swing piece 242 convert rotary motion into reciprocating motion, the support column 243 and the limiting shaft 244 provide stable support and guidance, the cooperation of the reciprocating groove rod 245 and the limiting sliding block 246 ensures accurate control of the motion trajectory, and the damping design of the support column 247 effectively buffers vibration, so that the whole reciprocating system runs smoothly and reliably, providing a guarantee for the efficient work of the screening cylinder 234.

[0045] Further, the top of the cylinder rod 231 is fixedly sleeved outside the support column 247 through a damping member, the number of the cylinder rods 231 is three, and they are uniformly distributed outside the support column 247.

The slot 235 is conical, and the outer edge of the slot 235 is in the shape of outward expansion.

[0046] Wherein, the screening cylinder 234 is designed with an inclined surface and a conical slot 235, which takes advantage of the density difference between aluminum ash and iron filings to make iron filings preferentially gather in the slot 235 under the action of centrifugal force. The electromagnetic scraper 237 adsorbs iron filings when the screening cylinder 234 swings, and concentrates and recycles them through the collecting groove 238, avoiding the secondary mixing of iron filings into the material. The hinged structure of the reset spring rod 232 and the rotating shaft 233 makes the screening cylinder 234 automatically shake off the adhered fine powder in reciprocating swing, preventing the screen from being blocked.

The output end of the driving motor 124 is fixedly connected with the end of the driving toothed roller 122, and the teeth of the driving toothed roller 122 are in meshing engagement with the driven toothed roller 123.

[0048] Wherein, the design of the driving toothed roller 122 and the driven toothed roller 123 in meshing engagement realizes efficient crushing through shear force, effectively avoiding over-pulverization; the design of the driving motor 124 directly connected with the driving toothed roller 122 simplifies the transmission structure and improves the energy conversion efficiency; and the closed structure of the crushing box 121 effectively inhibits dust from escaping, improving the working environment.

[0049] Further, the separation and collection mechanism 200 further comprises a sealing shell 250 fixedly installed on the top of the box body 210, and a sealing box door 260 hingedly installed on the outside of the box body 210.

[0050] The sealing shell 250 and the sealing box door 260 are designed to effectively inhibit dust emission during production, improve the working environment, and facilitate daily maintenance and repair of the equipment. The hinged box door design is easy to operate, the observation window is provided to facilitate real-time monitoring of the internal working conditions, the entire sealing system meets environmental protection requirements, and the risk of environmental pollution during production is reduced.

[0051] In use, the aluminum ash raw material enters the crushing assembly 120 from the feed hopper 130 and is crushed by the meshing of the driving toothed roller 122 and the driven toothed roller 123 and then falls into the separation and collection mechanism 200;

[0052] The servo motor 224 of the driving assembly 220 drives the reciprocating assembly 240 to operate through the connecting rod 225, so that the shaft rod 241 and the reciprocating groove rod 245 drive the screening cylinder 234 to reciprocate, the iron filings are gathered along the inclined surface and the conical notch 235 by centrifugal force, the iron filings are adsorbed to the collection groove 238 and isolated by the isolation net 239, and the aluminum ash falls into the collection below through the filter bag 236;
