[0002] In the production process of aerated concrete blocks, fly ash is usually used as the main raw material. The quality of fly ash directly affects the performance of the product. Unburned coal particles, metal fragments or other large particles will affect the quality of aerated concrete blocks. Therefore, it is necessary to remove the slag from the fly ash before production.

[0003] Currently, the removal of fly ash from aerated concrete blocks mainly relies on screening equipment. However, some slag is metallic, so magnets are needed for adsorption. The current adsorption equipment mainly relies on electromagnets. However, after a period of adsorption, the electromagnets need to be replaced to clean the adsorbed material, which requires machine shutdown and affects production efficiency. Summary of the Invention

[0018] The present invention will now be clearly described in conjunction with the accompanying drawings and embodiments:

[0019] like Figure 1-4As shown, the aerated concrete block fly ash removal device includes a ash removal machine housing 1, which is a rectangular hollow shell welded from Q235 steel, possessing sufficient structural strength and sealing performance. An inclined ash removal channel 2 is installed inside the ash removal machine housing 1, with the left side higher than the right. The inner wall of the channel is lined with a wear-resistant ceramic layer to extend its service life. A vibrating motor 3 is installed on the ash removal machine housing 1, generating high-frequency vibration through an eccentric block. A vibrating screen plate 4 is installed inside the ash removal channel, dividing the ash removal channel 2 into upper and lower chambers, effectively removing large particles of impurities. A discharge channel 5 is located on the lower side of the lower chamber of the ash removal channel 2, featuring an inclined design to ensure smooth material discharge. A feed hopper is located at the higher end of the ash removal channel 2 for easy connection to upstream conveying equipment.

[0020] The top of the slag removal housing 1 is equipped with a slag removal adsorption component 6. This component adopts a modular design for easy maintenance. The slag removal adsorption component 6 includes a rotating groove 61. The top surface of the slag removal housing 1 has a rotating groove 61 extending from the feed hopper to the bottom. Except for the feed hopper, the top surface of the slag removal housing 1 is entirely occupied by the rotating groove 61. The rotating groove 61 is a rectangular through groove. The left and right ends of the groove wall are symmetrically provided with mounting holes 62. Copper-based self-lubricating bearings are installed in the holes. Each mounting hole 62 is provided with a rotating pin 63. The surface of the rotating pin 63 is quenched to improve wear resistance. The left and right rotating pins 63 are connected by a rotating plate 64 to form a stable rotating support structure. The rotating plate 64 can rotate up and down in the rotating groove. Specifically, the end of the rotating pin 63 is connected to a rotating rod 68. The rod body is marked with angle scales. The rotating rod 68 is equipped with a rotating handwheel 69, the surface of which is covered with an anti-slip rubber layer. The rotating plate 64 is a rectangular plate with a thickness of 20mm to ensure structural rigidity. The two ends of the rotating plate 64 are fixed to a pair of rotating pins 63 by key connection to ensure reliable torque transmission.

[0021] The rotating plate 64 has disassembly slots on its upper and lower sides, each slot housing an adsorption plate 65. The adsorption plates 65 are fixed in the slots by positioning pins, etc., and are made of aluminum alloy to reduce weight. An electromagnet 66 is installed inside the adsorption plate 65, operating at DC 220V. The electromagnet 66 and the adsorption plate 65 form a two-sided magnetic adsorption device, allowing slag in the coal ash to be adsorbed onto the adsorption plate 65 under magnetic force. A cleaner 67 is provided for each adsorption plate 65. When the corresponding adsorption plate 65 rotates to the upward position, the cleaner 67 automatically cleans the adsorption surface.

[0022] The cleaner 67 includes a pair of cleaning plates 671, respectively disposed on the front and rear side walls of the disassembly slot. The cleaning plates 671 extend laterally and are made of polyurethane material to avoid scratching the surface of the electromagnet 66. Symmetrically arranged on both sides of the cleaning plates 671 are left-right extending sliding grooves 672. Sliding blocks are slidably mounted on the sliding grooves 672 to ensure smooth sliding. A sliding rod 673 connects the sliding blocks. The rod surface is chrome-plated. A scraper 674 is mounted on the lower side of the sliding rod 673. The scraper 674 is made of wear-resistant silicone rubber and maintains a contact pressure of 0.5mm with the disassembly plate. That is, the scraper 674 is located approximately 0.5mm above the adsorption plate 65.

[0023] Preferably, a row of telescopic rods 675 is provided on the lower side of the sliding rod 673, and a return spring 676 is sleeved on the telescopic rod 675. The spring preload is adjustable, and the telescopic end of the telescopic rod 675 is connected to the scraper 674 to ensure uniform contact.

[0024] A dual electromagnet structure with rotatable switching and an online cleaning mechanism were designed. The coal ash raw material is first classified by particle size through the vibrating screen plate 4, and then flows through the adsorption area of ​​the electromagnet 66. When one electromagnet 66 is saturated, the standby electromagnet 66 is switched to work by rotating the handwheel 69 180°. At the same time, the cleaner 67 is started to scrape and clean the saturated electromagnet 66. The scraper 674 maintains constant pressure under the action of the telescopic rod 675. The whole process does not require stopping the machine and realizes continuous production.
