Description

Technical Field

[0001] The utility model belongs to the technical field of brick production, and in particular relates to an air suction top peeling device for autoclaved aerated concrete blocks. Background Art

[0002] Steam-pressurized concrete blocks are made of fly ash as the main raw material, with a foaming agent added, water added and stirred, and voids formed by chemical reaction. The blocks are then cast, pre-cured and cut, and autoclaved to form a silicate building material with a highly dispersed porous structure. The material has good sound insulation and heat insulation properties, and is light and earthquake-resistant, making it a high-quality wall material. The production process of autoclaved aerated concrete blocks includes water addition and stirring, casting and molding, gas expansion, cutting and peeling, and autoclaving. Cutting and peeling means that after the concrete blocks are formed, the large blocks need to be cut into the required size. During the cutting process of the concrete blocks, the cutting unit needs to be used to peel the blank to ensure that the product surface is smooth and without defects. At present, when concrete blocks are peeled, the lifting mechanism is mainly used to drive the suction hood to process the top surface. When in use, the translation mechanism is used to drive the roller to roll and brush the top surface. When the roller is working, the suction fan sucks air, and the suction hood can absorb the top surface brushed by the roller. During the use of the above-mentioned adsorption device, the roller cannot completely brush the top surface, resulting in incomplete cleaning and absorption of the top surface; secondly, the width of the roller peeling treatment is fixed, and the use limitation is poor, which cannot meet the peeling requirements of concrete blocks of different widths. Therefore, it is an objective need to develop an air suction top peeling device for autoclaved aerated concrete blocks with a reasonable structure, clean and thorough peeling treatment, and improved use requirements. Summary of the invention

[0003] The utility model aims to provide an autoclaved aerated concrete block air suction top peeling device which has a reasonable structure, can perform clean and thorough peeling and can improve the use demand.

[0004] The purpose of the utility model is achieved in this way, including a ditch, a support frame, a lifting mechanism and a top adsorption mechanism, the top adsorption mechanism includes an air suction hood and an adsorption filter installed on the lower side of the air suction hood, the air suction hood is connected and fixed to the lifting mechanism, a plurality of telescopic tubes connected thereto are evenly installed on the top of the air suction hood, a plurality of suction fans are installed on the top of the support frame, the upper ends of the telescopic tubes are connected to the corresponding suction fans through connecting elbows, a muffler is installed under each suction fan, a translation drive assembly is installed in the air suction hood below the adsorption filter, a scraping assembly is detachably installed on the translation drive assembly, the scraping assembly includes a scraping support and a plurality of scraping cutters equidistantly installed on the scraping support, and the scraping cutters are detachably installed in the scraping support.

[0005] Compared with the existing technology, the advantages of this device are: first, multiple suction mechanisms are reasonably arranged on the suction hood, which can increase the suction range and suction force of the suction hood and enhance the adsorption effect on the top skin; second, the structure of the scraping component is optimized, and the scraping component adopts a translation drive mechanism to drive the translation.

DETAILED DESCRIPTION

[0013] The present invention is further described below in conjunction with the accompanying drawings, but the present invention is not limited in any way. Any changes or improvements made based on the teachings of the present invention belong to the protection scope of the present invention.

[0014] Figures 1 to 6As shown, the utility model includes a trench 1, a support frame 2, a lifting mechanism 3 and a top adsorption mechanism. The trench 1 is equipped with a corresponding track structure to facilitate the transfer of the trolley to deliver the concrete blocks to the bottom of the top adsorption mechanism. The lifting mechanism 3 can adopt the pneumatic cylinder or hydraulic cylinder structure used in the prior art. The finished product can be directly purchased according to the stroke and pressure used. The top adsorption mechanism includes an air suction hood 4 and an adsorption filter 5 installed on the lower side of the air suction hood 4. The air suction hood 4 is connected and fixed to the lifting mechanism 3. A plurality of telescopic pipes 6 connected thereto are evenly installed on the top of the support frame 2. A plurality of air suction hoods are installed on the top of the support frame 2. Machine 7, the suction fan 7 is a structure used in the prior art, and the purchase cost is directly reduced according to the power size used. The upper end of the telescopic tube 6 is connected to the corresponding suction fan 7 through a connecting elbow, and a muffler is installed under each suction fan 7. The muffler is a structure used in the prior art. The muffler can reduce the noise generated by the suction fan 7. A translation drive assembly is installed in the suction hood 4 below the adsorption filter 5, and a scraping assembly is detachably installed on the translation drive assembly. The scraping assembly includes a scraping support 8 and a plurality of scraping tools 9 equidistantly installed on the scraping support 8, and the scraping tool 9 is detachably installed in the scraping support 8.

[0015] During the working process of the utility model, the concrete block whose top skin needs to be removed is transferred to the bottom of the suction cover 4 by the transfer trolley. At this time, the lifting mechanism 3 drives the suction cover 4 to move downward. When it moves downward to cover the top of the concrete block, the suction fan 7 is turned on, and the translation drive component is used to drive the scraper component to move along the top of the concrete block. The scraper tool 9 can scrape the top skin of the concrete block during the movement. The scraped top skin will be adsorbed on the adsorption filter under the suction force of the suction fan 7. On the net 5, when the scraping tool 9 has scraped the top skin of the concrete, the translation drive mechanism drives the scraper assembly to return to its original position, the lifting mechanism 3 drives the suction hood 4 to move up to the top of the concrete block, and the transfer trolley moves the concrete block out from under the suction hood, and then another transfer trolley is used to send the recovery trough to the bottom of the suction hood 4, turn off the suction fan 7, the suction force of the adsorption filter 5 disappears, and the top skin adsorbed on the adsorption filter 5 will automatically fall into the recovery trough, completing the peeling of the concrete top skin. The utility model adopts a translational drive mechanism to drive the scraping tool 9 to translate. Relying on the driving force of the translational drive component, the scraping tool 9 can evenly and thoroughly scrape the top skin of the block, and adsorb the scraped top on the adsorption filter 5 through the suction force of the suction hood 4 to ensure that the top skin of the concrete block is cleanly and thoroughly peeled. At the same time, the scraping tool 9 adopts a plurality of structural arrangements, so that different numbers of scraping tools 9 can be installed according to the width of the concrete block to meet the needs of scraping the top skin of concrete blocks of different widths, effectively improving the applicability of the device.

[0016] Furthermore, the translation drive assembly includes a drive motor 10, a first screw 11 and a second screw 12. The drive motor 10 is a structure used in the prior art and can be directly purchased as a finished product according to the power used. The first screw 11 and the second screw 12 are installed on the air suction hood 4 in parallel with each other. The first screw 11 and the second screw 12 are arranged along the length direction of the air suction hood 4. The drive motor 10 is installed on the outside of the air suction hood 4 and is transmission-connected to one end of the first screw 11. A driving pulley 13 is installed at the other end of the first screw 11, and a driven pulley corresponding to the driving pulley 13 is installed at the end of the second screw 12. Wheel 14, a transmission belt 15 is installed between the active pulley 13 and the driven pulley 14, two sliders 16 are respectively installed on the first screw 11 and the second screw 12, and the scraping support 8 is detachably installed between the two sliders 16. When the scraping tool 9 performs peeling, the driving motor 10 drives the first screw 11 and the active pulley 13 to rotate. During the rotation of the active pulley 13, the driven pulley 14 and the second screw 12 are driven to rotate synchronously. During the rotation of the first screw 11 and the second screw 12, they can drive the slider 16 to move on the first screw 11 and the second screw 12, thereby driving the scraping assembly to move.

[0017] In order to further improve the application scope of the device, a first connecting plate 17 is installed on the top of the slider 16, and a first connecting hole is processed on the first connecting plate 17. Second connecting plates 18 are installed at both ends of the scraper support 8, and a plurality of second connecting holes are evenly spaced above and below the upper part of the second connecting plate 18. The first connecting hole is coaxially connected to the corresponding second connecting hole with a first bolt, and the first bolt is fixed by a nut. After the suction 4 is moved down and covered on the concrete block through the lifting mechanism 3, the installation height of the scraper support 8 on the slider 16 can be adjusted by the second connecting plate 18, thereby adjusting the distance between the scraper tool 9 and the top skin of the concrete, and then adjusting the peeling thickness of the scraper tool 9, thereby improving the applicability of the device.

[0018] Furthermore, in order to improve the convenience of installation and replacement of the scraper tool 9, a tool mounting groove 81 is processed at the lower center of the scraper support 8 along its length direction, and multiple positioning holes are processed at equal intervals on both sides of the tool mounting groove 81 along its length direction. The multiple scraper tools are the same size, and multiple scraper tools are processed with mounting holes corresponding to the positioning holes. The upper part of the scraper tool 9 is located in the tool mounting groove 81, and a second bolt is coaxially installed in the positioning hole and the mounting hole. The second bolt is connected and fixed by a nut. The overall peeling width of the scraper tool 9 is adjusted by changing the number of scraper tools 9 to meet the peeling requirements of the top skin of concrete blocks of different widths. When some areas on the scraper tool 9 are severely worn, the severely worn scraper tool 9 can be directly removed and replaced with a new scraper tool 9, thereby saving replacement costs and achieving the effect of simple and quick operation.

[0019] Furthermore, a limiting plate 82 is installed in the tool mounting groove 81 along its length direction, and a limiting hole coaxial with the positioning hole is processed on the limiting plate 82. A limiting slot 91 is processed on the upper part of the scraping tool 9, and the limiting slot 91 is clamped on the limiting plate 82. When the scraping tool 9 is inserted into the limiting plate 82, the connection stability between the scraping tool 9 and the scraping support 8 can be improved. The lower part of the scraping tool 9 is set to be wide at the top and narrow at the bottom, so that the top skin on the concrete block can be scraped up smoothly, and at the same time, it can prevent the scraped top skin from being difficult to pile up.

[0020] Furthermore, the cross-sectional shape of the lower portion of the limiting plate 82 is a trapezoidal arrangement. When the scraping tool 9 is placed into the tool installation groove 81, the scraping tool 9 can be smoothly plugged into the limiting plate 82, thereby improving the installation efficiency of the scraping tool 9.

[0021] Furthermore, in order to improve the connection stability between two adjacent scraping tools 9 and ensure that multiple scraping tools 9 are always in a straight line during the scraping process, a positioning bar 92 is vertically provided on one side of the scraping tool 9, and a positioning groove 93 is vertically provided on the other side of the scraping tool 9. The positioning groove 93 and the positioning bar 92 are symmetrically arranged, and the positioning bars 92 and the positioning grooves 93 of the two adjacent scraping tools 9 are slidingly matched and connected.

[0022] Furthermore, in order to ensure the stability of the air suction hood 4 during the up and down movement, multiple guide rods 19 are vertically installed on the top of the air suction hood 4, and multiple guide holes matching the guide rods 19 are provided on the support frame 2. The upper ends of the guide rods 19 are slidably installed in the guide holes, and a limiting block is installed at the upper end of the guide rods 19. The guide rods 19 have a guiding function, and the guide rods 19 can ensure that the air suction hood 4 is always in a vertical movement state during the up and down movement.

[0023] Furthermore, in order to ensure that the air suction hood 4 moves upward smoothly and steadily, a slide rail 20 is vertically installed on the inner side of the support column of the support frame 2, and a pulley matching the slide rail 20 is provided on the outer side of the air suction hood 4. The pulley is slidably installed on the slide rail 20, and the pulley drives the air suction hood 4 to move up and down along the slide rail 20, which can improve the smoothness of the up and down movement of the air suction hood 4.
