Description

Technical Field

[0001] This utility model relates to the field of brick blank forming, and in particular to a brick blank forming machine for magnesia-carbon bricks. Background Technology

[0002] Magnesia-carbon bricks are non-burning composite refractory materials made from high-melting-point alkaline oxide magnesium oxide and high-melting-point carbon materials that are difficult to be wetted by slag, with the addition of various non-oxide additives and carbonaceous binders. Magnesia-carbon bricks are mainly used in the lining of converters, AC electric arc furnaces, DC electric arc furnaces, slag lines of ladles, etc. The production process of magnesia-carbon bricks requires the use of brick forming machines.

[0003] A search revealed a Chinese patent publication number CN221604671U, which discloses a brick blank forming machine for magnesia-carbon brick production. This patent includes a processing table, a conveying plate on the processing table via a conveying mechanism, a forming component on the conveying plate via an adjusting component, and a pressing component matching the forming component on the processing table. The conveying plate also has a cleaning and collection mechanism matching the pressing component. This device allows for timely cleaning and collection of raw materials adhering to the surface after the pressing component has been used. This avoids affecting the next processing and prevents the material from adhering to the surface and affecting the flatness of the next pressing. Furthermore, it allows for the collection of raw materials for easy recycling and reuse. However, in current magnesia-carbon brick blank forming machines and devices, residue accumulates in the gaps between multiple pressing components during multiple brick blank forming operations. This residue is difficult to clean and collect, affecting the forming quality and production efficiency. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1 — Figure 6 As shown, a brick blank forming machine for magnesia-carbon bricks includes a base plate 101, a mounting frame 102 bolted to the base plate 101, a linear guide rail assembly 103 mounted on the base plate 101, a forming mechanism mounted on the mounting frame 102, the forming mechanism including a hydraulic cylinder 201 bolted to the top of the mounting frame 102, a lower pressure plate 202 bolted to the output end of the hydraulic cylinder 201, and several pressure blocks 203 bolted to the bottom of the lower pressure plate 202. A moving mechanism is movably mounted on the linear guide rail assembly 103, the moving mechanism including a moving seat 301, a brick blank mold sleeve 302 mounted on the moving seat 301, and a collecting mechanism including a collecting box 401. A cleaning assembly is installed on the 01, which includes a lifting sleeve 403. A roller brush 405 and its power assembly are rotatably mounted on the lifting sleeve 403. The power assembly is an electric motor 404, which is bolted to one side of the lifting sleeve 403. The output end of the electric motor 404 is connected to the roller brush 405 through a coupling. The lifting sleeve 403 is slidably connected to the collection box 401. A guide mechanism is provided on the lower pressure plate 202. The guide mechanism includes two symmetrically arranged guide plates 501, which are bolted to both sides of the lower pressure plate 202. A sliding groove 502 is provided on the guide plate 501. The sliding groove 502 is used to guide the lifting sleeve 403 and the roller brush 405 to move up and down, so that the roller brush 405 can thoroughly clean the pressure block 203.

[0026] In this embodiment, connecting plates 406 are bolted to both sides of the lifting sleeve 403, and a guide shaft 407 is bolted to the top of the connecting plate 406. The guide shaft 407 cooperates with the slide groove 502. The slide groove 502 includes a lifting section 503 and a wave section 504. The lifting section 503 and the wave section 504 are interconnected, and the lifting section 503 is located at both ends of the wave section 504. When the pressure block 203 presses and shapes the magnesia-carbon brick raw material in the brick blank mold sleeve 302, the hydraulic cylinder 201 drives the lower pressure plate 202 and the pressure block 203 to lift, so that the lifting... The end of the lifting section 503 is aligned with the guide shaft 407. As the moving seat 301 moves, the guide shaft 407 enters the slide groove 502 from one end of the lifting section 503. The guide shaft 407 slides in the slide groove 502 along the direction of the lifting section 503 and the wave section 504. The guide shaft 407 drives the lifting sleeve 403 to move up and down through the connecting plate 406. The lifting sleeve 403 drives the rotating roller brush 405 to move along the surface of each pressure block 203, which can thoroughly clean all sides of the pressure block 203 and effectively clean the residue in dead corners and gaps.

[0027] In this embodiment, an inclined plate 409 is bolted inside the lifting sleeve 403, and a closed door 402 is hinged on the collection box 401. The closed door 402 is located inside the collection box 401 on the side away from the inclined plate 409. The inclined plate 409 moves synchronously with the lifting sleeve 403. When the inclined plate 409 moves up and down, it stirs up the debris inside the collection box 401, causing it to accumulate as much as possible at the position of the closed door 402, making it convenient for staff to open the closed door 402 to clean and collect the debris.

[0028] In this embodiment, protective plates 408 are welded to both sides of the top of the lifting sleeve 403. The protective plates 408 prevent debris cleaned off the pressure block 203 from falling onto the outside of the lifting sleeve 403.

[0029] In this embodiment, a plurality of electric push rods 303 are fixedly installed on the movable base 301. The output end of the electric push rod 303 is connected to a movable rod 304 by bolts. The movable rod 304 is connected to the brick blank mold sleeve 302 by bolts. A plurality of ventilation holes 305 are provided on the side of the brick blank mold sleeve 302. The arrangement of the electric push rods 303 and the movable rod 304 facilitates the demolding of the brick blank mold sleeve 302.

[0030] Working principle: When using this device, the magnesia-carbon brick raw material is put into the brick blank mold sleeve 302. The linear guide rail assembly 103 is activated, which drives the moving seat 301 to move below the mounting frame 102, aligning the brick blank mold sleeve 302 with the pressure block 203. The hydraulic cylinder 201 is activated, pushing the lower pressure plate 202 and the pressure block 203 downwards. The pressure block 203 enters the brick blank mold sleeve 302 to press and shape the magnesia-carbon brick raw material. After pressing, the output end of the hydraulic cylinder 201 retracts, aligning the end of the lifting section 503 of the slide groove 502 on the guide plate 501 with the guide shaft 407. The linear guide rail assembly 103 is then controlled to drive the moving seat 301 to move. As the moving seat 301 moves, the guide shaft 407 moves from one end of the lifting section 503... The end enters the chute 502, and the guide shaft 407 slides in the chute 502 along the direction of the lifting section 503 and the wave section 504. The guide shaft 407 drives the lifting sleeve 403 to move up and down through the connecting plate 406. The lifting sleeve 403 drives the rotating roller brush 405 to move along the surface of each pressing block 203, which can thoroughly clean all sides of the pressing block 203 and effectively clean the residue in dead corners and gaps. At the same time, the inclined plate 409 in the lifting sleeve 403 moves synchronously with the lifting sleeve 403. When the inclined plate 409 moves up and down, it blows the debris in the collection box 401, so that the debris is piled up as close as possible to the closed door 402. After the molding operation is completed, it is convenient for the staff to open the closed door 402 to clean and collect the debris.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
