DETAILED DESCRIPTION

[0030] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0031] Example one:

[0032] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 7 , a raw material mixing device for non-clay sintered perforated brick production, comprising a base plate 10, a stirring barrel 11 is arranged above the base plate 10, a crushing barrel 12 is arranged above the stirring barrel 11, two first crushing rollers 24 are rotatably arranged inside the crushing barrel 12, a plurality of crushing protrusions 25 are arranged on the outer cylindrical surface of each first crushing roller 24, a second motor 32 is arranged on one side of each first crushing roller 24 outside the outer sidewall of the crushing barrel 12, the output end of each second motor 32 is fixedly connected with the sidewall of the first crushing roller 24 adjacent thereto through the crushing barrel 12, the second motor 32 is a general motor, which is prior art, two second crushing rollers 26 are slidably arranged inside the crushing barrel 12 between the two first crushing rollers 24, an elastic sealing element 27 is arranged inside the crushing barrel 12 between the two second crushing rollers 26, the two sidewalls at the lower end of the elastic sealing element 27 are abuttingly connected with the outer cylindrical surfaces of the second crushing rollers 26 adjacent thereto, a stirring assembly is arranged inside the stirring barrel 11, and a discharge assembly is arranged on the lower end surface of the stirring barrel 11.

[0033] Specifically, the output end of the second motor 32 drives the first crushing roller 24 to rotate, and the first crushing roller 24 will crush the porous brick raw materials between the first crushing roller 24 and the second crushing roller 26 when rotating, and the second crushing roller 26 will rotate in the opposite direction of the first crushing roller 24 during the crushing process. Through the arrangement of the plurality of crushing protrusions 25 on the first crushing roller 24, the crushing effect of the first crushing roller 24 on the porous brick raw materials can be effectively improved.

[0034] The top two ends of the elastic sealing piece 27 are fixedly connected with the inner side wall of the crushing cylinder 12, and the whole elastic sealing piece 27 is as shown in the accompanying drawings. Figure 7 As shown: It is conical as a whole, is formed by bending a plate, the top is a sharp head, and the bottom is an open shape. Therefore, the wall surface on both sides of the opening of the elastic sealing piece 27 can form elastic deformation of the elastic sealing piece 27 cone, and the side walls of the elastic sealing piece 27 on both sides of the bottom abut against the outer circular surface of the second crushing roller 26 to form an arc surface. Therefore, when the first crushing roller 24 and the second crushing roller 26 rotate and crush the porous brick raw materials, the lower end side wall of the elastic sealing piece 27 can simultaneously scrape the outer circular surface of the second crushing roller 26, thereby effectively preventing too much raw material from adhering to the outer circular surface of the second crushing roller 26, ensuring the crushing effect of the whole device. At the same time, the elastic sealing piece 27 can also form a sealing effect between the two second crushing rollers 26, effectively preventing the uncrushed porous brick raw materials from falling directly from between the two second crushing rollers 26 to the inside of the stirring cylinder 11, thereby reducing the production quality of the porous brick. Moreover, the top of the elastic sealing piece 27 is in the shape of a sharp head, which can divide the porous brick raw materials poured into the inside of the crushing cylinder 12, avoid the accumulation of the porous brick raw materials in the inside of the crushing cylinder 12, and effectively improve the processing efficiency of the device.

[0035] Further, as shown in the accompanying drawings, Figure 4 and Figure 5 The stirring assembly comprises a rotating shaft 13 rotatingly arranged in the inside of the stirring cylinder 11, and a first motor 23 arranged between the base plate 10 and the stirring cylinder 11 at the lower end surface of the stirring cylinder 11. The output end of the first motor 23 is fixedly connected with the lower end surface of the rotating shaft 13 through the stirring cylinder 11. The first motor 23 is a common motor, which is a prior art. A plurality of transverse scrapers 14 are arranged on the outer circular surface of the rotating shaft 13 at the bottom of the stirring cylinder 11. The upper end surface of each transverse scraper 14 is provided with a vertical scraper 15. One side wall of each vertical scraper 15 abuts against and contacts the inner side wall of the stirring cylinder 11. A plurality of connecting rings 16 are connected and arranged between the plurality of vertical scrapers 15. The stirring assembly further comprises a plurality of stirring vanes 17 arranged on the outer side wall of the rotating shaft 13.

[0036] Specifically, the output end of the first motor 23 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the horizontal scraper 14, the vertical scraper 15, and the stirring fan blade 17 and other components to rotate. In this process, the plurality of horizontal scrapers 14 scrape the inner bottom surface of the stirring drum 11, and the plurality of vertical scrapers 15 scrape the inner side wall of the stirring drum 11, which can effectively prevent excessive raw materials from adhering to the inner wall of the stirring drum 11, causing uneven mixing of the overall raw materials. At the same time, the rotation of the plurality of stirring fan blades 17 can effectively mix and stir the perforated brick raw materials, and the plurality of stirring fan blades 17 are arranged in layers to form layered stirring of the perforated brick raw materials in the stirring drum 11, further improving the stirring effect of the plurality of stirring fan blades 17 on the raw materials and improving the production quality of the perforated bricks.

[0037] Further, as shown in Figure 3 and Figure 6 each first crushing roller 24 is provided with a chute 29 on the outer side wall of the crushing drum 12, each chute 29 is slidably provided with a sliding block 30 inside, the inner bottom surface of each chute 29 is provided with a long hole 28, the inside of each long hole 28 is slidably provided with a central rotating shaft 37, one end of each central rotating shaft 37 is fixedly connected with one end of the adjacent second crushing roller 26, the other end of each central rotating shaft 37 is rotatably connected with the adjacent sliding block 30, and each sliding block 30 is provided with a plurality of springs 31 on both sides in the chute 29.

[0038] Specifically, each central rotating shaft 37 is coaxially connected with the adjacent second crushing roller 26, and the plurality of springs 31 on both sides of the sliding block 30 can form elastic support for the sliding block 30. During the crushing process of the perforated brick raw materials by the second crushing roller 26 and the first crushing roller 24, large particles of raw materials may be encountered. At this time, the second crushing roller 26 will drive the sliding block 30 to slide horizontally along the long hole 28 to increase the distance between the first crushing roller 24 and the second crushing roller 26 under the support of the raw materials, and the sliding block 30 will slide in the chute 29 following the elastic sealing member 27, and the plurality of springs 31 at both ends of the sliding block 30 will be stretched and compressed. After the large particles of raw materials are crushed, the sliding block 30, the central rotating shaft 37, and the second crushing roller 26 will return to the original position under the action of the self-elastic tension of the plurality of springs 31, thereby effectively preventing damage to the outer cylindrical surface of the second crushing roller 26 and preventing the phenomenon of material jamming between the first crushing roller 24 and the second crushing roller 26.

[0039] Further, as shown in Figure 1 each first crushing roller 24 is provided with a guide plate 36 inside the crushing drum 12.

[0040] Specifically, the arrangement of the second crushing roller 26 can effectively avoid the accumulation of the raw materials and improve the practicability of the device.

The push cylinder 22 is a common electric push cylinder, a hydraulic push cylinder, etc., which is prior art. The output end of the push cylinder 22 is rotatably connected with the lower end surface of the sealing rotating plate 19.

[0042] Specifically, the two baffles 20 not only form a support between the base plate 10 and the stirring drum 11, but also cooperate with the sealing rotating plate 19 to form a partition on both sides of the sealing rotating plate 19 when the perforated brick raw materials are discharged from the discharge port 18, preventing the raw materials from falling onto the end surface of the base plate 10. The output end of the push cylinder 22 forms a support for the lower end surface of the sealing rotating plate 19, so that the sealing rotating plate 19 can form a closing and opening of the discharge port 18. The protrusions arranged above the sealing rotating plate 19 are just engaged with the discharge port 18, so that the upper end surface of the sealing rotating plate 19 and the inner ground surface of the stirring drum 11 form a plane.

[0043] Further, as shown in Figure 1 the stirring drum 11 and the base plate 10 are connected and arranged with a plurality of second reinforcing rods 35, and the crushing drum 12 and the stirring drum 11 are connected and arranged with a plurality of first reinforcing rods 34,

[0044] Specifically, the arrangement of the first reinforcing rod 34 and the second reinforcing rod 35 plays a supporting role for the stirring drum 11 and the crushing drum 12, and improves the overall stability of the device.

[0045] Further, as shown in Figure 1 and Figure 2 the outer inclined wall of the crushing drum 12 is arranged with a vibrator 33.

[0046] Specifically, the vibrator 33 is a common vibrator, which is prior art. The arrangement of the vibrator 33 can effectively avoid the accumulation of the crushed raw materials on the inner inclined wall of the crushing drum 12 during the discharge of the crushing drum 12.

[0047] Firstly, start all the first motor 23 and the second motor 32, pour the porous brick raw material into the inside of the crushing cylinder 12, the output end of the second motor 32 drives the first crushing roller 24 to rotate, the first crushing roller 24 combines the second crushing roller 26 to form the crushing of the porous brick raw material, and the elastic sealing element 27 forms the scraping treatment of the outer surface of the second crushing roller 26 in the process.

[0048] Then, the crushed raw material falls from the crushing cylinder 12 to the inside of the stirring cylinder 11, at this time the output end of the first motor 23 drives the rotating shaft 13 to rotate, the rotating shaft 13 drives the plurality of horizontal scrapers 14 and vertical scrapers 15 and stirring blades 17 to rotate, the plurality of horizontal scrapers 14 and vertical scrapers 15 form the scraping treatment of the inner wall of the stirring cylinder 11 and the stirring of the raw material in the stirring cylinder 11, and the plurality of stirring blades 17 form the multi-layer stirring of the raw material in the stirring cylinder 11.

[0049] Finally, start the push cylinder 22, the output end of the push cylinder 22 drives the sealing rotating plate 19 to rotate along the rotating connection between the sealing rotating plate 19 and the baffle 20, so that the discharge port 18 is opened, and the raw material in the stirring cylinder 11 is discharged from the discharge port 18 under the rotation of the stirring assembly.
