Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building material engineering, in particular to a device for uniformly mixing a brick-making combustion-supporting agent from red mud-contaminated soil. BACKGROUND

[0002] Red mud, also known as red mud, is an industrial solid waste discharged after the extraction of alumina from bauxite. During the process of rolling and pressing bricks from red mud-contaminated soil, the prepared multi-waste soil with added combustion-supporting agent is rolled, pressed, and dried to form load-bearing porous bricks or non-load-bearing hollow bricks. Many of them still need to be manually pressed into shape, which is not very efficient. During the mixing process of the soil and the combustion-supporting agent, uneven mixing often occurs, leading to uneven burning during the brick burning process and causing the bricks to bulge. In addition, in the pressing process of existing hollow brick forming devices, to ensure the amount of pressing, the amount of raw materials required for each pressing is generally more than the actual amount required, resulting in waste of raw materials. Moreover, residual material often adheres to the end of the hollow brick cavity, leaving a thin connected material at the end of the cavity, which reduces the quality of the hollow bricks.

[0003] Therefore, the present application provides a device for uniformly mixing a brick-making combustion-supporting agent from red mud-contaminated soil to solve the problems raised in the background. SUMMARY

Detailed Implementation

[0040] Reference Figures 1-8 This invention provides a technical solution: a device for uniformly mixing and preparing a combustion aid for brick making from red mud-contaminated soil, comprising:

[0041] Conveying device 2, type 3, is used to transfer the supporting base plate;

[0042] Conveying device 3 4 is located outside conveying device 2 3 and is used for the reciprocating transfer of the frame template and the unidirectional transfer of the supporting base plate.

[0043] Conveying device 1 2 is located above conveying device 2 3 and is used to transfer the mixed material into the brick forming module composed of the frame template and the supporting base plate.

[0044] Pressing device 5, positioned above conveying device 3 along the conveying direction of conveying device 1 2, is used to hollowly mold the mixture in the brick forming module; and

[0045] Mixing device 1 is located on one side of conveying device 2 and is used for mixing and stirring raw materials and conveying the mixed material to conveying device 2.

[0046] In this embodiment, the mixing device 1 includes:

[0047] The mixing box has parallel partitions 11 inside to form a cavity for the independent holding of raw materials. The cavity is provided with a loosening screw 13, the upper end of which is connected to a rotating shaft 12 rotatably set on the top of the mixing box.

[0048] Belt 14, fitted onto all of the aforementioned pivots 12; and

[0049] The mixing feed cylinder 15 is located at the lower port of the mixing chamber and is used for introducing and mixing raw materials;

[0050] Specifically, the combustion aid and soil materials are added to the diaphragm in an alternating manner. The belt drives the rotating shaft to rotate, which in turn drives the loosening screw to loosen the combustion aid and soil materials in the diaphragm, so that the combustion aid and soil materials can flow steadily and smoothly into the mixing conveyor. In addition, by changing the size of the diaphragm or the number of diaphragms in advance, the stable output of the combustion aid and soil materials can be changed. With the high-frequency operation of the reciprocating telescopic rod, it is beneficial to improve the continuous and uniform mixing effect of the combustion aid and soil materials and ensure high mixing efficiency.

[0051] In this embodiment, the mixing conveyor cylinder 15 includes:

[0052] The mixing cylinder 16 has a feed inlet on its left side partially connected to the mixing box, and a discharge outlet on its right side partially located above the material transfer device 2. A support cylinder 17 is fixed inside the cylinder, and a mixing and material transfer screw 110 is provided in the support cylinder 17. The left end of the mixing and material transfer screw 110 is connected to the rotating shaft 113.

[0053] Arc-blocking plates 18, whose axial width matches the width of the cavity, are arranged in sets of one set every other cavity, occupying half the number of cavities. All the arc-blocking plates 18 are fixed into a single structure by crossbars and are driven to reciprocate by reciprocating telescopic rods 112; and

[0054] The discharge screw cylinder 111 is provided on one side of the discharge port of the mixing cylinder 16 and is sleeved on the outside of the mixing conveyor screw blade 110, and the right end of the discharge screw cylinder 111 is rotatably connected to the right end of the mixing cylinder 16.

[0055] Specifically, the reciprocating telescopic rod is driven at high frequency to move the arc-blocking plate back and forth by a displacement of one unit of cavity width. At the same time, the mixing and conveying screw blades are used to stir and convey the material, so that the combustion aid raw material and soil raw material are mixed evenly in small discharge amounts and conveyed to the discharge port. The setting of the discharge screw cylinder can convey the material while discharging the mixed material, so that the material is evenly filled into the frame template.

[0056] In this embodiment, the rotation direction of the discharge screw cylinder 111 is opposite to the rotation direction of the conveyor screw blade 110.

[0057] In this embodiment, the conveying device 3 4 includes a support 41, which is arranged on both sides of the conveying device 2 3. A transverse moving device 42 is fixed on the upper end of each support 41. A support plate 44 is fixed on the transverse moving seat in the transverse moving device 42. The support plates 44 on the left and right sides support and fix the frame template 43. A vertical pushing rod 45 is also fixed at the lower end of the support plate 44.

[0058] The surrounding template serves as the side enclosure for the mixture, such as... Figure 5 In this embodiment, the frame template is provided with 3×3 independent brick blank mold cavities;

[0059] Specifically, when the supporting base plate moves below the conveying device 2, the lateral movement device drives the support plate 44 and the frame template 43 to move below the conveying device 2. Then, the push rod 45 drives the supporting base plate to press tightly against the lower end face of the frame template 43. After completion, the lateral movement device slowly and uniformly moves to the right (e.g., ...). Figure 1 (Transmission direction) moves, and the conveying device 12 slowly and evenly transmits the mixed material into the frame template. After the material is transmitted, the conveying device 12 stops running, and the transverse device then transmits the frame template to the bottom of the pressing device for pressing. After the pressing is completed, the push rod 145, together with the push rod 353, moves the pressed brick blank and the supporting base plate downward together and falls into the conveying device 12 again for transmission.

[0060] In addition, it is also important to note that, such as Figure 8 As shown, the amount of mixed material filling the frame template needs to be lower than the height of the frame template in order to accommodate the increase in the height of the mixed material before it is pressed when the hollow molding module is running.

[0061] In a preferred embodiment, the distance between the supporting base plate and the lower end face of the frame template is set to 3 / 2 of the height of the frame template, and the distance between the conveying device 2 and the upper end face of the frame template is also set to 3 / 2 of the height of the frame template.

[0062] In this embodiment, the pressing device 5 includes:

[0063] Support 2 51, with a vertical push rod 2 52 installed at the middle of its upper end;

[0064] The upper end of the push rod 53 is fixed in two parallel and spaced collection plates 54. The upper collection plate 54 is connected and fixed to the output end of the push rod 52. A pressing plate 55 is fixed to the lower output end of the push rod 53.

[0065] Hollow forming modules 56 are configured into multiple groups and are respectively assembled on pressing plates 55;

[0066] Specifically, the bottom of the hollow forming module is first driven by the push rod 52 to touch the supporting base plate, and the pressing plate 55 is flush with the upper surface of the frame template, such as... Figure 8 As shown.

[0067] In this embodiment, the hollow forming module 56 includes:

[0068] The push rod 561 is fixed on the lower collection plate 54. A triangular plate 562 is fixed at its lower output end. Side top plates 563 are respectively hinged to both sides of the triangular plate 562. Top roller 564 and warning roller 565 are respectively hinged to the outer end and middle part of the side top plate 563. A reset spring rod 566 is also connected between the two side top plates 563.

[0069] A pressing partition 567 is set on both ends of a triangular plate 562. Its upper end is fixed to a lower collection plate 54. Spring rods 568 are respectively provided on the left and right sides of its side plate. A concave plate 569 is fixed at the lower end of the corresponding spring rods 568 between the two pressing partitions 567. A pressing side plate 5610 is rotatably installed on the concave surface of the concave plate 569. A return torsion spring 5611 is also installed at the rotating end of the pressing side plate 5610 and the concave plate 569.

[0070] Specifically, the push rods extend downwards to move the side top plate downwards, causing it to push against the pressing side plate and rotate outwards, pushing the mixed raw materials to both sides until the pressing side plate is in a vertical position. After this is completed, the push rod 353 drives the pressing plate to press the mixed raw materials. After this is completed, the pressed brick blank and the supporting base plate are moved downwards together by the cooperation of the push rod 353 and the push rod 45, and then sent out into the conveying device 12. The spring rod 568 is set so that during the outward rotation of the pressing side plate, the rotation base point of the pressing side plate moves upwards, so that the pressing side plate can rotate outwards to a vertical position.

[0071] In this embodiment, the upper end of the pressing side plate 5610 is a right-angle end structure, and when it is rotated to its maximum angle, the right-angle horizontal surface of the right-angle end fits into the concave surface.

[0072] In this embodiment, the middle part of the conveying device 3 is provided with a recess, and the bottom of the supporting base plate is provided with a convex surface that cooperates with the recess.

[0073] The above description is merely a preferred embodiment of the invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
