Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly building materials production, and in particular to a molding device for composite brick making from coal gangue and sludge. Background Technology

[0002] Coal gangue, a solid waste generated during coal mining and washing, often faces the problem of large-scale accumulation and difficulty in effective disposal. Combining coal gangue with sludge to make bricks achieves the resource utilization of solid waste. However, the physical properties of coal gangue and sludge differ significantly, and the mixed raw materials are prone to stratification and segregation during the molding process, leading to unstable brick quality. Furthermore, existing molding equipment often lacks effective compaction and venting measures, resulting in internal pores and cracks in the bricks, reducing their strength and durability.

[0003] Traditional brick-making processes using coal gangue and sludge composite materials mostly produce solid bricks, which lack breathability and drainage, making them unsuitable for certain building scenarios. For example, the application of solid bricks is limited in building projects requiring good ventilation or drainage. Utility Model Content

[0004] The purpose of this invention is to provide a molding device for composite brick making from coal gangue and sludge, which solves the problems of unstable brick molding quality and limited applicability of solid bricks in the existing composite brick making process from coal gangue and sludge.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A molding device for composite bricks made from coal gangue and sludge includes a support frame, a mold cavity fixedly connected to the top of the support frame, bricks being formed in the mold cavity, a partition plate fixedly connected inside the support frame, a push plate slidably connected inside the mold cavity, the push plate being used to push the formed bricks out of the mold cavity, a connecting seat fixedly connected to the bottom of the push plate, an electric push rod installed at the bottom of the partition plate, and the output end of the electric push rod being fixedly connected to the connecting seat.

[0006] Preferably, a support platform is fixedly connected to one side of the mold cavity, and a receiving chamber is fixedly connected to the top of the support platform. The receiving chamber is used to hold the composite raw material of coal gangue and sludge. A movable cavity is slidably connected to the bottom of the receiving chamber. The upper and lower sides of the movable cavity are open. Under normal conditions, the movable cavity is aligned with the receiving chamber, and the upper opening of the movable cavity is the same size as the receiving chamber. The lower opening of the movable cavity is closed by the support platform. A baffle is fixedly connected to one side of the movable cavity, and the baffle is flush with the upper opening of the movable cavity.

[0007] Preferably, a horizontal plate is symmetrically fixedly connected inside the support below the mold cavity, and a column is fixedly connected at equal intervals on the top of the horizontal plate. The column is set inside the mold cavity and is slidably connected inside the push plate. The column makes the formed brick have holes. This type of brick with holes has better air permeability and drainage performance in certain specific building scenarios.

[0008] Preferably, a support rod is fixedly connected to the top of the bracket on one side of the mold cavity. A movable arm is rotatably connected to the outer side of the top of the support rod. A slide rod is slidably connected to the end of the movable arm away from the support rod. An extrusion mold is fixedly connected to the bottom of the slide rod. The bottom of the extrusion mold has a hole corresponding to the shape and position of the column. The size of the extrusion mold is adapted to the inside of the mold cavity. By rotating the movable arm and raising and lowering the slide rod, the extrusion mold can accurately reach the top of the mold cavity and descend to compact the raw material, thereby improving the density and strength of the brick.

[0009] Preferably, a pressing arm is rotatably connected to the top of the slide bar, and a connecting rod is symmetrically rotatably connected to the outer side of the movable arm away from the support rod. One end of the connecting rod is rotatably connected to the pressing arm. The structure of the pressing arm and the connecting rod provides a labor-saving operation method for raising and lowering the slide bar, reducing the labor intensity of the operator.

[0010] Preferably, casters are installed at all four corners of the bottom of the support frame. The installation of casters gives the molding device good mobility and makes it easy to move between different work sites.

[0011] Preferably, a reinforcing plate is fixedly connected between the mold cavity sidewall and the support platform. The reinforcing plate enhances the connection strength between the mold cavity and the support platform, thereby improving the structural stability of the entire device.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. This utility model achieves a simple transfer of raw materials from the receiving chamber to the mold cavity by cooperating with the movable cavity and the receiving chamber. The movable cavity is open at the top and bottom and is aligned with the receiving chamber in the normal state. The raw materials fall naturally into the movable cavity. When it is necessary to add material, the movable cavity is pulled to slide into the mold cavity, and the raw materials slowly fall into the mold cavity. At the same time, the baffle gradually covers the bottom opening of the receiving chamber to prevent the raw materials from spilling or being added in excess. This not only ensures the accuracy of the amount of raw materials added each time, but also avoids the difference in brick quality caused by uneven addition of raw materials.

[0014] 2. This utility model uses a column structure to create porous bricks, improving their air permeability and drainage. By rotating the movable arm and raising and lowering the slide bar, the extrusion mold can be accurately moved above the mold cavity and lowered to compact the raw material. The compacted bricks have higher strength and stability, can withstand greater pressure and load, reduce the probability of brick breakage and cracking during use, and improve the quality and service life of the bricks.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 This embodiment provides a molding device for composite bricks made from coal gangue and sludge, including a support 1, a mold cavity 2 fixedly connected to the top of the support 1, bricks being formed in the mold cavity 2, a partition 3 fixedly connected inside the support 1, a push plate 4 slidably connected inside the mold cavity 2, the push plate 4 being used to push the formed bricks out of the mold cavity 2, a connecting seat 5 fixedly connected to the bottom of the push plate 4, an electric push rod 6 installed at the bottom of the partition 3, and the output end of the electric push rod 6 being fixedly connected to the connecting seat 5;

[0022] The composite raw material of coal gangue and sludge is formed in the mold cavity 2. The electric push rod 6 is activated. The output end of the electric push rod 6 pushes the connecting seat 5, which in turn drives the push plate 4 to slide upward in the mold cavity 2, pushing the formed brick out of the mold cavity 2.

[0023] A support platform 7 is fixedly connected to one side of the mold cavity 2. A receiving chamber 8 is fixedly connected to the top of the support platform 7. The receiving chamber 8 is used to hold the composite raw material of coal gangue and sludge. A movable chamber 9 is slidably connected to the bottom of the receiving chamber 8. The upper and lower sides of the movable chamber 9 are open. Under normal conditions, the movable chamber 9 is aligned with the receiving chamber 8, and the upper opening of the movable chamber 9 is the same size as that of the receiving chamber 8. The lower opening of the movable chamber 9 is closed by the support platform 7. A baffle 10 is fixedly connected to one side of the movable chamber 9. The baffle 10 is flush with the upper opening of the movable chamber 9.

[0024] Initially, the receiving chamber 8 is filled with composite raw materials of coal gangue and sludge, and the raw materials fall into the movable chamber 9. When it is necessary to add material to the mold cavity 2, the movable chamber 9 is pulled, causing it to slide along the bottom of the receiving chamber 8 towards the mold cavity 2. As the movable chamber 9 slides, it gradually moves from being aligned with the receiving chamber 8 to being above the mold cavity 2. The raw materials in the movable chamber 9 slowly fall into the mold cavity 2 due to gravity. At the same time, the baffle 10 fixedly connected to one side of the movable chamber 9 will also move with the movable chamber 9, slowly covering the bottom opening of the receiving chamber 8 to prevent the remaining raw materials in the receiving chamber 8 from continuing to fall into the movable chamber 9 or spilling out.

[0025] Inside the support 1, a horizontal plate 11 is symmetrically fixedly connected below the mold cavity 2. Columns 12 are fixedly connected at equal intervals on the top of the horizontal plate 11. The columns 12 are located inside the mold cavity 2 and are slidably connected inside the push plate 4, so that the formed bricks have holes. These perforated bricks have better air permeability and drainage properties in certain specific building scenarios, thus broadening the application range of bricks.

[0026] A support rod 13 is fixedly connected to the top of the bracket 1 on one side of the mold cavity 2. A movable arm 14 is rotatably connected to the outer side of the top of the support rod 13. A slide rod 15 is slidably connected to the end of the movable arm 14 away from the support rod 13. An extrusion mold 16 is fixedly connected to the bottom of the slide rod 15. The bottom of the extrusion mold 16 has a hole corresponding to the shape and position of the column 12. The size of the extrusion mold 16 is adapted to the interior of the mold cavity 2.

[0027] After the raw material is added into the mold cavity 2, the movable arm 14, which is rotatably connected to the outer side of the top of the support rod 13, is rotated so that the end of the movable arm 14 away from the support rod 13 rotates to the top of the mold cavity 2. At this time, the extrusion mold 16, which is slidably connected to the bottom of the slide rod 15 at the inside of the movable arm 14, also rotates to the top of the mold cavity 2. By pressing down the slide rod 15, the extrusion mold 16 descends into the mold cavity 2. Since the bottom of the extrusion mold 16 has a hole corresponding to the shape and position of the column 12, the extrusion mold 16 can descend smoothly and compact the raw material in the mold cavity 2 to form a dense brick. After compaction, the slide rod 15 is lifted so that the extrusion mold 16 leaves the mold cavity 2.

[0028] A pressing arm 17 is rotatably connected to the top of the slide rod 15. A connecting rod 18 is symmetrically rotatably connected to the outer side of the movable arm 14 away from the support rod 13. One end of the connecting rod 18 is rotatably connected to the pressing arm 17. When it is necessary to press down the slide rod 15 to lower the extrusion mold 16, the operator pushes the pressing arm 17 upward. The pressing arm 17 drives the connecting rod 18 to rotate. The rotation of the pressing arm 17 generates a downward component force, which in turn pushes the slide rod 15 down, thereby pressing down the extrusion mold 16. This pressing method is similar to the operation of a hand pump. Through the lever principle, the operator can control the raising and lowering of the slide rod 15 with less effort.

[0029] The bracket 1 is equipped with casters 19 at all four corners of its bottom. When the molding device needs to be moved, the operator only needs to apply a certain external force to push the device, and the casters 19 will roll on the ground, thereby moving the entire molding device to the designated position.

[0030] A reinforcing plate 20 is fixedly connected between the side wall of the mold cavity 2 and the support platform 7. The presence of the reinforcing plate 20 can withstand and disperse the force, making the connection between the mold cavity 2 and the support platform 7 more stable.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
