Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a sludge fermentation extrusion molding machine for red brick processing. Background Technology

[0002] Silt is a sediment formed at the bottom of water bodies such as urban sewers, rivers, lakes, reservoirs, and bays through long-term physical, chemical, and biological processes and water transport. Current silt removal methods typically involve pumping the silt into silt trucks, transporting it to a silt treatment plant, and allowing it to dry naturally through stockpiling to obtain silt blocks, which are then used for landfilling, fertilizer, and building materials.

[0003] For example, CN215660870U discloses a sludge fermentation extrusion molding machine for red brick processing, which includes a frame, a homogenizing chamber, a transfer chamber, a brick pressing hopper and a brick pressing device. The homogenizing chamber is located at the top of the frame, and a sludge feeding hopper is located at the top left end of the homogenizing chamber. The transfer chamber is located at the bottom of the homogenizing chamber, and a brick pressing hopper is located below the transfer chamber. A condensation chamber is located at the bottom outer end of the brick pressing hopper. A brick pressing device is located on the bottom left side of the frame, and a brick pressing device is located on the bottom right side of the frame.

[0004] However, in existing technologies, the sludge is not sufficiently crushed and screened during pretreatment, or it may clump together, resulting in particles of varying sizes. This uneven particle size leads to uneven material flow during extrusion, affecting the dimensional accuracy and appearance quality of the molded product. Larger particles may get stuck in the mold, causing blockages, or form protrusions on the product surface, while smaller particles may fill the gaps between larger particles, resulting in uneven product density. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that uneven particle size causes uneven material flow during extrusion, affecting the dimensional accuracy and appearance quality of the molded product. Therefore, this invention proposes a mud fermentation extrusion molding machine for red brick processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sludge fermentation extrusion molding machine for red brick processing, comprising a crushing box and a moving platform, a driving mechanism is installed on the inner side of one end of the crushing box, and two crushing rollers are symmetrically rotatably connected to the inner side of the other end of the crushing box, a screen is fixedly connected to the inner side of the crushing box, a guide plate is fixedly connected to the bottom of the inner cavity of the crushing box, a discharge port is fixedly connected to one end of the guide plate, and a molding mechanism is installed on the top of the moving platform;

[0007] The molding mechanism includes a molding die and a lifting frame. The molding frame is fixedly connected to the side wall of the molding die, and a sliding rod is fixedly connected to the top of the inner cavity of the molding frame. Both ends of the lifting frame are slidably connected to the sliding rod, and a baffle is fixedly connected to the bottom of the sliding rod.

[0008] Preferably, a spring is provided on the inner side of the lifting frame, the spring is sleeved on the outer surface of the slide rod, and a pusher block is fixedly connected to the center of the inner cavity of the lifting frame.

[0009] Preferably, a drive motor is fixedly installed on one side of the crushing box, and the output end of the drive motor is fixedly connected to one of the crushing rollers.

[0010] Preferably, gears are fixedly connected to the outer surface of one end of each of the two crushing rollers, and the two gears are meshed together.

[0011] Preferably, the drive mechanism includes a fixed plate, which is fixedly connected to the crushing box, and a cylinder is installed at the bottom of the fixed plate.

[0012] Preferably, an extrusion plate is fixedly connected to the cylinder output end, and the extrusion plate is matched with the forming mold.

[0013] Preferably, limit rods are fixedly connected to both sides of the top of the extrusion plate, with the top of the limit rods penetrating through the fixed plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the driving motor drives the crushing roller to rotate synchronously in opposite directions to ensure that the sludge is fully crushed, so that the particles are uniform and large pieces of material are avoided from affecting subsequent processing. The screen further screens the sludge to remove impurities, improve purity, and optimize the quality of subsequent extrusion molding. At the same time, the guide plate guides the screened sludge to flow smoothly to the discharge port to prevent material accumulation and improve conveying efficiency. Finally, the molding die and the extrusion plate work together to ensure that the sludge is shaped and extruded to form a product with stable structure and uniform shape, thereby improving the quality of finished products and production stability.

[0016] 2. In this utility model, the extrusion plate is driven downward by a cylinder to ensure that the forming mold and the extrusion plate are closely matched, ensuring that the raw material is evenly compressed, improving the density and shape accuracy of the finished product. At the same time, the pusher block moves downward synchronously, applying pressure to the material in the mold cavity to fully fill it and ensure the quality of the red brick. After molding is completed, the cylinder stops applying pressure, the spring releases the stored elastic energy, and pushes the lifting frame and the pusher block upward, so that the red brick can be easily demolded and the material can be automatically discharged. This process optimizes the production process, ensures that the finished product is quickly and safely removed, improves the overall production efficiency, and is suitable for large-scale red brick manufacturing.

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a sludge fermentation extrusion molding machine for red brick processing, including a crushing box 1 and a moving platform 3. A drive mechanism 4 is installed on the inner side of one end of the crushing box 1, and two crushing rollers 16 are symmetrically rotatably connected to the inner side of the other end of the crushing box 1. A screen 12 is fixedly connected to the inner side of the crushing box 1. A guide plate 13 is fixedly connected to the bottom of the inner cavity of the crushing box 1. A discharge port 14 is fixedly connected to one end of the guide plate 13. A molding mechanism 2 is installed on the top of the moving platform 3.

[0025] The molding mechanism 2 includes a molding mold 22 and a lifting frame 23. A molding frame 21 is fixedly connected to the side wall of the molding mold 22. A sliding rod 26 is fixedly connected to the top of the inner cavity of the molding frame 21. Both ends of the lifting frame 23 are slidably connected to the sliding rod 26. A baffle 25 is fixedly connected to the bottom end of the sliding rod 26.

[0026] A spring 27 is provided inside the lifting frame 23, and the spring 27 is sleeved on the outer surface of the slide rod 26. A pusher block 24 is fixedly connected to the center of the inner cavity of the lifting frame 23. A drive motor 11 is fixedly installed on one side of the crushing box 1, and the output end of the drive motor 11 is fixedly connected to one of the crushing rollers 16.

[0027] The specific settings and functions of this embodiment are described below. During the crushing process, after the sludge is poured into the crushing chamber 1, it is driven by the drive motor 11, which rotates one of the crushing rollers 16. Simultaneously, power is transmitted through two meshing gears 15, causing the two crushing rollers 16 to rotate synchronously in opposite directions. This thoroughly crushes the sludge entering the crushing chamber 1, ensuring uniform sludge particles and preventing large pieces from affecting subsequent processing. During this process, the screen 12 further filters the crushed sludge, effectively removing impurities and improving its purity, thereby optimizing the quality of subsequent extrusion molding.

[0028] Furthermore, to ensure the smooth transport of the screened sludge to the molding stage, the guide plate 13 is designed to guide the screened sludge towards the discharge port 14, preventing material accumulation and improving transport efficiency. The sludge discharged through the discharge port 14 is transported into the molding die 22, where the moving platform 3 controls its precise movement to position it in the appropriate extrusion processing location. During the extrusion stage, the extrusion plate 42, in conjunction with the molding die 22, shapes and extrudes the sludge, ensuring uniform product shape and stable structure, thereby improving the quality and production efficiency of the final molded product.

[0029] Example 2: Figure 2 - Figure 4 As shown, gears 15 are fixedly connected to the outer surface of one end of each of the two crushing rollers 16, and the two gears 15 are meshed together. The drive mechanism 4 includes a fixed plate 44, which is fixedly connected to the crushing box 1, and a cylinder 41 is installed at the bottom of the fixed plate 44. An extrusion plate 42 is fixedly connected to the output end of the cylinder 41, and the extrusion plate 42 matches the forming mold 22. Limiting rods 43 are fixedly connected to both sides of the top of the extrusion plate 42, and the top of the limiting rods 43 penetrates through the fixed plate 44.

[0030] The overall effect of this embodiment is that, during the extrusion process, the cylinder 41 drives the extrusion plate 42 to move downwards, so that the forming mold 22 cooperates with the extrusion plate 42 to achieve uniform extrusion of the raw material, thereby ensuring the forming quality of the red brick. During this process, the pusher block 24 also moves downwards synchronously with the extrusion plate 42, applying pressure to the material in the forming mold 22 to fully fill the mold cavity, thereby ensuring the density and shape accuracy of the finished product.

[0031] Meanwhile, driven by the cylinder 41, the lifting frame 23 slides relative to the slide bar 26, applying pressure to the spring 27, causing the spring 27 to compress and accumulate elastic energy. Once extrusion molding is complete, the cylinder 41 stops applying pressure, and the spring 27 releases its stored elastic energy, pushing the lifting frame 23 upwards. This causes the pusher block 24 to push the formed brick out of the mold, allowing it to be easily demolded, thus achieving automatic material discharge. This process not only improves production efficiency but also reduces manual intervention, ensuring that the finished product can be quickly and safely removed, facilitating subsequent handling and stacking.

[0032] The operating method and working principle of this device are as follows: First, the sludge is poured into the crushing box 1. The drive motor 11 is started, which drives one of the crushing rollers 16 to rotate. Through the transmission of two meshing gears 15, the two crushing rollers 16 rotate synchronously and in opposite directions, thereby crushing the sludge and preventing the formation of large pieces. Next, the sludge is further screened using a screen 12 to remove impurities, thus improving the efficiency and effect of subsequent extrusion processing. Due to the guiding effect of the guide plate 13, the screened sludge flows to the discharge port 14 and is then conveyed into the forming mold 22. The moving platform 3 controls the movement of the forming mold 22 so that the extrusion plate 42 cooperates with the forming mold 22 to complete the extrusion molding operation.

[0033] During the extrusion process, cylinder 41 drives extrusion plate 42 to move downwards, so that molding die 22 and extrusion plate 42 work together to complete the extrusion molding. At the same time, extrusion plate 42 pushes pusher block 24 downwards. During this process, lifting frame 23 slides along slide rod 26 and compresses spring 27. After extrusion molding is completed, spring 27 uses its own elasticity to push lifting frame 23 upwards, and then discharges the material through pusher block 24, making it easy to remove the molded bricks.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
