Description

Technical Field

[0001] This utility model belongs to the technical field of permeable brick production equipment, specifically relating to a feeding component for producing fine-grained sand-based permeable bricks. Background Technology

[0002] Sand-based permeable bricks are made from sand and extruded using a non-sintering process. They have the functions of permeability and filtration, and are energy-saving and environmentally friendly. By changing the surface tension of water, they achieve permeability and have a dense surface, thus resolving the contradiction between strength and permeability. This results in sand-based permeable materials with high strength, fast permeability, and resistance to dust blockage, providing long-lasting permeability.

[0003] Currently, the raw materials for fine-grained sand-based permeable bricks mainly consist of silica sand, binders, curing agents, and solvents. These raw materials are mixed in a specific ratio, pressed into preforms, and then microwave-cured to obtain the finished product. During the preparation process, the raw materials (generally requiring an average particle diameter of no more than 2 mm) need to be fed to a mixing mixer via a feeding assembly. However, existing feeding assemblies lack screening capabilities, failing to remove large particles (greater than 2 mm) that are not fully crushed and are thus fed into the mixing mixer along with other qualified materials, leading to product quality issues.

[0004] Therefore, improvements are urgently needed. Utility Model Content

[0005] To address the aforementioned deficiencies in existing technologies, this utility model provides a feeding assembly for producing permeable bricks based on fine sand, comprising a mixing machine, a conveyor, a screen, an electric push rod, a pallet, and a crushing mechanism. The mixing machine utilizes existing technology and includes a casing with a feeding port at the top. A mixing device is installed within the casing for mixing materials. The conveyor is inclined, with its discharge end higher than its feed end, and the discharge end is directly above the feeding port of the mixing machine. The screen is located between the discharge end of the conveyor and the feeding port of the mixing machine. A vibrating motor is installed at the bottom of the screen. The electric push rod is positioned on one side of the screen, with its free end extending towards the screen. A push plate is mounted on the free end of the electric push rod. The pallet is inclined on the other side of the screen, with its higher end closer to the screen. The crushing mechanism is positioned below the lower end of the pallet for crushing materials.

[0006] Optionally, the conveyor includes a frame, a drive roller and a driven roller rotatably disposed at both ends of the frame, a conveyor belt connected between the drive roller and the driven roller, and a drive motor for driving the drive roller to rotate. An idler roller group is disposed between the drive roller and the driven roller to support the conveyor belt.

[0007] Optionally, the screen is provided with a fixing frame on the outside. The fixing frame is fixed to the casing of the mixing machine by the bottom support rod, and the fixing frame is fixedly connected to the higher end of the pallet.

[0008] Optionally, a fixed bracket is installed below the electric push rod, and the fixed bracket is fixed to the housing of the mixing mixer.

[0009] Optionally, a brush is provided at the bottom of the push plate, and the bristles of the brush are serrated.

[0010] Specifically, when the electric push rod stretches its free end and drives the push plate to move toward the screen, the brush can be used to push and sweep the large particles of material remaining on the screen onto the tray. The serrated bristles can better cut and peel off the material attached to the screen surface, improving the pushing and sweeping efficiency, and also preventing screen blockage and improving screening efficiency.

[0011] Optionally, the crushing mechanism includes a crushing box, a feed inlet at the top of the crushing box, two opposing and parallel crushing rollers inside the crushing box, a crushing motor for driving the crushing rollers to rotate outside the crushing box, and a ramp at the bottom of the crushing box, with a discharge outlet at the lower end of the ramp.

[0012] Optionally, a storage tank is provided below the discharge port of the crushing box.

[0013] Specifically, the storage tank is used to collect large particles of material that have been screened out.

[0014] Optionally, a material level sensor is installed in the casing of the mixing mixer to detect the material level height in the mixing mixer.

[0015] Specifically, a material level sensor can be used to detect the material level in the mixing mixer. When the material level is too high, the running speed of the conveyor belt can be adjusted by controlling the drive motor, thereby controlling the feed rate.

[0016] This utility model also includes other components that enable the feeding assembly for the production of fine-grained sand-based permeable bricks to function normally, all of which are conventional technical means in the field. Furthermore, any devices or components not specified in this utility model employ conventional technical means in the field, such as vibratory motors, drive motors, electric push rods, and crushing motors.

[0017] The working principle of this utility model is as follows: the raw material is conveyed by a conveyor and falls from the discharge end of the conveyor onto the screen. After falling onto the screen, the vibrating motor is started to vibrate and screen the material on the screen. Material with qualified particle size passes through the mesh and falls into the mixing mixer for mixing, while large particles with unqualified particle size remain on the screen. After processing, a certain amount of unqualified material accumulates on the screen. The electric push rod can be controlled to extend its free end, driving the push plate to move towards the screen. The material on the screen is pushed and swept onto the pallet by a brush. Baffles can be set on both sides of the pallet to reduce material spillage. Then the material rolls down the pallet into the crushing box. The crushing motor is started to crush the material. The crushed material is collected in the storage tank for easy reuse and material saving.

[0018] The beneficial effects of this utility model are that, through the mixing mixer, conveyor, screen and electric push rod, the conveyed materials can be screened to screen out materials with unqualified particle size to ensure product quality; in addition, through the pallet, crushing mechanism and storage tank, unqualified materials can be crushed and recycled, improving material utilization and saving costs.
