Description

An environmentally friendly cement product waste recycling device Technical Field

[0001] This utility model relates to the field of cement product waste recycling technology, specifically an environmentally friendly cement product waste recycling device. Background Technology

[0002] Cement waste is mainly generated during the demolition of old houses and infrastructure construction, leading to a lack of suitable disposal methods. Reusing discarded cement blocks not only solves the problem of raw material shortages but also generates considerable profits. Cement waste can be crushed to produce coarse and fine aggregates, which can be used to produce concrete and mortar of corresponding strength grades or to make building materials such as blocks, wall panels, and floor tiles. Alternatively, it can be added to solidification materials for use in the base layer of highway pavements, thereby reducing resource waste. With the widespread application of cement, cement products are produced and used in large quantities, and the resulting cement product waste can be recycled using recycling devices to ensure the full utilization of materials.

[0003] When cement waste crushing and recycling equipment is in operation, the waste generated during crushing will produce a large amount of dust and debris. The debris flying out is not conducive to the recycling operation, and the dust flying in the workshop will not only affect the environmental quality of the workshop, but also harm the health of the workers. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5. This utility model provides a technical solution: an environmentally friendly cement product waste recycling device, including a recycling box 1. The recycling box 1 serves as a temporary storage and primary crushing container for waste. It adopts a double-layer structure, with an inner layer of high manganese steel lining to resist the friction of cement fragments and an outer layer of welded steel frame. The middle layer is filled with sound insulation cotton to reduce noise. The side wall integrates a frequency-adjustable vibrator to prevent waste accumulation. A crushing component 2 is set on the recycling box 1, and an installation frame 3 is installed on the top of the recycling box 1.

[0026] The mounting frame 3 is equipped with a belt conveyor 4, and a second motor base 401 is installed on the belt conveyor 4. The second motor base 401 is located on the outer wall of the mounting frame 3, and a motor is installed on the second motor base 401. The motor is electrically connected to the belt conveyor 4. The belt conveyor 4 is made of wear-resistant steel wire rope core rubber belt with anti-slip texture added to the surface. The second motor base 401 has a built-in reducer and is equipped with an anti-deviation device and an emergency pull rope switch.

[0027] Two side plates 303 are installed on both sides of the top of the mounting frame 3 by screws. A first shielding part 5 is slidably arranged between the two side plates 303. A second shielding part 6 is arranged on the top surface of the mounting frame 3. The first shielding part 5 slides outside the top of the second shielding part 6.

[0028] The second shielding part 6 includes a U-shaped plate 601, with a back plate 602 at one end of the U-shaped plate 601. Both the U-shaped plate 601 and the back plate 602 are located on the top surface of the mounting frame 3. The U-shaped plate 601 and the back plate 602 are made of 304 stainless steel, and silicone sealing strips are embedded at the joints. A transparent observation window is installed on the top of the first shielding part 5 and the second shielding part 6 to facilitate monitoring of the crushing state.

[0029] The first shielding part 5 and the second shielding part 6 have the same structure. Both the first shielding part 5 and the second shielding part 6 have an opening at one end. The first shielding part 5 is slidably sleeved on the second shielding part 6. The first shielding part 5 and the second shielding part 6 protect the recycling box 1 and the crushing component 2 during operation. The first shielding part 5 and the second shielding part 6 form a closed space through a sliding nesting structure to prevent dust from overflowing during the crushing process. The design of the U-shaped plate 601 and the back plate 602 enhances the sealing performance. The side plate 303 is fixed with screws to ensure stability.

[0030] The top surface of the recycling bin 1 is connected to the first connecting hopper 101. An opening is opened on one side of the first connecting hopper 101. The first connecting hopper 101 slides into the dust collection box 103 through the opening. The top of the first connecting hopper 101 is connected to the connecting frame 102. The dust collection box 103 can be slid out for periodic cleaning.

[0031] The connecting frame 102 is equipped with a crushing component 2, which includes a dual-shaft crushing rotor 201 and a first motor base 202. The motor base 202 is equipped with rubber damping pads and spring shock absorbers to reduce the vibration transmitted to the housing. The outer shell of the motor base 202 can be quickly disassembled, with reserved heat dissipation holes and integrated dustproof mesh. The dual-shaft crushing rotor 201 is set inside the connecting frame 102 through bearings and mounting seats. The first motor base 202 is set on the outer side wall of the connecting frame 102. The rotor shaft of the dual-shaft crushing rotor 201 is made of alloy steel with heat treatment and laser-coated tungsten carbide coating on the surface. The blade is a detachable alloy steel module with a serrated cutting edge to enhance the shearing force.

[0032] Two motors are installed on the first motor base 202. The motors are YE3 series high-efficiency and energy-saving models. The speed is adjusted by a frequency converter to adapt to waste materials of different hardness. The output shafts of the two motors are connected to the dual-shaft crushing rotor 201. The output directions of the motors connected to the two rotor shafts of the dual-shaft crushing rotor 201 are opposite, so that the two rotors of the dual-shaft crushing rotor 201 rotate in opposite directions. The blades interlock and mesh with each other. After the cement product waste enters the gap between the blades, it is subjected to multiple forces such as shearing, tearing, and squeezing, and is crushed into small pieces. The blades are densely arranged, and the cement product waste is continuously crushed under the drive of the rotor, thus achieving pulverization.

[0033] The top of the connecting frame 102 is connected to the second connecting bucket 104, which is connected to the mounting frame 3. The bottom surface of the mounting frame 3 has a discharge port 301, which is connected to the second connecting bucket 104. The bottom surface of the mounting frame 3 is equipped with support legs 302. Through the linkage conveying, crushing, and dust collection modules, efficient recycling of waste materials is achieved. The closed design meets environmental protection requirements and is suitable for construction waste treatment scenarios. The discharge port 301 has a funnel-shaped design and is lined with ultra-high molecular weight polyethylene board to reduce material adhesion. The support legs 302 are height-adjustable anchor bolts, and shock-absorbing pads are added to the bottom.

[0034] When recycling cement product waste using the recycling device, cement product waste such as concrete blocks and bricks are evenly placed on the belt conveyor 4. The motor driven by the second motor base 401 drives the conveyor belt to move, conveying the waste into the mounting frame 3. The first shielding part 5 and the second shielding part 6 slide to form a closed space. The waste enters the second connecting hopper 104 through the conveyor, and then falls into the area of ​​the dual-shaft crushing rotor 201 inside the connecting frame 102. It is crushed by the dual-shaft crushing rotor 201. The crushed cement product waste enters the dust collection box 103 through the first connecting hopper 101 for collection. The dust collection box 103 is slidably disassembled to collect the crushed cement product waste, so that the crushed cement product waste can be used for recycled aggregate or roadbed filling and other purposes.
