Description

TECHNICAL FIELD

[0001] The utility model relates to solid waste treatment technical field especially relates to a kind of autoclaved sand aerated concrete block solid waste recycling device. BACKGROUND

[0002] Under the current flourishing of construction industry, autoclaved sand aerated concrete block is widely used in various construction projects due to its excellent properties such as light weight, thermal insulation, fire resistance, etc. However, during the production and manufacturing process of the block, as well as the construction and demolition process of the building project, a large amount of solid waste will be generated. If these wastes are discarded randomly, not only will they occupy a large amount of land resources, but also will cause pollution to the ecological environment.

[0003] However, the traditional recycling method mainly relies on manual crushing, which has a series of drawbacks that cannot be ignored. On the one hand, manual crushing is extremely inefficient and cannot meet the demand of large-scale construction waste treatment, which seriously restricts the progress of recycling work. On the other hand, manual crushing cannot guarantee the uniformity of block crushing, resulting in uneven quality of recycled materials, which makes it difficult to achieve ideal performance requirements in subsequent recycling process, affecting the application range and use effect of recycled materials.

[0004] More seriously, a large amount of dust will be generated during the manual crushing process. These dusts not only cause serious pollution to the working environment, making the air quality of the workplace deteriorate rapidly, threatening the health of the operators and causing respiratory diseases and other occupational health problems; but also spread to the surrounding environment, polluting the atmospheric environment, affecting the quality of life of the surrounding residents and destroying the ecological balance.

[0005] Currently, there are various technical solutions for recycling autoclaved sand aerated concrete block solid waste. For example, patent number CN213000210U "autoclaved sand aerated concrete block solid waste recycling device" uses a crushing roller and a sawtooth to crush the solid waste, and a feeding cylinder to crush the solid waste that has not been completely crushed multiple times, which improves the uniformity of crushing to a certain extent. However, this device cannot accurately control the final crushing particle size, and when facing production processes that require specific particle size materials, it often cannot meet the demand.

[0006] In summary, the existing autoclaved sand aerated concrete block solid waste recycling technology has the problem of being unable to flexibly and accurately adjust the crushing particle size, which makes the recycled materials difficult to be widely used in various production scenarios, limiting the effective recycling of solid waste. UTILITY MODEL CONTENT

[0007] The utility model intends to provide a kind of autoclaved sand aerated concrete block solid waste recycling device, to solve the problem that prior art cannot adjust broken granularity.

[0008] The autoclaved sand aerated concrete block solid waste recycling device of the present application comprises a processing box, which is provided with an inlet and an outlet, and an inclined receiving plate is arranged in the processing box, below the inlet; a drum with a rotating eccentric shaft is rotatably connected in the processing box, above the end of the receiving plate; the drum is connected with a motor; an arcuate jaw plate is rotatably connected in the processing box; a gap is provided between the jaw plate and the drum for the passage of solid waste; and the jaw plate is connected with a driver for deflecting the jaw plate.

[0009] The working principle and advantages of the present application are as follows: autoclaved sand aerated concrete block solid waste (hereinafter referred to as material) is poured into the device through the inlet of the processing box; the material falls on the receiving plate under the action of gravity; when it is necessary to adjust the jaw plate, the driver is turned on to drive the jaw plate to rotate, thereby adjusting the distance between the jaw plate and the drum; when it is necessary to obtain smaller granularity of broken material, the driver controls the jaw plate to rotate towards the drum, so as to reduce the gap between the jaw plate and the drum; conversely, if larger granularity of material is needed, the jaw plate is controlled to move away from the drum to increase the gap; the motor is turned on to drive the eccentric rotation of the drum; the eccentric design of the eccentric shaft causes irregular motion trajectory of the drum during rotation; the distance between each point on the surface of the drum and the jaw plate changes constantly during motion; after the material falling from the receiving plate enters the gap between the jaw plate and the drum, the material is first extruded by the drum and the jaw plate; under the action of strong extrusion force, the internal structure of the material is destroyed and cracks begin to appear; then, due to the irregular motion of the drum, the material is subjected to the friction of the drum surface, and the particles on the surface are gradually ground off; at the same time, the material is continuously impacted by the jaw plate and the inner wall of the processing box under the driving of the drum, further breaking; in this process, the material is continuously extruded, rubbed and impacted until the desired broken granularity is achieved; after being broken by the jaw plate and the drum, the material is discharged from the outlet at the bottom of the processing box due to its own gravity and the centrifugal force generated by the rotation of the drum; the size of the outlet is designed to ensure smooth discharge of the material and prevent larger particles that have not been completely broken from leaking out; the discharged material can directly fall into the collecting container below for subsequent processing and utilization.

[0010] The device realizes efficient recycling through unique design, and the material is poured from the feeding port and slides through the material receiving plate, the gap between the e-plate and the roller can be flexibly adjusted by the driver, and the crushing particle size is accurately controlled; the motor drives the eccentric rotation of the roller to crush the material in multiple ways such as extrusion, friction and impact, which greatly improves the processing efficiency compared with traditional equipment; the inclined material receiving plate and the reasonably designed discharge port not only ensure smooth conveying and discharge quality of the material, but also reduce the risk of blockage and maintenance cost; recycling of the material effectively reduces environmental pollution, saves land resources, reduces dependence on new raw materials, realizes resource recycling, and has economic and ecological benefits.

[0011] Further, the driver includes a wedge block abutting the e-plate, the wedge block is connected with an adjusting oil cylinder, and a resisting block is further arranged in the processing box, and the wedge block is located between the e-plate and the resisting block. The wedge block is driven by the adjusting oil cylinder to move up and down, the wedge block moves up, the widest position of the wedge block abuts the e-plate, and the e-plate is abutted close to the roller, so that the material crushing particle size is reduced.

[0012] Further, the resisting block is connected with a tensioning oil cylinder, and the tensioning oil cylinder is rotationally connected with the e-plate at the telescopic end. The tensioning oil cylinder is used for maintaining the tensioning degree of the e-plate, which can effectively reduce the shaking and displacement caused by partial relaxation, and help to enhance the rigidity of the e-plate. When the wedge block is driven by the adjusting oil cylinder to move up, the tensioning oil cylinder is elongated.

[0013] Further, a plurality of impact plates are detachably connected to the side of the e-plate close to the roller. The tensioning oil cylinder is used for maintaining the tensioning degree of the e-plate, which can effectively reduce the shaking and displacement caused by the relaxation of the e-plate, and further enhance the overall rigidity of the structure where the e-plate is located.

[0014] Further, a plurality of convex points are arranged on the cylindrical surface of the roller. The convex points are arranged, and when the roller rotates, the friction force and impact force between the roller and the material are increased, so that the material is more easily crushed, and the crushing efficiency and effect are effectively improved.

[0015] Further, the material receiving plate includes a plurality of fixed rods, and a screen is arranged on the fixed rods. When smaller particles fall on the material receiving plate, they will be screened out directly through the screen without entering the roller for crushing, which can reduce the invalid work of the roller, improve the overall material processing efficiency, and avoid excessive crushing to cause energy waste and equipment wear and tear.

[0018] The following is further described in detail through specific embodiments:

[0019] The reference signs in the drawings of the specification include: feed hopper 1, processing box 2, feed inlet 201, discharge outlet 202, fixed rod 301, reinforcing rib 302, screen 303, roller 4, rotating eccentric shaft 5, jaw plate 6, impact plate 7, adjusting oil cylinder 8, wedge block 9, abutting block 10, tensioning oil cylinder 11.

[0020] The embodiment is basically as shown in the accompanying drawings Figure 1 and Figure 2 : A device for recycling solid waste of autoclaved sand aerated concrete blocks, comprising a processing box 2, a feed inlet 201 is arranged on the left side of the top of the processing box 2, the feed inlet 201 is connected with a feed hopper 1, a discharge outlet 202 is arranged on the left side of the bottom of the processing box 2, an inclined downward receiving plate is fixedly connected in the processing box 2, the receiving plate comprises a reinforcing rib 302, five fixed rods 301 are fixedly connected on the reinforcing rib 302, a screen 303 is arranged on the five fixed rods 301, the screen 303 is fixedly connected with the reinforcing rib 302, the receiving plate is located below the feed inlet 201, a roller 4 with a rotating eccentric shaft 5 is rotatably connected in the processing box 2, a plurality of convex points are arranged on the cylindrical surface of the roller 4, the lower end of the receiving plate is located above the roller 4, the roller 4 is connected with a motor, an arc-shaped jaw plate 6 is rotatably connected in the processing box 2, a gap for the solid waste to pass through is arranged between the jaw plate 6 and the roller 4, four impact plates 7 are detachably connected on the side of the jaw plate 6 close to the roller 4, the impact plates 7 are detachably connected with the jaw plate 6 through bolts, the jaw plate 6 is connected with a driver for driving the deflection of the jaw plate 6, the driver comprises a wedge block 9 abutting against the jaw plate 6, the wedge block 9 is connected with an adjusting oil cylinder 8, the adjusting oil cylinder 8 is fixedly connected with the top of the processing box 2, an abutting block 10 is fixedly connected in the processing box 2, the wedge block 9 is located between the jaw plate 6 and the abutting block 10, the abutting block 10 is connected with a tensioning oil cylinder 11, the telescopic end of the tensioning oil cylinder 11 is rotatably connected with the jaw plate 6.

[0021] The working process of the device is based on the cooperative operation of each component, which is as follows: the solid waste of autoclaved sand aerated concrete blocks (hereinafter referred to as material) is poured from the feed inlet 201 of the processing box 2, the material falls on the inclined receiving plate under the action of gravity. When it is necessary to adjust the broken particle size of the material, the wedge block 9 is moved up and down by the adjusting oil cylinder 8 in the driver. When the wedge block 9 moves up, its widest position abuts against the jaw plate 6, pushing the jaw plate 6 close to the roller 4, thereby reducing the gap between the jaw plate 6 and the roller 4, so that the broken material with smaller particle size can be obtained; on the contrary, when the wedge block 9 moves down, the jaw plate 6 moves away from the roller 4, thereby increasing the gap to obtain the material with larger particle size.

[0022] After adjusting the distance between the e-plate 6 and the roller 4, the motor is turned on, and the motor drives the roller 4 to rotate eccentrically. Due to the existence of the eccentric shaft, the roller 4 produces an irregular motion track during rotation, so that the distance between each point on the surface of the roller 4 and the e-plate 6 changes constantly. At this time, the material falling from the receiving plate enters the gap between the e-plate 6 and the roller 4. The material is first subjected to extrusion by the roller 4 and the e-plate 6, and the strong extrusion force destroys the internal structure of the material, causing it to crack. Then, the irregular motion of the roller 4 causes the material to be subjected to surface friction, and the particles are gradually ground off. At the same time, the material is also driven by the roller 4 to impact the impact plate 7 and the inner wall of the processing box 2, further crushing.

[0023] During the material crushing process, the tensioning oil cylinder 11 maintains the tension of the e-plate 6, effectively reducing the instability caused by the relaxation of the e-plate 6, such as shaking and displacement, enhancing the overall rigidity of the structure where the e-plate 6 is located, and ensuring stable crushing work. When the adjusting oil cylinder 8 drives the wedge 9 to move upwards, the tensioning oil cylinder 11 is elongated. The four impact plates 7 on the side of the e-plate 6 close to the roller 4 are detachably connected and can be easily replaced after long-term use and damage, ensuring the crushing effect. The multiple protrusions provided on the cylindrical surface of the roller 4 increase the friction and impact force between the roller 4 and the material during rotation, further improving the crushing efficiency.

[0024] In addition, the screen 303 on the surface of the receiving plate plays a key role. When smaller particles fall on the receiving plate, they will be screened out directly through the screen 303 and do not need to enter the roller 4 for crushing, reducing the invalid work of the roller 4, improving the overall material processing efficiency, and avoiding energy waste and equipment wear caused by excessive crushing. The material crushed by the e-plate 6 and the roller 4 is discharged from the discharge port 202 designed at the bottom of the processing box 2 under the action of its own gravity and the centrifugal force generated by the rotation of the roller 4, which can ensure smooth discharge of the material and prevent larger particles that have not been completely crushed from leaking out. The discharged material falls into the lower collecting container, facilitating subsequent processing and utilization.

[0025] Through actual testing, compared with traditional single crushing equipment, the device has achieved a significant improvement in crushing efficiency, with an improvement of about 40%. The reason is that the e-plate 6 and the roller 4 work together to make the material subjected to the combined action of extrusion, friction, and impact during the crushing process. For example, to process 1 ton of autoclaved sand aerated concrete block solid waste, the device only needs about 15 minutes to complete the crushing operation, while the traditional equipment takes about 25 minutes.

[0026] By precisely adjusting the gap between the e-plate 6 and the roller 4, the particle size of the crushed material between 3-40mm can be precisely controlled. Whether used for manufacturing recycled aggregate or as a base material for other building materials, it can meet different particle size requirements. For example, when preparing recycled aggregate for fine concrete, the gap can be adjusted to a minimum value to obtain a very fine material; when producing coarse aggregate for large projects such as dam filling, the gap can be greatly increased to produce a larger particle size material.

[0027] The unique design of the inclined receiving plate greatly reduces the accumulation and blockage of materials inside the device, and the materials can quickly and smoothly enter the crushing area. According to statistics, the number of shutdowns caused by material blockage in the device is reduced by about 70% compared to traditional equipment. The gap between the e-plate 6 and the roller 4, combined with the eccentric rotation of the roller 4, allows the material to be fully stressed during crushing, significantly improving the crushing effect. Compared with similar equipment, the uniformity of the particle size of the material processed by the device is improved by about 35%.

[0028] The entire device has a compact structure and a small footprint, making it easy to install and maintain. According to estimates, the footprint of the device is reduced by about 25% compared to similar equipment, and the routine maintenance period can be extended to 4-8 months, greatly reducing the operating and maintenance costs of the equipment.

[0029] The device can process a large amount of autoclaved sand aerated concrete block solid waste every year, effectively reducing the pollution of waste to the environment. At the same time, recycling these wastes saves a lot of natural resources. Taking a medium-sized construction waste treatment plant as an example, using the device can reduce the accumulation of about 60,000 tons of solid waste per year, equivalent to saving about 25,000 square meters of land resources.

[0030] The above is only an embodiment of the present application, and the specific structure and characteristics of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should be considered as the protection scope of the present application. These will not affect the effect and practicality of the present application. The scope of protection claimed in this application should be based on the content of its claims, and the specific implementation described in the specification can be used to explain the content of the claims.
