Description

Technical Field

[0001] The invention belongs to the field of construction waste treatment, and in particular relates to a solid waste treatment device for building construction projects. Background Art

[0002] During the construction of houses, a large amount of solid waste will be generated, mainly including waste concrete and brick and tile fragments. If these solid construction wastes are not properly handled, they will have a great impact on the environment.

[0003] The treatment method for this part of solid construction waste is to crush it and use it as recycled aggregate to produce new concrete products, such as recycled concrete blocks, recycled concrete pavement bricks, etc.

[0004] At present, after the muck truck loads the solid construction waste from the construction site, it needs to be transported to a designated area for storage, and then transported little by little by transportation equipment to a designated treatment plant for treatment. The treated crushed stone is then transported to a factory specializing in the production of recycled concrete or bricks for processing. During the loading and unloading process, frequent loading and unloading of these solid construction wastes will generate a lot of dust, and it is difficult to take effective dust prevention measures for the dust generated during the loading and unloading process. At the same time, when the solid waste crushing and processing equipment is used for processing, in order to ensure the dust reduction effect, a large amount of water needs to be sprayed continuously. This method will not only cause water stains on the surface of the subsequent crushed materials, which is not convenient for subsequent transportation, but also generate a large amount of muddy water that cannot be effectively treated.

[0015] Compared with the prior art, the solid waste treatment equipment for building construction provided by the embodiment of the present invention has the following beneficial effects:

[0016] 1. In the present invention, the fixing seat in the shock absorbing mechanism is filled with water, and a plurality of shock absorbing springs are arranged between the pressure plate and the inner wall of the fixing seat. The impact force generated on the receiving platform will act on the pressure plate. The shock absorbing spring and the water filled inside the fixing seat cooperate to effectively weaken the transmission of vibration and have a certain shock absorbing effect.

[0017] 2. In the present invention, solid construction waste generates downward pressure by falling on the receiving platform. The downward pressure force generated by the cycle will cause the pressure plate to continuously perform piston action in the fixed seat with the cooperation of the shock-absorbing spring, thereby circulating the external water source into the fixed seat. At the same time, the water inside the fixed seat can be circulated and pressed into the spray mechanism for spraying to perform dust reduction operations. Relying on the gravity of the continuously falling solid construction waste and the cooperation of the shock-absorbing spring, an automatic spraying effect is achieved, which is more energy-saving and environmentally friendly.

[0018] 3. In the present invention, solid construction waste falls from the top of the discharge box and falls on the diversion rollers staggered between the two side plates, so that the solid construction waste originally concentrated in one place is dispersed, and the solid waste falling on the surface of the receiving platform is more dispersed, which not only disperses the impact force of the solid waste on the receiving platform and reduces the bearing pressure of the receiving platform, but also makes it easier for the waste falling on the surface of the receiving platform to slide down from the upper slope of the receiving platform more smoothly.

[0019] 4. In the present invention, the equipment is connected to the concrete recycling mixing tank in the concrete recycling plant, and water of a certain depth is introduced into the water tank. The left end of the conveying mechanism is below the water level inside the water tank. After the solid waste is crushed, the crushed materials will directly fall into the water inside the water tank and finally fall on the conveyor belt. The crushed materials are fully in contact with the water, which greatly reduces the dust dispersion after crushing. The crushed solid construction waste is finally sent to the recycling mixing tank through the conveyor belt. At the same time, a large amount of water containing mud and sand is stored in the water tank. The water containing mud and sand can be extracted according to a certain proportion through an external suction device and introduced into the concrete recycling mixing tank, and used as concrete recycling batching water, thereby effectively solving the mud and water treatment problem generated after spraying.

[0020] 5. In the present invention, the driving mechanism can cooperate with the motor to control the salvage frame to cyclically salvage floating objects on the water surface inside the water tank. Compared with manual regular salvage, it reduces the difficulty of maintenance and reduces manpower investment. BRIEF DESCRIPTION OF THE DRAWINGS

This equipment is connected to an external concrete regeneration mixing tank, a certain amount of water is introduced into the water tank 1, and solid construction waste falls from a certain height onto multiple diversion rollers 502, and the solid construction waste concentrated in one place is separated and evenly falls on the slope of the upper end face of the receiving platform 5, and finally slides onto the crushing mechanism 7 through the guide plate 8 for crushing, and the crushed debris falls onto the conveyor belt 202 in the water inside the water tank 1, and then is transported by the conveyor belt 202 to the external concrete regeneration mixing tank for regeneration treatment.

[0032] See also Figure 2 , Figure 3 as well as Figure 5 The shock absorbing mechanism 6 includes a fixing seat 601 with an opening upward, and the fixing seat 601 is fixed between the front and rear inner walls of the water tank 1. A pressing plate 602 is movably arranged on the upper part of the fixing seat 601, and the upper part of the pressing plate 602 is fixedly connected to the bottom of the receiving platform 5 through a plurality of pillars 603. A plurality of shock absorbing springs 604 are fixedly arranged between the bottom of the pressing plate 602 and the inner wall of the fixing seat 601. Through holes are arranged on both sides of the fixing seat 601. The through hole on the left side of the fixing seat 601 is connected to the two spraying mechanisms 4 through the connecting pipe 1 11, and the through hole on the right side of the fixing seat 601 is connected to the external water supply equipment through the connecting pipe 2 12, and a one-way conducting valve is arranged on both the connecting pipe 1 11 and the connecting pipe 2 12.

[0033] In order to reduce the vibration when solid construction waste is poured into the receiving platform 5 for crushing, the receiving platform 5 and the pressure plate 602 are fixedly connected together by the pillar 603. When the receiving platform 5 is subjected to downward impact force, the bottom of the pressure plate 602 provides pressure to the water inside the fixed seat 601, and at the same time weakens the vibration transmitted by the receiving platform 5, and cooperates with the shock-absorbing spring 604 to achieve a shock-absorbing effect. When the pressure plate 602 moves downward, the water in the fixed seat 601 is pressed into the connecting pipe 11, and is sprayed from the spray mechanism 4 at the corresponding position to spray and remove the dust generated by the impact inside the discharge box 3. At the same time, when the pressure of the pressure plate 602 is reduced or disappears, the shock-absorbing spring 604 drives the pressure plate 602 to move upward, so that negative pressure is generated under the pressure plate 602, thereby pumping external water into the fixed seat 601 through the connecting pipe 2 12, thereby achieving an energy-saving effect.

[0034] See 2 and Figure 5 , one spray mechanism 4 is fixed on the left inner wall of the material box 3, and the other spray mechanism 4 is fixed on the right outer wall of the material box 3.

The nozzles 402 on the spray mechanism 4 on the left side of the material box 3 face upward, and the nozzles 402 on the spray mechanism 4 on the right side of the material box 3 face downward. The downward pressure of the pressing plate 602 allows the water inside the fixing seat 601 to enter the nozzle 402 through the connecting pipe 11 and be sprayed out. The sprayed water has a dust removal effect on the one hand, and on the other hand, most of the water will eventually fall into the water tank 1 to replenish the water in the water tank 1.

[0040] During specific operation, the device is connected to an external concrete recycling mixing tank to directly transport the solid construction waste generated in the construction area to the concrete recycling plant, reducing the steps of frequent transportation of intermediate solid construction waste, thereby reducing the escape of dust.

These solid construction wastes are evenly scattered on the receiving platform 5 after being diverted by the diverter roller 502, and finally slide into the crushing mechanism 7 for crushing. At the same time, the pressure on the receiving platform 5 acts on the pressure plate 602 through the support 603, and the shock-absorbing spring 604 and The fixed seat 601 cooperates to reduce vibration and drive external water to be sprayed to the designated position through the spray mechanism 4 for dust removal. The solid construction waste is deeply crushed in the crushing mechanism 7, and the crushed debris falls onto the conveyor belt 202 in the water inside the water tank 1, and then is transported to the external concrete recycling mixing tank by the conveyor belt 202. The water in the water tank 1 is mainly supplemented by the water sprayed by the spray mechanism 4. At the same time, the muddy water in the water tank 1 can be used as batching water for recycled concrete production, which solves the problem that the muddy water generated in the process of crushing solid construction waste is inconvenient to handle.
