Description

Technical Field

[0001] This invention relates to the field of waste crushing and processing equipment, specifically to a crushing and processing equipment for blocky waste materials from road construction. Background Technology

[0002] Construction road block waste crushing and processing equipment is specially designed to efficiently crush blocky materials in road waste such as asphalt and concrete, such as crushed old asphalt blocks and concrete fragments, and simultaneously optimize waste performance and control pollution.

[0003] Currently, in the process of crushing and processing asphalt block waste, when asphalt waste with high water content is crushed, it is easy for the waste to adhere to the crushing rollers after entering the crusher, forming accumulated material. This can lead to equipment blockage, jamming, and other hidden dangers, seriously affecting the stable operation of the crusher, causing the crushed product particle size to fail to meet the standards, and significantly reducing crushing efficiency and continuity. Summary of the Invention

[0004] The purpose of this invention is to provide a crushing and processing device for blocky waste materials on construction roads. High-temperature hot air is sent into the heating frame through an air conveying pipe to form a hot air circulation. Waste materials with high moisture content pass through the hot air zone, and the surface and shallow moisture quickly vaporizes and evaporates, reducing the moisture content and weakening the adhesion. This prevents the material from adhering to the crushing rollers and forming material accumulation after entering the crusher, eliminating the risk of equipment blockage and jamming, ensuring the stable operation of the crusher, making the particle size of the crushed product meet the standards, and greatly improving the crushing efficiency and continuity.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a crushing and processing device for blocky waste materials on construction road surfaces, comprising a crusher, a heat transfer component installed on the crusher, the heat transfer component including a conveyor belt, a heating frame fixedly installed on the conveyor belt, a fan fixedly installed on the heating frame, a circulation pipe fixedly connected to one side of the fan, and the circulation pipe fixedly installed inside the crusher;

[0006] The crusher is equipped with an auxiliary component, which includes a reaction chamber. One side of the reaction chamber is fixedly connected to a circulation pipe. A fan is rotatably installed inside the reaction chamber. A feed wheel is fixedly connected to one side of the fan. One side of the feed wheel is rotatably installed inside a lime box. A water pump is fixedly installed inside the reaction chamber. The output end of the water pump is fixedly connected to a second conveying pipe. A nozzle is fixedly installed on one side of the second conveying pipe.

[0007] Preferably, the discharge port of the crusher is provided with a discharge frame, the interior of which is sloping, and the nozzle is installed through the discharge frame on one side.

[0008] Preferably, an air supply pipe is provided on one side of the heating frame, and a first conveying pipe is fixedly connected to one side of the fan, with one end of the first conveying pipe fixedly connected to one end of the circulation pipe.

[0009] Preferably, one end of the circulation pipe extends through the crusher installation, and a one-way valve is provided at one end of the circulation pipe.

[0010] Preferably, a rotating rod is installed on the fan, a feeding wheel is fixedly installed at one end of the rotating rod, both ends of the rotating rod extend through the fan and the feeding wheel, and both ends of the rotating rod are rotatably mounted on the reaction chamber.

[0011] Preferably, a water supply pipe is connected to one side of the reaction chamber, the fan is located at the lower end of the water supply pipe, and a groove is provided on one side of the reaction chamber, where the fan rotates.

[0012] Preferably, the feeding wheel is provided with multiple sets of grooves, and the lime box is provided with an inclined surface inside.

[0013] Preferably, the lime box is provided with a door, and the door is provided with a handle.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In this invention, high-temperature hot air is sent into the heating frame through the air conveying pipe to form a hot air circulation. Waste materials with high moisture content pass through the hot air zone, and the surface and shallow moisture quickly vaporizes and evaporates, reducing the moisture content and weakening the adhesion. This prevents the material from adhering to the crushing rollers after entering the crusher and forming material accumulation, eliminating the hidden dangers of equipment blockage and jamming, ensuring the stable operation of the crusher, making the particle size of the crushed product meet the standard, and greatly improving the crushing efficiency and continuity.

[0016] 2. In this invention, after the construction personnel start the blower, the waste material in the heating frame is heated, causing the moisture to vaporize and produce water vapor. The original hot air is drawn into the blower inlet along with the water vapor under negative pressure. After initial mixing in the blower, it is stably transported to the first conveying pipe and then flows into the circulation pipe. The circulation pipe is located inside the crusher. Its internal gas circulation can absorb sound and reduce noise, reduce pollution and impact on personnel, and can also release heat to assist in heating the waste material, adjust the viscosity of the old asphalt to promote material mixing, and form high-quality recycled material. The crushed waste material is discharged in an orderly manner through the discharge frame for convenient collection and treatment.

[0017] 3. In this invention, a portion of the water flow impacts the fan, causing it to rotate. The rotating rod drives the feeding wheel to dig out a fixed amount of lime from the lime box, which falls into the reaction tank and reacts with water to form a liquid. The water pump is then started, and the liquid mixture is transported through the second conveying pipe to the porous atomizing nozzle and sprayed onto the broken asphalt waste in the discharge frame. This improves the durability of the waste. At the same time, the liquid mixture adsorbs the dust generated by heating, reducing the dust concentration and preventing it from causing harm to equipment, the environment, and human health.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the implementation of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] See Figures 1 to 3 As shown, the present invention provides a crushing and processing equipment for blocky waste materials on construction road surface, including a crusher 1, a heat transfer component 2 installed on the crusher 1, the heat transfer component 2 including a conveyor belt 201, a heating frame 202 fixedly installed on the conveyor belt 201, a fan 203 fixedly installed on the heating frame 202, a circulation pipe 206 fixedly connected to one side of the fan 203, and the circulation pipe 206 fixedly installed inside the crusher 1;

[0028] During the asphalt pavement recycling process, the construction workers first remove the asphalt block waste material on the construction pavement that has absorbed water and become moist due to summer rainfall. This type of waste material has become significantly sticky due to the water seepage that fills its internal pores with water. It is then collected and cleaned by loaders or manual labor and evenly laid to the starting end of the horizontally running conveyor belt 201. The conveyor belt 201 runs continuously at a stable speed, transporting the asphalt block waste material to the subsequent processing stage.

[0029] When the waste material travels to the conveyor belt 201, it passes through the sealed heating frame 202. At this time, the air duct 204 connected to one side of the heating frame 202 has been connected to the external hot air blower. After the construction personnel start the hot air blower, its internal electric heating element heats up rapidly. The external blower delivers high-temperature hot air through the air duct 204 into the interior of the heating frame 202, forming a uniformly distributed hot air circulation within the frame. When the asphalt block waste with high water content passes through this hot air zone at an appropriate speed, the moisture on the surface and in the shallow interior of the waste material undergoes convection heat transfer with the hot air. Rapid vaporization and evaporation under the action of the process effectively reduces the moisture content of the waste. This process significantly weakens the adhesion of the waste by breaking the bond between moisture and asphalt, thereby preventing the waste from adhering to the surface of the crushing rollers and forming wet mud-like accumulations due to high humidity when it enters the crusher 1. This treatment method eliminates the potential for blockages and jams caused by material adhesion during equipment operation, ensures that the crusher main shaft maintains a stable speed, and ensures that the particle size distribution of the crushed product meets the standard requirements, greatly improving the overall crushing efficiency and the continuity of equipment operation.

[0030] After the construction personnel start the blower 203, in the preheating treatment of the asphalt block waste, the blower 203 starts to operate and immediately generates a continuous and stable suction effect. This effect acts on the internal space of the heating frame 202. At this time, due to the heating operation of the asphalt block waste, the moisture in the waste is rapidly vaporized, thereby generating a large amount of water vapor. At the same time, the hot air originally present in the heating frame 202 is also drawn into the blower inlet along with the water vapor due to the negative pressure environment created by the blower's suction. The water vapor and hot air are initially mixed inside the blower. Then, the blower, with its conveying function, stably transmits these two types of mixed gases to the first conveying pipe 205, thereby realizing the directional and efficient transfer of gas from the heating frame 202 to the first conveying pipe 205.

[0031] After the mixed gas enters the first conveying pipe 205, it continues to flow along the pipe's direction and is eventually transported to the inside of the circulation pipe 206. The water vapor and hot air entering the circulation pipe 206 begin to circulate in an orderly manner within the pipe. Since the circulation pipe 206 is located inside the crusher 1, this circulation design brings two significant effects. On the one hand, the gas flowing inside the circulation pipe 206 can effectively absorb and block the mechanical noise generated during the operation of the crusher 1. Through the buffering and dissipation effect of the gas, the intensity of noise propagation is greatly reduced, thereby effectively preventing noise from polluting the surrounding environment and adversely affecting the hearing and mental health of the operators. On the other hand, the water vapor and hot air circulating in the circulation pipe 206 continuously release heat, which plays an auxiliary heating role for the asphalt block waste material being crushed inside the crusher 1. The suitable temperature environment can reasonably adjust the viscosity of the old asphalt, while promoting the molecular movement and mutual penetration between the old asphalt and newly added asphalt, recycling agents, and other materials, thereby helping these materials to mix better and more fully, ultimately forming a recycled asphalt mixture with uniform performance and stable quality.

[0032] After being crushed by the crusher 1, the asphalt block waste is smoothly discharged through the specially designed discharge frame 101 under the push of the internal mechanical structure of the equipment. The reasonable design of the discharge frame 101 enables the crushed waste to be discharged in a concentrated and orderly manner, which greatly facilitates the construction personnel to carry out efficient collection and subsequent processing operations at the discharge port.

[0033] See Figures 4 to 7 As shown, the crusher 1 is equipped with an auxiliary component 3, which includes a reaction chamber 301. One side of the reaction chamber 301 is fixedly connected to the circulation pipe 206. A fan 303 is rotatably installed inside the reaction chamber 301. A feed wheel 305 is fixedly connected to one side of the fan 303. One side of the feed wheel 305 is rotatably installed inside the lime box 306. A water pump 309 is fixedly installed inside the reaction chamber 301. The output end of the water pump 309 is fixedly connected to a second conveying pipe 310. A nozzle 311 is fixedly installed on one side of the second conveying pipe 310.

[0034] Construction workers first connected one end of the water supply pipe 302 to an external water source. After turning on the water supply, the external water source began to continuously flow into the reaction tank 301 through the water supply pipe 302. During this process, the water supply pipe 302 adopted a diversion design. When the water flowed in the pipe, a portion of the water flowed to the area above the fan 303. The water flow impacted the fan blades of the fan 303, generating a force that drove the fan 303 to begin rotating stably around its central axis. The fan 303 then drove the rotating rod 304 to rotate, and the rotating rod 304 rotated synchronously under the power drive, thus driving the reaction tank 301 to rotate. The feeding wheel 305 connected to the end rotates continuously. The surface of the feeding wheel 305 is designed with grooves. When it rotates into the lime box 306, the grooves will fully contact the lime in the lime box and dig out a certain amount of lime. As the feeding wheel 305 continues to rotate, the lime carried in the grooves is carried out of the lime box 306 and falls accurately into the reaction tank 301. At this time, there is a certain amount of water in the reaction tank 301. The lime entering the tank and the water undergo a full chemical reaction and physical mixing to form a mixture with specific properties. To ensure that the mixture can be delivered to the end of use in a timely manner;

[0035] Construction workers start water pump 309, which draws out the fully mixed liquid from reaction tank 301 through suction port. The extracted mixture enters second conveying pipe 310 under the pressure of water pump 309. The mixture flows along second conveying pipe 310 and is finally delivered to nozzle 311. Nozzle 311 adopts a multi-hole atomization design, which can evenly refine the mixture and spray it into discharge frame 101. At this time, discharge frame 101 contains crushed asphalt block waste. The sprayed mixture will completely cover the surface of the waste. On the one hand, it reacts with the active ingredients in the waste through chemical action to form a dense protective layer, which significantly improves the durability of crushed asphalt block waste, enhances its resistance to rain erosion, ultraviolet aging and chemical corrosion, and extends the service life of the waste in complex environments.

[0036] On the other hand, the circulating pipe 206 continuously heats the asphalt block waste in the discharge frame 101 to reduce the viscosity of the waste and facilitate subsequent processing. However, the heating process causes the fine particles in the waste to be heated and lifted, generating a large amount of dust. If this dust is directly discharged, it will seriously pollute the air environment, cause wear and corrosion to the surrounding equipment, and endanger the respiratory health of the on-site construction personnel. The mixed liquid sprayed by the nozzle 311, while covering the waste, will collide and adsorb with the dust particles in the air, increasing the weight of the dust particles and causing them to settle quickly. This effectively reduces the dust concentration in the air inside the discharge frame 101, thereby building a protective barrier to prevent dust from having an adverse effect on the stability of equipment operation, the quality of the ecological environment, and human health in all aspects.

[0037] When water vapor and hot air form a mixed airflow inside the circulation pipe 206 and continue to circulate, the mixed airflow will be transported to the reaction chamber 301 along a predetermined path. The hot air, as a heat energy carrier, enters the reaction chamber 301 and directly exchanges heat with the water source stored in the chamber. The water source temperature gradually increases through continuous heat conduction. The heated water source can significantly improve the dissolution and reaction conditions of lime particles, not only accelerating the dissociation and diffusion process of lime molecules in water, but also enhancing the activity of the reaction system, thereby comprehensively improving the chemical reaction rate and conversion effect of lime in the reaction chamber 301.

[0038] Meanwhile, the water vapor in the mixed airflow will liquefy upon entering the reaction chamber 301 due to contact with the relatively low-temperature water source surface. The liquefied water droplets will fully mix with the original water source, effectively replenishing the total water volume in the reaction chamber 301. Subsequently, this expanded water source will be directionally transported to the nozzle 311 through the second transmission pipe 310 for subsequent asphalt waste spraying treatment. This achieves both phase change recovery and resource utilization of water vapor, and reduces dependence on external water sources through the circulation supply of liquid water, thus achieving the goal of saving water resources.

[0039] To ensure the stable operation of the entire gas circulation, a one-way valve 207 is specially installed at the connection position of the circulation pipe 206 near the reaction tank 301. This valve only allows gas to flow from the circulation pipe 206 to the reaction tank 301 in one direction. When reverse pressure is generated inside the reaction tank 301 due to pressure changes or liquid level fluctuations, the one-way valve 207 will automatically close to block the liquid backflow channel, thereby effectively preventing the liquid in the reaction tank 301 from flowing back into the circulation pipe 206. This avoids problems such as pipe corrosion, airflow obstruction, or equipment failure caused by liquid intrusion, and ensures the long-term stable operation of the circulation pipe 206.

[0040] In an optional embodiment, the discharge port of the crusher 1 is provided with a discharge frame 101, the interior of the discharge frame 101 is sloping, and the nozzle 311 is installed through the discharge frame 101 on one side.

[0041] It should be noted that the crushed asphalt block waste is discharged through the discharge frame 101 for easy collection by construction personnel. The nozzle 311 not only improves the performance of the crushed asphalt block waste by spraying the mixed liquid, but also works together to control dust pollution.

[0042] In an optional embodiment, an air supply pipe 204 is provided on one side of the heating frame 202, a first conveying pipe 205 is fixedly connected to one side of the fan 203, and a circulation pipe 206 is fixedly connected to one side of the first conveying pipe 205.

[0043] It should be noted that the air supply pipe 204 is used to connect to an external hot air blower to transfer hot air into the heating frame 202, and the first transmission pipe 205 is used to transfer the mixed gas into the circulation pipe 206 for circulation.

[0044] In an optional embodiment, the circulation pipe 206 extends through the crusher 1 on one side, and a one-way valve 207 is provided at one end of the circulation pipe 206.

[0045] It should be noted that, in order to ensure stable gas circulation, a one-way valve 207 is installed at the connection between the circulation pipe 206 and the reaction tank 301. This valve allows gas to flow only from the circulation pipe 206 to the reaction tank 301. When the reaction tank 301 experiences reverse pressure due to pressure or liquid level changes, the one-way valve 207 automatically closes to prevent liquid from flowing back into the circulation pipe 206. This avoids pipe corrosion, airflow obstruction, and equipment failure, ensuring long-term stable operation.

[0046] In an optional embodiment, a rotating rod 304 is mounted on the fan 303. A feeding wheel 305 is fixedly mounted on one end of the rotating rod 304. Both sides of the rotating rod 304 extend through the fan 303 and the feeding wheel 305, and both ends of the rotating rod 304 are rotatably mounted on the reaction chamber 301.

[0047] It should be noted that some of the water flow is directed to the top of the fan 303 according to the preset path, impacting the fan blades and driving it to rotate stably around the axis. The fan 303 transmits power to the rotating rod 304 through mechanical linkage, driving the end feed wheel 305 to rotate continuously.

[0048] In an optional embodiment, a water supply pipe 302 is connected to one side of the reaction chamber 301, a fan 303 is disposed at the lower end of the water supply pipe 302, and a groove is provided on one side of the reaction chamber 301, and the fan 303 rotates inside the groove.

[0049] It should be noted that the water supply pipe 302 is used to connect one end to an external water source, and the groove is used to provide space for the fan 303 to rotate.

[0050] In an optional embodiment, the feeding wheel 305 is provided with multiple sets of grooves, and the lime box 306 is provided with an inclined surface inside.

[0051] It should be noted that the surface of the feeding wheel 305 is provided with a specific groove. When it rotates to the lime box 306, the groove digs out a certain amount of lime. As the feeding wheel 305 rotates, it carries the lime out and accurately falls into the reaction box 301 containing water. The lime and water react and mix fully to form a mixture with specific properties to ensure that it can be delivered to the end of use in a timely manner.

[0052] In an optional embodiment, the lime box 306 is provided with a box door 307, and the box door 307 is provided with a handle 308.

[0053] It should be noted that the box door 307 is used to open and close the lime box 306, making it convenient for construction workers to add lime into the lime box 306, and the handle 308 makes it convenient for construction workers to open and close the box door 307.

[0054] Working principle: In the asphalt pavement recycling construction, the construction workers use loaders or manual labor to clean up the asphalt block waste that absorbs water and becomes more viscous in summer. The waste is then evenly spread on the starting end of the horizontally running conveyor belt 201. The conveyor belt 201 transports the waste. When the waste passes through the sealed heating frame 202, the air supply pipe 204 connected to the heating frame 202 is connected to an external hot air fan. The hot air fan is started, and high-temperature hot air is sent into the heating frame 202 through the air supply pipe 204 to form a hot air circulation. The waste with high moisture content passes through the hot air zone, and the surface and shallow moisture quickly vaporizes and evaporates, reducing the moisture content and greatly improving the crushing efficiency and continuity.

[0055] After the construction personnel start the blower 203, the blower generates a continuous suction force to act on the heating frame 202 during the preheating treatment of asphalt block waste. The waste in the frame is heated, causing the moisture to vaporize and produce water vapor. The original hot air is drawn into the blower inlet along with the water vapor under negative pressure. After preliminary mixing in the blower, it is stably transported to the first conveying pipe 205 and then flows into the circulation pipe 206. The circulation pipe 206 is located inside the crusher 1. The gas circulation inside it can absorb and block mechanical noise, reduce pollution and its impact on personnel, and at the same time release heat to assist in heating the waste in the crushing operation, adjust the viscosity of the old asphalt, promote material mixing, and form a high-quality recycled asphalt mixture. The crushed waste is discharged in a centralized and orderly manner through the discharge frame 101, which is convenient for construction personnel to collect and process.

[0056] Construction workers connect the water supply pipe 302 to an external water source. After turning on the water source, the water flows into the reaction tank 301 through the water supply pipe 302. The pipe is divided, and part of the water flow impacts the fan 303 to make it rotate. The rotating rod 304 drives the feeding wheel 305 to dig out a certain amount of lime from the lime box 306 and drop it into the reaction tank 301 to react and mix with water to form a liquid. The water pump 309 is started, and the mixture is transported through the second conveying pipe 310 to the porous atomizing nozzle 311 and sprayed onto the broken asphalt waste in the discharge frame 101 to improve the durability of the waste. At the same time, the mixture adsorbs the dust generated by heating, reduces the dust concentration, and prevents it from causing harm to equipment, the environment, and human beings.

[0057] Water vapor and hot air form a mixed airflow in the circulation pipe 206 and circulate. It is then transported along the path to the reaction chamber 301. The hot air exchanges heat with the water source in the chamber, which heats the water source and accelerates the lime dissolution reaction, thereby improving the reaction rate and effect. Water vapor liquefies upon contact with the water source and, after fusion, is transported to the nozzle 311 for spraying via the second transmission pipe 310, thus realizing the recovery and utilization of water vapor and saving water resources.
