Description

Technical Field

[0001] This invention relates to the field of solid waste resource utilization technology, specifically to a system for preparing dry-mixed mortar from all solid waste and its preparation process. Background Technology

[0002] Solid waste refers to all solid waste. With the acceleration of urbanization and the rapid development of industry, the amount of solid waste generated has increased exponentially, including construction waste, tailings, fly ash, slag and other industrial waste. The accumulation of these solid wastes not only occupies a large amount of land resources, but also causes serious pollution to the surrounding ecological environment, such as soil pollution, water pollution and air pollution such as dust, which bring many negative impacts to ecological balance and human health.

[0003] In the current technology, the demand for dry-mixed mortar in the construction industry continues to grow steadily. The production of traditional dry-mixed mortar mainly relies on raw materials such as natural sand and cement. However, natural sand resources are non-renewable resources, and over-exploitation has led to resource shortages. Converting solid waste into dry-mixed mortar can reduce dependence on traditional resources such as natural sand. However, the current dry-mixed mortar preparation requires the use of multiple devices to complete screening, crushing and mixing, which consumes too much electricity. The prepared dry-mixed mortar also has insufficient durability during long-term use.

[0004] Therefore, we propose a system for preparing dry-mixed mortar from all solid waste and its preparation process to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a system for preparing dry-mixed mortar from solid waste and its preparation process, so as to solve the problems of high energy consumption and insufficient durability of the current dry-mixed mortar preparation devices and processes mentioned in the background art.

An air supply pipe is fixedly connected to one end of the fixing pipe. A heating coil is provided on the inner wall of one end of the air supply pipe. A protective mesh plate is fixedly connected to one end of the air supply pipe.

[0007] Preferably, the outer surface of the fixed cover is provided with a rotating groove, and the inner wall of the fixed cover is fixedly connected with a fixed bearing, and the inner wall of the fixed bearing is fixedly connected to the outer surface of the air duct.

[0008] Preferably, a first connecting cylinder is fixedly connected to one side of one of the first fixing rings, a second connecting cylinder is fixedly connected to one side of one of the second fixing rings, a limit ring is fixedly connected to the outer surface of one of the first fixing rings, and a drive wheel is fixedly connected to the output shaft of the servo motor, with the outer side of the drive wheel in contact with the outer side of the limit ring.

[0009] Preferably, the support assembly includes a first support column and a second support column. A controller is disposed on the outer surface of the second support column. The servo motor is disposed on the top of the first support column. Fixing plates are fixedly connected to both sides between the top of the first support column and the top of the second support column. Protective side plates are fixedly connected to the top of both fixing plates. A material discharge channel is fixedly connected between the bottoms of the two fixing plates. A discharge bin is fixedly connected to the outer surface of the first support column near the top edge.

[0010] Preferably, two fixing frames are fixedly connected to the top of the first support column and the top of the second support column. Each fixing frame is rotatably connected to an auxiliary wheel, and the outer surfaces of each pair of auxiliary wheels are in contact with the outer surfaces of the two first fixing rings.

[0011] Preferably, two support plates are fixedly connected between the opposite outer surfaces of the first support column and the second support column. A mixing component is provided on the top of the two support plates. The mixing component includes a mixing chamber. A feeding port is fixedly connected to the top of one side of the mixing chamber. Limiting sleeves are fixedly connected to the opposite inner walls of the mixing chamber. Rotating blocks are rotatably connected to the inner walls of the two limiting sleeves. Rotating rods are fixedly connected between the opposite sides of the two rotating blocks. Multiple mixing mesh plates are fixedly connected to the outer surface of the rotating rods. A rotating hole is opened on one side of the inner wall of the mixing chamber.

[0012] Preferably, two positioning plates are fixedly connected between the inner walls of the second support column, and connecting bearings are fixedly connected to the inner walls of the two positioning plates. A rotating shaft is fixedly connected between the inner walls of the two connecting bearings. One end of the rotating shaft is fixedly connected to the outer surface of one of the rotating blocks, and the other end of the rotating shaft is rotatably connected to the inner wall of the rotating hole. A driven wheel is fixedly connected to the other end of the rotating shaft. A driven groove is formed on the outer surface of the driven wheel, and a conveyor belt is movably connected between the inner wall of the driven groove and the inner wall of the rotating groove.

[0013] A process for preparing dry-mixed mortar from all solid waste includes the following steps: The first step is to collect various types of solid waste, classify the collected waste, separate different types of waste, and crush them. The second step is to screen the crushed solid waste according to different particle sizes and dry the particles with higher moisture content. The third step involves mixing the pretreated solid waste with other additives, which requires a high proportion of fine aggregates and an appropriate amount of cement. The fourth step is to mix the prepared raw materials and ingredients to ensure that all raw materials are fully mixed to form a uniform dry-mixed mortar.

[0014] Preferably, the screening in the second step is carried out in a graded manner, which can separate solid waste particles of different sizes and collect qualified particles.

[0015] Preferably, the additives mentioned in the fourth step are waterproofing agents and air-entraining agents. The waterproofing agent can improve the impermeability of the mortar, and the air-entraining agent can introduce a large number of uniformly distributed micro-bubbles into the mortar, thereby improving the pore structure of the mortar.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. During use, the servo motor is started, which drives the drive wheel to rotate. The crushed raw material is fed into the second screen cylinder and rotates continuously. The raw material particles collide with the collision plate, breaking up the adhering particles. The fine particles are conveyed out through the feeding channel, while the larger particles remain between the first and second screen cylinders. The connection between the first and second screen cylinders is achieved through the connecting frame. The remaining raw material after screening is discharged through the discharge bin. The conveyor belt drives the fixed cover, driven wheel, and rotating rod to rotate, realizing the stirring effect of the mixing screen. It has a servo motor that drives both screening and mixing functions simultaneously, reducing energy consumption through linkage. By starting the air pump and energizing the heating coil, the airflow enters the second screen cylinder for screening through the fixed pipe and air supply pipe, thereby drying the raw material particles during screening. Thus, drying can be achieved simultaneously with screening, improving the preparation efficiency.

[0017] 2. During use, the servo motor drives the mixing chamber to rotate, which in turn drives the rotating shaft. The rotating shaft is connected to two positioning plates by two connecting bearings. By causing the rotating block to rotate inside the limiting sleeve, and because the rotating shaft is connected to the rotating block and the rotating rod, multiple mixing screens will rotate. By pouring the additives and cement into the mixing chamber from the feed port, the additives, cement and screened solid waste are mixed under the rotation of the mixing screens. The mixing operation can be completed without the need for additional drive equipment.

[0018] 3. When using it, first collect all kinds of solid waste, separate different types of waste, distinguish different components and properties, remove impurities such as wood, plastic, and metal, leaving only materials suitable for dry-mixed mortar preparation such as brick, stone, and concrete. Crush and screen the raw materials, and then dry them. Mix the crushed solid waste with the ingredients, and add waterproofing agents and air-entraining agents to the additives. The waterproofing agent is an organosilicon waterproofing agent, which can improve the impermeability of the mortar and prevent water from penetrating into the interior of the mortar, thereby improving its durability. The air-entraining agent can introduce a large number of evenly distributed micro air bubbles into the mortar, improve the pore structure of the mortar, improve its frost resistance and impermeability, and enhance the durability of the mortar. It can affect the service life of buildings made of dry-mixed mortar made from all solid waste. Mix the screened solid waste raw material particles with additives and cement to prepare dry-mixed mortar. Attached Figure Description

A second mesh cylinder 308 is fixedly connected between the inner walls of multiple connecting frames 303. A second fixing ring 311 is fixedly connected to both ends of the second mesh cylinder 308. Multiple second fixing strips 309 are evenly fixedly connected to the inner wall of the second mesh cylinder 308 along the circumferential direction. A collision plate 310 is fixedly connected to one side of each of the multiple second fixing strips 309. A fixing cover 312 is fixedly connected between one side of a first fixing ring 305 and one side of a second fixing ring 311. The drying assembly 4 includes a mounting frame 402. The outer surface of the mounting frame 402... An air pump 401 is installed on the surface. The output end of the air pump 401 is fixedly connected to a fixed pipe 403. One end of the fixed pipe 403 is fixedly connected to an air supply pipe 404. A heating coil 405 is installed on the inner wall of one end of the air supply pipe 404. A protective mesh plate 406 is fixedly connected to one end of the air supply pipe 404. A rotating groove 316 is opened on the outer surface of the fixed cover 312. A fixed bearing 313 is fixedly connected to the inner wall of the fixed cover 312. The inner wall of the fixed bearing 313 is fixedly connected to the outer surface of the air supply pipe 404. One side of one of the first fixed rings 305... A first connecting cylinder 304 is fixedly connected, a second connecting cylinder 307 is fixedly connected to one side of a second fixing ring 311, a limit ring 306 is fixedly connected to the outer surface of a first fixing ring 305, a drive wheel 315 is fixedly connected to the output shaft of a servo motor 314, the outer side of the drive wheel 315 is in contact with the outer side of the limit ring 306, and two support plates 103 are fixedly connected between the opposite outer surfaces of the first support column 101 and the second support column 102, and a mixing component 2 is provided on the top of the two support plates 103.

[0023] The support assembly 1 includes a first support column 101 and a second support column 102. A controller 7 is installed on the outer surface of the second support column 102. A servo motor 314 is installed on the top of the first support column 101. Fixing plates 104 are fixedly connected to both sides between the top of the first support column 101 and the top of the second support column 102. Protective side plates 105 are fixedly connected to the top of both fixing plates 104. A material discharge channel 6 is fixedly connected between the bottoms of the two fixing plates 104. A discharge bin 5 is fixedly connected to the outer surface of the first support column 101 near the top edge. Two fixing frames 106 are fixedly connected to the top of the first support column 101 and the top of the second support column 102. An auxiliary wheel 107 is rotatably connected inside each fixing frame 106. The outer surfaces of each pair of auxiliary wheels 107 are in contact with the outer surfaces of the two first fixing rings 305, respectively.

[0024] The working principle of this embodiment is as follows: During use, the controller 7 controls the start of the servo motor 314, causing its output shaft to rotate, which in turn drives the drive wheel 315 to rotate. Due to the close contact between the drive wheel 315 and the limiting ring 306, the friction is large, which drives the first fixed ring 305 and the first mesh cylinder 301 to rotate, feeding the crushed raw material into the second mesh cylinder 308. When the first mesh cylinder 301 and the second mesh cylinder 308 rotate, the solid waste raw material will continuously rotate inside the second mesh cylinder 308. The raw material particles will continuously collide with the collision plate 310, breaking up the adhering particles. The fine particles of raw material are conveyed out from the feeding channel 6. At this time, the two protective side plates 105 will block the raw material from splashing. Larger particles will remain between the first mesh cylinder 301 and the second mesh cylinder 308. The connecting frame 303 realizes the connection between the first mesh cylinder 301 and the second mesh cylinder 308. Next, the remaining raw materials after screening are discharged through the discharge bin 5. The first connecting cylinder 304 and the second connecting cylinder 307 can prevent the raw materials from spilling onto the servo motor 314. The conveyor belt 213 drives the fixed cover 312 and the driven wheel 210 to rotate, thereby driving the rotating rod 204 to rotate and realize the stirring effect of the mixing screen 205. A servo motor 314 drives screening and mixing simultaneously, reducing energy consumption through linkage. By starting the air pump 401 and energizing the heating coil 405, the airflow enters the second screen cylinder 308 for screening through the fixed pipe 403 and the air supply pipe 404, thereby drying the raw material particles in the screening. This allows for drying operations to be performed simultaneously with screening, improving preparation efficiency. In addition, multiple auxiliary wheels 107 are respectively set outside the two first fixed rings 305 to assist the rotation of the first screen cylinder 301.

[0025] Example 2: According to Figures 1-9As shown, two support plates 103 are fixedly connected between the opposite outer surfaces of the first support column 101 and the second support column 102. A mixing component 2 is provided on the top of the two support plates 103. The mixing component 2 includes a mixing chamber 201. A feed port 206 is fixedly connected to the top of one side of the mixing chamber 201. Limit sleeves 202 are fixedly connected to the opposite inner walls of the mixing chamber 201. Rotating blocks 203 are rotatably connected to the inner walls of the two limit sleeves 202. Rotating rods 204 are fixedly connected between the two rotating blocks 203. Multiple mixing mesh plates 205 are fixedly connected to the outer surface of the rotating rods 204. A section is opened on one side of the inner wall of the mixing chamber 201. Two positioning plates 207 are fixedly connected between the inner walls of the rotating hole 212 and the second support column 102. A connecting bearing 208 is fixedly connected to the inner wall of each positioning plate 207. A rotating shaft 209 is fixedly connected between the inner walls of the two connecting bearings 208. One end of the rotating shaft 209 is fixedly connected to the outer surface of one of the rotating blocks 203. One end of the rotating shaft 209 is rotatably connected to the inner wall of the rotating hole 212. A driven wheel 210 is fixedly connected to the other end of the rotating shaft 209. A driven groove 211 is opened on the outer surface of the driven wheel 210. A conveyor belt 213 is movably connected between the inner wall of the driven groove 211 and the inner wall of the rotating groove 316.

[0026] The working principle of this embodiment is as follows: During use, the servo motor 314 drives the mixing chamber 201 to rotate. The rotation of the mixing chamber 201 drives the rotating shaft 209 to rotate. At this time, the rotating shaft 209 is connected to the two positioning plates 207 through the connection of the two connecting bearings 208. By causing the rotating block 203 to rotate inside the limiting sleeve 202, and because the rotating shaft 209 is connected to the rotating block 203 and the rotating rod 204, multiple mixing screens 205 will be driven to rotate. By pouring the additives and cement into the mixing chamber 201 from the feed port 206, the additives, cement and screened solid waste are mixed under the rotation of the mixing screens 205. The mixing operation can be completed without the need for additional drive equipment.

[0027] Example 3: According to Figures 1-9 As shown, a process for preparing dry-mixed mortar from all solid waste includes the following steps: The first step is to collect various types of solid waste, classify the collected waste, separate different types of waste, and crush them. The second step is to screen the crushed solid waste according to different particle sizes and dry the particles with higher moisture content. The third step involves mixing the pretreated solid waste with other additives, which requires a high proportion of fine aggregates and an appropriate amount of cement. The fourth step is to mix the prepared raw materials and ingredients to ensure that all raw materials are fully mixed to form a uniform dry-mixed mortar.

[0028] The screening described in the second step is carried out in a graded manner, which can separate solid waste particles of different sizes and collect qualified particles. The additives described in the fourth step are waterproofing agents and air-entraining agents. The waterproofing agent can improve the impermeability of the mortar, and the air-entraining agent can introduce a large number of uniformly distributed micro air bubbles into the mortar, improving the pore structure of the mortar.

[0029] The working principle of this embodiment is as follows: First, various solid wastes, such as construction waste, industrial slag, and tailings, are collected. The collected solid wastes are then classified, separating different types of waste and distinguishing their different components and properties. For example, in construction waste, impurities such as wood, plastic, and metal are removed, leaving only materials suitable for dry-mixed mortar preparation, such as bricks, stones, and concrete. The raw materials are crushed and screened, then dried. The crushed solid waste is mixed with the additives. Waterproofing agents and air-entraining agents are added to the additives. The waterproofing agent is an organosilicon waterproofing agent, which improves the mortar's impermeability, preventing moisture penetration and thus enhancing its durability. The air-entraining agent introduces a large number of evenly distributed micro-bubbles into the mortar, improving its pore structure, enhancing its frost resistance and impermeability, and increasing its durability. This can affect the service life of buildings made from dry-mixed mortar made entirely of solid waste. The screened solid waste raw material particles are mixed with additives and cement to prepare the dry-mixed mortar.

[0030] In this invention, during use, the controller 7 controls the start of the servo motor 314, causing its output shaft to rotate, which in turn drives the drive wheel 315 to rotate. Due to the close contact between the drive wheel 315 and the limiting ring 306, the friction is high, thereby driving the first fixing ring 305 and the first mesh cylinder 301 to rotate, and the crushed raw material is put into the second mesh cylinder 308. When the first mesh cylinder 301 and the second mesh cylinder 308 rotate, the solid waste raw material will continuously rotate inside the second mesh cylinder 308, and the raw material particles will continuously collide with the collision plate 310. The adhering particles are broken up, and the fine particles are conveyed out from the feeding channel 6. At this time, the two protective side plates 105 will block the raw material from splashing, and the larger particles will remain in the first mesh cylinder 301 and the second mesh cylinder. Between 308, the first screen cylinder 301 and the second screen cylinder 308 are connected by a connecting frame 303. The remaining raw material after screening is discharged through the discharge bin 5. The first connecting cylinder 304 and the second connecting cylinder 307 can prevent the raw material from spilling onto the servo motor 314. The conveyor belt 213 drives the fixed cover 312 and the driven wheel 210 to rotate, thereby driving the rotating rod 204 to rotate and realize the stirring effect of the mixing screen plate 205. One servo motor 314 drives screening and mixing simultaneously, and the linkage reduces energy consumption. By starting the air pump 401 and energizing the heating coil 405, the airflow enters the second screen cylinder 308 for screening through the fixed pipe 403 and the air supply pipe 404. In addition, multiple auxiliary wheels 107 respectively It is set outside the two first fixed rings 305 to assist the rotation of the first mesh cylinder 301. In use, driven by the servo motor 314, the mixing chamber 201 is rotated. The rotation of the mixing chamber 201 drives the rotating shaft 209 to rotate. At this time, the rotating shaft 209 is connected to the two positioning plates 207 through the connection of the two connecting bearings 208. By causing the rotating block 203 to rotate inside the limiting sleeve 202, and because the rotating shaft 209 is connected to the rotating block 203 and the rotating rod 204, multiple mixing mesh plates 205 will be rotated. By pouring the additives and cement into the mixing chamber 201 from the feed port 206, the additives, cement and screened solid waste are mixed under the rotation of the mixing mesh plates 205. In use, First, various types of solid waste, such as construction waste, industrial slag, and tailings, must be collected. The collected solid waste must be classified, separating different types and distinguishing their different components and properties. For example, in construction waste, impurities such as wood, plastic, and metal must be removed, leaving only materials suitable for dry-mixed mortar preparation, such as bricks, stones, and concrete. The raw materials are then crushed and screened, and dried. The crushed solid waste is mixed with the additives, and waterproofing agents and air-entraining agents are added. Organosilicon waterproofing agents are chosen to improve the mortar's impermeability, preventing moisture from penetrating into the mortar and thus improving its durability. Air-entraining agents introduce a large number of evenly distributed micro-bubbles into the mortar, improving its pore structure.The screened solid waste raw material particles are mixed with additives and cement to prepare dry-mixed mortar.
