Description

Technical Field

[0001] The invention belongs to the technical field of solid waste material preparation, and in particular relates to a device for preparing multi-solid waste-based gelling material. Background Art

[0002] With the acceleration of industrial development and urbanization, various types of solid waste (such as slag, fly ash, steel slag, construction waste, etc.) are generated in large quantities, which imposes a heavy burden on the environment. Multi-solid waste-based cementitious materials use a variety of solid wastes as the main raw materials. Through reasonable proportioning and treatment, they can realize the resource utilization of solid wastes and produce products with excellent performance that can replace traditional cement and other cementitious materials; After checking, the public (announcement) number: CN202321548400.7 discloses a solid waste-based cementitious material pretreatment device for wall panels. This technology discloses "a solid waste-based cementitious material pretreatment device for wall panels, including a base, the bottom of the base is fixedly connected to a support leg, the bottom right side of the base is fixedly connected to a connecting block and other technical contents, and discloses that the solid waste-based cementitious material pretreatment device for wall panels can grind and crush large pieces of material by setting a screening barrel, a crushing disc, a hydraulic rod, a screen, etc. to cooperate with each other, so that the fine material can be crushed and the qualified size of the material can be screened out through the screening barrel, thereby improving the work efficiency and enhancing the preparation effect and other technical effects"; However, in actual use, since the aperture on the surface of the screening barrel is fixed, this design can only produce products with relatively consistent particle sizes in actual production. However, different engineering sites and performance requirements have different requirements for the particle size of solid waste-based cementitious materials. When it is necessary to produce solid waste-based cementitious materials with various particle sizes, the fixed screening barrel cannot be adjusted immediately during the production process, and production needs to be stopped and the entire screening equipment needs to be replaced or additional screening steps need to be taken to separate products with the required particle size. This not only increases the time for equipment replacement and debugging, but may also cause production process interruptions and reduce overall production efficiency.

The process is cumbersome and time-consuming, resulting in idle equipment and production interruption.

With the cooperation of components such as wedge-shaped limiters and wedge-shaped grooves, the grinding disc conversion is completed within a few minutes, and the subsequent production is quickly connected, reducing downtime, significantly improving the overall production efficiency, and the rhythm of continuous industrial production, and the output per unit time can be increased.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The grinding and crushing components are provided, and the grinding cover, guide pipe, connecting sleeve, spring, T-shaped connecting slide rod, grinding roller and grinding disc are used in coordination. The grinding roller fits tightly against the grinding disc under the elastic force of the spring to grind the raw materials. During this process, the grinding cover on the surface of the rotating mounting disc effectively covers the grinding roller to prevent the material from splashing. The powder generated by grinding is reasonably guided through the guide pipe and the grinding cover to ensure that the material is circulated and ground in an orderly manner in the grinding area. Spring 1 enables the grinding roller to adaptively adjust the pressure on the grinding disc. During the grinding process, as the size and hardness of the raw material particles change, different grinding pressures are required to ensure the best grinding effect. When encountering larger particles or higher hardness raw materials, the reaction force on the grinding roller increases, and Spring 1 is compressed, thereby increasing the pressure of the grinding roller on the grinding disc, so that the grinding force can effectively crush and grind these more difficult to handle raw materials. On the contrary, when grinding finer or softer raw materials, the elastic force of Spring 1 can keep the grinding roller at an appropriate grinding pressure. This stable contact can ensure that the pressure in the grinding area is evenly distributed, improve the uniformity and consistency of grinding, and is conducive to obtaining products with uniform particle size.

[0016] 2. By setting up a grinding replacement component, through the coordinated use of the L-shaped fixed sleeve rod, spring 2, wedge-shaped limiter, fixed disk, wedge-shaped groove, fixed ring, T-shaped ball head limiter rod and ball head limiter groove and other structures, when the size of the grinding particles needs to be changed according to the actual processing needs, it can be quickly adapted and adjusted so that the grinding disk with the corresponding aperture on the surface of the installed rotating mounting disk corresponds to the bottom end of the grinding cover, which can accurately meet the differentiated requirements of multiple applications for the particle size of solid waste-based cementitious materials, and produce accurate products adapted to different scenarios by conveniently switching the grinding disk. Granular products avoid the impact of substandard particle size on material properties and improve the quality of cementitious materials. Compared with traditional processes that often require shutdown, disassembly of equipment, and replacement of a whole set of grinding parts to change particle size, which are cumbersome and time-consuming, resulting in idle equipment and production interruptions, this device does not require complicated disassembly. The servo motor reverses and instantly starts the switching process. With the coordination of components such as wedge-shaped limiters and wedge-shaped grooves, the grinding disc conversion is completed within minutes, quickly connecting to subsequent production, reducing downtime, and significantly improving overall production efficiency and continuous industrial production rhythm. The output per unit time can be increased.

[0017] 3. A grinding and cleaning component is provided, and the wavy spiral grooves, connecting slide rods, connecting discs, T-shaped connecting rods, spring four, plug-in discs and ejector rods are used in coordination with each other. As the transmission shaft rotates, the wavy spiral grooves on its surface drive the connecting slide rods to reciprocate up and down, and the connecting slide rods drive the connecting discs and the T-shaped connecting rods to move together, so that the plug-in discs move downward, and the ejector rods are inserted into the aperture of the grinding disc to poke out and clean the material particles blocked in the aperture during the grinding process. The cleaned material is discharged separately through the set discharge pipe and will not be mixed with the ground material, thereby ensuring that the aperture of the grinding disc is unobstructed, which is conducive to continuous and efficient grinding and avoids a sharp increase in grinding resistance and a sudden drop in efficiency due to aperture blockage.

[0018] 4. By setting up a pre-processing component, through the coordinated use of the structures such as the crushing box, the hinged sleeve rod, the yield sleeve, the spring five, the T-shaped rod, the crushing clamp, the baffle bar and the extrusion block, a movable crushing clamp connected to the T-shaped rod is made to open and close relative to the other crushing clamp fixed in the crushing box. When the two crushing clamps are close to each other, the input raw materials can be crushed to crush the large-particle block raw materials into smaller particles. When the crankshaft section pushes the articulated sleeve rod to quickly close the crushing clamp, the spring five can absorb part of the impact force to prevent the crushing clamp from violently colliding with the fixed crushing clamp or the inner wall of the crushing box, thereby reducing the noise generated during the operation of the equipment and extending the service life of the equipment. At the same time, the spring five can provide additional extrusion force for the crushing clamp during the crushing process. When the crushing clamp begins to close and squeeze the solid waste raw materials, the spring five is compressed, and the elastic potential energy stored in it will be gradually released as the crushing clamp closes, increasing the extrusion force of the crushing clamp on the raw materials. This elastic assist can make the crushing clamp better adapt to solid waste raw materials of different hardness and size, and can ensure that the crushing clamp exerts sufficient pressure to crush them, thereby improving the crushing efficiency and quality. The set baffles can intercept raw materials with diameters larger than the distance between two adjacent baffles, so that these larger raw materials are intercepted on the surface of the baffles, and then the extrusion blocks crush them in a targeted manner when the crushing clamps are closed. This method can prevent the raw materials from rolling randomly in the crushing box, resulting in some raw materials not being effectively crushed, ensuring that all raw materials can be crushed within the expected size range and can be crushed into suitable particle sizes, providing raw materials with relatively uniform particle sizes for subsequent grinding processes.

The material guide pipe 26 is fixedly installed on the inner top surface of the preparation box 1. The grinding cover 25 is sleeved on the outer side of the grinding roller 210, and the connecting sleeve 27 is rotatably connected to the surface of the grinding cover 25.

[0027] According to actual processing needs, when the size of the grinding particles needs to be changed, the servo motor 22 is controlled to reverse, and at this time, the wedge-shaped limiter 33 elastically connected to the L-shaped fixed sleeve rod 31 through the spring 2 32 will be stuck in the wedge-shaped groove 35 opened on the surface of the fixed disk 34, and the fixed disk 34 drives the rotating mounting disk 212 to rotate on the surface of the fixed partition 211 until the grinding disk 213 with the corresponding aperture on the surface of the installed rotating mounting disk 212 corresponds to the bottom end of the grinding cover 25, which can accurately meet the differentiated requirements of multiple applications for the particle size of solid waste-based cementitious materials.

[0030] Embodiment 3 In addition to all the technical features of the first embodiment, this embodiment also includes: A grinding and cleaning assembly 4 is installed inside the preparation box 1, and the grinding and cleaning assembly 4 includes a wavy spiral groove 41, a connecting slide rod 42, a sliding protrusion 43, a connecting plate 44, a T-shaped connecting rod 45, a spring 46, a plug plate 47, a plug-in rod 48, a limiting sleeve 49, a limiting rod 410 and a discharge pipe 411; A plug-in disk 47 is provided inside the preparation box 1, and a plug-in rod 48 is integrally formed on the bottom surface of the plug-in disk 47.

The cleaned material is discharged separately through the set discharge pipe 411 and will not be mixed with the ground material, thereby ensuring that the aperture of the grinding plate 213 is unobstructed, which is conducive to continuous and efficient grinding and avoids a sharp increase in grinding resistance and a sudden drop in efficiency due to aperture blockage.

The diameter of the ejector rod 48 is smaller than the grinding aperture of the grinding disk 213 with a smaller aperture so that each grinding disk 213 can be cleared and prevented from being blocked.

[0034] Embodiment 4 In addition to all the technical features of the first embodiment, this embodiment also includes: The surface of the preparation box 1 is provided with a pretreatment assembly 5, which includes a crushing box 51, a crankshaft section 52, an articulated sleeve rod 53, a yield sleeve 54, a spring five 55, a T-shaped rod 56, a fixed yield sleeve 57, a crushing clamp 58, a stop bar 59, an extrusion block 510, a T-shaped limiting guide rod 511 and a spring six 512; A crushing box 51 is fixedly installed on the surface of the preparation box 1, and two crushing clamps 58 are symmetrically arranged in the crushing box 51.

A spring 55 is installed in the yield sleeve 54, and one end of the spring 55 abuts against one end of a T-shaped rod 56 slidably connected in the yield sleeve 54. A fixed yield sleeve 57 is slidably connected to the outer side of the yield sleeve 54, and one end of the fixed yield sleeve 57 is installed on one side of the crushing box 51. One end of the T-shaped rod 56 passes through the crushing box 51 and is connected to one of the crushing clamps 58 slidably connected in the crushing box 51. The other crushing clamp 58 is fixedly installed in the crushing box 51, and the bottom of the crushing box 51 is connected to the guide pipe 26.

[0035] A movable crushing clamp 58 connected to the T-shaped rod 56 is prompted to open and close relative to another crushing clamp 58 fixed in the crushing box 51. When the two crushing clamps 58 are close to each other, the input raw materials can be crushed to crush large particles into smaller particles. The provided baffles 59 can intercept raw materials whose diameter is larger than the distance between two adjacent baffles 59, so that these larger raw materials are intercepted on the surface of the baffles 59, and then the extrusion block 510 specifically crushes them when the crushing clamp 58 is closed. This method can prevent the raw materials from rolling randomly in the crushing box 51, resulting in some raw materials not being effectively crushed, ensuring that all raw materials can be crushed within the expected size range, and can be crushed into a suitable particle size, providing raw materials with relatively uniform particle size for subsequent grinding processes; During the crushing process, the T-shaped limit guide rod 511 regulates the moving trajectory of the crushing clamp 58 with the assistance of the spring six 512 to ensure stable crushing action. The crushed raw materials fall into the grinding area through the bottom of the crushing box 51 through the guide pipe 26.

[0036] A T-shaped limit guide rod 511 is slidably connected in the through hole opened on the surface of the crushing box 51, and a spring 6 512 is sleeved on the surface of the T-shaped limit guide rod 511. One end of the T-shaped limit guide rod 511 passes through the crushing box 51 and is connected to the movable crushing clamp 58. A plurality of baffle bars 59 are installed at equal intervals inside the crushing box 51 and on the bottom surface of the crushing clamp 58. A plurality of extrusion blocks 510 are installed at equal intervals on the bottom surface of the crushing clamp 58, and the extrusion blocks 510 extend to the bottom of the baffle bar 59.

[0037] The working principle and use process of the present invention: when the preparation device is used, the servo motor 22 is first controlled to rotate, and then the transmission shaft 23 installed at the output shaft end of the servo motor 22 can be rotated, and the crankshaft section 52 on the surface of the transmission shaft 23 rotates, and drives the articulated sleeve rod 53 to do reciprocating motion, and the articulated sleeve rod 53 pulls the clearance sleeve 54 and the T-shaped rod 56, so that a movable crushing clamp 58 connected to the T-shaped rod 56 is relatively opened and closed relative to another crushing clamp 58 fixed in the crushing box 51. When the two crushing clamps 58 are close to each other, the input raw materials can be crushed to crush large particles into smaller particles; During the opening and closing process of the crushing clamp 58, due to the movement of the crankshaft section 52, the force transmitted to the yield sleeve 54 and the T-shaped rod 56 through the hinged sleeve rod 53 is intermittent and has impact force. The spring 55 can effectively buffer this impact force and reduce the vibration of the equipment caused by the sudden change of force. When the crankshaft section 52 pushes the hinged sleeve rod 53 to quickly close the crushing clamp 58, the spring 55 can absorb part of the impact force to avoid the crushing clamp 58 from violently colliding with the fixed crushing clamp 58 or the inner wall of the crushing box 51, thereby reducing the noise generated during the operation of the equipment and extending the service life of the equipment. At the same time, the spring 55 can provide additional squeezing force for the crushing clamp 58 during the crushing process. When the crushing clamp 58 begins to close and squeeze the solid waste raw materials, the spring 55 is compressed, and the elastic potential energy stored in it will be gradually released as the crushing clamp 58 closes, increasing the squeezing force of the crushing clamp 58 on the raw materials. This elastic assist can make the crushing clamp 58 better adapt to solid waste raw materials of different hardness and size, and can ensure that the crushing clamp 58 applies sufficient pressure to crush them, thereby improving the crushing efficiency and quality. The provided baffles 59 can intercept raw materials whose diameter is larger than the distance between two adjacent baffles 59, so that these larger raw materials are intercepted on the surface of the baffles 59, and then the extrusion block 510 specifically crushes them when the crushing clamp 58 is closed. This method can prevent the raw materials from rolling randomly in the crushing box 51, resulting in some raw materials not being effectively crushed, ensuring that all raw materials can be crushed within the expected size range, and can be crushed into a suitable particle size, providing raw materials with relatively uniform particle size for subsequent grinding processes; During the crushing process, the T-shaped limit guide rod 511 regulates the moving trajectory of the crushing clamp 58 with the assistance of the spring six 512 to ensure stable crushing action, and the crushed raw materials fall into the grinding area through the bottom of the crushing box 51 through the guide pipe 26; The pre-treated raw material falling into the grinding area reaches the surface of the rotating mounting plate 212. At this time, the servo motor 22 continuously drives the transmission shaft 23, and drives the connecting sleeve 27 and the connected grinding roller 210 to rotate through the sprocket transmission group 24. The grinding roller 210 is tightly attached to the grinding plate 213 under the elastic force of the spring 28 to grind the raw material. In this process, the grinding cover 25 on the surface of the rotating mounting plate 212 effectively covers the grinding roller 210 to prevent the material from splashing. The powder generated by grinding is reasonably guided through the material guide pipe 26 and the grinding cover 25 to ensure that the material is circulated and ground in the grinding area in an orderly manner. The grinding roller 210 is elastically abutted against the surface of the grinding disc 213 by a spring 28. The spring 28 enables the grinding roller 210 to adaptively adjust the pressure on the grinding disc 213. During the grinding process, as the size and hardness of the raw material particles change, different grinding pressures are required to ensure the best grinding effect. When encountering larger particles or raw materials with higher hardness, the reaction force on the grinding roller 210 increases, and the spring 28 is compressed, thereby increasing the pressure of the grinding roller 210 on the grinding disc 213, so that the grinding force can effectively crush and grind these more difficult-to-handle raw materials. On the contrary, when grinding finer or softer raw materials, the elastic force of the spring 28 can keep the grinding roller 210 at an appropriate grinding pressure. This stable contact can ensure that the pressure in the grinding area is evenly distributed, improve the uniformity and consistency of grinding, and is conducive to obtaining products with uniform particle sizes. According to actual processing needs, when the size of the grinding particles needs to be changed, the servo motor 22 is controlled to reverse, and at this time, the wedge-shaped limiter 33 elastically connected to the L-shaped fixed sleeve rod 31 through the spring 2 32 will be stuck in the wedge-shaped groove 35 opened on the surface of the fixed disk 34, and the fixed disk 34 drives the rotating mounting disk 212 to rotate on the surface of the fixed partition 211 until the grinding disk 213 with the corresponding aperture on the surface of the installed rotating mounting disk 212 corresponds to the bottom end of the grinding cover 25, which can accurately meet the differentiated requirements of multiple applications for the particle size of solid waste-based cementitious materials. By conveniently switching the grinding disk 213, the output Precise particle size products adapted to different scenarios avoid affecting material performance due to substandard particle size and improve the quality of cementitious materials. Compared with the traditional process, if the particle size needs to be changed, it is often necessary to shut down, disassemble the equipment, and replace the entire set of grinding parts. The process is cumbersome and time-consuming, resulting in idle equipment and production interruption. This device does not require complicated disassembly. The servo motor 22 reverses and instantly starts the switching process. With the cooperation of components such as the wedge-shaped limiter 33 and the wedge-shaped groove 35, the grinding disc 213 is switched within a few minutes, quickly connecting to subsequent production, reducing downtime, significantly improving overall production efficiency, continuous industrial production rhythm, and increasing output per unit time; When the servo motor 22 rotates forward, the wedge-shaped stopper 33 will only slide on the surface of the fixed disk 34, and the wedge-shaped stopper 33 will not be stuck in the wedge-shaped groove 35. At the same time, the T-shaped ball stopper rod 37 is stably inserted into the ball stopper groove 310 on the bottom surface of the rotating mounting disk 212 under the elastic force of the spring 38 to fix the adjusted position. The rotating mounting disk 212 will not rotate on the surface of the fixed partition 211, which can ensure the stability of the raw material when it is crushed by the corresponding grinding disk 213. As the transmission shaft 23 rotates, the wavy spiral grooves 41 on its surface drive the connecting slide bar 42 to make up and down reciprocating motions, and the connecting slide bar 42 drives the connecting plate 44 and the T-shaped connecting rod 45 to move in conjunction, so that the plug-in plate 47 moves downward, and the plug-in rod 48 is inserted into the aperture of the grinding plate 213 to poke out and clean the material particles blocked in the aperture during the grinding process. The cleaned material is discharged separately through the set discharge pipe 411 and will not be mixed with the ground material, thereby ensuring that the aperture of the grinding plate 213 is unobstructed, which is conducive to continuous and efficient grinding, and avoiding a sharp increase in grinding resistance and a sudden drop in efficiency due to aperture blockage; The ejector rod 48 cooperates with the spring four 46. When the ejector rod 48 cleans the aperture of the grinding disc 213, the spring four 46 can play a buffering role. When the ejector rod 48 encounters a large resistance, the spring four 46 will be compressed to prevent the ejector rod 48 and the grinding disc 213 from being damaged due to rigid collision, thereby protecting the ejector rod 48 and the grinding disc 213. Different aperture sizes and shapes of grinding discs 213 may have certain differences, and in the actual grinding process, the degree of material blockage may also vary. The spring four 46 can enable the ejector rod 48 to adapt to these changes. When the aperture is small or the blockage is light, the insertion depth of the ejector rod 48 may be shallow. At this time, the compression amount of the spring four 46 is small. When the aperture is large or the blockage is serious, the ejector rod 48 can penetrate deep into the aperture for cleaning under the elastic force of the spring four 46, ensuring that blockages in different situations can be effectively handled. This can improve the versatility and cleaning effect of the ejector rod 48 and adapt to a variety of complex grinding conditions. The ground material that falls into the feeding port of the conveying auger 214 is conveyed axially toward the discharging port as the spiral blades of the conveying auger 214 rotate, so that the material is transferred from the grinding area to the next process or collection device. During this process, the outer fixing ring 36 and related components of the conveying auger 214 play a role, and the T-shaped ball head limiting rod 37 is stably inserted into the ball head limiting groove 310 on the bottom surface of the rotating mounting disk 212 under the elastic force of the spring three 38, so as to ensure the relative position stability of the conveying auger 214 and the rotating mounting disk 212, and prevent material leakage and equipment operation deviation.

[0038] It should be noted that inert gas (such as nitrogen) can be introduced during the grinding and material transportation process to prevent some easily oxidizable materials (such as metal tailings powder) from oxidation and deterioration.

[0039] It should be noted that the sprocket drive group 24 is mainly composed of a driving sprocket, a driven sprocket and a chain. The driving sprocket is installed on the transmission shaft 23, and the driven sprocket is connected to the connecting sleeve 27. The chain is a transmission component connecting the driving sprocket and the driven sprocket, and it transmits power between the sprockets.
