Abstract
Description
Technical Field
[0001] The invention relates to the technical field of environmentally friendly building material preparation, in particular to a preparation device and a preparation process of clinker-free cement. Background Art
[0002] Clinker-free cement is made by mixing active materials (such as granulated blast furnace slag, fly ash, volcanic ash, steel slag, etc.) and alkaline activators (such as lime, etc.) or sulfate activators (such as gypsum) or other chemical activators in proportion and grinding them into powder. In the production of clinker-free cement, not only the main raw materials can be industrial solid waste, but also the activators can be solid waste, such as desulfurized gypsum instead of natural gypsum. Therefore, the production of clinker-free cement can realize the resource utilization of industrial solid waste. Granulated blast furnace slag is a by-product produced during iron smelting. Its main components are silicates and aluminosilicates. It has a certain degree of hydraulic hardness, so it is widely used in the field of building materials.
[0003] When using industrial solid waste such as blast furnace slag as the main raw material to prepare clinker-free cement, the slag must first be crushed into pieces, and then the pieces must be ground to achieve the conditions for making clinker-free cement. In the process of crushing and grinding the slag, a large amount of dust will appear. The generation of dust will not only cause environmental pollution to the outside world, but also easily cause damage to the device itself due to long-term accumulation, thereby reducing the service life of some parts in the device.
[0004] Moreover, when slag is used as one of the main raw materials and added to the production process of clinker-free cement, the ratio between the slag powder and other raw materials cannot be accurately controlled. Moreover, when the crushed slag is ground, the ground slag powder cannot be evenly added to other solid wastes that are being stirred and mixed. Directly adding it is likely to cause accumulation of slag powder and uneven mixing, which affects the production quality of cement. Moreover, when the slag is ground, not only a large amount of smoke and dust will appear, but also incomplete grinding will occur. Large-volume slag cannot be ground into powder quickly and stably, and secondary grinding is required, which will reduce work efficiency. Therefore, a preparation device and a preparation process of clinker-free cement are proposed. Summary of the invention

[0016] Preferably, the present invention also proposes a preparation process of a preparation device for clinker-free cement, and the process steps are as follows:
[0017] S1: Crushing and screening: The first motor drives the rotating shaft to rotate, and the rotating shaft drives the crushing shaft to rotate through the first gear set. The crushing shaft drives two sets of crushing blades to crush the slag. At the same time, the crushing shaft drives the push plate to rotate through the second gear set. The push plate rotates through the inclined surface to push the folding rod at one end of the sliding column to reciprocate. The folding rod drives two sets of screens through the connecting plate to screen the crushed slag.
[0018] S2: Dust removal and material discharge: The folding rod drives the first piston rod on one side of the connecting rod to slide inside the first piston cylinder, which can collect the dust generated by screening and crushing. At the same time, the movement of the screen will drive the fixed column to contact the convex block inside the screening bin, so that the screen moves and vibrates at the same time, which can make the crushed and screened slag evenly fall onto the surface of the grinding plate for uniform grinding;
[0019] S3: Multi-stage grinding: The wedge plate is driven to move by the movement of the mobile frame. The wedge plate pushes the through plate at one end of the push rod to reciprocate through the inclined surface. The movement of the through plate drives multiple sets of grinding wheels to roll and grind the crushed and screened slag. The ground slag powder will fall into the inside of the grinding cylinder. The fixed plate driven by the transmission shaft rotates, and the fixed plate drives the grinding rod to rotate inside the grinding cylinder to grind the slag powder again. At the same time, the opposite rotation of the two sets of curved rotating plates can squeeze and grind the slag powder and other raw materials and activators again;
[0020] S4: Raw material mixing: The moving plate is driven to move above the bottom plate by the moving frame. Since there is a gap between the moving plate and the bottom plate, the slag powder and other raw materials and activators can be preliminarily mixed, and the slag powder and the raw materials and activators can be ground again.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] 1. The present invention drives the rotating shaft to rotate by the rotation of the first motor, and the rotation of the rotating shaft drives the first gear set and the crushing shaft to rotate. The rotation of the crushing shaft can drive the two groups of crushing leaves to crush the slag. At the same time, the rotation of the crushing shaft will drive the second gear set to rotate. The rotation of the second gear set can drive the push plate to rotate. While the push plate rotates, the sliding column is pushed to reciprocate left and right through the inclined surface. The movement of the sliding column will drive the two groups of screens to reciprocate left and right through the connecting plate at one end of the folding rod, which can screen the crushed slag and make the crushed slag evenly fall into the interior of the grinding bin, so that the slag can be fully ground. At the same time, when the folding rod moves, it will also drive the first piston rod to slide inside the first piston cylinder through the connecting rod, so that the dust generated during crushing and screening can be collected into the interior of the collecting bag, which can avoid damage to the external environment and reduce the damage to the device caused by dust.
[0023] 2. The present invention drives the first belt to rotate through the pulley on the surface of the crushing shaft, and the first belt drives the transmission shaft to rotate through the transmission pulley. The rotation of the transmission shaft can drive the incomplete gear to rotate, and the rotation of the incomplete gear can mesh with the transmission to drive the rack to reciprocate back and forth. The reciprocating motion of the rack can drive the wedge plate above the movable frame to move. When the wedge plate moves, it will push the push rod to reciprocate left and right inside the grinding bin through the inclined surface. When the push rod moves, it will drive the grinding wheel to perform primary grinding of the crushed slag through the through plate. At the same time, the multiple groups of rubbing rods driven by the through plate can make the crushed slag fall evenly to the position of the grinding wheel, so that it can be roller-ground, which can effectively avoid the accumulation of slag during the grinding process and has high working efficiency.
[0024] 3. The present invention drives the fixed plate to rotate by the rotation of the transmission shaft. When the fixed plate rotates, it will drive multiple groups of grinding rods to rotate inside the grinding cylinder. Since the surface of the grinding cylinder is provided with through holes, when the grinding rods rotate to a position without through holes, and the inner surface of the grinding cylinder and the surface of the grinding rods are both made of materials with good friction, the grinding rods will rotate while following the rotation of the fixed plate, so that the slag after roller grinding by the grinding wheel can be ground again. At the same time, the rotation of the grinding rods will also drive the matching shaft to rotate through the pulley. The rotation of the matching shaft will drive the two groups of curved rotating plates to rotate forward and reverse through the third gear set. The rotation of the two groups of curved rotating plates can not only perform the initial mixing of slag powder and solid waste, but also perform extrusion grinding between the slag powder and the solid waste, which can further improve the quality of slag powder grinding.
[0025] 4. The present invention drives the movement of the magnetic block through the reciprocating motion of the rack. The movement of the magnetic block will magnetically drive the blocking plate to move at the discharge port position of the through plate, so as to seal and open the discharge port, control the ratio between the slag powder and other raw materials and stimulants, and avoid excessive addition of other raw materials and stimulants to affect the production quality of non-clinker cement. At the same time, when the slag powder and other raw materials and stimulants fall to the surface of the bottom plate through the through holes on the surface of the moving plate, the movement of the moving plate can mix, stir and grind the slag powder and other raw materials and stimulants again, so as to fully mix the other raw materials and stimulants with the slag powder. At the same time, the movement of the movable frame can also push the second piston rod to slide inside the second piston cylinder through the convex plate, and can transport part of the raw materials to the surface of the moving plate through the connecting hose, so that the slag powder and other raw materials between the moving plate and the bottom plate are pre-mixed, which is convenient for the subsequent auger rod to stir, mix and form them.

[0056] Furthermore, a convex plate 304 is fixedly connected to the bottom of the movable frame 206, and one side of the convex plate 304 is in sliding contact with a second piston rod 308, and the surface of the second piston rod 308 is slidably connected to a second piston cylinder 309, and the surface of the second piston cylinder 309 is fixedly connected to a storage box 305 and a connecting hose 310, and the other end of the connecting hose 310 is fixedly connected to an arc plate 311, and a discharge hole is provided on the surface of the arc plate 311, and the arc plate 311 is fixedly connected to one side of the movable plate 306, and a dryer 5 is also provided on the inner side of the working box 1, and one side of the dryer 5 is connected to the grinding bin 9 through the inside of the air inlet pipe 6.
[0057] Among them, by setting up the dryer 5, the moisture contained in the slag powder and solid waste can be evaporated, which can prevent the slag powder from adhering to the surface of the device. At the same time, through the setting of the second piston rod 308 and the second piston cylinder 309, part of the raw materials or stimulants can be intermittently transported to the surface of the moving plate 306, so that they can be fully pre-mixed with the slag powder and solid waste, which can improve the efficiency of the auger rod 303 in stirring and mixing the clinker-free cement.
[0058] Furthermore, the present invention also proposes a preparation process of a device for preparing clinker-free cement, and the process steps are as follows:
[0059] S1: Crushing and screening: The first motor 101 rotates to drive the rotating shaft 102 to rotate, and the rotating shaft 102 drives the crushing shaft 118 to rotate through the first gear set 103. The crushing shaft 118 drives two groups of crushing leaves 115 to crush the slag. At the same time, the crushing shaft 118 drives the push plate 106 to rotate through the second gear set 105. The push plate 106 rotates and pushes the folding rod 108 at one end of the sliding column 107 to reciprocate through the inclined surface. The folding rod 108 drives two groups of screens 109 through the connecting plate 116 to screen the crushed slag;
[0060] S2: Dust removal and material discharge: The folding rod 108 drives the first piston rod 111 on one side of the connecting rod 110 to slide inside the first piston cylinder 112, so that the dust generated by screening and crushing can be collected. At the same time, the movement of the screen 109 drives the fixed column 117 to contact the protrusion 114 inside the screening bin 8, so that the screen 109 moves and vibrates at the same time, so that the crushed and screened slag can be evenly dropped onto the surface of the grinding plate 214 for uniform grinding;
[0061] S3: Multi-stage grinding: The wedge plate 207 is driven to move by the movement of the moving frame 206. The wedge plate 207 pushes the through plate 210 at one end of the push rod 209 to reciprocate through the inclined surface. The movement of the through plate 210 drives multiple groups of grinding wheels 212 to perform roller grinding on the crushed and screened slag. The ground slag powder will fall into the inside of the grinding cylinder 218. The fixed plate 213 driven by the transmission shaft 201 rotates. The fixed plate 213 drives the grinding rod 219 to rotate inside the grinding cylinder 218, which can grind the slag powder again. At the same time, the opposite rotation of the two groups of curved rotating plates 217 can squeeze and grind the slag powder and other raw materials and activators again.
[0062] S4: Raw material mixing: The moving plate 306 is driven to move above the bottom plate 307 by the movable frame 206. Since there is a gap between the moving plate 306 and the bottom plate 307, the slag powder and solid waste can be preliminarily mixed, and the slag powder, raw materials and activator can be ground again.
[0063] Working principle: After the present invention is installed, firstly, the solid waste for making clinker-free cement is added to the interior of the storage box 10, and then part of the raw materials or activators for mixing are added to the interior of the storage box 305, and then a new collecting capsule 113 is installed on the surface of the first piston cylinder 112, and then an appropriate amount of slag to be crushed and ground is placed in the interior of the lower hopper 3, and then the cover plate 2 is closed and the first motor 101 is opened to rotate and drive the crushing shaft 118 to rotate, and the rotation of the crushing shaft 118 can drive the crushing leaves 115 to rotate, and when the crushing shaft 118 rotates, it will drive another group of crushing leaves 115 to rotate through the first gear set 103. At this time, the rotation of the two groups of crushing leaves 115 can crush the slag, which is convenient for the subsequent grinding of smaller slag. While crushing the slag, the dryer 5 is started to blow hot air into the grinding bin 9, which can dry the slag being crushed and the smaller slag to be ground subsequently, so as to avoid the slag adhering to the surface of the crushing leaves 115 due to the high moisture content during crushing, thereby affecting the quality of subsequent slag crushing;
[0064] When the two groups of crushing leaves 115 are crushing the slag, the rotation of the first gear group 103 can drive the second gear group 105 to rotate, and the second gear group 105 will drive the push plate 106 to rotate. Since one side of the push plate 106 is inclined at a certain angle, when the push plate 106 rotates, it can push the slide post 107 to reciprocate left and right. The movement of the slide post 107 will drive the two groups of screens 109 to reciprocate left and right inside the screening bin 8 through the connecting plate 116 connected to one end of the folding rod 108. The reciprocating movement of the two groups of connecting plates 116 can not only screen the crushed slag, but also facilitate the subsequent staff to collect the larger slag, and at the same time, it can make the crushed smaller slag evenly fall onto the surface of the grinding plate 214 below, which can avoid the accumulation of slag when being ground, affecting the efficiency and quality of slag grinding.
[0065] When the two groups of screens 109 reciprocate left and right, they will also drive the multiple groups of fixed columns 117 to move. When the fixed columns 117 move and contact the multiple groups of protrusions 114 set inside the screening bin 8, and because the connecting plate 116 and the screen 109 are connected by an up and down sliding snap connection, the two groups of screens 109 will also shake up and down while reciprocating left and right, which can further fully screen the crushed slag. When the folding rod 108 reciprocates left and right, it will also drive the connecting rod 110 to move. The movement of the connecting rod 110 can drive the first piston rod 111 to slide inside the first piston cylinder 112, so that the two groups of screens 109 can screen and the two groups of crushing leaves 115 can suck the dust generated after the slag is crushed. The extracted dust will be transported to the inside of the collecting bag 113 for collection, which can not only prevent the dust from polluting the external environment, but also prevent the accumulation of dust from damaging the device.
[0066] When the two groups of crushing leaves 115 crush the slag, and the two groups of screens 109 screen the crushed slag, the screened slag will fall onto the surface of the grinding plate 214 inside the grinding bin 9. At this time, when the crushing shaft 118 rotates, it will drive the first belt 119 to rotate through the pulley 104. The rotation of the first belt 119 will drive the transmission pulley 204 to rotate. The rotation of the transmission pulley 204 can drive the transmission shaft 201 to rotate. The rotation of the transmission shaft 201 will drive the incomplete gear 202 to rotate. Since the teeth on the surface of the incomplete gear 202 are not complete, and one end of the rack 203 is also provided with an extrusion spring, it can mesh with the transmission to drive the rack 203 to reciprocate back and forth, and the rack 203 moves. The movable frame 206 can be driven to move, and the movement of the movable frame 206 can drive the wedge plate 207 to move. When the wedge plate 207 moves, it will push the push rod 209 to reciprocate left and right inside the grinding chamber 9 through the inclined surface. The reciprocating movement of the push rod 209 can drive the through plate 210 to move. When the through plate 210 moves, it will drive multiple groups of grinding wheels 212 to reciprocate on the surface of the grinding plate 214. Since the grinding wheel 212 and the grinding plate 214 are made of materials with high friction, the grinding wheel 212 can rotate when it moves on the surface of the grinding plate 214. After the slag falls on the surface of the grinding plate 214, the grinding wheel 212 can be rolled and squeezed, and the slag can be initially ground, which is convenient for subsequent use.
[0067] At the same time, when the through plate 210 moves, it can also drive the multiple groups of rubbing rods 211 to move on the surface of the grinding plate 214. At this time, the slag dropped between the multiple groups of rubbing rods 211 will be swept to the through holes opened on the surface of the through plate 210, so as to be roll-ground by the grinding wheel 212. After the grinding wheel 212 rolls and grinds the slag, it will fall into the inside of the grinding cylinder 218 through the grinding plate 214. At this time, the rotation of the transmission shaft 201 will drive the fixed plate 213 to rotate inside the grinding cylinder 218, and when the fixed plate 213 rotates, it will drive the multiple groups of grinding rods 219 to rotate inside the grinding cylinder 218. Since the grinding rods 219 are rotatably connected to the fixed plate 213, and a plurality of through holes are opened on the surface of the grinding cylinder 218, when the grinding rods 219 move to the position where there are no through holes on the surface of the grinding cylinder 218, when the grinding rods 219 contact the grinding cylinder 218, they can also rotate themselves, thereby performing secondary grinding on the slag, and the slag can be fully ground and crushed.
[0068] After the grinding wheel 212 and the grinding rod 219 grind the slag, the ground slag will fall onto the surface of the two sets of curved rotating plates 217 below the grinding bin 9 through the surface of the grinding cylinder 218. At the same time, the reciprocating motion of the rack 203 can also drive the magnetic block 205 to move. The movement of the magnetic block 205 will magnetically drive the blocking plate 208 to slide inside the grinding bin 9. When the blocking plate 208 moves to a position away from the storage box 10, the solid waste inside the storage box 10 can fall onto the surface of the curved rotating plate 217 below the grinding bin 9. When the blocking plate 208 moves to a position close to the storage box 10, the discharge port of the storage box 10 can be opened. The plugging can improve the accuracy of the ratio between the slag powder and the solid waste. At the same time, when the solid waste and the slag powder fall onto the surface of the curved rotating plate 217, the first belt 119 drives the matching shaft 215 to rotate through the pulley. The rotation of the matching shaft 215 drives the two sets of curved rotating plates 217 to rotate relative to each other through the third gear set 216. At this time, the rotation of the two sets of curved rotating plates 217 can make the slag powder and the solid waste to be mixed for the first time. At the same time, when the surfaces of the two sets of curved rotating plates 217 are in contact, the slag powder and the solid waste can be squeezed and ground, which can avoid the slag powder from being too large in volume after the slag powder and the solid waste are mixed, and can improve the fineness of the slag powder.
[0069] After the slag powder and the solid waste are mixed and ground, they will fall onto the surface of the moving plate 306 inside the extrusion bin 11. Since the surface of the moving plate 306 is provided with through holes, the slag powder and the solid waste will fall onto the surface of the bottom plate 307 below the moving plate 306. Since there is a gap between the moving plate 306 and the bottom plate 307, when the moving frame 206 drives the moving plate 306 to move inside the grinding bin 9, the slag powder and the solid waste can be mixed again. At the same time, since the slag powder and the solid waste move in the gap between the moving plate 306 and the bottom plate 307, the slag powder and the solid waste can be kneaded and ground again. When the slag powder and the solid waste fall from the surface of the bottom plate 307 into the mixing bin 7, the second motor 30 is started at this time. The rotation of the second belt 302 is driven by the pulley to rotate, thereby driving the multiple groups of auger rods 303 to rotate inside the mixing bin 7, so as to finally mix and stir the slag powder and the solid waste. At the same time, when the movable frame 206 reciprocates, it will also drive the convex plate 304 to move. The convex plate 304 will push the second piston rod 308 to slide inside the second piston cylinder 309, so that part of the raw materials inside the storage box 305 can be transported to the surface of the arc plate 311 through the connecting hose 310, and then flow to the surface of the moving plate 306 through the arc plate 311, so that the slag powder and the solid waste can be mixed and stirred with the raw materials or the stimulant in advance, and the phenomenon of uneven mixing of multiple materials can be avoided when the auger rod 303 stirs the cement without clinker.
