Description

Technical Field

[0001] The invention relates to the technical field of cement material processing, in particular to cement-stabilized coal gangue mixture processing equipment and a preparation method. Background Art

[0002] Cement-stabilized gangue mixture is a material made by mixing cement with raw materials such as gangue in a certain proportion. Gangue is solid waste generated in the coal mining process. Its utilization can not only reduce environmental pollution, but also effectively utilize resources. Cement-stabilized gangue is usually used for the base or subbase of roads, which can improve the bearing capacity and stability of roads. In the production process of cement-stabilized gangue mixture, cement and gangue with suitable particle size need to be evenly mixed through mixing and processing equipment. When using existing processing equipment, it is usually directly mixed with cement and gangue using a stirring structure. Since the mixture is only stirred in the horizontal direction, the mixing speed is relatively slow. When the cement and gangue particles are transported to the stirring structure, the cement and gangue are easy to accumulate separately. It takes a long time to mix the separately accumulated cement and gangue particles, and the processing time is relatively long. Summary of the invention

When the transmission belt drives the fixed rod and the partition to move, so that the fixed rod and the partition pass the bottom of one feeding frame, the cement material in one feeding frame will first fall on the transmission belt and fill between two adjacent fixed rods. Then, when passing the bottom of another feeding frame, since the bottom height of the other feeding frame is higher than the bottom height of the one feeding frame, the coal gangue material in the other feeding frame will fall on the top of the cement material, thereby spreading the cement and coal gangue materials between the two adjacent fixed rods. The thickness of the cement and coal gangue materials spread on the transmission belt is relatively thin, so that when the mixed material is transported to the mixing drum, it is convenient for the cement and coal gangue to be mixed quickly, and the stirring mechanism can be rotated and moved upward, so that the mixed material is gradually spread to avoid the material being accumulated in only one place, which is beneficial to the subsequent mixing.

[0063] Embodiment 1

[0064] like Figure 4-8 As shown, in this embodiment, the stirring mechanism 120 includes two stirring plates 121, a plurality of arc-shaped rods 122, a plurality of arc-shaped plates 123, and a connecting ring 125;

[0065] The two stirring plates 121 are both arranged on the two round rods 141. The opposite sides of the two stirring plates 121 are convex. The top surface of the stirring plates 121 is provided with a strip groove 1211 which is slidably connected to the side surfaces of the adjacent round rods 141. The plurality of arc rods 122 are all fixedly connected to the side surfaces of the adjacent stirring plates 121. The plurality of arc rods 122 are divided into two groups. The two groups of arc rods 122 are respectively fixedly connected to the opposite sides of the two stirring plates 121. The arc rods 122 on the two stirring plates 121 have opposite bending directions. The plurality of arc plates 123 are all fixedly connected to the opposite sides of the two stirring plates 121. The connecting ring 125 is fixedly connected to the middle of the opposite sides of the two stirring plates 121. The connecting ring 125 can connect the two stirring plates 121.

[0066] The bottom surface of the connecting block 140 is fixedly connected to a connecting rod 144 that is rotatably connected to the inner side surface of the connecting disk 130. The inner sides of the two stirring disks 121 are screwed together to connect an adjusting screw 170 that is rotatably connected to the bottom surface of the rotating block 143. The adjusting screw 170 passes through the connecting ring 125 and the inside of the connecting rod 144. The two stirring disks 121 are both provided with a multi-stage telescopic rod 160 on the opposite sides. The top of the multi-stage telescopic rod 160 at the top is fixedly connected to the bottom surface of the rotating block 143, and the multi-stage telescopic rod 160 at the bottom passes through the inside of the connecting block 140 and is fixedly connected to the inner side surface of the connecting rod 144. The multi-stage telescopic rod 160 has three sleeves. The three sleeves are slidably connected in sequence, and the convex surfaces of the stirring plate 121 are fixedly connected to the ends of the adjacent multi-stage telescopic rods 160. When the stirring plate 121 moves up and down, the three-section sleeves can be extended or contracted, and the connecting rod 144 can support the outer sleeve of the bottom multi-stage telescopic rod 160. The side of the adjusting screw rod 170 is rotatably connected to the bottom of the inner side of the multi-stage telescopic rod 160. The adjusting screw rod 170 is located inside the sleeve of the multi-stage telescopic rod 160. In this way, when the stirring plate 121 moves, the adjusting screw rod 170 can be blocked by the multi-stage telescopic rod 160, and the bottom multi-stage telescopic rod 160 can support the bottom of the adjusting screw rod 170.

[0067] In a specific implementation, when the round rod 141 rotates, the round rod 141 can drive the stirring plate 121 to rotate through the strip groove 1211, and the stirring plate 121 can drive the arc rod 122 and the arc plate 123 to rotate, so that the cement and coal gangue mixture is stirred through the arc rod 122 and the arc plate 123. During stirring, the adjusting screw rod 170 can be rotated relative to the stirring plate 121. At this time, the stirring plate 121 will move upward or downward along the adjusting screw rod 170, so that the stirring plate 121 moves up and down along the round rod 141, and the stirring frame 142 can pass through the strip groove 1211, so that the mixture can be stirred up and down through the stirring plate 121, and when the stirring plate 121 moves up and down, the arc rod 122 on the convex surface of the stirring plate 121 can be used to push away the stirring plate 121 in the forward direction. The mixed material is stirred so that the stirring disk 121 can move downward or upward smoothly. When the arc rod 122 rotates and moves upward, since the arc plate 123 and the top arc rod 122 are bent in opposite directions, the arc plate 123 can gather part of the mixed material between the two stirring disks 121. As the stirring disk 121 moves upward, the stirring disk 121 can bring the material to the top of the mixing drum 110. When the stirring disk 121 rotates in the opposite direction to make the bottom arc rod 122 push away the mixed material at the bottom of the stirring disk 121, since the arc plate 123 and the bottom arc rod 122 have the same bending direction, the mixed material between the two stirring disks 121 can be thrown out through the arc plate 123, which is beneficial to the upper and lower mixing of the materials, improves the mixing treatment effect, and reduces the treatment time.

[0068] like Figure 6 As shown, in this embodiment, the driving mechanism 150 includes a connecting box 151, a driving motor 152, a transmission shaft 153, two connecting gears 157, two connecting gears 2 158, a driving motor 2 154, a transmission shaft 2 155, a linkage rod 156, and two connecting gears 3 159;

[0069] The top surface of the connecting box 151 is fixedly connected to the bottom surface of the mixing barrel 110, the side surface of the connecting disk 130 is rotatably connected to the inner side surface of the top of the connecting box 151, the connecting disk 130 can rotate at the top of the connecting box 151, the inner side surface of the connecting box 151 is fixedly connected with a support seat 1511, the driving motor 152 is arranged on the inner bottom surface of the connecting box 151, the bottom end of the transmission shaft 153 is transmission-connected to the output end of the driving motor 152, two connecting gears 157 are arranged inside the connecting box 151, the two connecting gears 157 are meshed for transmission, one connecting gear 157 is fixedly sleeved on the side surface of the transmission shaft 153, and the other connecting gear 157 is fixedly sleeved on the bottom of the side surface of the connecting rod 144, two connecting gears 2 158 are arranged inside the connecting box 151, the two connecting gears 2 158 are meshed for transmission, one connecting gear 2 158 is fixedly sleeved on the transmission shaft 153, and the other connecting gear 2 158 is fixedly sleeved on the adjusting screw 170;

[0070] The driving motor 2 154 is fixedly connected to the top surface of the support seat 1511, and the support seat 1511 can support the driving motor 2 154. The bottom end of the transmission shaft 2 155 is transmission-connected to the output end of the driving motor 2 154. A positioning plate rotatably connected to the transmission shaft 2 155 is provided on the inner side surface of the connecting box 151, and the transmission shaft 2 155 is supported by the positioning plate. The linkage rod 156 is rotationally connected to the top of the side of the transmission shaft 1 153, and the linkage rod 156 can support the top of the transmission shaft 1 153. The top of the linkage rod 156 is fixedly connected to the bottom surface of the connecting disk 130, and the two connecting gears 3 159 are respectively fixedly sleeved on the transmission shaft 2 155 and the linkage rod 156, and the two connecting gears 3 159 are meshed for transmission.

[0071] In a specific implementation, the driving motor 152 can drive the transmission shaft 153 to rotate, and the transmission shaft 153 can drive the connecting rod 144 to rotate through the connecting gear 157, and the connecting rod 144 can drive the multi-stage telescopic rod 160 and the connecting block 140 to rotate, and the connecting block 140 can drive the stirring frame 142 and the stirring plate 121 to rotate through the round rod 141, so that the stirring frame 142 and the stirring mechanism 120 can stir the mixed material, and the multi-stage telescopic rod 160 can rotate with the stirring mechanism 120. At the same time, when the transmission shaft 153 rotates, the transmission shaft 153 can drive the adjusting screw 170 to rotate through the two connecting gears 158. Since the diameter of the connecting gear 158 on the transmission shaft 153 is smaller than the diameter of the connecting gear 157 on the transmission shaft 153, when the transmission shaft 153 drives the connecting rod 144 to rotate one circle, the stirring plate 121 rotates one circle, and the adjusting screw 170 does not rotate one circle, and the stirring plate 121 rotates one circle. There is a certain speed difference between the stirring disk 121 and the adjusting screw rod 170, so that the stirring disk 121 can rotate relative to the adjusting screw rod 170, so that the stirring disk 121 can move upward along the adjusting screw rod 170, and when the driving motor 152 drives the transmission shaft 153 to rotate in the opposite direction, the stirring disk 121 moves downward along the adjusting screw rod 170, and then the stirring mechanism 120 moves up and down to stir the mixed material. During stirring, the driving motor 2 154 can drive the transmission shaft 2 155 to rotate, and the transmission shaft 2 155 can drive the linkage rod 156 to rotate through the connecting gear 3 159, and the linkage rod 156 can drive the connecting disk 130 to rotate, and the connecting disk 130 can drive the connecting block 140 to rotate, so that the stirring disk 121 rotates around the axis of the mixing drum 110 while rotating. In this way, the mixed material in the mixing drum 110 can be more comprehensively stirred through the stirring frame 142 and the stirring disk 121, which is beneficial to improving the stirring effect and reducing the stirring time.

The L-shaped plate 270 is fixedly connected to one blanking frame 260, and the side surfaces of the L-shaped plate 270 are slidably connected to the inner side surfaces of the baffle frames 250, and the side surfaces of the L-shaped plate 270 are slidably connected to the side surfaces of the other blanking frame 260. The support plate 280 is arranged on the inner top of the transmission belt 240, and the opposite surfaces of the two side plates 210 are fixedly connected to the side surfaces of the support plate 280, and the support plate 280 can support the top of the transmission belt 240.

[0077] During specific implementation, the height of the unloading frame 260 can be adjusted as needed to make the height of the bottom surface of one unloading frame 260 lower than the height of the bottom surface of the other unloading frame 260, and the cement and coal gangue can be transported to the inside of the two unloading frames 260 respectively. A transmission roller 230 is driven to rotate by a conveying motor, and the transmission roller 230 can drive the transmission belt 240 to rotate, and the transmission belt 240 can drive the fixed rod 241 and the partition 242 to move. Under the action of the torsion spring 245, the angle between the fixed shaft 244 and the partition 242 can be maintained. When the fixed rod 241 and the partition 242 move into the stop frame 250, the limit plate 261 can push the partition 242 to tilt the partition 242. When the fixed rod 241 and the partition 242 pass through the bottom of one unloading frame 260, the cement material in one unloading frame 260 will first fall on the transmission belt 240 and fill between the two adjacent fixed rods 241. At the same time, the materials are separated by the partition 242, and then the partition 2 42 will move along the bottom surface of one feeding frame 260 to the bottom of the L-shaped plate 270. When passing through the L-shaped plate 270 and moving to the bottom of another feeding frame 260, since the bottom surface height of the other feeding frame 260 is higher than the bottom surface height of the one feeding frame 260, the coal gangue material in the other feeding frame 260 will fall on the top of the cement material on the conveyor belt 240, so that the coal gangue material is spread on the top of the cement, and the cement and coal gangue are spread between two adjacent fixing rods 241. The cement and coal gangue materials spread on the transmission belt 240 are relatively thin, so when the mixed material is conveyed into the mixing drum 110, it is convenient for the cement and coal gangue to be mixed quickly. When unloading, the stirring mechanism 120 can be rotated and moved upward to throw away the mixed material falling on the stirring plate 121, and the arc rod 122 on the bottom stirring plate 121 can spread the cement and coal gangue to avoid cement or coal gangue being accumulated in only one place, which is beneficial to subsequent mixing.

[0078] A partition 242 with a smaller width can be selected as needed, so that when the partition 242 passes through the inside of the baffle frame 250, the partition 242 rotates relatively less, which is convenient for filling cement and coal gangue materials between two adjacent fixed rods 241. At the same time, the bottom of the discharge frame 260 can be set to a narrow opening with a smaller width as needed.

[0079] like Fig.10 As shown, in the present embodiment, an I-shaped frame 251 is fixedly connected to the inner side surface of the baffle frame 250 with a sliding connection to the side surface of the adjacent blanking frame 260, a power motor 252 is fixedly connected to the bottom surface of the I-shaped frame 251, a sliding groove 253 is provided on the side surface of the I-shaped frame 251, a sliding block 255 is slidingly connected to the inner side surface of the sliding groove 253 with a fixed connection to the side surface of the adjacent blanking frame 260, a positioning screw 254 is transmission-connected to the output end of the power motor 252 with a screw-engaged connection to the sliding block 255, and the side surface of the positioning screw 254 is rotatably connected to the inner side surface of the sliding groove 253, and the positioning screw 254 can support the adjacent blanking frame 260 through the sliding block 255.

[0080] During specific implementation, the power motor 252 can drive the positioning screw 254 to rotate. When the positioning screw 254 rotates, the sliding block 255 can slide up and down inside the sliding groove 253, and then the unloading frame 260 can slide up and down in the baffle frame 250. The height of the unloading frame 260 can be adjusted as needed, thereby adjusting the thickness of the cement and coal gangue spread on the transmission belt 240, and the height difference between the two unloading frames 260 can be adjusted according to the ratio.

[0081] A plurality of additional unloading frames 260 may be provided inside the retaining frame 250 so that other materials can be unloaded.

[0082] like Fig.12 As shown, a method for preparing a cement-stabilized coal gangue mixture includes a cement-stabilized coal gangue mixture processing device, which is used for mixing the mixture during the mixture preparation process. The preparation method specifically includes the preparation steps of coal gangue screening - coal gangue crushing - conveying and unloading - batching and mixing, and the specific steps are as follows:

[0083] Step (1) screening of coal gangue: using a screening device to screen the coal gangue to remove impurities in the coal gangue and coal gangue with a larger diameter;

[0084] Step (2) crushing the coal gangue: crushing the coal gangue blocks by a crushing device to crush the coal gangue into particles with suitable diameters;

[0085] Step (3) conveying and unloading: conveying cement and coal gangue materials to the unloading module 200 of the processing equipment, and conveying the materials to the mixing module 100 of the processing equipment through the unloading module 200;

[0086] Step (4) Mixing ingredients: Mix cement and coal gangue materials through the mixing module 100 to produce a cement-stabilized coal gangue mixture.

[0087] In specific implementation, when the gangue is crushed, the gangue can be screened again by a screening device to screen out gangue materials with different particle sizes. Gangue materials with different particle sizes can be added to cement to improve the natural grading of the gangue to meet the requirements of road base materials.
