Description

Technical Field

[0001] This utility model relates to the field of mine ecological restoration technology, and in particular to a processing equipment for producing kaolin from coal gangue. Background Technology

[0002] The equipment for producing kaolin from coal gangue uses an agitator to drive the grinding media to rotate at high speed inside the grinding cylinder. This causes strong impact, friction, and shearing between the grinding media and the material, thereby crushing and grinding the coal gangue to achieve the particle size requirements for kaolin. During the mixing process, the material is evenly mixed and dispersed, which is beneficial for subsequent processing.

[0003] The significant differences in particle size and density between coal gangue and other additives in processing equipment can lead to stratification or uneven mixing during the mixing process. Denser particles tend to sink, while lighter additives tend to accumulate at the top or edges, affecting the quality stability of the final kaolin product. Existing technologies employ ribbon impellers or turbine impellers. Ribbon impellers provide strong axial conveying capacity, allowing materials to circulate within the mixing tank and reducing material accumulation and stratification. Turbine impellers offer excellent shearing and dispersing capabilities, effectively crushing and mixing materials. However, in actual use, the raw materials crushed by ribbon impellers can vary in size, resulting in uneven mixing and reduced product quality. Utility Model Content

Supports 4 are fixedly connected to the tops of both mixing tanks 3, and motors 5 are fixedly connected to the tops of both supports 4. The output ends of both motors 5 pass through the supports 4, and rotating rods 6 are fixedly connected to the output ends of both motors 5. The motors 5 start and drive the rotating rods 6 to rotate. Two stirring blades 7 are fixedly connected to the outer walls of both rotating rods 6. The rotation of the rotating rods 6 drives the stirring blades 7 to rotate, thus stirring the internal raw materials to obtain a second-grade nutrient soil matrix. A support frame 8 is fixedly connected to the top right side of the top of the support frame 1. A feed pipe 9 is fixedly connected to the top right side of the inner side of the support frame 1 for the raw material to enter. A groove 10 is opened on the top of the support frame 8. A filter screen 11 is fixedly connected inside the groove 10. The raw material is put into the groove 10. The filter screen 11 can filter out larger impurities. Then the filtered raw material enters the feed pipe 9. The bottom of the top mixing tank 3 is connected to the discharge pipe 12. A valve 13 is fixedly connected to the outer wall of the discharge pipe 12. The mixed raw material enters the discharge pipe 12 and flows into the bottom mixing tank 3 through the valve 13. Then, high molecular water-retaining resin, ion-state effective potassium-releasing bacteria and heavy metal passivating bacteria are added to the bottom mixing tank 3. After mixing, the No. 1 nutrient soil matrix is ​​obtained. A picking mechanism 2 is set on the outer wall of the bottom mixing tank 3. The picking mechanism 2 is used to pick up the bottom mixing tank 3.

[0032] Specifically, the inner middle and bottom of the fixed frame 1 are connected to the mixing tank 3. The large-particle soil substrate in the top mixing tank 3 is fully integrated with soil aggregation promoting bacteria, ion-available potassium releasing bacteria, heavy metal inactivating bacteria, and organic fertilizer made from fermented cow or sheep manure. Each mixing tank 3 has a support 4 on top, and a motor 5 is fixed on the support 4. After the motor 5 is started, its output end drives the rotating rod 6 to rotate, and the two stirring blades 7 on the outer wall of the rotating rod 6 also rotate, fully mixing the raw materials in the top mixing tank 3, and finally obtaining the second nutrient soil substrate. The top right side of the fixed frame 1 is equipped with a support frame 8, and the inner top right end is connected to Next, a filter screen 11 is installed in the groove 10 at the top of the feed pipe 9 and the support frame 8. When we pour the raw material into the groove 10, the filter screen 11 will intercept larger impurities, ensuring that the pure raw material enters the feed pipe 9 and flows into the top mixing tank 3. The discharge pipe 12 at the bottom of the top mixing tank 3 is connected to the valve 13. After the mixing is completed, the valve 13 is opened, and the No. 2 nutrient soil substrate will flow into the bottom mixing tank 3 along the discharge pipe 12. Then, high molecular weight water-retaining resin, ion-state effective potassium-releasing bacteria and heavy metal passivating bacteria are added to the bottom mixing tank 3. After being stirred again by the stirring blades 7 in the bottom mixing tank 3, the No. 1 nutrient soil substrate is finally formed.

[0033] Reference Figure 5 The taking mechanism 2 includes two sliding plates 201, which are fixedly connected to the left and right sides of the bottom mixing tank 3. The bottom inner side of the fixing frame 1 is provided with a sliding groove 202 at both the left and right ends. The sliding plates 201 can slide back and forth inside the sliding groove 202. A hinge 203 is fixedly connected to the front end of the left bottom of the fixing frame 1. A baffle 204 is fixedly connected to the front end of the right end of the hinge 203. The baffle 204 is opened and closed by the hinge 203. A buckle 205 is fixedly connected to the front end of the right side of the fixing frame 1. A pipe clamp 206 is fixedly connected to the right side of the baffle 204. The buckle 205 fastens the pipe clamp 206 and can close the baffle 204 to prevent the bottom mixing tank 3 from sliding out due to vibration.

[0034] Specifically, two sliding plates 201 are fixedly connected to the left and right sides of the bottom mixing tank 3, respectively. Correspondingly, sliding grooves 202 are provided at the bottom left and right ends of the inner side of the fixing frame 1. The sliding plates 201 can slide flexibly back and forth in the sliding grooves 202, which facilitates the installation and adjustment of the bottom mixing tank 3. A hinge 203 is installed at the front end of the bottom left side of the fixing frame 1, and a baffle 204 is connected to the front end of its right side, so that the baffle 204 can be opened and closed freely through the hinge 203. A buckle fixing device 205 is fixed at the front end of the right side of the fixing frame 1, and a pipe clamp 206 is connected to the right side of the baffle 204. When it is necessary to fix the bottom mixing tank 3, simply close the baffle 204 so that the buckle fixing device 205 locks the pipe clamp 206, which can effectively prevent the bottom mixing tank 3 from sliding out due to the vibration generated by mixing, and ensure that the entire mixing work is carried out safely and stably.

[0035] Reference Figure 1 A connecting plate 14 is fixedly connected to the middle right side of the fixed frame 1. A warning sign 15 is fixedly connected to the right side of the connecting plate 14 to remind people to pay attention to safety. A lamp holder 16 is fixedly connected to the top left side of the fixed frame 1. A lighting lamp 17 is rotatably connected to the top of the lamp holder 16 to increase the brightness of the working area. Anti-collision pads 18 are fixedly connected to the four corners of the outer wall of the fixed frame 1. All anti-collision pads 18 adopt a smooth design to prevent injury.

[0036] Specifically, a warning sign 15 is securely connected to the connecting plate 14 on the middle right side of the fixed frame 1, constantly reminding people around to pay attention to safety. A lighting lamp 17 is rotatably connected to the top of the lamp holder 16 on the top left of the fixed frame 1. The angle of the light can be adjusted according to work needs to effectively improve the brightness of the work area and ensure that the working environment is clearly visible. The four corners of the outer wall of the fixed frame 1 are equipped with rounded anti-collision pads 18, which can greatly avoid injury caused by accidental collisions.

[0037] Reference Figure 2 and Figure 5 Support columns 19 are fixedly connected to the four corners of the bottom of the fixed frame 1. Anti-slip sleeves 20 are fixedly connected to the bottom of the multiple support columns 19 to prevent the device from moving when it is started. The two sliding plates 201 are symmetrically designed. The outer diameter of the two sliding plates 201 is smaller than the inner diameter of the slide groove 202. The sliding plates 201 can slide in the slide groove 202. The two mixing tanks 3 are equal in size. The bottom of the two mixing tanks 3 is chamfered.

[0038] Specifically, support columns 19 are connected to the four corners of the bottom of the fixed frame 1, and anti-slip sleeves 20 are installed at the bottom of each support column 19, which effectively increases the friction with the ground and prevents the device from shifting due to vibration when it starts mixing. The two sliding plates 201 installed to cooperate with the bottom mixing tank 3 adopt a symmetrical design, and their outer diameter is smaller than the inner diameter of the chute 202 to ensure smooth sliding. The bottoms of the two equal-sized mixing tanks 3 are both chamfered to facilitate material discharge.

[0039] Working principle: Prepare the raw materials, including large-particle soil matrix, soil aggregation promoting bacteria, ion-based effective potassium releasing bacteria, heavy metal inactivating bacteria, and organic fertilizer made from fermented cow or sheep manure. Pour these raw materials into the groove 10 of the support frame 8 on the right side of the top of the fixed frame 1. The filter screen 11 in the groove 10 will intercept larger impurities, allowing the pure raw materials to enter the top mixing tank 3 through the feed pipe 9. In the top mixing tank 3, the motor 5 is started, and its output end drives the rotating rod 6 to rotate, which in turn drives the stirring blades 7 on the outer wall of the rotating rod 6 to rotate, fully mixing the raw materials in the tank 3, and finally obtaining the No. 2 nutrient soil matrix. After the mixing is completed, open the valve 13 on the discharge pipe 12 at the bottom of the top mixing tank 3, and the No. 2 nutrient soil matrix flows into the bottom mixing tank 3. Add high-molecular water-retaining resin, ion-based effective potassium releasing bacteria, and heavy metal inactivating bacteria into the bottom mixing tank 3. The stirring blades 7 in the bottom mixing tank 3 mix these materials again, and finally form the No. 1 nutrient soil matrix.

[0040] Furthermore, the sliding plate 201 can slide flexibly back and forth within the chute 202, greatly facilitating the installation of the bottom mixing tank 3. The operator pushes the mixing tank 3 along the chute 202 into the predetermined position within the fixing frame 1. It can also be easily operated during subsequent equipment maintenance, repair, or adjustment of the position of the mixing tank 3 due to production needs. Once the bottom mixing tank 3 is installed in place, the operator only needs to close the baffle 204 so that the buckle fixing device 205 accurately engages with the pipe clamp 206, thus forming a stable locking structure. This effectively prevents the bottom mixing tank 3 from shifting due to vibration, ensuring that the entire mixing operation continues in a safe and stable environment.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
