Description

Technical Field

[0001] This invention relates to the field of mortar preparation technology, specifically to a mixing device for high-copper tailings mortar. Background Technology

[0002] High-copper tailings slurry, also known as high-copper tailings slurry, is an industrial waste primarily originating from the copper mine beneficiation process. During copper ore beneficiation, after most of the valuable minerals are extracted, the remaining slag is called tailings. These tailings may still contain a certain amount of valuable minerals. Over a long period of sedimentation and solidification, the tailings accumulated in tailings ponds form a cement-like substance. This substance can be used to manufacture building materials such as cement and concrete. Because this building material contains a certain amount of copper minerals, it is called high-copper tailings slurry. Using high-copper tailings slurry as a building material can effectively reduce construction waste emissions, lower environmental pollution, conserve resources, and reduce the production costs of building materials.

[0003] In the production of high-copper tailings mortar, various raw materials first need to be mixed together in a certain proportion. These raw materials typically include tailings, cement, water, and other additives. Depending on different production requirements, the proportions of various raw materials need to be precisely controlled to ensure that the performance and quality of the final product meet the requirements. After mixing the various raw materials together, they need to be stirred and mixed. The purpose of stirring is to ensure that the various raw materials are fully and evenly mixed to ensure the performance and quality of the product. During the stirring process, the stirring time and speed need to be controlled to avoid over-stirring or under-stirring. However, in the actual mixing process, high-copper tailings mortar often has a substandard moisture content in the raw materials. This is mainly due to improper control of the ratio between the added water and the raw materials, resulting in excessively high or low humidity in the high-copper tailings mortar. Substandard moisture content will affect the uniformity of mixing and the fluidity of the mortar, and will also affect the performance and use effect of the mortar, leading to problems such as caking and deterioration. This will have an adverse effect on the mixing effect of high-copper tailings mortar. Therefore, we propose a mixing device for high-copper tailings mortar. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention utilizes a sampling pipe to sample mortar within the mixing mechanism, collects the sampled mortar under the action of a sampling sleeve, and simultaneously detects the weight of the sampled mortar under the action of a weight sensing element. A heating wire is used to dry the mortar. The moisture content of the mortar can be effectively measured based on the difference in the detection results. Simultaneously, a worm gear reducer controls the drive shaft to rotate in a directional manner, driving the sampling sleeve to rotate synchronously under the action of a guide mechanism, sliding sleeve, and connecting parts. This allows for the replacement of multiple sampling sleeves, achieving the purpose of multiple sampling and testing of the mortar within the mixing mechanism, facilitating effective handling of the mortar during the mixing process by the operators.

[0019] 2. This invention utilizes trapezoidal and annular grooves to change the position of the sampling sleeve. Under the action of meshing gears, the meshing gears drive the sampling sleeve to rotate through the rotating shaft and connecting shaft. Simultaneously, under the action of the guide sleeve and collecting sleeve, the dried mortar inside the sampling sleeve is collected. Furthermore, a high-pressure water gun can be used to clean the inner wall of the sampling sleeve, thereby enabling automated sampling and testing of mortar in the mixing mechanism, thus improving the efficiency and accuracy of mortar testing.

[0020] 3. This invention utilizes a stirring rod to drive the fixed frame to rotate, so that the extended frame and the annular frame on the fixed frame rotate synchronously. Under the action of the annular gear rack, the drive gear drives the transmission shaft to rotate. Utilizing the transmission action of the chain wheel and chain, the mixing shaft can rotate, and through the connecting sleeve on it, it can drive the flexible rod to mix the mortar in the mixing mechanism. At the same time, under the action of the annular electromagnetic component and magnetic panel, the deformation degree of the flexible rod can be controlled, which can fully change the fluidity of the mortar, thereby improving the mixing quality and efficiency.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see the appendix Figure 1-15 This invention provides a technical solution: a mixing device for high-copper tailings mortar. This invention addresses the technical problems raised in the background art by making corresponding improvements, including a mixing mechanism 1. Further, the mixing mechanism 1 in this invention includes a main body (containing an inlet and an outlet), a ladder, and a support, as detailed in the attached figure. Figure 1 As shown, a servo motor 2 is fixedly installed on one side of the mixing mechanism 1, and a stirring rod 3 is fixedly connected to the output end of the servo motor 2. The end of the stirring rod 3 passes through the side wall of the mixing mechanism 1 and is rotatably connected to the inner wall of the other side of the mixing mechanism 1. Further, a limiting sleeve 9 is fixedly installed on both sides of the mixing mechanism 1, and the stirring rod 3 is limited to rotate inside the limiting sleeve 9. A detection frame 4 is fixedly installed on the outer wall of one side of the mixing mechanism 1, and a sampling pipe 5 is fixedly installed on one side of the mixing mechanism 1. One end of the sampling pipe 5 passes through the outer wall of the detection frame 4 and extends into the interior. Further, a solenoid valve 51 is installed on the sampling pipe 5, and the solenoid valve 51 is controlled by the central control program. A worm gear reducer 6 is fixedly installed at the bottom of the detection frame 4, and the output end of the worm gear reducer 6 penetrates through the outer wall of the bottom of the detection frame 4 and extends into the interior. A drive shaft 61 is fixedly installed at one end of the worm gear reducer 6 located inside the detection frame 4. Multiple guide mechanisms 62 are fixedly installed on the outside of the drive shaft 61. It should be noted that the guide mechanism 62 in this invention includes two fixed plates fixedly installed on the outside of the drive shaft 61. Further, one fixed plate is fixedly installed on the top of the drive shaft 61, and the other fixed plate is installed near the bottom of the drive shaft 61. A guide shaft connects the two, as detailed below. Figure 5As shown, each guide mechanism 62 is slidably sleeved with a sliding sleeve 63 on its outer side. A return spring 67 is sleeved on the outer side of the guide mechanism 62 and positioned above the sliding sleeve 63, allowing the sliding sleeve 63 to slide at its upper limit on the guide shaft. A sampling sleeve 64 is located on the side of the sliding sleeve 63 away from the drive shaft 61. A connecting member 65 is provided between the sampling sleeve 64 and the sliding sleeve 63. As a further limitation of the invention, the connecting member 65 includes a connecting shaft 651 fixedly installed on the outer wall of the sampling sleeve 64. A rotating shaft 652 is also fixedly installed at the end of the connecting shaft 651 away from the sampling sleeve 64. The end of the rotating shaft 652 is located inside the sliding sleeve 63 and rotatably connected to its inner wall. A meshing gear 653 is fixedly installed on the outside of the moving shaft 652. A torsion spring 654 is connected between the meshing gear 653 and the end of the sliding sleeve 63. One of the sampling sleeves 64 is located below the end of the sampling pipe 5 and on the discharge trajectory of the sampling pipe 5. A weight sensing element 66 is fixedly installed on the inner wall of the detection frame 4 and is located below the end of the sampling pipe 5. Multiple heating wires 41 are installed on the inner wall of the detection frame 4. Multiple meshing tooth rows 42 are fixedly installed on the top inner wall of the detection frame 4, and each meshing tooth row 42 is located on the movement trajectory of the meshing gear 653. To further explain, there are two meshing tooth rows 42, and the length of the first meshing tooth row 42 is greater than the length of the second meshing tooth row 42.

[0039] It should be noted that the present invention uses a sampling method to detect the moisture content of the high copper tailings slurry in the mixing mechanism 1. The weight sensing element 66 is used to detect the weight of the high copper tailings slurry at the initial stage (i.e., immediately after sampling). Subsequently, the heating wire 41 is activated to dry the slurry. The dried slurry is then detected again by the weight sensing element 66. The moisture content of the slurry can be obtained based on the two measurement results. Furthermore, the relative humidity of the slurry can be measured by means of the capacitance volume effect. Since this method of relative humidity measurement is a conventional technology that uses the characteristic that the capacitance value of a capacitor sensor changes with the relative humidity of the environment, the capacitance of the humidity-sensitive capacitor is small when the relative humidity is low; when the relative humidity increases, the capacitance of the humidity-sensitive capacitor also increases. Therefore, by measuring the change in capacitance, the relative humidity in the environment can be calculated. Therefore, the present invention does not describe it in detail.

[0040] Furthermore, in the process of detecting the moisture content of high copper tailings slurry, the preferred detection time periods are the early, middle, and late stages of mixing. This invention further improves upon this by providing an annular groove 43 and a trapezoidal groove 44 connected to the annular groove 43 on the inner wall of the detection frame 4. The sampling pipe 5 is located above the vertical surface of the trapezoidal groove 44, and the weight sensing element 66 is located below the vertical surface of the trapezoidal groove 44 (as shown in the attached diagram). Figure 8As shown), each sampling sleeve 64 has a sliding shaft 641 installed on its outer wall, which is limited and slides within the annular groove 43 and the trapezoidal groove 44. The sliding shaft 641 is rotatably connected to the outer wall of the sampling sleeve 64. A guide sleeve 7 is fixedly installed on the bottom inner wall of the detection frame 4, and the guide sleeve 7 is located below one of the meshing tooth rows 42. A collection sleeve 71 is slidably connected to the inner wall of the guide sleeve 7. The collection sleeve 71 penetrates the bottom inner wall of the detection frame 4 and extends to the outside. The collection sleeve 71 is fixedly connected to the bottom of the detection frame 4 by bolts. A high-pressure water gun 8 is installed inside the detection frame 4, and the high-pressure water gun 8 is located on the movement trajectory of the sampling sleeve 64.

[0041] Specifically, in conjunction with the appendix Figure 1-8 As shown, during the mixing process of the mixing mechanism 1, the material inside the mixing mechanism 1 enters the detection frame 4 through the sampling pipe 5 by controlling the solenoid valve 51. Under the action of the sampling pipe 5, the material flows to the sampling sleeve 64 located below the sampling pipe 5 (and on the discharge trajectory of the sampling pipe 5). Then, the weight sensing element 66 detects the weight of the sampling sleeve 64. After the detection data is constant, multiple heating wires 41 are activated to raise the temperature inside the detection frame 4, and the high copper tailings slurry is dried. The weight of the dried high copper tailings slurry is reduced. The weight of the high copper tailings slurry is detected by the weight sensing element 66, and the moisture content of the slurry can be obtained from the two measurement results. After the test is completed, if the measurement result is normal, the mixing mechanism 1 continues to work. If the measurement result is abnormal, the operator needs to add the corresponding material into the mixing mechanism 1.

[0042] After sampling and testing are completed, the worm gear reducer 6 is started, and its output end controls the drive shaft 61 to rotate. This causes multiple guide mechanisms 62 on the drive shaft 61 to rotate synchronously, and consequently, the sliding sleeve 63, which is slidably connected to the guide mechanisms 62, rotates synchronously with them. The sampling sleeve 64 rotates with the sliding sleeve 63 under the action of the connecting shaft 651 and the rotating shaft 652. Further, the rotating shaft 652 in this invention is a damping shaft. It should be noted that the preferred number of guide mechanisms 62 in this invention is N (N≥4). (See attached diagram.) Figure 8As shown, the sampling sleeve 64 located below the sampling pipe 5 has its sliding shaft 641 located at the straight surface of the trapezoidal groove 44. The sliding shafts 641 corresponding to the remaining sampling sleeves 64 are located in the annular groove 43. When the worm gear reducer 6 starts, multiple sampling sleeves 64 rotate with the rotation of the drive shaft 61. That is, the sampling sleeve 64 initially located below the sampling pipe 5 will enter the annular groove 43 under the action of the trapezoidal groove 44. At this time, the height of the sampling sleeve 64 changes, and correspondingly, one of the sampling sleeves 64 adjacent to it will rotate. Under the action of the trapezoidal groove 44, it enters below the sampling pipe 5 (and is located on the discharge trajectory of the sampling pipe 5—that is, the position before the sampling sleeve 64 rotates). When the sliding shaft 641 is located in the annular groove 43 and the sampling sleeve 64 rotates with the drive shaft 61, the meshing gear 653 on the rotating shaft 652 will mesh with the meshing gear row 42. That is, the meshing gear 653 is driven by the meshing to rotate the rotating shaft 652 in a directional manner within the sliding sleeve 63. At the same time, the connecting shaft 651 connected to the rotating shaft 652 and the sampling sleeve 64 rotate synchronously with it. Figure 3-5 and attached Figure 7 As shown, one of the sampling sleeves 64 rotates 90° under the action of the meshing gear 653 and the meshing gear rack 42 (when it rotates to 90°, the worm gear reducer 6 stops starting). During the rotation from 0° to 90°, the sampling sleeve 64 is located in the feeding area of ​​the guide sleeve 7, and the dried mortar in the sampling sleeve 64 will fall into the collecting sleeve 71 for collection under the action of gravity. At the same time, the other sampling sleeve 64 adjacent to the sampling sleeve 64 (located directly above the guide sleeve 7) (the other sampling sleeve 64 away from the discharge trajectory of the sampling pipe 5) is tilted and located on the spray trajectory of the high-pressure water gun 8. To further explain, the meshing gear 653 on the sampling sleeve 64 located directly above the guide sleeve 7 is still in a meshing state with the meshing gear rack 42. Therefore, when the worm gear reducer 6 starts, the meshing gear... 653 will still rotate under the meshing action of the meshing gear row 42, that is, it will continue to rotate after rotating 90°. When it moves to the spray trajectory of the high-pressure water gun 8, the sampling sleeve 64 is set at an angle. The high-pressure water gun 8 cleans the sampling sleeve 64. To further explain, a water tank needs to be set inside the detection frame 4 to collect and guide the water flow from the high-pressure water gun 8. Since the water tank is an existing technology structure and a common knowledge mechanism, this invention does not describe it in detail. After cleaning, the sampling sleeve 64 is dried under the heating condition of the heating wire 41. Then, when the worm gear reducer 6 continues to rotate, the meshing gear 653 corresponding to the cleaned sampling sleeve 64 will mesh with another meshing gear row 42. The sampling sleeve 64 continues to rotate, and its opening returns to the initial position (i.e., the opening is upward).

[0043] To further explain, if the moisture content of the high-copper tailings mortar does not meet the standard before sampling and testing, mortar clumping is likely to occur during the mixing process. Although the mortar preparation quality is improved after adding materials, the previously clumped mortar is still prone to clumping during subsequent mixing. Therefore, this invention makes corresponding improvements. A fixing frame 31 is symmetrically fixedly installed on the outer wall of the stirring rod 3. Multiple extension frames 32 are fixedly installed on the outer side of the fixing frame 31. An annular frame 33 is fixedly connected to the side of the fixing frame 31 close to the limiting sleeve 9, and the annular frame 33 is rotatably connected to the outer wall of the limiting sleeve 9. An annular toothed row 91 is fixedly installed on the outer wall of the limiting sleeve 9. That is, the annular frame 33 is used to adjust the annular toothed row. The toothed rack 91 is protected to prevent it from being exposed to the mortar environment. Multiple drive gears 331 are installed inside the annular frame 33, and all drive gears 331 are meshed with the annular toothed rack 91. Each drive gear 331 has a transmission shaft 34 rotatably connected to the inner wall of the annular frame 33. The end of the transmission shaft 34 passes through the inner walls of the annular frame 33 and the extension frame 32, and is rotatably connected to the inner wall of the extension frame 32. Therefore, when the servo motor 2 controls the stirring rod 3 to rotate, the fixed frame 31 on the outside of the stirring rod 3 drives the extension frame 32 and the annular frame 33 to rotate. Simultaneously, the annular frame 33 rotates at its limit on the outer wall of the limiting sleeve 9. The drive gear 331 inside the annular frame 33 is engaged with the annular gear rack 91. As the annular frame 33 rotates with the fixed frame 31, the drive gear 331 inside rotates due to the meshing action of the annular gear rack 91, thereby driving the transmission shaft 34 to rotate. Multiple extension shafts 35 are rotatably connected to the inner wall of the extension frame 32. The ends of the extension shafts 35 penetrate the inner wall of the extension frame 32 and extend to the outside. Chain wheels 36 are installed on the outer sides of the multiple extension shafts 35 and the transmission shaft 34, and the multiple chain wheels 36 are connected by chains. A mixing shaft 351 is fixedly connected between the extension shafts 35, and a connecting... The sleeve 352 has an annular electromagnetic component 353 fixedly installed inside. A pair of magnetic panels 354 are slidably connected inside the sleeve 352. The pair of magnetic panels 354 are distributed on both sides of the annular electromagnetic component 353. When the annular electromagnetic component 353 is energized, it generates a repulsive force on the magnetic panels 354. A fixed shaft 355 is fixedly installed on the side of the magnetic panel 354 away from the annular electromagnetic component 353. The end of the fixed shaft 355 passes through the sleeve 352 and extends to the outside. A flexible rod 356 is connected between two adjacent fixed shafts 355. A buffer spring 357 is connected between the magnetic panel 354 and the inner wall of the sleeve 352. The buffer spring 357 is sleeved on the outside of the fixed shaft 355.

[0044] Specifically, in conjunction with the appendix Figure 2 and attached Figure 9-15 As shown, the servo motor 2 starts, and its output drives the stirring rod 3 to rotate (the stirring rod 3 rotates within the limiting sleeve 9). During the rotation of the stirring rod 3, the fixed frame 31 on it drives the extension frame 32 and the annular frame 33 to rotate synchronously. Since the annular gear rack 91 is fixedly installed on the outer wall of the limiting sleeve 9, the drive gear 331 inside the annular frame 33 will rotate due to the meshing action of the annular gear rack 91. At this time, the drive gear 331 will drive the transmission shaft 34 to rotate. Thus, under the transmission action of the chain wheel 36 and the chain, the transmission shaft 34 drives the extension shaft 35 to rotate, so that the extension shaft 35 drives the mixing shaft 351 to rotate. That is, when the stirring rod 3 rotates, the multiple mixing shafts 351 on it will rotate around their own center line as the axis to improve the mixing efficiency and quality. At the same time, when the mixing shaft 351 rotates, the connecting sleeve 352 on it will... The fixed shaft 355 drives the flexible rod 356 to rotate. Since the flexible rod 356 and the stirring blades on the stirring rod 3 have different shapes, the fluid flowability can be altered to improve mixing quality and efficiency. After stirring for a certain time, the annular electromagnetic component 353 can be energized, causing it to generate a repulsive force on the magnetic panel 354. This causes the magnetic panel 354 to drive the fixed shaft 355 in a directional motion. Because both ends of the flexible rod 356 are connected to the ends of the fixed shaft 355, the flexible rod 356 can deform when the fixed shaft 355 is displaced, thus changing its shape and altering the mortar fluid flowability. This effectively stirs agglomerated mortar. Furthermore, the degree of deformation of the flexible rod 356 is controlled by the current supplied to the annular electromagnetic component 353, thereby effectively controlling the mortar flowability by changing the degree of deformation of the flexible rod 356.
