Description

Technical Field

[0001] The invention relates to the technical field of coal gangue machine-made sand quality-improving devices, and in particular to a coal gangue machine-made sand quality-improving device. Background Art

[0002] Aggregates required for concrete usually account for 70% to 80% of its total volume. However, after years of mining, natural aggregate resources have been drastically reduced, and due to the low calorific value of coal gangue, it is usually discarded during coal mining. Therefore, using coal gangue as concrete aggregate to make machine-made sand can not only promote its resource utilization, but also alleviate the demand for natural aggregates.

[0003] Since the structure of gangue aggregate is looser and more porous than natural aggregate, its performance fluctuates greatly. When gangue is used as coarse aggregate in machine-made sand, the machine-made sand is easily destroyed from the interface transition zone, and the gangue aggregate is often easily crushed. In addition, the water absorption rate of machine-made sand with gangue aggregate is significantly higher than that of machine-made sand with natural aggregate. The high carbon content of gangue aggregate and its weak interface bonding with the machine-made sand matrix pose a potential threat to the durability of machine-made sand.

[0004] Among them, the study found that slurry coating can isolate moisture, thereby enhancing the performance of aggregates. Aggregate strengthening and the improved bonding between gangue aggregates and the mortar matrix jointly promote the improvement of the performance of slurry coated gangue machine-made sand. However, in the prior art, during the slurry coating process of gangue machine-made sand, the surface slurry of the gangue machine-made sand is uneven, and the strength of the gangue machine-made sand cannot be effectively improved.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] like Figure 1 and Figure 2As shown, the present application provides a device for improving the quality of coal gangue machine-made sand, which includes a fixed frame 10, a box 20, a vibration structure 30 and a heating fan 40. The box 20 can be shakenly arranged on the fixed frame 10, and the box 20 has a mixing chamber 211, a material inlet 212, a material outlet 213, a drying channel 214 and a grouting inlet 215. The material inlet 212, the material outlet 213, the drying channel 214 and the grouting inlet 215 are all connected to the mixing chamber 211. The grouting inlet 215 is located at the top of the box 20. The material inlet 212 is used to transport the coal gangue machine-made sand into the mixing chamber 211, the grouting inlet 215 is used to transport the slurry into the mixing chamber 211, and the material outlet 213 is used to discharge the coal gangue machine-made sand mixed with the slurry. The vibration structure 30 is connected to the box 20 to drive the box 20 to vibrate. The heating fan 40 is connected to the drying channel 214 to dry the coal gangue machine-made sand after being mixed with the slurry.

[0044] By applying the technical solution of the present application, the gangue machine-made sand is poured into the mixing chamber 211 through the material inlet 212, and the prepared slurry is injected into the mixing chamber 211 through the grouting inlet 215, and the vibration structure 30 is turned on. After all the gangue machine-made sand is evenly coated with the slurry, the vibration structure 30 is kept turned on, and the heating fan 40 is turned on at the same time. After the slurry on the surface of the gangue machine-made sand is dried, the heating fan 40 is turned off, so that the slurry-coated gangue machine-made sand is discharged through the material outlet 213. With the above structure, the vibration structure 30 allows the slurry to fully contact with the gangue machine-made sand, thereby achieving uniform mixing of the slurry and the gangue machine-made sand, and then the surface of the gangue machine-made sand is evenly coated with slurry, avoiding the problem of uneven slurry coating by traditional manual or simple mechanical methods, and improving the slurry coating efficiency. Moreover, such a configuration can significantly improve the strength and durability of the coal gangue machine-made sand, making its performance closer to or reaching the standard of natural sand, thereby enhancing the application performance of the coal gangue machine-made sand in building materials such as concrete. At the same time, the heating fan 40 is connected to the drying channel 214, which can quickly dry the coal gangue machine-made sand after slurry coating, shorten the waiting time from the slurry coating of the coal gangue machine-made sand to the availability of the finished product, improve production efficiency, and at the same time avoid the subsequent slurry falling during the transportation of the coal gangue machine-made sand, ensure the structural strength of the coal gangue machine-made sand after slurry coating, reduce the slurry waste in the process of slurry coating of the coal gangue machine-made sand, and reduce production costs.

[0045] Specifically, in the present application, an observation window is provided at the material inlet 212. When the coal gangue machine-made sand is coated with slurry, the observation window is closed and the staff can observe the coating status through the observation window, so that the coating process is visualized, which is convenient for controlling the coating quality and monitoring the operating status of the equipment.

[0046] In the present application, the box body 20 is made of 304 stainless steel, and the wall thickness of the box body 20 is 10 mm.

[0047] Furthermore, the coal gangue machine-made sand upgrading device further includes a support assembly 50, which is arranged between the box body 20 and the fixed frame 10, and includes an elastic structure 51, which abuts against the box body 20. Such an arrangement ensures that the box body 20 is stably placed on the fixed frame 10, while enabling the box body 20 to shake relative to the fixed frame 10, ensuring the normal vibration of the vibration structure 30, thereby ensuring the uniformity of the slurry coating and the drying effect.

[0048] Specifically, the coal gangue machine-made sand upgrading device further includes a slurry delivery component 60, which has a slurry outlet, which is connected to the grouting inlet 215, and the slurry delivery component 60 is used to provide slurry into the mixing chamber 211. Such a configuration facilitates the provision of slurry into the mixing chamber 211. Through the continuous slurry supply of the slurry delivery component 60, the continuous production of the coal gangue machine-made sand upgrading process can be achieved, the production efficiency can be improved, and the needs of large-scale production can be met.

[0049] The box body 20 includes a shell body 21 and a cover body 22 .

[0050] The shell 21 has a mixing chamber 211 , a material inlet 212 , a material outlet 213 , a drying channel 214 and a plurality of grouting inlets 215 . The plurality of grouting inlets 215 are located at the top of the shell 21 .

[0051] The cover body 22 is arranged on the top of the shell 21, and there is a buffer cavity between the cover body 22 and the shell 21, the buffer cavity is connected to multiple grouting inlets 215, and a connecting channel is arranged on the cover body 22, one end of the connecting channel is connected to the buffer cavity, and the other end of the connecting channel is connected to the grout outlet.

[0052] In this way, the presence of the buffer chamber can ensure that the slurry is evenly distributed in the space between the cover 22 and the shell 21 before entering the shell 21, avoiding the uneven or local aggregation phenomenon that may occur during direct grouting. Through multiple grouting inlets 215, the slurry can be more evenly covered on the surface of the coal gangue machine-made sand, improving the coating effect and the surface strength of the coal gangue machine-made sand. At the same time, the above structure is adopted to facilitate the processing of the box body 20 and is simple to operate.

[0053] Furthermore, in the present application, 69 grouting inlets 215 are provided on the top of the shell 21 .

[0054] Specifically, in the present application, the shell 21 and the cover body 22 are rectangular structures. The cover body 22 is 90 cm long and 50 cm wide. A buffer cavity is provided inside the cover body 22. The buffer cavity is 2 mm deep and 80 cm in diameter. The buffer cavity covers the range of multiple grouting inlets 215 to ensure that all grouting inlets 215 are evenly permeated with slurry.

[0055] The box body 20 has a material storage chamber 216 , which is connected to the material outlet 213 . A baffle 23 is slidably arranged between the material storage chamber 216 and the mixing chamber 211 , and the baffle 23 can separate the material storage chamber 216 from the mixing chamber 211 .

[0056] With the above structure, after the slurry on the surface of the gangue machine-made sand is dried, the heating fan 40 and the vibration structure 30 are turned off, and the baffle 23 is pulled out, so that the gangue machine-made sand passes through the storage cavity 216 and is discharged from the material outlet 213. Such a configuration is convenient for controlling the discharge of the gangue machine-made sand, and has a simple structure and convenient operation.

[0057] Furthermore, in the present application, a slide groove is provided in the box body 20, and the baffle 23 is movably provided in the slide groove. Such a setting can ensure the stability of the movement of the baffle 23.

[0058] Specifically, in the present application, when the baffle 23 is in a completely blocked state, the length, width and height of the baffle 23 inside the box 20 are 50 cm, 50 cm and 2 cm respectively, and the dimensions outside the box 20 are 3 cm, 50 cm and 0.7 cm. The baffle 23 is made of 304 stainless steel.

[0059] Among them, the storage chamber 216 is located below the mixing chamber 211, and a guide portion 217 is provided between the storage chamber 216 and the mixing chamber 211, and the guide portion 217 gradually tilts from the direction close to the baffle 23 to the direction away from the grouting inlet 215. In this way, the inclination angle design of the guide portion 217 can make the transition of the gangue machine-made sand between the mixing chamber 211 and the storage chamber 216 smoother, so that the gangue machine-made sand can quickly slip out of the material outlet 213 after being coated with slurry and dried, avoiding the blockage and accumulation of the gangue machine-made sand, and ensuring the continuity and stability of the production process.

[0060] Further, in the present application, the angle between the guide portion 217 and the horizontal plane is set to 7°.

[0061] Specifically, the fixing frame 10 has a through hole, the box body 20 is inserted in the through hole, the box body 20 has a mixing part 218 and a discharging part 219, the mixing part 218 has a mixing chamber 211, the discharging part 219 has a material outlet 213, the mixing part 218 is located above the fixing frame 10, the discharging part 219 is located below the fixing frame 10, and the support assembly 50 is arranged between the mixing part 218 and the fixing frame 10. In this way, the through hole of the fixing frame 10 can accurately position the box body 20, ensuring that the box body 20 remains stable during operation, and at the same time, it is convenient for the support assembly 50 to support the box body 20, and at the same time, it can ensure the effect of the vibration structure 30 driving the box body 20 to vibrate.

[0062] Among them, the support assembly 50 also includes a first support frame 52 and a second support frame 53, and the first support frame 52 and the second support frame 53 are located on the fixed frame 10. The elastic structure 51 includes a first elastic member 511, a second elastic member 512 and a third elastic member 513. The first elastic member 511 is arranged between the bottom of the mixing part 218 and the first support frame 52. Such an arrangement facilitates the fixing of the first elastic member 511 to avoid the first elastic member 511 from deflecting during the telescopic process. The first support frame 52 can ensure that the first elastic member 511 can only swing up and down and not left and right, and at the same time limit the telescopic distance of the first elastic member 511 up and down to ensure safety.

[0063] The second elastic member 512 is disposed between the side wall of the mixing portion 218 and the second support frame 53. This arrangement facilitates fixing the second elastic member 512 and prevents the second elastic member 512 from deflecting during the expansion and contraction process.

[0064] The third elastic member 513 is disposed between the bottom of the mixing section 218 and the fixing frame 10, and the third elastic member 513 is sleeved on the box body 20. Such an arrangement can ensure the support effect of the box body 20 and the shaking effect of the box body 20. In addition, the first elastic member 511, the second elastic member 512 and the third elastic member 513 can effectively absorb and disperse vibration energy from different directions, ensuring the stability of the box body 20 during the slurry spreading and drying process.

[0065] Specifically, the first support frame 52 is a hollow cylindrical structure with an inner diameter of 5 cm and a height of 3 cm.

[0066] Furthermore, the second support frame 53 has a first support section and a second support section connected to each other.

[0067] Among them, in the present application, the second support frame 53 is 60cm long and 15cm high, the height of the first support section is 5cm, the height of the second support section is 10cm, the second support section is located above the first support section, and the width of the first support section is greater than the width of the second support section. A rectangular limiting groove is opened on the inner side of the second support section, and the limiting groove is 5cm deep. The second support frame 53 can ensure that the second elastic member 512 will only shake left and right, not up and down, and at the same time limit the extension distance of the second elastic member 512 to ensure safety.

[0068] Specifically, in the present application, the first elastic member 511 , the second elastic member 512 and the third elastic member 513 are springs.

[0069] Furthermore, the drying channel 214 is arranged on the side wall of the box body 20, and the drying channel 214 is arranged close to the grouting inlet 215. The drying channel 214 is gradually inclined from the direction close to the mixing chamber 211 to the direction away from the grouting inlet 215. Such an arrangement can ensure the smoothness of the high-temperature gas flowing in the drying channel 214, help the high-temperature gas flow to the surface of the coal gangue machine-made sand, help to accelerate the evaporation of water on the slurry surface, thereby improving the drying speed and efficiency.

[0070] The slurry delivery assembly 60 further includes a slurry storage box 61 and a connecting pipe 62. One end of the connecting pipe 62 is connected to the slurry storage box 61, and the other end of the connecting pipe 62 is a slurry outlet. The connecting pipe 62 is provided with a pressure pump 63, a pressure regulating valve 64 and a pressure gauge 65. With such a configuration, the pressure pump 63 can provide stable power to ensure that the slurry enters the mixing chamber 211 at a set flow rate and pressure, while the presence of the pressure regulating valve 64 and the pressure gauge 65 can monitor and adjust the pressure in the slurry delivery process in real time, avoiding the influence of pressure fluctuations on the uniformity of the slurry coating, and ensuring the precise control of the process parameters.

[0071] In addition, the gangue machine-made sand upgrading device needs to be tested for sealing before use. The specific operations are as follows:

[0072] Connect each experimental device in sequence, put a small amount of prepared slurry into the slurry storage box 61, open the pressure regulating valve 64, start the pressure pump 63, and let the slurry flow into the mixing chamber 211 through the connecting pipe 62 at a certain flow rate. Observe whether there is leakage at the connection between the connecting pipe 62, the shell 21 and the cover 22, and observe whether the pointer reading of the pressure gauge 65 is stable. After the sealing test is completed, close the pressure regulating valve 64 and the pressure pump 63 to release the pressure in the device.

[0073] Furthermore, after the batter coating is completed, the box 20 and the batter delivery assembly 60 are cleaned in time to prevent the batter from solidifying and clogging the device.
