Description

Technical Field

[0001] This invention relates to the field of basalt flake production, and more particularly to a basalt flake production apparatus. Background Technology

[0002] Basalt flakes are a new type of material made from basalt through special processes such as melting, homogenization, shaping, and recycling. In addition to high strength and high modulus, this material also possesses excellent properties such as high / low temperature resistance, acid and alkali resistance, oxidation resistance, radiation resistance, insulation, heat insulation, sound insulation, wear resistance, fire retardancy, and electromagnetic wave absorption. However, existing basalt flake production equipment requires a long cooling and shaping process after the basalt raw material is melted and homogenized before it can be transferred and output. Cooling and subsequent transfer consume a significant portion of the flake production time. Furthermore, the complex material discharge trajectory, the complex rotary discharge structure, and the cumbersome discharge process result in low discharge efficiency, leading to significant quality instability of basalt flakes under different discharge environments.

[0020] like Figure 1-5 A basalt flake production device includes: a forming device 1, a feeder 2, a discharge structure 3, and a combustion heating structure 5; The molding device 1 is provided with a molding cavity 11; the molding cavity 11 is provided with a bottom material trough 12, and a discharge platform 13 is provided on one side of the bottom material trough 12; the feeder 2 is installed on the molding device 1; the molding device 1 is also provided with a discharge cavity 14 adjacent to the discharge platform 13, the discharge platform 13 is provided with a discharge channel 131, and the molding cavity 11 and the discharge cavity 14 are connected through the discharge channel 131; the discharge structure 3 includes: a discharge rotor 31 and a discharge rotation driver 32. The discharge rotor 31 is located directly below the input end of the discharge chamber 14 and diagonally above the output end of the discharge chamber 14. The discharge rotor 31 and the output end of the discharge chamber 14 form a parabolic distance 310 in the horizontal direction. The output end of the discharge rotation driver 32 is connected to the discharge rotor 31 and is used to drive the discharge rotor 31 to rotate, so that the material falling to the discharge rotor 31 is transferred to the output end of the discharge chamber 14.

[0021] As a raw material conveying component in the upstream process, the feeder 2 has the core function of continuously and quantitatively conveying basalt raw material into the forming cavity of the forming machine 1 to provide raw material for the subsequent melting process. It is the feeding end of the production process. Combustion heating structure 5 is the core heating and melting component of the process. Its core function is to provide a high-temperature heat source for the basalt raw material in the forming cavity 11, so that the solid basalt raw material is heated and melted to form basalt melt. It is the key to realizing the transformation of raw material from solid to liquid. Forming Unit 1: As the core supporting cavity of the process, its internal forming cavity 11 is a melting cavity, responsible for providing a high-temperature enclosed space for melting raw materials. The discharge cavity 14 is a forming cavity, responsible for providing space for melt projection, cooling, and scaling. The two cavities work together to complete the core transformation from melt to scales; Discharge Structure 3: As the core component of the downstream forming and discharge process, its core actuator is the discharge rotor 31, which is the key actuator for realizing the transformation of melt into scales.

[0022] This solution provides a basalt flake production device, which outputs basalt raw material to the bottom material tank 12 through the feeder 2, and melts the raw material into a melt through heating. After the melt fills the bottom material tank 12, it is transferred to the discharge platform 13 and output to the discharge chamber 14 through the discharge channel 131. Then, the basalt melt is thrown to the output end of the discharge chamber 14 by the discharge rotor 31. Thus, the melt can be discharged, cooled and dispersed into basalt flakes under the rotation of the discharge rotor 31. This solves the problem of unstable quality of the formed flakes due to low discharge efficiency in existing basalt flake production devices.

[0023] Specifically, the material is basalt; the molding device 1 is provided with a molding cavity 11; the molding cavity 11 is provided with a bottom material trough 12, and the feeder 2 outputs basalt raw material to the molding cavity 11; the molding cavity 11 has a heating function, which can melt the basalt to form basalt melt; the basalt melt is distributed in the bottom material trough 12, and since the discharge platform 13 is set on one side of the bottom material trough 12; when the amount of basalt melt is large enough to fill the bottom material trough 12, as the basalt melt continues to increase, the melt will overflow onto the upper surface of the discharge platform 13 on one side of the bottom material trough 12, and the melt passes through the discharge channel 131 of the discharge platform 13; the basalt melt is transferred from the molding cavity 11 to the discharge cavity 14 through the discharge platform 13; the discharge cavity 14 is provided with an input end for receiving basalt melt, and a discharge end for discharging basalt melt. The output end; when the basalt melt enters the discharge chamber 14, it falls to the discharge rotor 31 below under the action of gravity or negative pressure. The discharge rotor driver 32 can be pre-activated. The output end of the discharge rotor driver 32 drives the discharge rotor 31 to rotate. After the basalt melt falls and contacts the discharge rotor 31, the rotation of the discharge rotor 31 will drive the basalt melt to fall and move horizontally along the tangential direction of the rotation range of the discharge rotor 31. The discharge rotor 31 and the output end of the discharge chamber 14 form a parabolic distance 310 in the horizontal direction. After the basalt melt falls, it can obtain a speed towards the output end of the discharge chamber 14. Under the action of gravity, the basalt melt can be quickly output to the output end of the discharge chamber 14 in a parabolic manner, realizing the rapid discharge of the basalt melt. Meanwhile, during the transfer of the basalt melt to the output end of the discharge chamber 14, the discharge rotor 31 accelerates the airflow within the discharge chamber 14 through rotation. This not only expels hot air from the discharge chamber 14 but also introduces fresh air, ensuring full contact between the basalt melt and the air. This allows the basalt melt to cool rapidly and form flakes. Furthermore, the rotation of the discharge rotor 31 provides shearing force, which breaks up the basalt flakes and inhibits their agglomeration during cooling, thus ensuring the dimensional stability of the basalt flakes.

[0024] The discharge rotary drive 32 is a known mechanism with a rotary drive function, such as a motor or a combination of a motor and a reducer, as long as it can drive the rotation of the discharge rotor 31.

[0025] The bottom material tank 12 serves as a melt buffer storage structure within the molding cavity. Its core function is to receive and accommodate the basalt melt generated by the combustion heating structure, forming a buffer space for the melt. This prevents the melt transport from becoming too fast or too slow due to fluctuations in the feeding and melting rates, ensuring that the subsequent molding process can maintain a continuous and stable melt transport.

[0026] The discharge platform 13 is a melt guide and support structure on the other side of the bottom material tank 12. Its core function is to guide the melt overflowing from the bottom material tank 12 to flow towards the discharge channel 131. It is a transition structure connecting the bottom material tank 12 and the discharge channel 131, allowing the melt to enter the discharge chamber 14 from the forming chamber 11 along a preset path. The bottom material tank 12 and the discharge platform 13 are arranged side by side in the horizontal direction. Through the fixed path design of the bottom material tank 12, the discharge platform 13 and the discharge channel 131, the high-temperature melting zone and the projectile forming zone are orderly connected and physically separated. The material conveying is naturally driven by gravity, eliminating the need for additional pumps, valves and other forced conveying devices. This avoids corrosion damage to precision components by the high-temperature melt, reduces equipment maintenance costs, and fits the practical design concept of the patent.

[0027] The discharge channel 131 is offset from the rotation center of the discharge rotor 31, causing the melt to fall outside the middle of the rotor's rotation range. If it falls to the center of the rotor, the centrifugal force is insufficient, and the melt cannot be effectively projected. By limiting the melt to fall precisely into the effective working area from the middle to the outer ring of the rotor, it is ensured that the rotor rotation can provide sufficient tangential velocity for the melt, achieving stable parabolic discharge.

[0028] This solution integrates melt projection, shearing, cooling, and scaling through the rotation of the discharge rotor 31. After the basalt melt enters the discharge chamber from the forming cavity, it contacts the discharge rotor. The rotation of the discharge rotor simultaneously drives the realization of three core functions: Provides horizontal projection velocity: imparts horizontal power to the melt, causing the melt to move toward the output end of the discharge chamber in a parabolic trajectory, thereby achieving rapid discharge of the melt and solving the problem of low discharge efficiency in existing devices; Shear force that forms the broken melt: The rotation of the propeller generates a strong shear force on the viscous basalt melt, breaking it into uniform small droplets, effectively preventing the melt from agglomerating during the cooling process and ensuring the size uniformity of the final flake product; Accelerated airflow promotes cooling and molding: The rotation of the paddle drives the air in the discharge chamber to flow rapidly. On the one hand, it promptly discharges the hot air in the chamber, and on the other hand, it continuously introduces cold air, so that the broken melt droplets can fully contact the air and be quickly cooled and molded into basalt flakes, thus achieving the simultaneous completion of discharge and molding.

[0029] Optimally, the combustion heating structure 5 includes multiple combustion heating components; at least one combustion heating component is located at the feeder 2 to heat the basalt raw material entering the forming cavity 11; at least one combustion heating component is located above the discharge platform 13 to heat the basalt melt overflowing from the bottom material trough 12. The combustion heating structure 5 is not a single unit, but is composed of multiple combustion heating components. Each component is an independent execution unit of the combustion heating structure and can independently realize the heating function; the multiple combustion heating components adopt a fixed-point layout and are divided into two core heating areas according to the process steps.

[0030] The feeder 2 is the inlet for solid basalt raw material to enter the molding cavity. The heating component here directly heats the solid basalt raw material that has just entered the molding cavity 11. On the one hand, it provides an initial melting heat source for the raw material, accelerates the conversion of solid raw material into melt, and improves the overall melting efficiency; on the other hand, it can preheat the raw material to raise its temperature, so that the raw material can quickly reach the melting temperature and reduce the overall heating energy consumption of the molding cavity.

[0031] The discharge platform 13 is a critical conveying node for the melt after it overflows from the bottom trough 12 and before entering the discharge channel 131. Basalt melt has the characteristics of being easily fusible at high temperatures and easily solidifying at low temperatures. If the temperature of the melt decreases during the conveying process of the discharge platform 13 and the discharge channel 131, problems such as sticking to the wall, solidification, and increased viscosity are very likely to occur, resulting in poor melt conveying and decreased melt uniformity. The heating components here provide real-time heating and constant temperature maintenance for the flowing melt, ensuring that the melt is always in a stable molten state before entering the discharge channel and falling to the discharge rotor 31. This avoids changes in melt properties due to temperature fluctuations and ensures that the melt can be uniformly sheared and projected by the rotor after falling onto the rotor.

[0032] Preferably, the combustion heating structure 5 includes: a combustion chamber 51, an exhaust pipe 52, and a gas pipe 53; the combustion heating structure 5 is as shown in the attached figure. Figure 2 As shown.

[0033] The combustion chamber 51 is provided with an oxygenation chamber 511 and a mixing chamber 512 connected to each other from top to bottom; the output end of the gas outlet pipe 52 is connected to the input end of the oxygenation chamber 511, and is used to input air or oxygen into the oxygenation chamber 511; the output end of the gas pipe 53 extends into the mixing chamber 512, and is used to output combustible gas into the mixing chamber 512; the output end of the mixing chamber 512 is connected to the forming chamber 11. Preferably, the combustion heating structure 5 is further provided with a cooling device 54. A temperature control groove 513 is provided between the inner and outer walls of the mixing chamber 512, and the cooling device 54 is installed in the temperature control groove 513.

[0034] Specifically, the outlet pipe 52 can draw in air (or oxygen, the same below) and output the air to the oxygenation chamber 511. Since the main part of the gas pipe 53 is installed in the oxygenation chamber 511, the air coming out of the outlet pipe 52 can fully contact the outer wall of the gas pipe 53, thereby preheating the combustible gas in the gas pipe 53 and ensuring that the temperature of the combustible gas is close to that of the air. At the same time, the output end of the gas pipe 53 extends into the mixing chamber 512. When the gas pipe 53 outputs combustible gas, it can create a negative pressure at the connection between the mixing chamber 512 and the oxygenation chamber 511. Under the action of the negative pressure, the air in the oxygenation chamber 511 is accelerated to be output to the mixing chamber 512.

[0035] A temperature control groove 513 is provided between the inner and outer walls of the mixing chamber 512, and a cooling device 54 can be installed in the temperature control groove 513. Because the mixing chamber 512 has high combustion efficiency, it remains at a high temperature for extended periods, which can lead to thermal expansion, thermal stress, and corrosion, thus reducing the service life of the combustion heating structure 5. This solution also provides a temperature control groove 513 between the inner and outer walls of the mixing chamber 512. The cooling device 54 within the temperature control groove 513 can remove some of the heat from the mixing chamber 512, thereby preventing the mixing chamber 512 from experiencing a reduced service life due to prolonged overheating. Thus, this solution can both improve the uniformity of gas mixing to increase combustion efficiency and solve the problem of reduced service life caused by excessively high combustion efficiency.

[0036] The cooling device 54 is a mechanism with a cooling function, which only needs to lower the temperature of the temperature control tank 513. In one embodiment, the cooling device 54 is provided with a cooling pipe 541; the cooling pipe 541 is installed in the temperature control tank 513; a cooling medium is introduced into the cooling pipe 541. The cooling medium, such as water, ice, or air, can carry away the heat from the temperature control tank 513 through the cooling pipe 541, thereby removing the heat from the mixing chamber 512 and preventing the temperature of the mixing chamber 512 from becoming too high.

[0037] The mixing chamber 512 includes, in sequence, an acceleration section 5121, a gas output section 5122, and a mixing section 5123; the inner radial direction of the acceleration section 5121 gradually decreases towards the gas output section 5122; the output end of the gas pipe 53 is located at the gas output section 5122; and the mixing section 5123 is provided with the temperature control groove 513.

[0038] The inner diameter of the accelerating section 5121 gradually decreases. With a constant flow rate, this reduced inner diameter increases the air velocity at the gas output section 5122, improving the mixing efficiency of air and combustible gas. Simultaneously, the mixing section 5123 is equipped with a temperature control groove 513, which is the main contact area between air and combustible gas. The cooling device 54 of the temperature control groove 513 effectively prevents the temperature of the mixing section 5123 from becoming too high. The outer wall of the gas pipe 53 forms a mixing gap 530 with the inner wall of the mixing chamber 512. Air can enter the mixing chamber 512 through this mixing gap 530, effectively surrounding the combustible gas and ensuring sufficient contact and mixing between the air and the combustible gas, thereby improving the combustion efficiency of the combustible gas.

[0039] The inner radial direction of the mixing section 5123 gradually increases away from the gas output section 5122.

[0040] The inner diameter of the mixing section 5123 gradually increases, and the inner radial direction increases away from the gas output section 5122. When the flow rate remains constant, the increase in inner diameter can reduce the flow rate when air and combustible gas are mixed, thereby prolonging the mixing time of air and combustible gas and the combustion time, thus improving the combustion efficiency of combustible gas.

[0041] The combustion chamber 51 may be equipped with an igniter in the oxygen supply chamber 511 and the mixing chamber 512 as needed. The preferred option is to install the igniter in the mixing chamber 512, and the optimal option is to install it in the mixing section 5123.

[0042] Optimally, it also includes: an intake structure 6; the intake structure 6 is as shown in the attached figure. Figure 3 As shown.

[0043] The air intake structure 6 includes: an inner cylinder 61 and an outer cylinder 62; The inner cylinder 61 has a heating channel 611 on its inner side, which is connected to the molding cavity 11; the inner cylinder 61 has a clamping groove 612 on the outer edge of the heating channel 611; the input end of the air outlet pipe 52 is connected to the clamping groove 612, which is used to input air or oxygen into the air outlet pipe 52; the output end of the mixing chamber 512 is connected to the molding cavity 11. The outer cylinder 62 is sleeved on the outside of the inner cylinder 61; the outer cylinder 62 is provided with an air inlet groove 621; the opening of the air inlet groove 621 faces downward and is located at the bottom of the outer cylinder 62; the opening of the clamping groove 612 faces upward and is located inside the air inlet groove 621, and an air inlet gap 622 is formed between the inner wall of the opening of the air inlet groove 621 and the outer wall of the inner cylinder 61; the air inlet groove 621 communicates with the clamping groove 612 and forms an air inlet channel 623.

[0044] The inner cylinder 61 is provided with a heating channel 611, and a clamping groove 612 is provided on the outer edge of the heating channel 611. The clamping groove 612 can be used to contain air, thereby outputting the air to the air outlet pipe 52, and then outputting it to the oxygenation chamber 511 through the air outlet pipe 52. The output end of the mixing chamber 512 is connected to the forming chamber 11. After the mixed gas in the forming chamber 11 flows through the forming chamber 11, it can be output from the heating channel 611. The mixing chamber 512, the forming chamber 11 and the heating channel 611 are connected in sequence. When air and combustible gas are mixed and burned in the mixing chamber 512, they pass through the forming chamber 11. The exhaust gas of the forming chamber 11 can pass through the heating channel 611 and use the residual heat of the exhaust gas to heat the air in the clamping groove 612, thereby making full use of the heat of the exhaust gas and improving the heat utilization rate.

[0045] The inner cylinder 61 has a heating channel 611 on its inner side, into which a heating medium can be introduced to heat the heating channel 611. The heating channel 611 then transfers heat to the outer edge of the heating channel 611, which has a clamping groove 612. This groove heats the gas in the air intake channel 623, allowing the external gas to maintain a specific temperature after entering the air intake structure 6. The outer cylinder 62 is installed on the inner cylinder 61, either at the end or side of the inner cylinder 61. The outer cylinder 62 has an air intake groove 621, with its opening facing downwards and located at the bottom of the outer cylinder 62. During air intake, gas is drawn in through the opening of the air intake groove 621, and the gas enters the air intake groove 621 from the bottom upwards. The clamping groove 612 has its opening facing upwards and located inside the air intake groove 621. Because the opening directions of the input end of the clamping groove 612 and the input end of the air inlet groove 621 are different, after the gas enters the clamping groove 612 from bottom to top, it needs to move horizontally before entering the upward-opening clamping groove 612. Furthermore, an air inlet gap 622 is formed between the inner wall of the opening of the air inlet groove 621 and the outer wall of the inner cylinder 61. The size of the air inlet gap 622 can be controlled to restrict the entry of solid particles. Thus, on the one hand, solid particles in the gas will not be able to enter the downward-opening air inlet groove 621 under the influence of gravity, and therefore cannot enter the air inlet channel 623. On the other hand, the size of the air inlet gap 622 can be designed, or the air inlet gap 622 can be physically filled, to control the size of the air inlet gap 622, thereby isolating solid particles in the gas and achieving the function of preliminary impurity removal during air intake. Therefore, the air intake structure 6 of this scheme can simultaneously perform air intake, impurity removal, and heating, realizing the impurity removal and heating functions during gas intake, solving the problem of separate steps for air intake, impurity removal, and heating in existing air intake structures 6.

[0046] The ratio of the inner diameter of the clamping groove 612 to the air intake gap 622 is 1:(4-7), or the ratio of the inner diameter of the clamping groove 612 to the air intake gap 622 is (4-7):1. This design allows the inner diameter of the clamping groove 612 to be designed to be smaller or larger than the air intake gap 622. The ratio of larger or smaller should be controlled so that the ratio of the inner diameter of the clamping groove 612 to the air intake gap 622 is 1:(4-7), or the ratio of the inner diameter of the clamping groove 612 to the air intake gap 622 is (4-7):1. That is, during air intake, solid particles in the gas are restricted from entering through the smaller air intake gap 622, or during air intake, solid particles in the gas are restricted from entering through the smaller opening of the clamping groove 612. In the optimal embodiment, the ratio of the inner diameter of the clamping groove 612 to the air inlet gap 622 is 1:(4-7). In this embodiment, more gas is drawn in from outside the air inlet groove 621, and solid particles in the gas cannot enter the opening of the air inlet groove 621, let alone the smaller opening of the clamping groove 612. At the same time, with this ratio, the inner diameter of the air inlet channel 623 outside the inner cylinder 61 is moderate, and the heat transfer from the heating channel 611 to the air inlet channel 623 is most uniform.

[0047] The clamping grooves 612 are distributed along the extending direction of the inner cylinder 61; the output end of the heating channel 611 is located above the input end; the outer cylinder 62 is installed on the upper end of the inner cylinder 61 and is close to the output end of the heating channel 611. The inner cylinder 61 can be regarded as an exhaust pipe, which is used for exhausting and venting smoke. The exhaust medium has residual heat, and this solution can utilize the residual heat of the medium in the exhaust pipe to heat the intake channel 623, making full use of the heat of the exhaust medium, improving the heat utilization rate, and eliminating the need for additional intake heating costs. The output end of the heating channel 611 is located above the input end, meaning the output end of the exhaust pipe is at the top and the input end is at the bottom. When the outer cylinder 62 is installed at the output end of the heating channel 611, the gas input from the air inlet 621 comes into contact with the medium passing through the output end of the heating channel 611, and its temperature is lower than that at the input end of the heating channel 611. As the gas is gradually transported along the lower end of the exhaust pipe, the gas can gradually heat up and reach the highest temperature at the input end of the heating channel 611. This structure can extend the heating time of the gas, thereby making the incoming gas more evenly and fully heated. At the same time, the outer cylinder 62 is installed above the inner cylinder 61, further away from the ground, which can prevent the intake of solid particles from the ground.

[0048] Optimally, the discharge rotor 31 is positioned near the inner wall of the discharge chamber 14 on the outer edge of its rotation range; the inner wall of the discharge chamber 14 is provided with an inclined surface 141; the inclined surface 141 gradually slopes downwards from the top towards the outer edge of the rotation range of the discharge rotor 31. The discharge structure 3 is detailed in the attached figure. Figure 4 As shown. Inclined plane 141 is attached. Figure 5 As shown.

[0049] The discharge rotor 31 is preferably located close to the inner wall of the discharge chamber 14. The advantage of this embodiment is that the discharge rotor 31 can be closer to the inner wall of the discharge chamber 14 on the outer ring when rotating, thereby reducing the distance between the outer ring of the rotation range and the inner wall of the discharge chamber 14. This prevents the material from falling between the outer ring and the inner wall of the discharge chamber 14, and thus prevents the material from falling to the position of the discharge rotor drive 32. This greatly increases the probability that each unit of material will be thrown to the output end of the discharge chamber 14 after falling.

[0050] The inner wall of the discharge chamber 14 is provided with an inclined surface 141. The space above the outer ring of the discharge rotor 31 can be omitted by the inclined surface 141. This can prevent the material from passing over the discharge rotor 31 and allow the material to move along the inclined surface 141 when it comes into contact with the outer ring. This guides the material to the middle of the rotation range of the discharge rotor 31, which greatly increases the probability that each unit of material will be thrown to the output end of the discharge chamber 14 after falling.

[0051] Further optimized, the molding device 1 has an output opening 142 at the output end of the discharge chamber 14, the upper end of the output opening 142 is connected to the discharge chamber 14, and the lower end of the output opening 142 is connected to the outside of the molding device 1; the discharge chamber 14 has a discharge guide plate 143 on one side wall of its output end, and the discharge guide plate 143 extends downward to the output opening 142.

[0052] The output end of the discharge chamber 14 is preferably provided with an output opening 142. The output opening 142 can be vertical or inclined, and a height difference is formed between the two ends of the output opening 142. When the material is transferred to the upper end of the output opening 142, it can fall to the lower end of the output opening 142 by its own gravity. The output opening 142 can restrict the direction of material discharge, so that the material discharge is restricted to a certain area. The vertical or inclined design can eliminate the need for mechanical devices to provide power for material discharge, which can simplify the discharge trajectory of the formed scales to improve the discharge efficiency of the scales and save the energy required for the discharge drive.

[0053] The discharge guide plate 143 is vertically arranged, and its lower end extends to the output opening 142. There may be differences in parameters between each unit of scale, resulting in differences in the actual output horizontal distance. The discharge guide plate 143 is set on the inner wall of the discharge cavity 14. Each unit of scale can be horizontally thrown to different height positions of the discharge guide plate 143. The discharge guide plate 143 can guide the scale to the output opening 142, which can prevent the scale from remaining in the discharge cavity 14 and ensure that the scale of each unit is concentrated in a specific output area.

[0054] The discharge structure 3 further includes: a discharge constant temperature heater 33; the molding machine 1 has an input opening 144 at the input end of the discharge chamber 14; the input opening 144 is vertically oriented toward the discharge rotor 31; the discharge constant temperature heater is installed in the input opening 144.

[0055] The input opening 144 can guide the material from the forming cavity 11 to the discharge cavity 14, so that the material can fall into the discharge rotor 31 under the action of gravity through the input opening 144. The angle when the material contacts the discharge rotor 31 can be adjusted. The angle of the input opening 144 can be set as needed, such as vertical extension or inclined extension.

[0056] The input opening 144 is located directly above the discharge rotor 31. Specifically, the input opening 144 can be positioned between the middle and the outer ring of the rotation range of the discharge rotor 31, ensuring that the material falls within the outer ring after entering through the input opening 144. This prevents the material from passing between the outer ring and the inner wall of the discharge chamber 14, significantly increasing the probability that each unit of material will be thrown towards the output end of the discharge chamber 14. Furthermore, this design also includes a discharge constant-temperature heater, such as a conventional heating wire or heating rod, at the input opening 144. This ensures that each unit of molten material falls to the discharge rotor 31 at a consistent temperature, further homogenizing the shape and size of the ejected molten material droplets.

[0057] Optimally, the molding device 1 has a material leakage opening 145 below the discharge rotor 31. The upper end of the material leakage opening 145 is connected to the discharge chamber 14, and the lower end of the material leakage opening 145 is connected to the outside of the molding device 1. The material leakage opening 145 is located within the rotation range of the discharge rotor 31. The output end of the discharge rotor drive 32 passes through the material leakage opening 145 from bottom to top and is connected to the discharge rotor 31.

[0058] The material leakage opening 145 is located below the discharge rotor 31 and aligned within the rotation range of the discharge rotor 31. When material passes between the outer ring of the discharge rotor 31 and the inner wall of the discharge chamber 14, it can either fall directly to the outside of the molding machine 1 or be received or recycled directly below the material leakage opening 145. For the embodiment of receiving material at the material leakage opening 145, the same container can be placed directly below the output opening 142 and the material leakage opening 145. For the embodiment of recycling material at the material leakage opening 145, the material transfer path is basically the same if the material parameters (e.g., mass, particle size, composition, etc.) are the same. If material appears at the material leakage opening 145, it can be considered that the parameters of the material are different from other materials output from the output end of the discharge chamber 14. The output end of the discharge rotary driver 32 passes through the discharge opening 145 from bottom to top and is connected to the discharge rotor 31. This eliminates the need to place the discharge rotary driver 32 inside the discharge chamber 14, thus preventing material from falling directly onto the surface of the discharge rotary driver 32 and avoiding damage to it.

[0059] Optimally, it also includes: a cooling component 8; The cooling component 8 has a cooling function; the cooling component 8 is installed in the discharge chamber 14 and is located below the discharge rotor 31 and above the discharge opening 145.

[0060] The cooling component 8 is a conventional mechanism with a known cooling function, such as a cooling pipe 81 or a cooling tank, as long as it can provide cooling for the discharge chamber 14. Generally, the material output from the forming chamber 11 to the discharge chamber 14 is at a high temperature, and it is easy to cause damage if it comes into direct contact with the discharge component 3 or other discharge mechanisms. In addition, it requires additional cooling after discharge, which prolongs the time after discharge. By setting the cooling component 8 in the discharge chamber 14, the heat in the discharge chamber 14 can be removed in time, which not only avoids the material temperature from becoming too high and effectively protects the components, but also shortens the cooling time of subsequent materials to a certain extent.

[0061] In one embodiment, the cooling assembly 8 includes a cooling pipe 81; the cooling pipe 81 is installed in the discharge chamber 14 and is located below the discharge rotor 31.

[0062] The cooling pipe 81 is located in the discharge chamber 14, below the discharge rotor 31. Cooling medium can be introduced into the cooling pipe 81. The cooling medium at a specific temperature can control the temperature of the cooling pipe 81, thereby removing the heat from the discharge rotor 31 in the discharge chamber 14 and cooling the material. The cooling medium is a low-temperature medium, such as dry ice, water, air, ice, etc.

[0063] Optimally, it also includes: current limiting block 4; The flow-limiting block 4 is installed in the forming cavity 11 and extends into the bottom material tank 12. The lower part of the flow-limiting block 4 forms a flow-limiting gap 40 with the bottom wall of the bottom material tank 12. The flow-limiting gap 40 is used to limit the liquid level of the basalt melt in the bottom material tank 12 and to cause the basalt melt overflowing from the bottom material tank 12 to flow towards the discharge platform 13.

[0064] This design preferably includes a flow-limiting block 4 within the molding cavity 11. When the bottom of the flow-limiting block 4 is close to the bottom wall of the bottom material tank 12, it is equivalent to the flow-limiting block 4 occupying space in the bottom material tank 12. The larger the flow-limiting gap 40, the more space the flow-limiting block 4 occupies in the bottom material tank 12; the smaller the flow-limiting gap 40, the more space the flow-limiting block 4 occupies in the bottom material tank 12. This allows the basalt melt to fill the bottom material tank 12 more quickly, thus causing the basalt melt to overflow onto the discharge platform 13 more quickly, and shortening the residence time of the basalt melt in the molding cavity 11. The larger the flow-limiting gap 40... The flow limiting block 4 occupies more space in the bottom material tank 12, causing the basalt melt to fill the bottom material tank 12 more slowly. This delays the overflow of the basalt melt to the discharge platform 13 and prolongs the residence time of the basalt melt in the forming cavity 11. Thus, this solution can control the residence time of the basalt melt by positioning the flow limiting block 4 in the bottom material tank 12, thereby controlling the time from output to the discharge rotor 31. Different melt residence times can be set for basalt raw materials with different characteristics, making the quality of the basalt melt controllable and the forming efficiency higher.

[0065] In one embodiment, the flow-limiting block 4 is fixedly installed in the molding cavity 11. When replacement is required, the flow-limiting block 4 is disassembled and replaced with a flow-limiting block 4 of a different size, thereby adjusting the position of the flow-limiting block 4 in the bottom material trough 12. In another embodiment, the flow-limiting block 4 is movably installed in the molding cavity 11 by a known mechanism with a driving function, such as a cylinder, hydraulic cylinder, a combination of a motor and a lead screw, or a motor, as long as it can drive the rotation or linear movement of the flow-limiting block 4.

[0066] Optimally, the molding cavity 11 is provided with a feeding platform 15 between the bottom wall and the side wall; the feeding platform 15 and the discharge platform 13 are separated by the bottom material trough 12; the output end of the feeder 2 faces the feeding platform 15; the upper surface of the feeding platform 15 is higher than the lower surface of the discharge platform 13. The lower end of the flow limiting block 4 is located between the upper surface of the feed platform 15 and the lower surface of the discharge platform 13.

[0067] The flow-limiting block 4 extends into the bottom material tank 12, which can divide the forming cavity 11 into a feeding area 111 and a discharging area 112. The feeding platform 15 is set at the output position of the feeder 2. The feeding platform 15 occupies most of the feeding area. In particular, it is set between the bottom wall and the side wall of the forming cavity 11, which can prevent the basalt melt from being stuck in the corner of the forming cavity 11 for a long time and difficult to discharge. At the same time, the basalt melt basically falls into the bottom material tank 12 under the action of gravity after being output by the feeder 2, and the basalt melt will no longer fill the bottom wall and side wall, so that the bottom material tank 12 can be filled more quickly. Furthermore, the upper surface of the feeding platform 15 is higher than the lower surface of the discharging platform 13. The liquid level of the basalt melt only needs to be higher than the upper surface of the discharging platform 13 to flow into the discharge channel 131. Therefore, the basalt melt will not remain on the side wall and top wall of the forming cavity 11, so that the forming rate of the basalt melt is higher.

[0068] The basalt melt only needs to be above the upper surface of the discharge platform 13 to flow into the discharge channel 131. The lower end of the flow limiting block 4 is located between the upper surface of the feed platform 15 and the lower surface of the discharge platform 13, which can form an exhaust gap between the lower end of the flow limiting block 4 and the basalt melt surface. The airflow can transfer between the feed area and the discharge area. The temperature distribution in the feed area and the discharge area is uniform, which can make the basalt melt more uniform during feeding and discharging.

[0069] Optimally, it also includes: a discharge conveyor 9; The conveying end of the discharge conveying device 9 passes below the output end of the discharge chamber 14.

[0070] The discharge conveying device is a known mechanism with conveying function, such as a conveyor belt device, a conveyor roller structure, a conveyor turntable, a moving trolley, and a robotic arm structure, as long as it can receive the material output from the output end of the discharge chamber 14. The conveying end of the discharge conveying device 9 can pass below the output opening 142 and / or below the leakage opening 145.
