[0002] The core of the split flow structure design of the coal mill separator is to achieve the particle size classification of coal powder by adjusting the split flow path. Its fundamental function is to control the particle size of coal powder output by the coal mill to meet the needs of different process flows or product standards.

[0003] However, the current splitter structure of the conventional coal mill separator has encountered some challenges in its actual use, especially in the absence of drying equipment support. During the splitting process, the coal powder is prone to agglomeration, which significantly hinders the effective separation process. Due to the lack of drying equipment, the humidity of the coal powder during the splitting process cannot be properly controlled, resulting in the adhesion between the coal powder particles and the formation of agglomerations. The formation of these agglomerates makes the distribution of the coal powder in the splitter uneven, which in turn affects the classification effect of the separator and the overall quality of the coal powder.

[0040] The core of the split flow structure design of the coal mill separator is to achieve the particle size classification of coal powder by adjusting the split flow path. Its fundamental function is to control the particle size of coal powder output by the coal mill to meet the needs of different process flows or product standards.

[0041] However, the current splitter structure of the conventional coal mill separator has encountered some challenges in its actual use, especially in the absence of drying equipment support. During the splitting process, the coal powder is prone to agglomeration, which significantly hinders the effective separation process. Due to the lack of drying equipment, the humidity of the coal powder during the splitting process cannot be properly controlled, resulting in the adhesion between the coal powder particles and the formation of agglomerations. The formation of these agglomerates makes the distribution of the coal powder in the splitter uneven, which in turn affects the classification effect of the separator and the overall quality of the coal powder.

[0042] In view of this, the utility model aims at the deficiencies of the prior art and proposes a diversion structure of a double-adjustable diversion separator, aiming to solve the problem that the current transmission coal mill separator diversion structure lacks drying equipment, which makes coal powder easy to agglomerate, seriously affecting the diversion effect of coal powder and the quality of coal powder after diversion.

[0043] like Figure 1-Figure 2As shown, in some embodiments of the present invention, a diversion structure of a dual-adjustable diversion separator is provided, including: a diversion barrel 100, a hot air guide part, a multi-layer filter guide part and a support frame 400. The diversion barrel 100 is provided with a diversion space therein, and the diversion barrel 100 is used to store the coal powder to be diverted; the hot air guide part is arranged in the middle and lower part of the diversion barrel 100, one end of the hot air guide part is connected with the hot air blower, and the other end of the hot air guide part passes through the outer wall of the diversion barrel 100 and is connected with the diversion space, and the hot air guide part is used to guide the hot air to the diversion space; the multi-layer filter guide part is sleeved in the middle and upper part of the diversion barrel 100, wherein the multi-layer filter guide part is provided with a plurality of filter tubes, and one end of the plurality of filter tubes passes through the outer wall of the diversion barrel 100 and is connected with the diversion space, and the multi-layer filter guide part is used to filter and guide the coal powder to be diverted; the support frame 400 is arranged at the bottom of the diversion barrel 100, and the support frame 400 is connected to the outer wall of the diversion barrel 100, and the support frame 400 is used to support the diversion barrel 100.

[0044] It can be seen that by taking the diversion barrel 100 as the core component and providing a diversion space therein, this is the key to storing the coal powder to be diverted. Secondly, by the design that the hot air guide part is located in the middle and lower part of the diversion barrel 100, the diversion of the diversion space by hot air is realized. Such a design not only helps to remove the moisture in the coal powder to meet the needs of the diversion process, but also promotes the flow of coal powder in the diversion space by airflow impact, thereby enhancing the diversion effect. In addition, the multi-layer filter guide part is located in the middle and upper part of the diversion barrel 100. By setting a number of filter tubes and connecting them with the diversion space, the coal powder to be diverted is filtered and diverted. This step ensures the purity and quality of the coal powder during the diversion process and improves the quality of the product. Finally, the setting of the support frame 400 ensures the stability and reliability of the entire structure and provides basic support for the normal operation of the diverter.

[0045] It is understandable that, through the setting of the hot air diversion part, the coal powder is subjected to the action of hot air before entering the diversion space, which can effectively remove the moisture in the coal powder. Such treatment helps to reduce the agglomeration or adhesion of the coal powder that may be generated during the diversion process, improves the fluidity of the coal powder, and thus enhances the diversion effect. Secondly, the presence of the multi-layer filter guide part can filter and guide the coal powder to be diverted, ensuring the purity and quality of the coal powder. Through the setting of the filter tube, impurities or particles in the coal powder can be effectively removed, making the product after diversion purer and of higher quality, meeting the requirements of industrial production. In addition, the stability and reliability of the entire structure are guaranteed, which ensures that the diverter can operate stably for a long time, improves production efficiency and equipment reliability, and reduces maintenance costs and downtime.

[0046] In some embodiments of the utility model, the diverter barrel 100 includes: an upper barrel body 110, a feed hatch 120 and a lower barrel body 130. The upper barrel body 110 has a first cavity at its bottom, wherein a through hole is provided in the middle and lower part of the upper barrel body 110, and the through hole is connected to the first cavity; the feed hatch 120 is arranged on the outside of the upper barrel body 110, and the feed hatch 120 is arranged corresponding to the through hole, and one end of the feed hatch 120 is rotatably connected to the side wall of the upper barrel body 110; the lower barrel body 130 is arranged below the upper barrel body 110, and a second cavity is provided on the top of the lower barrel body 130, so that when the upper barrel body 110 is connected to the lower barrel body 130, a diverter space is formed between the first cavity and the second cavity.

[0047] Specifically, the structure of the diverter barrel 100 includes an upper barrel body 110, a feed hatch 120 and a lower barrel body 130. A first cavity is provided at the bottom of the upper barrel body 110, and a through hole is provided at the middle and lower part, and the through hole is connected to the first cavity. The feed hatch 120 is arranged on the outside of the upper barrel body 110, corresponding to the through hole, and one end is rotatably connected to the side wall of the upper barrel body 110. The lower barrel body 130 is located below the upper barrel body 110, and a second cavity is provided at the top thereof. When the upper barrel body 110 is connected to the lower barrel body 130, a diverter space is formed between the first cavity and the second cavity. The diverter barrel 100 of this design can realize the diverting effect of coal powder. First, the setting of the first cavity and the through hole of the upper barrel body 110, and the design of the feed hatch 120, can make the coal powder enter the first cavity through the feed port, and then enter the diverter space through the through hole. Such a structure ensures that the coal powder can smoothly enter the diversion space, providing a channel for subsequent diversion operations. Secondly, the design of the lower barrel 130 plays a role of connection and support. By connecting the lower barrel 130 with the upper barrel 110, a diversion space is formed between the first cavity and the second cavity. This structure enables the diversion barrel 100 to have a complete internal space, which can effectively store and process the coal powder to be diverted, thereby realizing the function of the diverter.

[0048] In some embodiments of the present invention, the lower barrel body 130 is an inverted cone structure, and two ventilation holes are provided in the middle and lower part of the lower barrel body 130, and the two ventilation holes are arranged opposite to each other.

[0049] In some embodiments of the present invention, the inner side wall of the first cavity is further provided with a plurality of first guide grooves 111 ; the inner side wall of the second cavity is further provided with a plurality of second guide grooves 131 , and the first guide grooves 111 and the second guide grooves 131 are provided correspondingly.

[0050] Specifically, the lower barrel body 130 is an inverted cone structure, and this design helps to guide the flow of coal powder during the diversion process and provides enough space to accommodate the diverted products. Two vents are also provided in the middle and lower part of the lower barrel body 130, and the two vents are arranged relative to each other. Such a setting helps to maintain ventilation inside the diversion space and ensure the stability of coal powder during the diversion process. Secondly, the inner side wall of the first cavity is provided with a plurality of first guide grooves 111, and the inner side wall of the second cavity is also provided with a plurality of second guide grooves 131, and these guide grooves are arranged correspondingly. The purpose of this design is to guide the flow trajectory of coal powder inside the diversion space through the action of the guide groove, so as to achieve a more accurate diversion effect. The corresponding arrangement of the first guide groove 111 and the second guide groove 131 further ensures the balanced distribution of coal powder during the diversion process and improves the accuracy and stability of the diversion.

[0051] It can be understood that through reasonable structural settings and channel design, the flow of coal powder can be guided and controlled, thereby improving the diversion efficiency and accuracy of the diverter. At the same time, the setting of the vents ensures ventilation inside the diversion space, which helps to maintain the stability and uniformity of the coal powder during the diversion process.

[0052] See also Figure 3 As shown, in some embodiments of the utility model, the hot air guide part includes: a hot air guide tube 210, a choke valve 220, a temperature detection unit 230 and a central control chip. The hot air guide tube 210 is provided with two groups, wherein one end of the hot air guide tube 210 is connected to the hot air blower, and the other end of the hot air guide tube 210 is connected to the second cavity through the vent hole; the choke valve 220 is arranged inside the other end of the hot air guide tube 210, and the choke valve 220 is fixedly connected to the inner wall of the hot air guide tube 210; the temperature detection unit 230 is arranged inside the hot air guide tube 210, and the temperature detection unit 230 is used to detect the temperature of the guided hot air; the central control chip is electrically connected to the temperature detection unit 230 and the choke valve 220 respectively, and the central control chip is used to adjust the opening angle of the choke valve 220 according to the temperature of the hot air.

[0053] Specifically, two groups are provided through the hot air guide tube 210, one end of which is connected to the hot air blower, and the other end is connected to the second cavity through the vent. Such a setting enables the hot air to be effectively diverted to the inside of the diversion space. Secondly, the air blocking valve 220 is arranged inside the other end of the hot air guide tube 210 and is fixedly connected to the inner wall of the hot air guide tube 210. The function of the air blocking valve 220 is to adjust the flow rate of the hot air and control the degree of influence of the hot air on the coal powder, so as to achieve precise control of the diversion process. In addition, the temperature detection unit 230 is arranged inside the hot air guide tube 210 to detect the temperature of the diverted hot air. Such a setting can monitor the temperature of the hot air in real time and provide data support for subsequent control. Finally, the central control chip is electrically connected to the temperature detection unit 230 and the air blocking valve 220, and is used to adjust the opening angle of the air blocking valve 220 according to the temperature of the hot air. By controlling the choke valve 220 through the central control chip, the choke valve 220 can be automatically adjusted according to the change of the hot air temperature, ensuring that the influence of the hot air on the coal powder is within an appropriate range, thereby achieving precise control of the diversion process.

[0054] Specifically, when the diverter is running, the coal powder in the feed contains different moisture and temperature. When the hot air guide pipe 210 introduces hot air into the diverter space, the temperature detection unit 230 detects the temperature of the hot air in real time. If the water content of the coal powder is high, resulting in a low temperature of the hot air, the central control chip will adjust the opening angle of the choke valve 220 according to this information. For example, if the temperature detection unit 230 detects that the hot air temperature is lower than the preset value, the central control chip sends a signal to the choke valve 220 to automatically adjust the opening angle. This will increase the opening degree of the choke valve 220, increase the hot air flow rate, and increase the temperature in the diverter space. On the other hand, if the temperature detection unit 230 detects that the hot air temperature is too high, the central control chip will reduce the opening angle of the choke valve 220 accordingly. This will reduce the hot air flow rate to reduce the temperature in the diverter space. Through such an automatic adjustment process, the hot air guide can dynamically adjust the impact of the hot air on the coal powder according to the actual situation, ensuring that the state of the coal powder during the diversion process is within the optimal range, thereby achieving precise control of the diversion process.

[0055] In some embodiments of the utility model, the multi-layer filter guide part includes: a first guide tube 310, a second guide tube 320, a third guide tube 330, a first filter tube 340, a second filter tube 350 and a third filter tube 360. The first guide tube 310, the second guide tube 320 and the third guide tube 330 are respectively surrounded by the outer side of the upper barrel body 110 along the circumference of the upper barrel body 110, and the first guide tube 310, the second guide tube 320 and the third guide tube 330 are arranged in parallel; a plurality of first filter tubes 340 are provided, and the plurality of first filter tubes 340 are respectively arranged between the first guide tube 310 and the outer side wall of the upper barrel body 110, one end of the first filter tube 340 is connected to the first guide tube 310, and the other end of the first filter tube 340 passes through the outer side wall of the upper barrel body 110 and is connected to the first cavity; a plurality of second filter tubes 350 are provided Dry, and several second filter tubes 350 are respectively arranged between the second guide tube 320 and the outer wall of the upper barrel body 110, one end of the second filter tube 350 is connected to the second guide tube 320, and the other end of the second filter tube 350 passes through the outer wall of the upper barrel body 110 and is connected to the first cavity; a plurality of third filter tubes 360 are provided, and several third filter tubes 360 are respectively arranged between the third guide tube 330 and the outer wall of the upper barrel body 110, one end of the third filter tube 360 ​​is connected to the third guide tube 330, and the other end of the third filter tube 360 ​​passes through the outer wall of the upper barrel body 110 and is connected to the first cavity.

[0056] Specifically, the multi-layer filter guide part is composed of a first guide tube 310, a second guide tube 320, a third guide tube 330, a first filter tube 340, a second filter tube 350 and a third filter tube 360. These guide tubes and filter tubes are respectively surrounded on the outside along the circumference of the upper barrel 110 and arranged in parallel. Secondly, the first filter tube 340 is arranged between the first guide tube 310 and the outer wall of the upper barrel 110, one end is connected to the first guide tube 310, and the other end passes through the outer wall of the upper barrel 110 and is connected to the first cavity. The second filter tube 350 and the third filter tube 360 ​​are arranged in a similar manner to the first filter tube 340, and are respectively arranged between the second guide tube 320 and the outer wall of the upper barrel 110, and the third guide tube 330 and the outer wall of the upper barrel 110, and are connected to the corresponding guide tube and the first cavity. The design principle of this multi-layer filter guide part is to gradually improve the filtering effect of the coal powder to be diverted by multi-stage filtering. The pulverized coal is gradually filtered by the filter tubes to remove impurities and particles when passing through the first guide tube 310, the second guide tube 320 and the third guide tube 330. The setting of each level of filter tubes can further improve the purity and quality of the pulverized coal, ensuring that the products after diversion meet the requirements of industrial production.

[0057] In some embodiments of the utility model, the first guide pipe 310, the second guide pipe 320 and the third guide pipe 330 are also respectively provided with a discharge pipe 370, one end of the discharge pipe 370 is connected to the guide pipe, and the other end of the discharge pipe 370 is connected to the storage box, and the discharge pipe 370 is used to discharge the guided coal powder to the storage box.

[0058] Specifically, the function of the guide pipe is to guide the flow of the coal powder to be diverted. The discharge pipe 370 is responsible for discharging the diverted coal powder from the guide pipe into the storage box. This setting effectively separates the filtered coal powder and the coal powder to be filtered, prevents the two from mixing, and ensures the normal operation of the diverter. Secondly, the design of the discharge pipe 370 makes the operation of the diverter more convenient. By connecting the discharge pipe 370 to the storage box, the filtered coal powder can be directly transported to the designated location without the need for additional conveying equipment. This can save manpower and time costs and improve production efficiency.

[0059] In some embodiments of the present invention, the filtration aperture of the first filter tube 340 is smaller than the filtration aperture of the second filter tube 350 , which is smaller than the filtration aperture of the third filter tube 360 ​​.

[0060] The shunt structure of a dual-adjustable shunt separator in the above-mentioned embodiments provides a sufficient accommodation space through the shunt barrel 100, manages and processes the flow of coal powder in an orderly manner, and ensures that it smoothly enters the subsequent processing stage. Secondly, the introduction of the hot air guide not only effectively reduces the humidity of the coal powder, thereby avoiding the problem of easy agglomeration of coal powder, but also enhances the fluidity of the coal powder inside the shunt barrel 100 through the blowing effect of the hot air, improves the fluidity and uniformity of the coal powder, and further optimizes the shunt effect. In addition, the establishment of the multi-layer filter guide provides an important filtering and guiding mechanism for the separation process. By setting the filter tube, impurities and bad particles in the coal powder can be effectively removed, the precision and accuracy of the shunt process are improved, and the quality and purity of the coal powder after separation are guaranteed. Finally, the setting of the support frame 400 not only provides a stable support for the shunt barrel 100, but also enhances the stability and reliability of the overall structure, which helps to ensure that the shunt can continue to operate stably and maintain a good working state, thereby improving production efficiency and product quality.

[0061] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
