In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0046] As described above, the material distribution device in the related art usually rotates the built-in distribution plate to distribute materials. This material distribution method has low precision and it is difficult to achieve precise feeding for downstream equipment. The present invention proposes a material distribution device. After preliminary material distribution by the distribution plate, a rotor is then applied for precise material distribution to achieve precise feeding for downstream equipment. The following will be specifically described in combination with embodiments and the accompanying drawings.

[0047] Refer to Figure 1 、 Figure 2 , the dashed lines in the figure represent the blocked components, and the dotted arrow represents the conveying direction of the material. The material distribution device of the first embodiment of the present invention includes a main body 100, a guiding valve plate 200, and a first conveying component 300. Among them, the main body 100 is used to provide a passage for the material to pass through. The guiding valve plate 200 can perform preliminary diversion of the material. The first conveying component 300 can quantitatively convey the material that has been preliminarily distributed by the guiding valve plate 200, so as to precisely control the supply amount to the downstream equipment.

[0048] The main body 100 includes a first distribution cylinder 110 and a second distribution cylinder 120. The first distribution cylinder 110 defines a first passage 111, a first discharge port 112, and a first feed port. The material can enter the first passage 111 through the first feed port and then be output from the first passage 111. The second distribution cylinder 120 defines a second passage 121, a second discharge port 122, and a second feed port. The material can enter the second passage 121 through the second feed port and then be output from the second discharge port 122. The first passage 111 is in communication with the second passage 121. In Figure 1 the illustrated embodiment, the second distribution cylinder 120 is vertically arranged, the second feed port is arranged at the top of the second distribution cylinder 120, the first distribution cylinder 110 is connected to one side (for example, the left side in the figure) of the second distribution cylinder 120, and is in communication with the second passage 121 through the first feed port. After the material enters the second passage 121 and is diverted by the guiding valve plate 200, it then enters the first passage 111 through the first feed port. In some other embodiments, refer to Figure 6, the main body 100 can also be provided with a main material cylinder 130. The main material cylinder 130 is vertically arranged and has a main feed inlet at the top. The first material distribution cylinder 110 and the second material distribution cylinder 120 are respectively connected to both sides of the main material cylinder 130. After the material enters the main material cylinder 130 and is split by the material guiding valve plate 200, it then enters the first channel 111 through the first feed inlet and / or enters the second channel 121 through the second feed inlet. In some embodiments, the interior of the main body 100 further includes a filler, and the filler is connected to the inner wall of the first material distribution cylinder 110, which can reduce the gap between the inner wall of the first material distribution cylinder 110 and the first conveying assembly 300, thereby reducing the material remaining in the gap. The filler can also be made of a heat-insulating material to adapt to the conveying of high-temperature materials.

[0049] The material guiding valve plate 200 is connected to the main body 100 and can rotate relative to the main body 100 to adjust the amount of material entering the first channel 111, so as to Figure 1 Taking the illustration as an example, the material guiding valve plate 200 is generally located at the connection of the first material distribution cylinder 110 and the second material distribution cylinder 120. Specifically, the material guiding valve plate 200 is rotationally connected to the first material distribution cylinder 110 or the second material distribution cylinder 120 through a first rotating shaft at its bottom end. The top end of the material guiding valve plate 200 is a free end. As the material guiding valve plate 200 swings, the amount of material entering the first channel 111 will increase or decrease. For example, when the material guiding valve plate 200 rotates Figure 1 in the counterclockwise direction in the illustration, the amount of material entering the first channel 111 decreases. When the material guiding valve plate 200 rotates Figure 1 in the clockwise direction in the illustration, the amount of material entering the first channel 111 increases. Taking Figure 6 the illustration as an example, the material guiding valve plate 200 is generally located between the first material distribution cylinder 110 and the second material distribution cylinder 120. Specifically, the material guiding valve plate 200 is rotationally connected to the main material cylinder 130 through a first rotating shaft at its bottom end. When the material guiding valve plate 200 rotates Figure 6 in the counterclockwise direction in the illustration, the amount of material entering the first channel 111 decreases. When the material guiding valve plate 200 rotates Figure 6 in the clockwise direction in the illustration, the amount of material entering the first channel 111 increases. Based on the above, the amount of material entering the first channel 111 can be adjusted by the swing of the material guiding valve plate 200. It can be understood that since the total amount of material entering the second material distribution cylinder 120 or the main material cylinder 130 per unit time is constant, adjusting the amount of material entering the first channel 111 also means adjusting the amount of material entering the second channel 121.

[0050] The material guiding valve plate 200 is driven by a driving device such as a motor.

[0051] The first conveying assembly 300 includes a first rotor 310. The first rotor 310 is located in the first channel 111 and can rotate relative to the first dosing cylinder 110 to convey the material in the first channel 111 to the first discharge port 112. Specifically, referring to Figure 2 , the first rotor 310 includes a rotating shaft 311 and a plurality of blades 312. The first rotor 310 is rotatably connected to the first dosing cylinder 110 through the rotating shaft 311. The plurality of blades 312 are circumferentially distributed along the rotating shaft 311. A storage space is formed between adjacent blades 213. As the first rotor 310 rotates, the material in the storage space is transferred to the first discharge port 112. Since the volume of each storage space is fixed, the amount of material conveyed when the first rotor 310 rotates one week is also relatively fixed. The faster the rotation speed of the first rotor 310, the more material is conveyed; the slower the rotation speed, the less material is conveyed. In other words, the material conveying amount of the first rotor 310 is related to the rotation speed of the rotor. By adjusting the rotation speed of the first rotor 310, the material conveying speed in the first channel 111 can be adjusted. In this embodiment, the material is divided by the guiding valve plate 200, so that part or all of the material enters the first channel 111, and then is precisely conveyed by the first conveying assembly 300, so that at least the amount of material output from the first channel 111 can be precisely controlled.

[0052] Specifically, the rotating shaft 311 is connected to a driving device such as a motor, and the rotation speed of the first rotor 310 can be controlled by adjusting the motor.

[0053] On the basis of the first embodiment, in some embodiments, referring to Figure 3 , the first conveying assembly 300 further includes a second rotor 320. The second rotor 320 is also located in the first channel 111 and is arranged in parallel with the first rotor 310. For example, it is arranged in parallel along the width direction of the first channel 111. The second rotor 320 can also rotate relative to the first dosing cylinder 110 to convey the material in the first channel 111 to the first discharge port 112, and the rotation directions of the first rotor 310 and the second rotor 320 are opposite, so as to jointly control the amount of material output from the first channel 111. For example, the first rotor 310 rotates in the Figure 3 clockwise direction, and the second rotor 320 rotates in the Figure 3 counterclockwise direction, and the material can be conveyed from between the first rotor 310 and the second rotor 320 to the first discharge port 112.

[0054] When the first conveying assembly 300 further includes a second rotor 320, in some embodiments, the first rotor 310 and the second rotor 320 are driven by the same driving device, thus saving costs and helping to achieve synchronous rotation of the first rotor 310 and the second rotor 320. For example, the driving device drives the first rotor 310 and the second rotor 320 to rotate respectively through a transmission mechanism such as a gear set or a transmission belt and a transmission wheel.

[0055] When the first conveying assembly 300 further includes a second rotor 320, in some embodiments, both the first rotor 310 and the second rotor 320 include a rotating shaft 311 and a plurality of blades 312. Taking the first rotor 310 as an example, with reference to Figure 3 , the first rotor 310 includes a rotating shaft 311 and a plurality of blades 312. The first rotor 310 is rotatably connected to the first material distribution cylinder 110 through the rotating shaft 311, and the blades 312 are fixedly connected to the rotating shaft 311. Specifically, the blades 312 can be fixed to the rotating shaft 311 through processes such as welding, or can be integrally formed with the rotating shaft 311 through processes such as sintering. The plurality of blades 312 are circumferentially distributed along the rotating shaft 311. In some specific embodiments, the plurality of blades 312 are evenly circumferentially distributed along the rotating shaft 311, so that the volumes of the respective storage spaces are equal, which further helps to adjust the conveying amount of the material by controlling the rotation speed of the first rotor 310. Taking Figure 3 as an example, the first rotor 310 includes four blades 312. In other embodiments, the first rotor 310 can also include other numbers of blades, such as two, three, five, etc.

[0056] When the material distribution device is connected to the downstream decomposition furnace, high-temperature airflows that are roughly opposite to the material transportation direction may be input from the decomposition furnace into the material distribution device. On the one hand, these airflows will affect the heat carried away from the decomposition furnace and increase the heat loss of the decomposition furnace. On the other hand, they will also hinder the falling of the material. Based on this, in this embodiment, a reference plane perpendicular to the axis of the first channel 111 is established, and the projections of the blades 312 of the first rotor 310 and the projections of the blades 312 of the second rotor 320 partially overlap. In other words, in the direction of the connection line of the axis centers of the rotating shafts of the first rotor 310 and the second rotor 320, the distance between the rotating shafts of the first rotor 310 and the second rotor 320 is less than the sum of the radii of the first rotor 310 and the second rotor 320. Specifically, with reference to Figure 3 , the blades 312 of the second rotor 320 extend into at least the spaces between the adjacent blades 312 of the first rotor 310, so that the blades 312 of the first rotor 310 and the blades 312 of the second rotor 320 mesh with each other. In this way, the blades 312 of the first rotor 310 and the second rotor 320 can play a certain sealing role to block the upward flowing airflows. On the one hand, it can reduce the heat loss of the decomposition furnace, and on the other hand, it is also beneficial to the falling of the material.

[0057] In this embodiment, the first rotor 310 and the second rotor 320 can be driven by the same driving device, which is convenient for controlling the synchronous rotation of the first rotor 310 and the second rotor 320 and ensuring the meshing of the two rotor blades.

[0058] When the first conveying assembly 300 further includes the second rotor 320, in some embodiments, the material guiding valve plate 200 includes a substrate 210 and a plurality of guiding portions 220. Refer to Figure 1 And Figure 4 , the substrate 210 has a receiving surface 211 for receiving materials. For example, the substrate 210 is a flat plate mechanism, and the upper surface of the substrate 210 is the receiving surface 211. The materials will first fall onto the receiving surface 211 and then slide along the receiving surface 211 into the first channel 111.

[0059] The plurality of guiding portions 220 are arranged on the receiving surface and are used to guide the materials to the area between the first rotor 310 and the second rotor 320, facilitating the entry of the materials into the storage spaces of the first rotor 310 and the second rotor 320. In addition, the guiding portions 220 can also increase the strength of the material guiding valve plate 200. Specifically, one end of the guiding portion 220 points to the area between the first rotor 310 and the second rotor 320, and the other end extends in a direction away from the first conveying assembly 300. A material guiding channel is formed between adjacent guiding portions 220. In some specific embodiments, at least some of the guiding portions 220 are inclined such that the width of at least some of the material guiding channels gradually decreases in the direction pointing to the first conveying assembly 300.

[0060] The guiding portion 220 can be fixedly connected to the substrate 210 by processes such as welding, or can be integrally connected to the substrate 210.

[0061] On the basis of the first embodiment, in some embodiments, refer to Figure 1 , the first material distribution cylinder 110 includes a first connection section 113 and a second connection section 114. The first connection section 113 is connected to the second material distribution cylinder 120, the second connection section 114 is connected to the first connection section 113, and the end of the second connection section 114 away from the first connection section 113 has a first discharge port 112. In other words, the materials will first enter the first connection section 113, then enter the second connection section 114 from the first connection section 113, and finally be output from the second connection section 114.

[0062] In this embodiment, the first connection section 113 is horizontally arranged, and the first rotor 310 is located in the first channel 111 of the first connection section 113. In this way, after the materials enter the first connection section 113, they will be cached in the first connection section 113 and will be transported by the first rotor 310 instead of automatically sliding down due to gravity, facilitating precise feeding.

[0063] In this embodiment, the second connecting section 114 extends downward. The so-called downward extension includes both the scheme of extending vertically downward and the scheme of extending obliquely downward (for example Figure 1 as shown), which facilitates the automatic sliding of materials into downstream equipment such as a decomposition furnace under the action of gravity.

[0064] Based on the first embodiment, in some embodiments, referring to Figure 2 , Figure 3 and Figure 5 , the first conveying assembly 300 further includes a receiving plate 330 located in the first channel 111. The first rotor 310 is located above the receiving plate 330, and the bottom end of the material guiding valve plate 200 extends above the receiving plate 330. Materials can slide from the material guiding valve plate 200 to the receiving plate 330, and then be conveyed by the first rotor 310. The projection of the first rotor 310 on the receiving plate 330 is located within the receiving plate 330. For example, the receiving plate 330 can be a flat plate structure that is generally circular, and the diameter of the receiving plate 330 is greater than the diameter of the first rotor 310. It should be noted that when the first conveying assembly 300 further includes a second rotor 320, the projections of the first rotor 310 and the second rotor 320 on the receiving plate 330 are both located within the receiving plate 330.

[0065] In this embodiment, the receiving plate 330 is provided with a material dropping port 331. The first rotor 310 can rotate relative to the main body 100 to transport materials to the material dropping port 331, and the materials can drop downward through the material dropping port 331, for example, into the aforementioned second connecting section 114. Taking Figure 2 as an example, the material dropping port 331 and the material guiding valve plate 200 are respectively located on opposite sides of the first rotor 310.

[0066] It should be noted that when the first conveying assembly 300 further includes a second rotor 320, referring to Figure 3 , the material dropping port 331 is arranged between the first rotor 310 and the second rotor 320.

[0067] Based on the first embodiment, in some embodiments, referring to Figure 1 , the second material distribution cylinder 120 is arranged vertically. The second feed inlet is arranged at the top of the second material distribution cylinder 120. The first material distribution cylinder 110 is connected to one side (for example, the left side in the figure) of the second material distribution cylinder 120 and is communicated with the second channel 121 through the first feed inlet. Materials from upstream equipment will first enter the second channel 121, and then enter the first channel 111 through the first feed inlet. The material guiding valve plate 200 can rotate relative to the main body 100 to adjust the amount of materials entering the first channel 111 from the second channel 121. Specifically, the bottom end of the material guiding valve plate 200 is generally arranged at the connection between the first material distribution cylinder 110 and the second material distribution cylinder 120, and the whole material guiding valve plate 200 can swing around the bottom rotating shaft.

[0068] In some other embodiments, with reference to Figure 6 , the main body 100 further includes a main material cylinder 130. The main material cylinder 130 is vertically arranged and has a main feed port at the top. The first material distribution cylinder 110 and the second material distribution cylinder 120 are respectively connected to both sides of the main material cylinder 130. The materials from the upstream equipment will first enter the main material cylinder 130, and then enter the first channel 111 and the second channel 121 through the first feed port and the second feed port respectively. The material guiding valve plate 200 can rotate relative to the main body 100 to adjust the amount of materials entering the first channel 111 and the second channel 121 from the main material cylinder 130.

[0069] In this embodiment, the material distribution device further includes a second conveying component 400. The second conveying component 400 includes a third rotor 410. The third rotor 410 is located in the second channel 121 and can rotate relative to the second material distribution cylinder 120 to convey the materials in the second channel 121 to the second discharge port 122. Specifically, with reference to Figure 6 , similar to the first rotor 310, the third rotor 410 also includes a rotating shaft 311 and a plurality of blades 312. The third rotor 410 is rotationally connected to the second material distribution cylinder 120 through the rotating shaft 311. The plurality of blades 312 are circumferentially distributed along the rotating shaft 311. A material storage space is formed between adjacent blades 213. As the third rotor 410 rotates, the materials in the material storage space are transferred to the second discharge port 122. Since the volume of each material storage space is fixed, the amount of materials conveyed when the third rotor 410 rotates one week is also relatively fixed. The faster the rotation speed of the third rotor 410, the more materials are conveyed; the slower the rotation speed, the less materials are conveyed. In other words, the material conveying amount of the third rotor 410 is related to the rotation speed of the rotor. By adjusting the rotation speed of the third rotor 410, the material conveying speed in the second channel 121 can be adjusted. In this embodiment, the material guiding valve plate 200 is used to adjust the amount of materials entering the first channel 111 and the second channel 121 from the main material cylinder 130, and then precise conveying is carried out through the first conveying component 300 and the second conveying component 400, so as to accurately control the amount of materials output from the first channel 111 and the second channel 121.

[0070] When the material distribution device further includes a second conveying component 400, in some specific embodiments, the second conveying component 400 further includes a fourth rotor. The fourth rotor is also located in the second channel 121 and is arranged in parallel with the third rotor 410. The fourth rotor can also rotate relative to the second material distribution cylinder 120 to convey the materials in the second channel 121 to the second discharge port 122, and the rotation directions of the third rotor 410 and the fourth rotor are opposite, so as to jointly control the amount of materials output from the second channel 121.

[0071] When the second conveying assembly 400 further includes a fourth rotor, in some embodiments, the third rotor 410 and the fourth rotor are driven by the same driving device, thereby saving costs and facilitating the synchronous rotation of the third rotor 410 and the fourth rotor. For example, the driving device drives the third rotor 410 and the fourth rotor to rotate respectively through a transmission mechanism such as a gear set or a transmission belt and a transmission wheel.

[0072] Based on the first embodiment, in some embodiments, the material guiding valve plate 200 is further configured to be able to rotate the main body 100 to a first position to close the first channel 111 and open the second channel 121, so as to Figure 1 Taking the shown as an example, when the material guiding valve plate 200 rotates leftward to the first position, it is in a vertical state. The first channel 111 is closed and the second channel 121 is opened. The material falls downward under the action of gravity, so as to Figure 6 Taking the shown as an example, when the material guiding valve plate 200 rotates leftward to the limit position, the first channel 111 is closed and the second channel 121 is opened, and all the material enters the second channel 121.

[0073] Based on the first embodiment, in some embodiments, the material guiding valve plate 200 is further configured to be able to rotate the main body 100 to a second position to open the first channel 111 and close the second channel 121, so as to Figure 1 Taking the shown as an example, when the material guiding valve plate 200 rotates rightward to the first position, it is in a horizontal state. The first channel 111 is opened and the second channel 121 is closed, and all the material enters the first channel 111, so as to Figure 6 Taking the shown as an example, when the material guiding valve plate 200 rotates rightward to the limit position, the first channel 111 is opened and the second channel 121 is closed, and all the material enters the first channel 111.

[0074] It can be understood that when the material guiding valve plate 200 is between the first position and the second position, both the first channel 111 and the second channel 121 are in an open state, and the material can enter the first channel 111 and the second channel 121 simultaneously. Moreover, according to the different inclination angles of the material guiding valve plate 200, the amounts of the material entering the first channel 111 and the second channel 121 will also change.

[0075] The second embodiment of the present invention also provides a cement production system, including a decomposition furnace, a controller and the material distributing device in the foregoing embodiment. Among them, the first material distributing cylinder 110 is communicated with a first part of the decomposition furnace, and the second material distributing cylinder 120 is communicated with a second part of the decomposition furnace different from the first part. It should be noted that when describing that the material distributing cylinder is communicated with the decomposition furnace, it includes both the scheme that the material distributing cylinder is directly communicated with the decomposition furnace and the scheme that the material distributing cylinder is indirectly communicated with the decomposition furnace through other pipelines.

[0076] In this embodiment, the controller is configured to adjust the rotational speed of the first rotor 310 based on the temperature of the first part. Specifically, the temperature of the material output from the feeding device is lower than the temperature in the decomposition furnace. If the low-temperature material enters the decomposition furnace, it will reduce the temperature of the local area. Based on this, when the temperature of the first part is low and the temperature needs to be increased, the controller reduces the rotational speed of the first rotor 310. When the temperature of the first part is high and the temperature needs to be reduced, the controller increases the rotational speed of the first rotor 310.

[0077] It should be noted that the first part and the second part may be staggered in the vertical direction or staggered in the circumferential direction of the decomposition furnace.

[0078] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
