Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0041] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0042] Figure 1 A coal tower material distribution system 10 according to an embodiment of the present application is combined with Figure 1 The coal tower material distribution system 10 includes a main chute 100, a material distribution machine 200, a coal tower 300, an auxiliary chute 400 and a switch assembly 500.

[0043] In the embodiment of the present application, the distribution machine 200 is arranged between the main chute 100 and the coal tower 300. The distribution machine 200 is used to receive the coal discharged from the discharge port of the main chute 100, and to distribute the coal to the coal tower 300. The inlet of the auxiliary chute 400 is connected to the main chute 100, and the discharge port of the auxiliary chute 400 is corresponding to the coal tower 300, and is used to distribute the coal to the coal tower 300. The switch assembly 500 is arranged at the connection between the main chute 100 and the auxiliary chute 400, and is used to selectively close one of the main chute 100 and the auxiliary chute 400.

[0044] Specifically, in the coal coking production, the previous section system of the coal tower distribution system 10 is the coal preparation system. The qualified coal prepared in the coal preparation system is stored in the coal blending workshop of the coal preparation system. The qualified coal prepared in the coal blending workshop is transported to the main chute 100 through the inlet of the main chute 100. In the coal tower distribution system 10, the coal in the main chute 100 is transported to the distribution machine 200 through the outlet of the main chute 100, and then the distribution machine 200 distributes the coal to the coal tower 300 to meet the production needs of the coke oven. However, once the distribution machine 200 fails during the production process, it often takes a long time to repair the distribution machine 200, which causes the coke oven to stop production for a long time, resulting in discontinuous and unstable production, which affects the production quality and progress.

[0045] By connecting the auxiliary chute 400 between the main chute 100 and the coal tower 300, the inlet of the auxiliary chute 400 is connected to the inside of the main chute 100, the outlet of the auxiliary chute 400 is set corresponding to the inlet of the coal tower 300, and the switch assembly 500 is set at the connection between the main chute 100 and the auxiliary chute 400. When the material distribution machine 200 fails, the switch assembly 500 is operated to close the main chute 100 and open the auxiliary chute 400. At this time, the inlet of the main chute 100 is separated from the outlet of the main chute 100, and the inlet of the main chute 100 is connected with the outlet of the auxiliary chute 400, so that the coal in the main chute 100 is no longer transported to the material distribution machine 200 through the outlet of the main chute 100, but the coal in the main chute 100 is transported to the coal tower 300 through the auxiliary chute 400. After the maintenance of the material distributor 200 is completed, the switch assembly 500 is operated to close the auxiliary chute 400 and open the main chute 100. At this time, the inlet of the main chute 100 is connected with the outlet of the main chute 100, and the inlet of the main chute 100 is separated from the outlet of the auxiliary chute 400, so that the coal in the main chute 100 is no longer transported to the coal tower 300 through the auxiliary chute 400, but is restored to be transported to the material distributor 200 through the outlet of the main chute 100, and the material is continuously distributed to the coal tower 300 through the material distributor 200. In this way, the situation of long-term shutdown of the coke oven is reduced, the continuity and stability of production are guaranteed, and the production quality and progress are improved.

[0046] It should be noted that in the coal tower distribution system 10, the distribution machine 200 is used to distribute the coal into the coal tower 300 to improve the uniformity of the coal in the coal tower 300, thereby improving the production quality of the coke oven. Therefore, when the distribution machine 200 fails and is repaired, the auxiliary chute 400 is only used as a temporary conveying device. After the maintenance of the distribution machine 200 is completed, the main chute 100 needs to be restored as soon as possible to convey the coal.

[0047] In some embodiments, the switch assembly 500 includes a first switch element 510 and a second switch element 520, wherein the first switch element 510 can be opened and closed in the main chute 100, and the first switch element 510 is arranged between the inlet of the auxiliary chute 400 and the outlet of the main chute 100, and the second switch element 520 can be opened and closed in the auxiliary chute 400.

[0048] When the material placing machine 200 fails, the first switch 510 is operated to close the main chute 100, and the second switch 520 is operated to open the auxiliary chute 400, so that the inlet of the main chute 100 is isolated from the outlet of the main chute 100, and the inlet of the main chute 100 is connected with the outlet of the auxiliary chute 400. After the maintenance of the material placing machine 200 is completed, the first switch 510 is operated to open the main chute 100, and the second switch 520 is operated to close the auxiliary chute 400, so that the inlet of the main chute 100 is connected with the outlet of the main chute 100, and the inlet of the main chute 100 is isolated from the outlet of the auxiliary chute 400.

[0049] The auxiliary chute 400 is connected to the main chute 100, and the inlet of the auxiliary chute 400 is connected to the interior of the main chute 100. The first switch member 510 is set between the inlet of the auxiliary chute 400 and the outlet of the main chute 100, so that when the first switch member 510 closes the main chute 100 and the second switch member 520 opens the auxiliary chute 400, the coal material entering the interior of the main chute 100 from the inlet of the main chute 100 cannot be discharged from the outlet of the main chute 100, but can only enter the interior of the auxiliary chute 400 from the inlet of the auxiliary chute 400, and finally be discharged from the outlet of the auxiliary chute 400.

[0050] It should be noted that the first switch member 510 and the second switch member 520 are both arranged at the connection between the main chute 100 and the auxiliary chute 400 to avoid excessive coal from accumulating on the first switch member 510 and the second switch member 520 when the first switch member 510 and the second switch member 520 are in a closed state, thereby ensuring the use effect of the first switch member 510 and the second switch member 520.

[0051] In some embodiments, the first switch 510 includes a first flap 511 and a second flap 512, the first flap 511 and the second flap 512 are arranged opposite to each other, and the opposite ends of the first flap 511 and the second flap 512 are both rotatably connected to the inner wall of the main chute 100. The second switch 520 is a plug 521, the auxiliary chute 400 is provided with a plug hole, and the plug 521 is movably inserted into the plug hole of the auxiliary chute 400 and extends into the auxiliary chute 400. When the first flap 511 and the second flap 512 are rotated to a position where the opposite ends are in contact, the first switch 510 closes the main chute 100; when the first flap 511 and the second flap 512 are rotated to a position where the opposite ends are not in contact, the first switch 510 opens the main chute 100.

[0052] The first switch 510 is used to open or close the main chute 100. The first switch 510 includes a first flap 511 and a second flap 512. The first switch 510 opens and closes the main chute 100 by rotating the first flap 511 and the second flap 512. When the first switch 510 closes the main chute 100, the first flap 511 and the second flap 512 rotate to a position where opposite ends contact. At this time, the first flap 511 contacts the opposite end of the second flap 512, and the distance between the first flap 511 and the second flap 512 is the minimum value, and the inlet and outlet of the main chute 100 are separated. When the second switch 520 opens the main chute 100, the first flap 511 and the second flap 512 rotate to a position where the opposite ends are not in contact. At this time, the opposite ends of the first flap 511 and the second flap 512 are not in contact, and the distance between the first flap 511 and the second flap 512 is greater than the minimum value. The inlet and outlet of the main chute 100 are connected, so that the coal can pass between the first flap 511 and the second flap 512 and be output from the outlet of the main chute 100.

[0053] In order to realize the arrangement of the first flap 511 and the second flap 512 in the main chute 100, the inner wall of the main chute 100 is relatively provided with two overlapping parts 110, and the two overlapping parts 110 are respectively hingedly connected to the ends of the first flap 511 and the second flap 512 opposite to each other, so as to ensure the rotation effect of the first flap 511 and the second flap 512. In practice, in order to realize the rotation of the first flap 511 and the second flap 512, a rotation hole is usually provided on the main chute 100, and an operating rod is respectively provided on the first flap 511 and the second flap 512. The operating rod on the first flap 511 and the second flap 512 is coaxially arranged with the rotation axis, so that the operating rod is inserted into the rotation hole, so as to realize the rotation of the first flap 511 and the second flap 512 by controlling the movement of the operating rod. When the first flap 511 and the second flap 512 are rotated to the required position, the operating rod is fixed, so as to realize the fixing of the first flap 511 and the second flap 512.

[0054] The second switch 520 is used to open or close the auxiliary chute 400. The second switch 520 is set as a plug plate 521. The plug plate 521 is movably inserted into the plug hole of the auxiliary chute 400 and extends into the auxiliary chute 400, so that the second switch 520 can open and close the auxiliary chute 400. When the second switch 520 closes the auxiliary chute 400, the plug plate 521 is completely inserted into the auxiliary chute 400 to separate the inlet and outlet of the auxiliary chute 400. When the second switch 520 opens the auxiliary chute 400, the plug plate 521 is not completely inserted into the auxiliary chute 400 to connect the inlet and outlet of the auxiliary chute 400.

[0055] Of course, the first switch 510 may also be provided in the form of a plug 521. Similarly, the second switch 520 may also be provided in the form of a first flap 511 and a second flap 512. The embodiment of the present application does not limit this. The coal tower material distribution system 10 proposed in the embodiment of the present application is an improvement on the original coal tower material distribution system. The cross-sectional area of ​​the auxiliary chute 400 is smaller than that of the main chute 100. Therefore, the auxiliary chute 400 is more suitable for providing the plug 521. The main chute 100 has a larger cross-sectional area and is not suitable for providing the plug 521. Therefore, the first flap 511 and the second flap 512 are provided.

[0056] In some embodiments, when the first switch 510 closes the main chute 100, the first flap 511 and the second flap 512 are tilted toward the auxiliary chute 400. When the first switch 510 closes the main chute 100, the first flap 511 and the second flap 512 rotate to a position where the opposite ends are in contact, and the first flap 511 and the second flap 512 are usually flush at this time, and the first flap 511 and the second flap 512 are tilted toward the auxiliary chute 400, and the first flap 511 and the second flap 512 and the auxiliary chute 400 are usually set at the same tilt angle, and the first switch 510 is set between the inlet of the auxiliary chute 400 and the outlet of the main chute 100, so that the coal can be introduced into the inlet of the auxiliary chute 400 through the first switch 510.

[0057] In some embodiments, the switch assembly 500 includes a rotating plate, which is disposed at the connection position between the auxiliary chute 400 and the main chute 100, and the rotating plate is connected to the connection position between the auxiliary chute 400 and the main chute 100, which is close to the discharge port of the main chute 100. When the rotating plate rotates to a position to close the main chute 100, the switch assembly 500 closes the main chute 100 and opens the auxiliary chute 400; when the rotating plate rotates to a position to close the auxiliary chute 400, the switch assembly 500 opens the main chute 100 and closes the auxiliary chute 400.

[0058] By setting a rotating plate at the connection position between the auxiliary chute 400 and the main chute 100, the switch assembly 500 can selectively close one of the main chute 100 and the auxiliary chute 400. And the rotating plate is connected to the side of the connection position close to the discharge port of the main chute 100, so that when the rotating plate is rotated to the position of closing the main chute 100, the rotating plate is located between the feed port of the auxiliary chute 400 and the discharge port of the main chute 100.

[0059] It should be noted that the setting of the rotating plate needs to be realized, and the cross section of the main chute 100 is usually required to be the same as the cross section of the auxiliary chute 400. In addition, the setting method for realizing the operation of the first flap 511 and the second flap 512 can be adopted to set the rotating plate to realize the rotation operation of the rotating plate.

[0060] In some embodiments, when the rotating plate rotates to a position to close the main chute 100 , the rotating plate tilts toward the auxiliary chute 400 ; when the rotating plate rotates to a position to close the auxiliary chute 400 , the rotating plate is flush with the inner wall of the main chute 100 .

[0061] On the one hand, when the rotating plate rotates to the position of closing the main chute 100, the rotating plate is arranged between the inlet of the auxiliary chute 400 and the outlet of the main chute 100, so that the rotating plate is inclined toward the auxiliary chute 400. The rotating plate and the auxiliary chute 400 are usually arranged at the same inclination angle, and the coal can be introduced into the inlet of the auxiliary chute 400 through the rotating plate. On the other hand, when the rotating plate rotates to the position of closing the auxiliary chute 400, the rotating plate needs to close the auxiliary chute 400 without hindering the transportation of coal in the main chute 100, so the rotating plate is arranged to be flush with the inner wall of the main chute 100.

[0062] In some embodiments, the coal tower 300 has a plurality of coal bins 310, and the discharging end of the material distributor 200 can be selectively arranged corresponding to one of the plurality of coal bins 310. A plurality of auxiliary chutes 400 are provided, and the plurality of auxiliary chutes 400 are arranged corresponding to the plurality of coal bins 310 one by one.

[0063] The coal tower 300 has a plurality of coal bins 310. The coal outputted from the main chute 100 can be selectively transported to different coal bins 310 of the coal tower 300 by the discharging end of the distribution machine 200, thereby improving the uniformity of distribution. When the distribution machine 200 fails and needs to be repaired, one of the plurality of auxiliary chutes 400 can be selectively opened to achieve the same uniform distribution effect.

[0064] However, in practice, usually only one auxiliary chute 400 is required to be provided, and the auxiliary chute 400 is connected between the main chute 100 and a coal bunker 310 of the coal tower 300, so as to avoid increasing excessive production costs while ensuring production.

[0065] In some embodiments, the coal tower distribution system 10 is fixedly installed on the coking platform 20, and the main chute 100 is installed through the floor 21 of the coking platform 20 and is fixedly connected to the floor 21. The coal tower distribution system 10 also includes a hanging member 600, and the auxiliary chute 400 is arranged below the floor 21, and the hanging member 600 is connected between the floor 21 and the auxiliary chute 400.

[0066] The coking platform 20 provides an installation foundation for the coal tower material distribution system 10. The main chute 100 is fixed on a floor 21 of the coking platform 20. The material distribution machine 200 and the coal tower 300 are arranged below the floor 21 of the floor. The main chute 100 passes through the floor 21 and is arranged corresponding to the material distribution machine 200. The auxiliary chute 400 is connected to the main chute 100 at a position below the floor 21 of the floor. In order to further fix the auxiliary chute 400, the suspension member 600 is connected between the floor 21 and the auxiliary chute 400 to improve the fixing effect of the auxiliary chute 400. The suspension member 600 can be a sling, a suspension rod screw (screwed with the floor 21 to facilitate distance adjustment), etc., and the embodiment of the present application does not limit this.

[0067] In some embodiments, the auxiliary chute 400 is provided with a lifting ring 420, and the lifting member 600 is connected to the lifting ring 420. The lifting ring 420 facilitates the connection between the auxiliary chute 400 and the lifting member 600.

[0068] In some embodiments, the auxiliary chute 400 includes an inlet section 430, a connection section 440, and a discharge section 450 connected in sequence, the inlet section 430 is connected to the main chute 100, and the connection section 440 and the discharge section 450 are respectively provided with a lifting ring 420. By arranging the auxiliary chute 400 in sections, it is convenient to install the auxiliary chute 400 in the coal tower distribution system 10.
