The tamping coke oven coking has wider coal source than the top loading coke oven coking because the tamping coke oven coking can be more blended with high volatile low caking coal or non-caking coal. With the increasing shortage of coking coal resources and the requirement of coking plants for improving production flexibility, the market demand of top-loading tamping integrated coke ovens or top-loading coke ovens to top-loading tamping integrated coke ovens is continuously increasing. In the top loading and tamping integrated coke oven coal preparation process, how to realize coal feeding switching of charging coal in two different production modes of top loading and tamping is a technical key point.
At present, the coal feeding and switching of the domestic top-loading tamping integrated coke oven is realized by adopting a mode of switching the coal outlet of the top-loading coal tower. As in chinese patent publication No. CN103992803a, "a coke oven apparatus capable of producing both stamp-charged coke and top-charged coke": two funnel groups are arranged below a top coal charging tower and correspond to top coking coal charging and tamping coking coal charging respectively, and a fixed belt conveyor is connected with the tamping coking funnel groups of the top coal charging tower and a side tamping coal charging tower; chinese patent publication No. CN107298981a discloses a "7.3 m top-loading tamping dual-purpose coke oven production process": the top-loading coal feeding port and the tamping coal feeding port are arranged below the top-loading coal tower, and the fixed belt conveyor is connected with the tamping coal feeding port of the top-loading coal tower and the tamping coal tower, so that the coal feeding switching of the top-loading tamping two kinds of charging coal is realized. The two technical schemes can realize the coal feeding switching of two kinds of top loading tamping charging coals, but have the following defects:
(1) When the top loading coking or the tamping coking is carried out, in the two technical schemes, the two coal outlet devices are in the state that one coal outlet device of the coal tower is in production and the other coal outlet device is idle, so that the utilization rate of the coal outlet device of the top loading coal tower is greatly reduced.
(2) The raw material coal is accumulated in the coal hopper above the idle coal outlet, so that dead coal is formed after hardening, the effective capacity of the coal tower is reduced, and the investment is increased to increase the effective capacity of the coal tower; in addition, the switching of the coking mode of the coke oven is limited by factors such as coal types, markets and the like, the period is long (from months to years), and the dead coal in the coal hopper is easy to produce spontaneous combustion and even explosion for a long time, so that the potential safety hazard is greatly increased.
(3) The fixed belt conveyor is used for connecting the coal outlet of the top coal charging tower and the tamping coal tower, so that the height of the top coal charging tower is at least required to be raised by 3-4 m to simultaneously meet the coal charging space requirements of the top coal charging vehicle and the fixed belt conveyor, and the investment of the coal tower and a coal conveying system in front of the coal tower is increased.

The buried scraper type coal feeding and distributing device for the top-loading tamping integrated coke oven according to claim 1, wherein the running mechanism consists of a hanging rail running mechanism and a running rail running mechanism; the lifting rail running mechanism comprises 1 to more groups of lifting rail running wheel groups, each group of lifting rail running wheel groups consists of a plurality of lifting rail running wheels and a lifting rail wheel frame, wherein the lifting rail wheel frame is fixedly connected with a rack of the movable buried scraper conveyor through a lifting rail connecting piece; the rail running mechanism comprises a plurality of rail running wheels and a running driving device, and the rail running wheels are arranged at the bottom of the frame; when the movable buried scraper conveyor is above the tamping coal bucket, the movable buried scraper conveyor moves along the track through the track traveling wheel under the drive of the track driving device; one end of the movable buried scraper conveyor moves below the coal tower and simultaneously moves along the travelling rail and the hanging rail.
4. The buried scraper type coal feeding and distributing device for the top-loading tamping integrated coke oven according to claim 1, wherein the plurality of feeding ports are arranged in one-to-one correspondence with the coal lower ports of the coal tower.
5. The embedded scraper type coal feeding and distributing device for the top-loading tamping integrated coke oven according to claim 1, wherein the embedded scraper type coal feeding and distributing device is further provided with a running limiting device, and the running limiting device is connected with a running driving device of the movable embedded scraper conveyor through a control system, so that the movable embedded scraper conveyor can automatically stay at the first station or the second station after moving.
6. The working method of the buried scraper type coal feeding and distributing device for the top-loading and tamping integrated coke oven, according to claim 1, is characterized in that coal feeding switching during top-loading and tamping coal-loading coking is realized by reciprocating along a running track by a movable buried scraper conveyor: the specific process is as follows:
1) When the coke oven adopts a tamping coking mode, the movable buried scraper conveyor moves to a position between a coal inlet of the coal tower and a coal feeding and distributing port of the tamping coal bucket and stays at a first station; starting a chain driving device on the movable buried scraper conveyor, and driving the buried scraper conveyor to move by a scraper chain; opening a coal tower coal outlet, discharging the charging coal from the coal tower coal outlet to a closed box body of a movable buried scraper conveyor, conveying the charging coal to the position above a coal feeding distributing opening of a tamping coal bucket through a conveying buried scraper, and charging the coal into the tamping coal bucket through a discharging opening; when coal is loaded, the gate opening and closing control system controls each discharging gate to be opened and closed according to a set sequence, so that uniform distribution is realized;
2) When the coke oven adopts a top-loading coking mode, the movable buried scraper conveyor moves away from the lower part of the coal tower, integrally moves to the upper part of the tamping coal bucket, and the top-loading coal charging car moves to the lower part of the coal tower and charges coal into the top-loading coal charging car through a coal outlet of the coal tower.
