Description

TECHNICAL FIELD

[0003] The main function of the coal charging car is to load the coal cake into the carbonization chamber of the coke oven in cooperation with the stamping machine, the feeder, and the smoke guide car. At present, the original design of the coal charging car is that the coal cake is sent into the carbonization chamber by the coal supporting bottom plate and the rear baffle during the coal charging process. A 60x60mm slot hole is opened in the movable wall of the coal box device close to the front baffle, and the hook head of the locking hook is extended from the slot hole to lock the rear baffle, so that the locking device locks the rear baffle of the coal charging car during the retraction of the coal supporting bottom plate, and the coal cake is left in the carbonization chamber. This design solves the problem that the rear baffle equipment locking can send the coal cake into the carbonization chamber. However, in the actual operation process of the equipment, there is a large amount of coal leakage or slot hole blockage in the locking hook slot hole. The coal powder falls from the slot hole to the coke oven platform and the machine side rail foundation, and a large amount of coal powder accumulates on the equipment frame. When the wind blows, the pulverized coal scatters everywhere, causing serious dust emission on the coke oven machine side, corroding the equipment frame, polluting the equipment such as the speed reducer, and causing a lot of work and environmental pollution to the post personnel.

[0030] The coal loading car is one of the main mechanical equipment used in the side loading stamping coke oven of the coking plant, which runs on the side of the coke oven machine, and mainly cooperates with the stamping machine, the feeder and the smoke guide car to load the coal cake into the carbonization chamber of the coke oven. The coal loading car mainly comprises a running device, a front baffle device, a rear baffle device, a coal box device, a first locking mechanism, a coal loading device, a coal cake flattening mechanism, a residual coal recovery device and a dust removal device.

[0031] The main function of the coal loading car is to cooperate with the stamping machine, the feeder and the smoke guide car to load the coal cake into the carbonization chamber of the coke oven. At present, the original design of the coal loading car is that the coal cake is sent into the carbonization chamber by the coal supporting bottom plate and the rear baffle during the coal loading process. A 60x60mm slot hole is opened in the movable wall of the coal box device close to the front baffle, and the hook head of the locking hook is extended from the slot hole to lock the rear baffle. The locking device locks the rear baffle of the coal loading car during the retraction process of the coal supporting bottom plate, and keeps the coal cake in the carbonization chamber. This design solves the problem that the rear baffle equipment locking can send the coal cake into the carbonization chamber. However, in the actual operation process of the equipment, there is a large amount of coal leakage or slot hole blockage in the locking hook slot hole. The coal powder falls from the slot hole to the coke oven platform and the machine side rail foundation, and a large amount of coal powder accumulates on the equipment frame. When the wind blows, the pulverized coal scatters everywhere, causing serious dust emission on the side of the coke oven machine, corroding the equipment frame, polluting the equipment such as the speed reducer, and causing a lot of work and environmental pollution to the post personnel.

[0032] In order to solve the above problems, the present application provides a coke oven coal loading car locking device. The embodiments of the present application will be further described below with reference to the accompanying drawings.

[0034] It should be noted that the front baffle, the rear baffle 113, the first movable wall plate 114, the second movable wall plate 115 and the coal supporting bottom plate 116 form the coal box, wherein the coal supporting bottom plate 116 is arranged on the bottom plate of the coal box, the first movable wall plate 114 and the second movable wall plate 115 are arranged on the two sides of the coal box, and the front baffle and the rear baffle 113 are arranged on the front side and the rear side of the coal box respectively.

[0035] It should be noted that, in the production process of the stamp-charged coke oven, a coal supporting plate is needed to send the stamp-charged coal cake into the carbonization chamber from the coke charging car, the coal supporting bottom plate 116 is driven by the chain wheel transmission mechanism, and the coal supporting bottom plate 116 and the coal cake thereon and part of the rear baffle 113 are sent into the coke oven when the coal is sent; when the chain wheel transmission mechanism pulls the coal supporting plate backward, the rear baffle 113 is temporarily fixed in front of the oven by the cooperation of the locking hook rack and the two first locking hooks 120, and the coal cake is blocked in the oven.
