The invention discloses a ZWY mine crawler excavation loader multifunctional conveying device, which includes a loader body, the loader body includes a base, a driving crawler is installed on the lower end of the base, and a driver's cab is fixed on the upper end of the base. An excavation mechanism is installed on the front side of the base, and a rolling feeding mechanism and a transmission mechanism are respectively installed on both sides of the rear end of the base. The two sides of the rectangular dish are connected through. A rolling block is fixed on the inner bottom of the rectangular dish close to the side of the excavation mechanism. The upper end of the rolling block is provided with a rolling roller 1 and a rolling roller 2, and the rolling roller One and rolling roller two are all rotatably installed on the front and rear end inner walls of the rectangular dish. The invention has compact structure and stable operation, and can adjust the position and height of the ore discharge point, so as to meet the requirements of ore loading under different working conditions and ensure the safety of mining.

The invention relates to a coal tar whole-fraction fluidized bed hydrogenation method which comprises the following steps: (1) heating coal tar whole fraction and mixing with circulation oil of a fluidized bed reactor; (2) mixing the mixture in the step (1) and hydrogen, dissolving the hydrogen, and enabling the mixture to enter a gas-liquid separator; (3) enabling a gaseous phase on the top of the gas-liquid separator in the step (2) to enter a fixed bed hydrogenation reactor from the top of the reactor, and enabling a liquid phase to enter the fluidized bed reactor from the bottom of the reactor so as to carry out a hydrogenation reaction; and (4) arranging a three-phase separator on the upper part inside the fluidized bed reactor in the step (3), discharging the gaseous phase separated from the three-phase separator from the top of the fluidized bed reactor to the fixed bed hydrogenation reactor in the step (3), and taking at least one part of the liquid phase through a circulatory system as the circulation oil in the step (1). Compared with the prior art, the method disclosed by the invention has the advantages that the steady operation problem existing in coal tar whole-fraction fluidized bed hydrogenation can be effectively solved, and the coal tar whole-fraction fluidized bed hydrogenation reaction effect is improved.

The invention discloses a shaft displacement prevention device for a mechanical transmission type grate cooler. The device comprises a base, mounting mechanisms are arranged at the two ends of the base, a rotating shaft and an auxiliary shaft are movably arranged between the two mounting mechanisms through bearings correspondingly, fixing discs are fixedly arranged on the outer sides of the two ends of the middle of the auxiliary shaft, a baffle is fixedly arranged on the outer side of the middle of the rotating shaft, the baffle is arranged between the two fixing discs, and fixing mechanismsare arranged at the two ends of the rotating shaft and the auxiliary shaft. According to the device, the auxiliary shaft is driven to rotate through a gear while the rotating shaft rotates, meanwhile,a ball is driven to rotate while rotating, then lubricating oil on the inner side of an oil box is brought to the bearing where the rotating shaft is located and the bearing where the auxiliary shaftis located through the ball for lubricating and cooling, so that the situation that the bearings are damaged and broken due to the facts that rotating is performed for a long time and the lubricatingoil is not provided for lubricating and cooling and other problems occur, so that the production efficiency is reduced is avoided.
