Embodiment

[0040] For the cemented filling slurry with a mass concentration of 70%, the slurry is made by mixing tailings, cement and water, and the concentration of its different layers changes with time. Take 800mL of slurry and place it in the discharge cylinder 4 with a diameter of 50mm. After standing still for one hour, move the electric telescopic rod 8 to correspond to the guide hole 12 and fix it, so that the electric telescopic rod 8 moves up and pushes the piston 5 to move. Thereby, the slurry in the discharge cylinder 4 is pushed into the transfer platform 1 through the round hole, and the push plate 2 on the transfer platform 1 is used to push the slurry through the square hole into the square container 3, and then the sample with the slurry is taken out. Square container 3, install a new square container 3 again, the remaining slurry is divided repeatedly according to above-mentioned steps successively, wait to take out all slurry, measure the concentration of slurry in diff...

Abstract

The invention discloses a sampling device for obtaining cemented filling slurry on different layers and a working method thereof. The sampling device comprises a transfer device, a charging device anda base. The transfer device comprises a transfer platform, a push plate and a square container. The push plate is arranged between baffles on both sides of the transfer platform, and the square container is located at the bottom of the transfer platform. The charging device is composed of a discharge cylinder, a piston, a sealing ring and a fixing ring. The piston is arranged inside the dischargecylinder, the sealing ring is arranged outside the piston, and the discharge cylinder is mounted on the base by the fixing ring. The base is composed of a support frame, an electric telescopic rod and a sliding rod. The sliding rod is located on the lower portion of the support frame, and the electric telescopic rod is mounted on the sliding rod to be arbitrarily moved or fixed. The transfer device is installed at the upper end of the discharge cylinder to transfer the slurry, and the electric telescopic rod pushes the piston inside the discharge cylinder to sample the slurry on the differentlayers. The device is simple in operation and high in practicability, and achieves the effect of obtaining slurry samples on the different layers under the premise that the internal structure of thecemented filling slurry is not disturbed.

Description

technical field [0001] The invention relates to a sampling device and a working method for obtaining cemented filling slurry in different layers, and belongs to the technical field of mine filling and material sampling. Background technique [0002] In recent years, the construction of green mines and the development of green mining industry have become the behavior program, development goals and urgent needs of the Chinese mining industry. As a green mining technology, filling mining is one of the important technical means of scientific mining. [0003] Cemented filling is an important branch of mine filling mining technology. In this technology, solid waste such as tailings, gangue, and fly ash is mixed with an appropriate amount of cementitious material, mixed with water to make a cemented filling slurry, and then pumped or The filling slurry is transported along the pipeline to the goaf for filling operation in the way of self-flow, and then the slurry is solidified in ...
