Description

Technical Field

[0001] The utility model belongs to the technical field of ore dressing inspection, and in particular relates to a slurry feeding device suitable for a mining sample reduction bucket. Background Art

[0002] The liquid reduction barrel for mineral processing is a device that automatically reduces the pulp samples taken to detect the concentration, fineness and grade during the mineral processing process during the process control of the mineral processing plant. It is widely used in the sampling of process samples in the mineral processing plant. During the sampling process, it was found that due to the small feed port of the umbrella plate of the reduction barrel, the slurry is prone to overflow from the center of the umbrella plate due to the large sample volume during sampling, or the slurry enters the reduction barrel and the umbrella plate. The slurry is umbrella-shaped and the sample cannot enter the center of the umbrella plate, which affects the representativeness of the sampling. On the other hand, the umbrella plate of the existing reduction barrel is fixed and cannot be adjusted. When sampling in different height environments, it will cause inconvenience in sampling. Especially when sampling at a high position, it is necessary to install a guide pipe to prevent scattering and loss, while low-position sampling will cause overflow due to fast feeding. Therefore, it is necessary to develop a method to improve the umbrella plate of the existing reduction barrel to solve the overflow problem. Utility Model Content

[0010] In order to enable those skilled in the art to better understand the technical solution of the utility model, its specific implementation method is described in detail below with reference to the accompanying drawings.

[0011] like Figures 1 to 3 The slurry feeding device suitable for the mining sample reduction bucket shown in the figure comprises a column 1 and an equalizing umbrella plate 6 arranged on the column 1, wherein at least three columns 1 are arranged around the outer periphery of the equalizing umbrella plate 6, and the lower part of the column 1 is installed on the reduction machine through bolts or connecting sleeves, and a limiting slide rail 2 is arranged on the inner side of the lower part of each column 1, and a boss 3 is arranged on the column 1 at the lower end of the limiting slide rail 2, and the equalizing umbrella plate 6 is arranged on the boss 3 and connected to the limiting slide rail 2 through a slider, and a buffer 5 is arranged between the equalizing umbrella plate 6 and the boss 3, and the equalizing umbrella plate A vibrator 8 is arranged on the outer bottom or outer wall of the plate 6. When the vibrator 8 is running, the limit slide rail 2 limits the evenly-dividing umbrella plate 6 through the slider, so that it can move to a certain position without being offset, and solves the problems of poor vibration effect caused by rigid connection and deformation and fracture of the connection part. A buffer storage bin 9 is arranged above the evenly-dividing umbrella plate 6, and the buffer storage bin 9 is connected to the column 1 through an adjusting rod 10. A U-shaped or V-shaped structure is arranged at the bottom of the buffer storage bin 9, and a material guide pipe pointing to the center of the evenly-dividing umbrella plate 6 is provided.

[0012] The evenly-dividing umbrella plate 6 is arranged in a W-shaped structure, and at least three distribution pipes 7 are arranged on the circumference of the inner recessed part of the evenly-dividing umbrella plate 6. Each distribution pipe 7 is provided with a regulating valve. The arrangement of multiple distribution pipes 7 and regulating valves can effectively control the discharging speed and amount of the evenly-dividing umbrella plate 6, and the distribution pipes 7 are connected to the reduction barrel.

[0013] The dividing umbrella tray 6 is detachably provided with a partition plate 12 that matches its internal shape. The number of the partition plates 12 is consistent with the number of the distribution tubes 7. The partition plates 12 are connected as a whole by a circular ring 13 to prevent the partition plates 12 from being offset due to pressure, and the circular ring 13 is arranged at the top and / or bottom of each partition plate 12 to divide the material entering the dividing umbrella tray 6 into equal portions consistent with the number of the distribution tubes 7, so that each distribution tube 7 can receive and evenly discharge the material.

[0014] The adjusting rod 10 is a metal rod, one end of which is fixedly connected to the buffer storage bin 9 , and the other end of which is provided with a clamp 11 , which is connected to the column 1 .

[0015] The limiting flanges 4 are equidistantly provided from the middle to the top of the column 1, the spacing between adjacent limiting flanges 4 is not less than the height of the hoop body of the clamp 11, and the protruding distance of the limiting flanges 4 is not less than the thickness of the hoop body of the clamp 11. The limiting flanges 4 are utilized to support and limit the position of the clamp 11 to prevent the clamp 11 from sliding down along the column 1 due to excessive weight of the material in the buffer storage bin 9.

[0019] The working mode of the utility model is as follows: the material first enters the buffer storage bin 9, and then is discharged from the buffer storage bin 9 to the evenly distributing umbrella plate 6, and then is distributed to the shrinking bucket by the evenly distributing umbrella plate 6. In order to solve the problem of material clogging in the evenly distributing umbrella plate 6, during use, the vibrator 8 is started to vibrate the evenly distributing umbrella plate 6, and the material is shaken off from the evenly distributing umbrella plate 6 and the inner wall of the distribution pipe 7; in order to adapt to the height of different feeding mechanisms, during use, the position height of each clamp 11 on the column 1 is adjusted so that the buffer storage bin 9 can receive the material, avoiding leakage, scattered material, or the situation that a conduit needs to be installed when no material is received; on the other hand, in order to ensure that the material in the buffer storage bin 9 can fall into the evenly distributing umbrella plate 6 at any height, a telescopic pipe section 15 and a discharge pipe section 16 are provided, the telescopic pipe section 15 is used to guide the material, and the discharge pipe section 16 ensures that the discharge is not disturbed and prevents blockage.
