Abstract
The utility model discloses a novel feeding device of a flotation column, which comprises a square coal bin body, wherein a feeding hole is arranged at the top end of the coal bin body, a discharging hole is arranged at the bottom end of the coal bin body, a plurality of elastic vibration devices are symmetrically arranged on the inner walls at two sides of the coal bin body, and each elastic vibration device comprises a fixed seat, a compression spring and a vibration plate; the utility model has the advantages that: the utility model has simple structure, and the elastic vibration device and the air cannon are designed in the coal bunker, so that the elastic vibration device can reduce the abrasion of raw coal ores on the inner wall of the coal bunker, thereby prolonging the service life of the coal bunker; the ventilation filter plate device is designed below the elastic vibration device, so that the ventilation filter plate can be effectively prevented from being blocked by coal mine stones, the ventilation effect is good, and the blocking of coal mine stones due to caking is prevented; once the coal bunker is blocked, the air cannon can be started, and the impact airflow of the air cannon can enable the elastic vibration device to vibrate to assist in dredging the coal bunker.
Description
The technical field is as follows:
the utility model relates to a coal washing equipment technical field especially relates to a novel pan feeding device of flotation column.
Background art:
in the prior art, coal dressing pulp and a medicament are fully mixed and proportioned in a preprocessor, then the mixed pulp is sent into a flotation column for flotation through a pipeline, and during flotation, ore particles can be selectively attached to bubbles and finally rise to a liquid level to achieve the purpose of flotation; in the process, the kinetic energy is overlarge when the ore pulp enters the flotation column from the pre-processor, and the ore pulp in the flotation column is disturbed, so that part of bubbles are broken, and the flotation efficiency is reduced.
The utility model has the following contents:
an object of the utility model is to provide a novel pan feeding device of flotation column.
The content of the utility model is as follows: a novel feeding device of a flotation column comprises a preprocessor 1, a flotation column 2 and a feeding ring pipe 3, wherein the feeding ring pipe 3 is sleeved at the bottom of the flotation column 2, the feeding ring pipe 3 is outwards communicated with a feeding main pipe 4, the other end of the feeding ring pipe 3 is communicated with the preprocessor 1, the feeding main pipe 4 is inwards provided with a plurality of tangential material distributing pipes 5, the other ends of the tangential material distributing pipes 5 are communicated with an inner cavity of the flotation column 2, the tangential material distributing pipes 5 are uniformly distributed and arranged along the circumferential direction of the feeding ring pipe 3, the axis of the tangential material distributing pipes 5 is not intersected with the axis of the feeding ring pipe 3, a flow stabilizing ring 6 is concentrically and horizontally arranged in the flotation column 2, the installation height of the flow stabilizing ring 6 is the same as that of the tangential material distributing pipes 5, and the top end of the flow stabilizing ring 6 is fixedly connected with the bottom end of a steel wire rope 7, the top end of the steel wire rope 7 is fixedly connected with a fixing frame 8, and the fixing frame 8 is fixedly installed at the top end of the flotation column 2.
Further, the outer circumferential surface of the flow stabilizing ring 6 is conical.
The utility model has the advantages that: the utility model discloses simple structure divides the material pipe to carry out pan feeding pipe and steady flow ring through design pan feeding ring canal, tangential, avoids the direct center of rushing into the flotation column of material, reduces the disturbance to the interior thick liquid of flotation column, improves flotation efficiency.
Description of the drawings:
fig. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a top view of the flotation column, feeding ring pipe, tangential material distributing pipe and flow stabilizing ring;
FIG. 3 is a schematic view of the mounting structure of the stabilizer ring;
in the figure, a preprocessor 1, a flotation column 2, a feeding ring pipe 3, a feeding main pipe 4, a tangential material distributing pipe 5, a steady flow ring 6, a steel wire rope 7 and a fixing frame 8.
The specific implementation mode is as follows:
as shown in fig. 1, a novel feeding device for a flotation column comprises a preprocessor 1, a flotation column 2, a feeding ring pipe 3, a feeding main pipe 4, a plurality of tangential material distributing pipes 5, a plurality of flow stabilizing rings 6, a feeding main pipe 3, a plurality of tangential material distributing pipes 5, a plurality of flow stabilizing rings 6 and a plurality of tangential material distributing pipes 5, wherein the feeding ring pipe 3 is sleeved at the bottom of the flotation column 2, the feeding ring pipe 3 is outwardly communicated with the feeding main pipe 4, the other end of the feeding ring pipe 3 is communicated with the preprocessor 1, the feeding main pipe 4 is inwardly provided with the tangential material distributing pipes 5, the other end of the tangential material distributing pipes 5 is communicated with an inner cavity of the flotation column 2, the tangential material distributing pipes 5 are uniformly distributed and arranged along the circumferential direction of the feeding ring pipe 3, the top end of the current stabilizing ring 6 is fixedly connected with the bottom end of the steel wire rope 7, the top end of the steel wire rope 7 is fixedly connected with the fixing frame 8, and the fixing frame 8 is fixedly installed at the top end of the flotation column 2.
The working principle is as follows: when the device is used, coal slurry enters the flotation column 2 through the feeding main pipe 4, the feeding ring pipe 3 and the tangential material separating pipe 5, so that the coal slurry enters the flotation column 2 from the tangential direction, and the coal slurry with a certain speed firstly encounters the flow stabilizing ring 6 to further reduce the speed, so that the interference of the feeding on the coal slurry of the flotation column is reduced, and the flotation efficiency is improved.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
