Abstract
A feeding box of a jet floatation machine is a rectangular box formed through welding of metal plates, one side of the box is communicated with a feeding pipe, the other end of the box is fixedly connected with a first tank end plate of the floatation machine, a longitudinal baffle arranged vertically is fixedly connected inside the feeding box, and the upper portion of the feeding box is provided with a minor-caliber discharging pipe communicated with the atmosphere. Compared with the prior art, the discharging pipe and the longitudinal baffle are arranged inside the feeding box, because the discharging pipe is communicated with the atmosphere, the siphon action is destroyed, so that coal slurry in the tank which is lower than horizontal plane of the upper end face of the longitudinal baffle is prevented from flowing back into a feeding pool; and simultaneously, fed materials with pressure are stopped by the longitudinal baffle and the longitudinal baffle is climbed over when the pressure is eliminated, the coal slurry is forced to enter the floatation machine tank through a channel along the horizontal direction uniformly, and the separation effect of the floatation machine is guaranteed.
Description
Technical field
The utility model relates to and a kind ofly is applied to wet coal preparation factory granularity＜0.50mm slime separation, utilizes ejector principle and microvesicle to separate out the feed box that mechanism realizes the air jet flotation machine of coal slurry inflation, bubble mineralization.
Background technology
According to incompletely statistics; China has 500 air jet flotation machines of surpassing to work in wet coal preparation factory approximately at present; Every air jet flotation machine all is provided with feed box at feeding end, and purpose is that the floatation feed that transports with pipeline pressure is fed the first tank of flotation device more uniformly.But, practice finds in using; There are two problems: the one, when flotation device temporarily shuts down; Because the tens of cubic meters in the siphonage tank will flow backward to the pan feeding pond from the pan feeding pipeline to over one hundred cubic metre coal slurry, when flotation device recovers running, at first coal slurry will be full of tank again; The 2nd, because of pan feeding is to have to press to feed, so the pressure coal slurry in the feed box is with the feeding pipe center quick uneven entering flotation tank of serving as theme, thereby influences the separating effect of flotation device.
The utility model content
The utility model purpose is the deficiency that exists to prior art, and a kind of air jet flotation machine feed box simple in structure is provided.
Realize that above-mentioned purpose adopts following technical scheme: a kind of air jet flotation machine feed box; This feed box is the rectangle chest that sheet metal is welded; Casing one side is communicated with feeding pipe; The first tank end plate of opposite side and flotation device is affixed, the affixed one vertical midfeather that is provided with in the said feed box casing; Said feed box casing top is provided with an open to atmosphere small-bore gas outlet.
Midfeather places feed box middle part, and the both sides of midfeather and feed box biside plate are affixed, the bottom surface of midfeather and feed box base plate are affixed; The upper surface of said midfeather is apart from feed box top board 200-500mm.
Gas outlet is positioned at the top with the affixed tank end plate of feed box, and the installation site of this gas outlet is higher than the midfeather upper surface, and the outlet of this gas outlet vertically downward.
Compared with prior art, be provided with gas outlet and midfeather in this feed box disclosed in the utility model,, make the interior coal slurry of the tank that is lower than midfeather upper surface horizontal plane do not flowed backward to the pan feeding pond because the logical atmosphere of gas outlet has destroyed siphonage; Expect to receive keeping out of midfeather owing to having to be pressed into simultaneously, cross midfeather behind the elimination pressure, force the coal slurry along continuous straight runs to get into the flotation device tank via passage uniformly, thereby guaranteed the separating effect of flotation device.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: feeding pipe 1, midfeather 2, feed box 3, gas outlet 4, tank end plate 5, passage 6.
The specific embodiment
Referring to accompanying drawing 1; The rectangle chest that the disclosed this air jet flotation machine feed box 3 of the utility model is welded for sheet metal; Casing one side is communicated with feeding pipe 1, and the first tank end plate of opposite side and flotation device 5 is affixed, affixed one midfeather that vertically is provided with in feed box 3 casings; Said feed box 3 casing tops are provided with an open to atmosphere small-bore gas outlet 4.
Midfeather 2 places feed box 3 middle parts, the bottom surface of the both sides of midfeather 2 and the welding of feed box 3 biside plates, midfeather 2 and the welding of feed box 3 base plates.The upper surface of midfeather 2 is apart from feed box 3 top board 200-500mm.
Gas outlet 4 is positioned at the top with the affixed tank end plate 5 of feed box 3, and the installation site of this gas outlet 4 is higher than midfeather 2 upper surfaces, and the outlet of this gas outlet 4 vertically downward.Gas outlet 4 L-shaped shapes, its entrance is vertical with the tank end plate, promptly is horizontally disposed with, and its outlet section is vertically downward.
Setting up when making flotation device suspend running of midfeather and gas outlet, the interior coal slurry of tank that is lower than midfeather upper surface horizontal plane is not flowed backward to the pan feeding pond; Be pressed into simultaneously and expect that receiving midfeather keeps out, cross midfeather behind the elimination pressure, force the coal slurry along continuous straight runs to get into the flotation device tank uniformly.
The course of work of the utility model is: coal slurry has pressure to feed flotation device feeding pipe 1 and flotation device feed box 3 through pump, and gets into the flotation device tanks through passage 6.When flotation device temporarily shuts down,, make the interior coal slurry of the tank that is lower than midfeather 2 upper surface horizontal planes do not flowed backward to the pan feeding pond because gas outlet 4 logical atmosphere have destroyed siphonage; Expect to receive keeping out of midfeather 2 owing to having to be pressed into simultaneously, cross midfeather 2 behind the elimination pressure, force the coal slurry along continuous straight runs to get into the flotation device tanks via passage 6 uniformly.
