Abstract
The invention relates to a high-tightness continuous and uniform feeding device comprising a delivery cavity, one end of the delivery cavity is provided with a motor driving device, a feeding port is arranged on the side wall, close to the motor, of one end of the delivery cavity, the other end of the delivery cavity is provided with a discharge port, a rotary shaft is arranged on a central shaft wire in the delivery cavity and is connected with the motor driving device, and a helical blade is arranged on the rotary shaft. By adopting the scheme, the invention has the advantages that the feeding device has simple structure so as to be especially suitable for workshops require compactness; since the tightness is formed by the self extrusion of materials, the feeding device has good tightness and ensures that air pressure in a mill is not affected by outside; since the helical blade is cast by high-chromium iron, the feeding device has strong wear-resisting capacity and simple and convenient replacement; and the feeding device ensures continuous, uniformly and direct blanking to a milling machine through spiral delivery and blanking, and has small influence on the vibration of the mill and more stable operation.
Description
One, technical field
The invention belongs to field of mechanical technique, particularly the even continuous flow rate device of a kind of high leakproofness in iron and steel, the cement plant vertical mill system.
Two, background technology
At present, iron and steel, cement plant vertical mill system particularly slag mill generally are all worked under condition of negative pressure, and integrated work such as powder are milled, dry, selected in realization, and wherein the variation of air-flow is the most key for this, directly influences the fineness and the output of end product.Therefore how keeping the stable of grinding machine air pressure inside is an important subject.Grinding machine just is feed inlet and outlet with extraneous passage of getting in touch, and is in air pressure inside under the situation of negative pressure, and charging aperture is the most possible position that leakage occurs.And will address this problem, this charging aperture to grinding machine has proposed higher seal request.Because slag mill body is bigger, and is bad if vibration is handled, and will influence the operate as normal of grinding machine greatly, must be to enter grinding machine continuously uniformly so require material.
Three, summary of the invention
Goal of the invention: in order to address the above problem, the invention provides a kind of high-tightness continuous and uniform feeding device, i.e. the unequal distant screw drawing-in device.This device can reach isolated grinding machine inner air and outer air at operation process voluntarily by material, realizes the requirement of high sealing, and can reduce the impact shock to grinding machine greatly by directly continuous convey materials uniformly to grinding machine, guarantees the operate as normal of grinding machine.
Technical scheme: a kind of high-tightness continuous and uniform feeding device, comprise the conveying cavity, carry an end of cavity to be provided with transmission gear for electric motor, carry cavity to be provided with spout near the sidewall of motor one end, carry the other end of cavity to be provided with discharging opening, carry the interior axis of cavity to be provided with rotating shaft, described rotating shaft is connected with transmission gear for electric motor, and rotating shaft is provided with helical blade.
Described helical blade is the unequal distant screw blade, and the number of blade is 3～5.
On the described helical blade with discharging opening near the helical angle of a blade less than 35 °.
Described helical blade is cast by rich chromium cast iron.
Described conveyor chamber body sidewall is provided with the grinding machine adpting flange.
Beneficial effect:
1. the not design of equidistant pitch.Guarantee in cavity, to form seal section in the process of helical feed of material, rationally arrange interlobate pitch.At the slag material, compressibility does not almost have, and the selection of pitch can be faded to last 100-200mm and can be reached sealing effectiveness by the 300mm of beginning.
2. the design of helical blade helical angle.Reach sealing effectiveness, need to guarantee that material rests on the blade and blanking voluntarily not when shutting down.At the slag material, angle of repose is 35 °, and the helical angle of therefore last a slice helical blade needs less than 35 °.
3. the helical blade material selects for use.At the slag feeding, hardness ratio is bigger, and the wearing and tearing ability is strong, recommends to select for use rich chromium cast iron to cast helical blade, strengthens its service life.
Adopt such scheme, following advantage arranged:
1, simple in structure, require the especially suitable of compactness for factory building;
2, formed airtightly by self extrusion of materials, good seal performance guarantees that the grinding machine air pressure inside is not subjected to ectocine;
3, rich chromium cast iron casting helical blade, antiwear property is strong, changes simple and convenient;
4, by the helical feed blanking, guarantee that evenly directly blanking is to grinding machine continuously, little to grinding machine vibration effect, it is more stable to turn round.
