Description

Electronic powder material feeding device

Technical field

This utility model belongs to electronic kiln technical field of auxiliary facilities, is specifically related to a kind of electronic powder material feeding device.

Background technology

Aforesaid electronic powder material such as color phosphor, lamp powder, Barium metatitanate., strontium titanates, yttrium oxide, zirconium oxide, aluminium oxide, bismuth oxide, lead zirconate titanate, LiFePO4 and ferromagnetic oxide powder, etc..

Such as industry institute, aforesaid electronic kiln is to burn till the special equipment of the aforementioned electronic powder body material for making electronic devices and components and generally occur with the form being matched in production line.nullSo-called production line refers to be equipped with one for the saggar automatic delivering mechanism of automatic transport saggar around electronic kiln，This saggar automatic delivering mechanism is arranged between electronic kiln burner hearth entrance and electronic kiln furnace outlet，And this saggar automatic delivering mechanism requires to include electronic powder material automatically solve crushing device according to technological requirement or station、Saggar mechanical feed (feed) device、Saggar automatic material pouring device、Saggar automatic cleaning apparatus、Crack inspection device for sagger and material containing saggar introducing device etc.，This be may refer to invention patent mandate notification number CN103521314B(electronic powder material machine for decomposing and smashing)、The saggar automatic material pouring device of CN103512368B(electronic powder manufacture of materials streamline)、The saggar automatic cleaning device of CN103528389B(electronic kiln automatic production line)、CN103529044B(crack inspection device for sagger)、The saggar automatic Weighing feeding device of CN103528381B(electronic kiln production line)、CN103528380B(saggar even distributor)、The flaw saggar automatic rejection more changing device of CN103512367B(electronic kiln automatic production line) and the saggar Automatic continuous feeding device of CN104165524B(electronic kiln)，Etc..

Read by the description of aforementioned CN103528381B and CN104165524B: electronic powder material feeding device uses screw-rod structure, screw-rod structure has the strong point that volume is little, but there is following shortcoming: one, electronic powder material is existed fastidious property, because the change along with the electronic powder material with different qualities or the different physical property of title, spiral way on screw rod is difficult to general, such as after electronic powder production firm changes electronic powder material, the so hand of spiral or even pitch of screw rod needs respective change, current way is to change corresponding screw rod, but change screw rod to bother the most again, and need to be taken on by professional；They are two years old, in order to ensure the intensity of screw rod, metal screw need to be used, and the screw rod of metal material easily causes the pollution that cleannes require harsh electronic powder material, current solution is in screw surface coated non-metallic coating, but nonmetallic coating easily comes off from screw rod in use for some time and enters (being mixed into) electronic powder material, affects the quality of electronic powder material；They are three years old, it is difficult to meet the measuring requirement accurately or even accurately to the electronic powder material fed.

Substitute screw rod with vane pump and substantially can solve the problem that aforementioned technical problem, and can be seen in disclosed Chinese patent literature, typically recommend there be " high-pressure rotating material feeder " such as document A. Authorization Notice No. CN2815979Y；Document B.CN103662682B is provided with " a kind of rotary vane wheel adjustable vane feeder "；Document C.CN104085690A introduces " rotary feeder of a kind of low speed continuous uniform feed ".Document A has achievement (specifically can be found in Instructions Page 2 final stage) for housing with the radial seal of impeller and the axial seal for impeller Yu end cap；Document B regulates for the compensation after blade wear reference (specifically can be found in description the 0015th section), but blade and vane frame need to be designed to split-type structural, is inserted in the groove being embedded in vane frame by blade during assembling；The opening shape of discharging opening has been made to improve (specifically can be found in description the 0025th to 0026 section) by document C.

Above-mentioned document A, the something in common of B and C is all directly to be taken on the two ends accent to pump housing chamber by end cap (a pair) to close, and reached, by the sealing ring being arranged on end cap, the purpose that the fluted disc axle to fluted disc is implemented to seal, then logical fraud below existing: one, owing to the side in opposite directions of a pair end cap is directly facing fluted disc chamber and owing to the supporting pair of bearings of fluted disc axle and the side in opposite directions for a pair sealing ring to end cap seal that is arranged on end cap are also directly facing fluted disc chamber, thus there is the anxiety to material pollution, such as when being applied to feed at regular time and quantity the aforesaid electronic powder material that Control of Impurities is required the most harsh top grade, then cannot meet the purity requirements exempting to pollute；They are two years old, during a pair end cap of removal, protect because the two ends of fluted disc lose covering of end cap and be in the naked state of dew when bearing and sealing ring being changed, thus subject to the trifle in the world invasion and attack in environment, when being again introduced into duty after service is complete, aforesaid trifle in the world is brought in material；They are three years old, due to cannot in time and whether the aforesaid sealing ring that correctly judges is in intact and can continue to play desired sealing effectiveness, thus can only periodically or non-periodically inspection, and when inspection again entirely with the subjective judgment of inspection personnel, thus there is certain blindness.Although after sealing ring lost efficacy, material can go out from bearing portion disperse, and following this shows to change with the least delay possible sealing ring, but bearing has created impact due to material, thus simultaneously to bearing cleaning or even replacing bearing, thus the increase of the wasting of resources and maintenance cost must be caused；They are four years old, the fluted disc axle drive mechanism (document A and C is not disclosed for ordering about the power drive mechanism that fluted disc axle moves) be given due to document B uses what Chain conveyer mode was connected with fluted disc through-drive, thus on the one hand cause power transmission loss big because transmission link, it is unfavorable for energy-conservation, is on the other hand difficult to meet the requirement correctly or even accurately feeding doses.

For above-mentioned prior art, it is necessary rational modification in addition, made design repeatedly for this applicant, finally define technical scheme described below and under taking secrecy provision development centre test chamber the applicant be simulated test, result proves practicable.
