Abstract
The present invention has designed a kind of two porose (or breach) end cap and has been rotated synchronously by the continuous cropping of axle phase, and the multi-compartment tube in the middle of making in turn constitutes feeding warehouse successively and goes out feed bin, thereby reaches the metering feed valve of lock feeding purpose.
Description
The invention belongs to bulk solid mechanical equipment field, specifically a kind of metering feed valve.
At present has bulk solid feeding equipment than atm difference for inlet point and discharging opening, usually all adopt the impeller feeding machine to make lock feeding, the impeller feeding machine is by the impeller of rotation material to be scraped to discharging opening from inlet point, reaches the purpose of lock wind with the compartmentation of impeller vane.Material will be made half circular motion along turned cavities in the impeller feeding machine, thus the half cycle cavity serious wear that contacts with material and in addition the half cycle cavity wear and tear less, so it is an irregular wear, this wearing and tearing trimming difficulty.And power consumption is big, lock wind poor performance, and service life is low.
The present invention seeks to problem at above-mentioned existence, having designed a kind of two porose (or breach) end cap is rotated synchronously by the continuous cropping of axle phase, multi-compartment tube in the middle of making in turn constitutes feeding warehouse successively and goes out feed bin, thereby reaches lock feeding purpose metering feed valve.
The technology of the present invention solution:
Metering feed valve is characterized in that it is on the center shaft that multi-compartment tube is positioned at the main shaft, and the upper and lower side cover plate respectively has several holes (or breach), and staggers successively in each hole (or breach) in the upper and lower side cover plate.
Advantage of the present invention: because material is only done free fall, do not make compulsory circular movement, therefore it is little to consume energy, it is little and even to wear and tear, the a small amount of wearing and tearing of bulkhead can not influence lock wind performance, wearing and tearing between multi-compartment tube end face and the end cap are easy to trimming (as long as regular grinding multi-compartment tube end face and end cap, and the adjustment jam nut gets final product), therefore it to have cost low, lock wind performance is good, energy consumption is low, advantages such as long service life, owing to add a baffle plate on the inlet point next door, therefore each little storehouse all can be filled when charging, thereby can be used as the metering outfit of positive displacement continous way, this metering method is especially suitable for the prose style free from parallelism of good flowing properties.Because of rotating its inlet point position, in big storehouse wholecircle week evenly charging improved the factor of utilization of big storehouse capacity, if discharging opening is the high pressure gas transmission pumps, take turns even discharging its this wholecircle week to also help the fluidization of bulk solid.

Fig. 4 is a bottom end cover C-C section-drawing of the present invention.
1 is the storing warehouse among Fig. 1, the 2nd, and the dustproof awl of wheel word (buncher and reductor), the 3rd, wheel word, the 4th, last fixed beam, the 5th, coupler, the 6th, head bearing sealed chamber, the 7th, head bearing, the 8th, main shaft, the 9th, upper end cover jam nut, the 10th, plate washer, the 11st, upper end cover, the 12nd, multi-compartment tube, the 13rd, bottom end cover, the 14th, bottom end cover jam nut, the 15th, following fixed beam, the 16th, lower bearing, the 17th, discharging opening flange.
Below in conjunction with accompanying drawing the present invention is further described:
When main shaft 8 drives upper end cover 11 and bottom end cover 13 rotations, 2 in the multi-compartment tube 12
#Little storehouse is a feeding warehouse, 4
#Little storehouse is for going out feed bin, 1
#Little storehouse is a storage bin, 3
#Little storehouse is a hole capital after selling all securities, because 2
#Little storehouse and 4
#Little storehouse is spaced, and therefore, in input and output material, can not run wind because of feeding produces though exist bigger draught head between the feed inlet and outlet, has reached good lock wind purpose.Behind main shaft 8 half-twists, 3
#Little storehouse has become feeding warehouse, and 2
#Little storehouse is a storage bin, 4
#Little storehouse is a hole capital after selling all securities, 1
#Little storehouse is feed bin, and along with the not stall of main shaft 8 is moving, the turnover feed bin carries out successively by turns, thereby has reached the purpose of continuous feeding and discharging.
