The magnetic seal unloading valve adopts the magnetic sealing device as a main seal and a sealing strip sealing device of the impeller bin as an auxiliary seal to achieve a sealing effect on a bonding part of the magnetic sealing device and the impeller bin, is high in sealing air tightness, small in air leakage and simple in structure, can adjust according to the system working pressure, and is few in external condition limits, strong in practicability and wide in application range.
Description
technical field
What the present invention relates to is a kind of discharge gate, specifically a kind of magnetic seal discharge gate.
Background technology
At present, discharge gate is applicable to the handling of dry powdery and granule materials, is the device for discharging being applied to the equipment such as grinding machine, dryer, drying tower, feed bin, grain depot; Material due to conveying needs airtight and have in the system of pressure, negative pressure and transmit, more and more higher to the requirement of the sealing air-tightness of discharge gate, air leakage and delivery pressure; Current discharge gate mainly adopts the sealing of flexible sealing and positiver sealing two kinds of forms, and it seals poor air-tightness, air leakage is large, friction force is large, can not do the high airtight sealing charging of vacuum drying apparatus and use.
Summary of the invention
The problem to be solved in the present invention overcomes the deficiency that existing discharge gate exists, provide a kind of structure simple, sealing air-tightness be strong, running time air leakage few magnetic seal discharge gate.
In order to achieve the above object, the present invention is achieved through the following technical solutions: this magnetic seal discharge gate is made up of valve, change speed gear box and motor; Valve, change speed gear box and motor are connected to one by screw.
Described valve is made up of valve body, impeller feed bin, side cover, bearing, screw, magnetic sealing device;
Described magnetic sealing device is in the inside of valve body, and magnetic sealing device and valve body are connected to one; Magnetic sealing device is the magnetic fields utilizing magnetic material, and compensated ring component and uncompensated ring assembly are attracted each other, and realizes compensated ring and uncompensated ring friction face and fits and play sealing function;
Magnetic sealing device is device for sealing magnetic fluid or device for magnetic seal, or both are supporting uses together;
The top of described valve body is inlet point, and bottom is discharging opening;
Described impeller feed bin is in magnetic sealing device, and what impeller feed bin adopted is flexible sealing, or the sealing band sealing arrangement of positiver sealing; The sealing band sealing arrangement of magnetic sealing device and impeller feed bin can play sealing function to the sticking part of magnetic sealing device and impeller feed bin.
Described side cover is fixed on the both sides of valve body by screw, and center and the bearing of side cover are connected to one;
Described valve shaft is in the center of impeller feed bin, and valve shaft and impeller feed bin are fixed together; The two ends of valve shaft are by bearings, and one end of valve shaft is sealed in side cover, and the other end extends outside valve body and is connected to change speed gear box and motor;
Start motor, motor drives valve shaft, impeller feed bin to rotate by change speed gear box, and impeller feed bin rotary motion works.
The workflow of magnetic seal discharge gate of the present invention is: when using work, the inlet point of valve body is connected to feeding warehouse, and bottom discharge mouth is connected to discharging bin; Start motor C, motor C drives the work of valve shaft, impeller feed bin rotary motion by change speed gear box B, and material is just rotarily driven into from the inlet point above valve body by impeller feed bin, discharges from the discharging opening below valve body; Utilize the binding site of the sealing band sealing arrangement of magnetic sealing device, impeller feed bin to magnetic sealing device and impeller feed bin to play sealing function, its sealing air-tightness is high, and gas leakage property is few.
The present invention has following beneficial effect compared with existing discharge gate: magnetic seal discharge gate adopts magnetic sealing device as main seal, and the sealing band sealing arrangement of impeller feed bin is auxiliary seal; The sealing air-tightness of magnetic seal discharge gate is high, and air leakage is few; Wearing and tearing between impeller feed bin and magnetic sealing device are few, reduce operating power consumption, extend the service life of discharge gate; Magnetic seal discharge gate structure is simple, can adjust according to the operation pressure of system, and external condition restriction is few, practical, applied range.
