Description
Technical field
The invention belongs to explosive wastewater feeding technique fields, are related to a kind of powder explosive wastewater weight-loss type self-conveyor feed, specifically
It is related to a kind of explosive wastewater powder with inflammable and explosive feature that can be suitable for easily entering Bearing gaps generation friction danger
End charging self-conveyor feed.
Background technology
Weight-loss type self-conveyor feed is one of the most frequently used equipment of powder material feed, is being frequently necessary to accurate quantification charging
Chemical industry and pharmaceuticals industry application it is particularly extensive.With the development of self-conveyor feed, extend various forms of chargers, including
Single-screw charger and double helix charger, wherein double helix charger to the feeding quantity of powder material can from several litres per hour to
Thousands of liter per hour, charging precision can reach 0.5%.A branch of the explosive wastewater industry as chemical industry, screw feeding
Machine is also in the quantifying feed for being gradually introduced into powder explosive wastewater material.Due to the inflammable and explosive characteristic of explosive wastewater material, at present
Weight-loss type self-conveyor feed is chiefly used in the quantifying feed of the non-flammable explosive material such as aluminium powder of the sector.For explosive wastewater powder,
In view of the shaft gap that powder can enter self-conveyor feed causes friction explosion and self-conveyor feed spiral part and charging
The collision of trough wall surface squeezes generation spark, and the application of weight-loss type self-conveyor feed is subject to certain restrictions.
In improving the performance of screw feeders, having multidigit researcher to change is found to the retrieval of existing technical literature
Into.Chinese utility model patent CN 2883266Y disclose a kind of variable cross-section self-conveyor feed, can improve the uniform of charging
Property；Chinese invention patent CN 1986359A disclose a kind of Shaftless spiral blade double helix charger, can realize bulk, easily
Wind effective charging of material；Chinese utility model patent CN 201046859Y disclose a kind of spiral of up big and down small hopper
Charger can effectively avoid the fluffy material of wet feed.For the formal open source literature consulted, at present for self-conveyor feed performance
Improvement be concentrated mainly on extension charging type and improve charging stability in terms of；It is most typical to change in terms of safety in utilization
It is that the dual-seal of axle envelope aerating envelope, axle envelope is used effectively powder particle can be organized to enter bearing in spindle portion into measure
Gap, sealing gland avoid diffusion mobility of the superfines to Bearing gaps by forming micro-positive pressure.Due to powder material and shaft
Point be in direct contact, sealing gland will necessarily be with the generation of dust, and according to actual use experience, this mode is being accumulated over a long period
There are still the phenomenon that deposition material, be unfavorable for the timely of Bearing gaps surface deposited powder in Bearing gaps in charging work
Cleaning.
Invention content
For overcome the deficiencies in the prior art, the present invention provides a kind of spiral shell that can be applied to powder explosive wastewater and feed safely
Revolve charger.
A kind of powder explosive wastewater weight-loss type self-conveyor feed provided by the invention, by motor, bearing housing, blanking groove, hopper,
Screw rod, feed well, electronic scale, dustproof cover, hold-down support composition.
Blanking groove is equipped with discharge port.
Hopper is equipped with feed inlet.
Feed well is connected between hopper and blanking groove.
Bearing housing is connected between motor and screw rod.
The integral freely-supported of motor, bearing housing, blanking groove, hopper, screw rod, feed well is on electronic scale.
Electronic scale is mounted on hold-down support.
The motor, bearing housing are in the side of blanking groove, and hopper is in the other side of blanking groove.
The material of the screw rod and feed well uses the copper alloy of the 30%-42% of mass fraction containing zinc in copper matrix.
Compared with prior art, it is an advantage of the invention that：It is weightless in powder explosive wastewater utmostly to promote self-conveyor feed
Safety in formula charging application.The realization of the advantage is to rely on following both sides technological innovation：(1) metal is easy to happen to touch
The screw rod and feed well hit uses Cu alloy material, avoids metal bump from generating spark, fundamentally prevents charging technology mistake
Spark causes the burning and explosion of explosive wastewater material in journey；(2) bearing housing and hopper are placed in blanking groove both sides, avoid bearing
Case is in direct contact with explosive wastewater material, fundamentally prevent screw rod reaction force granular material is squeezed into Bearing gaps and
The friction of explosive wastewater powder is caused to fire.
Description of the drawings
Invention is further described in detail with reference to the accompanying drawings and detailed description：
Fig. 1 is a kind of powder explosive wastewater weight-loss type self-conveyor feed main structure diagram of the present invention.
Fig. 2 is a kind of powder explosive wastewater weight-loss type self-conveyor feed overlooking structure diagram of the present invention.

Feed inlet, 10, discharge port, 11, hold-down support, 12, material to be added.
Specific implementation mode
The present invention will be further described with specific implementation mode with reference to the accompanying drawings of the specification.
As depicted in figs. 1 and 2, a kind of powder explosive wastewater weight-loss type self-conveyor feed of the invention, including motor 1, bearing
Case 2, blanking groove 3, hopper 4, screw rod 5, feed well 6, electronic scale 7, dustproof cover 8, hold-down support 11.The transmission shaft of motor 1 passes through
Connection is keyed to 2 one end of bearing housing；2 other end of bearing housing and 3 one end of blanking groove are connected by screw；3 other end of blanking groove
It is connected with feed well 6, feed well 6 is connected with hopper 4 simultaneously；Blanking groove 3, feed well 6 and hopper 4 are a welding or cast whole
Body；Screw rod 5 is with the reduction gearing in bearing housing 2 by connecting key connection；Dustproof cover 8 covers the upper end opening in blanking groove 3；Motor
1, bearing housing 2, blanking groove 3, hopper 4, screw rod 5, feed well 6, dustproof cover 8 constitute self-conveyor feed main body；Self-conveyor feed is whole
Body is connected to by freely-supported on electronic scale 7, and freely-supported connection needs to ensure that self-conveyor feed main body center of gravity is fallen on electronic scale 7；Spiral shell
It revolves charger main body and electronic scale 7 constitutes weight-loss type self-conveyor feed；Weight-loss type self-conveyor feed is fixed by hold-down support 11
On work top.
The material of the screw rod 5 and feed well 6 uses the copper of the 30%-42% of mass fraction containing zinc in copper matrix to close
Gold.
The cardinal principle of the present invention is that material 12 to be added is added from feed inlet 9 in hopper 4, by controlling the rotating speed of motor 1,
Material 12 to be added is pulled in blanking groove 3 by screw rod 5 by feed well 6, and material 12 to be added is flowed out from the discharge port 10 of blanking groove 3；Electricity
Son claims 7 to realize weight-loss metering；Dust from flying during dustproof cover 8 prevents material 12 to be added from discharging.
Screw rod 5 and feed well 6 of the present invention use copper alloy, can not only realize the timely export of accumulation of static electricity, moreover it is possible to
The collision spark for preventing hardware generates；What is more important, the present invention use the side that screw rod 5 pulls out material 12 to be added
Formula, the entire movement locus of material 12 to be added are not all in direct contact with sound rotating part bearing housing 2, effectively avoid fire
Explosive powder enters the rotating part of bearing housing 2, the generation for fundamentally preventing friction to fire.
