Description
Technical field
The utility model relates to a kind of powder feeding device, relates to the powder feeding device of a kind of anti-airborne dust, even sub-material specifically.
Background technology
The feed arrangement of granular material is very general in the application of laboratory and industrial circle, mainly appears on the devices such as revolving the sieve that shakes, grinder, crusher, batch mixer, twin rollers.
In the powder material fill process, as be fed directly on next step corresponding parts, cause solid accumulation easily, equipment is caused damage.It is dispersed on next step corresponding parts is the problem that above various application apparatus faces jointly.Patent CN2504506 discloses a kind of system of even sub-material, and it mainly is to constitute one by an accumulator tank and a jig arm can comply with the equipment needs that cooperated, and carries out the feed arrangement that material replenishes, and can reach the purpose of even sub-material.But its structure more complicated, and the storing groove need be provided with motor to drive its rotation, the also corresponding raising of cost.
Because powder material very easily causes dust raising phenomenon, and environment is caused cooresponding pollution, in addition, some material is relatively more responsive for ambiance, should reduce contacting of ambiance and material as far as possible.Using at present more is that end face at hopper installs sweep-up pipe or dust-exhausting tube additional, and the dust of kicking up in the hopper is siphoned away, and reaches the effect of dedusting.But its additive incrementation dust collecting system, also have complex structure, the defective that cost increases.
The utility model content
The powder feeding device that the utility model provides, have sub-material evenly, anti-airborne dust is effective, be subjected to ambiance to influence advantages such as little, and is and simple in structure, productive costs is lower.
The technical solution of the utility model is as follows:
A kind of powder feeding device comprises hopper, inlet point, and the inlet point below is provided with the evenly distributing device of sub-material, and distributing device is set up on the hopper.This distributing device can be connected in the hopper in any feasible mode, and guarantees that this attaching parts can not hinder material and pass through.
Described distributing device can be top pyramidal structure up or narrow slit structure wide at the top and narrow at the bottom, to adapt to the needs of distinct device, such as for revolving the sieve that shakes, generally selects top pyramidal structure up for use; For twin rollers, generally select narrow slit structure wide at the top and narrow at the bottom for use, narrow slit structure herein comprises structure suitable for reading, that end opening flushes respectively, also comprises flexuose cross structure, can guarantee that the material input is unobstructed, keeps material to be uniformly dispersed by slit during output.
When described distributing device is up pyramidal structure of top, its upper surface can be provided with radially flow guide bar or the spill-strip of hoop.Flow guide bar can make the uniform one way or another of material flow, and to reach the purpose of even sub-material, also can be provided with hole or slit between flow guide bar, make distributing device under material be more evenly distributed, evenly disperse to periphery simultaneously.The spill-strip of hoop stops when material is arrived slightly, and before all directions did not reach evenly, material can not directly flow out distributing device or flow to next spill-strip, also can reach the purpose of even sub-material.
For twin rollers, distributing device can be narrow slit structure wide at the top and narrow at the bottom, and material enters through the last square opening of feed pipe from distributing device, flows out distributing device along narrow thin following square opening, can make material be the linear centre portion that enters twin rollers uniformly.
The effect of distributing device also is embodied in and can effectively reduces airborne dust and overflow inlet point, avoids environmental pollution, and makes the material to the ambiance sensitivity be protected.
Can be provided with on the described inlet point and stretch into the feed pipe that hopper in-to-in, cross-sectional area diminish gradually from top to bottom, the lower end of feed pipe is positioned at the top of distributing device, and the upper end of feed pipe can project to outside the inlet point.Feed pipe can be pipe or other shapes, and feed pipe can be a hard tube, but is preferably flexible tube.Feed pipe can prevent further that airborne dust from overflowing inlet point.
The utlity model has following advantage:
1. powder feeding device of the present utility model by distributing device is set, evenly disperses material; Big, the infringement of avoiding the material local accumulation that equipment is caused of working area after the material charging;
2. powder feeding device of the present utility model, distributing device is located at the inlet point below, can play certain barrier effect to airborne dust, in addition, inlet point is provided with and stretches into the feed pipe that hopper in-to-in, cross-sectional area diminish gradually from top to bottom, can prevent further that dust from overflowing from inlet point; Simultaneously, more than double obstruct also can reduce ambiance and enter hopper, thereby the protection material;
3. powder feeding device of the present utility model, simple in structure, productive costs is lower.

The specific embodiment
To help to understand the utility model by following embodiment and accompanying drawing, but not limit content of the present utility model.
A kind of powder feeding device as shown in Figure 1, comprises hopper 1, inlet point 2, and inlet point 2 belows are provided with the evenly distributing device 4 of sub-material, and distributing device 4 is set up in the hopper 1.This distributing device 4 can be connected in the hopper 1 in any feasible mode, and guarantees that this attaching parts can not hinder material and pass through.
Described distributing device 4 is top pyramidal structure up or two kinds of embodiments of narrow slit structure wide at the top and narrow at the bottom, to adapt to the needs of distinct device, for revolving the sieve that shakes, selects top pyramidal structure up for use; For twin rollers, select narrow slit structure wide at the top and narrow at the bottom for use.
