Description

A kind of powder automatic sampler

Technical field

The utility model relates to a kind of sampler, is specifically related to a kind of being used for from the device of powder or the automatic sampling of microgranular material process equipment.

Background technology

In occasions such as cement processing, need be to the powder detection of taking a sample of processing.Existing sampler generally includes hopper formula sampler, spiral sampler and reciprocating type sampler, and hopper formula sampler is got hopper motion sampling by driving, its complex structure, and volume is big, easily breaks down in bad working environment; Spiral sampler can be taken a sample continuously automatically, but owing to be to rotate by screw axis to drive the powder motion, stuck situation takes place easily.

Be directed to this, the applicant discloses a kind of powder automatic sampler in Chinese utility model patent CN2293063Y, adopt reciprocating type sampling, comprise housing, feed pipe, be provided with round table-like thief rod, electromagnet, spring, feed space and control circuit, thief rod is arranged in feed pipe, feed pipe is provided with charging hole, the thief rod afterbody is connected with ferromagnetic barred body, and electromagnet gets when electric, attracts the thief rod rollback to slide, compression spring, drive powder and enter feed space, during the electromagnet dead electricity, thief rod resets under the effect of spring, by the power on/off of control circuit control electromagnet, can realize continuously sampling automatically.

This structure does not need motor, thereby simple in structure, reliable in action, but,, exist porose between feed space and electromagnet space because thief rod mechanism need pack into from the feed space end, the powder of sampling can enter the electromagnet space from the hole when entering feed space, result in blockage and damage, on the other hand, because the general temperature of sampling machinery is higher, temperature can be passed to the electromagnet space through feed pipe, feed space, causes the damage of electromagnet easily and reduction of service life.

Summary of the invention

The utility model purpose provides a kind of powder automatic sampler, is keeping that existing sampler is simple in structure, on the basis of reliable in action characteristics, is preventing that powder from entering the electromagnet space, reducing the electromagnet space temperature, thereby prolong the serviceable life of sampler.

For achieving the above object, the technical solution adopted in the utility model is: a kind of powder automatic sampler, comprise electromagnet chamber, feed space, feed pipe and control device, feed space is between feed pipe and electromagnet chamber, the feed space below is provided with discharging opening, have charging hole on the described feed pipe, be provided with thief rod in the feed pipe, described electromagnet is indoor to be provided with electromagnet and to drive rod, driving rod fixedlys connected with thief rod one end, thief rod is located by spring, between described electromagnet chamber and feed space, is provided with isolation structure.

In the technique scheme, the feeding mechanism of described thief rod and driving bar construction is a prior art, thief rod is provided with a plurality of cone cylinder body shapes, bigger face is positioned at nearly feed space one end in each round platform, less face is positioned at nearly charging hole one end, pitch between round platform is generally between 10 millimeters to 50 millimeters, like this, when electromagnet attracted to drive rod, the bigger moving powder of wearing of round platform moved to the feed space direction, when spring resets thief rod, because the round platform table top has certain degree of tilt, resistance is less, can move between powder, to-and-fro movement is thus brought powder into feed space.

In the technique scheme, described isolation structure can comprise the dottle pin between electromagnet chamber and feed space, and the fixture that connects electromagnet chamber, dottle pin and feed space.

Further technical scheme, for improving isolation effect, described isolation structure comprises at least 1 spacer between electromagnet chamber and feed space, separates the dottle pin of electromagnet chamber, spacer, feed space, and the fixture that connects electromagnet chamber, dottle pin, spacer and feed space, spacer is provided with the hole, and thief rod passes through described hole with the connecting portion that drives rod.

In the technique scheme, can be provided with 1 to 4 described spacer, between electromagnet chamber and spacer, between adjacent spacer, be respectively equipped with described dottle pin between spacer and feed space.

In the technique scheme, described fixture is at least 3 standing screws, and corresponding every standing screw place is provided with one group of described dottle pin respectively.

Usually, for saving the space and obtaining better effects, described electromagnet is a solenoidal electromagnet, and described driving rod can be along sliding in the solenoid tube chamber.Certainly, promptly use general electromagnet, be provided with one in its place ahead and drive excellent slip tube chamber, also can realize the purpose of this utility model.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1. because the utility model is provided with isolation structure between electromagnet chamber and feed space, when powder enters feed space, the powder of blowing out from thief rod motion hole can drop in isolation structure on a small quantity, and can not enter in the electromagnet chamber, simultaneously, thief rod hole on the electromagnet chamber can do with the thief rod size match, further prevent entering of dust;

2. the setting of isolation structure simultaneously can be played heat insulation effect, when the very high powder of treatment temperature, high temperature will just can be delivered to the electromagnet chamber through fixture (screw rod), because the screw rod heat-transfer area is very little, the electromagnet room temperature is lower, is difficult for causing the damage of solenoid;

3. also be provided with spacer in the utility model, further strengthened isolating dust and heat insulation effect.
