Description
Technical field
The present invention relates to building materials field, in particular to a kind of dry-coal feeding device.
Background technology
In building materials paint making process, need to use various dry powder material, these dry powder materials are stored in different warehouses due to the difference of material, and in follow-up process, need the dry powder material different to these to mix.
In the production of dry powder, in the links such as transport, need to contact a large amount of metal objects, part metals parts are as nail, metal fillings etc. can enter wherein, these metal impurities very easily cause damage to the mixing page of mixer after entering the equipment such as mixer, cause damage, and dry powder material can not well mix by existing mixing system, cause final produced building materials coating quality not good, especially after powder from moisture caking, more easily there is the phenomenon that mixing is uneven, metal impurities in dry powder can not be removed again simultaneously, therefore metal impurities can be removed and can by uniform for dry powder blend feed arrangement by urgent need one in machinery equipment fill process.
Summary of the invention
The invention provides a kind of dry-coal feeding device, be intended to improve above-mentioned technical problem.
The present invention is achieved in that
A kind of dry-coal feeding device, comprise housing, stir roller and magnetic part, the two ends up and down of described housing arrange charging aperture and discharging opening respectively, describedly stir the middle part that roller is vertically arranged on described housing, the described upper end stirring roller is provided with tapered cap, lower end connects for driving the motor stirring roller and rotate, described motor is fixed on the inwall of described housing, described magnetic part is arranged on the inwall of described housing, the external diameter of roller is stirred, described magnetic part and describedly stir the passage being formed between roller and pass through for dry powder described in the diameter of the shade of described tapered cap is greater than.
The dry-coal feeding device that the technical program provides, operationally, motor action drives stirs roller rotation, when different types of dry powder raw material enters in housing from charging aperture, first drop in tapered cap, the surrounding inwall stirring roller thrown to by dry powder by the tapered cap of rotation, now, the magnetic part that inwall is arranged will contact in dry powder, and the metal fragment mixed in dry powder, metal impurities etc. are adsorbed by magnetic part, avoid these metal impurities to enter the device damage machines such as mixer.
Meanwhile, when different dry powder enters housing Inner, under the centrifugal action of tapered cap, the dry powder of the caking that makes moist is pulverized, and simultaneously different types of dry powder obtains preliminary mixing, these tentatively mixing dry powder enter can be mixed to get after in mixer more even.
The rotating speed of motor can carry out suitable setting, after avoiding metal impurities to be thrown away by tapered cap with inner walls and magnetic part surperficial sharp impacts, and make magnetic part not hold metal impurities.
Further, described magnetic part is made up of at least one group of permanent magnet, and the longitudinal cross-section of described permanent magnet is isosceles trapezoid, and the inwall of described housing is fixed in the thicker side of described permanent magnet, and described permanent magnet is arranged along the circumference of described inner walls.

Inner walls is fixed on the longer base of permanent magnet, housing and stir the passage formed between roller and reduced by permanent magnet, permanent magnet is positioned on the flow path of dry powder on the one hand, be beneficial to adsorbing metal impurity, on the other hand, the permanent magnet of isosceles trapezoid shape makes the flow path of dry powder change, form the dry powder circulation passage of reciprocal shape, be equivalent to the flow path extending dry powder, increase the time of contact of metal impurities and magnetic part, improve metal impurities by the probability adsorbed.
Magnetic part can be arranged to many groups, and specifically determine according to the height of housing and the size of magnetic part, further, described magnetic part is made up of two groups of permanent magnets, and described in two groups, permanent magnet is between the upper and lower every setting.
Further, described in stir on roller and be provided with the brim of a hat, described the brim of a hat one end be fixed on described in stir roller, the other end is tilted to down in the interval stretched into described in two groups between permanent magnet, forms the passage passed through for dry powder between the described the brim of a hat and described housing.
The interval formed between two groups of permanent magnets is from longitudinal cross-section, also be an isosceles trapezoid, this position arranges a brim of a hat, when in the process that dry powder drops from top to bottom, contact with the brim of a hat, dry powder is flung outward out the interval entered between two groups of permanent magnets, and drops on the permanent magnet below being positioned at, and further increases metal impurities by the probability adsorbed.
In the process that dry powder falls from top to bottom simultaneously, first dish out on the permanent magnet of top through tapered cap, then fall on the brim of a hat along this permanent magnet, thrown the permanent magnet surfaces to below by the brim of a hat thereafter.The path of whole whereabouts is reciprocal shape, substantially prolongs dry powder falls to discharging opening time from charging aperture, increases it by the probability adsorbed.
Dry powder is normally stored in warehouse, but due to reasons such as air humiditys, may there is the phenomenon of the caking that makes moist.These cakings are unfavorable for even for different types of dry powder blend.
Further, the outer wall stirring roller described in is evenly provided with multiple double wedge for pulverizing dry powder caking.
Double wedge rotates with stirring roller rotation, and in dry powder dropping process, the dry powder of caking can be broken up granulating by the double wedge of rotation, convenient that dry powder blend is even.
Further, also comprise motor fixing seat, described motor fixing seat is the reservoir body of one end open, stir described in described motor fixing seat is positioned at below roller, the lower end of roller is stirred described in described reservoir body stretches into, described motor fixing seat is fixed on the inwall of described housing, and described motor is fixed in described reservoir body.
Motor is arranged on the below stirring roller, because dry powder can fly away, may affect machine operation once enter in motor everywhere, by the reservoir body of fixed electrical machinery being stretched into the lower end stirring roller, being equivalent to whole motor to cover, preventing dry powder from entering motor.
Further, described in stir the lower end closed of roller, described in stir roller lower end be provided with the projection of ring-type, described projection along described in stir the outer wall of roller circumference surround a groove, described reservoir body stretches in described groove.
Further, described tapered cap is provided with fin, described fin is positioned at the upper surface of described tapered cap.
After fin is set, is conducive to tapered cap and dry powder dished out, dry powder is thrown out of farther.Such dry powder is closer to magnetic part in the process of dropping, and the metal impurities be mingled in wherein can more easily be adsorbed by magnetic part, and fin also can play and break up dry powder caking simultaneously.
Further, described fin is five, and described fin is arranged along the radial direction of the conical surface.
Further, described fin is five, and described fin is arc.
Fin can also be arranged to other forms, and quantity also can increase accordingly or reduce.
The invention has the beneficial effects as follows: dry-coal feeding device provided by the invention stirs roller by what arrange rotation, when dry powder enters, by the tapered cap of stirring on roller, dry powder is thrown toward the magnetic part place on housing, not only dry powder caking can be broken up, the metal impurities absorption mixed in dry powder can also be fallen, avoid these metal impurities to damage machinery equipment, whole apparatus design is simple to operate, is beneficial to popularization.
