Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b): referring to fig. 1-4, a nano titanium dioxide powder particle screening device for a nano coating includes a positioning seat 1, a detachable screening frame 2 is installed on the inner side of the positioning seat 1 through a chute, a cross beam 3 is fixedly connected on the inner side of the positioning seat 1 and above the positioning seat, a motor 4 is fixedly installed on the top of the cross beam 3, and a rotating shaft 5 is installed on an output spindle of the motor 4.

Be provided with the pressure cover 6 on the axis of rotation 5, the outside of pressure cover 6 is fixed with the stirring strip 7 of a plurality of reposition of redundant personnel nanometer titanium dioxide powder particles, when nanometer titanium dioxide powder particle screening, can be with the inside of the leading-in screening frame 2 of nanometer titanium dioxide powder particle of treating the screening by the top, the inside sieve mesh of screening frame 2 can be selected and is not conform to the requirement nanometer titanium dioxide powder particle.

Control motor 4 operation, motor 4 is PMSM, the rotational speed is 110/min, under motor 4's output effort, can drive and press cover 6 to drive stirring strip 7 rotatory, stirring strip 7 is located the inner chamber rotation of screening frame 2, can shunt a large amount of leading-in materials inside screening frame 2, furthermore, can make accumulational material evenly shift the inboard that sieves frame 2 under the rotation effect that is located its inside stirring strip 7, have the reposition of redundant personnel effect to accumulational material, make the material shifted the screening fast. Meanwhile, the rotating thrust generated by the rotation of the stirring strips 7 can accelerate the falling speed of the screened materials on the inner wall of the screening frame 2, and effectively avoid the phenomenon of mass accumulation caused by the falling of a large amount of materials.

As shown in fig. 1 and 2, a limiting beam 8 is arranged on the inner side of the positioning seat 1, and an extending rod 9 is arranged at the center of the top of the limiting beam 8.

Extension rod 9 runs through in screening frame 2, and when screening frame 2 installed in the inboard of positioning seat 1, the surface of spacing roof beam 8 of bottom laminating of screening frame 2. Extension rod 9 and screening frame 2 be connected, can keep the stability of screening frame 2, combine the recess that 1 inboard of positioning seat was seted up to be connected screening frame 2, can avoid screening frame 2 to be installed in the inboard of positioning seat 1, to be strikeed the phenomenon of squinting by the material when screening the work.

As shown in fig. 3 and 4, a supporting beam 10 is fixedly connected to the inner side of the positioning seat 1, a pair of inner fixing rods 11 is fixedly connected to the top of the supporting beam 10, and the side walls of the inner fixing rods 11 are provided with retractable balancing fixture blocks 12.

The inner fixing rod 11 penetrates through the limiting beam 8, when the screening frame 2 is installed on the inner side of the positioning seat 1, the balancing fixture block 12 abuts against the inner fixing rod 11, and the end part of the balancing fixture block 12 abuts against the surfaces of the limiting beam 8 and the supporting beam 10 respectively. The balance fixture block 12 supports the limiting beam 8 and the supporting beam 10 at opposite sides, so that the phenomenon of offset sliding of the limiting beam 8 is avoided, and the screening frame 2 is further kept stable.

As shown in fig. 4 and 5, the surfaces of the balancing fixture blocks 12 are all fixed with sliding rods 13, the side surfaces of the positioning seat 1 are all fixed with a pair of limiting strips 14, the sliding rods 13 penetrate through the limiting strips 14, the surfaces of the sliding rods 13 are fixed with compression springs 15, the compression springs 15 are located on the inner sides of the limiting strips 14, and the end flanges of the sliding rods 13 are attached to the surfaces of the limiting strips 14 in a natural state.

When the screening frame 2 needs to be disassembled, the sliding rod 13 needs to be stretched outside the limiting strip 14, the sliding rod 13 drives the balance clamping block 12 to be separated from the connection of the inner fixing rod 11, and at the moment, the compression spring 15 contracts. The limiting beam 8 losing the supporting force of the balancing fixture block 12 can slide downwards on the top of the supporting beam 10, and the connection of the screening frame 2 is released. At the same time, the extension rod 9 releases the connection to the screening frame 2.

The inclined screening frame 2 can enable the grooves formed in the inner sides of the positioning seats 1 at the two ends of the screening frame 2 to be inclined until the screening frame 2 is inclined to a certain degree and can be separated from the grooves, and the screening frame 2 is completely disassembled. Through this kind of installation dismantlement mode, have stronger practicality, can be convenient for dismantle the washing after the work is accomplished to screening frame 2, reduce the material of its surface and remain.

As shown in fig. 2 and 3, the pressing sleeve 6 penetrates the rotating shaft 5, and a placement groove 17 for accommodating the sliding of the pressing sleeve 6 is formed on the surface of the rotating shaft 5. Dismantle screening frame 2, make its in-process that breaks away from positioning seat 1, can hand the pressure cover 6, make it drive and mix 7 upper parts of the bodies, order about to mix 7 can rise and keep away from screening frame 2 of stirring, it is further to be convenient for the smooth dismantlement of screening frame 2 breaks away from.

It is worth mentioning that the pressing sleeve 6 is tightly attached to the inner wall of the placing groove 17, and the pressing sleeve can slide upwards only by manual force application, so that the pressing sleeve 6 is prevented from sliding easily in the placing groove 17, and the stability of the pressing sleeve 6 in rotation of the stirring bar 7 is guaranteed. Meanwhile, the shaking phenomenon when the pressing sleeve 6 drives the stirring strip 7 to rotate is reduced.

As shown in fig. 4, a material receiving barrel 16 is arranged at the bottom of the inner side of the positioning seat 1. The purpose of the removable collecting bucket 16 is to collect the material filtered by the screening rack 2, so that the material can be transported in a centralized manner.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
