Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An automatic magnetic screening device comprising:
the screening box is used for containing the magnetic microspheres to be screened;
and the magnetic separation device is used for separating the magnetic microspheres with the magnetic content equal to or greater than a set value from the magnetic microspheres with the magnetic content lower than the set value by utilizing magnetic force.
The invention uses magnetic force to separate out the magnetic microsphere which is not in accordance with the requirement simply and easily.
In practical application, the magnetic separation device comprises a lifting device and a driving device for driving the lifting device to operate, the lifting device is provided with a magnetic component, and the lifting device repeatedly adsorbs magnetic microspheres with the magnetic content equal to or greater than a set value from the screening box and separates the magnetic microspheres from the magnetic microspheres.
As shown in fig. 1, in specific implementation, the lifting device may adopt the following technical solutions, including:
at least two rollers, in the example of fig. 1 two rollers 32 and 31, at least one of which is a driving wheel, for example roller 32 is a driving wheel and 31 is a driven wheel;
and a conveyor belt 33 which is wound around the rollers and driven by the rollers to rotate in a reciprocating manner, wherein the conveyor belt has magnetism.
In specific application, a connecting line between the axes of the different rollers forms an acute angle with the horizontal direction. In fig. 1, the axis of the rollers 31 and 32 is connected at about 45 ° to the horizontal, and this degree can be determined according to the magnitude of the magnetic force and other requirements, such as the size of the classifying box 1 and the size of the raw material chamber 2.
In order to avoid direct contact of the magnetic microspheres with the conveyor belt 33, the automatic magnetic screening device further comprises a partition (comprising three interconnected or integrated sections of partition 51/52/53 in the example of fig. 1) arranged in the screening box 1, which partition divides the screening box 1 into at least the following two parts separated from each other by a leak:
the space enclosed by the lower surfaces of the partition boards is an equipment chamber 3 for placing the lifting device;
the part of the partition corresponding to the conveyor belt 33 between the upper edges of the rollers 32 and 31 is arranged in parallel with the partition (namely, the part of the partition marked with the reference number 51 in fig. 1), and the gap between the partition and the conveyor belt enables the magnetism of the conveyor belt to still pull the magnetic microspheres with the magnetic content equal to or greater than a set value to move upwards along the partition; this ensures both the magnetic attraction of the magnetic force of the conveyor belt 33 to the magnetic microspheres and the isolation of the magnetic microspheres from the lifting device. The independent material chamber 2 can contain liquid, and the microspheres to be separated are placed in the liquid, so that the protection of the magnetic microspheres can be met.
A raw material chamber 2 is enclosed between the part of the partition board corresponding to the conveying belt between the upper edges of the rollers and the part of the box body of the screening box, and the raw material chamber 2 forms a container for magnetic microspheres to be separated.
In some embodiments, the partition extends from the high end of the portion of the partition parallel to the conveyor belt 33 to the bottom of the sieving box (the partition corresponds to the portion designated by reference numeral 52) around the uppermost roller, and forms a sorting chamber 4 together with a part of the box body of the sieving box, so as to store the magnetic microspheres screened with the magnetic content equal to or greater than the set value.
In some embodiments, the automatic magnetic screening device is further provided with a stirring device 7, and a stirring working part of the stirring device 7 extends into the raw material chamber. The stirring means agitates the liquid and the magnetic microspheres in the raw material chamber 2 to move them, so that all the magnetic microspheres have an opportunity to be attracted by the magnetic force of the conveyor belt 33, thereby improving the efficiency and rate of separation.
In practical application, the conveyor belt is embedded with magnetic materials at intervals, or the surface of the conveyor belt is coated with a layer of magnetic material. In addition, the gap between the partition plate 51 and the conveyor belt 33 can be adjusted to adjust the influence of the magnetic force on the magnetic microspheres.
In some embodiments, the stirring device may employ a solution including an air pump and an air nozzle extending into the raw material chamber, and air is used to stir the magnetic microspheres in the raw material chamber 2.
In some embodiments, the automatic magnetic sieving device is further provided with a blanking device, which comprises a group of air nozzles 6 arranged above the high end of the part of the partition plate parallel to the conveyor belt, and is used for blowing off the magnetic microspheres moving to the highest position of the partition plate.
In some embodiments, the lowermost portion of the partition 51 extends upwardly and connects to the side walls of the sifting box, see the portion of partition 53 in FIG. 1, and this design is clever so that the lowermost portion of the feed chamber 2 is located in the region of the partition 51 so that the magnetic microspheres in the feed chamber 2 at their lowermost position are also in the region of being acted upon by the magnetic force.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and similar parts between the embodiments are referred to each other. The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
