Description

Technical Field

[0001] The invention belongs to the technical field of powder processing, and in particular relates to a powder deagglomeration and dispersion device. Background Art

[0002] Powder deagglomeration and dispersion equipment is a machine used for powder processing. Its principle is known from the existing technology. Generally, the agglomerated or lumped materials are fed into the dispersion chamber through a screw feeder, and the materials are impacted and sheared by the high-speed rotating rotor to crush and restore the materials. The dispersed materials are transported to the material collection area by the rising air flow, collected by the cyclone collector and the pulse dust collector, and the purified air is discharged by the induced draft fan.

[0003] At present, when the powder material is in the process of deagglomeration, the deagglomerated powder is generally first brought into the filter by the airflow, and then the powder passing through the filter is collected by the cyclone collector. That is, if you want powder of about 1000 mesh, use a 1000-mesh filter to collect the powder. Powders smaller than 1000 mesh can pass through the filter, and powders larger than 1000 mesh are blocked by the filter and return to the deagglomeration cylinder to continue deagglomeration and dispersion. However, we found a problem during use. During the deagglomeration process, the rising airflow will take away the powder, and the gas will also take away a part of the powder that does not meet the filtering conditions, that is, the powder larger than the filter diameter. Due to the upward thrust of the gas, the powder larger than the filter diameter will fit the filter. This situation will directly lead to filter blockage, affecting the collection efficiency of powder that meets the filtering conditions. Summary of the invention

[0004] The purpose of the present invention is to provide a powder deagglomeration and dispersion device, and its purpose is to reduce the efficiency of filter screen clogging during powder deagglomeration and dispersion treatment.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a powder deagglomeration and disintegration device, comprising a base and a controller, an air pump and a deagglomeration cylinder are arranged on the base, and the air outlet end of the air pump transports gas to the bottom of the deagglomeration cylinder through an air pipe;

[0013] Specifically, the filter assembly includes a circular filter No. 1 and a circular filter No. 2, the mesh diameter of the circular filter No. 1 is smaller than the mesh diameter of the circular filter No. 2, the circular filter No. 1 and the circular filter No. 2 are fixedly connected by a circular elastic band, and the output shaft of the rotating motor passes through the circular filter No. 1 and the circular filter No. 2, and is fixed to the circular filter No. 1 and the circular filter No. 2.

[0014] Specifically, a grinding ball is provided between the No. 1 circular filter screen and the No. 2 circular filter screen, there are more than one grinding ball, and the grinding ball is located in the circular elastic band.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] In order to solve the problems raised in the background technology, the present invention designs a powder deagglomeration and dispersion device, the main innovation of which is the improvement of the filter screen, which can reduce the probability of filter screen clogging, thereby improving the efficiency of powder collection after deagglomeration and dispersion, as follows:

[0030] like Figure 1-4 As shown, the powder deagglomeration and disintegration equipment comprises a base 1 and a controller, an air pump 2 and a deagglomeration cylinder 3 are arranged on the base 1, the air pump 2 is started and stopped by the controller, the air outlet end of the air pump 2 delivers gas to the bottom of the deagglomeration cylinder 3 through the air pipe 21, a feed port 4 is provided on the deagglomeration cylinder 3, a deagglomeration motor 5 is arranged at the bottom of the deagglomeration cylinder 3, the deagglomeration motor 5 is controlled by the controller, a deagglomeration rod 51 is fixed on the output shaft of the deagglomeration motor 5, a grinding roller 52 is fixed on the deagglomeration rod 51, a scraper 54 is arranged at the bottom of the deagglomeration rod 51, a grinding ring 53 is fixed on the side wall of the deagglomeration cylinder 3, and the grinding roller 52 and the grinding ring 53 cooperate to deagglomerate and disperse the powder;

[0031] Furthermore, different from the prior art, a rotating motor 6 is provided inside the top of the depolymerization cylinder 3, the rotating motor 6 is controlled by a controller, the input end of the rotating motor 6 is fixed to the depolymerization cylinder 3, the output shaft is fixedly connected to a filter assembly, and a collecting pipe 7 is provided at the top of the depolymerization cylinder 3, and the collecting pipe 7 is connected to an external cyclone collector (not shown in the figure);

[0032] Further, the filter assembly includes a first circular filter screen 61 and a second circular filter screen 62, the mesh diameter of the first circular filter screen 61 is smaller than the mesh diameter of the second circular filter screen 62, the first circular filter screen 61 and the second circular filter screen 62 are fixedly connected by a circular elastic band 63, and the output shaft of the rotating motor 6 passes through the first circular filter screen 61 and the second circular filter screen 62, and is fixed to the first circular filter screen 61 and the second circular filter screen 62;

[0033] Generally speaking, when the powder is deagglomerated and dispersed, the deagglomeration motor 5 is started by the controller to rotate the grinding roller 52, and then the powder to be deagglomerated and dispersed is added through the feed port 4, and then the powder enters between the grinding roller 52 and the grinding ring 53. As the grinding roller 52 rotates, the powder between the grinding roller 52 and the grinding ring 53 is deagglomerated and dispersed, and then the powder that has not been dispersed is picked up again by the scraper 54 rotating at the bottom of the deagglomeration rod 51, and returns to the grinding roller 52 and the grinding ring 53 for re-deagglomeration and dispersion. Then, the air pump 2 is controlled by the controller to start, so that the airflow in the air pump 2 enters the deagglomeration cylinder 3 through the air pipe 21, and drives the deagglomerated and dispersed powder to move to the upper side of the deagglomeration cylinder 3;

[0034] It should be noted that the above is the working principle of the powder deagglomeration and dispersion equipment, which is the prior art and the present invention will not be described in detail here;

[0035] Next, the powder moving upward passes through the filter assembly, and then enters the collection pipe 7, and is collected by the external cyclone collector. Before the powder passes through the filter assembly, the controller first starts the rotating motor 6 to drive the filter assembly to rotate, that is, to drive the No. 1 circular filter 61 and the No. 2 circular filter 62 to rotate. When the deagglomerated and dispersed powder moves upward driven by the airflow, it first contacts the No. 2 circular filter 62. The powder that meets the filtering conditions of the No. 2 circular filter 62 passes through the No. 2 circular filter 62 and enters the No. 1 circular filter 61. Because the mesh diameter of the No. 1 circular filter 61 is smaller than that of the No. 2 circular filter, the powder that meets the filtering conditions of the No. 2 circular filter 62 enters the No. 1 circular filter 61. The circular filter screen 62 and then the No. 1 circular filter screen 61 can pass powders with smaller particle sizes, thereby improving the quality of the collected powder after the powder is deagglomerated and dispersed. At the same time, during the rotation of the No. 1 circular filter screen 61 and the No. 2 circular filter screen 62, the No. 1 circular filter screen 61 and the No. 2 circular filter screen 62 can be prevented from being blocked, thereby affecting the efficiency of powder collection. At the same time, the No. 1 circular filter screen 61 and the No. 2 circular filter screen 62 can collide with the upwardly moving powder during the rotation, such as the powder that cannot pass through the No. 2 circular filter screen 62, thereby further breaking up the powder and improving the powder breaking effect.

[0036] Furthermore, a grinding ball 64 is provided between the first circular filter screen 61 and the second circular filter screen 62 . There are more than one grinding ball 64 , and the grinding ball 64 is located in the circular elastic band 63 .

[0037] Specifically, after the powder passes through the No. 2 circular filter 62, it enters the circular elastic band 63 and contacts the grinding balls 64. As the No. 1 circular filter 61 and the No. 2 circular filter 62 rotate, the grinding balls 64 will collide with each other in a disordered manner, and the selected No. 1 circular filter 61 and the No. 2 circular filter 62 cooperate with each other, so that the powder can be further ground and dispersed, and the effect of powder deagglomeration can be further improved. At the same time, the grinding balls 64 can also collide with the No. 1 circular filter 61 and the No. 2 circular filter 62 during the collision process, so as to further prevent the filter assembly from being blocked.

[0038] It should be noted that the circular elastic band 63 in the present invention can be formed by rolling the strip elastic steel band into a circle, fixing the ends of the strip elastic steel band to form a circular elastic band 63, and then fixing the top end of the circular elastic band 63 to the No. 1 circular filter screen 61, and fixing the bottom end to the No. 2 circular filter screen 62.

[0039] Furthermore, the first circular filter screen 61 and the second circular filter screen 62 are detachably connected to the output shaft of the rotating motor 6;

[0040] By detachably connecting the No. 1 circular filter 61 and the No. 2 circular filter 62 to the output shaft of the rotating motor 6, when powders of different particle sizes are needed, the No. 1 circular filter 61 and the No. 2 circular filter 62 with different mesh diameters can be replaced. The specific detachable connection method can be bolt connection, clamping, etc.

[0041] Furthermore, the first circular filter screen 61 and the second circular filter screen 62 are both made of steel.

[0042] The first circular filter 61 and the second circular filter 62 are made of steel, which can increase the impact force on the powder when the first circular filter 61 and the second circular filter 62 rotate, and can crush the powder with a larger particle size, thereby improving the effect of powder deagglomeration and dispersion.

[0043] Furthermore, the grinding roller 52 and the grinding ring 53 are both made of wear-resistant materials. The use of wear-resistant materials reduces wear and has a longer service life.

[0044] Furthermore, the collecting tube 7 and the rotating motor 6 are not located in the same plane, thereby ensuring that the position of the rotating motor 6 does not affect the powder passing through the collecting tube 7 .

[0045] In summary, in the present invention, during the rotation of the No. 1 circular filter 61 and the No. 2 circular filter 62, the No. 1 circular filter 61 and the No. 2 circular filter 62 can be prevented from being blocked, thereby affecting the efficiency of powder collection. At the same time, during the rotation of the No. 1 circular filter 61 and the No. 2 circular filter 62, the powder moving upward can be hit, such as the powder that cannot pass through the No. 2 circular filter 62, so that the powder can be further dispersed, thereby improving the powder dispersion effect.

[0046] At the same time, after the powder passes through the No. 2 circular filter 62, it enters the circular elastic band 63 and contacts the grinding balls 64. As the grinding balls 64 rotate with the No. 1 circular filter 61 and the No. 2 circular filter 62, disordered collisions will occur between the grinding balls 64. The selected No. 1 circular filter 61 and the No. 2 circular filter 62 cooperate with each other, so that the powder can be further ground and dispersed, and the effect of powder deagglomeration is further improved. At the same time, the grinding balls 64 can also collide with the No. 1 circular filter 61 and the No. 2 circular filter 62 during the process of colliding with each other, thereby further preventing the filter assembly from being blocked.
