[0002] Photocatalytic coating is a functional coating that contains photocatalysts. Photocatalysts are substances that can produce catalytic effects under the irradiation of light. These coatings can use light energy to drive chemical reactions to achieve a variety of functions, such as decomposing organic matter, sterilizing, and self-cleaning. Photocatalytic coatings have broad application prospects in the fields of environmental protection and construction. The quality of its raw materials directly affects the performance of the coating. During the procurement and storage of raw materials, some impurities are often mixed in, such as solid impurities with large particles, dust, fibers, etc. If these impurities are not removed, the coating will have problems such as uneven surface, reduced adhesion, and reduced photocatalytic effect during the coating process.

[0003] At present, the existing raw material screening and impurity removal equipment for coating processing screens the impurities in the raw materials through the filter during the powder processing process.

Therefore, when making, the staff first pours the powdered raw materials into the inside of the screening barrel, and at the same time, the staff starts the motor so that the output end of the motor drives the shaft to rotate in the screening component. Since the shaft is arranged at the axis of the receiving disk, the rotating shaft drives the accumulated powdered raw materials to improve the fluidity of the powdered raw materials. At this time, the raw materials are filtered along the receiving disk to the grinding disk below, so that the impurities in the raw materials are separated from the powdered raw materials after filtering. The rotating shaft drives the grinding rotor to rotate on the grinding disk to grind the powdered raw materials cast out of the screen to make the raw materials more delicate, and then the raw materials after grinding fall into the receiving bottom support, and the agglomerated raw materials are broken up by the rotating dispersing component.

At this time, the rotating shaft rotates at the axis of the receiving plate, so that the axis of the receiving plate is in an active state, and the powder raw material accumulated on the receiving plate slides continuously due to the activity, so as to avoid the accumulation of raw materials in the receiving plate when they are introduced, affecting the screening efficiency.

At this time, the collar drives the receiving arc piece to rotate under the grinding disc and contacts with the falling powder raw materials to cushion the falling powder, so that the powder raw materials slide downward along the receiving arc piece, thereby reducing the dust generated when the powder raw materials fall.

[0020] 2. The raw material screening and impurity removal equipment for processing photocatalytic coatings drives the bending rod to rotate in the material receiving bottom support through the material receiving arc piece. The raw materials stored and accumulated in the screening barrel are moved by multiple sets of elastic paddles to break up the raw materials that have agglomerated during grinding and rolling, while avoiding excessive accumulation of powdered raw materials after screening and exporting, causing blockage under the grinding disc.

[0021] 3. The raw material screening and impurity removal equipment for processing the photocatalytic coating is set by the staff starting the motor. The motor drives the dispersion component, the turntable and the grinding block to rotate. Then the staff pours the powder raw materials into the screening barrel. The powder raw materials are accumulated in the receiving tray. At this time, the rotating shaft rotates at the axis of the receiving tray, so that the axis of the receiving tray is in an active state. The powder raw materials accumulated on the receiving tray are continuously slid by the activity to avoid accumulation of raw materials in the receiving tray when they are introduced, affecting the screening efficiency.

[0022] 4. The raw material screening and impurity removal equipment for processing photocatalytic coatings is that the raw materials are screened through the receiving plate and then fall onto the top of the inclined pad.

[0023] 5. The raw material screening and impurity removal equipment for processing the photocatalytic coating has a raised pad set at the center of the receiving plate and is sleeved on the surface of the shaft. When the powdered raw material is poured into the filter plate, the powdered raw material is screened along the discharge hole to the inclined pad below. The impurities in the raw material cannot be screened out from the discharge hole. The impurities slide along the inclined filter plate to the side of the raised pad, so that the screened impurities gather at the connection between the filter plate and the raised pad, so as to facilitate the collection of the screened impurities and prevent the impurities from blocking the discharge hole.

Therefore, when making the coatings, the staff first pours the powdered raw materials into the screening barrel 2, and at the same time, the staff starts the motor 1, so that The output end of the motor 1 drives the shaft 41 to rotate in the screening component 7. Since the shaft 41 is arranged at the axis of the receiving tray 71, the rotating shaft 41 drives the accumulated powder raw materials to improve the fluidity of the powder raw materials. At this time, the raw materials are filtered along the receiving tray 71 to the grinding disk 73 below, so that the impurities in the raw materials are separated from the powder raw materials after filtration. The rotating shaft drives the grinding rotor 72 to rotate on the grinding disk 73, selects the thrown powder raw materials for grinding, so that the raw materials are finer, and then the raw materials after grinding fall into the receiving bottom support 5, and the ground agglomerated raw materials are dispersed by the rotating dispersion component 4.

[0039] The second embodiment is based on the first embodiment. Figures 3 to 6 As shown, the screening component 7 includes a receiving plate 71, which is fixedly installed inside the cavity of the screening barrel 2. A grinding plate 73 is arranged below the receiving plate 71, and both the receiving plate 71 and the grinding plate 73 penetrate the screening barrel 2 and extend to both sides of the outer surface of the frame 3.

Then the staff pours the powder raw material into the screening barrel 2, and the powder raw material accumulates in the receiving plate 71. At this time, the rotating shaft 41 rotates at the axis of the receiving plate 71, so that the axis of the receiving plate 71 is in an active state, and the powder raw material accumulated on the receiving plate 71 is continuously slid by the activity, so as to avoid the accumulation of raw materials in the receiving plate 71 when the raw materials are introduced, affecting the screening efficiency.

After the raw material is screened by the receiving plate 71, it falls onto the inclined pad 74. At this time, the rotating shaft 41 drives the rotating seat 75 and the grinding rotary block 72 to rotate on the surface of the grinding disc 73. The raw material above the inclined pad 74 is thrown outwards by the rotating centrifugal force, and slides between the grinding disc 73 and the grinding rotary block 72 according to the shape of the grinding disc 73, and is rotated and ground by the grinding rotary block 72 to form a relatively fine powder raw material.

[0041] The receiving plate 71 includes a protruding pad 712, which is sleeved on the outer surface of the shaft 41. A filter plate 713 is fixedly mounted on the outer surface of the protruding pad 712. A material discharge hole 711 is opened on the surface of the filter plate 713. First clamping blocks 714 are fixedly mounted on both sides of the outer surface of the filter plate 713. First connecting blocks 715 are fixedly mounted on the outer surface of the first clamping blocks 714. The protruding pad 712 arranged at the center of the receiving plate 71 is sleeved on the surface of the shaft 41. When the powder raw material is poured into the filter plate 713, the powder raw material is screened along the material discharge hole 711 to the inclined pad 74 below. Impurities in the raw material cannot be screened out from the material discharge hole 711. The impurities slide along the inclined filter plate 713 to one side of the protruding pad 712, so that the screened impurities gather at the connection between the filter plate 713 and the protruding pad 712, so as to facilitate the collection of the screened impurities and prevent the impurities from blocking the material discharge hole 711.

[0042] The grinding disc 73 includes an arc disc 731, which is arranged below the receiving disc 71 and sleeved below the outer surface of the shaft 41. An extrusion hole 732 is opened on the surface of the arc disc 731. Second clamping blocks 734 are fixedly installed on both sides of the outer surface of the arc disc 731, and second connecting blocks 733 are fixedly installed on the outer surface of the second clamping blocks 734. After preliminary screening, some powdered raw materials fall above the inclined pad 74, and the inclined pad 74 rotates on the outer side of the shaft 41 with the rotating seat 75 and the grinding rotating block 72. At this time, the powdered raw materials on the inclined pad 74 are thrown outward under the influence of centrifugal force and slide downward along the gap between the arc disc 731 and the grinding rotating block 72. At this time, the rotating grinding rotating block 72 crushes and grinds the raw materials, making the powdered raw materials more delicate and then sifted out from the extrusion hole 732 to improve the fineness of the raw materials.

[0043] The first connecting block 715 and the second connecting block 733 both penetrate the screening barrel 2 and extend to the interior of the frame 3 , and the first connecting block 715 and the second connecting block 733 are fixedly connected to the frame 3 .

[0045] The third embodiment is based on the first and second embodiments. Figures 7 to 9As shown, the dispersion assembly 4 includes a shaft 41, a collar 45 is fixedly installed at the bottom of the shaft 41, an extension rod 43 is fixedly installed inside the collar 45, a positioning ring 46 is fixedly installed at the bottom of the extension rod 43, and a material receiving arc piece 42 is fixedly installed on the outer surface of the collar 45. Four material receiving arc pieces 42 are provided, and the four material receiving arc pieces 42 are distributed in a circular shape on the surface of the collar 45. The staff starts the motor 1 so that the output end of the motor 1 drives the shaft 41 to rotate. At this time, the collar 45 drives the material receiving arc piece 42 to rotate under the grinding disc 73 and contact with the falling powder raw material to buffer the falling powder, so that the powder raw material slides downward along the material receiving arc piece 42, thereby reducing the dust generated when the powder raw material falls.

[0046] The shaft rod 41 passes through the screening assembly 7 and extends to the middle of the top of the frame 3 . The shaft rod 41 is fixedly connected to the output end of the motor 1 . Dispersion racks 44 are fixedly installed on both sides of the outer surface of the material receiving arc piece 42 . The dispersion racks 44 are fixedly connected to the positioning ring 46 .

[0047] The dispersion rack 44 includes a bending rod 441, and a fitting block 443 is fixedly installed on the surface of the bending rod 441 near the positioning ring 46. The fitting block 443 is fixedly connected to the positioning ring 46. A clamping groove 442 is provided on the surface of the bending rod 441 away from the fitting block 443. The clamping groove 442 is clamped on both sides of the outer surface of the material receiving arc piece 42. The material receiving arc piece 42 drives the bending rod 441 to rotate in the material receiving bottom support 5, and the raw materials stored and accumulated in the screening barrel 2 are moved by multiple groups of elastic paddles 444 to break up the raw materials agglomerated during grinding and rolling, and at the same time, avoid excessive accumulation of powder raw materials after screening and exporting, causing blockage below the grinding disc 73.

[0048] A fixing block 445 is fixedly installed on one side of the outer surface of the bending rod 441. The fixing blocks 445 are evenly arranged on the surface of the bending rod 441. An elastic paddle 444 is fixedly installed on the bottom of the fixing block 445. The elastic paddle 444 is frictionally adapted to the material connection base 5.

[0049] During use, when making the photocatalytic coating, the staff needs to screen and remove impurities from the powdered raw materials, and grind the powdered raw materials to make the raw materials finer during the production of the coating. Therefore, during the production, the staff first pours the powdered raw materials into the screening barrel 2, and at the same time, the staff starts the motor 1, so that the output end of the motor 1 drives the shaft 41 to rotate in the screening component 7. Since the shaft 41 is arranged at the axis of the receiving plate 71, the rotating shaft 41 drives the accumulated powdered raw materials to improve the fluidity of the powdered raw materials. At this time, the raw materials are filtered along the receiving plate 71 to the grinding plate 73 below, so that the impurities in the raw materials are separated from the powdered raw materials after filtration. The rotating shaft drives the grinding rotor 72 to rotate on the grinding plate 73, and the thrown powdered raw materials are selected for grinding to make the raw materials finer. Then, the raw materials after grinding fall into the receiving base 5, and the ground agglomerated raw materials are broken up by the rotating dispersion component 4.

[0050] The staff starts the motor 1, and the motor 1 drives the dispersion component 4, the rotating seat 75 and the grinding rotary block 72 to rotate. Then the staff pours the powder raw material into the interior of the screening barrel 2, and the powder raw material accumulates in the receiving tray 71. At this time, the rotating shaft 41 rotates at the axis of the receiving tray 71, so that the axis of the receiving tray 71 is in an active state, and the powder raw material accumulated on the receiving tray 71 keeps sliding due to the activity, so as to avoid the accumulation of raw materials in the receiving tray 71 when they are introduced, affecting the screening efficiency.

[0051] After being screened by the receiving plate 71, the raw materials fall onto the top of the inclined pad 74. At this time, the rotating shaft 41 drives the rotating seat 75 and the grinding block 72 to rotate on the surface of the grinding disk 73. The raw materials above the inclined pad 74 are thrown outward by the rotating centrifugal force, and slide between the grinding disk 73 and the grinding block 72 according to the shape of the grinding disk 73, and are rotated and ground by the grinding block 72 to form a finer powder raw material.

[0052] The raised pad 712 arranged at the center of the receiving plate 71 is sleeved on the surface of the shaft 41. When the powder raw material is poured into the filter plate 713, the powder raw material is screened along the discharge hole 711 to the inclined pad 74 below. The impurities in the raw material cannot be screened out from the discharge hole 711. The impurities slide along the inclined filter plate 713 to the side of the raised pad 712, so that the screened impurities gather at the connection between the filter plate 713 and the raised pad 712, so as to facilitate the collection of the screened impurities and prevent the impurities from blocking the discharge hole 711.

[0053] After preliminary screening, some powder raw materials fall to the top of the inclined pad 74, and the inclined pad 74 rotates on the outside of the shaft 41 along with the rotating seat 75 and the grinding block 72. At this time, the powder raw materials on the inclined pad 74 are thrown outward due to the centrifugal force, and slide downward along the gap between the arc disk 731 and the grinding block 72. At this time, the rotating grinding block 72 crushes and grinds the raw materials, making the powder raw materials finer and then sifted out from the extrusion hole 732 to improve the fineness of the raw materials.

[0054] The staff starts the motor 1 so that the output end of the motor 1 drives the shaft 41 to rotate. At this time, the ring 45 drives the receiving arc piece 42 to rotate under the grinding disc 73 and contact with the falling powder raw material to cushion the falling powder, so that the powder raw material slides downward along the receiving arc piece 42, thereby reducing the dust generated when the powder raw material falls.

[0055] The receiving arc piece 42 drives the bending rod 441 to rotate in the receiving base 5, and the raw materials stored and accumulated in the screening barrel 2 are moved by multiple sets of elastic paddles 444 to break up the agglomerated raw materials during grinding and rolling, while preventing the powder raw materials from being accumulated too high after being screened and discharged, causing blockage under the grinding disc 73.
