Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] like Figure 1-5 As shown, a stepped feeding and mixing device for paint raw materials includes a frame 1, on which a mixing tank 2 is installed. A vertical partition plate 3 is provided inside the mixing tank, dividing the mixing tank into a stirring tank 4 and a washing tank 5. The stirring tank includes a front mixing area 6 and a rear stepped falling area 7. A step device 8 is provided on the stepped falling area. In use, the two components of the paint raw materials are injected from the funnel above the top step device, and are first initially mixed at the top step device, and then fall step by step to the mixing area for stirring and mixing, and finally output.

[0025] In this embodiment, to enable the paint material to fall sequentially on the step device, the step device includes an inclined step panel 9. Several step grooves 10 are arranged on the surface of the step panel from top to bottom. The depth of each step groove decreases sequentially from top to bottom, i.e., the upper step groove is deeper than the lower one. The step grooves are triangular in shape, i.e., the upper part is open, and the lower part is an angled groove formed by two groove walls. The step grooves are sequentially connected to form the step panel. More specifically, in this embodiment, the step groove has one vertical inner wall and the other inclined inner wall. The angle between the inclined inner wall of the step groove and the horizontal plane decreases progressively from top to bottom, i.e., the angle between the inclined inner wall of the upper step groove and the horizontal plane is greater than the angle between the inclined inner wall of the lower step groove and the horizontal plane. This makes it easier for the paint material to flow from the step panel to the next step during its descent. Simultaneously, the inclined groove wall end of the upper step groove connects to the vertical groove wall end of the lower step groove, so that all the step grooves together form the step panel.

[0026] In this embodiment, in order to fix the stepped panel, the upper end of the stepped panel extends upward to form an upper extension plate 11, and the lower end of the stepped panel is bent horizontally to form a bent plate 12. The upper extension plate is fixed to the upper rear side of the mixing tank, and the bent plate is fixed to the bottom of the mixing tank.

[0027] In this embodiment, to prevent paint raw materials from falling between the lower surface of the stepped panel and the bottom of the mixing tank, the left and right edges of the stepped panel are connected to the left and right inner walls of the mixing tank, so that the perimeter of the stepped panel is closed with the sides and bottom of the mixing tank. At the same time, a support frame 13 for supporting the stepped panel is provided under the stepped panel in the mixing tank.

[0028] In this embodiment, to facilitate cleaning of each stepped groove, a clearance opening 14 is provided on the vertical partition plate corresponding to the stepped groove. The clearance opening connects the stepped groove and the cleaning pool. During cleaning, wastewater can be directly output from the clearance opening on the side of the stepped groove to the cleaning pool without having to spend time scooping water. The lower edge of the clearance opening is the curved surface of the corresponding stepped groove, which facilitates the output of wastewater. At the same time, when not cleaning, a sealing block 15 is inserted into the clearance opening to seal it. The clearance opening is closed by the sealing block to prevent paint raw materials from being exposed from the clearance opening during mixing.

[0029] In this embodiment, to specifically realize the connection between the sealing block and the clearance opening, an insert plate 16 is provided on the outer wall of the sealing block that abuts against the clearance opening. The insert plate is parallel to the vertical partition. A slot 17 is provided on the wall surface of the clearance opening corresponding to the insert plate. The insertion plate and the slot cooperate to achieve fixation. The end face of the sealing block extends into the clearance groove, increasing the contact area between the sealing block and the clearance groove, which facilitates increasing the number of sealing rings and better sealing.

[0030] In this embodiment, in order to better output the paint raw material mixture in the mixing area in front of the mixing tank, the bottom surface of the mixing area in front of the mixing tank is an inclined surface 18 with the front end down and the rear end up, and an output port is provided at the bottom of the front wall of the mixing tank.

[0031] In this embodiment, in order to facilitate the outflow of cleaning wastewater from the front of the cleaning tank, an inclined guide plate 19 is provided on the rear part of the cleaning tank. The upper end of the inclined guide plate is fixed to the inner wall of the rear side of the inclined tank, and the lower end of the inclined guide plate is fixed to the bottom of the cleaning tank. The plate surface of the inclined guide plate is lower than the corresponding clearance opening, that is, the inclined surface of the inclined guide plate should be located below the inclined surface formed by the bottom of each clearance opening to avoid interference. A sewage outlet is provided at the bottom of the front side wall of the cleaning tank.

[0032] In this embodiment, two high-level funnels 20 are arranged side by side above the highest step groove. Guide pipes 21 are connected to the output ports of the two high-level funnels. The two guide pipes are at an angle to each other, so that the two high-level funnels meet before falling to the bottom of the highest step groove, so that the two groups come into contact at the first time, which provides the possibility for subsequent uniform mixing. For reasonable design, a low-level funnel 22 is arranged above the mixing area. The height of the front side wall of the mixing pool is less than the height of the rear side wall.

[0033] In this embodiment, a stirring mechanism support 23 is mounted above the mixing zone. A rotating shaft 24 is rotatably connected to the lower part of the stirring mechanism support. The lower end of the rotating shaft extends into the paint raw material within the mixing zone. Two sets of stirring blades 25 are axially spaced at the lower end of the rotating shaft. The diameter of the upper stirring blade is 0.8 times that of the lower stirring blade. The smaller diameter of the upper stirring blade allows for agitation even at the center of the vortex, while the larger diameter of the lower stirring blade agitates the entire mixing tank. A motor 26 for driving the rotating shaft is mounted on the stirring mechanism support. The rotating shaft is located at the center of the mixing zone, and the low-level funnel is located at the edge of the mixing zone, without interfering with the stirring mechanism support.

[0034] In this embodiment, during use, the two components of the paint are injected from the two high-level funnels of the highest step groove. Due to the existence of each step groove, the two components of the paint are accumulated in the step groove of each step. As the paint is continuously injected, the mixture in each step groove is stirred and gradually mixed. When the paint enters the mixing area, the stirring shaft stirs it again to make the paint very uniform.
