[0031] The following is combined with Figures 1 to 5 The present invention is further described in detail, but is not intended to limit the present invention.

[0032] like Figure 1 As shown, in one embodiment of the present invention, the coating slurry device includes a storage container 1, a placement table 2, an assembly component 3 and a controller 4; a accommodating cavity 101 is provided in the storage container 1; the accommodating cavity 101 is used to store the slurry required for coating; a discharge pipe 105 connected to the accommodating cavity 101 is provided at the bottom of the storage container 1; and a guide slope 104 is provided inside the storage container 1 near the discharge pipe 105; the assembly component 3 is connected to the outer wall of the storage container 1 in a surrounding manner; and the assembly component 3 is detachably connected to the placement table 2; the controller 4 is connected to the discharge pipe 105 to control the conduction or closure of the discharge pipe 105.

[0033] The technical solution of the present invention uses the guide slope at the bottom of the storage container to quickly guide the stored slurry to the discharge pipe under the action of gravity, and then discharges and loads the slurry through the control valve, thereby increasing the loading speed and ensuring the smoothness of loading; and through the detachable assembly of the assembly parts and the placement table, the storage container can be quickly disassembled, cleaned and maintained, thereby achieving a simple overall structure, improving the convenience of disassembly, cleaning and maintenance, and meeting the requirements of fast and relatively low-cost production.

[0034] Controller 4 is a manual valve. Furthermore, the manual valve includes a valve body, with a flow channel extending from side to side. A valve hole is formed at the upper end of the valve body, within which is a V-shaped valve plate for opening and closing the flow channel, and the valve plate is movable up and down within the valve hole. The outer side surface of the upper end of the valve plate forms an end-face seal with the inner wall surface of the valve hole. A sealing groove is formed at the bottom of the flow channel, within which the lower end of the valve plate is inserted. The outer side surface of the lower end of the valve plate forms an end-face seal with the inner side surface of the sealing groove port. Furthermore, the manual valve is a manual valve with model numbers S20A05-1X450J3, HV-02, HV-03, or HV-04. Therefore, manual mechanical control of the manual valve eliminates the need for external energy (such as electricity or gas) and effectively meets the requirements of rapid material loading and low-cost proofing production.

[0035] Specifically, in some embodiments, Figure 1 and 2 As shown, the storage container 1 is also equipped with a feed pipe 102 that communicates with the storage chamber 101; one end of the feed pipe 102 is connected to an external pipe 103. The feed pipe 102 is positioned adjacent to the discharge pipe 105. This structure, with its highly offset feed pipe 102 and discharge pipe 105, effectively ensures orderly feeding and discharging of materials, improving efficiency. Furthermore, one end of the external pipe 103 is threaded for assembly with external equipment.

[0036] Specifically, in some embodiments, Figure 1 and 2 As shown, the storage container 1 comprises a stacked tank body 11 and a lid body 12, forming a receiving cavity 101 between the tank body 11 and the lid body 12. A diversion slope 104 is provided on the inner wall of the tank body 11; a discharge pipe 105 is provided on the inner bottom of the tank body 11; and an assembly component 3 is provided around the outer surface of the tank body 11. This structure, with its separate tank body 11 and lid body 12, enables real-time monitoring of the slurry inside, improving orderly management and safe use. A U-shaped handle 121 is provided on the top of the lid body 12.

[0037] Specifically, in some embodiments, Figure 1 As shown, the diverter slope 104 is disposed around the inner bottom of the tank body 11. The inner diameter D of the diverter slope 104 near the lid 12 is larger than the inner diameter D of the diverter slope 104 near the discharge pipe 105, and the following conditions are met: D ≥ 20 mm. The inner diameter D of the diverter slope 104 gradually decreases from the lid 12 toward the tank body 11. This structure, with a large inner diameter at the inlet and a small inner diameter at the outlet, and D ≥ 20 mm, can effectively increase the slurry conveying speed and ensure stable and smooth slurry discharge.

[0038] Specifically, in some embodiments, Figure 2 and 3 As shown, the tank body 11 includes a straight section 111 and an inclined section 112 connected in sequence; and the cover body 12 is connected to one end of the straight section 111; and one end of the inclined section 112 passes through the placement table 2 and is connected to the controller 4. The angle between the inclined section 112 and the vertical direction is α; and 40°≤α≤65°. Furthermore, the inclination angle α of the inclined section 112 is the same as the inclination angle of the guide slope 104 in the same direction. In other words, by making the inclination angle α of the external inclined section 112 the same as the inclination direction and angle of the internal guide slope 104, its overall volume can be effectively reduced, the occupied space can be reduced, and the production cost can be reduced, thereby improving the efficiency of use.

[0039] Specifically, in some embodiments, Figure 2 As shown, the assembly component 3 is a square or circular plate with a connection hole 31 defined therein. The outer wall of the storage container 1 is connected to the interior of the connection hole 31. Furthermore, the outer wall of the can body 11 in the storage container 1 is welded or bonded to the interior of the connection hole 31. In other words, by using the assembly component 3 as a support point for assembly with the placement platform 2, wear and tear of the can body 11 during assembly can be avoided, thereby improving the stability of the can body 11 and extending its service life.

[0040] Specifically, in some embodiments, Figure 3 and 4 As shown, the interior of the storage platform 2 is provided with a mounting channel 22; the inner wall of the mounting channel 22 is provided with a limiting arc surface 21; the bottom of the storage container 1 (tank 11) passes through and is engaged with the mounting channel 22; and the sidewall of the bottom of the storage container 1 abuts against the limiting arc surface 21. In other words, the limiting arc surface 21 supports the bottom of the storage container 1, thereby achieving an upward supporting stress on the storage container 1, thereby improving the support stability, ensuring safety and stability in use, and ensuring convenient installation and removal.

[0041] Specifically, in some embodiments, Figure 2 and 3 As shown, the placing table 2 is provided with a first assembly hole 201; the assembly component 3 is provided with a second assembly hole 32 corresponding to the first assembly hole 201. Figure 5 As shown, in some embodiments, the assembly component 3 is detachably connected to the first assembly hole 201 and the second assembly hole 32 via threaded rods, thereby achieving a detachable connection between the placement table 2 and the assembly component 3. In other embodiments, the assembly component 3 is detachably connected to the first assembly hole 201 and the second assembly hole 32 via polished rods, thereby achieving a detachable connection between the placement table 2 and the assembly component 3.

[0042] Specifically, in some embodiments, Figure 4 and 5 As shown, the placement platform 2 is further provided with a positioning rail 23; a positioning rod 5 is movably mounted within the positioning rail 23; a positioning slot 33 is provided on the side of the assembly component 3; and the positioning rod 5 can be snapped onto the inner wall of the positioning slot 33. The positioning rod 5 is L-shaped, T-shaped, or I-shaped. After the assembly component 3 is assembled to the placement platform 2, the positioning rod 5 is slid toward the positioning slot 33 to engage the inner wall of the positioning slot 33, thereby improving assembly stability.
