Description

Technical Field

[0001] The utility model belongs to the technical field of pigment storage, and in particular relates to a pigment storage tank which can prevent pigment from condensing. Background Art

[0002] Pigment is a colored fine-grained powdery substance that is generally insoluble in water and can be dispersed in various media such as oil, solvent and resin. It has covering power and tinting power and is relatively stable to light. It is often used in the preparation of paints, inks and colored plastics and rubbers. Therefore, it can also be called a colorant. Pigments are usually needed in the process of art creation.

[0003] After the pigment is produced, it needs to be stored in a storage tank. The existing storage tank needs to be frequently opened each time the material is taken out, which causes humid air to enter the storage tank, causing the pigment to become damp during storage. The damp pigment will adhere to the inner wall of the storage tank, making it inconvenient to clean and affecting production efficiency. Most existing pigments do not have a drying function during the production and processing process, so that the pigment will coagulate during long-term storage, affecting the quality of the pigment product. Utility Model Content

[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] Please also refer to Figures 1 to 4 The following is a detailed description of the paint storage tank that can prevent paint from coagulating according to an embodiment of the present invention with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the pigment storage tank that can avoid pigment coagulation includes a storage tank body 1, a bracket 2 is fixed to the bottom of the storage tank body 1, a servo motor 3 is fixed inside the bracket 2, and the servo motor 3 is connected to the output shaft 4 at the end facing the storage tank body 1, a cover plate 5 is fixed to the top of the storage tank body 1 with screws, a rotating shaft 6 is fixed to the end of the cover plate 5 facing the inside of the storage tank body 1, the rotating shaft 6 is plugged into the outside of the output shaft 4 away from the cover plate 5, a heating rod 7 is plugged into the inside of the rotating shaft 6, an annular groove 8 is provided on the side of the rotating shaft 6, the inside of the annular groove 8 is filled with activated carbon particles, and a number of through holes 9 are provided on the side of the annular groove 8, and a derivation pipe 10 is also fixed to the end of the cover plate 5 facing the inside of the storage tank body 1, and the derivation pipe 10 is connected to the connecting pipe 11 away from the end of the storage tank body 1.

[0023] A baffle 12 is hingedly connected to the end of the outlet pipe 10 facing the interior of the storage tank 1 . The baffles 12 are symmetrically arranged about the middle of the outlet pipe 10 . When the two baffles 12 are not rotated, they completely cover the bottom of the outlet pipe 10 .

[0024] A connecting seat 13 is fixed to the inner wall of the outlet pipe 10, and a groove 14 is provided inside the connecting seat 13. A cross bar 15 is rotatably connected inside the groove 14. The cross bar 15 is fixedly connected to one side of the baffle 12. A torsion spring 16 is sleeved on the outside of the cross bar 15 on both sides of the baffle 12. One end of the torsion spring 16 is fixed to the side of the baffle 12, and the other end is fixed to the inner wall of the groove 14, so that the baffle 12 can rotate synchronously with the cross bar 15. When the external extraction pipe enters the outlet pipe 10, the extraction pipe contacts the surface of the baffle 12, driving the baffle 12 to rotate, and then the baffle 12 rotates toward the inside of the storage tank body 1. At this time, the torsion spring 16 rotates and compresses. After the extraction pipe is extracted, the torsion spring 16 resets, driving the baffle 12 to rotate again, resets, and then quickly closes the outlet pipe 10.

[0025] A slot 17 is provided at the end of the rotating shaft 6 facing the output shaft 4, and an annular rib 18 is fixed to the side of the output shaft 4. After the output shaft 4 is inserted into the slot 17, the annular rib 18 abuts against the inner wall of the slot 17. The annular rib 18 abuts against the inside of the slot 17, increasing the friction between the output shaft 4 and the rotating shaft 6, ensuring that the two rotate synchronously.

[0026] At the same time, a telescopic rubber plate 19 is provided on the outside of the rotating shaft 6. One end of the telescopic rubber plate 19 is fixed to the side of the rotating shaft 6, and the other end is connected to a connecting rod 20. The connecting rod 20 extends out of the cover plate 5 away from the end of the telescopic rubber plate 19. The extended cover plate 5 is fixed with a cylinder 21. The height of the telescopic rubber plate 19 covering the rotating shaft 6 can be changed according to the amount of paint stored in the storage tank 1, thereby blocking the through holes 9 on the side of the rotating shaft 6 in turn.

[0027] An air outlet pipe 22 is further provided near the top of the storage tank body 1 , and an air relief valve 23 is fixed to the outside of the air outlet pipe 22 to avoid excessive pressurization due to heat inside the storage tank, and exhaust can be discharged through the air relief valve 23 .

[0028] The working principle of the utility model is as follows: after placing the pigment inside the storage tank body 1, the cover plate 5 is installed on the top of the storage tank body 1 by screws. After the cover plate 5 is installed, the rotating shaft 6 on it is automatically plugged into the outside of the output shaft 4. The output shaft 4 is fixed by the annular rib 18 against the outside of the rotating shaft 6. Then, after the servo motor 3 is driven, the output shaft 4 and the rotating shaft 6 can rotate synchronously. Therefore, in order to ensure the dryness of the inside of the storage tank body 1, the servo motor 3 and the heating rod 7 can be turned on at a fixed time. As the rotating shaft 6 rotates, the heat emitted by the heating rod 7 is evenly distributed to the pigment. At the same time, when the pigment is stored, as the pigment enters, the cylinder 21 is opened, and the cylinder 21 is driven to drive the telescopic rubber plate 19 to move upward to prevent the pigment from entering the annular groove 8 along the through hole 9 on the side of the rotating shaft 6, and the idle area above the pigment liquid level can absorb water vapor through the activated carbon particles inside the annular groove 8 to prevent the air on the pigment from being humid, thereby further preventing the pigment from condensing; when taking out the pigment, the extraction tube is inserted into the outlet tube 10, and the baffle 12 is opened to enter the storage tank body 1 to extract the pigment.

[0029] The heating rod provided therein is a conventional rod-shaped resistance structure, and the top of the heating rod is connected to an external power supply through a wire.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
