Description

Technical Field

[0001] This utility model belongs to the field of pigment drying technology, and in particular relates to a drying oven for pigment testing. Background Technology

[0002] The solid content of a color paste refers to the percentage of the mass of solid components in the total mass of the color paste. Solid content is the percentage of the mass remaining after the emulsion or coating has dried under specified conditions; it can also be referred to as the "non-volatile content."

[0003] The solid content of pigment paste is usually determined by the drying method. The specific method involves drying the pigment paste sample under specific conditions, measuring the mass difference before and after drying, and then calculating the solid content. However, the drying effect of existing drying ovens is poor. Therefore, we propose a drying oven that can dry pigment paste well and facilitate the testing of pigment paste solid content. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a drying oven for color paste testing, in which a rotating frame drives the color paste sample to rotate slowly, thereby ensuring the drying effect.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a drying oven for color paste detection, comprising an inner box, an outer box, a heating tube, a rotating frame, and a rotation drive mechanism for driving the rotating frame to rotate. The rotating frame is located inside the inner box, the inner box is located inside the outer box, and a heat insulation cavity is formed between the inner box and the outer box to prevent heat dissipation and save energy to a certain extent.

[0006] The rotating frame includes a rotating shaft and several shelves. The shelves have through holes running vertically. The shelves are fixed to the rotating shaft, which is fixed to the rotating drive mechanism. During the color paste drying process, the rotating frame rotates slowly, which facilitates the contact between the color paste raw material and the air in the inner chamber, and forces the air to flow during rotation, thus ensuring the drying effect.

[0007] The heating tube is a serpentine heating tube that bends back and forth. The heating tube is installed on the heat dissipation assembly, which is fixed to the inner wall of the inner box. The heat dissipation assembly includes several fins and several collars. The collars are fitted onto the heating tube and are arranged along the direction of the heating tube. The fins correspond one-to-one with the collars, and the collars are connected to the fins. The fins are fixed to the mounting plate, which is fixed to the inner wall of the inner box. The serpentine heating tube and the heat dissipation assembly facilitate uniform temperature distribution inside the inner box, and the heating tube heats the interior of the inner box.

[0008] Furthermore, the rotary drive mechanism includes a rotary drive motor and a reducer. The rotary drive motor is fixed to the outer casing and connected to the reducer. The reducer is connected to the rotating shaft.

[0009] Furthermore, the inner box and the outer box are connected by several fixing blocks.

[0010] Furthermore, the fins are U-shaped fins.

[0011] Furthermore, the collar and the fin are integrally formed parts.

[0012] Furthermore, the inner box is provided with a first door, and the outer box is provided with a second door.

[0013] Furthermore, the plate is provided with a downwardly recessed receiving groove corresponding to the pigment sample.

[0014] Furthermore, the receiving groove is equipped with an elastic positioning structure for positioning the pigment sample. The elastic positioning mechanism includes a positioning plate and a positioning spring. The layer plate is provided with an installation groove. The positioning plate is connected to one end of a guide rod, and the other end of the guide rod is connected to a limiting head. The limiting head is located inside the installation groove. The positioning spring is provided between the limiting head and the inner wall of the installation groove to make the positioning plate press the pigment sample.

[0015] Furthermore, the positioning plate is provided with a guide slope, and the inclination direction of the guide slope gradually tilts from top to bottom toward the side away from the guide rod.

[0016] The beneficial effects of this utility model are at least as follows:

[0017] The heating tube of this utility model is a serpentine heating tube that bends back and forth. The heating tube is installed on the heat dissipation assembly, which is fixed to the inner wall of the inner box. The serpentine heating tube and the heat dissipation assembly facilitate uniform temperature distribution inside the inner box. The heating tube heats the inside of the inner box. It is worth mentioning that the rotating frame includes a rotating shaft and several shelves. The shelves have through holes. The shelves are fixed to the rotating shaft, which is fixed to the rotating drive mechanism. During the color paste drying process, the rotating frame rotates slowly, which facilitates the contact between the color paste raw material and the air inside the inner box, and forces the air to flow during rotation, thus ensuring the drying effect.

[0018] The inner box of this utility model is located inside the outer box, and a heat insulation cavity is formed between the inner box and the outer box to prevent heat loss and save energy to a certain extent.

[0019] The layer of this invention has a downwardly recessed receiving groove corresponding to the color paste sample, which positions the color paste sample and prevents it from moving. Attached Figure Description
