Description
Technical Field
[0001] The utility model relates to the technical field of ceramic substrate production equipment, in particular to a batching device for preparing nitride ceramic substrates. Background Art
[0002] Nitrides include aluminum nitride, silicon nitride, boron nitride, etc. The raw materials of nitride ceramic substrates include powders and liquids, including nitride powders, thermal conductive powders, sintering aids, organic solvents, dispersants, etc. The raw materials need to be added to the mixing barrel in proportion, stirred and ground, and then vacuumed to obtain ceramic slurry. In the prior art, when adding raw materials to the mixing barrel, the mixing barrel needs to be opened for batching, so it is easy to entrain a large amount of air and generate dust during batching, affecting the production environment and increasing the cost of subsequent vacuum degassing. Utility Model Content
[0003] The technical problem to be solved by the utility model is: in order to overcome the disadvantage that when adding raw materials into a mixing barrel in the prior art, the mixing barrel needs to be opened for batching, which easily entrains a large amount of air and generates dust during batching, affecting the production environment and increasing the cost of subsequent vacuum degassing, the utility model provides a batching device for preparing a nitride ceramic substrate.
[0004] The utility model solves the technical problem by adopting the following technical scheme: a batching device for preparing a nitride ceramic substrate, comprising a stirring barrel and a cover, wherein the cover is provided with a stirring paddle extending into the stirring barrel, the stirring paddle is transmission-connected with a servo motor, the cover is provided with a vacuum tube connected with a vacuum pumping device, the cover is provided with a solid feed port and a liquid feed port, the solid feed port and the liquid feed port are provided with valve plates which can be opened toward the inner side of the stirring barrel, a batching barrel is provided at the upper end of the solid feed port and the liquid feed port, a screw cover is provided at the upper end of the batching barrel, a piston is provided in the batching barrel, a cylinder is provided on the screw cover, the cylinder output end passes through the screw cover and is connected with the piston, and a feed hole is provided on the upper side wall of the batching barrel.
[0005] During batching, the feed hole on the side wall of the batching barrel is used to add raw materials. Powders are added from the batching barrel where the solid feed port is located, and liquids are added from the batching barrel where the liquid feed port is located. After each raw material is added in sequence, the cylinder drives the piston to move downward, blocking the feed port, and then opens the valve plate to pour the raw materials into the mixing barrel; the piston blocks the feed hole, and then opens the valve plate for loading, which reduces the air entering the mixing barrel, ensures the vacuum environment in the mixing barrel, and thus ensures the normal degassing step, reducing the cost of using the vacuum equipment. The stirring paddle is used to stir and mix the raw materials in the mixing barrel.
[0006] Furthermore, the mixing barrel is made of a transparent material, and a volume scale mark is provided on the side wall of the mixing barrel.
[0007] Furthermore, in order to control the opening and closing of the valve plate, the two valve plates are hinged to the inner top wall of the cover, and a torsion spring for driving the valve plate to close the feed port is provided at the hinge point of the valve plate. An intermediate rod is connected between the two valve plates, and a driving rod is provided on the cover for sliding in a vertical direction. A driving plate is provided at the lower end of the driving rod, and the driving plate is resting on the connecting rod.
[0008] By pressing down the driving rod, the driving plate located at the lower end of the driving rod presses down the connecting rod. The connecting rod moves downward to drive the two valve plates to rotate along the hinge point to open the solid feed port and the liquid feed port, so that the raw materials in the batching barrel fall into the mixing barrel.
[0009] Furthermore, a sealing ring is provided between the driving rod and the cover, and a sealing ring cooperating with the solid feed inlet and the liquid feed inlet is provided on the upper end of the valve plate.
[0010] Furthermore, a pedal is provided on one side of the mixing barrel, a return spring is provided in the pedal, an L-shaped transmission rod is provided at the top end of the driving rod, and the other end of the L-shaped transmission rod is connected to the pedal.
[0011] The driving rod is arranged on the cover at a higher position, and the driving rod needs to overcome the elastic force of the torsion spring to press down the valve plate to open it, so it is very inconvenient for the staff to manually press down the driving rod. Therefore, it is more convenient and labor-saving to use an L-shaped transmission rod as an intermediate piece and open and close the valve plate by foot.
[0012] Furthermore, in order to control the slurry within a suitable temperature range, and thus control the viscosity of the slurry and the uniformity of the mixing, a water bath jacket for controlling the temperature of the slurry is provided on the outside of the mixing barrel. By introducing constant temperature water into the water bath jacket, the slurry in the mixing barrel is controlled within a suitable temperature range.
[0013] The beneficial effects of the utility model are as follows: the utility model provides a batching device for preparing a nitride ceramic substrate, which adopts two batching barrels arranged on a stirring barrel as a transfer, opens and closes a feeding hole by a piston, reduces dust, reduces the air entering the stirring barrel, and reduces the processing cost of degassing.
