Description

Technical Field

[0001] The utility model relates to the technical field of ceramic preparation, in particular to a batching device for preparing infrared-transmitting mullite ceramics. Background Art

[0002] In 1983, FJ Klug et al. used the sol-gel method to synthesize powder to prepare mullite transparent ceramics, and studied its infrared transmittance properties, and obtained infrared-transmitting mullite ceramics.

[0003] A Chinese patent with an existing publication number of CN114644513A discloses a method for preparing a mullite infrared transparent ceramic. In the process of preparing the infrared transparent mullite ceramic, a mixed powder is prepared by using alumina and silicon dioxide in a molar ratio of 1.70 to 1.94:1, which requires a batching device. The existing batching device generally adds two powders into a stirrer in turn, and then stirs and mixes the powders. This method is used for the two powders added into the stirrer to be relatively concentrated, which is not conducive to mixing. Therefore, a long stirring time is usually required, and the mixing effect is not ideal.

[0004] For this purpose, we designed a batching device for preparing infrared-transmitting mullite ceramics. Utility Model Content

The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0027] Embodiment 1, in combination with the attached Figure 1-4 A batching device for preparing infrared-transmitting mullite ceramics includes a base 1, a batching box 2 with a stirring assembly 3 in the middle of the inner cavity is provided on the top surface of the base 1; further, a discharge pipe 21 with a valve is provided at the bottom of the batching box 2.

[0028] As needed, the stirring assembly 3 includes a stirring motor 31 arranged on the top surface of the batching box 2, and the output end of the stirring motor 31 is coaxially fixed with a stirring shaft 32, and the stirring shaft 32 is correspondingly rotatably connected to the middle part of the inner cavity of the batching box 2, and a stirring rod 33 is provided at the lower end of the stirring shaft 32.

[0029] As required, a roller 51 for rolling the outer wall of the batching box 2 is provided at the telescopic end of the telescopic device 5 .

[0030] This arrangement can drive the batching box 2 to swing back and forth through the telescopic device 5 while stirring, so that the raw materials in the batching box 2 are turned over, especially the raw materials close to the wall of the batching box 2 and the mixing dead corner are turned over, thereby improving the stirring effect and the batching effect.

[0031] The top surface of the batching box 2 is provided with a feeding assembly 4 for adding raw materials;

[0032] The feeding assembly 4 includes a large feeding hopper 41, a small feeding hopper 42, a thick lead screw 43, a thin lead screw 44, a first valve plate 45 and a second valve plate 46. A large feeding port and a small feeding port are arranged at intervals on the top surface of the batching box 2. The large feeding port and the small feeding port have the same width, and the central axes of the two in the length direction are collinear; a large feeding hopper 41 is arranged on the top of the large feeding port, and a small feeding hopper 42 is arranged on the top of the small feeding port; a thick lead screw 43 is rotatably connected to one side of the large feeding hopper 41 corresponding to the small feeding hopper 42, and a thin lead screw 44 is rotatably connected to one side of the small feeding hopper 42 corresponding to the large feeding hopper 41, and the thick lead screw 43 and the thin lead screw 44 are coaxially fixed; the thick lead screw 43 is screwed with a first valve plate 45 capable of adjusting the opening degree of the large feeding port, and the thin lead screw 44 is screwed with a second valve plate 46 capable of adjusting the opening degree of the small feeding port.

[0033] Furthermore, a blade 34 is provided at the upper end of the stirring shaft 32, so that the whole raw materials being discharged can be dispersed, so that the two raw materials are mixed in the process of falling, which reduces the subsequent stirring time and is more conducive to uniform mixing.

[0034] This arrangement allows the weighed alumina to be poured into the large feeding hopper 41, and the weighed silica to be poured into the small feeding hopper 42, and then by rotating the thick lead screw 43 or the thin lead screw 44, the thick lead screw 43 and the corresponding fixed thin lead screw 44 drive the first valve plate 45 to move and open the large feeding port, and at the same time the small feeding port is also opened, so that the two raw materials enter the batching box 2 at the same time, so that the two are initially mixed, reducing the subsequent mixing time, and can also cooperate with the stirring component 3 while adding the raw materials, the stirring component 3 stirs the raw materials, reducing the subsequent mixing time;

[0035] Since the ratio of the two raw materials is constant, the widths of the large feed port and the small feed port are the same, so the pitch ratio of the thick lead screw 43 and the thin lead screw 44 is a ratio of alumina to silicon dioxide.

[0036] Furthermore, in order to better preliminarily mix the raw materials, guide plates 47 are provided at positions below the large feeding hopper 41 and the small feeding hopper 42 on the top surface of the batching box 2, and the two guide plates 47 form an inverted figure eight structure. In this way, the two added raw materials are guided through the corresponding guide plates 47 to combine into a falling flow. When they fall to the bottom of the batching box 2, the two raw materials are mixed again, further reducing the stirring time.

[0037] As required, upward retaining edges 471 are provided on both sides of the guide plate 47 .

[0038] Embodiment 2, combined with the attached Figure 1-4 , a batching device for preparing infrared-transmitting mullite ceramics, based on the first embodiment, a base 1 is provided with an upward vertical plate 11 at one end, and the upper end of the batching box 2 is correspondingly hinged to the top of the vertical plate 11;

[0039] Furthermore, the vertical plate 11 is provided with a telescopic device 5 for driving the ingredient box 2 to flip.

[0040] As required, a roller 51 for rolling the outer wall of the batching box 2 is provided at the telescopic end of the telescopic device 5 .

[0041] This arrangement can drive the batching box 2 to swing back and forth through the telescopic device 5 during the mixing process, so that the materials in the batching box 2 are turned over as a whole, thereby reducing the mixing time and improving the efficiency of the small class.

[0042] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
