Description

Technical Field

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

[0002] Mullite ceramics refer to ceramics whose main crystal phase is mullite. Mullite ceramics have the characteristics of high melting point, creep resistance, low expansion coefficient, excellent thermal shock resistance and corrosion resistance. In the processing and production of mullite ceramics, the ceramic raw materials need to be wet-ground to form raw material slurry, and the ceramic raw materials produced by grinding still contain some impurity particles of different sizes. In order to ensure the quality of later ceramic processing and production, the impurity particles in the ceramic raw materials need to be filtered and screened. Especially in the processing and production of some high-quality ceramics, manual screening and impurity removal are still required. The existing manual screening and impurity removal has the following shortcomings:

[0003] (1) In order to ensure the quality of the screening of ceramic raw materials, workers need to prepare a large number of sieve plates with different apertures. Workers need to repeatedly pour the ceramic raw materials onto different sieve plates to perform the screening operation, which is time-consuming and laborious.

[0004] (2) In the existing process of screening and removing impurities from ceramic raw materials, splashing occurs when the ceramic raw materials are poured onto the sieve plate, causing pollution;

[0005] (3) During the multiple screening and impurity removal processes, the sieved granular impurities remain on the surface of the sieve plate and block the sieve holes, affecting the subsequent screening and impurity removal efficiency of the ceramic raw materials;

[0006] Therefore, there is an urgent need for a raw material processing device for preparing infrared-transmitting mullite ceramics. Utility Model Content

[0030] Embodiment 1, a raw material processing device for preparing infrared-transmitting mullite ceramics, comprising a bottom plate 7, two support plates 1 perpendicular to the bottom plate 7 and parallel to each other are arranged on the upper surface of the bottom plate 7, and a plurality of mounting grooves 11 are arranged in an orderly manner from top to bottom on the opposite surfaces of the two support plates 1, and one end of the mounting groove 11 is an open structure, and a filtering mechanism 2 for filtering and screening impurities in the ceramic raw material is installed in the corresponding mounting grooves 11 on the two support plates 1, and the plurality of filtering mechanisms 2 are arranged in sequence from top to bottom, and the diameter of the sieve holes decreases in sequence from top to bottom, and the filtering mechanism 2 comprises a filtering groove 9 of an inverted trapezoidal structure, and support rods 8 matching the mounting grooves 11 are arranged on both sides of the filtering groove 9, the inner bottom surface of the filtering groove 9 is open, and a filter screen 10 matching the opening is arranged at the open position, and a collecting groove 4 for collecting the filtered ceramic raw material is detachably installed at the lower part of the plurality of filtering mechanisms 2;

[0031] When filtering impurities in ceramic raw materials, the staff pushes the device to the discharge port of the grinding equipment or the mixing equipment, and the raw materials enter from the top filter mechanism 2, and then are filtered out from the lower filter mechanism 2 step by step, thereby filtering the impurities in the ceramic raw materials step by step. The filtered ceramic raw materials fall into the collecting tank 4 for collection. When cleaning the filter mechanism 2, the filter mechanism 2 can be directly pulled out from the open end of the installation groove 11.

[0032] Embodiment 2: In the process of filtering impurities in the ceramic raw material, the filtered impurities will clog the filter screen 10, affecting the filtering effect of the ceramic raw material. For this reason, a vibration mechanism 3 for driving the filtering mechanism 2 to vibrate in the horizontal direction is further provided between the two support plates 1. The vibration mechanism 3 includes a vibrator 12, a top plate A13, a top plate B15 and a spring 14. A top plate A13 matching the inner wall clearance of the mounting groove 11 is provided in the mounting groove 11 on the support plate 1. A vibrator 12 for driving the top plate A13 to vibrate is provided between the top plate A13 and the inner bottom surface of the mounting groove 11.

[0033] During the installation of the filter mechanism 2, the support rods 8 on both sides of the filter mechanism 2 respectively conflict with the top plate A13 and the top plate B15 in the installation groove 11.

The upper surface of the bottom support plate 17 is an inner concave arc surface 18 with a low middle and a high inner circumference. When the collecting tank 4 is moved away, the ceramic raw materials dripping from the filtering mechanism 2 fall onto the upper part of the bottom support plate 17, and the staff can clean it by disassembling the bottom support plate 17.
