Technical Field

[0001] The utility model relates to the technical field of ceramic production, in particular to a replaceable ceramic raw material proportioning device. Background Art

[0002] Ceramic raw materials mainly include natural raw materials and synthetic raw materials. Natural raw materials such as feldspar, clay and quartz are typical silicate materials, which are sintered to form ordinary ceramic materials. These materials are rich in sources, low in cost, mature in technology, and can be divided into daily-use ceramics, building ceramics, chemical ceramics, etc. according to performance characteristics and uses. Clay is another main raw material for making ceramics. It is made through processes such as crushing and screening of natural ore, and there are many types, such as porcelain clay and stoneware clay. Different types of clay will affect the texture and quality of ceramics.

[0003] Special ceramic materials are made of highly pure synthetic raw materials and formed and sintered through precisely controlled processes, and have special properties, such as oxide ceramics, nitride ceramics, cermets, etc. Nano-ceramics is an advanced field in the science of ceramic material preparation. It uses raw materials and the grains after forming to reach the nano-scale, which brings more extensive uses for ceramic materials.

[0004] In the process of ceramic production, different raw materials often need to be mixed and processed in different proportions. The existing method of adding raw materials often determines the amount of raw materials by single weighing. Finally, after each raw material meets the required proportion, it is input into the interior of the processing device. For a proportioning device that can directly input into the interior of the processing device after weighing, it is generally configured with multiple independent weighing parts. When in use, the feeding port at the top of the processing device needs to correspond to multiple independent weighing devices. When a single weighing device is contaminated, it is difficult to clean, which easily affects the continuation of the raw material proportioning work. Content of the Utility Model

[0025] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0026] Embodiment 1:

[0027] This embodiment introduces the specific structure of a replaceable ceramic raw material proportioning device, specifically referring to Figures 1-4 as shown, including a plurality of feeding hoppers 1, a switching frame 3 arranged at the bottom of the plurality of feeding hoppers 1, and a weighing mechanism 4 arranged on one side of the bottom of the switching frame 3. The inner wall of the switching frame 3 is processed with an internal gear ring 5, the inner side of the internal gear ring 5 is meshed and connected with a gear 7, the bottom of the gear 7 is connected in a transmission manner with a motor 6, the weighing mechanism 4 includes a weighing valve plate 403 and a weighing support 402, and one end of the weighing support 402 is connected in an assembled manner with a hydraulic cylinder 401;

[0028] One end of the hydraulic cylinder 401 extends into the interior of the weighing support 402 and is fixedly assembled with one side of the weighing valve plate 403. When the hydraulic cylinder 401 works, it can push the weighing valve plate 403 to slide inside the weighing support 402. The bottom surface of the feeding hopper 1 is attached to the top surface of the weighing support 402. By positioning the bottom of the feeding hopper 1 directly above the weighing valve plate 403, when the target ceramic raw material is conveyed into the feeding hopper 1 on top of the weighing valve plate 403, the raw material can flow through the feeding hopper 1 onto the top of the weighing valve plate 403, thus being weighed by the weighing valve plate 403. After weighing, the raw material is released to the bottom by controlling the sliding of the weighing valve plate 403 inside the weighing support 402 through the hydraulic cylinder 401;

[0029] Secondly, to enable the switching frame 3 to rotate outside the support column 2 and drive multiple feeding hoppers 1 to switch to the top of the weighing valve plate 403, providing different weighing channels for different raw materials. As shown in Figure 1 、 Figure 2 and Figure 4 a support column 2 is provided at the center of the bottom of the switching frame 3. The top of the support column 2 has an interference fit with a bearing 11. By supporting the bearing 11 at the bottom of the switching frame 3, the motor 6 and the gear 7 are both connected in a retractable manner inside the switching frame 3. When the motor 6 controls the rotation of the gear 7, the gear 7 can be used in cooperation with the internal gear ring 5 to control the rotation of the switching frame 3 outside the support column 2;

[0030] At the same time, the bottom surfaces of multiple feeding hoppers 1 are at the same height. When the rotating switching frame 3 drives multiple feeding hoppers 1 to switch to the top of the weighing valve plate 403, interference between the bottom of the feeding hopper 1 and the weighing support 402 can be avoided, preventing the target feeding hopper 1 from rotating to the top of the weighing valve plate 403;

[0031] Furthermore, to prevent the feeding hopper 1 from affecting the weighing of the ceramic raw material by the weighing valve plate 403 at the bottom. As shown in Figure 4 multiple receiving column grooves 9 are machined inside the periphery of the switching frame 3. Limiting rings 8 are machined on the middle outer walls of multiple feeding hoppers 1. A spring 10 is connected to the bottom of the feeding hopper 1 in a socketed manner. By passing the bottoms of multiple feeding hoppers 1 through multiple receiving column grooves 9 and out of the interior of the switching frame 3 respectively, and with the spring 10 supported between the bottom inner wall of the receiving column groove 9 and the bottom of the limiting ring 8, when the ceramic raw material in the feeding hopper 1 presses downward, the spring 10 can be compressed by the sliding of the limiting ring 8 inside the receiving column groove 9, enabling the weight of the ceramic raw material to be weighed by the weighing valve plate 403 through the feeding hopper 1.

[0032] Specifically, when using this replaceable ceramic raw material proportioning device for weighing and proportioning ceramic raw materials:

[0033] First, the target ceramic raw material is conveyed into the hopper 1 located at the top of the weighing valve plate 403. When the ceramic raw material is conveyed from the hopper 1 to the top of the weighing valve plate 403, the ceramic raw material in the hopper 1 presses downward, and the spring 10 is compressed by means of the sliding of the limit ring 8 inside the receiving column groove 9, so that the weight of the ceramic raw material can be weighed by the weighing valve plate 403 through the hopper 1.

[0034] Next, the hydraulic cylinder 401 is started to drive the weighing valve plate 403 to slide inside the weighing support 402, opening the channel inside one end of the weighing support 402 to allow the ceramic raw material to fall downward.

[0035] After the weighing of a single ceramic raw material is completed, the motor 6 controls the rotation of the gear 7. By using the cooperation of the gear 7 and the internal gear ring 5, the switching frame 3 is controlled to rotate outside the support column 2, so that another hopper 1 moves to the top of the weighing valve plate 403 to continue the weighing work of other ceramic raw materials. During this process, different ceramic materials can be weighed by using multiple hoppers 1. And when a single hopper 1 is contaminated, it can be taken out from the switching frame 3, and the remaining hoppers 1 can perform the corresponding functions.

[0036] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
