In order to completely solve this problem, a centrifuge efficient liquid feeding structure is developed to improve the centrifuge liquid feeding effect and equipment efficiency.

[0005] Preferably, a filter screen is provided on the filter cartridge, by which the filter screen can be conveniently adjusted in the process of gypsum dehydration, while avoiding the loss of raw materials caused by the filter residue flowing out of the filtrate outlet with the filtrate due to the large filtration aperture directly using the filter cartridge.

By designing a washing nozzle, cleaning and washing after each dehydration and filtration can effectively solve the clogging problem.

[0007] Preferably, a plurality of shock absorbing devices are also provided on the base to prevent the centrifuge from vibrating excessively during operation, thereby causing faults such as alarm and shutdown.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0017] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] like Figure 1 As shown, a gypsum dehydration centrifuge structure comprises a barrel 1, and the barrel 1 is equipped with a barrel cover 2, characterized in that: a filter barrel 3 is arranged in the barrel 1, the filter barrel 3 is fixedly mounted on a bearing 5, the bearing 5 is fixedly mounted on a main shaft 6 by a key mounting method, the main shaft 6 is transmission-connected to a motor 8 by a transmission belt 7, the motor 8 is fixedly mounted on a base 9, an upper liquid supply pipe 10 and a lower liquid supply pipe 11 are connected to the barrel cover 2 by a flange, an upper liquid supply nozzle 12 is arranged on the upper liquid supply pipe 10, a lower liquid supply nozzle 13 is arranged on the lower liquid supply pipe 11, the upper liquid supply nozzle 12 and the lower liquid supply nozzle 13 are both designed to be fan-shaped structures, a scraper 18 is also connected to the barrel cover 2 by a flange, and a horizontal distance between the scraper 18 and the inner wall of the filter barrel 3 is 0.5cm-2cm, and a filtrate port 19 and a feed port 16 are also provided on the barrel 1 and the filter barrel 3.

[0019] The filter cylinder 3 is provided with a filter screen 4, by which the filter pore size can be conveniently adjusted during the gypsum dehydration process, while avoiding the loss of raw materials caused by the filter residue flowing out of the filtrate port 19 with the filtrate due to the large filtration pore size caused by directly using the filter cylinder 3.

[0020] The cylinder cover 2 is connected to a filter screen washing pipe 14 via a flange, and the filter screen washing pipe 14 is provided with a plurality of washing nozzles 15. This design mainly takes into account that some filter residues remain on the filter cylinder 3 or the filter screen 4 when the scraper 18 scrapes the material. The gypsum becomes dry and hard after a long period of retention, which can easily cause the filter cylinder 3 / filter screen 4 to become blocked, thereby affecting the next use. By designing the washing nozzle 15, cleaning and washing after each dehydration and filtration can effectively solve the blockage problem.

[0021] The base 9 is also provided with a plurality of shock absorbing devices 17 to prevent the centrifuge from vibrating excessively during operation, thereby causing alarm and shutdown and other faults.

[0022] During the operation, first, the liquid feeding device (not shown) feeds the centrifuge with liquid through the upper liquid feeding pipe 10 and the lower liquid feeding pipe 11, and the motor 8 is started. The motor 8 drives the main shaft 6 to rotate through the transmission belt 7, so that the filter cylinder 3 rotates. At this time, under the action of centrifugation, the water in the liquid flows into the filtrate port 19 through the filter holes in the filter cylinder 3 and the filter screen 4 and is discharged. The material residue remaining in the filter cylinder 3 and the filter screen 4 is scraped off and falls into the discharge port 16 when the filter cylinder 3 rotates. When designing, the distance between the scraper 18 and the filter cylinder 3 is preferably kept at about 1CM. After the liquid is dehydrated, the washing device (not shown) is started, and the washing device sprays water through the washing nozzle 15 on the filter screen washing pipe 14, and cleans the material residue remaining on the filter cylinder 3 and the filter screen 4.

[0023] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
