Description

Technical Field

[0001] The utility model relates to the technical field of micro-crystal-type fluidized beds, in particular to a micro-crystal-type fluidized bed solid-liquid separator. Background Art

[0002] The microcrystalline granulation fluidized bed softening method is a new softening method. Currently, it is rarely used in China. This method mainly adds a certain proportion of crystal seeds to the water according to the hardness and alkalinity components in the water, and then adds alkaline reagents (such as sodium hydroxide, sodium carbonate) to mix evenly with the water and react with the alkali in the water. The crystallization and granulation process is completed by equipment and hydraulic action, thereby achieving the effect of softening the water. When using a microcrystalline fluidized bed, a solid-liquid separator is required to separate the liquid and the impurities inside it.

[0003] In the process of solid-liquid separation of liquids, a combination of physical filtration and chemical reaction deposition is often required. The impurities in the liquid that cannot be directly physically filtered are first subjected to chemical reactions to form large particles of impurities that can be physically filtered. Then they are concentrated and passed through multiple filter screens for fine filtration and separation. The existing filter screens are often directly installed in the water flow path when filtering sewage, and the direct current sewage is directly screened through the filter screen. However, in this method, only the bottom filter screen of the filter screen is subjected to force, and the amount of filtrate passing through the side is small and lacks the impact force to pass through the filter screen, resulting in insufficient utilization of the overall filter surface of the filter screen and concentration on the bottom filter screen, which is prone to clogging problems. Utility Model Content

[0004] The purpose of the utility model is to provide a micro-crystalline fluidized bed solid-liquid separator, which makes full use of the filter screen area of ​​the filter cover to assist solid-liquid separation, avoids the problem of direct-flow filtration in which only the bottom filter screen of the filter cover is subjected to force for solid-liquid separation, while the amount of filtrate on the side is small and lacks impact force, improves the utilization rate of each filter surface and avoids the problem of accumulation and clogging of the bottom filter screen.

[0005] In order to achieve the above-mentioned purpose, a micro-crystalline fluidized bed solid-liquid separator is provided, including an isolation chamber, a centrifugal cylinder is mounted at the inner center of the isolation chamber, a swivel is rotatably fitted at the top center of the centrifugal cylinder, a liquid inlet pipe is fixedly engaged with the upper and lower sides of the inner side of the swivel, the liquid inlet pipe extends upward from the outside of the isolation chamber and a limiting ring seat is fixed on it, the bottom outer side of the limiting ring seat is fixedly connected with a top cover, the top cover is fixedly engaged with the isolation chamber downward, a first filter cover is mounted on the outer side of the centrifugal cylinder, a second filter cover is mounted downward on the outer side of the first filter cover, a third filter cover is mounted downward on the outer side of the second filter cover, a screen is fitted around the tops of the third filter cover and the second filter cover, a clamp is fixed at the bottom center of the centrifugal cylinder, and the clamp extends downward from the first filter cover The bottom side of the filter cover is equipped with a waterproof motor for rotation, and a shell is mounted on the outside of the waterproof motor.

[0006] According to the micro-crystal fluidized bed solid-liquid separator, a guide groove is fixedly mounted on the inner side of the bottom of the trapezoidal liquid discharge hopper. The guide groove is arranged in a front-to-back direction and filled with a slow-flow sponge block to help guide the liquid downward and reduce its flow rate to avoid splashing.

[0007] According to the micro-crystalline fluidized bed solid-liquid separator, a double-layer filter plate is mounted directly above the trapezoidal liquid outlet hopper. The outer side of the double-layer filter plate is embedded in the inner wall of the isolation chamber and slides back and forth therewith. A sealing clip is fixedly connected to the center of the front side of the double-layer filter plate. The front side of the sealing clip extends outside the isolation chamber and is fixedly engaged therewith. High-density filtration is performed to ensure complete solid-liquid separation.

[0008] According to the micro-crystal type fluidized bed solid-liquid separator, a pull handle is fixedly connected to the center of the front side of the sealing clamp plate, which facilitates the removal of the double-layer filter plate for cleaning.

The outer side of the sealing ring is embedded in the inner wall of the first filter housing and is rotatably connected thereto, thereby preventing water from seeping into the housing and affecting the output power of the waterproof motor.

This facilitates workers to hold the liquid inlet pipe upward to open the top cover and inspect and clean the filtering equipment inside the isolation chamber.

[0011] According to the micro-crystal fluidized bed solid-liquid separator, the inner wall of the isolation chamber is covered with a slip film made of nano waterproof material, which prevents the liquid thrown onto the inner wall of the isolation chamber from penetrating and guides it downward.
