The utility model discloses a sewage treatment suspended solid separation equipment, include: separation storehouse, the separation storehouse top opening is used for sewage to enter, the lower extreme of separation storehouse is provided with the export of sewage discharge, separation structure is set up in the inside of separation storehouse, and separation structure includes the filter cover of conical design, and the filter cover is fixed in the inside of separation storehouse, and the outer wall of separation storehouse is provided with the collection storehouse, and the inner wall of separation storehouse is provided with the separation mouth that is communicated with the upper portion of the inside chamber of collection storehouse, and when the filter cover is fixed in separation storehouse, and the separation mouth is located at the lower extreme periphery of filter cover and is flush with the lower extreme of filter cover, and when the sewage enters separation storehouse, and the suspended solid is filtered by filter cover and is guided to the separation mouth and enters collection storehouse and is collected. The conical filter cover design utilizes sewage flow inertia, avoids the massive accumulation of suspended solid on the surface of filter cover, effectively reduces the frequency of filter cover blockage, reduces the number of cleaning filter cover, thereby reduces the operation cost and maintenance workload.

The application discloses a circulating fan for dry quenching system and relates to the field of circulating fans, which comprises a fan shell, an air inlet, an air outlet, an air inlet flange, a cleaning cylinder arranged at the air inlet of the fan shell, a filter cylinder arranged in the cleaning cylinder, wherein the filter cylinder is in the shape of a truncated cone, the smaller end of the filter cylinder is arranged away from the fan shell, and a wind guide cylinder corresponding to the filter cylinder is arranged at the end of the cleaning cylinder away from the fan shell; and a dust collecting unit is arranged at the end of the filter cylinder close to the fan shell, which is used for collecting and treating the impurities filtered out. The cleaning cylinder with the filter cylinder in the shape of a truncated cone is arranged at the air inlet of the fan, the coke powder and dust impurities in the circulating gas are completely filtered out before entering the fan shell through the front filter structure, the problems of the erosion and abrasion of the fan impeller and the internal flow channel and the flow channel blockage caused by the dust are avoided from the root, the operation failure rate of the fan is significantly reduced, and the service life of the whole machine is prolonged.

The present application relates to sucrose crystallization technical field, and disclose a forced circulation crystallizer for trichloro sucrose mother liquor, including rack, the rack is installed with crystallization kettle and mother liquor tank, the filter assembly is provided in the mother liquor tank, the filter assembly includes mounting frame, the mounting frame is fixed in the inside of mother liquor tank, and the side surface of mounting frame is combined with the inner face of mother liquor tank, two rotating shafts are rotatably installed on the mounting frame, and the two rotating shafts are located at the two ends of mounting frame respectively, the roller is fixedly sleeved on each rotating shaft, and the two rollers are drivenly connected by filter membrane, the filter assembly further includes motor, and the motor is installed on the side surface of mother liquor tank.The present application works, the filter membrane under the motion state makes the mother liquor flow through different areas uniformly by continuous movement, avoids local blockage, and the impurities are uniformly dispersed on the membrane surface, the effective filtering area is expanded and the service life of single point is prolonged, and the vibration or water flow scouring effect promotes the impurities to fall off.

This utility model relates to the field of ceramic membrane module technology, and in particular to an irregularly shaped ceramic membrane module, including an inlet pipe. The bottom end of the inlet pipe vertically penetrates the middle of the top of a first end cap. The bottom end of the first end cap is screwed to the top opening of a main cylinder. A second end cap is screwed to the bottom opening of the main cylinder. A clear water pipe vertically penetrates the middle of the bottom of the second end cap. A product water center pipe is provided at the top opening of the clear water pipe. The upper and lower ends of the product water center pipe vertically penetrate the middle of upper and lower fixing plates, respectively. Several irregularly shaped ceramic membranes vertically penetrate the opposite sides of the upper and lower fixing plates. A concentrate pipe vertically penetrates one side of the bottom of the second end cap. This device adopts a honeycomb structure design of hexagonal irregularly shaped ceramic membranes, realizing a high-density orderly arrangement of irregularly shaped ceramic membranes, increasing the effective filtration area per unit volume, and optimizing water flow distribution through geometric symmetry, reducing dead zones and improving filtration efficiency.
