摘要： A system and method for automatically cleaning air filters of a medical imaging system is provided. The method includes monitoring an air filter operating condition, determining that the air filter operating condition is not within a pre-determined threshold, and providing a control signal to at least one air filter. The at least one air filter comprises a motor, drive shaft, rotatable passive shaft, continuous belt air filter, and a stationary filter brush. The drive shaft is rotatably coupled to the motor. The continuous belt air filter is coupled to the drive shaft and the passive shaft. The stationary filter brush is mounted against the continuous belt air filter. The method includes rotating, by the motor in response to the control signal, the drive shaft to translate the continuous belt air filter around and between the drive shaft and the rotatable passive shaft, and across the stationary filter brush.

摘要： A microplastic filter includes a housing including an inlet configured to receive water. The microplastic filter also includes a fine filter disposed to rotate within the housing and configured to filter residues from the water. The microplastic filter further includes an inside wiper disposed within the fine filter. The inside wiper includes a center post disposed along a rotational axis of the fine filter and a helical curved wall spirally extending between the center post and the fine filter, where the helical curved wall is configured to guide a portion of the water to backflow through the fine filter and force away at least some filtered residues from pores of the fine filter to prevent fouling or clogging of the fine filter. In addition, the microplastic filter includes an outside wiper spirally disposed around the fine filter and configured to dislodge other filtered residues from the fine filter as the fine filter rotates.

摘要： A solids separator for use in a composting system for separating solid waste from liquid waste in a stream of waste includes a housing defining a waste inlet for receiving the stream of waste, a liquids outlet for passing the liquid waste, and a solids outlet for passing the solid waste. A separator belt is positioned within the housing and extending between the liquids outlet and the solids outlet, the separator belt defining a plurality of apertures through which the liquid waste passes through the separator belt and into the liquids outlet. A drive cylinder is rotatably mounted within the housing for selectively rotating the separator belt such that a top surface of the belt is moved toward the solids outlet along with the solid waste that is extracted from the stream of waste.

摘要： An incised surface is formed in one surface of a suction plate on the basis of a slit and a pattern roller is placed in a room, which is provided at a thickness part of the slit in which the incised surface is formed, to rotate in place so that the pattern roller partially protrudes outward from the incised surface and forms patterns on a surface of fleeces which are backwashed while passing through the slit so as to increase a filtration area of the fleeces. The backwash may be performed and the filtration area of the fleeces may be increased using the room. The spline-shaped patterns including splines cut to a certain length, patterns including several annular protrusions formed on an outer circumference of the pattern roller, spline-shaped patterns formed on the outer circumference, lattice-shaped patterns, and the like may be formed on a surface of the pattern roller.

摘要： A backwashing suction device for a fabric filtration apparatus, and more particularly, a backwashing suction device for a fabric filtration apparatus in which an edge surface of a suction slit through which pile threads exit is inclined to form a slope so that the pile threads introduced into the suction slit when a fiber disk filter is rotated for backwashing come into contact with the slope and thus the amount of angular rotation of the pile threads is increased to increase the backwashing effect. Also, since a plurality of friction protrusions are formed to protrude from the slope, the effect of removing foreign substances can be further enhanced through the effect of rubbing and washing the pile threads on a washboard while the pile threads ascend over each of the friction protrusions one by one.

摘要： A liquid (2), such as wastewater, is filtered using a liquid-permeable filtering element (9) having first and second faces (10, 11) so as to produce filtered liquid (4) having total suspended solids of no more than 10 mg/L. The method comprises cycling the liquid-permeable filtering element through the liquid whereby, in a first position, an area of the first face of the filtering element is subjected to liquid under pressure and a pressure across the filtering element is greater than 0 and less than or equal to 5.9 kPa (60 cmH2O), and, in a second position, the area is not subjected to liquid under pressure or is subjected to liquid at a lower pressure, and solids accumulated on the first face of the filtering element can be removed by directing at least one jet at the second face of the filtering element through the filtering element towards the first face.
