The application relates to a water conservancy ditch sludge treatment device and a treatment method thereof, which comprises a sludge collecting mechanism for collecting and flocculating sludge, a mechanical extrusion mechanism for extruding flocculated sludge water and forming a mud cake to discharge free water in the sludge, and an electro-osmotic water filtering mechanism for continuously filtering water in the ice by the electro-osmotic mode to discharge bound water in the mud cake. The mechanical extrusion mechanism comprises a filter chamber for extruding water after collecting flocculated sludge water, a collecting assembly for collecting water at the bottom of the filter chamber, and a judging assembly for monitoring the flow rate of the mechanical extrusion water. If the flow rate is lower than a preset threshold value, it is determined that mechanical dewatering reaches the limit, the mechanical filter chamber bottom water outlet is closed, and the electro-osmotic water filtering mechanism is opened. The mechanical extrusion and the electro-osmotic mode are matched with each other, the effect of fully discharging sludge water is realized, and the efficiency of sludge recycling is improved.

The utility model discloses a cotton stalk pulping material preparation system, relates to the technical field of papermaking, and mainly aims to remove impurities and provide qualified cotton stalk material sheets. According to the main technical scheme, the cotton stalk pulping material preparation system comprises a grass chopping mechanism, a belt conveyor and an impurity removing mechanism which are connected in sequence; an inlet of the first fan is connected to a discharging port of the impurity removal mechanism, an outlet of the first fan is connected to a tangential inlet of the first cyclone separator, an outlet in the upper end of the first cyclone separator is connected to an inlet of the second fan, and an outlet of the second fan is connected to a tangential inlet of the second cyclone separator. An upper end outlet of the second cyclone separator is connected to an inlet of the third fan, an outlet of the third fan is connected to an inlet of the spraying dust removal tower, and a lower end outlet of the second cyclone separator is connected to the collecting bin; and an outlet at the lower end of the first cyclone separator, the roller type grass washer and the inclined spiral dehydrator are connected in sequence.

The present application belongs to the technical field of sludge dewatering, and discloses a novel automatic sludge unloading sludge compression dewatering machine. The novel sludge dewatering machine is composed of two mirror-symmetrical sludge compression cylinder bodies. One end of the cylinder body is open and provided with a hydraulic sealing plug. The concave opening of the hydraulic sealing plug is provided with a water filter plate. The two symmetrical cylinder bodies are connected by a left-right compression cylinder connecting piston. The maximum travel of the movable piston in the two compression cylinder bodies is the length of the compression cylinder body. In the present application, the two cylinder bodies are intermittently fed by sludge pumps to provide a set pressure for compressing and dewatering the sludge to realize continuous feeding. When the sludge compressed and dewatered in the compression cylinder started first reaches the full cylinder, the sludge feeding direction is switched, and the hydraulic sealing plug on the side where the dewatering is completed is retracted to expose the cylinder body unloading port. Then, the sludge pump on the other side feeds to generate pressure to move the left-right compression cylinder connecting piston between the two cylinder bodies to complete the sludge unloading on the dewatering side, thereby realizing automatic unloading.

The application discloses a kind of edible fungi processing dehydrator, belong to the technical field of dehydrator.It includes shell, the shell upper end is rotatably connected with end cover, and the shell is rotatably connected with two electric cylinders between end cover, the end cover is fixedly installed with electric heating type air blower equipment by bolt, the shell is installed with rotating mechanism, for centrifugal type rotation installation dehydration cylinder, the dehydration cylinder is rotated at high speed in shell, so that the moisture of edible fungi inside dehydration cylinder is thrown out by centrifugal, cooperate the air blowing of electric heating type air blower equipment and can quickly realize the dehydration of edible fungi and utilize hot air blow dry purpose, dehydration cylinder can be hand-held lifting handle along drive rod insertion installation shell, only need to use lock rod locking drive rod and lifting handle, dismounting is convenient, dehydration efficiency is greatly improved, and dehydration cylinder is rotatably arranged on the three E-shaped frames along circumference, and each is equipped with cleaning strip, can realize automatic cleaning effect to shell inner wall, reduce the maintenance cleaning work of shell inner wall.
