The utility model provides a vortex brush and vortex washing flushing-down type closestool which comprises a bedpan, a dirt collecting well arranged at the bottom of the bedpan and a blow-off pipe communicated with the dirt collecting well, a water supply port is formed in the vertical face of the edge of the right side of the bedpan, and a water sliding face is arranged in the bedpan. A wedge flow face, a turning bank and a speed reduction bank are arranged on a water sliding face on the left side of the bedpan from front to back around a sewage collection well opening, the wedge flow face is arranged at the position, guided into the sewage collection well opening, of the turning bank, and a large water flow supplied to the bedpan through the water supply port is turned back by the turning bank and guided into the sewage collection well. One part of the water flow is blocked by the speed reduction ridge and then guided into the sewage collecting well along the rear portion of the water sliding face to form a flushing flow column, the other part of the water flow is wedged into the sewage collecting well through the wedge flow face to form spiral flushing flow, and the flushing flow column is rolled by the spiral flushing flow in the tangential direction to rotate, so that the purpose of rotatably scrubbing the inner wall of the sewage collecting well is achieved; and the speed of the water flow of the sewage collecting well entering the blow-off pipe is delayed, the water level of the sewage collecting well is quickly raised, and sewage in the sewage collecting well is pressed out of the blow-off pipe under the action of gravity to be discharged.

The invention relates to the technical field of enzyme preparation separation, and discloses an easy-to-clean enzyme preparation separation device which comprises a box body, a reciprocating mechanism is arranged at the top of the box body, an opening and closing mechanism is arranged in the reciprocating mechanism, a stirring mechanism is arranged at the top of the reciprocating mechanism, and a transmission mechanism is arranged at the top of the stirring mechanism. A separating mechanism is arranged at one end of the reciprocating mechanism, a sewage discharging mechanism is arranged on the inner wall of the separating mechanism, and a cleaning mechanism is arranged in the box body. The cleaning mechanism comprises a pump body, and the outer portion of the pump body is fixedly connected to the inner wall of the box body. By adopting the technical scheme of precise filtering of the filter screen, efficient cleaning of the cleaning mechanism, detachable design of the filter screen and timely pollution discharge of the pollution discharge mechanism, the technical effects of good separation effect and rapid cleaning are achieved, and compared with the technical scheme of incomplete filtering and complex cleaning in the prior art, the problems of low separation efficiency and difficult cleaning and maintenance of existing equipment are solved.

The utility model relates to a cleaning device and cleaning equipment, the cleaning device comprises a sewage tank used for collecting sewage, the sewage tank comprises a tank body, and the tank body is provided with a sewage cavity used for containing sewage and a sewage outlet communicated with the sewage cavity; the sealing structure is movably arranged on the box body and is used for sealing the drain outlet; and the driving structure is connected with the sealing structure and can drive the sealing structure to be close to or far away from the drain outlet so as to seal or open the drain outlet. The sealing structure is movably arranged on the box body, the driving structure is used for driving the sealing structure to seal or open the drain outlet, the structure is simple, and the operation is convenient.
