The stainless pulse silt-removal water-distribution device disclosed by the invention requires that the upper cover and the rotary body easily rotate around the mandrel, the rotary body is not scratched with the base, the valve body, the valve core, the water-distribution pipe, the upper cover, the rotary body and the base are manufactured by adopting metal materials, and an overflowing surface is coated with PTFE (Polytetrafluoroethylene) materials; and the water-distribution pipe and the water-distribution head of a small-sized water circulation cooling tower are directly manufactured by adopting the PTFE materials.

The invention discloses a water conservancy anti-blocking and dredging device, which comprises a pipeline, a filter screen is fixedly installed in the pipeline, an installation opening is opened on the outer wall of the pipeline, a frame body is fixedly connected in the installation opening, and a frame body is fixedly connected to the frame body. The middle part of the body is equipped with a pulley one, and the outer wall of the pulley one is fixedly connected with a scraper in contact with the outer wall of the filter screen. A method for using a water conservancy anti-blocking and dredging device, comprising the following steps: S1, installing a frame in a pipeline, a switch is connected to an electromagnet, a motor and a valve through a wire, and the wire is connected to an external power supply but the power supply is not powered. The invention automatically presses the switch when there is a lot of silt in the pipeline to block the filter screen, so that the electromagnet and the motor are energized to start working, the electromagnet generates magnetism to push the baffle up, and the motor drives the scraper to rotate to realize the scraping of the silt and cause Centralized collection in the pit body realizes the automatic removal of silt and solves the problem of blockage caused by too much silt in the pipeline.

The invention relates to a maximum output automatic dredging control method of a cutter suction dredger, which belongs to the technical field of automatic control of engineering ships. In any automatic dredging mode, the dredging control system of the cutter suction dredger is based on working conditions. Calculate the critical flow rate of the pipeline through the estimator, and jointly control the cutter motor, traverse winch, bridge winch, steel pile trolley, vacuum release valve and other cutter suction dredger dredging equipment to realize the dredger automatically according to the construction process. For excavation operations, under the premise of ensuring that the flow rate of the pipeline is greater than the critical flow rate, the traverse speed should be increased as much as possible, so as to achieve automatic dredging with maximum output. The invention significantly improves the actual production process of the dredger, can greatly reduce the labor load of dredging operators, reduce the differences in operations among different operators, improve construction quality, ensure equipment safety, and reduce fuel consumption.

In order to solve the above technical problems, an intelligent automatic stomach cleaning equipment for emergency departments, including a box body, a double-acting diaphragm pump, a pipeline conversion anti-blocking device, and other devices are installed through the box body, and the double-acting diaphragm pump provides high-efficiency, Safe, low-energy-consumption positive and negative pressure supply, pipeline switching anti-clogging device realizes automatic switching and distribution between different pipelines and automatic dredging when pipelines are blocked, realizing functionally safe, intelligent and highly automated gastric lavage function. It is characterized in that: the double-acting diaphragm pump is installed and fixed on the box body, and the pipeline conversion anti-clogging device is rotatably installed on the box body.

The invention discloses an automatic dredging and clear water pool of a sandstone production wastewater treatment system and a method for using it, comprising: a clear water pool body, a main water pipe installed at the bottom of the clear water pool body, a water branch pipe connected to the main water pipe, a main water pipe and a water tank. There is a distance between the branch pipe and the inner wall of the clear water tank body. The water branch pipe is provided with a water inlet hole. The flow rate of water pipe drainage is Q=300m 3 / h, clean water is discharged through the main water pipe at a flow rate of 1.2m / s; greater than the settling velocity of the largest solid particle of 0.07m / s, the settling velocity of solid particles in the clean water tank as a whole is much lower than the water flow velocity, ensuring that the entire production The bottom water of the clear water tank body has no dead angle in the flow, and the suspended matter does not sink to the bottom, so as to realize automatic dredging, which solves the problem that sedimentation occurs in the clear water tank of the existing sand and gravel production wastewater treatment system to block the water inlet of the pipeline pump.

The invention relates to an automatic feeding and dredging system for waste gas treatment catalysts. A feeding trolley can move along a feeding track to enter or withdraw from a catalyst dredging device. The catalyst dredging device comprises a left-right travelling mechanism, front-back travelling mechanisms, lens lifting mechanisms and dredging head feeding mechanisms. The left-right travellingmechanism comprises a fixed lead screw and a plurality of first nuts. The first nuts sleeve the fixed lead screw in a left-right spaced mode. The front-back travelling mechanisms comprise rotating lead screws and second nuts sleeving the rotating lead screws. The rotating lead screws rotate under power drive, and drive a vertical mounting base to move forwardly and backwardly through the second nuts. Each lens lifting mechanism comprises a first gear and rack mechanism and a camera. Each dredging head feeding mechanism comprises a second gear and rack mechanism and a dredging component. The automatic feeding and dredging system has the advantages that through independent control of each front-back travelling mechanism, each dredging component and each camera are driven independently, so that blocked portions of honeycomb ducts can be positioned by camera shooting and then dredged automatically, and automatic feeding can be achieved.
