This invention discloses a reactor for the remediation of carbon and nitrogen metabolism in lake water under low-oxygen conditions. When the riser pipe is filled with water, the water tank, riser pipe, and drain pipe can form a siphon effect. Through the sludge suction port, sludge from the bottom of the reaction chamber is first pumped into the water tank, then raised to the top of the riser pipe, and finally discharged out of the water tank through the drain pipe. The siphon effect can enhance the suction force of the sludge suction port. When the siphon is started, the air-sealing ring first descends to close the air inlet, and then the piston rises. At this time, the one-way diaphragm closes. As the piston rises, the water in the water tank is pushed into the riser pipe by the piston, thereby expelling the air in the riser pipe from the drain pipe, thus starting the siphon. When the piston descends, the one-way diaphragm opens upward to prevent the piston's descent from interfering with the siphon process. When the siphon is stopped, the air-sealing ring rises to allow air to enter the riser pipe, thereby breaking the siphon. Through the cooperation of the air-sealing ring and the piston, the siphon effect can be automatically started and stopped, facilitating the control of the cleaning work.

This invention belongs to the field of drainage equipment technology, and discloses an automatic drainage device and drainage control method for a low-pressure integrated environmental chamber. The device includes: a pressure-bearing drainage tank and an integrated environmental chamber. The drainage channel of the integrated environmental chamber is connected to the inlet of the pressure-bearing drainage tank through a chamber drainage pipe, which is equipped with a chamber drainage valve. The pressure-bearing drainage tank is connected to an anti-clogging self-priming sewage pump through a water tank drainage pipe, which is equipped with a water tank drainage valve. The outlet of the anti-clogging self-priming sewage pump is directly open to the atmosphere. A pressure balance pipe is connected between the pressure-bearing drainage tank and the integrated environmental chamber, and a balance valve is installed on the pressure balance pipe. The pressure-bearing drainage tank is equipped with a water tank pressure relief pipe, which is equipped with a water tank pressure relief valve. Inside the pressure-bearing drainage tank, there are low-level switches, high-level switches, and alarm level switches arranged from low to high. This device does not rely on gravity drainage due to large elevation differences. It achieves stable and reliable drainage within a limited installation space by using a pressure-bearing drainage tank for transition and forced drainage by pump power.

The utility model relates to the technical field of bearing ring detection devices, in particular to a bearing ring detection device for a heat treatment production line. And the U-shaped plate is fixedly installed on the top of the base, a fixing plate is fixedly installed on the open side of the U-shaped plate, and the fixing plate is fixedly installed on the top of the base. The intermittent meshing of the incomplete gear and the gear is controlled by the driving motor, and automatic start and stop of a plurality of to-be-detected bearing rings during conveying can be realized, so that when the bearing rings move, the detection plate can be far away from the to-be-detected bearing rings, otherwise, when the bearing rings stop, the touch switch is turned on, the electromagnet is electrified to repel the magnetic block, and the bearing rings are automatically detected. According to the bearing ring detection device, the detection plate is made to make contact with the to-be-detected bearing rings, at the moment, under measurement of the laser range finder, the effect of automatically and continuously detecting the multiple bearing rings can be achieved, and the detection efficiency of the bearing rings is improved.

The utility model provides an automatic drainage device of an air pump, and relates to the technical field of drainage devices. An inlet pipe is arranged at the lower left position of the air pump machine, the inlet pipe is connected with the top position of a limiting pipe, a conical groove is formed in the lower position in the limiting pipe, a Y-shaped frame is arranged at the lower middle position in the limiting pipe, and a telescopic sensor is fixedly installed in the middle position of the bottom of the Y-shaped frame. When the water level rises to a set height, the floating ball rises to push the plug piece to be separated from the conical groove, the drainage channel is opened, and the air pump is started; when the water level drops, the spring piece resets to drive the plug piece to close the channel, the air pump machine is switched off synchronously, and manual intervention is not needed. The problems that an existing traditional drainage device usually needs to manually monitor the water level and manually start and stop equipment, the automation degree is low, drainage is not timely or excessive, and the applicability and reliability of the device are poor due to the fact that the water level threshold value for triggering drainage cannot be flexibly adjusted according to the water level height requirements of different scenes are solved.

The invention discloses a short-circuit protection testing device and system. The device comprises a main control unit, a relay, a contactor and a communication unit, the relay is electrically connected with the contactor; the relay, the contactor and the communication unit are electrically connected with the to-be-tested equipment respectively; the main control unit is used for controlling on-off of the relay according to the test time sequence; after the relay is closed, the to-be-tested equipment operates under a target working condition, and the contactor controls one field-effect tube of the to-be-tested equipment to be short-circuited so as to realize short-circuit protection test; the communication unit is used for inquiring and sending the current state of the to-be-tested equipment to the main control unit, so that the main control unit determines whether the to-be-tested equipment breaks down or not according to the current state, and the test process is ended when the to-be-tested equipment breaks down. According to the scheme, on-off of the relay can be controlled based on the test time sequence, so that automatic start and stop of test are realized, and equipment damage caused by long-time test is avoided; meanwhile, real-time monitoring of the equipment state can be achieved before testing or in the testing process, invalid testing is avoided, and the testing efficiency is improved.
