A hydraulic driving medium is introduced into a treatment process, one machine has multiple purposes, and the pump is arranged outside the tank body so that the interior of the tank body is not electrified, the safety of the device is improved, the structure is simple and the use is convenient.

Description

technical field

[0001] The invention relates to the field of sewage treatment equipment, in particular to a rotating mechanical device in a closed container and a driving method thereof. Background technique

[0002] Rotating machinery is commonly driven by electricity, such as pumps, mixers, etc., which are directly driven by electric motors. However, in a closed container, especially in an explosion-hazardous environment, the motor cannot be placed directly in the container. Alternatively, the motor is placed outside the container, and the transmission support shaft is used to drive the rotating machinery, such as mixers and mud scrapers in closed tank reactors in the sewage treatment industry. One of the shortcomings of these equipment drivers is that they cannot be used in a closed environment; the second is that they may need a long support shaft, which is prone to failure and is often one of the failure points; third, the drive support shaft needs to be sealed when it...

Embodiment 1

[0030] Embodiment 1, when it is necessary to process the sedimentation tank and the integrated closed tank type biochemical device, firstly, the rotating mechanical device 2 adopts a mud scraper, and then the motor pump 4 is started, and the motor pump 4 will take water from the tank body 1 through the water intake pipe 5. The muddy water is then pressurized by the pump 4, and the pressurized muddy water enters the water turbine 3 through the pressurized water pipe 6, and the muddy water that enters the water turbine 3 through the water pressure pipe 6 is discharged back to the tank 1 through the water turbine 3, and the muddy water is discharged in the water turbine 3 When the water turbine 3 rotates by using the reaction force of mud and sewage, the rotation of the water turbine 3 will drive the mud scraper to rotate, thereby forming a cycle, which also serves as the sludge return function, and the external pump also serves as a rotating mechanical drive and an external supply...

Embodiment 2

[0031] Embodiment 2, when stirring or scraping mud in the sludge and other material concentration tanks and concentration tanks, first rotate the mechanical device 2 and use a mixer or a mud scraper, then start the motor pump 4, and the motor pump 4 will pass through the water intake pipe 5 from the tank body The muddy water is taken from 1, and then pressurized by the pump 4. The pressurized muddy water enters the water turbine 3 through the pressurized water pipe 6, and the muddy water that enters the water turbine 3 through the water pressure pipe 6 is discharged back to the tank 1 through the water turbine 3. When discharging sludge and sewage, the water turbine 3 will rotate using the reaction force of the sludge and sewage, and the rotation of the water turbine 3 will drive the mixer or mud scraper to rotate, thereby forming a cycle. The external pump is also used as a rotating mechanical drive and external supply. Machine dual-purpose, no additional equipment.
