Detailed Description
The invention relates to a device for disinfecting and cleaning a water tank for storing water in a secondary water supply system. At the input end for supplying washing agent, the water supplied by municipal pipe network is introduced into the pressurized water pump, and the water pumps are actively regulated to operate in cooperation under the frequency conversion and power frequency states according to the change of water consumption, so as to ensure that the water supply is maintained at higher pressure. The water from the pressurizing water pump flows into the first jet pump, the high-speed water flows into the suction chamber from the nozzle and then sucks the washing agent, and momentum, energy and mass exchange is carried out in the throat pipe to achieve the purpose of fully mixing the agent and the water. The mixed high-speed flowing liquid passes through the diffusion pipe, the kinetic energy is converted into pressure energy and finally discharged, the pressure energy is input into the automatic cleaner through the pipeline, the automatic cleaner rotates at a uniform speed in all directions and sprays high-pressure water columns to knock off impurities such as dirt, moss and the like adhered to the inner wall of the water tank.
Further, the control valve of the first jet pump is closed, the channel for water flow transmission is changed, and the water flow directly flows into the automatic cleaner from the cleaning pipeline. The water tank which is cleaned by the chemical agent and used for the dosing washing pipeline is cleaned for the second time, and the residual chemical agent in the first time of washing can be fully cleaned.
Further, the waste liquid of the two-time washing is discharged through the sewage draining passage. The second jet pump is installed at the sewage draining outlet, the performance of air and liquid can be pumped by the jet pump, the drainage of waste water can be accelerated, and residual air-liquid mixture can be pumped completely even if gas exists in the final stage of sewage draining.
The invention will be further described with reference to the accompanying drawings.
One embodiment of the present invention is shown in fig. 1 and 2. When cleaning, firstly, water introduced into the municipal pipe network A is pressurized through the pressurizing water pump 6, and the output high-speed water flow enters the dosing channel D-1 to be used as the high-pressure working water flow E of the first jet pump 4. The working water flow E enters a nozzle 11 of the first jet pump 4, and then enters a throat 13 after being accelerated through the nozzle 11, at the moment, a dosing valve 8 is automatically opened, detergent in a dosing chamber 3 is sucked by utilizing the shearing and turbulent diffusion effects of jet flow, the detergent enters a suction chamber 12 through a suction inlet F, two flows are fully mixed in the throat 13 and exchange energy, then the pressure is increased through a diffusion pipe 14, and the mixed fluid G flows out of the first jet pump 4 and is conveyed to an automatic cleaner 2 to carry out the all-dimensional high-pressure flushing water tank 1 (with a water outlet C). Meanwhile, the washed sewage passes through the drain valve 9 and is quickly discharged from the drain outlet B through the suction action of the second jet pump 5. And after the first round of adding the medicament and washing is finished, starting the second round of washing operation by using clean water. At this time, the electric valve 10 is closed, and the dosing washing pipeline is closed; and opening the cleaning valve 7, opening the cleaning pipeline D-2, starting the second jet pump 5 to operate, flushing the first round of dosing and washing residues to be flushed clean by the second round of flushing operation, and finally discharging waste liquid from the sewage discharge pipeline D-3 through the sewage discharge valve 9.
In conclusion, the invention utilizes the high-efficiency mixing characteristic of the throat pipe of the jet pump to obviously improve the mixing uniformity of the medicament and the water without manual operation. And meanwhile, two paths of dosing washing and clear water washing are adopted, so that residual agents in the first washing can be sufficiently washed.
