Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, the spray cleaning device of the present invention comprises a booster pump 11, a sewage suction pump 12, a three-dimensional rotary nozzle 13, a filter a15, a water tank 16, and a filter B22; the closed pipeline is sequentially connected with a booster pump 11, a three-dimensional rotary sprayer 13, a filter A15, a sewage suction pump 12, a water tank 16 and a filter B22, a pressure regulating valve 14 and a pressure gauge 18 are arranged between the booster pump 11 and the three-dimensional rotary sprayer 13, a recovery valve 19 is arranged between the three-dimensional rotary sprayer 13 and the filter A15, the water tank 16 is provided with a liquid level meter 17 and a drain valve 20, and a valve 21 is arranged between the water tank 16 and the filter B22.
The water tank 16 comprises a top plate 1 and a tank wall 5, a water adding cover plate 2 and a vent pipe 3 are arranged on the top plate 1, a liquid level meter connecting pipe 4, a transverse reinforcing angle steel 6, a water pumping hole 7 and a water inlet 10 are arranged on the tank wall 5, and a channel steel 8 and a water outlet 9 are arranged on the lower portion of the water tank 16.
Before the system works, the tightness of the system is firstly checked, all parts of the cleaning system are strictly grounded, the pressure of the system is adjusted through an adjusting pressure regulating valve 14 according to the size of a tank body to be cleaned during initial work, a booster pump 11 is started, whether the cleaning water pressure meets the cleaning requirement is determined by reading the pressure of a pressure gauge 18, the booster pump 11 is stopped after the normal work is confirmed, a valve 21 is opened, the booster pump 11 is started again, cleaning is started, the continuous cleaning process is ensured, the booster pump 11 is closed when the cleaning is finished, a dirt suction pump 12 continues to work, after cleaning liquid in the tank body is sucked dry, the dirt suction pump 12 is closed, residues in a filter B22 are collected after the cleaning is finished, and the.
Before cleaning, the spray head 13 is firstly fixed on the flange above the tank body, so that the sealing performance and the firmness are ensured. And then, filling water into the water tank 16, wherein the water filling amount is 4/5 smaller than the volume of the water tank, starting a system to test the tightness of the pipeline, starting cleaning after the tightness is determined to be good, starting the booster pump 11 and opening the valve 21 during cleaning, and enabling the cleaning liquid to reach a primary filter screen through the cleaning valve to filter impurities in the cleaning liquid. The filtered cleaning liquid enters the booster pump 11, the pressure of the cleaning liquid is increased by the action of the booster pump 11, then the pressure of the liquid is kept at a required pressure value by adjusting the pressure of the pressure regulating valve 14, and the value of the pressure gauge 18 is closely concerned so as to prevent the pressure fluctuation from influencing the normal operation of the cleaning work. The cleaning liquid flowing through the pressure gauge 18 enters the three-dimensional rotating nozzle 13 through the high-pressure hose, and the high-pressure water sprayed by the three-dimensional rotating nozzle is used for cleaning the tank body in all directions. When the liquid level of the water tank drops to about 1/4, the recovery valve 19 at the lower end of the tank body is opened, the sewage suction pump 13 is started, and the recovered liquid enters the sewage suction pump 12 through the secondary filter screen A15 and finally reaches the water tank 16 for circulation. After 3 ~ 5 jar bodies are washd in the circulation, get a small amount of washing liquid through drain valve 20 of water tank bottom and detect, if the liquid dosage exceeds standard, then the circulation that should stop, and the washing liquid of discharging is retrieved, treats next step and handles.
The cleaning nozzle 13 is gamma cleaning 8 type nozzle. The choice of the booster pump 11 is mainly determined by the pressure and flow rate of the nozzle, and the pressure P of the nozzle is 0.5Mpa and 5kg/cm2Selecting the maximum flow rate L as 200L/Min, determining the head H as 50m and the flow rate L as 200L/Min according to the liquid internal pressure formula P as rho gH; the sewage suction pump 12 is selected only to meet the flow demandObtaining the flow rate L of the sewage suction pump 12 as 200L/Min; the power P of the generator set is determined according to the sum of the maximum output power P1 of the booster pump 11 and the maximum output power P2 of the sewage suction pump 12, wherein P is 1+ P2 is 5.5-1.1-6.6 kw; the pressure hose is generally selected by multiplying the system pressure by a safety factor (1.5-3), that is, the pressure of the hose is 1Mpa, and the pressure of the hose is 1Mpa, wherein σ is 1.5, and 0.5 is 0.75 Mpa. The pressure regulating valve 14 and the pressure gauge 18 are selected to have pressure greater than 1 Mpa.
The flow rate of the booster pump 11 is determined according to the purge radius. Na can be added when cleaning the storage tank2CO3So as to achieve the purpose of cleaning. The sewage suction pump 12 is preferably started after the booster pump 11 is started for 1-2 minutes according to the flow condition of the booster pump 11. The cleaning liquid is used for the first time during the initial cleaning, so that the sewage suction pump is not started before the cleaning liquid is used up.
