Description of the principle of online cleaning and dredging: taking four material outlets as an example (or N outlets), the cleaning and dredging principle of each material outlet in the four material outlets is the same, and the online flushing and dredging principle is explained by taking the material outlet 27 in the four material outlets as an example. The material flow of the original valve, pump and pipeline is as follows: the material circulates from the material container 1 → through the first valve 3 → the discharging pump 6 → the second valve 8 → the sixth valve 34 back to the material container 1, and the material can be discharged outwards by opening one or more of the third valve 10, the fourth valve 14, the fifth valve 19 and the N23. Under the condition that the material circulation and material outlet process flow are not changed, the system is additionally provided with a pipeline and a valve for online cleaning and dredging, the position of a material outlet I27 is only provided with a valve III 10, and a valve VI 9, a valve VI 11, a valve VI 12 and a cleaning liquid pipeline are additionally arranged, wherein under the normal condition, the valve VI 9 and the valve VI 11 are in a closed state, and the valve VI 12 is in a communicated state; the front and the back of the discharging pump 6 are only provided with a first valve 3 and a second valve 8, a seventh valve 4, an eighth valve 5 and a ninth valve 7 are additionally arranged, and the seventh valve 4, the eighth valve 5 and the ninth valve 7 are in a closed state under normal conditions; sixteen valves 17 are added in the middle of the circulating pipeline 2, and the pipeline is installed horizontally from the point A to the point B and is installed on the slope with the point A higher than the point B by more than 5%.

The online dredging principle of the valve is as follows: taking the third valve 10 as an example for explanation, the fourth valve 14, the fifth valve 19 and the N23 are the same in principle, and the cleaning liquid pressure is 0.3-0.6 Mpa. In the production process, a high-temperature high-concentration (or saturated) solution easily causes valve blockage, the blockage condition is usually partial blockage or complete blockage, and two online dredging methods are provided for the two conditions.

The on-line dredging method for the blocking condition of the valve part comprises the following steps: during normal production, three 10 parts of the valve are blocked, the machine can be stopped, cleaning and dredging are carried out under the condition of normal production, and the specific operation is as follows: keeping the valve III 10 in a partially blocked state, opening the valve III 9, and because the valve IV 9 and the valve IV 10 are vertically arranged opposite to each other and in the shortest distance, the cleaning liquid vertically acts on the blockage of the valve III 10, the blockage in the valve quickly forms vertical flushing communication on the surface of the partial blockage under the action of the pressure and the solubility of the cleaning liquid, and the partial blockage begins to fall off and is discharged through the material outlet I27 in a short time. In addition, when the cleaning time is long or the cleaning and dredging are relatively difficult, the valve eleven 9, the valve III 10 and the valve twelve 12 can be in an open state, the valve eleven 11 is in a closed state, the handle of the valve III 10 can be wriggled back and forth, the action is changed from small to large, the valve core and a blocking object interact to accelerate loosening and falling through continuous wriggling of the valve core of the valve III 10, and finally the dredging is accelerated.

The condition of three 10 total blockages of valve, when three 10 total blockages of valve have appeared and can not arrange the material when normal production, can wash the mediation under the condition of not shutting down, specific operation is: firstly, opening one or more of a valve four 14, a valve five 19 and a valve N23 to ensure that the production is normally carried out; and then, forward cleaning and dredging are carried out, a valve eleven 9 is opened, cleaning liquid vertically acts on the blockage at the inlet of the valve III 10, meanwhile, the valve eleven 11 can be opened, the valve twelve 12 is opened and closed continuously and quickly, the cleaning liquid cleans and dredges the blockage at the outlet of the valve III 10, the blockage in the valve III 10 is dissolved, loosened and dropped by simultaneously carrying out impact cleaning on the front surface and the back surface of the blockage in the valve III 10, the aim of quickly dredging the valve III 10 is achieved, and finally the cleaning liquid and the dropped objects are discharged from the material outlet I27 (or the material outlet II 28, the material outlet III 29 and the material outlet N30) through the valve III 10 and the valve twelve 12 (or the valve IV 14, the valve V19 and the valve N23).

The online dredging principle of the pump is as follows: according to the technology, the discharge pump 6 is taken as an example (other pumps are the same) to perform online dredging, the discharge pump 6 and an inlet valve and an outlet valve of the discharge pump are blocked to cause material flow to be reduced, the production requirement cannot be met, and the pump and the valve of the pump can be rapidly cleaned and dredged online without disassembling the pump and the valve under the condition of needing dredging. In the online cleaning process, the discharging pump 6 can not feed materials and only can feed cleaning liquid, and the online cleaning and dredging of the pump have the following two types. The first method comprises the following steps: when the discharging is found, part of the discharging pump 6 is blocked, the discharging pump 6 is not required to be stopped, the operation of the discharging pump 6 is kept, and the online cleaning and dredging are completed by switching the valve operation. The specific operation is as follows: opening a valve seven 4, then closing a valve I3, and switching the high-concentration material or the saturated material in the pump into cleaning fluid; the cleaning liquid has pressure and solubility of 0.3-0.6Mpa, and the pressure and flow of the pump act on partial blockage together, so that the partial blockage and the blockage can fall off and be dredged quickly; the valve can be directly switched to produce after the pump is dredged, and the specific operation is to open the first valve 3 and then close the seventh valve 4. The second method is as follows: the method is adopted under the condition that the first method cannot dredge well, and comprises the following specific steps: opening a valve seven 4, closing a valve I3, stopping the operation of a discharge pump 6 after about three minutes, preventing residual materials in a circulating pipe from blocking the circulating pipe and all valves of the circulating pipe, closing a valve six 34 and a valve II 8, then opening a valve nine 7 for reverse cleaning, and opening a valve eight 5 to discharge cleaning liquid and blocking substances; at the moment, the valve eight 5 can be quickly opened and closed, and the blockage is impacted by the pressure of the cleaning liquid, so that the dredging can be accelerated. After the operation is finished, the valve eight 5 can be closed, the valve seven 4 can be opened, and the cleaning liquid simultaneously acts on the front surface and the back surface of the blockage in the discharge pump 6, so that the cleaning and dredging are accelerated; at the moment, the valve eight 5 can be quickly opened and closed, so that the cleaning liquid impacts the blockage, the dredging can be accelerated, and the cleaning liquid and the blockage are discharged through the valve eight 5; after the pump is cleaned and dredged on line, firstly, the valve seven 4, the valve eight 5 and the valve nine 7 are closed, then, the valve I3, the valve II 8 and the valve six 34 are opened, and then, the discharge pump 6 is started to enter a normal production state.
