Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 As shown, a waste membrane element cleaning and soaking device includes a soaking tank 17. Buried guide rails 19 are provided on both the left and right sides of the soaking tank 17. A guide rail gantry crane 13 is slidably connected to the two buried guide rails 19. A drain basket 14 is provided on the hook of the guide rail gantry crane 13. The membrane element 16 is located inside the drain basket 14. A first tap water inlet pipe is provided on the side of the soaking tank 17, with the outlet of the first tap water inlet pipe facing the inside of the soaking tank 17. A first tap water inlet valve 15 is provided on the first tap water inlet pipe. A mixing component communicating with the soaking tank 17 is provided on one side of the soaking tank 17.

[0018] In this embodiment, the mixing assembly includes a mixing tank 1. An acid storage tank 4 and an alkali storage tank 5 are provided on one side of the mixing tank 1. The acid storage tank 4 and the alkali storage tank 5 are respectively provided with an acid guide pipe and an alkali guide pipe that communicate with the upper side of the mixing tank 1. An acid storage tank outlet valve 3 and an alkali storage tank outlet valve 6 are respectively provided on the acid guide pipe and the alkali guide pipe. A second tap water inlet pipe is provided at the upper end of the side of the mixing tank 1. The second tap water inlet pipe communicates with the interior of the mixing tank 1, and a second tap water inlet valve 12 located outside the mixing tank 1 is provided on the second tap water inlet pipe. A stirrer 10 is provided on the upper side of the mixing tank 1. The stirring end of the stirrer 10 is located inside the mixing tank 1. A conveying assembly for conveying acid solution or alkali solution to a soaking tank 17 is provided on one side of the mixing tank 1.

[0019] In this embodiment, the conveying assembly includes a conveying pipe and a conveying pump 7. The two ends of the conveying pipe are connected to the lower end of the mixing tank 1 and the upper end of the soaking tank 17, respectively. The conveying pipe is equipped with a conveying pump 7 and a mixing tank outlet valve 8.

[0020] In the embodiment, the acid electromagnetic flowmeter 9 and the alkali electromagnetic flowmeter 11 are arranged on the acid pipe and the alkali pipe respectively.

[0021] In the embodiment, the mixing tank 1 is provided with a mixing tank blowdown pipe which is in communication with the inside of the mixing tank 1, and the mixing tank blowdown valve 2 is arranged outside the mixing tank 1.

[0022] In the embodiment, the soaking tank 17 is provided with a soaking tank blowdown pipe which is in communication with the inside of the soaking tank 17, and the soaking tank blowdown valve 18 is arranged outside the soaking tank 17.

[0023] The working principle of the technical solution is as follows: when the waste membrane element cleaning and soaking device works, the pollution type of the membrane element 16 should be determined first, so that the content and type of the reagent are confirmed, then the staff opens the second tap water inlet valve 12 to deliver tap water into the mixing tank 1, then opens the alkali storage tank outlet valve 6 or the acid storage tank outlet valve 3 according to the confirmed reagent amount, and monitors and controls the amount of the acid solution or the alkali solution through the acid electromagnetic flowmeter 9 and the alkali electromagnetic flowmeter 11, then controls the stirrer 10 to stir the acid solution or the alkali solution in the mixing tank 1 uniformly, which solves the problems of inaccurate and uneven reagent configuration and reagent spatter, can accurately configure the soaking reagent according to the proportion, and improves the configuration efficiency.

[0024] When cleaning and soaking, the drip basket 14 is hoisted to the surrounding open area by the guide rail gantry crane 13, then the membrane element 16 is put into the drip basket 14, then the drip basket 14 is hoisted into the soaking tank 17 by the guide rail gantry crane 13, then the mixing tank outlet valve 8 is opened, and the delivery pump 7 is started to deliver the acid solution or the alkali solution in the mixing tank 1 into the soaking tank 17 and completely immerse the drip basket 14, which solves the problems of heavy loading and too close contact of the waste membrane element 16 during loading and unloading, and the drip basket 14 is provided with an upper cover to avoid uneven soaking caused by the floating of the dry membrane element 16 in the initial soaking stage.

[0025] When the soaking is finished, the staff controls the guide rail gantry crane 13 to hoist the drip basket 14 above the soaking tank 17 for water dripping, then controls the first tap water inlet pipe to flush the residual reagent on the surface of the membrane element 16 through the first tap water inlet valve 15, and then the drip basket 14 is hoisted to the open area by the guide rail gantry crane 13 to unload the membrane element 16 to the cleaning area, which solves the problem of residual reagent on the surface of the membrane element 16 after soaking, which may cause secondary damage, and the operation of carrying the membrane element 16 is changed from the soaking tank 17 to the ground platform, which not only reduces the operation risk.

[0026] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
