Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, and more specifically, to a circulating cleaning device. Background Art

[0002] Stirring tanks are used in chemical enterprises to stir and mix materials. A stirrer is installed inside the stirring tank. Usually, after long-term use, it is necessary to clean the stirrer and the inner wall of the stirring tank. However, traditional stirring shafts are all solid shafts, and due to the complex connection relationship between the stirring shaft and the stirring paddle, it makes cleaning very inconvenient.

[0003] For example, a chemical reaction kettle with a circulating cleaning function disclosed in the patent with the publication number CN208512558U uses clean water for circulating cleaning, which is more thorough, saves water resources and reduces the use cost. However, in actual use, a cleaning agent is generally used to clean the kettle body, and then a solvent with a faster evaporation rate (such as ethanol) is used for cleaning after cleaning, so that the kettle body can be put into use again. This reaction kettle can use one of the cleaning agent and the solvent for circulating cleaning through the first water pump, the second water pump and the spray head, and cannot switch between the two, thus affecting the cleaning efficiency of the kettle body.

Sliding grooves are provided on the opposite side walls of the slot 331 along the insertion direction of the plug board 220. Sliding blocks 611 located in the corresponding sliding grooves are provided on the side wall of the plug board 220. Thus, the plug board 220 is inserted and installed in the slot 331. When the plug board 220 is installed at the waste discharge port 601, it can abut against the lower end of the filter element 310 to ensure the sealing performance of the installation of the filter element 310 in the filter housing 200;

[0048] Of course, in order to ensure the stability of the installation of the plug board 220 in the slot 331, a lapping board 612 is provided on the side wall of the plug board 220 located outside the filter housing 200, and the lapping board 612 is detachably installed on the filter housing 200 by screws.

[0049] Combined with Figure 5 As shown, in this embodiment, the positioning member includes a positioning column 510 that can be lifted and lowered in the installation cavity 501. A positioning rod 511 that penetrates through the top cover 210 and extends out is provided on the positioning column 510. A spring 520 for pushing the positioning column 510 to extend and engage in the positioning hole 321 is sleeved on the positioning rod 511 located in the installation cavity 501. A turning member 530 for driving the positioning column 510 to retract is provided at the extending end of the positioning rod 511.

[0050] In this embodiment, a hinge groove 531 for the extending end of the positioning rod 511 to extend into is provided in the turning member 530. A hinge shaft that penetrates through the positioning rod 511 is provided in the hinge groove 531. When the turning member 530 is turned to the horizontal position, it is used to realize the extension of the positioning column 510, and when the turning member 530 is turned to the vertical position, it is used to realize the retraction of the positioning column 510.

[0051] In the actual use of this embodiment, through the arrangement of the hinge groove 531 and the hinge shaft, the hinge connection of the turning member 530 at the extending end of the positioning rod 511 is preferably realized;

[0052] The installation cavity 501 is opened toward the lower side wall of the top cover 210. When the top cover 210 slides into the step groove 301, the flip member 530 is horizontal. Under the action of the spring 520, the positioning column 510 extends out of the installation cavity 501 and is inserted into the positioning hole 321 to fix the top cover 210. At this time, the flip member 530 is arranged in contact with the upper side wall of the top cover 210.

[0053] Among them, one end of the flip member 530 forms a toggle portion, and the other end forms a contact portion. When the toggle portion is toggled to drive the flip member 530 to rotate around the hinge axis, so that the contact portion contacts the upper side wall of the top cover 210, the flip member 530 is in a vertical state. Since the contact portion has a certain length, when it contacts the upper side wall of the top cover 210, it can drive the positioning column 510 to retract into the installation cavity 501, so that it disengages from the positioning hole 321, thereby releasing the fixation of the top cover 210. Therefore, the flip member 530 can be flipped by toggling the toggle portion, so that the top cover 210 can be disassembled and assembled, and the operation is simple and convenient.

[0054] Working principle: By opening and closing the first ball valve 181, the second ball valve 182, the third ball valve 183 and the fourth ball valve 184, the rough washing mother tank 110 and the fine washing mother tank 120 are switched, so that the cleaning agents and solvents in the two enter the stirring kettle 100 in turn, and circulate back to the corresponding switched rough washing mother tank 110 and the fine washing mother tank 120, so that the stirring kettle 100 can be quickly cleaned so that the stirring kettle 100 can be quickly put into use again.

[0055] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
