[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0035] In one embodiment of the present invention, a stirring and cleaning device for a tank is provided. Figure 1 As shown, the stirring and cleaning device comprises:

[0036] The screw rod assembly includes a vertically arranged screw rod 110 and a first fixing bracket 120 sleeved outside the screw rod 110, the screw rod 110 is made of stainless steel, and a vertical strip-shaped guide hole is provided on the first fixing bracket 120;

[0037] A stirring assembly, comprising a stirring head 210 and a second fixed bracket 220 arranged above the stirring head 210, wherein the stirring head 210 is provided with a water inlet and a plurality of water outlet nozzles 212 which are interconnected, and the water outlet nozzles 212 are arranged on the side of the housing of the stirring head 210;

[0038] A connecting assembly, comprising a cross bar 310 and a nut 320, wherein the nut 320 is sleeved on the screw rod 110, one end of the cross bar 310 is fixedly connected to the nut 320, and the other end thereof passes through a guide hole on the first fixing bracket 120 and is fixedly connected to a side surface of the second fixing bracket 220;

[0039] The power assembly includes a first power mechanism and a second power mechanism, wherein the first power mechanism is configured to drive the screw 110 to rotate, and then the connecting assembly drives the stirring assembly to move up and down along the direction of the guide hole; specifically, the first power mechanism includes a motor 412 and a reducer 414, and the input shaft of the reducer 414 is connected to the output shaft of the motor 412; the top end of the screw 110 is connected to the output shaft of the reducer 414, and when the output shaft of the motor 412 rotates, the screw 110 rotates around the central axis of its own length direction. At this time, the vertical bar-shaped guide hole on the first fixed bracket 120 restricts the cross bar 310 from rotating, so that the nut 320 moves up or down along the screw 110, causing the stirring assembly (second fixed bracket 220) to move up and down.

[0040] like Figure 1 As shown, the second power mechanism includes an air pump 422, a water pump 424 and a pipeline 426, wherein the outlets of the air pump 422 and the water pump 424 are both connected to one end of the pipeline 426, and the other end of the pipeline 426 is connected to the water inlet of the mixing head 210, and the air supply of the air pump 422 and / or the water supply of the water pump 424 drive the water outlet nozzle 212 of the mixing head 210 to rotate relative to the second fixed bracket 220. The air pump 422 is connected to the pipeline 426 through the air inlet electric butterfly valve 421 and the first check valve 423; the water pump 424 is connected to the pipeline 426 through the water inlet electric butterfly valve 425 and the second check valve 427.

[0041] In one embodiment of the present invention, the second power mechanism further comprises a hose reel 428, and a portion of the pipe 426 is wound around the hose reel 428. Thus, as the stirring assembly moves upward, the pipe 426 can increase the length of the hose reel 428; as the stirring assembly moves downward, the pipe 426 can be released from the hose reel 428.

[0042] As described above, the water outlet nozzle 212 of the mixing head should rise / fall synchronously with the second fixed bracket 220, and also have the ability to rotate relative to the second fixed bracket 220. In a specific embodiment: Figure 2As shown, the stirring head 210 includes a cover 214 and a body 216. The cover 214 is disposed above the body 216, and a bearing is disposed between the cover 214 and the body 216 so that the body 216 can rotate relative to the cover 214. The lower end of the second fixing bracket 220 is fixedly connected to the cover 214. The body 216 is provided with a cylindrical side surface, and the water outlet nozzle 212 is disposed on the side surface of the body 216.

[0043] The stirring head 210 is provided with a receiving cavity, the second fixing bracket is a hollow structure, and the pipeline 426 of the second power mechanism passes through the second fixing bracket and is connected with the water inlet.

[0044] See also Figure 2 The number of the cross bars 310 and the nuts 320 is more than two and corresponds to each other. The multiple cross bars 310 are fixed at different heights of the second fixing bracket 220, which can increase the installation stability of the stirring assembly.

[0045] According to another aspect of the present invention, a sodium hypochlorite stock solution storage device is provided, such as Figure 3 As shown, the storage device includes a raw liquid tank 500 and the stirring and cleaning device as described above. Figure 3 This is only a schematic diagram of arranging the stirring and cleaning device in the raw liquid tank 500, and is not intended to be used as a reference. Figure 3 Limit the size ratio between the two.

[0046] The entire contents of the above stirring and cleaning device embodiment are incorporated into this sodium chlorate stock solution storage device embodiment by reference and will not be repeated here.

[0047] During the process of injecting sodium hypochlorite stock solution into the stock solution tank 500, the air pump 422 and the water pump 424 of the second power mechanism can be started. Under the action of the high-pressure gas, on the one hand, the stirring head 210 rotates, and the water outlet nozzle 212 can be used as a stirring blade, or a stirring blade can be provided separately; on the other hand, under the action of the high-pressure gas, the liquid in the pipeline 426 is quickly sprayed out from the water outlet nozzle 212, so as to flush the side wall of the stock solution tank 500.

[0048] In addition, the lifting height of the stirring assembly can be adjusted by starting the first power mechanism. For example, by controlling the motor 412 to rotate forward, the stirring head 210 can be controlled to rise, and by controlling the motor 412 to rotate reversely, the stirring head 210 can be controlled to descend. In this way, the first power mechanism can be used to flush different height areas of the side wall of the raw liquid tank 500.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0050] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
