[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0023] Combine Figure 1 and Figure 3 A cleaning structure for an extractive distillation tower includes an extractive distillation tower body 1, a water tank 2 is provided on one side of the extractive distillation tower body 1, a cleaning component 3 for cleaning the extractive distillation tower body 1 is provided on the top of the water tank 2, a support leg 25 is fixedly connected to the bottom end of the water tank 2, and a filtering component 4 for filtering sewage is provided inside the water tank 2.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example 1:

[0026] See also Figure 2-Figure 6The filter assembly 4 includes a filter plate 41, a filter hole 42 opened on the outer surface of the filter plate 41, a groove 43 opened on one side of the filter plate 41, a filter cotton 44 arranged inside the groove 43, a first connecting plate 45 fixedly connected to the top of the filter plate 41, and a second connecting plate 46 fixedly connected to the top of the first connecting plate 45. The bottom end of the second connecting plate 46 contacts the top of the water tank 2. A locking bolt 461 is threadedly connected between the second connecting plate 46 and the water tank 2. The filter hole 42 is connected to the groove 43. The filter hole 42 is opened on the outer surface of the filter plate 41, allowing Water flows through while blocking larger particles. The sewage on the outer surface of the filter plate 41 contacts the filter cotton 44 placed in the groove 43. The filter cotton 44 is used to further filter out fine impurities and pollutants in the sewage. The filtered water is easy to reuse, thereby reducing the demand for fresh water and saving water resources. The second connecting plate 46 is fixed to the water tank 2 by the locking bolt 461. Removing the locking bolt 461 makes it easy to separate the second connecting plate 46 and the water tank 2, thereby facilitating the cleaning of the filter plate 41 and the replacement of the saturated filter cotton 44.

[0027] A first through opening 21 and a second through opening 22 are provided at the top of the water tank 2, and a first mounting groove 23 and a second mounting groove 24 are provided at the bottom of the water tank 2. The first through opening 21 and the first mounting groove 23 are correspondingly arranged, and the second through opening 22 and the second mounting groove 24 are correspondingly arranged. The filter plate 41 movably passes through the first through opening 21 and is engaged with the first mounting groove 23. In the initial state, the filter plate 41 is engaged with the first mounting groove 23, which is convenient for intercepting and filtering clean sewage. By setting the first through opening 21 and the first mounting groove 23, the filter plate 41 can be easily removed from the inside of the water tank 2: the filter plate 41 can be removed along the first through opening 21 by pulling up the second connecting plate 46, which simplifies the disassembly process. After cleaning the filter plate 41, the filter plate 41 is reinserted into the first through opening 21 and engaged with the first mounting groove 23, so as to restore it to its initial state.

[0028] A baffle assembly 5 is provided above the second mounting groove 24. The baffle assembly 5 includes a baffle body 51 that movably passes through the second opening 22, a fixing plate 52 fixedly connected to the top of the baffle body 51, and a handle 53 fixedly connected to the top of the fixing plate 52. The fixing plate 52 is provided corresponding to the second mounting groove 24. When the filter plate 41 needs to be pulled out for cleaning, the handle 53 is pressed downward to drive the fixing plate 52 to move downward so that the fixing plate 52 is engaged with the second mounting groove 24. At this time, it is convenient to block sewage and prevent sewage from affecting cleaning water.

[0029] A first sealing gasket 231 is fixedly connected to the top of the first mounting groove 23, and a second sealing gasket 241 is fixedly connected to the top of the second mounting groove 24. The first sealing gasket 231 and the second sealing gasket 241 facilitate effectively filling the tiny gaps between the first mounting groove 23 and the second mounting groove 24 and the filter plate 41 and the baffle body 51 to prevent sewage from passing through these gaps.

[0030] The cleaning assembly 3 includes a water pump 31 fixedly connected to the top of the water tank 2, a first connecting pipe 32 fixedly connected to the input end of the water pump 31, a second connecting pipe 33 fixedly connected to the output end of the water pump 31, a diverter plate 34 fixedly connected to one end of the second connecting pipe 33, and a cleaning nozzle 35 fixedly connected to one end of the diverter plate 34. The first connecting pipe 32 is fixedly passed through the water tank 2, and the second connecting pipe 33 is fixedly passed through the extractive distillation tower body 1. When the water pump 31 is started, under the action of the water pump 31, the water inside the water tank 2 flows into the diverter plate 34 through the first connecting pipe 32 and the second connecting pipe 33 in turn. The diverter plate 34 evenly distributes the water flow to each cleaning nozzle 35, and the cleaning nozzle 35 sprays high-pressure water to flush and clean the inside of the extractive distillation tower body 1.

[0031] A water inlet is provided at the top of the water tank 2, and a sealing cover 26 is movably connected inside the water inlet. A drain pipe 6 is fixedly connected between the extractive distillation tower body 1 and the water tank 2. Opening the sealing cover 26 facilitates timely replenishment of clean water into the water tank 2. The sewage after cleaning the extractive distillation tower body 1 flows into the water tank 2 through the drain pipe 6 and is filtered and cleaned under the action of the filter component 4.

[0032] During use, the water pump 31 is started. Under the action of the water pump 31, the water in the water tank 2 flows into the diverter plate 34 through the first connecting pipe 32 and the second connecting pipe 33 in sequence. The cleaning nozzle 35 sprays high-pressure water to rinse and clean the interior of the extractive distillation column body 1. The cleaned sewage flows into the water tank 2 through the drain pipe 6. At this time, the filter holes 42 allow water to pass through while blocking larger particles. The sewage passing through the outer surface of the filter plate 41 contacts the filter cotton 44 placed in the groove 43. The filter cotton 44 is used to further filter fine impurities and pollutants in the sewage. The filtered water can be reused, saving water resources. When it is necessary to remove the filter plate 41 for cleaning, the handle 53 is pressed downward to move the fixing plate 52 downward so that the fixing plate 52 is engaged with the second mounting groove 24. This effectively blocks the sewage and prevents it from affecting the cleaning water. The locking bolt 461 is removed, and the second connecting plate 46 is pulled upward to remove the filter plate 41 along the first opening 21, thereby facilitating the cleaning of the filter plate 41 and the replacement of the saturated filter cotton 44.
