[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1-4As shown in the figure, the novel ultrafiltration membrane cleaning tank provided by the embodiment of the present utility model includes a high-temperature box 1. Inside the high-temperature box 1, there is a support frame 8 placed. On the inner walls around the high-temperature box 1, mounting frames 9 are fixedly arranged, and several clamping rings distributed up and down are arranged on the mounting frames 9. A coil pipe 10 is arranged on the mounting frames 9 through the clamping rings. The two ends of the coil pipe 10 are respectively provided with a steam inlet pipe 15 and an exhaust pipe 16. On the inner wall of the bottom of the high-temperature box 1, an air distribution pipe 14 is fixedly arranged.

[0022] Specifically, in this embodiment, it includes a high-temperature box 1, which is a closed container composed of steel plates with a certain thickness. High-temperature steam is filled inside it to achieve high-temperature cleaning of the objects inside. Inside the high-temperature box 1, there is a support frame 8 placed. The support frame 8 is used to store ultrafiltration membranes, so that multiple ultrafiltration membranes are neatly placed on the support frame 8. The support frame 8 together with the ultrafiltration membranes can be hoisted into the high-temperature box 1 by an electric hoist. On the inner walls around the high-temperature box 1, mounting frames 9 are fixedly arranged, and several clamping rings distributed up and down are arranged on the mounting frames 9. A coil pipe 10 is arranged on the mounting frames 9 through the clamping rings. The coil pipe 10 is formed by sequentially swirling a single pipe. High-temperature steam is filled inside it and has a heat exchange effect. When the high-temperature steam passes through the inside of the coil pipe 10, heat exchange is realized inside the high-temperature box 1 to heat the inside of the high-temperature box 1. The two ends of the coil pipe 10 are respectively provided with a steam inlet pipe 15 and an exhaust pipe 16. The high-temperature steam enters from the steam inlet pipe 15 and is discharged from the exhaust pipe 16. On the inner wall of the bottom of the high-temperature box 1, an air distribution pipe 14 is fixedly arranged. The high-temperature steam enters the air distribution pipe 14, and high-temperature aeration is realized from below the support frame 8 to achieve high-temperature cleaning operation of the ultrafiltration membranes.

[0023] In the novel ultrafiltration membrane cleaning tank provided by the present utility model, the coil pipe 10 arranged on the inner sides around the high-temperature box 1 can utilize the heat energy dissipated by the coil pipe 10 to realize heat exchange, and high-temperature cleaning of the ultrafiltration membranes above the support frame 8 is achieved from around the support frame 8, improving the cleaning effect of the ultrafiltration membranes. Compared with the traditional high-temperature box, it has a more efficient heat treatment effect. At the same time, the air distribution pipe 14 arranged at the bottom of the high-temperature box 1 can realize high-temperature aeration from below the support frame 8, further improving the cleaning effect of the ultrafiltration membranes.

[0025] A reinforcing plate 3 is fixedly arranged on the outer side of the middle of the high-temperature box 1, and several rib plates 4 are arranged above the outer side of the high-temperature box 1. By using the reinforcing plate 3, the support strength of the high-temperature box 1 is ensured, and it can withstand the strong steam pressure inside it. By using the rib plates 4, the support strength above the steam box can be ensured, improving the use stability of the high-temperature box;

[0026] A cover plate 5 is buckled on the top of the high-temperature box 1, and a first lifting ring 6 is fixedly arranged at the center of the top of the cover plate 5. The cover plate 5 is hermetically buckled above the high-temperature box 1, so as to form a closed cavity in the high-temperature box. The adopted first lifting ring 6 facilitates the opening and closing of the high-temperature box.

[0027] In another embodiment provided by the present utility model, a steam box 7 is arranged on one side of the high-temperature box 1, and the steam box 7 is connected to a steam inlet pipe 15 and a steam outlet pipe 16. By connecting the steam inlet pipe 15 and the steam outlet pipe 16 to the steam box 7, the relatively hot steam inside the steam box 7 enters the inside of the high-temperature box 1 through the steam inlet pipe 15, realizing the heating of the high-temperature box 1. The entire steam after heat exchange flows back into the steam box 7 again through the steam outlet pipe 16, thereby realizing the circulating flow of the steam and realizing the continuous heating operation inside the high-temperature box.
