DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] Please refer to Figures 1-5 A waste heat power generation hot water circulating system, including water storage tank 1, water storage tank 1 back side's upper end is fixedly connected with water inlet flow pipe 3, water storage tank 1 back side's lower end is fixedly connected with water outlet flow pipe 2, the top of water storage tank 1 is hinged with maintenance door 101 near one end of water inlet flow pipe 3, water storage tank 1 bottom is fixedly connected with positioning frame 4 near the position of water outlet flow pipe 2, positioning frame 4's inside is inserted with filter frame 8, filter frame 8 upper end is fixedly connected with upper end filter screen 9 away from the position of water storage tank 1 side wall, and upper end filter screen 9 is matched with water inlet flow pipe 3.

[0024] The waste heat power generation hot water circulating system in the utility model, the water of water inlet flow pipe 3 flows out first is filtered by upper end filter screen 9, then enters water storage tank 1, simultaneously, water flow is not passed through upper end filter screen 9 when entering water outlet flow pipe 2, therefore water flow is not easy to carry impurity and enter water outlet flow pipe 2, reduced the probability that water outlet flow pipe 2 occurs block, simultaneously, filter frame 8 and positioning frame 4 are inserted and connected, when more impurities in upper end filter screen 9 need to be cleaned, just filter frame 8 is pulled out from positioning frame 4, make filter frame 8 and upper end filter screen 9 more easily clean, in addition, the structure of water storage tank 1, water outlet flow pipe 2 and water inlet flow pipe 3 in the utility model is similar with the waste heat power generation hot water circulating system structure disclosed in the patent with the prior art, patent authorized announcement number CN219474315U, so here is not elaborated too much.

[0025] As Figure 2 And Figure 4 Indicated, filter frame 8 lower end is fixedly connected with lower end filter screen 10 near the side of water outlet flow pipe 2, and lower end filter screen 10 is attached with the end of water outlet flow pipe 2.

[0026] Specifically, the water entering the outlet flow pipe 2 is filtered by the lower end filter screen 10, further reducing the probability of impurities entering the inside of the outlet flow pipe 2, and making the outlet flow pipe 2 less likely to be blocked.

[0027] As shown in Figure 2 and Figure 3 , one side of the upper end of the filter frame 8 is provided with a positioning plate 5, and the positioning plate 5 is fixedly connected with the water storage tank 1.

[0028] As shown in Figure 2 , Figure 3 and Figure 5 , the top of the filter frame 8 is provided with a cover plate 11 matched therewith, and the two sides of the cover plate 11 are fixedly connected with limiting blocks 14. The side of the positioning plate 5 close to the cover plate 11 is provided with a right side limiting groove 6 matched with the limiting blocks 14, and the side wall of the water storage tank 1 is provided with a left side limiting groove 7 matched with the limiting blocks 14.

[0029] Specifically, when installing the filter frame 8, the filter frame 8 can be first misaligned with the water inlet flow pipe 3, then the filter frame 8 is moved downward until the upper end filter screen 9 moves below the water inlet flow pipe 3, then the filter frame 8 is pushed horizontally to align with the positioning frame 4, then the filter frame 8 is pushed downward to insert into the positioning frame 4, then the limiting blocks 14 on the left side of the cover plate 11 are aligned with the left side limiting groove 7, and then the cover plate 11 is moved along the left side limiting groove 7 to cover the top of the filter frame 8, thereby limiting the filter frame 8 to avoid self-floating of the filter frame 8, resulting in a decline in the filtering effect of the filter frame 8.

[0030] As shown in Figure 3 , the ends of the right side limiting groove 6 and the left side limiting groove 7 away from the water inlet flow pipe 3 are each provided with a chamfer. The chamfer makes it easier for the limiting blocks 14 to enter the inside of the right side limiting groove 6 and the left side limiting groove 7.

[0031] As shown in Figure 2 , Figure 3 and Figure 5 , the bottom of the side of the cover plate 11 close to the water inlet flow pipe 3 is fixedly connected with a protective plate 12, and the protective plate 12 is provided with a positioning hole 13 matched with the water inlet flow pipe 3.

[0032] Specifically, after the cover plate 11 covers the top of the filter frame 8, the protective plate 12 will be attached to the side wall of the water storage tank 1, thereby avoiding impurities adhering to the side wall of the water storage tank 1, making it difficult to clean the water storage tank 1.

[0033] As shown in Figure 5 , the top of the cover plate 11 is provided with a gripping groove 15. Moving the cover plate 11 through the gripping groove 15 is more labor-saving and convenient.

[0034] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application.
