[0019] The realization, functional features and advantages of the object of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0020] It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] Refer to Figure 1 , Figure 2 and Figure 3 , the circulating water side filter drainage recovery and reuse device includes a water return device 1. A water pump 2 is arranged inside the water return device 1. A control switch 3 and a water return pipe 4 are arranged on the water return device 1. A filtering structure and a positioning structure are arranged on the water return device 1. One end of the water return pipe 4 penetrates and extends into the interior of the water return device 1. The water pump 2 is fixedly installed inside the water return device 1. The control switch 3 is fixedly installed on the top of the water return device 1.

[0022] In this embodiment, the filtering structure includes a mounting plate 51 fixedly installed on the top of the water return device 1. A connecting bracket 52 is fixedly installed at the bottom of the mounting plate 51, and one end of the connecting bracket 52 penetrates and extends into the interior of the water return device 1. A filter screen 53 for filtering scale precipitates in the water is fixedly installed at the bottom of the connecting bracket 52, which facilitates filtering the water entering the water return device 1. A support assembly 54 for supporting the filter screen 53 is arranged inside the water return device 1. The support assembly 54 includes two support bars, and the two support bars are respectively fixedly installed on the left and right side walls of the inner cavity of the water return device 1. The tops of the two support bars are respectively in contact with the bottom of the filter screen 53, which facilitates supporting the filter screen 53 to withstand the impact of water. A positioning frame 55 is fixedly installed on the top of the mounting plate 51. One end of the return water pipe 4 penetrates the positioning frame 55 and the mounting plate 51. A locking assembly 56 for connecting the water return device 1 is arranged on the mounting plate 51. The locking assembly 56 includes two locking bolts. One end of each of the two locking bolts penetrates the mounting plate 51 and extends into the interior of the water return device 1, and both of the two locking bolts are threadedly connected to the interior of the water return device 1, which facilitates loosening the locking bolts to achieve the disassembly of the mounting plate 51.

[0023] Among them, the connecting bracket 52 includes a rectangular connecting frame and four connecting rods. The four connecting rods are all fixedly installed on the rectangular connecting frame. The four connecting rods are all fixedly installed on the top of the filter screen 53, and the four connecting rods are all fixedly installed on the bottom of the mounting plate 51, which is convenient for taking out the filter screen 53 through the connecting bracket 52 after disassembling the mounting plate 51.

[0024] By adopting the above technical solution, part of the already cooled water enters the interior of the water return device 1 through the return water pipe 4. The scale precipitates in the water are filtered out by the filter screen 53 in the water return device 1, and then the filtered water is pumped back to the water heater for heating by the water pump 2. Moreover, the fixing of the return water pipe 4 can be released by using the positioning structure, and then the staff can pull out the return water pipe 4. By unscrewing the locking bolts in the locking assembly 56, the staff can disassemble the positioning frame 55 and the mounting plate 51, so that the mounting plate 51 takes out the filter screen 53 from the water return device 1 by means of the connecting bracket 52, thereby facilitating the staff to clean the scale precipitates filtered on the filter screen 53.

[0025] In this embodiment, the positioning structure includes two mounting platforms 57, and the two mounting platforms 57 are both fixedly installed on the inner top wall of the positioning frame 55. Electric push rods 58 are fixedly installed on the two mounting platforms 57. The telescopic ends of the two electric push rods 58 are fixedly connected with fixing members 59 for fixing the return water pipe 4, which is convenient for the electric push rods 58 to drive the fixing members 59 to move left and right. The two fixing members 59 both include fixing plates and arc-shaped grooves. The two arc-shaped grooves are respectively opened on the two fixing plates, and the two fixing plates are respectively fixedly connected with the telescopic ends of the two electric push rods 58, which is convenient for clamping and fixing the return water pipe 4.

[0026] Among them, a limiting strip is fixedly installed on the front side wall of the inner cavity of the positioning frame 55, and limiting grooves are formed on the fronts of the two fixing plates. The inner walls of the two limiting grooves are respectively slidably connected to the outer surface of the limiting strip, which is convenient for restricting the movement track of the fixing member 59.

[0027] With the above technical solution, the electric push rod 58 on the installation platform 57 is activated, and the two fixing members 59 are controlled by the two electric push rods 58 to move towards the opposite sides, so as to release the fixation of the return water pipe 4, facilitating the staff to extract the return water pipe 4.

[0028] The working principle of the above embodiment is as follows:

[0029] When the circulating water side filtration drainage recovery and reuse device is in use, part of the already cooled water enters the interior of the water return device 1 through the return water pipe 4. The scale precipitate in the water is filtered out by the filter screen 53 in the water return device 1, and then the filtered water is pumped back to the water heater for heating by the water pump 2. Moreover, the electric push rod 58 on the installation platform 57 can be activated, and the two fixing members 59 are controlled by the two electric push rods 58 to move towards the opposite sides, so as to release the fixation of the return water pipe 4. Then, the staff extracts the return water pipe 4. By unscrewing the locking bolt in the locking assembly 56, the staff can disassemble the positioning frame 55 and the mounting plate 51, so that the mounting plate 51 takes out the filter screen 53 from the water return device 1 by means of the connecting bracket 52, thereby facilitating the staff to clean the scale precipitate filtered on the filter screen 53.
