[0026] like Figure 1and Figure 2 As shown, the present application provides a sewage heat exchange device, including a box body 1 and a box cover 2. Locking assemblies 3 are arranged on opposite sides of the box body 1. The box cover 2 realizes opening or closing of the box body 1 through the locking assemblies 3. Specifically, the two locking assemblies 3 are symmetrically arranged. When the box cover 2 closes the box body 1, the closing effect is better. The box cover 2 can open the box body 1 through the locking assemblies 3 to expose the internal structure of the box body 1, which is convenient for the staff to regularly flush it with a water gun. A baffle 4 is fixed in the box body 1. The baffle 4 divides the interior of the box body 1 into a filter chamber 5 and a heat exchange chamber 6. A filter assembly 7 is arranged in the filter chamber 5. A heat exchange coil 8 is fixed in the heat exchange chamber 6. Both ends of the heat coil 8 extend to the outside of the box body 1, a sewage input port 9 connected to the filter chamber 5 is provided on one side of the box body 1, a connecting port 10 connecting the filter chamber 5 with the heat exchange chamber 6 is provided on the baffle 4, and a sewage output port 11 connected to the heat exchange chamber 6 is provided on one side of the box body 1. When in use, sewage enters the filter chamber 5 from the sewage input port 9 and then enters the heat exchange chamber 6 after filtration. At the same time, cooling water is input into the heat exchange coil 8. The filtered sewage exchanges heat with the cooling water in the heat exchange coil 8 in the heat exchange chamber 6, and finally flows out from the sewage output port 11, which effectively prevents impurities and sediments in the sewage from accumulating on the surface of the heat exchange coil 8, thereby ensuring the heat exchange effect.

[0027] like Figure 2 As shown, the locking assembly 3 includes a drive box 31, a screw rod 32, a handle 33 and a rod sleeve 34. The drive box 31 is fixedly arranged on the box body 1, and the screw rod 32 is rotatably connected to a side wall of the drive box 31 away from the box body 1. One end of the screw rod 32 extends into the drive box 31 and is threadedly connected to the rod sleeve 34. The other end of the screw rod 32 is located outside the drive box 31 and is fixedly connected to the handle 33. One end of the rod sleeve 34 away from the screw rod 32 movably passes through a side wall of the drive box 31 close to the box body 1. A socket 21 compatible with the rod sleeve 34 is provided on the box cover 2. When the box body 1 is closed by using the box cover 2, the box cover 2 is placed on the top of the box body 1, and then the handle 33 is rotated to rotate the screw rod 32, so that the end of the rod sleeve 34 away from the handle 33 approaches the box body 1 and is inserted into the socket 21, and the box cover 2 and the box body 1 are locked by the two locking assemblies 3.

[0028] like Figure 2 As shown, a stopper 321 is fixedly disposed at one end of the screw rod 32 away from the handle 33 , and the size of the stopper 321 is larger than the width of the opening of the rod sleeve 34 , so as to prevent the rod sleeve 34 from extending excessively and slipping off.

[0029] like Figure 1As shown, the filter assembly 7 includes a first filter cage 71, a second filter cage 72 and a third filter cage 73, which are all hung in the filter chamber 5 to facilitate taking out the first filter cage 71, the second filter cage 72 and the third filter cage 73, wherein the first filter cage 71 is filled with gravel, the second filter cage 72 is filled with asbestos, and the third filter cage 73 is filled with activated carbon. After the sewage enters the filter chamber 5, it passes through the first filter cage 71, the second filter cage 72 and the third filter cage 73 in sequence, thereby removing most of the impurities and sediments in the sewage to prevent it from entering the heat exchange chamber 6 and accumulating on the surface of the heat exchange coil 8.

[0030] like Figure 2 As shown, an elastic sealing rubber ring 12 is provided at the connection between the box cover 2 and the box body 1 to improve the sealing effect between the box cover 2 and the box body 1.

[0031] like Figure 1 As shown, a first sewage pipe 13 communicating with the filter chamber 5 is provided at the bottom of the box body 1, and a first sewage valve 14 is installed on the first sewage pipe 13. By opening the first sewage valve 14, sewage generated during flushing in the filter chamber 5 can be discharged.

[0032] like Figure 1 As shown, a second sewage pipe 15 communicating with the heat exchange chamber 6 is provided at the bottom of the housing 1. A second sewage valve 16 is installed on the second sewage pipe 15. By opening the second sewage valve 16, sewage generated during flushing in the heat exchange chamber 6 can be discharged.

[0033] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
