[0002] The wastewater expansion tank is an essential component of a steam tracing system. Wastewater that has undergone heat circulation is separated into secondary steam and waste hot water in the wastewater expansion tank. The secondary steam can be reused as a heat source in the tracing system, while the waste hot water is discharged. However, in actual use, the following problems often occur with the wastewater expansion tank: the wastewater that has undergone heat circulation contains large particulate impurities that are insoluble in the waste hot water. Over time, these impurities can clog the inside of the wastewater expansion tank, accelerate wear and tear, and reduce its service life.

[0003] To filter out large particulate impurities in the wastewater from the thermal circulation system, a pre-filter is installed at the inlet of the sewage expansion tank. However, the existing pre-filters for sewage expansion tanks are difficult to replace, and it is impossible to determine whether the filter is installed correctly after installation.

[0052] Reference Figures 1 to 8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0053] Specifically, the detection component 203b includes a second spring 203b-1, a square hole 203b-2, and a detection post 203b-3. The square hole 203b-2 is located on one side of the second spring 203b-1, and the detection post 203b-3 is located on one side of the square hole 203b-2.

[0054] It should be noted that one end of the second spring 203b-1 is fixed on the detection component 203b, and the other end is fixed on the rotating component 203d; there are two detection posts 203b-3, and the two detection posts 203b-3 are symmetrical about the square hole 203b-2; the size of the detection posts 203b-3 is adapted to the detection hole 203a-3.

[0055] Furthermore, the locking component 203c includes an arc groove 203c-1, a locking block 203c-2, and a guide post hole 203c-3. The locking block 203c-2 is located on one side of the arc groove 203c-1, and the guide post hole 203c-3 is located on one side of the locking block 203c-2.

[0059] In this embodiment, when the operator wants to install the filter assembly 202, they need to hold the handle 203d-2, align it with the first fixing tube 201c, and insert it, with the fixing ring 202e against the second fixing tube 201d. During insertion, the second fixing tube 201d will squeeze the filter tube 202d, compressing the first spring 202a and causing the support column 202b to penetrate deeper into the second support hole 203a-2b. The penetrated support column 202b will squeeze the detection element 203b, causing the detection column 203b-3 to be gradually... The detection hole 203a-3 is gradually pressed out. Only when the filter tube 202d is pressed tightly enough will the extended support column 202b completely squeeze the detection column 203b-3 out of the detection hole 203a-3. At this time, the operator can turn the handle 203d-2 to drive the locking column 203d-4 to rotate. The rotating locking column 203d-4 will slide along the arc groove 203c-1, causing the locking piece 203c to clamp the locking seat 203a. After this, the operator also needs to insert the card block 203c-2 to complete the locking.
