[0001] The utility model relates to the technical field of boiler condensate filtration, and more specifically, to a boiler condensate filtration device with an anti-blocking function. Background Technique

[0002] Iron removal is an important link in the steam condensate treatment process. During the process of using a condensate iron removal filtration device for iron removal, the condensate iron removal filtration device may be blocked due to the accumulation of impurities such as rust, which may further lead to a decrease in the flow rate of the condensate or even complete blockage, thus affecting the iron removal effect and the normal operation of the equipment.

[0003] After retrieval, the utility model patent with the publication number of CN221319565U discloses a condensate iron removal filtration device, including a tank body. The upper end of the left end of the tank body is fixedly installed with a condensate inlet, and the lower end of the right end of the tank body is fixedly installed with a condensate outlet. The inner bottom of the tank body is fixedly installed with a mounting frame, a mounting rod is fixedly installed on the top of the mounting frame, a filter cylinder body is sleeved on the outer side of the mounting rod, and a filter material is inserted into the interior of the filter cylinder body, and the filter material is arranged in a ring state with respect to the center point of the filter cylinder body; for this condensate iron removal filtration device, by sleeving the filter cylinder body on the rod body of the mounting rod, and then the inner cavity of the mounting frame is arranged in a "cross" shape structure state, and the lower end of the filter cylinder body is also arranged in a "cross" shape structure state, so that the filter cylinder body is clamped in the inner cavity of the mounting frame, thereby making it more convenient and fast to replace it, and at the same time prolonging the service life and treatment capacity.

[0004] However, the above patent still has the following deficiencies: the up and down movement range of the cleaning scraper is limited, and it can only clean the middle section inner wall of the tank body, with poor practicability; in addition, when there are iron filings with a relatively large volume in the condensate, it is not convenient for the iron filings to enter the tank body to be processed by the filter cylinder body and the filter material, and it is also not convenient for the impurities filtered by the anti-blocking cylinder body in the condensate outlet to be discharged.
