Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum material processing equipment, in particular to a condensing recovery device for aluminum material processing oil gas recovery treatment. BACKGROUND

[0002] In the process of aluminum material processing, a large amount of waste gas containing oil gas will be generated. These oil gases not only pollute the environment, but also pose a certain safety hazard, and also waste resources. Therefore, it is of great significance to recover and treat the oil gas in aluminum material processing. Among the common methods for recovering and treating oil gas in aluminum material processing, the condensing recovery device is an important equipment. In the condensing recovery process, the oil gas entering the condensing recovery device needs to be filtered first to prevent solid impurities such as metal chips and dust in the oil gas from entering the internal components of the condensing recovery device. Once these impurities enter, they will cause wear and tear to the condensing tube, compressor and other equipment, reducing the service life of the equipment, and in severe cases, even causing equipment failure, affecting the normal operation of oil gas recovery work.

[0003] However, the existing filter screen needs to be cleaned in time after use, otherwise it will be blocked due to the accumulation of impurities, resulting in a significant decrease in filtering effect. However, due to the working environment of aluminum material processing, oil bodies are often attached to the filter screen. When a single brush is used for cleaning, not only is the cleaning effect poor, but also the oil stains are easily squeezed to the other side of the filter screen during the cleaning process, making it impossible to completely remove the impurities on the filter screen. In addition, the splashing of oil stains during the cleaning of the filter screen will also pollute the surrounding environment, further increasing the difficulty of cleaning and maintenance.

[0004] A condensing recovery device is disclosed in Chinese Patent No. 2024211308763, which relates to the technical field of condensing recovery and includes a recovery tank, an inlet pipe arranged at the top of the recovery tank, a connecting pipe arranged at the bottom of the recovery tank, and a filter assembly arranged at the bottom of the connecting pipe. The filter assembly includes a guide pipe mounted on the bottom of the connecting pipe and a collection unit arranged outside the guide pipe. The connecting pipe has a filter screen installed on the inner wall thereof through a mounting unit. The mounting unit includes a mounting seat mounted on the front side of the connecting pipe, a mounting plate arranged inside the mounting seat, and a positioning part arranged on the side of the mounting plate. The mounting plate is mounted on one side of the filter screen, and the positioning part includes a receiving groove arranged inside the side wall of the mounting seat, one end of an extrusion piece mounted on the side wall of the receiving groove, and one end of a positioning column fixedly connected with the other end of the extrusion piece.

[0005] For the related technology in the above, the inventors found that the following defects exist: the above patent only provides a convenient dismounting structure for the filter screen. CONTENT OF THE UTILITY MODEL

When the brushes on both sides of the filter screen move by relying on the sliding pipes, the filter screen will be cleaned.

[0008] Optionally, a rectangular hole is arranged on the air inlet pipe close to the two through holes, a sealing plug is detachably arranged on the rectangular hole, and a placing box is arranged on the air inlet pipe at the position of the rectangular hole. A shielding cloth that can extend into the air inlet pipe is arranged in the placing box.

[0009] Optionally, a winding disc is arranged in the placing box, the shielding cloth is wound on the winding disc, an opening for the shielding cloth to move out is arranged on the placing box, and a detachable counterweight is arranged on one end of the shielding cloth away from the winding disc. When the counterweight is connected to the shielding cloth, the shielding cloth will automatically move downward into the air inlet pipe to shield the splashed oil stains generated when the brush is working.

[0010] Optionally, a through hole is arranged on the air inlet pipe, the through hole and the through hole are symmetrically arranged about the center line of the air inlet pipe, and detachable receiving boxes are arranged on the air inlet pipe at the positions of the through holes. Sealing rings are arranged between the two receiving boxes and the air inlet pipe.

[0011] Optionally, a sliding groove is arranged on the limiting plate, a sliding block that cooperates with the sliding groove is arranged on one end of the sliding pipe, an empty groove is arranged on one end of the frame body close to the sliding pipe, a tension spring connected to the sliding pipe is arranged in the empty groove, and when the sliding pipe moves to the position of the through hole, the extension of the tension spring will move the brush out of the air inlet pipe and facilitate replacement when the frame body is continuously pulled.

[0015] 3. By arranging a tension spring between the frame body and the sliding pipe, when the sliding pipe moves to the through hole position, continuing to pull the frame body can move the brush out of the air inlet pipe, facilitating the replacement of the brush which is severely worn or dirty;

[0016] 4. The through hole and the detachable receiving box arranged on the air inlet pipe can collect the impurities and oil falling during the cleaning of the filter screen, and the sealing ring arranged between the receiving box and the air inlet pipe ensures the sealing property, prevents the leakage of impurities and oil, and facilitates the subsequent centralized treatment.
