As shown in fig. 1-5, the present embodiment provides a gas-solid separation filter, which comprises a support base 1 and a gas-solid separation filtering device 2 disposed on the support base 1, wherein the gas-solid separation filtering device 2 comprises a feeding bin 21, a gas-solid separator whose upper portion is communicated with an outlet of the feeding bin 21, and an air outlet pipe 23 communicated with the gas-solid separator through an air flow channel 24;

the gas-solid separator comprises a first screen 22a and a second screen 22b which are arranged oppositely, a rotating shaft 22c which is arranged between the first screen 22a and the second screen 22b and can rotate around the axis of the first screen 22a and the second screen 22b, a rotating drum 22d sleeved on the rotating shaft 22c, blades 22f which are rotatably connected with the rotating drum 22d through a rotating shaft 22e, and scraping plates 22g arranged on the blades 22f, and further comprises a driving device 22h (which can adopt a motor and the like) for driving the rotating shaft 22c to rotate, wherein the upper parts of the first screen 22a and the second screen 22b form an upper opening 22i communicated with an outlet of the feeding bin 21, and the lower parts of the first screen 22a and the second screen 22b form a discharging opening 22 j;

Specifically, as shown in fig. 2 to 3, 6 blades 22f and 6 scrapers 22g are provided, and the blades 22f are distributed on the drum 22d at equal intervals. The above arrangement ensures that a valve-like, fully enclosed space is formed between the feed opening 22j and the upper screens (the first screen 22a and the second screen 22 b), so that air can only pass through the screens and reach the outside through the outlet duct 23 (in this case, the air can reach the circulating fan), and an efficient separation effect is ensured.

In this example, the mesh openings of the first and

second screens

22a and 22b may be set according to the size of the impurity particles, so as to filter the impurities and allow only air to pass through.

In this example, the scraper 22g is detachably disposed at the end of the blade 22f away from the drum 22d, and the scraper 22g is made of rubber, so that abrasion to the screen can be reduced.

The working principle and the process are as follows: the air outlet pipe 23 is connected with the air inlet of the circulating fan to generate negative pressure at the upper part of the gas-solid separation filtering device 2, the feeding bin 21 (including simultaneously entering air and foreign particles) conveys the air and the foreign particles or materials to the inside of the gas-solid separator through a pipeline, the air and the foreign particles or the materials are dispersed on the blades 22f and between the

blades

22f and 22f, under the action of the driving device 22h, the rotating shaft 22c rotates to drive the rotating drum 22d to rotate, and further drive the blades 22f to rotate, so that the air and the foreign particles or the materials are driven to move downwards on the blades 22f or between the

blades

22f and 22f, the air flows through the air flow channel 24 at the position of the first screen 22a or the second screen 22b through meshes and is discharged from the air outlet pipe 23 to the circulating fan, and the foreign particles or the materials can be discharged from the non-pressure discharge port 22j at the lower part under the drive, convenient and fast, and separation efficiency is high, is suitable for effectively getting rid of large granule impurity.

In this embodiment, in order to conveniently and rapidly perform the above operations, the gas-solid separation filter device 2 is further provided with a detection port 25, wherein the detection port 25 at the upper side is further provided with an air spring, which facilitates the opening and closing of the detection port 25. Meanwhile, the whole shell is formed by sheet metal parts, so that the sheet metal parts of the corresponding parts can be detached during maintenance, and the device is very convenient.

The gas-solid separation filter in the embodiment can run under positive pressure or negative pressure, the configuration of the circulating fan is more flexible, and the circulating fan can be placed in the front and back positions of the gas-solid separation filter.
