Based on the embodiment in the utility model, all other embodiments obtained by those skilled in the art without making creative labor are within the protection scope of the utility model.

[0011] The utility model is further illustrated below in combination with the drawings and preferred embodiments.

[0012] Embodiment 1

[0013] Referring to Figure 1 The utility model relates to a kind of cloth bag dust collector bypass valves with additional cleaning device, including clean gas chamber 100 and flue gas chamber 200, flue gas chamber 200 is opened with the side mouth 1 of making both communication, the clean gas chamber 100 is fixed with cylinder 2 outside, the telescopic rod of cylinder 2 is connected with the bypass valve stem 3 that enters the clean gas chamber, the end of bypass valve stem 3 is equipped with the bypass valve plate 4 that opens and closes the side mouth, bypass valve stem 3 is equipped with hollow shaft motor 5, hollow shaft motor 5 is connected with the clean gas chamber 100, the output shaft of hollow shaft motor 5 is driven connection with the rotary scraper 6 that is sleeved on bypass valve stem, rotary scraper 6 has scraper head 7 that is attached to the wall of bypass valve stem 3, scraper head 7 is diamond cutter head.

[0014] In the present embodiment, the bypass valve stem 3 is axially moved by being sleeved with a hollow shaft motor 5 fixed with the clean gas chamber 100, the bypass valve stem 3 axially moved penetrates the hollow shaft of the hollow shaft motor 5 and still can be axially moved. By rotating the shaft driven by the motor, the rotary scraper 6 and the scraper head 7 thereon are also driven to rotate through transmission, cooperating with the axially moved bypass valve stem 3, the bypass valve stem 3 wall surface remaining crystals can be quickly and thoroughly cleaned.

[0015] Wherein, the scraper body is made of stainless steel, and diamond is attached to the scraper head to enhance its strength and increase its corrosion resistance.
