[0006] Preferably, the blowing pipe is connected to a compressed air supply pipe, and a manual ball valve, a solenoid valve and a check valve are sequentially provided on the compressed air supply pipe.

[0007] Preferably, the upper end of the protective cover is open and provided with a connecting flange, and a blind flange is provided on the connecting flange through a plurality of bolt pairs.

[0008] Preferably, a filter is provided on each of the exhaust holes.

[0009] Preferably, the protective cover is arranged on the pulping tank, and a plurality of cleaning holes are arranged on the pulping tank between the protective cover and the filter bag, and the cleaning holes are all provided with plugs.

[0010] Beneficial effects of the utility model: the utility model captures fly ash generated by slaked lime or quicklime entering the pulping tank in large quantities through filter bags. Compared with the prior art, the utility model has simple equipment, simple operation, small investment and small land occupation.

[0011] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.
