The second guide block is composed of a triangular protrusion, and the protrusion thickness of the second guide block on the straight trough wall first gradually increases and then gradually decreases along the flow direction of the cotton pulp. The range in which the first guide protrusion 17 is set along the flow direction of the cotton pulp is larger than the range in which the second guide protrusion 18 is set along the flow direction of the cotton pulp, such as Figure 8 , 9 Through the guidance of the first guide block and the second guide block, the cotton pulp in the beating trough 10 flows evenly along the width direction of the beating trough 10, and the cotton pulp on the inside and outside enters the beating mechanism for beating at basically or nearly the same flow rate, thereby improving the uniformity of the beating process and the beating effect.

[0036] The above-mentioned scheme provided by the utility model can effectively defoam the foam generated by pulping, and can clean or concentrate the cotton pulp, thereby improving the uniformity and efficiency of pulping.

[0037] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
