[0034] Embodiment 1:
[0035] Please refer to Figure 1 - Figure 6 , a novel flow guide shell, which includes:
[0036] The flow guide shell main body includes a housing 1, end plates 2 are arranged at both ends of the housing 1, a plurality of reinforcing members 5 are fixedly connected between the outer side of the housing 1 and the end plates 2, a central member 3 is arranged inside the housing 1, a plurality of flow guide plates 4 are arranged on the periphery of the central member 3, one ends of the plurality of flow guide plates 4 are fixedly connected to the central member 3, and the other ends of the plurality of flow guide plates 4 are fixedly connected to the inner wall of the housing 1; further, the material of the flow guide shell main body is any one of cast iron, cast copper, nylon plastic, and stainless steel.
