[0013] EMBODIMENT

[0014] Figure 2 The pull-bag type centrifuge shown in FIG. 1 includes a cover 10, a pull-bag support 20 and a feeding pipe 30. The pull-bag support 20 is located in an inner container part 40, the feeding pipe 30 is fixed in the cover 10, the inner side of the cover 10 is provided with a cover shell 50 extending downward and sleeving outside the pull-bag support, the outer side of the pull-bag support 20 is fixed with a cloth cover 60 located below the cover shell 50, a passage one 70 is formed between the inner wall of the cover shell 50 and the outer wall of the pull-bag support 20, a passage two 80 is formed between the inner wall of the cloth cover 60 and the outer wall of the pull-bag support 20, the bottom of the cover shell is inserted into the cloth cover, and the passage one and the passage two are communicated. A feeding pipe 90 is provided on the side wall of the cover shell 50 and communicated with the passage one, and the bottom end of the feeding pipe 30 is inserted into the feeding pipe 90. A guide part 100 protruding outward is provided on the side of the cloth cover 60, and a discharging groove 101 communicated with the passage two is provided in the guide part 100. The feeding pipe 30 feeds the material into the passage one 70, the material enters the passage two 80 under the action of gravity, and the cloth cover 60 rotates at high speed together with the pull-bag support and the inner container part, so that the material in the passage two is evenly thrown out from the discharging groove, thus improving the dehydration effect of the centrifuge. Moreover, the material remaining in the feeding pipe directly enters the passage one, and thus does not directly drop into the cloth bag, so that the material already treated in the cloth bag is not polluted.

[0015] Preferably, the feeding pipe 90 is upwardly inclined, and the included angle between the central axis of the feeding pipe and the horizontal line is 20°-30°. The material slides into the passage one 70 along the feeding pipe, thus effectively avoiding the blockage of the material at the outlet of the feeding pipe.

[0016] Preferably, the top of the cloth cover 60 is provided with a ring of baffle 67 extending upwardly and inclined away from the side of the bag holder, which increases the overlapping height of the top of the cloth cover 60 and the bottom of the cover shell 50, effectively preventing the material from overflowing from the top of the cloth cover. The baffle 67 is arranged in an inclined flared shape, so that when the machine cover is rotated open, the cover shell 50 is rotated open upwardly together with the machine cover, and the baffle 67 does not interfere with the cover shell 50.

[0017] As a further improvement of the embodiment, the cloth cover 60 comprises an upper pipe 61 and a lower pipe 62, the baffle is arranged at the top of the upper pipe 61, the upper pipe is sleeved outside the lower pipe, the bottom of the upper pipe is provided with a ring of skirt 63, the sidewall of the lower pipe 62 is provided with a ring of skirt 64 below the skirt 63, the skirt 63 and the skirt 64 together form a guide part 100, and the lower sidewall of the skirt 63 and the upper sidewall of the skirt 64 form a discharge slot 101. Preferably, the lower pipe 62 is fixed to the outer wall of the bag holder 20, the skirt 63 and the skirt 64 are fixedly connected through a plurality of annularly arranged bolts 65, and the width of the discharge slot can be adjusted by adjusting the number of nuts between the two skirts on the bolts.

[0018] Preferably, the skirt 63 and the skirt 64 are inclined downwardly relative to one end of the bag holder, the included angle between the skirt 63 and the central vertical axis of the bag holder is 10°-15° smaller than the included angle between the skirt 64 and the central vertical axis of the bag holder, so that the outlet end of the discharge slot 101 is narrower than the inlet end, which increases the speed of the material flying out of the discharge slot. In the embodiment, the included angle H1 between the skirt 63 and the central vertical axis of the bag holder is 50°, and the included angle between the skirt 64 and the central vertical axis of the bag holder is 65°.

[0019] Preferably, the lower pipe 62 is composed of two semicircular plate members 621, which are welded to the top of the skirt 64, and each end of the semicircular plate member is provided with an ear plate 66, the lower pipe 62 is sleeved outside the bag holder 20, and the bolts in the two opposite ear plates are tightened to fix the lower pipe to the outer wall of the bag holder.

[0020] Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Accordingly, the application is not to be restricted based on the specific embodiments illustrated herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
