Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to an anti-blocking centrifuge. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate liquid from solid particles or components in a mixture of liquid and liquid. Its working principle is based on two methods: centrifugal filtration and centrifugal sedimentation. Centrifugal filtration is to use the centrifugal pressure generated by the suspension in the centrifugal field to act on the filter medium, so that the liquid passes through the filter medium to become filtrate, while the solid is trapped on the surface of the filter medium to achieve solid-liquid separation.

[0003] In practical applications, centrifuges sometimes need to centrifuge flocculent / filamentary solid-liquid mixtures. According to application feedback, we know that, in general, short-filament floccules are in a clumping state after dehydration, so it is difficult for them to block the casing. However, some long-filament floccules are easy to stick to the inside of the casing during slag discharge. The more difficult-to-discharge materials accumulate, the more likely they are to block the discharge cavity. Therefore, how to solve this problem from the source has become the direction and purpose we urgently need to discuss. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0018] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Figure 1-Figure 3 The schematic diagram of the whole structure of the utility model is shown. Figure 1-Figure 3 A blocking-proof centrifuge according to the present embodiment includes a centrifuge body 100, a splitting feed barrel 200 is arranged at the feed end of the centrifuge body 100, a discharge port 210 directly connected to the feed end of the centrifuge body 100 is arranged at the bottom of the splitting feed barrel 200, a feed port 220 is arranged on one side of the top of the splitting feed barrel 200, a rotating rod 300 is vertically rotatably installed at the axial center of the inner part of the splitting feed barrel 200, a multi-layer straight-edge blade 310 is arranged on the outer peripheral side of the rotating rod 300 and along its height direction, a rotating driving assembly 400 that can drive the rotating rod 300 to rotate is also arranged at the upper end of the splitting feed barrel 200, a high-pressure injection pipe 500 connected to a high-pressure gas source is also arranged around the inner top edge of the splitting feed barrel 200, and a plurality of gas nozzles 510 are also arranged around the bottom of the high-pressure injection pipe 500.

[0021] The rotary drive assembly 400 includes a first pulley 410 fixed to the upper end of the rotating rod 300, a rotating shaft 420 vertically rotating and secured to the upper part of the segmentation feed cylinder 200, a second pulley 430 fixed to the outside and parallel to the first pulley 410, a belt 440 connected to the first pulley 410 at one end and to the second pulley 430 at the other end, a motor 450 whose output shaft is connected to the end of the rotating shaft 420, and a bearing 460 mounted on the top of the segmentation feed cylinder 200 and rotatably mounted on the rotating rod 300 and the rotating shaft 420, respectively. A feed hopper 221 fixed to the segmentation feed cylinder 200 is also provided on the upper peripheral side of the feed port 220. It can be understood that by providing the feed hopper 221 The material can be more conveniently introduced into the feed port 220 and the dividing feed barrel 200. When in use, the motor 450 drives the rotating shaft 420 and the second pulley 430 to rotate, and then the belt 440 drives the first pulley 410 and the straight-edged blade 310 to rotate rapidly. At the same time, the solid-liquid mixture introduced into the dividing feed barrel 200 from the feed port 220 will directly contact the straight-edged blade 310, and the high-speed rotating straight-edged blade 310 will quickly divide and cut the filamentary flocculent fibers in the material. Then, under the action of gravity, the material will directly enter the centrifuge drum through the discharge port 210, effectively avoiding the disadvantage that the material is easy to stick to the inside of the cover shell and cause blockage to the discharge cavity during slag discharge.

[0022] A connecting nozzle valve 520 connected to the high-pressure jet pipe 500 is also provided on the outside of the cutting and conveying barrel 200, and the connecting nozzle valve 520 is connected to the high-pressure gas source through an external pipeline. When the material is rotary cut and divided, it is inevitable that some materials will be thrown out and temporarily adhere to the inner wall of the cutting and conveying barrel 200, thereby hindering the normal operation of the blade. Therefore, during the cutting process, the high-pressure jet pipe 500 can push the material that may adhere to the inner wall of the conveying barrel through the air nozzle 510 under the infusion of the high-pressure gas source, so that the logistics slides down quickly, avoiding material blockage in the cutting and conveying barrel 200, and further improving the cutting and material guiding efficiency.

[0023] Furthermore, the outer side of the bottom of the dividing feed barrel 200 also has a connecting flange 230 that fits on the peripheral side of the feed end of the centrifuge body 100, and bolts 240 for locking the connecting flange 230 and the centrifuge body 100. It can be understood that the dividing feed barrel 200 forms a detachable structure with the centrifuge body through the connection and cooperation of the connecting flange 230 and the bolts 240, which is more convenient to use and maintain.

[0024] Furthermore, a hood 600 is provided on the top of the outer side of the split feed barrel 200 and is covered on the outer side of the rotating drive assembly 400. A controller 610 connected to the motor 450 and the high-pressure gas source control end signal is also provided on the upper part of the hood 600. Here, the controller 610 can facilitate the staff to uniformly control the motor 450 and the high-pressure gas source, which is more convenient to use.

[0025] In summary, in the present embodiment, a blocking-proof centrifuge is used to introduce materials into the feed port 220 and the dividing feed cylinder 200 through the feed hopper 221, and the rotating shaft 420 and the second pulley 430 are driven to rotate by the motor 450, and then the first pulley 410 and the straight-edged blade 310 are driven to rotate rapidly by the belt 440. At the same time, the solid-liquid mixture introduced into the dividing feed cylinder 200 from the feed port 220 will directly contact the straight-edged blade 310, and the high-speed rotating straight-edged blade 310 will quickly divide and cut the filamentary flocculent fibers in the material, and then the material will directly enter the centrifuge drum through the discharge port 210 under the action of gravity, effectively avoiding the disadvantage that the material is easy to stick to the inside of the cover during slag discharge.

[0026] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
