They simply centrifuge the raw materials and are unable to control the temperature of the raw materials during the centrifugal action. Moreover, they are unable to quickly transport and separate the materials after production is completed, resulting in low work efficiency. The high temperature resistance and safety of the equipment are also very limited. Summary of the invention

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An internal material guiding and temperature regulating device for a centrifuge is shown, comprising a vertical main frame 1, four centrifugal shaft cylinders 2 are movably mounted on the side wall of the vertical main frame 1, a lateral material blocking cover 3 is provided on the outer side of the vertical main frame 1, a bottom material guiding mechanism 4 is movably mounted inside the lateral material blocking cover 3 and located below the centrifugal shaft cylinder 2, a rear liquid storage tank 6 with a booster water pump 5 installed inside is fixedly mounted on the back of the vertical main frame 1, a spiral heat exchange tube 7 matched with the liquid outlet of the booster water pump 5 is fixedly mounted inside the centrifugal shaft cylinder 2, and an embedded flow guide pipe 8 is fixedly mounted on the inner wall of the lateral material blocking cover 3.

[0033] Working principle: by adjusting the horizontal position of the lateral material blocking cover 3 horizontally, the high-temperature raw material is introduced into the centrifugal shaft cylinder 2 from the upper opening at this time, and then the centrifugal shaft cylinder 2 is separated from the mixed pulp by the centrifugal effect generated by the high-speed rotation, and then the solid matter is guided to the left from the bottom-mounted guide mechanism 4 at the bottom. While centrifuging and guiding, the booster water pump 5 guides the heat exchange fluid in the rear liquid storage tank 6 into the spiral heat exchange tube 7 inside the centrifugal shaft cylinder 2, first from the middle to the front end of the centrifugal shaft cylinder 2, and then the centrifugal shaft cylinder 2 is guided outward by the centrifugal effect generated by the high-speed rotation to control the temperature of the centrifugal shaft cylinder 2, and then the heat exchange fluid flows back to the rear liquid storage tank 6 through the spiral heat exchange tube 7; when the temperature inside the lateral material blocking cover 3 is too high, the booster water pump 5 guides the heat exchange fluid in the rear liquid storage tank 6 into the embedded guide tube 8 to cool the generated solid matter.

[0034] In order to cooperate with the lateral adjustment translation, an outer hydraulic support rod 9 for controlling the lateral material blocking cover 3 is fixedly installed on the outer side of the vertical main frame 1, and the extended end of the outer hydraulic support rod 9 is fixedly connected to the outer side of the lateral material blocking cover 3 through a lateral bracket.

[0035] In order to cooperate with the lateral protection, the lateral material blocking cover 3 includes a vertical protection cover shell 31 slidably sleeved on the outside of the vertical main frame 1 and a horizontal material guiding cover shell 32 fixed on the lower end of the outer side of the vertical protection cover shell 31 .

[0036] The bottom material guiding mechanism 4 consists of a transverse driving shaft movably installed inside the horizontal material guiding cover shell 32 and a spiral material guiding blade fixed on the outside of the transverse driving shaft. A circular transmission blind hole matching the spiral material guiding blade is opened on the side wall of the vertical main frame 1. The outer end of the transverse driving shaft is movably assembled with the outer inner wall of the horizontal material guiding cover shell 32. A guide driving shaft is mounted on the inner wall of the circular transmission blind hole. The transverse driving shaft is assembled and supported by being sleeved on the guide driving shaft. When the lateral material blocking cover 3 is adjusted horizontally, the bottom material guiding can be ensured and the adjustment is convenient at the same time.

[0037] In order to facilitate internal assembly, an inner side guide cover 61 protruding inwardly is fixedly mounted on the inner side surface of the rear liquid storage tank 6 .

[0038] In order to cooperate with the internal flow diversion, an annular flow guide groove 62 that matches the outer return port of the spiral heat exchange tube 7 is opened on the inner curved surface of the inner flow guide cover 61, and a conical flow guide nozzle 63 protruding toward the outer inlet of the spiral heat exchange tube 7 is provided at the center of the inner vertical surface of the inner flow guide cover 61.

[0039] The booster water pump 5 is running, and then the booster water pump 5 introduces the heat exchange liquid inside the rear liquid storage tank 6 into the conical guide nozzle 63, and then introduces it into the spiral heat exchange tube 7 through the conical guide nozzle 63, and then returns to the annular guide groove 62 through the spiral heat exchange tube 7, and then selects to return to the rear liquid storage tank 6 or the embedded guide tube 8 according to the electric control valve fixed on the side wall of the inner guide cover 61.

[0040] In order to improve the reflux efficiency, the outer arc surface of the centrifugal shaft cylinder 2 has a booster blade 10 of an integrated structure at a position corresponding to the annular guide groove 62 .

[0041] When there is more accumulated liquid inside the annular guide groove 62, the boost blade 10 will come into contact with the accumulated liquid. Sometimes the boost blade 10 will produce a centrifugal boosting effect on the accumulated liquid, thereby accelerating the accumulated liquid to flow back to the rear liquid storage tank 6 or the embedded guide pipe 8, and then flow back to the rear liquid storage tank 6 through the embedded guide pipe 8.

[0042] In order to cooperate with the guide on both sides and improve the adjustment stability of the lateral material blocking cover 3, transverse strip guide grooves 11 are opened on the outer walls on both sides of the vertical main frame 1, and the inner side of the lateral material blocking cover 3 has a built-in guide block 12 protruding into the transverse strip guide groove 11.

[0043] In order to cooperate with the control, an elastic check valve 13 is installed inside the built-in guide block 12. The elastic check valve 13 can be changed into an electronically controlled structure design, and flow guidance can be performed as needed.

[0044] In order to cooperate with internal heat exchange, the embedded guide pipe 8 includes a first embedded guide pipe 81 fixed on the inner side of the vertical protective cover shell 31 and a second embedded guide pipe 82 fixed on the inner side of the horizontal material guide cover shell 32 .

[0045] The lateral blocking cover 3 can be adjusted by translation to adapt to the centrifugal shaft barrel 2 with different protruding lengths, and then a circular through hole matching the centrifugal shaft barrel 2 is opened on the outer surface of the lateral blocking cover 3, and a detachable closed cover is installed on the outer opening of the circular through hole. Moreover, the vertical protective cover shell 31 can translate outward to increase the gap between the front end of the centrifugal shaft barrel 2 and the inner wall of the lateral blocking cover 3, so that the heat dissipation of the front end can be facilitated.

[0046] In order to cooperate with the external flow diversion, an external flow diversion pipe 14 for connecting the built-in guide block 12 and the water outlet pipe of the booster water pump 5 is fixedly mounted on the outer side surface of the lateral material blocking cover 3.

[0047] The booster water pump 5 draws the heat exchange fluid in the rear liquid storage tank 6 into the external guide pipe 14, and then introduces it into the embedded guide pipe 8 through the external guide pipe 14. When the lateral material blocking cover 3 is translated outward, the elastic check valve 13 in the built-in guide block 12 is squeezed to the left inner wall of the horizontal strip guide groove 11. At this time, the heat exchange fluid in the external guide pipe 14 flows into the second embedded conduit 82 through the built-in guide block 12. At this time, the second embedded conduit 82 performs heat exchange and cooling on the inner surface of the horizontal material guiding cover shell 32; and when the lateral material blocking cover 3 is translated inward, the elastic check valve 13 in the built-in guide block 12 is squeezed to the right inner wall of the horizontal strip guide groove 11. At this time, the heat exchange fluid in the external guide pipe 14 flows into the first embedded conduit 81 through the built-in guide block 12. At this time, the first embedded conduit 81 performs heat exchange and cooling on the inner surface of the vertical protective cover shell 31.
