Description

Technical Field

[0001] This invention relates to the field of papermaking technology, and in particular to an internal material guiding and temperature regulating device for centrifuges. Background Technology

[0002] The papermaking industry is an important part of industrial production, and pulp treatment, as a key step in papermaking, directly affects pulp quality and production efficiency. During pulp treatment, centrifuges are used to separate the pulp.

[0003] Traditional centrifuges have a simple structure and single function, simply centrifuging raw materials without controlling the temperature of the raw materials during centrifugation. Furthermore, they cannot quickly transport and guide the materials after production, resulting in low work efficiency. The high-temperature resistance and safety of the equipment are also very limited. Summary of the Invention

[0004] The technical problem to be solved by this invention is that traditional centrifuges have simple structures and single functions. After production is completed, they cannot quickly transport and guide materials, resulting in low work efficiency. The high temperature resistance and safety of the equipment are also very limited.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an internal material guiding and temperature regulating device for centrifuges, including a vertical main frame, four centrifugal shafts movably mounted on the side wall of the vertical main frame, a lateral baffle cover opened on the outer side of the vertical main frame, a bottom material guiding mechanism movably mounted inside the lateral baffle cover below the centrifugal shafts, a rear liquid storage tank with a booster water pump installed inside the back of the vertical main frame, a spiral heat exchange tube that cooperates with the liquid outlet of the booster water pump fixedly mounted inside the centrifugal shafts, and an embedded guide tube fixedly mounted on the inner wall of the lateral baffle cover.

[0006] An outer hydraulic strut for controlling the lateral baffle is fixedly mounted on the outer side of the vertical main frame. The extended end of the outer hydraulic strut is fixedly connected to the outer side of the lateral baffle through a lateral bracket.

[0007] The lateral baffle includes a vertical protective cover that is slidably sleeved on the outside of the vertical main frame and a horizontal guide cover that is fixed to the lower end of the outside of the vertical protective cover.

[0008] An inwardly protruding inner guide shield is fixedly installed on the inner side of the rear liquid storage tank.

[0009] The inner arc-shaped surface of the inner guide shroud is provided with an annular guide groove that matches the outer return port of the spiral heat exchange tube. The center of the vertical surface of the inner guide shroud has a conical guide nozzle that protrudes towards the outer inlet of the spiral heat exchange tube.

[0010] The outer arc-shaped surface of the centrifugal shaft has an integrated pressure booster blade corresponding to the position of the annular guide groove.

[0011] The vertical main frame has horizontally placed strip-shaped guide grooves on both outer walls, and the inner side of the side baffle has built-in guide blocks that protrude into the horizontally placed strip-shaped guide grooves.

[0012] An elastic check valve is installed inside the built-in guide block.

[0013] The embedded guide tube includes a first embedded guide tube fixed on the inner side of the vertical protective cover and a second embedded guide tube fixed on the inner side of the horizontal material guide cover.

[0014] An external guide pipe for connecting the built-in guide block and the water outlet pipe of the booster pump is fixedly installed on the outer side of the side baffle.

[0015] The beneficial effects of this invention are:

[0016] (1) The internal material guiding and temperature regulating device for centrifuge of the present invention can greatly improve the safety and heat insulation during centrifugation by setting a side baffle around the centrifuge shaft cylinder;

[0017] (2) A bottom-mounted material guiding mechanism is movably installed inside the side baffle below the centrifugal shaft, which can guide the solid material after formation laterally and improve the material guiding efficiency of the equipment.

[0018] (3) A rear storage tank with an internal booster water pump is fixedly installed on the back of the vertical main frame. The booster water pump introduces the internal heat exchange liquid into the spiral heat exchange tube inside the centrifugal cylinder and the embedded guide tube inside the side baffle, which can regulate the temperature and improve the stability and durability of the equipment while ensuring processing efficiency.

[0019] (4) The side baffle uses a horizontal adjustment method to guide the material, which can quickly separate the products and avoid mutual interference;

[0020] (5) The entire equipment's production and material conveying are carried out inside the same chamber, free from external environmental interference;

[0021] (6) The driving efficiency of the internal fluid can be rapidly improved by the influence of the centrifugal shaft rotation speed, thus ensuring the heat exchange effect;

[0022] (7) By changing the position of the side baffle, it can be adapted to different operating methods and processing methods, and has a wider range of applications;

[0023] (8) By placing the flow outlet directly inside the rear liquid storage tank, the impact of leakage on the equipment can be avoided. Attached Figure Description

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

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The centrifuge internal material guiding and temperature regulating device shown includes 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 baffle 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 baffle 3 below the centrifugal shaft cylinders 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 that cooperates with the liquid outlet of the booster water pump 5 is fixedly mounted inside the centrifugal shaft cylinders 2, and an embedded guide tube 8 is fixedly mounted on the inner wall of the lateral baffle 3.

[0033] Working principle: By adjusting the horizontal position of the side baffle 3, the high-temperature raw material is introduced into the centrifugal cylinder 2 from the upper opening. Then, the centrifugal cylinder 2 separates the solid matter in the mixed pulp through the centrifugal action generated by high-speed rotation. The solid matter is then guided to the left from the bottom guide mechanism 4. During centrifugation and material guidance, the booster water pump 5 introduces the heat exchange liquid in the rear storage tank 6 into the spiral heat exchange tube 7 inside the centrifugal cylinder 2. It is first introduced from the middle to the front end of the centrifugal cylinder 2. Then, the centrifugal cylinder 2 is guided outward by the centrifugal action generated by high-speed rotation, which controls the temperature of the centrifugal cylinder 2. The heat exchange liquid then flows back into the rear storage tank 6 through the spiral heat exchange tube 7. When the temperature inside the side baffle 3 becomes too high, the booster water pump 5 introduces the heat exchange liquid in the rear storage tank 6 into the embedded guide tube 8 to cool the solid matter.

[0034] To facilitate lateral adjustment and translation, an outer hydraulic support rod 9 for controlling the lateral baffle 3 is fixedly mounted on the outer side of the vertical main frame 1. The extended end of the outer hydraulic support rod 9 is fixedly connected to the outer side of the lateral baffle 3 through a lateral bracket.

[0035] To facilitate lateral protection, the lateral baffle 3 includes a vertical protective cover 31 that is slidably sleeved on the outside of the vertical main frame 1 and a horizontal guide cover 32 that is fixed to the lower outside of the vertical protective cover 31.

[0036] The bottom guiding mechanism 4 consists of a horizontal drive shaft movably installed inside the horizontal guiding cover 32 and a spiral guiding blade fixed to the outside of the horizontal drive shaft. A circular transmission blind hole that mates with the spiral guiding blade is provided on the side wall of the vertical main frame 1. The outer end of the horizontal drive shaft is movably assembled with the inner wall of the outer side of the horizontal guiding cover 32. A guide drive shaft is assembled on the inner wall of the circular transmission blind hole. The horizontal drive shaft is assembled and supported by being sleeved on the guide drive shaft. When the side baffle 3 is adjusted horizontally, it can ensure bottom guiding while facilitating adjustment.

[0037] To facilitate internal assembly, an inwardly protruding inner guide shield 61 is fixedly mounted on the inner side of the rear liquid storage tank 6.

[0038] In order to facilitate internal flow guidance, an annular flow guide groove 62 is provided on the inner arc surface of the inner flow guide shroud 61 to cooperate with the outer return port of the spiral heat exchange tube 7, and a conical flow guide nozzle 63 protruding towards the outer inlet of the spiral heat exchange tube 7 is located at the center of the inner vertical surface of the inner flow guide shroud 61.

[0039] The booster pump 5 operates, and then the booster pump 5 guides the heat exchange liquid inside the rear storage tank 6 into the conical guide nozzle 63, and then through the conical guide nozzle 63 into the spiral heat exchange tube 7, and then through the spiral heat exchange tube 7 back into the annular guide groove 62, and then according to the electric control valve fixed on the side wall of the inner guide shroud 61, it can be selected to return to the rear storage tank 6 or the embedded guide tube 8.

[0040] To improve reflux efficiency, the outer arc-shaped surface of the centrifugal shaft cylinder 2 has an integrated pressure boosting blade 10 at the position corresponding to the annular guide groove 62.

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

[0042] In order to cooperate with the side guides and improve the adjustment stability of the side baffle 3, the outer walls of both sides of the vertical main frame 1 are provided with horizontal strip guide grooves 11, and the inner side of the side baffle 3 has built-in guide blocks 12 that protrude into the horizontal strip guide grooves 11.

[0043] To facilitate control, a resilient check valve 13 is installed inside the built-in guide block 12. The resilient check valve 13 can be modified to an electrically controlled design, allowing for flow guidance as needed.

[0044] To facilitate internal heat exchange, the embedded guide tube 8 includes a first embedded guide tube 81 fixed on the inner side of the vertical protective cover 31 and a second embedded guide tube 82 fixed on the inner side of the horizontal material guide cover 32.

[0045] The side baffle 3 can be adjusted by translation to fit centrifugal shaft cylinders 2 with different protrusion lengths. A circular through hole that matches the centrifugal shaft cylinder 2 is opened on the outer side of the side baffle 3, and a detachable closing cover is installed on the outer opening of the circular through hole. Moreover, the vertical protective cover 31 can be translated outward to increase the gap between the front end of the centrifugal shaft cylinder 2 and the inner wall of the side baffle 3, which facilitates heat dissipation at the front end.

[0046] In order to facilitate external flow, an external flow guide pipe 14 for connecting the built-in guide block 12 and the outlet pipe of the booster water pump 5 is fixedly installed on the outer side of the side baffle 3.

[0047] The booster pump 5 draws the heat exchange fluid from the rear storage tank 6 into the external guide pipe 14, and then guides it into the embedded guide pipe 8 through the external guide pipe 14. When the side baffle 3 moves outward, the elastic check valve 13 inside the built-in guide block 12 is squeezed against the inner wall of the left side 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 guide pipe 82 through the built-in guide block 12. The second embedded guide pipe 82 then performs heat exchange and cooling on the inner surface of the horizontal guide cover 32. When the side baffle 3 moves inward, the elastic check valve 13 inside the built-in guide block 12 is squeezed against the inner wall of the right side 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 guide pipe 81 through the built-in guide block 12. The first embedded guide pipe 81 then performs heat exchange and cooling on the inner surface of the vertical protective cover 31.

[0048] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
