Description

Technical Field

[0001] This utility model relates to the technical field of double cone rotary vacuum dryers, and in particular to a double cone rotary vacuum dryer. Background Technology

[0002] A rotary vacuum dryer is a drying device that uses a double cone to rotate and heat the air. Before the double cone rotates, the air inside the double cone needs to be extracted, which facilitates the escape of water vapor and improves drying efficiency.

[0003] In the existing technology, during the rotation of the double cone, the agglomerated raw material inside is not easy to break, and the water vapor inside the agglomerated raw material is not easy to escape, thus delaying the drying efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a double-cone rotary vacuum dryer.

[0005] A double-cone rotary vacuum dryer includes a double cone, the top and bottom of which are hollow. A clamping cavity is formed inside the double cone. A rotating steam inlet pipe is connected to the input end of the clamping cavity, and a rotating steam outlet pipe is connected to the output end of the clamping cavity. A fixed steam inlet pipe is rotatably installed at the input end of the rotating steam inlet pipe, and a fixed steam outlet pipe is rotatably installed at the output end of the rotating steam outlet pipe. An exhaust port aligned with the rotating steam outlet pipe is formed in the middle of the inner cavity of the double cone. An inwardly protruding interceptor mesh aligned with the exhaust port is welded to the inner wall of the double cone. The interceptor mesh has a porous structure. A rotating exhaust pipe protruding outward and aligned with the exhaust port is integrally formed on the inner wall of the double cone. A fixed exhaust pipe is rotatably installed at the output end of the rotating exhaust pipe. An impact mechanism is fixedly installed inside the double cone.

[0006] By adopting the above technical solution, it is possible to assist in the crushing of agglomerated raw materials during the heating process.

[0007] The impact mechanism includes a fixed ring fixedly installed on the inner wall of the rotating steam inlet pipe. The fixed ring has a porous structure, and a connecting shaft is fixedly installed at the center of the fixed ring. The end of the connecting shaft away from the fixed ring is fixedly connected to the center of one end of the interception net. An impact disk is interference-fitted onto the outer wall of the connecting shaft.

[0008] By adopting the above technical solution, the raw material that is swaying up and down will come into full contact with the collision disc, thus achieving an auxiliary crushing effect.

[0009] A rotating cover plate is rotatably installed on the top of the feed inlet of the double cone cylinder. A support lug is welded to the bottom of the feed inlet of the double cone cylinder. A locking bolt is rotatably installed on the inner side of the support lug. A locking nut is threaded onto the outer wall of the locking bolt. A sealing ring is installed at the contact position between the rotating cover plate and the feed inlet of the double cone cylinder.

[0010] By adopting the above technical solution, the rotating cover can be easily opened and closed.

[0011] A pressure gauge is installed at the center of the top of the rotating cover plate, penetrating into the inner cavity of the double cone cylinder, with the sensing end of the pressure gauge located in the inner cavity of the double cone cylinder.

[0012] By adopting the above technical solution, when the gas is pumped out after the raw materials are added, the pressure inside the double cone can be observed by a pressure gauge to see if it meets the standard.

[0013] The output end of the fixed exhaust pipe is connected to the air pump, and a valve is installed on the fixed exhaust pipe.

[0014] By adopting the above technical solution, when the device is not running, the valve is closed to prevent external impurities from entering the double cone through the fixed exhaust pipe and the rotating exhaust pipe.

[0015] The beneficial effects of the plow-type unloader with a cleaning mechanism of this utility model are:

[0016] By setting up a collision mechanism, the material can fully contact the collision mechanism as it oscillates with the double cone, thereby assisting in the rapid crushing of agglomerated raw materials and preventing the problem of water vapor inside the agglomerated raw materials from not easily escaping.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0022] Reference Figure 1-3 A double-cone rotary vacuum dryer includes a double cone cylinder 1, the top and bottom of which are hollow. A clamping cavity 6 is formed inside the double cone cylinder 1. A rotating steam inlet pipe 7 is connected to the input end of the clamping cavity 6, and a rotating steam outlet pipe 8 is connected to the output end of the clamping cavity 6. A fixed steam inlet pipe 9 is rotatably installed at the input end of the rotating steam inlet pipe 7, and a fixed steam outlet pipe 10 is rotatably installed at the output end of the rotating steam outlet pipe 8. An exhaust port 16, aligned with the rotating steam outlet pipe 8, is formed in the middle of the inner cavity of the double cone cylinder 1. An inwardly protruding intercepting mesh 17, aligned with the exhaust port 16, is welded to the inner wall of the double cone cylinder 1. The intercepting mesh 17 has a porous structure. A rotating exhaust pipe 11, protruding outward and aligned with the exhaust port 16, is integrally formed on the inner wall of the double cone cylinder 1. A fixed exhaust pipe 12 is rotatably installed at the output end of the rotating exhaust pipe 11. An impact mechanism is fixedly installed inside the double cone cylinder 1.

[0023] In this embodiment: First, the raw material is squeezed into the inside of the double cone cylinder 1, then the feed port of the double cone cylinder 1 is closed, and then the air pump connected to the fixed exhaust pipe 12 is started. The air pump extracts the gas inside the double cone cylinder 1. After the gas extraction is completed, the valve on the fixed steam inlet pipe 9 is opened. At this time, high temperature steam enters the inside of the rotating steam inlet pipe 7 through the fixed steam inlet pipe 9 and enters the clamping cavity 6 to heat the inside of the double cone cylinder 1. After heating, it is discharged from the fixed steam outlet pipe 10 through the rotating steam outlet pipe 8.

[0024] In the above process, the driving device (such as a motor, large pulley, or transmission belt) drives the small pulley mounted on the outer periphery of the rotating steam inlet pipe 7 to rotate. The rotating steam inlet pipe 7 then drives the double cone cylinder 1 to rotate, causing the material to sway inside the double cone cylinder 1. During the up-and-down swaying of the material, it comes into contact with the impact mechanism. In this process, the clumps of material are more easily dispersed after contact with the impact mechanism, and thus are heated better. During the heating process, the moisture in the raw material is heated and evaporated to form water vapor. The continuously running air pump draws out the water vapor, which is then extracted through the rotating exhaust pipe 11 and the fixed exhaust pipe 12. During this process, the porous intercepting net 17 intercepts the material to prevent it from being discharged along with the water vapor.

[0025] The impact mechanism includes a fixed ring 13 fixedly installed on the inner wall of the rotating steam inlet pipe 7. The fixed ring 13 has a porous structure, and a connecting shaft 14 is fixedly installed at the center of the fixed ring 13. The end of the connecting shaft 14 away from the fixed ring 13 is fixedly connected to the center of one end of the interception net 17. The outer wall of the connecting shaft 14 is press-fitted with an impact disk 15.

[0026] In this embodiment: during the rotation of the double cone cylinder 1, the rotating steam inlet pipe 7 and the porous intercepting net 17 work together to drive the connecting shaft 14 to rotate synchronously. The connecting shaft 14 also drives multiple collision discs 15 to rotate. At this time, the material that is shaken up and down fully contacts the collision discs 15, thereby assisting the agglomerated material to be further and quickly broken up.

[0027] A rotating cover plate 2 is rotatably installed on the top of the feed inlet of the double cone cylinder 1. A support ear is welded to the bottom of the feed inlet of the double cone cylinder 1. A locking bolt 4 is rotatably installed on the inner side of the support ear. A locking nut 5 is threaded on the outer wall of the locking bolt 4. A sealing ring is installed at the contact position between the rotating cover plate 2 and the feed inlet of the double cone cylinder 1.

[0028] In this embodiment: when the raw material is added into the double cone cylinder 1, the rotating cover plate 2 can be opened by loosening the locking nut 5 and then rotating the locking bolt 4 downwards, so that the material can be added into the double cone cylinder 1. After the material is added, the rotating cover plate 2 is closed, and then the locking bolt 4 is rotated upwards and the locking nut 5 is tightened to press the rotating cover plate 2. At this time, the sealing ring is deformed, effectively sealing the contact position between the two.

[0029] A pressure gauge 3 is installed at the top center of the rotating cover plate 2, penetrating into the inner cavity of the double cone cylinder 1. The sensing end of the pressure gauge 3 is located in the inner cavity of the double cone cylinder 1.

[0030] In this embodiment, the internal air pressure of the double cone 1 can be observed by the air pressure gauge 3, so as to avoid the problem that the internal pressure of the double cone 1 is not up to standard and cannot be detected in time during the air extraction process.

[0031] The output end of the fixed exhaust pipe 12 is connected to the air pump, and a valve is installed on the fixed exhaust pipe 12.

[0032] In this embodiment: when the device is not in operation, the valve is closed to prevent external impurities from entering the interior of the double cone 1 through the fixed exhaust pipe 12 and the rotating exhaust pipe 11.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
