Abstract
Description
Technical Field
[0001] The utility model relates to a double-sided drum device with intermediate forced exhaust, in particular to a double-sided drum device with intermediate forced exhaust, which has an intermediate forced exhaust component and can exhaust air in the shortest distance and can use a low-power exhaust fan with low cost. Background Art
[0002] A drying device with a drying design is known (for example, the natural gas transmission mechanism and method in the activated alumina production drying process of Chinese invention patent No. CN115654867), which basically includes connecting an air intake pipe and an exhaust pipe at both ends of a drum dryer, so that air can be taken in and exhausted to facilitate the production of activated alumina.
[0003] The above-mentioned known device causes the following problems:
[0004] [1] The exhaust pipe has a long exhaust distance and a poor exhaust effect. The exhaust pipe of the known device is set at one end of the drum, which means that the long drum must be evacuated, and the exhaust effect is quite limited. Even if only half of the drum is evacuated, the effect is still poor. Therefore, the exhaust pipe has a long exhaust distance and a poor exhaust effect.
[0005] [2] A high-power exhaust fan must be used, which is more expensive. Since the exhaust pipe is installed at one end of the drum, if you want to exhaust air from a long drum, you may have to install a high-power exhaust fan, which will increase the cost. Therefore, a high-power exhaust fan must be used, which is more expensive.
[0006] In view of this, it is necessary to develop a technology that can solve the above-mentioned existing shortcomings. Utility Model Content
[0007] In order to solve the problems that the exhaust pipe has a long exhaust distance and a poor exhaust effect, and that a high-power exhaust fan must be used at a high cost, the utility model provides a double-sided drum device with intermediate forced exhaust, which has the advantages that the intermediate forced exhaust component can exhaust air at the shortest distance, and a low-power exhaust fan can be used at a low cost.
[0008] The technical solution adopted by the utility model to solve its technical problems is:
[0009] A double-sided drum device with intermediate forced exhaust, comprising:
[0010] The first drum has a first feed inlet, a first discharge outlet, a plurality of first pusher elements, a first barrel space and an air inlet pipe that are interconnected; the first feed inlet and the first discharge outlet are coaxial with the first drum, the plurality of first pusher elements are arranged in the first barrel space, and are distributed in the barrel wall of the first drum along the first feed inlet toward the first discharge outlet. The air inlet pipe connects the outside world with the first barrel space, and is located at the end of the first drum corresponding to the first feed inlet;
[0011] A first power assembly is provided corresponding to the first drum, and the first power assembly includes a first base frame and a first power device. The first base frame is used to carry the first drum. The first power device is provided on the first base frame and is used to drive the first drum to rotate relative to the first base frame and to rotate coaxially with the first feed port.
[0012] The second drum has a second feed inlet, a second discharge outlet, a plurality of second pusher elements and a second drum space that are connected to each other; the second feed inlet and the second discharge outlet are coaxial with the second drum, the plurality of second pusher elements are arranged in the second drum space and are distributed in the drum wall of the second drum along the second feed inlet toward the second discharge outlet, and the second feed inlet is used to coaxially connect with the first discharge outlet;
[0013] A second power assembly is provided corresponding to the second drum, and the second power assembly includes a second base frame and a second power device. The second base frame is used to carry the second drum. The second power device is provided on the second base frame to drive the second drum to rotate relative to the second base frame and to rotate coaxially with the first discharge port.
[0014] A feed assembly is provided corresponding to the first feed inlet and is used to feed the object to be processed from the first feed inlet into the space inside the first barrel;
[0015] A forced air intake assembly is provided corresponding to the air intake pipe.

[0017] Thereby, when the first power component and the second power component are used to drive the first drum and the second drum to rotate relative to the intermediate forced exhaust component respectively, the first pushing elements and the second pushing elements are used to stir the object to be processed respectively. The stirring process simultaneously forces the object to be processed to be pushed from the first feed port through the space inside the first barrel, the first discharge port, the intermediate forced exhaust component, the second feed port, and the space inside the second barrel toward the second discharge port, and the hot air is mixed in to increase the temperature to enhance the fermentation effect. The forced exhaust structure can force the discharge of excess gas generated during the fermentation process from between the first drum and the second drum.

[0044] See also Figure 1 , Figure 2 , Figure 3A , Figure 3B , Figure 4 , Figure 5 , Figure 6 and Figure 7 The utility model is a double-sided drum device with intermediate forced exhaust, which includes:
[0045] The first drum 10 has a first material inlet 11, a first material outlet 12, a plurality of first material pushing elements 13, a first barrel space 14 and an air inlet pipe 15. The first material inlet 11 and the first material outlet 12 are coaxial with the first drum 10. The plurality of first material pushing elements 13 are arranged in the first barrel space 14 and are distributed in the barrel wall of the first drum 10 along the first material inlet 11 toward the first material outlet 12. The air inlet pipe 15 connects the outside with the first barrel space 14 and is located at the end of the first drum 10 corresponding to the first material inlet 11.
[0046] The first power assembly 20 is provided corresponding to the first drum 10, and includes a first base frame 21 and a first power device 22. The first base frame 21 is used to carry the first drum 10. The first power device 22 is provided on the first base frame 21 to drive the first drum 10 to rotate relative to the first base frame 21, and to rotate coaxially with the first feed port 11.
[0047] The second drum 30 has a second feed port 31, a second discharge port 32, a plurality of second pushing elements 33 and a second drum space 34 that are interconnected; the second feed port 31 and the second discharge port 32 are coaxial with the second drum 30, the plurality of second pushing elements 33 are arranged in the second drum space 34, and are distributed in the drum wall of the second drum 30 along the second feed port 31 toward the second discharge port 32; the second feed port 31 is used to coaxially connect with the first discharge port 12.
[0048] The second power assembly 40 is provided corresponding to the second drum 30 , and includes a second base frame 41 and a second power device 42 . The second base frame 41 is used to carry the second drum 30 . The second power device 42 is provided on the second base frame 41 to drive the second drum 30 to rotate relative to the second base frame 41 , and to rotate coaxially with the first discharge port 12 .
[0049] The feed assembly 50 is provided corresponding to the first feed port 11 , and is used for supplying the object to be processed 91 from the first feed port 11 into the first barrel inner space 14 .
[0050] The forced air intake assembly 60 is provided corresponding to the air intake pipe 15 . When the first drum 10 rotates to the air intake pipe 15 to connect with the forced air intake assembly 60 , the forced air intake assembly 60 is used to supply hot air 92 from the air intake pipe 15 to the first drum inner space 14 .
[0051] The intermediate forced exhaust component 70 is fixedly mounted between the first drum 10 and the second drum 30 ; and is coaxially connected to the first discharge port 12 and the second feed port 31 , and rotates relative to the first discharge port 12 and the second feed port 31 respectively; the intermediate forced exhaust component 70 has a forced exhaust structure 71 .
[0052] Thereby, when the first power component 20 and the second power component 40 are used to drive the first drum 10 and the second drum 30 to rotate relative to the intermediate forced exhaust component 70, the first pushing elements 13 and the second pushing elements 33 are used to stir the object 91 to be processed. The stirring process simultaneously forces the object 91 to be processed to be pushed from the first feed port 11 through the first barrel space 14, the first discharge port 12, the intermediate forced exhaust component 70, the second feed port 31, and the second barrel space 34 toward the second discharge port 32, and the hot air 92 is mixed in to increase the temperature and strengthen the fermentation effect. The forced exhaust structure 71 can quickly and forcibly discharge the excess gas 93 generated by the fermentation process from between the first drum 10 and the second drum 30.
[0053] In practice, the air inlet pipe 15 may be a pipe structure extending out of the first barrel space 14 (eg Figure 3A The extended length is determined so as not to affect the rolling of the first drum 10.
[0054] Furthermore, the air intake pipe 15 has at least one air hole 151, and the at least one air hole 151 is opened at a position of the air intake pipe 15 located in the first barrel space 14 (such as Figure 3B shown).
[0055] The forced exhaust structure 71 can be an exhaust fan.
[0056] This case is mainly used in operations that require stirring and forced exhaust.
[0057] The action process is as follows:
[0058] [a] Feeding: The object to be processed 91 is fed from the feeding assembly 50 through the first feeding port 11 into the first barrel inner space 14 .
[0059] [b] Stirring: The first power assembly 20 and the second power assembly 40 are started to drive the first drum 10 and the second drum 30 to rotate relative to the intermediate forced exhaust assembly 70 respectively. During the rotation, the first pushing elements 13 and the second pushing elements 33 are used to stir the object 91 to be processed. While stirring, the object 91 to be processed can be forced to move from the first feed port 11 through the first barrel space 14, the first discharge port 12, the intermediate forced exhaust assembly 70, the second feed port 31 and the second barrel space 34 toward the second discharge port 32.
[0060] [c] Supply of hot air: see Figure 3A, assuming that the first drum 10 can at least drive the air intake pipe 15 to move between the air intake position P1, the first rotation position P2 and the second rotation position P3 (in sequence) during the rolling process. When the air intake pipe 15 is located at the air intake position P1 and connected to the forced air intake assembly 60, the first power assembly 20 can be controlled to suspend the air supply time. During this air supply time, the forced air intake assembly 60 can be started to supply the hot air 92 to the first barrel space 14 through the air intake pipe 15 (and the at least one air hole 151). Since the hot air 92 may be non-directionally dispersed to the first discharge port 12, the intermediate forced exhaust assembly 70, the second feed port 31, the second barrel space 34 and the second discharge port 32, etc., it can be dispersed into the object to be processed 91.
[0061] The hot air 92 can increase the temperature of the object to be processed 91 , the first barrel space 14 , and the second barrel space 34 , thereby helping to promote the fermentation or drying of the object to be processed 91 .
[0062] [d] Forced exhaust: Since the intermediate forced exhaust component 70 is located between the first barrel space 14 and the second barrel space 34, when an excess of the gas 93 (which may be carbon dioxide produced by fermentation) is generated in the first barrel space 14 or the second barrel space 34, the forced exhaust structure 71 can be activated to quickly extract the excess gas 93 from the first barrel space 14 or the second barrel space 34 at the "shortest" distance.
[0063] [e] Finished product: The final finished product 94 is discharged through the second discharge port 32 .
[0064] The advantages and effects of the utility model can be summarized as follows:
[0065] [1] The intermediate forced exhaust assembly can exhaust air over the shortest distance. Since the intermediate forced exhaust assembly is located between the space in the first barrel and the space in the second barrel, when exhausting air from the space in the first barrel, it does not need to pass through the space in the second barrel, and the exhaust distance can be shortened (i.e., the shortest distance). Similarly, when exhausting air from the space in the second barrel, it does not need to pass through the space in the first barrel, and the exhaust distance can also be shortened (i.e., the shortest distance). Therefore, the intermediate forced exhaust assembly can exhaust air over the shortest distance.
[0066] [2] A smaller exhaust fan can be used, which is less expensive. Since the intermediate forced exhaust assembly is located between the space in the first barrel and the space in the second barrel, the distance for exhausting air from either of the spaces is the shortest. Since the air is exhausted over the shortest distance, a smaller exhaust fan can be used, which is less expensive. Therefore, a smaller exhaust fan can be used, which is less expensive.
[0067] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
