Abstract
Description
Technical Field
[0001] This utility model relates to the field of feed processing technology, specifically a rotary drum drying device for feed. Background Technology
[0002] In the process of feed production, feed often needs to be dried to facilitate better packaging and storage. Currently, the industry uses rotary dryers for large-scale feed drying. In a rotary dryer, feed enters from one end of the drum and exits from the other, enabling continuous drying. Hot air is continuously supplied to the rotating drum, exchanging heat with the moist feed inside. This causes the moisture in the feed to evaporate and be expelled from the drum with the air. Furthermore, the lifting plates inside the drum lift the feed during rotation, preventing it from accumulating and ensuring efficient heat exchange between the feed and the hot air, thus effectively improving drying efficiency.
[0003] In existing rotary dryers, the lifting plates inside the drum are mostly welded and fixed directly inside. After long-term use, it is inconvenient to replace the lifting plates when they are severely worn or deformed. In addition, some feed will stick to the inner wall of the drum or the ends of the lifting plates during the drying process. Traditional rotary drums only have openings at both ends, which makes it difficult to clean the feed adhering inside. This needs to be improved. Utility Model Content
[0004] The purpose of this invention is to provide a rotary drum drying device for feed to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

An industrial hot air blower and a feeding hopper are fixedly mounted on the outer wall of the front cover, and a discharge hopper is provided at the bottom of the rear cover. Several lifting plates are provided inside the rotary drum, and multiple cover plates are installed through inspection ports on the outer wall of the rotary drum. The cover plates are detachably connected to the rotary drum by bolts. Multiple screws are fixedly connected to the outer walls of the lifting plates. Through holes adapted to the screws are provided through the outer walls of the rotary drum and the cover plates, and nuts are connected to the screws after they pass through the corresponding through holes.
[0007] As a further embodiment of this utility model: the industrial hot air blower is installed on the end face of the front cover, and an exhaust fan is installed on the end face of the rear cover. The air outlet of the exhaust fan is connected to the air inlet of the industrial hot air blower through a return pipe, and a gas-liquid separator is installed on the return pipe.
[0008] As a further embodiment of this utility model: a filter mechanism is provided inside the rear cover, and the filter mechanism is located between the discharge hopper and the air inlet of the induced draft fan.

[0013] In this invention, when a large amount of feed adheres to the inside of the rotary drum and needs to be cleaned, or when some lifting plates need to be replaced due to excessive wear or deformation, it is only necessary to remove the cover plate at the appropriate position on the rotary drum. The cleaning equipment can then be inserted into the rotary drum through the inspection port, or the lifting plates can be inserted or removed through the inspection port.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-4 In this embodiment of the present invention, a rotary drum drying device for feed includes a frame 1, a rotary drum 2 rotatably mounted on the top of the frame 1, the rotary drum 2 being inclined, a reduction motor 14 for driving the rotary drum 2 being fixedly mounted on the frame 1, and a front cover 3 and a rear cover 4 rotatably sleeved at both ends of the rotary drum 2, respectively. Both the front cover 3 and the rear cover 4 are fixedly connected to the frame 1. An industrial hot air blower 5 and a feeding hopper 6 are fixedly mounted on the outer wall of the front cover 3. The bottom of the rear cover 4 is provided with a discharge hopper 7. The rotating drum 2 is provided with a number of lifting plates 18. The outer wall of the rotating drum 2 is provided with a number of cover plates 17 through the inspection port 16. The cover plates 17 are detachably connected to the rotating drum 2 by bolts. The outer wall of the lifting plates 18 is fixedly connected with a number of screws 19. The outer walls of the rotating drum 2 and the cover plates 17 are provided with through holes adapted to the screws 19. The screws 19 are connected with nuts 20 after passing through the corresponding through holes.
[0021] By adopting the above-mentioned solution, when using this utility model, after starting the industrial hot air blower 5 to send hot air into the rotating drum 2, the geared motor 14 is started to drive the rotating drum 2 to rotate, and the feed is fed into the rotating drum 2 through the feeding hopper. During the rotation of the rotating drum 2, the lifting plate 18 will continuously lift the feed so that the feed comes into contact with the hot air, thereby gradually drying the feed. The feed will move continuously along the inclined rotating drum 2 towards the rear cover 4 until it is discharged from the discharge hopper 7, thereby realizing the continuous drying operation of the feed.
[0022] When a large amount of feed adheres to the inside of the rotating drum 2 and needs to be cleaned, or when some lifting plates 18 need to be replaced due to excessive wear or deformation, simply remove the cover plate 17 at the appropriate position on the rotating drum 2. The cleaning equipment can then be inserted into the rotating drum 2 through the inspection port 16, or the lifting plates 18 can be inserted or removed through the inspection port 16. The screw 19, through the hole, and nut 20 facilitate the disassembly and assembly of the lifting plates 18 on the rotating drum 2 and the cover plate 17. The operation is simple and convenient, greatly improving the maintenance efficiency of the rotating drum dryer.
[0023] Specific combination Figure 1 and Figure 2 In one embodiment of this utility model, the industrial hot air blower 5 is installed on the end face of the front cover 3, and the end face of the rear cover 4 is equipped with an exhaust fan 8. The air outlet of the exhaust fan 8 is connected to the air inlet of the industrial hot air blower 5 through a return pipe 9, and a gas-liquid separator 10 is installed on the return pipe 9.
[0024] By setting the induced draft fan 8, the humid hot air can be drawn at the rear end of the rotating drum 2 and introduced into the return pipe 9. After the hot air in the return pipe 9 passes through the gas-liquid separator 10, most of the water vapor can be removed. Then the hot air flows back to the industrial hot air fan 5 and is sent back into the rotating drum 2 to improve the utilization rate of hot air and save energy.
[0025] Specific combination Figure 2 and Figure 4 In one embodiment of the present invention, a filter mechanism is provided inside the rear cover 4, and the filter mechanism is located between the discharge hopper 7 and the air inlet of the blower 8.

Two baffles 26 are fixedly connected between the two partitions 24, and the two baffles 26 are located on the upper and lower sides of the frame 21, respectively.
[0027] The filter screen 22 reduces feed dust that enters the blower 8 with the humid and hot air. The two partitions 24 and the baffle 26 facilitate the positioning and installation of the frame 21 and the filter screen 22 inside the rear cover 4, making the operation simple and convenient.
