Description

Technical Field

[0001] This utility model relates to the technical field of three-cylinder dryers, specifically a horizontal three-cylinder dryer. Background Technology

[0002] Existing equipment utilizes hot air generated by a hot air furnace, which is purified by a high-efficiency dust collector before being sent into the drum of the equipment. The material undergoes sufficient heat and mass exchange. The hot air rapidly evaporates the moisture in the material and discharges the water vapor from the dryer. Simultaneously, the material tumbles continuously inside the drum, making full contact with the hot air and accelerating the drying speed. However, when heat is lost inside the drum or the temperature does not meet the standard, it is necessary to monitor the temperature inside the drum and the water vapor at the outlet to determine whether heating is required. This is to prevent the material from being incompletely dried inside the dryer and to take timely remedial action. Therefore, a horizontal three-drum dryer that solves the above problems is needed. Utility Model Content

[0013] 1. This horizontal three-cylinder dryer, through the setting of connecting pipes, temperature detection sensors, fans, air troughs, and other structures, allows the air inlet on the device to deliver hot air into the device after connecting to the hot air furnace for drying. When the heating effect is insufficient, the temperature detection sensor detects the temperature value inside the device, and the connecting pipe guides the hot air back into the space between the outer and middle cylinders. The secondary introduction of hot air is used for reheating, thereby accelerating the hot air through the air troughs into the device, thus completing the drying of the material.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-5 A horizontal three-cylinder dryer includes: an outer cylinder 1, a side sealing ring 2 fitted onto the outer wall of the outer cylinder 1, a fixed base 3 installed at the bottom of the outer cylinder 1, a roller motor 4 installed at the top of the fixed base 3, a limiting circle 5 on the outer wall of the roller motor 4, a middle cylinder 6 fitted into the inner cavity of the outer cylinder 1, an inner cylinder 7 fitted into the inner cavity of the outer cylinder 1, a polygonal connecting frame 8 connected to the inner wall of the outer cylinder 1, a lifting plate 9 connected to the inner wall of the outer cylinder 1, a lifting plate 10 connected to the inner wall of the middle cylinder 6, a lifting plate 11 connected to the inner wall of the inner cylinder 7, an air groove 12 formed on the outer wall of the outer cylinder 1, a fixed wall 13 connected to the outer wall of the outer cylinder 1, and a fixed base 14 installed at the bottom of the outer cylinder 1. A support wheel 15 is movably connected to the top of the fixed base 14. A fixing ring 16 is movably sleeved on the outer wall of the outer cylinder 1. An installation box 17 is connected to the outer wall of the fixing ring 16. A connecting pipe 18 is connected to the outer wall of the installation box 17. A temperature detection sensor 19 is connected to the outer wall of the installation box 17. A support rod 20 is provided on the side of the outer cylinder 1. An air inlet device 21 is installed on the top of the support rod 20. An air inlet 22 is connected to the outer wall of the air inlet device 21. A material guide groove 23 is connected to the outer wall of the air inlet device 21. An air outlet device 24 is sleeved on the outer wall of the side sealing ring 2. A discharge port 25 is provided at the bottom of the air outlet device 24. A water vapor sensor 26 is installed on the outer wall of the air outlet device 24.

[0023] The diameter of the limiting circle 5 is larger than the diameter of the towing motor 4, and the limiting circle 5 is set at both ends of the towing motor 4. By making the diameter of the limiting circle 5 larger than the diameter of the towing motor 4, the limiting circle 5 on the device is set on both sides of the towing motor 4. The length of the towing motor 4 is the same as the length of the side sealing ring 2. When the outer cylinder 1 and the side sealing ring 2 need to rotate, the towing motor 4 drives them. The limiting circle 5 on both sides of the towing motor 4 limits the outer wall of the side sealing ring 2, preventing the outer cylinder 1 and the side sealing ring 2 from gradually detaching from the device.

[0024] Among them, lifting plate 19, lifting plate 20 and lifting plate 31 have the same shape, and lifting plate 19 and lifting plate 31 have the same direction. Because lifting plate 19, lifting plate 20 and lifting plate 311 have the same shape, lifting plate 19 and lifting plate 311 are set on the inner and outer sides of lifting plate 20. Lifting plate 19, lifting plate 20 and lifting plate 311, together with outer cylinder 1, middle cylinder 6 and inner cylinder 7, form an inner cavity "Z" shaped transmission, so that the material in the device can flow in a "Z" shape in the device.

[0025] The polygonal connecting frame 8 is located at the center of the device and extends outward to connect the outer cylinder 1, the middle cylinder 6 and the inner cylinder 7. By setting the polygonal connecting frame 8 at the center of the device, the polygonal connecting frame 8 is fixedly connected to the outer cylinder 1, the middle cylinder 6 and the inner cylinder 7 in the inner cavity of the device, so that when the outer cylinder 1 rotates, the middle cylinder 6 and the inner cylinder 7 rotate synchronously with the outer cylinder 1.

[0026] The temperature sensor 19 extends into the inner cavity between the fixed ring 16 and the outer cylinder 1, and the air grooves 12 are evenly distributed on the outer wall of the outer cylinder 1. The air grooves 12 are evenly distributed on the outer wall of the outer cylinder 1, so that the temperature in the inner cavity of the outer cylinder 1 can be conducted to the space between the fixed ring 16 and the outer cylinder 1 through the air grooves 12. This allows the temperature sensor 19 to detect the temperature of the cavity between the fixed ring 16 and the outer cylinder 1 and obtain the temperature value inside the device.

[0027] The air outlet device 24 is located on the other side away from the air inlet 22, and the air inlet 22 is connected to the air outlet device 24 through the outer cylinder 1. Since the air outlet device 24 is located on the other side away from the air inlet 22, the hot air generated by the hot blast stove enters the air inlet 22, passes through the inner cavity of the outer cylinder 1, and finally reaches the air outlet device 24, where it is discharged outward.

[0028] The water vapor sensor 26 is installed on one side of the air outlet device 24, and the metal detection rod of the water vapor sensor 26 extends into the inner cavity of the air outlet device 24. By installing the water vapor sensor 26 on one side of the air outlet device 24, the air outlet device 24 can detect the water vapor in the air when the hot air is about to be discharged, thereby understanding the hot air drying effect in the device and determining whether the hot air power needs to be increased.

[0029] The inner wall of the mounting box 17 is connected to a fan 27, which is located at the connection between the connecting pipe 18 and the mounting box 17. The fan 27 is connected to the inner wall of the mounting box 17, so that when the connecting pipe 18 supplies air to the device, the hot air is drawn into the device by the connecting pipe 18 and flows into the device more quickly. This allows the hot air output from the connecting pipe 18 to pass through the air groove 12 and enter the device.

[0030] The working principle is as follows: First, by setting up a water vapor sensor 26, an air outlet device 24, a connecting pipe 18, and a temperature detection sensor 19, the water vapor sensor 26 on the device detects moisture in the dried material at the air outlet device 24, assisting the operator in inspecting the material after drying. If an abnormality in moisture is detected, hot air is immediately introduced through the connecting pipe 18 for remedial operation, thus avoiding waste or re-returning of material in the drum. Then, by setting up a connecting pipe 18, a temperature detection sensor 19, a fan 27, and an air trough 12, the air inlet 22 on the device supplies hot air into the device after connecting to the hot air furnace for drying. If the heating effect is insufficient, the temperature detection sensor 19 detects the temperature value inside the device, and the connecting pipe 18 guides the hot air again into the space between the outer drum 1 and the middle drum 6. The secondary introduction of hot air is used for reheating, thereby accelerating the hot air through the air trough 12 into the device, thus completing the drying of the material.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
