Description

Technical Field

[0001] This utility model belongs to the field of sludge treatment technology, specifically relating to a discharge adjustment device for a disc dryer. Background Technology

[0002] In sludge treatment, disc dryers are commonly used equipment, and the rationality of their discharge adjustment directly affects the drying effect and the smooth progress of subsequent processes. Currently, there are two main solutions for discharging adjustment in disc dryers, along with their corresponding drawbacks: Existing Solution 1: A hole is drilled at the bottom of the disc dryer and a slide gate valve is installed. The discharge rate is controlled by adjusting the opening of the slide gate valve. However, this method has low precision in controlling the discharge rate, resulting in poor uniformity of the discharge, making it difficult to meet the processing scenarios with high requirements for material dryness and flow rate.

[0003] Existing Option 2: An opening is made at the bottom of the disc-type dryer and a discharge screw conveyor is installed. The conveying volume is changed by adjusting the speed of the screw conveyor, thereby achieving discharge regulation. However, this option is not well-suited for viscous materials or materials containing impurities, and is prone to problems such as screw conveyor blockage and material accumulation, affecting the normal operation of the dryer.

[0004] Furthermore, both of the aforementioned existing solutions share a common drawback: poor visibility of the material output from the dryer. Workers cannot directly observe the moisture content of the output material, nor can they promptly detect material accumulation or blockages. This not only hinders timely adjustments to process parameters to ensure drying effectiveness but also increases the difficulty and cost of cleaning and maintenance, ultimately reducing equipment operating efficiency.

[0018] Preferred embodiment.

[0019] like Figure 1-2 As shown, this utility model discloses a discharge adjustment device for a disc dryer, including a discharge port 1, an observation window 2, a baffle plate driving mechanism, and a baffle plate 21. The baffle plate driving mechanism is used to drive the baffle plate 21 to move up and down to adjust the discharge, wherein: The baffle plate drive mechanism includes a gear cover 3, a transmission shaft 1 4, a handwheel 5, a gear 1 6, an operating end seat 1 7, a knob plunger 8, a lead screw sleeve 9, a pointer 10, a guide rod 11, a scale 12, an operating end seat 2 13, a bevel gear 14, a bevel gear 15, a first bearing with a mounting seat 161, a second bearing with a mounting seat 162, a gear 2 17, a transmission shaft 2 18, a cylindrical rack 19, a rack guide tube 20, and a limiting nut 23, wherein: The No. 1 drive shaft 4 is mounted between the No. 1 operating end seat 7 and the No. 2 operating end seat 13 via two first bearings 161. The handwheel 5 and the bevel gear 14 are respectively fixed at both ends of the No. 1 drive shaft 4. The No. 2 drive shaft 18 is mounted on the gear cover 3 via two second bearings 162. The bevel gear 15 and the two No. 2 gears 17 are all fixed on the No. 2 drive shaft 18, and the bevel gear 15 meshes with the bevel gear 14. Two rack guide tubes 20 are fixed on the gear cover 3; two cylindrical racks 19 pass through the upper and lower guide holes of the gear cover 3 and then pass through the two rack guide tubes 20 respectively, and mesh with the two No. 2 gears 17 respectively. The upper end of the cylindrical rack 19 is provided with a limit nut 23; the baffle plate 21 is installed in the baffle plate track 24 and can move up and down in the baffle plate track 24. The lower end of the baffle plate 21 is connected to the two cylindrical racks 19 respectively through two connecting blocks 22.

[0020] Specifically, the discharge adjustment device of the disc dryer is fixed on the side of the disc dryer cylinder 25. The side opening of the disc dryer cylinder 25 is connected to the discharge adjustment device. The dry material is discharged after being adjusted by the side opening and the baffle plate 21.

[0021] More specifically, the observation window 2 is set on the discharge port 1 to observe the moisture content of the material discharged from the dryer.

[0022] Furthermore, the lead screw sleeve 9 is fixed on the No. 1 transmission shaft 4, and the pointer 10 has an internal thread and meshes with the lead screw sleeve 9; the pointer 10 has a hole, and the guide rod 11 is fixed on the No. 1 operating end seat 7 and passes through the hole of the pointer 10; the scale 12 is fixed on the discharge port 1, and the current height of the baffle plate 21 can be determined by the position indicated by the pointer 10.

[0023] Furthermore, the No. 1 gear 6 is fixed on the No. 1 transmission shaft 4, and the knob plunger 8 is fixed on the No. 1 operating end seat 7; the knob plunger 8 is provided with a telescopic pin, which is used to insert between the teeth of the No. 1 gear 6 to lock the rotation of the No. 1 transmission shaft 4.

[0024] Regarding this utility model: In actual use, when it is necessary to adjust the height of the baffle plate 21, the operator first retracts the pin of the knob plunger 8 to release the lock on the No. 1 drive shaft 4. Then, the handwheel 5 is turned clockwise or counterclockwise. The handwheel 5 drives the No. 1 drive shaft 4 to rotate, which in turn drives the bevel gear 14 and the lead screw sleeve 9 to rotate. The rotation of the bevel gear 14 drives the bevel gear 15, which in turn drives the No. 2 drive shaft 18 and the No. 2 gear 17 to rotate. The rotation of the No. 2 gear 17 drives the cylindrical rack 19, which meshes with it, to move up or down linearly along the rack guide tube 20. The cylindrical rack 19 drives the baffle plate 21 to move up and down synchronously within the baffle plate track 24 through the connecting block 22.

[0025] During the rotation of the lead screw sleeve 9, the pointer 10 is restricted by the guide rod 11 and cannot rotate with the lead screw sleeve 9. Therefore, the pointer 10 will move in a straight line along the guide rod 11. By observing the position indicated by the pointer 10 on the scale 12, the operator can accurately determine the current height of the baffle plate 21. After the baffle plate 21 is adjusted to the required height, the operator inserts the pin of the knob plunger 8 into the teeth of gear 6 to lock the rotation of the transmission shaft 4, thereby keeping the baffle plate 21 at the current height and achieving stable control of the output.

[0026] Staff can observe the moisture content of the material discharged from the dryer at any time through the observation window 2 on the discharge port 1. If the moisture content is found to be unacceptable, the height of the baffle plate 21 can be adjusted in a timely manner according to the above operating steps. When material accumulation or debris blockage occurs, cleaning and maintenance can also be carried out through the observation window 2.

[0027] The discharge adjustment device of the disc dryer in this embodiment can effectively improve the uniformity of discharge, enhance the adaptability to viscous materials or materials containing impurities, and improve the visibility of discharge, making it convenient for staff to grasp the equipment operating status in a timely manner and perform corresponding operations, thus ensuring the stable and efficient operation of the disc dryer.

[0028] It is worth mentioning that the technical features such as the disc dryer cylinder involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0029] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
