[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-4 This utility model provides a feeding device for a double cone rotary vacuum dryer, including a screw feeder 1, a base 2 rotatably connected to the bottom of the screw feeder 1, an adjustment component for changing the height of the discharge port of the screw feeder 1 between the two sides of the base 2, a cloth bag 4 fixed to the discharge end of the screw feeder 1 by a clamp, a discharge head 5 fixed to the other end of the cloth bag 4 by a clamp, and one end of the discharge head 5 inserted into the manhole of the dryer. A limiting component for positioning the position of the screw feeder 1 is provided on one side of the base 2.

[0024] The bag 4 is made of wear-resistant nylon material, which can effectively buffer the impact when the material falls and prevent dust from flying during the material transfer process. The end of the feeding head 5 is flared, which can be better inserted into the manhole. The outer wall is fitted with a conical rubber sealing ring, which can form a good seal after being inserted into the manhole of the dryer, further improving the airtightness of the feeding process.

[0025] In use, the positions of the base 2 and the screw feeder 1 are positioned by the limiting component, and the height of the discharge end of the screw feeder 1 is changed by the adjusting component, so that the discharge head 5 is located obliquely above the manhole. Then, the height of the discharge head 5 is lowered by the adjusting component, so that one end of the discharge head 5 is inserted into the manhole. The screw feeder 1 is started, and the screw feeder 1 will drive the material to move, so that the material enters from the feed end and exits from the discharge end. The discharged material will pass through the cloth bag 4 and enter the discharge head 5, and then enter the dryer. Since the material discharge is in a closed state, all the material can fall into the dryer, which improves the utilization rate of material feeding and effectively avoids the resource waste and environmental pollution problems caused by material scattering or dust leakage in traditional feeding methods.

[0026] In addition, the feed end of the screw feeder 1 is equipped with a detachable filter screen, which can initially filter large impurities in the material to prevent them from entering the screw and causing jamming or equipment damage, thus further ensuring the stability and continuity of the feeding process.

[0027] In this utility model, the adjustment component includes a slide 8 that slides on the bottom of the base 2, a support 3 that is rotatably connected to the top of the slide 8, and the support 3 is rotatably connected to the screw feeder 1. The bottom of the base 2 is provided with a power component that drives the slide 8 to move horizontally.

[0028] The power assembly drives the slide 8 to move horizontally on the base 2, thereby squeezing one end of the support frame 3, causing the support frame 3 to rotate with the screw feeder 1, thus rotating the screw feeder 1 and changing the tilt angle of the screw feeder 1. This allows for adjustment of the height of the discharge head 5, adapting to the manhole position requirements of different dryer specifications and improving the versatility and practicality of the equipment.

[0029] Furthermore, the power assembly includes a lead screw 9 that rotates between the inner walls on both sides of the base 2, and the lead screw 9 passes through the slide 8 and is threadedly connected to the slide 8. One end of the lead screw 9 passes through the base 2 and has an internal hexagonal groove.

[0030] By using a hand drill and an internal hexagonal drill bit, inserting the internal hexagonal drill bit into the hexagonal slot, and starting the hand drill, the hand drill drives the lead screw 9 to rotate, thereby moving the slide 8 horizontally. This can be done with a simple hand drill without the need for complicated large tools, greatly reducing the difficulty of adjustment and improving the convenience of operation. It allows the staff to quickly adapt the equipment to the actual manhole height of the dryer, effectively saving equipment debugging time.

[0031] The limiting component includes two fixing blocks 14 welded to the inner wall of the bottom of the base 2. One side of the fixing block 14 has a through hole, and a sliding rod 15 is slidably connected in the through hole. One end of the sliding rod 15 is welded to a baffle 11, and a rubber pad 12 is glued to one side of the baffle 11. The rubber pad 12 will buffer the collision between the baffle 11 and the dryer to prevent the dryer from being damaged by the collision. The top of the fixing block 14 is provided with a locking component to fix the sliding rod 15.

[0032] Slide the slide bar 15, and after the slide bar 15 moves a certain distance, use the locking assembly to fix the slide bar 15. Then push the base 2 so that the rubber pad 12 on one side of the baffle 11 contacts the dryer, thereby positioning the distance between the base 2 and the dryer, and thus quickly positioning the discharge head 5. This ensures that the discharge head 5 can be accurately aligned with the manhole position, avoids multiple adjustments of the base 2 which would reduce the feeding efficiency, and improves the positioning efficiency of the device.

[0033] Furthermore, the locking assembly includes a threaded hole on the top of the fixing block 14, a fixing screw 13 is threaded into the threaded hole, and one end of the fixing screw 13 contacts the slide bar 15.

[0034] When it is necessary to fix the slide rod 15, rotate the fixing screw 13 so that one end of the fixing screw 13 contacts the slide rod 15, and use friction to fix the slide rod 15, preventing the slide rod 15 from sliding during the operation of the equipment and ensuring the stability of the limiting effect.

[0035] Furthermore, connecting brackets 10 are welded to the outer circumference of the two slide rods 15, and scales 16 are provided on one side of each slide rod 15 to determine the extension length of the slide rod 15.

[0036] The connecting frame 10 enhances the connection strength between the two slide rods 15, preventing bending or displacement of a single slide rod 15 under force, and ensuring synchronous movement of the two slide rods 15, thereby ensuring the stability of the baffle 11 when in contact with the dryer. The scale 16 provides operators with an intuitive length reference. When sliding the slide rod 15, the extension distance of the slide rod 15 can be quickly determined by observing the scale 16 without repeated measurement, further improving the convenience and accuracy of positioning operation. This allows different operators to easily achieve uniform control of the extension length of the slide rod 15 by referring to the scale 16 when using the device, reducing the impact of human operation errors on the positioning effect.

[0037] Among them, the discharge end of the screw feeder 1 and the outer circumference of the feeding head 5 are both welded with fixed frames 6, and the two fixed frames 6 are fixed with elastic plates 7 by bolts. The elastic plates 7 are made of spring steel with a high elastic coefficient.

[0038] The elastic plate 7 can assist in limiting the feeding head 5 and prevent the rotation of the feeding head 5. When the height or angle of the screw feeder 1 changes through the adjustment component, the elastic plate 7 will adapt accordingly to avoid the feeding head 5 or the bag 4 being pulled and damaged due to rigid connection. At the same time, the spring steel material has excellent fatigue resistance and can maintain stable elastic support force in long-term repeated deformation, further extending the overall service life of the device.

[0039] The working principle of this utility model:

[0040] Using a hand drill and an internal hexagonal drill bit, insert the internal hexagonal drill bit into the hexagonal slot, start the hand drill, the hand drill drives the lead screw 9 to rotate, thereby driving the slide 8 to move horizontally, thereby squeezing one end of the support frame 3, causing the support frame 3 to rotate with the screw feeder 1, thereby causing the screw feeder 1 to rotate, and raising the discharge end of the screw feeder 1;

[0041] Slide the slide bar 15, quickly determine the extension distance of the slide bar 15 by observing the scale 16, determine the distance that needs to be set between the base 2 and the dryer, rotate the fixing screw 13 so that one end of the fixing screw 13 contacts the slide bar 15, and fix the slide bar 15 by friction.

[0042] Push the base 2 so that the rubber pad 12 on one side of the baffle 11 comes into contact with the dryer, thereby positioning the distance between the base 2 and the dryer, and thus quickly positioning the discharge head 5 to ensure that the discharge head 5 can be accurately aligned with the manhole position.

[0043] Using a hand drill and an internal hexagonal drill bit, insert the internal hexagonal drill bit into the hexagonal slot, start the hand drill, the hand drill drives the screw 9 to rotate, thereby driving the slide 8 to move horizontally, thereby squeezing one end of the support frame 3, causing the support frame 3 to rotate with the screw feeder 1, thereby causing the screw feeder 1 to rotate, causing the discharge end of the screw feeder 1 to descend, and then causing one end of the discharge head 5 to be inserted into the manhole;

[0044] When the screw feeder 1 is started, it will move the material, allowing it to enter from the feed end and exit from the discharge end. The discharged material will pass through the cloth bag 4 and enter the discharge head 5, and then enter the dryer. Since the material discharge is in a closed state, all the material can fall into the dryer, improving the utilization rate of material feeding and effectively avoiding the resource waste and environmental pollution caused by material scattering or dust leakage in traditional feeding methods.

[0045] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
