DETAILED DESCRIPTION

[0022] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-7 The present invention provides a technical solution: a disturbance feeding type vertical circulating airflow dryer, comprising a drying device and a disturbance feeding mechanism, the drying device comprising a drying chamber 1, a circulation pump 2, an air inlet pipe 3, an air outlet pipe 4, a feed port 5 and a discharge port 6, a feed bin is arranged above the drying device, and the outlet of the feed bin is located above the feed port 5;

[0024] The left and right ends of the circulation pump 2 are connected to the interior of the drying chamber 1 through the air inlet pipe 3 and the air outlet pipe 4, the feed port 5 is installed above the drying chamber 1, and the discharge port 6 is installed below the drying chamber 1. The disturbance unloading mechanism includes a conical baffle chamber 7, and the left and right sides of the conical baffle chamber 7 are fixedly connected to the upper inner wall of the drying chamber 1 with a connecting rod 8, and the bottom of the conical baffle chamber 7 is fixedly installed with a motor 71, and the output end of the motor 71 is fixed with an output rod 72, and the upper end of the output rod 72 is fixed with a spring 1 73, and the upper end of the spring 1 73 is fixedly connected with a stirring shaft 74, and slots are provided on the left and right sides above the stirring shaft 74, and stirring blades 741 are slidably connected in the slots, and a spring 2 742 is connected between the two stirring blades 741;

[0025] The material is discharged from the material bin and the material falls into the drying chamber 1 through the feed port 5. The circulating pump 2 runs, and hot air is input into the drying chamber 1 through the air inlet pipe 3, and then the gas is extracted through the air outlet pipe 4 to perform circulating hot air drying to fully dry the material. During the discharge process, the motor 71 runs, and the output rod 72 drives the spring 73 to rotate. The spring 73 drives the stirring blade 741 to rotate through the stirring shaft 74, thereby breaking up the material. The broken up material slides into the drying chamber 1 through the conical baffle chamber 7. On the one hand, the probability of the material blocking the feed port 5 is relatively reduced, and on the other hand, the agglomerated material can be broken up, thereby improving the subsequent drying efficiency and improving the drying quality.

[0026] A squeezing ball 743 is fixed to the outer side of the lower end of the stirring shaft 74, a cylinder 75 is fixed to the left side of the inner wall of the conical blocking chamber 7, a reciprocating rod 751 is fixed to the output end of the cylinder 75, a top ball 752 is fixed to the lower right end of the reciprocating rod 751, and the squeezing ball 743 contacts the top ball 752 after rotating;

[0027] Through the above steps, when the stirring shaft 74 rotates, the squeezing ball 743 is driven to rotate around its center until the squeezing ball 743 and the top ball 752 contact and squeeze each other. The squeezing ball 743 is forced to pull the spring 1 73, so that the stirring shaft 74 moves upward, driving the stirring blade 741 to move upward, and then the squeezing ball 743 rotates until it is out of contact with the top ball 752. The spring 1 73 generates a reaction force to reset, so that the stirring shaft 74 moves downward, and drives the stirring blade 741 to reset downward, so that the stirring blade 741 first jumps upward and then jumps downward. When a large amount of material is discharged at once and the material blocks the feed port 5, the motor 71 is rotated at this time to make the stirring blade 741 stir the material and jump upward at the same time, which can further break up the material above the feed port 5 and increase the breaking strength, so that the feed port 5 is connected, avoiding continuous blockage of the material, resulting in the stopping of the drying process and affecting the drying efficiency.

[0028] The upper right end of the reciprocating rod 751 is connected to a ball 753, and the ball 753 moves downward and contacts the extrusion ball 743 when the ball 753 rotates.

[0029] Through the above steps, when a lot of materials are discharged at once, the materials block the feed port 5, and there are many materials piled above and it is difficult to stir, the cylinder 75 is running at this time, and the ball 753 is driven to move downward through the reciprocating rod 751, and the top ball 752 moves downward at the same time. At this time, the squeezing ball 743 rotates and contacts with the ball 753, and the ball 753 presses the squeezing ball 743 downward, and the spring 1 73 is deformed by the downward force, and then the squeezing ball 743 rotates until it is out of contact with the ball 753, and the spring 1 73 is reset, so that the stirring blade 741 jumps downward, and the part that is easy to discharge from the bottom is poked out of the feed port 5, thereby playing a role in fast material discharge, further improving the drying efficiency, and no manual unblocking of the feed port 5 is required, which is convenient and efficient.

[0030] A notch 744 is provided below the stirring shaft 74, and a slide bar 745 is slidably connected in the notch 744. A fixing rod 746 is fixed to the front end of the slide bar 745, and a disc 747 is fixed to the upper end of the fixing rod 746. The initial position of the disc 747 is located between the two stirring blades 741.

[0031] A circular ring 748 is fixedly mounted on the rear end of the slide bar 745. The circular ring 748 is sleeved on the outer side of the stirring shaft 74, and a circular arc groove 749 is arranged around the bottom. The circular arc groove 749 fits with the upper end of the sphere 753.

[0032] A limit block is fixed on the inner wall of the stirring shaft 74, a fixed block is fixed on the outer side of the fixed rod 746, and a spring 3 76 is fixedly connected between the limit block and the fixed block.

[0033] The inner upper and lower ends of the two stirring blades 741 are both arc-shaped;

[0034] Through the above steps, when a large amount of material is discharged at once and the material blocks the feed port 5, the positions of the ball 753 and the top ball 752 remain in the initial state, the top of the ball 753 contacts the arc groove 749, and when the stirring shaft 74 rotates, the ball 753 rolls in the arc groove 749, and the ring 748 is pushed upward, and the fixed rod 746 is driven upward by the sliding rod 745. The spring three 76 is stretched and deformed, and the fixed rod 746 drives the disc 747 to be inserted between the two stirring blades 741. The spring two 742 is pulled apart and deformed, and the stirring blade 741 has a wide expansion range, so that the stirring of the material can be further strengthened, the dredging strength is improved, and the feed port 5 can be fully dredged;

[0035] When a large amount of material is discharged at once, the material blocks the feed port 5, and there is a lot of material piled above, making it difficult to stir. At this time, the stirring blade 741 jumps downward. At the same time, due to the downward movement of the sphere 753, the spring three 76 generates a reaction force to reset, thereby driving the fixed rod 746 to move downward through the limit block, and the fixed rod 746 drives the disc 747 to separate from the stirring blade 741. The spring two 742 generates a reaction force to pull the two stirring blades 741 closer to each other, and the stirring range becomes narrower. When the stirring blade 741 jumps downward, the material blocked at the edge of the feed port 5 can be loosened. When the stirring blade 741 stirs, it can further accelerate the falling of the material and speed up the unblocking.

[0036] A material unloading identification module and a torque control module are arranged inside the unloading bin, the material unloading identification module is electrically connected to the torque control module, and the torque control module is electrically connected to the motor 71;

[0037] The material discharge identification module is used to identify the material discharge amount of each material discharge bin, and the torque control module is used to control the torque of the motor 71 according to the single material discharge amount.

[0038] The control mode of the torque control module is: , is the real-time torque of the motor 71, is the maximum torque of the motor 71, is the real-time feeding amount. The maximum material discharge amount, the more material is discharged from the discharge bin, the greater the torque of the motor 71 and the faster the speed;

[0039] When there is a large amount of material being discharged, the torque of the motor 71 is increased, thereby increasing the rotation speed and improving the strength of breaking up the materials. At the same time, when the feed port 5 is blocked, the force of disturbing the materials is increased, thereby increasing the dredging strength and improving the material falling efficiency. When there is a small amount of material being discharged, it is not easy to get blocked at this time, thereby relatively reducing the torque of the motor 71, which can break up the agglomerated materials while reducing energy consumption and costs.
