[0002] In the material processing of industries such as food, chemical, and salt, drying and screening are key processes to ensure product quality. The material must first be dried to remove moisture to prevent clumping, and then screened to separate materials of different particle sizes to meet subsequent production needs.

[0003] Existing equipment lacks an effective condition monitoring and linkage control mechanism, making it unable to detect abnormalities such as material residue and blockage in a timely manner. Frequent manual inspections and adjustments are required, increasing operating costs. This phenomenon has become a problem that urgently needs to be solved by professionals in this field. Summary of the Invention

[0004] The purpose of this invention is to provide a dryer with product screening function for existing devices, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a dryer with product screening function, including a tank and a controller disposed outside the tank. A fixed frame is fixedly connected to the top of the tank, and a feed inlet is opened on the top of the fixed frame. A motor is installed on one side of the feed inlet, and a spiral shaft is connected to the output end of the motor. A first heater is disposed outside the fixed frame, and a discharge pipe is disposed below the fixed frame. One end of a pulley assembly is connected to the output end of the motor, and a connecting rod is connected to the other end of the pulley assembly. A striking component is disposed outside the connecting rod.

[0006] The present invention further illustrates that the striking assembly includes a first striking block fixedly connected to a connecting rod, a first support rod fixedly connected to one side of the first striking block, a second striking block fixedly connected to the other side of the first support rod, a second support rod fixedly connected to one end of the second striking block, and one side of the second support rod connected to the inner wall of the tank via a bearing.

[0007] The present invention further illustrates that a fixing rod is fixedly connected between the first striking block and the second striking block, and a brush is provided on the outside of the fixing rod.

[0008] The present invention further illustrates that the inner walls of the two sets of tanks are provided with two sets of sliding grooves, and sliding rods are fixedly connected inside the two sets of sliding grooves. A return spring is sleeved on the outside of the sliding rod, and a slider is fixedly connected to the top of the return spring. The slider is sleeved on the outside of the sliding rod, and a screening plate is fixedly connected to one side of the slider.

[0009] The present invention further illustrates that a side discharge outlet is provided on one side of the tank body, and a sealing plate is slidably connected inside the side discharge outlet.

[0010] The present invention further illustrates that a connecting block is fixedly connected to the side of the tank near the sealing plate, a positioning pin is slidably connected inside the connecting block, the bottom end of the positioning pin contacts the sealing plate, a material collection frame is fixedly connected to one side of the tank, and a discharge channel is provided at the bottom of the tank.

[0011] The present invention further illustrates that a connecting sleeve is provided on the opposite side of the first support rod and the second support rod, and a support frame is connected between the two sets of connecting sleeves by a bearing, and a cavity is opened inside the second support rod.

[0012] The present invention further illustrates that an air pump is installed on the top of the tank, and the air outlet of the air pump is connected to a connecting pipe.

[0014] The present invention further illustrates that a vision sensor is provided on one side of the screening plate.

[0015] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: In this invention, after material is fed into a fixed frame through the inlet, the controller starts the motor and the first heater. The motor drives the screw shaft to push the material, while the first heater simultaneously heats and pre-dries it. The material falls into the tank through the discharge pipe onto the screening plate. The motor drives the connecting rod to rotate via a pulley assembly, causing the striking component to periodically strike the screening plate. Combined with the sliding rod, return spring, and slider, this causes the screening plate to vibrate at high frequency, classifying the material. Fine material falls to the bottom of the tank, while coarse material remains. Simultaneously, a brush cleans the screening plate to prevent clogging, and an air pump heats air through a second heater before spraying it out from a universal nozzle for secondary drying. A visual sensor monitors the thickness of the residual material, and the controller adjusts the motor speed, material input rate, and hot airflow parameters accordingly. Finally, fine material is discharged from the discharge channel, and coarse material is discharged through the side discharge outlet. Attached Figure Description

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-8 The present invention provides a technical solution including a tank body 1 and a controller installed outside the tank body 1. A fixed frame 2 is fixedly connected to the top of the tank body 1. A feed inlet 3 is opened on the top of the fixed frame 2. A motor 4 is installed on one side of the feed inlet 3. A screw shaft 5 is connected to the output end of the motor 4. A first heater 6 is installed outside the fixed frame 2. A discharge pipe 7 is installed below the fixed frame 2. Material is fed into fixed frame 2 through feed inlet 3. The controller starts motor 4 and first heater 6. Motor 4 drives screw shaft 5 to rotate. Screw shaft 5 pushes material along the inside of fixed frame 2. At the same time, first heater 6 heats fixed frame 2 to achieve synchronous drying of material during conveying. The dried material falls into screen plate 15 inside tank 1 through discharge pipe 7.

[0020] The output end of the motor 4 is connected to one end of the pulley group 8, and the other end of the pulley group 8 is connected to the connecting rod 9. A striking component 10 is provided on the outside of the connecting rod 9. The striking component 10 includes a first striking block 1001 fixedly connected to the connecting rod 9. A first support rod 1002 is fixedly connected to one side of the first striking block 1001. A second striking block 1003 is fixedly connected to the other side of the first support rod 1002. A second support rod 1004 is fixedly connected to one end of the second striking block 1003. One side of the second support rod 1004 is connected to the inner wall of the tank 1 through a bearing. A fixing rod 1005 is fixedly connected between the first striking block 1001 and the second striking block 1003. A brush 1006 is provided on the outside of the fixing rod 1005. The controller starts the motor 4, and the output of the motor 4 drives the connecting rod 9 to rotate through the pulley group 8. The connecting rod 9 drives the first striking block 1001 in the striking assembly 10 to rotate synchronously. The first striking block 1001 can drive the first support rod 1002 and the second striking block 1003 to rotate synchronously. The second striking block 1003 drives the second support rod 1004 to rotate with the inner wall of the tank 1 through the axis. When the first striking block 1001 and the second striking block 1003 rotate synchronously, they can drive the fixed rod 1005 and the brush 1006 to rotate synchronously. When the brush 1006 contacts the screening plate 15, it can clean and scrape the material on the top of the screening plate 15.

[0021] Two sets of sliding grooves 11 are provided on the inner wall of the two sets of tanks 1. Sliding rods 12 are fixedly connected inside the two sets of sliding grooves 11. A return spring 13 is sleeved on the outside of the sliding rod 12. A slider 14 is fixedly connected to the top of the return spring 13. The slider 14 is sleeved on the outside of the sliding rod 12. A screening plate 15 is fixedly connected to one side of the slider 14. The output end of motor 4 drives the connecting rod 9 to rotate through the pulley group 8. The first striking block 1001 and the second striking block 1003 rotate synchronously and can periodically strike both sides of the screening plate 15. The screening plate 15 is connected to the sliding rod 12 on the inner wall of the tank 1 through the slider 14, and the bottom of the slider 14 is provided with a return spring 13. When the first striking block 1001 and the second striking block 1003 strike the screening plate 15, the screening plate 15 is pressed down and slides and compresses the return spring 13. After the striking ends, the return spring 13 rebounds and drives the screening plate 15 to return to its original position, forming high-frequency vibration, which can then vibrate and screen the material.

[0022] A side discharge outlet 16 is provided on one side of the tank body 1. A sealing plate 17 is slidably connected inside the side discharge outlet 16. A connecting block 18 is fixedly connected to the side of the tank body 1 near the sealing plate 17. A positioning pin 19 is slidably connected inside the connecting block 18. The bottom end of the positioning pin 19 contacts the sealing plate 17. A material collection frame 20 is fixedly connected to one side of the tank body 1. A discharge channel 21 is provided at the bottom of the tank body 1. During vibration, materials with a particle size smaller than the mesh size of the screening plate 15 fall through the screening plate 15 into the bottom of the tank 1 and are discharged through the discharge channel 21. Materials with a larger particle size remain on the screening plate 15. Pulling the positioning pin 19 upwards allows the material to be discharged from the side discharge outlet 16 to the collection frame 20 by pulling the sealing plate 17. The position of the sealing plate 17 can be fixed by inserting the positioning pin 19 into the connecting block 18 to ensure the sealing during the vibrating screen discharge.

[0023] A connecting sleeve 22 is provided on the opposite side of the first support rod 1002 and the second support rod 1004. A support frame 23 is connected between the two sets of connecting sleeves 22 by a bearing. A cavity 24 is opened inside the second support rod 1004. An air pump 25 is installed on the top of the tank 1. A connecting pipe 26 is connected to the air outlet of the air pump 25. A second heater 27 is provided on the outside of the connecting pipe 26. Multiple sets of universal nozzles 28 are provided at the bottom of the connecting pipe 26. A vision sensor 29 is provided on one side of the screening plate 15. After the air pump 25 at the top of the tank 1 is started, it draws in ambient air from the outside and delivers it to the second heater 27 through the connecting pipe 26 for heating. The heated airflow is finally sprayed out through the universal nozzle 28, which can perform secondary drying on the material of the screening plate 15. The vision sensor 29 can monitor the material on the top of the screening plate 15 and thus monitor the thickness of the residual material.

[0024] Working principle: First, after the material is fed into the fixed frame 2 through the feed inlet 3, the controller starts the motor 4 and the first heater 6. The motor 4 drives the spiral shaft 5 to rotate and push the material. The first heater 6 simultaneously heats the fixed frame 2, completing the pre-drying of the material during the conveying process. The dried material falls onto the screening plate 15 inside the tank 1 through the discharge pipe 7. At the same time, the motor 4 drives the connecting rod 9 to rotate through the pulley group 8, which in turn drives the entire striking assembly 10 to rotate. The first striking block 1001 and the second striking block 1003 periodically strike both sides of the screening plate 15. With the elastic support of the slide rod 12, the return spring 13 and the slider 14, the screening plate 15 forms a high-frequency up and down vibration, realizing the material... According to particle size classification, fine materials pass through the mesh and fall to the bottom of the tank, while coarse materials remain on the screening plate 15. Simultaneously, the brush 1006 on the outside of the fixing rod 1005 rotates synchronously with the assembly, cleaning the material surface of the screening plate 15 to prevent mesh blockage. Meanwhile, the air pump 25 at the top of the tank 1 starts, drawing in ambient temperature air which is then transported through the connecting pipe 26 to the second heater 27 for heating. This heated air is then sprayed out through multiple sets of universal nozzles 28 to perform secondary drying on the material on the screening plate 15, further reducing its moisture content. The vision sensor 29 monitors the thickness of the residual material on the screening plate 15 in real time. The controller sets the standard residual parameter value of the screening plate 15 to C, and the actual monitored value is C1. If the residual material monitored by the vision sensor 29... If the residue value C1 > C, it can be determined that the screening frequency is low and the material input is large. In this case, the speed of motor 4 can be increased and the material input can be reduced. The first striking block 1001 and the second striking block 1003 can perform high-frequency reciprocating striking on the screening plate 15, causing the residual material to fall quickly. If the residue value monitored by the vision sensor 29 is still C1 > C after adjusting the speed of motor 4, it can be determined that there is wet material clogging the mesh of the screening plate 15. At this time, the heating power of the second heater 27 is increased, the temperature of the hot air jet from the universal nozzle 28 is increased, and the wind speed is increased. The high-temperature and high-speed air jet strengthens the rapid drying of the material on the surface of the screening plate 15, reducing the residue. The material viscosity is reduced to reduce mesh clogging. At the same time, the brush 1006 rotates at high frequency with the striking component 10, and the airflow impacts to deeply clean the surface and mesh of the screening plate 15. When the residual value monitored by the vision sensor 29 is C1 < C, the speed of the motor 4, the air output of the air pump 25 and the heating temperature of the second heater 27 can be restored to the initial operating state. Then, the fine material is discharged through the discharge channel 21 at the bottom of the tank 1. Pulling up the positioning pin 19 and pulling out the sealing plate 17 can discharge the coarse material on the screening plate 15 from the side discharge outlet 16 to the collection frame 20 for secondary processing. The sealing plate 17 is fixed by the positioning pin 19 to ensure the sealing of the vibrating screening process.
