It has the characteristics of high heat transfer coefficient, large heat transfer area, short drying time, etc. Some materials are prevented from agglomerating due to moisture for a long time. When they are put into the dryer, they often need to be beaten to break up the materials, which greatly affects the work efficiency. Moreover, the breaking up is not comprehensive, and a small amount of agglomerated materials will enter the dryer, resulting in the inability to fully dry the agglomerated materials, affecting the drying quality. This phenomenon has become a problem that people in this field need to solve urgently. Summary of the invention

[0007] The present invention further illustrates that a threaded block is fixedly installed on the inner wall of the feed chamber, and a threaded hole is arranged in the middle of the threaded block, a telescopic joint is fixed on the upper end of the connecting rod, a threaded rod is fixed on the upper end of the telescopic joint, and the threaded rod is threadedly connected in the threaded hole; a push-pull ball is fixed on the left side of the upper end of the threaded rod, and a squeezing ball is fixedly connected at the bottom of the elastic telescopic rod, and the push-pull ball contacts the squeezing ball after rotation.

[0008] The present invention further states that the diameter of the push-pull ball is twice the diameter of the squeeze ball.

[0009] The present invention further illustrates that the intelligent breaking up system includes a material identification module and a control module, the material identification module is electrically connected to the control module, the control module is electrically connected to the motor and the cylinder, the material identification module is used to identify the amount of material put into the dryer at a single time, and the control module is used to control the speed of the motor according to the amount of material put into the dryer at a single time, and control the stroke of the cylinder.

[0010] The present invention further illustrates that the speed control method of the motor is: , is the real-time speed of the motor, is the maximum speed of the motor, is the amount of material put into the dryer at one time, is the maximum amount of material that can be put into the dryer at one time; the stroke control method of the cylinder is: , is the real-time stroke of the cylinder, The maximum stroke of the cylinder.

While the stirring rod is initially breaking up the materials, the breaking blades quickly rotate in the opposite direction and reset, thereby further breaking up the materials. This step can fully break up the materials, further strengthen the breaking strength of the materials, and fully prevent the agglomerated materials from entering the dryer. The operation of the cylinder increases the force on the elastic spring, and at this time, the meshing between the fan teeth and the top of the slider slips, thereby shortening the travel of the slider to the rear, and reducing the travel of the push rod, thereby reducing the deformation strength of the volute spring. Since the breaking strength of the stirring rod is high, the deformation strength of the volute spring is reduced at this time, so that its reaction force is reduced, and the force of the breaking blade when resetting is reduced, which can further break up the materials and avoid the damage to the surface quality of the materials caused by excessive breaking strength, and prevent the materials from being broken up and affecting the quality of the materials. By swinging the stirring rod left and right through the elastic telescopic rod, the material breaking strength can be further improved, the material can be fully broken up, and the feeding cavity can be further unblocked.

DETAILED DESCRIPTION

[0013] 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.

[0014] See also Figure 1-8 The present invention provides a technical solution: a vertical circulating airflow dryer with a caking logistics breaking structure, comprising a drying chamber 1, a circulating pump 4 and an intelligent breaking system, a discharge pipe 2 is connected to the bottom of the drying chamber 1, a feed chamber 3 is connected to the top of the drying chamber 1, and the top of the feed chamber 3 is open; The circulation pump 4 is connected to the left and right pipes of the drying chamber 1 respectively. A material scattering mechanism is arranged inside the feeding chamber 3. The material scattering mechanism includes a motor 31, an elastic telescopic rod 311, a stirring rod 312, a sliding rod 313 and a sleeve 314. The motor 31 is fixedly installed on the left side of the feeding chamber 3. The elastic telescopic rod 311 is fixedly connected to the output end of the motor 31. The stirring rod 312 is fixedly installed on the right end of the elastic telescopic rod 311. The sleeve 314 bearing is installed on the right side of the inner wall of the feeding chamber 3. Two limit blocks are arranged on the outer side of the sliding rod 313, and are slidably connected in the sleeve 314. The material is put into the dryer through the feed chamber 3, and the circulating pump 4 is running at the same time, and the hot air is injected into the drying chamber 1 through the pipeline, and then the air is extracted and heated through another pipeline, and the circulating hot air dries the material. After drying, the material is discharged from the dryer through the discharge pipe 2. When the material is put into the feed chamber 3, the motor 31 is running, and the stirring rod 312 is driven to rotate through the elastic telescopic rod 311, and the stirring rod 312 drives the sliding rod 313 to rotate, and the sliding rod 313 drives the sleeve 314 to rotate through the limit block. When the stirring rod 312 rotates, the agglomerated material in the material can be squeezed and broken up, which is convenient for subsequent improvement of drying efficiency and drying quality. The material breaking process is automated, convenient and efficient, and the material breaking effect is good.

[0015] The outer side of the sleeve 314 is fixedly mounted with a sector tooth 315, the inner wall of the feed chamber 3 is fixedly mounted with a slide rail 32, the inner wall of the slide rail 32 is slidably connected with a slider 321, and a plurality of tooth blocks are arranged above the slider 321 and mesh with the sector tooth 315; A striking rod 322 is fixed to the bottom front side of the slider 321, a cylinder 323 is fixed to the rear side of the inner wall of the slide rail 32, a pressing plate 324 is fixedly connected to the output end of the cylinder 323, and an elastic spring 325 is fixedly connected between the pressing plate 324 and the slider 321; When the sleeve 314 rotates, the fan teeth 315 are driven to rotate. The fan teeth 315 drive the slider 321 to slide backward along the inner wall of the slide rail 32 through engagement. The elastic spring 325 is squeezed and deformed. At the same time, the cylinder 323 runs, driving the pressure plate 324 to move forward, further squeezing the elastic spring 325 to increase its deformation strength. After the slider 321 moves backward, it drives the front end of the impact rod 322 to disengage from the inner wall of the feed chamber 3. Then the fan teeth 315 rotate to disengage from the upper part of the slider 321. The elastic spring 325 generates a reaction force to push the slider 321 to move forward and reset quickly, so that the impact rod 322 moves forward quickly and hits the inner wall of the feed chamber 3, which can fully shake off the material attached to the inner wall, ensure that the material can quickly enter the dryer for drying, and can effectively prevent the material from blocking the feed chamber 3, thereby playing a dredging role.

[0016] The inner wall bearing of the feed chamber 3 is connected with a scattering blade 33, and a volute spring is arranged in the bearing. The upper end of the scattering blade 33 is fixedly connected with a connecting rod 331, and a push rod 332 is fixed to the right side of the connecting rod 331. A ball 326 is fixed to the rear side of the bottom of the slider 321, and the ball 326 contacts the push rod 332 after moving; Through the above steps, when the slider 321 moves to the rear side, it drives the ball 326 to move to the rear side, and the ball 326 pushes the push rod 332. The push rod 332 drives the breaking blade 33 to rotate through the connecting rod 331. The volute spring in the bearing is deformed by force, and then the reaction force generated by the elastic spring 325 causes the slider 321 to quickly reset. The reaction force generated by the volute spring causes the breaking blade 33 to quickly rotate in the opposite direction and reset, thereby further breaking up the material. This step can fully break up the material, further strengthen the breaking strength of the material, and fully prevent the agglomerated material from entering the dryer. And through the operation of the cylinder 323, the force on the elastic spring 325 increases. At this time, the engagement between the fan tooth 315 and the upper part of the slider 321 slips, thereby shortening the stroke of the slider 321 moving to the rear side, and reducing the stroke of the push rod 332, thereby reducing the deformation strength of the volute spring. Since the stirring rod 312 has a high breaking strength, the deformation strength of the volute spring is reduced at this time, so that its reaction force is reduced, and the force of the breaking leaf 33 when resetting is reduced, which can further break up the material while avoiding damage to the surface quality of the material due to excessive breaking strength, and prevent the material from being broken and affecting the quality of the material.

[0017] A threaded block 34 is fixedly mounted on the inner wall of the feed chamber 3, and a threaded hole is arranged in the middle of the threaded block 34. A telescopic joint 333 is fixed to the upper end of the connecting rod 331, and a threaded rod 334 is fixed to the upper end of the telescopic joint 333. The threaded rod 334 is threadedly connected in the threaded hole. A push-pull ball 335 is fixed to the left side of the upper end of the threaded rod 334 , and a squeeze ball 35 is fixedly connected to the lower side of the elastic telescopic rod 311 . The push-pull ball 335 contacts the squeeze ball 35 after rotating.

[0018] The diameter of the push-pull ball 335 is twice the diameter of the squeeze ball 35; When the connecting rod 331 rotates, the threaded rod 334 is driven to rotate through the telescopic joint 333, so that the threaded rod 334 rotates in the threaded hole of the threaded block 34 and moves upward. At the same time, the telescopic joint 333 is stretched, thereby driving the push-pull ball 335 to rotate around the center and move upward to squeeze the extrusion ball 35. The extrusion ball 35 is forced to shorten the elastic telescopic rod 311 to the left, thereby driving the stirring rod 312 to move to the left. The sliding rod 313 slides to the left in the sleeve 314 through two limit blocks, and then the push-pull ball 335 rotates until it is out of contact with the extrusion ball 35. The elastic telescopic rod 311 is elastically reset, so that the stirring rod 312 swings left and right, which can further enhance the material breaking strength, fully break up the material, and further dredge the feeding chamber 3.

[0019] The intelligent breaking up system includes a material identification module and a control module. The material identification module is electrically connected to the control module. The control module is electrically connected to the motor 31 and the cylinder 323. The material identification module is used to identify the amount of material put into the dryer at a single time. The control module is used to control the speed of the motor 31 according to the amount of material put into the dryer at a single time, and control the stroke of the cylinder 323.

[0020] The speed control method of the motor 31 is: , is the real-time speed of the motor 31, is the maximum speed of the motor 31, is the amount of material put into the dryer at one time, The maximum amount of material that can be put into the dryer at one time; The stroke control method of cylinder 323 is: , is the real-time stroke of cylinder 323, is the maximum stroke of cylinder 323; The more material is put into the dryer at a time, the higher the speed of the motor 31 is, and the greater the stroke of the cylinder 323 is; As the amount of material is small, the internal lumps will be relatively small. At this time, the speed of the motor 31 is low, and the stroke of the cylinder 323 is small, and the breaking strength of the stirring rod 312 is low. At this time, since the force exerted on the elastic spring 325 is small, the stroke of the push rod 332 is increased, and the breaking strength of the breaking leaf 33 is increased. At the same time, the rotation amplitude of the threaded rod 334 is large, and the up and down movement stroke is large. When the push-pull ball 335 rotates around the center, the extrusion surface with the extrusion ball 35 is gradually reduced, the stroke of the elastic telescopic rod 311 shortened to the left is reduced, and the shaking amplitude of the stirring rod 312 is small, which can ensure that the materials are fully broken up. The material can be dispersed, and energy consumption can be reduced, and the wear between structures can be reduced, and the service life can be increased. On the contrary, the speed of the motor 31 is increased, and the stroke of the cylinder 323 is increased. The breaking strength of the stirring rod 312 is large, and the breaking strength of the breaking blade 33 is reduced, so as to avoid that the material is broken up excessively and damaged and affect the quality. At the same time, when the push-pull ball 335 rotates around the center, it basically remains stable with the extrusion surface of the extrusion ball 35, so that the stroke of the elastic telescopic rod 311 to the left is increased. At this time, by increasing the left and right shaking amplitude of the stirring rod 312, the material can be fully broken up and the strength of the material breaking can be improved.
