Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a drying machine. Background Art

[0002] A drying machine is an industrial equipment used to dry various materials. It uses hot air or other heat sources to expose the materials to a high temperature environment to remove moisture in order to achieve an ideal drying effect. A drying machine is usually composed of a feeding device, a heating device, a drying chamber, an exhaust system, and a discharging device. Different types of drying machines can be suitable for materials of different types, shapes, and specifications. Materials are often piled up and dried in pursuit of efficiency.

[0003] A Chinese patent discloses a plastic drying machine (authorization announcement number CN202264326U), which includes an air intake pipe and a hopper connected to the air intake pipe, and the plastic drying machine also includes a dust-proof structure disposed at the air inlet end of the air intake pipe. Since the dust-proof structure is disposed at the air inlet end of the air intake pipe, the defect that the unfiltered air with dust, powder and other impurities in the air directly enters the hopper and causes the clean plastic raw materials to be contaminated is effectively overcome, and the drying effect of the plastic drying machine is improved while effectively reducing the miscellaneous black spots of the plastic products and improving the yield rate of the plastic products, and the service life of the plastic drying machine is extended.

[0004] This patented technology prevents the contamination of materials by air introduced from the outside when in use, but it still has some shortcomings when in use. Materials piled up together may lead to reduced circulation of drying air, causing local temperatures to be too high or too low, resulting in uneven drying of materials, thereby reducing heat conduction efficiency, and further reducing drying speed and production efficiency. Therefore, those skilled in the art provide a drying machine to solve the problems raised in the above background technology. Utility Model Content

[0007] The drying structure includes a mounting frame located inside the machine body, support nets are arranged at both ends of the mounting frame, mounting shafts are arranged at both ends of the mounting frame and are rotatably installed inside the two ends of the machine body, a motor with an output end connected to the mounting shaft is arranged on one side of the machine body, a feed pipe is installed through one end of the mounting frame, and a hot air blower is installed inside the machine body at the output end;

[0008] as well as;

[0009] The material guiding structure includes a sealing ring embedded in the lower end of the machine body, a material discharge pipe slidably inserted into the sealing ring, a top rod suspended at the opening of the material discharge pipe, a material discharge pipe installed at the upper and lower ends of the mounting frame, a valve block and a support ring located inside the material discharge pipe, symmetrically distributed support blocks are arranged above the valve block, a spring is connected between the support block and the valve block, a material box is located at the upper end of the machine body, and hydraulic rods are located on both sides of the lower side of the machine body.

[0010] Furthermore, a mounting frame is provided at the lower end of the machine body, a dehumidification valve is installed through the upper end of the machine body, visual windows are provided at both the front and rear ends of the machine body, and relatively distributed guide plates are provided at the inner walls at both the upper and lower ends of the mounting frame;

[0011] Specifically, the mounting frame supports the lower end of the machine body, and the moisture generated by drying the materials is discharged through the dehumidification valve, so that the situation inside the machine body can be observed visually.

[0012] Furthermore, a feeding pipe is provided at the lower end of the material box, and a control valve is provided inside the feeding pipe and the feeding pipe;

[0013] Specifically, the material box conveys the material to the feed pipe through the feed pipe, and then conveys the material to the inside of the installation frame, and the control valve opens and closes the feed pipe and the feed pipe.

[0014] Furthermore, a bracket is sleeved on the outer wall of the hydraulic rod, a mounting ring connected to the telescopic end of the hydraulic rod is sleeved on the outer wall of the lower end of the feed tube, and a collection box is arranged below the feed tube;

[0015] Specifically, the bracket supports and fixes the hydraulic rod, and transmits the conveying power of the hydraulic rod to the discharge pipe through the mounting ring, and the collecting box receives the material output by the discharge pipe.

[0016] Furthermore, the outer wall of the mandrel is provided with support rods distributed in a ring array and connected to the inner wall of the feed pipe, and the upper end of the feed pipe is provided with a hopper;

[0017] Specifically, the support rod supports the push rod, and at the same time prevents the push rod from closing the down pipe and affecting the discharge of the down pipe. The hopper enlarges the receiving port diameter of the down pipe when receiving the material.

[0018] Furthermore, a sliding sleeve is embedded and installed inside the support block, and a guide rod is inserted inside the spring, the upper end of which is slidably inserted inside the sliding sleeve and the lower end of which is connected to the valve block;

[0019] Specifically, the sliding sleeve provides sliding support for the guide rod, and supports the valve block through the spring. When the spring is extended or retracted, it is limited by the guide rod to avoid deviation to the outside.

[0020] Compared with the prior art, the utility model has the following beneficial effects: support nets are arranged at the front and rear ends of the installation frame, and the hot air flow delivered by the hot air blower acts on the material to be dried on the inner wall of the installation frame through the support net, and the installation frame can rotate during drying, and when rotating, the material is ensured to be in a flowing state, which helps to avoid uneven drying caused by accumulation, and the flowing material is more easily heated, and the hot air can more fully enter the gap between the materials, thereby improving the efficiency of the entire drying process;

[0021] At the same time, during the unloading process, the valve block is lifted up by the push rod to open the discharge port, and then the material is discharged. During the feeding, discharging and drying process, the installation frame has no direct contact with the outside world, reducing the possibility of internal contamination and ensuring the cleanliness of the inside of the drying equipment.

[0032] See also Figure 1 , Figure 2 As shown, a drying machine,

[0033] The device comprises a body 100,

[0034] The drying structure 200 includes a mounting frame 203 located inside the machine body 100, support nets 205 are provided at both ends of the mounting frame 203, mounting shafts 204 are located at both ends of the mounting frame 203 and are rotatably installed inside both ends of the machine body 100, a motor 201 whose output end is connected to the mounting shaft 204 is provided on one side of the machine body 100, a feed pipe 206 is installed through one end of the mounting frame 203, and the output end is installed through a hot air blower 202 installed inside the machine body 100;

[0035] The lower end of the body 100 is provided with a mounting frame 101, the upper end of the body 100 is provided with a dehumidification valve 103, the front and rear ends of the body 100 are provided with visual windows 102, and the inner walls of the upper and lower ends of the mounting frame 203 are provided with relatively distributed guide plates 207;

[0037] In this embodiment, because the installation frame 203 is supported by the installation shaft 204 for rotation and is continuously flipped under the drive of the motor 201, the material inside will flow during the rotation, and the hot air flow delivered by the hot air blower 202 acts on the material inside the installation frame 203 through the support net 205, thereby avoiding the accumulation and adhesion of the material, and increasing the fluidity of the material. When the material is in a state of continuous flow, it is not easy to cause problems such as agglomeration and adhesion, thereby avoiding uneven drying due to accumulation. By uniform drying and improving efficiency, the energy consumption in the drying process can be reduced, thereby achieving energy-saving effects.

[0039] as well as;

[0040] The material guiding structure 300 includes a sealing ring 317 embedded in the lower end of the machine body 100, a material discharge pipe 302 slidably inserted in the sealing ring 317, a top rod 309 suspended at the opening of the material discharge pipe 302, a material discharge pipe 308 penetrating and installed at the upper and lower ends of the installation frame 203, a valve block 314 and a support ring 315 located inside the material discharge pipe 308, symmetrically distributed support blocks 312 are arranged above the valve block 314, a spring 316 is connected between the support block 312 and the valve block 314, a material box 306 located at the upper end of the machine body 100, and hydraulic rods 301 located on both sides of the lower side of the machine body 100;

[0041] The outer wall of the hydraulic rod 301 is sleeved with a bracket 304, the outer wall of the lower end of the discharge pipe 302 is sleeved with a mounting ring 303 connected to the telescopic end of the hydraulic rod 301, and a collection box 305 is provided below the discharge pipe 302;

[0042] The outer wall of the top rod 309 is provided with support rods 311 distributed in a circular array and connected to the inner wall of the feed pipe 206, and the upper end of the feed pipe 206 is provided with a hopper 310;

[0043] A sliding sleeve 318 is embedded in the support block 312, and a guide rod 313 is inserted into the spring 316, the upper end of which is slidably inserted into the sliding sleeve 318 and the lower end of which is connected to the valve block 314;

[0044] In this embodiment, after the material is dried, the hydraulic rod 301 drives the discharge pipe 302 to rise and drive the push rod 309 to lift the lower end of the valve block 314, so that the material inside the installation frame 203 is discharged through the discharge pipe 308, and the feed pipe 206 effectively receives the material. When the material box 306 outputs the material, it is transported to the feed pipe 206 through the feed pipe 307. The material feeding, drying and unloading do not require the drying equipment to be turned on, which avoids continuous energy consumption, reduces energy costs, reduces daily wear and tear on equipment, reduces personnel operations around the drying equipment, and reduces safety risks for operators.

[0045] Working principle: the control valve 208 inside the feed pipe 307 and the feed pipe 206 is opened, the material inside the material box 306 is transported to the feed pipe 206 through the feed pipe 307, and then enters the installation frame 203. After the material transportation is completed, the control valve 208 controls the feed pipe 307 and the feed pipe 206 to close, and the hot air blower 202 transports the dry hot air flow into the body 100. The hot air flow enters the installation frame 203 through the pores of the support net 205. During this process, the motor 201 operates to drive the installation shaft 204 to rotate, and the installation shaft 204 drives the installation frame 203 to rotate, and the material inside the installation frame 203 flows and fully contacts with the hot air flow;

[0046] After the material is dried, the discharge pipe 308 corresponds to the feed pipe 302, and the hydraulic rod 301 drives the mounting ring 303 to move longitudinally, lifting the feed pipe 302. The collecting box 305 is located at the lower end of the feed pipe 302, and the push rod 309 enters the discharge pipe 308 to apply extrusion force to the valve block 314. The hopper 310 is sleeved on the outside of the discharge pipe 308. The valve block 314 is forced to squeeze the spring 316, and the spring 316 is forced to shrink and is guided by the guide rod 313 to move longitudinally. The valve block 314 is opened and installed. The material inside the frame 203 flows to the discharge pipe 308 through the guide plate 207, and the discharge pipe 308 outputs the material into the down pipe 302. The collecting box 305 receives the material output by the down pipe 302, and then the hydraulic rod 301 drives the mounting ring 303 to descend, and the mounting ring 303 drives the down pipe 302 to reset, and the push rod 309 stops squeezing the valve block 314. After the spring 316 stops being stressed, it pushes the valve block 314 to descend, and closes the opening of the support ring 315, thereby closing the mounting frame 203.
