Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drying equipment, in particular to a drying degree detection device for a drying machine and a detection method thereof. BACKGROUND

[0002] The paddle dryer is a kind of high-efficiency conduction drying equipment widely used in chemical industry, food industry, pharmaceutical industry, environmental protection and other fields. It realizes the continuous drying of materials by evaporating the moisture in the wet materials through the heat conduction of hollow paddles. However, in the actual production process, the drying effect will be affected by different factors, for example, the spacing distance between paddles. Smaller spacing will increase the contact frequency between paddles and materials, improve the heat transfer efficiency, and is suitable for high humidity or heat-sensitive materials (such as food and medicine); while larger spacing will reduce the contact area and reduce the heat transfer efficiency, which is suitable for materials with low heat sensitivity requirements (such as some minerals or chemical products). However, the current market equipment for this test content cannot realize the automatic adjustment of the paddles, and also cannot adjust the size of the drying space according to the overall distribution of the paddles, which may cause useless work area (i.e. when the materials enter the area without paddle distribution, the corresponding drying effect cannot be achieved, which affects the test results).

After drying is completed, it can stop;

[0029] S3, then, after drying, open the adjusting arc cover to expose the feeding port, and make the material flow to the feeding port, finally, fall on the rotating box from the discharging pipe, when not needing detection, adjust the rotating box to rotate and tilt to the side opposite to the collecting funnel, so that the material directly falls into the detection groove, when needing detection, adjust the rotating box to rotate and tilt to the side of the collecting funnel, and adjust the position of the adjusting arc cover and the stopper, so that the material can be discharged from the discharging pipe one by one, then the material falls into the collecting funnel on one side along the rotating box, when the material contacts the stopper, a pushing force is applied to the material and the stopper is opened, in the process, the rotating angle sensor detects the angle of the stopper each time when the stopper is opened, if the opening angle is too large, it indicates that the moisture content in the material is still large, otherwise, it indicates that the drying efficiency of the material is high.

A synchronous member 35 with an "I"-shaped structure is rotatably arranged between the inner walls of the electromagnetic seat 36, and the synchronous member 35 and the electromagnetic seat 36 can be connected as a whole by suction. A worm gear 2 33 and a synchronous wheel 331 that rotate synchronously with it are installed on the synchronous member 35. The synchronous wheel 1 321 and the synchronous wheel 3 331 are located in the same vertical plane and a synchronous belt is also connected between them.

[0070] Among them, the worm 311 can respectively achieve the effect of meshing transmission with the worm wheel 1 32 and the worm wheel 2 33, and no matter whether either the worm wheel 1 32 or the worm wheel 2 33 rotates, the other can simulate the state of meshing with the worm 311 in a translation manner. That is, assuming that the worm wheel 1 32 and the worm wheel 2 33 are both in a state of meshing with the worm 311, that is, the two are symmetrical about the center line of the worm 311, so the initial state of the worm wheel 1 32 (or the worm wheel 2 33) in the accompanying drawings is the state after translation of this symmetrical state, which is equivalent to the worm wheel 1 32 and the worm wheel 2 33 in the accompanying drawings being always symmetrical about the midpoint of the line connecting their centers.

[0071] In addition, contact sensors (not shown in the figure) are embedded on the top and bottom walls of the side grooves. When the contact sensor on one side is triggered by the lifting block 312, the two electromagnetic seats 36 enter the start and stop states respectively under the control of the PLC controller.

[0072] It needs to be further explained that when the lifting frame 31 moves to the highest position, the worm 311 is engaged with the upper worm gear 32 at this time, at this time, the electromagnetic seat 36 in the end shaft 2611 stops working, that is, the end shaft 2611 is rotatably connected with the corresponding synchronous part 35, and the electromagnetic seat 36 in the end shaft 271 is in working state, that is, the end shaft 271 is integrally and synchronously connected with the corresponding synchronous part 35, then through driving the rotary motor three, the worm 311 starts to rotate and output, so that the worm gear 32 rotates, at this time, under the action of the synchronous wheel two 322 and the synchronous wheel four 52, the synchronous shaft 5 drives the screw three 51 to rotate, thereby controlling the position adjustment of the adjusting disc 23, at the same time, the end shaft 271 drives the screw one 27 to rotate, thereby controlling the position adjustment of the connecting part 284, so that the moving plate 28 and the adjusting disc 23 are synchronously adjusted in position, after adjusting appropriately, stop the rotary motor three.

[0073] When the lifting frame 31 moves to the lowest position, the worm 311 is engaged with the lower worm gear 33 at this time, at this time, the electromagnetic seat 36 in the end shaft 271 stops working, that is, the end shaft 271 is rotatably connected with the corresponding synchronous part 35, and the electromagnetic seat 36 in the end shaft 2611 is in working state, that is, the end shaft 2611 is integrally and synchronously connected with the corresponding synchronous part 35, then through starting the rotary motor three, the worm 311 rotates and controls the output of the worm gear 33, thereby driving the rotation of the drive shaft 261, and then synchronously controlling the rotation of the two drive gears 26 on the drive shaft 261, with the rotation of the drive gear 26, the transmission toothed disc 24 on both sides rotates synchronously, and drives the rotation cylinder 25 and the paddle 251 to work together, after drying, stop the rotary motor three.

[0074] Among them, in the rotation process of the worm gear one 32 or the worm gear two 33, the synchronous transmission between the synchronous wheel one 321 and the synchronous wheel three 331 is used, so that when any one of the worm gears rotates, the other worm gear can also rotate, which is equivalent to that even if the worm 311 is only engaged with one of the worm gears for transmission, the other worm gear can also be in the state of being engaged with the worm 311 for transmission, so that when the worm 311 stops and is adjusted vertically to the flat position, it can still ensure the engagement effect when it is in contact with the other worm gear.

[0075] The detection assembly includes a rotating box 4, a moving seat 42, a connecting frame two 43, a collection funnel 44, a cover 442 and a rotation angle sensor 443.

[0076] The two opposite side walls between the inspection tank 12 are fixedly installed with a cross beam arranged along the length direction, one side wall of the cross beam is fixedly installed with two shaft seats two, the two shaft seats two are connected with a guide shaft two, the moving seat 42 is in a "U" type structure and slides between the top wall and the bottom wall of the cross beam, the guide shaft two penetrates through the moving seat 42 and slides in contact with the moving seat 42, and a dovetail bar three is further connected to the surface of the moving seat 42 in contact with the cross beam, the dovetail bar three slides between the inner walls of the cross beam, wherein, an "L" type connecting frame one 234 is further fixedly connected between the top wall of the moving seat 42 and the outer surface of the discharge pipe 232, the middle of the connecting frame one 234 penetrates a guide shaft three in sliding contact therewith, and the guide shaft three is fixed between the two opposite side walls of the base 1.

[0077] The two ends of the rotating box 4 are open and the top is also open, and the two side walls at one end of the rotating box 4 are fixedly installed with a guide block with a triangular cross section, a rotating sleeve is fixed in the middle of the bottom wall of the rotating box 4, and a rotating motor four is fixedly installed on the side wall of the moving seat 42, and the output shaft of the rotating motor four penetrates through the rotating sleeve and is fixedly connected therewith.

[0078] The connecting frame two 43 is in an "L" type structure and is fixed at one end below the bottom wall of the moving seat 42 by means of shaft connection, a collecting funnel 44 penetrates through the inner walls of the other end of the connecting frame two 43 and is fixedly connected therewith, the collecting funnel 44 is located below one side of the position of the two guide blocks, and a fixed ring 441 is fixedly installed on the outer surface of the collecting funnel 44 close to the bottom end, two shaft seats three are further fixedly connected on the fixed ring 441, a rotating block is provided on one end of the cover 442 and is integrated as a whole, a rotating shaft penetrates through the middle of the rotating block and is synchronous therewith, the rotating shaft is rotatably arranged between the side walls of the two shaft seats three by means of shaft connection, one end of the rotating shaft penetrates through one of the shaft seats three, and a rotation angle sensor 443 is installed on the end of the rotating shaft, wherein, two torsional springs (not shown in the figure) are installed on the rotating shaft and are installed between the inner walls of the two shaft seats three, when the torsional springs are not pressed by any force (i.e. in the reset state), the cover 442 is attached to the bottom end of the collecting funnel 44.

[0079] It needs to be further explained that when the adjusting disc 23 is in the adjusting position, the movement of the moving seat 42 is also driven synchronously by the connecting frame one 234, and the moving seat 42, the rotating box 4, and the connecting frame two 43 and the collecting funnel 44 are all connected as a whole, so that the movement of the detection assembly is synchronized with the adjusting disc 23.

[0080] When it is necessary to test the dryness of the material, the size of the feed port 231 is controlled to the minimum diameter by the PLC controller (that is, the shielding process of the feed port 231 is achieved by adjusting the rotation of the arc cover 237). At the same time, the outlet range of the discharge pipe 232 is also controlled to be minimum (that is, the internal channel of the discharge pipe 232 is shielded by the movement of the block 235). This minimum diameter is set according to the particle diameter of the material. Because this embodiment is only aimed at detecting the influence of the change in the spacing of the blades 251 on the dryness of the material, the particles selected in the embodiment are spherical materials with uniform size and consistent quality before drying, so as to avoid uncontrollable factors in the test process. After adjusting to the minimum diameter, the material can only pass through one by one during the inspection.

[0081] During the detection, by starting the rotating motor 4, the rotating box 4 is rotated and tilted to one side of the collecting funnel 44, and the rotation angle is 20 degrees. After the tilt, the top of the collecting funnel 44 is always located below the middle channel of the two guide blocks. As the spherical materials fall one by one, they fall along the discharge pipe 232, fall on the rotating box 4 through the guide plate 212, and fall along the inclined surface into the collecting funnel 44. When the material falls to contact the baffle 442, it applies a force to the baffle 442, thereby opening the baffle 442. At this time, the baffle 442 rotates and the angle sensor 443 records the rotation angle, and the rotation angle is recorded every time a material falls. Finally, the system determines the dryness of the material in the inspection based on the rotation angle (the minimum force required to open the cover 442 downward is generated when a completely dry material exerts a force on it, that is, regardless of the drying effect, even completely dry materials can open the cover 442). If the rotation angle is too small, it means that the drying efficiency is high. Conversely, if the rotation angle is too large, it means that the water content in the material is still very high and the drying efficiency is low.

[0082] After the random inspection is completed, the rotating motor 4 is controlled to drive the rotating box 4 to return to the horizontal direction and then rotate 20 degrees to the other side to stop. At this time, the material falls into the inspection groove 12 from the other side after falling. At the same time, the positions of the arc cover 237 and the stop block 235 are reset and adjusted respectively, so that the outlets of the feed port 231 and the discharge pipe 232 reach the maximum range.

10. The detection method of the dryness detection device for a dryer according to claim 9, characterized in that: The following steps are involved: S1. First, the spacing of the blades (251) and the position of the adjusting disk (23) need to be adjusted. During the adjustment, the worm (311) is controlled to mesh with the worm wheel (32), and then driven by the worm (311), so that the screw (27) and the screw (51) rotate synchronously, so that under the action of the screw transmission, the driving of the movable plate (28) and the connecting block (233) is synchronously realized, and then the movable plate (28) that generates displacement movement drives the other movable movable plates (28) to be adjusted synchronously, so as to adjust the spacing of the blades (251). As the connecting block (233) moves, the discharge pipe (232) also drives the adjusting disk (23) to move and adjust together, and stops after adjusting to the desired position; S2. Then, spherical particles of uniform size and quality are added to the drying chamber from the feeding port. After adding the materials, the sealing cover is tightened, and the connection port is connected to the pipeline of the heating equipment to provide heat to the drying chamber to simulate the heat demand that can be achieved by the actual drying equipment, so that the materials in the drying chamber are continuously dried as the blade (251) rotates. During drying, the worm (311) is controlled to mesh with the worm gear (33), so that the drive shaft (261) drives the drive gear (26) to rotate, and then the rotation of the rotating cylinder (25) is controlled by the transmission gear discs (24) on both sides. After the drying is completed, it can be stopped; S3. Then, after drying is completed, the regulating arc cover (237) is opened to expose the feed port (231), and the material is allowed to flow toward the feed port (231), and finally falls from the discharge pipe (232) onto the rotating box (4). When no detection is required, the rotating box (4) is adjusted to rotate and tilt toward the opposite direction of the collecting funnel (44), so that the material falls directly into the inspection slot (12). When detection is required, the rotating box (4) is adjusted to rotate and tilt toward one side of the collecting funnel (44), and the regulating arc is adjusted at the same time. The positions of the cover (237) and the block (235) allow the materials to be discharged from the discharge pipe (232) one by one, and then the materials fall into the collecting funnel (44) on one side along the rotating box (4). When the materials come into contact with the blocking cover (442), a thrust is applied to it and it is opened. During this process, the angle sensor (443) detects the angle of each opening of the blocking cover (442). If the opening angle is too large, it means that the moisture content in the material is still very high. Otherwise, it means that the drying efficiency of the material is high.
