Description

Technical Field

[0001] The invention relates to the technical field of disc drying equipment, in particular to an improved high-efficiency disc drying equipment. Background Art

[0002] Calcium hydrogen phosphate is a white monoclinic crystalline powder, odorless and tasteless, usually existing in the form of dihydrate, stable in the air, and begins to lose crystal water and become anhydrous when heated to 75°C. It becomes pyrophosphate at high temperature, and is easily soluble in dilute hydrochloric acid, dilute nitric acid, and acetic acid, slightly soluble in water, and insoluble in ethanol. Calcium hydrogen phosphate powder needs to be dried during the production process. The drying is completed by a drying device. After the calcium hydrogen phosphate enters the drying plate in the drying equipment, the heater will heat the gas and then cooperate with the air pump to fill the high-temperature gas into the drying equipment. The calcium hydrogen phosphate in the drying equipment is dried under the action of hot air.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figures 1 to 8 As shown, the present invention includes the following embodiments: Embodiment 1:

[0031] An improved high-efficiency disc drying device comprises a drying cylinder 1 and a drying disc 2 inside the drying cylinder 1; the apertures of the drying holes 21 of the drying discs 2 decrease from top to bottom; a feed pipe 11 is arranged on the top of the drying cylinder 1; a plurality of discharge pipes 12 are arranged on the outer wall of the drying cylinder 1, which are the same in number as the drying discs 2; the discharge pipes 12 are flush with the upper surfaces of the corresponding drying discs 2; control valves are arranged in the feed pipe 11 and the discharge pipe 12; the bottom of the drying cylinder 1 is supported by a bottom plate 3 and a support leg 31; a reflux cavity is formed between the bottommost drying disc 2 and the inner bottom wall of the drying cylinder 1 22; the material is intercepted by the drying hole 21 on the bottom drying plate 2; the top of the drying cylinder 1 is connected to the air pump 4; the air pump 4 is connected to the reflux chamber 22 through the reflux pipe 41; the reflux pipe 41 is connected in series with the heater 42 and the dewatering component 43; the center of the drying cylinder 1 passes through the main shaft 5 from top to bottom and is rotatably sealed; the main shaft 5 is rotatably sealed with the drying plate 2; the main shaft 5 is fixedly connected to the output shaft of the motor 51 at the lower end; the motor 51 is fixedly connected to the bottom plate 3; the corresponding upper surface of the drying plate 2 is contacted with a stirring member 23; the stirring member 23 is fixedly connected to the outer wall of the main shaft 5.

[0032] In this embodiment, the stirring member 23 is plate-shaped; the stirring member 23 contacts the outer wall of the main shaft 5; the stirring member 23 contacts the inner wall of the drying cylinder 1; a plurality of stirring members 23 are arranged on the upper surface of the drying plate 2; the stirring member 23 is arranged obliquely; the stirring member 23 can scoop up the material on the upper surface of the drying plate 2; the material can flow along the upper surface of the stirring member 23 and fall from the upper end.

[0033] In this embodiment, the lower surface of the stirring member 23 is fixedly connected to the blocking block 6 ; the blocking block 6 is fixedly connected to the lower end of the stirring member 23 ; the blocking block 6 can block the angle between the lower surface of the stirring member 23 and the upper surface of the corresponding drying plate 2 .

[0034] During operation, after the control valve in the feed pipe 11 is opened, the calcium hydrogen phosphate materials of different particle sizes are introduced into the drying cylinder 1 along the feed pipe 11, and the materials will fall onto the upper surface of the top drying plate 2. Then, after the feed pipe 11 and the discharge pipe 12 are closed, the motor 51, the air pump 4 and the heater 42 are started. The reflux pipe 41 is connected in series with the heater 42 and the dehydration component 43. When the air pump 4 is working, the gas in the reflux chamber 22 will be drawn into the dehydration component 43 along the reflux pipe 41. The dehydration component 43 will absorb the moisture in the gas. Then the gas will flow from the dehydration component 43 into the heater 42. After the heater 42 heats the gas, it will enter the air pump 4 along the reflux pipe 41, and then be discharged to the top of the drying cylinder 1 along the air pump 4. The hot gas will pass through from top to bottom in sequence. Drying plate 2, during the operation of air pump 4, motor 51 will drive main shaft 5 to rotate, and during the rotation of main shaft 5, stirring member 23 will be driven to rotate synchronously, and the rotation direction of main shaft 5 is positive, so stirring member 23 is also positive along with the rotation direction of main shaft 5, and stirring member 23 will drive block 6 on the lower surface to move synchronously during its rotation, and stirring member 23 can scoop up materials on the upper surface of drying plate 2 during its rotation, and due to the setting of block 6, the strength of the lower end of stirring member 23 is improved, so that the lower end of stirring member 23 is not easy to deform, and the durability is improved, and as stirring member 23 scoops up materials on the upper surface of drying plate 2, materials will flow along the upper surface of stirring member 23, and since the vertical height of stirring member 23 in the radial direction of drying cylinder 1 increases as it moves away from main shaft 5, Therefore, even if the material on the upper surface of the stirring member 23 has the effect of centrifugal force, it is difficult for it to move away from the main shaft 5. In this way, the material on the upper surface of the stirring member 23 will be dispersed and fall from the upper end of the stirring member 23. After the upper surface of the drying plate 2 is shoveled away by the mixer, the unobstructed drying holes 21 are guaranteed. In this way, the airflow is more likely to flow along the drying holes 21 just passed by the stirring member 23, that is, the airflow is more likely to flow along the drying holes 21 on the corresponding drying plate 2 on the lower surface of the stirring member 23. The airflow will impact the material falling from the upper end of the stirring member 23, and the airflow will drive the material to enter the lower surface of the stirring member 23 and then fall on the upper surface of the drying plate 2. Part of the material will pass through the drying holes 21 on the drying plate 2 along with the airflow, so that the airflow and the material enter the next drying plate 2 area, and the main shaft 5 rotates. Under the shovel, the multiple stirring members 23 will rotate with the rotation of the main shaft 5, and the multiple stirring members 23 will scoop up the materials on the upper surface of the corresponding drying plate 2, thereby increasing the contact area between the materials and the airflow, and avoiding the accumulation of materials affecting the drying effect. After the upper surface of the drying plate 2 is scooped up, it is easier for the airflow to pass through, thereby ensuring the circulation effect of the hot air. Since the materials are dispersed and fall from the upper end of the stirring members 23, the contact area with the airflow is further increased. If the materials falling on the upper surface of the drying plate 2 are small, they can be taken away together with the airflow, while the larger materials are intercepted by the drying holes 21 on the corresponding drying plate 2. The specifications of the drying holes 21 on the multiple drying plates 2 decrease from top to bottom, so the materials of different specifications are intercepted on the upper surface of the corresponding drying plate 2, thereby realizing the separate drying of the materials.The drying plate 2 at the bottom can only pass the airflow but not the materials, so the materials with the smallest specifications are intercepted and collected. With the cooperation of the drying plate 2 and the stirring member 23, the materials are dried in layers according to their specifications. The temperature required for drying the materials with large particles is higher than that required for drying the materials with small particles. The principle of drying refers to utilizing the heat contained in the gas to be absorbed by the moisture in the materials. After absorbing the heat, the moisture evaporates to form water vapor, which flows from top to bottom with the airflow, so that the airflow temperature in the drying cylinder 1 decreases from top to bottom. That is to say, the lower the drying cylinder 1 is, the less heat is contained in the airflow, and the higher the drying cylinder 1 is, the more heat is contained in the airflow. In this way, the airflow with higher heat is more effective for materials with larger specifications. Drying is performed, and the airflow with less heat dries the materials with smaller specifications, so that both large and small particles can be dried at their respective temperatures, thereby improving the uniformity of material drying; the airflow flowing into the reflux chamber 22 will drive the water vapor to flow along the reflux pipe 41. Since the reflux airflow of the air pump 4 is the airflow in the drying cylinder 1, on the one hand, the residual heat in the airflow can be recycled, and on the other hand, the external gas is prevented from polluting the materials in the drying cylinder 1, thereby achieving the purpose of protecting the materials. The airflow passing through the drying plate 2 is subjected to the dual effects of the air pressure above and the negative pressure below, so that the force and speed of the airflow passing through the drying plate 2 are improved, so that the layered drying efficiency of the materials is improved;,

[0035] After the drying of the material is completed, the air pump 4, the heater 42 and the water removal component 43 are stopped, and the control valve in the discharge pipe 12 is opened to control the motor 51 to reverse. The reversed motor 51 can drive the main shaft 5 and the stirring member 23 to reverse. The stirring member 23 will drive the block 6 to reverse during the reversal process. The block 6 can scrape and collect the material on the upper surface of the drying plate 2 during the reversal process. The stirring member 23 can also scrape the material attached to the inner wall of the drying cylinder 1, so that the material is collected at the angle between the stirring member 23 and the upper surface of the corresponding drying plate 2. Since the angle formed between the upper surface of the drying plate 2 and the corresponding stirring member 23 is fixed to the block 6, the material will not be stuck at the angle formed between the upper surface of the drying plate 2 and the stirring member 23. In this way, the material on the upper surface of the drying plate 2 can be pushed by the block 6. The material will generate centrifugal force during the circumferential pushing of the block 6, so that the material is discharged along the discharge pipe 12, thus completing the entire material drying process;

[0036] In this embodiment, the drying holes 21 of different specifications on the multiple drying plates 2 cooperate with the hot air flow flowing from top to bottom, so that materials of different specifications can be dried at their respective corresponding temperatures, thereby improving the uniformity of material drying, and indirectly improving the quality of calcium hydrogen phosphate;

[0037] In this embodiment, the plate-shaped stirring member 23 is used to scoop up the materials on the upper surface of the drying plate 2, thereby ensuring the unobstructed drying holes 21 on the drying plate 2 and the hot air circulation effect, and on the other hand, increasing the contact area between the materials and the airflow, avoiding the accumulation of materials that affects the drying effect, so that the uniformity of material drying is further improved. Embodiment 2:

[0038] A loosening groove 61 is provided on one side of the blocking block 6 that pushes the material on the upper surface of the drying plate 2; the depth of the loosening groove 61 decreases as it moves away from the main shaft 5; the bottom of the loosening groove 61 is slidably connected to a loosening block 62; the loosening block 62 is connected to the wall of the loosening groove 61 on the side close to the main shaft 5 through a tension spring 63; the notch of the loosening groove 61 is fixedly connected to an elastic membrane 64; the loosening block 62 is arranged in contact with the elastic membrane 64; the outer wall of the drying cylinder 1 is vertically embedded with a magnetic strip 13 near the discharge pipe 12; the loosening block 62 is attracted by the magnetic strip 13.

[0039] In this embodiment, the outer wall of the discharge pipe 12 is connected to the branch pipe 14; the discharge pipe 12 is closed at one end away from the drying cylinder 1; the discharge pipe 12 is movably sealed and connected to the valve plate 15 at one end close to the drying cylinder 1; the end face of the valve plate 15 is adapted to the inner wall of the drying cylinder 1; the discharge pipe 12 is fixedly connected to the electric push rod 16 at one end away from the drying cylinder 1; the output shaft of the electric push rod 16 extends into the interior of the discharge pipe 12 and is fixedly connected to the valve plate 15.

[0040] During operation, in the drying process, the valve plate 15 is located at one end of the discharge pipe 12 close to the drying cylinder 1 to close the discharge pipe 12. The end face of the valve plate 15 is adapted to the inner wall of the drying cylinder 1, thereby preventing the material from remaining in a dead corner in the discharge pipe 12 during the drying process. As the material is dried, the electric push rod 16 shortens and drives the valve plate 15 away from the main shaft 5. The valve plate 15 passes over the branch pipe 14, so that the branch pipe 14 is connected to the inside of the drying cylinder 1 through the discharge pipe 12. The motor 51 drives the stirring member 23 and the blocking block 6 to reverse. The blocking block 6 pushes the material on the upper surface of the drying plate 2. Since the magnetic strip 13 is arranged close to the discharge pipe 12, the blocking block 6 moves away from the discharge pipe 12 as the main shaft 5 rotates. The loosening block 62 is attracted by the magnetic strip 13 less, so that the loosening block 62 is pulled close to the main shaft 5. The main shaft 5 moves, and as the blocking block 6 moves closer to the discharge pipe 12 as the main shaft 5 rotates, the loosening block 62 is subject to increased magnetic attraction of the magnetic strip 13, and the loosening block 62 moves along the bottom of the loosening groove 61 away from the main shaft 5 under the magnetic attraction, and the loosening block 62 will pull the tension spring 63. Since the depth of the loosening groove 61 becomes shallower as it moves away from the main shaft 5, the loosening block 62 will squeeze the elastic film 64, so that the elastic film 64 on the blocking block 6 is deformed, and the deformed elastic film 64 will squeeze the material around the blocking block 6, so that the material close to the blocking block 6 is squeezed and loosened, and the conveyed material is pushed by the blocking block 6 to approach the discharge pipe 12, and the loosened material is easier to detach from the angle between the upper surface of the drying plate 2 and the stirring member 23 under the action of centrifugal force, thereby improving the material discharge effect. Embodiment 3:

[0044] During operation, the drying equipment needs to be cleaned regularly. Specifically, the hook 17 is fastened by a crane, and then the hook 17 and the drying cylinder 1 are lifted. The lower end of the drying cylinder 1 is moved out of the placement groove 32. The drying cylinder 1 will drive the anti-rotation block 19 to move out of the anti-rotation groove 33. The drying cylinder 1 will continue to move upward, so that multiple blocks 24 will slide in the same groove 18. During the upward movement of the drying cylinder 1, the upper rod 52 will be driven to separate from the uppermost middle rod 53, so that multiple drying plates 2 and multiple stirring members 23 are exposed. Then the staff starts to clean. If the drying plates 2 and the stirring members 23 need to be replaced, it is only necessary to control the middle rod 53 to move upward. During the upward movement of the middle rod 53, the adjacent The middle rod 53 is disengaged, and the adjacent middle rods 53 are plugged into the square bars 55 through the square grooves 56. After the replacement, cleaning and disinfection of the drying plate 2 and the stirring member 23 are completed, the drying cylinder 1 is controlled to move downward. During the downward movement of the drying cylinder 1, the card slot 18 will be driven to align with the card block 24, and one end of the card slot 18 will be opened, so that it is convenient for the card block 24 to enter the card slot 18.
