Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically to an energy-saving drying device that provides uniform drying. Background Technology

[0002] An energy-efficient drying device for uniform drying is used in the calcium carbonate production process for high-efficiency drying. Its function is to reduce energy consumption and improve drying efficiency by optimizing the utilization of heat energy and airflow. This device helps reduce production costs while ensuring stable product quality.

[0003] A search revealed Chinese patent publication number CN210741017U, which discloses an energy-saving calcium carbonate powder drying device. The device includes a sealed cylinder with an exhaust port, a feed port, and a discharge port. Inside the cylinder are a heat source and a tubular body, with a channel formed between the tubular body and the cylinder. Gaps exist between the tubular body and the top plate of the cylinder, as well as between the tubular body and the bottom plate of the cylinder. A screw is installed inside the tubular body, with one end contacting the bottom plate of the cylinder. A motor is located at the top of the cylinder, with its output end passing through the cylinder and connected to the other end of the screw. However, this device still has the following problems:

[0004] In existing technologies, the waste gas generated during the drying of calcium carbonate contains dust and harmful gases. Direct emission of these gases will pollute the environment and endanger human health. However, during the drying process in the drying drum, due to the open feed port, some waste gas is often discharged directly through the feed port opening without being filtered, resulting in environmental pollution and odor diffusion.

[0005] Based on this, the present invention designs an energy-saving drying device that provides uniform drying to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an energy-saving drying device that provides uniform drying.

Multiple baffles are also fixedly connected to the inner wall of the cylinder shell.

[0010] Furthermore, the drive mechanism includes a motor, a drive gear, and a gear ring. The bottom of the motor is fixedly connected to the top of the mounting base, and the output end of the motor is fixedly connected to the drive gear.

[0012] Furthermore, the one-way valve includes a fixed ring and a one-way baffle. The outer wall of the fixed ring is fixedly connected to the inner wall of the feed pipe, and the bottom of the fixed ring is rotatably connected to the one-way baffle, and the outer diameter of the one-way baffle is larger than the inner diameter of the fixed ring.

[0013] Furthermore, the reset assembly includes a fixed post, a sleeve, a spring, an extension rod, and a sliding post. The outer wall of the fixed post is fixedly connected to the inner wall of the feed pipe. The middle part of the fixed post is rotatably connected to the sleeve. The inner wall of the sleeve is fixedly connected to the spring. The inner wall of the sleeve is slidably connected to the extension rod. The spring and one end of the extension rod are fixed together. The other end of the extension rod is rotatably connected to the sliding post. The top of the sliding post is slidably connected to the bottom of the one-way baffle.

[0014] Furthermore, the discharge device includes a discharge cylinder, a transmission frame, a rotating shaft, a connecting rod, a scraper, a barrier cylinder, a discharge hopper, and an anti-blocking component. The left end of the discharge cylinder is rotatably connected to the right end of the cylinder shell. The transmission frame is fixedly connected to the inner side of the right end of the cylinder shell. The rotating shaft is fixedly connected to the outer right side of the transmission frame. Multiple connecting rods are fixedly connected to the outer wall of the rotating shaft. A scraper is fixedly connected to one end of each connecting rod. The barrier cylinder is fixedly connected to the right end of the discharge cylinder. The discharge hopper is fixedly connected to the bottom of the discharge cylinder.

[0015] Furthermore, the anti-clogging component includes a rotating tube, an annular bevel gear, a transmission gear, a follower frame, and a spiral feed plate.

[0017] Compared with the prior art, the advantages of this utility model are as follows: 1. During feeding, the gravity of the wet calcium carbonate material drives the one-way baffle to rotate downward, thereby opening the feed pipe. Then, the extension rod slides and compresses the spring inside the sleeve. After feeding is complete, the spring's deformation recovery pushes out the extension rod. Thus, the one-way baffle is driven by the transmission action of the extension rod and the sliding pile to seal the bottom of the fixing ring, thereby preventing the exhaust gas from being discharged directly into the external environment through the feed pipe without treatment, reducing pollution to the atmosphere and other environments.

[0018] 2. The material to be dried enters the discharge cylinder. The rotation of the rotary drying cylinder drives the transmission frame and the ring bevel gear to rotate. The rotation of the transmission frame drives the scraper to rotate via the rotating shaft, scraping off the material from the inner wall of the discharge cylinder, reducing waste. At the same time, the rotation of the ring bevel gear drives the transmission gear to rotate, which in turn drives the rotating tube to rotate. When the rotating tube rotates, it drives the follower frame to rotate, which in turn drives the spiral feeding plate to rotate, thus preventing material from clogging the discharge hopper and ensuring complete discharge. This achieves efficient drying and prevents the accumulation of raw materials on the discharge hopper, which would cause waste of finished products. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the plan view.

[0031] Example 1: In some embodiments, please refer to the accompanying drawings. Figure 1 - Figure 7An energy-saving drying device for uniform drying includes a rotary drying drum 3 and a mounting base 2, as well as drum frames 1, a drive mechanism 4, a feeding device 5, a discharging device 6, a heater 7, a blower 8, and a filter mechanism. Multiple drum frames 1 are located at the bottom of the rotary drying drum 3, and the drive mechanism 4 is located at the top of the mounting base 2. The feeding device 5 is located at the left end of the rotary drying drum 3, and the discharging device 6 is located at the right end. A heater 7 is located at the right end of the discharging device 6, and a blower 8 is connected to the right end of the heater 7. A filter mechanism, which can be an activated carbon adsorption device, is located at the outlet end of the blower 8. A bag filter 9 is located at the left end of the feeding device 5.

[0032] The rotary drying drum 3 includes a drum shell 301, bulk material blocks 302 and baffles 303. The outer wall of the drum shell 301 is rotatably connected to the inner side of multiple fixed supports. Multiple bulk material blocks 302 are fixedly connected to the inner wall of the drum shell 301, and multiple baffles 303 are fixedly connected to the inner wall of the drum shell 301.

[0033] When drying calcium carbonate powder, the rotary drying drum 3 is rotated by turning on the drive mechanism 4, and then calcium carbonate powder is poured into the rotary drying drum 3 through the feeding device 5. At the same time, the blower 8 and the heater 7 are turned on, so that the external air is heated and blown into the rotary drying drum 3. Since the left end of the rotary drying drum 3 is higher than the right end, the powder flows to the right end of the rotary drying drum 3 when it rotates. At the same time, the heated airflow comes into contact with the material, so that the moisture and other gases in the material are carried away by the airflow and enter the bag dust collector 9 for filtration and discharge. The dried material is discharged through the discharge device 6. During the process of blowing in hot air, the material is broken up by the material block 302 for transportation, thereby increasing the contact area between the material and the hot air. The baffle 303 guides the airflow, increasing the movement time of the hot air in the rotary drying drum 3, so that the calcium carbonate powder comes into full contact with the hot air, thereby increasing the overall drying efficiency.

[0034] like Figure 1 and Figure 2 As shown, the drive mechanism 4 includes a motor 401, a drive gear 402 and a gear ring 403. The bottom of the motor 401 is fixedly connected to the top of the mounting base 2. The output end of the motor 401 is fixedly connected to the drive gear 402. Two gear rings 403 are fixedly connected to the outer wall of the rotary drying cylinder 3. The outer side of the gear ring 403 meshes with the outer side of the drive gear 402.

[0035] The operation of motor 401 drives the drive gear 402 to rotate, and the rotation of drive gear 402 drives gear ring 403 to rotate synchronously. Due to the support of the fixed bracket, drive gear 402 is not affected by the gravity of cylinder shell 301, so that cylinder shell 301 rotates stably and synchronously under the rotation of gear ring 403.

[0036] like Figures 5 to 7 As shown, the feeding device 5 includes a feeding cylinder 501, a feeding pipe 502, a one-way valve, and a reset assembly. One end of the feeding cylinder 501 is fixedly connected to one end of the cylinder shell 301. The top of the feeding cylinder 501 is fixedly connected to the feeding pipe 502. The inner wall of the feeding pipe 502 is fixedly connected to the one-way valve. The inner wall of the feeding pipe 502 is fixedly connected to the reset assembly.

[0037] The one-way valve includes a fixed ring 503 and a one-way baffle 504. The outer wall of the fixed ring 503 is fixedly connected to the inner wall of the feed pipe 502. The bottom of the fixed ring 503 is rotatably connected to the one-way baffle 504, and the outer diameter of the one-way baffle 504 is larger than the inner diameter of the fixed ring 503.

[0038] The reset assembly includes a fixed post 505, a sleeve 506, a spring 507, an extension rod 508, and a sliding post 509. The outer wall of the fixed post 505 is fixedly connected to the inner wall of the feed pipe 502. The sleeve 506 is rotatably connected to the middle of the fixed post 505. The spring 507 is fixedly connected to the inner wall of the sleeve 506. The extension rod 508 is slidably connected to the inner wall of the sleeve 506. The spring 507 and the end of the extension rod 508 are fixed together. The other end of the extension rod 508 is rotatably connected to the sliding post 509. The top of the sliding post 509 is slidably connected to the bottom of the one-way baffle 504.

[0039] The feed pipe 502 is fixedly connected to the top of the feed cylinder 501. When raw materials are poured into the feed pipe 502, the gravity of the raw materials causes the one-way baffle 504 to rotate downwards. This causes the extension rod 508 to slide into the sleeve 506 and compress the spring 507 through the sliding of the sliding pile 509. After feeding is completed, the spring 507 restores its deformation and causes the extension rod 508 to slide outwards, thereby causing the sliding pile 509 to slide in the opposite direction. This rotates the one-way baffle 504 upwards until it contacts the bottom of the fixing ring 503, sealing the entire feed pipe 502 and preventing waste gas from being directly discharged through the feed pipe 502 and causing pollution.

[0040] like Figures 2 to 4As shown, the discharge device 6 includes a discharge cylinder 601, a transmission frame 602, a rotating shaft 603, a connecting rod 604, a scraper 605, a barrier cylinder 606, a discharge hopper 607, and an anti-blocking component. The left end of the discharge cylinder 601 is rotatably connected to the right end of the cylinder shell 301. The transmission frame 602 is fixedly connected to the inner side of the right end of the cylinder shell 301. The rotating shaft 603 is fixedly connected to the outer right side of the transmission frame 602. Multiple connecting rods 604 are fixedly connected to the outer wall of the rotating shaft 603. The scraper 605 is fixedly connected to the opposite end of the connecting rod 604. The barrier cylinder 606 is fixedly connected to the right end of the discharge cylinder 601. The discharge hopper 607 is fixedly connected to the bottom of the discharge cylinder 601. An anti-blocking component is provided at the bottom of the discharge hopper 607.

[0041] The anti-clogging assembly includes a rotating tube 608, an annular bevel gear 609, a transmission gear 610, a follower frame 611, and a spiral feed plate 612. The top of the rotating tube 608 is rotatably connected to the bottom of the discharge hopper 607. The bottom of the rotating tube 608 is connected to an external collection box for receiving dried materials. The annular bevel gear 609 is fixedly connected to the outer wall of the cylinder shell 301. The transmission gear 610 is fixedly connected to the outer wall of the rotating tube 608. The outer side of the transmission gear 610 meshes with the bottom of the annular bevel gear 609. The follower frame 611 is fixedly connected to the inner wall of the rotating tube 608. The spiral feed plate 612 is fixedly connected to the outer side of the follower frame 611.

[0042] A baffle plate is fixedly connected to the inner wall of the baffle cylinder 606, and gas flow equalization holes of the same shape and size are evenly distributed on the baffle plate.

[0043] When the dried material enters the discharge cylinder 601, the rotation of the cylinder shell 301 causes the transmission frame 602, which is fixedly connected to it, to rotate. This, in turn, drives the scraper plate 605 to rotate within the discharge cylinder 601 via the transmission action of the rotating shaft 603. This scrapes the material remaining on the inner wall of the discharge cylinder 601 into the discharge hopper 607, thereby reducing raw material waste. Furthermore, the baffle plate inside the baffle cylinder 606 not only prevents material from entering the heater 7 and causing damage, but also evenly distributes the heated air as it passes through, ensuring uniform airflow during subsequent drying and preventing localized drying. The rotation of the cylinder shell 301 also drives the ring bevel gear 609 to rotate, which in turn drives the rotating tube 608 to rotate via the transmission gear 610. The rotation of the rotating tube 608 drives the follower frame 611 to rotate, which in turn drives the spiral feed plate 612 to rotate, preventing blockage inside the discharge hopper 607 and allowing the material to enter the finished product box for collection.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
