Description

Technical Field

[0001] This utility model relates to the field of dust prevention and diffusion prevention technology for centrifugally dried materials, specifically a device for preventing the diffusion of solid centrifugally dried materials via tubular chain conveying. Background Technology

[0002] Solid centrifugal drying refers to a centrifugal dryer that removes most of the free moisture from solid materials through centrifugal force before drying.

[0003] The materials after centrifugation are usually in the form of fine particles or powder (such as chemical intermediates, pharmaceutical raw materials, food powders, etc.). During the transfer process, dust is easily generated due to vibration, airflow or improper operation. Long-term inhalation of dust may lead to respiratory diseases (such as pneumoconiosis) or allergic reactions, which poses a greater threat to workers in the fine chemical and pharmaceutical industries. Therefore, there is a need to provide a method that can use tubular chain conveying equipment to achieve closed material transport and reduce dust diffusion. Utility Model Content

[0004] The purpose of this invention is to provide a device for preventing the diffusion of solid centrifugal drying materials using a tubular chain conveyor, thereby solving the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution:

[0006] A centrifugal dryer and a discharge port, wherein the discharge port is connected to the lower surface of the centrifugal dryer;

[0007] The conveying assembly includes a feeding frame, a motor, a rotating shaft, and a feeding port. The feeding frame is located outside and below the centrifugal dryer. The motor is fixed to one side of the feeding frame, and the rotating shaft is fixed to the output end of the motor and rotates through the inside of the feeding frame. The feeding port is opened on the lower surface of the feeding frame.

[0008] Furthermore, a feed inlet is fixed on one side of the upper end of the centrifugal dryer, and a support frame is fixed on the lower surface of the centrifugal dryer.

[0009] Furthermore, a flexible tube is fixed to one side of the feeding frame, and a threaded plate rotates through the inside of the flexible tube.

[0015] This utility model relates to a centrifugal dryer, including an inlet, an outlet, a support frame, and a conveying assembly. After the dried material is conveyed, a fixing ring is inserted through the outer surface of the outlet, allowing the threaded plate inside the hose to extend into the outlet. Then, the motor is started, driving the rotating shaft to rotate, which in turn drives the threaded plate to rotate.

This prevents dust from spreading. The threaded plate forms a dynamic seal with the inner wall of the hose during rotation, keeping the material in a closed state throughout the conveying process, significantly reducing dust leakage, improving the working environment, and lowering occupational health risks.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is a device for preventing the diffusion of solid centrifugal drying materials using a tubular chain conveyor, comprising:

[0028] Centrifugal dryer 11 and discharge port 13 are connected to the lower surface of centrifugal dryer 11. A feed inlet 12 is fixed on one side of the upper end of centrifugal dryer 11, and a support frame 14 is fixed on the lower surface of centrifugal dryer 11.

[0029] The core function of the centrifugal dryer 11 is to separate liquids such as water and solvents from solids in wet materials by using centrifugal force generated by high-speed rotation. The discharge port 13 is the connecting component between the centrifuge and the subsequent conveying system, used to output the centrifuged solid material to the conveying assembly. The support frame 14 is used to fix the centrifugal dryer 11 to ensure its stable operation.

[0030] The conveying assembly includes a feeding frame 21, a motor 23, a rotating shaft 24, and a feeding port 25. The feeding frame 21 is located on the outside and below the centrifugal dryer 11. The motor 23 is fixed on one side of the feeding frame 21. The rotating shaft 24 is fixed to the output end of the motor 23 and rotates through the inside of the feeding frame 21. The feeding port 25 is opened on the lower surface of the feeding frame 21.

[0031] The feeding frame 21 is used to receive materials conveyed from the hose 27. The motor 23 provides power to drive the rotating shaft 24 and the threaded plate 26 to rotate. The rotating shaft 24 connects the motor 23 and the threaded plate 26 to transmit rotational power. The feeding port 25 is located at the bottom of the feeding frame 21 and is the final output channel for the material.

[0032] A flexible tube 27 is fixed on one side of the feeding frame 21, and a threaded plate 26 rotates through the inside of the flexible tube 27. A fixing ring 28 is fixed at the end of the flexible tube 27, and the fixing ring 28 passes through the outer surface of the discharge port 13. The end of the threaded plate 26 extends into the discharge port 13, and a base frame 22 is fixed on the lower surface of the feeding frame 21.

[0033] Hose 27 is a flexible pipe connecting outlet 13 and conveying assembly, used to convey materials in the centrifuge to discharge frame 21. Threaded plate 26 is the core component of the conveying system, which pushes materials from the centrifuge to discharge frame 21 by rotation. Threaded plate 26 adopts a spiral structure, generating axial thrust by rotation to convey materials along hose 27. Fixing ring 28 is used to tightly connect hose 27 to outlet 13 to ensure the sealing of the conveying system.

[0034] Working principle:

[0035] After the dried material is conveyed, the fixing ring 28 is inserted through the outer surface of the discharge port 13, so that the threaded plate 26 inside the hose 27 extends into the discharge port 13. Then the motor 23 is started, and the motor 23 drives the rotating shaft 24 to rotate. The rotating shaft 24 drives the threaded plate 26 to rotate, so that the material inside the centrifugal dryer 11 is gradually conveyed from the hose 27 to the discharge frame 21 under the action of the rotating threaded plate 26, and finally transferred from the discharge port 25 to avoid dust diffusion.

[0036] In this step, the threaded plate 26 forms a dynamic seal with the inner wall of the hose 27 when it rotates, so that the material is always in a closed state during the conveying process, which significantly reduces dust leakage, improves the working environment, and reduces occupational health risks.

[0037] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The mounting assembly includes a connecting rod 31, mounting holes 32, a spring 33, and a locking post 34. The connecting rod 31 is fixed on both sides of the outer surface of the discharge port 13. The mounting holes 32 are opened on both sides of the lower end of the connecting rod 31. The spring 33 is fixed inside the mounting holes 32. The locking post 34 is fixed to one end of the spring 33. The upper end of the fixing ring 28 has mounting grooves 35 on both sides. The fixing ring 28 has locking slots 36 on both sides, and the locking slots 36 and the mounting grooves 35 are interconnected. The end of the locking post 34 extends into the locking slot 36.

[0039] The connecting rod 31 is a rigid component fixed to the outer surface of the discharge port 13, used to provide support and positioning for the mounting assembly. The mounting hole 32 is used to accommodate the spring 33 and the locking post 34. The spring 33 is the core elastic element of the mounting assembly, used to provide restoring force and buffering effect. The locking post 34 is used to cooperate with the locking groove 36 to fix the fixing ring 28.

[0040] The mounting slot 35 is used to cooperate with the connecting rod 31 to achieve initial positioning, and the slot 36 is used to cooperate with the locking post 34 to achieve final locking.

[0041] Working principle:

[0042] When connecting the hose 27, insert the retaining ring 28 into the discharge port 13, align the connecting rod 31 with the mounting groove 35, and insert the end of the connecting rod 31 into the mounting groove 35. Press the retaining post 34 to compress the spring 33 into the mounting hole 32. When the retaining post 34 is aligned with the groove 36, the spring 33 will quickly recover its deformation under the elastic force of the spring 33, driving the retaining post 34 into the groove 36, and installing the retaining ring 28 on the outer surface of the discharge port 13.

[0043] In this step, the connection method of the fixing ring 28 is achieved through the spring 33 reset buckle structure, which realizes high efficiency, reliability and connection effect.
