Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically a novel high-efficiency progressive stirring single cone dryer. Background Technology

[0002] A single cone dryer is a mechanical device that uses heat energy to reduce the moisture content of materials, used for drying objects. The dryer heats the material to vaporize and release the moisture (generally water or other volatile liquid components) to obtain a solid material with a specified moisture content.

[0003] The existing single cone dryer lacks a pre-crushing structure at the feed inlet, which causes the material to dry for too long and reduces the drying efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a novel, highly efficient, progressive stirring single-cone dryer.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel high-efficiency progressive stirring single cone dryer, comprising a single cone dryer body, a feed cylinder at the feed end of the single cone dryer body, an annular frame rotatably mounted on the top of the feed cylinder, a centrifugal cylinder inserted into the feed cylinder at the inner ring of the annular frame, a plurality of through holes on the periphery of the centrifugal cylinder, a toothed ring on the periphery of the annular frame, a first motor fixedly mounted at the upper end of the single cone dryer body, and a gear meshing with the toothed ring at the output end of the first motor;

[0008] A second motor is fixedly installed above the feed cylinder, and the output end of the second motor is provided with a crushing shaft that is inserted into the centrifuge cylinder.

[0009] To facilitate material feeding, the present invention includes an improvement where a conical cylinder is provided at the upper end of the feed cylinder.

[0010] To improve the stability of the ring frame during rotation, the present invention includes the following improvements: the top end of the feed cylinder and the bottom end of the conical cylinder are provided with annular grooves; the upper end and lower end of the ring frame are provided with annular blocks that are inserted into the annular grooves and rotatably connected to the annular grooves; the annular grooves are embedded with bearings; and the annular blocks penetrate the inner ring of the bearings.

[0011] Furthermore, an improvement of this utility model is that the annular frame and the centrifuge cylinder are an integrated structure.

[0012] Furthermore, an improvement of this utility model is that both the first motor and the second motor are servo motors.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a novel high-efficiency progressive stirring single cone dryer, which has the following beneficial effects:

[0015] The centrifugal drum and crushing shaft at the feed end form a linked crushing structure, so the material is crushed and screened during the feeding process, avoiding the inefficiency caused by long drying times for large particles entering the dryer. Crushing and centrifugal screening are carried out simultaneously, which improves the uniformity of material particle size, shortens the drying time, and improves overall efficiency.

[0016] The centrifugal force generated by the rotation of the centrifuge drum separates the material according to particle size, ensuring that only particles that meet the requirements enter the dryer. This avoids the inconsistent drying effect caused by uneven particle size in traditional dryers. The uniform material state results in a more stable moisture content in the dried product, guaranteeing consistent quality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1-4This utility model discloses a novel high-efficiency progressive stirring single cone dryer, comprising a single cone dryer body 1, a feed cylinder 2 at the feed end of the single cone dryer body 1, an annular frame 4 rotatably mounted on the top of the feed cylinder 2, a centrifugal cylinder 5 inserted into the feed cylinder 2 on the inner ring of the annular frame 4, a plurality of through holes on the periphery of the centrifugal cylinder 5, a toothed ring 8 on the periphery of the annular frame 4, a first motor 9 fixedly mounted on the upper end of the single cone dryer body 1, and a gear 10 meshing with the toothed ring 8 at the output end of the first motor 9;

[0024] A second motor 11 is fixedly installed above the feed cylinder 2, and the output end of the second motor 11 is provided with a crushing shaft 12 that is inserted into the centrifuge cylinder 5.

[0025] The ring frame 4 and the centrifuge tube 5 are an integrated structure.

[0026] After entering the feed cylinder 2 through the conical cylinder 3, the material falls into the centrifugal cylinder 5. At this time, the second motor 11 drives the crushing shaft 12 to rotate at high speed, performing preliminary crushing of the material. Simultaneously, the first motor 9, through the meshing of the gear 10 and the gear ring 8, drives the ring frame 4 and the centrifugal cylinder 5 to rotate inside the feed cylinder 2. The centrifugal force generated by the rotation of the centrifugal cylinder 5 causes the crushed material to move towards the cylinder wall. Material that meets the particle size requirements enters the feed cylinder 2 through the peripheral through-holes and then falls into the single cone dryer body 1 for drying; large particles that do not meet the requirements continue to be crushed and ground by the crushing shaft 12 inside the centrifugal cylinder 5 until they meet the size requirements and then fall through the through-holes.

[0027] The top end of the feed cylinder 2 and the bottom end of the conical cylinder 3 are both provided with annular grooves 6. The upper and lower ends of the annular frame 4 are provided with annular blocks 7 that are inserted into the annular grooves 6 and rotatably connected to the annular grooves 6. The annular grooves 6 are embedded with bearings, and the annular blocks 7 penetrate the inner ring of the bearings.

[0028] The feed cylinder 2 and the conical cylinder 3 are connected by an annular groove 6 and an annular block 7. The internal bearing supports the rotation of the annular frame 4 to ensure the stability of the centrifuge cylinder 5 when it rotates.

[0029] Both the first motor 9 and the second motor 11 are servo motors.

[0030] The servo motor precisely controls the rotation speed of the crushing shaft 12 and the rotation speed of the centrifuge drum 5, forming a progressive crushing and screening process, so that the material is pre-treated before entering the dryer, providing a uniform material state for the subsequent drying process.

[0031] The annular frame 4, installed through the cooperation of the annular groove 6, annular block 7, and bearings, ensures the smooth rotation of the centrifuge cylinder 5 and reduces vibration and noise during equipment operation. The integrated structure of the annular frame 4 and centrifuge cylinder 5 enhances the overall mechanical strength, prevents structural loosening under long-term high-speed operation, and extends the service life of the equipment.

[0032] The first motor 9 and the second motor 11 are servo motors, which can precisely adjust the speed of the crushing shaft 12 and the rotation speed of the centrifuge drum 5 according to the material characteristics, adapting to the crushing requirements of different materials. Precise control makes the crushing and screening process more controllable, especially suitable for the pretreatment of materials with strict particle size requirements, improving the applicability and process flexibility of the equipment.

[0033] The upper end of the feed cylinder 2 is provided with a conical cylinder 3.

[0034] The conical cylinder 3 at the top of the feed cylinder 2 facilitates the smooth flow of materials into the centrifuge cylinder 5, reducing accumulation and blockage during feeding. The inclined conical surface guides the material to quickly enter the processing area, improving feeding efficiency and reducing the need for manual intervention, making the entire drying process smoother.

[0035] Model 9 of the first motor: Servo motor (such as Panasonic MINASA6 series).

[0036] Second motor model 11: Servo motor (such as Siemens V90 series).

[0037] Centrifuge cylinder 5 is made of 304 stainless steel (inner wall mirror polished, Ra≤0.8μm).

[0038] Through hole specifications: φ2~5mm (hole diameter can be customized).

[0039] Crusher shaft 12 material: 420 stainless steel (surface hardening treatment, hardness HRC45~50).

[0040] Ring frame 4 is made of Q345B carbon steel (zinc-plated).
