Abstract
Description
Technical Field
[0001] This utility model relates to the field of disc dryer technology, and in particular to a disc dryer with a cooling mechanism. Background Technology
[0002] A disc dryer is a high-efficiency, energy-saving intermittent or continuous drying equipment that primarily uses conduction heat transfer. Its core design aims to achieve efficient heat transfer through close contact between the hollow heating disc and the material.
[0003] Traditional disc dryers are designed primarily for heating and drying, neglecting the ability to actively and rapidly cool materials at the end of the drying process. In other words, traditional equipment lacks a corresponding cooling mechanism. After the final drying stage, the material is usually discharged directly from the equipment at a temperature of 60°C to 100°C or even higher. Without intervention to cool it down, the quality of the material may be affected. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a disc dryer with a cooling mechanism.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A disc dryer with a cooling mechanism includes a machine body, a discharge pipe at the bottom of the machine body connected to a cooling box, a guide plate inclinedly arranged inside the cooling box to receive materials, an electric turntable rotatably mounted in the middle of the guide plate, a heat exchange plate arranged above the electric turntable, a plurality of annular grooves opened in the middle of the heat exchange plate, a push rod installed in each annular groove, and the push rods are mounted on the electric turntable. The electric turntable has a feeding hole in the middle, and the bottom of the feeding hole is connected to the discharge port.
[0006] In addition, a preferred structure is that an inclined platform is installed on one side of the interior of the cooling box, the highest point of the inclined platform is directly opposite the discharge pipe, and a guide plate is installed on the upper part of the inclined platform.
[0007] In addition, a preferred structure is that an electric turntable is installed in the middle of the guide plate, and the electric turntable and the guide plate are spliced together to form a complete guide plane.
[0008] In addition, a preferred structure is that a heat exchange plate is mounted on the middle of the guide plate via a mounting bracket, the heat exchange plate is coaxial with the electric turntable, and a gap is left between the heat exchange plate and the electric turntable.
[0009] In addition, a preferred structure is that a through feed groove 1 is provided on the outer wall of the heat exchange plate, and a feed groove 2 is provided on the bottom side of the inner wall of the heat exchange plate.
[0010] The beneficial effects of this utility model are as follows: In this invention, a continuously rotating electric turntable, in conjunction with a push rod, continuously conveys and contacts the material in the heat exchange plate to achieve a continuous heat exchange and cooling effect. At the same time, the push rod pushes the material step by step until it is discharged. During this process, the material fully contacts the heat exchange plate and cools down, effectively achieving the cooling effect on the material. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Reference Figure 1-5 A disc dryer with a cooling mechanism includes a body 1, a discharge pipe 101 at the bottom of the body 1 connected to a cooling box 2, a guide plate 4 inclined inside the cooling box 2 to receive materials, an electric turntable 9 rotatably mounted in the middle of the guide plate 4, a heat exchange plate 5 above the electric turntable 9, a plurality of annular grooves opened in the middle of the heat exchange plate 5, a push rod 92 installed in each annular groove, and the push rod 92 is mounted on the electric turntable 9; The electric turntable 9 has a feeding hole 91 in the middle, and the bottom of the feeding hole 91 is connected to the discharge port 3. The feeding hole 91 guides the processed material inside the machine body 1 into the cooling box 2.
[0015] An inclined platform 6 is installed on one side of the interior of the cooling box 2. The highest point of the inclined platform 6 is directly opposite the discharge pipe 101, and a guide plate 4 is installed on the upper part of the inclined platform 6. The material will continue to roll downward under the inclination.
[0016] An electric turntable 9 is installed in the middle of the guide plate 4. The electric turntable 9 and the guide plate 4 are spliced together to form a complete guide plane.
[0017] The electric turntable 9 includes a motor and a turntable. The motor is installed inside the tilting stage 6, and the output end of the motor drives the turntable. The rotation of the motor drives the turntable to rotate. Driving the components to perform motion through the motor is a conventional technical solution in this field. The specific motor model, operating principle, installation method, electrical control method, feed parameters, etc. are all common knowledge to those skilled in the art.
[0018] A heat exchange plate 5 is mounted on the middle of the feed tray 4 via a mounting bracket 7. The heat exchange plate 5 is coaxial with the electric turntable 9, and a gap is left between the heat exchange plate 5 and the electric turntable 9.
[0019] The heat exchange plate 5 has a multi-ring structure, with each ring connected by a water pipe. The outermost ring of the heat exchange plate 5 is equipped with an inlet pipe, and the innermost ring is equipped with an outlet pipe. The inlet pipe and outlet pipe together form a circulation pipe 51, which is connected to an external chiller to achieve the circulation of coolant. The chiller is existing technology, and its internal structure and operating principle are common knowledge to those skilled in the art.
[0020] A through feed trough 8 is provided on the outer wall of the heat exchange plate 5, and a second feed trough 81 is provided on the bottom side of the inner wall of the heat exchange plate 5.
[0021] In this embodiment, the dried material is discharged into the cooling box 2 through the discharge pipe 101 by the machine body 1. The material falls into the guide plate 4 and enters the material channel formed by the heat exchange plate 5, the electric turntable 9, and the guide plate 4. At this time, the electric turntable 9 drives multiple push rods 92 to rotate. Each push rod 92 rotates in the middle of the heat exchange plate 5 and pushes the material entering the heat exchange plate 5 to move. During this process, the material continuously moves and contacts the heat exchange plate 5 and exchanges heat with the heat exchange plate 5 to achieve a cooling effect. As the material is pushed by the push rod 92, it gradually enters the inner heat exchange plate 5 from the outer feed trough 81 and finally enters the discharge hole 91 to complete the discharge of the discharge port 3.
[0022] As the electric turntable 9 drives the push rod 92 to rotate, and the heat exchange plate 5 remains stationary, in conjunction with the tilting mechanism of the tilting table 6, the material will continue to move due to the tilting and rolling. As the push rod 92 continues to move, it will eventually completely enter the innermost heat exchange plate 5.
[0023] In addition, it should be noted that the body 1, namely the disc dryer body, integrates the cooling box 2 into the discharge pipe 101 of the disc dryer body to achieve cooling treatment of the high-temperature material that has just been processed, effectively ensuring the stability of the material. The specific internal structure and operating principle of the disc dryer are common knowledge to those skilled in the art and will not be explained further. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
