Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically to a feeding device for a dryer. Background Technology

[0002] In the production of copper oxide, the rotary kiln dryer plays a crucial role. It efficiently dries copper oxide materials in a high-temperature environment, ensuring that the copper oxide product meets the corresponding quality standards, and is of great significance in improving product performance and stability.

[0003] Currently, in copper oxide production, rotary kiln dryers are primarily fed using conveyor belts. When the conveyor belt transports the material to the rotary kiln dryer's feeding device, the material falls freely from the belt into the device. This traditional feeding method has significant drawbacks, as the falling material generates considerable noise. Firstly, noise pollution negatively impacts the working environment; prolonged exposure to high-decibel noise can easily lead to hearing damage for operators, reducing work comfort and consequently affecting work efficiency and quality. Secondly, excessive noise may also trigger complaints from nearby residents, causing unnecessary environmental disputes for the company.

[0004] Furthermore, noise generation reflects energy waste and unreasonable mechanical impact during material conveying. This impact not only causes wear and tear on the feeding device, shortening equipment lifespan and increasing maintenance costs, but also potentially affects material conveying stability, interfering with subsequent drying processes and leading to fluctuations in copper oxide product quality. Therefore, developing a device that effectively reduces feeding noise is an urgent practical need for improving copper oxide production efficiency, optimizing the production environment, and ensuring product quality. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a feeding device for a dryer.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0007] A feeding device for a dryer includes a material cylinder. A receiving plate is provided on the top left wall of the material cylinder, and the right end of the receiving plate extends into the material cylinder. A support plate is provided between the left side wall of the receiving plate and the left inner wall of the material cylinder. A baffle is provided on the right inner wall of the material cylinder. A conveying pipe is provided on the bottom wall of the material cylinder. A base is provided on the bottom wall of the conveying pipe. A motor is provided on the bottom wall of the base. A rotating rod is locked to the output end of the motor through a coupling. The outer wall of the rotating rod is rotatably connected to the inner wall of the base through a bearing. Bolt blades are provided on the outer wall of the rotating rod.

[0008] Furthermore, the receiving plate is inclined.

[0009] Furthermore, the inner bottom wall of the material cylinder is arc-shaped.

[0010] Furthermore, a buffer pad is provided on the left side wall of the baffle.

[0011] Furthermore, the conveying pipe includes a vertical pipe 1 and an inclined pipe 2, and the pipe 1 and the pipe 2 are welded together.

[0012] The beneficial effects of this utility model are:

[0013] This invention utilizes a receiving plate to catch materials unloaded from the conveyor belt, significantly reducing the material's fall height and initial noise caused by free fall. The baffle and its outer wall cushioning effectively buffer the impact of the material, reducing the impact noise when the material contacts the baffle. This series of designs significantly improves the working environment, effectively preventing operators from being exposed to high-decibel noise for extended periods, reducing the risk of hearing damage, and improving work comfort. This, in turn, ensures work efficiency and quality, while also reducing the likelihood of noise complaints from nearby residents and preventing the company from getting involved in environmental disputes.

[0014] The motor drives the rotating rod and bolt blades to rotate, smoothly conveying the material in the cylinder downwards into the feed pipe, and then into the rotary kiln dryer. Compared with the traditional free-fall feeding method, this conveying method effectively avoids disorder and instability in the material conveying process, ensuring that the material can enter the dryer evenly and continuously. This provides a stable material supply for subsequent drying processes, which helps to improve the stability and consistency of the drying process, ensure the stability of copper oxide product quality, and reduce product quality fluctuations caused by unstable material conveying.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figure 1-2 As shown, a feeding device for a dryer includes a material cylinder 1. A receiving plate 2 is provided on the top left wall of the material cylinder 1, and the right end of the receiving plate 2 extends into the material cylinder 1. A support plate 3 is provided between the left side wall of the receiving plate 2 and the left inner wall of the material cylinder 1. A baffle 4 is provided on the right inner wall of the material cylinder 1. A conveying pipe 5 is provided on the bottom wall of the material cylinder 1. A base 6 is provided on the bottom wall of the conveying pipe 5. A motor 7 is provided on the bottom wall of the base 6. A rotating rod 8 is locked to the output end of the motor 7 through a coupling. The outer wall of the rotating rod 8 is rotatably connected to the inner wall of the base 6 through a bearing. Bolt blades 9 are provided on the outer wall of the rotating rod 8.

[0022] Furthermore, the receiving plate 2 is inclined and is used to receive the material unloaded from the unloading end of the conveyor belt. The material slides down the outer wall of the receiving plate 2 into the feed cylinder 1, and the receiving plate 2 reduces the height of the material falling.

[0023] Furthermore, the inner bottom wall of the material cylinder 1 is arc-shaped, which facilitates the downward accumulation of materials entering the material cylinder 1 and their entry into the conveying pipe 5.

[0024] Furthermore, a buffer pad is provided on the left side wall of the baffle 4 to buffer the material. The buffer pad on the outer wall of the baffle 4 can reduce the impact noise when the material comes into contact with the baffle 4.

[0025] Furthermore, the conveying pipe 5 includes a vertical pipe 1 and an inclined pipe 2, and the pipe 1 and the pipe 2 are welded together. After the motor 7 is started, the rotating rod 8 drives the bolt blade 9 to rotate. The rotating rod 8 and the bolt blade 9 rotate to convey the material in the material cylinder 1 downward into the conveying pipe 5, and then convey it into the rotary kiln dryer through the right end of the conveying pipe 5.

[0026] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0027] One specific application of this embodiment is:

[0028] When using the low-noise feeding device of the rotary kiln dryer for copper oxide production, the specific operation process is as follows: First, the receiving plate 2 is precisely located below the discharge end of the conveyor belt. Its inclined outer wall can efficiently receive the copper oxide material discharged from the discharge end of the conveyor belt. Under the action of gravity, the material slides down the outer wall of the receiving plate 2 at a relatively gentle speed into the material cylinder 1. The key to the setting of the receiving plate 2 is to greatly reduce the falling height of the material and effectively avoid the situation that the material generates a large initial noise due to free fall.

[0029] Next, when the material enters the feed cylinder 1, it will meet the baffle 4. As a key component for material buffering, the baffle 4 has a specially made buffer pad attached to its outer wall. The buffer pad is made of a material with good shock absorption performance, such as rubber. When the material impacts the baffle 4, the buffer pad can absorb and disperse the impact force of the material, thereby greatly reducing the impact sound generated when the material comes into contact with the baffle 4, and further reducing noise pollution.

[0030] Subsequently, the motor 7 is started. As a power source, the motor 7 is tightly connected to the rotating rod 8 through the coupling and other transmission components after being powered on, causing the rotating rod 8 to start rotating at high speed. The spirally wound bolt blades 9 on the rotating rod 8 rotate synchronously. During the rotation, the bolt blades 9 continuously push the material in the material cylinder 1. Utilizing the characteristics of its spiral structure, the material is smoothly and orderly conveyed downwards. Under the push of the bolt blades 9, the material gradually enters the conveying pipe 5.

[0031] Finally, the material is smoothly conveyed into the rotary kiln dryer from its right end through the internal channel of the conveying pipe 5. The rotary kiln dryer then performs high-temperature drying on the material, completing the key drying step in the copper oxide production process. The entire feeding process, through the coordinated operation of multiple components such as the receiving plate 2, baffle 4, motor 7, rotating rod 8, and bolt blades 9, achieves low-noise, stable, and efficient conveying of copper oxide material, providing a strong guarantee for the stable operation of the rotary kiln dryer and the production of high-quality copper oxide products.

[0032] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
