[0002] The discharge valve is a device widely used in industrial production, especially in the furnace feeding system, where it plays a vital role. The main function of the furnace feeding system is to transport fuel to the boiler combustion chamber, and the discharge valve is responsible for controlling the flow and speed of the fuel to ensure that the fuel can enter the combustion chamber evenly and continuously. However, when a traditional discharge valve is blocked or needs to be cleaned, it is often necessary to disassemble the entire device, which is not only time-consuming and labor-intensive, but may also cause damage to the equipment. For example, a Chinese patent discloses "a new type of rotary feeding valve" with the application number "200820180034.3". The valve body has an inclined inner wall design and a V-shaped slag inlet formed between the inclined inner wall and the blades to push large-particle materials to slide and be discharged as the impeller rotates, avoiding the phenomenon of directly squeezing the stuck materials to move with the impeller rotation, which causes the equipment to be easily stuck during operation. However, the valve body still has the phenomenon and problem of being inconvenient to clean. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0023] Reference Figure 1-4The embodiment of the present invention is a discharge valve for a furnace feeding system, which includes: a shell 1, which serves as the main structure of the discharge valve and plays the role of protecting internal mechanical components, supporting and connecting other components. The upper surface of the shell 1 is provided with an input port 12, which is used as an inlet for materials to enter the discharge valve, and the lower surface of the shell 1 is provided with an output port 13, which is used as an outlet for materials to be discharged from the discharge valve. The right surface of the shell 1 is fixedly connected with a motor 5, which is used to provide a power source to drive the rotating shaft 8 to rotate, thereby driving the rotating plate 9 to separate and transport the materials. The output end of the motor 5 is fixedly connected with the rotating shaft 8, which is used to transmit the rotating power of the motor 5. The rotating shaft 8 passes through the right surface of the shell 1 and extends to the interior of the shell 1, which is used to ensure that the rotating plate 9 can rotate. The left surface of the shell 1 is provided with a positioning hole 7, which is used to position the rotating shaft 8. The end of the rotating shaft 8 away from the motor 5 is located inside the positioning hole 7, which is used to prevent the rotating shaft 8 from deviating. The side surface of the rotating shaft 8 is fixedly connected with a rotating plate 9, which is used to divide the space inside the shell 1 into multiple material guide chambers to achieve material separation and transportation. The front surface of the shell 1 is connected to a shell door 3 by a hinge, which is used to facilitate opening the interior of the shell 1 and cover and protect the rotating shaft 8 and the rotating plate 9. The front surface of the shell door 3 is movably connected to a lock handle, which is used to facilitate the opening and closing of the shell door 3 and ensure the closure of the shell door 3. The shell door 3 covers the rotating shaft 8 and the rotating plate 9. The upper end surface of the shell 1 is fixedly connected to a mounting ring 2, which is used to fix the discharge valve on the furnace feeding system. The upper surface of the mounting ring 2 is provided with a connecting hole 6 for facilitating the fixation of the device. The mounting ring 2 is located above the input port 12, and the lower end of the shell 1 is fixedly connected to the upper end surface of the shell 1. A joint 11 is fixedly connected to the surface for connecting the guide tube 4. The joint 11 is located below the output port 13. A protrusion is provided at the lower end of the joint 11 to prevent the guide tube 4 from falling off. The side surface of the joint 11 is rotatably connected to the guide tube 4 to adjust the discharge direction of the material. A rotating groove 10 is provided on the side inner wall of the guide tube 4 to achieve rotating connection and stable support of the guide tube 4. The rotating groove 10 is located at the upper end of the guide tube 4, and the protrusion is located inside the rotating groove 10. The guide tube 4 is connected to the outer shell 1, and the guide tube 4 is located directly below the outer shell 1.

[0024] Working principle: The material of the furnace front feeding system first enters the housing 1 of the discharge valve through the input port 12. When the motor 5 is started, its output end drives the rotating shaft 8 to start rotating. The rotational power of the rotating shaft 8 is transmitted to the rotating plate 9 through the connection, causing the rotating plate 9 to rotate together. During the rotation process, the rotating plate 9 divides the space inside the housing 1 into multiple material guide chambers. The material guide chambers are alternately connected to the input port 12 and the output port 13 as the rotating plate 9 rotates. When a material guide chamber is connected to the input port 12, the material enters the material guide chamber from the input port 12. When the material guide chamber is connected to the output port 13 as the rotating plate 9 continues to rotate, the material is discharged from the material guide chamber. After being discharged from the material guide chamber, the material enters the guide pipe 4. The guide pipe 4 is rotatably connected to the joint 11 on the lower surface of the housing 1. The protrusion at the lower end of the joint 11 is located on the guide pipe 4. The inside of the rotating groove 10 at the upper end allows the guide tube 4 to rotate relative to the shell 1 as needed under the shell 1, thereby adjusting the smooth discharge direction of the material. Under the guidance of the guide tube 4, the material is finally transported to the boiler combustion chamber. The discharge valve accurately controls the output amount and output speed of the material by controlling the start and stop and rotation speed of the motor 5. When the output amount of the material needs to be increased, the rotation speed of the motor can be increased; conversely, when the output amount of the material needs to be reduced, the rotation speed of the motor can be reduced or the motor can be stopped. However, when the inside of the shell 1 needs to be cleaned, the shell door 3 can be opened by the locking handle to expose the rotating shaft 8 and the rotating plate 9 for easy cleaning.

[0025] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
