Description

Technical Field

[0001] This utility model belongs to the field of conveying equipment technology, specifically relating to a screw conveyor device for preventing blockage when feeding manganese tetroxide reactors. Background Technology

[0002] In the industrial production process of manganese tetroxide, the feed stage of the reactor typically uses a screw conveyor to quantitatively and continuously transport the raw materials. This device is one of the core pieces of equipment to ensure the continuity and stability of production.

[0003] Since manganese tetroxide is usually in powder form, there is a certain gap between the spiral blades and the feeding cylinder during the conveying process. The powder is easy to stick to the gap, making it impossible to convey. Long-term accumulation and adhesion can easily cause agglomeration. In addition, if the manganese tetroxide powder has a high humidity or the ambient air humidity is high, the powder is more viscous and agglomeration is likely to occur during the conveying process, causing some powder to be unable to be discharged from the discharge pipe. Utility Model Content

[0004] The purpose of this invention is to provide a screw conveyor device for preventing blockage of feed into a manganese tetroxide reactor, which can increase the flowability between powders, prevent powder materials from adhering to the inner wall of the feeding cylinder, and improve feeding efficiency.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] The anti-clogging screw conveyor for feeding manganese tetroxide reactor includes a feeding cylinder, which is inclined. A bracket is fixedly connected to the side wall of the feeding cylinder near the left side. A hopper is fixedly connected to the side wall of the feeding cylinder on the bracket. A discharge pipe is fixedly connected to the side wall of the feeding cylinder near the right side. A drive shaft is rotatably connected to the inner wall of the feeding cylinder. Spiral blades are fixedly connected to the side wall of the drive shaft. A motor is fixedly connected to the left end of the feeding cylinder. The output shaft of the motor is fixedly connected to the drive shaft. The drive shaft is a hollow structure. Several air outlets are opened on the side wall of the drive shaft. Each air outlet is equipped with a flow guiding component. An air inlet component is provided on the side wall of the feeding cylinder.

[0007] Furthermore, the airflow guiding assembly includes two movable plates disposed within the air outlet. The side walls of the movable plates are respectively fixedly connected to rotating shafts, and the other end of the rotating shafts is rotatably connected to the side wall of the air outlet. The two movable plates are hinged to a connecting plate on the side wall near the central axis of the drive shaft. The side walls of the connecting plates are fixedly connected to a fixing rod. A drive assembly is disposed within the drive shaft.

[0008] Furthermore, the drive assembly includes a telescopic rod disposed in the inner cavity of the transmission shaft, the other end of the fixed rod is fixedly connected to the telescopic rod, a support plate is fixedly connected to the end face of the feeding cylinder, an electric push rod is installed on the side wall of the support plate, a limit shell is fixedly connected to the telescopic end of the electric push rod, and the right end of the telescopic rod passes through the feeding cylinder and is rotatably connected to the limit shell.

[0009] Furthermore, the air inlet assembly includes a hot air blower fixedly installed on the end face of the feeding cylinder, a connecting pipe fixedly connected to the air outlet end of the hot air blower, a flow guide channel opened on the end face of the telescopic rod, multiple through holes opened on the side wall of the telescopic rod, and the other end of the connecting pipe communicating with the limiting shell.

[0010] Furthermore, the telescopic rod has an annular groove at one end inside the limiting shell, the flow channel is connected to the annular groove, and the connecting pipe is connected to the flow channel through the annular groove.

[0011] Furthermore, a protective shell is fixedly connected to the side wall of the drive shaft at the air outlet, and a breathable membrane is installed on the end face of the protective shell.

[0013] The technical effects achieved by this utility model are as follows:

[0014] The anti-clogging screw conveyor for feeding manganese tetroxide reactors of this invention utilizes the cooperation between the feeding cylinder, drive shaft, flow guide assembly, and drive assembly. By using the air outlet on the drive shaft and the flow guide assembly, the screw blades can easily blow the powder material during the feeding process. This increases the fluidity of the powder and prevents the powder material from adhering to the inner wall of the feeding cylinder. At the same time, the hot airflow generated by the hot air blower further increases the dryness of the powder, making it easier to discharge from the discharge pipe. Attached Figure Description

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-5 As shown, the anti-clogging screw conveyor for feeding manganese tetroxide reactor includes a feeding cylinder 1, which is inclined. A support 2 is fixedly connected to the side wall of the feeding cylinder 1 near the left side. A hopper 3 is fixedly connected to the side wall of the feeding cylinder 1 on the support 2. A discharge pipe 4 is fixedly connected to the side wall of the feeding cylinder 1 near the right side. A drive shaft 5 is rotatably connected to the inner wall of the feeding cylinder 1. Spiral blades 6 are fixedly connected to the side wall of the drive shaft 5. A motor 23 is fixedly connected to the left end of the feeding cylinder 1. The output shaft of the motor 23 is fixedly connected to the drive shaft 5. The drive shaft 5 is a hollow structure. Several air outlets 7 are opened on the side wall of the drive shaft 5. Each air outlet 7 is equipped with a flow guiding component. An air inlet component is provided on the side wall of the feeding cylinder 1.

[0024] like Figure 3 and Figure 4 As shown, the flow guiding assembly includes two movable plates 8 disposed in the air outlet 7. The side walls of the movable plates 8 are respectively fixedly connected to rotating shafts 9. The other end of the rotating shafts 9 is rotatably connected to the side wall of the air outlet 7. The two movable plates 8 are hinged to the side wall near the central axis of the drive shaft 5 with connecting plates 10. The side walls of the connecting plates 10 are fixedly connected to fixing rods 11. The drive shaft 5 is provided with a drive assembly.

[0025] During the swinging process, the movable plate 8 can discharge hot air over a wide area and blow out the area between the spiral blades 6, blowing up some powder material. The materials collide with each other, which can effectively prevent them from adhering to the inner wall of the feeding cylinder 1 and causing clumping.

[0026] like Figure 1 and Figure 5As shown, the drive assembly includes a telescopic rod 14 disposed in the inner cavity of the drive shaft 5, and the other end of the fixed rod 11 is fixedly connected to the telescopic rod 14. A support plate 17 is fixedly connected to the end face of the feeding cylinder 1, and an electric push rod 18 is installed on the side wall of the support plate 17. The telescopic end of the electric push rod 18 is fixedly connected to a limit shell 19, and the right end of the telescopic rod 14 passes through the feeding cylinder 1 and is rotatably connected to the limit shell 19.

[0027] The electric push rod 18 can be replaced with a cylinder according to application requirements to realize reciprocating telescopic motion and control the swing of the movable plate 8. The telescopic rod 14 is rotatably connected to the limiting shell 19. When the drive shaft 5, the spiral blade 6 and the telescopic rod 14 rotate, there will be no motion interference and the air intake of the connecting pipe 22 will not be affected. In addition, the telescopic rod 14 and the inner wall of the drive shaft 5 adopt a sliding connection of slider and groove, which can realize telescopic movement and rotation at the same time.

[0028] like Figure 1 , Figure 4 and Figure 5 As shown, the air inlet assembly includes a hot air blower 21 fixedly installed on the end face of the feeding cylinder 1. A connecting pipe 22 is fixedly connected to the air outlet end of the hot air blower 21. A guide channel 16 is opened on the end face of the telescopic rod 14. Multiple through holes 15 are opened on the side wall of the telescopic rod 14. The other end of the connecting pipe 22 is connected to the limiting shell 19.

[0029] The principle and structure of the hot air blower 21 are existing mature technologies and will not be described in detail in this solution. The hot air flow generated by the hot air blower 21 can maintain the dryness of the powder raw materials and reduce the moisture content. By maintaining the dryness of the raw materials, the purpose of preventing agglomeration and adhesion can be achieved.

[0030] like Figure 5 As shown, the telescopic rod 14 has an annular groove 20 at one end inside the limiting shell 19. The guide channel 16 is connected to the annular groove 20, and the connecting pipe 22 is connected to the guide channel 16 through the annular groove 20. The annular groove 20 facilitates the introduction of hot air into the guide channel 16, and the telescopic rod 14 does not affect the intake of hot air during rotation.

[0031] like Figure 4 As shown, protective shells 24 are fixedly connected to the side wall of the drive shaft 5 at the air outlet 7, and a breathable membrane 25 is installed on the end face of the protective shell 24.

[0032] To prevent material from entering the inner cavity of the drive shaft 5 through the air outlet 7, a breathable membrane 25 is provided at the end of the air outlet 7. This membrane can shield the powder material without affecting the airflow. When the airflow blows out, it can also blow off the material adhering to the breathable membrane 25, making it highly practical.

[0033] like Figure 3As shown, two support plates are fixedly connected to the end of the movable plate 8 near the fixed rod 11. The side wall of the support plate has an elongated hole 13. A pin 12 is fixedly connected to the side wall of the connecting plate 10, and the pin 12 is inserted into the elongated hole 13. When the fixed rod 11 drives the movable plate 8 to swing through the connecting plate 10, the cooperation between the pin 12 and the elongated hole 13 can eliminate the motion interference problem caused by the arc motion.

[0034] The working principle of this utility model is as follows: First, the feeding pipe 4 is connected to the feeding pipe on the reactor. Then, manganese tetroxide powder is fed into the hopper 3, and the motor 23, electric push rod 18 and hot air blower 21 are started. The output shaft of the motor 23 drives the spiral blades 6 to rotate through the transmission shaft 5. The spiral blades 6 push the powder material. The hot air generated by the hot air blower 21 enters the guide channel 16 through the connecting pipe 22 and is blown out from the through hole 15. Then it is blown into the feeding cylinder 1 from the air outlet 7, which can increase the fluidity of the powder raw material and reduce the probability of it adhering to the inner wall of the feeding cylinder 1.

[0035] At the same time, the electric push rod 18 drives the telescopic rod 14 to reciprocate and extend. The telescopic rod 14 drives the connecting plate 10 to reciprocate through the fixed rod 11. The connecting plate 10 drives the movable plate 8 to swing around the rotating shaft 9, expanding the flow range of hot air and further improving the feeding efficiency.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
