Description

Technical Field

[0001] This utility model relates to the field of filling column filling, and in particular to a feed valve for a filling column filling device. Background Technology

[0002] In industrial production, especially in industries such as pharmaceuticals, chemicals, and food, the filling process of packed columns places extremely high demands on the accuracy and stability of material conveying.

[0003] Traditional feed valves have many problems in practical applications. For example, materials are prone to clogging at the valve, and for powdery or fluid materials, they are prone to adhering to the inner wall. Since the existing valve components are all fixed installations, disassembly is cumbersome and subsequent cleaning is troublesome.

[0004] Therefore, it is necessary to propose a feed valve for a filling column filling device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a feed valve for a filling column filling device to solve many problems of traditional feed valves in practical applications, such as the easy blockage of materials at the valve, and the easy adhesion of powdery or fluid materials to the inner wall. Since the existing valve components are all fixed installations, disassembly is cumbersome and subsequent cleaning is troublesome.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feed valve for a filling column filling device, comprising:

[0007] Conveyor bucket;

[0008] Valve assembly, the valve assembly being installed inside the conveying hopper;

[0009] The valve assembly includes a baffle, a rotating plate is rotatably connected inside the baffle, and a fan is embedded in the top of the rotating plate;

[0010] The rotating plate has output ports at both ends, and a cavity is formed inside the rotating plate. The air outlet of the fan is connected to the cavity, and both output ports are connected to the cavity.

[0011] Preferably, a rubber pad is fixed to the end of each of the two output ports, and a through groove corresponding to the output port is opened in the middle of the rubber pad;

[0012] The baffle has a square opening inside for the rotating plate to pass through, and the rubber pad is attached to the inner wall of the square opening.

[0013] Preferably, a vibration motor is fixed inside the baffle.

[0014] Preferably, a connecting frame is connected to the top of the conveying bucket, a passage groove for a baffle to pass through is opened on one side of the connecting frame, and a cylinder is connected to one side of the connecting frame.

[0015] Preferably, a fixing frame is fixed to one side of the baffle, and a drive motor is fixedly connected inside the fixing frame;

[0016] Both sides of the rotating plate are fixed with rotating shafts, and the two rotating shafts are respectively rotatably connected to the inner wall of the square opening. The drive shaft of the drive motor is fixedly connected to one of the rotating shafts.

[0017] Preferably, the bottom end of the conveying hopper is connected to a conveying pipe, and an electric heating tube is wound around the outside of the conveying pipe.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. Rotating shafts are fixed on both sides of the rotating plate. The two rotating shafts are rotatably connected to the inner wall of the square opening, and the drive shaft of the drive motor is fixedly connected to one of the rotating shafts, so that the rotating plate can rotate stably inside the baffle to realize the opening and closing and adjustment of the material channel.

[0020] 2. Furthermore, as the rotating plate rotates with the drive motor, the angle of the rotating plate within the baffle can be changed, thereby adjusting the width of the output channel when the material is discharged downwards, which is used to control the falling speed of the material and buffer the material.

[0021] 3. At the same time, after the material output is completed, the blower can be started. The drive motor drives the rotating plate to rotate, so that one end of the rotating plate faces the inner wall of the conveying hopper. The wind generated by the blower can blow towards the inner wall, blowing down the material that is stuck to the inner wall to avoid sticking. In addition, the drive motor can drive the rotating plate to rotate continuously, hitting the output material and reducing the phenomenon of material clumping. Attached Figure Description

[0025] This utility model provides, for example Figures 1-2 The feed valve shown is for a filling device for a filling column, comprising:

[0026] Conveying hopper 1, as one of the main parts of the entire feed valve, is mainly used to hold the material to be filled and provide material reserves for the subsequent conveying process.

[0027] The valve assembly is installed inside the conveyor hopper 1 and is used to control whether the material can be discharged downwards, serving to open and close the conveyor hopper 1.

[0028] The valve assembly includes a baffle 3, a rotating plate 8 is rotatably connected inside the baffle 3, a fan 9 is embedded in the top of the rotating plate 8, output ports 10 are opened at both ends of the rotating plate 8, a cavity is opened inside the rotating plate 8, the air outlet of the fan 9 is connected to the cavity, and both output ports 10 are connected to the cavity.

[0029] The top of the conveyor bucket 1 is connected to a connecting frame 2. A passage groove for the baffle 3 to pass through is opened on one side of the connecting frame 2. A cylinder 4 is connected to one side of the connecting frame 2.

[0030] A fixing frame 6 is fixed on one side of the baffle 3, and a drive motor 7 is fixedly connected inside the fixing frame 6;

[0031] In the actual operation of this utility model, the function of the drive motor 7 is to provide power for the rotation of the rotating plate 8. Its drive shaft is fixedly connected to one of the rotating shafts of the rotating plate 8, so that the drive motor 7 can accurately control the rotation angle and speed of the rotating plate 8.

[0032] The retraction of cylinder 4 can pull the entire baffle 3 out of the connecting frame 2, making it easier to open the entire conveying bucket 1 and also making it easier for personnel to clean and maintain the baffle 3, thus improving the service life of the equipment.

[0033] Rotating plates 8 are fixed with rotating shafts on both sides. The two rotating shafts are rotatably connected to the inner wall of the square opening, and the drive shaft of the drive motor 7 is fixedly connected to one of the rotating shafts, so that the rotating plates 8 can rotate stably within the baffle 3, realizing the opening and closing and adjustment of the material channel.

[0034] Furthermore, as the rotating plate 8 rotates with the drive motor 7, the angle of the rotating plate 8 within the baffle 3 can be changed, thereby adjusting the width of the output channel when the material is discharged downwards, which is used to control the falling speed of the material and buffer the material.

[0035] At the same time, after the material output is completed, the blower 9 can be started, and the drive motor 7 can be used to drive the rotating plate 8 to rotate, so that one end of the rotating plate 8 faces the inner wall of the conveying bucket 1. The wind generated by the blower 9 can blow towards the inner wall, blowing down the material that is stuck to the inner wall and avoiding sticking.

[0036] In addition, the drive motor 7 can drive the rotating plate 8 to rotate continuously, striking the output material and reducing the phenomenon of material clumping.

[0037] Both output ports 10 are fixed with rubber pads 11 at their ends. The rubber pads 11 have through grooves in the middle that correspond to the output ports 10, so that the rubber pads 11 can fit against the inner wall and avoid gaps.

[0038] The baffle 3 has a square opening inside for the rotating plate 8 to rotate through, and the rubber pad 11 is attached to the inner wall of the square opening.

[0039] A vibration motor 12 is fixed inside the baffle 3. By generating vibration, the material is prevented from clumping or blocking inside the baffle 3, thus ensuring the smooth flow of the material.

[0040] The bottom end of the conveying hopper 1 is connected to a conveying pipe 5. An electric heating tube is wound around the outside of the conveying pipe 5. The electric heating tube can heat the material inside the conveying pipe 5 to prevent the material from condensing or becoming less fluid due to low temperature, ensuring that the material can complete the filling process smoothly. If necessary, a protective cover can be installed on the outside of the electric heating tube to ensure that the heat is not lost.
