Description

Technical Field

[0001] This utility model relates to the field of transportation device technology, and in particular to a solid conveying device. Background Technology

[0002] Solid conveying devices are important equipment used in industrial production and logistics transportation to handle solid materials. In the chemical industry, many raw materials are usually in a solid state or sealed in solid phase devices. This method can effectively prevent the raw materials from reacting and deteriorating, and also facilitates the transportation of raw materials. However, general fixed conveying devices require human intervention during use, which affects the efficiency of solid conveying. At the same time, there is also the risk of injury to workers during human intervention, which reduces the safety of solid conveying operations. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a solid conveying device that improves the smoothness and convenience of the device's conveying operation, improves the overall efficiency of solid conveying operation, reduces human interference during solid conveying, and improves the safety of solid conveying operation.

[0005] According to the solid conveying device of this utility model, the upper surface of the conveyor belt entering the elevator is in contact with the elevator track, and a stopper is fixedly connected to the surface of the conveyor belt entering the elevator to prevent material from falling off.

[0006] According to the solid conveying device of this utility model, an oxygen content detector and a pressure gauge are fixedly connected to the surface of the buffer bin, and the detection ends of both the oxygen content detector and the pressure gauge extend into the interior of the buffer bin. This facilitates the monitoring of the internal conditions of the buffer bin and the moving feed bin.

[0007] According to the solid conveying device of this utility model, the buffer bin has a bucket-shaped structure, and a vibrator is fixedly connected to the lower end of the surface of the buffer bin. This improves the smoothness of material drop.

[0008] According to the solid conveying device of this utility model, a U-shaped buckle is fixedly connected to the surface of the valve opening mechanism. When transferring materials in the hopper, the U-shaped buckle contacts the feed inlet of the buffer hopper, thereby improving the smoothness of material transfer.

[0009] According to the solid conveying device of this utility model, the width of the first hopper support is smaller than the width of the second hopper support. This improves the identification effect.

[0020] Reference Figure 1-5 This utility model provides a solid conveying device, comprising: a bucket elevator shell 3; an elevator track 18 and an inlet conveyor belt 1 are fixedly connected to the lower end of the right surface of the bucket elevator shell 3; the upper surface of the inlet conveyor belt 1 contacts the elevator track 18; and a stopper 19 is fixedly connected to the surface of the inlet conveyor belt 1 to prevent objects from falling; a first roller shutter 2 is provided at the connection between the inlet conveyor belt 1 and the bucket elevator shell 3; an outlet conveyor belt 6 is fixedly connected to the upper end of the right surface of the bucket elevator shell 3; and a second roller shutter 5 is provided on the bucket elevator shell 3. The first roller shutter 2 and the second roller shutter 5 are used to control the amount of material entering the elevator.

[0021] Multiple buffer bins 8 are fixedly connected to the surface of the conveyor belt 6 of the elevator. Each buffer bin 8 is fixedly connected to an oxygen content detector 4 and a pressure gauge 12. The detection ends of both the oxygen content detector 4 and the pressure gauge 12 extend into the interior of the buffer bin 8. A vacuum tube 11, a gas supply pipe 10, and a vent pipe 9 are fixedly connected to the surface of the buffer bin 8. A weighing mechanism 22 and a pneumatic mechanism 14 are fixedly connected to the lower end of the buffer bin 8. The vacuum tube 11, the gas supply pipe 10, the vent pipe 9, and the pressure gauge 12 are used to detect and adjust the air pressure inside the buffer bin 8 and the moving hopper 23. The vacuum tube 11 is used to extract air from the buffer bin 8, the gas supply pipe 10 is used to replenish nitrogen to the buffer bin 8, and the weighing mechanism 22 is used to detect the total weight of the buffer bin 8 and the moving hopper 23. The buffer bin 8 has a bucket-shaped structure, and a vibrator 13 is fixedly connected to the lower end of the surface of each buffer bin 8. The vibrator 13 is used to improve the material dropping efficiency.

[0022] A movable hopper 23 is provided on the surface of the conveyor belt 1 of the elevator. When the device is in use, the movable hopper 23 is located above the buffer bin 8. The lower end of the movable hopper 23 is fixedly connected to a first hopper support 15 and a second hopper support 16. The width of the first hopper support 15 is smaller than the width of the second hopper support 16. The first hopper support 15 and the second hopper support 16 are used to improve the control group and improve the convenience of distinguishing different movable hoppers 23. The lower surface of the movable hopper 23 is fixedly connected to a discharge port 17. The discharge port 17 is provided with a valve opening mechanism 20. The surface of the valve opening mechanism 20 is fixedly connected to a U-shaped buckle 21. When transferring materials in the movable hopper 23, the U-shaped buckle 21 contacts the feed port of the buffer bin 8. The valve opening mechanism 20 cooperates with the U-shaped buckle 21 to improve the accuracy of the materials falling into the buffer bin 8 from the movable hopper 23.

[0023] Working Principle: By installing a PLC and an integrated touch screen, the PLC acts as the core control unit to control the operation of each device in the system. When the device feeds material into the buffer bin 8, the integrated touch screen sets the program and a material handling tool, such as a forklift, places the mobile bin 23 on the elevator conveyor belt 1. The stopper 19 is erected to prevent the mobile bin 23 from slipping. The material type is identified by the different widths of the support under the mobile bin 23 and the action of the limit switch, determining the buffer bin 8 to which the material belongs. Driven by the set program, the first roller shutter 2 opens, and the mobile bin 23 enters the elevator. Then, the second roller shutter 5 opens, and the mobile bin 23 enters the elevator conveyor belt 6. It moves to the top of the designated buffer bin 8, and the U-shaped buckle 21 in front of the valve opening mechanism 20 connects with the feed port at the top of the buffer bin 8. After the mobile bin 23 is opened, the material is smoothly released from the mobile bin 23 into the buffer bin 8.

[0024] During the feeding process, the oxygen content detector 4 monitors the oxygen content in the buffer chamber 8 in real time, and the pressure gauge 12 monitors the gas pressure in the buffer chamber 8 in real time. When the oxygen content is high, the interlock control of the vacuum tube 11 connected to the buffer chamber 8 is used to evacuate the vacuum, and nitrogen is replenished in time through the gas supply tube 10. If the pressure in the buffer chamber 8 is found to be high, the venting tube 9 is opened in time to release the pressure and maintain the pressure in the buffer chamber 8.

[0025] When the buffer bin 8 is discharging material normally, the pneumatic mechanism 14 opens the bottom discharge port of the buffer bin 8, the vibrator 13 vibrates the buffer bin 8 to quickly discharge material, the weighing mechanism 22 detects the weight of the material in the buffer bin 8, determines whether the required material has been completed, and closes the bottom discharge valve of the buffer bin 8 in time.
