Description

Technical Field

[0001] This utility model relates to the field of weighing and unloading technology, specifically a weighing and unloading system. Background Technology

[0002] Materials require weighing and unloading during transportation or loading. However, existing technologies require multiple devices to work together during weighing and unloading, which not only increases costs but also makes the process cumbersome. Furthermore, existing technologies rarely include internal iron removal functions during weighing and unloading, so steel impurities mixed in with the materials can damage the casing and impeller, thus shortening the service life of the weighing and unloading system. Therefore, a new weighing and unloading system is needed. Utility Model Content

[0003] The purpose of this utility model is to provide a weighing and unloading system to solve the problem mentioned in the background art that the prior art requires multiple devices to work together and rarely has an internal iron removal system.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a weighing and unloading system, comprising a system frame, a weighing hopper fixed at the top of the system frame, a temporary storage hopper installed on the surface of the system frame and below the weighing hopper, and the inlet of the temporary storage hopper being connected to the outlet of the weighing hopper via a compensating flexible connecting pipe; a gas-material mixing chamber installed at the bottom of the system frame via a support frame, a circular discharge valve connected above the gas-material mixing chamber, and a communicating iron removal and air extraction chamber installed at the top of the circular discharge valve.

[0005] Preferably, a ladder is fixed to the surface of the system frame, which facilitates the maintenance of the entire system.

[0006] Preferably, a second butterfly valve is installed on the surface of the compensation flexible connector, which is used for controlling the material inside the compensation flexible connector.

[0007] Preferably, feeding covers are installed at both ends of the top of the weighing hopper, which are used for feeding materials into the weighing hopper.

[0008] Preferably, temporary storage covers are installed at both ends of the top of the temporary storage hopper, and the temporary storage covers are used for feeding the temporary storage hopper.

[0009] Preferably, a first butterfly valve is installed at the bottom of the weighing hopper, which is used for material control when the weighing hopper discharges material.

[0010] Preferably, a second transparent steel wire hose is installed at one end of the top of the iron removal extraction chamber via a solenoid valve.

[0011] Preferably, a first transparent steel wire hose is installed on the exhaust port of the round-mouth discharge valve via a solenoid valve.

[0012] Preferably, the first transparent steel wire hose and the second transparent steel wire hose are interconnected.

[0013] Preferably, the top of the iron removal extraction chamber is connected to the bottom of the temporary storage hopper via a third butterfly valve.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: When implementing this weighing and unloading system, the feeding cover is opened to add material into the weighing hopper. The material is weighed through the weighing hopper. After weighing, the first and second butterfly valves are opened, and the material enters the temporary storage hopper along the compensating flexible connection pipe, where it is buffered. Next, the third butterfly valve is opened, and the material enters the iron removal and extraction chamber for iron removal, reducing the damage of steel impurities to the casing and impeller. Then, it enters the round-mouth discharge valve, which discharges the material into the gas-material mixing chamber, and finally discharges it through the gas-material mixing chamber, thus completing the operation of the weighing and unloading system. This utility model, by setting up a weighing hopper, a temporary storage hopper, and a round-mouth discharge valve, achieves integrated processing functions for weighing, storing, and unloading. Simultaneously, the iron removal and extraction chamber enables iron removal from the material's interior, reducing the damage of steel impurities to the casing and impeller, and improving the service life of the weighing and unloading system.

The ladder 12 facilitates the maintenance of the entire system. A first butterfly valve 22 is installed at the bottom of the weighing hopper 2. The first butterfly valve 22 is used to control the material flow when the weighing hopper 2 discharges material. A temporary storage hopper 3 is installed on the surface of the system frame 1 and below the weighing hopper 2. The inlet of the temporary storage hopper 3 is connected to the outlet of the weighing hopper 2 through a compensating flexible connecting pipe 4. A second butterfly valve 5 is installed on the surface of the compensating flexible connecting pipe 4. The second butterfly valve 5 is used to control the material flow inside the compensating flexible connecting pipe 4. A feeding cover 21 and a temporary storage cover 31 are installed at the top ends of the weighing hopper 2 and the temporary storage hopper 3, respectively. The feeding cover 21 and the temporary storage cover 31 are used for feeding the weighing hopper 2 and the temporary storage hopper 3, respectively.

[0021] During implementation, the material is added to the weighing hopper 2 by opening the feeding cover 21. The material is weighed by the weighing hopper 2. After weighing, the first butterfly valve 22 and the second butterfly valve 5 are opened. The material enters the temporary storage hopper 3 along the compensation flexible connection pipe 4 and is then buffered inside the temporary storage hopper 3.

[0022] Furthermore, such as Figure 1 as well as Figure 3As shown, a gas-material mixing chamber 9 is installed at the bottom of the system frame 1 via a support frame 91. A round-mouth discharge valve 8 is connected above the gas-material mixing chamber 9. A metal removal and extraction chamber 7 is installed at the top of the round-mouth discharge valve 8.

[0023] During implementation, the third butterfly valve 6 is opened and the material enters the iron removal and extraction chamber 7 for iron removal to reduce the damage of steel impurities mixed in the material to the casing and impeller. Then it enters the round discharge valve 8 and is discharged into the gas-material mixing chamber 9 through the round discharge valve 8. Finally, it is discharged through the gas-material mixing chamber 9.

[0024] Working principle: When in use, first open the feeding cover 21 and add the material into the weighing hopper 2. The material is weighed by the weighing hopper 2. After weighing, open the first butterfly valve 22 and the second butterfly valve 5. The material enters the temporary storage hopper 3 along the compensation soft connection pipe 4 and is then buffered inside the temporary storage hopper 3.

[0025] Next, the third butterfly valve 6 is opened and the material enters the iron removal and extraction chamber 7 for iron removal to reduce the damage of steel impurities mixed in the material to the casing and impeller. Then it enters the round discharge valve 8 and is discharged into the gas-material mixing chamber 9 through the round discharge valve 8. Finally, it is discharged through the gas-material mixing chamber 9, thus completing the operation of the weighing and unloading system.

[0026] This utility model achieves integrated processing functions of weighing, storing and unloading materials by setting up a weighing hopper 2, a temporary storage hopper 3 and a round-mouth discharge valve 8; at the same time, the iron removal and air extraction chamber 7 realizes the function of removing iron from the inside of the material, so as to reduce the damage of steel impurities mixed in the material to the casing and impeller, and improve the service life of the weighing and unloading system.
