Description

Technical Field

[0001] The utility model relates to the technical field of hydrometallurgy, in particular to an activated carbon loading and unloading device. Background Art

[0002] Activated carbon is widely used in the hydrometallurgical industry, both domestically and internationally, for oil removal because it effectively removes grease from solutions, ensuring smooth processing. However, after a period of use, activated carbon's adsorption capacity gradually decreases, necessitating the removal and packaging of the activated carbon from the canister. Failure to promptly replace the activated carbon canister compromises the oil removal process, ultimately impacting the quality of the entire metallurgical process. After removal, the activated carbon must be refilled with new activated carbon. However, existing activated carbon unloading and loading processes rely primarily on manual labor. The dust and waste generated during the replacement process can pollute the environment if not properly handled. Furthermore, the heavy physical labor required by workers in this harsh environment not only reduces efficiency but also creates difficult working conditions. Prolonged work in these conditions poses challenges to worker health and safety. In today's pursuit of efficient, large-scale production, the limitations of manual labor are becoming increasingly prominent, increasing labor costs and making it difficult to meet the continuity and stability requirements of modern industrial production. Utility Model Content

[0003] The utility model solves the deficiencies of the prior art and provides an activated carbon loading and unloading device which can prevent dust from being discharged, prevent pollution to the environment and greatly improve production efficiency.

[0004] To achieve the above-mentioned purpose, the utility model first proposes an activated carbon loading and unloading device, including a silo, a hopper and a fan. The silo is a sealed cavity, and the silo is provided with a feed port, a discharge port and an exhaust port. The discharge port is arranged at the bottom of the silo, and the exhaust port is arranged at the top of the silo. The discharge port of the hopper is connected to the inlet of the three-way valve, and the other inlet of the three-way valve is connected to the suction device. The outlet of the three-way valve is connected to the feed port of the silo through a pipeline, the air inlet of the fan is connected to the exhaust port of the silo through a pipeline, and the air outlet of the fan is connected to the air supply port of the guide pipe through a pipeline. The feed port of the guide pipe is connected to the discharge port of the silo, the outlet of the guide pipe is connected to the inlet of the gas-solid separation device, and the solid outlet of the gas-solid separation device is connected to the discharge pipe.

[0005] In this embodiment, a discharge device is installed on the discharge port of the silo, and the outlet of the discharge device is connected to the material guide pipe.

[0006] In this embodiment, the discharging device is a star-shaped discharger or a flap valve.

[0007] In this embodiment, the suction device includes a suction head and a hose, and the suction head is connected to the three-way valve through the hose.

[0008] In this embodiment, the gas outlet of the gas-solid separation device is connected to the dust removal device through a pipeline.

[0009] In this embodiment, the gas-solid separation device includes a three-way pipe body, and the solid outlet of the three-way pipe body is arranged below the gas outlet; specifically, a plurality of baffles are arranged in the three-way pipe body between the inlet and the gas outlet, so that the solid material hits the baffle and is decelerated and then falls into the solid outlet, thereby realizing solid-gas separation. Here, depending on the specific situation, the baffle can be set to multiple stages or single stage.

[0010] With the above structure, the utility model has the following advantages:

[0011] 1. This application can switch between loading and unloading. When loading new materials, activated carbon is manually added from the hopper, sucked into the silo by the fan, and unloaded through the discharging device under the silo; when unloading, the three-way valve is controlled to close the discharge port of the hopper, and the waste material in the activated carbon tank is extracted by the suction head. The waste pipe is directly sucked into the silo and unloaded through the discharging device under the silo. The cooperation of the hopper, suction device, fan and silo realizes efficient loading and unloading of activated carbon, thereby improving production efficiency.

[0012] 2. This application provides a gas-solid separation device at the final discharging part to separate the material and air, thereby improving the collection efficiency, reducing waste in the production process, and improving economic benefits.

[0013] 3. The silo of this application is equipped with a dust removal device. At the same time, the pipes connecting the hopper, silo and gas-solid separation device are all sealed, so as to prevent the discharge of dust and pollution to the environment while ensuring air tightness.

[0014] In summary, this device can complete the loading and unloading of activated carbon, prevent dust from being discharged, prevent pollution to the environment, and greatly improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1 、 2 As shown, an activated carbon loading and unloading device includes a silo 1, a hopper 2 and a fan 3. The silo 1 is a sealed cavity. The silo 1 is provided with a feed port, a discharge port and an air exhaust port. The bottom of the silo 1 is an inverted cone. The discharge port is provided at the bottom of the silo 1. A discharge device 4 is installed on the discharge port of the silo 1. In this embodiment, a pulse dust removal device is provided between the fan and the silo. The device has a back-blowing function and can blow off the dust on the diaphragm to ensure the normal use of the diaphragm. The air exhaust port is provided. It is placed on the top of the silo 1, the discharge port of the hopper 2 is connected to the inlet of the three-way valve 9, the other inlet of the three-way valve 9 is connected to the suction device 5, the outlet of the three-way valve 9 is connected to the feed port of the silo 1 through a pipeline, and the suction device 5 includes a suction head and a hose, and the suction head is connected to the three-way valve 9 through a hose; the pipelines connecting the hopper 2, the silo 1 and the gas-solid separation device 6 of this device are all sealed connections, so as to prevent the discharge of dust while ensuring air tightness, thereby preventing pollution to the environment.

[0021] The air inlet of the fan 3 is connected to the exhaust port of the silo 1 through a pipeline, the air outlet of the fan 3 is connected to the air supply port of the guide pipe 10 through a pipeline, the outlet of the discharging device 4 is connected to the guide pipe 10, the outlet of the guide pipe 10 is connected to the inlet of the gas-solid separation device 6, the solid outlet of the gas-solid separation device 6 is connected to the discharge pipe 7, and the gas outlet of the gas-solid separation device 6 is connected to the dust removal device 8 through a pipeline.

[0022] In this embodiment, the gas-solid separation device 6 includes a three-way tube body 61, the solid outlet of the three-way tube body 61 is arranged below the gas outlet, and multiple baffles 62 are arranged in the three-way tube body 61 between the inlet and the gas outlet. The baffles 62 are perpendicular to the flow direction of the incoming air, and there is a gap between adjacent baffles 62 to form a flow channel for the air flow to pass through; the air flow first hits the baffle 62 through the baffle 62, and the solid loses speed after the collision, and thus falls into the solid outlet under the action of gravity, while the gas is discharged along the gas outlet and enters the dust removal device 8 for further filtration and dust removal.

[0023] The working process of this device is as follows:

[0024] When new material is added, activated carbon is manually added from the hopper 2 and sucked into the silo 1 by the fan 3. The activated carbon is discharged through the discharge device 4 under the silo 1. At the same time, the air blown by the fan 3 blows the material discharged from the silo 1 along the guide pipe 10 into the gas-solid separation device 6 to separate the material and air. The solid material enters the activated carbon canister through the solid outlet of the gas-solid separation device 6, and the air is discharged from another channel (or enters the dust removal device 8);

[0025] During unloading, the three-way valve 9 is controlled to close the discharge port of the hopper 2, and the waste material in the activated carbon tank is extracted by the suction head. The waste material pipeline is directly sucked into the silo 1 and discharged through the discharge device 4 under the silo 1. At the same time, the wind blown by the fan 3 blows the material discharged from the silo 1 into the gas-solid separation device 6 along the guide pipe 10 to achieve the separation of material and air. The solid material enters the ton bag through the solid outlet of the gas-solid separation device 6 (for subsequent transportation), and the air is discharged from another channel (or enters the dust removal device 8).
