Description

Technical Field

[0001] This utility model belongs to the technical field of quantitative feeder equipment, specifically relating to a quantitative feeder material interruption handling device. Background Technology

[0002] The side-blown smelting furnace is a strong oxidizing molten pool for matte smelting. At a high temperature of 1250-1350℃, copper sulfide concentrate and flux are smelted within the furnace. The primary air in the side-blown smelting furnace is process air with an oxygen concentration of 80%, primarily acting on the slag layer. If the feed supply from the batching system is interrupted, the primary tuyeres must be shut down and the furnace kept warm, severely impacting normal production. Therefore, ensuring a normal feed supply from the batching system is crucial for the stable operation and continuous production of the side-blown smelting furnace. However, in actual production, the metering feeder frequently experiences feed interruptions due to debris or large pieces of material clogging the discharge port or material overflow. Currently, manual handling is commonly used to address feeder interruptions, which is inefficient, labor-intensive, and poses certain safety hazards. Therefore, there is an urgent need for a device that can automatically or semi-automatically handle feeder interruption problems to improve production efficiency, reduce labor intensity, and eliminate safety hazards. Utility Model Content

[0003] This invention provides a material interruption handling device for a quantitative feeder to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A material interruption handling device for a quantitative feeder includes a steel bin, a vibrating hopper, a discharge port, a quantitative feeder, and a DCS control system. The vibrating hopper is connected below the steel bin, and the discharge port is connected below the vibrating hopper. The quantitative feeder is installed below the discharge port. The DCS control system is connected to the weighing device of the quantitative feeder and the signal of the vibrating hopper. When an abnormal material quantity is detected by the weighing device, the vibrating hopper is triggered to work to clear the material interruption.

[0006] Furthermore, the vibrating hopper and the steel silo are connected by a flexible connection.

[0007] Furthermore, the discharge port is equipped with an openable and closable door for manual handling of large pieces of blocked material.

[0008] Furthermore, one side of the movable door is connected to the edge of the discharge port via a fixed pin, and the other side is provided with a fixed sleeve, which can be connected to the positioning pin correspondingly provided on the edge of the discharge port.

[0009] Furthermore, the movable door and the vibrating hopper are respectively equipped with fixing rings and connected by anti-fall ropes.

[0010] The beneficial effects of this utility model are:

[0011] 1. By connecting the DCS control system with the weighing device of the quantitative feeder, automatic detection of material breakage and automatic start of the vibrating hopper are achieved without manual intervention, thus improving production efficiency.

[0012] 2. A flexible connection is used between the vibrating hopper and the steel silo, which reduces the impact of vibration on the steel silo and extends the service life of the equipment;

[0013] 3. The discharge port is equipped with an openable and closable movable door, which facilitates manual handling of large pieces of blocked material and improves processing efficiency;

[0014] 4. The movable door is detachably connected by a fixing pin, a fixing sleeve, and a positioning pin, which makes the structure simple, easy to operate, and safe and reliable;

[0015] 5. Fixing rings are installed on the movable door and the vibrating hopper respectively, and they are connected by anti-fall ropes to prevent the movable door from falling off accidentally, thus improving safety. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1As shown, a material shortage handling device for a quantitative feeder is characterized by comprising a steel bin 1, a vibrating hopper 2, a discharge port 3, a quantitative feeder 4, and a DCS control system 11. The steel bin 1 is used to store materials to be fed, such as copper sulfide concentrate or flux. The steel bin 1 can be made of carbon steel or composite materials, for example, carbon steel on the outside and stainless steel on the inside, to prevent material adhesion. The vibrating hopper 2 is located below the steel bin 1 to prevent material from sloshing inside the steel bin and to assist in material discharge. The steel bin 1 and the vibrating hopper 2 can be connected by a wear-resistant canvas, rubber flexible connection, or special flexible material to reduce the transmission of vibration generated by the vibrating hopper 2 during operation to the steel bin 1, protect the structure of the steel bin 1, and extend the service life of the equipment. The discharge port 3 is connected below the vibrating hopper 2 and is used to convey the material to the quantitative feeder 4.

[0022] The DCS control system 11 is used to automatically or manually activate the vibrating hopper 2 to assist material feeding when the quantitative feeder 4 experiences a material shortage or abnormal feeding. The DCS control system 11 has two working states: interlocked and non-interlocked. In the interlocked state, the DCS control system monitors the material weight signal fed back by the weighing device of the quantitative feeder 4 in real time based on a preset program. When an abnormal material quantity is detected, the DCS control system 11 automatically triggers the vibrating hopper 2 to start working, clearing the blockage, until the material quantity returns to normal or the set vibration time is reached. In the non-interlocked state, the DCS control system 11 decouples from the automatic association with the weighing signal of the quantitative feeder 4, and the operator can manually control the start and stop of the vibrating hopper 2 without being limited by the material quantity signal.

[0023] The movable door 6 is located at the discharge port 3 and is detachably connected to it. The movable door 6 facilitates clearing blockages when the discharge port is clogged. The movable door 6 is welded to the discharge port via two sets of fixing pins 5. Two fixing sleeves 7 are welded to the lower ends of the movable door 6, and two fixing sleeves 7 are correspondingly welded to both ends of the discharge port 3. Positioning pins 8 secure the two sets of fixing sleeves 7 in place. To prevent the movable door 6 from falling off and scratching the belt, a fixing ring 9 is welded to both the movable door 6 and the vibrating hopper 2. The two fixing rings 9 are connected by a fall arrest rope 10. During normal production, the movable door 6 is fixed with the positioning pins 8 to ensure the material layer thickness. If the quantitative feeder 4 experiences material overflow or blockage leading to a material interruption, the DCS control system 11 will automatically start the vibrating hopper 2 until the quantitative feeder restores its material flow. If the blockage is severe, the operator can remove the positioning pins of the movable door at the discharge port to manually resolve the blockage. After the quantitative feeder resumes normal material flow, the positioning pins of the movable door are restored.

[0024] In summary, this utility model provides a simple, easy-to-operate, safe and reliable quantitative feeder material interruption handling device. This device can effectively solve the material interruption problem of quantitative feeders, improve production efficiency, reduce labor intensity, eliminate safety hazards, and improve the stability of batching. Therefore, this device has good practicality.
