Description

Technical Field

[0001] The utility model relates to the field of non-ferrous metal smelting, in particular to a pulverized coal bag cutting device. Background Technique

[0002] Pulverized coal is widely used as a reducing agent in the copper smelting industry. When purchasing pulverized coal, it is packed in ton bags, which are relatively large in both quality and volume. During transportation in the workshop, it is lifted by a gantry crane to the injection port of the pulverized coal tank, and the tying rope of the ton bag is manually untied and poured into the pulverized coal tank bin.

[0003] During the process of manually injecting pulverized coal, a worker is required to untie the tying rope at the discharge port of the ton bag. There is often a large amount of dust when opening the bag, and during the process of injecting pulverized coal, a large amount of pulverized coal also overflows when the worker pours the pulverized coal into the pulverized coal tank. Therefore, a new type of pulverized coal bag cutting device is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems raised in the background technique, and a pulverized coal bag cutting device is designed.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows: a pulverized coal bag cutting device, including an external suspension rod, a ton bag, a cutter, a pulverized coal tank, a pulverized coal conveyor, an extension fixing seat, a fixing block, a mounting seat, a cutting edge, a mounting frame, a fixing groove, a tool rest, and a dust shield. The internal of the pulverized coal tank is in an inverted cone shape. A dust shield is provided at the top of the pulverized coal tank. A square hole is opened below the dust shield. The square hole is provided with an extension fixing seat. Four fixing blocks are distributed in a square on the extension fixing seat. A cutter is installed on the extension fixing seat. The bottom end of the pulverized coal tank is a pulverized coal conveyor.

[0006] Preferably, the cutter includes a tool rest, a mounting seat, a cutting edge, a mounting frame, and a fixing groove. The cutter has four tool rests. The mounting seat is fixedly installed on the tool rest. The cutting edge is installed in the mounting seat. The bottom end of the tool rest is a mounting frame. The fixing groove is opened in the mounting frame.

[0007] Preferably, above the dust shield is a feed inlet. The ton bag enters above the feed inlet. The ton bag is transported to above the feed inlet through the external suspension rod.

[0008] Preferably, the external suspension rod is a robotic arm or a hoisting device equipped by the factory.

[0009] Beneficial Effects:

[0010] The utility model provides a pulverized coal bag cutting device, which has the following beneficial effects. Through its structural design, by using the self-gravity when the ton bag descends, after the ton bag enters the dust baffle, the cutter directly cuts open the bottom of the ton bag. After the bottom of the ton bag is cut, a "V-shaped" cutting opening appears, enabling the pulverized coal to be filled into the pulverized coal tank through the cutting opening. The dust baffle and the uncut part of the ton bag can also seal the feeding port, reducing the overflow of pulverized coal, and at the same time, the work of manually untying the discharging port can be saved.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0018] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "set / sleeved with", "socketed connection", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution: a pulverized coal bag cutting device, including an external suspension rod 1, a ton bag 2, a cutter 3, a pulverized coal tank 4, a pulverized coal conveyor 5, an extended fixing seat 6, a fixing block 7, a mounting seat 8, a cutting edge 9, a mounting frame 10, a fixing groove 11, a tool holder 12, and a dust baffle 13. The inside of the pulverized coal tank 4 is in an inverted conical shape. A dust baffle 13 is provided at the top of the pulverized coal tank 4. A square hole is opened below the dust baffle 13. The extended fixing seat 6 is provided in the square hole. Four fixing blocks 7 are distributed in a square on the extended fixing seat 6. The cutter 3 is installed on the extended fixing seat 6. The bottom end of the pulverized coal tank 4 is a pulverized coal conveyor 5. The cutter 3 includes a tool holder 12, a mounting seat 8, a cutting edge 9, a mounting frame 10, and a fixing groove 11. The cutter 3 has four tool holders 12. The mounting seat 8 is fixedly installed on the tool holder 12. The cutting edge 9 is installed inside the mounting seat 8. The bottom end of the tool holder 12 is a mounting frame 10. The fixing groove 11 is opened inside the mounting frame 10. Above the dust baffle 13 is a feed inlet 14. The ton bag 2 enters above the feed inlet 14. The ton bag 2 is transported above the feed inlet 14 through the external suspension rod 1. The external suspension rod (1) is a robotic arm or a hoisting device equipped by the factory.

[0020] Through the personnel in the art, all the electrical components in this case are connected to their adapted power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, reference should be made to the sequence of the electrical components working successively in the following working principle to complete the electrical connection. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of the electrical control will be made.

[0021] In this implementation scheme:

[0022] During operation, first, the external hanging rod 1 hoists the ton bag 2 to the feeding port 14. Then, the external hanging rod 1 releases the ton bag 2, and under the action of its own gravity, the ton bag 2 enters the dust shield 13 through the feeding port 14. The cutter 3 directly cuts the bottom of the ton bag 2. After the bottom of the ton bag 2 is cut, a "V-shaped" cut is formed, allowing the pulverized coal to be filled into the pulverized coal tank 4 through the cut. Then, the pulverized coal is conveyed to the required position through the pulverized coal conveyor 5. When the cutter 3 needs to be maintained or replaced, the worker or the robotic arm only needs to grasp the tool holder 12 and lift it upward to separate the fixing groove 11 in the mounting bracket 10 from the fixing block 7 on the extended fixing seat 6 to complete the disassembly. After the disassembly, a series of cleaning and maintenance work can be carried out by replacing the cutting edge 9 on the mounting seat 8.

[0023] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation. An element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
