Description

Technical Field

[0001] This utility model relates to the field of upward drawing furnace technology, and in particular to an upward drawing furnace for smelting copper. Background Technology

[0002] The upward drawing furnace is an important piece of equipment used for smelting copper. Its core process is the upward drawing method, which is mainly used to produce copper materials such as oxygen-free copper rods, copper tube billets, and profile billets. The metal block needs to be heated to a molten state in the upward drawing furnace, and then connected to the crystallizer through a vacuum device. The molten copper is drawn into the crystallizer from bottom to top, and after solidification, it forms a continuous casting billet.

[0003] When a metal block enters the upward drawing furnace for melting, it reacts with the high-temperature solution inside the furnace. The heat is rapidly transferred to the air and furnace walls, causing a sharp rise in local temperature. Consequently, a hot wave carrying waste gas and slag is ejected from the furnace opening. A dust collection device can clean up the waste gas and slag. For example, Chinese Patent Publication No. CN213701688U discloses a dust collection device for an upward drawing furnace, which includes a cutting table, legs connected to the lower surface of the cutting table, a copper busbar groove horizontally opened on the cutting table for placing copper busbars, a cutting motor above the cutting table, a cutting wheel connected to the rotating shaft of the cutting motor, a positioning block slidably arranged in the copper busbar groove in front of the copper busbar, the front side of the positioning block being rotatably connected to the rear end of a threaded adjusting rod, a rotating handle connected to the front end of the threaded adjusting rod, and an adjusting plate for the threaded adjusting rod to pass through on the cutting table. The adjusting plate has a threaded hole that mates with the adjusting plate. The dust collection device for an upward-drawing furnace provided by this utility model can fully contact the exhaust gas with the sprayed water, improve the contact effect between the exhaust gas and the sprayed water, and greatly improve the dust removal effect.

[0004] In actual operation, the spray head filters the used spray liquid through the filter screen set in the filter cylinder for repeated spraying. However, considering that the spray liquid contains tiny waste residues, it is difficult to ensure the filtration quality by relying solely on the filter screen. This cannot improve the filtration quality of the spray liquid. After long-term use, the water supply pipe or spray head is prone to clogging, resulting in poor practicality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that cannot improve the filtration quality of spray liquid, and to propose an upward drawing furnace for smelting copper.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an upward drawing furnace for smelting copper, including an upward drawing furnace and a dust collection unit placed on one side of the charging port of the upward drawing furnace. The dust collection unit includes a frame, and a dust removal chamber and a sealing chamber are formed inside the frame through a partition. A dust collection mechanism and a water dust removal mechanism are provided in the dust removal chamber.

[0008] The sealed cavity is equipped with a filter assembly, which is connected to the water dust removal mechanism and is used to filter the spray liquid inside the dust removal cavity.

[0009] Furthermore, the filter assembly includes a tank body, which is fixedly connected to the sealed cavity. Water supply pipes are connected to both the bottom and top of the tank body. The water supply pipes at both ends are respectively connected to the bottom of the dust removal cavity and the water dust removal mechanism. A top cover is fixedly connected to the top opening of the tank body by fasteners.

[0010] Furthermore, the filter assembly also includes a filter cylinder, which is slidably connected to the tank body. A cap is threadedly connected to the top opening of the filter cylinder, and the cap engages with a stop at the top of the tank body. Both the cap and the bottom of the filter cylinder are provided with water passage grooves.

[0011] Furthermore, a connecting rod is fixedly connected to the midpoint of the bottom of the cover, a pair of filter elements are movably inserted into the end of the connecting rod, and a placement box is movably inserted between the pair of filter elements. The end of the connecting rod is also inserted into the through hole at the midpoint of the bottom of the filter cylinder.

[0012] The placement box is equipped with an adsorption element inside. The placement box has a cylindrical structure, and baffles are detachably connected to both sides of the opening via an elastic structure.

[0013] Furthermore, the elastic structure includes protrusions, and at least one pair of protrusions are distributed around the periphery of the baffle, with the baffle located inside the protrusions to form corresponding deformation grooves;

[0014] The placement box has a relief groove on the inner wall of the openings on the upper and lower sides, which corresponds to the protrusion. The relief groove is connected to the outer wall of the placement box to form a slot.

[0015] Furthermore, the protrusion is provided with guide slopes on the upper and lower sides, the protrusion slides against the relief groove through the deformation groove, and the protrusion is also engaged in the slot through abutment deformation.

[0016] The present invention provides an upward drawing furnace for copper smelting, which has the following advantages: The present invention has a dust collection mechanism and a water dust removal mechanism inside the frame. The dust collection mechanism is used to collect the hot waves containing waste gas and slag sprayed from the upward drawing furnace mouth, which prevents the hot waves from affecting normal feeding and prevents the slag from splashing and affecting the processing environment. In addition, a filter cylinder is provided inside the tank, and a pair of filter cotton cores and at least one placement box containing adsorbent are also provided inside the filter cylinder. The filter cotton cores and adsorbent can further improve the filtration quality of the spray liquid. After long-term use, the baffle can be disassembled through the elastic structure to facilitate the cleaning and replacement of the adsorbent. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 An upward drawing furnace for smelting copper includes an upward drawing furnace 1 and a dust collection unit 2 placed on one side of the feeding port of the upward drawing furnace 1. The dust collection unit 2 includes a frame 21. A dust removal chamber 22 and a sealing chamber 23 are formed inside the frame 21 through a partition. A dust collection mechanism 3 and a water dust removal mechanism 4 are provided in the dust removal chamber 22.

[0025] The sealed cavity 23 is equipped with a filter assembly 5, which is connected to the water dust removal mechanism 4 and is used to filter the spray liquid inside the dust removal cavity 22.

[0026] In some embodiments, a support frame is installed on the top of the upward drawing furnace 1. The metal raw material is fed onto the support frame by a feeding mechanism, such as a mechanical gripper. When the metal raw material is placed in the upward drawing furnace, its heat will be rapidly transferred to the air and furnace wall inside the furnace, causing the local temperature to rise sharply. As a result, the upward drawing furnace opening will spray out a hot wave containing exhaust gas and slag. Therefore, a dust collection unit 2 is provided for dust collection and cleaning.

[0027] Furthermore, the dust collection unit 2 includes an exhaust fan and a dust collection pipe, both of which are connected to the dust removal chamber 22. The air inlet of the dust collection pipe is located next to the upper furnace 1.

[0028] Furthermore, the water dust removal mechanism 4 includes a circulating pump and multiple interconnected spray heads. The inlet of the circulating pump is connected to the water supply pipe 52, and its outlet is connected to the spray head. The waste residue in the exhaust gas is removed by spraying the spray liquid.

[0029] Furthermore, the filter assembly 5 includes a tank 51, which is fixedly connected to the sealed cavity 23. Water pipes 52 are connected to both the bottom and top of the tank 51. The water pipes 52 at both ends are respectively connected to the bottom of the dust removal cavity 22 and the water dust removal mechanism 4. A top cover 53 is fixedly connected to the top opening of the tank 51 by fasteners.

[0030] Specifically, a cover plate is hinged and rotated at the opening of the sealed cavity 23 on the frame 21. The tank 51 and the filter cartridge 54 are operated by opening and closing the cover plate. The fastener is a locking bolt, which fixes the tank 51 and the top cover 53. The sealing performance is further improved by sealing gaskets between the tank 51 and the top cover 53, as well as between the cover 55 and the stop part 511.

[0031] like Figure 3 The top of the top cover 53 has a protrusion, and the two ends of the protrusion are connected to the top cover 53 to form a through groove. After the top cover 53 is closed, the two ends of the through groove are connected to the tank body 51 and the water supply pipe 52 respectively to realize the function of conveying spray liquid. Of course, after the top cover 53 is closed, the top cover 53, together with the stop part 511, fixes the filter cylinder 54.

[0032] Furthermore, the filter assembly 5 also includes a filter cylinder 54, which is slidably connected inside the tank body 51. A cover 55 is threadedly connected to the top opening of the filter cylinder 54. The cover 55 is engaged with a stop 511 at the top of the tank body 51. Both the cover 55 and the bottom of the filter cylinder 54 are provided with water passage grooves 551.

[0033] Specifically, both the cap 55 and the filter cylinder 54 are columnar structures, and the diameter of the cap 55 is slightly larger than that of the filter cylinder 54. When the filter cylinder 54 is movably inserted into the tank body 51, the cap 55 is locked with the stop part 511, and the filter cylinder 54 is fixed under the action of the top cover 53.

[0034] More specifically, a connecting rod 56 is fixedly connected to the bottom midpoint of the cover 55, a pair of filter elements 57 are movably inserted into the end of the connecting rod 56, and a placement box 58 is movably inserted between the pair of filter elements 57. The end of the connecting rod 56 is also inserted into the through hole at the bottom midpoint of the filter cylinder 54.

[0035] The placement box 58 is equipped with an adsorption element inside. The placement box 58 has a cylindrical structure, and baffles 59 are detachably connected to both sides of the opening via elastic structures 6.

[0036] It is worth mentioning that the filter element 57 is a filter cotton core, and the adsorption element is an adsorption material such as activated carbon. The filter element 57 and the placement box 58 are respectively provided with at least one pair and at least one.

[0037] In general, the elastic structure 6 includes a protrusion 61, and at least one pair of the protrusions 61 are distributed around the periphery of the baffle 59. The baffle 59 is located inside the protrusion 61 to form a corresponding deformation groove 62.

[0038] The placement box 58 has a relief groove 63 on the inner wall of the openings on the upper and lower sides, which corresponds to the protrusion 61. The relief groove 63 is connected to the outer wall of the placement box 58 to form a slot 64.

[0039] Finally, the protrusion 61 is provided with guide slopes on the upper and lower sides, the protrusion 61 slides against the relief groove 63 through the deformation groove 62, and the protrusion 61 is also engaged in the slot 64 by the abutment deformation.

[0040] In this embodiment, both the placement box 58 and the baffle 59 are preferably made of materials with deformation capabilities such as rubber and plastic. Before installing the placement box 58, one of the baffles 59 is installed first, then the absorbent is filled in, and then the other baffle 59 is installed. Then the placement box 58 is plugged in and fixed. Of course, if one end of the placement box 58 is sealed, a baffle 59 can be provided.

[0041] In specific operation, the protrusion 61 slides against the guide slope and the deformation groove 62 and the relief groove 63. When the protrusion 61 is engaged in the groove 64, it recovers its deformation and then closes the end opening of the placement box 58. Similarly, after pressing the protrusion 61 to make it retract and disengage from the groove 64, the baffle 59 can be disassembled to clean and replace the adsorption component.

[0042] Working method: During operation, after fixing one of the baffles 59 to the opening of the placement box 58, after placing the adsorbent in the placement box 58, after fixing the other baffle 59, a pair of filter elements 57 and the placement box 58 are sequentially inserted into the connecting rod 56, and then the cover 55 is fixed to the filter cylinder 54 by means of threaded connection. Both the filter elements 57 and the placement box 58 are set inside the filter cylinder 54.

[0043] After the top cover 53 is closed, the dust collection mechanism 3 collects the exhaust gas and waste materials. Then, the circulation pump, together with the filter assembly 5 and the spray head, sprays the spray liquid. The spray liquid removes the waste residue in the exhaust gas, and the spray liquid can be recycled under the action of the filter assembly 5.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
