Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a matte furnace charge loosening machine. Background Art

[0002] A matte smelting furnace is a crucial piece of equipment used in the copper smelting process to convert copper sulfide concentrate into matte (copper-sulfur compound). Its primary function is to combine the copper and sulfur elements in the copper sulfide concentrate through a high-temperature smelting process to form matte, providing raw material for subsequent refining.

[0003] In the copper ore metallurgical process, the ore needs to be introduced into the copper furnace through a feeding mechanism. During the feeding process, the ore is often stuck in the feeding channel due to the different sizes of the copper ore, resulting in feeding obstruction. Therefore, the feeding channel needs to be loosened frequently. The existing loosening mechanism mostly uses a vibration motor, but the effect of the vibration motor is limited. For some large blockages, the loosening effect generated by the vibration of the motor is not obvious, and sometimes the machine has to be stopped to clear the blockage. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1As shown, the utility model provides a technical solution: a matte furnace charge loosening machine, comprising a feed bin 1, a feed box 2 is installed on one side of the feed bin 1, a feed port 3 is installed at the bottom of the feed box 2, a rotatable conveyor belt 4 is installed inside the feed box 2, and a conveyor partition 5 is provided on the conveyor belt 4, which is used to block the ore and prevent it from sliding.

[0023] like Figure 1 As shown, support frames 6 are respectively provided on both sides of the top of the feed bin 1, and a rotatable screw 7 is installed on the support frame 6. The screw 7 is driven by a first motor 8 located at the top of the support frame 6, and a lifting supporting plate 9 is installed between the screws 7 in threaded cooperation.

[0024] like Figure 1 As shown, a rotatable loosening rod 10 is installed in the middle of the supporting plate 9, and a gear ring 12 is sleeved on the top of the loosening rod 10. A second motor 11 is also provided on the supporting plate 9, and a gear 13 is installed at the output end of the second motor 11, which meshes with the gear ring 12.

[0025] like Figure 2 As shown, a protective cover 18 is installed on the top of the inner wall of the feed bin 1, and a locking cover 19 is hinged at the bottom of the protective cover 18. A clockwork spring 20 is provided at the hinge. The loosening rod 10 is located in the protective cover 18. The protective cover 18 is provided to protect the loosening rod 10 to prevent it from being contaminated by dust. When the loosening rod 10 is used, the loosening rod 10 moves downward to push open the locking covers 19 on both sides and extend them out of the protective cover 18. When stored, the loosening rod 10 automatically retracts into the protective cover 18, and the locking cover 19 automatically closes under the deformation of the clockwork spring 20.

[0026] like Figure 2 As shown, the loosening rod 10 is a hollow structure, and a rotary joint 14 and a high-pressure pump 15 are also provided on the top of the supporting plate 9. The rotary joint 14 is connected to the top of the loosening rod 10, and the high-pressure pump 15 is connected to the rotary joint 14 (certain sealing treatment is required).

[0027] like Figure 2 As shown, a cleaning brush 17 (bristle brush) is installed at the bottom of the loosening rod 10, and a spray hole 16 is opened at the bottom of the loosening rod 10, and the spray hole 16 and the cleaning brush 17 are staggered.

[0028] like Figure 2 As shown, a loosening head 101 is provided at the bottom of the loosening rod 10 , and the bottom of the loosening head 101 is in the shape of a pointed nose.

[0029] The discharge port of the feed bin 1 is connected to the feed port of the copper furnace (the copper furnace is not shown in the figure).

[0030] At the same time, the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0031] During use, the ore raw material enters the feed box 2 through the feed port 3, and the conveyor belt is driven by an external motor to rotate, thereby driving the ore to be transported. The ore then enters the feed bin 1 and enters the copper furnace through the feed bin 1.

[0032] When the quantity channel in the feed bin 1 is blocked, the first motor 8 is turned on to drive the screw 7 to rotate, and then drive the supporting plate 9 to descend, thereby driving the loosening rod 10 to descend to the feeding channel, and the loosening head 101 at the bottom of the loosening rod 10 hits the blocked ore, thereby shaking the ore off.

[0033] Furthermore, the second motor 11 is turned on to drive the gear 13 to rotate, and then the gear ring 12 and the loosening rod 10 are driven to rotate. The loosening head 101 rotates and strikes the ore downward, thereby quickly impacting the ore and making the channel unblocked.

[0034] For impurities such as dust adhering to the inner wall of the channel, turn on the high-pressure pump 15 and fill the interior of the loosening rod 10 with high-pressure airflow. The airflow is ejected through the injection hole 16 and directly impacts the inner wall of the channel, dispersing the adhered dust and other impurities. The dust can then be cleaned off with the cleaning brush 17.

[0035] To sum up, the matte furnace charge loosening machine is equipped with a lifting loosening rod, and the bottom of the loosening rod is equipped with a loosening head. The loosening head is driven to jump up and down in the feed bin by the up and down movement of the loosening rod, thereby loosening the blocked feed channel. Furthermore, the loosening rod can spray high-pressure airflow to eliminate dust and other impurities adhered to the inner wall of the feed channel. Combined with the brushing effect of the cleaning brush, it can ensure that the feed channel is unobstructed.

[0036] It should be noted that the electrical components appearing in this article are all connected to an external main controller and 220V or 380V mains electricity, and the main controller can be a conventional known device that controls a computer, etc. Its control principle, internal structure, and control switch mode are all conventional means of the prior art, which are directly quoted here without further elaboration. 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 terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device.
