Description

Technical Field

[0001] This utility model relates to the field of lead melting technology, specifically to a lead melting furnace cover device. Background Technology

[0002] A lead melting furnace is a device that can melt lead ingots to obtain molten lead. The molten lead obtained from the lead melting furnace can be used to manufacture lead-acid battery grids, cable sheathing, etc. Therefore, lead melting furnaces are widely used in the battery industry and lead extrusion industry.

[0003] There are many existing technologies involving lead melting furnaces. For example, patent document CN118208950A discloses an energy-saving lead melting furnace. This furnace includes a furnace body and a cover plate fixed to the furnace body. The cover plate is an integral structure and is equipped with baffles and guide plates. This cover plate structure can divide the interior of the furnace body into different functional areas and also has a heat preservation function. However, careful analysis reveals that this lead melting furnace still has the following technical problems:

[0004] 1. The lead melting furnace uses the first and second baffles to statically stir the molten lead, making the molten lead more uniform. However, due to the lack of dynamic stirring, impurities cannot float on the surface of the liquid, resulting in poor slag removal.

[0005] 2. During the lead melting process, it is necessary to observe the liquid level and impurities inside the lead furnace in real time, and to remove slag in a timely manner to improve the quality of the lead melt. However, the cover plate of the lead melting furnace is an integral structure, and the cover plate is quite heavy. As a result, when it is necessary to observe and remove slag, the furnace body can only be opened by lifting the entire cover plate. Therefore, there is a technical problem that the furnace body cannot be opened quickly and conveniently for observation and slag removal.

[0006] Therefore, it is necessary to provide a new cover plate structure to solve the above-mentioned technical problems. Utility Model Content

[0007] To overcome the aforementioned technical problems in the prior art, this utility model provides a lead melting furnace cover device. This cover device is suitable for lead melting furnaces with an internal heat preservation zone, a stirring zone, and a melting zone. It is designed with covers that facilitate the opening and closing of the heat preservation zone, stirring zone, and melting zone, and is equipped with a liquid level measuring component and a stirring component. In actual use, on the one hand, impurities can be floated on the liquid surface by stirring to achieve effective slag removal; on the other hand, it also enables the lead melting furnace to quickly open the heat preservation zone, stirring zone, and melting zone for real-time observation and slag removal. This solves the technical problems of existing lead melting furnaces being unable to effectively remove slag and unable to quickly and conveniently open the furnace cover for observation and slag removal.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A lead melting furnace cover device includes a cover seat for fixing to the furnace body. The cover seat has a reinforcing beam integrally formed in the middle, dividing the cover seat into a front half and a rear half. The front half of the cover seat has, from left to right, a liquid level measuring component for extending into the heat preservation zone inside the furnace body, a stirring component for extending into the stirring zone inside the furnace body, and a right front hole communicating with the melting zone inside the furnace body. The rear half of the cover seat has a left rear hole communicating with the heat preservation zone, a middle rear hole communicating with the stirring zone, and a right feed notch communicating with the melting zone. Heat preservation cover plates are hinged to the cover seat and respectively cover the right front hole, the left rear hole, and the middle rear hole. A gantry frame is fixed on the reinforcing beam. A cylinder connected to each heat preservation cover plate is installed on the gantry frame. When the cylinder extends or retracts, it can control the opening or closing of the corresponding heat preservation cover plate.

[0010] The front half of the cover is provided with through holes for communicating with the heat preservation zone and the stirring zone. A mounting plate is fixed above the through holes by bolts, and the liquid level measuring component and the stirring component are respectively fixed on the mounting plate.

[0011] Symmetrical and vertically connected stiffening plates are fixed to the two sides of the right front hole, the two sides of the left rear hole, the two sides of the middle rear hole, and the two sides of each through hole. Each insulation cover plate and each mounting plate are located between the stiffening plates.

[0012] The two ends of the gantry frame are respectively fixed to the two ends of the reinforcing beam by bolts.

[0013] Two lifting rings are fixed at each end of the reinforcing beam, and the two lifting rings are located on both sides of the reinforcing beam.

[0014] Each of the reinforcing beams is fixed with a hinge seat, and each insulation cover plate is mounted on the cover seat via the hinge seat.

[0015] The four corners of the cover are respectively fixed with pins for insertion into the upper part of the furnace body.

[0016] A protective cover for covering the right feed opening is fixed on the cover.

[0017] The advantages of using this utility model are:

[0018] 1. This utility model is particularly suitable for lead melting furnaces whose internal structure includes a heat preservation zone, a stirring zone, and a melting zone. It features covers for easy opening and closing of these zones, as well as a liquid level measuring component and a stirring component. In actual use, stirring ensures uniform mixing of the molten lead and causes impurities to float to the surface, facilitating effective slag removal. The opening and closing of the heat preservation cover is controlled by a cylinder, allowing for convenient and rapid opening and closing of the heat preservation zone, stirring zone, and melting zone. This facilitates real-time observation and slag removal of each functional zone during lead melting, simplifying the opening and closing process and improving the quality of the molten lead, thus enhancing its practicality.

[0019] In addition, this utility model fixes both the liquid level measuring component and the stirring component on the cover, making the liquid level measuring component and the stirring component and the cover a whole structure. In actual application, it is only necessary to fix the cover to the furnace body to realize the fixed installation of the liquid level measuring component and the stirring component, which is more convenient to use and more practical.

[0020] Compared to existing lead melting furnaces, this invention allows for quick and convenient opening of the insulation cover plate via a cylinder without lifting it off the cover base, enabling observation and slag removal of each functional area. This facilitates real-time observation and slag removal, and also helps ensure the stability and reliability of lead ingot melting.

[0021] 2. The reinforcing ribs of this utility model help to enhance the structural strength of the cover seat, which can effectively prevent the cover seat from breaking during use.

[0022] 3. This new invention fixes the gantry frame to the reinforcing beam, which helps to improve the stability of the gantry frame on the cover, thereby making the opening and closing of the insulation cover plate more stable and reliable.

[0023] 4. This utility model uses a lifting ring to facilitate the overall lifting and opening of the upper cover device as needed, making the overall movement of the upper cover device more convenient.

[0024] 5. This utility model uses a pin to quickly and stably fix the upper cover device to the furnace body, which helps to prevent the cover from sliding on the furnace body.

[0025] 6. This utility model, through its protective cover, not only helps to ensure the accuracy and reliability of feeding, but also helps to prevent external objects from accidentally falling into the furnace body, thus improving the safety of use. Attached Figure Description

Protective cover. Detailed Implementation

[0033] like Figure 1-4 As shown, this utility model provides a cover device for a lead melting furnace, which includes a cover seat 2 for fixing to the furnace body 1. The cover seat 2 has a cuboid structure, and pins 16 are fixed to the four corners of the cover seat 2. The cover seat 2 can be fixed to the furnace body 1 by the pins 16, thereby preventing the cover seat 2 from sliding. A reinforcing beam 6 is integrally formed in the middle of the cover seat 2, dividing the cover seat 2 into a front half and a rear half. The reinforcing beam 6 protrudes from the upper surface of the cover seat 2, and its length can be the same as the length of the cover seat 2 or slightly shorter than the length of the cover seat 2. The front half of the cover 2 is provided from left to right with a liquid level measuring component 8 for extending into the heat preservation zone 3 inside the furnace body 1, a stirring component 9 for extending into the stirring zone 4 inside the furnace body 1, and a right front hole communicating with the melting zone 5 inside the furnace body 1. The rear half of the cover 2 is provided with a left rear hole communicating with the heat preservation zone 3, a middle rear hole communicating with the stirring zone 4, and a right feed notch 7 communicating with the melting zone 5. Heat preservation cover plates 10 are hinged on the cover 2 and respectively cover the right front hole, the left rear hole, and the middle rear hole. In addition, a gantry frame 11 is fixed on the reinforcing beam 6. A cylinder (not shown in the figure) is installed on the gantry frame 11 and is connected to each heat preservation cover plate 10. The number of cylinders is the same as or greater than the number of heat preservation cover plates 10. One end of each cylinder is hinged to the gantry frame 11, and the other end of each cylinder is hinged to the heat preservation cover plate 10. By controlling the extension and retraction of the cylinder, the corresponding insulation cover 10 can be opened or closed, thereby enabling the insulation zone 3, stirring zone 4 and melting zone 5 to be opened or closed quickly and easily. This not only facilitates real-time observation of the lead melting process, but also facilitates real-time slag removal.

[0034] In a specific embodiment, such as Figure 1-4 As shown, the front half of the cover 2 is provided with through holes for communicating with the heat preservation zone 3 and the stirring zone 4. An mounting plate 12 is fixed above the through holes by bolts. The mounting plate 12 covers the through holes. The liquid level measuring component 8 and the stirring component 9 are fixed on the mounting plate 12.

[0035] In this embodiment, by fixing both the liquid level measuring component 8 and the stirring component 9 onto the cover 2, the liquid level measuring component 8 and the stirring component 9 are integrated with the cover 2. In practical applications, it is only necessary to fix the cover 2 onto the furnace body 1 to achieve the fixed installation of the liquid level measuring component 8 and the stirring component 9, which is more convenient to use and more practical.

[0036] It should be noted that the shape and size of the mounting plate 12 can be the same as those of the insulation cover plate 10. In addition, the liquid level measuring component 8 and the stirring component 9 mentioned above are existing conventional technologies and will not be described in detail.

[0037] Since the cover 2 is usually a casting and has a large area, in order to prevent the cover 2 from breaking during use, this embodiment has symmetrical and vertically connected stiffening plates 13 fixed on both sides of the right front hole, both sides of the left rear hole, both sides of the middle rear hole and both sides of each through hole, and the insulation cover plate 10 and each mounting plate 12 are respectively located between the stiffening plates 13. This can effectively improve the structural strength of the cover 2 and achieve the purpose of preventing the cover 2 from breaking and being damaged.

[0038] In a specific embodiment, such as Figure 1-4 As shown, the two ends of the gantry frame 11 are fixed to the two ends of the reinforcing beam 6 by bolts, which can not only make the gantry frame 11 more stably fixed on the cover 2, but also make the cylinder installed on the gantry frame 11 more stable and reliable.

[0039] In a specific embodiment, such as Figure 1 , 4 As shown, two lifting rings 14 are fixed to both ends of the reinforcing beam 6, and these two lifting rings 14 are integrally formed on both sides of the reinforcing beam 6. The lifting rings 14 facilitate the lifting of the cover seat 2 away from the furnace body 1 as a whole, thereby realizing the overall opening of the furnace body 1.

[0040] In a specific embodiment, such as Figure 3 , 4 As shown, hinge seats 15 are fixed on the reinforcing beam 6, and each heat insulation cover plate 10 is set on the cover 2 through the hinge seats 15.

[0041] In an optional embodiment, such as Figure 1 As shown, a protective cover 17 for covering the right feed notch 7 is also fixed to the cover 2 by bolts.

[0042] like Figure 5-6 As shown, this utility model also provides a lead melting furnace using the above-mentioned top cover device. The lead melting furnace includes a furnace body 1. Inside the furnace body 1, from left to right, there are a heat preservation zone 3, a stirring zone 4, and a melting zone 5. The stirring zone 4 and the melting zone 5 are connected at the bottom. The bottom of the stirring zone 4 is connected to the middle of the heat preservation zone 3 through a pipe. The four corners of the furnace body 1 have pin holes corresponding to the pin shaft 16. The cover seat 2 is fixed to the furnace body 1 by inserting the pin shaft 16 into the pin holes. The liquid level measuring component 8 and the stirring component 9 extend into the heat preservation zone 3 and the stirring zone 4 respectively through through holes.

[0043] It should be noted that the number of the above-mentioned functional areas matches the number of insulation cover plates 10. For example, when there are two or more mixing zones 4, the corresponding number of insulation cover plates 10 is also two or more.

[0044] In practical use, this utility model can transport lead ingots from the right feed notch 7 into the furnace body 1 using existing conventional conveying devices. The specific implementation principle is as follows:

[0045] After the lead ingots enter the melting zone 5, they melt into molten lead under the high temperature of conventional heating structures such as electric heating tubes. The molten lead then enters the stirring zone 4, where the stirring component 9 agitates the lead and causes impurities to float to the surface, facilitating slag removal. When the liquid level in the stirring zone 4 is higher than the pipe height, the molten lead enters the insulation zone 3 through the pipe. Due to the height difference between the insulation zone 3 and the stirring zone 4, the pipe acts as a filter for impurities. During the aforementioned melting process, the insulation cover 10 can be opened by a cylinder to allow real-time observation of the melting state and impurity status of the molten lead in each functional zone, thereby initiating the corresponding slag removal operation. When there is a sufficient amount of molten lead in the insulation zone 3, the outlet can be opened to discharge the molten lead.

[0046] In summary, this invention, due to its openable and closable cover 2 structure, allows for convenient and quick opening and closing of the insulation zone 3, stirring zone 4, and melting zone 5. This facilitates real-time observation of the lead melting process and real-time slag removal. It improves the quality of the molten lead and ensures the stability and reliability of lead ingot melting. Furthermore, the level measuring component 8 and the stirring component 9 are integrally integrated with the cover 2. In practical applications, simply fixing the cover 2 to the furnace body 1 achieves secure installation of the level measuring component 8 and the stirring component 9, making it more convenient and practical.

[0047] The above description is only a specific embodiment of the present utility model. Any feature disclosed in this specification may be replaced by other equivalent or similar features unless otherwise specified. All features or steps in all methods or processes disclosed may be combined in any way except for mutually exclusive features and / or steps.
