Description

Technical Field

[0001] This utility model belongs to the technical field of smelting furnaces and their accessories, and in particular relates to a movable furnace cover for a metal smelting furnace. Background Technology

[0002] The smelting furnace is one of the most important pieces of equipment in the metal smelting process. The smelting furnace mainly consists of two parts: the furnace body and the furnace cover. The furnace cover is rotatably connected to the top of the furnace body, which serves to cover the top of the furnace body. At the same time, the opening and closing of the furnace cover also requires mechanical equipment, which provides power support for the closing of the furnace cover through mechanical pushing.

[0003] Chinese patent application CN211527097U discloses a movable furnace cover for a metal smelting furnace, comprising a smelting furnace, a furnace cover on the top of the smelting furnace, a toothed ring welded to the surface of the furnace cover, limit frames fixedly connected to the top of the left and right sides of the smelting furnace surface, a pressure plate fixedly connected to the top of the limit frame, a pressing component provided on the inner side of the top of the pressure plate, and a transmission mechanism fixedly connected to the left side of the limit frame. This invention, through the arrangement of the smelting furnace, furnace cover, toothed ring, limit frame, pressure plate, pressing component, transmission mechanism, and cleaning block, solves the problems of existing smelting furnace covers easily adsorbing smelting residue, and the difficulty in cleaning the residue accumulation areas, resulting in the inability to reuse the waste residue on the furnace cover and affecting the recovery of waste gas and the reuse of waste residue. This movable furnace cover for a metal smelting furnace has the advantage of facilitating the cleaning of furnace cover residue, thus improving the cleaning effect of the furnace cover.

[0004] The aforementioned movable furnace cover for a metal smelting furnace has a transmission mechanism on its side, mainly composed of a motor and two gears. During operation, the furnace body and furnace cover reach extremely high temperatures, and the motor's location beside the cover exacerbates the problem, as the high-temperature environment significantly impacts its performance. Furthermore, a limit frame is installed on the side of the furnace body's top, with a clamping component at its top. The furnace cover directly closes to the furnace body, with the clamping component on the limit frame pressing the cover against the upper part of the furnace body. The clamping component consists of a screw, pressure blocks fixed at both ends, and a knob. Opening the furnace cover requires rotating the screw to disengage the bottom pressure blocks, an operation that is extremely difficult to perform due to the temperature of the furnace body and cover, as well as the furnace's height, making the furnace cover very difficult to open. Therefore, we provide a movable furnace cover for a metal smelting furnace to solve the aforementioned problems. Utility Model Content

[0015] The present invention is further configured such that an installation hole is provided on the mating groove in the upper side wall of the furnace cover body, the elastic element includes a column sleeve fixed in the installation hole, a spring is placed in the column sleeve, and a sliding column is slidably inserted into the upper end of the column sleeve, the top end of the sliding column is fixed on the bottom side wall of the large-diameter circular plate at the upper end of the sealing column.

[0016] This utility model has the following beneficial effects:

[0017] This utility model features a furnace top plate and a furnace cover body. The furnace top plate is fixedly installed on the top of the furnace body, and the furnace cover body is slidably inserted into the side of the furnace top plate. The furnace cover body can slide on the furnace top plate with the power support of a traction machine. The furnace cover body serves to cover the furnace cover opening on the furnace top plate. When the furnace cover body slides on the furnace top plate, the bottom of the furnace cover body also rubs against the furnace top plate, thereby scraping the slag on the bottom of the furnace cover body and causing it to fall back into the furnace body through the furnace cover opening, thus cleaning the slag on the furnace cover body.

[0018] This invention comprises a furnace top plate, a furnace cover body, a sealing column, and an elastic element. The furnace cover body is horizontally slidably inserted into the furnace top plate. Both sides of the furnace cover body are detachably equipped with traction rods for connection to traction machinery hooks, which are also slidably inserted into the furnace top plate. A sealing column with an I-shaped cross-section is slidably positioned at the center of the furnace cover body, allowing it to slide up and down within the furnace cover body. An elastic element is also provided between the upper plate of the sealing column and the furnace cover body, providing a downward pulling force to the sealing column. This ensures that when the furnace cover body covers the furnace opening at the top of the furnace, the sealing column passes directly through the furnace top. The plate is inserted into the furnace opening at the top of the furnace body to seal the furnace opening. When opening, the sealing column is pulled up by the traction mechanism, and the bottom plate of the sealing column is pulled back to the furnace cover body, so that the bottom of the sealing column is flush with the bottom of the furnace cover body. Then, the hook of another traction mechanism clamps the column or gets into the pull ring at the end of the traction rod and pulls it outward. At this time, the traction rod can pull the furnace cover body to slide outward on the furnace top plate, thus realizing the opening effect of the furnace opening at the top of the furnace body. Conversely, it closes. The traction mechanism applies force in both vertical and horizontal directions, without the need for cumbersome actions such as rotation and position adjustment.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0028] Please see Figure 1-4 This utility model is a movable furnace cover for a metal smelting furnace, including a furnace body 1, a furnace top plate 3 and a furnace cover body 4. By sliding the furnace cover body 4, which is inserted into the side of the furnace top plate 3, the furnace opening at the top of the furnace body 1 can be opened or closed in a horizontal direction. The furnace cover body 4 also achieves the effect of cleaning slag during the opening process.

[0029] Specifically, the bottom of the furnace body 1 is fixed inside the furnace base 2, and the top of the furnace body 1 is provided with a connecting groove 101 for installing the connecting ring 301. The connecting ring 301 is welded to the bottom side wall of the furnace top plate 3, and the inner side of the connecting ring 301 on the furnace top plate 3 is provided with a furnace cover opening 302a. The side wall of the furnace top plate 3 is also provided with a plate sliding groove 302. The furnace top plate 3 is slidably connected to the furnace cover body 4 through the plate sliding groove 302.

[0030] Furthermore, sliders 403 are welded to both sides of the furnace cover body 4, and block grooves 303 are also provided on the inner walls of both sides of the plate groove 302. The block grooves 303 slide in cooperation with the sliders 403, and shaft holes 303a are provided at the ends of the block grooves 303. Positioning grooves 403a are provided on the sliders 403 for the positioning blocks 404a to engage. The positioning blocks 404a are welded to both ends of the traction rod 404, and the traction rod 404 is also slidably connected to the shaft holes 303a. Pull rings 404b are also fixedly installed on the positioning blocks 404a located on the outer shaft end of the traction rod 404.

[0031] The operation process of this embodiment is as follows: When in use, the hook of the traction machine on the metal smelting production line is used to hold or hang on the pull ring 404b. Then the traction machine applies force, and the pull ring 404b applies traction force to the traction rod 404, which can drag the furnace cover body 4 to slide in the plate slide groove 302 of the furnace top plate 3, thereby achieving the effect of opening or closing the furnace cover opening 302a. Furthermore, due to the setting of the slider 403, the furnace cover body 4 can be prevented from slipping off the furnace top plate 3. Example 2

[0032] Please see Figure 4-5 Based on embodiment 1, a sealing column 5 and an elastic element 6 are also provided. The elastic element 6 provides a downward pulling force to the sealing column 7, ensuring that when the furnace cover body 4 covers the furnace opening at the top of the furnace body 1, the sealing column 5 is directly inserted into the furnace opening at the top of the furnace body 1, thereby improving the sealing effect of the furnace opening of the furnace body 1.

[0033] Specifically, the furnace cover body 4 has a furnace cover opening 401. The upper and lower sides of the furnace cover opening 401 are provided with mating grooves 402 on the outer wall of the furnace cover body 4. The upper mating groove 402 is also provided with an installation hole 402a. The sealing column 5 has an I-shaped cross section. The inner wall of the furnace cover opening 401 is in sliding fit with the outer side of the small diameter cylinder of the sealing column 5. The mating grooves 402 on the upper and lower sides of the furnace cover opening 401 are in fit with the outer wall of the large diameter circular plate of the sealing column 5. The installation hole 402a is connected to the large diameter circular plate at the upper end of the sealing column 5 through the elastic element 6.

[0034] Furthermore, the elastic element 6 includes a mounting ring 601a fixed in the mounting hole 402a, and the furnace cover body 4 is fixedly connected to the column sleeve 601 through the mounting ring 601a. ​​A spring 602 is placed inside the column sleeve 601, and a sliding column 603 is slidably inserted into the upper end of the column sleeve 601. The top end of the sliding column 603 is fixed on the bottom side wall of the large-diameter circular plate at the upper end of the sealing column 5.

[0035] The operation process of this embodiment is as follows: During use, the spring 602 in the elastic element 6 provides a downward pulling force to the sealing column 5, ensuring that when the furnace cover body 4 covers the furnace opening at the top of the furnace body 1, the sealing column 5 directly passes through the furnace top plate 3 and inserts into the furnace opening at the top of the furnace body 1, thereby achieving the effect of sealing the furnace opening of the furnace body 1. When opening, the sealing column 5 is lifted by the traction mechanism, and the bottom circular plate of the sealing column 5 is pulled back to the furnace cover body 4, so that the bottom of the sealing column is flush with the bottom of the furnace cover body. Then, under the cooperation of the traction mechanism in embodiment 1, the furnace cover body 4 is pulled outward from the horizontal direction. At this time, the bottom of the furnace cover body 4 and the bottom of the sealing column 5 are in contact with the bottom side wall of the upper sliding groove 302 of the furnace top plate 3, and a scraping phenomenon is formed, thereby achieving the effect of scraping the slag on the bottom of the furnace cover body 4 and the sealing column 5, so that it falls back into the furnace body 1 through the furnace cover opening.
