Description

Technical Field

[0001] This utility model relates to the technical field of desulfurization gun production equipment, and in particular to a desulfurization gun baking kiln. Background Technology

[0002] A desulfurization lance is a refractory component used for desulfurizing molten iron. During the production of desulfurization lances, the semi-finished product needs to be baked. However, due to the unique structure of the desulfurization lance, existing baking kilns are not suitable for direct baking; only specialized baking kilns can be used. Currently, desulfurization lance baking kilns generally use a vertical baking chamber, suspending the lance within it. Before baking, the lance is hoisted downwards into the chamber, and after baking, it is removed by hoisting upwards. During this hoisting process, the lance is prone to swaying, and the top of the baking chamber has a hanging component, resulting in a small opening at the top. This not only makes it difficult to align the lance with the chamber but also increases the risk of damage due to collisions. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a desulfurization gun baking kiln that facilitates the hoisting and transportation of desulfurization guns during the baking process.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a desulfurization gun baking kiln, including a kiln body, a baking chamber extending along the height direction of the kiln body, a heating wire in the baking chamber, the top and front end of the baking chamber are not closed, and the bottom and rear end of the baking chamber are closed; the top of the kiln body is provided with a first sealing door to close the top of the baking chamber, and the front end of the kiln body is provided with a second sealing door to close the front end of the baking chamber; the first sealing door is laid horizontally and can be moved horizontally, and the second sealing door is set vertically and can be moved horizontally; the top of the baking chamber is also provided with a desulfurization gun suspension bracket.

[0005] As a further improvement to the above scheme: the top of the kiln body is provided with a first horizontal slide rail, and the first sealing door is slidably engaged with the first horizontal slide rail; the front end of the kiln body is provided with a second horizontal slide rail, and the second sealing door is slidably engaged with the second horizontal slide rail; the projections of the first horizontal slide rail and the second horizontal slide rail on the horizontal plane are perpendicular to each other.

[0006] As a further improvement to the above scheme: the desulfurization gun suspension bracket consists of two supports that extend horizontally from both sides of the baking chamber into the baking chamber, with a gap between the two supports.

[0007] As a further improvement to the above solution: the top surface of the support is provided with a recessed limiting groove, which is a semi-circular groove, and the limiting grooves on the two supports are arranged opposite to each other.

[0008] As a further improvement to the above solution: the height of the desulfurization gun suspension bracket is lower than the top height of the baking chamber, and the desulfurization gun suspension bracket forms a stepped structure below the top of the baking chamber.

[0009] As a further improvement to the above scheme: the kiln body is composed of an outer cylinder, an insulation layer and a lining layer arranged sequentially from the outside to the inside.

[0010] As a further improvement to the above scheme: the outer cylinder of the kiln is a cylindrical structure made of steel plate, the insulation layer is formed by casting refractory material, and the lining layer is formed by building with insulating material.

[0011] As a further improvement to the above solution: the heating wire is attached to the inner walls of both sides of the baking cavity and extends along the height direction of the baking cavity.

[0012] The beneficial effects of this utility model are as follows: By improving the structure of the baking kiln for the desulfurization gun, this utility model adds an opening at the end to the existing baking chamber, which only has an opening at the top. By setting two sliding sealing doors to close the two openings of the baking chamber, the desulfurization gun can be directly hoisted horizontally into the baking chamber from the opening at the end of the baking chamber during the hoisting process. Then, the desulfurization gun is vertically hoisted into the baking chamber and suspended on the desulfurization gun suspension bracket. This effectively reduces the difficulty of hoisting the desulfurization gun during the baking process, and can effectively improve the baking efficiency and shorten the baking cycle.

[0014] The markings in the diagram are as follows: 100-kiln body, 110-outer cylinder of kiln, 120-insulation layer, 130-lining layer, 200-baking chamber, 210-desulfurization gun suspension bracket, 300-heating wire, 410-first sealing door, 420-first horizontal slide rail, 510-second sealing door, 520-second horizontal slide rail, 600-desulfurization gun, 610-flange, 620-gun core. Detailed Implementation

[0015] To facilitate understanding of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.

[0016] In the description of this utility model, it should be noted that the terms "front", "rear", "left", "right", "up", "down", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of description and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] like Figure 1 As shown, the main structure of the desulfurization gun baking kiln disclosed in this utility model is a kiln body 100. A vertical baking chamber 200 is provided inside the kiln body 100, extending along the height direction of the kiln body 100. A heating wire 300 for heating and baking the desulfurization gun 600 is provided inside the baking chamber 200. A desulfurization gun suspension bracket 210 is provided at the top of the baking chamber 200, used to suspend the desulfurization gun 600 to be baked, so that the desulfurization gun 600 remains in a vertical suspended state during the baking process. To facilitate the hoisting of the desulfurization gun 600, this utility model improves the structure of the baking chamber 200. The top and front end of the baking chamber 200 are not closed, while the bottom and rear end are closed; that is, openings communicating with the baking chamber 200 are provided at the top and front end. When hoisting the desulfurization gun 600 into the baking chamber 200, the desulfurization gun 600 can be directly hoisted horizontally from the front opening of the baking chamber 200 into the baking chamber 200. When the desulfurization gun 600 is hoisted close to the desulfurization gun suspension bracket 210, the desulfurization gun 600 is then hoisted upward and suspended on the desulfurization gun suspension bracket 210.

[0018] Compared with the prior art, the desulfurization gun baking kiln disclosed in this utility model eliminates the need to hoist the desulfurization gun 600 from the top opening of the baking chamber 200. This avoids aligning the desulfurization gun 600 with the upper opening of the baking chamber 200, which has a smaller opening size due to the suspension components. Instead, the desulfurization gun 600 is horizontally hoisted into the baking chamber 200 from the front opening at the front end. This provides a larger passage range for hoisting the desulfurization gun 600, effectively reducing the difficulty of hoisting operations for workers. It also provides more space to avoid swaying of the desulfurization gun 600 during hoisting, reducing the probability of collisions during hoisting.

[0019] To seal the two openings of the baking cavity 200, this invention employs two sealing doors. For example... Figure 1As shown, a first sealing door 410 is provided at the top of the kiln body 100 to close the top opening of the baking chamber 200, and a second sealing door 510 is provided at the front end of the kiln body 100 to close the front opening of the baking chamber 200. The first sealing door 410 is laid horizontally and can be moved horizontally, while the second sealing door 510 is set vertically and can be moved horizontally. The movement of the sealing doors is achieved by setting slide rails. A first horizontal slide rail 420 is provided at the top of the kiln body 100, and the first sealing door 410 slides in conjunction with the first horizontal slide rail 420. A second horizontal slide rail 520 is provided at the front end of the kiln body 100, and the second sealing door 510 slides in conjunction with the second horizontal slide rail 520. The projections of the first horizontal slide rail 420 and the second horizontal slide rail 520 on the horizontal plane are perpendicular to each other, that is, the movement directions of the first sealing door 410 and the second sealing door 510 are perpendicular to each other. The movement direction of the first sealing door 410 is the direction corresponding to the front and rear ends of the kiln body 100, and the movement direction of the second sealing door 510 is the direction corresponding to the left and right sides of the kiln body 100. The two sides of the first sealing door 410 can be bent downward to form bent edges to cover the first horizontal slide rail 420, and at the same time improve the sealing effect on the top opening of the baking cavity 200; the front end face of the kiln body 100 can be set as a plane to facilitate the translation of the second sealing door 510.

[0020] Specifically, such as Figure 1 As shown, the desulfurization gun suspension bracket 210 used in this utility model consists of two supports, both of which are flat structures made of thickened steel plates. The two supports extend horizontally from both sides of the baking chamber 200 toward the center of the baking chamber 200, with a gap between the two supports allowing the gun core 620 of the desulfurization gun 600 to pass through. The gap between the two supports is greater than the width of the gun core 620 of the desulfurization gun 600 and less than the width of the flange 610 of the desulfurization gun 600, so that the flange 610 of the desulfurization gun 600 can abut against the top of the support to form a vertical limiting fit, thereby suspending the desulfurization gun 600.

[0021] Furthermore, to improve the stability of the desulfurization gun 600 during the hoisting process, this invention optimizes the structure of the desulfurization gun suspension bracket 210. Recessed limiting grooves are provided on the top surface of both supports. These limiting grooves are semi-circular, and their shape matches the shape of the flange 610 of the desulfurization gun 600. The limiting grooves on the two supports are positioned opposite each other so that the flange 610 can be embedded in the limiting grooves when the desulfurization gun 600 is hoisted. The limiting effect of the limiting grooves on the flange 610 ensures that the desulfurization gun 600 will not shift or shake during hoisting. Since there is a gap between the two supports, the crane's lifting claws can grasp the flange 610 through the gap, thus not affecting the hoisting of the desulfurization gun 600. In addition, the present invention also limits the setting height of the desulfurization gun suspension bracket 210 to be lower than the top height of the baking chamber 200, and the desulfurization gun suspension bracket 210 forms a stepped structure below the top of the baking chamber 200 to prevent the top of the desulfurization gun 600 from extending outside the baking chamber 200.

[0022] Specifically, such as Figure 1 As shown, the kiln body 100 of this utility model consists of an outer cylinder 110, an insulation layer 120, and a lining layer 130; the outer cylinder 110, the insulation layer 120, and the lining layer 130 are arranged sequentially from the outside to the inside and are attached to each other in sequence. The outer cylinder 110 is a cylinder structure made of steel plate, the insulation layer 120 is formed by casting refractory material, and the lining layer 130 is formed by masonry of insulating material.

[0023] To ensure that the desulfurization gun 600 is heated evenly during the baking process, such as Figure 1 As shown, this invention provides heating wires 300 on both sides of the desulfurization gun 600, with the heating wires 300 abutting against the inner walls of the baking chamber 200 and extending along the height of the baking chamber 200. This arrangement of the heating wires 300 not only provides a stable and uniform heating effect for the desulfurization gun 600 but also does not obstruct the hoisting of the desulfurization gun 600.
