Description

Technical Field

[0001] The utility model relates to the technical field of smelting furnaces, in particular to a material pushing device for a smelting furnace. Background Art

[0002] When smelting metal in an electric arc furnace, a pushing device such as a tamping machine is required to adjust the material surface and furnace conditions so that the material distribution in the furnace is uniform, the reaction zone is expanded, and at the same time, floating materials are eliminated and the slag is crushed, thereby avoiding crusting and surface flame spraying, so that the electric furnace can maintain good operating conditions. At present, dedicated tamping machines have the following shortcomings when used: (1) Special equipment is expensive and has high maintenance costs; (2) The tamping machine mainly uses a fixed power supply to drive the tamping machine. Since the tamping machine has a large body and a tamping power cord, it is inconvenient to operate; (3) The tamping machine has a large force during the pushing process, which is easy to damage the furnace condition and seriously affect the production efficiency of the smelting furnace.

[0003] The patent with publication number CN207501710U discloses a furnace tamping machine that is easy to maintain, which includes a forklift, a heat insulation board, a connecting plate, a connecting arm, a furnace tamping arm and a furnace tamping plate; the connecting arm is in a rectangular tube shape, one end of which is welded to the connecting plate; one end of the furnace tamping arm is welded to the furnace tamping plate, and the other end is inserted into the connecting arm; the end surface of the connecting plate opposite to the furnace tamping plate is fixedly connected to the lifting frame by bolts, and a first reinforcing rib plate is provided at the connection between the connecting arm and the connecting plate, and a second reinforcing rib plate is provided at the connection between the furnace tamping arm and the furnace tamping plate. It effectively solves the shortcomings of the furnace tamping machine, which is expensive and inconvenient to operate, but it completely transforms the forklift into a furnace tamping device, which limits the use scenarios of the forklift.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Embodiment 1:

[0017] The present embodiment discloses a smelting furnace pushing device, which is modified from an existing forklift 1. The forks of the forklift 1 are removed and connected to a pushing arm 2, and the original hydraulic system and control system of the forklift 1 are used to realize the pushing operation.

[0018] Specifically, Figure 1 As shown, the pusher device includes a forklift 1, a pusher arm 2, and a clamping assembly 3. The forklift 1 includes a forklift body 1.1, a door frame 1.2, and a lifting frame 1.3 slidably connected to the door frame 1.2. One end of the pusher arm 2 is fixedly connected to the clamping assembly 3, and the clamping assembly 3 is detachably clamped on the lifting frame 1.3. Among them, the composition and control process of each component of the forklift 1 are mature existing technologies, which do not belong to the innovation of the utility model and will not be described in detail; the pusher arm 2 is a hollow tubular structure.

[0019] In this embodiment, the clamping assembly 3 is a U-shaped bracket 3.1, and its structure is as follows: Figure 2 As shown, a vertical end surface of the U-shaped bracket 3.1 is fixedly connected to one end of the pusher arm 2, and the open end of the U-shaped bracket 3.1 matches the lifting frame 1.3.

[0020] In order to effectively prevent the pusher arm 2 from melting, a cooling water tank 4 is fixedly provided inside the end of the pusher arm 2 away from the clamping assembly 3, and a water inlet 4.1 and a steam outlet 4.2 are respectively provided on the outer wall of the cooling water tank 4. Correspondingly, through holes matching the positions of the water inlet 4.1 and the steam outlet 4.2 are respectively provided on the outer wall of the pusher arm 2. Optionally, a detachable cover plate is provided at the water inlet 4.1, and the water inlet 4.1 is closed by the cover plate. Cooling water enters from the water inlet 4.1 provided on the outer wall of the cooling water tank 4, turns into steam after absorbing heat, and is discharged from the steam outlet 4.2; through the cooling effect of the cooling water tank 4, the pusher arm 2 is not easily melted and deformed by high temperature, which effectively extends the service life of the pusher arm 2. Among them, the cooling water can be replenished at intervals, that is, a large amount of cooling water is added into the cooling water tank 4 at one time, and the water inlet 4.1 is closed, and it is replenished again after the cooling water is consumed. It can also be replenished by an external water pump and water storage device according to the actual usage scenario. The water pump and water storage device can use commonly used existing technologies, which will not be described in detail here.

[0021] In order to improve the pushing efficiency of the pushing device, a pushing plate 2.1 is fixedly connected to the end of the pushing arm 2 away from the clamping assembly 3. The pushing plate 2.1 effectively increases the contact area between the device and the material surface. Since the pushing plate 2.1 is small in size relative to the pushing arm 2, it is easy to replace. When the pushing plate 2.1 is damaged, it can be replaced in time. In order to improve the connection stability of the device, a first reinforcing rib 5 is fixedly connected to the connection between the clamping assembly 3 and the pushing arm 2, and a second reinforcing rib 6 is fixedly connected to the connection between the pushing plate 2.1 and the pushing arm 2.

[0022] Instructions for use: When using the pushing device of this embodiment, first fix the pushing arm 2 and the clamping assembly 3 (wherein the fixed connection method adopts a commonly used connection method, such as welding, etc.), and remove the fork of the forklift 1; then, the clamping assembly 3 is mounted on the lifting frame 1.3 of the forklift 1, and the pushing device can be put into use. The staff can adjust the furnace surface of a specific part of the ore-fired furnace by controlling the hydraulic system and engine system of the forklift 1.

[0023] During the pushing process, the cooling water tank 4 provided in the pushing arm 2 can absorb part of the heat to prevent the pushing arm 2 from melting. After the pushing is completed, the clamping assembly 3 is removed from the lifting frame 1.3, and the forklift 1 can be put into other production.

[0024] In addition, the pusher arm 2 and the pusher plate 2.1 in this embodiment can be replaced. For example, they can be replaced with a charging device, and can be used for charging a submerged arc furnace.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
