Description

Technical Field

[0001] This utility model relates to the field of anchor chain processing technology, specifically to an anchor chain heat treatment device. Background Technology

[0002] Anchor chains are chains that connect the anchor to the hull, used to transmit and cushion external forces acting on the ship. Currently, to ensure anchor chains can withstand greater strength, heat treatment is required during manufacturing, typically using a furnace. However, due to the length and weight of the anchor chain, coupled with limited space within the furnace, loading and unloading becomes inconvenient, causing the chain to accumulate and affecting processing efficiency. Furthermore, residual rust-preventive oil on the anchor chain surface emits an unpleasant odor during heat treatment, and oxide scale forms on the surface, negatively impacting the on-site processing environment. Utility Model Content

[0003] To address the aforementioned shortcomings, this invention provides an anchor chain heat treatment device that facilitates the handling and placement of anchor chains, improves work efficiency, and avoids environmental pollution during the heat treatment process.

[0004] To achieve the above objectives, the present invention provides a technical solution for an anchor chain heat treatment device, comprising a furnace body and a base plate. One side and bottom of the furnace body are open. The furnace body is positioned on top of the base plate. A base is fixedly connected to the top of the base plate. A sealing plate is provided on one side of the top of the base plate. Rollers are provided on both sides of the bottom of the furnace body. The two sides of the base are slidably connected to the inner wall of the furnace body. When one side of the furnace body is in contact with the surface of the sealing plate, the interior of the furnace body is a sealed space. A support rod is vertically fixedly connected to the top of the base. A hanging rod is fixedly connected to the top of the support rod. Evenly distributed heating wires are provided on the inner wall of the furnace body. An exhaust pipe is connected to the top of the furnace body. A butterfly valve is also provided on the surface of the exhaust pipe. A filter screen is provided inside the exhaust pipe near the outlet. A protective cover is provided at one end of the exhaust pipe.

[0005] Preferably, multiple hangers are provided and arranged in a ring on the top of the support rod, and a fixing pin is vertically fixed to the top of each hanger.

[0006] Preferably, the base has sealing grooves on both sides, the inner wall of the furnace body has protrusions that match the sealing grooves, and the surface of the sealing plate has a sealing frame that matches the furnace body.

[0007] Preferably, the exhaust pipe is also equipped with an exhaust fan, and the filter screen is an activated carbon filter screen or a dust filter screen.

[0008] Preferably, the surface of the furnace body is provided with a control panel electrically connected to the heating wire.

[0009] Preferably, the furnace body is fixedly connected to both sides with fixing buckles, and the surface of the sealing plate is provided with fixing seats that are compatible with the fixing buckles.

[0010] Preferably, the fixing buckle includes a connecting seat, a rotating rod is rotatably connected inside the connecting seat, a handle is fixedly connected to one end of the rotating rod, and a locking block is fixedly connected to the other end of the rotating rod.

[0011] The present invention adopts the above-mentioned technical solution, and its beneficial effects include: This anchor chain heat treatment equipment, by changing the traditional furnace structure and designing the bottom of the furnace body separately from the furnace body, is not affected by the internal space of the furnace when loading and unloading anchor chains, thus improving the efficiency of loading and unloading; at the same time, by fixing the hanging rod with the support rod, the anchor chain can be directly suspended in the furnace, avoiding the anchor chain from piling up and ensuring that the anchor chain is arranged in an orderly manner during heat treatment; in addition, a filter screen is also installed in the exhaust pipe, which reduces the emission of odor and oxide scale powder into the air during exhaust, reduces pollution to the on-site environment, and is beneficial to the health of on-site workers.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: an anchor chain heat treatment device, including a furnace body 1 and a bottom plate 4. The surface and bottom of one side of the furnace body 1 are open. The furnace body 1 is set on the top of the bottom plate 4. A base 3 is fixedly connected to the top of the bottom plate 4. A sealing plate 2 is provided on one side of the top of the bottom plate 4. Both the base 3 and the sealing plate 2 are provided with heat insulation layers to prevent the bottom of the base 3 and the surface of the sealing plate 2 from generating high temperatures when the furnace body 1 is working.

[0019] Rollers 8 are provided on both sides of the bottom of the furnace body 1. The two sides of the base 3 are slidably connected to the inner wall of the furnace body 1. Sealing grooves 14 are provided on both sides of the base 3. The inner wall of the furnace body 1 is provided with protrusions that are adapted to the sealing grooves 14. The sealing grooves 14 and the protrusions help to improve the sealing between the base 3 and the furnace body 1. When one side of the furnace body 1 is in contact with the surface of the sealing plate 2, the inside of the furnace body 1 is a sealed space. In order to further improve the sealing of the furnace body 1, a sealing frame 15 adapted to the furnace body 1 is provided on the surface of the sealing plate 2. The outer contour of the sealing frame 15 is in contact with the inner wall of the furnace body 1.

[0020] A support rod 5 is vertically fixed to the top of the base 3. Multiple support rods 5 can be installed depending on the internal space of the furnace body 1. A hanging rod 6 is fixedly connected to the top of the support rod 5. Multiple hanging rods 6 are arranged in a ring on the top of the support rod 5. Multiple hanging rods 6 improve space utilization and ensure that more anchor chains can be heated at one time. To prevent the anchor chain from slipping off the surface of the hanging rod 6, a fixing pin 13 is vertically fixed to the top of the hanging rod 6. When hanging the anchor chain, the ring of the anchor chain is placed on the fixing pin 13.

[0021] The inner wall of the furnace body 1 is provided with evenly distributed heating wires 7, and the surface of the furnace body 1 is provided with a control panel 17 electrically connected to the heating wires 7. Heating is achieved by energizing the heating wires 7.

[0022] The top of the furnace body 1 is connected to an exhaust pipe 9, and a butterfly valve 10 is installed on the surface of the exhaust pipe 9. A filter screen 11 is installed inside the exhaust pipe 9 near the outlet. A protective cover screen 12 is installed at one end of the exhaust pipe 9. The butterfly valve 10 is closed when the heating wire 7 is working to reduce heat loss from the exhaust pipe 9. An exhaust fan 16 is also installed inside the exhaust pipe 9. The filter screen 11 is an activated carbon filter or a dust filter. The exhaust fan 16 improves the exhaust efficiency. The dust filter can isolate oxide powder, and the activated carbon filter can reduce the emission of odor into the air, thereby reducing air pollution.

[0023] The furnace body 1 is fixedly connected to both sides by fixing buckles 18, and the surface of the sealing plate 2 is provided with fixing seats 19 that are compatible with the fixing buckles 18. The fixing buckles 18 and fixing seats 19 can ensure that the furnace body 1 and the sealing plate 2 are in close contact when the furnace body 1 is heated.

[0024] like Figure 4As shown, the fixing buckle 18 includes a connecting seat 181, a rotating rod 182 rotatably connected inside the connecting seat 181, a handle 183 fixedly connected to one end of the rotating rod 182, and a locking block 184 fixedly connected to the other end of the rotating rod 182. The fixing seat 19 has a circular space inside, and the surface of the fixing seat 19 has a through hole that matches the locking block 184. In use, the furnace body 1 is moved to the side of the sealing plate 2 so that the locking block 184 is inserted into the fixing seat 19, and the rotating rod 182 is rotated by the handle 183 to achieve the locking of the fixing buckle 18 and the fixing seat 19.
