Description

Technical Field

[0001] This utility model relates to the field of heat treatment furnace technology, and in particular to a heat treatment furnace for titanium anode production. Background Technology

[0002] A titanium anode is an anode material made of pure titanium. Pure titanium has excellent corrosion resistance and biocompatibility, and therefore is widely used in many fields. Titanium anodes are commonly used in electrochemistry, such as as anodes in electrolytic cells to participate in electrochemical reactions. In addition, due to its good corrosion resistance and conductivity, titanium anodes can also be used in battery manufacturing, aluminum electrolysis, electroplating, and other processes.

[0003] As an important piece of equipment in electrolytic reactions, titanium anode plates require heat treatment to form a metal particle coating on their surface before use. Existing heat treatment processes for titanium anode plates require high-temperature heating, but traditional heat treatment furnaces mainly heat the upper surface of the titanium anode plate, resulting in uneven heating. This can easily lead to a decline in the quality of the surface coating and also cause excessively long heating times. Utility Model Content

[0004] The purpose of this invention is to provide a heat treatment furnace for titanium anode production, which solves the problem that traditional heat treatment furnaces mainly heat the upper surface of titanium anode plates, resulting in uneven heating, which easily leads to a decline in the surface coating quality of titanium anode plates, and also causes excessively long heating times.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model discloses a heat treatment furnace for titanium anode production, comprising a protective shell, a furnace body disposed inside the protective shell, a furnace door disposed at the front of the furnace body, an air inlet pipe disposed on the right side wall of the furnace body, and an exhaust pipe disposed on the top surface of the furnace body. Both the air inlet pipe and the exhaust pipe extend to the outside of the protective shell. A cavity is disposed inside the protective shell and below the furnace body. A first support frame is disposed at the bottom of the cavity. A second support frame and a third support frame are disposed on the right side of the protective shell. A track is disposed at the front of the protective shell, and a transfer trolley is disposed on the track. The furnace body also includes a lifting trolley. A placement rack for placing titanium anode plates is disposed on the top surface of the lifting trolley. The lifting trolley can move onto the first support frame, the second support frame, the third support frame, or the transfer trolley. Heating pipes are disposed on the inner walls of the furnace body and the furnace door, as well as on the lifting trolley.

[0007] Furthermore, the lifting vehicle includes a base frame and a top frame. The base frame is equipped with casters around its perimeter. Multiple sets of folding components are arranged between the base frame and the top frame. A drive mechanism for unfolding the folding components is arranged between the multiple sets of folding components. A heat insulation plate, a heating and heat preservation cavity, and a heat conduction plate are arranged sequentially on the top surface of the top frame. The placement rack is arranged on the top surface of the heat conduction plate. The heating pipe is arranged inside the heating and heat preservation cavity.

[0008] Furthermore, the number of folding components is set to four groups, and the four groups of folding components are distributed in a rectangular pattern.

[0009] Furthermore, the driving mechanism includes an operating lever with two threaded segments with opposite directions of rotation. A connecting rod is provided between the two sets of folding components that are corresponding to each other. A moving block is provided in the middle of the two connecting rods, and the two moving blocks are threadedly connected to the two threaded segments respectively.

[0010] Furthermore, the folding assembly includes a first folding rod and a second folding rod. The top end of the first folding rod is hinged to the top frame, and the bottom end of the second folding rod is hinged to the base frame. The bottom end of the first folding rod and the top end of the second folding rod are movably connected to the connecting rod.

[0011] Furthermore, the exposed end of the operating lever is provided with a crank handle.

[0012] Furthermore, both the intake pipe and the exhaust pipe are equipped with control valves.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] This utility model has several heating tubes installed on the left, right and rear sides of the furnace body, and heating tubes are also installed on the inner wall of the furnace door and the top of the lifting vehicle. It can heat the titanium anode plate from all sides at the same time, so that the heating is uniform, the heating time is shortened, and the surface coating quality of the titanium anode plate is improved. The work efficiency is improved by having two lifting vehicles alternately enter the furnace body for heat treatment. The transfer efficiency of the lifting vehicle is improved by setting up a transfer vehicle. Attached Figure Description

Detailed Implementation

[0023] like Figure 1-5 As shown, a heat treatment furnace for titanium anode production includes a protective shell 1, a furnace body 2 installed inside the protective shell 1, a furnace door 3 hinged to the front of the furnace body 2, a locking mechanism installed on the right side of the furnace body 2 and the furnace door 3, multiple air inlet pipes 5 connected to the right side wall of the furnace body 2, and multiple exhaust pipes 6 connected to the top surface of the furnace body 2. Both the air inlet pipes 5 and the exhaust pipes 6 extend to the outside of the protective shell 1, and control valves are installed on both the air inlet pipes 5 and the exhaust pipes 6. The air inlet pipes 5 are connected to an inert gas delivery pipeline. A cavity is formed inside the protective shell 1 below the furnace body 2, and the bottom of the cavity... The protective shell 1 is equipped with a first support frame 7, a second support frame 9 and a third support frame 10 on the right side, a track 8 in front of the protective shell 1, a transfer cart 13 on the track 8 with wheels matching the track 8, and a lifting cart 11. The top surface of the lifting cart 11 is connected to two sets of placement racks 12 for placing titanium anode plates 14. The lifting cart 11 can move onto the first support frame 7, the second support frame 9, the third support frame 10 or the transfer cart 13. Several heating tubes 4 are installed on the inner walls of the furnace body 2 and the furnace door 3, as well as on the lifting cart 11.

[0024] Specifically, the locking mechanism includes a screw connected to the furnace body 2. A slot is provided on the right side of the furnace door 3. The screw is inserted into the slot, and the locking disc threaded on the screw is tightened so that the locking disc presses against the furnace door 3, thereby locking the position of the furnace door 3.

[0025] like Figure 3-4 As shown, the lifting vehicle 11 includes a base frame 11-1 and a top frame 11-3. Four casters 11-2 are installed around the base frame 11-1, allowing movement along tracks on the top of the first support frame 7, the second support frame 9, the third support frame 10, or the transfer vehicle 13. Four sets of folding assemblies 11-4 are installed between the base frame 11-1 and the top frame 11-3, arranged in a rectangular pattern. A mechanism for driving the lifting vehicle 11 is provided between the four sets of folding assemblies 11-4. The folding assembly 11-4 is driven by a mechanism. The top surface of the top frame 11-3 is sequentially equipped with a heat insulation plate 11-9, a heating and heat preservation cavity 11-10, and a heat conduction plate 11-11. The top surface of the heat conduction plate 11-11 is connected to the placement rack 12. Several heating tubes 4 are installed inside the heating and heat preservation cavity 11-10. The bottom frame 11-1 is also equipped with a power supply for the heating tubes 4. Both the power supply and the heating tubes are existing technologies, and their specific structures and wiring connections are conventional techniques, which will not be described in detail here.

[0026] The driving mechanism includes an operating lever 11-6, on which two threaded segments 11-6-1 with opposite directions of rotation are connected. A connecting rod 11-5 connects the two sets of folding components 11-4 corresponding to each other. A moving block 11-7 is connected to the middle of the two connecting rods 11-5. A threaded hole matching the threaded segment 11-6-1 is opened in the middle of the moving block 11-7. The two threaded segments 11-6-1 are respectively threaded into the threaded holes on the two moving blocks 11-7. A crank handle 11-8 is installed on the exposed end of the operating lever 11-6.

[0027] The folding assembly 11-4 includes a first folding rod 11-4-1 and a second folding rod 11-4-2. The top end of the first folding rod 11-4-1 is hinged to the top frame 11-3, and the bottom end of the second folding rod 11-4-2 is hinged to the base frame 11-1. The bottom end of the first folding rod 11-4-1 and the top end of the second folding rod 11-4-2 are movably connected to the connecting rod 11-5.

[0028] In use, rotating the operating lever 11-6 causes the two threaded sections 11-6-1 with opposite directions of rotation to rotate, making the two moving blocks 11-7 move closer or further apart. Rotating the operating lever 11-6 in the forward direction brings the two moving blocks 11-7 closer together, folds the first folding rod 11-4-1 and the second folding rod 11-4-2, causing the top frame 11-3 to descend and the height of the lifting vehicle 11 to decrease. Rotating the operating lever 11-6 in the reverse direction moves the two moving blocks 11-7 further apart, unfolds the first folding rod 11-4-1 and the second folding rod 11-4-2, and causes the top frame 11-3 to rise. When both the first folding rod 11-4-1 and the second folding rod 11-4-2 are vertical, stop rotating the operating lever 11-6, and the top frame 11-3 rises to its highest point, reaching the maximum height of the lifting vehicle 11.

[0029] like Figure 5 As shown, the placement rack 12 includes a bottom frame with multiple vertical supports connected to it. The titanium anode plate 14 is placed between two adjacent vertical supports, which separate the titanium anode plate 14.

[0030] The working process of this utility model is as follows:

[0031] First, place multiple titanium anode plates 14 on the placement rack 12. Then, push the lifting cart 11 to move it onto the transfer cart 13. Next, push the transfer cart 13, which will move the lifting cart 11 along the track 8 to the front of the furnace body 2. Then, push the lifting cart 11 onto the first support frame 7 and adjust the height of the lifting cart 11 so that the top frame 11-3 is close to the bottom surface of the furnace body 2. The heat insulation plate 11-9, the heating and heat preservation cavity 11-10, and the heat conduction plate 11-11 are located at the opening at the bottom of the furnace body 2. Seal the opening at the bottom of the furnace body 2 and close and lock the furnace door 3.

[0032] The control valve on the inlet pipe 5 is opened, and the inert gas is sent into the furnace body 2 through the external active gas supply system. Because the density of the inert gas is relatively low and its chemical properties are more stable compared with other components in the air (such as nitrogen and oxygen), it will form a stratification in the air. The lower layer of inert gas pushes the top air out of the top exhaust pipe 6. A concentration detector is installed on the exhaust pipe 6, which monitors the inert gas content in the exhaust gas in real time. When the value reaches the design requirements, the control valve on the exhaust pipe 6 is closed first, and then the control valve on the inlet pipe 5 is closed. During the process, the internal air pressure of the furnace body 2 is increased. The pressure sensor monitors in real time to prevent air leakage in the furnace body 2, which would allow air to mix into the furnace body 2 and destroy the inert gas protective atmosphere, thus maintaining the purity of the internal atmosphere. The temperature is increased by the heating pipe 4, and the titanium anode plate 14 is heat-treated under the protection of the inert gas atmosphere.

[0033] After heat treatment, open furnace door 3, adjust the lifting cart 11 to lower its height, then move the lifting cart 11 to transfer cart 13, push transfer cart 13, and transfer cart 13 will move the lifting cart 11 along track 8 to the front of the second support frame 9. Push the lifting cart 11 onto the second support frame 9 for temporary storage. After that, transfer cart 13 will go to the third support frame 10 to transport another lifting cart 11 with titanium anode plate 14 installed, so that the other lifting cart 11 can enter the furnace body 2 for heat treatment. By using two lifting carts 11, the working efficiency is improved.
