Description

Technical Field

[0001] This utility model relates to the field of sponge titanium production technology, and in particular to an automatic venting device for a sponge titanium reactor. Background Technology

[0002] The production of sponge titanium mainly adopts the method of magnesium reduction of titanium tetrachloride. During this reaction, magnesium chloride vapor and other by-product gases are generated. The timely removal of these gases is crucial to ensuring the normal progress of the reaction and the quality of the product.

[0003] However, the emission of exhaust gas faces many challenges in actual use. Since the sponge titanium reactor needs to be frequently transferred between different processes, it is extremely inconvenient to install complex venting devices.

[0004] Therefore, traditional manual venting is still widely used. Operators need to perform venting operations frequently, which is labor-intensive and inefficient. More importantly, manual venting makes it difficult to accurately control the venting time, which often leads to untimely or excessive venting, thus negatively impacting the stability of the production process and reducing overall production efficiency.

[0005] Therefore, developing an automatic venting device suitable for sponge titanium reactors is of great practical significance. Utility Model Content

[0006] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose an automatic venting device for a sponge titanium reactor to solve the problems mentioned in the background art.

[0007] To achieve the above technical objectives, the present invention provides an automatic venting device for a titanium sponge reactor, comprising an exhaust pipe, an exhaust valve, and a pressure transmission mechanism disposed on the top cover of the reactor. The lower ends of the exhaust valve and the pressure transmission mechanism are connected to the interior of the top cover of the reactor. The top of the exhaust valve is connected to the exhaust pipe. The pressure transmission mechanism drives the exhaust valve to open or close. The pressure transmission mechanism includes a pressure-resistant pipe, in which a bellows and a piston rod are disposed. One end of the bellows is closed, and the other end is fixedly connected to the lower end of the pressure-resistant pipe. One end of the piston rod is kept free to slide within the pressure-resistant pipe, and the other end is connected to the control end of the exhaust valve via a connecting rod. Hydraulic oil is disposed in the pressure-resistant pipe between the bellows and the piston rod.

[0008] Furthermore, the exhaust valve includes a valve tube, a valve core is disposed inside the valve tube, the valve core is connected to the valve tube via fins, a valve stem is disposed on the valve core, a valve plate is disposed at the lower end of the valve stem, and the upper end passes through the valve core and is kept to slide freely on it, a rocker arm is disposed at the upper part of the valve tube, the middle part of the rocker arm is rotatably connected to the valve tube, one end of the rocker arm inside the valve tube is pressed against the upper end of the valve stem, and a return spring is disposed on the valve stem between the rocker arm and the valve core, the upper and lower ends of the return spring being connected to the valve stem and the valve core respectively.

[0009] Furthermore, the reactor top cover has a circumferential array of several exhaust valves and pressure transmission mechanisms, and the exhaust pipe is provided with several branch pipes, which connect the exhaust valves to the exhaust pipe.

[0010] Furthermore, the piston rod is provided with a U-shaped seat at the top, and a strip-shaped sliding hole is provided on the side of the U-shaped seat. A sliding column adapted to the strip-shaped sliding hole is provided in the middle of the connecting rod. One end of the connecting rod is fixedly connected to the swing arm, and a counterweight is provided at the other end.

[0011] Furthermore, the connecting rod is provided with several slots along its length, and the counterweight and the connecting rod are engaged through the slots.

[0012] Compared with the prior art, the beneficial effects of this utility model include:

[0013] 1. This utility model automatically senses pressure changes inside the reactor and drives the exhaust valve to open or close via a pressure transmission mechanism, eliminating the need for frequent manual operation, greatly reducing labor intensity, and enabling precise control of gas release. The circumferential array of exhaust valves and pressure transmission mechanism, combined with the multi-branch design, is not only suitable for situations where the reactor is frequently transferred, but also improves exhaust efficiency. The redundant design of the multi-branch design further enhances the safety of equipment operation, extends the maintenance cycle, and ensures the stable and efficient operation of the production process.

[0014] 2. This utility model, through the design of a lockable counterweight on the connecting rod, allows for adjustment of the torque balance of the connecting rod by changing the position of the counterweight on the connecting rod, thereby achieving flexible adjustment of the exhaust pressure and realizing the purpose of graded control of pressure thresholds. This enables the gas in the reactor to be released quickly and accurately according to different pressure conditions, better adapting to the pressure change requirements in the production process of sponge titanium, effectively improving product quality and production flexibility, and providing a strong guarantee for the stable production of sponge titanium.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Reference Figure 1 This invention provides an automatic venting device for a titanium sponge reactor, including an exhaust pipe 2, an exhaust valve 4, and a pressure transmission mechanism 5 mounted on the reactor top cover 1. The lower ends of both the exhaust valve 4 and the pressure transmission mechanism 5 are connected to the interior of the reactor top cover 1. Several exhaust valves 4 and pressure transmission mechanisms 5 are arranged in a circumferential array on the reactor top cover 1. Several branch pipes 3 are provided on the exhaust pipe 2, connecting the exhaust valve 4 to the exhaust pipe 2. The pressure transmission mechanism 5 is connected to the exhaust valve 4 via a connecting rod 6, thereby opening or closing it.

[0020] Reference Figure 2 The pressure transmission mechanism 5 includes a pressure-resistant pipe 501, a bellows 502 and a piston rod 503 inside the pressure-resistant pipe 501. One end of the bellows 502 is closed, and the other end is fixedly connected to the lower end of the pressure-resistant pipe 501. One end of the piston rod 503 is kept free to slide inside the pressure-resistant pipe 501, and the other end is provided with a U-shaped seat 505. A strip-shaped sliding hole 504 is provided on the side of the U-shaped seat 505. Hydraulic oil is provided inside the pressure-resistant pipe 501 between the bellows 502 and the piston rod 503. When the pressure inside the reactor changes, the bellows 502 will deform, pushing the piston rod 503 to slide inside the pressure-resistant pipe 501, thereby driving the exhaust valve 4 to operate through the connecting rod 6.

[0021] The middle part of the connecting rod 6 is provided with a sliding column that matches the strip-shaped sliding hole 504. One end of the connecting rod 6 is connected to the operating part of the exhaust valve 4, and the other end is provided with a counterweight 7. The connecting rod 6 is provided with several slots along its length, and the counterweight 7 and the connecting rod 6 are engaged through the slots.

[0022] Reference Figure 3The exhaust valve 4 includes a valve pipe 401, a valve core 402 disposed inside the valve pipe 401, the valve core 402 being connected to the valve pipe 401 via fins 403, a valve stem 404 disposed on the valve core 402, a valve plate 405 disposed at the lower end of the valve stem 404, and the upper end passing through the valve core 402 and sliding freely thereon, a rocker arm 407 disposed at the upper part of the valve pipe 401, the middle part of the rocker arm 407 being rotatably connected to the valve pipe 401, and the rocker arm 407 being positioned within the valve pipe 401. The upper end of the valve stem 404 is pressed against the lower end of the rocker arm 407. A return spring 406 is provided on the valve stem 404 between the rocker arm 407 and the valve core 402. The upper and lower ends of the return spring 406 are connected to the valve stem 404 and the valve core 402, respectively. When the rocker arm 407 is driven by the connecting rod 6 to rotate counterclockwise, it will drive the valve stem 404 to move downward, thereby opening the valve plate 405. The return spring 406 is used to return the valve plate 405 to the initial position when the rocker arm 407 is reset.

[0023] To facilitate understanding of this utility model, the following is combined with... Figure 1 - Figure 3 The working principle of this solution will be explained in detail:

[0024] When the pressure inside the titanium sponge reactor rises to a certain level, the bellows 502 in the pressure transmission mechanism 5 deforms under pressure, pushing the piston rod 503 upward. The piston rod 503 drives the swing arm 407 to rotate via the connecting rod 6. The swing arm 407 causes the valve rod 404 and valve plate 405 to move downward, opening the exhaust valve 4, and allowing the gas inside the reactor to be discharged through the exhaust valve 4 and exhaust pipe 2. When the pressure inside the reactor drops to a certain level, the bellows 502 returns to its original shape, and the piston rod 503 moves downward under the action of hydraulic oil. This resets the swing arm 407 via the connecting rod 6, and the valve rod 404 and valve plate 405 move upward under the action of the return spring 406, closing the exhaust valve 4.

[0025] By adjusting the position of the counterweight 7 on the connecting rod 6, the torque balance of the connecting rod 6 can be changed, thereby regulating the exhaust pressure. Specifically, the farther the counterweight 7 is from the connection end between the connecting rod 6 and the piston rod 503, the greater the pressure required to trigger the exhaust valve 4 to open; conversely, the closer the counterweight 7 is, the smaller the trigger pressure. In practical applications, by adjusting the position of the counterweight 7 on each connecting rod 6, the exhaust valve 4 can be triggered under different pressures, achieving graded control of the pressure threshold, allowing the gas in the reactor to be released quickly. At the same time, the redundant setting of multiple branches also improves the safety of equipment operation and extends the maintenance cycle.

[0026] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
