Description

Technical Field

[0001] This utility model relates to the technical field of industrial pressure buffer tank devices, and in particular to a pressure buffer tank for an oxygen preparation machine used in the treatment of gold tailings. Background Technology

[0002] Gold tailings require oxidation and cyanidation processes for impurity removal and recovery. Oxygen is the key reaction medium, and its supply stability directly affects processing efficiency and environmental compliance. The gas production of the oxygen generator used for gold tailings treatment fluctuates due to factors such as raw material gas pressure and adsorption tower switching. Furthermore, the oxygen consumption of the reactor changes dynamically with the composition of the tailings, leading to supply and demand imbalances. Therefore, a pressure buffer tank, a pressure-bearing vessel connected in series between the oxygen generator and the reactor, has emerged. By peak shaving and valley filling, it temporarily stores oxygen, storing oxygen to maintain pressure when there is excess gas production and releasing oxygen to replenish pressure when there is insufficient production. It is a key piece of equipment to ensure continuous and efficient tailings treatment.

[0003] Early buffer tanks were welded carbon steel structures, consisting of a cylindrical body, flat end caps, and a single set of inlet and outlet pipes. Relying solely on their own strength to withstand pressure, they had significant drawbacks. Carbon steel corroded in oxygen environments containing cyanide and acidic impurities. The lack of a flow-guiding structure led to oxygen turbulence inside the tank, and tailings dust accumulation blocked the pipes and exacerbated corrosion. Current buffer tanks have been optimized with stainless steel bodies and internal baffles, improved safety accessory structures, stainless steel and titanium alloy composite plates for enhanced corrosion resistance, spiral baffles to reduce turbulence and slag accumulation, and safety valves and pressure gauges for basic monitoring. This extended service life and reduced the risk of blockage. However, the existing structure lacks sufficient explosion-proof performance. The outer shell is mostly a single-layer welded cylinder without dedicated explosion-proof components. Although safety valves control the pressure within design values ​​to prevent conventional leaks, in extreme conditions, the single-layer shell cannot withstand the impact. If the tank ruptures, metal fragments will fly, damaging surrounding equipment and threatening personnel safety. Furthermore, the lack of fragment interception and shock wave guidance devices fails to mitigate secondary injuries. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pressure buffer tank for an oxygen generator used in the treatment of gold tailings, aiming to improve the problem of poor explosion resistance in the existing technology, which would cause shell fragments to fly around and threaten the safety of people in the vicinity once a gas expansion explosion occurs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressure buffer tank for an oxygen generator for gold tailings treatment, comprising an outer shell, a protective mechanism provided on the inner wall of the outer shell, and a control mechanism provided on the outer wall of the outer shell, the control mechanism being used for flow field control; The protective mechanism includes multiple limiting blocks. The outer walls of the multiple limiting blocks are respectively fixedly connected to the upper and lower ends of the inner wall of the outer shell. The inner walls of the multiple limiting blocks are fixedly connected to the same reinforcing layer. The upper and lower ends of the inner wall of the reinforcing layer are fixedly connected to multiple pads. The inner walls of the multiple pads are fixedly connected to the same inner shell. The bottom end of the inner shell is fixedly connected to a soft pad. The bottom of the soft pad is fixedly connected to a chassis. The inner wall of the chassis is provided with a buffer component.

[0006] Preferably, the control mechanism includes a fixed plate, the outer wall of which is fixedly connected to the bottom of the outer wall of the outer casing. Satellite tanks are fixedly connected to the top left and right ends of the fixed plate. A transmission pipe connects to adjacent sides of each of the two satellite tanks. A solenoid valve is installed at the top of each of the two satellite tanks, and a pressure sensor is connected to adjacent sides of each of the two solenoid valves. The buffer assembly includes a compression rod, the outer wall of which is slidably connected to the inner wall of the chassis. Multiple fixing blocks are fixedly connected to the bottom of the outer wall of the compression rod. A spring is installed at the top of the outer wall of the compression rod, and a stabilizing block is fixedly connected to the bottom end of the compression rod.

[0007] Preferably, a label is provided on the bottom front side of the outer casing, a top cover is threaded to the top of the outer casing, and an air vent is connected to the top of the top cover. A bottom shell is fixedly connected to the bottom of the fixed plate, and multiple feet are fixedly connected to the bottom of the bottom shell. A fixed shaft is fixedly connected to the top of the soft pad, and a guide plate is fixedly connected to the outer wall of the fixed shaft. A pressure valve is fixedly connected to the top right side of the outer casing, and a limit plate is fixedly connected to the top of the fixed shaft. An air vent is connected to the top front side of the outer casing, and the adjacent sides of the two pressure sensors are also connected to the left and right sides of the inner wall of the outer casing, respectively. A support column is fixedly connected to the top of each of the multiple feet, and a buffer block is fixedly connected to the top of each of the multiple support columns.

[0008] This utility model has the following beneficial effects: 1. In this utility model, the outer wall of the limiting block is fixed to the upper and lower ends of the inner wall of the outer shell, and the inner wall is fixed to the reinforcing layer. Combined with the inner wall of the reinforcing layer being connected to the inner shell via a pad, a three-layer protective structure is formed, from the outer shell to the reinforcing layer and then to the inner shell. This can constrain the deformation of the inner shell and the diffusion of fragments during an explosion. The bottom end of the inner shell is connected to the chassis via a soft pad. In conjunction with the buffer component on the inner wall of the chassis, it can absorb the impact energy generated by the explosion, prevent fragments from flying at high speed after the outer shell breaks, and improve the explosion-proof performance of the equipment.

[0009] 2. In this utility model, the outer wall of the fixed plate is fixed to the bottom of the outer wall of the outer shell, and the satellite tanks are fixed to the top left and right ends of the plate. With the transmission pipes connected to the adjacent sides of the satellite tanks, and the pressure sensor connected to the adjacent side of the solenoid valve at the top of the satellite tanks, a coordinated control structure of the main tank and satellite tanks is formed. This realizes the diversion or return of oxygen between the main tank and the satellite tanks, adjusts the flow field distribution, solves the problem that the existing technology cannot control the flow field, and ensures stable gas supply.

[0021] Working principle: In the initial stage of the explosion, the enormous impact force generated instantaneously inside the tank first acts on the inner shell 204. Since the inner shell 204 is connected to the reinforcing layer 202 through multiple pads 201, the pads 201 can absorb part of the impact energy, preventing the impact force from being directly transmitted to the outer structure. At the same time, the reinforcing layer 202 is fixed to the inner wall of the outer shell 1 through the limiting block 203, forming a three-layer protective structure from the outer shell 1 to the reinforcing layer and then from 202 to the inner shell 204. This effectively restricts the deformation range of the inner shell 204, preventing it from rupturing instantly and generating a large number of fragments. If the impact force breaks through the initial buffer between the inner shell 204 and the reinforcing layer 202, it is transmitted downwards to the soft pad 20. At 6 o'clock, to reduce the impact on the chassis 205, the compression rod 2071 slides down the inner wall of the chassis 205 after being impacted, and the spring 2073 at the top of the outer wall is compressed. The elastic deformation of the spring 2073 absorbs the vertical impact energy. The fixing block 2072 can limit the sliding range of the compression rod 2071 to prevent excessive displacement and structural failure. The stabilizing block 2074 can enhance the support of the bottom of the compression rod 2071 and prevent the chassis 205 from deforming due to impact. It can confine the broken metal fragments in the interlayer gap and prevent the fragments from flying to the outside at high speed, thereby eliminating the safety threat to the surrounding personnel and achieving the core goal of explosion-proof protection.

[0022] During normal operation, the fixed plate 301 serves as a basic support, stably fixing the satellite tanks 302 to both sides of the bottom of the outer shell 1, forming a multi-tank collaborative structure of the main tank and the two satellite tanks 302. The pressure sensor 305 monitors the oxygen pressure in the main tank and the satellite tanks 302 in real time. When the flow field in the main tank becomes unstable due to fluctuations in the oxygen generator's output or changes in the oxygen consumption of the reactor, the sensor transmits a signal to the solenoid valve 304. If the pressure in the main tank is too high, the solenoid valves 304 on both sides automatically open, and some of the oxygen in the main tank is diverted to the satellite tanks 302 through the transmission pipe 303. 2. Temporary storage disperses the airflow pressure in the main tank, preventing the generation of local eddies. If the pressure in the main tank is too low, the solenoid valve 304 opens in reverse, and the oxygen stored in the satellite tank 302 flows back to the main tank through the transmission pipe 303 to replenish the airflow and stabilize the flow field in the main tank. Finally, the stabilized airflow after regulation is delivered to the reactor from the outlet 6 at the top of the top cover 5. The bottom shell 7 and the foot 8 provide stable support to prevent equipment vibration from aggravating the flow field turbulence. The label 4 can mark parameters for precise control, realizing dynamic and precise control of the flow field in the buffer tank and ensuring the stability of the gas supply.
