Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, and particularly relates to a lead-based reaction kettle pressure stabilizing device. Background Technique

[0002] A reaction kettle is a container used for carrying out chemical reactions. Various chemical raw materials are placed into the kettle, and the raw materials are made to react by heating and stirring the raw materials, etc. When the raw materials to be reacted are acidic or have other corrosiveness, a lead-based reaction kettle is required. Compared with an ordinary reaction kettle, a metal lead is coated on its inner surface as an anti-corrosion layer. Due to the good corrosion resistance of lead, it can protect the internal structure of the reaction kettle from being eroded by chemical substances. At present, lead-based reaction kettles have been widely used in fields such as chemical industry, metallurgy, and nuclear industry.

[0003] When the existing lead-based reaction kettle is in use, various chemical raw materials react in the reaction kettle, generally releasing a large amount of gas or overheating and releasing steam. These gases will increase the pressure in the reaction kettle, and excessive pressure may cause damage to the reaction kettle. Generally, existing ones use methods such as air vents or air outlet valves to exhaust gas, but some chemical reactions have poor reactions at lower pressures and have high requirements for pressure accuracy, and it is necessary to maintain a certain pressure in the reaction kettle. Also, directly exhausting the air will cause heat loss in the reaction kettle. To solve this technical problem, the utility model proposes a lead-based reaction kettle pressure stabilizing device. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a lead-based reaction kettle pressure stabilizing device, which can effectively solve the problems mentioned in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A lead-based reaction kettle pressure stabilizing device includes a reaction kettle body. A plurality of fixed boxes are fixedly connected to the outer surface of the reaction kettle body. An adjusting mechanism is arranged at the bottom of the fixed box. A sliding box is arranged above the adjusting mechanism. The outer surface of the sliding box is slidably connected to the fixed box. A sliding plate is slidably connected to the inner wall of the sliding box. A pressure sensor is installed on the upper surface of the sliding plate, and the upper end of the pressure sensor is in contact with the inner top wall of the sliding plate. A plurality of expansion boxes are fixedly installed on one side of each fixed box. A pressing plate is slidably connected to the inner wall of the expansion box, and an elastic mechanism is arranged on one side of the pressing plate.

[0007] Preferably, it further includes sealing rings. The number of the sealing rings is three. Two of the sealing rings are respectively installed at the upper end and the lower end of the sliding box, and the other sealing ring is installed on the outer surface of the pressing plate.

[0008] Preferably, the outer surface of the sealing ring on the sliding box is slidably connected to the fixed box, and the outer surface of the sealing ring on the pressing plate is slidably connected to the expansion box.

[0009] Preferably, an air outlet is provided at the lower part of the fixed box, and a connecting pipe is installed at the top of the fixed box. The end of the connecting pipe away from the fixed box is connected to the reaction kettle body.

[0010] Preferably, the adjusting mechanism includes a support plate. The upper surface of the support plate is fixedly installed with the fixed box. An expansion rod is installed on the outer surface of the support plate. The telescopic end of the expansion rod penetrates through the fixed box and the sliding box in sequence and is fixedly connected to the sliding plate.

[0011] Preferably, the elastic mechanism includes a sliding rod. One end of the sliding rod is fixedly connected to the pressing plate, and the outer surface of the sliding rod is slidably connected to the expansion box.

[0012] Preferably, a spring is sleeved on the outer surface of the sliding rod. One end of the spring is fixedly connected to the pressing plate, and the other end of the spring is fixedly connected to the expansion box.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, by setting components such as a fixed box and an expansion box, when the pressure in the reaction kettle body reaches a certain level, the adjusting mechanism drives the sliding box to move downward, so that the sliding box moves to the position between the first expansion box and the second expansion box, enabling hot air to enter the interior of the expansion box to reduce the pressure. And so on, making the pressure inside the reaction kettle body tend to be stable, preventing the pressure from being too high or too low. At the same time, the reaction kettle body is insulated by the hot air, preventing the heat of the reaction kettle body from losing too quickly, thereby saving the resources consumed by heating, achieving the effect of recycling hot air, and thus solving the problems that the existing methods of using air outlets or air release valves to exhaust air cannot maintain a certain pressure in the reaction kettle and directly exhausting the air will also cause the heat loss in the reaction kettle.

[0015] In the utility model, by setting components such as an elastic mechanism and a sealing ring, the two sealing rings seal the sliding box and the fixed box to prevent hot air from leaking to the lower part of the sliding plate. After the hot air enters the expansion box, it will exert pressure on the pressing plate, causing the pressing plate to slide into the interior of the expansion box. The spring gives the pressing plate a restoring elastic force, so that the pressing plate will move to the innermost part of the expansion box only when the pressure reaches a certain level, preventing a large amount of hot air from entering suddenly and the pressure dropping rapidly when the sliding box just moves below the expansion box.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, a lead-based reactor pressure stabilizing device includes a reactor body 1. A plurality of fixed boxes 2 are fixedly connected to the outer surface of the reactor body 1. An adjustment mechanism 3 is provided at the bottom of the fixed box 2. The number of adjustment mechanisms 3 is the same as the number of fixed boxes 2. A sliding box 4 is provided above the adjustment mechanism 3. The outer surface of the sliding box 4 is slidably connected to the fixed box 2. A sliding plate 6 is slidably connected to the inner wall of the sliding box 4. A pressure sensor 5 is installed on the upper surface of the sliding plate 6. The upper end of the pressure sensor 5 is in contact with the inner top wall of the sliding plate 6. A controller is installed outside the reactor body 1, which can control all electrical equipment in the device. The pressure sensor 5 can transmit the pressure signal to the controller.

[0024] The adjustment mechanism 3 includes a support plate 301. The upper surface of the support plate 301 is fixedly installed with the fixed box 2. A telescopic rod 302 is installed on the outer surface of the support plate 301. The telescopic end of the telescopic rod 302 penetrates through the fixed box 2 and the sliding box 4 in sequence and is fixedly connected to the sliding plate 6. The telescopic rod 302 can control the up and down movement of the sliding plate 6, thereby driving the up and down movement of the sliding box 4.

[0025] On one side of each fixed box 2, a plurality of expansion boxes 7 are fixedly installed. A pressing plate 8 is slidably connected to the inner wall of the expansion box 7. A elastic mechanism 9 is arranged on one side of the pressing plate 8. The elastic mechanism 9 includes a sliding rod 901. One end of the sliding rod 901 is fixedly connected to the pressing plate 8. The outer surface of the sliding rod 901 is slidably connected to the expansion box 7. A spring 902 is sleeved on the outer surface of the sliding rod 901. One end of the spring 902 is fixedly connected to the pressing plate 8. The other end of the spring 902 is fixedly connected to the expansion box 7. The spring 902 gives the pressing plate 8 a restoring elastic force, so that the pressing plate 8 will move to the innermost part of the expansion box 7 only when the pressure reaches a certain level, preventing the problem that when the sliding box 4 just moves below the expansion box 7, a large amount of hot air enters suddenly and the pressure drops sharply.

[0026] The device further includes three sealing rings 10. Two of the sealing rings 10 are respectively installed at the upper end and the lower end of the sliding box 4. The outer surface of the sealing ring 10 on the sliding box 4 is slidably connected to the fixed box 2. The thickness of the sliding box 4 is larger than that of the expansion box 7. When the sliding box 4 moves downward, the sliding box 4 is sealed with the fixed box 2 through the two sealing rings 10. Only when both sealing rings 10 move to the lower part of the expansion box 7 can the hot air enter the expansion box 7 to prevent the hot air from leaking to the lower part of the sliding plate 6.

[0027] Another sealing ring 10 is installed on the outer surface of the pressing plate 8. The outer surface of the sealing ring 10 on the pressing plate 8 is slidably connected to the expansion box 7. The sealing effect between the pressing plate 8 and the expansion box 7 is increased through the sealing ring 10. An air outlet hole 11 is opened at the lower part of the fixed box 2. A connecting pipe 12 is installed at the top of the fixed box 2. One end of the connecting pipe 12 away from the fixed box 2 is connected to the reaction kettle body 1 to facilitate the hot air inside the reaction kettle body 1 to enter the inside of the fixed box 2.

[0028] It should be noted that during the actual use of the device, the hot gas inside the reactor body 1 enters the inside of the fixed box 2 through the connecting pipe 12 and stays above the sliding box 4. When the pressure increases, there will be a downward force to push the sliding box 4. The inner top wall of the sliding box 4 squeezes the pressure sensor 5, and the pressure sensor 5 transmits the pressure signal to the controller. When the pressure reaches a certain level, the controller controls the telescopic rod 302 to shorten. The telescopic rod 302 drives the sliding plate 6 to move downward, and the sliding plate 6 drives the sliding box 4 to move downward, so that the sliding box 4 moves to the position between the first expansion box 7 and the second expansion box 7, so that the hot gas can enter the inside of the first expansion box 7 to reduce the pressure inside the reactor body 1. By analogy, the pressure inside the reactor body 1 tends to be stable, preventing the pressure from being too high or too low. At the same time, the hot gas is stored inside multiple fixed boxes 2, and the multiple fixed boxes 2 surround the reactor body 1, and the reactor body 1 is insulated by the hot gas inside, preventing the heat of the reactor body 1 from escaping too quickly, thereby saving the resources consumed by heating, achieving the effect of recycling the hot gas.

[0029] The thickness of the sliding box 4 is larger than that of the expansion box 7. When the sliding box 4 moves downward, the sliding box 4 is sealed with the fixed box 2 through two sealing rings 10 to prevent the hot gas from leaking to the lower part of the sliding plate 6. After the hot gas enters the expansion box 7, it will generate pressure on the pressing plate 8, causing the pressing plate 8 to slide into the expansion box 7. The spring 902 gives the pressing plate 8 a restoring elastic force, so that the pressing plate 8 will move to the innermost part of the expansion box 7 only when the pressure reaches a certain level, preventing the problem that when the sliding box 4 just moves below the expansion box 7, a large amount of hot gas enters suddenly and the pressure drops suddenly. A large amount of hot gas can be accommodated by multiple fixed boxes 2 and multiple expansion boxes 7, which is suitable for most reactors on the market. When the reaction time is particularly long, the volume occupied by the hot gas increases, and the sliding box 4 can move below the air outlet 11 to exhaust gas through the air outlet 11 to relieve the pressure.
