[0002] A reaction vessel is a comprehensive reaction container. Through structural design and parameter configuration, it can achieve the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. During the use of the reaction vessel, a pressure relief device needs to be installed to prevent excessive pressure inside the reaction vessel.

[0003] In use, the existing pressure relief structure of the reactor uses the pressure inside the reactor to push up the rubber plug in the pressure relief structure, and the excess gas is discharged through the gap between the rubber plug and the pressure relief structure.

[0004] When existing pressure relief structures for reactors are in use, chemical reactions may occur inside the reactors. Multiple reactors of the same type may be arranged with different chemical reactions. Different chemical reactions may produce different substances and other substances, resulting in different pressures on each reactor. The pressure relief structure may not be able to adjust its own pressure balance value, which may lead to the failure of the pressure relief structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pressure relief structure for a reactor, which solves the problem that existing pressure relief structures may fail to adjust their own pressure balance values ​​during use because chemical reactions may occur inside the reactor. This is because multiple reactors of the same type may be arranged to carry out different chemical reactions, and the substances and other substances obtained from different chemical reactions may be different, resulting in different pressures on each reactor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure relief structure for a reaction vessel, comprising a reaction vessel body, a pressure relief seat connected to the top of the reaction vessel body, through grooves on both sides of the outer wall of the pressure relief seat, a sealing plug inside the pressure relief seat, a spring sheet abutting the top of the sealing plug, and the top of the spring sheet abutting the top of the inner wall of the pressure relief seat. An adjustment assembly is installed between the spring sheet and the pressure relief seat. The adjustment assembly includes: two adjustment seats, rotatably connected to both sides of the spring sheet and inserted into the inner walls of the two through grooves; two adjustment grooves, each located on the top of one of the two adjustment seats; two adjustment plates, each inserted into the inner walls of the two adjustment grooves; three limiting grooves on one side, extending from top to bottom on the side wall of the adjustment plate; and a limiting unit located on the top of the pressure relief seat. The spring force of the spring sheet changes through the cooperation of the adjustment plates with the adjusting grooves on the top of the adjustment seats.

[0007] Preferably, the limiting unit includes: a fixed base, fixedly connected to the top of the pressure relief seat; a spring, disposed inside the fixed base; two connecting rods, both disposed inside the fixed base and fixedly connected to both ends of the spring; and two limiting rods, each fixedly connected to the end of the two connecting rods away from the spring, and inserted into both sides of the outer wall of the fixed base, extending to the inner wall of the limiting groove; wherein, through the cooperation of the spring inside the fixed base and the two connecting rods, the limiting rod is inserted into the inner wall of the limiting groove, thereby fixing the adjusting plate.

[0008] Preferably, the outer wall of the pressure relief seat is provided with exhaust holes on both sides, and is located below the two through slots respectively.

[0011] Beneficial effects

[0012] This invention provides a pressure relief structure for a reaction vessel. It offers the following advantages: This pressure relief structure, through the cooperation of the adjusting seat, adjusting groove, adjusting plate, and limiting groove, achieves a change in the internal pressure balance value of the pressure relief structure. This solves the problem that existing pressure relief structures for reaction vessels often fail to adjust their own pressure balance value due to the chemical reactions occurring inside the vessel. Multiple similar reaction vessels may be arranged for different chemical reactions, resulting in different substances and other properties, leading to varying pressures on each vessel. This can cause the pressure relief structure to malfunction.

[0013] By coordinating the fixed seat, spring, connecting rod, and limiting rod, the adjusting plate is fixed, solving the problem that existing pressure relief structures in reactors may not allow operators to easily adjust the pressure balance value of the pressure relief structure itself, resulting in the inability to adjust the pressure relief structure in a timely manner according to the gases produced by different reactions. This situation may increase the risk factor of the work. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0021] When existing pressure relief structures for reactors are in use, chemical reactions may occur inside the reactors. Multiple reactors of the same type may be arranged to carry out different chemical reactions. The substances and other substances obtained from different chemical reactions may be different, resulting in different pressures on each reactor. The pressure relief structure may not be able to adjust its own pressure balance value, which may lead to the failure of the pressure relief structure.

[0022] In view of this, the present invention provides a pressure relief structure for a reactor. This pressure relief structure, through the cooperation of the adjusting seat, adjusting groove, adjusting plate and limiting groove, realizes the change of the internal pressure balance value of the pressure relief structure. It solves the problem that in the use of existing reactor pressure relief structures, due to the chemical reaction that occurs inside the reactor, multiple reactors of the same type may be arranged with different chemical reactions, and the substances and other substances obtained from different chemical reactions may be different, resulting in different pressures on each reactor. The pressure relief structure may not be able to adjust its own pressure balance value, which may lead to the failure of the pressure relief structure.

[0023] Example 1, by Figure 1-4 As can be seen, the pressure relief structure of the reactor in this case includes the reactor body 1. It is understood that the reactor body 1 described in this case is not the pressure relief structure of the reactor in this case. For the convenience of describing the installation position and structural relationship of the pressure relief structure, it is described and recorded here. The specific type and model of the reactor body 1 are not limited, as long as it meets the use and installation conditions of the pressure relief structure of the reactor. Of course, other structures described in this case should not affect the configuration of the stirring, packing, discharging and heating devices that the reactor body 1 may have. Therefore, the pressure relief structure of the reactor can be installed in a suitable position of the reactor body 1 according to the requirements. The top of the reactor body 1 is connected to a pressure relief seat 2. The outer walls of the pressure relief seat 2 are provided with through grooves 22 on both sides. The pressure relief seat 2 is internally equipped with a sealing plug 3, the top of which abuts against a spring 4. The top of the spring 4 abuts against the top of the inner wall of the pressure relief seat 2. An adjustment assembly 5 is installed between the spring 4 and the pressure relief seat 2. The adjustment assembly 5 includes: two adjustment seats 51, which are rotatably connected to both sides of the spring 4 and inserted into the inner walls of the two through slots 22; two adjustment slots 52, which are respectively opened on the top of the two adjustment seats 51; two adjustment plates 53, which are respectively inserted into the inner walls of the two adjustment slots 52; three limiting slots 54 are provided on one side, which are opened from top to bottom on the side wall of the adjustment plate 53; and a limiting unit 55 is located on the top of the pressure relief seat 2. The spring force of the spring 4 changes by the cooperation between the adjustment plate 53 and the adjustment slots 52 on the top of the adjustment seat 51.

[0024] In the specific implementation process, it is worth noting that the bottom of the pressure relief seat 2 is cylindrical, and the top is a square prism. The top of the square prism is fixedly connected to a sealing cover by four bolts. A sealing gasket is provided at the bottom of the sealing cover. A sealing gasket is also provided between the pressure relief seat 2 and the reactor body 1 to prevent gas leakage inside the reactor body 1. The inner wall of the pressure relief seat 2 is provided with a slope, which fits against the slope provided at the bottom of the sealing plug 3. The spring 4 consists of two parts, which are rotatably connected by a pin. The two ends of the pin are installed on pin seats. The pin seats on both sides are fixed together with the adjusting seat 51. The cross-section of the adjusting seat 51 is "7" shaped, and the top is movably connected to the through groove 22. The regulating groove 52 has a trapezoidal cross-section and an inclined surface on the side near the pressure relief seat 2. It cooperates with the regulating plate 53 to allow the regulating seat 51 to move. The bottom cross-section of the regulating plate 53 is semi-circular to facilitate better cooperation with the inclined surface of the regulating groove 52. The top of the regulating plate 53 is equipped with a handle with a horizontal bar for easy gripping. There are six limiting grooves 54, three on one side and six in total. The overall shape is quadrilateral and can cooperate with the limiting unit 55. Through the cooperation between the regulating seat 51, regulating groove 52, regulating plate 53 and limiting groove 54, the pressure balance value inside the pressure relief structure is changed, thereby expanding the application range of the pressure relief structure of the reactor.

[0025] Furthermore, the limiting unit 55 includes: a fixed base 551, fixedly connected to the top of the pressure relief seat 2; a spring 552, disposed inside the fixed base 551; two connecting rods 553, each disposed inside the fixed base 551 and fixedly connected to both ends of the spring 552; and two limiting rods 554, each fixedly connected to the end of the two connecting rods 553 away from the spring 552, and inserted into both sides of the outer wall of the fixed base 551, extending to the inner wall of the limiting groove 54; wherein, through the cooperation of the spring 552 inside the fixed base 551 and the two connecting rods 553, the limiting rods 554 are inserted into the inner wall of the limiting groove 54, thereby fixing the adjusting plate 53.

[0026] In the specific implementation process, it is worth noting that the fixed seat 551 is generally rectangular with an internal space and an open bottom, with openings on both sides. The spring 552 is made of carbon spring steel, and the elastic coefficient of the spring 552 is selected according to actual needs to meet the working requirements. The connecting rod 553 is a horizontally placed quadrangular prism with a cross-section larger than the openings on both sides of the fixed seat 551. The openings on both sides of the fixed seat 551 limit the connecting rod 553. The limiting rod 554 is also generally a horizontally placed quadrangular prism. The front and back of the limiting rod 554 are provided with auxiliary rods, which make it easier for the operator to pull the limiting rod 554 to leave the interior of the limiting groove 54. The end of the limiting rod 554 is also provided with a bevel to facilitate the entry of the limiting rod 554 into the interior of the limiting groove 54. Through the cooperation between the fixed seat 551, spring 552, connecting rod 553 and limiting rod 554, the adjusting plate 53 is fixed, thereby improving the structural stability of the pressure relief structure of the reactor.

[0027] Furthermore, both sides of the outer wall of the pressure relief seat 2 are provided with exhaust holes 21, which are located below the two through slots 22 respectively. Both sides of the outer wall of the pressure relief seat 2 are fixedly connected with fixing plates 24, which are located above the two through slots 22 respectively. The inner wall of the fixing plate 24 is sleeved on the outer wall of the adjusting plate 53.

[0028] In the specific implementation process, it is worth noting that there are two exhaust holes 21 with circular cross-sections and arranged in parallel, and two fixing plates 24 are provided to limit the adjustment plate 53, thereby improving the working stability of the pressure relief structure of the reactor.

[0029] Specifically, when the pressure inside the reactor body 1 is too high, the gas produced by the reaction will enter its interior through the hole at the bottom of the pressure relief seat 2. Due to the pressure, the gas exerts an upward force on the bottom of the sealing plug 3, pushing the sealing plug 3 upward. The sealing plug 3 transmits the force to the spring 4 located at its top. The spring 4 bends upward under the force, and at this time, a gap appears between the bottom of the sealing plug 3 and the inner wall of the pressure relief seat 2. The gas enters the interior of the pressure relief seat 2 through the gap and flows to the outside of the reactor body 1 through the exhaust port 21, achieving the purpose of pressure relief and improving the safety of the reactor. When it is necessary to relieve the pressure of the gas produced by different reactions, the operator needs to change the elastic force of the spring 4. First, the operator places one hand on the auxiliary rods on both sides of the outer wall of the limit rod 554 on one side and pulls the limit rod 554 towards the fixed seat 551. The limit rod 554 drives the connecting rod 553 to move, and the connecting rod 553 compresses the spring 552. At this point, the limiting rod 554 leaves the inside of the limiting groove 54. With the other hand, pinch the handle at the top of the adjusting plate 53 and apply downward force. The adjusting plate 53 drives the adjusting seat 51 to move through the adjusting groove 52. The adjusting seat 51 drives the spring 4 to move. When the middle limiting groove 54 corresponds to the limiting rod 554, release the hand on the auxiliary rod. The spring 552 rebounds, driving the connecting rod 553 to move away from the spring 552. The connecting rod 553 drives the limiting rod 554 to move. The limiting rod 554 returns to the middle limiting groove 54 of the adjusting plate 53. The operation on the other side is the same. At this point, the effect of adjusting the elastic force of the spring 4 is achieved. If it is still not possible to match the current gas pressure, the limiting rod 554 can be inserted into the top limiting groove 54 in the same way as above. At this point, the adjusting plate 53 is located at the bottom of the inner wall of the adjusting groove 52, thereby changing the pressure balance value inside the pressure relief structure of the reactor and expanding the application range of the pressure relief structure of the reactor.

[0030] Example 2, by Figure 1-4 It can be seen that a sealing seat 23 is fixedly connected to the outer wall of the pressure relief seat 2, and the bottom of the sealing seat 23 is fixedly connected to the top of the reactor body 1;

[0031] In the specific implementation process, it is worth noting that the sealing seat 23 is in the shape of a ring. Sealing gaskets are provided between the sealing seat 23, the pressure relief seat 2 and the reactor body 1 to prevent air leakage between the pressure relief seat 2 and the reactor body 1, thereby improving the stability of the pressure relief structure of the reactor.

[0032] Furthermore, sliders 31 are fixedly connected to both sides of the sealing plug 3, and the outer wall of the slider 31 away from the sealing plug 3 is slidably engaged with the inner wall of the pressure relief seat 2.

[0033] In the specific implementation process, it is worth noting that the slider 31 is provided with two sliding grooves that cooperate with the inner wall of the pressure relief seat 2 to limit the movement of the sealing plug 3, so as to prevent the sealing plug 3 from having problems when the pressure relief structure is needed, thereby improving the operational stability of the pressure relief structure of the reactor.

[0034] Specifically, firstly, sealing gaskets are provided between the sealing seat 23, the pressure relief seat 2, and the reactor body 1 to prevent air leakage between the pressure relief seat 2 and the reactor body 1. Secondly, the slider 31 limits the movement of the sealing plug 3 to prevent problems with the sealing plug 3 when the pressure relief structure is needed, thereby improving the operational stability of the pressure relief structure of the reactor.

Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
