Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of pesticide production equipment, concretely relates to a chlorfenapyr production line automatic feeding device. BACKGROUND

[0002] Chlorfenapyr is a widely used insecticide in the field of agriculture, and its production process involves the accurate proportioning and feeding of various chemical raw materials. The traditional manual feeding method has the problems of low efficiency, inaccurate raw material proportioning caused by operation errors, safety hazards, etc., especially when handling toxic or corrosive raw materials, the risk is higher.

[0003] In order to improve production efficiency and safety, automatic feeding devices are gradually introduced into the production line of chlorfenapyr. The existing automatic feeding devices usually include raw material storage tanks, reaction kettles and feeding assemblies connecting the two. However, these devices still have some problems in actual application. The pump body in the feeding assembly may cause unstable raw material delivery due to pressure fluctuations when delivering raw materials, thereby affecting the uniformity of the reaction and the quality of the product. The existing pressure compensation mechanism is often complex and has high maintenance cost, which is difficult to meet the needs of large-scale production.

[0004] More seriously, when the equipment is in emergency shutdown, the materials transmitted before and after the feeding assembly will continue to flow forward or produce pressure impact due to inertia. This inertial force not only may cause the pressure in the pipeline to increase suddenly, damaging the sealing assembly or the connection part of the pipeline, but also may cause mechanical damage to the pump body, reaction kettle and other key equipment, and even cause safety accidents such as leakage. The existing automatic feeding devices do not fully consider this problem, lack effective inertia force buffering or pressure release mechanism, resulting in high failure risk of the equipment in emergency shutdown.

[0005] In addition, the existing automatic feeding device often needs to replace or adjust the equipment parts when handling raw materials with different viscosity, density or corrosivity, which increases the production cost and downtime. At the same time, for some volatile or environmentally sensitive raw materials, the sealing performance of the existing device may not be sufficient, which may cause loss of raw materials or environmental pollution.

[0006] In the production process, accurate metering and uniform mixing of raw materials are also a key problem. The existing device may not meet the high-precision feeding requirements, especially when handling trace additives. In addition, some devices are difficult to realize real-time monitoring and adjustment in continuous production process, and cannot respond to changes in production parameters in time, affecting the consistency of product quality. INVENTION CONTENTS

[0007] The utility model provides a kind of chlorfenapyr production line automatic feeding device to solve at least one of the above technical problems.

[0008] The utility model discloses a technical scheme which adopts the following technical scheme:

[0010] Further, the application also proposes that the initial position of the sealing sleeve is located at 1 / 2 length of the sealing tube.

[0011] Further, the application also proposes that the inner wall of the sealing sleeve is fixedly connected with a fixed shaft, a sealing piston is slidably connected on the fixed shaft, when the sealing sleeve slides to the maximum value of the depth of sleeve connection with the sealing tube, the sealing piston just inserts into the sealing tube, the end of the fixed shaft is fixedly connected with a limit plate, the second elastic member is fixedly connected between the sealing piston and the limit plate, the diameter of the sealing piston is the same as the inner diameter of the sealing tube, and the diameter of the limit plate is smaller than the inner diameter of the sealing tube.

[0012] Further, the application also proposes that one end of the sealing piston towards the sealing tube is provided with a conical boss.

[0013] Further, the application also proposes that the outer wall of the sealing tube is provided with two sets of annular limiting bosses at both ends, the end of the sealing sleeve is provided with an annular sealing boss, and the annular sealing boss is located between the two sets of annular limiting bosses and is slidably connected with the outer wall of the sealing tube.

[0014] Further, the application also proposes that the first elastic member is arranged between the annular sealing boss and the annular limiting boss.

[0015] Further, the application also proposes that the inner side of the annular sealing boss, the outer side of the annular limiting boss inside the sealing sleeve, and the outer side of the sealing piston are all provided with sealing rubber rings.

[0016] Further, the application also proposes that one end of the sealing tube away from the sealing sleeve is provided with a threaded connection pipe, the feed pipe and the discharge pipe are both provided with a connecting port for connecting the threaded connection pipe, the outer end of the feed pipe is provided with a first flange, and the outer end of the discharge pipe is provided with a second flange.

[0017] Further, the application also proposes that the first pressure gauge is arranged on the feed pipe, and the second pressure gauge is arranged on the discharge pipe.

[0018] Further, the application also proposes that the raw material storage tank is provided with a feeding pipe for connecting a feeding pipe, and the reaction kettle is provided with a feeding pipe for connecting a discharging pipe.

[0019] Due to the adoption of the above technical scheme, the application has the following beneficial effects:

[0020] 1. By arranging the pump body and the pressure compensation assembly in the feeding assembly, the stability and accuracy of the raw material conveying are ensured. When the equipment is running, the sealing sleeve can slide when the pressure fluctuates, thereby absorbing the pressure fluctuation and ensuring the stability of the raw material conveying.

[0021] When the equipment is in emergency shutdown, the sealing sleeve and the first elastic member can absorb the inertial force of the material, avoiding damage to the equipment caused by pressure impact. By arranging the pressure compensation assembly, the influence of pressure fluctuation on the raw material conveying is effectively alleviated.

[0022] Meanwhile, the sealing sleeve and the elastic buffer structure absorb the inertial force when the equipment is in emergency shutdown, avoiding damage to the equipment caused by pressure impact. The device has a simple structure and is easy to maintain, is suitable for large-scale industrial production, and improves the safety and reliability of the equipment.

[0023] 2. The initial position of the sealing sleeve is located at 1 / 2 length of the sealing pipe. This design can effectively provide good sealing effect in the initial state, while allowing the sealing sleeve to slide appropriately in the middle of the sealing pipe to the two sides to meet the needs of different pressure changes and material flow on both sides of the pump. In this way, the working state of the sealing assembly can be flexibly adjusted without affecting the sealing effect, thereby improving the stability and reliability of the feeding device.

[0024] When the sealing sleeve is located at 1 / 2 length of the sealing pipe, sufficient sealing pressure can be provided in the initial stage to prevent material leakage. At the same time, when the system pressure changes, the sealing sleeve can slide within the sealing pipe to adapt to the pressure change, avoiding sealing failure caused by pressure fluctuation. This design not only improves the adaptability of the sealing assembly, but also simplifies the structure and reduces the maintenance cost.

[0025] 3. By designing the sealing sleeve, the fixed shaft, the sealing piston and the second elastic member, the problem of pressure impact caused by material inertia force when the traditional automatic feeding device is in emergency shutdown is solved. The sealing piston is slidably connected in the sealing sleeve through the fixed shaft, and is inserted into the sealing pipe when the sealing sleeve slides to the maximum depth, forming an effective seal. At the same time, the design of the limiting plate and the second elastic member can absorb a large inertial force at the moment of shutdown, avoiding damage to the equipment caused by a large pressure impact.

[0026] 4. The sealing problem between the sealing piston and the inner wall of the sealing tube is solved by providing a tapered boss at one end of the sealing piston towards the sealing tube. The design of the tapered boss can ensure that the sealing piston achieves good sealing effect when inserted into the sealing tube, thereby avoiding leakage of raw materials or pressure loss.

[0027] The tapered boss is designed in a tapered shape, which can gradually increase the contact area when the sealing piston is inserted into the sealing tube, ensuring the sealing between the sealing piston and the inner wall of the sealing tube. At the same time, the presence of the tapered boss can reduce the resistance when the sealing piston is inserted into the sealing tube, ensuring that the sealing piston can be smoothly inserted into the sealing tube, further improving the sealing effect.

[0028] 5. Two sets of annular limiting bosses are provided at both ends of the outer wall of the sealing tube, and an annular sealing boss is provided at the end of the sealing sleeve. The annular sealing boss is located between the two sets of annular limiting bosses and is in sliding connection with the outer wall of the sealing tube. This design limits the sliding range of the sealing sleeve through the two annular limiting bosses, ensuring that the sealing sleeve always remains on the sealing tube during sliding and cannot slide out of the sealing tube. At the same time, the annular sealing boss is in sliding connection with the outer wall of the sealing tube, which can provide good sealing effect when the sealing sleeve slides, preventing material leakage.

[0029] 6. The first elastic member is used to provide elastic support between the annular sealing boss and the annular limiting boss, so as to effectively buffer pressure fluctuations when the sealing sleeve slides. This design can ensure that the raw materials remain stable during transportation, avoiding uneven transportation caused by pressure changes. By providing the first elastic member, the inertial force generated by the emergency shutdown of the equipment can be absorbed and buffered, avoiding damage to the equipment.

[0030] 7. Sealing rubber rings are provided inside the annular sealing boss, outside the annular limiting boss inside the sealing sleeve, and outside the sealing piston, to ensure the sealing performance between the parts during operation of the device. These sealing rubber rings can effectively prevent raw material leakage, maintain stable pressure inside the system, and thus improve the accuracy and stability of the feeding.

In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0043] Referring to Figures 1-4 The application provides a kind of imidacloprid production line automatic feeding device, including raw material storage tank 1, reaction kettle 2, raw material storage tank 1 with reaction kettle 2 between being equipped with feeding assembly. Feeding assembly includes pump body 3, the input end and output end of pump body 3 are equipped with feed pipe 31 and discharge pipe 32, feed pipe 31 and discharge pipe 32 are all equipped with pressure compensation assembly. Pressure compensation assembly is communicated with the seal tube 4 of feed pipe 31 or discharge pipe 32 inner cavity, the outer wall of seal tube 4 is slidably connected with sealing sleeve 5, first elastic piece 43 is arranged between seal tube 4 and sealing sleeve 5.

[0044] Those skilled in the art can understand that in the production process of imidacloprid, the accurate feeding and conveying stability of raw materials is the key to ensure product quality. By setting pump body 3 and pressure compensation assembly in the feeding assembly, the stability and accuracy of raw material conveying are ensured. When the equipment is running, the sealing sleeve 5 can slide when the pressure fluctuates, thereby absorbing the pressure fluctuation and ensuring the stability of the raw material conveying. When the equipment is in emergency shutdown, the sealing sleeve 5 and the first elastic piece 43 can absorb the inertial force of the material, avoiding damage to the equipment caused by pressure impact. By setting the pressure compensation assembly, the influence of pressure fluctuation on raw material conveying is effectively alleviated. At the same time, the sealing sleeve 5 and the elastic buffer structure absorb the inertial force when the equipment is in emergency shutdown, avoiding damage to the equipment caused by pressure impact. The device has simple structure, easy maintenance, is suitable for large-scale industrial production, and improves the safety and reliability of the equipment.

[0045] Compared with the prior art, the automatic feeding device of the present application has a more simple structure in design, and has low maintenance cost. The pressure compensation mechanism in the prior art is complex and has high maintenance cost, while the present application simplifies the structure design and reduces the maintenance cost by setting the sliding sealing sleeve 5 and the elastic piece. In addition, the present application can effectively absorb the inertial force of the material when the equipment is in emergency shutdown, avoiding damage to the equipment caused by pressure impact, and improving the safety and reliability of the equipment.

[0046] The application solves the problem of unstable raw material conveying by arranging a pump body 3, a feeding pipe 31, a discharging pipe 32 and a pressure compensation assembly in the feeding assembly. The sealing pipe 4 in the pressure compensation assembly is in communication with the inner cavities of the feeding pipe 31 or the discharging pipe 32, the outer wall of the sealing pipe 4 is slidingly connected with a sealing sleeve 5, and the first elastic member 43 is arranged between the sealing pipe 4 and the sealing sleeve 5. The sealing sleeve 5 can slide when the pressure fluctuates, thereby absorbing the pressure fluctuation and ensuring the stability of the raw material conveying. When the equipment is in emergency shutdown, the sealing sleeve 5 and the first elastic member 43 can absorb the inertial force of the material, thereby avoiding damage to the equipment caused by pressure impact. Therefore, the device of the application not only improves the production efficiency and safety, but also reduces the maintenance cost, and is suitable for large-scale industrial production.

[0047] As a preferred example of the above embodiment, refer to Figure 2 The initial position of the sealing sleeve 5 is located at 1 / 2 of the length of the sealing pipe 4. The initial position of the sealing sleeve 5 at 1 / 2 of the length of the sealing pipe 4 can effectively provide good sealing effect in the initial state, while allowing the sealing sleeve 5 to slide appropriately to both sides in the middle of the sealing pipe 4 to meet the needs of different pressure changes and material flow on both sides of the pump. In this way, the working state of the sealing assembly can be flexibly adjusted without affecting the sealing effect, thereby improving the stability and reliability of the feeding device.

[0048] When the sealing sleeve 5 is located at 1 / 2 of the length of the sealing pipe 4, sufficient sealing pressure can be provided in the initial stage to prevent material leakage. At the same time, when the system pressure changes, the sealing sleeve 5 can slide in the sealing pipe 4 to adapt to the pressure change and avoid sealing failure caused by pressure fluctuation. This design not only improves the adaptability of the sealing assembly, but also simplifies the structure and reduces the maintenance cost.

[0049] As a preferred embodiment of the application, refer to Figure 1 and Figure 2 The inner wall of the sealing sleeve 5 is fixedly connected with a fixed shaft 6, the fixed shaft 6 is slidingly connected with a sealing piston 61, when the sealing sleeve 5 slides to the maximum depth of the sealing pipe 4, the sealing piston 61 is just inserted into the sealing pipe 4, the end of the fixed shaft 6 is fixedly connected with a limiting plate 62, the second elastic member 7 is fixedly connected between the sealing piston 61 and the limiting plate 62, the diameter of the sealing piston 61 is the same as the inner diameter of the sealing pipe 4, and the diameter of the limiting plate 62 is smaller than the inner diameter of the sealing pipe 4.

[0050] By the design of the sealing sleeve 5, the fixed shaft 6, the sealing piston 61 and the second elastic member 7, the problem of pressure impact caused by material inertia force during emergency shutdown of the equipment in the traditional automatic feeding device is solved. The sealing piston 61 is connected to the sealing sleeve 5 through the fixed shaft 6, and is inserted into the sealing pipe 4 when the sealing sleeve 5 slides to the maximum depth, forming an effective seal. At the same time, the design of the limiting plate 62 and the second elastic member 7 can absorb a large inertia force at the moment of shutdown, avoiding damage to the equipment caused by a large pressure impact.

[0051] The end of the sealing piston 61 towards the sealing pipe 4 is provided with a conical boss 611 to facilitate better insertion into the sealing pipe 4 and ensure sealing effect. The limiting plate 62 at the end of the fixed shaft 6 has a diameter smaller than the inner diameter of the sealing pipe 4, so that the limiting plate 62 does not affect the sealing effect during the sliding process of the fixed shaft 6. The setting of the second elastic member 7 further enhances the absorption capacity of the pressure impact.

[0052] The automatic feeding device of the present application not only effectively alleviates the influence of pressure fluctuation on raw material conveying, ensuring the stability and accuracy of feeding, but also absorbs material inertia force during emergency shutdown of the equipment, avoiding damage to the equipment caused by pressure impact. The device has a simple structure and is easy to maintain, suitable for large-scale industrial production, and significantly improves the safety and reliability of the equipment.

[0053] As a preferred example of the above embodiment, with reference to Figure 2 , the end of the sealing piston 61 towards the sealing pipe 4 is provided with a conical boss 611.

[0054] By providing a conical boss 611 at the end of the sealing piston 61 towards the sealing pipe 4, the sealing problem between the sealing piston 61 and the inner wall of the sealing pipe 4 is solved. The design of the conical boss 611 can ensure that the sealing piston 61 achieves good sealing effect when inserted into the sealing pipe 4, thereby avoiding leakage of raw materials or pressure loss.

[0055] The conical boss 611 is designed in a conical shape, which can gradually increase the contact area when the sealing piston 61 is inserted into the sealing pipe 4, ensuring the sealing between the sealing piston 61 and the inner wall of the sealing pipe 4. At the same time, the presence of the conical boss 611 can reduce the resistance when the sealing piston 61 is inserted into the sealing pipe 4, ensuring that the sealing piston 61 can be smoothly inserted into the sealing pipe 4, further improving the sealing effect.

[0056] As a preferred embodiment of the conical boss 611, the conical boss 611 can be made of wear-resistant materials to improve its service life and sealing effect. In addition, the size and angle of the conical boss 611 can be adjusted according to actual needs to adapt to different sealing requirements.

[0057] As a preferred embodiment of the present application, with reference toFigure 2 and Figure 3 The outer wall of the sealing pipe 4 is provided with two sets of annular limiting bosses 42 at both ends, and the end of the sealing sleeve 5 is provided with an annular sealing boss 51, which is located between the two sets of annular limiting bosses 42 and is in sliding connection with the outer wall of the sealing pipe 4.

[0058] By setting the annular limiting bosses 42 at both ends of the outer wall of the sealing pipe 4 and the annular sealing boss 51 at the end of the sealing sleeve 5, the sliding range of the sealing sleeve 5 on the sealing pipe 4 can be effectively limited, ensuring that the sealing sleeve 5 does not come off the sealing pipe 4 during sliding. In addition, the annular sealing boss 51 is in sliding connection with the outer wall of the sealing pipe 4, which can maintain good sealing performance when the sealing sleeve 5 slides, preventing material leakage.

[0059] The outer wall of the sealing pipe 4 is provided with two sets of annular limiting bosses 42 at both ends, and the end of the sealing sleeve 5 is provided with an annular sealing boss 51, which is located between the two sets of annular limiting bosses 42 and is in sliding connection with the outer wall of the sealing pipe 4. This design limits the sliding range of the sealing sleeve 5 through the two annular limiting bosses 42, ensuring that the sealing sleeve 5 always remains on the sealing pipe 4 during sliding and does not slide out of the sealing pipe 4. At the same time, the annular sealing boss 51 is in sliding connection with the outer wall of the sealing pipe 4, which can provide good sealing effect when the sealing sleeve 5 slides, preventing material leakage.

[0060] Further, the first elastic member 43 is arranged between the annular sealing boss 51 and the annular limiting boss 42.

[0061] The first elastic member 43 is used to provide elastic support between the annular sealing boss 51 and the annular limiting boss 42, so as to effectively buffer pressure fluctuations when the sealing sleeve 5 slides. This design can ensure that the raw materials remain stable during transportation, avoiding uneven transportation caused by pressure changes. By setting the first elastic member 43, the inertial force generated by emergency shutdown of the equipment can be absorbed and buffered, avoiding damage to the equipment.

[0062] Specifically, the first elastic member 43 and the second elastic member 7 can take various forms, such as springs or other materials with elastic properties. The spring can be selected as a spiral spring or a wave spring, which is designed and selected according to actual needs. The rubber pad can be cut and installed according to the size of the sealing sleeve 5 and the sealing pipe 4. In addition, other materials with good elasticity and durability can also be selected as the first elastic member 43 according to actual application conditions.

[0063] The technical scheme of the present application can effectively solve the problems of unstable raw material conveying and pressure impact during emergency shutdown of the equipment in the prior art. Compared with the prior art, the device of the present application has a simple structure, is convenient to maintain, can significantly improve the stability and safety of the production line, and is suitable for large-scale industrial production.

[0064] Furthermore, the inner side of the annular sealing boss 51 and the outer side of the annular limiting boss 42 inside the sealing sleeve 5, and the outer side of the sealing piston 61 are all provided with sealing rubber rings.

[0065] The sealing rubber rings are arranged on the inner side of the annular sealing boss 51, the outer side of the annular limiting boss 42 inside the sealing sleeve 5, and the outer side of the sealing piston 61 to ensure the sealing performance between the parts during operation of the device. These sealing rubber rings can effectively prevent raw material leakage, maintain the stability of the internal pressure of the system, and thus improve the accuracy and stability of the feeding.

[0066] The sealing rubber rings can be made of high-temperature-resistant and corrosion-resistant materials to adapt to the high temperature and corrosive raw materials that may be involved in the production process of the chlorfenapyr. Specifically, the sealing rubber rings can be fixed on the annular sealing boss 51, the annular limiting boss 42, and the sealing piston 61 by embedding or bonding, so as to ensure that the parts always maintain good sealing effect during operation of the device.

[0067] By arranging the sealing rubber rings at key positions, the sealing performance of the device is further improved, and the stability and safety of the raw material conveying process are ensured. Compared with the prior art, the device of the present application has significant advantages in sealing performance and durability, and can better meet the needs of industrial production.

[0068] Further, the present application also proposes that the sealing pipe 4 away from the sealing sleeve 5 is provided with a threaded connection pipe 41, the feeding pipe 31 and the discharge pipe 32 are both provided with a connecting port 33 for connecting the threaded connection pipe 41, the outer end of the feeding pipe 31 is provided with a first flange 311, and the outer end of the discharge pipe 32 is provided with a second flange 321.

[0069] By arranging the threaded connection pipe 41 at the end of the sealing pipe 4 away from the sealing sleeve 5, and arranging the connecting port 33 for connecting the threaded connection pipe 41 on the feeding pipe 31 and the discharge pipe 32, reliable connection of the sealing pipe 4 with the feeding pipe 31 and the discharge pipe 32 is achieved. The outer ends of the feeding pipe 31 and the discharge pipe 32 are respectively provided with the first flange 311 and the second flange 321, which further enhances the stability and sealing performance of the connection.

[0070] The threaded pipe 41 can be connected with the connecting port 33 on the feed pipe 31 and the discharge pipe 32 in a threaded manner, which has the characteristics of convenient disassembly and assembly and firm connection. The first flange 311 and the second flange 321 are arranged, so that the stability and sealing performance of the pipe connection are further improved through the flange connection, and it is ensured that the raw materials will not leak during the conveying process. Through this design, the problem of poor connection and poor sealing performance of the sealing pipe 4 with the feed pipe 31 and the discharge pipe 32 in the prior art is solved, and the reliability and safety of the automatic feeding device are improved. Therefore, the continuity and stability of the production process are ensured, and equipment failure and production accidents caused by poor connection are avoided.

[0071] The first pressure gauge 312 is arranged on the feed pipe 31, and the second pressure gauge 322 is arranged on the discharge pipe 32.

[0072] In order to improve the stability and accuracy of the raw material conveying in the production process, the first pressure gauge 312 and the second pressure gauge 322 are arranged on the feed pipe 31 and the discharge pipe 32, respectively. Through the two pressure gauges, the pressure change in the feed pipe 31 and the discharge pipe 32 can be monitored in real time, so that the working state of the pump body 3 can be adjusted in time, and it is ensured that the raw materials always remain in the appropriate pressure range during the conveying process, thereby avoiding the problem of unstable raw material conveying caused by pressure fluctuation.

[0073] For example, if the pressure displayed by the first pressure gauge 312 is too low during the production process, it may mean that the raw materials in the raw material tank 1 are insufficient or the feed pipe 31 is blocked, so the raw materials need to be supplemented or the feed pipe 31 needs to be cleaned in time. If the pressure displayed by the second pressure gauge 322 is too high, it may mean that the discharge pipe 32 is blocked or the feed port of the reaction kettle 2 is blocked, so the discharge pipe 32 or the feed port of the reaction kettle 2 needs to be cleaned in time. Therefore, by arranging the first pressure gauge 312 and the second pressure gauge 322, the automation degree of the production process can be effectively improved, manual intervention can be reduced, and the continuity and stability of the production can be ensured.

[0074] The pressure gauges arranged on the feed pipe 31 and the discharge pipe 32 can monitor the pressure change in the raw material conveying process in real time, adjust the working state of the pump body 3 in time, and ensure the stability and accuracy of the raw material conveying. Compared with the prior art, the technical scheme of the present application has the advantages of simple structure, easy implementation, and can significantly improve the automation degree and production efficiency of the production process, reduce the problem of unstable raw material conveying caused by pressure fluctuation, and improve the product quality and production safety.

[0075] Further, the application also proposes that the raw material storage tank 1 and the reaction kettle 2 are connected through the feeding pipe 31 and the discharging pipe 32, the feeding pipe 31 is connected with the feeding pipe 11 of the raw material storage tank 1, and the discharging pipe 32 is connected with the feeding pipe 21 of the reaction kettle 2. By arranging the feeding pipe 31 and the discharging pipe 32 between the raw material storage tank 1 and the reaction kettle 2, the raw material can be transported from the raw material storage tank 1 to the reaction kettle 2 through the feeding pipe 31 for reaction. The feeding pipe 31 is connected with the feeding pipe 11 of the raw material storage tank 1, so that the raw material can smoothly enter the feeding pipe 31. The discharging pipe 32 is connected with the feeding pipe 21 of the reaction kettle 2, so that the raw material can smoothly enter the reaction kettle 2 for reaction.

[0076] Further, the connection mode of the feeding pipe 31 and the discharging pipe 32 can adopt common pipeline connection modes such as threaded connection and flange connection, so as to ensure the reliability and sealing performance of the connection. For example, the feeding pipe 31 and the discharging pipe 32 can be connected through the threaded connection pipe 41, one end of the threaded connection pipe 41 is connected with the feeding pipe 31 or the discharging pipe 32, and the other end is connected with the feeding pipe 11 of the raw material storage tank 1 or the feeding pipe 21 of the reaction kettle 2.
