Description

Technical Field

[0001] The invention relates to the technical field of chemical equipment, in particular to a single flange port material sampling and reflux equipment on a kettle top. Background Art

[0002] Reactors are widely used in the core operations of material reaction, mixing and storage in the fields of chemical, pharmaceutical, and food. In order to ensure product quality and process stability, real-time sampling and analysis of material composition in the reactor is a key link. However, the sampling process often faces challenges, involving the diversity of materials, maintenance of sampling purity, system cleaning, and reflux management. Traditional material sampling and reflux equipment have certain limitations when facing these problems, and it is difficult to meet the needs of efficient, accurate, and pollution-free sampling in the production process.

[0003] The materials in the reactor may have different fluidity, from low-viscosity liquids to high-viscosity viscous materials. Traditional equipment lacks the ability to flexibly handle these materials and can only use a single sampling method. This leads to residual materials in the pipeline after sampling, especially for materials with high viscosity that are difficult to empty naturally, further increasing the difficulty of cleaning and maintenance.

[0004] Therefore, in view of the above problems, the present invention proposes a material sampling and reflux device with a single flange port on the top of a kettle. Summary of the invention

[0007] Preferably, the material taking component comprises a connecting through-tube, one end of which is connected to a through hole at the bottom of the transition box, and the other end of which is detachably connected to a material taking valve.

[0008] Preferably, the outer wall of the connecting through pipe is connected to a liquid separation hose, and the middle part of the liquid separation hose is connected to an electric valve.

[0009] Preferably, the plurality of driving assemblies all include an air pump, each of the air pumps is installed on the outer wall of the transition box, each of the air pump output ends is connected to one end of an air duct, the other end of the air duct is connected to a connector, and the other end of the connector is connected to the top of the transition box.

[0010] Preferably, a plurality of the drive assemblies are arranged equidistantly around the outside of the transition box.

[0011] Preferably, a spring 1 is connected to the upper surface of the through-hole piston and the inner wall of the transition box, and a spring set is arranged outside the connecting pipe.

[0012] Preferably, the heating component comprises a protective sleeve, the protective sleeve is sleeved on the outside of the curved portion, an electric heating tape is wound around the outer wall of the curved portion, and the outside of the electric heating tape is arranged inside the protective sleeve.

[0013] Preferably, the reset assembly component includes a connecting disk, the middle part of which is installed on the outer wall of the introduction tube, and a plurality of guide columns are slidably arranged in the middle part of the connecting disk, and the bottoms of the plurality of guide columns are installed on the top of the connecting flange, and a spring 2 is sleeved on the outside of each of the guide columns, and the upper and lower ends of the spring 2 are respectively connected to the connecting disk and the outer wall of the connecting flange.

[0014] Preferably, a plurality of the guide posts are arranged equidistantly around the outside of the introduction tube.

[0015] Preferably, an extension tube is threadedly connected to the bottom of the introduction tube.

[0016] Working principle: When using the equipment, first connect the connecting flange to the single flange port on the top of the sampling kettle, and then connect the liquid separation hose to the connecting port on the outer wall of the kettle body. After the preparation work is completed, start the material taking valve to sample the material. During sampling, the material flows into the middle of the transition box through the introduction pipe, the bend, the connecting pipe and the middle hole of the through-hole piston, and then enters the material taking bottle under the extraction action of the material taking valve. After the material taking is completed, close the material taking valve. At this time, the material flow area between the introduction pipe, the bend, the connecting pipe, the transition box and the connecting through pipe forms a closed space, and the internal space contains the material absorbed during the material taking process. For liquid materials with high fluidity, it is only necessary to start the electric valve at this time to change The pressure between the variable inlet pipe, the bend, the connecting pipe, the transition box and the connecting through pipe is automatically refluxed or the liquid separation hose is returned to the inside of the kettle body. For materials with low fluidity, the air pump and the electric heating tape need to be started at this time. The electric heating tape will heat the adhered material inside the bend to increase its fluidity. At the same time, the transition box heats the material inside it. Then the air pump generates powered air, which quickly fills the upper part of the through-hole piston and the space area formed by the transition box and its inner wall through the air guide pipe and the connector. Driven by the pressure, the through-hole piston moves downward inside the transition box, thereby changing the pressure difference between the inlet pipe, the bend, the connecting pipe and the transition box. The change in pressure difference causes the residual The material is squeezed and refluxed by the compressed air and flows back to the kettle body. At this time, the residual material in the inlet pipe, the bend and the connecting pipe ends the reflux, and then the electric valve is opened to contact the sealing state of the internal space of the inlet pipe, the bend, the connecting pipe and the transition box. The sticky material remaining in the transition box and the connecting through-tube will return to the kettle body through the liquid separation hose. Then the compressed air in the upper part of the through-hole piston and the space formed by the transition box and its inner wall is reduced, and the spring 1 and spring 2 rebound, driving the inlet pipe, the bend and the connecting pipe to reset, and the residual material inside the equipment is cleared; in order to ensure that the equipment can be put into the sampling work of different materials and does not affect the subsequent chemical or physical analysis of the materials, it can be Insert the extension tube at the bottom of the inlet pipe into the barrel filled with clean water, remove the material extraction valve, and then connect the extraction equipment to the end of the connecting pipe to allow clean water to enter the equipment, flush the inlet pipe, the bend, the connecting pipe, the transition box, the connecting pipe and the inner wall of the liquid separation hose, and use the above-mentioned working process for the reflux of sticky materials to operate. In this process, the electric valve is not opened first, and the pressure difference is used to make the clean water flush back and forth in the inlet pipe, the bend and the connecting pipe for many times, so that the inner wall of the inlet pipe, the bend and the connecting pipe is fully cleaned, and then the electric valve is opened again, and the clean water flows out from the inside of the liquid separation hose through multiple times, so as to achieve the purpose of fully cleaning the inner wall of the liquid separation hose.

[0017] The present invention provides a single flange port material sampling and reflux device on the top of a kettle, which has the following beneficial effects: 1. The present invention adopts differentiated treatment methods for materials with different fluidity, so that the materials can be fully refluxed. For materials with high fluidity, the pressure difference is changed by simply adjusting the electric valve to achieve automatic reflux to the kettle body; for viscous or poor fluidity materials, electric heating is combined to increase fluidity, and compressed air is used to promote the reflux of residual materials, ensuring that the residual materials in the pipeline can be completely emptied, reducing material waste and improving sampling accuracy.

[0018] 2. The entire system of the present invention remains airtight during the sampling, emptying and cleaning processes to prevent the material from contacting the outside world, ensure the purity of the sample and the safety of the operating environment, and reduce the risk of leakage of harmful materials. In addition, the closed reflux reduces the waste of materials, so that the residual materials after sampling can fully flow back to the kettle body, thereby improving the production cost-effectiveness.

[0019] 3. The present invention flexibly adjusts the pressure difference through compressed air and valve control system, and clean water repeatedly flushes the inner wall of the pipeline and the hose. Through multiple cleanings, the entire interior of the equipment can be cleaned without dead corners, ensuring rapid conversion of different material sampling, reducing downtime, and avoiding cross-contamination of materials.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Please see attached Figure 1 -Attached Figure 2 The embodiment of the present invention provides a single-flange material sampling and reflux device for a kettle top, comprising a connecting flange 1 for connecting the kettle top, an inlet pipe 2 slidingly arranged in the middle of the connecting flange 1, a curved portion 3 connected to the top of the inlet pipe 2, the curved portion 3 connected to one end of a connecting pipe 5 through a one-way valve 4, a through-hole piston 6 arranged at the other end of the connecting pipe 5, a transition box 7 slidingly arranged on the outer wall of the through-hole piston 6, a cavity in the middle of the connecting pipe 5 being communicated with the through-hole in the middle of the through-hole piston 6, a material taking component connected to the bottom of the transition box 7, a plurality of driving components arranged on the transition box 7, which are used to push the through-hole piston 6 to move downward on the inner wall of the transition box 7, when the electric valve 20 is closed, a pressure difference is formed inside the transition box 7, and liquid reflux is pushed, a heating component is arranged on the outer wall of the curved portion 3, which is used to make materials with higher viscosity obtain greater fluidity, a resetting component is arranged on the outer wall of the inlet pipe 2, which is used to assist in resetting the overall flow pipeline, and further assist in moving the through-hole piston 6 upward and resetting on the inner wall of the transition box 7.

[0024] Specifically, when using the equipment, first connect the connecting flange 1 to the single flange port on the top of the sampling kettle, and then connect the liquid separation hose 9 to the connecting port on the outer wall of the kettle body. After the preparation work is completed, start the material sampling valve 10 to perform material sampling. During sampling, the material flows into the middle of the transition box 7 through the inlet pipe 2, the curved part 3, the connecting pipe 5 and the middle hole of the through-hole piston 6, and then enters the material taking bottle under the extraction action of the material taking valve 10. After the material taking is completed, close the material taking valve 10. At this time, the material flow area between the inlet pipe 2, the curved part 3, the connecting pipe 5, the transition box 7 and the connecting through pipe 8 forms a closed space, and the internal space contains the material absorbed during the material taking process. For liquid materials with high fluidity, it is only necessary to start the electric valve at this time. Door 20 changes the pressure between the inlet pipe 2, the bend 3, the connecting pipe 5, the transition box 7 and the connecting through pipe 8, and the residual liquid automatically refluxes or the liquid separation hose 9 returns to the inside of the kettle body. For materials with high viscosity, it is necessary to heat the internal materials through the heating component and the transition box 7. Due to the combination of the bend 3, the inlet pipe 2 and the connecting pipe 5, the heights of the ports at both ends of the overall pipeline are inconsistent. The horizontal position of the port connected to the transition box 7 is higher than the port entering the inside of the kettle body, so as to form a height difference later. The fluidity of the heated viscous material increases, which is convenient for its flow at the bend 3. Then the drive component is started to generate a pressure difference, so that the material flows back into the kettle body. At the same time, the pressure difference can be used to complete the cleaning of the inside of the equipment.

[0025] Please see attached Figure 1 The material taking component includes a connecting pipe 8, one end of which is connected to the through hole at the bottom of the transition box 7, and the other end of the connecting pipe 8 is detachably connected to a material taking valve 10.

[0026] Please see attached Figure 1 -Attached Figure 2The outer wall of the connecting pipe 8 is connected to a liquid separation hose 9, and the middle of the liquid separation hose 9 is connected to an electric valve 20.

[0027] Specifically, for liquid materials with high fluidity, it is only necessary to start the electric valve 20 to change the pressure between the inlet pipe 2, the bend 3, the connecting pipe 5, the transition box 7 and the connecting pipe 8, and the residual liquid will automatically flow back or the liquid separation hose 9 will return to the inside of the kettle body, so that the equipment can perform targeted reflux operations for materials of different viscosities, thereby maximizing the return of residual materials inside the equipment to the kettle body.

[0028] Please see attached Figure 3 -Attached Figure 5 , multiple driving components all include an air pump 11, each air pump 11 is installed on the outer wall of the transition box 7, the output end of each air pump 11 is connected to one end of an air guide pipe 12, the other end of the air guide pipe 12 is connected to a connector 13, and the other end of the connector 13 is connected to the top of the transition box 7.

[0029] A plurality of drive components are arranged around the outside of the transition box 7 at equal distances.

[0030] Specifically, for materials with low fluidity, it is necessary to start the air pump 11 and the electric heating belt 18. The electric heating belt 18 will heat the adhesive material inside the bend 3 to increase its fluidity. At the same time, the transition box 7 will heat the material inside it. Then the air pump 11 generates dynamic air, which quickly fills the upper part of the through-hole piston 6 and the space area formed by the transition box 7 and its inner wall through the air guide pipe 12 and the connector 13. Under the pressure, the through-hole piston 6 moves down inside the transition box 7, thereby changing the pressure difference between the introduction pipe 2, the bend 3, the connecting pipe 5 and the transition box 7. The change in pressure difference causes the residual material to be squeezed and refluxed under the push of compressed air and flow back to the kettle body. At this time, the reflux of the residual material in the introduction pipe 2, the bend 3 and the connecting pipe 5 ends. At the same time, the pressure effect can be used to make the clean water flush back and forth inside the pipeline for multiple times, so that the inner wall of the pipeline can be fully cleaned.

[0031] Please see attached Figure 3 A spring 14 is connected to the upper surface of the through-hole piston 6 and the inner wall of the transition box 7 , and the spring 14 is sleeved on the outside of the connecting pipe 5 .

[0032] The reset assembly includes a connecting plate 15, the middle part of which is installed on the outer wall of the introduction tube 2, and a plurality of guide columns 16 are slidably arranged in the middle part of the connecting plate 15, and the bottoms of the plurality of guide columns 16 are installed on the top of the connecting flange 1, and a spring 17 is sleeved on the outside of each guide column 16, and the upper and lower ends of the spring 17 are respectively connected to the connecting plate 15 and the outer wall of the connecting flange 1.

[0033] A plurality of guide posts 16 are arranged around the outside of the introduction tube 2 at equal distances.

[0034] Specifically, when the equipment is in use, the through-hole piston 6 moves downward, causing the connecting pipe 5, the inlet pipe 2 and the bend 3 to move downward as a whole, thereby driving the connecting plate 15 to squeeze the spring 2 17, compressing it and generating a rebound reaction force. At the same time, the through-hole piston 6 moves downward, causing the spring 14 to stretch and generate a rebound reaction force. After the material reflux inside the equipment is completed, the compressed air in the upper part of the through-hole piston 6 and the space area formed by the transition box 7 and its inner wall is reduced. At this time, the spring 2 17 and the spring 14 generate a rebound reaction force, thereby driving the inlet pipe 2, the bend 3 and the connecting pipe 5 to reset, and the through-hole piston 6 to reset on the inner wall of the transition box 7.

[0035] Please see attached Figure 3 The heating component includes a protective sleeve 19 , which is sleeved on the outside of the curved portion 3 , an electric heating tape 18 is wound around the outer wall of the curved portion 3 , and the outside of the electric heating tape 18 is arranged inside the protective sleeve 19 .

[0036] Specifically, through the winding design of the electric heating tape 18, the material inside the curved portion 3 can be heated evenly, thereby increasing the fluidity of the material with high viscosity.

[0037] Please see attached Figure 1 The bottom of the introduction pipe 2 is threadedly connected with an extension pipe 21.

[0038] Specifically, the design of the extension pipe 21 can make the device adapt to the use of materials at different heights in the kettle.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
