Description

Technical Field

[0001] This utility model relates to the field of reactor piping technology, specifically to a feed pipe structure for a resin reactor. Background Technology

[0002] In resin production, the feed pipe of the reactor is a crucial component for conveying raw materials into the reactor. Resin synthesis often involves flammable, volatile, or corrosive chemicals, making the safety, controllability, and visibility of the feeding process particularly important. Traditional feed pipes often use a structure where metal pipes are directly connected to valves. While this provides a certain level of mechanical strength and sealing performance, it makes it impossible to observe the flow of materials within the pipe in real time. This makes it difficult for operators to visually determine whether the feeding is smooth, whether there are blockages, or whether the flow is interrupted, posing potential risks to process control and safe production.

[0003] Furthermore, static electricity is easily generated and accumulated during raw material transportation, especially when non-conductive materials flow. Currently, the components of the feed pipe are typically not effectively equipotentially connected, allowing static electricity to accumulate between parts and create potential differences, thus increasing the risk of discharge and threatening production safety. If ordinary transparent tubes are used for observation purposes, while improving visibility, their lack of conductivity fails to effectively dissipate static electricity, also posing a safety hazard. Utility Model Content

[0004] In order to solve the technical problems existing in the background art, this utility model provides a feed pipe structure for a resin reactor, which realizes material monitoring through observation components and effectively discharges static electricity by means of conductive metal mesh cylinder and overall conductive design.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A feed pipe structure for a resin reactor, comprising:

[0007] The first connecting pipe is connected at its lower end to the resin reactor.

[0008] The first valve is located at the upper end of the first connecting pipe;

[0009] The observation component is located at the upper end of the first valve;

[0010] The second connecting tube is located at the upper end of the observation component;

[0011] The second valve is located at the upper end of the second connecting pipe.

[0012] Furthermore, the observation components include:

[0013] The first flange is connected to the second connecting pipe;

[0014] The second flange is connected to the first valve;

[0015] A transparent tube is positioned between the first flange and the second flange.

[0016] Furthermore, the observation component also includes:

[0017] The screw is inserted between the first flange and the second flange;

[0018] The nut is screwed onto the threaded rod and secures the first and second flanges together.

[0019] Furthermore, the observation component also includes:

[0020] A metal mesh cylinder is connected between the first flange and the second flange and is fitted around the outer periphery of the transparent tube.

[0021] Furthermore, the metal mesh cylinder is electrically connected to the first flange and the second flange.

[0022] Furthermore, the first connecting pipe, the first valve, the observation component, the second connecting pipe, and the second valve are electrically connected by wires.

[0023] Furthermore, a funnel is provided at the upper end of the second valve.

[0024] Furthermore, the metal mesh cylinder is made of stainless steel woven mesh.

[0025] The beneficial effects of this utility model are:

[0026] (1) The transparent tube design allows operators to directly observe the material flow status, thereby avoiding overflow, flow interruption or feeding errors caused by blind feeding, and improving the control accuracy and reliability of the production process.

[0027] (2) The transparent tube is fastened to the first flange and the second flange by means of screws and nuts, which makes the installation and disassembly of the transparent tube easy and facilitates cleaning or replacement of the transparent tube.

[0028] (3) A metal mesh tube is installed outside the transparent tube. The metal mesh tube is electrically connected to the first flange and the second flange. This can effectively conduct away the static electricity generated when the material flows, prevent the accumulation of static electricity from causing danger, and is especially suitable for the production of flammable and explosive materials such as resin.

[0029] (4) The metal mesh tube can also provide mechanical protection for the transparent tube without hindering visual observation, thereby enhancing its durability and balancing the protection function and observation needs. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, a feed pipe structure for a resin reactor includes a first connecting pipe 1, the lower end of which is connected to the resin reactor. A first valve 2 is located at the upper end of the first connecting pipe 1. An observation component 3 is located at the upper end of the first valve 2. A second connecting pipe 4 is located at the upper end of the observation component 3. A second valve 5 is located at the upper end of the second connecting pipe 4. A funnel 6 is located at the upper end of the second valve 5. Material enters through the funnel 6. The second valve 5 controls the material in the funnel 6 to enter the second connecting pipe 4. The first valve 2 controls the material in the second connecting pipe 4 to enter the first connecting pipe 1. The material in the first connecting pipe 1 eventually enters the resin reactor. In actual production, the first valve 2 and the second valve 5 operate alternately, i.e., one is open while the other is closed, to control the material feed. The observation component 3 is used to observe the material condition inside the second connecting pipe 4. The first connecting pipe 1, the first valve 2, the observation component 3, the second connecting pipe 4, and the second valve 5 are electrically connected by wires. This ensures an effective equipotential connection between the components of the feed pipe, preventing static electricity from accumulating between parts and creating a potential difference, thus eliminating the risk of discharge and ensuring production safety.

[0039] like Figure 2 , 3As shown, the specific structure of the observation component 3 includes a first flange 31, which is connected to a second connecting pipe 4. A second flange 33 is connected to a first valve 2. A transparent pipe 32 is positioned between the first flange 31 and the second flange 33. The upper and lower ends of the transparent pipe 32 are respectively sealed to the first flange 31 and the second flange 33. The design of the transparent pipe 32 allows operators to directly observe the material flow within the second connecting pipe 4, thereby avoiding overflow, flow interruption, or feeding errors caused by blind feeding, and improving the control accuracy and reliability of the production process.

[0040] The observation assembly 3 also includes a screw 35, which passes between the first flange 31 and the second flange 33. A nut 36 is screwed onto the screw 35, securing the first flange 31 and the second flange 33 together. The screws 35 are evenly distributed around the outer circumference of the transparent tube 32. The transparent tube 32 is securely connected to the first flange 31 and the second flange 33 via the screws 35 and the nuts 36, making the installation and disassembly of the transparent tube 32 simple and facilitating cleaning or replacement.

[0041] The observation assembly 3 also includes a metal mesh cylinder 34, which is made of stainless steel woven mesh. The metal mesh cylinder 34 is connected between the first flange 31 and the second flange 33 and is fitted around the outer periphery of the transparent tube 32. The screw 35 is located inside the metal mesh cylinder 34. The metal mesh cylinder 34 is electrically connected to the first flange 31 and the second flange 33. The placement of the metal mesh cylinder 34 outside the transparent tube 32, maintaining an electrical connection with the first flange 31 and the second flange 33, effectively conducts away static electricity generated during material flow, preventing static accumulation and potential hazards. This is particularly suitable for production environments involving flammable and explosive materials such as resins. Furthermore, the metal mesh cylinder 34 provides mechanical protection for the transparent tube 32 without obstructing visual observation, enhancing its durability and balancing protective functions with observation requirements.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
