Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a temperature control component and an unsaturated resin reaction device. Background Technology

[0002] In the synthesis of unsaturated resins, the reactants are highly sensitive to temperature changes and need to be maintained within a specific range. Common reaction equipment uses external jackets for heating, but this method has significant delays, and the material temperature can easily exceed the set range, affecting the performance of the final product. Simultaneously, components in the reactants such as alcohols and styrene corrode sealing materials. The sealing rings installed between flanges are constantly exposed to high temperatures and corrosive environments, making them prone to deformation or detachment from the mounting groove, leading to media leakage and requiring frequent shutdowns for replacement, thus disrupting production continuity. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the sealing ring being easily deformed or loosened, by proposing a temperature control component and an unsaturated resin reaction device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A temperature control assembly includes a vessel body and a heating jacket fitted onto the outer wall of the vessel body. A heat-conducting pipe is spirally wound around the outer wall of the vessel body within the range of the heating jacket. The outer wall of the heating jacket is provided with two flanges, which are respectively connected to the two ends of the heat-conducting pipe. The flanges are connected to a hot oil pipe and a water-cooling pipe through a tee pipe. Valves are provided on both the hot oil pipe and the water-cooling pipe.

[0006] In one possible design, a temperature sensor is installed inside the vessel, and the temperature sensor is electrically connected to a PLC switching temperature control module and a PID temperature control module. The valve is electrically connected to the PLC switching temperature control module and the PID temperature control module.

[0007] An unsaturated resin reaction apparatus, including the aforementioned temperature control component, further includes:

[0008] The lid is installed on the top of the vessel body via a flange structure. A feeding port is provided on the top of the lid, and a stirrer is installed on the top of the lid.

[0009] The sealing ring has an upper groove and a lower groove respectively on the bottom of the vessel cover flange and the top of the vessel body flange. The sealing ring is embedded in the upper groove and the lower groove. The bottom of the sealing ring has an annular groove.

[0010] A fixing ring is fitted into the ring groove. Multiple sockets are fixedly provided on the top of the fixing ring. Multiple through holes communicating with the ring groove are opened on the top of the sealing ring. A slot that mates with the socket is opened on the inner wall of the top of the upper groove.

[0011] The inner ring is rotatably mounted at the bottom of the fixed ring. Multiple L-shaped clamping plates are fixedly mounted on the top of the inner ring. The top of the vertical section of the clamping plate extends into the interior of the socket, and the end of the horizontal section of the clamping plate can penetrate into the exterior of the socket. The side wall of the slot is provided with a fixing groove.

[0012] In one possible design, a torsion spring is provided between the inner ring and the fixed ring.

[0013] In one possible design, a plurality of positioning plates are fixedly provided on the top inner wall of the upper slot, the positioning plates are arranged adjacent to the slot, the through hole is sleeved on the positioning plate, and the top of the transverse section of the card plate is set as an inclined surface that cooperates with the positioning plate.

[0014] In one possible design, a plurality of positioning posts are fixedly provided on the bottom inner wall of the lower groove, and a plurality of positioning grooves that cooperate with the positioning posts are opened at the bottom of the inner ring.

[0015] In one possible design, the sealing ring is made of perfluoroelastomer rubber.

[0016] In this application, when the temperature reaches the specified temperature, the valve of the hot oil pipe is closed and the valve of the water cooling pipe is opened to achieve the effect of temperature control, avoid excess heat generated by the thermal inertia of heating and the heat of reaction generated by the material reaction, and control the temperature of the reactant material within the specified range.

[0017] When installing the sealing ring, first insert it into the upper groove and align the side wall of the through hole with the positioning plate to ensure that the slot and the through hole are aligned. Then, insert the retaining ring into the ring groove and align the top socket with the through hole before inserting it into the slot. During insertion, the inclined surface of the retaining plate will abut against the positioning plate, thereby squeezing the inner ring and causing it to rotate, thus retracting it into the socket. When the retaining ring is fully inserted, the inner ring will be reset by the force of the torsion spring, thus inserting it into the fixing groove on the side wall of the slot to fix the retaining ring and complete the installation of the sealing ring.

[0018] When the lid with the sealing ring is then placed on top of the vessel body, the bottom of the sealing ring will be inside the lower groove, and the positioning post inside the lower groove will be inserted into the corresponding positioning slot to limit the inner ring and ensure stability during normal operation.

[0019] In this utility model, the temperature control component and unsaturated resin reaction equipment can increase the control of the reaction temperature through the heat exchange structure, thereby reducing the thermal inertia problem of traditional equipment and increasing the stability of product quality.

[0020] In this utility model, the temperature control component and unsaturated resin reaction equipment can achieve a stable installation of the sealing ring through a mechanical locking mechanism, which facilitates subsequent replacement and avoids displacement and detachment.

[0021] In this invention, a snap-locking fixing mechanism is used to ensure the stability of the sealing ring installation and prevent detachment, thus making it suitable for the production environment of unsaturated resin. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In one embodiment: Reference Figure 1A temperature control component includes: a vessel body 1 and a heating jacket 5 fitted on the outer wall of the vessel body 1. A heat-conducting metal tube is spirally wound in the space between the outer wall of the vessel body 1 and the heating jacket 5. The two ends of the heat-conducting tube are respectively connected to two flange interfaces symmetrically arranged on the outer wall of the heating jacket 5.

[0030] One flange interface is connected to both the external hot oil supply pipeline and the cooling water pipeline via a tee fitting, and electrically controlled valves are installed on both pipelines respectively; the other flange interface serves as a medium return port.

[0031] A temperature sensor is installed inside the reactor body 1. The temperature sensor is connected to a PLC switch temperature control module and a PID temperature control module. The valve is electrically connected to the PLC switch temperature control module and the PID temperature control module. This module operates on the same principle as the PLC switch temperature control module and PID temperature control module in a rapid heating and temperature control system for a reactor (announcement number CN216964589U). In use, the hot oil pipeline is connected to an external oil pump and oil pipe to achieve heating. When the temperature of the reactants inside the reactor body 1 reaches the target reaction temperature, the valve of the hot oil pipeline is closed and the valve of the water cooling pipe is opened. This counteracts the excess heat generated by the thermal inertia of heating and the heat of reaction generated by the material reaction, preventing the temperature of the reactants from exceeding the control range of the target reaction temperature. Then, the PID temperature control module controls the opening of the flow valve to maintain temperature stability.

[0032] refer to Figure 2-5 The reaction equipment is based on the aforementioned temperature control component. The equipment also includes a vessel cover 2 connected to the top of the vessel body 1 via a flange. The top of the vessel cover 2 is provided with a feed port 3 and a mounting base for a stirrer 4.

[0033] A lower groove 12 is machined on the flange end face of the vessel body 1, and a corresponding upper groove 15 is machined on the flange end face of the vessel cover 2. The sealing ring 6 is fitted between the two grooves and is made of corrosion-resistant perfluoroether rubber material, with an annular groove 17 at its bottom.

[0034] The retaining ring 7 is embedded in the ring groove 17, and multiple sockets 9 are evenly distributed around its top. The top of the sealing ring 6 has a through hole 18 corresponding to the socket 9, and the inner wall of the top of the upper groove 15 is machined with a slot 13 that mates with the socket 9.

[0035] The inner ring 8 is rotatably mounted on the bottom of the fixed ring 7, and multiple L-shaped retaining plates 10 are fixed to its top. The vertical section of the retaining plate 10 extends into the socket 9, and the horizontal section can extend out from the opening in the side wall of the socket. A torsion spring is provided between the inner ring 8 and the fixed ring 7 to provide a reset torque.

[0036] The upper groove 15 is also provided with multiple positioning plates 14 on the top inner wall for guiding and positioning during installation.

[0037] Specifically, the sealing ring 6 is first placed in the upper groove 15, so that the through hole 18 is fitted onto the positioning plate 14 to achieve pre-positioning, thereby ensuring that the through hole 18 is connected to the corresponding slot 13. Then, the retaining ring 7 is inserted into the ring groove 17, so that the socket 9 passes through the through hole 18 and is inserted into the slot 13. During this process, the inclined surface of the retaining plate 10 contacts the positioning plate 14, forcing the inner ring 8 to rotate and retract the retaining plate 10. When the retaining ring 7 is fully in place, the torsion spring drives the inner ring 8 to reset, causing the transverse section of the retaining plate 10 to pop out and lock into the fixing groove on the side wall of the slot 13, completing the mechanical locking of the sealing ring. The sealing ring 6 achieves sealing through the inner and outer layers.

[0038] This application can be used in the field of chemical equipment, or in other fields applicable to this application.

[0039] In another embodiment: Reference Figure 4-5 An unsaturated resin reaction device, in order to ensure the stability of the locking, is applied in the field of chemical equipment. Multiple positioning columns 11 are fixed on the bottom inner wall of the lower groove 12 and are arranged in a ring at equal intervals. The bottom of the inner ring 8 is provided with a corresponding positioning groove 16.

[0040] When the cover is closed, the bottom of the sealing ring 6 enters the lower groove 12, and the positioning post 11 is inserted into the positioning groove 16 to achieve circumferential limiting of the inner ring 8, ensuring the stability of the sealing structure during operation. The positioning groove 16 can also be used as a slot for rotating the inner ring 8 later.

[0041] However, as is well known to those skilled in the art, the working principle and wiring method of the temperature control module are conventional methods or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0042] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
