Description

Technical Field

[0001] This application relates to the field of horizontal reactor technology, and more particularly to an external disc semi-tube horizontal reactor. Background Technology

[0002] An external coil reactor is a device in which heating or cooling pipes are placed outside the reactor body. It features rapid heating, high temperature resistance, corrosion resistance, hygiene, and environmental friendliness. However, current technology uses it in the production of laminated glass, bonding the PVB film between two glass panes under high temperature and pressure. With the increase in glass size and thickness, the problems of uneven heat distribution and low heat dissipation efficiency inside the high-pressure reactor are becoming increasingly prominent.

[0003] The published patent document CN221907067U discloses an external coil reactor, relating to the field of external coil reactor technology. This external coil reactor includes a reactor body. A variable frequency motor is fixedly mounted on the upper surface of the reactor body near the rear end. A stirring device is mounted on the variable frequency motor. A C-shaped fixing plate is fixedly mounted in the middle of the upper surface of the reactor body. The stirring device includes a first bevel gear, which is fixedly sleeved on the outer surface of the output end of the variable frequency motor. A second bevel gear is disposed on the top of the outer surface of the first bevel gear. The reverse rotation of the second and third bevel gears in the stirring device causes the stirring direction of multiple stirring rods to be opposite to that of multiple identical stirring rods, thereby better dispersing the raw materials in the inner wall of the outer coil reactor body, allowing the raw materials to react better, and thus improving the reaction efficiency of the outer coil reactor body. In conjunction with the above application, and compared with horizontal reactors, the outer coil is usually designed with a spiral winding, and the pitch is fixed at twice the pipe diameter. Although a medium space is reserved, the spiral structure may cause differences in heat exchange intensity at different positions around the reactor body, especially in the gap area of ​​the coil winding, where the heat transfer efficiency is low. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides an external disc semi-tube horizontal reactor, which overcomes the shortcomings of the prior art and aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: a horizontal reactor with an outer disc semi-tube, comprising a reactor body, two support plates mounted on the bottom outer side of the reactor body, a stirring assembly disposed inside the reactor body, a heat-conducting assembly disposed inside the reactor body, the heat-conducting assembly comprising an annular mounting groove formed on one side of the inner wall of the reactor body, an annular heat-conducting plate mounted at the opening of the annular mounting groove, a plurality of heat-insulating layers linearly arrayed between the annular heat-conducting plate and the inner wall of the annular mounting groove, a spiral outer disc semi-tube mounted on the outer side of the reactor body, and a heat dissipation assembly connected to the annular mounting groove at one end of the reactor body.

[0006] By adopting the above technical solution, the spiral outer half-pipe and the inner wall annular heat conduction structure, together with the heat dissipation components, can quickly adjust the material temperature and reduce local temperature differences. The insulation layer reduces heat loss, concentrates heat utilization, and reduces energy consumption. The support plate provides stable support, and the stirring components are designed with heat conduction to ensure uniform material reaction and stable equipment operation.

[0007] As a preferred technical solution of this application, there are gaps between multiple insulation layers, and multiple guide slots are formed on one side of the insulation layer in a circumferential array.

[0008] By adopting the above technical solution, the gaps between the insulation layers form an air gap, which, together with the insulation layers themselves, further reduces heat transfer loss and improves the overall insulation effect. The guide slots of the circumferential array allow the heat or cooling medium in the annular mounting slot to flow more evenly along the slot, avoiding local heat accumulation.

[0009] As a preferred technical solution of this application, the heat dissipation component includes a temperature-controlled fan disposed at one end of the reactor body, and a heat dissipation pipe is disposed between the temperature-controlled fan and the reactor body.

[0010] By adopting the above technical solution, after the temperature-controlled fan starts, it draws heat from the annular mounting groove through the heat dissipation pipe and quickly discharges it to the outside, avoiding excessive temperature. The directional airflow of the pipe and the active heat dissipation of the fan improve heat dissipation efficiency. Combined with the heat insulation layer, it achieves dynamic temperature balance and ensures stable reaction.

[0011] As a preferred technical solution of this application, one end of the heat dissipation pipe passes through one side of the reactor body and is connected to the annular mounting groove.

[0012] By adopting the above technical solution, the heat dissipation pipes are directly connected to the annular mounting slot, which facilitates the precise extraction of excess heat from the slot and prevents heat from lingering in the slot. At the same time, the temperature-controlled fan can quickly lower the internal temperature.

[0013] As a preferred technical solution of this application, a lifting ring is installed on the top outer side of the reactor body, and a discharge pipe is provided at one end of the reactor body.

[0014] By adopting the above technical solution, the lifting ring is used for lifting operations, and the discharge pipe facilitates the discharge of materials after the reaction is completed, making it easy to collect.

[0015] As a preferred technical solution of this application, the two ends of the spiral outer disk half tube are respectively provided with a liquid inlet and a liquid outlet, and both the liquid inlet and the liquid outlet are equipped with flange connecting plates. The spiral outer disk half tube is fixed to the outer wall of the reactor body by welding.

[0016] By adopting the above technical solution, the inlet and outlet realize the circulation of heating and cooling media, providing a continuous supply of media for temperature control. The spiral outer half-pipe completes heat exchange, while the flange connection makes the pipeline connection tighter, avoids media leakage, and facilitates disassembly and maintenance, adapting to different pipeline connection requirements.

[0017] As a preferred technical solution of this application, the stirring assembly includes a rotating rod rotatably fitted inside the reactor body, and the rotating rod is equipped with helical blades.

[0018] By adopting the above technical solution, the rotating rod drives the spiral blades to rotate, which can push and mix the materials in the reactor from the bottom up, avoid material sedimentation, and achieve uniform contact throughout.

[0019] As a preferred technical solution of this application, a motor is provided at one end of the reaction vessel body, and one end of the rotating rod is mounted on the output end of the motor.

[0020] By adopting the above technical solutions, the stirring intensity and speed are kept stable.

[0021] The beneficial effects of this application are: 1. The annular heat-conducting plate directly contacts the material inside the vessel, and together with the external heat transfer of the spiral outer half-tube, a dual heat-conducting structure with internal conduction and external auxiliary is formed, which makes the heat transfer path short and efficient. The insulation layer in the annular mounting groove is linearly arrayed to avoid local heat concentration, so that the temperature in each area of ​​the vessel tends to be uniform, reducing the problem of uneven material reaction and improving the stability of the material.

[0022] 2. The temperature-controlled fan is directly connected to the annular mounting slot through a heat dissipation pipe, which can selectively dissipate excess heat in the slot. Combined with the medium regulation of the spiral outer half-pipe, it forms a dual regulation of active heat dissipation and medium temperature control. It can quickly respond to temperature fluctuations during the reaction process, making its heat dissipation path direct and concentrated, avoiding heat accumulation inside the vessel, effectively protecting the equipment and reaction materials, and reducing the risk of high-temperature runaway.

Detailed Implementation

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] Reference Figure 1-6 A horizontal reactor with an outer disc semi-tube design includes a reactor body 100. Two support plates 101 are installed on the bottom outer side of the reactor body 100. A stirring assembly is installed inside the reactor body 100. A heat-conducting assembly is installed inside the reactor body 100. The heat-conducting assembly includes an annular mounting groove 200 formed on one side of the inner wall of the reactor body 100. An annular heat-conducting plate 201 is installed at the opening of the annular mounting groove 200. Multiple heat-insulating sheets 202 are linearly arranged between the annular heat-conducting plate 201 and the inner wall of the annular mounting groove 200. A spiral outer disc semi-tube 204 is installed on the outer side of the reactor body 100. A heat dissipation assembly connected to the annular mounting groove 200 is provided at one end of the reactor body 100.

[0027] The spiral outer half-tube 204 increases the contact area with the heat source or cold source, making the heat conduction path shorter and more uniform, and the heating or cooling speed is faster. The annular mounting groove 200, together with the heat insulation layer 202, reduces the heat loss inside the vessel and avoids local temperature fluctuations, resulting in higher temperature control accuracy. The heat dissipation component is directly connected to the annular mounting groove 200, which can quickly dissipate excess heat and prevent the reaction from exothermicly causing temperature runaway.

[0028] Reference Figure 1 Furthermore, there are gaps between multiple insulation layers 202, and multiple guide slots 203 are arranged in a circumferential array on one side of each insulation layer 202.

[0029] The air gaps formed by the insulation layer 202, combined with the insulation properties of the insulation layer 202 itself, further reduce the heat exchange between the reactor body 100 and the outside world, reduce heat loss, and achieve better energy saving. At the same time, the guide channel 203 allows a small amount of heat transfer medium to flow along the channel, forming local convection in the annular mounting channel 200, and precisely regulating the temperature of specific areas.

[0030] Reference Figure 1 The heat dissipation component includes a temperature-controlled fan 300 disposed at one end of the reactor body 100. A heat dissipation pipe 301 is disposed between the temperature-controlled fan 300 and the reactor body 100. One end of the heat dissipation pipe 301 passes through one side of the reactor body 100 and is connected to the annular mounting groove 200.

[0031] By cooperating with the temperature-controlled fan 300 and the heat dissipation pipe 301, the fan speed can be automatically adjusted according to the temperature inside the reactor body 100. In conjunction with the heat dissipation pipe 301, the heat inside the annular mounting groove 200 is directionally discharged, avoiding excessive or insufficient cooling, thereby achieving dynamic temperature control.

[0032] Reference Figure 1 The outer top of the reactor body 100 is equipped with a lifting ring 102, and a discharge pipe 103 is provided at one end of the reactor body 100.

[0033] The installation, relocation, or maintenance of the reactor can be completed quickly using the lifting ring 102. The discharge pipe 103 at one end of the reactor body 100, combined with the tilt angle of the horizontal reactor or the assistance of the stirring components, allows the material to flow out naturally, reducing residue inside the reactor.

[0034] Reference Figure 1 The spiral outer half-tube 204 is provided with an inlet 205 and an outlet 206 at both ends. Both the inlet 205 and the outlet 206 are equipped with flange connecting plates. The spiral outer half-tube 204 is fixed to the outer wall of the reactor body 100 by welding.

[0035] The inlet 205 and outlet 206 allow the heat transfer medium to flow smoothly in one direction within the spiral outer half-tube 204, preventing stagnation and ensuring uniform heat transfer.

[0036] Reference Figure 1 The stirring assembly includes a rotating rod 401 rotatably fitted inside the reactor body 100. The rotating rod 401 is equipped with a spiral blade 402. A motor 400 is provided at one end of the reactor body 100, and one end of the rotating rod 401 is installed on the output end of the motor 400.

[0037] The output of motor 400 drives the rotating rod 401 to rotate, causing the spiral blade 402 to rotate with the rotating rod 401, thereby generating an axial pushing force, which causes the material in the horizontal reactor to gradually flip from one end to the other, avoiding local accumulation.

[0038] Working principle: Heating or cooling medium is introduced through the inlet 205 of the spiral outer half-pipe 204. The medium flows along the spiral path and exchanges heat with the outer wall of the reactor body 100 to regulate the temperature of the material inside the reactor. At the same time, the heat insulation layer 202 in the annular mounting groove 200 reduces heat loss and optimizes the heat transfer path of the guide groove 203. The annular heat-conducting plate 201 ensures that the heat is evenly distributed inside the reactor body 100. Meanwhile, after the motor 400 starts, it drives the rotating rod 401 to rotate, which drives the spiral blades 402 to rotate, and performs spiral stirring of the material inside the reactor, so that the material is fully mixed and in contact, ensuring that the reaction proceeds evenly and efficiently. When the temperature inside the reactor body 100 exceeds the standard, the temperature control fan 300 starts and connects to the annular mounting groove 200 through the heat dissipation pipe 301 to quickly discharge the heat accumulated in the groove, achieving precise temperature control, thereby realizing and improving the uniform distribution of heat and heat dissipation efficiency. After the reaction is completed, the motor 400 and the medium supply are turned off, and the discharge pipe 103 is opened to discharge the material.
