Description

Technical Field

[0001] The utility model relates to the technical field of reaction heating, in particular to a reaction heating device. Background Art

[0002] Reactors are widely used in petroleum, pesticides, dyes, medicines, and foods as pressure vessels to complete processes such as vulcanization, polymerization, and condensation. During the reaction, the substances inside the reactor need to be heated or cooled.

[0003] Most of the heaters inside the existing reaction devices are fixed in one position and can only dissipate heat at one position, so that the heat dissipated by the heater needs to be slowly transmitted to other positions in the reactor, resulting in poor heating effect.

[0004] In view of this, Chinese patent CN219209897U discloses an internal heater of a polystyrene reactor, which drives a rotating rod to rotate through a motor, so that a fixed sleeve on the rotating rod drives an annular cover plate to rotate through a connecting frame, and the annular cover plate drives two heaters to rotate in the heat transfer oil, so that the heater can quickly and evenly heat the heat transfer oil. The heat transfer oil surrounds the reactor, thereby transferring the temperature of the heat transfer oil to the polystyrene in the heating tank, which can quickly heat the polystyrene in the reactor and greatly improve the efficiency of polystyrene processing.

[0005] By comparing the above existing documents, the inventor believes that the following defects still exist:

[0006] The comparative document changes the position of the heater by rotating the heater, so that the heat transfer oil is heated more evenly, thereby improving the heating effect of the reactor. However, in actual use, the rotation of the heater during use is prone to problems such as unstable power supply voltage and poor circuit contact. These problems may affect the normal use of the heater and are not recommended for promotion. In view of this, we propose a reaction heating device to solve the above problems. Utility Model Content

[0027] See also Figure 1 and Figure 2 , comprising a shell 1 and a heating chamber 2 fixedly mounted on the inner wall of the shell 1 , a feed pipe 23 extending to the outside of the shell 1 being fixedly mounted on the top of the heating chamber 2 .

[0028] The outer wall of the shell 1 is provided with a heat transfer oil adding assembly, and the outer wall of the heating chamber 2 is installed with a plurality of electric heating plates 3 for heating the heat transfer oil.

[0030] The present application heats the heat transfer oil by means of a plurality of electric heating plates 3 , and then utilizes the fluidity of the heat transfer oil to make the heating chamber 2 more evenly heated, thereby improving the heating effect of the heating chamber 2 .

[0031] See also Figure 3 , Figure 4 and Figure 5 A stirring assembly for stirring the heating oil is arranged inside the shell 1, and the stirring assembly includes a first rotating cover 4 rotatably mounted on the inner top wall of the shell 1, and a plurality of first stirring rods 12 are fixedly mounted on the surface of the first rotating cover 4, a second rotating cover 9 is rotatably mounted on the top of the heating bin 2, and a plurality of second stirring rods 11 are fixedly mounted on the surface of the second rotating cover 9, and a first conical gear ring 10 is also fixedly mounted on the surface of the second rotating cover 9, a rotating rod 8 is rotatably mounted on one side of the feed pipe 23, and a first conical gear 7 meshing with the first conical gear ring 10 is fixedly mounted on the side of the rotating rod 8 away from the feed pipe 23, and a second conical gear ring 6 meshing with the first conical gear 7 is also fixedly mounted on the surface of the first rotating cover 4.

[0032] In this embodiment, the heat transfer oil adding assembly includes an oil inlet pipe 20 fixedly mounted on the surface of the shell 1, and an oil outlet pipe 19 is also fixedly mounted on the surface of the shell 1.

[0033] The oil inlet pipe 20 is used to add heat transfer oil between the shell 1 and the heating chamber 2, and the oil outlet pipe 19 is used to discharge the heat transfer oil.

[0034] In addition, in the present application, the oil outlet pipe 19 and the oil inlet pipe 20 can also be used to add coolant, and then cooperate with the first stirring rod 12 and the second stirring rod 11 to drive the flow of coolant, thereby improving the cooling efficiency of the device after heating is completed.

[0035] See also Figure 5 In this embodiment, a driving assembly for driving the first rotating cover 4 to rotate is also provided on the top of the shell 1, and the driving assembly includes a motor 14 fixedly mounted on the surface of the shell 1, and a rotating shaft 15 extending into the interior of the shell 1 is fixedly mounted on the output end of the motor 14, and a first gear 16 is fixedly mounted on the end of the rotating shaft 15 away from the motor 14, and a first gear ring 5 meshing with the first gear 16 is also fixedly mounted on the surface of the first rotating cover 4.

[0036] Among them, the starting motor 14 drives the first gear 16 to rotate, thereby rotating the first rotating cover 4 through the first gear ring 5. When the first rotating cover 4 rotates, it will drive the second conical gear ring 6 to rotate, thereby rotating the first conical gear 7, and then rotating the second rotating cover 9 through the first conical gear ring 10. Therefore, the heat transfer oil can be stirred by the first stirring rod 12 and the second stirring rod 11, and the first stirring rod 12 and the second stirring rod 11 rotate in opposite directions, thereby making the heat transfer oil heat up faster, and then making the heating chamber 2 heat up faster, which greatly improves the practicality of the device.

[0037] In this embodiment, the first rotating cover 4 and the second rotating cover 9 are both located outside the feed pipe 23, and the feed pipe 23 is integrated with the shell 1 and the heating chamber 2.

[0042] See also Figure 2 In this embodiment, a liquid level sensor for detecting the liquid level of the thermal oil is fixedly mounted on the inner top wall of the shell 1 , and a controller 21 is fixedly mounted on the surface of the shell 1 .

[0043] Among them, the liquid level sensor is set to facilitate the detection of the liquid level of the heat transfer oil, thereby facilitating the staff to appropriately add or reduce the amount of heat transfer oil.

[0044] In addition, the liquid level sensor and the motor 14 are electrically connected to the controller 21 via wires, which is convenient for the operator to operate. A display is also installed on the surface of the controller 21 to display the liquid level of the heat transfer oil.

[0045] The model of the controller 21 may be STC-1000 or the like, and no further limitation is given here.

[0046] When the present embodiment is in use, the materials required for the reaction are placed into the interior of the heating bin 2 through the feed pipe 23, and then heat transfer oil of a suitable depth is placed between the shell 1 and the heating bin 2 through the oil inlet pipe 20, and the electric heating plate 3 is started to heat the heat transfer oil. The fluidity of the heat transfer oil is used to make the heating bin 2 more evenly heated, and at the same time, the motor 14 is started to drive the first gear 16 to rotate, thereby rotating the first rotating cover 4 through the first gear ring 5. When the first rotating cover 4 rotates, it will drive the second conical gear ring 6 to rotate, thereby rotating the first conical gear 7, and then rotating the second rotating cover 9 through the first conical gear ring 10, thereby stirring the heat transfer oil through the first stirring rod 12 and the second stirring rod 11, and the first stirring rod 12 and the second stirring rod 11 rotate in opposite directions, thereby making the heat transfer oil heat up faster, and thus making the heating bin 2 heat up faster, greatly improving the practicality of the device.
