[0002] A reactor is broadly defined as a container where physical or chemical reactions occur. Through structural design and parameter configuration, the required heating, evaporation, cooling, and low-speed mixing functions are achieved. A reactor heating device is required to heat the reactor.

[0003] Chinese patent document CN220091344U discloses a reactor heating pipe for epoxy resin production, comprising a first spiral pipe, a second spiral pipe, a first water inlet, a second water inlet, a first water outlet, a second water outlet, a water inlet pipe, and a water outlet pipe. The first and second spiral pipes are both embedded in the reactor shell and arranged alternately. The first water inlet at the top of the first spiral pipe and the second water inlet at the bottom of the second spiral pipe are both connected to the water inlet pipe, and the first water outlet at the bottom of the first spiral pipe and the second water outlet at the top of the second spiral pipe are both connected to the water outlet pipe. The water inlet pipe is equipped with a control valve and an impact mechanism, and the control valve is located near the impact mechanism near the reactor. Hot water enters the first spiral pipe through the first water inlet and flows from the top to the bottom of the first spiral pipe, while hot water enters the second spiral pipe through the second water inlet and flows from the bottom to the top of the second spiral pipe.

[0004] The disadvantage of the above disclosed solution is that the water flows at a relatively high speed in the first spiral tube and the second spiral tube, resulting in a relatively low utilization rate of the heat of the water. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a reactor heating device, which can slow down the flow rate of hot water by arranging convex strips on the convex surface, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a reactor heating device, comprising a spiral tube, which is embedded in the shell of the reactor, the water inlet end of the spiral tube is connected to a water distribution pipe, the water inlet end of the water distribution pipe is connected to a water inlet pipe, the water outlet end of the spiral tube is connected to a water outlet pipe, and the water outlet pipe is connected to a drain pipe, a convex surface is provided in the spiral tube, the convex surface is arranged along the extension direction of the inner wall of the spiral tube, and a plurality of convex strips are fixedly provided on the convex surface.

[0007] Furthermore, the spiral tube includes a first spiral tube and a second spiral tube, the first spiral tube and the second spiral tube are arranged alternately, and the input ends of the first spiral tube and the second spiral tube are opposite.

[0008] Furthermore, the water distribution pipe includes a first water distribution pipe and a second water distribution pipe, the first water distribution pipe is connected to the water inlet end of the first spiral pipe, and the second water distribution pipe is connected to the water inlet end of the second spiral pipe.

[0009] Furthermore, the water outlet pipe includes a first water outlet pipe and a second water outlet pipe, the first water outlet pipe is connected to the water outlet end of the first spiral pipe, and the second water outlet pipe is connected to the water outlet end of the second spiral pipe.

[0010] Furthermore, the inner tube walls of the spiral tube, the water distribution pipe and the water outlet pipe are all symmetrically provided with convex surfaces.

[0011] Furthermore, a concave surface is formed on the outer tube wall corresponding to the convex surface, and a plurality of protrusions are fixedly arranged in the concave surface.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Because the spiral tube is provided with a convex surface extending along the inner wall of the spiral tube and having multiple ridges fixed thereon, the convex surface and ridges increase the contact area between the hot water and the tube wall as the hot water flows through the tube. The ridges also slow down the flow rate of the hot water, thereby increasing the time the hot water stays in the tube and allowing the heat of the hot water to be fully dissipated into the reactor, thereby improving the utilization rate of the hot water heat.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 2The utility model provides a technical solution: a reactor heating device, including a spiral tube, the spiral tube including a first spiral tube 4 and a second spiral tube 5, the first spiral tube 4 and the second spiral tube 5 are both embedded and installed in the shell of the reactor, the first spiral tube 4 and the second spiral tube 5 are arranged alternately, and the input ends of the first spiral tube 4 and the second spiral tube 5 are opposite.

[0019] The water inlet end of the spiral tube is connected to a water distribution pipe, which includes a first water distribution pipe 2 and a second water distribution pipe 3. The first water distribution pipe 2 is connected to the water inlet end of the first spiral tube 4, and the second water distribution pipe 3 is connected to the water inlet end of the second spiral tube 5. The first water distribution pipe 2 is located below the second water distribution pipe 3, and the water inlet ends of the first and second water distribution pipes 2 and 3 are connected to the water inlet pipe 1, through which hot water is introduced into the first and second water distribution pipes 2 and 3.

[0020] The water outlet of the spiral tube is connected to an outlet pipe, which includes a first outlet pipe 6 and a second outlet pipe 7. The first outlet pipe 6 is connected to the water outlet of the first spiral tube 4, and the second outlet pipe 7 is connected to the water outlet of the second spiral tube 5. The second outlet pipe 7 is located below the first outlet pipe 6, and the outlets of the first and second outlet pipes 6 and 7 are connected to a drain pipe 8. Water is discharged through the drain pipe 8.

[0021] The first spiral tube 4, the second spiral tube 5, the first water distribution tube 2, the second water distribution tube 3, the first water outlet tube 6, and the second water outlet tube 7 are all symmetrically provided with convex surfaces 10, which are arranged along the extension direction of the inner wall of the tube. Furthermore, a plurality of ridges 11 are fixedly provided on the convex surfaces 10, and the ridges 11 are arranged at equal distances from each other.

[0022] A concave surface 9 is formed on the outer tube wall corresponding to the convex surface 10 , and a plurality of protrusions 12 are fixedly provided in the concave surface 9 , and the plurality of protrusions 12 are arranged at equal distances.

[0023] The working principle of a reactor heating device provided by the utility model is as follows:

[0024] During use, after water is heated in an external heating tank, it is pumped into the water inlet pipe 1 via a water pump. The water inlet pipe 1 supplies hot water to the first and second water branch pipes 2 and 3. The first water branch pipe 2 supplies hot water from the bottom of the first spiral pipe 4 into the first spiral pipe 4. The second water branch pipe 3 supplies hot water from the top of the second spiral pipe 5 into the second spiral pipe 5. This allows the hot water to flow in opposite directions from the top and bottom of the reactor, thereby evenly heating and maintaining the temperature of the reactor and improving the reaction effect of the substances inside.

[0025] During the flow of hot water, since the convex surfaces 10 are symmetrically arranged on the inner tube wall and the ridges 11 are fixedly arranged on the convex surfaces 10, the convex surfaces 10 and the ridges 11 increase the contact area between the hot water and the tube wall on the one hand, and at the same time, the ridges 11 are used to slow down the flow rate of the hot water, thereby increasing the time that the hot water stays in the tube and allowing the heat of the hot water to be fully dissipated into the reactor, thereby improving the utilization rate of the heat of the hot water.

[0026] At the same time, since the concave surface 9 is formed at the position of the outer tube wall corresponding to the convex surface 10, and the convex block 12 is fixedly provided on the concave surface 9, the arrangement of the concave surface 9 and the convex block 12 can increase the heat dissipation area of ​​the spiral tube, so that the heat of the hot water can be fully dissipated into the reactor, further improving the heating speed and the utilization rate of the hot water heat.

[0027] Finally, the hot water flows upward through the first spiral tube 4 to the first water outlet pipe 6, and flows downward through the second spiral tube 5 to the second water outlet pipe 7, so that the water in the first water outlet pipe 6 and the second water outlet pipe 7 is collected in the drain pipe 8 and flows back to the external heating water tank.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
