[0004] However, the above device still has shortcomings:

[0005] When heating is in progress, the interior of the device is affected by the heat and the gas inside the device will expand faster. If heating continues and the pressure inside the device cannot be balanced in time, the device will be at risk of explosion, thus affecting the safety of the staff. Utility Model Content

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a reactor for preparing polyester resin for high-hardness powder coatings, which solves the problem that when heating, the internal part of the device is affected by the heat, causing the gas inside the device to expand rapidly. If heating continues and the pressure inside the device cannot be balanced in time, the device may explode, thereby affecting the safety of workers.

[0007] To achieve the above-mentioned object, the utility model proposes a reactor for preparing polyester resin for high-hardness powder coating, comprising a reactor barrel, wherein a power rod is rotatably connected to the interior of the reactor barrel, and a stop assembly is provided on the side wall of the power rod, wherein:

[0008] The stop assembly includes a stop bin, which is fixedly connected to the side wall of the power rod, and a pair of rotating shaft blocks are fixedly connected to the inner wall of the top of the stop bin, and a rotating disc is rotatably connected to the inside of the pair of rotating shaft blocks, and a blocking plate is fixedly connected to the side wall of the rotating disc, and an electronic trigger alarm is fixedly connected to the end of the blocking plate away from the rotating shaft block, and a slide is fixedly connected to the side wall of the rotating disc, and a pair of annular grooves are provided on the inner wall of the bottom of the stop bin, and the end of the slide away from the rotating shaft block is slidably connected to the inside of the annular groove, and balancing holes are provided on both side walls of the stop bin.

[0009] Preferably, the top of the reactor barrel is fixedly connected to a top cover, the top of the top cover is fixedly connected to a motor, and the top of the power rod is fixedly connected to the motor.

[0010] Preferably, a heat flow channel is provided inside the power rod, a plurality of stirring rods are fixedly connected to the bottom side wall of the power rod, a plurality of one-way valve holes are provided on the surface of the stirring rod, a heating channel is provided on the side wall of the reactor barrel, a heater is fixedly connected to the outer side wall of the reactor barrel, an annular pipe is provided on the top of the top cover, the heating channel is connected to the annular pipe, a fixed disk is fixedly connected to the top side wall of the power rod, the fixed disk is rotatably connected to the top of the top cover, a rotating disk is rotatably connected to the outer side of the fixed disk, the rotating disk is connected to the annular pipe, and the rotating disk is fixedly connected to the inside of the top cover.

[0011] Preferably, a pressure plug is connected through the top of the reactor barrel.

[0012] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure of described sliding panel also is provided with an interlocking structure.

[0013] Preferably, an annular frame is provided on the outside of the reactor barrel, and the annular frame is fixedly connected to the side wall of the bracket.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Through the setting of the cut-off component, when the device is heated, as the temperature rises, the volume of the gas in the reactor barrel will gradually expand. Since the reactor barrel is a closed structure, as the gas expands, the gas will enter the cut-off chamber through the balance hole. Driven by the gas, the slide will be pushed to rotate with the rotating disk as the center until a pair of barrier plates contact and block the heat flow channel. At this time, heat will not be able to enter the device. In addition, a pair of electronic trigger alarms will send an electrical signal after contacting, and the control device will sound an alarm to remind the staff that there is a problem with the device and it needs to be repaired.

[0016] The benefit of this design is that when the temperature is too high, the air pressure in the reactor barrel will increase rapidly. Blocking the heat flow channel prevents heat from entering, ensuring the safety of operators and equipment. Secondly, certain polyester resin reactions require a specific temperature range. Excessively high temperatures may cause side reactions or degradation of the reactants, thereby affecting product quality. Promptly blocking the heat flow channel can prevent the adverse effects of excessive temperatures on product quality and ensure that the product meets the expected requirements.

[0017] 2. The noise reduction component can be set to achieve this. When the device is working, the spring will be compressed under the influence of the gravity of the reactor barrel. At this time, the small hole will slide upward in the sliding groove, and the small hole will pull the piston to slide outward. The inside of the empty warehouse will produce a negative pressure effect, and the air hole will be tightly adsorbed on the square warehouse, thereby achieving a fixed effect. When the device shakes up and down, the spring can act as a buffer, and the cross bar can slide on the square warehouse but cannot detach.

[0018] The advantage of this design is that the noise can be reduced by fixing and buffering the surface reactor barrel without it falling off the noise reduction component. In addition, the firmness of the fixation depends on the gravity of the device itself. The greater the gravity, the more secure the fixation. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. 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.

[0026] like Figure 1-5 As shown, a reactor for preparing polyester resin for high-hardness powder coating comprises a reactor barrel 1, the interior of which is rotatably connected to a power rod 4, and a side wall of the power rod 4 is provided with a stop assembly 5.

[0027] The stopping assembly 5 includes a stopping bin 51, which is fixedly connected to the side wall of the power rod 4. A pair of rotating shaft blocks 52 are fixedly connected to the inner wall of the top of the stopping bin 51. The inside of the pair of rotating shaft blocks 52 are both rotatably connected to a rotating disc 53. The side wall of the rotating disc 53 is fixedly connected to a blocking plate 54. The end of the blocking plate 54 away from the rotating shaft block 52 is fixedly connected to an electronic trigger alarm 55. The side wall of the rotating disc 53 is fixedly connected to a slide plate 56. A pair of annular grooves 57 are provided on the inner wall of the bottom of the stopping bin 51. The end of the slide plate 56 away from the rotating shaft block 52 is slidably connected to the inside of the annular groove 57. Balance holes 58 are provided on both side walls of the stopping bin 51.

[0028] When the device is heated, as the temperature rises, the volume of the gas in the reactor barrel 1 will gradually expand. Since the reactor barrel 1 is a closed structure, as the gas expands, the gas will enter the stop chamber 51 through the balance hole 58. Driven by the gas, the slide 56 will be pushed to rotate with the rotating disk 53 as the center until a pair of baffles 54 contact to block the heat flow channel 41. At this time, heat will not be able to enter the device. In addition, a pair of electronic trigger alarms 55 will send an electrical signal after contact, and the control device will send an alarm to remind the staff that there is a problem with the device and it needs to be repaired.

[0029] The advantage of this design is that when the temperature is too high, the air pressure in the reactor tank 1 will increase rapidly. Blocking the heat flow channel 41 can prevent heat from entering, ensuring the safety of operators and equipment. Secondly, some polyester resin reactions require a specific temperature range. Excessively high temperatures may cause side reactions or degradation of the reactants, thereby affecting product quality. Promptly blocking the heat flow channel 41 can prevent the adverse effects of excessive temperatures on product quality, ensuring that the product meets the expected requirements.

[0030] The top of the reactor barrel 1 is fixedly connected to a top cover 2 , the top of the top cover 2 is fixedly connected to a motor 3 , and the top of the power rod 4 is fixedly connected to the motor 3 .

[0031] A heat flow channel 41 is provided inside the power rod 4, and a plurality of stirring rods 42 are fixedly connected to the bottom side wall of the power rod 4. A plurality of one-way valve holes 43 are provided on the surface of the stirring rod 42. A heating channel 45 is provided on the side wall of the reactor barrel 1, and a heater 44 is fixedly connected to the outer side wall of the reactor barrel 1. An annular pipe 451 is provided on the top of the top cover 2, and the heating channel 45 is connected to the annular pipe 451. A fixed disk 47 is fixedly connected to the top side wall of the power rod 4, and the fixed disk 47 is rotatably connected to the top of the top cover 2. A rotating disk 48 is rotatably connected to the outer side of the fixed disk 47, and the rotating disk 48 is connected to the annular pipe 451. The rotating disk 48 is fixedly connected to the inside of the top cover 2, and an air pressure plug 46 is connected through the top of the reactor barrel 1.

[0032] A noise reduction component 6 is provided on the outside of the reactor barrel 1. The noise reduction component 6 includes a bracket 61. The bottom of the bracket 61 is rotatably connected to a roller 62. The top of the bracket 61 is fixedly connected to a cross bar 63. The side wall of the reactor barrel 1 is fixedly connected to a square bin 64. The cross bar 63 extends away from one end of the bracket 61 into the square bin 64. A sliding groove 65 is provided on one side of the square bin 64 close to the bracket 61. The square bin 64 is slidably connected in the sliding groove 65. The cross bar 63 extends to an empty bin 68 at one end of the square bin 64. The cross bar 63 extends to the square bin 64. An air hole 612 is provided at one end of the warehouse 64, and the air hole 612 is connected to the empty warehouse 68. A small hole 610 is provided inside the cross bar 63, and the small hole 610 is connected to the empty warehouse 68. A connecting rope 611 is provided inside the small hole 610. A piston 69 is slidably connected to the interior of the empty warehouse 68, and a ring 66 is fixedly connected to the interior of the sliding groove 65. The two ends of the small hole 610 are respectively fixedly connected to the piston 69 and the sliding groove 65. A spring 67 is provided inside the square warehouse 64, and the two ends of the spring 67 are respectively fixedly connected to the square warehouse 64 and the cross bar 63.

[0033] When the device is working, affected by the gravity of the reactor barrel 1, the spring 67 will be compressed. At this time, the small hole 610 will slide upward in the sliding groove 65. The small hole 610 pulls the piston 69 to slide outward, and a negative pressure effect is generated inside the empty chamber 68. The air hole 612 will be tightly adsorbed on the square chamber 64, thereby achieving a fixing effect. When the device shakes up and down, the spring 67 can act as a buffer, and the cross bar 63 can slide on the square chamber 64 but cannot detach.

[0034] The advantage of this design is that the noise can be reduced by fixing and buffering the surface reactor barrel 1 without it falling off the noise reduction component 6. In addition, the firmness of the fixation depends on the gravity of the device itself. The greater the gravity, the more secure the fixation.

[0035] An annular frame 613 is provided on the outside of the reactor barrel 1 , and the annular frame 613 is fixedly connected to the side wall of the bracket 61 .

[0036] Working principle: When the device is heated, as the temperature rises, the volume of the gas in the reactor barrel 1 will gradually expand. Since the reactor barrel 1 is a closed structure, as the gas expands, the gas will enter the stop chamber 51 through the balance hole 58. Driven by the gas, the slide 56 will be pushed to rotate with the rotating disk 53 as the center until a pair of blocking plates 54 contact to block the heat flow channel 41. At this time, heat will not be able to enter the device. In addition, a pair of electronic trigger alarms 55 will send an electrical signal after contact, and the control device will send an alarm to remind the staff that there is a problem with the device and it needs to be repaired.

[0037] When the device is working, affected by the gravity of the reactor barrel 1, the spring 67 will be compressed. At this time, the small hole 610 will slide upward in the sliding groove 65. The small hole 610 pulls the piston 69 to slide outward, and a negative pressure effect is generated inside the empty chamber 68. The air hole 612 will be tightly adsorbed on the square chamber 64, thereby achieving a fixing effect. When the device shakes up and down, the spring 67 can act as a buffer, and the cross bar 63 can slide on the square chamber 64 but cannot detach.
