Description

Technical Field

[0001] The invention relates to the technical field of hydrocarbon resin production, and in particular to a reaction kettle for producing hydrocarbon resin raw materials. Background Art

[0002] Hydrocarbon resins are a type of synthetic resins with carbon and hydrogen as the main components. They are usually manufactured through petrochemical processes and are lightweight thermoplastic resins. They have good thermal stability, chemical stability and good adhesion, so they are widely used in many industries and application fields. Hydrocarbon resins often need to be mixed with a variety of solvents, plasticizers, fillers, etc. during the production process.

[0003] At present, commonly used reactors all have a simple stirring component inside. During the mixing process of hydrocarbon resin, the viscosity of hydrocarbon resin will change, especially after adding plasticizers and fillers. Too high viscosity will increase the difficulty of mixing, resulting in uneven stirring and even damage to the equipment. In the document (application number: CN202122361303.4), a high-viscosity resin stirred reactor is disclosed, which is characterized by: comprising a kettle body, a stirring device and a power device, the discharge port of the kettle body is arranged at the bottom, the stirring device is arranged in the kettle body, the power device is connected to the stirring device, and drives the stirring device to rotate, the stirring device comprises a main shaft, a vertical stirring device and a dispersing device, the main shaft can be rotatably extended into the kettle body, the vertical stirring device is installed on the main shaft and rotates synchronously with the main shaft, the dispersing device is arranged around the vertical stirring device, and a plurality of dispersing devices are arranged at intervals along the vertical stirring device. The device achieves high-viscosity stirring by setting up multiple stirring devices and dispersing devices. First, when no plasticizer and filler are added to the hydrocarbon resin, the viscosity is relatively small. Using this device is likely to cause excessive stirring, causing air to be stirred into the resin to form bubbles. At the same time, during the high-viscosity stirring process, bubbles are more likely to form, seriously affecting the quality of the hydrocarbon resin. Summary of the invention

DETAILED DESCRIPTION

[0030] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] Embodiment 1, as Figure 1-Figure 9 As shown, a reactor for producing hydrocarbon resin raw materials comprises a reactor 1, a temperature control device is arranged on the outside of the reactor 1, a top cover 3 is fixedly installed on the top of the reactor 1, a separating funnel 4 is arranged on the top of the top cover 3, a stirring shaft 5 is rotatably installed inside the reactor 1, an inner sleeve 6 is sleeved on the outer side of the stirring shaft 5, an outer sleeve 7 is sleeved on the outer side of the inner sleeve 6, the inner sleeve 6 can be locked on the stirring shaft 5 and the top cover 3, the outer sleeve 7 is locked on the inner sleeve 6 and the top cover 3, the bottom end of the inner sleeve 6 is provided with an outer conical gear 61, and the bottom end of the outer sleeve 7 is provided with an inner conical gear 71;

[0032] A plurality of mounting branch pipes 53 are arranged on the outer side of the bottom end of the stirring shaft 5, and a mounting shaft 8 is rotatably mounted on the outer side of the mounting branch pipe 53, and an outer bevel gear 84 is fixedly mounted on one end of the mounting shaft 8 close to the stirring shaft 5, and the outer bevel gear 84 is meshed with the outer bevel gear teeth 61, and a stirring blade 1 9 is fixedly mounted on the outer side of the mounting shaft 8, and a stirring blade 2 10 is rotatably mounted on the outer side of the mounting shaft 8, and an inner bevel gear 101 is fixedly mounted on one end of the stirring blade 2 10 close to the stirring shaft 5, and a top sleeve 102 is arranged on the other end, and the inner bevel gear 101 is meshed with the inner bevel gear teeth 71;

[0033] The interiors of the stirring shaft 5 and the mounting shaft 8 are both hollow in design. An inner spray hole 82 is formed through the outer side of the mounting shaft 8 , and an outer spray hole 103 is formed through the outer side of the top sleeve 102 .

[0034] When mixing, first add the raw materials into the reactor 1. At this time, the inner sleeve 6 is locked on the stirring shaft 5, and the outer sleeve 7 is locked on the inner sleeve 6. Then start the equipment, the stirring shaft 5 rotates, and the stirring shaft 5 drives the stirring blades 1 9 and the stirring blades 2 10 to rotate. At this time, the stirring blades 1 9 and the stirring blades 2 10 are both in an inclined state, which can better complete the stirring of the raw materials. After stirring for a period of time, add the plasticizer, and at the same time unlock the inner sleeve 6 from the stirring shaft 5 and lock it on the top cover 3, and unlock the outer sleeve 7 from the inner sleeve 6. When the stirring shaft 5 rotates again, the stirring shaft 5 drives the mounting shaft 8 to rotate relative to the inner sleeve 6, and the mounting shaft 8 drives the outer bevel gear 84 to rotate around the outer bevel gear teeth 61. The outer bevel gear teeth 61 drive the outer bevel gear 84 to rotate relative to the stirring shaft 5, and the outer bevel gear 84 drives the mounting shaft 8 and the stirring shaft 5. The blade 1 9 rotates relative to the stirring shaft 5. At this time, since the outer sleeve 7 is not restricted, the outer sleeve 7 cannot provide the inner bevel gear 101 with a rotational driving force. The stirring blade 2 10 does not generate a stirring force under the action of the viscosity of the raw material. Therefore, only the stirring blade 1 9 rotates in the vertical direction to generate a shear force to mix the viscous raw materials evenly. As the viscosity of the raw materials increases, bubbles are easily generated inside during stirring. Therefore, a liquid defoamer is simultaneously introduced into the stirring shaft 5. The liquid defoamer enters the mounting shaft 8 through the mounting branch pipe 53. Since the mounting shaft 8 rotates relative to the stirring blade 2 10, when the inner spray hole 82 rotates to correspond to the outer spray hole 103, the defoamer is sprayed out. By means of pulse spraying, the stirring blade 1 9 shears the raw material in the vertical direction, so that the defoamer can be evenly mixed into the raw material, effectively suppressing the generation of bubbles.

[0035] When the filler is added, the viscosity of the raw material will further increase. At this time, the outer sleeve 7 is also locked on the top cover 3. When the stirring shaft 5 rotates again, the stirring shaft 5 drives the installation shaft 8 to rotate relative to the inner sleeve 6 and the outer sleeve 7. The installation shaft 8 drives the outer bevel gear 84 to rotate around the outer bevel gear 61. The outer bevel gear 61 drives the outer bevel gear 84 to rotate relative to the stirring shaft 5. The outer bevel gear 84 drives the installation shaft 8 and the stirring blade 1 9 to rotate relative to the stirring shaft 5. At the same time, the inner bevel gear 101 rotates around the inner bevel gear teeth 71. The inner bevel gear teeth 71 drive the inner bevel gear 101 to rotate. The inner bevel gear 101 drives the stirring blade 2 10 relative to The stirring shaft 5 rotates. It should be noted that the transmission ratio of the outer conical gear 61 and the outer bevel gear 84 is 5:1, and the transmission ratio of the inner conical gear 71 and the inner bevel gear 101 is 15:1. Therefore, the rotation speed of the stirring blade 10 is three times that of the stirring blade 1 9. The stirring blade 10 will rotate relative to the stirring blade 1 9 and the mounting shaft 8. When the inner spray hole 82 rotates to correspond to the outer spray hole 103, the defoaming agent is sprayed, and the pulse spraying frequency increases, further ensuring that the defoaming agent is added evenly. Moreover, by rotating the stirring blade 1 9 and the stirring blade 2 10 at the same time and rotating at a differential speed, the raw materials with higher viscosity can be better mixed, and the mixing effect is good.

[0036] Therefore, the use of the reactor of the present invention to produce hydrocarbon resin can ensure that it can be fully mixed and uniform at all times, and no bubbles will be generated, which can greatly improve the production quality. The present invention can better control the pressure and flow rate through the setting of the separatory funnel 4;

[0037] It should be noted that the present invention can increase the number of outer sleeves 7 and stirring blades 10 according to usage needs to achieve more varied stirring effects.

[0039] By screwing the locking screw 63 into the locking nut 62, and pressing the locking nut 62 onto the stirring shaft 5, while keeping the locking nut 62 away from the locking plate 35, the inner sleeve 6 can be locked onto the stirring shaft 5, and the outer sleeve 7 can be locked onto the inner sleeve 6 in the same way;

[0040] When the locking screw 63 is screwed into the locking nut 1 36 and is located in the locking nut 2 62, the inner sleeve 6 is locked on the top cover 3. Similarly, the outer sleeve 7 can be locked on the top cover 3. When the locking screw 63 is screwed into the locking nut 1 36 and is away from the locking nut 2 62, the outer sleeve 7 is not restricted and cannot provide driving force to the inner bevel gear 101. The control structure is simple.

Since the radius of the driven wheel 51 is smaller than the radius of the driving wheel 34, the effect of labor-saving transmission can be achieved, the torque force of the stirring motor 33 can be amplified, and the raw materials with higher viscosity can be stirred more stably.
