Description

Technical Field

[0001] This utility model relates to the field of resin pretreatment technology, and more specifically, to a pretreatment reactor for C5 petroleum resin. Background Technology

[0002] C5 petroleum resin, also known as C5 oil resin, has become an important tackifying resin. It is widely used in hot melt adhesives, pressure-sensitive adhesives, and rubber tires. Petroleum resin is suitable for hot melt adhesives, pressure-sensitive adhesives, and rubber tires, and it has good compatibility with styrene polymers such as SIS, SBS, SEBS, and SEPS, as well as natural rubber, synthetic rubber, and EVA. The production of C5 petroleum resin requires multiple washing processes of the raw materials. For example, patent CN218250150U discloses a C5 petroleum resin pretreatment reactor, including a reactor with a feed inlet and a feed valve for controlling the opening and closing of the inlet. A control panel is fixedly installed on the reactor, equipped with a clean water switch for controlling the entry of clean water, an alkali switch for controlling the entry of alkali solution, and an ammonia switch for controlling the entry of ammonia solution. The reactor also includes a stirring device for stirring the resin particles.

[0003] When the above-mentioned device is in operation, it directly washes C5 petroleum resin with water, alkali, and ammonia through the control console, which facilitates the industrial production of C5 petroleum resin, reduces the consumption of labor, and greatly improves the work efficiency of workers. However, the rotary nozzle is prone to shaking during different stirring processes, which can cause the sealing of the rotary nozzle connection to fail, reducing its efficiency in washing materials. At the same time, during non-washing stirring processes, fine particles can cause the rotary nozzle to become clogged, making the rotary nozzle unable to work. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pretreatment reactor for C5 petroleum resin. The technical problem to be solved by the present invention is: how to increase the uniformity of material washing inside the reactor while avoiding nozzle blockage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a C5 petroleum resin pretreatment reactor, comprising a reactor body, a sealing cover at the upper end of the reactor body, a main feed pipe, multiple auxiliary feed pipes and multiple small servo motors correspondingly provided on the outer side of the upper end of the sealing cover, a water inlet pipe provided on the upper side of the outer end face of the reactor body, and a support connecting rod provided inside the reactor body;

[0006] One end of the support connecting rod is provided with a limiting sealing plate, the outer side of the limiting sealing plate is provided with a limiting ring, the inside of the limiting ring is provided with a water guiding connecting pipe, the upper side of the outer end face of the water guiding connecting pipe is provided with a connecting hose, and the outer end face of the water guiding connecting pipe is provided with a strip-shaped nozzle.

[0010] A stirring motor is provided in the middle of the upper end of the sealing cover, and the output shaft of the stirring motor passes through the end face of the sealing cover and extends into the interior of the reactor body.

[0011] In a preferred embodiment, the output shaft of the stirring motor is provided with a rotating rod inside the reactor body, the outer end face of the rotating rod is provided with a plurality of connecting rods, and the outer end face of the connecting rod is provided with a stirring plate.

[0012] In a preferred embodiment, the output shaft of the small servo motor passes through the end face of the sealing cover and extends to the lower side of the sealing cover, and the output shaft of the small servo motor is provided with an adjusting connecting rod on the lower side of the sealing cover.

[0013] In a preferred embodiment, the lower end of the adjusting connecting rod is provided with a first mounting plate and a connecting rod, and the upper end of the water guiding connecting pipe is provided with a second mounting plate, the end face of which is provided with a plurality of limiting holes.

[0014] In a preferred embodiment, the small servo motor is electrically connected to an external control device, and the water inlet pipe extends through the end face of the reactor body and is connected to a connecting hose inside the reactor body.

[0015] In a preferred embodiment, the limiting sealing plate is curved on one side in the top view, and the end face of the limiting sealing plate in the top view is adapted to the outer end face of the water guiding connecting pipe, and the inner end face of the limiting ring is adapted to the outer end face of the water guiding connecting pipe.

[0016] In a preferred embodiment, both the electromagnetic control valve and the stirring motor are electrically connected to an external control device, and the outer end face of the connecting rod is adapted to the inner end face of the limiting socket.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] In actual use, this utility model can seal the strip nozzle by setting the limiting sealing plate, the strip nozzle and the water guide connecting pipe in the corresponding state. When mixing materials, it can effectively prevent materials from entering the interior of the water guide connecting pipe from the strip nozzle, prevent materials from clogging the strip nozzle, and ensure that the strip nozzle can spray the rinsing liquid evenly.

[0019] Simultaneously, with the small servo motor, adjusting connecting rod, first mounting plate, connecting rod, limit socket, and second mounting plate in their corresponding configurations, the adjusting connecting rod and water guide connecting pipe can be driven by an external control device to swing left and right at a specific angle. This allows the strip nozzle to evenly rinse the internal raw materials of the reactor body, improving the efficiency and effectiveness of rinsing the internal materials of the reactor body. After rinsing the materials, some impurities may remain on the inner wall of the reactor body. By controlling the rotation angle of the small servo motor, the strip nozzle can be made to swing towards the inner wall of the reactor body, thus facilitating the rinsing of the inner wall of the reactor body.

[0028] The upper side of the outer end face of the reactor body 1 is provided with a water inlet pipe 10, which can be connected to an external water supply device to facilitate the flushing of the inside of the reactor body 1. The inside of the reactor body 1 is provided with a support connecting rod 17.

A support foot 2 is provided on the outer side of the lower end of the reactor body 1, and an observation window 3 is provided in the middle of the outer end face of the reactor body 1.

[0030] A stirring motor 6 is provided in the middle of the upper end of the sealing cover 4.
