Problems solved by technology

[0003] Hydrogenated petroleum resin is a petroleum resin with better performance obtained after hydrogenation reaction of petroleum resin, which has stronger viscosity than ordinary petroleum resin. At present, the granulation of this product still chooses the rotary belt type condensation used by ordinary petroleum resin. Due to the high viscosity of the granulator, the hydrogenated petroleum resin is firmly adhered to the stainless steel belt at the end of the conventional rotary belt granulator in the molten state of 200 ° C. The resin on the steel belt, most of the granulated resin is broken, which greatly reduces the quality of the product

specific Embodiment 1

[0026] Such as figure 1 As shown, a hydrogenated petroleum resin granulator includes a distributor 1, a conveying device, a cooling device, and a discharge bin 18. The distributor 1 is arranged at the feeding end of the conveying device, the discharging bin 18 is arranged at the discharging end of the conveying device, and the lower part of the discharging bin 18 is provided with a trough 17 . The distributor 1, conveying device, cooling device, and discharge bin 18 are all arranged in the sealed casing 20, the bottom of the sealed casing 20 is connected to the equipment support 16, and the sealed casing 20 is provided with a plurality of air outlets, and the air outlets are connected to the draft hood 22 , the air-inducing hood 22 is connected to the exhaust gas treatment system.

[0027] Described conveying device comprises precooling conveying steel belt 3 and cooling conveying steel belt 19, and precooling conveying steel belt 3 blanks to cooling conveying steel belt 19, ...

specific Embodiment 2

[0034] This embodiment is basically similar to the specific embodiment 1, the difference is that

[0035] When working, measure the cooling temperature of each segment of the water spray pipeline as,

[0036]The inlet temperature of the pre-cooling inlet pipe is 50°C, the initial temperature of the material is 200°C, and the temperature is lowered to 150°C; the high-temperature cooling section: the inlet temperature of the high-temperature cooling inlet pipe is 40°C, the initial temperature of the material is 150°C, and the temperature is lowered to 100°C ℃; normal temperature cooling section: the inlet temperature of the normal temperature cooling inlet pipe is 32℃, the initial temperature of the material is 100℃, and the temperature is lowered to 60℃; the low temperature cooling section: the inlet temperature of the low temperature cooling inlet pipe is 10℃, the initial temperature of the material 60°C, cool down to 25°C.

[0037] This embodiment is the best embodiment.

Abstract

The invention relates to the field of petrochemical industry, in particular to a hydrogenated petroleum resin granulator and a granulation method thereof, comprising a distributor, a conveying device, a cooling device, and a discharge bin. The cooling device includes a water spray pipe, a water spray pipe There is a water spray port on the top, and the water spray pipe is arranged at the lower part of the conveying device. The water spray pipe includes a pre-cooling section and a graded cooling section arranged in sequence. The pre-cooling section is close to the feeding end of the conveying device. stage or multi-stage cooling sections, the cooling sections of the pre-cooling section and the graded cooling section are respectively connected to the water inlet pipes, and the water inlet pipes are connected to the cooling water, and the cooling water in the water inlet pipes of the cooling sections of the pre-cooling section and the graded cooling section The water temperature decreases successively. The invention keeps the temperature difference between the material and the cooling medium stable, and prevents the material from becoming brittle during rapid cooling and difficult to separate from the bonded steel belt.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a hydrogenated petroleum resin granulator. Background technique [0002] Hydrogenated petroleum resin has good viscosity, compatibility, thermal stability and light stability, and can improve the bonding performance of adhesives. It is an essential tackifying component of many adhesives. Widely used in hot melt, pressure sensitive adhesive, structure and decoration of construction industry, automobile assembly, tires, commodity packaging, book binding, sanitary products, shoemaking, hot-melt road marking paint, colored asphalt and other industries. [0003] Hydrogenated petroleum resin is a kind of petroleum resin with better performance after hydrogenation reaction of petroleum resin, which has stronger viscosity than ordinary petroleum resin. At present, the granulation of this product still chooses the rotary belt condensation method used by ordinary petroleum resin. Due...
