Problems solved by technology

[0003] In order to solve the above-mentioned technology, when the polypropylene powder is dried with a dryer, because a small part of the polypropylene powder is mixed together by the suction of the liquid, the weight of the whole powder is relatively large, and the force of the airflow remains unchanged. The entire group of powder falls down to the bottom of the drying chamber, causing the powder at the bottom of the drying chamber to be continuously heated and softened due to excessive temperature, which affects the normal processing and use of polypropylene powder. The invention provides a polypropylene with dryer

Embodiment 1

[0025] as attached figure 1 to attach Figure 5 Shown:

[0026] The present invention provides a drying machine for polypropylene, the structure of which comprises a machine body 1, a control box 2, a drying cylinder 3, and a hot air blower 4. Fixed above the body 1, the hot air blower 4 is installed at the right end of the body 1.

[0027] The drying cylinder 3 is provided with a drying chamber 31, a feeding pipe 32, a discharge hopper 33, and a crushing mechanism 34. The drying chamber 31 is located inside the drying cylinder 3, and the feeding pipe 32 is vertically fixed on the drying chamber. On the top of the drying cylinder 3 , the discharge hopper 33 is connected to the left end of the drying cylinder 3 , and the crushing mechanism 34 is placed at the bottom of the drying chamber 31 .

[0028] Wherein, the crushing mechanism 34 is provided with a crushing chamber a1, an opening a2, a stacking chamber a3, an air flow groove a4, a swing block a5, a push bar a6, and a p...

Embodiment 2

[0034] as attached Image 6 to attach Figure 7 Shown:

[0035] Wherein, the air flow groove a4 is provided with a limit block r1, a clamp r2, a connecting shaft r3, and a reset bar r4, the limit block r1 is connected with the inner top of the left end of the air flow groove a4, and the left end of the clamp r2 passes through The connecting shaft r3 is connected and installed on the left inner wall of the air flow groove a4, and the reset strip r4 is sandwiched between the upper surface of the left end of the clamp r2 and the left inner wall of the air flow groove a4. There are two reset strips r4, which can increase the reset The thrust of the bar r4 on the clamp r2 speeds up the reset speed of the clamp r2, which is conducive to blocking the powder through the clamp r2, reducing the powder entering the air flow groove a4, and speeding up the diffusion of the air flow along the air flow groove a4.

[0036] Wherein, the clamp r2 is provided with a plate body t1, a top groove t...

Abstract

The invention discloses a dryer for polypropylene. The dryer structurally comprises a machine body, a control box, a drying cylinder and an air heater, wherein the control box is arranged on the front face of the left side of the machine body, the drying cylinder is fixed to the upper portion of the machine body, and the air heater is installed at the right end of the machine body. Caked powder is relatively high in weight and falls off to the inner bottom of a drying cavity, a crushing mechanism is provided with a crushing cavity, a swing block and a push plate impact and disperse the caked fallen powder and then discharge the powder, the phenomenon that the powder at the bottom of the drying cavity is softened due to the fact that the powder is continuously heated and the temperature is too high can be reduced, and normal processing and using of the polypropylene powder are facilitated; and because the power in an accumulation cavity falls off into an air flow groove and blocks the air flow groove, the powder is blocked by a clamping plate, so that the powder entering the air flow groove can be reduced, the diffusion of the air flow along the air flow groove can be accelerated, and the blowing and discharging of the powder in the accumulation cavity by the air flow can be accelerated.

Description

technical field [0001] The invention belongs to the field of polypropylene, and more specifically relates to a dryer for polypropylene. Background technique [0002] The polypropylene powder is dried by a dryer, the polypropylene powder is fed from the feed pipe of the dryer to the inside of the drying cylinder, the hot air blower flows into the right side of the dryer, and the powder falls down Under the action of the hot air flow, it is discharged to the discharge hopper on the left and dried; when the polypropylene powder is dried by a dryer in the prior art, a small part of the polypropylene powder is mixed into a ball by the suction of the liquid, and the whole ball The weight of the powder is relatively large, and the force of the airflow remains unchanged, causing the whole group of powder to fall down to the bottom of the drying chamber, resulting in the phenomenon that the powder at the bottom of the drying chamber is continuously heated and the temperature is too h...
