DETAILED DESCRIPTION

[0023] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 8 The present invention provides a technical solution: a PVA screw barrel with exhaust function, comprising a feeding chamber 1, a bottom pipe of the feeding chamber 1 is connected to a chamber 2, a pipe below the chamber 2 is connected to a feeding chamber 3, a screw 4 is arranged inside the feeding chamber 3, a driving chamber 5 is fixed on the left side of the feeding chamber 3, and a driving mechanism is arranged inside the driving chamber 5, and the screw 4 is fixedly connected to the output end of the driving mechanism;

[0025] A drying chamber 6 is fixed to the right side of the feeding chamber 3, a material channel 41 is provided on the surface of the screw 4, an exhaust groove 7 is provided on one side of the feeding chamber 3, an exhaust chamber 8 is fixed on one side of the chamber 2, a pipeline is connected between the top of the exhaust groove 7 and the bottom of the exhaust chamber 8, an air outlet pipe 9 is connected to the top of the exhaust chamber 8, and a dispersing mechanism is provided inside the exhaust chamber 8, which includes a heat insulation chamber 81, a motor 82, fan teeth 83, a gear 84, a rotating rod 85 and a plurality of fan blades 86;

[0026] The granular material is put into the feeding chamber 1, and the granular material enters the chamber 2 through the pipeline, and the granular material enters the feeding chamber 3 through the pipeline. Then the driving mechanism in the driving chamber 5 drives the screw 4 to rotate, and the screw 4 conveys the granular material into the drying chamber 6 through the material channel 41 on its surface for material drying. Compared with the traditional screw 4, one end of the screw 4 can save costs and has a good material transmission effect. High-temperature water vapor is generated during the melting process of the material and is input into the exhaust chamber 8 through the exhaust groove 7. The high-temperature water vapor is initially dissipated by the scattering mechanism in the exhaust chamber 8, and then discharged to the outside through the exhaust pipe 9 to avoid the high exhaust temperature causing the working environment temperature to rise.

[0027] The heat-insulating cavity 81 is fixedly mounted on the upper left corner of the inner wall of the exhaust cavity 8, the motor 82 is fixedly mounted on the inner wall of the heat-insulating cavity 81, the fan teeth 83 are fixedly connected to the output end of the motor 82, the gear 84 is fixedly mounted on the inner wall of the exhaust cavity 8, the rotating rod 85 is fixedly mounted on one side of the gear 84, the interior of the rotating rod 85 is hollow, and a plurality of sliding holes are arranged on the surface, and a plurality of fan blade plates 86 are respectively slidably connected in the plurality of sliding holes;

[0028] The sector teeth 83 and the gear 84 mesh with each other;

[0029] After the high-temperature water vapor enters the exhaust chamber 8, the motor 82 runs to drive the fan teeth 83 to rotate, and the fan teeth 83 rotate to engage with the gear 84, thereby driving the gear 84 to rotate. The motor 82 rotates at a high speed, causing the gear 84 to rotate at a high speed. The gear 84 drives the fan blade plate 86 to rotate at a high speed through the rotating rod 85 to disperse the high-temperature water vapor, thereby allowing the high-temperature water vapor to be initially dissipated to avoid the subsequent high temperature after being discharged to the outside, resulting in an increase in the working environment temperature, and to avoid the high exhaust temperature causing burns to the staff while working.

[0030] An impact plate 87 and a track 88 are fixed to the left side of the inner wall of the exhaust chamber 8. The track 88 is located above the impact plate 87. A slider 881 is slidably connected to the inner wall of the track 88. The upper part of the slider 881 is connected to the upper part of the inner wall of the exhaust chamber 8 by a spring. An impact rod 882 is fixed to the lower part of the slider 881. The bottom end of the impact rod 882 is spherical and contacts the impact plate 87.

[0031] A plurality of tooth blocks are fixed to the right side of the slider 881, and mesh with the sector teeth 83 through the plurality of tooth blocks;

[0032] After the fan tooth 83 rotates, it first meshes with the gear 84 and then with the slider 881, driving the slider 881 to slide upward along the inner wall of the track 88. The spring is deformed under force, and the fan tooth 83 continues to rotate until it disengages from the slider 881. The spring generates a reaction force to quickly reset the slider 881. The slider 881 drives the impact rod 882 to move upward first, then quickly moves downward, and impacts the impact plate 87. The impact generates vibration, which can vibrate the high-temperature water vapor in the exhaust chamber 8 on the one hand to improve the heat dissipation effect. On the other hand, when exhausting, impurities in the high-temperature water vapor adhere to the outlet pipe 9 and the exhaust chamber 8. The vibration can clean the impurities to avoid continuous exhaust causing the outlet pipe 9 to be blocked and affecting the exhaust effect.

[0033] A telescopic joint 89 is fixed to the upper right corner of the exhaust chamber 8, the outer end of the telescopic joint 89 is spherical, the outer end of the blade plate 86 is spherical, and a sphere 861 is arranged at the inner end, a gas pressure chamber 862 is fixed to the inner wall of the exhaust chamber 8, and a gas pressure plate 863 is slidably connected to the inner wall of the gas pressure chamber 862;

[0034] A pneumatic rod 864 is fixed to the front side of the pneumatic plate 863. The front end of the pneumatic rod 864 is spherical and fits together with the sphere 861. A push-pull plate 865 is fixed to the outside of the pneumatic rod 864. The pneumatic plate 863 is connected to one side of the inner wall of the pneumatic cavity 862 by a spring.

[0035] An air cavity 883 is fixed on the left side of the inner wall of the exhaust cavity 8, and a slide plate 884 is slidably connected to the inner wall of the air cavity 883. The slide plate 884 is fixedly installed on the outer side of the impact rod 882. Holes are provided on the upper and lower sides of the air cavity 883, and the impact rod 882 is slidably connected in the holes.

[0036] The lower part of the air cavity 883 is connected to the expansion joint 89 pipeline;

[0037] During the up and down movement of the impact rod 882, the slide plate 884 is driven to slide up and down along the inner wall of the air cavity 883. When the slide plate 884 moves downward, gas is injected into the telescopic joint 89 through the pipeline, so that the telescopic joint 89 extends. At this time, the upper end of the fan blade plate 86 contacts the outer end of the telescopic joint 89, and the telescopic joint 89 squeezes it. The fan blade plate 86 is forced to slide along the inner wall of the sliding hole. The bottom end ball 861 of the fan blade plate 86 squeezes the front end ball part of the gas pressure rod 864, and the gas pressure rod 864 drives the gas pressure plate 863 to move backward along the inner wall of the gas pressure cavity 862. The spring slides and deforms under force. When the impact rod 882 moves upward, the gas in the telescopic joint 89 is extracted, and the fan blade plate 86 is out of contact with the telescopic joint 89. At this time, the pneumatic rod 864 loses its force to the rear side, and the spring generates a reaction force to make the pneumatic plate 863 quickly reset. The pneumatic rod 864 moves back and forth, thereby driving the push-pull plate 865 to move back and forth. The push-pull plate 865 moves back and forth to shake the high-temperature water vapor in the exhaust chamber 8, thereby further improving the heat dissipation efficiency and further reducing the temperature of the high-temperature water vapor when it is discharged to the outside.

[0038] The rear side of the air pressure chamber 862 is connected to the top of the air chamber 883 by a pipeline, and a pressure valve and a pressure chamber are arranged in the pipeline. The pressure chamber is located on the right side of the pressure valve. The rear side of the air pressure chamber 862 is connected to an external pipeline, and a one-way valve is arranged in the pipeline. The top of the air chamber 883 is connected to an external control valve pipeline.

[0039] When the air pressure plate 863 slides back and forth along the inner wall of the air pressure chamber 862, it continuously extracts and injects external gas into the pressure chamber. When the gas pressure in the pressure chamber reaches the pressure limit of the pressure valve, the pressure valve opens, and the gas quickly enters the air chamber 883, and pushes the slide plate 884 to move downward quickly, thereby increasing the impact force. After that, the external control valve opens, and the air pressure in the air chamber 883 returns to normal. The speed at which the impact rod 882 moves downward is accelerated, the impact force is strengthened, and the vibration intensity is increased, so that impurities can be cleaned to the greatest extent, thereby fully avoiding pipeline blockage. On the other hand, intermittent impact can reduce structural loss, and the service life is relatively guaranteed.

[0040] At the same time, the impact force increases, and the extension speed of the telescopic joint 89 increases, so that the intensity of the push-pull plate 865 shaking back and forth increases, and the heat dissipation effect is further enhanced.

[0041] The chamber 2 is provided with a temperature meter inside, and a temperature identification module is provided inside the temperature meter. The temperature identification module is electrically connected to the motor 82, and the temperature identification module is used to identify the temperature of the feed and control the speed of the motor 82 according to the temperature;

[0042] The higher the feeding temperature, the faster the speed of the motor 82, and vice versa. On the one hand, the speed of the motor 82 is accelerated in response to high temperature, thereby increasing the intensity of breaking up the high-temperature water vapor, allowing the high-temperature water vapor discharge chamber to quickly dissipate heat, avoiding the increase in the working environment temperature after discharge. On the other hand, it can relatively reduce energy consumption and save operating costs.
