Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment, and in particular to a nitrogen protection device for bottle flakes. Background Technology

[0002] Currently, the chemical industry often involves recycled materials. Twin-screw plastic granulators are used to reprocess raw materials such as plastic waste and scrap to produce high-quality plastic granules. However, oxidation and yellowing are very likely to occur during the raw material recycling process, which affects product quality.

[0003] Currently, existing twin-screw plastic granulators connect the feed hopper directly to the flake hopper discharge pipe. When the flakes enter the feed hopper, they carry with them a certain amount of oxygen. This oxygen increases the probability of the product oxidizing and turning yellow. To solve the above problems, we propose a nitrogen protection device for flakes. Utility Model Content

[0004] The purpose of this invention is to provide a nitrogen protection device for bottle flakes, which solves the problem of existing protection devices that can reduce the air content in materials and have good stability.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a bottle flake nitrogen protection device, comprising a double-walled corrugated pipe, wherein a connecting cylinder and a distribution pipe are respectively bolted to the top and inside of the double-walled corrugated pipe, a vent hole is provided on the surface of the connecting cylinder, an air blowing port is provided on the surface of the distribution pipe, a nitrogen inlet pipe communicating with the distribution pipe is provided through the surface of the double-walled corrugated pipe, a valve is installed on the surface of the nitrogen inlet pipe, a fixing plate is fixedly sleeved at the top and bottom of the surface of the double-walled corrugated pipe, two fixing frames are provided on the surface of the double-walled corrugated pipe, two moving blocks are provided inside the fixing frames, a connecting rod is installed between one side of the moving block and the fixing plate, and a fixing spring is bolted between the other side of the moving block and the fixing frame through a spring fixing plate.

[0006] By adopting the above technical solution, the air content in the material can be reduced, the possibility and probability of product oxidation and yellowing can be reduced, the product quality can be improved, and the stability effect can be achieved. The damage caused by vibration and impact to the equipment can be reduced, the service life of the equipment can be extended, and the practicality is high.

[0007] The present invention is further configured such that a first flange and a second flange are respectively fixedly sleeved on the top end of the surface of the connecting cylinder and the bottom end of the surface of the double-walled corrugated pipe.

[0008] By adopting the above technical solution, the first flange and the second flange make it easy for personnel to fix the device between the bottle flake hopper discharge pipe and the feed hopper with screws.

[0009] The present invention is further configured such that a nitrogen flow meter is installed on the surface of the nitrogen inlet pipe.

[0010] By adopting the above technical solution and setting up a nitrogen flow meter, it is easy for personnel to observe the flow of nitrogen in the nitrogen inlet pipe.

[0011] The present invention is further configured such that a damper is installed between the other side of the movable block and the fixed frame.

[0012] By adopting the above technical solution, the damper can be used to suppress the jumping of the fixed spring and consume the kinetic energy stored in the fixed spring, thereby reducing the resonance amplitude and improving stability.

[0013] The present invention is further configured such that: a guide rod is installed on the front of the movable block, a sliding groove is provided on the front of the fixed frame, and the other end of the guide rod extends to the outside of the sliding groove.

[0014] By adopting the above technical solution, the guide rod and sliding groove can limit the movement of the moving block and prevent it from tilting when moving inward.

[0015] The present invention is further configured such that the interior of the double-walled corrugated pipe is coated with an anti-corrosion coating.

[0016] By adopting the above technical solution and applying anti-corrosion coating, the corrosion resistance and moisture resistance of the double-wall corrugated pipe can be improved.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. This utility model first fixes the device between the bottle flake hopper discharge pipe and the body feed hopper. The device sends nitrogen gas in from the other end of the nitrogen gas inlet pipe. After the nitrogen gas is sent in, it enters the distribution pipe and is sprayed upward from the blowing port. After the nitrogen gas is sprayed out, it can blow away the air brought in when the bottle flakes fall. The blown-away air and excess nitrogen gas are released from the vent hole, which can reduce the air content in the material, reduce the possibility and probability of product oxidation and yellowing, and improve the quality of the product.

[0019] 2. This utility model utilizes the principle that when the double-walled corrugated pipe is subjected to vibration and impact, it deforms inward and drives the fixed plate to move. When the fixed plate moves, it drives the moving block to move into the fixed frame through the fixing of the connecting rod. When the fixed frame moves inward, it will compress the fixed spring and damper. When the fixed spring and damper are compressed and contracted, they will absorb and cancel the force energy, thus achieving good stability, reducing the damage caused by vibration and impact to the device, extending the service life of the device, and making it highly practical.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 A nitrogen protection device for bottle flakes includes a double-walled corrugated pipe 1. A connecting cylinder 2 and a distribution pipe 4 are respectively bolted to the top and inside of the double-walled corrugated pipe 1. A vent hole 3 is opened on the surface of the connecting cylinder 2, and an air blowing port 5 is opened on the surface of the distribution pipe 4. A nitrogen inlet pipe 6 communicating with the distribution pipe 4 is installed through the surface of the double-walled corrugated pipe 1. A valve 7 is installed on the surface of the nitrogen inlet pipe 6. The device is first fixed between the bottle flake hopper discharge pipe and the bottle flake feed hopper. The device sends nitrogen gas inward from the other end of the nitrogen inlet pipe 6. After the nitrogen gas is sent in, it enters the distribution pipe 4 and is sprayed upward from the air blowing port 5. After the nitrogen gas is sprayed out, it can blow away the air brought in when the bottle flakes fall. The blown-away air and excess nitrogen are released from the vent hole 3, which can reduce the air content in the material, reduce the possibility and probability of product oxidation and yellowing, and improve product quality.

[0029] refer to Figure 1 , Figure 2 and Figure 5The top of the surface of the connecting cylinder 2 and the bottom of the surface of the double-walled corrugated pipe 1 are respectively fixedly sleeved with a first flange 13 and a second flange 14. The first flange 13 and the second flange 14 make it easy for personnel to fix the device between the bottle flake hopper discharge pipe and the feed hopper with screws.

[0030] refer to Figure 1 and Figure 2 A nitrogen flow meter 15 is installed on the surface of the nitrogen inlet pipe 6. The nitrogen flow meter 15 makes it easy for personnel to observe the flow of nitrogen in the nitrogen inlet pipe 6.

[0031] refer to Figure 2 and Figure 3 The interior of the double-wall corrugated pipe 1 is coated with an anti-corrosion coating. The anti-corrosion coating improves the corrosion resistance and moisture resistance of the interior of the double-wall corrugated pipe 1.

[0032] Brief description of the usage process: First, fix the device between the bottle flake hopper discharge pipe and the feed hopper. The device sends nitrogen gas in from the other end of the nitrogen gas inlet pipe 6. After the nitrogen gas is sent in, it will enter the distribution pipe 4 and be sprayed upward from the blowing port 5. After the nitrogen gas is sprayed out, it can blow away the air brought in when the bottle flakes fall. The blown-away air and excess nitrogen gas will be released from the vent 3.

[0033] Example 2:

[0034] refer to Figure 1 , Figure 2 and Figure 4 A bottle-mounted nitrogen protection device is disclosed. A fixed plate 8 is fixedly fitted to both the top and bottom ends of a double-walled corrugated pipe 1. Two fixed frames 9 are provided on the surface of the double-walled corrugated pipe 1. Two movable blocks 10 are installed inside the fixed frames 9. A connecting rod 11 is installed between one side of the movable block 10 and the fixed plate 8, and a fixed spring 12 is bolted to the other side of the movable block 10 and the fixed frame 9 via a spring fixing plate. When the double-walled corrugated pipe 1 is subjected to vibration and impact, it deforms inward and drives the fixed plate 8 to move. When the fixed plate 8 moves, it drives the movable block 10 to move into the fixed frame 9 under the fixation of the connecting rod 11. When the fixed frame 9 moves inward, it compresses the fixed spring 12 and the damper 16. When the fixed spring 12 and the damper 16 are compressed, they absorb and cancel out the force energy, achieving good stability, reducing the damage caused by vibration and impact to the device, extending the service life of the device, and demonstrating high practicality.

[0035] refer to Figure 4 A damper 16 is installed between the other side of the moving block 10 and the fixed frame 9. The damper 16 can suppress the jumping of the fixed spring 12 and consume the kinetic energy stored in the fixed spring 12, thereby reducing the resonance amplitude and improving stability.

[0036] refer to Figure 1 and Figure 4 A guide rod 17 is installed on the front of the movable block 10, and a sliding groove is provided on the front of the fixed frame 9. The other end of the guide rod 17 extends to the outside of the sliding groove. Through the setting of the guide rod 17 and the sliding groove, the movable block 10 can be limited to prevent the movable block 10 from tilting when it moves inward.

[0037] Brief description of the usage process: When the double-walled corrugated pipe 1 is subjected to vibration and impact, it will deform inward and drive the fixed plate 8 to move. When the fixed plate 8 moves, it will drive the moving block 10 to move into the fixed frame 9 under the fixation of the connecting rod 11. When the fixed frame 9 moves inward, it will press the fixed spring 12 and the damper 16. When the fixed spring 12 and the damper 16 are compressed and contracted, they will absorb and cancel the force energy.
