Description

Technical Field

[0001] The utility model relates to the field of conveying pipelines, in particular to a vortex pipeline used for conveying glass fiber reinforced engineering plastic particles. Background Art

[0002] Glass fiber reinforced plastic is a new type of high-performance plastic product. It has high strength and hardness, corrosion resistance, heat resistance, cold resistance, weather resistance, impact resistance and other excellent properties, which can meet the needs of different industries. The production of glass fiber reinforced engineering plastics mainly uses a twin-screw extruder to thermoplasticize engineering plastics, and then blends them with glass fiber alloys and extrude granules to obtain granular materials. The particles screened by the vibrating screen need to be strongly conveyed by a fan and transported to the storage tank through a pipeline.

[0003] Most of the pipes currently used are stainless steel pipes with a diameter of 20 cm. Due to the high rigidity of glass fiber reinforced engineering plastic particles, at the corners of the stainless steel pipes, they are transported by the large airflow from the fan, causing the plastic particles to strongly impact and wear the pipe wall at the corners of the stainless steel pipes, which will cause pipe wear and rupture in a short period of time. The most serious problem is that the metal powder generated by the strong impact and wear is brought into the plastic particles, seriously affecting the quality of the product.

[0004] In order to solve the problem of impact wear on the corners of pipelines caused by the transportation of plastic particles in the production of modified glass fiber reinforced engineering plastics, the utility model designs a vortex pipeline. A vortex structure is designed at the corner of the pipeline. Granular materials can be stored in the vortex to prevent particles at the corners from directly hitting the pipe wall. At the same time, the vortex structure can effectively buffer the impact speed of the particles. Since the vortex pipeline is made of polyphenylene sulfide, it has excellent high strength, high rigidity, fatigue resistance and creep resistance, so that the vortex pipeline can withstand greater pressure and impact force, and can maintain stable size and shape during long-term use.

Noise reduction pads are installed in the inner cavities of the first noise reduction shell and the second noise reduction shell, and the noise reduction pads are made of polyester fiber.

[0008] Preferably, the inner cavity of the second noise reduction shell is provided with four positioning slots, the inner cavities of the positioning slots are plugged with positioning plates, and the front side of the positioning plates is fixedly connected to the back side of the first noise reduction shell.

[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0019] The following is combined with Figure 1-3 To further explain this application,

[0020] The present application discloses a vortex pipe for conveying glass fiber reinforced engineering plastic particles. Figure 1 and Figure 2 A vortex pipe for conveying glass fiber reinforced engineering plastic particles includes a vortex pipe 1, which includes a pipe body 101. Flanges 102 are installed at the bottom and right side of the pipe body 101. A feed trough 104 is opened at the bottom of the inner cavity of the pipe body 101. The top of the feed trough 104 is connected to a vortex storage trough 105. The right side of the feed trough 104 is connected to a discharge trough 103. The material of the pipe body 101 is polyphenylene sulfide.

[0021] Reference Figure 1 and Figure 3 , the front and back sides of the surface of the tube body 101 are both installed with a noise reduction mechanism 2, and the noise reduction mechanism 2 includes a first noise reduction shell 201 and a second noise reduction shell 202. The inner cavities of the first noise reduction shell 201 and the second noise reduction shell 202 are movably connected to the surface of the tube body 101, and the inner sides of the first noise reduction shell 201 and the second noise reduction shell 202 are tightly fitted. The inner cavities of the first noise reduction shell 201 and the second noise reduction shell 202 are both installed with noise reduction pads 204, which are polyester fibers. The tube body 101 is wrapped by the arrangement of the first noise reduction shell 201 and the second noise reduction shell 202 to reduce the transmission of noise generated during the use of the tube body 101. At the same time, the noise generated during the use of the tube body 101 is absorbed by the arrangement of the noise reduction pad 204, thereby further reducing the diffusion of noise.

[0022] Reference Figure 3 The inner cavity of the second noise reduction shell 202 is provided with a positioning groove 203, and the number of the positioning grooves 203 is four. The inner cavity of the positioning groove 203 is plugged with a positioning plate 205, and the front side of the positioning plate 205 is fixedly connected to the back side of the first noise reduction shell 201. Through the setting of the positioning groove 203, the positioning plate 205 can be inserted into the interior of the second noise reduction shell 202, so that when the inner sides of the first noise reduction shell 201 and the second noise reduction shell 202 are fitted together, the connection between the first noise reduction shell 201 and the second noise reduction shell 202 can be made more stable, further improving the stability of the connection between the first noise reduction shell 201 and the second noise reduction shell 202.

[0023] Reference Figure 1 and Figure 3 The tops of the first noise reduction shell 201 and the second noise reduction shell 202 are both installed with a fixing mechanism 3, and the fixing mechanism 3 includes a connecting seat 302, the bottom of the connecting seat 302 is fixedly connected to the tops of the first noise reduction shell 201 and the second noise reduction shell 202 respectively, and the surface of the connecting seat 302 is movably connected with the fixing seat 301, and the bottom of the fixing seat 301 is movably connected to the tops of the first noise reduction shell 201 and the second noise reduction shell 202 respectively. The position of the connecting seat 302 is limited by the setting of the fixing seat 301, thereby limiting the position of the first noise reduction shell 201 and the second noise reduction shell 202 by the setting of the connecting seat 302, preventing the surfaces of the first noise reduction shell 201 and the second noise reduction shell 202 from detaching.

[0024] Reference Figure 3 The inner cavity of the connecting seat 302 is provided with a sliding groove 303, and the inner cavity of the sliding groove 303 is clamped with a fixing plate 304. The surface of the fixing plate 304 is fixedly connected to the inner cavity of the fixing seat 301. Through the setting of the sliding groove 303, the fixing plate 304 can slide inside the connecting seat 302, so that during the sliding process of the fixing plate 304, the fixing effect between the fixing seat 301 and the connecting seat 302 can be improved, preventing the fixing seat 301 from detaching from the surface of the connecting seat 302.

[0025] Working principle: First, by setting up a vortex storage tank 105, the plastic particles can be stored first inside the vortex storage tank 105 after entering from the feed tank 104, thereby preventing the plastic particles at the corners from directly hitting the inner wall of the tube body 101. After the storage of the plastic particles inside the vortex storage tank 105 is completed, the subsequent plastic particles will pass through the feed tank 104 and be discharged directly from the vortex storage tank 105, which effectively buffers the impact speed of the plastic particles, reduces the speed of pipeline wear and rupture, improves the service life of the pipeline, and prevents metal powder generated by pipeline wear from bringing in plastic particles, affecting the quality of the product. At the same time, during the use of the tube body 101, by holding the first noise reduction shell 201 and the second noise reduction shell 202 and moving them inward, the first noise reduction shell 201 and the second noise reduction shell 202 are sleeved on the surface of the tube body 101. When the first noise reduction shell 201 and the second noise reduction shell 202 are closed, the noise reduction pad 204 will fit on the surface of the tube body 101, thereby The noise reduction pad 204 absorbs the noise generated during the use of the tube body 101, and reduces the diffusion of noise during the use of the tube body 101 through the first noise reduction shell 201 and the second noise reduction shell 202, and drives the positioning plate 205 to move during the movement of the first noise reduction shell 201. When the first noise reduction shell 201 and the second noise reduction shell 202 are in contact with each other, the positioning plate 205 will be inserted into the interior of the positioning groove 203 to improve the stability of the first noise reduction shell 201 and the second noise reduction shell 202. Finally, the fixing seat 301 is sleeved on the surface of the connecting seat 302 to further limit the position of the first noise reduction shell 201 and the second noise reduction shell 202 to prevent the position of the first noise reduction shell 201 and the second noise reduction shell 202 from shifting. The fixing plate 304 slides inside the slide groove 303 to fix the position of the fixing seat 301, so that the fixing seat 301 can be stably attached to the surface of the connecting seat 302 to prevent the position of the fixing seat 301 from shifting.
