Description

Technical Field

[0001] This utility model relates to the field of modified polyphenylene sulfide plastic granule production technology, specifically a drying device for modified polyphenylene sulfide plastic granules. Background Technology

[0002] Modified polyphenylene sulfide (PPS) plastic granules are a type of high-performance engineering plastic granules. They have a high heat distortion temperature and can be used for a long time in high-temperature environments above 200℃. They can withstand even higher temperatures in the short term and can withstand multiple high-temperature cycles without significant performance changes. They can be widely used in the electronics and electrical fields, the automotive industry, and other industrial fields.

[0003] In the current production process, modified polyphenylene sulfide (PPS) plastic granules need to be dried in a drying oven. However, the plates in the existing drying ovens are usually fixed and their distance cannot be adjusted. This makes it difficult to adapt to the different sizes of modified PPS plastic granules, thus making it difficult to achieve the best drying effect. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for modified polyphenylene sulfide plastic granules to solve the problems mentioned in the background art. To solve the above technical problems, this invention is achieved through the following technical solution:

[0005] This utility model relates to a drying device for modified polyphenylene sulfide plastic granules, comprising:

[0006] A drying oven and a door, wherein the door is movably connected to the front of the drying oven;

[0007] The size adaptation adjustment component includes a baffle frame, a metal mesh, a receiving block, a first slot, a second slot, and a rod. The baffle frame is movably connected in the drying oven. The metal mesh is fixedly installed at the bottom of the baffle frame. The receiving blocks are fixedly connected to both sides of the front end of the baffle frame. The first slot is opened through the receiving block. The second slot is opened in the drying oven. The rod is movably connected in the first slot and the second slot.

[0008] Furthermore, a total of sixteen second slots are provided, symmetrically distributed in the drying oven, with eight slots on each side.

[0009] Furthermore, the size adaptation adjustment assembly also includes a pull plate, and the front part of the insertion rod is fixedly connected to the pull plate.

[0010] Furthermore, it also includes a protective component, which includes a nitrogen flow box and an exhaust trough. The nitrogen flow box is fixedly connected in the drying oven, and the exhaust trough is opened through the side of the nitrogen flow box.

[0011] Furthermore, there are a total of eight nitrogen flow boxes.

[0012] Furthermore, the protection assembly also includes a circular groove, a branch pipe, a main pipe, an L-shaped pipe, a nitrogen storage tank, and a pump for extraction and pressurization. A circular groove is formed through the other side of the nitrogen flow box. A branch pipe is fixedly inserted into the circular groove. The branch pipe is fixedly inserted into the drying box. The main pipe is fixedly connected to the side of the branch pipe. The L-shaped pipe is fixedly connected to the side of the main pipe. The nitrogen storage tank is movably inserted into the bottom of the L-shaped pipe. The pump for extraction and pressurization is fixedly connected to the middle of the L-shaped pipe.

[0013] Furthermore, the protection assembly also includes a ball valve, which is installed on the diversion pipe.

[0014] This utility model has the following beneficial effects:

[0015] This invention, through the cooperation of the insert rod, the first slot, and the second slot, enables the installation of different numbers of baffle frames and metal meshes in the drying oven, thereby allowing for adjustable installation distances between the metal meshes. When the modified polyphenylene sulfide (PPS) plastic particles to be dried have a large particle size, the number of baffle frames and metal meshes can be appropriately reduced, thus appropriately increasing the distance between adjacent metal meshes. This creates more space to ensure sufficient contact between hot air and the particles. Conversely, when the modified PPS plastic particles to be dried have a small particle size, all metal meshes can be installed, achieving relatively tight stacking. In summary, this invention can flexibly change the stacking space according to the particle size of the modified PPS plastic particles, allowing modified PPS plastic particles of different sizes to be dried in a suitable space, improving drying efficiency and effectiveness.

[0016] Based on the aforementioned beneficial effects, under the action of the extraction and pressurization pump, nitrogen stored in the nitrogen storage tank can be applied to the surface of the modified polyphenylene sulfide plastic particles through the L-shaped pipe, the main pipe, and the branch pipe. Nitrogen is an inert gas, which can form a protective gas film on the surface of the modified polyphenylene sulfide plastic particles, isolating oxygen and preventing oxidation reaction of the modified polyphenylene sulfide plastic particles during high-temperature drying. This protects the performance and quality of the modified polyphenylene sulfide plastic particles and avoids problems such as color change and mechanical property degradation caused by oxidation.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-5 As shown, this utility model is a drying device for modified polyphenylene sulfide plastic granules, comprising:

[0030] Drying oven 101 and oven door 102, with oven door 102 movably connected to the front of drying oven 101;

[0031] The size adaptation adjustment component includes a baffle 201, a metal mesh 202, a receiving block 203, a first slot 204, a second slot 205, and a rod 206. The baffle 201 is movably connected in the drying oven 101. The metal mesh 202 is fixedly installed at the bottom of the baffle 201. The receiving blocks 203 are fixedly connected to both sides of the front end of the baffle 201. The first slot 204 is opened through the receiving block 203. The second slot 205 is opened on the drying oven 101. The rod 206 is movably connected in the first slot 204 and the second slot 205.

[0032] The drying oven 101, model HG-101-2A, has a modified polyphenylene sulfide plastic granule placement plate structure formed by the baffle frame 201 and the metal mesh 202. The baffle frame 201 prevents the modified polyphenylene sulfide plastic granules from falling off the metal mesh 202. The metal mesh 202 facilitates the flow of hot air. The receiving block 203 ensures the opening of the first slot 204. The insertion rod 206, the first slot 204, and the second slot 205 work together to ensure the movable installation of the baffle frame 201 and the metal mesh 202.

[0033] The second slot 205 has a total of sixteen slots, which are symmetrically distributed at the drying oven 101, with eight slots distributed on one side.

[0034] The number of second slots 205 ensures the adjustment of the distance between metal meshes 202.

[0035] The size adaptation adjustment assembly also includes a pull plate 207, and the front of the insert rod 206 is fixedly connected to the pull plate 207;

[0036] The pull plate 207 is designed to make it easy for the user to pull the plug 206.

[0037] Working principle: If the modified polyphenylene sulfide plastic granules to be dried have a small particle size, take eight baffle frames 201 and metal mesh 202, spread the modified polyphenylene sulfide plastic granules evenly on the metal mesh 202, then insert the baffle frames 201 into the drying chamber 101, and then insert the insert rods 206 into the first slot 204 and the second slot 205 in sequence. Then turn on the switch in the drying chamber 101 to start the drying process. If the modified polyphenylene sulfide plastic granules to be dried have a large particle size, spread the modified polyphenylene sulfide plastic granules evenly on four metal meshes 202, then insert the baffle frames 201 into the drying chamber 101, staggering them by one second slot 205, and finally start the drying process.

[0038] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0039] The protective component includes a nitrogen flow box 301 and an exhaust groove 302. The nitrogen flow box 301 is fixedly connected in the drying oven 101, and the exhaust groove 302 is opened through the side of the nitrogen flow box 301.

[0040] The nitrogen flow box 301 is used to transfer nitrogen, and the gas outlet 302 is used to discharge nitrogen from the nitrogen flow box 301.

[0041] There are a total of eight nitrogen flow boxes (301).

[0042] The number of nitrogen flow boxes 301 is set to ensure that nitrogen covers all modified polyphenylene sulfide plastic particles.

[0043] The protective assembly also includes a circular groove 303, a branch pipe 304, a main pipe 305, an L-shaped pipe 306, a nitrogen storage tank 307, and a pumping and pressurizing pump 308. A circular groove 303 is opened through the other side of the nitrogen flow box 301. A branch pipe 304 is fixedly inserted in the circular groove 303. A drying box 101 is fixedly inserted in the branch pipe 304. The main pipe 305 is fixedly connected to the side of the branch pipe 304. An L-shaped pipe 306 is fixedly connected to the side of the main pipe 305. A nitrogen storage tank 307 is movably inserted into the bottom of the L-shaped pipe 306. The pumping and pressurizing pump 308 is fixedly connected to the middle of the L-shaped pipe 306.

[0044] The circular groove 303 provides a guarantee for the installation of the branch pipe 304. The main pipe 305 and the L-shaped pipe 306 are used to transmit nitrogen. The nitrogen storage tank 307 is used to store nitrogen. The extraction and pressurization pump 308 is used to extract nitrogen.

[0045] The protection components also include a ball valve 309, which is mounted on the diversion pipe 304;

[0046] The ball valve 309 can control the flow state of the individual diversion pipe 304, thereby adapting to different installation quantities of metal mesh 202 and preventing nitrogen waste.

[0047] Working principle: If all metal meshes 202 are installed and in use, all eight ball valves 309 are opened simultaneously, and the extraction and pressurization pump 308 is turned on to extract nitrogen from the nitrogen storage tank 307. At this time, the nitrogen flows through the L-shaped pipe 306, the main pipe 305, and the branch pipe 304 into the nitrogen flow box 301. Finally, it acts on the surface of the modified polyphenylene sulfide plastic particles through the gas outlet groove 302 to form a protective gas film. If the number of metal meshes 202 installed is reduced, the corresponding ball valve 309 above the metal meshes 202 is opened.
