Description

Technical Field

[0001] The invention relates to the technical field of polyvinyl chloride resin production equipment, in particular to a polyvinyl chloride resin production device. Background Art

[0002] Polyvinyl chloride, referred to as PVC, is a polymer formed by the free polymerization mechanism of vinyl chloride monomer in the presence of initiators such as peroxides and azo compounds, or under the action of light or heat. Polyvinyl chloride has a wide range of uses, such as food and drug packaging and children's toys, so the production volume of polyvinyl chloride is also huge. When producing polyvinyl chloride resin, the raw materials are often stirred by a stirring device to promote the polymerization reaction of the raw materials to form polyvinyl chloride resin;

[0003] The authorized patent number CN214537206U discloses a polyvinyl chloride resin drying device. The device mainly adopts a designed stirring device, a filter screen, a first bearing, a fixing rod, a nut, a motor, a movable plate, a hinge, and a fixing block. First, the polyvinyl chloride resin to be dried is placed inside the stirring device. At this time, the movable plate on the top of the stirring device needs to be opened. At this time, the nut is twisted to twist the nut out from the inside of the movable plate. This is to better allow the polyvinyl chloride resin to be placed inside the stirring device, effectively solving the problem that the polyvinyl chloride resin is not heated evenly, resulting in the polyvinyl chloride resin being unable to be used normally. However, when the device is actually used, the following defects still exist;

[0004] The above patent mainly stirs and dries the polyvinyl chloride resin through a drying structure, thereby solving the problem of uneven heating of the polyvinyl chloride resin. However, after the mixing reaction of the polyvinyl chloride resin, it is often necessary to centrally transport it to a drying device. However, the actual transfer of the resin is not convenient, and the centrally transferred resin particles are prone to stick to each other, resulting in the inability of the dried resin to be fully heated, affecting the comprehensive performance of the resin production. In addition, when the resin is discharged, the resin is prone to pile up and cannot be discharged normally, and it is easy to cause blockage in the discharge port, affecting the overall processing efficiency of the polyvinyl chloride resin.

[0018] Compared with the prior art, the present invention provides a production device for polyvinyl chloride resin, which has the following beneficial effects:

[0019] 1. The present invention can combine stirring and quantitative feeding through the structural coordination of the quantitative stirring mechanism to promote efficient mixing of the polyvinyl chloride resin in the reactor, and avoid the problem of excessive material being put in at one time, resulting in material adhesion and inability to mix thoroughly, by means of the material feeding of the feeding trough and the quantitative feeding of the turntable.

[0020] 2. The present invention utilizes the structural coordination of the centrifugal screening mechanism to promote the stirring of the resin particles introduced into the interior of the filter screen cylinder under the linkage of two groups of synchronously rotating structures. At the same time, a hot air blower is used to heat the surface of the rotating filter screen cylinder, so that the resin particles filtered by the filter screen cylinder are fully heated. The filtering characteristics of the filter screen cylinder are utilized to promote the hot gas to pass through the filter screen cylinder and fill the filter screen cylinder. The two groups of rotating scrapers and the centrifugally rotating filter screen cylinder are coordinated to fully stir the resin particles so that the bonded resin particles can be naturally separated and shaken out. The filtering structure is used to allow the resin particles to form a penetration effect under the scraping and squeezing state of the scraper, so that the particles filtered by the filter screen cylinder are evenly heated, thereby improving the drying efficiency of the resin particles.

[0021] 3. The present invention promotes the introduction of resin particles filtered out by the centrifugal screening mechanism into the inner side of the spiral guide trough through the structural coordination of the vibrating discharge mechanism, and utilizes the spiral structure of the spiral guide trough to extend the discharge path of the resin particles. In this state, the hot gas supplied by the hot air blower in the centrifugal screening mechanism can be introduced into the vibrating discharge mechanism, and turbulently stirred by the air guide blades, so that the hot gas is uniformly covered in the flow path of the spiral guide trough, so as to perform secondary drying on the resin particles in the discharge state. At the same time, under the intermittent vibration of the vibration bracket, the discharge rate of the resin particles is increased, and adhesion and stagnation in the path of the spiral guide trough are avoided, so that the polyvinyl chloride resin is orderly discharged under the guidance of the structure, and the heating effect of the resin surface is greatly improved, and the resin drying efficiency is further enhanced.

[0042] Embodiment 1, as Figure 1-3 As shown, when the resin particles are introduced into the installation bin 31 through the structure of the quantitative stirring mechanism 4, the resin particles can be directly placed into the filter screen cylinder 310 for heating and drying through the guidance of the guide tube 41, without the need to centrally collect and transport the resin particles. The centrifugal rotation of the filter screen cylinder 310 is used to force the bonded materials to separate naturally under the heating state and the contact and extrusion of the two sets of scrapers 39, and the hot gas output by the hot air blower 7 is discharged from top to bottom into the filter screen cylinder 310, so as to fully dry the centrifugally rotated and separated resin particles, thereby improving the drying effect of the resin particles and enhancing the subsequent production efficiency.

[0043] Embodiment 2, as Figure 2-4As shown, when the resin particles are gradually filtered and seeped from the filter screen cylinder 310, the guide plate 6 can be used to guide the resin particles to be evenly placed in the spiral flow channel of the spiral guide groove 23.

The second driver 211 is started to drive the air guide blade 24 to rotate, so that the hot gas flowing from the installation bin 31 from top to bottom is evenly covered on the inner side of the spiral guide groove 23, so that the resin particles in the flowing state are further heated. The secondary heating and drying structure is used to not only utilize the waste heat inside the device, but also improve the stability of resin discharge, avoid blockage of large-scale resin discharge, and make the drying more comprehensive, thereby enhancing the qualified rate of polyvinyl chloride resin production and processing.

[0044] Working principle: In the production device of polyvinyl chloride resin;

[0045] When the polyvinyl chloride resin is processed and produced, the raw materials are first placed in the reactor 43, and the introduced raw materials are distributed and transported through the distribution trough 44 inside the reactor 43. Then, the stirring motor 45 is started to drive the stirring rod 47 and the turntable 46 to rotate, so that the two groups of quantitative ports are intermittently connected with the distribution trough 44 while the turntable 46 rotates, so that the raw materials are quantitatively discharged, and with the stirring of the stirring rod 47 and the heating inside the reactor 43, the raw materials placed in the reactor 43 are stirred and heated for reaction, and the inner wall of the reactor 43 is continuously scraped and brushed under the rotation of the two groups of scraping plates 48 to prevent the raw materials from adhering to the inner wall of the reactor 43, so that the polyvinyl chloride resin raw materials are mixed and reacted in the reactor 43, and then introduced into the filter screen cylinder 310 for drying through the opening of the discharge valve 42 and the transportation of the guide pipe 41;

[0046] The hot air blower 7 is started to heat the internal space of the installation chamber 31 and introduce hot gas to the surface and the interior of the filter screen cylinder 310 opposite to the vertical surface. During this period, the first bevel gear 34 is driven to rotate by the start of the driving motor 32, so that the first bevel gear 34 is respectively meshed with the two sets of second bevel gears 35. When one set of the second bevel gears 35 is meshed, it drives the rotating rod 36 and the two sets of scrapers 39 to rotate forward, so that the two sets of scrapers 39 scrape and squeeze the inner wall of the filter screen cylinder 310 and the resin particles. After the other set of the second bevel gears 35 is meshed with the first bevel gear 34, it drives a set of rotating seats 37 to rotate on the four sets of guide blocks 3 on the same side. 3 and the sliding guide of the annular guide groove 38, so that the rotating seat 37 drives the filter screen cylinder 310 to rotate in the opposite direction. At this time, the filter screen cylinder 310 and the two groups of scrapers 39 that rotate in opposite directions cooperate with each other to dry the resin particles entering the filter screen cylinder 310 and separate the resin particles naturally. Then, the two groups of scrapers 39 squeeze the resin particles to force the separated resin particles to seep out of the filter screen cylinder 310 and be discharged into the housing 1 under the guidance of the vibration type discharge mechanism 2. This structure uses filtering and centrifugal rotation to evenly dry the material and improve the drying efficiency of the polyvinyl chloride resin particles.

[0047] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
