Description

Technical Field

[0001] The invention relates to the technical field of plastic particle processing, in particular to a chlorinated polyethylene particle dehydration and drying device and method. Background Art

[0002] Chlorinated polyethylene, as a high-performance polymer material, is widely used in many industrial fields. In the production process of particles, dehydration and drying are crucial links. After synthesis and preliminary processing, the particles usually have a large amount of water on the surface, and there may be certain solvent residues inside. If they are not fully dehydrated and dried, the water and solvent will seriously affect the chemical stability and physical properties of the particles. Therefore, a dehydration and drying device is needed. The most common dehydration and drying device is the centrifugal dehydration method.

[0003] After searching, for example, the utility model patent with Chinese patent announcement number CN220864468U discloses a plastic particle dehydration and drying device, including supporting legs, a protective box, a dehydration barrel, a rotating motor, a mixing component and a drying box, wherein the protective box is arranged on the supporting legs, and a rotating seat is provided at the lower end of the dehydration barrel. The dehydration barrel is rotatable through the rotating seat and is arranged in the middle of the bottom wall of the protective box. The rotating motor is arranged in the middle of the lower bottom wall of the protective box, and the output shaft of the rotating motor is connected to the rotating seat. The mixing component is arranged in the middle of the upper top wall of the protective box, and the lower end of the mixing component extends into the dehydration barrel. The drying box is symmetrically arranged in the middle of the two side walls of the protective box, and a drying pipe is provided on the drying box, and the drying pipe extends into the protective box. A plurality of groups of air shower heads are arranged at intervals on the drying pipe, and the plurality of groups of air shower heads correspond to the dehydration barrel.

[0004] In actual application scenarios, the raw materials for the production of plastic particles come from a wide range of sources and the processing steps are complex, resulting in impurities such as metal debris often mixed into the particles. However, the device does not set up any impurity treatment process for the plastic particles before entering the dehydration barrel. The untreated plastic particles directly enter the dehydration barrel. In the subsequent dehydration and drying process, impurities such as metal debris will cause serious friction and collision with key components inside the device such as the dehydration barrel and mixing components, which will undoubtedly accelerate the wear of the components and greatly reduce the normal service life of the components. Therefore, a chlorinated polyethylene particle dehydration and drying device and method are proposed. Summary of the invention

Under the action of the cross bar and the breaking rod, the plastic particles are broken up to reduce the blockage in the feed pipe due to wet sticking and improve the smoothness of feeding.

[0038] like Figure 2 and Figure 4 As shown, the screening device 11 includes a screen frame 14, a mounting frame 15, a spring 16, a slot 17, a protrusion 18 and a fixing rod 19.

By providing the slot 17, the protrusion 18 and the fixing rod 19, it is convenient to fix and disassemble the screen frame 14. The raised part of the protrusion 18 can be inserted into the slot 17. The surface of the protrusion 18 is provided with a threaded hole adapted to the fixing rod 19.

When the motor 202 is running, the worm 203 is driven to rotate, and the stirring rod 206 is driven to rotate through the engagement of the bevel gear 1 204 and the bevel gear 205. The engagement of the turbine 207 and the worm 203 drives the rotating drum 23 to rotate, so that the particles can be evenly heated during the tumbling process, further improving the overall efficiency of dehydration and drying, and shortening the processing time.

[0043] A method for using a chlorinated polyethylene particle dehydration and drying device, including a method for using the chlorinated polyethylene particle dehydration and drying device, the method for using is as follows:

[0044] 1) Chlorinated polyethylene particles are put into the feed pipe, and the particles' own gravity causes the breaking rod to rotate, and the particles that stick together are initially broken up, and then enter the screen frame 14 inside the top box 1.

[0045] 2) At this time, the servo motor 101 in the auxiliary component 13 drives the rotating rod 102 to rotate back and forth, and under the transmission of the pulley 104 and the transmission belt 105, the air supply pipe 12 and the eccentric wheel 103 are driven to swing back and forth. The eccentric wheel 103 continuously knocks the screen frame 14 to make the screen frame 14 shake, so that the plastic particles are separated from the metal impurities. At the same time, the pump body 25 transports the hot air in the drying box 24 to the air supply pipe 12, so that the heat is evenly sprayed on the screen frame 14, so as to achieve the effect of preliminary heating while screening.

[0046] 3) Afterwards, the particles enter the drum 23, and the pump body 25 transports the hot air to the heat chamber 21 and diffuses it to the drum 23 through the outlet 22. At the same time, the power assembly 26 drives the stirring rod 206 and the drum 23 to rotate synchronously in a reverse and forward manner.
