[0019] Beneficial effects of the utility model:

[0020] (1) The utility model realizes the dehydration treatment of plastic particles through a drying component. First, the plastic particles are transported to the conveyor belt through the feed bin, and then the conveyor belt transports the plastic particles to the inside of the dehydration box. After reaching the bottom of the water-absorbing sponge, the telescopic cylinder drives the water-absorbing sponge to descend and wrap the plastic particles. The water-absorbing sponge can be used to absorb the moisture on the surface of the plastic particles during wrapping.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Please refer to the attached picture Figure 1-Figure 6 As shown, a dehydrator for cleaning plastic-made particles in the embodiment of the utility model comprises a dehydration box body 1 and a feed bin 21, and also comprises: a conveying unit arranged inside the dehydration box body 1; the conveying unit comprises a conveyor belt 42; the conveyor belt 42 is driven by a driving force; a drying component 6 arranged at the bottom of the dehydration box body 1; the drying component 6 comprises a fan blade 62; the fan blade 62 is driven to rotate by a driving force; an electric heating pipe 63 is fixedly connected to the side wall of the dehydration box body 1 above the fan blade 62; the fan blade 62 is arranged below the conveyor belt 42; a telescopic cylinder 5 is fixedly connected to the top of the dehydration box body 1; an end of the telescopic cylinder 5 away from the dehydration box body 1 is fixedly connected to a water-absorbing sponge 51;

[0032] During operation, in the prior art, when the centrifugal force is generated by the rotation of the drum to dehydrate the plastic particles, the plastic particles will continue to shake in the drum. During the shaking process, some of the plastic particles will collide with each other. The impact force generated by the collision may cause the plastic particles to break. After the dehydration work is completed, more broken plastic particles will be produced at the bottom of the drum, thereby affecting the subsequent cleaning and reducing the quality of the plastic particles. In order to prevent such incidents from happening, first, the plastic particles are transported to the conveyor belt 42 through the feed bin 21, and then the conveyor belt 42 transports the plastic particles to the inside of the dehydration box. After reaching the bottom of the water-absorbing sponge 51, the conveyor belt 42 stops working. At this time, the telescopic cylinder 5 drives the water-absorbing sponge 51 to descend, and the plastic particles are transported to the bottom of the drum. Wrapping, when wrapping, the water on the surface of the plastic particles can be absorbed by the water-absorbing sponge 51. After the surface water is absorbed, the conveyor belt 42 starts working again to convey the plastic particles to the top of the drying component 6. At this time, the conveyor belt 42 stops working again. After reaching the top of the drying component 6, the electric heating tube 63 in the drying component 6 starts working to fill the interior of the dehydration box body 1 with high temperature. While working, the fan blade 62 is driven to rotate, and wind force is generated during rotation to transfer the high temperature to the plastic particles, thereby drying the plastic particles. Through the arrangement of the water-absorbing sponge 51 and the electric heating tube 63, the plastic particles can be dried in a static state, thereby avoiding collision of the plastic particles during drying, which leads to loss of the plastic particles.

[0033] like Figure 3 As shown, a feed shaft 22 is rotatably connected in the feed bin 21; a pusher blade 23 is fixedly connected to the feed shaft 22; a conveying pipe 25 is fixedly connected to the bottom of the feed bin 21; an end of the conveying pipe 25 away from the feed bin 21 is arranged above the conveyor belt 42;

[0034] During operation, after the plastic particles enter the feed bin 21, the feed shaft 22 is started to rotate, which drives the push paddle 23 to rotate. The plastic particles can be pushed by the push paddle 23 to fall from the feed pipe 25 to the conveyor belt 42 in sequence, avoiding the plastic particles from being concentrated on the conveyor belt 42, resulting in some plastic particles being covered and unable to be dehydrated.

[0035] like Figure 5 and Figure 6 As shown, a discharge assembly 7 is provided at the bottom of the dehydration box body 1; the discharge assembly 7 includes a material collecting bin 71; a filter drawer 72 is slidably connected in the material collecting bin 71; a waste drawer 73 is slidably connected in the material collecting bin 71 below the filter drawer 72;

[0036] During operation, the plastic particles will be limited in particle size during processing, which will result in defective plastic particles during production. After the plastic particles are dried, the conveyor belt 42 starts working again. When the plastic particles are conveyed to the end of the conveyor belt 42, they will fall onto the filter drawer 72. The filter drawer 72 can screen the plastic particles and filter out unqualified plastic particles. The unqualified plastic particles will fall into the waste drawer 73 below the filter drawer 72. Finally, the waste drawer 73 and the filter drawer 72 are pulled out to collect the finished products and defective products.

[0037] like Figure 6 As shown, a vibration groove 76 is provided on the side wall of the collecting bin 71; a telescopic spring 74 is fixedly connected in the vibration groove 76; a supporting plate 75 is fixedly connected to the end of the telescopic spring 74; and one end of the supporting plate 75 away from the telescopic spring 74 abuts against the filter drawer 72;

[0038] During operation, when plastic particles fall from the conveyor belt 42 onto the filter drawer 72, the filter drawer 72 will vibrate, and at the same time, the telescopic spring 74 will be squeezed. At the same time, the telescopic spring 74 will rebound, which can drive the filter drawer 72 to shake, and the plastic particles will be screened during the shaking process. In addition, through the setting of the telescopic spring 74, the filter drawer 72 can be driven to shake up and down, and the plastic particles can be moved during the shaking process, so as to prevent the plastic particles from clogging the filter drawer 72 and affecting the screening effect.

[0039] like Figure 1 As shown, the side wall of the dehydration box body 1 is rotatably connected to a transmission shaft 41; the conveyor belt 42 is sleeved on the transmission shaft 41; the side wall of the dehydration box is fixedly connected to a transmission motor 43; the transmission shaft 41 is driven to rotate by the transmission motor 43;

[0040] During operation, the transmission motor 43 drives the transmission shaft 41 to rotate, and during rotation, the conveyor belt 42 is used to convey the plastic particles to the bottom of the water-absorbing sponge 51 and the top of the electric heating tube 63, thereby achieving dehydration.

[0041] like Figure 3 As shown, a fan motor 64 is fixedly connected to the bottom of the dehydration box body 1; a fan shaft 61 is rotatably connected to the bottom of the dehydration box body 1; the fan blades 62 are fixedly connected to the fan shaft 61; a ventilation hole 11 is opened at the bottom of the dehydration box at the fan shaft 61; the fan shaft 61 is driven to rotate by the fan motor 64;

[0042] During operation, the fan shaft 61 is driven to rotate by the fan motor 64, and the fan blades 62 are driven to rotate during the rotation, thereby generating wind force to transfer high temperature to the plastic particles, thereby achieving dehydration.

[0043] like Figure 1 and Figure 2As shown, the bottom of the dehydration box body 1 and the bottom of the feed bin 21 are fixedly connected with a support leg 3; the bottom of the support leg 3 is fixedly connected with a rubber pad 31; the top of the feed bin 21 is fixedly connected with a feed pipe 24;

[0044] During operation, the support legs 3 can support the feed bin 21 and the dehydration box body 1, and the rubber pads 31 can prevent the support legs 3 from slipping. The feed pipe 24 is connected to the plastic particle cleaning equipment. After cleaning, the particles enter the feed bin 21 from the feed pipe 24 and are then transported to the conveyor belt 42 through the conveying pipe 25.

[0045] Working principle of the utility model: in the prior art, when the plastic particles are dehydrated by the centrifugal force generated by the rotation of the drum, the plastic particles will continue to shake in the drum, and some of the plastic particles will collide with each other during the shaking process. The impact force generated by the collision may cause the plastic particles to break. After the dehydration work is completed, more broken plastic particles will be produced at the bottom of the drum, thereby affecting the subsequent cleaning and reducing the quality of the plastic particles. In order to prevent such incidents from happening, first, the plastic particles are transported to the conveyor belt 42 through the feed bin 21, and then the conveyor belt 42 transports the plastic particles to the inside of the dehydration box. After reaching the bottom of the water-absorbing sponge 51, the conveyor belt 42 stops working, and the telescopic cylinder 5 drives the water-absorbing sponge 51 to descend, and the plastic particles are transported to the bottom of the drum. The plastic particles are wrapped, and the water on the surface of the plastic particles can be absorbed by the water-absorbing sponge 51 during wrapping. After the surface water is absorbed, the conveyor belt 42 starts working again to convey the plastic particles to the top of the drying component 6. At this time, the conveyor belt 42 stops working again. After reaching the top of the drying component 6, the electric heating tube 63 in the drying component 6 starts working to fill the interior of the dehydration box body 1 with high temperature. While working, the fan blade 62 is driven to rotate, and wind force is generated during rotation to transfer the high temperature to the plastic particles, thereby drying the plastic particles. Through the arrangement of the water-absorbing sponge 51 and the electric heating tube 63, the plastic particles can be dried in a stationary state, thereby avoiding collision of the plastic particles during drying, which leads to loss of the plastic particles.

[0046] Among them, the plastic particles are screened by the discharging component 7. The plastic particles will be limited in particle size during processing, which will result in defective plastic particles during production. After the plastic particles are dried, the conveyor belt 42 works again. When the plastic particles are conveyed to the end of the conveyor belt 42, they will fall onto the filter drawer 72. The filter drawer 72 can screen the plastic particles and screen out unqualified plastic particles. The unqualified plastic particles fall into the waste drawer 73 below the filter drawer 72. Finally, the waste drawer 73 and the filter drawer 72 are pulled out to collect the finished products and defective products.

[0047] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
