Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments of the present invention are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1 and fig. 2, fig. 1 is a top view of an embodiment of a horizontal continuous hybrid dryer of the present invention, and fig. 2 is a front view of the embodiment of the horizontal continuous hybrid dryer of the present invention. The horizontal continuous hybrid dryer 100 of the present invention has a biaxial structure, and includes: a housing 101, a first stirring system 102, a second stirring system 103, and a transmission system 104.
The shell 101 is a heart-shaped structure with a lower end and a double-circle upper end, the design of the heart-shaped structure can prevent the bottom of the material shell 101 from being stacked, and when the material input into the shell 101 is plastic, the plastic can be prevented from being stacked at the bottom of the shell 101 to form a shell. The outer part of the shell 101 is also provided with a jacket, and the jacket is filled with a heating medium as a first heat source in the drying process of the horizontal continuous hybrid dryer of the invention. The bottom of the housing 101 is mounted to a saddle 1014 for supporting the weight of the horizontal continuous hybrid dryer of the present invention.
An end cap 1011 is provided at each end of the housing 101, and a vacuum chamber 1012 and a packing seal 1013 are provided inside the end caps 1011. When the horizontal continuous hybrid dryer of the invention operates, firstly, the interior of the shell 10 needs to be vacuumized, and the vacuum can be realized by vacuumizing the vacuum air chamber 1012 inside the end cover 1011, because the vacuum air chamber 1012 is smaller, the vacuumizing effect is better, and the internal pressure in the shell 101 is higher than the internal pressure in the vacuum air chamber 1012, the gas in the shell 101 has certain internal leakage to the vacuum air chamber 1012, thereby further improving the vacuum degree in the shell 101; meanwhile, the double vacuum sealing structure can make the vacuum sealing condition in the shell 101 better.
The first stirring system 102 is disposed at one side in the housing 101, and the first stirring system 102 includes a feeding shaft 1021, a feeding scraper 1022, at least one blade 1023, and at least one rake tooth 1024. A feed shaft 1021 is attached to the housing 101, paddles 1023 and tines 1024 are provided on the feed shaft 1021, and a feed scraper 1022 is provided at one end of the feed shaft 1021. The feeding shaft 1021 is a mixed stirring shaft, and the rake teeth 1024 can be arranged on the feeding shaft 1021 according to actual use conditions.
The second stirring system 103 is disposed at another side of the housing 101, and the second stirring system 103 includes a discharging shaft 1031, a discharging scraper 1032, at least one blade 1023 and at least one rake 1024. The discharging shaft 1031 is connected to the housing 101, the paddle 1023 and the rake teeth 1024 are arranged on the discharging shaft 1031, and the discharging scraper 1032 is arranged at one end of the discharging shaft 1031. The discharging shaft 1031 is a mixing type stirring shaft, and the rake teeth 1024 can be arranged on the discharging shaft 1031 according to actual use conditions.
The harrow teeth 1024 and the blades 1023 of the invention are also provided with non-metal scrapers 1025 which can prevent the equipment from being damaged by the friction of rigid metal; meanwhile, the non-metal scraper 1025 has certain elasticity, when the non-metal scraper 1025 is tightly contacted with the shell 101, the non-metal scraper 1025 has a strong cleaning effect on the inner wall of the shell 101, and the influence of long-time accumulation of materials into shells on the heat transfer effect of the horizontal continuous mixing type drying machine can be prevented.
Preferably, the feeding shaft 1021, the discharging shaft 1031, the blades 1023 and the rake teeth 1024 are hollow and filled with a heating medium, so as to serve as a second heat source in the drying process of the horizontal continuous hybrid dryer of the present invention. It should be noted that the heating mediums filled in the jacket of the housing 101, the feeding shaft 1021, the discharging shaft 1031, the blades 1023 and the rake teeth 1024 may be the same or different, and the present invention is not limited to the type and the form of the heating mediums, as long as the heating mediums having the heating effect can be used in the horizontal continuous mixing dryer of the present invention.
The feed inlet 105 is arranged at the top of the shell 101 and close to the feed shaft 1021; the discharging hole 106 is disposed at the bottom of the housing 101 and near the discharging shaft 1031.
And the transmission system 104 is connected with the first stirring system 102 and the second stirring system 103 and is used for providing stirring power for the first stirring system 102 and the second stirring system 103. The driving end of the transmission system 104 comprises a large chain wheel 1041, a small chain wheel motor and a bearing 1042; the inlet 105 and outlet 106 are remote from the active end of the drive train 104.
The horizontal continuous mixing type dryer of the invention adopts a U-shaped structure for feeding, and can prolong the retention time of materials under the condition of meeting the deformation deflection of the feeding shaft 1021 and the discharging shaft 1031, so that the materials are fully dried.
In practical operation, the horizontal continuous hybrid dryer firstly needs to be vacuumized. After the feeding shaft 1021 and the discharging shaft 1031 start to stir, materials are fed from the feeding hole 105, the feeding scraper 1022 can prevent the materials from stopping on the end cover 1011 at one end of the shell 101, under the stirring action of the rake teeth 1024 at the front end of the feeding shaft 1021, the materials gradually enter the blade area, the directional non-metal scraper 1025 is distributed on the blade to push the materials to advance, the materials are fully preheated in the blade area, when the materials rotate to the rake teeth 1024 at the rear end of the feeding shaft 1021 along with the rake teeth 1024, the materials enter the discharging shaft 1031 side to be dried for the second time under the action of the discharging scraper 1032, and the materials continue to reach the discharging hole 106 along with the rotation of the discharging shaft 1031, so that a U-shaped stroke of the materials is formed. The materials are preheated along with the jacket heating and the feeding shaft 1021 and the discharging shaft 1031 in the U-shaped stroke, and finally reach the drying requirement of the degradable plastics in the drying process and are discharged from the discharging hole 106. Industrial practice proves that the horizontal continuous mixing type dryer has good vacuum degree effect, the feeding shaft 1021, the discharging shaft 1031, the blades 1023 and the rake teeth 1024 have very good stirring and drying effects on materials, and the purpose of large-treatment-capacity continuous feeding can be realized.
The embodiments of the present invention have been described in detail, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
