Detailed Description
The following description of the embodiments of the present invention will be made in detail and with reference to the accompanying drawings, wherein it is apparent that the embodiments described herein are only some, but not all embodiments of the invention. All other embodiments, which can be made by a person skilled in the art based on the embodiments of the invention without any inventive effort, are intended to fall within the scope of the invention.
Referring to fig. 1 and 2, fig. 1 is a top view of an embodiment of a horizontal continuous mixing dryer according to the present invention, and fig. 2 is a front view of an embodiment of a horizontal continuous mixing dryer according to the present invention. The horizontal continuous hybrid dryer 100 of the present invention has a biaxial structure, and includes: a housing 101, a first agitation system 102, a second agitation system 103, and a transmission system 104.
The shell 101 is a heart-shaped structure with two upper ends and a big circle at the lower end, the heart-shaped structure can prevent the bottom of the shell 101 from being piled up, and when the material input into the shell 101 is plastic, the plastic can be prevented from being piled up to form a shell at the bottom of the shell 101. The outside of the housing 101 is also provided with a jacket, in which a heating medium is filled as a first heat source in the drying process of the horizontal continuous hybrid dryer of the present invention. The bottom of the housing 101 is mounted to a saddle 1014 for supporting the weight of the horizontal continuous mixing dryer of the present invention.
An end cover 1011 is provided at each end of the housing 101, a vacuum chamber 1012 is provided inside the end cover 1011, and a packing seal 1013 is provided inside the end cover. When the horizontal continuous mixed dryer is operated, firstly, the vacuum pumping operation is needed to be carried out in the shell 10, and the vacuum pumping operation can be realized by pumping the vacuum air chamber 1012 in the end cover 1011, and because the vacuum air chamber 1012 is smaller, the vacuum pumping effect is better, the internal pressure in the shell 101 is higher than the internal pressure in the vacuum air chamber 1012, so that the gas in the shell 101 has certain internal leakage to the vacuum air chamber 1012, and the vacuum degree in the shell 101 is further improved; meanwhile, the double vacuum sealing structure can enable the vacuum sealing condition in the shell 101 to be better.
The first stirring system 102 is disposed on 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 1024. The feeding shaft 1021 is connected to the housing 101, the paddle 1023 and the rake 1024 are provided on the feeding shaft 1021, and the feeding scraper 1022 is provided at one end of the feeding shaft 1021. The feeding shaft 1021 is a hybrid 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 on the other side in 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 1024 are disposed on the discharging shaft 1031, and the discharging scraper 1032 is disposed at one end of the discharging shaft 1031. The discharging shaft 1031 is a mixed stirring shaft, and the rake teeth 1024 can be disposed on the discharging shaft 1031 according to actual use conditions.
The rake teeth 1024 and the blades 1023 are also provided with non-metal scraping plates 1025, and the non-metal scraping plates can prevent the damage of the equipment caused by friction of rigid metal; meanwhile, the nonmetal scraping plate 1025 also has certain elasticity, when the nonmetal scraping plate 1025 is tightly contacted with the shell 101, the nonmetal scraping plate 1025 has strong cleaning effect on the inner wall of the shell 101, and can prevent materials from accumulating into shells for a long time to influence the heat transfer effect of the horizontal continuous mixing dryer.
Preferably, the interiors of the feed shaft 1021, the discharge shaft 1031, the blades 1023 and the rake teeth 1024 are hollow structures and filled with a heating medium, so that the hollow structures are used as a second heat source in the drying process of the horizontal continuous hybrid dryer of the invention. It should be noted that the jacket of the housing 101, the feeding shaft 1021, the discharging shaft 1031, the blades 1023, and the heating medium filled in the rake teeth 1024 may be the same or different, and the invention is not limited to the type and the shape of the heating medium, so long as the heating medium having a heating effect can be used in the horizontal continuous mixing dryer of the invention.
The feed port 105 is arranged at the top of the shell 101 and is close to the feed shaft 1021; the discharge port 106 is disposed at the bottom of the housing 101 and near the discharge 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 drive end of the drive system 104 includes a large sprocket 1041, a small sprocket motor, and a bearing 1042; the inlet 105 and outlet 106 are remote from the drive end of the drive train 104.
The horizontal continuous mixed dryer is in a U-shaped structure for feeding, and can prolong the retention time of materials and fully dry the materials under the condition of meeting the deformation deflection of a feeding shaft 1021 and a discharging shaft 1031.
In practical operation, the horizontal continuous mixed dryer of the invention needs to be vacuumized. After the feed shaft 1021 and the discharge shaft 1031 start stirring, the material is fed from the feed port 105, the feed scraper 1022 can prevent the material from staying 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 feed shaft 1021, the material gradually enters the blade area, the directional nonmetallic scraping plates 1025 distributed on the blades push the material to advance, the material is fully preheated in the blade area, and when the material rotates to the rake teeth 1024 at the rear end of the feed shaft 1021 along with the rake teeth 1024, the material enters the discharge shaft 1031 side for secondary drying under the action of the discharge scraper 1032, and continuously reaches the discharge port 106 along with the rotation of the discharge shaft 1031, so that the U-shaped travel of the material is formed. The material is preheated along with the jacket heating, the feeding shaft 1021 and the discharging shaft 1031 in the U-shaped travel, and finally reaches the drying requirement of the degradable plastic in the drying process, and is discharged from the discharging hole 106. Industrial practice proves that the horizontal continuous mixing dryer has good vacuum degree effect, the stirring and drying effects of the feeding shaft 1021, the discharging shaft 1031, the paddles 1023 and the rake teeth 1024 on materials are very good, and the purpose of continuous feeding with large treatment capacity can be realized.
The embodiments of the present invention have been described in detail above, 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 to these embodiments without departing from the principles and spirit of the invention, and yet fall within the scope of the invention.
