Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides a lifting blade that whisker drying-machine used, including a stoving section of

thick bamboo

1, 2 transmissions of drive wheel are connected are passed through to the one end of a stoving section of thick bamboo 1, the internal surface feed end of a stoving section of thick bamboo 1 is provided with spiral delivery sheet 3, be provided with rice style of calligraphy lifting blade 4 in the middle of the inside of a stoving section of thick bamboo 1, a stoving section of thick bamboo 1 passes through connecting rod 5 fixed connection with rice style of calligraphy lifting blade 4, connecting rod 5 connects the other end of rice style of calligraphy lifting blade 4 and is connected with second lifting blade 7 through 6 rotations of gearbox, second lifting blade 7 is located the discharge end of a stoving section of thick bamboo 1.

Specifically, the baffle that rice style of calligraphy lifting blade 4 extends is not in feed table 3 direct contact, but both clearances are less, and the baffle that second lifting blade 7 extends also does not contact with the internal surface of drying cylinder 1, but both clearances are less.

Specifically, the annular surface of the gear box 6 is fixedly connected with the inner surface of the drying drum 1 through a fixing rod.

Specifically, the gearbox 6 is a speed reducer, so that the rotating speed of the second material raising plate 7 is smaller than that of the material raising plate 4 shaped like a Chinese character 'mi'.

Specifically, the internal surface of feed plate 3 at a section of thick bamboo 1 of drying is the helical structure who encircles, and spiral pivoted feed plate 3 is sent the material to the upper end of rice style of calligraphy lifting blade 4 in this embodiment and is raised the material.

Specifically, the number of the material plates on the second material raising plate 7 is several, in the rear section of the dryer, namely, the speed reduction drying stage in the embodiment, the drying speed of the material mainly depends on the migration speed of moisture in the material, the moisture of the material is low and loose at the stage, a large amount of dust is inevitably generated by the strong material raising, the burden of the dust collection equipment is increased, and therefore the material plates can be properly arranged and thinned at the later speed reduction drying stage, particularly near the discharge end.

The working principle and the using process of the utility model are as follows: install central rice style of calligraphy lifting blade additional in the middle of the drying-machine, the material that gets into the drying-machine is at first taken to the take-up altitude by the lifting blade, then throw the liftout, the material after throwing down gets into in the middle part rice style of calligraphy lifting blade, the material is thrown lower floor's rice style of calligraphy lifting blade once more from upper strata rice style of calligraphy lifting blade to the material is thrown to the formation layer upon layer, the material is rain form material curtain in the stoving cross-section, hot hollow existence in the drying-machine has been avoided, play the direction, flow equalize and hinder the material effect. The materials are continuously thrown in the rice-shaped lifting plate, so that the retention time of the materials in the rice-shaped lifting plate is prolonged, the opportunity of exchanging the materials with hot air is increased, and the heat exchange efficiency in the dryer is improved; meanwhile, as the materials are repeatedly thrown in the rice lifting plate, a certain crushing effect is achieved, and the drying effect is greatly improved. It is advantageous that the lifter plates are arranged appropriately closely. In the rear section of the dryer, namely the speed reduction drying stage, the drying speed of the material is mainly determined by the migration speed of moisture in the material, the moisture of the material is low and loose in the stage, and a large amount of dust is inevitably generated by strong material raising, so that the burden of dust collection equipment is increased, and the material raising plates can be properly arranged and arranged sparsely in the rear speed reduction drying stage, particularly near the discharge end.
