Detailed Description
the following description is only for the purpose of disclosing the invention so as to enable a person skilled in the art to practice the invention. The embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other arrangements without departing from the spirit and scope of the invention.
As shown in fig. 1-3, the present invention provides a shaftless spiral air-locking feeding device for a pyrolysis gasifier, which can continuously, uniformly and smoothly feed the pyrolysis gasifier, and can prevent air from entering the furnace body of the pyrolysis gasifier during the feeding process, so as to achieve the air-locking effect. Specifically, the shaftless spiral air locking feeding device of the pyrolysis gasifier comprises a shell 10, at least two shaftless spiral bodies 20 and a driving mechanism 30.
The casing 10 has a predetermined length and a cavity therein, and the casing 10 has an inlet port 101 and an outlet port 102. The feed port 101 is located at the top of the casing 10 and is communicated with a feed hopper 310 of the pyrolysis gasifier 300, and the discharge port 102 is located at one end of the casing 10 and is communicated with a furnace body 320 of the pyrolysis gasifier 300. The top of the casing 10 is provided with an access hole 103 for convenient access.
The shaftless spiral air locking feeding device of the pyrolysis gasifier further comprises a supporting platform 40, a supporting frame 51 and a supporting frame 52, wherein the supporting frame 51 is arranged on the supporting platform 40. The supporting frame 51 is fixed to the bottom of the casing 10 to support the casing 10, that is, the casing 10 is mounted on the supporting frame 51. The support bracket 52 is disposed at the top of the cabinet 10 to support the feed hopper 310.
The quantity of the shaftless spiral bodies 20 is multiple, and all the shaftless spiral bodies 20 are arranged in parallel in the cavity of the casing 10. The shaftless screw 20 has a predetermined length and is formed in a spiral shape having a plurality of integrally connected spiral blades.
The drive mechanism 30 is coupled to the shaftless screw 20 to drive the rotation of the shaftless screw 20. The number of the driving mechanisms 30 is also plural and is consistent with the number of the shaftless screws 20. The driving mechanisms 30 are connected with and drive the shaftless screw 20 to rotate in a one-to-one correspondence. Any two adjacent shaftless screws 20 rotate in opposite directions, that is, when one of the shaftless screws 20 rotates clockwise, the other adjacent shaftless screw 20 rotates counterclockwise.
The shaftless spiral air locking feeding device of the pyrolysis gasifier further comprises a supporting bearing 60, the supporting bearing 60 is installed in a bearing seat, and the driving mechanism 30 is connected with the supporting bearing 60 so as to drive the shaftless spiral body 20 through the supporting bearing 60. The number of the supporting bearings 60 is plural and is consistent with the number of the driving mechanisms 30, and the driving mechanisms 30 are connected with the supporting bearings 60 in a one-to-one correspondence to drive the respective different shaftless screws 20 respectively.
In the present embodiment, as shown in fig. 4A, the number of the shaftless screws 20 is two, and the two shaftless screws 20 rotate in opposite directions, i.e. the shaftless screw 20 on the left side of fig. 4A rotates clockwise, and the shaftless screw 20 on the right side of fig. 4A rotates counterclockwise, as shown by the arrow in fig. 4A, so that the material in the middle of the two shaftless screws 20 turns outward.
In another embodiment, as shown in fig. 4B, the number of the shaftless screws 20 is two, and the two shaftless screws 20 rotate oppositely, i.e. the shaftless screw 20 on the left side of fig. 4B rotates counterclockwise, and the shaftless screw 20 on the right side of fig. 4B rotates clockwise, as shown by the arrow in fig. 4B, so that the material in the middle of the two shaftless screws 20 turns inward.
When the shaftless spiral air locking feeding device of the pyrolysis gasification furnace operates, materials are conveyed into a feed hopper 310 of the pyrolysis gasification furnace 300 for temporary storage through a grab bucket or a conveyor in advance. The driving mechanism 30 is started, and the driving mechanism 30 drives the shaftless screw body 20 to rotate, so that the rotation directions of any two adjacent shaftless screw bodies 20 are opposite. The material buffered in the feeding hopper 310 gradually enters the cavity of the casing 10 under the self-gravity and the propelling action of the shaftless screw 20. The material entering the casing 10 from the feeding port 101 gradually enters the furnace body 320 of the pyrolysis gasifier 300 from the discharging port 102 under the propelling action of the shaftless spiral body 20.
it can be understood that, because the rotation directions of any two adjacent shaftless spiral bodies 20 are opposite, when the two adjacent shaftless spiral bodies 20 rotate in opposite directions, as shown by arrows in fig. 4A, during the rotation and propulsion of the material, the material falling to the middle of the two shaftless spiral bodies 20 is continuously turned outwards by the two shaftless spiral bodies 20, that is, the material is turned out from the middle of the two shaftless spiral bodies 20 to both sides. On the contrary, when two adjacent shaftless screws 20 rotate oppositely, as shown by the arrow in fig. 4B, the material falling to the middle of the two shaftless screws 20 is continuously turned inwards by the two shaftless screws 20, that is, the material is rolled into the middle of the two shaftless screws 20 from both sides of the two shaftless screws 20. Any two adjacent shaftless spiral bodies 20 in the plurality of shaftless spiral bodies 20 rotate reversely, and materials falling to the middle of the two shaftless spiral bodies 20 can turn outwards or inwards constantly in the rotating and propelling process of the materials, so that the materials can be effectively prevented from being wound and blocked. According to general engineering experience, relatively speaking, the two adjacent shaftless spiral bodies 20 rotate oppositely, so that the material between the two shaftless spiral bodies 20 is more easily prevented from being blocked and wound in an outwards turning mode, and the smooth transmission effect is realized.
In addition, because the pyrolysis gasifier 300 is continuously fed, the materials can play a role in isolating external air in the process of being pushed by the shaftless spiral body 20, and basically no air enters the pyrolysis gasifier 300, so that the air locking effect is realized.
further, the feeding method of the shaftless spiral air locking feeding device of the pyrolysis gasifier comprises the following steps:
conveying the material into a feed hopper 310 of a pyrolysis gasifier 300 through a grab bucket or a conveyor;
The shaftless screw bodies 20 are driven by the driving mechanism 30, so that the rotation directions of any two adjacent shaftless screw bodies 20 are opposite, and the material enters the shell 10 from the feed hopper 310 and gradually enters the pyrolysis gasification furnace 300 from the discharge port 102 under the self-gravity and the propelling action of the shaftless screw bodies 20. In practical application, the rotation speed of all the shaftless screws 20 can be set according to requirements, and the rotation speed of each shaftless screw 20 can be the same or different. According to practical experience, when the rotating speed and the rotating direction of two adjacent shaftless spiral bodies 20 are different, the material scattering and conveying can be realized, and the material winding and blocking can be effectively avoided.
In the prior art, a general cracking gasification furnace adopts grab bucket feeding, an opening at the top of the cracking gasification furnace needs to be opened in the feeding process so as to facilitate feeding, but when the furnace body is opened, external air can rapidly enter the cracking gasification furnace to destroy the anaerobic or anaerobic environment in the cracking gasification furnace. In the feeding method provided by the invention, the material and the shaftless spiral body 20 effectively isolate the feed inlet of the pyrolysis gasifier from the outside air, and the pyrolysis process is an anaerobic or anaerobic process. In addition, the invention adopts a shaftless spiral feeding mode, which not only can effectively realize continuous feeding of the pyrolysis gasification furnace as required, is beneficial to the material homogenizing and reaction process of the material in the pyrolysis gasification furnace, but also can effectively solve the problems of material winding on a rotating shaft and material blockage in the traditional shaft spiral feeding mode.
it will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention. The objects of the invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the examples, and the embodiments of the present invention may be subject to any changes or modifications without departing from the principles.
