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. 1-4B, the present invention provides a charging device for a pyrolysis gasifier, which is used for charging a pyrolysis gasifier for processing solid waste, so as to replace a conventional garbage hanging charging manner, thereby not only realizing the charging of a plurality of pyrolysis gasifiers sharing a material conveyor belt, but also realizing the transmission and charging of materials with high viscosity and resistance, and reducing the phenomena of adhesion and blocking. The feeding device of the cracking gasification furnace comprises a material conveying belt 10 and at least one set of material guide device 20.
The material conveyer belt 10 is installed at one side of the pyrolysis gasifier 300 and used for conveying the material to be pyrolyzed.
The material transfer device 20 is used for transferring and transferring the material on the material conveying belt 10, so that the material is transferred into the feed hopper 310 of the pyrolysis gasifier 300. The number of the material guider 20 is different depending on the number of the pyrolysis gasifier 300. For a cracking system comprising a plurality of cracking gasifiers 300, the number of the material transfer devices 20 is the same as the number of the cracking gasifiers 300, so that the material transfer devices 20 correspondingly charge each cracking gasifier 300. Specifically, the material guiding device 20 includes a material guiding mechanism 21, a rotating mechanism 22, and a first driving mechanism 23.
As shown in fig. 5, the material guide mechanism 21 has a predetermined length, and includes a frame 211 and a rotating member 212. Wherein the frame 211 has a long rod shape and a predetermined length. The rotating member 212 is disposed on the frame 211 and rotates along a circular path. Optionally, in this embodiment, the rotating member 212 is a conveying belt. In other embodiments, the rotating member 212 may be other rotating bodies, for example, the rotating member 212 is a rotary rolling brush.
The material guiding device 20 further includes a second driving mechanism and a transmission mechanism 24, the second driving mechanism is connected to the transmission mechanism 24 and drives the transmission mechanism 24, and the transmission mechanism 24 is connected to the material guiding mechanism 21 and drives the rotating member 212 of the material guiding mechanism 21 to rotate. In other words, the second driving mechanism drives the rotating member 212 of the material guiding mechanism 21 to rotate circularly through the transmission mechanism 24. Optionally, the second drive mechanism is a motor.
One end of the frame 211 of the material guiding mechanism 21 is connected to the rotating mechanism 22 so that the material guiding mechanism 21 is operable to rotate about a fixed axis with the rotating mechanism 22 as a fulcrum.
The first driving mechanism 23 is connected to the material guiding mechanism 21, so that the first driving mechanism 23 drives the material guiding mechanism 21 to rotate around the rotating mechanism 22 as a fulcrum, and the material guiding mechanism 21 is switched between two positions. In the first position, as shown in fig. 4A, the material guiding mechanism 21 is parallel to the material conveying belt 10, and the material guiding mechanism 21 is located at one side of the conveying belt 10, which is the non-feeding state. In the second position, as shown in fig. 4B, in the feeding state, the material guiding mechanism 21 and the material conveying belt 10 intersect to form a predetermined angle, and when the material moving along with the material conveying belt 10 reaches the position of the material guiding mechanism 21, the rotating member 212 of the material guiding mechanism 21 turns and guides the material into the feeding hopper 310 of the pyrolysis gasifier 300.
Optionally, in this embodiment, the first driving mechanism 23 is an electro-hydraulic push rod, one end of the first driving mechanism 23 is connected to the frame 211 of the material guiding mechanism 21, and the first driving mechanism 23 cooperates with the rotating mechanism 22 to control the material guiding mechanism 21 to rotate within a predetermined range. In other embodiments, the first driving mechanism 23 may be another driving mechanism capable of driving the material guiding mechanism 21 to rotate; for example, the first driving mechanism 23 is a cylinder; for another example, the first driving mechanism 23 is a motor, and in practical applications, a driving motor may be directly disposed on the frame 211 of the material guiding mechanism 21 instead of the electro-hydraulic push rod, so as to rotate the rotating member 212 of the material guiding mechanism 21.
The material guiding device 20 further comprises a plowing plate 25, and the plowing plate 25 is fixed at the bottom of the frame 211 of the material guiding mechanism 21 and attached to the material conveying belt 10. The plough plate 25 can be effectively attached to the material conveying belt 10, so that the material guiding mechanism 21 and the material conveying belt 10 are in contact or have a reduced gap, and the material on the material conveying belt 10 can be guided into the pyrolysis gasification furnace 300.
The material guiding device 20 further includes a material supporting mechanism 26, and the material supporting mechanism 26 is disposed at the bottom of the material conveying belt 10 and supports the material conveying belt 10, so that the material conveying belt 10 and the plough plate 25 are attached. The material supporting mechanism 26 can make the material conveying belt 10 and the plough material plate 25 further tightly fit, so that the material is conveniently led in. The material plowing plate 26 and the material supporting mechanism are arranged to facilitate the transmission of materials, so that the material conveying belt 10 is not only limited to a conveying belt, but also can be made of other materials; moreover, the material supporting mechanism 26 can ensure that the material conveying belt 10 is not limited by angles, and the application range is wider
The material guiding device 20 further comprises a fixing bracket 27 and a mounting support 28, and the mounting support 28 and the rotating mechanism 22 are both arranged on the fixing bracket 27. The holding mechanism 26 is also disposed on the fixing bracket 27. One end of the first driving mechanism 23 is mounted on the mounting support 28, and the other end of the first driving mechanism 23 is connected to the frame 211 of the material guiding mechanism 21.
When the pyrolysis gasifier feeding device operates, taking one set of the material guiding device 20 as an example to feed one pyrolysis gasifier 300, when the pyrolysis gasifier feeding device is not in a feeding state, the material guiding mechanism 21 of the material guiding device 20 is in a first position, as shown in fig. 4A, the material guiding mechanism 21 is parallel to the material conveying belt 10. When the cracking gasifier 300 needs to be fed, the transmission mechanism 24 of the material guiding device 20 is firstly opened and the rotating member 212 of the material guiding mechanism 21 is driven to rotate under the action of the second driving motor, which is the direction of the rotation of the rotating member 212 as shown by the arrow in fig. 1 and 4B. The material guiding mechanism 21 is then controlled by the first driving mechanism 23 to rotate from the first position to the second position. After the material guiding mechanism 21 rotates to the second position, as shown in fig. 4B, the material guiding mechanism 21 and the material conveying belt 10 intersect to form an angle, and the material guiding device 20 is completely in place. Then, the material conveying belt 10 starts to operate to convey materials, the materials are fed into the material conveying belt 10, and the materials move towards the pyrolysis gasification furnace 300 to be fed along with the material conveying belt 10. When the material is conveyed to the position of the material guiding mechanism 21, the material contacts the rotating member 212 of the material guiding mechanism 21, and the rotating member 212 is in rotating operation. Since the material moving along the material conveying belt 10 has a partial velocity in the moving direction of the rotary member 212, the material is diverted in the direction of the linear arrow shown in fig. 1 and 4B and enters the feeding hopper 310 of the pyrolysis gasifier 300. In this process, the rotating member 212 drives the material to move in a direction-changing manner while rotating, so as to guide the material into the pyrolysis gasifier 300 in a direction-changing manner.
It can be understood that, because the resistance to the transportation of the materials such as the household garbage, the stored garbage, the mixed garbage, and the like is large, and the fluency is poor, and when the material guiding mechanism 21 is located at the second position for guiding the materials, because the material guiding mechanism 21 and the material conveying belt 10 are crossed to form a predetermined angle, the moving direction of the rotating member 212 of the material guiding mechanism 21 along the rack 211 is consistent with the speed dividing direction of the material conveying belt 10, and such an angle design is more favorable for the rotating member 212 of the material guiding mechanism 21 to guide the materials into the pyrolysis gasifier 300, and is favorable for driving the materials to flow.
In order to further promote the material flowing by the rotating member 212 of the material guiding mechanism 21, when the rotating member 212 is a conveyor belt, the surface of the rotating member 212 is further provided with patterns or protrusions to increase the friction between the material and the rotating member 212. Optionally, a baffle is further disposed on the rotating member 212 to enhance the guiding effect of the rotating member 212 on the material.
When the feeding amount of the pyrolysis gasifier 300 meets the requirement, stopping feeding the material to the material conveyer belt 10, after all the materials on the material conveyer belt 10 are introduced into the corresponding feed hopper 310 of the pyrolysis gasifier 300, starting the first driving mechanism 23 of the material guiding device 20 again to rotate the material guiding mechanism 21 from the second position to the first position, that is, rotating the material guiding mechanism 21 to a position parallel to the material conveyer belt 10, thereby completing the feeding process of the pyrolysis gasifier 300.
Alternatively, in another embodiment, the material guiding mechanism 21 is directly a plough plate or other rotating body with similar principle. One end of a plough plate as the material guiding mechanism 21 is directly connected with the rotating mechanism 22 and is operable to rotate around a fixed shaft with the rotating mechanism 22 as a fulcrum, so that the material guiding mechanism 21 is switched between the first position and the second position under the driving of the first driving motor 23. The scheme of using a plough plate as the material guiding mechanism 21 can omit a second driving motor and a transmission mechanism 24, and is suitable for conveying materials with low viscosity and resistance.
When the number of the pyrolysis gasifier 300 is plural, the number of the material guider 20 is plural sets accordingly. All the material guiding devices 20 are distributed at intervals along the material conveying belt 10 and respectively guide the materials into the plurality of pyrolysis gasifiers 300 in one-to-one correspondence. For example, as shown in fig. 1, the number of the pyrolysis gasifier 300 is three, and the three pyrolysis gasifiers 300 are distributed side by side, so the number of the material guiding and transporting devices 20 is also three, the material conveyer belt 10 is installed on the same side of the three pyrolysis gasifiers 300, and the three material guiding and transporting devices 20 are arranged at intervals along the material conveyer belt 10. Each material handling device 20 can be operated individually to charge one pyrolysis gasifier 300. All the material conveyors 20 share one material conveyor belt 10, and all the material conveyors 20 load the cracking gasifier 300 in the same operation. After the first set of material guiding and transporting device 20 is operated to complete the loading of the first pyrolysis gasifier 300, the other two material guiding and transporting devices 20 are respectively operated repeatedly according to the above description, so as to complete the loading of the other two pyrolysis gasifiers 300.
According to another aspect of the present invention, the present invention further provides a feeding method of the cracking gasifier feeding device, comprising the following steps:
starting the first driving mechanism 23 to rotate the material guiding mechanism 21 from the first position to the second position;
starting the material conveying belt 10 to operate to convey the material, and after the material reaches the position of the material guide mechanism 21, turning the material by the material guide mechanism 21 and guiding the material into the pyrolysis gasification furnace 300;
when the feeding amount meets the requirement, the feeding is stopped to the material conveying belt 10, and after the materials on the material conveying belt 10 are all introduced into the feeding hopper 310 of the pyrolysis gasifier 300, the first driving mechanism 23 is started to make the material guiding mechanism 21 return to the first position from the second position. Through the above steps, the pyrolysis gasifier 300 may be continuously fed.
In the structure in which the material guiding mechanism 21 is provided with the rotating member 212 on the frame 211, before the first driving mechanism 23 is started, the second driving mechanism and the transmission mechanism 24 are started to drive the rotating member 212 of the material guiding mechanism 21 to rotate circularly.
The cracking gasification furnace feeding device and the feeding method thereof provided by the invention have the following advantages: multiple sets of material guiding devices 20 can share one material conveying belt and feed multiple pyrolysis gasifiers 300, so that the material conveying and feeding cost of the pyrolysis gasifiers can be greatly saved. And secondly, the traditional garbage hoisting and feeding mode can be replaced, the structure is simple, the height of a traditional feeding workshop can be greatly reduced, and the feeding equipment cost and the civil engineering cost are saved. Thirdly, the rotating part of the material guide mechanism is adopted to guide the materials, so that the conveying device is beneficial to conveying the materials with higher resistance and viscosity, is more suitable for treating the materials with higher humidity, such as household garbage, stock garbage, mixed garbage and the like, and reduces the phenomena of adhesion and blockage during feeding.
