Description

Technical Field

[0001] This application relates to the technical field of rotary kiln incineration devices, and in particular to a high-efficiency rotary kiln incineration device. Background Technology

[0002] Rotary kiln incineration units occupy a crucial position in modern industry and environmental protection. With increasingly stringent requirements for resource utilization efficiency and environmental protection, the need for performance optimization of rotary kiln incineration units is becoming increasingly prominent.

[0003] Traditional rotary kiln incineration units often suffer from numerous shortcomings, resulting in low combustion efficiency. For example, materials are typically not adequately pre-treated before entering the incineration unit. In many cases, the materials enter the feeding system directly in a raw, mixed state of lumps, granules, etc. For instance, when processing industrial waste or biomass fuel, these materials may contain various components and sizes. Some material lumps may be too large, while others may agglomerate together to form large clusters. Such untreated, large-sized materials are difficult to heat quickly and fully within the rotary kiln, and the interior of large material lumps may remain at a low temperature for a long time, failing to reach the ideal combustion temperature, thus causing incomplete combustion. In addition, the problem of material agglomeration leads to uneven distribution of materials within the rotary kiln, affecting the stability and efficiency of combustion.

[0004] Therefore, a high-efficiency rotary kiln incineration device is invented to solve the problems mentioned in the background art. Utility Model Content

[0005] In order to improve the pretreatment effect of incineration materials and the combustion efficiency of rotary kiln incineration device, this application provides a high-efficiency rotary kiln incineration device.

[0006] This application provides a high-efficiency rotary kiln incineration device, which adopts the following technical solution: It includes a fixed frame, wherein a guide groove is provided on the fixed frame, and a vertically movable feed hopper is slidably connected in the guide groove. A separation inner cylinder is connected to one side of the feed hopper, and a movable separation outer cylinder is provided on the outside of the separation inner cylinder. The separation inner and outer cylinders have overlapping material discharge holes. When the separation outer and inner cylinders move relative to each other, the overlapping portion of the material discharge holes changes. A rotatable stirring rod is provided inside the feed hopper, and several cutting blades are provided on the stirring rod to cut the material. The cutting blades are spiral-shaped. When the stirring rod drives the cutting blades to rotate, the cutting blades push the material to move. A rotatable rotating cylinder is provided on the fixed frame, and the separation outer cylinder is located inside the rotating cylinder.

[0007] Optionally, the stirring rod is provided with limiting mechanisms at both ends to limit its position. The limiting mechanism includes a fixed base, a square groove in the vertical direction is provided in the fixed base, a sliding block is provided in the square groove, the stirring rod passes through the sliding block and is rotatably connected to the sliding block, and a first compression spring is provided at both the upper and lower ends of the sliding block, the other end of the first compression spring is fixedly connected to the fixed base.

[0008] Optionally, the fixed frame is provided with a drive mechanism that can drive the stirring rod to move up and down. The drive mechanism includes a first motor, which is fixed on the fixed frame. A push rod is provided at the output end of the first motor. Counterweights are provided at both ends of the stirring rod. A transmission plate is provided at the end of the stirring rod near the first motor. The push rod can contact and connect with the transmission plate. When the first motor rotates, it drives the push rod to push the transmission plate to rotate.

[0009] Optionally, a second motor is provided on the fixed frame, an active friction wheel is provided at the output end of the second motor, a driven friction wheel is provided on the rotating cylinder that can be driven by friction with the active friction wheel, and a spiral guide bar is provided inside the rotating cylinder.

[0010] Optionally, the rotating cylinder has a discharge port on the side away from the feed hopper, and the outer separating cylinder has a threaded hole at one end of the discharge port. The inner separating cylinder is threadedly connected to the outer separating cylinder, the outer separating cylinder is equipped with a rotating handle, and the inner separating cylinder is rotatably connected to the stirring rod.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. By setting up a feed hopper that can move up and down, a stirring rod with cutting blades, and movable inner and outer separation cylinders, the material can be fully pre-treated. The cutting blades can chop large-sized materials and push the materials to move, preventing uneven heating and incomplete combustion in the rotary kiln due to excessive material size or agglomeration, thereby improving combustion efficiency.

[0013] 2. The first motor, push rod and transmission plate and counterweight on the stirring rod in the drive mechanism work together to enable the stirring rod to move up and down, which further enhances the stirring and cutting effect on the material in the feed hopper, making the material mix more even and the pretreatment more thorough. At the same time, it causes the material in the feed hopper and the rotating inner cylinder to vibrate up and down to separate the cut granular material.

[0014] 3. The design of the threaded hole, rotating handle, and discharge port on the outer cylinder facilitates the relative movement of the inner and outer cylinders. The overlapping part of the discharge hole can be adjusted as needed, and it also facilitates the discharge of processed materials. Attached Figure Description

Detailed Implementation

[0021] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0022] Reference Figure 2 , Figure 4 , Figure 5 One embodiment shown is as follows: This high-efficiency rotary kiln combustion device includes a fixed frame 1, which serves as the support structure for the entire device. A guide groove 2 is provided on the fixed frame 1. A feed hopper 3 that can move up and down is slidably connected in the guide groove 2. A separation inner cylinder 4 is fixedly connected to one side of the feed hopper 3. A separation outer cylinder 5 is movably connected to the outside of the separation inner cylinder 4. The separation inner cylinder 4 and the separation outer cylinder 5 can move relative to each other. The separation inner cylinder 4 and the separation outer cylinder 5 are provided with overlapping material discharge holes 6. By changing the relative position of the separation outer cylinder 5 and the separation inner cylinder 4, the overlapping part of the material discharge holes 6 can be changed, thereby controlling the flow rate of the material and the size of the material flowing out.

[0023] A rotatable stirring rod 7 is installed inside the feed hopper 3. Multiple cutting blades 8 are fixedly welded on the stirring rod 7. The cutting blades 8 are spiral-shaped. When the stirring rod 7 rotates, the cutting blades 8 can not only cut the material, but also push the material to move, preventing the material from accumulating in the feed hopper 3. In addition, a rotatable rotating cylinder 9 is rotatably connected to the fixed frame 1, and the separation outer cylinder 5 is located inside the rotating cylinder 9.

[0024] Implementation principle: By setting up a vertically movable feed hopper 3, a stirring rod 7 with cutting blades 8, and movable inner and outer separation cylinders 4 and 5, the material can be fully pre-treated. The cutting blades 8 can chop large-sized materials and push them to move, preventing uneven heating and incomplete combustion in the rotary kiln due to excessive material size or agglomeration, thereby improving combustion efficiency. The rotation of the stirring rod 7 drives the spiral cutting blades 8 to cut and stir the material. The spiral shape of the cutting blades 8 causes the material to be subjected to an axial thrust while being cut, thereby realizing the movement and mixing of the material in the feed hopper 3.

[0025] Reference Figure 1 , Figure 2 One embodiment shown is as follows: Both ends of the stirring rod 7 are respectively provided with limiting mechanisms 10 for limiting the stirring rod 7. The limiting mechanism 10 includes a fixed base 11, and a square groove 12 in the vertical direction is opened in the fixed base 11. A sliding block 13 is slidably connected in the square groove 12. The stirring rod 7 passes through the sliding block 13 and is rotatably connected to the sliding block 13. The upper and lower ends of the sliding block 13 are respectively fixedly connected with a first compression spring 14. The other end of the first compression spring 14 is fixedly connected to the fixed base 11. This limiting mechanism 10 can effectively limit and buffer the stirring rod 7 during its up-and-down movement and rotation, ensuring the stability of the stirring rod 7's movement, and also helping to extend the service life of the device.

[0026] The fixed frame 1 is equipped with a drive mechanism 15 that can drive the stirring rod 7 to move up and down. The drive mechanism 15 includes a first motor 16, which is fixed on the fixed frame 1. An L-shaped push rod 17 is fixedly connected to the output end of the first motor 16. Counterweights 18 are fixedly connected to both ends of the stirring rod 7. A transmission plate 19 is fixedly connected to one end of the stirring rod 7 near the first motor 16. The push rod 17 can contact and connect with the transmission plate 19. When the first motor 16 rotates, it drives the push rod 17 to push the transmission plate 19 to rotate.

[0027] Implementation principle: The first motor 16 serves as the power source for the up-and-down movement and rotation of the stirring rod 7. When the push rod 17 at the output end of the first motor 16 rotates, it contacts the transmission plate 19 on the stirring rod 7. Due to the distribution of counterweights 18 at both ends of the stirring rod 7, the stirring rod 7 will rotate around its axis under the push of the push rod 17. At the same time, due to the thrust on the transmission plate 19 and the action of the counterweights 18, the stirring rod 7 will move up and down under the restriction of the limiting mechanism 10. The sliding block 13 in the limiting mechanism 10 slides in the square groove 12. The first compression springs 14 at both ends provide buffering and restoring force for the up-and-down movement of the stirring rod 7, ensuring that the stirring rod 7 moves stably within a certain range.

[0028] Reference Figure 1 One embodiment shown is as follows: a second motor 20 is fixedly connected to the fixed frame 1, an active friction wheel 21 is fixedly connected to the output end of the second motor 20, a driven friction wheel 22 that can be frictionally driven with the active friction wheel 21 is fixedly connected to the rotating cylinder 9, and a spiral guide bar 23 is fixedly connected inside the rotating cylinder 9.

[0029] Implementation principle: When the material enters the rotating drum 9, it can be heated and burned inside the rotating drum 9, thereby improving the combustion efficiency of the material in the rotary kiln. The second motor 20 is started, which drives the active friction wheel 21 to rotate. The active friction wheel 21 drives the driven friction wheel 22 to rotate through friction, thereby causing the rotating drum 9 to start rotating. The spiral guide bar 23 inside the rotating drum 9 rotates together with the rotating drum 9. After contacting the material, it uses the characteristics of the spiral structure to generate a thrust on the material along the axis of the rotating drum 9 towards the discharge port 24. Under the action of this thrust, the material moves towards the discharge port 24 along the path of the spiral guide bar 23 inside the rotating drum 9. During the movement, the material continues to tumble, further ensuring the uniformity of the material.

[0030] Reference Figure 1 One embodiment shown is as follows: a discharge port 24 is provided on the side of the rotating cylinder 9 away from the feed hopper 3, a threaded hole 25 is provided at one end of the discharge port 24 on the outer separating cylinder 5, the inner separating cylinder 4 is threadedly connected to the outer separating cylinder 5, a rotating handle 26 is fixedly connected to the outer separating cylinder 5, and the inner separating cylinder 4 is rotatably connected to the stirring rod 7.

[0031] Implementation principle: The material enters the inner cylinder 4 through the discharge hole 6 and enters the rotating cylinder 9. By rotating the rotating handle 26 on the outer cylinder 5, since the outer cylinder 5 and the inner cylinder 4 are connected by threads, the outer cylinder 5 rotates relative to the inner cylinder 4, changing the overlapping part of the discharge holes 6 on the two, thereby adjusting the size and flow rate of the discharged material.

[0032] The working principle of this device is as follows: When this high-efficiency rotary kiln incineration device is working, the material first enters the feed hopper 3. Inside the feed hopper 3, the stirring rod 7 moves up and down and rotates under the coordinated action of the first motor 16, push rod 17, transmission plate 19 and counterweight 18. Its spiral cutting blade 8 cuts and stirs the material, so that the material is fully mixed and large-sized materials are shredded. The pre-treated material moves towards the separation inner cylinder 4 under the push of the stirring rod 7.

[0033] By operating the rotating lever 26 on the outer separating cylinder 5, the overlap of the material discharge holes 6 on the inner separating cylinder 4 and the outer separating cylinder 5 is adjusted, thereby controlling the size and flow rate of the material entering the rotating cylinder 9. After the material enters the rotating cylinder 9, the second motor 20 drives the rotating cylinder 9 to rotate. The spiral guide strip 23 inside the rotating cylinder 9 pushes the material towards the discharge port 24. The material can be heated and burned inside the rotating cylinder 9, thereby improving the combustion efficiency of the material in the rotary kiln.

[0034] The working principle of this device has been explained through the above embodiments. These embodiments merely illustrate several implementation methods of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
