Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste incinerator technology, specifically to a waste incinerator with a sludge drying spraying device. Background Technology
[0002] With the acceleration of urbanization, the production of domestic waste and sludge has increased dramatically. Traditional landfill methods can no longer meet environmental protection requirements. Waste incineration technology has been widely used due to its advantages of volume reduction, harmlessness and resource recovery. In the process of waste incineration, in order to facilitate the incineration of sludge, sludge is often sprayed into the interior of the waste incinerator through a sludge injection device.
[0003] In actual use, the injection device in the existing waste incinerator atomizes the sludge and continuously sprays it onto the flame in the middle of the furnace for combustion at high temperature. Since the sludge has a water content of more than 80%, continuous combustion will cause the flame temperature to drop, which will easily lead to incomplete combustion of the sludge, resulting in more combustion residues and a large amount of particulate dust.
[0004] Therefore, it is necessary to invent a waste incinerator with a sludge drying spraying device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a waste incinerator with a sludge drying and spraying device to solve the problem that prolonged continuous incineration in the technology leads to a decrease in flame temperature, which in turn easily results in incomplete combustion of sludge, a large amount of combustion residue, and the generation of a large amount of particulate dust.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a waste incinerator with a sludge drying spraying device, comprising multiple equipment boxes, wherein a spraying assembly is provided on the lower side of the equipment box, the spraying assembly comprising a transmission disc, a transmission rod, a servo motor, a transmission plate, a lifting rod, a piston, a central rotating cylinder, a three-way pipe, a first check valve, a second check valve, a spray head, and a feed pipe, wherein a partition is provided inside the equipment box, and a positioning bushing is fixedly connected to the lower surface of the equipment box at a position in front of the partition.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0033] This utility model provides, for example Figures 1 to 3 The waste incinerator shown includes multiple equipment boxes 1. A spraying assembly is provided on the lower side of the equipment box 1. The spraying assembly includes a transmission disc 2, a transmission rod 26, a servo motor 27, a transmission plate 3, a lifting rod 34, a piston 35, a central rotating cylinder 4, a three-way pipe 41, a first check valve 42, a second check valve 43, a spray head 44, and a feed pipe 5. Multiple feed pipes 51 are fixedly connected to the surface of the feed pipe 5. A partition 11 is provided inside the equipment box 1. A positioning bushing 12 is fixedly connected to the lower surface of the equipment box 1 at the position in front of the partition 11. The transmission disc 2 is rotatably connected to the front surface of the partition 11. The transmission rod 26 is provided on the rear side of the partition 11 and is rotatably connected to the surface of the multiple equipment boxes 1. The servo motor 27 is fixedly installed on the surface of the rightmost equipment box 1, and the output end of the servo motor 27 is fixedly connected to the right end of the transmission rod 26.
[0034] Multiple sets of equipment boxes 1 and feed pipes 5 are installed on the outside of the furnace body. The spray head 44 extends through the furnace wall into the interior of the furnace body. During use, the servo motor 27 drives multiple sets of transmission discs 2 to rotate through the transmission rod 26. The transmission discs 2 drive the transmission plate 3 to slide up and down inside the equipment box 1, which in turn drives the lifting rod 34 and piston 35 to slide up and down inside the central rotating cylinder 4, drawing the sludge inside the feed pipe 5 into the central rotating cylinder 4. Then, the sludge inside the central rotating cylinder 4 is sprayed out from the spray head 44 into the furnace, atomizing the sludge and spraying it onto the flame. The flame inside the furnace is used to burn the sludge. The intermittent spraying effectively improves the combustion effect of the sludge. In the process of drawing the sludge into the central rotating cylinder 4, the sludge and the internal moisture are mixed evenly again, so that the sludge mixed with water vapor is evenly sprayed on the flame surface, further improving the combustion effect.
[0035] See Figures 4 to 6 A second bevel gear 25 is fixedly connected to the surface of the transmission rod 26 at a position inside each equipment box 1. A first bevel gear 24 is meshed with the side of the second bevel gear 25. The first bevel gear 24 is fixedly connected to the shaft of the transmission disc 2. A first positioning groove 21 is opened on the front surface of the transmission disc 2, and a second positioning groove 22 is opened on the rear surface of the transmission disc 2. The first positioning groove 21 and the second positioning groove 22 are interconnected. A fixing screw 23 is slidably connected inside the first positioning groove 21. The rear end of the fixing screw 23 is stuck inside the second positioning groove 22. A limit groove 31 is opened inside the transmission plate 3. A limit ring 32 is slidably connected inside the limit groove 31. A connecting block 33 is rotatably connected inside the limit ring 32. The connecting block 33 is fixed to the surface of the fixing screw 23. The transmission plate 3 is fixedly connected to the upper end of the lifting rod 34.
[0036] Specifically, during the rotation of the transmission rod 26, multiple sets of second bevel gears 25 will rotate synchronously. The multiple sets of second bevel gears 25 will drive multiple sets of first bevel gears 24 to rotate. The multiple sets of first bevel gears 24 will drive multiple sets of transmission discs 2 inside the equipment box 1 to rotate. During the rotation of the transmission disc 2, the fixing screw 23 will rotate around the axis of the transmission disc 2. At this time, the fixing screw 23, together with the connecting block 33 and the limit ring 32, will drive the transmission plate 3 to move up and down reciprocally inside the equipment box 1.
[0037] See Figure 2 and Figure 3 The transfer cylinder 4 is fixedly connected to the lower surface of the equipment box 1 at the position below the positioning bushing 12. The lifting rod 34 is slidably connected to the positioning bushing 12. The piston 35 is fixedly connected to the lower end of the lifting rod 34 and slidably connected to the transfer cylinder 4. The three-way pipe 41 is fixedly connected to the lower end of the transfer cylinder 4. The first check valve 42 is fixedly connected to the rear end of the three-way pipe 41. The second check valve 43 is fixedly connected to the lower end of the three-way pipe 41. The spray head 44 is fixedly connected to the lower end of the second check valve 43. The front end of the distribution pipe 51 is fixedly connected to the rear end of the first check valve 42.
[0038] Meanwhile, during the reciprocating motion of the transmission plate 3, the lifting rod 34 and piston 35 slide up and down inside the intermediate rotating cylinder 4. When the piston 35 slides upward, it opens the first check valve 42 and closes the second check valve 43, thereby drawing the sludge inside the feed pipe 5 into the intermediate rotating cylinder 4. When the piston 35 slides downward, it closes the first check valve 42 and opens the second check valve 43. At this time, the sludge inside the intermediate rotating cylinder 4 is sprayed out through the spray nozzle 44, and the sludge is sprayed onto the flame for combustion. After the sludge inside the intermediate rotating cylinder 4 is sprayed out, the piston 35 continues to slide upward, drawing the sludge back into the intermediate rotating cylinder 4. During the time of sludge suction, the flame fully combusts the sludge that was previously sprayed out, effectively improving the sludge combustion effect and reducing the generation of particulate dust.
[0039] In addition, during use, by sliding the fixing screw 23 inside the first positioning groove 21 and the second positioning groove 22, the distance between the fixing screw 23 and the axis of the transmission disk 2 can be adjusted, thereby adjusting the rotation radius of the fixing screw 23. At this time, the up and down sliding distance of the transmission plate 3 can be adjusted, thereby adjusting the amount of sludge suction. Different injection amounts can be adjusted for different types of sludge to achieve the best combustion effect.
[0040] The working principle of this utility model is as follows: Through the cooperation of servo motor 27, transmission disc 2 and transmission plate 3, the lifting rod 34 and piston 35 are driven to slide up and down inside the intermediate rotating cylinder 4, so that the sludge inside the feed pipe 5 is drawn into the interior of the intermediate rotating cylinder 4, and then the sludge is sprayed into the furnace body through the spray nozzle 44 to realize intermittent spraying, so that the sludge has a certain combustion time. After the sprayed sludge is fully burned, the next feeding is carried out, which effectively improves the incineration effect of sludge, reduces the residue produced by incineration, and thus reduces the generation of particulate dust and improves the environmental protection effect.
[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
