Intelligent incinerator for garbage incineration

Abstract

This invention discloses an intelligent incinerator for waste incineration. The incinerator includes a furnace body with a combustion zone inside and a drying cylinder above the combustion zone. A discharge port is located at the bottom of the drying cylinder, and a feeding track is located at the top. A rotating component is installed inside the drying cylinder to rotate the waste to be incinerated. A discharge component controls the opening and closing of the discharge port. This invention dries waste in a sealed state, preventing high-temperature flue gas from directly contacting new waste. This avoids the release of large amounts of foul-smelling, toxic organic matter and acidic moisture, reduces dioxin synthesis, and prevents secondary pollution. Simultaneously, during drying, the waste is thrown onto the side wall of the drying cylinder. Since the temperature at the side wall is higher than the center of the drying cylinder during heat transfer, and the waste is dispersed onto the outer wall, it is more easily dried, improving drying efficiency.

Description

Technical Field

[0001] This invention relates to the field of waste incineration technology, specifically to an intelligent incinerator for waste incineration. Background Technology

[0002] In some remote areas, such as islands, mountains, and plateaus, transportation is inconvenient. Transporting waste to processing centers would incur huge transportation costs and could potentially cause secondary pollution. Therefore, using small-scale incinerators can achieve on-site waste treatment, greatly reducing transportation needs and costs.

[0003] Currently, small-scale incinerators typically involve directly feeding new waste into the combustion chamber, where it is dried by direct contact with high-temperature flue gas. During this process, because the new waste contains a high moisture content, it releases large amounts of foul-smelling, toxic organic compounds (VOCs) and acidic moisture. If these substances are directly mixed into the main flue gas without treatment, the downstream purification process will face immense pressure, and they are also prone to resynthesizing dioxins in the low-temperature zone, causing secondary pollution to the environment. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent incinerator for waste incineration to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent incinerator for waste incineration, the incinerator including a furnace body, a combustion zone inside the furnace body, and a drying cylinder arranged above the combustion zone;

[0006] The drying cylinder is hollow inside and is used to store the material to be incinerated; the bottom of the drying cylinder has a discharge port, which is used to discharge the material to be incinerated to the combustion zone; the top of the drying cylinder is provided with a feeding track, through which the material to be incinerated is fed into the drying cylinder;

[0007] The feeding track is located at one end of the furnace body, and a baffle plate is used as a seal. When the baffle plate is removed, waste can be put in. When the baffle plate is closed, waste cannot be put in, and the drying cylinder is kept sealed.

[0008] The drying cylinder is equipped with a rotating component, which is used to drive the material to be incinerated to rotate.

[0009] The discharge assembly controls the opening and closing of the discharge port. When the discharge port is opened, the material to be incinerated is discharged from the drying cylinder. When the discharge port is closed, the material to be incinerated is stored in the drying cylinder for drying.

[0010] Furthermore, the rotating assembly includes a rotating disk, which is rotatably disposed at the bottom of the drying cylinder. The diameter of the rotating disk is smaller than the diameter of the drying cylinder. A material discharge area is provided between the side wall of the rotating disk and the inner wall of the drying cylinder. The material outlet is located in the material discharge area and penetrates through the bottom of the drying cylinder.

[0011] Furthermore, the rotating assembly also includes a rotating sleeve, one end of which passes through the rotating disk and extends to the bottom of the drying cylinder, and the rotating sleeve is fixedly connected to the rotating disk.

[0012] Furthermore, the rotating assembly also includes a drive rod, the first end of which extends into the interior of the rotating sleeve, and the second end of which extends into the top of the furnace body. A second gear is fitted on the outer wall of the second end of the drive rod. A drive motor is installed on the top of the furnace body, and a first gear is fitted on the output shaft of the drive motor. The first gear meshes with the second gear. A cylinder is installed on the top of the furnace body, and the telescopic end of the cylinder is connected to the second end of the drive rod. The drive rod and the rotating sleeve are connected by a splined shaft.

[0013] Furthermore, the top of the rotating disk is provided with an inclined guide bar, the two ends of which are arc-shaped.

[0014] Furthermore, the discharge assembly includes several baffles disposed below the discharge port, and a linkage is provided at the bottom of the drying cylinder. The linkage is used to control the movement of the baffles. When the several baffles move to be spliced ​​into a whole, the discharge port is closed.

[0015] Furthermore, the linkage includes a central turntable, which is rotatably mounted at the bottom of the drying cylinder. Several arc-shaped guide grooves are formed on the side wall of the central turntable. A push rod is provided on the side wall of the baffle plate. The push rod is slidably connected to the bottom of the drying cylinder via a slide rail. One end of the push rod has a vertical guide shaft extending into the arc-shaped guide groove, and the diameter of the guide shaft is the same as the width of the arc-shaped guide groove. A rotating shaft is located at the center of the central turntable. The first end of the rotating shaft extends into the interior of the rotating sleeve, and the first end of the rotating shaft is rotatably connected to the rotating sleeve. A conical groove is provided at the top of the first end of the rotating shaft. The end of the drive rod has a conical protrusion matching the conical groove. An anti-wear rubber layer can be used between the conical groove and the conical protrusion as needed.

[0016] Furthermore, the inner wall of the furnace body is provided with an annular inclined block inside the combustion zone. The space covered by the annular inclined block is inverted conical. The surface of the annular inclined block is provided with several annular protrusions, which are distributed in a stepped manner. The cross-section of each annular protrusion is triangular, and the face corresponding to the longest side of the triangle is an inclined surface. One end of the inclined surface is the high end, and the other end is the low end. The height of the high end relative to the bottom of the furnace body is higher than the height of the low end relative to the bottom of the furnace body. The low end is close to the center of the combustion zone. The specific shape can be referred to in the attached drawings of the instruction manual for the structural distribution of the annular inclined block. An openable discharge door is provided in the combustion zone to facilitate the subsequent removal of the waste remaining after combustion.

[0017] Furthermore, it also includes a controller, a temperature sensor one, and a temperature sensor two. The temperature sensor one is used to collect the temperature inside the furnace body, the temperature sensor two is used to collect the temperature inside the drying chamber, and the controller receives the temperature values ​​collected by the temperature sensor one and the temperature sensor two.

[0018] Furthermore, it also includes an air outlet and an air inlet. The air outlet extends from the outside of the furnace body to the inside of the furnace body and is located above the combustion zone. The air inlet extends from the outside of the furnace body to the combustion zone and is used to supply oxygen to the combustion zone.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention dries waste in a sealed state throughout, thus preventing high-temperature flue gas from directly contacting new waste. This avoids the release of large amounts of foul-smelling, toxic organic matter and acidic moisture, reduces dioxin synthesis, and prevents secondary pollution to the environment. At the same time, during drying, the waste is thrown onto the side wall of the drying drum. Since the temperature at the side wall is higher than that at the center of the drying drum during heat transfer, and the waste is dispersed on the outer wall of the drying drum, it is easier to dry, thus improving drying efficiency.

[0021] 2. This invention first places the garbage around the periphery of the combustion zone, and then gradually gathers it towards the center, avoiding it from falling directly onto the combustion flame. This prevents the flame from going out and ensures that the garbage is fully burned. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example: Figures 1-6 As shown, the present invention provides an intelligent incinerator for waste incineration. The incinerator includes a furnace body 1, a combustion zone 2 is provided inside the furnace body 1, and a drying cylinder 3 is provided above the combustion zone 2. A gap is left between the drying cylinder 3 and the furnace body 1, and flue gas flows through the gap during combustion.

[0034] The drying cylinder 3 is hollow inside and is used to store the material to be incinerated. The bottom of the drying cylinder 3 is provided with a discharge port 4, which is used to discharge the material to be incinerated to the combustion zone 2. The top of the drying cylinder 3 is provided with a feeding track 5, through which the material to be incinerated is fed into the drying cylinder.

[0035] The drying cylinder 3 is equipped with a rotating component, which is used to drive the material to be incinerated to rotate.

[0036] The rotating assembly includes a rotating disk 61, which is rotatably disposed at the bottom of the drying cylinder 3. The diameter of the rotating disk 61 is smaller than the diameter of the drying cylinder 3. A material dropping area is provided between the side wall of the rotating disk 61 and the inner wall of the drying cylinder 3. The material outlet 4 is located in the material dropping area and penetrates through the bottom of the drying cylinder 3.

[0037] The rotating assembly also includes a rotating sleeve 62, one end of which passes through the rotating disk 61 and extends to the bottom of the drying cylinder 3. The rotating sleeve 62 is fixedly connected to the rotating disk 61.

[0038] The rotating assembly also includes a drive rod 63, the first end of which extends into the interior of the rotating sleeve 62, and the second end of which extends to the top of the furnace body 1. A gear 64 is fitted on the outer wall of the second end of the drive rod 63. A drive motor 65 is installed on the top of the furnace body 1. A gear 66 is fitted on the output shaft of the drive motor 65. The gear 66 meshes with the gear 64. A cylinder 67 is installed on the top of the furnace body 1. The telescopic end of the cylinder 67 is connected to the second end of the drive rod 63. The drive rod 63 and the rotating sleeve 62 are connected by a splined shaft.

[0039] Specifically, when waste to be incinerated is placed inside the drying drum 3, the drive motor 65 is started. The drive motor 65 drives gear 1 66 to rotate, gear 1 66 drives gear 2 64 to rotate, gear 2 64 drives drive rod 63 to rotate, and drive rod 63 drives rotating sleeve 62 to rotate synchronously through spline shaft. The surface of drive rod 63 is provided with longitudinal keyway, and the inner wall of rotating sleeve 62, which is fitted on drive rod 63, also has a corresponding keyway, which can keep drive rod 63 and rotating sleeve 62 rotating synchronously. Rotating sleeve 62 drives rotating disk 61 to rotate.

[0040] The top of the rotating disk 61 is provided with inclined guide bars 68. The two ends of the guide bars 68 are arc-shaped. When the rotating disk 61 rotates, the waste is driven to rotate by centrifugal force, and the guide bars 68 on the rotating disk 61 will evenly disperse the waste.

[0041] The discharge assembly controls the opening and closing of the discharge port 4. When the discharge port 4 is opened, the material to be incinerated is discharged from the drying cylinder 3. When the discharge port 4 is closed, the material to be incinerated is stored in the drying cylinder 3 for drying.

[0042] The discharge assembly includes several baffle plates 71 located below the discharge port 4. A linkage component is provided at the bottom of the drying cylinder 3. The linkage component is used to control the movement of the baffle plates 71. When the several baffle plates 71 move to be spliced ​​into a whole, the discharge port 4 is closed.

[0043] The linkage includes a central turntable 72, which is rotatably mounted at the bottom of the drying cylinder 3. Several arc-shaped guide grooves 73 are provided on the side wall of the central turntable 72. A push rod 74 is provided on the side wall of the baffle plate 71. The push rod 74 is slidably connected to the bottom of the drying cylinder 3 via a slide rail. One end of the push rod 74 is provided with a vertical guide shaft 75. One end of the guide shaft 75 extends into the arc-shaped guide groove 73, and the diameter of the guide shaft 75 is the same as the width of the arc-shaped guide groove 73. A rotating shaft 76 is provided at the center of the central turntable 72. The first end of the rotating shaft 76 extends into the interior of the rotating sleeve 62. The first end of the rotating shaft 76 is rotatably connected to the rotating sleeve 62, and a conical groove 77 is provided at the top of the first end of the rotating shaft 76. A conical protrusion 78 matching the conical groove 77 is provided at the end of the drive rod 63.

[0044] Specifically, the cylinder 67 drives the drive rod 63 to move downwards until the conical protrusion 78 at the bottom of the drive rod 63 is tightly fitted with the conical groove 77. At this time, through the action of friction, when the drive rod 63 is rotated in reverse, it will drive the rotating shaft 76 to rotate synchronously. When the rotating shaft 76 rotates, it will drive the central turntable 72 to rotate synchronously. During the rotation of the central turntable 72, the guide shaft 75 will move synchronously through the arc-shaped guide groove 73. The guide shaft 75 will push the push rod 74 outwards. Since the push rod 74 is slidably connected through the slide rail, the push rod 74 will push the baffle plate 71 outwards. When several baffle plates 71 are pushed outwards at the same time, the discharge port 4 is opened, and the garbage in the drying cylinder 3 falls into the combustion zone 2.

[0045] The inner wall of the furnace body 1 is provided with an annular inclined block 11 inside the combustion zone 2. The space covered by the annular inclined block 11 is inverted cone shape. The surface of the annular inclined block 11 is provided with several annular protrusions 12. The several annular protrusions 12 are distributed in a stepped manner. The cross-section of the annular protrusion 12 is triangular. The surface corresponding to the longest side of the triangle is an inclined surface. One end of the inclined surface is the high end, and the other end is the low end. The height of the high end and the bottom of the furnace body 1 is higher than the height of the low end and the bottom of the furnace body 1. The low end is close to the center of the combustion zone 2.

[0046] The bottom side wall of the combustion zone has an openable window for cleaning out unburned solids, or for using a vacuum cleaner to suck out the solids from the combustion zone.

[0047] Specifically, the falling garbage will slide down along the annular inclined block 11 and eventually collect in the center of the combustion zone 2 for incineration.

[0048] It also includes a controller 13, a temperature sensor 1, and a temperature sensor 2. Temperature sensor 1 is used to collect the temperature inside the furnace body 1, and temperature sensor 2 is used to collect the temperature inside the drying chamber. The controller 13 receives the temperature values ​​collected by temperature sensor 1 and temperature sensor 2. The controller 13 is connected to a central control system and can set the drying time of the drying cylinder 3. The central control system can use existing technology.

[0049] It also includes an air outlet 14 and an air inlet 15. The air outlet 14 extends from the outside of the furnace body 1 to the inside of the furnace body 1 and is located above the combustion zone 2. The air inlet 15 extends from the outside of the furnace body 1 to the combustion zone 2 and is used to supply oxygen to the combustion zone 2.

[0050] Working principle: The dried waste is placed in combustion zone 2 for combustion. During combustion, high-temperature gas is generated. As the flue gas rises, it comes into contact with the drying cylinder 3, transferring heat. New waste is then fed into the drying cylinder 3, and the feeding track is closed. At this time, the discharge port 4 is also closed, thus forming a sealed space within the drying cylinder 3 for drying the new waste. During this process, the central turntable 72 throws the waste onto the side wall of the drying cylinder 3. During heat transfer, the temperature at the side wall is higher than that at the center of the drying cylinder 3, and the waste is dispersed throughout the drying cylinder. The outer wall of the drying cylinder 3 is easier to dry, improving drying efficiency. During the drying process, the drying cylinder 3 remains sealed, preventing high-temperature flue gas from directly contacting the new waste. This avoids the release of large amounts of foul-smelling, toxic organic VOCs and acidic moisture, reduces dioxin synthesis, and prevents secondary pollution to the environment. After drying, the waste is discharged from the discharge port. The discharged waste falls closer to the inner wall of the furnace body 1 towards the combustion zone 2, rather than falling directly onto the combustion flame, thus preventing the flame from going out and ensuring complete combustion of the waste.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
