[0002] With the development of industry, a large amount of hazardous waste is generated in the production process, and the number is increasing day by day. In order to solve this problem and avoid direct pollution of the environment by hazardous waste, the treatment personnel generally set up a rotary incinerator to burn the hazardous waste and produce treated materials that do not affect the environment, so as to achieve the purpose of purifying the environment and minimizing the pollution of the environment by hazardous waste; in the prior art, the rotating shaft inside the rotary combustion furnace stirs and ventilates the hazardous waste entering the device through the cutter and the fan blade respectively (the smoke generated by the primary combustion of the hazardous waste is directed and discharged), and then the smoke generated by the combustion is discharged upward to the second combustion chamber, and finally The flue gas is treated into pollution-free reactants (including gases), but the rotation and stirring degree of the rotating shaft located in the first combustion is not deep enough, so that the accumulated hazardous waste is often not able to be fully cut and crushed, thereby failing to increase the contact area with the air, which is not conducive to the full combustion treatment of the hazardous waste. Due to the limited internal space of the first combustion chamber, the pressure between the accumulated hazardous wastes increases, resulting in local accumulation. In the area far away from the rotating shaft, the accumulated hazardous wastes cannot fully move relative to each other, resulting in a decrease in the overall kinetic energy of the hazardous waste, and easily clogging the burner, and finally causing the device to malfunction.

[0015] S1. Start the motor and drive the shaft, fan blades, cutter 1, bottom rolling mechanism, movable column and cutter 2 to rotate;

[0016] S2. Pour hazardous waste (hereinafter referred to as material) into the feed mechanism and continuously fall into the inner cavity of the No. 1 combustion chamber along the feed cylinder, supported by the filter screen;

[0017] S3. Then, the cutter pair cuts the material and drives the material to move, roll and accumulate toward the inner wall of the No. 1 combustion chamber. The movable column drives the cutter to perform a second cut on the material during the second revolution and rotates at the same time;

[0018] S4. Then, the bottom plate rotates due to the squeezing when it contacts the material, thus rolling the material from top to bottom;

[0019] S5. Then, the movable column drives the cutter 2 to roll and push the material located in the outer ring of the inner cavity of the No. 1 combustion chamber toward the inner ring area through revolution + rotation, so that the cutter 1 repeatedly cuts the material;

[0020] S6. After the material is tumbled and cut off, the cutter 1 is turned on to burn the material in the combustion chamber No. 1. Through the tumbling of the cutter 1 and the cutter 2, the burning material is fully in contact with the air and produces smoke;

[0021] S7. The flue gas passes through the vent hole and enters the inner cavity of the No. 2 combustion chamber upwards, and the No. 2 burner is turned on to fully burn the flue gas and produce harmless substances;

[0022] S8. The harmless substances are discharged along the exhaust pipe, and the feed barrel is heated so that the materials passing through the feed barrel are preheated;

[0024] The working principle and beneficial effects of the present invention are:

[0025] 1. This device has been redesigned to greatly improve the tumbling and stirring degree of the material, which can avoid the blockage of the No. 1 burner. The material cut by the rotation of the cutter one gathers in the middle position of the No. 1 combustion chamber. The bottom tumbling mechanism, the movable column and the cutter two are driven by the rotating shaft to rotate, and the movable column and the cutter two are generated. The revolution, on the one hand, is used to cut the material by the cutter two, and the rotation of the cutter two and the movable column caused by the squeeze of the material. When the movable column and the cutter two are in revolution, the material is tumbling, so that the material located in the outer ring area of ​​the No. 1 combustion chamber begins to move toward the middle position, and the cutter one can be fully aligned for cutting and stirring, thereby greatly increasing the tumbling and stirring degree of the device for the material, and avoiding the blockage caused by the accumulation of materials and the inability to fully stir.

[0026] 2. Then, by arranging a bottom tumbling mechanism on the upper and lower sides of the inner cavity of the No. 1 combustion chamber, the kinetic energy of the material when tumbling in the No. 1 combustion chamber is increased, and the rotating column and the bottom plate installed in the installation groove are pressed to the bottom layer of the material accumulation to obtain huge pressure, and then rotated under the drive of the rotating shaft. At the same time, the bottom plate is squeezed by the material and rotates in the process of being driven to revolve, so that the material at the bottom layer is tumbled up and down and stirred. This design can achieve real-time fluffing function for the material accumulated at the bottom, which not only avoids clogging the filter and the No. 1 burner, but also increases the contact area between the material and the air, making the material combustion efficiency higher.

[0027] 3. This device also adds a newly designed feeding mechanism, which uses the gravitational potential energy of the material to cooperate with the inclined plate to convert it into mechanical energy for the installation shaft and the inclined plate to rotate. According to the inclined design of the inclined plate, it will generate a positive pressure wind force vertically downward along its own axis. This positive pressure wind force cooperates with the material to enter the inner cavity of the No. 1 combustion chamber vertically downward, which is beneficial to increase the air content in the inner cavity of the No. 1 combustion chamber and is more conducive to combustion. At the same time, a "one-way valve" is formed with the continuously falling material to prevent the No. 1 combustion chamber from flashing back into the feeding barrel. The overall design of the feeding mechanism changes the feeding direction of the material and realizes the overall integrated design of the incinerator body, which is beneficial to the continuous feeding of the device.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1:

[0040] A rotary incinerator for hazardous waste treatment comprises an incinerator body 1, an exhaust pipe 6 and a feeding mechanism 7 are respectively installed on the top of the incinerator body 1, the inner cavity of the incinerator body 1 is respectively arranged to be a No. 1 combustion chamber 101 located in the middle, a No. 2 combustion chamber 102 located on the upper and lower sides, and a discharge chamber 103, a No. 1 burner 4 is installed inside the No. 1 combustion chamber 101, a No. 2 burner 5 is installed inside the No. 2 combustion chamber 102, two sets of telescopic rods 3 are installed on the outer surface of the incinerator body 1, the telescopic ends of the telescopic rods 3 are fixedly connected with a connecting block 18, one end of the connecting block 18 is fixedly installed with a filter screen 13 located at the bottom of the No. 1 combustion chamber 101, and the inner wall of the discharge chamber 103 is connected by a connecting column 1. 0 is installed with a fixed block 11, a motor 12 is installed at the bottom of the fixed block 11, a rotating shaft 121 is fixedly installed on the output shaft of the motor 12, an isolation block 8 is fixedly installed between the inner walls of the No. 1 combustion chamber 101 and the No. 2 combustion chamber 102, the rotating shaft 121 penetrates upward and passes through the filter 13 and the isolation block 8 in sequence, a plurality of groups of cutters 14 symmetrically distributed in the left and right directions are fixedly installed on the outer surface of the rotating shaft 121, two groups of symmetrically distributed bottom tumbling mechanisms 15 are fixedly installed on the left and right sides of the outer surface of the rotating shaft 121, and two groups of movable columns 16 are rotatably installed through the bottom tumbling mechanisms 15, and a cutter 2 17 is fixedly installed on the outer surface of the movable column 16, and a vent hole 9 is opened on the top of the isolation block 8;

[0041] The bottom rolling mechanism 15 includes a fixed plate 151 mounted on the surface of the rotating shaft 121, a placement groove 152 is formed on the top of the fixed plate 151, a mounting groove 153 is formed on the inner wall of the placement groove 152, and a rotating column 154 is rotatably mounted through the mounting groove 153, a bottom plate 155 is fixedly mounted on the outer surface of the rotating column 154, and the movable column 16 is rotatably mounted between the upper and lower sets of fixed plates 151;

[0042] When the material enters the No. 1 combustion chamber 101 through the feeding mechanism 7, the motor 12 drives the rotating shaft 121 and the cutter 14 to firstly perform rotational cutting and stirring on the material located in the middle position, and at the same time, drives the bottom tumbling mechanism 15, the movable column 16 and the cutter 2 17 to revolve, and the cutter 2 17 cuts and stirs the material located in the outer ring area. At the same time, the cutter 2 17 starts to rotate under the extrusion of the material, and rolls the material located in the outer ring toward the middle position, so that the cutter 14 cuts and tumbles it twice. This design makes the material entering the No. 1 combustion chamber 1 01 The material in the inner cavity rolls from the outer ring to the inner ring, thereby increasing the degree of rolling of the material. During the rotation of the bottom tumbling mechanism 15, the huge pressure on the bottom formed by the accumulation of materials from top to bottom exerts pressure on the bottom plate 155, and in the process of the rotating shaft 121 driving the fixed plate 151 to rotate, the bottom plate 155 is driven to rotate. The rotating bottom plate 155 synchronously rolls the material at the bottom layer to loosen its bottom, which is more conducive to increasing the contact area with the air during subsequent combustion, so that the material burns more fully and will not block the No. 1 burner 4.

[0043] The present device has been redesigned to greatly enhance the degree of tumbling and stirring of the material, and can avoid clogging of the No. 1 burner 4. The material cut by the rotating cutter 14 is gathered in the middle position of the No. 1 combustion chamber 101. The bottom tumbling mechanism 15, the movable column 16 and the cutter 17 are driven to rotate by the rotating shaft 121, and the movable column 16 and the cutter 17 are rotated. On the one hand, the cutter 17 is used to cut the material, and the cutter 17 and the movable column 16 are squeezed by the material. The rotation of the movable column 16 and the cutter 17 causes the material to tumble when the movable column 16 and the cutter 17 revolve, so that the material located in the outer ring area of ​​the No. 1 combustion chamber 101 begins to move toward the middle position, and the cutter 14 can be fully aligned for cutting and stirring, thereby greatly increasing the degree of tumbling and stirring of the material by the device, and avoiding the blockage caused by the accumulation of materials and the inability to fully stir.

[0044] Then, by arranging a bottom tumbling mechanism 15 on the upper and lower sides of the inner cavity of the No. 1 combustion chamber 101, the kinetic energy of the material when tumbling in the No. 1 combustion chamber 101 is increased, and the rotating column 154 and the bottom plate 155 installed in the installation groove 153 are pressed to the bottom layer of the material accumulation to obtain huge pressure, and then rotated under the drive of the rotating shaft 121. At the same time, the bottom plate 155 is squeezed by the material and rotates in the process of being driven to revolve, so that the material at the bottom layer is tumbled up and down and stirred. This design can realize real-time fluffing function for the material accumulated at the bottom layer, which not only avoids clogging the filter 13 and the No. 1 burner 4, but also increases the contact area between the material and the air, making the material combustion efficiency higher.

[0045] Embodiment 2:

The bottom of the feeding mechanism 7 passes through the bottom of the isolation block 8 and communicates with the inner cavity of the No. 1 combustion chamber 101.

[0047] The feed barrel 71 is used for feeding materials. The feed barrel 71 is located above the No. 1 combustion chamber 101, which can avoid opening holes from the side of the incinerator body 1 and maintain the integrity of the incinerator body 1.

[0050] When the material moves downward along the inner wall of the feed barrel 71, it will continuously push the inclined plate 75 and drive the mounting shaft 74 and the inclined plate 75 to rotate. According to the inclined design of the inclined plate 75, it will generate a positive pressure vertically downward along its own axis and continuously act on the inner cavity of the No. 1 combustion chamber 101. This positive pressure not only prevents the backfire phenomenon that may occur inside the No. 1 combustion chamber 101 during combustion, but also increases the air content in the No. 1 combustion chamber 101, which is more conducive to combustion.

[0051] The present device also incorporates a newly designed feeding mechanism 7, which utilizes the gravitational potential energy of the material in conjunction with the inclined plate 75 to convert it into mechanical energy for the rotation of the mounting shaft 74 and the inclined plate 75. According to the inclined design of the inclined plate 75, it will generate a positive pressure wind force vertically downward along its own axis. The positive pressure wind force vertically downward cooperates with the material to enter the inner cavity of the No. 1 combustion chamber 101, which is beneficial to increase the air content in the inner cavity of the No. 1 combustion chamber 101 and is more conducive to combustion.
