Description

Technical Field

[0001] This utility model belongs to the field of waste treatment technology, and in particular relates to a conveying device for a sealed ash extraction kiln for solid waste incineration. Background Technology

[0002] With the acceleration of urbanization and rapid industrial development, the amount of solid waste (such as household waste, medical waste, and industrial hazardous waste) generated has increased dramatically, making the need for its harmless and reduced-volume treatment increasingly urgent.

[0003] Traditional solid waste incineration technologies mostly employ open or semi-closed kilns. During the solid waste incineration process, the ash formed after the solid waste is burned in the kiln generally falls through the grate. However, due to excessive burning of waste, the ash accumulates below the grate, causing blockages that hinder subsequent ash fall. This makes the process very inconvenient. To address this issue, we propose a sealed ash extraction kiln conveying device for solid waste incineration to solve the aforementioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a solid waste incineration sealed ash removal kiln conveying device that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a solid waste incineration sealed ash removal kiln conveying device, including a kiln body, an exhaust port provided at the top of the kiln body, an ash storage area connected to the surface of the kiln body by a hinge, and a grate provided inside the kiln body. It also includes: an ash storage area located inside the kiln body below the grate; a movable suction head located inside the ash storage area, which absorbs and transports the incinerated ash in the ash storage area when it falls; a sorting area located at the bottom of the kiln body and connected to the ash storage area; and a guide plate installed below the grate at an inclined angle, which contacts the bottom surface of the guide plate when the suction head moves, causing the guide plate to vibrate.

[0006] Preferably, the bottom of the suction head is attached to the bottom inner wall of the ash storage area, a connecting pipe is fixed to one side of the suction head, a flexible hose is fixed to one end of the connecting pipe, one end of the flexible hose passes through the furnace body and extends to the outside where a suction fan is fixed, and the suction fan is installed on one side of the outer wall of the furnace body.

[0007] Preferably, the connecting pipe is installed on the bottom surface of the threaded block, the threaded block is threadedly connected to a lead screw, one end of the lead screw is rotatably connected to the inner wall of the furnace body through a bearing, and the other end of the lead screw passes through the furnace body and extends to the outside where a drive unit is fixedly installed.

[0008] Preferably, a limiting block is fixed to one side of the threaded block, and one end of the limiting block is slidably connected in a groove. The groove is opened on one inner wall of the furnace body, and a through hole is opened in the groove.

[0009] Preferably, a tension spring is fixed to the bottom of the grate, the tension spring is fixedly connected to the guide plate, the surface of the guide plate is provided with screening holes, and semi-circular blocks are fixed on the bottom surface of the guide plate at equal intervals.

[0010] Preferably, the top surface of the suction head is provided with rounded corners, and the top of the suction head is in contact with the semi-circular block.

[0011] Preferably, the classification area includes a collection area located inside the kiln body, the collection area being below the ash storage area, the collection area having a notch at the connection point with the notch, and the bottom inner wall of the collection area having a slope.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0023] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0024] In the description of this utility model, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" 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 this utility model 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 limitations on this utility model.

[0025] Example 1: Refer to Figures 1-6A solid waste incineration sealed ash removal kiln conveying device includes a kiln body 1, an exhaust port 11 on the top of the kiln body 1, an ash storage area 2 connected to the surface of the kiln body 1 by a hinge, and a grate 13 inside the kiln body 1. The device also includes: the ash storage area 2, located inside the kiln body 1 and below the grate 13; a movable suction head 3, located inside the ash storage area 2, which absorbs and transports the incinerated ash in the ash storage area 2 as it falls; a sorting area, located at the bottom of the kiln body 1 and connected to the ash storage area 2; and a guide plate 4, installed below the grate 13 and at an inclined angle, which contacts the bottom surface of the guide plate 4 when the suction head 3 moves, causing the guide plate 4 to vibrate.

[0026] In this invention, during use, the furnace door 12 is manually opened, solid waste is placed inside the furnace body 1, the waste is ignited, and then the furnace door 12 is closed to seal the furnace body 1. The combustion exhaust gas is discharged through the exhaust port 11 connected to the exhaust pipe. After combustion, the solid waste turns into ash, which falls through the grate 13 into the ash storage area 2 for storage. The suction head 3 moves horizontally back and forth inside the ash storage area 2 to promptly extract and transport the accumulated ash to other locations, preventing excessive ash accumulation inside the furnace body 1 and affecting its operation. This design prevents dust from accumulating at the bottom of the grate 13 and causing blockages. Compared to traditional manual cleaning or single vacuuming methods, this design offers more flexible vacuuming performance, prevents dust from remaining in storage areas, and increases the vacuuming range. When the suction head 3 moves, it contacts the guide plate 4, causing the guide plate 4 to vibrate up and down. This vibration prevents dust and foreign objects from getting stuck and simultaneously sieves and sorts foreign objects in the dust, effectively improving the efficiency of subsequent work and making it more convenient to use.

[0027] Example 2: Refer to Figures 1-6 Similar to Example 1, but further: the bottom of the suction head 3 is attached to the bottom inner wall of the ash storage area 2, a connecting pipe 31 is fixed to one side of the suction head 3, a flexible hose 32 is fixed to one end of the connecting pipe 31, one end of the flexible hose 32 passes through the furnace body 1 and extends to the outside where a suction fan 33 is fixed, the suction fan 33 is installed on one side of the outer wall of the furnace body 1, the connecting pipe 31 is installed on the bottom surface of the threaded block 34, the threaded block 34 is threadedly connected to a lead screw 35, one end of the lead screw 35 is rotatably connected to the inner wall of the furnace body 1 through a bearing, the other end of the lead screw 35 passes through the furnace body 1 and extends to the outside where a drive unit 39 is fixedly installed, a limiting block 36 is fixed to one side of the threaded block 34, one end of the limiting block 36 is slidably connected in a slide groove 37, the slide groove 37 is opened on one side of the inner wall of the furnace body 1, and a through hole 38 is opened in the slide groove 37.

[0028] The drive unit 39 can be replaced by a forward and reverse motor or a hand-cranked turntable. In use, the drive unit 39 drives the lead screw 35 to rotate, which in turn causes the threaded block 34 to move left and right inside the ash storage area 2. The threaded block 34 drives the suction head 3 to move synchronously, which can extract dust from multiple locations stored in the ash storage area 2. This avoids the situation in traditional dust extraction methods where the suction position is fixed at a distance and the suction power is insufficient to extract the dust completely. When the suction head 3 moves, the suction fan 33 is started and connected to the suction head 3 through the hose 32 and the connecting pipe 31, so that the suction head 3 generates suction power, which then adsorbs, extracts and transports the dust to the outside of the furnace body 1.

[0029] A tension spring 42 is fixed to the bottom of the grate 13. The tension spring 42 is fixedly connected to the guide plate 4. The surface of the guide plate 4 is provided with screening holes 41. The bottom surface of the guide plate 4 is fixed with semi-circular blocks 43 distributed at equal intervals. The top surface of the suction head 3 is provided with rounded corners. The top of the suction head 3 is in contact with the semi-circular blocks 43. The classification area includes a collection area 6 set inside the furnace body 1. The collection area 6 is located below the ash storage area 2. A notch 5 is provided at the connection between the collection area 6 and the notch 5. The bottom inner wall of the collection area 6 is provided with a slope 61. One side of the furnace body 1 is connected to a material picking door 62 by a hinge. A protrusion is installed on the material picking door 62.

[0030] When the ash from the incineration falls from the grate 13, the unburned parts mixed in with the ash can be screened and isolated through the screening holes 41 on the guide plate 4. Since the guide plate 4 is set at an angle, the unburned impurities that have been screened and isolated are guided by the guide plate 4 and rolled down to the notch 5, falling into the internal storage of the collection area 6. The collection area 6 is provided with a slope 61 to prevent the accumulation of impurities in the collection area 6 from clogging the notch 5. During subsequent cleaning, the debris in the collection area 6 can be cleaned out from the inside of the furnace body 1 by manually opening the material gate 62. When the suction head 3 moves, the top of the suction head 3 comes into contact with the guide plate 4. During the movement, the setting of the semi-circular block 43 causes the guide plate 4 to vibrate as a whole, thereby preventing the debris on the guide plate 4 from clogging the screening holes 41 and improving the screening effect of the device.

[0031] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
