Description

Technical fields:

[0001] This utility model relates to the field of incinerator technology, and in particular to a mechanically rotating automatic ash unloader. Background technology:

[0002] Currently, the grates in existing downdraft incinerators are typically fixed, with ventilation holes or gaps. During operation, primary air enters from the ash chamber, permeates upwards through the ventilation holes or gaps, and provides the oxygen needed for combustion. In practice, these ventilation holes or gaps are often blocked by fuel or clumps of ash packed into the furnace. This requires periodically cranking the lever of the manual ash-cleaning device connected to the grate to slightly move the grate plates, dislodging the ash stuck in the gaps and creating some openings in the compacted fuel to supply oxygen to the upper fuel. However, this method is insufficient to effectively solve the problem, often resulting in uneven oxygen supply, incomplete combustion, and coking. Furthermore, the coked ash formed from incomplete combustion often gets stuck in the grate gaps, requiring manual cranking of the ash-cleaning device lever for removal, significantly increasing labor and fuel costs. Utility model content:

[0003] The technical problem to be solved by this utility model is to provide a mechanical rotary automatic ash unloader. This device realizes three-dimensional ventilation, uniform oxygen supply, more complete fuel combustion, reduces the occurrence of ash and slag coking and clumping, and can automatically remove ash without the need for manual ash removal, saving time and labor.

[0004] The technical solution adopted by this utility model is: a mechanical rotary automatic ash unloader, including a ventilation mechanism, an active rotating tray mechanism, and a support mechanism;

[0005] The ventilation mechanism includes a ventilation cone and an air inlet support cylinder disposed at the lower end of the ventilation cone. Ventilation holes are evenly distributed on the conical wall of the ventilation cone, and multiple arc-shaped material-pulling plates are arranged circumferentially on the upper outer wall of the air inlet support cylinder.

[0006] The active rotating tray mechanism includes an annular tray sleeved on the outside of the air inlet support cylinder, a support assembly supporting the annular tray, and a power transmission assembly located at the lower end of the support assembly. The annular tray is located at the lower end of the arc-shaped material feeding plate. The annular tray is inclined downward from the inside to the outside. The power transmission assembly includes a power gear ring, and the motor drives the power gear ring to rotate through a gear transmission system.

[0007] The support mechanism includes a support frame and a plurality of pulleys arranged circumferentially along the bottom of the power gear ring on the support frame, with the bottom end of the power gear ring resting on the plurality of pulleys.

[0008] Furthermore, the annular tray is tilted downwards at a 15° angle from the inside out.

[0009] Furthermore, the annular tray includes a lower support tray and multiple refractory sheets covering the lower support tray.

[0010] Furthermore, the refractory sheet is made of high-alumina concrete.

[0011] Furthermore, the support assembly includes an outer cylinder, an upper retaining ring disposed at the upper end of the outer cylinder, and a connecting frame. The upper end of the connecting frame is connected to the annular tray, the connecting frame is connected to the inner wall of the outer cylinder, the lower end of the connecting frame is fixed to the upper end of the power gear ring, the outer cylinder is disposed outside the annular tray and there is a gap between it and the annular tray, and the upper retaining ring is disposed on the upper part of the annular tray and there is a gap between it and the annular tray.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] Figure 2 This is a cross-sectional schematic diagram of the present invention.

[0020] Figure 3 This is a schematic diagram of the application of this utility model in a downdraft incinerator. Detailed implementation method:

[0021] like Figure 1 , Figure 2 As shown, a mechanical rotary automatic ash unloader includes a ventilation mechanism, an active rotating pallet mechanism, and a support mechanism.

[0022] The ventilation mechanism includes a ventilation cone 1 and an air inlet support cylinder 2 disposed at the lower end of the ventilation cone. Ventilation holes are evenly distributed on the conical wall of the ventilation cone 1, and multiple arc-shaped material-pulling plates 3 are arranged circumferentially on the upper outer wall of the air inlet support cylinder 2.

[0023] The active rotating tray mechanism includes an annular tray 4 sleeved on the outside of the air inlet support cylinder 2, a support component 5 supporting the annular tray 4, and a power transmission component set at the lower end of the support component 5. The annular tray 4 is set at the lower end of the arc-shaped material feed piece 3. The annular tray 4 is inclined downward from the inside to the outside. The power transmission component includes a power gear ring 6. The motor drives the power gear ring 6 to rotate through a gear transmission system.

[0024] The support mechanism includes a support frame 7 and a plurality of pulleys 8 arranged circumferentially along the bottom of the power gear ring 6 on the support frame 7, with the bottom end of the power gear ring 6 resting on the plurality of pulleys 8.

[0025] The ring-shaped tray 4 is tilted downwards at a 15° angle from the inside out.

[0026] The ring-shaped tray 4 includes a lower support tray 4-1 and multiple refractory sheets 4-2 covering the lower support tray 4-1.

[0027] The refractory sheet 4-2 is made of high-alumina concrete.

[0028] The support assembly 5 includes an outer cylinder 5-1, an upper retaining ring 5-2 located at the upper end of the outer cylinder 5-1, and a connecting frame 5-3. The upper end of the connecting frame 5-3 is connected to the annular tray 4, and the connecting frame 5-3 is connected to the inner wall of the outer cylinder 5-1. The lower end of the connecting frame 5-3 is fixed to the upper end of the power gear ring 6. The outer cylinder 5-1 is located outside the annular tray 4 and has a gap with the annular tray 4. The upper retaining ring 5-2 is located on the upper part of the annular tray 4 and has a gap with the annular tray 4.

[0029] The bottom of the power gear ring 6 is provided with a slide rail 9, which matches the groove of the pulley 8.

[0030] The gear transmission system includes a power gear, which is connected to the output shaft of the motor and meshes with the power gear ring 6.

[0031] like Figure 3 As shown, during operation, fuel enters the incinerator, and primary air enters from the air inlet support cylinder 2, passes through the ventilation cone 1, and permeates outward along the ventilation holes on the cone surface to achieve three-dimensional ventilation, uniform oxygen supply, and more complete combustion of fuel, reducing the occurrence of ash clumping. At the same time, because the outer wall of the ventilation cone 1 is conical, most of the ash after combustion is deposited on the annular tray 4, avoiding clogging of the ventilation holes of the ventilation cone 1.

[0032] During operation, the motor outputs power to drive the power gear ring 6 to rotate. The power gear ring 6 drives the connecting frame 5-3 and the annular tray 4 to rotate. At this time, the fuel after complete combustion produces ash and slag, which is deposited on the annular tray 4. With the cooperation of the arc-shaped material pusher 3 and the rotating annular tray 4, and the relative movement between the annular tray 4 and the arc-shaped material pusher 3, plus the downward tilt angle of the annular tray 4, the ash and slag after the fuel is completely burned is pushed to the outer edge of the annular tray 4 by the arc-shaped material pusher 3 and falls out of the furnace through the gap between the annular tray 4 and the outer cylinder 5-1.

Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
