Description

Technical Field

[0001] This utility model relates to the field of incinerator production technology, specifically to a waste turning device for incinerators. Background Technology

[0002] With the improvement of living standards, the amount of household waste is increasing day by day. The traditional method of landfilling waste disposal not only occupies a lot of land but also pollutes groundwater. Now, incineration is the most common method of waste disposal. However, open burning cannot completely burn the waste, so it is necessary to use incinerators to incinerate the waste.

[0003] Currently, most waste incineration uses grate furnaces, which have the advantages of mature technology, stable and reliable operation, and wide adaptability. Most solid waste can be directly burned in the furnace without any pretreatment. However, during waste incineration, the combustion gas is transported from inside the grate to the waste. The waste at the top is prone to accumulation and does not easily come into contact with the combustion gas, which will cause the upper layer of waste to burn slowly, thus reducing the efficiency of waste incineration. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model uses a drive assembly to drive a rotating shaft inside the furnace body, which in turn drives a flapping plate to rotate. Under the action of a traction structure, the flapping plate drives a traction seat to reciprocate radially along the rotating shaft on its surface. When the first and second push plates rotate, they first scoop up a portion of the waste from the grate. When the rotation reaches its highest point, the first and second push plates rotate simultaneously. The waste on the first push plate falls rapidly under the action of gravity, while the waste on the second push plate falls slowly under the action of the second push plate's tilt angle. This allows the waste to repeatedly come into contact with the combustion-supporting gas, thereby improving the waste's combustion efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] A waste turning device for an incinerator includes a furnace body 1, a grate 2 installed inside the furnace body 1, a rotating shaft 11 rotatably connected to the inner wall of the furnace body 1, a flip plate 12 fixedly connected to the rotating shaft 11, a traction seat 13 slidably connected to the flip plate 12 along the radial direction of the rotating shaft 11, a first connecting arm 17 hinged to the traction seat 13, a second connecting arm 18 hinged to the flip plate 12, one end of the first connecting arm 17 and the second connecting arm 18 being hinged together, a first push plate 14 fixedly installed on the first connecting arm 17, and a second push plate 15 fixedly installed on the second connecting arm 18, both the first push plate 14 and the second push plate 15 being located above the grate 2.

[0024] Please see Figures 1 to 3The rotating shaft 11 can drive the flap 12 to revolve inside the furnace body 1. The flap 12 can drive the traction seat 13, the first push plate 14, and the second push plate 15 to revolve synchronously. When the first push plate 14 and the second push plate 15 pass above the grate 2, they can contact a portion of the waste on the grate 2. Since the waste on the grate 2 moves from left to right, while the first push plate 14 and the second push plate 15 rotate counterclockwise, they can scoop up a portion of the waste as they rotate. As the pusher plate 15 rotates, the first pusher plate 14 and the second pusher plate 15 can flip on the flip plate 12 under the drive of the traction seat 13. The garbage on the first pusher plate 14 can fall back onto the grate 2 under the action of gravity, while the garbage on the second pusher plate 15 can fall slowly. When the second pusher plate 15 rotates to the highest point, the garbage on the second pusher plate 15 will fall quickly. In the above process, the garbage on the first pusher plate 14 and the second pusher plate 15 falls in segments, so it can fully contact the combustion gas and the flame of the burner 22, thereby accelerating the efficiency of garbage incineration.

[0025] It also includes a traction structure. A side plate 10 is fixedly installed on the inner wall of the furnace body 1. The traction structure includes a traction shaft 16 and a track 19. The track 19 is opened on the side plate 10. The rotating shaft 11 is rotatably connected between the two side plates 10. One end of the traction shaft 16 is fixedly connected to the traction seat 13, and the other end of the traction shaft 16 is slidably connected in the track 19. The track 19 is circular in general. The track 19 and the rotating shaft 11 are eccentrically set, and the rotating shaft 11 is located on the center line of the track 19.

[0026] Please see Figure 4In this embodiment, when the rotating shaft 11 rotates, it can drive the traction seat 13 to rotate via the flap 12. The traction seat 13 can then drive the traction shaft 16 to rotate synchronously. Initially, the lowest point of the track 19 is closest to the rotating shaft 11, so the traction seat 13 is furthest from one end of the flap 12. After the rotating shaft 11 rotates 180 degrees, the highest point of the track 19 is furthest from the rotating shaft 11, and the traction seat 13 is closest to one end of the flap 12. Therefore, for the traction seat 13, with the cooperation of the track 19 and the traction shaft 16, when the rotating shaft 11 rotates 180 degrees, the traction seat 13 can translate radially along the rotating shaft 11 on the surface of the flap 12. During the translation of the traction seat 13, the distance between the traction seat 13 and one end of the flap 12 gradually shortens, thus enabling the first connecting arm 17 and the second connecting arm 16 to be pushed. One end of arm 18 rotates, causing the hinged ends of the first connecting arm 17 and the second connecting arm 18 to also rotate. This causes the first connecting arm 17 to rotate the first push plate 14, and the second connecting arm 18 to rotate the second push plate 15. When the traction shaft 16 is at the highest point of the track 19, the first push plate 14 is located below the second push plate 15. Therefore, the garbage on the first push plate 14 has completely fallen off under the action of gravity. However, since the second push plate 15 has a certain angle with the horizontal plane, the garbage can slowly slide off. As the rotating shaft 11 continues to rotate, the angle between the second push plate 15 and the horizontal plane gradually increases, so the garbage on its surface can fall off quickly. This allows the garbage scooped up by the first push plate 14 and the second push plate 15 to fall off in sections and fully contact the combustion-supporting gas, thereby improving the incineration efficiency of the garbage.

[0027] There are at least three traction structures and rotating shafts 11, and the inclination angle of the straight line at the midpoint of the end face of at least three rotating shafts 11 is the same as the inclination angle of the grate 2.

[0028] Please see Figure 1 and Figure 4 The three rotating shafts 11 have different initial angles, which means that when the three rotating shafts 11 rotate synchronously, the first push plate 14 and the second push plate 15 on the first rotating shaft 11 can continuously scoop up the garbage after it is scooped up, as the grate 2 conveys the garbage, thereby realizing the continuous turning of the garbage on the grate 2.

[0029] It also includes a drive assembly, which includes a drive source 20 and a timing belt assembly 21. Two adjacent rotating shafts 11 are connected by the timing belt assembly 21. The drive source 20 is fixedly installed on the outer side wall of the furnace body 1, and the output end of the drive source 20 is connected to one of the rotating shafts 11.

[0030] Please see Figure 5The timing belt assembly 21 enables at least three rotating shafts 11 to rotate synchronously. The drive source 20 can drive one of the rotating shafts 11 to rotate and, under the action of the timing belt assembly 21, can drive the other rotating shafts 11 to rotate. In this embodiment, the drive source 20 can be a motor or a rotary cylinder.

[0031] The top of the furnace body 1 is provided with an exhaust channel 3 and a feed inlet 4. A burner 22 is installed on the top wall of the inner cavity of the furnace body 1. The exhaust channel 3, the feed inlet 4 and the burner 22 are all located above the grate 2. An air inlet pipe 5 is fixedly connected to the side of the furnace body 1. A slag discharge port 6 is provided at the bottom of the furnace body 1. The slag discharge port 6 is located at the end of the grate 2.

[0032] Please see Figure 1 The exhaust channel 3 is used to absorb the exhaust gas generated during waste incineration. The burner 22 is used to continuously ignite and burn the waste. The feed port 4 is used to guide the waste into the grate 2. The air inlet pipe 5 is used to assist in conveying combustion gas from the side, so as to accelerate the waste incineration process together with the combustion gas from the grate 2. The ash discharge port 6 is used to discharge the waste ash after combustion.

[0033] A feeding assembly is provided on the furnace body 1. The feeding assembly includes a feeding block 7, a support 8 and a hydraulic cylinder 9. The feeding block 7 is horizontally slidably connected to the furnace body 1. The feeding block 7 is located at the starting end of the grate 2 and below the feed inlet 4. The hydraulic cylinder 9 is installed on the outer side wall of the furnace body 1 through the support 8. The output end of the hydraulic cylinder 9 is fixedly connected to the feeding block 7.

[0034] Please see Figure 1 The hydraulic cylinder 9 can drive the pusher block 7 to move horizontally inside the furnace body 1, so that the waste inside the furnace body 1 can continuously enter the grate 2. When the pusher block 7 moves away from the grate 2, the waste accumulated on the top of the pusher block 7 can slide off the surface of the pusher block 7 under the obstruction of the furnace body 1, so that the pusher block 7 can push this part of the waste back onto the grate 2 when it resets.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
