Description

Technical Field

[0001] The invention relates to an incineration device, in particular to a portable incineration device. Background Art

[0002] Straw is the general term for the stems and leaves of mature crops, usually referring to the remaining part of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (coarse grains) after the seeds are harvested.

[0003] In the past, straw was processed by burning it directly in the open air on the land. Open-air burning would produce large amounts of smoke and particulate matter that would float with the smoke, causing air pollution.

[0004] In recent years, straw treatment methods include returning straw to the field and recycling straw. Returning straw to the field means using a crusher to crush the straw and return it to the field. Recycling straw means using baling machinery to compact and bale the straw. The weight of each bundle is generally more than 100 pounds, which is difficult to load onto a truck by manpower. Therefore, a grab truck is needed to load the straw bales onto the truck. However, Guangxi has a mountainous and hilly basin topography, and part of the land is located on hills and mountains. Crushers, baling machinery, trucks, grab trucks, etc. are all large equipment and it is difficult to drive to this part of the land. As a result, the processing of straw on this part of the land requires more manpower and time. Therefore, in view of the defects of the existing technology, there is an urgent need for a portable incineration device that can be used for straw incineration on narrow plots such as hills and mountains.

DETAILED DESCRIPTION

[0028] In order to enable people skilled in the art to better understand the technical solutions in this application, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0029] Example 1:

[0030] like Figure 1-4 As shown, the present invention provides a portable incineration device that can be transported to land on hills or mountains via a flatbed cart, and then used to burn the straw on the land. The flatbed cart includes a frame 1, universal wheels 2, and a push-pull frame 3. Universal wheels 2 are installed at the four corners of the bottom of the frame 1, and the push-pull frame 3 is installed on one end of the frame 1. When a pulling force is applied forward to the push-pull frame 3, the frame 1 moves forward under the action of the universal wheels 2. When a pushing force is applied backward to the push-pull frame 3, the frame 1 moves backward under the action of the universal wheels 2. A combustion box 31 is installed on the frame 1, and a slag discharge member 23 separates the combustion box 31 into a combustion chamber and a slag collection chamber. The combustion chamber is provided with a feed port, and the slag collection chamber is provided with a slag discharge port 26. A purification box 6 is installed on the top of the combustion box 31. One end of the extraction member 5 is connected to the combustion chamber, and the other end is connected to the purification box 6. A cutting device is installed in the combustion chamber for cutting the straw in the combustion chamber.

[0031] like Figure 1 and 2 As shown, an exhaust pipe 8 is provided on the top of the purification box 6, and the purification box 6 is used to purify the smoke generated by the burning of crop straw in the combustion chamber and the wood ash floating with the smoke.

[0032] like Figure 1 and 2As shown, the purification box 6 is filled with a plurality of adsorption particle bags. The smoke and the particulate matter contained in the smoke are purified by the plurality of adsorption particle bags, the particulate matter contained in the smoke is adsorbed, and the purified smoke is discharged as smokeless gas.

[0033] It should be noted that, in order to facilitate observation of the combustion situation in the combustion chamber, an observation window 33 is provided on the side wall of the combustion chamber. The observation window 33 can facilitate observation of the combustion situation of the straw in the combustion chamber.

[0034] It should also be noted that a plurality of through slots are provided at intervals on the top of the slag discharge member. The number of through slots can be set according to the length of the combustion chamber. The width of the through slots can be 1 to 5 cm. Commonly available widths include 1 cm, 2 cm, 3 cm, 4 cm, or 5 cm. The combustion chamber and the slag collection chamber are connected by a plurality of through slots, and the ash produced by the burning of straw in the combustion chamber falls into the slag collection chamber through the through slots. The through slots are perpendicular to the straw entering the combustion chamber from the feed port, which prevents the cut straw from falling into the slag collection chamber before being completely burned.

[0035] The cutting device can cut the straw into segments in the combustion chamber, reducing the length of the straw in the combustion chamber, which can increase the amount of straw put in and facilitate the combustion of the cut straw.

[0036] In another optional embodiment, if Figures 1 to 4 The figure shows a structure of a cutting device. The cutting device includes a cutting shaft 19, a cutter seat 21, and a cutter 20. The cutting shaft 19 is rotatably mounted on a combustion chamber 31; at least one cutter seat 21 is mounted on the cutting shaft 19; and at least one cutter 20 is mounted on the circumferential surface of the cutter seat 21.

[0037] It should be noted that the number of cutter seats 21 installed on the cutting shaft 19 can be 1, 2 or 3, etc. The number of cutters 20 installed on the circumferential surface of the cutter seat 21 can be 1, 2, 3, 4, 5 or 6, etc.

[0038] The cutter can be in an arc-shaped structure, with the blade located at one end close to the center of the circle, such as Figures 1 to 4 As shown, at this time, the cutting shaft 19 rotates clockwise, and the cutter also rotates clockwise to cut the straw.

[0039] During use, the cutting shaft 19 drives the cutter seat 21 to rotate, and the cutter seat 21 drives the cutter 20 thereon to rotate. The rotating cutter can cut the straw inserted into the combustion chamber into segments, and the cut straw falls into the combustion chamber for burning. The cutter cuts the straw into segments, which is beneficial for increasing the amount of straw put into the combustion chamber.

[0040] In another optional embodiment, if Figures 1 to 4As shown, in order to turn over the straw burning pile on the top of the slag discharge piece, a turning device is added. The turning device is installed in the combustion chamber and is located at the bottom of the cutting device to turn over the straw and straw leaves that fall on the slag discharge piece.

[0041] The burning straw is piled on the top of the slag discharge piece and is stirred by the turning device, which is conducive to the contact between the straw and the air in the combustion chamber and promotes the full combustion of the straw.

[0042] In another optional embodiment, if Figures 1 to 4 As shown, the turning device includes a turning shaft 24 and a turning member 22 . The turning shaft 24 is rotatably mounted on the combustion box 31 . At least one turning member 22 is mounted on the turning shaft 24 .

[0043] It should be noted that the number of flaps that can be installed is 1, 2, 3, 4, 5 or 6. When a plurality of flaps are installed, the plurality of flaps are installed at intervals.

[0044] It should also be noted that the turning member and the cutter seat are staggered to avoid collision between the turning member and the cutter.

[0045] When in use, the turning shaft 24 is driven to rotate, and the turning shaft 24 drives the turning member 22 to rotate. The turning member 22 can effectively turn the burning straw in a pile on the top of the slag discharge member 23, thereby promoting the full combustion of the straw and pushing the slag produced by the combustion into the slag collecting chamber through the slag discharge member.

[0046] In another optional embodiment, a structure of a flip member is provided. Figures 1 to 4 As shown, the turning member 22 is in a U-shaped structure, which can help lift the straw and throw it upward, thereby effectively turning the straw that is burning in a pile and promoting the burning of the straw.

[0047] In another optional embodiment, in order to facilitate the simultaneous driving of the cutting device and the flipping device, a combined driving member is added.

[0048] like Figures 1 to 4 As shown, the combined driving member is respectively connected to the cutting device and the turning device, and drives the cutting device and the turning device to rotate.

[0049] In another optional embodiment, if Figures 1 to 4 As shown, the combined drive assembly includes a first transmission wheel 14, a third transmission wheel 18, a drive member, a rotating shaft 16, and a second transmission wheel 15. The first transmission wheel 14 is in driving connection with the cutting device; the third transmission wheel 18 is in driving connection with the flipping device; one end of the rotating shaft 16 is rotatably connected to the combustion box 31, and the other end is in driving connection with the drive member; the second transmission wheel 15 is mounted on the rotating shaft 16.

[0050] It should be noted that the transmission connection mode between the second transmission wheel 15 and the first transmission wheel 14 and the third transmission wheel 18 can be: meshing transmission connection, chain transmission connection or belt transmission connection.

[0051] The second transmission wheel 15 , the first transmission wheel 14 , and the third transmission wheel 18 are all gear structures.

[0052] The second transmission wheel 15, the first transmission wheel 14, and the third transmission wheel 18 are all connected by a chain drive. A single sprocket is used to connect the second transmission wheel 15, the first transmission wheel 14, and the third transmission wheel 18. The specifications of the second transmission wheel 15 are greater than or equal to those of the first transmission wheel 14 and the third transmission wheel 18. Of course, the cutting device or the turning device can also be driven independently. When the cutting device is driven independently, a chain is installed between the second transmission wheel 15 and the first transmission wheel 14, while no chain is installed between the second transmission wheel 15 and the third transmission wheel 18. When the turning device is driven independently, a chain is installed between the second transmission wheel 15 and the third transmission wheel 18, while no chain is installed between the second transmission wheel 15 and the first transmission wheel 14.

[0053] The second drive wheel 15, the first drive wheel 14, and the third drive wheel 18 are all belt pulleys. The transmission between the second drive wheel 15 and the first drive wheel 14, and between the second drive wheel 15 and the third drive wheel 18, can be connected by at least one belt. Of course, the cutting device or the flipping device can also be driven independently. When the cutting device is driven independently, a belt is installed between the second drive wheel 15 and the first drive wheel 14, while no belt is installed between the second drive wheel 15 and the third drive wheel 18. When the flipping device is driven independently, a belt is installed between the second drive wheel 15 and the third drive wheel 18, while no belt is installed between the second drive wheel 15 and the first drive wheel 14.

[0054] It should also be noted that the driving member can be a hand-driven handle 17 or an electrically driven driving motor 29 .

[0055] The manual drive mode of operation is as follows: the operator holds the handle and rotates it in a circle, and the handle 17 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the second transmission wheel 15 to rotate, and the second transmission wheel 15 simultaneously drives the first transmission wheel 14 and the third transmission wheel 18 to rotate.

[0056] The electric drive type works in this way: the drive motor 29 drives the rotating shaft 16 to rotate, the rotating shaft 16 drives the second transmission wheel 15 to rotate, and the second transmission wheel 15 simultaneously drives the first transmission wheel 14 and the third transmission wheel 18 to rotate. The drive motor 29 is mounted on the outer surface of the combustion box 31 through the support frame 30.

[0057] The first transmission wheel 14 and the third transmission wheel 18 are driven by the second transmission wheel 15. The first transmission wheel 14 drives the cutting shaft 19 of the cutting device to rotate; the third transmission wheel 18 drives the turning shaft 24 of the turning device to rotate.

[0058] It should also be noted that the flatbed cart also carries a battery, which can supply power to the extraction member 5 and the drive motor 29.

[0059] In another optional embodiment, in order to facilitate the insertion of straw into the combustion chamber, a feed channel 13, a cover 12, an adjusting screw 11, an anti-slip seat 10 and a lock seat 9 are added. One end of the feed channel 13 is installed at the feed port on the combustion chamber; the bottom of the cover 12 is hingedly connected to the other end of the feed channel 13, and the top is installed with an anti-slip seat 10; the adjusting screw 11 passes through the anti-slip seat 10 and is threadedly connected to the anti-slip seat 10; the lock seat 9 is installed in the feed channel 13 corresponding to the anti-slip seat 10; wherein, the cover 12 is buckled onto the feed channel 13, and the adjusting screw 11 is threadedly connected to the lock seat 9; the adjusting screw 11 is disengaged from the lock seat 9, and the cover 12 swings open relative to the feed channel 13.

[0060] The length of the feed channel 13 can be 10 to 15 cm. The optional length can be 10, 11, 12, 13, 14 or 15 cm, etc. It can support the straw inserted into the combustion chamber.

[0061] The lid 12 is movably connected to the feed channel 13. When the lid 12 is opened relative to the feed channel 13, straw can be inserted into the combustion chamber through the feed channel 13. The lid 12 movably buckles onto the feed channel 13. The bottom of the lid 12 is hingedly connected to the feed channel 13. The top of the lid 12 is provided with an anti-slip seat 10. The anti-slip seat 10 drives the adjustment screw 11, which is threadedly connected to the lock seat 9. This achieves a fixed connection between the feed channel and the lid, and prevents flames generated by combustion in the combustion chamber from escaping from the feed channel. When the adjustment screw 11 is rotated out of the lock seat 9 until it is separated, the lid 12 can be opened relative to the feed channel 13.

[0062] The cover 12 and the feed channel 13 are connected by a hinge that is limited to 90° rotation, that is, the hinge is limited to swing within 90°. After the cover 12 is opened, it swings downward to 90° relative to the feed channel 13, and the feed channel 13 is docked with the cover 12 through the hinge that is limited to 90° rotation.

[0063] In another optional embodiment, in order to prevent the flame of the combustion chamber from entering the connection between the extraction member and the combustion box, a baffle 27 is additionally installed.

[0064] like Figure 1 and 2As shown, the baffle 27 is installed at the bottom of the connection between the extraction member 5 and the combustion chamber and is tilted upward. When the extraction member 5 extracts the smoke in the combustion chamber, the baffle 27 blocks the flame from entering the extraction member 5.

[0065] To facilitate ventilation into the combustion chamber, at least one through-hole 32 is provided on the bottom side of the combustion chamber. The diameter of the through-hole can be 2 or 3 mm. The number of through-holes 32 provided on the side of the combustion chamber can typically be 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. When the extraction member 5 extracts flue gas from the combustion chamber, the combustion chamber is under negative pressure, and the external atmospheric pressure enters the combustion chamber through the through-hole 32, providing sufficient oxygen to promote the complete combustion of the straw in the combustion chamber.

[0066] It should also be noted that if Figure 1 and 2 As shown, the bottom of the combustion box 31 is a slag collecting chamber, which has a hollow trapezoidal structure. The slag discharge port 26 provided on the slag collecting chamber is inclined, and when unloading slag, the slag in the slag collecting chamber can be discharged from the slag discharge port.

[0067] In order to prevent slag from being discharged from the slag discharge port during the combustion process, a cover 25 is installed on the slag discharge port. The top of the cover 25 is hinged to the slag discharge port, and the cover 25 can be buckled on the slag discharge port 26 under the action of its own gravity.

[0068] In order to further increase the weight of the cover, a counterweight is added, which is installed on the cover 25 and can be installed at the bottom of the cover. The weight-increasing effect of the counterweight can make the cover fit on the slag discharge port and prevent the slag in the slag collection chamber from pushing up the cover.

[0069] According to the above embodiments of the present invention, the specific working mode of the present invention is as follows:

[0070] The flatbed cart transports the combustion device to the land where straw needs to be burned, opens the cover 12, and inserts the straw into the combustion chamber of the combustion box 31 from the feed channel 13. The cutting device is driven, and the cutter 20 on the cutting device cuts the straw inserted into the combustion chamber into segments. The cut straw segments are placed on the slag discharge part 23 at the bottom of the combustion chamber. After adding an appropriate amount of straw, the straw in the combustion chamber is ignited first. After ignition, the extraction part 5 is started, and the atmosphere outside the combustion box 31 enters the combustion chamber through the through hole on the side of the combustion box 31; continue to add straw into the combustion chamber until the combustion chamber is full, then buckle the cover 12 onto the feed channel 13, and use the adjusting screw 11 to threadably connect and fix it with the lock seat 9.

[0071] While the extraction element 5 extracts the flue gas in the combustion chamber and enters the purification box 6, under the action of external atmospheric pressure, external air is sprayed into the combustion chamber through the through holes on the side of the combustion box 31, providing sufficient oxygen for the combustion chamber, which is conducive to the full combustion of the straw in the combustion chamber and reduces the generation of thick smoke. During the combustion process, the turning device is driven, and the turning element 22 on the turning device turns the straw in the combustion chamber, which is conducive to the contact between the straw in the combustion chamber and the injected air, further promoting the combustion of the straw. It can enable the straw in the combustion chamber to achieve gasification combustion, greatly reducing the generation of thick smoke. The flue gas extracted by the extraction element 5 is purified by the purification box 6 and then discharged to the outside through the exhaust pipe. The purification box 6 absorbs and purifies the particulate matter contained in the flue gas, so that the discharged air does not cause pollution.

[0072] During the combustion process, the combustion situation of the combustion chamber can be observed through the observation window 33, and straw can be added to the combustion chamber to burn all the straw on the land. During the combustion process, the slag in the slag collecting chamber can be discharged as required.

[0073] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
