Description

Technical Field

[0001] The invention belongs to the technical field of boilers and relates to a boiler feeding device, in particular to a boiler feeding combustion device. Background Art

Since the two are connected and arranged at different heights, the fuel on the first feed assembly and the fuel on the second feed assembly are separated, so even if the fuel on the second feed assembly burns, the fuel on the first feed assembly will not burn, thereby reducing the occurrence of flashback.

[0003] A boiler feeding and combustion device in the above patent drives the push rod 423 to rotate by a motor 421, so that the roller 424 abuts against the other inner wall of the driving frame 422, thereby pushing the driving frame 422 to reset, and then driving the reset of the feeding plate 410. The fuel falls onto the combustion plate 120 under the obstruction of the baffle plate 330. Because the baffle plate 330 is set on one side of the combustion plate 120, when it blocks the fuel, the fuel will fall to the side close to the baffle plate 330, thereby causing the fuel to be unable to fully contact with the fuel plate 120. Therefore, this problem needs to be solved. Summary of the invention

[0004] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a boiler feeding and combustion device. The technical problem to be solved by the invention is: because the baffle plate is arranged on one side of the combustion plate, when it blocks the fuel, the fuel will fall to the side close to the baffle plate, thereby causing the fuel to be unable to fully contact with the fuel plate.

[0012] With the above structure, the first baffle can be constrained to ensure that it stops moving after moving a certain distance.

[0013] The limiting mechanism includes a receiving groove, which is opened inside the feeding box, and a support rod is slidably connected inside the receiving groove. The bottom of the support rod is fixedly connected to a limiting block, and the limiting block and the third limiting groove are arranged in cooperation with each other.

The present invention can ensure that the fuel can be evenly distributed through the setting of the first discharge port. A constraint column is installed on one side of the first baffle, and the constraint column slides inside the constraint groove. Because the constraint groove is shorter than the second screw, when the feeding box drives the first baffle to move to a certain extent, the constraint groove will constrain the first baffle through the constraint column to stop it from moving. After the first baffle stops moving, the feeding box will continue to move, so that the first discharge port at the bottom of the feeding box can be matched with the second discharge port at the top of the first baffle. After the first discharge port is matched with the second discharge port, the fuel in the feeding box can be poured. Because the feeding box is above the combustion box and the first discharge port is separately set, it can be ensured that the fuel can be evenly distributed inside the combustion box.

[0020] 2. The setting of the ventilation roller of the present invention can supply oxygen to the inside of the combustion box, thereby ensuring that the new fuel can be burned more fully. A ratchet is also installed on one side of the wind roller, and a plurality of pawls are matched on the surface of the ratchet. Due to the shape of the pawl and the ratchet, when the third connecting plate drives the pawl to reset, the pawl will cause the ratchet to rotate, thereby driving the wind roller to rotate synchronously. A wind rod is installed on the surface of the wind roller. Because the wind rod is protruding, when the wind roller drives the wind rod to rotate, the fuel inside the combustion box can be mixed.

[0031] The working principle of the present invention is as follows: when in use, first start the first motor 203, the first screw rod 202 is installed on the output shaft of the first motor 203, and the feeding plate 2 is installed on the surface of the first screw rod 202. Because the feeding plate 2 slides inside the storage bin 1, under the constraint of the storage bin 1, when the first screw rod 202 rotates, the feeding plate 2 can be moved forward to push the fuel into the feeding box 3. When the fuel is loaded, the second motor 304 can be started, and the second screw rod 303 is installed on the output shaft of the second motor 304, and the feeding box 3 is matched with the second screw rod 303 through the first connecting plate 302, and the first connecting plate 302 is constrained by the support frame 7, so that when the second screw rod 303 rotates When the feeding box 3 is moved, a combustion box 5 is installed on one side of the support frame 7, so that with the continuous rotation of the second motor 304, the feeding box 3 will eventually move to the top of the combustion box 5, and a first discharge port 301 is opened at the bottom of the feeding box 3, and the first discharge port 301 is initially blocked by the first baffle 4, so as to ensure that the feeding box 3 can be transported normally, and a constraint column 402 is installed on one side of the first baffle 4, and the constraint column 402 slides inside the constraint groove 103. Because the constraint groove 103 is shorter than the second screw rod 303, when the feeding box 3 drives the first baffle 4 to move to a certain extent, the constraint groove 103 will constrain the first baffle 4 through the constraint column 402, so as to stop it from moving. After the plate 4 stops moving, the feeding box 3 will continue to move, so that the first discharge port 301 at the bottom of the feeding box 3 can cooperate with the second discharge port 403 at the top of the first baffle plate 4. When the first discharge port 301 cooperates with the second discharge port 403, the fuel in the feeding box 3 can be poured. Because the feeding box 3 is above the combustion box 5 and the first discharge port 301 is separately set, it can ensure that the fuel can be evenly distributed inside the combustion box 5. A third connecting plate 505 is also installed at the bottom of the feeding box 3, and the third connecting plate 505 slides inside the combustion box 5. Therefore, when the third connecting plate 505 moves with the feeding box 3, it can discharge the ash inside the combustion box 5. A plurality of wind rollers 6 are also installed in the part, and the plurality of wind rollers 6 are connected to the external air supply mechanism through the guide plate 604, so as to ensure that the combustion box 5 can be supplied with oxygen through the wind roller 6. A ratchet 601 is also installed on one side of the wind roller 6. The surface of the ratchet 601 is equipped with a plurality of pawls 606, and the plurality of pawls 606 are connected to the third connecting plate 505 through the adjusting arm 602. Therefore, when the third connecting plate 505 moves, the pawls 606 will also move synchronously. Because of the shape setting of the pawls 606 and the ratchet 601, when the third connecting plate 505 drives the pawls 606 to reset, the pawls 606 will rotate the ratchet 601, so as to drive the wind rollers 6 to rotate synchronously. A wind rod 605 is installed on the surface of the wind roller 6.Because the wind rod 605 is protruding, when the wind roller 6 drives the wind rod 605 to rotate, the fuel inside the combustion box 5 can be mixed, thereby ensuring that the new fuel can be burned more fully.

[0032] In summary, in the present invention, the core beneficial effect is that the setting of the first feed port can ensure that the fuel can be evenly distributed. A constraint column is installed on one side of the first baffle, and the constraint column slides inside the constraint groove. Because the constraint groove is shorter than the second screw, when the feeding box drives the first baffle to move to a certain extent, the constraint groove will constrain the first baffle through the constraint column to stop it from moving. After the first baffle stops moving, the feeding box will continue to move, so that the first feed port at the bottom of the feeding box can cooperate with the second feed port at the top of the first baffle. After the first feed port cooperates with the second feed port, the fuel in the feeding box can be poured. Because the feeding box is above the combustion box and the first feed port is separately set, it can ensure that the fuel can be evenly distributed inside the combustion box.
