[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figs. 1-2 As shown, a waste incinerator feed hopper with isolation function includes a hollow hopper body 1, which is installed on the feed inlet of the waste incinerator. One end of the hopper body 1 is connected to the inner cavity of the waste incinerator, and the other end is provided with an upper cover 2, which is used to cover the open end of the hopper body 1. One end of the upper cover 2 is hinged to the hopper body 1. The hopper body 1 is provided with an opening and closing mechanism, the output end of which is connected to the upper cover 2. The opening and closing mechanism is used to drive the upper cover 2 to rotate along the hinge end, thereby driving the upper cover 2 to open or close.

[0021] The hopper body 1 is equipped with a sealing plate 3. One end of the sealing plate 3 is hinged to the inner wall of the hopper body 1, and the sealing plate 3 can seal against the inner wall of the hopper body 1. By setting the sealing plate 3 to seal against the hopper body 1, the sealing performance of the hopper body 1 can be improved, preventing fumes from escaping from the hopper body 1 during operation, ensuring processing safety, and reducing secondary pollution. The hopper body 1 is equipped with a cover opening mechanism. The output end of the cover opening mechanism is connected to the sealing plate 3. The cover opening mechanism is used to drive the sealing plate 3 to rotate and swing along the hinge end, thereby opening or sealing the inner cavity of the hopper body 1.

[0022] Before dumping the garbage, the upper cover 2 is opened by the opening and closing mechanism, and the sealing plate 3 is opened by the opening mechanism. Then the garbage is dumped into the hopper body 1. After the garbage is dumped, the sealing plate 3 is flipped downward by the opening mechanism, so that the sealing plate 3 blocks the inner cavity of the hopper body 1. Then the upper cover 2 is flipped downward by the opening and closing mechanism, so that the upper cover 2 and the hopper body 1 are closed.

[0023] By installing a sealing plate 3 inside the hopper body 1, and ensuring that the sealing plate 3 is in sealed contact with the inner cavity of the hopper body 1, the leakage of flue gas during waste incineration can be prevented, thereby ensuring operational safety. Furthermore, by providing an opening mechanism, the sealing plate 3 can be opened, facilitating the dumping of waste into the waste incinerator through the hopper body 1.

[0024] Specifically, the opening mechanism includes a pulling component and a pushing component. The pulling component and the pushing component are respectively connected to the hopper body 1, and their output ends are respectively connected to the sealing plate 3. The pulling component is used to pull the sealing plate 3 upward along the hinge end, and the pushing component is used to push the sealing plate 3 downward along the hinge end. When it is necessary to dump the garbage, the pulling component drives the sealing plate 3 to flip upward along the hinge end, thereby opening the inner cavity of the hopper body 1 so that the garbage can be dumped into the garbage incinerator through the hopper body 1. After the garbage is dumped, the pushing component pushes the sealing plate 3 downward along the hinge end, so that the sealing plate 3 can seal the inner cavity of the hopper body 1.

[0025] In this embodiment, the pulling assembly includes a lifting motor 4 and a reducer 5. A mounting frame 6 is fixedly installed on the hopper body 1, and a rotatable drive wheel 7 is provided on the mounting frame 6. A steel cable 8 is sleeved on the drive wheel 7, and the other end of the steel cable 8 is connected to the sealing plate 3. The reducer 5 is fixedly installed on the hopper body 1, and the lifting motor 4 is fixedly connected to the reducer 5. The output end of the lifting motor 4 is connected to the input end of the reducer 5, and the output end of the reducer 5 is connected to the drive wheel 7. When it is necessary to dump garbage, by controlling the lifting motor 4 to work, the reducer 5 is driven to work. The reducer 5 drives the drive wheel 7 to rotate on the mounting frame 6. The drive wheel 7 pulls the steel cable 8 to wind up on the drive wheel 7, and then the steel cable 8 pulls the sealing plate 3 to flip upward along the hinge end, thereby opening the inner cavity of the hopper body 1.

[0026] To improve the stability of the transmission, a rotatable guide wheel 9 is provided on the mounting frame 6, and the steel cable 8 is sleeved on the guide wheel 9. By setting the guide wheel 9, the steel cable 8 can be tensioned so that when the lifting motor 4 is working, the sealing plate 3 can be smoothly pulled up through the steel cable 8, thereby opening the inner cavity of the hopper body 1.

[0027] The pushing assembly includes a pushing cylinder 10, which is fixedly mounted on the outer wall of the hopper body 1. The output end of the pushing cylinder 10 can extend into the inner cavity of the hopper body 1 and abut against the upper surface of the sealing plate 3. Normally, the pushing cylinder 10 is in a retracted state. After the waste is dumped, the sealing plate 3 flips open, and the pushing cylinder 10 is activated, causing its output end to extend until it abuts against the upper surface of the sealing plate 3, pushing the sealing plate 3 downwards along the hinge end. When the opening angle of the sealing plate 3 is less than 90°, under the action of gravity, the sealing plate 3 automatically flips downwards until it seals the inner cavity of the hopper body 1. Afterwards, the pushing cylinder 10 resets, retracting back to its initial state.

[0028] To improve the sealing performance of the sealing plate 3 and the hopper body 1, sealing strips 11 are provided on the inner sidewalls of the hopper body 1 at positions corresponding to the sealing plate 3. When the sealing plate 3 is closed, it seals against the sealing strips 11. Through the cooperation of the sealing plate 3 and the sealing strips 11, the sealing plate 3 can seal against the hopper body 1, improving the sealing performance of the sealing plate 3 and the hopper body 1, further preventing the spread of flue gas and improving operational safety.

[0029] The opening and closing mechanism includes an opening and closing cylinder 12, which is hinged to the hopper body 1. The output end of the opening and closing cylinder 12 is hinged to the upper cover 2. In the initial state, the upper cover 2 is closed to the hopper body 1, and the opening and closing cylinder 12 is in a retracted state. When it is necessary to dump the garbage, the opening and closing cylinder 12 extends to drive the upper cover 2 to flip upward along the hinge end, thereby opening the upper cover 2 to dump the garbage. After the garbage is dumped, the opening and closing cylinder 12 is controlled to retract, so that the upper cover 2 flips downward along the hinge end until the upper cover 2 is closed to the hopper body 1.

[0030] In this embodiment, there are two opening and closing cylinders 12, which are symmetrically distributed on the left and right sides of the hopper body 1. By controlling the two opening and closing cylinders 12 to work simultaneously, the upper cover 2 can be opened more stably, making the opening or closing of the upper cover 2 smoother and improving the stability of the operation. In other embodiments, the number of opening and closing cylinders 12 can be any other number.

[0031] Working principle:

[0032] The top cover 2 closes to the hopper body 1, and the sealing plate 3 seals against the inner wall of the hopper body 1, pushing the cylinder 10 into a retracted state. When it is necessary to dump the garbage, the opening and closing cylinder 12 and the lifting motor 4 are operated by controlling them respectively; the opening and closing cylinder 12 drives the top cover 2 to flip upward along the hinge end, thereby opening the top cover 2; the lifting motor 4 drives the reducer 5 to work, the reducer 5 drives the drive wheel 7 to rotate, the drive wheel 7 rotates and winds the steel cable 8 onto the drive wheel 7, and then the steel cable 8 pulls the sealing plate 3 to flip upward along the hinge end, thereby opening the inner cavity of the hopper body 1. Then the garbage is poured into the hopper body 1 through the upper end of the hopper body 1, and the garbage falls into the garbage incinerator through the inner cavity of the hopper body 1.

[0033] After the waste is dumped, the opening / closing cylinder 12 and the pushing cylinder 10 are operated separately. The opening / closing cylinder 12 drives the upper cover 2 to flip downwards along the hinge end, thereby closing the upper cover 2. The pushing cylinder 10 extends, and the output end of the pushing cylinder 10 contacts the upper surface of the sealing plate 3, pushing the sealing plate 3 to flip downwards along the hinge end. When the opening angle of the sealing plate 3 is less than 90°, under the action of gravity, the sealing plate 3 will automatically flip downwards until the sealing plate 3 and the sealing strip 11 seal against each other, blocking the inner cavity of the hopper body 1. Then the pushing cylinder 10 is reset, causing the pushing cylinder 10 to retract to its initial state. By sealing the inner cavity of the hopper body 1 with the sealing plate 3, it is possible to prevent the flue gas during the waste incineration process from escaping from the hopper body 1, reducing secondary pollution, and also improving the safety of waste incineration operations.

The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
