[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] A gasification furnace gas leakage prevention device includes a gasification furnace body 1, the top of the gasification furnace body 1 is fixedly connected to a feed bin 2, the top of the feed bin 2 is hinged with a sealing cover plate 3 by a hinge, one side wall of the sealing cover plate 3 is fixedly connected to a rotating seat 4, positioning plates 5 are rotatably installed on the inner walls of both sides of the rotating seat 4, a guide plate 8 is fixedly installed inside the feed bin 2, and a partition plate 9 is provided at the bottom of the guide plate 8.

[0026] Furthermore, a power assembly 10 for horizontally moving the partition 9 is provided on one side of the feed bin 2. By arranging the feed bin 2 on the gasifier body 1 and coordinating the use of the sealing cover plate 3, the guide plate 8, the partition 9 and the power assembly 10, when loading is required, the sealing cover plate 3 can be opened first, and the material can be loaded into the interior of the feed bin 2. After the material enters the interior of the feed bin 2, it directly falls on the top of the guide plate 8 and the partition 9. Subsequently, the sealing cover plate 3 is used to seal the top of the feed bin 2. Then, the partition 9 is moved by the power assembly 10, so that the feed bin 2 and the interior of the gasifier body 1 are in a connected state. Subsequently, the material above the guide plate 8 automatically slides into the interior of the gasifier body 1, thereby completing the loading operation and effectively solving the problem of gas leakage inside the gasifier body 1 during the loading process.

[0027] Specifically, when the gasifier body 1 is used, solid fuel (such as straw, coal or biomass, etc.) is placed in the gasifier, and the fuel begins to react with the gasifying agent (usually air, oxygen, water vapor or a mixture thereof) at high temperature. In the gasifier, the fuel undergoes a series of complex chemical reactions, mainly including oxidation reaction, reduction reaction and water gas reaction, etc. These reactions are carried out at high temperature to convert the fuel into combustible gas (such as carbon monoxide, hydrogen, methane, etc.) and ash. In the oxidation layer, the fuel undergoes a violent oxidation reaction with the oxygen in the gasifying agent, releasing a large amount of heat and generating carbon dioxide and water vapor. These products undergo a reduction reaction with the carbon in the fuel at high temperature to generate carbon monoxide and hydrogen. In the reduction layer, the carbon monoxide in the gasifying agent undergoes a reduction reaction with the red-hot fuel to generate more coal gas. This layer is the main coal gas generation process. The generated combustible gas is discharged through the gas outlet of the gasifier and becomes a clean gas fuel after purification treatment (such as removing impurities such as dust and tar).

[0028] In a further preferred embodiment, the power assembly 10 includes a fixing frame 1001, which is fixedly mounted on the top of the gasification furnace body 1. An electric telescopic rod 1002 is fixedly mounted on the inner wall of the fixing frame 1001. One end of the telescopic end of the electric telescopic rod 1002 passes through the fixing frame 1001 and is fixedly connected to a connecting rod 1003.

[0029] In a further preferred embodiment, one end of the connecting rod 1003 passes through the feed bin 2 and is fixedly connected to one side of the partition 9, and the connecting rod 1003 is slidably connected to the feed bin 2;

[0030] By adopting the above case, through the combined use of the electric telescopic rod 1002 and the connecting rod 1003, when the telescopic end of the electric telescopic rod 1002 contracts, it can drive the connecting rod 1003 to move, thereby driving the partition plate 9 to move;

[0031] In a further preferred embodiment, two groups of guide rods 11 are slidably inserted into the partition plate 9, and both ends of the two groups of guide rods 11 are fixedly connected to the inner walls on both sides of the two feeding bins 2. By arranging the guide rods 11, the partition plate 9 is limited, making its movement more stable during operation, which is beneficial to further improving the stability of the device;

[0032] In a further preferred embodiment, a U-shaped plate 6 adapted to the positioning plate 5 is fixedly connected to one side wall of the feeding bin 2, and the positioning plate 5 is clamped in the inner cavity of the U-shaped plate 6. By arranging the U-shaped plate 6, after the positioning plate 5 is first clamped in the inner cavity of the U-shaped plate 6, the positioning plate 5 can be positioned by the locking component 7, and then the sealing cover plate 3 can be locked and positioned, which is beneficial to ensuring the airtightness of the top of the feeding bin 2 by the sealing cover plate 3;

[0033] In a further preferred embodiment, locking components for positioning the positioning plate 5 are respectively arranged on both side walls of the U-shaped plate 6. The locking component 7 includes a fixed sliding sleeve 701 fixedly installed on one side wall of the U-shaped plate 6. A locking rod 702 is slidably inserted into the fixed sliding sleeve 701. One end of the locking rod 702 penetrates through the U-shaped plate 6 and is inserted into the positioning plate 5. The other end of the locking rod 702 is fixedly connected to a pulling plate 703. A return spring 704 is further included. One end of the return spring 704 is fixedly connected to one side wall of the pulling plate 703, and the other end of the return spring 704 is fixedly connected to one end of the fixed sliding sleeve 701, and the return spring 704 is movably sleeved on the outer wall of the locking rod 702;

[0034] By adopting the above case, when the sealing cover plate 3 needs to be opened, the pulling plate 703 can be first pulled, thereby driving the locking rod 702 to move until one end of the locking rod 702 is separated from the positioning plate 5. At this time, the positioning plate 5 can be held by hand to open the sealing cover plate 3, which has the characteristics of simple and fast operation;

[0035] Positioning blind holes 12 adapted to the locking rods 702 are respectively opened on both side walls of the positioning plate 5, and one ends of the two groups of locking rods 702 are respectively inserted into the two groups of positioning blind holes 12;

[0036] Specifically, when it is necessary to cover and lock the sealing cover plate 3, the sealing cover plate 3 can be first covered on the top of the feed bin 2. First, pull the pull plate 703, which can带动 the locking rod 702 to move. At this time, the return spring 704 is in a stretched state. Subsequently, the positioning plate 5 is snapped into the inner cavity of the U-shaped plate 6. When one end of the locking rod 702 is aligned with the positioning blind hole 12, then release the pull plate 703, and the return spring 704 can be used to firmly insert one end of the locking rod 702 into the positioning blind hole 12, thereby achieving the effect of quickly positioning the sealing cover plate 3.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
