Detailed Description
In order to more fully understand the technical content of the present invention, the technical solution of the present invention will be further described and illustrated with reference to the following specific embodiments, but not limited thereto.
Fig. 1 to fig. 3 show drawings according to an embodiment of the present invention.
A sealing structure of a reaction kettle, the reaction kettle 10 comprises an upper cover 11 and a reaction tank 12, and the upper cover 11 and the reaction tank 12 are mutually covered. A sealing structure 13 is arranged between the upper cover 11 and the reaction tank 12. The sealing structure 13 includes a first sealing assembly 131 and a second sealing assembly 132 both disposed at the joint of the upper cover 11 and the reaction tank 12. The first sealing assembly 131 includes a first groove 121 disposed at the upper end of the reaction tank 12, a second groove 111 disposed at the lower end of the upper cover 11, and a self-tightening sealing member 133 disposed between the first groove 121 and the second groove 111. The self-tightening sealing piece 133 is communicated with the inner cavity of the reaction tank 12 through a communication gap 134. Because certain air pressure is generated in the reaction kettle during the reaction, the sealing effect between the upper cover 11 and the reaction tank 12 is better by utilizing the action of the air pressure on the self-tightening sealing piece 133.
The self-tightening seal 133 includes a first sealing portion 1331, a second sealing portion 1332, and a connecting portion 1333 connecting the first sealing portion 1331 and the second sealing portion 1332. A pressurizing chamber 1334 is provided between the first sealing part 1331 and the second sealing part 1332. The pressurizing chamber 1334 communicates with the inner chamber of the reaction tank 12 through the communication gap 134. The pressurized chamber 1334 is filled with high-pressure gas so that the first sealing part 1331 is tightly attached to the first groove 121 and the second sealing part 1332 is tightly attached to the second groove 111. The pressurizing cavity 1334 is communicated with the inner cavity of the reaction kettle through the communicating gap 134, so that the pressure gas in the inner cavity of the reaction kettle can enter the pressurizing cavity 1334, and under the action of the pressure gas, the first sealing part 1331 and the second sealing part 1332 of the pressure cavity 1334 are deformed and cling to the first groove 121 and the second groove 111, so as to form a sealing effect.
Preferably, for better sealing effect, a plurality of protrusions 1335 are provided on the outer sides of the first and second sealing portions 1331 and 1332. The protrusion 1335 is matched with the receiving groove 1336 formed in the first and second grooves 121 and 111. The first and second sealing portions 1331 and 1332 are opened and tightly attached to the first and second grooves 121 and 111 by the pressure gas, and the protrusion portion 1335 is fitted into the receiving groove 1336. Wherein, the receiving groove 1336 is disposed on the inner wall of the first and second grooves 121, 111.
The second sealing assembly 132 includes a third groove 122 disposed at the upper end of the reaction tank 12, a fourth groove 112 disposed at the lower end of the upper lid 11, and a static sealing member 14 disposed between the third groove 122 and the fourth groove 112. The static seal 14 is compressed and deformed by the third groove 122 and the fourth groove 112 for sealing.
A positioning assembly 15 is disposed between the first sealing assembly 131 and the second sealing assembly 132. The positioning assembly 15 includes a positioning block 113 disposed on the upper cover 11, and a positioning groove 123 disposed on the reaction tank 12. When the upper cover 11 is covered with the reaction tank 12, the positioning block 113 is fitted in the positioning groove 123. Where the first seal assembly 131 forms a first seal barrier, the positioning assembly 15 not only serves for positioning during installation, but also may form a second seal barrier in sealing relation, and the second seal assembly 132 may serve as a third seal barrier. If the first sealing barrier is damaged, after the pressure gas passes through the first sealing barrier, the pressure gas is reduced through the second sealing barrier, the pressure gas is greatly reduced after reaching the third sealing barrier, and the third sealing barrier (the second sealing component 132) can achieve the expected sealing effect through sealing.
Preferably, the positioning groove 123 is circumferentially disposed on the upper end surface of the reaction tank 12, and the positioning block 113 is circumferentially disposed on the lower end surface of the upper cover 11. The positioning groove 123 is a sealing groove, and the positioning block 113 is also sealed, so that the positioning groove 123 and the positioning block 113 can play a role in sealing after installation.
The reaction tank 12 is provided with a first fixing portion 124 on the outer periphery of the upper end thereof. The second fixing portion 114 is provided on the outer periphery of the lower end of the upper cover 11. The first fixing portion 124 and the second fixing portion 114 are fixed to each other by bolts 16. The first fixing portion 124 is disposed at the rim of the reaction tank 12, the second fixing portion 114 is disposed at the rim of the upper cover 11, and the bolt 16 passes through the through hole provided so as to fix the upper cover 11 and the reaction tank 12.
Preferably, the first groove 121 and the second groove 111 are wedge-shaped grooves. Wherein the self-tightening seal 133 is also provided in a wedge-shaped configuration to allow greater tension to be received. The tight sealing element 133 is pressed frequently, tightly clings to the first groove 121 and the second groove 111 after being stressed, and restores to the original shape when not stressed, so that the self-tight sealing element 133 has certain activity, the service life can be prolonged, and aging is delayed.
In addition, reation kettle still is equipped with the controller, with controller electric connection's sensor (such as temperature sensor, humidity transducer etc.), strengthens reation kettle's intellectuality.
The utility model provides a reation kettle can be used in refuse treatment such as life, kitchen, breed, puts into reation kettle with rubbish, and the clean water of output and organic waste material after reation kettle handles are close zero to pollute.
To sum up, the utility model discloses set up first seal assembly and second seal assembly between reation kettle's upper cover and retort, through first seal assembly and second seal assembly double seal, improve sealed effect, avoid leaking, environmental protection safety more. The self-tightening sealing piece of the first sealing assembly improves the sealing performance by utilizing the pressure in the reaction tank, and can be mounted and reused after being detached. The positioning assembly not only can be used as a positioning piece during installation, but also can be used as a sealing barrier, and the sealing property is improved.
The technical content of the present invention is further described by the embodiments only, so that the reader can understand it more easily, but the embodiments of the present invention are not limited thereto, and any technical extension or re-creation according to the present invention is protected by the present invention.
