Technical Field

[0001] The utility model relates to the technical field of roasting machines, in particular to an explosion-proof door for a nut roasting machine. Background Art

[0002] A roaster is a device that evaporates the water inside an object by heating it. Nuts are a type of closed fruit with a hard peel, so a roaster is used during the processing.

[0003] At present, when using a nut roaster, the temperature of the air inside the equipment will rise during the heating process, and the air will expand due to the heat, which will cause the pressure inside the equipment to increase, and exert a certain force on the external cavity. When the force of the air on the external cavity reaches a certain level, that is, the volume of the air pressure expansion is too large, the equipment has no place to exhaust (the equipment cannot have a pressure relief structure), which will cause the equipment to deform under the action of the internal air pressure, and in severe cases, it will explode, posing a great safety hazard. Therefore, an explosion-proof door for a nut roaster is urgently needed to solve the above problem. Utility Model Content

[0004] In order to solve the technical problem that a nut roaster may cause structural damage or even explosion when the internal pressure is too high, the utility model provides an explosion-proof door for a nut roaster, which has a sealing function.

[0025] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figures 1 to 5The invention discloses an explosion-proof door for a nut roaster, comprising at least one sealed door 1 arranged on a door frame 4 of the nut roaster, each of which is provided with at least two locking structures and a safety structure 3 around the sealed door 1, wherein the locking structure comprises a locking part 2, which is arranged on the door frame 4 around the sealed door 1; the locking part 2 comprises a stud 21, a fixing plate 22 and a nut 23, wherein the stud 21 is fixedly arranged on the door frame 4, and the stud 21 is fixed on the door frame 4 by welding, a through hole is arranged on the fixing plate 22, one end of the stud 21 passes through the through hole and is fixedly connected to the nut 23, and the bottom surface of the fixing plate 22 contacts the surface of the sealed door 1; the safety structure 3 comprises a chain 31, which is arranged on the door frame 4, and the chain 31 is also fixedly connected to the sealed door 1. The stud 21 of this embodiment requires a special welding process to ensure that it will not fall off during daily use, and when the internal pressure of the equipment reaches a certain value, the stud 21 is unsoldered. Among them, the special welding process generally adopts argon arc welding, but when welding, it is necessary to ensure that the internal pressure value of the equipment exceeds the rated pressure value (set according to the internal pressure that the nut roaster can withstand), otherwise the welding point of the stud 21 will be damaged.

[0027] The sealing door 1 of this embodiment is pressed against the door frame 4 by at least two locking parts 2, that is, at least two fixing plates 22 press the sealing door 1 against the door frame 4 to achieve the sealing effect of the explosion-proof door. Multiple locking parts 2 press the sealing door 1 to ensure that the equipment has good sealing performance.

[0028] During the baking process, the air inside the equipment expands due to heat, causing the internal pressure of the equipment to increase, making the internal space of the equipment in a slightly positive pressure state. Due to the existence of the sealing door 1, the sealing performance of the equipment is good. Under the slightly positive pressure condition, it is conducive to the air baking of the material.

[0029] When an abnormal situation occurs, the air generated by the baking of the product (nuts) and the air in the equipment itself expand abnormally, and the sealing door 1 will work. The pressure generated by the air inside the equipment causes the stud 21, the fixing plate 22 and the nut 23 to fall off, and the fixed connection between the stud 21 and the door frame 4 is disconnected. The air pressure will push the sealing door 1 out of the frame to release the pressure. Because the chain 31 on the door frame 4 pulls the sealing door 1, the entire sealing door 1 will not fly out, ensuring the safety of the operator.

[0030] The explosion-proof door of this embodiment has a sealed door 1 which is pressed against the door frame 4 by at least two locking parts 2, ensuring that the equipment has good sealing performance; when the pressure is released, the chain 31 prevents the entire sealed door 1 from flying out, ensuring the safety of the equipment and the safety of the operator, and effectively enhancing the safety of the equipment. At the same time, the explosion-proof door of this embodiment has a simple structure. After the explosion-proof door is depressurized, it is convenient to reinstall a new explosion-proof door, which saves time and effort, allowing the nut roaster to quickly restore the pressure relief function (also known as the explosion-proof function).
