For a better understanding of the present invention, the structural distribution of the parts of the closed discharge system for barreled material will be described in detail.
Cover barrel mechanism 1
The barrel covering mechanism 1 is used as a main mechanism of the airtight unloading system, not only can seal the opening of the poisonous barreled materials (full barrel), but also can open the opening of the poisonous barreled materials for dumping after being matched and sealed with the expanding mechanism 2.
As shown in fig. 2 to 4, the cover bucket mechanism 1 may specifically include: a stationary cover assembly 11, a valve plate assembly 12 and a safety lock assembly 13 are connected. Wherein, fixed lid assembly 11 can be used to seal the full bucket after holding tightly, and valve plate assembly 12 can be used to open the sealed full bucket after safety lock assembly 13 unblock.
The fixed cover assembly 11 may specifically include: a mounting plate 111, a cover body 112 and a sealing flange 113. Wherein, lid body 112 includes: a cylindrical structure 1121 and an extension plate 1122 formed radially inward from the bottom of the cylindrical structure 1121; sealing flange 113, comprising: an annular body 1131 and a web 1132 formed radially outwardly from the outer circumference of the annular body 1131. Wherein, a flexible member, which may be cloth, plastic or the like having a sealing function, is connected between the extension plate 1122 and the outer circumferential surface of the ring-shaped main body 1131 for sealing the sealing flange 113 and the cover body 112.
The extension plate 1122 and the connection plate 1132 are both annular plates, through holes are formed in two positions, which are opposite to each other in the radial direction, of the extension plate 1122, through holes are formed in positions, which correspond to the extension plate 1122, of the connection plate 1132, the extension plate 1122 and the connection plate 1132 are connected through screws penetrating through the two corresponding through holes, and springs are sleeved on the portions, located between the extension plate 1122 and the connection plate 1132, of the screws. Since springs with the same elastic coefficient are arranged at two positions which are opposite in the radial direction, the sealing degree between the cover barrel mechanism 1 and the full barrel can be adjusted by utilizing the principle that the deformation amount generated by the two springs when the two springs are subjected to external force is the same. That is, after the toxic material barrel is held tightly by the barrel holding mechanism 3, the opening of the toxic material barrel is covered by the barrel covering mechanism 1, so that the opening of the toxic material barrel is sealed, but in the process of covering, a slight offset can occur to the full barrel, at this time, the position of the barrel covering mechanism 1 can be adjusted by the springs arranged at two opposite positions, so that the sealing degree between the barrel covering mechanism 1 and the full barrel can be adjusted.
The annular body 1131 is provided with a first annular groove 1133 on one end surface to which the valve plate assembly 12 is connected, and a second annular groove 1134 is formed on the inner circumferential surface of the annular body 1131 in the circumferential direction. Wherein, the position of the second annular groove 1134 is lower than the position of the first annular groove 1133, the first annular groove 1133 accommodates a first sealing member for sealing the fixed cover assembly 11 and the valve plate assembly 12, and the second annular groove 1134 accommodates a second sealing member for sealing the cover barrel mechanism 1 and the outer edge of the full barrel.
The inner circumferential surface of the annular main body 1131 above the second annular groove 1134 is a cylindrical surface, and the inner circumferential surface of the annular main body 1131 below the second annular groove 1134 is a first conical surface; and the inner peripheral surface of the second sealing piece is a second conical surface, and the conicity of the first conical surface and the conicity of the second conical surface are the same. Through setting up the tapering of first circular conical surface and second circular conical surface the same, in full storage bucket in-process that upwards moves or lid bucket mechanism 1 downwardly moving's in-process, full storage bucket (i.e. the bucket of filling poisonous material, poisonous barreled material promptly) border and second sealing member contact back contact volume grow gradually to realize sealed effect better, and then guarantee that poisonous material zero overflows, can not adjust the contact volume of both better when having avoided plane or side to seal in the prior art, still have the possibility of leakage or excessive.
The above-mentioned fixed lid assembly 11 realizes once sealing of the poisonous barreled material in the process of contacting with the poisonous barreled material and sealing the opening.

Wherein, roll-over door 123 includes: a door body 1231, an adjusting screw 1232, and a pressing plate 1233 pressing the adjusting screw 1232 into the door body 1231. It should be noted that, the door body 1231 is a hollow disc structure, and the diameter of the pressing plate 1233 is about one tenth of the diameter of the door body 1231.
The adjusting screw 1232 is located at the center of the door body 1231, and the head of the adjusting screw 1232 is located in the hollow disc structure, and the head of the adjusting screw contacts the hollow disc structure to form an arc surface. Preferably, the arc surface is an arc surface formed by a minor arc, the tail of the adjusting screw 1232 is in a free state so as to adjust the sealing degree between the cover barrel mechanism 1 and the full barrel, and it is noted that the adjusting screw 1232 has preset weight and is not an ordinary screw, and the specific weight value can be set according to the actual use requirement. It can be appreciated that, since the head of the adjusting screw 1232 is in a minor arc, when the barrel covering mechanism 1 is tightly covered on the opening of the toxic barrel material, if a slight deviation occurs, the adjusting screw 1232 has the function of automatically leveling the door body 1231 under the action of gravity, thereby realizing better sealing of the opening of the toxic barrel material.
The valve plate assembly 12 is arranged so that the opening of the poison barreled material is better sealed, and the poison material basically cannot overflow or leak.
