Description

Technical Field

[0001] The invention relates to the technical field of quarantine (sealing) and pest control treatment of imported wood, and in particular to a covered and sealed structure of an imported log pest control fumigation pool. Background Art

[0002] The most common method of treating imported logs for pest control is fumigation. Fumigation is the process of using fumigants (mostly methyl bromide) to kill harmful organisms in a sealed space for a certain period of time.

[0003] In the past, fumigation methods mostly used tent covering on the fumigation pool. When the wood was fumigated, the heat dissipated too quickly due to the tent covering method. In the low temperature of winter, when the heating system was turned on, the temperature was difficult to meet the requirements of fumigation treatment. The test also found that some sandbags had leakage at the joints, and the tent was scratched and damaged when covering, which resulted in poor insulation effect and affected the fumigation effect. Summary of the invention

[0004] In view of the above problems existing in the existing log fumigation, the present invention aims to provide a covered closed structure for an imported log pest removal fumigation pool with high sealing performance, excellent thermal insulation performance and good fumigation effect.

[0005] The specific technical solutions are as follows:

[0006] A capping and sealing structure for an imported log pest removal fumigation tank is used to seal the top opening of the fumigation tank, comprising: a sealing top cover, wherein the sealing end cover matches the open end of the fumigation tank and is sealed with the open end of the fumigation tank through a sealing structure, wherein the sealing structure comprises:

[0007] The airtight flexible membrane material is used to wrap the openable steel structure roof by applying prestress to form a sealed top cover to cover a large area of ​​the fumigation pool;

[0008] The gaps between the fumigation tank and the roof are sealed by various structural structures (sealing strips);

[0009] A first sealing strip, wherein the first sealing strip is disposed around the bottom of the sealing top cover, and the bottom of the first sealing strip is concavely disposed;

[0010] A second sealing strip, wherein the second sealing strip is disposed around the top of the fumigation tank, the top of the second sealing strip is convexly disposed, and the second sealing strip is concavely and convexly matched with the first sealing strip for sealing;

[0011] A rubber plate, the top of which is arranged around the bottom of the sealing top cover, a sealing groove is arranged around the top of the fumigation tank, a sealing liquid is contained in the sealing groove, and the bottom of the rubber plate extends into the sealing liquid.

[0012] As a further improvement and optimization of this solution, the sealing groove is located on the outside of the second sealing strip.

[0013] As a further improvement and optimization of this solution, the top of the rubber plate is fixed to the bottom side of the sealing end cover.

[0014] As a further improvement and optimization of this solution, the rubber plate and the sealing end cover are fixed by bolts.

[0015] As a further improvement and optimization of the present solution, the sealing end cover includes a skeleton and a sealing layer coated on the outside of the skeleton.

[0016] As a further improvement and optimization of this solution, the sealing layer is a membrane structure.

[0017] As a further improvement and optimization of the present solution, the sealing structure further comprises a frame, the sealing end cover is longitudinally slidably mounted on the frame, a lifting mechanism is provided on the frame, the lifting mechanism is transmission-connected to the sealing end cover, and is used to drive the sealing end cover to rise and fall, so that the sealing end cover opens and closes the fumigation pool.

[0018] As a further improvement and optimization of this solution, the lifting mechanism is a chain hoist crane structure.

[0019] Compared with the prior art, the above technical solution has the following positive effects:

[0020] (1) In the present invention, when the sealing end cover seals the fumigation tank, the sealing effect between the first sealing strip and the second sealing strip is increased by the concave-convex sealing matching structure of the first sealing strip and the second sealing strip, thereby increasing the sealing effect of the sealing end cover on the fumigation tank. At the same time, the rubber sheet is again extended into the sealing liquid to further seal the fumigation tank, which greatly increases the heat preservation effect of the fumigation tank when fumigating wood, thereby improving the fumigation effect of the wood.

[0021] (2) In the present invention, the sealing end cover is automatically raised and lowered by the lifting mechanism to open and close the fumigation tank, thereby facilitating the transportation of wood and improving the fumigation efficiency of wood. BRIEF DESCRIPTION OF THE DRAWINGS
