Description

Technical Field

[0001] The invention relates to the technical field of quarantine and pest control of imported wood, and in particular to a fumigation door sealing structure used for pest control of imported logs. Background Art

[0002] In order to prevent the introduction and spread of quarantine pests, or to reduce the economic impact of controlled non-quarantine pests, fumigation treatment is required. Fumigation is the process of killing pests with fumigants within a certain period of time and in a closed space. The wood fumigation tank becomes a fumigation warehouse after being covered and sealed. According to the requirements of the design principle 4.2 of the fumigation warehouse in the "Technical Specifications for Methyl Bromide Quarantine Fumigation Warehouse": "While meeting the conditions for cargo handling, the fumigation warehouse door should be minimized to improve the air tightness of the fumigation warehouse." Imported logs are relatively large single-body controlled imported quarantine raw materials. The length of imported wood can sometimes reach more than ten meters or even longer. When directly transported by a loader, the wood fumigation warehouse needs to have a larger door body, which must be opened at the same time as the overall roof of the fumigation tank, and must meet the technical requirements for thermal insulation and sealing of the fumigation warehouse door.

[0003] Chinese invention patent CN116711704A (publication date: September 8, 2023) discloses a covered and sealed structure for an imported log pest control fumigation tank. The invention greatly increases the thermal insulation effect of the fumigation tank during wood fumigation by setting up a sealing groove around the top of the fumigation tank and a two-layer sealing structure, thereby achieving the purpose of improving the wood fumigation effect.

[0004] Chinese utility model patent CN220537345U (publication date: February 27, 2024) discloses a large-scale wood fumigation pool roof lifting and opening and closing facility. The utility model sets a sealing end cover and a lifting mechanism at the opening of the fumigation pool, and realizes the opening and closing of the fumigation pool through the transmission connection between the two. During use, the sealing end cover is evenly stressed and will not deform, thereby improving the sealing effect of the fumigation pool when the cover is closed.

[0005] In the prior art, the sealing effect of the fumigation tank is mostly improved by adding a sealing layer, which not only increases the cost, but also makes the sealing structure of the fumigation tank complicated, the process is cumbersome when using it, and cannot meet the requirements of large-scale doors of fumigation warehouses for large-volume imported wood. Summary of the invention

[0006] In view of this, the problem to be solved by the present invention is to design an insulated sealed door that meets the requirements of the "Technical Specifications for Methyl Bromide Quarantine Fumigation Warehouse", which must not only achieve the sealing function of preventing gas escape after the fumigation warehouse door is closed, but also meet the spatial scale requirements when transporting large timber.

[0007] In order to solve the above technical problems, the present invention provides a fumigation door sealing structure for imported logs to remove pests, the structure comprising a fumigation tank body, a fumigation tank roof, and an integral upward-flipping door on the oblique side of the fumigation tank.

[0008] The fumigation tank body includes a fumigation tank bevel, and the overall upward flip door of the fumigation tank bevel includes an upward flip door electric push rod hinge, an upward flip door torque ball bearing hinge, a universal joint bearing and an electro-hydraulic push rod;

[0009] The overall upward flip door of the fumigation tank hypotenuse is a triangular truss space structure frame, the vertex corresponding to the long side of the triangle is connected to one end of the electro-hydraulic push rod, and the vertex close to the fumigation tank body is connected to the bottom of the fumigation tank roof;

[0010] The top of the fumigation tank roof is connected with the other end of the electro-hydraulic push rod.

[0011] An angle sensor is provided at the torque ball bearing hinge of the upward flip door, which is used to monitor the opening angle of the overall upward flip door of the fumigation tank bevel in real time, and transmit it to the control system of the electro-hydraulic push rod in real time to control the extension length of the electro-hydraulic push rod;

[0012] An extruded rubber profile is provided at the front end of the integral upward flip door on the oblique side of the fumigation tank;

[0013] Furthermore, the triangular truss space structure of the overall upward flip door on the oblique side of the fumigation pool is coated with a double layer of membrane material.

[0014] Furthermore, when the oblique side of the fumigation tank is flipped up and closed as a whole, the long side of the triangular truss structure is sealed and connected to the oblique side of the fumigation tank.

[0015] Furthermore, the fumigation tank oblique side integral upward flip door triangular truss is connected to the bottom of the fumigation tank roof by an upward flip door torque ball bearing hinge at the vertex close to the fumigation tank body.

[0016] Furthermore, the vertex corresponding to the long side of the triangular truss of the upward flip door of the fumigation pool is connected to one end of the electro-hydraulic push rod through a universal joint bearing.

[0017] Furthermore, the overall upward flip door structure of the fumigation pool bevel generates a pulling force or a pushing force through the linear telescopic movement of 3 to 5 synchronous electro-hydraulic push rods to open or close the door.

[0018] Furthermore, the membrane material of the integral upper flap door on the oblique side of the fumigation pool is integrated with the membrane material at the bottom of the fumigation pool roof.

[0019] Furthermore, the air barrier formed by the double-layer membrane material applied to the overall flap structure on the oblique side of the fumigation pool realizes the heat preservation function of the fumigation storehouse door.

[0020] Furthermore, when the fumigation tank bevel is flipped up and closed, the electro-hydraulic push rod applies pressure to both sides of the door to make the door fit tightly with the rubber pad on the bevel of the fumigation tank, and the fumigation door is sealed by squeezing the rubber strip to deform.

[0021] Compared with the prior art, the advantages and effects of this application are as follows:

[0022] 1. The present invention discloses a fumigation door sealing structure for removing pests from imported logs. When the oblique side of the fumigation tank is turned up as a whole to close the door, the electro-hydraulic push rod applies pressure to both sides of the door so that the door and the rubber pad of the oblique side of the fumigation tank are closely fitted. The rubber strip is squeezed and deformed to achieve the sealing of the fumigation door. The sealing structure is simple, can be applied to the sealing requirements of large-volume imported wood, has good sealing effect and low cost.

[0023] 2. The enclosed structure of the fumigation door for pest control of imported logs of the present invention designs the overall upturned beveled door of the fumigation tank as a triangular truss space structure, and uses a torque ball bearing hinge to realize the connection between the vertex of the triangular truss and the cover of the fumigation tank. The rolling action of the ball bearing not only makes the power transmission between the various components of the fumigation door more stable and stable, but also reduces friction and reduces wear and damage between mechanical components. At the same time, the flexibility and stability of the ball bearing hinge can also achieve a better connection effect between the various mechanical components.

[0024] 3. The present invention provides a closed structure of a fumigation door for removing pests from imported logs, which forms an air barrier through a double-layer membrane material applied externally on a triangular truss, thereby achieving the heat preservation function of the fumigation door.

[0058] Example 2

[0059] Based on Example 1, this example introduces a torque ball bearing hinge for the upper flip door in the closed structure of the fumigation door for removing pests from imported logs.
