China's container transportation began in the 1950s, with the stable development of the 1980s. In the 1990s, China's international container transportation attracted the attention of the transportation industry all over the world. The International Organization for Standardization (ISO) defines containers in terms of: (1) durability, the robustness of which can meet repetitive uses; (2) (3) a convenient device for loading and unloading is provided, and it is particularly convenient to change from one transportation method to another transportation method; (4) (5) a transport facility that meets the requirements of an internal volume of 1 cubic meter or more, or 1 cubic meter or more. The term container does not include a vehicle or conventional packaging. With the advent of the container, it was possible to avoid the unloading of cargo of various cargoes during the transportation, the freight was reduced, the gate to gate transportation was realized, and the international cargo transportation was promoted.

If the cargo to be transported to the container is an intact liquid material such as bitumen, petroleum residue or sulfur, it can easily become a solid state at room temperature. Therefore, when the material is transported in a container in a liquid state and is transported over a long distance, Are in a solid state and can not be flowed, so that they must be heated to a liquid state before they can be taken out of the container.

In Chinese patent document CN1162688A, the combustion chamber is located inside the tank and installed as a U type, and the combustion chamber is a direct combustion heating system, that is, a high temperature gas produced by burning light oil or natural gas A multi-functional petroleum petroleum storage device for a petroleum industry is disclosed in which a tank is heated by flowing into a vessel and heating the tank. Since the distance between the two tubes is large, the heating efficiency is low.

The burner mounting latch member may be formed on the base of the first or second embodiment, Wherein the burner assembly includes a burner case inserted into a container heating port during heating, and the connecting and securing device is for fixing the burner assembly to the container heating port. The connection fastening device includes a suspending member and a clamping mechanism. The hanging member is fixedly connected to the burner assembly, and one end of the hanging member, which is separated from the burner assembly, is inserted into the heating hole so that the burner bar and the burner bar face each other immediately after the heating hole is fixed. And the hanging member includes a first support plate 21 and a second support plate 22 which are integrally formed so as to be perpendicular to each other, and a second screw hole is formed in the first support plate 21, and the burner The burner assembly other than the pass-through burner case is connected by screws, and the burner assembly is inserted into the second screw hole by the screw so as to be engaged with the hanging member. The suspending member is also provided with a reinforcing member. The reinforcing member includes two vertically orthogonal first flat plates 27 and second flat plates 28, and the first flat plate 27 is welded to be perpendicular to the first support plate 21, and the second flat plate 28 is welded to the second support And is welded perpendicularly to the plate 22. The clamp mechanism fixes and connects the burner to the heating tool by clamping the flange of the heating tool. The clamp mechanism includes a movable clamp member and a fixed clamp member sandwiching the flange of the heating tool, and the movable clamp member toward the fixed clamp member And a telescopic member for driving the telescopic member to move. The movable clamp member is a screw 25 having a first screw hole 23 formed therein and a portion of the second holding plate 22 that approaches the engaging plate 25 forms the fixed clamp member and the elastic member is a screw 26 having a male screw, Preferably, the screw 26 is installed through the first screw hole 23, and a rotary knob 29 is provided at one end of the screw 26 remote from the chuck plate 25. The screw 26 is two, and the two screws 26 are parallel Respectively. The mounting member 210 is fixed to the second support plate 22, and the inner surface of the mounting member 210 is provided with a male screw of the screw 26 And a female thread is formed which is engaged and connected.

The burner assembly and the suspension member are integrally formed by fixing the burner assembly to the hanging member so that the burner barrel is inserted into the heating hole of the container, The movable clamp member and the stationary clamp member clamp the flange of the heating port by the stretching and shrinking motion to firmly deflect the burner assembly and the heating port thereby to use a burner equipped with such a connecting and fastening device, The burner can be easily operated and the airflow can be reduced. Further, when the burner is disassembled from the heating port after being heated by the burner, the mixing motion of the elastic member and the movable clamp member and the fixed clamp member is utilized, Since the hand can be disassembled, It can stop the risk and is more secure. In addition, compared with the mounting and dismounting of the burner of the other tank type container, the container-dedicated burner mounting latching member having the direct connection small heating tube according to the present embodiment improves the mounting efficiency by 75% and the decomposition efficiency by 84.62%.

Example 4

The container having the direct continuous compact heating tube according to this embodiment on the basis of any one of the above embodiments further includes an observation hole provided on the upper surface of the container main body. In an exemplary embodiment, a standard container having a length of 6058 mm, a width of 2438 mm, and a height of 2591 mm, that is, a 20-inch standard tank container has an outer diameter dimension of 219 mm of a circular observation hole opened on the upper surface, The cover is fixedly connected by three fixing screws.

Conventionally, the observation ball cover of the bituminous container is required to be opened in the heating and discharging process, and it is prevented that the air is distributed and accumulated in the container tank at high pressure during heating, and the negative pressure is generated in the container tank when discharging, It is important to keep in mind that the observation ball cover is completely open to prevent overheating when heated and unloaded. In the container having the direct heating tube of the present embodiment, the observation hole is fixedly connected to the observation bell cap which seals the observation hole by three fixing screws, thereby opening the inlet of the other tank container when releasing, By operating only three fixing screws of the observation hole, the air flow is reduced by 60% and the operation efficiency is improved as compared with the case of operating. In addition, since the height of the loading surface can be observed through the observation hole during loading, it is possible to prevent the risk such as the biting person rushing back by the field operator or falling inadvertently while opening the loading entrance.
