Abstract

The utility model relates to a medium-sized bulk-in container with a cover, which comprises a container body (8) and a cover (9) which is arranged in the middle of the top of the container body (8). The container is characterized in that the cover (9) comprises a top cover (1), a sub cover (2), a sealing ring (3), a breathable film base (4), a breathable film cover (5), a water-tight breathable film (6) and a main cover (7). The top cover (1) covers over the top of the sub cover (2), and the gap matching is adopted between the top cover (1) and the sub cover (2). The sub cover (2) is connected with the main cover (7) with threads and the sealing ring (3) is embedded at the connecting place. A through hole (2.1) is arranged in the middle of the sub cover (2); and the breathable film base (4) is installed in the through hole (2.1) at the lower part of the sub cover (2) in a tightly connecting way. A grating hole (4.1) is arranged in the middle of the breathable film base (4) and the water-tight breathable film (6) is pasted on the grating hole (4.1) of the breathable film base (4). The cover adopted in the container can avoid liquid from leaking out and can exchange air between the inside and the outside.

Description

IBCS with a lid

Technical field

The utility model relates to a kind of IBCS, especially relates to a kind of IBCS with a lid.Belong to the packing container technical field.

Background technology

IBCS, because its capacity is big, safe and reliable, it is little to take up room, and is suitable for the sea, land and sky transportation, in industries such as chemical industry, food, building materials.Become one of important apparatus.With regard to capacity with regard to taking up room, an IBCS takes up an area of and is equivalent to four common round tanks, but but can hold the liquid that five common round tanks just can hold, traffic cost reduces greatly, and because a series of safety measures that IBCS itself has when designing, make IBCS have higher safety, have better anti-vibration, characteristic such as anti-drop.

IBCS is when the transport liquid material, because jolting of transport vehicle, the liquid of internal tank tends to produce rocking of all directions and variety of way, therefore lid need be installed at the IBCS top, thereby form the leak free IBCS.What generally, IBCS adopted is the common lid that is threaded.But because environmental change is a lot of in transportation and the storage, external temperature changes also very greatly, makes that the liquid generation in the IBCS is expanded with heat and contract with cold, and causes the variation of container internal gas pressure.Because the IBCS volume is bigger, liquid is more, so the liquid effect of expanding with heat and contract with cold can clearly cause container internal pressure excessive when temperature traverse is violent, causes danger.This all is a very big potential safety hazard for transportation and storage, is difficult to guarantee safety.If want to guarantee that ambient temperature is constant, just need be equipped with corresponding conditioning equipment at transport trolley and storage room, this cost that must cause transporting and storing is multiplied.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of under assurance liquid has not leaked prerequisite, can make the IBCS with a lid that gas is in communication with the outside in the container again.

The purpose of this utility model is achieved in that a kind of IBCS with a lid, comprises vessel and lid, and described lid is arranged at the vessel crown center, and the liquid that is used for transporting injects IBCS, it is characterized in that:

Described lid comprises top cover, inferior lid, seal ring, ventilated membrane seat, ventilative membrane cover, waterproof ventilated membrane and main lid,

Described top cover lid places time tops, adopts free-running fit between top cover and time lid, leaves big space between top cover and time lid, thereby time portion of covering is in communication with the outside;

Adopt thread connection between described inferior lid and the main lid, and set the seal ring sealing, prevent that liquid is from master's lid and time lid junction leakage in the junction;

Offer through hole in the middle of described the lid, adopt the stressed joint mode that the ventilated membrane seat is installed in the inferior lid lower through-hole, be provided with the grid hole in the middle of the described ventilated membrane seat, described waterproof ventilated membrane sticks on the grid hole of ventilated membrane seat, because waterproof ventilated membrane itself has waterproof and the big characteristics of Air permenbility, therefore can come in and go out by fluid partitioning, guarantee the normal circulation of gas simultaneously.

Described time the lid outside has ventilative membrane cover again, and ventilative membrane cover is arranged on time lid bottom periphery, is used to stop some foreign.

On the whole, gas can arrive waterproof ventilated membrane from ventilative membrane cover, arrive time top of lid through the ventilated membrane seat after passing waterproof ventilated membrane, reach with ambient atmosphere with the gap of top cover by inferior lid and to communicate, thereby the air of IBCS is in communication with the outside, reaches the effect of self-equalizing air pressure.Meanwhile, because the waterproof action of waterproof ventilated membrane, liquid can't communicate with the external world by above-mentioned passage, simultaneously because the effect of seal ring, liquid also can not communicate with the external world with time junction of lid from main lid, thereby has well reached the sealing function to liquid.

The characteristic of above-mentioned lid is: only allow gas to pass through, liquid can't pass through.This lid is used on the IBCS, when medium-sized bulk container internal pressure changed, gas can see through waterproof ventilated membrane, frees in and out, this makes the gas in the IBCS be communicated with outside air, thereby can be in time, the air pressure inside and outside the equalizing reservoir automatically.Meanwhile, because waterproof ventilated membrane has water-proof function, liquid can't pass through waterproof ventilated membrane, so for liquid and the type bulk container of calling the turn is a fully enclosed container, liquid that can not splashes external container in transportation, has reached the initial purpose of lid.
