Abstract
The utility model relates to a kind of special MDI storage tank, comprises the top cover and lower tank made by corrosion-resistant steel, and the tank mouth inwall of described lower tank is provided with negative thread, and described tank mouth top is provided with the annulus of a circle projection; A projection is provided with below described top cover, described projection side is provided with the outside thread of working in coordination with the negative thread of described tank mouth, the bottom of described top cover is provided with a circle groove around described projection, be provided with the seal ring of working in coordination with described annulus in described groove, the upper end of top cover is provided with three handles by annular array.The utility model leak tightness is good, and the stainless steel material of employing can prevent again MDI and tank body from reacting rotten, easy realization rational in infrastructure.
Description
Technical field
The utility model relates to storage tank field, specifically refers to a kind of special MDI storage tank.
Background technology
Methyl diphenylene diisocyanate is called for short MDI, is the important intermediate of synthesis of polyurethane, can be made into a series of carbamate insecticides, bactericidal agent, herbicide, also for improvement of the water-proofness of plastics, fabric, leather etc.Two functional groups and above isocyanates can be used for the Polyurethane foam, rubber, elastic fibers, coating, adhesion agent, synthetic leather, imitation wood etc. that synthesize a series of function admirable, are industrial and synthesis material important in daily life.
MDI requires harsh to condition of storage, needs to fill in a reservoir nitrogen and completely cuts off water, oxygen etc. in air, needs again at 5 DEG C of environment once.Be white solid under MDI normal temperature, easily react with water under natural surroundings, and easily self-polymeric reaction discharges a large amount of heat and causes hidden danger such as catching fire, MDI character of invigorating blood circulation is active, the reactions such as easy and iron, copper, steel.And MDI easily to evaporate in air and can produce human eye and skin after reaching finite concentration and stimulates.So study the condition of storage of MDI, the storage tank designing a kind of MDI of being applicable to is the purpose of this utility model.
Utility model content
For above-mentioned prior art Problems existing, the utility model is to provide a kind of special MDI storage tank, effectively can solve above-mentioned prior art Problems existing.
The technical solution of the utility model is:
A special MDI storage tank, comprises the top cover and lower tank made by corrosion-resistant steel, and the tank mouth inwall of described lower tank is provided with negative thread, and described tank mouth top is provided with the annulus of a circle projection; A projection is provided with below described top cover, described projection side is provided with the outside thread of working in coordination with the negative thread of described tank mouth, the bottom of described top cover is provided with a circle groove around described projection, be provided with the seal ring of working in coordination with described annulus in described groove, the upper end of top cover is provided with three handles by annular array.
Advantage of the present utility model:
(1) this storage tank is made up of corrosion-resistant steel, avoids the problem that traditional iron bucket can react with MDI, and corrosion-resistant steel has again good permeability of heat, preservation of can conveniently lowering the temperature simultaneously; (2) this tank body leak tightness is good, and after can ensureing to be filled with nitrogen, tank interior can not be entered steam or air etc., prevents MDI and water or oxygen etc. from reacting and generates heat; (3) handle arranged above top cover can facilitate screwing hermetic or outward winding, and MDI needs in anaerobic anhydrous and take under filling the environment of nitrogen, and top cover directly takes off and opening can be allowed larger, so the time of taking out required for MDI is shorter, ensures the safety of operative employee.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cap structure schematic diagram of the present utility model.
Detailed description of the invention
Now embodiment is described in further detail structure of the present utility model by reference to the accompanying drawings for the ease of it will be appreciated by those skilled in the art that:
With reference to figure 1, Fig. 2, a kind of special MDI storage tank, comprises the top cover 1 and lower tank 2 made by corrosion-resistant steel, and tank mouth 23 inwall of described lower tank 2 is provided with negative thread 22, and described tank mouth 23 top is provided with the annulus 21 of a circle projection; A projection 14 is provided with below described top cover 1, described projection 14 side is provided with the outside thread 12 of working in coordination with the negative thread 22 of described tank mouth 23, the bottom of described top cover 1 is provided with a circle groove (mark) around described projection 14, be provided with the seal ring 13 of working in coordination with described annulus 21 in described groove, the upper end of top cover 1 is provided with three handles 11 by annular array.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
