Abstract
The utility model provides an MDI (diphenyl-methane-diisocyanate) melting system. The melting system comprises a melting tank and a steam condensate reclaiming tank, wherein the melting tank is used for melting MDI and is provided with a first water inlet and a first water discharge port; a feed port for feeding MDI into an MDI bucket is arranged at the top of the melting tank; the steam condensate reclaiming tank is provided with a second water inlet and a communicating port; and the communicating port is connected with the first water inlet through a pipe. The MDI (diphenyl-methane-diisocyanate) melting system disclosed by the utility model has the advantage that as steam condensate meeting the requirement of MDI melting can be utilized, the wasting of resources is avoided.
Description
[technical field]
The utility model relates to the device systems in a kind of spinning field, relates in particular to the thawing system of a kind of MDI.
[background technology]
Methyl diphenylene diisocyanate (being MDI) is the very strong material of a kind of reactivity, is solid-state at normal temperatures, and it generally is to adopt bucket or the tank of closure to store.
In the spinning field, use again after often needing to place water-bath about 70 ℃ that the MDI in the MDI bucket is melted first the MDI bucket, the thawing system of existing MDI generally only has one in order to melt the thawing pond of MDI, it normally is heated to 70 ℃ of left and right sides water through the water inlet in thawing pond toward melting to pass into to prepare in advance in the pond first, the MDI bucket that then will be loaded with MDI drops into from the charging aperture that melts the pond, after MDI in the MDI bucket melts the MDI bucket is taken out from melting in the pond, and open the discharge outlet of melting the pond and will melt water discharge in the pond.And in some operations of spinning, can produce steam condensate (SC), the temperature of these steam condensate (SC)s can satisfy the requirement of melting MDI, but normally this part steam condensate (SC) is directly drained as waste water at present, thereby causes the waste of resource.
[utility model content]
Technical problem to be solved in the utility model is to provide the thawing system of a kind of MDI, can melt the steam condensate (SC) that MDI requires and use satisfying, thereby avoid the waste of resource.
The utility model solves the problems of the technologies described above by the following technical programs: the thawing system of a kind of MDI, comprise thawing pond and a reclamation of condensate water pond in order to melt MDI, described thawing pond is provided with one first water inlet and a first row mouth of a river, and the top in this thawing pond is provided with one in order to drop into the charging aperture of MDI bucket; Described steam condensing water recovery pond is provided with one second water inlet and a connected entrance, and this connected entrance is connected by a pipeline with the first water inlet.
Further, the open-top in described thawing pond forms an open ports, and this open ports is described charging aperture.
Further, described steam condensing water recovery pond is case type.
The beneficial effect of the thawing system of a kind of MDI of the utility model is: the setting up of steam condensing water recovery pond, can get up in order to MDI is melted satisfying the reclamation of condensate water of melting the MDI requirement, thereby not only realized the recycling of steam condensate (SC), and need not the extra water of preparing to be heated to about 70 ℃ and melt MDI in order to water-bath, and then avoided the waste of resource, saved cost.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the schematic diagram of the thawing system of a kind of MDI of the utility model.
[specific embodiment]
See also Fig. 1, the thawing system 100 of a kind of MDI, comprise thawing pond 1 and a steam condensing water recovery pond 2 in order to melt MDI, described thawing pond 1 is provided with one first water inlet 11 and a first row mouth of a river 12, and the top in this thawing pond 1 is provided with a charging aperture 13 in order to drop into MDI bucket 200; Described steam condensing water recovery pond 2 is provided with one and allows meet and melt the second water inlet 21 and the connected entrance 22 that steam condensate (SC) that MDI requires enters, and this connected entrance 22 is connected by a pipeline 3 with the first water inlet 11; The second water inlet 21 is to introduce in the steam condensing water recovery pond 2 in order to will meet the steam condensate (SC) that melts the MDI requirement.In the present embodiment, the open-top that melts pond 1 forms an open ports, and this open ports is described charging aperture 13, and this design can drop into a plurality of MDI buckets 200 to melting simultaneously in the pond 1; For the temperature of the steam condensing water that better keeps compiling from each operation, this steam condensing water reclaims .2 and is designed to case type.
The utility model is when using, the switch of opening conduits 3 (not shown), make the steam condensate (SC) that collects the satisfied MDI of thawing requirement in the steam condensing water recovery pond 2 via connected entrance 22 flowing into pipeline 3 and finally via in the first water inlet 11 inflow thawing ponds 1, the MDI bucket 200 that will be loaded with afterwards MDI drops into from the charging aperture 13 that melts pond 1, after MDI in MDI bucket 200 melts with MDI bucket 200 from melting pond 1 interior taking-up, and open the first row mouth of a river 12 of melting pond 1 and will melt steam condensate (SC) discharge in the pond.
To sum up, the utility model can get up in order to MDI is melted satisfying the reclamation of condensate water of melting the MDI requirement, thereby not only realized the recycling of steam condensate (SC), and need not the extra water of preparing to be heated to about 70 ℃ and melt MDI in order to water-bath, and then avoided the waste of resource, saved cost.
