Abstract
A kind of solid initiator feeding device, belongs to technical field of chemical engineering.Including batching kettle and feed pot, described feed pot is arranged on the top of batching kettle, and the bottom of feed pot connects batching kettle by charging valve, and described feed pot is provided above nitrogen intake valve at sidepiece, and feed pot is at top installation of relief valve.Can prevent when adding solid initiator in batching kettle air from entering batching kettle, thus be effective to ensure that safety in production, it is ensured that product quality.
Description
Technical field
This utility model belongs to technical field of chemical engineering, is specifically related to a kind of solid initiator feeding device.
Background technology
Tri-n-butyl phosphine is a kind of organic phosphine compound, and its coordination compound formed with many transition metals is a very important class catalyst, and in polyurethane industrial, tri-n-butyl phosphine is the excellent catalyst of synthesis isocyanate trimerization reaction.Need to add in batching kettle in midway solid initiator during tri-n-butyl phosphine reaction, and need in batching kettle to completely cut off air.Accordingly, it would be desirable to consider how to join in batching kettle by pressed powder initiator in the case of not introducing air, to complete charging process.
In view of above-mentioned prior art, the applicant has made useful design, and technical scheme described below produces under this background.
Summary of the invention
The purpose of this utility model is to provide a kind of solid initiator feeding device, is avoided that when adding solid initiator to batching kettle and brings air into, it is thus possible to safety in production is effectively ensured.
The purpose of this utility model is such to reach, a kind of solid initiator feeding device, it is characterized in that: include batching kettle and feed pot, described feed pot is arranged on the top of batching kettle, the bottom of feed pot connects batching kettle by charging valve, described feed pot is provided above nitrogen intake valve at sidepiece, and feed pot is at top installation of relief valve.
In a specific embodiment of the present utility model, the bottom of described batching kettle is provided with outlet valve.
This utility model is owing to have employed said structure, compared with prior art, has the beneficial effect that and can prevent when adding solid initiator in batching kettle air from entering batching kettle, thus be effective to ensure that safety in production, it is ensured that product quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. batching kettle；2. feed pot；3. charging valve；4. nitrogen intake valve；5. atmospheric valve；6. outlet valve.
Detailed description of the invention
Detailed description of the invention of the present utility model is described in detail by applicant by combining accompanying drawing below; but applicant is not the restriction to technical scheme to the description of embodiment, any changing in the form rather than substance according to this utility model design all should be considered as protection domain of the present utility model.
Referring to Fig. 1, this utility model relates to a kind of solid initiator feeding device, and including batching kettle 1 and feed pot 2, the bottom of described batching kettle 1 is provided with outlet valve 6.Described feed pot 2 is arranged on the top of batching kettle 1, and the bottom of feed pot 2 connects batching kettle 1 by charging valve 3.Described feed pot 2 is provided above nitrogen intake valve 4 at sidepiece, and described nitrogen intake valve 4 connects Nitrogen source gases, and feed pot 2 is at top installation of relief valve 5.
Please continue to refer to Fig. 1, this utility model is in use, first pass through nitrogen intake valve 4 and atmospheric valve 5 nitrogen injection in feed pot 2, make the air in feed pot 2 be excluded, then open inlet valve 3, the raw material in feed pot 2 is sent in batching kettle 1 and reacts, so, avoid to bring air into when adding solid initiator in batching kettle 1, thus be effective to ensure that safety in production, and guarantee product quality.
