Abstract
The utility model provides a kind of production system of maleic anhydride grafts, avoids the situation that maleic anhydride adheres to when mixing with raw polyolefin in this system.To achieve these goals, the technical scheme that the utility model adopts is: a kind of production system of maleic anhydride grafts, comprise forcing machine, the heating kettle of fusing maleic anhydride is also comprised in described system, in described heating kettle, the outlet of maleic anhydride material communicates with the charging opening of described forcing machine, and the pipeline that described heating kettle is communicated with forcing machine is provided with the pump injected by melting maleic anhydride in forcing machine.This technical scheme has set up the heating kettle in advance maleic anhydride material being carried out to heat fused, the maleic anhydride of following melting by pump exert pressure be injected in forcing machine with polyolefine mixed melting, reactive grafting, wire drawing pelletizing fully in an extruder, finally obtained product.Solve the problem of material sticks on pipeline like this, avoid the waste of material, shorten maleic anhydride material and polyolefinic mixing time; Also maintain material proportion precision simultaneously, avoid the impact on quality product.
Description
Technical field
The utility model relates to chemical production technical field, the production system of its specifically a kind of maleic anhydride grafts.
Background technology
Maleic anhydride grafts be a kind of maleic anhydride with polyolefine after mixing machine mixes, by the product that forcing machine melting, reactive grafting, wire drawing pelletizing are obtained.Often going wrong in this production process: maleic anhydride, easily sticking on equipment, pipeline when mixing machine mixes with raw polyolefin, causes line clogging, causing material proportion amount to be forbidden on the other hand, affecting quality product.
Summary of the invention
The utility model provides a kind of production system of maleic anhydride grafts, avoids the situation that maleic anhydride adheres to when mixing with raw polyolefin in this system.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of production system of maleic anhydride grafts, comprise forcing machine, it is characterized in that: the heating kettle also comprising fusing maleic anhydride in described system, in described heating kettle, the outlet of maleic anhydride material communicates with the charging opening of described forcing machine, and the pipeline that described heating kettle is communicated with forcing machine is provided with the pump injected by melting maleic anhydride in forcing machine.
As shown from the above technical solution, set up the heating kettle in advance maleic anhydride material being carried out to heat fused, the maleic anhydride of following melting by pump exert pressure be injected in forcing machine with polyolefine mixed melting, reactive grafting, wire drawing pelletizing fully in an extruder, finally obtained product.Solve the problem of material sticks on pipeline like this, avoid the waste of material, shorten maleic anhydride material and polyolefinic mixing time; Also maintain material proportion precision simultaneously, avoid the impact on quality product.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
A kind of production system of maleic anhydride grafts, comprise forcing machine 10, the heating kettle 20 of fusing maleic anhydride is also comprised in described system, in described heating kettle 20, the outlet 21 of maleic anhydride material communicates with the charging opening 11 of described forcing machine 10, and the pipeline that described heating kettle 20 is communicated with forcing machine 10 is provided with the pump 30 injected by melting maleic anhydride in forcing machine 10.As shown from the above technical solution, set up the heating kettle 20 in advance maleic anhydride material being carried out to heat fused, the physical property of maleic anhydride will be melted when being heated to about about 60 DEG C, once immediately will crystallization lower than this temperature, so heating can make following maleic anhydride material and polyolefine abundant mixed melting in an extruder more easily more save time, due to its poor fluidity of maleic anhydride of melting, just can be sent in forcing machine 10 so pump 30 must be used to implement certain pressure to it, the maleic anhydride of following melting and polyolefine will mixed meltings fully in forcing machine 10, reactive grafting, wire drawing pelletizing, finally obtained product.Solve the problem of material sticks on pipeline like this, avoid the waste of material, shorten maleic anhydride material and polyolefinic mixing time; Also maintain material proportion precision simultaneously, avoid the impact on quality product.
Preferably, ram pump selected by described pump 30.Because the maleic anhydride of melting not only can be sent into forcing machine 10 by ram pump, but also quantitatively can regulate supply to the maleic anhydride of melting, ensure that the accurate proportioning of material.
Concrete heating kettle 20 structure as shown in the figure, be provided with in the still chamber of described heating kettle 20 and be connected and the stirring rake 22 making it stir with motor, the inwall 23 of described heating kettle 20 and outer wall 24 enclose the folder chamber 25 being formed and have gap, the outer wall 24 of described heating kettle 20 is provided with for thermal medium by pressing from both sides import 26 and the outlet 27 in chamber 25, and the outlet 21 of described maleic anhydride material is positioned at the bottom of heating kettle.The dog-house 28 of raw material maleic anhydride through heating kettle 20 top drops into, and can close this dog-house, and it is healthy to enter in operating environment injury after distilling to avoid maleic anhydride, then maleic anhydride through heating kettle 20 heated and stirred until molten state.Concrete operational condition is: logical 60 DEG C of hot water are in folder chamber 25, open the dog-house 28 of heating kettle 20, weighted maleic anhydride is dropped in still, open the agitator on heating kettle 20, rotating speed controls at 20 ~ 30Hz, is melted by maleic anhydride, opens the other feed valve 50 of ram pump 30, adjust variable according to manufacturing technique requirent, liquid maleic anhydride is evenly injected forcing machine 10.
The pipeline that heating kettle 20 is communicated with forcing machine 10 is provided with thermal insulation layer 40.Due to the physical property of maleic anhydride, its cooling is easy to crystallization, so set up its main object of thermal insulation layer here to prevent crystallization exactly, can be injected in forcing machine 10 smoothly react to make the maleic anhydride of melting by ram pump 30.
