Abstract
The utility model discloses a device for recycling filtered alcohol in a washing and refining process for high-molecular polymers. The filter alcohol recovery device comprises a conveying device, a recycling barrel, an alcohol discharge pipeline, an alcohol discharge pipeline, a filter and an alcohol inlet pipeline, wherein the alcohol inlet pipeline is arranged at the top right end of the filter; the alcohol discharge pipe is arranged at the bottom left end of the filter; a filter screen is arranged at the bottom of the filter; the conveying device is arranged below the filter; and the recycling barrel is arranged on a conveying belt. By the device, the fine high-molecular polymers can be collected for recycling, so that the yield is improved, the loss is reduced, the cost is reduced, and the benefits of companies are improved.
Description
Technical field
The utility model relates to a kind of filtration alcohol recovery device, especially the filtration alcohol recovery device in high molecular polymer washing refining step.
Background technology
It is anionic macromolecular compounds that natural cellulose passes through a kind of good water solubility that makes after chemical modification that many high molecular polymers are arranged, and for example: Xylo-Mucine, it is the staple product of cellulose ethers.Usually take short velveteen or wooden oar as raw material, make with Mono Chloro Acetic Acid generation etherification reaction again through after sodium-hydroxide treatment.Because having many special propertys, as thickening, bonding, film forming, water holding, emulsification, suspension etc., and be used widely, be the Mierocrystalline cellulose kind that in the world today, use range is the widest, consumption is maximum.
Refining general minute four times of this family macromolecule polymkeric substance washing in preparation process of Xylo-Mucine, from raising successively to the 4th ethanol concn for the first time, to remove byproduct of reaction sodium-chlor, hydroxyethanoic acid sodium and the sodium glycolate in high molecular polymer, improve the purity of high molecular polymer.Rough high molecular polymer is refining through the washing that four ethanol concns raise successively, washes byproduct of reaction off, obtains highly purified high molecular polymer.In order to reduce the alcohol usage quantity, reduce costs, alcohol is carried out the pattern of applying mechanically in washing process, be that secondary washing is taken off spirituous solution after doing and got back in once washing and use, spirituous solution after three washings are taken off and done is got back in secondary washing and is used, the spirituous solution that four washings are taken off after doing is got back to use in three washings, and four times washing alcohol uses distilled spirit.In traditional washing refining step, after material is taken off alcohol through the screw rod dehydrator, some tiny materials run off with alcohol, enter in the alcohol storage tank, through rough Statistics, the high molecular polymer that ran off in alcohol in a day reaches 100kg(in siccative), long-term accumulation, not only cause the loss and waste of high molecular polymer, also can cause damage to equipment, directly have influence on the benefit situation of company; On the other hand, the alcohol storage tank needs irregularly cleaning, expend a large amount of manpower and materials, and the material that clears is more yellow, and quality reduces especially greatly, can only as technical grade product with very low sell at competitive, be very large loss.
Summary of the invention
Goal of the invention of the present utility model is in order to overcome the shortcoming of above-mentioned background technology, a kind of filtration alcohol recovery device is provided, and this device is by filtering the alcohol that takes off after doing, collected material again auto back be added in washing tank, reduce the loss of material, saved cost.
The technical solution of the utility model is: the filtration alcohol recovery device in a kind of high molecular polymer washing refining step, comprise that recycling bin and alcohol enter pipeline, it also comprises conveying belt, alcohol discharge tube, strainer, the upper right side of described strainer connects alcohol and enters pipeline, the lower-left end connects the alcohol discharge tube, the bottom is provided with filtering net, and described e Foerderanlage is arranged at below strainer, and described recycling bin is arranged on conveying belt.
Described strainer is that the bottom surface can be by the movable strainer in the bottom surface that weight is opened automatically.
The beneficial effects of the utility model are: filter alcohol recovery device by increase, tiny high molecular polymer is collected recovery, increased output, reduced loss, reduced cost, improved the benefit of company.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Wherein: 1, e Foerderanlage, 2, recycling bin, 3, the alcohol discharge tube, 4, strainer, 5, filtering net, 6, alcohol enters pipeline.
Embodiment
The present embodiment is the filtration alcohol recovery device in a kind of high molecular polymer washing refining step, it comprises that e Foerderanlage 1, recycling bin 2, alcohol discharge tube 3, strainer 4, alcohol enter pipeline 6, as shown in Figure 1, the upper right side of strainer 4 is connected to alcohol and enters pipeline 6, the lower-left termination has alcohol discharge tube 3, the bottom is provided with filtering net 5, and e Foerderanlage 1 is arranged at strainer 4 belows, and recycling bin 2 is arranged on conveying belt.
In Fig. 1, screw rod takes off alcohol after liquid and enters pipeline 6 by alcohol and enter in strainer 4, and due to the interception that filtering net 5 is arranged, tiny material is stayed on filtering net 5, and alcohol sees through filtering net 5 and enters in the alcohol withdrawing can via alcohol discharge tube 3.When strainer 4 is collected certain hour, when the inside deposits certain material, open the movable bottom surface of strainer 4, the material of collecting is put in recycling bin 2, recycling bin 2 is through the conveying of e Foerderanlage 1, the material of collecting is returned be added in washing tank, so circulation, effectively reduced the loss of material.
Claims (2)
1. the filtration alcohol recovery device in high molecular polymer washing refining step, comprise that recycling bin and alcohol enter pipeline, it is characterized in that it also comprises conveying belt, alcohol discharge tube, strainer, the upper right side of described strainer connects alcohol and enters pipeline, the lower-left end connects the alcohol discharge tube, the bottom is provided with filtering net, and described e Foerderanlage is arranged at below strainer, and described recycling bin is arranged on conveying belt.
2. the filtration alcohol recovery device in high molecular polymer washing refining step as claimed in claim 1, is characterized in that described strainer is that the bottom surface can be by the movable strainer in the bottom surface that weight is opened automatically.
