RU24689U1 - FLOW LINE FOR THE PROCESSING OF LEATHER AND FUR PRODUCTION WASTE - Google Patents

Abstract

A production line containing a raw material shredder, a raw material washing device, a cooking apparatus and a dryer installed in series and connected by vehicles, characterized in that the grinding device is made in the form of an impact apparatus equipped with a calibration sieve and a pneumatic system, the raw material washing device is made in in the form of a rake wool wash, the apparatus for hydrolysis is made in the form of a horizontal vacuum boiler.

Description

vacuum boiler. Using a horizontal type boiler allows to achieve a more uniform structure of the hydrolyzable mass, thereby increasing the area of interaction of the chemical reagent with raw materials and automate the hydrolysis process, the line additionally contains a reactor with

a mixer equipped with a recirculation system.

The line works as follows, (see fig.) Waste leather

and fur production is loaded into a grinder (1), which is a hammer mill with a rotor and a pneumatic system connected to it (4). The raw materials, falling into the grinding chamber, are exposed to the crusher hammers and are sifted through a sieve with a pneumatic system (4), transferred to a tank (2) for washing. Insufficiently crushed raw materials are retained on the sieve and subjected to repeated exposure with hammer grinders, which allows to obtain the necessary degree of grinding and then transferred to the tank (2) for washing.

The washed raw material, squeezed from excess moisture, is fed by a conveyor (10) to a storage tank (3) to prepare a hydrolyzable mixture, to which chemical materials are simultaneously fed. After thorough mixing to a homogeneous consistency, the hydrolyzable mixture is pumped (6) into the reactor (5) for hydrolysis.

In the reactor (5), the mass is hydrolyzed until a homogeneous pulp is obtained, which is then pumped (10) to the hydrolyzate collector (7). The hydrolyzate under pressure enters the drying and crushing unit (9) where it is dried to a powder with a moisture content of 10-12%. Excess hydrolyzate is returned to the collection tank (7). The hydrolyzate in the collector exfoliates during storage, which leads to heterogeneity of the final product. The hydrolyzate homogeneity is achieved through the use of a steel enameled reactor with a stirrer.

Comparative analysis with the prototype shows that the proposed line differs from the prototype in the presence of additional devices that allow the processing of both waste from leather production and waste from fur to produce protein hydrolysates, i.e. the line is new with respect to the prototype.

The authors did not identify a line for the processing of leather waste containing a combination of features indicated in the formula. Thus, the authors believe that the proposed line meets the criterion of "significant differences in the totality of features.
