Embodiment 1

[0022] Such as figure 1 The degreasing and recycling system for leather shoe waste shown in the figure includes a waste leather collection bin connected by a conveyor belt, a screening machine, a separation tank, a cleaning tank, a filter tank, an acid-base soaking tank, a softening tank, a dehydrator, a tearing The mill, and the immersion tank connected with the tearing mill, also includes a cutting machine connected with the screening machine, wherein the leather waste in the waste leather collection bin is transported to the screening machine, and the large leather waste in the leather waste is transported to the screening machine by the screening machine Screened out, the screened large pieces of leather are transported to the cutting machine to cut into small particles of 1-2cm, and then transported to the cleaning pool for soaking for 2 hours and cleaning 3 times; after removing the large leather, other leather garbage is transported to the separation pool Add water and ...

Embodiment 2

[0025] Such as figure 1 Shown is a system for degreasing and regenerating leather shoe waste. On the basis of Example 1, the sizing system includes a molding frame and a press, wherein the leather fiber mixture is flattened in the molding frame for molding, and then the press is started. Apply pressure to the leather fiber mixture in the molding frame for 8 minutes to make the leather molded, then take it out and transport it to a drying room for drying for 24 hours, so that the water content in the regenerated leather is controlled at 12%.

Embodiment 3

[0027] Such as figure 1 A kind of degreasing regeneration recovery system of leather shoe waste shown, on the basis of embodiment 1, the pressure that described press machine is applied to the leather fiber mixture in the molding frame is gradually increased from 25Mpa to 150Mpa, so that the regenerated leather can Press down firmly.

Abstract

The invention discloses an oil-removing, regenerating and recycling system for leather shoe waste. The oil-removing, regenerating and recycling system comprises a waste leather collecting bin, a screening machine, a separating tank, a cleaning tank, a filter tank, an acid-base soaking tank, a softening tank, a dehydrator, a tearing-grinding machine and a soaking tank, which are connected through a conveyor belt, and further comprises a dyeing tank, a paddle and a ball mill, which are sequentially connected with the soaking tank through the conveyor belt as well as a shaping system, a polishing machine and a drying room, wherein the soaking tank is connected with the tearing-grinding machine. Existing equipment is integrated to form a system which is specially used for recycling waste leather of a leather shoes factory, can solve the problem that regenerated leather is not liable to manufacture and form, and finally prepares the recycled leather waste into useable regenerated leather, so that leather leftover materials and the like generated by the shoes factory are sufficiently recycled, and therefore, the oil-removing, regenerating and recycling system is environmentally friendly, and saves economic cost.

Description

technical field [0001] The invention relates to the field of waste material recovery and regeneration, in particular to a system for degreasing, regeneration and recovery of leather shoe waste. Background technique [0002] With the continuous improvement of people's living standards, the scope of use of leather products is becoming wider and wider, and the number of uses is increasing year by year. Leather has the properties of toughness, wear resistance, good elasticity, and strong tensile force. There are two common types: raw hide and leather (cooked leather). made. Waste leather is rich in resources, with many varieties and great uses. Good recycling will play a certain role in supporting industrial and agricultural production. In the process of making leather shoes, shoe factories always produce a large amount of leather slag, broken leather, trimming scraps, and leather shavings. The amount of all kinds of discarded leather products is astonishing. If a large amoun...
