Problems solved by technology

In the production process, the low rubber content latex produced by washing equipment or the low rubber content latex (such as latex content <5%, referred to as thin latex) whose rubber content does not meet the production needs, and the latex waste liquid whose stability is seriously reduced, are usually processed through Discharge after treatment, which increases the cost of wastewater treatment and also causes waste

Embodiment 1

[0015] Embodiment 1 of the present invention: as figure 1 As shown, the device structure includes a settling tank 1 for settling latex waste liquid and plant fiber waste residue, a press dryer 2 for pressing and drying the sediment, and a hot press 3 for hot pressing and Vulcanized vulcanization tank4.

[0016] Install plant fiber adding device 6 and latex waste liquid delivery port 8 on settling tank 1, settling agent conveying box 5 is used to add settling agent, and stirring paddle 7 is installed in settling tank 1, latex waste liquid and plant fiber waste residue Stir evenly, set a discharge port 9 at the bottom of the settling tank 1, and discharge the raffinate.

[0017] The molding dryer 2 structure includes a conveyor belt 10 on which a roller 11 (roller) for molding is installed, and a drying device 12 is installed behind the roller 11 . The drying device 12 is composed of a hot air blower installed below the conveyor belt 10 , a hot air distribution plate, and a de...

Embodiment 2

[0023] Embodiment 2 of the present invention: device is identical with embodiment 1, and during settling, the settling agent that adopts is hydrochloric acid, polyacrylamide, and calcium nitrate, uses industrial hydrochloric acid to adjust the liquid pH value of settling tank to 6, by weight, Mix 1 part of polyacrylamide with 2 parts of calcium nitrate, add the mixture to the settling tank, and stir until gelation begins to appear in the settling tank, stop adding the settling agent.

[0024] After testing, the parameters of each section are as follows, and the effect is better: the drying temperature is kept at 80-100°C, and the moisture in the dried sheet is 14-16%. The temperature during hot pressing is 100-110°C. The vulcanization temperature is 110-115°C, the vulcanization time is 20-40 minutes, and the vulcanization pressure is 0.2-0.35MPa.

Abstract

The invention discloses a method and device for producing a plant fiber straw mattress substrate. The method is characterized by comprising the steps of: feeding latex liquid waste and plant fiber waste residues into a sedimentation pond, adding a settling agent into the sedimentation pond after the mixture is uniformly stirred, collecting, pressing and drying obtained deposits to obtain sheets, performing hot pressing on at least one sheet to obtain the substrate with the required thickness, and vulcanizing the substrate. By means of the method and device for producing the plant fiber straw mattress substrate, the latex liquid waste and the plant fiber waste residues, which cannot be utilized with the traditional production process, are reprocessed, thereby the emission of waste materials and liquid waste is reduced, the use values of plant fibers and latex are improved, and the purpose of better environmental friendliness is achieved. Moreover, a new product is obtained and the production cost is reduced.

Description

technical field [0001] The invention relates to a method and a device for producing a plant fiber straw mat base material, in particular to a method and a device for making a grass mat base material by using latex waste liquid and plant fiber waste residue. Background technique [0002] Chinese patent 031171788 discloses a kind of palm fiber lawn cultivation substrate, utilizes natural palm fiber silk and latex to make lawn cultivation substrate. In the production process of plant fiber elastic materials, plant fiber filaments (mountain palm, oil palm, coconut shell, hemp, etc.) will produce 10-15% plant fiber waste residue after decomposition, loosening, flakes and other processes, and the length is less than 5 cm , does not meet the length requirements for recycling again, and there are still latex pieces on the waste residue, these plant fibers are generally discarded in the existing production. In the production process, the low rubber content latex produced by washing ...
