Abstract

The present invention discloses a method for producing semifinished rosin with natural fallen pine resin, which comprises the technology of dissolution, squeezing, cleaning and packaging. The present invention has the advantages of simple and feasible squeezing method, low investment, high work efficiency, no solvent loss in the process of processing. A recovery rate of effective components of natural pine resin can reach more than 90%.

Description

A kind of fallen rosin that utilizes is produced the rosin process of semi-finished

Technical field

The present invention relates to the method that a kind of rosin is produced, especially a kind of natural pine gum that utilizes is produced the rosin process of semi-finished.

Background technology

Pinus seeds such as pinus yunnanensis, slash pine, Pinus massoniana Lamb, pinus khasys are endangered by the disease worm, xylem sustains damage, wound can flow out a lot of rosin, these rosin accumulate over a long period, gather the pine tree root, in fallen rosin, the present invention collects this fallen rosin to be processed into the rosin work in-process this rosin for we.Fallen rosin is along with increasing duration of contact with air, and turps constantly volatilizees, the solid of yellowing, brown or black, and because of natural pine gum oxide content height, foreign matter content is big, and its physico-chemical property and fresh rosin have tangible difference.Can't successfully produce the rosin product so take conventional at present rosin production method.1, adds man-hour with ordinary method, become a kind of extreme heavy-gravity black jelly after oxidation rosin is heated in heat-processed, the ratio of this jelly is great, be deposited in device bottom, can influence heat conduction when producing with the method for dripping, lead to the consequence of burning the bottom of a pan, bring injury and loss can for when serious life, property.Promptly the sieve plate of equipment can be clung with steaming process production, line clogging very easily leads to security incident.2, because this jelly ventilation property is poor, when dissolving, adhere to each other with bark impurity silt again, can not separate with impurity easily, be difficult to filter, a lot of effective ingredients are arranged in the filter residue, product recovery rate is low, and yield only is raw-material 20%.Even 3 will process with ordinary method, its complex manufacturing, needing increases a large amount of dissolving, filter plant, and it is excessive to inject capital into.Solvent loss is also big, and product per ton consumes turps more than 0.3 ton.

Summary of the invention

The object of the present invention is to provide a kind of fallen rosin that utilizes to produce the rosin process of semi-finished, this method has solved processing fallen rosin dissolution filter difficulty, a difficult problem that the product yield is low, sought out simple and easy to do filter method, made natural pine gum make rosin and become a reality.

Technical scheme of the present invention is: a profit utilizes fallen rosin to produce the rosin process of semi-finished: 1, heating for dissolving: raw material and water are dropped into metal vessel internal heating to 100 ℃, block rosin is all dissolved; 2, squeezing: the material that dissolving is obtained is sent in the pressing device while hot and is squeezed, and fat hydraulic pressure is gone out, and removes the slag thing; 3, flushing: allow squeezing gained fat liquid from flowing in the container, add flushing with clean water, sewage is washed away, cool but the back the rosin work in-process, perhaps allow the fat liquid of squeezing gained flow in the container certainly, behind the venting sewage, add the turps of total amount 20% gradually, agitation and dilution just becomes the rosin work in-process, can be transported to rosin source mill and further be processed into the rosin finished product.

The invention has the advantages that: method is easy, drops into and economizes, instant effect; Because of what take is the pressure filtration method, and effective ingredient is residual few, and raw material per ton can obtain work in-process 0.4-0.6 ton; Rosin factory processes the rosin of this half-finished speed faster than the common artificial collection of processing.Present method is not used the dissolution with solvents natural pine gum, does not have the solvent loss problem.

Embodiment

A kind of fallen rosin that utilizes is produced the rosin process of semi-finished, and its step is: dissolving: get fallen rosin 50KG, drop in the iron pan, add water 30KG, be heated to 100 ℃ of degree, hand mixing is fully dissolved block rosin simultaneously; Squeezing: in the artificial pressing device of block form (similar bean curd pressing device), carry out, earlier with 60 orders to 120 purpose metallic sieves, fill up in pressing device, to dissolve the gained material packs in the screen cloth while hot, cover cover plate, boosting-rod puts wireline, with the pressurization of a thousand pieces of gold top, fat hydraulic pressure is squeezed out, to press dry degree of being.Purged and packed: fat liquid is sent in the receiver, constantly added flushing with clean water, get rid of dirt sewage, the cooling back is the rosin work in-process.Filter cake is handled: filter cake is struck diffusing, the turps that adds 5%-10% stirs, and row dissolving again, squeezing program reclaim the effective ingredient that residues in the filter cake.

Fallen rosin is along with increasing duration of contact with air, and turps constantly volatilizees, the solid of yellowing, brown or black, and because of natural pine gum oxide content height, foreign matter content is big, and its physico-chemical property and fresh rosin have tangible difference.Can't successfully produce the rosin product so take conventional at present rosin production method.1, adds man-hour with ordinary method, become a kind of extreme heavy-gravity black jelly after oxidation rosin is heated in heat-processed, the ratio of this jelly is great, be deposited in device bottom, can influence heat conduction when producing with the method for dripping, lead to the consequence of burning the bottom of a pan, bring injury and loss can for when serious life, property.Promptly the sieve plate of equipment can be clung with steaming process production, line clogging very easily leads to security incident.2, because this jelly ventilation property is poor, when dissolving, adhere to each other with bark impurity silt again, can not separate with impurity easily, be difficult to filter, a lot of effective ingredients are arranged in the filter residue, product recovery rate is low, and yield only is raw-material 20%.Even 3 will process with ordinary method, its complex manufacturing, needing increases a large amount of dissolving, filter plant, and it is excessive to inject capital into.Solvent loss is also big, and product per ton consumes turps more than 0.3 ton.

Claims

1, a kind of fallen rosin that utilizes is produced the rosin process of semi-finished, (1) heating for dissolving: raw material is dropped in the dissolving pan, add the clear water of total amount 1/3rd to 1/2nd, heating is dissolved rosin then; (2) squeeze and filter after natural pine gum adds water heating and dissolves, is sent into dissolved matter in the pressing device of band metallic sieve while hot, and fat hydraulic pressure is squeezed out; Directly take the way of squeeze and filter that fat hydraulic pressure is leached, remove waste residue, its pressing method is mechanical expression or artificial squeezing, (3) cleaning and cooling packing: the fat liquid that squeezing is come out flows to interior cleaning of container of clear water, and constantly add clear water, to get rid of mud, fat liquid is met cold water meeting accelerated solidification, the rosin work in-process, timely packing; (4) the slag thing is handled: remain the part effective ingredient after the slag thing press dry, add suitable turps or other organic solvent, once again heating for dissolving, squeezing, recovery effective ingredient.
