Abstract

The present invention relates to a method of preparing plant moisture fertilizer maintaining particles through waste clay and waste attapulgite clay, which belongs to the technical field of obsolete resources for reuse. The present invention is characterized in that after waste clay and waste attapulgite clay which are generated in the process of vegetable oil refining are mixed with pore-expanding agents, adhesive is added and stirred to agglomerate, and the particle with the required size and shape is prepared and obtained through drying and baking. The moisture fertilizer maintaining particle prepared by the method has porous structure and favorable moisture fertilizer maintaining performance; the appearance of the particle forms hoary or the required color is made through adding paint; the plant moisture fertilizer maintaining particle can replace a cobble to be used for culturing hydrophilous plants of daffodil, etc., and can also be covered on the root soil of soil culture plants to have the functions of moisture maintainability, water and soil erosion and beautify,; because the plant moisture fertilizer maintaining particle is prepared by obsolete industrial waste residues, the cost is low and the process is simple.

Description

Prepare the method that plant moisturizing is protected fertile particle with useless carclazyte or useless recessed soil

Technical field

The present invention prepares the method that plant moisturizing is protected fertile particle with useless carclazyte or useless recessed soil, belongs to the technical field that waste resource utilizes again.

Background technology

In the refining process of vegetable oil, needs use atlapulgite or active recessed soil decolours, deodorization, therefore, useless carclazyte that the meeting output is a large amount of or useless recessed soil, at present, the processing method of useless carclazyte or useless recessed soil mainly be direct landfill or reclaim Residual oil after landfill or burn after abandon it, environment is polluted.

The solid root of the particularly ornamental watercress growth of watercress is many at present with particles such as stone or cobbles, though stone or cobble tool sight suction nutrient preserving capability extreme difference, therefore, plant need often be watered; In addition soil is planted ornamental plants and its root exposed soil of urban greenery plants also need cover one deck brick class particle usually, and the one, increase that it is attractive in appearance, the 2nd, avoid stirring up a cloud of dust and water and soil loss.

Summary of the invention

The objective of the invention is to: provide useless carclazyte of a kind of usefulness or useless recessed soil to prepare the method that plant moisturizing is protected fertile particle, utilize the useless carclazyte or the useless recessed soil that produce in the plant refining process to produce the moisture-keeping, fertilizer-keeping particle, reduce production costs the protection environment for raw material.

The present invention prepare plant moisturizing with useless carclazyte or useless recessed soil and protects the method for fertile particle and be: Residual oil extrudes extremely＜5% in will give up carclazyte or the useless recessed soil, breaing up back adding expanding agent stirs, adding binding agent stirs agglomerating, can in binding agent, add pigment if desired, make the particle of required size and shape, take out the nature cooling after drying, the roasting and obtain; The reaming dosage that adds is the 0.5%-1% of useless carclazyte or useless recessed native weight; Expanding agent can be carbonic hydroammonium or carboxymethyl cellulose; The addition of binding agent is the 1%-3% of useless carclazyte or useless recessed native weight; Binding agent can be water or waterglass; Bake out temperature is 80 ℃-120 ℃; Sintering temperature is 600 ℃-900 ℃; Roasting time is 2-3 hour.

The invention has the advantages that:

1, utilizing industrial residue---the useless carclazyte or the useless recessed soil that produce in the vegetable oil refining process are primary raw material, and raw material is easy to get, and cost is low, and the protection environment.

2, Zhi Bei technology and equipment require simple.

3, can be according to different purposes, different needs are made different sizes, shape and color.

4, this plant moisturizing is protected fertile particle and is had loose structure and good suction fertilizer-sucting performance, and the liquid manure sustained release performance.

Embodiment

Example 1: reduce to below 5% with filter press or the vacuum filter carclazyte residual oil content that will give up, soil is broken up and added after 0.5% expanding agent carbonic hydroammonium is stirred well to evenly with agitator, insert forming machine and add 1% binding agent water, make required size shape particle by necessary requirement, place warm air drier after 80 ℃ of oven dry particle, place roaster in 600 ℃ of roastings 2 hours again, naturally cooling.

Example 2: reduce to below 5% with filter press or the vacuum filter carclazyte residual oil content that will give up, soil is broken up and added after 1% expanding agent carbonic hydroammonium is stirred well to evenly with agitator, insert forming machine and add 3% binding agent water, make required size shape particle by necessary requirement, place warm air drier after 80 ℃ of oven dry particle, place roaster in 600 ℃ of roastings 3 hours again, naturally cooling.

Example 3: reduce to below 5% with filter press or the vacuum filter carclazyte residual oil content that will give up, soil is broken up and added after 0.5% expanding agent carboxymethyl cellulose is stirred well to evenly with agitator, insert forming machine and add 1% water glass of binder, make required size shape particle by necessary requirement, place warm air drier after 80 ℃ of oven dry particle, place roaster after 2 hours, to cool off naturally again in 600 ℃ of roastings.

Example 4: reduce to below 5% with filter press or the vacuum filter carclazyte residual oil content that will give up, soil is broken up and added after 1% expanding agent carboxymethyl cellulose is stirred well to evenly with agitator, insert forming machine and add 3% water glass of binder, make required size shape particle by necessary requirement, place warm air drier after 120 ℃ of oven dry particle, place roaster after 3 hours, to cool off naturally again in 900 ℃ of roastings.

Claims

1, prepares the method that plant moisturizing is protected fertile particle with useless carclazyte or useless recessed soil, it is characterized in that: the useless carclazyte or the useless recessed soil that adopt vegetable oil refining to produce evenly mix with expanding agent, add binding agent, make required form and size particles, roasting makes after the drying; The reaming dosage that adds is the 0.5%-1% of useless carclazyte or useless recessed native weight; Expanding agent is carbonic hydroammonium or carboxymethyl cellulose; The addition of binding agent is the 1%-3% of useless carclazyte or useless recessed native weight; Binding agent is water or waterglass; Bake out temperature is 80 ℃-120 ℃; Sintering temperature is 600 ℃-900 ℃; Roasting time is 2-3 hour; Residual oil content is reduced to below 5% in useless carclazyte or the useless recessed soil.
