Abstract

The present invention discloses a method for producing agglomerate type cat sand. The present invention has the essential technical scheme that in the method for producing agglomerate type cat sand, attapulgite clay, sodium hydroxide, magnesium oxide, anhydrite and resin with high water absorption are mixed, stirred, extruded, dried in the sun, pulverized, granulated, dried in the sun, screened and packed into a finished product. The agglomerate type cat sand produced by the production method of the present invention keeps the advantages of ordinary cat sand, avoids the shortages of various kinds of cat sand, and has the advantages of no pollution, no dust, high intensity and low price. After a cat relieves the bowels on the cat sand, the cat sand tightly wraps urine and excrement and rapidly agglomerates urine and excrement into a whole. Therefore, the present invention has the characteristics of rapidly sucking and removing foreign odor, suppressing bacterial growth and keeping fresh ambient air, and is simultaneously good for hosts to clean the excrement.

Description

The production method of agglomerate type cat sand

Technical field:

The present invention relates to a kind of cat litter, be specifically related to a kind of production method of agglomerate type cat sand.

Background technology:

Like the people who keeps a cat more and more, in the process of raising cat, feel the thing of taking a lot of trouble most, be exactly the movement that all will handle cat every day, the past all is with behind the house earth or boiler ash sediment before the family, lived building now, what use is coal gas, can't go for the bedding and padding of this class, so cat litter has just been arranged on the market, be used for replacing the bedding and padding of this class, kept a cat very much fan's welcome, the kind of cat litter is a lot, has their own characteristics each.

Chinese patent Granted publication CN1155515C, Granted publication day is on June 30th, 2004, name is called " process for preparing granular pentonite ", " disclose a kind of process for preparing granular pentonite; its production stage is: select the oven dry of white wilkinite or dry; the yellow soda ash that adds 0.02-0.05 part in every part of white wilkinite by weight, put into Raymond machine and pulverize, be ground into 100-200 order soil powder; add the sodium silicate liquid of 0.03-0.06 part again; add 0.3-0.6 part water, stir, be pressed into cake; enter drying machine and dry with the extruding twin rollers, make moisture content≤10%, sieve then, the granule packaging of 0.8mm-4mm is got final product.The present invention is a kind of new production method, and adopts new prescription, and with the particle wilkinite good water absorption that the present invention produces, color and luster is pure white, and intensity is hard, and the caking performance is good, and impurity is few, and ash is low, can be used as cat litter and use, and also can be used as waterproof, impervious material ".

According to the documentation requirements of foregoing invention patent, through overtesting, " being pressed into cake with the extruding twin rollers, " also should pulverize, and just can reach " particle of 0.8mm-4mm "; The actual temperature of drying machine, do not set what are, according to test, when the temperature in the drying machine greater than more than 450 ℃, moisture is less than 2% o'clock, the particle wilkinite just can not " caking ", but be loose shape, therefore, clearly be not described in the above-mentioned patent document, just " making moisture content≤10% "; With the technology in the above-mentioned patent document, the cat litter of production, be a kind of irregular particle that corner angle are arranged, cat is easy to the claw of shouting pain cat when stool and urine.

Summary of the invention:

The objective of the invention is to overcome weak point in the prior art, provide that a kind of adhesive property is good, adsorptive power is strong, the production method of the intensity height after fast, the poly-group of poly-group speed, agglomerate type cat sand that the cleaning work amount is little.

The production method of agglomerate type cat sand is that attapulgite clay, sodium hydroxide, magnesium oxide, dehydrated gyp-and High hydrophilous resin are prepared burden, stirred, extruding, airing, grinding, granulation, airing, sub-sieve, are packaged as finished product.

Attapulgite clay be a kind of tool chain laminate structure contain Shuifu County's magnesium silicate clay mineral, the desirable chemical formula of attapulgite is: Mg ₅(H ₂O) ₄[Si ₄O ₁₀] ₂(OH) ₂, have unique crystalline structure, good adsorption performance and very strong water-absorbent.

Sodium hydroxide and magnesium oxide can improve the viscosity and the poly-group ability of cat litter, make a large amount of low-grade attapulgite clay ore deposits, have obtained utilization, greatly reduce production cost.

Dehydrated gyp-can improve the intensity of cat litter, and High hydrophilous resin is in order to strengthen the suction urine amount of cat litter, to reduce the actual usage quantity of cat litter, to reduce use cost.

The present invention is achieved by following technical proposals:

1, the production of agglomerate type cat sand batching is made up of flaky mixture and work in-process two portions, and the batching of the two is respectively:

(1), the batching of flaky mixture: attapulgite clay 40～80 weight %, water 15～55 weight %, sodium hydroxide 1～8 weight % and magnesium oxide 1～5 weight %.

(2), half-finished batching: flaky mixture 85～98 weight % after the airing, dehydrated gyp-1.5～14.5 weight % and High hydrophilous resin 0.05～2.0 weight %.

2, according to the batching of flaky mixture, earlier sodium hydroxide is added in the entry, after waiting to dissolve, evenly be added in attapulgite clay and the magnesian mixture, after 24～48 hours, complete moistening mixture, stir in the input stirrer, and push by extrusion machine, be squeezed into thickness less than 3 millimeters flaky mixture, send the airing of cement threshing ground.When flaky mixture moisture≤15%, just can enter powder-grinding process.

3, abrasive dust: according to half-finished batching, the flaky mixture after the airing, dehydrated gyp-and High hydrophilous resin are carried out abrasive dust jointly, the pulverulent mixture behind the abrasive dust, particle fineness≤0.074 millimeter.

4, granulation: with pulverulent mixture, carry out granulation on the input tablets press, granularity is controlled at 0.5～6 millimeter of .

5, airing: the particle of making should carry out airing, and after the particle airing, moisture answers≤12%.

6, sub-sieve and packing: should carry out sub-sieve after the particle airing, sieve goes in the cat litter to be packaged as finished product less than 0.5 millimeter comminuted powder.

Use production method of the present invention, the agglomerate type cat sand of producing has kept the advantage of common cat litter, has avoided the deficiency of all kinds of cat litters, and it is pollution-free, no dust, intensity height, price are quite cheap; Because this spherical shape cat litter, nontoxic, tasteless, as long as the religion cat once, the later stool and urine on cat litter that cat will be conscious, after the cat stool and urine, cat litter will tightly wrap up stool and urine, and poly-fast group is as a whole, therefore have quick absorption peculiar smell, bacteria growing inhibiting and maintenance environment characteristics with fresh air, also help owner simultaneously and clear up these ight soil.

Embodiment:

The invention will be further described below in conjunction with embodiment:

(1), the batching of flaky mixture: attapulgite clay 55 weight %, water 40 weight %, sodium hydroxide 3 weight % and magnesium oxide 2 weight %.

(2), half-finished batching: the flaky mixture 97 weight % after the airing, dehydrated gyp-2.5 weight % and High hydrophilous resin 0.5 weight %.

2, according to the batching of flaky mixture, elder generation is with the sodium hydroxide of 3 weight %, add in the water of 40 weight %, after waiting to dissolve, evenly be added in the magnesian mixture of the attapulgite clay of 55 weight % and 2 weight %, after 24 hours, with complete moistening mixture, stir in the input stirrer, and push by extrusion machine, be squeezed into thickness less than 3 millimeters flaky mixture, send the airing of cement threshing ground.When flaky mixture moisture≤15%, just can enter powder-grinding process.
