Description

Polluted soil cultivation apparatus with a crushing device

The present invention relates to a contaminated soil cultivation device equipped with a crushing addition, and more specifically, a shear cutting portion consisting of a cutting blade attached to a crushing addition is attached to a backhoe to provide a crushing addition to cultivate a large amount of contaminated soil within a short period of time. To a contaminated soil tillage device.

In general, oil is introduced into the soil and contaminated due to oil leakage or spillage due to aging and damage of the underground oil storage tanks in gas stations, military units or factory areas. Since the growth of animals and plants is not normal, farming is carried out.

Such cultivation usually involves excavating and transporting soil from contaminated sites, spreading the contaminated soil on the surface to a certain thickness on the surface, and promoting aerobic biodegradation by nutrients (nitrogen, phosphorus), moisture, and oxygen to promote and decompose. Process, that is, by placing the contaminated soil on the surface and turning it upside down on a regular basis to control the soil characteristics such as water content, oxygen content, nutrients (nitrogen, phosphorus) and pH to supply air and optimize the decomposition rate of the contaminants. do.

In the process of cultivating contaminated soil, first, biodegradation of contaminated soil is applied to highly volatile substances such as gasoline of oil and polymer hydrocarbons (diesel fuel, oil sludge, coal contaminated soil, insecticide, etc.). As a limiting factor, various factors include the following.

-Large space required.

-It doesn't have proper condition for decomposition of pollutants, so it takes a lot of time to completely remove materials that are difficult to decompose.

-Degradation of microbial activity occurs due to the effect of winter temperature.

-The energy consumption of the flipping process is high.

In the conventional technology of such soil contaminated soil, biologically purified by tillage treatment using a so-called tractor which supplies oxygen and injects nutrient solution by laying the soil contaminated in the soil of the contaminated soil thinly to about 30cm and turning it in a rotary manner. However, the efficiency of small-scale purification is high, but the efficiency and economic efficiency of large-scale purification are falling. Such a cultivation treatment requires a large site for thinning contaminated soil, and a mechanical device for cultivation and a long time work. The problem is that it takes time.

In another conventional art, in order to treat a large amount of contaminated soil by cultivation using a backhoe, the soil height of the soil is laid within 30 to 80 cm, and then the backhoe is inverted. There are problems in various purification efficiency and economical efficiency as the flipping work is carried out by excavating and sprinkling the piled soil by using a bucket and a manure bucket.

In addition, the following problems occur in the tillage process using the backhoe.

-Large capacity polluted soil can be turned over, but mechanical power costs for tillage are high, and labor loads of machinery and auxiliary personnel are higher than tillage with the tractor.

-There is a need for manpower to periodically spray microorganisms and nutrients (nitrogen and phosphorus) during farming operations.

-As the water content in the contaminated soil increases due to the periodic tilling, the soils fall into the cake shape of the bucket standard during the tilling, and thus, it is not possible to obtain the shredding effect of subdividing each soil particle by the shredding as in the present invention.

-A blind spot of purification occurs. The high soil height of contaminated soil does not cause the soil to be crushed smoothly, and the purification efficiency decreases as the microorganism and oxygen supply are lowered into the contaminants (oil) between the particles and the soil. .

-Difficult to mix microorganisms and nutrients in contaminated soil

The so-called rotary grinding type tillage device, which is applied to the bucket type rotary type tillage device, is used to supplement the problems of tillage of contaminated soil, and this device is a food grinder application device for mixing or simultaneously conveying materials. As the screw rotates, the polluted soil crushed through the rear sieve is used on the principle, but this also has the following problems.

-When crushing the solid soil of contaminated soil, the crushing equipment of rotary milling method has a lot of problems such as foreign materials, stones, vinyl, etc. between screw, and the flipping effect is insignificant.

-In particular, the degree of crushing has been improved compared to the conventional tractors and backhoe buckets, but there are some difficulties in the field application to invert or crush a large amount of contaminated soil by an excavation type.

Since the purpose of the cultivation device for cultivating contaminated soil as described above is to cultivate 0 to 50 cm deep in the ground, cultivation within a depth of 50 to 100 cm for more efficient and economical cultivation of contaminated soil. However, there is no tillage device used for this purpose.

The present invention has been made to improve the above-mentioned problems, the purpose of the high temperature steam that can blow high temperature steam while having a length longer to be able to cultivate contaminated soil of more than 1m deep underground Attaching a shear cut portion formed by a cutting blade attached to the injection pipe to the backhoe, to provide a contaminated soil cultivation device that facilitates the flipping and crushing of soil contaminated by the shear cut portion.

Another purpose is to attach the rear end crushing part together with the shear cutting part to the backhoe with the mixing blade and the crushing blade arranged at regular intervals up and down, and to lift the contaminated soil of more than 1m underground to the upper soil It is to provide a contaminated soil tillage device that facilitates mixing and crushing operations.

In order to achieve the object as described above, the contaminated soil tillage device equipped with a crushing addition according to the present invention is attached to the backhoe (17) by the backhoe connecting link (3) to cultivate the contaminated soil, at regular intervals A plurality of cutting blades 5 disposed downward and connected to each other by a connecting bar 18 at an upper end thereof; And a plurality of shredding weights (8) connected to the cutting blades (5) and having a plurality of wings (8b) attached at regular intervals along the outer circumferential surface thereof. It characterized in that it comprises a shear cut portion (1) to be attached.

In addition, the crushing weight 8 is connected at regular intervals up and down at the lower end of each cutting blade 5, the bolt hole (H) penetrated at regular intervals up and down at the top of each cutting blade (5) (H) It is preferable that the height of each cutting blade 5 can be adjusted by the following.

In addition, the shear cut section 1 includes a plurality of hot steam spray pipes 6 attached to the front of each of the cutting blades 5 and bent from the bottom to the front, respectively; And hot steam nozzles 7 respectively connected to upper ends of the hot steam spray pipes 6, respectively.
