Abstract

Patent of the present invention discloses drum-type soil heavy metal and elutes continuous running gear, and described device is by roller(1), native liquid collecting region(2), bucket(3)With swash plate Disengagement zone(4)Four parts form;Roller(1)5 meters of length, 10 ° of inclination angle, 1 meter of diameter, corrosion protective lining is inside made, and angular thread shape structure is installed, 0.95 meter of the big footpath of angular thread shape structure, 0.35 meter of path, 0.25 meter of pitch are installed;Native liquid collecting region(2)1 meter of length, 1 meter of width are deep 0.5 meter;Bucket(3)60 ° of inclination angle, it is deep 0.5 meter;Swash plate Disengagement zone(4)It is long 1 meter, wide 1 meter, deep 0.4 meter, 60 ° of inclination angle.The device has the following advantages that:The continuous operation of heavy metal-polluted soil elution is realized, and elution time, unit interval soil elution amount can be adjusted by drum rotation speed, can meet the operating condition requirement that different pollution type heavy metal-polluted soils quickly elute;Device integrally realizes native liquid and is automatically separated, and facilitates the recovery of cleaning soil and subsequently focusing on rich in heavy metal washing lotion.

Description

Drum-type soil heavy metal elutes continuous running gear
Technical field
Patent of the present invention belongs to heavy-metal contaminated soil chemical remediation technology field, and in particular to a kind of drum-type soil weight Metal washing device, the showering of the severe that is particularly suitable for use in heavy-metal contaminated soil.
Background technology
Soil is the important foundation of natural environment for the survival of mankind and agricultural production.Since the 1920s, Due to industrial expansion, the yield of metal substantially increases, and resulting heavy metal problem of environmental pollution also occurs therewith, many Country starts to be faced with the problem of soil pollution seriously hinders agricultural production.It is reported that China by heavy metal pollution arable land Up to 300,000,000 mu, and heavy metal pollution occurred industry to agricultural transfer, city to transfer of rural, earth's surface to underground shift, upstream to Downstream is shifted, quick-fried into sudden, linksystem, regionality is polluted by polluting progressively accumulation from water and soil pollution to food chain tra nsfer The situation of hair.Therefore, the heavy metal pollution of soil Treatment process for seeking economical and efficient is extremely urgent.
At present, the restorative procedure of heavy metal pollution of soil mainly have peripheral doses, chemical remediation and it is biological prosthetic the methods of. Compared with other restorative procedures, chemical repair method has the advantages that stable treatment effect, cycle are short, improvement is thorough, especially suitable Quick improvement for serious pollution soil.A kind of patent document CN102225425A " elution of restoration of soil polluted by heavy metal Method " reports a kind of chemical repair method of heavy-metal contaminated soil, however, this method is also rested in laboratory stage; Patent document CN101704017A " methods and its device of extracting heavy metal ions from soil " propose it is a kind of for cadmium, Chromium, copper, mercury, the Extraction of Heavy Metals method of lead and other elements contaminated soil, but this method is similarly in laboratory stage.For soil The present situation of outburst is concentrated in heavy metal pollution, and the heavy metal-polluted soil elution technique for developing adaptation production requirement is extremely important.
The content of the invention
The defects of existing for prior art and deficiency, propose a kind of drum-type soil weight to be integrated with production technology demand Metal washing device.The device can realize the continuous operation of heavy metal-polluted soil elution, simultaneously, it is possible to achieve native liquid divides automatically From, and then reclaim the cleaning soil after elution.
The technical scheme of patent of invention is as follows:
Drum-type soil heavy metal elutes continuous running gear, it is characterised in that:Described device is by roller(1), native liquid receives Ji Qu(2), bucket(3)With swash plate Disengagement zone(4)Four parts form;Roller(1)5 meters of length, 10 ° of inclination angle, 1 meter of diameter, inside do Corrosion protective lining, and angular thread shape structure is installed, 0.95 meter of the big footpath of angular thread shape structure, 0.35 meter of path, pitch are installed 0.25 meter;Native liquid collecting region(2)1 meter of length, 1 meter of width are deep 0.5 meter;Bucket(3)60 ° of inclination angle, it is deep 0.5 meter;Swash plate Disengagement zone (4)It is long 1 meter, wide 1 meter, deep 0.4 meter, 60 ° of inclination angle.
The major advantage of patent of the present invention is as follows:(1), realize heavy metal-polluted soil elution continuous operation, and elute when Between, unit interval soil elution amount can be adjusted by drum rotation speed, can meet that different pollution type heavy metal-polluted soils are quick The operating condition requirement of elution;(2), device integrally realize native liquid and be automatically separated, facilitate the recovery of cleaning soil and be rich in The follow-up of heavy metal washing lotion focuses on.
Brief description of the drawings
Fig. 1 is the overall schematic of the device;Fig. 2 is roller A-A profiles.
In figure:1-roller;2-native liquid collecting region;3-bucket;4-swash plate Disengagement zone;5-belt driver hinged-support.
Embodiment
Referring to Fig. 1-Fig. 2, the device is by roller(1), native liquid collecting region(2), bucket(3)With swash plate Disengagement zone(4)Four It is grouped into.First, 5 meters of a segment length, the irony tubing of 1 meter of diameter are chosen, and corrosion protective lining is coated with tubing inner homogeneous, it Angular thread shape structure is installed inside tubing afterwards, 0.95 meter of the big footpath of angular thread shape structure, 0.35 meter of path, pitch are installed 0.25 meter;Secondly, the roller that will be processed(1)It is fixed on the hinged-support of belt driver, and make it that mounted angle is 10 °; Again, long 2 meters, wide 1 meter, deep 0.5 meter cuboid is built below roller end, afterwards, the cuboid is separated two 1 The cuboid of * 1 meter * 0.5 meter of rice, respectively as native liquid collecting region(2)With swash plate Disengagement zone(4);4th, in native liquid collecting region (2)With swash plate Disengagement zone(4)Lower section builds deep 0.5 meter, the bucket that 60 ° of inclination angle respectively(3), the top of bucket is received with native liquid respectively Ji Qu(2)With swash plate Disengagement zone(4)Bottom slitless connection;5th, in native liquid collecting region(2), bucket(3)With swash plate Disengagement zone (4)Inwall on do preservative treatment;6th, in swash plate Disengagement zone(4)The swash plate of internal 60 ° of mounted angle.
