Problems solved by technology

Acidic wastewater carries a large amount of heavy metal ions into the groundwater or pollutes the soil and water around the mining area, affecting crop growth and causing serious environmental problems
[0004] At present, the method adopted in the comprehensive management of mine wasteland is relatively simple, that is, to realize the function of ecological restoration through simple topsoil covering and vegetation planting
However, covering soil is not only difficult to neutralize the acidity in the matrix and prevent pyrite oxidation and re-acidification, but will worsen the degree of re-acidification of the soil

Embodiment 1

[0023] see Figure 1~3 , in an embodiment of the present invention, an ecological restoration device for a pyrite mine abandoned land, comprising a car body 1 and a feeding pipe vertically installed on the car body 1; a lifting pipe 18 is slidingly installed inside the feeding pipe, The lower side of the pipe 18 is inclined to be provided with a material guide channel 23, and two feed ports 22 are symmetrically provided on the left and right side walls of the feeding pipe. Storage tank 26, the first storage tank 15 and the second storage tank 26 communicate with the two feed ports 22 through the feeding pipe 16 respectively, and the lifting pipe 18 slides up and down inside the feeding pipe, when the material guide channel After 23 is aligned and communicated with the feed port 22 on one side, the material in the storage tank on the corresponding side flows into the inside of the material guide channel 23 along the lower material tube 16, and slides up and down on the lifting ...

Embodiment 2

[0032] see Figure 4 , the difference between this embodiment and embodiment 1 is;

[0033] A top plate 30 is installed above the feed pipe, and a cam 31 is installed on the lower side of the top plate 30. The cam 31 is located directly above the pressing plate 17. When the cam 31 rotates, it squeezes the pressing plate 17 intermittently, driving the lifting pipe 18 to descend; Said lifting pipe 18 is provided with a slide block 31 on the outside of the pipe section inside the feed pipe, and the inside of the feed pipe is provided with a chute that cooperates with the slide block 31. The slide block is slidably installed inside the chute, and the upper and lower sides of the slide block are respectively The two telescopic springs 33 are fixedly connected to the chute, so that under the cooperation of the cam 31, the elevating tube 18 can continuously move up and down to complete continuous feeding.

Abstract

The invention discloses a pyrite mining wasteland ecological restoration device. The ecological restoration device comprises a vehicle body and a feeding pipe vertically installed on the vehicle body.A lifting pipe is mounted in the feeding pipe in a sliding manner; a material guide channel is obliquely formed in the lower side of the lifting pipe, two feeding openings are symmetrically formed inthe left side wall and the right side wall of the feeding pipe, a first material storage barrel and a second material storage barrel are further symmetrically arranged on the left side and the rightside of the feeding pipe, and the first material storage barrel and the second material storage barrel communicate with the two feeding openings through discharging pipes correspondingly; a first threaded rod is rotationally installed on the lower side of the vehicle body, a first threaded sleeve is in threaded connection with the first threaded rod, the upper side of the first threaded sleeve isslidably connected with the vehicle body, a spreading head is fixedly installed on the lower side of the first threaded sleeve, and a discharging head is fixedly installed at the lower end of the feeding pipe, is of a hollow structure and communicates with the spreading head through a guide pipe. The migration and transformation of a pollution source are controlled from the source, and secondary acidification and pollution of soil are eradicated.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to an ecological restoration device for pyrite mine abandoned land. Background technique [0002] Mineral resources are an important material basis for the survival and development of human beings, and have made great contributions to the development of human society and the rapid progress of civilization. But at the same time, the development and utilization of mineral resources has also produced a large number of abandoned mines. Mine mining and smelting have formed 4 billion tons of tailings, and it is still increasing at a rate of 2 million tons per year. Abandoned mine land not only occupies a large amount of land resources, but also causes damage to the ecological environment, and even threatens the safety of human life. It urgently needs to be properly treated and repaired. [0003] The matrix of mine waste land has the characteristics of poor physical structure, l...
