Breaking and refining device for environment-protecting remediation of soil

Abstract

The invention discloses a breaking and refining device for environment-protecting remediation of soil, and belongs to the technical field of soil remediation. The breaking and refining device for environment-protecting remediation of the soil comprises a base, wherein the output end of a motor penetrates through the top face of a baffle, extends to the lower portion and is coaxially and fixedly connected with a middle shaft; a plurality of rotating rods are evenly arranged on the outer wall of the middle shaft in an inserted mode at equal intervals, limiting grooves are formed in the positions, corresponding to limiting rings, in an interlayer of the outer wall of the middle shaft, and a plurality of stirring rods are annularly and fixedly arranged at the outer side end of the rotating rods at equal intervals; and a fixing shaft is coaxially arranged in the middle portion of a shaft groove, a plurality of circular discs are linearly arranged outside the fixing shaft in a sleeving mode at equal intervals, a plurality of tooth grooves are annularly formed in the outer walls of the circumferences of the circular discs at equal intervals, and bevel gears are coaxially and fixedly connected to the positions, corresponding to the tooth grooves, of the inner side ends of the rotating rods. According to the breaking and refining device for environment-protecting remediation of the soil, the breaking fineness of the soil can be greatly enhanced, so that dead angles do not exist in the breaking and refining process of the soil inside a refining cylinder, soil refining and breaking work is faster, and more time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, and more specifically, relates to a crushing and refinement device for soil environmental protection remediation. Background technique [0002] Soil remediation is a technical measure to restore contaminated soil to normal functions. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three types: physical, chemical and biological. method, in the process of soil remediation, the soil needs to be crushed and refined, so that the soil can fully contact with the treatment agent in the future. [0003] After searching, the patent with the publication number CN111760894A discloses a crushing and refining device for soil environmental protection restoration. The translation mechanism can be driven by the forward and reverse drive mechanism, and the dri...

Problems solved by technology

[0004] The existing device can effectively refine the soil, but the driving shaft and the crushing blade in it rely on the drive of the threaded rod 1 to realize the work of refining all the soil in the crushing cylinder. The drive shaft and the crushing blade will push the soil to the outside during the translation process, which will cause the crushing efficiency of the device to be greatly reduced. Moreover, when the device refines the soil, there will be some problems due to the viscosity of the soil. Adhering to the inner wall of the crushing cylinder, these soils will be very difficult to clean up after drying, which will cause a great cleaning burden for the staff. In addition, in the existing devices (such as CN212780182U, CN212418175U), they all use stirring and crushing before passing through The soil is refined by crushing or grinding, but because the soil is transferred inside the device, there will be problems such as blockage and stickiness during the transfer process, which will affect the efficiency of crushing and discharging. In view of this, we propose a method for soil environmental protection restoration Crushing and refining device
