Description

Technical Field

[0001] This utility model belongs to the field of soil remediation technology, specifically a soil remediation device that is easy to clean. Background Technology

[0002] Soil remediation refers to the process of reducing the concentration or bioavailability of pollutants (such as heavy metals, organic matter, pathogens, etc.) in soil through physical, chemical, and biological technologies, thereby restoring the soil's ecological function and usability. Physical methods of soil remediation include soil replacement / replacement, deep tillage, electroremediation, and thermal desorption. Electroremediation works by inserting electrodes into contaminated soil and applying a direct current electric field. The electric field drives heavy metal ions or charged organic matter to migrate towards the electrodes, where they are collected and removed. However, it still has the following drawbacks:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Depend on Figure 1-7 The present invention relates to a soil remediation device that is easy to clean, including a soil remediation electrode 1. The soil remediation electrode 1 includes an electrode body 101, one end of which is connected to a power transmission wire, and an external cleaning component 2 is sleeved and installed on the outside of the electrode body 101.

[0029] The external cleaning component 2 includes a cleaning element 205 installed on the outside of the electrode body 101. The cleaning element 205 includes a scraper ring 2051 sleeved on the outside of the electrode body 101. The inner wall of the scraper ring 2051 is in close contact with the outer wall of the electrode body 101, and the scraper ring 2051 is made of insulating material. A nozzle 2052 is installed at the bottom end of the scraper ring 2051 at equal angles. The nozzle of the nozzle 2052 is inclined towards the side of the electrode body 101. An air inlet 204 is installed on the outside of the scraper ring 2051. A side ring 2053 is fixedly installed on the outside of the scraper ring 2051. An air inlet hole 2054 is opened at equal angles on the side ring 2053. The air inlet hole 2054 penetrates into the interior of the scraper ring 2051. A toothed ring 2055 is fixedly installed on the outside of the side ring 2053.

[0030] The air intake component 204 includes an outer sleeve 2041 fitted around the side ring 2053. The outer sleeve 2041 is rotatably connected to the side ring 2053, and the inner top wall and inner bottom wall of the outer sleeve 2041 are respectively tightly fitted to the top wall and bottom wall of the side ring 2053. An air intake pipe 2042 is installed on one side of the outer sleeve 2041. One end of the air intake pipe 2042 is connected to an air pump through a hose. A side box 2043 is installed on the side of the outer sleeve 2041 away from the air intake pipe 2042. The inner cavity of the side box 2043 is connected to the inner cavity of the outer sleeve 2041. A rotating groove 2044 is opened at the top of the side box 2043, and a rotating component 203 is connected and installed on the side box 2043.

[0031] The rotating component 203 includes a screw 2031, the bottom end of which is rotatably connected to an outer sleeve 2041. The outer sleeve 2041 is fitted onto the outside of the scraper ring 2051, so that after the screw 2031 rotates, it can push the scraper ring 2051 downward. On the one hand, the scraper ring 2051 can scrape mud off the electrode body 101; on the other hand, air is blown from the nozzle 2052 toward the outer wall of the electrode body 101 for cleaning, facilitating the cleaning of the soil remediation equipment. A limiting rotating block 2033 is installed at the bottom end of the screw 2031. The limiting rotating block 2033 is rotatably connected to the rotating groove 2044. A gear 2034 is installed at the bottom end of the limiting rotating block 2033. 034 is located inside the side box 2043, and gear 2034 meshes with air inlet 2054. A handle 2032 is installed at the top of screw 2031. The external cleaning component 2 also includes a horizontally arranged fixing plate 201. A screw barrel 202 is installed on the fixing plate 201. Screw 2031 is threadedly connected to screw barrel 202. Gear 2034 is installed at the bottom of screw 2031. A toothed ring 2055 is installed on the outside of side ring 2053. Gear 2034 meshes with toothed ring 2055, so that screw 2031 rotates and pushes scraper ring 2051 to move downward, while scraper ring 2051 rotates continuously, increasing the cleaning range of nozzle 2052 and improving the cleaning effect.

[0032] The bottom end of the electrode body 101 is provided with a sharp part 103, and the top end of the electrode body 101 is provided with a top shell 102. The fixing plate 201 is fixedly installed on the side wall of the top shell 102.

[0033] Working principle: When soil remediation is required, the electrode body 101 is inserted into the soil. Since the bottom end of the electrode body 101 is provided with a sharp part 103, it is easy to insert the electrode body 101 into the soil. After being energized, a DC electric field is applied, and the electric field force drives heavy metal ions or charged organic matter to migrate to the electrode, and they are collected and removed through the electrode area.

[0034] After the soil remediation is completed, the electrode body 101 is pulled out, and then an air pump is connected to the air inlet pipe 2042 through a hose. Then, the worker holds the top shell 102 with one hand and the handle 2032 with the other hand. Rotating the handle 2032 drives the screw 2031 to rotate. Since the limiting block 2033 is rotatably connected to the rotating groove 2044, and the outer sleeve 2041 is fitted on the outside of the mud scraper ring 2051, and the screw 2031 is threadedly connected to the screw barrel 202, the mud scraper ring 2051 moves downward along the electrode body 101 when rotating. On the one hand, it scrapes off the soil attached to the surface of the electrode body 101. On the other hand, driven by the air pump, air enters the mud scraper ring 2051 and is sprayed out from the nozzle 2052 to the surface of the electrode body 101 to blow away the soil on the surface of the electrode body 101, which is convenient for cleaning.

[0035] Meanwhile, since a toothed ring 2055 is installed on the outer side of the side ring 2053, and a gear 2034 is installed at the bottom of the limiting rotating block 2033, the toothed ring 2055 and the gear 2034 mesh with each other, so that when the screw 2031 rotates, it drives the scraper ring 2051 to move along the electrode body 101 and rotates at the same time, increasing the blowing range of the nozzle 2052 on the surface of the electrode body 101 and improving the cleaning effect.
