Description

Technical Field

[0001] The utility model belongs to the technical field of soil remediation machinery, and particularly relates to an automatic mud scraping device for a feeding belt of a soil remediation stirring device. Background Art

[0002] At present, in the field of soil remediation, ex-situ dosing treatment is adopted for contaminated soil. Mainly, a forced stirring device is used to mix the contaminated soil and the remediation agent evenly to achieve the treatment effect. The main way to feed the contaminated soil and the remediation agent into the stirring device is through a belt feeding system. The belt feeding system mainly includes a front receiving hopper, a belt conveyor, a power system, etc. The operation mode is that the contaminated soil after pre-treatment in the front section is fed into the receiving hopper mechanically, and at the same time, the remediation agent is added into the receiving hopper. After premixing, it falls onto the belt, and then is conveyed by the belt to the stirring device for stirring, realizing the full mixing of the contaminated soil and the agent.

[0003] Due to the different moisture contents of the contaminated soil entering the receiving hopper and the different forms of the agent, after the belt conveyor conveys the contaminated soil and the agent to the stirring system, mud sticking will occur on the belt. As the operation time increases, the mud sticking on the belt will accumulate continuously, resulting in an increase in the power load of the belt conveyor and affecting the normal operation of the belt feeding system. At present, the main measure taken for the problem of mud sticking on the belt is to manually clean the mud sticking on the belt in an area convenient for operation. However, this treatment has low efficiency. At the same time, during the operation of the belt, some mud may fall to the ground, causing secondary pollution and possibly harming the operators below.

[0004] Therefore, there is an urgent need for an automatic mud scraping device for a feeding belt of a soil remediation stirring device to well solve the problems that the mud sticking on the belt of the belt feeder increases the power load of the belt conveyor, affects the normal operation of the belt feeding system, and the manual cleaning of the mud sticking on the belt has low efficiency, and some mud falls to the ground, causing secondary pollution and possibly harming the operators below.
