Description

Technical Field

[0001] The utility model relates to the technical field of soil cleaning, in particular to a soil cleaning device with a wastewater recovery mechanism. Background Art

[0002] Soil environmental pollution, referred to as soil pollution, refers to the phenomenon that pollutants generated by human activities enter the soil and accumulate to a certain extent, causing the deterioration of soil quality. With the development of modern industrial and agricultural production, the large-scale use of fertilizers and pesticides, the discharge of industrial wastewater into farmland, and the continuous discharge of urban sewage and waste into the soil, the quantity and speed of these environmental pollutants exceed the soil's bearing capacity and purification speed, thereby destroying the natural dynamic balance of the soil, causing the soil quality to decline and causing soil pollution. Therefore, more and more polluted soils now need to use soil washing equipment to thoroughly clean the polluted soil, so as to achieve the purpose of soil purification.

[0003] When performing soil restoration and leaching, one of the steps is to clean the soil through a soil cleaning device. The corresponding chemical agents are sprayed to combine with the pollutants in the soil. Through the chemical effects of desorption, dissolution or fixation of these chemical liquids, the purpose of repairing the contaminated soil is achieved. Some of the cleaning devices spray the soil conveyed on a conveyor belt. However, due to the long-term spraying of liquid chemicals, the soil after spraying carries a large amount of liquid. These water stains will flow out and produce a large amount of wastewater. Most of these wastewaters drip from the device onto the ground, leaving a large amount of water stains on the ground, resulting in serious waterlogging on the ground. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-5 A soil cleaning device with a wastewater recovery mechanism comprises a cleaning box 1, a conveyor belt 4 is arranged in the cleaning box 1, and one end of the conveyor belt 4 extends from the cleaning box 1 to the outside of the cleaning box 1, a mud guide plate 5 is arranged outside the cleaning box 1 and below the conveying end of the conveyor belt 4, a mud scraping mechanism 6 is arranged on the upper surface of the mud guide plate 5, a wastewater recovery box 7 is arranged below the mud guide plate 5, and a guide plate 8 is arranged below the cleaning box 1.

[0021] In addition, a discharge port 2 is provided on the cleaning box 1, and a plurality of spray pipes 3 are evenly arranged on one side of the discharge port 2, and the bottom of the discharge port 2 is aligned with the conveyor belt 4. The lower surface of the cleaning box 1 is open, and the opening at the bottom of the cleaning box 1 facilitates that most of the sewage generated by the soil after spraying and dripping on the conveyor belt 4 can drip into the guide plate 8 below.

[0022] In addition, a drainage plate 51 is provided on the mud guide plate 5, and the mud guide plate 5 is inclined at a certain angle, so that the mud guide plate 5 guides the soil to the conveyor belt below and transports it to the subsequent processing equipment.

[0023] In addition, the mud scraping mechanism 6 includes a rotating motor 61, which is symmetrically installed on one side of the mud guide plate 5, and a rotating shaft 62 is installed at the output end of the rotating motor 61 on both sides. The rotating shaft 62 rotates with the output end of the rotating motor 61 as the axis, and a plurality of scrapers 63 are evenly installed on the shaft body of the rotating shaft 62 located above the drainage plate 51. There is a little distance between the bottom end of the scraper 63 and the upper surface of the drainage plate 51. The scraper 63 cooperates with the rotating shaft 62 and is driven to rotate by the rotating motor 61, so that the scraper 63 can scrape the soil downward, thereby facilitating the soil to slide down better and preventing the soil from accumulating on the mud guide plate 5.

[0024] In addition, a filter plate 71 is horizontally placed on the wastewater recovery box 7, and placement grooves 73 are symmetrically provided on both sides of the upper surface of the wastewater recovery box 7. The placement grooves 73 are used to place the convex plates on both sides of the filter plate 71. A drain pipe 72 is connected to one side of the inner cavity of the wastewater recovery box 7. The drain pipe 72 facilitates the regular discharge of sewage in the wastewater recovery box 7, and the filter plate 71 facilitates filtering impurities in the dripping sewage to prevent blockage in the drain pipe 72 due to accumulation over time.

[0025] In addition, the guide plate 8 is arranged at a certain inclined angle below the cleaning box 1, and the end of the guide plate 8 at a lower height is located above the wastewater recovery tank 7, and a guide cavity 81 is opened in the guide plate 8, which facilitates diverting the sewage dripping from the cleaning box 1 to the wastewater recovery tank 7.

[0026] In this embodiment, when the treated soil is sent to the cleaning box 1 for spray cleaning, the soil is first discharged from the previous process to the discharge port 2, and then falls from the discharge port 2 onto the conveyor belt 4. The conveyor belt 4 will convey the soil to the guide plate 5. During this process, the multiple spray pipes 3 arranged on the cleaning box 1 will continuously spray out the eluent or chemical agent to repair the soil. At this time, the soil will become wet after being sprayed with the eluent or chemical agent, thereby generating some waste water. A part of the waste water will drip from the conveyor belt 4 and then drip into the guide plate 8 under the cleaning box 1. With the inclined guide plate 8, the waste water can be diverted from the diversion cavity 81 to the waste water recovery tank 7.

[0027] The soil transmitted from the conveyor belt 4 to the cleaning box 1 will fall on the drain plate 51 of the mud guide plate 5 due to the action of gravity, and the soil will slowly slide downward due to the inclined mud guide plate 5, and the wastewater generated in the wet soil will drip from the drain plate 51 to the bottom. The small pieces of the drain plate 51 can only be passed by liquid, while most of the soil cannot pass through, and the wastewater will drip from the drain plate 51 into the wastewater recovery tank 7 below, and enter the wastewater recovery tank 7 together with the wastewater flowing out of the guide cavity 81, and the filter plate 71 can effectively filter impurities in the dripping wastewater.

[0028] In addition, the staff needs to clean the drain plate 51 regularly to dredge it by cleaning it to prevent it from being blocked by soil after long-term use. The filter plate 71 can be lifted from the placement groove 73 by cooperating with the convex plates on both sides of the filter plate 71, thereby cleaning the filter plate 71 and the wastewater recovery box 7 to ensure the service life of the equipment.

[0029] When the soil is on the mud guide plate 5, the mud scraping mechanism 6 is also running, and the rotating motors 61 on both sides rotate counterclockwise, so that while the rotating shaft 62 rotates, the scraper 63 continues to rotate to scrape the soil continuously, thereby driving the soil to slide down to the subsequent conveyor belt to prevent the soil from accumulating on the drainage plate 5.

[0030] In the utility model, a guide plate 8 is arranged at the bottom of the cleaning box of the cleaning device for spraying and repairing the soil, so that the guide plate 8 can effectively collect the waste water dripping from the cleaning box 1 and guide it to the waste water recovery box 7 for collection. When the soil is transported out from the conveyor belt 4 and falls, an intermediate transition mud guide plate 5 is arranged, so that the waste water in the soil can drip from the mud guide plate 5 and enter the waste water recovery box 7 below, so as to achieve effective recovery of the waste water generated after the soil is sprayed, prevent the waste water from directly dripping from the device to the ground to generate water accumulation, and ensure that the waste water will not be wasted and can be recovered.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
