Description

A soil pollution control device with sterilization function

Technical Field

The present invention relates to the technical field of contaminated soil restoration, and in particular to a soil pollution control device with a sterilization function.

Background technique

Soil can be polluted due to human activities (such as agricultural production, industrial activities, improper disposal of urban domestic waste, etc.). Soil pollution will affect the physical, chemical and biological properties of the soil, and thus affect crop growth, human health and the stability of the ecosystem. Therefore, contaminated soil needs to be repaired and managed. In terms of the type of repair, soil repair and management is divided into soil ex situ repair and soil in situ repair. The selection of appropriate repair technology needs to consider the type of soil pollution, the type of pollution source and its distribution in the soil.

For example, when rectifying damaged arable land and dealing with heavy metal and organic pollution, soil ex situ remediation technology is often used. It is necessary to dig out the contaminated soil from the original contaminated land and then backfill it with foreign soil. Since some of the backfilled foreign soil is raw soil with a lot of gravel, it is not possible to grow crops. Therefore, before backfilling, it is necessary to separate the mud and rocks, and then make a slurry for the soil. In the prior art, a drum stone washer is mostly used to separate mud and rocks. However, the existing drum stone washing machine has the following defects when separating mud and rocks: the separation of stones and soil is not thorough, and a certain amount of soil is likely to remain on the surface of the separated small stones, which will cause a loss of soil backfill when the soil is backfilled.

Summary of the invention

Based on this, it is necessary to provide a soil pollution control device with a sterilization function to address the problems existing in the current drum stone washing machine, so as to solve the problem that the separation of stones and soil is not complete, and a certain amount of soil is likely to remain on the surface of the separated small stones.

As shown in Figures 1 to 4, a soil pollution control device with a sterilization function includes a base 100, a first cylinder 200 and a second cylinder 600. The first cylinder 200 is rotatably arranged on the base 100. The first cylinder 200 can rotate around its axis. The first cylinder 200 includes a first left cylinder 210, a first right cylinder 220 and a plurality of stirring bars 230. The cylinder diameter of the first left cylinder 210 is smaller than the cylinder diameter of the first right cylinder 220. The first left cylinder 210 and the first right cylinder 220 are coaxial and The stirring bars 230 are arranged at intervals, and are arranged at equal intervals around the axis of the first left cylinder 210. The two ends of the stirring bars 230 are fixedly connected to the first left cylinder 210 and the first right cylinder 220 respectively. The second cylinder 600 is rotatably arranged on the base 100. The second cylinder 600 can rotate around its axis. The rotation direction of the second cylinder 600 is opposite to that of the first cylinder 200. The second cylinder 600 is coaxial with the first cylinder 200 and surrounds the outside of the area where the stirring bars 230 are located.

It should be supplemented that, in order to facilitate the directional flow of materials in the first cylinder 200 and the second cylinder 600, the base 100 is tilted so that the height of its left side is higher than the height of its right side. Specifically, as shown in Figures 1 and 2, a hydraulic foot pier 120 is provided on the left side of the base 100. The left side of the base 100 is lifted to a certain height by the hydraulic foot pier 120, so that the angle between the lower bottom surface of the base 100 and the horizontal plane is approximately a (a=15°).

It should be additionally explained that a connecting bracket 110 is disposed on the base 100 , a sterilizing liquid filling pipe 500 is disposed on the connecting bracket 110 , and a liquid outlet end of the sterilizing liquid filling pipe 500 is located in the first left tube 210 .

During use, the staff rotates the first barrel 200 and the second barrel 600 around the corresponding axis. At this time, the first barrel 200 and the second barrel 600 rotate and the rotation directions are opposite. Next, the staff adds sterilizing liquid into the first barrel 200 through the sterilizing liquid filling pipe 500. At the same time, the staff adds materials (mud and stone mixture) from the left end of the first barrel 200 into the first left barrel 210. Under the rotation of the first left barrel 210, the materials and the sterilizing liquid are mixed with each other. The sterilizing liquid has two functions. The first function of the sterilizing liquid is to sterilize the soil. The other function of the sterilizing liquid is to soak the mud and stone mixture to reduce the adhesion force between the soil and the stone, so as to facilitate the separation of the soil and the stone. At this time, because the left end of the first left barrel 210 is higher than the right end, the material rolls forward from the first left barrel 210 to the stirring bar 23. 0, after the material reaches the position of the area where the stirring bars 230 are located, the material whose size is smaller than the gap distance of the stirring bars 230 (referred to as small-sized material) falls from the gap between the stirring bars 230 to the area between the second cylinder 600 and the stirring bars 230. Since the rotation direction of the second cylinder 600 is opposite to that of the stirring bars 230, compared with the case where the second cylinder 600 rotates synchronously with the first cylinder 200 or the first cylinder 200 does not rotate, the path length of the small-sized material moving in the second cylinder 600 is longer, the time for the small-sized materials to collide with each other and the time for the small-sized materials to collide with each other and the stirring bars 230 are longer, so the small-sized materials can be fully vibrated, which is beneficial to the separation of soil and stones in the small-sized materials, so that the separation effect of soil and stones in the small-sized materials is better.

It is understandable that the mud-stone mixture (referred to as large-size material) with a size larger than the gap distance between the stirring bars 230 can be quickly moved to the location of the first right cylinder 220 compared to the small-size material of the stirring bars 230, and the large-size material is discharged from the right end of the first right cylinder 220 to avoid too much large-size material staying in the location of the stirring bars 230, causing stress deformation of the stirring bars 230. It should also be noted that the reason why large-size materials do not need to stay in the area where the stirring bars 230 are located for a long time is that the kinetic energy of large-size materials is greater when they collide with each other, and it is easier to shake off the soil adhered to the surface of the stones.

It should also be noted that the longitudinal cross-sectional area of the area surrounded by the stirring bar 230 and the second cylinder 600 gradually decreases from left to right. Therefore, when the feed flow rate is large, it can prevent the material from being unable to fall into the area between the stirring bar 230 and the second cylinder 600 due to accumulation. When the feed flow rate is small, it can also ensure that the material and the stirring bar 230 are in contact with each other, and the stirring bar 230 is used to scrub the material to achieve a good mud and stone separation effect.

In a further embodiment, as shown in FIG. 4 , the stirring bar 230 is twisted along its length direction so that when the material passes through the area where the stirring bar 230 is located, the material is forced to flow from left to right.

By twisting the stirring bar 230 so that the material passes through the area where the stirring bar 230 is located, the material is forced to move from left to right, in order to avoid the problem that the small-sized material cannot move from left to right when there are too few small-sized materials. When there are fewer small-sized materials, the force acting on the small-sized materials is only the component force of its gravity along the inclined surface. If this component force is not enough to overcome the friction between the stirring bar 230 and the small-sized materials, the small-sized materials will not move from left to right. It can be understood that when there are more small-sized materials, the small-sized materials are also pushed by the materials on their left side along the inclined surface, so when there are more small-sized materials, the small-sized materials can move from left to right.

In a further embodiment, as shown in FIG. 4 , the stirring bar 230 is made of elastic metal material.

By making the stirring bars 230 of elastic metal material, it is possible to prevent the material from being stuck in the gaps between the stirring bars 230 and unable to escape, thereby reducing the area for material screening.

It is understandable that materials whose outer dimensions are approximately equal to the gaps between the stirring bars 230 may be stuck in the gaps between the stirring bars 230. If the stirring bars 230 are made of elastic metal, the materials stuck in the stirring bars 230 are more likely to fall out of the gaps between the stirring bars 230 when they collide with other materials, which is equivalent to achieving intelligent unblocking. Therefore, it is possible to prevent the gaps between the stirring bars 230 from being blocked by materials for a long time, thereby reducing the material screening area.

In a further embodiment, as shown in FIG. 2 , inclined plates 211 are arranged at equal intervals on the inner peripheral wall of the first left cylinder 210 .

The inclined plates 211 are arranged at equal intervals on the inner wall of the first left cylinder 210 to have two functions. The first function is to accelerate the rotation of the materials in the first left cylinder 210 to move forward to the area where the stirring bars 230 are located. The second function is to promote the relative movement between the materials in the first left cylinder 210, strengthen the mutual collision effect between the materials, and promote the separation of stones and soil.
