Abstract
Description
Technical Field
[0001] This utility model belongs to the field of environmental remediation and contaminated soil regeneration technology, and specifically relates to a rinsing device. Background Technology
[0002] Soil leaching is a remediation method that uses water or chemical reagents to dissolve or flush out harmful substances from the soil. It works by using water flow to migrate harmful substances from the soil into the water, thereby purifying the soil.
[0003] The commonly used method involves injecting contaminated soil and leachate together into a rotating horizontal mixing tank for mixing, resulting in a mixed slurry. The leachate reacts fully with the contaminants, transferring the contaminants attached to the soil particles to the liquid phase. The mixed slurry is then discharged and allowed to settle for solid-liquid separation. The solid particles and liquid leachate are then treated separately. This method involves two stages: rinsing and mixing, and solid-liquid separation. This process is relatively cumbersome and requires multiple machines. Furthermore, the horizontal mixing tank method has the following problems: soil tends to adhere to the inner wall of the tank. When the soil buildup is thick, the deeper layers cannot easily contact the leachate, resulting in incomplete rinsing and affecting the treatment effect. Additionally, the adhered soil increases the rotational load, requiring periodic shutdowns for cleaning the inner wall of the horizontal mixing tank, which reduces rinsing efficiency. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a rinsing device that has two functions: rinsing and mixing as well as solid-liquid separation. This reduces the number of equipment required for the soil rinsing process, and at the same time, the soil is less likely to stick to the inner wall, reducing the frequency of downtime during the rinsing process. It has the advantages of simple operation, good rinsing effect, and high rinsing efficiency.
[0005] The rinsing device provided by this utility model includes: a drive mechanism, a housing, a rotating drum, a feed pipe, a discharge pipe, a liquid inlet pipe, a plurality of rinsing nozzles and a liquid outlet;
[0006] The drive mechanism drives the rotating drum to rotate around the X-axis inside the housing;
[0007] The inside of the rotating drum has a cavity, and the body of the rotating drum is provided with several through holes;
[0008] The feed pipe passes through the housing and communicates with the cavity from the first end of the rotating drum; the discharge pipe passes through the housing and communicates with the cavity from the second end of the rotating drum; the first end is higher than the second end.
[0009] The liquid inlet pipe is connected to the rinsing nozzle, and the rinsing nozzle passes through the housing and is suspended outside the rotating drum;
[0010] The liquid outlet is located at the bottom of the box.
[0011] The soil to be washed enters the cavity inside the rotating drum through the feed pipe at the first end. Driven by the drive structure, the drum rotates around the X-axis inside the box. The washing liquid flows from the inlet pipe to the washing nozzle and is sprayed out. It enters the cavity inside the rotating drum through the through holes arranged in the drum wall and mixes with the soil. Solid particles remain in the rotating drum, and the washing liquid flows out from the through holes and collects at the outlet at the bottom of the box. As the rotating drum rotates, the solid particles gradually move from the slightly higher first end to the lower second end of the drum and are then discharged from the discharge pipe at the second end. This achieves both the functions of soil washing and mixing and solid-liquid separation of the mixture.
[0012] Furthermore, the second end is an annular baffle, the outer ring of which is connected to the cylinder body of the rotating drum, and the inner ring opening of which is connected to the outlet pipe opening.
[0013] Furthermore, the inner ring opening of the annular baffle protrudes outward along the X-axis. Preferably, the angle between the annular baffle and the X-axis is 30°-45°; the ring width of the annular baffle is 10-15cm.
[0014] The annular baffle at the second end allows for thorough solid-liquid separation of the mixed soil and leachate, preventing solid particles from carrying excessive amounts of leachate out.
[0015] Furthermore, the through holes are evenly distributed in the rotating drum body to achieve uniform rinsing.
[0016] Furthermore, the distance between the rinsing nozzle and the rotating drum is 2-5 cm. Controlling the distance between the rinsing nozzle and the rotating drum ensures that the sprayed rinsing liquid covers a large number of through holes and maintains a certain rinsing intensity to rinse the through holes.
[0017] Furthermore, the rinsing nozzles are evenly distributed in the upper half of the tank so that the rinsing liquid spray range covers the upper half of the rotating drum, achieving a thorough liquid-solid mixing effect under the combined action of gravity.
[0018] Furthermore, the rotating drum also includes a central shaft and several support plates;
[0019] The rotating drum rotates about the axis of the central shaft;
[0020] Several support plates are arranged along the axial direction of the central axis, with one end of each support plate connected to the outer periphery of the central axis and the other end connected to the inner wall of the rotating cylinder.
[0021] The support plate is a spiral blade, and the spiral blade is configured to push the material from the first end to the second end as the drum rotates.
[0022] The spiral blade-shaped support plate inside the rotating drum further enhances the mixing and stirring of soil and leachate within the drum. The mixed liquid and soil are pushed from the first end to the second end to complete liquid-solid separation, and then discharged from the liquid outlet and discharge pipe respectively. The entire leaching process is continuous and smooth, with good leaching effect and high leaching efficiency.
[0023] Furthermore, the first end is a conical baffle, the bottom end of which is connected to the cylinder of the rotating drum, the top end of which is connected to the central shaft, and an annular groove is formed on the conical surface of the conical baffle, which matches and corresponds to the feed pipe.
[0024] A conical baffle at the first end prevents the leached soil that enters the drum from the feed pipe from overflowing the drum.
[0025] Furthermore, the drive mechanism includes a drive motor, a drive gear, and a driven gear;
[0026] The drive gear is fixedly connected to the drive end of the drive motor, and the drive gear meshes with the driven gear. The driven gear is fixedly sleeved on the outer wall of the end of the rotating drum.
[0027] The drive structure can be driven by a drive motor driving a drive gear to drive a driven gear fixedly sleeved on the outer wall of the end of the drum, thereby driving the drum to rotate.
[0028] Furthermore, the drive end of the drive mechanism is connected to the central shaft.
[0029] The drive mechanism can also be directly connected to the central shaft of the drum for driving.
[0030] This utility model has the following beneficial effects:
[0031] 1) The rinsing device provided by this utility model can continuously feed materials and has two functions: rinsing, stirring and mixing, and solid-liquid separation. It automatically and continuously discharges the solid particles and washing liquid after rinsing. It is simple to operate and reduces the number of equipment required for the soil rinsing process.
[0032] 2) The double-layer design of the rotating drum and the box body, with the rinsing ports on the outside of the rotating drum rinsing the drum wall, makes it difficult for soil to stick to the inner wall. The frequency of machine stoppage during the rinsing process is low, and it has the advantages of good rinsing effect and high rinsing efficiency.
[0033] 3) The rotating drum is equipped with a spiral blade plate-shaped support plate to achieve multiple mixing and stirring of the washing liquid and soil, and push the mixed liquid and soil from the first end to the second end. During this movement, liquid-solid separation is completed. The washing liquid and solid particles are discharged from the liquid outlet and the discharge pipe, respectively. The whole washing process is thorough and smooth. Attached Figure Description

[0051] like Figure 1 and Figure 2 As shown, this utility model provides a rinsing device, including a drive mechanism 1, a housing 2, a rotating drum 3, a feed pipe 4, a discharge pipe 5, a liquid inlet pipe 6, several rinsing nozzles 7, and a liquid outlet 8; wherein, the drive mechanism 1 drives the rotating drum 3 to rotate around the X-axis inside the housing 2; the rotating drum 3 has a cavity inside, such as... Figure 3 As shown, the cylinder body of the rotating drum 3 has several through holes; the feed pipe 4 passes through the box body 2 and connects to the cavity from the first end 31 of the rotating drum 3; the discharge pipe 5 passes through the box body 2 and connects to the cavity from the second end 32 of the rotating drum 3; the first end 31 is higher than the second end 32; the liquid inlet pipe 6 connects to the rinsing nozzle 7, and the rinsing nozzle 7 passes through the box body 2 and is suspended on the outside of the rotating drum 3; the liquid outlet 8 is located at the bottom of the box body 2.
[0052] The working process of the rinsing device in this embodiment is as follows: The drive mechanism 1 is started, and the drive mechanism 1 drives the rotating drum 3 to rotate around the X-axis inside the box 2; the liquid inlet pipe 6 delivers the prepared rinsing liquid or water to the rinsing nozzle 7, which sprays the water onto the rotating drum 3 through the rinsing nozzle 7 and enters the cavity inside the rotating drum 3 through the through hole on the rotating drum 3; the soil to be rinsed enters the cavity inside the rotating drum 3 through the feed pipe 4 set at the first end 21, mixes with the rinsing liquid and rotates, the solid particles remain in the rotating drum 3, and the rinsing liquid flows out from the through hole and collects to the liquid outlet 8 at the bottom of the box 2 and flows out. As the rotating drum 3 rotates, the solid particles gradually move from the slightly higher first end 21 of the rotating drum 3 to the lower second end 22, and then are discharged from the discharge pipe 5 set at the second end 22. This realizes the two functions of soil rinsing and mixing and solid-liquid separation of the mixture, and the rinsing work can be carried out continuously.
[0053] Preferably, such as Figure 3 As shown, through holes are evenly distributed throughout the rotating drum 3 to achieve uniform rinsing. Preferably, the distance between the rinsing nozzles 7 and the rotating drum 3 is 2-5 cm; the rinsing nozzles 7 are evenly distributed in the upper half of the housing 2. The distance between the rinsing nozzles 7 and the rotating drum 3 is controlled to ensure that the sprayed rinsing liquid covers a large number of through holes and maintains a certain rinsing intensity to rinse the through holes. Preferably, the rinsing nozzles 7 are evenly distributed in the upper half of the housing 2 so that the spraying range of the rinsing liquid covers the upper half of the rotating drum 3, and the rinsing liquid and soil achieve a thorough liquid-solid mixing effect under the action of gravity during the rotation of the rotating drum 3.
[0054] like Figure 1 As shown, in one embodiment of this invention, the second end 32 is an annular baffle. The outer ring of the annular baffle is connected to the cylinder body of the rotating drum 3, and the inner ring opening of the annular baffle is correspondingly connected to the outlet pipe 5. In this embodiment, the inner ring opening of the annular baffle can bulge outward along the X-axis. Preferably, the angle between the annular baffle and the X-axis is 30°-45°; the ring width of the annular baffle is 10-15cm. The annular baffle at the second end 32 allows for thorough solid-liquid separation of the mixed soil and leachate, preventing solid particles from carrying excessive leachate from being discharged from the outlet pipe 5.
[0055] like Figure 1 and Figure 4 As shown, in one embodiment of this utility model, the rotating drum 3 further includes a central shaft 33 and several support plates 34; wherein, the rotating drum 3 rotates around the axis of the central shaft 33; the several support plates 34 are arranged along the axial direction of the central shaft 33, one end of the support plate 34 is connected to the outer periphery of the central shaft 33, and the other end is connected to the inner wall of the rotating drum 3; the support plate 34 is a spiral blade, and the rotation direction of the spiral blade is configured to push the material from the first end 31 to the second end 32 as the rotating drum 3 rotates. In this embodiment, the spiral blade-shaped support plate provided inside the rotating drum 3 further enhances the mixing and stirring of soil and leachate in the rotating drum 3, and pushes the mixed liquid and soil from the first end 31 to the second end 32 to complete the liquid-solid separation and discharge from the liquid outlet 8 and the discharge pipe 5 respectively. The entire leaching process is continuous and smooth, with good leaching effect and high leaching efficiency.
[0056] like Figure 1As shown, in a preferred embodiment of the above implementation, the first end 31 is a conical baffle. The bottom end of the conical baffle is connected to the cylinder body of the rotating drum 3. An annular groove is formed on the conical surface of the conical baffle, and the annular groove matches and corresponds to the feed pipe 4. Specifically, the conical baffle is welded to the edge of the first end 31 of the rotating drum 3, and the conical baffle is inclined at 60° towards the central axis of the rotating drum 3; the length of the annular conical surface of the conical baffle near the edge of the rotating drum body is not less than 15cm, and the edge of the annular groove is 0.5-1cm away from the feed pipe 4. In this preferred embodiment, the conical baffle provided at the first end 31 prevents the washed soil entering the rotating drum 3 from the feed pipe 4 from overflowing the rotating drum 3.
[0057] The rinsing device provided by this utility model has two different combinations of drive mechanisms. One type includes a drive mechanism 1 comprising a drive motor, a drive gear, and a driven gear. The drive gear is fixedly connected to the drive end of the drive motor, meshing with the driven gear, which is fixedly sleeved on the outer wall of the end of the rotating drum 3. This combination is adaptable regardless of the presence or absence of a central shaft 33. The drive motor drives the drive gear to drive the driven gear fixedly sleeved on the outer wall of the end of the rotating drum 3, thereby causing the rotating drum 3 to rotate. In this combination, the first end 31 can also be equipped with an annular baffle similarly configured to the second end 32 to prevent soil entering the rotating drum 3 from the feed pipe 4 from overflowing. Figure 1 and Figure 1 As shown, the second type is a rinsing device equipped with a central shaft 33, where the driving end of the driving mechanism 1 is directly connected to the central shaft of the rotating drum 3 for driving, thereby causing the rotating drum 3 to rotate.
[0058] The above provides a detailed description of the rinsing device provided by this utility model. The technical features of the embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
