Description

Technical Field

[0001] This utility model relates to the field of soil pollution remediation technology, specifically to a cleaning device for remediating soil pollution. Background Technology

[0002] Polluted soil is soil containing one or more substances that are harmful to biological or human health, or the content of these substances exceeds the soil's self-purification capacity, causing changes in the soil's chemical, physical, or biological properties, thereby affecting the soil's function. When treating soil pollution, the collected soil is first poured into a corresponding screening drum. As the drum rotates, stones and solid impurities inside the soil are screened to prevent impurities from accumulating arbitrarily and affecting the quality of subsequent treatment agents in removing soil pollutants.

[0003] In practical use, when the collected soil is poured into the corresponding screening drum for rotary screening, the outer side of the drum is made of metal mesh. This not only prevents some soil clumps from breaking up during rotation, allowing solid impurities such as stones to remain trapped inside, but also easily causes impurities of a size that matches the inner diameter of the mesh to become clogged in the drum's mesh during screening. To prevent the normally screened soil from failing to pass through the mesh drum, operators need to clean the inner mesh of the drum regularly. This is time-consuming and labor-intensive, and if cleaning is not timely, the soil screening and discharge rate may be insufficient, thus reducing the efficiency of subsequent soil pollution remediation. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, adapt to practical needs, and provide a cleaning device for soil pollution remediation. This device addresses the problem that when collected soil is poured into a screening drum for rotary screening, the outer side of the drum is a metal mesh. This not only prevents some soil clumps from breaking during rotation, causing solid impurities like stones to remain trapped inside, but also easily leads to impurities of a size matching the mesh diameter clogging the drum's mesh during screening. To prevent the normally screened soil from failing to pass through the mesh drum, operators must periodically clean the internal mesh, which is time-consuming and labor-intensive. Furthermore, untimely cleaning can easily result in insufficient soil screening and discharge rates, thus reducing the efficiency of subsequent soil pollution remediation.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a cleaning device for treating soil pollution, including a mounting base, a screening roller rotatably mounted on the top of the mounting base, and a guide frame fixedly mounted on the top side of the mounting base;

[0006] A transmission frame is vertically fixed in the middle of the top side of the mounting base away from the guide frame. A synchronization mechanism is provided inside the transmission frame. A tapping mechanism is provided on the top side of the transmission frame. An agitation mechanism is provided on the bottom side of the transmission frame. The tapping mechanism and the agitation mechanism are connected by the synchronization mechanism.

[0007] Preferably, the tapping mechanism includes a tapping belt, a transmission sleeve is rotatably mounted on the top side of the transmission frame via a bearing, a rotating shaft is slidably inserted inside the transmission sleeve, a connecting sleeve is fixedly sleeved on the outside of the rotating shaft, and a tapping belt is fixedly mounted on the outside of each connecting sleeve.

[0008] Preferably, the agitation mechanism includes a crushing cone plate, a rotating rod is rotatably mounted on the bottom side of the transmission frame, a fixed sleeve is fixedly sleeved on the outside of the rotating rod, and there are several sets of fixed sleeves. A connecting plate is fixedly mounted on the outer wall of each fixed sleeve, a transmission plate is fixedly mounted on the side of each connecting plate away from the fixed sleeve, and a crushing cone plate is fixedly mounted on both ends of the outer side of each transmission plate.

[0009] Preferably, the synchronization mechanism includes a transmission sprocket, a follower sprocket, and a transmission chain. A first transmission rod is rotatably mounted on the top inner side of the transmission frame via a bearing, and the top edge of the first transmission rod is fixedly connected to the top edge of the transmission sleeve. A second transmission rod is rotatably mounted on the bottom inner side of the transmission frame via a bearing, and the top edge of the second transmission rod is fixedly connected to the top edge of the rotating rod. A servo motor is fixedly mounted on the outer side of the transmission frame, and the side of the servo motor's transmission shaft is fixedly connected to the top edge of the second transmission rod via a coupling. A transmission sprocket is fixedly sleeved on the middle outer side of the first transmission rod, and a follower sprocket is fixedly sleeved on the middle outer side of the second transmission rod. A transmission chain meshes between the outer sides of the transmission sprocket and the follower sprocket.

[0010] Preferably, both ends of the outer side of the screening drum are rotatably sleeved with support sleeves via bearings. Each support sleeve has a support plate vertically fixedly installed at both ends of its outer bottom. The bottom of the support plate is fixedly connected to the top of the mounting base. Mounting plates are vertically fixedly installed on both sides of the top of the mounting base. A fixing rod is rotatably installed between the sides of the two sets of mounting plates via bearings. A rotating motor is fixedly installed at the top of the side of the mounting plate. The side of the rotating motor's drive shaft is fixedly connected to the top of the side of the fixing rod via a coupling. Transmission gears are fixedly sleeved at both ends of the outer side of the fixing rod. Transmission gear rings are fixedly sleeved at both ends of the outer side of the screening drum.

[0011] Preferably, a first insertion hole is vertically opened in the middle of the transmission sleeve, and a second insertion hole is vertically opened at the top side of the rotating shaft. A fastening bolt is slidably inserted through the first insertion hole and the second insertion hole, and a connecting nut is screwed onto the bottom outer side of the fastening bolt by threads.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model features a transmission frame vertically arranged on the side of a screening drum, with a rotatable first transmission rod and a second transmission rod respectively located at both ends of the transmission frame. A follower sprocket and a transmission sprocket are respectively sleeved on the outer sides of the first and second transmission rods. Combined with a transmission chain, the transmission sprocket and the follower sprocket mesh and transmit power. When the servo motor provides rotational driving force to the first transmission rod, the first and second transmission rods rotate synchronously and in the same direction on both sides inside the transmission frame. This drives the transmission shaft and rotating rod connected to the first and second transmission rods to rotate synchronously and in the same direction on the outer and inner sides of the screening drum, respectively. Consequently, the transmission plate and crushing cone plate located on the outer side of the rotating rod rotate inside the screening drum, allowing the crushing cone plate to rotate... While contact-crushing and breaking up the soil material poured inside the screening drum, the rotating shaft at the top and the beater belt sleeved on its outside rotate synchronously on the outside of the screening drum. The beater belt can repeatedly beat the outer wall of the screening drum as it rotates, causing the outer shell of the screening drum to vibrate under the contact action of the beater belt. This allows the stones and materials blocked in the mesh of the screening drum to automatically detach under the repeated action of vibration. At the same time, the crushing cone plate can contact-break up the soil material clumps inside the screening drum, achieving the screening and cleaning of stone impurities mixed in with the soil. This reduces the labor consumption required for the operator to clean the mesh of the screening drum surface and avoids excessive blockage and accumulation of stone impurities, which would affect the screening and cleaning quality of the soil material.

[0014] 2. This utility model, by providing a first insertion hole and a second insertion hole on the side of the rotating shaft and the transmission sleeve respectively, allows for quick disassembly and separation of the rotating shaft and the transmission sleeve. This is achieved when the beating belt wears down or even breaks due to prolonged rotation and contact with the outer wall of the screening drum. The tightening action of the fastening bolts and connecting nuts allows the fastening bolts to be removed from the rotating shaft and the transmission sleeve, facilitating rapid replacement of the rotating shaft and the beating belt. Simultaneously, the limiting connection of the fastening bolts and connecting nuts ensures that the rotating shaft inside the transmission sleeve rotates as well, guaranteeing sufficient contact vibration force from the beating belt against the outer wall of the screening drum. This further ensures that stones and impurities clogging the inside of the screening drum can be removed, improving the screening and cleaning quality of stones and impurities in the soil.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] Example 1: A cleanup device for treating soil pollution, see [link to example]. Figures 1 to 4 A screening roller 13 is rotatably mounted on the top of the mounting base 1. The screening roller 13 is positioned with the left side higher than the right side on the top of the mounting base 1. A guide frame 14 is fixedly mounted on the side of the top of the mounting base 1, and the right side of the guide frame 14 is attached to the left feed end of the screening roller 13.

[0026] Both ends of the outer side of the screening drum 13 are fitted with support sleeves via bearings. Each support sleeve has a support plate 11 fixedly installed at both ends of its outer bottom. The bottom of the support plate 11 is fixedly connected to the top of the mounting base 1. Mounting plates 4 are fixedly installed vertically on both sides of the top of the mounting base 1. A fixing rod 41 is rotatably installed between the two sets of mounting plates 4 via bearings. A rotating motor 44 is fixedly installed at the top of the side of the mounting plate 4. The side of the drive shaft of the rotating motor 44 is fixedly connected to the top of the side of the fixing rod 41 via a coupling. Both ends of the outer side of the fixing rod 41 are fitted with transmission gears 42. Both ends of the outer side of the screening drum 13 are fitted with transmission gear rings 43. Both the outer side of the transmission gears 42 and the outer side of the transmission gear rings 43 are provided with intermeshing tooth blocks.

[0027] When the servo motor 35 is turned on by an external control switch, causing it to rotate synchronously with the fixed rod 41, the fixed rod 41, through its connecting transmission action, drives the transmission gear 42, which is sleeved on its outer side, to rotate synchronously. Combined with the meshing transmission action of the transmission gear 42 and the transmission gear ring 43, the transmission gear ring 43 can synchronously drive the screening drum 13 to rotate along with the rotation of the transmission gear 42. After the screening drum 13 rotates inside the two sets of transmission sleeves 21, the soil to be screened and cleaned is poured into the guide frame 14. Under the guidance of the screen, the soil raw material can be rolled and moved into the screening drum 13. While the screening drum 13 is rotating, it can roll and screen the soil sample. The screened soil can be removed from the screening drum 13 and fall onto the surface of the mounting base 1. The operator can then shovel and move the screened soil. The stones and impurities screened out from the soil raw material can accumulate inside the inclined screening drum 13. Under its own gravity, they can be discharged from the right side of the screening drum 13, thereby achieving the screening and cleaning of stones and impurities inside the soil raw material.

[0028] For details, see Figures 1 to 4A transmission frame 2 is vertically fixedly installed on the top of the mounting base 1, away from the guide frame 14. A first transmission rod 3 is rotatably installed on the top inner side of the transmission frame 2 via a bearing, and the top side of the first transmission rod 3 is fixedly connected to the top side of the transmission sleeve 21. A second transmission rod 32 is rotatably installed on the bottom inner side of the transmission frame 2 via a bearing, and the top side of the second transmission rod 32 is fixedly connected to the top side of the rotating rod 25. A servo motor 35 is fixedly installed on the outer side of the transmission frame 2, and the side of the transmission shaft of the servo motor 35 is fixedly connected to the top side of the second transmission rod 32 via a coupling. A transmission sprocket 33 is fixedly sleeved on the middle outer side of the first transmission rod 3, and a follower sprocket 31 is fixedly sleeved on the middle outer side of the second transmission rod 32. A transmission chain 34 is meshed between the outer sides of the transmission sprocket 33 and the follower sprocket 31. The transmission sprocket 33, the follower sprocket 31, and the transmission chain 34 are all rotatably disposed inside the transmission frame 2.

[0029] While the soil raw material is being sieved, the servo motor 35 is turned on by an external controller, causing it to rotate and drive the second transmission rod 32 to rotate inside the transmission frame 2. This, in turn, drives the transmission sprocket 33, which is sleeved on the outside of the second transmission rod 32, to rotate at the bottom inside the transmission frame 2. Combined with the meshing transmission action of the transmission chain 34 on the transmission sprocket 33 and the follower sprocket 31, the follower sprocket 31 and the first transmission rod 3 sleeved inside it can rotate synchronously and in the same direction as the second transmission rod 32.

[0030] Further, see Figures 1 to 4 A transmission sleeve 21 is rotatably mounted on the top side of the transmission frame 2 via a bearing. A rotating shaft 22 is slidably inserted inside the transmission sleeve 21. A connecting sleeve 23 is fixedly sleeved on the outside of the rotating shaft 22. There are several sets of connecting sleeves 23. A beater belt 24 is fixedly mounted on the outside of each connecting sleeve 23. There are several sets of beater belts 24. The bottom of the beater belt 24 is movably attached to the outer surface of the screening drum 13.

[0031] A rotating rod 25 is rotatably mounted on the bottom side of the transmission frame 2. A fixed sleeve 26 is fixedly sleeved on the outside of the rotating rod 25. There are several sets of fixed sleeves 26. A connecting plate 27 is fixedly mounted on the outer wall of each fixed sleeve 26. A transmission plate 28 is fixedly mounted on the side of each connecting plate 27 away from the fixed sleeve 26. Crushing cone plates 29 are fixedly mounted on both ends of the outer side of each transmission plate 28. The vertical cross section of the crushing cone plate 29 is triangular.

[0032] Under the driving force of the first transmission rod 3 and the second transmission rod 32, which rotate and transmit power, the connecting sleeve, the rotating shaft 22, and the rotating rod 25 can rotate synchronously and in the same direction on the outer and inner sides of the screening drum 13, respectively. The beater belt 24 sleeved on the outer side of the transmission shaft rotates synchronously on the outer side of the screening drum 13. The side end of the beater belt 24 can repeatedly beat the outer wall of the screening drum 13 as the screening drum 13 rotates, so that the outer shell of the screening drum 13 generates vibration force under the contact action of the beater belt 24. This allows the stone material blocked in the mesh of the screening drum 13 to automatically detach under the repeated action of vibration force. At the same time, the crushing cone plate 29 can contact and break up the soil raw material clumps inside the screening drum 13, so that the stones buried inside the soil raw material clumps can be separated from the soil clumps and easily screened and cleaned.

[0033] It is worth noting that, see Figures 1 to 4 The transmission sleeve 21 has a first insertion hole 5 vertically opened in the middle, and the rotating shaft 22 has a second insertion hole 51 vertically opened at the top side. The first insertion hole 5 and the second insertion hole 51 are slidably inserted into each other. The bottom outer side of the fastening bolt 52 is screwed with a connecting nut 53 by threads, and the connecting nut 53 is located at the bottom outer side of the transmission sleeve 21.

[0034] When the beating belt 24 rotates for a long time, contacting and beating the outer wall of the screening drum 13, causing wear or even breakage of the beating belt 24 itself, resulting in a decrease in the cleaning quality of the internal mesh of the screening drum 13, the connecting nut 53 is loosened to remove it from the outside of the fastening bolt 52. Then, the fastening bolt 52 is pulled to remove it from the first insertion hole 5 and the second insertion hole 51. The rotating shaft 22 is pulled to the left to remove its side end from the transmission sleeve 21. After replacing the rotating shaft 22 and the beating belt 24 on its outer side, the replaced... After the rotating shaft 22 is pushed into the rotating sleeve by the side end, so that the first insertion hole 5 and the second insertion hole 51 are in the same vertical position, the fastening bolt 52 is pushed vertically through the first insertion hole 5 and the second insertion hole 51. Then the connecting nut 53 is turned to limit the fastening bolt 52 to be located inside the first insertion hole 5 and the second insertion hole 51, thus fixing the rotating shaft 22 and the transmission sleeve 21 together. When the transmission sleeve 21 rotates, it can drive the rotating shaft 22 to rotate accordingly, so that the beater belt 24 can beat and clean the surface of the screening drum 13.
