Description

Technical Field

[0001] This utility model relates to the field of groundwater pollution control, and in particular to a debris retrieval device for groundwater pollution control. Background Technology

[0002] In the groundwater pollution remediation process, the removal of solid debris (such as industrial waste particles, dead branches and debris, plastic fragments, etc.) is a critical pretreatment step to ensure the normal operation of subsequent pollution remediation equipment (such as infiltration reaction columns and filtration systems). If such debris is not effectively removed, it can easily cause blockage of pipelines in subsequent equipment and caking of the reaction medium, thereby reducing pollution remediation efficiency and increasing equipment maintenance costs.

[0003] Currently, groundwater debris removal largely relies on mechanical retrieval devices, such as the filtration device for treating rural ditch water pollution proposed in Chinese Patent Publication No. CN210728862U, which uses a rotating roller and a retrieval plate in combination to achieve continuous retrieval operations. However, this device has certain drawbacks: As described in the patent document, the retrieval plate and the rotating roller are designed with a fixed connection (such as welding or integral molding). The posture of the retrieval plate remains fixed (mostly horizontal or inclined). When the retrieval plate rotates to the highest point with the rotating roller to complete the discharge of debris, it is impossible to adjust the posture to form an effective discharge angle. The debris can only be removed by the centrifugal force generated by the rotation of the rotating roller, which makes it difficult to completely remove the debris from the surface of the retrieval plate. Therefore, when the rotating roller moves down to reset, the debris re-enters the water surface. Multiple retrievals are required to achieve the expected debris removal effect, which significantly reduces the retrieval efficiency and makes it difficult to meet the needs of practical applications.

[0004] Therefore, a debris removal device for groundwater pollution control is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a debris retrieval device for groundwater pollution control, so as to improve the separation effect of debris from the retrieval plate during material discharge, thereby increasing the debris retrieval rate.

[0006] To solve the above-mentioned technical problems, this utility model provides a debris retrieval device for groundwater pollution control, including a support base, a rotating retrieval mechanism, and a linkage component; The bottom wall of the support is provided with a material receiving cavity on one side and an opening for the rotary retrieval mechanism to pass through on the other side. The rotating salvage mechanism includes a rotating roller and multiple salvage plates; The rotating roller is rotatably mounted inside the bearing seat by a driving component and is located above the opening, and has connecting plates arranged in a ring at equal intervals on its outer wall; The salvage plate is movably connected to the connecting plate; The bottom wall of the salvage plate is both parallel and perpendicular to the horizontal plane. The linkage is installed on the inner wall of the support base, and is used to switch the retrieval plate to a vertical state and a horizontal state respectively when the retrieval plate rotates from the lowest point to the highest point and from the highest point to the lowest point.

[0007] Furthermore, a threaded rod is fixedly installed on one side of the salvage plate by a bracket; One end of the threaded rod is threadedly connected to the connecting plate, and a rotating gear is fixedly installed at the end. When the rotating gear rotates, it causes the retrieval plate to rotate relative to the connecting plate; When the rotating gear is not subjected to external force, the retrieval plate and the connecting plate remain relatively fixed under the connection of the threaded rod.

[0008] Furthermore, the linkage includes an outer arc-shaped rack and an inner arc-shaped rack for meshing with the rotating gear; Both the outer arc-shaped rack and the inner arc-shaped rack are fixedly installed inside the bearing seat.

[0009] Furthermore, the width of the outer arc-shaped rack and the inner arc-shaped rack is greater than the thickness of the rotating gear, so that the rotating gear rotates under the relative force of the outer arc-shaped rack or the inner arc-shaped rack, and always meshes with the outer arc-shaped rack or the inner arc-shaped rack when feeding along the axis of the threaded rod.

[0010] Furthermore, the retrieval plate is configured with an L-shaped cavity structure, and the bottom of the retrieval plate is provided with multiple sieve holes.

[0011] Furthermore, a screen is provided on the bottom wall of the inner cavity of the receiving chamber.

[0012] Furthermore, the side of the receiving chamber away from the rotating retrieval mechanism is inclined.

[0013] Furthermore, the inner cavity of the bearing seat has a protrusion in the middle, and the protrusion and the outer wall of the bearing seat surround to form the receiving cavity.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: By setting up a rotating retrieval mechanism including a rotating roller and a retrieval plate, and movably connecting the retrieval plate to the connecting plate on the outer wall of the rotating roller, the bottom wall of the retrieval plate can switch between a parallel state and a vertical state with respect to the horizontal plane. By setting up a linkage component, the retrieval plate can switch to a vertical state when it is at its highest point. In this way, the centrifugal force generated by the rotation of the rotating roller and the auxiliary effect of the gravity of the debris in the vertical posture can be used to greatly enhance the separation effect between the debris and the retrieval plate. This effectively avoids the problems of debris residue caused by the inability to adjust the posture of the fixed retrieval plate in the prior art, as well as the problem of secondary pollution caused by the debris falling back into the water when the rotating roller returns to its original position. This achieves the purpose of effectively improving the separation effect of debris from the retrieval plate during discharge and increasing the debris retrieval rate. Attached Figure Description

[0017] The following is a more detailed description of the debris retrieval device for groundwater pollution control according to the present invention, with reference to the schematic diagrams, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0018] Furthermore, based on the teachings of this specification, those skilled in the art can form new technical solutions through cross-combination of different implementation methods without creating technical contradictions. Such variations should all be considered to fall within the protection scope of this patent.

[0019] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0020] like Figure 1 and Figure 2As shown in the figure, this utility model embodiment proposes a debris retrieval device for groundwater pollution control, including a support base 1, a rotating retrieval mechanism 2, and a linkage component 3.

[0021] The support base 1 has a receiving cavity 11 on one side of its bottom wall and an opening 12 on the other side of its bottom wall for the rotary retrieval mechanism 2 to pass through. That is, the receiving cavity 11 is provided to receive the debris retrieved by the rotary retrieval mechanism 2.

[0022] The rotating salvage mechanism 2 includes a rotating roller 21 and multiple salvage plates 22.

[0023] The rotating roller 21 is rotatably mounted inside the bearing seat 1 by a driving component and is located above the opening 12. Its outer wall has connecting plates 211 arranged in a ring at equal intervals. The retrieval plate 22 is movably connected to the connecting plates 211.

[0024] The rotating roller 21 serves as a power transmission carrier, which can drive the retrieval plate 22 to make circular motion. This enables multi-station cyclic operation with the help of multiple retrieval plates 22, reducing the interval between operations. The two work together to improve the retrieval efficiency of the device, thereby meeting the needs of batch impurity removal in groundwater pollution treatment.

[0025] It should be noted that the bottom wall of the salvage plate 22 is both parallel and perpendicular to the horizontal plane.

[0026] When the salvage plate 22 is in a horizontal state, its bottom wall is parallel to the horizontal plane, which maximizes the scooping area and prevents debris from sliding off the edge of the plate due to the impact of water flow during underwater salvage. When it is in a vertical state, the bottom wall of the salvage plate 22 is perpendicular to the horizontal plane, which can help the debris to quickly detach from the plate by the combined action of gravity and centrifugal force, thus improving the debris removal effect.

[0027] The linkage 3 is disposed on the inner wall of the bearing seat 1, and is used to switch the retrieval plate 22 to a vertical state and a horizontal state respectively when the retrieval plate 22 rotates from the lowest point to the highest point and from the highest point to the lowest point.

[0028] This device is equipped with a rotating retrieval mechanism 2, including a rotating roller 21 and a retrieval plate 22. The retrieval plate 22 is movably connected to the connecting plate 211 on the outer wall of the rotating roller 21, allowing the bottom wall of the retrieval plate 22 to switch between a parallel and a vertical state with respect to the horizontal plane. By setting a linkage 3, the retrieval plate 22 can switch to a vertical state when it is at its highest point. In this way, the centrifugal force generated by the rotation of the rotating roller 21 and the auxiliary effect of the gravity of the debris in the vertical position can be used to greatly enhance the separation effect between the debris and the retrieval plate 22. This effectively avoids the problems of debris residue caused by the fixed retrieval plate 22 not being able to adjust its posture in the prior art, and secondary pollution caused by the debris falling back into the water when it returns to its position as the rotating roller 21 descends. This achieves the purpose of effectively improving the separation effect of debris from the retrieval plate 22 during discharge and increasing the debris retrieval rate.

[0029] In this embodiment, the connection relationship between the retrieval plate 22 and the connecting plate 211 is further defined so that the retrieval plate 22 can rotate flexibly when the attitude needs to be adjusted and remain stable when no adjustment is needed, so as to avoid unexpected attitude deviation from affecting the operation.

[0030] Specifically, a threaded rod 4 is fixedly installed on one side of the salvage plate 22 by a bracket.

[0031] One end of the threaded rod 4 is threadedly connected to the connecting plate 211, and a rotating gear 41 is fixedly installed at the end.

[0032] It should be noted that when the rotating gear 41 rotates, it drives the retrieval plate 22 to rotate relative to the connecting plate 211; and when the rotating gear 41 is not subjected to external force, the retrieval plate 22 and the connecting plate 211 remain relatively fixed under the connection action of the threaded rod 4.

[0033] That is, when the retrieval plate 22 is in a parallel or horizontal state, if the rotating gear 41 is not disturbed by the meshing action, the retrieval plate 22 will not move relative to the connecting plate 211, so as to ensure the stability when retrieving debris.

[0034] In this embodiment, a specific linkage 3 is proposed to cooperate with the rotating gear 41 to realize the switching of the state of the retrieval plate 22.

[0035] Specifically, the linkage 3 includes an outer arc-shaped rack 31 and an inner arc-shaped rack 32 for meshing with the rotating gear 41.

[0036] Both the outer arc-shaped rack 31 and the inner arc-shaped rack 32 are fixedly installed inside the bearing seat 1.

[0037] The outer arc-shaped rack 31 and the inner arc-shaped rack 32 are respectively designed to correspond to different rotation stages of the retrieval plate 22. For example, the outer arc-shaped rack 31 controls the retrieval plate 22 to switch to a vertical state when rotating from the lowest point to the highest point, while the inner arc-shaped rack 32 controls the retrieval plate 22 to switch to a horizontal state when rotating from the highest point to the lowest point. Both are fixed within the support base 1, ensuring a fixed meshing position with the rotating gear 41 and preventing meshing deviation due to rack loosening. This ensures the accuracy of attitude switching, and the double rack design can cover the complete rotation trajectory of the retrieval plate 22, achieving control without blind spots.

[0038] It should be noted that since the retrieval plate 22 and the connecting plate 211 are connected by the threaded rod 4, and the connecting plate 211 is fixedly mounted on the outer wall of the rotating roller 21, when the retrieval plate 22 rotates relative to the connecting plate 211 under the action of the rotation of the threaded rod 4, the threaded rod 4 will carry the retrieval plate 22 to deviate from the connecting plate 211 along its axis. Therefore, in order to prevent the rotating gear 41 from separating when it meshes with the outer arc rack 31 and the inner arc rack 32, the outer arc rack 31 and the inner arc rack 32 are further restricted.

[0039] Specifically, the width of the outer arc-shaped rack 31 and the inner arc-shaped rack 32 is greater than the thickness of the rotating gear 41, so that the rotating gear 41 rotates under the relative force of the outer arc-shaped rack 31 or the inner arc-shaped rack 32, and when feeding along the axis of the threaded rod 4, it always meshes with the outer arc-shaped rack 31 or the inner arc-shaped rack 32 to ensure stability during transmission.

[0040] In other embodiments, the retrieval plate 22 is configured as an L-shaped cavity structure, and the bottom of the retrieval plate 22 is provided with multiple sieve holes.

[0041] Preferably, the bottom wall of the receiving chamber 11 is provided with a screen 14 for draining moisture from the inside of the impurities.

[0042] The receiving chamber 11 is inclined on the side away from the rotating retrieval mechanism 2 to guide debris that has detached from the retrieval plate 22 due to centrifugal force into the receiving chamber 11.

[0043] In this embodiment, the inner cavity of the bearing seat 1 has a protrusion 13, and the protrusion 13 and the outer wall of the bearing seat 1 surround each other to form the receiving cavity 11.

[0044] In practical applications, the support seat 1 of this device can be installed at the end of the hull via a connecting bracket, and the support seat 1 can be suspended above the water surface. The rotating salvage mechanism 2 can then be brought into contact with the water surface, so as to achieve the function of precise debris removal through the drive of the hull.

[0045] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
