Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a solid-liquid separation device for treating heavy metal wastewater. Background Technology

[0002] Treating heavy metal wastewater is essential for protecting the ecological environment and maintaining ecological balance. Heavy metal wastewater treatment typically involves multiple stages, including pretreatment, main treatment, and post-treatment, with solid-liquid separation being a crucial step. In the pretreatment stage, solid-liquid separation can remove large suspended solids, impurities, and some heavy metal precipitates from the wastewater, reducing the burden on subsequent treatment processes.

[0003] A search revealed a utility model patent with Chinese patent publication number CN220968398U, which discloses a solid-liquid separation device for treating heavy metal wastewater. The device includes a tank, and a removal mechanism is installed on the tank wall. The removal mechanism is composed of an electric telescopic rod, a honeycomb cylinder A, a connecting plate, a connecting rod, a discharge trough, an arc-shaped cover, and a fixing plate. A set of symmetrical fixing plates is welded to the tank wall, and an electric telescopic rod is bolted to the top of the fixing plate. A connecting plate is installed at the output end of the set of electric telescopic rods.

[0004] In actual operation, the aforementioned device requires the honeycomb cylinder A to be raised to a designated position before the arc-shaped cover can be opened to clean the accumulated solids inside. However, this cleaning process is time-consuming, significantly reducing the effective time the device can actually be used to treat heavy metal wastewater, thus adversely affecting the overall processing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a solid-liquid separation device for treating heavy metal wastewater, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solid-liquid separation device for treating heavy metal wastewater, comprising a guide frame, a movable component installed outside the guide frame, the movable component comprising a support plate fixedly connected to the outer wall of one side of the guide frame, the upper half of the support plate being inclined, a mounting column rotatably connected to one end of the top of the support plate, two equally spaced extension rods fixedly connected to the outer circumference of the mounting column, both extension rods being parallel to the upper half of the support plate, a universal joint fixedly connected to the ends of the two extension rods that are far apart from each other, and a motor fixedly installed on the outer wall of the top of the support plate, the output end of the motor being coaxially fixed with the mounting column.

[0007] As a further preferred embodiment of this technical solution, a connecting frame is rotatably connected to one end of each of the two universal joints, and a honeycomb barrel is rotatably connected inside each of the two connecting frames.

[0008] This design allows for the alternating use of two honeycomb barrels, ensuring that once impurities are collected to a certain extent, they can be put into operation more quickly without affecting the processing work due to impurity cleaning. Starting the motor on the outside of the support plate causes the mounting column to rotate half a turn, switching the positions of the two extension rods outside the mounting column. Wastewater supply only needs to be stopped for a very short time, minimizing downtime. Furthermore, the extension rods are connected to the connecting frame via a universal joint. The universal joint has multi-directional rotation characteristics, automatically adjusting its angle as the extension rod drives the connecting frame to rotate, ensuring that the honeycomb barrels always maintain an upward-facing opening while being rotated under gravity.

[0009] As a further preferred embodiment of this technical solution, an acceleration component is installed inside the support plate. The acceleration component includes an installation groove opened inside the support plate. A horizontally arranged limiting rod is fixedly connected inside the installation groove. A movable seat is slidably sleeved on the outside of the limiting rod. A second motor is fixedly installed on the inner wall of the top of the installation groove. A horizontally arranged transmission rod is fixedly connected to the output end of the second motor. A connecting rod is rotatably connected to the movable end of the transmission rod. The movable end of the connecting rod is rotatably connected to the movable seat.

[0010] Start the second motor inside the installation slot. The second motor drives the transmission rod to rotate. The transmission rod drives the moving seat to move back and forth along the limit rod through the connecting rod. The sleeve rod will move synchronously with the moving seat. The sleeve rod can drive the honeycomb barrel and the connecting frame to swing back and forth at the bottom of the universal joint through the extension plate. The solids inside the honeycomb barrel stay in place under the action of inertia. The mesh of the honeycomb barrel is no longer blocked, so that the wastewater can be filtered faster.

[0011] As a further preferred embodiment of this technical solution, a fixed rod is slidably inserted inside the movable seat. The end of the fixed rod away from the guide frame is provided with a thread, and the threaded part of the fixed rod forms a transmission engagement with the movable seat. A horizontally arranged sleeve rod is slidably inserted inside the movable seat. The end of the fixed rod near the guide frame is fixedly connected to the sleeve rod. A groove is opened at the end of the sleeve rod near the guide frame. A vertically arranged extension plate is fixedly connected to the side of the outer circumference of the two honeycomb barrels that are far apart from each other. One of the extension plates is located inside the groove at the end of the sleeve rod.

[0012] As a further preferred embodiment of this technical solution, a flow guide plate is fixedly connected to the outside of the flow guide frame, and the flow guide plate is arranged in a funnel shape.

[0013] As a further preferred embodiment of this technical solution, a reinforcing frame is fixedly connected to the outer wall of the support plate on the side away from the guide frame.

[0014] As a further preferred embodiment of this technical solution, the first motor is a servo motor.

[0015] This utility model provides a solid-liquid separation device for treating heavy metal wastewater, which has the following beneficial effects:

[0016] (1) By setting a moving component, this utility model enables two honeycomb barrels to be used alternately, ensuring that after a certain amount of impurities are collected, they can be put into operation more quickly, and the processing work will not be affected by the impurity cleaning work. The motor one outside the support plate is started, and the output end of the motor one drives the mounting column to rotate half a turn. The positions of the two extension rods outside the mounting column are replaced, and the wastewater only needs to be stopped for a very short time, without delaying too much working time. In addition, the extension rods are connected to the connecting frame through a universal joint. The universal joint has multi-directional rotation characteristics. When the extension rod drives the connecting frame to rotate, it can automatically adjust the angle, which can ensure that the honeycomb barrel can always keep the opening facing upward when it is driven to rotate under the action of gravity.

[0017] (2) By setting up an acceleration component, the second motor inside the mounting slot is started. The second motor drives the transmission rod to rotate. The transmission rod drives the moving seat to move back and forth along the limit rod through the connecting rod. The sleeve rod will move synchronously with the moving seat. The sleeve rod can drive the honeycomb barrel and the connecting frame to swing back and forth at the bottom of the universal joint through the extension plate. The solid material inside the honeycomb barrel stays in place under the action of inertia. The mesh of the honeycomb barrel is no longer blocked, so that the wastewater can be filtered faster.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 4 As shown in this embodiment, a solid-liquid separation device for treating heavy metal wastewater includes a guide frame 1. A movable component 5 is installed outside the guide frame 1. The movable component 5 includes a support plate 501 fixedly connected to the outer wall of one side of the guide frame 1. The upper half of the support plate 501 is set in an inclined state. A mounting column 502 is rotatably connected to one end of the top of the support plate 501. Two equally spaced extension rods 503 are fixedly connected to the outer circumference of the mounting column 502. Both extension rods 503 are parallel to the upper half of the support plate 501. A universal joint 504 is fixedly connected to the ends of the two extension rods 503 that are far apart from each other. A motor 505 is fixedly installed on the top outer wall of the support plate 501. The output end of the motor 505 is coaxially fixed with the mounting column 502.

[0025] Each of the two universal joints 504 has a connecting bracket 3 rotatably connected to one end of its bottom, and each of the two connecting brackets 3 has a honeycomb barrel 4 rotatably connected inside its interior.

[0026] The motor 505 outside the support plate 501 is started. The output of the motor 505 drives the mounting column 502 to rotate half a turn. The positions of the two extension rods 503 outside the mounting column 502 are changed. The wastewater supply only needs to be stopped for a very short time, which will not delay too much working time. Furthermore, the extension rods 503 are connected to the connecting frame 3 through the universal joint 504. The universal joint 504 has multi-directional rotation characteristics. When the extension rods 503 drive the connecting frame 3 to rotate, it can automatically adjust the angle, which can ensure that the honeycomb barrel 4 can always keep the opening facing upward when it is driven to rotate under the action of gravity.

[0027] like Figure 2 and Figure 3 As shown, an acceleration component 6 is installed inside the support plate 501. The acceleration component 6 includes an installation groove 601 opened inside the support plate 501. A horizontally set limiting rod 602 is fixedly connected inside the installation groove 601. A movable seat 603 is slidably sleeved on the outside of the limiting rod 602. A second motor 606 is fixedly installed on the inner wall of the top of the installation groove 601. A horizontally set transmission rod 605 is fixedly connected to the output end of the second motor 606. A connecting rod 604 is rotatably connected to the movable end of the transmission rod 605. The movable end of the connecting rod 604 is rotatably connected to the movable seat 603.

[0028] A fixed rod 607 is slidably inserted inside the movable seat 603. The end of the fixed rod 607 away from the guide frame 1 is provided with a thread, and the threaded part of the fixed rod 607 forms a transmission engagement with the movable seat 603. A horizontally arranged sleeve rod 608 is slidably inserted inside the movable seat 603. The end of the fixed rod 607 near the guide frame 1 is fixedly connected to the sleeve rod 608. A groove is opened at the end of the sleeve rod 608 near the guide frame 1. A vertically arranged extension plate 609 is fixedly connected to the side of the outer circumference of the two honeycomb barrels 4 that are far apart from each other. One of the extension plates 609 is located inside the groove at the end of the sleeve rod 608.

[0029] The second motor 606 inside the mounting slot 601 is started. The second motor 606 drives the transmission rod 605 to rotate. The transmission rod 605 drives the moving seat 603 to move back and forth along the limit rod 602 through the connecting rod 604. The sleeve rod 608 will move synchronously with the moving seat 603. The sleeve rod 608 can drive the honeycomb barrel 4 and the connecting frame 3 to swing back and forth at the bottom of the universal shaft 504 through the extension plate 609. The solids inside the honeycomb barrel 4 stay in place under the action of inertia, and the mesh of the honeycomb barrel 4 is no longer blocked, so that the wastewater can be filtered faster. After a period of treatment, the second motor 606 is stopped. The fixing rod 607 is connected to the threaded hole of the moving seat 603 through the thread. The fixing rod 607 is driven to rotate by the knob. Under the action of the thread, the fixing rod 607 moves away from the honeycomb barrel 4 along the threaded hole of the moving seat 603, and the honeycomb barrel 4 is no longer obstructed.

[0030] like Figure 1 and Figure 2 As shown, a diversion plate 2 is fixedly connected to the outside of the diversion frame 1. The diversion plate 2 is set in a funnel shape. The water dripping from the honeycomb bucket 4 away from the diversion frame 1 will be received by the diversion plate 2 to avoid pollution to the surrounding area.

[0031] like Figure 1 and Figure 2 As shown, a reinforcing frame 506 is fixedly connected to the outer wall of the support plate 501 on the side away from the guide frame 1, which helps to improve the overall strength of the support plate 501.

[0032] like Figure 1 and Figure 2 As shown, motor 505 is a servo motor, which has a self-locking property, thus ensuring that the position of mounting post 502 will not change arbitrarily after adjustment.

[0033] This utility model provides a solid-liquid separation device for treating heavy metal wastewater, the specific working principle of which is as follows:

[0034] When the device is working, the heavy metal wastewater enters the lower honeycomb barrel 4 through the pipe inside the support plate 501. The solids are intercepted, while the liquid wastewater passes through the mesh of the honeycomb barrel 4 and falls into the guide frame 1. Then it flows to another place through the outlet at the bottom of the guide frame 1.

[0035] During this period, the second motor 606 inside the mounting slot 601 is started. The second motor 606 drives the transmission rod 605 to rotate. The transmission rod 605 drives the moving seat 603 to move back and forth along the limit rod 602 through the connecting rod 604. The sleeve rod 608 will move synchronously with the moving seat 603. The sleeve rod 608 can drive the honeycomb barrel 4 and the connecting frame 3 to swing back and forth at the bottom of the universal joint 504 through the extension plate 609. The solids inside the honeycomb barrel 4 stay in place under the action of inertia, and the mesh of the honeycomb barrel 4 is no longer blocked, so that the wastewater can be filtered faster. After a period of treatment, the second motor 606 is stopped. The fixing rod 607 is connected to the threaded hole of the moving seat 603 through the thread. The fixing rod 607 is driven to rotate by the knob. Under the action of the thread, the fixing rod 607 moves away from the honeycomb barrel 4 along the threaded hole of the moving seat 603, and the honeycomb barrel 4 is no longer obstructed.

[0036] The motor 505 outside the support plate 501 is started. The output of the motor 505 drives the mounting column 502 to rotate half a turn. The positions of the two extension rods 503 outside the mounting column 502 are changed. The wastewater supply only needs to be stopped for a very short time, which will not delay too much working time. Furthermore, the extension rods 503 are connected to the connecting frame 3 through the universal joint 504. The universal joint 504 has multi-directional rotation characteristics. When the extension rods 503 drive the connecting frame 3 to rotate, it can automatically adjust the angle, which can ensure that the honeycomb barrel 4 can always keep the opening facing upward when it is driven to rotate under the action of gravity.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
