Description

Technical Field

[0001] The utility model relates to the technical field of water environment treatment, in particular to a suspended solids separation device for water environment treatment. Background Art

[0002] Water environment remediation refers to the restoration and improvement of rivers, bays, lakes, ponds, and other areas where water pollution fails to meet control targets. It encompasses the entire process, from pollution control to water quality improvement, and finally ecological and economic restoration. When polluted water quality needs to be remediated, water sampling and testing are necessary to identify specific pollutants for targeted treatment. After sampling, wastewater is separated and filtered to remove suspended solids, preventing them from impacting water pollution detection.

[0003] Suspended solids in water pollution usually refer to solid matter suspended in the water. These substances may include water-insoluble inorganic matter, organic matter, mud, sand, clay, microorganisms, fibers, plastic products, tree branches and wood blocks, etc. Existing suspended solids separation devices for water environment treatment usually filter the sewage to be filtered through a layer of filter screen to separate it. If the pore size of the filter screen is large, fine suspended solids may easily pass through the filter screen, and it will not be able to effectively intercept suspended solids of all sizes, resulting in the effluent water quality still containing a large amount of suspended solids, affecting the final water quality test results. If the pore size of the filter screen is too small, although more suspended solids can be intercepted, it is also very easy to cause the filter screen to quickly clog, affecting the filtration efficiency and water flow rate, and requiring frequent cleaning or replacement of the filter screen, increasing maintenance costs.

[0015] The beneficial effects of the present invention are as follows: the present invention provides a floating matter separation device for water environment treatment, which has the following beneficial effects.

[0016] (1) Multiple layers of filter screens are installed in the separation cylinder, and the pore size of the filter screens gradually decreases from the inside to the outside, so that the filter screen in the center filters out larger floaters, and gradually filters out smaller floaters from the outside. This can effectively intercept almost all floaters, enhance the accuracy of the final water quality test, and meet the needs of water environment management.

The plug on the motor drive shaft moves downward under the action of the lifting device and is inserted into the slot of the cover plate. When the motor is started, the drive shaft drives the cover plate to rotate, and then drives the multiple filter screens to rotate synchronously. When the motor drives the filter screen to rotate, the water in the filter screen will be thrown to the wall of the separation cylinder by the centrifugal force, and then flow down along the cylinder wall along the guide plate to the liquid outlet, and enter the collection box through the control valve. The filtered water in the collection box is then sent for testing, which greatly improves the efficiency of floating matter separation, saves labor costs, and achieves better separation effect.

[0018] (3) The detachable connection between multiple filter screens facilitates timely removal of blocked or damaged filter screens for cleaning or replacement, greatly improving the efficiency of filter installation and replacement.

The operation is simple and highly practical.

[0019] (4) The setting of the lifting device can quickly and accurately insert the plug on the motor drive shaft into the slot of the cover plate according to the actual work needs, realizing the automated operation of floating object separation, greatly improving the separation efficiency and ensuring the separation quality.

DETAILED DESCRIPTION

[0028] The present invention is further described below with reference to the accompanying drawings and specific embodiments to facilitate understanding of the present invention. The methods used in the present invention are conventional methods unless otherwise specified; the raw materials and devices used are conventional commercially available products unless otherwise specified.

[0029] Example:

[0030] like Figures 1 to 7 As shown, the utility model provides a suspended solids separation device for water environment treatment, including a separation cylinder 1 and a filter 2. The separation cylinder 1 is detachably mounted on a fixing frame 3, so that the separation cylinder 1 can be removed at any time according to actual needs. A plurality of the filter screens 2 are rotatably mounted on the interior of the separation cylinder 1 through a bearing 24. Specifically, the outer ring of the bearing 24 is fixedly connected to the separation cylinder 1, and the inner ring of the bearing 24 is fixedly connected to the outermost filter screen 2 through a bolt 14. The plurality of filter screens 2 are mutually sleeved and detachably connected. The aperture of 2 gradually decreases from the inside to the outside, and a cover plate 4 is fixedly installed on the outermost filter screen 2. The diameter of the cover plate 4 is larger than the diameter of the separation cylinder 1. The cover plate 4 is located above the separation cylinder 1. A driving device is connected to the cover plate 4, and the driving device is used to drive the multiple filter screens 2 to rotate. A lifting device 5 is provided on the fixed frame 3, and the lifting device 5 is used to adjust the distance between the driving device and the cover plate 4 to ensure that the cover plate 4 can be smoothly opened when adding sewage to be filtered and cleaning the filter screen 2, without affecting the above operations.

[0031] Furthermore, the driving device includes a motor 6 and a locking component, the motor 6 is fixedly installed in the middle position of the top of the fixing frame 3, and the locking component is used to connect the motor 6 and the cover plate 4.

[0032] Furthermore, the locking component includes an insert 7 and a slot 8. Both the insert 7 and the slot 8 have rectangular cross-sections. The insert 7 is fixedly mounted on the drive shaft 9 of the motor 1 6. The slot 8 is defined at the top of the cover plate 4. The insert 7 is inserted into the slot 8 and rotated to lock. The rotation direction of the drive shaft 9 aligns with the rotational locking direction of the insert 7. Specifically, the motor 1 6 is a servo motor. The motor 1 6 drives the drive shaft 9 to rotate counterclockwise, which in turn drives the cover plate 4 to rotate counterclockwise, ultimately driving the filter screen 2 to rotate. Centrifugal force in the sewage in the filter screen 2 filters out suspended matter.

[0033] Furthermore, the fixing frame 3 includes a fixing rod 31, a connecting rod 32, a cross rod 33 and a base plate 34. The two fixing rods 31 are vertically fixed to the base plate 34 by bolts 25. Not only is the fixation more secure, but the faulty motor 2 51 can also be replaced in time. The connecting rod 32 is sleeved in the corresponding fixing rod 31 and is slidably connected to the fixing rod 31. The cross rod 33 is fixedly installed between the tops of the two connecting rods 32, and the motor 1 6 is fixedly installed at the bottom of the cross rod 33. The lifting device 5 includes motor 2 51, a fixing block 52 and a screw 53. The motor 2 51 is fixedly installed at the bottom of the fixing rod 31. One end of the screw 53 is fixedly connected to the motor 2 51, and the other end passes through the fixing block 52 at the bottom of the connecting rod 32 and is threadedly connected to the fixing block 52.

[0034] When it is necessary to separate the suspended matter from the sewage entering the separation cylinder 1, the cover plate 4 is fixedly installed on the outermost filter screen 2, and the motor 2 51 is started. The rotation of the motor 2 51 drives the rotation of the screw 53. Since the fixing block 52 at the bottom of the connecting rod 32 is threadedly connected to the screw 53, the rotation of the screw 53 drives the fixing block 52 to move up and down, and then drives the connecting rods 32 on both sides to move up and down along the corresponding fixing rods 31, and finally drives the motor 1 6 on the cross bar 33 to move downward, so that the plug block 7 on the drive shaft 9 is just inserted into the slot 8 of the cover plate 4. The motor 1 6 drives the cover plate 4 to rotate counterclockwise. At this time, the plug block 7 is locked with the cover plate 4, driving the rotation of the multi-layer filter screen 2, thereby separating the suspended matter from the sewage. The separation method is simple, efficient and effective.

[0035] Furthermore, the limit plate 10 is fixedly mounted on the top of the screw rod 53. The setting of the limit plate 10 can prevent the connecting rod 32 from being separated from the fixing rod 31 and affecting the normal operation of the motor 6.

[0036] Furthermore, a threaded hole 11 is provided on the top of each filter screen 2, and an extension plate 12 is fixedly installed on the top of each filter screen 2. A plurality of through holes 13 are provided on the extension plate 12. The through holes 13 on the outer filter screen 2 correspond to the threaded holes 11 on the inner filter screen 2, and a bolt 14 passes through the through hole 13 and is threadedly connected to the threaded hole 11.

[0037] The outermost filter screen 2 is fixedly mounted on the bearing 24 by means of a bolt 14, and each subsequent filter screen 2 is fixed to the filter screen 2 on its outer side by means of a bolt 14, thereby achieving a detachable connection between multiple filter screens 2 for easy cleaning or replacement.

[0038] Furthermore, a guide plate 15 is fixedly installed in the separation cylinder 1 below the filter screen 2, and a liquid outlet 16 is provided at the lowest end of the guide plate 15. A control valve 17 is installed on the liquid outlet 16, and a collection box 18 is provided below the liquid outlet 16.

[0039] The setting of the guide plate 15 allows the separated sewage to enter the collection box 18 along the direction of the guide plate 15, preparing for subsequent sewage water quality testing, which greatly improves the accuracy of the detection.

[0040] Furthermore, connecting shafts 19 are vertically fixedly installed on the extension plates 12 on both sides of the outermost filter 2, one side of the cover plate 4 is rotatably connected to one of the connecting shafts 19, a circular hole 20 is provided on the other side of the cover plate 4, and a second threaded hole is provided on the other connecting shaft 19, and a second bolt passes through the circular hole 20 and is fixedly connected to the second threaded hole.

[0041] When sewage needs to be passed through the water pipe into the separation drum 1, the cover plate 4 is rotated horizontally about one of the connecting shafts 19, thereby opening the top of the separation drum 1 and pouring the sewage to be filtered into the separation drum 1. Alternatively, a liquid inlet can be directly provided on the cover plate 4, allowing liquid to be introduced without opening the cover plate 4. In this embodiment, the cover plate 4 is opened. After the sewage to be filtered is poured into the separation drum 1, the cover plate 4 is rotated so that the circular hole 20 on the cover plate 4 corresponds to the second threaded hole on the top of the other connecting shaft 19. The cover plate 4 is fixed in position using bolt 2, and then the cover plate 4 is rotated using motor 1 6 to perform the suspended solids separation operation.

[0042] When too much floating matter sticks to the filter 2 and causes the filter 2 to be blocked, the brush 26 can be rotated and locked to the drive shaft 9 through the same structure as the cover 4. At this time, the cover 4 is fully opened around the connecting shaft 19, and the brush 26 is extended into the filter 2 to clean it. Since multiple filter screens 2 are detachably connected, the brush 26 that matches the diameter of the filter 2 can be replaced for cleaning. The cleaning method is simple and efficient.

[0043] Furthermore, a fixing plate 1 21 is installed on the fixing frame 3, and a fixing plate 2 22 is fixedly installed on the outer side of the separation cylinder 1. The fixing plate 1 21 and the fixing plate 2 22 are fixedly connected by a bolt 3 23, so that the entire separation cylinder 1 can be removed for cleaning in time according to actual cleaning and inspection needs. The operation is simple and practical.

[0044] The working principle of this embodiment is as follows:

[0045] First, open the cover 4 and send the sewage to be filtered into the interior of the separation cylinder 1 through the water pipe, then close the cover 4, use bolt 2 to fix the cover 4 to the outermost filter screen 2, and the outermost filter screen 2 is fixedly installed on the inner ring of the bearing 24 by bolt 14, and then start motor 2 51. Motor 2 51 drives the screw 53 to rotate, and then drives the fixed block 52 on the connecting rod 32 to move downward along the screw 53, thereby driving motor 1 6 on the cross bar 33 to move downward, so that the insert block 7 at the bottom of the motor 1 6 drive shaft 9 is just inserted into the slot 8 of the cover 4, and start motor 1 6. The motor 1 6 drives the cover 4 to rotate counterclockwise, and then drives the multi-layer filter screen 2 to rotate counterclockwise. Through the action of centrifugal force, the suspended matter and sewage are separated, and the sewage flows along the wall of the separation cylinder 1 to the liquid outlet 16 under the action of the guide plate 15. The control valve 17 is opened to allow the separated sewage to flow into the collection box 18, preparing for subsequent water quality testing.
