Description

Technical Field

[0001] The invention belongs to the technical field of suspended matter filtration, and specifically refers to a suspended matter sedimentation and separation device for sewage treatment. Background Art

[0002] As life becomes more and more affluent, a large amount of sewage is generated in industrial production and daily life, and the sewage often carries suspended matter. In order to prevent sewage from polluting the environment, the sewage is usually filtered before being discharged.

[0003] The existing suspended solids sedimentation and separation equipment for sewage treatment has the following problems:

[0004] Existing suspended matter sedimentation and separation equipment for sewage treatment does not have the ability to detect impurities at the bottom of the sedimentation tank, which in turn affects the sedimentation effect of the sedimentation tank and may even cause sludge to float, thereby reducing the sedimentation tank's filtering effect on suspended matter in sewage. In addition, in order to obtain sufficient sedimentation area and residence time, traditional sedimentation tanks often require a large area. Therefore, they cannot meet the existing demand for the use of sedimentation tanks. Summary of the invention

[0006] The technical scheme adopted in this scheme is as follows: This scheme proposes a suspended matter sedimentation and separation equipment for sewage treatment, including a sedimentation tank, a support column, a slow-speed filtering mechanism and an anti-floating type weight-sensing mechanism. Multiple groups of the support columns are arranged on the bottom wall of the sedimentation tank. The sedimentation tank is open at the upper end. The slow-speed filtering mechanism is arranged on the sedimentation tank. The anti-floating type weight-sensing mechanism is arranged on the support column. The slow-speed filtering mechanism includes a guide mechanism, a filtering mechanism and a locking mechanism. The guide mechanism is arranged on the upper wall of the sedimentation tank, the filtering mechanism is arranged on the guide mechanism, and the locking mechanism is arranged on the bottom wall of the guide mechanism. The anti-floating type weight-sensing mechanism includes a supporting mechanism and a weight measuring mechanism. The supporting mechanism is arranged on the support column, and the weight measuring mechanism is arranged on the supporting mechanism.

[0007] As a further preferred embodiment of the present invention, the guide mechanism includes a guide frame, a guide column, a filter box and a steering groove. The guide frame is arranged on the upper wall of one end of the sedimentation tank, the guide column is arranged through the end of the guide frame away from the upper wall of the sedimentation tank, the filter box is arranged on the bottom wall of the guide column, and the steering groove is symmetrically arranged on the upper walls at both ends of the sedimentation tank, and the steering groove is opened on three sides; the filtering mechanism includes a leak-proof valve, a filter screen, a sedimentation tank, a water inlet pipe, an inclined pipe and a water control valve, a plurality of groups of the leak-proof valves are symmetrically arranged on both sides of the filter box, the leak-proof valves are connected to the filter box, a plurality of groups of the filter screens are arranged on the inner wall of the filter box, and the sedimentation tank is arranged The bottom wall of the filter box between adjacent filter screen plates and the sedimentation tank are arranged with an opening at the upper end; the water inlet pipe is penetrated through the inner wall of the sedimentation tank at one end away from the guide frame, and the water inlet pipe is connected to the leakage-proof valve on the side of the filter box away from the guide frame; the inclined pipe is penetrated through the inner wall of the sedimentation tank at one end close to the guide frame, and the inclined pipe is connected to the leakage-proof valve on the side of the filter box close to the guide frame, and the water control valve is connected to the outside of the water inlet pipe; the locking mechanism includes a locking column and a locking port, a plurality of groups of the locking columns are arranged on the bottom wall of the filter box, a plurality of groups of the locking ports are arranged on the bottom wall of the sedimentation tank, and the locking column is slidably arranged inside the locking port at one end away from the filter box.

[0008] When in use, in the initial state, the locking column is inserted into the locking port, the filter box is placed inside the sedimentation tank, the water inlet pipe and the inclined pipe are connected to the anti-leakage valve respectively, the water control valve is opened, the water inlet pipe and the inclined pipe are connected, the anti-leakage valve is opened, the water inlet pipe and the inclined pipe are connected to the filter box respectively, and the sewage enters the filter box through the water inlet pipe and the anti-leakage valve. Multiple groups of filter screens are arranged inside the filter box, from the water inlet pipe to one end of the inclined pipe, the aperture of the filter screen is set to decrease, and the sewage that enters the filter box through the water inlet pipe is filtered by the filter screen, and the suspended matter in the sewage is intercepted. When the sewage flows through the filter screen, it will encounter a certain resistance, resulting in a reduction in flow rate, so that some of the suspended matter in the sewage is settled inside the sedimentation tank under the action of gravity. As the sewage flows through As the number of filter plates increases, the sewage flow rate gradually slows down, so that more suspended matter in the sewage is precipitated inside the sedimentation tank, thereby reducing the adsorption of suspended matter in the sewage by the filter plates. On the one hand, it can ensure the passability of sewage through the filter plates, and on the other hand, it can reduce the adsorption pressure of the filter plates on suspended matter in the sewage, thereby extending the operation time of the filter plates. The sewage filtered by the filter plates is discharged through the inclined pipe through the leak-proof valve. Due to the inclined setting of the inclined pipe, as the filtered sewage is gradually lifted, the water flow rate will be limited by the resistance and gradually reduce the flow rate, thereby further slowing down the water flow rate at one end of the filter box close to the inclined pipe, making it easier for the sedimentation tank at one end of the filter box close to the inclined pipe to collect more suspended matter, thereby reducing the chance of the filter plate with the smallest aperture being blocked.

[0009] Preferably, the supporting mechanism includes a supporting slider, a supporting plate, a supporting spring, a supporting column, a pressure plate, an annular magnet, a compression plate and a supporting port, the supporting slider is slidably arranged on the outside of the supporting column, the supporting plate is arranged between the supporting sliders, the compression plate is arranged at the end of the supporting column away from the sedimentation tank, the supporting spring is arranged between the compression plate and the supporting plate on the outside of the supporting column, the supporting port is arranged on the bottom wall of the sedimentation tank, the supporting column is arranged on the bottom wall of the filter box, the pressure plate is arranged on the side of the supporting column away from the filter box, the annular magnet is arranged on the outside of the pressure plate, the pressure plate and the supporting plate are arranged in contact with each other, and the annular magnet is adsorbed on the upper wall of the supporting plate by magnetic force; the weighing mechanism includes a distance measuring seat, a distance measuring sensor and a sensing block, multiple groups of the distance measuring seats are arranged on the upper wall of the supporting plate, the distance measuring sensor is arranged on the upper wall of the distance measuring seat, multiple groups of the sensing blocks are arranged on the bottom wall of the sedimentation tank, and the sensing block and the distance measuring sensor are arranged opposite to each other.

[0010] When in use, when the filter box enters the sedimentation tank, the filter box drives the pressure plate through the supporting port through the supporting column and fits with the upper wall of the supporting plate. The annular magnet is adsorbed on the upper wall of the supporting plate. The filter box is fixedly connected to the supporting plate. The connecting part between the water inlet pipe and the inclined pipe and the anti-leakage valve is a telescopic pipe. When the filter box is fully loaded with water, the weight increases. The filter box presses the supporting plate down through the supporting column and the pressure plate. The supporting plate uses the elastic deformation of the supporting spring to slide along the supporting column through the supporting slider to descend. The threshold between the distance sensor and the sensing block is pre-set. The distance sensor detects the distance between the sensing block through the distance measuring end. At this time, the filter box The filter box is in a state without impurities, and the distance between the distance sensor and the induction block is recorded. With the continuous increase of sewage flow inside the filter box, the impurities filtered and precipitated inside the filter box increase, and the weight of the filter box increases. The filter box drives the pressure plate to press the support plate down through the support column. The support plate drives the support slider to slide down along the support column through the deformation of the support spring. The distance between the distance measuring end of the distance measuring sensor and the induction block increases. When the distance between the distance measuring end of the distance measuring sensor and the induction block reaches the preset threshold, the operator needs to clean the filter screen inside the filter box and close the water control valve outside the water inlet pipe. , close the anti-leakage valves on both sides of the filter box, unplug the water inlet pipe and the tilt pipe from the outside of the anti-leakage valve, pull the guide column, the guide column slides along the guide frame to drive the filter box to rise, the annular magnet detaches from the upper wall of the support plate, the locking column is pulled out from the inside of the locking port, the bottom wall of the locking column is level with the bottom wall of the steering groove, rotate the guide column, the guide column rotates along the inner wall of the guide frame to drive the filter box to rotate, the filter box is placed on the bottom wall of the steering groove, the cleaning water pipe is connected to the anti-leakage valve on the side of the filter box close to the smallest aperture filter screen plate, open the anti-leakage valves on both sides of the filter box, and clean water rushes from the small-aperture filter screen plate to the large-aperture filter screen plate for cleaning, and then pull the guide column, The guide column drives the filter box away from the bottom wall of the steering trough, rotates the guide column, drives the filter box to reset, pushes the guide column, drives the filter box to be placed inside the sedimentation tank, the filter box drives the locking column to be inserted into the locking port, the filter box drives the supporting column to pass through the supporting port, the supporting column drives the pressure plate to fit the upper wall of the supporting plate, the annular magnet is adsorbed on the upper wall of the supporting plate, the filter box and the supporting plate resume a fixed connection state, the water inlet pipe and the inclined pipe are respectively inserted into the outside of the anti-leakage valve, the anti-leakage valve is opened, the water inlet pipe and the inclined pipe are connected to the filter box, the water control valve is opened, and the sewage to be treated enters the filter box through the water inlet pipe again for filtration.

[0013] Preferably, the model of the distance measuring sensor is C1-JCS1501.

[0014] The beneficial effects achieved by adopting the above structure are as follows:

[0015] Compared with the prior art, this solution adopts a combination of blocking and decelerating filtration and self-weight monitoring. Through the slow-speed filtering mechanism and the anti-floating weight sensing mechanism, under the coordinated use of the guiding mechanism, the filtering mechanism, the locking mechanism, the supporting mechanism and the weight measuring mechanism, the sewage is blocked layer by layer through multiple sets of filter screens, so that the suspended matter in the sewage can be finely filtered while ensuring the passability of the sewage through the filter screen while avoiding the blockage of the small-aperture filter screen. The real-time monitoring of the distance between the sensing blocks by the distance measuring sensor can indirectly reflect the content of impurities inside the filter box, thereby reminding the operator to clean the impurities inside the filter box in time, thereby ensuring the efficient filtering ability of the filter screen for sewage. Secondly, by setting the inclined pipe at the drainage end, the filtered sewage is prompted to flow to a higher place, further slowing down the flow rate of the sewage, so that the sedimentation tank at one end of the filter box close to the filter screen with the smallest aperture can precipitate more suspended matter, ensuring the minimum aperture. The filter box drives the pressure plate through the supporting port through the supporting column to fit the upper wall of the supporting plate. The annular magnet is adsorbed on the upper wall of the supporting plate. The filter box is fixedly connected to the supporting plate. The connecting part of the water inlet pipe and the inclined pipe and the anti-leakage valve is a telescopic pipe. When the filter box is full of water, the weight increases. The filter box presses down the supporting plate through the supporting column and the pressure plate. The supporting plate slides down along the supporting column through the elastic deformation of the supporting spring through the supporting slider. The threshold between the distance sensor and the sensing block is pre-set. The distance sensor detects the distance between the sensing block through the distance measuring end. At this time, the inside of the filter box is in an impurity-free state. The distance between the distance sensor and the sensing block is recorded. As the sewage flow inside the filter box continues to increase, the impurities filtered and precipitated inside the filter box increase, and the weight of the filter box increases. The filter box drives the pressure plate to press down the supporting plate through the supporting column. The supporting plate drives the supporting slider to slide down along the supporting column through the deformation of the supporting spring, and the distance between the distance measuring end of the distance sensor and the sensing block increases.

[0035] A controller 31 is disposed on the side wall of the guide frame 5 .

[0036] The controller 31 is electrically connected to the distance measuring sensor 29 .

[0037] The model of the distance measuring sensor 29 is C1-JCS1501.

[0038] When in use, in the initial state, the locking column 17 is inserted into the locking port 18, the filter box 7 is placed inside the sedimentation tank 1, the water inlet pipe 13 and the inclined pipe 14 are connected to the anti-leakage valve 10 respectively, the water control valve 15 is opened, the water inlet pipe 13 and the inclined pipe 14 are connected, the anti-leakage valve 10 is opened, the water inlet pipe 13 and the inclined pipe 14 are connected to the filter box 7 respectively, and the sewage enters the filter box 7 through the water inlet pipe 13 and the anti-leakage valve 10. There are multiple groups of filter screens 11 arranged inside the filter box 7, from the water inlet pipe 13 to one end of the inclined pipe 14, the aperture of the filter screen 11 is set to decrease, and the sewage entering the filter box 7 through the water inlet pipe 13 is filtered by the filter screen 11, and the suspended matter in the sewage is intercepted. When the sewage flows through the filter screen 11, it will be subject to a certain resistance, resulting in a reduction in flow rate, so that part of the suspended matter in the sewage is precipitated in the sedimentation tank 12 under the action of gravity;

[0039] Specifically, as the amount of sewage flowing through the filter screen 11 increases, the flow rate of the sewage gradually slows down, so that more suspended matter in the sewage is precipitated inside the sedimentation tank 12, reducing the adsorption of suspended matter in the sewage by the filter screen 11. On the one hand, it can ensure the passability of sewage through the filter screen 11, and on the other hand, it can reduce the adsorption pressure of the filter screen 11 on the suspended matter in the sewage, prolonging the operation time of the filter screen 11.

When the filter box 7 is full of water, the weight increases. The filter box 7 presses the supporting plate 22 down through the supporting column 24 and the pressure plate 25. The supporting plate 22 uses the elastic deformation of the supporting spring 23 to slide down along the supporting column 2 through the supporting slider 21. The threshold between the distance sensor 29 and the induction block 30 is preset, and the controller 31 controls the distance sensor 29 to start. The distance sensor 29 detects the distance through the distance end The distance between the distance sensor 29 and the induction block 30. At this time, the inside of the filter box 7 is in a state without impurities. The distance between the distance sensor 29 and the induction block 30 is recorded. As the sewage flow inside the filter box 7 continues to increase, the impurities filtered and precipitated inside the filter box 7 increase, and the weight of the filter box 7 increases. The filter box 7 drives the pressure plate 25 to press down the support plate 22 through the support column 24. The support plate 22 drives the support slider 21 to slide down along the support column 2 through the deformation of the support spring 23. The distance between the distance measuring end of the distance sensor 29 and the induction block 30 increases. When the distance between the distance measuring end of the distance sensor 29 and the induction block 30 reaches a preset threshold, the operator needs to clean the filter screen 11 inside the filter box 7;
