Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a solid-liquid separation system. Background Technology
[0002] In the process of wastewater treatment, separating solid impurities from wastewater is one of the important steps. Currently, traditional solid-liquid separation devices often suffer from low filtration efficiency and easy clogging due to their simple structure, and lack automated waste discharge functions. For example, fixed filters require frequent shutdowns to clean impurities, making continuous separation impossible and resulting in low separation efficiency. To solve the above problems, this utility model provides a solid-liquid separation system. Utility Model Content
[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a solid-liquid separation system that allows multiple separation grids to move alternately between a flow chamber and a waste discharge chamber. After trapping impurities, the separation grids automatically transfer to the waste discharge chamber to empty the trapped impurities, while other separation grids move into the flow chamber to trap impurities, enabling continuous operation and improving separation efficiency.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a solid-liquid separation system, comprising:
[0005] The box body is divided into a flow chamber and a waste discharge chamber. Wastewater flows from the inside of the flow chamber, and the lower end of the waste discharge chamber is connected to the outside.
[0006] Multiple separation plates move alternately between the flow chamber and the waste discharge chamber. When they are inside the flow chamber, they can trap solid impurities from the water flow, and when they move to the waste discharge chamber, they can dump the trapped solid impurities into the waste discharge chamber.
[0007] Preferably, a plurality of the separation grid plates are fixedly mounted on a rotating shaft, which is rotatably mounted inside the housing and driven by a motor mounted on the housing to rotate intermittently by a specified angle.
[0008] Preferably, when the grid plate traps solid impurities, the angle between its upper side surface and the circumferential surface of the rotating shaft is an acute angle.
[0009] Preferably, when the grid plate traps solid impurities, it has multiple protruding strips fixedly connected to the side facing the sewage flow.
[0010] Preferably, a shaking component is provided between the separation grid plate and the inner wall of the housing, so that the separation grid plate shakes continuously when the shaft rotates.
[0011] Preferably, the jitter component includes:
[0012] Two moving blocks are respectively fixedly installed at both ends of the separation grid plate on the side away from the rotating shaft;
[0013] Multiple fixing blocks are fixedly installed on the inner walls of both sides of the housing, and the multiple fixing blocks on the same plane are all located above the axis of rotation and distributed along the movement trajectory of the moving block.
[0014] Preferably, the motor shaft of the motor extends into the interior of a slot provided on the end face of the rotating shaft and is fixedly connected to a rotating plate. A fixing plate adapted to the rotating plate is fixedly connected to the wall of the slot. A spring is fixedly connected between the side of the rotating plate facing the direction of rotation and the fixing plate.
[0015] Preferably, the flow cavity has multiple clearance openings adapted to the separation grid plate on the side wall below the rotating shaft, and a sealing membrane is provided on the inner side of the clearance opening, and the size of the sealing membrane is larger than the size of the clearance opening. One side of the sealing membrane is fixedly connected to the inner side wall of the flow cavity.
[0016] Preferably, a plurality of sealing strips are fixedly installed on the rotating shaft.
[0017] Preferably, a guide plate is fixedly installed at the lower opening of the waste discharge chamber, and the height of the end of the guide plate away from the flow chamber is lower than the height of the other end.
[0018] The beneficial effects of this utility model are as follows:
[0019] This invention, through the setting of a rotating shaft and separation grids, enables the rotating shaft to drive the separation grids to rotate, so that multiple separation grids move alternately between the flow chamber and the waste discharge chamber, thereby intercepting solid impurities in the sewage. At the same time, when the grids are performing interception work, the angle between the upper side of the grid and the rotating shaft is an acute angle, which, together with the convex strips set on the grids, can make the interception effect better.
[0020] This invention, through the arrangement of a moving block, a fixed block, and a spring, enables the separation grid plate to vibrate when the rotating shaft drives it to rotate. Simultaneously, with the reset effect of the spring, impurities on the separation grid plate can be better poured into the waste discharge chamber when it rotates into the waste discharge chamber.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] This invention provides a solid-liquid separation system, such as... Figures 1 to 6 As shown.
[0032] Example 1:
[0033] A solid-liquid separation system includes a housing 1. The interior of the housing 1 is divided into a flow chamber and a waste discharge chamber. The upper end of the flow chamber is provided with multiple water inlet pipes, and the lower end of the flow chamber is provided with a drain outlet. Wastewater enters the interior of the flow chamber through the water inlet pipes and is then discharged through the drain outlet. A rotating shaft 3 is rotatably mounted inside the housing 1. Multiple separation grids 2 are fixedly mounted on the rotating shaft 3. The multiple separation grids 2 are distributed along the axis of the rotating shaft 3. The rotating shaft 3 is driven by a motor 4 mounted on the housing 1. The motor 4 drives the rotating shaft 3 to rotate intermittently, and each time the motor 4 drives the rotating shaft 3 to rotate, it will rotate by a specified angle. This angle is adapted to the number of separation grids 2 (for example, if there are three separation grids 2, the motor 4 will drive the rotating shaft 3 to rotate 120 degrees each time).
[0034] The rotating shaft 3 drives multiple separating grid plates 2 to move alternately between the flow chamber and the waste discharge chamber. When the separating grid plate 2 is located inside the waste discharge chamber and traps solid impurities in the sewage, the angle between the upper side of the separating grid plate 2 and the rotating shaft 3 is an acute angle, which can prevent the trapped impurities from sliding off the separating grid plate 2.
[0035] Multiple protrusions 5 are fixedly connected to the upper side of the separation grid plate 2 that traps solid impurities, which can further increase the trapping effect of solid impurities. The rotating shaft 3 drives the separation grid plate 2 to rotate, which can move the separation grid plate 2 located inside the flow chamber to the inside of the waste discharge chamber. The solid impurities trapped on it are poured out by gravity. A guide plate 11 is fixedly installed at the lower opening of the waste discharge chamber. The height of the end of the guide plate 11 away from the flow chamber is lower than the height of the other end, which can guide the solid impurities falling on it and make them better discharged.
[0036] Example 2:
[0037] Based on Embodiment 1, in order to avoid solid impurities remaining on the separation grid plate 2, a shaking component is provided between the separation grid plate 2 and the inner wall of the housing 1. When the rotating shaft 3 rotates, the separation grid plate 2 will shake continuously, so that the separation grid plate 2 can better dump the solid impurities on it.
[0038] The shaking component includes two moving blocks 6, which are fixedly installed at both ends of the separating grid plate 2 away from the rotating shaft 3. Multiple fixing blocks 7 are fixedly connected to both sides of the inner side wall of the housing 1. The multiple fixing blocks 7 located on the same side wall are all located above the axis of the rotating shaft 3 and distributed along the movement trajectory of the moving blocks 6. When the rotating shaft 3 drives the separating grid plate 2 to rotate, the moving blocks 6 and the multiple fixing blocks 7 will continuously collide.
[0039] The motor shaft of motor 4 extends into the cavity 12 provided on the end face of rotating shaft 3 and is fixedly connected to rotating plate 13. A fixed plate 14 adapted to rotating plate 13 is fixedly connected to the groove wall of cavity 12. A spring 8 is fixedly connected between the side of rotating plate 13 facing the rotation direction and fixed plate 14. When moving block 6 collides with fixed block 7, spring 8 will be compressed by force. When spring 8 is compressed to the limit, moving block 6 will pass the current fixed block 7. At this time, spring 8 will start to stretch. This process is repeated continuously. When rotating shaft 3 rotates, it can cause separation grid plate 2 to vibrate rapidly, so that impurities on separation grid plate 2 can be better guided into the waste discharge chamber.
[0040] Example 3:
[0041] The flow chamber has multiple clearance openings on the side wall below the rotating shaft 3 that are adapted to the separation grid plate 2. A sealing membrane 9 is provided on the inner side of the clearance opening. The sealing membrane 9 is made of elastic material and its size is larger than that of the clearance opening. One side of the sealing membrane 9 is fixedly connected to the inner side wall of the flow chamber. Under its own elastic force, the sealing membrane 9 stably covers the inner side of the clearance opening. A sealing strip 10 is fixedly connected to the rotating shaft 3. The sealing strip 10 and the sealing membrane 9 cooperate with each other to prevent sewage leakage.
[0042] Motor 4 drives shaft 3 to rotate intermittently. After the separation grid plate 2 intercepts impurities in the flow chamber, it enters the waste discharge chamber to dump solid impurities. After dumping solid impurities in the waste discharge chamber, the separation grid plate 2 enters the flow chamber through the clearance port covered by sealing membrane 9, thus realizing continuous interception and waste discharge cycle. At the same time, the sealing strip 10 rotates with shaft 3 to fill the gap between shaft 3 and the side wall of flow chamber to prevent sewage leakage.
[0043] 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.
