Description

Technical Field

[0001] This utility model relates to a sewage treatment tank, and more particularly to a solid-liquid separation type sewage treatment tank. Background Technology

[0002] Solid-liquid separation wastewater treatment uses chemical or physical methods to separate impurities from wastewater, enabling the discharged wastewater to meet environmental emission standards. Chemical methods mainly involve adding chemical agents to the wastewater to coagulate impurities and allow them to settle under gravity, thus achieving solid-liquid separation. This method can effectively remove impurities and purify wastewater.

[0003] Currently, solid-liquid separation of wastewater is carried out in wastewater treatment ponds. This is done by discharging wastewater into the ponds and adding flocculants for settling. However, after the solid-liquid separation is completed and the precipitated impurities are discharged, some impurities tend to adhere to the bottom of the ponds and cannot be completely removed. This requires subsequent cleaning, which is extremely inconvenient.

[0004] Therefore, there is an urgent need to provide a solid-liquid separation wastewater treatment tank that can remove impurities. Utility Model Content

[0005] In order to overcome the shortcomings of existing sewage treatment ponds, where some impurities tend to adhere to the bottom of the pond when the sediment is discharged, making it impossible to completely remove them and requiring subsequent cleaning operations, which is extremely inconvenient, this utility model provides a solid-liquid separation sewage treatment pond that can remove impurities.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a solid-liquid separation wastewater treatment tank, comprising a collection tank, two symmetrically distributed slide rails fixedly connected to the collection tank, a baffle slidably mounted on both slide rails, mounting plates on both sides of the collection tank, a water pump mounted on the mounting plate, a water pipe mounted on the water pump, a support frame fixedly connected inside the collection tank, a first motor mounted on the support frame, an agitator for stirring wastewater mounted on the output shaft of the first motor, a pressure plate slidably mounted on the agitator, a first elastic element for resetting the pressure plate sleeved on the pressure plate, a second motor mounted on the collection tank, and a scraper mounted on the output shaft of the second motor.

[0007] As a preferred embodiment of this utility model, a guide plate is connected and communicated on the water collection tank.

[0008] As a preferred embodiment of this utility model, a limiting frame is fixedly connected inside the water collection tank, and a storage hopper for storing flocculant is provided on the limiting frame. A guide rod is slidably provided on the storage hopper, and a push plate for blocking the discharge port of the storage hopper is fixedly connected to the right end of the guide rod. A second elastic element is sleeved on the guide rod to reset the push plate.

[0009] As a preferred embodiment of this utility model, the lower part of the push plate is provided with an inclined surface.

[0010] In a preferred embodiment of this invention, the pusher plate is located below the storage hopper.

[0011] As a preferred embodiment of this utility model, a filter is provided at the end of the water pipe on the left side, a filter screen is embedded in the filter, and a number of filter cottons are arranged at equal intervals inside the filter.

[0012] As a preferred embodiment of this utility model, a glass plate is embedded on one side of the filter.

[0013] As a preferred embodiment of this utility model, a fixing plate is fixedly connected to one side of the water collection tank, and a detector is placed on the fixing plate. The detector is connected to the filter via a connecting line.

[0014] As a preferred embodiment of this utility model, a fixing frame for fixing the filter is fixedly connected to the inner side of the water collection tank.

[0015] As a preferred embodiment of this utility model, the first motor is covered with a waterproof cover.

[0016] Compared with the prior art, the present invention has the following technical effects: 1. By starting the second motor, the second motor drives the scraper to rotate, so that the scraper scrapes out the impurities attached to the bottom of the water collection tank while pushing out the impurities, ensuring that the impurities are completely discharged.

[0017] 2. The push plate is pushed to the left and rear by the pressure plate, so that the push plate no longer blocks the discharge port of the storage hopper, and the flocculant in the storage hopper enters the water collection tank, thereby realizing automatic feeding.

[0018] 3. When the separated sewage is pumped out through the water pipe by the water pump on the left, the separated sewage is first filtered through the filter screen, and then enters the filter for secondary filtration by the filter cotton. In this way, the remaining impurities in the sewage are removed, thereby improving the sewage treatment effect. Attached Figure Description

Detailed Implementation

[0025] 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. Example 1

[0026] Please see Figure 1 and Figure 2A solid-liquid separation type sewage treatment tank includes a collection tank 1. Two symmetrically distributed slide rails 2 are welded to the lower front side of the collection tank 1. A baffle 201 is slidably mounted on both slide rails 2. A guide plate 3 is connected and communicates with the front side of the collection tank 1 to facilitate the discharge of impurities. Mounting plates 11 are provided on both the left and right sides of the collection tank 1. A water pump 12 is mounted on the mounting plate 11, and a water pipe 13 is mounted on the water pump 12. A support frame 4 is welded to the upper part of the collection tank 1. A first motor 5 is mounted in the middle of the support frame 4, and the first motor 5 is covered with a waterproof cover 26. A waterproof cover 26 is used to protect the first motor 5. A stirrer 6 for stirring sewage is provided on the output shaft of the first motor 5. The operation of the first motor 5 can cause the stirrer 6 to rotate and stir the sewage. A pressure plate 9 is slidably provided at the lower part of the stirrer 6. A first elastic element 10 for resetting the pressure plate 9 is sleeved on the pressure plate 9. The two ends of the first elastic element 10 are respectively connected to the pressure plate 9 and the stirrer 6. A second motor 7 is installed at the lower middle position of the water collection tank 1. A scraper 8 is provided on the output shaft of the second motor 7. The operation of the second motor 7 can cause the scraper 8 to rotate and scrape off the impurities attached to the water collection tank 1.

[0027] In use, the wastewater is pumped into the collection tank 1 by starting the water pump 12 on the right. Then, the first motor 5 is started and flocculant is added to the collection tank 1 to flocculate the impurities in the wastewater. At the same time, the first motor 5 drives the agitator 6 to rotate, which stirs the wastewater to ensure that the wastewater and flocculant are fully mixed, thereby improving the flocculation effect. After stirring to a certain extent, the first motor 5 is turned off and the tank is left to stand, allowing the impurities to settle to the bottom of the collection tank 1 and separate from the wastewater. After the impurities are separated from the wastewater, the water pump 12 on the left is started, and the water pump 12 on the left pumps out the separated wastewater through the water pipe 13. After the wastewater is extracted, the baffle 201 is pulled to the left to discharge the settled impurities, and the second motor 7 is started. The second motor 7 drives the scraper 8 to rotate, so that the scraper 8 scrapes out the impurities attached to the bottom of the collection tank 1 while pushing out the impurities, ensuring that the impurities are completely discharged. Example 2

[0028] Based on Example 1, please refer to Figure 3The upper rear side of the water collection tank 1 is fixedly connected to a limiting frame 15 by welding. The limiting frame 15 is provided with a storage hopper 14 for storing flocculant. A guide rod 16 is slidably provided on the storage hopper 14. A push plate 18 for blocking the discharge port of the storage hopper 14 is fixedly connected to the right end of the guide rod 16. The push plate 18 is located below the storage hopper 14 and has an inclined surface at its lower part. Through the inclined surface, the push plate 18 can squeeze the pressure plate 9 to move downward. A second elastic element 17 is sleeved on the guide rod 16 to reset the push plate 18. The two ends of the second elastic element 17 are respectively connected to the push plate 18 and the storage hopper 14.

[0029] When the agitator 6 rotates, the pressure plate 9 pushes the push plate 18 to move to the left and rear, and the second elastic element 17 is compressed accordingly. The push plate 18 no longer blocks the discharge port of the storage hopper 14, and the flocculant in the storage hopper 14 enters the collection tank 1, thereby realizing automatic feeding. When the push plate 18 moves and contacts the limit frame 15, the limit frame 15 stops the push plate 18, and the push plate 18 can no longer move. At this time, under the action of the inclined surface on the push plate 18, the push plate 18 squeezes the pressure plate 9 to move downward, and the first elastic element 10 is compressed accordingly. The pressure plate 9 separates from the push plate 18. Under the reset elastic force of the first elastic element 10, the pressure plate 9 resets upward, and the second elastic element 17 drives the push plate 18 to reset and block the discharge port of the storage hopper 14. The flocculant stops entering the collection tank 1. This process is repeated to realize intermittent flocculant feeding, thereby effectively controlling the amount of flocculant fed.

[0030] Please see Figure 4 A filter 19 is installed at the end of the water pipe 13 on the left side. A glass plate is embedded in the right side of the filter 19, through which the sewage filtration situation inside the filter 19 can be observed. A filter screen 20 is embedded in the bottom of the filter 19. The filter screen 20 can be removed and replaced. Three filter cottons 21 are evenly spaced inside the filter 19. The three filter cottons 21 can also be removed and replaced. The filter screen 20 and the three filter cottons 21 are used to filter sewage. A fixing frame 25 for fixing the filter 19 is fixedly connected to the left side of the water collection tank 1 by welding.

[0031] Please see Figure 5 A fixing plate 23 is fixedly connected to the left side of the water collection tank 1 by welding. A detector 24 is placed on the fixing plate 23. The detector 24 is used to detect sewage. The detector 24 is connected to the filter 19 through a connecting line 22.

[0032] When the water pump 12 on the left pumps out the separated sewage through the water pipe 13, the separated sewage is first filtered through the filter screen 20, and then enters the filter 19 for secondary filtration by the filter cotton 21. This removes the residual impurities in the sewage, thereby improving the sewage treatment effect. When the sewage filtered by the filter cotton 21 is pumped out, the detector 24 can detect the sewage to check whether the sewage meets the discharge standards.
