Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an automatic scum collector for wastewater treatment ponds. Background Technology
[0002] Most businesses and factories introduce wastewater into treatment ponds for processing. The treated wastewater contains a large amount of garbage, debris, and scum, so scum collectors are needed in conjunction with the wastewater treatment process.
[0003] A document with publication number CN219174243U discloses a scum collector for a sewage treatment pond, comprising a sewage pond. A collection device is provided on the outer surface of the sewage pond. The collection device includes a support frame, a grooved rod fixedly connected to the outer surface of the support frame, a sliding rod slidably connected to the inner wall of the grooved rod, a bearing rod fixedly connected to the outer surface of the sliding rod, a bearing plate fixedly connected to the outer surface of the bearing rod, a first motor mounted on the outer surface of the bearing plate, and a cylindrical tube fixedly connected to the output end of the first motor. A rectangular plate is mounted on the outer surface of the cylindrical tube, and a rectangular groove is formed inside the rectangular plate. By using the rectangular plate, operating the first motor can cause the first motor to drive the cylindrical tube to rotate, causing the rectangular plate to perform circular motion around the cylindrical tube as the center inside the sewage pond, scraping off the scum on the surface of the sewage in the sewage pond and collecting it inside the rectangular groove.
[0004] However, after the scum inside the rectangular trough is collected, it can only be cleaned from the opening on the front side. The scum is easy to fall into the sewage tank during the cleaning process. This design makes it difficult to clean the scum inside the rectangular trough and is not convenient to use.
[0005] Therefore, it is necessary to provide an automatic scum collector for wastewater treatment ponds to solve the above-mentioned technical problems. Utility Model Content
[0006] In view of the above situation and to overcome the defects of the existing technology, this utility model provides an automatic scum collector for sewage treatment ponds that can facilitate scum discharge.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] An automatic scum collector for wastewater treatment ponds includes: a wastewater pond, a support frame installed above the wastewater pond, a collection mechanism installed in the middle of the support frame, and support mechanisms installed at both ends of the support frame. The collection mechanism is used to collect scum from the wastewater pond, while the support mechanisms are used to support the support frame and adjust its height. The collection mechanism includes a motor installed on the support frame, a rotating shaft rotatably installed at the bottom of the support frame, the rotating shaft being connected to the output shaft of the motor, and the motor driving the rotating shaft to rotate. A scum collection trough is installed on the rotating shaft, a scum inlet is opened on one side of the scum collection trough, and a scum outlet is opened on the side of the scum collection trough away from the rotating shaft. A baffle plate is installed at the scum outlet.
[0009] Preferably, a baffle is installed at an angle on one side of the scum collection tank.
[0010] Preferably, the inner width of the scum collection trough is smaller than the outer width.
[0011] Preferably, the bottom of the scum collection tank is inclined.
[0012] Preferably, there are two scum collection tanks.
[0013] Preferably, the support mechanism includes a base frame, on which a hydraulic cylinder is fixedly mounted, and the top of the hydraulic cylinder is fixedly connected to the support frame.
[0014] Preferably, a guide rod is installed at the bottom of the support frame, and the guide rod is slidably connected to the base frame.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] (1) This utility model installs a support frame above the sewage tank and a cleaning mechanism including a motor, a rotating shaft and a scum collection tank on the support frame. A scum discharge port is opened at the position of the scum collection tank near the edge of the sewage tank, which can conveniently discharge the scum in the scum collection tank and make it more convenient to use.
[0017] (2) By setting the inner width of the scum collection tank to be smaller than the outer width, this utility model enables the scum entering the scum collection tank to naturally gather near the discharge port, which is beneficial for subsequent cleaning of the scum in the tank.
[0018] (3) By setting the bottom of the scum collection tank to be inclined, this utility model can reduce the labor intensity during scum discharge and make it more convenient to use;
[0019] (4) By setting two scum collection tanks, this utility model can balance the force on the rotating shaft and improve the scum cleaning speed;

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.
[0027] Example 1:
[0028] like Figure 1-4As shown, this utility model provides an automatic scum collector for sewage treatment ponds, comprising: a sewage pond 1, a support frame 2 installed above the sewage pond 1, a collection mechanism installed in the middle of the support frame 2, and support mechanisms installed at both ends of the support frame 2. The collection mechanism is used to collect scum from the sewage pond, while the support mechanisms are used to support the support frame 2 and adjust its height. The collection mechanism includes a motor 3 mounted on the support frame 2, and a rotating shaft 4 rotatably mounted at the bottom of the support frame 2. The rotating shaft 4 is connected to the output shaft of the motor 3, and the motor 3 drives the rotating shaft 4 to rotate. A scum collection trough 5 is installed on the rotating shaft 4, and a scum inlet is opened on one side of the scum collection trough 5. Drainage holes should be designed at the tail and bottom of the scum collection trough 5. The number and size of the drainage holes can be set as needed. To facilitate the discharge of scum from the scum collection trough 5... A scum discharge port 6 is opened on the side of the scum collection tank 5 away from the rotating shaft 4 (i.e., near the edge of the sewage tank 1). A plug plate 7 is installed at the scum discharge port 6 to block the scum discharge port 6. The plug plate 7 can be pulled upward. In use, the height of the support frame 2 is adjusted by the support mechanism so that the scum collection tank 5 is partially submerged in water. Then, the motor 3 drives the rotating shaft 4 to rotate, which drives the scum collection tank 4 to rotate, so that the scum enters the scum collection tank 5. When there is a lot of scum collected in the scum collection tank 5 and it needs to be cleaned, the support frame 2 is raised to raise the scum collection tank 5 until its bottom is higher than the top of the sewage tank 1. Then, the plug plate 7 is pulled out to open the scum discharge port 6. Tools can be manually inserted into the scum collection tank 5 through the scum discharge port 6 to clean out the scum. Since the scum discharge port 6 is close to the edge of the sewage tank 1, it is relatively easy to clean.
[0029] By installing a support frame 2 above the sewage tank 1, and installing a cleaning mechanism including a motor 3, a rotating shaft 4 and a scum collection tank 5 on the support frame 2, and opening a scum discharge port 6 near the edge of the sewage tank 1 in the scum collection tank 5, the scum in the scum collection tank 5 can be easily discharged, making it more convenient to use.
[0030] Example 2:
[0031] like Figure 2 As shown, a baffle 8 is installed at an angle of 30 degrees below the scum inlet of the scum collection tank 5. During the scum collection process, the baffle 8 should be completely submerged in the water. As the scum collection tank 5 rises, the baffle 8 prevents the scum in the scum collection tank 5 from falling into the water from the scum inlet.
[0032] By installing baffles 8 on the scum collection tank 5, the possibility of scum falling from the scum collection tank 5 into the sewage tank can be reduced.
[0033] Example 3:
[0034] like Figure 3As shown, in this embodiment, the inner width of the scum collection trough 5 is smaller than the outer width, that is, the width of the scum collection trough 5 near the rotating shaft 4 is smaller than the width near the insert plate 7. This causes the scum to naturally gather towards the insert plate 7 after entering the scum collection trough 5 during the rotation of the scum. Correspondingly, the scum near the rotating shaft 4 will decrease, and a large amount of scum will approach the scum discharge port 6, which is beneficial for cleaning the scum in the scum collection trough 5.
[0035] By setting the inner width of the scum collection trough 5 to be smaller than the outer width, the scum entering the scum collection trough 5 can naturally gather towards the scum discharge port 6, which is beneficial for subsequent cleaning of the scum in the box.
[0036] Example 4:
[0037] like Figure 4 As shown in the figure, in this embodiment, the bottom of the scum collection tank 5 is inclined. The inclination angle can be designed as needed. The figure is only for illustration and does not represent its actual angle. That is, the side of its bottom near the rotating shaft 4 is higher than the side near the scum discharge port 6 (insertion plate 7). After the scum collection tank 5 is raised, when the scum is taken out of the box, the inclined bottom design of the scum collection tank 5 makes the scum naturally tend to move outward (towards the outside of the sewage tank 1), which can reduce the amount of force required to remove the scum, thereby reducing labor intensity and making it more convenient to use.
[0038] By setting the bottom of the scum collection tank 5 to be inclined, the labor intensity during scum discharge can be reduced, making it more convenient to use.
[0039] Example 5:
[0040] like Figure 1 As shown, in order to balance the force on the rotating shaft 4, there are two scum collection tanks 5. The two scum collection tanks 5 are arranged in a ring array with the rotating shaft 4 as the center. This structural design can balance the force on the rotating shaft 4 and improve the scum removal speed in the sewage tank 1.
[0041] By setting the number of scum collection tanks 5 to two, the force on the rotating shaft 4 can be balanced and the scum cleaning speed can be improved.
[0042] Example 6:
[0043] like Figure 1 As shown, in this embodiment, the support mechanism includes a base frame 9, on which a hydraulic cylinder 10 is fixedly installed. The top of the hydraulic cylinder 10 is fixedly connected to the support frame 2. When in use, the hydraulic cylinder 10 is activated to extend its output shaft, thereby raising the support frame 2. Conversely, the support frame 2 is lowered. It is worth noting that the two hydraulic cylinders 10 should be used in conjunction.
[0044] By setting up a support mechanism including a base frame 9 and a hydraulic cylinder 10, the support frame 2 can be easily supported and raised or lowered.
[0045] Example 7:
[0046] like Figure 1 As shown, in this embodiment, in order to improve the stability of the support frame 2, a guide rod 11 is installed at the bottom of the support frame 2. The guide rod 11 passes through the base frame 9, that is, the guide rod 11 is slidably connected to the base frame 9. When in use, the guide rod 11 rises and falls synchronously when the support frame 2 is raised and lowered, which can effectively improve the lifting stability of the support frame 2.
[0047] By installing guide rods 11 at the bottom of support frame 2, the lifting stability of support frame 2 can be improved.
[0048] Working principle: During use, the height of the support frame 2 is adjusted by the support mechanism so that the scum collection tank 5 is partially submerged in the water. Then, the motor 3 drives the rotating shaft 4 to rotate, which in turn drives the scum collection tank 4 to rotate, causing the scum to enter the scum collection tank 5. When a large amount of scum has been collected in the scum collection tank 5 and cleaning is required, the support frame 2 is raised, raising the scum collection tank 5 until its bottom exceeds the top height of the sewage tank 1. Then, the insert plate 7 is pulled out, opening the scum discharge port 6. Tools can then be manually inserted into the scum collection tank 5 through the scum discharge port 6 to clean out the scum. Since the scum discharge port 6 is close to the edge of the sewage tank 1, cleaning is relatively convenient.
