Description

Technical Field

[0001] This utility model relates to the technical field of scum collectors, specifically an adjustable scum collector for the surface of a sedimentation tank. Background Technology

[0002] A sedimentation tank surface scum collector is used to clean impurities, grease, and scum floating on the surface of a sedimentation tank. It is usually installed at the top of the sedimentation tank and collects pollutants floating on the water surface through mechanical or air flotation methods, and then discharges or treats them to keep the tank water clean and ensure the effectiveness of sewage treatment.

[0003] In existing technologies, the scum collection efficiency is low and the collection speed is slow when collecting scum from the surface of sedimentation tanks, which can easily affect the efficiency of treatment.

[0004] To overcome the above shortcomings, Chinese patent (publication number CN101972561B) discloses an automatic scum collector for sedimentation tanks. This device solves the problem of low scum removal efficiency in existing wastewater scum treatment devices. Its body consists of an open section at the front and a closed section at the rear. The rotating shaft of the rotary brush is fixed to the front of the body via a bracket. A scraper is fixed to the front opening of the open section, with one side of the scraper tangent to the cylindrical sidewall of the rotary brush and parallel to the brush's axis. A rotary drive device is located within the closed section to drive the rotation of the rotary brush. A scum collection hopper is located within the open section, with its opening corresponding to the scraper's position. A signal receiver is located on the outer wall of the closed section. A main suspension beam is fixed at the center of gravity on the opposite sidewall of the body. The signal receiver receives signals transmitted by a signal transmitter, and its rotation signal output is connected to the rotation signal input of the rotary drive device. This device is suitable for treating scum in wastewater.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, when collecting scum on the surface of sedimentation tanks, the different water levels in different sedimentation tanks make it inconvenient to adjust the collection port, the operation of the staff is cumbersome, and the adjustment method is complicated. Utility Model Content

[0006] The purpose of this utility model is to provide an adjustable scum collector for sedimentation tanks, in order to solve the problems mentioned in the background art, such as the inconvenience of adjusting the collection port when collecting scum from the surface of sedimentation tanks due to the different water levels in different sedimentation tanks, the cumbersome operation of the operator, and the complicated adjustment methods.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable sedimentation tank surface scum collector, comprising a collection box and a conveying pipe installed inside the collection box, wherein the front end of the conveying pipe is threadedly installed at the rear end of a transfer chamber, a sewage pump is provided on the surface of the conveying pipe, and the outer side of the sewage pump is installed on the surface of the collection box; a collection port is provided at the upper end of the transfer chamber, and an adjusting collection mechanism is provided on the outer side of the collection port; a filter plate is sleeved inside the collection box, and an anti-clogging mechanism is provided on the outer side of the filter plate.

[0008] Furthermore, the regulating collection mechanism is equipped with a connecting pipe, and the upper and lower ends of the connecting pipe connect the collection port to the transfer chamber.

[0009] Furthermore, a bracket is fixedly installed on the outside of the connecting pipe, and three floats are fixedly installed on the outside of the bracket, and the floats are evenly distributed.

[0010] Furthermore, the upper end of the float box is provided with an adjustment port, and a stopcock valve is installed on the outside of the float box, and a water outlet is installed through the lower end of the collection box.

[0011] Furthermore, the anti-clogging mechanism is equipped with a drive motor, the lower end of which is fixedly installed on the outside of the collection box, and a drive rod is fixedly installed on the output end of the drive motor.

[0012] Furthermore, the outer side of the drive rod is rotatably connected to the collection box, and a cam is fixedly installed on the surface of the drive rod. The upper end of the cam is located below the filter plate, and the filter plate is slidably connected to the inner wall of the collection box.

[0013] Furthermore, a limiting plate is installed through both sides of the filter plate, and the outer side of the limiting plate is fixedly installed on the inner wall of the collection box. A partition is installed through both sides of the limiting plate, and the lower end of the partition is fixedly installed on the surface of the filter plate. A vibration spring is installed between the filter plate and the interior of the limiting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In use, add an appropriate amount of water to the float box through the adjustment port, then close the adjustment port and place the collection port and support in the sedimentation tank. This allows the water added to the float box to press down on the support and collection port, and is then drawn out by the sewage pump and delivery pipe. The drawn water enters the collection tank for collection. If it is necessary to adjust the water quality inside the float box, the water inside the float box can be discharged by activating the stopcock valve. This allows for convenient adjustment of the float box's floating height, convenient collection, and simple operation.

[0016] 2. When the scum and wastewater on the surface of the sedimentation tank are pumped out by the sewage pump, the wastewater and scum are sent to the filter plate surface inside the collection tank through the delivery pipe. The filtered wastewater is then discharged back into the sedimentation tank from the outlet at the bottom of the collection tank. No manual collection or addition is required, and the scum can be collected separately and recycled.

[0017] Furthermore, during filter plate filtration, the drive motor is activated, which in turn drives the drive rod to rotate. As the drive rod rotates, the vibration spring enhances the vibration effect, thus preventing scum from clogging the filter and allowing for continuous long-term use. Attached Figure Description

[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.

[0026] Example 1: As Figures 1-4The technical solution shown is an adjustable sedimentation tank surface scum collector. To solve the problem, it discloses: a collection box 1 and a conveying pipe 2 installed inside the collection box 1. The front end of the conveying pipe 2 is threadedly installed at the rear end of the transfer chamber 4. A sewage pump 3 is installed on the surface of the conveying pipe 2, and the outer side of the sewage pump 3 is installed on the surface of the collection box 1. A collection port 6 is provided at the upper end of the transfer chamber 4, and an adjusting collection mechanism is provided on the outer side of the collection port 6. The adjusting collection mechanism is provided with a connecting pipe 5, and the upper and lower ends of the connecting pipe 5 connect the collection port 6 to the transfer chamber 4. A bracket 7 is fixedly installed on the outer side of the connecting pipe 5, and three float boxes 8 are fixedly installed on the outer side of the bracket 7. The float boxes 8 are evenly distributed. An adjusting port 9 is provided at the upper end of the float box 8, and a stopcock valve 10 is installed on the outer side of the float box 8. An outlet 11 is installed through the lower end of the collection box 1.

[0027] In use, add an appropriate amount of water to the float box 8 through the adjustment port 9, then close the adjustment port 9 and place the collection port 6 and support 7 part into the sedimentation tank. This allows the water added to the float box 8 to press down on the support 7 and collection port 6, so that the collection port 6 is slightly lower than the level of the sedimentation tank. At this time, the water and scum on the surface of the sedimentation tank enter the transfer chamber 4 through the connecting pipe 5 at the bottom of the collection port 6. The water and scum entering the transfer chamber 4 are then extracted by the sewage pump 3 and the delivery pipe 2. The extracted water enters the collection box 1 for collection. If it is necessary to adjust the water quality inside the float box 8, the water inside the float box 8 can be discharged by activating the stopcock valve 10. This allows for convenient adjustment of the floating height of the float box 8, convenient collection, and simple operation.

[0028] Example 2: Figures 1-6 The technical solution shown, based on Embodiment 1, discloses the following to address the problem of easy clogging of collected scum: a filter plate 12 is fitted inside the collection box 1, and an anti-clogging mechanism is provided on the outer side of the filter plate 12. The anti-clogging mechanism is equipped with a drive motor 16, and the lower end of the drive motor 16 is fixedly installed on the outer side of the collection box 1. A drive rod 17 is fixedly installed on the output end of the drive motor 16. The outer side of the drive rod 17 is rotatably connected to the collection box 1, and a cam 18 is fixedly installed on the surface of the drive rod 17. The upper end of the cam 18 is located below the filter plate 12. The filter plate 12 is slidably connected to the inner wall of the collection box 1. A limiting plate 13 is installed through both sides of the filter plate 12, and the outer side of the limiting plate 13 is fixedly installed on the inner wall of the collection box 1. A partition plate 14 is installed through both sides of the limiting plate 13, and the lower end of the partition plate 14 is fixedly installed on the surface of the filter plate 12. A vibration spring 15 is installed between the filter plate 12 and the interior of the limiting plate 13.

[0029] When the sewage pump 3 removes scum and sewage from the surface of the sedimentation tank, the sewage and scum are sent to the surface of the filter plate 12 inside the collection box 1 through the conveying pipe 2. At this time, the sewage and scum are filtered by the filter plate 12. The filtered sewage is discharged back into the sedimentation tank from the outlet 11 at the bottom of the collection box 1. There is no need for manual collection and feeding. It can be recycled and the scum can be collected separately. When the filter plate 12 is filtering, the drive motor 16 is started. The start of the drive motor 16 can drive the drive rod 17 to rotate. When the drive rod 17 rotates, the cam 18 on the surface of the drive rod 17 presses the filter plate 12. The filter plate 12 is pressed upward, so that the outer side of the filter plate 12 is restricted by the limiting plate 13. At the same time, with the combination of the partition plate 14, impurities are prevented from entering the vibration spring 15. The vibration spring 15 improves the vibration effect and achieves the effect of preventing scum blockage, which can be used for a long time.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
