Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a floating sludge collecting device for a wastewater treatment pool. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people. The surface of the sewage treatment pool often has floating mud and floating objects, which has a certain impact on the daily management of sewage treatment companies. Therefore, a wastewater treatment pool floating mud slag collection device is needed.

[0003] For example, the patent with application number: 202022186318.7 discloses a sludge collecting device for a sewage treatment pool, including a pool body, a winding mechanism, a sludge lifting frame, a sealing mechanism and a collecting mechanism. A support frame is installed on the side wall of the pool body through a sliding assembly, and symmetrically arranged motors are fixedly installed on the side walls at both ends of the support frame. A rotating rod is fixedly installed on the output end of the motor, and a winding wheel is fixedly installed on the end of the rotating rod away from the motor. A lifting rope is wound in the winding groove of the winding wheel, and the end of the lifting rope away from the winding wheel is connected to the sludge lifting frame. The sealing mechanism is installed on the sludge lifting frame, and the collecting mechanism is installed on the side wall of the pool body. The lifting rope is wound up by the rotation of the two sets of motors, so that the sludge lifting frame placed inside the pool body can be lifted out of the pool body, and the sludge in the sewage is collected into the sludge lifting frame, and the sludge lifting frame is tilted to pour the sludge into the collecting frame for collection.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the scum in the sewage has a certain degree of adhesion due to the water content. The above-mentioned patent separates the scum from the water surface for collection through a scum lifting frame. The scum will adhere to the bottom wall and inner wall of the scum lifting frame. The tilting of the scum lifting frame cannot effectively pour the scum into the collection frame. There will be a large amount of residual scum in the scum lifting frame, and the scum cleaning effect is poor. Therefore, a scum edge collection device for a wastewater treatment pool is proposed.

[0025] Example 1:

[0026] See also Figure 1-4 The utility model provides a device for collecting sludge and slag at the edge of a wastewater treatment pool, including a collecting pool 1, a partition 11 is fixedly installed in the collecting pool 1, a sewage chamber 111 for storing sewage is formed between the partition 11 and the collecting pool 1, a scraper 12 is also fixed in the collecting pool 1, a reflux chamber 121 and a sludge chamber 122 are formed on both sides of the scraper 12, a guide port 112 is installed on the partition 11, the guide port 112 extends to the top of the reflux chamber 121, a roller 123 and a conveyor belt 13 are installed in the reflux chamber 121, the roller 123 is used to drive the conveyor belt 13 to rotate, the conveyor belt 13 is located below the guide port 112, the conveyor belt 13 is used to transport the sludge to the sludge chamber 122, the conveyor belt The belt 13 is in contact with the scraper 12, and a driving motor 14 is installed outside the collection tank 1 to drive the roller 123 to rotate, thereby driving the conveyor mesh belt 13 to rotate. The scum in the collection tank 1 flows through the diversion port 112 through the water flow to the upper end of the conveyor mesh belt 13. The conveyor mesh belt 13 rotates to transport the scum to the scum chamber 122, and scrapes the surface of the conveyor mesh belt 13 by the scraper 12 to prevent the scum from sticking to the conveyor mesh belt 13. A return water device for transporting the water in the return chamber 121 into the collection tank 1 is also installed in the reflux chamber 121. The water in the reflux chamber 121 is returned to the collection tank 1 through the return water device, ensuring the water level height of the collection tank 1 and driving the water surface flow in the collection tank 1, so that the scum is transported to the diversion port 112 through the water flow.

[0027] Please pay attention to Figure 3 The return water device includes a water pump 15 fixedly installed on the outside of the collection tank 1. The water inlet of the water pump 15 is connected to the water inlet pipe 151, and the water inlet pipe 151 is communicated with the reflux chamber 121. The water outlet of the water pump 15 is connected to the water delivery pipe 152, and the water delivery pipe 152 is communicated with the collection tank 1. The water in the reflux chamber 121 is transported into the collection tank 1 through the water inlet pipe 151 and the water delivery pipe 152 by the water pump 15 to ensure the water level of the collection tank 1. The water reflux design reduces the consumption of water resources and improves environmental protection.

[0028] Please pay attention to Figure 3The height of the water pipe 152 is higher than the height of the water surface of the sewage chamber 111. Through this design, the water delivered by the water pipe 152 is impacted on the water surface of the sewage chamber 111, thereby strengthening the water surface flow of the sewage chamber 111, facilitating the scum to flow better to the diversion port 112. The height of the diversion port 112 is lower than the water surface height of the collection tank 1. Through this design, the scum in the collection tank 1 can flow better to the diversion port 112.

[0029] Please pay attention to Figure 3 The bottom wall of the reflux chamber 121 is provided with a slope inclined toward the water inlet pipe 151, so that the water in the reflux chamber 121 can flow toward the water inlet pipe 151 better, facilitating reflux.

[0030] Please pay attention to Figure 2-3 A filter screen 124 for filtering scum is also fixedly installed in the reflux chamber 121. The filter screen 124 is located below the conveyor belt 13. Through this design, the sewage used for reflux in the reflux chamber 121 is filtered to prevent the residual scum from being transported into the water pump 15 through the reflux chamber 121 and causing damage to the water pump 15.

[0031] Please pay attention to Figure 3-4 There are two rollers 123 for driving the conveyor mesh belt 13 to rotate. The two rollers 123 are set at different heights. Gears are fixed at both ends of the rollers 123. Toothed belts are fixed at both ends of the conveyor mesh belt 13. The toothed belts are engaged with the gears. The gears are driven to rotate by the rollers 123, thereby driving the toothed belts and the conveyor mesh belt 13 to rotate to transport the scum. The design of the high and low setting of the rollers 123 makes the conveyor mesh belt 13 inclined, so that the conveyor mesh belt 13 can better transport the scum into the scum chamber 122.

[0032] Please pay attention to Figure 3 The end of the scraper 12 is tapered, and the tip of the scraper 12 contacts the surface of the conveyor belt 13, so that the scraper 12 can better scrape off the scum on the conveyor belt 13 to avoid scum adhesion. At the same time, the tapered design prevents scum from accumulating at the end of the scraper 12.

[0033] The working principle of the first embodiment of the present invention is as follows:

[0034] During use, the water level of the sewage with scum in the collection tank 1 is between the water pipe 152 and the diversion port 112. Since the water level is higher than the diversion port 112, the sewage in the collection tank 1 drives the scum to flow to the diversion port 112 and flows onto the top of the conveyor mesh belt 13. The scum falls on the conveyor mesh belt 13, and the drive motor 14 is started. The output shaft of the drive motor 14 rotates to drive the roller 123 to rotate. The roller 123 drives the toothed belt and the conveyor mesh belt 13 to rotate through the gear, so that the conveyor mesh belt 13 transports the scum on the surface to the scum chamber 122, and the scraper 12 scrapes the surface of the conveyor mesh belt 13 to scrape off the scum adhering to the conveyor mesh belt 13. The scraped scum falls into the scum chamber 122. 112 , and the scum is filtered through the filter screen 124 . The filtered sewage is transported to the water inlet pipe 151 through the reflux chamber 121 . The water pump 15 transports the sewage in the reflux chamber 121 through the water inlet pipe 151 and the water pipe 152 to the top of the collection tank 1 . The reflux flows into the water of the collection tank 1 , ensuring that the water level in the collection tank 1 is always higher than the height of the diversion port 112 , thereby ensuring that the water surface in the collection tank 1 always drives the scum to flow to the diversion port 112 , realizing the water circulation flow to drive the scum to be transported and collected, and having a good cleaning effect on the scum.

[0035] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
