Description

Technical Field

[0001] The utility model belongs to the technical field of mud scrapers, and in particular relates to a half-bridge peripheral mud scraper. Background Art

[0002] The semi-bridge peripheral scraper is a kind of equipment used for sewage treatment and solid-liquid separation. Its main function is to recover suspended solids in the clarifier and improve water quality. It combines the characteristics of mechanical scraping and flocculation of suspended solids to achieve better sludge capture and treatment effects.

[0003] Traditional scraper parts are mostly fixed scraper plates for scum and lighter suspended matter, which cannot adapt to changes in water surface and effectively remove scum and lighter suspended matter. The scraper may not be able to completely remove scum, resulting in poor water treatment effect, sludge dispersion, and increased difficulty in collection. Considering the convenience of maintenance and cleaning, the lack of scraper parts that can adapt to changes in water surface may make cleaning and maintenance between scraper parts more difficult, increasing downtime and work intensity. Utility Model Content

[0004] The present invention aims to solve the technical problem that the fixed scraper plate in the above-mentioned prior art cannot adapt to the change of water surface, which makes the cleaning and maintenance between the scraper parts more difficult and the treatment effect is reduced.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A semi-bridge peripheral scraper comprises a water reservoir, a working bridge is arranged above the guide cylinder at the center of the inner side of the water reservoir, one end of the working bridge is placed on the central rotating support at the top of the guide cylinder, and the end beam at the other end is placed on the water reservoir and connected to the driving mechanism, the bottom of the working bridge is connected to the fixed truss through a scraping arm, and a scraper plate is fixed on the fixed truss;

[0007] A scum scraper is provided on the upper part of the scraper arm, one end of the scum scraper contacts with the guide cylinder, and the other end contacts with the scum bucket. A hinged scraper plate for scraping off the sludge accumulated on the scum scraper is provided on the side of the working bridge away from the guide cylinder, and a scum bucket is provided below the hinged scraper plate.

[0008] Preferably, a sludge pool is provided inside the water reservoir, a transport pipe is fixedly installed inside the sludge pool, and the guide tube is fixed on the top of the transport pipe.

[0009] Preferably, a water outlet weir is provided on the side wall of the water reservoir, and a scum baffle is provided on the inner side of the water reservoir and inside the water outlet weir.

[0010] Preferably, the slag bucket is used to collect the scraped sludge and flush it through a flushing mechanism to remove the attachments on the hinged scraper plate.

[0011] Compared with the prior art, the technical effects and advantages of the utility model are:

[0012] The central rotating support in the half-bridge peripheral scraper is the main supporting structure of the half-bridge peripheral scraper, which allows the machine to rotate around the center point. The guide tube is used to guide the water flow so that the suspended matter is concentrated in the central area of ​​the clarifier for subsequent sludge capture. The working bridge connects the scraper and other components, and it can move on half of the clarifier to complete the scraping work. The scum scraper is located on one side of the working bridge and is used to scrape off the scum; the scraper is installed on the fixed truss to capture and gather sludge. When the working bridge moves, the scraper can be close to the bottom of the pool to scrape and collect the sludge. The hinged scraper is located on the other side of the working bridge and is used to scrape off the sludge accumulated on the scraper. The slag bucket is used to collect the scraped sludge and flush it through the flushing mechanism to remove the attachments on the scraper and scraper. The end beam is another supporting structure of the half-bridge peripheral scraper, and the drive mechanism is responsible for driving the working bridge and scraper to move. The outlet weir is used to guide the water flow so that the water in the pool can flow out; the scum baffle is used to control the direction of the scum so that it enters the scum bucket.

[0013] When the semi-bridge peripheral scraper is working, the driving mechanism drives the working bridge to move along the periphery of the clarification tank. The scraper blade is close to the bottom of the tank, scraping the sludge to the scum area in the center of the tank, and then the sludge is discharged through the scum scraper and slag discharge system, thereby achieving the purpose of cleaning and improving water quality.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The following is combined with Figure 1-2 To further explain this application in detail,

[0019] The embodiment of the present application discloses a semi-bridge peripheral scraper, comprising a water reservoir, a working bridge 3 is arranged above the guide tube 2 at the center of the inner side of the water reservoir, one end of the working bridge 3 is placed on the central rotating support 1 at the top of the guide tube 2, and the end beam 8 at the other end is placed on the water reservoir and connected to the driving mechanism, the bottom of the working bridge 3 is connected to the fixed truss 5 through the scraping arm 11, and the fixed truss 5 is fixed with a scraper plate 12;

[0020] A scum scraper 4 is provided on the upper part of the scraper arm 11, one end of the scum scraper 4 contacts the guide tube 2, and the other end contacts the scum bucket 7. A hinged scraper plate 6 for scraping off sludge accumulated on the scum scraper 4 is provided on the side of the working bridge 3 away from the guide tube 2, and a scum bucket 7 is provided below the hinged scraper plate 6 for connection.

[0021] The water reservoir is used to store water to be treated, and the suspended solids therein will be captured and separated by the scraper in the subsequent treatment process. The guide tube 2 is located at the inner center of the water reservoir, and its function is to guide the water flow so that the suspended solids are concentrated in the central area of ​​the water reservoir, which is convenient for the scraper to process. The working bridge 3 is the main scraper component, which is connected to the driving mechanism through the central rotating support 1 and the end beam 8, and can move around the water reservoir. It is connected to the fixed truss 5 through the scraper arm 11, and the fixed truss 5 is fixed with a scraper plate 12 for scraping the sludge at the bottom of the pool; the scraper arm 11 is connected to the fixed truss 5, and the scraper plate 12 is fixed to the fixed truss 5. The working bridge 3 and the fixed truss 5 are connected, and a scraper plate 12 is installed on the fixed truss 5. The scraper plate 12 is used to scrape the sludge on the bottom of the pool. The scum scraper 4 is located on the upper part of the working bridge 3, one end of which is in contact with the guide tube 2, and the other end is in contact with the slag discharge bucket 7. It is used to scrape the scum suspended on the water surface and guide it to the slag discharge bucket 7. The hinged scraper plate 6 is arranged on the side of the working bridge 3 away from the guide tube 2, and is used to scrape the sludge accumulated on the scum scraper 4 and scrape it into the slag discharge bucket 7. The slag discharge bucket 7 is used to collect the scraped sludge, and the sludge can be discharged from the equipment through the slag discharge bucket 7.

[0022] The hinged scraper plate 6 can adapt to the change of water surface and effectively remove the floating scum and lighter suspended matter.
