Description

Technical Field

[0001] The invention relates to the technical field of decanters, in particular to an improved CASS tank decanter automatic slag collecting device. Background Art

[0002] The decanter is mainly used to extract the supernatant during sewage treatment. The main technical means is to continuously adjust the notch height of the decanter so that the notch of the decanter is always at the water surface and the water on the surface flows into the notch. In the prior art, in order to prevent scum from entering the notch of the decanter, a baffle is generally set in front of the notch to prevent scum from entering the notch along the water flow.

[0003] However, since the water filtering speed of the decanter is fast, the water flow speed is also fast. The scum blocked by the baffle can be carried into the decanter in the fast-flowing water flow, which not only reduces the water quality, but also may cause the decanter to be blocked for a long time, affecting the water filtering speed. In addition, the scum is not processed and always stays in the sewage pool and floats on the water surface. The decanter needs to work near the water surface. Therefore, the long-term accumulation will further affect the water filtering work of the decanter. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 6 The present invention provides a technical solution: an improved CASS pool decanter automatic slag collection device, comprising a decanter 01 and a driving mechanism capable of driving the decanter 01 to rotate to perform a decanting function.

[0030] The upper end of the decanter 01 is connected with a notch 02, and a water inlet 23 for water inlet is provided at the front end of the notch 02. A drain port 17 for supplying water to the decanter 01 is provided at the position where the notch 02 and the decanter 01 are connected. There are multiple drain ports 17 on the notch 02, and the direction of the drain ports 17 is perpendicular to the axis of the notch 02.

[0031] It also includes a separation mechanism capable of filtering the scum, the separation mechanism includes a filter cartridge 03 rotatably connected to the slot 02, the filter cartridge 03 and the inner wall of the slot 02 are gap-matched, and also includes a conveying drive mechanism capable of driving the filter cartridge 03 to rotate;

[0032] The separation mechanism also includes a shovel mechanism for concentrating the scum collected by the separation mechanism.

[0033] When decanting, as in the prior art, the lower end of the decanter 01 is fixedly installed and used as a hinge point, and the upper end is rotated to adjust the height of the notch 02. By adjusting the height of the notch 02, the notch 02 is brought close to the water surface. When the water inlet 23 is lower than the water surface, water can enter the notch 02 through the water inlet 23, and then flow into the decanter 01 through the drain port 17, and then be sent to the next process for treatment through the decanter 01.

[0034] Different from the prior art, in the present technology, a filter cartridge 03 is rotatably connected in the slot 02, and the filter cartridge 03 can filter the scum floating on the water surface, reduce the scum entering the slot 02, realize the separation of the supernatant and the scum, and improve the working effect of the decanter. In addition, it can also filter the impurities in the water and improve the water quality; moreover, the filter cartridge 03 can be driven to rotate by the conveying drive mechanism, such as Figure 1 As shown, the direction of rotation is counterclockwise ( Figure 2The filter element 03 is a filter element which is filtered by the filter element 03 and then filtered by the filter element 03.

[0035] As a further solution of the present invention, the shovel mechanism includes a collecting platform 05 fixedly connected to the slot 02, the collecting platform 05 is located above the filter cartridge 03, the end of the collecting platform 05 close to the filter cartridge 03 is pointed and tightly attached to the filter cartridge 03, and the end away from the filter cartridge 03 is tilted downward.

[0036] When the scum is filtered and separated by the filter cartridge 03 and rotated upward to the position of the collecting platform 05, since the collecting platform 05 is closely attached to the outer wall of the filter cartridge 03, the outer wall of the collecting platform 05 can be scraped, so that the scum on the surface of the filter cartridge 03 is shoveled onto the collecting platform 05, and since the collecting platform 05 is inclined, after the scum falls onto the collecting platform 05, it will be concentrated on the inclined side of the collecting platform 05, and the scum filtered out by the filter cartridge 03 can be collected by the collecting platform 05, and the surface of the filter cartridge 03 can be scraped at the same time, thereby reducing the scum blocking the filter cartridge 03, improving the filtering efficiency of the filter cartridge 03, and ensuring the water permeability of the filter cartridge 03, thereby ensuring that the decanter 01 can efficiently inlet water.

[0037] As a further solution of the present invention, the separation mechanism includes a slag lifting mechanism, which includes a plurality of lifting plates 04 arranged on the filter cartridge 03 in a circular array with the axis of the filter cartridge 03 as the center.

[0038] When the filter cylinder 03 rotates, the lifting plate 04 will also be driven to rotate. Since the scum may exist in large pieces or gather together, and the filter cylinder 03 is round, larger scum is not easy to adhere to the outer wall of the filter cylinder 03. Therefore, in order to improve the collection efficiency of the scum, by setting the lifting plate 04, the lifting effect of the scum can be increased, which promotes the removal speed of the scum, thereby ensuring the water inlet efficiency at the water inlet 23 position.

[0039] As a further solution of the present invention, the lifting plate 04 is slidably connected to the filter cartridge 03 with the movement direction perpendicular to the axial direction of the filter cartridge 03. An inner groove 22 is provided on both sides of the sliding connection between the filter cartridge 03 and the lifting plate 04. A slider 19 is slidably connected in the inner groove 22. A spring 21 is provided in the inner groove 22 for returning the slider 19 to the inner direction of the inner groove 22. A non-retractable cable 20 is fixedly connected between the slider 19 and the lifting plate 04. A limit ring 14 for limiting the sliding position of the limit slider 19 is fixedly connected in the inner groove 22. Bevel openings 11 are provided at both ends of the lifting plate 04.

[0040] Since the collecting platform 05 needs to scrape and clean the outer wall of the filter cartridge 03 to ensure the water permeability of the filter cartridge 03, the collecting platform 05 needs to always be close to the outer wall of the filter cartridge 03, and the lifting plate 04 will hinder the rotation of the filter cartridge 03. At this time, when the lifting plate 04 rotates to the position of the collecting platform 05, since the lifting plate 04 is provided with an inclined opening 11, and the end of the collecting platform 05 close to the lifting plate 04 is provided with an inclined surface (such as Figure 4 ), so the beveled surface of the collecting platform 05 pushes the beveled opening 11 of the lifting plate 04 to make the lifting plate 04 retract toward the filter cartridge 03, until it moves into the position in the slot 02 as the filter cartridge 03 rotates, and the inner wall of the slot 02 will resist the lifting plate 04, so that it cannot extend out of the filter cartridge 03. When the lifting plate 04 retracts, the movement of the lifting plate 04 will pull the slider 19 to slide in the inner groove 22 through the cable 20, until the slider 19 is limited by the limiting ring 14, the spring 21 is stretched, and the cable 20 can prevent the lifting plate 04 from completely slipping off.

[0041] As a further solution of the present invention, a conveying cylinder 07 is fixedly connected to the slot 02, and the conveying cylinder 07 extends into the filter cylinder 03. One end of the conveying cylinder 07 located in the filter cylinder 03 is rotatably connected to the filter cylinder 03. A material receiving plate 13 is fixedly connected to the left side of the conveying cylinder 07, and a scraper 12 is fixedly connected to the right side of the conveying cylinder 07. An opening 08 is provided on the slot 02 near the scraper 12, and a slope 18 is provided on the slot 02 below the opening 08. A water inlet 23 is fixedly connected to the scraper 12.

[0042] There may also be a situation where floating scum enters the filter cartridge 03. In this case, the floating scum in the filter cartridge 03 needs to be processed. As the filter cartridge 03 rotates clockwise, Figure 4When the filter cartridge 03 is cleaned by the collecting platform 05, the lifting plate 04 is retracted into the filter cartridge 03 until it moves to the opening 08. At this time, the spring 21 will reset and drive the lifting plate 04 to reset and extend out of the filter cartridge 03. At this time, the scraper 12 can be closely attached to the inner wall of the filter cartridge 03 for scraping and cleaning. The lifting plate 04 will not form an obstacle. As the filter cartridge 03 continues to rotate, when the lifting plate 04 located in the opening 08 moves to the position of the slope 18, the slope 18 will push the lifting plate 04 to continue to retract into the filter cartridge 03. As the filter cylinder 03 rotates, the lifting plate 04 is always retracted into the filter cylinder 03. Therefore, when the lifting plate 04 passes the lowest point in the filter cylinder 03, the scum at the bottom of the lifting plate 04 can always be salvaged, and driven to the side of the receiving plate 13 as the filter cylinder 03 rotates. At this time, the lifting plate 04 rotates to an inclined angle. Under the action of gravity, the scum will fall from the lifting plate 04 to the receiving plate 13, and then enter the conveying cylinder 07 through the feed port 16. The scum scraped off by the scraper 12 will enter the conveying cylinder 07 through the feed port 15.

[0043] As a further solution of the present invention, the conveying drive mechanism includes an auger 09 arranged in the conveying cylinder 07 for conveying materials. The auger 09 is fixedly connected to the filter cylinder 03. The conveying cylinder 07 is provided with a feed port 15 and a feed port 16 for feeding the materials on the receiving plate 13 and the scraper 12 into the conveying cylinder 07. The slot 02 is provided with a sealed motor that can drive the auger 09.

[0044] As a further solution of the present invention, a conveying cylinder 06 is fixedly connected to the slot 02, the conveying cylinder 06 is fixedly connected and communicated with the collecting platform 05, an auger 2 10 is arranged in the conveying cylinder 06, the auger 2 10 is transmission-connected with the auger 1 09, and the conveying cylinder 06 is communicated with the conveying cylinder 2 07.

[0045] The motor drives the auger 09 to rotate. When the auger 09 rotates, the scum in the conveying barrel 07 can be sent out of the slot 02. At the same time, since the auger 09 is fixedly connected to the filter barrel 03, the filter barrel 03 will also be driven to rotate when the auger 09 rotates. In addition, the auger 09 is also connected to the auger 10 by transmission (such as a belt), so the auger 09 will also drive the auger 10 to rotate at the same time. Therefore, one motor can drive the entire device to work at the same time, which reduces the cost of use. The conveying barrel 06 and the conveying barrel 07 are connected, so that the scum in the conveying barrel 06 can be transported into the conveying barrel 07 through the auger 10 for centralized processing.
