Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a fully automatic slag cleaning air flotation machine based on the flotation principle. Background Art

[0002] With the rapid development of industrialization and urbanization, water pollution is becoming increasingly serious, and sewage treatment has become an important task for environmental protection. In the sewage treatment process, flotation technology, as a commonly used separation method, is widely used to remove pollutants such as suspended matter and grease in sewage.

[0003] However, existing sewage treatment flotation machines have some shortcomings. First, in terms of scum collection, existing flotation machines often find it difficult to quickly and efficiently collect surface scum, resulting in low scum treatment efficiency and affecting the progress of the entire sewage treatment process. Secondly, the separation effect of scum and liquid is not ideal, and some liquid may be discharged along with the scum, which not only causes a waste of water resources, but also may increase the difficulty and cost of subsequent treatment. In addition, the existing flotation machines are not very effective in removing scum attached to the inner wall of the equipment, and scum residue is prone to occur, affecting the normal operation and treatment effect of the equipment. Finally, in terms of water resource utilization, the existing flotation machines do not fully recycle the filtrate generated during the treatment process, resulting in a low utilization rate of water resources, which does not meet the requirements of sustainable development.

[0004] In summary, the existing sewage treatment flotation machines have many problems in scum collection, separation, removal and water resource utilization. A more advanced and efficient flotation machine is needed to meet the needs of sewage treatment. Summary of the invention

[0005] In order to overcome the defects of the prior art, the object of the present invention is to provide a fully automatic slag cleaning air flotation machine based on the flotation principle.

[0006] To achieve the above-mentioned purpose, the technical scheme of the present invention is implemented as follows: a fully automatic slag cleaning air flotation machine based on the flotation principle, comprising a cleaning pool, a separation ring is installed inside the cleaning pool to separate the inside of the cleaning pool into a circular cylindrical sewage treatment chamber, a slag collecting and separating component that can slide up and down is installed inside the separation ring, a top platform is arranged directly above the cleaning pool, a stepping cylinder is installed at the center of the top platform to drive the slag collecting and separating component to slide up and down so that the slag and liquid on the surface of the sewage treatment chamber are gathered at the upper port of the separation ring and guided to the inside of the slag collecting and separating component, and two annular bubble outlet pipes are installed at the bottom of the sewage treatment chamber;

[0007] The scum collection and separation component specifically includes the following structures:

[0008] A scum collecting filtrate bucket slidably engaged in the separation ring;

[0009] A scum outlet pipe installed at the center of the bottom end of the scum collecting filtrate bucket;

[0010] A cross mounting frame installed at the upper port position of the scum collecting filtrate bucket;

[0011] The scum scraping and exporting mechanism is installed at the bottom of the cross mounting frame.

[0012] Preferably, the scum scraping and exporting mechanism specifically comprises the following structure:

[0013] A reduction motor installed at the center of the bottom of the cross mounting frame and distributed inside the floating liquid collecting bucket;

[0014] Connected to the rotating shaft at the output end of the bottom of the reduction motor;

[0015] A scraper assembly installed on the left side of the front and rear of the rotating shaft;

[0016] A spiral push blade is installed at the bottom end of the rotating shaft, and the spiral push blade is distributed as a whole inside the scum discharge pipe. A scum discharge pipe is installed at the bottom center of the cleaning pool. The scum discharge pipe is integrally sleeved on the outside of the scum discharge pipe, and the scum discharge pipe can slide inside the scum discharge pipe.

[0017] Preferably, the scraping component specifically includes the following structure:

[0018] A side connecting rod installed on the side of the rotating shaft;

[0019] The side scraper is butt-jointed to the far end of the side connecting rod, and the outer end surface of the side scraper is closely fitted to the inner wall of the floating liquid collecting bucket.

[0020] Preferably, a recovery component is installed on the outside of the cleaning tank to redirect the liquid filtered out from the bottom of the separation ring back to the sewage treatment chamber.

[0021] Preferably, the recycling component specifically includes the following structure:

[0022] A circulating liquid pump installed on the right side of the cleaning tank;

[0023] A liquid extraction conduit connected to the liquid extraction end of the circulating liquid pump, wherein the liquid inlet end of the liquid extraction conduit leads to the bottom end of the chamber separated by the separation ring;

[0024] The discharge conduit is connected to the liquid outlet end of the circulating liquid pump, and the liquid outlet end of the discharge conduit leads to the sewage treatment chamber inside the cleaning pool.

[0025] Preferably, a plurality of filtrate holes are evenly arranged on the scum collecting filtrate bucket.

[0026] Preferably, the bottom of the cleaning tank is provided with supporting feet.

[0027] Preferably, first, the sewage to be treated is injected into the sewage treatment chamber of the cleaning tank, and the annular bubble outlet pipe is started to introduce a large number of tiny bubbles into the sewage, so that the suspended matter in the sewage adheres to the bubbles and floats up;

[0028] As the bubbles drive the suspended matter to float, the scum gradually gathers on the surface of the sewage treatment chamber;

[0029] Then, the stepping cylinder is started to drive the scum collecting and separating assembly to slide downward, so that the scum collecting and filtrate bucket is immersed in the sewage until its upper end is flush with the upper port of the separation ring;

[0030] At this time, the scum and part of the liquid on the surface of the sewage treatment chamber are gathered and enter the bucket under the action of the scum collecting filtrate bucket, and the liquid is filtered out through the filtrate holes and falls to the bottom of the separation ring;

[0031] Next, the reduction motor is started to drive the rotating shaft to rotate, so that the scraping component scrapes off the scum on the inner wall of the scum collecting filtrate bucket, and at the same time, the spiral pushing blade pushes the scraped scum through the scum outlet pipe to the scum discharge pipe for discharge;

[0032] During the sewage treatment process, the liquid filtered out from the bottom of the separation ring is redirected back into the sewage treatment chamber through the recovery component, thereby realizing the recycling of water resources.

[0033] The beneficial effects of the present invention are embodied in:

[0034] Efficient scum collection: The fully automatic scum cleaning air flotation machine uses a scum collection and separation component that can slide up and down, which is driven by a stepping cylinder to slide up and down. When the scum collection and separation component moves downward, it can quickly gather the scum and liquid on the surface of the sewage treatment chamber at the upper port of the separation ring, realizing the rapid collection of scum and improving the efficiency of scum treatment.

[0035] Optimize scum separation: The scum collecting filtrate bucket is a cone-shaped structure with a large top and a small bottom. This design facilitates the collection of scum and liquid. At the same time, the filtrate holes evenly opened on the scum collecting filtrate bucket allow the liquid to be filtered out smoothly, while the scum is trapped, effectively realizing the separation of scum and liquid and improving the effect of scum treatment.

[0036] Enhanced scum scraping effect: The reduction motor in the scum scraping and exporting mechanism drives the rotating shaft to rotate, so that the scraping assembly installed on the rotating shaft can scrape off the scum attached to the inner wall of the scum collecting filtrate bucket. The outer end surface of the side scraper of the scraping assembly fits tightly against the inner wall of the scum collecting bucket, which can effectively scrape off the scum from the inner wall and improve the scum removal efficiency.

[0037] Improve resource utilization: The recovery component installed on the outside of the cleaning pool can redirect the liquid filtered out from the bottom of the separation ring back into the sewage treatment chamber, realizing the recycling of liquid, improving the utilization of water resources, and reducing the cost of sewage treatment.

[0038] In summary, this fully automatic slag removal flotation machine based on the flotation principle, through its creative structure of sinking to quickly collect surface floating liquid and slag, achieves efficient collection, separation and removal of slag, while improving the utilization rate of water resources, with significant environmental and economic benefits. The equipment has advanced design concept, reasonable structure, and easy operation, providing an effective solution for the field of sewage treatment, which helps to promote the development and application of sewage treatment technology.
