Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a floating skimming device for wastewater treatment. Background Technology

[0002] In the wastewater treatment process of fragrance and flavor factories, after the front-end treatment process is completed, a large amount of residue and foam often remain on the surface of the wastewater. If these impurities are not removed in time, they will not only affect the efficiency of subsequent wastewater treatment processes, but may also cause blockage or functional degradation of the treatment system. Therefore, skimming the surface of the wastewater is one of the key steps to ensure the effectiveness of wastewater treatment. Currently, most skimming equipment used in the industry relies on the mechanical movement of scraper blades to remove impurities. However, during prolonged operation, a large amount of residual impurities gradually accumulate on the surface of the scraper blades. Over time, these impurities gradually deteriorate and harden, forming a strong adhesion to the scraper blade surface. If these attached impurities are not effectively removed in a timely manner, the skimming ability of the scraper blades will significantly decrease, and impurities may even fall back into the wastewater, severely affecting the skimming effect. In traditional treatment methods, the accumulated impurities adhering to the surface of the scraper plate are usually cleaned manually. However, this method has significant limitations: firstly, the impurities on the scraper plate are difficult to remove due to their age, and manual cleaning is not only labor-intensive but also inefficient, often requiring a large amount of manpower and time; secondly, each manual cleaning process takes a long time, leading to repeated adhesion of impurities to the scraper plate, affecting efficiency. Based on this, a floating skimming device for wastewater treatment was designed, which can automatically clean the scraper plate after a period of operation, improving the automation level of the skimming device and thus ensuring the skimming effect. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a floating skimming device for sewage treatment, which can automatically clean the skimming plate after a period of operation, improve the automation level of the skimming equipment, and thus ensure the skimming effect.

[0004] The technical implementation scheme of this utility model is as follows: A floating skimming device for wastewater treatment includes a base, a housing, a first rotating shaft, a bearing seat, a skimming plate, and a skimming mechanism. The housing is located on the upper part of the base, and the upper part of the housing is provided with a bearing seat and a first rotating shaft. The upper part of the first rotating shaft is provided with a sprocket, a chain, and a skimming plate. A skimming mechanism is provided at one end of the housing.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0020] like Figures 1-5The aforementioned floating skimming device for wastewater treatment includes a base 1, a housing 2, a first rotating shaft 4, a bearing seat 3, a skimming plate 8, and a skimming mechanism 6. The housing 2 is located on the upper part of the base 1, and the bearing seat 3 and the first rotating shaft 4 are located on the upper part of the housing 2. A sprocket 5, a chain 7, and the skimming plate 8 are located on the upper part of the first rotating shaft 4. A skimming mechanism 6 is located at one end of the housing 2. The skimming mechanism 6 includes a fixed bracket 601, a screw 604, a sliding frame 603, a column 606, a lever plate 609, and a drive group. The sliding frame 603 has a sliding groove and a screw hole at its bottom that are connected to a sliding strip 602 and a screw 604 on the fixed bracket 601, respectively. A column 606 is located on the upper part of the sliding frame 603. A first fixing ear 612 is located on the column 606. A lever plate 609 is located inside the two first fixing ears 612 and is connected to the drive group.

[0021] It should be noted that a box 2 is provided on the upper part of the base 1, and two chains 7 are provided on the upper part of the box 2. The chains are driven by a third motor, and a skimming plate 8 is provided on the upper part of the two chains 7. During the transmission process, the floating matter in the sewage in the third chamber C is removed and scraped into the first chamber A, thereby realizing the sewage skimming operation.

[0022] It should be further explained that a slag scraping mechanism 6 is provided at one end of the housing 2, which can clean the slag skimmer 8 after long-term operation. The fixed bracket 601 is equipped with a slide bar 602, and the bottom of the sliding frame 603 has a groove that matches the slide bar 602. The sliding frame 603 is movably connected to the slide bar 602 on the fixed bracket 601 through the groove at its bottom, thereby achieving smooth sliding of the sliding frame 603 on the fixed bracket 601. Simultaneously, the bottom of the sliding frame 603 has a screw hole connected to a screw 604. When the screw 604 rotates, the sliding frame 603 can move under the drive of the screw 604, thereby bringing the slag scraping part closer to the upper part of the second chamber B. This prepares the surface for the slag scraping and cleaning operation. Symmetrical columns 606 are arranged on the upper part of the sliding frame 603, each column equipped with a first fixing lug 612 and a toggle plate 609. One end of the toggle plate 609 is equipped with an auxiliary wheel, which connects to a cam 613 on the second rotating shaft 608. When the second rotating shaft 608 rotates, the cam 613 rotates accordingly. Under the action of the cam 613, the toggle plate 609 will rotate, causing its slag-scraping end to contact the surface of the slag-skimming plate 8. At this time, the drive screw 604 is activated, and under the drive of the screw 604, the entire slag scraping mechanism will move to one end, thereby scraping off the deposits on the slag-skimming plate 8, thus achieving the slag scraping and cleaning operation of the slag-skimming plate 8.

[0023] like Figures 1-4As shown, the drive assembly includes a second rotating shaft 608, a third rotating shaft 607, a cam 613, and a first gear 616. The cam 613 is disposed on the second rotating shaft 608, and the side of the cam 613 is connected to the auxiliary wheel 611 at the bottom of the actuating plate 609. The first gear 616 is disposed on the side of the cam 613, and the first gear 616 meshes with the second gear 615 on the third rotating shaft 607 to form a transmission structure. The connecting shaft of the actuating plate 609 is movably connected to the first fixed ear 612, and a torsion spring is disposed at the connection between the connecting shaft and the first fixed ear 612. A scraper is disposed at one end of the actuating plate 609.

[0024] It should be noted that both the second rotating shaft 608 and the third rotating shaft 607 are located on the upper part of the column. A cam 613 and a first gear 616 are provided on the upper part of the second rotating shaft 608. The cam 613 is connected to the auxiliary wheel 611 at the bottom of the actuating plate 609. The first gear 616 is provided at one end of the cam 613 and meshes with the second gear 615 on the third rotating shaft 607, thereby driving the actuating plate on the other end to rotate and scrape off the attached substances on the skimming plate 8.

[0025] like Figures 1-5 As shown, the second rotating shaft 608 is mounted on the second fixing lug 614 of the column 606, and the second rotating shaft 608 is connected to the first drive motor via a coupling; one end of the screw 604 is connected to the output shaft of the second drive motor 605 via a coupling.

[0026] It should be noted that the second rotating shaft 608 is driven by the first drive motor, and the third rotating shaft 607 is driven simultaneously under the transmission of gears, thereby realizing the simultaneous slag scraping operation on both sides of the slag skimmer plate 8, and can operate intermittently to ensure the cleanliness of the slag skimmer plate 8.

[0027] It should be further explained that a limit switch and an infrared sensor are installed on the upper part of the housing 2, which can be used to perform cleaning operations by scraping equipment after the slag skimmer 8 reaches the cleaning position.

[0028] like Figures 1-5 As shown, the box 2 is a rectangular cavity structure with an opening at the top, and the box 2 is divided into a first chamber A, a second chamber B and a third chamber C by a partition plate. An electric heating tube is installed inside the third chamber C. A third fixing lug is provided on the other end of the column 606, and a third rotating shaft 607 is provided in the middle of the two third fixing lugs.

[0029] It should be noted that inside the tank 2, the third chamber C is used for introducing sewage for skimming operations, the second chamber B is used to collect the impurities hanging down from the skimming plate, and the first chamber A is used for collecting floating debris in the sewage.
