[0002] A sedimentation tank is a structure that uses sedimentation to remove suspended matter from water. It is a device for purifying water. It uses the natural sedimentation or coagulation sedimentation of water to remove suspended matter from water.

[0003] In the process of sewage treatment, it is usually necessary to go through multiple sedimentation. The substances that need to be removed from the sewage at different stages of sedimentation are usually different. In the process of initial sedimentation, grease and scum in the sewage usually float on the surface of the sewage. If this part of the grease and scum is not cleaned in time, it will cover the sewage, which will affect the technicians' observation of the progress of sewage treatment. When the sewage contains too much grease and scum, it is usually not easy to completely clean the excessive grease and scum in some existing sedimentation tanks. Therefore, a structure is set to solve the problem that some existing sedimentation tanks have poor effects in cleaning grease and scum.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] The froth removal type sedimentation tank, such as Figure 1 , Figure 2 and Figure 4 As shown, it includes a pool body 1 with an opening at the top, and the pool body 1 is used to achieve stable support and limiting effects on various parts. Partitions are symmetrically arranged in the pool body 1, and the partitions divide the interior of the pool body 1 into a liquid storage chamber 2 and a foam storage chamber 3 symmetrically arranged relative to the liquid storage chamber 2. The partitioning effect of the partition ensures that the liquid storage chamber 2 and the foam storage chamber 3 can be stably formed on the inner side of the pool body 1. The liquid storage chamber 2 is used to store and stand still sewage, so that solid settled impurities can be settled, and impurities such as floating foam will float on the surface of the sewage. The pool body 1 is transmission-connected with a foam scraper part that can slide back and forth along its length direction. The foam scraper part is symmetrically provided with a foam pushing surface 4 that contacts the floating foam, and the foam pushing surface 4 can slide from above the foam storage chamber 3 to above the foam storage chamber 3. This arrangement ensures that the foam scraper part can stably scrape the floating foam on the surface of the sewage from the liquid storage chamber 2 to the foam storage chamber 3.

[0027] like Figure 2 and Figure 3As shown, the partition includes a fixed plate 5 fixedly connected to the inner bottom surface of the pool body 1 and a sliding plate 6 located above the fixed plate 5 and slidably connected to the pool body 1. A feeding port 7 is arranged between the sliding plate 6 and the fixed plate 5. The opening degree of the feeding port 7 is inversely proportional to the distance from the foam pushing surface 4 to the center line of the foam storage chamber 3. The greater the extent to which the foam pushing surface 4 enters the top of the foam storage groove, the greater the extent to which the sliding plate 6 deviates from the fixed plate 5, thereby making the feeding port 7 open more fully, and the floating foam scraped by the foam pushing surface 4 will be stably pushed into the foam storage chamber 3.

[0028] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, a symmetrically arranged sliding groove 8 is opened on the cavity wall of the foam storage cavity 3, and a sliding block 9 sliding in the sliding groove 8 is fixedly connected to the sliding plate 6 by welding. The sliding of the sliding block 9 in the sliding groove 8 can realize a stable sliding connection between the sliding plate 6 and the pool body 1, and an elastic member 10 fixedly connected to the groove wall of the sliding groove 8 is fixedly connected to the sliding block 9 on the side away from the liquid storage cavity 2. The elastic member 10 is configured as a spring. When the foam pushing surface 4 enters the top of the foam storage cavity 3, it will push the sliding plate 6 to slide to the top of the foam storage cavity 3. In this process, the elastic member 10 will be squeezed and deformed. When the foam scraping part cancels the thrust applied to the sliding plate 6, the elastic force generated by the elastically deformed elastic member 10 will push the sliding block 9 and the sliding plate 6 to reset.

[0029] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, a guide hole 11 is opened on the groove wall of the sliding groove 8 on the side facing the sliding block 9, and a guide rod 12 sliding in the guide hole 11 is fixedly connected to the sliding block 9 by welding. The distance from the guide hole 11 to the sliding block 9 is less than the original length of the elastic member 10. This setting ensures that the elastic member 10 is in a stable extrusion deformation state, thereby ensuring that the elastic member 10 can stably apply thrust to the sliding block 9. The sliding of the guide rod 12 in the guide hole 11 can achieve stable guiding and limiting effects on the sliding process of the sliding block 9 and the sliding plate 6, ensuring that the sliding process of the sliding plate 6 is more stable and smooth.

[0030] like Figure 1-Figure 3 As shown, the distance from the liquid level of the sewage in the liquid storage chamber 2 to the top surface of the fixed plate 5 is 0-5 cm. This arrangement ensures that the foam scraping part can stably scrape the floating foam into the foam storage chamber 3, while reducing the amount of sewage in the liquid storage chamber 2 directly flowing into the foam storage chamber 3. A foam outlet groove 13 is provided on the cavity wall of the foam storage chamber 3 near the bottom, and the floating foam in the foam storage chamber 3 can be stably discharged from the foam storage chamber 3 with the help of the foam outlet groove.

[0031] like Figure 2 and Figure 3 As shown, the bottom end of the sliding plate 6 and the top end of the fixed plate 5 fit each other and form a sealing seam 14. The cross-sectional shape along the width direction of the sealing seam 14 is set to a Z shape. This setting can extend the distance that the sewage in the liquid storage chamber 2 flows through the sealing seam 14 to the foam storage chamber 3, thereby ensuring that the sealing seam 14 can stably block and seal the sewage when the feed port 7 is closed. The fixed plate 5 and the sliding plate 6 on both sides of the sealing seam 14 are fixedly connected with elastic deformation layers 15. The elastic deformation layers 15 are set to rubber material. Under the action of the elastic force generated by the elastic member 10 of elastic deformation, the sliding plate 6 will be pushed against the fixed plate 5, and then the two elastic deformation layers 15 will be squeezed for elastic deformation. The elastic elastic force of the elastic deformation layer 15 of elastic deformation can make the elastic deformation layer 15 more tightly pressed together, thereby ensuring that the sealing degree of the sealing seam 14 is more sufficient.

[0032] like Figure 1 , Figure 5 and Figure 6 As shown, the scraping part includes a symmetrically arranged guide rail 16 with the same length as the pool body 1, the guide rail 16 is fixed to the pool body 1 by bolt locking, and the cross-sectional shape along the width direction of the guide rail 16 is set to an I-shaped, and the two guide rails 16 are slidably connected with a support frame 17, and the support frame 17 is fixedly connected with a symmetrically arranged C-shaped block, and the opening of the C-shaped block is fixedly connected with a symmetrically arranged sliding bar, and the side wall of the guide rail 16 is formed with a long groove for the sliding bar to penetrate and slide, and a stable sliding connection between the support member and the guide rail 16 is achieved through the joint action of the sliding bar and the long groove, and a driving motor 18 is fixedly connected to the support frame 17 by bolt locking, and a driving wheel 19 symmetrically arranged and abutting against the guide rail 16 is fixedly connected to the output shaft of the driving motor 18, A rotating rod that passes through the C-shaped block and is rotatably connected to the C-shaped block is fixedly connected to the output shaft of the driving motor 18. A driving wheel 19 is fixedly connected to the rotating rod and the ground and the guide rail 16 are abutted. The rotation of the driving motor 18 will drive the rotating rod to rotate, and the rotation of the rotating rod drives the driving wheel 19 to rotate. The friction between the driving wheel 19 and the guide rail 16 is used to stably drive the support frame 17 to slide back and forth on the guide rail 16. The bottom of the support frame 17 is fixedly connected to a rigid scraper plate 20 by welding. The bottom of the rigid scraper plate 20 is flush with the top surface of the elastic deformation layer 15 on the top of the fixed plate 5. This arrangement ensures that the rigid scraper plate 20 can pass over the fixed plate 5 and enter the top of the foam storage chamber 3, ensuring that the rigid scraper plate 20 can stably send impurities such as floating foam from above the sewage to the foam storage chamber 3.

[0033] like Figure 2-Figure 4As shown, a symmetrically arranged pushing rod 21 is fixedly connected to the foam pushing surface 4 by welding. With the help of the arranged pushing rod 21, the foam pushing surface 4 can be in contact with the sliding plate 6 through the pushing rod 21 before entering the foam storage chamber 3, so that the sliding plate 6 slides away from the fixed plate 5 and opens the feeding port 7, thereby ensuring that the floating foam scraped by the foam pushing plate can better enter the foam storage chamber 3 through the feeding port 7. The bottom of the rigid foam scraping plate 20 is fixedly connected to an elastic foam scraping plate 22 by bolt locking. The length of the elastic foam scraping plate 22 is consistent with the length of the rigid foam scraping plate 20 and is consistent with the width of the inner side of the pool body 1. The plate 22 is set to be made of EPDM rubber material, and the elasticity, wear resistance and good weather resistance of this type of material are used to ensure that the elastic scraper plate 22 has good and stable weather resistance and service life. At the same time, with the help of the elastic scraper plate 22, the scraper part can be fully extended into the sewage, so that the scraping effect of the scraper part is more sufficient. When the elastic scraper plate 22 contacts the fixed plate 5, the elastic scraper plate 22 will be squeezed to elastically deform. With the help of the elastic force generated by the elastically deformed elastic scraper plate 22, the elastic scraper plate 22 can be better pressed against the fixed plate 5, so that the scraper part can better scrape the floating foam on the surface of the sewage into the foam storage chamber 3.
