Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, in particular to a floating object cleaning mechanism for sewage treatment. Background Art

[0002] Sedimentation tank is a kind of structure that uses sedimentation to remove suspended matter from water and is a device for purifying water. When sewage enters the sedimentation tank, the flow rate of sewage slows down, and the suspended matter and impurities contained in the sewage begin to sink gradually. During the sinking process, the suspended matter and impurities collide and aggregate with each other, thus forming larger particles or flocs. These particles or flocs accumulate at the bottom of the sedimentation tank and form sludge. By regularly removing the sludge at the bottom of the sedimentation tank, the normal operation and purification effect of the sedimentation tank can be guaranteed.

[0003] The applicant retrieved and obtained the following prior art. Specifically, the patent with publication number CN219630687U discloses a scraper device for sewage treatment, including a driving mechanism and a mounting frame connected to the power output end of the driving mechanism, a connecting rod movably connected to the mounting frame, a ferrule arranged on the connecting rod, a mounting cavity formed on the ferrule, a scraper plate for scraping sludge and a reset member fixedly arranged to provide a reset force to the scraper plate are rotatably arranged in the mounting cavity. The utility model is a scraper device for sewage treatment. The scraper plate is rotatably installed in the cavity, so that the scraper plate can automatically deflect, thereby preventing the sludge from accumulating on both sides of the scraper plate, and plays a role in guiding and draining the sludge, so that the sludge is directly discharged to the mud outlet after passing through the scraper plate, thereby facilitating the discharge of the sludge from the mud outlet, thereby improving the cleaning efficiency. At the same time, the scraper plate is always in a state parallel to the center line of the connecting rod under the action of the reset member, thereby ensuring the scraping effect of the sludge and reliable use.

[0004] It can be seen from the above patent that although the scraper device for sewage treatment can guide and drain the sludge, improve the cleaning efficiency, ensure the scraping effect of the sludge, and is reliable to use, in actual use, due to the unstable water quality of the incoming water, if the water quality of the sewage entering the sedimentation tank fluctuates greatly, or contains a large amount of substances that are difficult to precipitate, such as grease, fiber, microorganisms, etc., these substances cannot be completely removed in the sedimentation tank and will eventually form floating objects or impurities on the surface of the sewage; at the same time, the fine suspended solids in the sewage are not completely settled, and the microorganisms (such as bacteria, microalgae, etc.) in the sedimentation tank will produce gases such as biogas during their activities or growth. These gases will adhere to the suspended matter and form floating objects or impurities on the surface of the sewage. However, the scraper device for sewage treatment can only scrape the sludge at the bottom of the sedimentation tank, but cannot clean the floating objects on the surface of the sewage. The scope of use is small, and the floating objects and impurities need to be cleaned manually later, which not only increases the labor intensity of the staff, but also reduces the cleaning efficiency. Utility Model Content

[0005] The main purpose of the utility model is to provide a floating object cleaning mechanism for sewage treatment, aiming to solve the problem that the existing scraper device cannot clean the floating objects on the sewage surface, has a small scope of use, and requires manual cleaning of the floating objects and impurities, which not only increases the labor intensity of the staff, but also reduces the cleaning efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides a floating object cleaning mechanism for sewage treatment, which is arranged on a sludge scraping device and is used to clean floating objects on the surface of sewage. The sludge scraping device includes a driving assembly, including a telescopic column, a cleaning pipe and a collecting barrel. One end of the telescopic column is detachably connected to the sludge scraping device, and the other end of the telescopic column is horizontally provided with the cleaning pipe. A through groove for floating objects to pass through is opened on the cleaning pipe along its extension direction. The cleaning pipe is connected to the collecting barrel so that the collecting barrel can collect and store floating objects, and the collecting barrel is detachably mounted on the cleaning pipe.

[0007] Preferably, a through hole is formed on the outer wall of one end of the collecting tube close to the cleaning tube, and a support tube connected to the inner cavity of the cleaning tube is formed at a position corresponding to the through hole on the telescopic column; the telescopic column is hollow so that the collecting tube can be arranged in the telescopic column, and a through hole connected to the support tube is formed on the outer wall of the collecting tube.

[0008] Preferably, a flange is formed on the outer wall of one end of the collecting tube close to the cleaning tube, and the flange is used to abut against the outer wall of the cleaning tube, and a positioning block is formed on the side of the flange opposite to the cleaning tube, and a notch for the positioning block to extend into is opened on the cleaning tube at a position corresponding to the support tube.

[0009] Preferably, end covers are detachably mounted on both ends of the collecting cylinder.

[0010] Preferably, a slope is formed on the bottom surface of the inner cavity of the cleaning tube, the slope is inclined downward toward the direction close to the support tube, and the length of the slope is greater than the length of the through groove.

[0011] Beneficial effects:

[0012] 1. When the utility model is used in practice, the floating object cleaning mechanism for sewage treatment adjusts the telescopic column up and down to the height position of the sewage surface, so that the cleaning pipe and the sewage surface are in the same horizontal plane. At this time, the telescopic column drives the cleaning pipe to rotate. Since the cleaning pipe is provided with through grooves in the left and right directions, the floating objects enter the cleaning pipe through the through grooves during the rotation of the cleaning pipe, so that the floating objects on the sewage surface can be cleaned, thereby expanding the use range of the sludge scraper device, and there is no need for the staff to manually clean and collect the sludge, which not only reduces the labor intensity of the staff, but also improves the cleaning efficiency and is reliable to use.

[0013] 2. Since the cleaning pipe is connected to the collecting barrel, and the collecting barrel is detachably mounted on the cleaning pipe, the floating objects can flow into the collecting barrel and the floating objects can be collected, so that the staff can centrally process the floating objects and the method is convenient to use.

[0026] Embodiment 1:

[0027] The utility model provides a floating object cleaning mechanism 100 for sewage treatment.

[0028] In one embodiment of the utility model, a floating object cleaning mechanism 100 for sewage treatment is provided on a scraper device 200 and is used to clean floating objects on the surface of sewage. The scraper device 200 includes a driving assembly, including a telescopic column 1, a cleaning tube 2 and a collecting barrel 3. One end of the telescopic column 1 is detachably connected to the scraper device 200, and the other end of the telescopic column 1 is horizontally provided with a cleaning tube 2. A through groove 4 for floating objects to pass through is provided on the cleaning tube 2 along its extension direction. The cleaning tube 2 is connected to the collecting barrel 3 so that the collecting barrel 3 can collect and store floating objects, and the collecting barrel 3 is detachably mounted on the cleaning tube 2.

[0029] Specifically, Figures 1 to 4 As shown, when the utility model is used, a floating object cleaning mechanism 100 for sewage treatment is installed on a scraper device 200 and driven by a driving component in the scraper device 200 to scrape and collect floating objects on the sewage surface, thereby achieving floating object cleaning on the sewage surface, and the structural design is simple and reasonable. Furthermore, by detachably connecting the lower end of the telescopic column 1 to the scraper device 200, the detachable connection method can be a threaded connection, so that the telescopic column 1 can be easily disassembled and assembled; at the same time, a cleaning pipe 2 is horizontally arranged at the upper end of the telescopic column 1, and when the driving component in the scraper device 200 drives the telescopic column 1 to rotate, the cleaning pipe 2 rotates in a horizontal plane driven by the telescopic column 1. It can be understood that when the floating object cleaning mechanism 100 for sewage treatment of the utility model is actually used, the staff adjusts the telescopic column 1 up and down to the height position of the sewage surface, so that the cleaning pipe 2 and the sewage surface are in the same horizontal plane. At this time, the telescopic column 1 drives the cleaning pipe 2 to rotate. Since the cleaning pipe 2 is provided with a through groove 4 in the left and right directions, the floating objects enter the cleaning pipe 2 through the through groove 4 during the rotation of the cleaning pipe 2, and then the floating objects on the sewage surface can be cleaned, thereby expanding the use range of the sludge scraper 200, and there is no need for the staff to manually clean and collect the sludge, which not only reduces the labor intensity of the staff, but also improves the cleaning efficiency and is reliable to use. In addition, when the floating objects enter the cleaning pipe 2, since the cleaning pipe 2 is connected to the collecting tube 3, and the collecting tube 3 is detachably mounted on the cleaning pipe 2, the floating objects can flow into the collecting tube 3 and complete the collection of the floating objects, so that it is convenient for the staff to centrally process the floating objects, which is convenient to use.

[0030] It is worth noting that the scraper device 200 and its driving assembly are both prior art, specifically a scraper device 200 for sewage treatment disclosed by the applicant in the patent publication number CN219630687U, and the utility model of a floating object cleaning mechanism 100 for sewage treatment is a technical improvement of the scraper device 200 for sewage treatment, which can solve the problem that the scraper device 200 for sewage treatment cannot clean the floating objects on the sewage surface, has a small scope of use, and requires manual cleaning of floating objects and impurities, which not only increases the labor intensity of the staff, but also reduces the cleaning efficiency. In addition, the telescopic column 1 is a mature prior art and will not be described in detail here.

[0031] In one embodiment, a through hole is formed on the outer wall of one end of the collecting tube 3 close to the cleaning tube 2, and a support tube 5 communicating with the inner cavity of the cleaning tube 2 is formed on the telescopic column 1 at a position corresponding to the through hole; the telescopic column 1 is hollow so that the collecting tube 3 is arranged inside the telescopic column 1, and a through hole communicating with the support tube 5 is formed on the outer wall of the collecting tube 3. Specifically, Figures 1 to 4 As shown, the support tube 5 can play an auxiliary supporting role for the cleaning tube 2, thereby improving the overall structural strength of the floating object cleaning mechanism 100 for sewage treatment of the utility model and extending the service life. Furthermore, since the support tube 5 is connected to the inner cavity of the cleaning tube 2, and a through hole connected to the support tube 5 is opened on the outer wall of the collecting tube 3, the floating objects entering the cleaning tube 2 can flow into the collecting tube 3 through the support tube 5, thereby realizing the automatic collection of the floating objects, and the structural design is ingenious and reasonable.

[0032] In one embodiment, a flange 6 is formed on the outer wall of one end of the collecting tube 3 close to the cleaning tube 2, and the flange 6 is used to abut against the outer wall of the cleaning tube 2, and a positioning block 7 is formed on the side of the flange 6 opposite to the cleaning tube 2, and a notch 8 for the positioning block 7 to extend into is formed on the cleaning tube 2 at a position corresponding to the support tube 5. Specifically, Figures 1 to 4 As shown, the flange 6 abuts against the outer wall of the cleaning tube 2, so that the collecting tube 3 can be axially limited in the up and down directions, and the structural design is simple and reasonable. Furthermore, since a positioning block 7 is formed on the side of the flange 6 relative to the cleaning tube 2, and a notch 8 for the positioning block 7 to extend into is opened at the position corresponding to the support tube 5 on the cleaning tube 2, when the collecting tube 3 is installed on the telescopic column 1, the through hole on the collecting tube 3 is aligned with the support tube 5, so that the floating objects can flow into the collecting tube 3 through the support tube 5 and the through hole, which is not only convenient for the staff to install the collecting tube 3, but also can play a role in circumferential limiting the collecting tube 3, maintain the uniqueness of the installation position of the collecting tube 3, and is reliable in use.

[0033] In one embodiment, if Figure 2 and Figure 3As shown, end caps 9 are detachably mounted at both ends of the collecting barrel 3. It can be understood that the collecting barrel 3 and the two end caps 9 can be detachably connected in a manner of snap connection or threaded connection, which not only facilitates the staff to open or close the end caps 9, but also facilitates the cleaning of floating objects in the collecting barrel 3.

[0034] In one embodiment, if Figure 2 and Figure 3 As shown, a slope 10 is formed on the bottom surface of the inner cavity of the cleaning tube 2, and the slope 10 is inclined downward toward the direction close to the support tube 5, and the length of the slope 10 is greater than the length of the through groove 4. It can be understood that the slope 10 can improve the fluidity of floating objects in the cleaning tube 2, which is conducive to discharging the floating objects into the collecting tube 3, effectively avoiding the accumulation of floating objects in the cleaning tube 2, and the structural design is ingenious and reasonable.

[0035] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
