Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment, and in particular to a sewage treatment device that facilitates the removal of scum. Background Technology

[0002] In the process of treating industrial wastewater and domestic sewage, a large amount of scum will form on the surface of the sewage. Its composition is complex, including grease, fiber, suspended particulate matter, etc. Some of the scum is sticky due to its high organic content. If it is not treated in time, the scum will hinder the contact between water and air and affect the aeration efficiency in the sewage treatment process. Therefore, there is a need for a sewage treatment device that can easily handle scum.

[0003] A wastewater treatment tank, authorized by publication number CN222274201U, includes a treatment tank, sliding tracks, a cleaning component, and a drive component. The sliding tracks include at least four tracks, with at least two tracks respectively located at the left and right ends of the treatment tank. The cleaning component includes a scum collection piece, an upper fixed rod, and a lower fixed rod. The scum collection piece has an opening on one side and is connected to the upper and lower fixed rods. The scum collection piece is slidably connected to the sliding tracks via the upper and lower fixed rods. The drive component is electrically connected to the cleaning component. This application uses the drive component to move the scum collection piece along the sliding tracks, from the front end of the treatment tank to the rear end to collect wastewater scum. Workers only need to clean the scum from the scum collection piece. The cleaning component improves the cleaning efficiency of the wastewater treatment tank compared to manual cleaning, as it removes scum more thoroughly.

[0004] However, in the aforementioned type of sewage treatment tank, sticky scum adheres to the scum collection component, and long-term accumulation can easily lead to blockage of the through holes, making maintenance inconvenient. The device relies on staff to clean the sewage scum inside the scum collection component, which is inefficient.

[0005] To address the aforementioned problems, a wastewater treatment device that facilitates the removal of scum is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a sewage treatment device that facilitates the treatment of scum, so as to solve the problem of the existing sewage treatment devices that facilitate the treatment of scum mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a sewage treatment device for easy scum removal, comprising a treatment tank, wherein a scum collection assembly is provided on the inner wall of the treatment tank, and a scum discharge assembly is provided on the outer side of the scum collection assembly;

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example

[0028] like Figure 1-4 As shown, the system includes a treatment tank 1, a slag collection assembly 2 on the inner wall of the treatment tank 1, and a slag discharge assembly 3 on the outer side of the slag collection assembly 2. The slag collection assembly 2 includes an installation frame 201 installed on the inner wall of the treatment tank 1, a slag collection box 202 on the inner wall of the installation frame 201, a top plate 203 integrally formed on the top of the slag collection box 202, two sets of installation columns 204 on the two sides of the top of the installation frame 201 respectively, and the installation columns 204 are rotatably connected to the installation frame 201. The surface of the top plate 203 has a through groove 205 that matches the size of the installation columns 204. The slag collection assembly 2 also includes a square groove 206 opened at one end of the installation frame 201, a bottom groove 207 opened at the bottom of the slag collection box 202, five sets of filter screens 208 installed on one side of the slag collection box 202, and a shovel plate 209 integrally formed at the opening at one end of the slag collection box 202.

[0029] It should be noted that, in this embodiment, during scum collection, the drive components on both sides of the mounting frame 201, which cooperate with the guide rail, are first activated to drive the scum collection assembly 2 to move along the guide rail of the treatment tank 1 towards the scum accumulation area. The shovel plate 209 at one end of the scum collection box 202 moves with the scum collection assembly 2, shoveling the scum from the water surface into the scum collection box 202. After the scum enters the scum collection box 202, since the square channel 206 corresponds to the filter screen 208, the sewage flows back to the treatment tank 1 through the five sets of filter screens 208 on one side of the scum collection box 202, while the scum is intercepted by the filter screens 208 and remains in the scum collection box 202. During this process, the bottom of the scum collection box 202... The bottom trough 207 of the part is connected to the inner wall of the closed opening and closing plate 301, ensuring that the scum can be temporarily stored at the bottom of the scum collection box 202. When the scum collection box 202 moves from one end of the treatment pool 1 to the other end of the treatment pool 1, the scum in the treatment pool 1 is collected in the semi-circle formed by the bottom of the scum collection box 202 and the opening and closing plate 301. Then the driving component drives the scum collection assembly 2 to continue moving along the guide rail. According to the preset arc of the guide rail, it is guided to the top of the collection box. The scum collection assembly 2 gradually moves from the water surface area of ​​the treatment pool 1 to the top of the collection box. At this time, the opening of the bottom trough 207 faces the collection box, ensuring that the scum can fall accurately into the collection box when the scum is discharged.

[0030] Furthermore, the mounting frame 201 and the slag collection box 202 are limited by the cooperation of the mounting column 204 and the through groove 205 to prevent the slag collection component 2 from tilting or falling off when moving along the arc of the guide rail, ensuring that the slag will not leak out during the transfer process. When there is a lot of slag on the inner wall of the slag collection box 202 or the filter screen 208, the slag collection box 202 can be deeply cleaned. Rotate the mounting column 204 at the top of the mounting frame 201 to make the mounting column 204 disengage from the through groove 205 of the top plate 203, and remove the slag collection box 202 from the mounting frame 201. The filter screen 208 is a detachable design. After removing the filter screen 208, directly clean the residual slag on the inner wall of the slag collection box 202 and the blockage of the filter screen 208. After cleaning, reinstall the filter screen 208 on the slag collection box 202, put the slag collection box 202 back into the mounting frame 201, rotate the mounting column 204 to re-enter the through groove 205, complete the fixation, and resume use.

[0031] The slag collection component 2 is installed inside the treatment tank 1. The mating parts on both sides of the mounting frame 201 engage with the guide rails on the side wall of the treatment tank 1 to ensure that the slag collection component 2 can move stably along the guide rails. The collection box at one end of the treatment tank 1 is placed in place, and its position matches the curvature of the end of the guide rail. The engagement between the mounting frame 201 and the guide rail, as well as the linkage of the drive components, are mature technologies in the existing field. Therefore, not all of them are shown in the attached drawings, and they will not be described in detail here.

[0032] like Figure 5 , 6As shown, the slag discharge assembly 3 includes two sets of opening and closing plates 301 installed at the bottom of the slag collection box 202, and the opening and closing plates 301 form a semi-circular structure. The slag discharge assembly 3 also includes connecting plates 302 installed on both sides of the top of the opening and closing plates 301. A cylinder 303 is provided on one side of the connecting plate 302. A limiting plate 304 is provided on one side of the two sets of cylinders 303 on the same side of the opening and closing plate 301. Two sets of limiting grooves 305 are opened on the surface of the limiting plate 304, and the cylinder 303 is slidably connected to the limiting groove 305. The slag discharge assembly 3 also includes receiving grooves 306 opened on both sides of the bottom of the slag collection box 202. A rotating shaft 307 is installed on the side wall of the opening and closing plate 301, and the rotating shaft 307 is rotatably connected to the protruding part at the bottom of the slag collection box 202.

[0033] It should be noted that in this embodiment, after the slag collection assembly 2 is stably positioned above the collection box, the driving component connected to the top of the limiting plate 304 is activated. This component can be an electric push rod. The limiting plate 304 is driven to move downward along the side wall of the slag collection box 202. When the limiting plate 304 moves downward, the limiting groove 305 on its surface moves synchronously. Since the cylinder 303 is connected to the connecting plate 302 at the top of the opening and closing plate 301 and is slidably connected to the limiting groove 305, the tilt angle of the limiting groove 305 will push the cylinder 303 to move to both sides. Then, the opening and closing plate 301 will be driven to rotate outward around the rotating shaft 307 through the connecting plate 302. After the opening and closing plate 301 is opened, the bottom groove 207 at the bottom of the slag collection box 202 is connected to the outside. The slag stored in the bottom groove 207 and the closed area of ​​the opening and closing plate 301 falls into the collection box below through the gap of the opened opening and closing plate 301 under the action of gravity.

[0034] Furthermore, the connecting plate 302, the cylinder 303 and the limiting plate 304 are all located in the receiving groove 306 at the bottom of the slag collection box 202 to avoid interference between the components and the treatment pool 1 or the collection box during slag discharge. The semi-circular protruding structure at the bottom of the slag collection box 202 fits against the side wall of the opening and closing plate 301 to reduce residual dead corners.

[0035] The driving component connected to the top of the limiting plate 304 can be an electric push rod, which is a mature existing technology and will not be described here.

[0036] Working principle of this utility model:

[0037] Refer to the instruction manual appendix Figure 1-6When collecting scum, the drive components on both sides of the mounting frame 201 that cooperate with the guide rail are first activated, which drives the scum collection assembly 2 to move along the guide rail of the treatment tank 1 towards the scum accumulation area. The shovel plate 209 at one end of the scum collection box 202 moves with the scum collection assembly 2, shoveling the scum on the water surface into the scum collection box 202. After the scum enters the scum collection box 202, since the square groove 206 corresponds to the filter screen 208, the sewage flows back to the treatment tank 1 through the five sets of filter screens 208 on one side of the scum collection box 202. The scum is intercepted by the filter screens 208 and left in the scum collection box 202. During this process, the bottom groove 207 at the bottom of the scum collection box 202 is connected to the inner wall of the closed opening and closing plate 301, ensuring that the scum can be temporarily stored at the bottom of the scum collection box 202.

[0038] When the slag collection box 202 moves from one end of the treatment tank 1 to the other end of the treatment tank 1, the scum in the treatment tank 1 is collected in the semi-circle formed by the bottom of the slag collection box 202 and the opening and closing plate 301. Then the driving component drives the slag collection assembly 2 to continue moving along the guide rail. According to the preset arc of the guide rail, it is guided to the top of the collection box. The slag collection assembly 2 gradually moves from the water surface area of ​​the treatment tank 1 to the top of the collection box. At this time, the bottom trough 207 opening faces the collection box to ensure that the scum can fall accurately into the collection box when the slag is discharged.

[0039] Once the slag collection assembly 2 is stably positioned above the collection box, the drive component connected to the top of the limiting plate 304, which can be an electric push rod, is activated to drive the limiting plate 304 to move downward along the side wall of the slag collection box 202. When the limiting plate 304 moves downward, the limiting groove 305 on its surface moves synchronously. Since the cylinder 303 is connected to the connecting plate 302 at the top of the opening and closing plate 301 and is slidably connected to the limiting groove 305, the tilt angle of the limiting groove 305 will push the cylinder 303 to move to both sides, and then drive the opening and closing plate 301 to rotate outward around the rotating shaft 307 through the connecting plate 302. After the opening and closing plate 301 is opened, the bottom groove 207 at the bottom of the slag collection box 202 is connected to the outside. The slag stored in the bottom groove 207 and the closed area of ​​the opening and closing plate 301 falls into the collection box below through the gap of the opened opening and closing plate 301 under the action of gravity.

[0040] When there is a lot of floating scum on the inner wall of the slag collection box 202 or the filter screen 208, the slag collection box 202 can be deeply cleaned. Rotate the mounting column 204 at the top of the mounting frame 201 so that the mounting column 204 is dislodged from the through groove 205 of the top plate 203. Remove the slag collection box 202 from the mounting frame 201. The filter screen 208 is a detachable design. After removing the filter screen 208, directly clean the residual floating scum on the inner wall of the slag collection box 202 and the blockage of the filter screen 208. After cleaning, reinstall the filter screen 208 on the slag collection box 202, put the slag collection box 202 back into the mounting frame 201, rotate the mounting column 204 to re-enter the through groove 205 to complete the fixation, and it can be used again.
