Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an integrated wastewater treatment equipment using a rotary bar screen. Background Technology

[0002] The rotary bar screen integrated sewage treatment equipment is a compact sewage treatment device that integrates a rotary bar screen. It is mainly used to intercept and remove large solid impurities (such as branches, plastic bags, suspended solids, etc.) in sewage, providing protection for subsequent treatment processes.

[0003] Existing bar screens are installed inside water tanks, leaving gaps between them and the sides. Side baffles are typically used to block the flow of solid waste. However, when solid impurities reach the bar screen, those at the stepped bar section are conveyed away, while some still accumulate at the side baffles, failing to reach the central bar screen and leading to bacterial growth in the water. Therefore, an integrated rotary bar screen wastewater treatment system is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated wastewater treatment equipment with a rotary bar screen to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to an integrated wastewater treatment equipment using a rotary bar screen, comprising:

[0006] A stepped bar screen machine, comprising a housing and a stepped mesh screen, wherein the stepped mesh screen rotates cyclically inside the housing;

[0007] The guide assembly includes a guide plate, a slot, a first rubber strip, a first bracket, a spring post, and a second bracket. The lower end of the guide plate is hinged to both sides of the lower end of the housing. The slot is opened at one end of the guide plate near the housing. One end of the first rubber strip is fixed to the side of the housing, and the other end is inserted into the slot. The first bracket is fixed to the side of the lower end of the housing. One end of the spring post is rotatably connected to the first bracket. The second bracket is fixed to the lower end of the side of the guide plate, and the other end of the spring post is rotatably connected to the second bracket.

[0008] Furthermore, the guide assembly also includes a rubber pad, which is fixed to the other end of the guide plate away from the housing.

[0009] Furthermore, the stepped bar screen machine also includes a roller brush, which is rotatably connected to the side of the housing and located below the uppermost side of the stepped bar screen.

[0010] Furthermore, the stepped bar screen also includes a lower baffle and a side baffle. The lower baffle is fixed on the lower end of the housing away from the roller brush, and one end of the side baffle is fixed on the lower ends of both sides of the housing and located next to the guide plate.

[0011] Furthermore, the side baffle and rubber pad are attached to the inner wall of the outer water tank at the other end away from the housing.

[0012] Furthermore, it also includes a receiving component, which includes a support plate, mounting holes, waist holes, and a sliding plate. The mounting holes and waist holes are respectively opened at both ends of the support plate, and the support plate is fixed to the ends of the housing away from the guide plate on both sides by the mounting holes and bolts. The sliding plate is fixed to the waist holes by bolts and is located below the roller brush.

[0013] Furthermore, the receiving component also includes a spring sheet and a second rubber strip, one end of the spring sheet being fixed above the slide plate near the stepped mesh grid, and the second rubber strip being fixed above the spring sheet.

[0014] This utility model has the following beneficial effects:

[0015] This invention, through a guide assembly, installs a stepped bar screen in a wastewater treatment tank. A spring column on the first support pushes the second support to rotate, thereby causing the other end of the guide plate to approach the inner wall of the tank, so that the rubber pad adheres to the inner wall of the tank. As the rubber pad adheres to the inner wall of the tank, the end of the first rubber strip located in the groove slides relative to the groove. When solid impurities flow towards the stepped bar screen, the impurities located on both sides of the water trough are pushed towards the guide plate and move along the guide plate towards the center of the bar screen. This design can prevent impurities from accumulating and remaining on both sides of the bar screen, thus improving the cleaning effect. Attached Figure Description

[0025] Please see Figure 1-3 As shown, this utility model is an integrated wastewater treatment equipment using a rotary bar screen, comprising:

[0026] A stepped bar screen machine includes a housing 10 and a stepped mesh bar 11, the stepped mesh bar 11 rotating cyclically inside the housing 10;

[0027] The stepped bar screen machine also includes a roller brush 14, which is rotatably connected to the side of the housing 10 and located below the uppermost side of the stepped bar screen 11.

[0028] The stepped bar screen also includes a lower baffle 12 and a side baffle 13. The lower baffle 12 is fixed on the lower end of the housing 10 away from the roller brush 14, and one end of the side baffle 13 is fixed on the lower ends of both sides of the housing 10 and is located next to the guide plate 20.

[0029] The housing 10 provides support, the stepped mesh grid 11 is driven to rotate by a motor and pulley to transport solid impurities, the lower baffle 12 acts as a barrier to prevent impurities from flowing under the housing 10, the side baffle 13 acts as a blockage, and the roller brush 14 is used to brush off impurities on the stepped mesh grid 11.

[0030] The guide assembly includes a guide plate 20, a slot 22, a first rubber strip 23, a first bracket 24, a spring post 25, and a second bracket 26. The lower end of the guide plate 20 is hinged to both sides of the lower end of the housing 10. The slot 22 is opened at one end of the guide plate 20 near the housing 10. One end of the first rubber strip 23 is fixed to the side of the housing 10, and the other end is inserted into the slot 22. The first bracket 24 is fixed to the side of the lower end of the housing 10. One end of the spring post 25 is rotatably connected to the first bracket 24. The second bracket 26 is fixed to the lower end of the side of the guide plate 20, and the other end of the spring post 25 is rotatably connected to the second bracket 26.

[0031] The guide assembly also includes a rubber pad 21, which is fixed to the other end of the guide plate 20 away from the housing 10;

[0032] The other end of the side baffle 13 and the rubber pad 21, away from the housing 10, is attached to the inner wall of the outer water tank;

[0033] The guide plate 20 serves as a guide, the rubber pad 21 allows the guide plate 20 to better fit the inner wall of the pool, the slot 22 is used to connect the first rubber strip 23, the first rubber strip 23 serves as a block, the first bracket 24 and the second bracket 26 serve as a connection, and the spring column 25 has a telescopic function.

[0034] Working principle:

[0035] The stepped bar screen is installed inside the sewage treatment tank. The spring column 25 on the first support 24 pushes the second support 26 to rotate, thereby causing the other end of the guide plate 20 to approach the inner wall of the tank, so that the rubber pad 21 is attached to the inner wall of the tank. As the rubber pad 21 is attached to the inner wall of the tank, one end of the first rubber strip 23 located in the groove 22 slides relative to the other end within the groove 22. When solid impurities flow towards the stepped bar screen, the impurities located on both sides of the trough are pushed towards the guide plate 20 and move along the guide plate 20 towards the center of the bar screen.

[0036] This step prevents impurities from accumulating and remaining on both sides of the bar screen, thus improving the cleaning effect.

[0037] Please see Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The receiving component includes a support plate 30, mounting holes 31, waist holes 32 and a sliding plate 33. The mounting holes 31 and waist holes 32 are respectively opened at both ends of the support plate 30. The support plate 30 is fixed to the ends of the housing 10 away from the guide plate 20 by the mounting holes 31 and bolts. The sliding plate 33 is fixed to the waist holes 32 by bolts and is located below the roller brush 14.

[0039] The receiving component also includes a spring sheet 34 and a second rubber strip 35. One end of the spring sheet 34 is fixed above the slide plate 33 near the end of the stepped mesh grid 11, and the second rubber strip 35 is fixed above the spring sheet 34.

[0040] The support plate 30 serves as a support and connection, the mounting hole 31 is used to fix the support plate 30, the waist hole 32 facilitates the installation of the slide plate 33, the slide plate 33 serves as a blocking function, the spring plate 34 has a reset function, and the second rubber strip 35 serves as a blocking function.

[0041] Working principle:

[0042] When solid impurities on the lower stepped mesh grating 11 rise and rotate to the roller brush 14, they are brushed off by the roller brush 14. However, a small amount will remain on the stepped mesh grating 11, and some impurities that remain on the roller brush 14 and do not fall off in time will fall onto the slide plate 33 or the second rubber strip 35 as the grating rotates downwards, and slide down the slide plate 33. The stepped mesh grating 11 continues to move downwards. When it reaches the second rubber strip 35, it will press down the second rubber strip 35, causing the spring plate 34 to be compressed. After the stepped mesh grating 11 moves past the second rubber strip 35, the spring plate 34 will spring the second rubber strip 35 back up.

[0043] This step prevents small amounts of impurities from falling back into the pool, reducing the probability of secondary pollution.
