Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment devices, and in particular to a primary wastewater filtration device that facilitates cleaning of the mesh. Background Technology

[0002] Wastewater treatment and reuse can greatly improve the utilization rate of water resources and reduce water waste. When wastewater is treated and reused, it first needs to be pretreated. Generally, filtration is used to remove or reduce suspended solids, colloids, or larger impurities in the water to a certain extent. When pre-treated water is filtered, the mesh is often large, and some impurities, colloids, and suspended solids can easily get stuck in the mesh. Especially for closed box-type pretreatment structures that are not pools or tanks, it is necessary to manually open the cleaning door and knock and pull out the internal mesh layer with considerable force, which is quite troublesome. Utility Model Content

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A primary wastewater filtration device for easy cleaning of mesh openings includes a filter box and an enlarged-pore filter layer. The enlarged-pore filter layer is horizontally spaced inside the filter box. A tray is placed inside the filter box below the enlarged-pore filter layer. The enlarged-pore filter layer consists of a gate-shaped frame and several parallel internal partitions arranged within the gate-shaped frame. Each internal partition has a corresponding center hole and a side limiting hole. A center enlarged-pore post is inserted into the center hole, and a partition post is inserted into the side limiting hole. A screw-in lug is installed on the outermost internal partition, and a side screw is screwed into the screw-in lug. One end of the side screw is rotatably installed on the gate-shaped frame. A spring is sleeved on the center enlarged-pore post between two adjacent internal partitions. A vertical partition is installed between the gate-shaped frame and the top side wall of the filter box.

[0006] Furthermore, a motor is installed on the outside of the filter box, and one end of the side lead screw extends to the outside of the filter box and is connected to the motor.

[0007] Furthermore, the side wall of the filter box is provided with a drawer hole, and one end of the drawer extends through the drawer hole to the outside of the filter box and is equipped with a sealing baffle.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] like Figure 1-2 As shown, a primary wastewater filtration device that facilitates cleaning of the mesh consists of a filter box 1 and an enlarged pore filter layer 2.

[0020] The perforated filter layer 2 is horizontally spaced inside the filter box 1. A tray 4 is placed inside the filter box 1 below the perforated filter layer 2 for cleaning and pulling out filtered debris.

[0021] The expanded pore filter layer 2 consists of a gate frame 5 and several parallel frame partitions 6 arranged inside the gate frame 5. Each of the frame partitions 6 has a corresponding central hole and a side limiting hole. A central expanded pore column 8 is inserted into the central hole, and a partition column 7 is inserted into the side limiting hole. The partition column 7, the central expanded pore column 8, and the frame partitions 6 form a mesh layer for primary filtration of larger impurities in wastewater.

[0022] A screw-in lug 11 is installed on the outermost inner frame partition 6. A side screw 10 is screwed into the screw-in lug 11. One end of the side screw 10 is rotated and installed on the door frame 5. A spring 9 is sleeved on the central enlarged hole column 8 between two adjacent inner frame partitions 6. After the spring 9 is compressed, the distance between two adjacent inner frame partitions 6 becomes smaller.

[0023] A vertical partition 3 is installed between the top side wall of the door frame 5 and the filter box 1.

[0024] like Figure 1-2 As shown, this utility model also discloses the following more optimized specific structures:

[0025] A motor 13 is installed on the outside of the filter box 1, and one end of the side lead screw 10 extends to the outside of the filter box 1 and is connected to the motor 13.

[0026] The side wall of the filter box 1 is provided with a drawer hole. One end of the tray 4 extends through the drawer hole to the outside of the filter box 1 and is equipped with a sealing baffle 19, which is used to block the drawer hole and pull out the tray 4.

[0027] A caster 14 is installed on the bottom side of the tray 4 away from the drawer hole, and a ball bearing 15 is installed on the bottom of the drawer hole to facilitate the sliding of the tray 4.

[0028] A scraper bracket 20 is installed on the top of the side of the tray 4 away from the drawer hole.

[0029] The sealing baffle 19 is equipped with fastening bolts 18, which can be rotated to tighten the sealing baffle 19 and facilitate cleaning.

[0030] The side wall of the filter box 1 is equipped with an outlet pipe 17 and an inlet pipe 16. The inlet pipe 16 is located outside the area enclosed by the door frame 5, the vertical partition 3, and the top wall of the filter box 1.

[0031] The bottom of the side wall of the filter box 1 is provided with a wastewater hole, and a cleaning valve 12 is installed on the wastewater hole to facilitate cleaning and discharging of wastewater.

[0032] like Figure 1-2The primary wastewater filtration device shown is mainly used for primary filtration of wastewater. After the wastewater is discharged, it needs to enter other devices for secondary filtration. The primary filtration is mainly for filtering larger wastes. There are multiple partition columns. Wastewater enters the filter box 1 through the inlet pipe 16, passes through the enlarged filter layer 2, and enters the area enclosed by the door frame 5, the vertical partition layer 3, and the top wall of the filter box 1. It is then discharged through the outlet pipe 17, thus achieving primary filtration.

[0033] During filtration, larger waste particles are blocked below the expanded-pore filter layer 2. When cleaning is required, the water inlet is stopped, excess wastewater is discharged, and waste accumulates in the tray 4. Some waste particles may get stuck on the expanded-pore filter layer 2. The motor 13 is started, which increases the spacing between the partitions in the frame, causing the waste to fall off. At the same time, some waste particles are knocked off by the scraper as the tray moves, preventing waste particles from getting stuck.

[0034] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
