Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a multi-stage screening wastewater treatment device. Background Technology

[0002] Wastewater treatment is divided into two parts: chemical treatment and physical filtration. Typically, particulate matter in the wastewater is filtered out first to facilitate subsequent chemical additions. In existing wastewater filtration processes, multi-stage screening is usually used to separate the filter media of different sizes for easier processing. However, the structure of existing multi-stage screening devices is relatively fixed, and the size of the internal screen holes is fixed and cannot be adjusted. As a result, the screening device may not be able to effectively meet the screening requirements for wastewater treatment with different screening needs, leading to the filter media being classified differently from the intended categories.

[0003] Therefore, we propose a multi-stage screening wastewater treatment device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-stage screening wastewater treatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-stage screening wastewater treatment device includes a set of screening frames, the screening frames being matched in size, a set of longitudinally penetrating screen holes being opened on the lower end face of each screening frame, an adjusting plate being provided on the lower side of each screening frame for adjusting the size of the screen holes, an adjusting mechanism being provided between the adjusting plate and the screening frame, a set of connecting rods being rotatably connected to the side wall of each screening frame, the upper end of each connecting rod extending to the outside of the upper screening frame, and an insert frame being provided on the side wall corresponding to the position of the upper screening frame, and a synchronizing rod being provided on the outside of the adjusting mechanism.

[0007] Preferably, the screening frame is designed in a box shape to collect the screened filter material.

[0008] Preferably, the size of the sieve holes in a set of sieve frames gradually decreases from top to bottom.

[0009] Preferably, guide rails are connected to both sides of the lower end face of the screening frame, the two ends of the adjusting plate extend into the guide rails, and the inner wall surface of the guide rails is covered with a smooth layer.

[0010] Preferably, the adjusting mechanism includes a sliding opening on the side wall of the guide rail, a toothed plate is connected to the side wall of the adjusting plate, and the outer end of the toothed plate extends outward through the sliding opening. Rotary teeth are rotatably connected to the side wall of the screening frame, and the rotary teeth mesh with the toothed plate.

[0011] Preferably, the upper end of the connecting rod extends into the insert frame, and pin holes are provided on the side walls of the connecting rod and the insert frame corresponding to each other, with positioning pins inserted into the pin holes.

[0012] Preferably, a slot is provided on the side wall of the toothed plate, the synchronizing rod is disposed in the slot, and the length of the synchronizing rod can be adjusted by thread.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In use, this invention filters waste and impurities from wastewater using the screening frames. Multiple screening frames arranged vertically allow for multi-stage screening. The detachable design of the screening frames allows for the installation of different numbers of frames to meet varying screening requirements. The interaction of the rotating teeth and toothed plates adjusts the position of the adjusting plate and the screening frames, controlling the overlap of the screen holes and thus adjusting the size of the screen holes to meet the multi-stage screening needs of different wastewater types. Simultaneously, the synchronizing rod moves the adjusting plates of multiple screening frames synchronously, allowing for synchronized adjustment of the screen hole specifications. This ensures the screen holes are enlarged or reduced by the same size, guaranteeing effective staged screening without compromising the ability to individually adjust individual adjusting plates as needed.

[0024] Reference Figure 1-4 A multi-stage screening wastewater treatment device includes a set of screening frames 1, which are matched in size. The screening frames 1 are box-shaped and used to collect the screened filter material. After filtration, the material is stored for subsequent processing. A set of longitudinally penetrating screen holes 2 are opened on the lower end face of the screening frames 1. The size of the screen holes 2 in the set of screening frames 1 gradually decreases from top to bottom, filtering the wastewater step by step, first filtering out large particles and then filtering out small particles.

The size of the screen holes 2 on the adjustment plate 3 is the same as the size of the screen holes 2 on the corresponding screening frame 1. Guide rails 301 are connected to both sides of the lower end face of the screening frame 1 to guide the movement direction of the adjustment plate 3. Both ends of the adjustment plate 3 extend into the guide rails 301, and the inner wall surface of the guide rails 301 is covered with a smooth layer to facilitate sliding cooperation between the two and prevent the adjustment plate 3 from getting stuck.

Different numbers of screening frames 1 can be installed according to different screening requirements.

[0028] A synchronizing rod 7 is provided on the outer side of the adjusting mechanism 4. A slot 701 is provided on the side wall of the toothed plate 402. The synchronizing rod 7 is set in the slot 701, and the length of the synchronizing rod 7 can be adjusted by thread.
