Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a filtering device for sewage treatment. Background Art

[0002] Wastewater treatment refers to the purification process to make wastewater meet the water quality requirements for discharge into a water body or reuse. This process involves physical, chemical, biological and other treatments of wastewater containing various organic, inorganic and microorganisms generated in production, life, industry, agriculture and other activities to remove pollutants such as suspended solids, organic matter, bacteria, viruses, heavy metals, etc.

[0003] At the front end of sewage treatment, it is necessary to salvage larger debris such as floating objects in the sewage. The sewage treatment pool and the intermediate water pool are connected by a filter channel. In the prior art, a multi-level grid net is generally set in the filter channel to filter out debris.

[0004] However, in the prior art, after the debris is filtered, it is often necessary to manually salvage the debris on the grille, which is very troublesome and inefficient, and will affect the overall sewage treatment efficiency. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a filtering device for sewage treatment.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A filtering device for sewage treatment comprises a filtering channel, in which a filtering grille is fixedly installed, a guide block is movably provided in front of the filtering grille, and a water retaining plate is movably provided behind the filtering grille; a discharge chute is provided on one side of the filtering channel in front of the filtering grille, the discharge chute is communicated with the filtering channel, and a discharge plate is movably provided at the connection between the filtering channel and the discharge chute.

[0008] In addition, a preferred structure is that support columns are vertically fixed upward on both sides of the filter channel, and the tops of the support columns are connected to the top plate.

[0009] In addition, a preferred structure is that a plurality of guide rods are vertically provided through the water baffle, the guide block and the discharge plate, the bottoms of the guide rods are fixed to the filter channel, and the tops of the guide rods are fixed to the top plate.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-4A filter device for sewage treatment includes a filter channel 1, a filter grille 2 is fixedly installed in the filter channel 1, a guide block 7 is movably provided in front of the filter grille 2, and a water retaining plate 6 is movably provided behind the filter grille 2; a discharge chute 3 is provided on one side of the filter channel 1 in front of the filter grille 2, the discharge chute 3 is connected to the filter channel 1, and a discharge plate 8 is movably provided at the connection between the filter channel 1 and the discharge chute 3. By setting the filter grille 2, the debris in the filter channel 1 can be filtered. And it is worth noting that the present filter device can be set in multiple in the filter channel 1.

[0021] Among them, support columns 41 are vertically fixed upward on both sides of the filter channel 1, and the tops of the support columns 41 are connected to the top plate 4. A plurality of guide rods 5 are vertically penetrated on the water baffle 6, the guide block 7 and the discharge plate 8, the bottoms of the guide rods 5 are fixed to the filter channel 1, and the tops of the guide rods 5 are fixed to the top plate 4. Through the setting of the top plate 4, the guide rods 5 can be fixed, so that the water baffle 6, the guide block 7 and the discharge plate 8 can all be moved vertically up and down through the guide rods 5.

[0022] Among them, the first transmission rod 61, the second transmission rod 71 and the third transmission rod 81 are respectively inserted into the water baffle 6, the guide block 7 and the discharge plate 8, and the ends of the first transmission rod 61, the second transmission rod 71 and the third transmission rod 81 all pass through the top plate 4 and are connected to the driving motor. The first transmission rod 61, the second transmission rod 71 and the third transmission rod 81 are all provided with a driving motor. Through the setting of the driving motor, the transmission of the first transmission rod 61, the second transmission rod 71 and the third transmission rod 81 can be realized, so that the water baffle 6, the guide block 7 and the discharge plate 8 can be driven to move up and down by the first transmission rod 61, the second transmission rod 71 and the third transmission rod 81. It is worth noting that the first transmission rod 61, the second transmission rod 71 and the third transmission rod 81 are all provided with threads, and the threads are driven to rotate by the driving motor, so that the water baffle 6, the guide block 7 and the discharge plate 8 can be driven to move. This is a prior art and does not belong to the main technical problem solved in this technical solution. Therefore, it is not elaborated in this utility model.

[0023] The discharge chute 3 is located at one side of the filter channel 1, and the water inlet and outlet of the discharge chute 3 are respectively connected to the filter channel 1 at the front and rear sides of the filter grille 2, and a filter screen 9 is fixedly arranged on the water outlet of the discharge chute 3. The arrangement of the filter screen 9 can prevent the debris in the discharge chute 3 from re-entering the filter channel 1.

[0024] When the water baffle plate 6 and the guide block 7 move upward, the water flow in the filter channel 1 directly passes through the filter grille 2; when only the discharge plate 8 moves upward, the water flow in the filter channel 1 bypasses the filter grille 2 from the discharge trough 3. By moving the water baffle plate 6, the guide block 7 and the discharge plate 8 up and down, two different working states in the filter channel 1 can be achieved.

[0025] In the present invention, when the user needs to filter the debris in the filter channel 1, the first transmission rod 61 and the second transmission rod 71 can be used to drive the water baffle plate 6 and the guide block 7 to move upward. At this time, only the discharge plate 8 is located at the discharge trough 3 in the filter channel 1, and the water flow can directly pass through the filter grille 2 through the filter channel 1, thereby filtering the debris through the filter grille 2.

[0026] Furthermore, when the user needs to clean the debris on the filter grille 2, he only needs to lower the water baffle 6 and the guide block 7 through the first transmission rod 61 and the second transmission rod 71, and then drive the discharge plate 8 to move upward through the third transmission rod 81. At this time, the water flow in the filter channel 1 is diverted to one side of the filter grille 2 through the guide block 7, and due to the setting of the water baffle 6, the water flow cannot pass directly through the filter grille 2. At this time, the water flow flushes through the filter grille 2 and flows into the discharge trough 3, so that the debris on the filter grille 2 can be flushed into the discharge trough 3, so that the debris can be cleaned. Finally, the water flow in the discharge trough 3 can flow back into the filter channel 1 through the filter net 9.

[0027] In the present invention, the debris in the water flow in the filter channel 1 can be filtered through the filter grille 2, and the debris on the filter grille 2 can be cleaned into the discharge trough 3 through the coordinated arrangement between the water baffle plate 6, the guide block 7 and the discharge plate 8. This cleaning method is quick and convenient, and improves the sewage treatment efficiency.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
