Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a bar screen for wastewater treatment. Background Technology

[0002] A bar screen is a solid-liquid separation device that can continuously remove impurities from fluids. It is an indispensable special equipment in the production processes of industries such as urban sewage treatment, waterworks, power plant inlets, textiles, food processing, papermaking, and leather. It is currently the most widely used solid-liquid screening equipment in China.

[0003] Commercially available bar screens are usually bolted directly to the sewage tank; however, there are many types of sewage tanks with varying depths; when filtering deeper sewage tanks, the bar screen is often too short to reach the bottom of the tank, and some debris can easily flow through the bottom of the bar screen, resulting in poor cleaning performance.

[0004] Therefore, we propose a bar screen for wastewater treatment to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bar screen for sewage treatment, comprising a frame, wherein an active roller and several driven rollers are rotatably mounted inside the frame, one end of the active roller is connected to a drive motor mounted on the side of the frame, and the same bar screen is driven and mounted on the active roller and the several driven rollers; mounting seats are symmetrically rotatably mounted on both sides of the frame, and a drive structure connected to the frame is mounted on the mounting seat, and the drive structure is used to drive the frame to rotate about the axis of the mounting seat.

[0007] Furthermore: the drive structure includes a mounting plate installed on the side of the frame and a mounting bracket rotatably mounted on the mounting plate, and a first electric telescopic rod is installed on the mounting bracket. The telescopic end of the first electric telescopic rod is equipped with a rotating sleeve, and the rotating sleeve is fitted inside the rotating shaft, which is fixed inside the mounting base.

[0008] Furthermore: the drive structure includes a second electric telescopic rod mounted on the mounting base and a drive shaft fixed to the telescopic end of the second electric telescopic rod; the side of the frame is fixed with a guide groove that is slidably connected to the drive shaft.

[0009] Furthermore, the two inner sidewalls of the frame are respectively equipped with limiting rods for limiting the position of the grid mesh.

[0010] Furthermore, the mounting base has several mounting holes, and locking bolts are installed inside the mounting holes.

[0011] The beneficial effects of this utility model are:

[0012] This utility model has a mounting base rotatably installed on the side of the frame and a drive structure installed on the mounting base. The drive structure can drive the frame to rotate, thereby adjusting the tilt angle of the frame according to the depth of the sewage tank, so that the bottom of the bar screen comes into contact with the bottom of the sewage tank, preventing impurities in the sewage from flowing through the bottom of the bar screen, thereby improving the sewage cleaning effect.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0020] A bar screen for wastewater treatment includes a frame 1. Inside the frame 1, a drive roller 2 and several driven rollers 3 are rotatably mounted, with the drive roller 2 positioned at the top. The same bar screen 5 (which is already in the prior art and will not be described in detail here) is driven onto the drive roller 2 and the several driven rollers 3. The bar screen 5 is used to clean impurities in the wastewater. A drive motor 4 is installed through one side of the drive roller 2, passing through the frame 1. The drive motor 4 is installed on the side of the frame 1 and drives the drive roller 2.

[0021] Mounting seats 6 are symmetrically mounted on the two outer sides of the frame 1, allowing the frame 1 to rotate along the axes of the two mounting seats 6, thus enabling adjustment according to sewage tanks of different depths and improving the performance of the bar screen. Several mounting holes 9 are provided on the mounting seats 6, and multiple fixing bolts pass through the mounting holes 9 and connect to the edge of the sewage tank, thereby fixing the mounting seats 6 and preventing the frame 1 from loosening during use. A drive structure 7 is mounted on one end of the mounting seat 6, and one end of the drive structure 7 is connected to the side wall of the frame 1, thus driving the frame 1.

[0022] Limiting rods 8 are fixed to the two inner walls of the frame respectively. The limiting rods 8 are used to drag the edge of the grid 5 to prevent the grid 5 from becoming loose during use.

[0023] When installing the bar screen, first place the lower part of the frame 1 in the sewage tank, and then use fixing bolts to thread them through the mounting holes 9 to the edge of the sewage tank to fix it. If the sewage tank is relatively deep, the drive structure 7 can be activated (the principle of the drive structure 7 can be implemented according to the following embodiment one or embodiment two). The drive structure 7 can drive the frame 1 to rotate along the axis of the mounting base 6, so as to adjust according to the sewage tank of different depths and improve the use effect of the bar screen.

[0024] When used in shallower sewage tanks: because the angle of inclination between the frame 1 and the ground is small, the impurities in the bar screen 5 are less likely to fall off when cleaning the sewage, further improving the performance.

[0025] It should be noted that the driving structure 7 has two forms, which can be any one of the following embodiments one or two:

[0026] Example 1

[0027] The first type of drive structure: The drive structure 7 includes a mounting plate 711 fixed on the side of the frame 1. A mounting bracket 712 with a "U" shaped cross section is rotatably mounted at the center of the mounting plate 711. A first electric telescopic rod 713 is mounted on the mounting bracket 712. A rotating sleeve 714 is fixed to the telescopic end of the first electric telescopic rod 713. The rotating sleeve 714 is rotatably mounted on a rotating shaft 715. The two ends of the rotating shaft 715 are respectively fixedly connected to the inner side wall of the mounting base 6.

[0028] When adjusting the rotation of the frame 1: the first electric telescopic rod 713 is activated. The telescopic end of the first electric telescopic rod 713 can drive the rotating sleeve 714 to move and rotate inside the rotating shaft 715. During the extension or retraction process, the first electric telescopic rod 713 can drive the mounting bracket 712 to rotate on the mounting plate 711, so that the mounting plate 711 can move and drive the frame 1 to rotate along the axis of the mounting seat 6, thereby adjusting the tilt angle of the frame 1.

[0029] Example 2

[0030] The second type of drive structure: The drive structure 7 includes a second electric telescopic rod 721 installed in the mounting base 6. The second electric telescopic rod 721 is fixed with a drive shaft 722. The side of the frame 1 is provided with a guide groove 723 along the length direction, and the drive shaft 722 is slidably installed inside the guide groove 723.

[0031] When adjusting the rotation of the frame 1: Activate the second electric telescopic rod 721. The telescopic end of the second electric telescopic rod 721 can drive the drive shaft 722 to move up and down, so that the drive shaft 722 can slide in the guide groove 723, thereby driving the frame 1 to rotate around the axis of the mounting base 6, thereby adjusting the tilt angle of the frame 1.
