Description

Technical Field

[0002] Sewage treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse. The Chinese utility model patent, authorization announcement number "CN217399890U", discloses a gate for sewage treatment, including a gate and a blocking structure. The gate includes a gate frame, a gate plate is provided in the gate hole of the gate frame, and the gate plate is slidably connected to the gate frame. The blocking structure is located in front of the gate hole of the gate frame. The blocking structure consists of a sliding rod, a pipe rack and a blocking frame. There are two sliding rods, and the two sliding rods are respectively located on both sides of the gate hole of the gate frame. The sliding rods are placed vertically and the upper and lower ends of the sliding rods are fixedly connected to the gate frame through the protruding seat. By providing a blocking structure in front of the gate, the blocking frame is kept floating on the water surface by the buoyancy of the float. The upper and lower ends of the blocking rod are respectively located at the upper and lower ends of the water level, which can effectively block suspended matter in the water when sewage is discharged. The water flow through the blocking structure is good, ensuring the normal discharge of sewage. Multiple water level marks are equidistantly provided on the sliding rod.

[0003] The above technical solution is achieved by providing an intercepting structure in front of the gate, and the buoyancy of the float is used to keep the intercepting frame floating on the water surface. The upper and lower ends of the intercepting rod are respectively located at the upper and lower ends of the water level, which can effectively block suspended matter in the water when sewage is discharged. However, the above technical solution still has certain defects. For example, the above equipment keeps the intercepting frame floating on the water surface by the buoyancy of the float. However, when the intercepting frame needs to be maintained and repaired after long-term use, the staff needs to have certain professional skills to disassemble it. This operation is complicated and difficult, which reduces the maintenance and repair efficiency of the intercepting frame and increases the workload of the staff. Utility Model Content

[0027] See also Figure 1-3 , the utility model provides a technical solution: a corrosion-resistant steel gate for sewage treatment, comprising a gate frame 1;

[0028] A limiting device is provided on the gate frame 1;

[0029] The limiting device includes a blocking frame 11, two fixed rods 5 and two sliding blocks 6. The two sliding blocks 6 are slidably sleeved on the outer wall of the corresponding fixed rod 5. The lower outer walls of the two fixed rods 5 are fixedly connected to the lower outer wall of the gate frame 1. The outer walls of the two sliding blocks 6 are fixedly connected with mounting blocks 13. The outer walls of the two mounting blocks 13 are installed with floating ball frames 10. The outer walls of the two sliding blocks 6 are provided with limiting block grooves 7. The outer walls of both ends of the blocking frame 11 are fixedly connected to the limiting blocks 8. The outer walls of the two limiting blocks 8 are respectively The two sliding blocks 6 are respectively connected to the corresponding internal sliding connections of the limit block grooves 7, and the outer walls of the opposite surfaces of the two sliding blocks 6 are threadedly connected with fixing bolts 9. The outer walls of the two limit blocks 8 are provided with fixing bolt grooves 15, and the ends of the two fixing bolts 9 close to the fixing bolt grooves 15 are threadedly extended to the inside of the fixing bolt grooves 15. The outer wall of the float frame 10 is installed with a fixing block 3, and the outer wall of the fixing block 3 is provided with a second limit block groove 12. The outer wall of the limit block on the outer wall of the blocking frame 11 is slidably connected to the inside of the second limit block groove 12.

[0030] Among them, the upper surface of the gate frame 1 is fixedly connected to the motor 4, the output end of the motor 4 rotates and extends to the interior of the gate frame 1 and is fixedly connected to the threaded rod 16, and the interior of both sides of the gate frame 1 are fixedly connected to the limit rod 14. The gate 2 is provided inside the gate frame 1, and the outer walls on both sides of the gate 2 are respectively slidably connected to the corresponding outer walls of the limit rod 14. A threaded rod groove 17 is opened on the upper surface of the gate 2, and the outer wall of the threaded rod 16 is threadedly connected to the inner part of the threaded rod groove 17.

[0031] Furthermore, when using the device, it is started by connecting an external power supply. First, a layer of oil film is covered on the surface of the gate 2 to reduce direct contact with sewage, thereby improving the corrosion resistance of the gate 2. Then, the output end of the motor 4 is rotated to drive the threaded rod 16 to rotate while driving the gate 2 to move upward. Then, the buoyancy of the float on the float frame 10 is used to make the blocking frame 11 always float on the water surface, so that suspended matter (such as branches, plastic bags, etc.) in the sewage can be intercepted during the sewage discharge process. Then, a plurality of water level marks are equidistantly provided on the fixed rod 5. When the water level rises and falls, the sliding block 6 will slide along the fixed rod 5. The water level height can be judged by observing the position of the sliding block 6 on the fixed rod 5 and combining it with the water level mark on the fixed rod 5. Then, when the blocking frame 11 needs to be removed, the fixing bolt 9 is turned to rotate so that the other end is out of contact with the inside of the fixing bolt slot 15. Then, the blocking frame 11 can be removed from the float frame 10 by pulling it, which facilitates maintenance and inspection of the blocking frame 11.

[0032] The blocking frame 11 can be removed from the float frame 10 by twisting the fixing bolt 9 in the limit device and rotating it so that the other end is out of contact with the inside of the fixing bolt groove 15, and then pulling the blocking frame 11. This facilitates the maintenance and inspection of the blocking frame 11 and avoids the need for certain special skills for the staff. The disassembly is simple and convenient, which effectively reduces the workload of the staff and improves the maintenance and inspection efficiency of the blocking frame 11. The buoyancy of the float on the float frame 10 makes the blocking frame 11 always float on the water surface, so that suspended matter (such as branches, plastic bags, etc.) in the sewage can be intercepted during the sewage discharge process, thereby avoiding the clogging of the gate 2 by suspended matter in the sewage, effectively improving the practicability and effectiveness of the equipment, and at the same time improving the work efficiency of the staff.

[0033] Working principle: First, the surface of the gate 2 is covered with a layer of oil film to reduce direct contact with sewage, which improves the corrosion resistance of the gate 2. Then, the output end of the motor 4 rotates to drive the threaded rod 16 to rotate while driving the gate 2 to move upward. Then, the buoyancy of the float on the float frame 10 makes the barrier frame 11 always float on the water surface, so that suspended matter in the sewage (such as branches, plastic bags, etc.) can be intercepted during sewage discharge. Then, a plurality of water level marks are equidistantly provided on the fixed rod 5. When the water level rises and falls, the sliding block 6 will slide along the fixed rod 5. The water level height can be judged by observing the position of the sliding block 6 on the fixed rod 5 and combining it with the water level mark on the fixed rod 5. Then, when the barrier frame 11 needs to be removed, turn the fixing bolt 9 to rotate it so that the other end is out of contact with the inside of the fixing bolt slot 15. Then pull the barrier frame 11 to remove the barrier frame 11 from the float frame 10, which is convenient for maintenance and inspection of the barrier frame 11.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
