Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a bar screen cleaner that is easy to maintain. Background Technology

[0002] A bar screen is a specialized water treatment device that can continuously and automatically intercept and remove debris of various shapes from fluids. Floating garbage and other impurities may exist in the water during the daily operation of channels, requiring the removal of these by a bar screen. Over time, if the wastewater contains excessive or large impurities exceeding the bar screen's processing capacity, the gaps in the bar screen may become clogged. Furthermore, the presence of large stones, metal objects, or other hard objects in the wastewater can damage parts of the bar screen. These situations necessitate the intervention of the bar screen.

[0003] When existing bar screens become clogged or damaged, the machine is often shut down for extended periods to replace the entire outer bar screen, or even the entire machine itself. Replacing the entire outer bar screen increases equipment costs, especially for large, high-precision bar screens, which are quite expensive. This replacement cost places a significant financial burden on relevant departments. Furthermore, disassembling the entire outer bar screen is complex, time-consuming, and labor-intensive. The extended downtime required for replacement increases maintenance time and equipment downtime costs, impacting normal bar screen operation. Therefore, we propose a bar screen design that is easier to maintain to address these issues. Utility Model Content

[0004] This utility model provides a bar screen cleaning machine that is easy to maintain. It solves the problem that when the gaps of the bar screen are blocked or damaged, the cleaning machine will stop working for a long time. Replacing the entire bar screen around the cleaning machine increases equipment costs, and the replacement process is complicated, time-consuming and labor-intensive. The long downtime increases the time cost of maintenance and the downtime cost of the equipment, which affects the normal operation of the cleaning machine.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a bar screen cleaning machine that is easy to maintain, including a channel and a cleaning machine. The cleaning machine includes three sprocket drive assemblies and multiple bar screens. The middle sprocket drive assembly is provided with multiple mounting components, and the sprocket drive assemblies on both sides are provided with multiple side pins. A receiving rod is provided between the mounting components and the side pins, and both ends of the bar screen abut against different receiving rods.

[0006] In the preferred embodiment, the sludge removal machine is installed at an angle on the channel, and a conveyor belt is provided at the top of the channel, with one end of the sludge removal machine located on the conveyor belt.

[0007] In a preferred embodiment, the sprocket drive assembly includes two sprockets, with a meshing chain between the two sprockets. The chain includes multiple links, and each link has two through holes.

[0008] In a preferred embodiment, the mounting assembly includes a bidirectional screw with sleeves at both ends. The bidirectional screw abuts against the through hole of the intermediate sprocket drive assembly, and one end of the sleeve has a threaded hole.

[0009] In the preferred embodiment, the threaded hole engages with the bidirectional screw, a nut is provided between the rod sleeve and the intermediate sprocket drive assembly, and one end of the receiving rod abuts against the rod sleeve.

[0010] In a preferred embodiment, the side pin includes a pin shaft with a rotating seat at one end. The pin shaft abuts against the through holes on the sprocket drive assemblies on both sides. One end of the pin shaft has an external thread, and a second nut is provided on the pin shaft. The second nut engages with the external thread and abuts against the chain of the sprocket drive assemblies on the side.

[0011] In the preferred embodiment, the grid has long mesh openings on both sides, and the receiving rod passes through the long mesh openings.

[0012] In the preferred embodiment, the sprockets with two ends of the three sprocket drive assemblies are all connected by a drive shaft, and one end of one of the drive shafts is equipped with a motor.

[0013] The beneficial effects of this utility model are as follows: The cleaning machine is placed at an angle on the channel. By driving the motor, multiple sprocket transmission components are rotated, which causes multiple grids to move, so that the floating garbage at the bottom of the channel is transported to the top of the cleaning machine, and the floating garbage falls into the conveyor belt. Workers collect the floating garbage at one end of the conveyor belt.

[0014] When the grid is partially blocked or damaged, stop the cleaning machine and conveyor belt. Rotate the sleeves of the two mounting components at one end of the blocked or damaged grid to move them onto the receiving rods. This disengages the receiving rods on both sides of the grid from the central sprocket drive assembly. Raise one end of the receiving rods so that the two receiving rods rotate relative to the side pins, causing the grid to tilt. Remove the sleeves and grid from the two receiving rods. Replace the grid with a new one on the two receiving rods and install the sleeves. Rotate the receiving rods to level the replaced grid. Rotate the sleeves to engage with the double-acting screw. The grid reinstallation is complete. Start the motor and conveyor belt, and the entire equipment will begin operation.

[0015] The overall structure is simple, and replacing parts of the grid is quick and convenient. It is easy for staff to operate, saving a lot of time and downtime. This reduces maintenance costs for staff and equipment downtime, and avoids affecting normal pollution removal operations. When a part of the grid is blocked or damaged, it is not necessary to replace all the surrounding grids or the entire pollution removal machine, saving a lot of economic costs and making it highly valuable for promotion.
