Description

Technical Field

[0001] This utility model relates to the field of bar screen technology, specifically a high-density brush bar screen. Background Technology

[0002] Bar screens are typically placed at an angle on the main gravity-flow water channel before the sewage lift pump's collection tank. They are used to block and intercept large solid objects in the sewage that are suspended or floating, in order to prevent valves, pipes, pumps, surface aerators, sludge suction pipes, and other subsequent treatment equipment from becoming clogged or damaged.

[0003] In existing bar screens, although the screenings are intercepted and driven by the bar screen during long-term use, some screenings will get stuck in the gaps inside the device, preventing them from being properly discharged into the screw conveyor. At the same time, through the cooperation of sewage and the device, the screenings will be washed away and discharged back into the sewage, reducing the overall effectiveness of the device.

[0020] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides a technical solution, please refer to [link / reference]. Figure 1 and Figure 2 The high-density brush bar screen machine includes: a cleaning roller 1, a motor 2, a water pump 3, and a bar screen device 8. The cleaning roller 1 is mounted on the outside of the bar screen device 8, and the water pump 3 is mounted directly above the cleaning roller 1. The output end of the motor 2 is connected to the cleaning roller 1. The outlet of the water pump 3 is connected to a long pipe 4, and the outlet of the long pipe 4 is connected to a short pipe 41. The short pipe 41 and the long pipe 4 are connected by a corrugated pipe. A spring piece 42 is connected between the short pipe 41 and the long pipe 4. The bottom of the short pipe 41 is connected to a water collection pipe 5.

[0022] Please see Figure 3 , Figure 4 and Figure 5 The cleaning roller 1 can maintain and clean the bar screen 8. The motor 2 can provide driving force for the cleaning roller 1. The water pump 3 can clean the cleaning roller 1 through the water source. The bar screen 8 is a common bar screen machine in the prior art. The short pipe 41 can change its angle outside the long pipe 4. The spring 42 can drive the short pipe 41 to return to its original position after the movement is completed.

[0023] The lower end of the long tube 4 is equipped with a bending mechanism 6. The bending mechanism 6 includes a slotted block 61 and a protrusion 65. The slotted block 61 is connected to the long tube 4. A sliding block 63 is slidably connected to the inner groove of the slotted block 61. A spring 62 is connected between the sliding block 63 and the slotted block 61. An I-beam 64 is connected to the bottom of the sliding block 63, and one end of the I-beam 64 is connected to the spring piece 42. There are two sets of protrusions 65, which are respectively assembled on the outside of the water pump 3. A transmission belt 7 is assembled between the protrusions 65 and the cleaning roller 1.

[0024] The slotted block 61 has a slot on its inner side, which can guide the sliding block 63 to move linearly. The spring 62 can drive the sliding block 63 to return to its original position after the movement is completed. The protrusion 65 can be driven by the transmission belt 7, which in turn drives the I-beam 64 and the short pipe 41 to rotate. At the same time, the end of the I-beam 64 connected to the short pipe 41 is elastic and can be bent to avoid the I-beam 64 and the short pipe 41 from colliding.

[0025] A bristle sleeve 11 is fitted onto the outside of the cleaning roller 1, and bristles are evenly distributed on the outside of the bristle sleeve 11. The bristle sleeve 11 is connected to the cleaning roller 1 by a pin. The bristle sleeve 11 can be disassembled from the outside of the cleaning roller 1, thereby facilitating the maintenance and repair of the cleaning roller 1.

[0026] The motor 2 is externally mounted with a first base 21, and the water pump 3 is mounted with a second base 31 at its bottom. The first base 21 facilitates the support and fixation of the motor 2, and the second base 31 facilitates the support and fixation of the water pump 3.

[0027] Both sides of the transmission belt 7 are equipped with pulleys 71. The two pulleys 71 are connected to the cleaning roller 1 and the protrusion 65 respectively. The pulleys 71 can improve the transmission effect of the transmission belt 7 between the cleaning roller 1 and the protrusion 65.

[0028] The end of the I-beam 64 near the protrusion 65 is polished and the outside is rounded. The polishing and rounding of the I-beam 64 facilitates the movement of the protrusion 65 when it rotates.

[0029] The water collection pipe 5 includes a horizontal pipe with nozzles evenly distributed at the bottom. The nozzles are located to the upper right of the cleaning roller 1. The water collection pipe 5 can spray water through multiple sets of nozzles to improve the cleaning effect on the cleaning roller 1.

[0030] This solution first assembles the cleaning roller 1 to the discharge port end of the bar screen device 8 using bolts, etc. When in use, the motor 2 is started to drive the cleaning roller 1 to rotate, thereby driving the screen residue that cannot be discharged normally inside the bar screen device 8 to be discharged into the screw conveyor outside the cleaning roller 1.

[0031] Connect the external water source to the water pump 3, start the water pump 3 to draw in water and discharge it through the long pipe 4 and the water collection pipe 5 to treat the outside of the cleaning roller 1 and prevent the screenings from getting stuck on the outside of the cleaning roller 1. At the same time, the cleaning roller 1 drives the protrusion 65 to rotate through the transmission belt 7, which drives the I-plate 64 to move, and finally drives the short pipe 41 to change the angle, thereby improving the treatment effect of the short pipe 41 on the cleaning roller 1.

[0032] By adding cleaning roller 1 and water pump 3, the screenings in the gaps of the bar screen 8 are pushed and processed when the bar screen 8 is working, so as to prevent the screenings from being discharged into the sewage tank again after moving with the bar screen 8, which would cause the device to become clogged and reduce its service life. At the same time, by adding bending mechanism 6, the spray angle of water collection pipe 5 is automatically changed when water pump 3 cleans the cleaning roller 1, thereby improving the cleaning range and cleaning effect, and completely preventing the screenings from getting stuck inside the cleaning roller 1.
