Description

Technical Field

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

[0002] With the acceleration of urbanization and industrialization, sewage discharge has increased dramatically. Urban domestic sewage contains a large amount of household garbage, textile fibers and other debris, while industrial wastewater contains various waste residues and fibers. If these solid impurities enter the sewage treatment system directly without treatment, they will seriously affect subsequent treatment stages. In the sewage treatment process, it is necessary to separate the impurities from the water to protect the normal operation of subsequent treatment equipment. Bar screens can intercept solid particles and suspended solids in sewage through bar screens, achieving the purpose of preliminary water purification.

[0003] If the wastewater contains a large amount of fibrous, ribbon-like, or highly viscous substances, such as fabric fibers, hair, plastic film, sludge, etc., these substances can easily become entangled in the rake teeth, bars, or transmission components of the bar screen, causing blockage. Once blocked, it will not only reduce the cleaning efficiency of the bar screen, but may also affect the normal operation of the equipment, or even cause damage to the equipment.

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

[0005] The purpose of this utility model is to provide a bar screen for sewage treatment, which solves the problems mentioned in the background art.

The blocking bracket is fixedly connected to one side of the fixed protective bracket, the fixing ring is fixedly connected to one side of the fixed protective bracket, and the rotating rubber strip is movably connected to the inner side of the fixing ring.

[0009] Preferably, the threaded drive surface cleaning assembly includes a drive bracket, a free-spinning threaded rod, a forward and reverse motor, a fixed support rod, a bracket surface cleaning claw, and a lower fixed bracket. The drive bracket is fixedly connected to the upper side of the fixed protective bracket, and the free-spinning threaded rod is rotatably connected to the inner side of the drive bracket. The free-spinning threaded rod is fixedly connected to the forward and reverse motor on one side. The fixed support rod is threadedly connected to the surface of the free-spinning threaded rod, and the bracket surface cleaning claw is fixedly connected to the lower end of the fixed support rod. The lower end of the fixed support rod is slidably connected to the lower fixed bracket.

[0010] Preferably, the rubber strip shaft drive assembly includes a sleeve-type rotating shaft, a sleeve belt, and a fixed motor. The rotating rubber strip passes through the fixed protective bracket and is fixedly connected to the inner sleeve-type rotating shaft. The sleeve belt is sleeved on the surface of the sleeve-type rotating shaft, and the fixed motor is sleeved on the other end of the sleeve belt.

[0011] Preferably, the floating object temporary storage assembly includes a detachable storage box and a dismantling handle.

The filter screen is fixedly connected to one side of the fixed plug, and the adsorption screen is plugged into the inner side of the filter screen.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] With the sewage floating debris treatment and cleaning mechanism in place, during use, the barrier brackets are uniformly and fixedly connected to the front end of the fixed protection bracket in a ring shape. The rotating rubber strips are installed between the corresponding gaps of the barrier brackets, and the rotating rubber strips are installed at the rear end of the barrier brackets to prevent large floating debris from directly wrapping around the surface of the rotating rubber strips and causing blockage. The forward and reverse motor drives the idle threaded rod to rotate, causing the fixed support rod threaded to move left and right. The bracket surface cleaning claws installed at the lower end of the fixed support rods adhere to the barrier brackets, cleaning the floating debris accumulated on the surface of the barrier brackets. When the fixed support rod drives the lower end of the bracket surface cleaning claws to the left side of the fixed protection bracket, the floating debris accumulated on the surface can be collected into the interior of the removable storage box through a pipe at one end, and then disassembled and cleaned by the disassembly handle.
