Problems solved by technology
The backwashing device in the filter tank is driven by a trolley to move the mud suction pipe along the plane of the blanket-like braid to suck the sludge. In practical applications, the following problems will exist due to the technical processing accuracy: First, the mud suction branch pipe is due to the inflow of water. The uncertainty of sundries is prone to blockage, which affects the effect of backwashing; secondly, after the blockage occurs, the entire suction branch pipe must be removed to observe and deal with the problem of the suction branch pipe, which affects the maintenance efficiency

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0018] figure 1 It is a schematic front view of the filter backwashing system of the present invention installed in the filter.
[0019] figure 2 It is a schematic side view of the filter backwashing system of the present invention installed in the filter.
[0020] Such as figure 1 and figure 2 As shown, the filter backwashing system includes: driving track 13, driving 1, mud discharge pipeline 2, dredging pump 3, dredging motor (not shown in the figure), dredging main pipe 4 and ten dredging branch devices .
[0021] The driving track 13 is arranged above the filter tank that needs to be backwashed. The driving vehicle 1 moves on the driving rail 13 to drive the whole filter tank backwashing system to move. The mud discharge pipe 2 is arranged on the crane 1 and is connected with the mud suction pump 3 for sucking up the sludge from t...

The invention provides a backwashing system for a filter tank. The backwashing system is characterized in that the system has a main sludge sucking pipe and at least one sludge sucking branch apparatus and each sludge sucking branch apparatus comprises a flexible sludge sucking pipe, a branch sludge sucking pipe, a branch sludge sucking pipe support and a sludge sucking support fixed part, wherein the flexible sludge sucking pipe is connected with the main sludge sucking pipe, the branch sludge sucking pipe is connected with the flexible sludge sucking pipe and fixed on the branch sludge sucking pipe support, the branch sludge sucking pipe support is hinged with the outer wall of the main sludge sucking pipe, one end of the sludge sucking support fixed part is in detachable fixed connection with the outer wall of the main sludge sucking pipe, and the other end of the sludge sucking support fixed part is in fixed connection with the branch sludge sucking pipe support. The backwashing system has the following advantages: when the backwashing system is in need of maintenance, it only needs to dismount the detachable sludge sucking support fixed part from the outer wall of the main sludge sucking pipe so as to allow the branch sludge sucking pipe support to drive the branch sludge sucking pipe to rotate and to enable the branch sludge sucking pipe to be disconnected with a filter cloth apparatus in the filter tank, so observation and maintenance of the part of the branch sludge sucking pipe are facilitated, and maintenance time and maintenance difficulty are reduced.
Description
technical field [0001] The invention relates to the technical field of water treatment, in particular to a backwashing system for cleaning filter components in a filter tank. Background technique [0002] After the filter has been used for a certain period of time, it is necessary to periodically backwash the filter layer. One is to discharge the impurities and dirt in the filter layer with water to clean the filter layer; the other is to reduce the cost of filtration operations in water treatment. resistance. The traditional mobile flushing hood filter has been widely popular because of its advantages of low cost, less valves, and convenient flushing. However, in practice, it is found that during the use of the backwashing device, due to the instability of the size and composition of impurities and dirt in the water, it is easy to block the mud suction branch pipe, which directly affects the backwashing effect. The backwashing device usually used is directly fixed on the ...
