Embodiment 1
[0020] Such as figure 1 As shown, a variable pressure system for sludge conveying and press filter feeding includes a filter press 1 and a sludge tank 2. The feed inlet of the filter press 1 is provided with a feed pipe 11, and the feed pipe 11 is far away from the press. One end of the filter machine 1 is provided with a sludge delivery pump 12, and the feed pipe 11 is provided with a feed valve and an instrument near the filter press 1. The sludge tank 2 is provided with a pressure-regulating bag 3, and the outer wall of the sludge tank 2 is provided with a pressure-regulating valve 21 and an exhaust valve 22. The lower end of the sludge tank 2 is vertically provided with a discharge pipe 23, and the discharge The upper end of the pipe 23 communicates with the inside of the pressure regulating bag 3, and the lower end of the discharge pipe 23 communicates vertically with the feed pipe 11. The discharge pipe 23 is provided with a first valve 24, and the top of the first valve...

The invention discloses a variable-pressure system for sludge conveying and filter-pressing feeding. The variable-pressure system comprises a filter press and a sludge tank, a feeding pipe is arranged at a feeding hole of the filter press, and a sludge conveying pump is arranged at one end, far away from the filter press, of the feeding pipe; a pressure regulating bag is arranged in the sludge tank, a pressure regulating valve is arranged on the outer side wall of the sludge tank, a discharging pipe is vertically arranged at the lower end of the sludge tank, the upper end of the discharging pipe is communicated with the interior of the pressure regulating bag, and the lower end of the discharging pipe is communicated with the feeding pipe; and a first valve is arranged on the discharging pipe. The sludge tank and the pressure regulating inner bag are adopted, after feeding of the filter press is reduced, redundant sludge can be directly stored in the pressure regulating bag for caching, the stored sludge is conveyed into the filter press after the sludge conveying pump stops working, continuous feeding of the filter press is achieved, abrasion to the sludge conveying pump is reduced, and the equipment maintenance cost is reduced.
Description
technical field [0001] The invention relates to the field of sludge treatment equipment, in particular to a variable pressure system for sludge conveying and filter press feed. Background technique [0002] At present, the amount of sludge produced in the sand and gravel industry and high-turbidity wastewater is large, and the distance for the sludge to be transported to the filter press system is relatively long. Generally, the sludge is transported to the intermediate tank by the sludge pump, and then sent to the filter press by the filter feed pump for sludge dehydration. During this process, the sludge needs to be lifted repeatedly, which consumes a lot of energy, and because of the large amount of sediment in the conveying medium, the wear and tear on the lifting equipment is large, and the maintenance cost of the lifting equipment is high. Contents of the invention [0003] The purpose of the present invention is to provide a variable pressure system for sludge conv...
