Problems solved by technology

The evacuation of compressed air in each filtration cycle makes the system need to continuously turn on the air compressor to replenish compressed air, and the system consumes a lot of energy
The compressed air evacuated every cycle contains a large amount of VOC, which pollutes the surrounding environment
High-pressure compressed air needs to be supplemented for each feeding cycle of the system. The operation of high-power air compressors and the discharge of high-pressure air will generate a certain amount of noise pollution.
(4) There are a lot of equipment and the failure rate is high
There are a lot of equipment and automatic valves in this feeding method, and the discharge of high-pressure air makes the air compressor need to be started and stopped continuously, resulting in a high failure rate of equipment

Embodiment 1

[0036] Such as figure 1 As shown, the feeding system for the filter of the present embodiment includes a controller, an air pressure assembly 1, a pumping assembly 2 and a feed valve 3, and the pumping assembly 2, the air pressure assembly 1, the feed valve 3 and the filter 4 are sequentially connected. Among them, the pneumatic assembly 1 relies on compressed air to press the material into the filter 4 when the filter 4 is fed; the pumping assembly 2 pumps the material into the air pressure assembly 1 when the air pressure assembly 1 stores the material; the feed valve 3 is used to control the material To switch on and off the delivery to the filter 4, the feed valve 3 is opened when the air pressure component 1 presses the material to the filter 4, so as to ensure the smooth progress of the filter 4 feeding. In this embodiment, when the internal pressure of the pneumatic component 1 drops to the same pressure as the feed pressure of the filter 4, the controller receives the...

Embodiment 2

[0052] figure 2 It shows another embodiment of the feeding system for a filter according to the present invention. This embodiment is basically the same as the previous embodiment, except that the air pressure assembly 1 of this embodiment includes an air pressure tank 14 . The pressure tank 14 is preset with compressed air and materials before the filter 4 feeds. In this embodiment, the capacity of the air pressure tank 14 is equal to 3 times of the total feed volume of the filter 4, which enables the air pressure tank 14 to ensure sufficient pre-set space for compressed air and materials while satisfying sufficient driving force for the materials. At the same time, the pressure P of the air tank 14 3 Feed pressure P for the filter 2 1~2 times of P 2 3 2 When , the air pressure component 1 and the pumping component 2 provide materials to the filter 4; when 1.5P 2 ≤P 3 ≤2P 2 , the air pressure assembly 1 provides materials to the filter 4.

Embodiment 3

[0056] image 3 Show another embodiment of the feeding system for a filter of the present invention, this embodiment is basically the same as Embodiment 1, the difference is that the feed pump 22 of this embodiment is at least set to two, a plurality of feed pumps 22 are arranged in parallel, and the setting of multiple sets of feed pumps 22 effectively increases the feed speed, and ensures the smooth progress of feed when one feed pump 22 fails, and its reliability is high. There are at least two filters 4, and multiple filters 4 are arranged in parallel. The number of feed valves 3 and pressure sensors 6 is the same as the number of filters 4, and the feed valve 3 and pressure sensors 6 are the same as the number of filters 4. One to one corresponding setting. The feed system for the filter is equipped with multiple filters 4 at the same time, which effectively improves the feed efficiency and utilization of the feed system.

Abstract

The invention provides a feeding system and method used for a filter. The system comprises a controller, an atmosphere pressure assembly, a pumping assembly and a feeding valve, wherein when the atmosphere pressure assembly pressure decreases to the filter feeding pressure, a received atmosphere pressure assembly pressure detection value and a set threshold value are compared by the controller, and when the pressure detection value is smaller than the set threshold value, the pumping assembly pumps material to the filter and the atmosphere pressure assembly. The method comprises the steps thatthe material is pumped into the atmosphere pressure assembly, when the material of the atmosphere pressure assembly reaches a set liquid level value, the material in the atmosphere pressure assemblyis pressed into the filter; when the internal pressure of the atmosphere pressure assembly decreases to the filter feeding pressure, if the internal pressure of the atmosphere pressure assembly is smaller than the set threshold value, the feeding speed of the pumping assembly is improved, the pumping assembly pumps the material into the filter and the atmosphere pressure assembly, if the internalpressure of the atmosphere pressure assembly is larger than or equal to the set pressure value, the filter feeding amount is met, the feeding value is closed, the filter enters an extrusion working procedure, and the pumping assembly continues pumping the material to the atmosphere pressure assembly.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a feeding system and a feeding method for a filter. Background technique [0002] High-pressure filtration is a filtration method that applies mechanical force to one side of the filter medium to achieve solid-liquid separation of sludge (water). The traditional filter feeding method uses a pump to feed, but the delivery capacity of the pump is difficult to choose. When the pump is selected according to the maximum feed rate, when the feed rate slows down in the later stage, the feed flow rate will be much smaller than the pump flow rate, resulting in waste; when the pump is selected according to the small flow rate, the feed time will be prolonged, which reduces the high pressure Filtration processing power. At the same time, the head of the pump (that is, the filtering driving force) is constantly changing due to the structure of the pump and the characteristics of the pipelin...
