Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a multi-stage screening apparatus for a multi-stage screening apparatus equipped with a high-pressure washer for improving the function of removing fine contaminants,

The present invention relates to a multi-stage screen device installed in an impurity collecting processor for separating various impurities from manure, livestock wastewater and the like from a filtrate to remove fine contaminants such as seeds and animal hair, A cleaning means for cleaning the screen by spraying washing water or compressed air to the surface of the cylindrical screen, wherein the cleaning means is connected to the cleaning coil hose and the washing water is sprayed through a short length spraying body reciprocating along the longitudinal direction of the screen, And the compressed air is injected alternately, the cleaning function of the cylindrical screen is greatly improved by increasing the injection pressure of the washing water and the compressed air, and the overflow due to the extremely clogging phenomenon inside the screen due to the fine contaminants By preventing, more than the removal of micro-contaminants With a pressure washer for fine impurities removal function so as to improve a conversation mounted impurities synthesis process relates to a multi-stage unit for screening machines.

In recent years, due to the increase in the urban population and the increase in the size of the livestock farmers, a large amount of waste water, wastewater, manure, and livestock wastewater are generated, and due to such waste water, domestic wastewater, manure, Contamination of groundwater, rivers and coastal waters is not only serious but also has a bad influence on the formation of a comfortable living environment due to odor generated from wastewater, domestic sewage, manure, and livestock wastewater.

In the case of manure and livestock wastewater, separate purification facilities are provided for each area and are managed and treated at the governmental level. However, in the case of livestock wastewater, the concentration of suspended solids (SS) is 20,000 ~ 25,000 ppm, So as to treat the manure and the livestock wastewater more efficiently, various kinds of impurities are removed from the collected manure and livestock wastewater, and the resulting liquid is filtered into a liquid filtrate having a low suspended concentration. Then, It is sent to the final purification facility to be processed.

In order to separate manure or livestock wastewater into filtrate and impurities as described above, manure or livestock wastewater is introduced into the inside of the processor body, and the filtrate generated in the primary impurity processing by the rotary screen and the screw press is stored in the filtrate reservoir And the filtrate stored in the filtrate storage tank is pumped to a cyclone connected to a screen device and a centrifuge to remove fine contaminants such as seeds, animal hair, and sebaceous components contained in the filtrate, (Hereinafter, referred to as " patent No. 10-0880270 ") by the present applicant, which is supplied to the final purification facility through the filtrate discharge tank.

The screen device for separating fine contaminants such as seed components or animal fur from a cyclone into a filtrate in the impregnated composite processing device of the present application filed by the present applicant includes a device housing in which a filtrate discharge duct is provided at a lower portion thereof, And a cylindrical screen which is rotatably installed in the interior of the cylindrical screen. The discharge port of the fine impurity is formed on the front side of the apparatus housing and the cylindrical screen, and a fine impurity conveying screw is installed in the cylindrical screen , The inlet tube of the contaminant extending from the cyclone extends through the rear side wall portion of the device housing and extends to the interior of the cylindrical screen.

In addition, a spray pipe for spraying wash water toward the surface of the screen is installed as an upper surface of the cylindrical screen as cleaning means for the screen. The cylindrical screen is disclosed in the prior application (Registration No. 10-0928559) A first screen for first removal of fine contaminants and a second screen disposed outside of the first screen for performing secondary removal of fine contaminants, And the injection pipe is located on the upper side of the second screen.

Since a plurality of spray nozzles are installed at the injection pipe at regular intervals, the washing water can be periodically sprayed onto the surface of the screen in the process of separating the fine contaminants from the filtrate by rotating the cylindrical screen. As a result, It is possible to improve the function of removing the fine contaminants by the screen device by preventing the phenomenon of causing the remarkable deterioration of the contaminant removing function such as the overflow phenomenon caused by the closing of the water dropping through the fine contaminants such as the seeds or the bristles of the animal .

However, when the injection pipe as described above is applied as a cleaning means of a screen, a large number of injection nozzles are installed at a predetermined interval on the lower side of the injection pipe having the same length as the screen so that the washing water is uniformly sprayed to the surface side of the screen , There is a problem that it is difficult to sufficiently secure the jetting pressure of the washing water as the washing water is simultaneously injected through a large number of jetting nozzles when jetting the washing water using the washing water pump.

In other words, since the fixed injection pipe, which is elongated along the longitudinal direction of the screen, is applied as the cleaning means, when the washing water is pumped into the injection pipe through the injection line connected to the washing water pump, The pressure is dispersed through dozens of injection nozzles installed along the longitudinal direction of the injection pipe so that the pressure of the washing water sprayed from each injection nozzle drops to a level significantly lower than the inlet side pressure of the injection pipe.

As described above, when the jetting pressure of the washing water sprayed from each spraying nozzle is lowered, it is difficult to smoothly perform a washing operation for dropping fine contaminants such as seeds or bristles embedded in the water dripping holes of the screen into the screen, To avoid this situation, the pump motor of the wash water pump must be rotated at a high speed or the wash water pump itself must be replaced by an expensive high pressure pump.

However, the above-mentioned countermeasures not only cause waste of unnecessary washing water, but also increase the processing load of the filtrate due to the input of a large amount of washing water. Also, when the washing water pump is overloaded, It is not preferable to use an expensive high-pressure pump because it increases the equipment cost of the impregnated comprehensive processor including the screen device, which is an economical burden to the purchaser.

In addition to this, by applying a method of alternately spraying the washing water and the compressed air during the screen washing operation, it is possible to wash the washing water to the one-stage screen disposed inside the two-stage screen while minimizing the waste of the washing water and the processing load of the filtrate Although the efficiency of the cleaning operation can be greatly improved, it is also very difficult to apply compressed air to the cleaning operation of the screen due to the conventional unreasonable structure using the fixed injection pipe and the low injection pressure as described above.
