Description

Multi-stage screen device for the overall processing system of the complexes equipped with the high pressure cleaner to improve the fine dust removal function

The present invention relates to a multi-stage screen device which is installed in a complex integrated processor for separating various contaminants from filtrate and manure from filtrate and removes fine contaminants such as seeds and animal hairs, and which rotates inside the device housing of the screen device. Washing means is installed to spray the washing water or compressed air to the surface of the cylindrical screen to perform the washing operation of the screen, but the washing water through the short length of the reciprocating movement in the longitudinal direction of the screen in connection with the expansion coil hose And by applying a high pressure washer that alternately injects compressed air, thereby increasing the injection pressure of the washing water and compressed air, greatly improving the washing function of the cylindrical screen, and overflow due to severe clogging inside the screen by fine contaminants. Prevents the removal of fine 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.

Recently, according to the increase of urban population and the enlargement of livestock farms, a large amount of sewage, wastewater, domestic sewage, or manure or livestock wastewater is generated. Contamination of groundwater, rivers and coastal waters is becoming more serious and adversely affects the creation of a pleasant living environment due to odors generated from wastewater, wastewater, domestic sewage, or manure or livestock wastewater.

In particular, in the case of manure or livestock wastewater, a separate purification facility is provided for each region and managed and managed at the government level. However, in the case of livestock wastewater, the concentration of suspended solids (SS) is 20,000 ~ 25,000ppm. There was a problem in that the operation of the overload was applied, and thus, various wastes from the collected manure and livestock wastewater were removed and formed into a liquid filtrate with a low concentration of suspended solids in order to treat the manure and livestock wastewater more efficiently. It is sent to the final purification facility for disposal.

As described above, to separate the manure or livestock wastewater into the filtrate and contaminants, to put the manure or livestock wastewater into the interior of the processor body, and stores the filtrate generated in the process of processing the first contaminants by rotary screen and screw press in the filtrate storage tank And pumping the filtrate stored in the filtrate into the cyclone connected to the screen device and the centrifuge to remove the fine contaminants such as seeds, animal hairs, and sesame in the filtrate, and then treating the filtrate as described above. It is known that an application for the application of a composite material to a final purification facility through the filtrate discharge tank has been filed and registered by the present applicant (registration number: 10-0880270).

Applicant's prior application to the complex processing apparatus of the present application, the screen device for separating the fine components such as the seed component or animal hair from the cyclone with the filtrate is a device housing, the filtrate discharge duct is provided at the bottom, It comprises a cylindrical screen installed to rotate by the power of the drive motor therein, the outlet of the micro-clenches are formed on the front side of the device housing and the cylindrical screen, the screw screw is installed in the interior of the cylindrical screen The input tube of the contaminant extending from the cyclone extends through the rear wall portion of the device housing and extends to the inside of the cylindrical screen.

In addition, the upper side of the cylindrical screen is a spray pipe for spraying the washing water toward the surface of the screen is installed as the washing means for the screen, the cylindrical screen is the first application and patent registration by the present applicant (Registration No .: 10-0928559) As in the multi-stage screen device, the first screen for the primary removal of fine contaminants, and the second screen disposed outside of the first screen to perform the secondary removal of the fine contaminants, in this case The injection pipe is located on the upper side of the second screen.

As a plurality of injection nozzles are installed in the injection pipe at regular intervals, the cylindrical screen is rotated to periodically spray the washing water to the surface of the screen in the process of separating the fine contaminants from the filtrate. Improves the ability to remove fine contaminants by the screening device by preventing situations that cause drastic deterioration of the debris removal function, such as overflow caused when water drainage is blocked by fine contaminants such as seeds or animal hair. To make it work.

However, when the above-mentioned injection pipe is applied as the cleaning means of the screen, by installing a large number of injection nozzles at regular intervals on the lower side of the injection pipe having the same length as the screen so that the washing water is evenly sprayed to the surface side of the screen. When spraying the washing water using the washing water pump, the washing water is simultaneously sprayed through a large number of spray nozzles, so it is difficult to secure the spray pressure of the washing water sufficiently.

In other words, since the fixed spray pipe installed in the longitudinal direction of the screen is applied as the washing means, when the washing water is pumped into the spray pipe through the injection line connected to the washing water pump, Pressure is distributed 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 significantly lower level than the inlet pressure of the injection pipe.

As described above, when the injection pressure of the washing water sprayed from each injection nozzle is lowered, it is difficult to perform the washing operation to drop fine contaminants such as seeds or animal hairs stuck in the water drain hole of the screen into the screen smoothly. In order to prevent this situation, the pump motor of the wash water pump should be rotated at high speed, or the wash water pump itself should be replaced with an expensive high pressure pump.

However, the above countermeasures not only cause unnecessary waste of washing water, but also increase the processing load of the filtrate according to the input of a large amount of washing water, and the failure or malfunction of the washing device due to the overload of the washing water pump is caused. In addition to the high risk, the application of expensive high-pressure pump is not preferable because it increases the cost of equipment of the contaminant processing system including the screen device, which puts an economic burden on the buyer.

In addition, by applying a method of alternately spraying the washing water and compressed air during the cleaning of the screen, it is possible to clean up to the first stage screen disposed inside the second stage while minimizing waste of washing water and 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 of the screen due to the conventional irrational structure using the fixed injection pipe and the low injection pressure as described above.

The present invention has been made to solve the above problems of the prior application, and alternately spraying the washing water and compressed air through a short length injector reciprocating along the longitudinal direction of the cylindrical screen in the state connected to the expansion coil hose By applying high pressure washer to the screen device, the spray pressure of washing water and compressed air is greatly increased to prevent extreme clogging of the screen due to fine contaminants and consequent overflow, and to clean the screen and remove fine contaminants. In addition to significantly improving the pressure, the same injection pressure is used to reduce the amount of washing water and compressed air, reduce the processing load of the filtrate, and prevent the failure or malfunction of the washing device due to the overload of the washing water pump and air compressor. More economical and reasonable screen cleaning The ever possible to remove the fine impurities effectively work as a technical problem of the first.

Along with (44) is carried out in a manner of spraying the washing water and compressed air to the surface side of the second screen 30 while moving in the front and rear directions (left and right directions on the drawing), after the washing operation according to the spray of the washing water Compressed air is injected into the

While moving the movable injector 45 having a short length as described above along the longitudinal direction of the screen on the upper side of the second screen 30, in this process the washing water and compressed air from the movable injector 45 By alternately spraying toward the surface of the two screens 30, by greatly increasing the injection pressure of the washing water and the compressed air can greatly improve the cleaning function of the screen.

In other words, in the present invention, since the movable injection body 45, whose length is very short compared with the conventional fixed injection pipe, is applied as the washing means, the expansion coil hose from the washing water pump 50 and the air compressor 51 is used. 46) the pressures of the washing water and the compressed air introduced into the inlet of the spraying body 45 are dispersed only through a very small number of spray nozzles, so that the pressure of the washing water and the compressed air sprayed from the respective spray nozzles is injected. It is maintained at about the same level as the inlet pressure of (45).

As described above, since the injection pressure of the washing water and the compressed air injected from each injection nozzle can be greatly increased, and the washing operation over the entire length of the screen is possible according to the movement of the injection body 45, under the same injection pressure conditions The amount of washing water and compressed air can be reduced, and the processing load of the filtrate can be reduced, and the washing water and compressed air can be prevented from failure or malfunction of the washing apparatus due to the overload of the washing water pump 50 and the air compressor 51. By applying alternate spraying methods, screen cleaning can be performed in a much more economical and rational way than conventional stationary spraying pipes.

In addition, while the high-pressure cleaner 40 is embedded in the washing machine casing (40a), the modular washing structure that can be detachably assembled with the washing machine casing (40a) on the upper surface of the device housing (16) of the screen device (10). By providing a, easy installation, maintenance and replacement of the high pressure washer 40 is possible, such that the flexible coil hose 46, which is a flexible material, is stably stretched along the hose support 46a without sagging downward. By doing so, it is possible to prevent damage or short-circuit of the expansion coil hose 46 in advance and to operate the high pressure cleaner 40 more safely and accurately.

In addition, in the present invention, the transfer sprocket 43 and the reciprocating transfer chain 44 are applied as a means for moving the injection body 45. In addition, the transfer pulley and the reciprocating transfer belt may also be applied. To guide the movement of the injector 45 inside the wall of the device housing 16 so that the reciprocating belt can be drooped to the lower side and the reciprocating belt can be prevented from shaking by the injection force of the washing water and the compressed air. It is advantageous to install a guide rail or the like parallel to the second screen 30.

In addition to the application of the high pressure cleaner 40 as described above, as described in the foregoing description based on FIG. 2, two dewatering screens composed of the first screen 20 and the second screen 30 are different from each other. A rotating roller brush 48 which rotates in the axial direction in contact with the surface of the dewatering screen 21 of the first screen 20 between the

respective screens

20 and 30 while being rotated at a speed. You can also install).

As shown in FIGS. 2 and 7, the roller brush 48 has a front wall 32 and a rear wall 39 of the second screen 30 with bearing joints 48a at both ends thereof. Rotating shaft 49a which is installed in a direction parallel to the screen, and radially spaced apart at close intervals along the longitudinal direction of the rotating shaft 49a to closely contact the surface of the dewatering screen 21 of the first screen 20. It consists of a washing brush (49).

As described above, the roller brush 48 provided with the cleaning brush 49 along the rotating shaft 49a has a function of removing general contaminants to scrape the surface of the dewatering screen 21 of the first screen 20, and to clean the respective brushes. The sole 49 can easily penetrate into the dehydration passage (dehydration hole or dewatering slit) of the dewatering screen 21 in the process of rotating together with the rotary shaft 49a, thereby being inserted into the dehydration passage of the dewatering screen 21. Contaminants can also be effectively eliminated.

Accordingly, when the roller brush 48 is used in combination with the high pressure cleaner 40 to perform the screen cleaning operation, dehydration is formed on the dehydration screens 21 and 31 of the first screen 20 and the second screen 30. Not only can the ball 21a or the dehydration slit 31a be blocked by the fine contaminant fundamentally, but also prevent the local abrasion of the cleaning brush 49, thereby replacing the roller brush 48. It can be extended to the maximum, thereby ensuring the continuous and stable operation of the multi-stage screen device 10 will be able to further maximize the removal function of fine contaminants.

Finally, the above descriptions relate to the two-stage screen device 10 by the first screen 20 and the second screen 30, but inside, outside or the second screen 30 of the first screen 20. In addition, a cylindrical screen may be additionally installed on the outside to provide a three-stage screen device. In this case, the roller brush 48 may be disposed between the outer screen and the center screen and between the center screen and the inner screen. Each will be installed.

In addition, when the processing load of the fine contaminants is relatively low, it is also possible to install only one single screen selected from the first screen 20 or the second screen 30 inside the device housing 16. The design change is not only obvious to those skilled in the art, but it is to be understood that the present invention is naturally included within the scope of the technical idea to be pursued.

The present invention can be used as a multi-stage screen device that can be installed in a complex comprehensive processing for separating various contaminants from the manure or livestock waste water and the filtrate to remove fine contaminants such as seeds and animal hair.
