Description

Horizontal screen for water and sewage treatment {HORIZONTAL SCREEN}

The present invention removes foreign substances that have joined the water and sewage from the waterway to prevent foreign substances from depositing and decaying in the water tank, and completely protects the related water treatment facilities for water treatment by preventing the discoloration of the pipes of the pump and the digester. As a horizontal screen device for water and sewage treatment to prevent a decrease in treatment flow rate due to a decrease in flow rate, the conventional screen device vertically sets a flat-bar to allow water and sewage to flow out at intervals between bars. -The foreign material on the bar is a back-inlet screen that protrudes from the back of the flat bar between intervals and is caught by the rake blades driven by the chain drive, withdrawn upwards and flows down along the flat-bar upper hopper. The clean tops the debris with the rake blade running between the flat bars during the debris removal operation. Even though the rake blade passes through the gap between the bars, some of the foreign substances are caught between the bars. During winter, the blades do not run freely due to freezing of foreign substances and water between the screen and the screen. Even if the vehicle is driven, foreign matter and ice are not treated, and the case is attached to the screen-bar, which causes work efficiency to be deteriorated, and the screen-bar is warped, resulting in repair and cases. There are problems such as overloading of the motor due to freezing and poor treatment of sedimentation and deposition of foreign matter on the bottom of the channel.

The present invention is a horizontal screen device for water and sewage treatment. The right end of the screen is formed with a horizontal angle of 35 degrees in the direction of flowing water, and the flow direction of flowing water flows along the screen angle before the inflow water passes through the screen. The small amount of foreign matter is applied to prevent the decrease of the processing flow rate due to the flow rate decrease, and the load on the screen-bar caused by the foreign matter is less, which prevents the bending of the screen-bar caused by the load and the rear of the right end of the screen. The belt conveyor is placed in contact with each other so that the flow of water flows along the screen direction, so that foreign matters contained in the flowing water naturally flow to the belt conveyor and are collected, and the foreign substances collected in the water are drawn upwards by continuous operation of the belt conveyor. Discharged through the hopper into the debris reservoir and also screen-bar spacing. In order to handle the foreign matters, the rake device is operated to transfer the foreign matters hanging on the screen-bar to the belt conveyor.

The horizontal screen for water and sewage treatment moves the rake device to the left and right, and transports foreign substances. Therefore, the rake works by freezing foreign matter and water between the screen-bars above the water level of the screen that occurs during the winter in the conventional vertical screen. If the rake is excessively operated and the rake is not excessively driven, the screen bar may be warped, and the foreign matters frozen on the screen bar may cause the processing to be interrupted, and the problem of inefficient work and the problem of the conventional screen-bar As it solves by complementary or new technology development, the flow of the flowing water is good and the safety is very good.

This paper proposes a screen device (1,2,3,4,5,32,36,40) that blocks and collects foreign substances in water and sewage waterways (13.14,15,16). , 17,18,19.20.21.22.23.24, 25, 26, 27, 30, 32, 35, 36, 37, 38, 39) Inclination hopper by drawing foreign substances collected in the water above the surface (11) consists of a belt conveyor device (6, 7, 8, 9, 10, 29, 31 33, 40) discharged to the foreign matter storage tank (12), which is a more detailed form of a stainless steel plate- Form a horizontal angle of 35 degrees with the right end of the horizontal bar in the flowing direction, and make a screen-bar (1) by v-cutting to the center point at the left and right ends at the rear of the flat-bar and toward the center point. After the rubber plate 5 is attached to the outer surface of the left wall plate 3 of the screen where the bolt holes are formed on the lower, left, and right sides of the screen, the inner surface of the water channel left wall 34 is formed. Insert into the anchor bolt (4), then tighten the tightening nut, tighten the screen unit (1,2,3,4,5,32,36) to the water channel on the left side wall (34), the triangular vertical support (2) The bolt hole formed on the bottom fixing plate is inserted into the anchor bolt 41 formed on the bottom of the channel, tightened with a fastening nut to be fixed to the bottom of the channel, and made of stainless steel, and made of stainless steel frame (6.31) Belt conveyor left frame (6) with bolt holes formed on the side and the right side of the screen right end of the screen so that the connecting piece 36 is in contact with each other, and the bolt 32 is inserted, tightened by tightening knots, and fixed to the belt conveyor frame (6.31) After contacting the base plate 33 formed in the bottom portion in close contact with the concrete surface of the water channel, and then put the anchor bolt 29 in the bolt hole formed in the base plate 33, tightening sickle Tighten with screw to fix A rubber plate 7 is attached to the outer surface of the right frame 31, and the rubber plate 7 is attached to the anchor bolt 8 formed on the right side wall 28 of the channel and tightened with a tightening nut to fix the screen device (1, 2, 3, 4, 5). , 32, 36, 40 and belt conveyor devices (6, 7, 8, 9, 10, 29, 31, 33, 40) are fixed and joined to the left and right of the channel where anchor bolts (4, 8) are formed The rail base plate 13 and the rail base plate support base 25 made of SS41 having the rails 14 formed on the upper surfaces of both walls 28 and 34 and the support base 25 of the rail base plate were attached to the anchor bolt 35. Insert and fasten with fastening nut to fix forward and backward running rails (13. 14) formed in a horizontal shape, the front and rear running rails (17, 18) and the rake device (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25 , 26, 27, 30, 32, 35, 36, 37, 89, and 29 are horizontal screen devices for water and sewage treatment formed by mounting the front and rear running rails 17 and 18 thereon.

The horizontal screen for the upper and the sewage treatment is a screen formed with a right angle at a horizontal angle of 35 degrees in the direction of flowing water. Therefore, the inflow water flows along the screen angle before the inflow flows through the screen. Since the foreign matter flows in the direction of the flow, the foreign matter is easily collected in the belt conveyor, and the collected foreign matter is continuously taken out to the upper part by the continuous operation of the belt conveyor and is contained in the foreign matter storage tank through the inclined hopper to be processed.

Therefore, a small amount of foreign matter is caught on the screen, so the flow of inflow is good, and there is no case where the screen-bar is warped due to the load generated on the screen due to foreign matter and water pressure. Since there is no occurrence, the work efficiency of the rake is high.

The deposits of sand or foreign matter that have joined the influent accumulate on the front of the screen unit to form a layer that does not slow the flow of the flow or cause a decrease in the processing flow rate, and there is no freezing of foreign matter on the screen-bar in winter.
