Description

Λ (i It (i 02418 V. Description of the invention (1) (please read the introduction to Bian Xiangmuting first) This invention is about the sludge or sand scraping rake that settles in the first or last sedimentation tank and other treatment tanks Sludge scraping rake device for treatment in the direction of one of the tanks. In the first or last sedimentation tank of the sewage disposal equipment, the sludge must be deposited at the bottom of the tank, and the sludge is scraped to the direction of the tank and then excluded from the tank. The above equipment is also generally required in the tap water treatment equipment. There is a scraper rake device that uses a chain circulation drive method. This method includes a number of rotating shafts with the shaft core facing the width of the pool and rotatable. Separately set up two sprockets, and two left and right chains mounted on the hammer wheels. A number of ladders are arranged at a certain interval along the circulation direction of the outer circumference of the chain. The ladders are arranged along the The guide rail at the bottom of the pond moves the sludge at the bottom of the pond to a direction with a ladder plate and rakes into the pit. The sludge raked into the pit is discharged to the outside of the pond by the pump. The structure of this chain drive method is huge and complicated cost High, difficult to construct, and because of the need for circular movements, maintenance management costs are high, and the economy is not good. The Ministry of Economic Affairs has issued a new method for printing by the A Gongji Cooperative Society. The linear reciprocating motion of the bottom of the pool. This method includes an elongated guide (rail) provided on the bottom of the pool, an operating body that moves along the guide, a driving device (rope, etc.) that reciprocates the operating body, and equipment The scraping member provided on the action body. This method uses the movement of the scraping rake member to scrape the sludge deposited on the bottom of the treatment tank to one direction and exclude it from the tank. This method has the following disadvantages. The guide is made of The left and right tracks separated from each other in the width direction of the pool are constructed from 3 to 81.U. 丨 0,000 sheets (11 > in this paper, the paper is used in the standard a B Jiayu standard (CNS) T 4 regulation «5 (210 X 297; ":) -〇24ib Λ () _ It (i_ V.

Invention description ( 5) The operating body 108 makes it reciprocate. When the operating body returns to the opposite side of the pit and the motor starts to rotate, the operating body 108 is pulled by the first tab 114. The scraper member 131 abuts against the stopper 13 2 While keeping the vertical state forward, the sludge accumulated in the bottom 104 of the tank can be scraped to the direction of the pit. At this time, the scraper 112 scrapes the sediment on the upper guide 106, and the roller 109 , 110 111 stably guides the operating body 108. When the operating body 108 reaches the pit 133, the motor starts to reverse. At this time, the rope 117 resists the elastic force of the spring 12 4 being pulled, so that the scraper member 131 reverses to retreat Therefore, the scraper member 131 can move back without contacting the sludge. At this time, the scraper 132 scrapes off the sediment again. A storage box can also be provided on the operating body 108, and microorganisms can be placed in the box for decomposition Sludge. The trajectory of the actuator 108 and guide 105 etc. need not be a straight line, but can also be a circular or rectangular trajectory. Not only can the sedimentation tank be treated, but also dams, rivers, general ponds, etc. can be treated. The body 108 can also be equipped with an air injection device, which can be used for purification operations. There are only one of the above examples. Tank, but it can also be equipped with a power on many adjacent pools to drive many scraper members. It is also possible to fix the trough-shaped conveyor trough in front of the end wall 3 of one C-pillar side, so that the front side of the trough is under the water surface, A long weir trough with an oblong cross section is installed at the front of the shaft via a rotating shaft, and the scum on the water surface is scraped by the weir trough, or the scum is guided into the conveying trough. At this time, if the weir groove is shaken by the action of the protrusion provided on the rope 117, it becomes a more ideal device. —7 — (Zhanxianjian 5ίί-ί1ί · And Note-. ¾ ^ • Xiang Sun hard "wooden page"

When the dross scraping raking plate 229 swings towards the rear, The magnet 230 can be attracted to the fixed magnet 231 °. The rocking of the scraper blade 229 toward the rear occurs by the action body 227 traveling toward the scum removal device 240 side and then abutting against the roller 232. When the dross scraper blade 229 is in When retracted in the opposite direction of the scum removal device 240 while being attracted by the fixed magnet 231, abut It comes off the plate 233 and separates from the magnet 231, and then maintains its vertical state with its own weight. Pressed by the ball department, the press roller 23 5 is printed by the co-operative consumer cooperative, and is provided on the moving body 22 7 via the brace 23 4, The roller 235 moves with the operating body 227 in the direction of the scum removal device 245 and climbs onto the convex plate 247 to push the weir groove 246 under the water surface. Therefore, the scum floating on the water surface can pass the weir groove 2 46 is guided into the transport trough 241. The floating haw flows in one direction of the transport trough 241 and flows into the adjacent transport trough through the communication transport trough 242, and then flows into the pit provided at the end through other transport troughs It is excluded. 'When the push roller 235 retreats, the weir 246 rises due to its own weight and stops guiding the scum. The reciprocating movement of the chain 225 is controlled by the switch 236 fixed on the side of the guide rail 222. Because Scum scraper blade 229 follows the water-15.-This paper is used in the standard "Ming Jia Caiping (CNS) IM regulations (210X297) and 81. 6. 10,000¾ (I!), 02418 Λ (ί ____ η ο V. Description of the invention (14.) The position changes and follows, so the width in the up and down direction is slightly larger. The free end of the slag scraping rake plate 229 can also be equipped with a buoy to make it buoyant. The sludge scraping rake device in the above embodiment can be installed in addition to the sedimentation tank or before it reaches the treatment plant Sewage or tap water piping, treatment of grit chambers, flow channels, etc. As mentioned above, the structure of the sludge scraping rake device of the present invention is very simple, easy to construct, low in cost, and low in maintenance and management fees.
