Description

Technical Field

[0001] The utility model belongs to the field of sewage treatment equipment, in particular to a scum scraping device for sewage treatment. Background Art

[0002] In sewage treatment work, flotation machines are often used to convert suspended impurities in water into scum, and then scrapers are used to clean the scum. Scrapers, also known as slag scooping machines and slag removers, mainly use transmission components to drive scrapers to perform reciprocating motion to scrape the scum on the water surface. The existing scraper machine will set a mounting plate for fixing the scraper between two transmission chains, and then drive a row of bolts between the scraper and the mounting plate for fixing. There are two main ways to install the scraper. One is to first connect the mounting plate to the transmission chain, and then connect the scraper to the mounting plate. This method requires manual operation above the sewage tank, which is inconvenient and more dangerous. The second method is to first fix the mounting plate and the scraper, and then two people work together to lift the plate to the connecting part of the transmission chain for fixing. The sewage tank is large in width and the plate has a certain weight. During operation, it is also necessary to keep the plate balanced and align the screw holes.

[0003] The above two installation methods both require at least two people to implement when facing a wider scraper, and the scraper usually has more than one scraper, which is labor-intensive, dangerous, and inefficient. Utility Model Content

[0004] In order to overcome the deficiencies and existing problems of the prior art and solve the problems of high work intensity, high risk and low efficiency when disassembling and assembling the scraper of the scraper, the utility model provides a scum scraping device for sewage treatment.

DETAILED DESCRIPTION

[0020] In order to facilitate understanding by those skilled in the art, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, a scum scraping device for sewage treatment includes a water tank 100 for storing sewage to be treated. A driving drive shaft 110 and a driven drive shaft 120 are provided on the top of the water tank 100. The driving drive shaft 110 is connected to a rotation drive mechanism 111, which is a reduction motor. The reduction motor is used to drive the driving drive shaft 110 to rotate. A first transmission chain 130 and a second transmission chain 140 are connected between the driving drive shaft 110 and the driven drive shaft 120. The driving drive shaft 110 drives the transmission chains to move. A first fixing seat 150 is provided on the first transmission chain 130, which is connected to two adjacent pins 141 on the first transmission chain 130. The second transmission chain 140 is provided with a second fixing seat 160 , which is connected to two adjacent pins 141 on the second transmission chain 140 . The connection through the two pins 141 can keep the first fixing seat 150 and the second fixing seat 160 balanced and prevent rotation.

[0022] like Figure 2 、 3As shown, a guide bar 170 is provided between the first fixing seat 150 and the second fixing seat 160, and a slide seat 180 is slidably connected to the guide bar 170. The guide bar 170 is a T-shaped structure, and the bottom of the slide seat 180 is provided with a first slide 181 that cooperates with the guide bar 170. The guide bar 170 is small in size and light in weight, and is more convenient to install. It is used to assist the installation of the slide seat 180. When installing the slide seat 180, align the first slide 181 with the guide bar 170 and push it in until one end of the slide seat 180 reaches the second fixing seat 160. A scraper 190 is slidably connected to the chute seat 180. This scraper 190 is used to scrape scum from the sewage surface. The scraper 190 connects to the chute seat 180 via an inverted T-shaped sliding portion 191. A second chute 182 is provided on the upper portion of the chute seat 180 to mate with the sliding portion 191. To install the scraper 190, simply align the sliding portion 191 with the second chute 182 and push it into place. Both the guide bar 170 and the scraper 190 engage with the second fixed seat 160. A stop block 161 is provided on the second fixed seat 160. This stop block 161 has a first retaining groove 162 for the guide bar 170 to engage, and a second retaining groove 163 for the scraper 190 to engage. A notch 193 is provided at the end of the scraper 190 to allow the scraper 190 to engage the second retaining groove 163. To install the guide bar 170, simply snap one end into the first retaining groove 162. When installing, the scraper 190 is pushed along the second sliding groove 182 on the sliding groove seat 180 until the end is locked into the second limiting groove 163.

[0023] like Figure 4 As shown, a snap mechanism 200 is provided between the scraper 190 and the chute seat 180. The snap mechanism 200 includes a support block 210. One end of the support block 210 is connected to a snap block 220, and the other end is connected to one side of the chute seat 180 via a rotating shaft. A spring 230 is also connected between the inner side of the support block 210 and the chute seat 180. One end of the scraper 190 is provided with an opening 192, and the snap block 220 is snapped at the opening 192. The spring 230 generates a certain pulling force between the chute seat 180 and the support block 210, which can prevent the snap block 220 from opening and causing the plate to loosen. When disassembling the scraper 190, the operator can pull the snap block 220 open with one hand and use the opening 192 as a handle with the other hand to pull out the scraper 190.

[0024] like Figure 1As shown, a scum box 102 is further provided at one end of the water tank 100, and a guide plate 101 is provided at one end of the top of the water tank 100. The guide plate 101 is connected to the scum box 102, and the scraper 190 scrapes the scum so that the scum enters the scum box 102 from the guide plate 101. The connection between the guide plate 101 and the scum box 102 is slightly higher than the sewage water level, which can reduce the scraper 190 from bringing too much water into the scum box 102 when scraping out the scum.

[0025] Working process: During installation, insert one end of the guide bar 170 into the first limiting groove 162, and fix the other end to the first fixed seat 150 with bolts, then align the first slide groove 181 at the bottom of the slide groove seat 180 with the guide bar 170 and slide it in until one end of the slide groove seat 180 hits the stop block 161, and then use bolts to fix the other end of the slide groove seat 180 to the first fixed seat 150. After the slide groove seat 180 is fixed, open the block 220 of the snap mechanism 200, align the slide bar at the bottom of the scraper 190 with the second slide groove 182 and slide it in until the notch 193 of the scraper 190 is stuck on the stop block 161, and then snap the block 220 into the opening 192. To disassemble, open the block 220, pull out the scraper 190 through the opening 192, then loosen the bolts connecting the chute seat 180 to the first fixing seat 150, pull out the chute seat 180, and finally remove the guide bar 170. In this embodiment, both the installation and removal process can be completed by a single person on the first fixing seat 150 side, making the process simple and efficient.

[0026] The above embodiments are preferred implementations of the present invention and are not intended to limit the present invention. Without departing from the scope of the present invention, any obvious replacements are within the scope of protection of the present invention.
