[0018] Compared with the prior art, the present invention provides a sewage suction and purification vehicle with a filtering device, which has the following beneficial effects:

[0019] 1. The present invention sets up a filter sleeve and a filter arc plate. When sewage enters the interior of the carriage through the sewage inlet pipe, it will first pass through multiple filtrations of the filter sleeve and the filter arc plate. Moreover, due to the unique shape and structural design of the filter sleeve and the filter arc plate, it can ensure that the filtered sewage will not affect the already filtered sewage, thereby further improving the filtration effect of the sewage.

[0020] 2. The present invention sets up a sliding cylinder. By squeezing the spring through the filter sleeve, the opening one formed on the surface of the sliding cylinder can enter the filter sleeve. At this time, the sewage and impurities in the filter sleeve enter the interior of the sliding cylinder under the action of gravity through the opening one, and then are discharged through the opening two. In this way, it can avoid adverse effects on the subsequent filtration effect due to excessive impurities.

[0021] 3. The present invention sets up an arc-shaped groove. When sewage flows along the surface of the cross bar, the impurities in the sewage can fall into the arc-shaped groove for collection. In addition, by setting up a plug rod, when the impurities in the arc-shaped groove accumulate too much, the plug rod can be pulled out to discharge the impurities from the plug rod, thereby ensuring the subsequent filtration effect of the arc-shaped groove on the impurities.

[0022] 4. The present invention sets up a cross bar. When sewage flows along the thread groove formed on the surface of the cross bar, it will naturally fall into the arc-shaped groove. Then, by setting up a pressing plate to effectively slow down the flow rate of the sewage, and with the auxiliary effect of the limiting sleeve, it can make the impurities accumulate in the arc-shaped groove more excellently, thereby achieving a better impurity separation effect.

After the sewage is discharged into the carriage 2 through the sewage inlet pipe 3, the sewage falls onto the surface of the filtering sleeve 231 under the blockage of the fixing ring 232. Among them, the large impurities in the sewage are blocked by the filtering sleeve 231, and the blocked large impurities slide down along the filtering sleeve 231 to the first fixing block 235 for collection. When the sewage gradually increases, the impurities in the sewage precipitate at the bottom, and the sewage above passes through the filtering sleeve 231 and enters the interior of the filtering sleeve 231.

The top of the support plate 241 is fixedly connected with a fixing plate 1 242 and a fixing plate 243. The fixing plate 1 242 is arranged on the right side of the fixing plate 243. The top of the support plate 241 is fixedly connected with a pumping component 244. The input end pipeline of the pumping component 244 passes through the partition 1 21 and extends to the top of the filter arc plate 234. The output end of the pumping component 244 passes through the fixing plate 1 242. The top of the support plate 241 is fixedly connected with a top fixed connection limit ring 245. A leakage hole 3 2451 is opened on the surface of the support plate 241. The leakage hole 3 2451 is located inside the limit ring 245. The pumping component 244 is used to pump the filtered sewage from the filter arc plate 234 to the top of the support plate 241. A fixing block 246 is fixedly connected to the top of the support plate 241. The right side of the fixing block 246 is fixedly connected to the fixing plate 1 242. The left side of the fixing block 246 penetrates the fixing plate 243 and contacts the limiting ring 245. A leakage hole 1 2431 is provided in the middle of the fixing plate 243. Two leakage holes 2432 are provided on the surface of the fixing plate 243. The heights of the two leakage holes 2432 are higher than the height of the leakage hole 1 2431. Sewage is continuously accumulated on the support plate 241. When the accumulated sewage reaches a certain amount, the sewage leaks from the leakage hole 2432 to the left side of the fixing plate 243. The sewage gradually accumulates and then covers the limiting ring 245. The water entering the limiting ring 245 leaks down along the leakage hole 3 2451.

When the sewage flows on the second fixed block 246, the impurities inside the sewage fall into the arc groove 247 after passing through the arc groove 247. When a large amount of impurities are accumulated in the arc groove 247, the impurities are discharged from the plug rod 248 by pulling out the plug rod 248.

[0051] The sewage flows along the surface of the cross bar 249, and gradually makes impurities fall into the arc-shaped groove 247 through the thread groove 2491 opened on the surface of the cross bar 249.
