[0040] 1. A spiral sheet one and a number of stirring blocks are fixedly connected to one side surface of the rotating shaft. The interior of the treatment frame is divided into three treatment spaces by two first filter frames. In one treatment space, relatively large solid suspended matters are filtered by the first filter frame. After the sewage is filtered, it can enter a receiving frame, and treatment agents can be added to the receiving frame. The agents can flow along the inside of the connecting pipe following the sewage. The spiral sheet one and the stirring blocks can be driven to rotate by the first rotating shaft. The sewage is stirred by the stirring blocks, and at the same time, the agglomerated impurities are conveyed by the spiral sheet one.

[0041] 2. The pushing plate is slidably connected to the shielding frame. Solid impurities can be deposited inside the conveying frame. The opening groove of the support plate can be blocked by the baffle plate. Then, the impurities can be conveyed into the U-shaped frame by the second rotating shaft and the spiral sheet two. After a certain amount of impurities are collected in the U-shaped frame, the pushing plate can be moved upward. The end of the conveying frame is blocked by the shielding frame, and the sewage and impurities are squeezed by the pushing plate and the baffle plate, so that the sewage enters the bottom of the U-shaped frame through the round groove. After a certain amount of sewage is discharged, the baffle plate can be moved away from the opening groove. When the pushing plate continues to move, the solid impurities can be pushed to the top of the support plate. Then, the opening groove can be blocked again by the baffle plate, so that most of the impurities remain on the top of the support plate, and the pushing plate is moved downward to the original position. The sewage inside the U-shaped frame can be squeezed into the fixed pipe by the pushing plate, and the sewage is re-conveyed into the treatment frame through the fixed pipe. In this way, during the sewage treatment process, the solid impurities inside the treatment frame can be cleaned, which is conducive to the continuous treatment of sewage.

Detailed implementation manners

[0054] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0055] Please refer to Figures 1-6 , in an embodiment of the present invention, an integrated multi-stage municipal sewage treatment device includes a processing module 100, and three collecting modules 200 are arranged on one side of the processing module 100;

[0056] The processing module 100 includes a processing frame 110, a driving mechanism 120, two partition boards 130, and a conveying pipe 150;

[0057] The treatment box 110 can hold sewage. Two first filter boxes 111 are fixedly connected to the inner side surface of the treatment box 110. A first filter net is fixedly connected inside the first filter box 111. The inner part of the treatment box 110 is divided into three treatment spaces by the two first filter boxes 111. The partition 130 abuts against the adjacent first filter box 111, and the first filter net abuts against the adjacent partition 130. The driving mechanism 120 is arranged on the side surface of the treatment box 110 away from the collection module 200. The two partitions 130 are both fixedly connected to the inner side surface of the treatment box 110. The heights of the two partitions 130 decrease in sequence. A receiving frame 131 is fixedly connected to the top of the side surface of the partition 130. The receiving frame 131 is located on the side of the partition 130 away from the adjacent first filter box 111. A connecting pipe 133 communicates with the bottom surface of the receiving frame 131. The connecting pipe 133 is U-shaped, and both long ends of the connecting pipe 133 are inclined. The bottom of the receiving frame 131 is inclined. The end of the connecting pipe 133 corresponds to the lowest part of the bottom of the receiving frame 131. Two first rotating shafts 134 are rotatably connected to the inner side surface of the connecting pipe 133. A first spiral piece 137 and a number of stirring blocks 138 are fixedly connected to the side surface of the first rotating shaft 134. A conveying pipe 150 is fixedly connected inside the treatment box 110.

[0058] Specifically, after the sewage is conveyed into one of the treatment spaces, the relatively large solid suspended matters can be filtered by the first filter net in one of the first filter boxes 111. After the sewage is filtered, it can pass over the top of one of the partitions 130, and then the sewage can enter one of the receiving frames 131. A flocculant can be added into the receiving frame 131. The flocculant can follow the sewage into the connecting pipe 133 and then flow along the inside of the connecting pipe 133. The driving mechanism 120 can drive the first rotating shaft 134 to rotate. The first rotating shaft 134 can drive the first spiral piece 137 and the stirring blocks 138 to rotate. The sewage is stirred by the stirring blocks 138, and at the same time, the agglomerated impurity masses are conveyed by the first spiral piece 137. After the sewage and the impurities flow out of the connecting pipe 133, they can enter the treatment space in the middle of the treatment box 110, and then are filtered by the first filter net on another first filter box 111. The sewage can enter another receiving frame 131 in the treatment box 110. A treatment chemical is added into the receiving frame 131, and then the sewage is stirred by the stirring blocks 138 in another connecting pipe 133 to reduce the content of harmful substances in the sewage. After the sewage flows out of another connecting pipe 133, it can enter the treatment space on the other side in the treatment box 110, and then the sewage can be discharged through the conveying pipe 150. When stirring, only the sewage in the connecting pipe 133 can be stirred. The amount of stirred sewage is relatively small, and the stirring is relatively easy. The stirring of the sewage by the stirring blocks 138 is beneficial to the mixing of the chemical agent and the sewage, and is beneficial to improving the treatment effect on the sewage.

The bevel gear two 170 can drive the adjacent bevel gear three 180 to rotate, so that the rotating shaft two 141 rotates. The rotating shaft two 141 can drive the spiral blade two 142 to rotate. When the spiral blade two 142 rotates, it can convey the impurities aggregated in the conveying frame 140 into the collection module 200, so as to collect and process the impurities in the processing frame 110.

[0067] As Figures 7-10 shown, in this embodiment, the collection frame 210 is fixedly connected to the side surface of the processing frame 110. The inner side surface of the collection frame 210 is fixedly connected with an L-shaped plate 212. The inner side surface of the collection frame 210 is fixedly connected with a fixed pipe 211. The three fixed pipes 211 respectively correspond to the three processing spaces of the processing frame 110. The bottom end of the fixed pipe 211 communicates with the bottom of the L-shaped plate 212. The U-shaped frame 220 is fixedly connected to the bottom of the inner side surface of the collection frame 210. The conveying frame 140 communicates with the inside of the adjacent collection frame 210, and the conveying frame 140 corresponds to the inside of the adjacent U-shaped frame 220. The opening of the U-shaped frame 220 corresponds to the end of the conveying frame 140. The shielding frame 240 is located at the bottom of the conveying frame 140. The bottom end of the fixed pipe 211 corresponds to the inside of the U-shaped frame 220. The support plate 230 is fixedly connected to the top surface of the U-shaped frame 220. The side surface of the support plate 230 is fixedly connected to the inner side surface of the collection frame 210. The L-shaped plate 212 and the inside of the collection frame 210 can enclose a collection space at the top of the support plate 230. The support plate 230 is provided with an opening groove corresponding to the U-shaped frame 220. A baffle 231 is slidably connected to the inner side surface of the support plate 230 corresponding to the opening groove. The baffle 231 can slide horizontally inside the support plate 230. The shielding frame 240 is slidably connected to the inner side surface of the U-shaped frame 220, and the side surface of the shielding frame 240 is slidably connected to the inner side surface of the collection frame 210.

When solid impurities are deposited inside the conveying frame 140, the second spiral blade 142 can be driven to rotate by the second rotating shaft 141 to convey the impurities into the U-shaped frame 220. After a certain amount of impurities are collected in the U-shaped frame 220, the sliding cylinder 271 can be driven to move upward by the electric telescopic rod 272. The sliding cylinder 271 can drive the pushing plate 250 to move upward, so that the shielding frame 240 moves upward to block the end of the conveying frame 140. Then, when the pushing plate 250 continues to move, the sewage and impurities can be squeezed by the pushing plate 250 and the baffle 231, so that the sewage passes through the round groove and enters the bottom of the U-shaped frame 220. After most of the sewage is discharged, the baffle 231 can be moved away from the opening groove through the adjusting mechanism 260. At this time, when the pushing plate 250 continues to move, the solid impurities can pass through the opening groove and move to the top of the support plate 230. Then, the baffle 231 can be moved towards the opening groove again to block the opening groove again, so that most of the impurities remain on the top of the support plate 230 and the baffle 231. Then, the pushing plate 250 can be moved downward to its original position, and when the pushing plate 250 moves downward, the sewage in the U-shaped frame 220 can be squeezed, and the sewage in the U-shaped frame 220 is squeezed into the fixed pipe 211, and the sewage is re-transported into the treatment frame 110 through the fixed pipe 211. In this way, during the sewage treatment process, the solid impurities in the treatment frame 110 can be cleaned, which is beneficial to the continuous treatment of sewage.

[0070] Embodiment 2

[0071] On the basis of Embodiment 1, as Figure 7 shown, in this embodiment, the adjusting mechanism 260 includes an adjusting frame 261, an adjusting motor 262, an adjusting screw rod 263, and a sliding block 264;

[0072] The adjusting frame 261 is fixedly connected to the inner side surface of the collection frame 210. The adjusting motor 262 is fixedly connected to the side of the adjusting frame 261 close to the U-shaped frame 220. The adjusting screw rod 263 is rotatably connected to the inner side surface of the adjusting frame 261. The output end of the adjusting motor 262 is in transmission connection with the end of the adjusting screw rod 263. The sliding block 264 is slidably connected to the inner side surface of the adjusting frame 261. The sliding block 264 can slide along the inside of the adjusting frame 261. The top surface of the sliding block 264 is fixedly connected to the bottom surface of the baffle 231 on the side away from the U-shaped frame 220. The adjusting screw rod 263 is in threaded connection with the inside of the sliding block 264.

[0073] During specific implementation, the motor 262 can be adjusted to drive the adjusting lead screw 263 to rotate forward or backward. The rotation of the adjusting lead screw 263 can cause the sliding block 264 to move inside the adjusting frame 261. The adjusting frame 261 can drive the baffle 231 to move inside the support plate 230. When the adjusting lead screw 263 rotates forward, the sliding block 264 can drive the baffle 231 to move towards the opening groove. When the adjusting lead screw 263 rotates backward, the baffle 231 can be driven by the sliding block 264 to move away from the opening groove, so that the sliding block 264 blocks the opening groove or exposes the opening groove, and the position of the baffle 231 is adjusted through the adjusting mechanism 260.

[0074] As Figures 10-11 shown, in this embodiment, two strip-shaped grooves 241 are provided on both side surfaces of the shielding frame 240. Two abutting blocks 221 are fixedly connected to the corresponding inner side surfaces of the U-shaped frame 220 for the strip-shaped grooves 241. A clamping groove 243 is provided at the bottom of the inner side surface of the strip-shaped groove 241. Two plug-in blocks 256 that are slidably connected to the inner side surface of the adjacent clamping groove 243 are slidably connected to both sides of the push plate 250. A spring three 257 fixedly connected to the inside of the push plate 250 is fixedly connected to the side surface of the plug-in block 256. Grooves are provided on both sides of the push plate 250. The plug-in block 256 slides in the groove, and the end of the spring three 257 is fixed in the groove. An arc surface is provided at the top of the plug-in block 256 corresponding to the abutting block 221. The top of the plug-in block 256 is provided with an arc surface and a flat surface. Under the action of the spring three 257, the position of the plug-in block 256 can be maintained, so that the flat surface at the top of the plug-in block 256 contacts the inner side surface of the clamping groove 243. Two connecting grooves 222 are provided on the corresponding top surfaces of the two side surfaces of the U-shaped frame 220 for the abutting blocks 221. An arc-shaped tooth block one 223 that is slidably connected to the inner side surface of the adjacent strip-shaped groove 241 is slidably connected to the inner side surface of the connecting groove 222. The arc-shaped tooth block one 223 is located on the top of the adjacent abutting block 221. The abutting block 221 can slide relative to the strip-shaped groove 241. A spring one 224 fixedly connected to the inner side surface of the connecting groove 222 is fixedly connected to the side surface of the arc-shaped tooth block one 223. An arc-shaped tooth block two 242 is embedded at the bottom of the inner side surface of the strip-shaped groove 241. The arc-shaped tooth block two 242 is located on the top of the adjacent plug-in block 256.

[0075] During specific implementation, when the push plate 250 is moved upward by the electric telescopic rod 272, the push plate 250 can push the shielding frame 240 to move upward inside the U-shaped frame 220 through the insertion block 256 and the clamping groove 243, so that the shielding frame 240 can successfully block the end of the adjacent conveying frame 140, separating the inside of the U-shaped frame 220 from the inside of the conveying frame 140. When the second arc tooth block 242 passes through the abutting block 221 and then contacts the first arc tooth block 223, under the action of the first spring 224, the first arc tooth block 223 can be abutted against the adjacent second arc tooth block 242. Since both the first arc tooth block 223 and the second arc tooth block 242 have arc teeth, when the second arc tooth block 242 continues to move upward, the second arc tooth block 242 can squeeze the arc teeth on the first arc tooth block 223 through the arc teeth on it, causing the first arc tooth block 223 to move into the connecting groove 222, so that the second arc tooth block 242 can successfully move upward relative to the first arc tooth block 223. At this time, the arc surface at the top of the insertion block 256 will contact the bottom of the abutting block 221, and the bottom of the abutting block 221 squeezes the arc surface at the top of the insertion block 256, causing the insertion block 256 to move into the groove, so that the flat surface at the top of the insertion block 256 corresponds to the inner top surface of the clamping groove 243, and the arc surface at the top of the insertion block 256 corresponds to the inner top surface of the clamping groove 243. In this way, after the top surface of the shielding frame 240 contacts the bottom surface of the support plate 230, the support plate 230 can prevent the shielding frame 240 from continuing to move upward, while the push plate 250 continues to move upward, and the inner top surface of the clamping groove 243 will squeeze the arc surface of the insertion block 256, causing the insertion block 256 to be retracted into the groove, so that the insertion block 256 is separated from the clamping groove 243, and the push plate 250 can move upward relative to the shielding frame 240. At this time, under the action of the first spring 224, the first arc tooth block 223 can be engaged with the adjacent second arc tooth block 242, providing resistance to the downward movement of the shielding frame 240 through the first arc tooth block 223, and under the action of the third spring 257, the insertion block 256 is abutted against the inner side surface of the shielding frame 240. When the push plate 250 moves upward, the height of the shielding frame 240 can be generally maintained;

[0076] After the push plate 250 pushes the impurities to the top of the support plate 230 and then moves the push plate 250 downward, the shielding frame 240 can be toggled to move downward through the insertion block 256, so that the shielding frame 240 moves downward to its original position. And when the push plate 250 moves relative to the shielding frame 240 and the push plate 250 moves back to the position of the clamping groove 243, under the action of the third spring 257, the insertion block 256 can be inserted into the clamping groove 243, and the bottom surface of the insertion block 256 can push the clamping groove 243 to move downward, so that the shielding frame 240 and the push plate 250 move downward to their original positions.

[0077] Such as Figures 8-9As shown, in this embodiment, a fixing ring 251 is fixedly connected to the top of the inner side surface of the circular groove. A second filter screen is fixedly connected inside the fixing ring 251. A blocking block 252 is slidably connected to the bottom of the inner side surface of the circular groove. Two first sliding rods 253 are fixedly connected to the bottom surface of the fixing ring 251. A second sliding rod 254 is fixedly connected to the top surface of the blocking block 252 and is slidably connected to the inner side surface of the adjacent first sliding rod 253. A second spring 255 is fixedly connected to the inner bottom surface of the second sliding rod 254 and is fixedly connected to the inner top surface of the first sliding rod 253. The first sliding rod 253 and the second sliding rod 254 can cover the second spring 255. Under the action of the second spring 255, the position of the blocking block 252 can be maintained.

[0078] During specific implementation, when the pushing plate 250 moves upward and squeezes impurities through the pushing plate 250 and the baffle 231, the sewage can pass through the second filter screen inside the fixing ring 251 and enter the inside of the circular groove. Then, the sewage can squeeze the blocking block 252, causing the blocking block 252 to move downward, so that the blocking block 252 is separated from the circular groove. At this time, the sewage can fall to the inner bottom of the U-shaped frame 220 through the side of the blocking block 252;

[0079] After the pushing plate 250 pushes the impurities to the top of the support plate 230 and then moves the pushing plate 250 downward to squeeze the sewage, due to the action of the second spring 255, the blocking block 252 is inserted into the circular groove, and the pushing plate 250 can prevent the blocking block 252 from moving upward continuously. In this way, the pushing plate 250 and the blocking block 252 can squeeze the sewage, causing the sewage to enter the fixed pipe 211. The sewage in the fixed pipe 211 can fall back into the treatment frame 110 from the top end of the fixed pipe 211.

[0080] A one-way valve can be provided at the bottom end of the fixed pipe 211 to prevent the sewage from flowing back into the U-shaped frame 220. A fixing frame that can support the bottom of the second filter screen can be provided inside the circular groove.
