DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example

[0030] Reference Figure 1-6 As shown, a vertical flow sludge sedimentation tank includes a box body 1, a feed inlet 211 is provided at the top of the box body 1, and a filter screen 212, a filter layer 213, a guide cylinder 214 and a tank body 215 are provided on the inner wall of the box body 1 from top to bottom. The filter screen 212 is installed inside the box body 1 in an inserted manner. The filter screen 212 can be inserted into the inside of the box body 1 horizontally and corresponds to the feed inlet 211 to filter the sewage. The filter screen 212 can be disassembled and assembled by pulling the filter screen 212 horizontally, which facilitates the cleaning of the clogged filter screen 212. The filter layer 213 is installed on the inner wall of the box body 1, and the guide cylinder 214 is fixed to the inner wall of the box body 1 and is located below the filter layer 213 for guiding the sewage into the tank body 215. The tank body 215 is slidably connected to the inner wall of the box body 1, and a discharge port for the tank body 215 to enter and exit is opened at the front end of the box body 1. The outer wall of the filter 212 is fixed with a fitting plate 218 that fits against the side wall of the box 1 via a closing plate 217. The outer wall of the closing plate 217 is fixed with a sealing layer 216 that fits against the inner wall of the box 1. The outer wall of the fitting plate 218 is connected to the outer wall of the box 1 via a limiting mechanism. The sealing layer 216 can be made of rubber and has good sealing properties to prevent sewage from leaking through the side wall of the box 1. The inner wall of the box 1 is fixed with transversely distributed fixing rods 220. The interior of the filter 212 is provided with holes 219 corresponding to the fixing rods 220. After the filter 212 is inserted into the interior of the box 1, the fixing rods 220 can be inserted into the holes 219, achieving the effect of supporting and guiding the filter 212.

[0031] The limiting mechanism includes a fixed block 221, a connecting plate 222, an insertion rod 223 and a socket 224. The fixed block 221 is fixed to the outer wall of the fitting plate 218. The outer wall of the box body 1 is fixed with a connecting plate 222 corresponding to the fixed block 221. The connecting plate 222 is penetrated by the insertion rod 223. The top of the fixed block 221 is provided with a socket 224 matching the insertion rod 223. By passing the insertion rod 223 through the connecting plate 222 and inserting it into the socket 224, the fixed block 221 can be installed and fixed to the box body 1, preventing the fixed block 221 from driving the fitting plate 218 and the filter screen 212 out of the box body 1, thereby enhancing the connection stability of the equipment. A top plate 226 is fixed to the top of the rod 223. A spring 227 is wound around the outer wall of the rod 223. One end of the spring 227 is connected to the connecting plate 222 and the other end is connected to the top plate 226. Pulling the top plate 226 drives the rod 223 in and out of the socket 224. Initially, the spring 227 is compressed. When the top plate 226 is pulled upward, the spring 227 is stretched. After releasing the top plate 226, the elasticity of the spring 227 drives the rod 223 into the socket 224, achieving the installation purpose. A fixed tube 225 is fixed to the top of the connecting plate 222, which is sleeved around the outer periphery of the top plate 226. The outer wall of the fixed tube 225 is provided with a slot 228. A movable plate 229 is fixed to the outer wall of the top plate 226, which slidably cooperates with the slot 228. The movable plate 229 can slide along the inner wall of the slot 228, thereby driving the top plate 226 to move up and down stably.

[0032] A sliding block 311 is fixed to the outer wall of the pool body 215, and a sliding groove 312 is opened on the inner wall of the box body 1 to slide with the sliding block 311. The arrangement of the sliding block 311 and the sliding groove 312 ensures the stability of the movement of the pool body 215. A pull plate 321 is fixed to the outer wall of the pool body 215.

[0033] A bracket 314 is fixed to the side wall of the box body 1, and a threaded sleeve 315 is fixed to the outer wall of the bracket 314. A threaded rod 316 is threadedly connected to the inner surface of the threaded sleeve 315. A handle 317 is fixed to the end of the threaded rod 316 away from the box body 1, and the other end is rotatably connected to a baffle 313 inserted into the sliding groove 312. By rotating the handle 317, the threaded rod 316 can be driven to rotate, and under the action of the thread, the baffle 313 is driven to embed into the sliding groove 312 and fit against the outer wall of the sliding block 311 to prevent the sliding block 311 from moving forward in the sliding groove 312. A guide rod 318 is fixed to the outer wall of the baffle 313, and a guide hole 319 matching the guide rod 318 is opened inside the bracket 314. A limiting plate 320 is fixed to the end of the guide rod 318 away from the box body 1. The provision of the guide rod 318, the guide hole 319 and the limiting plate 320 can further improve the stability of the baffle 313, and the provision of the limiting plate 320 ensures that the guide rod 318 falls off from the guide hole 319.

[0034] Working principle: When needed, sewage is added into the box body 1 through the feed port 211, and then filtered through the filter mesh 212. Large-volume impurities can be filtered on the filter mesh 212, and the sewage enters the filter layer 213 from top to bottom for further filtration, and then enters the pool body 215 under the guidance of the guide cylinder 214 for precipitation.

[0035] When the filter 212 needs to be cleaned, the top plate 226 and the insertion rod 223 are moved upward by pulling the movable plate 229 upward, and the insertion rod 223 can be disengaged from the inside of the socket 224, and the spring 227 is stretched. At this time, the staff can pull the fixing block 221, the fitting plate 218 and the filter 212 outward to disengage the filter 212 from the inside of the box 1. The staff can quickly clean the filter 212 and then insert the filter 212 into the inside of the box 1 for installation and fixation.

[0036] When the pool body 215 needs to be taken out, the threaded rod 316 is driven to rotate by rotating the handle 317, and the baffle 313 is driven to disengage from the inside of the sliding groove 312 under the action of the thread. At this time, the baffle 313 and the sliding block 311 are no longer blocked. By pulling the pull plate 321 forward, the pool body 215 can be driven to disengage from the inside of the box body 1, thereby achieving the effect of taking out the pool body 215, which is conducive to cleaning the sludge.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
