Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a continuous operation type sewage sand and gravel separation equipment. Background Art

[0002] With the acceleration of industrialization, the demand for sand and gravel resources in industries such as construction and mining is increasing. However, a large amount of sewage and waste will be generated during the mining, transportation and use of sand and gravel. If these sewage and waste are discharged directly without treatment, they will cause serious pollution to the environment and affect the ecological balance and human health. In the existing technology, sand and gravel are generally intercepted by setting a filter in the transmission pipeline, and then the sand and gravel carried in the sewage are cleaned through multiple interceptions.

[0003] The Chinese invention patent with announcement number: CN116196684B discloses a sewage treatment device for mining sites. This device efficiently separates water and sand and gravel through a sand and gravel separation part. The separated sand and gravel are discharged downward from the inside of the sand and gravel separation part and finally discharged through the sand discharge part. There is no need to manually clean the inside of the device shell. It is easy to use and improves the sewage treatment efficiency at the mining site.

[0004] In the prior art, in the process of treating sand and gravel carried in sewage, a filter is often used to intercept the sand and gravel so that the sand and gravel in the sewage can be concentrated and then fished out by other equipment. The above invention also allows the filter to rotate so that the sand and gravel intercepted by the filter can be directly separated from the sewage, thereby achieving the problem of reducing the sand and gravel content in the sewage. However, during the long-term use of the filter, the sand and gravel may be stuck in the filter holes, which will cause the filter to be gradually blocked, reducing the separation efficiency of sewage and sand and gravel. At the same time, when the prior art separates sand and gravel through the filter, it can only collect the sand and gravel, but cannot classify the sand and gravel. The collected sand and gravel still need other equipment for preparation and processing, which greatly reduces the utilization rate. Summary of the invention

[0024] like Figures 1 to 5As shown, a water inlet frame 104 is fixedly mounted on the outer shell box 102, and the water inlet frame 104 is used to install the water inlet. The filter belt 103 is arranged between the water inlet frame 104 and the outer shell box 102. A gap is arranged between the water inlet frame 104 and the filter belt 103 to prevent the water inlet frame 104 and the filter belt 103 from excessive friction when the filter belt 103 is running. A collection frame 201 is also fixedly mounted on the outer shell box 102, and the collection frame 201 is a transfer box for collecting gravel. The collection frame 201 is arranged directly below the water inlet frame 104, and the collection frame 201 is arranged in the process Inside the filter belt 103, a plurality of transfer cylinders 202 are fixedly mounted on the collecting frame 201, and the transfer cylinders 202 are mounted on both sides of the collecting frame 201. An inclined surface is provided at the bottom of the collecting frame 201. The connection between the collecting frame 201 and the transfer cylinder 202 is the two lowest points of the collecting frame 201. This is to allow the sewage and gravel in the collecting frame 201 to quickly enter the transfer cylinder 202. A vibration module is provided in the collecting frame 201. During operation, gravel and sewage will accumulate in the collecting frame 201, and the vibration module will allow the gravel in the collecting frame 201 to flow into the transfer cylinder 202.

[0025] like Figures 1 to 5 As shown, the collecting frame 201 is rotatably connected with the rotating shaft 203, and an anti-blocking cam 205 is also rotatably installed on the collecting frame 201. The anti-blocking cam 205 contacts the filter belt 103.

The large sedimentation chamber 3011, the coarse sedimentation chamber 3012, and the fine sedimentation chamber 3013 are arranged in steps in the sedimentation box 301, and a sewage outlet 3014 is also arranged on the sedimentation box 301. 3014 is arranged at one end away from the large sedimentation chamber 3011, and a fine filter screen 305 is fixedly installed in the sedimentation box 301, and the fine filter screen 305 is fixedly installed on the sewage outlet 3014. A plurality of anti-collision plates 302 are fixedly installed in the sedimentation box 301, and the anti-collision plates 302 are symmetrically arranged in the sedimentation box 301, and the anti-collision plates 302 are arranged corresponding to the bottom of the transfer cylinder 202, so as to prevent the sewage flowing out of the transfer cylinder 202 from directly rushing into the large sedimentation chamber 3011.

[0027] like Figure 2 ,and Figures 5 to 7 As shown, a particle filter 303 is fixedly installed in the sedimentation box 301, and the particle filter 303 is arranged between the large sedimentation chamber 3011 and the coarse sedimentation chamber 3012 to prevent the large particles of sand in the large sedimentation chamber 3011 from entering the coarse sedimentation chamber 3012. A coarse filter 304 is fixedly installed in the sedimentation box 301, and the coarse filter 304 is arranged between the coarse sedimentation chamber 3012 and the fine sedimentation chamber 3013. The coarse filter 304 is used to prevent the coarse sand in the coarse sedimentation chamber 3012 from entering the fine sedimentation chamber 3013. The particle filter 303 and the coarse filter 304 are installed at the same height in the sedimentation box 301, and the particle filter 303 and the coarse filter 304 are inclined in the sedimentation box 301 to prevent the particle filter 303 and the coarse filter 304 from being blocked by gravel.

[0028] like Figure 2 ,and Figures 5 to 7As shown, the sedimentation box 301 is provided with a plurality of sand pumping modules, and the sand pumping modules are respectively arranged at the bottom ends of the large sedimentation chamber 3011, the coarse sedimentation chamber 3012, and the fine sedimentation chamber 3013. The sand pumping device includes a sand discharge pipe 401, a sand discharge box 402, a conveying screw 403, a conveying pipe 404, and a sand discharge motor 405. The sand discharge pipe 401 is fixedly connected to the sedimentation box 301, and the plurality of sand discharge pipes 401 are respectively arranged at the bottom ends of the large sedimentation chamber 3011, the coarse sedimentation chamber 3012, and the fine sedimentation chamber 3013. The sand discharge pipe 304 is fixedly connected to the sand discharge box 402, the sand discharge box 402 is fixedly connected to the conveying pipe 404, and the sand discharge motor 405 is fixedly connected to the sand discharge box 402. 5 is fixedly installed on the outer wall of the conveying pipe 404, the output shaft of the sand discharge motor 405 is fixedly connected with the conveying screw 403, the conveying screw 403 is arranged in the conveying pipe 404, and the end of the conveying pipe 404 away from the sand discharge box 402 is provided with a sand material outlet 406, and the setting position of the sand material outlet 406 on the conveying pipe 404 is higher than the height of the sedimentation box 301, which is to prevent sewage from flowing out of the sand material outlet 406 during the operation of the device. When the sand discharge motor 405 is started, it will drive the conveying screw 403 to rotate through the conveying pipe 404, so that the conveying screw 403 drives the sand and water in the sand discharge box 402 to be sprayed out from the sand material outlet 406.

[0029] Working principle: When the device is in use, the sewage pipe containing sand and gravel is fixed to the water inlet frame 104, and then the sewage sprayed out of the sewage pipe containing sand and gravel will flow into the collecting frame 201. After the sewage passes through the filter belt 103, the sewage and some sand and gravel that can pass through the filter sand holes on the filter belt 103 will enter the collecting frame 201, and the gravel that does not pass through the filter sand holes on the collecting frame 201 is large particles. At this time, the rotating shaft 203 will start to rotate, which will drive the filter belt 103 to transport the gravel that does not pass through the filter sand holes to one end of the gravel outlet 105, and when the rotating shaft 203 rotates, the anti-blocking cam 205 will also rotate, and the rotation of the anti-blocking cam 205 will continuously hit the filter belt Belt 103, the purpose of doing so is to prevent gravel from getting stuck in the sand filter holes. After being hit by the anti-blocking cam 205, the gravel stuck in the sand filter holes will fall into the gravel outlet 105, and the gravel transported by the filter belt 103 will also fall into the gravel receiving tray from the gravel outlet 105, thus completing the separation of gravel and sand. After the gravel falls into the collecting frame 201, it will flow to the lowest end of the collecting frame 201 with the sewage, and finally flow out of the collecting frame 201 from the transfer cylinder 202. When the sewage hits the filter belt 103, a small part of the sewage carried by the filter belt 103 during the rotation process will fall into the outer shell box 102, and be collected by the outer shell box 102 to prevent it from falling out of the device.

[0030] The sewage in the transfer cylinder 202 will flow into the sedimentation tank 301 with the gravel. When the sewage and gravel flow into the sedimentation tank 301, the anti-collision plate 302 will block the sewage and gravel at the outlet of the transfer cylinder 202, so as to prevent the sewage from directly rushing into the sedimentation tank 301, thereby making the sedimentation tank 301 lose its sedimentation effect. When the sewage and gravel enter the sedimentation tank 301, they first enter the large sedimentation chamber 3011. The function of the large sedimentation chamber 3011 is to settle the large grains of gravel, because The particle filter 303 will prevent larger gravel from entering the coarse sedimentation chamber 3012, and the gravel that does not enter the coarse sedimentation chamber 3012 will sink to the bottom of the large sedimentation chamber 3011 due to gravity and mass. After accumulating for a predetermined time, the sand pumping module at the bottom of the large sedimentation chamber 3011 will extract the large grains of gravel at the bottom of the large sedimentation chamber 3011 for classified storage, while the sewage and coarse gravel that pass through the particle filter 303 will enter the coarse sedimentation chamber 3012, and then the coarse gravel will be stored in the coarse sedimentation chamber. 3012, and when the sewage level reaches the height of the coarse filter 304, the coarse filter 304 will block the coarse gravel from entering the fine sedimentation chamber 3013, and then the sewage will carry the fine gravel into 313 for sedimentation, and then the sewage will be discharged from the device through the sewage outlet 3014, and before the sewage enters the sewage outlet 3014, the fine gravel carried by the sewage will be blocked by the fine filter 305 and precipitated in the large sedimentation chamber 3011, the coarse sedimentation chamber 3012, and the fine sedimentation chamber 3013. The large-grained gravel, coarse gravel and fine gravel at the bottom of the sedimentation chamber 3013 will be extracted from the sedimentation box 301 by different sand extraction modules and then collected by classification. During continuous use, the sewage water level in the sedimentation box 301 will always maintain the height of the coarse filter screen 304 and the fine filter screen 305. During continuous operation, by tilting the coarse filter screen 304 and the fine filter screen 305, the gravel will not excessively clog the coarse filter screen 304 and the fine filter screen 305 during use of the device.
