[0030] Reference Figure 1-4The utility model provides an embodiment of an efficient sand removal device for premixed concrete processing, comprising a bottom plate 1, a filter box 2 is fixedly connected to the right side of the top of the bottom plate 1, a fixing frame 3 is fixedly connected to the inner wall of the filter box 2 on both sides, a fixing box 4 is fixedly connected to the outer wall of the filter box 2 on both sides, a pull plate 5 is provided on the top of the fixing box 4, a slide 7 is fixedly connected to the bottom end of the pull plate 5, a filling filter cotton 8 is provided on the inner wall of the left slide 7, a granular activated carbon layer 9 is provided on the inner wall of the right slide 7, a tension spring 6 is provided between the pull plate 5 and the fixing box 4, a connecting pipe 10 is fixedly connected to the left end of the filter box 2, a water pump 11 is fixedly connected to the outer wall of the connecting pipe 10, one end of the tension spring 6 is connected to the pull plate 5, and the other end of the tension spring 6 is connected to the inner wall of the fixing box 4, the outer wall of the slide 7 is slidably connected to the inner wall of the fixing frame 3, and the outer wall of the pull plate 5 is slidably connected to the inner wall of the filter box 2.

[0031] Specifically, when the filled filter cotton 8 and the granular activated carbon layer 9 need to be disassembled, the pull plate 5 is pulled. When the pull plate 5 is pulled, the slide 7 is driven to slide out of the interior of the fixed frame 3. At this time, the filled filter cotton 8 and the granular activated carbon layer 9 can be replaced. During installation, because one end of the tension spring 6 is connected to the interior of the fixed box 4, the tension spring 6 will pull it when the pull plate 5 is released. When the pull plate 5 moves, the slide 7 will be inserted into the interior of the fixed frame 3. The slide 7 cooperates with the pull plate 5 to prevent misalignment during installation, thereby facilitating the replacement of the filled filter cotton 8 and the granular activated carbon layer 9, extending the service life of the equipment, and reducing the cost of maintenance and replacement.

[0032] Among them, a support platform 14 is fixedly connected to the left side of the top of the bottom plate 1, a sand removal bucket 15 is fixedly connected to the inner wall of the support platform 14, a water inlet 16 is fixedly connected to the front end of the sand removal bucket 15, a filter screen 20 is fixedly connected to the inner wall of the sand removal bucket 15, a connecting box 17 is fixedly connected to the bottom end of the sand removal bucket 15, a collecting box 18 is slidably connected to the inner wall of the connecting box 17, the left end of the connecting pipe 10 is fixedly connected to the inner wall of the sand removal bucket 15, the right end of the filter box 2 is fixedly connected to the drain outlet 12, the outer wall of the drain outlet 12 is provided with a first control valve 13, and the outer wall of the sand removal bucket 15 is provided with a second control valve 19.

[0033] Specifically, the sand removal bucket 15 is connected to the wastewater pipe, and the wastewater enters the sand removal bucket 15 from the water inlet 16. Under the action of the inertial centrifugal force and the gravity of the dirty fluid, the wastewater falls into the bottom of the sand removal bucket 15 along the cone wall. The filter screen 20 inside the sand removal bucket 15 prevents the debris from floating upward. When the debris at the bottom of the sand removal bucket 15 accumulates to a certain extent, the second control valve 19 is opened. At this time, the debris enters the connection box 17 and is then collected by the collection box 18. At this time, the water pump 11 is started to make the wastewater after sand removal enter the filter box 2 through the connecting pipe 10, and the filter cotton 8 is filled to remove visible substances such as rust and fine sand in the wastewater. The granular activated carbon layer 9 absorbs toxic substances such as discoloration and odor in the water. Then the first control valve 13 is opened. At this time, the wastewater will be discharged from the drain port 12, thereby avoiding contact with the human body and harming health, thereby improving the environmental protection of the device and the efficiency of the sand removal operation.

[0034] Working principle: First, connect the sand removal bucket 15 to the wastewater pipe, and the wastewater will enter the sand removal bucket 15 from the water inlet 16. Under the action of the centrifugal force of fluid inertia and its own gravity, the impurities fall into the bottom of the sand removal bucket 15 along the cone wall. The filter screen 20 inside the sand removal bucket 15 prevents the impurities from floating upward. When the impurities at the bottom of the sand removal bucket 15 accumulate to a certain extent, open the second control valve 19. At this time, the impurities enter the connection box 17, and then are collected in the collection box 18. At this time, start the water pump 11 to make the wastewater after sand removal enter the filter box 2 through the connecting pipe 10, fill the filter cotton 8 to remove visible objects such as rust and fine sand in the wastewater, and the granular activated carbon layer 9 absorbs toxic substances such as discoloration and odor in the water. Then open the first control valve 13. At this time, the wastewater It will be discharged from the drain outlet 12, thereby avoiding contact with the human body and endangering health, improving the environmental protection of the device and the efficiency of the sand removal operation. When it is necessary to disassemble the filled filter cotton 8 and the granular activated carbon layer 9, pull the pull plate 5. When the pull plate 5 is pulled, the slide 7 will slide out of the fixed frame 3. At this time, the filled filter cotton 8 and the granular activated carbon layer 9 can be replaced. During installation, because one end of the tension spring 6 is connected to the inside of the fixed box 4, the tension spring 6 will pull it when the pull plate 5 is released. When the pull plate 5 moves, the slide 7 will be inserted into the inside of the fixed frame 3. The slide 7 cooperates with the pull plate 5 to prevent misalignment during installation, thereby facilitating the replacement of the filled filter cotton 8 and the granular activated carbon layer 9, extending the service life of the equipment, and reducing the cost of maintenance and replacement.
