Description

Technical Field

[0001] This utility model relates to the field of purification device technology, and in particular to a dehydration and purification device for regenerating water glass sand. Background Technology

[0002] The principle of wet recycling of water glass sand is to remove the residual binder film on the old sand particles by utilizing the dissolving effect of water on the old sand particles, the mechanical stirring effect of the wet recycling mechanism on the old sand particles, and the scrubbing effect between sand particles during the recycling process. Specifically, during the wet recycling process, the residual binder film on the old sand particles, such as residual water glass binder, salt, ester, etc., are all soluble in water. Through the dissolving effect of water on the old sand particles, the residual binder can be dissolved in the water. At the same time, the mechanical stirring of the old sand particles by the wet recycling mechanism and the scrubbing effect between the sand particles and the components (or between sand particles) can further remove the residual binder on the old sand particles. After wet recycling, the residual binder on the surface of the old sand particles is removed, and the quality of the recycled sand is improved.

[0003] An existing dehydration and purification device for the regeneration of water glass sand (publication number: CN212121575U) has at least the following drawbacks:

[0004] In the aforementioned patent, during the dehydration process, most of the sand particles settle at the bottom of the cylinder through sedimentation. Wastewater that cannot be discharged through the overflow trough is discharged through the filter cap outlet. However, the filter cap is located at the bottom of the deposited sand particles. After the sand particles settle, they will cover the filter cap. As the wastewater flows from top to bottom through the gaps between the sand particles, some impurities in the wastewater will be filtered by the sand particles and adhere to the surface of the sand particles. This situation not only reduces the cleanliness of the sand particles but may also affect the subsequent regeneration effect. Therefore, it is necessary to propose a dehydration and purification device for water glass sand regeneration to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dehydration and purification device for the regeneration of water glass sand.

[0024] Reference Figures 1-4A dewatering and purification device for regenerating water glass sand includes a preliminary treatment chamber 1, a secondary treatment chamber 2 located on one side of the preliminary treatment chamber 1, a PLC controller located on the bottom surface of the preliminary treatment chamber 1, and a dewatering component located inside the preliminary treatment chamber 1 for dewatering the water glass sand. The dewatering component includes a spiral blade 3 movably fitted inside the preliminary treatment chamber 1. A first drive motor 4 is fixedly installed on one side of the preliminary treatment chamber 1, and one end of the drive shaft of the first drive motor 4 is fixedly installed with the spiral blade 3. A first rectangular through hole is opened on the outer circular wall of the preliminary treatment chamber 1, and a guide hopper 5 is fixedly fitted inside the first rectangular through hole. A rotating cylinder 6 is located inside the secondary treatment chamber 2. A support frame 20 is fixedly sleeved on the inner circular wall of the rotating drum 6. A first circular through hole is opened at both ends of the secondary treatment chamber 2. The inner circular wall of the first circular through hole is movably sleeved with the support frame 20. A second drive motor 7 is fixedly installed on one side of the secondary treatment chamber 2. One end of the drive shaft of the second drive motor 7 is fixedly installed with the support frame 20. Several second rectangular through holes are opened on the outer circular wall of the rotating drum 6. A filter screen 8 is fixedly installed inside the second rectangular through hole. A first fixing hole 21 and a second circular through hole are opened on one side of the secondary treatment chamber 2. A discharge hopper 11 is fixedly sleeved inside the first fixing hole 21. A liquid outlet pipe 12 is fixedly sleeved on the inner circular wall of the second circular through hole. A drying assembly is used to dry water glass sand.

[0025] In use, a mixture of water glass sand and water is fed into the interior of the primary treatment chamber 1 through the feed pipe 13. The water glass sand will settle at the bottom of the primary treatment chamber 1. The first drive motor 4 is started to drive the spiral blades 3 to rotate. The rotating spiral blades 3 push the water glass sand at the bottom of the primary treatment chamber 1 upward. Water flows out through the gap between the spiral blades 3 and the primary treatment chamber 1 and overflows through the overflow pipe 14, thereby initially removing water from the water glass sand. The water glass sand falls into the rotating cylinder 6 inside the secondary treatment chamber 2 through the guide hopper 5. The rotating cylinder 6 is started to drive the support frame 20 to rotate, which in turn drives the rotating cylinder 6 to rotate. Several filter screens 8 are set on the outside of the rotating cylinder 6, and several flipping plates 15 are used to tumble the water glass sand. Since the rotating cylinder 6 is set at an inclination, the water glass sand flows to the lower right. The water flows out through the filter screens 8 and falls to the bottom of the secondary treatment chamber 2 and is discharged through the liquid outlet pipe 12.

[0026] In this embodiment, the drying assembly includes: an industrial hot air blower 9, which is disposed on one side of the secondary processing chamber 2. A third circular through-hole is provided on one side of the secondary processing chamber 2, and the inner wall of the third circular through-hole is fixedly sleeved with the air outlet pipe of the industrial hot air blower 9. An exhaust port 10 is provided on the top surface of the secondary processing chamber 2. A fourth circular through-hole is provided on the top surface of the preliminary processing chamber 1, and a feed pipe 13 is fixedly sleeved on the inner wall of the fourth circular through-hole. A second fixing hole 22 is provided on one side of the preliminary processing chamber 1, and an overflow pipe 14 is fixedly sleeved on the inner wall of the second fixing hole 22. Several flipping plates 15 are fixedly installed on the inner wall of the rotating cylinder 6. A fixed base frame 16 is fixedly installed on the bottom surface of the preliminary processing chamber 1, and a supporting base frame 17 is fixedly installed on the bottom surface of the secondary processing chamber 2. The supporting base frame 17 is fixedly installed with the industrial hot air blower 9, and a connecting frame 18 is fixedly installed between the fixed base frame 16 and the supporting base frame 17. An arc-shaped plate 19 is fixedly installed on one side of the interior of the secondary processing chamber 2, and the arc-shaped plate 19 extends five centimeters into the interior of the rotating cylinder 6.

[0027] In use, the industrial hot air blower 9 is started to generate hot air, which blows hot air into the interior of the secondary treatment chamber 2. The hot air rises along the arc plate 19 and enters the interior of the rotating cylinder 6, causing the air inside the secondary treatment chamber 2 and the rotating cylinder 6 to circulate. The high temperature improves the drying effect on the water glass sand. The hot and humid air inside the secondary treatment chamber 2 is discharged through the exhaust port 10. The water glass sand flows downward to the bottom of the rotating cylinder 6 and falls onto the top surface of the discharge hopper 11, and is discharged from the interior of the secondary treatment chamber 2 through the discharge hopper 11.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: Through the pre-treatment chamber 1, when the user needs water glass sand for dehydration, the mixture of water glass sand and (waste) water is conveyed into the interior of the pre-treatment chamber 1 through the feed pipe 13. The water glass sand will settle at the bottom of the pre-treatment chamber 1. The first drive motor 4 is started to drive the spiral blades 3 to rotate. The rotating spiral blades 3 push the water glass sand at the bottom of the pre-treatment chamber 1 upwards, and water flows through the gap between the spiral blades 3 and the pre-treatment chamber 1. The water flows out through the overflow pipe 14, thus initially separating the water glass sand. The water glass sand falls into the rotating cylinder 6 inside the secondary treatment chamber 2 through the guide hopper 5. The rotating cylinder 6 is started to drive the support frame 20 to rotate, which in turn drives the rotating cylinder 6 to rotate. Several filter screens 8 are installed on the outside of the rotating cylinder 6, and several flipping plates 15 are used to tumble the water glass sand. Because the rotating cylinder 6 is set at an incline, the water glass sand flows to the lower right, and the water flows out through the filter screens 8, falls to the bottom of the secondary treatment chamber 2, and is discharged through the liquid outlet pipe 12. When the industrial hot air blower 9 is activated, it generates hot air, which blows hot air into the secondary processing chamber 2. The hot air rises along the arc-shaped plate 19 and enters the rotating cylinder 6, causing airflow inside the secondary processing chamber 2 and the rotating cylinder 6, raising the temperature. The high temperature improves the drying effect on the water glass sand. The hot and humid air inside the secondary processing chamber 2 is discharged through the exhaust port 10. The water glass sand flows downward to the bottom of the rotating cylinder 6 and falls onto the top surface of the discharge hopper 11, from which it is discharged from the secondary processing chamber 2. Through the above design, the drying of the water glass sand is achieved. This device achieves highly efficient dewatering of water glass sand by combining preliminary and secondary treatments, significantly improving the dewatering effect and speed. Simultaneously, in the preliminary treatment chamber 1, the water glass sand is removed from the solid-liquid mixture, avoiding the filtration of large amounts of wastewater by the sand particles. Compared to existing technologies, this design reduces impurities adhering to the water glass sand, significantly improving the quality of the recycled water glass sand. This device not only solves the problem of sand accumulation obscuring the filter cap but also ensures the cleanliness of the sand particles, demonstrating high practicality and promotional value.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
