Description

Technical Field

[0001] The utility model relates to the technical field of fly ash treatment, in particular to a water-washing and salt-separating device for garbage fly ash treatment. Background Art

[0002] Garbage fly ash is a hazardous waste with both heavy metal hazard characteristics and environmental persistent organic toxicity hazard characteristics. Usually, the fly ash needs to be pre-treated before it can be safely discharged. Fly ash washing is a commonly used fly ash treatment method at this stage. Fly ash washing technology uses water washing to wash the salt in the fly ash into the wastewater, and finally distills and crystallizes the obtained wastewater to precipitate mixed salt. At this time, the pollutants in the fly ash can be transferred to the mixed salt, so as to facilitate the fixed-point treatment of the pollutants.

[0003] When traditionally washing fly ash with water, the fly ash is usually directly placed into a washing tank for water washing and salt separation. Since the density of fly ash is relatively light, it usually floats on the liquid surface, resulting in uneven immersion of the fly ash, thus affecting the effect of salt separation.

[0004] Therefore, we propose a water-washing and salt-separating device for waste fly ash treatment in order to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to solve the problem that garbage fly ash floats on the liquid surface and is soaked unevenly due to its relatively light density.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a garbage fly ash treatment water washing and salt separation device, comprising a base and a column fixed on one side of the base, a water washing tank is installed on the top of the base, a mounting frame is provided on one side of the column, a first motor is installed on one end of the mounting frame, the output shaft of the first motor passes through the mounting frame and a rotating shaft is installed, the bottom end of the rotating shaft extends to the water washing tank where a filter plate is installed, a plurality of stirring plates are provided at the bottom of the filter plate, when the filter plate presses the garbage fly ash floating on the liquid surface into the inside of the liquid and rotates the filter plate, the garbage fly ash immersed below the liquid surface is stirred by the plurality of stirring plates at the bottom of the filter plate.

[0007] Furthermore: a second motor is installed on the top of the column, the output end of the second motor extends to the column and a screw is installed inside the column, a threaded seat is threadedly installed on the screw, and one side of the threaded seat passes through the column and is fixedly connected to the side wall of the mounting frame.

[0008] Further: the filter plate includes a mounting seat fixed at the bottom end of the rotating shaft and a fixing ring arranged coaxially with the mounting seat, and the outer surface of the mounting seat is equidistantly fixed with multiple fixing rods fixedly connected to the fixing ring along the circumferential direction, and a filter is fixed between adjacent fixing rods.

[0009] Furthermore: a plurality of the stirring plates are fixed on the outer surface of the mounting seat at equal intervals along the circumferential direction, a fixing seat is fixed on one end of the stirring plate away from the mounting seat, and the fixing seat is fixed on the bottom of the fixing ring.

[0010] Further: a sealing cover is threadedly installed at the opening on the top of the water washing tank, and the sealing cover is slidably installed on the rotating shaft up and down.

[0011] Further: a protrusion is fixed on the rotating shaft, and the protrusion is located between the filter plate and the sealing cover.

[0012] Furthermore: a drain outlet is provided at the lower part of the water washing tank, and a sealing plug is threadedly installed at the opening of the drain outlet.

[0013] Beneficial effects of the utility model:

[0014] The utility model provides a filter plate at the bottom of the rotating shaft. When the second motor drives the threaded seat to move downward through the screw rod, the threaded seat drives the filter plate to move downward through the mounting frame and the rotating shaft in turn. The filter plate can pressurize the garbage fly ash floating on the liquid surface downward, so that the garbage fly ash is completely immersed below the water level, thereby being able to fully immerse the garbage fly ash in the water level and evenly process the garbage fly ash, thereby improving the salt separation effect.

[0015] The utility model is provided with a stirring plate below the filter plate and a first motor at the top of the rotating shaft. During the process of the first motor driving the filter plate to rotate through the rotating shaft, the filter plate can drive a plurality of stirring plates to stir, so that the garbage fly ash can be stirred through the stirring plates, so that the garbage fly ash is fully in contact with the water level, and the salt separation effect is further improved.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0024] Embodiments of the present utility model:

[0025] A device for washing and salt separation of garbage fly ash for treating garbage fly ash comprises a base 1, a column 2 is fixed on one side of the base 1, and a washing tank 3 is fixed on the top of the base 1. By setting the washing tank 3, the garbage fly ash can be soaked, so that the washing tank 3 can be treated with salt separation. A sealing cover 12 is threadedly installed at the opening of the top of the washing tank 3. The setting of the sealing cover 12 plays a role of sealing the washing tank 3. The outer surface of the sealing cover 12 is equidistantly fixed with a plurality of handles 15 along the circumferential direction. The setting of the handles 15 facilitates the rotation of the sealing cover 12. A drain port 14 is opened at the lower part of the washing tank 3. The setting of the drain port 14 can discharge the used water in the base 1, and a sealing plug (not shown in the figure) is threadedly installed at the opening of the drain port 14; the setting of the sealing plug plays a role of sealing the drain port 14, so as to prevent the water in the washing tank 3 from flowing out through the drain port 14 during use.

[0026] A groove with a "convex" shape in cross section is opened on the column 2, and a second motor 9 is fixed on the top of the column 2. In order to facilitate the control of the speed of the second motor 9, the second motor 9 can be a servo motor, and the output shaft of the second motor 9 extends into the groove and a screw rod 10 is installed, and the bottom end of the screw rod 10 is rotatably connected to the inner bottom wall of the groove, and a threaded seat 11 is threadedly installed on the screw rod 10, and one end of the threaded seat 11 extends to the outside of the column 2 and a mounting frame 4 is installed, and the end of the mounting frame 4 away from the column 2 is installed with a first motor 5, and the output of the first motor 5 is connected to the bottom wall of the groove. The output shaft passes through the mounting frame 4 to install a rotating shaft 6, and the bottom end of the rotating shaft 6 passes through the sealing cover 12 to fix a mounting seat 71, and the outer surface of the mounting seat 71 is fixed with a plurality of fixing rods 73 equidistantly along the circumferential direction, and the ends of the plurality of fixing rods 73 away from the mounting seat 71 are fixedly connected to the same fixing ring 72. The setting of the fixing rods 73 plays a reinforcing role to prevent deformation, and a filter screen 74 is arranged between adjacent fixing rods 73, which can apply downward pressure to the garbage fly ash floating on the liquid surface so that the garbage fly ash is completely immersed in water.

[0027] The outer surface of the mounting seat 71 is fixed with a plurality of stirring plates 8 at equal intervals in the circumferential direction. Through the setting of the stirring plates 8, the garbage fly ash under the filter 74 can be stirred, so that the garbage fly ash and water are in full contact, and the salt separation effect is further improved. A fixing seat 81 is fixed at one end of the stirring plate 8 away from the mounting seat 71, and the fixing seat 81 is fixed to the outer surface of the fixing ring 72. Through the setting of the fixing seat 81, the stirring plate 8 is reinforced to prevent the stirring plate 8 from being deformed when used for a long time.

[0028] A protrusion 13 is fixed on the rotating shaft 6, and the protrusion 13 is located between the filter plate 7 and the sealing cover 12. Through the setting of the protrusion 13, when the mounting frame 4 drives the protrusion 13 to move through the rotating shaft 6, the protrusion 13 drives the sealing cover 12 to move upward, so that the sealing cover 12 can be opened from the top of the washing tank 3.

[0029] When the garbage fly ash is subjected to salt separation treatment, the sealing cover 12 needs to be opened from the top of the water washing tank 3 first, and then water and the garbage fly ash to be salted are added into the water washing tank 3, and finally the garbage fly ash is subjected to salt separation treatment.

[0030] When opening the sealing cover 12, first turn on the second motor 9. The output end of the second motor 9 rotates in the forward direction and drives the screw 10 to rotate. The screw 10 can drive the threaded seat 11 to move upward. The threaded seat 11 drives the rotating shaft 6 to move upward through the mounting bracket 4. The rotating shaft 6 drives the plurality of filter screens 74 to move upward. In the process, it can also drive the protrusion 13 to move upward. The sealing cover 12 can be opened from the top of the water washing tank 3 through the protrusion 13, so that the filter screen 74 and the stirring plate 8 can be taken out of the water washing tank 3.

[0031] Then, water and the garbage fly ash to be processed are added into the washing tank 3. Since some of the garbage fly ash has a relatively light density, it usually floats on the liquid surface.

[0032] The second motor 9 is turned on again, and the output end of the second motor 9 rotates in the opposite direction and drives the screw 10 to rotate, so that the screw 10 can drive the threaded seat 11 to move downward, and the threaded seat 11 drives the rotating shaft 6 to move downward through the mounting bracket 4. The rotating shaft 6 drives the plurality of filter screens 74 to move downward, and can also drive the protrusion 13 to move downward, so that the sealing cover 12 can slowly close at the opening of the water washing tank 3, and the sealing cover 12 is spirally rotated, so that the sealing cover 12 and the water washing tank 3 are tightly closed to prevent the water in the water washing tank 3 from being spilled to the outside during the salt separation process, and the plurality of filter screens 74 can pressurize the garbage fly ash floating on the liquid surface, so that the garbage fly ash floating on the liquid surface is completely immersed in the water, and then the first motor 5 is turned on again, and the output shaft of the first motor 5 drives the rotating shaft 6 to rotate, so that the rotating shaft 6 drives the plurality of stirring plates 8 to rotate at a high degree through the mounting bracket 71, and the garbage fly ash is stirred by the plurality of stirring plates 8, so that the garbage fly ash is fully in contact with the water, thereby completing the work of salt separation of the garbage fly ash.
