Description

Technical Field

[0001] This utility model relates to the field of purification device technology, and more specifically to a centrifugal purification device for coal ash water. Background Technology

[0002] In the process of generating electricity from coal, coal ash water is wastewater formed during combustion and transportation. It contains a high concentration of suspended solids and does not meet water quality standards. If discharged directly, it will directly pollute water bodies, soil, and air, causing environmental pollution. Therefore, it needs to be purified to separate the suspended solids in the coal ash water. Currently, multi-stage sedimentation is often used to separate the coal ash water. However, the separation speed of natural sedimentation is slow and requires a lot of time. If the sludge is not discharged in time, it will accumulate and float to the surface, causing secondary pollution and hindering the purification of the coal ash water. Utility Model Content

[0028] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0029] like Figure 1-4 As shown, a centrifugal purification device for coal ash water includes:

[0030] Tank 1, with an inlet 21 at one end and an outlet 13 at the other end;

[0031] Fixed plate 50, fixed plate 50 is installed inside tank body 1;

[0032] Purification unit 5 is installed inside tank 1. Purification unit 5 includes a diversion column 56, a fixed plate 50, and a filter cover 501 rotatably installed on the fixed plate 50. The fixed plate 50 is snapped onto tank 1. The diversion column 56 is installed on the filter cover 501 and is located directly below the water inlet 21.

[0033] The filter cover 501 has an installation groove 52, and a filter plate 51 is installed on the installation groove 52;

[0034] Collection hood 16 is disposed inside tank 1 and located directly below filter hood 501;

[0035] The drive motor 31 is located at the end of the tank body 1, and the output end of the drive motor 31 is equipped with a transmission rod 32 that cooperates with the filter cover 501. The top cover 2 and the diversion cover 14 are both equipped with diversion pipes 17, which further improves the guiding effect of coal ash water and allows the water flow to fully impact the diversion column 56.

[0036] Specifically, when filtering coal ash water, the coal ash water flows into the tank 1 through the inlet 21 and flows onto the diversion column 56. At the same time, the drive motor 31 drives the transmission rod 32 to rotate, so that the diversion column 56 and the filter cover 501 rotate synchronously. Under the action of centrifugal force, the water is filtered and purified through the filter plate 51. The impurities are stored along the filter cover 501 into the collection cover 16 to quickly complete the filtration of coal ash water. The model of the drive motor 31 is GH18. Furthermore, the fixed plate 50 is fixedly connected to the filter cover 501, and the filter cover 501 is rotatably connected to the fixed plate 50. When the filter cover 501 rotates, the diversion column 56 rotates synchronously with the filter cover 501. The collection cover 16 is fixed to the tank 1 and fits against the filter cover 501 to support the rotation of the filter cover 501.

[0037] As a further embodiment of this utility model, the tank 1 includes a lower tank 12, an upper tank 11, and a top cover 2 disposed at one end of the upper tank 11. The upper tank 11 and the lower tank 12 cooperate with each other. Both the upper tank 11 and the lower tank 12 are provided with a filter cover 501 and a filter plate 51. The pore size of the filter plate 51 in the upper tank 11 is larger than that in the lower tank 12. The upper tank 11 and the lower tank 12 are connected by bolts. The water outlet 13 is disposed on the lower tank 12, and the top cover 2 is disposed on the upper tank 11. When the coal ash water enters the upper tank 11, it undergoes primary purification through the filter cover 501 in the upper tank 11 to filter out larger impurities in the coal ash water. Subsequently, it flows into the lower tank 12 to undergo secondary purification through the filter cover 501 in the lower tank 12 to improve the purification effect of the coal ash water.

[0038] As a further embodiment of this utility model, a flow guide hood 14 is provided on the tank body 1, and a flow divider 56 is provided directly below the flow guide hood 14. The flow divider 56 has a flow divider groove 57 arranged in a circular array on the flow divider 56, and a spiral blade 55 connected to the flow divider groove 57 is provided on the flow divider 56. When the coal ash water enters the tank body 1 from the inlet 21, it will flow onto the flow divider groove 57 and slide down along the flow divider groove 57 onto the spiral blade 55. At this time, the flow divider 56 is in a rotating state, so that water and impurities adhere to the filter plate 51. The water will flow through the filter holes on the filter plate 51 to the outlet 13, while the impurities will adhere to or fall onto the first end face 58, thereby completing the filtration and purification of the coal ash water.

[0039] As a further embodiment of this utility model, the filter cover 501 is provided with a first end face 58 and a second end face 59. The first end face 58 is provided with a drain hole, and the second end face 59 is provided with a discharge port. The discharge port is connected to the collection cover 16. When purifying coal ash water, its impurities will adhere to the filter plate 51, and a small amount of impurities will fall onto the first end face 58 and remain on the first end face 58 for a period of time to drain. Subsequently, the impurities will slide down onto the second end face 59 under the action of centrifugal force and flow down along the second end face 59 into the collection cover 16.

[0040] As a further embodiment of this utility model, an arc-shaped protrusion 591 is provided on the first end face 58. The arc-shaped protrusion 591 is used to increase the time for impurities to remain on the first end face 58, so that the water in the impurities flows through the drain hole to the collection cover 16, and then flows through the collection cover 16 to the outlet 13. The collection cover 16 is provided with multiple drain ports, and the diameter of the drain ports is smaller than the diameter of the filter plate 51.

[0041] As a further embodiment of this utility model, the first end face 58 is higher than the second end face 59, and an inclined platform is provided between the first end face 58 and the second end face 59. When the coal ash water is purified, the impurities in the coal ash water will fall onto the first end face 58. At this time, as the filter cover 501 rotates, under the action of centrifugal force, the impurities will fall along the inclined belt onto the second end face 59, so as to be stored in the collection cover 16 through the discharge trough.

[0042] As a further embodiment of this utility model, a cylinder 53 is provided on the fixed disk 50, and a scraper 54 is provided on the output shaft of the cylinder 53. After filtering for a long time, a large amount of impurities will be attached to the filter plate 51. At this time, the cylinder 53 retracts so that the scraper 54 fits against the filter plate 51. When the filter cover 501 rotates, the scraper 54 scrapes the impurities to improve the filtration effect of the filter plate 51.

[0043] As a further embodiment of this utility model, a support plate 15 is provided on the tank body 1, and the collection cover 16 is fixed to the tank body 1 by the support plate 15. There is a gap between the collection cover 16 and the tank body 1. When the coal ash water is purified, the purified and filtered water flows through the filter plate 51 from the gap between the collection cover 16 and the tank body 1 to the end of the tank body 1, and then flows out from the outlet 13. At least three support plates 15 are provided to support the collection cover 16 and not to hinder the flow of purified water.

[0044] As a further embodiment of this utility model, a top cover 2 is provided on the tank body 1, and a sealing element, which is a rubber sealing ring, is provided between the top cover 2 and the tank body 1 to improve the sealing performance between the top cover 2 and the tank body 1. At the same time, a sealing ring is provided between the upper tank body 11 and the lower tank body 12.

[0045] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
