Description

A new high-efficiency thickening device for treating coal slurry water Technical Field

[0001] This utility model relates to the fields of wastewater treatment and mineral processing technology, and in particular to a new high-efficiency concentration device for treating coal slurry water. Background Technology

[0002] During the settling process of coal slurry, the free settling zone exhibits the fastest settling velocity, almost directly proportional to the settling time. This is the rapid dewatering stage under gravity, characterized by a very high settling velocity, also known as the free settling stage. A settling area corresponding to this velocity is sufficient to process large quantities of coal slurry, removing significant amounts of free water, without requiring specific volume. In the interference settling stage, the settling velocity decreases significantly, marking the transition from free settling to compression settling. During this stage, the settling velocity is very slow, requiring substantial volume and depth to provide sufficient settling time and compression layer pressure. Achieving suitable concentrations in production necessitates the use of large thickening equipment, which occupies a large area and has a high ceiling, resulting in high costs.

[0003] Based on the above description, to reduce the cost of equipment, the footprint and height of the equipment must be reduced in order to reduce the amount of manufacturing materials required.

[0004] Therefore, this utility model provides a new high-efficiency concentration device for treating coal slurry water. Summary of the Invention

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] As shown in Figures 1-7, this embodiment provides a technical solution: a new high-efficiency thickening device for treating coal slurry water, including an inclined plate thickener 1 and a deep cone thickener 2. A connecting pipe 3 is provided between the inclined plate thickener 1 and the deep cone thickener 2. A first discharge pipe 4 is provided at the bottom of the inclined plate thickener 1, and a second discharge pipe 5 is provided at the bottom of the deep cone thickener 2. A control valve is provided on one side of the connecting pipe 3, the first discharge pipe 4, and the second discharge pipe 5. A vibration device 11 is installed on the outer surface of the deep cone thickener 2. An auxiliary mounting plate 8 is fixedly connected to the inner wall of the deep cone thickener 2. A pump body 12 is fixedly installed on the top of the auxiliary mounting plate 8. The inlet and outlet ends of the pump body 12 are respectively connected to an inlet pipe 9 and an outlet pipe 10. A detachable inclined plate structure 6 is provided on the top of the inclined plate thickener 1. The detachable inclined plate structure 6 includes a rectangular frame 61. One side of the rectangular frame 61 is connected to... One side of the inclined plate thickener 1 is fixedly connected, and a rectangular clamping block 63 is clamped to the inner wall of the rectangular clamping frame 61; a filter water outlet structure 7 is set on the top of the inclined plate thickener 1, the filter water outlet structure 7 includes a drain trough pipe 71, one side of the drain trough pipe 71 is fixedly connected to one side of the inclined plate thickener 1, and a drain hole 72 is opened at the bottom of the drain trough pipe 71. According to the settling characteristics of coal slurry, the scheme of combining the inclined plate thickener 1 and the deep cone thickener 2 is adopted, which makes the most reasonable use of the advantages of the two devices and avoids the disadvantages of the two devices, so that the cost and floor space of the entire thickening system are greatly reduced. A vibration device 11 is installed on the outer wall or inside of the deep cone thickener 2. The vibration force can destroy the stability of the compression layer, increase the compression speed of the coal slurry by 3 to 5 times, greatly reduce the external size of the deep cone thickener 2, and further reduce the cost and floor space.

[0028] Furthermore, as shown in Figures 3 and 4: A rectangular ring plate 66 is fixedly connected to the top of the rectangular clamping block 63, and an installation plate 67 is fixedly connected to the inner wall of the rectangular ring plate 66. A circular insertion hole 62 is opened on the inner wall of the rectangular clamping frame 61. A threaded insertion rod 64 is fixedly connected to the bottom of the rectangular clamping block 63, and a first fixing nut 65 is threaded to the bottom end of the threaded insertion rod 64. A rectangular clamping groove 68 is opened at the bottom of the installation plate 67, and a rectangular clamping block 69 is clamped to the inner wall of the rectangular clamping groove 68. An inclined filter plate 612 is set at the bottom of the rectangular clamping block 69. Under the action of the rectangular clamping block 63 and the rectangular clamping frame 61, the rectangular ring plate 66 and the installation plate 67 can be disassembled and assembled. Furthermore, under the action of the rectangular clamping groove 68 and the rectangular clamping block 69, the inclined filter plate 612 can be disassembled and assembled. This allows for convenient individual disassembly and assembly of the inclined filter plate 612, and also allows for the replacement and maintenance of individual inclined filter plates 612.

[0029] The above solution also has the problem that the rectangular locking block 69 and the rectangular locking groove 68 are fixed by friction, which will lead to overall instability, as shown in Figure 3. In this solution, the inner wall of the mounting plate 67 is provided with a first insertion hole 610, and the inner wall of the rectangular locking block 69 is provided with a second insertion hole 611. The inner walls of the first insertion hole 610 and the second insertion hole 611 are fitted with threaded plug rods 613. One end of the threaded plug rod 613 is threadedly connected to a second fixing nut 614. Under the action of the threaded plug rod 613, the rectangular locking block 69 and the mounting plate 67 can be fixed together with the first insertion hole 610 and the second insertion hole 611.

[0030] The above solution also has the problem that the clear water at the top of the inclined plate thickener 1 contains large particulate impurities, which affects the quality of the clear water output. As shown in Figures 5-7, the bottom of the drain pipe 71 is provided with a first rectangular slot 73, the top of the drain pipe 71 is provided with a second rectangular slot 74, and the top of the drain pipe 71 is provided with a threaded locking hole 710. A rectangular insert plate 75 is inserted into the inner wall of the first rectangular slot 73 and the second rectangular slot 74. A filter plate 77 is fixedly connected to the inner wall of the rectangular insert plate 75. A rectangular baffle 76 is fixedly connected to the top of the rectangular insert plate 75. A rectangular block 78 is fixedly connected to one side of the rectangular baffle 76. A threaded locking rod 79 is threadedly connected to the inner wall of the rectangular block 78. Under the action of the first rectangular slot 73 and the second rectangular slot 74, the rectangular insert plate 75 can be fixed. Under the action of the threaded locking rod 79 and the threaded locking hole 710, the rectangular insert plate 75 can be fixed. Under the action of the filter plate 77, the water can be filtered. Then, the water can be drained from the drain pipe 71.

[0031] Working principle:

[0032] As shown in Figure 1-7:

[0033] In use: The overlapping inclined filter plates 612 are used to increase the settling area, so that a small footprint can provide a large settling area. Therefore, the equipment volume is very small. The inclined plate thickener 1 is most suitable for rapid and efficient dewatering in the settling stage and obtaining coal slurry in the interference settling stage (i.e., the underflow of the inclined plate thickener 1). At this time, after most of the free water is removed by the inclined plate thickener 1 and the volume of coal slurry is greatly reduced, it is necessary to further concentrate it to a high concentration of coal slurry. A large volume and height are required to ensure the compression time and extrusion pressure. In this stage, a deep cone thickener 2 with a vibration device 11 is used for efficient compression.

[0034] The deep cone thickener 2 with vibration device 11 is characterized by installing vibration device 11 on the outer wall of the deep cone thickener 2 or inside its coal slurry. Vibration force is used to disrupt the stability of the compression layer in the coal slurry, which can reduce the natural compression time by 3 to 5 times compared with the natural compression time without vibration force, thereby reducing the volume required for coal slurry compression by 3 to 5 times.

[0035] The underflow coal slurry from the inclined plate thickener 1 enters the upper part of the deep cone thickener 2 for compression, and the stability of the coal slurry compression layer is disrupted by the vibration device 11, greatly increasing the compression speed. The overflow from the deep cone thickener 2 returns to the inclined plate thickener 1 to compensate for the disadvantage of the deep cone thickener 2 having a small settling area, which may lead to overflow and turbidity. However, the concentration of this overflow is already very low and falls within the free settling range of the inclined plate thickener 1.

[0036] When installing the inclined filter plate 612, the rectangular locking block 69 is inserted into the inner wall of the rectangular locking groove 68, the threaded plug rod 613 is inserted into the first insertion hole 610 and the second insertion hole 611, the second fixing nut 614 is fixed to the threaded plug rod 613, the rectangular locking block 63 is snapped into the inner wall of the rectangular frame 61, the threaded plug rod 64 is inserted into the inner wall of the round insertion hole 62, and then the inner wall of the first fixing nut 65 is secured, thus allowing the inclined filter plate 612 to be installed.

[0037] When it is necessary to filter the clean water at the top of the inclined plate thickener 1, the rectangular insert plate 75 is inserted into the inner wall of the first rectangular slot 73 and the second rectangular slot 74, and the threaded clamp rod 79 is fixed with the threaded clamp hole 710, so that large particulate impurities inside the clean water can be filtered.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
