Description

Technical Field

[0001] The utility model relates to the technical field of coal slime recovery, in particular to a coal slime recovery and processing device. Background Art

[0002] Coal slime refers to the semi-solid substance formed by coal powder containing water, which is a product in the coal production process. Coal enterprises will produce a large amount of coal slime water during the coal washing process.

[0003] The coal slime recovery process is: coal slime water → coal slime concentrator concentration → coal slime filter pressing dehydration → coal slime discharge to the coal slime site. After sedimentation, the coal slime water is concentrated and filtered to obtain coal slime cake. When the existing coal slime water is precipitated, sedimentation reagents are added to accelerate the sedimentation of the coal slime water. However, the opening of the pipe for the sedimentation reagent is always in the sedimentation equipment. The added coal slime water sometimes surges over the opening of the pipe for the sedimentation reagent, resulting in coal slime attached to the pipe opening. Too much coal slime attached can easily cause the opening to become smaller and affect the discharge of reagents.

[0004] In view of this, we propose a coal slime recovery and processing device. Utility Model Content

[0032] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0033] Example 1: A coal slime recovery and processing device, see Figures 1 to 4 , including a sedimentation tank body 1, a liquid inlet channel 2 is arranged at the top liquid inlet end of the sedimentation tank body 1, and the liquid inlet channel 2 is connected to the coal slurry water delivery pipeline; a drainage channel 4 is arranged at the bottom liquid outlet end of the sedimentation tank body 1, and the drainage channel 4 is connected to the concentrated coal slurry water delivery pipeline after precipitation; and also includes a dosing channel 3 and a blocking structure 5;

[0034] The dosing channel 3 is arranged at the top pressurizing end of the sedimentation tank body 1; valves are arranged on the dosing channel 3, the liquid inlet channel 2 and the liquid discharge channel 4, and the dosing channel 3, the liquid inlet channel 2 and the liquid discharge channel 4 are independently controlled to open and close; the blocking structure 5 is arranged at the outlet end of the dosing channel 3;

[0035] The blocking structure 5 includes a fixed ring 501, a connecting rod 502, a movable ring 503 and a cover 505;

[0036] The fixed ring 501 is sleeved on the outlet end of the dosing channel 3; three connecting rods 502 are arranged in a ring array on the fixed ring 501; the movable ring 503 is sleeved on the dosing channel 3; wherein, one side of the movable ring 503 is fixedly connected to the inner ends of the three connecting rods 502; wherein, a spring 504 is sleeved on the connecting rod 502 between the movable ring 503 and the fixed ring 501; the two ends of the spring 504 are respectively fixedly connected to the movable ring 503 and the fixed ring 501, and the elastic coefficient of the spring 504 is selected and used by the technicians in this profession according to the actual situation; the cover 505 is fixedly arranged on the outer ends of the three connecting rods 502; wherein, the inner side of the cover 505 is sealed and matched with the outlet of the dosing channel 3.

[0037] The utility model has the advantages that the cover 505 seals the outlet end of the dosing channel 3 when no precipitation reagent is added by arranging a fixed ring 501, a connecting rod 502, a movable ring 503, a spring 504 and a cover 505, so that the dosing channel 3 will not contact the coal sludge water, thereby solving the problem that too much coal sludge attached to the opening of the pipeline may cause the opening to become smaller and affect the discharge of reagents.

[0038] Specifically, the spring 504 is in a compressed state, and the thrust generated by the compressed spring 504 causes the cover 505 to press against the outlet end of the dosing channel 3 . The cover 505 is opened only when pushed by the precipitation reagent solution sprayed out from the outlet end of the dosing channel 3 .

[0039] Furthermore, the movable ring 503 is located on the transverse section of the drug adding channel 3 ; the movable ring 503 moves stably on the transverse section of the drug adding channel 3 .

[0040] Furthermore, a sealing block 506 is fixedly provided in the middle of the inner side of the sealing cover 505, and the sealing block 506 is inserted and matched with the outlet end of the dosing channel 3; wherein, a sealing ring 507 is sleeved on the sealing block 506, and the outer ring wall of the sealing ring 507 contacts and cooperates with the inner cavity wall of the outlet end of the dosing channel 3.

[0041] The utility model provides the sealing block 506 and the sealing ring 507 , so that when the sealing cover 505 abuts against the outlet end of the dosing channel 3 , the sealing block 506 and the sealing ring 507 are correspondingly inserted into the outlet end of the dosing channel 3 , thereby further sealing the outlet of the dosing channel 3 .

[0042] It is worth noting that the outer ring of the insertion side of the sealing ring 507 is configured as an annular inclined surface, so that the insertion side of the sealing ring 507 is easier to insert into the outlet end of the dosing channel 3.

[0043] Working principle: When using the device of the utility model, the coal slurry water is introduced into the sedimentation tank body 1 through the liquid inlet channel 2. At this time, the inner side of the cover 505 is sealed with the outlet of the dosing channel 3, and the block 506 and the sealing ring 507 are correspondingly inserted into the outlet end of the dosing channel 3. After the coal slurry water is introduced, the pressurized precipitation reagent is added through the dosing channel 3, the block 506 moves outward under the impact of the precipitation reagent, the cover 505 is pushed outward, the connecting rod 502 drives the movable ring 503 to move outward, the spring 504 is further compressed, and the precipitation reagent liquid is discharged from the opened outlet of the dosing channel 3. The precipitation reagent liquid hits the block 506 and spreads and falls into the sedimentation tank body 1 to assist the precipitation of the coal slurry water. After the introduction of the precipitation reagent is stopped, under the action of the spring 504, the movable ring 503 drives the connecting rod 502 to move inward, and the block 506 and the cover 505 move inward until the block 506 and the sealing ring 507 are correspondingly inserted into the outlet end of the dosing channel 3. After precipitation, the concentrated coal slurry water obtained by precipitation is discharged through the drainage channel 4 and transported to the subsequent filter pressing process.

[0044] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
