Description

Technical Field

[0001] The invention relates to the technical field of coal settling pools, in particular to a circular coal settling pool device with coal suction and drainage functions. Background Art

[0002] Coal settling pool is a sedimentation facility used in the coal industry. It mainly uses the principle of gravity sedimentation to treat the water containing coal particles and impurities generated during coal processing, so that the coal particles are settled at the bottom of the pool, thereby achieving solid-liquid separation. It is usually used to store and burn coal to generate fuel for power generators. Due to the high moisture content of coal, a certain amount of silt and debris may accumulate at the bottom of the pool, so it is very important to clean the coal settling pool regularly.

[0003] A Chinese invention patent with publication number CN109200636B discloses a sedimentation tank for treating high-concentration wastewater from coal chemical industry, including a tank body, a plurality of first drain pipes are arranged at the upper end of the tank body, a working pipe is fixedly and vertically arranged at the bottom of the tank body, the height of the working pipe is higher than the tank body, a third drain pipe and a second drain pipe extending downward are arranged in sequence near the water outlet of the first drain pipe, the third drain pipe is farther away from the water outlet of the first drain pipe than the second drain pipe, the water outlet of the third drain pipe is lower than the water outlet of the second drain pipe, the second drain pipe and the third drain pipe are both provided with electromagnetic switch valves, and the working pipe is provided with 3 pressure sensors electrically connected to the electromagnetic switch valves in an array along its height direction; the situation that the sewage in the sedimentation tank fluctuates greatly due to the large height difference between the sewage surface and the drain pipe is effectively avoided, and the sedimentation process is ensured to be completed smoothly.

[0004] In addition, since most sedimentation tanks are rectangular, the coal particles are accumulated in a relatively dispersed manner. When the coal sewage enters the sedimentation tank, it is generally settled by the gravity of the coal particles themselves. However, due to the presence of oil stains on the top of the coal water sedimentation tank, an oil film will be formed on the water surface. If not handled in time, this oil film will hinder the oxygen in the air from dissolving into the coal sewage. The lack of oxygen will prevent the oxidation process from proceeding smoothly, resulting in a reduction in the iron hydroxide (Fe(OH)3) colloid formed by iron ions. The iron hydroxide colloid has the function of adsorbing suspended particles, thereby reducing the precipitation efficiency of suspended particles in the coal water. Therefore, the Chinese invention patent CN109200636B discloses a computer vision-based road blind corner traffic warning device, which makes it impossible for the coal suction machine to effectively absorb the coal particles in the corner and to clean the oil stains on the sewage surface in time, resulting in a decrease in the precipitation rate of suspended particles.

[0019] Compared with the prior art, the present invention provides a circular coal sinking pool device with coal suction and drainage functions, which has the following beneficial effects:

[0022] 3. The coal sewage is aerated through an aeration pipe, so that the flow rate of the coal sewage is increased in the process of bubbles flowing to the water surface, and the contact frequency between the suspended particles in the coal sewage and the generated iron hydroxide colloid is increased, thereby improving the adsorption effect of the iron hydroxide colloid on the suspended particles.

A slide groove 57 is provided on the upper surface of the coal suction machine 56, and an arc-shaped groove 58 is provided on the bottom of the inner cavity of the sedimentation tank 1. The size of the arc-shaped groove 58 is matched with the size of the lower surface of the coal suction machine 56. The arc-shaped groove 58 is an arc-shaped groove that is wide at the top and narrow at the bottom. Through the arc-shaped groove 58, coal particles can reach the bottom of the sedimentation tank 1 through the action of gravity, and then a large number of coal particles will gather in the middle recessed position, thereby improving the efficiency of the coal suction machine 56 in absorbing coal particles.

[0039] Furthermore, the speed-up mechanism 6 includes a second fixed rod 61 symmetrically fixedly connected to the inner wall of the sedimentation tank 1, the inner end of the second fixed rod 61 is fixedly connected to an aeration pipe 62, the lower surface of the aeration pipe 62 is arranged in an annular array and is fixedly connected to a plurality of aeration heads 63, the lower surface of the aeration pipe 62 is symmetrically fixedly connected to a telescopic rod 64, and there is an electrical connection between the telescopic rod 64 and an external control device, the bottom end of the telescopic rod 64 is fixedly connected to an annular plate 65, the annular plate 65 slides inside the slide groove 57, the upper surface of the annular plate 65 is arranged in an annular array and is fixedly connected to a plurality of piston blocks 66, an oil absorption plate 67 is fixedly connected to the top inner wall of the sedimentation tank 1, and the material of the oil absorption plate 67 is polypropylene fiber. Aeration through the aeration pipe 62 enables the coal particles in the coal water to fully contact with oxygen, and at the same time, the aeration head 63 is blocked by the piston block 66, thereby preventing the aeration head 63 from being effectively aerated after being blocked.

[0040] Furthermore, the speed-up mechanism 6 also includes a scraper 68 symmetrically fixedly connected to the outer wall of the output end of the drive motor 54, a slide bar 612 is fixedly connected between the two top ends of the scraper 68, a slider 69 is slidably connected to the outer wall of the slider 612, and an oil scraper groove plate 610 is fixedly connected to the bottom end of the slider 69, and the oil scraper groove plate 610 penetrates and slides on the outer wall of the scraper 68, and a strong magnetic block 611 is symmetrically fixedly connected to the upper surface of the oil scraper groove plate 610, and the slide bar 612 is fixedly connected to the outer wall of the scraper 68. A spring 613 is sleeved on the outer wall, and the two ends of the spring 613 are fixedly connected to the scraper 68 and the slider 69 respectively. A strong magnetic block 2 614 is symmetrically fixedly connected to the upper surface of the sedimentation tank 1. The magnetic poles of the strong magnetic block 1 611 and the strong magnetic block 2 614 are opposite. The strong magnetic block 2 614 and the strong magnetic block 1 611 are on the same horizontal plane. The oil stains on the outer wall of the scraper 68 are intermittently scraped off by the oil scraper groove plate 610, so that the oil stains can be fully absorbed by the oil absorption plate 67.

[0041] The following is the working process and principle of the above embodiment:

[0042] The initial state is as follows: the telescopic rod 64 is in an unretracted state, and the sliding rod 612 is in an unretracted state.

[0043] The working steps are as follows:

[0044] The operator directs the sewage into the conical nozzle 44 through the water pipe 43, so that the sewage inside the conical nozzle 44 is sprayed toward the lower surface of the circular baffle 53 through the cylinder 51, so that the sewage moves toward the inside of the sedimentation tank 1 under the isolation of the circular baffle 53, so that the coal particles inside the sewage flow to the bottom of the sedimentation tank 1 synchronously, and at the same time, the ultraviolet lamp 3 fixedly connected to the inner wall of the sedimentation tank 1 emits ultraviolet light, so that the ultraviolet light sterilizes and disinfects the sewage inside the sedimentation tank 1.

[0045] When the surface of the coal sewage is on the same level as the oil absorption plate 67, the float valve provided inside the water pipe 43 starts to block the water outlet of the water pipe 43, and the operator controls the output end of the drive motor 54 to start to rotate slowly through the external control device. During the slow rotation of the output end of the drive motor 54, the drive motor 54 drives the scraper 68 to rotate synchronously, so that the scraper 68 scrapes the oil on the surface of the sewage, so that the oil adheres to the outer wall of the scraper 68. When the scraper 68 drives the strong magnetic block 1 611 to move to the same level as the strong magnetic block 2 614 through the slider 69 and the scraper groove plate 610, the strong magnetic block The second magnetic block 614 magnetically attracts the strong magnetic block 1 611, so that the strong magnetic block 1 611 drives the scraper groove plate 610 to slide on the outer wall of the scraper plate 68 toward the side close to the strong magnetic block 2 614, so that the oil on the outer wall of the scraper plate 68 is scraped off during the movement of the scraper groove plate 610, so that the oil enters the interior of the scraper groove plate 610. During the movement of the scraper groove plate 610, the scraper groove plate 610 drives the slider 69 to slide on the outer wall of the slide rod 612 toward the side close to the strong magnetic block 2 614, so that the slider 69 squeezes the slide rod 612 toward the side close to the strong magnetic block 2 614, so that the slide rod 612 contracts, thereby The oil scraper plate 610 drives the oil to move toward the side close to the oil absorption plate 67, so that the oil is absorbed after contacting the oil absorption plate 67. When the output end of the drive motor 54 drives the scraper plate 68 to continue to rotate, the strong magnetic block 1 611 is no longer in the same horizontal plane with the strong magnetic block 2 614, so that the slider 69 slides toward the side close to the drive motor 54 under the elastic action of the slide bar 612, so that the slider 69 drives the oil scraper plate 610 and the strong magnetic block 1 611 to slide toward the side close to the drive motor 54 synchronously, so that the oil scraper plate 610 moves to the initial position, and then drives the scraper plate 68 to rotate through the drive motor 54, so that the oil scraper plate 61 0 moves intermittently under the magnetic attraction of the strong magnetic block 1 611 and the strong magnetic block 2 614, so that the oil stains are intermittently contacted with the oil absorption plate 67 and absorbed. The scraper 68 is used to rotate the oil stains to prevent the oil stains from being attached to the water surface for a long time, resulting in the lack of oxygen in the coal sewage, and the iron ions in the coal sewage are prevented from being converted into iron hydroxide, thereby ensuring that the suspended particles in the coal sewage can be effectively adsorbed and the sedimentation rate of the suspended particles is increased. The oil stains on the outer wall of the scraper 68 are scraped off by the oil scraper groove plate 610 and the oil stains can be quickly contacted with the oil absorption plate 67, thereby improving the absorption efficiency of the oil absorption plate 67 for the oil stains.

[0046] While the coal particles are being absorbed, the sewage enters the interior of the drain pipe 45 through the filter plate set on the top of the drain pipe 45, and then the sewage enters the interior of the drain pipe 45 through the drain pipe 45 to be gathered, and finally discharged under the filtering action of the filter net 47, and then enters the next filtering stage.

[0047] After the oil stains on the top of the coal sewage are cleaned, the operator controls the aeration pipe 62 through the external control device to spray bubbles through the aeration head 63, so that the bubbles stir the coal sewage during the upward movement, so that the coal sewage frequently contacts the oxygen in the bubbles, thereby increasing the oxygen content in the coal sewage. Then, the operator controls the telescopic rod 64 to contract through the external control device, so that the telescopic rod 64 drives the piston block 66 through the annular plate 65 to seal the aeration head 63.

[0048] Subsequently, the heavier coal particles in the sewage settle to the bottom of the sedimentation tank 1 under the action of their own gravity. When the coal particles move to the bottom of the sedimentation tank 1, the coal particles are guided by the arc-shaped groove 58 to move to the middle of the arc-shaped groove 58, so that the coal particles accumulate in the middle of the arc-shaped groove 58. At the same time, in the process of slow rotation of the output end of the driving motor 54, the output end of the driving motor 54 drives the fixed rod 55 to rotate synchronously counterclockwise, so that the fixed rod 55 drives the coal suction machine 56 to rotate synchronously counterclockwise, and at the same time, the particles accumulated in the middle of the arc-shaped groove 58 are collected. The grooves set by the arc-shaped groove 58 help the coal particles to accumulate at the bottom of the arc-shaped groove 58 after sedimentation, which has the effect of gathering the coal particles. At the same time, the coal particles are absorbed by the rotating coal suction machine 56, avoiding the problem that the coal particles at the corners of the sedimentation tank 1 cannot be effectively absorbed, thereby improving the collection efficiency of the coal particles.
