[0002] Coal chemical industry waste residue, flue gas desulfurization gypsum, etc. are collectively referred to as coal-based solid waste. At present, coal-based solid waste is still mainly used for producing building materials in small amounts and stockpiling in large amounts. During the production and use of coal, a large amount of solid waste such as coal gangue, fly ash, and gasification slag will be generated. During the treatment process of multi-source coal-based solid waste, generally, steps such as flushing, dehydration, drying, and screening are required.

[0003] When flushing coal-based solid waste, after the flushing is completed, the coal-based solid waste needs to be dehydrated, dried, and screened. In the prior art, multiple treatments are required to complete the treatment process of coal-based solid waste. However, due to the different sizes of coal-based solid waste, it will bring inconvenience to the treatment work during the treatment process. During the screening process of coal-based solid waste using screening equipment, generally only large multi-source coal-based solid waste will be screened out. There are still smaller particles of multi-source coal-based solid waste and impurities in the small multi-source coal-based solid waste, and the screening effect is not good, affecting the screening quality, and thus affecting the subsequent treatment.

Specific embodiments

[0022] The following further describes the present utility model in conjunction with embodiments.

[0023] Please refer to Figures 1-4 , the present utility model provides a multi-stage dehydration and screening treatment device for coal-based solid waste, including a tank body 1, a feed pipe 2, a drying mechanism 3, a screening mechanism 4, a discharge pipe 5 and a water outlet pipe 6. The feed pipe 2 is fixedly connected to the middle part above the tank body 1. The drying mechanism 3 is arranged outside the tank body 1. The screening mechanism 4 is arranged inside the tank body 1. The discharge pipe 5 is fixedly connected to the left side of the bottom surface of the tank body 1. The water outlet pipe 6 is fixedly connected to the right side of the bottom surface of the tank body 1.

[0024] The screening mechanism 4 is composed of a motor 401, a connecting shaft 402, a third screening frame 403, a second screening frame 404, a first screening frame 405, a push plate 406 and a discharge assembly 407. The motor 401 is fixedly connected to the middle part of the bottom surface of the tank body 1. The connecting shaft 402 is connected to the output end of the motor 401. The third screening frame 403, the second screening frame 404 and the first screening frame 405 are respectively fixedly connected to the outer middle lower part, the middle part and the upper part of the connecting shaft 402 in sequence.

[0025] Further, as shown in Figure 1 , Figure 2 and Figure 3 , it is specifically noted that the opening sizes of the top surfaces of the third screening frame 403, the second screening frame 404 and the first screening frame 405 decrease in sequence, and discharge assemblies 407 are provided on the bottom surfaces.

[0026] Further, as shown in Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically stating that the push plate 406 is fixedly connected to the lower part of the outside of the connecting shaft 402, and the bottom surface of the push plate 406 is in contact with the inner bottom surface of the tank body 1.

[0027] Furthermore, as shown in Figure 3 and Figure 4 it is worth specifically stating that the discharging assembly 407 is composed of a cylinder 4071, a protection box 4072 and a baffle 4073. The cylinder 4071 is fixedly connected to the bottom surface of the screening frame. The protection box 4072 is sleeved on the outside of the cylinder 4071. The baffle 4073 is fixedly connected to the output end of the cylinder 4071. A discharging port 4074 is provided on the bottom surface of the screening frame, and sliding grooves are provided on both sides of the discharging port 4074. A sliding strip is provided on the top surface of the baffle 4073 and is slidably connected to the inside of the sliding groove. The size of the baffle 4073 is larger than the size of the discharging port 4074;

[0028] The cylinder 4071 drives the baffle 4073 to slide, opening the blocked discharging port 4074, so that the small particle coal-based solid waste inside falls onto the bottom surface of the tank body 1, facilitating the output of the coal-based solid waste.

[0029] According to the above working process, it can be seen that: through the arranged screening mechanism 4, the coal-based solid waste entering the inside of the tank body 1 through the feed pipe 2 can be screened. The motor 401 drives the connecting shaft 402 to rotate, thereby driving the third screening frame 403, the second screening frame 404 and the first screening frame 405 to rotate. While dewatering, the coal-based solid waste that can pass through the screening frame is thrown out and falls into the next screening frame to complete the screening, improving the efficiency of dewatering and screening.

[0030] Furthermore, as shown in Figure 1 , Figure 2 and Figure 3 it is worth specifically stating that the drying mechanism 3 is composed of a hot air blower 301, a first air supply pipe 302, a vertical pipe 303, an air outlet pipe 304 and a second air supply pipe 305. The hot air blower 301 is arranged on the right side of the tank body 1. The first air supply pipe 302 is fixedly connected to the output end of the hot air blower 301. The vertical pipes 303 are symmetrically arranged around the outside of the tank body 1. The air outlet pipes 304 are uniformly fixedly connected to one side of the vertical pipes 303, and the other ends of the air outlet pipes 304 extend into the inside of the tank body 1.

[0031] Furthermore, as shown in Figure 1 , Figure 2 and Figure 3 it is worth specifically stating that the right vertical pipe 303 is communicated with one end of the first air supply pipe 302, and the second air supply pipe 305 is fixedly connected between the vertical pipes 303;

[0032] Start the hot air blower 301. The hot air is input into the interior of the vertical pipe 303 through the first air supply pipe 302, and then into the interior of the tank body 1 through the air outlet pipe 304 to dry the coal-based solid waste inside and improve the dehydration effect.

[0033] This solution has the following working process: When in use, the water-bearing coal-based solid waste is input into the interior of the first screening frame 405 through the same-specification feed pipe 2. Then, start the motor 401 to drive the connecting shaft 402 to rotate, thereby driving the third screening frame 403, the second screening frame 404, and the first screening frame 405 to rotate, and shake the coal-based solid waste inside the first screening frame 405. The water is thrown out under the action of centrifugal force. At the same time, the medium-sized coal-based solid waste is thrown into the interior of the second screening frame 404 through the sieve holes of the first screening frame 405. Similarly, the small-sized coal-based solid waste is thrown into the interior of the third screening frame 403 through the sieve holes of the second screening frame 404, and the extremely small-sized coal-based solid waste falls onto the bottom surface of the tank body 1 through the sieve holes of the third screening frame 403. By controlling the forward and reverse rotation of the motor 401, the third screening frame 403, the second screening frame 404, and the first screening frame 405 can be driven to rotate forward and backward, so as to better drive the coal-based solid waste to vibrate and screen. The water body also falls onto the inner wall of the tank body 1 through the second screening frame 404 and the third screening frame 403 in sequence, and then flows into the bottom surface of the tank body 1, and finally flows out through the water outlet pipe 6; While screening, start the hot air blower 301. The hot air is input into the interior of the vertical pipe 303 through the first air supply pipe 302, and then into the interior of the tank body 1 through the air outlet pipe 304 to dry the coal-based solid waste inside and improve the dehydration effect; Then open the discharge pipe 5. By rotating the push plate 406, the extremely small-sized coal-based solid waste on the bottom surface of the tank body 1 is pushed and output through the discharge pipe 5. Then control the air cylinder 4071 below the third screening frame 403 to drive the baffle 4073 to slide, and open the blocked discharge port 4074, so that the small-sized coal-based solid waste inside falls onto the bottom surface of the tank body 1 and is output through the discharge pipe 5. The same operation can be used to output the coal-based solid waste inside the second screening frame 404 and the first screening frame 405 in sequence, completing the dehydration and screening process, which is convenient for subsequent operations.

[0034] In summary: Through the provided screening mechanism 4, the coal-based solid waste entering the interior of the tank body 1 through the feed pipe 2 can be screened. By driving the connecting shaft 402 to rotate through the motor 401, the third screening frame 403, the second screening frame 404, and the first screening frame 405 are driven to rotate. While dehydrating, the coal-based solid waste that can pass through the screening frame is thrown out and falls into the next screening frame to complete the screening, improving the efficiency of dehydration and screening; Through the provided drying mechanism 3, hot air can be conveyed to the periphery inside the tank body 1 to dry the coal-based solid waste inside, and then better complete dehydration, ensuring the dryness of the coal-based solid waste, which is convenient for subsequent processing and improving the processing effect of the device.
