Description

Technical Field

[0001] This utility model relates to the field of fly ash separation technology, specifically a high-voltage electric separator for fly ash separation. Background Technology

[0002] Fly ash is an industrial waste residue discharged from pulverized coal boilers in thermal power plants. The powder collected from the flue gas after coal combustion is called fly ash. In the process of utilizing fly ash, it is often necessary to use a high-voltage electric separator for separation.

[0003] According to the patent application CN103861739U, "This invention discloses a high-voltage electrostatic separator for fly ash separation, comprising a frame. The frame is divided into a feeding zone, a separation zone, and a receiving zone along the material separation direction. The feeding zone includes a vibrating hopper and a separator, which are installed at the top of the frame. The separator is fixed to the vibrating hopper. Two separation zones are arranged side by side below the vibrating hopper. This invention's high-voltage electrostatic separator for fly ash separation has the advantages of compact structure, low pollution, and continuous and uniform feeding."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During operation, the material is fed into the feed hopper through a material separator screen. After being heated and dried in the feed hopper, the material flows into a star feeder, which then feeds it into a vibrating hopper and a separator. The material falls smoothly onto the upper surface of the rotating cylindrical electrode through the vibrating hopper and separator. In actual use, because the feeding angle of the device is fixed, blockages are prone to occur during the feeding process, affecting the subsequent sorting effect. At the same time, fly ash is prone to fly ash during the sorting and discharge process, which affects the operating environment. Therefore, it is necessary to improve the high-voltage electrostatic separator for fly ash sorting to solve the above problems. Utility Model Content

[0028] Example 1:

[0029] In existing technologies, the fixed feeding angle of the device easily leads to blockages during the feeding process, affecting subsequent sorting results. This embodiment provides a high-voltage electrostatic separator for fly ash separation. Please refer to [link to relevant documentation]. Figure 1-5This utility model provides a technical solution: a high-voltage electric separator for fly ash separation, including a high-voltage electric separator housing 1, a support leg 2 fixedly connected to the bottom of the high-voltage electric separator housing 1, a feed hopper 3 fixedly connected to the top of the high-voltage electric separator housing 1, a heating rod 4 inside the feed hopper 3, a corona electrode 5 inside the high-voltage electric separator housing 1, a grounding drum 6 inside the high-voltage electric separator housing 1, a static electrode 7 inside the high-voltage electric separator housing 1, an adjusting feeding mechanism 8 inside the high-voltage electric separator housing 1, and a discharge dust removal mechanism 9 outside the high-voltage electric separator housing 1;

[0030] The adjusting feeding mechanism 8 includes a feeding component 81 and an adjusting component 82. The feeding component 81 is located inside the feeding hopper 3, and the adjusting component 82 is located inside the high-voltage electric separator housing 1.

[0031] Furthermore, the feeding assembly 81 includes a support base 811, which is fixedly connected to the left side of the feeding hopper 3. A first motor 812 is fixedly connected to the front of the support base 811, and a first connecting block 816 is fixedly connected to the output end of the first motor 812. A baffle 813 is fixedly connected inside the feeding hopper 3, and a feeding roller 814 is rotatably connected inside the feeding hopper 3. A limit plate 815 is fixedly connected to the left side of the feeding roller 814 to facilitate the uniform rotation of the feeding roller 814, thereby ensuring the uniform feeding of fly ash falling into the feeding hopper 3 and avoiding sorting blockage.

[0032] Furthermore, a groove is provided at the corresponding position of the limiting plate 815 and the first connecting block 816, and the first connecting block 816 is movably connected inside the groove, which makes the feeding process more stable.

[0033] Furthermore, the adjustment assembly 82 includes an electric telescopic rod 821, which is fixedly connected to the left side of the high-voltage electric separator housing 1. A second connecting block 822 is fixedly connected to the back of the electric telescopic rod 821, and a toothed plate 823 is fixedly connected to the right side of the second connecting block 822. A slide rail 824 is fixedly connected to the left side of the high-voltage electric separator housing 1, and a guide plate 825 is rotatably connected inside the high-voltage electric separator housing 1. A gear 826 is fixedly connected to the left side of the guide plate 825 to facilitate adjustment of the angle of the guide plate 825, thereby meeting the requirements for adjusting the feeding of fly ash entering the high-voltage electric separator housing 1 and increasing the subsequent separation effect.

[0034] Furthermore, the gear 826 meshes with the toothed plate 823, and the slide rail 824 has a groove at the corresponding position of the toothed plate 823, and the toothed plate 823 is slidably connected inside the groove, which facilitates a more stable adjustment process.

[0035] Example 2:

[0036] Based on Embodiment 1, in the prior art, fly ash is prone to fly ash formation during the sorting and discharge process, thus affecting the operating environment. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problems. Please refer to Embodiment 2. Figure 6 Furthermore, in conjunction with Embodiment 1, the discharge dust removal mechanism 9 includes a dust removal fan 91, which is fixedly connected to the outside of the high-voltage electric separator housing 1. A support plate 92 is fixedly connected to the outside of the high-voltage electric separator housing 1. A fixing block 93 is fixedly connected to the bottom of the support plate 92. A rotating block 94 is rotatably connected inside the fixing block 93. A dust suction plate 95 is fixedly connected to the bottom of the rotating block 94. A connecting seat 96 is fixedly connected to the right side of the support plate 92. A second motor 97 is fixedly connected to the bottom of the connecting seat 96. A rotating column 98 is fixedly connected to the output end of the second motor 97. A connecting rod 99 is rotatably connected inside the rotating block 94, which facilitates the back-and-forth swinging of the dust suction plate 95 and increases the dust suction range.

[0037] Furthermore, a suction pipe is provided between the dust removal fan 91 and the suction plate 95, and a groove is opened at the corresponding position of the rotating column 98 and the connecting rod 99, and the connecting rod 99 is rotatably connected inside the groove, which facilitates a more stable dust removal process.

[0038] In actual operation, when this device is used, the operator first feeds fly ash into the high-voltage electric separator housing 1 through the feed hopper 3. Under the action of its weight, the fly ash, along with the baffle 813, falls into the discharge roller 814. The first motor 812 rotates the first connecting block 816, which, in conjunction with the limit plate 815, causes the discharge roller 814 to rotate inside the feed hopper 3. The electric telescopic rod 821 moves the second connecting block 822, causing the toothed plate 823 to slide inside the slide rail 824. This, in conjunction with the gear 826, causes the guide plate 825 to rotate inside the high-voltage electric separator housing 1. The corona electrode 5 and the static electrode 7 work together with the brush to bring the minerals to the high-voltage electric field through the grounding drum 6. Because the corona electrode 5 continuously emits electrons, regardless of the situation... Both conductive and non-conductive fly ash acquire negative charges simultaneously. The difference lies in the different electrical properties of the conductive and non-conductive fly ash. Conductive fly ash can quickly transfer the acquired charge through the centrifugal force and gravity generated by the grounding drum 6, and drop it into the collection box along the tangent of the grounding drum 6. Non-conductive fly ash, on the other hand, cannot immediately transfer the acquired charge, thus generating a mirror-like suction force on the surface of the grounding drum 6. It is adsorbed onto the drum surface and rotates to the rear, where it is brushed off with a brush and falls to the rear. During the material collection process, since fly ash is prone to generating fly ash, the dust removal fan 91 works in conjunction with the dust suction pipe and dust suction plate 95 to remove the fly ash. The second motor 97 works to rotate the rotating column 98, which, in conjunction with the connecting rod 99, causes the rotating block 94 to rotate inside the fixed block 93, realizing the back-and-forth swinging of the dust suction plate 95.
