Description

Technical Field

[0001] This utility model relates to the technical field of suspension treatment equipment, and in particular to a shear dispersion device for nano-conductive carbon black suspension. Background Technology

[0002] Shearing reactors can be used for shear dispersion of nano-conductive carbon black suspensions. Currently, in suspension production lines, shearing reactors are generally configured with a capacity of 2000L-3000L. During stirring and shearing, the specific gravity of the bottom third of the slurry in the reactor is too high, the shearing time is too long, and the specific gravity of the slurry is uneven, which affects the production speed and results in low production efficiency.

[0003] Existing technology CN207102505U discloses a novel shearing vessel. A first motor and a second motor are respectively installed on the left and right sides of the top of the vessel. The output shaft of the first motor is connected to a first rotating shaft inserted into the shearing chamber. A turntable is connected to the bottom of the first rotating shaft. An mounting plate is installed on the top of the shearing chamber, and a shearing cover is connected to the bottom of the mounting plate via a support rod. The shearing cover is located outside the turntable. The output shaft of the second motor is connected to a second rotating shaft inserted into the conveying chamber. A spiral blade is provided on the outside of the second rotating shaft. A discharge pipe is connected to the bottom left side of the shearing chamber, and a feed inlet is provided on the top left side of the vessel. This shearing vessel, driven by the second motor, rotates the spiral blade, allowing the liquid inside the shearing chamber and the conveying chamber to circulate, resulting in better shearing and stirring of the suspension and improving the stirring efficiency of the suspension.

[0004] However, the applicant found that the above-mentioned equipment was not equipped with a filtration mechanism, which made it difficult to quickly separate solid impurities from liquid when the suspension was discharged, making it inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide a shear dispersion device for nano-conductive carbon black suspension, which aims to solve the problem that existing devices do not have a filtration mechanism, making it difficult to quickly separate solid impurities from the liquid when the suspension is discharged, resulting in inconvenience in use.

[0006] To achieve the above objectives, this utility model provides a nano-conductive carbon black suspension shearing and dispersion device, including a vessel body, a cover plate at the top of the vessel body, a discharge electric valve at the bottom, a feed pipe with a detachable threaded cap on the cover plate, and a filtration mechanism.

[0007] The filtration mechanism includes a filter box, a fixed plate, a lower filter screen, a limiting frame, an upper filter screen, a shearing device, and a stirring device. The filter box is located directly below the discharge electric valve, and a discharge valve is provided at its bottom. The fixed plate is slidably connected to the filter box and is located in the stepped cavity inside the filter box. The lower filter screen is welded to the rectangular cavity of the fixed plate. The limiting frame is slidably connected to the filter box, and its bottom abuts against the upper surface of the fixed plate. The upper filter screen is welded to the rectangular cavity of the limiting frame and is located above the lower filter screen, and its filter hole diameter is larger than that of the lower filter screen. The shearing device is located on the side of the cover plate near the vessel body. There are three stirring devices, which are arranged in a ring at 120° intervals outside the shearing device.

[0008] The shearing device includes a shearing motor and a shearing blade shaft. The shearing motor is fixed on the cover plate. The shearing blade shaft is connected to the output shaft of the shearing motor via a coupling and is located inside the reactor body.

[0009] The shearing device further includes an auxiliary cutter shaft, which is welded to the bottom of the shearing cutter shaft.

[0010] The stirring device includes a speed reducer and a stirring roller. The speed reducer is fixed on the cover plate, and there are three speed reducers, which are spaced 120° apart from each other. The stirring roller is connected to the output shaft of the speed reducer through a coupling and is located inside the reactor.

[0011] The nano-conductive carbon black suspension shear dispersion device further includes a hoisting mechanism, which includes a first hoisting column and a second hoisting column. The first hoisting column is welded to one side of the top of the cover plate; the second hoisting column is symmetrically arranged with the first hoisting column and welded to the cover plate.

[0012] This invention relates to a shearing and dispersing device for nano-conductive carbon black suspension. During processing, the suspension raw material is fed into the vessel through a feed pipe. Then, a shearing device rotates and cuts the solution to achieve shearing and dispersion. A stirring device is used for mixing. After a certain period of time, the discharge electric valve opens, and the sheared and dispersed suspension is discharged and falls into a limiting frame. Then, it undergoes tiered filtration through upper and lower filter screens to achieve solid-liquid separation. Finally, the discharge valve is opened to discharge the filtered solution. This invention solves the problem of existing equipment lacking a filtration mechanism, which makes it difficult to quickly separate solid impurities from the liquid during the discharge of the suspension, resulting in inconvenience.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Example 1:

[0021] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of a nano-conductive carbon black suspension shear dispersion device. Figure 2 This is the front view of the shearing blade axis 112. Figure 3 This is a cross-sectional view of the filter box 105. This utility model provides a shearing and dispersing device for nano-conductive carbon black suspension: it includes a vessel body 101, a cover plate 102, a discharge electric valve 103, a feed pipe 104, and a filtration mechanism. The filtration mechanism includes a filter box 105, a fixing plate 107, a lower filter screen 108, a limiting frame 109, an upper filter screen 110, a shearing device, and a stirring device. The shearing device includes a shearing motor 111, a shearing blade shaft 112, and an auxiliary blade shaft 113. The stirring device includes a reducer 114 and a stirring roller 115. This solution solves the problem that existing equipment lacks a filtration mechanism, making it difficult to quickly separate solid impurities from the liquid during suspension discharge, resulting in inconvenience. It is understood that the aforementioned solution can utilize filtration during solution discharge.

[0022] In this embodiment, the top of the vessel body 101 is provided with a cover plate 102 and the bottom is provided with a discharge electric valve 103. The cover plate 102 is provided with a feed pipe 104 with a detachable threaded cap. The cover plate 102 is fixed by bolts. The discharge electric valve 103 is used for discharging the suspension and can be automatically controlled by the control system at timed intervals. The feed pipe 104 is used for feeding the suspension raw materials.

[0023] The filter box 105 is located directly below the discharge electric valve 103, and a discharge valve 106 is provided at its bottom. The fixed plate 107 is slidably connected to the filter box 105 and is located in the stepped cavity inside the filter box 105. The lower filter screen 108 is welded to the rectangular cavity of the fixed plate 107. The limiting frame 109 is slidably connected to the filter box 105, and its bottom abuts against the upper surface of the fixed plate 107. The upper filter screen 110 is welded to the rectangular cavity of the limiting frame 109 and is located above the lower filter screen 108, and the diameter of the filter hole is larger than that of the lower filter screen 108. The shearing device is located on the side of the cover plate 102 near the vessel body 101. There are three stirring devices, which are arranged in a ring at 120° intervals outside the shearing device. The filter box 105 has a stepped cavity inside to facilitate the installation of the fixing plate 107. The outlet valve 106 is provided on one side of the bottom of the filter box 105 to facilitate the discharge of the filtered solution. The fixing plate 107 is limited by its own weight after the limiting frame 109 is installed. The lower filter screen 108 is welded and fixed in the rectangular cavity of the fixing plate 107. Manual lifting brackets are installed on both sides of the limiting frame 109 for easy removal. The four side walls of the limiting frame 109 are closed structures with a vertical through rectangular cavity. The upper filter screen 110 is welded in the rectangular cavity of the limiting frame 109. The upper filter screen 110 and the lower filter screen 108 achieve tiered filtration. The shearing device is used for the rotational shearing dispersion of the suspension, and the stirring device is used for solution stirring to accelerate the processing efficiency.

[0024] Secondly, the shearing motor 111 is fixed to the cover plate 102; the shearing blade shaft 112 is connected to the output shaft of the shearing motor 111 via a coupling and is located inside the vessel body 101. The shearing motor 111 is fixed with bolts, and the shearing blade shaft 112 is connected to its output shaft via a coupling. The bottom of the shearing blade shaft 112 has a U-shaped structure to facilitate the installation of the stirring device, and the cutting part has a rectangular blade structure.

[0025] Then, the auxiliary cutter shaft 113 is welded to the bottom of the shearing cutter shaft 112. The auxiliary cutter shaft 113 can perform rotational shearing and dispersion of the suspension in the tapered discharge area at the bottom of the vessel body 101.

[0026] Finally, three reducers 114 are fixed to the cover plate 102, spaced 120° apart from each other; the stirring roller 115 is connected to the output shaft of the reducer 114 via a coupling and is located inside the vessel body 101. The reducer 114 is fixed with bolts, and its output shaft is connected to the stirring roller 115 via a coupling.

[0027] When using this invention to address the problem of existing equipment lacking a filtration mechanism, resulting in difficulty in quickly separating solid impurities from the liquid during the discharge of the suspension solution and causing inconvenience, the process involves first feeding the suspension raw material into the vessel body 101 through the feed pipe 104. At this time, the discharge electric valve 103 is in the closed state. Then, by controlling the shear motor 111 to drive the shearing blade shaft 112 and the auxiliary blade shaft 113, the rectangular cutting sections of the shearing blade shaft 112 and the auxiliary blade shaft 113 can perform rotary cutting of the solution, achieving shearing and dispersion of the suspension. Simultaneously, the reducer 114 can drive the stirring roller 115 to stir and mix. This facilitates faster and more efficient uniform shearing and dispersion of the solution. After a certain period of time, the discharge electric valve 103 opens, and the sheared and dispersed suspension is discharged and falls into the limiting frame 109. Then, the upper filter screen 110 and the lower filter screen 108 work together to perform layered filtration to achieve solid-liquid separation. Finally, the discharge valve 106 is opened to discharge the filtered solution. Finally, the limiting frame 109 and the fixing plate 107 can be removed in sequence to quickly clean the upper filter screen 110 and the lower filter screen 108. This solves the problem that existing equipment does not have a filtration mechanism, which makes it difficult to quickly separate solid impurities from liquids when discharging the suspension, resulting in inconvenience.
