Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing equipment for dispersants, and specifically relates to an apparatus suitable for preparing a dispersant containing trithiocarbonate. Background Art

[0002] The raw materials of dispersants generally include surfactants, polymers, colloids, etc. By selecting different surfactants as the main functional components of the dispersants, different dispersion effects can be achieved, and at the same time, the dispersants themselves exhibit different physical and chemical properties. The main functional component of the dispersant containing a trithiocarbonate structure (trithiocarbonate-based dispersant) is trithiocarbonate (thiocarbamate ester). Trithiocarbonate-based dispersants have advantages such as good surface activity, complexing ability, dispersibility, stability, and reactivity.

[0003] While showing good dispersion performance, compared with non-viscous dispersants, trithiocarbonate-based dispersants have a certain viscosity, although their actual viscosity varies slightly with temperature and concentration. Therefore, in the process of mixing with auxiliary materials such as polymers and colloids, it is necessary to consider how to remove the mixture (dispersant) remaining on the inner wall of the reaction kettle.

[0004] For example, the cleaning component disclosed in the utility model patent with the publication number CN219596501U and the name "An apparatus for preparing a dispersant" is arranged on the side of the stirring blade and can scrape and clean the dispersant on the inner wall during the stirring process. Summary of the Utility Model

[0005] The inventor found that when the cleaning component of the prior art is applied to the preparation equipment for trithiocarbonate-based dispersants, after a period of use, the cleaning component itself will adhere to and accumulate the mixture (dispersant), which affects the cleaning effect of the cleaning component. Therefore, in this application, the cleaning mechanism and the stirring mechanism are detachably assembled to facilitate the separate cleaning of the cleaning mechanism and avoid the cleaning mechanism itself adhering to the mixture and affecting its cleaning effect. Specifically, the following technical solutions are adopted:

[0022] In order to enable those skilled in the art to better understand the technical solutions in the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] Embodiment: Refer to Figures 1 to 4The preparation equipment for the trithiocarbonate dispersant shown includes a reaction kettle 1, a stirring mechanism 2, a cleaning mechanism 3, and a PLC control cabinet. Among them, the reaction kettle 1 is any feasible product in the prior art. For example, it includes a kettle body, an upper end cover 11, a liquid outlet at the bottom, and a liquid outlet pipe connected to the liquid outlet. A switch valve is fixedly connected to the liquid outlet pipe. Opening or closing the switch valve can control the outflow of the dispersant from the liquid outlet pipe 3.

[0024] The stirring mechanism 2 includes a power source 21, a rotating shaft 22 arranged along the axial direction of the reaction kettle 1, and stirring paddles 23 arranged along the radial direction of the reaction kettle 1. The power source 21 is a motor, which is screwed and installed on the upper end cover 11 through a motor bracket. An installation hole is opened on the upper end cover 11. The output shaft of the power source 21 is installed with a rotating shaft 22 through a coupling. The rotating shaft 22 passes through the installation hole through a bearing and extends into the reaction kettle 1, and the other end is installed at the bottom of the reaction kettle 1 through a bearing.

[0025] The stirring paddle 23 includes an installation shaft 231 arranged along the radial direction of the reaction kettle 1, and paddle blades 232 screwed and installed on the installation shaft 231. One end of the installation shaft 231 is screwed and installed on the rotating shaft 22, and the other end has a first assembly structure 24. The first assembly structure 24 includes a first blind hole 241 opened along the axial direction of the installation shaft 231, and a pair of through holes 242 opened along the radial direction of the installation shaft 231. The pair of through holes 242 are symmetrically arranged and communicated with the first blind hole 241.

[0026] In this embodiment, a pair of installation shafts 231 are symmetrically arranged at the same height of the rotating shaft 22, and two paddle blades 232 are symmetrically arranged on each installation shaft 231; in the axial direction of the rotating shaft 22, multiple pairs of installation shafts 231 as described above are arranged, for example, two pairs.

[0027] The cleaning mechanism 3 includes a scraping strip 31 in contact with the inner wall of the reaction kettle 1, a second assembly structure 32 fixedly arranged on the scraping strip 31, and a plug-in member 33.

[0028] The scraping strip 31 is a strip-shaped member with rigidity, for example, a stainless steel strip. The length of the scraping strip 31 is basically the same as the height of the reaction kettle 1, or slightly shorter. The cross-sectional shape of the scraping strip 31 can be that of the prior art, for example, including scrapers on both sides. In this embodiment, the scraping surface of the scraping strip 31 relatively has an installation surface. The second assembly structure 32 is welded or screwed on the installation surface.

[0029] The quantity and position of the second assembly structure 32 correspond to those of the first assembly structure 24 respectively, so as to facilitate the connection between the two. The second assembly structure 32 includes an installation pin 321 coaxially arranged with the installation shaft 231, and a second blind hole 322 opened along the axial direction of the installation pin 321.

[0030] Meanwhile, in this embodiment, a plug-in member 33 is provided. One end of the plug-in member 33 is connected to the first assembly structure 24, and the other end is detachably connected to the second assembly structure 32. The scraping strip 31 is installed through multiple groups of second assembly structures 32 and plug-in members 33 that cooperate with the first assembly structure 24.

[0031] Specifically, the plug-in member 33 includes a pair of movable pieces 331 symmetrically arranged. One end of the movable piece 331 is provided with a pressing block 332 by welding. The pair of movable pieces 331 are connected by a compression spring 333. The pressing block 332 is a cylindrical protrusion. The compression spring 333 includes a pair, and the installation positions of the pair of compression springs 333 are respectively located in the first blind hole 241 and the second blind hole 322. One end of the pair of movable pieces 331 is inserted into the first blind hole 241, and the pressing block 332 extends out of the first blind hole 241 from the through hole 242. The other end of the movable piece 331 is inserted into the second blind hole 322.

[0032] Preferably, a pair of limiting grooves 323 are formed on the inner wall of the second blind hole 322. The pair of limiting grooves 323 are symmetrically arranged. A limiting block 334 is fixedly provided at the other end of the movable piece 331, and the limiting block 334 is clamped in the limiting groove 323. In order to enable the pair of movable pieces 331 with the limiting blocks 334 to smoothly enter the second blind hole 322, those skilled in the art know that an inclined surface should be provided on the end face of the limiting block 334.

[0033] Further preferably, at least two jacks 243 are formed on the end face of the mounting shaft 231, and a pin 324 that is inserted and matched with the jack 243 is provided on the end face of the pin 321.

[0034] In some embodiments, multiple mounting shafts 231 are aligned in the axial direction of the reaction kettle 1, so that the scraping strip 31 can be vertically arranged. In some other embodiments, adjacent mounting shafts 231 can be staggered in the same direction, so that the scraping strip 31 can be inclined. When the scraping strip 31 is inclined, the scraping strip 31 should have a curvature adapted to the inner wall of the reaction kettle 1 to ensure that the scraping surface of the scraping strip 31 always abuts against the inner wall. The inclined scraping strip 31 has lower fluid resistance and lower interference with the stirring process of the dispersant.

[0035] In this embodiment, there is a detachable assembly relationship between the cleaning mechanism 3 and the stirring mechanism 2 of the preparation equipment for the trithiocarbonate dispersant, so as to facilitate the separate cleaning of the cleaning mechanism 3, avoid the cleaning mechanism 3 itself from adhering to the mixture and affecting its cleaning effect, and enable it to have high cleaning efficiency and service life.

[0036] Specifically, after the preparation of the trithiocarbonate dispersant is completed, use a gantry crane or other equipment with equivalent functions to open the upper end cover 11, and the stirring mechanism 2 and the cleaning mechanism 3 are taken out together with the upper end cover 11. Then, use tools to simultaneously squeeze a pair of pressing blocks 332 to move a pair of movable pieces 331 closer together as a whole, so that the limiting block 334 is disengaged from the clamping relationship with the limiting groove 323, so that the plug-in member 33 can be taken out from the second blind hole 322 to separate the scraping strip 31 and the mounting shaft 231. After the scraping strip 31 is removed, it can be cleaned separately.

[0037] Those skilled in the art know that the plug-in member 33 should have a short distance. For example, the length of the plug-in member 33 is 2 cm - 3 cm, so that the downward pressure of the pressing block 332 can drive a pair of movable pieces 331 closer together as a whole, and at the same time, the stability of the connection can be ensured.

[0038] In a preferred embodiment, a support frame 12 is provided at the bottom of the reaction kettle, the upper end of the rotating shaft 22 is rotatably connected through the upper end cover 11 of the reaction kettle 1, and the lower end is rotatably connected to the support frame 12 through a rotating bearing.

By reading the above description, many embodiments and many applications other than the provided examples will be obvious to those skilled in the art. Therefore, the scope of this teaching should not be determined with reference to the above description, but should be determined with reference to the appended claims and the full scope of the equivalents of these claims.
