As is well known, ethanolamine sulfates are viscous liquids without an absolute setting temperature, which solidify into a solid state at ambient temperature, and the finished product is delivered to the customer typically in standard blocks.
In the prior art, viscous high-temperature liquid ethanolamine sulfuric acid ester is sprayed and cooled through a stainless steel conveying belt from the reaction tail end, and the method has the disadvantages of large investment and large occupied space of the stainless steel conveying belt and inconvenience for cutting into small blocks.
The technical method provided by the invention ingeniously solves the technical problems.
The ethanolamine sulfuric acid ester efficient cooling and cutting machine shown in figures 1-4 is used for rapidly cooling and cutting liquid ethanolamine sulfuric acid ester, and comprises a horizontally arranged receiving hopper 1 and two cooling rollers 2 which are horizontally arranged above the receiving hopper 1 and are arranged in parallel, wherein the cooling rollers 2 can rotate around the central line thereof, the middle parts of the cooling rollers 2 penetrate through at least one spray pipe 3 which can spray towards the inner wall of a pipe body in a direction of 360 degrees without dead angles, the two cooling rollers 2 are spaced at a certain interval, a dressing hopper 4 which coats the surfaces of the two cooling rollers 2 with ethanolamine sulfuric acid ester in a high-temperature viscous state is arranged between the two cooling rollers 2, the coating mode is that the partial outer wall of the cooling roller 2 is immersed at the side edge of the dressing hopper 4 (namely the dressing hopper 4 is filled with ethanolamine sulfuric acid ester, and the ethanolamine sulfuric acid ester is allowed to partially infiltrate into the outer wall of the cooling rollers, thus, due to the action of the spraying water, the ethanolamine sulfuric acid ester with high temperature and viscosity is continuously coated on the wall of the rotating cooling roller 2 and is cooled and solidified. In addition, the cooling machine is also provided with a cutting knife 5 for cutting hardened finished ethanolamine sulfuric acid ester, the front surface of the cutting knife 5 looks like a large stainless steel comb with the same tooth width and the same space between the teeth of the comb, but the side surface of the whole comb is in a circular arc shape and is tightly attached to the cylinder wall of the cooling roller 2, so that the cooled and solidified ethanolamine sulfuric acid ester is continuously broken by the staggered arrangement, and the tooth surface of the cutting knife 5 is divided into strips with the same width and the same length; the dressing hopper 4 comprises a hopper body 4a, a hopper side wall 4b which is in contact with the wall of the cooling roller and a scraper 4c which is erected above the hopper body and can adjust the distance between the scraper and the cooling roller, and a tension spring 4d is arranged between the side walls of the dressing hopper 4 close to the wall of the cooling roller 2.
The scraper 5 in this patent mainly realizes that the cooling roller 2 cylinder wall that partly soaks in dressing hopper 4 carries out even blade coating, because the ethanolamine sulfuric acid fat that the reaction produced is viscous liquid state, and liquid ethanolamine sulfuric acid fat passive coating is on cooling roller 2 cylinder wall, obviously this kind of mode can not artificial control the thickness of the ethanolamine sulfuric acid fat of coating on cooling roller 2 wall, consequently in order to ensure to obtain the ethanolamine sulfuric acid fat of even thickness, need adopt the scraper that has certain interval with cooling roller wall face, scrape unnecessary ethanolamine sulfuric acid fat.
Furthermore, since passive coating is adopted, the coating effect can be ensured only by keeping the outer surface of the cooling roller dry, and therefore, a cleaning roller 5a driven by a motor is arranged inside the scraper;
two ends of the cooling roller 2 are provided with circumferential gears 14 which are meshed with each other, and the two cooling rollers are meshed with each other and jointly driven by a driving motor 13 to rotate oppositely;
in the actual design, the length of the cooling roller 2 is longer than the width of the receiving hopper 1, otherwise, spray-cooled cooling water flows into the receiving hopper, and therefore, spray water recovery tanks 9 are also arranged at the two ends of the barrel of the cooling roller; the hot water recovered from the water tank is returned to the cooler 11 through the pipe 10, and the cooler 11 sends the cooled water to the shower pipe 3 through the shower header pipe 12.
In order to obtain better cooling effect, this application still provides a purpose-made cooling drum, it is through being double-deck jacket design with the cooling drum setting, form the runner 2a that holds the cooling water in cylinder inner wall space, its runner 2a is the screw thread form, from the one end flow direction other end of cooling drum, fin 2a1 that increases the heat transfer has still been set up in the runner 2a, so, both ends at cooling drum 2 set up shower 3, shower 3 sprays the cooling water respectively in the different runners 2a of cylinder both sides, just can realize the heat transfer of better effect, compare in stainless steel cooling device, the radiating effect is showing.
In general, the shower can be designed as follows: the device comprises a pipe body 3a and a nozzle 3b arranged on the pipe body 3a, wherein one end of the pipe body is closed, and the other end of the pipe body is connected with a high-pressure water pipe through a quick connector; however, in view of achieving cooling as uniformly as possible, it is necessary to provide a special arrangement of the nozzles, for example, to design the nozzle openings of the nozzles to be flattened, and to make the cooling liquid mist surfaces sprayed from different nozzles to intersect with each other, so that the cooling position does not have any dead space.
In consideration of the dressing process, the cooling roller 2 continuously takes away the heat in the ethanolamine sulfuric acid ester dressing hopper 4, so that the ethanolamine sulfuric acid ester feed liquid is possibly solidified directly in the dressing hopper, the cooling roller 2 is locked, and therefore the heater 4e is further arranged in the dressing hopper.
The same, in order to avoid appearing the local coagulation caking in the dressing hopper, still be equipped with the agitating unit 4f that prevents the feed liquid local cooling caking, this agitating unit 4f cooperates together with heating device 4e, realizes heating and the even stirring to the feed liquid, agitating unit includes two sets of horizontal installation churns 4f in the dressing hopper, be equipped with a plurality of stirring vane of evenly arranging on the outer wall of churn 4 f.
In addition, the cooling roller 2 can be driven by a belt or a gear, and in general, the external driving motor is used for driving the cooling roller to rotate in a predetermined direction, so that the ethanolamine sulfate in the dressing hopper is continuously coated on the surface of the cooling roller.
The above embodiments are preferred implementations of the present invention, and the present invention can be implemented in other ways without departing from the spirit of the present invention.
Some of the drawings and descriptions of the present invention have been simplified to facilitate the understanding of the improvements over the prior art by those skilled in the art, and some other elements have been omitted from this document for the sake of clarity, and it should be appreciated by those skilled in the art that such omitted elements may also constitute the subject matter of the present invention.
