Description

Technical Field

[0001] The invention relates to the technical field of monoglyceride preparation, in particular to a distillation and purification kettle device for preparing high-purity monoglyceride. Background Art

[0002] Monoglyceride, or monofatty acid glyceride, is an important type of nonionic surfactant. Monoglyceride contains a lipophilic long-chain alkyl group and two hydrophilic hydroxyl groups, and thus has good surface activity, and can be used as an emulsifier in food, cosmetics, medicine and other fields. When distilling monoglyceride, distillation equipment is required.

[0003] For example, a Chinese patent with publication number "CN116966617A" discloses "a high-purity glycerol distillation device for preparing monoglycerides", whose main structure includes a bottom plate, a distillation kettle body arranged on one side of the top surface of the bottom plate, and a rectangular box arranged on the other side of the top surface of the bottom plate, a partition is arranged in the middle of the rectangular box, the area above the partition is a placement chamber, and the area below the partition is a water storage chamber, an air outlet pipe is arranged at the top of one side of the distillation kettle body, a condenser body is arranged at one end of the air outlet pipe, the condenser body and the rectangular box are fixed by a mounting frame, a conduit is arranged at the bottom of the condenser body, a support plate is arranged above the distillation kettle body, a driving mechanism is arranged in the middle of the top surface of the support plate, and reciprocating mechanisms are arranged on both sides of the top surface of the support plate; the high-purity glycerol distillation device for preparing monoglycerides drives a stirring assembly to work through the driving mechanism, so as to stir the solution in the distillation kettle body, so as to make the solution evenly heated, thereby facilitating the increase of the distillation rate of the solution and further improving the working efficiency of the monoglyceride distillation.

[0004] In actual use, the water vapor generated during distillation enters the condenser body through the exhaust pipe, and then the water vapor is condensed into water through the action of the condenser body. The cooled water flows into the water storage chamber through the conduit to realize water collection. However, the high-temperature water vapor flows into the condenser body through its own pressure. The condensation efficiency of the high-temperature water vapor cannot be effectively mechanically controlled, which can easily cause low condensation efficiency and thus form a phenomenon of low distillation purification efficiency.

The medium injection channel 9, the No. 1 steam discharge channel 10 arranged at the top of the vertical distillation tank 1, and the No. 1 gas reflux channel 11 arranged on the circumferential surface of the vertical distillation tank 1 and connected to the high-temperature distillation cavity 3 are used in conjunction with a steam device that provides high-temperature steam. The high-temperature steam circuit of the steam device is connected to the high-temperature steam inlet channel 5 and the high-temperature steam exhaust channel 6. The monoglyceride is heated by the high-temperature steam, and the liquid monoglyceride is poured into the interior of the high-temperature distillation cavity 3 through the medium injection channel 9. After the distillation is completed, the plunger valve 8 is opened to discharge the high-purity monoglyceride located inside the high-temperature distillation cavity 3.

[0029] In order to achieve directional transport and condensation of high temperature steam, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, it is necessary to set up a steam condensation conveying mechanism 12, which is provided with a spiral impeller 1215 that can drive the high-temperature steam to flow in a directional manner when rotating and can produce a condensation effect on the high-temperature steam during the flow process, and a driving motor 123 that can drive the spiral impeller 1215 to rotate in a directional manner. When working, the refrigerant liquid inflow channel 128 and the refrigerant liquid outflow channel 129 are connected to a refrigeration circuit of a refrigerator that provides refrigerant liquid. The high-temperature water vapor will heat the inner shell of the vertical distillation tank 1. Under the influence of temperature, the monoglyceride liquid located in the high-temperature distillation cavity 3 will be heated. The high temperature causes the water in the monoglyceride liquid to evaporate, generating high-temperature steam, and the high-temperature steam flows upward into the interior of the steam conveying cavity 126. After the refrigerator is started, the refrigerant liquid will flow inside the horizontal hollow rotating shaft 1212, causing the horizontal hollow rotating shaft 1212 and the spiral impeller 1215 to produce low temperature. The rotation of the spiral impeller 1215 will cause the high-temperature steam to flow to the refrigerant liquid outflow channel 129. During the flow of the high-temperature steam, it will have a large range of contact with the horizontal hollow rotating shaft 1212 and the spiral impeller 1215. During the contact, the low-temperature horizontal hollow rotating shaft 1212 and the spiral impeller 1215 will cause the high-temperature steam to condense. The condensed water droplets and residual gas will be transported to the refrigerant liquid outflow channel 129, and then transported backward by the refrigerant liquid outflow channel 129, thereby achieving directional transportation and condensation effect of the high-temperature steam.

The horizontal hollow rotating shaft 1212 is provided with a horizontal hollow rotating shaft 1212 inside the body outflow cavity 127, and the horizontal hollow rotating shaft 1212 is installed at the separation from the horizontal hollow pipe body 121 through a mechanical sealing structure, and the interior of the horizontal hollow rotating shaft 1212 is provided with a No. 1 refrigeration liquid circulation hole 1213 with one end in an open state, and the open end of the No. 1 refrigeration liquid circulation hole 1213 is located inside the refrigeration liquid outflow cavity 127, and the horizontal hollow rotating shaft 1212 is provided with a No. 2 refrigeration liquid circulation hole 1214 connecting the steam conveying cavity 126 and the No. 1 refrigeration liquid circulation hole 1213 at the shaft body located inside the steam conveying cavity 126. A spiral impeller 1215 which is an integral structure with the horizontal hollow rotating shaft 1212 is arranged on the periphery of the shaft body located inside the steam conveying cavity 126. In order to have a temperature transfer effect under the premise of corrosion resistance, it is necessary to make the horizontal hollow rotating shaft 1212 and the spiral impeller 1215 an integral structure made of copper material. The solid end of the horizontal hollow rotating shaft 1212 is fixedly connected to the rotor 124 of the driving motor 123. It should be noted that after the driving motor 123 is started, when the rotor 124 drives the spiral impeller 1215 to rotate, the medium flow direction caused by the spiral impeller 1215 is from the No. 2 steam exhaust channel 1210 to the No. 3 steam exhaust channel 1211.

[0031] To achieve the effect of pre-storing condensed water, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 7 , it is necessary to set up a condensed liquid storage mechanism 13, which is provided with a vertical storage tank 131 for storing condensed water discharged from the spiral impeller 1215 and a No. 2 gas reflux channel 135 which is connected to the No. 1 gas reflux channel 11 and can make the gas inside the vertical storage tank 131 reflux to the high-temperature distillation cavity 3. The condensed water and gas will enter the condensed water storage cavity 132 through the No. 3 steam discharge channel 1211. Under the action of gravity, the condensed water will gather in the bottom area, and the flowing gas will reflux to the high-temperature distillation cavity 3 through the No. 2 gas reflux channel 135 to maintain the air pressure required for the circulation caused by the rotation of the spiral impeller 1215, form a balanced air pressure, and prevent the occurrence of high-temperature gas turbulence caused by the air pressure difference. When the work is completed, the liquid valve 138 can be opened to discharge the condensed water.

[0032] For the specific structure of the condensed liquid storage mechanism 13, please refer to Figure 7 , including a vertical storage tank 131 with a condensate storage cavity 132 disposed therein, a liquid reserve pipe 136 of an integrated structure disposed at the bottom end of the vertical storage tank 131, a fourth steam discharge channel 134 of an integrated structure and docking with the third steam discharge channel 1211 disposed at the top end of the vertical storage tank 131, a second gas reflux channel 135 communicating with the top area of ​​the condensate storage cavity 132 disposed on the circumferential surface of the vertical storage tank 131, the second gas reflux channel 135 docking with the first gas reflux channel 11, the ... the fourth steam discharge channel 134 of an integrated structure and docking with the third steam discharge channel 1211 disposed at the top end of the vertical storage tank 131, the second gas reflux channel 135 docking with the first gas reflux channel 11, the liquid reserve pipe 136 of an integrated structure disposed at the bottom end of the vertical storage tank 131, the fourth steam discharge channel 134 of an integrated structure and docking with the third steam discharge channel 1211 disposed at the top end of the vertical storage tank 131, the fourth steam discharge channel 134 of an integrated structure disposed at the top end of the vertical storage tank 131, the fourth steam discharge channel 134 of an integrated structure disposed The interior of the retaining tube 136 is provided with a liquid reserved cavity 133 whose top is connected to the bottom of the condensed water storage cavity 132.

In order to realize manual discharge, the liquid valve 138 needs to be a manual liquid discharge valve. The circumferential surface of the liquid retaining tube 136 is provided with a No. 1 liquid flow channel 139 which is an integral structure therewith and connected to the liquid reserved cavity 133.

[0033] To prevent damage to the equipment caused by excessive pressure due to high temperature, please refer to Figure 1 , Figure 3 and Figure 8, it is necessary to set up a pressure-type discharge mechanism 14, which is provided with a valve plate 145 inside which moves to one side after being subjected to medium pressure so that the medium can be discharged outward, and a coil spring 148 which produces an elastic damping effect on the valve plate 145. High-temperature steam will cause the internal pressure of the equipment to increase, and this pressure will produce a directional force on the valve plate 145 through the condensed water. When the force is greater than the elastic pressure of the coil spring 148, the coil spring 148 will be compressed, and the valve plate 145 will move laterally. The condensed water will flow backward through the gap between the valve plates 145, and finally will be discharged outward through the No. 3 liquid flow channel 144, thereby reducing the air pressure inside the equipment, thereby preventing the occurrence of equipment damage caused by excessive pressure formed by high temperature.

[0034] For the specific structure of the pressure type discharge mechanism 14, please refer to Figure 8 , comprising a transverse hollow shell 141, wherein a transverse liquid flow chamber 142 is arranged inside the transverse hollow shell 141, wherein a second liquid flow channel 143 which is integrally formed with the transverse liquid flow chamber 142 and communicates with one end face of the transverse liquid flow chamber 142 is arranged on one end face of the transverse hollow shell 141, wherein the second liquid flow channel 143 is butted with the first liquid flow channel 139, wherein a third liquid flow channel 144 which is integrally formed with the transverse liquid flow chamber 142 and communicates with the other end of the transverse liquid flow chamber 142 is arranged on the other end of the transverse hollow shell 141, wherein a valve plate 145 which can move axially along the transverse liquid flow chamber 142 is arranged inside the transverse liquid flow chamber 142 of the transverse hollow shell 141, wherein the valve plate 145 is provided with an inner concave structure on the end face facing the second liquid flow channel 143 The valve plate 145 has an annular embedded groove 146, and an annular closed ring 147 is embedded in the annular embedded groove 146. The circumferential surface of the valve plate 145 is provided with a plurality of concave structures and liquid flow grooves 149 for liquid flow. A coil spring 148 is placed on the other end surface of the valve plate 145. In order to generate elastic pressure, it is necessary to make the initial length of the coil spring 148 greater than the lateral length of the lateral liquid flow cavity 142. One end of the annular closed ring 147 protrudes outward relative to the end surface of the valve plate 145, and the structural radius of the inner ring of the annular closed ring 147 is greater than the structural radius of the inner hole of the No. 2 liquid flow channel 143, and the structural radius of the outer ring of the annular closed ring 147 is smaller than the distance between the liquid flow groove 149 and the center line of the valve plate 145.

[0035] The specific working principle of the present invention is to cooperate with a steam device that provides high-temperature steam, connect the high-temperature steam circuit of the steam device with the high-temperature steam inlet channel 5 and the high-temperature steam exhaust channel 6, use the high-temperature steam to heat the monoglyceride, and pour the liquid monoglyceride into the high-temperature distillation cavity 3 through the medium injection channel 9;

[0036] The high-temperature water vapor will heat the inner shell of the vertical distillation tank 1. Under the influence of the temperature, the monoglyceride liquid in the high-temperature distillation cavity 3 will be heated. The high temperature causes the water in the monoglyceride liquid to be evaporated to generate high-temperature steam. The high-temperature steam flows upward into the steam delivery cavity 126. After the refrigerator is started, the refrigeration liquid will flow inside the horizontal hollow rotating shaft 1212, causing the horizontal hollow rotating shaft 1212 and the spiral impeller 1215 to produce low temperature. The rotation of the spiral impeller 1215 will cause the high-temperature steam to flow toward the refrigeration liquid outflow channel 129. During the flow of the high-temperature steam, it will have a large range of contact with the horizontal hollow rotating shaft 1212 and the spiral impeller 1215. When in contact, the low-temperature horizontal hollow rotating shaft 1212 and the spiral impeller 1215 will cause the high-temperature steam to condense. The condensed water droplets and residual gas will be transported to the refrigeration liquid outflow channel 129, and then transported backward by the refrigeration liquid outflow channel 129, thereby achieving directional transportation and condensation effects of the high-temperature steam.

[0037] After the distillation is completed, the plunger valve 8 is opened to discharge the high-purity monoglyceride located inside the high-temperature distillation cavity 3.
