[0041] The following examples are for illustrative purposes only and are not intended to limit the scope of the present application.

[0042] EXAMPLE

[0043] REFERENCE Figures 1-4The utility model provides a stearic acid melting kettle with monitoring function, including kettle body 1, the periphery of kettle body 1 is made of heat insulating material, can reduce the loss of internal heat, thereby improve the melting speed, the inside of kettle body 1 is set up heating cavity 101, and stearic acid is placed in the inside of kettle body 1 and is located heating cavity 101, thereby fastly completes the heating melting treatment, and the upper end of kettle body 1 is equipped with heat preservation cover plate 102, and heat preservation cover plate 102 provides the closed environment for the inside of kettle body 1, thereby improve the heat storage capacity, and then improve the temperature -rising speed, and the inner wall of kettle body 1 is embedded with heat conducting block 103, and heat conducting block 103 can quickly conduct the heat of heating cavity 101 inside, so that stearic acid can melt faster, and the bottom of kettle body 1 is equipped with heat transfer mechanism 2 for heating, and heat transfer mechanism 2 quickly and uniformly transfers heat to heating cavity 101, thereby improving the overall melting speed,

[0044] The outer wall of kettle body 1 is equipped with energy supply mechanism 3 for heating and improving heating efficiency, and the energy supply mechanism 3 supplies energy for the operation of the entire device, and only one energy supply device is arranged, which is convenient for maintenance and management, and the inside of kettle body 1 is equipped with mixing mechanism 4 and impurity removal mechanism 5 for improving the melting speed, the mixing mechanism 4 cooperates with the impurity removal mechanism 5 to realize the stirring and mixing of stearic acid, so that the stearic acid can be heated more uniformly, thereby improving the melting efficiency, and the impurity removal mechanism 5 can clean the impurity particles mixed in the stearic acid particles, so that the stearic acid liquid after melting can be directly collected and used, and the side wall of kettle body 1 is equipped with temperature control mechanism 6 for regulating and controlling the internal temperature, and the temperature control mechanism 6 detects the temperature inside kettle body 1 to keep it at an effective value.

[0045] Referring to Figures 3-5 The heat transfer mechanism 2 includes a heat transfer box 201 fixed to the bottom of the kettle body 1 and located directly below the heating cavity 101, and the heat transfer box 201 can also directly transfer the internal heat to the heating cavity 101, a plurality of heat transfer pipes 203 are installed through the inner wall of the heat transfer box 201, the heat transfer pipes 203 are used to receive external heat, so as to input the external heat into the heat transfer box 201, a plurality of circulating pipes 205 are installed on the upper end of the heat transfer box 201, the circulating pipes 205 are connected to the bottom of the heating cavity 101, and the heat transfer is completed by using the circulating pipes 205 to exchange the medium.

[0046] The inner wall of the heat transfer box 201 is provided with a pair of electric connection plates 204, and the two electric connection plates 204 are provided with electric connection sheets 208, and the two electric connection sheets 208 are fixedly connected with a floating plate 207, and the floating plate 207 is provided with copper wires to electrically connect the two electric connection sheets 208, thereby realizing the electrical conduction of the two electric connection plates 204. The two sides of the heat transfer box 201 are provided with gas collecting sleeves 202, and the heat transfer pipes 203 connect the two gas collecting sleeves 202. One of the gas collecting sleeves 202 is connected with the energy supply mechanism 3, and the energy supply mechanism 3 supplies heat to the gas collecting sleeve 202, and then the heat is dispersed through the plurality of heat transfer pipes 203, so that the heat is more quickly and uniformly dispersed in the heat transfer box 201, realizing the rapid heating of the heat transfer box 201, thereby improving the heat transfer efficiency. The side wall of the other gas collecting sleeve 202 is provided with an exhaust pipe 206, which leads out the heat transfer medium remaining after heat transfer, avoids heat accumulation, and facilitates subsequent heat utilization;

[0047] The heat transfer box 201 is filled with carbon tetrachloride, and the boiling point of carbon tetrachloride is higher than that of stearic acid, and the density is greater than that of water. The inside of the heating cavity 101 is filled with a mixture of water and carbon tetrachloride. Since carbon tetrachloride and water are not mutually soluble, they will be stratified, and carbon tetrachloride will be located in the lower region due to its high density. The inside of the circulating pipe 205 is provided with a one-way valve and an electromagnetic valve. The circulating pipe 205 is divided into two types, and the two types are the same in number and are arranged at intervals, but the internal one-way valves are opposite in direction.

[0048] When the temperature in the heat transfer box 201 rises, the carbon tetrachloride inside it will be heated to vaporization, thereby reducing the amount of liquid, causing the floating plate 207 to move downward with the liquid surface, thereby causing the electric connection sheet 208 to contact the electric connection plate 204, causing the two electric connection plates 204 to be conductive. The electromagnetic valve in the circulating pipe 205 is opened, and the carbon tetrachloride vaporized at the bottom rapidly diffuses upward in the form of bubbles, and the carbon tetrachloride in the heating cavity 101 moves downward through the corresponding circulating pipe 205, realizing exchange. After the liquid surface recovers, heating continues, and the carbon tetrachloride rising in the form of bubbles will diffuse into the upper water flow, causing the temperature of the water flow to rise, and the bubbles diffuse, the overall heat conduction is more uniform and fast, the melting of stearic acid is more uniform and efficient, and the water temperature is lower. After the rising carbon tetrachloride is heat transferred, it is condensed to lower the temperature, thereby sinking after recovering to the liquid state, thereby facilitating subsequent circulation and diffusion heat exchange;

[0049] After continuous heating, the water temperature will be much higher than the required holding temperature of stearic acid, since the boiling point of carbon tetrachloride is only slightly higher than that of stearic acid, so when the water temperature reaches the boiling point of carbon tetrachloride, it is not necessary to increase the temperature any more, and the temperature can be maintained. When the water temperature reaches the boiling point of carbon tetrachloride, the vaporized carbon tetrachloride will not be liquefied by a large amount of heat transfer in the upward process, but will pass through the water layer in the form of bubbles, and then reach the top of the heating cavity 101, and then trigger the temperature control mechanism 6, and stop heating the heat transfer box 201, thereby controlling the temperature, so that the energy can be used for other parts;

[0050] With reference to Figure 4 and Figure 8 , the temperature control mechanism 6 comprises a water replacement tank 601 mounted on the outer wall of the kettle body 1, and a cooling groove 602 is formed in the side wall of the kettle body 1, and a condensing plate 603 is mounted at the bottom of the cooling groove 602, and the condensing plate 603 is located at the inner top of the heating cavity 101, and a water pump is mounted in the water replacement tank 601 for pumping water, and a water return pipe 604 and a water inlet pipe 605 are mounted on the side wall of the cooling groove 602 and are connected with the inside of the water replacement tank 601, and under the drive of the water pump, the circulation of cooling water is realized by the water return pipe 604 and the water inlet pipe 605, so as to control the temperature of the condensing plate 603;

[0051] A pair of electrical connecting columns 606 are fixed to the inner wall of the upper part of the heating cavity 101, and after the carbon tetrachloride is vaporized and overflowed, the water level in the heating cavity 101 will be lowered, so that the electrical connecting columns 606 are not connected by water, thereby transmitting a signal for stopping the heating of the heat transfer box 201 by the energy supply mechanism 3, and at the same time, the water pump in the water replacement tank 601 is operated to realize the cooling of the condensing plate 603, so that the carbon tetrachloride vaporized in the upper part is effectively liquefied and then drips after accumulation, thereby restoring the heating of the heating cavity 101, so that the temperature in the heating cavity 101 is always maintained at an effective value, and will not be overheated due to continuous heating, nor will it be continuously cooled due to stopping heating, thereby achieving the purpose of monitoring the holding temperature;

[0052] With reference to Figures 6-7 , the energy supply mechanism 3 comprises a vortex box 301 mounted on the outer wall of the kettle body 1, and a vortex pipe is arranged in the vortex box 301, and the vortex pipe outputs cold and hot air streams after working, which can be used for heating and driving, and a hot air pipe 302 and a cold air pipe 303 are mounted on the side wall of the vortex box 310 and output high and low temperature air streams respectively, and the hot air pipe 302 is connected with the gas collecting sleeve 202 for supplying heat to the heat transfer mechanism 2, and the side wall of the hot air pipe 302 is connected with a branch pipe 304, and a valve is arranged in the hot air pipe 302, and when the heat transfer mechanism 2 does not need to be heated, the supply of hot air to the heat transfer mechanism 2 is stopped, and the branch pipe 304 is filled instead, so that the kinetic energy of the air stream is fully utilized;

[0053] With reference to Figures 9-11The mixing mechanism 4 comprises a mixing spindle 401 which is sealingly and rotatably connected with the inner wall of the kettle body 1. The outer wall of the kettle body 1 is fixed with an exhaust cover 402 and a gas collecting cover 403. The two ends of the mixing spindle 401 are located in the exhaust cover 402 and the gas collecting cover 403 respectively. The two ends of the mixing spindle 401 are fixed with driving blades 404. The two groups of driving blades 404 are located in the exhaust cover 402 and the gas collecting cover 403 respectively. The impurity removal mechanism 5 is provided with multiple groups and is installed on the side wall of the mixing spindle 401.

[0054] The side wall of the exhaust cover 402 is provided with an exhaust hole 405. The two ends of the mixing spindle 401 are provided with an air inlet hole 406 and an exhaust hole 407 respectively. The air inlet hole 406 and the exhaust hole 407 are connected with the gas collecting cover 403 and the exhaust cover 402 respectively. The exhaust pipe 206 is connected with the gas collecting cover 403. The cold flow pipe 303 and the branch pipe 304 are connected with the exhaust cover 402. The cold gas flow is filled into the exhaust cover 402 through the cold flow pipe 303, which will impact the driving blades 404, thereby driving the mixing spindle 401 to rotate. The airflow in the exhaust pipe 206 will be filled into the gas collecting cover 403, which will also drive the driving blades 404 to rotate, thereby making the mixing spindle 401 rotate. The rotation of the mixing spindle 401 will drive the impurity removal mechanism 5 to rotate, thereby stirring the stearic acid and making the stearic acid be stirred to be heated more uniformly.

[0055] With reference to Figures 11-14 The impurity removal mechanism 5 comprises an installation rod 501 which is fixed on the circumferential side wall of the mixing spindle 401. The bottom of the installation rod 501 is fixed with a preheating box 502. The bottom of the preheating box 502 is sealingly and rotatably connected with a rotating block 506. The bottom of the rotating block 506 is fixed with an intercepting frame 507 which can rotate under the driving. The inner wall of the intercepting frame 507 is installed with multiple groups of intercepting columns 508.

[0056] The top of the installation rod 501 is installed with an air inlet pipe 503 and an air outlet pipe 504. One end of the air inlet pipe 503 and the air outlet pipe 504 is connected with the preheating box 502. The other end of the air inlet pipe 503 and the air outlet pipe 504 is connected with the air inlet hole 406 and the exhaust hole 407 respectively. The hot gas filled into the gas collecting cover 403 by the exhaust pipe 206 will finally enter the air inlet hole 406, then enter the preheating box 502 through the air inlet pipe 503, be heated in the preheating box 502, be introduced into the exhaust hole 407 through the air outlet pipe 504, then enter the exhaust cover 402 and finally be discharged.

[0057] The inner wall of the preheating box 502 is provided with a plurality of heat transfer columns 509, which are in contact with the intercepting columns 508 one by one. When the airflow heats the preheating box 502, the temperature of the heat transfer columns 509 will be greatly increased. The heat transfer columns 509 are made of excellent heat-conducting materials, so they can effectively transfer heat to the intercepting columns 508, thereby increasing the surface temperature of the intercepting columns 508 and the preheating box 502, so as to achieve hot stirring, so that the accumulated stearic acid particles can be effectively stirred and melted, improving the melting efficiency.

[0058] The end of the rotating block 506 is fixed with a torsion bar 505, and the other end of the torsion bar 505 is fixed with the inner wall of the preheating box 502. The torsion bar 505 is made of a torsionally arranged memory metal strip. When the torsion bar 505 reaches the transformation temperature, it will return to a straight strip state from a torsional state, thereby generating torsion, and further driving the rotating block 506 to rotate, so that the intercepting frame 507 rotates by ninety degrees. The gap between the intercepting columns 508 is small, and impurities are stuck in the gap during rotation and cannot be separated, so that the intercepting columns 508 can carry out the impurities mixed in the melted stearic acid.

[0059] The side wall of the intercepting frame 507 is fixed with a collecting box 510, and the inner wall of the collecting box 510 is connected with a stop block 511 through mounting bolts 512. The inner wall of the collecting box 510 is fixed with a guide block 513, and the side wall of the guide block 513 is fixed with a limiting plate 514. The side wall of the stop block 511 abuts against a gravity block 515. The gravity block 515 abuts against the stop block 511 by relying on its own weight, so as to realize the closure of the port of the collecting box 510. The side wall of the gravity block 515 is fixed with a collecting sleeve 516, and the end of the collecting sleeve 516 is provided with a slot 517. The limiting plate 514 is slidingly connected with the inner wall of the slot 517. The limiting plate 514 cooperates with the slot 517, so that the movement of the collecting sleeve 516 and the gravity block 515 is more stable. The side walls of the gravity block 515 and the guide block 513 are both inclined surfaces with guiding effect.

[0060] After the impurities are carried out by the intercepting columns 508, the impurities are rotated to the upper region along with the intercepting columns 508. Under the action of gravity, the impurities will roll down along the intercepting columns 508. At the same time, under the action of gravity, the gravity block 515 will slide into the collecting box 510, so that a gap is formed between the gravity block 515 and the stop block 511, so that the rolling impurities can pass through the gap and enter the inside of the collecting box 510 under the guidance of the gravity block 515, thereby completing the collection.

[0061] In the process of the collection box 510 rotating back to the lower position, the impurities enter the collection sleeve 516 due to the guidance of the guide block 513, so that the impurities do not fall from the gap when the collection box 510 reaches the lower position completely, and thus the cleaning of the impurities can be continued. When artificial treatment is needed, the blocking block 511 can be removed by dismounting the mounting bolt 512, and then the collection sleeve 516 can be taken out, so that the impurities can be conveniently treated.

[0062] The above description is only the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
