Description

Technical Field

[0001] The present application relates to the field of distillation kettles, and in particular to a safer distillation kettle. Background Art

[0002] A distillation kettle is a kettle used for distillation in chemical production. It heats the inside of the distillation kettle to vaporize the mixed liquid. The temperature is determined according to the vaporization points of different substances in the mixed liquid. The mixed substances are then gradually separated and liquefied. In this way, the substances in the mixed liquid can be separated with high purity and are environmentally friendly.

[0003] The utility model patent with publication number CN219355274U discloses a high-temperature distillation kettle, including a high-temperature distillation kettle body, the upper end surface of the high-temperature distillation kettle body is fixedly connected with a box cover, the upper end surface of the box cover is fixedly installed with a support column, the upper end surface of the support column is provided with a driving motor, the lower end surface of the box cover is rotatably connected with a stirring shaft through a rotating shaft, three groups of stirring rods are fixed in sequence on the outer wall surface of the stirring shaft, each group of the stirring rods has three stirring rods, and the upper and lower groups of stirring rods on the outer wall surface of the stirring shaft are provided with mounting holes at one end away from the stirring shaft.

[0004] When a still is distilling liquid, it generally needs to be heated to a higher temperature, so that the still is not only under higher pressure but also filled with hot gas. If the operator opens the end cover of the still before it has cooled completely, the hot gas will rush out of the still mouth, causing injury to the operator. Utility Model Content

[0005] In order to reduce the possibility of high temperature gas causing damage to operators when the end cover is opened, the present application provides a safer distillation kettle.

[0006] A relatively safe distillation kettle provided in this application adopts the following technical solution:

[0007] A relatively safe distillation kettle comprises a kettle body, the upper end of which is rotatably connected to an end cover, a limit gear is disposed on the outer sleeve of the end cover, a vertical safety tube is disposed within the kettle body, the upper end of the safety tube is coaxially connected to a rotating shaft, a horizontal limit rod is disposed on the outer side wall of the rotating shaft, the limit rod is provided with a rack for engaging with the limit gear at one end facing the end cover, a safety block is slidably connected in the safety tube along a vertical direction, and a rotating member is disposed at the upper end of the safety block for driving the rotating shaft to rotate when the safety block rises.

[0008] By adopting the above technical solution, when the temperature in the kettle is high, the gas in the safety tube expands due to the heat and pushes the safety block to move upward. When the safety block moves upward, the rotation shaft is driven to rotate through the transmission of the rotating part. When the rotation shaft rotates, it drives the limit rod to move toward the end cover so that the rack on the limit rod is locked with the limit gear, making it more difficult to rotate the limit gear and making it more difficult to open the end cover, thereby reducing the possibility of high-temperature gas causing damage to the operator when the end cover is opened.

[0009] Optionally, the rotating member includes a first transmission rod and a second transmission rod, the first transmission rod is coaxially arranged at the upper end of the safety block, the second transmission rod is horizontally connected to the upper end of the first transmission rod, the rotating shaft is hollow, and a threaded groove is provided on the inner side wall of the rotating shaft, and one end of the second transmission rod away from the first transmission rod is inserted into the groove.

[0010] By adopting the above technical solution, the safety block drives the first transmission rod and the second transmission rod to move up and down when moving up and down. The second transmission rod is engaged with the threaded groove when moving up and down. After the groove is subjected to force, it drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the rack to engage with the limit gear or separate from the limit gear.

[0011] Optionally, a ball is provided at one end of the second transmission rod away from the first transmission rod, and the ball is disposed in contact with the bottom of the groove.

[0012] By adopting the above technical solution, the ball plays a role in reducing the friction between the second transmission rod and the groove.

[0013] Optionally, a limiting ring is coaxially provided inside the safety tube, and the limiting ring is located directly above the safety block.

[0014] By adopting the above technical solution, the limiting ring plays a role in limiting the safety block, thereby reducing the situation where the safety block moves upward too much and moves into the rotating shaft.

[0015] Optionally, a horizontal connecting tube is provided on the side wall of the safety tube, a vertically upward indicating tube is provided at one end of the connecting tube away from the safety tube, the indicating tube extends out of the kettle body in a vertically upward direction, the indicating tube is made of transparent material, and an indicating block is slidably connected in the vertical direction inside the indicating tube.

[0016] By adopting the above technical solution, when the temperature in the kettle body rises, the air pressure in the safety tube and the connecting tube increases, thereby pushing the indicator block to move vertically upward in the indicator tube. The indicator tube is made of transparent material, which makes it convenient for the operator to observe the position of the indicator block. The temperature in the kettle body can be easily determined based on the height of the indicator block.

[0017] Optionally, a horizontal limit plate is provided at the lower end of the indicator tube, and a plurality of through holes for gas to pass through are formed on the limit plate.

[0018] By adopting the above technical solution, the limit plate plays a role in limiting the moving range of the indicator block, thereby reducing the occurrence of the indicator block moving into the safety tube.

[0019] Optionally, a blocking ring is provided at the upper end of the indicator tube.

[0020] By adopting the above technical solution, the blocking ring plays a role in limiting the moving range of the indicator block, thereby reducing the situation where the indicator block moves upward out of the indicator tube due to excessive air pressure.

[0021] Optionally, a pressure sensor is provided at the lower end of the blocking ring, the pressure sensor is electrically connected to a controller and sends the pressure value of the indicator block on the pressure sensor to the controller, the controller is electrically connected to a buzzer and controls the buzzer to make a sound when the pressure value is greater than a set value.

[0022] By adopting the above technical solution, when the temperature in the kettle is too high, the air pressure in the safety tube and the indicator tube is relatively high, the indicator block presses upward against the pressure sensor and generates a large force on the pressure sensor, and the pressure sensor sends the pressure value to the controller. When the pressure value is greater than the set value, the controller controls the buzzer to sound an alarm, reminding the operator that the temperature in the kettle is too high, thereby protecting the operator.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the temperature in the kettle is high, the rotation of the shaft drives the limit rod to move toward the end cover, so that the rack on the limit rod and the limit gear are locked, making it difficult for the limit gear to rotate and the end cover to open, thereby reducing the possibility of high-temperature gas causing damage to the operator when the end cover is opened;

[0025] 2. When the temperature in the kettle rises, the air pressure in the safety tube and the connecting tube increases, thereby pushing the indicator block to move vertically upward in the indicator tube. The indicator tube is made of transparent material, which makes it convenient for operators to observe the position of the indicator block. According to the height of the indicator block, the temperature in the kettle can be easily determined;

[0026] 3. When the temperature in the kettle is too high, the air pressure in the safety tube and the indicator tube is relatively high. The indicator block presses upward against the pressure sensor and exerts a large force on the pressure sensor. The pressure sensor sends the pressure value to the controller. When the pressure value is greater than the set value, the controller controls the buzzer to sound an alarm, reminding the operator that the temperature in the kettle is too high, thereby protecting the operator.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a relatively safe distillation kettle. Figure 1 A relatively safe distillation kettle comprises a kettle body 1, the upper end of which is threadedly connected with an end cover 11 for closing the kettle body 1, and the end cover 11 is coaxially sleeved with a limiting gear 12.

[0034] Reference Figure 1 , Figure 2 as well as Figure 3 The upper end of the kettle body 1 is rotatably connected with a vertical rotating shaft 3, and a horizontal limiting rod 4 is fixedly connected to the outer wall of the rotating shaft 3. The limiting rod 4 is fixedly connected with a rack 41 at one end facing the limiting gear 12. The rack 41 is used to engage with the limiting gear 12. When the rotating shaft 3 rotates, it drives the rack 41 to engage with the limiting gear 12. When the rack 41 engages with the limiting gear 12, the end cover 11 is difficult to rotate and difficult to open.

[0035] Reference Figure 2 as well as Figure 3A vertical safety tube 2 is fixedly connected in the kettle body 1, and the safety tube 2 is rotatably connected to the lower end of the rotating shaft 3. A safety block 21 is slidably connected in the safety tube 2 along the vertical direction. A limit ring 22 for limiting the moving range of the safety block 21 is fixedly connected in the safety tube 2. The limit ring 22 is located directly above the safety block 21. A rotating member 5 for driving the rotating shaft 3 to rotate when the safety block 21 rises is provided at the upper end of the safety block 21. The rotating member 5 includes a first transmission rod 51 and a second transmission rod 52. The rotating shaft 3 is hollow. The first transmission rod 51 is coaxially fixedly connected to the upper end of the safety block 21. The first transmission rod 51 extends into the rotating shaft 3 in the vertical upward direction, and the second transmission rod 52 is horizontally connected to the rotating shaft 3. It is flatly connected to the upper end of the first transmission rod 51, and a threaded groove 31 is provided on the inner side wall of the rotating shaft 3. A ball 521 is fixedly connected to the end of the second transmission rod 52 away from the first transmission rod 51. The ball 521 is located in the groove 31 and the end of the ball 521 away from the second transmission rod 52 is in contact with the bottom of the groove 31. The safety block 21 drives the first transmission rod 51 and the second transmission rod 52 to move up and down when moving up and down. The second transmission rod 52 passes through the ball 521 and is engaged with the threaded groove 31 when moving up and down. After the groove 31 is subjected to force, it drives the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, it drives the rack 41 to engage with the limit gear 12 or separate from the limit gear 12.

[0036] Reference Figure 1 , Figure 3 as well as Figure 4 A horizontal connecting pipe 23 is connected to the side wall of the safety tube 2. An end of the connecting pipe 23 away from the safety tube 2 is fixedly connected to a vertically upward indicating tube 6. The indicating tube 6 extends out of the kettle body 1 in a vertically upward direction. The indicating tube 6 is made of transparent plastic. A horizontal limiting plate 62 is fixedly connected to the lower end of the indicating tube 6. A plurality of through holes 621 penetrating the limiting plate 62 in a vertical direction are provided on the limiting plate 62. The through holes 621 are used for gas to pass through. A horizontal blocking ring 63 is fixedly connected to the upper end of the indicating tube 6. A vertically sliding ring 63 is provided inside the indicating tube 6. The transfer connection is provided with an indicator block 61, which is located between the blocking ring 63 and the limit plate 62 in the vertical direction. The blocking ring 63 serves to reduce the occurrence of the indicator block 61 sliding out of the indicator tube 6. When the temperature in the kettle body 1 rises, the air pressure in the safety tube 2 and the connecting tube 23 increases, thereby pushing the indicator block 61 to move in the indicator tube 6 in the vertical upward direction. The indicator tube 6 is made of transparent material, which can facilitate the operator to observe the position of the indicator block 61. The temperature in the kettle body 1 can be conveniently determined according to the height of the indicator block 61.

[0037] Reference Figure 1 as well as Figure 3A pressure sensor 64 is installed at the lower end of the blocking ring 63. The pressure sensor 64 is electrically connected to a controller 65. The controller 65 is safely connected to the kettle body 1. The controller 65 is electrically connected to a buzzer 66. The buzzer 66 is installed on the side wall of the indicator tube 6. When the temperature in the kettle body 1 is too high, the air pressure in the safety tube 2 and the indicator tube 6 is relatively large. The indicator block 61 presses upward against the pressure sensor 64 and exerts a large force on the pressure sensor 64. The pressure sensor 64 sends the pressure value to the controller 65. The controller 65 controls the buzzer 66 to sound an alarm when the pressure value is greater than the set value, reminding the operator that the temperature in the kettle body 1 is too high, thereby protecting the operator.

[0038] The implementation principle of a safer distillation kettle in the embodiment of the present application is as follows: when the temperature in the kettle body 1 is high, the air pressure in the safety tube 2 is large and pushes the safety block 21 to move upward. When the safety block 21 moves upward, it drives the first transmission rod 51 and the second transmission rod 52 to move upward. The second transmission rod 52 drives the ball 521 to move upward. When the ball 521 moves upward, it engages with the groove 31. The groove 31 is forced to drive the shaft 3 to rotate. When the shaft 3 rotates, it drives the limit rod 4 to move toward the end cover 11 so that the rack 41 on the limit rod 4 engages with the limit gear 12 on the end cover 11, making it difficult to open the end cover 11, thereby reducing the possibility of high-temperature gas causing damage to the operator when the end cover 11 is opened.

[0039] When the temperature in the kettle body 1 rises, the air pressure in the safety tube 2 and the connecting tube 23 increases, thereby pushing the indicator block 61 to move in the indicator tube 6 in the vertical upward direction. The indicator tube 6 is made of transparent material, which makes it convenient for the operator to observe the position of the indicator block 61. The temperature in the kettle body 1 can be easily determined according to the height of the indicator block 61. When the temperature in the kettle body 1 is too high, the air pressure in the safety tube 2 and the indicator tube 6 is relatively large, and the indicator block 61 presses upward against the pressure sensor 64 and exerts a large force on the pressure sensor 64. The pressure sensor 64 sends the pressure value to the controller 65. When the pressure value is greater than the set value, the controller 65 controls the buzzer 66 to sound an alarm to remind the operator that the temperature in the kettle body 1 is too high, thereby protecting the operator.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
