Description

Technical Field

[0001] The utility model relates to the technical field of crystallization, in particular to a novel benzotriazole crystallization device. Background Art

[0002] Benzotriazole is widely used in anti-rust oil (grease) products, mostly used in copper and copper alloy vapor phase corrosion inhibitor circulating water treatment agent, automotive antifreeze, photographic antifogging agent, polymer stabilizer, plant growth regulator, lubricant additive, UV absorber, etc.

[0003] In the process of producing benzotriazole, in order to ensure the quality of the product, it needs to be dissolved in water, and the impurities therein need to be removed by filtering with activated carbon. The solution after the impurities are removed is subjected to water-cooled crystallization to extract the product. The crystallization equipment is a water pool with a sandwich. After benzotriazole is dissolved in warm water, the impurities are filtered through activated carbon. The filtered solution is placed in the water pool, and cold water is passed through the sandwich of the water pool to cool and crystallize the solution. The disadvantage is that the cooling crystallization of benzotriazole with cold water takes a long time, has low efficiency, and wastes energy. At the same time, the solution placed in the water pool is toxic and easy to volatilize, which will cause damage to the health of the staff. Utility Model Content

[0004] The purpose of the utility model is to provide a novel benzotriazole crystallization device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A novel benzotriazole crystallization device comprises a support table, a heating box is fixedly connected above the support table, a shell is arranged inside the heating box, the shell is fixedly connected to the heating box, an air outlet, a feed port and a discharge port are respectively opened on the shell, the air outlet is connected to an air pump through a pipeline, a reinforcement plate is fixedly connected to the bottom of the support table, a motor is fixedly connected to one side of the support table, a rotating shaft is arranged below the support table, the rotating shaft is rotatably connected to the reinforcement plate, one end of the rotating shaft is fixedly connected to the output end of the motor, a crystallization component is connected to the support table, and a feeding component for continuous feeding is connected to one side of the crystallization component.

[0007] When the new benzotriazole solution needs to be crystallized, the benzotriazole solution is placed inside the shell, and then hot water not exceeding the melting point of benzotriazole is passed into the heating box through a pipe, and the hot water is used to heat the benzotriazole solution inside the shell. When the benzotriazole solution is heated, the water in the solution will gradually evaporate into water vapor and be pumped away by the air pump, so that the benzotriazole is crystallized in turn, and then the benzotriazole crystals are transported to the discharge port through the crystallization component and then collected. When the solution in the shell is reduced, the amount of solution entering the shell can be effectively controlled by the operation of the feeding component, so that the device can always precipitate benzotriazole crystals, thereby greatly improving the working efficiency of the device and reducing the harm to the staff.

[0008] A further improvement of the technical solution of the utility model is that the crystallization component includes an auger, which is rotatably connected to the heating box, the shell and the support platform respectively, and the end of the auger close to the rotating shaft is fixedly connected with a bevel gear, and the rotating shaft is fixedly connected with a bevel gear, the bevel gears are meshed with each other, and the auger is in conflict with the shell.

[0009] The above technical solution is adopted. In this solution, when the shell is heated, the motor starts, and the motor drives the rotating shaft fixedly connected to its output end to rotate, thereby transmitting power to the auger through the mutual cooperation between the bevel teeth, and then the crystals precipitated in the solution are driven to move upward to the discharge port through the rotation of the auger, thereby achieving the purpose of precipitating the crystals. Because benzotriazole solution and crystals are toxic, this can avoid direct manual contact and protect the safety of workers.

[0010] A further improvement of the technical solution of the utility model is that: the feeding component includes a box body, a support shaft is fixedly connected inside the box body, a pressure plate is arranged inside the box body, the pressure plate is slidably connected to the support shaft, a spring is fixedly connected to one side of the pressure plate, the end of the spring away from the pressure plate is fixedly connected to the box body, a feeding pipe is fixedly connected to the side of the box body away from the shell, a floating plate is arranged at the end of the pressure plate away from the spring, the floating plate is slidably connected to the support shaft, and a baffle is fixedly connected to the side of the floating plate close to the feeding pipe.

[0011] The above-mentioned technical scheme is adopted. In this scheme, when the water in the solution is evaporated, the liquid level of the solution in the shell will gradually decrease, thereby causing the height of the float plate to decrease. At this time, the solution in the feed pipe will enter. When the liquid level in the shell reaches a certain height, the float plate rises with the liquid level, thereby blocking the feed pipe. This can achieve the purpose of continuous feeding and improve the working efficiency of the device. A pressure plate and a spring are provided on the float plate to fix the position of the float plate. Because the rotation of the auger will affect the liquid level, the float plate will shake with a certain amplitude, thereby affecting the crystallization efficiency of the device.

[0012] A further improvement of the technical solution of the utility model is that the thickness of the blades of the auger close to the inner ring is lower than the thickness of the blades close to the outer ring.

[0013] By adopting the above technical solution, the thickness of the blades of the auger close to the inner circle is set to be lower, so that the solution remaining on the auger can flow down along the inner circle, thereby not affecting the precipitation of crystals.

[0014] A further improvement of the technical solution of the utility model is that a plurality of through holes are evenly arranged on the auger along the width direction of the blade.

[0015] The above technical solution is adopted, in which a plurality of through holes are provided on the auger to allow the solution to flow through the through holes, thereby preventing the solution from remaining on the auger, thereby causing the crystals to dissolve, which would greatly reduce the efficiency of crystal precipitation.

[0016] A further improvement of the technical solution of the utility model is that a plurality of protrusions are arranged on the surface of the auger.

[0017] The above technical solution is adopted, in which a plurality of protrusions are provided on the surface of the auger to increase the friction between the precipitated crystals and the surface of the auger, so that the crystals can be quickly transported to the discharge port, thereby improving the working efficiency of the device.

[0018] A further improvement of the technical solution of the utility model is that: the air outlet is located above the material outlet, a filter screen is arranged inside the air outlet, and the filter screen is fixedly connected to the air outlet.

[0019] By adopting the above technical solution, the gas outlet is arranged above the material outlet to prevent crystals from being discharged from the gas outlet. By fixing a filter screen inside the gas outlet, the crystals can be blocked outside the gas outlet, thereby improving the efficiency of crystal precipitation.

[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0021] 1. The utility model provides a novel benzotriazole crystallization device. When the novel benzotriazole solution needs to be crystallized, the benzotriazole solution is placed inside a shell, and then hot water not exceeding the melting point of benzotriazole is passed into a heating box through a pipeline, and the hot water is used to heat the benzotriazole solution inside the shell. When the benzotriazole solution is heated, the water in the solution gradually evaporates into water vapor and is pumped away by an air pump, so that the benzotriazole is crystallized in turn, and then the benzotriazole crystals are transmitted to the discharge port through a crystallization component, and then collected. When the solution in the shell is reduced, the amount of solution entering the shell can be effectively controlled by the operation of the feeding component, so that the device can always precipitate benzotriazole crystals, thereby greatly improving the working efficiency of the device and reducing the harm to the staff.

[0022] 2. The utility model provides a new type of benzotriazole crystallization device. When the shell is heated, the motor starts, and the motor drives the rotating shaft fixedly connected to its output end to rotate, thereby transmitting power to the auger through the mutual cooperation between the bevel teeth, and then the auger rotates to drive the crystals precipitated in the solution to move upward to the discharge port, thereby achieving the purpose of precipitating the crystals. Because the benzotriazole solution and crystals are toxic, direct manual contact can be avoided in this way to protect the safety of the staff.

[0023] 3. The utility model provides a new type of benzotriazole crystallization device. When the water in the solution is evaporated, the liquid level of the solution in the shell will gradually decrease, causing the height of the float plate to drop. At this time, the solution in the feed pipe will enter. When the liquid level in the shell reaches a certain height, the float plate rises with the liquid level and blocks the feed pipe. This can achieve the purpose of continuous feeding and improve the working efficiency of the device. A pressure plate and a spring are provided on the float plate to fix the position of the float plate. The rotation of the auger will affect the liquid level, causing the float plate to shake with a certain amplitude, thereby affecting the crystallization efficiency of the device.

[0034] In this embodiment, when the new benzotriazole solution needs to be crystallized, the benzotriazole solution is placed inside the shell 3, and then hot water not exceeding the melting point of benzotriazole is passed into the heating box 2 through a pipe, and the hot water is used to heat the benzotriazole solution inside the shell 3. When the benzotriazole solution is heated, the water in the solution will gradually evaporate into water vapor and be pumped away by the air pump, so that the benzotriazole is crystallized in turn, and then the benzotriazole crystals are transported to the discharge port 6 through the crystallization component, and then collected. When the solution in the shell 3 is reduced, the amount of solution entering the shell 3 can be effectively controlled by the operation of the feeding component, so that the device can always precipitate benzotriazole crystals, thereby greatly improving the working efficiency of the device and reducing the harm to the staff.

[0035] like Figure 2 As shown, in the present embodiment, preferably, the crystallization component includes an auger 10, which is rotatably connected to the heating box 2, the shell 3 and the support platform 1 respectively, and a bevel gear 11 is fixedly connected to one end of the auger 10 close to the rotating shaft 9, and a bevel gear 11 is fixedly connected to the rotating shaft 9, and the bevel gears 11 are meshed with each other, and the auger 10 is in conflict with the shell 3.

[0036] When the shell 3 is heated, the motor 8 is started, and the motor 8 drives the rotating shaft 9 fixedly connected to its output end to rotate, thereby transmitting power to the auger 10 through the mutual cooperation between the bevel teeth 11, and then the crystals precipitated in the solution are driven to move upward to the discharge port 6 through the rotation of the auger 10, thereby achieving the purpose of precipitating the crystals. Because the benzotriazole solution and crystals are toxic, this can avoid direct manual contact and protect the safety of the staff.

[0037] like Figure 3 As shown, preferably, the feeding component includes a box body 12, a support shaft 13 is fixedly connected inside the box body 12, a pressure plate 14 is arranged inside the box body 12, the pressure plate 14 is slidably connected to the support shaft 13, a spring 15 is fixedly connected to one side of the pressure plate 14, the end of the spring 15 away from the pressure plate 14 is fixedly connected to the box body 12, a feeding pipe 16 is fixedly connected to the side of the box body 12 away from the shell 3, a floating plate 17 is arranged at the end of the pressure plate 14 away from the spring 15, the floating plate 17 is slidably connected to the support shaft 13, and a baffle 18 is fixedly connected to the side of the floating plate 17 close to the feeding pipe 16.

[0038] When the water in the solution is evaporated, the liquid level of the solution in the shell 3 will gradually decrease, causing the height of the float plate 17 to drop. At this time, the solution in the feed pipe 16 will enter. When the liquid level in the shell 3 reaches a certain height, the float plate 17 rises with the liquid level, thereby blocking the feed pipe 16. This can achieve the purpose of continuous feeding and improve the working efficiency of the device. A pressure plate 14 and a spring 15 are provided on the float plate 17 to fix the position of the float plate 17. Because the rotation of the auger 10 affects the liquid level, the float plate 17 will shake with a certain amplitude, thereby affecting the crystallization efficiency of the device.

[0039] Example 2

[0040] like Figure 5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the thickness of the blades of the auger 10 close to the inner ring is lower than the thickness of the blades close to the outer ring.

[0041] In this embodiment, by setting the thickness of the blades of the auger 10 close to the inner circle to be lower, the solution remaining on the auger 10 can flow down along the inner circle, thereby not affecting the precipitation of crystals.

[0042] like Figure 5 As shown, preferably, a plurality of through holes 19 are evenly arranged on the auger 10 along the width direction of the blade.

[0043] By opening a plurality of through holes 19 on the auger 10 , the solution can flow down through the through holes 19 , thereby preventing the solution from remaining on the auger 10 , thereby causing the crystals to dissolve, which would significantly reduce the efficiency of crystal precipitation.

[0044] Example 3

[0045] like Figure 5 As shown, based on Example 2, the utility model provides a technical solution: preferably, a surface of the auger 10 is provided with a plurality of protrusions.

[0046] In this embodiment, by providing a plurality of protrusions on the surface of the auger 10, the friction between the precipitated crystals and the surface of the auger 10 can be increased, so that the crystals can be quickly transported to the discharge port 6, thereby improving the working efficiency of the device.

[0047] Example 4

[0048] like Figure 2 As shown, based on Example 3, the utility model provides a technical solution: preferably, the air outlet 4 is located above the discharge port 6, and a filter screen is provided inside the air outlet 4, and the filter screen is fixedly connected to the air outlet 4.

[0049] In this embodiment, by arranging the gas outlet 4 above the discharge port 6, crystals can be prevented from being discharged from the gas outlet 4. By fixing a filter screen inside the gas outlet 4, crystals can be blocked outside the gas outlet 4, thereby improving the efficiency of crystal precipitation.

[0050] The working principle of the novel benzotriazole crystallization device is described in detail below.

[0051] like Figure 1-5As shown, when the new benzotriazole solution (hereinafter referred to as the "solution") needs to be crystallized, the benzotriazole solution is placed inside the shell 3, and then hot water not exceeding the melting point of benzotriazole is passed through a pipe into the heating box 2, and the hot water is used to heat the benzotriazole solution inside the shell 3. When the benzotriazole solution is heated, the water in the solution will gradually evaporate into water vapor and be pumped away by the air pump, so that the benzotriazole is crystallized in turn, and then the benzotriazole crystals are transported to the discharge port 6 through the crystallization component, and then collected. When the solution in the shell 3 is reduced, the amount of solution entering the shell 3 can be effectively controlled by the operation of the feeding component, so that the device can always precipitate benzotriazole crystals, thereby greatly improving the working efficiency of the device and reducing the harm to the staff. When the shell 3 is heated, the motor 8 is started, and the motor 8 drives the rotating shaft 9 fixedly connected to its output end to rotate, so that the power is transmitted to the auger 10 through the mutual cooperation between the bevel teeth 11, and then the crystals precipitated in the solution are driven to move upward to the discharge port 6 through the rotation of the auger 10, so as to achieve the purpose of crystal precipitation. Because the benzotriazole solution and the crystals are toxic, this can avoid direct manual contact and protect the safety of the staff. When the water in the solution is evaporated, the liquid level of the solution in the shell 3 will gradually decrease, causing the height of the floating plate 17 to decrease, and the solution in the feed pipe 16 will enter. When the liquid level in the shell 3 reaches a certain height, the floating plate 17 rises with the liquid level, thereby blocking the feed pipe 16, so as to achieve the purpose of continuous feeding and improve the working efficiency of the device. A pressing plate 14 and a spring 15 are arranged on the floating plate 17 to fix the position of the floating plate 17, because the rotation of the auger 10 will affect the liquid level, causing the floating plate 17 to shake with a certain amplitude, thereby affecting the crystallization efficiency of the device. By setting the thickness of the blades near the inner circle of the auger 10 to be lower, the solution remaining on the auger 10 can flow down along the inner circle, so as not to affect the precipitation of crystals. By providing a plurality of through holes 19 on the auger 10, the solution can flow down through the through holes 19, preventing the solution from remaining on the auger 10, thereby causing the crystals to dissolve, which will greatly reduce the efficiency of crystal precipitation. By providing a plurality of protrusions on the surface of the auger 10, the friction between the precipitated crystals and the surface of the auger 10 can be increased, so that the crystals can be quickly transported to the discharge port 6, thereby improving the working efficiency of the device. By setting the gas outlet 4 above the discharge port 6, the crystals can be prevented from being discharged from the gas outlet 4. By fixing a filter screen inside the gas outlet 4, the crystals can be blocked outside the gas outlet 4, thereby improving the efficiency of crystal precipitation.

[0052] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
