Technical Field
[0001] This application relates to the field of chemical technology, and in particular to a device for heavy component of bromonitroethanol distillation residue. Background Technology
[0002] Brominnitrophenol is a white to pale yellow or yellowish-brown crystalline powder at room temperature. It is odorless and tasteless, readily soluble in water, ethanol, and propylene glycol, but sparingly soluble in chloroform, acetone, and benzene. Brominnitrophenol is mainly used as a preservative and bactericide. It is added to cosmetics such as shampoos, balms, and creams at concentrations of 0.01%-0.02%. It can also be used in detergents and fabric treatments. As a bactericide, it effectively controls various plant pathogenic bacteria. Treatment of cotton seeds with brominnitrophenol can prevent cotton black arm disease and bacterial wilt caused by cotton angular leaf spot fungus, without causing phytotoxicity to cotton. It can also be used for rice bakanae disease. Furthermore, it is used in industrial circulating water systems, paper pulp, coatings, plastics, cosmetics, wood, cooling water circulation systems, and for industrial applications such as sterilization, mildew prevention, preservation, and algae control. Distillation is an essential step in the production of bromonitol. However, the bromonitol distillation residue produced during distillation can cause significant environmental damage. Therefore, bromonitol distillation residue heavy component processing equipment is frequently used to treat the distillation residue. This equipment can effectively separate and recover the heavy components in the bromonitol distillation residue, thereby improving the resource recovery rate.
[0003] In existing technologies, the method for treating heavy component components of bromonitroethanol distillation residue is to redistill the residue and separate substances with different boiling points by controlling conditions such as temperature and pressure. However, in actual use, the heavy component components device for bromonitroethanol distillation residue still has at least the following shortcomings: it does not have the function of crushing bromonitroethanol distillation residue, and it does not have the function of turning and stirring the residue during the distillation process. Directly heating the large-particle-size bromonitroethanol distillation residue causes the residue to accumulate, which reduces the heating efficiency and uniformity of the residue during the distillation process, resulting in a decrease in the efficiency of separating and recovering heavy components from the bromonitroethanol distillation residue.
[0004] Therefore, we propose a device for heavy component of bromonitroethanol distillation residue to solve the above problems. Utility Model Content

[0024] See Figure 1 , Figure 2 and Figure 3This application provides a device for heavy components in bromonitroethanol distillation residue, including a bromonitroethanol distillation residue treatment box 1. The bromonitroethanol distillation residue treatment box 1 has a crushing chamber 2 and a distillation chamber 3. The crushing chamber 2 provides space for crushing the bromonitroethanol distillation residue, and the distillation chamber 3 provides space for distilling the bromonitroethanol distillation residue. This device can separate and recover heavy components from the bromonitroethanol distillation residue. The crushing chamber 2 is located above the distillation chamber 3.

A feeding hole is provided at the top of the crushing chamber 2, and a sealing plug 4 is threaded into the feeding hole to seal it. A discharge hole 5, connected to the distillation chamber 3, is provided on the bottom inner wall of the crushing chamber 2 to allow the crushed bromonitroethanol distillation residue to enter the distillation chamber 3 through the discharge hole 5. A filter screen 12 is fixedly installed inside the distillation chamber 3. The filter screen 12 is used to block the crushed bromonitroethanol distillation residue, ensuring that the residue remains on the upper surface of the screen. The screen 12 has a concave arc shape. An electric heating tube 13 is fixedly installed on the rear inner wall of the distillation chamber 3, located above the screen 12, to heat the interior of the distillation chamber 3. It should be noted that the electric heating tube 13 is a temperature-adjustable type, allowing the interior of the distillation chamber 3 to be heated to a suitable temperature as needed. A booster pump 14 is fixedly installed on the left outer wall of the bromonitroethanol distillation residue treatment box 1. An exhaust pipe 15 is fixedly installed at the discharge end of the booster pump 14, with one end extending into the distillation chamber 3 and located above the screen 12. This allows the boosted air generated by the booster pump 14 to be delivered into the distillation chamber 3, achieving a boosting effect. A one-way valve is fixedly installed on the exhaust pipe 15 to control the unidirectional flow of the boosted air.
[0025] The bromine nitrol distillation residue treatment tank 1 is equipped with a crushing mechanism, a sealing mechanism, and a turning mechanism from top to bottom. The crushing mechanism is used to crush the bromine nitrol distillation residue, the sealing mechanism is used to block the discharge hole 5, and the turning mechanism is used to stir the bromine nitrol distillation residue.
[0026] In this embodiment, a distillation gas discharge pipe 16 and a distillate discharge pipe 18 are fixedly installed on the right outer wall of the bromonitroethanol distillation residue treatment tank 1. The distillation gas discharge pipe 16 is connected to the pulverizing chamber 2, and the distillate discharge pipe 18 is connected to the distillation chamber 3. A first solenoid valve 17 is fixedly installed on the distillation gas discharge pipe 16, and a second solenoid valve 19 is fixedly installed on the distillate discharge pipe 18. The distillation gas discharge pipe 16 is used to discharge the gas generated during the distillation of the bromonitroethanol distillation residue, and the distillate discharge pipe 18 is used to discharge the distilled fluid substance. It should be noted that one end of the distillation gas discharge pipe 16 is connected to the inlet end of an external condenser, so that the generated gas can be condensed using the condenser. One end of the distillate discharge pipe 18 is fixedly connected to the feed end of an external condenser, so that the distilled fluid substance can be condensed, thereby achieving the function of separating and recovering the heavy components in the bromonitroethanol distillation residue.
[0027] In this embodiment, the pulverizing mechanism includes multiple pulverizing shafts 8, multiple pulverizing rollers 9, multiple gears 10, and a variable speed motor 11. The multiple pulverizing shafts 8 are rotatably mounted within the pulverizing chamber 2 and are evenly spaced. The multiple pulverizing rollers 9 are respectively fixedly mounted on their corresponding pulverizing shafts 8, and each pulverizing roller 9 has a plurality of evenly distributed pulverizing teeth fixedly mounted on it. The rear ends of the multiple pulverizing shafts 8 extend outside the bromonitroethanol distillation residue treatment box 1. The multiple gears 10 are respectively fixedly mounted on the rear ends of their corresponding pulverizing shafts 8, and the gears 10 mesh sequentially. The variable speed motor 11 is fixedly mounted in the bromonitroethanol distillation residue treatment box. On the front outer wall of 1, the output shaft end of the adjustable speed motor 11 is fixedly connected to the front end of one of the crushing shafts 8. The adjustable speed motor 11 can control the rotation of the crushing shaft 8 fixedly connected to its output shaft end. By using the meshing transmission action of multiple gears 10, multiple crushing shafts 8 can be controlled to rotate simultaneously, and the two adjacent crushing shafts 8 can rotate in opposite directions, thereby causing the two adjacent crushing rollers 9 to rotate in opposite directions. Under the joint action of multiple crushing rollers 9, the bromonitroethanol distillation residue can be crushed to reduce the particle size of the bromonitroethanol distillation residue, so as to facilitate faster distillation in the future.
[0028] In this embodiment, the sealing mechanism includes two electric telescopic rods 6 and two baffles 7. The two electric telescopic rods 6 are respectively fixedly installed on the left and right outer walls of the corresponding bromonitroethanol distillation residue treatment tank 1. The output shaft ends of the two electric telescopic rods 6 extend into the distillation chamber 3. The two baffles 7 are respectively fixedly installed on the output shaft ends of the corresponding electric telescopic rods 6. The sides of the two baffles 7 that are close to each other abut against each other, and the tops of the two baffles 7 slide in contact with the top inner wall of the distillation chamber 3. The two baffles 7 can completely seal the discharge hole 5. The telescopic feature of the two electric telescopic rods 6 can be used to control the horizontal linear movement of the two baffles 7 respectively.
[0029] In this embodiment, in order to make the baffle 7 fit better against the top inner wall of the distillation chamber 3, both the top surface of the baffle 7 and the top surface of the distillation chamber 3 are smooth planes.
[0030] In this embodiment, the material turning mechanism includes two turning shafts 20, multiple turning plates 21, two driving sprockets 22, two driven sprockets 23, and two chains 24. Both turning shafts 20 are rotatably mounted inside the distillation chamber 3 and located above the filter screen 12. The multiple turning plates 21 are fixedly mounted on the two turning shafts 20 and are evenly distributed. The rear ends of both turning shafts 20 extend outside the bromonitroethanol distillation residue treatment box 1. The two driving sprockets 22 are respectively fixedly mounted on the rear ends of two of the crushing shafts 8, and the two driven sprockets 23 are respectively... Fixedly mounted at the rear ends of the two turning shafts 20, two chains 24 are respectively mounted on the corresponding driving sprockets 22 and driven sprockets 23. By utilizing the meshing transmission action of the two sets of driving sprockets 22, driven sprockets 23 and chains 24, the two turning shafts 20 can be controlled to rotate simultaneously, thereby causing multiple turning plates 21 to rotate and stir the crushed bromonitroethanol distillation residue, enhancing the uniformity of heating of the bromonitroethanol distillation residue, improving the distillation effect and efficiency, and making the efficiency of refining heavy components of the bromonitroethanol distillation residue higher and the quality better.
[0031] In this embodiment, a pressure sensor 25 and a temperature sensor 26 are fixedly installed on the inner right side of the distillation chamber 3. The pressure sensor 25 is used to monitor the pressure value inside the distillation chamber 3, and the temperature sensor 26 is used to monitor the temperature value inside the distillation chamber 3. It should be noted that a controller is fixedly installed on the outer wall of the bromonitroethanol distillation residue treatment box 1. The controller is equipped with multiple control buttons and a display screen. The display screen is used to display the pressure value and temperature value monitored by the pressure sensor 25 and the temperature sensor 26. The multiple control buttons are used to control the opening and closing of the two electric telescopic rods 6, the adjustable speed motor 11, the first solenoid valve 17, the second solenoid valve 19, the pressure sensor 25, and the temperature sensor 26, respectively. The wiring connection method and control method are mature technologies in the field and are fully disclosed, so they will not be described in detail here.
[0032] In this embodiment, in order to facilitate the inspection and maintenance of the components inside the distillation chamber 3 and to facilitate the cleaning of the remaining residue on the filter screen 12, a cleaning port located above the turning shaft 20 is provided on the inner front wall of the distillation chamber 3. A cleaning door 27 is fixedly installed on the outer front wall of the bromonitroethanol distillation residue treatment box 1 by screws, and the cleaning door 27 is adapted to the cleaning port.
[0033] With the above structure, the apparatus for heavy component of bromonitroethanol distillation residue provided in this application, when in use...
[0034] The bromine nitrol distillation residue is fed into the crushing chamber 2 through the feeding hole, and then the sealing plug 4 is tightened in the feeding hole to seal it and prevent external impurities from entering or internal gas from leaking. Then, the adjustable speed motor 11 is started and controlled to have a suitable speed. With the sequential meshing of multiple gears 10, multiple crushing shafts 8 can be controlled to rotate simultaneously, and two adjacent crushing shafts 8 rotate in opposite directions. The crushing rollers 9 fixed on the crushing shafts 8 rotate accordingly. The crushing teeth on the crushing rollers 9 are used to crush the residue and reduce the particle size of the residue. This allows the residue to be heated and volatilized more quickly in the subsequent distillation process.
[0035] After the residue is crushed, by controlling the two electric telescopic rods 6 to retract and reset, the two baffles 7 can be controlled to move horizontally away from each other, thus opening the discharge hole 5. The crushed residue enters the distillation chamber 3 through the discharge hole 5 under the action of gravity.
[0036] After the residue falls into the distillation chamber 3, it will fall onto the upper surface of the filter screen 12. The filter screen 12 is an arc shape with a concave center, which can concentrate the residue in a certain area, making it easier for subsequent turning and distillation. Then, the electric heating tube 13 is activated to heat the inside of the distillation chamber 3. The electric heating tube 13 is temperature adjustable and can heat the inside of the distillation chamber 3 to a suitable temperature as needed, so that the heavy components in the residue will volatilize. At the same time, the booster pump 14 is activated to deliver pressurized air into the distillation chamber 3 through the exhaust pipe 15 to achieve pressurization and accelerate the volatilization rate of the heavy components. During the distillation process, the pressure sensor 25 and the temperature sensor 26 monitor the pressure and temperature values inside the distillation chamber 3 in real time and display the data on the display screen of the controller. The operator can control each device through the control buttons on the controller to ensure that the distillation process is carried out at a suitable pressure and temperature. The gas generated during the distillation process rises through the material discharge hole 5 and can be discharged through the distillation gas discharge pipe 16. The first solenoid valve 17 on the distillation gas discharge pipe 16 can control the discharge of gaseous substances.
[0037] During the distillation process, the meshing transmission of two sets of driving sprockets 22, driven sprockets 23 and chain 24 can control the simultaneous rotation of two turning shafts 20. Multiple turning plates 21 fixed on the turning shafts 20 rotate accordingly to turn and stir the crushed bromonitol distillation residue. The function of turning is to enhance the uniformity of the residue heating, improve the distillation effect and efficiency, and allow the heavy components in the residue to volatilize more fully. The distilled fluid substance passes through the filter holes on the filter screen 12 and can be discharged through the distillate discharge pipe 18. The second solenoid valve 19 on the distillate discharge pipe 18 can control the discharge of the fluid substance, thereby achieving the function of efficiently separating and recovering the heavy components in the bromonitol distillation residue.
[0038] After the residue distillation and heavy component treatment is completed, turn off the adjustable speed motor 11, booster pump 14, electric heating tube 13, pressure sensor 25 and temperature sensor 26, and remove the cleaning door 27 to clean out the remaining residue on the filter screen 12.
