DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-3 The utility model provides a technical solution: an impurity removal and separation device for chlorinated paraffin production, comprising a device tank 1 with an open top, an upper cover plate 2 detachably mounted on the top of the device tank 1, a connecting ring 5 fixedly connected to the middle portion of the bottom end of the upper cover plate 2, a mesh cylinder 6 whose bottom end extends to the bottom of the device tank 1 is vertically fixedly connected to the bottom end of the connecting ring 5, and a stirring blade 8 is vertically rotatably connected to the bottom end of the device tank 1;
[0019] The outer surface of the device tank 1 is fixedly connected to a spacer frame 3, and an annular cavity is formed between the spacer frame 3 and the device tank 1. A heating wire 4 is arranged inside the cavity. The side surface of the inner cavity of the device tank 1 is connected to a plurality of blowing pipes 11 that extend obliquely to the bottom end of the inner part of the device tank 1. A mounting opening is opened horizontally through the outer surface of the spacer frame 3, and a mounting ring 12 is fixedly connected to the inside of the mounting opening. A plurality of connecting rods 13 extending toward the center of its cross-section are fixedly connected to the inside of the mounting ring 12. The inner ends of the plurality of connecting rods 13 are fixedly connected to fixing plates 14, and the inner end of the fixing plate 14 is connected to an exhaust fan for horizontal rotation.
[0020] When the device is actually used, solid chlorinated paraffin is installed inside the mesh tube 6 and the upper cover plate 2 is installed on the top of the device tank 1. Then the electric heating wire 4 outside the device tank 1 starts to heat up, and the solid paraffin will melt and drip downward from the mesh tube 6. At the same time, the stirring blade 8 starts to rotate, accelerating the volatilization rate of hydrogen chloride in the chlorinated paraffin, thereby improving the overall impurity removal efficiency. After the entire impurity removal operation is completed, the solid impurities will remain inside the mesh tube 6, so that the device can remove solid impurities while removing hydrogen chloride, thereby improving the practicality of the device.
[0021] During the operation of the device, the exhaust fan will continue to rotate, drawing external air into the cavity for heating, and then under the action of air pressure, the hot air is sent into the liquid chlorinated paraffin inside the device tank 1 through multiple blowing pipes 11, further increasing the volatilization rate of hydrogen chloride.
[0022] The upper cover plate 2 of the device is a detachable structure. After the chlorinated paraffin is treated, the upper cover plate 2 is removed and the net tube 6 is removed from below the connecting ring 5 so that the substances attached to the net tube 6 can be cleaned.
[0023] The bottom end of the device tank 1 is fixedly connected to a first motor 7 , and the output shaft of the first motor 7 rotatably passes through the device tank 1 and is fixedly connected to the bottom end of the stirring blade 8 .
[0024] When the first motor 7 is running, it drives the stirring blade 8 to rotate, thereby stirring the liquid chlorinated paraffin and accelerating the volatilization speed of hydrogen chloride.
[0025] A second motor 15 is fixedly connected to the outer end surface of the fixing plate 14 . The output shaft of the second motor 15 rotatably passes through the fixing plate 14 and is fixedly connected to the rotating shaft of the exhaust fan. A filter 16 is fixedly connected to the interior of the mounting ring 12 .
[0026] The second motor 15 drives the exhaust fan to rotate, and the filter 16 can prevent impurities such as dust in the air from entering the interior of the device and causing pollution to the chlorinated paraffin.
[0027] The lower surface of the upper cover plate 2 is vertically connected to an exhaust pipe 9 extending to the lower part of the device tank 1 , and the upper surface of the upper cover plate 2 is fixedly connected to an air outlet hose 10 connected to the exhaust pipe 9 .
[0028] The amount of chlorinated paraffin processed by the device each time is fixed. When the chlorinated paraffin is completely melted into liquid, the top of the liquid level is located below the exhaust pipe 9. Since the density of hydrogen chloride is greater than that of air, the air will move upward after entering the device, and the hydrogen chloride produced by volatilization will be located between the air and the chlorinated paraffin. Under the action of continuous volatilization and air injection, the pressure in the tank will increase. Under the action of pressure, the hydrogen chloride in the middle part will flow upward through the exhaust pipe 9 and be discharged through the air outlet hose 10.
[0029] The other end of the air outlet hose 10 will be placed in clean water. Hydrogen chloride is easily soluble in water, so the discharged hydrogen chloride will directly dissolve in the water and will not leak out directly to cause pollution.
[0030] The bottom end of the device tank 1 is vertically connected to a discharge pipe 17 , and a solenoid valve 18 is provided on the discharge pipe 17 .
[0031] After the impurity removal operation is completed, the solenoid valve 18 can be opened to discharge the liquid chlorinated paraffin from the discharge pipe 17.
[0032] A plurality of supporting legs 19 are vertically fixedly connected to the bottom end of the device tank 1 .
[0033] The multiple supporting legs 19 all play a supporting role.
[0034] When the device is actually used, solid chlorinated paraffin is installed inside the mesh tube 6 and the upper cover plate 2 is installed on the top of the device tank 1. Then the electric heating wire 4 outside the device tank 1 starts to heat up, and the solid paraffin will melt and drip downward from the mesh tube 6. At the same time, the stirring blade 8 starts to rotate, accelerating the volatilization rate of hydrogen chloride in the chlorinated paraffin, thereby improving the overall impurity removal efficiency. After the entire impurity removal operation is completed, the solid impurities will remain inside the mesh tube 6, so that the device can remove solid impurities while removing hydrogen chloride, thereby improving the practicality of the device.
