Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of purification machines, in particular to a full-automatic low-temperature distillation solvent recovery purification machine. BACKGROUND

[0002] The low-temperature distillation solvent recovery purification machine is a device for recovering and purifying solvents under low temperature and low pressure conditions, which is mainly used for recovering and purifying solvents in chemical, pharmaceutical, electronic, environmental protection and other industries. The machine separates the solvents in the mixture by low-temperature distillation principle. Since the boiling point of a liquid decreases with the decrease of pressure, the pressure is reduced by creating a vacuum environment, so that the solvent can boil at a temperature much lower than the normal boiling point. Then it is cooled into a liquid by a condenser to achieve the purpose of recovery and purification, thereby realizing the recycling of solvents.

[0003] In the existing patent CN107737462A, an organic solvent recovery treatment device is disclosed, which comprises a base, a distillation tank and a steam generator. The distillation tank is fixed on the base. The upper part of the distillation tank is provided with a liquid inlet for waste solvent. The upper end of the distillation tank is provided with a condensing part. It also includes an air outlet cylinder, a rack, a motor, a hose and a screw rod. The output shaft of the motor is connected with a cam. One end of the screw rod is fixedly connected with the upper part of the distillation tank. The middle part of the air outlet cylinder is provided with a rotating shaft, and the middle part of the rotating shaft is provided with a screw thread. The rotating shaft is threadedly connected with the screw rod. The lower part of the rotating shaft is slidably connected with a rotating rod, and the rotating rod is not rotatable relative to the rotating shaft. The lower part of the rotating rod is provided with a gear, and the gear is engaged with the rack. The rack is slidably connected with the base. One end of the rack is connected with one end of a spring, and the other end of the spring is connected with the base. The air outlet cylinder is uniformly provided with a plurality of air outlet holes around the circumference. One end of the hose is in communication with the bottom of the air outlet cylinder, and the other end is in communication with the steam generator. The device can improve the distillation efficiency.

[0004] In the above structure, the distillation effect can be achieved. However, when the waste liquid is introduced into the recovery and purification machine, due to the influence of the low-pressure environment, the pressure difference will gradually decrease under natural conditions when the switch for introducing the waste liquid is opened, which affects the negative pressure environment of the recovery and purification machine. Due to the pressure difference between the positive and negative pressures, the waste liquid is forced to quickly enter the recovery and purification machine, which makes it difficult to control the amount of waste liquid entering. Once the distillation capacity of the machine is exceeded, the machine will run overload, greatly reducing the processing efficiency of the machine, and even causing the machine system to easily collapse, increasing the safety risk of the machine and reducing the service life of the device.

[0048] As shown in Figure 1 and Figure 10 The full-automatic low-temperature distillation solvent recovery purifier of the present application, the air extraction mechanism 12 comprises an air extraction pump 1201 installed on the bearing plate 1, the input end of the air extraction pump 1201 is provided with a conduit one 1202 in communication with the distillation cylinder 201, and the conduit one 1202 is provided with an electromagnetic valve one 1203.

[0049] As shown in Figure 1 and Figure 10 The full-automatic low-temperature distillation solvent recovery purifier of the present application, the air extraction mechanism 12 further comprises a conduit two 1204 provided on the input end of the air extraction pump 1201, the conduit two 1204 is provided with an electromagnetic valve two 1205, the conduit two 1204 penetrates the liquid storage cylinder 4, the inner wall of the liquid storage cylinder 4 is provided with a conversion pipe 1206 in communication with the conduit two 1204, the conversion pipe 1206 is provided with a suction pipe 1207 located in the inside of the control cylinder 7 and connected by a bearing, and the suction pipe 1207 penetrates the center of the control cylinder 7.

[0050] Working principle: the through port one 6 and the through port two 8 are closed, since the inlet pipe 5 is in communication with the waste liquid pipeline, the pressure of the waste liquid pipeline is in a positive pressure state, at this time, the waste liquid enters the liquid storage cylinder 4 through the inlet pipe 5, when it is necessary to recover the solvent of the waste liquid, the air extraction pump 1201 is started, the electromagnetic valve one 1203 and the electromagnetic valve two 1205 are opened, under the action of the conduit one 1202, the conduit two 1204 and the suction pipe 1207, the gas in the inside of the distillation cylinder 201 and the control cylinder 7 is forced to be extracted, forming a negative pressure state;

[0051] At this time, the pressure is less than the pressure in the balloon 1603, so that the balloon 1603 expands, since the control plate 1104 seals the sealing air bag 1601 in the space, under the action of the bend pipe 1602, the sealing air bag 1601 shrinks, forcing the sealing air bag 1601 to separate from the inner wall of the control cylinder 7;

[0052] Start hydraulic push rod 1101, the output end of hydraulic push rod 1101 drives rotating rod 1103 and support block 1102 movement, rotating rod 1103 drives control plate 1104 movement in control cylinder 7 to reasonable position, at this time control plate 1104 will control cylinder 7 is divided into two parts, realize the control to the quantity of waste liquid, simultaneously support block 1102 drives connection assembly 14 and rotating mechanism 13 synchronous movement;

[0053] When the waste liquid is passed, start motor 1 901, the output shaft of motor 1 901 rotates and drives the driving gear 902 to rotate, forcing the driven gear 903 to drive the control cylinder 7 to rotate until the inlet 1 6 and the inlet 2 8 are connected and communicated, and the suction pipe 1207 is rotated with the control cylinder 7, forcing the suction pipe 1207 to be located in the waste liquid upper empty position of the control cylinder 7;

[0054] Because the inside of the liquid storage cylinder 4 stores waste liquid, when the inlet 1 6 and the inlet 2 8 are communicated, because the pipeline of the waste liquid is normal atmospheric pressure, the waste liquid quickly enters the control cylinder 7 from the inlet 1 6 and the inlet 2 8, and because of the action of atmospheric pressure, the balloon 1603 smaller than atmospheric pressure is contracted, the balloon 1603 passes the bend pipe 1602 to communicate the sealed air bag 1601, forcing the sealed air bag 1601 to expand and resist the inner wall of the control cylinder 7, so that the control plate 1104 is firmly clamped at a certain position, improving the impact resistance of the control plate 1104, and the waste liquid continuously enters the control cylinder 7;

[0055] When the waste liquid reaches a certain amount, reverse start motor 1 901, the output shaft of motor 1 901 rotates and drives the driving gear 902 to rotate, forcing the driven gear 903 to drive the control cylinder 7 to rotate, the control cylinder 7 drives the control plate 1104 to rotate, and the suction pipe 1207 is rotated, forcing the inlet 1 6 and the inlet 2 8 to be closed;

[0056] Start electric push rod 1402, the output end of electric push rod 1402 drives connection frame 1403 movement, under the action of support frame 1401, make the connection frame 1403 drive the sliding sleeve 1404 movement, so as to force the friction sleeve 1405 movement, because the inside and outside of the friction sleeve 1405 have friction, until the friction sleeve 1405 and the rotating rod 1103 and the sleeve 1303 are connected together to form an integral whole;

[0057] The motor two 1301 is started, the output shaft of the motor two 1301 rotates and drives the main bevel gear to rotate, so that the driven bevel gear 1304 rotates, the driven bevel gear 1304 rotates and drives the sleeve 1303 to rotate, under the friction of the friction sleeve 1405, the rotating rod 1103 is forced to rotate, the rotating rod 1103 rotates and drives the stirring rod 1501 to rotate, the stirring rod 1501 drives the stirring blade 1502 to rotate, so that the waste liquid is stirred, the gas in the waste liquid is escaped, and the waste liquid is moved, reducing the accumulation of waste residues in the waste liquid;

[0058] Since the atmosphere continuously enters the control cylinder 7 with the waste liquid, the air pressure in the control cylinder 7 needs to be controlled, the electromagnetic valve one 1203 is closed, the electromagnetic valve two 1205 is opened, and the air pump 1201 is started, under the action of the conduit two 1204, the conversion pipe 1206 and the air suction pipe 1207, the gas in the control cylinder 7 is continuously pumped out, until the air pressure in the control cylinder 7 is equal to the air pressure in the distillation cylinder 201;

[0059] Since the air pressure in the control cylinder 7 is less than the air pressure in the balloon 1603, the balloon 1603 gradually expands, so that the sealing air bag 1601 contracts, and the sealing air bag 1601 separates from the inner wall of the control cylinder 7, when the pressures on both sides of the control plate 1104 are equal, the sealing air bag 1601 just separates from the control cylinder 7;

[0060] When the quantitative waste liquid is introduced into the distillation cylinder 201, the motor two 1301 is stopped, the stirring rod 1501 is forced to stop rotating, the hydraulic push rod 1101 is started in reverse, the output end of the hydraulic push rod 1101 drives the rotating rod 1103 and the supporting block 1102 to retreat, the rotating rod 1103 drives the control plate 1104, the stirring rod 1501 and the stirring blade 1502 to retreat, until the control plate 1104 passes through the communication pipe 202, under the action of gravity, the waste liquid enters the distillation cylinder 201, the waste liquid in the distillation cylinder 201 is distilled, so that the solvent is evaporated into the condenser 203 and condensed to form the solvent, which is output through the output pipe 204 for recycling, and the above process is repeated to continuously automatically process the quantitative waste liquid;

[0061] The setting of the distillation assembly 2 purifies and recycles the waste liquid, so that the solvent is evaporated and condensed for recycling, facilitating the treatment of the solvent, improving the efficiency of solvent recovery, and achieving the purpose of automatic recovery of the solvent; The setting of the adjusting mechanism 9 facilitates the rotation of the control cylinder 7, thereby adjusting the communication and closure of the through port one 6 and the through port two 8, thereby utilizing the effect of air pressure to achieve the purpose of automatic suction of the waste liquid, and enabling the device to operate normally; The setting of the control assembly 11 can achieve precise control of the control plate 1104, so that the control plate 1104 moves back and forth in the control cylinder 7, thereby forming a control space between the control cylinder 7 and the control plate 1104, achieving quantitative control of the waste liquid, improving the processing efficiency of the device, ensuring stable operation of the device, reducing the safety risk of the device, and prolonging the service life of the device.

[0062] The scheme forms the effect of low-temperature distillation through low pressure, realizes the full-automatic effect of the device from the process of feeding the waste liquid to recycling the solvent, feeds the waste liquid by using the air pressure difference, guides the waste liquid into the distillation cylinder 201 by using gravity, controls the amount of the waste liquid, realizes the effect of quantitative distillation of the waste liquid, improves the processing efficiency of the device, guarantees the stable operation of the device, reduces the safety risk of the device, and improves the service life of the device.

[0063] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
