Description

Technical Field

[0001] The invention relates to the technical field of sodium carboxymethyl cellulose production equipment, and more specifically to a chloride removal device for sodium carboxymethyl cellulose production. Background Art

[0002] Chloride is a by-product of the production process of sodium carboxymethyl cellulose (CMC sodium salt for short). These by-products come out together with the product. After multiple washings, these water-soluble chlorides will be washed away, and the purity of the product will be higher. Therefore, the greater the chloride, the less pure the product. The viscosity of the product will decrease. After the production is completed, the manufacturer will determine the substitution degree and chloride content in the sodium carboxymethyl cellulose (CMC sodium salt for short) product.

[0003] After the production of sodium carboxymethyl cellulose is completed, the chloride inside needs to be separated and removed. Usually, the produced sodium carboxymethyl cellulose is washed several times, and then methanol solution is added to the sodium carboxymethyl cellulose. Then the chloride removal equipment separates the solid material and the methanol washing solvent. The separated material is a relatively pure sodium carboxymethyl cellulose. The removal equipment structure usually uses a spiral centrifugal device to separate the solid material and the methanol washing solvent. The spiral fan blade structure of the spiral centrifugal device is easy to clog during use, and it is more troublesome to clean. Summary of the invention

[0009] Furthermore, spiral blades are arranged on the outer side of the inner core of the drum, and a pair of centrifugal grooves are opened in the middle of the drum shell.

[0010] By adopting the above technical solution, the inner core of the drum can be rotated to cooperate with the drum shell, so as to separate the esterified sodium carboxymethyl cellulose and the methanol washing solvent, which is convenient for subsequent processing.

[0025] 2.

The drum core 29 rotates to cooperate with the drum shell 28, thereby separating the esterified sodium carboxymethyl cellulose and the methanol washing solvent, which is convenient for subsequent processing.

[0043] The end of the protection pipe 17 away from the protection outer shell 18 is fixedly installed with a connecting box 2, the middle of the connecting box 2 is fixedly installed with a connecting pipe 26, the upper end of the connecting pipe 26 is fixedly installed with a raw material box 1, the upper end of the connecting pipe 26 passes through the upper wall of the connecting box 2 and is fixedly installed with the raw material box 1, the other end of the connecting pipe 26 is fixedly connected to the inner cavity side wall of the connecting box 2 close to the protection pipe 17, a circular through groove is provided in the middle of the end of the drum inner core 29 close to the protection pipe 17, and an injection pipe 27 is fixedly installed at the end of the connecting pipe 26 close to the drum inner core 29, the injection pipe 27 passes through the through groove provided in the drum inner core 29 and extends to the inside of the drum inner core 29 to connect the filling pipe 16 with the feeding device, the mixed material enters the inside of the raw material box 1 in advance, and the connecting pipe 26 can directly inject the mixed liquid of the mixed sodium carboxymethyl cellulose and the methanol washing solvent into the inside of the drum inner core 29 through the injection pipe 27 to realize uninterrupted injection separation;

[0044] A first electric valve 601 is fixedly installed on the lower side of the inner cavity of the discharge pipe 6, a second electric valve 7 is fixedly installed in the middle of the connecting water pipe 8, the liquid inlet end of the high-pressure water pump 9 extends to the inside of the connecting water tank 10, and the liquid outlet end of the high-pressure water pump 9 is fixedly connected to the connecting water pipe 8. The inside of the discharge pipe 6 can be closed by the first electric valve 601, and the inside of the connecting water tank 10 is filled with cleaning liquid. The cleaning liquid in the connecting water tank 10 can be pumped from the connecting water pipe 8 into the discharge pipe 6 through the high-pressure water pump 9, so that the inside of the drum inner core 29 can be cleaned;

[0045] The upper end of the support member 12 penetrates the protective outer shell 18 and is fixedly mounted with a stabilizing bearing 1201, which is rotatably connected to the drum shell 28. When the drum shell 28 rotates, the stabilizing bearing 1201 can play a certain supporting and stabilizing role on the drum shell 28, reducing the vibration of the drum shell 28 during the rotation process, thereby effectively reducing the noise of the device and increasing the stability of use;

[0046] The fixed base 14 is provided with a stabilizing member 24 at the output end of the stepping motor 25 and the driving shaft 23. The stabilizing member 24 can play a certain role in stabilizing, reinforcing and preventing dust from the connection position, thereby increasing the stability of use;

[0047] The drum inner core 29 and the filter inner shell 31 are rotatably connected via the connecting bearing 33, and the filter outer shell 30 and the rotating shaft 36 are rotatably connected via the first rotating shaft 3001. During the rotation of the drum inner core 29, the filter inner shell 31 is synchronously driven to rotate under the action of the internal friction force. During the high-speed rotation of the rotating shaft 36, the filter outer shell 30 is synchronously driven to rotate. Since the drum inner core 29 and the rotating shaft 36 have a differential speed, the filter inner shell 31 and the filter outer shell 30, which are respectively rotatably connected thereto, have different connection states.

[0048] The inner cavity of the drum shell 28 is a gradually narrowing frustoconical structure, and the inner cavity diameter at one end of the turbine outer shell 21 is larger than the inner cavity diameter at one end of the protective pipe 17. When the drum shell 28 rotates at a high speed, the inner core 29 of the drum rotates at a low speed. At this time, under the action of centrifugal force, the internal methanol washing solvent will be separated from the sodium carboxymethyl cellulose, and the methanol washing solvent will move toward the end close to the turbine outer shell 21 under the action of centrifugal force.

[0049] The working principle of the present invention is as follows: the installer injects the esterified sodium carboxymethyl cellulose mixture into the interior of the raw material box 1 through the filling pipe 16, and then starts the servo motor 3 and the stepper motor 25. The servo motor 3 drives the first driving wheel 5 to rotate, and the first driving wheel 5 drives the second driving wheel 501 to rotate synchronously through the driving belt 4. Since the second driving wheel 501 is fixedly installed on the drum core 29, the drum core 29 will rotate inside the protective outer shell 18. The stepper motor 25 drives the turbine blades 2101 to rotate through the driving shaft 23. The turbine blades 2101 rotate the drum shell 28 synchronously through the rotating shaft 36 and the synchronous rotating member 34. Finally, the drum core 29 and the drum shell 28 rotate in the same direction, and the rotation speed of the drum shell 28 is greater than that of the drum core 29. As the sodium carboxymethyl cellulose mixture enters along the injection pipe 27, To the inside of the drum core 29, since the drum core 29 is in a rotating state, the sodium carboxymethyl cellulose mixture will be thrown out from the position of the centrifugal groove 2901 under the action of centrifugal force, and enter between the drum core 29 and the drum shell 28. Since the inner cavity of the drum shell 28 is a gradually narrowing truncated cone structure, the inner cavity diameter at one end of the turbine outer shell 21 is larger than the inner cavity diameter at one end of the protection pipe 17, and the rotation speed of the drum core 29 is lower than that of the drum shell 28. At this time, the methanol washing solvent in the sodium carboxymethyl cellulose mixture gradually moves toward the turbine outer shell 21 under the action of centrifugal force, and the separated sodium carboxymethyl cellulose will gradually move toward the protection pipe 17 under the rotation of the outer blades of the drum core 29. Finally, the separated sodium carboxymethyl cellulose is discharged from the position of the discharge pipe 6, and a sodium carboxymethyl cellulose product with higher purity can be obtained;

[0050] according to Fig. 9As shown, when the sodium carboxymethyl cellulose mixed material is separated, the drum core 29 and the filter inner shell 31 are driven to rotate through the connecting bearing 33. When the rotating shaft 36 rotates, the filter outer shell 30 is driven to rotate through the first rotating shaft 3001. At this time, the overall rotation rate of the filter outer shell 30 is greater than the rotation rate of the filter inner shell 31, so that the second filter plate 32 in the middle of the first filter frame 3201 is attached to the first filter plate 3102 and rotates synchronously. When the methanol washing solvent is centrifuged to the position of the filter inner shell 31, it enters the turbine outer shell 21 through the second filter plate 32 and the first filter plate 3102. The methanol washing solvent is discharged from the second connecting port 20 under the action of the negative pressure generated when the turbine blades 2101 rotate. The second filter plate 32 and the first filter plate 3102 can effectively prevent the sodium carboxymethyl cellulose raw material from being lost along with the methanol washing solvent during the separation process.

[0051] according to Fig.10 As shown, when the device needs to be cleaned after being used for a period of time, a cleaning solvent is injected into the interior of the connecting water tank 10, the first electric valve 601 is closed, and the servo motor 3 is started to rotate the drum core 29. As the filter inner shell 31 rotates, the second fan-shaped groove 3101 and the filter outer shell 30 are aligned. Then the servo motor 3 is closed, and the cleaning solvent is pumped into the space between the drum core 29 and the drum shell 28 through the connecting water pipe 8 and the discharge pipe 6. The cleaning solvent is reversely poured into the space between the drum core 29 and the drum shell 28, which can have a certain impact on the blocked sodium carboxymethyl cellulose to loosen it, thereby Some blocked materials are washed to the side of the inner filter shell 31 along with the cleaning agent, and some mixed waste and internal residues are washed into the position of the water seal plate 35 from between the second fan-shaped groove 3101 and the outer filter shell 30. After flushing for a period of time, the stepper motor 25 is started, and water is discharged outward at the second connection port 20 to discharge the waste at the position of the water seal plate 35. At the same time, the first filter plate 3102 and the second filter plate 32 prevent the mixed materials from re-entering the interior of the drum shell 28, so that the overall device can be cleaned and discharged more conveniently without affecting the good filtering effect during normal use.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
