Description

Technical Field

[0001] The utility model relates to the technical field of sodium p-aminobenzenesulfonate, in particular to a centrifugal dehydration device for sodium p-aminobenzenesulfonate. Background Art

[0002] Sodium aminobenzenesulfonate: Toxic, swallowing or absorption through the skin can cause severe poisoning, but its toxicity is much lower than that of aniline and it is not carcinogenic. During the production process, it should be strictly prevented from accidental ingestion or splashing on the skin. The production equipment should be sealed to prevent leakage. Operators should wear protective equipment, keep the storage container sealed, and store it in a cool and dry place. Ensure that the workshop has good ventilation or exhaust devices, store it in a cool, ventilated and dry place, and protect it from heat, moisture and sun. It should be stored and transported according to the regulations for toxic substances. During production, it needs to be dried. For example, a disc dryer with application number CN201922489334.0 drives several first discs and several second discs thereon to rotate during the rotation of the central shaft. During the rotation of the first disc and the second disc, the harrow leaves on the first rake and the second rake stir the material on the first disc and the second disc, so that the sodium p-aminobenzenesulfonate on the first disc and the second disc is evenly heated, thereby achieving the purpose of uniform drying of the sodium p-aminobenzenesulfonate. The first disc and the second disc have different outer diameters, so that the dried sodium sulfanilate can be transferred from the upper disc and the first guide ring plate to the lower disc under the action of the centrifugal force of the upper disc, and finally fall into the discharge port. The arrangement of multiple first discs and second discs can prolong the residence time of the material in the machine body and on the discs, thereby achieving the purpose of drying the sodium sulfanilate with high drying efficiency.

DETAILED DESCRIPTION

[0018] 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.

[0019] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0020] When the sodium aminobenzenesulfonate drying device is in use, when there is too much liquid inside the sodium aminobenzenesulfonate, it cannot be centrifuged for dehydration and relies solely on evaporation for drying. This results in low drying efficiency and increases energy input, thereby increasing economic costs and causing inconvenience to the staff.

[0021] In view of this, the utility model provides a centrifugal dehydration device for sodium p-aminobenzenesulfonate. Through the cooperation of an outer tank, a centrifugal device, a feed hopper, a drying device, a first orifice plate, a second orifice plate and a torsion rod, when there is too much liquid inside the sodium p-aminobenzenesulfonate, centrifugal dehydration can be performed in advance, and then drying treatment can be performed, thereby greatly improving the drying efficiency and reducing the energy input. At the same time, the economic cost investment is reduced and the use of the staff is convenient.

[0022] Example 1: By Figure 1 、 2 , 3, 4 and 5 show that a centrifugal dehydration device for sodium p-aminobenzenesulfonate comprises an outer tank 1, a foot 5 is installed at the bottom of the outer tank 1, a tank cover 8 is installed above the outer tank 1, a feed hopper 9 is provided on one side of the tank cover 8, a drain pipe 6 is provided below one side of the outer tank 1, and a first cover 7 is provided on the side of the outer tank 1 away from the drain pipe 6. The centrifugal dehydration device for sodium p-aminobenzenesulfonate also includes: a centrifugal device 2, installed below the tank cover 8; a cleaning device 3, arranged above the centrifugal device 2; and a drying device 4, arranged inside the outer tank 1; wherein the centrifugal device 2 can realize centrifugal dehydration operation, the cleaning device 3 can quickly perform cleaning work after the centrifugal dehydration device for sodium p-aminobenzenesulfonate is used, and the drying device 4 can increase the drying speed of sodium p-aminobenzenesulfonate.

[0023] In the specific implementation process, it is worth noting that the external sodium aminobenzenesulfonate enters the interior of the centrifugal device 2 through the feed hopper 9, and then the centrifugal device 2 can be used for centrifugal dehydration, and the drying device 4 should be connected to the external air supply device, so that the hot air can be introduced into the interior of the outer tank 1, and the sodium aminobenzenesulfonate can be dried. The gas during drying can then be discharged through the exhaust pipe on the upper side of the outer tank 1. The cleaning device 3 is connected to the external water supply device, and the external cleaning water source can then enter the interior of the centrifugal device 2 for flushing;

[0024] Furthermore, a first orifice plate 11 is installed on the inner wall of the feed hopper 9, the bottom of the first orifice plate 11 is movably connected to a second orifice plate 10, and the top of the second orifice plate 10 is fixed with a torsion bar 12 that is rotatably connected to the inside of the first orifice plate 11 through a sealed bearing;

[0025] In the specific implementation process, it is worth noting that twisting the torsion bar 12 can change the position between the first orifice plate 11 and the second orifice plate 10, thereby enabling sealing during centrifugal dehydration of the centrifugal dehydration device for sodium p-aminobenzenesulfonate;

[0026] Specifically, when using the centrifugal dehydration equipment for sodium p-aminobenzenesulfonate, the staff first uses the feed hopper 9 to pour the material into the interior of the outer tank 1, and then uses the torsion bar 12 to change the position of the first orifice plate 11 and the second orifice plate 10, and then seals the feed hopper 9. The staff then turns on the external power supply of the centrifugal device 2. At this time, the centrifugal device 2 can perform centrifugal dehydration. When dehydration is completed, the staff uses the drying device 4 to introduce external heat into the interior of the centrifugal device 2, and at the same time slows down the rotation speed of the centrifugal device 2. At this time, the material can be dried. When drying is completed, the staff can open the first cover 7 and the second cover 203, and then the sodium p-aminobenzenesulfonate can be taken out. After taking out, and when the first cover 7 and the second cover 203 are reinstalled, the cleaning device 3 can be used to clean the centrifugal dehydration equipment for sodium p-aminobenzenesulfonate.

[0027] Example 2: By Figure 2 and 3It can be seen that the centrifugal device 2 includes: a servo motor 201, the model of the servo motor 201 is not specifically limited, and it can meet the use requirements and is detachably connected to the bottom of the outer tank 1; an inner tank 202, which is detachably connected to the output end of the servo motor 201, and is rotatably connected to the inner wall of the outer tank 1 and the tank cover 8 respectively through sealed bearings; two second covers 203 are provided, which are detachably connected to both sides of the inner tank 202; two sliders 204 are provided, which are respectively installed on both sides of the upper part of the inner tank 202; an annular slide rail 205 is installed above the inner wall of the outer tank 1, and is slidably engaged with the outer walls of the two sliders 204; wherein the servo motor 201 can drive the inner tank 202 to rotate, and the cooperation between the slider 204 and the annular slide rail 205 can limit the position of the inner tank 202;

[0028] In the specific implementation process, it is worth noting that the servo motor 201 can drive the inner tank 202 to rotate. At this time, as the inner tank 202 rotates, the material can be centrifugally dehydrated, and the slider 204 and the annular slide rail 205 cooperate to limit the inner tank 202, thereby ensuring its stability during rotation.

[0029] Specifically, based on the above-mentioned embodiment 1, when centrifugal dehydration is performed, the staff turns on the external power supply of the servo motor 201, and the servo motor 201 can drive the inner tank 202 to rotate. At this time, the inner tank 202 can drive the slider 204 to move along the inner wall of the annular slide rail 205, and then the material can be centrifugally dehydrated by the rotation of the inner tank 202.

[0030] Example 3: By Figure 2 and 4 As can be seen, the cleaning device 3 includes: a conduit 301 installed below the tank cover 8; a plurality of nozzles 302, each installed below the conduit 301; wherein external cleaning water can be transported through the conduit 301 and finally sprayed into the interior of the inner tank 202 from the nozzles 302;

[0031] In the specific implementation process, it is worth noting that the external water supply device can spray the cleaning water source into the interior of the inner tank 202 through the conduit 301 and the nozzle 302, thereby cleaning the interior of the inner tank 202;

[0032] Specifically, based on the above-mentioned embodiment 1 and embodiment 2, when cleaning work is required, the staff turns on the external water supply device connected to the conduit 301, and the external cleaning water source can enter the interior of the conduit 301, and then enter the interior of the inner tank 202 through the nozzle 302. At the same time, the staff turns on the external power supply of the centrifugal device 2. At this time, the inner tank 202 can be cleaned while the centrifugal force is used to clean the outer tank 1.

[0033] Example 4: By Figure 1 、 2 As shown in Figures 5 and 6, the drying device 4 includes: an air pipe 401, which is installed on the inner wall of the tank cover 8; a plurality of transverse pipes 402, which are all installed below the air pipe 401; and a plurality of one-way valves 403, which are respectively installed at the air outlets below the plurality of transverse pipes 402. The external drying gas can be input into the interior of the transverse pipe 402 through the air pipe 401 and then sprayed into the interior of the inner tank 202, thereby drying the sodium aminobenzenesulfonate.

[0034] In the specific implementation process, it is worth noting that the external air supply device can guide the drying hot air into the interior of the air pipe 401, and then blow it into the interior of the inner tank 202 through the exhaust port below the horizontal pipe 402, and the one-way valve 403 can prevent materials or liquids from entering the interior of the horizontal pipe 402.

[0035] Specifically, based on the above-mentioned embodiment 1 and embodiment 2, when drying the material, the staff turns on the external air supply device connected to the air pipe 401, and then the external hot air can enter the interior of the air pipe 401, and then be introduced into the interior of the cross pipe 402, and finally blown to the surface of the material through the one-way valve 403, thereby drying the material. When the rotation speed of the centrifugal device 2 slows down, due to the reduction of centrifugal force, the cross pipe 402 can also play a certain stirring role, thereby improving the drying efficiency.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
