Description

Technical Field

[0001] The invention relates to the technical field of feeding reactors, and in particular to a reactor for three-dimensional mixing of lime and nitrogen and a use method thereof. Background Art

[0002] A reactor is a device used for chemical reactions, usually in industries such as chemical engineering, petrochemicals, pharmaceuticals, and food processing. The main function of a reactor is to provide a closed environment for the reactants to ensure the control of the reaction process. A reactor is required for the preparation of lime nitrogen, and materials need to be added to the reactor during the preparation.

[0003] The current lime-nitrogen three-dimensional mixed feeding reactor does not have the function of monitoring the reaction of a single feeding during feeding, resulting in the next feeding before the ammonium cyanide and calcium oxide react completely after feeding. This not only causes an imbalance in the ratio of ammonium cyanide and calcium oxide, leading to unstable reaction conditions, but also causes the ammonium cyanide and calcium oxide to accumulate, resulting in incomplete reaction of ammonium cyanide and calcium oxide, reducing the effect of use. Therefore, it is urgent to design a reactor for lime-nitrogen three-dimensional mixed feeding. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art and to propose a reaction kettle for three-dimensional mixing of lime and nitrogen.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A reaction kettle for three-dimensional mixing of lime and nitrogen, comprising a barrel body, an air pipe connected to the surface of the barrel body, and further comprising:

[0007] A hollow column is vertically installed at the center of the top of the barrel, and the hollow column is connected to the barrel;

[0008] There are two automatic feeding components, which are symmetrically arranged on the top of the barrel body. The automatic feeding components are used to add raw materials for producing lime nitrogen into the barrel body;

[0009] The monitoring component is arranged inside the hollow column and on the barrel body, and the monitoring component is used to monitor the progress of preparing lime nitrogen inside the barrel body.

[0010] As a further technical solution of the present invention, the monitoring component includes: a piston disk, which is slidably arranged inside the hollow column, and a piston rod is vertically fixedly installed at the center of the top of the piston disk, and the top of the piston rod passes through the hollow column.

[0011] As a further technical solution of the present invention, a first spring is sleeved on the surface of the piston rod, and two ends of the first spring are respectively installed on the top of the piston disk and the top of the hollow column.

[0012] As a further technical solution of the present invention, a V-shaped plate is horizontally arranged above the hollow column, the top end of the piston rod is fixedly installed at one end of the bottom of the V-shaped plate, two symmetrically arranged telescopic rods are vertically fixed to the top of the barrel body, the telescopic ends of the two telescopic rods are fixedly installed at the bottom of the V-shaped plate, and two symmetrically arranged racks are vertically fixed to the bottom of the V-shaped plate.

[0013] As a further technical solution of the present invention, the automatic feeding assembly includes: a hopper, which is connected and installed on the top of the barrel body, a feeding roller is rotatably installed inside the end of the hopper, four annular storage grooves evenly distributed are opened on the surface of the feeding roller, and a second rotating rod is rotatably installed outside the hopper, and the end of the second rotating rod is fixedly installed at the center of the end face of the feeding roller through a connecting shaft.

[0014] As a further technical solution of the present invention, a first rotating rod is horizontally arranged above the barrel body, a mounting block is fixedly installed on the top of the barrel body, the surface of the first rotating rod is rotatably installed inside the mounting block, and a gear is fixedly installed on the top of the first rotating rod. When the gear and the rack are in contact, the gear and the rack mesh with each other.

[0015] As a further technical solution of the present invention, a turntable is rotatably installed at the end of the first rotating rod away from the gear, and the end of the second rotating rod away from the hopper is fixedly installed on the other side of the turntable. A fixed disk is fixedly sleeved on the surface of the first rotating rod, and a torsion spring is sleeved on the surface of the first rotating rod. Both ends of the torsion spring are respectively installed on the side of the fixed disk and the side of the turntable. Four L-shaped shift plates evenly distributed in a ring are also fixed on the surface of the first rotating rod.

[0016] As a further technical solution of the present invention, a horizontal groove is opened on the top of the barrel body, and an L-shaped baffle is arranged on the top of the barrel body. The end of the vertical side of the L-shaped baffle is slidably installed in the inside of the horizontal groove, and a spring rod is installed at the inner end of the horizontal groove. The telescopic end of the spring rod is fixedly installed on the side of the vertical side of the L-shaped baffle, and a ramp plate is fixedly installed on the side of the horizontal side of the L-shaped baffle. When the L-shaped shift plate and the ramp plate contact, the L-shaped shift plate slides between the ramp plate. Four circular and evenly distributed card plates are fixed on the side of the turntable away from the first rotating rod, and the L-shaped baffle is used to prevent the turntable from rotating together with the card plate.

[0017] As a further technical solution of the present invention, a heating rod is vertically rotatably installed at the bottom center of the barrel body, a plurality of evenly distributed stirring blades are horizontally fixed on the surface of the heating rod, a driving motor is installed at the bottom of the barrel body, and the output shaft of the driving motor is installed at the bottom center of the heating rod.

[0018] A method for using a reactor for three-dimensional mixing of lime and nitrogen, comprising the following steps:

[0019] S1: First, add ammonium cyanide and calcium oxide into the two hoppers respectively. It should be noted that the size of the storage tanks on the two unloading rollers is adapted to the ratio of the addition of ammonium cyanide and calcium oxide, so the ammonium cyanide and calcium oxide in the two hoppers will enter the corresponding storage tanks;

[0020] S2: Then, ammonia is injected twice into the barrel through the air pipe. It should be noted that the amount of ammonia injected twice is the same as the amount of ammonia generated by the subsequent reaction of ammonium cyanide and calcium oxide. When ammonia is injected into the barrel, the air pressure inside the barrel will increase, and the piston plate will move upward. The upward movement of the piston plate drives the piston rod to move upward and causes the first spring to generate elastic force. The upward movement of the piston rod drives the V-shaped plate to move upward. The movement of the V-shaped plate drives the two racks to move upward. The movement of the two racks drives the two gears to rotate. The rotation of the two gears drives the first rotating rod to rotate. The rotation of the first rotating rod drives the L-shaped dial plate and the fixed plate to rotate. The rotation of the fixed plate will cause The torsion spring generates torque. At this time, due to the setting of the L-shaped baffle and the card plate, the turntable will not rotate, and the torsion spring is always in a state of accumulating force. When all the ammonia gas is injected, the paddle passes over the ramp plate and moves the ramp plate. The movement of the ramp plate drives the L-shaped baffle plate to move and causes the spring rod to generate elastic force. After the L-shaped baffle plate moves, it will no longer hinder the corresponding card plate. The torsion force generated by the torsion spring will cause the turntable to rotate 90 degrees. The rotation of the turntable drives the second rotating rod to rotate. The rotation of the second rotating rod drives the unloading roller to rotate. In summary, the continuous injection of two ammonia gases can cause the unloading roller to rotate twice, and the ammonium cyanide and calcium oxide in the two hoppers will enter the barrel body.

[0021] S3: Ammonium cyanide and calcium oxide enter the barrel and are stirred by the heating rod and stirring blades, causing the ammonium cyanide and calcium oxide to react to generate lime nitrogen and ammonia. At this time, the ammonia generated inside the barrel will continue to increase the internal air pressure of the barrel. After the ammonium cyanide and calcium oxide react completely, the ammonia generated can make the unloading roller continue to rotate.

[0022] The beneficial effects of the present invention are:

[0023] Firstly, the present invention can automatically detect whether the raw materials fed once have reacted completely by setting the monitoring component and the automatic feeding component, and when the raw materials fed once have reacted completely, it will automatically feed again, thereby avoiding the situation that the next feeding is carried out before the ammonium cyanide and calcium oxide have reacted completely after feeding, causing the ammonium cyanide and calcium oxide to accumulate and causing the incomplete reaction of the ammonium cyanide and calcium oxide, thereby improving the use effect of the equipment;

[0024] Secondly, the present invention, through the arrangement of a monitoring component and an automatic feeding component, can prevent the turntable and the feed roller from rotating and causing the feed roller to discharge materials when the ammonium cyanide and calcium oxide inside the barrel body react. When the ammonium cyanide and calcium oxide inside the barrel body react completely to produce a sufficient amount of ammonia gas, the obstruction to the turntable is unlocked, so that the feed roller can rotate to discharge materials, thereby improving the use effect of the equipment.

[0041] Please refer to the attached Figure 1 -Attached Figure 7 In a preferred embodiment, a heating rod 16 is vertically rotatably installed at the bottom center of the barrel body 1, and a plurality of evenly distributed stirring blades are horizontally fixed on the surface of the heating rod 16. A driving motor 17 is installed at the bottom of the barrel body 1, and the output shaft of the driving motor 17 is installed at the bottom center of the heating rod 16.

[0042] Working principle of the present invention:

[0043] First, add ammonium cyanide and calcium oxide into the two hoppers 2 respectively. It should be noted that the size of the storage tanks on the two unloading rollers 18 is adapted to the ratio of the addition of ammonium cyanide and calcium oxide, so the ammonium cyanide and calcium oxide in the two hoppers 2 will enter the corresponding storage tanks;

[0044] Then, ammonia is injected into the barrel body 1 twice through the air pipe. It should be noted that the amount of ammonia injected twice is the same as the amount of ammonia generated when ammonium cyanide and calcium oxide react subsequently. After ammonia is injected into the barrel body 1, the air pressure inside the barrel body 1 will increase, and the piston plate 19 will move upward. The upward movement of the piston plate 19 drives the piston rod 20 to move upward and causes the first spring 21 to generate elastic force. The upward movement of the piston rod 20 drives the V-shaped plate 4 to move upward. The movement of the V-shaped plate 4 drives the two racks 6 to move upward. The movement of the two racks 6 drives the two gears 7 to rotate. The rotation of the two gears 7 drives the first rotating rod 8 to rotate. The rotation of the first rotating rod 8 drives the L-shaped dial plate 10 and the fixed plate 11 to rotate. The rotation of the fixed plate 11 causes the torsion spring 12 to generate torsion Force, at this time, due to the setting of the L-shaped baffle 23 and the card plate 22, the turntable 13 will not rotate, and the torsion spring 12 is always in a state of storing force. When the ammonia gas is fully injected, the paddle passes over the ramp plate 14 and moves the ramp plate 14. The movement of the ramp plate 14 drives the L-shaped baffle 23 to move and causes the spring rod 24 to generate elastic force. After the L-shaped baffle 23 moves, it will not hinder the corresponding card plate 22. The torsion force generated by the torsion spring 12 will cause the turntable 13 to rotate ninety degrees. The rotation of the turntable 13 drives the second rotating rod 9 to rotate. The rotation of the second rotating rod 9 drives the unloading roller 18 to rotate. In summary, the same reasoning applies to the above. Continuously injecting two ammonia gases can make the unloading roller 18 rotate twice, and the ammonium cyanide and calcium oxide in the two hoppers 2 will enter the barrel body 1.

[0045] Ammonium cyanide and calcium oxide enter the barrel body 1 and are stirred by the heating rod 16 and the stirring blades, so that the ammonium cyanide and calcium oxide react to generate lime nitrogen and ammonia. At this time, the ammonia generated in the barrel body 1 will continue to increase the air pressure in the barrel body 1. The ammonia generated after the ammonium cyanide and calcium oxide react completely can cause the unloading roller 18 to continue to rotate. In summary, the above reciprocating operation can automatically feed the material after the single addition of ammonium cyanide and calcium oxide react completely, avoiding excessive feeding, which not only causes an imbalance in the ratio of ammonium cyanide and calcium oxide, resulting in unstable reaction conditions, but also causes the accumulation of ammonium cyanide and calcium oxide, resulting in incomplete reaction of ammonium cyanide and calcium oxide, thereby improving the use effect of the equipment.

[0046] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

It should be noted that the size of the storage tanks on the two unloading rollers (18) is adapted to the ratio of the addition of ammonium cyanide and calcium oxide, so that the ammonium cyanide and calcium oxide in the two hoppers (2) will enter the corresponding storage tanks; S2: Ammonia is then injected into the barrel (1) twice through the air pipe. It should be noted that the amount of ammonia injected twice is the same as the amount of ammonia generated when the ammonium cyanide and calcium oxide react later. After ammonia is injected into the barrel (1), the air pressure inside the barrel (1) increases, and the piston plate (19) moves upward. The upward movement of the piston plate (19) drives the piston rod (20) to move upward and causes the first spring (21) to generate elastic force. The upward movement of the piston rod (20) drives the V-shaped plate (4) to move upward. The movement of the V-shaped plate (4) drives the two racks (6) to move upward. The movement of the two racks (6) drives the two gears (7) to rotate. The rotation of the two gears (7) drives the first rotating rod (8) to rotate.

After the L-shaped baffle (23) moves, it will not hinder the corresponding card plate (22). The torsion force generated by the torsion spring (12) will cause the turntable (13) to rotate ninety degrees. The rotation of the turntable (13) drives the second rotating rod (9) to rotate. The rotation of the second rotating rod (9) drives the unloading roller (18) to rotate. In summary, by the same logic, the unloading roller (18) can be rotated twice by continuously injecting two ammonia gases, and the ammonium cyanide and calcium oxide in the two hoppers (2) will enter the barrel (1). S3: Ammonium cyanide and calcium oxide enter the barrel (1) and are stirred by the heating rod (16) and the stirring blades, so that the ammonium cyanide and calcium oxide react to generate lime nitrogen and ammonia gas. At this time, the ammonia gas generated inside the barrel (1) will cause the internal air pressure of the barrel (1) to continue to increase. After the ammonium cyanide and calcium oxide react completely, the ammonia gas generated can cause the unloading roller (18) to continue to rotate.
