Description

Technical Field

[0001] The utility model relates to the technical field of sodium hydrosulfide multi-stage reaction, in particular to a sodium hydrosulfide multi-stage reaction device. Background Art

[0002] Sodium hydrosulfide multi-stage reaction refers to the process of continuous reaction of sodium sulfide under different conditions. Sodium hydrosulfide is a commonly used sulfide that can be used in water treatment, metal extraction, chemical synthesis and other fields. The sodium hydrosulfide multi-stage reaction device usually includes multiple reactors and pipelines and other equipment to achieve efficient reaction of sodium hydrosulfide.

[0003] The existing related technologies often have the following defects: when using a transmission tube to connect multiple reactors together, the transmission tube is usually inserted into the reactor, and then the transmission tube is connected to the reactor by welding. The welding connection is inconvenient to disassemble the transmission tube for maintenance and cleaning, so it is easy to cause the transmission tube to be blocked or aged, affecting the operating effect.

[0004] Therefore, the utility model provides a sodium hydrosulfide multi-stage reaction device. Utility Model Content

[0005] The utility model aims to solve the disadvantage in the prior art that it is inconvenient to disassemble the transmission pipe for maintenance and cleaning due to the welding connection, and proposes a sodium hydrosulfide multi-stage reaction device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sodium hydrosulfide multi-stage reaction device, comprising a reactor and a reactor cover, the surface of the reactor is connected with a feed pipe, the surface of the reactor is connected with a transmission pipe, the surface of the reactor is provided with a limiting structure, the limiting structure comprises a fixed plate, the fixed plate is fixedly connected to the surface of the reactor, the surface of the fixed plate is rotatably connected with a bidirectional screw, the surface of the bidirectional screw is threadedly connected with two driving arms, the two driving arms are fixedly connected with a clamping plate on one side close to each other, and the size of the clamping plate is adapted to the size of the transmission pipe.

[0007] The effect achieved by the above components is: by setting a limiting structure, it is convenient to limit the transmission tube inserted into the reactor, thereby avoiding the need to use welding when using the transmission tube to connect the reactor, and then facilitating the disassembly of the transmission tube for maintenance and cleaning, thereby improving the reaction effect of sodium hydrosulfide.

[0008] Preferably, a round rod is slidably penetrated through the surface of the driving arm, and the round rod is fixedly connected to the surface of the fixing plate.

[0009] The effect achieved by the above components is that the driving arm will slide along the surface of the round rod when it moves, and the round rod limits the moving path of the driving arm, thereby preventing the driving arm from rotating when it moves.

[0010] Preferably, one end of the bidirectional screw is fixedly connected to a rectangular rod, and one end of the rectangular rod away from the bidirectional screw is fixedly connected to a rotating disk.

[0011] The effects achieved by the above components are: the rotation of the turntable drives the rectangular rod to rotate, and the rotation of the rectangular rod drives the bidirectional screw to rotate, so that the turntable facilitates the rotation of the bidirectional screw.

[0012] Preferably, a plurality of anti-slip strips are fixedly connected to one side of the two clamping plates close to each other, and the plurality of anti-slip strips are all made of rubber material.

[0013] The effect achieved by the above components is that the splint drives the anti-slip strip to fit tightly against the surface of the transmission tube, and the anti-slip strip increases the friction between the splint and the transmission tube, thereby further improving the effect of limiting the transmission tube.

[0014] Preferably, a support structure is provided on the surface of the reactor, and the support structure includes a rotating shaft, which is fixedly connected to the surface of the reactor, and the arc surface of the rotating shaft is rotatably connected to a support arm, and the support arm is fixedly connected to the arc surface of a reactor cover, and two circular holes are provided on the surface of the support arm, and one end of the rotating shaft away from the reactor is fixedly connected to a top plate, and a pin is slidably penetrated through the surface of the top plate, and the size of the pin is adapted to the size of the circular hole.

[0016] Preferably, the arc surface of the latch is sleeved with a spring, and two ends of the spring are fixedly connected to the latch and the top plate respectively.

[0017] The effect achieved by the above components is that the bolt is inserted into the round hole with the help of the contraction force of the spring, and the spring improves the stability of the bolt inserted into the round hole, thereby preventing the bolt from falling out of the round hole due to shaking.

[0018] Preferably, the arc surface of the rotating shaft is fixedly connected to a limit plate, the inner wall of the limit plate is slidably connected to a limit rod, and the limit rod is fixedly connected to the support arm.

[0019] The effect achieved by the above components is that when the support arm rotates, it drives the limit rod to slide in the limit plate, and the limit plate reaches the limit rotation angle of the limit rod, thereby limiting the rotation angle of the kettle cover.

[0020] In summary:

[0021] 1. In the utility model, by setting a limiting structure, when it is necessary to limit the transmission tube inserted into the reactor, first rotate the bidirectional screw. The rotation of the bidirectional screw will drive the two driving arms to move towards each other with the help of the thread. The driving arm will drive the clamping plate to move when moving. The clamping plate will move towards the direction close to the transmission tube when moving. When the clamping plate moves to a suitable position, the clamping plate will fit tightly on the surface of the transmission tube, thereby limiting the transmission tube, making it easier to disassemble the transmission tube for maintenance and cleaning, thereby improving the reaction effect of sodium hydrosulfide.

[0022] 2. In the utility model, by setting a supporting structure, the kettle cover can be rotated. The rotation of the kettle cover will drive the support arm to rotate on the surface of the rotating shaft. When the kettle cover is rotated to a suitable position, the latch is pressed and the latch is inserted into the circular hole, thereby limiting the position of the support arm and supporting the position of the kettle cover, thereby avoiding the need to place the kettle cover on the ground when opening the reactor, thereby reducing the effect of contamination of the kettle cover.

[0029] Reference Figure 1As shown, the utility model provides a technical solution: a sodium hydrosulfide multi-stage reaction device, including a reactor 1 and a reactor cover 3, the surface of the reactor 1 is connected with a feed pipe 2, the surface of the reactor 1 is connected with a transmission pipe 4, and the surface of the reactor 1 is provided with a limiting structure 5. By setting the limiting structure 5, it is convenient to limit the transmission pipe 4 inserted into the reactor 1, thereby avoiding the need to use welding when the transmission pipe 4 is used to connect the reactor 1, and then facilitating the disassembly of the transmission pipe 4 for maintenance and cleaning, thereby improving the reaction effect of sodium hydrosulfide. The surface of the reactor 1 is provided with a supporting structure 6. By setting the supporting structure 6, it is convenient to support the reactor cover 3 when the reactor 1 is opened, thereby avoiding the need to place the reactor cover 3 on the ground, thereby reducing the effect of the reactor cover 3 being contaminated.

[0030] The specific arrangement and function of the limiting structure 5 and the supporting structure 6 will be described in detail below.

[0031] Reference Figure 3 and Figure 4 As shown, in this embodiment: the limiting structure 5 includes a fixed plate 51, the fixed plate 51 is fixedly connected to the surface of the reactor 1, the surface of the fixed plate 51 is rotatably connected to a bidirectional screw 52, ​​the surface of the bidirectional screw 52 is threadedly connected to two driving arms 53, and the two driving arms 53 are fixedly connected to a clamping plate 54 on the side close to each other, and the size of the clamping plate 54 is adapted to the size of the transmission tube 4. A round rod 55 is slidably penetrated through the surface of the driving arm 53, and the round rod 55 is fixedly connected to the surface of the fixed plate 51. The driving arm 53 moves and slides along the surface of the round rod 55. The round rod 55 has the effect of limiting the moving path of the driving arm 53, thereby preventing the driving arm 53 from rotating when moving. A rectangular rod 56 is fixedly connected to one end of the bidirectional screw 52, ​​and a rotating disk 57 is fixedly connected to the end of the rectangular rod 56 away from the bidirectional screw 52. The rotation of the rotating disk 57 drives the rectangular rod 56 to rotate, and the rotation of the rectangular rod 56 drives the bidirectional screw 52 to rotate. The rotating disk 57 has the effect of facilitating the rotation of the bidirectional screw 52. A plurality of anti-slip strips 58 are fixedly connected to one side of the two splints 54 close to each other. The anti-slip strips 58 are all made of rubber material. The splints 54 will drive the anti-slip strips 58 to fit tightly against the surface of the transmission tube 4. The anti-slip strips 58 increase the friction between the splints 54 and the transmission tube 4, thereby further improving the effect of limiting the transmission tube 4.

[0032] Reference Figure 2 and Figure 5As shown, specifically, the support structure 6 includes a rotating shaft 61, which is fixedly connected to the surface of the reactor 1, and the arc surface of the rotating shaft 61 is rotatably connected to a support arm 62, which is fixedly connected to the arc surface of the reactor cover 3, and the surface of the support arm 62 is provided with two circular holes 65. The end of the rotating shaft 61 away from the reactor 1 is fixedly connected to a top plate 63, and the surface of the top plate 63 is slidably penetrated by a latch 64, and the size of the latch 64 is adapted to the size of the circular hole 65. The arc surface of the latch 64 is sleeved with a spring 66, and the two ends of the spring 66 are respectively fixedly connected to the latch 64 and the top plate 63. The latch 64 will be inserted into the circular hole 65 with the help of the contraction force of the spring 66, and the spring 66 can improve the stability of the latch 64 inserted into the circular hole 65, thereby preventing the latch 64 from falling out of the circular hole 65 due to shaking. The arc surface of the rotating shaft 61 is fixedly connected to the limit plate 67, and the inner wall of the limit plate 67 is slidably connected to the limit rod 68. The limit rod 68 is fixedly connected to the support arm 62. When the support arm 62 rotates, it will drive the limit rod 68 to slide in the limit plate 67. The limit plate 67 reaches the limit rotation angle of the limit rod 68, thereby limiting the rotation angle of the kettle cover 3.

[0033] Working principle: when it is necessary to limit the transmission tube 4 inserted into the reactor 1, first rotate the turntable 57. The rotation of the turntable 57 will drive the rectangular rod 56 to rotate. The rotation of the rectangular rod 56 will drive the bidirectional screw 52 to rotate. The rotation of the bidirectional screw 52 will rotate in the fixed plate 51. The rotation of the bidirectional screw 52 will drive the two driving arms 53 to move in the direction of approaching each other with the help of the thread. The movement of the driving arm 53 will slide along the surface of the round rod 55. The round rod 55 can limit the movement path of the driving arm 53, thereby preventing the driving arm 53 from rotating when moving. The driving arm 53 will drive the clamping plate 54 to move when moving. The clamping plate 54 will move in the direction close to the transmission tube 4 when moving. When the clamping plate 54 moves to a suitable position, the clamping plate 54 will drive the anti-slip strip 58 to fit closely on the surface of the transmission tube 4, thereby limiting the transmission tube 4. The anti-slip strip 58 can increase the friction between the clamping plate 54 and the transmission tube 4, thereby further improving the effect of limiting the transmission tube 4.

[0034] When it is necessary to support the lid 3 of the opened reactor 1, first pull the latch 64. The latch 64 will slide in the top plate 63 and gradually come out of the circular hole 65 when it moves. The latch 64 will stretch the spring 66 when it moves. When the latch 64 comes out of the circular hole 65, the spring 66 is in a stretched state. Then rotate the reactor cover 3. The rotation of the reactor cover 3 will drive the support arm 62 to rotate on the surface of the rotating shaft 61. The support arm 62 will drive the limit rod 68 to slide in the limit plate 67 when it rotates. The limit plate 67 reaches the limit rotation angle of the limit rod 68, thereby limiting the rotation angle of the reactor cover 3. When the reactor cover 3 is rotated to a suitable position, release the latch 64. The latch 64 will be inserted into the circular hole 65 with the help of the contraction force of the spring 66, thereby limiting the position of the support arm 62, and then supporting the position of the reactor cover 3, thereby avoiding the need to place the reactor cover 3 on the ground when opening the reactor 1.
