At the same time, due to its bright color and low price, it is widely used in ink, plastic, rubber, coating, dye and other industries. Dichlorobenzidine hydrochloride needs to go through different processes in the production process to finally get the finished product we need.

[0003] At present, in the production process of dichlorobenzidine hydrochloride, since it contains solids, the dichlorobenzidine hydrochloride mother liquor needs to be subjected to a sedimentation operation to separate the solids in the mother liquor from the mother liquor.

[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0035] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, in one embodiment, a device for efficiently dissolving and separating dichlorobenzidine hydrochloride is provided, the device comprising:

[0036] The main body cylinder 1 comprises a fixed cylinder surface 101 arranged on the main body cylinder 1, and a mounting cover 102, a mother liquid outlet 103 and a solid outlet 104 are fixedly mounted on the surface of the fixed cylinder surface 101, and the mother liquid outlet 103 and the solid outlet 104 are communicated with the interior of the fixed cylinder surface 101, and valves are fixedly mounted on the mother liquid outlet 103 and the solid outlet 104;

[0037] Liquid inlet mechanism 2: comprises a movable pipe 201 installed inside the fixed cylinder surface 101, a flaring block 202 is fixedly installed on the surface of the movable pipe 201, and also comprises a plurality of sliding blocks 203 installed inside the fixed cylinder surface 101, and the surface of the sliding blocks 203 is set as a wave surface;

[0038] Pull rope mechanism 3: drives the moving pipe 201 to rise synchronously with the liquid level through the feedback signal of the feedback mechanism 6;

[0039] Pipeline mechanism 5: used for transporting mother liquid;

[0040] The back pressure mechanism 7 is used to drive the sliding block 203 to rotate from a vertical state to a horizontal state.

[0041] In practical application, when the mother liquor is settled, Figure 1 and Figure 6 As shown, at this time, the mother liquid flows into the mobile pipeline 201 through the pipeline mechanism 5, as shown in FIG. Figure 4 and Figure 7 As shown, the mother liquid diffuses inside the fixed cylinder surface 101 through the expansion block 202. Due to the increase in the space of the expansion block 202, the speed of flowing from the mobile pipe 201 to the inside of the fixed cylinder surface 101 is slowed down. At the same time, the blocking effect of the plurality of sliding blocks 203 reduces the fluctuation of the mother liquid when it diffuses inside the fixed cylinder surface 101. Moreover, the setting of the wave surface on the sliding block 203 makes the flowing mother liquid generate turbulence while being blocked by the sliding block 203, increasing the mutual impact between the flowing mother liquids, allowing the mother liquid to quickly tend to a flat state, thereby increasing the sedimentation efficiency and avoiding stirring of the solid matter. As the liquid level inside the fixed cylinder surface 101 rises, as shown in FIG. Figure 7 As shown, at this time, the pull rope mechanism 3 is driven to move under the feedback effect of the feedback mechanism 6, as shown in FIG. Figure 3 and Figure 5As shown in the figure, the movement of the pull rope mechanism 3 drives the mobile pipe 201 to rise synchronously, and then drives the flaring block 202 and the sliding block 203 to rise synchronously. Through the action of the telescopic spring 204, the sliding block 203 moves downward in the initial rising stage. At this time, the lower half of the sliding block 203 is located below the liquid surface. The mother liquid entering the fixed cylinder surface 101 from the flaring block 202 reduces the agitation of the lower mother liquid under the blocking action of the sliding block 203, thereby improving the sedimentation efficiency of the solid matter in the mother liquid. When the mother liquid in the fixed cylinder surface 101 is nearly full, as shown in FIG. Figure 8 and Fig. 9 As shown, at this time, the back-pressure mechanism 7 is driven to move by the squeezing effect of the mounting cover 102 on the back-pressure mechanism 7, and the movement of the back-pressure mechanism 7 drives the sliding block 203 to rotate, so that the sliding block 203 moves from a vertical state to a horizontal state. At this time, the sliding block 203 is flush with the liquid surface, thereby avoiding vibration caused by the operation of the equipment when the unfilled fixed cylinder surface 101 is filled, resulting in large fluctuations in the liquid surface, affecting the sedimentation efficiency of the solids. When the sedimentation is completed, the settled mother liquor is discharged through the mother liquor outlet 103, and the settled solids are discharged through the solid outlet 104. During the discharge process, the device is reset, thereby achieving the purpose of cyclic perfusion sedimentation.

[0042] like Figure 3 and Figure 5 As shown, as a preferred embodiment of the present invention, the pull rope mechanism 3 includes a moving slider 301 fixedly installed on the surface of the moving pipe 201, the moving slider 301 is slidably connected to the inner wall of the fixed cylinder surface 101, and a connecting pull rope 302 is fixedly installed on the surface of the moving slider 301, and the end of the connecting pull rope 302 away from the moving slider 301 is connected to the driving mechanism 4.

[0043] In practical application of the embodiment of the present invention, when the mother liquid is perfused, as shown in FIG. Figure 3 As shown, at this time, the feedback mechanism 6 drives the external drive to wind the connecting rope 302, as shown in FIG. Figure 5 As shown, from Figure 5 Looking from the front direction, the connecting pull rope 302 drives the movable slider 301 to move upward through the fixed pulley 303, thereby driving the movable pipe 201 to rise with the liquid level, so that the expansion block 202 is always close to the liquid surface during the liquid inlet process to avoid stirring the mother liquid in the lower layer.

[0044] like Figure 2 and Figure 3As shown, as another preferred embodiment of the present invention, the device also includes a driving mechanism 4, the driving mechanism 4 includes a driving motor 401 fixedly mounted on the mounting cover 102, the driving motor 401 is connected to the output end of the external controller, the output end of the driving motor 401 passes through the mounting cover 102 and is rotatably connected to the mounting cover 102, a driving turntable 402 is fixedly mounted on the output end of the driving motor 401, the surface of the connecting pull rope 302 is in contact with the surface of the fixed pulley 303, the fixed pulley 303 is rotatably connected to the surface of the mounting cover 102, the end of the connecting pull rope 302 away from the moving slider 301 is connected to the driving turntable 402, and the mounting cover 102 is provided with a small hole for the connecting pull rope 302 to pass through.

[0045] In practical application, when the embodiment of the present invention is subjected to the feedback effect of the feedback mechanism 6, as shown in FIG. Figure 3 As shown, at this time, the controller outputs a signal to the drive motor 401 so that the drive motor 401 starts to run. At this time, the operation of the drive motor 401 drives the drive turntable 402 to rotate. The rotation of the drive turntable 402 causes the connecting rope 302 to be wound around the drive turntable 402, thereby driving the mobile pipe 201 to move upward through the fixed pulley 303, ensuring that the expansion block 202 is always close to the liquid surface.

[0046] like Figure 6 As shown, as another preferred embodiment of the present invention, the pipeline mechanism 5 includes a fixed pipeline 501 that passes through the mounting cover 102 and is fixedly connected to the mounting cover 102, one end of the fixed pipeline 501 is connected to an external mother liquid conveying device, and a valve is provided on the fixed pipeline 501, the other end of the fixed pipeline 501 is connected to an elastic hose 502, the elastic hose 502 is arranged in a spiral shape, and the end of the elastic hose 502 away from the fixed pipeline 501 is connected to the mobile pipeline 201, and the interiors of the fixed pipeline 501, the elastic hose 502 and the mobile pipeline 201 are communicated.

[0047] In actual application of the embodiment of the present invention, when the mother liquid is poured into the fixed cylinder surface 101, the valve on the fixed pipeline 501 is opened, such as Figure 6 As shown, the mother liquid passes through the fixed pipe 501, the elastic hose 502 and the mobile pipe 201 and then flows from the expansion block 202 to the fixed cylinder surface 101. When the mobile pipe 201 rises, the elastic hose 502 contracts due to its spiral shape and the elasticity of the elastic hose 502 itself, thereby reducing the internal space occupied by the device and increasing the stability of the perfusion.

[0048] like Figure 7As shown, as another preferred embodiment of the present invention, the feedback mechanism 6 includes two buoyancy plates 601 slidably mounted on the surface of the flaring block 202, the surface of each buoyancy plate 601 is connected to the surface of the flaring block 202 through two extrusion springs 602, and the surface of each buoyancy plate 601 is fixedly mounted with two displacement columns 603, each displacement column 603 passes through the flaring block 202 and is slidably connected to the flaring block 202, and a displacement feedback device 604 is fixedly mounted on the surface of the flaring block 202, and the displacement feedback device 604 is connected to the input end of the external controller.

[0049] In practical application of the embodiment of the present invention, when pouring into the interior of the fixed cylinder surface 101, as shown in FIG. Figure 7 As shown, from Figure 7 Looking from the front direction, as the liquid level rises, the buoyancy drives the buoyancy plate 601 to move upward, and the upward movement of the buoyancy plate 601 drives the displacement column 603 to move upward. At this time, the displacement of the displacement column 603 is detected by the displacement feedback device 604, and the signal is fed back to the external controller. At this time, the external controller transmits the signal to the driving mechanism 4 to enable the driving mechanism 4 to operate. The operation of the driving mechanism 4 drives the expansion block 202 to move upward, and then drives the buoyancy plate 601 to move upward. By reducing the buoyancy, the displacement of the displacement column 603 tends to the initial state, thereby achieving the effect of stable feedback.

[0050] like Figure 8 , Fig.10 , Fig.11 As shown, as another preferred embodiment of the present invention, the back pressure mechanism 7 includes a back pressure ball head rod 701 installed in the fixed cylinder surface 101, the back pressure ball head rod 701 is fixedly installed on the follower disc 702, and a plurality of T-shaped push rods 704 are fixedly installed on the surface of the follower disc 702, the T-shaped push rod 704 passes through the connecting disc 703 and is slidably connected to the connecting disc 703, the follower disc 702 and the connecting disc 703 are connected by a reset spring 709, the mobile pipe 201 passes through the connecting disc 703 and is fixedly connected to the connecting disc 703, and the T-shaped push rod 70 4 penetrates through the cut cylinder 711 and is slidably connected with the cut cylinder 711, the T-shaped push rod 704 is connected with the cut cylinder 711 through the tension spring 710, a moving rack 705 is fixedly installed on the surface of the T-shaped push rod 704, the moving rack 705 is meshed with the rotating gear 706, a right-angle rotating rod 707 is coaxially fixedly installed on the inner wall of the rotating gear 706, the right-angle rotating rod 707 is rotatably connected with the cut cylinder 711, a linkage plate 708 is fixedly installed on the surface of the right-angle rotating rod 707, and the inner wall of the linkage plate 708 is connected with the sliding stopper 203 through the telescopic spring 204.

[0051] In actual application of the embodiment of the present invention, when the mother liquid is poured into the fixed cylinder surface 101 and is nearly full, Figure 8 As shown, from Figure 8 When viewed from the front, the moving pipe 201 moves upward, driving the back-pressure ball head rod 701 to contact the mounting cover 102. As the moving pipe 201 continues to rise, the back-pressure ball head rod 701 is driven downward by the reaction force of the mounting cover 102. The downward movement of the back-pressure ball head rod 701 drives the T-shaped push rod 704 to move downward through the follower disc 702, thereby driving the moving rack 705 to move downward, and driving the right-angle rotating rod 707 to rotate through the rack and gear transmission. The right-angle rotating rod 707 drives the sliding block 203 to rotate through the linkage plate 708, so that the sliding block 203 moves from a vertical state to a horizontal direction, thereby avoiding the vibration generated during the external perfusion causing the internal liquid level to fluctuate, affecting the sedimentation efficiency.

[0052] like Figure 4 As shown, as another preferred embodiment of the present invention, the device further includes a heating mechanism 8, and the heating mechanism 8 includes a plurality of heating rods 801 installed on the inner wall of the sliding stopper 203.

[0053] In practical application, when the mother liquor is being settled, Figure 4 As shown, at this time, the heating rod 801 heats the mother liquid at the liquid surface position, so that the viscosity of the mother liquid at the liquid surface position is reduced after being heated, and the sedimentation of the solid matter at the liquid surface position is accelerated, thereby achieving the purpose of improving the sedimentation efficiency.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
