Description

Technical Field

[0001] This utility model relates to the field of polyaluminum production technology, and in particular to a polyaluminum chloride reaction vessel. Background Technology

[0002] Polyaluminum chloride, or polyaluminum for short, is a water-soluble inorganic polymer that is widely used as an emerging water purification material and coagulant in the purification and treatment of drinking water, industrial wastewater, and municipal sewage. The polyaluminum chloride reactor is an essential piece of equipment in the production process of polyaluminum chloride, and its main function is to achieve the mixing, reaction, and separation of raw materials and products.

[0003] A reaction vessel for polyaluminum chloride is disclosed in Chinese Patent Publication No. CN221085596U. This reaction vessel for polyaluminum chloride improves stirring efficiency by installing a telescopic cylinder at the top of the reaction vessel and adjusting the up-and-down movement of the stirring motor using the telescopic cylinder, so that the stirring arm moves up and down while rotating. However, according to the reaction vessels for polyaluminum chloride provided by related technologies and existing technologies, traditional reaction vessels usually adopt gravity discharge method. This discharge method is inefficient and slow. At the same time, unreacted solid raw materials in the vessel are prone to deposit near the discharge port, which can cause blockage of the discharge channel and affect the normal feeding of the reaction vessel.

[0010] Preferably, the feed tube is V-shaped, and the threaded sleeve is located at the V-shaped corner of the feed tube.

[0011] Beneficial effects:

[0012] This polyaluminum chloride reactor, by setting up a discharge component, a conveying component, and a control component, allows the push rod to push the rotating shaft upward during the process of opening the cover, achieving frictional linkage with the stirring shaft, which in turn drives the spiral blade to rotate, quickly discharging the material in the reactor through the discharge pipe, thus improving the discharge speed. At the same time, the spiral blade can unclog the discharge pipe during rotation, preventing the accumulation of solid material in the reactor and blocking the discharge pipe, ensuring a smooth discharge process.

[0023] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0024] like Figures 1 to 7As shown, a polyaluminum chloride reactor includes a reactor body 1, a reactor cover 2 fixedly mounted on the top of the reactor body 1, a drive unit 4 fixedly mounted at the center of the reactor cover 2, a stirring shaft 5 mounted on the output end of the drive unit 4, multiple stirring blades 3 fixedly mounted on the stirring shaft 5, a discharge assembly 6 for discharging materials fixedly mounted at the bottom of the reactor body 1, a conveying assembly 8 for opening the discharge assembly 6 and spirally conveying materials in conjunction with the stirring shaft 5, and a control assembly 7 for controlling the linkage state between the conveying assembly 8 and the stirring shaft 5 at the bottom of the discharge assembly 6. The control assembly 7 uses... The control unit 6 controls the opening and closing of the discharge component 6. In use, the raw materials are added into the vessel body 1. Then, the vessel cover 2 supports the drive unit 4, which drives the stirring shaft 5 to rotate the stirring blades 3 to stir and mix the raw materials, accelerating the reaction inside the vessel body 1. After the reaction is completed, the stirring is stopped, and the pressure inside the vessel body 1 is released. Then, the control component 7 pushes the conveying component 8 upward to open the discharge component 6. At the same time, the conveying component 8 and the stirring shaft 5 are linked together. At this time, the stirring shaft 5 rotates again and synchronously drives the conveying component 8 to rotate. The spiral pushes the material to accelerate the discharge and improve the discharge speed.

[0025] like Figure 5 and Figure 6 As shown, the discharge assembly 6 includes a fixed plate 61 fixed to the bottom of the vessel body 1. A discharge pipe 62 is fixedly provided at the bottom of the fixed plate 61. A through hole 63 is provided at the center of the fixed plate 61. A sealing groove 64 is provided at the top edge of the through hole 63. A sealing gasket 65 is fixedly provided at the bottom of the sealing groove 64. The discharge pipe 62 is fixed to the bottom of the vessel body 1 through the fixed plate 61 and communicates with the inside of the vessel body 1 through the through hole 63. During the reaction, the conveying assembly 8 presses the sealing gasket 65 and cooperates with the sealing groove 64 to close the discharge pipe 62.

[0026] like Figure 2 and Figure 6 As shown, the control component 7 includes a threaded sleeve 71 that fixes the bottom of the feed tube 62. A push rod 72 is inserted through the threaded sleeve 71. The top of the push rod 72 extends into the feed tube 62 and is rotatably mounted with a connecting block 74. A handwheel 73 is fixedly mounted at the bottom of the push rod 72. The feed tube 62 is V-shaped, and the threaded sleeve 71 is located at the V-shaped corner of the feed tube 62. By rotating the push rod 72 with the handwheel 73, the push rod 72, under the action of the threaded sleeve 71, pushes the conveying component 8 up and down through the connecting block 74, thereby controlling the opening and closing of the feed tube 62.

[0027] like Figures 5 to 7As shown, the conveying assembly 8 includes a rotating shaft 83 fixed to the top of the connecting block 74. A spiral blade 84 is fixedly provided at the bottom of the rotating shaft 83. A cover plate 81 is rotatably installed at the position corresponding to the sealing groove 64 on the rotating shaft 83. A protective sleeve 82 is rotatably installed on the top of the cover plate 81. The protective sleeve 82 is slidably connected to the rotating shaft 83. A lower friction plate 85 is fixedly provided at the top of the rotating shaft 83, and an upper friction plate 86 is fixedly provided at the bottom of the stirring shaft 5. After the reaction is completed, stirring is stopped, and the pressure inside the vessel 1 is released. Then, the push rod 72 is rotated by the handwheel 73. Under the action of the threaded sleeve 71, the push rod 72 pushes the rotating shaft 83 through the connecting block 74, causing the pressure plate to move upward and disengage from the sealing groove 64, thus lowering the pressure plate. The top of the feed pipe 62 opens, and at the same time, the rotating shaft 83 will drive the lower friction plate 85 inside the sheath 82 to move upward until it comes into close contact with the upper friction plate 86 at the bottom of the stirring shaft 5, thus linking the rotating shaft 83 and the stirring shaft 5 through friction. At this time, the stirring shaft 5 is rotated again, and the stirring shaft 5 drives the rotating shaft 83 and the spiral blade 84 to rotate through friction, thereby conveying the material in the vessel 1 out through the feed pipe 62, accelerating the discharge of the material and increasing the discharge speed. At the same time, the rotating spiral blade 84 can also agitate the solid material deposited near the discharge port, allowing it to be discharged smoothly with the liquid, and clearing the feed pipe 62 to prevent blockage.

[0028] The work process is as follows:

[0029] S1: As Figure 1 As shown, when in use, the raw materials are added into the vessel body 1, and then the vessel cover 2 supports the drive unit 4 to drive the stirring shaft 5 to rotate the stirring blade 3, which stirs and mixes the raw materials and accelerates the reaction in the vessel body 1.

[0030] S2: As Figure 1 As shown, after the reaction is complete, stop stirring and depressurize the inside of vessel 1;

[0031] S3: As Figures 5 to 7 As shown, the push rod 72 is then rotated by the handwheel 73. Under the action of the threaded sleeve 71, the push rod 72 pushes the rotating shaft 83 through the connecting block 74, causing the pressure plate to move upward and disengage from the sealing groove 64, thus opening the top of the feed pipe 62.

[0032] S4: As Figures 5 to 7 As shown, at the same time, the rotating shaft 83 will also drive the lower friction plate 85 inside the sheath 82 to move upward until it comes into close contact with the upper friction plate 86 at the bottom of the stirring shaft 5, thus linking the rotating shaft 83 and the stirring shaft 5 together through friction.

[0033] S5: As Figure 7 As shown, at this time, the stirring shaft 5 is rotated again, and the stirring shaft 5 drives the rotating shaft 83 and the spiral blade 84 to rotate through friction, thereby conveying the material in the vessel 1 to the outside through the feed pipe 62, accelerating the discharge of the material and increasing the discharge speed.

[0034] S6: As Figure 7 As shown, the rotating spiral blade 84 can also agitate the solid material deposited near the discharge port, allowing it to be discharged smoothly along with the liquid, and clear the discharge pipe 62 to prevent it from becoming blocked.

[0035] In this application, the vessel body 1 and the drive unit 4 are known technologies in this field, therefore their specific structures and working principles are not described in detail.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
