Description

Technical Field

[0001] The utility model relates to a mixer, in particular to a horizontal solid-liquid mixer, belonging to the technical field of powder mixing equipment. Background Art

[0002] In many fields, it is often necessary to mix two materials. A traditional mixer includes a base, a shell is installed on the base, and the shell envelope forms a mixing chamber. Two mixing rotor shafts rotating in opposite directions are arranged in the mixing chamber. The driving ends of the two mixing rotor shafts extend out of the shell and are respectively installed with rotor shaft sprockets. A driving motor is installed on one side of the shell, and a driving sprocket is installed on the output shaft of the driving motor. The driving sprocket drives the two rotor shaft sprockets to rotate in opposite directions through a chain, and drives the two mixing rotor shafts to rotate in opposite directions to mix the materials evenly. Traditional mixers are developed based on the mixing of two solid powder materials or granular materials, and are not very suitable for mixing solid powder materials or granular materials with liquid materials.

[0003] The Chinese invention patent with the publication number CN 116603415B discloses a horizontal solid-liquid mixer for catalyst raw materials, including a mixing assembly, and a material storage assembly is arranged at the top of the mixing assembly. Through the arrangement of the stirring assembly, the central stirring shaft, the inner stirring plate, the stirring sleeve, the outer stirring plate, the upper fixed cylinder, the upper bevel gear, the side bevel gear and the lower bevel gear, it is intended to solve the problem of low stirring efficiency caused by the single structure of the existing horizontal solid-liquid mixer. Under the mutual bite of the upper bevel gear, the side bevel gear and the lower bevel gear, the stirring sleeve and the central stirring shaft can rotate in opposite directions. At this time, if the stirring sleeve rotates clockwise, the central stirring shaft rotates counterclockwise, and then the outer stirring plate can be driven to rotate in the opposite direction to the inner stirring plate, which can play a role in sufficient mixing.

[0004] The horizontal solid-liquid mixer is vertical, and different materials are fed into the tank through different feed ports and mixed by stirring. Since the liquid is not evenly distributed in the tank, most of the liquid phase material is absorbed by the solid powder that first contacts it, and the uniformity and sufficiency of the mixing are relatively poor. It takes a long time of stirring to make the powder relatively uniform, and the processing efficiency is poor. Utility Model Content

[0042] In the following description of the utility model, the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not mean that the device must have a specific direction.

[0043] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific figures. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0045] like Figures 1 to 9 As shown, the horizontal solid-liquid mixer of the utility model comprises a base 15, a driving motor 12, a coupling 13, a barrel 1 and a rotating rotor. The two ends of the barrel 1 are respectively provided with end plates 2 for closing the ports, and the bottoms of the end plates 2 extend downward and are respectively supported on the base 15. A feed port 1a is provided above the feed end of the barrel 1. The feed port 1a is offset and the outer side of the lower end of the feed port is tangent to the barrel 1, so that the solid new material directly enters the mixing chamber of the barrel 1 to avoid discharging the material at the rotating shaft 3. A discharge port 1b is provided below the discharge end of the barrel 1. The outer port of the discharge port 1b extends obliquely downward and the bottom wall of the discharge port is tangent to the bottom of the barrel, forming a volute shape for discharging to one side, so that the mixed material is discharged from the discharge port 1b.

[0046] The rotating rotor is located in the inner cavity of the cylinder 1, and includes a rotating shaft 3 coaxial with the cylinder. Both ends of the rotating shaft 3 pass through the center of the corresponding end plate 2 and are supported on the base 15 through bearing seats 14 respectively. The driving end of the rotating shaft 3 is located at the end where the discharge port 1b is located, and is connected to the rotor shaft of the driving motor 12 through a coupling 13. The bottom of the driving motor 12 is fixed on the base 15.

[0047] The cylinder 1 is composed of two halves, the upper and lower halves are fixedly connected by flanges on both sides of the upper and lower halves, and one side of the upper half is hinged to the same side of the lower half through a chain pin 1c and a hinged ear. When there is material blockage or maintenance is required, after removing all bolts connecting the flange, the unhinged side of the upper half can be opened and rotated around the chain pin 1c until it is completely opened.

[0048] The part of the rotating shaft 3 located in the inner cavity of the cylinder is provided with a feed propulsion section, a liquid spray mixing section and a mixing propulsion section in sequence along the axial direction. The feed propulsion section is located below the feed port 1a. The feed propulsion section is provided with a feed blade 4 on the circumference close to the end plate 2 to propel the newly entered powder material to the liquid spray mixing section. The rotating shaft optical axis section is between the feed blade 4 and the liquid spray mixing section, which facilitates the material from the upper feed port 1a to fall into the inner cavity of the cylinder on the one hand, and prevents the new powder material from entering the liquid spray mixing section too fast on the other hand, which is conducive to sufficient mixing.

[0049] The liquid spraying and mixing section is entered after passing the bottom of the feed port 1a. A plurality of stirring liquid spraying rods 5 pointing radially to the inner wall of the cylinder are evenly arranged on the circumference of the rotating shaft of the liquid spraying and mixing section. The stirring liquid spraying rods 5 are evenly arranged in multiple groups along the axial direction of the liquid spraying and mixing section, for example, five groups. The outer wall of each stirring liquid spraying rod 5 is evenly arranged with multiple spray holes 5b. The spray holes 5b of the same group are evenly distributed on the same cross section of the stirring liquid spraying rod 5. The spray holes 5b of each group are also evenly distributed along the axial direction of the stirring liquid spraying rod 5; the inner port of each spray hole 5b is respectively connected to the central channel 5a of the liquid spraying rod, and the inlet of the central channel 5a of each liquid spraying rod is respectively connected to the central channel of the rotating shaft 3. The inlet end of the central channel 3a of the rotating shaft is equipped with a rotary joint 11, and the rotary joint 11 is located at the feed end of the rotating shaft 3.

[0050] The stirring spray rod 5 can be a prism extending along the radial direction of the cylinder, for example, a regular triangular prism, each corner of the regular triangular prism is further provided with a cutting surface to form a hexagonal prism, and the spray holes 5b are evenly arranged on each cutting surface.

[0051] The traditional structure also has a solution of setting spray holes on the rotating shaft. On the one hand, the number of spray holes is relatively small and the distribution area is small; on the other hand, liquid can only be sprayed to a smaller annular space close to the rotating shaft, and most of the annular space close to the inner wall of the cylinder cannot be exposed to the spray liquid. The area of ​​the outer ring is much larger than that of the inner ring. Once the liquid material is absorbed by the powder, it is difficult to transfer it to other powders, and the problem of being caught in the powder is inevitable.

[0052] When the mixer is working, the powdered material enters the inner cavity of the cylinder from the feed port 1a at one end of the cylinder under the action of slight negative pressure; the liquid such as reagent or solution enters the central hole 3a of the rotating shaft axially from the rotating joint 11, and then enters the central hole 5a of each spray rod radially, and finally sprays out from each spray hole in a mist form and is evenly mixed with the powder from the feed propulsion section. Each stirring and spraying rod 5 of the mixer is deeply inserted into the material, and the end of the stirring and spraying rod 5 is close to the inner wall of the barrel 1. The spray holes 5b on the stirring and spraying rod 5 spray liquid in each cross section, each radius and each direction, firstly ensuring that the reagent or solution is evenly sprayed on the solid powder, and all powder particles can be sprayed with mist droplets; in addition, the stirring and spraying rod 5 has a strong stirring effect, and the propulsion of the material in the spraying and mixing section still relies on the pushing blade 6 at the head end of the feed propulsion section, so that the powder passes through the spraying and mixing section at a slow speed, and is fully stirred and sprayed by the stirring and spraying rods 5 at each end surface, so as to achieve uniform mixing of the reagent or solution and the solid powder.

[0053] A plurality of pusher blades 6 are arranged in sequence along the spiral line in the material advancing direction on the circumference of the mixing and advancing section, and a stirring rod 7 pointing to the inner wall of the cylinder is also arranged on the circumference where each pusher blade 6 of the mixing and advancing section is located. The pusher blades 6 pick up the powder after spraying and stirring and push it toward the discharge port 1b, and at the same time, multiple strong stirrings are still performed, so that the powder after spraying is further mixed and evenly discharged from the discharge port 1b quickly.

[0054] The stirring rod 7 can adopt the same shape as the stirring spray rod 5, except that the central channel 5a and the spray hole of the spray rod are not processed, which is convenient for unified processing and reduces manufacturing costs.

[0055] The rotating shaft 3 is symmetrically provided with cutting surfaces at four phases, each cutting surface extending from the liquid spraying and mixing section to the mixing and pushing section, so as to facilitate fixing each stirring liquid spraying rod 5, the pushing blade 6 and the stirring rod 7 on the cutting surface.

[0056] The driving motor 12 drives the rotating rotor to rotate at a high speed of more than 1500r / min through the coupling 13. Under the action of centrifugal force, liquids such as reagents or solutions are sprayed into the entire space of the inner cavity of the shell. During the process of the solid powder material turning over and moving forward in the cavity, it evenly absorbs the mist liquid, thereby achieving full and uniform mixing of the solid powder material and the sprayed mist liquid.

[0057] Since the rotating shaft 3 rotates at a high speed of 1500r / min, the sealing of the shaft ends on both sides adopts an air seal + labyrinth seal to ensure no leakage; the shaft end liquid inlet is connected to the feed pipe using a rotary joint 11 to ensure no leakage at the interface during high-speed rotation.

[0058] like Figure 4 , Figure 5As shown, a rotating material blocking disk 8 is respectively provided on the inner side of the inner end surface of the two end plates 2, and the center of the rotating material blocking disk 8 is respectively fixed on the rotating shaft 3. The rotating material blocking disk 8 prevents the material from approaching the rotating shaft 3 and passing through the sealing area of ​​the center hole of the end plate, thereby forming a first seal; a small amount of material that passes over the rotating material blocking disk 8 is not subjected to axial thrust due to the obstruction of the rotating material blocking disk 8, and re-enters the material flow from the lower edge of the rotating material blocking disk 8.

[0059] A rotating sealing block 10 is respectively provided in the center holes of the two end plates 2. The rotating sealing block 10 is fixed on the rotating shaft 3 and rotates at high speed with the rotating shaft 3. The outer edge of the rotating sealing block 10 and the inner edge of the center hole of the corresponding end plate are zigzag, forming an axial labyrinth seal as a second seal.

[0060] The outer side of the center hole of the two end plates 2 is provided with a gas seal 9 as the third seal. The gas seal 9 includes a static ring 9a and a dynamic ring 9b that cooperate with each other. The static ring 9a is fixed on the outer end surface of the end plate 2 and the inner stop is embedded in the center hole of the end plate 2; the dynamic ring 9b is located in the center hole of the static ring 9a, the inner circumference of the dynamic ring 9b is sleeved on the rotating shaft 3, and the inner circumferential wall of the dynamic ring 9b is embedded with multiple dynamic ring seals 9c to achieve sealing with the rotating shaft 3. A pair of gas seal rings 9d are embedded in the inner wall of the center hole of the static ring 9a, and the lip of the gas seal ring 9d is against the outer wall of the dynamic ring 9b; an injection channel 9a2 is provided between the two gas seal rings 9d, and an injection port 9a1 is provided on the outer end surface of the static ring 9a to communicate with the injection channel 9a2. Through the injection port 9a1, gas less than 0.1MPa is injected into the injection channel 9a2, so that the lip of the gas seal ring 9d is reliably attached to the outer wall of the dynamic ring 9b to ensure reliable sealing.

[0061] The above description is only the preferred feasible embodiment of the utility model, which shows and describes the basic principle, main features and advantages of the utility model, but does not limit the scope of patent protection of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. In addition to the above embodiments, the utility model can also have other implementation modes without departing from the spirit and scope of the utility model. The utility model will also have various changes and improvements. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the utility model. The scope of protection required by the utility model is defined by the attached claims and their equivalents. The technical features not described in the utility model can be achieved by or using existing technologies, which will not be repeated here.
