Description

Technical Field

[0001] The utility model relates to the technical field of cyclone separation, in particular to a cyclone separation device. Background Art

[0002] The cyclone separator is a commonly used separation device that uses the effect of cyclones to separate particulate matter from gas. Its working principle is to use the gas to generate a rotating motion inside the cyclone separator, so that the particulate matter is separated by the centrifugal force, and the clean gas is discharged from the top of the cyclone separator. Cyclone separators are widely used in industrial production to separate solid materials such as dust and particulate matter from gas.

[0003] CN211384358U discloses a cyclone separator, comprising a cylindrical ash hopper, a connecting pipe, a separator cone, a separator cylinder, an air inlet pipe connected to the side wall of the separator cylinder, an exhaust pipe with one end extending from the top of the separator cylinder, and a porous filter tube arranged in the separator cylinder and connected to the end of the exhaust pipe; the inner walls of the air inlet pipe and the exhaust pipe are both provided with a tortoise shell mesh, and the tortoise shell mesh is covered with a wear-resistant layer.

[0004] The above technical solution can well solve the problems of the existing cyclone separators, such as the gas-solid separation efficiency is not ideal, and the intake pipe and exhaust pipe are prone to serious wear after long-term use. However, in some cases, the cyclone separator is not only required to separate gas and solid, but also to separate different particle sizes in solid particles. The above technical solution cannot separate different particle sizes. Utility Model Content

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Example 1

[0015] refer to Figures 1 to 3 A cyclone separation device comprises a separation tank body 1 and a plurality of collecting assemblies 2, wherein a plurality of coaxially arranged discharge pipes 11 are provided at the bottom of the separation tank body 1, discharge gaps 12 are provided between the plurality of discharge pipes 11, and inlet ends of the plurality of discharge pipes 11 are gradually lowered from outside to inside, the discharge gaps 12 are communicated with the interior of the separation tank body 1, the plurality of collecting assemblies 2 are respectively detachably connected to the plurality of discharge pipes 11, and accommodating cavities 22 are provided between the plurality of collecting assemblies 2.

[0016] Under this design, particles will enter the separation tank body 1 under the action of an external air source, and then a cyclone will be generated under the action of the separation tank body 1. Particles with larger particle sizes are less affected by the cyclone, so they will fall directly from the corresponding discharge pipe into the collection component 2 under the action of their own gravity; particles with medium particle sizes will be affected by the cyclone, because the separation tank body 1 is a conical structure, and the space in the upper part is larger than the space in the lower part, so when entering the separation tank body 1, they will not contact the tank wall of the separation tank body 1, but will contact the tank wall of the separation tank body 1 when moving close to the corresponding discharge pipe under the action of the cyclone and their own gravity, and enter the corresponding collection component 2 from the corresponding discharge gap 12. The smaller particles will contact the tank wall under the action of the cyclone when entering the separation tank body 1, and enter the corresponding collection component 2 from the corresponding discharge gap 12. The separation of particle sizes is achieved.

[0017] In this embodiment, there are three discharge pipes 11, namely a first discharge pipe 111, a second discharge pipe 112, and a third discharge pipe 113. The first discharge pipe 111 is connected to the bottom of the separation tank body 1, the second discharge pipe 112 is connected in the first discharge pipe 111, and the third discharge pipe 113 is connected in the second discharge pipe 112. A discharge gap 12 is provided between the first discharge pipe 111 and the second discharge pipe 112, and between the second discharge pipe 112 and the third discharge pipe 113. The inlet ends of the first discharge pipe 111, the second discharge pipe 112, and the third discharge pipe 113 are successively lowered, and the multiple collecting components 2 are respectively connected to the first discharge pipe 111, the second discharge pipe 112, and the third discharge pipe 113.

[0018] In actual work, because the first discharge pipe 111 is connected to the bottom of the separation tank body 1 and the inlet end of the first discharge pipe 111 is the highest, the first discharge pipe 111 is used to guide particles with smaller particle size into the corresponding accommodating chamber 22 of the collection assembly 2. Under the action of the cyclone, particles with smaller particle size will directly stick to the tank wall of the separation tank body 1 and move downward along the tank wall. When they move to the inlet end of the first discharge pipe 111, they will pass through the corresponding discharge gap 12 for discharge.

[0019] The height of the inlet end of the second discharge pipe 112 is second only to that of the first discharge pipe 111, so the second discharge pipe 112 is used to guide the particles with medium size into the corresponding accommodating chamber 22 of the collecting component 2. Because the height of the inlet end of the second discharge pipe 112 is lower than that of the first discharge pipe 111, the particles with smaller size have been discharged from the first discharge pipe 111. Under the influence of the cyclone, the particles with medium size will be between falling directly and falling against the tank wall. However, due to the structure of the separation tank body 1, the particles with medium size will always be in contact with the tank wall, but will not contact the tank wall of the separation tank body 1 at the inlet end of the first discharge pipe 111. The internal space here is still sufficient, so the particles with medium size will continue to descend until they are in contact with the tank wall at the inlet end of the second discharge pipe 112, and enter the corresponding discharge gap 12 through the inlet end of the second discharge pipe 112, and enter the corresponding collecting component.

[0020] The height of the inlet end of the third discharge pipe 113 is the lowest. The first discharge pipe 111 and the second discharge pipe 112 have already guided the discharge of particles of corresponding particle sizes. The third discharge pipe 113 is mainly used for particles with larger particle sizes. Such particles are least affected by the cyclone and basically fall by their own gravity and directly fall into the corresponding receiving chamber 22 of the collection assembly 2. In this way, particles of different particle sizes can be collected.

[0021] In this embodiment, it also includes multiple sealing components 3, the number of the sealing components 3 matches the number of the collecting components 2, and the multiple collecting components 2 are connected to the first discharge pipe 111, the second discharge pipe 112, and the third discharge pipe 113 in sequence through the multiple sealing components 3.

[0022] The function of the sealing component 3 is mainly to ensure the sealing between the collecting component 2 and the first discharge pipe 111, the second discharge pipe 112, and the third discharge pipe 113, so as to ensure that the particles inside the separation tank body 1 can be separated and discharged normally.

[0023] Preferably, the bottom ends of the first discharge pipe 111, the second discharge pipe 112, and the third discharge pipe 113 are all provided with a recess 114, which matches the sealing assembly 3, and the multiple collecting assemblies 2 are respectively connected in the recess 114 through multiple sealing assemblies 3.

[0024] We found that when the collecting component 2 is directly connected to the first discharge pipe 111, the second discharge pipe 112, and the third discharge pipe 113 through the sealing component 3, the sealing component 3 connected to the first discharge pipe 111 has no effect, but the sealing component 3 connected to the second discharge pipe 112 may block the discharge gap 12 between the first discharge pipe 111 and the second discharge pipe 112. Similarly, the sealing component 3 connected to the third discharge pipe 113 may also affect the discharge gap 12 between the second discharge pipe 112 and the third discharge pipe 113. Therefore, in order to avoid this problem, recesses 114 are provided at the bottom ends of the first discharge pipe 111, the second discharge pipe 112, and the third discharge pipe 113. This can avoid the protrusion of the sealing component 3 and ensure smooth discharge.

[0025] Optionally, the collecting component 2 is a collecting bag 21, and the sealing component 3 is a sealing buckle 31. The collecting bag 21 is detachably connected to the first discharge pipe 111, the second discharge pipe 112, and the third discharge pipe 113 through the sealing buckle 31 to collect particles of different sizes, and is also convenient for disassembly and cleaning.

[0026] In this embodiment, the first discharge pipe 111 and the separation tank body 1 are integrally formed, the outer side surface of the top of the second discharge pipe 112 is provided with a plurality of first connecting rods 1121, the outer side surface of the top of the third discharge pipe 113 is provided with a plurality of second connecting rods 1131, the second discharge pipe 112 is connected to the first discharge pipe 111 through the plurality of first connecting rods 1121, and the third discharge pipe 113 is connected to the second discharge pipe 112 through the plurality of second connecting rods 1131.

[0027] Specifically, the second discharge pipe 112 is connected to the first discharge pipe 111 through multiple first connecting rods 1121, which can ensure the normal discharge of the discharge gap 12 between the first discharge pipe 111 and the second discharge pipe 112, while also ensuring the stability of the connection between the second discharge pipe 112 and the first discharge pipe 111. The third discharge pipe 113 is connected to the second discharge pipe 112 through multiple second connecting rods 1131, and its function is the same as that of the first connecting rod 1121, so it will not be explained in detail here. In addition, due to the existence of a whirlwind inside, particles will not accumulate on the upper surface of the first connecting rod 1121 and the second connecting rod 1131.

[0028] More preferably, the first connecting rods 1121 and the second connecting rods 1131 are four in number and arranged in a cross-shaped structure. Of course, the number of the first connecting rods 1121 and the second connecting rods 1131 can be greater, but it is necessary to ensure that the normal conduction of the discharge gap 12 is not affected. This embodiment selects four rods based on the premise of economy, stability, and smooth discharge.

[0029] In this embodiment, the separation tank body 1 includes a tank body 13, a feed pipe 14 connected to one side of the top of the tank body 13, an exhaust pipe 15 connected to the top of the tank body 13 and extending into the tank body 13, and an outlet pipe 16 connected to the top of the tank body 13 and connected to the exhaust pipe 15. The tank body 13 and the first discharge pipe 111 are integrally formed.

[0030] Driven by an external gas source, particles are carried from the feed pipe 14 into the tank body 13, and a cyclone is formed in the tank body 13. Under the action of the cyclone, particles with smaller particle sizes are located on the outermost side, particles with larger particle sizes are located on the innermost side, and particles with medium particle sizes are located between the two. Therefore, a first discharge pipe 111, a second discharge pipe 112, and a third discharge pipe 113 with different inlet end heights are provided to guide the discharge of particles of three different particle sizes. Finally, clean gas enters the exhaust pipe 15 and is discharged into the outlet pipe 16.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements or modifications without departing from the principle of the present invention. These improvements or modifications should also be regarded as within the protection scope of the present invention.
