Description

Technical Field

[0001] This utility model relates to the field of cyclone separator technology, and in particular to a multi-tube cyclone separator. Background Technology

[0002] Multi-tube cyclone separators, also known as multi-tube cyclone dust collectors, are cyclone separator groups composed of multiple small-diameter cyclone separators. However, in existing multi-tube cyclone separators, dust often remains at the dust outlet at the bottom of the multi-tube cyclone assembly during prolonged use. Over time, this can lead to scale buildup at the dust outlet, causing blockage and hindering the rapid dust removal process, thus affecting the overall performance of the multi-tube cyclone assembly. Utility Model Content

[0003] This invention proposes a multi-tube cyclone separator to solve the problem that dust often remains at the bottom of the dust outlet of existing multi-tube cyclone components, which can easily lead to scale buildup and blockage over time.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a multi-tube cyclone separator, comprising a tank, an air inlet pipe connected to one side of the tank and an exhaust pipe connected to the other side, and a multi-tube cyclone assembly installed inside the tank, a dust collection hopper connected to the bottom of the tank, and a dust discharge valve installed at the bottom of the dust collection hopper, and a dust blowing mechanism also provided on the tank.

[0005] The soot blowing mechanism includes a jet disk, a pulse air supply component that supplies air to the jet disk, and a drive component that drives the jet disk to flip and switch the air outlet direction. The jet disk is equipped with a jet nozzle corresponding to the multi-tube cyclone assembly.

[0006] Preferably, the pulse air delivery component includes a second bracket installed on one side of the tank, an air bag installed on the second bracket, and an air delivery pipe connected to the outlet end of the air bag. A pulse solenoid valve is installed on the air delivery pipe, and a hose is connected between the air delivery pipe and the jet disc.

[0007] Preferably, the drive component includes a first bracket mounted on the side of the tank away from the second bracket, on which a motor and a cam divider are mounted. Both ends of the jet disc are connected to the inner wall of the tank with rotating shafts. The main shaft of the motor is connected to the input shaft of the cam divider. One end of one of the rotating shafts extends to the outside of the tank and is connected to the output shaft of the cam divider with a transmission component.

[0008] Preferably, the transmission component includes a secondary gear mounted on the end of the rotating shaft and a primary gear disposed on the output shaft of the cam divider, wherein the primary gear meshes with the secondary gear.

[0009] Preferably, a cover is also installed on the first bracket, and the cover covers the motor, cam divider, main gear and auxiliary gear.

[0010] Preferably, one side of the shield is provided with a plurality of ventilation holes that are equally spaced along its height direction.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0012] By setting up a soot blowing mechanism, after the separator is used, intermittent air jets can be sprayed at the dust outlet at the bottom of the multi-tube cyclone assembly to blow away the dust remaining at the dust outlet at the bottom of the multi-tube cyclone assembly. After the air jet stops blowing, the dust will naturally fall into the dust collection hopper. This achieves soot blowing at the dust outlet at the bottom of the multi-tube cyclone assembly, thereby avoiding dust accumulation and scaling at the dust outlet at the bottom of the multi-tube cyclone assembly, preventing blockage of the dust outlet at the bottom of the multi-tube cyclone assembly, ensuring normal dust discharge of the multi-tube cyclone assembly, and facilitating effective air filtration.

[0013] Furthermore, by utilizing the drive components, the direction of airflow from the jet nozzle can be switched, allowing it to intermittently blow air into the ash collection hopper to dislodge residual dust on the inner wall of the ash collection hopper, thereby cleaning the ash collection hopper, preventing scale buildup on the inner wall of the ash collection hopper, and ensuring the normal operation of the separator.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figures 1-4 The multi-tube cyclone separator shown includes a tank 1, an air inlet pipe 2 connected to one side of the tank 1 and an exhaust pipe 3 connected to the other side, and a multi-tube cyclone assembly 12 installed inside the tank 1. A dust collection hopper 4 is connected to the bottom of the tank 1, and a dust discharge valve 5 is installed at the bottom of the dust collection hopper 4. A dust blowing mechanism is also provided on the tank 1.

[0022] The soot blowing mechanism includes a jet disk 14, a pulse air supply component that supplies air to the jet disk 14, and a drive component that drives the jet disk 14 to flip and switch the air outlet direction. The jet disk 14 is equipped with a jet nozzle 16 corresponding to the multi-tube cyclone assembly 12.

[0023] Specifically, regarding the aforementioned pulse air delivery component, such as Figures 1-4 As shown, the pulse air delivery component includes a second bracket 8 installed on one side of the tank body 1, an air tank 9 installed on the second bracket 8, and an air delivery pipe 11 connected to the air outlet of the air tank 9. A pulse solenoid valve 10 is installed on the air delivery pipe 11, and a hose 13 is connected between the air delivery pipe 11 and the jet disc 14.

[0024] Specifically, regarding the aforementioned driver section, such as Figures 2-4 As shown, the drive component includes a first bracket 6 installed on the side of the tank 1 away from the second bracket 8. A motor 17 and a cam divider 18 are mounted on the first bracket 6. Both ends of the jet disc 14 are connected to the inner wall of the tank 1 by rotating shafts 15. The main shaft of the motor 17 is connected to the input shaft of the cam divider 18. One end of one of the rotating shafts 15 extends to the outside of the tank 1 and is connected to the output shaft of the cam divider 18 by a transmission component.

[0025] Specifically, the transmission components include a secondary gear 20 mounted on the end of the rotating shaft 15 and a primary gear 19 mounted on the output shaft of the cam divider 18, with the primary gear 19 meshing with the secondary gear 20.

[0026] As described above, during use, dust-laden gas can be introduced into tank 1 through air inlet pipe 2. The dust-laden gas then rises and is filtered and removed by multi-tube cyclone assembly 12. After dust removal, the gas is discharged from the air outlet at the top of multi-tube cyclone assembly 12 and then discharged to the outside through exhaust pipe 3. The dust is discharged from the dust outlet at the bottom of multi-tube cyclone assembly 12 and falls into ash collection hopper 4. When it is necessary to clean the dust, the ash discharge valve 5 can be opened to discharge the dust in ash collection hopper 4, thereby achieving the cleaning of ash collection hopper 4.

[0027] Furthermore, after the separator is in use, the rotating shaft 15 can be driven to rotate by the transmission action of the motor 17, the cam divider 18, the main gear 19, and the secondary gear 20. Subsequently, the rotating shaft 15 drives the jet disk 14 to rotate 90°, so that the jet nozzles 16 on the jet disk 14 face the bottom dust outlet of the multi-tube cyclone assembly 12 (e.g., Figure 3 As shown), at this time, the air supply pipe 11 and the air tank 9 can be quickly connected or closed by the pulse solenoid valve 10, so that the compressed air in the air tank 9 can be delivered into the hose 13 through the gap of the air supply pipe 11, and then sprayed intermittently by the jet nozzle 16 to the dust outlet at the bottom of the multi-tube cyclone assembly 12, so as to blow away the dust remaining in the dust outlet at the bottom of the multi-tube cyclone assembly 12. After the jet nozzle 16 stops blowing, the dust remaining in the dust outlet at the bottom of the multi-tube cyclone assembly 12 will fall naturally into the dust collection hopper 4. This achieves dust blowing at the dust outlet at the bottom of the multi-tube cyclone assembly 12, thereby avoiding dust accumulation and scaling at the dust outlet at the bottom of the multi-tube cyclone assembly 12, preventing the dust outlet at the bottom of the multi-tube cyclone assembly 12 from becoming blocked, ensuring the normal dust discharge of the multi-tube cyclone assembly 12, and thus facilitating effective air filtration.

[0028] Meanwhile, after the multi-tube cyclone assembly 12 is cleaned, it can again drive the rotating shaft 15 to rotate through the transmission action of the motor 17, the cam divider 18, the main gear 19, and the secondary gear 20, causing the jet disc 14 to rotate 90° again. At this time, the jet nozzles 16 on the jet disc 14 are directed towards the ash collection hopper 4 (e.g., Figure 4 (As shown), then the compressed air in the air tank 9 is intermittently supplied to the jet nozzle 16 through the air supply pipe 11 and the hose 13 via the pulse solenoid valve 10, so that the jet nozzle 16 intermittently blows air onto the ash collection hopper 4 to blow away the dust remaining on the inner wall of the ash collection hopper 4 and discharge it through the ash discharge valve 5, thereby achieving the cleaning of the ash collection hopper 4, thus avoiding the scaling of the inner wall of the ash collection hopper 4, which is conducive to ensuring the normal use of the separator.

[0029] It should be noted that the driving angle of the cam divider 18 in this embodiment can be 90°, so as to drive the jet disk 14 to rotate by 90°, which facilitates the rapid switching of the jet direction of the jet disk 14. Furthermore, the structure and principle of the multi-tube cyclone assembly 12 are existing technologies, and for details, please refer to the prior art (authorization announcement number: CN 110947531 B, name: multi-tube cyclone separator), which will not be elaborated here.

[0030] Furthermore, such as Figures 1-4 As shown, a cover 7 is also installed on the first bracket 6, and the cover 7 covers the motor 17, the cam divider 18, the main gear 19 and the auxiliary gear 20. Based on this, it can protect the motor 17, the cam divider 18, the main gear 19 and the auxiliary gear 20, so as to ensure the stable transmission of the power output by the motor 17.

[0031] Furthermore, such as Figures 2-4 As shown, a plurality of ventilation holes are also provided on one side of the baffle 7, which are evenly spaced along its height. Based on this, ventilation can be achieved inside the baffle 7, which facilitates heat dissipation of the motor 17.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
