Description

Technical Field

[0001] The present invention relates to the technical field of fans, and particularly to an energy-saving dust removal fan equipped with a torque sensor. Background Art

[0002] The working principle of a dust removal fan is mainly to inhale dust-containing gas through the action of mechanical force and gravity, and pass it through purification devices such as filters, filter bags or electrostatic precipitators to separate and reduce the dust concentration in the air, so that clean air is discharged. There are various types of dust removal fans, including pulse bag dust removal fans, cyclone dust removal fans, wet dust removal fans and electrostatic dust removal fans, etc. Different types of dust removal fans are suitable for different working conditions and dust properties. The main structural components of the fan are impeller, casing, air inlet, support, motor, pulley, coupling, silencer, transmission parts (bearings), etc.

[0003] Currently, there are already some prior arts that can perform multi-stage filtration on the air flow drawn into the fan. For example, the patent publication number is CN114278592A. Its main technical means is to transmit the air flow through the rotation of two groups of fan blades, and then the air flow enters the dust removal pipe. The air flow obtains a spiral force under the limit of the air flow thread plate. By setting a fluff layer, some larger-sized dust particles in the air flow are blocked, and the spiral centrifugal force generated by the air flow facilitates the attachment of heavier dust particles to the inner wall under the limit of the spiral ring and the thread plate. Then the air flow passes through the multi-stage dust filter plates inside to filter the dust layer by layer, so that the overall dust particle air flow is limited and filtered out. Finally, it is discharged into the equipment that needs to intake air through the air outlet pipe. After analysis, the drawback of this technical solution is that the cleaning part on the thread plate, that is, the fluff layer, has a constant contact surface and contact surface size with the air flow, and cannot adaptively adjust the contact surface size between it and the air flow according to the torque and power of the dust removal fan, that is, cannot adaptively adjust the contact degree between the cleaning part and the air flow according to the power of the dust removal fan, resulting in the power consumed by the dust removal fan during use not being proportional to the achieved dust removal effect. Based on this, the present invention provides an energy-saving dust removal fan equipped with a torque sensor with a simple and ingenious structure, which can adaptively adjust the contact degree between the cleaning part and the air flow according to the power of the dust removal fan. Summary of the Invention

[0004] The purpose of the present invention is to provide an energy-saving dust removal fan equipped with a torque sensor for the deficiencies of the prior art, so as to solve the technical problem that the contact degree between the cleaning part and the air flow cannot be adaptively adjusted according to the power of the dust removal fan.

[0005] The purpose of the present invention can be achieved by the following technical solutions: An energy-saving dust removal fan equipped with a torque sensor, comprising: An air inlet pipe, which is connected to the inlet of the filtration chamber. The outlet of the filtration chamber is connected to the inlet of the cleaning chamber, and the outlet of the cleaning chamber is connected to a threaded pipe. A plurality of filter plates are installed in the filtration chamber; A fan blade group, which is rotatably installed in the cleaning chamber and is used to extract gas to enter from the air inlet pipe and flow out through the threaded pipe. The fan blade group is driven to rotate by a driving component; and A spiral plate, which is fixed in the cleaning chamber, and a plurality of cleaning plates are installed thereon. The plurality of cleaning plates are respectively connected to a plurality of adjusting components, and the adjusting components are connected to the driving component to drive the cleaning plates to rotate.

[0006] As a further scheme of the present invention: The driving component is connected to a torque sensor.

[0007] As a further scheme of the present invention: The adjusting component includes: An assembly block, which is installed on the plate surface of the spiral plate, and a limiting block is fixed thereon. The limiting block is rotatably connected to one end of the cleaning plate. After the air flow enters the included angle between the assembly block and the cleaning plate, it passes through the cleaning plate and continues to flow; An adjusting block, which is slidably installed on the assembly block and is located within the included angle between the assembly block and the cleaning plate. The top of the adjusting block contacts the surface of the cleaning plate facing the assembly block, and a magnetic block is arranged at the bottom of the adjusting block; An electromagnetic module, which is installed on the assembly block and is magnetically repulsive to the magnetic block. The position of the electromagnetic module is lower than the lowest point of the moving path of the magnetic block, and the electromagnetic module is connected to the driving component; and A slide rail, which is slidably matched with a slider fixed on the adjusting block.

[0008] As a further scheme of the present invention: The connection between the assembly block and the plate surface of the spiral plate is detachable.

[0009] As a further scheme of the present invention: A pushing block is installed on the adjusting block for cleaning the surface of the cleaning plate.

[0010] As a further scheme of the present invention: The top of the pushing block contacts the surface of the cleaning plate facing the assembly block. The slide rail is L-shaped, and one section of it is fixed on the assembly block, and the other section is vertically erected on the surface of the assembly block facing the cleaning plate.

[0011] As a further scheme of the present invention: The pushing block is slidably installed on the adjusting block and is connected to the adjusting block through an elastic member. When the adjusting block moves to the end of the cleaning plate away from the assembly block, the pushing block slides away from the surface of the cleaning plate facing the assembly block, and the elastic member drives the pushing block to vibrate.

[0012] The beneficial effects of the present invention: (1) In the present invention, by adjusting the component to adjust the rotation of the cleaning plate to control the angle between the cleaning plate and the plate surface of the spiral plate, the blocking effect of the cleaning plate on the air flow can be controlled; when the adjusting component drives the fan blade group to rotate rapidly, the adjusting component rotates the cleaning plate to increase the angle between it and the plate surface of the spiral plate, then the contact range between the cleaning plate and the air flow increases, and when the adjusting component drives the fan blade group to rotate slowly, the adjusting component rotates the cleaning plate to reduce the angle between it and the plate surface of the spiral plate, which can avoid the problem of the air flow velocity decreasing due to the large interception range of the cleaning plate while ensuring the dust removal effect, realizing the ability to adaptively adjust the interception range of the cleaning part for impurities according to the power of the dust removal fan, and ensuring that the power consumed by the dust removal fan is proportional to the dust removal effect; (2) In the present invention, a torque sensor is used to monitor the torque and power of the dust removal fan in real time, so as to achieve precise control of the fan. When the torque sensor detects abnormal power, it can control the fan power to be adjusted to the normal state; (3) In the present invention, when the magnetism of the electromagnetic module increases and drives the adjusting block to slide along the fixed section, the adjusting block can synchronously push the cleaning plate to flip to adjust the size of the angle between the cleaning plate and the plate surface of the spiral plate. When the magnetism of the electromagnetic module continues to increase, the slider will slide past the inflection point between the fixed section and the extended section and enter the extended section and slide on it. At this time, the adjusting block can slide along the extended section. During this process, the pushing block slides on the surface of the cleaning plate and can clean this surface.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0017] Please refer to Figures 1 - 6 As shown, the present invention is an energy-saving dust removal fan equipped with a torque sensor, including: An air inlet pipe 1, which is connected to the inlet of the filtration chamber 3. The outlet of the filtration chamber 3 is connected to the inlet of the cleaning chamber 4, and the outlet of the cleaning chamber 4 is connected to the threaded pipe 2. A plurality of filter plates 7 are installed in the filtration chamber 3; A fan blade group 5, which is rotatably installed in the cleaning chamber 4 and is used to draw in gas and flow out through the threaded pipe 2 from the air inlet pipe 1. The fan blade group 5 is driven to rotate by a driving component 6; and A spiral plate 8, which is fixed in the cleaning chamber 4, and a plurality of cleaning plates 9 are installed thereon. The plurality of cleaning plates 9 are respectively connected to a plurality of adjusting components 10, and the adjusting components 10 are connected to the driving component 6 and are used to drive the cleaning plates 9 to rotate.

[0018] In one case of this embodiment, the threaded pipe 2 is connected to the equipment that needs to intake air, and the specific type of the equipment is not limited; the fan blade group 5 includes a rotating shaft and a plurality of fan blades arranged circumferentially. The rotating shaft is connected to the output end of the driving component 6. The driving component 6 can be a motor component, or a gear component or a pulley component driven by a motor, as long as it can make the rotating shaft rotate. This embodiment does not specifically limit this here.

[0019] In actual application of this embodiment, the driving component 6 drives the fan blade group 5 to rotate, so as to extract gas to enter from the air inlet pipe 1 and discharge it through the threaded pipe 2. When the air flow passes through several filter plates 7, primary filtration is carried out. The filter plates 7 intercept larger dust particles. Subsequently, the air flow flows along the plate surface of the spiral plate 8 to form a spiral air flow. During this process, the gas is filtered by several cleaning plates 9, which is secondary filtration, realizing layer-by-layer filtration of smaller sizes in the gas. The setting of the spiral plate 8 can extend the contact time between the air flow and the cleaning plates 9. While realizing hierarchical filtration, it regularizes the gas flow direction to be the same, ensuring that the gas can fully contact the cleaning plates 9 to achieve sufficient filtration. By adjusting the component 10 to adjust the rotation of the cleaning plates 9, the angle between the cleaning plates 9 and the plate surface of the spiral plate 8 can be controlled, and the blocking effect of the cleaning plates 9 on the air flow can be controlled; when the adjusting component 10 drives the fan blade group 5 to rotate rapidly, the adjusting component 10 rotates the cleaning plates 9 to increase the angle between them and the plate surface of the spiral plate 8, then the contact range between the cleaning plates 9 and the air flow increases. When the adjusting component 10 drives the fan blade group 5 to rotate slowly, the adjusting component 10 rotates the cleaning plates 9 to reduce the angle between them and the plate surface of the spiral plate 8, which can avoid the problem that the air flow velocity decreases due to the large interception range of the cleaning plates 9 while ensuring the dust removal effect, realizing that the interception range of the cleaning parts for impurities can be adaptively adjusted according to the power of the dust removal fan, ensuring that the power consumed by the dust removal fan is proportional to the dust removal effect.

[0020] As Figures 1 - 3 shown, as a preferred embodiment of the present invention, the driving component 6 is connected to a torque sensor.

[0021] In one case of this embodiment, the driving component 6, the torque sensor and other electrical components are all connected to an external controller. The electrical components and the external controller are all prior arts, and this application does not improve them. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of this application.

[0022] In actual application of this embodiment, the torque sensor monitors the torque and power of the dust removal fan in real time, so as to achieve precise control of the fan. When the torque sensor monitors abnormal power, it can control the fan power to be adjusted to the normal state.

[0023] As Figures 3 - 6 shown, as a preferred embodiment of the present invention, the adjusting component 10 includes: An assembly block 1001, which is installed on the plate surface of the spiral plate 8, and a limit block 1002 is fixed thereon. The limit block 1002 is rotatably connected to one end of the cleaning plate 9. After the air flow enters the angle between the assembly block 1001 and the cleaning plate 9, it passes through the cleaning plate 9 and continues to flow; The adjusting block 1003 is slidably mounted on the assembling block 1001 and is located within the included angle between the assembling block 1001 and the cleaning plate 9. The top of the adjusting block 1003 contacts the surface of the cleaning plate 9 facing the assembling block 1001. A magnetic block 1007 is provided at the bottom of the adjusting block 1003. The electromagnetic module 1006 is mounted on the assembling block 1001 and is magnetically repulsive to the magnetic block 1007. The position of the electromagnetic module 1006 is lower than the lowest point of the moving path of the magnetic block 1007, and the electromagnetic module 1006 is connected to the driving assembly 6; and The slide rail 1005 is slidably engaged with the slider 1004 fixed to the adjusting block 1003.

[0024] In one case of this embodiment, the electromagnetic module 1006 includes an electromagnet and a controller for controlling the magnitude of its magnetism, and the controller is connected to an external controller. The electromagnetic module 1006 is a prior art, and this application does not improve it. Therefore, it is not necessary to disclose its specific mechanical structure and circuit structure, which does not affect the integrity of this application.

[0025] It should be noted that the cleaning plate 9 and the corresponding adjusting assembly 10 are arranged in the area where the spiral air flow flows upward; the end of the adjusting block 1003 close to the cleaning plate 9 is its top, and the position of the electromagnetic module 1006 is lower than the lowest point of the moving path of the magnetic block 1007, that is, the magnetic block 1007 is located between the electromagnetic module 1006 and the cleaning plate 9. In addition, the limiting block 1002 can limit the flipping angle of the cleaning plate 9. When the limiting block 1002 is flipped to the maximum angle, it is perpendicular to the assembling block 1001.

[0026] In the actual application of this embodiment, when it is necessary to adjust the included angle between the cleaning plate 9 and the plate surface of the spiral plate 8, the magnetism of the electromagnetic module 1006 increases, and then it can push the adjusting block 1003 away from the electromagnetic module 1006, that is, the slider 1004 slides in the slide rail 1005 in the direction away from the electromagnetic module 1006, and then the adjusting block 1003 can push the cleaning plate 9 to flip upward. By controlling the magnitude of the magnetism of the electromagnetic module 1006, the sliding distance of the adjusting block 1003 can be controlled, and further the rotation angle of the cleaning plate 9 can be controlled. That is, according to the power of the dust removal fan controlled by the driving assembly 6, the included angle between the cleaning plate 9 and the plate surface of the spiral plate 8 can be adaptively adjusted.

[0027] As Figures 3 - 6 shown, as a preferred embodiment of the present invention, the connection between the assembling block 1001 and the plate surface of the spiral plate 8 is detachable.

[0028] In one case of this embodiment, the assembly block 1001 and the plate surface of the spiral plate 8 can be connected by bolts or can adopt a snap-fit assembly method, as long as the detachable and replaceable of the assembly block 1001 can be realized, which will not be elaborated here.

[0029] As Figures 3 - 6 shown, as a preferred embodiment of the present invention, a push block 11 is installed on the adjustment block 1003 for cleaning the surface of the cleaning plate 9.

[0030] In one case of this embodiment, the top of the push block 11 contacts the surface of the cleaning plate 9 facing the assembly block 1001. The slide rail 1005 is L-shaped, and one section of it is fixed on the assembly block 1001, and the other section is vertically erected on the surface of the assembly block 1001 facing the cleaning plate 9. The section of the slide rail 1005 fixed on the assembly block 1001 is the fixed section, and the other section is the protruding section, and the fixed section and the protruding section are vertically arranged.

[0031] In the actual application of this embodiment, when the magnetism of the electromagnetic module 1006 increases and drives the adjustment block 1003 to slide along the fixed section, the adjustment block 1003 can synchronously push the cleaning plate 9 to flip, so as to adjust the angle between the cleaning plate 9 and the plate surface of the spiral plate 8. When the magnetism of the electromagnetic module 1006 continues to increase, the slider 1004 will slide past the inflection point between the fixed section and the protruding section, enter the protruding section and slide on it. At this time, the adjustment block 1003 can slide along the protruding section. During this process, the push block 11 slides on the surface of the cleaning plate 9, and can clean this surface.

[0032] As Figures 3 - 6 shown, as a preferred embodiment of the present invention, the push block 11 is slidably installed on the adjustment block 1003 and is connected to the adjustment block 1003 through an elastic member 12. When the adjustment block 1003 moves to the end of the cleaning plate 9 away from the assembly block 1001, the push block 11 slides off the surface of the cleaning plate 9 facing the assembly block 1001, and the elastic member 12 drives the push block 11 to vibrate.

[0033] In one case of this embodiment, the push block 11 is made of rubber material. When the adjustment block 1003 moves in the reverse direction and resets after vibration, the push block 11 is deformed by extrusion and gradually moves to fit with the surface of the cleaning plate 9 facing the assembly block 1001. The elastic member 12 can be a spring, or can also be an elastic structure such as a rubber column or an elastic telescopic rod, and no specific limitation is made here.

[0034] It should be noted that Figure 4This is the initial state, where the elastic member 12 is in a free state; when it is necessary to adjust the flipping of the cleaning plate 9, when the magnetic force of the electromagnetic module 1006 increases and drives the adjusting block 1003 to rise, the adjusting block 1003 first slides relative to the pushing block 11 until the top of the adjusting block 1003 contacts the surface of the cleaning plate 9 facing the assembling block 1001. Subsequently, the cleaning plate 9 gradually flips. While flipping, the adjusting block 1003 slides relative to the pushing block 11 until both the adjusting block 1003 and the pushing block 11 contact the surface of the cleaning plate 9 facing the assembling block 1001. At this time, the slider 1004 slides to the inflection point between the fixed section and the extended section. Subsequently, the slider 1004 slides on the extended section, so that both the adjusting block 1003 and the pushing block 11 slide on the surface of the cleaning plate 9, and the pushing block 11 can push away the impurities attached to the surface of the cleaning plate 9; taking Figure 6 the direction shown as an example, when the adjusting block 1003 moves to the end of the cleaning plate 9 away from the assembling block 1001, the pushing block 11 slides away from the surface of the cleaning plate 9 facing the assembling block 1001. The elastic force of the restored deformation of the elastic member 12 drives the pushing block 11 to move upward relative to the adjusting block 1003 and vibrate, so that the pushed-away impurities can be shaken off. The staff only needs to clean the inner cavity of the cleaning chamber 4, realizing the rapid cleaning of a plurality of cleaning plates 9.

[0035] The working principle of the present invention: In the above embodiment of the present invention, an energy-saving dust removal fan equipped with a torque sensor is provided. The driving assembly 6 drives the fan blade group 5 to rotate to extract gas from the air inlet pipe 1 and discharge it through the threaded pipe 2. When the air flow passes through a plurality of filter plates 7, primary filtration is carried out. The filter plates 7 intercept larger dust particles. Subsequently, the air flow flows along the plate surface of the spiral plate 8 to form a spiral air flow. During this process, the gas is filtered by a plurality of cleaning plates 9, which is secondary filtration, realizing the hierarchical filtration of smaller sizes in the gas. The setting of the spiral plate 8 can extend the contact time between the air flow and the cleaning plate 9. While realizing hierarchical filtration, it regularizes the gas flow direction to be the same, ensuring that the gas can fully contact the cleaning plate 9 to achieve full filtration. By adjusting the assembly 10 to adjust the rotation of the cleaning plate 9 to control the angle between the cleaning plate 9 and the plate surface of the spiral plate 8, the blocking effect of the cleaning plate 9 on the air flow can be controlled; when the adjusting assembly 10 drives the fan blade group 5 to rotate rapidly, the adjusting assembly 10 rotates the cleaning plate 9 to increase the angle between it and the plate surface of the spiral plate 8, so that the contact range between the cleaning plate 9 and the air flow increases. When the adjusting assembly 10 drives the fan blade group 5 to rotate slowly, the adjusting assembly 10 rotates the cleaning plate 9 to reduce the angle between it and the plate surface of the spiral plate 8, which can avoid the problem that the air flow velocity decreases due to the large interception range of the cleaning plate 9 while ensuring the dust removal effect, realizing the ability to adaptively adjust the interception range of the cleaning member for impurities according to the power of the dust removal fan, ensuring that the power consumption of the dust removal fan is proportional to the dust removal effect.

[0036] The above has described in detail an embodiment of the present invention, but the content described above is only a preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention shall still fall within the scope covered by the patent of the present invention.
