[0042] The present invention provides the following embodiments.

[0043] Example 1

[0044] This invention provides a dust removal mechanism, such as... Figures 1-2 As shown, it includes:

[0045] The fixed frame 1 includes: a central frame 11 and side frame 12 extending integrally on opposite sides;

[0046] The dust collector 2 is fixedly connected to the upper end of the middle frame 11. The dust collector 2 is equipped with a positive pressure blowing assembly 5, a negative pressure suction head 4, and an atomizing humidification assembly 8. The lower end of the dust collector 2 is open. The atomizing humidification assembly 8 is connected to the liquid conveying device 3. The negative pressure suction head 4 is connected to the negative pressure power device 13 through the suction pipe 41. The positive pressure blowing assembly 5 is connected to the pressure gas generating device 14 through the air pipe. The liquid conveying device 3, the negative pressure power device 13, and the pressure gas generating device 14 are all installed on the fixed frame 1.

[0047] Casters 6 are connected to the left and right sides of the lower end of the fixed frame 1, and the material conveying device 7 is located directly below the middle frame 11. The material conveying device 7 is used to convey the material to be dusted.

[0048] Preferably, the positive pressure blowing assembly 5 includes: an air outlet shell 51, with a plurality of air outlet nozzles 52 connected to the lower end of the air outlet shell 51;

[0049] The atomizing humidification component 8 includes: a water storage shell 81, which is connected to an atomizing nozzle 82, and the water inlet of the water storage shell 81 is connected to a drain pipe.

[0050] The negative pressure power device 13 is existing technology and can be the fan room of a rice husk baling dust collection device (CN107363064A) or a negative pressure dust collection fan of a garbage receiving system (CN 208454023U).

[0051] The pressurized gas generating device 14 is prior art and may include an air compressor;

[0052] The working principle and beneficial effects of the above technical solution are as follows:

[0053] First, pressurized gas is generated by the pressurized gas generating device 14 and input into the positive pressure blowing component 5 through the air pipe. The dust on the surface of the material is blown out by the air outlet nozzle 52 of the positive pressure blowing component 5. At the same time, negative pressure is generated by the negative pressure power device 13 to achieve dust suction through the negative pressure dust suction head 4.

[0054] Furthermore, the water storage shell 81 and the atomizing nozzle 82 can generate atomized liquid, which increases the atomization and humidification function, removes static electricity from the material surface, and increases the dust removal effect.

[0055] In this invention:

[0056] 1. Positive pressure air outlet: The blown air will blow away the material surface 360° without dead angles. The positive pressure blowing force will blow away the particles adhering to the material surface, thereby improving the removal effect.

[0057] 2. Add atomizing humidification function to remove static electricity from the material surface, thereby reducing static electricity adsorption of dust and increasing dust removal efficiency.

[0058] The present invention also has the following advantages:

[0059] 1. It can remove dust attracted by static electricity;

[0060] 2. It can remove larger dust particles;

[0061] 3. It will not damage the material surface;

[0062] 4. It will not cause material deformation;

[0063] Example 2

[0064] Based on Example 1, such as Figures 1-2 As shown,

[0065] The dust collector 2 is also equipped with:

[0066] The vertical drive shaft 9 is rotatably connected to the upper inner wall of the dust collector 2. The vertical drive shaft 9 is driven to rotate by the drive device 15. The atomizing humidification component 8 is connected to the lower end of the vertical drive shaft 9.

[0067] The drive slider 10 is driven to move in the up-down direction by the rotation of the vertical drive shaft 9;

[0068] Two sets of symmetrical adjustment components are provided. The adjustment component on the left includes an inverted V-shaped frame 111. The middle part of the inverted V-shaped frame 111 is rotatably connected to the inner wall of the dust collection cylinder 2 through a pivot in the front-back direction. The upper right side of the inverted V-shaped frame 111 is slidably connected to the hinge seat 112. The upper side of the connecting frame 113 is fixedly connected to the drive slider 10. The lower end of the connecting frame 113 is connected to the hinge seat 112. The lower ends of the two inverted V-shaped frames 111 on the left and right are respectively connected to the positive pressure blowing component 5 and the negative pressure suction head 4.

[0069] Preferably, the drive slider 10 is a threaded slider, and a threaded section is provided in the middle of the vertical drive shaft 9. The drive slider 10 is threadedly connected to the threaded section, and the drive slider 10 is slidably connected to the inner wall of the dust collector 2.

[0070] The working principle and beneficial effects of the above technical solution are as follows:

[0071] 1. When dust removal is required, the vertical drive shaft 9 is driven to rotate by the drive device 15. The vertical drive shaft 9 controls the atomizing humidification component 8 to humidify the surface of the material. Then, positive and negative pressure dust removal is performed by the positive pressure blowing component 5 and the negative pressure suction head 4. The rotation of the vertical drive shaft 9 drives the drive slider 10 to move in the up and down direction. The connecting frame 113 drives the upper part of the two inverted V-shaped frames 111 to rotate, thereby changing the position of the positive pressure blowing component 5 and the negative pressure suction head 4 at the bottom of the inverted V-shaped frame 111. The blowing and suction angles of the positive pressure blowing component 5 and the negative pressure suction head 4 are adjusted by the inverted V-shaped frame 111 to achieve 360-degree dust removal without dead angles and increase the dust removal effect.

[0072] 2. Furthermore, the positions of the positive pressure blowing component 5, the negative pressure suction head 4, and the atomizing humidification component 8 can be adjusted through a driving device 15, making control convenient.

[0073] Example 3

[0074] Based on Example 1, such as Figures 1-2 As shown, it also includes a limiting device, which includes:

[0075] The horizontal rod 121 is rotatably connected to the inner walls of the lower left and right sides of the dust collector 2. The horizontal rod 121 is driven to rotate by the drive motor 122 connected to the outside of the dust collector 2. The left and right sides of the horizontal rod 121 are provided with threaded sections two with opposite directions of rotation. Two threaded sliders 124 are respectively threadedly connected to the two threaded sections two.

[0076] Two sets of symmetrical pressing components 123 are connected to two sets of threaded sliders 124 respectively.

[0077] Preferably, the left-side pressing component 123 includes:

[0078] A vertical rod 1231 is connected to a sliding threaded slider 124. A return spring 1232 is fixedly connected between the lower part of the vertical rod 1231 and the lower end of the threaded slider 124. A first arc surface 127 is provided at the upper end of the vertical rod 1231 and a second arc surface is provided at the lower end of the vertical rod 1231. The vertical rod 1231 can be a manually telescopic rod.

[0079] The fixing block 1233 is fixedly connected to the left side wall of the dust collector 2. The lower end face of the fixing block 1233 is provided with an arc-shaped protrusion 125 and a horizontal surface 126 at intervals. The first arc surface 127 slides in contact with the lower end face of the fixing block 1233.

[0080] The working principle and beneficial effects of the above technical solution are as follows:

[0081] 1. When the material reaches the dust removal position of the dust collector 2, the drive motor 122 is controlled to drive the horizontal rod 121 to rotate, so that the two threaded sliders 124 move left and right on the horizontal rod 121. At the same time, the first arc surface 127 set on the upper end of the vertical rod 1231 connected to the threaded slider 124 slides on the arc-shaped protrusion surface 125 or the horizontal surface 126. When the threaded slider 124 slides to the arc-shaped protrusion surface 125, the arc-shaped protrusion surface 125 pushes the vertical rod 1231 to move downward, so that the second arc surface presses on the surface of the material, preventing some material from flying up during the dust blowing process.

[0082] 2. When the lowest end of the arc-shaped protrusion 125 contacts the first arc surface, it is the pressing position for the material. The threaded slider 124 of the present invention can move left and right, pressing the material at the lowest end of the arc-shaped protrusion 125 at different left and right positions, thereby avoiding the pressing position being fixed and thus making it impossible to remove dust from the pressing position.

[0083] Example 4, based on any one of Examples 1-3, further includes:

[0084] The detection device is used to sample and detect the dust information of the material to be dusted at several locations on the material conveying device. The dust information includes: the maximum thickness of the dust, the maximum particle size of the dust particles, the minimum distance between dust particles, the minimum particle size of the dust particles, and the average particle size of the dust particles.

[0089] A control device and an alarm device are included. The control device is electrically connected to a detection device, a speed detection device, a density detection device, a first air pressure detection device, a second air pressure detection device, a pressure gas generating device, and an alarm device. The control device controls the operation of the pressure gas generating device and the alarm device based on the detection device, the speed detection device, the density detection device, the first air pressure detection device, and the second air pressure detection device. The control device includes:

[0090] Step 1: Calculate the target gas pressure based on the detection device, velocity detection device, and density detection device. ;

[0091] ;

[0092] The density of dust particles, The value measured by the density detection device. It is the acceleration due to gravity. Let A be the maximum particle size of the dust particles detected by the detection device, and let A be the drag coefficient of the pressurized gas in the air tube. The coefficient of friction of the surface of the material to be dusted. is the minimum distance between dust particles detected by the detection device; h is the maximum thickness of dust detected by the detection device; C is the flow coefficient of the gas in the trachea. The dust particles detected by the detection device have a particle size greater than [missing information]. The total number of dust particles by size. The average particle size of the dust particles detected by the detection device. The total number of dust particles detected by the detection device; The dynamic viscosity of dust particles; The conveying speed of the material conveying device; This is the dust particle coverage factor (value is greater than 0 and less than 1, and the value varies depending on the coverage state; the larger the coverage area of ​​the material to be dusted, the larger the value). The larger the size, the more difficult it is to remove dust. It is the natural logarithm; denoted as the minimum particle size of dust particles obtained by the detection device; e is the natural constant. Unit density; The correction factor is obtained to take into account the differences in the adhesive state and distribution state of dust particles. To achieve the air pressure required to allow dust particles to move, without considering the stickiness of the dust.

[0093] Step 2: The control device controls the pressurized gas to work, so that the gas pressure in the gas pipe is the target gas pressure to remove dust from several materials;

[0094] Step 3: After dust removal from several materials, the actual image of the dust-removed materials is detected by a camera device, and the similarity between the actual image of the dust-removed materials and a standard image of the dust-removed materials is obtained. When similarity Similarity greater than or equal to the preset standard The air pressure inside the trachea is controlled to the target air pressure of the pressurized gas to remove dust from the remaining materials.

[0095] Step 4: When similarity If the similarity is less than the preset standard, the alarm device will sound an alarm to remind the user to inspect and repair all components of the dust removal device's exhaust nozzle.

[0096] When all components of the exhaust nozzle of the dust removal device are normal and If the pressure is greater than the corresponding first preset value Q, the adjusted air pressure is calculated, and the control device controls the air pressure in the air pipe to the adjusted air pressure to remove dust from the remaining materials.

[0097] ;

[0098] The adjusted air pressure, It is an exponential function with base e; This refers to the average detection value of the second air pressure detection device during step 2. This refers to the average detection value of the first air pressure detection device during step 2.

For the initial state of the air outlet nozzle The corresponding standard value (due to partial blockage of the nozzle during use, etc.) reduce);

[0099] If the value is less than or equal to the corresponding first preset value Q, the alarm device will sound an alarm to remind the air nozzle that it is blocked.

[0100] Steps 3 and 4 can be repeated several times until the similarity between the actual image of the dust-removed material and the standard image of the dust-removed material is high. Similarity greater than or equal to the preset standard ;

[0101] The beneficial effects of the above technical solution are as follows: 1. By selecting the appropriate target air pressure of the pressurized gas based on dust information and material conveying device information, the dust removal effect is guaranteed while avoiding excessive air pressure that could lead to waste and damage to materials.

[0102] 2. After dust removal from several materials, an image of the materials after dust removal is detected using a camera device, and the similarity between the actual image of the materials after dust removal and a standard image of the materials after dust removal is obtained. ;

[0103] When the similarity is less than the preset standard similarity, the control alarm device will sound an alarm to remind the maintenance of each component of the dust removal device. When all components are normal, the adjusted air pressure is calculated, and the control device controls the air pressure in the air pipe to the adjusted air pressure of the pressurized gas to remove dust from the remaining materials. Based on the difference between the actual dust state of the material and the detected difference, the air pressure is further adjusted on the basis of the target air pressure obtained in the theoretical state to ensure the dust removal effect.
