Description

Technical Field

[0001] The present invention belongs to the technical field related to mixers, and more specifically, particularly relates to a dust collection device for a feed inlet of a mixer. Background Art

[0002] In the production of paint, dusty materials such as pigment powder, filler powder (such as calcium carbonate, talcum powder) need to be mixed. The mixer can evenly disperse these dusty materials in the liquid to ensure that the color of the paint is uniform, the covering power is good, and the stability is high. However, the mixer in the prior art has the following defects: 1. In the prior art, in order to reduce the harm caused by dust when the mixer is stirring, the enterprise installs a high-suction dust adsorption device above the mixer. However, the high-suction adsorption device will significantly increase the energy cost of the enterprise during long-term operation, and the high suction may also put forward higher requirements on the sealing performance of the mixer itself, otherwise air leakage will reduce the adsorption efficiency and indirectly increase energy consumption; 2. In the prior art, a large amount of dust will be generated at the outlet of the mixer during mixing, and the dust will run out of the adsorption radius of the adsorption device. The dust will spread outside the workshop and pollute the surrounding atmospheric environment, which will not only affect the air quality around the factory, but also may have a negative impact on the nearby ecosystem; 3. In the prior art, when the mixer is stirring, the adsorption device fails and dust accumulates wantonly in the workshop. When the dust generated by the mixer cannot be effectively adsorbed, the operator will inhale a large amount of dust, which will be deposited in the human lungs for a long time and cause pneumoconiosis.

[0033] Preferably, see Attachment Figure 1 To Attachment Figure 4 An upper mounting frame 14 is fixedly installed above the U-shaped support frame 17, and an elastic adsorption tube 20 is fixedly installed on the upper mounting frame 14. One end of the adsorption tube 20 is connected to the adsorption cover 13. The adsorption cover 13 is installed at the opening of the mixing barrel 19, and the arc edge of the adsorption cover 13 is in contact with the arc edge of the mixing barrel 19.

[0035] Specific use of the present invention: When using the present invention, first install the device in the mixing workshop, then connect the power supply of the device, and put the present invention into use after the connection is completed. When in use, it is necessary to first lift the adsorption cover 13 and the baffle plate 35 of the present invention to a position that does not affect the feeding, and then pour the mixed material into the mixing barrel 19. After pouring, the device can be started and operated.

[0036] During operation, the driving motor 23 arranged inside the mounting box 12 will rotate first, and when the driving motor 23 rotates, it will drive the first driving shaft 25 to rotate through the pulley 24, and when the first driving shaft 25 rotates, it will mesh with the gear portion of the mixing barrel 19 and drive the mixing barrel 19 to rotate horizontally, and when the mixing barrel 19 rotates, the stirring blades 30 and the central shaft 31 provided inside the mixing barrel 19 will also rotate, and the stirring blades 30 will disturb the mixed material during rotation, and the mixed material will generate a large amount of dust, and because the rotation of the mixing barrel 19 will drive the mixed material to move to the highest point, when it moves to the highest point, the dust will fall due to gravity and collide with the mixed material at the lower point, which will cause the mixed material to generate more dust, and the dust will quickly move to the opening of the mixing barrel 19, causing a large amount of dust to run out.

[0037] At the same time, the filter cartridge dust collector 21 arranged inside the installation box 12 will be started, and then the filter cartridge dust collector 21 will realize dust adsorption at the opening of the mixing barrel 19 through the adsorption tube 20 and the adsorption cover 13, and the baffle plate 35 fixedly arranged on the outer edge of the adsorption cover 13 can block the dust that quickly escapes, so that the dust returns to the bottom of the adsorption port of the adsorption cover 13, and then when the central axis 31 rotates, the cleaning component 32 arranged on the outside of the baffle plate 35 will rotate, and the cleaning component 32 will start to clean the dust on the surface of the baffle plate 35 after rotation. When the cleaning component 32 is cleaning the dust on the surface of the baffle plate 35, the side of the cleaning component 32 that is in contact with the baffle plate 35 begins to scrape the surface of the baffle plate 35, and continuous scraping will squeeze the dust, and the squeezed dust will harden, which is not conducive to adsorption by the adsorption cover 13.

[0038] Then, when the cleaning component 32 rotates, the hard dust will be subjected to the rotational force, causing it to fall into the groove body 37. After the dust falls into the groove body 37, the dust will first contact the crushing component 38 set at the opening of the groove body 37. The impact ball 57 set inside the crushing component 38 will be subjected to gravity feedback, causing the impact ball 57 to move inside the inner cavity 55 (when the cleaning component 32 rotates, the position of the impact ball 57 will also change). When the impact ball 57 is displaced, it will contact the wall of the inner cavity 55, and after contact, the outer sphere 53 will vibrate, and the vibration will be transmitted to the top of the spike ball 54 through the bottom end of the spike ball 54. When the dust falls on the spike ball 54, the vibration will shake the hard dust to loosen it. Then, the cleaning component 32 will continue to rotate, and the hard dust that has been shaken after the rotation will fall into the dust collection cavity.

[0039] When the dust enters the dust collecting chamber, the dust will contact the rotating shovel 50. At the same time, the ball 47 arranged in the spherical mounting chamber 39 will be accompanied by the kinetic force generated by the rotation of the cleaning component 32, so that the ball 47 rolls inside the spherical mounting chamber 39, and the ball 47 will contact the arc contact plate 40 provided in the first gas collecting component 44 and the second gas collecting component 48. After the contact, the ball 47 will push and squeeze the extrusion chamber 43 on the arc contact plate 40, so that the gas inside the extrusion chamber 43 enters the high-pressure chamber 46, and when the arc contact plate 40 is squeezed and pushed, the reset spring will reset the piston plate 42, and then when the ball 47 continues to move inside the spherical mounting chamber 39, it will continue to release gas into the high-pressure chamber 46. After the gas is released, the high-pressure chamber 46 is subjected to a constant pressure and will achieve jet discharge. At this time, when the hard dust falls between the rotating shovel 50 and the first partition plate 51, the dust will be blown by the jet gas to achieve a crushing effect, and the ejected gas will form a rotation effect on the rotating shovel 50.

[0040] When the rotary shovel 50 is rotating, the leakage holes 61 provided on the rotary shovel 50 will screen the hard dust, and the hard dust will be on the shovel groove 60, and the dust will fall on the surface of the first partition plate 51. Then, when the high-pressure chamber 46 sprays gas, the dust on the surface will float up, and at this time, it will be taken away by the adsorption force of the adsorption cover 13; and when the hard dust falls between the rotary shovel 50 and the first partition plate 51, the hard dust is continuously rotated and shoveled high by the rotary shovel 50, and the hard dust will be crushed after high throwing, and the crushed dust will be adsorbed away, and the hard dust will continue to be crushed by jet and high throwing in the dust collecting chamber, and when high throwing, the hard dust will be blocked by the upper crushing component 38 and cannot be discharged, while the dust can be effectively discharged.

[0041] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
