Description

Technical Field

[0001] The invention relates to the technical field of mixing, in particular to a state-adjustable disperser. Background Art

[0002] In the modern coatings industry, paint dispersers are mainly used in the production process of coating chemical products to achieve functions such as crushing, breaking up and mixing of coatings, and play a vital role in the entire coating production process.

[0003] In the process of water-based paint production, in order to improve efficiency, process more materials at the same time, and accelerate the dispersion process, a single-axis disperser with multiple dispersion discs is usually used to break up the water-based paint. In the above-mentioned disperser, since multiple dispersion discs are fixed on the rotating shaft, it is difficult to adapt to the height of the paint liquid level. When the dispersion disc is too high, the dispersion disc is in direct contact with the liquid surface, causing serious splashing of the liquid surface paint when stirred and dispersed, resulting in paint waste. When the dispersion disc is too low to the liquid level, the dispersion disc is not in the best position for dispersion, and the shear force and material circulation effects are poor, resulting in reduced dispersion efficiency and dispersion quality. Reducing the distance between the dispersion discs can concentrate energy in a smaller volume and improve energy efficiency.

[0004] To this end, according to the above requirements, a state-adjustable disperser is designed to ensure the high efficiency and uniformity of the dispersion process, thereby optimizing the dispersion effect. Summary of the invention

[0021] The present invention uses a concentration measuring instrument to descend with the floating plate to contact the liquid surface of the water-based paint, and monitors the concentration of the water-based paint after dispersion in real time, so as to determine when to stop dispersing.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1: A state-adjustable disperser, combined with Figure 1 To Attachment Figure 4 , including a support frame 101, the left part of the support frame 101 is fixedly connected to a cylinder 102, when the cylinder 102 is controlled to be turned on, so that the telescopic rod of the cylinder 102 begins to extend or shorten, the switch on the cylinder 102 can be manually controlled, the telescopic end of the cylinder 102 is fixedly connected to a sliding box 104, the right part of the sliding box 104 is splined with a distance measuring rod 103, the barrel for containing the material to be dispersed is placed directly below the distance measuring rod 103, the distance measuring rod 103 contacts the bottom wall of the barrel downward, the interior of the sliding box 104 is fixedly connected to a motor 105, and the right part of the sliding box 104 is rotatably connected to a rotating shaft 10 6. The ranging rod 103 passes through the rotating shaft 106 from top to bottom, and the rotating shaft 106 is movably connected to the ranging rod 103. The output shaft of the motor 105 is connected to the rotating shaft 106 through a pulley assembly. The rotating shaft 106 is splined with a floating frame 107 along the up and down directions. The bottom ends of the rotating shaft 106 and the floating frame 107 are fixedly connected with a stirring plate 108. The support frame 101 is slidably connected with guide rods 109 symmetrically distributed along the front and back of the support frame 101 along the up and down directions. The support frame 101 is provided with a control component for controlling the ranging rod 103 to automatically detach from the bottom wall of the barrel and automatically close the cylinder 102 and start the motor 105.

[0036] Combined with Figure 5 To Attachment Figure 6 The control component includes a fixing frame 201, which is fixedly connected to the left part of the support frame 101, the top of the ranging rod 103 contacts the fixing frame 201, the inner right side of the sliding box 104 is fixedly connected with a fixing block 202, the bottom of the fixing block 202 is rotatably connected to the rotating shaft 106, and the upper left part of the fixing block 202 is fixedly connected with a contact switch 203. The contact switch 203 is electrically connected to the cylinder 102 through the control module, and is used to control the cylinder 102 to automatically close, so that the telescopic rod of the cylinder 102 stops extending or shortening, and the contact switch 203 The fixed block 202 is electrically connected to the motor 105 through the control module, and a buckle 204 is slidably connected to the ranging rod 103 for locking the ranging rod 103. A spring 205 is fixedly connected between the buckle 204 and the fixed block 202, and a tension spring 206 is fixedly connected between the sliding box 104 and the ranging rod 103. An upper inclined surface 207 is provided on the side of the ranging rod 103 close to the contact switch 203, and the contact switch 203 moves to contact the upper inclined surface 207. A lower inclined surface 208 is provided on the side of the ranging rod 103 close to the buckle 204, and the buckle 204 moves to contact the lower inclined surface 208.

[0037] Initially, the top of the distance measuring rod 103 contacts the fixed frame 201, the tension spring 206 is in a stretched state, and the distance measuring rod 103 is locked by the buckle 204. When the water-based paint needs to be dispersed, first, the water-based paint to be dispersed is put into the barrel, and the barrel is placed directly below the distance measuring rod 103, and then the cylinder 102 is manually started, and the telescopic rod of the cylinder 102 drives the sliding box 104 to move downward, so that the distance measuring rod 103, the motor 105, the rotating shaft 106, the floating frame 107, the stirring plate 108, the guide rod 109, the fixed block 202, the contact switch 203, the buckle 204, the spring 205 and the tension spring 206 move downward as a whole, and the top of the distance measuring rod 103 is separated from the fixed frame 201;

[0038] When the floating frame 107 descends to contact the surface of the water-based paint, the floating frame 107 stops moving downward due to the buoyancy, so that the stirring plate 108 on the floating frame 107 stops moving downward, and the sliding box 104 drives the distance measuring rod 103, the motor 105, the rotating shaft 106 and the stirring plate 108, the guide rod 109, the fixing block 202, the contact switch 203, the buckle 204, the spring 205 and the tension spring 206 to continue to move downward as a whole;

[0039] When the ranging rod 103 descends to contact the inner bottom wall of the barrel, the ranging rod 103 stops moving, and the sliding box 104 drives the motor 105, the rotating shaft 106 and the stirring plate 108, the guide rod 109, the fixing block 202, the contact switch 203, the buckle 204, the spring 205 and the tension spring 206 to continue to move downward as a whole, so that the buckle 204 slides to the left under the squeezing effect of the ranging rod 103, and the spring 205 is compressed, so that the locking of the ranging rod 103 can be released. At this time, the tension spring 206 is reset to drive the ranging rod 103 to move downward. The rod 103 slides upward relative to the rotating shaft 106, so that the distance measuring rod 103 is separated from the inner bottom wall of the barrel. When the contact switch 203 and the distance measuring rod 103 are close to each other, the contact switch 203 contacts the upper inclined surface 207, so that the contact switch 203 controls the cylinder 102 to be closed through the control module, and controls the motor 105 to start. The output shaft of the motor 105 drives the rotating shaft 106 to rotate through the pulley assembly, thereby driving the floating frame 107 and the stirring plate 108 to rotate, and the water-based paint is stirred and dispersed.

[0040] In summary, the present invention utilizes the buoyancy of the floating frame 107 to automatically and dynamically adjust the distance between the two stirring plates 108 in real time according to the height of the liquid level, thereby ensuring that the stirring plates 108 are always in the best working position. Regardless of how the liquid level changes, efficient shear force and material circulation can be maintained, thereby obtaining a more uniform and delicate mixture, avoiding ineffective dispersion, adapting to the processing requirements of materials of different magnitudes, and improving the versatility and flexibility of the equipment.

[0041] The present invention makes the distance measuring rod 103 descend to contact with the inner bottom wall of the barrel, so that the distance measuring rod 103 automatically separates from the inner bottom wall of the barrel upward, and automatically closes the cylinder 102 and triggers the motor 105 to start, which not only realizes the automatic stop of descending and the start of stirring and dispersing, but also avoids the problem of wear caused by the distance measuring rod 103 always contacting with the inner bottom wall of the barrel during the stirring process;

[0042] After the stirring and dispersion is completed, the telescopic rod of the manually controlled air cylinder 102 drives the sliding box 104 to move upward, so that the ranging rod 103, the motor 105, the rotating shaft 106, the floating frame 107, the stirring plate 108, the guide rod 109, the fixing block 202, the contact switch 203, the buckle 204, the spring 205 and the tension spring 206 move upward as a whole, and the top of the ranging rod 103 moves up to contact with the fixing frame 201, so that the ranging rod 103 stops moving, and the sliding box 104 drives the remaining parts to move upward. The part continues to move upward, the tension spring 206 is stretched, and the buckle 204 slides to the left due to the squeezing effect of the lower inclined surface 208, and the spring 205 is compressed until the buckle 204 is separated from the lower inclined surface 208. The spring 205 is reset so that the buckle 204 locks the ranging rod 103. During the rising process of the contact switch 203 relative to the ranging rod 103, the contact switch 203 is gradually separated from the upper inclined surface 207, so that the contact switch 203 controls the motor 105 and the cylinder 102 to be closed through the control module.

[0043] Combined with Figure 7 To Attachment Fig. 9 , and also includes a limit block 301 symmetrically distributed along the floating frame 107. The limit block 301 is rotatably connected to the floating frame 107. Under the action of centrifugal force, the limit block 301 swings downward. A torsion spring 302 is fixedly connected between the limit block 301 and the floating frame 107. The outer side of the rotating shaft 106 is fixedly connected with a latch tooth 303 symmetrically distributed along the rotating shaft 106. The latch tooth 303 is set to a soft rubber material, and the limit block 301 is limited and matched with the adjacent latch tooth 303.

[0044] When the shaft 106 rotates, the floating frame 107 is easily affected by the fluctuation of the water-based paint and shakes up and down. In order to maintain the stability of the floating frame 107 and the stirring plate 108 thereon during dispersion, the specific operation is as follows: when the shaft 106 rotates, it drives the floating frame 107, the limit block 301, the torsion spring 302 and the latch tooth 303 to rotate as a whole, the limit block 301 swings due to the centrifugal force, and the torsion spring 302 deforms, so that the latch tooth 303 limits the limit block 301. When the shaft 106 stops rotating, the limit block 301 is reversely swung and reset by the torsion spring 302, thereby automatically releasing the limit.

[0045] Combined with Fig.10 , and also includes guide pieces 401 distributed along the circumference of the stirring disk 108 , and the guide pieces 401 are fixedly connected to the stirring disk 108 .

[0046] When the disperser disperses the paint, centrifugal force is generated in the surrounding area during operation, pushing the paint to move outward, causing the paint to experience strong shear force and impact, thereby forming a dispersion function, and a relatively low pressure area is formed in the central area close to the rotating shaft 106, the so-called low-pressure area or vortex center. This low-pressure area attracts the surrounding materials to flow toward the center, thereby forming a vortex. In order to avoid some paint being affected by the vortex and gathering at the rotating shaft 106, resulting in some paint not being dispersed, the specific operation is as follows:

[0047] The paint at the center of the vortex will experience lower shear force because they are close to the rotating shaft 106 and the linear speed of the stirring element is small. Therefore, the dispersion effect in these areas is poor and it is difficult to be dispersed to the required particle size or degree of dispersion. When the paint gathers in the central area of ​​the stirring disk 108 close to the rotating shaft 106, the stirring disk 108 drives the guide sheet 401 to rotate, pushing the undispersed paint in the central area to move to the outside of the stirring disk 108, and then the undispersed paint is dispersed by the stirring disk 108. In summary, through the cooperation between the stirring disk 108 and the guide sheet 401, the paint gathered in the central area of ​​the stirring disk 108 close to the rotating shaft 106 is expanded outward, the paint in the vortex area is dispersed, and the dispersion quality is improved.

[0048] Combined with Fig.11 , and also includes a multi-stage telescopic rod 501, which is fixedly connected to the bottom of the sliding box 104, and the telescopic end of the multi-stage telescopic rod 501 is fixedly connected to a floating plate 502, and the floating plate 502 is rotatably connected to the floating frame 107, and the floating plate 502 is fixedly connected to a concentration measuring instrument 503 for monitoring the concentration of the water-based paint after dispersion.

[0049] The floating plate 502 is lowered together with the floating frame 107 until it contacts the liquid surface of the water-based paint, and the concentration measuring instrument 503 is lowered together with the floating plate 502 until it contacts the liquid surface of the water-based paint, so as to monitor the concentration of the dispersed water-based paint in real time. When the sliding box 104 is lowered relative to the floating plate 502, the multi-stage telescopic rod 501 is compressed, and the floating plate 502 is raised together with the floating frame 107, and the concentration measuring instrument 503 is raised together with the floating plate 502, thereby being separated from the liquid surface of the water-based paint. Under the action of gravity, the multi-stage telescopic rod 501 is stretched and reset.
