A spray head is usually provided in the mixer to spray liquid, thereby achieving solid-liquid mixing. However, during production, the order of material addition is also different. For example, if the solid material dissolves in the liquid, it is usually necessary to put the material into the liquid in sequence; if the solid material does not dissolve, it is usually necessary to mix the solid first and then add the liquid; in chemical experiments, even solid materials generally need to be added one by one to avoid mutual interference.

DETAILED DESCRIPTION

[0040] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0041] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0042] like Figure 1-Figure 10 As shown, the present invention provides a feeding anti-blocking system for a double planetary vacuum mixer, comprising: an anti-blocking device arranged inside the vacuum mixer 1, and at least one feeding device located outside the vacuum mixer 1; at least one feeding pipe 2 is arranged on the vacuum mixer 1, and usually the number of feeding pipes 2 is set to be multiple, such as Figure 1 As shown, and arranged circumferentially on the vacuum mixer 1, so as to realize all-round feeding, the feeding pipe 2 extends from the outside of the vacuum mixer 1 to the inside of the vacuum mixer 1, the discharge port of the feeding device is connected with the feed port of the feeding pipe 2, or is connected with the feed port of the feeding pipe 2 through the anti-blocking device, and each feeding pipe 2 can correspond to a different feeding device, so as to realize the sequential feeding of different materials. The feeding device is usually used to feed solid materials, but it can also be used to feed liquid materials, so that there is no need to set a spray head in the vacuum mixer 1, to avoid the mixed material blocking the spray head when the solid and liquid are mixed, the anti-blocking device has multiple embodiments, each embodiment is set at a different position, and multiple embodiments can appear in combination, for example, in the first embodiment of the anti-blocking device, it can be set on the discharge port of the feeding pipe 2, and can also extend into the feeding pipe 2, the second embodiment can be set in the feeding pipe 2, and the two embodiments can appear simultaneously in a combined manner;

[0043] The feeding device is used to convey materials and provide conveying pressure for the materials, so that solid materials can enter the vacuum mixer 1 in the form of injection, increasing the diffusion area of ​​the solid materials in the vacuum mixer 1. At the same time, because the feeding device can provide conveying pressure for the materials, the feeding device can also be used to feed liquid materials, so that the liquid materials enter the vacuum mixer 1 in the form of jet, atomization, etc., to improve the mixing efficiency;

[0044] The anti-clogging device is used to disperse the materials entering the vacuum mixer 1 (for example, the aforementioned increase in the diffusion area of ​​the solid materials allows the liquid materials to enter the vacuum mixer 1 in an atomized state), and when the solid-liquid mixing is performed, the anti-clogging device can effectively prevent the materials from condensing and clogging at the outlet of the feed pipe 2.

[0045] On the basis of this feeding system, we provide a method for using a double planetary vacuum mixer, so as to realize the feeding of materials into the vacuum mixer 1, so that this feeding system can be applied to different mixing scenarios, and the steps are as follows:

[0046] S1: transport the barrel to the vacuum mixer 1 and connect it to the lifting system;

[0047] S2: The lifting system moves the barrel upward to connect with the mixing system and seal it;

[0048] S3: The feeding system feeds materials into the vacuum mixer 1, and the materials are solid or liquid;

[0049] S4: When feeding the material, the anti-blocking device evenly spreads the material into the vacuum mixer 1;

[0050] S5: After the feeding is completed, the feed pipe 2 is prevented from being blocked by the anti-blocking device, and the vacuum mixer 1 is vacuumed;

[0051] S6: After the stirring is completed, the vacuum system slowly introduces air into the barrel through the air pipe to relieve the pressure. After the pressure inside and outside the barrel is balanced, the lifting system moves down and the barrel is taken out.

[0052] The feeding device is composed of a booster box 31 with a conveying channel and a booster roller 32 arranged in the booster box 31. The booster roller 32 is located in the middle of the conveying channel. The booster roller 32 is movably connected to the booster box 31, and the end of the booster roller 32 extends to the outside of the booster box 31 and is connected to a driving device. The booster roller 32 can be a commercially available device for conveying materials, or any existing technology that can rotate under the drive device to achieve the effect of conveying materials. The driving device described in this application and the driving device mentioned later are all existing technologies. The conveying channel is a U-shaped channel, which is composed of a feed channel 33 arranged in the vertical direction, a discharge channel 34 arranged obliquely, and an arc channel 35 for connecting the feed channel 33 and the discharge channel 34. The angle a between the central axis of the discharge channel 34 and the central axis of the feed channel 33 is less than 90°. The booster roller 32 is located in the arc channel 35. The flow area of ​​the feed channel 33 is not less than the flow area of ​​the discharge channel 34, and the flow area of ​​the discharge channel 34 is greater than the flow area of ​​the arc channel 35. Figure 3 As shown, the conveying channel of the present invention adopts an "upward" conveying mode, rather than a traditional "dropping" conveying mode, so that when the liquid in the vacuum mixer 1 flows backward, it can be enclosed in the arc channel 35. Because the flow area of ​​the arc channel 35 is smaller than the discharge channel 34, the density of the material in the arc channel 35 is greater than that of the feed channel 33 and the discharge channel 34 under the extrusion of the booster roller 32, and there is basically no gap between the materials in the arc channel 35. Therefore, when the liquid flows backward or reversely permeates to the arc channel 35, it will be blocked by the dense material, and will not reversely permeate along the material to the material supply box like the "dropping" method, resulting in the material in the material supply box being damp, agglomerated or damaged.

[0053] In order to prevent the agglomerated materials from clogging the feed channel 33, an anti-piling device is provided on the inner wall of the feed channel 33. The anti-piling device is composed of a rotating tube 36 with teeth on the inner wall, a gear ring 37 circumferentially arranged on the outer wall of the rotating tube 36, and a screw 38 connected to a driving device. Figure 4 As shown, the screw 38 and the toothed ring 37 are both located in the placement groove of the inner wall of the feed channel 33, the outer wall of the rotating tube 36 is movably connected to the inner wall of the feed channel 33, and the screw 38 is meshed with the toothed ring 37. The driving device can drive the screw 38 to rotate, and then the screw 38 drives the rotating tube 36 to rotate in the feed channel 33 through the toothed ring 37. When the material agglomerates or is blocked in the feed channel 33 due to the reduced flow area of ​​the arc channel 35, the teeth on the inner wall of the rotating tube 36 can drive the blocked material to move, or break the agglomerated material, thereby achieving the effect of unblocking the feed channel 33.

[0054] Taking solid materials as an example, the materials enter the feed channel 33 through the material supply box (the material supply box and the feed channel 33 can be connected in a "dropping" manner), and then accumulate at the connection between the feed channel 33 and the arc channel 35. Under the action of the booster roller 32, the materials are accelerated through the arc channel 35 (if it is a liquid material, the reduction in the flow area will also have an accelerating effect. Therefore, when the anti-blocking device is not provided, the liquid material can be ejected from the feed pipe 2 in the form of a jet through the feeding device), and "rise" from the discharge channel 34 into the feed pipe 2 (or enter through the anti-blocking device), thereby realizing the "upward" supply of materials.

[0055] As mentioned above, under the dual effects of the arc channel 35 and the booster roller 32, the material can be accelerated to be output from the feeding device to the feed pipe 2. In order to further achieve the diffusion effect of the material, we provide a first anti-blocking device implementation method, which can increase the diffusion area of ​​the material on the basis of preventing blockage. In this embodiment, the anti-blocking device is arranged on the discharge port of the feed pipe 2 (the second one described later), and / or extends into the feed pipe 2 (the second one described later and the first one). The anti-blocking device includes a nozzle 41 provided with a through hole 42, and a dispersion head 43 arranged in the through hole 42; the central axis of the through hole 42 is normal to the central axis of the feed pipe 2, so that the material can directly impact the dispersion head 43, increasing the diffusion area and head after the impact. The through hole 42 is a rectangular hole, and the dispersion head 43 is a convex shape, consisting of a protruding end 431 extending along the axial direction of the feed pipe 2, and two dispersion ends 432 extending along the radial direction of the feed pipe 2, such as Figure 6 The end of the protruding end 431 is arc-shaped, and the connection between the protruding end 431 and the dispersing end 432 is also arc-shaped, so that the protruding end 431 is not easily damaged by the impact of the material, and the arc shape of the connection between the protruding end 431 and the dispersing end 432 can guide the material without a dead angle. At the same time, the arc design can easily be impacted by the material when the material condenses on it, thereby preventing blockage; in this embodiment, we provide two implementation methods,

[0056] First, the feed pipe 2 is used as the nozzle 41. The advantage of this embodiment is that the number of components inside the vacuum mixer 1 can be reduced. When the central control mixer 1 is produced, the structure of the feed pipe 2 is directly designed and optimized, thereby simplifying the installation process of the vacuum mixer 1.

[0057] Second, the feed pipe 2 is not used as the nozzle 41, and the nozzle 41 structure is directly set separately. The advantage of this embodiment is that the number and structure of the nozzle 41 can be adjusted and optimized at any time according to the needs of the equipment, and it is more flexible.

[0058] When the feed pipe 2 is used as the nozzle 41, the feed pipe 2 extends into the interior of the vacuum mixer 1, the feed pipe 2 located inside the vacuum mixer 1 is the nozzle 41, and the through hole 42 is located inside the vacuum mixer 1;

[0059] When the feed pipe 2 is not used as the nozzle 41, the end of the nozzle 41 is connected to the discharge port of the feed pipe 2, and the top of the nozzle 41 is provided with a feed hole 44 connected to the discharge port of the feed pipe 2, and the feed hole 44 and the feed pipe 2 are located on the same central axis, and the protruding end 431 is opposite to the feed hole 44, and the protruding end 431 is located in the through hole 42, or extends into the feed hole 44, or passes through the feed hole 44 and extends into the feed pipe 2. A pad 45 is provided between the dispersing end 432 and the through hole 42, and the position between the protruding end 431 and the feed hole 44 can be adjusted at any time by providing multiple pads 45 or replacing pads 45 of different heights, thereby manually adjusting the diffusion area and the head, and the nozzle 41, the pad 45 and the dispersing end 432 are connected by screws.

[0060] The first embodiment is mainly for low-viscosity mixed materials. When the viscosity of the mixed materials is high, even if the dispersion head 43 can reduce "wall hanging", it is still difficult to remove once it is blocked by the viscous material. Therefore, for mixed materials with high viscosity, the anti-blocking device usually uses the second embodiment. The feeding device is connected to the feed port of the feed pipe 2 through the anti-blocking device. The anti-blocking device includes a cover 46 provided with an eccentric tube 47, a screw cover assembly sealed and movably connected to the cover 46, and a screw cover assembly connected to the screw cover. The driving device connected to the cover assembly; the sealing cover 46 is arranged at the end of the feed port and is located outside the vacuum mixer 1, the eccentric tube 47 and the feed pipe 2 are not on the same central axis, the eccentric tube 47 passes through the sealing cover 46, the feeding device is connected with the feed pipe 2 through the eccentric tube 47, the rotary cover assembly is located in the feed pipe 2, and one end of the rotary cover assembly passes through the sealing cover 46 and is connected to the driving device, the driving device is used to drive the rotary cover assembly to rotate and translate along the axial direction of the feed pipe 2. The screw cap assembly is composed of a drive shaft 48 connected to a drive device, and a sealing plug 49 arranged at the end of the drive shaft 48. Under the action of the eccentric tube 47, the material will impact on one side of the sealing plug 49. The outer wall of the sealing plug 49 is sealed and movably connected to the inner wall of the feed pipe 2. One end of the drive shaft 48 is connected to the end face of the sealing plug 49, and the other end passes through the sealing cap 46 and is connected to the drive device. The drive shaft 48 and the sealing cap 46 are sealed and movably connected. The end of the sealing plug 49 connected to the drive shaft 48 is an inclined surface, such as Figure 8When the material is put in, the driving device drives the driving shaft 48 to rotate and move downward, as shown in FIG. Figures 9 and 10 As shown, until an opening is formed between one side of the sealing plug 49 and the feed pipe 2. At this time:

[0061] 1. The driving equipment can be stopped and only the opening is left for feeding;

[0062] 2. The sealing plug 49 is rotated without moving downward, thereby changing the opening direction and thus changing the feeding direction;

[0063] 3. The driving device allows the sealing plug 49 to continue to move downward until it is completely separated from the feed port 2 and then stops rotating, so that the flow area reaches the maximum and the feeding rate is increased;

[0064] 4. The driving device allows the sealing plug 49 to continue to move downward until it is completely separated from the feed port 2 and then continues to rotate, so that the flow area is maximized, and the feeding direction of the "large flow" material (the material flow on the side with a larger opening is greater than the material flow on the side with a smaller opening) can be changed through the inclined surface of the sealing plug 49;

[0065] Regardless of which of the above methods is selected, when the material enters the feed pipe 2 from the eccentric tube 47, it will impact on one side of the sealing plug 49. Because the opening area between the inclined surface and the feed pipe 2 is different, different material delivery speeds can be formed under the action of the inclined surface. After the material delivery is completed, the driving device rotates the sealing plug 49 through the driving shaft 48 and recovers it into the feed pipe 2. At this time, even if there is material condensed on the side wall of the sealing plug 49, it can be scraped off by the feed pipe 2 during the recovery process. If the bottom of the sealing plug 49 and the end of the feed pipe 2 are blocked by material condensation after the sealing plug 49 is recovered into the feed pipe 2, when the material is delivered again, the sealing plug 49 can be rotated and moved downward to make it easier for the sticky material to fall off. If the material condenses on the top of the sealing plug 49, when the material is delivered again, the material sprayed by the eccentric tube 47 can impact it, and cooperate with the rotation of the sealing plug 49 to impact all the sticky materials on the top, and there will be no dead angle.

[0066] It should be noted that, because the second embodiment is installed by the outer end of the feed pipe 2, it does not conflict with the first embodiment, and the two can be used at the same time.
