Description

Technical Field

[0001] The invention relates to the technical field of reactors, in particular to a foam sealant self-cleaning reactor. Background Art

[0002] Foam sealant is a single-component, moisture-curing, multi-purpose polyurethane foam filling elastic sealing material. Foam sealant is a special polyurethane product that is made by filling polyurethane prepolymer, foaming agent, catalyst and other components into a pressure-resistant aerosol can. During construction, the aerosol colloid is sprayed to the construction site through a matching sizing gun or manual nozzle to complete the molding, foaming, bonding and sealing processes in a short period of time.

[0003] The Chinese patent application number CN202121166792.1 discloses a reactor for the production of foam sealant, including a support hanger, a reactor body is provided inside the support hanger, and two rotating shaft supports are fixedly installed on the outer wall of the reactor body. The reactor body is rotatably connected to the support hanger through the two rotating shaft supports. The outside of the two rotating shaft supports are rotatably connected with support side plates. However, the viscosity of the raw material mixture becomes higher and higher during the production process, and the rotation resistance of the stirring plate becomes greater and greater, making it difficult to ensure the mixing efficiency of the stirring plate on the mixture. At the same time, the bubbles generated by the reaction of the mixed liquid during the stirring process will move upward, and the bubbles cannot be removed in time from the top layer of the mixed liquid, which will affect the reaction efficiency between the mixed liquids.

[0004] In addition, bubbles will be generated inside the mixed liquid during the reaction process. Due to the viscosity of the mixed liquid, some bubbles are difficult to move to the top layer and escape outward, resulting in an increasing number of bubbles in the mixed liquid, which in turn causes the void ratio in the subsequent polyurethane prepolymer to be too high, affecting the stability during subsequent use.

[0036] The stirring unit 6 includes a lifting part and a stirring part. The lifting part includes a guide groove 4044 provided at the bottom of the rotating seat 404. The top of the guide groove 4044 is provided with a first hydraulic cylinder 602. The outer side of the guide groove 4044 is provided with a limit track 4045. The stirring part includes an adjustment motor 603 provided at the telescopic end of the first hydraulic cylinder 602. A fixing rod 604 is provided on the rotating shaft of the adjustment motor 603. The end of the fixing rod 604 away from the adjustment motor 603 passes through the limit track 404. A stirring blade 601 is provided, and a guide hole 6013 is formed on the stirring blade 601. Each stirring blade 601 is provided with two rows of guide holes 6013. The two rows of guide holes 6013 are staggered. The number of rows of guide holes 6013 is equal to the number of mounting plates 505. The debubbling rods 506 on two adjacent mounting plates 505 are staggered and correspond one-to-one with the positions of the guide holes 6013. The distance between two adjacent debubbling rods 506 is equal to the diameter of the debubbling rod 506.

[0037] The stirring blade 601 is adjusted in tilt angle by adjusting the motor 603. The number of stirring blades 601 is not less than six. When the six stirring blades 601 are horizontal, a disc-shaped structure is formed. A baffle 6011 is provided at the top of the inner end of the stirring blade 601, and an expansion board 6012 is provided at the outer end of the stirring blade 601.

[0038] After the stirring blade 601 is adjusted to be horizontal by the regulating motor 603, the stirring blade 601 cooperates with the expansion plate 6012 and the baffle 6011 to form a water storage tank on the top. The water storage tank contracts upward by cooperating with the hydraulic rod 403, driving the mixed liquid in the kettle body 1 to move upward.

[0039] During use, the raw materials for preparing the polyurethane prepolymer are premixed, and the temperature in the kettle body 1 is first preheated by the heat medium circulation system in the temperature regulating mechanism 2. The mixed liquid is input into the kettle body 1 through the feed pipe, and the driving motor 401 is used to drive the driving rod 402, the hydraulic rod 403, the rotating seat 404, the defoaming unit 5 and the stirring unit 6 to rotate synchronously. In the initial state, the stirring blade 601 is adjusted to an inclined shape by the regulating motor 603. A liquid level gauge can be set in the kettle body 1 to detect the liquid level of the mixed liquid in the kettle body 1. The hydraulic rod 403 adjusts the height of the rotating seat 404 through the telescopic end so that the defoaming rod 506 is located at the top layer of the mixed liquid in the kettle body 1. At this time, the self-locking mechanism in the power motor 503 remains open, the rotating shaft of the power motor 503 is locked and cannot rotate, the power gear 504, the ring gear 502, the annular seat 501, the mounting plate 505 and the defoaming rod The positions of 506 are all kept fixed. Driven by the driving motor 401, the power motor 503, the power gear 504, the ring gear 502, the annular seat 501, the mounting plate 505, the debubble rod 506 and the support ring 507 rotate with the center point of the rotating seat 404 as the center of the circle. During this process, the debubble rod 506 continuously stirs the top layer of the mixed liquid. The shearing effect of the debubble rod 506 on the top layer of the mixed liquid during the rotation of the debubble rod 506 is used to accelerate the speed of bubbles separating from the top layer of the mixed liquid. At the same time, in the process of the driving motor 401 driving the stirring blade 601 and the debubble rod 506 to rotate, the stirring blade 601 stirs and mixes the mixed liquid in the kettle body 1, and in the process of the extension and contraction of the first hydraulic cylinder 602, the upper and lower heights of the stirring blade 601 in the mixed liquid are adjusted by adjusting the motor 603 and the fixed rod 604, so that the stirring blade 601 stirs and mixes the mixed liquid in the kettle body 1 more evenly.

[0040] However, the viscosity of the mixed liquid will become higher and higher during the stirring and mixing reaction process. The higher viscosity of the mixed liquid will generate higher and higher friction on the stirring blade 601, which will cause the stirring blade 601 to have higher and higher resistance in stirring the mixed liquid, which will affect the normal operation of the stirring blade 601 and the drive motor 401. In this regard:

[0041] During use, a torque sensor is provided between the rotating shaft of the driving motor 401 and the driving rod 402. A torque threshold is preset in the torque sensor. During the stirring and mixing reaction of the mixed liquid, the viscosity of the mixed liquid gradually increases. When the torque threshold preset in the torque sensor is reached, the adjusting motor 603 drives the stirring blade 601 to adjust the inclination angle through the fixed rod 604, so that the inclination angle of the stirring blade 601 becomes flatter, thereby reducing the resistance encountered by the stirring blade 601 during the rotation in the mixed liquid.

[0042] A cleaning mechanism is provided inside the kettle body 1, and the cleaning mechanism includes a second hydraulic cylinder 701 provided on the top inner side of the kettle body 1. The telescopic end of the second hydraulic cylinder 701 is provided with an annular cleaning plate 702. As the mixed liquid in the kettle body 1 reacts with heating and stirring, it will adhere to the inner wall of the kettle body 1, and the cleaning mechanism will scrape off the residual mixed liquid on the inner wall of the kettle body 1.

[0043] In addition, during the stirring process of the mixed liquid in the kettle body 1, the second hydraulic cylinder 701 is provided with a start interval time. When the time for the second hydraulic cylinder 701 to start is reached, the second hydraulic cylinder 701 drives the annular cleaning plate 702 to move down to a position level with the top surface of the mixed liquid in the kettle body 1, and scrapes the residual mixed liquid adhering to the inner wall of the kettle body 1 back into the mixed liquid to continue to participate in the reaction.

[0044] When the mixed liquid in the kettle body 1 reaches the preset preparation time, it means that the chemical reaction of the mixed liquid in the kettle body 1 has been completed under the action of the temperature and pressure in the kettle body 1, and a polyurethane prepolymer has been formed. The polyurethane prepolymer is then discharged outward through the discharge barrel 101 and loaded into a pressure-resistant aerosol can together with other components (such as foaming agent and catalyst, etc.) to complete the production of the foam sealant.

[0045] Example 2

[0046] See also Figure 1-7 In actual use, bubbles will also be generated inside the mixed liquid. As the viscosity of the mixed liquid becomes higher and higher, the bubbles in the mixed liquid are difficult to discharge and the number of bubbles will increase, resulting in an excessively high porosity in the prepared polyurethane prepolymer, affecting the stability during use. In this regard, the following embodiment 2 is provided to solve the above problem:

[0047] During use, a bubble sensor is provided inside the kettle body 1, and the bubble sensor is used to detect whether there are bubbles in the mixed liquid. When the bubbles in the mixed liquid reach a preset density, the elimination of bubbles in the mixed liquid is started. At this time, driven by the hydraulic rod 403, the stirring blade 601 is maintained inside the mixed liquid, and the plurality of regulating motors 603 respectively drive the stirring blade 601 to flip to the horizontal level through the fixed rod 604, and then the plurality of first hydraulic cylinders 602 are synchronously contracted to drive the plurality of stirring blades 601 to move upward synchronously, so that the bottom end of the debubble rod 506 is correspondingly inserted into the guide hole 6013. At this time, the plurality of stirring blades 601, the plurality of expansion plates 6012 and the plurality of baffles 6011 form a gathering tank, in which part of the mixed liquid is gathered. As the hydraulic rod 403 contracts, the mounting plate 505, the debubble rod 506 and the stirring blade 601 are driven to move out of the top layer of the mixed liquid through the rotating seat 404, and then the first hydraulic cylinder 6 02 drives the adjusting motor 603, the fixing rod 604 and the stirring blade 601 to move downward, so that the debubble rod 506 disengages from the guide hole 6013. Under the control of the height of the stirring blade 601 by the first hydraulic cylinder 602, the bottom end of the debubble rod 506 is kept corresponding to the top layer of the mixed liquid on the stirring blade 601. At this time, the self-locking mechanism on the power motor 503 is closed, the power motor 503 is started and drives the gear ring 502 to rotate through the power gear 504, and then drives the mounting plate 505 and the debubble rod 506 to rotate through the annular seat 501, and uses the debubble rod 506 to eliminate the bubbles on the top layer of the mixed liquid on the stirring blade 601. At the same time, the mixed liquid on the top of the stirring blade 601 falls through the multiple guide holes 6013 dispersed on the multiple stirring blades 601 under the influence of natural gravity. The gap created by the bubbles is larger than the guide hole 6013. During the falling process, the bubbles in the mixed liquid are completely eliminated and then remixed with the mixed liquid as a whole.

[0048] In summary, the mixed liquid in the kettle body 1 is repeatedly moved upward by the multiple stirring blades 601, and the bubbles in the top layer of the mixed liquid on the stirring blades 601 are eliminated by the power motor 503. The mixed liquid is dispersed and falls from the multiple guide holes 6013 by relying on natural gravity, thereby improving the speed of eliminating bubbles in the mixed liquid in the kettle body 1.

[0049] Then the regulating motor 603 drives the stirring blade 601 to be tilted again through the fixed rod 604, and the stirring blade 601 is extended by the hydraulic rod 403 to re-enter the interior of the mixed liquid. At this time, the stirring blade 601 can be driven by the first hydraulic cylinder 602 to move to different heights, for example, to make the stirring blade 601 close to the bottom of the mixed liquid. At this time, the stirring blade 601 is driven by multiple regulating motors 603 to flip to the horizontal position. The multiple stirring blades 601, the multiple expansion plates 6012 and the multiple baffles 6011 once again form a gathering tank to collect the mixed liquid at the bottom of the kettle body 1. Then the first hydraulic cylinder 6 02 slowly contracts, so that the stirring blade 601 gradually moves upward and the guide hole 6013 corresponds to the debubble rod 506, and then the stirring blade 601 is moved out of the liquid surface of the mixed liquid by contracting the hydraulic rod 403, and then the guide hole 6013 is separated from the debubble rod 506 by extending the first hydraulic cylinder 602, so that the mixed liquid at the bottom of the kettle body 1 is debubbled by natural gravity and the guide hole 6013, so as to eliminate bubbles in the mixed liquid or prepolymer at different heights in the kettle body 1. When the bubble sensor in the kettle body 1 detects that the bubble density in the mixed liquid is lower than the preset value, it indicates that the elimination of bubbles in the mixed liquid is completed.

[0050] In summary, driven by the first hydraulic cylinder 602, the horizontal height of the stirring blade 601 in the mixed liquid is adjusted so that multiple stirring blades 601 collect mixed liquids at different levels, and driven by the hydraulic rod 403, the top layer of the mixed liquid is moved out for defoaming, thereby improving the overall defoaming efficiency of the mixed liquid.

[0051] In addition, after the bubbles in the polyurethane prepolymer in the kettle body 1 are eliminated, although the prepolymer on the stirring blade 601 can fall through the guide hole 6013, due to the viscosity of the mixed liquid itself, a large amount of polyurethane prepolymer residue that cannot fall through the guide hole 6013 will adhere to the stirring blade 601. If these residues are not effectively utilized, it will cause a waste of raw materials. In addition, the accumulation of these residues on the stirring blade 601 will also affect the uniformity of the next stirring of the mixed liquid, resulting in unstable or reduced quality of the produced product. In this regard, the following improvements are made:

[0052] During use, when the polyurethane prepolymer is prepared and discharged outward through the discharge barrel 101, the hydraulic rod 403 drives the rotating seat 404, the mounting plate 505, the defoaming rod 506 and the stirring blade 601 to move the polyurethane prepolymer upward. At this time, the polyurethane prepolymer on the stirring blade 601 falls through the inclined surface of the stirring blade 601, and the polyurethane prepolymer remaining on the stirring blade 601 is a residue. At this time, the stirring blade 601 is driven to flip to the horizontal by multiple adjustment motors 603, and then the first hydraulic cylinder 602 is contracted to make the upper surface of the stirring blade 601 flush with the lower surface of the defoaming rod 506. At this time, the self-locking mechanism on the power motor 503 is closed, the power motor 503 is started, and the power motor 503 drives the ring gear 502 to rotate through the power gear 504, and then drives the mounting plate 505 and the debubble rod 506 to rotate through the annular seat 501, and uses the debubble rod 506 to scrape off the polyurethane prepolymer residue on the upper surface of the stirring blade 601. In the same way as the above-mentioned debubble rod 506 scrapes off the polyurethane prepolymer residue on the upper surface of the stirring blade 601, when the first hydraulic cylinder 602 drives the stirring blade 601 to move downward, the stirring blade 601 is flipped 180° by adjusting the motor 603, and then the debubble rod 506 is contracted to make the lower surface of the stirring blade 601 flush, and the power motor 503 is started to scrape off the polyurethane prepolymer residue on the lower surface of the stirring blade 601.

[0053] To summarize, by making the top surface of the stirring blade 601 correspond to the lower surface of the debubble rod 506, and then driving the debubble rod 506 to rotate by the power motor 503, the polyurethane prepolymer residue on the upper surface of the stirring blade 601 is scraped off. In the same way, by adjusting the motor 603 to flip the stirring blade 601 180°, the debubble rod 506 scrapes off the polyurethane prepolymer on the lower surface of the stirring blade 601.

[0054] When the power motor 503 drives the mounting plate 505 and the debubble rod 506 to rotate one circle, the power motor 503 is turned off, and the stirring blade 601 is quickly driven downward by the first hydraulic cylinder 602, and then the stirring blade 601 is flipped to a nearly vertical state by adjusting the motor 603. At this time, the polyurethane prepolymer residue scraped off from the stirring blade 601 by the debubble rod 506 is located at the bottom of the debubble rod 506 and falls rapidly downward by natural gravity. At the same time, the extension of the second hydraulic cylinder 701 drives the annular cleaning plate 702 to move downward to a position corresponding to the top of the stirring blade 601 in the vertical state. At this time, the stirring blade 601 is driven by the adjusting motor 603 to rotate forward and reverse repeatedly, so that the stirring blade 601 knocks on the bottom of the annular cleaning plate 702, and the vibration generated by the stirring blade 601 during the knocking is used to accelerate the removal of the residue in the area not covered by the debubble rod 506 on the stirring blade 601.

[0055] In summary, the vertical stirring blade 601 strikes the bottom of the annular cleaning plate 702, causing the stirring blade 601 to vibrate. The vibration effect of the stirring blade 601 improves the efficiency of removing residues on the stirring blade 601.

[0056] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
