Description

Technical Field

[0001] The utility model relates to the technical field of biobased caulking agent production, and more specifically, to a mixing device for biobased caulking agent production. Background Technique

[0002] Biobased caulking agent is a caulking product that uses renewable biomass or materials obtained by biomanufacturing as raw materials; such materials usually have environmental protection characteristics such as renewable raw materials, reduced carbon emissions, and energy conservation, and some biobased materials also have good biodegradability; compared with traditional petroleum-based caulking agents, biobased caulking agents have significant advantages in terms of safety, stability, and environmental protection, and the construction is more convenient.

[0003] Currently, when mixing and stirring biobased caulking agents, many bubbles will be generated inside the biobased caulking agents. Usually, a vacuum pump is used to pump out the air in the stirring equipment, but there are still a small number of bubbles remaining in the mixed and stirred liquid during the stirring of the existing vacuum stirring equipment, thus affecting the mixing effect of the biobased caulking agent. In view of this, we propose a mixing device for biobased caulking agent production. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a mixing device for biobased caulking agent production to solve the technical problem that there are still a small number of bubbles remaining in the mixed and stirred liquid during the stirring of the current existing vacuum stirring equipment.

[0005] To solve the above technical problems, the present utility model provides the following technical solutions: A mixing device for the production of bio-based caulking agents, including a stirring tank. The top of the stirring tank is movably connected with a cover plate through a first insertion rod. The inner wall of the stirring tank is movably sleeved with an inner tank through a first bearing. The bottom of the inner tank is fixedly communicated with a protective pipe, and the protective pipe is fixedly sleeved in the upper hole of the stirring tank. The bottom of the stirring tank is fixedly connected with a support frame. A defoaming mechanism is arranged on the inner wall of the bottom of the inner tank; the defoaming mechanism includes a sleeve and a stirring unit; the sleeve is movably sleeved on the inner wall of the protective pipe. A first gear is fixedly sleeved on the bottom inner wall of the protective pipe. The bottom of the stirring tank is rotatably connected with a second gear through a first insertion rod, and the first gear is meshed with the second gear. The top of the sleeve is fixedly sleeved with a defoaming turntable. A plurality of drainage fan blades are fixedly connected to the bottom inner wall of the defoaming turntable and are distributed in an annular array. In this utility model, the mixing liquid is stirred by the auger blades, so that it is thrown upward for sufficient mixing. At the same time, through the cooperation between the gears, the drainage fan blades rotate at an increased speed. The mixing liquid flows in from the top of the defoaming turntable and is thrown around. By using the centrifugal force to throw the mixing liquid around, the mixing liquid with a little bubbles is pushed to the edge of the container, and in cooperation with a vacuum pump, the pressure of the bubbles in the mixing liquid can be further reduced, making it easier for the bubbles to break away from the mixing liquid, which is beneficial to improving the practicability of the device.

[0006] Preferably, a speed-changing ring is fixedly connected to the top inner wall of the defoaming turntable, and the speed-changing ring and two adjacent drainage fan blades form a speed-changing water flow channel. One side surface of each drainage fan blade is curved.

[0007] Preferably, the stirring unit includes a bracket, and the bracket is fixedly connected to the top of the cover plate.

[0008] Preferably, a motor is fixedly connected to the top of the bracket, and the output end of the motor is fixedly connected with a transmission rod, and one end of the transmission rod is movably sleeved inside the sleeve through a first sealing bearing.

Meanwhile, through the cooperation between gears, the drainage fan blade rotates at an increased speed. The mixed liquid flows into the defoaming turntable from the top and is scattered around. By using the centrifugal force to scatter the mixed liquid around, the mixed liquid with a little bubbles is pushed to the edge of the container. Cooperating with the vacuum pump, the pressure of the bubbles in the mixed liquid can be further reduced, making it easier for the bubbles to break away from the mixed liquid, which is beneficial to improving the practicability of the device.

[0021] Such as Figures 1 to 6As shown, the utility model relates to a mixing device for producing a bio-based seam-beautifying agent, comprising a stirring tank 1, the top of the stirring tank 1 is movably connected to a cover plate 2 through a first plug rod, the inner wall of the stirring tank 1 is movably sleeved with an inner tank 3 through a first bearing, the bottom of the inner tank 3 is fixedly connected to a protective tube 301, and the protective tube 301 is fixedly sleeved in the upper hole of the stirring tank 1, the bottom of the stirring tank 1 is fixedly connected to a support frame 4, and a defoaming mechanism 5 is arranged on the inner wall of the bottom of the inner tank 3; the defoaming mechanism 5 comprises a sleeve 501 and a stirring unit 6; the sleeve 501 is movably sleeved on the inner wall of the protective tube 301, the bottom of the inner wall of the protective tube 301 is fixedly sleeved with a first gear 502, the bottom of the stirring tank 1 is rotatably connected to a second gear 503 through a first plug rod, and the first gear 502 is rotatably connected to the second gear 503 through the first plug rod. The two gears 503 are meshed and connected, and a defoaming turntable 504 is fixedly sleeved on the top of the sleeve 501. A plurality of drainage blades 505 are fixedly connected to the inner wall of the bottom of the defoaming turntable 504, and the drainage blades 505 are distributed in a ring array. In the present invention, the mixed liquid is stirred by the auger blades 604 to be thrown upward for full mixing. At the same time, the drainage blades 505 are accelerated to rotate through the cooperation between the gears, and the mixed liquid flows into the top of the defoaming turntable 504 and is thrown around. The present invention uses centrifugal force to throw the mixed liquid around, and pushes the mixed liquid with a few bubbles to the edge of the container. In cooperation with the vacuum pump, the pressure of the bubbles in the mixed liquid can be further reduced, so that the bubbles can be more easily separated from the mixed liquid, which is beneficial to improving the practicality of the device.

[0022] In the embodiment of the present utility model, a speed-changing ring 504a is fixedly connected to the inner wall of the top of the defoaming turntable 504, and the speed-changing ring 504a and two adjacent drainage blades 505 form a speed-changing water flow channel 504b, and one side of each drainage blade 505 is a curved surface 505a. It is worth noting that by providing the speed-changing ring 504a and forming the speed-changing water flow channel 504b with two adjacent drainage blades 505, the mixed liquid flows in from the top of the defoaming turntable 504 and flows out from the side notch. In this process, the speed-changing water flow channel 504b can increase the flow rate of the mixed liquid flowing out of the defoaming turntable 504, so that the mixed liquid is sprayed all around; effect one, the particulate matter in the mixed liquid can be washed away and merged with the mixed liquid; effect two, the high-speed rotating spraying is used The method pushes the mixed liquid with a few bubbles to the edge of the container, and cooperates with the external vacuum system to further reduce the pressure of the bubbles in the liquid, making it easier for the bubbles to separate from the mixed liquid, thereby achieving the purpose of degassing the mixed liquid. Compared with the existing method, only the gas in the container needs to be completely extracted by the vacuum pump, but the bubbles in the mixed liquid cannot be extracted. The utility model can improve the degassing effect of the mixed liquid. When the transmission rod 603 rotates, the first inner gear ring 605 is meshed with the second gear 503 for transmission, thereby driving the first gear 502 to rotate, wherein the rotation speed of the first inner gear ring 605 can be increased by the second gear 503. During the rotation, the mixed liquid flows in from the top of the degassing turntable 504 and flows out from the surrounding of the degassing turntable 504. Figure 6As shown in the figure, when the mixed liquid passes through the variable-speed water flow channel 504b, the flow rate of the mixed liquid can be increased, so that it can be quickly sprayed around and collide with the inner wall of the inner tank 3. The particles in the mixed liquid contact the inner wall of the inner tank 3 through water pressure, so that they are decomposed and fully mixed with the mixed liquid. At the same time, the mixed liquid with a little bubbles is pushed to the edge of the container by means of high-speed rotary spraying, and in cooperation with the external vacuum system, the pressure of the bubbles in the liquid can be further reduced, making it easier for the bubbles to separate from the mixed liquid, so as to achieve the purpose of defoaming the mixed liquid.

[0023] In the embodiment of the present utility model, the stirring unit 6 includes a bracket 601. The bracket 601 is fixedly connected to the top of the cover plate 2. A motor 602 is fixedly connected to the top of the bracket 601. The output end of the motor 602 is fixedly connected to a transmission rod 603, and one end of the transmission rod 603 is movably sleeved inside the sleeve 501 through a first sealing bearing. A screw blade 604 is fixedly sleeved on the outer wall of the transmission rod 603. One end of the transmission rod 603 far from the motor 602 is fixedly connected to a first internal gear ring 605, and the first internal gear ring 605 is meshed with the second gear 503. By setting the screw blade 604, during the stirring process of the mixed liquid, the mixed liquid can be thrown upward and the mixing motion can be continuously carried out, so that the mixed liquid is stirred more fully, which is beneficial to improving the stirring effect of the device. Before use, first connect the input end of the external vacuum pump to the inside of the stirring tank 1, and then put the materials into the inner tank 3 according to the formula of the bio-based caulking agent. Through the external control system, the vacuum pump is made to work to completely extract the air inside the inner tank 3 and the stirring tank 1. Then, through the external circuit mechanism, the motor 602 is made to work. The motor 602 drives the transmission rod 603 to rotate and drives the screw blade 604 to rotate. During this process, the mixed liquid moves upward through the special shape of the screw blade 604 and is thrown around on the screw blade 604, and then is fully mixed with the mixed liquid at the bottom of the inner tank 3. Then, the screw blade 604 repeatedly throws the mixed liquid around, so that it can be fully mixed. Among them, when throwing, when the mixed liquid with particles contacts the mixed liquid at the bottom, through the extrusion force, part of the particles are completely crushed and fully stirred with the mixed liquid.

[0024] Working principle: This embodiment provides a mixing device for the production of bio-based joint sealants. Before use, first connect the input end of an external vacuum pump to the inside of the mixing tank 1, and then put the materials into the inner tank 3 according to the formula of the bio-based joint sealant. Through an external control system, the vacuum pump is operated to exhaust all the air inside the inner tank 3 and the mixing tank 1. Then, through an external circuit mechanism, the motor 602 is operated. The motor 602 drives the transmission rod 603 to rotate, and drives the auger blade 604 to rotate. During this process, the mixed liquid moves upward through the special shape of the auger blade 604, and is scattered around on the auger blade 604, and then is fully mixed with the mixed liquid at the bottom of the inner tank 3. Then, the mixed liquid is repeatedly scattered around by the auger blade 604 to make it fully mixed. Among them, when the mixed liquid with particles contacts the bottom mixed liquid during scattering, through the extrusion force, part of the particles are crushed completely and are fully stirred with the mixed liquid. While the transmission rod 603 is rotating, through the meshing transmission of the first internal gear ring 605 and the second gear 503, the first gear 502 is driven to rotate. Among them, the rotation speed of the first internal gear ring 605 can be increased through the second gear 503. During the rotation process, the mixed liquid flows in from the top of the defoaming turntable 504 and flows out from the periphery of the defoaming turntable 504, as Figure 6 shown. Among them, when the mixed liquid passes through the variable-speed water flow channel 504b, the flow rate of the mixed liquid can be increased, so that it is quickly sprayed around and collides with the inner wall of the inner tank 3. The particles in the mixed liquid contact the inner wall of the inner tank 3 through the water pressure, so that they are decomposed and are fully mixed with the mixed liquid. At the same time, the mixed liquid with a little bubbles is pushed to the edge of the container by means of high-speed rotating spraying, and in cooperation with the external vacuum system, the pressure of the bubbles in the liquid can be further reduced, making it easier for the bubbles to break away from the mixed liquid, so as to achieve the purpose of defoaming the mixed liquid.
