Description

Technical Field

[0001] This invention relates to the field of silicone coating mixing, and more particularly to a mixer for producing silicone coatings. Background Technology

[0002] With the continuous development of modern industry, more and more equipment needs to operate in high-temperature environments, such as high-temperature pipelines. In order to prevent high-temperature oxidation and corrosion of equipment, high-temperature resistant coatings have emerged. Organosilicon resin varnishes can generally withstand high temperatures of 200℃ for a long time and are mainly used as insulating varnishes and high-temperature adhesives for laminating materials. With the addition of pigments and fillers, they can be formulated into high-temperature resistant paints with a heat resistance temperature of 200-1000℃. However, existing high-temperature resistant coatings on the market need to be baked at 150-200℃ for a long time to dry, which makes them inconvenient for large-area construction. Two-component mixed organosilicon coatings have more convenient construction characteristics. One component consists of organosilicon resin, fillers, pigments, additives and solvents, while the other component contains crosslinking agents and catalysts. When using, the two components are mixed in a certain proportion and coated on the product surface for a certain period of time to achieve room temperature curing.

[0003] To expedite the coating process, two-component mixed silicone coatings need to be mixed. Directly applying the mixed coating can be problematic if the amount mixed at one time is too large to be used within a short period, as this can cause the coating to harden and become unusable. For ease of use, it is necessary to continuously replenish the mixed coating. Therefore, continuous mixing is the necessary mixing method for silicone coatings. Summary of the Invention

[0004] The purpose of this invention is to solve the following problems existing in the prior art: In order to speed up the coating construction, it is necessary to mix the two-component mixed silicone coating. Directly using the mixed coating for coating, if the amount mixed at one time is large, it cannot be used in a short time, and the coating is prone to self-hardening and cannot be used. For convenient use, it is necessary to keep the mixed coating continuously replenished. Therefore, continuous mixing is the required mixing method for silicone coating.

[0005] To address the problems existing in the prior art, the present invention provides a mixer for producing organosilicon coatings, including a housing with a cylindrical cavity inside, two radially distributed feed pipes on the surface of the housing, and a discharge assembly distributed adjacent to the feed pipes in the circumferential direction.

[0006] Material plates: Two material plates are adapted to be installed inside the box, and the two material plates divide the cylindrical cavity of the box into two sealed chambers.

[0007] A positioning component is used to lock one of the material plates between the feed pipe and the discharge component, so that the sealed chamber formed by the separation of the two material plates is respectively connected to the feed pipe and the discharge component.

[0008] A drive assembly is used to drive the two material plates to rotate in the same direction, so that the two material plates are alternately locked between the feed pipe and the discharge assembly by the positioning assembly.

[0009] Preferably, the positioning component includes a positioning hole, which is opened on the inner wall of the box between the feed pipe and the discharge component. The edge of the material plate is provided with a telescopic cavity, and a positioning post is elastically slidable in the telescopic cavity by a spring. The positioning post is inserted into the positioning hole to limit the position of the material plate. The surface of the material plate is provided with an unlocking component, and the positioning post is connected to the unlocking component. The two material plates squeeze the unlocking component to retract the positioning post and release the position restriction on the material plate.

[0010] Preferably, the unlocking component includes a pressure cavity formed on one side of the material plate, a pressure handle sliding inside the pressure cavity, a steel wire fixed to the inner end of the positioning post, the steel wire passing through the pressure cavity, the inner end of the pressure handle contacting the steel wire, and a protruding handle on the side of the material plate away from the pressure cavity, the protruding handle being aligned with the outer end of the pressure handle.

[0011] Preferably, the drive assembly includes a motor, with two half gears coaxially fixed at the output end of the motor, a shaft and a bushing coaxially rotating at the center of the housing, the two material plates being respectively fixedly connected to the shaft and the bushing, and transmission gears being fixed at the ends of the shaft and the bushing, with the two half gears meshing with the two transmission gears respectively.

[0012] Preferably, the teeth of the two half-gears are symmetrically distributed, and the tooth distribution of the half-gears is greater than 90°, so that the teeth of the two half-gears have an overlapping part.

[0013] Preferably, pressure sensors are provided on both surfaces of the material plate, and the pressure sensors are connected to the motor via a controller.

[0014] Preferably, the top of the box is provided with a carrier frame, and an inclined guide plate is fixed on the surface of the carrier frame. The guide plate slides vertically into the interior of the box. The carrier frame is connected to an electric push rod, which is used to push the carrier frame to rise vertically.

[0015] Preferably, microswitches are installed inside the wall of the housing on both sides of the guide plate, and the microswitches are electrically connected to the electric push rod.

[0016] Preferably, the surface of the housing is provided with a cleaning pipe, which is radially aligned with the feed pipe, and the discharge assembly includes a discharge channel, one end of which is connected to two discharge pipes.

[0017] Compared with related technologies, the mixer for producing organosilicon coatings provided by the present invention has the following beneficial effects:

[0018] 1. The present invention forms a variable-volume sealed chamber within the cylindrical cavity of the box by two material plates. The two material plates are alternately positioned and rotated by a drive device and a positioning component, so that the volume of the two sealed chambers alternately increases and decreases. This is used for quantitative material intake and discharge, realizing continuous mixing and stirring of organosilicon mixed coatings, achieving the effect of mixing on demand, and facilitating precise control of mixing and material use rhythm.

[0019] 2. This invention achieves positioning contact between two material plates by pressing them together, and with the alternating engagement of two half gears and transmission gears, the two material plates are positioned and rotated alternately. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0029] Example 1

[0030] like Figure 1-2As shown, a mixer for making silicone coatings includes a housing 1 with a cylindrical cavity inside. Two feed pipes 11 and a cleaning pipe 12 are distributed along the same radial direction on the upper surface of the housing 1. The discharge assembly includes a discharge channel 13, which is opened at the bottom of the housing 1 and extends radially along the housing 1. The horizontal position of the discharge channel 13 is adjacent to the feed pipes 11 in the circumferential direction of the housing 1 and has at least one thickness spacing of material plates 5. Two discharge pipes 14 are connected to one end of the discharge channel 13. Valves are installed on the discharge pipes 14, feed pipes 11, and cleaning pipe 12.

[0031] like Figure 3-4 As shown, the box 1 has two material plates 5 inside. The material plates 5 are distributed radially along the box 1. The outer edge, upper edge and lower edge of the material plates 5 are in sliding contact with the cylindrical cavity, so that the two material plates 5 divide the cylindrical cavity of the box 1 into two sealed chambers.

[0032] like Figure 5-6 As shown, the positioning component 6 includes a positioning hole 63, which is opened on the inner wall of the housing 1 between the feed pipe 11 and the discharge component. A telescopic cavity 61 is opened on the edge of the material plate 5. A positioning post 62 is elastically slidably installed in the telescopic cavity 61 by means of a spring. The positioning post 62 is adapted to the positioning hole 63. The unlocking component includes a pressure cavity 64 opened on one side of the material plate 5. A pressure handle 65 is slidably installed in the pressure cavity 64. The pressure handle 65 protrudes from the surface of the material plate 5. A steel wire 67 is fixedly connected to the inner end of the positioning post 62. The other end of the steel wire 67 passes through and is fixed in the pressure cavity 64, so that the inner end of the pressure handle 65 contacts and squeezes the steel wire 67. A protruding handle 66 is provided on the side of the material plate 5 away from the pressure cavity 64. The protruding handle 66 is aligned with the outer end of the pressure handle 65.

[0033] like Figure 1 , 5 As shown, the drive assembly includes a motor 2, which is mounted on the top of the housing 1. Two half gears 21 are coaxially fixed at the output end of the motor 2. A shaft 23 and a bushing 24 are coaxially rotatably mounted at the center of the housing 1. Two material plates 5 are respectively fixedly connected to the shaft 23 and the bushing 24. Transmission gears 22 are fixedly mounted at the top of both the shaft 23 and the bushing 24. The two half gears 21 are respectively meshed with the two transmission gears 22.

[0034] The teeth of the two half gears 21 are symmetrically distributed, and the tooth distribution of the half gears 21 is greater than 180°, so that the teeth of the two half gears 21 have an overlapping part;

[0035] Two feed pipes 11 are used to transport the two components of the silicone coating. In the initial state, the positioning post 62 at the end of one material plate 5 is inserted into the positioning hole 63, positioning the material plate 5 between the feed pipe 11 and the discharge channel 13. The other material plate 5 is located on the other side of the feed pipe 11. The two material plates 5 divide the cylindrical cavity into cavity A and cavity B. At this time, cavity A is smaller and connected to the feed pipe 11, while cavity B is larger and connected to the discharge channel 13. The half gear 21 corresponding to the locked material plate 5 does not mesh with the transmission gear 22 and is in a free state. The half-gear 21 corresponding to the lower material plate 5 meshes with the transmission gear 22. When the motor 2 is turned on, the material plate 5 is driven to rotate through the meshing half-gear 21 and transmission gear 22. The locked material plate 5 remains stationary, and the cavity A gradually expands to generate negative pressure. The two components of the silicone coating are drawn into the cavity A through the feed pipe 11 and mixed. When the free material plate 5 rotates nearly one revolution and reaches the edge of the discharge channel 13, the amount of silicone coating drawn into the cavity A reaches its maximum, while the cavity B is compressed to its minimum, continuously driving the self-driving... As the material plate 5 rotates, the protruding handle 66 on the surface of the free material plate 5 presses against the pressure handle 65 on the surface of the locked material plate 5. During the retraction of the pressure handle 65 into the pressure chamber 64, it pushes the steel wire 67 to bend. The steel wire 67 pulls the positioning pin 62 out of the positioning hole 63, releasing the lock on the material plate 5. At this time, both sets of half gears 21 reach their overlapping meshing positions, jointly pushing the two material plates 5 forward until the latter material plate 5 aligns with the positioning hole 63. At this point, the half gear 21 and transmission gear 22 corresponding to that material plate 5 disengage, and the material plate... The positioning pin 62 at the end of the plate 5 is engaged in the positioning hole 63, locking the plate 5. The previous plate 5 is released and driven to rotate forward. That is, the two plates 5 are in different states. At this time, the discharge channel 13 is connected in cavity A, and the feed pipe 11 is connected in cavity B. The plate 5 is continuously driven to move and compress cavity A, so that the mixed silicone coating in cavity A is discharged from the discharge channel 13. Cavity B gradually expands to suck in the silicone coating components from the feed pipe 11. This process is repeated so that cavity A and cavity B alternately suck in and discharge the mixture.

[0036] Since the negative pressure generated on the two feed pipes 11 is the same when the cavity A or cavity B sucks up the material, it is only necessary to match the cross-sectional dimensions of the two feed pipes 11 to achieve quantitative absorption of the two components of the silicone coating.

[0037] like Figure 5-6 As shown, pressure sensors 7 are installed on both sides of the material plate 5. The pressure sensors 7 are connected to the motor 2 through the controller. The pressure sensors 7 monitor the pressure in cavity A and cavity B. When the pressure in cavity A and cavity B is abnormal, the controller controls the motor 2 to decelerate or stop rotating to ensure the safe operation of the equipment.

[0038] During normal mixing, open the valves of both feed pipes 11 and close the valve of the cleaning pipe 12. Open one discharge pipe 14 and close the other discharge pipe 14 to maintain independent feed and discharge channels. When tilting the equipment, close the valve of the feed pipe 11, open the valve of the cleaning pipe 12, close the valve of the discharge pipe 14 used to discharge the paint, and open the valve of the other discharge pipe 14 to allow clean water to enter cavity A and cavity B for cleaning the equipment. The cleaning water is discharged independently through the discharge pipe 14.

[0039] Example 2

[0040] like Figure 1 , 4 As shown, a carrier frame 3 is set at the top of the box 1, offset from the feed pipe 11 and the discharge pipe 14. A sliding rod is installed on the edge of the box 1 to guide the carrier frame 3 vertically. An electric push rod 32 is installed on the edge of the box 1. The telescopic end of the electric push rod 32 is connected to the carrier frame 3. Several inclined guide plates 31 are fixed on the bottom surface of the carrier frame 3. The bottom of the guide plate 31 is vertically slidably inserted into the cylindrical cavity. Micro switches 4 are installed on both sides of the guide plate 31 inside the wall of the box 1. The micro switches 4 are electrically connected to the electric push rod 32.

[0041] The free material plate 5 moves and touches the micro switch 4 in front of the guide plate 31, causing the electric push rod 32 to extend and pull the guide plate 31 upward. The bottom of the guide plate 31 is flush with the top surface of the cylindrical cavity. When the free material plate 5 passes the position of the guide plate 31 and touches the micro switch 4 behind the guide plate 31, the electric push rod 32 retracts and moves the guide plate 31 downward into the cylindrical cavity. The organosilicon coating in cavity A or cavity B is laterally guided through the guide plate 31, improving the mixing uniformity.
