Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of putty mixing equipment, specifically, to a mixing equipment for processing high-temperature resistant sealing putty. Background Technology
[0002] High-temperature resistant sealant is a sealing material with fireproof and high-temperature resistance properties, commonly divided into organic and inorganic types. Organic sealants have a certain degree of toughness and elasticity after solidification and can come into contact with water; inorganic sealants are not water-resistant and can only be used in dry environments, but they also have a certain degree of high-temperature resistance. Furthermore, high-temperature refractory sealants are available in both dry powder and prepared sealant forms, and can be classified according to their material composition, such as clay-based, high-alumina, silica-based, and magnesia-based refractory sealants. The preparation method for high-temperature resistant sealant involves mixing an appropriate amount of sealant and water to achieve the desired viscosity. Generally, water should be poured into a container first, then the high-temperature resistant sealant should be gradually added and stirred evenly until the desired paste-like consistency is reached.
[0003] The existing publicly available technology, application number CN202323475870.8, discloses a clay mixer, including a motor and a stirring shaft. The top end of the stirring shaft is connected to the bottom end of the motor, and the bottom end of the stirring shaft is provided with a stirring structure for stirring clay. The motor is equipped with a housing, one side of which has a main handle, and the other side of which is detachably connected to an auxiliary handle, which is arranged opposite to the main handle. A grip ring is provided on the top of the housing. In use, it can be operated through the main handle or the grip ring. When stirring is difficult, the main handle and the auxiliary handle can be held simultaneously, so that the weight of the motor is distributed between the two hands, making the use more stable, avoiding shaking, and maintaining the stability and flexibility of the grip.
[0004] However, the above-mentioned patent still has certain drawbacks in use: although it can ensure the stability of stirring by holding it with both hands, it requires a lot of strength to hold it. Over time, this will increase the labor intensity and workload of the personnel, making them prone to fatigue, which will reduce the control effect and require them to stop and rest. This will reduce the continuity of stirring and is not conducive to better processing and use. Overall, the use effect is not ideal.
[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a mixing device for processing high-temperature resistant sealing putty, which has the advantages of easy operation, auxiliary support, and low work intensity, thereby solving the problems mentioned in the background technology.
[0007] To achieve the advantages of labor-saving operation, auxiliary support, and low work intensity, the specific technical solution adopted by this utility model is as follows:
[0008] A mixing device for processing high-temperature resistant sealant includes a fixed plate and a base. Several sets of movable legs are welded around the bottom periphery of the fixed plate. Fixed legs are slidably connected to the outer periphery of the movable legs. A base is welded to the bottom of the fixed legs. Several sets of fastening holes are formed around the surface of the base. An adjusting screw is threaded through one side of the movable leg. A clamping ring is rotatably connected to one end of the adjusting screw. Several sets of sliding rods are installed around the top center of the fixed plate. A bearing plate is slidably connected to the outer periphery of the sliding rods. Electric cylinders are symmetrically installed on both sides of the bottom of the bearing plate.
[0009] Furthermore, a motor is installed at the top center of the support plate, and the output end of the motor passes through one side of the fixed plate and is connected to the stirring shaft.
[0010] Furthermore, several sets of stirring blades are installed on the surface of the stirring shaft.
[0011] Furthermore, both the fixed leg surface and the movable leg surface are provided with several sets of positioning holes, and the positioning holes are fixed by fasteners.
[0012] Furthermore, the clamping ring has an arc-shaped structure.
[0013] Furthermore, a through hole is provided at the top center of the fixed plate for the movement of the stirring shaft.
[0014] Furthermore, a control panel is installed at the top of the fixing plate.
[0015] Furthermore, the size of the fixing plate is larger than the size of the tank.
[0016] Compared with the prior art, this utility model provides a mixing device for processing high-temperature resistant sealing putty, which has the following beneficial effects:
[0017] This utility model utilizes a base and a fixing plate. When mixing and processing high-temperature resistant sealing mortar, various raw material components can be added to the corresponding tanks. The tanks are then moved to a position below the fixing plate, with their tops fitting against it. This effectively reduces dust leakage and provides a certain degree of compression and limitation to the tanks. The fixing legs connected to the fixing plate can be fixed in designated positions by the base and fasteners through fastening holes, ensuring the stability of the entire structure. The tanks can also be clamped and fixed by side clamping rings, further enhancing stability. Furthermore, components such as the motor are mounted on the support plate and adjusted via an electric cylinder, effectively reducing the time the operator needs to hold the equipment during mixing, thus reducing labor and work intensity. This makes the equipment easier to use and offers advantages such as labor-saving operation, auxiliary support, and low work intensity. Attached Figure Description

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0026] According to an embodiment of the present invention, a mixing device for processing high-temperature resistant sealant is provided.
[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a mixing device for processing high-temperature resistant sealing putty according to an embodiment of the present invention includes a fixed plate 1 and a base 11. Several sets of movable legs 10 are welded around the bottom periphery of the fixed plate 1. Fixed legs 9 are slidably connected to the outer periphery of the movable legs 10. The base 11 is welded to the bottom of the fixed legs 9. Several sets of fastening holes 12 are formed around the surface of the base 11. An adjusting screw 14 is threaded through one side of the movable leg 10. A clamping ring 15 is rotatably connected to one end of the adjusting screw 14. Several sets of sliding rods 4 are installed around the top center of the fixed plate 1. A bearing plate 3 is slidably connected to the outer periphery of the sliding rods 4. Electric cylinders 2 are symmetrically installed on both sides of the bottom of the bearing plate 3. The fixed plate 1 is a horizontally arranged rectangular plate. Four sets of movable legs 10 (usually cylindrical or square metal rods) are evenly welded around the bottom. The movable legs 10 are perpendicular to the surface of the fixed plate 1, and their length is designed according to the adjustable range of the tank height (e.g., 200-300mm). Fixed legs 9 and base 11: Fixed legs 9 are hollow tubular structures (the structure is adapted to the movable legs 10) and are sleeved on the outside of the movable legs 10, forming a sliding pair. The bottom of the fixed legs 9 is welded to the base 11 (rectangular metal plate). The surface of the base 11 has 4-6 sets of fastening holes 12 (threaded holes or through holes), which are fixed to the ground or workbench by expansion bolts or anchor screws. Multiple sets of positioning holes 13 are evenly opened along the height direction on the surfaces of the fixed legs 9 and the movable legs 10 (e.g., one set every 50mm), which are fixed by inserting pins or bolts. The fastener passes through the corresponding positioning hole 13 to achieve height locking; Adjusting screw 14 and clamping ring 15: The adjusting screw 14 is a trapezoidal threaded screw, which horizontally passes through the threaded hole on the side wall of the moving leg 10. One end of the screw is rotatably connected to the clamping ring 15 through a thrust bearing (allowing the clamping ring 15 to rotate around the screw axis), and the other end is equipped with a handwheel or hexagonal head for easy manual adjustment; The clamping ring 15 is an arc-shaped metal plate (central angle 120°-150°), with a rubber pad on the inner surface to provide anti-slip friction when in contact with the outer wall of the tank; Structural fit relationship, height adjustment: Loosen the fastener of the positioning hole 13, slide the moving leg 10 up and down to adjust the height of the fixed plate 1, so that the bottom surface of the fixed plate 1 is in contact with the top surface of the tank (50mm increment adjustment is achieved through the spacing of the positioning holes 13), and then tighten. Fastener fixing; Tank clamping: Rotating the adjusting screw 14 pushes the clamping ring 15 towards the tank. The clamping rings 15 on both sides (usually two sets symmetrically arranged) cooperate with the bottom surface of the fixing plate 1 to form a three-point clamping of the tank from the horizontal and vertical directions (fixing plate 1 presses down, clamping ring 15 pushes to the side), ensuring the stability of the tank; Functional role, dust sealing: The size of the fixing plate 1 is larger than the tank, covering the top opening of the tank, forming a physical barrier during stirring, reducing the leakage of clay powder; Equipment fixing: The base 11 is rigidly connected to the ground through the fastening hole 12. The fixed leg 9 and the moving leg 10 form a stable support frame to prevent the equipment from shaking during stirring; Technical effect: The positioning hole 13 and the fastener cooperate to achieve quick adjustment of the height of the fixing plate 1 to adapt to tanks of different heights;The arc-shaped structure and rubber pad of the clamping ring 15 provide flexible clamping to prevent the tank from deforming under pressure, while eliminating horizontal displacement and improving the stability of the stirring process; the slide rod 4 consists of four vertically mounted optical shafts (diameter φ12-φ16mm) on the top of the fixed plate 1, arranged in a rectangular pattern. The bottom end of the optical shaft is fixed to the fixed plate 1 by bolts, and the top end extends beyond the bearing plate 3 by a certain length (e.g., 50mm), and is equipped with a limit ring to prevent the bearing plate 3 from falling off; bearing plate 3 and electric cylinder 2: the bearing plate 3 is a rectangular plate with through holes (clearance fit) at the four corners that match the slide rod 4, and the slide rod 4 enables up and down sliding guidance; the electric cylinder 2 (hydraulic cylinder or pneumatic cylinder) is symmetrically installed on both sides of the bottom of the bearing plate 3. The cylinder body is fixed to the bearing plate 3 by lugs, and the bottom end of the piston rod is hinged to the top surface of the fixed plate 1 (or connected by a spherical bearing) to ensure that the bearing plate 3 rises and falls smoothly when the electric cylinder 2 extends and retracts; structural fit relationship, lifting drive: electric cylinder 2 When the stopper rod extends or retracts, it pushes the support plate 3 to move up and down along the slide rod 4. The slide rod 4 restricts the lateral displacement of the support plate 3, ensuring the vertical movement of the stirring shaft 6. Precision control: The linear guiding action of the slide rod 4, combined with the precise stroke control of the electric cylinder 2, achieves a lifting accuracy of ±1mm for the support plate 3. Functional effects: Stirring depth adjustment: The electric cylinder 2 drives the support plate 3 to rise and fall, causing the stirring shaft 6 to move up and down, adapting to the stirring needs of mortar at different liquid levels (such as when the tank is full or half-full). Labor-saving operation: Replacing the traditional method of manually holding the stirrer, the electric cylinder 2 bears the weight of the equipment and the stirring reaction force. Operators only need to monitor the equipment operation without applying external force. The mechanical combination of the slide rod 4 and the electric cylinder 2 achieves automatic lifting and lowering of the stirring shaft 6, reducing manual intervention and labor intensity. Simultaneously, the stroke of the electric cylinder 2 can be set, causing the stirring blades 8 to reciprocate between the bottom and middle of the tank, improving the uniformity of stirring.
[0028] like Figure 1As shown, a motor 5 is installed at the top center of the support plate 3. The output end of the motor 5 passes through one side of the fixed plate 1 and is connected to the stirring shaft 6. The motor 5 (usually a geared motor 5) is fixed to the top center of the support plate 3 by bolts. The output shaft of the motor 5 passes downward through the through hole in the middle of the fixed plate 1. The edge of the through hole is provided with a wear-resistant bushing (such as a copper bushing) to reduce friction when the stirring shaft 6 rotates. Structural fit relationship, power transmission: the rotation of the motor 5 is transmitted to the stirring blades 8 through the stirring shaft 6. The rotation of the blades generates axial and radial liquid flow, which pushes the mortar to mix. Leakage prevention design: a labyrinth seal or sealing ring is used between the through hole and the stirring shaft 6 to prevent the mortar from leaking. Powder overflows from the top of the fixed plate 1; Function: High-efficiency mixing: The multi-layer layout and rotational motion of the stirring blades 8 generate strong shearing force, which quickly mixes the clay powder with the liquid, shortening the mixing time (improving efficiency compared to traditional manual mixing); Adjustable speed: The motor 5 is equipped with a frequency converter (adjustable via the control panel 7), which can adjust the speed according to the consistency of the clay (e.g., 50-200 rpm) to avoid liquid splashing caused by high-speed mixing; The stable power output of the motor 5 combined with the fluid dynamics design of the stirring blades 8 achieves uniform mixing of the clay; The lifting function of the stirring shaft 6 driven by the electric cylinder 2 allows the same equipment to be adapted to various sizes of tanks, improving versatility.
[0029] like Figure 1 As shown, several sets of stirring blades 8 are installed on the surface of the stirring shaft 6. The stirring shaft 6 is made of stainless steel, and its upper end is rigidly connected to the output shaft of the motor 5 through a coupling. Its lower end extends into the tank. Multiple sets of keyways are opened on the shaft for installing the stirring blades 8. The stirring blades 8 are paddle-type or anchor-type structures and are fixed to the stirring shaft 6 by keys and bolts. The blade spacing is set according to the height of the tank (e.g., one set every 100mm). The bottom blade is 30-50mm away from the bottom of the tank to avoid scratching.
[0030] like Figure 1 and Figure 2 As shown, several sets of positioning holes 13 are provided on the surface of the fixed leg 9 and the surface of the movable leg 10. The positioning holes 13 are fixed by fasteners. The positioning holes 13 are through holes with a diameter of φ8-φ10mm. A set of four holes is provided every 50mm along the height direction on the fixed leg 9 and the movable leg 10 (each set has four holes, evenly distributed on the four sides of the circumference or square column). The fasteners are cylindrical pins or bolts, which are inserted into the positioning holes 13 aligned with the fixed leg 9 and the movable leg 10, and locked by nuts (when bolted) or directly by interference fit (cylindrical pins). Quick positioning: By selecting positioning holes 13 of different heights, the height of the fixed plate 1 can be quickly adjusted, which is more efficient than the traditional screw lifting method. Vibration-resistant fixing: The rigid connection of the fasteners effectively prevents the fixed plate 1 from sliding down due to vibration during the stirring process, ensuring the stability of the equipment operation.
[0031] like Figure 1 and Figure 3 As shown, the clamping ring 15 has an arc-shaped structure. The components work together in the following stages: Installation: Fix the equipment to the ground using the fastening holes 12 on the base 11. Adjust the fixing plate 1 to a suitable position by sliding the moving legs 10 according to the tank height, and insert the fasteners to lock it in place. Place the tank under the fixing plate 1, and rotate the adjusting screw 14 to clamp the side wall of the tank, ensuring the tank is vertical and its top is flush with the fixing plate 1. Mixing: Start the electric cylinder 2 via the control panel 7, causing the bearing plate 3 to drive the motor 5 and stirring shaft 6 to descend until the stirring blades 8 are immersed in the clay material. Set the motor 5 speed and mixing time, and start the mixing program. The electric cylinder 2 can simultaneously move up and down according to a preset stroke (e.g., rising and falling once every 30 seconds) to enhance the mixing effect. Maintenance and cleaning: Turn off the motor 5 and electric cylinder 2, and loosen the clamping ring 1. 5. Secure the fasteners and raise the fixing plate 1 to its highest position. Remove the tank for cleaning. Regularly clean the bottom surface of the fixing plate 1 and the residue inside the clamping ring 15 to ensure a good seal for the next use. Technical benefits summary: Labor-saving design: The electric cylinder 2 and the fixed support structure replace manual handling, reducing the labor intensity of operators and allowing continuous operation without downtime. High-efficiency mixing: The combination of lifting and lowering of the stirring shaft 6 and rotation of the blades improves the uniformity of the mortar mixing and shortens the mixing time. Environmentally friendly sealing: The design of the fixing plate 1 fitting snugly against the top surface of the tank, combined with the lateral sealing of the clamping ring 15, reduces dust leakage compared to traditional open mixing, improving the working environment. Through the mechanical linkage and functional integration of the above components, this mixing equipment effectively solves the problems of high labor intensity, uneven mixing, and dust pollution in the existing technology for processing high-temperature resistant sealing mortar.
[0032] like Figure 1 As shown, a through hole is provided at the top center of the fixed plate 1 for the movement of the stirring shaft 6. The diameter of the through hole is 2-3 mm larger than the outer diameter of the stirring shaft 6, the hole wall is smoothly machined, and the bushing is made of self-lubricating material (such as polytetrafluoroethylene) to reduce the rotational resistance of the stirring shaft 6. Automated control: Operators can start the stirring and lifting functions with one button on the control panel 7 without having to contact the moving parts at close range, thus improving safety. Motion compatibility: The size design of the through hole allows the stirring shaft 6 to pass freely during the lifting process, while ensuring a sealing effect to prevent dust from entering the motor 5 area above the fixed plate 1.
[0033] like Figure 1As shown, a control panel 7 is installed at the top of the fixed plate 1. The control panel 7 is embedded in the top edge of the fixed plate 1 and integrates the start / stop button for the motor 5, the speed adjustment knob, the lifting button for the electric cylinder 2, and the emergency stop switch. It is connected to the controllers of the motor 5 and electric cylinder 2 via internal cables. Optional models of the control panel 7 include: simple button type, commonly found in customized panels for small industrial equipment, without a specific standard model, often assembled by equipment manufacturers from electrical component suppliers (such as Schneider Electric and Chint) using buttons, indicator lights, etc.; PLC integrated control panel: Siemens S7-200 SMART series, Mitsubishi FX3U series. These PLC programmable logic controllers can serve as the core controller, with external operation buttons, displays, etc., forming the control panel; Touch screen control panel: Weintek MT8071iE, Kinco. The MT4414T type of touch screen integrates display and control functions, allowing users to control the equipment through the touch interface. The control circuit in the control panel 7 is connected to the motor 5 driver. When the operator presses the start button, the signal is transmitted to the driver, which drives the motor to run according to preset parameters (such as speed and direction). Pressing the stop button cuts off the power to the motor 5. If a PLC or touch screen control panel is selected, stepless speed regulation of the motor 5 can be achieved through programming or setting parameters to adapt to the mixing needs of mortar of different consistency. The control panel 7 controls the solenoid valve or servo driver of the electric cylinder 2 to realize the extension and retraction of the electric cylinder 2. For example, pressing the up button reverses the current through the solenoid valve, and hydraulic or pneumatic pressure pushes the piston rod of the electric cylinder 2 to rise, causing the support plate and stirring shaft to move upward. The descent operation is similar. By precisely controlling the stroke and speed of the electric cylinder 2, the stirring blades 8 can be stirred at different heights in the tank to ensure uniform mixing of the mortar.
[0034] like Figure 1 As shown, the size of the fixing plate 1 is larger than the size of the tank. Dust sealing: The size of the fixing plate 1 is larger than the size of the tank, covering the top opening of the tank. It forms a physical barrier during stirring, reducing the amount of clay powder that is lifted and leaked out.
[0035] Working Principle: In actual use, personnel can add the required high-temperature resistant sealing putty powder and corresponding liquid to the tank. Then, the tank is moved directly below the fixed plate 1, and the height of the moving legs 10 is adjusted so that the stirring shaft 6 can be inserted into the tank to contact the powder, while the top of the tank contacts the surface of the fixed plate 1, achieving a top seal and preventing powder from being thrown up during stirring, thus avoiding leakage and environmental pollution. The motor 5 then drives the stirring shaft 6 to rotate, which in turn causes the stirring blades 8 to rotate, mixing the powder and liquid inside, thereby achieving the stirring and processing of the putty. Furthermore, during mixing, the operation of the electric cylinder 2 can drive the entire mixing shaft 6 to move up and down to a certain extent, allowing the mixing blades 8 to make more full contact with the raw materials at different positions, thereby improving the uniformity and thoroughness of mixing, which is more convenient for production use. Moreover, during mixing, the supporting structure can be pre-fixed to the ground through the fastening holes 12, thereby achieving structural support and fixation. At the same time, the equipment used for mixing is also fixed, which can effectively reduce the time that personnel hold the equipment, thereby reducing the labor intensity of personnel and making it easier to use with less effort. The device as a whole has the advantages of easy operation, auxiliary support, and low work intensity.
