Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sealant production equipment, and in particular to an improved sealant production and proportioning device. Background Technology
[0002] Sealing agents are a class of surface treatment chemicals. Their core concept is to form a protective or isolating coating or film to seal or improve certain properties of a surface, such as wear resistance, corrosion resistance, high temperature resistance, and water resistance. Sealing agents are water-based systems composed of organic corrosion inhibitors, surfactants, water-soluble polymers, and other materials. They have high anti-corrosion performance and strong adhesion, as well as good dispersibility, film-forming properties, and sealing ability. In the production process, various materials need to be mixed in a certain proportion through a production mixing device to obtain a stable sealing agent.
[0003] A search revealed that Chinese Patent Publication No. CN221693545U discloses an improved sealing agent production and proportioning device. The device involves placing the required sealing agent concentrate into several storage tanks, and having an operator rotate a handle to draw the concentrate into a discharge tank through a feed pipe. The required amount of concentrate varies depending on the proportion of each concentrate, and the amount discharged is controlled by rotating the handle a certain number of times. This method results in more precise preparation and avoids resource waste.
[0004] However, existing sealants use a wide variety of raw materials, and not all of them are liquids. For example, inorganic fillers (calcium carbonate, silica, and talc, etc.), pigments (titanium dioxide, iron oxide, and carbon black, etc.), and nano-sized active substances used in industrial / construction sealants are all solids. The method of feeding raw materials quantitatively from the discharge pipe by moving the pusher plate upward is only suitable for liquid raw materials. Solid materials cannot be discharged from the discharge pipe by upward extrusion, which limits the applicability of the preparation device. Therefore, an improved sealant production and proportioning device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an improved sealing agent production proportioning device, which aims to solve the problem that the existing sealing agent production quantitative proportioning device is only applicable to liquid raw materials and has limitations.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an improved sealing agent production and proportioning device, comprising a mixing tank, a discharge pipe fixedly connected to the right side surface of the mixing tank, a motor fixedly connected to the bottom surface of the mixing tank, the top output end of the motor penetrating the mixing tank, a stirring frame fixedly connected to the top output end of the motor, a matrix pipe connected to the right side of the upper surface of the mixing tank, a side pipe fixedly connected to the upper surface of the mixing tank, an electric telescopic rod fixedly connected to the center of the upper surface of the mixing tank, a circular plate fixedly connected to the top end of the electric telescopic rod, a connecting frame fixedly connected to the upper surface of the circular plate, a fixing plate fixedly connected to the end of the connecting frame away from the circular plate, an annular groove formed on the upper surface of the fixing plate, a weighing sensor fixedly connected to the bottom surface inside the annular groove, a weighing plate fixedly connected to the upper surface of the weighing sensor, and a digital display screen fixedly connected to the upper surface of the mixing tank.
[0007] As a further description of the above technical solution:
[0008] The end of the connecting frame away from the circular plate is sleeved inside the side tube, and the upper surface of the fixing plate is in contact with the inner top surface of the mixing tank.
[0009] As a further description of the above technical solution:
[0010] The weighing plate is fixedly connected to the inside of the annular groove, and the upper surface of the weighing plate and the upper surface of the fixed plate are located on the same horizontal plane.
[0011] As a further description of the above technical solution:
[0012] The weighing sensor is electrically connected to the digital display screen.
[0013] As a further description of the above technical solution:
[0014] The diameter of the weighing plate is the same as the inner diameter of the side tube, and the weighing plate is located directly below the side tube.
[0015] As a further description of the above technical solution:
[0016] The top end of the matrix tube is threaded with a sealing cap.
[0017] As a further description of the above technical solution:
[0018] A sealing plate is fixedly connected to the outside of the connecting frame, a limiting vertical tube is sleeved on the outside of the connecting frame, and a fixing frame is fixedly connected to the outside of the limiting vertical tube.
[0019] As a further description of the above technical solution:
[0020] The bottom end of the fixing frame is fixedly connected to the upper surface of the mixing tank, and the limiting vertical tube is located directly above the sealing plate.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, a closed-loop weighing system can be formed by the combination of the side tube, electric telescopic rod, circular plate, connecting frame, fixed plate, annular groove, weighing sensor, weighing plate and digital display screen, so as to realize real-time weighing of materials and out-of-tolerance warning, ensure the accurate measurement of small proportion of materials (such as solvents and additives), avoid human error or over-addition, and at the same time, the fixed plate and connecting frame can be lowered below the liquid surface after feeding, acting as an active turbulence structure, breaking the eddy current, and significantly improving the uniformity of material mixing.
[0023] 2. In this utility model, the sealing plate can block and seal the inside of the side tube when the electric telescopic rod is activated and drives the fixed plate to move down for feeding and turbulence. This prevents external dust and impurities from entering the mixing tank through the side tube and affecting the production quality of the sealant. At the same time, the combination of the limiting vertical tube and the fixed frame can constrain the movement trajectory of the connecting frame, prevent deviation from affecting the sealing accuracy, and ensure long-term operational reliability.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figures 1-3 This utility model provides an embodiment of an improved sealing agent production and proportioning device, comprising a mixing tank 1, a discharge pipe 2 fixedly connected to the right side surface of the mixing tank 1, a DN25 PTFE-lined ball valve at the end of the discharge pipe 2, a PN10 flange loose connection, and an FEP gasket; the actuator can be manual or 24V electric, with an opening signal output, the ball valve can control the opening and closing of the discharge pipe 2, a motor 3 fixedly connected to the bottom surface of the mixing tank 1, the top output end of the motor 3 penetrating the mixing tank 1, and a stirring frame 4 fixedly connected to the top output end of the motor 3; when the motor 3 starts, it can drive the stirring frame 4 to rotate, thereby mixing and stirring the materials entering the mixing tank 1, and preventing the materials from solidifying. A matrix tube 5 is connected to the right side of the upper surface of the mixing tank 1. The main matrix material in the sealing agent raw material accounts for a large proportion. After weighing, it can be added into the mixing tank 1 through the matrix tube 5. A sealing cap 6 is threaded to the top of the matrix tube 5. The sealing cap 6 can seal the top of the matrix tube 5 to prevent external dust and impurities from falling into the mixing tank 1 from the matrix tube 5. A side tube 7 is fixedly connected to the upper surface of the mixing tank 1. The solvent and some auxiliary additives in the sealing agent raw material can be added into the mixing tank 1 through the side tube 7. There are several side tubes 7. Several side tubes 7 are used to add different kinds of solvents or additives to avoid solid-liquid mixing and adhesion to the inside of the side tube 7.
[0032] Reference Figures 2-4An electric telescopic rod 8 is fixedly connected to the center of the upper surface of the mixing tank 1. The electric telescopic rod 8 has a 5mm redundancy compression beyond its maximum stroke to ensure it can be tightened again during maintenance. A circular plate 9 is fixedly connected to the top of the electric telescopic rod 8. When the electric telescopic rod 8 is activated, it can drive the circular plate 9 to move linearly up and down. A connecting frame 10 is fixedly connected to the upper surface of the circular plate 9. When the circular plate 9 moves, it can drive the connecting frame 10 to move synchronously. The end of the connecting frame 10 away from the circular plate 9 is sleeved inside the side tube 7. A fixing plate 11 is fixedly connected to the end of the connecting frame 10 away from the circular plate 9. When the connecting frame 1... When the device moves, it can drive the fixed plate 11 to move synchronously. The upper surface of the fixed plate 11 is in contact with the inner top surface of the mixing tank 1. In the initial state, the fixed plate 11 can seal the bottom of the side pipe 7. An annular groove 12 is provided on the upper surface of the fixed plate 11. A weighing sensor 13 is fixedly connected to the inner bottom surface of the annular groove 12. The weighing sensor 13 is fixed to the bottom surface of the annular groove 12 by M3 screws. A 0.5mm thick elastic washer is provided between the screw and the sensor to prevent shearing force. A weighing plate 14 is fixedly connected to the upper surface of the weighing sensor 13. The weighing plate 14 and the weighing sensor 13 are connected to each other. The upper surface is rigidly bonded, and the lower surface is isolated from the bottom surface of the annular groove 12 by an elastic gasket, ensuring that it is only subjected to vertical loads. The diameter of the weighing plate 14 is the same as the inner diameter of the side tube 7. The weighing plate 14 is located directly below the side tube 7 and is fixedly connected to the inside of the annular groove 12. The upper surface of the weighing plate 14 and the upper surface of the fixed plate 11 are at the same level. When the material enters the side tube 7, it can fall entirely onto the weighing plate 14, thereby allowing the weighing sensor 13 to detect the weight of the material. A digital display screen 15 is fixedly connected to the upper surface of the mixing tank 1. The weighing sensor 13 and the digital display screen are connected together. Electrical connection between 15 and 13 allows the data obtained by the weighing sensor 13 to be displayed on the digital display screen 15. When the material weight is the same as the required amount, the digital display screen 15 displays normally. When the material weight does not match the required amount, the digital display screen 15 turns red. The weighing sensor 13 and the corresponding digital display screen 15 use an independent A / D conversion module or isolation circuit to prevent interference from multiple sensor signals. When multiple side tubes 7 are fed synchronously, a time-sharing polling sampling mechanism is set (such as scanning each channel at 50ms intervals) to ensure data accuracy. This is a simple PLC control technology in this field and will not be elaborated here.
[0033] Once all the required materials are added to the corresponding side tube 7, the electric telescopic rod 8 can be activated to move the fixing plate 11 downwards, allowing the fixing plate 11 to enter the mixing tank 1 and be positioned in the solution inside the mixing tank 1. At this time, the materials can fall into the mixing tank 1 and mix with the main matrix materials. Subsequently, when the motor 3 starts and drives the stirring frame 4 to rotate and mix the materials, the fixing plate 11 and the connecting frame 10 can turbulentize the mixed materials, break the eddy current, increase shear, and improve the uniformity of material mixing.
[0034] Reference Figures 2-3 A sealing plate 16 is fixedly connected to the outer side of the connecting frame 10. The sealing plate 16 adopts a composite structure of flexible elastomer (such as silicone or polyurethane) and rigid skeleton. The scraper edge thickness is 0.5-1.0mm and rounded (to avoid scratching the inner wall of the side tube 7), ensuring that the gap with the inner wall of the side tube 7 is ≤0.3mm, so as to efficiently scrape off the adhering material. When the connecting frame 10 moves, it can drive the sealing plate 16 to move synchronously. The size of the sealing plate 16 is the same as the internal size of the side tube 7 and is located directly above the side tube 7. A limiting vertical tube 17 is sleeved on the outer side of the connecting frame 10. The limiting vertical tube 17 is located directly above the sealing plate 16. A fixing frame 18 is fixedly connected to the outer side of the limiting vertical tube 17. A proximity switch or mechanical micro-motion sensor can be installed at the top of the limiting vertical tube 17 or at the fixing frame 18. When the sealing plate 16 touches the bottom of the side tube 7, it automatically triggers... The signal stops the telescopic rod movement. The bottom end of the fixing frame 18 is fixedly connected to the upper surface of the mixing tank 1. The limiting vertical tube 17 is fixedly connected to the upper surface of the mixing tank 1 through the fixing frame 18. At the same time, there are three fixing frames 18. The three fixing frames 18 are fixedly connected in a ring array on the outside of the limiting vertical tube 17, which can stably limit and fix the limiting vertical tube 17, so that the movement of the limiting vertical tube 17 remains stable and avoids deviation, which would affect the sealing effect of the fixing plate 11 on the bottom of the side tube 7 and affect the entry of the sealing plate 16 into the side tube 7. At the same time, as the connecting frame 10 drives the fixing plate 11 to move down into the mixing tank 1, the sealing plate 16 will follow into the side tube 7 to block and seal the inside of the side tube 7, preventing external dust and impurities from entering the mixing tank 1 through the side tube 7 and affecting the production quality of the sealing agent.
[0035] Working principle: Check the status of each component of the device, ensuring that the control valve outside the discharge pipe 2 is closed, the sealing cap 6 is closed on the top of the matrix pipe 5, the fixing plate 11 initially seals the bottom of the side pipe 7, and the sealing plate 16 is located directly above the side pipe 7. Open the sealing cap 6, add the weighed main matrix material into the mixing tank 1 through the matrix pipe 5, and close the sealing cap 6 again after adding to prevent impurities from entering. Add different types of solvents or auxiliary additives to the multiple side pipes 7 respectively. The material falls onto the weighing plate 14 at the bottom of the side pipe 7. The weighing sensor 13 detects the weight in real time and displays it on the digital display screen 15. When the weight reaches the preset value (if it does not meet the preset value, the screen will display the result). (Red warning) Stop adding materials. Then start the electric telescopic rod 8, which moves the circular plate 9, connecting frame 10 and fixing plate 11 downwards, so that the fixing plate 11 enters the matrix material in the mixing tank 1. At the same time, the sealing plate 16 enters the side tube 7 to seal the opening. As the sealing plate 16 moves downwards inside the side tube 7, it can scrape off the material adhering to the inside of the side tube 7, so that the material can enter the mixing tank 1 more completely. When the sealing plate 16 moves to the bottom of the side tube 7, the electric telescopic rod 8 stops moving. Then start the motor 3 to drive the stirring frame 4 to rotate. The fixing plate 11 and connecting frame 10 form turbulence with the stirring, which enhances the uniformity of material mixing.
[0036] After mixing is complete, turn off motor 3 and electric telescopic rod 8, open the control valve of discharge pipe 2, and discharge the mixed sealing agent through discharge pipe 2 to complete the production.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
