Description

Technical Field

[0001] This utility model relates to the field of static mixer technology, specifically a pipeline static mixer for phosphate chemical industry. Background Technology

[0002] A static mixer is a highly efficient mixing device with no moving parts. Through a special internal structure, fluids are cut, split, rotated, and recombined during flow, achieving uniform mixing of different media. It can handle various systems such as liquid-liquid, liquid-gas, and liquid-solid particle mixing. Compared with traditional stirring equipment, it has advantages such as compact structure, low energy consumption, stable mixing effect, and no maintenance costs. It is especially suitable for continuous production processes, effectively improving mixing efficiency and product quality consistency. In the phosphate chemical industry, static mixers are directly connected in series in the phosphate chemical pipeline system. Through its special internal structure, it can mix, react, or condition fluids such as phosphoric acid, ammonium phosphate slurry, and fluoride-containing wastewater. Its internal components are mostly made of corrosion-resistant materials such as 316L stainless steel and fluoroplastics.

[0003] In the phosphate chemical industry, common media such as ammonium phosphate slurry and dicalcium phosphate solution are prone to crystallization or contain incompletely dissolved solid particles. After prolonged use, crystals and solid particles may accumulate on the surface of the static mixer, eventually leading to blockage. Therefore, it is necessary to shut down and maintain the static mixer regularly. The static mixer is usually connected to the pipeline via flanges. During maintenance, both flanges at both ends need to be completely removed and the static mixer needs to be taken off before maintenance can be performed. The maintenance work is difficult and inefficient. The existing technology has not solved this problem. Utility Model Content

[0004] The purpose of this invention is to provide a pipeline-type static mixer for phosphate chemical industry. By setting auxiliary maintenance components, when maintaining the mixer body, only one end needs to be disassembled. Utilizing the flexibility of the connecting hose, the mixer body is rotated to separate it from the external pipeline, making it easier to remove the internal mixing components for maintenance. This can reduce the disassembly and assembly time to half of the original time, greatly improving maintenance efficiency and reducing maintenance difficulty, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A pipeline static mixer for phosphate chemical industry includes a mixer body and auxiliary maintenance components; The mixer body includes a mounting tube, two sets of first flanges are fixedly installed at both ends of the mounting tube, and a mixing component is installed inside the mounting tube; The auxiliary maintenance component includes a connecting hose, with two sets of second flanges fixedly installed at both ends of the connecting hose.

[0015] 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.

[0016] Please see Figures 1-4 This utility model provides a technical solution: A static pipeline mixer for phosphate chemical industry includes a mixer body, which includes a mounting pipe 1. Two sets of first flanges 2 are fixedly installed at both ends of the mounting pipe 1. A mixing component 3 is installed inside the mounting pipe 1. The mixing component 3 includes a first mounting ring 301 and a second mounting ring 302. Multiple sets of left-hand spiral blades 303 and right-hand spiral blades 304 are arranged between the first mounting ring 301 and the second mounting ring 302. The left-hand spiral blades 303 and right-hand spiral blades 304 are staggered and welded to each other. The first mounting ring 301 and the second mounting ring 302 are welded to the left-hand spiral blades 303 or the right-hand spiral blades 304.

[0017] The mixer body is the core carrier for mixing phosphoric acid chemical media. The core components of the mixer body are the mounting pipe 1 and the internal mixing component 3. The mounting pipe 1 is connected to the external process pipeline through the first flange 2 at the other end to ensure that media such as phosphoric acid and ammonium phosphate slurry flow stably through the equipment. The left-hand and right-hand spiral blades 304 inside are staggered, which can forcibly cut, divert and rotate the fluid without moving parts, so as to mix different media efficiently. At the same time, it meets the corrosion resistance and anti-clogging requirements of phosphoric acid chemical industry, and provides a uniform material base for subsequent reaction or conditioning.

[0018] Two sets of limiting blocks 7 are fixedly installed on both sides of the first mounting ring 301 and the second mounting ring 302. The limiting blocks 7 are slidably engaged with the limiting grooves 8. The limiting grooves 8 are opened on the inner wall of the mounting tube body 1. The mounting tube body 1 has two sets of mounting grooves 9 that are used in conjunction with the first mounting ring 301 and the second mounting ring 302.

[0019] The limiting block 7 and the limiting groove 8 are positioning structures that ensure the stable fixation of the mixing component 3 within the installation pipe body 1. The limiting block 7 is fixed on both sides of the first mounting ring 301 and the second mounting ring 302 of the mixing component 3, while the limiting groove 8 is opened on the inner wall of the installation pipe body 1, and the two slide together. The limiting block 7 and the limiting groove 8 can accurately limit the radial and circumferential displacement of the mixing component 3 within the installation pipe body 1, preventing the mixing component 3 from shaking or shifting when the medium flows, ensuring that the mixing component 3 is always in the optimal working position, and also providing guidance for the installation and disassembly of the mixing component 3, improving the ease of operation during maintenance.

[0020] The first mounting ring 301, the second mounting ring 302, and the mounting groove 9 form the assembly and positioning structure for the mixture 3 within the mounting tube 1. The first mounting ring 301 and the second mounting ring 302 serve as the frame for the mixture 3, used to fix the left-hand spiral blade 303 and the right-hand spiral blade 304. The mounting groove 9 is located inside the mounting tube 1 and matches the dimensions of the first mounting ring 301 and the second mounting ring 302. The mounting groove 9, in conjunction with the first mounting ring 301 and the second mounting ring 302, can stably embed the mixture 3 into the mounting tube 1, forming a sealed flow channel without dead corners. This prevents the medium from leaking or stagnating from the gap between the mixture 3 and the mounting tube 1, and also enhances the overall structural strength of the mixture 3 through the support of the mounting tube 1, adapting to the flow requirements of high-pressure, high-viscosity media in the phosphate chemical industry.

[0021] It also includes auxiliary maintenance components, including a connecting hose 4. Two sets of second flanges 5 are fixedly installed at both ends of the connecting hose 4. One end of the connecting hose 4 is connected to the first flange 2 at one end of the installation pipe body 1 through the second flange 5. Two sets of rotating support rods 6 are installed on both sides of the connecting hose 4. The connecting hose 4 is made of fluoroplastics such as polytetrafluoroethylene and perfluoroalkoxyalkane, with an external stainless steel braided mesh to enhance pressure resistance, or fluororubber or ethylene propylene rubber composite hose for specific working conditions, to withstand the corrosion of phosphoric acid and fluorine-containing media and meet the flexibility requirements during maintenance. The matching second flange 5 is made of 316L stainless steel and is compatible with the material of the connecting hose 4 and the phosphoric acid working conditions to ensure sealing and corrosion resistance when connected to the connecting hose 4, the mixer body and external pipelines, and to avoid media leakage or component corrosion damage.

[0022] The auxiliary maintenance component is a key structure for reducing equipment maintenance difficulty and improving maintenance efficiency. The auxiliary maintenance component includes a connecting hose 4 and second flanges 5 at both ends. One end of the connecting hose 4 is connected to the first flange 2 of the mixer body through the second flange 5, and the other end of the connecting hose 4 is connected to an external pipeline. During maintenance, it is not necessary to remove the entire mixer body. Only the first flange 2 at the connection between the mixer body and the external pipeline needs to be removed. By using the flexibility of the connecting hose 4 to rotate the mixer body and make it offset from the external pipeline, the internal mixing component 3 can be directly removed for cleaning or replacement. This reduces the disassembly and assembly time to half of the original time, and significantly reduces the downtime costs caused by equipment maintenance in the phosphate chemical industry.

[0023] The rotating support rod 6 includes two sets of fixed rods 601. One end of the fixed rod 601 is fixed to the two sets of second flanges 5 by screws, and the other end of the two sets of fixed rods 601 is rotatably connected to the two ends of the rotating rod 602.

[0024] The rotating support rod 6 is a support structure that stabilizes the rotation of the mixer body. It consists of two sets of fixed rods 601 and one set of rotating rods 602. The two sets of fixed rods 601 are fixed to the second flanges 5 at both ends of the connecting hose 4 by screws. The two ends of the rotating rod 602 are rotatably connected to the fixed rods 601. The rotating support rod 6 can provide a stable support point when the mixer body is rotated for maintenance, avoiding the main body from shaking or tilting due to the softness of the connecting hose 4. This ensures that the operator can adjust the position of the main body smoothly and accurately. At the same time, it can also enhance the connection stability between the connecting hose 4 and the installation pipe 1 during normal operation of the equipment, preventing excessive deformation of the connecting hose 4 due to medium pressure or its own weight.

[0025] In practical use, after moving the device to the designated position, fix the first flange 2 at one end of the installation pipe 1 to the external pipeline, then connect and fix the second flange 5 at the other end of the connecting hose 4 to the external pipeline, and connect the dosing port at the top of the installation pipe 1 to complete the overall installation; then open the external pipeline valve to allow media such as phosphoric acid and ammonium phosphate slurry to flow into the installation pipe 1. When the media flows through the area where the left-hand spiral blade 303 and the right-hand spiral blade 304 intersect, it will be cut, diverted, and rotated to mix, achieving a uniform mixing effect; when maintenance is required, first close the media delivery valve. After the medium inside the pipe is emptied, remove the connecting bolts between the first flange 2 at the end of the installation pipe 1 furthest from the connecting hose 4 and the external pipe. Utilizing the flexibility of the connecting hose 4, rotate the installation pipe 1 using the rotating rod 602 of the rotating support rod 6 as the fulcrum, so that it is misaligned with the external pipe. Then, pull out the internal mixing component 3 along the direction of the limiting groove 8, clean the crystals and solid particles on the surface of the mixing component 3, or replace damaged parts. After maintenance, reinstall the mixing component 3 into the installation pipe 1 in the original direction, reverse the operation to reset the installation pipe 1, and retighten the flange connection to restore the device operation.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
