Description

Technical Field

[0001] The utility model relates to the technical field of sodium hypophosphite production devices, and particularly relates to a filtering structure for sodium hypophosphite production. Background Art

[0002] The frame filter shows important application value in the field of sodium hypophosphite production. With characteristics such as a large filtering area, high efficiency, and high precision, it is widely used in the pretreatment of raw material liquids, the clarification of intermediate products, and the purification of final products. By effectively removing impurities and suspended solids in the liquid, the frame filter significantly improves the purity and quality of sodium hypophosphite products. At the same time, in environmental protection treatment, this filter also plays an important role, helping to reduce the pollutant concentration in wastewater or waste liquid and achieving environmental protection discharge standards. Therefore, in the production process of sodium hypophosphite, the frame filter is an indispensable key equipment and is of great significance for improving production efficiency and product quality.

[0003] During the process of filtering sodium hypophosphite raw materials using a frame filter press, the high-temperature raw materials will pass through the filter press, resulting in the internal heat dissipating or conducting to the outside, thereby reducing the temperature of the raw materials. During this temperature change process, sodium hypophosphite crystals may be generated inside the raw materials. This not only causes some effective components to be filtered out together with the waste residue, resulting in waste of effective components, but also reduces the overall productivity of sodium hypophosphite crystals. Therefore, effective measures need to be taken to optimize the filtering process to reduce heat loss and crystal formation and improve production efficiency and product quality. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a filtering structure for sodium hypophosphite production to solve the technical problem that when high-temperature raw materials pass through the filter press, the internal heat dissipates or conducts to the outside, resulting in a decrease in the temperature of the raw materials. During this process, due to the temperature decrease, sodium hypophosphite crystals may be generated inside the raw materials, causing waste of effective components.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A filtering structure for sodium hypophosphite production, including a support frame, a temperature control mechanism is arranged at the top of the support frame. The temperature control mechanism includes a first pipeline and a second pipeline. One end of the first pipeline and the second pipeline is connected and communicated through a return pipe. A support plate is arranged between the other ends of the first pipeline and the second pipeline. The other ends of the first pipeline and the second pipeline are respectively provided with a water inlet pipe and a water outlet pipe. Lifting ears are arranged at the top of the first pipeline and the second pipeline.

[0006] By adopting the above technical solution, the first pipeline and the second pipeline are hoisted and placed above the support frame. The limiting plate and the support column provide stable support, which ensures the stability and safety of the filtering structure and lays a solid foundation for subsequent operations. At the same time, the water inlet pipe and the water outlet pipe are connected to the external hot water storage device, and a liquid pump is used to transfer hot water into the pipeline. The hot water conducts internal energy to each frame plate through the pipeline wall to precisely control the temperature of the internal raw materials.

[0007] Furthermore, the first pipeline and the second pipeline are connected to the external hoisting device through hoisting ears.

[0008] By adopting the above technical solution, the installation and movement of the entire filtering structure become more convenient. With the hoisting device, the pipeline can be easily hoisted above the support frame without excessive manpower or complex tools, thus improving the installation efficiency and reducing the installation cost.

[0009] Furthermore, the water inlet pipe is connected to the external hot water storage device through a liquid pump, and the water outlet pipe is the hot water output pipe after use.

[0010] By adopting the above technical solution, hot water can be conveniently introduced into the first pipeline and the second pipeline. The operation of the liquid pump ensures the continuous supply of hot water, and the flow rate and temperature of the hot water can be adjusted according to needs, thereby achieving precise control of the temperature of the raw materials during the filtering process.

[0011] Furthermore, a plurality of frame plates are arranged inside the support frame and are linearly arranged at equal intervals along the length line of the support frame. Sliding plates are arranged on both the front and rear sides of the support frame to support the frame plates.

[0012] By adopting the above technical solution, the raw materials can be evenly distributed between each frame plate during the filtering process, ensuring the uniformity of the filtering effect. At the same time, the equidistant linear arrangement also helps to optimize the hydrodynamics during the filtering process and improves the filtering efficiency.

[0013] Furthermore, the cross-section of the first pipeline and the second pipeline is in an "L" shape structure, and the inner sides of the first pipeline and the second pipeline are in contact with the frame plates.

[0014] By adopting the above technical solution, the pipeline can better fit inside the support frame and be in contact with the frame plates. Such a structure ensures that when the hot water flows inside the pipeline, it can fully conduct internal energy to the frame plates, thereby effectively controlling the temperature of the raw materials during the filtering process.

[0015] Further, a limiting plate is provided on one side of the support frame. A feed pipe and a discharge pipe are provided on the limiting plate. A hydraulic cylinder is provided on the other side of the support frame. A push plate is provided at the telescopic end of the hydraulic cylinder.

[0016] By adopting the above technical solution, the feed pipe and the discharge pipe are respectively used for the entry of raw materials and the discharge of the filtered product, ensuring the continuity and efficiency of the filtration process.

[0017] Further, support columns are provided on both sides of the hydraulic cylinder for supporting the first pipeline and the second pipeline.

[0018] By adopting the above technical solution, the support columns provide stable support for the first pipeline and the second pipeline. The support columns can effectively disperse the weight and pressure borne by the pipelines, ensuring that the pipelines will not deform or be damaged during long-term use, thereby protecting the integrity and stability of the filtration structure.

[0019] In summary, the main beneficial effects of the present utility model are as follows:

[0020] With the temperature control mechanism of the present utility model, by using an external hoisting device, the first pipeline and the second pipeline are hoisted through the hoisting ears and placed above the support frame. Then, the water inlet pipe and the water outlet pipe are connected to an external hot water storage device. In this way, hot water can be pumped into the first pipeline and the second pipeline by an external liquid pump. When the hot water enters the pipelines, its internal energy is conducted through the pipe walls of the pipelines to the inside of each frame plate. In this process, the hot water plays a role in temperature control, ensuring that the raw materials in the frame plates will not crystallize excessively due to heat loss during the filtration process. In this way, gentle and stable temperature control operations can be achieved, the productivity of sodium hypophosphite is significantly improved, and at the same time, excessive waste of effective costs is reduced. This filtration structure optimizes the production process of sodium hypophosphite through precise temperature control. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will describe the embodiments according to the overall structure of the present invention.

[0030] Embodiment 1:

[0031] A filtering structure for the production of sodium hypophosphite, such as Figures 1-4As shown in the figure, it includes a support frame 1. A temperature control mechanism 3 is provided at the top of the support frame 1. The temperature control mechanism 3 includes a first pipeline 301 and a second pipeline 302. One ends of the first pipeline 301 and the second pipeline 302 are connected and communicated through a return pipe 303. A support plate 304 is arranged between the other ends of the first pipeline 301 and the second pipeline 302. Water inlet pipes 305 and water outlet pipes 306 are respectively arranged at the other ends of the first pipeline 301 and the second pipeline 302. Lifting lugs 308 are arranged at the tops of the first pipeline 301 and the second pipeline 302 to lift and place the first pipeline 301 and the second pipeline 302 above the support frame 1. The limiting plate 201 and the support column 307 provide stable support. This step ensures the stability and safety of the filtering structure and lays a solid foundation for subsequent operations. At the same time, the water inlet pipes 305 and the water outlet pipes 306 are connected and communicated with an external hot water storage device. A liquid pump is used to transfer hot water into the pipeline. The hot water conducts internal energy through the pipeline wall to each frame plate 204 to precisely control the temperature of the internal raw materials. This measure effectively avoids excessive heat dissipation of the raw materials during the filtering process, significantly reduces the crystallization degree of sodium hypophosphite, and thus improves the production rate and reduces the excessive waste of effective costs.

[0032] Refer to Figure 1 , Figure 3 , the first pipeline 301 and the second pipeline 302 are connected to an external lifting device through the lifting lugs 308, making the installation and movement of the entire filtering structure more convenient. With the lifting device, the pipeline can be easily lifted above the support frame 1 without excessive manpower or complex tools, thus improving the installation efficiency and reducing the installation cost. At the same time, the setting of the lifting lugs 308 also ensures the stability and safety of the pipeline during the lifting process. They can bear the weight of the pipeline and prevent the pipeline from shaking or falling off during the lifting or use process, thereby protecting the filtering structure from damage and ensuring the smooth progress of the production process.

[0033] Refer to Figure 1 , Figure 3 , Figure 4 , the water inlet pipe 305 is connected and communicated with an external hot water storage device through a liquid pump. The water outlet pipe 306 is an output pipe for hot water after use, enabling hot water to be conveniently introduced into the first pipeline 301 and the second pipeline 302. The operation of the liquid pump ensures the continuous supply of hot water and can adjust the flow rate and temperature of the hot water as needed, thus achieving precise control of the temperature of the raw materials during the filtering process. At the same time, as an output pipe for hot water after use, the water outlet pipe 306 can timely discharge the hot water that has conducted internal energy and completed the temperature control task. This not only avoids the retention and overheating of hot water in the pipeline but also ensures the continuous and stable operation of the filtering structure. In addition, the discharged hot water can be recycled and reused, thereby improving the utilization efficiency of resources and reducing the production cost.

[0034] Refer to Figure 1 、 Figure 2 On the inner side of the support frame 1, a plurality of frame plates 204 are provided, and they are arranged in an equidistant linear pattern along the length line of the support frame 1. Sliding plates 205 are provided on both the front and rear sides of the support frame 1 to support the frame plates 204, enabling the raw materials to be evenly distributed between the frame plates during the filtration process, ensuring the uniformity of the filtration effect. At the same time, the equidistant linear arrangement also helps to optimize the hydrodynamics during filtration, improving the filtration efficiency. Also, the sliding plates 205 support the frame plates 204, allowing the frame plates 204 to be easily installed, disassembled or adjusted in position when needed, enhancing the flexibility and maintainability of the filtration structure, and strengthening the overall stability and durability of the filtration structure.

[0035] Embodiment 2:

[0036] Refer to Figure 3 、 Figure 4 The cross-sections of the first pipeline 301 and the second pipeline 302 are in an "L" - shaped structure. The inner sides of the first pipeline 301 and the second pipeline 302 are in contact with the frame plates 204, enabling the pipelines to better fit on the inner side of the support frame 1 and be in contact with the frame plates 204. Such a structure ensures that when hot water flows inside the pipelines, it can fully conduct internal energy to the frame plates 204, thereby effectively controlling the temperature of the raw materials during the filtration process. At the same time, the "L" - shaped structure also increases the contact area between the pipelines and the frame plates 204, improving the heat conduction efficiency, which allows the hot water to heat the frame plates 204 more evenly, avoiding local overheating or uneven temperature, further ensuring the stability and consistency of the filtration effect, and also making the pipelines more stable during installation and fixation, enhancing the overall stability and durability of the filtration structure.

[0037] Refer to Figure 1 、 Figure 2 On one side of the support frame 1, a limiting plate 201 is provided. An inlet pipe 401 and an outlet pipe 402 are provided on the limiting plate 201. On the other side of the support frame 1, a hydraulic cylinder 202 is provided. A push plate 203 is provided at the telescopic end of the hydraulic cylinder 202. The inlet pipe 401 and the outlet pipe 402 are respectively used for the entry of raw materials and the discharge of filtered products, ensuring the continuity and high efficiency of the filtration process. Also, on the other side of the support frame 1, a hydraulic cylinder 202 is provided, and the push plate 203 connected to its telescopic end can compress or push the raw materials on the frame plates 204 when needed, thereby helping to improve the filtration efficiency and effect. The use of the hydraulic cylinder 202 provides strong power support, enabling the push plate 203 to easily meet various filtration requirements, further enhancing the practicality and flexibility of the filtration structure.

[0038] Refer to Figure 1 、Figure 2 On both sides of the hydraulic cylinder 202, support columns 307 are provided to support the first pipeline 301 and the second pipeline 302. The support columns 307 provide stable support for the first pipeline 301 and the second pipeline 302. The support columns 307 can effectively disperse the weight and pressure borne by the pipelines, ensuring that the pipelines will not deform or be damaged during long-term use, thus protecting the integrity and stability of the filtration structure. At the same time, the setting of the support columns 307 also helps to optimize the overall layout of the filtration structure. They closely join the filtration device with the first pipeline 301 and the second pipeline 302 to form a compact and stable filtration system, which not only improves the filtration efficiency, but also makes the filtration structure easier to install, maintain and operate, reducing the production cost and labor intensity.

[0039] The implementation principle of the present utility model is as follows: First, the first pipeline 301 and the second pipeline 302 are hoisted by an external hoisting device through the hoisting ear 308, and then placed above the support frame 1, and the limiting plate 201 and the support columns 307 are used to support them. Subsequently, the water inlet pipe 305 and the water outlet pipe 306 are connected to an external hot water storage device, and at the same time, an external liquid pump is used to transfer hot water into the first pipeline 301 and the second pipeline 302. At this time, the internal energy in the hot water is conducted through the pipe walls of the first pipeline 301 and the second pipeline 302 to each frame plate 204 inside, controlling the temperature of the raw materials inside, avoiding excessive loss of heat during the filtration process of the raw materials, thereby reducing the crystallization degree of sodium hypophosphite inside, improving the productivity of sodium hypophosphite, and reducing the excessive waste of effective costs.

[0040] Parts not involved in the present utility model are the same as or can be implemented by the prior art, and will not be elaborated here too much.

[0041] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model, and they are not limitations of the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
