Description

Technical Field

[0001] This utility model belongs to the field of solid-liquid separation technology, and specifically relates to a solid-liquid eddy current separation heat exchanger. Background Technology

[0002] In numerous industrial production and environmental protection fields, the separation and treatment of solid-liquid mixtures is a common and crucial task. For example, in the coal industry, coal washing generates wastewater with high concentrations of suspended solids, containing large amounts of solid particles such as coal slime. This coal slime needs to be separated from the water to achieve water resource recycling and reduce environmental pollution. In wastewater treatment, whether it's removing suspended solids in the initial treatment stage or further purifying wastewater in the advanced treatment stage, effective separation of solid-liquid mixtures is essential. The separated solid and liquid phases often require temperature control to meet the requirements of subsequent processes. For instance, in some chemical production processes, the separated liquid may need to be heated or cooled to a specific temperature before the next reaction can proceed; cooling tower circulating water systems also require water cooling treatment.

[0003] Traditional solid-liquid separation methods, such as filtration using filter screens and discs, are prone to clogging, affecting separation efficiency and equipment operation. While centrifugation offers higher separation efficiency, it is costly, energy-intensive, and highly sensitive to flow rate requirements. Temperature control involves transferring the separated filtrate to a dedicated heat exchanger, increasing floor space and investment while also leading to heat loss and reduced energy efficiency. Therefore, a more efficient, stable, and cost-effective solid-liquid separation device is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a solid-liquid vortex separation heat exchanger, which has the advantages of achieving good solid-liquid separation effect and improving the smoothness of slag discharge.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a solid-liquid vortex separation heat exchanger, comprising a spiral plate compartment and a support mechanism, wherein a top sealing plate and a bottom sealing plate are respectively bolted to the top and bottom of the spiral plate compartment, a medium inlet pipe and a vortex outlet pipe are respectively bolted to the bottom of the bottom sealing plate and the top of the top sealing plate, a vortex inlet pipe and a medium outlet pipe are respectively injection molded to the front and back of the top sealing plate, a settling chamber is bolted to the bottom of the bottom sealing plate, a spiral baffle is provided inside the spiral plate compartment, a shell is bolted to the bottom of the settling chamber, a transmission rod is rotatably connected inside the shell, a spiral blade is bolted to the surface of the transmission rod, a motor is fixedly sleeved to the other end of the transmission rod, and a discharge port is connected to the bottom of the shell.

[0006] The above technical solution enables integrated solid-liquid separation and filtrate heating, allowing the separated filtrate to directly exchange heat with the heat exchange medium internally to meet temperature rise or fall requirements. This not only improves production efficiency and saves equipment space but also reduces energy consumption. Furthermore, it enhances slag discharge flow, forcibly pushing the slag forward to prevent accumulation and blockage at the discharge port, ensuring continuous and uninterrupted slag discharge, making it highly practical.

[0007] The present invention is further configured such that the support mechanism includes a base plate, the base plate is disposed at the bottom of the bottom sealing plate, and support rods are welded at equal intervals between the top of the base plate and the bottom sealing plate.

[0008] By adopting the above technical solution, the equipment can be placed on the ground with good stability through the setting of the base plate and support rod.

[0009] The present invention is further configured such that a metal filter plate is bolted to the inside of the housing.

[0010] The above technical solution allows for further separation of the filtrate from the slag material inside the shell by using metal filter plates.

[0011] The present invention is further configured such that a drain valve is connected through one side of the housing.

[0012] The above technical solution allows the filtrate separated inside the shell to be discharged outwards via the drain valve.

[0013] The present invention is further configured such that a protective cover is bolted to the other side of the housing, and a heat dissipation groove is provided on the other side of the protective cover, and a dustproof net is bolted to the inside of the heat dissipation groove.

[0014] The above technical solution, through the installation of protective covers, heat dissipation slots and dustproof nets, can protect the motor and prevent it from malfunctioning or being damaged by collisions with external objects.

[0015] The present invention is further provided that the surfaces of the spiral plate compartment, the top sealing plate and the bottom sealing plate are all coated with anti-corrosion coating.

[0016] By adopting the above technical solution, the anti-corrosion and moisture-proof effects of the spiral plate compartment, top sealing plate and bottom sealing plate can be improved through the application of anti-corrosion coating.

[0017] In summary, this utility model has the following beneficial effects: 1. By introducing the material requiring solid-liquid separation through the cyclone feed pipe, the internal spiral baffles create a vortex upon entry, generating centrifugal force. This causes the material to stratify according to density, with heavier materials accumulating on the outer wall and flowing to the cyclone discharge pipe, lighter materials overflowing through the cyclone discharge pipe, and heavier materials settling in the settling chamber. The medium then flows in through the medium inlet pipe, undergoes heat exchange within the spiral baffle, and flows out through the medium outlet pipe. This integrated solid-liquid separation and filtrate heating function allows the separated filtrate to directly exchange heat with the heat exchange medium internally, achieving temperature increases or decreases as needed. This not only improves production efficiency and saves equipment space but also reduces energy consumption. 2. The heavy material deposited in the settling chamber falls into the shell, where the metal filter plate intercepts the slag, while the solution separates downwards through the mesh. Activating the metal filter plate drives the transmission rod and spiral blades to rotate. As the spiral blades rotate, they push the slag upwards and backwards. When the slag reaches the highest point, it is discharged through the discharge port into a pre-prepared container. This improves the smoothness of slag discharge, forcibly pushes the slag forward, avoids accumulation and blockage at the discharge port, ensures continuous and uninterrupted slag discharge, and is highly practical.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example 1: refer to Figure 1 , Figure 2 and Figure 3A solid-liquid vortex separation heat exchanger includes a spiral plate compartment 1 and a support mechanism 8. A top sealing plate 2 and a bottom sealing plate 3 are respectively bolted to the top and bottom of the spiral plate compartment 1. A medium inlet pipe 4 and a vortex outlet pipe 5 are respectively bolted through the bottom of the bottom sealing plate 3 and the top of the top sealing plate 2. A vortex inlet pipe 6 and a medium outlet pipe 7 are respectively injection molded on the front and back of the top sealing plate 2. A settling chamber 9 is bolted through the bottom of the bottom sealing plate 3. A spiral baffle 18 is provided inside the spiral plate compartment 1. The spiral baffle 18 has a conical three-dimensional spiral structure, that is, the spiral diameter at the top is larger than the spiral diameter at the bottom. The vortex inlet pipe 6 is located at the top of the spiral baffle 18, and the settling chamber 9 is located at the bottom of the spiral baffle 18. A spiral flow channel is formed between the spiral baffles 18. The spiral inlet pipe 6 is connected to the settling chamber 9 through the spiral flow channel. The settling chamber 9 is vertically connected to the spiral outlet pipe 5. The material to be separated into solid and liquid enters through the spiral inlet pipe 6. Due to the action of the internal spiral baffles, a vortex is formed after entering the spiral flow channel, generating centrifugal force. This causes the incoming material to stratify according to density. The heavier materials accumulate on the outer wall and flow to the spiral outlet pipe 5, while the lighter materials overflow to the spiral outlet pipe 5 and flow out. The heavier materials are deposited in the settling chamber 9. Then, the medium flows in through the medium inlet pipe 4, undergoes heat exchange in the spiral plate compartment 1, and flows out through the medium outlet pipe 7. This achieves integrated solid-liquid separation and filtrate heating functions. The separated filtrate directly exchanges heat with the heat exchange medium inside to meet the temperature rise or fall requirements, which not only improves production efficiency and saves equipment space, but also reduces energy consumption.

[0022] refer to Figure 1 The support mechanism 8 includes a base plate 81, which is located at the bottom of the bottom sealing plate 3. Support rods 82 are welded at equal intervals between the top of the base plate 81 and the bottom sealing plate 3. Through the arrangement of the base plate 81 and the support rods 82, the equipment can be supported on the ground with good stability.

[0023] refer to Figure 1 , Figure 2 and Figure 3 The surfaces of the spiral plate compartment 1, the top sealing plate 2, and the bottom sealing plate 3 are all coated with anti-corrosion paint. The anti-corrosion and moisture-proof effects of the spiral plate compartment 1, the top sealing plate 2, and the bottom sealing plate 3 can be improved by the application of anti-corrosion paint.

[0024] Brief description of the usage process: The material to be separated into solid and liquid is introduced into the vortex inlet pipe 6. Due to the action of the internal spiral baffle, a vortex is formed after entering, generating centrifugal force, which causes the material to stratify according to density. The heavy material gathers on the outer wall and flows to the vortex outlet pipe 5, while the light material overflows into the vortex outlet pipe 5 and flows out. The heavy material is deposited in the settling chamber 9. The spiral baffle 8 is provided with a medium flow channel. The bottom end of the medium flow channel is connected to the medium inlet pipe 4 and the top end is connected to the medium outlet pipe 7. The medium flows in from the medium inlet pipe 4, undergoes heat exchange in the spiral plate compartment 1, and flows out from the medium outlet pipe 7.

[0025] By employing spiral plate heat exchange and eddy current separation technology, this method addresses the solid-liquid separation and heat exchange requirements of processes involving waste cooking oil and slurry. It also solves problems such as material blockage in conveying pipelines and unstable conveying volumes. The eddy current generated by the spiral plate heat exchange is utilized in solid-liquid separation, reducing the power required for material feeding and saving operating costs. Furthermore, the heat exchange process helps to alter the viscosity and density of the material, improving separation efficiency and overcoming the limitations of spiral plate heat exchangers on material requirements, thus expanding its application range.

[0026] Example 2: refer to Figure 1 A solid-liquid vortex separation heat exchanger includes a settling chamber 9 with a bottom-mounted, upwardly inclined shell 10. A drive rod 11 is rotatably connected inside the shell 10, and spiral blades 12 are bolted to the surface of the drive rod 11. A motor 13 is fixedly sleeved at the other end of the drive rod 11. A discharge port 14 is connected to the bottom of the shell 10 at the end furthest from the settling chamber 9. The discharge port 14 is connected to the top of a metal filter plate 15 to prevent slag from entering the filtrate channel between the metal filter plate 15 and the shell 10. Heavy materials deposited in the settling chamber 9 will flow downwards. The slag falls into the housing 10, where the metal filter plate 15 intercepts it, while the solution separates downwards through the mesh. Activating the metal filter plate 15 drives the transmission rod 11 and the spiral blade 12 to rotate. As the spiral blade 12 rotates, it pushes the slag upwards and backwards. When the slag reaches its highest point, it is discharged through the discharge port 14 into a pre-prepared container. This improves the smoothness of slag discharge, forcibly pushes the slag forward, avoids accumulation and blockage at the discharge port, ensures continuous and uninterrupted slag discharge, and is highly practical.

[0027] refer to Figure 1 A metal filter plate 15 is bolted inside the housing 10. The metal filter plate 15 is parallel to the transmission rod 11 and located below the spiral blade 12. A drainage channel is formed between the metal filter plate 15 and the bottom of the housing 10. The metal filter plate 15 can further separate the filtrate that enters the slag inside the housing 10.

[0028] refer to Figure 1A drain valve 16 is installed at the bottom of the drain channel of the housing 10. The drain valve 16 allows the filtrate separated inside the housing 10 to be discharged to the outside.

[0029] refer to Figure 1 A protective cover 17 is bolted to the other side of the housing 10. A heat dissipation groove is provided on the other side of the protective cover 17. A dustproof net is bolted inside the heat dissipation groove. The protective cover 17, the heat dissipation groove and the dustproof net can protect the motor 13 and prevent the motor 13 from being damaged or malfunctioning due to collisions with external objects.

[0030] Brief description of the operation process: The heavy material deposited in the settling chamber 9 falls into the shell 10. The metal filter plate 15 in the shell 10 intercepts the slag, while the solution is separated downwards through the mesh of the metal filter plate 15. The metal filter plate 15 is activated to drive the transmission rod 11 and the spiral blade 12 to rotate. When the spiral blade 12 rotates, it pushes the slag upwards and backwards. When the slag is transported to the highest point, it is discharged into the pre-prepared container through the discharge port 14.

[0031] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
