Description

Technical Field

[0001] This invention relates to a separator, specifically a composite solid-liquid separator and its usage method, belonging to the technical field of environmental protection machinery and separation equipment. Background Technology

[0002] Solid-liquid separation is a key process in environmental protection, agriculture, food and chemical industries. For the treatment of highly viscous materials such as sludge, livestock and poultry manure and kitchen waste, the industry is constantly pursuing higher dehydration rates, greater processing capacity and more stable operating performance.

[0003] In existing technologies, such as the vibrating solid-liquid separator disclosed in CN205073760U, a preliminarily combined two principles by setting an extruder device below the end of the vibrating screen bed. However, the extruder device in this scheme is only an independent auxiliary component, and its connection with the front-end vibrating screen may not be tight enough in terms of structural integration and power transmission. The solid material generated by the vibrating screen enters the extruder in a loose state, and there is room for improvement in the efficiency of pretreatment and dewatering pressure formation. Moreover, the overall structural compactness and collaborative control capabilities can be further optimized. Another example is the fully automatic composite solid-liquid separator disclosed in CN104941310A. The linear vibrating solid-liquid separator assembly and the screw extrusion solid-liquid separator assembly are arranged vertically on the same frame. The vibrating discharge port of the vibrating screen is directly connected to the slag inlet of the screw extruder, realizing continuous operation of preliminary screening and deep extrusion dewatering of materials. However, in the screw extrusion assembly designed in the prior art, the front end of the screw is designed to be suspended, supported only by the rear drive shaft. This cantilever beam structure, when subjected to the enormous extrusion reaction force at the end over a long period, may affect the stability and lifespan of the main shaft operation and limit further increases in the final extrusion pressure, thus constraining the limit of dewatering dryness. Secondly, its extrusion dewatering is mainly achieved through the natural compression of the material propelled by the helical blades within the variable-diameter cavity and the formation of back pressure at the open dry material outlet at the end. For materials with high viscosity, controlling dewatering resistance and discharge stability may face challenges. Summary of the Invention

[0013] As a further embodiment of the present invention: the driving gear, the linkage gear, and the driven gear are all helical gear structures.

[0014] A method of using a composite solid-liquid separator includes the following steps: S1. Feeding and Primary Separation: The mixture to be processed is fed into the machine through the feed inlet, and the material falls onto the inclined separation screen of the first separation component; at the same time, the vibration component is activated to make the separation screen vibrate. Under the action of vibration, the material is distributed on the screen surface and moves forward. Liquid and fine particles pass through the screen holes to achieve primary separation. The primary separation liquid is discharged through the first liquid outlet, and the wet residue slides to the discharge end of the separation screen. S2. Receiving and Secondary Dewatering: The wet slag falls from the end of the separating screen and enters the inner screen unit through the notch at the top of the feed outer pipe and the feed inner screen on the second separating component; the separating motor is started to drive the guide roller and the spiral guide blade to rotate, pushing the slag forward; during the pushing process, the residual liquid in the slag is discharged through the inner screen unit under the action of centrifugal force and extrusion, and enters the gap between the outer pipe unit and the inner screen unit, and the secondary separated liquid is discharged through the second liquid outlet; S3. End-of-line extrusion and slag discharge: The pushed slag reaches the retaining ring at the end of the guide roller. Under the forced action of the screw thrust, the slag is squeezed out through the gap between the retaining ring and the rear flange seat, achieving deep dewatering. After being extruded, the dewatered dry slag falls into the slag collection hood and is finally discharged through the slag outlet. The beneficial effects of this invention are: 1. This invention comprises a frame assembly, a first separation assembly, a second separation assembly, and a vibration assembly. The discharge end of the first separation assembly is located directly above the inlet end of the second separation assembly. This integrated design makes the entire separator compact, reducing its footprint and facilitating installation and deployment in limited spaces, making it particularly suitable for industrial or agricultural environments with limited space. The frame assembly serves as the load-bearing foundation, ensuring a stable connection between the first separation assembly, the second separation assembly, and the vibration assembly, improving overall mechanical strength and operational stability, and preventing component displacement or damage due to vibration or load. 2. The first separation component of this invention includes an inclined separation screen, and the second separation component includes an outer tube unit, an inner screen unit, a guide roller, and spiral guide blades. The inner screen unit is fitted inside the outer tube unit, with a gap between them. The guide roller is rotatably mounted inside the inner screen unit. The spiral guide blades are fixedly connected to the roller body of the guide roller, and a retaining ring is also fixedly fitted onto the roller body of the guide roller. A rear flange is connected to the end of the outer tube unit. The retaining ring and the rear flange are located on the same plane, with a gap between them. The slag conveyed by the guide roller and the spiral guide blades is squeezed out through the gap between the retaining ring and the rear flange. The separation screen of the first separation component utilizes gravity to promote the distribution and flow of materials on the screen. In the first separation component, liquid is rapidly discharged through the screen holes, while solid material slides along the inclined surface to the discharge end, achieving preliminary and efficient solid-liquid separation. The structure of the outer tube unit and inner mesh unit of the second separation component, with gaps, forms a secondary separation channel. When material enters from the first separation component, solid is intercepted by the inner mesh unit, while liquid is discharged through the gap in the inner mesh, enhancing the separation effect. When the guide roller rotates, the spiral guide blades push the solid material forward, achieving continuous and stable slag discharge. The slag conveyed by the spiral guide blades is forced to be squeezed out through the gap between the retaining ring and the rear flange seat at the end, producing a squeezing dewatering effect, further removing residual liquid in the solid slag, increasing the dryness of the solid product, and forming a multi-stage separation to improve the solid-liquid separation efficiency.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1, as Figures 1 to 7 As shown, a composite solid-liquid separator includes a frame assembly 1. A first separation component 3, a second separation component 4, and a vibration component 5 are integrated on the frame assembly 1. The discharge end of the first separation component 3 is located directly above the inlet end of the second separation component 4. This integrated design makes the entire separator compact, reducing its footprint and facilitating installation and deployment in limited spaces, making it particularly suitable for industrial or agricultural environments with limited space. The frame assembly 1 serves as a load-bearing foundation, ensuring a stable connection between the first separation component 3, the second separation component 4, and the vibration component 5, improving overall mechanical strength and operational stability, and preventing component displacement or damage due to vibration or load. The first separation component 3 includes an inclined separation screen 32. The second separation component 4 includes an outer tube unit, an inner screen unit, a guide roller 45, and a spiral guide blade 46. The inner screen unit is fitted inside the outer tube unit, with a gap between them. The guide roller 45 is rotatably mounted inside the inner screen unit. The spiral guide blade 46 is fixedly connected to the roller body of the guide roller 45. A retaining ring 48 is also fixedly fitted onto the roller body of the guide roller 45. A rear flange seat 414 is connected to the end of the outer tube unit. The retaining ring 48 and the rear flange seat 414 are located on the same plane, with a gap between them. The slag conveyed by the guide roller 45 via the spiral guide blade 46 is squeezed out through the gap between the retaining ring 48 and the rear flange seat 414. The separation screen 32 of the first separation component 3 utilizes gravity to promote... The distribution and flow of materials on the screen allow liquids to be quickly discharged through the screen holes, while solid materials slide along the inclined surface to the discharge end, achieving preliminary and efficient solid-liquid separation. The structure of the outer tube unit and the inner screen unit of the second separation component 4, with gaps, forms a secondary separation channel. When materials enter from the first separation component 3, solids are intercepted by the inner screen unit, while liquids are discharged through the gaps in the inner screen, enhancing the separation effect. When the guide roller 45 rotates, the spiral guide blades 46 push the solid materials forward, achieving continuous and stable slag discharge. The slag conveyed by the spiral guide blades 46 is forced to be squeezed out through the gap between the retaining ring 48 and the rear flange seat 414 at the end, producing a squeezing dewatering effect, further removing residual liquid from the solid slag, increasing the dryness of the solid product, and forming a multi-stage separation to improve the efficiency of solid-liquid separation.

[0019] Example 2, in addition to all the technical features of Example 1, also includes: the frame assembly 1 includes a base 11 and a shell 12. A support frame 16 is fixedly connected to the base 11, and the shell 12 is fixedly connected to the support frame 16. A feed hood 13 is connected to the top of the shell 12. The body of the feed hood 13 is connected to two feed ports 14, one of which is horizontal and the other is vertical. The base 11 and the support frame 16 form a load-bearing skeleton to ensure stable operation of the separator in a vibrating working environment. The shell 12 provides comprehensive protection. The two feed ports 14 connected to the feed hood 13 in different directions give the separator good feeding adaptability. The horizontal feed port 14 facilitates connection to pipelines to achieve automated continuous feeding, while the vertical feed port 14 facilitates receiving materials from the upper hopper or manually poured materials, enabling the separator to easily adapt to various complex on-site process layouts and different feeding methods.

[0020] The base 11 has a first liquid outlet 15 connected to the middle part of its bottom. The base 11 also integrates an electrical control box 17, a control panel 18, and a drive motor 19. The electrical control box 17, control panel 18, and drive motor 19 are all located on the outside of the outer shell 12. Track wheels 2 are connected to both sides of the bottom of the base 11. The drive motor 19 is connected to the track wheels 2 for power transmission. The electrical control box 17 and control panel 18 are connected to the electrical components of the separator. The first liquid outlet 15 connected to the middle part of the bottom of the base 11 facilitates the centralized flow of the liquid separated in the primary stage. The electrical control box 17 and control panel 18 are integrated on the outside of the outer shell 12, making operation, monitoring, and maintenance more intuitive and convenient. The track wheels 2 are driven by the drive motor 19, enabling the separator to move. It is suitable for sewage treatment, river dredging, agricultural manure treatment, and other operating environments that require frequent relocation or have complex terrain. This improves the mobility and working efficiency of the separator and reduces the auxiliary equipment and manpower required for relocation.

[0021] In Example 3, in addition to all the technical features in Example 1, the first separation component 3 also includes a frame 31. The separation screen 32 is fixedly connected to the frame 31 on both sides. Several connecting seats 33 are fixedly connected between the frame 31 and the support frame 16. By setting the frame 31 to provide support for the separation screen 32, the separation screen 32 is effectively prevented from deforming or tearing under material impact and continuous vibration, ensuring effective screening area and screening accuracy. The frame 31 is firmly fixed to the support frame 16 by several connecting seats 33, realizing a rigid and stable connection between the separation screen 32 and the frame. This can effectively disperse vibration load and material impact force, avoid stress concentration, and ensure long-term stable screening efficiency.

[0022] The outer tube unit includes an infeed outer tube 42 and a guide outer tube 43. The inner mesh unit includes an infeed inner mesh 410 and a guide inner mesh 412. The infeed inner mesh 410 is fitted inside the infeed outer tube 42. Both the top of the infeed inner mesh 410 and the top of the infeed outer tube 42 have notches located directly below the inclined bottom end of the separating screen 32. The guide inner mesh 412 is fitted inside the guide outer tube 43. A separating motor 41 is coaxially and fixedly connected to the front end of the guide roller 45. The guide roller 45 guides the material... The end is fixedly fitted with a bearing 47, and the end of the feed guide tube 43 is connected to a support frame 415. A bearing seat 416 is fixedly connected to the frame of the support frame 415, and the bearing 47 is rotatably connected in the bearing seat 416. The notch groove at the top of the feed inner screen 410 and the feed outer tube 42 is located directly below the inclined bottom of the separation screen 32, ensuring that the solid material falling from the first separation component 3 accurately enters the feed inner screen 410, avoiding material scattering or blocking the inlet, and improving the efficiency and smoothness of material transfer. The inner guide net 412 is fitted inside the outer guide tube 43 to form a continuous separation channel. Solid materials are conveyed within the inner guide net 412, while liquids are discharged through the mesh into the gaps of the outer guide tube 43, achieving secondary separation. The front end of the guide roller 45 is coaxially connected to the separation motor 41 for direct drive. The end of the guide roller 45 is fixedly fitted with a bearing 47 and fixed to the support frame 415 via a bearing seat 416, ensuring the rotational stability and axial positioning of the guide roller 45 and reducing vibration and wear. The support frame 415 is connected to the end of the outer guide tube 43, providing stable support for the bearing seat 416, enhancing the rigidity of the entire guide system, and preventing deformation due to material compression or vibration.

[0023] A front flange seat 49 is fixedly connected between the body of the separating motor 41 and the feed outer pipe 42. A rear flange seat 414 is fixedly connected between the feed outer pipe 42 and the guide outer pipe 43. The feed inner mesh 410 and both ends of the feed outer pipe 42 are clamped and fixed between the front flange seat 49 and the docking flange 411. Several retaining rings 413 are fitted on the mesh body of the guide inner mesh 412, and the retaining rings 413 are locked in the gap between the feed inner mesh 410 and the feed outer pipe 42. The front flange seat 49 firmly fixes the separating motor 41 to the feed outer pipe 42, ensuring the coaxiality between the separating motor 41 and the guide roller 45, and preventing loosening or misalignment during operation. The rear flange seat 414 connects the feed outer pipe 42 and the guide outer pipe 43. 3. This design facilitates easy docking and disassembly of the two pipe sections, making transportation, assembly, and maintenance convenient. The flange connection also provides excellent sealing to prevent liquid leakage. The two ends of the feed inner mesh 410 and the feed outer pipe 42 are clamped and fixed between the front flange seat 49 and the docking flange 411, ensuring the accurate positioning of the feed inner mesh 410 in the pipe and preventing it from moving or rotating due to material flow or vibration, thus ensuring a uniform separation gap. The retaining ring 413 fixes the relative position of the guide inner mesh 412, preventing it from sliding or twisting axially during the material guiding process. At the same time, the multiple settings of the retaining ring 413 provide multi-point support, ensuring that the gap between the guide inner mesh 412 and the outer pipe unit remains consistent, which is conducive to smooth liquid flow and reduces the risk of blockage.

[0024] The bottom end of the outer feed pipe 43 is connected to a second liquid outlet 418. A slag collection hood 44 is installed at the feed end of the outer feed pipe 43. A support frame 415 is placed inside the slag collection hood 44. A slag outlet 417 is opened at the bottom end of the slag collection hood 44. A rear flange seat 414 connects the outer feed pipe 43 and the slag collection hood 44, and the support frame 415 is fixedly connected to the rear flange seat 414. The second liquid outlet 418 is located at the bottom end of the outer feed pipe 43 and is used to collect the secondary liquid separated from the inner feed net 412 and discharge it centrally. It works in conjunction with the first liquid outlet 15 to achieve liquid... The slag collection hood 44 is used to receive solid slag material squeezed out from the gap between the retaining ring 48 and the rear flange seat 414, and discharge it through the slag outlet 417 at the bottom end, which facilitates the centralized collection or subsequent treatment of slag material. The guide pipe 43 is connected to the slag collection hood 44 through the rear flange seat 414 to ensure a firm and sealed connection, prevent slag or liquid leakage, and facilitate the disassembly, cleaning or replacement of the slag collection hood 44. The support frame 415 is fixedly connected to the rear flange seat 414 to reduce vibration transmission and ensure the smooth operation of the bearing seat 416 and the guide roller 45.

[0025] Example 4: In addition to all the technical features in Example 1, this example also includes: a vibration assembly 5 comprising a driving gear 51, a linkage gear 52, a driven gear 53, a driven rod 54, an oscillator 55, a transmission rod 56, and a mounting base 57. The mounting base 57 is fixed to the top of the housing 12. The driving gear 51 is rotatably connected to the mounting base 57. The linkage gear 52 and the driven rod 54 are both rotatably connected to the mounting base 57. The driven gear 53 is coaxially fixed to the driven rod 54, and the linkage gear 52 meshes between the driving gear 51 and the driven gear 53. The oscillator 55 is fixed to the driven rod 54. The driving gear 51 is coaxially fixed to the transmission rod 56, which is connected to an external power transmission end. Component 5 generates vibration through gear transmission. Mounting base 57 provides a stable mounting platform, ensuring effective coupling between the vibration source and the separation screen 32 of the first separation component 3. The vibration transmission efficiency is high. The gear meshing structure of the driving gear 51, linkage gear 52, and driven gear 53 realizes smooth power transmission and speed-up or speed-down adjustment. The linkage gear 52 acts as an intermediate gear, making the rotation direction of the driven rod 54 coordinated with the transmission rod 56, optimizing vibration generation. When the driven rod 54 rotates, the vibrator 55 generates centrifugal force, thereby causing periodic vibration. This vibration is transmitted to the separation screen 32, promoting the jumping and distribution of materials on the screen, enhancing the screening effect, preventing materials from adhering to or clogging the screen holes, and improving processing capacity and separation efficiency.

[0026] The driving gear 51, the linkage gear 52, and the driven gear 53 are all helical gear structures, which improves the smoothness and efficiency of gear transmission, reduces tooth surface wear, extends gear service life, and reduces maintenance frequency and cost. Helical gears have a stronger load-bearing capacity and can transmit greater torque, making them suitable for applications in the vibration assembly 5 that require strong vibration, ensuring that the vibrator 55 can generate sufficient centrifugal force to effectively vibrate and separate the screen 32.

[0027] Example 5: A method of using a composite solid-liquid separator, comprising the following steps: S1. Feeding and Primary Separation: The mixture to be processed is fed into the machine through the feed inlet 14, and the material falls onto the inclined separation screen 32 of the first separation component 3; at the same time, the vibration component 5 is activated to make the separation screen 32 vibrate. Under the action of vibration, the material is distributed on the screen surface and moves forward. Liquid and fine particles pass through the screen holes to achieve primary separation. The primary separation liquid is discharged through the first liquid outlet 15, and the wet residue slides to the discharge end of the separation screen 32. S2. Receiving and Secondary Dewatering: The wet slag falls from the end of the separating screen 32 and enters the inner screen unit through the notch at the top of the feed outer pipe 42 and the feed inner screen 410 on the second separating component 4; the separating motor 41 is started to drive the guide roller 45 and the spiral guide blade 46 to rotate, pushing the slag forward; during the pushing process, the residual liquid in the slag is discharged through the inner screen unit under the action of centrifugal force and extrusion, and enters the gap between the outer pipe unit and the inner screen unit. The secondary separated liquid is discharged through the second liquid outlet 418. S3. End extrusion and slag discharge: When the pushed slag reaches the retaining ring 48 at the end of the guide roller 45, under the forced action of the spiral thrust, the slag is squeezed out through the gap between the retaining ring 48 and the rear flange seat 414 to achieve deep dewatering; after the dewatered dry slag is squeezed out, it falls into the slag collection hood 44 and is finally discharged through the slag outlet 417.

[0028] Working principle: The mixed material enters the separator through the feed inlet 14 and first falls on the inclined separation screen 32 of the first separation component 3. At the same time, the vibration component 5 starts to work. Its transmission rod 56 receives power and drives the drive gear 51. Through the linkage gear 52, it drives the driven gear 53 and the driven rod 54 to rotate, thereby causing the vibrator 55 fixed on the driven rod 54 to generate centrifugal vibration. This vibration is transmitted to the separation screen 32, causing the screen to generate high-frequency micro-amplitude vibration, which promotes the material to be evenly distributed on the screen surface and move forward quickly. In this process, the smaller solid particles and liquids pass through the mesh of the separation screen 32 to achieve preliminary separation. The liquid after preliminary separation is discharged through the first liquid outlet 15 set at the bottom of the frame component 1, while the remaining wet residue slides down the inclined screen surface to its discharge end. Subsequently, the slag falls into the second separation component 4 located directly below it by gravity, and enters the inner network unit through the notch slot at the top of the feed outer pipe 42 and the feed inner net 410. The starting separation motor 41 drives the guide roller 45 and the spiral guide blade 46 fixed on it to rotate synchronously. The spiral guide blade 46 continuously conveys the slag forward. During the conveying process, the residual liquid in the slag seeps out through the mesh of the inner network unit (including the feed inner net 410 and the guide inner net 412) under the action of centrifugal force and pressure, enters the gap between the outer pipe unit (including the feed outer pipe 42 and the guide outer pipe 43) and the inner network unit, and is finally discharged from the second liquid outlet 418 connected to the bottom of the guide outer pipe 43, realizing secondary deep separation. As the spiral guide blades 46 advance, the slag is conveyed to the retaining ring 48 at the end of the guide roller 45. At this time, under the forced action of the spiral thrust, the slag is squeezed out through the narrow gap reserved between the retaining ring 48 and the rear flange seat 414. During this process, it is subjected to strong mechanical compression and shearing, thereby further removing internal moisture and completing the final deep dewatering. After the dewatered dry slag is squeezed out, it falls into the slag collection hood 44 set at the end and is discharged from the machine through the slag outlet 417 at its bottom.
