Description

Technical Field

[0001] This utility model belongs to the field of graphite processing technology, and specifically relates to a high-purity graphite pressure filtration and separation device with a spiral guide plate. Background Technology

[0002] In the field of graphite processing and resource recycling, the solid-liquid separation process directly affects the purity, particle size, and production efficiency of graphite products. At present, plate and frame filter presses rely on static pressure to achieve solid-liquid separation, requiring frequent manual disassembly and assembly of filter plates for filter cake cleaning and filter cloth washing. The single-processing capacity is limited and the degree of automation is low. Although centrifugal separation equipment can operate continuously, the high-speed rotation causes violent collisions between graphite particles, which can easily lead to particle size damage. In addition, the equipment has high sealing requirements and high energy consumption. Furthermore, some existing devices employ simple cylindrical chambers and planar flow guide structures, which have been found to have the following drawbacks during use: First, the material flows through the chamber in a short and uneven manner, easily forming local accumulations and resulting in low separation efficiency; second, the traditional planar flow guide design cannot effectively guide the directional movement of materials, making it difficult to fully utilize pressure to achieve solid-liquid separation, and the liquid discharge resistance is high, resulting in a persistently high moisture content in the filter cake; third, the separated filter cake needs to be manually transferred, the filter box is inconvenient to disassemble, and the traditional bottom liquid guiding channel of the filter box is mostly designed horizontally or with a gentle slope, resulting in a large amount of liquid residue, which can easily cause secondary pollution and waste of resources. Therefore, existing separation devices suffer from short flow guide paths and incomplete solid-liquid separation, leading to a high moisture content in the filter cake. Utility Model Content

[0003] In view of this, the present invention provides a high-purity graphite pressure filtration and separation device with a spiral guide plate, which can solve the problem of high moisture content in filter cake caused by short flow path and incomplete solid-liquid separation.

[0004] This utility model is implemented as follows:

[0005] This utility model provides a high-purity graphite pressure filtration and separation device with a spiral guide plate, including a pressure filtration chamber. The pressure filtration chamber is equipped with a spiral extrusion assembly. The pressure filtration chamber includes an inlet end and an outlet end. One end of the outlet end is movably connected to a filter box via a guide rod. The filter box is equipped with a filter groove. An inclined liquid guiding channel is provided at the bottom of the filter groove. A liquid collection tank is provided at the bottom of the pressure filtration chamber. The filter groove and the filter box are detachably connected. A drain pump is provided inside the liquid collection tank.

[0006] The technical effects of the high-purity graphite pressure filtration separation device with a spiral guide plate provided by this utility model are as follows: By setting a spiral extrusion component inside the pressure filtration chamber, the material can be quickly introduced at the feed end and gradually extruded during its movement towards the output end, effectively extending the residence time and flow path of the material in the pressure filtration chamber, thus solving the problems of short material flow path and insufficient separation in the prior art; the filter box and filter tank are used to achieve high-precision solid-liquid separation, effectively reducing the moisture content of the filter cake, thus solving the problems of incomplete separation and high moisture content of the filter cake in the prior art; the inclined liquid guiding channel set at the bottom of the filter tank, combined with a variable cross-section design (wide inlet and narrow outlet), utilizes gravity and pressure difference to guide the liquid to flow quickly and smoothly to the collection tank at the bottom of the pressure filtration chamber, reducing liquid residue and avoiding secondary pollution and resource waste; a drain pump is set to facilitate the discharge of liquid inside the collection tank.

[0007] Based on the above technical solution, the high-purity graphite pressure filtration and separation device with a spiral guide plate of this utility model can be further improved as follows:

[0008] The spiral extrusion assembly includes a spiral guide plate and a motor. The output end of the spiral guide plate is fixedly connected to a central shaft, the motor is located outside the central shaft, and the other end of the central shaft is movably connected to the fin connecting seat.

[0009] The beneficial effect of adopting the above-mentioned improvement scheme is that the central shaft is driven to rotate by the motor, which in turn drives the spiral guide plate to rotate.

[0010] Furthermore, multiple sets of connecting fins are provided on the outer periphery of the fin connecting seat, and a coupling seat is provided in the middle of the fin connecting seat. The coupling seat is movably connected to the central shaft, and an output gap is provided between the connecting fins.

[0011] The beneficial effects of the above-mentioned improved scheme are as follows: Multiple sets of inclined connecting fins are arranged on the outer periphery of the finned connecting seat, with their ends fixedly connected to the inner wall of the filter press chamber. Their inclination angle matches the rotation direction of the spiral guide plate, providing guidance for the output material and causing it to form a spiral downward flow trajectory within the chamber, effectively preventing local accumulation and further improving separation efficiency. Simultaneously, the output gap between the connecting fins ensures that the compressed filter cake can be smoothly output, preventing blockage and solving the problems of easy material accumulation and poor filter cake output in existing devices.

[0012] Furthermore, the connecting fins are inclinedly arranged on the inner wall of the filter press chamber, and their ends are fixedly connected to the inner wall of the filter press chamber.

[0013] The beneficial effect of adopting the above-mentioned improvement scheme is that by setting inclined connecting fins, the output can be guided.

[0014] Furthermore, a feed trough is provided at the top of the feed end.

[0015] Furthermore, a guide groove is provided on the outside of the filter press chamber, and a guide rail is provided on the inner wall of the guide groove. The filter box is slidably connected to the guide rail through a guide rod.

[0016] Furthermore, a limit slider is provided at the end of the guide rod, which is used to limit the maximum displacement distance of the guide rod in conjunction with the guide rail.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by cooperating with the limit slider and the guide rail, the maximum displacement distance of the guide rod is limited, ensuring the stability of the filter box during the sliding process and preventing sealing failure or material leakage caused by excessive sliding.

[0018] Furthermore, the filter tank has filter mesh holes evenly arranged on its outer periphery, and a composite multi-layer filter screen is provided on the inner wall of the filter tank. The composite multi-layer filter screen includes a bottom coarse filter screen and an upper high-precision filter screen, and the composite multi-layer filter screen is detachably connected to the filter tank.

[0019] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the bottom coarse filter screen first intercepts large particulate impurities, and the upper high-precision filter screen further filters fine particles, realizing high-precision solid-liquid separation, effectively reducing the moisture content of the filter cake, and solving the problems of incomplete separation and high moisture content of the filter cake in the existing technology; the composite multi-layer filter screen and filter tank are detachable, which facilitates cleaning and replacement of the filter screen after clogging, as well as cleaning of the filter tank after the filter cake is collected, reducing equipment maintenance time and cost, and improving the continuous operation capability of the equipment.

[0020] Furthermore, the pitch of the spiral guide plate near the feed end is greater than the pitch near the output end, and the surface of the spiral guide plate is provided with staggered raised ribs.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the variable pitch design has a larger pitch at the feed end, which facilitates the rapid introduction of materials; the pitch at the output end gradually decreases, which gradually squeezes the materials; and the surface is provided with staggered raised ribs, which can increase the friction with the materials and enhance the squeezing effect.

[0022] Furthermore, the filter tank end is detachably connected to the filter box via connecting lugs and bolts on both sides.

[0023] Compared with existing technologies, the advantages of the high-purity graphite pressure filtration and separation device with a spiral guide plate provided by this utility model are as follows: the variable pitch spiral guide plate and raised ribs of the pressure filtration chamber and the spiral extrusion assembly extend the material residence time and enhance the extrusion; the material is uniformly fed into the interior through the feed trough; the fin connecting seat and the inclined connecting fins guide the material flow and prevent clogging; the guide rail and limit slider design of the pressure filtration chamber and the filter box are used to achieve stable movement of the filter box; the detachable composite multi-layer filter screen inside the filter box ensures high-precision separation; and the inclined liquid guiding channel and the liquid collection tank reduce liquid residue and achieve convenient and rapid liquid discharge.

[0031] like Figure 1-3The image shows an embodiment of a high-purity graphite pressure filtration and separation device with a spiral guide plate provided by this utility model. In this embodiment, a pressure filtration chamber 10 is included, wherein a spiral extrusion assembly 11 is provided inside the pressure filtration chamber 10.

A filter groove 131 is provided inside the filter box 13. An inclined liquid guiding channel 132 is provided at the bottom of the filter groove 131. A liquid collection tank 14 is provided at the bottom of the pressure filtration chamber 10. The filter groove 131 and the filter box 13 are detachably connected. A drain pump 141 is provided inside the liquid collection tank 14.

[0032] During use, graphite material is fed into the feed end. Under the action of the spiral extrusion assembly, the material moves towards the output end along the spiral guide plate and is gradually squeezed into the filter tank. The liquid passes through the composite multi-layer filter screen in the filter tank and flows into the collection tank at the bottom of the filter press chamber through the inclined liquid guiding channel at the bottom, completing the solid-liquid separation. The separated filter cake enters the filter box under the push of the spiral guide plate. After collection, the filter box is moved out of the device along the guide rail by the guide rod to realize the output of the filter cake. The liquid in the collection tank is discharged by the drain pump.

[0033] In the above technical solution, the spiral extrusion assembly 11 includes a spiral guide plate 111 and a motor 112. The output end of the spiral guide plate 111 is fixedly connected to a central shaft 113, the motor 112 is located outside the central shaft 113, and the other end of the central shaft 113 is movably connected to the fin connecting seat 114.

[0034] Furthermore, in the above technical solution, multiple sets of connecting fins 15 are provided on the outer periphery of the fin connecting seat 114, and a coupling seat is provided in the middle of the fin connecting seat 114. The coupling seat is movably connected to the central shaft 113, and an output gap is provided between the connecting fins 15.

[0035] Furthermore, in the above technical solution, the connecting fins 15 are inclinedly arranged on the inner wall of the filter press chamber 10, and the ends are fixedly connected to the inner wall of the filter press chamber 10.

[0036] Furthermore, in the above technical solution, a feed trough 16 is provided at the top of the feed end 101.

[0037] Furthermore, in the above technical solution, a guide groove is provided on the outside of the filter press chamber 10, and a guide slide rail is provided on the inner wall of the guide groove. The filter box 13 is slidably connected to the guide slide rail through the guide rod 12.

[0038] Furthermore, in the above technical solution, a limiting slider is provided at the end of the guide rod 12. The limiting slider is used to cooperate with the guide rail to limit the maximum displacement distance of the guide rod 12.

[0039] Furthermore, in the above technical solution, a compression spring is provided between the limiting slider and the guide rail, and the compression spring is used to provide resistance when the filter box is displaced.

[0040] Furthermore, in the above technical solution, filter mesh holes are evenly arranged on the outer periphery of filter tank 131, and a composite multi-layer filter screen is provided on the inner wall of filter tank 131. The composite multi-layer filter screen includes a bottom coarse filter screen and an upper high-precision filter screen, and the composite multi-layer filter screen is detachably connected to filter tank 131.

[0041] Furthermore, in the above technical solution, the pitch of the spiral guide plate 111 near the feed end 101 is greater than the pitch near the output end 102, and the surface of the spiral guide plate 111 is provided with staggered raised ribs.

[0042] Furthermore, in the above technical solution, the end of the filter tank 131 is detachably connected to the filter box 13 via connecting ears and bolts on both sides.

[0043] Specifically, the principle of this invention is as follows: A variable-pitch spiral guide plate of the spiral extrusion assembly is rotated by a motor, causing the material to move along a spiral path within the filter press chamber. During the process, the pitch gradually decreases to achieve progressive extrusion, and the raised ridges on the surface enhance the extrusion effect, extending the material's residence time for thorough separation. A feeding trough assists in uniform feeding, preventing localized accumulation. The inclined connecting fins of the finned connector guide the material output, preventing accumulation and blockage. The filter box is easily assembled and disassembled via guide rods, guide rails, and limiting sliders, ensuring stable operation. A multi-layer composite filter screen inside the filter tank performs high-precision filtration, and its detachable design facilitates maintenance. An inclined liquid guiding channel at the bottom of the filter tank, combined with a collection tank, utilizes gravity and pressure difference to achieve rapid liquid discharge and automated collection. All components work closely together, effectively solving existing technical problems and improving the efficiency and quality of graphite pressure filtration separation.
