[0050] The present invention provides a solid-liquid separation device that can continuously transport wet materials and separate moisture from the wet materials during the transport process, thereby achieving continuous processing of the wet materials and effectively solving the problem of exhaust gas leakage in the box. The following describes the present invention in conjunction with the accompanying drawings.

[0051] refer to Figure 1 and Figure 2 The solid-liquid separation device of the present embodiment includes a housing 100, a temperature control device 200, and a conveying device 300. The conveying device 300 is located in the housing 100 and is used to convey the wet material in a set direction. The housing 100 provides movement space for the conveying device 300 and the material being conveyed. The temperature control device 200 is used to adjust the temperature in the housing 100 to achieve moisture separation during the material conveying process.

[0052] The solid-liquid separation device also includes a distribution device 400. The box body 100 has a feed end 110 and a discharge end 120. The feed end 110 is provided with a feed port 111 connected to the interior of the box body 100, and the discharge end 120 is provided with a discharge port 121 connected to the interior of the box body 100. One end of the distribution device 400 is located outside the box body 100, and the other end extends into the box body 100 through the feed port 111. The distribution device 400 is used to transport materials from the outside of the box body 100 to the inside of the box body 100, thereby continuously feeding into the box body 100.

[0053] The conveying device 300 is located inside the housing 100 and has a material receiving end 301 and a material discharge end 302. The material receiving end 301 is connected to the material distribution device 400 inside the material feeding end 110 and is used to receive the material conveyed by the material distribution device 400. The conveying device 300 is used to convey the material toward the material discharge end 302. The material discharge end 302 corresponds to the material discharge port 121 and is used to convey the material toward the material discharge port 121. Therefore, wet material can be input into the housing 100 through the material distribution device 400, received by the conveying device 300 inside the housing 100, and conveyed toward the material discharge port 121. As a result, wet material can be continuously input into the housing 100 through the material distribution device 400, and can be continuously conveyed toward the material discharge port 121 through the conveying device 300, thereby enabling continuous inflow and outflow of material, avoiding intermittent waiting, and ensuring continuous production.

[0054] The temperature control device 200 is connected to the box body 100 and is used to adjust the internal temperature of the box body 100. Therefore, during the continuous transportation of the wet material, the temperature control device 200 adjusts the temperature inside the box body 100, can dry the material during the transportation process, and separate the moisture in the wet material, thereby realizing continuous processing of the wet material.

[0055] The solid-liquid separation device also includes a gas collecting device 500. The feed end 110 is further provided with a gas collecting port 112 communicating with the interior of the housing 100. The gas collecting device 500 is connected to the gas collecting port 112 and is used to exhaust gas from the feed end 110 to form a negative pressure around the feed port 111. During the continuous feeding process by the distribution device 400 and the continuous transportation and processing of the wet material within the housing 100, the gas collecting device 500 exhausts gas from the feed end 110, creating a negative pressure around the feed port 111. This can reduce or prevent the untreated gas inside the housing 100 from leaking into the external environment through the feed port 111. Therefore, the housing 100 can effectively prevent exhaust gas leakage without adopting a completely enclosed structure. Continuous feeding can be achieved by extending the distribution device 400 into the feed port 111, thereby achieving continuous processing of the wet material, which is conducive to meeting the needs of large-scale production.

[0056] The housing 100 may include side walls and a top wall. In some embodiments, a feed port 111 is provided on the side wall of the feed end 110 of the housing 100, and a gas collecting port 112 is provided on the top wall of the feed end 110 of the housing 100. The gas collecting device 500 is connected to the top wall of the housing 100 and communicates with the gas collecting port 112, thereby exhausting the feed end 110 from the top. Alternatively, the gas collecting port 112 may be provided on the side wall of the feed end 110, with a different orientation from the feed port 111, thereby exhausting the feed end 110 from the side. During the exhaust process, air flows through the feed port 111, forming a negative pressure / slightly negative pressure at and around the feed port 111. Under the action of the negative pressure / slightly negative pressure, the internal air can be prevented from escaping from the feed port 111, thereby effectively preventing dust-laden exhaust and odors in the housing 100 from leaking into the air, thereby preventing the working environment from being polluted.

[0057] refer to Figures 2 to 4 In some embodiments, the air collection device 500 includes an air collection hood 520 and multiple air collection pipes 510. One end of the air collection hood 520 is connected to the air collection port 112, and the other end is provided with multiple air outlets 523. For example, the number of air outlets 523 can be two, three, four, or more. As an example, the air collection hood 520 includes a first connecting hood 521 and four second connecting hoods 522. The first connecting hood 521 is connected to the air collection port 112. The four second connecting hoods 522 are distributed on the side of the first connecting hood 521 away from the air collection port 112 and connected to the first connecting hood 521. The four second connecting hoods 522 divert the air in the first connecting hood 521. The second connecting hoods 522 are provided with air outlets 523 on the end facing away from the first connecting hood 521, thereby forming four air outlets 523. Each gas outlet 523 is connected to a gas collecting pipe 510, and the gas collecting hood 520 is exhausted through multiple gas collecting pipes 510, which can improve the exhaust volume and exhaust efficiency. The gas collecting hood 520 is connected to the gas collecting port 112, and the air inside the feed end 110 is concentrated and exhausted from the gas collecting hood 520, effectively ensuring that negative pressure / micro-negative pressure is formed at the feed port 111.

[0058] In some embodiments, the gas collecting device 500 can exhaust the feed end 110 by connecting to an external negative pressure gas source, or the gas collecting device 500 may also include an exhaust fan 530, and each gas collecting pipe 510 is respectively provided with an exhaust fan 530. The exhaust fan 530 discharges the air inside the gas collecting pipe 510, thereby driving the gas inside the gas collecting hood 520 to flow into the gas collecting pipe 510, and then the gas inside the feed end 110 flows into the gas collecting hood 520 through the gas collecting port 112, thereby achieving exhaust of the feed end 110.

[0059] Alternatively, the gas collecting device 500 is further provided with a connecting pipe 540, to which each gas collecting pipe 510 is respectively connected. An exhaust fan 530 is provided in the connecting pipe 540. The exhaust fan 530 exhausts the air inside the connecting pipe 540, thereby driving the gas inside the gas collecting pipe 510 and the gas collecting cover 520 to flow into the gas collecting pipe 510, thereby allowing the gas inside the feed end 110 to flow into the gas collecting cover 520 through the gas collecting port 112, thereby achieving exhaust of the feed end 110. In some embodiments, an exhaust fan 530 can be provided in each gas collecting pipe 510 and the connecting pipe 540, and the exhaust of the exhaust fans 530 together can improve the exhaust efficiency.

[0060] refer to Figures 5 to 8 In some embodiments, the material distribution device 400 includes a fixed frame 410, a material distribution belt 420, and a swing mechanism 430. One end of the material distribution belt 420 is located outside the housing 100 and connected to the fixed frame 410 via a revolving joint. The other end of the material distribution belt 420 extends into the housing 100 through the feed inlet 111 and docks with the material receiving end 301. The structure of the material distribution belt 420 is not limited to a belt conveyor, a screw conveyor, a vibrating conveyor, etc. The belt of a belt conveyor can be a rubber belt or a metal mesh belt. Under the power of the swing mechanism 430, the material on the surface of the material distribution belt 420 is conveyed along the extension direction at a regulated speed into the housing 100. The swing mechanism 430 is connected to the material distribution belt 420 and is used to drive the material distribution belt 420 to rotate relative to the fixed frame 410 about the revolving joint, so that the end of the material distribution belt 420 located within the housing 100 swings back and forth. Therefore, the material distribution device 400 can swing the material, and the end of the material distribution belt 420 located inside the box body 100 can swing relative to the material receiving end 301 of the conveying device 300 to evenly distribute the material on the conveying mechanism. The reciprocating swinging can achieve a certain material thickness, which is beneficial for the material to evenly enter the box body 100 for solid-liquid separation, thereby improving the separation efficiency and effect.

[0061] A bearing 450 may be provided on the fixed frame 410, and the fabric belt 420 is connected to the bearing 450 via a rotating shaft 460 so that it can rotate around the axis of the rotating shaft 460. The rotating shaft 460 is radially limited to the inner ring of the bearing 450, serving as a fixed fulcrum 461 during the swinging process of the fabric belt 420, thereby forming a rotating pair connection between the fabric belt 420 and the fixed frame 410.

[0062] The swing mechanism 430 includes a driving part, which can be an electric, pneumatic or hydraulic power part. The driving part provides power output for the fabric belt 420 when swinging the fabric. The swing mechanism 430 also includes a transmission part, which is used to transmit the power of the power part. The driving part drives the fabric belt 420 to swing through the transmission part.

[0063] As an example, the transmission member may include a crank and a connecting rod connected by a revolute pair. The crank, the connecting rod, and the fabric belt 420 form a planar rocker mechanism, with the fabric belt 420 serving as the rocker arm. The connecting rod is connected to the end of the fabric belt 420 away from the rotating shaft 460 via a revolute pair. The driving member is connected to the end of the crank away from the connecting rod via a revolute pair. The driving member rotates the crank, thereby causing the fabric belt 420 to swing through the connecting rod. In another example, the transmission member may include a slider and a crank. The ends of the crank are respectively connected to the fabric belt 420 and the driving member via a revolute pair. The driving member may be a power member capable of outputting linear reciprocating motion, such as a linear slide or a telescopic cylinder. The slider, crank, and fabric belt 420 form a slider-crank mechanism, with the fabric belt 420 serving as the rocker arm. When the driver drives the slider to reciprocate linearly, the slider simultaneously drives the fabric belt 420 to swing back and forth through the crank.

[0064] refer to Figure 6 The material distribution device 400 may further include a feed hopper 440, which is located outside the housing 100, above the material distribution belt 420, and connected to the fixed frame 410 or the material distribution belt 420. The feed hopper 440 is used to receive wet materials manually fed or output from upstream equipment, and guide the wet materials onto the material distribution belt 420 to prevent the materials from being scattered outside the material distribution belt 420. The feed hopper 440 has a sloped inner wall, which facilitates the rapid discharge of materials and is less prone to material accumulation and blockage. The sloped inner wall can also be made into a smooth surface, such as the surface of a lens, to reduce friction, facilitate rapid material discharge, and thus ensure continuous feeding.

[0065] refer to Figure 5 The solid-liquid separation device of the embodiment of the present invention may also be connected to the feed port 111 with a seal 150. The seal 150 is located between the inner wall of the feed port 111 and the distribution device 400, and is used to block at least a portion of the feed port 111, thereby reducing the open area of ​​the feed port 111 and further reducing the probability of exhaust gas 240 from the interior of the housing 100 escaping. In some embodiments, the distribution device 400 can only use a linear conveying method to convey the wet material into the interior of the housing 100, and a gap may be provided between the seal 150 and the distribution device 400 to allow the material to enter. In the scheme where the distribution device 400 adopts a swing feeding method, the seal 150 can adopt a flexible and deformable structure. For example, the seal 150 can be a textile cloth, a rubber sheet, etc., which can adaptively deform with the swing of the distribution device 400 to avoid interference, while also effectively blocking the feed port 111.

[0066] refer to Figure 1In the solid-liquid separation device of the embodiment of the present invention, the conveying device 300 may include a plurality of layers of conveyor belts 310 spaced apart in the vertical direction. The conveyor belt 310 may be a metal conveyor belt 310, a plastic conveyor belt 310, or the like. The two ends of each conveyor belt 310 along the conveying direction are a head end and an end end, respectively. The head end of the conveyor belt 310 located on the uppermost layer is the material receiving end 301, and the end of the conveyor belt 310 located on the lowermost layer is the material unloading end 302. The conveying directions of adjacent conveyor belts 310 are opposite, and the head end of the conveyor belt 310 located on the lower layer is used to receive the material conveyed by the end of the conveyor belt 310 located on the upper layer. In this way, the material can be conveyed back and forth, and the conveying path of the material can be extended, thereby increasing the conveying time of the material in the box body 100, which is conducive to fully separating the moisture in the material and improving the separation effect. As an example, the conveying device 300 may include three layers of conveyor belts 310, namely, from top to bottom, an upper conveyor belt 311, a middle conveyor belt 312, and a lower conveyor belt 313. The middle conveyor belt 312 conveys materials in the opposite direction of the upper conveyor belt 311 and receives materials from the end of the upper conveyor belt 311. The lower conveyor belt 313 conveys materials in the same direction as the upper conveyor belt 311 and receives materials from the end of the middle conveyor belt 312. The multiple layers of conveyor belts 310 arranged in a vertical direction can effectively utilize vertical space, reduce the length of the box 100, and thus reduce the floor space. The conveying device 300 may include a frame for mounting the conveyor belts 310. Alternatively, the conveyor belt 310 can be mounted on the box 100 to ensure stable installation of the conveyor belt 310.

[0067] The conveying device 300 may also include a driven tensioning adjustment device 320 for adjusting the tension of the conveyor belt 310 during automatic circulation. The driven tensioning adjustment device 320 includes a standard tensioning belt seat bearing, a bolt, and a tensioning nut. The bolt connects the tensioning belt seat bearing to the housing 100 / frame, and the tensioning nut is connected to the bolt. The tension is adjusted by rotating the tensioning nut, preventing the conveyor belt 310 from loosening and affecting material transportation.

[0068] refer to Figure 1 In some embodiments, the conveying device 300 may further include a material guide 330. The material guide 330 is provided between adjacent conveyor belts 310. The material guide 330 is located above the head end of the lower conveyor belt 310 and is spaced apart from the end of the upper conveyor belt 310. The material guide 330 can provide guidance for the material in the process of circulating and descending from the end of the upper conveyor belt 311, so that the material falls onto the lower conveyor belt 313, and prevents the material from falling to other locations. The material guide 330 can be fixed to the frame of the conveying device 300 to achieve material guidance.

[0069] refer to Figure 1In some embodiments, the conveying device 300 further includes an ash hopper 340, which is located in the housing 100 and below the head end of the lowest conveyor belt 310. The ash hopper 340 has an upward opening and a downward waste outlet 341, and the waste outlet 341 is located outside the housing 100. The ash hopper 340 is used to collect solid waste such as dust generated during the circulation of materials on the conveyor belt 310. The dust can come from solid waste generated after moisture in the materials is separated, as well as residual dust generated during the long-term use of the conveying device 300. The dust is collected by the ash hopper 340 and discharged to the outside of the housing 100 through the waste outlet 341, which can effectively avoid the accumulation of waste at the bottom of the housing 100, thereby reducing maintenance frequency and saving maintenance costs, and also facilitating continuous production.

[0070] The discharge port 121 is provided below the end of the conveyor belt 310 at the lowest layer, and the material can fall from the end of the conveyor belt 310 to the discharge port 121, and thus be output to the outside of the box body 100. A discharge hopper 130 can be provided at the discharge port 121, and the discharge hopper 130 has an upward opening and a downward discharge port 131, and the discharge port 131 is located outside the box body 100. The discharge hopper 130 is used to receive the material falling from the end of the conveyor belt 310 at the lowest layer, and discharge it to the outside of the box body 100 through the discharge port 131. The discharge hopper 130 can have an inclined slope inner wall, which is conducive to the rapid discharge of the material and is not prone to material accumulation and blockage. The slope inner wall of the discharge hopper 130 can also be made into a smooth surface, such as the surface of a lens, which can reduce friction and is more conducive to rapid discharge, thereby ensuring continuous discharge.

[0071] In some embodiments, the solid-liquid separation device may further include a material receiving piece 600, which is arranged below the discharge port 121 and is used to receive the material output from the discharge port 121 or the discharge port 131 of the discharge hopper 130, or the material receiving piece 600 is used to install a packaging bag, which is used to receive the material output from the discharge port 121 or the discharge port 131 of the discharge hopper 130, thereby realizing the collection of materials after solid-liquid separation.

[0072] refer to Figure 1The solid-liquid separation device may also include a reminder device that switches to a reminder state when the material receiving reaches a set amount, prompting the user to replace the receiving unit 600 or the packaging bag. As an example, the reminder device may include a weighing scale 700, a reminder module communicatively connected to the weighing scale, and a reminder device. The reminder device may be a reminder light or a speaker. The reminder light may be illuminated or flashing, and the speaker may emit a beeping sound. The receiving unit 600 is placed on the weighing scale 700, which is preset to a weight value corresponding to the weight of the received material reaching the set amount. The reminder module is configured to switch the reminder device to a reminder state when the weighing scale 700 reaches the preset weight value. In other examples, a distance sensor may be used in place of the weighing scale 700. For example, a distance sensor may be installed above the receiving unit 600. The distance sensor is configured to change a sensing signal when the material receiving reaches a set pile height. The reminder module is configured to switch the reminder device to a reminder state based on the sensing signal from the distance sensor. This achieves automatic material receiving / packaging and automatic weighing functions, reducing manual labor.

[0073] refer to Figure 1 and Figure 9 In some embodiments, the solid-liquid separation device further includes an exhaust device 800, which includes an exhaust pipe 810 and an exhaust hood 820. The housing 100 is provided with an exhaust port connected to the interior. The exhaust hood 820 is connected to the discharge end 120 and connected to the interior of the discharge end 120. The exhaust pipe 810 connects the exhaust port and the exhaust hood 820. The exhaust gas generated inside the housing 100 can be discharged through the exhaust pipe 810. The exhaust hood 820 at the discharge end 120 can effectively prevent the exhaust gas inside the housing 100 and the dust-containing exhaust gas generated during the discharge process from being discharged into the external environment. The solid-liquid separation device further includes a dust removal device 830, which is connected to the exhaust pipe 810. The dust removal device 830 can pass the exhaust pipe 810 into the dust removal device 830 for treatment before being discharged. This prevents the sulfide gas and smoke exhaust gas 240 generated by the heating of the device and materials in the housing 100 from being discharged to the outside world without being treated and causing environmental impact.

[0074] refer to Figure 1 、 Figure 9 and Figure 10 The exhaust pipe 810 may include a main pipe 812 and multiple branch pipes 811. Multiple branch pipes 811 are arranged and connected in the section between the feed end 110 and the discharge end 120 of the housing 100. The exhaust hood 820 is also connected to a branch pipe 811. Each branch pipe 811 is connected to the main pipe 812 and connected to the dust removal device 830 through the main pipe 812. The main pipe 812 includes a reducer 813. The reducer 813 is located between the branch pipes 811 of the exhaust hood 820 and the branch pipes 811 connected to the housing 100. This can increase the cross-sectional area of ​​the main pipe 812 on the side of the branch pipes 811 connected to the housing 100, thereby increasing the exhaust volume.

[0075] refer to Figures 9 to 11 The temperature control device 200 may include a heat exchanger 220, which is connected to the dust removal device 830 and the box body 100 through a pipeline, and is used to recover the heat of the gas discharged by the dust removal device 830 and to exchange heat with the gas input into the box body 100. It can effectively recover the heat of the exhaust gas 240, realize energy recovery and reuse, reduce energy loss, and effectively reduce electricity consumption and operating costs.

[0076] In some embodiments, the temperature control device 200 includes a housing 210 and a heat exchanger 220. The housing 210 has a first inlet 211, a first outlet 212, a second inlet 213, and a second outlet 214. The heat exchanger 220 is located within the housing 210. The first inlet 211 is connected to the air outlet of the dust removal device 830 via a pipeline, and is used to introduce exhaust gas 240 discharged from the dust removal device 830 into the housing 210 for contact and heat exchange with the heat exchanger 220. The first outlet 212 is used to discharge the exhaust gas 240 introduced into the housing 210 via the first inlet 211. The second inlet 213 is used to introduce fresh air 230 (for input into the housing 100) into the heat exchanger 220, so that the fresh air 230 contacts and exchanges heat with the heat exchanger 220. The second outlet 214 is connected to the housing 100 via a pipeline, and is used to input the fresh air 230 after heat exchange into the housing 100.

[0077] During application, the exhaust gas 240 at the outlet of the dust removal device 830 can be introduced into the first inlet 211 through the centrifugal fan 840, and the fresh air 230 enters from the second inlet 213, forming an energy exchange with the return air drawn back from the centrifugal fan 840. After the recovered energy is recovered, the fresh air 230 is output from the second outlet 214 and enters the housing 100 through the air inlet 140 of the housing 100. After the energy exchange, the return air input from the centrifugal fan 840 into the housing 210 is discharged into the atmosphere from the first outlet 212 or enters the next stage of dust removal and filtration. The heat exchanger 220 provides energy recovery for the exhaust gas of the dust removal device 830 after centralized dust removal, realizes energy exchange for the incoming fresh air 230, and reduces the energy loss of the device. Similarly, the fresh air 230 can also be introduced into the housing 100 through the centrifugal fan 840, and the air volume can be adjusted according to the size of the production capacity to achieve energy saving.

[0078] refer to Figure 1 and Figure 9The air inlet 140 of the box body 100 can be located on the bottom wall of the box body 100 or at the bottom of the side wall of the box body 100, lower than the lowest conveyor belt 313 of the multi-layer conveyor belt 310. Multiple air inlets 140 can be arranged between the feed end 110 and the discharge end 120 of the box body 100, and fresh air 230 is introduced through a unified pipeline. The fresh air 230 with energy (the source of energy is not limited to hot air, steam, refrigerated air, etc.) is transported to the bottom air inlet 140 of the box body 100 after recovering the energy of the exhaust gas 240 through the heat exchanger 220. It passes from the bottom of the conveyor belt 310 to the top of the materials on each layer of the middle conveyor belt 310 and the upper conveyor belt 311. As the energy circulates through the materials on each layer, it continuously exchanges heat and cold with the materials, gradually removing moisture from the materials.

[0079] Dust removal device 830 may include a dust filter, centrifugal fan 840, duct 831, and a water curtain dust collector. Dust filters may include, but are not limited to, filter cartridges, bags, titanium rods, and plate filters. When centrifugal fan 840 is activated, a negative pressure is created within duct 831 of dust removal device 830 and the dust filter. Dust-laden exhaust gas 240 from the solid-liquid separation device is collected via main pipe 812 and branch pipe 811 and then fed into the dust filter. Differential pressure gauges are located before and after the filter element. If the dust filter surface becomes clogged with dust and the backlog is severe, the pressure resistance before and after the dust filter increases and reaches the differential pressure gauge's set limit, triggering an alarm in the control system to initiate automatic pulse dust removal. Clean exhaust gas after the filter returns to centrifugal fan 840. The clean exhaust gas from the centrifugal fan 840 exchanges energy with the fresh air 230 through the heat exchanger 220, and is then input into the water curtain dust collector at the end through the pipe connected to the first outlet 212 for further treatment to remove dust in the exhaust gas before being discharged.

[0080] In some embodiments, the gas collecting device 500 of the feed end 110 of the box body 100 is also connected to the exhaust pipe 810, so that the exhaust gas 240 in the feed end 110 is also sent into the dust removal device 830 through the exhaust pipe 810. Heat exchange through the heat exchanger 220 can effectively avoid energy loss caused by the opening of the feed port 111, which can effectively reduce the energy consumption of the device and save the operating cost of the equipment.

[0081] The solid-liquid separation device of the embodiment of the present utility model can be applied to the continuous solid-liquid separation of various wet materials. The following describes a specific application example of using the solid-liquid separation device of the embodiment of the present utility model to perform solid-liquid separation on graphite rod materials:

[0082] The graphite rod material is fed into the feeding hopper 440 and fed into the distributing device 400 . The distributing belt 420 is driven by the swing mechanism 430 to swing left and right with the rotating shaft 460 as the fulcrum, so that the graphite rod material is evenly distributed on the uppermost conveyor belt 310 (also referred to as the upper conveyor belt 311 ) of the conveying device 300 .

[0083] The upper conveyor belt 311 conveys graphite rod materials from the head end to the tail end, and the graphite rod materials fall from the tail end through the material guide 330 and freely fall onto the adjacent lower conveyor belt 310 (which may be called the middle conveyor belt 312);

[0084] The conveying direction of the middle conveyor belt 312 from the head end to the tail end is opposite to that of the upper conveyor belt 311. The middle conveyor belt 312 conveys the graphite rod material in the reverse direction from the head end to the tail end. The graphite rod material falls at the tail end of the middle conveyor belt 312 and freely falls to the adjacent lower conveyor belt 310 (which may be referred to as the lower conveyor belt 313) through the material guide 330.

[0085] The conveying direction of the lower conveyor belt 313 from the beginning to the end is opposite to that of the middle conveyor belt 312 and is the same as that of the upper conveyor belt 311. The lower conveyor belt 313 conveys graphite rod materials from the beginning to the end. The graphite rod materials fall at the end of the lower conveyor belt 313 and freely fall through the discharge hopper 130 into the packaging bag set on the receiving unit 600 for packaging. When the weighing device (weighing scale 700) reaches the preset weight, the prompt unit switches to the reminder state, automatically alarming the operator to manually unload the materials and change the bags.

[0086] The energy source is supplied by the fan, and the energy (the energy source is not limited to hot air, steam, refrigerated air, etc.) is delivered to the bottom air inlet 140 of the box body 100. The energy flows from the bottom to the top of the conveyor belt 310, passing through the graphite rod materials on each layer of the middle conveyor belt 312 and the upper conveyor belt 311. As the energy circulates through the graphite rod materials on each layer, it continuously exchanges heat with the graphite rod materials, gradually removing moisture from the graphite rod materials, and achieving solid-liquid separation of the graphite rod materials.

[0087] The wet air after exchanging with the material is collected by the air collecting hood 520, the exhaust hood 820 and the branch pipes 811, and then collected by the branch pipes 811 and sent to the centralized dust removal device 830 through the main pipe 812 for collection and dust removal.

[0088] The gas collecting device 500 exhausts gas through an internal exhaust fan 530 and is discharged through multiple gas collecting pipes 510, so that a negative pressure or a slightly negative pressure is formed at the feed inlet 111. This can effectively prevent the dust-containing exhaust gas and odor in the box 100 from leaking into the air, thereby avoiding pollution of the working environment.

[0089] When centrifugal fan 840 is turned on, dust removal device 830 creates a negative pressure in the pipe 831 of dust removal device 830 and the dust collector, collecting the dust-laden exhaust gas in box 100 through main pipe 812 and branch pipe 811 and entering the dust filter built into the dust collector (the types of filter devices include but are not limited to: filter element, cloth bag, titanium rod, plate filter, etc.). Differential pressure gauges are installed before and after the dust filter element. When the filter surface is blocked by dust and the backlog is severe, the pressure resistance before and after the filter increases and reaches the set value limit of the differential pressure gauge, the control system alarm is triggered to automatically perform pulse dust removal. The clean exhaust gas after passing through the filter returns to centrifugal fan 840 again;

[0090] The clean exhaust gas from the centrifugal fan 840 exchanges energy with the fresh air 230 through the heat exchanger 220, and then is input into the water curtain dust collector at the end for further treatment to remove dust in the exhaust gas before being discharged.

[0091] The solid-liquid separation device of the present application provides a safe, leak-free method for separating wet materials during continuous production, eliminating the need for intermittent shutdown of centrifuges for loading and unloading, and facilitating the continuous processing of large quantities of materials. Some embodiments of the solid-liquid separation device can also automatically bag materials using a material receiving unit 600 and a reminder device, reducing manual labor. Some embodiments of the solid-liquid separation device can recycle exhaust gas energy, saving energy costs.

[0092] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. In addition, the embodiments of the present invention and the features of the embodiments can be combined with each other unless there is a conflict.
