[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0037] like Figures 1 to 5 As shown, the solid separation system for slurry according to an embodiment of the present invention includes a solid separation device 10, a solid collection device 20 and a solid transfer device 30. The solid separation device 10 has a material chamber 101 and a feed port 102 connected to the material chamber 101. The feed port 102 is for the slurry to enter the material chamber 101. The cavity wall of the material chamber 101 is provided with a plurality of material holes for the slurry to flow out. The aperture of the material hole is less than or equal to a preset value to block foreign particles. The solid collection device 20 has a collection chamber 201, and the collection chamber 201 is used to collect foreign particles. The solid transfer device 30 is used to transfer the solid separation device 10 to the solid collection device 20 to transfer the foreign particles into the collection chamber 201. The foreign particles can be understood as solid particles with a particle size greater than or equal to a preset value. The preset value is determined according to the type of slurry and the particle size requirements for the solid particles in the slurry.
[0038] like Figures 1 to 4As shown, the solid separation system for slurry according to an embodiment of the present invention is placed in the notch of the trough 50 for use. In specific use, the slurry enters the material chamber 101 through the feed port 102 of the solid separation device 10. Fixed particles with a particle size greater than or equal to the preset value are intercepted in the material chamber 101 because they cannot pass through the material hole. Slurry with a particle size less than the preset value flows out into the trough 50 through the material hole, so as to intercept impurity particles with a particle size greater than or equal to the preset value in the solid separation device 10, thereby preventing impurity particles with a particle size greater than or equal to the preset value from entering the trough 50. When it is necessary to clean the impurity particles in the solid separation device 10, the solid transfer device 30 is used to transfer the solid separation device 10 to the solid collection device 20. The impurity particles are then collected by the collection chamber 201 of the solid collection device 20, thereby cleaning the impurity particles in the solid separation device 10. As a result, the separation and cleaning costs of impurity particles in the slurry are reduced, and the cleaning efficiency of impurity particles in the slurry is improved.
[0039] In some embodiments, as Figure 5 、 Figure 6 、 Figure 8 and Figure 9 As shown, solid separation device 10 includes a housing 106 and an upper cover 107. Housing 106 has an opening, and a feed port is provided on housing 106. Upper cover 107 is connected to housing 106 and is used to open or close the opening. Upper cover 107 and housing 106 define a feed chamber 101, and feed port 102 is provided on upper cover 107.
[0040] When using the solid separation device 10 to separate foreign particles, the opening is closed to prevent the slurry or foreign particles from flowing out of the opening; when cleaning the foreign particles in the solid separation device 10, the opening is opened so that the foreign particles can be discharged from the material cavity 101.
[0041] By configuring the solid separation device 10 to include a housing 106 and an upper cover 107, with the housing 106 and the upper cover 107 connected to form a material chamber 101, it is possible to effectively prevent the slurry from not passing through the material holes or foreign particles within the material chamber 101 from flowing out, thereby preventing the foreign particles from entering the material trough 50 and affecting product quality. This improves the reliability of the solid separation device 10, thereby improving the reliability of the solid separation system for slurry.
[0042] Alternatively, as Figure 5 and Figure 6 As shown, the solid separation device 10 further includes a driving device 108, which is used to drive the upper cover 107 to move so as to open or close the opening.
[0043] The upper cover 107 is hinged to the shell 106 , and the driving device 108 can be a damping spring or a driving motor. The driving device 108 is used to drive the upper cover 107 to rotate relative to the shell 106 to open or close the opening.
[0044] By providing the driving device 108, the opening can be automatically opened or closed, thereby further improving the cleaning efficiency of the foreign particles in the slurry.
[0045] Alternatively, as Figure 5 and Figure 6 As shown, the upper cover 107 is provided with an upper cover handle 1071 .
[0046] By providing an upper cover handle 1071 on the upper cover 107 , when the upper cover 107 needs to be moved or operated, the upper cover handle 1071 can be manually grasped to facilitate moving the upper cover 1071 , for example, manually opening or closing the upper cover 107 .
[0047] Alternatively, as Figure 5 As shown, the upper cover 107 has an observation window 103 .
[0048] The observation window 103 may be made of a transparent material, such as a glass plate or an acrylic plate.
[0049] By providing an observation window 103 on the upper cover 107, the situation in the material cavity 101, such as the amount of impurity particles, can be observed through the observation window 103. This facilitates timely processing of the solid separation device 10 and improves the reliability of the solid separation system for slurry.
[0050] Alternatively, as Figure 5 and Figure 7 As shown, the upper cover 107 has a cleaning port 104 , and the cleaning port 104 is used to install a cleaning pipe 110 .
[0051] For example, Figure 7 As shown, the cleaning pipe 110 is provided with a cleaning nozzle 1101 , and the cleaning nozzle 1101 is used to spray cleaning liquid (such as water) onto the cavity wall of the material cavity 101 to clean the material cavity 101 .
[0052] By providing a cleaning port 104 on the upper cover 107, when the material chamber 101 needs to be cleaned, a cleaning pipe 110 can be installed in the cleaning port 104 to clean the material chamber 101, for example, to clean foreign particles or adhered slurry on the material holes, thereby preventing the material chamber 101 from being blocked. This improves the working efficiency of the solid separation system for slurry.
[0053] Alternatively, as Figure 5 As shown, the upper cover 107 has an instrument opening 105 for installing an instrument.
[0054] For example, the instrument port 105 is used to install a liquid level detection device.
[0055] By installing an instrument at the instrument port 105, the situation inside the material chamber 101 can be detected, for example, the liquid level of impurity particles in the material chamber 101 can be detected, so as to judge the situation inside the material chamber 101, facilitate timely corresponding processing of the solid separation device 10, and improve the reliability of the solid separation system for slurry.
[0056] In specific use, the instrument can be connected to a control system. The control system determines whether the solid separation device 10 needs to be processed accordingly based on the data detected by the instrument and issues corresponding instructions. For example, the control system determines whether the solid separation device 10 needs to be cleaned of foreign particles based on the data detected by the liquid level detection device. If the foreign particles need to be cleaned, the control system issues an instruction to the solid transfer device 30 to control the fixed transfer device 30 to transfer the solid separation device 10 to the solid collection device 20.
[0057] Alternatively, as Figure 8 and Figure 9 As shown, the shell 106 includes a frame 1061 , a screen 1062 and reinforcing ribs 1063 . The screen 1062 is connected to the frame 1061 , the reinforcing ribs 1063 are connected to the screen 1062 , and the material holes are set on the screen 1062 .
[0058] Frame 1061 may be a basket-type frame, with screen 1062 secured to the outside of frame 1061. Frame 1061 supports screen 1062. Ribs 1063 are secured to the outside of screen 1062 to enhance its mechanical strength. The materials of frame 1061, screen 1062, and ribs 1063 are selected based on the slurry's material and should avoid reacting with it. For example, frame 1061, screen 1062, and ribs 1063 may be made of materials with excellent mechanical properties and corrosion resistance, such as 304, 316L, or 2205 duplex steel.
[0059] By configuring the shell 106 to include the frame 1061 , the screen 1062 and the reinforcement ribs 1063 , the cost of the shell 106 can be reduced while ensuring the structural strength of the shell 106 , thereby reducing the cost of the solid separation system for slurry.
[0060] Optionally, the frame 1061 is a rectangular frame, and the lower surface and four side surfaces of the screen 1062 are connected with reinforcing ribs 1063 .
[0061] In other embodiments, the housing 106 may also be formed by welding metal plates, and holes are provided in the metal plates. That is, the housing 106 is made of metal plates with holes. For example, the housing 106 is formed by welding perforated steel plates.
[0062] Alternatively, as Figure 9 As shown, an overflow port 1064 is provided on the upper portion of the frame 1061 for the slurry to flow out.
[0063] By setting an overflow port 1064 at the upper part of the frame 1061, when the slurry in the material chamber 101 exceeds the preset height, it can flow out through the overflow port 1064, thereby preventing the slurry in the material chamber 101 from exceeding the preset height and improving the reliability of the solid separation system for the slurry.
[0064] Alternatively, as Figure 8 and Figure 9 As shown, the housing 106 includes a support plate 1066, which is connected to the upper portion of the frame 1061 and is used to support the housing 106. The support plate 1066 can be a steel plate.
[0065] For example, Figure 1 As shown, a support frame 40 is provided at the notch of the trough 50, and a support plate 1066 is placed on the support frame 40 to support the solid separation device 10 using the support frame 40. The support plate 1066 is placed on the support frame 40 to support the solid separation device 10.
[0066] like Figure 5 and Figure 8 As shown, the support plate 1066 is provided with a connection hole 1067, and the upper cover 107 includes a cover plate 1072. The feed port 102, the observation window 103, the cleaning port 104, and the instrument port 105 are all provided on the cover plate 1072. The cover plate 1072 is provided with a fastening hole 109, which is provided corresponding to the connection hole 1067. The fastener passes through the fixing hole 109 and the connection hole 1067 to achieve a fixed connection between the upper cover 107 and the housing 106.
[0067] Alternatively, as Figure 3 and Figure 8 As shown, the housing 106 is provided with a housing handle 1065 .
[0068] By providing a housing handle 1065 on the housing 16, when the housing 106 needs to be moved, the housing handle 1065 can be connected manually or with a sling to facilitate the movement of the housing 106. For example, the housing handle 1065 is connected to the solid transport device 30 to achieve the movement of the solid separation device 10.
[0069] In some embodiments, as Figure 3 and Figure 4As shown, the solid collecting device 20 includes a transfer bin 202 and a hopper 203. The hopper 203 is arranged on the upper side of the transfer bin 202. The collecting chamber 201 is arranged on the transfer bin 202. The outlet of the hopper 203 is arranged corresponding to the inlet of the transfer bin 202.
[0070] The solids transfer device 30 transfers the solids separation device 10 to the solids collection device 20, where the impurities are poured into the hopper 203. The hopper 203 then guides the impurities into the collection chamber 201 of the solids collection device 20. This creates a height difference between the collection chamber 201 and the solids separation device 10, facilitating the transfer of impurities within the collection chamber 201. For example, the impurities within the collection chamber 201 can be transported to a subsequent processing step by vehicle.
[0071] Alternatively, as Figure 4 As shown, the solid collecting device 20 further includes a pouring plate 204 . The pouring plate 204 is disposed at the inlet of the hopper 203 , and the pouring plate 204 gradually decreases in a direction approaching the hopper 203 .
[0072] For example, Figure 4 As shown, the pouring plate 204 is disposed at the front side of the hopper 203. The pouring plate 204 gradually tilts downward from the back to the front. Therefore, when the solid separation device 10 is placed on the pouring plate 204, the opening of the housing 106 automatically tilts forward, thereby pouring the foreign particles in the housing 106 into the hopper 203.
[0073] By setting the pouring plate 204, the solid separation device 10 can be automatically tilted to automatically pour the impurity particles in the material chamber 101 into the hopper 203. Not only does it not require additional power, but it also facilitates the transfer of impurity particles in the material chamber 101 to the collection chamber 201.
[0074] Alternatively, as Figure 4 As shown, the solid collecting device 20 further includes a hopper baffle 205, which is disposed at the inlet of the hopper 203. The hopper baffle 205 and the pouring plate 204 are disposed on opposite sides of the hopper 203.
[0075] For example, Figure 4 As shown, the hopper baffle 205 is disposed at the front side of the hopper 203, and the pouring plate 204 is disposed at the rear side of the hopper 203. The solid separation device 10 pours foreign particles into the hopper 203 in a forward direction. During the pouring process, foreign particles that flow to the front side of the hopper 203 are blocked by the hopper baffle 205 and enter the hopper 203.
[0076] By providing the hopper baffle 205 , it is possible to prevent foreign particles from flowing out of the hopper 203 , further facilitating the recovery of foreign particles.
[0077] In some embodiments, as Figure 1 and Figure 3 As shown, the solid transport device 30 includes a lifting device 301 and a translation device 302. The lifting device 301 is used to drive the solid separation device 10 to move in the up and down directions, and the translation device 302 is used to drive the solid separation device 10 to move in the horizontal direction.
[0078] When the solid separation device 10 is transferred to the solid collection device 20, the solid separation device 10 is first lifted up to a certain height using the lifting device 301, and then the solid separation device 10 is translated forward to the pouring plate 204 using the translation device 302, and the solid separation device 10 is placed on the pouring plate 204. After that, the solid separation device 10 is automatically tilted on the pouring plate 204 to pour the impurity particles in the material cavity 101 into the hopper 203.
[0079] By configuring the solid transport device 30 to include a lifting device 301 and a translation device 302 , it is convenient to transport the solid separation device 10 to the solid collection device 20 .
[0080] Alternatively, as Figure 3 As shown, the solids transfer device 30 includes a bracket 305, and the lifting device 301 includes a fixed pulley 3011, a lifting rope 3012, and a lifting motor 3013. The fixed pulley 3011 is rotatably fixed to the bracket 305, the lifting rope 3012 is wound around the fixed pulley 3011, and the lifting motor 3013 is fixed to the bracket 305. One end of the lifting rope 3012 is provided with a connecting portion 3014, which is used to connect to the housing handle 1065. The other end of the lifting rope 3012 is connected to the lifting motor 3013. The lifting motor 3013 drives the lifting rope 3012 to extend and retract, thereby achieving the raising and lowering of the solids separation device 10. The lifting motor 3013 is provided with a take-up wheel, which drives the take-up wheel to rotate, thereby achieving the extension and retraction of the lifting rope 3012.
[0081] For example, two solid transporting devices 30 are provided, and are respectively provided on the left and right sides of the solid separation device 10 .
[0082] Alternatively, as Figure 3 As shown, the translation device 302 includes a guide rail 303, and the lifting device 301 is movable along the horizontal direction and guided by the guide rail 303.
[0083] By providing the guide rail 303 , the lifting device 301 cooperates with the guide rail 303 to prevent the lifting device 301 from deflecting when moving in the horizontal direction, which is beneficial to improving the reliability of the solid separation system for slurry.
[0084] like Figure 3As shown, the solid transport device 30 includes a roller 304, the translation device 302 includes a translation motor 3021, the roller 305 is rotatably mounted on the lower end of the bracket 305, the roller 305 is guided and matched with the guide rail 303, and the translation motor 3021 is used to drive the roller 305 to rotate.
[0085] like Figures 1 to 4 As shown, the slurry stirring system of an embodiment of the present invention includes a material trough 50 and a solid separation system for slurry. The solid separation system for slurry is the solid separation system for slurry described in any of the above embodiments, and the solid separation system for slurry is arranged at the notch of the material trough 50.
[0086] In some embodiments, the number of solid separation system arrangements for the slurry is at least two.
[0087] For example, two solid separation systems are provided for the slurry, wherein when one solid separation system for the slurry is in operation, the other solid separation system for the slurry is in a standby state, thereby achieving continuous feeding of the material tank 50 .
[0088] Optionally, the slurry stirring system includes a slurry pipe for connecting to the feed port 102 , and at least one section of the slurry pipe is detachably connected to the feed port 102 .
[0089] For example, the slurry pipeline is connected to the feed port 102 via a flange.
[0090] When the impurity particles in the solid separation device 10 need to be cleaned, the slurry pipeline is separated from the feed port 102 to separate the slurry pipeline from the solid separation device 10 and prevent the slurry pipeline from moving with the solid separation device 10 .
[0091] During the process of neutralizing acidic slurry with lime milk, it's necessary to prevent large particles from entering the slurry treatment tank. To address this issue, a solids separation system for the slurry can be installed at the tank's notch. The solids separation device 10 is constructed of 316L stainless steel to withstand corrosion from splashing acidic slurry within the tank. Two lime milk pipelines are used, corresponding to two solids separation systems for the slurry: one backup and one operational.
[0092] After one of the slurry-related solids separation systems has been running continuously for a period of time, the liquid level detection device detects that impurity particles in the material chamber 101 have reached a preset height. This determines that the slurry-related solids separation system needs to be cleaned. The system then interlocks with the automatic valve in the inlet pipe and switches to the other slurry-related solids separation system. Simultaneously, the slurry-related solids separation system in need of cleaning is manually disconnected from the lime milk pipeline. The collected limestone slag is then transferred to the transfer bin 202 for recycling via remote control of the solids transfer device 30.
[0093] The solids separation system for slurries effectively intercepts large particles in lime milk, ensuring that only appropriately sized particles pass through. This prevents clogging and potential damage to mixing equipment, thereby improving the efficiency and reliability of the neutralization process. The installation of this solids separation system for slurries streamlines the processing process, reduces maintenance requirements, and ensures consistent slurry quality. This innovation not only improves operational performance but also enhances the overall effectiveness of acid neutralization during mineral processing.
[0094] During the flocculant dilution process, it is necessary to prevent large particles in the raw materials from entering the preparation tank. To address this issue, a solid separation system for the slurry can be installed at the notch of the preparation tank. The solid separation device 10 is made of 304 stainless steel to withstand corrosion from chemical splashes in the preparation tank.
[0095] After one of the solid separation systems for slurry has been operating for a period of time, the liquid level detection device detects that the impurity particles in the material chamber 101 have reached a preset height, and determines that the solid separation system for slurry needs to be cleaned. The operation is switched to the other solid separation system for slurry. At the same time, the solid separation system for slurry that needs to be cleaned is cleaned.
[0096] After cleaning, the solid separation system for the slurry is reinstalled and covered with the upper cover 107. The solid separation device 10 is rinsed using the cleaning port 104 of the upper cover 107 to ensure that the fine particles adhering to it are completely removed. After reinstalling the feed pipe, the equipment continues to operate.
[0097] The solids separation system for slurries effectively intercepts large particles in the flocculant feedstock, ensuring that only particles of the appropriate size pass through.
