Description

Technical Field

[0001] The present invention relates to the field of separation, and particularly to a sedimentation separation device for the production of light calcium carbonate. Background Art

[0002] Light calcium carbonate, also known as precipitated calcium carbonate, is an important inorganic chemical product and is widely used in industries such as plastics, rubber, papermaking, and coatings. In the production process of light calcium carbonate, it is usually necessary to separate light calcium carbonate particles from the mother liquor through sedimentation separation. Traditional methods include using gravity sedimentation barrels or centrifugal separators, but these devices generally have the problems of low efficiency and limited processing capacity. Especially when dealing with a large amount of materials, traditional devices often lead to a decrease in production efficiency and affect the production process.

[0003] With the development of technology, technicians in related fields have also carried out a lot of optimization on the separation devices for the production of light calcium carbonate. For more accurate comparison, a Chinese patent with the publication number CN216855773U discloses an automatic separation device for light calcium carbonate slurry, including a separation box, a box cover, a single-chip microcomputer, a depth measurement mechanism, a cover, etc.; when in use, the depth of the clear liquid layer is detected by the depth measurement mechanism, and the single-chip microcomputer controls the telescopic movement of the electric telescopic mechanism based on the data measured by the depth measurement mechanism, thereby controlling the height of the cover and the water absorption layer to ensure that the water absorption layer can be moved to the junction of the clear liquid layer and the precipitation layer, so as to completely pump away the clear liquid layer. At the same time, under the conveying action of the water pump, the clear liquid layer is pumped out of the separation box through the liquid extraction branch pipe and the liquid extraction main pipe, thereby realizing the separation of the clear liquid layer and the precipitation layer. The automatic precise adjustment is adopted, and the separation is more thorough and the separation effect is better.

[0004] However, there are still some deficiencies in the above separation device during actual use: 1. During the use of the above device, it is always necessary to first detect the depth of the clear liquid layer through the depth measurement mechanism, then output the data to the single-chip microcomputer, control the cover and the water absorption layer thereon to move to the junction of the clear liquid layer and the precipitation layer, and then pump the water absorption layer and the clear liquid in the clear liquid layer through the water pump, the liquid extraction branch pipe and the liquid extraction main pipe, thereby realizing the separation of the clear liquid layer and the precipitation layer. However, the above device uses a sponge material as the water absorption layer. After placing it at the junction of the clear liquid layer and the precipitation layer and then starting the water pump, it is easy for the water pump to suck the precipitated matter in the precipitation layer to the outside of the water absorption layer when sucking the liquid extraction branch pipe and the liquid extraction main pipe, resulting in blockage on the outer side of the sponge and affecting the efficiency of subsequent extraction and separation. At the same time, if the suspended matter in the liquid layer adhered to the outer side of the sponge is not cleaned in time, it will also affect the service life of the sponge of the water absorption layer.

[0005] 2. After the above device injects the mother liquor containing light calcium carbonate particles into the box body, only by the gravity of the light calcium carbonate particles themselves, they naturally settle and separate in the mother liquor. It takes a long time for the particles in the mother liquor to naturally settle, with low efficiency and limited processing capacity.

[0006] Therefore, under the viewpoints stated above, there is still room for improvement in the existing technical means for separating light calcium carbonate. Summary of the Invention

[0007] To solve the above problems, the present invention provides a sedimentation and separation device for the production of light calcium carbonate, including a box body. The interior of the box body is hollow and connected to a water inlet channel. Inside the box body, there is also a separation component connected for separating the calcium carbonate-containing mixed liquid introduced into the box body. The separation component includes: An installation column, which is limitedly inserted through the box body corresponding to the water inlet channel and extends upward from the bottom of the box body into the box body. The upper end of the installation column is connected with an overflow tray, and a guiding arc plate is limitedly connected to the box body corresponding to the overflow tray.

[0008] A water delivery pipe, which is limitedly inserted through the installation column and connected to the water inlet channel correspondingly. Its two ends respectively penetrate through the overflow tray and the box body and are arranged.

[0009] A separation partition block, which is limited in the box body and is located below the overflow tray and penetrated by the installation column. A number of guiding channels are uniformly formed on it.

[0010] Preferably, the inclination angles of a number of the guiding channels are set.

[0011] Preferably, the overflow tray is arc-shaped and is arranged in an open-mouth shape.

[0012] Preferably, the side of the guiding arc plate away from the overflow tray is limitedly connected to the box body through a connecting guide rod.

[0013] Preferably, the separation component further includes a connecting through pipe limitedly inserted on the installation column. A guiding pipe penetrating through the installation column is connected to the connecting through pipe. The guiding pipe is located between the floating block and the overflow tray.

[0014] Preferably, the section of the guiding pipe away from the connecting through pipe is arranged in a bent shape.

[0015] Preferably, the separation partition block includes a floating block and a filtering block slidably sleeved on the installation column. A limiting ring plate is also connected to the box body corresponding to the floating block and the filtering block to limit the sliding range of the floating block and the filtering block. A number of guiding channels are opened on the floating block and the filtering block and are correspondingly communicated.

[0016] Preferably, the guiding pipe is arranged in a telescopic pipe structure.

[0017] Preferably, the diameter of the floating block is larger than that of the filter block and abuts against the inner wall of the box body. The limiting ring plate is attached to the lower end of the floating block, and a gap is provided between the outer edge of the filter block and the inner wall of the box body.

[0018] Preferably, a filter sheet is connected to one end of the guiding pipe away from the connecting pipe.

[0019] In summary, the present application includes at least one of the following beneficial technical effects: First, through the cooperation of the guiding arc plate and the overflow tray, the present invention avoids the turbulence caused by the rapid inflow of the mixed liquid, prolongs the sedimentation time of the light calcium carbonate particles, increases the effective sedimentation area of the particles through the inclined guiding channels on the separation partition block, reduces the sedimentation resistance, and improves the sedimentation efficiency. At the same time, the separation partition block blocks the disturbance of the water flow falling from the overflow tray and the guiding arc plate to the sedimentation area, preventing the deposited light calcium carbonate particles from being stirred up again, and greatly increasing the efficiency and effect of sedimentation separation of the light calcium carbonate particles in the mixed liquid.

[0020] Second, through the mutual cooperation of the guiding pipe and the connecting pipe, the present invention realizes the automatic intermittent discharge of the upper suspended clear liquid in the mixed liquid without manual intervention, effectively saving the equipment cost, and delays the discharge time of the suspended clear liquid through the bent guiding pipe structure to ensure the full sedimentation of the light calcium carbonate particles.

[0021] Third, through the cooperation of the floating block and the filter block with the limiting ring plate, the present invention dynamically adjusts the size of the sedimentation area to adapt to mixed liquids with different concentrations, improves the separation effect, and at the same time drives the dynamic position adjustment of the guiding pipe through the floating of the floating block and the filter block to ensure that the guiding pipe and the connecting pipe always guide and discharge the upper suspended clear liquid.

Specific embodiments

[0032] The following combines the attached Figure 1 to the attached Figure 8 The embodiments of the present invention will be described in detail.

[0033] The embodiment of the present application discloses a sedimentation and separation device for producing light calcium carbonate. The present application is mainly applied in the process of producing and preparing light calcium carbonate, and achieves the effect of sedimenting and separating light calcium carbonate in the mixed solution containing light calcium carbonate in terms of technical effects; especially in the process of sedimentation and separation, through the cooperation between the water delivery pipe, the guiding arc plate and the overflow tray, the disturbance of the sedimentation of light calcium carbonate particles in the mixed solution caused by turbulence during injection is effectively avoided; further, the device also realizes the dynamic guiding of the mixed solution in the box body through the mutual cooperation between the separation partition block and the guiding tube, promotes the rapid sedimentation of the particles therein, and automatically discharges the upper suspended clear liquid therein.

[0034] Embodiment 1: Refer to Figure 1 and Figure 2 As shown, a sedimentation and separation device for producing light calcium carbonate includes a box body 1. The inside of the box body 1 is hollow and connected with a water inlet channel 10. A separation component 2 for separating the calcium carbonate-containing mixed solution introduced into the box body 1 is also connected inside the box body 1. During use, after the light calcium carbonate-containing mixed solution (hereinafter simply referred to as "mixed solution") is introduced into the box body 1 through the water inlet channel 10, through the separation treatment of the separation component 2 inside the box body 1, the light calcium carbonate and the aqueous solution in the mixed solution are separated, and the light calcium carbonate settles to the bottom of the box body 1, achieving the effect of sedimentation and separation treatment of the light calcium carbonate in the mixed solution.

[0035] Refer to Figures 2 to 4 As shown, that is, the separation component 2 for separating the calcium carbonate-containing mixed solution introduced into the box body 1; specifically, the separation component 2 includes: The installation column 20 is limited and inserted through the box body 1 corresponding to the water inlet channel 10 and extends upward from the bottom of the box body 1 into the box body 1. An overflow tray 21 is connected to the upper end of the installation column 20. A guiding arc plate 22 is limited and connected in the box body 1 corresponding to the overflow tray 21. The guiding arc plate 22 and the overflow tray 21 are arranged at intervals.

[0036] The water delivery pipe 23 is limited and inserted through the installation column 20 and is correspondingly connected and communicated with the water inlet channel 10. Its two ends respectively penetrate out of the overflow tray 21 and the box body 1.

[0037] The separation partition block 24 is limited in the box body 1 and is located under the overflow tray 21 and is penetrated by the installation column 20. A plurality of guiding channels 240 are uniformly formed thereon. The separation partition block 24 and the inner bottom wall of the box body 1 are arranged at intervals to form a sedimentation interval 25.

[0038] During use, after the mixed liquid is input into the box body 1 from top to bottom through the water delivery pipe 23, the input mixed liquid will first impact on the guiding arc plate 22 and then fall into the overflow tray 21. After the overflow tray 21 is filled with the mixed liquid, the subsequent mixed liquid falling to the overflow tray 21 will automatically overflow from the overflow tray 21 and fall to the separation partition block 24, and then move down through the plurality of guiding channels 240 on the separation partition block 24 to be stored at the bottom of the box body 1. After the sedimentation interval 25 is filled with the mixed liquid, due to the density difference between the light calcium carbonate and the aqueous solution (usually the density of the light calcium carbonate is greater than that of the aqueous solution), the light calcium carbonate in the mixed liquid will be continuously deposited in the sedimentation interval 25 at the bottom of the box body 1, achieving the effect of sedimentation separation treatment of the light calcium carbonate in the mixed liquid.

[0039] Through the mutual cooperation among the water delivery pipe 23, the guiding arc plate 22 and the overflow tray 21, the path of the mixed liquid introduced into the box body 1 is guided and limited, effectively avoiding the problem that after the rate of inputting the mixed liquid into the box body 1 is relatively fast, a turbulent flow with a relatively fast flow rate is formed in the box body 1, increasing the sedimentation time of the light calcium carbonate particles in the mixed liquid. At the same time, through the blocking of the set separation partition block 24, the problem that the water flow falling from the overflow tray 21 and the guiding arc plate 22 causes great disturbance to the sediment after sedimentation at the sedimentation interval 25 is avoided.

[0040] It should be noted that in order to take out the sediment after sedimentation separation in the box body 1, a discharge pipe (not shown in the figure) communicating with the sedimentation interval 25 is further provided on the lower side of the box body 1. The discharge pipe (not shown in the figure) is connected to an external extraction pump (not shown in the figure) to pump out the sedimented calcium carbonate for further processing.

[0041] It should be noted that the extraction pump (not shown in the figure) adopts a conventional existing sludge pump for extracting sediments and will not be elaborated here.

[0042] Furthermore, referring to Figures 3 to 5 As shown, in order to improve the sedimentation efficiency of light calcium carbonate in the mixed liquid, the inclination angles of several guiding channels 240 are set. During use, the light calcium carbonate particles are naturally sedimented under the action of their own gravity in the mixed liquid. During the process of entering the sedimentation interval 25 through the inclined guiding channels 240, the inclined guiding channels 240 can change the sedimentation path of the light calcium carbonate particles, increase the effective sedimentation area of the particles, reduce the resistance suffered by the particles during sedimentation, thereby accelerating the sedimentation speed and enabling them to sediment more quickly and effectively under the action of gravity.

[0043] As the light calcium carbonate in the mixed liquid is sedimented and separated, the mixed liquid in the box body 1 gradually forms a layer structure of an upper suspended clear liquid (mainly aqueous solution) and a lower sediment (mainly sedimented light calcium carbonate).

[0044] At the same time, due to the continuous input of the mixed liquid in the box body 1, the liquid level of the mixed liquid in the box body 1 will continuously rise, causing the upper suspended clear liquid to continuously move upward to the upper side of the separation partition 24 through several guiding channels 240 on the separation partition 24, while the lower sediment will be blocked by the inclined guiding channels 240 and the separation partition 24 and is difficult to move upward by itself.

[0045] Referring to Figures 2 to 4 As shown, the overflow tray 21 is arc-shaped and open, and the guiding arc plate 22 is also set to be arc-shaped corresponding to the overflow tray 21. During use, the impact force of the mixed liquid input through the water delivery pipe 23 and impacting on the guiding arc plate 22 is effectively weakened after contacting the arc surface of the guiding arc plate 22. At the same time, the mixed liquid impacting on the arc surface of the guiding arc plate 22 will form a water film along its arc surface to guide the subsequent injected mixed liquid to impact on the guiding arc plate 22 and then fall into the overflow tray 21 and the box body 1.

[0046] Referring to Figures 2 to 4 As shown, one side of the guiding arc plate 22 away from the overflow tray 21 is connected to the box body 1 in a limited position through a connecting guide rod 220 for limiting and connecting the guiding arc plate 22.

[0047] Furthermore, referring to Figures 2 to 4As shown in the figure, during the continuous injection of the mixed liquid into the box body 1, the overall liquid level of the mixed liquid in the box body 1 will continuously rise. Therefore, in order to avoid the problem that the continuous accumulation of the mixed liquid in the box body 1 affects the subsequent sedimentation separation effect of light calcium carbonate, the separation assembly 2 further includes a connecting through pipe 26 inserted and limited on the mounting column 20. A guiding pipe 260 passing through the mounting column 20 is communicated with the connecting through pipe 26. One end of the connecting through pipe 26 far from the guiding pipe 260 passes through the mounting column 20, and the guiding pipe 260 is located between the floating block 241 and the overflow tray 21. During use, the supernatant liquid on the upper layer of the mixed liquid will move up synchronously with the rise of the mixed liquid in the box body 1 and cross the guiding pipe 260, so that the guiding pipe 260 and the connecting through pipe 26 are communicated with the upper supernatant liquid layer, thereby guiding and discharging the upper supernatant liquid out of the box body 1.

[0048] In order to increase the rate of guiding and discharging the supernatant liquid, as an optional implementation manner, a plurality of connecting through pipes 26 and guiding pipes 260 are circumferentially arranged corresponding to each other with the mounting column 20 as the axis.

[0049] Furthermore, referring to Figures 3 to 6 As shown in the figure, in order to avoid the problem that when the mixed liquid in the box body 1 crosses its own position, the guiding pipe 260 prematurely guides and discharges the mixed liquid (that is, when the liquid level of the mixed liquid just crosses the guiding pipe 260, the light calcium carbonate particles suspended in the solution have not been completely sedimented), resulting in the need for subsequent treatment by the staff, a section of the guiding pipe 260 far from the connecting through pipe 26 is arranged in an approximately "S"-shaped bent shape. During use, after the supernatant liquid enters the guiding pipe 260, due to the "S"-shaped structure of the guiding pipe 260, there is a height difference (liquid level difference) between its two bent sections. When the liquid level of the mixed liquid just crosses one of the bent sections of the guiding pipe 260, a part of the upper supernatant liquid therein will enter the bent section of the guiding pipe 260. At this time, the mixed liquid itself alone is not sufficient to drive the supernatant liquid entering the bent section of the guiding pipe 260 to pass through the height difference between the two bent sections, thereby achieving the effect of delaying the guiding and discharging of the mixed liquid.

[0050] When the mixed liquid accumulates to a certain position in the box body 1 (at least crossing the overall height of the guiding pipe 260), under the influence of its own gravity and the push of atmospheric pressure, the mixed liquid crossing the guiding pipe 260 drives the supernatant liquid entering the guiding pipe 260 to continue to pass through the guiding pipe 260 and then enter the connected connecting through pipe 26, so that the supernatant liquid fills the inside of the guiding pipe 260 and the connecting through pipe 26, squeezes out the gas inside the pipeline, and then discharges downward out of the box body 1 along the connecting through pipe 26. Until the liquid level of the mixed liquid in the box body 1 drops to the bent section, the discharge of the supernatant liquid stops. After the liquid level of the mixed liquid in the box body 1 crosses the overall height of the guiding pipe 260 again, the supernatant liquid is continuously guided and discharged. In this way, the automatic extraction effect of the upper supernatant liquid in the box body 1 is realized.

[0051] Referring to Figure 4 as shown, referring to Figures 3 to 5 as shown, the separation partition block 24 includes a floating block 241 and a filter block 242 that are slidably sleeved on the mounting post 20. A limiting ring plate 243 is also connected inside the box body 1 corresponding to the floating block 241 and the filter block 242. Through the limitation of the floating block 241 and the filter block 242 by the limiting ring plate 243, there is always a certain empty space (i.e., the sedimentation interval 25) between the bottom of the filter block 242 and the inner bottom wall of the box body 1. At the same time, through the floating of the floating block 241 in the upper clear liquid in the box body 1, it drives the whole floating block 241 and the filter block 242 to move up with the liquid level of the mixed liquid, thereby dynamically adjusting the sedimentation interval 25, so that the floating block 241 and the filter block 242 preferentially guide the light calcium carbonate particles in the upper layer of the mixed liquid to settle into the sedimentation interval 25 in the mixed liquid.

[0052] Further, referring to Figure 4 and Figure 6 as shown, the guiding pipe 260 is arranged in a telescopic pipe structure, and its telescopic section is connected to the floating block 241. At the same time, the filter block 242 itself has a certain weight to overcome the upward buoyancy of the mixed liquid on it in the early stage when the mixed liquid is injected into the box body 1, so as to achieve the effect of delaying the overall upward movement of the floating block 241, the filter block 242 and the telescopic section of the guiding pipe 260, and effectively guide the light calcium carbonate particles suspended in the mixed liquid to settle to the sedimentation interval 25 at the bottom of the box body 1.

[0053] At the same time, through the floating adjustment of the telescopic section of the guiding pipe 260 with the liquid level of the mixed liquid, the bent section of the guiding pipe 260 can always be kept in the clear liquid layer of the upper layer of the mixed liquid to ensure that the guiding pipe 260 always guides out the upper clear liquid. Further, through the floating adjustment of the telescopic section of the guiding pipe 260, it also effectively avoids guiding and discharging the mixed liquid in advance, achieving the effect of increasing the sedimentation effect of the light calcium carbonate particles.

[0054] Referring to Figure 4 and Figure 5 as shown, the diameter of the floating block 241 is larger than that of the filter block 242 and abuts against the inner wall of the box body 1. The limiting ring plate 243 is attached to the lower end of the floating block 241, and there is a gap between the outer edge of the filter block 242 and the inner wall of the box body 1.

[0055] Referring to Figure 4 and Figure 6 as shown, a filter sheet 261 is connected to the end of the guiding pipe 260 far from the connecting pipe 26 to filter the mixed liquid introduced into the guiding pipe 260 and the connecting pipe 26 to avoid sucking in the light calcium carbonate particles in the mixed liquid significantly.

[0056] Embodiment 2: Referring to Figure 7 and Figure 8As shown, based on the first embodiment, since the guiding arc plate 22 blocks the water flow input into the box body 1 through the water delivery pipe 23, the water flow will fall onto the overflow tray 21 and then overflow and fall into the bottom of the box body 1. During its use, there will always be some mixed liquid remaining on the overflow tray 21, and some light calcium carbonate particles in the mixed liquid may settle on the overflow tray 21. Therefore, in order to avoid the problem that the particles in the mixed liquid settle and accumulate on the overflow tray 21 and then need to be cleaned by the staff separately, at this time, the guiding arc plate 22 is rotatably connected to the connecting guide rod 220. A connecting rotating rod 27 corresponding to the water delivery pipe 23 is connected to the side of the guiding arc plate 22 close to the overflow tray 21. The end of the connecting rotating rod 27 close to the overflow tray 21 is arc-shaped. A number of guiding blades 270 are circumferentially connected to the connecting rotating rod 27. The guiding blades 270 are arranged in a curved shape. The guiding arc plate 22 is also circumferentially connected with a number of connecting arc plates 271 that are in contact and abutted against the arc surface of the overflow tray 21.

[0057] During use, after the water flow in the water delivery pipe 23 impacts the arc end of the connecting rotating rod 27, it will be guided and separated by the arc end so that the water flow is offset and guided to a number of guiding blades 270 on the connecting rotating rod 27. After the water flow is guided and impacts the guiding blades 270, different pressure distributions are generated on the surface of the guiding blades 270. Due to the curved shape of the guiding blades 270, a pressure difference is generated on the surface of the guiding blades 270, resulting in the generation of a tangential force. The tangential force generates a torque, causing a number of guiding blades 270 to drive the connecting rotating rod 27 and rotate around the connecting rotating rod 27 as the axis. The rotation of the connecting rotating rod 27 drives the guiding arc plate 22 and a number of connecting arc plates 271 to rotate. By the rotation of a number of guiding blades 270 and connecting arc plates 271, the mixed liquid injected into the box body 1 is rotated and displaced, so that there is a certain centrifugal force on the mixed liquid between the overflow tray 21 and the guiding arc plate 22, achieving the effect of pre-separating the mixed liquid and effectively increasing the subsequent sedimentation and separation efficiency of the light calcium carbonate in the mixed liquid.

[0058] At the same time, through the rotation of a number of connecting arc plates 271 on the overflow tray 21, the sediment particles deposited on the overflow tray 21 are scraped off and centrifugal force is applied, so that the mixed liquid accumulated on the overflow tray 21 is spun out of the overflow tray 21 and falls to the bottom of the box body 1. Through the rotational movement of the connecting rotating rod 27 and the guiding blades 270, the mixed liquid is pre-separated, and the sediment particles deposited on the overflow tray 21 are scraped off and thrown out from the overflow tray 21 by using centrifugal force. This not only reduces the sediment on the overflow tray 21, but also effectively improves the separation efficiency. The overall process is automatic and does not require the interference and assistance of the staff.

[0059] During operation: In the first step, the mixed liquid is introduced into the box body 1 from bottom to top through the water delivery pipe 23, impacts on the guiding arc plate 22, and the mixed liquid falls into the overflow tray 21 along the guiding arc plate 22.

[0060] In the second step: After being guided and limited by the guiding arc plate 22 and the overflow tray 21, the mixed liquid falls to the separation partition 24 and passes through the inclined guiding channel 240 on the separation partition 24, and then falls to the bottom of the box body 1. Since the density of light calcium carbonate is greater than that of the aqueous solution, under the action of gravity, the light calcium carbonate particles are continuously deposited in the sedimentation area 25 at the bottom of the box body 1.

[0061] In the third step: As the mixed liquid is continuously input, the overall liquid level in the box body 1 continuously rises. As the light calcium carbonate particles in the mixed liquid precipitate, the supernatant liquid above it is automatically discharged from the box body 1 through the guiding pipe 260 and the connecting pipe 26.

[0062] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

[0063] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
