Technical Field
[0001] This invention relates to the field of heavy calcium carbonate processing technology, and specifically to a heavy calcium carbonate homogenization tank. Background Technology
[0002] Heavy calcium carbonate is a commonly used powdered inorganic filler, usually made by grinding natural carbonate minerals such as calcite, marble, and limestone.
[0003] Currently, existing heavy calcium carbonate production systems typically include homogenization tanks to homogenize the heavy calcium carbonate and ensure uniform color. However, existing homogenization tanks only have discharge ports at the bottom of the tank. Therefore, when classifying heavy calcium carbonate later, material can only be taken from the discharge port at the bottom of the homogenization tank, which undoubtedly limits the material handling efficiency during the classification process. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art. This invention provides a heavy calcium carbonate homogenizing tank, which can effectively improve the material handling efficiency during heavy calcium carbonate classification by setting a material inlet for connecting an air classifier in an area outside the bottom of the tank.
[0005] This invention provides a heavy calcium carbonate homogenizing tank, comprising a base with a tank discharge port, a tank body disposed on the base, and a cover with a tank inlet disposed on the tank body. An air inflation device is provided in the base for agitating the powder in the tank body. A pulse bag filter is provided on the cover for separating the gas and powder.
[0006] The tank is divided into a top material area, a middle material area and a bottom material area from top to bottom. The top material area is provided with a first material inlet, which is used to connect to the inlet of the first air classifier; and / or the middle material area is provided with a second material inlet, which is used to connect to the inlet of the second air classifier.
[0007] Specifically, the volume ratio of the top material area, the middle material area, and the bottom material area is 3-4:1-2:1-2.
[0008] Specifically, the inflation device includes an inflation box disposed on the upper side of the base and an inflation pipeline disposed on the lower side of the base. The inflation box is composed of multiple inflation modules arranged in a circumferential array around the discharge port of the tank. Each inflation module is connected to the inflation pipeline through an inflation branch pipe. Each inflation branch pipe is equipped with a solenoid valve, which is used to control the gas flow rate of the inflation branch pipe.
[0009] Specifically, the air outlet surfaces of all the inflation modules connect to form the circumference of an inverted conical structure.
[0010] Specifically, any of the inflatable modules includes a module body with a cavity, a perforated plate embedded in the module body, and a filter cloth attached to the surface of the perforated plate, wherein the cavity of the module body is connected to the inflatable branch pipe.
[0011] Specifically, a positioning part is provided on the bottom surface of the end of any of the inflation modules away from the unloading port of the tank, and an annular positioning groove is provided on the upper side of the base, with the positioning parts of all inflation modules embedded in the annular positioning groove.
[0012] Specifically, the cover is also equipped with a one-way check valve for the air duct. The air inlet of the one-way check valve is connected to an air filter, and the air outlet of the one-way check valve is connected to the tank body.
[0013] Specifically, a conical powder disperser is suspended on the inner side of the cover, with the tip of the conical powder disperser facing the feed inlet of the tank.
[0014] Specifically, the first and second feeding ports are distributed on opposite sides of the tank.
[0015] Specifically, the first material inlet includes two first material inlets, which are arranged vertically.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] In the heavy calcium carbonate homogenization tank of the present invention, the tank body is divided into a top material zone, a middle material zone, and a bottom material zone from top to bottom. In addition to taking material from the bottom material zone through the tank discharge port, a first material outlet can be set separately in the top material zone to facilitate the first air classifier taking material from the top material zone; a second material outlet can also be set separately in the middle material zone to facilitate the second air classifier taking material from the middle material zone; or a first material outlet can be set in the top material zone and a second material outlet can be set in the middle material zone at the same time to facilitate the first air classifier and the second air classifier taking material simultaneously. In this way, by setting a material outlet for connecting the air classifier in an area other than the bottom of the tank body, the material taking efficiency during heavy calcium carbonate classification can be effectively improved.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] This invention provides a homogenization tank for heavy calcium carbonate. Figure 1 This diagram shows the overall structure of the heavy calcium carbonate homogenization tank in an embodiment of the present invention. Figure 2 An exploded structural diagram of a heavy calcium carbonate homogenizing tank according to an embodiment of the present invention is shown. The heavy calcium carbonate homogenizing tank includes a base 100 with a tank body discharge port 110, a tank body 200 disposed on the base 100, and a cover 300 with a tank body inlet 310 disposed on the tank body 200; please refer to [link to relevant documentation]. Figure 2 An inflation device 400 is provided in the base 100, and the inflation device 400 is used to inflate and agitate the powder in the tank 200; please refer to Figure 1 or Figure 2 The cover 300 is equipped with a pulse bag dust collector 500, which is used to separate gas and powder. The tank 200 is divided into a top material area 210, a middle material area 220 and a bottom material area 230 from top to bottom. The top material area 210 is provided with a first material inlet 211, which is used to connect to the inlet of the first air classifier. And / or the middle material area 220 is provided with a second material inlet 221, which is used to connect to the inlet of the second air classifier.
[0032] In the heavy calcium carbonate homogenizing tank of the present invention, the tank body 200 is divided into a top material area 210, a middle material area 220 and a bottom material area 230 from top to bottom. In addition to taking material from the bottom material area 230 through the tank discharge port 110, a first material outlet 211 can be set separately in the top material area 210 to facilitate the first air classifier to take material from the top material area 210; a second material outlet 221 can also be set separately in the middle material area 220 to facilitate the second air classifier to take material from the middle material area 220; or the first material outlet 211 can be set in the top material area 210 and the second material outlet 221 can be set in the middle material area 220 at the same time to facilitate the first air classifier and the second air classifier to take material at the same time. In this way, by setting a material outlet for connecting the air classifier in an area other than the bottom of the tank body 200, the material taking efficiency during heavy calcium carbonate classification can be effectively improved.
[0033] Furthermore, when the aeration device 400 agitates and stirs the heavy calcium carbonate in the tank 200, it can achieve homogenization or suspension stratification of the heavy calcium carbonate in the tank 200 by adjusting the aeration mode. When the aeration device 400 performs zoned cyclic aeration or grouped alternating aeration, it can make the heavy calcium carbonate in the tank 200 circulate and mix thoroughly, thereby achieving homogenization of the heavy calcium carbonate in the tank 200. When the aeration device 400 performs continuous overall aeration, it can make the heavy calcium carbonate in the tank 200 fluidized and suspended. Under the action of gravity, the heavy calcium carbonate will form different regional distributions according to the size of the powder particles, thereby achieving suspension stratification of the heavy calcium carbonate in the tank 200.
[0034] When the heavy calcium carbonate in tank 200 is suspended and stratified, the first feed port 211 in the top material zone 210 is connected to the feed port of the first air classifier, which can extract finer heavy calcium carbonate as needed; the second feed port 221 in the middle material zone 220 is connected to the feed port of the second air classifier, which facilitates the acquisition of medium-sized heavy calcium carbonate; and the tank discharge port 110 is connected to the feed port of the third air classifier to process the larger particles of heavy calcium carbonate at the bottom. This not only improves the efficiency of subsequent classification but also reduces the energy consumption of subsequent classification.
[0035] When the heavy calcium carbonate in the tank 200 is in a homogenized state, the powder output from the first feed port 211, the second feed port 221 and the tank discharge port 110 is basically the same and has a uniform color.
[0036] In some specific embodiments, the volume ratio of the top material zone 210, the middle material zone 220, and the bottom material zone 230 ranges from 3 to 4:1 to 2:1 to 2. This ratio design can better achieve the suspension stratification and classification of heavy calcium carbonate. Preferably, the volume ratio of the top material zone 210, the middle material zone 220, and the bottom material zone 230 is 4:2:1, which is beneficial for better separation of heavy calcium carbonate with smaller particle size.
[0037] Specifically, the amount of heavy calcium carbonate loaded in the tank 200 shall not exceed one-half of the volume of the tank 200, so as to ensure that the tank 200 has sufficient space for aeration and stirring, which is conducive to the aeration device 400 fully exerting its aeration and stirring capabilities.
[0038] Figure 3 A cross-sectional view of the bottom of the heavy calcium carbonate homogenization tank in an embodiment of the present invention is shown. The air filling device 400 includes an air filling box 410 disposed on the upper side of the base 100 and an air filling pipeline 420 disposed on the lower side of the base 100. Figure 4A schematic diagram of the structure of the air-filled box in an embodiment of the present invention is shown. The air-filled box 410 is composed of multiple air-filled modules 411 arranged in a circular array around the unloading port 110 of the tank body. Figure 5 A schematic diagram of the inflation pipeline in an embodiment of the present invention is shown. Any one of the inflation modules 411 is connected to the inflation pipeline 420 through an inflation branch pipe 421. Each inflation branch pipe 421 is provided with a solenoid valve 422, which is used to control the gas flow rate of the inflation branch pipe 421.
[0039] Please see Figure 3 , Figure 4 and Figure 5 In the inflation device 400, high-pressure gas enters the inflation branch pipe 421 through the inflation pipeline 420, then enters the inflation module 411 through the solenoid valve 422, and finally enters the tank 200 to agitate the heavy calcium carbonate. Multiple inflation modules 411 arranged in a circumferential array around the tank discharge port 110 can achieve various inflation modes with the cooperation of the solenoid valve 422, such as zoned cyclic inflation, grouped alternating inflation, and overall continuous inflation.
[0040] Specifically, there are at least 6 aeration modules 411, which provides a good aeration and stirring effect for the heavy calcium carbonate in the tank 200. Optionally, there may be 6, 8, 10, 12, 14, 16, 18, or 20 aeration modules 411, etc.
[0041] For example, the inflation box 410 is composed of six inflation modules 411 arranged in a circular array around the discharge port 110 of the tank body. The six inflation modules 411 are numbered A, B, C, D, E, and F in sequence. In the zoned circulation inflation mode, A, B, C, D, E, and F sequentially inflate the tank 200 and continuously circulate, allowing the heavy calcium carbonate in the tank 200 to circulate and mix thoroughly, thereby achieving homogenization of the heavy calcium carbonate in the tank 200. In the grouped alternating inflation mode, A, B, and C form one group, and D, E, and F form another group; or A, C, and E form one group, and B, D, and F form another group; or A and D form one group, B and E form another group, and C and F form another group; each group of inflation modules 411 alternately inflates the tank 200 and continuously circulates, allowing the heavy calcium carbonate in the tank 200 to mix thoroughly, thereby achieving homogenization of the heavy calcium carbonate in the tank 200. In the overall continuous inflation mode, A, B, C, D, E and F simultaneously and continuously inflate the tank 200, which can fluidize and suspend the heavy calcium carbonate in the tank 200. Under the action of gravity, the heavy calcium carbonate will form different regional distributions according to the size of the powder particles, thereby realizing the suspension and stratification of the heavy calcium carbonate in the tank 200.
[0042] For further details, please refer to Figure 5The inflation pipeline 420 has several air inlet branches 423 on the side away from the tank 200. All air inlet branches 423 are connected to a compressed air storage tank, which provides high-pressure gas to the inflation pipeline 420. The high-pressure gas in the compressed air storage tank has undergone oil removal, water removal, and dust removal treatment, making it dry and clean, thus preventing contamination of the heavy calcium carbonate in the tank 200. Moreover, the compressed air storage tank can provide high-pressure gas of 60-90 kPa, which is sufficient to fully agitate the heavy calcium carbonate in the tank 200.
[0043] In some specific embodiments, please refer to Figure 3 The air outlet surfaces of all the air-filling modules 411 are connected to form the circumference of the inverted cone structure, which not only enhances the air-filling and agitation effect of the air-filling modules 411, but also facilitates the accumulation of heavy calcium carbonate at the discharge port 110 of the tank for discharge.
[0044] Specifically, the angle between the outlet surface of any of the aeration modules 411 and the horizontal plane ranges from 8° to 18°. A suitable angle can guide high-pressure gas into the tank 200 at a certain angle, which can not only more effectively agitate the heavy calcium carbonate in the tank 200, but also reduce the accumulation of high-pressure gas at the top of the tank 200 and avoid the formation of local high-pressure areas. If the angle between the outlet surface of the aeration module 411 and the horizontal plane is greater than 18°, it will affect the agitation effect of the high-pressure gas in the vertical direction and will also increase the interference between the relatively distributed aeration modules 411. If the angle between the outlet surface of the aeration module 411 and the horizontal plane is less than 8°, it will be difficult to push the heavy calcium carbonate from the bottom of the tank to the center of the tank 200, which will not only affect the homogenization efficiency of the heavy calcium carbonate, but also affect the discharge efficiency of the heavy calcium carbonate from the tank discharge port 110.
[0045] Figure 6 A schematic diagram of the top structure of the inflation module in an embodiment of the present invention is shown. Each inflation module 411 includes a module body 4111 with a cavity, a perforated plate 4112 embedded in the module body 4111, and a filter cloth (not shown in the figure) attached to the surface of the perforated plate 4112. The cavity of the module body 4111 is connected to the inflation branch pipe 421. The filter cloth can prevent heavy calcium carbonate from entering the cavity of the module body 4111, avoiding pipe blockage; the perforated plate 4112 can provide good support for the filter cloth without affecting inflation, preventing the filter cloth from being crushed by heavy calcium carbonate.
[0046] Specifically, the thickness of the perforated plate 4112 ranges from 2 to 5 cm, the mesh diameter ranges from 0.5 to 1.0 cm, and the mesh density ranges from 10 to 15 meshes per square decimeter. Such a perforated plate 4112 allows a large amount of high-pressure gas to pass through, and it also has good strength, high load-bearing capacity, and a long service life. Preferably, the thickness of the perforated plate 4112 is 5 cm, the mesh diameter is 1.0 cm, and the mesh density is 12 meshes per square decimeter, which allows it to withstand enormous pressure during long-term use and is not easily damaged.
[0047] Figure 7 A schematic diagram of the bottom structure of the inflation module in an embodiment of the present invention is shown. A positioning part 430 is provided on the bottom surface of any inflation module 411 at the end away from the tank discharge port 110. Figure 8 A schematic diagram of the base structure in an embodiment of the present invention is shown. The base 100 has an annular positioning groove 120 on its upper side; please refer to... Figure 3 The positioning part 430 of all inflation modules 411 is embedded in the annular positioning groove 120; through the cooperation of the positioning part 430 and the annular positioning groove 120, the complicated positioning operation is eliminated, which helps to reduce the installation difficulty of the inflation module 411 and improve the installation efficiency of the inflation module 411.
[0048] For details, please refer to Figure 7 Each of the positioning portions 430 includes an arc-shaped protrusion 431 and a square protrusion 432 connected as one piece; see also Figure 8 The annular positioning groove 120 includes an annular main groove 121 and a plurality of square grooves 122 evenly distributed along the annular main groove 121. The arc-shaped protrusion 431 is embedded in the annular main groove 121, and the square protrusion 432 is embedded in the corresponding square groove 122, which can effectively improve the installation stability of the inflation module 411 and prevent the inflation module 411 from rotating.
[0049] For further details, please refer to Figure 3 The bottom of the tank 200 presses the positioning parts 430 of all the inflation modules 411 into the annular positioning groove 120; moreover, a connecting ring 240 is provided around the bottom of the tank 200, and the connecting ring 240 is fixedly connected to the base 100, so that all the inflation modules 411 (i.e. inflation boxes 410) are wrapped inside the tank 200, which not only ensures the installation stability of the inflation boxes 410, but also prevents the leakage of heavy calcium carbonate.
[0050] Figure 9A schematic diagram of the top surface structure of the cover body in an embodiment of the present invention is shown. Since the cover body 300 is equipped with a pulse bag dust collector 500, which can separate heavy calcium carbonate and gas, the feed port 310 of the tank body can be directly connected to the discharge port of the grinding mill to directly receive the heavy calcium carbonate output by the grinding mill, which is beneficial to simplifying the structure of the heavy calcium carbonate production system.
[0051] Optionally, the tank inlet 310 can also be connected to the outlet of the grinding mill via a dust collector. The dust collector separates the heavy calcium carbonate output from the grinding mill and then transports it to the heavy calcium carbonate homogenization tank, which helps to improve the working stability of the heavy calcium carbonate production system.
[0052] Furthermore, the powder particles that do not meet the requirements separated by the first and second air classifiers will be reintroduced into the tank 200 from the tank inlet 310 and finally discharged from the tank outlet 110.
[0053] In some specific embodiments, please refer to Figure 9 The cover 300 is also equipped with a one-way check valve 320 for the air duct. The air inlet of the one-way check valve 320 is connected to an air filter 330, and the air outlet of the one-way check valve 320 is connected to the tank 200. Through the cooperation of the one-way check valve 320 and the air filter 330, clean air can be supplied to the tank 200 in one direction without preventing the leakage of heavy calcium carbonate. This is used to balance the negative pressure when the air classifier extracts heavy calcium carbonate from the tank 200.
[0054] Figure 10 A schematic diagram of the bottom structure of the cover body in an embodiment of the present invention is shown. A conical powder disperser 340 is suspended on the inner side of the cover body 300, and the tip of the conical powder disperser 340 is directly opposite the feed inlet 310 of the tank. When heavy calcium carbonate is input from the feed inlet 310 of the tank, it can be dispersed by the conical powder disperser 340, which helps to improve the uniformity of heavy calcium carbonate in the tank 200 and can reduce the difficulty of subsequent homogenization.
[0055] In some specific embodiments, please refer to Figure 1 The first feeding port 211 and the second feeding port 221 are distributed on opposite sides of the tank body 200, which helps to avoid interference between the first air classifier and the second air classifier when feeding materials at the same time.
[0056] In some specific embodiments, please refer to Figure 1The first feed port 211 includes two first feed sub-ports, which are arranged vertically, which helps to increase the unit feed volume of the first air classifier. Especially when heavy calcium carbonate is suspended and stratified in the tank 200, the two vertically arranged first feed sub-ports can enable the first air classifier to quickly and extensively extract fine heavy calcium carbonate.
[0057] In some specific embodiments, please refer to Figure 8 The base 100 is surrounded by at least three base plates 130. The heavy calcium carbonate homogenizing tank stands on the ground through the base plates 130. The at least three base plates 130 ensure that the heavy calcium carbonate homogenizing tank can stand stably on the ground.
[0058] Specifically, a protective plate 140 extends between the upper ends of adjacent base plates 130; please refer to Figure 3 The protective plate 140 surrounds the inflation tube 420, which can protect the inflation tube 420 on the one hand and prevent the inflation tube 420 from being ejected randomly in case of an accident on the other hand.
[0059] For further details, please refer to Figure 3 and Figure 8 The base 100 is provided with a tank unloading pipe 150 at its bottom. The upper end of the tank unloading pipe 150 is connected to the tank unloading port 110. The lower end of the tank unloading pipe 150 extends out from the gap between the base plates 130 to facilitate the discharge of heavy calcium carbonate.
[0060] The heavy calcium carbonate homogenizing tank of the present invention can effectively improve the material handling efficiency during heavy calcium carbonate classification by setting a first feed port 211 and / or a second feed port 221 for connecting an air classifier in a region outside the bottom of the tank body 200; moreover, by adjusting the aeration mode of the aeration device 400, the homogenization or suspension stratification of heavy calcium carbonate in the tank body 200 can be achieved, which can be selected according to specific needs.
[0061] When the heavy calcium carbonate in the tank 200 is suspended and stratified, finer heavy calcium carbonate can be extracted from the first feed port 211 of the top feed area 210, medium-sized heavy calcium carbonate can be obtained from the second feed port 221 of the middle feed area 220, and larger particles of heavy calcium carbonate can be processed from the tank discharge port 110 of the bottom feed area 230. This is beneficial to improving the efficiency of subsequent classification and reducing the energy consumption of subsequent classification. When the heavy calcium carbonate in the tank 200 is in a homogenized state, the powder output from the first feed port 211, the second feed port 221 and the tank discharge port 110 is basically the same, which can ensure that the heavy calcium carbonate has a uniform color.
[0062] The above provides a detailed description of a heavy calcium carbonate homogenizing tank provided by the embodiments of the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
