Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material batching, in particular to a valve array system. BACKGROUND

[0002] The valve array system with multiple flow channels and valves is widely used in the material batching process in the fields of chemical industry, food, pharmaceuticals, etc. because it can simultaneously transport multiple materials. In the prior art, in order to complete online mixing of multiple materials during the transportation process, an online mixer is additionally arranged on the feed pipe of some valve array systems.

[0003] However, the current valve array system can only realize the basic mixing function, and cannot meet the application scenarios that require high-strength shear homogenization, nor can it flexibly switch between independent transportation and mixing modes according to process requirements. Moreover, the implementation of the mixing function in the valve array system usually requires a mixer to be independently configured for each material pipe, resulting in a redundant and complex structure of the valve array system and a significant increase in equipment cost. In addition, the existing valve array system needs to be shut down for manual emptying and cleaning when switching materials or production batches, which not only leads to low efficiency of the emptying and cleaning process, but also cannot guarantee coverage of all pipelines. SUMMARY

DETAILED DESCRIPTION

[0021] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0022] <First embodiment>

[0023] Figure 1 is a structural schematic diagram of a valve array system 100 provided by the present embodiment, referring to Figure 1 The valve array system 100 provided by the present embodiment includes a first feed pipe 1, a second feed pipe 2, a feed pipeline 4, and a valve array group 3. The feed pipeline 4 is connected with the first feed pipe 1 and the second feed pipe 2; a homogenizing module 6 is connected with the feed pipeline 4; the valve array group 3 is configured to selectively connect the following flow paths: a first flow path connecting the first feed pipe 1 with the homogenizing module 6 and disconnecting the second feed pipe 2 from the homogenizing module 6; a second flow path connecting the second feed pipe 2 with the homogenizing module 6 and disconnecting the first feed pipe 1 from the homogenizing module 6; and a third flow path connecting the first feed pipe 1 and the second feed pipe 2 with the homogenizing module 6.

[0024] In the present embodiment, the first feed pipe 1 and the second feed pipe 2 are respectively used to transport material A and material B. Referring to Figure 1 , the first feed pipe 1 has a first feed port 11 and a first discharge port 12 at two ends respectively, and the second feed pipe 2 has a second feed port 21 and a second discharge port 22 at two ends respectively. The material A and the material B enter the valve array system 100 through the first feed port 11 and the second feed port 21 respectively. The valve array group 3 includes a plurality of valves arranged in the respective pipelines of the valve array system 100. By controlling the opening and closing of the valves at the specified pipeline positions, the material A and the material B can be circulated in the valve array system 100 along the set route. In other embodiments, the materials entering the first feed pipe 1 and the second feed pipe 2 can also be the same kind of material, and the same material is transported to different equipment through the first feed pipe 1 and the second feed pipe 2 respectively; or, part of the same material is directly transported by the pipelines of the valve array system 100, and another part of the material is homogenized in the valve array system 100 and then transported outwards. The kind of material entering the valve array system 100 is not specifically limited here.

[0025] Referring to Figure 1, the first valve 301 and the second valve 302 are arranged in the first feeding pipe 1 in sequence along the material flow direction, and the third valve 303 and the fourth valve 304 are arranged in the second feeding pipe 2 in sequence along the material flow direction. When the materials A and B used in production do not need to be mixed or processed, and only the pipeline of the valve array system 100 is used to directly transport the materials to the next production process, the first valve 301 and the second valve 302 in the first feeding pipe 1 and the third valve 303 and the fourth valve 304 in the second feeding pipe 2 can be directly opened, so that the materials A and B flow along the pipelines of the first feeding pipe 1 and the second feeding pipe 2 respectively, and are discharged from the first discharge port 12 and the second discharge port 22 respectively.

[0026] Because there are many types of materials used in actual production, if the types of materials entering the pipelines of the valve array system 100 twice in succession are different, the materials remaining in the pipelines last time may mix into the currently flowing materials, resulting in cross contamination between different types of materials, and further affecting the quality of the subsequently produced products. In addition, because the materials may carry a certain amount of moisture, part of the residual water may be left in the pipelines of the valve array system 100 during the conveying process. If this part of residual water is not removed from the pipelines in time, it may cause pipeline corrosion, microbial growth, and mixing into new materials when switching materials to affect their purity. Therefore, after each material passes through the valve array system 100 and completes the conveying, the residual materials and residual water in the pipelines need to be emptied. Considering that part of the pipelines may not convey materials each time the valve array system 100 is used, if all the pipelines in the valve array system 100 are directly emptied, on the one hand, the efficiency of emptying is low; on the other hand, it may also cause mixing of residual materials in different pipeline sections, increasing the risk of cross infection of materials in the valve array system 100.

[0027] Therefore, in the present embodiment, the valve array system 100 further comprises a plurality of bypass pipelines 5 for discharging the residual materials and residual water in the pipelines to the outside. Referring to Figure 1 , the plurality of bypass pipelines 5 are connected with the first feeding pipe 1, the second feeding pipe 2 and the material conveying pipeline 4 at a plurality of positions respectively, and one end of the bypass pipeline 5 is connected with the outside. Specifically, referring to Figure 1The pipeline between the first valve 301 and the second valve 302 is provided with a first bypass pipeline 51, and the pipeline between the third valve 303 and the fourth valve 304 is provided with a second bypass pipeline 52; the pipeline between the second valve 302 and the first discharge port 12 is provided with a third bypass pipeline 53, and the pipeline between the fourth valve 304 and the second discharge port 22 is provided with a fourth bypass pipeline 54. In order to make the residual material discharge process controllable, the fifth valve 305, the sixth valve 306, the seventh valve 307 and the eighth valve 308 are respectively arranged on the first bypass pipeline 51, the second bypass pipeline 52, the third bypass pipeline 53 and the fourth bypass pipeline 54.

[0028] The residual material discharge process in the first feeding pipe 1 is as follows: first, the first valve 301 and the second valve 302 are closed, then the fifth valve 305 is opened, so that the residual material and residual water in the pipe section between the first valve 301 and the second valve 302 of the first feeding pipe 1 are discharged through the first bypass pipeline 51. After the above discharge process is completed, the seventh valve 307 is opened, so that the residual material and residual water in the pipe section between the second valve 302 and the first discharge port 12 of the first feeding pipe 1 are discharged through the third bypass pipeline 53.

[0029] The residual material discharge process in the second feeding pipe 2 is as follows: first, the third valve 303 and the fourth valve 304 are closed, then the sixth valve 306 is opened, so that the residual material and residual water in the pipe section between the third valve 303 and the fourth valve 304 of the second feeding pipe 2 are discharged through the second bypass pipeline 52. After the above discharge process is completed, the eighth valve 308 is opened, so that the residual material and residual water in the pipe section between the fourth valve 304 and the second discharge port 22 of the second feeding pipe 2 are discharged through the fourth bypass pipeline 54.

[0030] <Second embodiment>

[0031] When multiple materials are used in production, there may be different use requirements for the physical states such as particle size and viscosity of different materials. In order to enable the valve array system 100 to simultaneously meet the independent conveying and homogenization processing requirements of single or multiple materials, in this embodiment, the opening and closing of the valve at a specific position in the valve array group 3 is adjusted to connect the second flow path. When the second flow path is connected, the material A can be directly conveyed to other production processes by the first feeding pipe 1, and at the same time, the material B entering the second feeding pipe 2 from the second feeding port 21 is homogenized in the homogenization module 6 and then flows back to the second feeding pipe 2 and is conveyed to the outside through the second discharge port 22.

[0032] Reference Figure 1 The specific operation of connecting the second flow path is as follows:

[0033] For material A, open the first valve 301 and the second valve 302, and the material A in the first inlet port 11 enters the valve array system 100, directly flows along the inside of the first feeding pipe 1 to the first outlet port 12, and is transported to the subsequent production equipment. After the material A is transported, the residual material A and residual water in the first feeding pipe 1 are emptied, the first valve 301 and the second valve 302 are closed, then the fifth valve 305 is opened, and the residual material and residual water in the pipe section between the first valve 301 and the second valve 302 of the first feeding pipe 1 are emptied through the first bypass pipe 51. Finally, the seventh valve 307 is opened, and the residual material and residual water in the pipe section between the second valve 302 and the first outlet port 12 of the first feeding pipe 1 are emptied through the third bypass pipe 53.

[0034] For material B, in the present embodiment, the connection position of the material flow pipe 4 and the second feeding pipe 2 is sequentially provided with the thirteenth valve 313, the fourteenth valve 314, the fifteenth valve 315, and the sixteenth valve 316 in the material flow direction. The part of the material flow pipe 4 between the fourteenth valve 314 and the fifteenth valve 315 is located in the homogenizing module 6, and the material flow pipe 4 in the homogenizing module 6 is further provided with the twenty-first valve 321. The material flow pipe 4 before and after the twenty-first valve 321 is connected with the homogenizing inlet 613 and the homogenizing outlet 614 of the homogenizing machine 61 in the homogenizing module 6. The second twenty-second valve 322 is arranged on the pipe between the material flow pipe 4 and the homogenizing inlet 613, and the second twenty-third valve 323 is arranged on the pipe between the material flow pipe 4 and the homogenizing outlet 614. First, the material B is input into the valve array system 100 through the second inlet port 21, and then the thirteenth valve 313 and the fourteenth valve 314 are opened, so that the material B in the second feeding pipe 2 enters the material flow pipe 4 in sequence through the thirteenth valve 313 and the fourteenth valve 314. Then the twenty-second valve 322 is opened and the twenty-first valve 321 is kept closed, so that the material B in the material flow pipe 4 enters the homogenizing machine 61 in sequence through the twenty-second valve 322 and the homogenizing inlet 613, and is uniformly dispersed to the required physical state by the homogenizing machine 61. In order to make the homogenizing effect better, in the present embodiment, the homogenizing machine 61 in the homogenizing module 6 is selected as a high-pressure shearing homogenizing machine, so as to uniformly disperse the material particles to the micron level as much as possible. After the material B is homogenized in the homogenizing machine 61, the twenty-third valve 323 is opened, so that the material B in the homogenizing machine 61 reflows into the material flow pipe 4 in sequence through the homogenizing outlet 614 and the twenty-third valve 323. Then the fifteenth valve 315 and the sixteenth valve 316 are opened, so that the material B in the material flow pipe 4 enters the second feeding pipe 2 in sequence through the fifteenth valve 315 and the sixteenth valve 316, and is finally discharged from the second outlet port 22 to the outside of the valve array system 100 for subsequent production use.

[0035] After the material B which has been homogenized is discharged from the second discharge port 22, the residual material and residual water in the pipeline need to be emptied. Referring to Figure 1 The pipeline between the thirteenth valve 313 and the fourteenth valve 314 is provided with a seventh bypass pipeline 57, and the pipeline between the fifteenth valve 315 and the sixteenth valve 316 is provided with an eighth bypass pipeline 58. The seventh bypass pipeline 57 and the eighth bypass pipeline 58 are respectively provided with a nineteenth valve 319 and a twentieth valve 320. In the flow direction of the material in the material passing pipeline 4, the two ends of the material passing pipeline 4 are sequentially provided with a twenty-fourth valve 324 and a twenty-fifth valve 325, and the two ends are connected to the outside.

[0036] The specific emptying operation of the residual material B and the residual water is as follows: first, the thirteenth valve 313, the fourteenth valve 314, the fifteenth valve 315 and the sixteenth valve 316 are closed, and then the nineteenth valve 319 and the twentieth valve 320 are opened, so that the pipeline between the thirteenth valve 313 and the fourteenth valve 314 and the pipeline between the fifteenth valve 315 and the sixteenth valve 316 are respectively connected to the outside of the valve array system 100 through the seventh bypass pipeline 57 and the eighth bypass pipeline 58, so as to discharge the residual material B and the residual water in the above pipeline section to the outside of the valve array system 100. Then, the twenty-fourth valve 324 and the twenty-fifth valve 325 are opened, and the other remaining valves in the valve array group 3 are all in the closed state, and finally the residual material B in the material passing pipeline 4 is emptied.

[0037] In this embodiment, the material A only passes through the first feeding pipe 1, and the material B passes through the second material pipe, the material passing pipeline 4 and the homogenizing module 6, and the flow pipelines of the two materials in the valve array system 100 do not interfere with each other, which can effectively achieve the effect of preventing mixing of materials.

[0038] <Third embodiment>

[0039] In this embodiment, by adjusting the opening and closing of the valves at a specific position in the valve array group 3, the first flow path is connected. When the first flow path is connected, the material B is directly conveyed to other production processes from the second feeding pipe 2, and at the same time, the material A entering the first feeding pipe 1 from the first feeding port 11 is homogenized in the homogenizing module 6 and then flows back to the first feeding pipe 1 and is conveyed to the outside through the first discharge port 12.

[0040] Referring to Figure 1 The specific operation of connecting the first flow path is as follows:

[0041] For material B, open the third valve 303 and the fourth valve 304, and the material B entering the valve array system 100 from the second inlet 21 directly flows along the inside of the second feeding pipe 2 to the second outlet 22, and is transported to the subsequent production equipment. After the transportation of the material B is completed, the residual material B and residual water in the second feeding pipe 2 are emptied, the third valve 303 and the fourth valve 304 are closed, and then the sixth valve 306 is opened, so that the residual material and residual water in the pipe section between the third valve 303 and the fourth valve 304 of the second feeding pipe 2 are emptied through the second bypass pipe 52. After the above emptying process is completed, the eighth valve 308 is opened, so that the residual material and residual water in the pipe section between the fourth valve 304 and the second outlet 22 of the second feeding pipe 2 are emptied through the fourth bypass pipe 54.

[0042] For material A, in the present embodiment, the connection positions of the material flow passage 4 and the first feeding pipe 1 along the material flow direction are sequentially provided with the ninth valve 309, the tenth valve 310, the eleventh valve 311, and the twelfth valve 312. The material flow passage 4 connected with the first feeding pipe 1 and the second feeding pipe 2 is a common passage. First, the material A is input into the valve array system 100 through the first inlet 11, and then the ninth valve 309 and the tenth valve 310 are opened, so that the material A in the first feeding pipe 1 enters the material flow passage 4 in sequence through the ninth valve 309 and the tenth valve 310. Then the twenty-second valve 322 is opened and the twenty-first valve 321 is kept closed, so that the material A in the material flow passage 4 flows into the homogenizer 61 in sequence through the twenty-second valve 322 and the homogenizer inlet 613, and is uniformly dispersed to the required physical state by the homogenizer 61. After the homogenization of the material A in the homogenizer 61 is completed, the twenty-third valve 323 is opened, so that the material A in the homogenizer 61 reflows into the material flow passage 4 in sequence through the homogenizer outlet 614 and the twenty-third valve 323. Then the eleventh valve 311 and the twelfth valve 312 are opened, so that the material A in the material flow passage 4 enters the first feeding pipe 1 in sequence through the eleventh valve 311 and the twelfth valve 312, and is finally discharged from the first outlet 12 to the outside of the valve array system 100 for subsequent production.

[0043] After the above material A which has completed the homogenization is completely discharged from the second outlet 22, the residual material and residual water in the pipe through which the material A flows need to be emptied. Referring to Figure 1 , the fifth bypass pipe 55 is arranged in the pipe between the ninth valve 309 and the tenth valve 310, and the sixth bypass pipe 56 is arranged in the pipe between the eleventh valve 311 and the twelfth valve 312. The fifth bypass pipe 55 and the sixth bypass pipe 56 are respectively provided with the seventeenth valve 317 and the eighteenth valve 318.

[0044] The specific emptying operation of the residual material A is as follows: first, the ninth valve 309, the tenth valve 310, the eleventh valve 311 and the twelfth valve 312 are closed, then the seventeenth valve 317 and the eighteenth valve 318 are opened, so that the pipeline between the ninth valve 309 and the tenth valve 310 and the pipeline between the eleventh valve 311 and the twelfth valve 312 are respectively communicated with the outside of the valve array system 100 through the fifth bypass pipeline 55 and the sixth bypass pipeline 56, so as to discharge the residual material A and the residual water in the above-mentioned pipeline segments to the outside of the valve array system 100. Finally, the twenty-fourth valve 324 and the twenty-fifth valve 325 are opened, and the other remaining valves in the valve array group 3 are all in the closed state, so as to complete the emptying of the residual material A and the residual water in the over-material pipeline 4.

[0045] <Fourth embodiment>

[0046] For the working condition that the material A and the material B need to be mixed and homogenized in production, in the present embodiment, the third flow path is connected by adjusting the opening and closing of the valves at a specific position in the valve array group 3. After the third flow path is connected, the material A and the material B can be mixed with each other and subjected to homogenization treatment together through the valve array system 100.

[0047] Reference Figure 1 The specific operation of connecting the third flow path is as follows:

[0048] The material A and the material B are respectively input into the valve array system 100 through the first feed inlet 11 and the second feed inlet 21, and the ninth valve 309, the tenth valve 310 and the thirteenth valve 313, the fourteenth valve 314 are opened at the same time. The material A in the first feed pipe 1 enters the over-material pipeline 4 in sequence through the ninth valve 309 and the tenth valve 310, and the material B in the second feed pipe 2 enters the over-material pipeline 4 in sequence through the thirteenth valve 313 and the fourteenth valve 314. Then the twenty-second valve 322 is opened, so that the material A and the material B in the over-material pipeline 4 enter the homogenizer 61 in sequence through the twenty-second valve 322 and the homogenization inlet 613, and are subjected to uniform mixing and high-pressure shearing treatment at the same time. After the homogenization treatment is completed, the material C meeting the production requirements is formed. Then the twenty-third valve 323, the fifteenth valve 315 and the sixteenth valve 316 are opened, so that the material C in the homogenizer 61 enters the second feed pipe 2 in sequence through the homogenization outlet 614, the twenty-third valve 323, the fifteenth valve 315 and the sixteenth valve 316, and is finally discharged from the second discharge outlet 22 to the outside of the valve array system 100 for subsequent production use.

[0049] After the material C formed after the above homogenization treatment is completely discharged from the second discharge outlet 22, the residual material and the residual water flowing through the pipeline need to be emptied.

[0050] The specific emptying process is as follows:

[0051] First, the ninth valve 309, the tenth valve 310, the eleventh valve 311, the twelfth valve 312, the thirteenth valve 313, the fourteenth valve 314, the fifteenth valve 315 and the sixteenth valve 316 are closed, and then the seventeenth valve 317, the eighteenth valve 318, the nineteenth valve 319 and the twentieth valve 320 are opened, and the residual material and residual water in the pipe sections between the ninth valve 309 and the tenth valve 310, between the eleventh valve 311 and the twelfth valve 312, between the thirteenth valve 313 and the fourteenth valve 314, and between the fifteenth valve 315 and the sixteenth valve 316 are emptied to the outside by using the fifth bypass pipe 55, the sixth bypass pipe 56, the seventh bypass pipe 57 and the eighth bypass pipe 58. Finally, the twenty-fourth valve 324 and the twenty-fifth valve 325 are opened, and the other remaining valves in the valve array group 3 are in a closed state, thereby completing the emptying of the residual material A, the material B, the material C and the residual water in the material pipeline 4.

[0052] <5th Embodiment>

[0053] In this embodiment, when the valve array system 100 completes the delivery, homogenization and / or mixing homogenization task of the current batch of material, the valve array group 3 can be quickly cleaned by adjusting the valve opening and closing of the valve array group 3, so as to avoid the cross contamination between different materials when switching materials for the next batch of production. And improve the cleaning efficiency of the valve array system 100, shorten the downtime required by the cleaning process of the valve array system 100, thereby further improving the product quality and production efficiency.

[0054] The specific operation of the cleaning process of the valve array system 100 is as follows:

Referring to Figure 1 During the cleaning process, every ten seconds, the fifth valve 305, the seventh valve 307, the twelfth valve 312 and the eighteenth valve 318 are opened and maintained in an open state for two seconds, thereby cleaning the inside of the first bypass pipe 51, the third bypass pipe 53 and the sixth bypass pipe 56.

[0056] The pipeline between the second inlet port 21 and the second outlet port 22 is cleaned, the cleaning liquid is input from the second inlet port 21 to the valve array system 100, the third valve 303 and the fourth valve 304 are opened, and the pipeline between the second inlet port 21 and the second outlet port 22 in the second feed pipe 2 is cleaned. Referring to Figure 1 During the cleaning process, every ten seconds, the sixth valve 306, the eighth valve 308, the sixteenth valve 316 and the twentieth valve 320 are opened and maintained in the opened state for two seconds, so that the above-mentioned valves and the second bypass pipeline 52, the fourth bypass pipeline 54 and the eighth bypass pipeline 58 inside are cleaned.

Referring to Figure 1 During the cleaning process, every ten seconds, the seventeenth valve 317, the nineteenth valve 319 and the twenty-fourth valve 324 are opened and maintained in the opened state for two seconds, so that the above-mentioned valves and the fifth bypass pipeline 55, the seventh bypass pipeline 57 and the overfeed pipeline 4 inside are cleaned.

[0058] In the above embodiment, the homogenizer 61 of the homogenizing module 6 contains process water, which is used to assist the homogenizer 61 in homogenizing the material, so that the physical parameters such as particle size and viscosity of the material better meet the process needs. However, as the homogenizer 61 continues to operate, the process water in the homogenizer 61 may be lost together with the material, so it is necessary to supplement the process water in the homogenizer 61 periodically or according to the actual operation time, power and state of the homogenizer 61. Referring to Figure 1 The homogenizer 61 is provided with a process water inlet 611, and a twenty-sixth valve 612 is further arranged on a water supplement pipeline connected with the process water inlet 611. By adjusting the opening and closing of the twenty-sixth valve 612, the process water in the homogenizer 61 can be supplemented in time, so as to ensure the continuous and normal operation of the homogenizer 61.

[0059] In order to realize the switching of the three flow paths of the valve array system 100 faster, in the above embodiment, the valves used in the valve array group 3 are selected to be pneumatic butterfly valves. The relatively rapid opening and closing action of the pneumatic butterfly valves can meet the needs of the valve array system 100 for flexible conversion between multiple process modes, and avoid production interruption or material mixing deviation caused by slow valve action. In other embodiments, according to the actual application scene of the valve array system 100, other types of valves can be selected and applied in the valve array group 3, and multiple types of valves can also be combined for use, which is not limited here.

[0060] In other embodiments, the number of feed pipes in the valve array system 100 can also be redesigned according to the number of material types actually used in production and the requirements of various working conditions, so that the number of feed pipes reaches three or more, which is not specifically limited here.

[0061] The above merely describes the preferred embodiments of the present application, and is not used to limit the present application, and any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
