[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] In order to solve the technical problem of how to improve the homogenization and dispersion quality of materials, the utility model provides a homogenizing mixing and dispersing system, which can achieve the purpose of improving the homogenization and dispersion quality of materials.

[0030] It should be noted that the homogeneous mixing and dispersing system described in the present invention is used for but not limited to gypsum preparation, etc. For the convenience of explanation, in the present invention, only the application of the homogeneous mixing and dispersing system to gypsum preparation is used as an example for explanation, and the principle of applying the homogeneous mixing and dispersing system to other types of slurry production is essentially the same as the principle applied to gypsum preparation, which will not be repeated here.

[0031] See also Figure 1 , Figure 1This is a schematic diagram of the structure of a homogeneous mixing and dispersing system in an embodiment of the utility model. The homogeneous mixing and dispersing system includes a feeding part 1, a primary mixing part 2, a homogeneous dispersing part 3 and a discharging part 4. Through the cooperation of the feeding part 1, the primary mixing part 2 and the homogeneous dispersing part 3, after the materials are mixed, they are crushed to make the materials more refined and more uniform, thereby improving the homogenization effect. Among them, the feeding part 1 is used to feed the materials into the primary mixing part. Specifically, the primary mixing part 2 includes a first stirring device 21, which has a feed end and a discharge end, and the feed end is connected to the feeding part 1. After the raw materials are fed into the first stirring device 21, the raw materials are stirred to be fully mixed. After the materials are mixed, the homogeneous dispersion part 3 is provided with a feeding end and a discharging end, and the feeding end is connected to the discharging end of the first stirring device 21. The homogeneous dispersion part 3 includes a pulverizing unit 31 and a feeder 32. When the number of the pulverizing unit 31 and the feeder 32 are both one, they are connected head to tail in sequence to form a material flow line. When the number of any one of the pulverizing unit 31 and the feeder 32 is more than one, the pulverizing unit 31 and the feeder 32 are connected alternately in sequence to form a material flow line. The starting end and the end of the material flow line are the feeding end and the discharging end of the homogeneous dispersion part 3, respectively, for the materials to be supplied from the homogeneous dispersion part 3 to the material flow line. The materials enter the feeding end of the dispersed part 3, and pass through the alternately arranged pulverizer groups 31 and the feeder 32 in sequence, and then are discharged from the discharging end thereof. The mixed materials are crushed by the pulverizer group 31 to be refined and homogenized, and then connected to the feeder 32 to continuously and uniformly feed the subsequent materials. Multiple pulverizer groups 31 and multiple feeders 32 can be arranged alternately at intervals, first crushing and then feeding, then crushing and then feeding, to achieve a more refined homogenization effect, wherein the feeding end of the first pulverizer group 31 is the feeding end of the homogeneous dispersion part 3, and the discharging end of the last pulverizer group 31 or feeder 32 is the discharging end of the homogeneous dispersion part 3. The discharging part 4 is arranged at the discharging end of the homogeneous dispersion part 3, and is used to discharge the materials that have passed through multiple pulverizer groups 31 and multiple feeders 32, and guide them to the subsequent gypsum granulation link.

[0032] The pulverizer group 31 includes at least one pulverizer 311. When there are multiple pulverizers 311, the multiple pulverizers 311 are arranged in sequence from top to bottom to form a first-level or second-level or higher pulverization-type forced homogenization and dispersion.

[0033] In this embodiment, refer to Figure 1A crushing machine group 31 and a feeder 32 are used. After the first stirring device 21 in the primary mixing section 2 mixes the materials, the materials are crushed, and after crushing, the materials are continuously and evenly transported by the feeder 32. The first stirring device 21 is a low-speed mixer, and the crushing machine group 31 is composed of three crushers 311.

[0034] It can be understood that after stirring and mixing, crushing and feeding can further refine and homogenize the mixed materials, which can effectively improve the quality and consistency of the products.

[0035] Furthermore, the feeding part 1 includes a storage bin 11, an additive bin 12 and a water bin 13. The storage bin 11 and the additive bin 12 are respectively provided with a first feeding mechanism 14, and the water bin 13 is provided with a second feeding mechanism 15. The first feeding mechanism 14 includes a metering screw 141, one end of which is connected to the storage bin 11 or the additive bin 12, and the other end is connected to the feed end of the first stirring device 21. The powder and the additive are metered and transported by the metering screw 141. The second feeding mechanism 15 includes a water pipe 151 and a stop valve 152. The two ends of the water pipe 151 are respectively connected to the water bin 13 and the feed end of the first stirring device 21. The stop valve 152 is provided on the water pipe 151. The water supply is controlled by the timed stop valve 152 shutoff.

[0036] It is understandable that the additive and water may be mixed in a mixing chamber before being injected, or may be directly injected into the first stirring device 21 .

[0037] Furthermore, the discharging portion 4 includes a discharging conveyor belt 41 , and one end of the discharging conveyor belt 41 is connected to the discharging end of the homogeneous dispersion portion 3 .

[0038] In one embodiment, see Figure 2 Two crushing machine groups 31 and a feeder 32 are used. The feeder 32 is arranged between the two crushing machine groups 31. After the first crushing, the material is evenly transported by the feeder 32, and then the second crushing is performed, and intermittent crushing is performed. The first stirring device 21 is a low-speed mixer.

[0039] The first pulverizer group 31 includes two pulverizers 311 , and the second pulverizer group 31 includes one pulverizer 311 .

[0040] In this embodiment, the first crushing is performed after mixing, and then the material is uniformly fed to the second crushing, and finally discharged. Secondary crushing is performed first, and then primary crushing is performed. Fine crushing is performed first, and then a supplementary crushing is performed.

[0041] In one embodiment, see Figure 3 Two crushing machine groups 31 and a feeder 32 are used. The feeder 32 is arranged between the two crushing machine groups 31. After the first crushing, the material is evenly transported by the feeder 32, and then the second crushing is performed, and intermittent crushing is performed. The first stirring device 21 is a low-speed mixer.

[0042] The first pulverizer group 31 includes one pulverizer 311 , and the second pulverizer group 31 includes two pulverizers 311 .

[0043] In this embodiment, the first crushing is performed after mixing, and then the material is uniformly fed to the second crushing before being discharged. The first crushing is performed first, and then the second crushing is performed. The material is first coarsely crushed and finally finely crushed before being discharged.

[0044] In one embodiment, see Figure 6 A crushing machine group 31 and a feeder 32 are used. After the first stirring device 21 in the primary mixing section 2 mixes the materials, the materials are crushed, and after crushing, the materials are continuously and evenly transported by the feeder 32. The first stirring device 21 is a high-speed mixer, and the crushing machine group 31 is composed of three crushers 311.

[0045] Understandably, compared to Figure 1 The low-speed mixer solution shown in the figure has a faster mixing rate and takes less time to mix.

[0046] It should be noted that the low-speed mixer and the high-speed mixer can respectively adopt the existing concrete mixer and the existing vertical-shaft planetary mixer, which can meet the requirements of low-speed mixing and high-speed mixing. According to the different homogeneous quality requirements of the materials, the corresponding mixing and crushing combination can be selected. Among them, the crusher can also adopt the existing material crusher, which can crush the gypsum mixed materials.

[0047] In one embodiment, see Figure 4 In order to further improve the homogeneous mixing effect, the system also includes a secondary mixing section 5, which includes a second stirring device 51. The second stirring device 51 is inserted between any of the feeders 32 and the pulverizer group 31. The second stirring device 51 has a feeding end and a discharging end. The feeding end is connected to the adjacent pulverizer group 31, and the discharging end is connected to the feeder 32 for secondary mixing of materials. The secondary mixing can be used to add other materials for mixing, or the material can be directly mixed for the secondary mixing to improve its homogeneous mixing degree and make the components in the material more evenly distributed.

[0048] The feeding section 1 is also arranged on the secondary mixing section 5 , with another material storage bin being used to feed other materials into the second stirring device 51 .

[0049] In this embodiment, a pulverizing unit 31 and a feeder 32 are used, and a first stirring device 21 and a second stirring device 51 are also used. Among them, the first stirring device 21 and the second stirring device 51 both use low-speed mixers, and the pulverizing unit 31 uses two pulverizers 311. Through low-speed mixing and pulverizing combined with low-speed mixing, a better homogenization effect is obtained.

[0050] In one embodiment, see Figure 5 , a pulverizing unit 31 and a feeder 32 are used, and a first stirring device 21 and a second stirring device 51 are also used. Among them, the first stirring device 21 adopts a low-speed mixer, the pulverizing unit 31 adopts two pulverizers 311, and the second stirring device 51 adopts a high-speed mixer. Through low-speed mixing and pulverizing combined with high-speed mixing, a better homogenization effect can be obtained.

[0051] In one embodiment, see Figure 7 The feeder 32 includes a material box 321, a feeding conveyor belt 322 and a stirring rod 323. The top and bottom of the material box 321 are both provided with openings 301. The feeding conveyor belt 322 is arranged flatly on the bottom of the material box 321 and covers the opening 301 at the bottom of the material box 321. A discharge port 302 is opened on one side of the material box 321. The discharge port 302 is connected to the opening 301 at the bottom of the material box 321, and the stirring rod 323 is arranged at the discharge port 302. The stirring rod 323 is driven by a motor to stir the material at the discharge port 302 to avoid blockage.

[0052] It can be understood that the material is put into the top of the material box 321, transported along the feeding conveyor belt 322, and finally discharged from the discharge port 302, and is broken up by the stirring rod 323 at the discharge position to achieve the purpose of uniform feeding.

[0053] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the utility model is described in detail: the feeding section 1 stores raw materials and supplies them to the primary mixing section 2, which is stirred and mixed in the first stirring device 21. After stirring and mixing, the raw materials are transported to the homogenizing and dispersing section 3. The homogenizing and dispersing section 3 forces the materials to be homogenized and dispersed by the pulverizing unit 31, and a secondary mixing section 5 can be provided between the pulverizing unit 31 and the feeder 32 to perform secondary mixing of other materials. Secondary mixing can also be performed directly to improve the homogenization and dispersion quality.

[0054] It should be noted that when the mixing, crushing and feeding equipment are arranged horizontally at intervals, a conveyor belt is used to connect the discharge end of the previous equipment with the feed end of the next equipment to feed the materials.
