[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0037] Please also refer to Figures 1 to 2 The present invention is described below. A deagglomerator capable of removing fine powder in a gradient and low-energy manner comprises a feed unit 10, a grading unit, and a switching unit 30. The feed unit 10 comprises a feed pipe 101 for conveying material. The grading unit comprises a separation section 20 for separating material according to particle size. The separation sections 20 are at least three and are connected in series. A third valve is provided on the feed side of each separation section 20. The switching unit 30 comprises a plurality of bypass pipes 301 each connected to the feed pipe 101. A first valve 302 is installed on each bypass pipe 301. Material in the feed pipe 101 enters the grading unit through one of the bypass pipes 301.
[0038] Specifically, the first valve 302 is a gate valve.
[0039] Compared with the prior art, this embodiment provides:
[0040] 1. When the material passes through the grading unit, the opening and closing of the first valve 302 is controlled to allow the material to pass through different bypass pipes 301, thereby allowing the material to pass through different numbers of separation sections 20, thereby obtaining materials of different particle size segments; in actual production, different modes can be selected for discharging according to the final requirements for the material, thereby improving the applicability of the deagglomerator.
[0041] 2. There is no need to add an external grading structure separately, and energy consumption will not increase on the basis of grading, thereby saving energy and reducing production costs.
[0042] In some embodiments, see Figure 1 The feeding unit 10 includes a storage bin 102, a grinder 103 and a feeding auger 104. The storage bin 102 is used to receive materials delivered from the previous process; the grinder 103 has a grinding disc 1031 for crushing the materials, and a driving part for driving the grinding disc 1031. The discharge port of the grinder 103 is connected to the feeding pipe 101, and the grinding disc 1031 rotates around its own central axis; the feeding auger 104 is connected between the storage bin 102 and the grinder 103.
[0043] It should be noted that the previous step is the kettle coating step.
[0044] Specifically, the motor of the feeding auger 104 is frequency-controlled, and the feeding amount can be controlled by the frequency converter.
[0045] The material coming out of the coating kettle enters the storage bin 102. The material entering the storage bin 102 is crushed by the grinding disc 1031 and then enters the feed pipe 101 through the feed auger 104. The feed auger 104 continuously transports the material to the separation part 20 to ensure the continuity of the feed.
[0046] In some embodiments, see Figure 2 The driving part includes a first motor 1032 and a second motor 1033. The grinder 103 has a crushing area 1035 and a grading area 1036 located below the crushing area 1035. The grinding disc 1031 is installed in the crushing area 1035. The output shaft of the first motor 1032 is connected to the grinding disc 1031. A grading wheel 1034 is installed in the grading area 1036. The grading wheel 1034 rotates around its own central axis. The output shaft of the second motor 1033 is connected to the grading wheel 1034.
[0047] Specifically, the first motor 1032 and the second motor 1033 are both frequency-controlled, and the particle size of the material is controlled by adjusting the frequency converter.
[0048] Specifically, the grinder 103 also has a shell for covering the grinding disc 1031 and the classifying wheel 1034. The space on the upper part of the shell forms a classifying area 1036, and the space on the lower part of the shell forms a crushing area 1036. The second motor 1033 is installed on the top of the shell, and the output shaft of the second motor 1033 passes through the shell and is fixed to the classifying wheel 1034; the deagglomerator equipment that can remove fine powder in a gradient and low energy consumption also includes a base, and the shell and the first motor 1032 are fixed on the base, and the first motor 1032 and the grinding disc 1031 are driven by pulleys and belts.
[0049] When the first motor 1032 is activated, it drives the grinding disc 1031 via a pulley and belt. The second motor 1033 is activated, driving the classifying wheel 1034. The centrifugal force generated by the rotation of the classifying wheel 1034 separates the coarse and fine materials that have been transported by the rising airflow to the classification zone 1036. Fine particles that meet the required particle size pass through the classifying wheel 1034 and enter the feed pipe 101, while coarse particles descend to the crushing zone 1035 and are crushed by the grinding disc 1031. As a result, only materials that meet the required particle size pass through the classifying wheel 1034 and enter the feed pipe 101, improving production quality.
[0050] In some embodiments, see Figure 1 The deagglomerator equipment capable of removing fine powder with gradient and low energy consumption also includes a monitoring unit, which includes two level meters 40 and an alarm. The two level meters 40 are installed on the periphery of the storage bin 102 and distributed up and down. Both level meters 40 are communicatively connected to the alarm.
[0051] In some embodiments, two alarms are provided, and the two material level meters 40 are communicatively connected to the two alarms respectively.
[0052] Among them, when the top surface of the material in the storage bin 102 reaches or exceeds the material level meter 40 located at the top, the alarm connected to the material level meter 40 located at the top is activated and an alarm is sounded; when the top surface of the material in the storage bin 102 reaches or is lower than the material level meter 40 located at the bottom, the alarm connected to the material level meter 40 located at the bottom is activated and an alarm is sounded.
[0053] Specifically, the two alarms are both arranged in the power distribution room. The staff can know the approximate position of the material in the storage bin 102 by observing the two alarms in the power distribution room, thereby facilitating the staff to control the top surface of the material in the storage bin 102 to be between the two material level meters 40.
[0054] In some embodiments, see Figure 1 The storage bin 102 is provided with a breathing port 1021 which connects the interior of the storage bin 102 with the outside world, and a first filter element is installed in the breathing port 1021 .
[0055] After the material enters the storage bin 102 , the air in the storage bin 102 will be discharged through the breathing port 1021 . A first filter element is provided at the breathing port 1021 . The first filter element can filter the dust of the material, thereby reducing the dust content in the air discharged from the breathing port 1021 .
[0056] In some embodiments, see Figure 1 A vibrating hammer 1022 is installed at the bottom of the storage bin 102 . Specifically, two vibrating hammers 1022 are provided, and the two vibrating hammers 1022 are relatively arranged on both sides of the storage bin 102 .
[0057] After the materials enter the storage bin 102 , they may form an arch bridge or accumulate on the inner wall of the storage bin 102 due to accumulation. The different vibration frequencies of the vibrating hammer 1022 can be used to break the arch bridge and prevent the materials from hanging on the inner wall of the storage bin 102 .
[0058] In some embodiments, see Figure 1 The deagglomerator equipment capable of removing fine powder with gradient and low energy consumption also includes a power-assisting unit 50, which includes a power-assisting pipe 501 and a fan 502 arranged on the power-assisting pipe 501. The power-assisting pipe 501 is connected to the separation part 20 at the end. The fan 502 is provided to provide additional power to the movement of the material, so that the material moves smoothly in the pipe.
[0059] In some embodiments, see Figure 1 The separation section 20 at the end is a dust collector, and the remaining separation sections 20 are separators.
[0060] Specifically, a second valve 201 is installed at the discharge port of each separation part 20, a second silo 70 is detachable under the separation part 20 at the end, and a common first silo 60 is provided under the remaining separation parts 20, and the first silo 60 and the second silo 70 are connected.
[0061] Among them, when the number of separation parts 20 through which the material passes is at least two, the second silo 70 is removed and replaced with ton bags of material. At this time, the material in the first silo 60 is transferred to the next process; or the second silo 70 is not removed. At this time, the materials in the first silo 60 and the second silo 70 are combined and transferred to the next process.
[0062] In some embodiments, this embodiment is provided with three separation parts 20, the separation part 20 at the end is a pulse dust collector, the other two separation parts 20 are cyclone separators, and the second valve 201 is a discharge valve.
[0063] Mode 1: The material is discharged directly from the pulse dust collector without passing through the cyclone separator. This mode can achieve 100% yield, but the particle size distribution of this mode is wider.
[0064] Mode 2: The material passes through a cyclone separator and then a pulse dust collector. At this time, there are two ways of discharging the material. One is to enter the first silo 60 or the second silo 70 respectively. The materials in the first silo 60 and the second silo 70 are mixed and then discharged. The other is to remove the second silo 70 and replace it with a ton bag. The material is only discharged from the first silo 60, and the material in the ton bag is discarded. This mode has a lower yield than mode 1, but a narrower particle size distribution.
[0065] Mode 3: The material passes through two cyclone separators and then a pulse dust collector. At this time, there are two ways of discharging the material. One is to enter the first silo 60 or the second silo 70 respectively. The materials in the first silo 60 and the second silo 70 are mixed and then discharged. The other is to remove the second silo 70 and replace it with a ton bag. The material is only discharged from the first silo 60, and the material in the ton bag is discarded. The yield of this mode is between that of mode 1 and mode 2, and the particle size distribution is also between that of mode 1 and mode 2. This mode takes into account both quality and yield.
[0066] The granularity data tables for the three modes are as follows:
[0067]
[0068] Note: Dv(a) represents the particle size data value when the volume distribution accumulates to a%, and the unit of the particle size data value is μm; K value represents the width of the particle size distribution.
[0069] Specifically, a second filter element is installed in the pulse dust collector. The second filter element is a high-precision filter element. The second filter element can filter materials larger than 0.2μm, so that the emissions meet the standards.
[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
