[0036] A separation shielding ring 301 is fixedly provided on the outer bracket body 3, and the separation shielding ring 301 is sleeved on the outside of the rotating grinding disc 2. A pulley 701 is fixedly provided on the wheat input pipe 7, and the pulley 701 drives the wheat input pipe 7 and the rotating grinding disc 2 to rotate.
[0037] An anti-tilting plate 601 is fixedly provided on the surface of the central rotating sleeve 6 , and a holding ball 602 is provided below the anti-tilting plate 601 . The anti-tilting plate 601 is in limited contact with the upper surface of the rotating grinding disc 2 through the holding ball 602 .
[0038] A highly adaptable grinding mill system comprises a grinding mill device, an online particle size analyzer and a central control system. The online particle size analyzer comprises a detection probe, a signal processing system and a data transmission system. The principle is that scattering and diffraction phenomena occur when laser is irradiated on particles. The intensity of the diffraction and scattered light is related to the size of the particles. By observing the light intensity, the Fraunhofer diffraction theory and the Mie scattering theory can be applied to obtain the particle size distribution, so as to obtain the scraping rate of the material. The material ground by the grinding mill device is tested for the scraping rate by the online particle size analyzer, and the test result is input into the central control system.
[0039] The central control system is mainly composed of PLC modules, which can realize data comparison, servo motor control and other functions through programming. The central control system compares the test results with the set target scraping rate, and controls the grinding mill device according to the comparison results, adjusting the distance between the fixed grinding disc 1 and the rotating grinding disc 2 until the detected scraping rate is consistent with the target scraping rate within the allowable error.
[0040] When in use, the grinding mill device of the present invention is fixedly installed in the grinding mill through the external bracket body 3, and the separation of the upper and lower parts is achieved by cooperating with the grinding mill through the separation ring 301. The pulley 701 is connected to the driving device in the grinding mill through a belt, and the synchronous worm 10 is installed with the servo motor for transmission, and the synchronous worm 10 is controlled by the servo motor to rotate precisely.
[0041] During the grinding process, the wheat input pipe 7 and the rotating grinding disc 2 are driven to rotate by the pulley 701. At this time, the fixed grinding disc 1 is in a fixed state, and the rotating grinding disc 2 rotates relative to the fixed grinding disc 1. The wheat is input through the wheat input pipe 7. Figure 7 As shown in the figure, when wheat is input, the weight of the wheat will push down and open the conical plug 222, and it will enter between the fixed grinding disc 1 and the rotating grinding disc 2. Radial grooves are provided on the surface between the fixed grinding disc 1 and the rotating grinding disc 2. The wheat is crushed between the fixed grinding disc 1 and the rotating grinding disc 2, and moves radially outward by the rotating centrifugal force.
[0042] The material ground by the grinding mill is tested for scraping rate through an online particle size analyzer, and the test result is input into the central control system, which compares the test result with the set target scraping rate. When it is necessary to adjust the distance between the fixed grinding disc 1 and the rotating grinding disc 2, the synchronous worm 10 is controlled by the servo motor to rotate, and the synchronous worm 10 drives the worm wheel 9 to rotate, so that the adjusting stud 8 rotates. At this time, the adjusting studs 8 on both sides rotate synchronously. By setting the thread direction of the two groups of adjusting studs 8, the two groups of adjusting studs 8 drive the corresponding adjusting end seats 4 to move up and down synchronously.
[0043] When the adjustment end seat 4 moves up and down, the wheat input pipe 7 and the rotating grinding disc 2 can be driven to rise and fall through the support arm bridge 5 and the center rotating sleeve 6 to achieve spacing control.
[0044] In order to avoid a rapid temperature rise during the grinding process, the fixed grinding disc 1 and the rotating grinding disc 2 are usually thick grinding disc structures. Therefore, the rotating grinding disc 2 has a large inertia during the rotation process. When the grinding is completed and the control equipment is shut down, the inertia of the rotating grinding disc 2 will drive the external equipment to rotate. When the external motor and other equipment used to drive the rotating grinding disc 2 are dragged to rotate, an induced electromotive force will be generated inside, causing components such as the frequency converter to be affected, and transmission components such as the pulley 701 will also suffer certain losses.
[0045] When the grinding is completed and the control device is stopped, Figure 8 As shown in , the electromagnet module 211 is energized at the same time, so that the electromagnet module 211 generates magnetic force, attracts the suspension plate 207 to move downward, drives the dynamic gear 202 to move downward, and makes the dynamic gear 202 mesh with the brake gear ring 201. At this time, the split turntable 205 is driven to rotate, and the air pump cylinder 214 is driven to operate through the movable connecting rod 213; the rotation resistance of the dynamic gear 202 will curb the rotation of the rotating grinding disc 2, and reduce the number of rotations of the rotating grinding disc 2 due to inertia. At the same time, the compressed gas generated by the air pump cylinder 214 is input into the high-pressure gas cylinder 216 for storage.
[0046] After a certain delay, the control valve 217 is opened to release the compressed gas in the high pressure gas cylinder 216 into the input gas pipe 218. Figure 7 As shown in the figure, the compressed gas enters the jet chute 220 through the annular gas groove 219 and is sprayed into the interior of the wheat input pipe 7. At this time, due to the cooperation between the conical plug 222 and the inner wall retaining ring 221, the upper part of the wheat input pipe 7 is closed, so the gas enters between the fixed grinding disc 1 and the rotating grinding disc 2, and the residual wheat fragments between the fixed grinding disc 1 and the rotating grinding disc 2 are blown out, thereby realizing automatic cleaning of the device and avoiding the hygienic problems such as mildew of the residual wheat fragments during long-term shutdown.
[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
