Description

Technical Field

[0001] The invention relates to the technical field related to grain polishing equipment, and in particular to a polishing device and a vertical environmentally friendly dust removal polishing machine. Background Art

[0002] The working principle of the polishing machine currently on the market is as follows: grain flows from the grain inlet into the kneading and polishing working area. The grain in the feed barrel of the working area is evenly spread to ensure the uniform flow of grain in the kneading and polishing area behind. The grain that enters the working area tangentially from the feeding bucket rubs against the components of the kneading and polishing system that are in a rotary motion. During this process, the grains also rub against each other, causing impurities on the surface of the grain to fall off and be polished. Since the kneading and polishing components are arranged at a specific angle and spacing, the grain is pushed toward the discharge port while being kneaded and polished. The kneaded and polished grain is discharged from the discharge port, and the dust and light impurities are extracted by the fan. Other impurities are discharged into the dust removal hopper through the screen and discharged from the impurity outlet.

[0003] Such a structure of equipment will cause the following problems:

[0004] 1. The grain has less friction with the polishing system components during the polishing process;

[0005] 2. The wind passes through a thick grain layer and cannot effectively and timely discharge the impurities produced after polishing;

[0006] 3. The polishing machine is not equipped with a dust removal system, resulting in a poor working environment. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a polishing device and a vertical environmentally friendly dust removal polishing machine, which can solve the problem of less contact between materials and polishing components and low polishing efficiency.

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] like Figure 1 , 2A polishing device shown includes a polishing machine cylinder 1, a dust cover 2 arranged on the upper part of the polishing machine cylinder 1, and a feeding flow pipe 3 arranged on the side wall of the dust cover 2. An upper polishing machine plate 4 and a lower polishing machine plate 5 for polishing materials are arranged in the upper part of the polishing machine cylinder 1. The upper polishing machine plate 4 is placed above and in contact with the lower polishing machine plate 5. A material receiving chute 6 is arranged below the lower polishing machine plate 5. A driving device for driving the upper polishing machine plate 4 to rotate is connected to the upper polishing machine plate 4.

[0036] like Figure 1 , 2 As shown, the top of the dust hood 2 is connected to a negative pressure dust collector, so that dust and impurities generated during the polishing process are sucked away by the negative pressure dust hood 2. The lower plate 5 of the polisher is fixedly connected to the mounting bracket arranged on the inner wall of the polisher cylinder 1 through the lower plate bracket 52, and the mounting bracket is connected to the lower plate bracket 52 through bolts. The longitudinal installation height of the lower plate 5 of the polisher can be adjusted by adjusting the bolts, thereby controlling the gap between the upper plate 4 of the polisher and the lower plate 5 of the polisher, achieving a better polishing effect, and reducing excessive wear of the polishing components.

[0037] like Figure 3 , 4 As shown, the upper plate 4 of the polishing machine includes a circular upper mounting plate 40 and a plurality of polishing components 41 mounted on the bottom surface of the upper mounting plate 40. A feed port 42 is provided on the top surface of the upper mounting plate 40, and a feeding bulk material plate 43 is provided below the feed port 42. The feeding bulk material plate 43 is located between the upper mounting plate 40 and the lower plate 5 of the polishing machine, and the feed port 42 is connected to the feeding flow grain pipe. A plurality of ventilation holes 45 are also provided on the upper mounting plate 40. A plurality of polishing components 41 are fixed on the upper mounting plate 40, which can significantly improve the polishing efficiency of the polishing device. The ventilation holes 45 are regularly distributed, so that the dust generated during polishing can be quickly discharged during the polishing process, and it is also beneficial to clean the polishing components 41.

[0038] like Figure 3 , 4 As shown in Figures 6 and 7, a mounting hole 44 is provided on the upper plate 4 of the polishing machine, and a polishing assembly 41 is mounted in the mounting hole 44. The polishing assembly 41 includes a U-shaped polishing assembly fixing plate 410 and a polishing cloth 411. The polishing cloth 411 is embedded in the polishing assembly fixing plate 410 and fixedly connected to the polishing assembly fixing plate 410, and the polishing assembly fixing plate 410 is fixedly connected to the upper mounting plate 40. The polishing cloth 411 can be made of cotton cloth or a brush. The polishing cloth 411 is embedded in the polishing assembly fixing plate 410 and fixedly connected, which can make the installation of the polishing cloth 411 more secure and prevent the polishing cloth 411 from being separated from the polishing assembly fixing plate 410 when it contacts the grain, thereby affecting the polishing efficiency.

[0039] like Figure 3 , 9As shown, a plurality of polishing assemblies 41 are evenly arranged on the bottom surface of the upper mounting plate 40, and the polishing cloth 411 is arranged at an angle with the radial direction of the upper mounting plate 40. The polishing cloth 411 arranged at an angle in the radial direction can form a better polishing angle with the lower plate 5 of the polishing machine, so that the polishing effect is better improved and the polishing efficiency is improved.

[0040] like Figure 3 , 4 As shown in Figures 5 and 6, the feeding bulk material tray 43 includes a mounting ring 430 and a material placing tray 431 connected to the mounting ring 430 through a support column 432. The support column 432 is evenly arranged around the mounting ring 430. The mounting ring 430 is aligned with the center of the feed port 42 and fixedly connected. The mounting ring 430 and the material placing tray 431 are fixedly supported by the support column 432, which can more effectively disperse the grain on the material placing tray 431 to the lower plate 5 of the polisher under the action of centrifugal force, thereby increasing the polishing efficiency.

[0041] like Figure 7 As shown, the lower plate 5 of the polishing machine includes a ventilation plate 50 and a rolling flat steel 51 uniformly arranged on the upper surface of the ventilation plate 50 in a radial direction. A lower plate bracket 52 is installed on the lower bottom surface of the ventilation plate 50, and the lower plate bracket 52 is connected to the inner wall of the polishing machine cylinder 1. The installation position of the lower plate bracket 52 can be adjusted by bolts to achieve the spacing between the upper and lower plates. Preferably, the ventilation plate 50 is a woven mesh ventilation plate, and a vortex guide track 53 is arranged on the upper surface of the ventilation plate 50. The use of a woven mesh form can better achieve the ventilation effect, and the negative pressure wind can better clean the dust and impurities on the surface of the grain in time. The rolling flat steel 51 fixed on the upper surface of the ventilation plate 50 can cooperate with the polishing assembly 41 when the upper plate 4 of the polishing machine is driven to rotate, so that the polishing assembly 41 polishes the outer surface of the grain at various angles, thereby increasing the polishing efficiency. The vortex guide track 53 can guide the grain that is radially dispersed around the upper plate 4 of the polisher, so that the grain in the middle circle part of the lower plate 5 of the polisher can be better dispersed in a vortex shape to the outer circle part of the lower plate 5 of the polisher, thereby extending the residence time of the material on the lower plate 5 of the polisher, achieving a better polishing effect, and finally falling to the edge of the lower plate 5 of the polisher.

[0042] like Figure 2 As shown, the receiving chute 6 is an annular groove inclined along the inner wall of the polishing machine barrel 1, and a discharge port 10 is provided on the side wall of the polishing machine barrel 1 corresponding to the lower side end of the receiving chute 6. The inclined receiving chute 6 can better send the grains falling from the polishing machine lower plate 5 after polishing to the discharge port 10 for collection.

[0043] like Figure 2As shown, the driving device includes a driving motor 8 arranged on the side wall or bottom wall of the polishing machine cylinder 1 and a transmission shaft 7 connected to the driving motor 8. The transmission shaft 7 passes through the polishing machine lower plate 5 and is fixedly connected to the bottom of the feeding bulk material plate 43 of the polishing machine upper plate 4.
