[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] During the long-term use of existing high-pressure roller mills, most of the crushed materials carry moisture or some viscous substances, which causes some materials to accumulate on the two rollers, resulting in a decline in the crushing effect. At the same time, it reduces the service life of the equipment and also reduces the working efficiency.

[0023] In view of this, the present invention provides a high-pressure roller mill with the function of removing accumulated materials. Through the cooperation among the hand wheel, worm, worm gear, material guiding plate and scraper, the worm gear rotates to a suitable angle. When the grinding roller rotates, the scraper rotates to a suitable angle, so that the tip of the scraper descends to the accumulated materials, realizing the cleaning and removal of the viscous substances accumulated on the grinding roller, and solving the problems that during the long-term use of existing high-pressure roller mills, most of the crushed materials carry moisture or some viscous substances, which causes some materials to accumulate on the two rollers, resulting in a decline in the crushing effect, and at the same time reducing the service life of the equipment and also reducing the working efficiency.

[0024] Through those skilled in the art, all the electrical components in this case are connected to their adapted power supplies through wires, and appropriate controllers and encoders should be selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, reference should be made to the sequence of the successive operations among the electrical components in the following working principle to complete the electrical connection. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of the electrical control will be made.

[0025] Example 1: As can be seen from Figure 1-5 , a high-pressure roller mill with the function of removing accumulated materials includes a box body 1, a box cover 2 is fitted to the top of the box body 1, a feed hopper 4 is provided on the top of the box cover 2, two fixing frames 11 are arranged inside the box body 1, a grinding roller 5 is rotatably connected to the inner wall of the fixing frame 11 through a bearing, and one of the grinding rollers 5 is electrically connected to a motor, so that the grinding roller 5 can rotate. Voltage transformation devices and other necessary electronic components should also be provided between the grinding roller 5 and the motor. This is the well-known prior art and will not be elaborated here. Thus, the staff pours the materials into the box body 1 from the feed hopper 4 and then grinds them through the grinding roller 5. A cleaning mechanism is arranged inside the box body 1. The cleaning mechanism includes a handwheel 6, a worm 7, a worm gear 8, a guiding plate 9 and a scraper 10. Guiding plates 9 are fixedly connected to both sides of the inner wall of the box body 1. A worm gear 8 is rotatably connected to one side of the guiding plate 9. The worm gear 8 is a half worm gear. A scraper 10 is fixedly connected to the bottom of the worm gear 8. A worm 7 is meshed with the top of the worm gear 8. The worm 7 passes through the inner wall of the box body 1 through a bearing and extends to the outside. A handwheel 6 is fixedly connected to one end of the worm 7 located outside the box body 1. It should be particularly noted that the guiding plate 9 not only plays a role in guiding the materials entering the box body 1, but also fixes the worm gear 8 while the worm 7 is also fixed to it through a bearing;

[0026] In the specific implementation process, it is particularly pointed out that the purpose of such a design is that when the staff rotates the handwheel 6, the worm 7 rotates. Since the worm 7 is meshed with the worm gear 8, the scraper 10 fixedly connected to the bottom of the worm gear 8 also rotates. Therefore, when the grinding roller 5 rotates, the scraper 10 at a certain angle can remove the accumulated materials on the grinding roller 5;

[0027] Furthermore, one of the fixing frames 11 is rotatably connected to the inner wall of the box body 1 through a bearing, and one side of the other fixing frame 11 is fixedly connected with a telescopic rod 12. It should be noted that the type of the telescopic rod 12 is not limited and can be an electric telescopic rod. The telescopic rod 12 adjusts its length, thereby adjusting the distance between the two grinding rollers 5 and adjusting the degree of material crushing according to the use requirements of the staff;

[0028] In the specific implementation process, it is particularly pointed out that the telescopic rod 12 can extend or retract, so that the distance between the two grinding rollers 5 is adjusted, and the particle size of the crushed materials is changed;

[0029] Furthermore, support legs 14 are fixedly connected to both sides of the bottom of the box body 1;

[0030] In the specific implementation process, it is particularly pointed out that the design of the support legs 14 serves the purpose of supporting the entire device and improves the stability of the high-pressure roller mill with the function of removing accumulated materials;

[0031] Furthermore, an anti-slip layer 15 is provided at the bottom of the support leg 14;

[0032] In the specific implementation process, it is particularly pointed out that the anti-slip layer 15 can be made of anti-slip materials such as rubber, which increases the friction between the support leg 14 and the ground, further improves the stability of the entire device, and prevents slipping during operation;

[0033] Furthermore, through grooves 16 are provided on both sides of the inner wall of the box body 1. The inner wall of the through groove 16 is rotatably connected to a lever 13 through a pin shaft. A plug rod 17 is fixedly connected to the top of the lever 13. The plug rod 17 is inserted into the side groove of the box cover 2. A first torsion spring 18 is fixedly connected to the inner wall of the through groove 16, and the other end of the first torsion spring 18 is fixedly connected to the inner wall of the box body 1;

[0034] In the specific implementation process, it is particularly pointed out that the staff presses the lever 13 at the bottom of the inner wall of the through grooves 16 on both sides of the box body 1, causing the lever 13 to rotate through the pin shaft, so that the plug rod 17 fixedly connected to the top of the lever 13 leaves the side groove of the box cover 2, enabling the box cover 2 to be separated from the box body 1. When the lever 13 is released, the lever 13 and the plug rod 17 are reset under the elastic force of the first torsion spring 18, reconnecting the box cover 2 to the box body 1;

[0035] Specifically, when using this high-pressure roller mill with the function of removing accumulated materials, when it is necessary to clean the accumulated materials on the grinding roller 5 of the device, the handwheels 6 on both sides of the box body 1 are rotated respectively, causing the worm 7 to rotate. Since the worm 7 is meshed with the worm gear 8, the scraper 10 fixedly connected to the bottom of the worm gear 8 also rotates to clean the accumulated materials on the rotating grinding roller. At the same time, the staff presses the levers 13 on both sides of the box body 1, causing the levers 13 to rotate through the pin shafts, so that the plug rods 17 leave the inner wall of the box cover 2, enabling the box cover 2 to be separated from the box body 1, and then tools can be used to quickly clean the accumulated materials on the scraper 10 or inside the box body 1.

[0036] Embodiment 2: As can be seen from Figure 1 、 2 and 6, cleaning agent bottles 19 are provided on both sides of the box body 1. A liquid injection port is installed at the top of the cleaning bottle 19 for filling cleaning agent. The bottom of the cleaning agent bottle 19 is connected to a round box 20. A blocking block 21 is rotatably connected to the inside of the round box 20 through a pin shaft. A handle 22 is fixedly connected to the outer wall of the blocking block 21. A second torsion spring 23 is installed between the handle 22 and the round box 20. The back of the second torsion spring 23 is fixedly connected to the blocking block 21. A drip tube 3 is inserted into the inner wall of the round box 20, and the drip tube 3 is inserted into the inner wall of the box body 1;

[0037] In the specific implementation process, it is particularly worth noting that in the normal state, the stopper 21 will block the cleaning agent bottle 19. When the staff rotates the handle 22, the stopper 21 rotates away from the mouth of the cleaning agent bottle 19, so that the internal cleaning agent is transported to the drip tube 3 through the round box 20, and then drips onto the grinding roller 5. When the staff releases the handle 22, the handle 22 is subjected to the elastic deformation force of the second torsion spring 23, and the handle 22 returns to its original position. Therefore, the stopper 21 also returns to its original position and blocks the mouth of the cleaning agent bottle 19 again;

[0038] Specifically, on the basis of the above-mentioned Embodiment 1, when cleaning the accumulated material, the staff rotates the handle 22, so that the stopper 21 fixedly connected to the handle 22 rotates away from the mouth of the cleaning agent bottle 19, so that the cleaning agent inside the cleaning agent bottle 19 is transported to the drip tube 3 through the round box 20, and then drips onto the grinding roller 5, so that the accumulated material on the grinding roller 5 can be better cleaned, improving the cleaning effect.
