Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material grinding, more particularly to a chemical material grinding machine. BACKGROUND

[0002] Grinding is one of the most important process steps in the processing of powder chemical materials, and through fine grinding, the particle size distribution of the powder chemical materials can be ensured to be uniform, which is crucial for maintaining the consistency and stability of the products. In the prior art, the chemical materials are usually crushed by a jaw crusher and then lifted to a bin by an elevator, and the chemical materials in the bin are continuously conveyed to a grinding machine by an electromagnetic vibrating feeder for grinding. The chemical materials are rolled and slid on the grinding ring by the rotating grinding roller, so that the grinding is realized by the cooperation of the grinding roller and the grinding ring. However, the above grinding process has certain defects: firstly, in the case of continuous feeding, the distribution of the chemical materials on the grinding ring is easy to be uneven, which causes the accumulation of materials in local areas and then causes uneven grinding. Although the rotation of the grinding roller can move the materials on the grinding ring, due to the uneven accumulation of the chemical materials and continuous feeding, the ability to automatically redistribute is limited, which will affect the grinding effect to some extent. In order to make up for the problem of uneven grinding, the equipment needs to run for a longer time, which increases energy consumption, and due to local overload, it will also aggravate the local wear of the grinding roller and the grinding ring.

[0003] Secondly, the contact area between the grinding roller and the grinding ring is limited, and only the crushing can be realized near the contact point. Moreover, due to the large gap between the particles of the material in the grinding mill and the small contact area between the particles, the friction force between the particles is small, the interaction force is weak, and the contact points are few, which further makes the grinding efficiency and grinding effect to be improved.

[0035] Referring to Figure 2 , Figure 4 , Figure 5 and Figure 6 , the annular surface of the upper half of the grinding cone 3013 is composed of a flow guide surface and a grinding surface, and there is a gap between the grinding cone 3013 and the inner wall of the grinding cylinder 2, so as to facilitate the outflow of the material after being ground, the pressing cone cover 3017 is slidingly connected with the inner wall of the grinding cylinder 2, the inner wall of the pressing cone cover 3017 is matched with the grinding surface of the grinding cone 3013, and the inner diameter of the connection between the feeding pipe 10 and the feeding hopper 6 and the outer diameter of the bottom end of the conical sealing plug 402 are the same.

[0036] Referring to Figure 2 , Figure 4 , Figure 5 and Figure 9The auxiliary discharging assembly comprises a cylinder 3031 fixedly installed at the top of the pressing cone cover 3017 and a reset plate 3033 fixedly installed at the top of the cylinder 3031 through a reset spring 3032, the lower end of the reset spring 3032 is fixedly connected with the top of the cylinder 3031, and the upper end is fixedly connected with the top of the reset plate 3033, the reset plate 3033 is fixedly installed with a reset rod 3034 slidingly penetrating the cylinder 3031 and the pressing cone cover 3017, the reset spring 3032 is sleeved outside the reset rod 3034, the inner wall of the pressing cone cover 3017 is provided with a containing groove 3035, the bottom end of the reset rod 3034 is fixedly installed with a soft brush 3036 slidingly connected with the containing groove 3035, the top of the soft brush 3036 is fixedly installed with two limiting plates 3037, one of which slidingly penetrates the pressing cone cover 3017, and the other is slidingly connected with the limiting groove provided in the inner wall of the pressing cone cover 3017, and the bottom of the pressing cone cover 3017 is fixedly installed with a sealing ring 3038 located in the gap between the grinding cone 3013 and the inner wall of the grinding cylinder 2 to block the gap.

[0037] In specific use, in the initial state, the conical sealing plug 402 is separated from the feeding pipe 10, and the pressing cone cover 3017 is separated from the grinding cone 3013, then the material is introduced into the feeding hopper 6, and the material falls into the gap between the grinding surface of the grinding cone 3013 and the inner wall of the pressing cone cover 3017 under the action of gravity, then the driving motor 3021 is started, the output shaft of the driving motor 3021 rotates to drive the driving bevel gear 3022 to rotate, the driving bevel gear 3022 is engaged with the driven bevel gear 3023, so that the grinding cone 3013 is rotated at high speed by rotating the rotating shaft I 3012, at the same time, the control assembly 502 controls the reciprocating assembly 501 to move up and down, so as to drive the conical sealing plug 402 to move synchronously through the L-shaped frame 401, and the pressing cone cover 3017 is driven to move synchronously through the L-shaped rod 3015 and the mounting sleeve 3016.

[0038] When the pressing cone cover 3017 is lowered, it will compress the material, making the material tightly compacted and spread on the grinding surface of the grinding cone 3013, at the same time, the soft hair brush 3036 is pressed against the grinding surface of the grinding cone 3013, and the sealing ring 3038 is inserted into the gap between the grinding cone 3013 and the inner wall of the grinding cylinder 2 to prevent the material from flowing out. After the material on the grinding surface of the grinding cone 3013 is compacted, the gap between the particles is reduced, increasing the contact area between the particles, making it easier for the particles to rub against each other. At this time, the material is in a compacted state, and the grinding cone 3013 rotates at high speed, causing the material particles on the grinding surface to be subjected to strong friction and shear force, and the material particles on the grinding surface will roll and slide with the rotation of the grinding cone 3013, causing the material particles to generate greater friction, thereby deeply grinding and refining the material. At the same time, the soft hair brush 3036 is pressed against the grinding surface of the grinding cone 3013 under the action of the counterforce of the stretched reset spring 3032, thereby continuously brushing off the material adhering to the grinding surface, preventing the material from adhering to the grinding surface under pressure. And the pressing cone cover 3017 will stay for a period of time after compacting the material, so that the material remains in a compressed state for a certain period of time and is continuously brushed off by the soft hair brush 3036 and then compacted, increasing the interaction time between the material particles, thereby ensuring that the material after each compaction has enough time to break, thereby improving the grinding effect and efficiency. At the same time, the conical sealing plug 402 also descends and plugs into the feed pipe 10, preventing the material from continuing to enter the feed pipe 10.

[0039] When the pressing cone cover 3017 rises, the material located at the high position of the grinding surface of the grinding cone 3013 will slide down to the low position under the action of gravity, and the material will experience redistribution during the sliding process, thereby helping to further crush the material, i.e., the intermittent lifting of the pressing cone cover 3017 can make the material redistribute after each compaction; each time the pressing cone cover 3017 descends, the material is compacted, and each time the pressing cone cover 3017 rises, the material is redistributed, and in this way of intermittent compaction, the material at different positions on the grinding surface can be fully ground, and each redistribution will make the material at different positions experience different friction, thereby improving the uniformity of grinding. At the same time, when the pressing cone cover 3017 rises, the sealing ring 3038 will be separated from the gap between the grinding cone 3013 and the inner wall of the grinding cylinder 2, and when the pressing cone cover 3017 rises, the soft brush 3036 will continue to abut against the grinding surface of the grinding cone 3013 under the action of the rebounding force of the return spring 3032, and at this time, as the grinding cone 3013 continues to rotate, the finely ground material will be separated from the grinding surface under the brushing of the soft brush 3036 and the action of gravity and flow out of the gap between the grinding cone 3013 and the inner wall of the grinding cylinder 2, and finally out of the discharge port 7. At the same time, when the pressing cone cover 3017 rises, the conical sealing plug 402 rises and separates from the feeding pipe 10, at this time, the feeding pipe 10 is opened, and the material can enter the feeding pipe 10 from the feeding hopper 6 and flow to the grinding surface of the grinding cone 3013.

[0040] Referring to Figure 1 , Figure 3 , Figure 7 and Figure 8 , the reciprocating assembly 501 further comprises a rotating disc 5011 and a track groove 5014 formed on the reciprocating block 5012, the track groove 5014 is composed of an arc segment and a horizontal segment connecting two ends of the arc segment, and the rotating disc 5011 is fixedly installed on the side close to the reciprocating block 5012 and is slidably connected with the track groove 5014.

[0041] Referring to Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 8 , the control assembly 502 comprises a control motor 5021 fixedly installed on the top of the grinding cylinder 2 and a mounting plate 5022, the mounting plate 5022 is fixedly installed on the side away from the control motor 5021 and is fixedly installed with a rotating shaft two 5023, the right rotating disc 5011 is fixedly installed on the right end of the rotating shaft two 5023, and the left rotating disc 5011 is fixedly installed on the left end of the output shaft of the control motor 5021.

[0042] Referring to Figure 1 , Figure 3 , Figure 7And Figure 8 The top of the grinding cylinder 2 is fixedly provided with two axis sleeves 5024 symmetrical to each other, and the two axis sleeves 5024 are jointly and rotatably provided with a rotating shaft three 5025. The output shaft of the control motor 5021 and the outer side of the rotating shaft two 5023 are both fixedly provided with a belt pulley one 5026. The outer side of the rotating shaft three 5025 is fixedly provided with two belt pulley twos 5027 symmetrical to each other. The belt pulley one 5026 and the corresponding belt pulley two 5027 are jointly and transmissionally connected with a belt 5028.

[0043] In specific use, the control motor 5021 is started, the output shaft of the control motor 5021 is rotated to drive the left rotating disc 5011 and the belt pulley one 5026 to rotate and drive the belt pulley two 5027 on the left to rotate through the left belt 5028, so as to drive the rotating shaft three 5025 to rotate, and then drive the rotating shaft two 5023 to rotate through the belt pulley two 5027 on the right, the right belt 5028 and the belt pulley one 5026 on the right, so as to drive the right rotating disc 5011 to rotate, and then make the two rotating discs 5011 rotate synchronously. The rotating disc 5011 drives the push rod 5013 to move along the track groove 5014. Figure 7 As shown in FIG. 5, when the push rod 5013 rotates counterclockwise along the arc segment of the track groove 5014 and upward, before moving to the connection between the arc segment and the horizontal segment, the track groove 5014 will not move upward because the center of the arc segment and the center of the rotating disc 5011 coincide. When the push rod 5013 moves to the connection between the arc segment and the horizontal segment and continues to rotate, the push rod 5013 starts to push the horizontal segment of the track groove 5014 to move upward, and then pushes the reciprocating block 5012 to drive the L-shaped frame 401 and the two L-shaped rods 3015 to move upward, so as to drive the conical sealing plug 402 and the pressing conical cover 3017 to move upward. When the push rod 5013 transitions from the horizontal segment to the arc segment, continuous pushing drives the reciprocating block 5012 to continue to move upward. At this time, the material enters from the feeding pipe 10 in the feeding hopper 6, and the material located at the high position of the grinding surface of the grinding cone 3013 will slide down to the low position under the action of gravity to be redistributed.

[0044] When the dial lever 5013 moves to the middle of the arc segment, continue to dial will push the reciprocating block 5012 to drive the L-shaped frame 401 and two L-shaped rods 3015 to move downward, thereby driving the conical sealing plug 402 and the pressing conical cover 3017 to move downward. When the dial lever 5013 transitions from the arc segment to another horizontal segment, continue to dial will continue to drive the reciprocating block 5012 to move downward, and the conical sealing plug 402 also descends with the reciprocating block 5012 and is inserted into the feed pipe 10, so that the material is blocked in the feed hopper 6 and prevented from continuing to enter the feed pipe 10. At the same time, when the pressing conical cover 3017 descends, it will press the material to make the material tightly compact and spread on the grinding surface of the grinding cone 3013. When the material is compacted on the grinding surface of the grinding cone 3013, when the dial lever 5013 transitions from the horizontal segment to the arc segment, the center of the rotating disc 5011 coincides with the center of the outer arc surface at this time. Continue to move the dial lever 5013 will not dial the reciprocating block 5012 to move. In this process, the pressing conical cover 3017 always keeps the material compacted, so that the material remains in a pressed state for a certain period of time, thereby increasing the interaction time between the material particles.

Based on the above description, other different forms of changes or variations can also be made by those of ordinary skill in the art.
