[0002] Continuous ball mill for high-fine grinding is mainly used for fine grinding and ultra-fine grinding of materials. It is widely used in mining, chemical, building materials, ceramics, coatings and other industries. Its main function is to grind larger particles of materials into smaller particles through the impact and friction of grinding balls to meet the particle size requirements of the product.

[0003] The existing continuous ball mill for high-fine grinding is usually composed of a chassis, a feeding and discharging mechanism, a driving mechanism and grinding balls.

Specifically:

[0014] 1. The cleaning bracket that rotates relative to the screening filter drives the cleaning brush and the vibration mechanism to rotate. The cleaning brush cleans the screening filter. The vibration mechanism vibrates as the screening filter rotates and transmits the vibration to the screening filter, thereby vibrating the screening filter.

With the cooperation of the supporting spring, the supporting sleeve slides back and forth. The reciprocating supporting sleeve acts on the screening filter, causing the screening filter to vibrate, thereby avoiding the clogging of the screening filter. The vibration of the screening filter can be driven without setting a power mechanism, thus saving energy consumption.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0033] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 With attached Figure 4 As shown, a continuous ball mill for high-fine grinding includes a chassis 1, wherein two ends of the chassis 1 are respectively connected to a feed port 11 and a discharge port 12, a power base 2 is rotatably connected to the chassis 1, a protective lining plate 7 is provided in the chassis 1, a screen partition plate 5 is provided in the chassis 1, a group of the screen partition plates 5 divides the chassis 1 into a coarse grinding area and a fine grinding area, the coarse grinding area and the fine grinding area of ​​the chassis 1 are both filled with grinding balls, the size of the grinding balls in the coarse grinding area is larger than that in the fine grinding area, another group of the screen partition plates 5 is arranged on the side of the chassis 1 close to the discharge port 12, a screening filter 6 is provided on the screen partition plate 5, a follower block 61 is rotatably provided on the side of the screening filter 6 close to the feed port 11, a cleaning mechanism 8 for cleaning the screening filter 6 and a counterweight mechanism 9 for keeping the cleaning mechanism 8 rotating relative to the screening filter 6 are provided on the follower block 61.

[0034] The chassis 1 is usually connected to a driving system, which usually includes a motor and a reducer. The chassis 1 is driven to rotate through a transmission device. This is the current existing technology and will not be described in detail here.

[0035] The power base 2 is provided with a feed box 3 on one side close to the feed port 11, and the feed box 3 is rotatably matched with the chassis 1. An air intake pipe 31 and a feed pipe 32 are connected on the feed box 3. The air intake pipe 31 is connected to an external air source providing mechanism, and the feed pipe 32 is connected to a material providing mechanism. The setting of the air intake pipe 31 increases the flow speed of the material in the chassis 1, further improves the grinding speed and effect of the material, and avoids over-grinding. At the same time, a protective lining plate 7 is fixedly connected to the chassis 1 by studs and bolts, and the inner side of the protective lining plate 7 is wavy. The protective lining plate 7 reduces the damage of the grinding balls to the chassis 1, and at the same time improves the transmission efficiency of the chassis 1 and the grinding balls.

[0036] The working principle of the present invention is as follows: the power base 2 provides a stable support for the chassis 1, and the driving system drives the chassis 1 to rotate on the power base 2. When the chassis 1 rotates, the chassis 1 drives the grinding balls to rotate. The grinding balls move along the chassis 1 under the action of centrifugal force and then fall under the action of gravity. This cycle continues. The material enters the chassis 1 through the feed port 11 through the feed pipe 32 under the action of the airflow of the air inlet pipe 31. The material entering the chassis 1 first contacts with the grinding balls moving in the coarse grinding area to achieve coarse grinding. When the size of the ground material is smaller than the size of the screening filter 6, the material enters the fine grinding area under the action of the airflow. Fine grinding is carried out in the grinding area. After the fine grinding is completed, the material flows out through the discharge port 12 with the air flow. Since the material can be fed and discharged continuously, the material can be continuously finely ground. In this process, when the screen partition plate 5 rotates, due to the setting of the counterweight mechanism 9, the center of the counterweight mechanism 9 and the cleaning mechanism 8 as a whole is lower than the position of the follower block 61, so that during the rotation of the screen partition plate 5, due to the effect of gravity, the cleaning mechanism 8 and the screen partition plate 5 and the screening filter 6 rotate relative to each other, and the cleaning mechanism 8 cleans the screening filter 6 to effectively avoid clogging of the screening filter 6.

[0037] Combined with Figure 3 , Attachment Figure 4 , Attachment Figure 5 With attached Figure 6 As shown, the cleaning mechanism 8 includes a cleaning bracket 81 arranged on the follower block 61, the cleaning bracket 81 is provided with a cleaning brush 85 that cooperates with the screening filter 6, the cleaning bracket 81 is slidably provided with a supporting slider 82, the cleaning bracket 81 is provided with a cleaning spring 84 connected to the supporting slider 82, and the supporting slider 82 is provided with a vibration mechanism 83 that vibrates as the screening filter 6 rotates.

[0038] Working principle of the cleaning brush 85: Since the cleaning bracket 81 and the follower block 61 rotate relative to each other, the cleaning bracket 81 and the screening filter 6 rotate relative to each other. The cleaning brush 85 arranged on the cleaning bracket 81 cleans the rotating screening filter 6, thereby avoiding clogging of the screening filter 6. During this process, the vibration mechanism 83 vibrates as the screening filter 6 rotates and acts on the screening filter 6, thereby avoiding clogging of the screening filter 6 by combining brushing and vibration, increasing the passing speed of the material, and avoiding over-grinding of the material. The setting of the cleaning spring 84 enables the vibration mechanism 83 to be reset when the grinding ball contacts the vibration mechanism 83.

[0039] Combined with Figure 5 , Attachment Figure 6 With attached Figure 7 As shown, the vibration mechanism 83 includes a telescopic rod 831 arranged on the supporting slider 82, a positioning frame 832 is provided at one end of the telescopic rod 831, a telescopic spring 833 connected to the positioning frame 832 is sleeved on the telescopic rod 831, a driving roller 8322 that is rotatably provided on the positioning frame 832 and is rotatably matched with the screen partition plate 5, a driving bevel gear 8323 is provided at the lower end of the driving roller 8322, a matching bevel gear 8321 that is meshed with the driving bevel gear 8323 is rotatably provided on the positioning frame 832, and a positioning frame 832 is provided on the positioning frame 832. A positioning sleeve 835 is provided with a supporting sleeve 837 which is slidably mounted on the positioning sleeve 835, a supporting plate 834 is provided on the positioning frame 832, a supporting spring 8341 which is connected to the supporting sleeve 837 is provided on the supporting plate 834, a rotating block 836 which drives the supporting sleeve 837 to slide back and forth along the positioning sleeve 835 is provided on the cooperating bevel gear 8321, a fixing column 8373 is symmetrically arranged in the supporting sleeve 837, and a spiral slide plate 8361 which is symmetrically arranged on the rotating block 836 and is in sliding contact with the fixing column 8373 is symmetrically arranged on the rotating block 836.

[0040] The working principle of the vibration mechanism 83: the telescopic spring 833 cooperates with the telescopic rod 831 to drive the positioning frame 832 to maintain a tendency to move toward the screen partition plate 5, the positioning frame 832 drives the driving roller 8322 to maintain contact with the screen partition plate 5, when the screen partition plate 5 rotates, the screen partition plate 5 drives the driving roller 8322 to rotate, the driving roller 8322 drives the driving bevel gear 8323 connected thereto to rotate, the driving bevel gear 8323 drives the mating bevel gear 8321 meshing therewith to rotate synchronously, the mating bevel gear 8321 drives the rotating block 836 to rotate, the rotating block 836 drives the spiral slide plate 8361 to rotate, and the spiral slide plate 8361 rotates. During the rotation process, the spiral slide plate 8361 drives the supporting sleeve 837 to slide along the positioning sleeve 835 toward the matching bevel tooth 8321 through the fixed column 8373. At this time, the supporting sleeve 837 squeezes the supporting spring 8341, and the supporting spring 8341 contracts under the force. As the rotating block 836 continues to rotate, the spiral slide plate 8361 is out of contact with the fixed column 8373. At this time, the supporting spring 8341 drives the supporting sleeve 837 to slide quickly and reset along the positioning sleeve 835, thereby hitting the screening filter 6, thereby causing the screening filter 6 to vibrate and avoid clogging of the screening filter 6.

[0041] Combined with Figure 5 , Attachment Figure 6 With attached Figure 7 As shown, a positioning groove 8351 is symmetrically provided on the inner side of the positioning sleeve 835, and a support rod 8372 is provided on the support sleeve 837. A support slider 8371 is slidably sleeved on the support rod 8372. The support slider 8371 is a rectangular structure. A supporting spring 8374 connected to the support slider 8371 is provided on the support rod 8372. Through the setting of the supporting spring 8374, the support slider 8371 maintains a sliding fit with the positioning groove 8351, thereby improving the stability of the sliding fit between the support sleeve 837 and the positioning sleeve 835.

[0042] Combined with Figure 4 , Attachment Figure 8 , Attachment Fig. 9 With attached Fig.10As shown, the counterweight mechanism 9 includes a counterweight bracket 91 arranged on the follower block 61, and a grab arm 92 is rotatably provided on the counterweight bracket 91. The grab arm 92 is equidistantly provided in at least three groups along the circumferential direction of the counterweight bracket 91. The counterweight bracket 91 is movably connected to a counterweight ball 93 through the grab arm 92. The counterweight bracket 91 is provided with a power mechanism for driving the grab arm 92. The power mechanism includes a counterweight connecting plate 911 and a supporting connecting plate 912 arranged on the counterweight bracket 91. The counterweight connecting plates 911 are equidistantly provided along the circumferential direction of the counterweight bracket 91. An operating through groove is provided between two adjacent groups of the counterweight connecting plates 911. A driving column 95 is rotatably provided on the supporting connecting plate 912. A driving hand wheel 951 is provided at one end of the driving column 95, and a driving stud 952 is provided at the other end of the driving column 95. A driving gear 921 meshing with the driving stud 952 is provided on the grab arm 92. A counterweight sliding column 9111 is provided on the counterweight connecting plate 911. The counterweight sliding column 9111 is slidably sleeved with a limiting sleeve 94. A limiting slide groove 941 is provided on the limiting sleeve 94. A limiting spring 942 connected to the limiting sleeve 94 is provided on the counterweight connecting plate 911. A limiting slide column 953 slidingly matched with the limiting slide groove 941 is provided on the driving hand wheel 951. A supporting support plate 9121 matching with the counterweight ball 93 is provided on the supporting connecting plate 912.

[0043] The working principle of the counterweight mechanism 9 is as follows: the limiting sleeve 94 is pushed away from the grab arm 92, the limiting sleeve 94 slides along the counterweight sliding column 9111 and squeezes the limiting spring 942, the limiting spring 942 is forced to shrink, and when the limiting sleeve 94 slides and separates from the limiting sliding column 953, the driving column 95 can rotate freely at this time, and the driving hand wheel 951 is turned, and the driving hand wheel 951 drives the driving stud 952 to rotate synchronously. When the driving stud 952 rotates, it drives multiple groups of grab arms 92 to open synchronously through the driving gear 921. At this time, the counterweight ball 93 can be taken out of or put into the grab arm 92, and then the driving hand wheel 951 is turned in the opposite direction, and the driving hand wheel 951 drives the driving stud 952 to rotate in the opposite direction. As the stud 952 rotates, it drives multiple groups of grab arms 92 to close synchronously through the driving gear 921. The grab arm 92 drives the counterweight ball 93 to abut against the support plate 9121 to limit the grab ball. After that, the limit sleeve 94 is loosened, and the limit spring 942 drives the limit sleeve 94 to slide along the counterweight slide column 9111 and slide into the limit slide column 953 to fix the position of the limit slide column 953, and further fix the counterweight ball 93. This structural setting can easily replace the counterweight ball 93 after it is worn. At the same time, the counterweight ball 93 of the corresponding composition can be replaced according to the composition of the material, so as to avoid the introduction of impurities during high-fine grinding and improve the quality of grinding.

The discharge mechanism 4 includes a discharge box 43 arranged on the power base 2, and the discharge box 43 is rotatably cooperated with the chassis 1. The two ends of the discharge box 43 are respectively connected with a discharge pipe 41 and an air outlet pipe 42, the discharge pipe 41 is connected with the material receiving mechanism, and the air outlet pipe 42 is connected with the gas recovery mechanism. An air outlet filter 421 is provided on the air outlet pipe 42, and a vibrating mechanism 44 is provided on the discharge box 43 for vibrating the discharge filter 13 as the discharge filter 13 rotates.

[0045] The working principle of the discharge mechanism 4 is as follows: the airflow drives the material to be ground by the grinding balls in the chassis 1, and the ground material is filtered by the discharge filter 13 and then enters the discharge box 43. The ground material falls under the action of gravity and flows out through the discharge pipe 41 to complete the grinding operation. The airflow is filtered again by the air outlet filter 421 and then flows out through the air outlet pipe 42 to avoid material loss. During this process, the vibration mechanism 44 vibrates the discharge filter 13 to avoid blockage of the discharge filter 13 and increase the discharge speed of the discharge filter 13.

During this process, the cleaning mechanism 8 cleans and vibrates the screening filter 6 through the brushing action of the cleaning brush 85 and the vibration action of the vibration mechanism 83, thereby preventing the screening filter 6 from being blocked. As the chassis 1 rotates, the discharge filter 13 rotates synchronously, and the rotating discharge filter 13 drives the vibration mechanism 44 to vibrate the discharge filter 13 to avoid blockage of the discharge filter 13. The material filtered by the discharge filter 13 flows out through the discharge pipe 41 under the action of gravity, and the airflow is filtered by the outlet filter 421 and then flows out through the outlet pipe 42, thereby completing the continuous high-fine grinding operation of the material.
