Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of wet grinding, and in particular to a vibration grinding separation device and system. Background Art
[0002] Existing wet ball milling systems all need to separate the grinding balls and the ground materials. The separators mostly use a separation screen structure. Since the grinding balls and the ground materials will gather toward the separator during separation, it is easy to form blockage at the separation port of the separation screen, affecting the material separation efficiency.
[0003] Currently, there are two main methods for separating the grinding balls and the ground materials in the ball mill system. One is to fix the separation screen between the material outlet and the grinding chamber. The separation screen of this structure is in a fixed state when working. During the separation process, it is very easy to form aggregates on the surface of the separation screen and block the separation port. The other is to use centrifugal force to make the separator rotate at high speed. In this way, there will be no grinding balls or larger particles on the separator surface that will be blocked on the separation screen on the separator, affecting the separation. Its structure is complex and it is necessary to drive the separator to rotate. Summary of the Invention
[0004] The main technical problem solved by the present invention is to provide a vibration grinding separation device and system, wherein the vibration grinding separation device can avoid the formation of accumulation on the surface of the separation screen to block the separation port, thereby improving the separation efficiency and separation effect.
[0005] In order to solve the above problems, the present invention provides a vibration grinding and separation device, which includes a separator and a vibration mechanism for vibrating the separator.

A discharge port is also provided on the separator fixing seat, and the discharge port, the material hole, the separation inner cavity and the separation gap form a grinding material separation channel.
[0009] Furthermore, a shock absorbing mechanism is provided on the separator fixing seat.
[0010] Furthermore, the shock absorbing mechanism includes a first flange, a second flange, and a shock absorbing body arranged between the first flange and the second flange.

[0026] The following is a further description of the purpose, functional features and advantages of the present invention with reference to the embodiments and accompanying drawings. DETAILED DESCRIPTION
[0027] To make the purpose, technical solutions, and advantages of the invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0028] like Figure 1 As shown, the present invention provides an embodiment of a vibration grinding and separation device.
[0029] The vibration grinding and separation device comprises a separator 1 and a vibration mechanism 2 for causing the separator 1 to vibrate during the grinding process.
[0030] Specifically, the separator 1 is not the improvement point of the present invention, and its specific structure is not limited. As long as it can separate the grinding medium and the grinding material, the existing separation ring or mesh structure can be used. For the convenience of explanation, the separation ring is used as an example for this embodiment. The separator 1 is composed of a plurality of separation rings stacked together, and a separation gap is provided between two adjacent upper separation rings (not marked in the drawings). A separation cavity 11 is formed inside the separator 1 formed by the stacking of a plurality of separation rings. The separation gap connects the upper and inner sides of the separator 1, that is, connects the separation cavity 11 and the outside of the separator 1. The separator 1 is fixed on a separator fixing seat 4, and the fixing seat 4 is provided with a material hole 41 connected to the separation cavity 11. The fixing seat 4 is provided with a discharge port 3 connected to the material hole 41. The material port 3, the material hole 41, the separation cavity 11 and the separation gap form a grinding material separation channel.
[0031] The vibration mechanism 2 adopts existing technology, such as a vibrator driven by high-yield gas to generate vibration or an electrically driven vibrator, and the vibration intensity and frequency can be controlled. The vibration mechanism 2 is rigidly connected to the fixing base 4 and can also be rigidly connected to the separator 1.
[0032] During use, the vibration generated by the vibration mechanism 2 is rigidly transmitted to the separator 1, causing the separator 1 to vibrate at the same time, so that the separation gap on the separator 1 is blocked or the larger grinding materials and grinding media distributed around the separator 1 are separated from the separator 1, which can prevent the larger grinding materials and grinding media from clogging the separation gap of the separator and improve the smoothness of the discharge.
[0033] In order to reduce the vibration generated by the vibration mechanism from being transmitted to the grinding cylinder, Figure 2 As shown, a shock-absorbing mechanism 5 can be provided on the separator mounting base 4 to reduce the transmission of vibration to the grinding cylinder during operation. The shock-absorbing mechanism 5 includes a first flange 51 connected to the separator mounting base 41 and a second flange 52 connected to the grinding cylinder. A shock-absorbing body 50 is provided between the first flange 51 and the second flange 52. The shock-absorbing body 50 can be a shock-absorbing pad or a shock-absorbing spring. The shock-absorbing pad can be made of shock-absorbing rubber or an elastic bellows.
[0034] like Figure 3 As shown, the present invention further provides a grinding system, which includes a grinding cylinder 6 and a grinding and separating device. The grinding and separating device includes a separator 1 and a vibration mechanism 2 for causing the separator to vibrate during operation.
[0035] Specifically, the grinding system includes a grinding drum 6 with a feed inlet 12. A dispersion device is located within the grinding drum 6. The dispersion device includes a grinding shaft 7 and a disperser 8 mounted on the grinding shaft 7. A grinding and separation device is provided at the discharge. The grinding drum 6 is provided with a water cooling chamber 13 and a water inlet 10 and a water outlet 9 connected to the water cooling chamber 13.
[0036] Specifically, the separator 1 is not the improvement point of the present invention, and its specific structure is not limited. As long as it can separate the grinding medium and the grinding material, the existing separation ring or mesh structure can be used. For the convenience of explanation, the separation ring is used as an example for this embodiment. The separator 1 is composed of a plurality of separation rings stacked together, and a separation gap is provided between two adjacent upper separation rings (not marked in the drawings). A separation cavity 11 is formed inside the separator 1 formed by the stacking of a plurality of separation rings. The separation gap connects the upper and inner sides of the separator 1, that is, connects the separation cavity 11 and the outside of the separator 1. The separator 1 is fixed on a separator fixing seat 4, and the fixing seat 4 is provided with a material hole 41 connected to the separation cavity 11. The fixing seat 4 is provided with a discharge port 3 connected to the material hole 41. The material port 3, the material hole 41, the separation cavity 11 and the separation gap form a grinding material separation channel.
[0037] The vibration mechanism 2 adopts existing technology, such as a vibrator driven by high-yield gas to generate vibration or an electrically driven vibrator, and the vibration intensity and frequency can be controlled. The vibration mechanism 2 is rigidly connected to the fixing base 4 and can also be rigidly connected to the separator 1.
[0038] During use, the vibration generated by the vibration mechanism 2 is rigidly transmitted to the separator 1, causing the separator 1 to vibrate at the same time, so that the separation gap on the separator 1 is blocked or the larger grinding materials and grinding media distributed around the separator 1 are separated from the separator 1, which can prevent the larger grinding materials and grinding media from clogging the separation gap of the separator and improve the smoothness of the discharge.
[0039] In order to reduce the vibration generated by the vibration mechanism from being transmitted to the grinding cylinder, Figure 2 As shown, a shock-absorbing mechanism 5 can be provided on the separator mounting base 4 to reduce the transmission of vibration to the grinding cylinder during operation. The shock-absorbing mechanism 5 includes a first flange 51 connected to the separator mounting base 41 and a second flange 52 connected to the grinding cylinder. A shock-absorbing body 50 is provided between the first flange 51 and the second flange 52. The shock-absorbing body 50 can be a shock-absorbing pad or a shock-absorbing spring. The shock-absorbing pad can be made of shock-absorbing rubber or an elastic bellows.
[0040] like Figure 4 As shown, the present invention also provides another grinding system, which includes a disperser 8 and a grinding shaft 7 for fixing the disperser 8. The disperser 8 uses rod pins, which are evenly distributed on the surface of the grinding shaft 7. One end face of the grinding shaft 7 is provided with a cavity for accommodating a separator. The grinding cylinder 6 is also provided with a grinding medium delivery port. Other structures are the same as those in the above embodiment.
[0041] A square tooth structure 61, formed by grooves, is located on the inner surface of the grinding cylinder 6, specifically at the pin location. This structure increases the path of movement between the grinding material inlet 12 and the discharge port 3, thereby reducing the likelihood of grinding collisions and preventing grinding material from migrating from the gap between the pin structure and the inner wall of the grinding cylinder 6 to the discharge port 3. This could lead to a concentration of larger-diameter grinding material on one side of the discharge port 3, complicating discharge. Alternatively, a sealed clearance 71 is provided between the grinding shaft 7 and the disperser 8 to reduce the weight of the disperser 8 and alleviate the burden on the grinding shaft 7.
[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein, and these modifications and replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
