Description

Technical Field

[0001] The utility model belongs to the technical field of heavy calcium carbonate processing, in particular to a grinding and collecting device for heavy calcium carbonate. Background Art

[0002] Heavy calcium carbonate, also known as heavy calcium carbonate, is a commonly used powdered inorganic filler made by grinding natural carbonate minerals such as calcite, marble, and limestone. It boasts high chemical purity, high inertness, resistance to chemical reactions, excellent thermal stability, resistance to decomposition below 400°C, high whiteness, low oil absorption, low refractive index, softness, dryness, absence of crystal water, low hardness and abrasiveness, and is non-toxic, tasteless, odorless, and highly dispersible. During processing, heavy calcium carbonate often requires grinding.

[0003] The Chinese utility model patent with announcement number CN218459654U discloses a grinding and collecting device for grinding heavy calcium carbonate, comprising a bottom support box, the top of the bottom support box is fixedly connected to a screening filter plate, the top of the screening filter plate is fixedly connected to a first grinding shell, the rear surface of the first grinding shell is fixedly connected to a driving box, the interior of the driving box and the interior of the first grinding shell are provided with a first grinding structure, the top of the bottom support box is fixedly connected to a bracket, the second grinding shell is fixedly connected between the opposite sides of the bracket, and the interior of the second grinding shell is provided with a second grinding structure; in the utility model, by arranging the first grinding structure and the second grinding structure at the top of the bottom support box, the heavy calcium carbonate added through the feeding port will enter the first grinding shell and be ground for the first time by the first grinding structure, and the ground heavy calcium carbonate enters the second grinding shell through the discharge channel and is ground for the second time by the second grinding structure, thereby achieving the effect of secondary grinding.

[0004] However, the above utility model still has some shortcomings:

[0005] During the use of the above-mentioned utility model, the heavy calcium carbonate powder and fine fragments that have undergone secondary grinding will fall on the screening filter plate. After filtering through the screening filter plate, the heavy calcium carbonate powder that meets the requirements will fall into the collection box, while the fine fragments that do not meet the requirements will accumulate on the screening filter plate, blocking the subsequent heavy calcium carbonate powder from passing through, affecting the collection of the heavy calcium carbonate powder. For this reason, it is necessary to clean the accumulation on the screening filter plate in time to ensure the normal collection of the heavy calcium carbonate powder. In addition, the screening filter plate is fixed in the connecting box. When the operator cleans the accumulation on the screening filter plate, it is necessary to use tools to reach into the connecting box to clean the accumulation, which is more troublesome.

[0028] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0029] See also Figure 1-4 The utility model provides a technical solution: a grinding and collecting device for heavy calcium carbonate, comprising a grinding box 1, a top cover 2 is provided on the top of the grinding box 1, a feed hopper 3 is provided on the top of the top cover 2, a crushing mechanism 4 and a grinding mechanism 5 are sequentially provided in the grinding box 1 from top to bottom, a moving component 7 is installed below the grinding mechanism 5, a filtering component 6 is connected to the moving component 7, and a storage box 8 is placed below the moving component 7 and at the inner bottom of the grinding box 1;

[0030] The movable assembly 7 includes a fixed frame 71, which is fixedly connected to the inner wall of the grinding box 1. Moving grooves 72 are provided on the left and right sides of the top of the fixed frame 71. Moving bars 73 are slidably arranged in the moving grooves 72. The tops of the two moving bars 73 are fixedly connected to a connecting frame 74, and the top of the connecting frame 74 is connected to the filter assembly 6.

[0031] Specifically, the heavy calcium carbonate fragments to be ground are poured into the grinding box 1 through the feed hopper 3, and firstly crushed into smaller fragments by the crushing mechanism 4. The small fragments are then ground into powder by the grinding mechanism 5. The heavy calcium carbonate powder falls on the filter component 6 for screening and filtration, and the screened powder falls into the storage box 8.

[0032] During the above grinding and filtering process, the fragments screened by the filtering component 6 remain on the screening net 61 . The operator can pull the moving component 7 to drive the filtering component 6 out of the grinding box 1 to clean the screening net 61 .

[0033] Furthermore, both the fixing frame 71 and the connecting frame 74 are in the shape of "冂", and the gaps of the fixing frame 71 and the connecting frame 74 face the front of the grinding box 1 directly.

[0034] Specifically, the length direction of the moving groove 72 is consistent with the width direction of the grinding box 1; a protective door 11 is provided on the front wall of the grinding box 1 corresponding to the positions where the filtering component 6, the moving component 7, and the storage box 8 are located, which facilitates the taking and placing of the storage box 8, and also facilitates the operator to pull the moving bar 73 and drive the filtering component 6 to slide on the fixing frame 71 through the connecting frame 74.

[0035] Furthermore, the filtering component 6 includes a screening net 61 that is inclined left and right. Connecting bars 62 are fixedly connected to both the left and right sides of the screening net 61. The bottom of the connecting bars 62 is connected to a connecting plate 64 through a plurality of telescopic cylinders 63, and a spring 65 is sleeved on the side wall of each telescopic cylinder 63.

[0036] Specifically, the base end of the telescopic cylinder 63 is fixedly connected to the top of the connecting plate 64, and its telescopic end is fixedly connected to the bottom of the connecting bar 62. The settings of the spring 65 and the telescopic cylinder 63 enable the screening net 61 to vibrate reciprocally in the vertical direction to accelerate the passing speed of the powder on the screening net 61, and at the same time enable the fragments remaining on the screening net 61 to accumulate along the inclined direction of the screening net 61 towards the side with a lower height, preventing the fragments from blocking the screening net 61 and affecting the screening effect.

[0037] Furthermore, the connecting plate 64 on the side with a lower height is fixedly connected to the top of the connecting frame 74, and the bottom of the connecting plate 64 on the side with a higher height is connected to the output end of a vibration motor 66. The vibration motor 66 is installed in a mounting seat 67, and the mounting seat 67 is fixedly connected to the top of the connecting frame 74.

[0038] Specifically, the output end of the vibration motor 66 drives the connecting plate 64 to vibrate in the vertical direction, causing the screening net 61 to vibrate under the action of the spring 65, accelerating the rolling of the fragments on the screening net 61 towards the side with a lower height to gather.

[0039] Furthermore, a channel opening 9 is provided on the side wall of the grinding box 1 at the position of the connecting plate 64 on the side with a lower height, and a collection box 10 is installed on the outer wall of the grinding box 1 outside the channel opening 9.

[0040] Specifically, the fragments remaining on the screening net 61 gather towards the position of the channel opening 9 under the action of the vibration motor 66, and the fragments enter the collection box 10 through the channel opening 9, ensuring that the screening net 61 can continuously filter the powder.

[0041] The working principle and use process of the utility model are as follows: After the utility model is installed, the heavy calcium carbonate fragments to be ground are poured into the grinding box 1 through the feed hopper 3. The heavy calcium carbonate fragments are first crushed into smaller fragments by the crushing mechanism 4. The small fragments are then ground into powder by the grinding mechanism 5. The heavy calcium carbonate powder falls on the screening net 61 and begins to be filtered;

[0042] During the filtration process, the vibration motor 66 drives the spring 65 and the telescopic cylinder 63 to vibrate in the vertical direction through the connecting plate 64, causing the screening mesh 61 to shake continuously, accelerating the powder filtration while causing the remaining fragments to roll toward the channel opening 9 and into the collection box 10, thereby avoiding obstruction of the screening mesh 61 in filtering the powder.

[0043] The filtered powder falls into the storage box 8. The operator can open the protective door 11 to take out the powder in the storage box 8. In addition, the operator can pull the connecting frame 74 outward to drive the screening net 61 to move outward, making it easier to clean the screening net 61.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
