DETAILED DESCRIPTION

[0020] The following will be combined with the drawings of the specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1: Combination Figure 1-Figure 3 As shown, the utility model provides a technical solution: a heavy calcium carbonate slurry grading filter, comprising a box body 1, a feed hopper 2 is arranged on one side of the top of the box body 1, and its design takes into account both the smooth input of raw materials and the safety of operation. Through the feed hopper 2, the raw materials can enter the interior of the equipment conveniently and accurately, and prepare for the subsequent processing flow. A drum 3 is arranged on one side of the bottom of the feed hopper 2. The drum 3 is the core component of this equipment, and its rotational movement is the key to realizing slurry processing. A discharge assembly 6 and a driving member are arranged on both sides of the drum 3, respectively. The design of the discharge assembly 6 enables the processed raw materials to be discharged in an orderly manner, and the driving member provides continuous and stable power for the drum, ensuring the continuity and efficiency of the entire processing process. A knocking assembly 5 for knocking the drum 3 is arranged on one side of the feed hopper 2, and its function is to knock the drum 3. This knocking treatment not only helps the uniform discharge of the raw materials in the drum 3, but also prevents the raw materials from agglomerating or clogging in the drum 3 to a certain extent, thereby improving the processing effect and stability of the equipment;

[0022] The knocking assembly 5 includes a mounting plate 51 fixedly mounted on the box body 1. The mounting plate 51 serves as the basis of the entire knocking assembly. The mounting plate 51 is firmly mounted on the box body 1, which not only provides a mounting basis for other components, but also ensures the stability and reliability of the entire assembly. On the mounting plate 51, there is a sophisticated toggle member, which consists of a second motor 52, a rotating rod 53 and a toggle block 54. The second motor 52 is fixedly mounted on the mounting plate 51, and its output end is closely connected to the rotating rod 53. When the motor is started, the rotating rod 53 will rotate accordingly. The toggle blocks 54 are fixedly connected to the outer walls of the rotating rod 53 on both sides, and their positions correspond to the positions of the cross bar 56 to be introduced later.

[0023] The mounting plate 51 is provided with a lifting rod 55, which can be slidably installed along the mounting plate 51, and has cross bars 56 fixedly connected to both sides of its outer wall. The positions of these cross bars 56 match the positions of the toggle blocks 54. When the rotating rod 53 rotates, the toggle blocks 54 will toggle the cross bars 56, thereby driving the lifting rod 55 to move up and down.

[0024] Three groups of hammers 57 are fixedly connected to the lower end of the lifting rod 55. The positions of the three groups of hammers 57 correspond to the positions of the first filter cartridge 31, the second filter cartridge 32, and the third filter cartridge 33. When the lifting rod 55 is raised or lowered, the hammers 57 will move accordingly and knock the filter cartridges at appropriate positions.

[0025] At the upper end of the lifting rod 55, two limit blocks 58 are fixedly connected. The two limit blocks 58 are located between the mounting plates 51 and serve to limit the lifting range of the lifting rod 55. At the same time, a spring 59 sleeved on the lifting rod 55 is arranged between the two limit blocks 58. The spring 59 plays a role of buffering and resetting during the knocking process, ensuring that the knocking hammer 57 can knock the filter cartridge accurately and stably.

[0026] In the embodiment of the present invention, in modern industrial production, for the slurry screening process, technical innovation and optimization are particularly important. In order to effectively prevent the screened slurry from clogging the leakage hole, we designed an efficient knocking component 5. Through the carefully designed mechanical structure, the automatic knocking of the drum 3 is realized, thereby ensuring the smooth progress of the screening process;

[0027] The core part of the device is the introduction of the second motor 52. When the second motor 52 is started, it drives the rotating rod 53 to rotate. The rotating rod 53 is closely connected with the toggle block 54, so the toggle block 54 will also rotate synchronously with the rotation of the rotating rod 53. During the rotation process, the toggle block 54 will continuously toggle the crossbar 56, thereby triggering a series of exquisite chain reactions.

[0028] The cross bar 56 is closely connected with the lifting rod 55. When the cross bar 56 is moved by the moving block 54, it pushes the lifting rod 55 to move upward. During this process, the lifting rod 55 drives the striking hammer 57 and the limit block 58 to rise together. At the same time, the spring 59 is gradually compressed during the rising process of the lifting rod 55, accumulating elastic potential energy.

[0029] When the toggle block 54 continues to rotate until it is no longer in contact with the crossbar 56, the previously compressed spring 59 begins to release its stored elastic force. This release process drives the lifting rod 55, the knocking hammer 57 and the limit block 58 to move downward rapidly. At this moment, the three sets of knocking hammers 57 will quickly knock the first filter cartridge 31, the second filter cartridge 32 and the third filter cartridge 33, thereby achieving the knocking treatment of the filter cartridges.

[0030] The design of this knocking treatment mechanism cleverly avoids the problem of the slurry screened by the drum 3 blocking the leakage hole. In the actual production process, after the slurry is screened by the drum 3, the leakage hole may be blocked due to various reasons (such as high slurry viscosity, unreasonable leakage hole design, etc.). Long-term blockage will not only affect production efficiency, but also may cause equipment damage. By regularly knocking the filter drum, the blocked slurry can be effectively loosened and removed to ensure the smooth screening process.

[0031] It is worth mentioning that the design of the striking device fully considers the stability and durability of the mechanical structure. All components have been precisely processed and rigorously tested to ensure stable performance under long-term and high-intensity working conditions.

[0032] In short, by turning on the second motor 52 to drive the rotating rod 53 to drive the toggle block 54 to rotate synchronously, the device for knocking treatment is realized, which provides an effective solution for the slurry screening process. It not only improves production efficiency, but also reduces the risk of equipment damage, bringing tangible benefits to modern industrial production.

[0033] Embodiment 2: Combination Figure 2 As shown, on the basis of the first embodiment, the driving member 4 is the key part of the whole equipment, which is responsible for driving the rotation of the drum 3 to complete the filtering of the material. The driving member 4 mainly includes a first motor 41, which is fixedly mounted on the box body 1 to ensure its stability and reliability. The output end of the first motor 41 is fixedly connected to the rotating shaft 42, so that when the motor is started, the rotating shaft 42 will rotate accordingly;

[0034] The outer wall of the rotating shaft 42 is provided with a connecting frame 43, which not only plays the role of fixing the rotating drum 3, but also is responsible for transmitting the rotational power of the motor to the rotating drum 3. Through the well-designed connecting frame 43, the rotating drum 3 can rotate stably and smoothly, thereby achieving a filtering effect;

[0035] The drum 3 is the core part of the filtering system, which is composed of a first filter drum 31, a second filter drum 32, and a third filter drum 33. The three filter drums are fixedly connected by a connecting frame 43 to form a complete filtering unit. A feed port is provided at one end of the third filter drum 33 close to the first motor 41, so that the material can be conveniently entered from the bottom end of the feed hopper 2 to start the filtering process;

[0036] It is worth noting that the first filter cartridge 31, the second filter cartridge 32, and the third filter cartridge 33 are all provided with openings at one end away from the first motor 41, so that the filtered materials can be discharged from these openings, which is convenient for subsequent collection and processing. Among them, the surfaces of the third filter cartridge 33 and the second filter cartridge 32 are both provided with leakage holes, which are very cleverly designed. They can not only allow smaller material particles to pass through, but also prevent larger particles from entering the next filter cartridge to a certain extent, thereby achieving a multi-stage filtration effect;

[0037] In addition, the leakage hole of the third filter cartridge 33 is larger than that of the second filter cartridge 32, in order to better meet the filtering requirements of materials of different particle sizes. When it is necessary to filter materials with larger particles, the third filter cartridge 33 can be selected, and when it is necessary to filter materials with smaller particles, the second filter cartridge 32 can be selected. Such a design makes the whole filtering system more flexible and practical.

[0038] In addition, a sliding support 34 is rotatably arranged at the bottom of the first filter cylinder 31, and the sliding support 34 is fixedly mounted on the box body 1. This structural design allows the first filter cylinder 31 to rotate freely within a certain range, thereby reducing the friction and resistance caused by material accumulation and improving the filtration efficiency. At the same time, the use of the sliding support 34 also increases the stability of the entire rotating cylinder 3, ensuring the smooth progress of the filtration process.

[0039] In an embodiment of the present invention, the first motor 41 is turned on to drive the rotating shaft 42 and the connecting frame 43 to rotate synchronously, and the connecting frame 43 drives the first filter cartridge 31, the second filter cartridge 32, and the third filter cartridge 33 to rotate. The slurry in the third filter cartridge 33 is constantly rolling, and the slurry with smaller particles leaks into the second filter cartridge 32 through the leakage hole, and the slurry with larger particles remains in the third filter cartridge 33. The slurry in the second filter cartridge 32, the finer slurry will leak into the first filter cartridge 31. Finally, through continuous rolling, slurries of different sizes are discharged from different openings and the discharge assembly 6, respectively, to complete graded filtration.

[0040] Example 3: Combination Figure 2As shown, on the basis of the second embodiment, the core component of the discharge assembly 6 is a fixed seat 61 fixedly mounted on the box body 1. This fixed seat 61 is not only stable and reliable, but also plays an important supporting role for the entire discharge assembly 6. The bottom of the fixed seat 61 is cleverly fixedly connected with three groups of positioning frames 62. These three groups of positioning frames are rotatably connected with the first filter cartridge 31, the second filter cartridge 32, and the third filter cartridge 33 respectively.

[0041] This design of rotating connection enables the drum 3 to be easily rotated when material needs to be discharged, so as to conveniently introduce the filtered material into the next processing flow. At the same time, this design also ensures the stability and safety of the drum 3 during the rotation process, avoiding accidents caused by sudden breakage or falling off.

[0042] It is worth mentioning that the bottom of the three groups of positioning frames 62 are cleverly provided with discharge hoppers 63. These discharge hoppers 63 are not only reasonably shaped and can effectively collect and export the filtered materials, but also their positions and angles are carefully designed to ensure that the materials can flow smoothly into the designated collection container. This design not only improves work efficiency, but also greatly reduces the difficulty and error of manual operation.

[0043] In addition, the material selection and manufacturing process of the entire discharge assembly 6 have also been strictly screened and controlled. Whether it is the material of the fixed seat 61, or the manufacturing process of the positioning frame 62 and the discharge hopper 63, their durability and stability are fully guaranteed. This enables the discharge assembly 6 to always maintain its good working performance during long-term use, providing a strong guarantee for the smooth operation of the production line.

[0044] In the embodiment of the present invention, by continuously turning the first filter cartridge 31 , the second filter cartridge 32 , and the third filter cartridge 33 , slurries of different sizes are discharged from different openings and the positioning frame 62 and the discharge hopper 63 , respectively, to complete graded filtration.

[0045] Working principle of heavy calcium carbonate slurry grading filter:

[0046] Step 1: Put the slurry into the first filter cartridge 31 through the feed hopper 2, and start the first motor 41 to drive the rotating shaft 42 and the connecting frame 43 to rotate synchronously. The connecting frame 43 drives the first filter cartridge 31, the second filter cartridge 32, and the third filter cartridge 33 to rotate. The slurry in the third filter cartridge 33 keeps rolling, and the slurry with smaller particles leaks into the second filter cartridge 32 through the leak hole, and the slurry with larger particles remains in the third filter cartridge 33. The slurry in the second filter cartridge 32, the smaller slurry will leak into the first filter cartridge 31;

[0047] Step 2: Through the continuous turning of the first filter cartridge 31, the second filter cartridge 32, and the third filter cartridge 33, slurries of different sizes are discharged from different openings, the positioning frame 62, and the discharge hopper 63, respectively, to complete the graded filtration;

[0048] Step three, turn on the second motor 52 to drive the rotating rod 53 and the toggle block 54 to rotate synchronously. The toggle block 54 can toggle the cross bar 56 during the rotation process, thereby driving the lifting rod 55 to move upward. During the upward movement of the lifting rod 55, the knocking hammer 57 and the limit block 58 are driven to move upward and compress the spring 59. When the toggle block 54 rotates to no longer contact the cross bar 56, the lifting rod 55 and the knocking hammer 57 are driven downward by the elastic force of the spring 59, so that the three groups of knocking hammers 57 knock the first filter cartridge 31, the second filter cartridge 32, and the third filter cartridge 33 to prevent the slurry screened by the rotating drum 3 from clogging the leakage holes.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
