Description

Technical Field

[0001] This invention relates to the field of filter technology, specifically to an automatically compensated floating filter. Background Technology

[0002] Vertical wet grinding equipment is the core equipment for the fine processing of materials. It is widely used in chemical, coating, pharmaceutical, and new material fields. It mainly achieves ultra-fine grinding and refining of materials through the full collision and shearing between the grinding media and the materials. With the addition of a filter structure, it can complete the separation of coarse and fine materials and ensure the uniformity of particle size of the finished material. Currently, existing vertical wet grinding equipment has many technical defects in practical applications, which restrict the accuracy of material grinding and the stability of equipment operation. 1. The connection between the rotating shaft of the equipment and the filter structure, end plate, and end cover mostly adopts a fixed sealing structure. During the grinding operation, the equipment vibrates continuously and the parts wear slightly, which can easily lead to gaps in the sealing structure, causing problems such as material leakage and grinding fluid leakage. This not only wastes materials, but also affects the internal pressure stability of the grinding chamber and reduces the grinding quality of the materials. After wear, the seals need to be frequently inspected and replaced manually, resulting in a high frequency of equipment downtime for maintenance and a significant reduction in continuous production efficiency. 2. Conventional grinding equipment's sealing structure is mostly a single elastic support structure. Under high-speed rotating grinding conditions, the sealing components are prone to displacement due to the combined effects of centrifugal force, material impact, and equipment vibration, resulting in a significant decrease in sealing reliability and making it difficult to meet the needs of long-term, high-load wet grinding operations. Summary of the Invention

[0003] The purpose of this invention is to provide an automatically compensated floating filter to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatically compensated floating filter, comprising a base and a grinding cylinder, wherein the grinding cylinder is fixed on the base and a feed inlet is provided at the lower end of the grinding cylinder, a fixing box is fixed at the upper end of the grinding cylinder, an end cap is fixed at the upper end of the fixing box, and a liquid pipe is provided on the side of the fixing box, a rotating shaft driven by a motor is provided inside the grinding cylinder, a stirring impeller with discharge blades is fixed on the rotating shaft, a filtering mechanism is fixed on the grinding cylinder, an automatically compensated sealing assembly is provided between the filtering mechanism and the rotating shaft, an adjusting assembly is also installed on the rotating shaft for initial adjustment of the sealing assembly, and a self-locking assembly is also installed on the sealing assembly, which can achieve automatic locking of the sealing assembly under the action of rotation and centrifugal force.

[0005] Preferably, a cooling jacket is provided on the outside of the grinding cylinder, and a cooling cavity is formed between the cooling jacket and the grinding cylinder. A water inlet is installed at the lower end of the cooling jacket, and a water outlet is installed at the upper end of the cooling jacket. Through the cooling cavity formed between the cooling jacket and the grinding cylinder, in conjunction with the functions of the water inlet and the water outlet, the cooling water can be easily circulated in the cooling cavity, thereby ensuring the normal operation of the device.

[0006] Preferably, the filtration mechanism includes a filter cylinder nested within the grinding cylinder, with lower filter holes evenly distributed on the lower end face of the filter cylinder, and an end plate installed on the upper end of the filter cylinder, with upper filter holes evenly distributed on the end plate. The filter cylinder and the end plate are locked to the grinding cylinder by bolts, and sealing components are provided between the filter cylinder, the end plate, and the rotating shaft. Through the action of the lower and upper filter holes, the grinding media balls can be discharged, ensuring the normal operation of the device.

[0007] Preferably, the sealing assembly includes a positioning ring fixed to the rotating shaft, and an elastic sealing ring is nested inside the positioning ring. The sealing ring is also fixed with locking blocks at equal angles, and the locking blocks are engaged with the positioning ring. Through the engaging action between the locking blocks and the positioning ring, the position of the sealing ring and the positioning ring can be limited, thereby ensuring the normal operation of the device.

[0008] Preferably, two sets of first inclined ring plates are fixed inside the sealing ring, and the first inclined ring plate and the second inclined ring plate are slidably connected. A bracket is fixed inside the second inclined ring plate, and the bracket is slidably connected to the positioning ring and the rotating shaft. The bracket drives the second inclined ring plate to move. With the sliding action between the second inclined ring plate and the first inclined ring plate, the sealing ring can expand outward evenly, thereby achieving automatic sealing compensation. This avoids the sealing ring from being worn due to contact with the filter cylinder and end plate, which affects the sealing effect and better meets the actual use requirements.

[0009] Preferably, a vertical rod is fixed to the lower end of the bracket, and the vertical rod is slidably connected to the fixed plate. The fixed plate is fixed inside the rotating shaft, and a first spring is also fixed between the vertical rod and the fixed plate. The first spring provides a pre-tightening force to the vertical rod. When the bracket moves, the sliding guide between the vertical rod and the fixed plate can ensure the stability of the bracket's movement. Furthermore, the elasticity of the first spring can provide a basic force for the automatic reset of the vertical rod, thereby providing a basic guarantee for the floating control compensation of the device and ensuring the normal operation of the device.

[0010] Preferably, the adjustment component includes a movable ring that is slidably connected to the rotating shaft, and a slide rod is fixed inside the movable ring. The slide rod is slidably connected to the rotating shaft. Through the sliding action between the movable ring and the rotating shaft, the slide rod can be driven to move along the axial direction of the rotating shaft, thereby providing a basic guarantee for the adjustment of the sealing component. Furthermore, through the sliding guiding action between the slide rod and the rotating shaft, the stability of the movable ring's movement relative to the rotating shaft can be ensured.

[0011] Preferably, one end of the sliding rod and one end of the round rod are fixed to each other, and the round rod and the vertical rod are slidably connected. A second spring is fixed between the other end of the round rod and the rotating shaft. At the same time, a pressure plate is fixed on the round rod. The pressure plate and the bracket are distributed in a one-to-one correspondence. When the sliding rod moves, it can drive the pressure plate to move synchronously. The pressure plate applies force through contact with the bracket, which can provide a basic guarantee for the movement of the bracket, thereby providing a basic guarantee for the initial pre-tension of the first spring, and thus ensuring the normal operation of the device. Through the elastic action of the second spring, it can provide a basic force for the automatic reset of the round rod, thereby ensuring the normal operation of the device.

[0012] Preferably, the self-locking assembly includes a mounting plate fixed to the lower end of the vertical rod, and a support plate fixed to the lower end face of the mounting plate. A crossbar is slidably connected to the support plate, and a counterweight is fixed to one end of the crossbar. A third spring is fixed between the counterweight and the support plate. The mounting plate is rotated by a rotating shaft. Combined with the centrifugal force of the counterweight, the counterweight can be moved. The sliding guide between the crossbar and the support plate ensures the stability of the counterweight's movement. The elasticity of the third spring provides a basic guarantee for the automatic reset of the counterweight, thereby ensuring the normal operation of the device.

[0013] Preferably, a toothed block is fixed to the other end of the crossbar, and the toothed block and the toothed ring plate cooperate to form a locking mechanism. The toothed ring plate is fixed inside the rotating shaft, and the toothed ring plate and the rotating shaft are distributed in a one-to-one correspondence. When the crossbar slides, it synchronously drives the toothed block to move towards the toothed ring plate. With the locking action between the toothed block and the toothed ring plate, the locking function of the device can be realized, thereby realizing the locking function of the sealing component and preventing the sealing component from loosening due to vibration or other factors when the rotating shaft rotates, thus affecting the sealing performance of the device.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This automatically compensated floating filter is equipped with an elastic sealing component. The sealing ring is fixed by a positioning ring, and the first spring provides a stable pre-tightening force for the vertical rod, bracket and inclined ring plate structure. When the equipment is stationary and not working, the sealing component is in a flexible support state. It can automatically fine-tune the fit according to the gap of the contact surface, so that the sealing ring is always tightly fitted with the filter cylinder, end plate and end cover. It effectively compensates for the sealing defects caused by slight wear of sealing components and assembly gaps, eliminates static leakage and material leakage problems, eliminates the need for frequent replacement of sealing components, and reduces equipment operation and maintenance costs. 2. This automatically compensated floating filter is equipped with a centrifugal self-locking component. During high-speed grinding operations, the rotating shaft drives the counterweight to generate centrifugal force, which drives the crossbar to slide and engages the toothed block with the toothed ring plate, converting the flexible support sealing structure into a rigid fixed state. This effectively avoids the problems of sealing structure displacement and loosening caused by mechanical vibration and material fluid impact during equipment operation, completely solving the defects of sealing failure under dynamic working conditions, ensuring the sealing integrity of the grinding chamber throughout the process, stabilizing the internal working pressure of the chamber, and providing a basic guarantee for the precise grinding of materials. 3. This automatically compensated floating filter achieves precise initial control of the sealing components through adjustment components. Relying on the linkage structure of the moving ring, slide bar, round rod and spring, it can adjust the pre-tightening force of the sealing structure to adapt to different working requirements. At the same time, it can achieve adaptive switching between static flexible compensation and working rigid locking. The two states are seamlessly connected, which not only retains the adaptability of automatic compensation sealing, but also has the structural stability of the working state, which greatly improves the overall operational reliability of the equipment.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-7 This invention provides a technical solution: an automatically compensated floating filter, comprising a base 1 and a grinding cylinder 2. The grinding cylinder 2 is fixed on the base 1, and a feed inlet is provided at the lower end of the grinding cylinder 2. A fixing box 4 is fixed at the upper end of the grinding cylinder 2, and an end cap 5 is fixed at the upper end of the fixing box 4. A drain pipe is provided on the side of the fixing box 4. A rotating shaft 6 driven by a motor is provided inside the grinding cylinder 2. An stirring blade 7 is fixed on the rotating shaft 6. A filtering mechanism 8 is fixed on the grinding cylinder 2. An automatically compensated sealing assembly 9 is provided between the filtering mechanism 8 and the rotating shaft 6. An adjusting assembly 10 is also installed on the rotating shaft 6 to realize the initial adjustment function of the sealing assembly 9. A self-locking assembly 11 is also installed on the sealing assembly 9. The self-locking assembly 11 can realize the automatic locking function of the sealing assembly 9 under the action of rotation and centrifugation.

[0019] The filtration mechanism 8 includes a filter cylinder 801 nested within the grinding cylinder 2. Lower filter holes 802 are evenly distributed on the lower end face of the filter cylinder 801. An end plate 803 is mounted on the upper end of the filter cylinder 801, and upper filter holes 804 are evenly distributed on the end plate 803. The filter cylinder 801 and the end plate 803 are locked to the grinding cylinder 2 by bolts. Sealing components 9 are provided between the filter cylinder 801, the end plate 803, and the rotating shaft 6. The sealing components 9 include components that are fixed to the rotating shaft 6. The positioning ring 901 has an elastic sealing ring 902 nested inside it. A locking block 903 is evenly fixed to the sealing ring 902 at equal angles, and the locking block 903 is engaged with the positioning ring 901. Two sets of first inclined ring plates 904 are also fixed inside the sealing ring 902, and the first inclined ring plate 904 and the second inclined ring plate 905 are slidably connected. A bracket 906 is fixed inside the second inclined ring plate 905. The bracket 906 is slidably connected to the positioning ring 901 and the rotating shaft 6; a vertical rod 907 is fixed to the lower end of the bracket 906, and the vertical rod 907 is slidably connected to the fixing plate 908, which is fixed inside the rotating shaft 6. A first spring 909 is also fixed between the vertical rod 907 and the fixing plate 908, providing a preload force to the vertical rod 907; the adjusting assembly 10 includes a movable ring 10 slidably connected to the rotating shaft 6. 01, and a slide rod 1002 is fixed inside the movable ring 1001, and the slide rod 1002 is slidably connected to the rotating shaft 6; one end of the slide rod 1002 is fixed to one end of the round rod 1003, and the round rod 1003 is slidably connected to the vertical rod 907, and a second spring 1004 is fixed between the other end of the round rod 1003 and the rotating shaft 6. At the same time, a pressure plate 1005 is also fixed on the round rod 1003, and the pressure plate 1005 and the bracket 906 are distributed in a one-to-one correspondence. When using this automatically compensated floating filter, such as Figures 1-7As shown, when installing the sealing ring 902, pressing down the movable ring 1001 causes the sliding rod 1002 to move downwards, which in turn drives the round rod 1003 to move downwards. At this time, the second spring 1004 contracts under force. As the round rod 1003 moves downwards, it simultaneously drives the pressure plate 1005 to move downwards. When the pressure plate 1005 contacts the bracket 906, the bracket 906 moves downwards under the action of the pressure plate 1005. Combined with the sliding guide action between the vertical rod 907 and the fixed plate 908, the movement of the bracket 906 can be guaranteed. To ensure stability, the first spring 909 contracts to achieve initial pre-tightening, and the second inclined ring plate 905 is at its lowest position. The sealing ring 902 deforms due to its own elasticity and nests with the positioning ring 901. Combined with the locking action between the locking block 903 and the positioning ring 901, the sealing ring 902 and positioning ring 901 are positioned, ensuring the stability of the sealing ring 902 installation. This completes the installation of the sealing ring 902. Then, the filter cartridge 801 and the grinding cartridge 2 are nested together. The filter cylinder 801, end plate 803, and grinding cylinder 2 are locked together with bolts. At this time, the filter cylinder 801 and end plate 803 are in contact with the corresponding sealing rings 902. The fixing box 4 and end cover 5 are also locked together with the grinding cylinder 2 with bolts, so that the end cover 5 is in contact with the uppermost sealing ring 902. By releasing the movable ring 1001, the slide rod 1002, round rod 1003, and pressure plate 1005 are reset under the elastic action of the second spring 1004. When the pressure plate 1005 separates from the bracket 906... At this time, under the elastic action of the first spring 909, the bracket 906 and the second inclined ring plate 905 can be moved upward and reset. When the second inclined ring plate 905 contacts the first inclined ring plate 904, the elastic force of the first spring 909 can make the second inclined ring plate 905 and the first inclined ring plate 904 in close contact, so that the sealing ring 902 at the corresponding position is in close contact with the filter cylinder 801, the end plate 803, and the end cover 5, ensuring the sealing performance. At this time, the first spring 909 is still in the contracted and pre-tightened state. During subsequent use of the device, the rotating shaft 6 is driven by a motor to rotate, which in turn drives the stirring blades 7 to stir the material and grinding media balls, thereby achieving material grinding. When the rotating shaft 6 rotates, it simultaneously drives the support 906, positioning ring 901, second inclined ring plate 905 and sealing ring 902 to rotate. During long-term use, the sealing ring 902 inevitably comes into contact with the filter cylinder 801, end plate 803 and end cover 5, causing wear. When the sealing ring 902 wears and a gap exists, the support 906 and second inclined ring plate 905 can move upward a certain distance under the elastic action of the first spring 909. Combined with the sliding action between the second inclined ring plate 905 and the first inclined ring plate 904, the sealing ring 902 can be evenly stressed and expand outward, thereby achieving automatic gap compensation, ensuring the sealing performance of the device, and better meeting the actual use requirements. The self-locking assembly 11 includes a mounting plate 1101 fixed to the lower end of the vertical rod 907, and a support plate 1102 fixed to the lower end surface of the mounting plate 1101. A horizontal rod 1103 is slidably connected to the support plate 1102. A counterweight 1104 is fixed to one end of the horizontal rod 1103, and a third spring 1105 is fixed between the counterweight 1104 and the support plate 1102. A locking tooth block 1106 is fixed to the other end of the horizontal rod 1103. The locking tooth block 1106 and the locking tooth ring plate 1107 cooperate to form a locking mechanism. The locking tooth ring plate 1107 is fixed inside the rotating shaft 6, and the locking tooth ring plate 1107 and the rotating shaft 6 are distributed in a one-to-one correspondence. During the use of the device, such as Figures 1-7 As shown, when the rotating shaft 6 is not rotating, the toothed block 1106 and the toothed ring plate 1107 are separated. That is, the bracket 906 and the second inclined ring plate 905 are in a flexible support state of the first spring 909. This ensures that the sealing ring 902 can automatically compensate under the action of the first spring 909, so that the sealing ring 902 at the corresponding position can be in close contact with the filter cylinder 801, the end plate 803, and the end cover 5 to achieve a seal. When the rotating shaft 6 rotates, the material is ground. The rotation of the rotating shaft 6 synchronously drives the counterweight block 1104 to rotate. Under the centrifugal force of rotation, the counterweight block 1104 can be moved, cooperating with the crossbar 11 The sliding guide action between 03 and the support plate 1102 can ensure the stability of the movement of the counterweight 1104. At this time, the third spring 1105 is compressed under force. When the crossbar 1103 slides behind, it drives the toothed block 1106 to move synchronously until the toothed block 1106 engages with the toothed ring plate 1107 to achieve locking. This achieves rigid locking of the positions of the vertical rod 907, the support 906, the second inclined ring plate 905, the first inclined ring plate 904 and the sealing ring 902. This ensures that during the operation of the device, the second inclined ring plate 905 is not moved due to vibration or other factors, which would affect the sealing effect of the sealing ring 902 and further ensure the sealing performance of the device. A cooling jacket 3 is provided on the outside of the grinding cylinder 2, and a cooling cavity is formed between the cooling jacket 3 and the grinding cylinder 2. A water inlet is installed at the lower end of the cooling jacket 3, and a water outlet is installed at the upper end of the cooling jacket 3. During the grinding process, the device continuously feeds material and water through the feed inlet at the lower end of the grinding cylinder 2. The ground material is filtered through the lower filter hole 802 and the upper filter hole 804 and enters the fixed box 4. The ground material is discharged through the drain pipe on the side of the fixed box 4 for collection. Large particles and grinding media balls remain in the grinding cylinder 2 to continue grinding, ensuring the processing quality of the material. During the grinding process, an external water pump can send cooling water from the cooling water tank into the cooling jacket 3 through the water inlet on the cooling jacket 3, forming a cooling cavity with the grinding cylinder 2, thereby achieving the cooling effect of the grinding cylinder 2. The cooling water flows back into the cooling water tank through the water outlet on the cooling jacket 3 and the conduit, thereby achieving the circulating cooling effect of the device.
