Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration technology, and more specifically, to a vacuum belt filter. Background Technology
[0002] Vacuum belt filters are commonly used solid-liquid separation equipment in various fields such as chemical, pharmaceutical, food, and environmental protection. Their working principle utilizes vacuum to create negative pressure on the filter surface, causing the liquid in the material to be drawn away through the filter surface, while solid particles remain on the filter surface to form a filter cake, thus achieving solid-liquid separation. Vacuum belt filters include discharge rollers and tension springs. During the filtration process, the discharge rollers unload the material from the filter surface, while the tension springs maintain the tension of the filter surface to ensure smooth unloading. However, existing vacuum belt filter unloading devices can only scrape off a fixed thickness of material, with limited adjustment capabilities. In use, the difficulty in automatically adjusting according to the thickness of the conveyed material may lead to poor scraping performance. Utility Model Content

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0024] It should be noted that, in the embodiments of this utility model, the width direction and the conveying direction are as follows: Figure 1 As shown, the width direction and the conveying direction are set at an angle.
[0025] like Figures 1 to 4 As shown, an embodiment of this utility model provides a vacuum belt filter. The vacuum belt filter includes a support part 2; a conveying part 20, which has a filter surface 16 for filtering materials, and along the conveying direction of the conveying part 20, the conveying part 20 also has a first end and a second end disposed opposite to each other, the first end and the second end being disposed on the support part 2; a scraping part, including a counterweight member 40 and a scraping member 30 connected to the counterweight member 40, the scraping member 30 being rotatably disposed on the support part 2, the scraping member 30 having a scraping end, the counterweight member 40 being floatably disposed relative to the support part 2, the counterweight member 40 being used to provide an abutment force to the scraping member 30 to drive the scraping end to abut against the filter surface 16; and a first collecting part 12, located below the scraping end.
[0026] In the above technical solution, the material moves along the conveying direction of the conveying section 20 to the scraping member 30. When the material thickness on the filter surface 16 is thin, under the action of the counterweight member 40, the scraping end is in close contact with the filter surface 16, so that the scraping end can scrape off the material, and the scraped material falls into the first collection section 12. When the material thickness on the filter surface 16 is thick, the scraping end will drive the scraping member 30 to rotate and drive the counterweight member 40 to move. Under the action of the counterweight member 40, the scraping end and the filter surface 16 are still in contact, so that the scraping end scrapes off the thicker material. Compared with the prior art where the scraping end can only scrape off material of a fixed thickness, in this embodiment, by setting the counterweight member 40 and rotatably setting the scraping member 30 on the support section 2, the scraping end can scrape off material of different thicknesses. In this way, the adjustment capability of the vacuum belt filter can be improved, thereby improving the scraping effect of the vacuum belt filter.
[0027] Specifically, in the embodiments of this utility model, the material conveyed by the conveying unit 20 is lithium carbonate. Under the action of the filter surface 16, the solid lithium carbonate in the material remains on the filter surface 16 and is scraped off into the first collection unit 12 by the scraping member 30.
[0028] Specifically, in the embodiments of this utility model, the scraping component 30 is rotatably mounted on the support part 2. The rotatable scraping component 30 can adjust its angle according to the thickness of the material. In this way, the scraping end can adapt to materials of different thicknesses on the filter surface 16, enhance the scraping effect on the material, and reduce damage to the filter surface 16.
[0029] Specifically, in the embodiments of this utility model, the first collecting part 12 is a storage box.
[0030] like Figures 1 to 4 As shown in the embodiment of this utility model, the counterweight component 40 includes a first elastic element 7 and a counterweight 6. The counterweight 6 is connected to the scraping component 30. One end of the first elastic element 7 abuts against the support part 2, and the other end of the first elastic element 7 abuts against the counterweight 6.
[0031] In the above technical solution, when the material at the scraping end changes from thin to thick, the scraping component 30 rotates, the counterweight 6 moves away from the support part 2, and the first elastic element 7 extends and lifts the counterweight 6; when the material at the scraping end changes from thick to thin, the scraping component 30 rotates, the counterweight 6 moves closer to the support part 2, and the first elastic element 7 can play a buffering role to avoid the counterweight 6 directly impacting the support part 2.
[0032] Specifically, in the embodiments of this utility model, the first elastic element 7 is a spring.
[0033] Specifically, in the embodiments of this utility model, the scraping end can be made to contact the filter surface 16 under the gravity of the counterweight 6.
[0034] like Figures 1 to 4 As shown in the embodiment of this utility model, the counterweight component 40 further includes a first telescopic component 13, and a first elastic component 7 is sleeved on the outer periphery of the first telescopic component 13. The first telescopic component 13 includes a first sleeve and a first guide post. The first sleeve and the first guide post are slidably engaged. The first sleeve is connected to the support part 2, and the first guide post is connected to the counterweight component 6.
[0035] In the above technical solution, the first guide post can guide the first elastic member 7 so that the first elastic member 7 moves along the axial direction of the first telescopic member 13, thereby avoiding the phenomenon of the first elastic member 7 deviating when moving.
[0036] Specifically, in the embodiments of this utility model, when the thickness of the material on the filter surface 16 changes (when the material changes from thin to thick), the scraping member 30 rotates, and the counterweight 6 drives the first guide column to move away from the support part 2, so that the first elastic member 7 extends; when the material on the filter surface 16 changes from thick to thin, the counterweight 6 can move towards the support part 2, so that the first guide column moves towards the support part 2, and the first elastic member 7 provides a buffering force, so that the scraping member 30 rotates, so that the filter surface 16 and the scraping end fit tightly together.
[0037] Specifically, in the embodiments of this utility model, the counterweight 6 is a counterweight block.
[0038] like Figures 1 to 4 As shown in the embodiment of the present invention, the scraping component 30 includes a first plate segment 31, a second plate segment 32 and a third plate segment 33 connected in sequence and arranged at an angle. The scraping end is formed on the side of the second plate segment 32 facing the filter surface 16. The first plate segment 31 and the third plate segment 33 are rotatably connected to the support part 2 respectively. At least one of the first plate segment 31 and the third plate segment 33 is provided with a counterweight component 40.
[0039] In the above technical solution, on the one hand, the first plate segment 31 and the third plate segment 33 are rotatably connected to the support part 2, so that the scraping end can automatically adjust the angle according to the thickness and hardness of the material, ensuring the best contact state between the scraping end and the filter surface 16 during the scraping process, thereby improving the scraping effect; on the other hand, compared with the first plate segment 31 or the third plate segment 33 being rotatably connected to the support part 2 on one side, the first plate segment 31 and the third plate segment 33 being rotatably connected to the support part 2 respectively can make the scraping component 30 more stable during operation, thereby improving the stability of scraping.
[0040] Specifically, in the embodiments of this utility model, the included angle between the first plate segment 31 and the second plate segment 32 is 90°, and the included angle between the second plate segment 32 and the third plate segment 33 is 90°.
[0041] like Figures 1 to 4 As shown in the embodiment of this utility model, there are two counterweight components 40. One of the two counterweight components 40 is connected to the first plate segment 31, and the other counterweight component 40 is connected to the third plate segment 33.
[0042] In the above technical solution, the two independent counterweight components 40 can control the movement of the first plate segment 31 and the third plate segment 33 respectively, ensuring that the material can be kept balanced in the width direction of the conveying section 20 during the scraping process. In this way, the problem of poor scraping effect caused by uneven force on one side can be avoided, and the stability of the vacuum belt filter is improved.
[0043] Specifically, in the embodiments of this utility model, two counterweight components 40 are respectively connected to both ends of the scraping component 30, which not only enhances the scraping effect but also simplifies the maintenance process. When it is necessary to replace the counterweight component 40, each counterweight component 40 can be operated independently, reducing the workload of maintenance and improving the efficiency of maintenance.
[0044] like Figures 1 to 4 As shown in the embodiment of this utility model, the vacuum belt filter also includes two pivot members 3, which are connected to the first plate segment 31 and the third plate segment 33 respectively. Along the width direction of the conveying part 20, the two sides of the support part 2 are respectively provided with through holes. The two pivot members 3 are rotatably engaged with the two through holes respectively, and the width direction and the conveying direction are set at an angle.
[0045] In the above technical solution, the setting of two pivots 3 can realize the rotation of the scraping component 30, so that the scraping end can automatically adjust the angle of contact with the filter surface 16 according to the thickness of the material. This dynamic adjustment capability ensures the safety of the scraping process and prevents material residue or excessive wear of the filter surface 16 by the scraping component 30 due to improper scraping angle.
[0046] Specifically, in the embodiments of this utility model, the pivot member 3 is a rotating shaft.
[0047] Specifically, in the embodiments of this utility model, the pivot axis of the pivot member 3 is located between the counterweight member 6 and the second plate segment 32.
[0048] like Figure 4 As shown in the embodiment of this utility model, the second plate segment 32 is made of ribbed steel.
[0049] With the above settings, compared to metal scrapers or hard plastic scrapers, the rubber scraper has a certain degree of elasticity. The rubber scraper can make gentler contact with the filter surface 16, reducing scratches or damage to the filter surface 16. In this way, the service life of the vacuum belt filter can be extended.
[0050] In existing technology, during the operation of a vacuum belt filter, there may be material that has not been completely scraped off on the filter surface 16. This residual material on the filter surface 16 may fall to the bottom of the conveying section during transport, resulting in material waste. Therefore, if... Figures 1 to 3 As shown in the embodiment of this utility model, the vacuum belt filter also includes a frame 1, a first collecting part 12 and a supporting part 2 are disposed on the frame 1, the frame 1 is provided with a first receiving groove and a first opening communicating with the first receiving groove, the first opening is disposed facing the conveying part 20; a second collecting part 8 is disposed inside the first receiving groove, the second collecting part 8 is disposed corresponding to the first opening, and the second collecting part 8 is used to collect the material falling from the filter surface 16.
[0051] In the above technical solution, the frame 1 is provided with a first receiving groove and a first opening communicating with the first receiving groove, and the first opening faces the conveying part 20. This layout allows the material that cannot be completely scraped off on the filter surface 16 to fall naturally into the second collection part 8, which improves the efficiency of material collection and avoids the problem of material waste.
[0052] Specifically, in the embodiments of this utility model, the second collection part 8 is a storage box. The second collection part 8 is set inside the frame 1, which makes full use of the internal space of the frame 1 and reduces the floor space occupied by the vacuum belt filter.
[0053] Specifically, in an embodiment of this utility model, the frame 1 is provided with a second receiving groove, and the first collecting part 12 is placed in the second receiving groove.
[0054] Specifically, in the embodiments of this utility model, the second collecting part 8 has a third receiving groove and a second opening communicating with the third receiving groove, and the first opening and the second opening are correspondingly arranged.
[0055] like Figure 1 and Figure 2 As shown in the embodiment of this utility model, along the conveying direction, the second collecting part 8 is provided with sliding members 9 on both sides, and the inner wall surface of the receiving groove is provided with sliding grooves 10 on both sides, and the two sliding grooves 10 are respectively slidably engaged with the two sliding members 9.
[0056] In the above technical solution, by setting the sliding groove 10 and the sliding member 9, when the second collecting part 8 needs to be installed, the second collecting part 8 can be pushed into the receiving groove by the two sliding members 9 respectively sliding with the two sliding grooves 10 to collect the dropped material; when the second collecting part 8 needs to be cleaned, the second collecting part 8 can be pulled out.
[0057] Specifically, in the embodiments of this utility model, the conveying unit 20 can be arranged horizontally relative to the frame 1, or the conveying unit 20 can be arranged at an angle relative to the frame 1.
[0058] like Figure 2 and Figure 5 As shown in the embodiment of this utility model, along the conveying direction, a limiting member 50 is provided on one side of the second collecting part 8, and a limiting groove is provided on the inner wall of the receiving groove. The limiting member 50 includes a second elastic member 21; a limiting member 11, which is configured to cooperate with the limiting groove; a second telescopic member 19, which includes a second guide post and a second sleeve, the second sleeve being connected to the limiting member 11, the second guide post being connected to the sliding member 9, the second guide post and the second sleeve being slidably engaged; the second elastic member 21 being sleeved on the outer periphery of the second telescopic member 19, and the two ends of the second elastic member 21 abutting against the limiting member 11 and the sliding member 9 respectively; and a handle 51, which is connected to the second sleeve and extends along the width direction and out of the receiving groove.
[0059] In the above technical solution, when the second collecting part 8 needs to be installed, the handle 51 is pushed along the width direction to move the second sleeve towards the sliding member 9, compressing the second elastic member 21. After the second collecting part 8 and the limiting member 11 begin to enter the second receiving groove, the handle 51 is released. Due to its elastic restoring force, the second elastic member 21 drives the second sleeve to move away from the sliding member 9. Then, the second collecting part 8 is continued to be pushed so that the sliding member 9 slides on the sliding groove 10 until the limiting member 11 is engaged with the limiting groove, thus realizing the second collecting part 8 in the second receiving groove. The position is locked in the width direction to ensure that the second collection section 8 will not move due to the impact of materials or the vibration of the vacuum belt filter during the filtration process. When the second collection section 8 needs to be cleaned, push the handle 51 again in the width direction to compress the second elastic member 21, so that the limiting member 11 is disengaged from the limiting groove. Due to the separation of the limiting member from the limiting groove, the second collection section 8 is no longer restricted by the positioning in the conveying direction. The second collection section 8 can be easily pulled out of the receiving groove in the width direction to facilitate the unloading of materials and the cleaning of the second collection section 8.
[0060] Specifically, in the embodiments of this utility model, the second telescopic member 19 can guide the second elastic member 21 so that the second elastic member 21 moves along the axial direction of the second telescopic member 19, thereby avoiding the phenomenon of the second elastic member 21 deviating when moving.
[0061] Specifically, in the embodiments of this utility model, the handle 51 includes a connecting rod 511 and a handle 512. One end of the connecting rod 511 is connected to the second sleeve, and the other end of the connecting rod 511 is connected to the handle 512.
[0062] Specifically, in the embodiments of this utility model, the second elastic member 21 is a spring, one end of the second elastic member 21 is connected to the limiting member 11, and the other end of the second elastic member 21 is connected to the sliding member 9.
[0063] Specifically, in the embodiments of this utility model, the limiting member 11 is a ball-locking device.
[0064] Specifically, in the embodiments of this utility model, the end of the second telescopic member 19 connected to the limiting member 11 is provided with a handle 51.
[0065] Specifically, in the embodiments of this utility model, the vacuum belt filter further includes multiple support columns 17 and multiple bases 18. The multiple support columns 17 and multiple bases 18 are connected to each other. One end of the support column 17 is connected to the frame 1, and the other end of the support column 17 is connected to the base 18. The support columns 17 and bases 18 can support the frame 1, thereby improving the stability of the vacuum belt filter.
[0066] Specifically, in the embodiments of this utility model, the conveying unit 20 includes a servo motor 14 and an output shaft connected to the servo motor 14. The conveying unit 20 also includes two pulleys 15, which are respectively disposed at the first end and the second end. The servo motor 14 drives one of the two pulleys 15 to rotate through the output shaft, so that the filter surface 16 moves along the conveying direction, thereby driving the other pulley 15 to rotate.
[0067] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the material moves along the conveying direction of the conveying section to the scraping member, when the material thickness on the filter surface is thin, under the action of the counterweight member, the scraping end is in close contact with the filter surface, so that the scraping end can scrape off the material, and the material scraped off by the scraping end falls into the first collection section; when the material thickness on the filter surface is thick, the scraping end will drive the scraping member to rotate and drive the counterweight member to move, and under the action of the counterweight member, the scraping end and the filter surface are still in contact, so that the scraping end scrapes off the thicker material. Compared with the prior art where the scraping end can only scrape off material of a fixed thickness, in this embodiment, by setting the counterweight member and rotatably setting the scraping member on the support, the scraping end can scrape off material of different thicknesses, thus improving the adjustment capability of the vacuum belt filter and improving the scraping effect of the vacuum belt filter.
[0068] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
