Description

Technical Field

[0001] This utility model relates to the field of correction devices, specifically to a bilaterally adjustable two-water filter cloth correction device. Background Technology

[0002] In the production of hemihydrate-dihydrate wet-process phosphoric acid, the problem of filter cloth misalignment in the dihydrate filter during the filtration of the dihydrate slurry is very serious. Existing vacuum filter cloth correction devices, such as the utility model patent with application number CN202420751661.7, disclose an automatic correction device for a belt filter. This device includes a support frame, a left bearing assembly and a movable bracket slidably connected to the support frame along the longitudinal direction, a fixed bracket rotatably connected to the movable bracket, and a right bearing assembly mounted on the fixed bracket. A correction roller arranged laterally is fixedly connected at one end to the left bearing assembly and at the other end to the right bearing assembly. Correction airbags are fixedly mounted on both sides of the support frame, front and rear of the left bearing assembly. When the filter belt misaligns laterally, the correction airbags push the left bearing seat to produce longitudinal displacement, causing the correction roller to deflect at a certain angle. Under the frictional force of the correction roller, the misalignment of the filter cloth is quickly corrected.

[0003] However, existing correction devices only have a correction airbag at one end of the correction roller. If the correction airbag malfunctions during production, a lot of time needs to be spent on downtime for repairs, which affects production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a double-sided adjustable two-water filter cloth correction device, which sets correction airbags at both ends of the correction roller to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bilateral adjustable two-water filter cloth correction device includes a laterally extending correction roller. Support components are provided at both ends of the correction roller. Each support component includes a support base. A bracket is slidably mounted on the support base. Both ends of the correction roller are movably mounted on the corresponding bracket. Correction airbags are connected between the front and rear sides of the bracket and the corresponding support base. A limiting mechanism for preventing the bracket from sliding back and forth is also provided between the bracket and the corresponding support base.

[0007] As a preferred technical solution, the limiting mechanism includes a rack fixedly installed on the support base, the rack extending along the sliding direction of the bracket, and a locking block driven to rise and fall by a telescopic component installed on the bracket, the bottom of the locking block having teeth that mesh with the rack.

[0008] As a preferred technical solution, springs are also connected between the front and rear sides of the bracket and the corresponding support base.

[0009] As a preferred technical solution, the two ends of the correction roller are rotatably mounted on bearing seats, and a vertically extending connecting shaft is fixedly mounted on the bearing seats; a first connecting seat is fixedly mounted on one of the brackets, and a second connecting seat is fixedly mounted on the other bracket; the connecting shaft at one end of the correction roller is rotatably mounted on the first connecting seat, and the connecting shaft at the other end of the correction roller is laterally slidably mounted on the second connecting seat.

[0010] As a preferred technical solution, the second connecting seat is provided with a strip-shaped hole extending laterally in the length direction, and the connecting shaft at the corresponding end of the correction roller is slidably installed in the strip-shaped hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This application provides a set of correction airbags at both ends of the correction roller. In use, the angle of the correction roller is adjusted by the correction airbag at one end of the correction roller. When the correction airbag in use malfunctions, it is switched to another set of correction airbags to adjust the angle of the correction roller. At the same time, the damaged correction airbag is repaired, thereby enabling the repair of the damaged correction airbag without stopping the machine and improving production efficiency.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 3 As shown, a double-sided adjustable two-water filter cloth correction device includes a laterally extending correction roller 1. Support components are provided at both ends of the correction roller 1. The support components include a support base 2. A bracket 3 is slidably installed on the support base 2. The two ends of the correction roller 1 are movably installed on the corresponding bracket 3.

[0020] In this embodiment, the support base 2 is provided with a base plate 4, and the front and rear ends of the base plate 4 are respectively integrally formed with upwardly extending vertical plates 5. Two sliding rods 6 arranged side by side are fixedly installed between the two vertical plates 5 by bolts. The sliding rods 6 extend forward and backward. The bracket 3 is provided with a support plate 7, and the front and rear ends of the support plate 7 are respectively integrally formed with upwardly extending side plates 8. Two sliders 9 arranged opposite each other are fixedly installed at the bottom of the support plate 7 by bolts. The sliders 9 are simultaneously slidably installed on the two sliding rods 6, which guides the forward and backward sliding of the bracket 3.

[0021] Corrective airbags 10 are connected to the front and rear sides of the bracket 3 and the corresponding support bases 2, respectively. Specifically, corrective airbags 10 are provided between the front vertical plate 5 and the side plate 8, and between the rear vertical plate 5 and the side plate 8, respectively. The two ends of the corrective airbags 10 are fixedly connected to the corresponding vertical plate 5 and the side plate 8 by screws. A limiting mechanism for preventing the bracket 3 from sliding back and forth is also provided between the bracket 3 and the corresponding support base 2.

[0022] In this embodiment, the limiting mechanism includes a rack 11 fixedly mounted on the top of the base plate 4 by bolts, the rack 11 extending back and forth along the sliding direction of the bracket 3; a mounting plate 12 is fixedly mounted on the bottom of the two sliders 9 by bolts, and a locking block 13 driven to rise and fall by a telescopic component is provided below the mounting plate 12. The telescopic component is an electric push rod 14 fixedly mounted on the top of the mounting plate 12 by bolts, the output end of the electric push rod 14 extends downward and is fixedly connected to the locking block 13 by bolts, and two vertically extending guide posts 15 arranged opposite each other are fixedly mounted on the top of the locking block 13 by bolts. The guide posts 15 are vertically slidably mounted on the mounting plate 12 to improve the stability of the connection between the locking block 13 and the mounting plate 12; the bottom of the locking block 13 is provided with teeth that mesh with the rack 11.

[0023] In use, the electric push rod 14 at one end of the straightening roller 1 extends and drives the corresponding locking block 13 to move downward and engage with the rack 11, thereby restricting the corresponding support 3 from sliding back and forth along the slide bar 6; at the same time, the straightening airbag 10 at the other end of the straightening roller 1 drives the corresponding support 3 to slide back and forth along the slide bar 6, thereby causing the straightening roller 1 to deflect at a certain angle and realize the straightening of the filter cloth.

[0024] In this embodiment, in the initial state, the locking block 13 at the left end of the correction roller 1 is engaged with the rack 11 downwards, so the bracket 3 at the left end of the correction roller 1 cannot slide back and forth along the slide bar 6 and remains in a fixed state; the locking block 13 at the right end of the correction roller 1 is lifted upwards and separated from the rack 11. By inflating and deflating the two correction airbags 10 at the right end of the correction roller 1, the bracket 3 at the right end of the correction roller 1 is driven to slide back and forth along the slide bar 6, thereby adjusting the deflection angle of the correction roller 1. During use, when the right-side correction airbag 10 of the correction roller 1 malfunctions and cannot adjust the angle of the correction roller 1, the electric push rod 14 at the right end of the correction roller 1 extends to move the corresponding locking block 13 downward and engage with the rack 11, thereby fixing the bracket 3 at the right end of the correction roller 1. Then, the electric push rod 14 at the left end of the correction roller 1 retracts to separate the corresponding locking block 13 from the rack 11, thereby releasing the restriction on the bracket 3 at the left end of the correction roller 1. The angle of the correction roller 1 can be adjusted by using the two correction airbags 10 at the left end of the correction roller 1. At the same time, the damaged airbag at the right end of the correction roller 1 can be repaired. By switching between the left and right ends of the correction airbag 10, the damaged correction airbag 10 can be repaired without stopping the machine, thus improving production efficiency.

[0025] Springs 16 are respectively fitted on the slide rod 6 between the front vertical plate 5 and the side plate 8 and on the slide rod 6 between the rear vertical plate 5 and the side plate 8. When the correction airbag 10 at one end of the correction roller 1 malfunctions, the support 3 can be moved to the center position of the slide rod 6 by the springs 16 located on the front and rear sides of the corresponding support 3.

[0026] The two ends of the straightening roller 1 are rotatably mounted on bearing seats 17, and vertically extending connecting shafts 18 are welded to the top and bottom of the bearing seats 17, respectively. A first connecting seat 19 is fixedly mounted on the left support plate 7 by bolts, and a second connecting seat 20 is fixedly mounted on the right support plate 7 by bolts. Both the first connecting seat 19 and the second connecting seat 20 are rectangular frames. The connecting shaft 18 on the left end bearing seat 17 of the straightening roller 1 is rotatably mounted on the first connecting seat 19. The top and bottom walls of the first connecting seat 19 are respectively... A shaft hole matching the connecting shaft 18 is provided, and the connecting shaft 18 is rotatably disposed in the corresponding shaft hole. The connecting shaft 18 on the right end bearing seat 17 of the straightening roller 1 is laterally slidably mounted on the second connecting seat 20. The top and bottom walls of the second connecting seat 20 are respectively provided with strip-shaped holes 21 matching the connecting shaft. The strip-shaped holes 21 vertically penetrate the corresponding side walls of the second connecting seat 20, and extend laterally in the length direction. The connecting shaft 18 on the right end bearing seat 17 of the straightening roller 1 is slidably mounted in the strip-shaped holes 21. The connecting shaft 18 on the right end bearing seat 17 of the straightening roller 1 can rotate in the strip-shaped holes 21 and move left and right along the strip-shaped holes 21, so as to prevent the straightening roller 1 from bending when the bracket 3 moves back and forth.
