Description

Technical Field

[0001] This utility model relates to the field of composite cylindrical screen technology, specifically a composite cylindrical screen. Background Technology

[0002] The working part of a cylindrical screen is cylindrical, with the entire screen rotating around its axis, which is typically installed at a small angle. Material is fed in from one end of the cylinder; fine particles pass through the screen openings on the cylindrical working surface, while coarse particles are discharged from the other end. Cylindrical screens operate at very low speeds, ensuring stable operation and good dynamic balance.

[0003] Existing cylindrical screens are generally designed as a single piece when they are made into screen cylinders. However, if there is a break in a part of the cylindrical screen, the entire cylindrical screen needs to be replaced, which is wasteful. Therefore, it is necessary to optimize a composite cylindrical screen through technological innovation and design. Utility Model Content

[0004] Existing cylindrical screens are generally designed as a single piece when manufactured into a screen cylinder. However, if a part of the cylindrical screen is damaged, the entire screen needs to be replaced, which is wasteful. To solve this problem, this application provides a composite cylindrical screen. By disassembling the screen cylinder into a connectable fixed cylinder and a connecting cylinder, partial replacement can be performed when a part of the screen cylinder is damaged, without replacing the entire screen cylinder, thus reducing resource waste. When the spring is compressed, it drives the limiting post to insert into the limiting hole on the insert plate through the baffle, thereby enabling quick assembly and disassembly of the connecting cylinder and the fixed cylinder, accelerating the replacement efficiency. A guide mechanism is set to guide the connection of the fixed cylinder and the connecting cylinder, eliminating the need for workers to lift the connecting cylinder for positioning, which is more convenient.

[0006] A composite cylindrical screen, comprising:

[0007] Two fixed cylinders;

[0008] A connecting cylinder, located between the two fixed cylinders;

[0009] A connecting mechanism, located between the connecting cylinder and the fixed cylinder, is used to connect the fixed cylinder and the connecting cylinder;

[0010] A guiding mechanism is located between the fixed cylinder and the connecting cylinder, and is used to guide the fixed cylinder and the connecting cylinder.

[0011] In one possible implementation, the fixing cylinder includes a fixing ring, a second ring is provided on the side of the fixing ring near the connecting cylinder, a connecting rod is fixed between the fixing ring and the second ring, and a second mesh cylinder is fixed between the fixing ring and the second ring.

[0012] In one possible implementation, the connecting cylinder includes two rings, which are fixed together by a connecting rod, and a mesh cylinder is fixed between the two rings.

[0013] In one possible implementation, the guiding mechanism includes a fixing block four fixed on a ring two, a slot two opened on the side of the fixing block four facing the ring one, a fixing block three fixed on the ring one, and an insert plate two fixed on the side of the fixing block three facing the fixing block four. The insert plate two can be inserted into the slot two. During installation, the insert plate two on the fixing block three can be inserted into the slot two on the fixing block four to guide the connecting cylinder and the fixing cylinder.

[0014] In one possible implementation, the connecting mechanism includes a fixing block two fixed on a ring two, a fixing block one fixed on a ring one, a U-shaped plate one fixed on the fixing block two, a limiting post penetrating the U-shaped plate one, a baffle fixed on the limiting post between the U-shaped plate one and the fixing block two, a spring sleeved on the outside of the limiting post between the baffle and the U-shaped plate one, an insert plate one fixed on the side of the fixing block one facing the fixing block two, a limiting hole formed on the insert plate one, and a slot one formed on the side of the fixing block two facing the fixing block one, the insert plate one can be inserted into the slot one, the spring is in a compressed state, under the action of the spring, the spring will drive the limiting post to be inserted into the limiting hole on the insert plate one through the baffle, thereby fixing the connecting cylinder and the fixing cylinder.

[0015] In one possible implementation, the limiting post passes through the second fixing block, the limiting post can be inserted into the limiting hole, and the limiting post can slide on the second fixing block and the first U-shaped plate, so that the limiting post can move under the action of the spring.

[0016] In one possible implementation, a U-shaped plate is fixed to the second fixing block, the limiting post passes through the U-shaped plate, and a rectangular plate is fixed to the limiting post. The limiting post can slide on the U-shaped plate, making it easy to pull the limiting post through the rectangular plate. At the same time, the U-shaped plate can support the rectangular plate. When the rectangular plate and the slot on the U-shaped plate are perpendicular, the limiting post will not be inserted into the limiting hole, eliminating the need for the worker to hold the limiting post continuously and reducing the worker's workload.

[0017] In one possible implementation, the fixing ring has a fixing hole, and the fixing ring can be fixedly connected to the screening machine by bolts, which facilitates the installation of the fixing cylinder.

[0018] In summary, this utility model has at least one of the following beneficial technical effects:

[0019] 1. By disassembling the screen cylinder into a modular fixed cylinder and a connecting cylinder, partial replacement can be performed when a part of the screen cylinder is damaged, without having to replace the entire screen cylinder, thus reducing the waste of resources.

[0020] 2. When the spring is in a compressed state, it will drive the limiting post to insert into the limiting hole on the insert plate through the baffle, thereby enabling quick disassembly and assembly of the connecting cylinder and the fixed cylinder, thus speeding up the replacement efficiency.

[0021] 3. By setting a guiding mechanism, the connection between the fixed cylinder and the connecting cylinder can be guided, eliminating the need for staff to lift the connecting cylinder for positioning, which is more convenient. Attached Figure Description

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] This embodiment describes the specific structure of a composite cylindrical screen, as detailed in the following reference. Figures 1-4 As shown, a composite cylindrical screen includes:

[0029] Two fixed cylinders;

[0030] A connecting cylinder, located between two fixed cylinders;

[0031] A connecting mechanism is located between the connecting cylinder and the fixed cylinder, and is used to connect the fixed cylinder and the connecting cylinder;

[0032] The guiding mechanism is located between the fixed cylinder and the connecting cylinder and is used to guide the fixed cylinder and the connecting cylinder.

[0033] If a screen cylinder on the market is damaged in one part, the entire cylinder needs to be replaced, which is quite wasteful.

[0034] The fixed cylinder includes a fixed ring 1, a second ring 9 is provided on the side of the fixed ring 1 near the connecting cylinder, a connecting rod 10 is fixed between the fixed ring 1 and the second ring 9, a second mesh cylinder 2 is fixed between the fixed ring 1 and the second ring 9, the connecting cylinder includes two first rings 8, the two first rings 8 are fixed together by the connecting rod 10, and a first mesh cylinder 3 is fixed between the two first rings 8.

[0035] When connecting the fixed cylinder and the connecting cylinder, the guiding mechanism includes a fixing block 6 fixed on the second ring 9. The fixing block 6 has a slot 11 on the side facing the first ring 8. A fixing block 7 is fixed on the first ring 8. An insert plate 20 is fixed on the side of the fixing block 7 facing the fixing block 6. The insert plate 20 can be inserted into the slot 11. During installation, the insert plate 20 on the fixing block 7 can be inserted into the slot 11 on the fixing block 6 to guide the connecting cylinder and the fixed cylinder.

[0036] Generally, bolts are used to fix the two together, but tightening bolts is cumbersome and bolts are easy to lose. The connecting mechanism includes a fixing block 25 fixed on ring 29, a fixing block 14 fixed on ring 18, a U-shaped plate 15 fixed on fixing block 25, a limit post 12 passing through the U-shaped plate 15, a baffle fixed on the limit post 12 between the U-shaped plate 15 and the fixing block 25, and a spring 13 sleeved on the outside of the limit post 12 between the baffle and the U-shaped plate 15. An insert plate 18 is fixed on the side of fixing block 14 facing fixing block 25, and the insert plate 18 has a... The limiting hole 19 and the fixing block 2 5 have a slot 14 on the side facing the fixing block 1 4. The insert plate 18 can be inserted into the slot 14. The spring 13 is in a compressed state. Under the action of the spring 13, the spring 13 will drive the limiting post 12 to be inserted into the limiting hole 19 on the insert plate 18 through the baffle, so as to fix the connecting cylinder and the fixing cylinder. The limiting post 12 passes through the fixing block 2 5 and can be inserted into the limiting hole 19. The limiting post 12 can slide on the fixing block 2 5 and the U-shaped plate 15, so that the limiting post 12 can move under the action of the spring 13.

[0037] Meanwhile, a U-shaped plate 16 is fixed on the fixing block 2 5, and a limiting post 12 passes through the U-shaped plate 2 16. A rectangular plate 17 is fixed on the limiting post 12. The limiting post 12 can slide on the U-shaped plate 2 16, which makes it easy to pull the limiting post 12 through the rectangular plate 17. At the same time, the U-shaped plate 2 16 can support the rectangular plate 17. When the rectangular plate 17 and the slot on the U-shaped plate 2 16 are perpendicular, the limiting post 12 will not be inserted into the limiting hole 19. The staff does not need to hold the limiting post 12 all the time, which reduces the workload of the staff.

[0038] In addition, the fixing ring 1 has a fixing hole, and the fixing ring 1 can be fixedly connected to the screening machine by bolts, which facilitates the installation of the fixing cylinder.

[0039] Among them, both the first type (3) and the second type (2) are composite cylindrical screens.

[0040] When the staff needs to replace the damaged screen cylinder, first remove the fixed cylinder along with the connecting cylinder from the screening machine. Then pull the rectangular plate 17, which drives the baffle to compress the spring 13. At the same time, the limiting post 12 moves out of the limiting hole 19. Rotate the rectangular plate 17 until it is perpendicular to the groove on the U-shaped plate 16, so that the U-shaped plate 16 supports the rectangular plate 17 and prevents the limiting post 12 from entering the limiting hole 19. At this time, the fixed cylinder and the connecting cylinder can be separated, and the damaged one can be replaced. Then, reverse the operation to install the screen cylinder. The operation is relatively convenient and there is no need to replace the entire screen cylinder.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
