Description

Technical Field

[0001] This utility model relates to the field of rubber strip technology, specifically to a vibrating screen rubber strip. Background Technology

[0002] Currently, in oil drilling operations, solid phase (drill cuttings) separation of drilling fluid plays a crucial role in improving drilling speed, reducing wear on drilling rig circulation systems, and lowering drilling costs. Currently, primary solid phase separation of drilling fluid is achieved using vibrating screens. However, the screen mesh of these vibrating screens is fixed to the screen box slats by pull plates. Large gaps easily appear between the screen mesh and the screen box slats, allowing oil sludge to fall below the screen through these gaps, thus affecting the screening effect.

[0003] Patent document CN222901789U discloses a sealing strip for a vibrating screen mesh, including a support strip fixed to the inner wall of the screen box. A connecting strip with an inverted L-shaped cross-section is detachably and fixedly connected to the upper end of the support strip. The connecting strip includes a straight portion and a vertical portion. A sealing strip is installed between the vertical portion of the connecting strip and the side wall of the screen box on one side, sealing the sealing strip with the inner wall of the screen box on one side. A stopper strip is fixed to the upper end of the sealing strip, integrally formed with the sealing strip. The stopper strip includes a vertical portion and an inclined portion at the upper end of the vertical portion, integrally formed. The inclined portion of the stopper strip slopes downwards at the end away from the vertical portion. The vertical portion of the stopper strip seals the inner wall of the screen box on one side. A screen frame is located between the stopper strip and the sealing strip. The vertical portion of the stopper strip is located between the screen frame and the screen box. The screen frame and the screen box are tightly against the vertical portion of the stopper strip, sealing the screen frame with the stopper strip and the sealing strip. A screen mesh is fixed inside the screen frame. In this technical solution, a stopper fixedly connected to the screen box is used to limit the screen frame. When the rubber strip and the stopper need to be replaced, the stopper needs to be disassembled, which makes the replacement of the rubber strip and the stopper troublesome.

[0004] Patent document CN205361926U discloses a sealing structure for a vibrating screen in mud slurry. This sealing structure is installed between the screen support frame and the screen inside the screen box of the vibrating screen. It includes a U-shaped groove and a rectangular cross-section rubber sealing strip. The bottom of the U-shaped groove has a connection hole along its length for fixed connection with the screen support frame. The rectangular cross-section sealing strip is embedded in the U-shaped groove and extends beyond its upper surface. In this patent's technical solution, the screen contacts the screen box, and the sealing contact between the screen and the screen support frame is achieved through the rubber sealing strip contacting the lower end of the screen and the upper end of the screen support frame. However, during operation, if the connection between the screen and the screen box becomes loose, the screen can easily slide relative to the screen box, leading to wear on both the screen and the screen box. Utility Model Content

[0005] The main purpose of this invention is to provide a vibrating screen rubber strip with good sealing performance, convenient rubber strip replacement, and the ability to prevent wear on the screen frame and drying box.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A vibrating screen rubber strip includes an installation groove, in which a rubber strip is inserted. One end of the rubber strip protrudes to the outside of the installation groove. A baffle is provided on one side of the rubber strip, located outside the installation groove. The baffle is made of rubber. The baffle and the rubber strip partially surround the installation end of the screen frame. Multiple mounting bolts are threaded onto the installation groove and are arranged linearly along the length of the installation groove. The rubber strip has elongated holes corresponding to the mounting bolts, through which the mounting bolts pass. A pad is fixed to one end of the rubber strip in the installation groove. A slot is provided at the bottom of the installation groove, in which an insert plate is inserted. The insert plate abuts against the pad plate, and the insert plate is detachably and fixedly connected to the installation groove.

[0008] Specifically, it also includes an upper plate and a lower plate set at the top and bottom. Both the upper plate and the lower plate are fixedly connected to the screen box. The opposite end faces of the upper plate and the lower plate are fixed with mounting grooves. The mounting grooves on the upper and lower sides are symmetrically arranged. The screen frame is located between the upper and lower rubber strips. The screen mesh is fixed inside the screen frame. The baffle is in sealed contact with the screen box and the screen frame.

[0009] Specifically, a mounting plate is fixed to one end of the insert plate, and the mounting plate and the insert plate are connected by screws.

[0010] Specifically, the upper plate is inserted into the groove on the screen box, and the upper plate is connected to the screen box by multiple positioning bolts. A baffle is fixed at the upper end of the upper plate, and the baffle contacts the inner wall of the screen box.

[0011] Specifically, the rubber strip has an inner hole, and the axial direction of the inner hole is parallel to the length direction of the rubber strip.

[0012] Specifically, the baffle strip and the rubber strip are integrally formed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The rubber strip is positioned by inserting a slot into the plate and securing it with screws. Disassembly is simple: just remove the plate and mounting bolts to pull out the rubber strip and stop bar, making replacement easy.

[0015] 2. The rubber strip has elongated holes that mate with the mounting bolts, allowing for fine-tuning of its position during installation. This design ensures reliable fixation while compensating for dimensional errors caused by thermal expansion and contraction or vibration deformation of the screen frame, significantly reducing the risk of shearing damage to the rubber strip.

[0016] 3. The symmetrically arranged rubber strips and baffles form a three-dimensional surrounding structure. The baffles seal against the inner wall of the screen box, and the rubber strips clamp the screen frame, improving the sealing effect between the screen frame and the screen box. The baffles and rubber strips are integrally molded, eliminating the stress concentration problem at the traditional adhesive interface.

[0017] 4. The upper plate adopts a composite fixing method of groove insertion and positioning bolts, which not only ensures installation rigidity, but also enables quick replacement of screen frames.

[0018] 5. The inner hole allows the rubber strip to expand and adjust the sealing contact surface when the screen frame expands due to thermal expansion or installation errors, preventing local stress from exceeding the limit. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Refer to Figures 1-2 As shown, a vibrating screen rubber strip includes a mounting groove 6, into which a rubber strip 12 is inserted. One end of the rubber strip 12 protrudes to the outside of the mounting groove 6. A baffle 13 is provided on one side of the rubber strip 12, located outside the mounting groove 6. The baffle 13 is made of rubber and is integrally formed with the rubber strip 12. The baffle 13 and the rubber strip 12 partially surround the mounting end of the screen frame 14.

[0024] The rubber strip 12 has an inner hole 16, the axial direction of which is parallel to the length direction of the rubber strip 12. The inner hole 16 allows the rubber strip 12 to adjust the sealing contact surface by expanding when the screen frame 14 expands due to thermal expansion or installation errors, thus preventing local stress from exceeding the limit.

[0025] Multiple mounting bolts 11 are threaded onto the mounting groove 6. The mounting bolts 11 are arranged linearly along the length of the mounting groove 6. The rubber strip 12 has elongated holes 10 corresponding to the mounting bolts 11. The mounting bolts 11 pass through the elongated holes 10. One end of the rubber strip 12 in the mounting groove 6 is fixed with a pad 9. The bottom of the mounting groove 6 has a slot 17. A plate 7 is inserted into the slot 17 and presses against the pad 9.

[0026] The insert plate 7 is detachably and fixedly connected to the mounting slot 6. Specifically, a mounting plate 8 is fixed to one end of the insert plate 7, and the mounting plate 8 is connected to the insert plate 7 by screws.

[0027] It also includes an upper plate 3 and a lower plate 2 set at the top and bottom. The upper plate 3 and the lower plate 2 are both fixedly connected to the screen box 1.

The screen frame 14 is located between the upper and lower rubber strips 12. The screen mesh 15 is fixed inside the screen frame 14. The baffle 13 is in sealed contact with the screen box 1 and the baffle 13 is in sealed contact with the screen frame 14.

[0028] The rubber strips 12 and baffles 13 on the upper and lower sides can make sealed contact with the screen frame 14. After the screen frame 14 is installed, the sealing performance is good. When the screen box 1 drives the screen frame 14 to move, it can prevent drilling fluid from being discharged from the gap between the screen frame 14 and the screen box 1.

[0029] When replacing the rubber strip 12 and the baffle 13, remove the screws and mounting bolts 11, and pull the insert plate 7 out of the slot 17. At this time, the rubber strip 12 and the baffle 13 can move away from the screen frame 14, making it easy to pull out the baffle 13 and the rubber strip 12 for replacement.

[0030] After installing the new rubber strip 12 in the mounting groove 6, connect the mounting bolt 11 to the mounting groove 6 and pass through the elongated hole 10 of the rubber strip 12. After inserting the insert plate 7 into the slot 17, the insert plate 7 can press tightly against the pad 9, thereby making the rubber strip 12 press tightly against the screen frame 14. After the insert plate 7 is inserted into the slot 17, connect the mounting plate 8 to the mounting groove 6 using screws.

[0031] Example 2: Based on Example 1, referring to... Figure 1 As shown, the lower plate 2 is fixedly connected to the screen box 1, and the upper plate 3 is inserted into the groove on the screen box 1.

[0032] The upper plate 3 is detachably and fixedly connected to the screen box 1. When the screen frame 14 and screen 15 need to be replaced, the upper plate 3, the upper mounting groove 6, the upper rubber strip 12, and the upper baffle 13 can be disassembled to replace the screen frame 14 and screen 15. This embodiment facilitates the replacement of the screen frame 14 and screen 15.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
