Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically to a novel dual-track vibrating screen. Background Technology

[0002] Currently, a large amount of drilling mud is generated during the extraction and drilling of oil and natural gas. Due to the variety of chemical treatment agents used in the drilling process, the waste drilling mud is severely contaminated with harmful substances such as high COD, dark color, high pH, ​​and high levels of heavy metal ions. Waste drilling mud is one of the main sources of pollution in the oil and gas industry. In order to reduce the pollution caused by drilling mud and reduce drilling costs, drilling mud is usually recycled. In the process of recycling drilling mud, it is necessary to separate the solids carried in the drilling mud through a vibrating screen to facilitate the recycling of drilling mud.

[0003] The screen box and base of a vibrating screen are generally connected by springs. In the prior art, such as the patent document with publication number CN211230315U, a new type of dual-track motion drilling fluid vibrating screen is disclosed. This new type of dual-track motion drilling fluid vibrating screen is equipped with springs. The vibration generated by the second fixed block during operation is transmitted to the spring through the second fixed block, the connecting block and the limiting rod. The spring absorbs most of the vibration, so that the movable box can have a higher vibration intensity and a better screening effect.

[0004] Patent document CN212867468U discloses a dual-track slurry vibrating screen. This dual-track slurry vibrating screen includes a base, a support assembly on the base, and a vibrating box on the support assembly. The support assembly includes two first support plates on the base, a first spring on the first support plates, and a first cover on the first spring. The two first support plates are located on opposite sides of the vibrating box, and the first cover is located on the vibrating box. When the first and second vibration motors operate, they drive the vibrating box to move, which in turn drives the vibrating screen plate to move. Simultaneously, the vibrating box drives the first cover to move, which applies force to the first spring, causing the spring to deform and facilitating the vibration of the vibrating screen plate. The designed support assembly, through the first spring, facilitates the vibration of the vibrating screen plate.

[0005] In existing vibrating screens, the spring end connecting the screen box and the base lacks a stabilizing component. During the vibration of the screen box, when it undergoes elastic deformation, the spring end and the support on one side are prone to relative movement, which makes it impossible to effectively ensure that the screen box moves along the set trajectory. Utility Model Content

[0006] The main objective of this invention is to provide a novel dual-track vibrating screen that can effectively stabilize the end of the spring connecting the base and the screen box, thereby ensuring that the screen box can move along a set trajectory.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: A novel dual-track vibrating screen includes a base and a screen box, which are connected by multiple elastic support components. A power component is fixed inside the screen box. The elastic support components include two symmetrically arranged mounting units connected by springs. Each mounting unit includes a mounting plate with studs fixed on it. The studs are vertically arranged. The mounting plate of the upper mounting unit is fixedly connected to the screen box, and the mounting plate of the lower mounting unit is fixedly connected to the base. Both the front and rear sides of the bolt are machined with flat surfaces. The studs are inserted into the ends connected to the springs. Multiple threaded sleeves are threaded onto the studs, and threaded holes are opened on the threaded sleeves to adjust the height of the threaded sleeves on the studs. The bolts are threaded into the threaded holes, with one end of the bolt tightly abutting against the flat surface on one side. The lower bolt abuts against the spring portion below it and stabilizes the lower end of the spring, while the upper bolt abuts against the spring portion above it and stabilizes the upper end of the spring.

[0008] Specifically, the threaded holes of the two adjacent threaded sleeves are staggered in the front-to-back direction.

[0009] Specifically, the outer edge of the threaded sleeve contacts the inner side of the spring.

[0010] Specifically, the number of elastic support components is at least four, with two elastic support components on both the front and rear sides of the screen box. The two elastic support components on the front side of the screen box are arranged symmetrically from left to right, and the two elastic support components on the rear side of the screen box are arranged symmetrically from left to right.

[0011] Specifically, the power assembly includes a mounting frame fixed inside the screen box, with two first vibration motors fixed on the left side of the mounting frame and a second vibration motor fixed on the right side of the mounting frame.

[0012] Specifically, the mounting frame includes a mounting tube arranged longitudinally, with flanges fixed at both ends of the mounting tube. The flanges are connected to the screen box by bolts. Ribs are fixed on the mounting tube. The left side of the rib is fixedly connected to the left motor base. Two first vibration motors are fixed on the left motor base. A right motor base is fixed on the right side of the rib, and a second vibration motor is fixed on the right motor base.

[0013] Specifically, the first vibration motor is a large-tonnage motor, and the second vibration motor is a small-tonnage motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the design of the threaded sleeve and bolt, the user can flexibly adjust the height of the threaded sleeve according to the spring pitch, so that the bolt can block and stabilize the spring end on one side, ensuring the stable fixation of the upper and lower ends of the spring, preventing displacement or loosening during vibration, thereby improving the overall working stability and vibration resistance of the equipment, and reducing equipment failures caused by unstable support.

[0015] 2. The power unit is equipped with a first vibration motor and a second vibration motor, which can switch the vibration trajectory according to the characteristics of the mud (such as sand content and viscosity). When the sand content is high, a linear trajectory is used to accelerate the movement of sand particles and increase the throughput; when the sand content is low and the viscosity is high, a translational elliptical trajectory is used to extend the separation time, effectively optimizing the screening process, adapting to various working conditions, and reducing mud waste.

[0016] 3. The staggered layout of the mounting units, sleeves, and bolts (with staggered threaded holes) combined with the internal spring fixing mechanism enhances the mechanical strength and wear resistance of the components. This reduces maintenance frequency, while the assembly design of the screen box and base simplifies the adjustment process and improves the long-term reliability of the equipment.

[0017] 4. The switching of vibration trajectory can optimize the screening effect for different mud conditions, which not only increases the throughput, but also reduces mud loss under fine sand and high viscosity conditions, achieving efficient resource utilization and reducing production costs.

[0018] 5. The multi-point symmetrical layout of the elastic support components, with two on each side of the screen box, combined with the balanced design of the power components, ensures that the vibrating screen remains stable during high-speed operation, reduces the risk of vibration being transmitted to the base, and extends the service life of the equipment.

[0025] 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.

[0026] Example 1: Refer to Figures 1-3 As shown, a novel dual-track vibrating screen includes a base 1 and a screen box 2, which are connected by multiple elastic support components 3.

[0027] The elastic support assembly 3 includes two mounting units arranged symmetrically at different heights, and the two mounting units are connected by a spring 306.

[0028] The mounting unit includes a mounting plate 301, on which studs 302 are fixed. The studs 302 are vertically arranged. The mounting plate 301 of the upper mounting unit is fixedly connected to the screen box 2, and the mounting plate 301 of the lower mounting unit is fixedly connected to the base 1. The bolts 305 have flat surfaces 303 machined on both the front and rear sides. The studs 302 are inserted into the end of the spring 306. Multiple threaded sleeves 304 are threadedly connected to the studs 302. The outer edge of the threaded sleeves 304 contacts the inner side of the spring 306.

[0029] The threaded sleeve 304 has a threaded hole, and the threaded holes of two adjacent threaded sleeves 304 are staggered in the front-to-back direction. Adjust the height of the threaded sleeve 304 on the stud 302, and the bolt 305 is threaded into the threaded hole. One end of the bolt 305 is tightly pressed against the plane 303 on one side. The lower bolt 305 is tightly pressed against the lower part of the spring 306 and stabilizes the lower end of the spring 306, while the upper bolt 305 is tightly pressed against the upper part of the spring 306 and stabilizes the upper end of the spring 306.

[0030] The number of elastic support components 3 is at least four. Two elastic support components 3 are provided on both the front and rear sides of the screen box 2. The two elastic support components 3 on the front side of the screen box 2 are arranged symmetrically on the left and right, and the two elastic support components 3 on the rear side of the screen box 2 are arranged symmetrically on the left and right.

[0031] When assembling the screen box 2 and the base 1, the distance between two adjacent threaded sleeves 304 is adjusted according to the pitch of the spring 306, and the threaded holes on the two adjacent threaded sleeves 304 are staggered. After the studs 302 on the upper and lower sides are respectively inserted into the upper and lower ends of the spring 306, the threaded sleeves 304 are located inside the spring 306. Then, the bolts 305 are threaded into the threaded holes. The lower bolt 305 abuts against the lower part of the spring 306 and stabilizes the lower end of the spring 306, while the upper bolt 305 abuts against the upper part of the spring 306 and stabilizes the upper end of the spring 306.

[0032] The height of the inner threaded sleeve 304 of the adjustable spring 306 is such that after the bolt 305 is installed, the bolt 305 can be tightly pressed against the spring 306.

[0033] Example 2: Based on Example 1, referring to... Figure 1 , Figure 4 and Figure 5 As shown, a power assembly is fixed inside the screen box 2. The power assembly includes a mounting frame fixed inside the screen box 2, with two first vibration motors 7 fixed on the left side of the mounting frame and one second vibration motor 8 fixed on the right side of the mounting frame.

[0034] The mounting frame includes a mounting tube 4, which is arranged longitudinally. Flanges 5 are fixed at both ends of the mounting tube 4. The flanges 5 are connected to the screen box 2 by bolts 305. Rib plates 6 are fixed on the mounting tube 4. The left side of the rib plate 6 is fixedly connected to the left motor base. Two first vibration motors 7 are fixed on the left motor base. The right side of the rib plate 6 is fixed to the right motor base. The second vibration motor 8 is fixed on the right motor base.

[0035] The first vibration motor 7 is a large-tonnage motor, and the second vibration motor 8 is a small-tonnage motor.

[0036] After the drilling mud enters the screen box 2 of the vibrating screen, it is blocked by the screen mesh inside the screen box 2. When the mud has a high sand content, the two first vibration motors 7 are started, and the screen box 2 generates a linear motion trajectory, which increases the transport speed of sand particles on the screen surface and increases the processing capacity.

[0037] When the sand content of the mud decreases, the viscosity becomes higher, and the sand particles become finer, the second vibration motor 8 is started again, and the screen box 2 generates a translational elliptical trajectory, which prolongs the sand particle separation time and thus reduces mud loss.

[0038] 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.
