Description

Technical Field

[0001] This utility model relates to the technical field of mud screening devices, specifically a vibrating screen for large mud particles. Background Technology

[0002] To facilitate the removal of large solid particles from the mud, a sieve is usually used for screening. For example, ceramic mud is screened using a mud vibrating screen to ensure its fineness.

[0003] While existing technologies using vibrating screens can facilitate the separation of large particles in slurry, they inevitably have shortcomings in practical use. For example, the vibration device and the frame are damped by springs, and the connection between the springs and the vibrating device and the frame is often made using lug bolts, which makes it inconvenient to disassemble the vibrating device and the frame. This leads to problems with subsequent disassembly and maintenance of the vibrating device. To avoid such problems, a vibrating screen for large particles in slurry is proposed to solve the existing problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a vibrating screen for large particles of mud, which solves the problem of the lack of a quick disassembly and assembly mechanism between the vibrating device and the frame, which makes it inconvenient to disassemble, repair, and replace the vibrating device later.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibrating screen for large particles of mud, comprising a frame and a concave assembly ring. The concave assembly ring is located at the top of the frame. A damping spring is fixedly connected between the concave assembly ring and the frame, and several damping springs are arranged equidistantly around the frame.

A funnel is fixedly connected to the bottom of the screen frame, and a vertical vibrating motor is installed at the bottom of the funnel. Several mounting grooves are equidistantly arranged around the top of the concave assembly ring. A limiting sleeve is slidably arranged inside the mounting groove. A pin is slidably connected inside the limiting sleeve, and one end of the pin extends into the interior of the concave assembly ring. A first spring is fixedly connected between the pin and the limiting sleeve. Several pin slots matching the pin are equidistantly arranged around the surface of the conical insert ring.

[0010] Beneficial effects

[0011] This invention provides a vibrating screen for large particles of mud. Compared with existing technologies, it has the following advantages: This invention, by setting a limiting sleeve, a pin, a first spring, and a pin groove between the concave assembly ring and the conical insert ring, facilitates quick installation of the screen frame through the engagement of the pin groove on the surface of the conical insert ring with the pin inside the limiting sleeve. Secondly, by setting a diagonal rod, a threaded rod, and a pressure ring between the mounting groove and the concave assembly ring, the pin groove and pin are disengaged, facilitating centralized control through the aforementioned engagement. This allows for quick and easy disassembly and assembly of the screen frame and the concave assembly ring, enabling subsequent disassembly, replacement, and maintenance of the screen frame. Furthermore, an electric telescopic rod, compatible with the concave assembly ring, is installed at the top of the frame, providing stable support for the concave assembly ring and ensuring the screen frame can be disassembled and assembled without wobbling.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-6 This utility model provides a technical solution: a vibrating screen for large particles of mud, including a frame 1 and a concave assembly ring 2, the concave assembly ring 2 being disposed on the top of the frame 1.

[0021] Furthermore: To avoid the problem of direct connection between the screen frame 4 and the shock-absorbing spring 3, which would make subsequent disassembly difficult, a shock-absorbing spring 3 is fixedly connected between the concave assembly ring 2 and the frame 1, and several shock-absorbing springs 3 are arranged equidistantly around the screen frame 2. The top of the concave assembly ring 2 is provided with the screen frame 4, and the bottom of the screen frame 4 is fixedly connected with a conical edge insert ring 5 that is matched with the concave assembly ring 2. Several ball bearings 21 are installed equidistantly around the bottom of the conical edge insert ring 5. The bottom of the screen frame 4 is fixedly connected with a funnel 6, and a vertical vibration motor 7 is installed at the bottom of the funnel 6.

[0022] Among them: in order to facilitate the stable assembly of the concave ring 2 and to facilitate the subsequent stable assembly and disassembly of the screen frame 4, electric telescopic rods 22 are fixedly connected to the front and rear sides of the top of the frame 1.

[0023] Furthermore: To facilitate quick assembly and disassembly of the screen frame 4, several mounting grooves 8 are equidistantly arranged around the top of the concave assembly ring 2. A limiting sleeve 9 is slidably arranged inside the mounting groove 8. A pin rod 10 is slidably connected inside the limiting sleeve 9, and one end of the pin rod 10 extends into the interior of the concave assembly ring 2. A first spring 11 is fixedly connected between the pin rod 10 and the limiting sleeve 9. Several pin grooves 12 that are matched with the pin rod 10 are equidistantly arranged around the surface of the conical insert ring 5. A sliding groove 18 is provided at the bottom of the mounting groove 8. A slider 19 is slidably connected inside the sliding groove 18, and the top of the slider 19 is fixedly connected to the bottom of the limiting sleeve 9. A second spring 20 is fixedly connected between the slider 19 and the sliding groove 18.

[0024] As detailed: A diagonal rod 13 is fixedly connected to the top of the limiting sleeve 9; a threaded rod 14 is rotatably provided on the top of the concave assembly ring 2 via a bearing; a pressure ring 15, which is matched with the diagonal rod 13, is threadedly connected to the surface of the threaded rod 14; a sliding rod 16 is fixedly connected to the top of the concave assembly ring 2; and a sliding hole 17 is provided on the top of the pressure ring 15 to slide and adapt to the sliding rod 16.

[0025] During installation: First, start the electric telescopic rod 22 to make the extended end of the electric telescopic rod 22 stably support the concave assembly ring 2. Then, insert the conical edge insert ring 5 at the bottom of the screen frame 4 into the concave assembly ring 2. Then, rotate the conical edge insert ring 5 to make the pin groove 12 on the surface of the conical edge insert ring 5 engage with the pin rod 10 inside the limiting sleeve 9. Then, reset the electric telescopic rod 22 and start the vertical vibration motor 7. The vertical vibration motor 7 starts to vibrate the screen frame 4. The vibration of the screen frame 4 traps large mud particles inside the screen frame 4, and the fine mud passes through the screen to the inside of the funnel 6 and is guided away.

[0026] When it is necessary to disassemble the screen frame 4: Twist the threaded rod 14 to cause the pressure ring 15 to move down. The downward movement of the pressure ring 15 compresses and expands several inclined rods 13, causing the inclined rods 13 to drive the limiting sleeve 9 and the pin rod 10 away from the pin groove 12. After the pin rod 10 is disengaged from the pin groove 12, the screen frame 4 can be pulled out of the concave assembly ring 2 as a whole.
