Description

Technical Field

[0001] The utility model relates to the technical field of mud vibrating screens, in particular to a mud vibrating screen device. Background Technique

[0002] The mud vibrating screen is a mechanical device designed specifically for screening and separating mud, wet granular materials, or materials containing a certain amount of moisture and viscosity. It is widely used in multiple industries such as ceramics, mining, chemical engineering, construction, and metallurgy, especially for pre-treating raw materials to ensure the material purity and particle size requirements in the subsequent processing process. The working principle and characteristics of the mud vibrating screen mainly include the following points: Working Principle 1. Vibration source: The mud vibrating screen usually uses a vibration motor as the vibration source. The vibration motor generates a directional exciting force through rotation, causing the screen surface to produce linear vibration, circular vibration, or complex trajectory vibration. 2. Screening process: When the mud containing different particle sizes passes through the screen mesh, under the action of the vibration force, the particles smaller than the mesh size pass through the screen holes, while the particles larger than the mesh size remain on the screen surface, realizing the classification and separation of the materials. 3. Screen mesh structure: Equipped with screen meshes of different mesh numbers (pore sizes), different particle size materials can be screened out according to needs. The screen mesh material needs to be wear-resistant and corrosion-resistant to adapt to the properties of the mud. Equipment Characteristics 1. High-efficiency screening: By adjusting the vibration frequency and amplitude, the screening efficiency can be effectively improved, and even highly viscous mud can be effectively separated. 2. Adjustable: The vibration parameters (such as amplitude, frequency) are adjustable to adapt to different material characteristics and screening requirements. 3. Anti-blocking design: In view of the viscous characteristics of the mud, the equipment is designed with a mechanism to prevent material blockage, such as a bouncing ball cleaning system or a special screen mesh design, to maintain the screening efficiency. 4. Easy to maintain: Adopting a modular design, it is convenient to replace the screen mesh and carry out maintenance, reducing the downtime. 5. Enclosed structure: Most mud vibrating screens adopt a fully enclosed or semi-enclosed structure, reducing environmental pollution, keeping the working environment clean, and also helping to reduce noise. 6. Wear-resistant materials: The parts in contact with the materials are made of wear-resistant materials to extend the service life of the equipment. 7. Automatic discharging: Designed with an automatic discharging device to ensure continuous operation and improve production efficiency. The mud vibrating screen plays an important role in improving production efficiency, ensuring product quality, and reducing the labor intensity of workers, and is one of the indispensable pre-treatment equipment in modern industrial production.

[0003] In the prior art, mainly the method of vibrating the vibrating screen is adopted to realize the screening and vibration of the mud; however, since the mud may cause blockage of the screen holes during the long-term simple vibration process, once blockage occurs, the screen plate needs to be removed and cleaned, greatly reducing the use efficiency of the device. Summary of the Invention

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a mud vibrating screen device.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0007] A cyclic overturning swing assembly, which includes a sieve plate arranged at the bottom of the outer box. The surface of the sieve plate is provided with sieve holes. Plug rods are rotatably installed on both sides of the outer box. A pendulum is installed on one side of the plug rod, and a motor is installed on one side of the pendulum;

[0008] A vibration structure, which includes a ram installed on one side of the outer box, and a drive is installed on one side of the ram;

[0017] Compared with the prior art, the utility model provides a mud vibrating screen device, which has the following beneficial effects:

[0018] Through the mutual cooperation of the set cyclic subversive swing component, sieve hole adjustment component and vibration structure, the effect of multi-functional anti-blockage at the sieve hole part is achieved. Among them, the cyclic subversive swing component adopts the "∞" type operation vibration sieve operation trajectory, thereby avoiding the material from regularly falling into the inside of the sieve hole due to simple harmonic vibration and forming a blockage; this operation trajectory makes the material not easy to generate turbulence, so the problem of accumulation at the sieve hole part is reduced. By pulling the slide plate inside the chute, the adjustment holes on the surface of the slide plate are misaligned with the sieve holes, which can be used to adjust the aperture of the sieve holes, thereby reducing the possibility of blockage. The vibration structure realizes the takeoff of the blocked material at the sieve hole part by the impact hammer hitting the outer box, thereby increasing the cleaning effect.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Embodiment 1: Refer to Figure 1 - Figure 4 , a mud vibrating screen device, including an outer box 1. The function of the outer box 1 is to prevent the mud from leaking during the vibration screening process. It also includes:

[0028] The cyclic subversive swing component 2 makes the overall sieve structure present an operating path of an "∞" trajectory. Cooperating with the adjacent impact component, it makes the operating trajectory of the sieve irregular, thereby reducing the risk of blockage at the sieve hole 6. The cyclic subversive swing component 2 includes a sieve plate 5 arranged at the bottom of the outer box 1. The sieve hole 6 on the surface of the sieve plate 5 is the part directly screening the mud. The sieve holes 6 are arranged on the surface of the sieve plate 5. Plug rods 7 are rotatably installed on both sides of the outer box 1. The plug rods 7 rotate inside the outer box 1, so that the plug rods 7 can drive the sieve to turn over. A pendulum 8 is installed on one side of the plug rod 7. The motor 9 drives the pendulum 9 to rotate, so that the plug rod 7 pulls the end of the outer box 1 to achieve circular rotation. Since the installation directions of the pendulums on both sides are opposite, the outer box 1 in the middle presents an "∞" - shaped operating trajectory. A motor 9 is installed on one side of the pendulum 8;

[0029] The vibration structure 4, together with the above - mentioned trajectory operation structure, realizes the irregular vibration of the outer box 1, thereby reducing the risk of blockage at the sieve hole 6. The vibration structure 4 includes a ram 14 installed on one side of the outer box 1. The ram 14 rotates under the control of the driver 15, and then impacts the outer box 1, making the outer box 1 present a vibration effect to avoid the initial appearance of blockage. A driver 15 is installed on one side of the ram 14;

[0030] The pendulums 8 are arranged in an array on both sides of the outer box 1. The pendulums 8 on both sides are installed in opposite directions in the initial state. Installing in opposite directions can make the outer box 1 present an operating trajectory of an "∞" path.

[0031] A mud vibrating sieve device further includes:

[0032] The sieve hole adjusting structure 3 is a component for adjustment after the sieve hole 6 is blocked. The sieve hole adjusting structure 3 includes a sliding groove 10 opened on one side of the outer box 1. A sliding plate 11 can be pulled in and out inside the sliding groove 10, so that the adjusting hole 13 is misaligned with the sieve hole 6, and then the stones at the blocked part are separated from the sieve hole. The sliding plate 11 is slidably installed inside the sliding groove 10. An adjusting hole 13 is arranged at the position corresponding to the sieve hole 6 on the surface of the sliding plate 11.

[0033] For a mud vibrating sieve device, a limiting plate is arranged on one side of the sliding plate 11. The function of the limiting plate is to prevent the sliding plate 11 from slipping.

[0034] For a mud vibrating sieve device, a pull rod 12 is arranged on one side of the sliding plate 11. The function of the pull rod 12 is to control the moving effect of the sliding plate 11.

[0035] For a mud vibrating sieve device, the apertures of the sieve hole 6 and the adjusting hole 13 are kept the same. During the misalignment process, the probability of the blockage being separated can be increased.

[0036] In the actual design process of the present utility model, in order to solve the following technical defects existing in the prior art: "In the prior art, the screening and vibration of the mud material are mainly achieved by the vibration of a vibrating screen; however, since the mud material may cause the clogging of the sieve holes during the long-term simple vibration process, once clogging occurs, the sieve plate needs to be removed and cleaned, greatly reducing the use efficiency of the device." The cyclic subversive swing assembly 2, the sieve hole adjustment structure 3, and the vibration structure 4 are specifically proposed. The cyclic subversive swing assembly 2 drives the pendulum 8 to rotate through the motor 9 on the side, and the pendulum 8 drives the transmission of the plug rod 7 at the end, thereby realizing the takeoff effect at the edge part of the sieve box. The pendulums 8 on both sides are respectively arranged in opposite directions, enabling the outer box 1 in the middle part to achieve the running effect of an "∞" trajectory. This running trajectory enables the materials in the outer box 1 in the middle part to form an irregular movement effect under the cooperation of the vibration structure 4, thereby avoiding the movement of the logistics along a fixed trajectory caused by conventional simple harmonic vibration and thus clogging on the surface of the sieve holes.

[0037] When the device still gets clogged, we pull the slide plate 11 inside the sliding groove 10. The adjustment holes 13 provided on the slide plate 11 will continuously be misaligned with the sieve holes, thereby increasing the anti-clogging effect; finally, the rammer 14 is controlled by the driver 15 to impact the box body, further increasing the sieve hole cleaning effect.

[0038] Embodiment 2: Refer to Figure 5 , a mud material vibrating screen device, further comprising:

[0039] Working principle: The auxiliary stirring assembly, the main function of this assembly is to assist in achieving the vibrating screen effect by increasing the degree of chaos of the mud material and avoiding the occurrence of clustering. The auxiliary stirring assembly includes a frame 16, and a rotor 17 is installed in the middle part of the frame 16. The rotor 17 drives the stirring blade 19 at the end of the control rod 18 to stir inside the outer box 1, thereby avoiding the clustering of the mud material at the sieve hole part and thus preventing the problem of filtration failure. A rod 18 is provided at the output end of the rotor 17, and a stirring blade 19 is provided at the end of the rod 18.
