Description

Technical Field

[0001] The present invention relates to the technical field of vibrating screening and conveying devices, and particularly to a solid fluidized vibrating screening and conveying device. Background Art

[0002] Solid fluidization, also known as fluidization, is an operating state in which when a gas or liquid flows through a bed of solid particles at a certain velocity, the solid particles begin to loosen, suspend, and can move freely like a fluid under the action of the fluid; a solid fluidized vibrating screening and conveying device is a device that combines solid fluidization technology and vibrating screening technology, used to achieve efficient screening and conveying of solid materials, usually including a vibrating screening part and a fluidization part, and it is an efficient and stable solid material processing device, widely used in industrial fields such as chemical engineering, petroleum, and metallurgy, enabling continuous on-line separation and continuous fluidized conveying of bulk materials.

[0003] When it is necessary to assist in separating and conveying bulk materials through a solid fluidized vibrating screening and conveying device, first, the bulk raw materials are introduced into the vibrating screen main body through the feed inlet, and then the raw materials entering are screened by the vibrating screen main body, and then the raw materials are screened into small-particle-size materials and large-particle-size materials. At this time, the screened small-particle-size materials are pneumatically conveyed through the cooperation of the fluidization box and the air supply port. At this time, the large-particle-size materials are also vibrated and conveyed through the mutual cooperation of the vibrator and the fluidized bed, so that they are discharged from the discharge port, thus having three functions of vibrating screening, vibrating conveying, and pneumatic fluidized conveying; however, during the use of the vibrating screening and conveying device, the vibrator and the ground are usually fixed by bolts, which makes it difficult to move the vibrating screening and conveying device. When the factory needs to move the vibrating screening and conveying device due to adjusting the layout and configuration of the screening equipment, it is necessary to first cancel the fixation of the vibrator and the ground, and then prepare special moving tools and cranes to lift the vibrating screening and conveying device onto the moving tools for movement, with poor flexibility, which affects the utilization rate and production efficiency of the equipment, and thus affects the use of the vibrating screening and conveying device.

And the protective frame 803 is in a "U" - shaped structure. The bottom end of the second synchronous pulley 807 is connected to the base 802 through a bearing seat; both sides of the bottom end of the lifting plate 810 are welded with a transmission plate 811, and the bottom end of the transmission plate 811 is welded with a base 812. The lifting plate 810 and the transmission plate 811 are in an "L" - shaped structure, the transmission plate 811 and the base 812 are in a "T" - shaped structure, and the transmission plate 811 is in a sliding connection with the base 802; the bottom end of the base 812 is connected to a universal wheel 813, and the universal wheels 813 are distributed in a "three" - character shape. Storage cavities are opened on both sides of the bottom end of the base 802, and the base 812 extends into them. The positioning seat 801 is in a "T" - shaped structure; the adjustment mechanism 9 includes a limit seat 901, a fixing strip 902, an electric push rod 903, an extension ring 904, an extension tube 905, a limit rod 906 and a limit post 907. The bottom end of the outer wall of the discharge pipe 6 is connected to a limit seat 901, and a fixing strip 902 is welded to the bottom end of the limit seat 901; the fixing strips 902 are distributed at equal angles. Fixing holes are opened inside the bottom end of the discharge pipe 6, and the fixing strips 902 extend into them. Electric push rods 903 are installed on both sides of the top end of the limit seat 901, and the output ends of the electric push rods 903 are butted against an extension ring 904; an extension tube 905 is welded to the inner wall of the extension ring 904, and the extension tube 905 is in a sliding connection with the discharge pipe 6. Limit rods 906 are welded to both sides of the bottom end of the extension ring 904, and limit posts 907 are slidably connected to the outer walls of the limit rods 906;The bottom end of the limiting column 907 is welded to the limiting seat 901, and the electric push rod 903, the limiting rod 906 and the limiting column 907 are distributed in a "cross" shape; the inner walls of the first synchronous pulley 805 and the second synchronous pulley 807 are both connected to the synchronous belt 806, and the center lines of the extension pipe 905 and the discharge pipe 6 coincide with each other, and the first threaded rod 808 and the second threaded rod 809 are parallel to each other.;

[0025] During specific implementation, during the use of the solid fluidized vibration screening and conveying device, since the bottom end of the vibrator 1 is connected to the positioning seat 801, the positioning seat 801 is inserted into the base 802 in advance, and then the vibration screening and conveying device is placed on the top of the base 802, thereby increasing the contact area between the vibration screening and conveying device and the ground and improving its support stability;

[0026] When the vibration screening and conveying device needs to be moved due to equipment layout and configuration updates, first start the servo motor 804. Since the output end of the servo motor 804 is connected to the first synchronous pulley 805, starting the servo motor 804 will drive the first synchronous pulley 805 to rotate. And because the first synchronous pulley 805 is connected to the second synchronous pulley 807 through the synchronous belt 806, the rotation of the first synchronous pulley 805 will drive the second synchronous pulley 807 to rotate. And because the first synchronous pulley 805 is connected to the first threaded rod 808 and the second synchronous pulley 807 is connected to the second threaded rod 809, the rotation of the first synchronous pulley 805 will drive the first threaded rod 808 to rotate, and the rotation of the second synchronous pulley 807 will drive the second threaded rod 809 to rotate. And at this time, the first threaded rod 808 and the second threaded rod 809 are protected by the protective frame 803. Then, the rotation of the first threaded rod 808 and the second threaded rod 809 causes the lifting plate 810 to move smoothly downward. Since the lifting plate 810 is connected to the transmission plate 811, the movement of the lifting plate 810 will drive the transmission plate 811 to move together. After that, the movement of the transmission plate 811 drives the base 812 to move downward together. And because the base 812 is connected to the universal wheel 813, the movement of the base 812 will drive the universal wheel 813 to move together;

[0027] Until the universal wheel 813 moves out of the base 802 and contacts the ground, then an upward thrust is generated on the base 802 to make it move upward for a certain distance. At this time, the universal wheel 813 is used to assist the staff in moving the vibrating screening and conveying device, so that the staff can easily push or pull the device and move it to the designated position in a short time, thus facilitating the rapid transfer of the vibrating screening and conveying device between different working sites, meeting the needs of various working environments and scenarios, improving work efficiency. And when the vibrating screening and conveying device moves to the designated position, the universal wheel 813 can be retracted into the base 802, and then the bottom end of the base 802 contacts the ground, so that the device can be stably fixed on the ground without shaking or shifting due to the presence of the universal wheel 813, and the retracted universal wheel 813 does not occupy extra space;

[0028] Since the bottom end of the limit seat 901 is connected to the fixing strip 902, the bottom end of the limit seat 901 is attached to the bottom end of the discharge pipe 6 in advance. At this time, the fixing strip 902 is inserted into the discharge pipe 6 and is in snap connection with it, thereby fixing the limit seat 901 to prevent it from rotating randomly. Then, the electric push rod 903 is started. Since the output end of the electric push rod 903 is connected to the extension ring 904, the extension of the electric push rod 903 will drive the extension ring 904 to move upward. Then, the upward movement of the extension ring 904 will drive the extension pipe 905 to move upward together. And since the two sides of the bottom end of the extension ring 904 are welded to the limit rod 906, at this time, the limit rod 906 slides along the limit column 907, and then guides the movement of the extension pipe 905 to make it move smoothly until the extension pipe 905 moves upward to the designated position, thereby adjusting the position of the discharge port to correspond to the on-site requirements, enhancing the flexibility of the operation. Thus, when the solid fluidized vibrating screening and conveying device is used, it plays a role in facilitating the rapid transfer of the equipment and improving the flexibility.

[0029] In summary, when the solid fluidized vibration screening and conveying device is in use, bulk raw materials are first introduced into the vibration sieve main body 3 through the feed inlet 4. Then, the raw materials entering the vibration sieve main body 3 are screened, and the raw materials are thus screened into small particle size materials and large particle size materials. At this time, the small particle size materials screened out are subjected to pneumatic conveying through the cooperation of the fluidization box 5 and the air supply port 7. At this time, the large particle size materials are also subjected to vibration conveying through the mutual cooperation of the vibrator 1 and the fluidized bed 2, so that they are discharged from the discharge pipe 6. Then, it has three functions of vibration screening, vibration conveying, and pneumatic fluidization conveying, and can effectively solve the problem of insufficient installation space. This is the prior art and will not be elaborated here. The universal wheels 813 are moved out of the base 802 through the auxiliary mechanism 8 to contact the ground, so that the staff can easily push or pull the device and move it to the designated position in a short time. Then, it is convenient for the vibration screening and conveying device to quickly transfer between different working sites and meet the requirements of various working environments and scenarios. The extension pipe 905 is moved up to the designated position through the adjustment mechanism 9, so as to adjust the position of the discharge port to correspond to the on-site requirements and enhance the flexibility of the operation. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
