Description

Technical Field

[0001] This utility model relates to the field of quartz sand screening technology, and in particular to an automated vibration screening device for quartz sand. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Quartz sand is an important industrial mineral raw material and an important raw material for glass. In the process of producing quartz sand suitable for the glass industry, it is necessary to grind the quartz sand into fine particles or powder.

[0003] A search revealed that the document with publication number "CN218014049U" mentions "This utility model discloses a quartz sand grading and screening device, which includes: a fixed box, a screen slidably connected to the side wall of the fixed box, a sliding plate provided on the upper surface of the screen, and a first threaded post threadedly connected to the side wall of the screen; an electric push rod, a connecting post rotatably connected to the movable end of the electric push rod, a fourth threaded post fixedly connected to the side wall of the connecting post, a groove opened in the inner wall of the fixed box, a moving plate slidably connected inside the groove, a through groove opened in the side wall of the moving plate, and threaded holes opened in the side walls of the fixed box and the moving plate; a fixed plate fixedly connected to the lower surface of the fixed box, and a vibration motor fixedly connected to the upper surface of the fixed plate." In use, the electric push rod moves the fourth threaded post into the screen, then into the sliding plate, and then the electric push rod returns, thereby pushing the sand and gravel out of the screen, making it convenient to push the sand and gravel out.

[0004] However, existing screening devices typically use a motor to vibrate the entire device to meet screening requirements. However, this vibration method causes the entire device to shake significantly, resulting in noise. Furthermore, existing devices, except for the screen, are usually a large unit, making them inconvenient to maintain.

[0005] Therefore, we provided an automated vibrating screening equipment for quartz sand to solve the above problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides an automated vibration screening device for quartz sand, which aims to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automated vibrating screening device for quartz sand includes a mounting frame. A mounting ring frame is welded to the bottom inner side of the top of the mounting frame. A splicing screening assembly is provided on the upper side of the mounting ring frame. The splicing screening assembly includes a support ring frame installed at the top of the mounting ring frame. A splicing frame is provided above the support ring frame. A splicing top frame is provided above the splicing frame. A vibration connecting block is welded to the upper inner wall of the splicing top frame.

[0009] As a further description of the above technical solution:

[0010] The support ring frame is made of stainless steel. Support springs are fixedly connected to the inner side of the support ring frame. There are twelve sets of support springs, which are evenly distributed at equal intervals inside the support ring frame.

The upper and lower surfaces of the support ring frame are welded with connecting strips. The size of the mounting groove matches the size of the connecting strip.

[0013] As a further description of the above technical solution:

[0014] The splicing frame is modularly designed, and a primary screen is welded to the inner side of the splicing top frame. A support ring frame is also installed between the splicing top frame and the splicing frame.

[0015] As a further description of the above technical solution:

[0016] Both the primary and secondary screens are made of stainless steel, and the mesh size of the primary and secondary screens decreases progressively.

[0017] As a further description of the above technical solution:

[0018] Both the top splicing frame and the splicing frame have a butt ring plate welded to their bottom ends. The diameter of the butt ring plate is smaller than the inner diameter of the top splicing frame and the splicing frame, and the height of the butt ring plate is greater than the height of the supporting ring frame.

[0019] As a further description of the above technical solution:

[0020] The mounting frame is welded with a mounting column on the outside. An electrically controlled lifting rod is installed at the top of the mounting column. A connecting top plate is welded to the end of the electrically controlled lifting rod. A servo motor is fixedly installed on the inner side of the connecting top plate. A vibration pressure plate is connected to the output end of the servo motor. The vibration pressure plate has an eccentric cam structure.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] By setting up a splicing screening component, and utilizing the cooperation of support ring frame, support spring, connecting strip, mounting groove, splicing frame, primary screen and secondary screen, screens with different mesh sizes can be selected and spliced ​​together according to the size of the quartz sand particles to achieve multi-stage screening, thereby improving screening efficiency and accuracy. At the same time, both the splicing frame and the splicing top frame are modularly designed, which facilitates the replacement and maintenance of the screens and reduces the cost of use.

[0023] By setting up an electrically controlled lifting rod, connecting top plate, servo motor and vibrating pressure plate, the servo motor drives the vibrating pressure plate to reciprocate. The vibrating pressure plate corresponds one-to-one with the vibrating connecting block, so that the splicing screening component as a whole vibrates, thereby achieving effective screening of quartz sand. At the same time, under the action of the bottom support spring, the transmission of vibration outward is reduced, thus avoiding large shaking of the whole device and reducing the overall vibration and noise of the equipment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: an automated vibratory screening device for quartz sand, including a mounting frame 1, a mounting ring frame 2 welded to the bottom of the inner side of the top of the mounting frame 1, a splicing screening component 3 provided on the upper side of the mounting ring frame 2, the splicing screening component 3 including a support ring frame 301 installed on the top of the mounting ring frame 2, a splicing frame 304 provided above the support ring frame 301, a splicing top frame 307 provided above the splicing frame 304, and a vibration connecting block 4 welded to the upper side of the inner wall of the splicing top frame 307.

[0033] Furthermore, the support ring frame 301 is made of stainless steel, and a support spring 302 is fixedly connected to the inner side of the support ring frame 301. There are twelve sets of support springs 302, which are evenly distributed at equal intervals inside the support ring frame 301. During use, the splicing frame 304 is supported and installed through the support ring frame 301. At the same time, the support ring frame 301 is made of stainless steel, which has excellent corrosion resistance and wear resistance, and can extend the service life of the equipment.

[0034] Furthermore, a secondary screen 305 is fixedly connected to the inner side of the splicing frame 304. The upper and lower surfaces of the splicing frame 304 are provided with mounting grooves 306. The upper and lower surfaces of the support ring frame 301 are welded with connecting strips 303. The size of the mounting groove 306 matches the size of the connecting strip 303. The splicing frame 304 and the splicing top frame 307 are connected to the support ring frame 301 through the connecting strips 303 and the mounting grooves 306. This modular design makes the assembly and disassembly of the equipment more convenient and quick, and also facilitates the maintenance and replacement of parts.

[0035] Furthermore, the splicing frame 304 is modularly configured, and a primary screen 308 is welded to the inner side of the splicing top frame 307. A support ring frame 301 is also installed between the splicing top frame 307 and the splicing frame 304. Through the modular configuration, different numbers of splicing frames 304 can be installed according to the screening requirements, thereby forming a multi-stage screening of quartz sand. At the same time, the support ring frame 301 can make multiple sets of splicing frames 304 vibrate together to ensure the vibration screening effect of quartz sand.

[0036] Furthermore, both the primary screen 308 and the secondary screen 305 are made of stainless steel. The mesh size of the primary screen 308 and the secondary screen 305 decreases progressively. The design of the primary screen 308 and the secondary screen 305 enables the grading and screening of quartz sand. During use, larger quartz sand particles are intercepted by the primary screen 308, while smaller particles pass through the primary screen 308 and fall onto the secondary screen 305 for further subdivision, thus improving the screening effect of quartz sand.

[0037] Furthermore, both the splicing top frame 307 and the splicing frame 304 are welded with a butt ring plate 309 at their bottom ends. The diameter of the butt ring plate 309 is smaller than the inner diameter of the splicing top frame 307 and the splicing frame 304, and the height of the butt ring plate 309 is greater than the height of the supporting ring frame 301. The setting of the butt ring plate 309 can ensure that the splicing frame 304 and the splicing top frame 307 will not shift during vibration, thus ensuring the stability of the equipment. At the same time, it can prevent the quartz sand from popping out of the screen during vibration screening, thus ensuring the safety of vibration screening.

[0038] Furthermore, mounting columns 5 are welded to the outer side of the mounting frame 1. An electrically controlled lifting rod 6 is installed at the top of the mounting column 5. A connecting top plate 7 is welded to the end of the electrically controlled lifting rod 6. A servo motor 8 is fixedly installed on the inner side of the connecting top plate 7. A vibration pressure plate 9 is connected to the output end of the servo motor 8. The vibration pressure plate 9 has an eccentric cam structure. The position of the vibration pressure plate 9 corresponds one-to-one with the position of the vibration connecting block 4. In use, the position of the vibration pressure plate 9 is adjusted by the electrically controlled lifting rod 6 according to the overall height of the splicing top frame 307, so that the vibration pressure plate 9 is attached to the vibration connecting block 4. Then, the servo motor 8 is started to drive the vibration pressure plate 9 to rotate. In this way, the vibration pressure plate 9 with the eccentric cam structure intermittently presses down on the vibration connecting block 4. When the vibration connecting block 4 is under force, the support spring 302 will continuously contract and then bounce back under force, thereby intensifying the vibration screening of the quartz sand. At the same time, under the action of the support spring 302, the outward transmission of vibration will be reduced, thus avoiding large shaking of the whole device and reducing the overall vibration and noise generation of the equipment.

[0039] Working Principle: Move the device to the working position, then fix the mounting bracket 1 in the designated position. Next, connect the external power supply to ensure both the electrically controlled lifting rod 6 and the servo motor 8 are operational. In use, first pour the quartz sand raw material into the splicing top frame 307. Then, adjust the position of the vibrating pressure plate 9 according to the overall height of the splicing top frame 307 using the electrically controlled lifting rod 6, ensuring the vibrating pressure plate 9 adheres to the vibrating connecting block 4. Then, start the servo motor 8; the output shaft of the servo motor 8 drives the vibrating pressure plate 9 to rotate. Because the vibrating pressure plate 9 has an eccentric cam structure, it intermittently presses down on the vibrating connecting block 4. When the vibrating connecting block 4 is under force, it is supported by... The ring frame 301 transmits force to the support spring 302. At this time, the support spring 302 will continuously contract and then bounce back under force, so that the splicing top frame 307 and the splicing frame 304 vibrate together, thereby vibrating and screening the quartz sand. At the same time, the support spring 302 at the bottom layer will reduce the outward transmission of vibration force, preventing the whole device from shaking significantly. During this process, larger quartz sand particles will be intercepted by the primary screen 308, while smaller particles will fall onto the secondary screen 305 through the primary screen 308 for further subdivision. The screened quartz sand will leak out from the bottom of the mounting frame 1, thus completing the use of the automated quartz sand vibrating screening equipment.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
