Description

Technical Field

[0001] The present application relates to the field of vibrating screen dust collection structures, and in particular to a vibrating screen dust collection device. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. However, after the ore is mined, dirt and dust adhere to its surface and it needs to be screened. During the screening process, the dry environment and the separation of mud and sand easily cause a large amount of dust to fly. The existing vibrating screen dust collection device usually transports the stone into a closed shell for infusion of cold air to guide the flow to achieve the dust collection effect.

[0003] For example, patent number CN201920793178.4, a carbon black vibrating screen dust suction and cooling device, has the following deficiencies in actual use:

[0004] The device transports stones into the screen box, and then the vibration of the vibrating motor shakes off the mud and sand between the stones to raise dust. The raised dust is discharged by the cold air pipe, thereby achieving the dust collection effect. However, the raised dust is light in weight and the space in the screen box is small. The dust is usually easily separated from the cold air, and floats upward and is discharged to the outside of the device through the feed hopper. The stone cannot be effectively dusted. At the same time, as the dust floats out and attaches to the parts of the device, it is easy to affect the service life of the device and the health of personnel. Utility Model Content

[0038] The following is combined with Figure 1 —5 Further details of this application are provided.

[0039] The embodiment of the present application discloses a vibrating screen dust collection device.

[0040] Example 1

[0041] Reference Figure 1 , 3 A vibrating screen dust collecting device includes a main frame 1, which is U-shaped as a whole, and has slide grooves 12 around the upper and lower ends of the inner surface. The two slide grooves 12 pass through the outer surface of the main frame 1. Two connecting holes 9 (a total of eight connecting holes 9) are opened on both sides, and a vibration hole 10 is opened between the connecting holes 9 on one side of the main frame 1. Annular abutment blocks 21 are movably abutted in the two slide grooves 12, and a vibration gap of 2 to 3 cm is reserved between the abutment blocks 21 and the slide grooves 12. Screen plates 2 are fixed on the inner surfaces of the two abutment blocks 21. Connecting blocks 22 are protrudingly provided at the positions where the outer surfaces of the two abutment blocks 21 are aligned with the connecting holes 9, and force blocks 23 are protrudingly provided at the positions where the outer surfaces of the connecting blocks 22 are aligned with the vibration holes 10.

[0042] It should be noted that sieve holes are provided on the surface of the sieve plate 2, and the aperture range of the sieve holes is adjusted according to the screened material. A collecting device is provided directly below the two sieve plates 2. At the same time, the connecting block 22 is movably connected to the connecting hole 9, and the force-bearing block 23 is movably connected to the vibration hole 10.

[0043] Through the above arrangement, the force-bearing block 23 receives the vibration force and vibrates in the vibration hole 10, while transmitting the vibration force to the abutment block 21 and the connecting block 22. The abutment block 21 receives the vibration and reciprocates up and down along the top and bottom ends of the slide groove 12. The screen plate 2 is fixedly connected to the abutment block 21 so as to reciprocate synchronously to form an overall vibration effect.

[0044] Reference Figure 1 , 2 4. The dust suction mechanism 3 includes an exhaust shell 31 glued and fixedly mounted on the upper inclined surface of the main frame 1. The outer side surface of the exhaust shell 31 is set as a folding surface that can be compressed and stretched. An air inlet groove 32 is provided on one side of the bottom surface of the exhaust shell 31. The air inlet groove 32 connects the inside and outside of the exhaust shell 31 cavity. An air outlet hole 33 is provided on the other end of the upper end surface of the exhaust shell 31 located at the air inlet groove 32. The air outlet hole 33 runs through the exhaust shell 31 cavity, and an air outlet pipe 34 is glued and fixedly mounted on the outer surface of the air outlet hole 33. A filter screen 35 is glued and fixedly mounted on one end of the air outlet pipe 34 away from the air outlet hole 33. A filter cotton 36 is fixedly mounted between the air inlet groove 32 and the air outlet hole 33 in the cavity of the exhaust shell 31. An extrusion plate 37 (with a position of 1 / 4" on the left side of the air inlet groove 32) is arranged around the outer surface of the exhaust shell 31. Figure 1 , 4 as reference standard).

[0045] It should be noted that the filter cotton 36 has through holes on its surface, and a coating mixed with water and adhesive is poured into the through holes to absorb dust in the air. At the same time, grooves are provided at both ends of the bottom of the extrusion plate 37, and the two ends of the bottom of the extrusion plate 37 are respectively fixedly connected to the connection blocks 22 at the aligned position.

[0046] Through the above arrangement, the extrusion plate 37 is vibrated by the connecting block 22 to move up and down, thereby applying pressure back and forth to the left side of the vacuum shell 31 to produce a pressing effect. The left side of the vacuum shell 31 is pressed to push the air in the vacuum shell 31 forward, and the air is filtered by the filter cotton 36 and enters the air outlet 33, and then enters the air outlet pipe 34 to be filtered for the second time by the filter screen 35 and then discharged to the outside. As the extrusion plate 37 moves upward, the vacuum shell 31 rebounds and expands the space in the cavity to form pressure, so that the air on the surface of the sieve plate 2 is drawn into the vacuum shell 31 to complete the filtering operation.

[0047] Reference Figure 2 , 5 The front column structure 4 is screwed to the front pillars 41 on both sides of the outer surface of the main frame 1, and the upper end surfaces of the two front pillars 41 are welded and fixed with front lower rods 42, and the tops of the two front lower rods 42 are welded and fixed with front upper rods 44, and the surfaces of the front lower rods 42 and the front upper rods 44 are fixed with springs, and the surfaces of the two front lower rods 42 are movably plugged with front sliders 43, and the two front sliders 43 are fixed one by one with the connecting blocks 22 on the opposite side, and the bottom of the front sliders 43 is fixed with the top of the spring, and the tops of the two front upper rods 44 are provided with first limit blocks 45, and the surfaces of the two front upper rods 44 are movably plugged with the grooves of the extrusion plate 37, and the bottom surfaces of the two ends of the extrusion plate 37 are fixed with the top of the spring (when the extrusion plate 37 is connected to the front upper rod 44, a vibration space of 2 to 3 cm is reserved between the groove of the extrusion plate 37 and the first limit block 45, such as Figure 2 shown).

[0048] Through the above arrangement, the front sliding block 43 and the extrusion plate 37 move up and down due to the vibration of the connecting block 22. At the same time, the front sliding block 43 and the extrusion plate 37 are fixed to the spring so as to reciprocate along the surface of the front lower rod 42 and the front upper rod 44, thereby increasing the vibration amplitude of the screen plate 2. At the same time, the first limit block 45 is located in the groove of the extrusion plate 37 to limit the movement of the extrusion plate 37.

[0049] Reference Figure 2 , 5 The rear pillar structure 5 includes rear pillars 51 welded and fixed on both sides of the main frame 1 at the other end relative to the front pillars 41, the tops of the two rear pillars 51 are welded and fixed with rear lower rods 52, the tops of the two rear lower rods 52 are welded and fixed with rear upper rods 53, the tops of the two rear upper rods 53 are welded and fixed with second limit blocks 54, springs are fixed on the surfaces of the rear lower rods 52 and the rear upper rods 53, rear sliders 55 are movably inserted on the surfaces of the rear lower rods 52 and the rear upper rods 53, and the two rear sliders 55 are fixed one by one to the tops of the two springs, and the two rear sliders 55 are fixed one by one to the connecting blocks 22 on the opposite side.

[0050] Through the above arrangement, the two rear sliders 55 move up and down due to the vibration of the connecting block 22. At the same time, the two rear sliders 55 are fixed to the springs so as to reciprocate along the surfaces of the rear lower rod 52 and the rear upper rod 53, cooperating with the movement of the front slider 43 and the extrusion plate 37 to assist in amplifying the vibration of the two screen plates 2.

[0051] Reference Figure 2 A vibration column 6 is welded and fixed on one side of the outer surface of the main frame 1 between the front support 41 and the rear support 51. A spring is fixed on the top of the vibration column 6. The top of the spring is fixedly connected to a vibration plate 7. The side of the vibration plate 7 close to the main frame 1 is fixedly connected to two force blocks 23. The side of the vibration plate 7 away from the force blocks 23 is fixedly provided with a vibration motor 8.

[0052] Through the above arrangement, the vibration motor 8 increases the vibration and transmits it to the vibration plate 7. The vibration plate 7 connects the two force blocks 23 and applies vibration. At the same time, the bottom of the vibration plate 7 is connected to the vibration column 6 through a spring, so that it reciprocates up and down rebounding motion around the vibration column 6.

[0053] Reference Figure 3 Baffles 11 are rotatably provided on both sides of the inner wall of the main frame 1. A material receiving plate 13 is fixedly provided on the right side of the baffle 11. A groove is provided in the middle of the material receiving plate 13, and a fan 14 is fixedly provided in the groove. An air outlet groove 15 is provided on the left side of the baffle 11 of the main frame 1. A plurality of dust suction rods 16 (the number of dust suction rods 16 is at least 4) are plugged and fixed in the air outlet groove 15. The spacing between the plurality of dust suction rods 16 is less than 5 mm, and a layer of rubber silicone material is provided on the surface of the dust suction rods 16.

[0054] It should be noted that the air outlet of the fan 14 is located between the two sieve plates 2, and the casing of the fan 14 is provided with a protective cover for filtering dust.

[0055] Through the above arrangement, personnel adjust the angles of the two baffles 11 to control the rolling speed of the material on the surface of the sieve plate 2. At the same time, the fan 14 blows the air between the two sieve plates 2, so that the air flows to the air outlet groove 15 and is adsorbed by the dust suction rod 16, thereby forming a filtering and dust suction effect.

[0056] Among them, the device also includes a microcomputer, a protective cover, a vibration motor 8 and a fan 14, which are all existing technologies, and their structural principles are not described in detail.

[0057] The implementation principle of a vibration screen dust collection device in the embodiment of the present application is as follows: when using the device, a person operates a microcomputer to control the vibration motor 8 to start, and the vibration motor 8 drives the vibration plate 7 to vibrate. The vibration plate 7 is connected by a spring to move up and down with the vibration column 6 as the center. At the same time, the vibration plate 7 transmits the vibration force to the two force blocks 23, and then the force blocks 23 drive the abutment blocks 21 and the screen plate 2 to vibrate. At this time, the material is poured from the top plane of the main frame 1 to the surface of the screen plate 2 to screen the material;

[0058] As the material and the sieve plate 2 vibrate and rub, the generated dust floats upward to the bottom of the exhaust shell 31. At this time, the connecting block 22 is driven by the abutment block 21 to vibrate synchronously, thereby driving the extrusion plate 37 to move back and forth along the surface of the front upper rod 44. When the extrusion plate 37 moves downward along the front upper rod 44, the extrusion plate 37 squeezes one end of the exhaust shell 31, thereby squeezing the air in the exhaust shell 31 out of the air outlet 33. The squeezed air is filtered when it passes through the filter cotton 36, and the dust particles in the air are adsorbed. Then the air is discharged from the outlet pipe 34, filtered by the filter screen 35 for the second time, and finally discharged to the outside. When the extrusion plate 37 moves upward along the front upper rod 44, the exhaust shell 31 rebounds to expand the space in the cavity, generating pressure to absorb the air above the sieve plate 2, and the air discharged from above is dust-absorbed in this reciprocating manner.

[0059] When the material is screened by the first layer of sieve plate 2 and then falls into the second layer of sieve plate 2 for screening, a small amount of dust will still be excited. At this time, the microcomputer controls the fan 14 to start, and the fan 14 blows the air between the two sieve plates 2, so that the air is blown into the air outlet groove 15 and is adsorbed by the dust suction rod 16, so as to filter the residual dust. This solves the problem that dust generated during material screening interferes with the normal operation of the machine and affects the health of personnel.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
