Description

Technical Field

[0001] The utility model belongs to the technical field of filtering devices, and particularly relates to a vibration filtering device with multi-stage filtering. Background Art

[0002] When artificial sand is made, a vibrating screen is used to screen the crushed particles, and then sand meeting the specifications is obtained. The existing multi-stage vibrating screens for sand making usually set multiple layers of sieve plates to work with overall vibration. After the sand enters the machine box, it is filtered and screened in multiple stages from top to bottom. When only single-stage screening of the sand is required, another single-stage screening device has to be used at this time, resulting in high consumable costs, inability to be flexibly adjusted according to requirements, and low work efficiency. Therefore, a vibration filtering device with multi-stage filtering is provided herein. Content of the Utility Model

[0003] Aiming at the problems raised in the above background art, the purpose of the utility model is to provide a vibration filtering device with multi-stage filtering.

[0004] To achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0005] A vibration filtering device with multi-stage filtering includes a machine box. The machine box is detachably connected with an end cover. The end cover is connected with a feeding cylinder. One side of the bottom of the machine box is provided with a discharge opening. One side of the machine box is hinged with a switch door. Inside the machine box, a first sieve plate and a second sieve plate are connected at a certain inclination angle. Vibration motors are connected to the lower sides of both the first sieve plate and the second sieve plate. The machine box is connected with a first discharge cylinder on both sides where the angles of the first sieve plate and the second sieve plate are lower.

[0006] A motor is connected to the outer wall of the machine box. The output end of the motor is connected with a first transmission rod. An active gear is connected to the outer wall of the shaft body of the first transmission rod. The active gear meshes with a driven gear. The driven gear is connected with a second transmission rod. Third gears are connected to the outer walls of the shaft bodies of both the first transmission rod and the second transmission rod. Both of the two third gears are connected with a fourth gear through a transmission belt. The fourth gear is connected with a third transmission rod. The two third transmission rods are respectively rotatably connected to both sides of the machine box. Left and right blanking plates are respectively connected to the outer walls of the shaft bodies of both sides of the third transmission rod. A first trapezoidal clamping block is connected to the end of the left blanking plate. A second trapezoidal clamping block is connected to the right blanking plate. The length dimension of the hypotenuse of the second trapezoidal clamping block is the same as the length dimension of the bottom edge of the first trapezoidal clamping block. The machine box is connected with a second feeding cylinder beside both the left blanking plate and the right blanking plate.

[0007] Further defined, a plurality of dovetail-shaped chutes are provided at the bottom of the inner wall of the chassis, and each of the dovetail-shaped chutes is slidably connected with a matching dovetail-shaped slider. An aggregate box is connected between the plurality of dovetail-shaped sliders. The height dimension of the aggregate box is the same as the height dimension of the discharge opening. Such a structural design can facilitate material receiving and subsequent material processing.

[0008] Further defined, the feed cylinder is arranged in a hopper shape, and a dust-proof cover is hinged to one side of the feed cylinder. Such a structural design can increase the feeding area and prevent material scattering. The dust-proof cover can be closed during the screening and filtering process to prevent dust from directly floating into the air environment.

[0009] Further defined, inclined baffles are connected to both ends of the lower side of the inner wall of the end cover. Such a structural design can reduce the area where the material rebounds to the end cover and the end wall of the chassis during the filtering and screening of the material, thereby prolonging the service life.

[0010] Further defined, the second discharge cylinder is arranged in a Z shape. Such a structural design can prevent the discharge of the first discharge cylinder beside the second sieve plate from being obstructed.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. In the present invention, two vibration motors respectively drive the first sieve plate and the second sieve plate to screen and filter the material entering the chassis, achieving automatic multi-stage screening of raw materials with different particle diameters. The structure is simple and easy to operate. By opening the switch door on one side of the chassis, it is convenient to clean, unblock, repair and replace the first sieve plate and the second sieve plate;

[0013] 2. The motor connected to the chassis serves as the power end. Through transmission components such as the first transmission rod, the driving gear, the driven gear, the third gear, the second transmission rod, the conveyor belt, the fourth gear and the third transmission rod, the ends of the left blanking plate and the right blanking plate on both sides are driven to rotate towards each other with the third transmission rod as the axis. Such a structural design can automatically control the separation and splicing of the left blanking plate and the right blanking plate, meeting the requirements of the overall device for single-time multi-stage screening and filtering and single-time single-stage screening and filtering, facilitating use, and thus improving work efficiency.

[0029] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below with reference to the drawings and embodiments.

[0030] As Figures 1-3 shown, a multi-stage filtering vibration filtering device of the present utility model includes a chassis 1, the chassis 1 is detachably connected with an end cover 2, the end cover 2 is connected with a feed cylinder 201, one side of the bottom of the chassis 1 is provided with a discharge opening, one side of the chassis 1 is hinged with a switch door 1001, the inside of the chassis 1 is connected with a first sieve plate 3 and a second sieve plate 4 at a certain inclination angle, vibration motors 5 are connected to the lower sides of the first sieve plate 3 and the second sieve plate 4, and first discharge cylinders 6 are connected to the sides with lower angles of the first sieve plate 3 and the second sieve plate 4 in the chassis 1;

[0031] A motor is connected to the outer wall of the chassis 1. The output end of the motor is connected to a first transmission rod 7. The outer wall of the shaft body of the first transmission rod 7 is connected to a driving gear 701. The driving gear 701 meshes with a driven gear 702. The driven gear 702 is connected to a second transmission rod 703. The outer walls of the shaft bodies of the first transmission rod 7 and the second transmission rod 703 are both connected to third gears. Both of the two third gears are connected to a fourth gear 705 through a transmission belt 704. The fourth gear 705 is connected to a third transmission rod 706. The two third transmission rods 706 are respectively rotatably connected to both sides of the chassis 1. The outer walls of the shaft bodies of the third transmission rods 706 on both sides are respectively connected to a left blanking plate 8 and a right blanking plate 9. The end of the left blanking plate 8 is connected to a first trapezoidal clamping block 801. The right blanking plate 9 is connected to a second trapezoidal clamping block 901. The length dimension of the hypotenuse of the second trapezoidal clamping block 901 is the same as the length dimension of the base of the first trapezoidal clamping block 801. The chassis 1 is connected with a second blanking cylinder 10 beside the left blanking plate 8 and the right blanking plate 9 respectively.

[0032] In the embodiment of this case, when multi-stage filtering of sand-making raw materials is required, after the material is put into the chassis 1 from the feeding cylinder 201, the material first falls onto the first sieve plate 3 and the second sieve plate 4. By the central control, two vibration motors 5 are started. The two vibration motors 5 drive the first sieve plate 3 and the second sieve plate 4 to vibrate and filter the material at the same time. At this time, sands with different particle diameters can be screened out and classified and discharged through the first discharge cylinders 6 on both sides. Such a structural design is simple and easy to operate. By opening the switch door 1001 on one side of the chassis 1, it is convenient to clean, block, repair and replace the first sieve plate 3 and the second sieve plate 4;

[0033] It should be noted that when only single-stage filtering of the sand-making raw materials is required once, the motor is turned on through the central controller. As Figure 2 shown, the motor drives the first transmission rod 7 to rotate. When the first transmission rod 7 rotates, it drives the driving gear 701 to rotate. When the driving gear 701 rotates, it drives the driven gear 702 to rotate. When the driven gear 702 rotates, it drives the second transmission rod 703 to rotate. The first transmission rod 7 and the second transmission rod 703 drive the third gears to rotate. When the third gears on both sides rotate, they drive their respective fourth gears 705 to rotate towards each other through the transmission belt 704. When the fourth gear 705 rotates, it drives the third transmission rod 706 to rotate towards each other accordingly. When the third transmission rods 706 on both sides rotate, they drive the left blanking plate 8 and the right blanking plate 9 to rotate towards each other with them as the axis. As Figure 3As shown, until the bottom edge of the first trapezoidal clamping block 801 is fitted and connected to the upper inclined side of the second trapezoidal clamping block 901. At this time, the left blanking plate 8 and the right blanking plate 9 are spliced. When the material is put into the chassis 1 from the feeding cylinder 201, it falls onto the vibrating first sieve plate 3 for filtering and screening, and the material is directly classified into two required sand and gravel raw materials. After screening, the materials are discharged through the first discharge cylinder 6 and the two second blanking cylinders 10 on both sides. Such a structural design can automatically control the separation and splicing of the left blanking plate 8 and the right blanking plate 9, so that the whole device can automatically change the state of separation and splicing of the left blanking plate 8 and the right blanking plate 9, meet the requirements of single - time multi - stage screening and filtering and single - time single - stage screening and filtering, facilitate use, and thus improve work efficiency;

[0034] In addition, when single - stage screening is not required, control the left blanking plate 8 and the right blanking plate 9 to fit and block one side of the openings of the two second blanking cylinders 10, which does not affect the multi - stage screening and filtering process of the whole device.

[0035] Preferably, a plurality of dovetail chutes are provided at the bottom of the inner wall of the chassis 1, and each dovetail chute is slidably connected with a matching dovetail slider 101. An aggregate box 102 is connected between the plurality of dovetail sliders 101. The height dimension of the aggregate box 102 is the same as the height dimension of the discharge opening. Such a structural design can facilitate material collection and subsequent material processing. In fact, other structural shapes that are convenient for automatic centralized material collection can also be considered according to specific situations.

[0036] Preferably, the feeding cylinder 201 is of a hopper type, and a dust - proof cover 202 is hinged on one side of the feeding cylinder 201. Such a structural design can increase the feeding area and prevent material scattering. The dust - proof cover can be closed during the screening and filtering process to prevent dust from directly floating into the air environment. In fact, other structural shapes that are convenient for feeding and can prevent dust from floating in the air during processing can also be considered according to specific situations.

[0037] Preferably, two inclined baffles 203 are connected to the lower ends of both sides of the inner wall of the end cover 2. Such a structural design can reduce the area where the material rebounds to the end cover 2 and the end wall of the chassis 1 during filtering and screening of the material, and thus extend the service life. In fact, other structural shapes that can prevent material rebound and have a protective effect can also be considered according to specific situations.

[0038] Preferably, the second blanking cylinder 10 is of a Z - shape. Such a structural design can prevent interference with the discharging of the first discharge cylinder 6 beside the second sieve plate 4. In fact, other structural shapes that have a discharging effect and do not interfere with the operation of other components can also be considered according to specific situations.

[0039] The above embodiments are only used to exemplarily illustrate the principles and effects of the present invention, rather than to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
