Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically a three-degree-of-freedom multidimensional vibrating screen. Background Technology

[0002] Currently, vibrating screens are widely used in industries such as mining, metallurgy, coal, petroleum, chemical, water conservancy and hydropower, light industry, and construction, mainly for separating materials into different particle size grades.

[0003] Most existing vibrating screens use planar vibrating motors to drive the screen frame to vibrate, thereby achieving material screening. However, planar vibrating motors can only drive the screen frame to vibrate in the XY plane. Furthermore, during the screening process, the material often clogs the screen, affecting both screening quality and efficiency. Utility Model Content

[0004] The technical problem to be solved by this invention is to overcome the existing defects and provide a three-degree-of-freedom multidimensional vibrating screen, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model discloses a three-degree-of-freedom multidimensional vibrating screen. The technical solution adopted includes a screen frame and a screen frame. The screen frame is a rectangular frame, and a feed inlet is provided at the top of the screen frame. The screen frame is provided below the feed inlet, and a screen mesh is provided on the screen frame.

[0006] The left and right sides of the screen frame are hinged to the screen frame via air dampers. The side wall of the screen frame is also equipped with a vibration motor to drive its vibration. The front and rear sides of the screen frame are also equipped with connecting blocks. Horizontal springs and suspension damping springs are respectively provided between the connecting blocks and the screen frame. By using the cooperation of a planar vibration motor and horizontal springs, vibration can be achieved in the XY plane, and rotation around the Z axis can be achieved with the support of air dampers.

[0007] The side wall of the screen frame is connected to a material guide via a pin. The material guide is located between the screen frame and the feed inlet. By setting the material guide between the screen frame and the feed inlet, it can be ensured that the material to be screened from the feed inlet falls accurately onto the screen mesh of the screen frame, avoiding the situation where the material scatters due to the vibration of the screen frame.

[0008] As a preferred embodiment of this utility model, the feeder is a shell that is open at both ends. The top of the feeder is rectangular and its cross-sectional area is larger than that of the bottom of the feed inlet. The bottom of the feeder is circular and its diameter is smaller than that of the screen frame.

[0009] As a preferred embodiment of this utility model, the vibrating motor includes a planar vibrating motor and a vertical vibrating motor. The planar vibrating motor is provided in three sets, arranged in a circular array around the axis of the screen frame. The vertical vibrating motor is provided in two sets, symmetrically mounted on the screen frame via motor mounts. By using vertical vibrating motors and suspension damping springs, vibration of the screen frame in the Z-axis direction can be achieved. The two vibration modes work together to form a three-degree-of-freedom vibrating screen, which improves both the screening efficiency and the screening quality of materials.

[0010] As a preferred embodiment of this utility model, the horizontal spring is arranged along the X-axis to generate horizontal amplitude; the suspension damping spring is arranged along the Z-axis to support the screen frame and generate amplitude in the Z-axis direction.

[0011] As a preferred embodiment of this utility model, the two ends of the air damper are connected to the screen frame and the screen holder respectively via universal joints.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model can achieve vibration in the XY plane by using a combination of a planar vibration motor and a horizontal spring, and can achieve rotation around the Z-axis under the support of an air damper. By using a vertical vibration motor and a suspension damping spring, the screen frame can be vibrated in the Z-axis direction. The two vibration modes work together to form a three-degree-of-freedom vibrating screen, which improves the screening efficiency of materials and also improves the screening quality.

[0013] In this invention, by setting a material guide between the screen frame and the feed inlet, it can be ensured that the material to be screened from the feed inlet falls accurately onto the screen mesh of the screen frame, avoiding the situation where the material scatters due to the vibration of the screen frame.

[0021] 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. Example 1

[0022] like Figures 1 to 6 As shown, this utility model discloses a three-degree-of-freedom multidimensional vibrating screen. The technical solution adopted is that it includes a screen frame 1 and a screen frame 4. The screen frame 1 is a rectangular frame, and the top of the screen frame 1 is provided with a feed inlet 2. The screen frame 4 is provided below the feed inlet 2, and the screen frame 4 is provided with a screen mesh 13.

[0023] The left and right sides of the screen frame 4 are hinged to the screen frame 1 via air vibration dampers 3.

[0024] like Figure 5 As shown, the two ends of the air damper 3 are connected to the screen frame 4 and the screen holder 1 respectively via universal joints 5.

[0025] The side wall of the sieve frame 4 is also equipped with a vibration motor to drive its vibration. The vibration motor includes a planar vibration motor 9 and a vertical vibration motor 11.

[0026] The planar vibration motor 9 is a vertical vibration motor. There are three sets of planar vibration motors 9 arranged in a circular array around the axis of the screen frame 4. The three sets of planar vibration motors 9 rotate synchronously in the same direction, which can realize the vibration of the vibrating screen in the X-axis direction.

[0027] The vertical vibration motor 11 is a horizontal vibration motor. There are two sets of vertical vibration motors 11, which are symmetrically installed on the screen frame 4 through the motor base 10. The two vertical vibration motors 11 rotate synchronously in opposite directions, which can realize the vibration of the vibrating screen in the Z-axis direction.

[0028] The screen frame 4 is also provided with connecting blocks 12 on the front and rear sides, and a horizontal spring 7 and a suspension damping spring 8 are respectively provided between the connecting blocks 12 and the screen frame 1.

[0029] The horizontal spring 7 is arranged along the X-axis and is used to generate horizontal amplitude; the suspension damping spring 8 is arranged along the Z-axis and supports the screen frame 4 while also generating amplitude in the Z-axis direction.

[0030] The side wall of the screen frame 4 is connected to a feed guide 6 via a pin 14, and the feed guide 6 is located between the screen frame 4 and the feed inlet 2.

[0031] The feed guide 6 is a shell that is open at both ends. The top of the feed guide 6 is rectangular and its cross-sectional area is larger than that of the bottom of the feed inlet 2. The bottom of the feed guide 6 is circular and its diameter is smaller than that of the screen frame 4, so that the material can fall smoothly onto the screen mesh 13 of the screen frame 4.

[0032] The working principle of this utility model is as follows: When in use, first turn on the power supply, then check whether each component is normal. After the check is completed, pour the material to be screened into the feed port 2 of the screen frame 1, start the planar vibration motor 9, and under the action of the air damper 3, the universal shaft 5 and the horizontal spring 7, the screen frame 4 makes a small-amplitude reciprocating rotation around the Z axis on the XY plane, while driving the horizontal spring 7 to generate horizontal lateral vibration.

[0033] Under the action of the vertical vibration motor 11, vertical vibration is generated through the suspension damping spring 8. At the same time, the suspension damping spring 8 and the air damper 3 can also play a certain role in damping, ensuring that the entire mechanism can operate smoothly.

[0034] The material screened by screen 13 falls into the receiving trolley located below the screen frame 4. After the entire screening process is completed, the screened product is transported out by the receiving trolley. Different particle sizes of material can also be screened by changing screen 13 of different sizes.

[0035] The circuits and mechanical connections involved in this utility model are common practices used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. They are common knowledge.

[0036] Components not described in detail in this article are existing technologies.

[0037] 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.
