Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a compound vibrating screen. Background Art

[0002] A vibrating screen is a mechanical device widely used in multiple industries such as mineral processing, chemical industry, construction, metallurgy, food processing, etc. Its main functions are to screen, classify, dehydrate, deslime and remove impurities from bulk materials.

[0003] The vibrating screen mainly relies on the reciprocating or rotational vibration generated by the vibrator to make the materials on the screen surface jump or slide along the screen surface, thereby achieving the separation of large and small particles. Specifically, the vibrators in the screen body (usually including an upper rotating weight and a lower rotating weight) rotate under the drive of the motor. The upper weight makes the screen surface generate planar gyratory vibration, while the lower weight generates conical gyratory vibration. The combined force of the two forms a complex rotary vibration trajectory.

[0004] Under the action of vibration, the particles smaller than the screen holes fall through the screen holes, while the particles larger than the screen holes remain on the screen surface, achieving the classification of materials.

[0005] In mining, vibrating screens are widely used for the preliminary screening and beneficiation classification of raw ore.

[0006] However, the existing vibrating screens usually include a frame, a screen hopper and a vibrator connected to the screen hopper. The vibrator is directly fixed between the screen hopper and the frame. Such a structure limits the installation position of the vibrator, making the loading and unloading of the vibrator inconvenient.

[0007] Moreover, since the screen hopper is of a cylindrical structure, this also causes the raw materials to be fed smoothly, resulting in relatively poor stability. Summary of the Invention

[0008] The purpose of the utility model is to provide a compound vibrating screen with high stability and compact structure for the above problems existing in the prior art.

[0009] The purpose of the utility model can be achieved by the following technical solutions:

[0010] A compound vibrating screen includes a frame. It is characterized in that it further includes a hopper, a screen hopper, a support assembly and a vibration assembly. The inside of the hopper is a cavity and both its upper and lower ends are open. The hopper is located above the frame. The upper end of the support assembly is fixedly connected to the hopper, and the lower end of the support assembly is fixedly connected to the frame. The inside of the screen hopper is a cavity and its upper part and one end are open. The screen hopper is connected to the frame through the vibration assembly. The lower end of the hopper is communicated with the upper part of the screen hopper.

[0011] This compound vibrating screen creatively arranges the hopper and the screening hopper in an overlapping connection up and down. Under the action of the hopper, the ore raw materials to be processed can smoothly enter the hopper.

[0012] Since the hopper is connected to the screening hopper, the ore raw materials finally enter the screening hopper stably.

[0013] Under the action of the vibration component, the screening hopper can vibrate stably and continuously. The ore raw materials in the screening hopper can be smoothly discharged from the opening at the end of the screening hopper under the action of vibration.

[0014] In addition, under the action of the support component, the hopper can be stably connected to the upper part of the frame.

[0015] In the above compound vibrating screen, the hopper includes a feeding part and a discharging part. The size of the upper port of the feeding part is larger than that of its lower port, and the upper and lower parts of the feeding part are smoothly transitioned. The discharging part is cylindrical, and the upper part of the discharging part is fixedly connected and communicated with the lower part of the feeding part. The upper end of the screening hopper is sleeved at the discharging part.

[0016] Since the feeding part is funnel-shaped, the raw materials can be stably and smoothly put into the hopper.

[0017] The discharging part is connected to the screening hopper, and at the same time, the discharging part is fixedly connected to the lower part of the feeding part. Therefore, finally, the ore raw materials can smoothly enter the screening hopper.

[0018] In the above compound vibrating screen, the support component includes a column and a connecting edge protruding laterally from the outside of the feeding part of the hopper. The lower end of the column is fixedly connected to the frame through a fastener. The upper end of the column has a connecting block in the shape of a block. There is a positioning notch on the connecting block that matches the connecting edge. The connecting block contacts and is fixedly connected to the outer side of the feeding part, and the connecting edge is embedded in the positioning notch.

[0019] The connecting edge and the positioning notch on the connecting block can form a pre-positioning connection. Finally, the connecting block and the hopper are fixedly connected by welding.

[0020] Since the positioning block contacts the side surface of the hopper, its connection stability is relatively high.

[0021] In the above compound vibrating screen, the number of the connecting edges is several. The several connecting edges are arranged adjacent to each other up and down on the outside of the feeding part. The connecting block has the same number of positioning notches as the connecting edges and they correspond to each other one by one.

[0022] The multiple connecting edges and the corresponding positioning notches on the connecting block can effectively improve the stability of the pre-positioning connection between the hopper and the column.

[0023] In the above compound vibrating screen, the connecting block and the column are of an integral structure.

[0024] This can appropriately improve its structural compactness.

[0025] In the above-mentioned compound vibrating screen, the number of the columns is four, two of which are connected to the front and rear parts on one side of the feeding part, and the other two columns are connected to the front and rear parts on the other side of the feeding part.

[0026] The arrangement of the four columns can stably connect the hopper to the frame.

[0027] In the above-mentioned compound vibrating screen, the vibration component includes a spring and an exciter. The bottom of the above-mentioned sieve hopper has inclined connecting plates I and II. The upper ends of the above-mentioned connecting plate I and the connecting plate II are respectively fixed at the front and rear positions of the bottom of the sieve hopper. The lower end of the above-mentioned connecting plate I is fixedly connected to the lower end of the connecting plate II. The above-mentioned exciter is fixedly connected to the connecting plate I. The two ends of the above-mentioned spring are respectively fixedly connected to the frame and the sieve hopper.

[0028] Both the connecting plate I and the connecting plate II are inclined. The connecting plate I provides enough positions for the exciter to be connected. The inclined exciter can achieve a better vibration effect.

[0029] The main function of the connecting plate II is to support and position the connecting plate I, ensuring that the connecting plate I is stably in the set inclined angle position.

[0030] In the above-mentioned compound vibrating screen, several adjacent springs form an elastic connection unit. The number of the elastic connection units is three. Two of the elastic connection units are arranged on both sides of the sieve hopper, and the other elastic connection unit is arranged at the end of the sieve hopper and this elastic connection unit is at the opposite end of the opening end of the sieve hopper.

[0031] The arrangement of the three elastic connection units not only stably connects the sieve hopper to the lower part of the hopper, but also enables the sieve hopper to vibrate stably under the action of the exciter.

[0032] In the above-mentioned compound vibrating screen, the feeding part of the hopper has a reinforcing rod, and the two ends of the reinforcing rod are respectively fixedly connected to both sides of the inner cavity of the feeding part.

[0033] The reinforcing rod can effectively improve the strength at the upper port of the hopper.

[0034] In the above-mentioned compound vibrating screen, a spring seat is fixedly connected to the outside of the sieve hopper, and the upper end of the above-mentioned spring is fixedly connected to the spring seat.

[0035] The spring seat provides enough positions for the spring to be connected.

[0036] Compared with the prior art, in this compound vibrating screen, since the hopper and the sieve hopper are centrally arranged, therefore, the ore raw materials can be smoothly fed into the sieve hopper, and its stability is relatively high.

[0037] Meanwhile, the support component utilizes the hopper's own funnel structure, increasing the contact area between the column and the hopper, ultimately ensuring the connection stability between the support component and the hopper, and further enhancing its stability.

[0038] In addition, the inclined vibrator is directly connected to the screening hopper. During the operation of the vibrator, the screening hopper can vibrate stably under the action of the elastic connection unit. Its structure has high application value. Brief Description of the Drawings
