Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically a vibrating screen with a rotating function. Background Technology

[0002] Vibrating screens typically utilize the principle of vibration motor excitation and operate by using the reciprocating rotary vibration generated by the vibrator. This causes the material to be thrown up on the screen surface and move forward in a straight line. With a properly matched screen, the screening purpose is achieved. The upper rotating weight of the vibrator causes the screen surface to produce planar rotary vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. The combined effect of these two factors results in a complex rotary vibration of the screen surface.

[0003] Application number CN202222498739.2 discloses a vibrating screen with a rotating function, including a shell, a shock-absorbing base at the bottom of the shell, a vibrating mechanism inside the shell, and a lifting protective cover inside the shell. The protective cover is connected to the shell via a telescopic element, and the vibrating mechanism is located inside the protective cover. A feed body is provided on the shell. The vibrating mechanism includes a vibrating screen plate, which is drivenly connected to a rotating element mounted on the shell. A vibrating motor is mounted on the vibrating screen plate. This utility model, employing the above-described structure, provides a vibrating screen with a rotating function, solving the problems of traditional vibrating screens lacking a rotating function and materials easily flying off the screen plate during screening.

[0004] During operation, this vibrating screen lacks a dedicated collection and discharge mechanism for the waste generated during screening, resulting in easy accumulation of waste, incomplete separation, and insufficient discharge power. Ultimately, this affects the screening efficiency and continuous operation capability of the equipment. If applied to screening scenarios with high impurity content, frequent shutdowns for cleaning may be required, limiting its practicality. Utility Model Content

[0005] The purpose of this invention is to provide a vibrating screen with a rotating function to solve the problem of efficient discharge of waste materials after screening.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a vibrating screen with a rotating function, comprising a fixed assembly and a vibrating screening assembly. The vibrating screening assembly is installed on the inner walls of the fixed assembly. The fixed assembly includes a housing, on which a rotary motor is fixedly installed at the bottom outer wall of the housing. One end of the shaft of the rotary motor extends upward to the bottom of the housing. A linkage rotating block is installed at the shaft end of the rotary motor. A linkage circular frame is fixedly connected to the outer walls of the linkage rotating block. The circular frame of the linkage circular frame is close to the bottom inner walls of the housing. A conical disc is provided at the top of the linkage rotating block. A concave rotating disk is fixedly installed on the outer walls of the conical disc. The outer diameter of the concave rotating disk has a certain gap with the housing. An annular limiting plate is fixedly installed on the inner walls of the housing between the linkage circular frame and the concave rotating disk. A drop groove is formed on the upper surface of the annular limiting plate. The purpose of this design is that during the operation of the vibrating screen, the material enters the shell from the feed inlet, the rotary motor starts, its shaft drives the linkage block to rotate, the linkage block drives the linkage circular frame to rotate, agitating the lighter waste material at the bottom of the shell, and moving it to the waste outlet through the drop groove on the annular limit plate. Simultaneously, the conical disc at the top of the rotating block rotates, causing the material to spread outwards. The vibrating motor vibrates the entire structure, and the material moves on the concave rotating disc. Material not considered waste continues to rise and is further screened by the screen plates on the inner walls around the top of the shell. Qualified material is discharged from the outlet. The rotating block drives the connecting circular frame to rotate, directly agitating the lighter waste material at the bottom of the shell. Combined with the design of the drop trough and waste outlet, the waste is discharged in a directional manner, preventing waste from accumulating at the bottom, ensuring a clean screening environment, and improving screening efficiency. The rotating motor drives the connecting circular frame and conical disc to rotate, realizing the dynamic distribution and initial separation of materials. The vibrating motor provides vibration, promoting the loosening and separation of material particles. The combination of the two forms a compound motion, which not only ensures the effective discharge of lighter waste material but also fully screens other materials, improving screening accuracy and quality.

[0008] Furthermore, a waste outlet is provided on the inner wall of one side of the bottom surface of the shell, and the discharge trough and waste outlet communicate with the concave turntable and the bottom cavity of the shell. The purpose of this arrangement is that during the operation of the vibrating screen, the waste outlet communicates with the discharge trough and the bottom cavity of the shell, providing a discharge channel for lighter waste materials agitated by the linked circular frame, ensuring that the waste materials flow out smoothly and avoiding accumulation inside the shell.

[0009] Furthermore, a sieve plate is fixedly installed on the inner wall around the top of the shell, and a discharge port is provided on one outer wall of the shell, which is located between the conical disc and the sieve plate. The purpose of this arrangement is that the sieve plate is fixed to the inner wall around the top of the shell to finely screen materials that are not considered waste. Materials that meet the requirements pass through the sieve plate and are discharged through the discharge port located between the conical disc and the sieve plate, thereby achieving material grading.

[0010] Furthermore, support rods are welded to the inner walls around the bottom of the housing, and a feed inlet is provided on the outer wall at the middle of the top of the housing. The purpose of this arrangement is that, during the operation of the vibrating screen, the support rods welded to the inner walls around the bottom of the housing provide stable support for the equipment; the feed inlet, located on the outer wall at the middle of the top of the housing, serves as a material input channel, allowing the material to smoothly enter the screening system.

[0011] Furthermore, a ring of spiral blades is fixedly installed on the inner wall around the feed inlet. The purpose of this arrangement is that, during the operation of the vibrating screen, the spiral blades on the inner wall around the feed inlet initially crush the material as it enters, reducing the particle size and making the material easier to separate during subsequent screening. It also facilitates the agitation and discharge of lighter waste materials by the linkage with the circular frame.

[0012] Furthermore, a vibrating motor is fixedly installed on the outer walls of both sides of the bottom surface of the housing. The purpose of this arrangement is that, during the operation of the vibrating screen, the vibrating motor is fixedly installed on the outer walls of both sides of the bottom surface of the housing, generates vibration during operation and transmits it to the entire housing and internal components (such as concave turntable, screen plate, etc.), assists in material screening, enhances the separation effect of lighter waste materials from other materials, and facilitates the linkage of the circular frame to agitate and discharge lighter waste materials.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model uses a rotary motor, a conical disc and a connecting circular frame to drive the connecting circular frame and the conical disc to rotate, thereby achieving dynamic distribution and initial separation of materials. The connecting circular frame is driven to rotate by the linkage block, which directly agitates the lighter waste material at the bottom of the shell. Combined with the design of the drop trough and waste port, the waste material is discharged in a directional manner, avoiding the accumulation of waste material at the bottom and ensuring a clean screening environment.

[0015] (2) This utility model, through the setting of a spiral blade assembly and a vibrating motor, uses a spiral blade assembly on the inner wall around the feed inlet to initially crush the material when it enters, reducing the particle size of the material and making it easier to separate the material in the subsequent screening process. It also facilitates the linkage of the circular frame to agitate and discharge lighter waste materials. The vibrating motor is fixedly installed on the outer walls of both sides of the bottom surface of the shell. When working, it generates vibration and transmits it to the entire shell and internal components (such as concave turntable, screen plate, etc.), assisting in the screening of materials, enhancing the separation effect of lighter waste materials from other materials, and facilitating the linkage of the circular frame to agitate and discharge lighter waste materials.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-4As shown, this utility model is a vibrating screen with a rotating function, including a fixed assembly 1 and a vibrating screening assembly 2. The vibrating screening assembly 2 is installed on the inner walls of the fixed assembly 1. The fixed assembly 1 includes a housing 101. A rotary motor 203 is fixedly installed on the outer wall of the bottom middle section of the housing 101. One end of the shaft of the rotary motor 203 extends upward to the bottom of the housing 101. A linkage rotating block 204 is installed on the shaft end of the rotary motor 203. A linkage is fixedly connected to the outer walls of the linkage rotating block 204. The circular frame 205 is closely attached to the inner walls of the bottom perimeter of the housing 101. A conical disc 206 is provided at the top of the rotating block 204. A concave disc 207 is fixedly installed on the outer walls of the conical disc 206. The outer diameter of the concave disc 207 has a certain gap with the housing 101. An annular limiting plate 209 is fixedly installed on the inner walls of the housing 101 between the rotating frame 205 and the concave disc 207. A drop groove 210 is provided on the upper surface of the annular limiting plate 209. The purpose of this arrangement is that during the operation of the vibrating screen, material enters the housing 101 through the feed inlet 103. The rotary motor 203 starts, and its shaft drives the rotating block 204 to rotate. The rotating block 204 drives the rotating frame 205 to rotate, agitating the lighter waste material at the bottom of the housing 101. The waste material then moves towards the waste outlet 105 through the drop groove 210 on the annular limiting plate 209 and is discharged. Simultaneously, the conical disc 206 at the top of the linkage rotating block 204 rotates, causing the material to spread outwards. The vibrating motor 201 works, causing the entire structure to vibrate. The material moves on the concave rotating disc 207. Material not considered waste continues to rise and is further screened by the sieve plate 208 on the inner wall of the top of the shell 101. Qualified material is discharged from the discharge port 104. The linkage rotating block 204 drives the linkage circular frame 205 to rotate, directly agitating the lighter waste material at the bottom of the shell 101. Combined with the design of the drop trough 210 and the waste port 105, the waste is discharged in a directional manner, avoiding the accumulation of waste at the bottom, ensuring a clean screening environment, and improving screening efficiency. The rotating motor drives the linkage circular frame 205 and the conical disc 206 to rotate, realizing the dynamic distribution and initial separation of the material. The vibrating motor 201 provides vibration, promoting the loosening and separation of material particles. The combination of the two forms a compound motion, which not only ensures the effective discharge of lighter waste material, but also fully screens other materials, improving screening accuracy and quality.

[0026] A waste outlet 105 is provided on the inner wall of one side of the bottom surface of the shell 101. The drop trough 210 and the waste outlet 105 communicate with the concave turntable 207 and the bottom cavity of the shell 101. The purpose of this arrangement is that during the operation of the vibrating screen, the waste outlet 105 communicates with the drop trough 210 and the bottom cavity of the shell 101, providing a discharge channel for the lighter waste material agitated by the linkage circular frame 205, ensuring that the waste material flows out smoothly and avoiding accumulation inside the shell.

[0027] A sieve plate 208 is fixedly installed on the inner wall around the top of the housing 101, and a discharge port 104 is provided on one outer wall of the housing 101, which is located between the conical disc 206 and the sieve plate 208. The purpose of this arrangement is that the sieve plate 208 is fixed to the inner wall around the top of the housing 101 to perform fine screening of materials that are not considered waste. Materials that meet the requirements pass through the sieve plate 208 and are discharged through the discharge port 104 located between the conical disc 206 and the sieve plate 208, thereby achieving material grading.

[0028] Support rods 102 are welded to the inner walls around the bottom of the housing 101, and a feed inlet 103 is provided on the outer wall at the middle of the top of the housing 101. The purpose of this arrangement is that, during the operation of the vibrating screen, the support rods 102 are welded to the inner walls around the bottom of the housing 101 to provide stable support for the equipment; the feed inlet 103 is located on the outer wall at the middle of the top of the housing 101, serving as a material input channel so that the material can smoothly enter the screening system.

[0029] A spiral blade assembly 202 is fixedly installed on the inner wall around the feed inlet 103. The purpose of this arrangement is that, during the operation of the vibrating screen, the spiral blade assembly 202 on the inner wall around the feed inlet 103 initially crushes the material when it enters, reducing the particle size of the material, making it easier to separate the material in the subsequent screening process, and also facilitating the linkage of the circular frame 205 to agitate and discharge lighter waste materials.

[0030] Vibration motors 201 are fixedly installed on the outer walls of both sides of the bottom surface of the housing 101. The purpose of this arrangement is that, during the operation of the vibrating screen, the vibration motors 201 are fixedly installed on the outer walls of both sides of the bottom surface of the housing 101, and generate vibrations during operation, which are transmitted to the entire housing 101 and internal components (such as the concave turntable 207, screen plate 208, etc.), to assist in material screening, enhance the separation effect of lighter waste materials from other materials, and facilitate the linkage of the circular frame 205 to agitate and discharge lighter waste materials.

[0031] In use, the material enters through the feed inlet 103 on the outer wall of the top middle section of the housing 101. The spiral blade assembly 202 on the inner wall of the feed inlet 103 performs initial crushing of the material. Subsequently, the rotary motor 203 starts, and its shaft drives the linkage rotating block 204 to rotate. The linkage rotating block 204 further drives the linkage circular frame 205, the conical disc 206, and the concave disc 207 to rotate synchronously. At the same time, the vibration motors 201 on both sides of the bottom surface of the housing 101 work, causing the entire device to vibrate.

[0032] Under the combined action of rotation and vibration, the lighter waste material is agitated by the linkage circular frame 205 and discharged outward through the waste port 105 on the inner wall of one side of the bottom surface of the shell 101 via the drop groove 210 on the annular limiting plate 209. The remaining material diffuses outward under the rotation of the conical disc 206, and after passing through the concave turntable 207, it reaches the sieve plate 208 on the inner wall of the top of the shell 101. The qualified material after fine screening by the sieve plate 208 is discharged from the discharge port 104 located between the conical disc 206 and the sieve plate 208. Throughout the process, the support rods 102 on the inner wall of the bottom of the shell 101 provide stable support for the device, ensuring the stable operation of each component.
