Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically to a multi-layer tiltable environmentally friendly vibrating screen. Background Technology

[0002] A screening machine is a vibrating screening machine that uses the relative motion between granular materials and the screen surface to allow some particles to pass through the screen holes, separating materials such as sand, gravel, and crushed stone into different grades according to particle size.

[0003] Existing multi-layer vibrating screens achieve multi-stage screening of materials by setting up multiple screens of different specifications and cooperating with a vibrator. In this method, dust adhering to the surface of the material is dispersed into the screening box due to vibration. This dust will overflow into the air through the feeding hopper or discharge chamber, affecting the air quality in the workshop and resulting in a high dust concentration around the device. On the other hand, it has low environmental protection performance and affects its performance. Therefore, there is an urgent need for a multi-layer tiltable environmentally friendly vibrating screen to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved In view of the shortcomings of the prior art, this application provides a multi-layer tiltable environmentally friendly vibrating screen, which solves the problems mentioned in the background art.

[0005] (II) Technical Solution This utility model is achieved through the following technical solution: This utility model proposes a multi-layer tiltable environmentally friendly vibrating screen, including a screening box. A dust removal component is fixed on the back wall of the screening box. The dust removal component includes a dust suction hood arrayed on the back wall of the screening box. One end of the dust suction hood is connected to a T-shaped extraction pipe. A T-shaped dust removal pipe is provided on one side of the extraction pipe. One end of the dust removal pipe is connected to a dust collector. Two sets of filter elements are symmetrically installed between the extraction pipe and the dust removal pipe. Two sets of valves are symmetrically arranged on both the extraction pipe and the dust removal pipe. A valve stem extends from the valve. One end of the valve stem is connected to a drive component. The drive component includes a drive box located at the upper end of the valve stem. A drive wheel is installed on one side of the drive box, and a driven wheel is installed on the other side of the drive box. A servo motor is also connected to the drive wheel.

[0006] By adopting the above technical solution, during the screening process, the dust collector in the dust removal assembly extracts the dust diffused in the screening box through the dust removal pipe, a set of filter elements, the extraction pipe, and the dust suction hood, and collects and filters it through the filter elements, thereby preventing dust from spreading in the workshop and improving its environmental friendliness. At the same time, during the filtration process, when the filter elements are severely clogged, the two sets of servo motors drive their respective drive wheels to rotate. The two sets of drive wheels then drive their respective driven wheels to rotate through the synchronous belt, and both of them drive the valve stem to rotate. The severely clogged channel of the filter element can be closed through a set of valves, and another set of new filter elements can be put into use. Thus, the other set of filter elements can be replaced while one set of filter elements is in use. The two sets of filter elements are used alternately to ensure continuous and efficient dust removal.

[0007] Furthermore, the filter element is threaded between the extraction pipe and the dust removal pipe, the valve is threaded onto the dust removal pipe and the extraction pipe, and the valve stem is rotatably mounted on the valve.

[0008] By adopting the above technical solution, the state of the valve can be changed by the valve stem, thereby realizing the conversion of the gas flow channel, and thus enabling the two sets of filter elements to be used alternately to filter and collect dust.

[0009] Furthermore, the outer sides of the driving wheel and the driven wheel are meshed with a synchronous belt, and the output shaft of the servo motor is fixedly connected to the driving wheel.

[0010] By adopting the above technical solution, the servo motor drives the drive wheel to rotate, and the drive wheel drives the driven wheel to rotate through the synchronous belt.

[0011] Furthermore, the driving wheel and the driven wheel are both fixedly connected to the top of the valve stem, the valve stem is connected to the bottom wall of the drive box via a bearing, and the drive box is fixed to the valve via a bracket.

[0012] By adopting the above technical solution, the driving wheel and the driven wheel respectively drive the valve stem to rotate, thereby realizing the synchronous opening and closing of the valve.

[0013] Furthermore, a screening assembly is installed inside the screening box, the screening assembly including a vibrator fixed to one side wall of the screening box, and a first screen is installed inside the screening box.

[0014] By adopting the above technical solution, the vibrator can enable the material to be vibrated and screened, and the first screen can perform primary screening of the material.

[0015] Furthermore, a second screen is installed below the first screen, and a guide plate is provided below the second screen. The first screen, the second screen, and the guide plate are all inclined.

[0016] By adopting the above technical solution, the second screen can perform secondary screening of the material, and the material after secondary screening is discharged and collected through the guide plate.

[0017] Furthermore, a feeding hopper is provided on one side of the upper end of the screening box, and a screen box is provided at the lowest point of both the first screen and the second screen, and a discharge cavity is opened therein. A baffle is installed in the discharge cavity through a slot.

[0018] By adopting the above technical solution, the material is injected into the screening box through the feeding hopper for screening. After screening is completed, the baffle is removed so that the screened material can be discharged and collected.

[0019] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: This invention utilizes a combination of a dust removal component and a drive component. During the screening process, the dust collector within the dust removal component extracts dust from the screening box and collects it through a filter element, thereby preventing dust from spreading throughout the workshop and improving environmental friendliness. Simultaneously, during the filtration process, when the filter element becomes severely clogged, a servo motor drives the drive wheel to rotate, which in turn drives the driven wheel to rotate via a synchronous belt. Both of these drives the valve stem to rotate synchronously, achieving a switch in the gas flow channel. This allows for the replacement of one set of filter elements while another set is in use. The alternating use of the two sets of filter elements ensures continuous and efficient dust removal with excellent performance. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the multi-layer tiltable environmentally friendly vibrating screen in this embodiment includes a screening box 1. A dust removal assembly 5 is fixed on the back wall of the screening box 1. The dust removal assembly 5 includes a dust collection hood 507 arrayed on the back wall of the screening box 1. One end of the dust collection hood 507 is connected to a T-shaped extraction pipe 503. A T-shaped dust removal pipe 502 is provided on one side of the extraction pipe 503. One end of the dust removal pipe 502 is connected to a dust collector 501. The extraction pipe 503 and the dust removal pipe 502 are symmetrical. Two sets of filter elements 504 are installed. Two sets of valves 505 are symmetrically arranged on both the extraction pipe 503 and the dust collection pipe 502. A valve stem 506 extends from each valve 505. One end of the valve stem 506 is connected to a drive assembly 6. The drive assembly 6 includes a drive housing 601 located at the upper end of the valve stem 506. A drive wheel 603 is installed on one side of the drive housing 601, and a driven wheel 605 is installed on the other side of the drive housing 601. Belts are fitted onto the drive wheel 603 and the driven wheel 605. A servo motor 602 is also connected to the drive wheel 603. During the screening process, the dust collector 501 in the dust removal assembly 5 sucks up the dust diffused in the screening box 1 through the dust removal pipe 502, a set of filter elements 504, the extraction pipe 503, and the dust suction hood 507, and collects and filters it through the filter element 504, thereby preventing dust from spreading in the workshop and improving its environmental protection. At the same time, during the filtration process, when the filter element 504 is severely clogged, the two sets of servo motors 602 drive their respective drive wheels 603 to rotate. The two sets of drive wheels 603 then drive their respective driven wheels 605 to rotate through the synchronous belt 604. Both of them then drive the valve stem 506 to rotate. The severely clogged channel of the filter element 504 can be closed through a set of valves 505, and another set of new filter elements 504 can be put into use. Thus, when one set of filter elements 504 is in use, the other set of filter elements 504 can be replaced. The two sets of filter elements 504 are used alternately to ensure continuous and efficient dust removal.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the filter element 504 is threaded between the extraction pipe 503 and the dust collection pipe 502. The valve 505 is threaded onto both the dust collection pipe 502 and the extraction pipe 503. The valve stem 506 is rotatably mounted on the valve. The synchronous belt 604 meshes with both the drive wheel 603 and the driven wheel 605. The output shaft of the servo motor 602 is fixedly connected to the drive wheel 603. Both the drive wheel 603 and the driven wheel 605 are fixedly connected to the top of the valve stem 506. The valve stem 506 is connected to the bottom wall of the drive box 601 via a bearing. The drive box 601 is fixed to the valve 505 via a bracket. During the dust removal process, the valve 505 allows the filter element to be threaded between the extraction pipe 503 and the dust collection pipe 502. When a set of filter elements 504 is put into use, the dust collector 501 extracts the dust generated during the screening process through the dust collection pipe 502, the put-in filter element 504, the extraction pipe 503, and the dust collection hood 507, and filters it through the filter element 504. When the filter element 504 is severely clogged, the servo motor 602 drives the drive wheel 603 to rotate, and the drive wheel 603 drives the driven wheel 605 to rotate through the synchronous belt 604. Both of them drive the valve stem 506 to rotate synchronously, realizing the conversion of the gas flow channel. Thus, when one set of filter elements 504 is in use, the other set of filter elements 504 can be replaced. The two sets of filter elements 504 are used alternately to ensure continuous and efficient dust removal.

[0025] like Figure 1 and Figure 3 As shown, in this embodiment, a screening assembly 4 is installed inside the screening box 1. The screening assembly 4 includes a vibrator 401 fixed to one side wall of the screening box 1. A first screen 402 is installed inside the screening box 1, and a second screen 403 is installed below the first screen 402. A guide plate 404 is provided below the second screen 403. The first screen 402, the second screen 403, and the guide plate 404 are all inclined. A feeding hopper 2 is provided on one side of the upper end of the screening box 1. The screen box is located at the first screen 402. The lowest point of the second screen 403 is provided with a discharge chamber. A baffle 3 is installed in the discharge chamber through a slot. During use, the material is injected into the screening box 1 through the feeding hopper 2. At this time, the vibrator 401 can make the material vibrate and screen. The first screen 402 can perform primary screening of the material, and the second screen 403 can perform secondary screening of the material. The material after secondary screening is discharged and collected through the guide plate 404. After screening is completed, the baffle 3 can be removed to discharge and collect the screened material.

[0026] The specific implementation process of this embodiment is as follows: First, place the device in position and connect the external power supply. During use, the material is injected into the screening box 1 through the feeding hopper 2. At this time, the vibrator 401 can make the material vibrate and screen. The first screen 402 can perform primary screening of the material, and the second screen 403 can perform secondary screening of the material. The material after secondary screening is discharged and collected through the guide plate 404. During the screening process, under the action of the valve 505, a set of filter elements 504 can be put into use. At this time, the dust collector 501 extracts the dust generated during the screening process through the dust collection pipe 502, the put-in filter elements 504, the extraction pipe 503, and the dust suction hood 507. The gas is filtered through filter element 504. When filter element 504 becomes severely clogged, servo motor 602 drives drive wheel 603 to rotate. Drive wheel 603 then drives driven wheel 605 to rotate via synchronous belt 604. Both of these drives valve stem 506 to rotate synchronously, thus switching the gas flow channel and putting a new filter element 504 into use. This allows for the replacement of one set of filter elements 504 while another set is in use. Alternating use of the two sets of filter elements 504 ensures continuous and efficient dust removal, preventing dust from spreading in the workshop and improving the environmental performance of the device. After screening is complete, baffle 3 can be removed to discharge and collect the screened material.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
