A multi-layer high-efficiency vibrating screening device

Abstract

This utility model discloses a multi-layer high-efficiency vibrating screening device, including a base, with several support columns arranged inside the base, and discharge hoppers welded between the support columns. In this utility model, by starting the vibrating motor at the bottom of the discharge hopper, the vibrating motor generates a linear vibration trajectory through excitation force. Since the discharge hopper is fixed between the support columns, and multiple screening hoppers with screen mesh sizes decreasing from top to bottom are stacked on top of the support columns, and the bottoms of the support columns are connected to the base through vibration isolation springs, as the vibrating motor continues to work, the linear vibration generated by the vibrating motor pushes the material in the multiple screening hoppers to move along the corresponding screen surface and complete the grading and screening. The vibration isolation springs are used to bear the entire weight of the vibrating screen box and ensure the stability of the vibration trajectory. The mounting blocks at the upper and lower ends of the connecting rods make the multiple screening hoppers detachable, facilitating later maintenance and replacement.

Description

Technical Field

[0001] This utility model relates to the field of building material processing technology, and in particular to a multi-layer high-efficiency vibrating screening device. Background Technology

[0002] Perlite is a glassy rock formed from acidic lava from volcanic eruptions through rapid cooling. It is a valuable non-metallic mineral with outstanding high-temperature expansion properties. Perlite is a lightweight, porous material with excellent insulation properties and a wide range of applications, including various industrial and horticultural uses. It is a commonly used building insulation material in the construction industry, frequently used for exterior wall insulation. However, perlite is highly absorbent and prone to water penetration and weight gain. Therefore, when used for exterior wall insulation, a waterproof coating is usually applied to the outer layer. Furthermore, when using perlite as a building insulation material, it is necessary to use a screening device to separate the particle size of the material.

[0003] It is known that screening involves manually shoveling building materials onto a screen for sieving. However, manual screening is not only physically demanding but also inefficient. Since building materials have different particle sizes, a single-size screen is not effective enough. Smaller screens are needed to screen larger particles in sand again, requiring multiple screening operations. This greatly increases the workload of workers and reduces the efficiency of building material screening.

[0004] To address this issue, a multi-layer high-efficiency vibrating screening device is proposed, which has the advantages of multi-layer screening and convenient screen bucket replacement and maintenance, thereby solving the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-layer high-efficiency vibrating screening device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-layer high-efficiency vibrating screening device, comprising a base, a plurality of support columns arranged on the inner side of the base, and discharge hoppers welded between the support columns. Multiple screening hoppers are stacked above the discharge hoppers, and screens are installed at the bottom of each screening hopper. A connecting rod is installed between adjacent screening hoppers. A vibrating motor is fixedly installed at the bottom of the discharge hopper by bolts. Mounting blocks that connect to the sides of the screening hoppers are provided at the upper and lower ends of the connecting rods, and the surfaces of the mounting blocks are connected to the screening hoppers by quick-release screws. The tops of the support columns are connected to the lowest screening hopper by bolts, and vibration isolation springs connected to the inner side of the base are fixed at the bottom of each support column. A discharge nozzle is installed at the right end of each screening hopper, and a support is welded to the side of each screening hopper with the discharge nozzle. An inclined platform is welded to the bottom of the base.

[0007] As a further description of the above technical solution: an electric push rod is fixedly installed at the bottom of the support, and a baffle is fixedly installed at the bottom of the electric push rod. A rectangular opening is opened on the top surface of the discharge nozzle corresponding to the baffle, and the baffle extends through the rectangular opening to the inside of the discharge nozzle.

[0008] As a further description of the above technical solution: the inner side of the screening hopper has an octagonal structure with two guide plates installed, and the two guide plates are set towards the discharge nozzle of the screening hopper.

[0009] As a further description of the above technical solution: the screen aperture of the multiple screening hoppers decreases sequentially from top to bottom, and the top surface of the multiple screening hoppers is provided with an opening, and the bottom surface of the multiple screening hoppers is welded with a rectangular guide frame corresponding to the screen.

[0010] As a further description of the above technical solution: the mounting block of the connecting rod has two through holes on its surface, and the connecting rod as a whole has a square steel tube structure.

[0011] As a further description of the above technical solution: the base, discharge hopper, and multiple screening hoppers are arranged from bottom to top on the slope surface of the inclined platform.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, by starting the vibrating motor at the bottom of the discharge hopper, the vibrating motor generates a linear vibration trajectory through excitation force. Since the discharge hopper is fixed between several support columns, and multiple screening hoppers with screen mesh sizes decreasing from top to bottom are stacked on top of the support columns, and the bottoms of the support columns are connected to the base through vibration isolation springs, as the vibrating motor continues to work, the linear vibration generated by the vibrating motor pushes the material in the multiple screening hoppers to move along the corresponding screen surface and complete the grading and screening. The vibration isolation springs are used to bear the entire weight of the vibrating screen box and ensure the stability of the vibration trajectory. The mounting blocks at the upper and lower ends of the connecting rod make the multiple screening hoppers detachable, which is easy for later maintenance and replacement.

[0014] In this invention, by activating the electric push rod installed on the support, the electric push rod drives the baffle fixedly installed at its bottom to rise and fall, allowing the baffle to flexibly switch between inserting into and disengaging from the discharge nozzle. When the baffle is inserted into the discharge nozzle, the discharge nozzle of the screening hopper is in a sealed state, facilitating the screening of perlite particles. When the baffle is disengaged from the discharge nozzle, the discharge nozzle of the screening hopper is in an open state. Combined with the vibration of the vibrating motor and the inclined platform installed at the bottom of the base, the discharge hopper and multiple screening hoppers are tilted, facilitating full discharge.

[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.

[0022] According to an embodiment of the present invention, a multi-layer high-efficiency vibrating screening device is provided.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a multi-layer high-efficiency vibrating screening device according to an embodiment of the present invention includes a base 1, a plurality of support columns 6 arranged on the inner side of the base 1, and a discharge hopper 7 welded between the plurality of support columns 6. A plurality of screening hoppers 3 are stacked above the discharge hoppers 7, and a screen 10 is installed at the bottom of each screening hopper 3. A connecting rod 5 is installed between two adjacent screening hoppers 3. A vibrating motor 8 is fixedly installed at the bottom of the discharge hopper 7 by bolts. Mounting blocks 12 are provided at the upper and lower ends of the connecting rod 5, which are connected to the side of the screening hopper 3. The surface of the mounting block 12 is connected to the screening hopper 3 by quick-release screws. The tops of the plurality of support columns 6 are connected by... Bolts are connected to the bottommost screening hopper 3, and vibration isolation springs 9 connected to the inner side of the base 1 are fixed to the bottom of several support columns 6. A discharge nozzle 4 is installed at the right end of each screening hopper 3, and a support 14 is welded to the side of each screening hopper 3 with the discharge nozzle 4. An inclined platform 2 is welded to the bottom of the base 1. The vibration motor 8 and the electric push rod 15 are controlled by manually starting and stopping the switch. The wiring diagram of the power components and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring arrangement will not be explained in detail in this utility model.

[0024] In one embodiment, an electric push rod 15 is fixedly installed at the bottom of the support 14, and a baffle 16 is fixedly installed at the bottom of the electric push rod 15. A rectangular opening is provided on the top surface of the discharge nozzle 4 corresponding to the baffle 16. The baffle 16 extends through the rectangular opening to the inside of the discharge nozzle 4. With this structure, by starting the electric push rod 15 installed on the support 14, the electric push rod 15 drives the baffle 16 fixedly installed at its bottom to rise / fall, so that the baffle 16 can flexibly switch between inserting into the discharge nozzle 4 and disengaging from the discharge nozzle 4. When the baffle 16 is inserted into the inside of the discharge nozzle 4, the discharge nozzle 4 of the screening hopper 3 is in a sealed state, which is convenient for screening perlite particles. When the baffle 16 is disengaged from the discharge nozzle 4, the discharge nozzle 4 of the screening hopper 3 is in an open state, which is convenient for the synchronous or single discharge of multiple screening hoppers 3.

[0025] In one embodiment, the inner side of the screening hopper 3 is equipped with two guide plates 13 in an octagonal structure, and the two guide plates 13 are set towards the discharge nozzle 4 of the screening hopper 3. This structure facilitates the guidance of perlite particles and makes discharge convenient.

[0026] In one embodiment, the mesh size of the screens 10 in the multiple screening hoppers 3 decreases from top to bottom, and the top surfaces of the multiple screening hoppers 3 are all open, and the bottom surfaces of the multiple screening hoppers 3 are all welded with rectangular guide frames 11 corresponding to the screens 10. With this structure, it is easy to screen perlite of different particle sizes, and the guide frames 11 are easy to guide the falling perlite.

[0027] In one embodiment, the mounting block 12 of the connecting rod 5 has two through holes on its surface, and the connecting rod 5 is a square steel pipe structure. This structure provides support between multiple screening hoppers 3 and makes the screening hoppers 3 detachable, which is convenient for later replacement and maintenance.

[0028] In one embodiment, the base 1, the discharge hopper 7, and the multiple screening hoppers 3 are arranged from bottom to top on the slope of the inclined platform 2. This structure allows the discharge hopper 7 and the multiple screening hoppers 3 to be arranged at an incline, which facilitates full material discharge.

[0029] Working principle:

[0030] In use, the perlite particles to be screened are first fed into the uppermost screening hopper 3. The vibrating motor 8 at the bottom of the discharge hopper 7 is then activated, causing it to generate a linear vibration trajectory through excitation force. Since the discharge hopper 7 is fixed between several support columns 6, and multiple screening hoppers 3 with screen mesh 10 apertures decreasing in size from top to bottom are stacked above the support columns 6, and the bottoms of the support columns 6 are connected to the base 1 via vibration isolation springs 9, the linear vibration generated by the vibrating motor 8, as it continues to operate, pushes the material in the multiple screening hoppers 3 along the corresponding screen surfaces to complete the grading and screening. The vibration isolation springs 9 are used to support the vibration of the screen. The entire weight of the screen box is controlled, and the vibration trajectory is kept stable. At the same time, the electric push rod 15 installed on the support 14 is activated, which causes the electric push rod 15 to drive the baffle 16 fixed at its bottom to rise / fall. This allows the baffle 16 to flexibly switch between inserting into the discharge nozzle 4 and disengaging from the discharge nozzle 4. When the baffle 16 is inserted into the discharge nozzle 4, the discharge nozzle 4 of the screening hopper 3 is in a sealed state, which facilitates the screening of perlite particles. When the baffle 16 is disengaged from the discharge nozzle 4, the discharge nozzle 4 of the screening hopper 3 is in an open state. Combined with the vibration of the vibrating motor 8 and the inclined platform 2 installed at the bottom of the base 1, the discharge hopper 7 and multiple screening hoppers 3 are tilted, which facilitates full discharge.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
