Description

Technical Field

[0001] This utility model relates to the technical field of material vibrating screening equipment, specifically to a vibration screen noise reduction device. Background Technology

[0002] A vibrating screen is a primary solids control device used for separating coarse and fine particles in a mud circulation system, and it is a very important piece of equipment in the mud circulation system. In a mud solids control system, the vibrating screen is generally installed on the mud tank to separate the drilling fluid into coarse and fine particles before it is transported to subsequent solids control equipment for further processing.

[0003] Currently, there are two main methods for installing vibrating screens on mud tanks: The first is to place the vibrating screen directly on the mud tank and then use angle irons to limit its position at the four corners; the second is to fix the vibrating screen by welding stop blocks. These stop blocks are divided into upper and lower parts: the upper part is welded to the vibrating screen base, and the lower part is welded to the main beam of the tank body, after which tension bolts are installed. Both methods involve placing the vibrating screen directly on the mud tank, meaning the vibrating screen base is in direct contact with the top of the tank. This rigid installation method generates significant noise during operation and fails to meet environmental protection requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a noise reduction device for a vibrating screen. Through the combined action of the shock-absorbing rubber pad, the steel limiting plate and the stud, the base of the vibrating screen makes soft contact with the top of the tank. During the operation of the vibrating screen, the shock-absorbing rubber pad is not easy to shift, which greatly reduces the noise on site. In addition, by connecting the stud with the mounting holes on the bottom surface of the side beam of the vibrating screen base at different positions, it can be adapted to mud tanks of various sizes. The structure is simple and the performance is stable.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vibration screen noise reduction device, comprising a shock-absorbing rubber pad, a steel limiting plate and a stud, wherein the shock-absorbing rubber pad and the steel limiting plate are integrally vulcanized, and one end of the stud is vertically connected to the steel limiting plate, and the other end extends toward the side beam of the vibrating screen base. The bottom surface of the side beam of the vibrating screen base is provided with several evenly distributed mounting holes that match the studs along the longitudinal direction of the vibrating screen.

[0006] As an improvement of this utility model, one side of the shock-absorbing rubber pad is connected to the side beam of the vibrating screen base by a stud, and the other side abuts against the upper surface of the main beam of the mud tank.

[0007] As an improvement of this utility model, the steel limiting plate is set inside the shock-absorbing rubber pad, and is located close to the side of the shock-absorbing rubber pad on the side beam of the vibrating screen base.

[0008] As an improvement of this utility model, the thickness of the shock-absorbing rubber pad is 20mm to 30mm.

[0009] As an improvement of this utility model, the steel limiting plate is provided with a number of regularly distributed sulfidation holes.

[0010] As an improvement of this utility model, the number of studs is at least two, and their positions are distributed along the longitudinal center of the steel limiting plate.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a noise reduction device for a vibrating screen, which, through the combined action of shock-absorbing rubber pads, steel limiting plates, and studs, makes soft contact between the vibrating screen base and the top of the tank, greatly reducing on-site noise; since the entire device is connected to the side beam of the vibrating screen base through mounting holes on the bottom surface of the side beam of the vibrating screen base via studs, the shock-absorbing rubber pads are not prone to displacement during the operation of the vibrating screen; by connecting the studs to mounting holes on the bottom surface of the side beam of the vibrating screen base at different positions, it can be adapted to mud tanks of various sizes, expanding the application range of the device, with a simple structure and stable performance.

[0012] Furthermore, one side of the shock-absorbing rubber pad is connected to the side beam of the vibrating screen base via studs, while the other side abuts against the upper surface of the main beam of the mud tank. By rotating the shock-absorbing rubber pad onto the main beam of the mud tank, structural stability is further increased.

[0013] Furthermore, the steel limiting plate is installed inside the damping pad, positioned close to the damping pad side of the vibrating screen base side beam. By placing the steel limiting plate inside the damping pad, the overall structure becomes more robust; positioning the steel limiting plate close to the damping pad side of the vibrating screen base side beam allows the damping pad to exert a greater damping effect, reducing the impact of the steel limiting plate on the damping pad.

[0014] Furthermore, the thickness of the shock-absorbing pads is 20mm to 30mm. Too thick a pad wastes material, while too thin one cannot compensate for flatness errors on the tank surface. The above range allows for material savings while potentially compensating for flatness errors on the tank surface, further enhancing the overall structural stability.

[0015] Furthermore, the steel limiting plate has several regularly distributed vulcanization holes. The vulcanization holes make the steel limiting plate and the shock-absorbing pad more firmly bonded.

[0016] Furthermore, the number of studs is at least two, and their positions are distributed along the longitudinal center of the steel limiting plate. This design further increases the overall structural stability of the device. Attached Figure Description

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] It should be noted that the terms "up," "down," "left," and "right" used in the embodiments of this utility model are only relative concepts or are based on the normal use of the product, and should not be considered as restrictive. Example 1

[0021] like Figures 1 to 4 As shown, a noise reduction device for a vibrating screen includes a shock-absorbing rubber pad 1, a steel limiting plate 2, and a stud 3. The shock-absorbing rubber pad 1 and the steel limiting plate 2 are integrally vulcanized. One end of the stud 3 is vertically connected to the steel limiting plate 2, and the other end extends towards the side beam 4 of the vibrating screen base. Preferably, the steel limiting plate 2 is disposed inside the shock-absorbing rubber pad 1, close to the side of the shock-absorbing rubber pad 1 on the side beam 4 of the vibrating screen base. Figure 2In this design, the steel limiting plate 2 is positioned near the lower side of the shock-absorbing pad 1. By placing the steel limiting plate 2 inside the shock-absorbing pad 1, the overall structure becomes more robust. Positioning the steel limiting plate 2 near the side beam 4 of the vibrating screen base allows the shock-absorbing pad 1 to exert a greater shock-absorbing effect, reducing the impact of the steel limiting plate 2 on the shock-absorbing pad 1. The bottom surface of the side beam 4 of the vibrating screen base 5 has several evenly distributed mounting holes 41 that match the studs 3. Preferably, the studs 3 are welded to the steel limiting plate 2. More preferably, the steel limiting plate 2 has connecting holes 22 that match the studs, allowing the studs 3 to be more securely fixed to the steel limiting plate 2. The shock-absorbing pad 1 is installed on the base of the vibrating screen 5 by passing the studs 3 through the mounting holes 41 and then using a lock nut. This design is simple in structure and easy to manufacture. One side of the shock-absorbing rubber pad 1 is connected to the side beam 4 of the vibrating screen base via studs 3, and the other side abuts against the upper surface of the main beam 71 of the mud tank 7.

[0022] Preferably, the thickness of the shock-absorbing pad 1 is 20mm to 30mm. If the shock-absorbing pad 1 is too thick, it wastes material; if it is too thin, it cannot compensate for the flatness error of the tank surface. By using the above-mentioned range, material can be saved while also compensating for the flatness error of the tank surface, further enhancing the stability of the overall structure.

[0023] Preferably, the steel limiting plate 2 has a plurality of regularly distributed vulcanization holes 21. The vulcanization holes 21 make the steel limiting plate 2 and the shock-absorbing pad 1 more firmly bonded.

[0024] Preferably, there are at least two studs 3, positioned along the longitudinal center of the steel limiting plate 3. In this embodiment, there are two studs 3.

[0025] like Figure 4 As shown, the vibrating screen 5 is installed on the main beam 71 of the mud tank 7 via a noise reduction device. The mud tank is 2500mm long, and there are floating platforms 6 on the left and right sides of the top of the tank for operators to walk on. By connecting the mounting holes 41 at different positions on the base longitudinal beam 4 with the studs 3, the shock-absorbing pads 1 can be installed on mud tanks 7 of different sizes. The structure is simple, easy to manufacture, and low in cost. Example 2

[0026] like Figure 5 As shown, the difference between this embodiment and embodiment one is that the length of the mud tank is 3000mm. By adjusting the position of the stud 3 and the mounting hole 41, the vibrating screen 5 can be conveniently installed on the main beam 71 of the tank body through the noise reduction device.

[0027] In summary, by changing the installation positions of the stud 3 and the mounting hole 41, this utility model allows the vibrating screen 5 to be installed on a mud tank 7 of any size, thereby achieving excellent noise reduction and expanding the application range of the product.

The above embodiments are only used to help understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
