Description

Technical Field

[0001] The utility model relates to the technical field of screening and processing, in particular to a double-layer vibrating screen for debris processing. Background Art

[0002] In the fields of industrial production, construction and material recycling, it is often necessary to process various types of debris to separate particles of different sizes or remove impurities. Traditional debris processing methods usually include manual screening or the use of simple screening tools. These methods are not only inefficient, but also labor-intensive and difficult to meet the needs of modern industrial production.

[0003] In order to improve the efficiency and quality of debris processing, a variety of automated or semi-automated debris processing equipment has appeared on the market, among which vibrating screen is a commonly used equipment. Vibrating screen uses vibration to sieve the material on the screen, thereby achieving separation of different particle sizes.

[0004] Especially in the process of screening impurities, how to control the synchronization of material feeding and screening has become an urgent problem to be solved. If the feeding speed is too fast, the material will stay on the screen too short, thus affecting the screening effect and making some impurities unable to be effectively separated; while if the feeding speed is too slow, the screening efficiency will be reduced and it will not meet the needs of large-scale production. Utility Model Content

[0005] The utility model aims at the technical problems existing in the prior art and provides a double-layer vibrating screen for processing debris to solve the problem that the synchronization between material feeding and screening of the vibrating screen is poor and thus affects the screening effect.

[0006] The utility model provides a technical solution to the above-mentioned technical problems as follows: a double-layer vibrating screen for debris processing, comprising a main frame, on which an upper loading box and a screening frame directly below the upper loading box are sequentially mounted; a feed opening is reserved at the top of the upper loading box, and a feed port is reserved at the bottom; an inclined discharge plate and a screen above the discharge plate are mounted on the screening frame; the main frame is also provided with a collecting bucket below the discharge plate.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, material-blocking protrusions are formed on the side edges around the screen.

[0009] Furthermore, a debris discharge opening is reserved along one side of the material blocking protrusion.

[0010] Furthermore, the main frame is also provided with a plurality of elastic support members for elastically supporting the screening frame.

[0011] Furthermore, the elastic support member includes a limit rod that is slidably matched with the screening frame, and a spring is disposed on the outer sleeve of the limit rod.

[0012] Furthermore, a vibration motor is installed on the screening frame.

[0013] Furthermore, a blocking plate capable of shielding the discharge opening is provided along the discharge opening of the upper material loading box, and limiting parts slidably matched with the blocking plate are formed on both sides of the discharge opening of the upper material loading box.

[0014] Furthermore, a handle is formed on the outer side of the blocking plate.

[0015] Furthermore, the inner diameter of the collecting bucket gradually narrows from top to bottom, and a discharge port is provided at the lowest point.

[0016] Moreover, the double-layer vibrating screen for debris processing provided by the utility model has at least the following beneficial effects compared with the prior art:

[0017] 1. By setting a blocking plate that can cover the discharge port, the user can control the material discharge speed by adjusting the position of the blocking plate according to actual production needs, thereby ensuring that the material stays on the screen for a moderate time, neither too fast nor too slow, thus ensuring the screening effect.

[0018] 2. The combination of the inclined feeding plate and the screen allows the material to form a continuous flow state during the screening process, effectively improving the screening efficiency. At the same time, the design of the material blocking protrusion prevents the material from overflowing from the edge of the screen, further ensuring the accuracy of the screening.

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0027] like Figure 1-Figure 4 As shown, the present utility model is designed 1. A double-layer vibrating screen for debris processing, characterized in that it includes a main frame 1, on which an upper loading box 2 and a screening frame 3 located directly below the upper loading box 2 are sequentially mounted; a feed opening is reserved at the top of the upper loading box 2, and a discharge opening is reserved at the bottom; an inclined discharge plate 3.1 and a screen 3.2 located above the discharge plate 3.1 are mounted on the screening frame 3; the main frame 1 is also provided with a collecting bucket 4 located below the discharge plate 3.1.

[0028] As an implementation mode, the sieve 3.2 is formed with material-blocking protrusions 3.3 on the sides thereof.

[0029] Specifically, a debris discharge opening 3.4 is reserved along one side of the material blocking protrusion 3.3.

[0030] As an implementation mode, the main frame body 1 is further provided with a plurality of elastic support members 5 for elastically supporting the screening frame 3 .

[0031] Specifically, the elastic support member 5 comprises a limit rod 5.1 which is slidably matched with the screening frame 3, and a spring 5.2 is disposed on the outer sleeve of the limit rod 5.1.

[0032] As an implementation mode, a vibration motor 6 is installed on the screening frame 3 .

[0033] As an implementation mode, a blocking plate 7 capable of shielding the discharge opening is provided along the discharge opening of the upper material loading box 2 , and limiting members 8 slidably matched with the blocking plate 7 are formed on both sides of the discharge opening of the upper material loading box 2 .

[0034] In addition, a handle 7.1 is formed on the outer side of the blocking plate 7.

[0035] As an implementation mode, the inner diameter of the collecting bucket 4 gradually narrows from top to bottom, and a discharge port is opened at the lowest point.

[0036] The working principle of the utility model is as follows:

[0037] 1 Material loading: The material to be screened is loaded through the feed opening at the top of the upper loading box 2, and the material is naturally accumulated in the upper loading box 2.

[0038] 2 Material feeding: The material feeding speed is controlled by adjusting the blocking plate 7 at the feeding opening of the upper material feeding box 2. The blocking plate 7 slides along the limiters 8 on both sides of the feeding opening of the upper material feeding box 2 to achieve the opening and closing adjustment of the feeding opening. The handle 7.1 is convenient for users to operate the blocking plate 7.

[0039] 3 Screening process: The material falls from the discharge port of the upper material box 2 onto the inclined discharge plate 3.1 of the screening frame 3, and then slides along the discharge plate 3.1 onto the screen 3.2. The material blocking protrusions 3.3 on the sides of the screen 3.2 prevent the material from overflowing from the edge of the screen. The vibration motor 6 drives the screening frame 3 to vibrate, so that the material is screened on the screen.

[0040] 4 Screening effect: The screen 3.2 separates the materials according to the particle size. The materials that meet the requirements fall into the collection bucket 4 through the screen, while the larger impurities are blocked on the screen. The impurity discharge port 3.4 reserved on one side of the material blocking protrusion 3.3 is convenient for cleaning the impurities on the screen.

[0041] 5 Collection and discharge: The inner diameter of the collection bucket 4 gradually narrows from top to bottom, which is convenient for collecting the screened materials. The discharge port at the lowest point of the collection bucket is convenient for discharging the materials.

[0042] Elastic support and vibration mechanism

[0043] The elastic support member 5 provided on the main frame 1 is slidably matched with the screening frame 3 through the limit rod 5.1, and the spring 5.2 provided outside the limit rod 5.1 provides elastic support for the screening frame 3. When the vibration motor 6 drives the screening frame 3 to vibrate, the elastic support member 5 can buffer the vibration impact, making the screening process more stable and efficient.
