Description

Technical Field

[0001] This application relates to the field of dewatering screen technology, and in particular to dewatering screens for mineral processing. Background Technology

[0002] Dewatering screens (also known as dewatering vibrating screens) are solid-liquid separation equipment widely used in industries such as coal, mining, sand and gravel, and building materials. They are mainly used for dewatering, demediuming, and desliming of materials such as mud, fine sand, and mineral slurry.

[0003] Currently, during the process of material falling from the feed port onto the screen surface, due to the effect of gravity acceleration, the ore will impact the screen surface with high speed and kinetic energy, especially concentrated at one end of the feed side. The high-intensity impact load will cause a certain area of ​​the screen to bear mechanical stress exceeding the design range for a long time, resulting in deformation or breakage of the screen, which will lead to problems such as enlarged screen mesh and reduced screening accuracy, ultimately affecting dewatering efficiency. Therefore, a dewatering screen for mineral processing was designed to solve the above-mentioned problems. Utility Model Content

[0004] To address this issue, this application provides a dewatering screen for mineral processing.

[0005] The dewatering screen for mineral processing provided in this application adopts the following technical solution:

[0006] A dewatering screen for mineral processing includes a bottom support. Support blocks are fixedly connected to the front, rear and sides of the upper end of the bottom support. A spring is fixedly installed on the upper end of the support block. A dewatering screen frame is fixedly installed on the upper end of the spring. An installation plate is slidably installed on one side of the feed section of the dewatering screen frame. A buffer component for buffering the discharge of mineral sand is installed on one side of the installation plate.

[0007] The buffer assembly includes a buffer plate, which is installed on one side of the mounting plate and is used to buffer the feeding of ore.

[0008] Preferably, the buffer plate is inclined, and a buffer block is provided on one side of the buffer plate.

[0009] Preferably, the buffer assembly further includes a mounting block, one side of which is fixedly connected to the sidewall of the mounting plate, the side of which is slidably connected to the mounting frame away from the mounting plate, one side of which is fixedly connected to a support plate, and one side of which is fixedly connected to the sidewall of the buffer plate.

[0010] Preferably, an elastic sheet is fixedly connected inside the mounting frame, and one side of the elastic sheet is fixedly connected to the side wall of the mounting block.

[0012] Preferably, the output end of the electric push rod is fixedly connected to one side of the mounting plate, and the electric push rod is fixedly installed on the upper end of the protective frame.

[0013] Preferably, the protective frame is fixedly connected to the front and rear parts by a fixing block, and the fixing block is fixedly installed on one side of the support block.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] In this invention, by using a buffer plate, mounting frame, elastic sheet, and mounting block at the slurry feeding point, the potential energy of the slurry impact can be converted into the elastic potential energy of the elastic sheet, thereby absorbing part of the gravitational potential energy of the slurry. This prevents the screen from deforming or breaking under stress when the slurry comes into contact with the screen. Furthermore, the position of the buffer plate can be adjusted by using an electric push rod, changing the contact position between the slurry and the screen at regular intervals. This prevents continuous impact on one part of the screen and avoids high-intensity impact loads causing a certain area of ​​the screen to bear mechanical stress exceeding the design range for a long time, which could lead to deformation or breakage of the screen.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a dewatering screen for mineral processing. (See also...) Figure 1-5A dewatering screen for mineral processing includes a bottom support 1. Support blocks 2 are fixedly connected to the front, rear and sides of the upper end of the bottom support 1. A spring 21 is fixedly installed on the upper end of the support block 2. A dewatering screen frame 3 is fixedly installed on the upper end of the spring 21. A vibrating motor 31 is installed on the upper end of the dewatering screen frame 3. A screen 33 is installed inside the dewatering screen frame 3. A discharge plate 32 is fixedly connected to one side of the screen 33. The screen 33, the discharge plate 32, the dewatering screen frame 3 and the vibrating motor 31 constitute the whole dewatering screen.

[0024] A mounting plate 4 is slidably installed on one side of the feed section of the dewatering screen frame 3. A buffer assembly for buffering the discharge of ore sand is installed on one side of the mounting plate 4. The buffer assembly includes a buffer plate 7, which is installed on one side of the mounting plate 4 for buffering the discharge of ore sand.

[0025] like Figure 4 As shown, the buffer plate 7 is inclined, and a buffer block 71 is provided on one side of the buffer plate 7 to improve the buffering effect of the buffer plate 7, so that the slurry falls more slowly after contacting the buffer plate 7, reducing the impact force.

[0026] The conveying equipment feeds the slurry into one side of the dewatering screen frame 3. During the falling process, the slurry comes into contact with the buffer plate 7 and is blocked by the buffer plate 7 before falling to the upper side of the screen 33 inside the dewatering screen frame 3. The buffer plate 7 provides obstruction to prevent the slurry from directly contacting the screen 33 and causing a large potential energy impact on the screen 33.

[0027] By adopting the above technical solution, the buffer assembly also includes a mounting block 5. One side of the mounting block 5 is fixedly connected to the side wall of the mounting plate 4. The side of the mounting block 5 away from the mounting plate 4 is slidably connected to the mounting frame 6. One side of the mounting frame 6 is fixedly connected to the support plate 61. One side of the support plate 61 is fixedly connected to the side wall of the buffer plate 7. An elastic sheet 51 is fixedly connected inside the mounting frame 6. One side of the elastic sheet 51 is fixedly connected to the side wall of the mounting block 5.

[0028] By using the buffer plate 7, mounting frame 6, elastic sheet 51 and mounting block 5 installed at the slurry discharge point, the potential energy of the slurry impact can be converted into the elastic potential energy of the elastic sheet 51, thereby absorbing part of the gravitational potential energy of the slurry and preventing the screen 33 from deforming or breaking under force when the slurry comes into contact with the screen 33.

[0029] To prevent the slurry feed from being fixed in one position relative to the screen 33, an electric push rod 8 is fixedly connected to one side of the mounting plate 4. Activating the electric push rod 8 moves the mounting plate 4, which in turn moves the mounting block 5 at its lower end. The mounting block 5 then moves the buffer plate 7 laterally for adjustment. When the slurry feeds into contact with the adjusted buffer plate 7 again, the slurry is obstructed and falls to a new position. This changes the contact position between the slurry and the screen 33, thus preventing continuous impact on one area of ​​the screen 33. This prevents high-intensity impact loads from causing a certain area of ​​the screen 33 to bear mechanical stress exceeding the design range for an extended period, which could lead to deformation or breakage of the screen 33.

[0030] By adopting the above technical solution, the electric push rod 8 is fixedly installed on the upper end of the protective frame 9, and the front and rear parts of the protective frame 9 are fixedly connected to the fixing block, and the fixing block is fixedly installed on one side of the support block 2. The protective frame 9 and the fixing block are used to fix the electric push rod 8.

[0031] The implementation principle of the dewatering screen for mineral processing in this application embodiment is as follows: Figure 1 To illustrate, the conveying equipment feeds the slurry from one side of the dewatering screen frame 3. During its descent, the slurry contacts the buffer plate 7 and, after being blocked by the buffer plate 7, falls onto the upper side of the screen 33 inside the dewatering screen frame 3. The buffer plate 7 provides obstruction, preventing the slurry from directly contacting the screen 33 and causing a large potential energy impact on the screen 33. Furthermore, when the buffer plate 7 is impacted by the slurry, it also pushes the mounting frame 6 on one side, causing the mounting frame 6 to compress the elastic sheet 51, converting the potential energy of the slurry impact into the elastic potential energy of the elastic sheet 51. This absorbs some of the gravitational potential energy of the slurry, preventing the slurry from contacting the screen 33 and causing... The screen 33 may deform or break under stress. Afterwards, the electric push rod 8 can be activated at regular intervals to move the mounting plate 4. The mounting plate 4 moves the mounting block 5 at the lower end, and the mounting block 5 moves the buffer plate 7 laterally for adjustment. When the slurry comes into contact with the adjusted buffer plate 7 again, the slurry will fall to a new position after being obstructed. That is, the contact position between the slurry and the screen 33 changes, thereby avoiding continuous impact on one place of the screen 33. This prevents high-intensity impact loads from causing a certain area of ​​the screen 33 to bear mechanical stress exceeding the design range for a long time, which could lead to deformation or breakage of the screen 33.
