Description

Technical Field

[0001] This invention relates to the field of covering agent production technology, specifically to a vibrating screen for covering agent production and its usage. Background Technology

[0002] Covering agent is a covering material used in casting production to extend the solidification time of molten metal in risers. It is applied to the surface of the molten metal in the riser. After the covering agent is produced, some of it may stick together to form lumps. To ensure that the covering agent can be used properly, a vibrating screen is needed for screening.

[0003] According to Chinese Patent Publication No. CN218963227U, this patent provides a vibrating screen mechanism for producing a covering agent, including a housing and two vibrating pumps. The two vibrating pumps are fixedly connected to the outer wall of one side of the housing. Sliding grooves are formed on both inner walls of the housing, and a screen is movably connected within each sliding groove. Two clearance grooves are formed on one side of the housing, and these clearance grooves communicate with the sliding grooves. A slider is movably connected within each of the two clearance grooves, and the slider is fixed to the screen. A second spring is fixedly connected to one side of each slider, and the second spring is fixed to the clearance groove. One of the clearance grooves... A protrusion is movably connected within the slot. A motor is fixedly connected to one outer wall of the housing, and one end of the motor output shaft passes through the housing and is fixed to the protrusion. A rotating slot is provided on the top of the housing, and a rotating rod is movably connected within the rotating slot. A scraper is fixedly connected to the bottom end of the rotating rod. A torsion spring is sleeved on the outside of the rotating rod, and both ends of the torsion spring are fixed to the rotating rod and the rotating slot, respectively. A fixing block is fixedly connected to the upper surface of the screen. Two upper support columns are fixedly connected to both outer walls of the housing. A first spring is fixedly connected to the bottom of each of the upper support columns, and a base is fixedly connected to the bottom end of the first spring. The base has a fixed foot fixedly connected to its bottom, and the upper surface of the fixed foot has multiple fixing holes. The upper surface of the box body has a funnel fixedly connected to it and the funnel is connected to the box body. A first discharge pipe is fixedly connected to one side of the box body and the first discharge pipe is connected to the box body. A second discharge pipe is fixedly connected to one side of the box body and the second discharge pipe is connected to the box body. The bottom inner wall of the box body has a sloping groove, and the sloping groove corresponds to the second discharge pipe. A sloping frame is fixedly connected inside the box body and the sloping frame corresponds to the first discharge pipe. By setting up the scraper, starting the motor drives the convex block to rotate, which in turn pushes the slider to move. The slider then moves the screen, and the screen, through the fixed block, pushes the scraper to rotate. Subsequently, the scraper reverses direction due to the force of the torsion spring, and this cycle repeats, allowing the scraper to remove the covering agent on the screen, preventing its accumulation and improving the screening effect of the vibrating screen mechanism. The first spring reduces the vibration effect of the vibrating pump on the base when the vibrating pump is started, making the vibrating screen mechanism more stable and improving its operational stability. Through the combined use of the inclined chute and inclined frame, which are inclined, the covering agent screened out and the unscreened covering agent are discharged from the second and first discharge pipes respectively under the action of the inclined chute and inclined frame, facilitating the discharge of the screening covering agent and improving the ease of discharge from the vibrating screen mechanism.

There are two support plates 1, and a partition plate 5 is fixedly installed on the top right side of each of the two support plates 1. The top of the two partition plates 5 is fixedly connected to the bottom right side of the installation plate 4. The partition plates 5 are used to lift the dust collection mechanism 2 upward by a certain distance to reserve working space for the linear motor 6.

[0042] In this embodiment, by activating the dust extraction fan 206, a local negative pressure suction is formed in the bottom area of ​​the crossbeam 205, thereby adsorbing the dust generated during the screening process and allowing the dust to enter the dust collection box 208 along the dust pipe 207 for centralized collection, preventing it from overflowing and spreading into the space, reducing the dust pollution level in the working area, and improving the cleanliness of the working environment.

[0043] Example 2

[0044] like Figure 1 , 5As shown in Figures 6 and 7, based on Embodiment 1, the present invention provides a technical solution: Preferably, a linear motor 6 is fixedly installed on the top left side of each of the two support plates 1, and a movable plate 7 is fixedly installed on the moving end of each of the two linear motors 6. The two movable plates 7 are symmetrically arranged with respect to each other. When the linear motor 6 is started, its moving end drives the movable plate 7 to reciprocate. A screening mechanism 8 is provided on the movable plate 7, and the screening mechanism 8 includes a screening box 801. The bottom of the two movable plates 7 that are close to each other is fixedly connected to the left side of the top edge of the screening box 801. The four corners of the inner wall of the screening box 801 are respectively fixed. A connecting plate 1 802 and a connecting plate 2 806 are connected.

[0045] In this embodiment, by starting the linear motor 6, the moving end of the motor drives the moving plate 7 to reciprocate. The moving plate 7 drives the screening box 801 to reciprocate between the two support plates 1, so that the falling covering agent sways left and right on the screen plate 804, which increases the screening efficiency and avoids the problem of the covering agent accumulating together and causing the mesh to be blocked.

[0046] Example 3

[0047] like Figure 1 , 5 As shown in Figures 6 and 7, based on Embodiment 1, the present invention provides a technical solution: Preferably, an electric push rod 807 is fixedly installed at the bottom of each connecting piece 2 806. The top end of the inner rod of each electric push rod 807 movably passes through the top of the adjacent connecting piece 2 806 and abuts against the bottom of the screen plate 804. Sliding arms 808 are fixedly connected to the front and back of the outer wall of the screening box 801. The electric push rod 807 reciprocates and extends, pushing the screen plate 804 to form a rapid vibration effect under the elastic force of the spring 805. The discharge hood 2 The bottom opening of 04 extends into the opening of the screening box 801. The bottom opening of the screening box 801 allows the covering agent to fall into the screening box 801 through the discharge hood 204. A chute 9 is provided on the side of the two support plates 1 that are close to each other. Two sliding arms 808 are slidably connected to the inner walls of the two chute 9.

A receiving groove 10 is fixedly connected to the bottom of the side of the two support plates 1 that are close to each other. The screened covering agent will fall through the mesh into the receiving groove 10 for centralized collection.

[0048] In this embodiment, by activating the electric push rod 807, its inner rod reciprocates and extends, thereby pushing the screen plate 804 to move longitudinally. Under the elastic force of the spring 805, the screen plate 804 is always pushed to generate a downward reset force. Combined with the push of the electric push rod 807, a rapid vibration effect is formed, which accelerates the screening of the covering agent. The screened covering agent will pass through the mesh and fall into the collection tank 10 for centralized collection.

[0049] Example 4

[0050] Based on Examples 1 to 3, the present invention provides a technical solution: a method of using a vibrating screen for producing a covering agent, comprising the following steps:

[0051] S1. The covering agent is put into the feed hole 202, and it rolls along the feed plate 203 to the discharge port to the discharge cover 204 and falls into the screening box 801. The dust suction fan 206 is started, and the linear motor 6 is started to drive the moving plate 7 to reciprocate, which drives the screening box 801 to reciprocate between the two support plates 1, so that the falling covering agent will sway left and right on the screen plate 804.

[0052] S2. Start the electric push rod 807, so that its inner rod reciprocates and extends. Under the elastic force of the spring 805, the screen plate 804 is pushed to always generate a downward reset force. Combined with the push of the electric push rod 807, a rapid vibration effect is formed. The screened covering agent will pass through the mesh and fall into the collection tank 10 for centralized collection.

[0053] S3. The vacuum fan 206 creates a local negative pressure suction in the bottom area of ​​the crossbeam 205, thereby adsorbing the dust generated during the screening process and causing the dust to enter the dust collection box 208 along the dust pipe 207 for centralized collection. Opening the box door 3 allows for the recycling of the dust in the dust collection box 208.

[0054] The working principle of the vibrating screen used in the production of this covering agent and its usage will be explained in detail below.

[0055] like Figure 1-7As shown, the covering agent is fed into the feeding box 201 through the feed hole 202, causing it to roll along the feed plate 203 towards the discharge port and fall into the screening box 801 through the discharge hood 204. The dust suction fan 206 is activated, creating a local negative pressure suction in the bottom area of ​​the crossbeam 205, thereby adsorbing the dust generated during the screening process and causing the dust to enter the dust collection box 208 along the dust pipe 207 for centralized collection, preventing overflow and diffusion into the space, reducing dust pollution in the working area, and improving the cleanliness of the working environment. The dust in the dust collection box 208 can be collected and processed by opening the box door 3, making it convenient to clean the contents of the dust collection box 208. The linear motor 6 is activated, causing its moving end to drive the moving plate 7 to reciprocate, so that the moving plate 7 reciprocates through the gap between the mounting plate 4 and the support plate 1, avoiding jamming and impact. The partition plate 5 is used to lift the dustproof mechanism 2 upward by a certain distance, leaving room for the linear motor 6. In the working space, the movable plate 7 drives the screening box 801 to reciprocate between the two support plates 1, and the two sliding arms 808 limit the sliding within the two sliding grooves 9 to improve the stability of movement. This causes the falling covering agent to sway left and right on the screen plate 804, increasing the screening efficiency and preventing the covering agent from accumulating and clogging the mesh. At the same time, the electric push rod 807 is activated, causing its inner rod to reciprocate and extend, thereby pushing the screen plate 804 to move longitudinally. Under the elastic force of the spring 805, the screen plate 804 is always pushed to generate a downward reset force. Combined with the push of the electric push rod 807, a rapid vibration effect is formed, which accelerates the screening of the covering agent. The screened covering agent will fall through the mesh into the receiving tank 10 for centralized collection. The screened covering agent can be taken out as needed. The dust collection box 208 is placed independently on the left side of the two support plates 1, which facilitates the disassembly of the dust pipe 207 and the periodic transfer and cleaning of the dust collection box 208.
