Description

Technical Field

[0001] This utility model relates to the field of sintered stone production technology, specifically to a packing device for sintered stone production. Background Technology

[0002] Sintered stone is a new type of inorganic non-metallic material with excellent properties such as high strength, wear resistance, and high temperature resistance. Its production process integrates advanced technology and strict quality control. The main raw materials of sintered stone include inorganic minerals such as quartz sand, feldspar, calcium carbonate, and clay. These raw materials must undergo strict screening to ensure purity and stable composition. For example, quartz sand provides hardness, and feldspar acts as a flux to lower the firing temperature. The raw materials are first crushed into small pieces by a crusher, and then ground into fine powder by a ball mill. The particle size is usually controlled above 200 mesh to ensure the uniformity of subsequent molding and sintering. When adding raw materials into the ball mill, in order to improve the filling efficiency, a loader is often used to put a large amount of raw materials into the ball mill at once. This process generates a lot of dust in the air, causing serious environmental pollution. Some manufacturers use screw conveyors for filling, but on the one hand, the filling efficiency is significantly lower than that of using a loader, and on the other hand, the space is more limited, and it cannot be restricted by the position of the raw material pile like a loader. Utility Model Content

[0003] The purpose of this invention is to provide a packing device for sintered stone production to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a filling device for slab production, comprising an inclined hopper, an extension cover fixedly installed at the top of the inclined hopper, the interior of the extension cover communicating with the interior of the inclined hopper, the extension cover occupying only half of the space at the top of the inclined hopper, a negative pressure head one fixedly installed on the right inner wall of the inclined hopper, a negative pressure head two fixedly installed on the right inner wall of the extension cover, metal filter screens fixedly installed at the left openings of both negative pressure heads one and two, a row of vent pipes connected to the right side of both negative pressure heads one and two, an electromagnetic pulse valve installed at the port of the vent pipes, a negative pressure assembly installed outside the inclined hopper, the air inlet of the negative pressure assembly communicating with the port of the electromagnetic pulse valve, and a striking assembly installed inside both negative pressure heads one and two, the striking assembly periodically striking the metal filter screen.

[0005] Furthermore, the negative pressure assembly includes a negative pressure pump, the air inlet of which is connected to a negative pressure pipe, the top end of which is connected to a diverter pipe, and the branch port of the diverter pipe is connected to the port of the electromagnetic pulse valve.

[0006] Furthermore, the striking assembly includes a fixed shaft, and the fixed shaft inside the first negative pressure head is fixedly connected to the inner wall of the first negative pressure head, and the fixed shaft inside the second negative pressure head is fixedly connected to the inner wall of the second negative pressure head. A rotating plate is rotatably sleeved on the outer wall of the fixed shaft. A baffle plate is fixedly installed at one end of the rotating plate, and a striking plate is fixedly installed at the other end. The baffle plate faces the connection between the first negative pressure head, the second negative pressure head, and the vent pipe. The striking plate is aligned with the metal filter screen. A spring is fixedly installed on the outer wall of the striking plate on the side facing away from the metal filter screen. The other end of the spring is fixedly connected to the inner wall of either the first negative pressure head or the second negative pressure head.

[0007] Furthermore, a support base is provided below the inclined hopper, and a support leg is fixedly installed on the top of the support base, with the top of the support leg fixedly connected to the bottom of the inclined hopper.

[0008] Furthermore, a flexible connecting pipe is connected to the right end port of the inclined hopper. The flexible connecting pipe is sleeved on the feed end of the ball mill, and the end of the flexible connecting pipe is clamped to the outer wall of the feed end of the ball mill by a clamp.

[0009] Furthermore, a hard silicone pad is fixedly installed on the outer wall of the striking plate facing the metal filter screen, a soft rubber pad is fixedly installed on the outer wall of the shielding plate facing away from the metal filter screen, and a limiting ring is fixedly sleeved on the outer wall of the fixed shaft, with the limiting ring blocking both sides of the rotating plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Dust floating in the air will also enter the inclined hopper and extended hood with the air, and then be filtered out by the metal filter screen, causing the dust to fall into the inclined hopper and extended hood. The dust in the extended hood can also fall into the inclined hopper. This design can significantly suppress dust splashing, while retaining the advantages of the loader filler.

[0012] 2. When the electromagnetic pulse valve is open, the air pipe is under negative pressure with negative pressure head one and negative pressure head two. Under negative pressure, the baffle plate will move closer to the right inner wall of negative pressure head one and negative pressure head two, causing the rotating plate to rotate. The rotation of the rotating plate drives the striking plate to move, causing the striking plate to separate from the metal filter screen, thereby squeezing the spring. When the electromagnetic pulse valve is closed next time, the spring releases its elasticity and pushes the striking plate to reset, causing the striking plate to strike the metal filter screen, thereby vibrating the metal filter screen and shaking off the dust on the metal filter screen. Since both negative pressure head one and negative pressure head two are equipped with a row of air pipes, by controlling the opening and closing of the electromagnetic pulse valves on one row of air pipes asynchronously, multiple vibrations of the metal filter screen can be achieved, improving the dust removal efficiency of the metal filter screen.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-6This utility model provides a technical solution: a filling device for slab production, including an inclined hopper 2, an extension cover 3 fixedly installed at the top of the inclined hopper 2, the interior of the extension cover 3 communicating with the interior of the inclined hopper 2, the extension cover 3 occupying only half of the space at the top of the inclined hopper 2, a negative pressure head 4 fixedly installed on the right inner wall of the inclined hopper 2, a negative pressure head 5 fixedly installed on the right inner wall of the extension cover 3, a metal filter screen 10 fixedly installed at the left opening of both negative pressure heads 4 and 5, a row of vent pipes 6 connected to the right side of both negative pressure heads 4 and 5, an electromagnetic pulse valve 7 installed at the port of the vent pipes 6, a negative pressure component 8 installed outside the inclined hopper 2, the air inlet of the negative pressure component 8 communicating with the port of the electromagnetic pulse valve 7, and a striking component 9 installed inside both negative pressure heads 4 and 5, the striking component 9 periodically striking the metal filter screen 10, the inclined hopper 2... Used to catch the raw materials dumped by the forklift, the extension hood 3 can also block some of the rising and splashing dust. The negative pressure component 8 draws air into the negative pressure head 4 and negative pressure head 5, so that the negative pressure head 4 and negative pressure head 5 are in a negative pressure state at the metal filter screen 10. The raw materials are heavier and not easily affected by the negative pressure, while the air is easily affected by the negative pressure and is sucked into the negative pressure head 4 and negative pressure head 5. The dust floating in the air will also enter the inclined hopper 2 and the extension hood 3 with the air, and then be filtered out by the metal filter screen 10, so that the dust falls into the inclined hopper 2 and the extension hood 3. The dust in the extension hood 3 can also fall into the inclined hopper 2. This design can significantly suppress the splashing of dust, while retaining the advantages of the forklift filler. The impact component 9 is set to periodically impact the metal filter screen 10 to shake off the dust adsorbed on the metal filter screen 10 and prevent the dust from clogging the filter holes on the metal filter screen 10.

[0022] The negative pressure assembly 8 includes a negative pressure pump 801. The air inlet of the negative pressure pump 801 is connected to a negative pressure pipe 802. The top end of the negative pressure pipe 802 is connected to a diversion pipe 803. The branch port of the diversion pipe 803 is connected to the port of the electromagnetic pulse valve 7. When the negative pressure pump 801 works, it draws out the air in the negative pressure pipe 802, and then draws out the air in the diversion pipe 803. The diversion pipe 803 is connected to the ventilation pipe 6 through the electromagnetic pulse valve 7, which can draw out the air in the negative pressure head 4 and negative pressure head 5 connected to the ventilation pipe 6, so that the negative pressure head 4 and negative pressure head 5 are in a negative pressure state at the metal filter screen 10.

[0023] The striking assembly 9 includes a fixed shaft 901, which is fixedly connected to the inner wall of the negative pressure head 4. The fixed shaft 901 in the negative pressure head 5 is also fixedly connected to the inner wall of the negative pressure head 5. A rotating plate 902 is rotatably sleeved on the outer wall of the fixed shaft 901. A baffle plate 903 is fixedly installed at one end of the rotating plate 902, and a striking plate 904 is fixedly installed at the other end. The baffle plate 903 faces the connection point between the negative pressure head 4, the negative pressure head 5, and the ventilation pipe 6. The striking plate 904 is aligned with the metal filter screen 10. A spring 905 is fixedly installed on the outer wall of the side of the striking plate 904 facing away from the metal filter screen 10. The other end of the spring 905 is fixedly connected to the inner wall of the negative pressure head 4 or the negative pressure head 5. When the electromagnetic pulse valve 7 is in the closed phase, the negative pressure at the connection between the vent pipe 6 and the negative pressure head 4 or the negative pressure head 5 disappears. At this time, the elastic force of the spring 905 will pull the striking plate 904 to move, so that the striking plate 904 and the metal filter screen... When the electromagnetic pulse valve 7 is open, the ventilation pipe 6 is in a negative pressure state with the negative pressure head 4 and the negative pressure head 5. Under negative pressure, the baffle plate 903 will move closer to the right inner wall of the negative pressure head 4 and the negative pressure head 5, thereby causing the rotating plate 902 to rotate. The rotation of the rotating plate 902 drives the striking plate 904 to move, causing the striking plate 904 to separate from the metal filter screen 10, thereby squeezing the spring 905. When the electromagnetic pulse valve 7 is closed next time, the spring 905 releases its elastic force to push the striking plate 904 to reset, so that the striking plate 904 strikes the metal filter screen 10, thereby vibrating the metal filter screen 10 and shaking off the dust on the metal filter screen 10. Since the negative pressure head 4 and the negative pressure head 5 are each equipped with a row of ventilation pipes 6, by controlling the opening and closing of the electromagnetic pulse valve 7 on the row of ventilation pipes 6 to be asynchronous, multiple vibrations of the metal filter screen 10 can be achieved, thereby improving the dust removal efficiency of the metal filter screen 10.

[0024] A support base 14 is provided below the inclined hopper 2, and a support leg 15 is fixedly installed on the top of the support base 14. The top of the support leg 15 is fixedly connected to the bottom of the inclined hopper 2. The support base 14 is provided to install the support leg 15, thereby supporting and fixing the inclined hopper 2.

[0025] A flexible connecting pipe 16 is connected to the right end port of the inclined hopper 2. The flexible connecting pipe 16 is sleeved on the feed end of the ball mill 1. The end of the flexible connecting pipe 16 is clamped to the outer wall of the feed end of the ball mill 1 by a clamp 17. The flexible connecting pipe 16 is used to connect the right end port of the inclined hopper 2 and the feed port of the ball mill 1, thereby reducing the mutual interference between the ball mill 1 and the inclined hopper 2 and preventing the vibration of the inclined hopper 2 from being transmitted to the ball mill 1.

[0026] A hard silicone pad 12 is fixedly installed on the outer wall of the impact plate 904 facing the metal filter screen 10. A soft rubber pad 13 is fixedly installed on the outer wall of the shield plate 903 facing away from the metal filter screen 10. A limiting ring 11 is fixedly sleeved on the outer wall of the fixed shaft 901. The limiting ring 11 blocks both sides of the rotating plate 902. The soft rubber pad 13 is set to prevent the shield plate 903 from hitting the inner wall of the negative pressure head 4 or the negative pressure head 5. The hard silicone pad 12 can transmit vibration to the metal filter screen 10 on the one hand, and reduce damage to the metal filter screen 10 on the other hand. The limiting ring 11 is set to limit the rotating plate 902 and prevent the rotating plate 902 from sliding relative to the fixed shaft 901.

[0027] Working Principle: During operation, before the loader dumps the raw material into the inclined hopper 2, the negative pressure pump 801 is activated to remove air from the negative pressure pipe 802, and subsequently from the diversion pipe 803. The diversion pipe 803 is connected to the vent pipe 6 via the electromagnetic pulse valve 7, thus removing air from the negative pressure heads 4 and 5 connected to the vent pipe 6. This creates a negative pressure state at the metal filter screen 10 at negative pressure heads 4 and 5. Then, the loader dumps the raw material into the inclined hopper 2. Firstly, the extended hood 3 intercepts most of the splashing dust. Because of the negative pressure at negative pressure heads 4 and 5, air is drawn in, attracting the splashing dust to them. The metal filter screen 10 then filters out the dust. During this process, multiple electromagnetic pulse valves 7 open and close at asynchronous pulse frequencies. When the electromagnetic pulse valve 7 is open, the vent pipe 6 and the negative pressure heads... The pressure between the first negative pressure head 4 and the second negative pressure head 5 is in a negative pressure state. Under the negative pressure state, the baffle plate 903 will move closer to the right inner wall of the first negative pressure head 4 and the second negative pressure head 5, thereby causing the rotating plate 902 to rotate. The rotation of the rotating plate 902 drives the striking plate 904 to move, causing the striking plate 904 to separate from the metal filter screen 10, thereby squeezing the spring 905. When the electromagnetic pulse valve 7 is in the closed period next time, the spring 905 releases its elastic force to push the striking plate 904 to reset, so that the striking plate 904 strikes the metal filter screen 10, thereby vibrating the metal filter screen 10 and shaking off the dust on the metal filter screen 10. The electromagnetic pulse valve 7 of different frequencies can also make the corresponding striking components 9 strike the metal filter screen 10 at different frequencies to achieve multi-frequency vibration and improve dust removal efficiency. The raw material entering the inclined hopper 2 enters the feed port of the ball mill 1 through the soft connecting pipe 16, and the ball mill 1 grinds the raw material.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
