Description

Technical Field

[0001] This utility model relates to the field of sintered colored sand production technology, and in particular to a filtration device for sintered colored sand production. Background Technology

[0002] The main components of sound-insulating and noise-reducing silicon crystal boards are calcium powder, pulp, and a small amount of cement. They are formed into a high-density substrate through high temperature and pressure, and the surface treatment is an odorless and non-toxic melamine film. Their convenience, environmental friendliness, comfort, aesthetic appeal, and sound insulation properties have made them widely popular, changing many people's renovation experience. The calcium powder used is mostly sintered colored sand, which is made from mineral particles as raw materials, with the addition of inorganic pigments and special coatings, and then sintered at high temperatures. It is mainly used in various colored epoxy flooring, real stone paint, various architectural coatings, sandstone slabs, ABS modified felt, waterproof membranes, colored sand paintings, and various high-end handicrafts. It features bright colors, strong weather resistance, wear resistance, acid and alkali resistance, slip resistance, seamlessness, and a high-end aesthetic. Sintered colored sand needs to be strictly screened through a vibration filtration device to ensure it is suitable for the production needs of sound-insulating and noise-reducing silicon crystal boards of different sizes.

[0003] Existing vibrating filter devices in sintered colored sand production operate on a relatively simple principle. They typically only have one set of screens, and after each feeding operation, they can only separate sintered colored sand particles of one size based on the aperture size of this set of screens. When facing a market demand for different particle sizes, existing vibrating filter devices cannot simultaneously meet this demand and cannot separate sintered colored sand particles of multiple sizes in a single operation. This leads to low production efficiency, requiring frequent screen replacements and repeated operations, which seriously affects production progress and cost control. Therefore, a filter device for sintered colored sand production is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a filtration device for the production of sintered colored sand, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A filtration device for the production of sintered colored sand includes a base plate, a screen frame above the base plate, and a first screen, a second screen, and a third screen fixedly installed sequentially inside the screen frame. The first screen, the second screen, and the third screen have different mesh sizes. Three funnels are fixedly installed on the bottom side of the screen frame, respectively below the first screen, the second screen, and the third screen. Each of the three funnels is fixedly connected to a discharge pipe on its bottom side, and a collection assembly is installed below the three discharge pipes. Two side plates are fixedly installed on one side of the base plate, and a striking assembly is installed between the two side plates. A baffle assembly is installed above the screen frame.

[0007] Preferably, the collection assembly includes a collection box disposed below the base plate, two partitions are fixedly installed inside the collection box, the collection box is divided into three areas by the two partitions, and three discharge pipes are directed toward the three areas in sequence.

[0008] Preferably, the striking assembly includes a motor fixedly installed on one side of a side plate, the output end of the motor rotatably passing through one side plate and rotatably connected to one side of another side plate, multiple striking plates fixedly installed on the outside of the output end of the motor, and a rubber pad fixedly installed on the bottom side of the screen frame, with the rubber pad located above the multiple striking plates.

[0009] Preferably, the partition assembly includes a fixed frame fixedly installed on the top side of the screen frame, two insertion holes opened on the top side of the fixed frame, and a feed inlet provided on the top side of the fixed frame, with the feed inlet facing the first screen.

[0010] Preferably, two fixing frames are fixedly installed on the top side of the fixing frame. Both fixing frames are L-shaped. A first electric push rod and a second electric push rod are fixedly installed on the top side of the two fixing frames, respectively. The output ends of the first electric push rod and the second electric push rod pass through the fixing frame and are respectively fixedly connected to a first baffle and a second baffle. The first baffle and the second baffle are respectively located in two insertion holes. The bottom sides of the first baffle and the second baffle are respectively in contact with the top sides of the second screen and the third screen.

[0011] Preferably, two first springs and two second springs are fixedly installed on the top side of the bottom plate, and the top ends of the two first springs and two second springs are fixedly connected to the bottom side of the screen frame.

[0012] Preferably, a set of limiting plates is fixedly installed on both sides of the base plate, and there are two limiting plates in each set. The opposite surfaces of the two sets of limiting plates are respectively attached to the two sides of the screen frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting up a first screen, a second screen, and a third screen, each with different screen openings, three types of sintered colored sand of different sizes can be separated in one operation. The motor drives the impact plate to strike the screen frame, which, together with the first and second springs, makes the screen frame shake fully, ensuring that the colored sand is fully filtered by each screen. Compared with traditional single-screen devices, there is no need to frequently change screens, which greatly improves production efficiency. It can also work continuously and efficiently, greatly promote the production progress, reduce time and labor costs, and meet the market demand for sintered colored sand with multiple particle sizes.

[0015] 2. The collection box is divided into three areas by partitions, each corresponding to a discharge pipe. These areas can store sintered colored sand filtered through different screens. The first and second electric push rods of the partition assembly, along with the connected first and second baffles, can effectively control the flow of colored sand between the screens, ensuring that each screen accurately screens the colored sand in sequence. The limiting plate can prevent the screen frame from twisting excessively, thus ensuring stable filtration. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-4A filtration device for the production of sintered colored sand includes a base plate 1, a screen frame 4 above the base plate 1, and a first screen 5, a second screen 6, and a third screen 7 sequentially fixedly installed inside the screen frame 4. The screen meshes of the first screen 5, second screen 6, and third screen 7 are different. Three funnels 15 are fixedly installed on the bottom side of the screen frame 4, located below the first screen 5, second screen 6, and third screen 7, respectively. A discharge pipe 16 is fixedly connected to the bottom side of each of the three funnels 15, and a collection assembly is installed below the three discharge pipes 16. Two side plates 19 are fixedly installed on one side of the base plate 1, and a striking assembly is installed between the two side plates 19. A baffle assembly is installed above the screen frame 4. The first screen 5... The second screen 6 and the third screen 7 can separate sintered colored sand of three different sizes. The first screen 5 has the smallest aperture, which intercepts the larger particles first, allowing the smaller particles to pass through first, completing the initial screening. Then, the colored sand that fails to pass through the first screen 5 falls to the second screen 6, which has a moderate aperture, and can further screen out colored sand of the appropriate size. Finally, the remaining larger particles are retained on the third screen 7. These three screens work together in sequence, and in one operation, the sintered colored sand can be accurately classified according to size. In this way, the production efficiency is greatly improved, and there is no need to change the screens frequently as in traditional equipment. It can effectively meet the needs of different industries for sintered colored sand of various particle sizes, effectively promote production progress, and reduce costs.

[0023] Specifically, the collection component includes a collection box 17 located below the base plate 1. Two partitions 18 are fixedly installed inside the collection box 17, which is divided into three areas by the two partitions 18. Three discharge pipes 16 are arranged in sequence towards the three areas. The two partitions 18 divide the collection box 17 into three areas, thereby enabling the separate placement of three types of sintered colored sand with different volumes. This allows subsequent personnel to directly take out the same volume of sintered colored sand from one area for use.

[0024] Specifically, the striking assembly includes a motor 20 fixedly installed on one side of a side plate 19. The output end of the motor 20 rotates through one side plate 19 and is rotatably connected to one side of another side plate 19. Multiple striking plates 21 are fixedly installed on the outside of the output end of the motor 20. A rubber pad 22 is fixedly installed on the bottom side of the screen frame 4. The rubber pad 22 is located above the multiple striking plates 21. By setting multiple striking plates 21, when the sintered colored sand is placed and needs to be filtered, the motor 20 can drive the multiple striking plates 21 to rotate in a cycle. During the cycle rotation, the multiple striking plates 21 will strike the bottom of the screen frame 4. Under the action of two sets of springs, a shaking will be generated, thereby achieving the filtration of sintered colored sand. The rubber pad 22 fixedly installed on the bottom side of the screen frame 4 can replace the screen frame 4 to be struck by the multiple striking plates 21, thereby effectively reducing the noise generated by directly striking the screen frame 4.

[0025] Specifically, the baffle assembly includes a fixed frame 8 fixedly installed on the top side of the screen frame 4. Two insertion holes are provided on the top side of the fixed frame 8. A feed inlet 9 is provided on the top side of the fixed frame 8, facing the first screen 5. Two fixed brackets 10 are fixedly installed on the top side of the fixed frame 8. Both fixed brackets 10 are L-shaped. A first electric push rod 11 and a second electric push rod 12 are respectively fixedly installed on the top side of the two fixed brackets 10. The output ends of the first electric push rod 11 and the second electric push rod 12 both pass through the fixed bracket 10 and are respectively fixedly connected to the first electric push rod 11. A first baffle 13 and a second baffle 14 are respectively located in two insertion holes. The bottom sides of the first baffle 13 and the second baffle 14 are respectively attached to the top sides of the second screen 6 and the third screen 7. By setting the first baffle 13 and the second baffle 14, when the sintered colored sand is located on one of the surfaces of the first screen 5, the second screen 6 or the third screen 7, the first baffle 13 and the second baffle 14 will always be in a closed state, so that the sintered colored sand can be filtered by the three screens respectively.

[0026] Specifically, two first springs 2 and two second springs 3 are fixedly installed on the top side of the base plate 1. The top ends of the two first springs 2 and two second springs 3 are fixedly connected to the bottom side of the screen frame 4. A set of limiting plates 23 are fixedly installed on both sides of the base plate 1. There are two limiting plates 23 in each set. The opposite surfaces of the two sets of limiting plates 23 are respectively attached to the two sides of the screen frame 4. With the two first springs 2 and two second springs 3, when the motor 20 runs and drives the striking plate 21 to strike the screen frame 4, the two first springs 2 and two second springs 3 will extend and retract with the striking plate 21. During this extension and retraction process, the screen frame 4 can be shaken sufficiently, so that the sintered colored sand in the screen frame 4 can be fully filtered by the three screens. At the same time, the device is equipped with two sets of limiting plates 23, which can limit the screen frame 4 and prevent the screen frame 4 from twisting excessively under the action of the first springs 2 and the second springs 3, ensuring the stable shaking of the screen frame 4 and ensuring the smooth filtration process of the sintered colored sand.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0028] In use: When filtering sintered colored sand, first pour the sintered colored sand into the screen frame 4 through the feed inlet 9. At this time, the sintered colored sand will remain on the surface of the first screen 5. Then, start the motor 20. Multiple striking plates 21 fixedly installed on the outside of the output end of the motor 20 will rotate accordingly. The multiple striking plates 21 will cyclically strike the bottom side of the screen frame 4. Under the action of the two first springs 2 and the two second springs 3, the screen frame 4 will shake, and the sintered colored sand on the first screen 5 will also shake synchronously. Since the screen holes on the surface of the first screen 5 are smaller than the screen holes on the surface of the second screen 6, the sintered colored sand will continuously... During the shaking process, some smaller sintered colored sand will be filtered out by the first screen 5. This filtered sintered colored sand flows along the funnel 15 at the bottom of the first screen 5 into the collection box 17. Once all the smaller sintered colored sand has been filtered out, the first electric push rod 11 is activated, causing the first baffle 13 to move upwards. At this time, some moderately sized and larger sintered colored sand on the surface of the first screen 5 will slide down due to inertia to the surface of the second screen 6. After all the sand has slid down, the first electric push rod 11 is activated again, causing the first baffle 13 to move downwards, removing smaller sintered colored sand. Medium and large-volume sintered colored sand is intercepted on the surface of the second screen 6. As multiple impact plates 21 continuously strike the screen frame 4, some medium-volume sintered colored sand is filtered by the second screen 6 and then flows along the funnel 15 at the bottom of the second screen 6 to the discharge pipe 16, and then flows into the collection box 17 through the discharge pipe 16. After the medium-volume sintered colored sand has been filtered, the second electric push rod 12 is started. The second electric push rod 12 drives the second baffle 14 to move upward, and the larger-volume sintered colored sand slides onto the surface of the third screen 7. Then, the second electric push rod 12 is started again, carrying... The second baffle 14 moves down, causing the larger volume of sintered colored sand to remain on the surface of the third screen 7. The larger volume of sintered colored sand is then filtered by the third screen 7. The filtered colored sand flows along the funnel 15 at the bottom of the third screen 7 into the discharge pipe 16, and finally flows into the collection box 17 from the discharge pipe 16. This completes the filtration process of the sintered colored sand. By setting the first screen 5, the second screen 6 and the third screen 7, three types of sintered colored sand with different volumes can be separated. The collection box 17 is divided into three areas by the partition 18, which can be used to place these three types of sintered colored sand with different volumes respectively.
