Description

Technical Field

[0001] This utility model relates to the field of ceramic tile raw material screening technology, specifically a ceramic tile raw material screening device. Background Technology

[0002] Different particle sizes of ceramic tile raw materials (such as clay, quartz, feldspar, etc.) play different roles in the body. Specifically, coarser particles (such as 1-2 mm in diameter) can act as a skeleton to enhance the strength of the body and reduce drying shrinkage; medium particles (such as 0.1-1 mm in diameter) can be used to fill the gaps between particles and balance the structure; fine particles (such as less than 0.1 mm in diameter) can be used to improve the density of the body and ensure a smooth surface after firing. Therefore, it is necessary to classify and use different ceramic tile raw materials according to their particle size.

[0003] In the prior art, utility model patent (CN218531832U) discloses a multi-stage screening structure for ceramic tile production, including a screening box. The screening box has a feed inlet in the middle of its upper end. A screening component is provided in the lower middle of the inner surface of the screening box. Dust scraping components are provided on both sides of the lower lower surface of the screening box. Multiple sets of support legs are provided on the lower outer surface of the screening box. A screening component is provided on the middle outer surface of the lower end of the screening box. This screening structure is not convenient for cleaning particles from the screen mesh.

[0025] 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.

[0026] Example 1

[0027] Please see Figure 1-5 A ceramic tile raw material screening device includes a frame 6, a screening mechanism 1 elastically connected to the frame 6, and a vibration unit 2 connected to the screening mechanism 1. The screening mechanism 1 is provided with a sieve plate 11 and a collection trough 12. The collection trough 12 is located below the sieve plate 11. A collection port 121 communicating with the collection trough 12 is provided on one side of the screening mechanism 1. The screening mechanism 1 is also provided with a drive unit 15, an upper cleaning unit 4, and a lower cleaning unit 5. The drive unit 15 is located between the sieve plate 11 and the collection trough 12. The upper cleaning unit 4 and the lower cleaning unit 5 are respectively connected to the top and bottom of the drive unit 15. The drive unit 15 is used to drive the upper cleaning unit 4 and the lower cleaning unit 5 to move along the direction of the collection port 121, while cleaning the sieve plate 11 and the collection trough 12.

[0028] In practical applications, the particle size of ceramic tile raw materials varies, and different particle sizes of ceramic tile raw materials have different uses. Therefore, it is necessary to screen and classify the ceramic tile raw materials. The ceramic tile raw materials fall onto the screen plate 11, and the screen plate 11 is vibrated by the vibration unit 2, so that the ceramic tile raw materials move unidirectionally along the length of the screen plate 11. When the particle size of the ceramic tile raw materials is smaller than the mesh diameter of the screen plate 11, the ceramic tile raw materials fall below the screen plate 11, that is, onto the collection tank 12. The ceramic tile raw materials screened in this way are qualified. Specifically, the collection tank 12 can be designed to be inclined towards the collection port 121. This design allows the ceramic tile raw materials to fall onto the collection tank 12 and also move closer to the collection port 121. More specifically, an external collection device is set below the collection port 121, and qualified ceramic tile raw materials fall from the collection port 121 onto the collection device for collection.

[0029] During the screening process, due to the varying particle sizes of the ceramic tile raw materials, some may become stuck in the mesh of the sieve plate 11. After the vibration unit 2 stops working, some ceramic tile raw materials will remain on the collection tank 12. Therefore, after the vibration unit 2 stops working, the drive unit 15 is activated, thereby driving the upper cleaning unit 4 and the lower cleaning unit 5 to clean the sieve plate 11 and the collection tank 12 simultaneously. Specifically, the upper cleaning unit 4 will clean out the ceramic tile raw materials stuck in the mesh of the sieve plate 11. At this time, there are two possible outcomes for the ceramic tile raw materials: one is that they are pushed upwards above the sieve plate 11, which requires assistance from staff for cleaning; the other is that they fall onto the collection tank 12, which can be cleaned by the lower cleaning unit 5 to the collection port 121 and collected by an external collection device. This improves the lifespan of the sieve plate 11, eliminates the need for staff to disassemble the sieve plate 11 for cleaning, increases work efficiency, and reduces material waste.

[0030] Preferably, the upper cleaning unit 4 includes a connecting plate 41 and a first cleaning brush 42. The connecting plate 41 is connected to the top of the drive unit 15, and the first cleaning brush 42 is connected to the connecting plate 41. The first cleaning brush 42 abuts against the bottom of the sieve plate 11.

[0031] With the above design, the first cleaning brush 42 is connected to the drive unit 15 via the connecting plate 41. When the drive unit 15 is activated, it will drive the connecting plate 41 and the first cleaning brush 42 to move. The first cleaning brush 42 and the bottom of the sieve plate 11 abut against each other to ensure the cleaning effect. On the other hand, with this design, the first cleaning brush 42 can be set as a detachable structure, which makes it convenient to replace the first cleaning brush 42.

[0032] Preferably, the lower cleaning unit 5 is a second cleaning brush, which is connected to the bottom of the drive unit 15 and contacts the surface of the collection tank 12.

[0033] In the above design, the second cleaning brush can sweep the tile material on the collection tank 12 toward the collection port 121. On the other hand, the second cleaning brush is in contact with the surface of the collection tank 12, which can ensure the cleaning effect. Furthermore, when the collection tank 12 is designed to be inclined toward the collection port 121, the second cleaning brush can be set to abut against it, thereby ensuring that the second cleaning brush can always be in contact with the surface of the collection tank 12, thereby further ensuring the cleaning effect.

[0034] Preferably, the sieve plate 11 is provided with a plurality of first sieve holes 111, second sieve holes 112 and third sieve holes 113. The plurality of first sieve holes 111 form a first screening area on the sieve plate 11, the plurality of second sieve holes 112 form a second screening area on the sieve plate 11, and the plurality of third sieve holes 113 form a third screening area on the sieve plate 11. The first screening area, the second screening area and the third screening area are arranged sequentially along the length direction of the sieve plate 11.

[0035] A partition 17 is provided between the first and second screening areas and between the second and third screening areas. The partition 17 divides the collection tank 12 into three sections. There are three drive units 15, which are respectively connected to the three collection tanks 12. Each collection tank 12 is provided with a corresponding collection port 121.

[0036] In this embodiment, different particle sizes of ceramic tile raw materials can be screened through the first sieve hole 111, the second sieve hole 112, and the third sieve hole 113. The particle size of the ceramic tile raw materials screened by the sieve plate 11 will gradually increase. During the process of vibration unit 2 providing vibration to the sieve plate 11, the ceramic tile raw materials will pass through the first sieve hole 111, the second sieve hole 112, and the third sieve hole 113 with gradually increasing sieve hole diameter in sequence, thereby performing three screenings, which can better screen and classify the ceramic tile raw materials.

[0037] On the other hand, by setting the partition 17, the screened ceramic tile raw materials can be prevented from mixing together and causing screening failure. Specifically, the partition 17 is set between the first screen hole 111 and the second screen hole 112 and between the second screen hole 112 and the third screen hole 113, and is divided into 3 collection chambers 3. Each collection chamber 3 has a drive unit 15, so that each collection chamber 3 can be cleaned.

[0038] Preferably, one end of the screening mechanism 1 is provided with a feed inlet 13, and the other end is a closed design.

[0039] With the above design, the raw materials for ceramic tiles fall from the feed inlet 13, are conveyed forward by the vibration unit 2, and are screened in sequence through the first screen hole 111, the second screen hole 112, and the third screen hole 113. Those that fail the screening will stay at the other end of the screening mechanism 1 for easy collection and processing by the staff.

[0040] Preferably, the screening mechanism 1 is further provided with a through groove 14, the upper part of the through groove 14 along its length direction is connected to the collection groove 12, and the collection port 121 is connected to the lower part of the through groove 14 along its length direction.

[0041] In the above design, during the screening process, the tile material falls onto the collection tank 12. Specifically, the collection tank 12 can be set to tilt towards the through channel 14, so that the tile material will gather in the direction of the through channel 14 and fall from the through channel 14 to the collection port 121, and finally be collected by the external collection device. On the other hand, during the operation of the drive unit 15, the lower cleaning unit 5 will clean the tile material to the through channel 14 and let it fall to the collection port 121, and finally be collected by the external collection device, thereby avoiding the waste of tile material due to its residue in the collection tank 12.

[0042] Preferably, the drive unit 15 includes a motor 151, a lead screw 154, a connecting rod 152, and a slider 153. The motor 151 is connected to the side of the screening mechanism 1. One end of the lead screw 154 is rotatably connected to one end of the collection trough 12. The other end of the lead screw 154 extends along the length of the collection trough 12 and passes through the collection trough 12 to connect with the motor 151. A sliding block is provided on the lead screw 154. The connecting rod 152 is symmetrically arranged on both sides of the sliding block. Slide rails 16 are provided on both sides of the collection trough 12. The slider 153 is slidably connected in the slide rails 16. The end of the connecting rod 152 is connected to the slider 153. The upper cleaning unit 4 and the lower cleaning unit 5 are respectively connected to the top and bottom of the movable block.

[0043] Through the above design, the motor 151 can drive the lead screw 154 to rotate, thereby causing the sliding block to move along the length direction of the lead screw 154. During this process, the sliding block can be restricted from rotating through the connecting rod 152, the slider 153, and the slide rail 16, so that the sliding block moves horizontally along the length direction of the lead screw 154, thereby driving the upper cleaning unit 4 and the lower cleaning unit 5 to move together. In this way, it can be ensured that the upper cleaning unit 4 and the lower cleaning unit 5 can clean the screen plate 11 and the collection tank 12 at the same time, thereby improving the cleaning effect.

[0044] Preferably, the vibration unit 2 includes a vibration motor 21 and a support block 23. The vibration motor 21 is connected to the support block 23. The support block 23 is connected to the bottom of the screening mechanism 1. The frame 6 is provided with a plurality of springs 22. The plurality of springs 22 are located at the top of the frame 6. The screening mechanism 1 is provided with a connecting block 18 corresponding to the plurality of springs 22 one by one. The springs 22 are connected to the connecting blocks 18.

[0045] In this embodiment, the vibration motor 21 provides vibration to the sieve plate 11. It should be noted that the sieve plate 11 in this embodiment is arranged at an angle downwards. Therefore, the screening mechanism 1 and the frame 6 are elastically connected by the spring 22, which allows the ceramic tile material to move along the direction of the sieve plate 11. Under the action of the vibration motor 21, the ceramic tile material will be screened and classified in sequence through the first sieve hole 111, the second sieve hole 112, and the third sieve hole 113.

[0046] Preferably, it also includes a guide plate 7, which is connected to the collection port 121, and the guide plate 7 is arranged at an angle downward.

[0047] With the above design, the tile material falling from the channel 14 to the collection port 121 will pass through the guide plate 7. With the guidance of the guide plate 7, it can fall into the external collection device and be collected. Specifically, the guide plate 7 can be designed to gradually narrow from the end near the collection port 121 to the end away from the collection port 121. This makes it easier for the tile material to fall in a concentrated manner and prevents it from falling outside the external collection device.

[0048] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
