Description

Technical Field

[0001] The utility model belongs to the technical field of sagger processing. Specifically, it particularly relates to a screening device for processing sagger bottom materials. Background Technique

[0002] A sagger is one of the kiln furniture. During the process of firing ceramic wares, to prevent gases and harmful substances from damaging and soiling the green body and glaze surface, the ceramic wares and green body are placed in a container made of refractory materials for roasting. This container is called a sagger. During the production of saggers, in order to improve the overall quality of saggers, it is necessary to screen out the iron filings contained in the sagger bottom materials.

[0003] In the Chinese Patent Network CN214021363U, a special magnetic separator for sagger raw materials is disclosed, including a magnetic separator body. The magnetic separator body includes a mounting frame. A fixed seat is installed on the mounting frame. A first motor is installed on the fixed seat. An output shaft is installed on the first motor. A drum is installed at one end of the output shaft. Limit rings are installed at both ends of the drum. A feed hopper is installed on the mounting frame. A fixed frame is installed on one side of the feed hopper. A first electric push rod is installed on the fixed frame.

[0004] When screening the iron filings contained in the bottom materials, the bottom materials accumulate between the drum and the barrel under the block of the drum, so that the barrel adsorbs the iron filings in the bottom materials again. However, the accumulated bottom materials will block a part of the iron filings, making it difficult for the barrel to adsorb this part of the iron filings. Moreover, the setting of the drum makes it possible to put the bottom materials into the feed hopper again only after all the bottom materials between the drum and the barrel have fallen. Otherwise, it is easy to have the phenomenon that the bottom materials accumulated between the barrel and the drum become more and more, resulting in the inability of the whole device to perform continuous screening, thus reducing the screening efficiency of the whole device.

[0005] Regarding the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0006] Regarding the problems in the related technology, the utility model proposes a screening device for processing sagger bottom materials to overcome the above-mentioned technical problems existing in the existing related technology.

[0007] To solve the above-mentioned technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model relates to a screening device for processing the bottom material of a sagger, which comprises a screening box. A transportation component is arranged inside the screening box, and an adsorption component is arranged on the outer surface of the transportation component. A leveling component is fixedly installed on the top of the screening box. The leveling component can level the materials on the transportation component step by step. A scraping component is fixedly installed on the inner wall of the screening box, and the scraping end of the scraping component is in contact with the lower surface of the transportation component.

[0009] Further, the transportation component comprises a rotating roller, the rotating roller is rotationally connected with the screening box, a transportation belt is arranged on the outer surface of the rotating roller, a motor is fixedly installed on the back of the screening box, and the output end of the motor is fixedly connected with the rotating roller.

[0010] Further, the adsorption component comprises a flexible magnetic tape. A plurality of installation grooves are arranged in a row on the outer surface of the transportation belt, and the flexible magnetic tape is arranged inside the installation grooves.

[0011] Further, the leveling component comprises a T-shaped fixing plate. The T-shaped fixing plate is fixedly installed on the top of the inner wall of the screening box. A plurality of T-shaped fixing plates are arranged in a row inside the screening box. A leveling rod is fixedly connected to the bottom of the T-shaped fixing plate. The leveling rods at the bottoms of the plurality of T-shaped fixing plates are arranged in a row with the spacing gradually decreasing along the rotation direction of the transportation belt.

[0012] Further, the scraping component comprises a scraping plate. The scraping plate is obliquely installed on the inner wall of the screening box. The top end of the scraping plate is in contact with the transportation belt. An electromagnetic plate is fixedly installed on the inner wall of the screening box, and the electromagnetic plate is perpendicular to the scraping plate.

[0013] Further, a feeding groove is opened at the top of the screening box, a bottom material discharging groove is opened at the bottom of the screening box, and an iron filings discharging groove is opened at the bottom of the screening box. The feeding groove and the bottom material discharging groove are arranged diagonally. A plurality of hoppers are arranged on the outer surface of the screening box corresponding to the feeding groove, the bottom material discharging groove and the iron filings discharging groove.

[0014] Further, a first baffle is fixedly installed at the bottom of the feeding groove, and a second baffle is fixedly connected between the bottom material discharging groove and the iron filings discharging groove.

[0015] Further, an observation groove is opened on the front surface of the screening box corresponding to the electromagnetic plate, and glass is fixedly connected inside the observation groove.

[0016] The utility model has the following beneficial effects:

[0017] 1. In the utility model, the base material can move inside the screening box through the transportation component. At this time, under the step-by-step leveling of the leveling component, the base material can be evenly spread on the top of the transportation component, so that the adsorption component can better adsorb iron filings. When the transportation component drives the base material to move to the turning position, the base material can automatically fall off. As the transportation component continues to move, the scraping component can scrape off the iron filings adsorbed by the adsorption component, so that the base material and the iron filings can be separated by screening. To sum up, under the drive of the transportation component, the base material is not easy to accumulate. At the same time, with the assistance of the leveling component, the adsorption component can better adsorb the iron filings inside the base material, so that the device can continuously carry out screening operations, and the screening effect can be guaranteed.

[0018] 2. When the iron filings adsorbed by the flexible tape in the utility model move to the scraper, the scraper scrapes the iron filings adsorbed on the flexible tape. At this time, the electromagnetic plate is in an energized state, and the overall magnetism of the electromagnetic plate is stronger than that of the flexible tape, so that the electromagnetic plate can adsorb the iron filings blocked by the scraper, so that the iron filings will not accumulate at the position where the scraper contacts the conveyor belt. When too many iron filings are adsorbed on the electromagnetic plate, the electromagnetic plate is directly powered off. At this time, the electromagnetic plate no longer has magnetism. Coupled with the inclined setting of the electromagnetic plate, the iron filings on the electromagnetic plate can directly roll off the electromagnetic plate. With the cooperation of the scraper and the electromagnetic plate, the effect of cleaning the iron filings adsorbed by the flexible tape is better, so that the flexible tape can better adsorb the iron filings inside the subsequent base material.

[0019] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0031] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the utility model.

[0032] Please refer to Figures 1 - 7 As shown, the present utility model is a screening device for processing the bottom material of a sagger, including a screening box 1. A transportation component 2 is arranged inside the screening box 1. An adsorption component 3 is arranged on the outer surface of the transportation component 2. A leveling component 4 is fixedly installed on the top of the screening box 1. The leveling component 4 can level the materials on the transportation component 2 step by step. A scraping component 5 is fixedly installed on the inner wall of the screening box 1. The scraping end of the scraping component 5 is in contact with the lower surface of the transportation component 2.

[0033] By putting the base material into the interior of the screening box 1, at this time the base material directly falls onto the top of the transport component 2 and moves to the other side of the screening box 1 under the drive of the transport component 2. During the movement, the leveling component 4 can gradually level the base material on the transport component 2, so that the adsorption component 3 arranged on the transport component 2 can better adsorb the iron filings inside the base material. When the base material moves to the turning position of the transport component 2 driven by the transport component 2, the base material can automatically break away from the transport component 2 under the influence of its own gravity. At this time, the iron filings continue to move with the transport component 2 under the adsorption of the adsorption component 3. When the iron filings move to the scraping component 5, the scraping component 5 can scrape the iron filings on the adsorption component 3 off.

[0034] Through the transport component 2, the base material can move inside the screening box 1. At this time, under the gradual leveling of the leveling component 4, the base material can be evenly spread on the top of the transport component 2, so that the adsorption component 3 can better adsorb the iron filings. When the transport component 2 drives the base material to move to the turning position, the base material can automatically fall off. As the transport component 2 continues to move, the scraping component 5 can scrape off the iron filings adsorbed by the adsorption component 3, so that the base material and the iron filings can be separated by screening. To sum up, under the drive of the transport component 2, the base material is not prone to accumulation. At the same time, with the assistance of the leveling component 4, the adsorption component 3 can better adsorb the iron filings inside the base material, so that the device can continuously carry out screening operations and the screening effect can be guaranteed.

[0035] In one embodiment, for the above-mentioned transport component 2, the transport component 2 includes a rotating roller 201, the rotating roller 201 is rotatably connected to the screening box 1, a transport belt 202 is arranged on the outer surface of the rotating roller 201, and a motor 203 is fixedly installed on the back of the screening box 1. The output end of the motor 203 is fixedly connected to the rotating roller 201.

[0036] The motor 203 can drive the transport belt 202 to rotate inside the screening box 1 through the rotating roller 201. The setting of the transport belt 202 enables the transport belt 202 to support the base material and drive it to move, so that the leveling component 4 can better level the base material. When the transport belt no longer supports the base material, the base material can automatically fall off the transport belt 202. And because the transport belt 202 is constantly rotating, the base material is not prone to accumulation on the transport belt 202.

[0037] In one embodiment, for the above-mentioned adsorption component 3, the adsorption component 3 includes a flexible magnetic tape 301. A plurality of mounting grooves 302 are arranged in a row on the outer surface of the transport belt 202, and the flexible magnetic tape 301 is arranged inside the mounting grooves 302.

[0038] The flexible magnetic tape 301 can adsorb iron filings. When the conveyor belt 202 no longer supports the base material, the base material drops, while the iron filings can continue to move with the conveyor belt 202 under the transportation of the flexible magnetic tape 301, so that the iron filings and the base material can be separated.

[0039] In one embodiment, for the above-mentioned leveling assembly 4, the leveling assembly 4 includes a T-shaped fixing plate 401, the T-shaped fixing plate 401 is fixedly installed at the top of the inner wall of the screening box 1, and a plurality of the T-shaped fixing plates 401 are arranged in an array inside the screening box 1. A rake rod 402 is fixedly connected to the bottom of the T-shaped fixing plate 401, and the rake rods 402 at the bottoms of the plurality of T-shaped fixing plates 401 are arranged in an array with gradually decreasing spacing along the direction of rotation of the conveyor belt 202.

[0040] When the conveyor belt 202 drives the base material to move past the bottom of the T-shaped fixing plate 401, the rake rod 402 can level the base material. Coupled with the fact that the spacing between the rake rods 402 at the bottoms of the plurality of T-shaped fixing plates 401 along the moving direction of the conveyor belt 202 is getting smaller and smaller, and the distance between the bottom of the T-shaped fixing plate 401 and the top of the conveyor belt 202 is also getting smaller and smaller, so that after the base material on the conveyor belt 202 is evenly spread on the top of the conveyor belt 202, the overall base material is getting thinner and thinner. This setting enables the flexible magnetic tape 301 to better adsorb iron filings.

[0041] In one embodiment, for the above-mentioned scraping assembly 5, the scraping assembly 5 includes a scraper 501, the scraper 501 is obliquely installed on the inner wall of the screening box 1, the top end of the scraper 501 is in contact with the conveyor belt 202, and an electromagnetic plate 502 is fixedly installed on the inner wall of the screening box 1, and the electromagnetic plate 502 is perpendicular to the scraper 501.

[0042] When the iron filings adsorbed by the flexible magnetic tape 301 move to the scraper 501, the scraper 501 scrapes the iron filings adsorbed on the flexible magnetic tape 301. At this time, the electromagnetic plate 502 is in an energized state, and the overall magnetism of the electromagnetic plate 502 is stronger than that of the flexible magnetic tape, so that the electromagnetic plate 502 can adsorb the iron filings blocked by the scraper 501, so that the iron filings will not accumulate at the position where the scraper 501 contacts the conveyor belt 202. When there are too many iron filings adsorbed on the electromagnetic plate 502, the electromagnetic plate 502 is directly powered off. At this time, the electromagnetic plate 502 no longer has magnetism. Coupled with the fact that the electromagnetic plate 502 is obliquely arranged, the iron filings on the electromagnetic plate 502 can directly roll down from the electromagnetic plate 502. The cooperation between the scraper 501 and the electromagnetic plate 502 makes the effect of cleaning the iron filings adsorbed by the flexible magnetic tape 301 better, so that the flexible magnetic tape 301 can better adsorb the iron filings inside the subsequent base material.

[0043] In one embodiment, for the above-mentioned screening box 1, a feed chute 6 is provided at the top of the screening box 1, a bottom material discharge chute 7 is provided at the bottom of the screening box 1, and an iron filings discharge chute 8 is provided at the bottom of the screening box 1. The feed chute 6 and the bottom material discharge chute 7 are arranged diagonally. A plurality of hoppers 9 are provided on the outer surface of the screening box 1 corresponding to the feed chute 6, the bottom material discharge chute 7, and the iron filings discharge chute 8.

[0044] The bottom material is put onto the top of the conveyor belt 202 through the hopper 9 provided on the feed chute 6. At the same time, when the conveyor belt 202 no longer supports the bottom material, the dropped bottom material can directly fall into the interior of the bottom material discharge chute 7 and fall from the interior of the screening box 1 through the corresponding hopper 9. The iron filings cleaned by the scraper 501 and the electromagnetic plate 502 can directly fall into the interior of the iron filings discharge chute 8 and fall from the interior of the screening box 1 through the corresponding hopper 9. The settings of the bottom material discharge chute 7 and the iron filings discharge chute 8 enable the bottom material and the iron filings to be collected separately after screening.

[0045] In one embodiment, for the above-mentioned feed chute 6, a first baffle 10 is fixedly installed at the bottom of the feed chute 6, and a second baffle 11 is fixedly connected between the bottom material discharge chute 7 and the iron filings discharge chute 8.

[0046] Since the position where the feed chute 6 turns with the conveyor belt 202 is relatively close, the first baffle 10 can block the bottom material falling from the feed chute 6, so that the bottom material will not fall from the turning position of the conveyor belt 202. Thus, the bottom material can only be separated from the conveyor belt 202 after passing through the leveling assembly 4 under the drive of the conveyor belt 202. The setting of the second baffle 11 enables the bottom material and the iron filings to accurately fall into the corresponding discharge chutes, and will not be mixed again under the shielding of the second baffle 11 during the dropping process.

[0047] In one embodiment, for the above-mentioned screening box 1, an observation slot 12 is provided on the front surface of the screening box 1 corresponding to the electromagnetic plate 502, and a glass 13 is fixedly connected inside the observation slot 12.

[0048] The adsorption situation of the iron filings on the electromagnetic plate 502 can be viewed through the glass 13 and the observation slot 12, so that the operator can clean the iron filings adsorbed on the electromagnetic plate 502 in a relatively timely manner.

[0049] In summary, by means of the above technical solution of the present utility model, the base material is put onto the top of the conveyor belt 202 through the hopper 9 provided on the feed chute 6. The conveyor belt 202 rotates driven by the motor 203 and the roller 201 and drives the base material to move inside the screening box 1. When the conveyor belt 202 drives the base material to move past the bottom of the T-shaped fixing plate 401, the rake rod 402 can level the base material, and the more T-shaped fixing plates 401 the base material passes through, the thinner the overall base material becomes. During this period, the flexible magnetic tape 301 can adsorb the iron filings inside the base material. When the conveyor belt 202 no longer supports the base material, the base material drops and moves out of the screening box 1 through the base material discharge chute 7, while the iron filings can continue to move with the conveyor belt 202 under the transportation of the flexible magnetic tape 301. When the iron filings adsorbed by the flexible magnetic tape 301 move to the scraper 501, the scraper 501 scrapes the iron filings adsorbed on the flexible magnetic tape 301. At this time, the electromagnetic plate 502 can adsorb the iron filings blocked by the scraper 501. When there are too many iron filings adsorbed on the electromagnetic plate 502, the electromagnetic plate 502 is directly powered off. At this time, the electromagnetic plate 502 no longer has magnetism, and the iron filings on the electromagnetic plate 502 can directly roll down from the electromagnetic plate 502 under the guidance of the electromagnetic plate 502 and move out of the screening box 1 through the iron filing discharge chute 8.

[0050] Through the above technical solutions: 1. The base material can move inside the screening box 1 through the transportation component 2. At this time, under the step-by-step leveling of the leveling component 4, the base material can be evenly spread on the top of the transportation component 2, so that the adsorption component 3 can better adsorb iron filings. When the transportation component 2 drives the base material to move to the turning position, the base material can automatically fall off. As the transportation component 2 continues to move, the scraping component 5 can scrape off the iron filings adsorbed by the adsorption component 3, so that the base material and the iron filings can be screened out. To sum up, under the drive of the transportation component 2, the base material is not prone to accumulation. At the same time, with the assistance of the leveling component 4, the adsorption component 3 can better adsorb the iron filings inside the base material, so that the device can continuously perform screening operations and the screening effect can be guaranteed; 2. When the iron filings adsorbed by the flexible magnetic tape 301 move to the scraper 501, the scraper 501 scrapes off the iron filings adsorbed on the flexible magnetic tape 301. At this time, the electromagnetic plate 502 is in an energized state, and the overall magnetism of the electromagnetic plate 502 is stronger than that of the flexible magnetic tape, so that the electromagnetic plate 502 can adsorb the iron filings blocked by the scraper 501, so that the iron filings will not accumulate at the position where the scraper 501 contacts the conveyor belt 202. When too many iron filings are adsorbed on the electromagnetic plate 502, the electromagnetic plate 502 is directly powered off. At this time, the electromagnetic plate 502 no longer has magnetism. Coupled with the inclined setting of the electromagnetic plate 502, the iron filings on the electromagnetic plate 502 can directly roll off the electromagnetic plate 502. The cooperation of the scraper 501 and the electromagnetic plate 502 results in a better effect when cleaning the iron filings adsorbed by the flexible magnetic tape 301, so that the flexible magnetic tape 301 can better adsorb the iron filings inside the subsequent base material.
