Description

Technical Field

[0001] The invention relates to the technical field of material screening, and in particular to a highly airtight screening device for easily agglomerated materials. Background Art

[0002] Material screening is a key pretreatment process in material handling and processing, which is crucial to the quality of the product. In addition, material screening technology continues to innovate and develop in many aspects such as equipment structure, screen material, and automatic control, providing strong technical support for efficient and clean production in various industries. In order to protect the environment and the health of operators, reducing dust pollution during material screening has also become a key issue in the material screening process. Especially for materials that are easy to agglomerate, because they usually have a smaller particle size, they are easily lifted up by vibration and airflow during the screening process. In addition, these materials that are easy to agglomerate are prone to generate static electricity during the processing process, resulting in the particles adsorbing each other and not easily falling back to their original position during vibration, which also aggravates dust pollution.

[0003] However, the current equipment for screening materials that are easy to agglomerate usually uses an inflatable sealing ring to inflate and deflate at the docking position of the screening component and the discharging component to achieve a sealed docking of the upper and lower components. However, due to the wear of the inflatable sealing ring or the difference in the inflation pressure, displacement errors are easily generated when the upper and lower components are docked, that is, the docking surfaces of the two cannot be completely abutted and there is a gap, which in turn causes dust pollution and affects the health of operators. Therefore, it is of great significance to provide a screening device that can adapt to the displacement error generated during the docking process of the inflatable sealing ring to ensure the sealed docking of the upper and lower components for screening materials that are easy to agglomerate. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and to provide a highly airtight screening device for easily agglomerated materials.

[0005] The technical solution adopted by the present invention is as follows: a highly airtight screening device for easily agglomerated materials, comprising a screening component, a docking component and a discharging component, wherein a second material tray is arranged on the discharging component, the docking component is arranged between the screening component and the discharging component and comprises a mounting ring, an inflatable sealing ring and a docking plate, a first mounting block and a rotating joint are arranged on the outer wall of the upper end of the second material tray, a second movable groove is arranged in the first mounting block, the bottom of the rotating joint is abutted against the second movable groove, and a gap is arranged between the upper part of the rotating joint and the second movable groove, and the rotating joint is used to adapt to the displacement error of the docking; a docking block is arranged on the docking plate, a first movable groove adapted to the docking block is arranged in the rotating joint, and the docking plate and the first mounting block form a first sealing portion.

[0006] Through the above technical scheme, the cooperation between the docking block and the first movable groove is utilized to further improve the docking accuracy between the docking plate and the first mounting block, and provide basic guarantee for the airtightness of the docking point. If there is a difference in the inflation pressure of the inflatable sealing ring or aging occurs, resulting in inaccurate docking between the docking plate and the first mounting block, that is, the docking surfaces of the two cannot be completely abutted and there is a gap, the rotation of the rotating joint in the mounting block can effectively adapt to the displacement error in the above-mentioned docking process, ensuring that the docking plate and the first mounting block form an effective first sealing portion.

[0007] The present invention is further configured such that the docking block is wedge-shaped, and the docking block and the first movable groove form an inclined surface match.

[0008] Through the above technical solution, the docking block and the first movable groove adopt the inclined surface matching mode, thereby improving the guiding property between the two.

[0009] The present invention is further configured such that a second mounting block is provided on the inner wall of the upper end of the second material tray, a third movable groove is provided in the second mounting block, a sealing ring is provided in the third movable groove, a first protrusion is provided on the docking plate, the first protrusion is provided in the third movable groove and forms a second sealing portion with the sealing ring. The first protrusion abuts against one side of the sealing ring and a gap is provided on the other side, and the side where the first protrusion abuts against the sealing ring forms the second sealing portion.

[0010] Through the above technical solution, the first protrusion and the sealing ring form a dynamic seal, which further ensures the sealing after displacement error occurs during the docking process. If the docking plate and the first mounting block are worn after long-term use, causing the first sealing part to fail, the second sealing part can serve as a second sealing guarantee between the docking plate and the first mounting block.

[0011] The present invention is further configured such that a positioning protrusion is provided on the first protrusion, and a groove matched with the positioning protrusion is provided on the second mounting block.

[0012] Through the above technical solution, it is ensured that the first protrusion is accurately positioned in the third movable groove, and the second sealing portion is smoothly formed.

[0013] The present invention is further configured such that a guide surface is provided on the second mounting block, and the guide surface is inclined toward the inside of the second material tray.

[0014] The above technical solution prevents materials from falling into the second installation block and affecting the sealing effect.

[0015] The present invention is further configured such that the docking assembly also includes a feed port, the mounting ring is sleeved on the upper part of the feed port, the feed port is respectively connected to the screening assembly and the discharging assembly and the three are in communication, the inflatable sealing ring is arranged on the docking plate, the docking plate is slidably sleeved on the feed port, the upper end surface of the inflatable sealing ring and the mounting ring form a third sealing portion, and the docking plate and the first mounting block form the first sealing portion.

[0016] Through the above technical solution, the first sealing part, the second sealing part and the third sealing part are provided to realize the closed connection between the screening component and the discharging component.

[0035] like Figures 1 to 10 As shown, an embodiment of the present invention is provided:

[0036] A device for screening easily agglomerated materials comprises an outer frame 1, wherein a first support plate 101 and a second support plate 102 are arranged inside the outer frame 1, a feed turning assembly 2 is arranged on the first support plate 101, and the feed turning assembly 2 is sequentially connected with a buffer bucket 3, a screening assembly 4 and a discharging assembly 5 from top to bottom, the screening assembly 4 is arranged on the second support plate 102, and the lower end of the discharging assembly 5 is connected to the outer frame 1, and a lifting door assembly 6 is arranged on the outer frame 1 corresponding to the feed turning assembly 2 and the discharging assembly 5, so as to form a closed space at the feed and the discharging place.

The first cylinder 64 is provided with two and is symmetrically distributed on both sides of the closed door 61, and its driving rod is connected to the slider 63.

[0038] A docking assembly 7 is provided between the screening assembly 4 and the discharging assembly 5. The docking assembly 7 includes a mounting ring 71, an inflatable sealing ring 72, a feed port 73 and a docking plate 74. The mounting ring 71 is sleeved on the upper part of the feed port 73.
