[0003] The heavy load large inclination belt conveyor in the steelmaking plant generally designs the conveying belt body as a bucket-shaped structure because of the large arrangement angle of the conveying belt body and the need to convey relatively loose materials, and the apron (corrugated baffle), horizontal baffle and base belt form a bucket-shaped container for conveying materials.

[0004] During the use of the heavy load large inclination belt conveyor in the steelmaking plant, a layer of material will gradually accumulate on the conveying belt body (belt) ; when conveying dry materials, a layer of dry powder and debris will accumulate on the conveying belt body; when conveying materials with high moisture content (such as wet coke, wet clay, etc.), a layer of wet mud will accumulate on the conveying belt body; these materials need to be cleaned regularly to reduce energy consumption, reduce wear of the conveying belt body and reduce the probability of safety risks such as slippage of the conveying belt body;

[0005] In the prior art, the conveying belt body without apron and horizontal baffle is generally provided with a brush and / or dust suction assembly close to the base belt to clean floating dust, and a scraper to remove the mud layer; but for the conveying belt body with apron and horizontal baffle, due to the existence of the apron and horizontal baffle, there are a large number of corners, gaps and obstacles on the conveying belt body, and it is difficult to adapt and meet the cleaning requirements by simply using a brush, dust suction assembly and scraper, especially the position close to the apron and the position close to the horizontal baffle are difficult to clean thoroughly, and manual cleaning is required, which is difficult, labor-intensive and dangerous, and is not conducive to efficient cleaning.

[0006] Therefore, there is a need for a belt conveyor with self-cleaning function which is convenient and efficient in cleaning process and can clean the powdery and muddy materials accumulated on the conveying belt body. SUMMARY

[0007] The belt conveyor with self-cleaning function provided by the embodiment of the present application solves the technical problem of the belt conveyor with apron and horizontal baffle in the prior art, which is difficult to clean, has high risk, is labor-intensive and difficult to clean automatically and conveniently and efficiently due to the limitation of its own structure, and achieves the technical effect that the belt conveyor with apron and horizontal baffle can be automatically cleaned, the cleaning process is convenient and efficient, and powdery and muddy materials accumulated on the conveying belt body can be cleaned thoroughly.

DETAILED DESCRIPTION

[0057] In order to facilitate the understanding of the present application, the present application will be described in more detail below with reference to the relevant drawings; the preferred embodiments of the present application are shown in the drawings, but the present application can be realized in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0058] It should be noted that the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only embodiment.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs; the terms used herein in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0060] Example 1

[0061] As Figures 1 to 6 shown, the belt conveyor with self-cleaning function of the application comprises a conveying belt body, a roller 004, a carrier 005, a material receiving container 007, a sliding cleaning assembly, a power assembly and a control unit.

[0062] The conveying belt body comprises a base belt 001, a skirt 002 and a transverse partition plate 003.

[0063] The base belt 001 is an annular belt body.

[0064] The skirt 002 is approximately wave-shaped in appearance and is made of rubber or elastic material, is positioned at the outer ring of the base belt 001 near the edge, and is tightly attached to the base belt 001; the skirt 002 is annular in whole and the number is two, which are arranged near the two edges of the base belt 001.

[0065] The transverse partition plate 003 is a hard or rubber plate body, is arranged transversely, has the same width direction as the base belt 001, has a length of more than 0.8 times the distance between the two skirts 002, is fixed on the base belt 001 and arranged tightly against the outer ring of the base belt 001, the number is multiple, and the distance between them is less than 1 meter; the transverse partition plate 003, the skirt 002 and the base belt 001 form multiple bucket-shaped containers together.

[0066] The roller 004 is arranged tightly against the inner ring of the base belt 001, comprises a driving roller, a driven roller and a supporting roller, and is used to maintain the straight state of the conveying belt body and drive the conveying belt body to move;

[0067] The carrier 005 is positioned on the ground and is a hard frame body, which plays a role of supporting and bearing the roller 004.

[0068] The power assembly is used to provide power for the operation of each component of the belt conveyor with self-cleaning function of the application, and the control unit plays a role of controlling the coordinated operation of each component of the belt conveyor with self-cleaning function, which are both prior art and will not be described here.

[0069] The conveying belt body, the roller 004, the carrier 005, the power assembly and the control unit are all prior art and will not be described here.

[0070] The two skirts 002 are the same in structure, and the combination of the two skirts 002 is double wave line-shaped.

[0071] The material receiving container 007 is a box-shaped container, has an upward opening, is placed at the bottom of the base belt 001, and is used to receive the falling material.

[0072] One or more proximity switches are located near the edge of the base belt 001. These proximity switches are signal-connected to the control unit and provide data support for the control unit to determine the posture of the conveyor belt. When the proximity switch approaches or reaches a specific position, it changes its on / off state and notifies the control unit (the specific position is located on the carrier 005, the receiving container 007, or the sliding cleaning assembly, and is manually set during manufacturing). The control unit determines the specific spatial position of each component of the conveyor belt at that time point based on the timing of the proximity switch changing its on / off state. The control unit uses the data obtained from the proximity switches to determine the precise position of the skirt 002 and the crossbar 003 relative to the sliding cleaning assembly, thereby facilitating the timely deformation of the sliding cleaning assembly to ensure the smooth progress of the cleaning operation. The proximity switches are existing technology.

[0073] The sliding cleaning assembly is located at the bottom of the base belt 001 and at the top of the receiving container 007, and is used to remove and sweep away the material accumulated on the conveyor belt.

[0074] like Figure 5 , Figure 6 and Figure 7 As shown, the sliding cleaning assembly includes a base frame 110, a sliding block, a scraping cleaning assembly 140, and a sweeping cleaning assembly 150;

[0075] The base frame 110 is a rigid frame that is fixed to the ground and located on top of the receiving container 007. Its length direction is perpendicular to the width direction of the base belt 001.

[0076] The sliding block includes a vertical sliding block 130;

[0077] The vertical sliding block 130 is a vertically placed rigid rectangular block, positioned on the top of the base frame 110, and is used to support and position the scraping cleaning component 140 and the sweeping cleaning component 150.

[0078] The vertical sliding block 130 moves laterally along the width direction of the conveyor belt under the coordinated control of the control unit and the power component;

[0079] The scraping and cleaning component 140 is used to remove wet materials adhering to the conveyor belt, and the sweeping and cleaning component 150 is used to sweep away dry materials adhering to the conveyor belt.

[0080] The scraping and cleaning assembly 140 includes a support belt assembly and a cleaning belt body 146;

[0081] The support belt assembly is positioned on one side of the vertical sliding block 130 and is raised and lowered in a controlled manner. It is used to support and support the cleaning belt 146 into a rounded rectangular shape and drive the cleaning belt 146 to rotate, thereby facilitating the cleaning process.

[0082] The supporting belt assembly comprises a center carrier 141, an insertion column 143, a floating carrier plate 144, and a supporting belt wheel 145.

[0083] The center carrier 141 is a rectangular hard block, the length direction of which is the same as the width direction of the base belt 001, and the width direction is perpendicular to the horizontal ground.

[0084] The center carrier 141 of the scraping and cleaning assembly 140 is located on one side of the vertical sliding block 130 and is transversely arranged. Both ends are provided with at least two insertion holes 142 matched with the insertion column 143. The center carrier 141 is lifted along the vertical sliding block 130 under the coordinated control of the control unit and the power assembly.

[0085] As shown in Figure 8 The insertion column 143 is a transversely arranged hard column body, which is inserted into the insertion hole 142 one by one. The insertion hole 142 is internally provided with a compression spring. One end of the compression spring abuts against the hole bottom of the insertion hole 142, and the other end abuts against the end portion of the insertion column 143. The compression spring is contracted under pressure and plays a buffering role.

[0086] The floating carrier plate 144 is a hard plate body, and the number of the floating carrier plate 144 is two. The length direction and the width direction of the floating carrier plate 144 are the same as the length direction and the width direction of the center carrier 141, respectively. The floating carrier plate 144 is located on both sides of the center carrier 141 and is fixed at the end portion of the insertion column 143. The floating carrier plate 144 moves with the movement of the insertion column 143.

[0087] The supporting belt wheel 145 is a hard wheel body, and the number of the supporting belt wheel 145 is four. The supporting belt wheel 145 is rotationally connected to the floating carrier plate 144, and at least one of the supporting belt wheels 145 rotates under the coordinated control of the control unit and the power assembly. The axial direction of the supporting belt wheel 145 is parallel to the horizontal ground.

[0088] The four supporting belt wheels 145 are respectively located at the four corners of the combination of the center carrier 141, the insertion column 143, and the floating carrier plate 144.

[0089] The cleaning belt body 146 is an annular belt body, which is sleeved on the four supporting belt wheels 145 and is always in a straightened state. The cleaning belt body 146 is a circular-rectangular annular belt body, which surrounds the combination of the center carrier 141, the insertion column 143, and the floating carrier plate 144.

[0090] The outer ring of the cleaning belt body 146 is fixed with a row of cleaning scrapers 148. The cleaning scraper 148 is a plastic or metal scraper, which is in a sheet shape. The included angle between the cleaning scraper 148 and the cleaning belt body 146 is less than 80 degrees. The position close to the cleaning belt body 146 is thicker, and the longitudinal section is triangular. The cleaning belt body 146 rotates to scrape and clean the wet materials adhered to the conveyor belt body.

[0091] As shown in Figure 6 and Figure 9As shown, the structure of the sweeping and cleaning component 150 is basically the same as that of the scraping and cleaning component 140. The difference is that its supporting belt component is located on the other side of the vertical sliding block 130, and there is no cleaning scraper 148 on the outer ring of its cleaning belt body 146, but it is densely covered with bristles 151.

[0092] Furthermore, a ring-shaped rib is provided on the inner ring of the cleaning belt body 146, and a ring-shaped groove adapted to the ring-shaped rib is provided on the supporting belt wheel 145; the presence of the ring-shaped rib and the ring-shaped groove makes it difficult for the cleaning belt body 146 to disengage from the supporting belt wheel 145.

[0093] Furthermore, the cross-section of the cleaning belt body 146 is in a C shape, a U shape or a C shape.

[0094] During the cleaning process, at the same time, the scraping and cleaning component 140 and the sweeping and cleaning component 150 are at different heights, and only one of them抵触着输送带体,另一不与输送带体相接触;不进行清理时,刮除清理组件140和扫除清理组件150均处于低位,不与输送带体相接触。

[0095] When the belt conveyor with self-cleaning function in the embodiment of the present application is in use:

[0096] When dealing with dry and wet sticky materials, different parts of the sliding cleaning component are used and selected according to needs.

[0097] When dry sticky materials need to be processed:

[0098] The control unit适时控制扫除清理组件150上移塞入裙边002之间,使得刷毛151同时抵触输送带体的基带001与两个裙边002(此时扫除清理组件150的两端分别抵触着其中一个裙边002的凸起与另一个裙边002的凹陷);

[0099] 控制扫除清理组件150的清理带体146转动,利用刷毛151对基带001和裙边002进行刷洗清理;

[0100] 随着输送带体的移动,控制立滑移块130沿着滑移载块120往复横移,使得刷毛151始终抵触着两个裙边002;

[0101] 在扫除清理组件150的清理带体146即将碰撞横隔板003时,控制扫除清理组件150下移避开横隔板003而后控制扫除清理组件150上移继续对输送带体进行清理。

[0102] When wet sticky materials need to be processed:

[0103] It should be noted that there is an unclear expression "抵触着输送带体,另一不与输送带体相接触" in the original text, which needs to be further clarified to ensure the accuracy of the translation.The control unit controls the scraping cleaning assembly 140 to move up and insert between the skirt edges 002 according to the data provided by the proximity switch, so that the cleaning scraper 148 simultaneously contacts the base belt 001 and the two skirt edges 002 of the conveyor belt body;

[0104] The control unit controls the rotation of the cleaning belt body 146 of the scraping cleaning assembly 140 to use the cleaning scraper 148 to shovel and clean the wet material on the base belt 001 and the skirt edges 002;

[0105] With the movement of the conveyor belt body, the control unit controls the horizontal movement of the vertical sliding block 130 along the sliding carrier 120, so that the cleaning scraper 148 always contacts the two skirt edges 002;

[0106] When the cleaning belt body 146 of the scraping cleaning assembly 140 is about to collide with the transverse partition plate 003, the control unit controls the scraping cleaning assembly 140 to move down to avoid the transverse partition plate 003, and then controls the scraping cleaning assembly 140 to move up to continue cleaning the conveyor belt body.

[0107] Further, as shown in Figure 2 The belt conveyor with the self-cleaning function further includes a cover 006. The cover 006 is a hard shell that covers part of the base belt 001, the roller 004, and the carrier 005, and plays a role of bearing and supporting the feeding hopper and avoiding the exposure of the moving parts of the belt conveyor to the outside, thereby reducing the use risk of the belt conveyor.

[0108] Further, one side of the cover 006 is provided with an access opening, and a guardrail and a support for bearing the guardrail are arranged on the access opening. The guardrail is detachably positioned on the support and has a vertically arranged rod body at the bottom. One side or the inside of the receiving container 007 is provided with a positioning body matched with the bottom of the guardrail, and the positioning body is a vertically arranged hard pipe body. When the receiving container 007 needs to be emptied, the guardrail can be detached and inserted into the positioning body of the receiving container 007, and then the receiving container 007 can be conveniently pulled out.

[0109] The technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0110] The technical problems of the belt conveyor with skirt edges and transverse partition plates in the prior art, such as high difficulty in cleaning, high risk, high labor intensity, and difficulty in convenient and efficient automatic cleaning, are solved, and the belt conveyor with skirt edges and transverse partition plates can be automatically cleaned, the cleaning process is convenient and efficient, and the powdery and muddy materials accumulated on the conveyor belt body can be thoroughly cleaned.

[0111] Embodiment 2

[0112] In order to further improve the cleaning effect of the sliding cleaning assembly on the conveying belt body, and further improve the practicability of the belt conveyor with the self-cleaning function, the structure of the transverse partition plate 003 and the structure of the sliding cleaning assembly are optimized and improved based on the above embodiment, so that the sliding cleaning assembly does not need to control the descending of the scraping cleaning assembly 140 and the sweeping cleaning assembly 150 when it needs to avoid the transverse partition plate 003, thereby overcoming the problem that the part of the conveying belt body close to the end of the transverse partition plate 003 cannot be cleaned in place, and the specific improvements are as follows:

[0113] As shown in Figure 10 , the distance between the end of the transverse partition plate 003 and the skirt 002 is more than twice the diameter of the belt supporting wheel 145; the end of the transverse partition plate 003 is sharp; the height of the transverse partition plate 003 is less than 5 cm, and the longitudinal section is triangular;

[0114] Under normal circumstances, the distance between the top of the cleaning belt 146 of the scraping cleaning assembly 140 and the sweeping cleaning assembly 150 and the top of the center carrier 141 is greater than 5 cm;

[0115] The cleaning belt 146 is a ferromagnetic metal ring-shaped soft belt, or a soft belt body with a large number of adsorption bodies on the surface; the adsorption body is an iron sheet or an iron strip, arranged in one row or multiple rows;

[0116] The top of the center carrier 141 (the center carrier 141 of the scraping cleaning assembly 140 and the sweeping cleaning assembly 150) is positioned with an adsorption magnet 161; the adsorption magnet 161 is a strip-shaped electromagnet controlled by the control unit to be turned on and off, and generates a magnetic force to attract the cleaning belt 146 when powered on, so that the position close to the top of the cleaning belt 146 is bent and deformed (the cleaning belt 146 is shaped by adsorption; when the deformation occurs, the insertion column 143 is pressed to slide a certain distance); the adsorption magnet 161 is powered on when the cleaning belt 146 is close to the transverse partition plate 003, thereby avoiding the transverse partition plate 003 and still being able to clean the position close to the end of the transverse partition plate 003.
