Description

Technical Field

[0001] The utility model relates to the technical field of ore pulp detection, in particular to a material conveying device and an ore pulp ash analyzer. Background Art

[0002] Pulp ash refers to an instrument that uses X-ray fluorescence technology to establish a mathematical model suitable for different coal quality characteristics to detect the ash content of slurry online. In order to improve the accuracy of the test results, the slurry is usually filtered and compressed into a filter cake before testing.

[0003] The compressed filter cake is usually transported to the inspection station by the filter cloth for inspection. The step length of the filter cloth affects whether the filter cake can accurately reach the inspection station. Specifically, the two ends of the filter cloth are respectively wound on the unwinding roller and the receiving roller. When working, the receiving roller is driven to rotate by a motor or other driving parts to move and recycle the filter cloth.

[0004] The existing technology controls the step length of the filter cloth by controlling the start and stop of the receiving roller. However, as the number of filter cloths on the receiving roller increases, the outermost diameter of the filter cloth on the receiving roller is not a fixed value. The step length of the conveyor belt cannot be accurately controlled by simply controlling the start and stop of the receiving roller, resulting in the filter cake being unable to accurately reach the detection station, which in turn leads to low detection efficiency.

[0013] Furthermore, it also includes an elastic member for driving the first rotating roller to move toward the conveyor belt.

[0014] Furthermore, it also includes a clamping assembly for driving the first rotating roller to move away from or close to the conveyor belt.

[0018] Furthermore, it also includes an image detection mechanism, which is used to obtain the image of the material on the conveyor belt.

[0019] Furthermore, it also includes a cleaning component, which includes a first scraper abutting against the bearing surface of the conveyor belt.

DETAILED DESCRIPTION

[0032] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0034] It should be noted that in the description of the present invention, the terms "connection" and "installation" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through an intermediate medium; it can be a mechanical connection or an electrical connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The existing technology controls the step length of the conveyor belt by controlling the start and stop of the receiving roller. However, as there are more and more conveyor belts on the receiving roller, the outermost conveyor belt diameter of the receiving roller is not a fixed value. The step length of the conveyor belt cannot be accurately controlled by simply controlling the start and stop of the receiving roller, resulting in the material on the conveyor belt failing to accurately reach the set workstation.

[0036] In view of the above problems, an embodiment of the present application provides a material conveying device, referring to Figure 1 The material conveying device includes a conveyor belt 1, a discharge roller 2, a receiving roller 3, a first rotating roller 4 and an encoder 5;

[0037] The two ends of the conveyor belt 1 are respectively wound on the unwinding roller 2 and the receiving roller 3;

[0038] The first rotating roller 4 is arranged between the unwinding roller 2 and the receiving roller 3, and the outer peripheral surface of the first rotating roller 4 is in rolling contact with the conveyor belt 1;

[0039] The encoder 5 is connected to the first rotating roller 4 .

[0040] During the operation of the above device, the encoder 5 can collect information about the number of rotations of the first rotating roller 4. Since the diameter of the first rotating roller 4 is fixed, the moving length of the conveyor belt 1 can be accurately calculated by analyzing the information collected by the encoder 5, so that the step length of the conveyor belt 1 can be accurately controlled, so that the material can accurately reach the set position.

[0041] Continue to refer to Figure 1 The material conveying device also includes an image detection mechanism 9, which is used to obtain an image of the material on the conveyor belt 1.

[0042] In this embodiment, the image detection mechanism 9 includes a binocular camera suspended above the conveyor belt 1. Compared with an ordinary camera, a binocular camera can collect images at two different positions, and the image fusion collected by the two cameras can generate height information, thereby obtaining a relatively accurate material thickness signal, and the binocular camera has a higher resolution effect, which can improve the recognition accuracy of the material.

[0043] By identifying the image acquired by the image detection mechanism 9, it is possible to determine whether the surface of the material has defects such as bulges, pits, cracks, etc.; and the volume information of the material can also be obtained; in addition, the material can be positioned so that the material can accurately reach the next workstation.

[0044] The specific positioning method is: if the material position coordinates are all within the preset area, the material is transported to the next station; if the material position coordinates are partially or completely outside the preset area, the conveyor belt 1 is moved to drive the material to move until the material position coordinates are all within the preset area, and then the material is transported to the next station; if the material position coordinates cannot be moved to be completely within the preset area, the material is scrapped. The preset area is the shooting area of ​​the image detection mechanism 9, or a subset of the shooting area of ​​the image detection mechanism 9.

[0045] On the basis of the above structure, the material conveying device further includes an elastic member 7 for driving the first rotating roller 4 to move toward the conveyor belt 1 .

[0046] Optionally, the elastic member 7 is a compression spring, or a spring washer, or a tension spring, or a torsion spring. One end of the elastic member 7 is connected to a fixed structure (such as a frame), and the other end acts on the first rotating roller 4, thereby applying an elastic force to the first rotating roller 4 to move toward the conveyor belt 1.

[0047] In the above structure, the elastic member 7 can provide elastic force to drive the first rotating roller 4 to move toward the conveyor belt 1, so that the first rotating roller 4 and the conveyor belt 1 fit more closely, ensuring that the first rotating roller 4 can move synchronously with the conveyor belt 1, thereby improving the detection accuracy of the moving length of the conveyor belt 1.

[0048] Continue to refer to Figure 1 The material conveying device further comprises at least one second rotating roller 6, any one of which is arranged between the unwinding roller 2 and the receiving roller 3, and the outer peripheral surface of any one of which is in rolling contact with the conveyor belt 1. In this embodiment, the first rotating roller 4 is in contact with the bearing surface of the conveyor belt 1, and any one of which is in contact with the side of the conveyor belt 1 away from the bearing surface; the second rotating roller 6 plays a role in guiding and tightening the conveyor belt 1.

[0049] In other embodiments, the encoder 5 may also be connected to any second rotating roller 6 . This structure can also achieve the technical effect of detecting the moving length of the conveyor belt 1 .

[0050] Reference Figure 2 In this embodiment, the first rotating roller 4 is correspondingly arranged with a second rotating roller 6 and the conveyor belt 1 is clamped between the first rotating roller 4 and the corresponding second rotating roller 6. The above arrangement makes it difficult for the conveyor belt 1 clamped between the first rotating roller 4 and the corresponding second rotating roller 6 to shake, thereby further improving the detection accuracy of the moving length of the conveyor belt 1.

[0051] Furthermore, the material conveying device further comprises a clamping assembly 8 for driving the first rotating roller 4 to move away from or close to the conveyor belt 1 .

[0052] Specifically, the clamping assembly 8 includes a bracket 81 for fixing the first rotating roller 4, an adapter plate 82 slidably connected to the bracket 81, and a driving member 83 fixedly connected to the adapter plate 82;

[0053] The material conveying device further includes an elastic member 7 disposed between the bracket 81 and the adapter plate 82 .

[0054] In this embodiment, the driving member 83 is configured as a cylinder, which can push the first rotating roller 4 to move away from or close to the conveyor belt 1 through the adapter plate 82 and the bracket 81. Since the bracket 81 and the adapter plate 82 are slidably connected, and an elastic member 7 is provided between the two, the first rotating roller 4 can be adaptively floated and adjusted after contacting the conveyor belt 1, ensuring that the first rotating roller 4 can move synchronously with the conveyor belt 1.

[0055] Based on the above structure, the elastic member 7 is configured as a compression spring or a spring washer; the clamping assembly 8 also includes a guide rod 84, one end of which is fixedly connected to the bracket 81, and the other end of the guide rod 84 passes through the elastic member 7 and is slidably connected to the adapter plate 82.

[0056] Optionally, the number of the elastic members 7 can be set to one or more, and accordingly, the number of the guide rods 84 can also be set to one or more. Multiple elastic members 7 can make the first rotating roller 4 bear force evenly, can make the first rotating roller 4 and the conveyor belt 1 fit more closely, and can also ensure that the overall mechanism can be stretched and retracted smoothly without blocking problems.

[0057] Continue to refer to Figure 2 The first rotating roller 4 includes a roller shaft 41 and two contact wheels 42 sleeved on the roller shaft 41. The two contact wheels 42 are arranged at intervals and form a channel for the material to pass through. In this embodiment, the roller shaft 41 and the contact wheel 42 are integrally formed, which can simplify the processing and assembly process.

[0058] Furthermore, at least one groove is provided on the circumference of each contact wheel 42, and an elastic ring is provided in each groove. The elastic ring contacts the conveyor belt 1 to increase the friction between the first rotating roller 4 and the conveyor belt 1, and the elastic ring can be deformed without causing the problem of slipping during the transmission process.

[0059] In this embodiment, the encoder 5 is mounted on the bracket 81. Specifically, the encoder 5 is mounted on a plate member of the bracket 81, and the output shaft of the encoder 5 passes through the plate member and is connected to the first rotating roller 4 through a coupling.

[0060] Reference Figure 3 The material conveying device further comprises a cleaning assembly 10, and the cleaning assembly 10 comprises a first scraper 101 abutting against the bearing surface of the conveyor belt 1. The first scraper 101 is used to scrape off the material on the conveyor belt 1 to recycle the conveyor belt 1.

[0061] On the basis of the above structure, a recovery box is arranged below the first scraper 101, and the materials dropped from the conveyor belt 1 can fall into the recovery box, so that the materials can be recovered and the waste of materials can be avoided.

[0062] Reference Figure 4 The cleaning assembly 10 further includes a second scraper 102 disposed opposite to the first scraper 101 ; the conveyor belt 1 passes through a gap between the first scraper 101 and the second scraper 102 , and the first scraper 101 and the second scraper 102 are respectively in contact with two opposite sides of the conveyor belt 1 .

[0063] The first scraper 101 and the second scraper 102 can scrape both sides of the conveyor belt 1 to improve the cleaning effect of the conveyor belt 1 .

[0064] Another aspect of the present application is to provide a slurry ash analyzer, comprising a material conveying device according to any of the above embodiments.

[0065] In the slurry ash analyzer provided in the present application, the conveyor belt 1 can be made of filter cloth material.

[0066] Since the slurry ash analyzer provided in the present application adopts the material conveying device in the above-mentioned embodiment, the step length of the conveyor belt 1 can be accurately controlled, so that the material can accurately reach the set workstation, thereby improving the detection efficiency.

[0067] The slurry ash analyzer provided in the present application at least has the technical effects of the above-mentioned embodiments, which will not be described in detail here.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
