Description

Technical Field

[0001] The utility model relates to the technical field of material detection, in particular to a vertical detection device. Background Art

[0002] In the field of coal identification and sorting, materials are typically laid out flat on a uniformly moving belt or identified while sliding in a chute. Chute identification methods require less space and are more convenient to deploy than belt-based methods. However, when the material is wet, fine particles can easily form a solid mass within the chute, affecting the identification process. Furthermore, inconsistent sliding speeds and changes in the material's posture within the chute can also affect identification accuracy. Utility Model Content

[0003] The main purpose of the utility model is to provide a vertical detection device to solve the problem that in the chute identification method, when the material is wetted, fine particles are easily agglomerated in the chute and stuck in the middle of the identification channel, affecting the identification process, and the problem that the inconsistent sliding speed and posture changes of the material in the chute also affect the identification accuracy.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a vertical detection device, including a ray generating part, a ray receiving part and a detection channel. The detection channel is arranged between the ray generating part and the ray receiving part. A ray component is provided in the ray generating part, and a linear array component is provided in the ray receiving part for receiving X-rays emitted by the ray component; the detection channel is perpendicular to the X-rays emitted by the ray component.

[0005] Furthermore, the radiation assembly includes a radiation shielding chamber to prevent X-ray leakage. The radiation source is arranged in the radiation shielding chamber. A collimator is provided along the direction of the radiation source beam. The radiation shielding chamber has a slit along the X-ray direction. The two ends of the collimator are connected to the radiation source and the slit.

[0006] Furthermore, long holes are opened on both sides of the detection channel, and the long holes are arranged horizontally with the slit. X-rays are emitted from the slit and enter the detection channel through the long holes.

[0007] Furthermore, the elongated holes are covered with a carbon fiber plate.

[0008] Furthermore, a baffle is provided above the elongated hole, and one end of the baffle is fixedly connected to the inner wall of the detection channel.

[0009] Furthermore, one end of the baffle is fixedly connected to the inner wall of the detection channel, and the other end is bent into the detection channel.

[0010] Furthermore, a feed port is provided on the detection channel, the feed port is located above the long strip hole, and a lead curtain is provided on the feed port.

[0011] Furthermore, the feed port is arranged on the side of the detection channel, and the lead curtain is arranged in a ring shape to cover the entire feed port.

[0012] Furthermore, the housings of the ray generating unit and the ray receiving unit are made of a lead-containing material.

[0013] Furthermore, both the ray generating unit and the ray receiving unit are provided with inspection doors.

[0014] The technical solution of the present invention includes a ray generator, a ray receiver, and a detection channel. The detection channel is arranged between the ray generator and the ray receiver. The ray generator is equipped with a ray assembly, and the ray receiver is equipped with a linear array assembly for receiving X-rays emitted by the ray assembly. The detection channel is perpendicular to the X-rays emitted by the ray assembly.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, in an embodiment, a vertical detection device includes a ray generating unit 1, a ray receiving unit 2, and a detection channel 3. The detection channel 3 is arranged between the ray generating unit 1 and the ray receiving unit 2. The ray generating unit 1 is provided with a ray assembly 101, including a radiation source 103, a heat dissipation device, etc. The radiation source 103 generates stable X-rays. The ray receiving unit 2 is provided with a linear array assembly 201 for receiving the X-rays emitted by the ray assembly 101. The detection channel 3 is located between the ray assembly 101 and the linear array assembly, and is perpendicular to the X-rays emitted by the ray assembly 101. When the material passes through the vertically arranged detection channel 3, it does not contact the inner wall of the detection channel 3, which can effectively prevent mud and water paste in the material from sticking to each other in the middle of the identification channel and affecting the identification process. When the material passes through the vertical detection channel 3, the posture and speed of the material remain basically unchanged during free fall, avoiding the influence of posture and speed changes on the identification accuracy.

[0027] It should be noted that the detection channel 3 in the prior art is tilted. Figure 2 As shown, the material enters the inner cavity of the detection channel 3 at a certain speed. Due to the inclined setting, part of the material will slide along the side wall of the detection channel 3. When the material is wet, it will stick to the side wall and become gelatinized, resulting in inaccurate detection after the subsequent material enters. This embodiment improves on this technical problem by setting the detection channel 3 vertically, reducing the speed at which the material enters the detection equipment, ensuring that the material maintains vertical free fall motion in the detection channel 3 so that it does not contact the detection channel 3, and ensuring that the detection window on the side wall of the detection channel 3 is clean, thereby ensuring detection accuracy.

[0028] like Figure 1 As shown, the radiation assembly 101 includes a radiation shielding chamber 102 for preventing X-ray leakage, a radiation source 103 is arranged in the radiation shielding chamber 102, a collimator 104 is provided along the beam direction of the radiation source 103, the radiation shielding chamber 102 has a slit along the X-ray direction, and the two ends of the collimator 104 are connected to the radiation source 103 and the slit.

[0029] Specifically, a radiation shielding chamber 102 is provided in the radiation generating part 1, and the radiation source 103 is completely enclosed in the radiation shielding chamber 102. Generally, the shell of the radiation shielding chamber 102 is made of lead plate to prevent radiation leakage. The radiation source 103 generally also includes a cooling device, a heat dissipation device, etc. to ensure that the radiation source 103 stably outputs radiation of a certain frequency. The collimator 104 is set in the direction of the beam of the radiation source 103, and is used to adjust and limit the size and shape of the radiation beam to ensure that the radiation is irradiated on the object to be detected in a precise manner. The collimator 104 helps to ensure that the radiation beam only irradiates the area that needs to be detected, reducing potential risks to the surroundings; in a vertical detection device, the collimator 104 is usually tightly integrated with the radiation source and the detector to form a coordinated detection system. After being emitted by the radiation source 103, the radiation is constrained by the collimator 104 to form a light curtain, and then emitted after passing through the slit on the radiation shielding chamber 102; the width and length of the slit are precisely matched with the size of the collimator 104, ensuring that the irradiation width matches the detection channel 3, so as to match the size of the object to be detected and the position of the detection channel 3, ensuring that the radiation beam only irradiates the specified area.

[0030] like Figure 1 As shown, long holes 301 are provided on both sides of the detection channel 3 . The long holes 301 are arranged horizontally with the slit. X-rays are emitted from the slit and enter the detection channel 3 through the long holes 301 .

[0031] Specifically, the elongated holes 301 on either side of the detection channel 3 are used in conjunction with the slits in the radiation shielding chamber 102 to achieve more precise radiation control and detection. The elongated holes 301 are horizontally arranged along either side of the detection channel 3, respectively penetrating the radiation generating unit 1 and the radiation receiving unit 2. After being emitted by the radiation source 103, X-rays are confined by the collimator 104 and emitted through the slits to form a light curtain. The X-ray curtain enters the detection channel 3 through the elongated holes 301 in the radiation generating unit 1, irradiating the material entering the detection channel 3. After passing through the material, the X-rays pass through the elongated holes 301 in the radiation receiving unit 2, enter the shielding chamber of the linear array 201, and are received by the linear array 201. The shape and size of the elongated holes 301 are customized according to detection requirements to allow X-rays to pass through in specific directions and angles. The slits in the radiation shielding chamber 102 are horizontally aligned with the elongated holes 301 on either side of the detection channel 3, ensuring that the X-rays exit the slits and pass through the elongated holes 301 in a straight path, forming a precise beam.

[0032] like Figure 1 As shown, the elongated holes 301 are covered with a carbon fiber plate 302 .

[0033] Specifically, the long hole 301 is sealed with a carbon fiber plate 302 . The carbon fiber plate 302 has a low radiation absorption rate and high wear resistance, and can also have a good sealing effect on the shielding cavity of the radiation source 103 .

[0034] like Figure 1 As shown, a baffle is provided above the elongated hole 301 , and one end of the baffle is fixedly connected to the inner wall of the detection channel 3 .

[0035] Specifically, the inner folding baffle is set above the long hole 301 as an additional protective layer to prevent materials and muddy water from directly contacting the carbon fiber plate 302, preventing materials from impacting the wear-resistant plate, and preventing muddy water from flowing onto the carbon fiber plate 302 in the vertical channel; the material of the inner folding baffle needs to have sufficient strength and durability, while also considering corrosion resistance and impact resistance to adapt to harsh working environments. The design of the inner folding baffle should be compatible with the structure and size of the carbon fiber plate 302 to ensure that they can fit seamlessly to form an integrated protection system. The shareholder method of the inner folding baffle may be bolted, welded or snap-fitted to adapt to different installation environments.

[0036] like Figure 1 As shown, one end of the baffle is fixedly connected to the inner wall of the detection channel 3 , and the other end is bent into the detection channel 3 .

[0037] Specifically, one end of the baffle is fixedly connected to the inner wall of detection channel 3, providing a stable support point to ensure the baffle remains in place during operation. The other end of the baffle bends into detection channel 3. This design helps to redirect the flow of materials or fluids, preventing them from directly impacting or contaminating sensitive areas.

[0038] like Figure 1 As shown, a feed port is provided on the detection channel 3 , the feed port is located above the long strip hole 301 , and a lead curtain 401 is provided on the feed port.

[0039] Specifically, the feed port, through which materials enter the detection device, is positioned above the elongated aperture 301. This arrangement allows the entire material to pass through the X-ray path upon entering the detection channel 3, ensuring that the material is fully exposed to the X-rays. A lead curtain 401, covering the feed port as a radiation protection measure, effectively shields X-rays, preventing them from leaking to the external environment when materials enter or leave the detection channel 3. The lead curtain 401 is designed to open and close, facilitating the entry and exit of materials while maintaining a closed detection channel 3 when not in use.

[0040] like Figure 1 As shown, the feed port is arranged on the side of the detection channel 3, and the lead curtain 401 is arranged in a ring shape to cover the entire feed port.

[0041] Specifically, the height of the radiation receiving portion 2 is lower than that of the radiation generating portion 1, so one side of the feed port is located on the side of the radiation receiving portion 2. To facilitate the coordination of the feeding device (not shown) with the present detection device, the feed port can be configured as a three-sided ring. That is, a top plate 402 is sealed at the top of the detection channel 3, where the top plate 402 can be aligned with the top of the radiation generating portion 1, and the other three sides are sealed by a lead curtain 401, forming an annular lead curtain 401. The feeding device passes through the lead curtain 401 and extends above the detection channel 3, so that the material is transported into the detection channel 3 by the feeding device.

[0042] like Figure 2 As shown, the housings of the radiation generating part 1 and the radiation receiving part 2 are made of lead-containing material.

[0043] Specifically, after the X-ray passes through the slit and exits the radiation shielding chamber 102, there is still a gap before entering the detection channel 3. Therefore, in order to ensure the protection effect, the outer shell of the radiation generating part 1 and the radiation receiving part 2 is set to lead-containing material to effectively prevent X-ray leakage.

[0044] like Figure 2 As shown, both the ray generating unit 1 and the ray receiving unit 2 are provided with an inspection door 5 .

[0045] Specifically, in order to facilitate maintenance, inspection and access to internal components, the inspection door 5 needs to have good sealing performance to ensure that it can block radiation and prevent dust, moisture, etc. from entering the interior of the equipment when closed.

[0046] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0047] For ease of description, spatially relative terms such as "above," "on the upper surface of," "on top of," etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "on top of" other devices or structures would then be positioned as "below" or "below" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used herein should be interpreted accordingly.

[0048] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
