[0002] In the process of dry air separation, the fluidization state has a significant impact on the separation results. Only when the bed material is in a good fluidization state can the material layer be in a loose and suspended state, the mechanical resistance between particles decreases, high-density gangue can be fully fluidized and enter the lower layer through the particle gaps, and low-density clean coal enters the upper layer. The bed material is stratified from top to bottom according to density.

[0003] Currently, in the dry separation process, the bed material is affected by the quality of the raw coal (gangue content, feed rate, moisture content, powder content, etc.), and cannot always be in a good fluidized state. As a result, the staff cannot understand the fluidization state of the bed material in a timely manner, leading to poor separation effect of the equipment. Utility Model Content

[0014] In one possible implementation, the housing includes a base and an end cap, the end cap being detachably connected to the base;

[0015] The end cap has a through hole, and the pressure connecting rod passes through the through hole and is connected to the pressure sensor. A gap is formed between the pressure connecting rod and the through hole.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0035] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] As described in the background section, in the related technical solutions, the bed material during the dry separation process is affected by the quality of the raw coal and cannot always be in a good fluidized state. As a result, the staff cannot understand the fluidization state of the bed material in a timely manner, leading to poor separation effect of the equipment.

[0037] In view of this, the embodiments of this application aim to provide a fluidization detection device and a dry sorting equipment. By installing the detection device in the air supply duct, the air in the air supply duct blows onto the windward component. Since the windward component, pressure connecting rod and pressure sensor are connected as one unit, the windward component can drive the pressure sensor to deform. The pressure sensor can then output the corresponding pressure value. The operator can indirectly correspond to the fluidization state of the material on the bed based on the pressure value, which is convenient for corresponding processing according to different fluidization states and helps to improve the sorting effect of the equipment.

[0038] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the contents of this application.

[0039] Please refer to Figure 1 This embodiment provides a fluidization detection device for installation in an air supply duct, comprising:

[0040] The housing 100 contains a pressure sensor 200. The shape of the housing 100 can be customized as needed, for example, it can be cylindrical or prismatic. A cavity is formed inside the housing 100, and the pressure sensor 200 can be fixedly installed inside the cavity.

[0041] A wind-facing component 300 is disposed on the windward side of the housing 100; that is, the wind-facing component 300 is disposed on the side of the housing 100 facing the direction of the incoming airflow into the air supply duct. For example, as... Figure 1 As shown, the air in the air supply duct flows vertically from bottom to top, and the windward component 300 is located below the outer casing 100.

[0042] A pressure connecting rod 400 has its first end connected to the windward component 300, and its second end passing through the housing 100 and connected to the pressure sensor 200. Exemplarily, the first end of the pressure connecting rod 400 can be connected to the windward component 300 via bolts, etc., and the second end of the pressure connecting rod 400 may have a threaded section. The pressure sensor 200 has a threaded hole, and the second end of the pressure connecting rod 400 is threadedly connected to the pressure sensor 200. The pressure connecting rod 400 connects the windward component 300 and the pressure sensor 200 as a single unit. When air from the air supply duct blows onto the windward component 300, the windward component 300 can deform the pressure sensor 200 via the pressure connecting rod 400, thereby causing the pressure sensor to output a corresponding pressure value.

[0043] A connecting rod 500 is provided, with its first end connected to the housing 100 and its second end fixedly connected to the air supply duct. The pressure sensor 200 communicates with external equipment via the connecting rod 500. Exemplarily, in this embodiment, the first end of the connecting rod 500 can be threaded to the housing 100, and the second end of the connecting rod 500 can also be threaded to the air supply duct, or it can be connected to the outer wall of the air supply duct via an adapter. The connecting rod 500 provides support for other components of the detection device, allowing them to be stably installed within the air supply duct. The connecting rod 500 can be hollow, allowing the communication harness of the pressure sensor 200 to communicate with external equipment via the connecting rod 500, thereby transmitting the detected pressure data to the external equipment.

[0044] Since the detected pressure value is directly proportional to the air velocity in the air supply duct, which in turn is directly proportional to the apparent air velocity of the sorting bed, and the apparent air velocity of the bed is directly proportional to the fluidization state of the material on the bed surface, the detected pressure value can indirectly reflect the fluidization state of the material on the bed surface. For example, the pressure value of the material on the bed surface in different fluidization states (including unfluidized, fluidized, and over-fluidized states) can be detected before use to determine the corresponding pressure value range. During use, the current fluidization state of the material on the bed surface can be determined by comparing the detected pressure value with the pressure value range under different fluidization states.

[0045] In this embodiment, when the detection device is in use, the air in the air supply duct blows onto the windward component 300. Since the windward component 300, the pressure connecting rod 400, and the pressure sensor 200 are connected as one unit, the windward component 300 can drive the pressure sensor 200 to deform. The pressure sensor 200 can then output a corresponding pressure value. The operator can indirectly correspond to the fluidization state of the material on the bed based on the pressure value, which is convenient for corresponding processing according to different fluidization states and helps to improve the sorting effect of the equipment.

[0046] In one possible implementation, the windward component 300 of this embodiment is a windward plate 310, which is arranged perpendicular to the pressure connecting rod 400; that is, the windward plate 310 is perpendicular to the airflow direction in the air supply duct. This structure ensures that the windward plate 310 fully contacts the airflow in the air supply duct, with no wasted area. This structure is suitable for installation in horizontally arranged air supply ducts.

[0047] Please continue to refer to Figure 1 In another possible implementation, the windward component 300 of this embodiment includes a windward plate 310 and a windward side plate 320. The windward side plate 320 is inclined to the windward plate 310 and is located on the side of the windward plate 310 away from the outer shell 100. The windward plate 310 is circular, and the windward side plate 320 surrounds the circumference of the windward plate 310. The windward plate 310 and the windward side plate 320 together form a conical windward cap. The closed end of the windward cap (i.e., the windward plate 310) is connected to the pressure connecting rod 400.

[0048] In this embodiment, by setting the windward component 300 as a conical windward cap, the wind resistance experienced by the windward component 300 can be increased; and when the air in the air supply duct flows vertically from bottom to top, it can prevent the material mixed in the air from accumulating on the windward component 300, thus ensuring the accuracy of pressure value detection.

[0049] Please continue to refer to Figure 1 In another possible implementation, the windward component 300 of this embodiment includes a windward plate 310 and a plurality of windward side plates 320. The plurality of windward side plates 320 are inclined to the windward plate 310 and located on the side of the windward plate 310 away from the outer shell 100. The windward plate 310 is polygonal. The plurality of windward side plates 320 are respectively connected to one side of the windward plate 310. The plurality of windward side plates 320 are connected to each other along the outer periphery of the windward plate 310 to form a multi-faceted windward cap. The closed end of the windward cap (i.e., the windward plate 310) is connected to the pressure connecting rod 400.

[0050] In this embodiment, by setting the windward component 300 as a multi-faceted pyramidal windward cap, the wind resistance experienced by the windward component 300 can be increased; and when the air in the air supply duct flows vertically from bottom to top, it can prevent the material mixed in the air from accumulating on the windward component 300, thus ensuring the accuracy of pressure value detection.

[0051] Optionally, in this embodiment, the maximum diameter d of the wind-facing plate 310 or the maximum inner diameter d of the wind-facing cap is 1 / 10 to 1 / 2 of the diameter of the air supply duct. It is understood that if the maximum diameter d of the wind-facing plate 310 or the maximum inner diameter d of the wind-facing cap is too large, the wind-facing component 300 may affect the normal air supply of the air supply duct. If the maximum diameter d of the wind-facing plate 310 or the maximum inner diameter d of the wind-facing cap is too small, the pressure change detected by the detection device may not be significant. Therefore, setting the maximum diameter d of the wind-facing plate 310 or the maximum inner diameter d of the wind-facing cap within the above-mentioned range allows the detection device to accurately reflect the pressure changes of the bed material under different fluidization states without affecting the normal air supply of the air supply duct.

[0052] Optionally, in this embodiment, the cone angle α of the wind-facing cap is preferably 60°-120°. It can be understood that a cone angle α within the above range can prevent materials carried in the wind from accumulating on the wind-facing component 300, and can also prevent the wind-facing component 300 from occupying too much space in the air supply duct, thus ensuring the normal air supply of the air supply duct.

[0053] Please continue to refer to Figure 1 In this embodiment, the housing 100 includes a base 110 and an end cap 120, which are detachably connected to the base 110. For example, the end cap 120 can be detachably connected to the base 110 by fasteners such as screws, thereby facilitating the installation of the pressure sensor 200 and its disassembly during subsequent maintenance.

[0054] The end cap 120 has a through hole, through which the pressure connecting rod 400 passes and connects to the pressure sensor 200. A gap is formed between the pressure connecting rod 400 and the through hole, which can be, for example, 1-2 mm. That is to say, in this embodiment, the pressure connecting rod 400 will not come into contact with the outer casing 100, thereby ensuring the accuracy of the pressure value measurement.

[0055] Furthermore, in this embodiment, the end cap 120 facing the base 110 is also provided with a mounting groove 121. A sealing element, such as a sealing ring, is provided in the mounting groove 121. The first end of the sealing element abuts against the mounting groove 121, and the second end of the sealing element abuts against the pressure sensor 200. The pressure connecting rod 400 passes through the sealing element, and a gap is formed between the pressure connecting rod 400 and the sealing element. In this embodiment, by providing a sealing element, the interior of the housing 100 can be kept sealed, preventing materials mixed in with the air supply duct from entering the interior of the housing 100, thus ensuring the service life of the pressure sensor 200.

[0056] Please continue to refer to Figure 1In this embodiment, the base 110 is provided with a slot 111. The slot 111 is located at the end of the base 110 away from the end cover 120. Some pressure sensors 200 are locked in the slot 111. By limiting the position of the slot 111, the pressure sensor 200 can be prevented from rotating in the housing 100.

[0057] The detection device also includes a fastener 600, which can be, for example, a screw or bolt. The fastener 600 passes through the base 110 and is fixedly connected to the pressure sensor 200, thereby fixing the pressure sensor 200 inside the housing 100.

[0058] Please continue to refer to Figure 2 This embodiment also provides a dry sorting device, including a sorting bed 10 and an air supply pipe, the air supply pipe being connected to the sorting bed 10, and the aforementioned fluidization detection device being provided inside the air supply pipe.

[0059] It is understood that, since the dry sorting equipment of this embodiment is equipped with the above-mentioned fluidization detection device, it is convenient for the staff to understand the fluidization state of the material on the sorting bed 10 at any time, which is conducive to improving the sorting effect of the equipment.

[0060] In this embodiment, the air supply duct includes a main air supply duct 21 and multiple branch air supply ducts 22. The main air supply duct 21 is horizontally arranged, and the multiple branch air supply ducts 22 are all connected to the main air supply duct 21 and are vertically arranged. The fluidization detection device is installed in the main air supply duct 21 and / or the branch air supply ducts 22.

[0061] For example, when the fluidization detection device is installed in the main air supply duct 21, the windward component 300 may only include the windward plate 310. In this case, the windward plate 310 is vertically installed, and the material mixed in the wind can slide off the windward plate 310 under the action of gravity, thereby avoiding accumulation on the windward plate 310.

[0062] When the fluidization detection device is installed in the air supply branch pipe 22, the windward component 300 may include a windward plate 310 and a windward side plate 320. The windward side plate 320 can increase the wind resistance of the windward component 300; and can prevent the accumulation of materials carried in the wind on the windward component 300, thus ensuring the detection accuracy of the pressure value.

[0063] It is understandable that, in order to improve the accuracy of pressure detection, fluidized bed detection devices can be installed simultaneously in the main air supply pipe 21 and multiple air supply branch pipes 22, and the pressure value can be the average value detected by multiple fluidized bed detection devices.
