When the particle size of the object block to be separated is within the second threshold range, the execution method is switched to the spring plate mechanism. The first threshold range is smaller than the second threshold range.

[0010] As one of the optional solutions of this technical solution, when the object block to be separated is gangue, control the blowing mechanism and the spring plate mechanism to perform a switching operation according to the particle size of the gangue, so as to separate the gangue into the second collection chamber;

[0011] When the block to be separated is clean coal, the injection mechanism and the spring plate mechanism are closed so that the clean coal enters the first collection cavity under the action of free fall.

[0012] As one of the alternative solutions of this technical solution, the fixed end of the spring plate mechanism is installed at the bottom of the collection tank, and the free end of the spring plate mechanism faces the movement trajectory of the block and is used to reciprocate along the direction close to or away from the movement trajectory of the block.

[0020] (2) Beneficial effects

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] The utility model provides an intelligent dry separator for two products, comprising: a feeding device, an identification device, an execution device and a collection tank. The identification device is arranged on one side of the feeding device close to the discharge end, and is used for identifying a to-be-detected block on the feeding device and sending the identified information to the execution device. The execution device comprises: a cooperating blowing mechanism and a spring plate mechanism. The blowing mechanism and the spring plate mechanism are sequentially arranged below the feeding device along the movement track of the block. The spring plate mechanism is movably arranged in the collection tank to divide the collection tank into two collection chambers.

[0023] Specifically, the blocks are evenly dispersed by the feeding device, and then the identification device is used to detect the blocks to determine whether the current block is a to-be-separated block. For the convenience of understanding, clean coal and gangue are taken as examples. The gangue is the to-be-separated block. When the identification device detects that the current block is gangue, the corresponding category information, particle size information and position information are all transmitted to the execution device. Then, the execution device controls the blowing mechanism and the spring plate mechanism to perform a switching operation according to the particle size information to separate the gangue into the second collection chamber far from the feeding device. More specifically, when it is detected that the current gangue has a small particle size, the blowing mechanism is controlled to perform a separation operation on it, and when it is detected that the current gangue has a large particle size, the spring plate mechanism is controlled to perform a separation operation on it. Similarly, when the identification device detects that the current block is clean coal, a stop working signal is sent to the execution device so that the clean coal falls into the first collection chamber under the action of free fall. To sum up, the design of the present application can realize the simultaneous sorting of blocks with different particle sizes and improve the sorting efficiency. Description of the Drawings

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0033] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0034] To solve the technical problem that the existing dry separator can only perform high-precision separation on small particle size blocks, as Figures 1 - 5 shown in the spring plate mechanism, the present application provides a two-product intelligent dry separator, which is characterized by adopting an intelligent recognition method, establishing an analysis model adapted to different coal quality characteristics, through big data analysis, digitally identifying clean coal and gangue, and finally separating coal and gangue through an intelligent execution device. For the convenience of understanding, the following will take clean coal and gangue as examples for illustration, and gangue is the block to be separated. Of course, the design of the present application is not limited to the separation of clean coal and gangue, and can be applied to the separation between different ores.

[0035] The two-product intelligent dry separator specifically includes: a cloth feeding device 1, an identification device, an execution device, and a collection tank 2. The identification device is arranged on one side of the cloth feeding device 1 close to the discharge end, and is used to identify the block to be detected located on the cloth feeding device 1 and send the identified information to the execution device, where the information includes: category information, particle size information, and position information.

[0036] The actuating device includes a cooperating blowing mechanism 3 and a spring plate mechanism 4. The blowing mechanism 3 and the spring plate mechanism 4 are sequentially arranged below the cloth-feeding device 1 along the movement trajectory of the object block. The spring plate mechanism 4 is movably arranged in the collection tank 2 to divide the collection tank 2 into two collection chambers. Specifically, the one closer to the cloth-feeding device 1 is the first collection chamber 11, and the one farther from the cloth-feeding device 1 is the second collection chamber 12. Among them, the second collection chamber 12 is used to collect the object blocks to be separated (gangue), and the first collection chamber 11 is used to collect the clean coal that falls into it under the action of free fall.

[0037] Determine whether the current object block to be detected is an object block to be separated (gangue) according to the received information. If so, control the blowing mechanism 3 and the spring plate mechanism 4 to perform a switching operation according to the particle size of the object block to be separated, so as to separate the object block to be separated into the second collection chamber 12 located away from the cloth-feeding device 1. Specifically, when the particle size of the object block to be separated is within the first threshold range, the blowing mechanism 3 is started. At this time, the object block to be separated will move into the second collection chamber 12 under the action of the blowing force. When the particle size of the object block to be separated is within the second threshold range, the execution mode is switched to the spring plate mechanism 4. The first threshold range is smaller than the second threshold range. At this time, the object block to be separated will fall into the second collection tank 12 under the action of the spring plate mechanism 4. Exemplarily, the first threshold range can be 35mm - 200mm, and the second threshold range can be 201mm - 550mm. Of course, the above two threshold ranges can be set independently in advance as needed. Similarly, if it is determined that the current object block to be detected is not an object block to be separated (clean coal), the control module controls the actuating device to stop working. At this time, the clean coal will continue to move on the cloth-feeding device 1 until it flows out from the discharge end of the cloth-feeding device 1, and then falls into the first collection tank 11 under the action of free fall.

[0038] Specifically, in the above embodiment, the object blocks are evenly dispersed by the cloth-feeding device 1 so that multiple object blocks are arranged one by one and do not overlap on the cloth-feeding device 1, thereby improving the recognition efficiency and avoiding errors. Then, the recognition device is used to detect the object blocks to determine whether the current object block is an object block to be separated. When the recognition device detects that the current object block is gangue, the corresponding category information, particle size information, and position information are all transmitted to the actuating device. Then, the actuating device controls the blowing mechanism 3 and the spring plate mechanism 4 to perform a switching operation according to the particle size information to separate the gangue into the second collection chamber 12 located away from the cloth-feeding device 1. More specifically, when it is detected that the current gangue has a small particle size, the blowing mechanism 3 is controlled to perform a separation operation on it. When it is detected that the current gangue has a large particle size, the spring plate mechanism 4 is controlled to perform a separation operation on it. Similarly, when the recognition device detects that the current object block is clean coal, a stop working signal is sent to the actuating device so that the clean coal falls into the first collection chamber 11 under the action of free fall. In summary, the design of the present application can realize the simultaneous sorting of object blocks with different particle sizes and improve the sorting efficiency.

[0039] According to an embodiment of the present utility model, the identification device at least includes a cooperating X-ray source 8 and a linear array detector 9. The X-ray source 8 is located above the cloth feeding device 1, and the linear array detector 9 is located below the cloth feeding device 1. In this embodiment, the clean coal and gangue are identified based on the physical properties of the clean coal and gangue, and the function of the X-ray to detect the size of the object block is utilized to judge the particle size.

[0040] Furthermore, the identification device may further include an image detection mechanism, such as a camera, etc. By taking pictures of the object block to be detected and comparing the pictures or colors, it can be quickly determined whether the current object block is gangue (the object block to be separated).

[0041] In a preferred embodiment, the blowing mechanism 3 has a plurality of nozzles arranged in an array. The sizes of the plurality of nozzles may be the same or different. The air nozzles at the corresponding positions are intelligently opened according to the received position information of the object block to be separated, so as to ensure that no matter where the object block to be separated is located on the cloth feeding device 1, after the identification device accurately gives its position, through the operation of the electric control system, the execution device can always find one or more air nozzles at its corresponding position and intelligently open them within the set time; furthermore, in order to improve the cooperation with the blowing mechanism, the corresponding elastic plate mechanism 4 is also correspondingly set to be a plurality, and the plurality of elastic plate mechanisms 4 are arranged at intervals along the length direction of the mounting plate.

[0042] According to an embodiment of the present utility model, the fixed end of the elastic plate mechanism 4 is installed at the bottom of the collection tank 2, and the free end of the elastic plate mechanism 4 faces the movement track of the object block and is used for reciprocating along the direction close to or away from the movement track of the object block.

[0043] On the basis of the above embodiment, preferably, the dry separation machine further includes: an inclined slide plate 10 with a preset angle. The slide plate 10 is arranged at the feeding end of the cloth feeding device 1. This design can ensure that the object block falls into the cloth feeding device 1 after being buffered by the slide plate 10, so as to ensure that the object block moves stably along with the cloth feeding device 1.

[0044] According to an embodiment of the present utility model, as Figure 3As shown in the figure, an installation plate 5 is arranged vertically in the collection tank 2. The elastic plate mechanism 4 includes a matching drive assembly 6 and a separation plate 7. The middle of the separation plate 7 is rotatably connected to the installation plate 5. One end of the drive assembly 6 is rotatably connected to the tail end of the separation plate 7, and the other end is rotatably connected to the installation plate 5. Exemplarily, the drive assembly 6 can be a linear mechanism such as a drive cylinder or a telescopic cylinder, which is not specifically limited in this embodiment; specifically, when it is detected that the particle size of the current object block to be separated is within the second threshold range, the telescopic end of the drive assembly 6 is prompted to extend, thereby driving the free end of the separation plate 7 to move in the direction close to the movement trajectory of the object block until the free end of the separation plate 7 abuts against the movement trajectory of the object block, specifically as Figure 4 the jetting mechanism and Figure 2 shown. After that, the large-particle-size object blocks to be separated (gangue) will move along the side of the separation plate away from the drive assembly 6 until they flow into the second collection cavity 12 from the tail end of the separation plate 7; similarly, when the separation is completed, the drive assembly 6 is driven again to shorten its telescopic end, so that the drive assembly 6 drives the separation plate 7 to move away from the movement trajectory of the object block until the free end of the separation plate is separated from the movement trajectory of the object block without interfering with the original movement trajectory, so that the non-object blocks to be separated (clean coal) can move along the movement trajectory to the first collection cavity 11 under the action of free fall.

[0045] On the basis of the above embodiment, in order to make it more conducive for the object blocks to be separated to move along the separation plate 7 towards the second collection cavity 12, the end of the separation plate 7 facing the movement trajectory of the object block is set as an upwardly curved arc structure.

[0046] During operation, multiple object blocks move along the slide plate to the cloth feeding device 1. After that, under the action of the cloth feeding device 1, the multiple object blocks are arranged one by one on the cloth feeding device 1 without overlapping, thereby improving the recognition efficiency and avoiding errors; then, under the action of the cloth feeding device 1, the object block to be detected moves to the recognition area of the recognition device. At this time, the physical properties of clean coal and gangue are used to distinguish whether the current object block to be detected is clean coal or gangue, as well as information such as the size and position of the corresponding object block to be detected, and the above information is sent to the execution device to separate the clean coal into the first collection cavity 11 and the gangue into the second collection cavity 12 by using different execution modes.

[0047] Specifically, when it is detected that the current object block to be detected is gangue, the corresponding category information, particle size information, and position information are all transmitted to the execution device. When it is detected that the particle size of the gangue is within the first threshold range, as Figure 1 shown, the corresponding nozzle in the jetting mechanism 3 is controlled to jet the corresponding small-particle-size gangue into the second collection cavity 12; and when it is detected that the particle size of the gangue is within the second threshold range, as Figure 2As shown, the control of the injection mechanism 3 stops working, and the corresponding elastic plate mechanism 4 is activated to separate the corresponding large-sized gangue into the second collection chamber. Specifically, the telescopic end of the driving component 6 is extended, so as to drive the free end of the separation plate 7 to move in the direction close to the movement trajectory of the object block until the free end of the separation plate 7 abuts against the movement trajectory of the object block. Specifically, as shown in Figure 4 the injection mechanism and Figure 2 As shown, the large-sized object block to be separated (gangue) will move along the separation plate away from the driving component 6 until it flows into the second collection chamber 12 from the tail end of the separation plate 7.

[0048] When it is detected that the current object block to be detected is clean coal, the driving component 6 is driven again to shorten its telescopic end, so that the driving component 6 drives the separation plate 7 to move away from the movement trajectory of the object block until the free end of the separation plate 7 is separated from the movement trajectory of the object block without interfering with the original movement trajectory. At this time, after the clean coal flows out of the discharge end of the feeding device 1, the clean coal will fall into the first collection chamber 11 under the action of free fall. Thus, the full separation of clean coal and gangue is realized. In summary, the design of the present application can realize the simultaneous separation of object blocks with different particle sizes and improve the separation efficiency.

[0049] Each embodiment in this specification is described in a progressive manner. The differences between several embodiments are mainly described. The same or similar parts among the embodiments can be referred to each other. Then a stop working signal is sent to the execution device so that the clean coal falls into the first collection chamber under the action of free fall; In summary, the design of the present application can realize the simultaneous separation of object blocks with different particle sizes and improve the separation efficiency.
