Detailed Description

The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person skilled in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

In ore sorters, X-ray machines (or X-ray machines) are one of the key devices. When the X-ray machine works, certain heat can be generated, if the heat cannot be timely emitted, the normal work of the X-ray machine can be seriously influenced, and even the machine parts are overheated and damaged. Therefore, the heat dissipation design of the X-ray machine is very important.

The importance of heat dissipation of X-ray machines is mainly represented in the following aspects: a. ensuring machine performance. The operation of X-ray machines depends on precision equipment such as tube, the performance of which varies with temperature. Only by good heat dissipation, the temperature of the machine is controlled in the optimal working range, and the performance of the X-ray machine can be fully exerted. b. Ensuring the stability of the machine. As a key component of the sorter, the X-ray machine must be extremely stable and reliable in operation. If the temperature in the machine is too high, the aging of the components can be accelerated, errors are increased, and the working stability is affected. Severe cases may lead to machine overheating and shutdown. c. Prolonging the service life of the machine. The life of the internal parts of the X-ray machine is closely related to the working environment temperature. When the temperature rises by 10 ℃, the service life of the machine parts is reduced by about half. The service life of key components can be prolonged to the greatest extent by good heat dissipation, and maintenance and replacement are reduced. d. Preventing the machine from overheating and damaging. If the heat generated in the operation of the X-ray machine can not be released for a long time, the temperature in the machine is too high, and the components such as the ray tube, the electronic component and the like can be subjected to irreversible heat damage, so that the machine is directly damaged and stopped. This results in a large economic loss. e. And the sorting precision is improved. The detection accuracy of the X-ray machine is also affected by temperature. The excessive temperature can cause the reduction of the fluorescence intensity generated by X-rays, influence the identification of the internal structure of the ore and reduce the precision.

Therefore, the heat dissipation design of the X-ray detector is significant for normal and stable operation. The good heat radiation system can exert the performance of the X-ray machine to the maximum extent, ensure the high-precision stable work of the machine, prolong the service life of machine parts, prevent overheat damage and further ensure the precision and efficiency of ore sorting. Radiation of X-ray machine is one of the key factors in the design of the classifier.

Mineral processing apparatuses in the form of containers are usually of modular design, wherein the X-ray machine also has modular features. The heat radiation structure of X-ray machine includes the forms of X-ray machine body heat radiation, radial heat radiation fan heat radiation, heat exchanger heat radiation, etc. For heat dissipation of the heat exchanger, the heat exchanger is generally circulated with a certain volume of cooling liquid or cooling water, and then the heat of the X-ray machine is dissipated through a fan and other structures. This liquid cooling mode works best.

However, in the heat dissipation process of the heat exchanger in specific application, the applicant finds that the heat exchanger selected by the sorting equipment exchanges heat in the equipment, and the heat dissipation effect is poor because the temperature in the equipment is higher. If the top frame of the optical engine is arranged, the disassembly is needed during transportation possibly because the height of the automobile is limited or the height of the container is limited. If the cooling water pipes are arranged at the front and rear parts of the frame, the required cooling water pipes are additionally lengthened, the power of the required driving water pump is increased, and the overall arrangement of the appearance is not facilitated.

In view of this, the present embodiment provides a heat dissipation structure of an optical recognition device, which aims to solve the above-mentioned problems by improving the structure thereof. It should be noted that, the heat dissipation structure of this embodiment may be applied to ore sorting equipment on a chassis, a cabinet, a container, or other sorting equipment with similar structures.

The following describes a heat dissipation structure of the optical recognition device according to the present embodiment with reference to fig. 1 to 5.

The heat exchange device 300 of the present embodiment is used for heat dissipation of the optical recognition device, and the heat exchange device 300 includes a first heat exchanger 310 mounted on the turnover device 200.

The turnover device 200 is configured to urge the heat exchange device 300 to be located outside the cabinet 100 when the turnover device stays at the first position in fig. 2 and 3, so that the first heat exchanger 310 exchanges heat with the outside, and the problem of poor heat dissipation effect of the first heat exchanger 310 in the cabinet 100 is solved. While in the second position of fig. 4 and 5, heat exchange device 300 is urged to reside within cabinet 100, thereby not affecting the transport of cabinet 100.

In one example, the flipping unit 200 of the present embodiment is configured to close the opening 110 in both the first position and the second position. The structure for closing the opening 110 in both the first position and the second position may be: the flipping unit 200 is designed to include a first and a second vertical and connected flap assemblies 210 and 220; the first plate turnover assembly 210 and the second plate turnover assembly 220 of the present embodiment are hinged to the cabinet 100 through respective hinge structures, and the first heat exchanger 310 of the present embodiment is mounted on the first plate turnover assembly 210.

As such, referring to fig. 2 and fig. 3 again, when in the first position, the first flap assembly 210 of the present embodiment closes the opening 110 and can be locked and fixed with the cabinet 100, and at this time, the second flap assembly 220 and the first heat exchanger 310 of the present embodiment are located outside the cabinet 100. Referring again to fig. 4 and 5, in the second position, the second flap assembly 220 of the present embodiment closes the opening 110 and is capable of being locked and secured to the cabinet 100 such that the first flap assembly 210 and the first heat exchanger 310 are located within the cabinet 100.

Of course, the structural form of the turnover device 200 for closing the opening 110 in both the first position and the second position is not limited thereto, and for example, two mutually hinged plates (such an embodiment is not shown in the drawings) may be designed, and the two plates are hinged to the cabinet 100 together through one hinge, then the first heat exchanger 310 is installed on one of the plates, and the corresponding plate is selected to be in locking connection with the cabinet 100 according to different requirements, so that the above-mentioned functions can also be achieved.

In one example, the first and second flap assemblies 210 and 220 of the present embodiment are perpendicular and interconnected by providing the link 230 and the elastic support mechanism 240. Specifically, the first plate turnover assembly 210 and the second plate turnover assembly 220 of the present embodiment are hinged to the cabinet 100 through hinges, and two connecting rods 230 are disposed between the first plate turnover assembly and the second plate turnover assembly, and the two connecting rods 230 are respectively located at the left and right sides of the first heat exchanger 310; one end of the connecting rod 230 is hinged with the first flap assembly 210 through the first mounting seat 215, and the other end is hinged with the second flap assembly 220 through the second mounting seat 223.

Further, an elastic supporting mechanism 240 is mounted on the second flap assembly 220 of the present embodiment, and one end of the elastic supporting mechanism 240 is hinged to the second flap assembly 220, and the other end is hinged to the cabinet 100. And in the second position, the resilient support mechanism 240 of the present embodiment is compressed to facilitate rotation of the second flap assembly 220 of the present embodiment when the transport condition is switched to the heat exchange condition. Alternatively, the elastic support mechanism 240 of the present embodiment is a nitrogen spring. The nitrogen spring is a device for generating elastic action by utilizing nitrogen pressure, has the advantages of simple structure, convenient control, reliable operation and the like, and is a high-performance elastic element.

In addition, in order to facilitate stable resting of the turning device 200 in the first position and the second position, the present embodiment designs the first flap assembly 210 to include the first flap body 211 and a first locking mechanism (not shown in the drawings), and the second flap assembly 220 includes the second flap body 221 and a second locking mechanism (not shown in the drawings). The first flap body 211 and the second flap body 221 of the present embodiment are used for closing the opening 110, and the first locking mechanism and the second locking mechanism of the present embodiment are used for detachably connecting with the cabinet 100, so that the turning device 200 can be fixedly connected with the cabinet 100 in the first position and the second position.

Further, the first locking mechanism of the present embodiment includes a first locking bolt (not shown in the figure), and the cabinet 100 is provided with a first screw hole (not shown in the figure) adapted to the first locking bolt. Similarly, the second locking mechanism of the present embodiment includes a second locking bolt, and the cabinet 100 is provided with a second screw hole adapted to the second locking bolt. The connection between the first plate turnover assembly 210 and the second plate turnover assembly 220 and the cabinet 100 is realized through the connection of the bolts and the screw holes, so that the structure is simple, the operation is easy, and the stability of the turnover device 200 and the first heat exchanger 310 in the first position and the second position can be ensured.

Referring to fig. 3 again, in order to facilitate the turning device 200 of the present embodiment to rotate between the first position and the second position, the first turning plate assembly 210 of the present embodiment is provided with a first handle 212, and the second turning plate assembly 220 is provided with a second handle 222, so that an operator can drive the turning device 200 to rotate through the handles.

Of course, the structural form of the turning device 200 according to the present embodiment is not limited to this, and the turning device 200 may be turned by a motor, an electric rod, a pneumatic rod, or the like, for example, which is not illustrated in the present embodiment.

In order to improve the stability of the first heat exchanger 310 of the present embodiment on the first flap body 211, the present embodiment mounts the first heat exchanger 310 on the side of the first flap body 211 facing the second flap body 221 by a connection screw, and designs the first flap assembly 210 to further include an auxiliary stopper 213 vertically mounted on the first flap body 211. The auxiliary stopper 213 may be an alloy member having an L-shaped cross section in fig. 1, or a channel structure in fig. 3.

Referring to fig. 1 and 3 again, the auxiliary blocking member 213 of the present embodiment is located on a side of the first heat exchanger 310 facing away from the second plate assembly 220, and supports the first heat exchanger 310 in the second position, so as to prevent the connection screw between the first heat exchanger 310 and the first plate body 211 from loosening after rotation.

Referring to fig. 1 again, a heat dissipation area 311 is disposed on a side of the first heat exchanger 310 facing away from the second flap body 221, so that in order to avoid affecting heat dissipation of the heat dissipation area 311 of the first heat exchanger 310 in this embodiment, two auxiliary blocking members 213 in this embodiment may be disposed on two sides of the heat dissipation area 311 in a one-to-one correspondence manner. In addition, a plurality of through holes 2211 may be formed in the second flap body 221 of the present embodiment, so as to facilitate heat dissipation of the first heat exchanger 310 of the present embodiment.

Referring again to fig. 3, in one example, to further improve the structural stability of the auxiliary stopper 213, deformation of the first heat exchanger 310 of the present embodiment is prevented when it is supported in a horizontal state. The first flap assembly 210 of the present embodiment also includes an auxiliary support 214. One end of the auxiliary supporting member 214 is connected with the first board body 211 at an angle, and the other end is connected with the auxiliary blocking member 213 at an angle, and the auxiliary supporting member 214 plays a role of reinforcing support.

In addition to the above structure, the heat exchange device 300 of the present embodiment further includes a second heat exchanger and a pipeline (not shown in the figures), where the second heat exchanger is connected to or disposed in the optical recognition device. The piping of the present embodiment is used to connect the second heat exchanger with the first heat exchanger 310 and enable the heat exchange medium charged into the first heat exchanger 310 to circulate between the second heat exchanger and the first heat exchanger 310. It should be noted that, since the second heat exchanger and the pipeline are both the structures of the conventional heat exchange device 300, the description of the drawings and the structure of the two are not described in this embodiment.

Based on the above heat exchange structure, the present embodiment provides an ore sorting apparatus, which includes the heat dissipation structure of the optical recognition device according to the above technical solution, and since the improvement of the ore sorting apparatus of the present embodiment mainly resides in the heat exchange structure, fig. 2-5 only show part of the structure of the ore sorting apparatus of the present embodiment, and a person skilled in the art can understand with reference to the existing ore sorting apparatus.
