[0021] The embodiments of the present application will be described in detail below with reference to the drawings.

[0022] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] The embodiment of the present application provides a simple structure of the locking device of the high-pressure gas pulverized ore device, which is convenient for connecting the high-pressure bin and the collection bin of the high-pressure gas pulverized ore device.

[0024] The embodiments of the present application will be described in detail below with reference to the drawings. Figures 1 to 4 , further described.

[0025] Figure 1 It is a three-dimensional structural schematic diagram of one embodiment of the locking device of the high-pressure gas pulverized ore device, referring to Figure 1 The locking device of the high-pressure gas pulverized ore device of the embodiment includes a flange 1, a connecting shaft 2 and an operating assembly.

[0026] The flange 1 is provided with a first through hole in the axial direction.

[0027] The connecting shaft 2 includes a connecting part 21, an operating part 22 and a through hole penetrating the connecting part 21 and the operating part 22, the connecting part 21 is inserted into the first through hole and fixedly connected with the flange 1, and the second through hole is used for connecting with the high-pressure bin of the high-pressure gas pulverized ore device. The connecting part 21 of the high-pressure bin can pass through the through hole into the collection bin, so as to deliver the crushed ore powder into the collection bin.

[0028] The operating assembly is arranged on the side surface of the operating part 22, which is used for driving the connecting shaft 2 to rotate around its axis, and further driving the flange 1 to rotate around its axis, and locking with the collection bin of the high-pressure gas pulverized ore device.

[0029] The locking device of the high-pressure gas pulverized ore device provided by the embodiment of the application is provided with a first through hole in the axial direction of the flange 1, the connecting portion 21 of the connecting shaft 2 is inserted into the first through hole and is fixedly connected with the flange 1, the side surface of the operating portion 22 of the connecting shaft 2 is provided with an operating assembly, the connecting shaft 2 can be driven to rotate around the axis thereof through the operating assembly, and then the flange 1 is driven to rotate around the axis thereof, thereby locking the collecting bin of the high-pressure gas pulverized ore device, and the through hole can be connected with the high-pressure bin of the high-pressure gas pulverized ore device, so that the high-pressure bin of the high-pressure gas pulverized ore device is conveniently connected with the collecting bin.

[0030] In an embodiment, the side surface of the flange 1 is provided with external threads.

[0031] For example, the connecting portion 21 of the collecting bin of the high-pressure gas pulverized ore device can be provided with internal threads, so that the flange 1 is driven to rotate around the axis thereof through the operating assembly driving the connecting shaft 2 to rotate around the axis thereof, and then the external threads on the side surface of the flange 1 are threadedly matched with the internal threads of the collecting bin, thereby locking the collecting bin of the high-pressure gas pulverized ore device.

[0032] Referring to Figure 2 In an embodiment, the operating assembly includes at least two operating rods 3, and the operating rods 3 are circumferentially and uniformly arranged on the side surface of the operating portion 22 of the connecting shaft 2. In this way, by arranging a plurality of operating rods 3, on the one hand, the flexibility of the operating assembly is enhanced by applying force at different positions and angles, and on the other hand, the connecting shaft 2 is uniformly stressed by simultaneously applying force through the plurality of operating rods 3, thereby avoiding damage to the connecting shaft 2 due to local overload.

[0033] Referring to Figure 3 In an embodiment, the operating assembly includes four operating rods 3, and the operating rods 3 are circumferentially and uniformly arranged on the side surface of the operating portion 22 of the connecting shaft 2, and the axis of the operating rod 3 is perpendicular to the axis of the connecting shaft 2.

[0034] In an embodiment, the side surface of the operating portion 22 of the connecting shaft 2 is provided with at least two connecting holes, and the at least two operating rods 3 are correspondingly inserted into the at least two connecting holes, that is, the side surface of the operating portion 22 of the connecting shaft 2 is circumferentially and uniformly provided with at least two connecting holes, and each operating rod 3 is inserted into a corresponding connecting hole.

[0035] The inner wall of each connecting hole is provided with internal threads, and the side surface of each operating rod 3 close to the top end is provided with external threads, and the internal threads are matched with the external threads. At this time, part of the operating rods 3 are located outside the connecting holes and can be used to operate the operating rods 3. The operating rods 3 are pressed against the high-pressure bin of the high-pressure gas pulverized ore device in the first through hole through the matching between the external threads of the operating rods 3 and the internal threads of the connecting holes, thereby connecting the high-pressure bin and the collecting bin into an integral whole.

[0036] In an embodiment, the operating rod 3 is in the shape of a truncated cone, the top end of the operating rod 3 is the upper base; the shape of the connecting hole is matched with the shape of the operating rod 3.

[0037] That is, the bottom of the operating rod 3 is wider, and the top is narrower, so that the operating rod 3 is easier to be inserted into the connecting hole under the guidance of its own shape and the shape of the connecting hole when it is inserted into the connecting hole.

[0038] In addition, compared with the cylindrical operating rod 3, the contact area of the truncated cone-shaped operating rod 3 and the matched connecting hole is larger, so that the operating rod 3 and the connecting hole have greater friction, which can enhance the tightness of the connection between the operating rod 3 and the connecting hole.

[0039] In order to avoid the retention of the ore powder generated in the high-pressure bin in the first through hole of the flange plate 1, in an embodiment, the free end of the connecting part 21 of the connecting shaft 2 protrudes out of the first through hole. In this way, after the connecting part 21 of the high-pressure bin passes through the through hole of the connecting shaft 2, it is directly located in the collection bin, which can avoid the retention of the ore powder generated in the high-pressure bin in the first through hole of the flange plate 1.

[0040] Referring to Figure 4 In an embodiment, a clamping groove is arranged on the protruding section of the free end of the connecting part 21 of the connecting shaft 2 relative to the first through hole, and a clamping limiting piece is arranged in the clamping groove. In this way, after the high-pressure bin is connected with the collection bin through the flange plate 1, during the high-speed unloading process of the high-pressure gas in the high-pressure gas ore pulverizing device, when the high-pressure bin bears the reaction, the clamping limiting piece can limit the high-pressure bin, which can ensure the reliability of the connection between the high-pressure bin and the collection bin, reduce the risk of loosening of the connection between the high-pressure bin and the collection bin and leakage of the high-pressure gas in the high-pressure bin, and thus increase the reliability of the work of the high-pressure gas ore pulverizing device.

[0041] For example, the clamping limiting piece can be a clamping spring.

[0042] In order to increase the replaceability between the flange plate 1 and the connecting shaft 2, in an embodiment, the inner wall of the first through hole of the flange plate 1 is provided with an internal thread, the connecting part 21 of the connecting shaft 2 is provided with an external thread, and the external thread is threadedly connected with the internal thread.

[0043] In an embodiment, the connecting shaft 2 is in the shape of a truncated cone, the connecting part 21 is located at one end of the upper base of the connecting shaft 2, and the operating part 22 is located at one end of the lower base of the connecting shaft 2; the shape of the first through hole is matched with the shape of the connecting shaft 2.

[0044] The connecting principle and technical effect of the connecting shaft 2 and the first through hole are similar to those of the operating rod 3 and the connecting hole, and will not be described here.

[0045] Further, the connecting part 21 of the connecting shaft 2 is in the shape of a truncated cone, and the operating part 22 of the connecting shaft 2 is in the shape of a cylinder, and one end of the lower bottom surface of the connecting part 21 is connected to the connecting shaft 2.

[0046] In an embodiment, the flange plate 1 is in the shape of a circular truncated cone, and one end of the flange plate 1 close to the collecting bin of the high-pressure gas ore pulverizing device is the upper bottom surface.

[0047] The connecting part 21 of the collecting bin of the high-pressure gas ore pulverizing device comprises a connecting groove, and the shape of the connecting groove is matched with the shape of the flange plate 1. Thus, the connecting principle and technical effect of the flange plate 1 and the collecting bin are similar to those of the operating rod 3 and the connecting hole, and will not be described here.

[0048] In an embodiment, the high-pressure gas in the high-pressure gas ore pulverizing device can be high-pressure liquid carbon dioxide. In order to avoid damage to the locking device, the connecting shaft 2 and the operating rod 3 have corrosion resistance.

[0049] In an embodiment, the flange plate 1, the connecting shaft 2, and each operating rod 3 have corrosion resistance, so as to avoid corrosion and damage of the flange plate 1, the connecting shaft 2, and each operating rod 3 by the high-pressure gas in the high-pressure gas ore pulverizing device.

[0050] In an embodiment, the strength of the flange plate 1, the connecting shaft 2, and each operating rod 3 can avoid damage of the flange plate 1, the connecting shaft 2, and each operating rod 3 by the impact force generated by the release of the high-pressure gas.

[0051] In an embodiment, a sealing ring can be arranged at the connection between the connecting part 21 of the connecting shaft 2 and the first through hole of the flange plate 1. Thus, the sealing performance of the high-pressure bin and the collecting bin can be ensured, the resistance of the separation of the high-pressure bin and the collecting bin can be increased, and the structural stability of the high-pressure bin and the collecting bin can be ensured.

[0052] In an embodiment, the thread in each of the foregoing embodiments is a special thread, which can provide a more firm connection effect for the connection between the flange plate 1 and the collecting bin, the connection between the high-pressure bin and the connecting shaft 2, and the connection between the operating rod 3 and the connecting shaft 2. The specific parameters of the special thread can be determined according to the actual working conditions.

[0053] In an embodiment, the thread gap between the operating rod 3 and the connecting hole of the operating part 22 of the connecting shaft 2 can be adjusted to meet the needs and requirements of different high-pressure gas ore pulverizing devices.
