DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] An embodiment of the present application discloses a cooling structure of a kiln feeder.

[0032] Example 1

[0033] Reference Figure 1 A cooling structure of a kiln charging machine includes a cooling pipe 1, and the cooling pipe 1 includes a cooling section 11 and an external section 12. The kiln charging machine is provided with a receiving cavity, the cooling section 11 is installed in the receiving cavity, and the external section 12 is an external cooling medium, and the cooling medium can be water or salt water.

[0034] The cooling pipe 1 has an inlet 13 and an outlet 14. The inlet 13 is used for the cooling medium to enter the cooling pipe 1, and the outlet 14 is used for the cooling medium to flow out of the cooling pipe 1. When the feeder is working, the cooling medium is introduced into the cooling pipe 1 from the inlet 13, and the cooling medium flows through the cooling section 11 and then flows out from the outlet 14. Since the cooling medium is arranged in the accommodating cavity inside the frame, the frame of the feeder can be effectively cooled, thereby extending the service life of the feeder.

[0035] The cooling section 11 can be integrally formed with the peripheral section 12 to ensure the sealing performance of the cooling pipe 1; or the connection can be detachable to facilitate adaptation to various types of feeders.

[0036] Furthermore, in this embodiment, a one-way valve 2 is provided in the cooling pipe 1, and the one-way valve 2 is located in the cooling section 11. The one-way valve 2 is used to prevent the reverse flow of the cooling medium. The volume and pressure of the cooling medium increase at high temperature, which will form a reverse flow trend, thereby forming a certain obstruction to the flow of the low-temperature cooling medium introduced, resulting in a low efficiency and speed of the low-temperature cooling medium introduction; the one-way valve 2 forms a certain obstruction to the reverse flow of the high-temperature medium to ensure the introduction speed of the cooling medium and the cooling effect of the cooling section 11 on the feeder.

[0037] The implementation principle of Example 1 is as follows: a cooling pipe 1 is installed on the feeder, and a cooling medium is introduced into the cooling pipe 1 from the inlet 13, so that heat exchange is formed with the interior of the feeder when the feeder enters the kiln, and the feeder is cooled, thereby having a certain temperature control effect on the feeder and extending the service life of the feeder.

[0038] Example 2

[0039] Reference Figure 2 The difference between this embodiment and embodiment 1 is that a plurality of one-way valves 2 are provided, and the plurality of one-way valves 2 are arranged at intervals along the length direction of the cooling section 11, so that the inner cavity of the cooling pipe 1 is partitioned into multiple sections by utilizing the plurality of one-way valves 2, and multi-point barriers are formed for the high-temperature cooling medium, thereby further ensuring the introduction speed of the cooling medium and the cooling effect of the cooling section 11 on the feeder.

[0040] The cooling pipe 1 includes a conveying section 15 and a connecting section 16. The connecting section 16 is used to connect adjacent conveying sections 15. The connecting section 16 is detachably connected to the conveying section 15. The one-way valve 2 is arranged on the connecting section 16. When the cooling pipe 1 is produced, on the one hand, a shorter connecting section 16 is produced, and then the one-way valve 2 is welded to the connecting section 16. On the other hand, the conveying section 15 is produced, and then the connecting section 16 is connected to the conveying section 15. Therefore, on the one hand, it is convenient to set the one-way valve 2 in the cooling pipe 1, and on the other hand, it is convenient to flexibly control the length of the cooling pipe 1.

[0041] In this embodiment, the connecting section 16 and the conveying section 15 are detachably connected by a threaded connection. In other embodiments, the connecting section 16 and the conveying section 15 can also be connected by an interference sleeve.

[0042] Example 3

[0043] Reference Figure 3 The difference between this embodiment and embodiment 1 is that a plurality of cooling pipes 1 are provided, and the plurality of cooling pipes 1 are arranged at intervals along a defense line perpendicular to the axis thereof, so that the distribution of the cooling structure in the frame of the feeder is relatively uniform, thereby improving the cooling effect of the cooling structure.

[0044] In this embodiment, the cooling section 11 includes a first section 17, a second section 18 and a curved section. The first section 17 and the second section 18 are arranged in parallel, and the curved section is used to connect the first section 17 and the second section 18, that is, the cooling section 11 is arranged in a "U" shape. In this embodiment, the first section 17 is connected to the inlet 13, and the second section 18 is connected to the outlet 14, so the cooling medium flows through the first section 17, the curved section and the second section 18 in sequence, and the temperature gradually increases during the flow. Since the first section 17 and the second section 18 are arranged in parallel, when the cooling medium flows to the second section 18, it can exchange heat with the cooling medium in the first section 17. In addition, there are multiple cooling pipes 1, so the uniformity of the temperature distribution of the feeder can be ensured to a certain extent, and the service life of the feeder can be extended.

[0045] Furthermore, a heat conducting component 3 is provided between adjacent cooling tubes 1, and both ends of the heat conducting component 3 are respectively connected to the first section 17 and the second section 18 of the adjacent cooling tubes 1, so that the heat conducting component 3 is used to transfer heat to the first section 17 and the second section 18 of the adjacent cooling tubes 1, thereby further improving the temperature distribution uniformity of the feeder.

[0046] In this embodiment, the heat conducting assembly 3 includes a first screw 31, a second screw 32 and a threaded sleeve 33. The first screw 31 is used to connect with the first section 17, and the second screw 32 is used to connect with the second section 18 of the adjacent cooling pipe 1. The first screw 31 is threadedly connected with the threaded sleeve 33, and the second screw 32 is threadedly connected with the threaded sleeve 33. Thus, the first screw 31 and the second screw 32 are detachably connected, and then the adjacent cooling pipes 1 are detachably connected, ensuring the flexibility of use of the cooling structure.

[0047] The first screw rod 31 is fixed to the cooling tube 1 by welding, and the second screw rod 32 is fixed to the cooling tube 1 by welding.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
