Description

Technical Field

[0001] This utility model relates to the technical field of purification furnace equipment, and in particular to a descaling device for the air inlet cylinder of a high-temperature purification furnace. Background Technology

[0002] A high-temperature purification furnace, also known as a high-temperature graphitization furnace, is a device used for high-temperature treatment of materials. It is widely used in the graphitization of carbon fibers to transform the fiber structure into a graphite-like structure, as well as in the field of graphite purification to remove impurities through high temperatures.

[0003] In existing technologies, after each firing in a high-temperature purification furnace, a layer of scab forms on the inner wall of the air inlet cylinder. This scab is hard, has strong adhesion, and is very difficult to clean. Currently, it is usually removed bit by bit using a through screwdriver and a hammer, which is not only time-consuming and laborious, but also inefficient, and can easily damage the inner wall of the air inlet cylinder. In addition, the scab that is removed is not easy to clean. Utility Model Content

[0004] This application provides a descaling device for the air inlet cylinder of a high-temperature purification furnace. It can efficiently remove the scabbing inside the air inlet cylinder, extend the service life of the air inlet cylinder, and simultaneously suck away the removed scabbing, saving the trouble of additional cleaning and making it convenient to use.

[0005] This application provides a descaling device for the air inlet cylinder of a high-temperature purification furnace, including a rotating cylinder and a handle. The rotating cylinder has a descaling end and a driving end opposite to each other. The rotating cylinder has a cylinder cavity, and the descaling end has a slag inlet communicating with the cylinder cavity. The driving end is a closed structure for connecting a rotational power element. The handle is rotatably connected to the end of the rotating cylinder near the driving end via a rotary joint, allowing the rotating cylinder to rotate directionally relative to the handle. The rotary joint has a transition cavity, and the handle has a negative pressure slag suction channel along its extension direction. The negative pressure slag suction channel communicates with the cylinder cavity through the transition cavity. The end of the negative pressure slag suction channel away from the rotary joint is used to connect to the suction port of a negative pressure device.

[0006] In one possible implementation, the rotary power element is a handheld electric drill;

[0007] Alternatively, the rotary power element may be a fixed electric drill, and the hand grip may be connected to the fixed electric drill via a connecting bracket;

[0008] Alternatively, the rotating power element may be a suspended electric drill, which is suspended in the workshop by a rope, and the output shaft of the suspended electric drill is coaxially connected to the drive end.

[0011] In one possible implementation, the rotating cylinder has a junction port connecting the junction cavity and the cylinder cavity at a position opposite to the junction cavity, and the rotating cylinder is close to the center of the junction cavity.

[0012] In one possible implementation, the adapter has one or more interfaces, which are either unidirectionally distributed or circumferentially spaced.

[0013] In one possible implementation, the rotating cylinder has two annular sealing structures spaced axially at one end near the drive end, the rotary joint is installed between the two annular sealing structures, and bearings are provided in the rotary joint on both sides near the two annular sealing structures respectively. The outer side of the bearing is attached to the inner side of the annular sealing structure, and the inner ring of the bearing is fixedly sleeved on the rotating cylinder.

[0014] Beneficial effects: Compared with the prior art, the scab removal device for the high-temperature purification furnace air inlet provided in this application removes the scabs on the inner wall of the air inlet by the continuous rotation of the scab removal end on the rotating cylinder.

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0021] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0022] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0023] refer to Figures 1 to 4 This application provides a descaling device for the inlet cylinder of a high-temperature purification furnace, including a rotating cylinder 10 and a handle 20. The rotating cylinder 10 has a descaling end 11 and a driving end 12 opposite to each other. The rotating cylinder 10 is provided with a cylinder cavity 101, and the descaling end 11 is provided with a sludge inlet 102 communicating with the cylinder cavity 101. The driving end 12 is a closed structure for connecting a rotational power element. The handle 20 is rotatably connected to the rotating cylinder 10 near the driving end via a rotary joint 30. One end of 12 allows the rotating cylinder 10 to rotate relative to the handle 20 in a specific direction. Meanwhile, the rotating joint 30 is provided with a transition cavity 301, and the handle 20 is provided with a negative pressure suction channel 201 along its extension direction. The negative pressure suction channel 201 is connected to the cylinder cavity 101 through the transition cavity 301. The end of the negative pressure suction channel 201 away from the rotating joint 30 is used to connect to the suction port of the negative pressure device, so that the negative pressure device can provide a continuous negative pressure environment to the negative pressure suction channel 201.

[0024] Specifically, the negative pressure device can be a vacuum cleaner, and the vacuum cleaner's suction port is connected to the outer port of the negative pressure suction channel 201.

[0025] The rotating power element can be a handheld electric drill. During operation, the operator holds the handle 20 with one hand and the rotating power element with the other, and stands on the large graphite disc with both hands to perform the scab removal and suction work.

[0026] In addition, the rotating power element can also be a fixed electric drill. The hand grip 20 is connected to the fixed electric drill through a connecting frame, which is equivalent to fixing the body of the fixed electric drill to the hand grip. The rotating shaft of the fixed electric drill is coaxially connected to the drive end 12, and the operator can operate it by gripping the hand grip with one hand or both hands.

[0027] Alternatively, the rotary power element can also be a suspended electric drill, which is connected to the workshop by a rope in a suspended manner. At the same time, the output shaft of the suspended electric drill is coaxially connected to the drive end 12, which can save the weight of the rotary power element and make the operation easier.

[0028] The working principle is as follows: The handle 20 provides a handheld function and can control the specific scab removal position of the scab removal end 11 on the rotating cylinder 10, which is convenient for precise scab removal. The rotating cylinder 10 rotates continuously, and the scabs on the inner wall of the air inlet are chiseled off through the scab removal end 11. Since the cylinder cavity 101 has a continuous negative pressure adsorption environment, the removed scabs are sucked into the cylinder cavity 101 through the scab inlet 102 of the scab removal end 11. Then, they are transferred to the outside through the cylinder cavity 101, the transfer cavity 301 and the negative pressure suction channel 201, such as to the vacuum cleaner. In this way, automatic scab removal can be achieved, which is highly efficient and does not require separate cleaning of scabs, making it easy to operate.

[0029] In one embodiment, the descaling end 11 is inlaid with a diamond abrasive head 111, which enables the descaling device to remove scabs more efficiently and quickly, while also having a long service life.

[0030] In one embodiment, the rotating cylinder 10 is provided with a transition interface 103 connecting the transition cavity 301 and the cylinder cavity 101 at a position directly opposite the transition cavity 301. At the same time, the rotating cylinder 10 is close to the center of the transition cavity 301, so that no matter how the rotating cylinder 10 rotates, the scab in the cylinder cavity 101 can enter the transition cavity 301 through the transition interface 103, and then be discharged to the outside through the negative pressure sludge suction channel 201.

[0031] In one embodiment, the adapter 103 has one or more interfaces, and the adapter 103 is either unidirectionally distributed or circumferentially spaced.

[0032] In one embodiment, the rotating cylinder 10 has two annular sealing structures 121 spaced axially at one end near the drive end 12. The rotary joint 30 is installed between the two annular sealing structures 121, and bearings 31 are respectively provided on both sides near the two annular sealing structures 121 inside the rotary joint 30. The inner rings of the bearings 31 are fixedly sleeved on the rotating cylinder 10. Thus, the annular sealing structures 121 can serve a positioning and sealing function. The positioning function facilitates the quick and accurate installation of the rotary joint 30. More specifically, the housings of the rotary joint 30 are respectively pressed against the annular sealing structures. On 121, the two slide together, and the outer side of the bearing 31 is attached to the inner side of the annular sealing structure 121. The sealing effect can ensure the sealing environment of the transfer cavity 301, making it less prone to air leakage, thereby ensuring the reliability of the negative pressure in the cylinder cavity 101. In addition, the bearings 31 on both sides of the rotary joint 30 can ensure that the rotating cylinder 10 and the handle 20 maintain relative rotational movement. Since the negative pressure environment is transmitted through the negative pressure suction channel 201, the scab removed by the scab removal end 11 will travel in a directional manner through the cylinder cavity 101, the transfer interface 103, the transfer cavity 301 and the negative pressure suction channel 201, and will not easily affect the bearing 31.

[0033] It should be noted that the terms "first" and "second" used in this application are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
