Description

Technical Field

[0001] The utility model relates to an intermediate transition device which is convenient for installing an inner pipe of an air lift, belonging to the technical field of electrolytic aluminum. Background Art

[0002] A dilute-phase conveying system, especially a negative-pressure dilute-phase pneumatic conveying system, is an efficient material conveying method. This system mainly uses a gas with a certain flow rate to suspend solid powder materials in a conveying pipeline and transports the materials to a receiving point through the movement of the gas.

[0003] As Figure 5 shown, after long-term use, the middle-section pipeline is prone to serious wear, and the pipeline wall is easily damaged, resulting in problems in material lifting and environmental protection out of control. After problems occur, it directly affects production and reduces the quality of transported fluorine materials.

[0004] In the process of implementing the technical solution of the present application, the inventor found that there are at least the following technical problems in the prior art:

[0005] Due to the narrow internal space of the air lift, usually only one operator can perform maintenance. After the pipeline ruptures, it is not convenient to repair. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an intermediate transition device which is convenient for installing an inner pipe of an air lift, is convenient for replacement and operation.

[0007] The intermediate transition device which is convenient for installing an inner pipe of an air lift according to the utility model includes a transition pipeline. A sliding mounting sleeve is installed at the upper end of the transition pipeline. The lower end of the transition pipeline is slidably connected with an adjusting pipeline. An annular protrusion is arranged on the lower end surface of the transition pipeline;

[0008] An elastic sleeve that can move up and down is sleeved on the adjusting pipeline. When the elastic sleeve abuts against the upper annular protrusion, a matching locking mechanism is installed outside the elastic sleeve. The locking mechanism can press the elastic sleeve onto the adjusting pipeline and lock the transition pipeline and the adjusting pipeline together through the annular protrusion.

[0009] Further, a buckling cover arranged downward is provided at the lower end of the adjusting pipeline.

[0010] Further, the buckling cover is arranged in a columnar shape, and an elastic pad is attached to the upper end surface inside the buckling cover.

[0011] Further, the locking mechanism is a clamp.

[0012] Further, the diameter of the annular protrusion is at least 10 mm smaller than the diameter of the elastic sleeve.

[0013] Further, the sliding installation sleeve includes a sliding support plate provided at the upper end of the transition pipeline. A sealing gasket is installed on the sliding support plate, and a fixing plate is provided at the upper end of the sliding support plate.

[0014] Both the transition pipeline and the adjustment pipeline are ceramic-lined steel pipes.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] The present utility model simplifies the maintenance process, improves the replacement efficiency, and reduces the operation difficulty. Through the design of the sliding installation sleeve and the adjustment pipeline, during maintenance or replacement, the upper end can be directly slid and installed through the sliding installation sleeve. After inserting the adjustment pipeline into the lower connecting pipe, it can be directly locked through the elastic sleeve in cooperation with the locking mechanism. This design not only reduces the maintenance cost but also improves the production efficiency. At the same time, by using ceramic-lined steel pipes as the materials for the transition pipeline and the adjustment pipeline, the wear resistance and service life of the device are improved, and the maintenance cost is further reduced.

[0029] Embodiment 1

[0030] As Figures 1 to 4As shown in the figure, the internal pipe of the air-lift of the present utility model facilitates the installation of an intermediate transition device, including a transition pipe 2. A sliding mounting sleeve 1 is installed at the upper end of the transition pipe 2. The lower end of the transition pipe 2 is slidably connected to an adjustment pipe 4. An annular protrusion 21 is provided on the lower end face of the transition pipe 2;

[0031] An elastic sleeve 6 that can move up and down is sleeved on the adjustment pipe 4. When the elastic sleeve 6 abuts against the upper annular protrusion 21, a locking mechanism 3 adapted to the outside of the elastic sleeve 6 is installed. The locking mechanism 3 can press the elastic sleeve 6 onto the adjustment pipe 4, and through the annular protrusion 21, the transition pipe 2 and the adjustment pipe 4 are locked together.

[0032] A buckle cover 5 arranged downward is provided at the lower end of the adjustment pipe 4, so that the sealing between the adjustment pipe 4 and the connecting pipe at the lower end is better.

[0033] The buckle cover 5 is arranged in a column shape. An elastic pad 51 is attached to the upper end face inside the buckle cover 5. The elastic pad 51 can be made of a rubber pad.

[0034] The locking mechanism 3 is a clamp.

[0035] The diameter of the annular protrusion 21 is at least 10 mm smaller than the diameter of the elastic sleeve 6, ensuring the locking effect of the elastic sleeve 6 and avoiding interference caused by the annular protrusion 21.

[0036] The sliding mounting sleeve 1 includes a sliding support plate 11 provided at the upper end of the transition pipe 2. A sealing gasket 12 is installed on the sliding support plate 11. A fixing plate 13 is provided at the upper end of the sliding support plate 11. The sealing gasket 12 is a polytetrafluoroethylene gasket.

[0037] Both the transition pipe 2 and the adjustment pipe 4 are ceramic-lined steel pipes, with better wear resistance.

[0038] Working process or working principle:

[0039] After sliding the sliding mounting sleeve 1 in from the upper end and fixing it with screws 14, after the fixing is completed, lower the lower adjustment pipe 4 so that the connecting pipe at the lower end abuts against the elastic pad 51. At this time, lock it through the locking mechanism 3. After locking, fix the adjustment pipe 4 to the transition pipe 2.

[0040] In the present utility model, the description of the direction and relative position relationship of the structure, such as the description of front, back, left, right, up, and down, does not constitute a limitation to the present utility model, but is only for the convenience of description.
