[0002] With the improvement of scientific level, in daily life and work, in order to dry materials, dryers are often needed. A dryer refers to a mechanical device that uses heat energy to reduce the moisture content of materials and is used for drying objects. The dryer vaporizes and escapes the moisture (generally referring to moisture or other volatile liquid components) in the materials by heating to obtain solid materials with a specified moisture content. The purpose of drying is for the use or further processing of the materials. During the use of the dryer, the pipeline, as an important medium for gas circulation, is an essential part.
[0003] In the prior art, the pipelines of general combined dryers are mostly fixed by bolts. Although it can fix the pipelines and prevent the pipelines from displacing during transportation, in the prior art, the operation of fixing the pipelines is complex, which is not convenient for subsequent disassembly, assembly and maintenance of the pipelines. Moreover, in the prior art, gas backflow may occur during the drying process, affecting the drying effect. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to provide a pipeline installation structure for a combined dryer, which can effectively solve the problems that most of the pipeline installation structures in the prior art are complex in operation, not convenient for subsequent disassembly, assembly and maintenance of the pipelines, and gas backflow may occur during the drying process, affecting the drying effect, etc.
[0005] The technical solution adopted by the utility model is: a pipeline installation structure for a combined dryer, including a combined dryer, an inner connection component is fixedly installed on the top of the combined dryer, a one-way valve component is inserted and installed inside the inner connection component, an outer connection component is inserted and installed outside the inner connection component, a strip pipeline component is inserted and installed inside the outer connection component, and an arc pipeline component is inserted and installed on the strip pipeline component through the outer connection component.

[0007] Through the above technical solution, when installing the one-way valve assembly, the housing can be quickly aligned with the mounting seat by inserting the one-way valve assembly into the first limiting groove, preventing the housing from displacing in the horizontal direction, facilitating subsequent installation, and improving stability.
[0008] Preferably, the one-way valve assembly includes a housing, a first limiting ring, a second limiting block, a spring, a spherical block, and a second limiting ring.

The outer side of the inner pipe is closely attached to the inner side of the strip pipe. The fifth limiting block is inserted and installed with the inner side of the strip pipe.
[0013] Through the above technical solution, by providing an inner pipe, when installing the strip pipe assembly, inserting the fourth limiting block into the inner side of the strip pipe fixes the inner pipe inside the strip pipe, facilitating subsequent disassembly, assembly, and cleaning of the inner pipe, and extending the service life of the strip pipe assembly.
[0014] Preferably, the arc pipe assembly includes an arc-shaped pipe, a sixth limiting block, a sixth limiting groove, a fourth limiting hole, and a seventh limiting groove. The sixth limiting block is fixedly installed on the outer side of the arc-shaped pipe. The sixth limiting groove is formed on the outer side of the arc-shaped pipe. The fourth limiting hole is formed on the inner side of the sixth limiting groove. The seventh limiting groove is formed on the inner side of the arc-shaped pipe. The sixth limiting block is inserted and installed in the third limiting groove. The fourth limiting block is inserted and installed in the sixth limiting groove. The fifth limiting block is inserted and installed in the seventh limiting groove.
[0015] Through the above technical solution, through the cooperation of the fourth limiting block, the sixth limiting groove, the fifth limiting block, and the seventh limiting groove, the fourth limiting block is inserted into the sixth limiting groove, and at the same time, the fifth limiting block is inserted into the seventh limiting groove, so that the arc-shaped pipe and the strip-shaped pipe are quickly aligned and fixed, preventing the arc-shaped pipe and the strip-shaped pipe from displacing in the horizontal direction, improving the stability, facilitating subsequent installation. In cooperation with the fourth limiting block and the sixth limiting groove, the fourth limiting block is inserted into the sixth limiting groove, enabling the connecting sleeve to slide on the outer side of the arc-shaped pipe.
[0016] Preferably, the fourth limiting block is inserted and installed in the second limiting groove and the sixth limiting groove. The pin penetrates through the first limiting hole, the second limiting hole, and the third limiting hole and extends to the inner side of the mounting seat. The pin penetrates through the second limiting hole, the third limiting hole, and the fourth limiting hole and extends to the inner side of the arc-shaped pipe. The third limiting block is a plastic limiting block. One side of the third limiting block close to the fifth limiting groove is of an "arc" structure, and the third limiting block is adapted to the fifth limiting groove.
[0017] Through the above technical solution, by providing the fourth limiting block, the second limiting groove, and the sixth limiting groove, the fourth limiting block on one side is inserted into the second limiting groove, and the fourth limiting block on the other side is inserted into the sixth limiting groove. The connecting sleeves on both sides are slid to the designated positions. In cooperation with the pin, the first limiting hole, the second limiting hole, the third limiting hole, and the fourth limiting hole, one pin is inserted into the first limiting hole, the second limiting hole, and the third limiting hole and extends to the inner side of the mounting seat, and the other pin is inserted into the second limiting hole, the third limiting hole, and the fourth limiting hole and extends to the inner side of the arc-shaped pipe.

For the pipeline installation structure of the combined dryer, by setting the limit block four, limit slot two, limit slot six, plug, limit hole one, limit hole two, limit hole three and limit hole four, the connecting sleeve, strip pipe, arc pipe and mounting seat can be fixed without using bolts, which is convenient to operate, improves the overall stability and is also convenient for subsequent disassembly, assembly and maintenance.
[0020] 2. For the pipeline installation structure of the combined dryer, when the gas passes through the outer shell from bottom to top and the air pressure is greater than the force given by the spring to the spherical block, the spherical block moves upward, deforming the spring and allowing the gas to flow. When the gas passes through the outer shell from top to bottom, the spherical block is limited by the limit ring two and cannot move, so the gas cannot flow, avoiding gas backflow during the drying process and affecting the drying effect.

At this time, insert the fourth limiting block 502 into the sixth limiting groove 603, and at the same time insert the fifth limiting block 505 into the seventh limiting groove 605, so that the arc-shaped tube 601 and the strip-shaped tube 501 are quickly aligned and fixed.
