Description

Technical Field

[0001] The utility model relates to the technical field of reversing valves, in particular to an installation structure of a reversing valve of a dryer. Background Art

[0002] In the pharmaceutical, food, chemical and other industries, materials often need to be dried. A desiccant dryer is a device that uses the principle of air flow to evaporate the moisture adsorbed on the surface of the material. In order to direct the gas flow to different locations or equipment in the desiccant dryer, a reversing valve is often required. In the desiccant dryer, the reversing valve is usually used to control the flow direction of hot air or dry gas in order to dry the material.

[0003] China Utility Model Patent Publication No.: CN 216478103 U, discloses: a reversing valve for a dryer, which, when in use, can quickly lock and fix the locking clamp by rotating the locking nut and the locking screw, making it more convenient to install and disassemble the design with the pipeline, and making subsequent maintenance and repair simpler. However, the reversing valve for the dryer needs to use tools such as wrenches to lock the nuts and screws, which is more complicated to operate and inconvenient for subsequent disassembly and maintenance of the pipeline. Moreover, the reversing valve for the dryer is not designed with a filtering structure. When raw materials such as liquid or gas enter the interior of the dryer, it is easy to contain more impurities, which not only easily affects subsequent processing, but also easily causes impurities to be adsorbed to the inner wall of the pipeline, causing blockage, which is not convenient for subsequent cleaning. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide an installation structure for a reversing valve of a dryer, which can effectively solve the problems in the prior art that the operation is relatively complicated, the subsequent disassembly and maintenance of the pipeline is inconvenient, and impurities are easily adsorbed to the inner wall of the pipeline, causing blockage and inconvenience for subsequent cleaning.

[0005] The technical scheme adopted by the utility model is: a mounting structure of a reversing valve of a dryer, comprising a reversing valve and a dryer, a limiting hole is provided on the right side of the reversing valve, a cylinder is fixedly installed on the reversing valve near the right side of the limiting hole, a connecting shaft is fixedly installed on the output end of the cylinder, a limiting column is fixedly installed on the outer side of the connecting shaft, an air hole is provided on one side of the reversing valve, an air hole is provided on the other side of the reversing valve, a limiting groove is provided on the inner side of the reversing valve, pipeline components are fixedly installed on both sides of the reversing valve, a mounting frame is plugged and installed on the bottom of the reversing valve, and a limiting groove is provided on the top of the mounting frame;

[0006] The pipeline assembly includes pipeline 1, limiting groove 2, limiting groove 3, pipeline 2, limiting groove 4, limiting column 2, knob, limiting block 1, spring, limiting block 2, limiting groove 5, limiting column 3, limiting groove 6 and filter. Pipe 1 is fixedly installed on both sides of the reversing valve. The outer edge of the top of the pipeline 1 is provided with limiting groove 2, and the bottom of the limiting groove 2 is provided with limiting groove 3. The top of the pipeline 1 is provided with pipeline 2, and the outer edge of the bottom of the pipeline 2 is provided with limiting groove 4.

The top of the limiting block 2 is provided with limiting groove 5, and the bottom of the limiting column 2 is fixedly installed with limiting column 3. The inner edge of the top of the pipeline 1 is provided with limiting groove 6, and the inner side of the limiting groove 6 is provided with a filter.

[0007] Preferably, a mounting frame is fixedly installed on the top of the desiccant machine, and the limiting groove seven and the reversing valve are installed by plugging.

[0008] Through the above technical solution, when installing the mounting frame, the reversing valve can be fixed to the inner side of the mounting frame by inserting the bottom of the reversing valve into the limiting groove seven, which is easy to operate and convenient for subsequent disassembly, assembly and maintenance.

[0009] Preferably, the output end of the cylinder and the connecting shaft pass through the limiting hole and extend to the inner side of the limiting groove 1, and the limiting groove 1 and the limiting column 1 are slidably connected.

[0010] Through the above technical solution, when using the reversing valve, by starting the cylinder, the output shaft of the cylinder can drive the connecting shaft to move back and forth on the inner side of the limit groove 1, thereby causing the limit column 1 to move back and forth on the inner side of the limit groove 1, which is easy to operate.

[0011] Preferably, the diameter of the connecting shaft is smaller than the diameter of the limiting column one, the air hole one, the air hole two and the limiting groove one are connected to each other, the length of the limiting column one is larger than the diameters of the air hole one and the air hole two, and the air hole one is provided with two identical ones.

[0012] Through the above technical solution, through the cooperation of air hole 1, air hole 2 and limiting groove 1, the gas can enter and exit through air hole 1 and air hole 2, and circulate with the help of limiting groove 1. When the limiting column 1 moves and blocks the limiting groove 1 between air hole 1 and air hole 2 on one side, the gas in air hole 1 and air hole 2 on the other side circulates.

[0015] Preferably, the limiting column three is adapted to the limiting groove two and the limiting groove four, and the limiting column two passes through the limiting groove four and the limiting groove two and extends to the bottom thereof.

[0016] Through the above technical scheme, by cooperating with the limiting column three and the limiting groove two and the limiting groove four, the limiting column two can be quickly positioned, so that when fixing the pipe one and the pipe two, the limiting column two can be quickly inserted into the limiting groove two and the limiting groove four and extended to the bottom of the limiting groove two, so as to fix the pipe one and the pipe two, so that the limiting column two will not be offset in the horizontal direction, thereby improving stability.

[0017] Preferably, the limiting column three is matched with the limiting groove three, and a spring is arranged between the limiting block one and the limiting block two.

[0018] Through the above technical solution, after the limit column 2 is inserted into the limit groove 2 and the limit groove 4 and extends to the bottom of the limit groove 2, by pressing the knob, the limit block 1 moves downward on the inner side of the limit groove 5, and the limit column 2 drives the limit column 3 to move downward to the bottom of the limit groove 2. At this time, the knob is twisted to make the limit column 3 rotate at the bottom of the limit groove 2. When it is rotated 90°, the knob is released, and under the reaction force of the spring, the limit block 1 moves upward on the inner side of the limit groove 5 and resets. At this time, the limit column 3 is located on the inner side of the limit groove 3, so that the limit column 2 will not be offset in the vertical direction, which is convenient for operation and further improves the stability of pipes 1 and 2.

[0036] Embodiment 2: Figure 2-6 As shown, as an improvement to the previous embodiment.

[0037] Specifically, the number of pipeline components 9 corresponds to the number of air holes 1 6 and air holes 2 7, and pipeline 1 901 is connected with air holes 1 6 and air holes 2 7. The advantage is that by setting pipeline 1 901 and filter 914, gas can be transported through pipeline 1 901, air holes 1 6 and air holes 2 7.

The advantage is that the limiting column three 912 cooperates with the limiting groove two 902 and the limiting groove four 905, so that the limiting column two 906 can be quickly positioned, so that when fixing the pipe one 901 and the pipe two 904, the limiting column two 906 can be quickly inserted into the limiting groove two 902 and the limiting groove four 905 and extend to the bottom of the limiting groove two 902, thereby fixing the pipe one 901 and the pipe two 904, so that the limiting column two 906 will not be offset in the horizontal direction, thereby improving stability.

[0039] Specifically, the limiting column 3 912 is adapted to the limiting groove 3 903, and a spring 909 is provided between the limiting block 1 908 and the limiting block 2 910. The advantage is that after the limiting column 2 906 is inserted into the limiting groove 2 902 and the limiting groove 4 905 and extended to the bottom of the limiting groove 2 902, by pressing the knob 907, the limiting block 1 908 moves downward on the inner side of the limiting groove 5 911, and the limiting column 2 906 drives the limiting column 3 912 to move downward to the bottom of the limiting groove 2 902.

[0040] Working principle: When in use, insert the reversing valve 1 into the limiting groove 7 11 so that the reversing valve 1 can be fixed on the top of the mounting frame 10, then insert the filter screen 914 into the limiting groove 6 913, and make the bottom of the pipe 2 904 abut against the top of the pipe 1 901, and make the limiting groove 2 902 overlap with the limiting groove 4 905, and then insert the limiting column 2 906 into the limiting groove 2 902 and the limiting groove 4 905 and extend to the bottom of the limiting groove 2 902, and then press the knob 907 to make the limiting block 1 908 move downward on the inner side of the limiting groove 5 911, and the limiting column 2 906 drives the limiting column 3 912 to move downward to the bottom of the limiting groove 2 902, and then twist the knob 907 to make the limiting column 3 912 rotate at the bottom of the limiting groove 2 902. When the knob 907 is rotated, the limiting column 3 912 rotates at the bottom of the limiting groove 2 902. When the position is 0°, the knob 907 is released, and the limit block 908 moves upward and resets on the inner side of the limit groove 5 911 under the reaction force of the spring 909. At this time, the limit column 3 912 is located on the inner side of the limit groove 3 903, so that the limit column 2 906 will not be offset in the vertical direction. When the pipe 1 901 and the pipe 2 904 are fixed, by starting the cylinder 3, the output shaft of the cylinder 3 can drive the connecting shaft 4 to move back and forth on the inner side of the limit groove 8. When the limit column 1 5 moves and blocks the air hole 1 6 or the air hole 2 7, the gas stops flowing. When the limit column 1 5 moves and blocks the limit groove 1 8 between the air hole 1 6 and the air hole 2 7 on one side, the gas in the air hole 1 6 and the air hole 2 7 on the other side flows and is transported with the help of the pipe 1 901 and the pipe 2 904.
