Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing equipment technology, and more specifically to a top-mounted fan guide assembly for a gas-liquid separation dyeing machine. Background Technology

[0002] In existing gas-liquid separation dyeing machines, i.e., gas-liquid dyeing machines, the airflow generated by the circulating fan propels the fabric to move at high speed in the dyeing tank, replacing the traditional mechanical agitation method.

[0003] However, existing circulating fans are generally side fans, which are installed on one side of the main tank. Different fans are needed depending on the different flow pipelines, resulting in a wide variety of types and a large floor area required.

[0004] Some circulating fans are installed at the top center of the main tank, between two fabric lifting pipes. Two outlets are directly connected to the fan casing, and these outlets connect to the inlets on the side walls of the corresponding fabric lifting pipes. Because the circulating fan is located at the top center of the main tank, it increases the height of the gas-liquid separation dyeing machine. In some production areas, the height of the gas-liquid separation dyeing machine is limited by space constraints; an excessively high height would affect the maintenance space above the machine. Therefore, with this design, only a thinner type of fan can be used. Thin fans have limited motor options, generally preventing the use of high-power motors, which affects the output airflow. Simultaneously, the two outlets of the fan casing cannot effectively form static pressure, resulting in inefficient performance. That is, the air drawn in through the two outlets cannot circulate and pressurize within the fan casing; instead, it is immediately output after entering, failing to achieve the required pressure. This affects fabric conveying, resulting in poor performance and inefficient operation. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a top-mounted fan guide assembly for a gas-liquid separation dyeing machine. It is located behind the top plate of the main tank, which is cylindrical. The top-mounted fan can be installed at a lower position, thereby allowing for the installation of a more powerful fan to meet the usage requirements. Moreover, its volute has only a single air outlet, which allows the incoming air to form a stable air pressure in the volute and ensures that the air pressure entering the two fabric lifting pipes is large enough to meet the usage requirements.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A top-mounted fan guide assembly for a gas-liquid separation dyeing machine includes a main tank. Fabric lifting pipes are installed on the left and right sides of the middle part of the top of the main tank. The front end and rear end of the fabric lifting pipes are respectively connected to the outlet end of an inlet guide pipe and the inlet end of an outlet guide pipe. The inlet end of the inlet guide pipe and the outlet end of the outlet guide pipe are connected to the main tank.

[0008] A horizontally placed top fan is installed above the main tank between the two fabric lifting pipes. A collecting air guide pipe is installed between the middle of the two fabric lifting pipes, and the air outlets at both ends of the collecting air guide pipe are connected to the two fabric lifting pipes.

[0009] The air outlet of the top-mounted fan is connected to the air inlet connecting pipe that is connected to the middle rear wall of the air collection duct.

[0010] The front side plates at both ends of the air collection duct are tapered side plates that extend obliquely backward to both ends.

[0011] The top-mounted fan is a centrifugal fan, and its volute has a forward-extending concentrating pipe at the air outlet end. The flange at the front air outlet end of the extended concentrating pipe is fixedly connected to the flange at the rear air inlet end of the air inlet connecting pipe by bolts.

[0012] The air inlet of the top-mounted fan is located in the middle of the bottom plate of the volute. A lower connecting pipe is fixed in the middle of the bottom surface of the bottom plate of the volute. The upper end of the lower connecting pipe is connected to the air inlet of the volute, and the lower end of the lower connecting pipe is fixed to the top of the main air inlet pipe fixed on the top plate of the main tank.

[0013] The middle part of the main air inlet pipe is inserted into a through hole formed on the top plate of the main tank. The outer wall of the middle part of the main air inlet pipe is welded and fixed to the inner wall of the through hole. The upper end of the main air inlet pipe extends out of the top surface of the top plate of the main tank and the lower end of the main air inlet pipe extends into the main tank.

[0014] The top-mounted fan is located above the main tank at the rear between the two fabric lifting pipes;

[0015] The bottom surface of the bottom plate of the volute of the top-mounted fan is fixed with multiple supporting connecting columns, and the bottom end of the supporting connecting columns is fixed to the top surface of the top plate of the main tank.

[0016] The outstanding effect of this utility model is:

[0017] It is located behind the top plate of the main tank, which is cylindrical. The top-mounted fan can be installed at a lower position, allowing for the installation of a more powerful fan to meet the usage requirements. Moreover, its volute has only a single air outlet, which ensures that the incoming air forms a stable air pressure in the volute and guarantees that the air pressure entering the two fabric lifting pipes is large enough to meet the usage requirements.

[0023] For example, see below. Figures 1 to 5 As shown, a top-mounted fan guide assembly for a gas-liquid separation dyeing machine includes a main tank 10. Fabric lifting pipes 20 are installed on the left and right sides of the top middle part of the main tank 10. The front end and rear end of the fabric lifting pipes 20 are respectively connected to the outlet end of the inlet guide connecting pipe 21 and the inlet end of the outlet guide connecting pipe 22. The inlet end of the inlet guide connecting pipe 21 and the outlet end of the outlet guide connecting pipe 22 are connected to the main tank 10.

[0024] A horizontally placed top-mounted fan 30 is installed above the main tank 10 between the two fabric lifting pipes 20. Figure 1 (The impeller of the blower is not shown). A flow-collecting guide pipe 40 is provided between the middle of the two fabric lifting pipes 20. The air outlets at both ends of the flow-collecting guide pipe 40 are connected to the side connectors welded and fixed to the middle side walls of the two fabric lifting pipes 20. The side connectors are connected to the fabric lifting pipes 20.

[0025] The air outlet of the top-mounted fan 30 is connected to the air inlet connecting pipe 41 that is connected to the middle rear wall of the collecting air duct 40;

[0026] The front side plates at both ends of the air collection duct 40 are tapered side plates 42 that extend obliquely backward to both ends.

[0027] Furthermore, the top-mounted fan 30 is a centrifugal fan, and its volute has an extended concentrating pipe 31 extending forward at the air outlet end. The flange at the front air outlet end of the extended concentrating pipe 31 is fixedly connected to the flange at the rear air inlet end of the air inlet connecting pipe 41 by bolts, and a sealing ring is clamped between the two flanges.

[0028] The top-mounted fan 30 is located above the main tank 10, behind the two fabric lifting pipes 20;

[0029] The bottom surface of the bottom plate of the volute of the top-mounted fan 30 is fixed with multiple supporting connecting columns 1, and the bottom end of the supporting connecting columns 1 is fixed to the top surface of the top plate of the main tank 10.

[0030] In this embodiment, since the top-mounted fan 30 is located above the main tank 10 behind the two fabric lifting pipes 20, and the cross-section of the main tank 10 is circular, the height of the top-mounted fan 30 can be reduced during installation, so a thicker top-mounted fan 30 can be used, and a more powerful top-mounted fan 30 can be equipped for use without making the overall height of the equipment excessively high.

[0031] Secondly, its top-mounted fan 30 is a centrifugal fan, and its volute has only one air outlet end. Therefore, after the air enters, it can circulate almost once in the entire volute, achieving deceleration and pressurization. Then, it passes through the collecting air guide pipe 40. The front side plates at both ends of the collecting air guide pipe 40 are tapered side plates 42 that extend obliquely backward to both ends. This can further concentrate the gas discharged from the left and right ends of the collecting air guide pipe 40, making the air discharge more concentrated and the air pressure greater. This satisfies the function of the fabric lifting pipe 20 for air intake and fabric guidance, and meets the needs of fabric circulation dyeing. Its effect is obvious.

[0032] Furthermore, the air inlet of the top-mounted fan 30 is located in the middle of the bottom plate of the volute. A lower connecting pipe 32 is fixed in the middle of the bottom surface of the bottom plate of the volute. The upper end of the lower connecting pipe 32 is connected to the air inlet of the volute, and the lower end of the lower connecting pipe 32 is fixed to the top of the main air inlet pipe 50 fixed on the top plate of the main tank 10.

[0033] The middle part of the main air inlet pipe 50 is inserted into a through hole formed on the top plate of the main tank 10. The outer side wall of the middle part of the main air inlet pipe 50 is welded and fixed to the inner side wall of the through hole. The upper end of the main air inlet pipe 50 extends out of the top surface of the top plate of the main tank 10, and the lower end of the main air inlet pipe 50 extends into the main tank 10.

[0034] The main body of the main air inlet duct 50 is a horizontally extending duct section, with an upwardly extending and bent upper end at its rear end and a downwardly extending and bent lower end at its front end.

[0035] A filter screen 51 is fixed at the air inlet at the lower end of the main air inlet duct 50, and the filter screen 51 covers the air inlet at the lower end of the main air inlet duct 50.

[0036] The filter screen 51 has multiple air-permeable holes formed on its surface. The filter screen 51 is fixedly connected by bolts.

[0037] It can filter particles or some filamentous impurities in the intake gas through the filter screen 51, so that they will not enter the top fan 30, ensuring the normal operation of the equipment.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
