New description: [New technical field] The present invention relates to a compressor, in particular to a multi-stage screw compressor. [Prior Art] In a conventional screw compressor, a male rotor and a female rotor are disposed in a compression chamber, and the respective spirals of the male and female rotors are coupled to each other to rotate to compress a medium (for example, air). The above compressor can adjust the output pressure by the loop design of the prime mover's rotation speed control, accumulator tank, pressure reducer, etc., but the maximum pressure of the output has a limit. If a medium higher than the maximum pressure output is required, a plurality of the above compressors are generally connected in series, and the pressurized medium output from the first compressor is sent to the second compressor and then pressurized, and then the second unit is placed. The pressurized medium output from the compressor is sent to a third compressor and then pressurized... to achieve the desired medium pressure. Although the above method can pressurize the medium to the required pressure, a plurality of compressors take up space and drive a plurality of compressors to consume energy, which is not an ideal method from the viewpoint of economy and environmental protection. [New content] In order to solve the above problems, the present invention provides a multi-stage screw compressor with fewer parts and smaller volume, with a simple combination of male and female spiral rotors, which improves the efficiency of the compression stroke, shortens the intermediate flow path, and reduces Pressure loss, reducing the loss of power transmission path, achieving a better compression balance force. 0 3 M406658 The multi-stage screw compressor of the present invention comprises at least a partition plate, a male rotor, a first female rotor, and a second female rotor. . The partition separates the compression chamber inside the compressor. The male rotor includes a revolving shaft disposed through the partition plate; a first spiral body coaxially disposed on the revolving shaft 'the compression chamber located on one side of the partition plate; and coaxially disposed on the revolving shaft and located at the partition of the partition plate A second spiral of the compression chamber on the other side. The first female rotor is located in one side of the compression chamber and is coupled to the first toroidal body. The second female rotor is located on the other side of the compression chamber and is coupled to the second spiral. In this case, the partition may comprise two baffle members, and the combination of the two baffle members encloses the revolving shaft. Further, the compression ratio of the one side compression chamber to the other side compression chamber may be the same or different. A lubricating mechanism may be disposed between the male rotor, the first female rotor, the second female rotor, and the partition, respectively, between the shaft t male rotor, the __ female rotor, the second female rotor, and the partition. [Embodiment] Fig. 1 is a perspective view showing an example of a multi-stage screw compressor of the present invention. The first ^ system! An exploded view of the multi-stage screw compressor of the drawing. Figure 1 shows a two-stage screw compressor. As shown in the exploded view of FIG. 2, the A rotor 100 is coaxially disposed on the revolving shaft 11〇 coaxially and closely disposed with the first spiral body 120 and the first spiral body J 3〇, coaxially moxiating to the same angle, and the first spiral body 120 and The second spiral 130 is located on the axis of the revolution shaft 110: the phase 2 position 'and the gap between the first spiral body 120 and the second spiral body 130 is accommodated to accommodate the thickness of the partition. The first female rotor 200 is coaxially disposed with the first female spiral body 220 on a mother shaft 210 of the M406658. The second female rotor 300 is coaxially disposed with the second female spiral body 320 on the second female rotating shaft 31. The partition plate 400 can be divided into a partition member A 400A and a partition member B 400B, and a male rotor shaft hole A 410A and a male rotor shaft hole B 410B are respectively formed at a corresponding assembly portion of the partition member A400A and the partition member B 400B. When the partition member A 400A is combined with the partition member B 400B, the male rotor shaft hole A 410 A and the male rotor shaft hole B 410B are combined into a male rotor shaft hole so that the male rotor 1 〇〇 can penetrate the partition plate 400 ° partition member A A first female rotor shaft hole 420 is disposed on the 400A, and a second female rotor shaft hole 430 is disposed on the partition member B 400B. The first female rotor shaft hole 420 and the second female rotor shaft hole 430 are disposed at the first position. The female spiral body 220 and the second female spiral body 320 may be respectively coupled to the first spiral body 120 and the second spiral body 130 and smoothly arranged. Inserting the spacer member A 400A and the spacer member B 400B ' into the gap between the first spiral body 120 and the second spiral body 130 with the male rotor shaft hole A410A and the male rotor shaft hole B 410B, and combining them into a male rotor shaft hole, and packaging The pinch shaft 110' is combined into a partition 400, and the compression chamber is partitioned into a first and second two-stage compression chamber, that is, the first spiral body 120 is located in the first-stage compression chamber, and the second spiral body 130 is located in the second-stage compression chamber. However, the first compression chamber and the second compression chamber are not airtightly separated, and the compressed medium can be circulated between the two compression chambers; in the case where the first female spiral 220 is sold with the first spiral 120, the first The female rotating shaft 210 is inserted into the first female rotor shaft hole 420, and the first female rotor 200 is disposed in the first stage compression chamber; and when the second female spiral body 320 is coupled to the second spiral body 130, the second female rotating shaft 310 is used. The second female rotor shaft hole 430 is inserted, and the second female rotor 300 5 is disposed in the second stage compression chamber. According to this, the structure shown in Fig. 1 is combined. The revolution shaft 110 is mechanically coupled to a prime mover (not shown) of the compressor, and drives the revolution shaft 110 with the prime mover to interlock the first spiral body 120 and the second spiral body 130 to rotate coaxially. At this time, the first female rotor 200 and the second female rotor 300, which are respectively coupled to the first spiral body 120 and the second spiral body 130, also rotate simultaneously. The pressing directions of the first-stage compression chamber and the second-stage compression chamber are in the same direction, that is, the compression medium is in the same direction of the pressurized flow in which the male rotor 100 is coupled to the first female rotor 200 and the second female rotor 300. The direction, for example, the medium is rotated by the male rotor 100 and the first female rotor 200, enters the first-stage compression chamber from outside the first-stage compression chamber, and is pressurized, and the medium pressurized by the first-stage compression chamber passes through The partition 400 enters the second stage compression chamber, and the male rotor 100 is rotated in meshing engagement with the second female rotor 300 to be pressurized to a higher pressure to output the second stage compression chamber. The compression ratio between the male rotor 100 and each of the female rotors can be freely set. For example, the compression ratio between the male rotor 100 and the first female rotor 200 is set to 2/1, and between the male rotor 100 and the second female rotor 300. When the compression ratio is also set to 2/1, ideally, the medium of one atmosphere is compressed in the first stage compression chamber by the compression ratio of 2/1 between the male rotor 100 and the first female rotor 200 to become two atmospheres. In the second-stage compression chamber, the two-atmospheric pressure medium is compressed in the second-stage compression chamber by the compression ratio of 2/1 between the male rotor 100 and the second female rotor 300 to be discharged into the second-stage compression chamber at four atmospheric pressures. Thus, the medium is pressurized to a predetermined pressure by the setting of the compression ratio in each section of the compression chamber. However, the actual output pressure is not leak-free as in the above ideal situation, so the compression ratio must be set in consideration of various leakages. The compression ratio of each of the pressure M406658 condensing chambers may be the same compression ratio as described above, or may be a different compression ratio.

Alternatively, the separator 400 may be separated into a plurality of separator members in any type in which the male rotor 100 may be sandwiched, and the separator 400 may be a single plate body, and the predetermined positions on the partition plate 4 respectively form the respective shafts. When the male rotor 100 is installed in the hole, the male sleeve 110 is inserted into the partition 400, and the first spiral 120 and the second spiral 13 are respectively inserted from the two ends of the male sleeve. In order to smoothly rotate, various types of bearings, lubrication mechanisms, and the like are disposed between the revolution shaft 110, the first female shaft 210, the second female shaft 31, and the partition 400, and are not described herein.
