Abstract
The utility model provides a two-stage dry type oil-free screw compressor, which comprises a first-stage main machine, an intermediate cooler and a second-stage main machine, wherein the intermediate cooler comprises an air inlet, an air outlet and a condensing water separation blade; an exhaust port of the first-stage main machine is communicated with the air inlet; an air inlet of the second-stage main machine is communicated with the air outlet; and the exhaust port and the air inlet are positioned at the same side of the intermediate cooler. The two-stage dry type oil-free screw compressor has the beneficial effects that: the condensing water separation blade is arranged in the intermediate cooler, and thereby a connecting path between the first-stage main machine and the second-stage main machine is simplified and further the space occupied area of the compressor, the energy loss, the production cost and the weight of the machines are reduced.
Description
Technical field
The utility model relates to compressor, particularly a kind of two-stage dry type oil free screw compressor.
Background technique
At present, for the two-stage oil free screw compressor, it comprises one-level main frame, interstage cooler, condenswater separator and secondary main frame, interstage cooler and condenswater separator are two assemblies independently, and the relief opening of one-level main frame to interstage cooler, interstage cooler to condenswater separator, condenswater separator to secondary main frame all needs to use pipe arrangement to connect.At first, mode and pipe arrangement quantity are many owing to being linked in sequence, and cause the space hold of existing two-stage oil free screw compressor big; Secondly, because pipeline is long, elbow is many, increased the energy consumption of compressed-air actuated flow losses and compressor; At last, because pipe arrangement is many, the cost of material of compressor and the weight of machine have been increased.
The model utility content
In order to solve existing technical problem, the utility model provides a kind of two-stage dry type oil free screw compressor, it adopts and establishes the condensed water separator in the interstage cooler, thereby simplify the connecting path between one-level main frame and the secondary main frame, and then reduce space hold area, energy loss, cost of production and the machine weight of compressor.
The utility model solves existing technical problem, and a kind of two-stage dry type oil free screw compressor is provided, and it comprises one-level main frame, interstage cooler and secondary main frame; Described interstage cooler comprises air inlet, air outlet slit and condensed water separator; The relief opening of described one-level main frame is communicated with described air inlet, and the suction port of described secondary main frame is communicated with described air outlet slit, and described relief opening and described suction port are positioned at the same side of described interstage cooler.
The utility model further improves as described below.
The housing of described interstage cooler is double-deck sandwich structure.
Near described air outlet slit the condensed water separator is set.
Compared to prior art, the beneficial effects of the utility model are: adopt in the interstage cooler and establish the condensed water separator, thereby simplify the connecting path between one-level main frame and the secondary main frame, and then reduce space hold area, energy loss, cost of production and the machine weight of compressor.
Description of drawings
Fig. 1 is the principle schematic of the utility model two-stage dry type oil free screw compressor.
Fig. 2 is the cross-sectional schematic of described cooler.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further specified.
As depicted in figs. 1 and 2, a kind of two-stage dry type oil free screw compressor, it comprises one-level main frame 11, interstage cooler 12 and secondary main frame 13; Interstage cooler 12 comprises air inlet 121, air outlet slit 123 and condensed water separator 122; The relief opening 111 of one-level main frame 11 is communicated with air inlet 121, and the suction port 131 of secondary main frame 13 is communicated with air outlet slit 123, and relief opening 111 and suction port 131 are positioned at the same side of interstage cooler 12.Owing to establish condensed water separator 122 in the interstage cooler 12, realized pressurized air cooling and condensed moisture from integrated, separating of promptly compressed-air actuated cooling and condensed water can be finished simultaneously.On the whole, the pipeline compactness of pressurized air institute warp has reduced compressed-air actuated loss to greatest extent, has improved the efficiency of this compressor.Simultaneously, interstage cooler 12 easy for installation reduces a large amount of uses of pipe arrangement, saved assembly space.
The housing of the utility model interstage cooler 12 is double-deck sandwich structure, and under the situation of its air inlet 121 and air outlet slit 123 fixed-site, its heat exchange area still can be determined by actual demand, so that its heat exchange area is fully used like this.Simultaneously, near air outlet slit 123 condensed water separator 122 is set, promptly the cold junction at interstage cooler 12 is provided with condensed water separator 122, guarantees that the condensed water that pressurized air enters before the secondary main frame 13 wherein obtains separating, in order to avoid secondary main frame 13 is caused adverse effect.This compressor is in the process of work, pressurized air is walked shell side, condensed water is walked tube side, greatly makes things convenient for the maintenance of interstage cooler 12 and the cleaning of incrustation scale, and cleaning only need be opened the surperficial incrustation scale that the left and right sides end cap of interstage cooler 12 can exchange in the heat pipe during incrustation scale and directly be cleared up.
The utility model adopts in the interstage cooler 12 and establishes condensed water separator 122, thereby simplifies the connecting path between one-level main frame 11 and the secondary main frame 13, and then reduces space hold area, energy loss, cost of production and the machine weight of compressor.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
