Description

Technical Field

[0001] The present invention relates to a compressor.

Background Art

[0002] There is a compressor in which a compressor main body and a tank for storing compressed air discharged from the compressor main body are provided in a housing (see Patent Document 1). In the tank of such a compressor, water called drain water, that is, water formed by cooling the compressed gas and condensing water vapor in the air, accumulates. The water accumulated in the tank may cause problems such as rusting of the tank. In addition, when the tank is filled with drain water, there is also a risk that moisture may enter the compressor main body and other devices, causing malfunctions and accidents. Therefore, it is necessary to periodically discharge the water accumulated in the tank. The compressor described in Patent Document 1 is provided with a discharge device for discharging drain water in the tank, and a sound-absorbing water supply member such as a sponge is provided near the discharge port of the discharge device.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The compressor described in Patent Document 1 can cause the drain water accumulated in the tank as a gas storage tank to be absorbed by the sound-absorbing water supply member. However, when the absorbed and accumulated water exceeds a predetermined amount, the sound-absorbing water supply member cannot absorb more water. For this reason, it is necessary to periodically remove the sound-absorbing water supply member from the compressor and discard the water accumulated in the sound-absorbing water supply member. Thus, the operation of discharging the drain water as a liquid accumulated in the gas storage tank in the compressor has room for improvement in that the operation is complicated and time-consuming, especially in a facility equipped with a plurality of compressors.

[0005] An object of the present invention is to provide a compressor that facilitates the discharge process of liquid accumulated in a gas storage tank. [Means for solving the problem]

[0006] In order to solve the above problems, the compressor of the present invention includes a housing, a compressor main body, a gas storage tank, a discharge flow path, a liquid discharge portion, and a liquid storage chamber. The housing forms an outer shell. The compressor main body compresses gas. The gas storage tank stores compressed gas discharged from the compressor main body. The discharge flow path is a flow path that discharges liquid from the gas storage tank. The liquid discharge portion is provided at the downstream end of the discharge flow path and discharges the liquid by diffusing it in a fan shape. A liquid absorbing member that receives the liquid discharged from the liquid discharge portion is arranged in the liquid storage chamber. Air flowing within the housing passes from the periphery of the compressor body through the cooling chamber and is sent toward the liquid-absorbing member. The housing contains the compressor body, the gas storage tank, the cooling chamber, The discharge channel, the liquid discharge portion, and the liquid storage chamber are provided. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a compressor that facilitates the discharge process of liquid accumulated in a gas storage tank. [Brief explanation of the drawings]

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the accompanying drawings. In each drawing, the same or similar components are denoted by the same reference numerals, and redundant explanations thereof will be omitted as appropriate.

[0010] Fig. 1 is a perspective view of a compressor 100 according to an embodiment of the present invention. Fig. 2 is a left side view of the compressor 100 shown in Fig. 1. For convenience of explanation, up, down, left, right, front and rear directions are set as shown in Fig. 1. 1, the compressor 100 includes a housing 1 that forms an outer shell. The housing 1 includes a front panel 4, a top panel 5, a rear panel 9 (see FIG. 2), a right panel 6, a left panel 8 (see FIG. 2), and a base 2.

[0011] Compressor 100 is a package-type compressor configured by arranging main components such as compressor main body 11 (see FIG. 3) in housing 1. An operation panel 3 for receiving user operations and displaying various information is provided on the front face (front surface) of compressor 100. In addition, as shown in FIG. 2, an air intake port 8A for drawing outside air into housing 1 is provided on left side panel 8.

[0012] 3 is a cross-sectional view taken along line III-III in FIG. 1, FIG. 4 is a cross-sectional view taken along line IV-IV in FIG. 1, and FIG. 5 is a cross-sectional view taken along line VV in FIG. As shown in Figures 3 and 4, the housing 1 contains a compressor body 11, an air tank 12, a discharge flow path 33A (see Figure 4), diffusion nozzles 21A and 21B, a liquid storage chamber 10, and a cooling chamber 17 (see Figure 4).

[0013] As shown in FIG. 4, a pedestal 15 is attached to the base 2 via vibration-isolating rubber 16. A compressor main body 11 and an air tank 12 serving as a gas storage tank are attached to the pedestal 15. The compressor main body 11 compresses air as a gas. The air tank 12 stores the compressed air discharged from the compressor main body 11. A pressure switch 13 and a relief valve 14 are attached to the air tank 12. The pressure switch 13 controls the operation and stop of the compressor 100 based on the pressure in the air tank 12. When the pressure in the air tank 12 exceeds a predetermined pressure, the relief valve 14 releases the compressed air in the air tank 12 to the outside of the air tank 12, thereby reducing the pressure in the air tank 12.

[0014] In this embodiment, the direction from the compressor body 11 toward the air tank 12 is defined as the rear. That is, the air tank 12 is disposed rearward of the compressor body 11. The cooling chamber 17 is disposed rearward of the compressor body 11 and the air tank 12. Note that the cooling chamber 17 may be disposed between the compressor body 11 and the air tank 12 instead of being disposed rearward of the air tank 12. The cooling chamber 17 cools the compressed air discharged from the compressor body 11 before it moves to the air tank 12.

[0015] An electric fan 18 and an aftercooler 19 are attached to the cooling chamber 17. The compressor body 11 is connected to the aftercooler 19 via a flow path 31A, and the aftercooler 19 is connected to the air tank 12 via a flow path 31B. The flow paths 31A and 31B are flow paths for sending compressed air, and for convenience of explanation, the direction of compressed air flow is indicated by arrows. The electric fan 18 sends air inside the housing 1 toward the aftercooler 19. The aftercooler 19 cools the compressed air discharged from the compressor body 11 by heat exchange with the air sent by the electric fan 18. An exhaust port 2A located below the cooling chamber 17 is formed at the rear of the base 2.

[0016] The discharge passage 33A is a passage for discharging the water called drain water as a liquid in the air tank 12. For the sake of convenience of explanation, the direction in which the water flows is indicated by an arrow. A solenoid valve 34 is provided in the discharge passage 33A. The solenoid valve 34 is normally closed and is configured to open, for example, when the compressor 100 is not in use and stopped.

[0017] The diffusion nozzles 21A and 21B are provided at the downstream end of the discharge passage 33A, and diffuse the water sent from the discharge passage 33A in a shower-like manner from a plurality of holes and discharge it into the liquid storage chamber 10. As shown in FIGS. 4 and 5, the diffusion nozzles 21A and 21B can diffuse and discharge the water sent from the discharge passage 33A in a fan shape in the horizontal direction. Here, the horizontal direction is a concept including not only the strict horizontal direction but also a substantially horizontal direction that can be generally regarded as horizontal. Although two diffusion nozzles 21A and 21B are provided here, the number is not limited to this, and one or three or more may be provided.

[0018] As shown in FIG. 4, the liquid storage chamber 10 is provided below the base 2. In the liquid storage chamber 10, a liquid-absorbing member 20 having liquid-absorbing properties and composed of, for example, a sponge is arranged to receive the water discharged from the diffusion nozzles 21A and 21B. The housing 1 has a tray 7 that can be pulled out to the front side (front side), and the liquid storage chamber 10 is formed in the tray 7. The tray 7 has a rectangular box shape with an open upper side. The liquid-absorbing member 20 is arranged in the front in the tray 7.

[0019] FIG. 6 is an enlarged cross-sectional view of part A shown in FIG. 3. As shown in FIGS. 5 and 6, the tray 7 has flanges 7D and 7E formed by extending horizontally from the upper end edges of the left and right side surfaces of the tray 7, respectively. On the other hand, support plates 2B and 2C extending in the front-rear direction are attached to the lower surface of the base 2. The tray 7 is supported by the base 2 so as to be slidable in the front-rear direction by inserting the flanges 7D and 7E into the gaps formed between the base 2 and the support plates 2B and 2C.

[0020] As shown in FIG. 1, an inspection hole 7C through which the internal state of the liquid storage chamber 10 can be confirmed is provided on the front surface of the tray 7. The inspection hole 7C is a through-hole here, but a transparent member may be attached to the through-hole. As shown in FIGS. 4 and 5, protrusions 7F and 7G for positioning the liquid absorbing member 20 are provided on the bottom surface of the tray 7 within the liquid storage chamber 10. The liquid absorbing member 20 is arranged to be disposed between the front surface of the tray 7 and the protrusions 7F and 7G. The protrusions 7F and 7G are provided in two on the left and right here, but are not limited thereto, and one or three or more may be provided. Further, positioning protrusions may be further provided in front of the liquid absorbing member 20.

[0021] Also, as shown in FIGS. 4 to 6, discharge ports 7A and 7B for discharging the air flowing in the housing 1 to the outside of the housing 1 are provided on the side surface of the tray 7. The discharge ports 7A and 7B are formed to be located laterally of the liquid absorbing member 20 on the side surface of the tray 7.

[0022] Next, the operation of the compressor 100 configured as described above will be described. As shown in FIG. 3, the outside air sucked into the housing 1 from the intake port 8A in the direction indicated by the arrow 30 is sucked into the intake port 11A of the compressor main body 11. As shown in FIG. 4, the air compressed by the compressor main body 11 is discharged from the discharge port 11B of the compressor main body 11. The compressed air, which has become high temperature due to compression, is supplied to the aftercooler 19 through the flow path 31A. The electric fan 18 blows the air in the housing 1 toward the aftercooler 19 in the direction indicated by the arrow 32A to cool the aftercooler 19. The compressed air cooled by the aftercooler 19 is supplied to the air tank 12 through the flow path 31B and stored in the air tank 12. The air whose temperature has risen after cooling the aftercooler 19 is sent in the direction indicated by the arrow 32B and exhausted from the exhaust port 2A provided in the base 2 into the liquid storage chamber 10 formed in the tray 7 in the direction indicated by the arrow 32C. Thereby, the surface of the liquid absorbing member 20 is dried. Thereafter, the air is discharged from the discharge ports 7A and 7B provided on the side surface of the tray 7 to the outside of the housing 1 in the direction indicated by the arrow 32D as shown in FIG. 5.

[0023] Water called drain water, that is, water generated when the compressed air is cooled and the water vapor in the air cools, accumulates in the air tank 12 of the compressor 100. As shown in Figure 4, when the solenoid valve 34 is opened, the water accumulated in the air tank 12 is sent to the diffusion nozzles 21A and 21B via the discharge flow path 33A and is discharged in the direction indicated by the arrow 33B.

[0024] As described above, in the compressor 100 according to this embodiment, the compressor body 11, the air tank 12, the discharge flow path 33A, the diffusion nozzles 21A and 21B, and the liquid storage chamber 10 are provided within the housing 1. The air tank 12 stores compressed air discharged from the compressor body 11. The discharge flow path 33A is a flow path for discharging water from the air tank 12. The diffusion nozzles 21A and 21B are provided at the downstream end of the discharge flow path 33A and diffuse and discharge the water sent from the discharge flow path 33A in a shower-like manner. A liquid-absorbing member 20 is provided in the liquid storage chamber 10 to receive the water discharged from the diffusion nozzles 21A and 21B.

[0025] In this embodiment, the water in the air tank 12 is diffused and discharged in a shower-like manner from the diffusion nozzles 21A, 21B, and the discharged water is received by the liquid-absorbing member 20. In this way, the water discharged in a shower-like manner is absorbed by the liquid-absorbing member 20, and the water absorbed by the liquid-absorbing member 20 is more likely to evaporate naturally. Therefore, the frequency of disposing of the water absorbed by the liquid-absorbing member 20 can be reduced. Therefore, according to this embodiment, it is possible to provide the compressor 100 that makes it easy to discharge the water accumulated in the air tank 12.

[0026] In addition, in this embodiment, the diffusion nozzles 21A and 21B diffuse and discharge the water sent from the discharge channel 33A in a fan-shaped shower pattern in the horizontal direction. With this configuration, the water sent from the discharge channel 33A is discharged onto a large area of the upper surface of the liquid absorption member 20, and the evaporation efficiency of the water can be increased. Further, since the water is discharged in the horizontal direction, the dimensional requirements in the height direction for diffusing the water can be suppressed. As a result, the compressor 100 can be miniaturized by reducing the height dimension.

[0027] In addition, in this embodiment, the cooling chamber 17 is disposed behind the compressor main body 11 or the air tank 12, and the air flowing in the housing 1 passes from the periphery of the compressor main body 11 through the cooling chamber 17 and is sent toward the liquid absorption member 20. With this configuration, by applying the hot air after cooling the high-temperature compressed air to the liquid absorption member 20, the evaporation efficiency of the water from the liquid absorption member 20 can be further increased.

[0028] In addition, in this embodiment, the housing 1 has a pull-out tray 7, and a liquid storage chamber 10 is formed in the tray 7. With this configuration, when discarding the water accumulated in the liquid absorption member 20 and the liquid storage chamber 10 or performing maintenance such as replacing the liquid absorption member 20, the tray 7 can be pulled forward for operation, improving workability.

[0029] In addition, in this embodiment, the tray 7 is provided with an inspection hole 7C through which the internal state of the liquid storage chamber 10 can be confirmed. With this configuration, it is possible to check through the inspection hole 7C whether water is accumulated in the liquid absorption member 20, whether the liquid absorption member 20 is dirty, etc., and it is possible to confirm whether maintenance of the liquid absorption member 20 is necessary. Further, when the inspection hole 7C is composed only of a through hole, it becomes possible to easily pull out the tray 7 by inserting a finger into the inspection hole 7C.

[0030] In addition, in the present embodiment, on the side surface of the tray 7, discharge ports 7A and 7B for discharging the air flowing inside the housing 1 to the outside of the housing 1 are provided. With this configuration, since the water vapor evaporated from the water absorbed by the liquid absorption member 20 is promoted to be discharged to the outside of the housing 1, the evaporation efficiency of the water from the liquid absorption member 20 can be further improved.

[0031] The present invention is not limited to the above-described embodiments, and various modifications are included without departing from the technical idea or the main features thereof. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Also, it is possible to add, delete, or substitute some of the configurations of the above-described embodiments with other configurations.

[0032] For example, as shown in FIG. 7, the bottom surface 7H of the tray 7 can also be inclined so as to become lower toward the front. With this configuration, the moisture in the tray 7 moves toward the front. Therefore, the liquid absorption member 20 disposed in the front in the tray 7 can surely absorb the moisture in the tray 7.

[0033] Also, the liquid absorption member 20 is composed of a sponge in the above-described embodiment, but is not limited thereto, and may be composed of other materials having liquid absorption properties. Also, the compressor main body 11 compresses air in the above-described embodiment, but is not limited thereto, and may compress other gases other than air.
