Description

Technical Field

[0001] The utility model relates to the technical field of cooling, dehydrating and drying of air compressors, in particular to a porous cooling, dehydrating and drying mechanism of a laser-specific air compressor. Background Art

[0002] The air compressor for laser, also known as laser-specific air compressor, is an air compressor specially designed for laser equipment. Its main function is to provide high-quality, low-humidity air source for laser equipment such as laser cutting machines, laser marking machines, and laser welding machines to ensure the normal operation and service life of these equipment. When the air compressor compresses the air, mechanical energy is converted into thermal energy, so this process generates heat. At the same time, when the air is compressed, the moisture in the air enters the air compressor, which will affect the life of the air compressor. Therefore, a mechanism integrating cooling, dehydration and drying is needed.

[0003] Chinese patent CN108980013B discloses an air compressor cooling and water removal device, which relates to the technical field of air compressors, including a main body and an air tank. A compression box, a drying mechanism and a heat dissipation mechanism are arranged in the main body. The drying mechanism includes a dehumidification unit, an air inlet pipe and a dust removal unit. The dehumidification unit includes a distribution box, a ventilation plate, a drying box, a motor and a plurality of blades. The dust removal unit includes a lifting assembly and a scraper. The heat dissipation mechanism includes a heat absorption sleeve, a heat absorption pipe, a cooling pipe, a blower, an air outlet pipe, a water pump, two connecting pipes and a plurality of heat dissipation plates.

[0004] In the above structure, the dehumidification unit is working, and humid air enters the distribution box through the air inlet pipe. The air is dispersed by the ventilation plate and divided into multiple airflows to enter the drying box. The motor drives the blades to rotate, so that the activated alumina in the drying box is in full contact with the air to achieve air drying. However, after the activated alumina in the drying box absorbs moisture, the water absorption effect will gradually decrease. Therefore, the internal activated alumina needs to be replaced frequently, which in turn affects the operation of the compressor. Utility Model Content

[0026] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figure 1 — Figure 6 As shown, the utility model provides: a porous cooling, dehydrating and drying mechanism for a laser-specific air compressor, comprising a gas storage tank 1, a drying component 5, a cooling component 6 and an air compressor body 7, a protective shell 2 for protecting the air compressor body 7 is fixed on the top of the gas storage tank 1, a drying component 5 is fixed to one side of the outer side of the protective shell 2 by bolts, the drying component 5 comprises a filter element 501 for filtering dust and a water absorbing core 502 for absorbing water, the water absorbing core 502 is inserted into the filter element 501, the filter element 501 is mainly used to filter dust, and the water absorbing core 502 is used to absorb moisture in the gas. The water absorbing core 502 is inserted into the filter element 501, so that the gas can remove moisture through the water absorbing core 502 while filtering dust through the filter element 501.

[0028] The drying component 5 also includes a limiting shell 504, a negative pressure fan 505 and a drying tank 506. The water absorbent core 502 and the filter element 501 are inserted into the drying tank 506. The limiting shell 504 is inserted into the top of the drying tank 506. A heating pipe 503 is embedded in the limiting shell 504. The drying tank 506 cooperates with the negative pressure fan 505. The negative pressure fan 505 is used to generate negative pressure and extract the gas. The heating pipe 503 is coiled around the outside of the water absorbent core 502, and the top of the water absorbent core 502 is inserted into the limiting shell 504.

[0029] Several groups of protrusions with holes are arranged inside the filter element 501, which help to increase the surface area of ​​the filter element 501, thereby improving the dust filtering effect. When the gas passes through the filter element 501, these protrusions with holes can intercept and absorb tiny particles in the gas, ensuring that only clean gas can continue to pass. The water absorbent core 502 is provided with protrusions for absorbing water inside, and these protrusions can also increase the surface area of ​​the water absorbent core 502, so that it can absorb more water. When the gas passes through the water absorbent core 502, the water will be absorbed by these protrusions and fixed in the water absorbent core 502, so as to achieve the drying of the gas. The heating pipe 503 is spirally sleeved on the outside of the water absorbent core 502. The spiral design can ensure that the heating pipe 503 covers the water absorbent core 502 more evenly, so that the water absorbent core 502 is heated more evenly. When the heating pipe 503 is working, it will transfer heat to the water absorbent core 502, so that the water on the upper part of the water absorbent core 502 evaporates quickly.

[0030] An air intake pipe 4 for air intake is fixedly connected to one side of the drying tank 506, the bottom of the drying tank 506 is fixedly connected to the air inlet of the air compressor body 7 through a pipeline, the air outlet of the air compressor body 7 is connected to the air inlet of the air storage tank 1 through a pipeline, and the air outlet of the air storage tank 1 is fixedly connected to a pressure gauge 3 for detecting the outlet pressure through a pipeline.

[0031] The cooling assembly 6 includes a heat sink 603 and a plurality of heat pipes 604 for heat dissipation. A plurality of heat sinks 603 are evenly fixed on the outside of the protective shell 2. The heat pipes 604 are fixed in the heat sink 603 in a "snake" shape, and each heat pipe 604 is connected to each other through a pipe.

[0032] The cooling assembly 6 also includes a heat dissipation fan 605 for dissipating heat. Several groups of heat dissipation fans 605 are fixedly installed outside the heat sink 603 .

[0033] The cooling component 6 also includes a heat conductor tank 601 and a pump body 602, which are interconnected by a pipeline, and a heat conductor is arranged in the heat conductor tank 601. One end of the heat conductor tank 601 is interconnected with one end of the heating pipe 503 through a pipeline, and one end of the pump body 602 is interconnected with one end of the heat dissipation pipe 604 through a pipeline.

[0034] The cooling assembly 6 also includes several groups of heat conducting sheets 606 and heat conducting pipes 607. The heat conducting sheets 606 are used to absorb the heat in the protective shell 2, and the heat conducting sheets 606 are evenly fixed to the inner wall of the protective shell 2. The heat conducting pipes 607 are fixed in the heat conducting sheets 606 in a "snake" shape. The two heat conducting pipes 607 are interconnected by pipes. One end of the heat conducting pipe 607 is interconnected with the heat dissipation pipe 604 through the pipe, and the other end of the heat conducting pipe 607 is interconnected with the heating pipe 503.

[0035] In this embodiment, the heat conducting sheet 606 and the heat conducting pipe 607 absorb heat, and the heat conducting agent in the heat conducting agent tank 601 circulates in the heating pipe 503, the heat conducting pipe 607 and the heat dissipation pipe 604 through the action of the pump body 602. When the heat conducting agent flows into the heating pipe 503, the heating pipe 503 is heated. When the heat conducting agent flows into the heat dissipation pipe 604, the heat is transferred to the heat dissipation sheet 603, and then the heat is dissipated through the action of the heat dissipation fan 605, so that the air compressor is cooled quickly to avoid damage due to excessive temperature of the air compressor.

[0036] Working principle: When in use, the drying tank 506 is connected to the air inlet of the air compressor, and a filter element 501 is placed in the drying tank 506, and a water absorption core 502 is arranged in the filter element 501. When the air compressor compresses the air and inhales, the air enters the drying tank 506, and the air can filter the dust through the filter element 501, and the moisture in the air will be absorbed by the water absorption core 502, and the water absorption core 502 also has the function of filtering dust. When the air compressor compresses the gas, a large amount of heat is released. A heat conducting sheet 606 and a heat conducting pipe 607 are arranged in the protective shell 2. The heat conducting sheet 606 and the heat conducting pipe 607 absorb the heat, and the heat conducting agent in the heat conducting agent tank 601 is heated in the heating pipe 503 and the heat conducting pipe 607 through the action of the pump body 602. 7 and the heat pipe 604 circulate. When the heat conductive agent flows into the heating pipe 503, the temperature of the heating pipe 503 is relatively high, so that the temperature of the water on the upper part of the water absorbent core 502 rises and evaporates. The heating pipe 503 is spirally wound to increase the contact area with the water absorbent core 502, and the temperature rises faster. After the water on the upper part of the water absorbent core 502 evaporates, the water in the water absorbent core 502 will continue to infiltrate the upper part of the water absorbent core 502. At the same time, the negative pressure fan 505 is started to discharge the evaporated water. When the heat conductive agent flows into the heat pipe 604, the heat will be transferred to the heat sink 603, and then the heat will be dissipated through the action of the heat dissipation fan 605, so that the air compressor is cooled quickly to avoid damage due to excessive temperature of the air compressor.

[0037] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
