Description

Technical Field

[0001] The present application relates to the technical field of cooling equipment, and in particular to a novel cooling filter device. Background Art

[0002] Compressed air is increasingly used in rail vehicles for applications such as brakes, pneumatic doors, air springs, and pneumatic equipment. The quality of compressed air directly impacts the performance of pneumatic equipment. Oil, water, and dust are common in compressed air. Oil deposits can clog pipelines and slow valve operation; mechanical impurities such as dust accelerate wear in pneumatic equipment and affect valve closure. Water poses a particularly serious threat. Condensate in compressed air is acidic, which can cause severe corrosion of valves and pipes. In winter, freezing of condensate can cause brake system failures such as pipe blockage, valve seizure, and malfunction, seriously threatening the safe operation of rail vehicles.

[0003] In order to solve the problem of harmful substances such as oil, water and dust in the compressed air in the prior art, cooling filtering devices have begun to appear in the prior art to remove these harmful substances. However, the equipment in the prior art often only performs filtering work, and the separated oil and water may be drawn back into the gas due to the flowing gas, resulting in poor diversion and separation effects. In addition, after the harmful substances are separated, a sewage discharge structure is required to discharge them. In winter or extreme weather, water vapor condensation may often occur, affecting the normal use of the entire equipment.

[0004] Therefore, the existing technology needs to be further improved and enhanced. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0033] In this application, unless otherwise expressly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0034] like Figures 1 to 4 As shown, the present application provides a new cooling and filtering device, which includes a cooler 10 and an oil-water separator 20. The cooler 10 includes a cooler 10 body and a mounting bracket 1411 arranged on the back of the cooler 10 body. The oil-water separator 20 is arranged at the air outlet 12 of the cooler 10 body, including a separator shell 21, a valve core 22 rotatably arranged inside the separator shell 21, and a sewage discharge component 23 arranged at the end of the separator shell 21. A heating element 233 is arranged in the sewage discharge component 23, and a cyclone cover 24 and an air guide cover 25 are arranged at the end of the valve core 22 near the inlet. The cyclone cover 24 and the air guide cover 25 are arranged sequentially along the air intake direction, and a wind shield 26 is arranged at the end of the valve core 22.

[0035] Among them, Figure 1 and Figure 2 As shown, it can be seen that the mounting bracket 1411 is detachably connected to the cooler 10 body, and the length of the mounting bracket 1411 itself is slightly longer to facilitate installation and improve the load-bearing capacity. In addition, it can be seen from the figure that an electrical control box 15 is arranged between the mounting brackets 1411, and a protective net 13 is arranged on the front of the cooler 10 body.

[0036] It can be understood that the setting of the electrical control box 15 can be connected with most of the electrical control structures within this application to improve the automatic control capability, and the protection net 13 structure is set at the front of the cooler 10 body, which can largely avoid damage to the cooler 10 caused by external impact and improve safety.

[0037] Furthermore, a sewage discharge component 23 is provided to discharge harmful impurities such as oil, water, and dust separated during the cooling and filtering process. A built-in heating element 233 is provided in the sewage discharge component 23 to avoid condensation and freezing of water vapor to a large extent in extreme weather and low temperature conditions, thereby ensuring the normal operation and use of the equipment. Furthermore, the present application centrifugally separates the gas by providing a cyclone hood 24 and guides the gas through an air guide hood 25, which not only improves the oil-water separation effect in the gas, but also guides most of the impurities such as water, oil, and dust to the side wall under the action of centrifugation and guidance, so as to facilitate the flow of these impurities along the side wall to the sewage discharge component 23, thereby reducing the phenomenon of impurities being mixed again due to gas flow, and improving the separation and filtration effect. Furthermore, the filter element can filter the gas passing through the filter element during the flow, thereby further ensuring the filtration effect.

[0038] Further, if Figure 3 and Figure 4 As shown, the diameter of the cyclone cover 24 is larger than the diameter of the wind guide cover 25 , and blade teeth 241 are evenly distributed on the outer edge of the cyclone cover 24 .

[0039] Depend on Figure 3 It can be seen that the cyclone cover 24 and the wind guide cover 25 present a structure similar to a stacking arrangement. The combined design of the two can enhance the directionality of the airflow, guide the airflow to effectively rotate and separate inside the oil-water separator 20, and help improve the efficiency of oil-water separation.

[0040] In addition, the rotating motion of the cyclone cover 24 generates centrifugal force to separate the oil droplets and water from the air flow. The serrated structure helps to increase the rotation speed and centrifugal force of the air flow, and can also increase the surface area of ​​the cyclone cover 24, which may help to increase the contact chance between the oil droplets and the cyclone cover 24, thereby enhancing the separation effect.

[0041] As a preferred embodiment of the present application, Figure 3 As shown, the diameter of the windshield 26 is larger than the diameter of the valve core 22. The windshield 26 is tilted outward from the center of the valve core 22, so that the windshield 26 forms an umbrella-like structure, which can protect the filter element and prevent large particles or foreign matter in the airflow from being pushed upward after being guided and directly impacting the filter element, thereby extending the service life of the filter element. In addition, this inclined guiding structure can further improve the guiding effect of the gas. When the gas passes through the cyclone cover 24 and the wind guide cover 25, it is separated and reaches the windshield 26 through the valve core 22 and is guided again, so that the gas is guided toward the side wall. While improving the separation effect, it can also reduce the gas from flowing directly to the bottom, and the harmful substances accumulated at the bottom are brought out to the valve core 22 through the gas flow, thereby protecting the valve core 22.

[0042] Furthermore, the sewage discharge assembly 23 includes a connecting pipe 231 connected to the separator housing 21 , an emergency plug door 232 connected to the connecting pipe 231 , a heating element 233 arranged therebetween, and a sewage discharge solenoid valve 234 arranged on one side of the connecting pipe 231 .

[0043] It can be understood that the present application provides a sewage discharge component 23 including a connecting pipe 231, an emergency valve 232, a heating element 233 and a sewage discharge solenoid valve 234, so that the entire sewage discharge component 23 can improve the degree of automation under the action of the sewage discharge solenoid valve 234. The setting of the emergency valve 232 can ensure the sewage discharge effect and provide a certain degree of manual operation capability; in addition, by providing the heating element 233, it helps to keep the equipment unobstructed in a low temperature environment, and at the same time, the heating element 233 prevents the oil-water mixture from freezing in the sewage discharge component 23; furthermore, the setting of the temperature control switch 235 can automatically adjust the system temperature when necessary, further improving safety and reliability, and the entire sewage discharge component 23 is set at the bottom, which can be easily disassembled and maintained, and the operation is more convenient.

[0044] And, as Figure 3 As shown, the entire connecting pipe 231 structure is arranged along the vertical direction of the separator body, and the sewage discharge solenoid valve 234 is arranged on one side for electromagnetic control, which can ensure the smooth discharge of pollutants, and by setting the emergency plug door 232, manual sewage discharge operation can be realized under certain circumstances, thereby improving the convenience of use; furthermore, by setting the heating element 233 in the middle section of the connecting pipe 231 and being able to surround most of the structures of the connecting pipe 231, it is ensured that the sewage discharge temperature is increased in a low temperature environment, reducing freezing or condensation, and further improving the reliability of use.

[0045] For the heating element 233, it can adopt the structure of an electric heating plate. On the one hand, it has low cost and is easy to disassemble and assemble. On the other hand, the electric heating plate can be synchronously controlled by a temperature control switch 235 provided at the separator shell 21 near the air outlet 12 of the cooler body 10. A temperature sensor can be provided at the temperature control switch 235 to sense the temperature of the intake air. If the temperature is too low, it can be actively heated during sewage discharge, thereby improving the convenience of operation.

[0046] In a preferred embodiment, Figure 3 As shown, the separator housing 21 includes a valve body 211 and a pipe seat 212 connected to the valve body 211 . The pipe seat 212 is connected to the air outlet 12 of the separator housing 21 . A stepped structure is provided at the connection between the valve body 211 and the pipe seat 212 .

[0047] Among them, the connection between the valve body 211 and the tube seat 212 presents a structure similar to the assembly of a lid and a bottle, which improves the connection strength and sealing performance of the device, ensures the stable operation of the system under various working conditions, and facilitates the disassembly and replacement of the internal structure after a period of use, which is convenient for cleaning and maintenance. The sealing effect is improved by setting the sealing ring 213 structure, further improving the reliability during use.

[0048] For the stepped structure, a common stepped connection structure can be adopted, one of which is provided with a stepped mounting portion, and the other is provided with a stepped mating portion for snap-on assembly, and an assembly groove can be provided at the stepped mounting portion and the mating portion to set a sealing ring 213 in the assembly groove. The sealing ring 213 can adopt an O-ring 213 to further improve the strength of the connection and the sealing effect.

[0049] As a preferred embodiment of the present application, Figure 1 and Figure 2 As shown, sewage discharge components 23 are provided at both ends of the bottom of the cooler body 10. The structure thereof may be similar to the sewage discharge component 23 provided at the oil-water separator 20. It can preliminarily discharge the condensed water and some pollutants in the cooler 10 to further improve the sewage discharge effect and ensure the subsequent cooling filtration effect.

[0050] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0051] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0052] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
