Description

Technical Field

[0001] The utility model belongs to the technical field of sewage filtering equipment, in particular to a sewage tank with an increased filtering function. Background Art

[0002] High-pressure compressors are commonly used in industrial production. During operation, they generate large amounts of oil-gas mixtures, which need to be treated through a sewage system to prevent environmental pollution. Traditional sewage systems typically use sewage tanks to separate the oil and gas. However, these traditional sewage tanks have certain problems in practical applications.

[0003] In a traditional blowdown tank, the oil-gas mixture enters the tank, where it is deflected and diffused by a baffle plate to reduce its velocity. It is then discharged through a silencer filter on the upper baffle. However, due to the high pressure and large exhaust volume of the oil-gas mixture, the oil filtration effect is not ideal, resulting in the exhaust air containing oil and gas. Furthermore, oil condenses on the outer surface of the blowdown tank, further polluting the surrounding environment.

[0004] In order to solve this problem, a sewage tank with increased filtering function is proposed. Utility Model Content

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] The utility model can capture larger oil droplets through the wire filter, and the activated carbon filter absorbs fine oil mist. The double filtering structure significantly improves the processing capacity of the oil-gas mixture.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 2As shown, the utility model provides a sewage tank with an increased filtering function, comprising a tank shell 1 with an opening at the upper end, a baffle separation plate 2 at the sewage inlet end of the tank shell 1, a partition 3 provided inside the tank shell 1, a mounting post 4 with one end extending to the outside of the opening of the tank shell 1 on the partition 3, a silencer filter 5, a steel wire filter 6 and an activated carbon filter 7 provided in sequence along the upper edge of the mounting post 4 toward the opening of the tank shell 1, a cover shell 8 provided at the end of the mounting post 4, and an exhaust channel 9 provided between the cover shell 8 and the tank shell 1.

[0022] Among them, regarding the structural design between the tank shell 1, the steel wire filter 6 and the activated carbon filter 7:

[0023] The steel wire filter 6 can capture larger oil droplets, while the activated carbon filter 7 can absorb fine oil mist. This dual filtration design significantly improves the processing capacity of the oil-gas mixture, ensuring that the oil content in the exhaust gas is greatly reduced. Through effective oil-gas separation and filtration, the amount of oil discharged with the air is reduced, reducing pollution to the external environment, especially reducing the problem of oil condensation in the surrounding environment.

[0024] Moreover, the steel wire filter 6 can be used for a long time and cleans itself by gravity, and the replacement cycle of the activated carbon filter 7 is extended, which reduces maintenance costs and labor intensity. The added filtering structure is simple in design, with low component costs, does not damage the original sewage tank structure, and is easy to produce and maintain.

[0025] On the basis of the above solution, a further preferred solution includes: a stud 10 is provided on the mounting column 4 , a cover 8 is sleeved on the outer side of the stud 10 , and a nut 11 for fixing the cover 8 is provided on the stud 10 .

[0026] The design of the studs 10 and nuts 11 allows the cover 8 to be easily disassembled, facilitating the cleaning, inspection and replacement of the internal filter, thereby improving the convenience of maintenance. The presence of the cover 8 can protect the internal silencer filter and filter from the influence of the external environment, such as preventing the entry of dust, moisture or other impurities. Since the internal components are better protected, their service life may be extended, reducing the replacement frequency and related maintenance costs.

[0027] The length of the stud 10 and the position of the nut 11 can be adjusted to accommodate filters of different sizes and specifications, thereby increasing the adaptability of the device.

[0028] Preferably, the mounting column 4 includes a first distance tube 12 , a second distance tube 13 and a third distance tube 14 for installing the silencer filter 5 , the wire filter 6 and the activated carbon filter 7 respectively, and the first distance tube 12 is arranged on the partition 3 .

[0029] The use of distance tubes ensures that the appropriate distance between each filter is maintained, preventing the filters from being too closely contacted or squeezed, thereby ensuring the flow area and flow rate of the oil-gas mixture when passing through the filter. The distance tubes provide stable support for the installation of the filter, reducing the risk of filter displacement or damage caused by vibration or airflow impact. Since the distance tubes help maintain the correct position and spacing of the filters, they can reduce wear and damage to the filters, thereby extending their service life;

[0030] The fixed distance tube can also be set to different lengths to accommodate filter screens of different thicknesses and specifications, making the design more flexible and adaptable to different application requirements;

[0031] The setting of the distance pipe makes the installation of the silencer filter and the filter screen more convenient and quick, and when replacement or cleaning is needed, each filter screen can be operated separately, which simplifies the maintenance process.

[0032] Preferably, a steel plate mesh 15 for supporting the activated carbon filter 7 is provided on the third distance tube 14 , and a gasket 18 is provided between the steel plate mesh 15 and the third distance tube 14 .

[0033] Since the steel plate mesh 15 provides uniform support, the physical damage of the activated carbon filter 7 during operation is reduced, thereby extending its service life. By adjusting the thickness of the gasket 18, it can adapt to activated carbon filters of different thicknesses and specifications, increasing the adaptability of the equipment.

[0034] Enhanced support stability: The use of the steel plate mesh 15 provides a solid support for the activated carbon filter 7, preventing the filter from shifting under airflow impact or vibration, and increasing the stability of the entire filter structure.

[0035] Preferably, a cylindrical shell 16 is provided inside the opening of the tank shell 1 , and the steel wire filter 6 and the activated carbon filter 7 are located inside the cylindrical shell 16 and elastically fit with the inner wall of the cylindrical shell 16 .

[0036] A sealing strip 17 is provided at the connection between the tank shell 1 and the cylinder shell 16 .

[0037] Specifically, the inner diameter of the cylindrical shell 16 is 1 mm smaller than the outer diameter of the wire filter 6 and the activated carbon filter 7. The filter relies on tension to form a sealing surface with the inner wall of the component 5 to prevent gas from escaping. The design of the cylindrical shell 16 makes the installation and replacement of the filter more convenient, simplifies the maintenance procedure, and the use of the sealing strip 17 can effectively prevent the oil-gas mixture from leaking at the connection between the tank shell 1 and the cylindrical shell 16, thereby improving the sealing performance of the entire sewage tank.

[0038] The working principle and use process of this utility model:

[0039] After entering the tank shell 1, the oil-gas mixture is deflected and diffused by the deflection separation plate 2 to reduce its flow rate, and then discharged through the silencer filter 5 on the partition 3. The mixed airflow after preliminary filtration is then passed through the wire filter 6 to capture larger oil droplets and the activated carbon filter 7 to filter out oil mist in the air before being discharged from the exhaust channel. Since the sewage discharge is intermittent, the oil accumulated on the wire filter 6 will fall into the sewage tank due to gravity. After separation, the sewage is deposited at the bottom of the tank body and can be cleaned regularly through the manual drain valve later, completing the entire sewage discharge operation.

[0040] When parts need to be replaced, the nut 11 is removed, the cover 8 is taken off, and the filter screen is removed and replaced in the cylindrical shell 16 .
