Description

Technical Field

[0001] The utility model relates to the technical field of diesel filters, in particular to a filter detection device. Background Art

[0002] Diesel filters can be divided into diesel coarse filters, diesel water separators, and diesel fine filters according to their functions. As the name suggests, the main function of the diesel coarse filter is to initially filter out larger impurities in diesel, and it is generally installed in the fuel tank. The main function of the oil-water separator is to separate water from diesel. The presence of water is extremely harmful to the diesel engine fuel supply system, and rust, wear, and jamming may even worsen the diesel combustion process. In addition, the sulfur content of diesel in my country is relatively high, and it is easy to react with water during combustion to produce sulfuric acid, which then corrodes engine parts. Under the National IV standard, the diesel fine filter is mainly used to filter 3-5μm impurities in diesel, and is the main filtering component.

[0003] The diesel filter disclosed in publication number CN205330847U has the characteristics of providing a guide structure inside the outer shell to guide the diesel and impurities entering the outer shell to the inner wall of the outer shell, so that the diesel and impurities fall by gravity and flow to the bottom of the outer shell, thereby preventing the impurities in the fuel from adhering to the filter paper core and causing the filter element assembly to be blocked, reducing the frequency of replacing the filter element assembly and extending the service life of the diesel filter.

[0004] However, the diesel filter has the following disadvantages:

[0005] The inability to adjust the amount of diesel entering the diesel filter, and thus the inability to ensure that the filter processes the right amount of diesel, will cause impurities and pollutants to enter the engine system and cause damage. At the same time, the inability to detect the diesel entering the filter makes it impossible to detect the condition of the filter in a timely manner.

[0006] As the diesel engine vibrates, the filter will also vibrate. Over time, this will cause the filter to loosen, making its connection loose, thereby reducing the filtering efficiency and causing the engine to stall or even fail to start. Utility Model Content

[0007] The technical problem solved by the utility model is to provide a filter detection device which is highly practical, can be operated simply and has a relatively simple structure. It solves the problem proposed in the above-mentioned background technology that the amount of diesel entering the diesel filter cannot be adjusted, and thus the filter cannot be guaranteed to process an appropriate amount of diesel. As the diesel engine vibrates, the filter is also driven to vibrate. Over time, the filter becomes loose. At the same time, the diesel entering the filter cannot be detected, resulting in the inability to timely detect the condition of the filter.

[0008] To achieve the above objectives, the utility model is implemented through the following technical solutions: a filter detection device, including a filter housing, a filter cover fixedly connected to the top of the filter housing, a connecting cover through-connected to the top of the filter cover, a threaded pattern arranged inside the connecting cover, a connecting component threadedly connected to the surface of the threaded pattern, a shaft cover arranged on the top of the connecting component, connecting pipes symmetrically connected to the two sides of the shaft cover about the central axis, and an adjusting component for adjusting the internal flow rate arranged on the surface of the connecting pipe.

[0009] Optionally, the connecting assembly includes a threaded column threadedly connected to the surface of the threaded pattern, and directional holes are axially symmetrically provided on both sides of the bottom end of the threaded column. A spring is fixedly connected to the inner bottom of the directional hole, and a limit button is provided at one end of the spring for limiting and fixing.

[0010] Optionally, limiting holes adapted to the limiting buttons are provided on both sides of the bottom end of the connection cover, and the limiting holes and the directional holes on both sides of the bottom end of the threaded column threadedly connected into the interior of the connection cover are on the same horizontal line.

[0011] Optionally, the adjustment component includes a tee pipe arranged on the surface of the connecting pipe, a threaded rod for adjusting the depth is arranged inside the tee pipe, a handle for driving the threaded rod to rotate forward and reverse is arranged at the top of the threaded rod, and a flow sensor for monitoring the internal flow is arranged on the side of the tee pipe.

[0012] Optionally, a through hole is opened inside the threaded column, and the through hole is in the same vertical line as the connecting cover and the filter cover, and is connected vertically.

[0013] Optionally, a filter paper cartridge for filtering impurities inside diesel fuel is sleeved inside the filter housing, and a filter element is inserted into the filter paper cartridge.

[0014] The utility model provides a filter detection device, which has the following beneficial effects:

[0015] 1. The filter detection device, through the setting of the adjustment component, people can drive the threaded rod to rotate inside the tee by rotating the counter-hand, so as to adjust the depth of the threaded rod inside the tee, that is, to adjust the exposed size of the circular holes on both sides of the tee, and then adjust the flow rate of diesel entering the filter housing, so as to ensure that the filter can handle an appropriate amount of diesel, improve the filtering effect, and prevent impurities and pollutants from entering the engine system. At the same time, an appropriate amount of diesel entering the filter can reduce excessive load and loss, and extend the service life of the filter. At the same time, the flow rate entering the filter housing can be monitored by the flow sensor to determine whether the filter is blocked and damaged, so as to achieve timely detection and maintenance.

[0016] 2. The filter detection device, through the setting of the connecting component, when installing the filter housing, the filter cover on the top of the filter housing can be aligned with the threaded column, and the filter housing can be rotated to install the filter housing on the surface of the threaded column until the directional holes on both sides of the bottom end of the threaded column and the limiting holes on both sides of the bottom end of the external connecting cover are on the same horizontal line, so that the limiting button is acted upon by the elastic force of the spring and is pushed out to the inside of the limiting hole, thereby fixing the filter cover and the connecting cover to the threaded column, preventing the filter housing from loosening and falling off due to vibration, thereby improving the stability of the filter housing installation.
