Description

Technical Field

[0001] The utility model belongs to the technical field of diesel filters, and particularly relates to a diesel filtering device. Background Art

[0002] The existing diesel filter used to reduce the oil circuit is composed of a shell, a filter element, a drain plug, a filter seat, a manual pump or an electric pump. The impurities and water in the diesel sink to the water collecting cup at the bottom of the shell and are regularly discharged by manually operating the drain plug. Due to factors such as filtration efficiency, dust capacity, and filter element life of different diesel filters, it is necessary to drain water through the drain plug. If the driver does not drain the water in the filter in time, it is extremely easy to reduce the filtration efficiency of the filter and the service life of the filter element. A water level sensor is required in the filter to remind the staff to drain the accumulated water in the heating device in time.

[0003] During installation, the probe in the water level sensor will penetrate into the accumulated water. Over time, the accumulated water may enter the interior of the water level sensor housing along the probe, thereby corroding the control circuit board inside the housing and causing damage to the control circuit board. Summary of the Utility Model

[0004] The utility model provides a diesel filtering device, aiming to solve the problem that in the prior art, the accumulated water may enter the interior of the water level sensor housing along the probe, thereby corroding the control circuit board inside the housing and causing damage to the control circuit board.

[0005] The utility model is realized as follows: A diesel filtering device includes a housing, a bottom plate, a wire, and a plug. The upper surface of the bottom plate is fixedly connected with an external thread sleeve, and the lower surface of the housing is provided with an internal thread hole matching the external thread sleeve. The lower surface of the bottom plate is communicated with an automatic drain pipe, and an electronic valve is fixedly connected to the inner wall of the automatic drain pipe. The upper surface of the bottom plate is fixedly connected with a device pipe, and through holes are provided on the outer wall of the device pipe. A floating ball is placed inside the device pipe, and an adsorption plate is fixedly connected to the lower surface of the floating ball. An installation plate is arranged on the lower surface of the bottom plate, and a weight sensor and a controller are respectively fixedly connected to the upper surface of the installation plate. A magnet matching the adsorption plate is fixedly connected to the upper surface of the weight sensor. The weight sensor and the electronic valve are electrically connected to the controller, and the controller, the weight sensor, the electronic valve, and the plug are electrically connected to the wire.

[0006] Preferably, a sealing ring is fixedly connected to the upper surface of the bottom plate.

[0007] Preferably, anti-slip lines are arranged on the outer wall of the bottom plate.

[0008] Preferably, a manual drain pipe is connected to the outer wall of the automatic drain pipe, and a manual valve is provided on the outer wall of the manual drain pipe. The manual valve is located below the electronic valve.

[0009] Preferably, the adsorption plate is made of martensitic stainless steel.

[0010] Preferably, the mounting plate and the bottom plate are connected by bolts.

[0011] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects:

[0012] The floating ball changes with the height of the accumulated water in the outer shell, so that the distance between the adsorption plate and the magnet above it changes. The change in the distance between the adsorption plate and the magnet above it causes a change in the adsorption force between the adsorption plate and the magnet. The adsorption force between the adsorption plate and the magnet is detected by a weight sensor. When the adsorption force between the adsorption plate and the magnet is lower than the set range, it means that the adsorption plate is far from the magnet. The weight sensor sends a signal to the controller. The controller receives the signal from the weight sensor and controls the electronic valve to open, so that the automatic drain pipe drains the accumulated water in the outer shell. The floating ball and the adsorption plate will drop with the water level. When the adsorption force between the adsorption plate and the magnet is higher than the set range, it means that the adsorption plate is close to the magnet. The weight sensor sends a signal to the controller. The controller receives the signal from the weight sensor and controls the electronic valve to close, thus realizing automatic drainage. There is no need to use a water level sensor, avoiding the possibility that the accumulated water may enter the housing of the water level sensor along the probe and corrode the internal control circuit board.

The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] An embodiment of the utility model provides a diesel fuel filtering device, as Figures 1-4 shown, which includes a housing 1, a bottom plate 2, a wire 3 and a plug 4. An externally threaded sleeve 5 is fixedly connected to the upper surface of the bottom plate 2, and an internally threaded hole matching the externally threaded sleeve 5 is provided on the lower surface of the housing 1. An automatic drain pipe 8 is communicated with the lower surface of the bottom plate 2, and an electronic valve 9 is fixedly connected to the inner wall of the automatic drain pipe 8. A device pipe 10 is fixedly connected to the upper surface of the bottom plate 2, and a through hole 11 is provided on the outer wall of the device pipe 10. A floating ball 12 is placed inside the device pipe 10, and an adsorption plate 13 is fixedly connected to the lower surface of the floating ball 12. An installation plate 14 is provided on the lower surface of the bottom plate 2, and a weight sensor 15 and a controller 17 are respectively fixedly connected to the upper surface of the installation plate 14. A magnet 16 matching the adsorption plate 13 is fixedly connected to the upper surface of the weight sensor 15.

[0021] It should be noted that in the prior art, water accumulation may enter the interior of the housing of the water level sensor along the probe, thereby corroding the control circuit board inside the housing and causing damage to the control circuit board. Therefore, in order to solve the problem that in the prior art, water accumulation may enter the interior of the housing of the water level sensor along the probe, thereby corroding the control circuit board inside the housing and causing damage to the control circuit board, in this solution, the floating ball 12 changes with the height of the water accumulation in the housing 1, so that the distance between the adsorption plate 13 and the magnet 16 above the magnet 16 changes. The change in the distance between the adsorption plate 13 and the magnet 16 above the magnet 16 causes a change in the adsorption force between the adsorption plate 13 and the magnet 16. The adsorption force between the adsorption plate 13 and the magnet 16 is detected by the weight sensor 15. When the adsorption force between the adsorption plate 13 and the magnet 16 is lower than the set range, it indicates that the adsorption plate 13 is far from the magnet 16. The weight sensor 15 sends a signal to the controller 17. The controller 17 receives the signal from the weight sensor 15, and the controller 17 controls the electronic valve 9 to open, so that the automatic drain pipe 8 drains the water accumulation in the housing 1. The floating ball 12 and the adsorption plate 13 will drop with the water level. When the adsorption force between the adsorption plate 13 and the magnet 16 is higher than the set range, it indicates that the adsorption plate 13 is close to the magnet 16. The weight sensor 15 sends a signal to the controller 17. The controller 17 receives the signal from the weight sensor 15, and the controller 17 controls the electronic valve 9 to close, thereby realizing automatic drainage without using a water level sensor, avoiding the possibility that water accumulation may enter the interior of the housing of the water level sensor along the probe and corrode the internal control circuit board.
