Description

Technical Field

[0001] This invention relates to the field of fire-resistant oil regeneration technology, specifically to a fire-resistant oil regeneration device regeneration filter element alignment monitoring system. Background Technology

[0002] In existing fire-resistant oil regeneration treatment devices, the regeneration filter element is filled with adsorbent packing. Fire-resistant oil is pumped from the outside of the regeneration filter element through the packing into the interior of the regeneration filter element, and then discharged from the oil outlet connected to the mounting housing.

[0003] To ensure the effectiveness of oil regeneration, the amount of packing material must be adapted to the amount of oil being processed on site. Therefore, the volume and weight of the regeneration filter element are much higher than other types of filter elements, which means that its installation method can only be vertical insertion. The entire regeneration filter element is connected to the insertion port of the mounting housing through its bottom mounting port, and the connection is sealed by a single O-ring installed at the bottom of the regeneration filter element.

[0004] Because of the vertical insertion installation, the housing is always filled with oil after the first use. This makes it impossible to visually inspect the bottom of the housing for foreign objects that may affect the proper installation of the filter element when it is replaced. As a result, during the installation, use, and relocation of the fire-resistant oil regeneration device, the regeneration filter element may not be properly installed inside the housing or may shake, leading to a short circuit and bypass of the oil circuit at the bottom O-ring.

[0005] The fire-resistant oil regeneration treatment device is a sealed stainless steel tank. Oil is pumped through the regeneration filter element under external pressure, filling the entire housing with fire-resistant oil and maintaining a positive pressure state. To monitor whether the regeneration filter element within the sealed housing is correctly installed and in use, signals must be transmitted through the stainless steel housing without compromising its airtightness, and the materials in contact with the fire-resistant oil must be compatible with it.

[0006] Currently, some users measure the installation port of the regenerated filter element or the insertion port of the housing and compare it with other filter elements, then install other filter elements in the housing of the regenerated filter element to replace it. In order to prevent the damage caused by incorrect use to the fuel system and regeneration treatment device, the filter element and housing should be designed for proper matching. Summary of the Invention

[0007] To address the problems in the prior art, this invention provides a regeneration filter element alignment monitoring system for a fire-resistant oil regeneration device. This system enables the alignment and position monitoring of the regeneration filter element during blind installation with a full oil load inside the mounting housing without compromising the airtightness and integrity of the mounting housing. Furthermore, it achieves hardware matching between the regeneration filter element and the mounting housing through a simple hardware arrangement, thereby integrating alignment, monitoring, and error prevention to ensure the safe and stable operation of the fire-resistant oil regeneration device.

[0008] This invention is achieved through the following technical solution: A fire-resistant oil regeneration device regeneration filter element alignment monitoring system includes: a housing and a regeneration filter element located inside the housing; a magnetic sensor is disposed on the outside of the housing; a permanent magnet is disposed inside the regeneration filter element; the magnetic sensor cooperates with the permanent magnet; multiple magnetic sensors and permanent magnets are disposed, and each permanent magnet corresponds to a magnetic sensor; the output end of the magnetic sensor is connected to the input end of a controller; the output end of the controller is connected to the input end of an audible and visual alarm. The magnetic sensor is equipped with a normally open reed switch. When the magnetic field of the permanent magnet covers the magnetic sensor, the internal reed of the normally open reed switch is attracted, forming a closed circuit and sending a signal to the controller.

[0009] Preferably, the housing has a filter element insertion port, and the regeneration filter element is matched with the filter element insertion port.

[0010] Preferably, the magnetic sensor uses a stainless steel housing.

[0011] Preferably, the magnetic sensor is detachably mounted on the outside of the housing.

[0012] Preferably, the permanent magnet is sealed inside the regeneration filter element.

[0013] Preferably, the permanent magnet is horizontally positioned inside the regeneration filter element.

[0014] Preferably, the permanent magnet is made of rare earth material.

[0015] Preferably, four magnetic sensors are provided, forming four sets of sensing units with the permanent magnet, and outputting five different sets of corresponding magnetic induction signals; it is set that when the controller receives four sets of corresponding magnetic induction signals at the same time, the regeneration filter element and the housing are successfully aligned.

[0016] Preferably, the magnetic sensors are evenly arranged on the outside of the housing.

[0017] Preferably, the controller's output is also connected to a display screen.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses a regeneration filter element alignment monitoring system for a fire-resistant oil regeneration device. A magnetic sensor and a permanent magnet are set up to form a magnetic induction unit. The controller determines the position of the regeneration filter element based on the combination of signals emitted by the magnetic sensor and the permanent magnet. Whether the regeneration filter element is installed in the housing or moved and used by the fire-resistant oil regeneration device, the controller can only indicate that the alignment and installation are successful or the operating environment is normal when it receives four sets of magnetic induction signals at the same time.

[0019] The fire-resistant oil regeneration device regeneration filter element alignment monitoring system proposed in this invention can pre-position the correct installation position by pre-assembling the regeneration filter element and installation housing during production. During installation, the staff only needs to observe the prompts of the fire-resistant oil regeneration device control system and the audible and visual alarm to determine whether the installation is in place. This solves the problem in the prior art that the staff cannot visually see whether there are contaminants at the bottom of the installation housing when the oil is full, which helps to improve installation efficiency, accuracy and safety.

[0020] During the movement and use of the fire-resistant oil regeneration device, the regeneration filter element installed in the regeneration housing may sometimes shake. If the regeneration filter element is not reset after the fire-resistant oil regeneration device is moved into place, the oil will short-circuit through the single-groove O-ring seal at the connection between the regeneration filter element and the regeneration housing, affecting the performance. This system can monitor the alignment of the filter element during use and promptly remind the operator to handle the situation.

[0021] This invention achieves matching and verification between the regenerable filter element and the housing through a simple hardware arrangement, thereby avoiding human damage caused by operators measuring and installing the regenerable filter element or housing. Attached Figure Description

[0024] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0025] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided to fully and completely disclose the invention and to fully convey its scope to those skilled in the art. The terminology used in the exemplary embodiments illustrated in the drawings is not intended to limit the invention. In the drawings, the same units / elements are referred to by the same reference numerals.

[0026] Unless otherwise stated, the terms used herein (including technical terms) have their common meaning as understood by one of ordinary skill in the art. Furthermore, it is understood that terms defined in commonly used dictionaries should be understood to have a meaning consistent with the context of their relevant field, and not to be interpreted as having an idealized or overly formal meaning.

[0027] The present invention will be further described in detail below with reference to specific embodiments. These descriptions are for explanation purposes only and are not intended to limit the scope of the invention.

[0028] In the existing technology, the regeneration shell 3 and the outer shell of the regeneration filter element 4 of the fire-resistant oil regeneration device 7 are all made of stainless steel. Since the regeneration shell 3 is in a positive pressure sealed state during use, it is not possible to perform drilling operations or other work that affects the sealing and integrity of the shell 3. In other words, wired transmission signals such as electrical signals and electromagnetic signals that are easily shielded cannot be used. After research, it was found that the magnetic permeability of austenitic stainless steel is very low and it is a non-magnetic material. Therefore, a magnetic field is used as the signal transmission medium.

[0029] This invention discloses a regeneration filter element alignment monitoring system for a fire-resistant oil regeneration device, referring to... Figure 1 , 2 3, including: housing 3 and regeneration filter element 4 located inside housing 3. Specifically, housing 3 is provided with filter element insertion port 5. Regeneration filter element 4 cooperates with filter element insertion port 5. Regeneration filter element 4 is connected to housing 3 by vertically inserting into insertion port 5 of housing 3. The connection port is sealed by O-ring sealing ring 6 at the bottom of regeneration filter element 4.

[0030] A magnetic sensor is installed on the outside of the housing 3. The magnetic sensor is made of stainless steel and can be detachably installed on the outside of the housing 3. For example, it can be fixed to the outside of the housing 3 by means of a hose clamp, thereby enabling it to move vertically along the housing 3.

[0031] The magnetic sensor works in conjunction with the permanent magnet 2. The output of the magnetic sensor is connected to the input of the controller 8, and the output of the controller 8 is connected to the input of the audible and visual alarm. The magnetic sensor is equipped with a normally open reed switch. When the magnetic field of the permanent magnet 2 covers the magnetic sensor, the internal reed of the normally open reed switch is attracted, forming a closed circuit and sending a signal to the controller 8.

[0032] The output of controller 8 is also connected to a display screen.

[0033] The regeneration filter element 4 is equipped with a permanent magnet 2. Specifically, the permanent magnet 2 is sealed inside the regeneration filter element 4. The permanent magnet 2 is a cuboid shape and is placed horizontally to ensure that the magnetic poles are aligned and to prevent the magnetic field from spreading in other directions.

[0034] The permanent magnet 2 is made of rare earth material, which makes it compatible with fire-resistant oil and allows it to be immersed in fire-resistant oil for a long time along with the regenerated filter element 4.

[0035] Multiple magnetic sensors and permanent magnets 2 are provided, with each permanent magnet 2 corresponding to one magnetic sensor. The magnetic sensors are evenly arranged on the outside of the housing 3. Specifically, four magnetic sensors are provided, forming four sets of sensing units with the permanent magnets 2, outputting five different sets of corresponding magnetic induction signals. It is set that when the controller 8 receives all four sets of corresponding magnetic induction signals simultaneously, the regeneration filter element 4 and the housing 3 are successfully aligned. In one embodiment, the four magnetic sensors 1 are arranged at 90° intervals within concentric circles (e.g., ...). Figure 1 As shown), a simple hardware arrangement is achieved while preventing mutual interference. Four sets of sensing units are arranged in... Figure 1 The diagram shows a planar arrangement, but during actual production pre-assembly, the vertical positions of different groups of magnetic induction units and permanent magnets 2 can be adjusted. The four groups of induction units can generate five different arrangements, equivalent to forming five different magnetic induction alignment signals. Any one group can be selected during production. When the controller 8 of the fire-resistant oil regeneration device 7 does not simultaneously receive all four alignment signals, the fire-resistant oil regeneration device 7 will generate an alarm, preventing users from replacing the filter element simply because the installation port size of the filter element or housing 3 is consistent.

[0036] Reference Figure 4 In the vertical installation of the regeneration filter element 4, during the regeneration of the fire-resistant oil regeneration device, when the permanent magnet 2 inside the regeneration filter element 4 reaches the designated position, the magnetic field of the permanent magnet 2 covers the magnetic induction unit set outside the shell. The reed inside the normally open reed switch in the magnetic induction unit is attracted, forming a closed circuit. At this time, after the control system of the fire-resistant oil regeneration device 7 collects the signal that the installation is in place, the audible and visual alarm emits green sound and light, and the control system screen generates text prompts for easy observation by the operator.

[0037] Because the installation process is still in a state of blind installation with full oil, there are two situations: one is that after insertion, the magnetic field sensing unit directly senses and aligns with the magnetic field of the permanent magnet 2, and generates a signal output; the other is that after insertion, the magnetic field sensing unit is misaligned with the permanent magnet 2 and cannot sense the magnetic field. In this case, the regeneration filter element 4 needs to be rotated and aligned after insertion until the magnetic field sensing unit senses the magnetic field signal of the permanent magnet 2 and generates a signal output.

[0038] This invention incorporates four sets of magnetic sensors and permanent magnets 2. The controller 8 only issues a successful alignment notification when it receives all four sets of signals simultaneously, thus mitigating the risk of false alarms from single-point sensors. This ensures the unique spatial position and accurate installation of the regenerated filter element 4 under complex operating conditions, thereby improving the operational safety and oil purification quality of the fire-resistant oil system. Furthermore, the four sets of magnetic sensors can generate five arrangement patterns, preventing the mixing and replacement of other filter elements. Specifically, during the movement and use of the fire-resistant oil regeneration device 7, if any one or more signals are missing, it can be determined that the regenerated filter element 4 is incorrectly installed or malfunctioning within the housing 3. The controller 8, through program logic, sends signals to the audible and visual alarm and the display screen, causing the alarm to emit a red light and the display screen to generate a text notification.

[0039] In summary, the regeneration filter element alignment monitoring system of the fire-resistant oil regeneration device of the present invention can transmit magnetic signals through the stainless steel housing 3 without damaging the integrity and airtightness of the housing 3, and monitor the position of the regeneration filter element 4 in real time during the mobile use process, which helps to improve the efficiency of use. It can also realize the integrated installation alignment, use monitoring and anti-misinstallation of the regeneration filter element 4 of the fire-resistant oil regeneration device 7, thereby improving the safety of the fire-resistant oil system and the fire-resistant oil in the regeneration device.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the technical solution of the present invention in any way. Those skilled in the art should understand that, without departing from the spirit and principles of the present invention, the technical solution can be modified and replaced in several simple ways, and these modifications and replacements are all within the scope of protection covered by the claims.
