Description

Technical Field

[0001] This invention relates to the field of fire-resistant oil regeneration, and in particular to a fire-resistant oil regeneration system and a targeted removal and regeneration device for acidic substances. Background Technology

[0002] An oil treatment device is a device used to filter and treat fire-resistant fuel oil. Existing oil treatment devices are difficult to perform online oil treatment. At the same time, during the treatment process, the oil resistance in the device is too high, which can easily damage the oil pump. In addition, they lack alarm functions, and it is difficult to remind in time when the device pressure is too high or the filter element needs to be replaced, which affects the safe operation of the device and the safety of the device is poor. Therefore, a fire-resistant fuel oil regeneration system is proposed.

[0003] Furthermore, in the oil treatment process, a regenerator and a regenerator filter element are usually used together. The adsorbent filled in the regenerator filter element removes impurities from the phosphate ester hydraulic fluid, thereby achieving the purpose of filtering oily liquids such as phosphate ester hydraulic fluid. During use, when the filter element is saturated with impurities, it needs to be replaced. Existing regenerators are generally sealed by a flange structure, and the opening and closing steps of the regenerator housing are cumbersome, causing inconvenience for filter element replacement. Therefore, a fire-resistant oil regeneration system and an acid-targeted removal regenerator are proposed. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this section, the abstract and the title of the invention. Such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0006] Therefore, the technical problem that the existing equipment has poor safety in the oil treatment process is to be solved by the present invention.

[0007] To solve the above technical problems, the present invention provides the following technical solution: a fire-resistant oil regeneration system, comprising a regeneration system, including an inlet valve, an oil suction filter connected to the outside of the inlet valve, an oil pump disposed on the outside of the oil suction filter, a pressure gauge connected to the outside of the oil pump, a pressure alarm connected to the outside of the pressure gauge, a pre-fine filter pressure gauge connected to the outside of the pressure alarm, a dual fine filter connected to the outside of the pre-fine filter pressure gauge, and an outlet valve connected to the outside of the dual fine filters;

[0008] The oil pump is connected in parallel with an overflow valve;

[0009] A regenerator mechanism is provided between the pressure alarm and the pressure gauge before fine filtration. A regeneration bypass valve is connected in parallel to the regenerator mechanism. An oil drain valve is connected to the outside of the regeneration bypass valve.

[0010] The dual fine filters are connected in parallel with a fine filter differential pressure alarm, and a sampling valve is connected between the dual fine filters and the oil outlet valve.

[0011] The beneficial effects of this invention are that the system can perform oil treatment operations online, with a large oil treatment capacity per unit of removed medium and low oil loss. Simultaneously, the overflow valve diverts the flow, protecting the oil pump and the system. The system pressure alarm primarily provides electrical protection against overpressure. When the oil temperature is low, the system pressure is high; if the pressure exceeds the alarm's set value, the alarm will sound and the system will shut down, alerting the operator to take action. The fine filter differential pressure alarm can also alert the operator to replace the fine filter element when the filter element becomes saturated with impurities and the differential pressure reaches 0.35 MPa. This improves the operational safety of oil-using equipment and makes a positive contribution to improving the quality and efficiency of power plant operations.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0041] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0042] Example 1

[0043] Reference Figure 1 This is the first embodiment of the present invention, which provides a fire-resistant oil regeneration system.

[0044] Specifically, the fire-resistant oil regeneration system 100 consists of an oil inlet component, a regeneration component, a filter component, a safety component, and an electrical system.

[0045] Furthermore, the oil inlet components include an oil inlet valve 101, an oil suction filter 102, and an oil pump 103, which are connected to each other, allowing the pressure oil to be treated to enter the regeneration system. The regeneration components include a regenerator mechanism 200, which removes acidic components and polar impurities from the pressure oil entering it during actual use, thereby reducing the acid value. The pressure oil after being treated by the regenerator then enters the filter components composed of dual fine filters 111 for further processing to ensure the cleanliness of the regenerated oil.

[0046] Safety components and electrical systems are used to ensure the efficient and safe operation of the entire system. Safety components include an overflow valve 104 and a pressure alarm 105. The overflow valve 104 is installed in parallel with the oil pump 103 on the oil inlet pipeline, and a pressure gauge 106 is also installed on the oil inlet pipeline. When the pressure gauge 106 shows excessive pressure (i.e., when the resistance of the oil in the system is too great), the overflow valve 104 can divert the flow to protect the oil pump 103 and the system. At the same time, the system pressure alarm 105 provides electrical protection against overpressure in the system. When the oil temperature is low, the system pressure is high. If the pressure exceeds the alarm's set value, the pressure alarm 105 will sound an alarm and stop the machine, reminding the operator to handle the situation. The fine filter differential pressure alarm 107 is used to protect the fine filter element. When the fine filter element is saturated with impurities and the differential pressure reaches 0.35 MPa, the fine filter differential pressure alarm 107 will sound an alarm to prompt the replacement of the fine filter element.

[0047] The electrical system is used to control the start-up and stop of the equipment, and to ensure timely shutdown after the pressure alarm issues an alarm signal.

[0048] Furthermore, during system flushing, open the inlet valve 101, outlet valve 113, regeneration bypass valve 108, and pressure gauge 110 before fine filtration, start the oil pump 103, and circulate the oil in the oil tank. After circulating for a period of time, gradually close the regeneration bypass valve 108 to put the regenerator mechanism 200 into operation and flush it. Test the cleanliness of the outlet oil until the cleanliness of the outlet oil is qualified. After the system is flushed and used, the oil can be completely discharged through the drain valve 109. At the same time, oil samples can also be extracted through the sampling valve 112 during use.

[0049] Example 2

[0050] Reference Figure 2-5 This embodiment provides an acidic substance targeted removal and regeneration device.

[0051] The acid-targeted removal and regenerator includes a regenerator mechanism 200.

[0052] Specifically, the regenerator mechanism 200 includes a hollow housing 201, a cover plate 202 for sealing is detachably mounted on the top of the housing 201, a push rod 206 is integrally provided on the outer wall of the cover plate 202, and a regeneration filter element 207 is installed inside the housing 201.

[0053] Preferably, the regenerated filter element 207 is filled with a material compatible with fire-resistant oil and a high-efficiency adsorbent. The adsorbent in the regenerated filter element 207 can target and remove acidic substances in the phosphate ester hydraulic fluid, remove acidic components and polar impurities in the oil, thereby achieving the purpose of reducing the acid value and solving the problem of difficult control of the acid value of phosphate ester hydraulic fluid.

[0054] Furthermore, the inner wall of the housing 201 is symmetrically provided with two guide grooves 201a about its axis, and the guide grooves 201a are horizontally L-shaped. The guide grooves 201a and the push rod 206 are fitted together. When the push rod 206 moves along the path of the guide groove 201a to the transverse groove section, the cover plate 202 and the housing 201 are connected.

[0055] Preferably, the outer diameter of the bottom surface of the cover plate 202 is the same as the inner diameter of the housing 201, so that the top of the housing 201 can be closed by the cover plate 202. The top of the cover plate 202 is also provided with a knob for rotating the cover plate 202. The surface of the knob is provided with prismatic protrusions, so that the user can control the rotation of the cover plate 202 by the knob.

[0056] When connecting the cover plate 202 to the housing 201, first align the outer push rod 206 of the cover plate 202 with the vertical groove section of the guide groove 201a of the housing 201, then place the cover plate 202 downwards until the push rod 206 moves to the bottom of the vertical groove section of the guide groove 201a, then rotate the cover plate 202 along the horizontal groove of the guide groove 201a, and limit the connection between the cover plate 202 and the housing 201 by the engagement of the push rod 206 and the guide groove 201a.

[0057] Example 3

[0058] Reference Figure 2-7 This is the third embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that:

[0059] The regenerator mechanism 200 also includes a locking element 205 located inside the housing 201.

[0060] Specifically, the inner wall of the housing 201 is provided with two chambers 201b at the lower part of the guide groove 201a. Each chamber 201b is equipped with a locking member 205 for locking the connection between the cover plate 202 and the housing 201. The locking member 205 includes a push plate 205a vertically arranged inside the chamber 201b. The bottom of the push plate 205a is connected to a first spring 205b for elastic support. At the same time, a retaining plate 205c is provided on the outer side of the push plate 205a. A round hole is provided in the middle of the retaining plate 205c, through which a round rod in the chamber 201b passes, allowing the retaining plate 205c to rotate around the round rod. Meanwhile, the outer wall of the cover plate 202 is provided with a retaining groove 202a that cooperates with the retaining plate 205c, so that the retaining plate 205c and the retaining groove 202a can be engaged.

[0061] Preferably, the top of the push plate 205a is provided with a wedge-shaped inclined surface that slopes upward along the moving path of the push rod 206. At the same time, the top of the push plate 205a extends into the guide groove 201a. When the push rod 206 moves along the transverse groove section of the guide groove 201a, the inclined surface at the top of the push plate 205a can be used to squeeze the push plate 205a, so that the push plate 205a moves downward and the first spring 205b is in a compressed state, thereby acting on the clamping plate 205c. When the push rod 206 moves away from the push plate 205a, the push plate 205a can be promptly reset under the push of the first spring 205b, and the clamping plate 205c is also reset.

[0062] Furthermore, a protrusion is provided on the lower inner side of the push plate 205a, and a protrusion that cooperates with the push plate 205a is also provided on the lower side of the clamping plate 205c near the push plate 205a. That is, when the push plate 205a moves down, the clamping plate 205c can be pushed by the push plate 205a to rotate its lower part outward into the inside of the clamping groove 202a with the cooperation of the two protrusions, thereby completing the engagement between the clamping plate 205c and the clamping groove 202a and locking the connection between the cover plate 202 and the housing 201. It should be noted that the overall length of the clamping groove 202a is greater than the width of the clamping plate 205c to meet the space requirements when the clamping plate 205c gradually rotates out under the downward push of the push plate 205a. That is, during the rotation of the cover plate 202, the smooth rotation of the lower end of the clamping plate 205c is not affected.

[0063] Furthermore, the top of the push plate 205a is provided with a groove 205a-1. The bottom surface of the groove 205a-1 is arc-shaped. The groove 205a-1 on the arc-shaped bottom surface can cooperate with the push rod 206. That is, when the locking plate 205c and the locking groove 202a are engaged to lock the connection between the cover plate 202 and the housing 201, the push rod 206 is at this time inside the groove 205a-1. The highest point of the groove 205a-1 can block the push rod 206 to reduce the possibility of the push rod 206 rotating outward and causing the locking plate 205c to reset, thus ensuring the stable use of the cover plate 202.

[0064] In practical use, when the push rod 206 on the outer side of the cover plate 202 reaches the bottom of the vertical groove section of the guide groove 201a, the cover plate 202 is rotated clockwise. At this time, the push rod 206 moves along the horizontal groove section of the guide groove 201a, and the push rod 206 gradually contacts the top inclined surface of the push plate 205a. As the push rod 206 continues to move, under the action of the inclined surface of the push plate 205a, the push plate 205a moves downward and compresses the first spring 205b. At this time, as the push plate 205a moves downward, the clamping plate 205c protrudes from the lower part of the push plate 205a. As the pusher gradually rotates out, after the pusher plate 205a has completely moved down, the locking plate 205c engages with the outer wall groove 202a of the cover plate 202, locking the connection between the cover plate 202 and the housing 201. Simultaneously, the push rod 206 passes the highest point of the groove 205a-1 at the top of the pusher plate 205a and moves into the groove 205a-1. The groove 205a-1 limits the push rod 206, keeping the cover plate 202 stationary. When it is necessary to regenerate the filter element 207 inside the housing 201... When replacing, the push rod 206 can be rotated counterclockwise. The push rod 206 first moves to the outside of the groove 205a-1, and as the push rod 206 moves along the guide groove 201a, it gradually moves away from the push plate 205a. Then, the push plate 205a can move upward and reset under the elastic force of the first spring 205b. At the same time, the protrusion on the outer side of the push plate 205a can push the retaining plate 205c to reset during the upward movement, so that the retaining plate 205c and the retaining groove 202a are separated, thereby releasing the cover plate 202 and the housing 201. The locking mechanism between the housing 201 and the cover plate 202 is such that when the push rod 206 rotates with the cover plate 202 to the connection point between the horizontal and vertical grooves of the guide groove 201a, the cover plate 202 can be lifted to remove it, and then the regenerated filter element 207 can be replaced. Through the cooperation between the push rod 206 and the locking element 205, the locking and unlocking of the connection between the housing 201 and the cover plate 202 can be completed during the rotation of the cover plate 202. Compared with the traditional flange connection method, this makes the replacement of the regenerated filter element 207 simpler and faster, reducing the workload of the user.

[0065] Example 4

[0066] Reference Figure 2-8 This is the fourth embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that:

[0067] The regenerator mechanism 200 also includes lugs 203 symmetrically arranged on the outer edge of the top plate of the cover plate 202, and each lug 203 has a positioning member 204 penetrating through its interior.

[0068] Specifically, the positioning component 204 includes a bottom ring 204a fixed to the outer wall of the housing 201, and a second spring 204b is symmetrically arranged on the surface of the bottom ring 204a. A lifting ring 204c sleeved on the outside of the housing is fixedly connected to the top of the second spring 204b. At the same time, a positioning rod 204d that can pass through the lug 203 is fixed on the surface of the lifting ring 204c.

[0069] Furthermore, the inner side of the lifting ring 204c is provided with an inwardly extending protrusion, and the outer wall of the housing 201 is provided with a sliding groove that cooperates with the protrusion. The lifting trajectory of the lifting ring 204c is restricted by the cooperation between the protrusion and the sliding groove, so as to ensure that the positioning rod 204d can be smoothly inserted into the lug 203 to complete the restriction of the cover plate 202.

[0070] In practical use, when installing and connecting the cover plate 202, first press the lifting ring 204c downward to prevent the positioning rod 204d from being in the rotation path of the cover plate 202. After the cover plate 202 is connected to the housing 201, the lifting ring 204c is reset under the elastic force of the second spring 204b, thereby causing the positioning rod 204d to be inserted into the lug 203. The positioning rod 204d restricts the cover plate 202, preventing the cover plate 202 from rotating again during installation and causing the locking plate 203c to release the lock on the cover plate 202. Through the cooperation between the positioning part 204 and the lug 203, the stability of the cover plate 202 when connected to the housing 201 is ensured, thereby further optimizing the connection effect between the cover plate 202 and the housing 201.
