Description

Technical Field

[0001] The invention relates to the technical field of filtration, in particular to a dewaxing filter for decolorized oil processing. Background Art

[0002] During the filtration of decolorized oil, the state of the filter in the equipment is crucial. During filtration, if the temperature and viscosity of the filtered liquid deviate, whether it is too high or too low, it will have a significant impact on the normal operation of the filter; when the filter is no longer in a horizontal state after long-term use, that is, it is deformed, it will cause a series of serious problems.

[0003] First, the filtration efficiency will be greatly reduced. Since the filter is no longer horizontal, the liquid cannot pass through the filter evenly, causing the filtration pressure in some areas to increase sharply, while the filtration effect in other areas is significantly weakened, ultimately leading to a serious decline in the overall filtration efficiency.

[0004] Secondly, the filter is very easy to be damaged. The pressure distribution on the non-level filter is extremely uneven, which may cause excessive local force concentration on the filter, causing the filter to be damaged or even seriously deformed, greatly shortening the service life of the filter.

[0005] Finally, the flow of the fluid will be severely obstructed. The uneven filter screen will produce uneven resistance when the liquid passes through, which may cause the flow of the local fluid to stagnate, seriously affecting the stability and flow of the overall filtration system, causing great trouble to production.

[0006] Therefore, the present invention proposes a dewaxing filter for bleached oil processing, which can detect filter deformation; perform temporary maintenance after detection; increase the flow rate of the fluid in the filter cavity through the filter; provide feedback on pressure changes in the filter cavity caused by temperature; and monitor the temperature of each position of the fluid in the filter cavity, to solve the above-mentioned problems. Summary of the invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose a dewaxing filter for decolorized oil processing to solve the problems existing in the prior art.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dewaxing filter for decolorizing oil processing, comprising: a filter cavity, side wall auxiliary parts, a filter screen and a temperature sensor, the dewaxing filter for decolorizing oil processing also comprises: a driving component, an auxiliary component, a filter screen detection component, the driving component, the auxiliary component and the filter screen detection component are on the same horizontal plane; the driving component comprises an A telescopic rod; the auxiliary component comprises an expansion capsule for fixing and for temperature and pressure feedback in the filter cavity; the filter screen detection component comprises a square cavity and a T-shaped component sliding on the square cavity.

[0009] Preferably, the drive assembly also includes an A-driven telescopic body fixed in the side wall auxiliary component, the A-driven telescopic rod is telescopically arranged in the A-driven telescopic body, the A-driven telescopic rod is equidistantly provided with through holes, and the side wall of the A-driven telescopic body is fixedly connected to an air pump.

[0010] Preferably, the auxiliary component also includes an air pipe fixedly connected to the A-driving telescopic body, a fixed spring body is fixedly connected to the air pipe, a non-fixed end of the fixed spring body is fixedly connected to a disc, the disc slides in the air pipe, and a scale line is fixedly provided above the air pipe and on the side wall of the A-driving telescopic body.

[0011] Preferably, the outer walls on both sides of the A telescopic rod are fixedly connected with side wall bags, the end of the trachea away from the air pump is fixedly connected with an expansion bag, the expansion bag is fixedly connected with plug-in columns on both sides, and a fixing port is provided on the outer side of the plug-in column.

[0012] Preferably, the T-shaped piece is fixedly connected to the outer end of telescopic rod A, the fixing opening is symmetrically opened in the T-shaped piece, an auxiliary spring and a push switch are fixedly connected to the upper surface of the T-shaped piece, and the auxiliary spring and the push switch are arranged at intervals.

[0013] Preferably, a B-driven telescopic body is fixedly connected to the square cavity, and a B-driven telescopic rod is telescopically arranged on the B-driven telescopic body. The B-driven telescopic body can drive the B-driven telescopic rod to perform telescopic movement, thereby realizing detection and support of the filter.

[0014] Preferably, the front end of the side wall bag is connected to the trachea through a connecting tube. The connection between the side wall bag and the trachea can realize gas transfer and pressure balance, and can also provide feedback on the pressure / temperature inside the device.

[0015] Preferably, the expansion bladder is configured to be corrugated, and the corrugated design can increase the elasticity and deformation capacity of the expansion bladder, so that it can better adapt to changes in temperature and pressure.

[0016] Preferably, a slide groove matched with the T-shaped piece is provided on the square cavity, and the T-shaped piece can slide in the slide groove to guide and limit the square cavity.

[0017] Preferably, the inner side surface of the B-driven telescopic body is designed to be arc-shaped, and the inner side surface of the arc can reduce the resistance between the B-driven telescopic body and the fluid, thereby increasing the flow rate of the fluid through the filter.

[0018] Compared with the prior art, the present invention provides a dewaxing filter for decolorizing oil processing, which has the following beneficial effects: 1. Through the setting of the B-driven telescopic body and the B-telescopic rod, when the filter detection component detects that the filter is deformed due to high temperature / fluid viscosity, support can be provided for the filter, and the deformed filter can be temporarily assisted to restore to the state before deformation, thereby ensuring that the filter can effectively filter the fluid.

[0019] At the same time, since the inner side of the B-driven telescopic body is designed to be arc-shaped during design, when the two B-driven telescopic bodies move away from each other during detection of the filter, the B-driven telescopic body can disturb the fluid in the filter cavity. At this time, the fluid will form a boundary condition under the action of the moving arc surface of the B-driven telescopic body. The fluid will flow along the surface of the B-driven telescopic body, thereby forming a vortex, thereby increasing the flow rate of the fluid through the filter.

[0020] 2. The setting of the expansion capsule can not only sense temperature changes, but also is different from the existing technology which lacks efficient perception and feedback mechanism of temperature changes of the fluid in the filter cavity. It uses an air pump to inflate and push the plug-in column for fixation, providing guarantee for the subsequent support work of the B telescopic rod, and realizing the effective fixation and support function after the deformation of the filter is detected.

[0021] At the same time, when the temperature is too high, causing the distance between gas molecules in the expansion capsule to increase, pushing the disc to move, the temperature and the pressure changes caused by the temperature can be fed back more promptly. This feedback mechanism is more sensitive and accurate, allowing operators to obtain relevant information more quickly, thereby adjusting operations in time to ensure the normal operation and filtration effect of the filter.

[0022] In addition, the corrugated design of the expansion bladder increases its elasticity and deformation capacity, enabling it to better adapt to changes in temperature and pressure, improving the stability and reliability of the equipment, which is different from the instability of existing detection sensors at high temperatures; and the synergy between the expansion bladder and other components such as the trachea and side wall bladder forms a complete temperature and pressure monitoring and feedback system with a high degree of integration and optimization.

[0023] 3. Through the setting of the square cavity and the T-shaped piece, when it is indirectly driven by the driving assembly to move horizontally, the B-driven telescopic body and the B-telescopic rod connected thereto will change the contact state and relative position with the filter during the movement; if the filter is deformed, the B-driven telescopic body and the B-telescopic rod that originally moved horizontally will be forced to move downward under the restriction of the deformed and downwardly concave filter, so that the push switch on the T-shaped piece will be pressed, and at this time it can be effectively detected whether the filter is deformed due to excessive resistance when passing through the filter due to excessively high temperature / viscosity of the fluid. This detection of the filter can effectively ensure the effectiveness of filtering the fluid through the filter. Compared with the prior art, our technology sets a detection operation for whether the filter is deformed during the filtration process, avoiding the situation where blind filtration leads to the inability to observe whether the filter is deformed, thereby ensuring the realization of the filtration effect.

[0024] 4. Through the setting of the driving component, in addition to providing the working prerequisites for the auxiliary components and the filter detection components, the driving component can also indirectly drive the temperature sensor installed thereon to move when driving the square cavity to move. This is different from the temperature monitoring method in the prior art in which the temperature sensor is fixed in the filter cavity and does not move. This method of driving the temperature sensor to move in the fluid can effectively monitor the fluid temperature at various positions in the filter cavity, avoiding the situation in the prior art where the temperature monitoring position is single and the monitoring effect is poor.

[0046] The auxiliary component 5 also includes an air pipe 501 fixedly connected to the A-driving telescopic body 401, a fixed spring body 502 is fixedly connected inside the air pipe 501, a non-fixed end of the fixed spring body 502 is fixedly connected to a disc 503, the disc 503 slides in the air pipe 501, and a scale line 504 is fixedly provided above the air pipe 501 and on the side wall of the A-driving telescopic body 401.

[0047] The outer walls of both sides of the telescopic rod 402 are fixedly connected with side wall bags 505, and the end of the air tube 501 away from the air pump 404 is fixedly connected with an expansion bag 506. The expansion bag 506 is fixedly connected with plug-in columns 507 on both sides, and a fixing port 508 is provided on the outer side of the plug-in column 507.

[0048] The T-shaped piece 602 is fixedly connected to the outer end of the A telescopic rod 402, and the fixing port 508 is symmetrically opened in the T-shaped piece 602. The upper surface of the T-shaped piece 602 is fixedly connected with an auxiliary spring 603 and a push switch 604. The auxiliary spring 603 and the push switch 604 are arranged at intervals. The square cavity 601 is fixedly connected with a B driving telescopic body 605, and a B telescopic rod 606 is telescopically arranged on the B driving telescopic body 605. The B driving telescopic body 605 can drive the B telescopic rod 606 to perform telescopic movement, thereby realizing the detection and support of the filter 2.

[0049] Among them: the temperature sensor 3 is mainly used for monitoring the temperature of the fluid in the filter chamber 1.

[0050] The driving component 4 is mainly used to provide working conditions for the auxiliary component 5 and the filter screen detection component 6 , and can also indirectly drive the temperature sensor 3 to move in the filter chamber 1 .

[0051] The through hole 403 is mainly used to allow the fluid in the filter chamber 1 to pass through when the A telescopic rod 402 extends from the A driving telescopic body 401.

[0052] The air pump 404 is mainly used to provide power for the expansion of the expansion bag 506 through the trachea 501 .

[0053] The auxiliary component 5 is mainly used for auxiliary functions, to provide feedback on the pressure magnitude caused by the temperature in the filter chamber 1, and to provide a stable premise for the B telescopic rod 606 in the filter detection component 6 when used as a support member.

[0054] The disc 503 and the air tube 501 are slidably fitted.

[0055] The scale line 504 is mainly used for position feedback when the temperature in the filter chamber 1 is too high, causing the expansion capsule 506 and the gas temperature in the air pipe 501 to be too high, resulting in an increase in the molecular distance pushing the disc 503 to move.

[0056] The side wall bag 505 is mainly used to assist the expansion bag 506 to sense the temperature change of the fluid in the filter cavity 1. The front end of the side wall bag 505 is connected to the air pipe 501 through a connecting tube. The connection between the side wall bag 505 and the air pipe 501 can realize the gas transfer and pressure balance, and at the same time, the internal pressure / temperature of the device can be fed back.

[0057] The expansion bladder 506 is configured to be corrugated, and the corrugated design can increase the elasticity and deformation capacity of the expansion bladder 506, so that it can better adapt to changes in temperature and pressure.

[0058] The plug-in column 507 is plugged and matched with the fixing port 508 , and is mainly used to fix the relative position of the square cavity 601 and the T-shaped piece 602 when the B telescopic rod 606 serves as the filter 2 maintenance function.

[0059] The filter screen detection component 6 is mainly used to detect whether the filter screen 2 is deformed during use, and to provide temporary maintenance after deformation.

[0060] A slide groove matched with the T-shaped piece 602 is provided on the square cavity 601 , and the T-shaped piece 602 can slide in the slide groove to guide and limit the square cavity 601 .

[0061] The push switch 604 is electrically connected to the main control of the device. When the push switch 604 is pressed, the main control will generate information to notify the corresponding staff.

[0062] The inner side surface of the B-driven telescopic body 605 is designed to be arc-shaped, and the arc-shaped inner side surface can reduce the resistance between the B-driven telescopic body 605 and the fluid, thereby increasing the flow rate of the fluid passing through the filter screen 2.

[0063] When not in use, the square cavity 601 is closely attached to the inner wall of the filter cavity 1 .

[0064] The working principles of all the contents in the above embodiments are as follows: in the initial state: B drives the telescopic body 605 to be close to the inner wall of the filter chamber 1, the spring body on the fixed spring body 502 is not stretched, the plug-in column 507 is not plugged into the fixed port 508, the auxiliary spring 603 is not compressed, and the push switch 604 is not pressed.

[0065] The following is the working process of the driving component 4: when in use, start the device, the A driving telescopic body 401 will drive the A telescopic rod 402 to extend from itself, thereby indirectly driving the B driving telescopic body 605 at the outer end of the A telescopic rod 402 to move, and check the filter 2; further, the air pump 404 will charge the air pipe 501 and the expansion bag 506 and the side wall bag 505 connected to the air pipe 501 with gas when in use.

[0066] Furthermore, through the setting of the driving component 4, the driving component 4 not only provides the working premise for the auxiliary component 5 and the filter detection component 6; the driving component 4 can also indirectly drive the temperature sensor 3 set thereon to move when driving the square cavity 601 to move. This is different from the temperature monitoring method in the prior art where the temperature sensor 3 is fixed in the filter cavity 1 and does not move. This method of driving the temperature sensor 3 to move in the fluid can effectively monitor the fluid temperature at various positions in the filter cavity 1, avoiding the situation in the prior art where the temperature monitoring position is single and the monitoring effect is poor.

[0067] Please refer to the above working process Figures 1 to 3 .

[0068] The following is the working process of the auxiliary component 5: Furthermore, after the filter detection component 6 detects that the filter 2 is deformed, the auxiliary component 5 can fix the relative position of the square cavity 601 and the T-shaped piece 602, thereby indirectly driving the B-driven telescopic body 605 and the B telescopic rod 606 extending therefrom to provide temporary support assistance to the deformed filter 2.

[0069] Specifically, when the air pump 404 is started, the gas entering the air pipe 501 will push the slidingly connected disc 503 in the air pipe 501. When the disc 503 moves, the gas in the air pipe 501 will enter the expansion bag 506. The gas entering the expansion bag 506 will cause the plug-in columns 507 on both sides to move to both sides, so as to be plugged into the fixed port 508 opened on the square cavity 601. At this time, the relative position of the square cavity 601 and the T-shaped piece 602 cannot be moved. At this point, the B drive telescopic body 605 and the B telescopic rod 606 extending therefrom can temporarily support the deformed filter 2 under the drive of the drive component 4.

[0070] Furthermore, the setting of the expansion bag 506 is not only capable of sensing temperature changes, but also different from the problem of the lack of efficient sensing and feedback mechanism for the temperature changes of the fluid in the filter chamber 1 in the prior art. It is fixed by inflating the plug-in column 507 through the air pump 404, providing guarantee for the subsequent support work of the B telescopic rod 606, and realizing the effective fixing and supporting function after the deformation of the filter 2 is detected.

[0071] At the same time, when the temperature is too high, causing the distance between gas molecules in the expansion capsule 506 to increase, pushing the disc 503 to move, the temperature and the pressure changes caused by the temperature can be fed back more promptly. This feedback mechanism is more sensitive and accurate, allowing operators to obtain relevant information more quickly, thereby adjusting operations in time to ensure the normal operation and filtering effect of the filter.

[0072] In addition, the corrugated design of the expansion bag 506 increases its elasticity and deformation capacity, enabling it to better adapt to changes in temperature and pressure, improving the stability and reliability of the equipment, which is different from the instability of existing detection sensors at high temperatures; and, the synergistic effect of the expansion bag 506 with other components such as the trachea 501 and the side wall bag 505 forms a complete temperature and pressure monitoring and feedback system with a high degree of integration and optimization.

[0073] Please refer to the above working process Figures 1 to 3 , Figures 7 to 9 .

[0074] The following is the working process of the filter detection assembly 6: When in use, when the filter detection assembly 6 driven by the driving assembly 4 passes through the bottom surface of the filter 2, if the filter 2 is deformed, such as Figure 2 As shown, at this time, the square cavity 601 will be against the protruding bottom surface of the filter 2. As the driving component 4 is further driven to move, the square cavity 601 will move downward under the guidance of the T-shaped piece 602 during the pressure. At this time, the auxiliary spring 603 and the push switch 604 are both pressed. Since it is known that the push switch 604 is electrically connected to the main control of the device, when the push switch 604 is pressed, the main control will generate information to notify the corresponding staff. Therefore, at this time, the operator of the filter device will know that the filter 2 is deformed.

[0075] Furthermore, through the setting of the B-driven telescopic body 605 and the B telescopic rod 606, in addition to indirectly driving the B telescopic rod 606 to move when the filter detection component 6 is working, this movement changes the contact state and relative position of the B telescopic rod 606 and the filter 2, so that the detection component can sense the state change of the filter 2, thereby triggering the start condition of the filter 2 detection; when the filter detection component 6 detects that the filter 2 is deformed due to high temperature / fluid viscosity, it can also provide support for the filter 2, temporarily assisting the deformed filter 2 to restore the state before deformation, thereby ensuring that the filter 2 can effectively filter the fluid.

[0076] At the same time, since the inner side surface of the B-driven telescopic body 605 is designed to be arc-shaped during design, when the two B-driven telescopic bodies 605 detect the filter 2 and move away from each other, the B-driven telescopic body 605 can cause disturbances in the fluid in the filter cavity 1. At this time, the fluid will form a boundary condition under the action of the arc surface of the moving B-driven telescopic body 605, and the fluid will flow along the surface of the B-driven telescopic body 605, thereby forming a vortex, thereby increasing the flow rate of the fluid through the filter 2.

[0077] Furthermore, through the arrangement of the square cavity 601 and the T-shaped piece 602, when it is indirectly driven by the driving assembly 4 to move horizontally, the B-driven telescopic body 605 and the B-telescoping rod 606 connected thereto will change the contact state and relative position with the filter screen 2 during the movement; if the filter screen 2 is deformed, the B-driven telescopic body 605 and the B-telescoping rod 606 that originally moved horizontally will be forced to move downward under the restriction of the deformed and downwardly concave filter screen 2, so that the push switch 604 on the T-shaped piece 602 will be pressed, and at this time, it can be effectively detected whether the filter screen is deformed due to excessive resistance when passing through the filter screen 2 due to excessively high temperature / viscosity of the fluid. This detection of the filter screen 2 can effectively ensure the effectiveness of filtering the fluid through the filter screen 2. Compared with the prior art, our technology sets a detection operation for whether the filter screen 2 is deformed during the filtration process, thereby avoiding the situation where blind filtration leads to the inability to observe whether the filter screen 2 is deformed, thereby ensuring the realization of the filtration effect.
