Description

TECHNICAL FIELD

[0001] The utility model relates to a filter belongs to filter technical field. BACKGROUND

[0002] It is essential to use a filter on a heating and ventilation pipeline because it can effectively capture and remove impurities and foreign matter in the water circulation system, thereby preventing pipeline blockage or internal damage to the equipment caused by these pollutants, reducing the wear and tear of mechanical parts, prolonging the service life of the equipment, and improving the efficiency and performance of the entire heating, ventilation and air conditioning system. By keeping the system clean and the water flowing smoothly, the filter helps to reduce energy consumption, optimize indoor temperature control, meet the requirements of national standards, ensure safe, environmentally friendly and cost-effective operation.

[0003] The current common filter design usually only configures a single filter element for filtering. In the face of sudden high-dust environment, dust will quickly accumulate on the filter element, causing rapid saturation and blockage of the filter element. If this condition is not handled in time by disassembling and cleaning or replacing the filter element, it will cause the airflow passage to be limited, thereby affecting the air flow performance in the heating and ventilation pipeline and reducing the efficiency and effectiveness of the entire heating, ventilation and air conditioning system.

[0004] In summary, the filter of the prior art usually only configures a single filter element for filtering. In the face of sudden high-dust environment, it is not convenient to disassemble and clean or replace the filter element in time, which can easily cause blockage of the filter element, causing the airflow passage to be limited, thereby affecting the air flow performance in the heating and ventilation pipeline and reducing the efficiency and effectiveness of the entire heating, ventilation and air conditioning system. SUMMARY

[0005] The utility model discloses a filter, belonging to filter technical field.

[0006] To solve the above technical problems, the utility model is realized by adopting the following technical scheme:

[0007] The utility model provides a filter, including installation pipeline and installation box that sets up in the installation pipeline outer wall, be equipped with multiple sets of filter components in the installation pipeline,

[0008] The filter assembly includes a first mounting frame disposed within the installation pipe, a second mounting frame movably connected to the side wall of the first mounting frame, a filter mechanism disposed within the second mounting frame, a sliding seat slidably connected to one side of the second mounting frame on the side wall of the mounting box, one end of the second mounting frame penetrating the outer wall of the installation pipe and fixedly connected to the sliding seat, the sliding seat being elastically connected to the side wall of the mounting box via an elastic pull rope, and a limiting component for limiting the second mounting frame on the first mounting frame.

[0009] The above technical solution, through the cooperation of the second mounting frame, elastic pull rope, slide, and limiting component, allows one set of filter components to perform the main filtration work during normal operation. When this filter component faces a sudden high dust environment and needs to be disassembled and replaced, the limiting mechanism can be controlled to release the limiting work on the second mounting frame. At this time, the elastic pull rope can pull the slide to move, thereby driving the corresponding second mounting frame to move into the interior of the mounting box, thus directly retracting the blocked filter component. At this time, another set of filter components adjacent to it in the installation pipe can replace it to perform filtration work, thereby avoiding the blockage of the filter component and ensuring the airflow performance in the HVAC duct.

[0010] Optionally, the limiting component includes a mounting groove formed on the side wall of the first mounting frame near the second mounting frame. A slidingly connected locking block is provided in the mounting groove. The locking block is elastically connected to the inner wall of the mounting groove by a spring. A traction rope is provided on the outer wall of the locking block on the side of the spring. A power mechanism is provided on the outer wall of the mounting pipe on the side of the first mounting frame. The output end of the power mechanism is fixedly connected to the traction rope. A locking groove is formed on the outer wall of the second mounting frame on the side of the locking block. The locking block cooperates with the locking groove to fix the relative position of the first mounting frame and the second mounting frame.

[0011] The above technical solution, through the cooperation of the slot and the block, ensures that during normal operation, the block is located inside the slot, fixing the positions of the first and second mounting frames and preventing the elastic pull rope and slide from moving the second mounting frame. When the filter mechanism inside the second mounting frame becomes clogged, the power mechanism can drive the traction rope to move, thereby pulling the block towards the mounting slot, so that the block moves to the outside of the slot to facilitate the operation of the elastic pull rope. When the power mechanism drives the traction rope to return to its original state, the spring can push the block back to its original position to facilitate the next limiting operation.

[0012] Optionally, the power mechanism includes an electric actuator.

[0013] The above technical solution uses an electric push rod to drive the traction rope, ensuring the stability of the traction rope during movement.

[0014] Optionally, a pressure sensor is provided on the outer wall of the first mounting frame near the second mounting frame, and the pressure sensor is electrically connected to the limiting component.

[0015] In the above technical solution, when the filter mechanism becomes clogged, the wind force it receives increases, which in turn increases the pressure on the pressure sensor. When the pressure reaches a threshold, the pressure sensor controls the power mechanism to extend and retract, thereby driving the locking block to move and canceling the limit on the second mounting frame to complete the storage of the second mounting frame. By monitoring the pressure difference before and after the filter mechanism in real time and automatically canceling the limit on the second mounting frame, the switching of the filter mechanism is completed, ensuring the continuity of airflow and the stability of the system.

[0016] Optionally, a through groove is provided on the inner wall of the installation pipe on one side of the second installation frame, and the through groove is used to guide the lifting and lowering of the second installation frame.

[0017] The above technical solution guides the lifting and lowering of the second mounting frame through the through groove, and also limits the movement of the second mounting frame to a certain extent, thus ensuring the stability of the movement of the second mounting frame.

[0018] Optionally, the filtration mechanism includes a plate filter element.

[0019] The above technical solution uses plate filter elements for filtration, which facilitates the cleaning and replacement of the filtration mechanism.

[0020] Optionally, a sealing plate is provided on the outer wall of the second mounting frame near the side of the first mounting frame.

[0021] In the above technical solution, when the plate filter element moves into the mounting box, the sealing plate adheres to the bottom inner wall of the first mounting frame, thereby achieving a sealing effect.

[0022] Optionally, a rubber block is provided between the second mounting frame and the slide.

[0023] The above technical solution uses rubber blocks to cushion the movement of the second mounting frame. The rubber blocks have a certain degree of elasticity, which allows the second mounting frame to move slightly, ensuring that the second mounting frame fits snugly against the first mounting frame during operation.

[0024] Optionally, the inner wall of the mounting box is detachably connected to a cover plate.

[0025] The above technical solution allows for the removal of the inner cover of the mounting box after the plate filter element enters the mounting box, enabling the replacement or cleaning of the plate filter element inside the mounting box, thus ensuring the convenience of the device.

[0026] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0027] 1. This utility model, through the cooperation of a second mounting frame, elastic pull rope, limiting component and slide, allows the limiting mechanism to be released from the second mounting frame when the filter component faces a sudden high dust environment and its filter mechanism needs to be disassembled and replaced. The elastic pull rope pulls the slide to move, thereby moving the filter mechanism in the second mounting frame into the inside of the mounting box, thus directly retracting the blocked filter component. At this time, another set of filter components adjacent to it in the installation pipe can be replaced to perform the filtration work, thereby quickly completing the replacement of the filter component. It can effectively prevent the filter mechanism from being severely blocked and affecting the airflow in the HVAC pipe, ensuring the airflow performance in the HVAC channel, and ensuring the efficiency and effect of the entire heating, ventilation and air conditioning system.

[0028] 2. This utility model, by integrating multiple independent filter components and a pressure sensor, excels in improving air filtration efficiency and convenience. Its automatic detection and response mechanism monitors the pressure difference before and after the plate filter element in real time and automatically switches to a backup plate filter element to avoid clogging, ensuring the continuity of airflow and system stability. In addition, the system has a stronger ability to adapt to high-dust environments, is easier to maintain, and effectively saves energy and costs by reducing manual intervention and optimizing system operation. At the same time, the automated maintenance process reduces operational risks and improves system safety. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0035] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] Example 1:

[0038] like Figures 1-4 As shown, this utility model provides a filter, including an installation pipe 1 and an installation box 5 disposed on the outer wall of the installation pipe 1. The installation pipe 1 is provided with multiple sets of filter components. The filter components include a first installation frame 2 disposed in the installation pipe 1, a second installation frame 3 movably connected to the side wall of the first installation frame 2, a filter mechanism disposed in the second installation frame 3, and a sliding seat 7 slidably connected to the side wall of the installation box 5 on one side of the second installation frame 3. One end of the second installation frame 3 passes through the outer wall of the installation pipe 1 and is fixedly connected to the sliding seat 7. The sliding seat 7 is elastically connected to the side wall of the installation box 5 by an elastic pull rope 6. The first installation frame 2 is provided with a limiting component for limiting the second installation frame 3.

[0039] Specifically, the mounting box 5 is fixed to the bottom of the mounting pipe 1, which is installed between two sections of HVAC pipe. Multiple filter components are vertically installed inside the mounting pipe 1. The filter component that comes into contact with the air first serves as the main filter, while the others serve as backup filters. During operation, air circulates between the two sections of HVAC pipe and the mounting pipe 1. At this time, the filter component closest to the airflow direction plays a primary filtering role. For this filter component, the second mounting frame 3 is installed on one side of the first mounting frame 2, and the filtering mechanism inside the second mounting frame 3 performs the filtering function. At this time, the limiting mechanism limits the second mounting frame 3 to ensure the stability of its position and to ensure the stability of the second mounting frame 3. Regarding the filtration effect of the internal filtration mechanism, when the filtration mechanism has been working for a long time, or in a sudden high-dust environment, the filtration mechanism becomes clogged and needs to be disassembled and replaced. At this time, the limiting component on one side of the filtration mechanism starts to work, canceling the limiting work on the second mounting frame 3. After the second mounting frame 3 is unblocked, the corresponding elastic pull rope 6 can drive the slide 7 away from the installation pipe 1. The second mounting frame 3 moves with the slide 7, thereby moving the second mounting frame 3 into the interior of the mounting box 5 for storage, completing the storage of this filtration component. At this time, the other filtration component closest to the airflow direction can replace the original filtration component to play the main filtration role, ensuring that this utility model can continuously perform filtration work.

[0040] This utility model, through the cooperation of the second mounting frame 3, elastic pull rope 6, limiting component and slide 7, allows the limiting mechanism to be released from the second mounting frame 3 when the filter component faces a sudden high dust environment and its filter mechanism needs to be disassembled and replaced. The elastic pull rope 6 pulls the slide 7 to move, thereby moving the filter mechanism in the second mounting frame 3 into the mounting box 5, thus directly retracting the blocked filter component. At this time, another set of filter components adjacent to it in the installation pipe 1 can replace it to perform the filtration work, thereby quickly completing the replacement of the filter component. It can effectively prevent the filter mechanism from being severely blocked and affecting the airflow in the HVAC pipe, ensuring the airflow performance in the HVAC channel, and ensuring the efficiency and effect of the entire heating, ventilation and air conditioning system.

[0041] Example 2:

[0042] like Figure 2 and Figure 4As shown, the limiting component includes a mounting groove on the side wall of the first mounting frame 2 near the second mounting frame 3. A slidingly connected locking block 10 is provided in the mounting groove. The locking block 10 is elastically connected to the inner wall of the mounting groove via a spring 11. A traction rope 12 is provided on the outer wall of the locking block 10 on one side of the spring 11. A power mechanism is provided on the outer wall of the mounting pipe 1 on one side of the first mounting frame 2. The output end of the power mechanism is fixedly connected to the traction rope 12. A slot 301 is provided on the outer wall of the second mounting frame 3 on one side of the locking block 10. The locking block 10 cooperates with the slot 301 to fix the relative position of the first mounting frame 2 and the second mounting frame 3. Optionally, the power mechanism includes an electric push rod 13, or a cylinder or an electric telescopic rod. The filtering mechanism includes a plate filter element 4.

[0043] Specifically, when it is necessary to remove the fixation of the second mounting frame 3, the output end of the control electric push rod 13 retracts, thereby causing the locking block 10 to move toward the interior of the mounting groove, separating the locking block 10 from the groove 301, thus releasing the lock on the second mounting frame 3. This allows the slide block 7 to move downward under the tension of the elastic pull rope 6, thereby moving the clogged plate filter element 4 into the mounting box 5. Taking the airflow direction from right to left as an example, this allows the plate filter element 4 on the left side to work. At the same time, the plate filter element 4 inside the mounting box 5 can be replaced. After replacement, the plate filter element 4 is pushed upward, allowing the locking block 10 to re-engage in the groove 301 on the second mounting frame 3. This allows the plate filter element 4 to be quickly removed after it becomes clogged, enabling the plate filter element 4 on the left side to work. This effectively prevents the plate filter element 4 from being severely clogged and affecting the airflow in the HVAC duct.

[0044] like Figure 2 As shown, in this embodiment, a pressure sensor 9 is provided on the outer wall of the first mounting frame 2 near the second mounting frame 3. The pressure sensor 9 is electrically connected to the limiting component. Optionally, the pressure sensor 9 is electrically connected to the electric push rod 13 through a PLC controller.

[0045] Specifically, when the plate filter element 4 is severely clogged, the airflow within the HVAC duct increases, causing the pressure detected by the pressure sensor 9 to increase. When the pressure reaches a threshold, the pressure sensor 9 drives the output end of the electric push rod 13 to retract via the PLC controller, thereby causing the one-way locking block 10 to move towards the interior of the mounting slot, releasing the lock on the second mounting frame 3 and moving the corresponding plate filter element 4 into the mounting box 5. This invention, by integrating multiple independent filter components and a pressure sensor 9, excels in improving air filtration efficiency and convenience. Its automatic detection and response mechanism monitors the pressure difference before and after the plate filter element 4 in real time and automatically switches to a backup plate filter element 4 to avoid clogging, ensuring the continuity of airflow and system stability. Furthermore, the system is more adaptable to high-dust environments, easier to maintain, and effectively saves energy and costs by reducing manual intervention and optimizing system operation. At the same time, the automated maintenance process reduces operational risks and improves system safety.

[0046] In this embodiment, a through groove 15 is provided on the inner wall of the installation pipe 1 on one side of the second installation frame 3. The through groove 15 is used to guide the lifting and lowering of the second installation frame 3 and at the same time provides a certain support for the second installation frame 3 to prevent the second installation frame 3 from shaking when it is located on one side of the first installation frame 2.

[0047] like Figure 2 As shown in this embodiment, a sealing plate 14 is provided on the outer wall of the second mounting frame 3 near the side of the first mounting frame 2. When the plate filter element 4 moves into the mounting box 5, the sealing plate 14 adheres to the bottom inner wall of the first mounting frame 2, thereby achieving a sealing effect.

[0048] In this embodiment, a rubber block 8 is provided between the second mounting frame 3 and the slide block 7, which can buffer the lifting and lowering of the second mounting frame 3. At the same time, the rubber block 8 has a certain elasticity, which allows the second mounting frame 3 to move slightly, ensuring that the second mounting frame 3 can fit in position with the first mounting frame 2 when the filtration is working.

[0049] In this embodiment, the inner wall of the mounting box 5 is detachably connected to a cover plate 16. When the plate filter element 4 enters the mounting box 5, the cover plate 16 on the inner wall of the mounting box 5 can be detached to replace or clean the plate filter element 4, ensuring the convenience of this utility model. Optionally, there are two cover plates 16 and they are distributed on both sides of the inner wall of the mounting box 5.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
