Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of flushing devices, and particularly relates to a flushing device for a large-flow filter element. Background Art
[0002] A filter element is a professional term for a filtering and purifying function. It is a simple device for purifying the resources of the original fluid and separating the resources. At present, filter elements are mainly used in filtering industries such as oil filtration, air filtration, and water filtration. The filter element separates solid particles in a liquid or gas, or enables different substance components to come into full contact, shortening the reaction time, and can protect the normal operation of equipment or the cleanliness of the air. For a large-flow filter element, it needs to be cleaned regularly, and a flushing device is required during cleaning.
[0003] Although there are various current flushing devices, there are still some problems. For example, the current flushing device generally has a slidable support plate driving a spray head into the filter element for flushing operations. When the support plate slides, a gear-rack linkage structure is mostly used. During the linkage, as the rack slides, the gear will abut against the end point of the rack. At present, in order to avoid wear at the end point of the gear and the rack, a servo motor is generally used for precise control, but the cost of the servo motor itself and its operation cost are relatively high, resulting in an increase in the flushing cost. Content of the Utility Model

The flushing spray head is arranged at one end of the sliding seat close to the large-flow filter element;
[0008] The linkage mechanism includes a rack, and the rack is fixed on the top of the limiting block and is slidably connected to the base through the limiting block.

[0023] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment 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. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0024] An embodiment of the present utility model provides a flushing device for a high-flow filter element, as Figures 1-5 shown, including: a high-flow filter element 1, a base 2, a flushing mechanism 3, and a linkage mechanism 4;
[0025] The high-flow filter element 1 is placed on one side of the base 2, the flushing mechanism 3 is arranged at the bottom of the base 2, the linkage mechanism 4 is arranged at the top of the base 2, and part of it is connected to the flushing mechanism 3;
[0026] The flushing mechanism 3 includes a sliding seat 31, a flushing nozzle 32, a limiting block 33, and a chute 34. The sliding seat 31 is slidably connected to the bottom of the base 2 through the limiting block 33. The chute 34 is arranged at the center of the base 2. The limiting block 33 is fixed at the center of the top of the sliding seat 31 and is slidably clamped in the chute 34. The flushing nozzle 32 is arranged at one end of the sliding seat 31 close to the high-flow filter element 1;
[0027] The linkage mechanism 4 includes a rack 41. The rack 41 is fixed to the top of the limit block 33 and is slidably connected to the base 2 through the limit block 33.
[0028] It should be noted that since the existing flushing device generally has a slidable support plate to drive the spray head into the filter element for flushing operations, and the support plate mostly uses a gear-rack linkage structure when sliding. During the linkage, as the rack slides, the gear will abut against the end point of the rack. Currently, in order to avoid wear at the end point of the gear and the rack, a servo motor is generally used for precise control. However, the cost of the servo motor itself and its operating cost are relatively high, resulting in an increase in the flushing cost. To solve this problem, a flushing mechanism 3 and a linkage mechanism 4 are provided in this solution. The inside of the large-flow filter element 1 is flushed by the flushing spray head 32 in the flushing mechanism 3. During flushing, the flushing mechanism 3 is driven by the linkage mechanism 4 to slide on the base 2, so that the flushing spray head 32 can deeply flush the inside of the large-flow filter element 1. When the linkage mechanism 4 is linked, when the end point of the rack 41 is docked with the gear 44, the gear 44 can continue to cooperate through the sliding of the linkage tooth plate 45, avoiding wear between the gear 44 and the rack 41 and causing unnecessary losses. At the same time, it also avoids the use of equipment with high costs such as servo motors or stepper motors, effectively reducing the operating cost.
[0029] Specifically, in this embodiment, this solution mainly includes a large-flow filter element 1, a base 2, a flushing mechanism 3, and a linkage mechanism 4. When in use, the large-flow filter element 1 is arranged on one side of the base 2, and then the inside of the large-flow filter element 1 is flushed by the flushing mechanism 3, and the flushing mechanism 3 is driven by the linkage mechanism 4 to slide on the base 2. During the linkage, the rack 41 is driven by the gear 44 to engage and link, so that the sliding seat 31 can slide at the bottom of the base 2. When the end point of the rack 41 is docked with the gear 44, the gear 44 can continue to cooperate through the sliding of the linkage tooth plate 45.
[0030] In a further preferred embodiment of the present utility model, as Figures 1-5 shown, the linkage mechanism 4 further includes a support plate 42, a speed-regulating motor 43, and a gear 44. The support plate 42 is fixed at the center of one side of the base 2. The speed-regulating motor 43 is fixed on the support plate 42. The gear 44 is coaxially fixed to the output shaft of the speed-regulating motor 43, and the gear 44 meshes with the rack 41.
[0031] In this embodiment, the speed-regulating motor 43 drives the gear 44 to rotate, and then the gear 44 drives the rack 41 to engage and link, and slides on the base 2.
[0032] In a further preferred embodiment of the present utility model, as Figures 1-5As shown, the linkage mechanism 4 further includes a linkage tooth plate 45, a docking plate 46, and a guide rod 47. The linkage tooth plates 45 are symmetrically arranged on both sides of the rack 41. The docking plates 46 are respectively fixed on the side walls of the rack 41 and the linkage tooth plates 45. One end of the guide rod 47 is fixed to the docking plate 46 on the rack 41, and the other end is slidably connected to the docking plate 46 on the linkage tooth plate 45, and a chuck larger than the aperture of the docking plate 46 is provided at the connection end.
[0033] In this embodiment, the guide rod 47 enables the linkage tooth plate 45 to slide at one end of the rack 41. Thus, when the end point of the rack 41 is docked with the gear 44, the gear 44 can continue to cooperate through the sliding of the linkage tooth plate 45.
[0034] In a further preferred embodiment of the present utility model, as Figures 1-5 shown, a return spring 48 is sleeved on the guide rod 47, and the return spring 48 is arranged between two adjacent docking plates 46.
[0035] In this embodiment, the elastic force of the return spring 48 enables the linkage tooth plate 45 to quickly reset.
[0036] In a further preferred embodiment of the present utility model, as Figures 1-5 shown, a first stop rod 49 is fixed at the center of the side wall of the rack 41, and second stop rods 410 are symmetrically fixed on both sides of the base 2.
[0037] In this embodiment, the second stop rod 410 limits the first stop rod 49, and thus limits the rack 41 to prevent it from slipping off the base 2.
[0038] In a further preferred embodiment of the present utility model, as Figures 1-5 shown, a cavity is provided inside the sliding seat 31, and a water outlet pipe 35 is provided on one side of the bottom of the sliding seat 31, and a water inlet pipe 36 is provided on the other side. Both the water outlet pipe 35 and the water inlet pipe 36 communicate with the cavity, and the flushing nozzle 32 is detachably connected to the water outlet pipe 35 by a thread.
[0039] In this embodiment, the threaded connection enables the staff to quickly replace the flushing nozzle 32.
