Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cleaning devices, and particularly relates to a self-cleaning device for a large-flow filter element. Background Art
[0002] The large-flow filter element separates solid particles in liquids or gases, or enables different substance components to fully contact, shortening the reaction time, and can protect the normal operation of equipment or the cleanliness of air. After the large-flow filter element is used for a long time, a large amount of impurities will accumulate inside the filter element, thus affecting the purification effect. Therefore, a self-cleaning device is needed to process the filter element.
[0003] Although there are various current filter element self-cleaning devices, there are still some problems. For example, most current cleaning devices clean the filter element by means of blowing, which is coordinated by a blowing nozzle and an air compressor. The air compressor generally uses single-direction compression, that is, on one side inside the machine body, the air is continuously compressed by the piston movement. Although this compression method can achieve the compression effect of air, the amount of gas that can be compressed at one time is small, resulting in the compressor needing to continuously perform high-intensity compression operations, which easily causes damage to the compressor and thus unnecessary economic losses.

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0022] An embodiment of the present utility model provides a self-cleaning device for a large-flow filter element, as Figures 1-4 shown, including: a base 1, an air compression cylinder 2, an intake pipe 3, an outlet pipe 4, and an air compression mechanism 5;
[0023] The air compression cylinder 2 is fixed on the base 1, the intake pipe 3 is arranged on one side of the air compression cylinder 2, the outlet pipe 4 is arranged on the other side of the air compression cylinder 2, and the air compression mechanism 5 is connected to the base 1 and inside the air compression cylinder 2;
[0024] The air compression mechanism 5 includes a driving unit and a compression unit. The compression unit includes a first sealing plug 51, a second sealing plug 52, a first linkage rod 53, and a second linkage rod 54. The first sealing plug 51 and the second sealing plug 52 are both slidably connected in the inner cavity of the air compression cylinder 2 and are symmetrically arranged up and down. The first linkage rod 53 is coaxially fixed to the bottom of the first sealing plug 51. The second linkage rod 54 is coaxially fixed to the bottom of the second sealing plug 52, and through holes are provided through the centers of the second sealing plug 52 and the second linkage rod 54. The first linkage rod 53 passes through the through hole and is slidably connected in the through hole. The driving unit is arranged on the base 1.
[0025] It should be noted that, since most existing cleaning devices use a purging method to clean the filter element, they are coordinated through a purging nozzle and an air compressor, and the air compressor generally uses unidirectional compression, that is, on one side of the body, the air is continuously compressed by piston movement. Although this compression method can achieve the compression effect on the air, the amount of gas that can be compressed at one time is small, resulting in the need for the compressor to continuously perform high-intensity compression operations, which can easily cause damage to the compressor and generate unnecessary economic losses. In order to solve this problem, an air compression mechanism 5 is provided in the present solution, and the active unit in the air compression mechanism 5 drives the first sealing plug 51 and the second sealing plug 52 in the compression unit to be synchronously and reversely linked, thereby forming a bidirectional compression structure in the air compression cylinder 2. The bidirectional compression structure replaces the traditional unidirectional compression structure, thereby greatly improving the compression efficiency of the air. It is simple, efficient and practical.
[0026] Specifically, in this embodiment, the scheme mainly includes a base 1, an air compression cylinder 2, an air inlet pipe 3, an air outlet pipe 4 and an air compression mechanism 5. When in use, the crankshaft 56 in the air compression mechanism 5 is rotated, thereby driving the first driven rod 57 and the second driven rod 58 to be linked, and synchronously driving the first linkage rod 53 and the second linkage rod 54 to be linked, so that the first sealing plug 51 and the second sealing plug 52 can reciprocate up and down and move in the opposite direction in the air compression cylinder 2, thereby compressing the air in the air compression cylinder 2 and discharging it through the air outlet pipe 4, and the filter can be blown to remove dust.
[0027] In a further preferred embodiment of the present invention, Figures 1-4 As shown, the active unit includes a support base 55, a crankshaft 56, a first driven rod 57 and a second driven rod 58. The support base 55 is fixed on the base 1, and the center of the crankshaft 56 is rotatably connected in the support base 55. The first driven rod 57 is rotatably connected between one side of the crankshaft 56 and the first connecting rod 53, and the second driven rod 58 is rotatably connected between the other side of the crankshaft 56 and the second connecting rod 54.
[0028] In this embodiment, the rotation of the crankshaft 56 drives the first driven rod 57 and the second driven rod 58 to move in a synchronous manner, thereby driving the first linkage rod 53 and the second linkage rod 54 to move in a synchronous and reverse manner.
[0029] In a further preferred embodiment of the present invention, Figures 1-4 As shown, a servo motor 59 is fixed on the side wall of the support seat 55 , and the output shaft of the servo motor 59 is coaxially connected to the center of the crankshaft 56 .
[0030] In this embodiment, the crankshaft 56 is driven to rotate by the servo motor 59 .

[0032] In this embodiment, the adjacent two sets of crankshafts 56 can be synchronously linked through the gears 510.
[0033] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, limiting blocks 6 are arranged inside both the intake pipe 3 and the exhaust pipe 4, and a baffle 7 is rotatably connected to the limiting block 6 through a rotating rod, a torsion spring is arranged on the rotating rod, the baffle 7 in the intake pipe 3 is arranged on one side close to the inside of the air compression cylinder 2, and the baffle 7 in the exhaust pipe 4 is arranged on one side close to the outside of the air compression cylinder 2.
[0034] In this embodiment, a one-way valve structure is formed by the baffle 7, so that when the air compression mechanism 5 compresses, the intake pipe 3 can be closed through the baffle 7 and the exhaust pipe 4 is opened, and the baffle 7 can move in the reverse direction when inhaling.
[0035] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, air guide pipes 8 are detachably connected to both the intake pipe 3 and the exhaust pipe 4 by threads.
[0036] In this embodiment, the air flow can move in a directional manner through the air guide pipes 8.
