It usually has strong suction and a large-capacity dust box, and can cope with large-scale, high-intensity cleaning tasks. The working principle of an industrial vacuum cleaner is to use a motor to drive the fan to rotate at high speed to generate negative pressure, thereby sucking pollutants into the dust box; its application scenarios are very wide, such as factory workshops, construction sites, warehouses, textile mills, etc. In factory workshops, it can clean up metal chips and dust generated by machinery and equipment; at construction sites, it can remove construction waste and dust; in textile mills, it can collect fiber waste, etc.

The frequency of the pulse controller installed on the top end cover of the air storage tank is adjusted to control the number of jets from the spiral nozzle per unit time of the electromagnetic pulse valve to back-blow the filter cartridge, which is convenient for continuous packaging of dust and saves the operating time of replacing the dust bag each time, and solves the problems of incomplete gas-solid separation, low structural strength, poor stability, troublesome dust recovery, low filtration accuracy and poor efficiency of the filter, and a shortened service life of the filter, which requires frequent replacement.

[0004] In the process of using industrial vacuum cleaners to clean industrial environments, most of the existing industrial vacuum cleaners on the market have continuous bags installed at their material inlet through a fastening structure. When the staff fixes the continuous bag, they repeatedly operate the fastening structure to tighten the fastening structure and bind the continuous bag to the unloading part of the equipment. Since the disassembly and assembly operation of the fastening structure is cumbersome and time-consuming, the staff will be disturbed by the fastening structure when disassembling and assembling the continuous bag.

[0024] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a pulse backflush type industrial vacuum cleaner, including a mobile base 1, a body 2 and an auxiliary component 7. The body 2 is installed on the upper surface of the mobile base 1. A corrugated expansion pipe 3 is installed on the upper surface of the body 2. A column 4 is installed on the upper surface of the mobile base 1. A dust collection bucket 5 is installed on the side surface of the column 4. A dust suction interface 6 is installed on the arc surface of the dust collection bucket 5. The auxiliary component 7 is arranged on the surface of the column 4.

[0025] In this implementation: The auxiliary component 7 includes a clamping unit 71. The clamping unit 71 includes a lifting cylinder 711. The lifting cylinder 711 is fixedly connected to the side surface of the column 4. The driving end of the lifting cylinder 711 is bolted with a connecting ring 712. The upper surface of the connecting ring 712 is fixedly connected with a load-bearing plate 713. The side surface of the load-bearing plate 713 is fixedly connected with a support plate 714. The side surface of the support plate 714 is fixedly connected with a limiting collar 715. The inner wall of the limiting collar 715 is fixedly connected with a damping rubber sleeve 716;

[0026] The auxiliary component 7 further includes a constraint unit 72. The constraint unit 72 includes a fixed column 721. The fixed column 721 is fixedly connected to the surface of the support plate 714. The arc surface of the fixed column 721 is bolted with a U-shaped block 722. The upper surface of the U-shaped block 722 is fixedly connected with a mounting plate 723. The upper surface of the mounting plate 723 is fixedly connected with a positioning frame 724. The inner wall of the positioning frame 724 is fixedly connected with a reverse curved bar 725.

[0027] Specifically, the number of the lifting cylinders 711 is two. The two lifting cylinders 711 are symmetrically arranged about the dust collection bucket 5. Through the cooperation of the lifting cylinder 711 and the connecting ring 712, the load-bearing plate 713 can be lifted upward when the lifting cylinder 711 works.

[0028] Specifically, the number of the load-bearing plates 713 is two. The two load-bearing plates 713 are symmetrically arranged about the mobile base 1. The load-bearing plate 713 abuts against the surface of the column 4.

[0029] In this embodiment: When the jacking cylinder 711 performs a jacking operation, the bearing plate 713 can push the support plate 714 upward to move.

[0030] Specifically, the support plate 714 is slidably connected to the surface of the column 4. The bearing plate 713 and the limit collar 715 can be connected through the support plate 714 to achieve the linkage effect between the two.

[0031] In this embodiment: The inner diameter of the damping rubber sleeve 716 is larger than the lower end diameter of the dust collection barrel 5.

[0032] In this embodiment: By setting the inner diameter of the damping rubber sleeve 716 to be larger than the lower end of the dust collection barrel 5, the damping sleeve can be sleeved on the lower end of the dust collection barrel 5 and cooperate with the lower end of the dust collection barrel 5 to limit the position of the continuous sleeve bag.

[0033] Specifically, the number of the fixing columns 721 is two. The two fixing columns 721 are symmetrically arranged left and right with respect to the limit collar 715. The number of the mounting plates 723 matches the number of the fixing columns 721, and the number of the positioning frames 724 matches the number of the fixing columns 721. The position of the U-shaped block 722 can be supported by the fixing columns 721 in cooperation with the support plate 714 to ensure that the position of the U-shaped block 722 is on both sides of the limit collar 715.

[0034] Specifically, the number of the anti-curved bars 725 is two. The two anti-curved bars 725 are symmetrically arranged left and right with respect to the limit collar 715. Both ends of the anti-curved bar 725 are hemispherical.

[0035] In this embodiment: When the staff installs the continuous sleeve bag, the position of the continuous sleeve bag can be preliminarily constrained by the anti-curved bar 725 to ensure that the continuous sleeve bag is always inside the limit collar 715.

[0036] Working principle: when working, the fuselage 2 is powered on and works in conjunction with the bellows telescopic tube 3 to generate suction. The generated suction cooperates with the dust collecting bucket 5 and the suction nozzle installed on the dust collecting structure to absorb the dust in the working environment. The sucked dust enters the dust collecting bucket 5 and then falls into the continuous bag installed under the dust collecting bucket 5; when installing the continuous bag, the continuous bag is passed through the limiting ring 715 to open the opening of the continuous bag, and the two sides of the opening are sleeved on the reverse bending rod 725. The reverse bending rod 725 props up the opening of the continuous bag and constrains the position of the continuous bag in the limiting ring 715. Then the lifting cylinder 711 is turned on and works in conjunction with the connecting ring 712 to push the load-bearing plate 713 upwards. The load-bearing plate 713 lifts the support plate 714. The support plate 714 pushes the limiting ring 715 under the action of the load-bearing plate 713. At the same time, the support plate 714 cooperates with the fixing column 721 to push the U-shaped block 722. The U-shaped block 722 pushes the mounting plate 723. The mounting plate 723 pushes the positioning frame 724 and the reverse bending rod 725 to move. The continuous bag is displaced under the drive of the reverse bending rod 725 and is sleeved to the lower end of the dust collecting bucket 5. At the same time, the limiting ring 715 pushes the damping rubber sleeve 716 to the lower end of the dust collecting bucket 5, and cooperates with the dust collecting bucket 5 to clamp and limit the continuous bag. By setting the auxiliary component 7, the disassembly and assembly operation of the continuous bag is faster, thereby reducing the cumbersome operation of the fastening structure of the continuous bag, resulting in the slow disassembly and assembly efficiency of the continuous bag, and further improving the installation and disassembly efficiency of the vacuum cleaner bag.
