Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and more specifically, to a dual-link cross-back-blowing dust removal structure for industrial vacuum cleaners. Background Technology

[0002] Industrial vacuum cleaners, as indispensable specialized dust removal equipment in industrial production scenarios, are widely used in various industries such as machining, chemical, metallurgy, building materials, new energy, and food processing. Their core function is to efficiently collect and filter solid or liquid waste such as dust, iron filings, oil stains, and sand generated during production. Compared to household vacuum cleaners, industrial vacuum cleaners possess key advantages such as high negative pressure, strong suction, high filtration accuracy, and durability. They not only ensure the cleanliness of the production environment but also enable the recycling of usable materials such as metal scraps. Furthermore, they effectively reduce the impact of dust on the precision and lifespan of production equipment, as well as its harm to the respiratory health of operators. Therefore, they are crucial equipment for ensuring safe, environmentally friendly, and efficient operation in industrial production processes.

[0003] The filtration system (filter cartridge / filter bag) is the core component of an industrial vacuum cleaner for dust interception, and its filtration performance directly determines the vacuum cleaner's dust removal effect and operational stability. However, in continuous industrial production scenarios, dust will continuously adhere to the surface of the filter material in the filtration system, gradually forming a dense "dust layer".

[0004] In existing technologies, industrial vacuum cleaners typically employ single back-blowing, vibration cleaning, or manual cleaning methods for dust removal. Single back-blowing cleaning has limitations in its cleaning range and the potential for creating blind spots, making it impossible to completely remove the dust layer. Vibration cleaning, on the other hand, can damage the filter material due to excessive vibration intensity, and its cleaning effect is greatly affected by vibration frequency and amplitude, resulting in insufficient stability. Manual cleaning is not only labor-intensive and inefficient but also requires interrupting production operations, severely impacting production continuity. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dual-link cross-back-blowing dust cleaning structure for industrial vacuum cleaners, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a dual-link cross-back-blowing dust removal structure for an industrial vacuum cleaner, including a reinforcing frame installed inside the industrial vacuum cleaner, and two sets of dust removal components are provided on the reinforcing frame; The dust removal assembly includes a flow guide box disposed at the top of the inner cavity of the reinforcing frame, a vertical pipe disposed at the bottom of the flow guide box, a connecting ring disposed at the bottom of the vertical pipe, and a hollow cross plate rotatably connected to the connecting ring. The bottom of the hollow cross plate is provided with a dust removal cross rod, and several spray holes for diverting the flow are opened through the dust removal cross rod.

[0007] Optionally, in a possible implementation, the hollow cross plate is hollow and connected to the vertical pipe and the guide box for airflow to be transported to the guide box and then to the hollow cross plate via the vertical pipe. The cross-sectional shape of the hollow cross plate and the cleaning cross rod is cross-shaped, and the cleaning cross rod is detachably connected to the hollow cross plate by bolts. An air inlet valve for guiding the flow is provided on the outside of the guide box, and the air inlet valve is threadedly connected to the guide box. Optionally, in a possible implementation, a groove is provided through the top of the reinforcing frame, and a slider is slidably connected in the groove. A motor is provided on the top of the slider, and the output end of the motor passes through the slider, the guide box, the vertical pipe, the connecting ring, and the hollow cross plate in sequence and extends to the dust removal cross bar. The two dust removal structures are arranged opposite to each other, and a spring is provided between the sliders to which the two dust removal components belong. The slider is installed on the top of the guide box by bolts, and the guide box is adjusted when the slider is finely adjusted by the elasticity of the spring itself.

[0008] The technical effects and advantages of this utility model are as follows: By employing two sets of opposing dust removal components, dust removal is achieved through a double-linked cross-backflushing design. Both sets of dust removal components feature cross-shaped cleaning arms that rotate synchronously under motor drive. During rotation, the cross arms form an intersecting coverage area, enabling comprehensive, thorough backflushing cleaning of the entire filter element surface. This completely removes the dust layer adhering to the filter material surface, effectively solving the problems of incomplete cleaning and numerous dead angles inherent in traditional dust removal methods. The cleaning method primarily utilizes high-pressure airflow cross-backflushing, combined with the slow rotation of the cleaning crossbar, ensuring effective dust removal while preventing impact damage to the filter material. Simultaneously, the coordinated design of the spring, slider, and groove allows for self-adjusting of the cleaning assembly's position, ensuring a consistent distance between the cleaning crossbar and the filter material, preventing damage caused by excessive localized pressure. Furthermore, the efficient cleaning reduces dust clogging of the filter material pores, slowing down the hardening and aging process, extending the lifespan of the filter element or filter bag, and significantly reducing the frequency of filter material replacement and equipment maintenance costs.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Example 1 This embodiment discloses a dual-link cross-back-blowing dust removal structure for an industrial vacuum cleaner, which aims to solve the technical problem that existing industrial vacuum cleaner filtration systems are prone to forming dust layers during continuous operation, leading to increased suction resistance, decreased suction power, increased energy consumption, reduced filtration accuracy, and even motor burnout.

[0018] Specifically, the dual-link cross-back-blowing dust removal structure of the industrial vacuum cleaner includes a reinforcing frame 1 installed inside the industrial vacuum cleaner. The reinforcing frame 1 is a rectangular frame structure used to provide a mounting support base for the entire dust removal structure. A sliding groove 9 is provided through the top of the reinforcing frame 1. The sliding groove 9 extends along the length of the reinforcing frame 1, and a slider 10 is slidably connected in the sliding groove 9 to ensure that the slider 10 can slide smoothly without excessive shaking.

[0019] Two sets of oppositely arranged cleaning components are provided on the reinforcing frame 1. The two sets of cleaning components are symmetrically distributed with the center line of the reinforcing frame 1 as the axis of symmetry. A spring 12 is fixedly connected between the sliders 10 to which the two cleaning components belong. The natural length of the spring 12 is adapted to the initial distance between the two slides 9. When the slider 10 is displaced, the spring 12 can be reset through its own elastic deformation, thereby driving the cleaning components to make fine adjustments to their positions.

[0020] The dust removal assembly includes a flow guide box 2 fixedly mounted at the bottom of the slider 10. The slider 10 is bolted to the top of the flow guide box 2. When the slider 10 is slightly adjusted in position by the elasticity of the spring 12, the flow guide box 2 can be adjusted horizontally in sync. The flow guide box 2 is a hollow cuboid structure. An air inlet valve 8 for guiding airflow is threaded onto its outer wall. The input end of the air inlet valve 8 is connected to the high-pressure airflow source of the industrial vacuum cleaner. By controlling the opening and closing of the air inlet valve 8, the airflow pressure and flow rate entering the flow guide box 2 can be adjusted.

[0021] A vertical tube 3 is integrally formed at the bottom center of the flow guide box 2. The vertical tube 3 is a cylindrical hollow structure, and its axis coincides with the center line of the flow guide box 2. A connecting ring 4 is welded to the bottom of the vertical tube 3. The connecting ring 4 is an annular structure, and its inner diameter is the same as that of the vertical tube 3. The bottom of the connecting ring 4 is rotatably connected to a hollow cross plate 5 via a bearing. The bearing is a sealed bearing to prevent dust from entering and affecting the rotation performance. The hollow cross plate 5 is designed with an internal hollow structure. A sealing gasket is set at the connection between its top and the connecting ring 4 to ensure airflow is transmitted in a sealed manner. The hollow cross plate 5 is connected to the vertical tube 3 and the flow guide box 2, and is used to stably transport the airflow in the flow guide box 2 to the hollow cross plate 5 through the vertical tube 3.

[0022] The bottom of the hollow cross plate 5 is detachably connected to the dust removal cross rod 6 via bolts. Both the hollow cross plate 5 and the dust removal cross rod 6 have a cross-shaped cross section to ensure that the dust removal range can cover the entire surface of the filter element. Several nozzles 7 for diverting the flow are opened through the dust removal cross rod 6. The nozzles 7 are evenly distributed along the length of the dust removal cross rod 6, so that the back-blowing airflow can act on the surface of the filter element in an inclined direction, improving the dust removal effect.

[0023] Example 2 Based on Embodiment 1, in this embodiment, a motor 11 is fixedly mounted on the top of the slider 10 via a motor mounting base. The motor 11 is a servo motor, and its output end is connected to the transmission shaft via a coupling. The transmission shaft passes through the slider 10, the guide box 2, the vertical tube 3, the connecting ring 4, and the hollow cross plate 5 in sequence and extends to the center position of the cleaning cross rod 6. The transmission shaft and the cleaning cross rod 6 are fixedly connected by a flat key to ensure that the motor 11 can drive the cleaning cross rod 6 to rotate synchronously.

[0024] The specific working principle is as follows: When the dust adhering to the surface of the filter element / filter bag of the industrial vacuum cleaner's filtration system reaches the set threshold, the dust removal program is started. First, the air inlet valves 8 of the two sets of dust removal components are opened synchronously. The high-pressure airflow enters the guide box 2 from the air inlet valve 8, and after being evenly distributed by the guide box 2, it is transported to the hollow cross plate 5 through the vertical pipe 3. The hollow cross plate 5 guides the airflow into the cleaning cross bar 6, and sprays it onto the surface of the filter element / filter bag through several nozzles 7 on the cleaning cross bar 6, forming a back-blowing airflow. The impact force of the airflow is used to peel off the dust layer attached to the surface of the filter element / filter bag. At the same time, the motors 11 corresponding to the two sets of dust removal components are started. The motors 11 drive the transmission shaft to rotate the dust removal cross rod 6, so that the back-blowing airflow ejected from the nozzle 7 can act on the surface of the filter element / filter bag in a rotating manner, thus expanding the dust removal coverage area. Since the two sets of dust removal structures are set opposite to each other, and the dust removal cross rods 6 are all cross-shaped, during the rotation, the cross arms of the two sets of dust removal cross rods 6 form an intersecting coverage area, achieving a cross-blowing effect and avoiding dust removal dead corners. During the dust removal process, the spring 12 applies a preload force to the slider 10 through its own elasticity. When the impact force generated by the backflow causes the dust removal assembly to shift slightly, the spring 12 can drive the slider 10 to slide slightly in the groove 9, thereby achieving adaptive adjustment of the position of the dust removal assembly and ensuring that the distance between the dust removal crossbar 6 and the filter element / filter bag remains consistent, thus ensuring a uniform and stable dust removal effect. The stripped dust falls into the dust collection device of the industrial vacuum cleaner under the action of gravity, completing the dust removal operation. After the dust removal is completed, the air inlet valve 8 and the motor 11 are closed, and the dust removal component is reset to the initial position under the action of the spring 12, waiting for the next dust removal command.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
