Description

Technical Field

[0001] This utility model relates to an industrial reversing dust collection device, which is applicable to the field of vacuum cleaner manufacturing technology. Background Technology

[0002] Industrial vacuum cleaners are commonly used environmentally friendly cleaning equipment in industry, used to remove dust particles from industrial production environments. They are widely used in various industries such as chemical, textile, and decoration. After a period of use, a large amount of dust particles accumulates on the filter screen of an industrial vacuum cleaner, which can easily affect the filter's airflow performance and thus the overall efficiency of the vacuum cleaner. Therefore, industrial vacuum cleaners require regular cleaning or filter replacement. Currently, most industrial vacuum cleaners require disassembling the device and removing the filter for cleaning or replacement, a very cumbersome, time-consuming, and labor-intensive process that not only affects work efficiency but also wastes manpower and costs. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model proposes an industrial reversing dust collection device.

[0004] The technical solution adopted by this utility model is an industrial reversing dust collection device, including a dust collection bin, a filter assembly disposed within the dust collection bin, a dust collection port and a first suction / blowing port and a second suction / blowing port disposed on the dust collection bin, and a fan unit connected to the first suction / blowing port and the second suction / blowing port. The filter assembly includes a filter element embedded in the dust collection bin and dividing the internal space of the dust collection bin into a dust collection area and a filtration area through its filter surface, and a partition assembly disposed within the filtration area and dividing the filtration area into a first region and a second region. The dust collection port is connected to the dust collection area. The first and second suction / blowing ports are connected to the first and second areas respectively. The industrial reversing dust collector has three working states. When it is in the first working state, air enters through the suction port and air exits through both the first and second suction / blowing ports. When the industrial reversing dust collector is in the second working state, air enters through both the suction port and the first suction / blowing port and air exits through the second suction / blowing port. When the industrial reversing dust collector is in the third working state, air enters through both the suction port and the second suction / blowing port and air exits through the first suction / blowing port. The dust collection bin is divided into a first zone and a second zone by a partition assembly, and the first and second zones are connected by a first suction / blowing port and a second suction / blowing port, respectively. The vacuum cleaner switches between two operating states: in the first operating state, the fan unit simultaneously draws air through both the first and second suction / blowing ports, drawing dust into the dust collection bin and filtering it from both zones; in the second operating state, the fan unit simultaneously draws dust through the second suction / blowing port and back-blown air through the first suction / blowing port, thus improving the suction efficiency. Dust adhering to the filter element in the first area is blown off the filter element surface, with some falling below the suction area. When the vacuuming device is in the third working state, the fan unit draws dust from the first suction / blowing port and blows it back through the second suction / blowing port, blowing off the dust adhering to the filter element in the second area. By repeatedly switching the suction and blowing of the two suction / blowing ports of the vacuuming device, the dust adhering to the filter element can be automatically cleaned in a timely manner, maintaining the filter element in good condition. This eliminates the need for frequent disassembly or replacement of the filter element, reducing workload and operating costs, thus improving work efficiency and reducing labor consumption. Furthermore, the partition assembly separates a single filter element into two working areas, simplifying the internal structure, eliminating the need for two separate filter elements, reducing equipment size, lowering production costs, and improving ease of use.

[0005] Furthermore, the filter element is designed as a frustum shape, wider at the top and narrower at the bottom, with an opening at the top. The filter element engages with the inner wall of the dust collection bin via its upper outer edge. The inner wall of the filter element and the inner wall of the dust collection bin above the filter element together form the filtration zone, while the outer wall of the filter element and the inner wall of the dust collection bin below the filter element together form the suction zone. Specifically, the filtration surface of the filter element is the side of the frustum shape. By designing the filter element as a frustum shape, it is easy to separate the filtration zone and the suction zone within the dust collection bin, simplifying the equipment structure.

[0006] Furthermore, the dust collection bin includes a bin body, a bin lid covering the top of the bin body, a filter element located inside the bin body, and both the first and second suction / blowing ports located on the bin lid, while the dust suction port is located on the bin body. The bin lid facilitates filter element replacement, and placing both the first and second suction / blowing ports on the bin lid improves structural utilization and further simplifies the equipment structure.

[0007] Furthermore, the baffle assembly includes a first baffle fixedly disposed on the inner side of the filter element along its axis, and a second baffle fixedly disposed on the bottom surface of the lid and on the same plane as the first baffle. When the lid is placed on the container body, the upper end of the first baffle and the lower end of the second baffle abut against each other. By splitting the baffle assembly into a first baffle and a second baffle respectively disposed on the filter element and the lid, the convenience of separating the filtration zones is improved, and filter element replacement is facilitated.

[0008] Furthermore, a sealing strip is provided between the first partition and the second partition, which improves the sealing between the first partition and the second partition and ensures that the first area and the second area are independent of each other.

[0009] Furthermore, the dust collection bin also includes a dust collection pipe located at the bottom of the bin body for placing dust bags on it. The outer wall of the dust collection pipe is provided with a locking device for securing the dust bags. Dust blown away from the filter element falls from the dust collection pipe into the dust bags below, facilitating dust collection. Optionally, the locking device is provided with at least four hooks to facilitate attaching the opening of the dust bag to the dust collection pipe and hanging it on the hooks.

[0010] Furthermore, the dust collection bin also includes a baffle plate horizontally installed inside the dust collection pipe, with a dust collection port between the baffle plate and the inner wall of the dust collection pipe for dust to fall. By installing the baffle plate, the vortex formed by the airflow inside the dust collection bin is prevented from affecting the dust bag below the baffle plate, thus preventing the airflow from rolling out the dust that has fallen into the dust bag.

[0011] Furthermore, the vacuuming device also includes a frame, with the dust collection bin and fan unit all fixedly connected to the frame, facilitating the movement of the vacuuming device via the frame and improving ease of use.

[0012] Furthermore, the frame includes a vertically arranged frame body, a tray plate arranged on the lower part of one side of the frame body in a direction perpendicular to the frame body, and a dust collection bin fixed to one side of the frame body and located above the tray plate, making it convenient to place the dust bag on the tray plate.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] The industrial reversing dust collection device of this utility model has a simple structure and is easy to use. A partition assembly divides a single filter element into two working areas. By switching between suction and blowing in each working area, the dust collection device can clean the filter element promptly during operation, maintaining its good condition. This eliminates the need for frequent filter disassembly or replacement, reducing workload and operating costs, thus improving work efficiency and reducing labor consumption. Furthermore, dividing a single filter element into two working areas with the partition assembly simplifies the internal structure, eliminating the need for two separate filter elements, reducing equipment size, lowering production costs, and improving ease of use.

[0022] Reference Appendix Figure 1-2The industrial reversing dust collection device in this embodiment includes a dust collection bin 1, a filter assembly 2 disposed within the dust collection bin 1, a suction port 11 and a first suction / blowing port 12 and a second suction / blowing port 13 opened on the dust collection bin 1, and a fan unit 3 connected to the first suction / blowing port 12 and the second suction / blowing port 13. The filter assembly 2 includes a filter element 21 embedded in the dust collection bin 1 and dividing the internal space of the dust collection bin 1 into a suction area 22 and a filtration area 23 through its filter surface, and a partition assembly 24 disposed within the filtration area 23 and dividing the filtration area 23 into a first region 241 and a second region 242. The suction port 11 and the suction area 22... The first suction / blowing port 12 and the second suction / blowing port 13 are connected to the first area 241 and the second area 242, respectively. The industrial reversing dust collector has three working states. When it is in the first working state, the suction port 11 takes in air, and the first suction / blowing port 12 and the second suction / blowing port 13 both take out air. When the industrial reversing dust collector is in the second working state, both the suction port 11 and the first suction / blowing port 12 take in air, and the second suction / blowing port 13 takes out air. When the industrial reversing dust collector is in the third working state, both the suction port 11 and the second suction / blowing port 13 take in air, and the first suction / blowing port 12 takes out air. The filter area 23 inside the dust collection bin 1 is divided into a first area 241 and a second area 242 by the partition assembly 24. The first area 241 and the second area 242 are connected by the first suction / blowing port 12 and the second suction / blowing port 13, respectively. Then, by switching the working state of the dust collection device, when it is in the first working state, the fan unit 3 simultaneously draws air through the first suction / blowing port 12 and the second suction / blowing port 13, drawing dust from the dust suction port 11 into the dust collection bin 1, and simultaneously filtering it from the first area 241 and the second area 242; when the dust collection device is in the second working state, the fan unit 3 simultaneously draws dust from the second suction / blowing port 13 and through the first suction / blowing port 13. Back-blowing at port 12 causes dust adsorbed on the filter element 21 in the first region 241 to be blown off the surface of the filter element 21, with some falling below the suction area 22. When the dust collection device is in the third working state, the fan unit 3 draws dust from the first suction / blowing port 12 and back-blowing through the second suction / blowing port 13, blowing off the dust adsorbed on the filter element 21 in the second region 242. By repeatedly switching the suction and blowing of the two suction / blowing ports of the dust collection device, the dust adsorbed on the filter element can be automatically cleaned in a timely manner, maintaining the filter element in good condition. There is no need to frequently disassemble or replace the filter element, reducing workload and operating costs, which not only improves work efficiency but also reduces labor consumption. Furthermore, the partition assembly separates a single filter element into two working areas, simplifying the internal structure, eliminating the need for two separate filter elements, reducing equipment size, lowering production costs, and improving ease of use.

Specifically, the filtration surface of the filter element 21 is the side of the frustum shape. By configuring the filter element as a frustum shape, it is easier to divide the dust collection bin 1 into the filtration zone 23 and the suction zone 22, simplifying the equipment structure.

[0024] In a more preferred embodiment, the dust collection bin 1 includes a bin body 14 and a bin cover 15 covering the bin body 14. The filter element 21 is disposed inside the bin body 14. The first suction / blowing port 12 and the second suction / blowing port 13 are both located on the bin cover 15, and the dust suction port 11 is located on the bin body 14. The bin cover 15 facilitates the replacement of the filter element 21, and the placement of the first suction / blowing port 12 and the second suction / blowing port 13 on the bin cover 15 improves the utilization rate of the structure and further simplifies the equipment structure.

When the lid 15 is placed on the body 14, the upper end of the first partition 243 abuts against the lower end of the second partition 244. By dividing the partition assembly 24 into the first partition 243 and the second partition 244 respectively disposed on the filter element 21 and the lid 15, the convenience of separating the filtration zone 23 is improved, and the filter element is easier to replace.

[0026] In a more preferred embodiment, a sealing strip 245 is provided between the first partition 243 and the second partition 244, which improves the sealing between the first partition 243 and the second partition 244 and ensures that the first region 241 and the second region 242 are independent of each other.

[0027] In a more preferred embodiment, the dust collection bin 1 further includes a dust collection pipe 16 disposed below the bin body 14 for placing a dust bag on it.

By providing the baffle plate 17, the vortex formed by the airflow within the dust collection bin 1 is prevented from affecting the dust bag below the baffle plate 17, thus preventing the airflow from rolling out the dust that has fallen into the dust bag.

[0029] In a more preferred embodiment, the vacuuming device also includes a frame 4, with the dust collection bin 1 and the fan unit 3 all fixedly connected to the frame 4, facilitating the movement of the vacuuming device via the frame 4 and improving ease of use.
