Description

Technical Field

[0001] This utility model relates to the field of purification equipment technology, specifically a dynamic negative pressure adaptive oil mist-dust composite capture and purification device. Background Technology

[0002] In modern processing industries, oil mist and dust are two common processing wastes. The oil mist-dust composite capture and purification device is a highly efficient purification device for pollutants that coexist in industrial environments, such as oil mist (e.g., cutting fluid mist, lubricating oil mist) and dust (e.g., metal dust, wood chips, plastic particles, etc.).

[0003] Its core objective is to achieve the synergistic treatment of multiple pollutants to meet environmental emission standards, while also taking into account energy conservation and maintenance costs. This type of equipment usually uses negative pressure as the driving force for guiding oil mist and dust. Under normal operating conditions, this equipment is often at a fixed power. However, if the amount of powder and oil mist processed increases during the processing, the filter side may not be able to adjust in time, resulting in poor filtration effect or increasing the burden on single-stage filtration equipment. In view of this, in-depth research was conducted on the above problems, which led to the creation of this case. Utility Model Content

[0013] Beneficial effects

[0014] This invention provides a dynamic negative pressure adaptive oil mist-dust composite capture and purification device.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides an implementation scheme: In modern integrated oil mist and dust purification equipment, negative pressure is usually used as the driving force for guiding oil mist and dust. Such equipment is usually at a fixed power under normal operating conditions. However, if the amount of powder and oil mist processed increases during the processing, the filter side may not be able to adjust in time, resulting in poor filtration effect or increasing the burden on single-stage filtration equipment.

[0021] To address the aforementioned issues, this application discloses a dynamic negative pressure adaptive oil mist-dust composite capture and purification device, comprising a capture hood 1, one end of which is connected to an air duct 2. The capture hood 1 extends into the working position to expand the contact area. A comprehensive filter 3 is installed at the end of the air duct 2, and a negative pressure air guide fan 4 is connected to the comprehensive filter 3. The negative pressure air guide fan 4 generates negative pressure to draw air containing external suspended oil mist from one side of the capture hood 1 into the comprehensive filter 3 through the air duct 2. The comprehensive filter 3 performs filtration. Furthermore, an oil mist sensor 5 and a dust sensor 6 are installed on the capture hood 1. The operating frequency of the negative pressure fan is controlled by real-time sensing of the oil mist and dust concentration, thereby changing the ventilation volume per unit time.

[0022] According to the instruction manual Figure 1-3 It can be seen that the above-mentioned integrated filter 3 includes a filter housing 31, the filter housing 31 is installed on the ventilation pipe 2, the filter housing 31 is connected to the capture air hood 1, the filter housing 31 has a number of adjustment ports 32 arranged in a linear array, the number of adjustment ports 32 passes through the top surface of the filter housing 31, the number of adjustment ports 32 are equipped with a number of filter screens 33, and an oil-absorbing cotton layer 34 is provided on one side of the filter screen 33.

[0023] According to the instruction manual Figure 1-3 It can be seen that the above-mentioned integrated filter 3 also includes a connecting seat 35. The top of the filter screen 33 extends integrally from the connecting seat 35. A filter retraction regulator 36 is provided on the filter housing 31. Several traction rods 362 are provided on the filter retraction regulator 36. Any traction rod 362 is connected to the connecting seat 35. The filter retraction regulator 36 adjusts the lifting and lowering of the traction rod 362.

[0024] In the specific implementation process, the filter shell 31 serves as the main support structure of the integrated filter 3. Air containing oil mist and dust enters the filter shell 31. Several adjustment ports 32 on the filter shell 31 serve as installation spaces for the filter screen 33 and the oil-absorbing cotton layer 34. The filter screen 33 filters the dust, while the oil-absorbing cotton layer 34 absorbs the oil mist. The integrated filter 3 is equipped with a filter retraction regulator 36, which can adjust which filter screens 33 and oil-absorbing cotton layers 34 are working according to the workload. If the power of the negative pressure fan is increased, it indicates a large processing volume, so more oil-absorbing cotton layers 34 and filter screens 33 will be inserted. If the processing volume is small, clean filter screens 33 and oil-absorbing cotton layers 34 will be selected first, automatically and flexibly adapting to the purification workload of oil mist and dust.

[0025] As a preferred option, the capture air shroud 1 is further designed as a partially conical shell.

[0026] As a preferred option, furthermore, several adjustment ports 32 are rectangular plates, the width of the filter screen 33 is the same as the width of the adjustment port 32, and the filter screen 33 and the oil-absorbing cotton layer 34 can completely seal the adjustment port 32.

[0027] As a preferred option, the traction rod 362 and the connecting seat 35 are connected by bolts, which is simple in structure, easy to operate, and convenient for replacement and cleaning.

[0028] As a preferred option, further according to the appendix to the instruction manual... Figure 1-3 It can be seen that the above-mentioned filter retraction regulator 36 includes a fixed housing 361, which is installed on the filter housing 31. A plurality of traction rods 362 are provided on the fixed housing 361, and the top ends of the traction rods 362 are connected to each other. A rotating seat 363 is provided on the fixed housing 361, which is driven to rotate by a rotary motor 364. An adjusting nut 365 is provided on the rotating seat 363, and the adjusting nut 365 is threadedly engaged with the traction rods 362.

[0029] In the specific implementation process, the fixed housing 361 serves as the installation base for the filter retraction regulator 36. The rotary motor 364 on the fixed housing 361 drives the rotating seat 363 to rotate. The rotating seat 363 then drives the adjusting nut 365 to rotate, so that the adjusting nut 365 engages with the traction rod 362. Since the bottom end of the traction rod 362 is fixedly connected to the connecting seat 35, the traction rod 362 can move up and down along the adjusting nut 365, thereby driving the filter screen 33 and the oil-absorbing cotton layer 34 to move up and down. The controller automatically controls one or more rotary motors 364 to work according to the workload of the negative pressure fan, controlling the filter screen 33 and the oil-absorbing cotton layer 34 to be inserted into the filter housing 31.

[0030] As a preferred option, the fixed housing 361 is a rectangular hollow housing with a rotating groove, and the rotating seat 363 is movably mounted on the rotating groove.

[0031] In summary, this dynamic negative pressure adaptive oil mist-dust composite capture and purification device achieves adaptive airflow adjustment by linking an oil mist / dust concentration sensor with a negative pressure fan, thus reducing energy consumption. The modular filter retraction regulator 36 can dynamically add or remove filter screens 33 and oil-absorbing cotton layers 34, expanding the filtration area when the processing volume increases suddenly, and steadily improving purification efficiency. The traction rod 362-screw structure reduces the time required for filter screen replacement and lowers maintenance costs. The multi-stage adjustable oil-absorbing cotton layers 34 improve the oil mist interception rate and reduce overall operating costs, making it suitable for continuous purification needs in highly volatile industrial scenarios.
