Description

Technical Field

[0001] This utility model relates to the field of smoke and dust purifiers, and in particular to a smoke and dust purifier. Background Technology

[0002] Laser cutting technology is widely used in the fields of materials such as metals, plastics, and textiles, and has the advantages of fast, clean, and precise cutting. In the field of laser cutting processing, when a high-energy laser beam interacts with materials such as metals and acrylics, the materials will generate a large amount of complex dust due to reactions such as pyrolysis and oxidation. This dust contains solid particles with a particle size range of 0.1μm-100μm, as well as harmful gaseous pollutants such as volatile organic compounds and nitrogen oxides. If this untreated dust is directly emitted, the particulate matter emission concentration will exceed the prescribed limit. Therefore, dust purifiers are key equipment for controlling air pollution and ensuring the safety of the working environment.

[0003] Existing technology discloses an acrylic sheet processing waste recycling device, such as CN218196323U, which includes a workbench and a collection box. Support plates are bolted to both sides of the top of the workbench, and a fixing plate is bolted to the top of the support plates. A dust removal mechanism is bolted to the top of the fixing plate. The collection box is located in front of the workbench. Through the cooperation of a fan, filter box, first filter screen, air inlet hood, water tank, water pump, and connecting plate, dust is drawn into the filter box for dust removal, improving dust removal efficiency and preventing dust from harming the human body. However, this acrylic sheet processing waste recycling device has the following drawbacks: for example, dust removal is achieved through a single filtration structure, resulting in weak ability to classify and treat pollutants of different particle sizes, poor dust removal effect, and some smoke and dust are still emitted into the atmosphere, causing a certain degree of pollution.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a smoke and dust purifier. Through the structural design and cooperation of a primary filtration mechanism and a secondary filtration mechanism, the primary and secondary filtration mechanisms are arranged sequentially from bottom to top within the purification space. This ensures that smoke and dust are initially filtered by the primary filtration mechanism before entering the filter plate of the secondary filtration mechanism, avoiding direct impact of large particles on the filter material. Then, the fine particles contained in the gas are filtered through the filter plate of the secondary filtration mechanism, thereby improving purification efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dust purifier includes a purifier body, a primary filtration mechanism, a secondary filtration mechanism, and a dust collection plate. The purifier body is provided with a purification space, an air intake, and an air outlet.

[0008] The primary and secondary filtration mechanisms are arranged sequentially from bottom to top within the purification space to divide the purification space into a primary purification chamber and a secondary purification chamber; the air intake is connected to the primary purification chamber, and the air outlet is connected to the secondary purification chamber.

[0009] The primary filtration mechanism includes at least a dust suction channel and a filter connected to the dust suction channel for preliminary purification of exhaust gas by filtering out particles; the dust suction channel is connected to the air intake; the dust collection plate is removable and located at the lower end of the primary purification chamber.

[0010] The secondary filtration mechanism includes a filter plate and a pulse mechanism. The filter plate is located above the filter. The pulse mechanism includes an air storage tank, several electromagnetic pulse valves, and several blow pipes. The output end of the air storage tank is connected to the input end of several electromagnetic pulse valves. The output end of several electromagnetic pulse valves is connected to the input end of several blow pipes. Several nozzles are provided on the blow pipes, and the nozzles are arranged above the filter plate.

[0011] As a preferred embodiment, the pulse mechanism further includes a mounting plate located above the filter plate. The mounting plate has a plurality of air holes spaced apart, and each of the air holes is provided with a bracket. A plurality of jet pipes are provided on the brackets, and a plurality of nozzles are provided corresponding to the air holes.

[0012] As a preferred embodiment, a first mounting component and a second mounting component are respectively fixed in the secondary purification chamber, and the front and rear ends of the filter plate are respectively mounted and positioned on the first mounting component and the second mounting component.

[0013] As a preferred embodiment, the purifier body is equipped with a controller, which is electrically connected to several electromagnetic pulse valves.

[0014] As a preferred embodiment, the primary filtration mechanism further includes a dust collection box, which has a purification chamber with an opening at the bottom. A partition is provided inside the purification chamber, dividing the purification chamber into a first purification chamber, an air duct, and a second purification chamber. A plurality of filters are spaced apart in the first and second purification chambers. A plurality of air inlets connected to the dust collection duct are spaced apart on the partition.

[0015] As a preferred embodiment, the purifier body includes a main body and a cabinet door, wherein the cabinet door is closable and can be opened and closed on the main body.

[0016] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly relies on the structural design and coordination of a primary filtration mechanism and a secondary filtration mechanism. The primary and secondary filtration mechanisms are arranged sequentially from bottom to top within the purification space to divide the purification space into a primary purification chamber and a secondary purification chamber. The air intake is connected to the primary purification chamber, and the air outlet is connected to the secondary purification chamber. In this way, it is ensured that the smoke and dust are initially filtered by the primary filtration mechanism before entering the filter plate of the secondary filtration mechanism, avoiding large particles from directly impacting the filter material. Then, the fine particles contained in the gas are filtered through the filter plate of the secondary filtration mechanism to improve the purification efficiency.

[0017] Secondly, the design of the pulse mechanism is as follows: the air storage tank supplies air to the blow pipe through the electromagnetic pulse valve, and the nozzle is set above the filter plate so that the blow airflow shakes the small dust particles attached to the outer surface of the filter plate into the collection box to achieve the dust removal effect.

[0040] A dust purifier includes a purifier body 10, a primary filtration mechanism 20, a secondary filtration mechanism 30, and a dust collection plate 40.

[0041] The purifier body 10 is provided with a purification space 11, an air intake 12, and an air outlet 13. Preferably, the purifier body 10 is provided with a controller 14, which is electrically connected to several electromagnetic pulse valves. The controller 14 (such as a PLC, microcontroller, or dedicated pulse controller) has a built-in timing module, which can be programmed to set the blowing cycle (the interval between two blowing cycles, such as 10-60 minutes) and the blowing duration (the duration of a single blowing cycle, such as 0.1-0.3 seconds). It can be designed according to actual needs, for example, setting to trigger a blowing cycle every 30 minutes. Each electromagnetic pulse valve opens sequentially for 0.2 seconds, releasing compressed air to the corresponding blowing pipe, forming a pulse airflow that impacts the surface of the filter plate 31 to remove accumulated dust. The controller 14 drives the electromagnetic pulse valves through an electrical signal (such as a DC24V pulse signal). The valve core opens and closes rapidly under the action of electromagnetic force, instantly injecting the compressed air in the air storage tank into the blowing pipe, forming a high-speed airflow through the nozzle.

[0042] Preferably, the purifier body 10 includes a main body and a cabinet door. The cabinet door is openable and closable on the main body, so that when it is necessary to clean the particles or dust on the dust collection plate 40, the dust collection plate 40 can be taken out by opening the cabinet door for cleaning the dust or particles.

[0043] The primary filtration mechanism 20 and the secondary filtration mechanism 30 are arranged sequentially from bottom to top in the purification space 11 to divide the purification space 11 into a primary purification chamber 111 and a secondary purification chamber 112; the air intake 12 is connected to the primary purification chamber 111, and the air outlet 13 is connected to the secondary purification chamber 112.

[0044] The primary filtration mechanism 20 includes at least a dust suction channel 21 and a filter 22 connected to the dust suction channel 21 for preliminary purification of exhaust gas by filtering particles. The dust suction channel 21 is connected to the air intake 12. The dust collection plate 40 is removable and located at the lower end of the primary purification chamber 111.

[0045] The primary filtration mechanism 20 also includes a dust collection box 23, which has a purification chamber 25 with an opening at the lower end. A partition 24 is provided inside the purification chamber 25, which divides the purification chamber 25 into a first purification chamber 251, an air duct, and a second purification chamber 252. A plurality of filters 22 are spaced apart in the first purification chamber 251 and the second purification chamber 252. A plurality of air inlets 241 connected to the dust suction channel 21 are spaced apart on the partition 24. The purification chamber 25 is divided into a first purification chamber 251, an air duct, and a second purification chamber 252 by a partition 24. This allows the smoke and dust to enter the air duct through the air inlet 12 and then be evenly distributed to the first and second purification chambers 252 through multiple air inlets 241 on the partition 24. This ensures that each filter 22 receives a balanced airflow, preventing local overload and filtering larger particles from the smoke and dust to the dust collection plate 40. Furthermore, the spacing between the filters 22 in the first and second purification chambers 252 allows for gradient interception of particles of different sizes. The spacing of the air inlets 241 on the partition 24, combined with the air duct's guiding effect, ensures that the smoke and dust enter the purification chamber at a uniform speed, reducing the impact and wear of the high-speed airflow on the filters 22. At the same time, the design of the air outlet 13 above the filters 22 ensures that the purified gas is quickly discharged, preventing secondary dust re-entrainment.

[0046] The dust collection box 23 includes several side plates and a top plate. The side plates are connected to each other, and the top plate covers the side plates to form a purification chamber 25 with an open end. The side plates are a front side plate, a rear side plate, a left side plate, and a right side plate. The lower ends of the front side plate, the left side plate, and the right side plate are respectively provided with a front placement position, a left placement position, and a right placement position. When the dust collection plate 40 is located at the lower opening of the purification chamber 25, the front, left, and right sides of the dust collection plate 40 abut against the corresponding front placement position, left placement position, and right placement position.

[0047] The dust collection plate 40 is provided with a pull-out part 41 on the side away from the air intake 12. The lower end of the rear side plate is bent upward at least partially to form a clearance opening. When the dust collection plate 40 is located at the lower opening of the purification chamber, the pull-out part 41 is located at the clearance opening.

[0048] The secondary filtration mechanism 30 includes a filter plate 31 and a pulse mechanism 32. The filter plate 31 is located above the filter 22. The pulse mechanism 32 includes an air storage cylinder, a plurality of electromagnetic pulse valves, and a plurality of blow pipes. The output end of the air storage cylinder is connected to the input end of the plurality of electromagnetic pulse valves, and the output end of the plurality of electromagnetic pulse valves is connected to the input end of the plurality of blow pipes. The plurality of blow pipes are provided with a plurality of nozzles, and the plurality of nozzles are arranged above the filter plate 31.

[0049] The pulse mechanism 32 also includes a mounting plate 321, which is located above the filter plate 31. The mounting plate 321 is provided with a plurality of air holes 322 at intervals. A bracket 323 is provided at each of the plurality of air holes 322. A plurality of jet pipes are provided on the brackets 323 and a plurality of nozzles are provided corresponding to the air holes 322. The gas purified by the filter plate 31 is discharged through the plurality of air holes 322 and finally discharged outward through the air outlet 13.

[0050] The first mounting component and the second mounting component are respectively fixed in the secondary purification chamber 112, and the front and rear ends of the filter plate 31 are respectively mounted and positioned on the first mounting component and the second mounting component.

[0051] The key design feature of this invention lies in the structural design and coordination of a primary filtration mechanism and a secondary filtration mechanism. These two mechanisms are sequentially arranged from bottom to top within the purification space, dividing it into a primary purification chamber and a secondary purification chamber. The air intake is connected to the primary purification chamber, and the air outlet is connected to the secondary purification chamber. This ensures that smoke and dust are initially filtered by the primary filtration mechanism before entering the filter plate of the secondary filtration mechanism, preventing large particles from directly impacting the filter material. The secondary filtration mechanism then filters out fine particles in the gas, thereby improving purification efficiency.

[0052] Secondly, the design of the pulse mechanism is as follows: the air storage tank supplies air to the blow pipe through the electromagnetic pulse valve, and the nozzle is set above the filter plate so that the blow airflow shakes the small dust particles attached to the outer surface of the filter plate into the collection box to achieve the dust removal effect.

[0053] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
