Description

Technical Field

[0001] This utility model belongs to the field of dust treatment technology, specifically relating to a dust collection device for a powder packaging machine. Background Technology

[0002] With the rapid development of people's living needs and technological progress, packaging is a general term for containers, materials, and auxiliary materials used in the distribution process to protect products, facilitate transportation, and promote sales, according to certain technical methods. It also refers to the operational activities involving the application of certain technical methods to achieve the aforementioned packaging materials and auxiliary materials. A search revealed that application number "CN202123375054.0" discloses "a dust collection device for a powder packaging machine," which describes how "the rotation of the induced draft fan draws all excess dust from the air or inside the powder packaging machine into the induced draft fan, then transports the dust through the dust collection pipe to the dust collection device body, filters it through the internal filter screen to remove excess impurities, and finally enters the dust collection box through the opening at the bottom of the dust collection device body." The document describes a dust collection device that uses a rotating sliding baffle to slide laterally within the grooves of the upper support disc A and lower support disc B. When the baffle is retracted, the dust collection box can be removed for unified collection. Alternatively, the document describes a method where the rotation of a blower draws excess dust from the air or inside the powder packaging machine. The dust is then transported through a dust collection pipe to the dust collection device body, where it is filtered by an internal filter to remove impurities. Finally, the dust enters the dust collection box through an opening at the bottom of the device body. The document also mentions that rotating the sliding baffle allows it to slide laterally within the grooves of the upper support disc A and lower support disc B, and retracting it allows the dust collection box to be removed for unified collection. However, the document notes that the above comparison document has the following problems in actual use:

[0003] In actual use, larger impurities filtered by the filter cannot be discharged quickly, leading to accumulation, and the lack of explosion-proof function makes the dust prone to explosion.

[0004] Therefore, providing a device that can quickly discharge impurities filtered by a filter and has explosion-proof function is highly practical. Utility Model Content

[0005] The purpose of this invention is to provide a dust collection device for a powder packaging machine, which aims to solve the above-mentioned technical problems.

[0006] This utility model provides a dust collection device for a powder packaging machine, including a protective box, an explosion-proof component, and a filter and discharge component.

[0007] The protective box is made of chromium metal.

[0008] The explosion-proof component includes two connecting frames that are sealed and connected to the top of the protective box. An ion fan is installed inside each of the two connecting frames. A first filter screen is installed at the bottom of each of the two connecting frames. A nitrogen generator is installed at one end of the protective box. A conveying pipe is sealed and connected to the top of the nitrogen generator. An electric valve is sealed and connected to the end of the conveying pipe. A conveying chamber is inserted and connected to one side of the protective box. A spark catcher is sealed and connected to one side of the conveying chamber.

[0009] The filtration and discharge assembly includes several inclined guide rods disposed inside the protective box. Two second filter screens are slidably connected inside the several inclined guide rods. Both sides of the protective box are sealed and connected to conveyor frames. The bottoms of the two conveyor frames are sealed and connected to conveyor boxes. The interiors of the two conveyor boxes are slidably connected to collection boxes. One end of each of the two collection boxes is provided with a first handle.

[0010] In one embodiment of this utility model, a fan unit is sealed and connected to one side of the spark catcher, and a powder packaging machine is sealed and connected to one side of the fan unit.

[0011] In one embodiment of this utility model, a vibration motor is provided on both sides of the protective box, a funnel is provided in the middle of the inner wall of the protective box, and a collection box is movably connected to the bottom of the inner wall of the protective box.

[0012] In one embodiment of this utility model, a protective door is hinged to one end of the protective box, and a second handle is provided at one end of the protective door.

[0013] In one embodiment of this utility model, one side of each of the two conveyor frames corresponds to two second filter screens, and the bottom of the electric valve is sealed and connected to the protective box.

[0014] In one embodiment of this utility model, a door lock is provided inside the second handle, and a controller is provided at the top corner of the protective box.

[0015] In one embodiment of this utility model, the ion fan, nitrogen generator, electric valve, spark catcher, fan unit, powder packaging machine and vibration motor are all electrically connected to the controller, and the controller is electrically connected to an external power supply.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1) The ion fan allows users to easily activate the ion fan, nitrogen generator, electric valve, and spark arrester via the controller when collecting dust. The ion fan, through its built-in high-voltage generator, ionizes the air, generating a large number of positive and negative ions. These ions are then sent into the air by the fan, forming an airflow of positive and negative charges. This neutralizes the static charge on the surface of objects, effectively reducing the accumulation of static electricity between dust and equipment due to friction, thus lowering the risk of explosion. The nitrogen generator facilitates the generation of nitrogen gas, which is then delivered through a delivery pipe and an electric valve into the protective chamber, thereby reducing the oxygen concentration and suppressing the possibility of explosion. The spark arrester intercepts and extinguishes any sparks entering the protective chamber to prevent them from igniting the internal dust, thus achieving the goal of preventing dust explosions.

[0018] 2) The second filter facilitates the feeding of dust generated by the powder packaging machine into the conveying chamber by the fan unit. The dust is then fed into the funnel and falls onto one of the second filter screens. At this point, the operator turns on the vibration motor via the controller, causing it to vibrate and filter the dust through the filter screen. Larger particles that cannot be filtered will flow along the second filter screen to the conveyor frame and be sent to the collection box for collection. The other second filter screen is used in the same way. The filtered dust will flow into the collection box for collection and batch cleaning, thereby achieving the purpose of rapid filtration and discharge. Attached Figure Description

[0026] Example

[0027] Please see Figures 1-4 A dust collection device for a powder packaging machine includes a protective box 100, an explosion-proof component 200, and a filter and discharge component 300.

[0028] Please refer to the details. Figure 1 The protective box 100 is made of chromium metal.

[0029] Please see Figure 1-4 The explosion-proof component 200 includes two connecting frames 210 that are sealed and connected to the top of the protective box 100. An ion fan 220 is installed inside each of the two connecting frames 210. A first filter screen 230 is installed at the bottom of each of the two connecting frames 210. A nitrogen generator 240 is installed at one end of the protective box 100. A conveying pipe 250 is sealed and connected to the top of the nitrogen generator 240. An electric valve 260 is sealed and connected to the end of the conveying pipe 250. A conveying chamber 270 is inserted and connected to one side of the protective box 100. A spark catcher 280 is sealed and connected to one side of the conveying chamber 270.

[0030] In one specific embodiment, the ion fan 220 allows users to easily activate the ion fan 220, nitrogen generator 240, electric valve 260, and spark catcher 280 via a controller when collecting dust. The ion fan 220 ionizes the air through its built-in high-voltage generator, generating a large number of positive and negative ions. These ions are then sent into the air by the fan, forming an airflow of positive and negative charges, thereby neutralizing the static charge on the surface of objects. This effectively reduces the accumulation of static electricity between dust and equipment due to friction, lowering the risk of explosion. The nitrogen generator 240 generates nitrogen, which is then delivered through the delivery pipe 250 and electric valve 260 into the protective box 100 to reduce the oxygen concentration and suppress the possibility of explosion. The spark catcher 280 intercepts and extinguishes any sparks entering the protective box 100 to prevent them from igniting the internal dust, thus achieving the purpose of preventing dust explosions.

[0031] Please see Figure 3 The filter discharge assembly 300 includes several inclined guide rods 310 disposed inside the protective box 100. Two second filter screens 320 are slidably connected inside the several inclined guide rods 310. Both sides of the protective box 100 are sealed and connected to conveyor frames 330. The bottom of the two conveyor frames 330 is sealed and connected to conveyor boxes 340. The inside of the two conveyor boxes 340 is slidably connected to collection boxes 350. One end of each collection box 350 is provided with a first handle 360.

[0032] In one specific embodiment, the second filter 320 facilitates the feeding of dust generated by the powder packaging machine 500 from the fan unit 400 into the conveying chamber 270, and then into the funnel 700. The dust then falls onto one of the second filters 320 through the funnel 700. At this time, the user turns on the vibration motor 600 through the controller, causing the vibration motor 600 to vibrate and filter the dust through the filter. Larger particles that cannot be filtered will flow along the second filter 320 to the conveyor frame 330, and then be sent to the collection box 350 for collection through the conveyor box 340. Similarly, the other second filter 320 is used to collect the filtered dust into the collection box 800 for batch cleaning, thereby achieving the purpose of dual filtration and discharge.

[0033] Please see Figure 1 One side of the spark catcher 280 is sealed and connected to the fan unit 400, and one side of the fan unit 400 is sealed and connected to the powder packaging machine 500.

[0034] In one specific embodiment, the provided fan unit 400 allows the user to easily turn on the fan unit 400 via a controller, so that the fan unit 400 can transport out the dust overflowing from the powder packaging machine 500.

[0035] Please see Figure 1-3 Vibration motors 600 are installed on both sides of the protective box 100, a funnel 700 is installed in the middle of the inner wall of the protective box 100, and a collection box 800 is movably connected to the bottom of the inner wall of the protective box 100.

[0036] In one specific embodiment, the collection box 800 allows users to remove and process the dust once it is full, thus improving work efficiency.

[0037] Please see Figure 1 The protective box 100 is hinged to a protective door 900 at one end, and a second handle 1000 is provided at one end of the protective door 900.

[0038] In one specific embodiment, a second handle 1000 is provided to facilitate opening the protective door 900 during use, so as to take out the collection box 800 inside the protective box 100.

[0039] Please see Figure 3 One side of each of the two conveyor frames 330 corresponds to one of the two second filters 320, and the bottom of the electric valve 260 is sealed and connected to the protective box 100.

[0040] In one specific embodiment, the provided conveyor frame 330 facilitates the collection of dust that cannot be filtered by the second filter screen 320 during use.

[0041] Please see Figure 1 The second handle 1000 has a door lock inside, and the protective box 100 has a controller at the top corner.

[0042] In one specific embodiment, the door lock allows for easy unlocking with a key and opening of the protective door 900 via the second handle 1000, thereby improving work efficiency.

[0043] Please see Figure 1-4 The ion fan 220, nitrogen generator 240, electric valve 260, spark catcher 280, fan unit 400, powder packaging machine 500 and vibration motor 600 are all electrically connected to the controller, and the controller is electrically connected to an external power supply.

[0044] In one specific embodiment, the included controller facilitates power control of the electrical equipment during use, ensuring that the equipment is powered on when needed, thus avoiding situations where power cannot be supplied when required.

[0045] In operation, the ion fan 220, when collecting dust, is activated by the controller along with the nitrogen generator 240, electric valve 260, and spark arrester 280. The ion fan 220, through its built-in high-voltage generator, ionizes the air, generating a large number of positive and negative ions. These ions are then dispersed into the air by the fan, creating an airflow of positive and negative charges. This neutralizes the static charge on object surfaces, effectively reducing static electricity buildup caused by friction between dust and equipment, thus lowering the risk of explosion. Next, the nitrogen generator 240 produces nitrogen, which is then delivered through the delivery pipe 250 and electric valve 260 into the protective enclosure 100 to reduce the oxygen concentration and suppress the possibility of explosion. Finally, the spark arrester 280 intercepts and extinguishes any sparks entering the enclosure. The protective box 100 is designed to prevent sparks from igniting the internal dust, thus preventing dust explosions. The dust generated by the powder packaging machine 500 is then fed into the conveying chamber 270 by the fan unit 400, and then into the funnel 700. The dust falls onto one of the second filter screens 320. The operator then activates the vibration motor 600 via the controller, causing it to vibrate and filter the dust through the filter screen. Larger particles that cannot be filtered flow down the second filter screen 320 to the conveyor frame 330, and finally into the collection box 350 via the conveyor box 340. Similarly, the other second filter screen 320 filters the dust, which then flows into the collection box 800 for collection and batch cleaning, achieving a dual-filtration discharge.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
