[0021] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] like Figures 1-3 As shown, it illustrates an industrial dust collection box according to one embodiment of the present invention, including... Storage box 1, with connecting pipe 2 installed on the side wall of storage box 1; Air intake filter assembly 3 is installed inside the storage box 1; Locking and sealing assembly 4 is provided on the upper surface of storage box 1; The air intake filter assembly 3 includes a filter plate 3-1, which is disposed inside the storage box 1. An interceptor plate 3-2 is provided on the side wall of the filter plate 3-1. One end of the interceptor plate 3-2 is attached to the inner side wall of the storage box 1. A collection port 3-3 is provided at one end of the storage box 1. A collection bag binding groove 3-4 is provided on the outer side wall of the collection port 3-3.

[0023] In some examples, the implementation of this industrial vacuum cleaner box needs to follow the process of "basic construction - core component installation - sealing and debugging" to ensure that each component fits precisely and achieves efficient dust collection and sealing filtration functions. The tools required for overall assembly include: Allen wrench, rubber hammer, sealant, tape measure, level, and fasteners (bolts, pins, etc.) for each component.

[0024] First, place storage box 1 on a level surface and adjust the level of the box using a level. If the installation site is slightly uneven, you can put a rubber pad at the bottom of the box to ensure it is level and reduce vibration and noise during vacuuming.

[0025] Place the filter plate 3-1 inside the storage box 1, ensuring that the edge of the filter plate 3-1 is aligned with the groove on the inner wall of the box. Then, gently tap the edge of the filter plate 3-1 with a rubber mallet to ensure it is fully engaged in the groove. Next, install the interceptor plate 3-2 on the side wall of the filter plate 3-1. One end of the interceptor plate 3-2 should fit tightly against the inner wall of the storage box 1, with sealant applied to the joint. The other end should be fixed to the filter plate 3-1 with rivets to ensure that the interceptor plate 3-2 can effectively prevent dust from overflowing from the gap between the filter plate 3-1 and the box wall.

[0026] refer to Figure 1 and Figure 3 In some embodiments, the air intake filter assembly 3 further includes a flow guide slope 3-5 at the bottom of the storage box 1, a filter rail 3-6 at the upper end of the flow guide slope 3-5, filter grooves 3-7 at the intervals of the filter rail 3-6, a flow guide pipe 3-8 inside the storage box 1, and a flow guide valve 3-9 on the side wall of the flow guide pipe 3-8.

[0027] In some examples, the filter bar 3-6 is placed on the upper surface of the drainage slope 3-5. The mounting holes of the filter bar 3-6 must be aligned with the positioning holes on the drainage slope 3-5. After installation, the flatness of the filter bar 3-6 must be checked to ensure that it fits tightly with the drainage slope 3-5 and that the filter groove 3-7 is not blocked, so that dust can fall smoothly into the drainage slope 3-5 through the filter groove 3-7. The drainage slope 3-5 is welded to the bottom of the storage box 1. After welding, the weld seam must be ground to ensure that the surface is smooth and burr-free. Then, the guide pipe 3-8 is installed on the pre-set pipeline inside the storage box 1. The connection between the guide pipe 3-8 and the box body must be sealed with sealant. After the sealant has cured, the guide valve 3-9 is installed. The handle of the guide valve 3-9 should face the outside of the box body for easy operation.

[0028] like Figures 1-3 As shown, on the other hand, this utility model also provides a locking and sealing assembly 4, including a sealing cover 4-1, which is fastened to the upper end face of the storage box 1. A sealing ring 4-2 is provided on the lower end face of the sealing cover 4-1. A locking opening 4-3 is opened on the sealing ring 4-2. A locking block 4-4 is inserted into the locking opening 4-3. A locking strip 4-5 is provided at one end of the locking block 4-4. A meshing tooth 4-6 is provided on the inner side wall of the locking strip 4-5. A drive gear 4-7 is provided at the bottom of the sealing cover 4-1. The drive gear 4-7 meshes with the meshing tooth 4-6. In some examples, the sealing ring 4-2 is pasted onto the lower end face of the sealing buckle 4-1. The size of the sealing ring 4-2 must match the opening size of the upper end face of the storage box 1. A special rubber adhesive must be used for pasting to ensure that there are no air bubbles or misalignment between the sealing ring 4-2 and the buckle. After the adhesive has cured, the sealing buckle 4-1 is fastened onto the upper end face of the storage box 1. Check whether the sealing ring 4-2 fits the upper end face of the storage box 1 completely. If there is a gap, the position of the sealing ring 4-2 needs to be readjusted. Insert the locking block 4-4 into the pre-set locking hole 4-3 on the sealing ring 4-2. One end of the locking block 4-4 needs to extend out of the outer side of the sealing buckle 4-1, and the other end needs to be welded and fixed to the locking strip 4-5. The inner side wall of the locking strip 4-5 needs to be machined with meshing teeth 4-6 to ensure smooth meshing with the drive gear 4-7. After installation, the locking strip 4-5 needs to be pushed to check whether its movement is flexible and without jamming.

[0029] refer to Figure 1 and Figure 3 In some embodiments, the locking and sealing assembly 4 further includes a rotating shaft 4-8 disposed on the drive gear 4-7, one end of the rotating shaft 4-8 extending out of the sealing buckle cover 4-1, and a rotating disc 4-9 disposed on the upper end of the rotating shaft 4-8.

[0030] In some examples, the drive gear 4-7 is installed at the bottom of the sealing cover 4-1. The center hole of the drive gear 4-7 needs to be aligned with the shaft hole on the sealing cover 4-1. Then, the screw shaft 4-8 is inserted. The screw shaft 4-8 and the drive gear 4-7 are connected by a key to ensure stable power transmission. After one end of the screw shaft 4-8 extends out of the sealing cover 4-1, a screw plate 4-9 is installed on its upper end. The screw plate 4-9 and the screw shaft 4-8 are fixed by a set screw.

[0031] For example, such as Figure 2 As shown, the outer wall of the connecting pipe 2 is provided with a positioning groove 5, and the outer wall of the connecting pipe 2 is provided with a plug ring 6, which is located outside the positioning groove 5.

[0032] In some examples, the connecting pipe 2 is installed at the pre-set mounting hole on the side wall of the storage box 1. First, two turns of Teflon tape are wrapped around the positioning groove 5 on the outer side wall of the connecting pipe 2 to enhance the sealing. Then, the connecting pipe 2 is inserted into the mounting hole to ensure that the plug ring 6 is completely fitted to the outer side wall of the box.

[0033] For example, such as Figure 2 As shown, a sealing ring 4-2 gasket is provided on the outer wall of the plug ring 6, and a sealing fit is formed between the sealing ring 4-2 gasket and the plug ring 6.

[0034] In some examples, the sealing ring 4-2 gasket is fitted onto the outer wall of the plug ring 6. Before installation, the surface of the plug ring 6 should be cleaned to remove oil and impurities. Then, the sealing ring 4-2 gasket is slowly fitted in to ensure that the gasket is not misaligned with the plug ring 6. Finally, the edge of the gasket is pressed by hand to make it fit completely against the plug ring 6 to prevent airflow from leaking out of the gap.

[0035] For example, such as Figure 2 As shown, a large particle blocking mesh 8 is installed inside the collection port 3-3, and the large particle blocking mesh 8 is sealed and fitted with the collection port 3-3.

[0036] In some examples, a collection port 3-3 is opened at one end of the storage box 1. The outer wall of the collection port 3-3 needs to be machined with a collection bag binding groove 3-4 for fixing the collection bag. A large particle blocking net 8 is installed inside the collection port 3-3. The edge of the blocking net needs to be sealed and fitted to the inner wall of the collection port 3-3. It can be fixed by welding or bolts. After fixing, the gap between the blocking net and the collection port 3-3 needs to be filled with sealant to prevent large particle impurities from bypassing the blocking net and entering the interior of the storage box 1.

[0037] For example, such as Figure 2 As shown, the storage box 1 has a connecting plate 9 inside, and the connecting plate 9 is connected to the cleaning plate 10 by a pin. The inner side wall of the storage box 1 is provided with a support frame 11, which is located on the lower end face of the cleaning plate 10.

[0038] In some examples, a connecting plate 9 is welded inside the storage box 1. The position of the connecting plate 9 should correspond to the lower part of the filter plate 3-1. Then, the cleaning plate 10 is connected to the connecting plate 9 by a pin. The pin should be coated with anti-rust oil to ensure that the cleaning plate 10 can rotate flexibly. Finally, a support frame 11 is installed on the inner side wall of the storage box 1. The support frame 11 should be in close contact with the lower end face of the cleaning plate 10 to support the cleaning plate 10 and prevent the cleaning plate 10 from sagging due to the weight of dust.

[0039] During operation, the industrial dust collection box utilizes a collaborative mechanism of "negative pressure diversion - multi-stage filtration - directional collection - sealing and locking" to achieve efficient collection and filtration of dust and particulate impurities in industrial settings. The core working logic revolves around airflow movement and impurity separation, and the specific principles are as follows: I. Negative pressure airflow drive: the driving force behind dust intake The industrial dust collection box needs to be used in conjunction with an external negative pressure device. A negative pressure environment is established through the connecting pipe 2, which is the core power source for dust suction. When the external negative pressure device is started, a stable negative pressure will be formed inside the collection box 1 (the normal negative pressure value is -0.03~-0.05MPa). At this time, an air pressure difference is generated inside and outside the collection box 1: the external dust-laden airflow enters the connecting pipe 2 through the external pipe under the action of the air pressure difference, and then flows into the collection box 1 through the connecting pipe 2.

[0040] During this process, the sealing ring 4-2 on the outside of the connecting pipe 2 fits tightly with the external pipe, which can prevent airflow from leaking from the pipe connection and ensure that all external dust-laden airflow can enter the collection box 1, avoiding negative pressure loss that leads to a decrease in dust collection efficiency; at the same time, the positioning groove 5 of the connecting pipe 2 cooperates with the clamp of the external pipe to fix the pipe position and prevent airflow impact from causing pipe displacement.

[0041] II. Multi-stage filtration: the core step in impurity separation After the dust-laden airflow enters the collection box 1, it will pass through a three-stage filtration process: "large particle pre-interception - fine filtration - residual interception," achieving stratified separation of impurities of different particle sizes. The specific process is as follows: Large particle pre-interception (blocking mesh at collection port 3-3): The dust-laden airflow first comes into contact with the large particle blocking mesh 8 inside collection port 3-3. The mesh openings of the blocking mesh can block impurities with a particle size greater than 5mm (such as metal shavings and blocky waste). These large particles will fall directly into the collection bag below collection port 3-3 due to gravity (fixed by the collection bag binding groove 3-4 to prevent impurity leakage), completing the first stage of filtration and preventing large particles from entering subsequent components and causing blockage or damage.

[0042] Fine filtration (filter plate 3-1 + interceptor plate 3-2): The pre-intercepted airflow continues to flow into the storage box 1 and enters the filter plate 3-1 area. The filter plate 3-1 uses a high-efficiency filter material that can intercept fine dust particles larger than 0.3μm (such as flour and metal powder), achieving a second stage of fine filtration. At the same time, the interceptor plate 3-2 on the side wall of the filter plate 3-1 fits tightly against the inner side wall of the storage box 1, preventing the airflow from bypassing the filter plate 3-1 through the gap between the filter plate 3-1 and the box wall, ensuring that all airflow must pass through the filter plate 3-1 for filtration, and preventing unfiltered airflow from being directly discharged.

[0043] Residual interception (filter bar 3-6 + diversion slope 3-5): Some tiny dust particles attached to the airflow will impact the filter bar 3-6 due to inertia during the airflow process (the round steel intervals of the filter bar 3-6 form a physical barrier), or flow with the airflow to the diversion slope 3-5 at the bottom of the collection box 1. The diversion slope 3-5 is designed with a 15° inclination, and the dust will slide down the slope and fall into the collection bag through the filter groove 3-7 of the filter bar 3-6, completing the third stage of residual interception and further improving the filtration effect.

[0044] III. Targeted Collection: Ensuring Centralized Impurity Treatment The filtered impurities are directed to a collection bag via a combination of gravity guidance and airflow assistance for centralized processing. Large particle and residual impurity collection: Impurities intercepted by the large particle blocking net 8 and residual dust guided by the filter rails 3-6 and the diversion slope 3-5 will fall directly into the collection bag. The collection bag is fixed by the binding groove, and the bag mouth and the collection port 3-3 are tightly sealed to prevent impurities from leaking during the collection process.

[0045] Collection of liquid and dust mixture: If the dust-laden airflow contains a small amount of liquid (such as oil or coolant), the liquid and dust will form a mixture. The mixture will flow with the airflow to the guide slope 3-5 and flow into the guide pipe 3-8 area at the bottom of the collection box 1. At this time, the guide valve 3-9 can be opened, and the mixture will be discharged to the external collection container through the guide pipe 3-8. This prevents the mixture from accumulating and deteriorating in the collection box 1, and also prevents the liquid from soaking the filter plate 3-1 and affecting the filtration effect.

[0046] In addition, the cleaning plate 10 inside the storage box 1 can assist in the collection of impurities: when too much dust accumulates on the surface of the filter plate 3-1, causing the filtration efficiency to decrease, the cleaning plate 10 can be rotated (rotating flexibly around the pin of the connecting plate 9). The cleaning plate 10 will scrape the surface of the filter plate 3-1, causing the accumulated dust to fall off and fall into the collection bag along the drainage slope 3-5, ensuring that the filter plate 3-1 continues to maintain a high-efficiency filtration state.

[0047] IV. Sealing and Locking: Ensuring Stable Negative Pressure Environment The locking and sealing assembly 4 maintains a negative pressure environment inside the storage box 1 through "double sealing + mechanical locking", ensuring stable operation of the dust collection and filtration process. Sealing ring 4-2 seal: The sealing ring 4-2 on the lower end face of the sealing buckle cover 4-1 fits tightly with the upper end face of the storage box 1, which can prevent external air from entering the storage box 1 (avoiding damage to the negative pressure) and at the same time prevent dust inside the storage box 1 from leaking to the external environment, thus achieving the first layer of sealing.

[0048] Mechanical locking (drive gear 4-7 + locking bar 4-5 + locking block 4-4): When the rotary disc 4-9 is rotated, the rotary shaft 4-8 drives the drive gear 4-7 to rotate. The drive gear 4-7 engages with the meshing teeth 4-6 of the locking bar 4-5, pushing the locking bar 4-5 to move. This, in turn, causes the locking block 4-4 to insert into the locking port 4-3 of the sealing ring 4-2, firmly fixing the sealing cover 4-1 to the storage box 1. This prevents the sealing cover 4-1 from loosening due to negative pressure, ensuring that the sealing cover 4-1 does not loosen under negative pressure and maintaining the second layer of locking seal.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
