Description

Technical Field

[0001] This utility model relates to a dust removal technology, specifically a technology that uses multiple dust removal units to enhance dust removal. Background Technology

[0002] Pulse jet baghouse dust collectors are a very important type of dust collection equipment. However, when performing dust collection in crushing stone, some crushing processes generate a lot of dust, or the crushing area is large. In these cases, single-unit pulse jet baghouse dust collectors are less effective and struggle to meet the demands of high-intensity operations.

[0003] The main components of a pulse jet baghouse dust collector include an air inlet, a housing, filter cloths, a pulse jet assembly, and an air outlet. The air requiring purification enters the housing through the air inlet, moving upwards and being filtered and adsorbed by multiple filter cloths before being discharged from the top outlet. The pulse jet assembly periodically sprays air, blowing down the dust on the filter cloths for collection. The structure and working principle of pulse jet baghouse dust collectors are existing technology and will not be elaborated upon here.

[0004] Therefore, in principle, the filter cloth and pulse jet assembly are core components that can improve the overall efficiency of dust removal and cleaning. Thus, if this structure is improved as a whole, it can adapt to higher intensity dust removal work and address the problem of dust that is easily generated during crushing and cannot be cleaned up in time. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of the prior art, thereby providing a technology to enhance processing capabilities.

[0006] To achieve the above objectives, this utility model provides an enhanced dust removal device for crushing stone, which includes a pulse bag filter, a guide, and a dust discharge assembly.

[0007] A pulse bag filter dust collector has an outer shell, inside which are multiple sets of dust collector units arranged side by side. Each dust collector unit has multiple sets of pulse air inlet pipes and filter cloth. Multiple air inlets are located at the bottom of the outer shell.

[0008] The guide includes an adsorption fan, an inlet pipe, and an outlet pipe, wherein the upstream of the adsorption fan is connected to the inlet pipe, and the downstream of the adsorption fan is connected to the outlet pipe.

[0009] The dust discharge assembly includes a discharge motor, a spiral auger, and a collection pipe. The lower part of the outer casing has an arc-shaped collection pipe, the discharge motor is arranged on the side of the arc-shaped collection pipe, the spiral auger is arranged inside the arc-shaped collection pipe, the discharge motor is connected to the spiral auger, the spiral auger has a left spiral section, a right spiral section and a middle feeding section, and the collection pipe is arranged below the middle feeding section.

[0010] Preferably, the middle feeding section has multiple sets of scrapers arranged parallel to each other along the axial direction, and the collection pipe is arranged below the scrapers.

[0011] Preferably, the top of the housing has an opening, and a mounting plate is provided in the opening. The mounting plate is detachably connected to the mounting sidewall of the opening by screws.

[0012] Preferably, the outer shell has multiple sets of reinforcing ribs arranged vertically and horizontally, and the side of the outer shell has a climbing assembly, which has a climbing ladder and a circular guardrail structure.

[0013] Preferably, the guide has a mounting frame, the adsorption fan is arranged at the bottom inner side of the mounting frame, one side of the mounting frame has a ladder structure, and the upper part of the mounting frame has a mounting platform. The upper part of the mounting platform has an upper outlet pipe, which is connected to the lower discharge pipe.

[0014] Preferably, the collecting pipe has a hopper section and a discharge pipe, the discharge pipe being arranged laterally and having outlets on both sides.

[0015] Preferably, the middle feeding section has a scraping brush.

[0016] Preferably, each set of pulse inflation tubes has an inflation tube main pipe, branch pipes and inflation heads. Multiple sets of the branch pipes are arranged on the inflation tube main pipe, and multiple sets of inflation heads are located below the branch pipes. Each set of inflation heads is matched with the top of a single filter cloth.

[0017] The beneficial effects of this invention are as follows: Multiple sets of parallel pulse air inflators are integrated into the outer casing, thus improving dust removal efficiency as needed. Multiple air inlets allow the air to be treated to be connected to different inlets, and then purified at the pulse air inflators. This easily handles even the large amounts of dust generated during high-power stone crushing. Furthermore, the use of the same set of equipment for both air inlet and outlet facilitates centralized management and saves space. Compared to multiple independent processing devices, this not only improves the centralized processing capacity of stone crushing pollutants and gases but also offers a more rational spatial layout and occupies less space.

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1:

[0030] like Figures 1 to 4 As shown in the figure, an enhanced dust removal device for crushing stone in this embodiment includes a pulse bag dust collector 1, a guide 2, and a dust discharge assembly 3.

[0031] The pulse bag dust collector 1 has an outer shell 11, inside which are multiple sets of dust collector units 12 arranged side by side. Each dust collector unit 12 has multiple sets of pulse air charging pipes 121 and filter cloth 122. Multiple sets of air inlets 13 are located below the outer shell 11.

[0032] The guide 2 has an adsorption fan 21, an inlet pipe 22 and an outlet pipe 23, with the upstream of the adsorption fan 21 connected to the inlet pipe 22 and the downstream of the adsorption fan 21 connected to the outlet pipe 23.

[0033] The dust discharge assembly 3 has a discharge motor 31, a spiral auger 32, and a collection pipe 33. The lower part of the outer shell 11 has an arc-shaped collection pipe 34. The discharge motor 31 is arranged on the side of the arc-shaped collection pipe 34. The spiral auger 32 is arranged inside the arc-shaped collection pipe 34. The discharge motor 31 is connected to the spiral auger 32. The spiral auger 32 has a left spiral section 321, a right spiral section 322, and a middle feeding section 323. The collection pipe 33 is arranged below the middle feeding section 323.

[0034] Multiple sets of pulse inflation pipes 121 are arranged side-by-side inside the outer casing 11. These pulse inflation pipes 121 are independently controlled, for example, in groups of 2, 3, or 4. This increases the gas processing capacity, and the side-by-side arrangement improves space utilization, avoiding the space-consuming problem of piecing together individual devices. Furthermore, the centralized placement of the inlet and outlet further saves space. In actual use, 2, 3, or 4 sets of pulse inflation pipes 121 can be activated according to the processing power. Additionally, there are multiple air inlets 13, allowing the gas requiring purification to be delivered to different inlets 13 for processing, thereby improving the efficiency of handling large volumes of gas during stone crushing.

[0035] In addition, at the bottom position, the dust can be collected and gathered by the left spiral section 321 and the right spiral section 322. After being collected in the middle position, it is discharged through the middle discharge section 323 and discharged downward from the collection pipe 33.

[0036] Example 2:

[0037] Preferably, such as Figure 5 As shown, the middle feeding section 323 has multiple sets of scrapers 3231 arranged parallel to each other along the axial direction, and the collection pipe 33 is arranged below the scrapers 3231. The scrapers 3231 can better scrape off the collected dust and feed it off.

[0038] Preferably, Figure 2 In the case, the top of the outer casing 11 has an opening 113, and a mounting plate 114 is provided in the opening 113. The mounting plate 114 is detachably connected to the mounting side wall of the opening 113 by screws.

[0039] Preferably, the outer shell 11 has multiple sets of reinforcing ribs 111 arranged vertically and horizontally, and the side of the outer shell 11 has a climbing assembly 112, which has a climbing ladder 1121 and a circular guardrail structure 1122.

[0040] Preferably, combined with Figure 6 As shown, the guide 2 has a mounting frame 24, with the adsorption fan 21 installed at the bottom inner side of the mounting frame 24. One side of the mounting frame 24 has a ladder structure 25, and the upper part of the mounting frame 24 has a mounting platform 26. The upper part of the mounting platform 26 has an upper outlet pipe 27, which is connected to the lower discharge pipe 23. The mounting frame 24 facilitates the fixing and stabilization of the entire structure, especially the fixing of the upper outlet pipe 27. The mounting platform 26 facilitates the disassembly or connection of the upper outlet pipe 27 and the discharge pipe 23. The upper outlet pipe 27 allows the air to be expelled from a higher position, which is necessary in actual production where the air needs to be discharged from the top of the factory building or a high point on the side wall. The mounting frame 24 facilitates the extension of the pipe.

[0041] Preferably, combined with Figure 7 As shown, the collecting pipe 33 has a hopper section 331 and a discharge pipe 332. The discharge pipe 332 is arranged horizontally, and outlets 333 are arranged on both sides of the discharge pipe 332. Materials can be discharged from the outlets 333 on both sides, and either outlet 333 is acceptable, which facilitates the replacement of the receiving boxes on both sides. It also facilitates clearing from the other side when one side is blocked.

[0042] Preferably, the middle feeding section 323 has a scraping brush 3232. The scraping brush can better sweep dust from the curved wall and collect it in the hopper section 331 below.

[0043] Preferably, each pulse inflation tube 121 has an inflation main tube 1211, branch tubes 1212, and inflation heads 1213. Multiple branch tubes 1212 are arranged on the inflation main tube 1211, and multiple inflation heads 1213 are located below the branch tubes 1212. Each inflation head 1213 engages with the upper part of a single filter cloth 122. The inflation main tube 1211 is independently controlled for inflation, thus achieving a higher power processing method. Inflation causes the inflation heads 1213 to spray air onto the filter cloth 122, causing dust to be collected downwards. The specific principle of this process is prior art and will not be elaborated here.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
