Description

Technical Field

[0001] This utility model relates to the field of belt conveyor dust removal technology, and is a belt conveyor dust removal device. Background Technology

[0002] In the production process of calcium carbide plants, belt conveyors are widely used to transport various raw materials and finished products. However, due to the extremely fine and sticky dust generated during calcium carbide production, this dust adheres firmly to the surface of the belt and accumulates under the idlers during the return trip. Especially in the unique environment of calcium carbide plants, the dust problem is particularly severe, not only affecting the normal operation of the belt conveyors but also causing significant pollution to the workshop environment. Existing cleaning methods mainly rely on manual labor, requiring workers to periodically enter the harsh environment for cleaning operations. This is not only extremely labor-intensive but also poses a serious threat to workers' health due to long-term exposure to dust, easily leading to occupational diseases such as respiratory illnesses.

[0003] Dust pollution in calcium carbide plants is not limited to the conveyor belt area. Due to the fineness and stickiness of the dust, it easily disperses throughout the workshop during conveyor belt operation, causing widespread environmental pollution. This pollution not only affects the cleanliness and aesthetics of the workshop but also negatively impacts air quality. Long-term exposure to this environment poses a serious threat to workers' health. Furthermore, dust accumulation under the return rollers of the conveyor belt, constantly rubbing against the belt surface, accelerates belt wear, shortens belt lifespan, and thus increases production costs and the operational burden on the company.

Detailed Implementation

[0017] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.

[0018] In this utility model, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a central A-axis method, and the positional relationships such as front, back, top, bottom, left, and right are determined based on the layout direction of the attached diagram in the instruction manual.

[0019] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0020] Example 1: As shown in the attached document Figure 1 , 2As shown in Figure 3, the belt conveyor cleaning device includes a belt conveyor, a dust collection box, and a dust blowing assembly. A dust collection box is provided on the outer side of the lower part of the conveyor belt 1 corresponding to the material discharge end of the belt conveyor. A dust blowing assembly is provided inside the dust collection box. The dust blowing assembly includes a dust blowing pipeline, a dust spray head 16, and an air inlet pipeline 9. The dust blowing pipeline is a ring pipeline, including an upper dust blowing pipeline 14 and a lower dust blowing pipeline 15. An upper dust blowing pipeline 14 is provided above the lower part of the conveyor belt 1. The upper dust blowing pipeline 14 is U-shaped with its opening facing downwards. A lower dust blowing pipeline 15 is provided below the lower part of the conveyor belt 1. The lower dust blowing pipeline 15 is U-shaped. The lower end of the upper dust blowing pipeline 14 and the upper end of the lower dust blowing pipeline 15 are fixedly connected together. Dust spray heads 16 are provided at intervals on the lower side of the upper dust blowing pipeline 14 and the upper side of the lower dust blowing pipeline 15. An air inlet pipeline 9 located outside the dust collection box is fixedly connected to the right side of the dust blowing pipeline. During operation, dust spraying heads 16 are installed on the lower side of the upper dust spraying pipeline 14 to clean the non-working surface of the conveyor belt 1; dust spraying heads 16 are installed on the upper side of the lower dust spraying pipeline 15 to clean the working surface of the conveyor belt 1; and a dust collection box is installed to collect the dust that falls from the conveyor belt 1. Depending on requirements, the lower end of the upper dust spraying pipeline 14 and the upper end of the lower dust spraying pipeline 15 can be fixed together using flange connections, facilitating connection and allowing them to be located outside the conveyor belt. Furthermore, although the non-working surface of the conveyor belt 1 does not directly participate in material transport, its cleaning is of paramount importance. Firstly, cleaning the non-working surface can significantly extend the belt's service life; accumulated dust will accelerate the wear of idlers and non-working surfaces, and may even scratch or corrode the belt surface, especially for some non-working surfaces without a protective rubber cover; regular cleaning can effectively reduce these damages and lower maintenance costs. Secondly, cleaning non-working surfaces helps improve the operating efficiency of the conveyor belt. Excessive dust accumulation increases belt resistance, leading to increased energy consumption and potentially causing the belt to slip on the idlers, affecting normal operation. Cleaning reduces operating resistance, ensuring stable operation of the conveyor belt and saving energy. Furthermore, cleaning non-working surfaces improves the workshop working environment. Dust accumulated during belt operation can be shaken off, causing dust pollution and harming worker health. Keeping non-working surfaces clean effectively reduces dust, improves air quality, and protects worker health. Finally, from a safety perspective, cleaning non-working surfaces eliminates potential fire hazards. Some dust is flammable, and excessive dust accumulation can pose a fire risk. Cleaning effectively reduces this risk and ensures production safety. In conclusion, cleaning the non-working surfaces of the conveyor belt is an important maintenance task, significant for extending equipment life, improving production efficiency, improving the working environment, and ensuring production safety, especially in harsh environments with high dust levels, such as calcium carbide plants.

[0021] The above-mentioned belt conveyor dust removal device can be further optimized and / or improved according to actual needs:

[0022] Example 2: As shown in the attached document Figure 1 , 2 As shown in Figure 3, the ash collection box includes a cover 12, a body 13, and a dust removal door.

The outer side of the body 13 has a through-hole dust removal port, and the outer side of the ash collection box corresponding to the dust removal port is equipped with a dust removal door. During use, the left opening 17 and the right opening 18 facilitate the installation of the cover 12 and the body 13 at the corresponding positions of the conveyor belt 1; the dust removal port is used to clean the dust collected in the ash collection box.

[0023] Example 3: As shown in the attached document Figure 1 , 2 As shown in Figure 3, the system also includes a dust removal assembly, which comprises a front column, a rear column, a fixing angle steel, and a dust removal felt 4. The front and rear columns are fixedly installed at intervals within the housing 13.

The lower front side of the horizontal mounting plate 2 is fixedly installed to the upper end of the front column, and the lower rear side of the horizontal mounting plate 2 is fixedly installed to the upper end of the rear column. A vertical mounting plate 3 with its upper end positioned above it is fixedly installed on the left side of the horizontal mounting plate 2, and a dust removal felt 4 with its upper end positioned above it is fixedly installed on the right side of the vertical mounting plate 3. During use, this embodiment is fixedly installed on the ground below the belt conveyor, so that the upper end of the dust removal felt 4 contacts the working surface of the belt. The dust removal felt 4 cleans the dust adhering to the working surface of the belt conveyor; by using a non-rigid dust removal felt 4, damage to the working surface of the belt is avoided during the dust removal process. Depending on the requirements, in order to ensure the dust removal effect, if the belt conveyor rotates clockwise, this embodiment can be installed on the lower right side of the belt conveyor; if the belt conveyor rotates counterclockwise, this embodiment can be installed on the lower left side of the belt conveyor. In addition, the front of the dust collection box is located in front of the belt conveyor, and the rear of the dust collection box is located behind the belt conveyor. With this arrangement, the dust removal felt 4 can scrape the maximum width of the belt conveyor, which can effectively reduce the situation of dust material being missed and scattered.

[0024] Example 4: As shown in the appendix Figure 1 , 2As shown in Figure 3, the front column includes a first outer cylinder 5, a first inner rod 6, a first fixing nut 7, and a first set screw 8. The rear column includes a second outer cylinder, a second inner rod, a second fixing nut, and a second set screw. The first outer cylinder 5 and the second outer cylinder are fixedly installed at intervals in the housing 13. The first outer cylinder 5 has a first inner rod 6 located above it at its upper end. At least two first mounting holes are evenly distributed along the circumference on the upper outer side of the first outer cylinder 5. A first fixing nut 7 is fixedly installed on the outer side of the first outer cylinder 5 corresponding to each first mounting hole. A first fixing nut 7 is fixedly installed inside the first fixing nut 7. A first set screw 8 is provided inside the second outer cylinder, with its upper end located above it.

The lower front side of the horizontal mounting plate 2 is fixedly installed together with the upper end of the first inner rod 6, and the lower rear side of the horizontal mounting plate 2 is fixedly installed together with the upper end of the second inner rod. During use, this design allows for adjustment of the height of the front and rear columns after the upper end of the cleaning felt 4 wears down, ensuring that the upper end of the cleaning felt 4 is always in contact with the working surface of the belt, thus extending the service life of the cleaning felt 4. This design cleverly solves the problem of reduced cleaning effect after the cleaning felt 4 wears down. By adjusting the column height, continuous and effective contact between the cleaning felt 4 and the belt can be ensured, guaranteeing the cleaning effect. This design avoids downtime caused by frequent replacement of the cleaning felt 4 due to wear, improving production efficiency. At the same time, it also reduces the consumption of the cleaning felt 4, lowering operating costs.

[0025] Example 5: As shown in the attached document Figure 1 , 2 As shown in Figure 3, the system also includes fastening bolts 10 and fastening nuts 11. The vertical mounting plate 3 has at least two through-holes on each side, spaced at intervals. Corresponding to each of the first fastening holes, the cleaning felt 4 has a second through-hole. Each second fastening hole has a fastening bolt 10 with its left end passing through the corresponding first fastening hole. A fastening nut 11 is fixedly installed on the left end of the fastening bolt 10. This arrangement facilitates the installation of the cleaning felt 4 with the vertical mounting plate 3 during use, and allows for replacement of the cleaning felt 4 after wear.

[0026] Example 6: As attached Figure 1 , 2As shown in Figure 3, the system also includes a dust collector connector, a dust collection duct, a bag filter, and an induced draft fan. A dust collector interface is located on the outside of the housing 13, and a dust collector connector is located on the outside of the housing 13 corresponding to the dust collector interface position. The inlet end of the dust collection duct is connected to the dust collector connector, and the outlet end of the dust collection duct is connected to the bag filter. The outlet end of the bag filter is connected to the induced draft fan. During use, this setup allows dust generated during the cleaning process to be drawn away through the dust collector connector and dust collection duct, filtered by the bag filter, and the purified air is discharged by the induced draft fan, effectively reducing dust pollution during cleaning operations.

[0027] The above technical features constitute the preferred embodiment of this utility model, which has strong adaptability and the best implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
