Description

Technical fields:

[0001] This utility model relates to the field of material collection technology, specifically to a particle silicon filtration and collection device for dust removal pipelines. Background technology:

[0002] In recent years, my country's silicon industry has developed rapidly, and the production and packaging of silicon materials have been generally upgraded to mechanization. While the production capacity has increased rapidly, the quality requirements for silicon materials have become increasingly stringent.

[0003] The produced polycrystalline silicon raw materials typically undergo crushing, screening, and mechanical packaging to become the final product. During the crushing, screening, and mechanical packaging processes, silicon dust is generated. Therefore, a dust collection pipe is installed at each stage. These dust collection pipes eventually converge into a single dust collection duct. The dust collection duct uses a fan to generate negative pressure, thereby sucking away and discharging the silicon dust generated in each stage through the dust collection pipes. However, this silicon dust contains some granular silicon material. Due to its own weight and the relatively long length of the dust collection duct, a thick layer of silicon material usually accumulates inside the dust collection duct. This typically requires manual cleaning by entering the dust collection duct, which is very inconvenient.

[0004] Therefore, this application proposes a technical solution to reduce the frequency of manual cleaning. Utility model content:

[0005] The purpose of this invention is to provide a particulate silicon filtration and collection device for dust removal pipelines, so as to solve the problems mentioned in the background art.

[0006] This utility model is implemented by the following technical solution:

[0007] A particulate silica filtration and collection device for a dust removal pipeline includes a dust removal pipeline with multiple collection devices installed on it. Each collection device includes a first dust removal pipeline, along which a tee pipe, a filter plate, and a second dust removal pipeline are sequentially installed. The tee pipe is T-shaped, with its inlet end and the flange end of the first dust removal pipeline fixedly connected by bolts. The outlet end of the tee pipe and the flange end of the second dust removal pipeline are also fixedly connected by bolts. The second dust removal pipeline has an inclined cross-section with a groove within it. A filter plate is inserted into the groove, and the filter holes of the filter plate are longitudinally oriented. An annular retaining ring is inclinedly fixed within the tee pipe near its outlet end, clamping the filter plate within the groove. The discharge end of the tee pipe and the flange end of the collection cylinder are fixedly connected by bolts.

[0008] Preferably, four posts are fixed on the filter plate, and the posts are at a 45-degree angle to the surface of the filter plate. The groove has holes corresponding to the four posts, so that the posts are inserted into the holes.

[0009] Preferably, the filter holes of the filter plate are opened longitudinally and perpendicular to the insertion post, and the filter holes of the filter plate are located above the discharge end of the three-way pipe.

[0010] The advantages of this invention are: its structure is relatively simple, and multiple collection devices can be installed on the dust removal pipeline. The filter plates intercept the silicon powder particles in the dust removal pipeline, causing the intercepted silicon powder to fall into the collection cylinder. While cleaning, workers can also enter the interior through the discharge end of the three-way pipe to clean the filter holes of the filter plates. Using this device can significantly reduce the frequency of manual cleaning, and the collection of silicon powder particles is also more convenient. Attached image description:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-8 This utility model provides a technical solution for a particulate silicon filtration and collection device for dust removal pipelines:

[0022] A particulate silicon filtration and collection device for dust removal pipeline includes a dust removal pipeline. Since the dust removal pipeline is relatively long, the amount of silicon powder particles actually sucked up will gradually decrease with the side length of the dust removal pipeline. Therefore, multiple collection devices need to be installed on the dust removal pipeline to collect the silicon powder particles intercepted and deposited inside the pipeline within different length ranges, thereby reducing the frequency of manual cleaning.

[0023] The collection device includes a first dust removal pipe 1, a three-way pipe 2, a filter plate 3, and a second dust removal pipe 4 installed sequentially along the dust discharge direction of the first dust removal pipe 1. The three-way pipe 2 has a "T" shape structure. The air inlet end 2.1 of the three-way pipe 2 and the flange end of the first dust removal pipe 1 are fixedly connected by bolts. The air outlet end 2.2 of the three-way pipe 2 and the flange end of the second dust removal pipe 4 are fixedly connected by bolts.

[0024] To facilitate quick disassembly of the filter plate 3 later, four inserts 3.1 are fixed on the filter plate 3. The inserts 3.1 are at a 45-degree angle to the surface of the filter plate 3. Since the silicon powder particles are transported horizontally in the pipeline, if the filter holes 3.2 are opened horizontally, they are prone to clogging after long-term use due to the influence of silicon dust particles, which will affect the negative pressure effect of the fan. If the filter holes 3.2 of the filter plate 3 are opened vertically, the silicon dust particles will be intercepted, so that the large silicon powder particles will not be directly stuck in the filter holes 3.2, but will fall out first, which will prolong the time before clogging occurs and reduce the frequency of filter plate 3 replacement.

[0025] To secure the filter plate 3, the second dust removal pipe 4 has a 45-degree inclined cut surface 4.1, with a groove 4.2 inside the cut surface 4.1. The groove 4.2 is used to place the filter plate 3, and insertion holes 4.3 corresponding to the four insertion posts 3.1 are opened in the groove 4.2, so that the insertion posts 3.1 can be inserted into the insertion holes 4.3. To prevent the filter plate 3 from loosening, an annular retaining ring 2.3 is fixed at a 45-degree angle inside the three-way pipe 2 near its outlet end 2.2, so that the filter plate 3 is clamped in the groove 4.2 by the annular retaining ring 2.3.

[0026] In order to allow the intercepted silicon powder particles to fall into the collection cylinder 5, the filter holes 3.2 of the filter plate 3 are set above the discharge end of the three-way pipe 2. The discharge end of the three-way pipe 2 and the flange end of the collection cylinder 5 are fixedly connected by bolts. Every certain period of time, the silicon powder collected in the collection cylinder 5 can be collected by removing the collection cylinder 5. At the same time, the staff can also enter the interior through the discharge end of the three-way pipe 2 to clean the filter holes 3.2 of the filter plate 3.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
