Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, specifically to a low-noise dust removal device for glass powder crushing workshops. Background Technology

[0002] Glass powder is a powdered material made from block or granular glass or waste glass. It has moderate hardness and good chemical stability, and is widely used in ceramic glazes, coatings, electronic packaging, abrasives and other fields. Its performance depends on particle size distribution, purity and sphericity (required for high-end applications). In glass powder crushing, attention should be paid to the equipment material (such as stainless steel or agate) to prevent impurity contamination, moisture should be controlled through drying, and dust protection should be done to ensure that the product meets the purity and fineness requirements of downstream applications.

[0003] Currently, in the dust removal operations of glass powder crushing workshops, traditional dust hoods mostly rely on a single suction path through the main pipe. This can easily lead to dust escape due to uneven local negative pressure. However, when suction is only performed through the main pipe, the limited suction range of the main pipe makes it difficult to form a uniform and sufficient negative pressure field for the entire dust-generating area. In local areas that are far from the suction port of the main pipe or where there are equipment structures that obstruct the flow, uneven negative pressure can easily occur, causing a large amount of dust to escape from these areas with weak negative pressure into the workshop air, thus affecting the dust removal effect of the device. Utility Model Content

[0025] 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.

[0026] Please see Figures 1-5 This utility model provides a new technical solution:

[0027] The upper end of the main dust removal pipe 1 is fixedly installed with the dust removal connection pipe 2, and the lower end is fixedly connected with the dust removal hood 3; as the main channel for dust transportation, it is responsible for transporting the glass dust collected by the dust removal hood 3 to the subsequent dust removal system, and is the core path of dust flow.

[0028] One end of the dust removal connecting pipe 2 is fixedly installed at the upper end of the main dust removal pipe 1, and the other end is connected to the dust removal equipment outside the workshop; it plays a "transitional connection" role to ensure that the dust in the main dust removal pipe 1 can be smoothly introduced into the subsequent processing equipment and avoid dust accumulation at the pipe connection point.

[0029] The dust hood 3 is hood-shaped, with its upper end fixedly connected to the lower end of the main dust removal pipe 1. An annular hole 4 is opened at the lower end of its outer surface. A conical plate 10 is fixedly installed on the inner wall by connecting bolts 13, and a buffer pad 15 is fixedly installed on the lower surface. It is used to directly cover the dust-generating area of ​​the glass powder crushing equipment, providing a basis for subsequent suction.

[0030] The annular hole 4 is an annular groove structure opened at the lower end of the outer surface of the dust collector 3, and is fixedly connected to the negative pressure plate 7 inside; it provides a precise installation position for the negative pressure plate 7, and at the same time ensures that the structure of the negative pressure plate 7 and the dust collector 3 are compatible, preventing dust from escaping from the installation gap;

[0031] The water inlet pipe 5 is installed on the outer surface of the main dust removal pipe 1, and the lower surface has an installation hole 9 corresponding to the position of the auxiliary dust removal pipe 8. It only provides a water flow channel for cleaning the auxiliary dust removal pipe 8 by connecting to an external water source during shutdown, and does not directly participate in the dust removal process.

[0032] The water pipe 6 is fixedly installed inside the mounting hole 9 of the water inlet pipe 5, and its lower end passes through the corresponding auxiliary dust removal pipe 8; it plays the role of "water flow guide", accurately delivering the cleaning water in the water inlet pipe 5 to the inside of each auxiliary dust removal pipe 8, specifically flushing the glass powder dust remaining on the inner wall of the pipe, and preventing the pipe from being blocked.

[0033] The negative pressure plate 7 is an overall ring-shaped plate structure, which is fixedly connected to the inside of the annular hole 4. The lower surface is provided with a negative pressure dust collection groove 14, and the upper surface is fixedly installed with multiple auxiliary dust collection pipes 8 in a ring array. By utilizing its own structure in conjunction with the negative pressure of the main dust collection pipe 1, a uniform negative pressure field is formed at the negative pressure dust collection groove 14, which expands the dust adsorption range and gathers the dispersed glass powder dust in the dust collection hood 3 to the auxiliary dust collection pipes 8.

[0034] The lower end of the auxiliary dust removal pipe 8 is fixedly installed on the upper surface of the negative pressure plate 7, and the upper end extends into the interior of the main dust removal pipe 1; as an "auxiliary dust suction channel", it works with the main dust removal pipe 1 to form a "main-auxiliary synergy" suction structure, which transports the dust collected by the negative pressure plate 7 to the main dust removal pipe 1, reducing dust escape and improving dust removal efficiency. When the machine stops, the water flow introduced by the water pipe 6 can clean the residual dust inside.

[0035] The mounting hole 9 is a circular hole on the lower surface of the water inlet pipe 5, and its position corresponds one-to-one with the auxiliary dust removal pipe 8. The water pipe 6 is fixedly installed inside; it provides precise installation positioning for the water pipe 6 and ensures that the water pipe 6 can be aligned with the auxiliary dust removal pipe 8.

[0036] The conical plate 10 is fixedly installed on the inner wall of the dust collector 3 by connecting bolts 13. Two positioning rods 16 are fixedly connected to the upper surface, and rubber pads 11 are fixedly installed on the inner surface; the whole is conical in shape.

[0037] The rubber pad 11 is fixedly installed on the inner surface of the conical plate 10 and fits against the outlet edge of the glass powder crushing equipment; its core function is noise reduction, using the elasticity and damping properties of rubber to absorb the vibration noise during equipment operation.

[0038] The threaded groove 12 is formed on the outer surface of the dust collector hood 3 with internal threaded holes, the number of which is the same as that of the connecting bolt 13. The internal thread is used to install the connecting bolt 13; it provides a threaded mating base for the connecting bolt 13, ensuring that the connecting bolt 13 can stably fix the conical plate 10, and at the same time facilitates the subsequent disassembly and adjustment of the position of the conical plate 10.

[0039] The connecting bolt 13 is threaded inside the threaded groove 12 of the dust collector hood 3, and the thread extends into the interior of the conical plate 10; it serves as a "fixed connection", firmly fixing the conical plate 10 to the inner wall of the dust collector hood 3, while also facilitating disassembly and maintenance;

[0040] The buffer pad 15 is fixedly installed on the lower surface of the dust cover 3 and is made of elastic material; during the installation or transportation of the device, it buffers the impact force of the dust cover 3 on the ground and equipment, and prevents the dust cover 3 from being deformed due to bumps.

[0041] The lower end of the positioning rod 16 is fixedly connected to the upper surface of the conical plate 10, and the upper end slides through to the top of the dust cover 3; it plays a "positioning guide" role when installing the conical plate 10, ensuring that the conical plate 10 always remains vertical or at a preset angle.

[0042] Furthermore, when the device is started, the fan (not shown, a conventional component) at the rear end of the main dust removal duct 1 operates, forming a stable negative pressure inside the main dust removal duct 1 and the dust removal hood 3. At this time, the dust generated by the glass powder crushing dust generation point below the dust removal hood 3 will accumulate inside the dust removal hood 3 under the action of negative pressure, initially achieving "source adsorption" of dust. In the auxiliary mechanism, the negative pressure plate 7 is fixed in the annular hole 4 at the lower end of the outer surface of the dust removal hood 3, and the negative pressure dust suction groove 14 on its lower surface directly corresponds to the dust generation area. The negative pressure of the main duct will be synchronously transmitted to multiple auxiliary dust removal ducts 8 on the negative pressure plate 7. The upper end of the dust removal pipe 8 extends into the interior of the main dust removal pipe 1, creating a "locally enhanced negative pressure" in the negative pressure suction tank 14. This not only adsorbs the dust directly below the dust removal hood 3 but also captures fine dust that may escape from the edge gaps of the dust removal hood, expanding the dust collection range. When the device is shut down and it is necessary to clean the dust inside the auxiliary dust removal pipe 8, water or other cleaning media is introduced into the water inlet pipe 5. The media in the water inlet pipe 5 will flow into the corresponding auxiliary dust removal pipe 8 through multiple water pipes 6, rinsing the dust remaining in the auxiliary dust removal pipe 8 and preventing dust from accumulating inside the auxiliary dust removal pipe.

[0043] By setting up auxiliary mechanisms, the device can not only adsorb dust directly below the dust collector hood 3, but also capture fine dust that may escape from the gaps at the edge of the dust collector hood, expanding the dust collection range and increasing the dust removal effect. Furthermore, without affecting normal dust removal work, it provides a convenient way to clean the dust in the pipeline after shutdown, which helps to maintain the long-term stable operation of the dust removal device and improve dust removal efficiency and effect.

[0044] Example 1 (for reference) Figure 2 )

[0045] When the water inlet pipe is composed of a ring pipe and a connecting pipe, this type of water inlet pipe, which combines a single connecting pipe and a ring pipe, can be directly connected to the centralized water supply interface of the workshop through the connecting pipe. There is no need to arrange multiple additional water supply connection points. The installation is simple and can be quickly completed to connect with the existing water supply system of the workshop, meeting the needs of small workshops for simple and efficient installation and use.

[0046] Example 2 (for reference) Figure 5 )

[0047] When the water inlet pipe is composed of a ring pipe and four connecting pipes, the four connecting pipes arranged in a ring array can be connected to water supply interfaces at different locations, allowing for more flexible water intake from multiple directions. During shutdown cleaning, water can be introduced into some or all of the connecting pipes according to the actual water supply situation. This not only ensures a sufficient water supply, making the cleaning of auxiliary dust removal pipes more thorough, but also avoids problems such as insufficient water pressure from a single water supply interface affecting the cleaning effect, thus improving the applicability and cleaning reliability in large workshops with complex water supply layouts.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
