Description

Technical Field

[0001] This utility model relates to the field of mullite production technology, and in particular to an air duct for mullite production. Background Technology

[0002] In the production process of mullite, ducts are used to transport air. However, the existing duct structure is relatively simple, usually consisting of a single pipe. When transporting air, this type of duct cannot effectively filter the air, causing impurities carried in the air to easily enter the production machine, affecting the production quality of mullite and the normal operation of the production equipment. In addition, the existing ducts are inconvenient to install and disassemble filter devices, increasing maintenance and time costs in the production process.

[0003] For example, in the prior art, the patent with authorization announcement number CN217887326U discloses an air duct for mullite production. This device filters the air entering the inner cavity of the air duct through a filter screen. When disassembly is required, simply rotate the movable ring. The movable ring drives the mounting rod to rotate until it is disengaged from the inner cavity of the positioning seat. Finally, pull the mounting ring outward to remove the filter screen. This air filtration can prevent impurities carried in the air from entering the production machine and facilitates the installation and removal of the filter screen.

[0004] Although the device is equipped with a filter to filter the air in the intake duct, there is no sealing device between the moving ring and the filter, or between the moving ring and the duct. Gaps exist between the moving ring, the filter, and the duct, allowing outside air to enter. This air cannot be filtered by the filter, causing impurities to enter the mullite production equipment and affecting the quality of the mullite. Therefore, a new duct for mullite production is designed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a duct for the production of mullite sand.

[0006] The technical problem to be solved by this utility model is to provide an air duct for the production of mullite, which solves the problem in the prior art that the air duct mesh installation point of the mullite air duct has poor sealing with the air duct, which makes it easy for impurities to enter the air duct and affect the quality of the mullite after production.

[0007] This utility model provides an air duct for mullite production, including an air duct installed on the housing of a mullite production equipment. An installation ring is installed at the right end of the air duct via an installation component. An inverted funnel-shaped screen is snapped onto the right side of the installation ring. A snap-fit ​​ring is fixedly installed on the left side of the inverted funnel-shaped screen. Positioning components for positioning the snap-fit ​​ring are provided on the snap-fit ​​ring and the installation ring. A limit ring is fixedly installed inside the installation ring. Sealing rubber rings are fixedly installed on both sides of the limit ring.

[0008] Preferably, the installation assembly includes positioning posts fixed to the upper and lower surfaces of the right end of the duct and inverted L-shaped slots formed above and below the installation ring. The inner side of the inverted L-shaped slot is provided with an embedding groove, and a spring is fixedly provided on the inner side of the embedding groove. A trapezoidal block is fixedly provided on the other end of the spring.

[0009] Preferably, the width of the inverted L-shaped groove is equal to the diameter of the positioning post.

[0010] Preferably, the trapezoidal block is in the shape of a right trapezoid, and when the spring is in its natural extended state, the trapezoidal block is fully embedded in the embedding groove at the end facing the inverted L-shaped slot opening, and when the spring is in its maximum compressed state, the trapezoidal block is fully embedded in the embedding groove.

[0011] Preferably, when the positioning post is engaged with the bent part of the inverted L-shaped groove, the sealing rubber ring on the left side of the limiting ring is in close contact with the outer surface of the air duct.

[0012] Preferably, the positioning component includes a positioning bolt penetrating the upper and lower surfaces of the snap ring and positioning holes formed on the upper and lower surfaces inside the mounting ring. A fixing plate is fixedly provided at one end of the positioning bolt inside the snap ring, and a sleeve spring is fixedly provided between the fixing plate and the inner surface of the snap ring.

[0013] Preferably, when the sleeve spring is in its naturally extended state, the positioning pin extends out of the outer surface of the snap ring, and the diameter of the positioning pin is the same as that of the positioning hole.

[0014] Preferably, when the positioning bolt is embedded in the positioning hole, the snap ring is tightly attached to the sealing rubber ring on the right side of the limiting ring.

[0015] Preferably, a cleaning component is installed at the right end of the inverted funnel-shaped screen. The cleaning component includes a handle and a scraper. The handle is rotatably mounted on the center of the right side surface of the inverted funnel-shaped screen via a bearing, and the scraper is fixedly mounted on the handle.

[0016] Preferably, the scraper is attached to the outer surface of the inverted funnel-shaped screen.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] 1. This utility model features a sealing rubber ring. When the mounting ring is installed on the duct, the sealing rubber ring on the left side of the limiting ring is tightly attached to the right end of the duct, ensuring the seal between the mounting ring and the duct. When the snap-fit ​​ring on the funnel-shaped screen is snapped into the mounting ring, the snap-fit ​​ring is tightly attached to the sealing rubber ring on the right end of the limiting ring, ensuring the seal when the funnel-shaped screen is installed on the mounting ring. This ensures that the air entering the duct is filtered by the funnel-shaped screen before entering the duct, preventing impurities in the air from entering the duct and improving the quality of the packaged mullite production.

[0019] 2. This utility model, by providing an installation component, allows for easy installation of the mounting ring onto the duct. First, the inverted funnel-shaped screen is installed on the mounting ring, and the positioning component positions the screen. Then, the two inverted L-shaped slots on the mounting ring are aligned with the positioning post and pressed inwards. The positioning post embeds into the inverted L-shaped slot, pressing the trapezoidal block into the insertion groove. The spring is compressed until the positioning post is at the end of the inverted L-shaped slot. The spring force then ejects the trapezoidal block from the insertion groove, causing the mounting ring to rotate. The positioning post then embeds into the bend of the inverted L-shaped slot, completing the installation of the mounting ring. The operation is simple and convenient. To disassemble the mounting ring, simply rotate the mounting ring, and the positioning post will push the trapezoidal block into the insertion groove. At this point, the positioning post is at the inner opening of the inverted L-shaped slot. Pulling the mounting ring outwards will then disassemble the mounting ring. Installation and disassembly are simple and convenient.

[0020] 3. When installing the inverted funnel-shaped screen onto the mounting ring, first pull the fixing plate. The fixing plate moves the positioning bolt towards the center of the locking ring, preventing the positioning bolt from protruding from the outer surface of the locking ring. The sleeve spring is in a stretched state. Then, align the locking ring with the mounting ring and insert the locking ring into the right end of the mounting ring. Rotate the locking ring so that the positioning bolt aligns with the positioning hole on the mounting ring. The elastic force of the sleeve spring causes the positioning bolt 402 to embed into the positioning hole, thus completing the installation. The installation is simple and convenient. When it is necessary to disassemble the inverted funnel-shaped screen 4, the fixing plate moves the positioning bolt towards the center of the locking ring, causing the positioning bolt to disengage from the positioning hole. Then, pull the inverted funnel-shaped screen to the right, causing the locking ring to disengage from the right end of the mounting ring. The disassembly of the inverted funnel-shaped screen is simple and convenient.

[0021] 4. This utility model is equipped with a cleaning component. When there is a lot of dust and impurities on the outer surface of the inverted funnel-shaped screen and it needs to be cleaned, the handle is turned. The handle drives the scraper to rotate, and the scraper scrapes the outer surface of the inverted funnel-shaped screen to clean it, thus preventing the screen from clogging and ensuring that air can pass through it normally.

[0032] Example:

[0033] like Figures 1-7As shown, an embodiment of this utility model provides an air duct for mullite production, including an air duct 2 installed on the housing 1 of a mullite production equipment. An installation ring 3 is installed on the right end of the air duct 2 via an installation component. An inverted funnel-shaped screen 4 is snapped onto the right side of the installation ring 3. A snap-fit ​​ring 401 is fixedly provided on the left side of the inverted funnel-shaped screen 4. Positioning components for positioning the snap-fit ​​ring 401 are provided on the snap-fit ​​ring 401 and the installation ring 3. A limit ring 5 is fixedly provided inside the installation ring 3. Sealing rubber rings 6 are fixedly provided on both sides of the limit ring 5.

[0034] With the sealing rubber ring 6 installed, when the mounting ring 3 is installed on the air duct 2, the sealing rubber ring 6 on the left side of the limiting ring 5 is tightly attached to the right end of the air duct 2, ensuring the sealing between the mounting ring 3 and the air duct 2. When the snap ring 401 on the inverted funnel-shaped screen 4 is snapped into the mounting ring 3, the snap ring 401 is tightly attached to the sealing rubber ring 6 on the right end of the limiting ring 5, ensuring the sealing of the inverted funnel-shaped screen 4 when it is installed on the mounting ring 3. This ensures that the air entering the air duct 2 is filtered by the inverted funnel-shaped screen 4 before entering the air duct 2, preventing impurities in the air from entering the air duct 2 and ensuring the quality of the packaging mullite production.

[0035] In this embodiment, the installation component includes a positioning post 201 fixed on the upper and lower surfaces of the right end of the air duct 2 and an inverted L-shaped slot 301 opened above and below the installation ring 3. An embedding groove 3013 is opened on the inner side of the inverted L-shaped slot 301. A spring 3012 is fixedly installed on the inner side of the embedding groove 3013, and a trapezoidal block 3011 is fixedly installed on the other end of the spring 3012.

[0036] In this embodiment, the width of the inverted L-shaped slot 301 is equal to the diameter of the positioning post 201, which facilitates the positioning post 201 to be engaged in the inverted L-shaped slot 301.

[0037] In this embodiment, the trapezoidal block 3011 is in the shape of a right trapezoid, and when the spring 3012 is in the naturally extended state, the trapezoidal block 3011 is completely embedded in the embedding groove 3013 at the end facing the opening of the inverted L-shaped slot 301. When the spring 3012 is in the maximum compressed state, the trapezoidal block 3011 is completely embedded in the embedding groove 3013, which makes it convenient for the trapezoidal block 3011 to push the positioning post 201 into the bend of the inverted L-shaped slot 301.

[0038] In this embodiment, when the positioning post 201 is engaged with the bent part of the inverted L-shaped slot 301, the sealing rubber ring 6 on the left side of the limiting ring 5 is tightly attached to the outer surface of the air duct 2, ensuring the sealing performance when the mounting ring 3 is installed on the air duct 2.

[0039] With the installation components in place, when installing the mounting ring 3 onto the duct 2, firstly, the inverted funnel-shaped screen 4 is installed onto the mounting ring 3, and the inverted funnel-shaped screen 4 is positioned using the positioning components. Then, the two inverted L-shaped slots 301 on the mounting ring 3 are aligned with the positioning post 201 and pressed inwards, so that the positioning post 201 is embedded in the inverted L-shaped slot 301. The trapezoidal block 3011 is then pressed into the embedding groove 3013, and the spring 3012 is compressed until the positioning post 201 is at the end of the inverted L-shaped slot 301. The elastic force of 12 ejects the trapezoidal block 3011 from the embedded groove 3013, causing the mounting ring 3 to rotate. The positioning post 201 is then embedded in the bend of the inverted L-shaped slot 301, thus completing the installation of the mounting ring 3. The operation is simple and convenient. When disassembling the mounting ring 3, simply rotate the mounting ring 3, and the positioning post 201 will push the trapezoidal block 3011 into the embedded groove 3013. At this time, the positioning post 201 is located at the inner end opening of the inverted L-shaped slot 301. Pulling the mounting ring 3 outward will disassemble the mounting ring 3. The installation and disassembly are simple and convenient.

[0040] In this embodiment, the positioning component includes a positioning bolt 402 that penetrates the upper and lower surfaces of the snap ring 401 and a positioning hole 302 that is opened on the upper and lower surfaces inside the mounting ring 3. A fixing plate 403 is fixedly provided at one end of the positioning bolt 402 inside the snap ring 401, and a sleeve spring 404 is fixedly provided between the fixing plate 403 and the inner surface of the snap ring 401.

[0041] In this embodiment, when the sleeve spring 404 is in its naturally extended state, the positioning pin 402 extends out of the outer surface of the snap ring 401, and the positioning pin 402 has the same diameter as the positioning hole 302, which facilitates the positioning pin 402 to be embedded in the positioning hole 302 and to position the snap ring 401.

[0042] In this embodiment, when the positioning bolt 402 is embedded in the positioning hole 302, the snap ring 401 is tightly attached to the sealing rubber ring 6 on the right side of the limiting ring 5, ensuring the sealing of the connection between the snap ring 401 and the mounting ring 3.

[0043] When installing the inverted funnel-shaped screen 4 onto the mounting ring 3, first pull the fixing plate 403. The fixing plate 403 drives the positioning pin 402 to move towards the center of the locking ring 401, so that the positioning pin 402 will not protrude from the outer surface of the locking ring 401, and the sleeve spring 404 is in a stretched state. Then, align the locking ring 401 with the mounting ring 3 and insert the locking ring 401 into the right end of the mounting ring 3. Rotate the locking ring 401 so that the positioning pin 402 is aligned with the positioning hole 302 on the mounting ring 3, and then... The spring force of the spring 404 causes the positioning bolt 402 to embed into the positioning hole 302, thus completing the installation. The installation is simple and convenient. When it is necessary to disassemble the inverted funnel-shaped screen 4, the fixing plate 403 drives the positioning bolt 402 to move towards the center of the locking ring 401, so that the positioning bolt 402 is disengaged from the positioning hole 302. Then, the inverted funnel-shaped screen 4 is pulled to the right, so that the locking ring 401 is disengaged from the right end of the mounting ring 3. The disassembly of the inverted funnel-shaped screen 4 is simple and convenient.

[0044] In this embodiment, a cleaning component is installed at the right end of the inverted funnel-shaped screen 4. The cleaning component includes a handle 7 and a scraper 701. The handle 7 is rotatably mounted on the center of the right side surface of the inverted funnel-shaped screen 4 via a bearing, and the scraper 701 is fixedly mounted on the handle 7.

[0045] In this embodiment, the scraper 701 is attached to the outer surface of the inverted funnel-shaped screen 4, which facilitates the scraper 701 to clean the outer surface of the inverted funnel-shaped screen 4.

[0046] By incorporating a cleaning component, when a large amount of dust and impurities adhere to the outer surface of the inverted funnel-shaped screen 4 and require cleaning, the handle 7 is rotated, causing the scraper 701 to rotate. The scraper 701 then cleans the outer surface of the inverted funnel-shaped screen 4, achieving the cleaning effect and preventing the screen from becoming clogged, thus ensuring that air can pass through the screen normally.

[0047] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
