Description

Technical Field

[0001] This utility model relates to the field of feeding equipment, and in particular to a dust-free powder feeding device for use in a reaction vessel. Background Technology

[0002] For dust-free feeding of powder materials into reactors, there are specially designed devices that can add powder and granular materials into the reactors in a dust-free and precise manner. These devices achieve dust-free feeding of powder materials, effectively solving the problems of dust pollution and inaccurate feeding, and improving production efficiency and product quality.

[0003] A negative pressure environment is created by compressed air or a vacuum pump, and the negative pressure difference is used to draw materials into the machine. The materials are then transported to the reactor through pipelines. This method ensures that no dust is generated during the material transport process, achieving dust-free feeding. However, when dust enters the machine, it needs to be screened to help the material be evenly distributed inside the machine, avoiding material accumulation and blockage, thereby improving the material transport efficiency and feeding accuracy. However, for existing screen plates, which are generally stably set in the feeding chamber, the continuous feeding of dust will lead to poor material flowability, thereby reducing the efficiency of screening and feeding. Therefore, a dust-free powder feeding device for reactors is proposed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a dust-free powder feeding device for use in reactors. By incorporating an inclined guide slot within the connecting frame, the outer positioning frame can enter through the feed chamber opening, completing the installation of the screen plate and placing it in a sloping state. When material enters, the sloping design allows for smoother flow under gravity and vibration, while also increasing the surface area, thus reducing material accumulation and clogging on the screen plate and improving screening efficiency. This design also facilitates the removal of the screen plate for easier subsequent cleaning.

[0005] In order to solve the above-mentioned technical problems, the present invention solves the problem that the material flowability is poor when the dust-free feeding equipment for powder applied to the reactor is continuously fed in through the following technical solution.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A dust-free powder feeding device for use in a reactor includes a feeding chamber, a screen plate, and a conveying structure mounted on the feeding machine body. The feeding chamber and the conveying structure are connected by a connecting frame with a guide slot. An outer positioning frame is connected to the outer periphery of the screen plate and can be inserted into the guide slot.

[0008] Preferably, the front end of the outer positioning frame is connected to a front baffle, which is located inside the feed chamber door.

[0009] Preferably, the inner end face of the front baffle is curved, and the lower part of the outer end face is flat.

[0010] Preferably, a limiting protrusion is connected to the outer positioning frame, and the limiting protrusion can fit against the inner wall of the connecting frame.

[0011] Preferably, a handle groove is provided on the flat part of the front baffle.

[0012] Preferably, a stabilizing inner pad is adhesively bonded to the inner wall of the handle groove.

[0013] Preferably, the stabilizing inner pad is made of rubber and has an uneven surface.

[0014] Preferably, the screen plate is provided with a push plate for pushing, and a hydraulic mechanism is provided between the front baffle and the push plate, with one end of the hydraulic rod of the hydraulic mechanism connected to the push plate.

[0015] Preferably, the hydraulic mechanism has an assembly block at the end away from the push plate, and the front baffle has an internal groove through which the assembly block passes and is connected by bolts.

[0016] Preferably, the bottom of the pusher plate is evenly provided with multiple pushing blocks, which can move within the screen of the screen plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The dust-free powder feeding device for reactors provided in this application features an inclined guide slot within the connecting frame, allowing the outer positioning frame to enter along the feed chamber opening and complete the installation of the screen plate, placing it in a sloping state. When material enters, the sloping design enables the material to flow more smoothly under the influence of gravity and vibration, and also increases the surface area, thereby reducing material accumulation and clogging on the screen plate, thus improving screening efficiency. This design also facilitates the removal of the screen plate for easier subsequent cleaning.

[0019] This application sets up a front baffle, which is fixedly installed at the front of the outer positioning frame. When the outer positioning frame is inserted into the guide slot, the screen plate is restricted to the feeding part inside the feeding chamber door.

[0020] This application sets a limiting protrusion plate, which is installed on the upper surface of the outer positioning frame and can make close contact with the inner wall of the connecting frame, thereby restricting the screen plate set on the inner circumference of the outer positioning frame to the outside of the guide slot and improving the sealing effect at the connection.

[0021] This application incorporates a pusher plate located in the middle of the feeding chamber. The pusher plate can move back and forth along the upper surface of the screen plate, thus ensuring uniformity of material feeding by pushing the material during the feeding process.

Example

[0034] Please see Figure 1 - Figure 6 A dust-free powder feeding device for use in a reactor includes a feeding chamber 101, a screen plate 102 and a conveying structure 103 installed on the feeding machine body 1. The feeding chamber 101 and the conveying structure 103 are provided with a connecting frame 2 with a guide slot 3. The screen plate 102 is connected to an outer positioning frame 4 and can be inserted into the guide slot 3.

[0035] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The dust-free powder feeding equipment for a reactor of this application mainly consists of a feeding body 1, a feeding chamber 101, a screen plate 102, and a conveying structure 103. To improve material flowability, the screen plate 102 is designed to allow for screening when the material enters the conveying structure 103 from the feeding chamber 101. A connecting frame 2 is provided at the connection between the feeding chamber 101 and the conveying structure 103. The connecting frame 2 has a certain height, allowing for a certain period of dwell time when the material enters the conveying structure 103 from the feeding chamber 101. A front baffle 5 is fixedly installed on the outer periphery of the screen plate 102. One end of the connecting frame 2 has an inclined guide slot 3, which allows the outer positioning frame 4 to enter along the opening of the feed chamber 101 until the outer positioning frame 4 is fully inserted into the guide slot 3, thus completing the overall installation of the screen plate 102. This results in a sloped state during installation. When materials enter, the sloped design allows the materials to flow more smoothly under the action of gravity and vibration, and also increases the area, thereby reducing the accumulation and blockage of materials on the screen plate, thus improving screening efficiency. At the same time, this design allows the screen plate 102 to be pulled out for internal cleaning in a timely manner, bringing convenience to the application.

[0036] This application also includes a front baffle 5, which is fixedly installed at the front of the outer positioning frame 4. When the outer positioning frame 4 is inserted into the guide slot 3, the screen plate 102 is restricted to the feeding part inside the feeding chamber 101. Thus, during feeding, the material can be guided from the screen plate 102 to the top of the screen plate 102. After being screened by the screen plate 102, the material is compressed by the vacuum pump and enters the conveying structure 103 under negative pressure. It is then guided to the reactor by the connection of the pipeline. The thickness of the front baffle 5 is set higher than that of the conveying structure 103 and the outer positioning frame 4, which can block the material to a certain extent when it enters. The inner end face of the front baffle 5 is provided with an arc for guiding.

[0037] This application also includes a handle groove 501 and a stabilizing inner pad 502. The lower part of the outer end face of the front baffle 5 is flat, and the handle groove 501 is provided in the middle of the flat part to facilitate pulling out the screen plate 102 as a whole. The upper and lower end faces of the inner wall of the handle groove 501 are symmetrically glued with the stabilizing inner pad 502. The stabilizing inner pad 502 is made of rubber. The side that contacts the hand during the pull is uneven, which can further increase the friction of the contact surface during the pull, making the movement more stable.

[0038] This application also includes a limiting protrusion 401, which is installed on the upper surface of the outer positioning frame 4. When the outer positioning frame 4 is inserted into the guide slot 3, it can make close contact with the inner wall of the connecting frame 2, thereby restricting the screen plate 102 set on the inner circumference of the outer positioning frame 4 to the outside of the guide slot 3, improving the sealing effect at the connection, and limiting the outer positioning frame 4 as a whole.

[0039] This application also includes a pusher plate 6, which is located in the middle of the feeding chamber 101 and can move back and forth along the upper surface of the screen plate 102. Therefore, during the feeding process, the material can be pushed to ensure the uniformity of the material feeding and prevent clogging.

[0040] This application also includes a hydraulic mechanism 7, which is located between the push plate 6 and the front baffle 5. The hydraulic mechanism 7 is a hydraulic telescopic rod, and one end of the hydraulic rod is connected to the push plate 6. When started, it can drive the push plate 6 to move back and forth on the screen plate 102, so that the material on the screen plate 102 is continuously pushed during the continuous feeding process, thereby ensuring the effect of use.

[0041] This application also includes a built-in groove 503 and an assembly block 8. The assembly block 8 is installed on the hydraulic mechanism 7. The built-in groove 503 is located on one side of the front baffle 5. After one end of the hydraulic rod of the hydraulic mechanism 7 is connected to the push plate 6, the end with the assembly block 8 can pass through the inside of the built-in groove 503. After passing through, it is fastened to the front baffle 5 with bolts, thereby performing the overall installation operation of the hydraulic mechanism 7.

[0042] This application also includes a pusher block 601, of which several are evenly installed at the bottom of the pusher plate 6. When the pusher plate 6 can move along the upper surface of the screen plate 102, the pusher block 601 can simultaneously move within the screen of the screen plate 102, thereby further allowing the material to flow and ensuring the overall application effect of the pusher plate 6.

[0043] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
