Description

Technical Field

[0001] This utility model relates to the field of air classifier technology, specifically to a delay structure for a heavy-duty air classifier. Background Technology

[0002] In modern industrial production, the fine sorting of materials is crucial for improving product quality and increasing resource utilization. As a device that sorts materials using the principles of aerodynamics, the air classifier has been widely used in many fields due to its advantages such as high efficiency, environmental friendliness, and strong adaptability.

[0003] In order to prevent internal material from overflowing, existing delay structures usually use filters to intercept materials. However, the filters and the main body of the air classifier are often connected by complex methods such as bolt fastening and snap-fit. The installation structure is compact, but disassembly requires specific tools, which is cumbersome and consumes a lot of manpower and time. Utility Model Content

[0004] The purpose of this invention is to provide a delayed structure for a heavy-duty air classifier to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a delay structure for a heavy-duty air classifier, comprising a heavy-duty air classifier body, and further comprising:

[0006] The first material plate and the second material plate are placed inside the heavy-duty air separator body;

[0007] A clamping assembly is placed inside the heavy-duty air classifier body. The clamping assembly includes a rotating disk movably connected inside the heavy-duty air classifier body, a rotating column connected to the rotating disk, a guide plate connected to the rotating column, a sliding rod movably connected to the guide plate, and a clamping rod connected to the sliding rod.

[0008] Furthermore, blades are connected to the rotating disk, a filter plate is movably connected to the clamping rod, an extension shell is movably connected to the filter plate, the extension shell is fixedly connected to the heavy-duty air classifier body, an air supply pipe is fixedly connected to the side of the extension shell away from the heavy-duty air classifier body, an air pump is fixedly connected to the air supply pipe on the extension shell, the air pump on the extension shell is installed at the bottom of the heavy-duty air classifier body, and a limit groove is formed on the side of the extension shell near the heavy-duty air classifier body.

[0009] The above technical solution is adopted: by setting up an air pump, when the air pump is started, air is drawn into the body of the weight-forming air separator through the air supply pipe. The air pump has high controllability and can better control the airflow speed inside the body of the weight-forming air separator.

[0010] Furthermore, a rubber block connects the first material plate and the second material plate.

[0011] The above technical solution involves setting rubber blocks to seal the gap between the first and second material plates. During feeding, the material will not fall directly onto the second material plate, but will instead pass through the initial screening of the first material plate.

[0012] Furthermore, the rubber block between the first material plate and the second material plate is connected to the side of the first material plate and the second material plate away from the rotating disk.

[0013] The above technical solution is adopted: by setting a rubber block between the first material plate and the second material plate, the second material plate and the side of the second material plate away from the rotating disk, that is, the feed inlet of the weight-type air classifier body, are blocked to prevent the material from falling directly onto the second material plate.

[0014] Furthermore, ventilation holes are provided on both the guide plate and the rotating disk, and the rotating column is movably connected to the extension shell.

[0015] The above technical solution is adopted: ventilation holes are provided on both the guide plate and the rotating disk, and the rotating column is supported and the weighted air separator body is sealed during use.

[0016] Furthermore, the rotating disk has an arc-shaped hole, and the sliding rod is movably connected to the arc-shaped hole on the rotating disk.

[0017] The above technical solution is adopted: by opening an arc-shaped hole on the rotating disk, it is convenient to use the arc-shaped hole to drive the sliding rod during use.

[0018] Furthermore, the bottom of the heavy-duty air separator body is provided with an opening.

[0019] Using the above technical solution: When in use, the staff can select a suitable-sized container according to actual needs and fix it to the bottom of the heavy-duty air separator body with bolts.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, an airflow-driven transmission method is used to achieve convenient fixing and disassembly of the filter screen. After the air pump is started, the generated airflow drives the rotating disk to rotate, and the rotating column on the rotating disk moves accordingly, thereby driving the guide plate to rotate. When the guide plate rotates, it drives the sliding rod to move under the limiting action, thereby causing the clamping rod to stick tightly to the extension shell and slide on the limiting groove, clamping the filter screen. The greater the wind speed, the greater the clamping force, ensuring that the filter screen is stable and does not fall off during operation. When the filter screen needs to be replaced, the air pump is stopped, and the extension shell can be easily disassembled without the need for special tools to deal with the complex connection structure, which greatly improves the efficiency of filter screen replacement and reduces labor and time costs.

[0031] 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.

[0032] Example:

[0033] like Figures 1-6 As shown, this utility model provides a technical solution: a delay structure for a heavy-duty air classifier, including a heavy-duty air classifier body 1, and further comprising:

[0034] The first material plate 11 and the second material plate 12 are fixedly connected inside the heavy-duty air separator body 1;

[0035] Clamping assembly 2 is placed inside the heavy-duty air classifier body 1. The clamping assembly 2 includes a rotating disk 22 rotatably connected inside the heavy-duty air classifier body 1, a rotating column 23 fixedly connected to the rotating disk 22, a guide plate 21 fixedly connected to the rotating column 23, a sliding rod 24 slidably connected to the guide plate 21, and a clamping rod 25 fixedly connected to the sliding rod 24.

[0036] In this invention, an airflow-driven transmission method is used to achieve convenient fixing and disassembly of the filter screen. After the air pump is started, the generated airflow drives the rotating disk 22 to rotate, and the rotating column 23 on the rotating disk 22 moves accordingly, thereby driving the guide plate 21 to rotate. When the guide plate 21 rotates, it drives the sliding rod 24 to move under the limiting action, thereby causing the clamping rod 25 to press tightly against the extension shell 27 and slide on the limiting groove, clamping the filter screen. The greater the airflow speed, the greater the clamping force, ensuring that the filter screen is stable and does not fall off during operation. When the filter screen needs to be replaced, the air pump is stopped, and the extension shell 27 can be easily disassembled without the need for special tools to handle complex connection structures, greatly improving the efficiency of filter screen replacement and reducing labor and time costs.

[0037] Furthermore, such as Figures 1 to 6 As shown, blades are fixedly connected to the rotating disk 22, and a filter plate 26 is slidably connected to the clamping rod 25. An extension shell 27 is slidably connected to the filter plate 26. The extension shell 27 is fixedly connected to the heavy-duty air separator body 1. An air supply pipe is fixedly connected to the side of the extension shell 27 away from the heavy-duty air separator body 1. An air pump is fixedly connected to the air supply pipe on the extension shell 27. The air pump on the extension shell 27 is installed at the bottom of the heavy-duty air separator body 1. A limiting groove is opened on the side of the extension shell 27 near the heavy-duty air separator body 1. By setting up an air pump, when the air pump is started, air is drawn into the heavy-duty air separator body through the air supply pipe. It has high controllability and can adjust the airflow speed inside the air separator. According to the characteristics of different materials and the sorting requirements, the operator can flexibly adjust the power of the air pump to create a suitable airflow environment inside the equipment and ensure that the material sorting process is efficient and stable.

[0038] like Figure 3As shown, a rubber block is fixedly connected between the first material plate 11 and the second material plate 12. By setting the rubber block, the gap between the first material plate 11 and the second material plate 12 can be effectively sealed. During the feeding process, this design can prevent the material from falling directly into the second material plate 12, forcing the material to pass through the first material plate 11 for preliminary screening first, so that large particles are separated first, laying the foundation for subsequent fine sorting and improving the overall sorting accuracy.

[0039] The rubber block between the first material plate 11 and the second material plate 12 is fixedly connected to the side of the first material plate 11 and the second material plate 12 away from the rotating disk 22. The rubber block is located at the feed inlet of the weight-type air classifier body. This layout further strengthens the control of the feeding path. Through physical isolation, it prevents materials from directly entering the second material plate 12 without being screened by the first material plate 11, ensuring the standardization and orderliness of the material sorting process.

[0040] like Figures 3 to 6 As shown, ventilation holes are provided on both the guide plate 21 and the rotating disk 22. The rotating column 23 is rotatably connected to the extension shell 27. In actual use, the ventilation holes on the guide plate 21 and the rotating disk 22 can provide stable support for the rotating column 23 and ensure the reliable operation of the transmission structure of the clamping assembly 2. On the other hand, they can effectively seal the air separator body, prevent air leakage, maintain the integrity of the internal airflow field of the equipment, and ensure that the sorting effect is not affected.

[0041] like Figures 3 to 6 As shown, the rotating disk 22 has an arc-shaped hole, and the sliding rod 24 is slidably connected in the arc-shaped hole on the rotating disk 22. The arc-shaped hole on the rotating disk 22 provides a guide for the transmission of the sliding rod 24. During the operation of the equipment, the rotation of the rotating disk 22 transmits the motion to the sliding rod 24 through the arc-shaped hole, so that the sliding rod 24 can move according to a predetermined trajectory, thereby driving the clamping rod 25 to move, realizing the stable clamping and loosening of the filter screen, and ensuring the transmission accuracy and stability of the clamping assembly 2.

[0042] Working principle:

[0043] like Figures 1 to 6 As shown, when in use, the staff will unscrew the extension shell 27 that is bolted to the heavy-duty air classifier body 1, and initially attach the filter plate 26 to the filter plate 26 with tape. The staff will then select a suitable storage container according to actual needs and fix it to the bottom of the heavy-duty air classifier body 1 with bolts.

[0044] When the heavy-duty air classifier body 1 is in normal use, the air pump will continuously draw gas out of the heavy-duty air classifier body 1, so that the material first flows on the first material plate 11. The larger material particles will fall through the through holes on the first material plate 11 and fall into the second material plate 12. At this time, the airflow continues to flow, and the smaller and lighter materials among the materials that fall on the second material plate 12 flow further, while the larger materials fall directly onto the collection container.

[0045] At the same time, the airflow causes the rotating disk 22 to rotate, which in turn causes the rotating column 23 to rotate the guide plate 21. The clamping rod 25 is pressed against the extension shell 27 and slides on the limiting groove on the extension shell 27. At this time, the sliding rod 24 is driven to move under the limiting action of the guide plate 21, so that the clamping rod 25 clamps the filter screen. The higher the wind speed, the tighter the filter screen is clamped. At this time, the filter screen is not easy to fall off. When there are many small materials adsorbed on the filter screen, the staff can stop the air pump and disassemble the extension shell 27 to collect the materials. The materials need to pass through the rotating disk 22 and the guide plate 21 to completely detach from the first material plate 11 and the second material plate 12, which plays a delaying role and allows the materials to be separated better.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
