Description

Technical Field

[0001] The utility model relates to the technical field of cyclone separators, in particular to a compressed air spraying device. Background Art

[0002] In the industrial production process, the cyclone separator is a commonly used solid-liquid or solid-gas separation equipment, which is widely used in chemical, pharmaceutical, food processing and other fields. Its working principle is mainly to separate the solid particles in the mixture from the air flow or liquid flow through centrifugal force. However, during the long-term operation of the cyclone separator, its inner wall and discharge port are prone to accumulate residues. If these residues are not cleaned in time, it will not only affect the separation efficiency of the cyclone separator, but may even cause blockage, thus affecting the normal operation of the entire production line.

[0003] To solve this problem, the traditional cleaning method is usually to shut down the machine regularly for manual cleaning, but this method is not only time-consuming and labor-intensive, but also affects production efficiency. Therefore, it is particularly important to develop a device that can automatically clean the cyclone separator residue online. Utility Model Content

[0004] The utility model aims to provide a compressed air blowing device to solve the problem that the traditional cleaning method proposed in the above background technology usually requires regular shutdown for manual cleaning, but this method is not only time-consuming and labor-intensive, but also affects production efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides a compressed air blowing device, including an annular tube, which is divided into an upper annular tube and a lower annular tube, and the upper annular tube and the lower annular tube are respectively installed on the outside of the cyclone separator discharge port, and the outsides of the upper annular tube and the lower annular tube are connected to an air inlet pipe, and an inner annular tube is arranged inside the cyclone separator discharge port, and a plurality of connecting tubes are distributed on the outer wall of the inner annular tube, one end of the connecting tube is connected to the inner annular tube, and the other end passes through the outer wall of the cyclone separator and is connected to the annular tube, and a plurality of blowing tubes are arranged on the lower surface of the inner annular tube.

[0006] Preferably, the upper annular tube is located above the lower annular tube, and the diameter of the upper annular tube is greater than the diameter of the lower annular tube.

[0007] Preferably, a valve is installed on the air intake pipe, and the outer end of the air intake pipe is externally connected to a compressed air pump.

[0008] Preferably, the inner annular tube is attached to the inner wall of the cyclone separator.

[0009] Preferably, the connecting pipes are arranged in a circular shape at equal intervals outside the inner ring pipe.

[0010] Preferably, the blowing pipes are arranged in a circular shape with equal intervals on the surface of the inner ring tube.

[0012] Preferably, the blowing port of the blowing pipe faces the inner wall of the lower discharge port of the cyclone separator.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the compressed air spraying device, the device can cover the entire outer side of the discharge port of the cyclone separator through the arrangement of the upper annular tube and the lower annular tube, ensuring the comprehensiveness of the spraying range. The design of the double annular tube not only increases the spraying area, but also improves the uniformity of the spraying, thereby more effectively removing the residue. The layout of the inner annular tube and the connecting pipe enables the compressed air to evenly and forcefully impact the inner wall and the discharge port of the cyclone separator, further improving the cleaning effect. In particular, the annular equidistant distribution of the spraying tube ensures that the entire inner wall can obtain uniform spraying force, avoiding cleaning dead corners. The spiral guide structure design inside the spraying tube not only enhances the rotation force of the spraying airflow, but also can more effectively peel off the residue from the inner wall of the cyclone separator. This innovative design greatly improves the efficiency and thoroughness of cleaning. The device can achieve seamless docking with the cyclone separator without affecting the normal operation of the cyclone separator, realizes online automatic cleaning, and avoids the tediousness and inefficiency of regular shutdown for manual cleaning. This not only improves production efficiency, but also reduces labor costs and equipment downtime, bringing significant economic benefits to the enterprise. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a compressed air blowing device, such as Figure 1-Figure 3 As shown, it includes an annular tube, which is divided into an upper annular tube 1 and a lower annular tube 2. The upper annular tube 1 and the lower annular tube 2 are respectively installed on the outside of the discharge port of the cyclone separator 3. The outer sides of the upper annular tube 1 and the lower annular tube 2 are connected with an air inlet pipe 4. The inner annular tube 11 is arranged inside the discharge port of the cyclone separator 3. A plurality of pipes 12 are distributed on the outer wall of the inner annular tube 11. One end of the pipe 12 is connected to the inner annular tube 11, and the other end passes through the outer wall of the cyclone separator 3 and is connected to the annular tube. A plurality of blowing pipes 13 are arranged on the lower surface of the inner annular tube 11. The inner wall of the discharge port of the cyclone separator 3 is sprayed to peel off the residue from the inner wall of the cyclone separator. The upper annular tube 1 and the lower annular tube 2 have the same structure and can both realize the blowing of the inner wall of the discharge port.

[0022] In this embodiment, the upper annular tube 1 is located above the lower annular tube 2, and the diameter of the upper annular tube 1 is larger than that of the lower annular tube 2, so as to facilitate the blowing operation at different positions.

[0023] Specifically, a valve 5 is installed on the air inlet pipe 4, and the outer ends of the air inlet pipe 4 are connected to an external compressed air pump to facilitate the introduction of compressed gas.

[0024] Furthermore, the inner ring tube 11 is attached to the inner wall of the cyclone separator 3 to ensure the blowing operation on the inner wall.

[0025] Furthermore, the connecting pipes 12 are arranged in a circular shape at equal intervals outside the inner ring pipe 11 to ensure uniform delivery of the gas.

[0026] Furthermore, the blowing pipes 13 are arranged in a circular shape at equal intervals on the surface of the inner ring tube 11 to ensure uniform gas ejection.

[0027] Furthermore, the blowing pipe 13 is a circular tube structure, and the inner wall is rotatably connected to a spiral guide structure 132 through a bearing 131, so that the spiral guide structure 132 is driven to rotate when the compressed gas is blown out. The spiral guide structure can rotate when the compressed gas is blown out. This rotational motion can increase the turbulence of the airflow and make the airflow more evenly distributed at the blowing port, thereby improving the uniformity and effect of the blowing.

[0028] Furthermore, the blowing port of the blowing pipe 13 faces the inner wall of the lower discharge port of the cyclone separator 3, so as to smoothly blow the material on the inner wall off.

[0029] When the compressed air blowing device of the utility model is used, the external compressed air pump is first started to generate high-pressure compressed gas. The valve 5 on the air inlet pipe 4 is opened to allow the compressed gas to flow into the upper annular pipe 1 and the lower annular pipe 2 through the air inlet pipe 4. Since the diameter of the upper annular pipe 1 is larger than that of the lower annular pipe 2, this design is convenient for adapting to the blowing needs of different positions. The gas flows evenly from the annular pipes (the upper annular pipe 1 and the lower annular pipe 2) through the connecting pipes 12 (these connecting pipes are distributed in annular shapes and equal spacing outside the inner annular pipe 11). The inner annular pipe 11 fits tightly on the inner wall of the cyclone separator 3 to ensure accurate blowing of the inner wall. The gas then enters the blowing pipe 13 (these blowing pipes are also distributed in annular shapes and equal spacing on the surface of the inner annular pipe 11) and is ejected from the blowing port. In particular, each blowing pipe 13 is equipped with a spiral guide structure 132 connected by a bearing 131. When the compressed gas passes through, it will drive the spiral guide structure to rotate. The rotation of the spiral guide structure 132 increases the turbulence of the airflow, making the airflow ejected from the blowing pipe 13 more uniform. This design significantly improves the uniformity and efficiency of the blowing. The blowing port of the blowing pipe 13 faces the inner wall of the lower discharge port of the cyclone separator 3, ensuring that the residue can be accurately and effectively stripped from the inner wall of the cyclone separator. The stripped residue is then discharged through the discharge port of the cyclone separator 3, thereby completing the entire blowing cleaning process.

[0030] Finally, it should be noted that the electronic components in the cyclone separator 3 in this embodiment are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the field.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
