Description

Technical Field

[0001] This utility model relates to a cyclone separator for the synthesis and processing of high-performance PPS resin for aerospace applications, belonging to the field of PPS resin technology. Background Technology

[0002] PPS is a resin with advantages such as being hard and brittle, having high crystallinity, being flame retardant, having good thermal stability, high mechanical strength, and excellent electrical properties. It has excellent thermal stability, wear resistance, creep resistance, and excellent mechanical and electrical properties over a wide range (temperature, humidity, frequency). It also has a low dielectric charge and low dielectric loss. Cyclone separators are required when processing PPS resin.

[0003] Chinese Patent Publication No. (CN 211756057 U) discloses a cyclone separator for PPS resin processing, including a separator shell, a dust hopper installed at the bottom of the separator shell, and an air outlet pipe connected to the top of the separator shell. A feed pipe is installed on one side of the separator shell, and a controller is fixed below the feed pipe on one side of the separator shell. A purification box is installed at the end of the air outlet pipe away from the separator shell, and an exhaust pipe is connected to the side of the purification box away from the air outlet pipe. A drain valve is installed at the bottom of the purification box, and a water tank is fixed at the top of the purification box. This invention, through the cooperation of a water pump, a water tank, a water supply pipe, an atomizing nozzle, and a purification box, allows dust in the air to combine with water to form water droplets that fall to the bottom of the purification box, thereby effectively treating the dust, preventing it from leaking to the outside and causing harm, and improving the safety factor of the device.

[0004] The above-mentioned device prevents resin from sticking to the inner wall of the separator shell by heating. However, in actual use, the temperature may cause dust to explode, resulting in low safety of the equipment and potentially causing significant property damage. In addition, when the resin falls into the ash hopper, it may accumulate and cause blockage, thus affecting normal material discharge.

[0005] To address this, a cyclone separator for the synthesis and processing of high-performance PPS resin for aerospace applications is proposed. Utility Model Content

[0006] In view of this, the present invention provides a cyclone separator for high-performance PPS resin synthesis and processing in aerospace, to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0007] The technical solution of this utility model is implemented as follows: A cyclone separator for high-performance PPS resin synthesis and processing in aerospace applications includes a separator housing. A feed pipe is connected to the left side of the separator housing, and an air outlet pipe is connected to the top of the separator housing. A dust hopper is provided at the bottom of the separator housing. A cleaning assembly is provided in the inner cavity of the separator housing. The cleaning assembly includes a shell, which is fixedly installed in the inner cavity of the separator housing. A drive motor is fixedly installed at the top of the inner cavity of the shell. A driving bevel gear is fixedly connected to the output end of the drive motor. A connecting rod is fixedly installed at the bottom of the driving bevel gear. Screw blades are fixedly installed on the surface of the connecting rod. A driven bevel gear is movably connected to the bottom of the inner cavity of the shell. A hollow tube is fixedly installed at the bottom of the driven bevel gear. The connecting rod passes through the inner side of the driven bevel gear and the inner cavity of the hollow tube. Fixed rods are fixedly installed on the surface of the hollow tube, and scrapers are fixedly installed on the outer side of the fixed rods.

[0008] More preferably, a transmission bevel gear is movably connected to the left side of the inner cavity of the housing, and the surface of the transmission bevel gear meshes with the surfaces of both the driving bevel gear and the driven bevel gear.

[0009] More preferably, the number of scrapers is three, and the three scrapers are arranged at equal intervals in the circumferential direction.

[0010] More preferably, the outer side of the scraper is arc-shaped, and the outer side of the scraper is attached to the inner wall of the separator housing.

[0011] More preferably, the hollow tube and the connecting rod are oriented in the same direction, and the hollow tube and the connecting rod rotate in opposite directions.

[0012] More preferably, the surface of the separator housing is threaded with mounting bolts, and the bottom of the mounting bolts is threaded to the inner surface of the ash hopper.

[0013] More preferably, a flange is fixedly installed at the end of the feed pipe away from the separator housing, and bolt holes are provided on the surface of the flange.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. This utility model, by setting up a cleaning component, can cause the active and driven bevel gears to rotate through the output of the drive motor. This allows the scraper to scrape off the resin adhering to the inner wall of the separator housing, while the auger blades can guide the resin. This effectively avoids the situation where some resin cannot be discharged normally due to adhesion, or resin accumulation that cannot be properly arranged. It ensures the stability and convenience of normal resin discharge and makes it convenient for operators to use.

[0016] Second, by setting installation bolts, the ash hopper can be disassembled and assembled, which facilitates the disassembly of the ash hopper and the pouring of the resin after the resin has separated from the dust and entered the ash hopper. By setting bolt holes, external feeding equipment can be connected, which improves the stability of the feed pipe connection.

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-4 As shown, this utility model embodiment provides a cyclone separator for high-performance PPS resin synthesis and processing in aerospace applications. It includes a separator housing 1, a feed pipe 4 connected to the left side of the separator housing 1, an exhaust pipe 3 connected to the top of the separator housing 1, a dust hopper 5 at the bottom of the separator housing 1, and a cleaning assembly 2 within the inner cavity of the separator housing 1. The cleaning assembly 2 includes a housing 201, which is fixedly installed within the inner cavity of the separator housing 1. A drive motor 202 is fixedly installed at the top of the inner cavity of the housing 201. A driving bevel gear 203 is fixedly connected to the output end of the drive motor 202. A connecting rod 204 is fixedly installed at the bottom of the driving bevel gear 203. A screw conveyor blade 205 is fixedly installed on the surface of the connecting rod 204. A driven bevel gear 206 is movably connected to the bottom of the inner cavity of the housing 201. A hollow tube 207 is fixedly installed at the bottom of the driven bevel gear 206. A connecting rod 204 passes through the inner side of the driven bevel gear 206 and the inner cavity of the hollow tube 207. A fixing rod 208 is fixedly installed on the surface of the hollow tube 207. A scraper 209 is fixedly installed on the outer side of the fixing rod 208. A transmission bevel gear 210 is movably connected to the left side of the inner cavity of the outer shell 201. The surface of the transmission bevel gear 210 meshes with the surfaces of the driving bevel gear 203 and the driven bevel gear 206. There are three scrapers 209, which are equidistantly arranged in the circumferential direction. The outer side of the scraper 209 is arc-shaped and fits against the inner wall of the separator housing 1. The hollow tube 207 and the connecting rod 204 are oriented in the same direction, and the rotation directions of the hollow tube 207 and the connecting rod 204 are opposite.

[0029] By setting up the cleaning component 2, the output of the drive motor 202 can cause the active bevel gear 203 and the driven bevel gear 206 to rotate, thereby causing the scraper 209 to scrape off the resin adhering to the inner wall of the separator housing 1. The auger blades 205 can guide the resin, effectively preventing some resin from being unable to be discharged normally due to adhesion, and preventing resin from accumulating and being unable to be arranged normally. This ensures the stability and convenience of normal resin discharge and makes it convenient for operators to use.

[0030] Example 2

[0031] like Figure 1-5 As shown, in one embodiment, the surface of the separator housing 1 is threaded with mounting bolts 6, the bottom of the mounting bolts 6 is threaded to the inner surface of the ash hopper 5, and a flange 7 is fixedly installed at the end of the feed pipe 4 away from the separator housing 1, and bolt holes 8 are opened on the surface of the flange 7.

[0032] By setting the mounting bolts 6, the ash hopper 5 can be disassembled and assembled, making it easy to disassemble the ash hopper 5 and pour out the resin after the resin has separated from the dust and entered the ash hopper 5. By setting the bolt holes 8, external feeding equipment can be connected, which improves the stability of the feed pipe 4 connection.

[0033] In operation, this invention works as follows: First, material is injected into the separator housing 1 through the feed pipe 4. As the separator housing 1 operates, air is blown from bottom to top onto the resin, while dust is discharged through the air outlet pipe 3. The resin falls downward into the ash hopper 5. At this time, the output of the drive motor 202 drives the active bevel gear 203 to rotate. The active bevel gear 203 synchronously drives the connecting rod 204 and the auger blade 205 to rotate, thus guiding the material. When the active bevel gear 203 rotates, it cooperates with the transmission bevel gear 210. The transmission bevel gear 210 drives the driven bevel gear 206 to rotate. The driven bevel gear 206 synchronously drives the hollow tube 207, the fixed rod 208, and the scraper 209 to rotate. At this time, the scraper 209 moves in the circumferential direction and scrapes off the resin adhering to the inner wall of the separator housing 1, so that the adhering resin falls normally into the ash hopper 5.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
