Description

Technical Field

[0001] The invention relates to the field of raw material screening, in particular to a closed raw material screening machine. Background Art

[0002] New materials refer to structural materials with excellent performance and functional materials with special properties that have been recently developed or are being developed. Structural materials mainly utilize their mechanical properties such as strength, toughness, hardness, elasticity, etc., such as new ceramic materials, amorphous alloys (metallic glass), etc. Functional materials mainly utilize their electrical, optical, acoustic, magnetic, thermal and other functions and physical effects. In recent years, the new materials studied and developed in the world mainly include new metal materials, fine ceramics and optical fibers, etc. Before the processing and production of new materials, the raw materials of new materials need to be screened, so that raw materials of different specifications can be used for the production of different products. The existing screening devices have the following defects in actual use: Most of the existing screening devices are open-air vibration screening, which is greatly affected by external environmental factors, resulting in the flying of materials or bursting everywhere, causing certain harm to the sanitation of the processing environment, and the flying of materials may cause users to inhale, causing harm to the health of users.

[0003] Moreover, among the current sealed screening equipment, most of them only screen the raw materials in two properties and cannot be refined, or simply screen the powder and granules. The granules need to be screened again later, which is time-consuming and labor-intensive. Summary of the invention

[0004] The object of the present invention is to provide a closed raw material screening machine in order to solve the above-mentioned problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A closed raw material screening machine comprises a sealing mechanism for sealing and collecting, and a central filtering mechanism and a particle filtering mechanism for separating raw materials, wherein the central filtering mechanism is installed at the center of the sealing mechanism, the particle filtering mechanism is arranged around the outside of the central filtering mechanism, and the particle filtering mechanism is powered by a power mechanism outside;

[0007] The central filtering mechanism includes a central cylinder, a particle filter screen is installed on the upper end of the central cylinder, a guide plate is installed on the outer side of the upper end of the particle filter screen, and a plurality of discs composed of particle filtering mechanisms are evenly arranged on the outer side of the central cylinder. The particle filtering mechanism includes a centrifugal box with a fan-shaped structure, a bottom filter screen is fixed to the bottom of the centrifugal box, a traction rod is installed on the side of the bottom filter screen corresponding to the central cylinder, and the traction rod corresponds to the limiting groove formed on the central cylinder.

[0008] Preferably, the guide plate encloses an umbrella-shaped structure.

[0009] With such arrangement, when the material is poured into the sealing cylinder through the feed cylinder, the vacuum collection tank provides negative pressure to suck the powdered raw materials, and the collection effect of the powdered materials is improved with the assistance of the guide plate.

[0010] Preferably, the traction rod is fixedly connected to the bottom filter screen, and the bottom filter screen is slidably connected to the centrifugal box.

[0011] With such arrangement, the traction rod is fixedly connected to the bottom filter screen, and when the traction rod passes through the oscillation section of the limiting groove, the vibration can be transmitted to the bottom filter screen, so that the small raw materials are vibrated and filtered into the first collection tank.

[0012] Preferably, the internal structure of the oscillating section on the limiting groove is an arc-shaped wave line, and the lifting section of the limiting groove is a parabolic structure outside the central tube.

[0013] With such arrangement, the oscillating section provides vibration to the bottom filter screen to assist in filtering small raw materials, and the lifting section lifts the centrifugal box, thereby opening the side panel and allowing large raw materials to fall out into the second collection tank.

[0014] Preferably: the sealing mechanism includes a sealing cylinder and a feeding cylinder, the feeding cylinder is installed on the upper end of the sealing cylinder, a first collecting tank is installed inside the sealing cylinder corresponding to the oscillation section of the limiting groove, a second collecting tank is installed inside the sealing cylinder corresponding to the lifting section of the limiting groove, and a vacuum collecting tank is connected to the bottom of the center cylinder.

[0015] Such an arrangement makes it convenient to separate and collect different raw materials.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In a confined space, materials in different states are quickly separated through independent structures. At the same time, the limiting grooves and centrifugal force are used to ensure the separation effect of the materials and improve the efficiency of material screening and storage.

[0032] Example 1

[0033] like Figure 1-Figure 8 As shown, a closed raw material screening machine includes a sealing mechanism 1 for sealing and collecting, and a central filtering mechanism 3 and a particle filtering mechanism 4 for separating raw materials. The central filtering mechanism 3 is installed at the center of the sealing mechanism 1, and the particle filtering mechanism 4 is arranged around the outside of the central filtering mechanism 3. The particle filtering mechanism 4 is powered by a power mechanism 2.

[0034] The central filtering mechanism 3 includes a central cylinder 31, a particle filter screen 32 is installed on the upper end of the central cylinder 31, a guide plate 33 is installed on the outer side of the upper end of the particle filter screen 32, and a plurality of discs composed of particle filtering mechanisms 4 are evenly arranged on the outer side of the central cylinder 31. The particle filtering mechanism 4 includes a centrifugal box 41 with a fan-shaped structure, a bottom filter screen 42 is fixed to the bottom of the centrifugal box 41, a traction rod 45 is installed on the side of the bottom filter screen 42 corresponding to the central cylinder 31, and the traction rod 45 corresponds to the limiting groove 44 formed on the central cylinder 31. A side plate 43 is installed on the side of the centrifugal box 41 away from the traction rod 45 through a pin shaft, and the outside of the side plate 43 is connected to the ring gear 22 of the power mechanism 2, and the limiting groove 44 is divided into an oscillation section and a lifting section.

[0035] Preferably: the guide plate 33 is enclosed in an umbrella-shaped structure. When the material is poured into the sealing cylinder 11 through the feed cylinder 12, the vacuum collection tank 14 provides negative pressure to suck the powdered raw material, and the collection effect of the powdered material is improved with the assistance of the guide plate 33; the traction rod 45 is fixedly connected to the bottom filter screen 42, and the bottom filter screen 42 is slidably connected to the centrifugal box 41. The traction rod 45 is fixedly connected to the bottom filter screen 42. When the traction rod 45 passes through the oscillation section of the limiting groove 44, the vibration can be transmitted to the bottom filter screen 42, so that the small raw materials are vibrated and filtered into the first collection tank 13. The internal structure of the oscillation section on the limiting groove 44 is an arc-shaped wavy line. The lifting section of the positioning groove 44 presents a parabolic structure outside the central tube 31; the oscillation section provides vibration for the bottom filter screen 42 to assist in filtering small raw materials, and the lifting section lifts the centrifugal box 41, thereby opening the side plate 43, allowing large raw materials to fall into the second collecting tank 15; the sealing mechanism 1 includes a sealing cylinder 11 and a feeding cylinder 12, and the feeding cylinder 12 is installed on the upper end of the sealing cylinder 11, and a first collecting tank 13 is installed at the position of the oscillation section of the limiting groove 44 inside the sealing cylinder 11, and a second collecting tank 15 is installed at the position of the lifting section of the limiting groove 44 inside the sealing cylinder 11, and a vacuum collecting tank 14 is connected to the bottom of the central tube 31 to facilitate the separation and collection of different raw materials.

[0036] Working principle: Pour the raw materials into the sealing cylinder 11 through the feeding cylinder 12, start the motor 21 and the vacuum collecting tank 14, at this time, the mixed raw materials are first subjected to the negative pressure of the vacuum collecting tank 14 inside the sealing cylinder 11, and then the powdered raw materials are sucked into the vacuum collecting tank 14, and at the same time, the particles are mixed and fall into the centrifugal box 41 corresponding to the oscillation section of the limiting groove 44. At this time, the traction rod 45 is pulled and vibrated by the oscillation section of the limiting groove 44, and the particle raw materials inside the centrifugal box 41 are vibrated. At this time, the small particles of raw materials are subjected to the bottom filter 42. The particles are shaken and fall into the first collecting tank 13, and the motor 21 and the ring gear 22 continue to drive the particle filtering mechanism 4 to rotate. When the bottom filter screen 42 reaches the lifting section of the limiting groove 44, the traction rod 45 pulls the bottom filter screen 42 and the centrifugal box 41 to tilt, and at the same time, the ring gear 22 limits the side plate 43, and the side plate 43 is opened. Because the centrifugal box 41 is also subjected to the centrifugal force provided by the motor 21, the large particles are thrown out and fall into the second collecting tank 15. At this time, the screening of the materials of different properties is completed.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
