Description

Technical Field

[0001] The utility model relates to a crushed material receiver and belongs to the technical field of plastic particle processing. Background Art

[0002] Plastic pellets are a raw material widely used in the production of plastic products. The production and processing technology for plastic pellets has advanced rapidly, making them an integral part of modern life. Dust removal is essential during the production process, but existing equipment suffers from inefficiencies and clogging. A search revealed that Chinese patent publication number CN209618293 discloses a material receiver. In this patent, a suction fan is activated to evacuate the valve body and the material receiving tank in preparation for receiving the material. The valve body feed cylinder drives the valve body feed port sealing plate to retract, opening the valve body feed port, and the mixed material enters the valve body through this port. When the valve body discharge cylinder that does not need feeding is actuated, the mixed material in the valve body closes the corresponding valve body discharge port, and then opens other discharge ports, allowing the material to flow out through the opened discharge ports and enter the material receiving tank. After the material enters the material receiving tank from the bottom feed port, it flows out through the umbrella-shaped discharge hopper and swirls upward under the action of the suction fan to prevent the material from sinking due to gravity and causing secondary stratification. At the same time, the material entering the material receiving tank from multiple feed ports at the top generates a swirl in the tank body under the action of the swirl plate, further preventing the material from sinking due to gravity and causing secondary stratification. However, in this patent, when the suction fan generates swirl distribution, the material may be sucked into the inlet of the suction fan, causing blockage and affecting the efficiency of the equipment.

[0026] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0027] like Figure 1-6 As shown, a crushed material receiver includes:

[0028] The barrel body 1 is provided with a first working chamber 11, and the barrel body 1 is further provided with a suction port 12 and a discharge port 13. The suction port 12 is provided on the barrel body 1, and the discharge port 13 is provided at the bottom of the barrel body 1. The suction port 12 is communicated with the first working chamber 11;

[0029] The upper cover 2 is mounted on the top of the barrel 1 and is provided with a second working chamber 21. The second working chamber 21 is connected to the first working chamber 11. A filter 3 is provided between the second working chamber 21 and the first working chamber 11. The filter 3 is suitable for preventing the crushed material in the first working chamber 11 from entering the second working chamber 21.

[0030] The back-blowing device is connected to the upper cover 2 and is suitable for blowing the filter screen 3 to make the broken materials stuck on the filter screen 3 fall off.

[0031] In this embodiment, the crushed materials are plastic particles, but may also be other tiny objects.

[0032] Specifically, if Figure 1-3 As shown, a barrel hoop 22 is provided between the upper cover 2 and the barrel body 1 , and the barrel hoop 22 is suitable for fixing the upper cover 2 to the barrel body 1 .

[0033] In this embodiment, a handle is further provided on the barrel hoop 22. The handle is suitable for loosening the barrel hoop 22 when opened, so that the upper cover 2 can be taken down for easy disassembly. The handle is suitable for tightening the barrel hoop 22 when locked, thereby fixing the upper cover 2 on the barrel body 1.

[0034] Specifically, if Figure 1-4 As shown, the back-blowing device includes a right-angle pulse valve 41 and an air storage tank 42. The right-angle pulse valve 41 is connected to the upper cover body 2, and the air storage tank 42 is connected to the right-angle pulse valve 41. The right-angle pulse valve 41 is suitable for controlling the flow rate of the sprayed gas. The right-angle pulse valve 41 is an existing technology, and its structure and implementation principle are not repeated in this embodiment.

[0035] Specifically, if Figure 1-3 As shown, a crushed material receiver also includes a vacuum shut-off valve 5, which is installed on the upper cover 2 and is connected to the second working chamber 21. The vacuum shut-off valve 5 is suitable for evacuating the air in the first working chamber 11 and the second working chamber 21 to generate negative pressure to suck in the crushed material.

[0036] In this embodiment, the vacuum shut-off valve 5 is adapted to cooperate with external equipment to suck the crushed material into the first working chamber 11 .

[0037] Specifically, if Figure 6As shown, a crushed material receiver also includes a stirring assembly, which includes a first cylinder 61, a connecting rod 62 and two arch-breaking rods 63. The first cylinder 61 is installed on the filter 3, the connecting rod 62 is connected to the first cylinder 61, and the arch-breaking rod 63 is installed on the connecting rod 62. The first cylinder 61 is suitable for driving the arch-breaking rod 63 to move back and forth up and down.

[0038] In this embodiment, arch-breaking parts are provided at both ends of the arch-breaking rod 63, and the two arch-breaking parts extend in opposite directions. This setting can effectively break up the accumulated crushed materials and roll them over, so that the back-blowing device can fully blow the crushed materials in the first working chamber 11, thereby improving the dust removal effect.

[0039] Specifically, if Figure 4-5 As shown, the backflush device further includes a guide tube 43 , which is disposed in the second working chamber 21 . The guide tube 43 is connected to the right-angle pulse valve 41 , and is provided with a plurality of guide holes 431 facing the first working chamber 11 .

[0040] Specifically, if Figure 4 As shown, a conical surface 7 suitable for the flow of crushed materials is provided between the first working chamber 11 and the discharge port 13 .

[0041] Specifically, if Figure 4 As shown, the discharge port 13 is provided with a switch cover device, which includes a cover plate 81 and a magnetic ring 82. The cover plate 81 is hinged at the discharge port 13, and the magnetic ring 82 is connected to the cover plate 81. The cover plate 81 is suitable for opening and closing at the discharge port 13.

[0042] Specifically, if Figure 2 As shown, the switch cover device also includes a magnetic sensor 9, which is installed on the outside of the barrel body 1. The cover plate 81 is suitable for rotating into position so that the magnetic ring 82 is opposite to the magnetic sensor 9. The magnetic sensor 9 is suitable for sending a signal to the external controller after sensing the magnetic ring 82, and the external controller starts sucking the material after receiving the signal.

[0043] In this embodiment, the magnetic sensor 6 is suitable for sensing the magnetic field of the magnetic ring 82. When the cover plate 81 is pushed open by material, the cover plate 81 rotates downward along the hinge point, and the magnetic ring 82 rotates upward along the hinge point. At this time, the magnetic ring 82 is away from the sensing range of the magnetic sensor 9. At this time, the equipment is in a full material state, and the external controller controls the corresponding equipment to stop sucking material.

[0044] When the crushed material is exhausted, the magnetic ring 82 rotates downward along the hinge point due to its own gravity. At this time, the magnetic ring 82 is close to the sensing range of the magnetic sensor 9. At this time, the equipment is in a material-out state, and the external controller controls the corresponding equipment to start sucking the material.

[0045] In this embodiment, the vacuum shut-off valve 5 is opened, and the gas in the first working chamber 11 and the second working chamber 21 is evacuated to generate negative pressure, and the external equipment is cooperated to allow the crushed material to enter the first working chamber 11 through the suction port 12. After entering the first working chamber 11, the crushed material falls to the discharge port 13, and the falling crushed material pushes open the cover plate 81. At this time, the angle between the cover plate 81 and the discharge port 13 is large, and the cover plate 81 drives the magnetic ring 82 to rotate. The magnetic ring 82 is away from the magnetic sensor 9. The magnetic sensor 9 does not sense the magnetic ring 82 and sends a signal to the external controller. The external controller closes the vacuum shut-off valve 5 to stop suctioning. When all the crushed material in the first working chamber 11 falls out, the cover plate 81 swings back to the discharge port 13 due to the gravity of the magnetic ring 82. At this time, the angle between the cover plate 81 and the discharge port 13 is small, and the magnetic sensor 9 senses the magnetic ring 82 and sends a signal to the external controller to open the vacuum shut-off valve 5 to start a new round of suctioning.

[0046] When the cover plate 81 is pushed open by the falling crushed materials, the magnetic sensor 9 will send a signal to the external controller if it does not sense the magnetic ring 82. The external controller will control the back-blowing device to start, and the gas in the gas tank 42 will be blown toward the filter 3 through the guide hole 431 on the guide tube 43, so that the crushed materials on the filter 3 will break away from the falling and flow out from the discharge port 13.

[0047] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
