Description

Technical Field

[0001] The utility model relates to the field of material pipe sealing, in particular to a material feed pipe blocking device. Background Art

[0002] The discharge pipe is a conveying device that can transport materials in the unloading station to the pit. After the unloading is completed, backwind often occurs. When backwind occurs, the wind will blow directly from the discharge pipe into the unloading station, causing dust to float in the unloading station. To avoid this situation, the discharge port of the discharge pipe needs to be blocked when there is no material.

[0003] The existing plugging method usually uses a manual gate valve or an electric gate valve to open and close. Since the unloading is uninterrupted, it is usually necessary to frequently open and close the valve. When a manual gate valve is used, the operator needs to open and close the manual gate valve continuously, which will increase the labor intensity of the operator. When an electric gate valve is used, frequent opening and closing will cause malfunctions, which will directly increase the economic cost of the enterprise. At the same time, these methods may also have poor sealing in the open and closed state for a long time, resulting in a slight backwind phenomenon. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0022] like Figure 1 As shown, a feeding pipe sealing device includes a feeding port arranged at the lower part of the feeding pipe 1, a sealing cavity 2 is connected and fixed at the feeding port of the feeding pipe 1, a rotating shaft 3 is supported and fixed inside the sealing cavity 2, and both ends of the rotating shaft 3 are respectively connected to rebound components 8, and the first sealing plate 9 and the second sealing plate 91 are respectively connected to the left and right sides of the corresponding rebound component 8.

[0023] like Figure 2 , 3As shown, the rebound component 8 includes a connecting plate 11, and symmetrical arc-shaped grooves 14 are respectively opened on the two end surfaces of the connecting plate 11, and sliders 13 are arranged in the corresponding arc-shaped grooves 14. The corresponding sliders 13 are respectively connected and fixed to the corresponding first turntable 10 and the second turntable 12, and a tension spring 15 is arranged between the corresponding arc-shaped grooves 14 and the sliders 13.

[0024] like Figure 3 As shown, one end of the tension spring 15 is connected and fixed to the arc-shaped sliding groove 14 and the other end is connected and fixed to the sliding block 13 .

[0025] like Figure 1 , 2 As shown in FIGS. 3 and 4 , the first turntable 10 and the second turntable 12 rotate in opposite directions.

[0026] like Figure 1 As shown, the connecting disk 11 is fixedly connected to the rotating shaft 3 , and the first rotating disk 10 and the second rotating disk 12 are rotationally connected to the rotating shaft 3 .

[0027] like Figure 2 , 3 As shown in FIG. 4 , the arc-shaped slide groove 14 is arranged concentrically with the first rotating disk 10 , the second rotating disk 12 and the connecting disk 11 .

[0028] like Figure 1 As shown, a limiting plate 5 connected and fixed to the side wall is arranged inside the blocking cavity 2, a plurality of electromagnets 4 are arranged at the lower part of the limiting plate 5, and a sealing strip is arranged at the lower part of the limiting plate 5.

[0029] like Figure 1 As shown, a photoelectric switch 7 is arranged in the blocking cavity 2 , and a protective cover 6 is arranged on the upper part of the photoelectric switch 7 .

[0030] like Figure 1 As shown, a control system is also included, and the control system includes a controller 16, and the controller 16 is electrically connected to the electromagnet 4 and the photoelectric switch 7 respectively.

[0031] The implementation principle of a feed pipe plugging device in the embodiment of the present application is as follows:

[0032] When there is no falling material in the feeding tube 1, the first blocking plate 9 and the second blocking plate 91 are not affected by gravity, and the tension spring 15 is in a retracted state. The rebound component 8 will keep the first blocking plate 9 and the second blocking plate 91 in a horizontal state. At the same time, the photoelectric switch 7 will send a passage signal to the controller 16, and the controller 16 will send a signal to the electromagnet 4 to power it. The electromagnet 4 will be tightly attracted with the first blocking plate 9 and the second blocking plate 91 to prevent the occurrence of reverse wind;

[0033] When there is material falling in the feeding pipe 1, the signal of the photoelectric switch 7 will be blocked, and a circuit breaker signal will be sent to the controller 16. At the same time, the controller 16 sends a signal to cut off the power of the electromagnet 4. At this time, the electromagnet 4 has no suction with the first blocking plate 9 and the second blocking plate 91;

[0034] When the falling material falls on the first sealing plate 9 and the second sealing plate 91, due to the influence of weight, the first sealing plate 9 and the second sealing plate 91 will be turned down with the rotating shaft 3 as the center. When the first sealing plate 9 and the second sealing plate 91 are turned down, the first turntable 10 and the second turntable 12 correspondingly connected to the first sealing plate 9 and the second sealing plate 91 will also rotate by a corresponding angle. At the same time, the sliders 13 on the first turntable 10 and the second turntable 12 will also slide in the corresponding arc-shaped slide grooves 14, and at the same time, the tension spring 15 will be stretched to generate a rebound force. At this time, the falling material will be transported from the space generated by the first sealing plate 9 and the second sealing plate 91 and the sealing cavity 2 after turning down to the pit set outside;

[0035] When the material is conveyed, the first blocking plate 9 and the second blocking plate 91 are not affected by the gravity of the material, and are pulled back to a horizontal state by the resilience generated by the tension spring 15. At the same time, the photoelectric switch 7 is turned on, and a passage signal is sent to the controller 16. The controller 16 sends a signal to power the electromagnet 4. The electromagnet 4 generates suction to tightly engage with the first blocking plate 9 and the second blocking plate 91 to prevent backwind.

[0036] Thereby completing the entire plugging process, the entire process saves time and effort, reduces the labor intensity of operators, prevents electric valves from malfunctioning due to frequent opening and closing, and better reduces unnecessary economic expenditures for the enterprise.
