Description

Technical Field

[0001] The utility model relates to the technical field of double-opening plug-in door structures, in particular to a double-opening plug-in door structure. Background Art

[0002] The plug-in door structure is generally installed at the primary cold air inlet of the coal mill. It is manufactured for use in the primary cold air inlet of the coal mill, the cold air ducts with high wind pressure such as the outlet of the primary fan and the blower, and the flue gas ducts with low wind pressure such as the exhaust fan and the dust collector flue gas inlet and outlet, to cut off the flow of the medium.

[0003] For example, a double-opening gate for anti-clogging pneumatic conveying with the authorization announcement number "CN116142802A" overcomes the following problems of existing gate valves: the gate of the valve is fixedly connected to the output end of the cylinder, which is not convenient to disassemble during later replacement and maintenance, and the gate aperture of the valve is unique in size. Not only can the flow rate passing through not be adjusted according to needs, but it is also easy to cause the air flow rate to slow down due to different flow rates, thereby clogging the valve hole, and further causing the conveying flow rate to decrease during use. However, when using the double-opening gate structure, the inner diameter needs to be replaced after the double-opening gate structure is disassembled as a whole. If the inner diameter of the double-opening gate structure wants to be changed during operation, it is impossible, resulting in the use limitations of the double-opening gate structure, affecting the normal use of the double-opening gate structure. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A double-opening plug-in door structure is designed, including a frame and a protective pad, the front and rear sides of the frame are respectively fixed to the inner side of the protective pad, the inner wall of the frame is connected to a control structure, the outer side of the control structure is connected to a handle, the left and right sides of the frame are respectively connected to a supporting structure, and the front and rear sides of the frame are respectively processed with a plurality of circular openings.

[0007] Preferably, the control structure includes a vertical plate and a door plate, the upper and lower sides of the vertical plate are respectively fixed to the upper and lower sides of the inner wall of the frame, the inner side of the vertical plate is fitted with the outer wall of the door plate, the outer side of the door plate is rotatably connected to a first screw, and the outer side of the first screw is fixed to a circular plate.

[0008] Preferably, the outer wall of the first screw is threadedly connected to the outer wall of the frame.

[0009] Preferably, the outer side of the circular plate is fixedly connected to the inner side of the handle.

[0010] Preferably, the outer side of the vertical plate is fixedly connected to the inner side of the pad.

[0012] The utility model proposes a double-opening plug-in door structure, which has the following beneficial effects: a rotating circular plate in the control structure drives a first screw to rotate outward through a frame, and the rotating first screw drives the door panel to move outward from the inner side of the vertical plate. At this time, the two closed door panels are separated, so that the inside of the frame is opened, and the double opening of the door panel is realized. At this time, the gas in the pipeline can pass through the frame. When the amount of gas passing through is controlled, only the first screw on one side needs to be rotated to control the movement of the door panel, thereby eliminating the use limitations of the double-opening plug-in door structure and ensuring the normal use of the double-opening plug-in door structure.

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Embodiment 1:

[0020] See also Figure 1-4 In the present embodiment, a double-opening plug-in door structure includes a frame 1 and a protective pad 4. The front and rear sides of the frame 1 are respectively fixedly connected to the inner side of the protective pad 4. The protective pad 4 is made of rubber. The inner wall of the frame 1 is connected to a control structure 2. The outer side of the control structure 2 is connected to a handle 5. The left and right sides of the frame 1 are respectively connected to a supporting structure 3. The front and rear sides of the frame 1 are respectively processed with multiple circular openings.

[0021] The control structure 2 includes a vertical plate 201 and a door plate 202. The upper and lower sides of the vertical plate 201 are respectively fixedly connected to the upper and lower sides of the inner wall of the frame 1. The inner side of the vertical plate 201 fits the outer wall of the door plate 202. The outer side of the door plate 202 is rotatably connected to a first screw rod 203. The inner side of the outer wall of the first screw rod 203 is subjected to force to rotate through the outer bearing of the door plate 202. The outer side of the first screw rod 203 is fixedly connected to a circular plate 204. The outer wall of the first screw rod 203 is threadedly connected to the outer wall of the frame 1. The outer side of the circular plate 204 is fixedly connected to the inner side of the handle 5. The handle 5 is convenient for driving the circular plate 204 to rotate. The outer side of the vertical plate 201 is fixedly connected to the inner side of the protective pad 4.

[0022] The rotating circular plate 204 in the control structure 2 drives the first screw 203 to rotate outward through the frame 1, and the rotating first screw 203 drives the door panel 202 to move outward from the inner side of the vertical plate 201. At this time, the two closed door panels 202 are separated, so that the inside of the frame 1 is opened, and the double opening of the door panel is realized. At this time, the gas in the pipeline can pass through the frame. When the amount of gas passing through is controlled, it is only necessary to rotate the first screw 203 on one side to control the movement of the door panel 202, thereby eliminating the use limitations of the double-opening plug-in door structure and ensuring the normal use of the double-opening plug-in door structure.

[0023] The supporting structure 3 includes a bracket 301 and a second screw rod 302. The inner sides of the two brackets 301 are respectively fixed to the lower left and right sides of the frame 1. The inner wall of the bracket 301 is threadedly connected to the outer wall of the second screw rod 302. The second screw rod 302 is subjected to force to rotate up and down through the inner wall of the bracket 301. The bottom of the second screw rod 302 is fixed to a base plate 303.

[0024] Working principle:

[0025] Double-opening door structure installation:

[0026] Select a second screw rod 302 of corresponding length, and gradually screw the second screw rod 302 into the interior of the bracket 301, and then fit the bottom plate 303 with the contact surface, so that the height of the frame 1 is consistent with the height of the external pipe, and then make the spatial position of the vertical plates 201 on the left and right sides of the inner wall of the frame 1 fit with the external pipe, and then pass the bolts through the external pipe connection port and connect it with the circular port of the outer wall of the frame 1 to complete the installation of the double-opening plug-in door structure.

[0027] Double-opening door structure installation and use:

[0028] Hold the handle 5 and rotate it. The handle 5 rotates the circular plate 204. The rotating circular plate 204 rotates outward with the first screw 203 through the frame 1. The rotating first screw 203 moves the door panel 202 from the inner side of the vertical plate 201 to the outer side. At this time, the two closed door panels 202 are separated, so that the inside of the frame 1 is opened, and the double opening of the door panels is realized. At this time, the gas in the pipeline can pass through the frame. When controlling the amount of gas passing through, only the first screw 203 on one side needs to be rotated to control the movement of the door panel 202.

[0029] Embodiment 2:

[0030] See also Figure 1-4 In the present embodiment, a double-opening plug-in door structure further comprises a transverse plate 6, the inner sides of the two transverse plates 6 are respectively fixedly connected to the upper and lower front ends of the frame 1.

[0031] Working principle:

[0032] When the double-opening plug-in door structure cannot support the installation, first make the rear or front of the horizontal plate 6 fit with the connection, then the bolts pass through the horizontal plate 6 and are threadedly fixed to the connection, and then the double-opening plug-in door structure is connected to the external pipeline.
