Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screen equipment, and more particularly to a vibrating screen with an anti-leakage structure. Background Art

[0002] Vibrating screens can screen and sort materials. The screen is equipped with a mesh that vibrates to screen the material on the mesh. Small-diameter materials fall below the mesh and are discharged from the outlet below the vibrating screen, while large-diameter materials remain on the mesh, achieving screening and sorting. Vibrating screens are usually equipped with multiple outlets for discharging the screened material through different pipes.

[0003] Since the vibrating screen is in a vibrating state during operation, the discharge port is usually not directly connected to the storage device. There are usually two ways to connect the material. The first is to place the storage device at the bottom of the discharge pipe and discharge the material directly into the storage device. However, this method is prone to material leakage. The second method is to stick a hose or storage bag on the discharge pipe, but this method may cause material leakage due to the tape not being firmly adhered or falling off during vibration. Moreover, the tape marks are difficult to clean after use. Some equipment will provide a fixed structure at the discharge pipe for installing and fixing the connected storage bag. For example, the Chinese patent with application number 202121797782.8 discloses a circular vibrating screen discharge structure, which includes a discharge pipe arranged on the machine body, a material receiving bag is sleeved on the discharge pipe, a connecting tube is provided on the discharge pipe, and a mounting tube is detachably connected to the connecting tube; a positioning ring is provided on the mounting tube, and a positioning groove for the positioning ring to be inserted is provided on the connecting tube; the opening part of the material receiving bag passes through the interior of the positioning ring and covers the outer peripheral side of the positioning ring. The circular vibrating screen discharge structure achieves the clamping of the receiving bag through the cooperation of multiple cylinders, so that the material will not leak out of the receiving bag and the discharge pipe. However, when in use, the receiving bag needs to pass through the inside of the bag support tube and open at the top, and components such as the optical axis and the cylinder are arranged on the outside of the clamping flange. When operating on the receiving bag inside the flange, it will be blocked by the optical axis and the cylinder, which will increase the difficulty of operation. At the same time, the cooperation of multiple cylinders is required for clamping the receiving bag, which increases the complexity. In addition, when replacing the receiving bag, the equipment will shake to varying degrees, which will cause the remaining material in the equipment to leak out during the gap between the receiving bag replacement, resulting in material waste and environmental pollution.

[0004] Therefore, it is necessary to propose a vibrating screen with an anti-leakage structure to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-4A vibrating screen with a leak-proof structure includes a vibrating screen body 101 and a discharge pipe 102. The discharge pipe 102 is connected to other storage devices for conveying screened materials. The vibrating screen body 101 is provided with a plurality of discharge pipes 103. The discharge pipes 102 are sleeved on the discharge pipes 103. The bottom of the discharge pipe 103 is connected to a fixing frame 104. The fixing frame 104 is connected to the discharge pipe 103 of the vibrating screen body 101 for connecting to the discharge pipe 102.

[0028] When installing the discharge pipe 102 and the vibrating screen body 101, powder leakage may occur at the connection. At the same time, the connection between the discharge pipe 102 and the vibrating screen body 101 is too complicated and cannot be quickly disassembled. The following provides a structure that can avoid dust leakage and can be quickly disassembled: Figure 2 and Figure 3 , the discharge pipe 102 includes a mounting sleeve 105, which is sleeved on the fixing frame 104, and the inner circumferential array of the mounting sleeve 105 has a first cavity 106, and the two ends of the first cavity 106 are connected to the inner annular surface and the outer annular surface of the mounting sleeve 105, and a moving block 107 and a spring 108 are provided in the first cavity 106. The spring 108 pushes the moving block 107 out of the outer annular surface of the mounting sleeve 105 by stretching, and the moving tube 112 can come into contact with the moving block 107 during the upward movement, thereby squeezing the moving block 107 back into the first cavity 106. When the moving block 107 returns to the first cavity 106, it will drive the internal clamping block 111 to move toward the fixing frame 104, thereby being stuck in the annular groove 109 to complete the installation of the mounting sleeve 105 and the fixing frame 104, and the spring 108 pushes the moving block 107 to move toward the outer annular surface of the mounting sleeve 105;

[0029] refer to Figure 3, an annular groove 109 is provided on the outer wall of the fixing frame 104, and a second cavity 110 is provided inside the moving block 107. A clamping block 111 and a spring 108 are provided in the second cavity 110. The spring 108 pushes the clamping block 111 out of the second cavity 110 so that it can be inserted into the annular groove 109. The spring 108 pushes the clamping block 111 to be located in the annular groove 109. Specifically, when installing the discharge pipe 102 and the installation sleeve 105, the moving pipe 112 is held and moved upward. At this time, the moving pipe 112 will move the moving pipe 112 upward. The block 107 is pressed back into the first cavity 106, and the clamping block 111 extends from the inner annular surface of the installation sleeve 105. When it comes into contact with the bottom of the fixing frame 104, it is pressed back into the second cavity 110 through the inclined surface. When the clamping block 111 moves to a position at the same height as the annular groove 109, it is inserted into the annular groove 109, thereby fixing the installation sleeve 105 on the fixing frame 104. At this time, the top of the installation sleeve 105 also comes into contact with the fixing frame 104 and squeezes the sealing rubber ring 113, thereby improving the sealing effect.

[0030] refer to Figure 2 and Figure 3 A moving tube 112 slides up and down on the outer ring surface of the mounting sleeve 105. When the moving tube 112 moves to the top, it squeezes the moving block 107. When it moves to the bottom, the squeezing effect on the moving block 107 is released. One side of the moving block 107 is provided with an inclined surface that contacts the inner ring surface of the moving tube 112. The bottom of the moving tube 112 is connected to a spring 108.

[0031] Specifically, the bottom of the fixing frame 104 and the top of the block 111 are provided with inclined surfaces for sliding contact. When the block 111 comes into contact with the bottom of the fixing frame 104 , the inclined surfaces can facilitate squeezing the block 111 back into the second cavity 110 .

[0032] Specifically, refer to Figure 2 and Figure 3 The top outer ring surface of the fixing frame 104 and the top of the mounting sleeve 105 are provided with mutually matching inclined surfaces. A sealing rubber ring 113 is connected to the top inclined surface of the mounting sleeve 105. When the mounting sleeve 105 moves to contact the fixing frame 104, it will squeeze the sealing rubber ring 113 in the middle, thereby improving the sealing of the connection.

[0033] When the discharge pipe 102 is replaced, the remaining material may flow out of the discharge pipe 103, causing material waste and environmental pollution. The following provides a structure that can prevent the material from flowing out of the discharge pipe 103 when the discharge pipe 102 is replaced: Figure 2 and Figure 4Specifically, the center of the discharge pipe 103 is connected to a first guide rod 114 for sliding up and down connection, the bottom of the first guide rod 114 is connected to a cover plate 115, the top of the first guide rod 114 is connected to a connecting plate 116, and the other end of the connecting plate 116 is connected to a second guide rod 117. The first guide rod 114 and the second guide rod 117 are arranged in parallel, and the second guide rod 117 passes through the side wall of the discharge pipe 103, and the bottom of the second guide rod 117 is in contact with the mounting sleeve 105.

[0034] refer to Figure 2 and Figure 4 When the mounting sleeve 105 contacts the fixing frame 104, the top of the mounting sleeve 105 will contact the second guide rod 117, causing it to move upward. The second guide rod 117 drives the first guide rod 114 to move upward through the connecting plate 116, thereby driving the cover plate 115 to move upward, opening the discharge port of the discharge pipe 103 so that the material can pass through. When the mounting sleeve 105 is removed from the fixing frame 104, the second guide rod 117 loses the support of the mounting sleeve 105, thereby driving the cover plate 115 to cover the discharge port of the discharge pipe 103 to prevent the material from leaking.

[0035] Specifically, refer to Figure 3 and Figure 4 Symmetrical strip plates 118 are provided on the side walls of the second guide rod 117 and the discharge pipe 103, and springs 108 are connected between the symmetrical strip plates 118. The springs 108 pull the second guide rod 117 downward. The springs 108 located between the fixed frame 104 and the second guide rod 117 are used to drive the second guide rod 117 to move downward.

[0036] Specifically, refer to Figure 2 The discharge pipe 102 also includes a telescopic tube 119. The vibrating screen body 101 will be in a vibrating state when in use. The telescopic tube 119 can effectively prevent the vibration from being transmitted to other equipment. The telescopic tube 119 is connected to the bottom of the mounting sleeve 105.

[0037] In this embodiment, when replacing the discharge pipe 102, the moving tube 112 is pulled downward. At this time, the spring 108 pushes the moving block 107 to extend from the outer ring of the mounting sleeve 105. The clamping block 111 inside the moving block 107 is pulled out from the annular groove 109. At this time, the mounting sleeve 105 can be removed from the fixing frame 104. At this time, the cover plate 115 will fall, thereby blocking the discharge port of the discharge pipe 103 to prevent material from leaking out.

[0038] When installing the installation sleeve 105, hold the movable tube 112 and put the installation sleeve 105 on the fixed frame 104. When the block 111 is inserted into the annular groove 109, the installation of the installation sleeve 105 and the fixed frame 104 is completed. At this time, the cover plate 115 is lifted to allow the material to flow smoothly.

[0039] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
