Description

Technical Field

[0001] The utility model relates to a vibrating screen mesh for limestone and belongs to the technical field of screen meshes. Background Art

[0002] The screen is woven with metal wire or fiber wire, which can remove and recover different types and small suspended solids. Screen separation has the advantages of simplicity, high efficiency and low operating cost. It is generally used for smaller-scale wastewater treatment. There are many kinds of screens, the main two are vibrating screens and hydraulic screens.

[0003] A Chinese public patent (publication number: CN203209308U) discloses a multi-layer vibrating screen, which includes: a first screen plate, a second screen plate and a third screen plate placed overlapping each other, each screen plate surface is distributed with screen holes, the aperture size of the screen holes on the surface of each screen plate gradually decreases from one end of the screen plate to the other end, and the aperture size of the screen holes at the corresponding positions of the first screen plate, the second screen plate and the third screen plate gradually decreases from top to bottom. The multi-layer vibrating screen of the utility model has a simple structure, obvious screening effect, and is easy to clean. While increasing its practical life, it reduces production costs and improves screening efficiency;

[0004] The screen is mainly composed of a mesh screen and an external frame, and the two are usually integrated. The vibrating screen is usually used to screen hard materials. After the screen has been working for a long time, the screen holes on its surface may change in size due to the impact of the material, and may also be blocked by the material. Both will affect the normal screening work. The installation of the vibrating screen is usually fixed to the output end of the vibration motor by welding. Therefore, when the screen needs to be disassembled for maintenance or cleaning, disassembly and installation are relatively cumbersome and time-consuming, which is inconvenient to use.

[0005] For this reason, a vibrating screen mesh for limestone is proposed. Utility Model Content

[0006] In view of this, the utility model provides a vibrating screen for limestone to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0007] The technical solution of the utility model is implemented as follows: a vibrating screen for limestone, comprising an outer frame and a mesh screen, mounting blocks are fixedly mounted on both the front and rear sides of the left side of the mesh screen, and both the front and rear sides of the surfaces of the two mounting blocks are provided with card slots, both the upper and lower sides of the left side of the mesh screen are provided with screw grooves, and both the upper and lower sides of the two mounting blocks are provided with jacks;

[0008] A disassembly mechanism is provided on the inner surface of the left side of the outer frame, and the disassembly mechanism includes a cavity, and the cavities are opened on the upper and lower sides of the inner surface of the left side of the outer frame, and a bidirectional screw is movably connected in the inner cavity of the cavity, and a movable plate is threadedly connected on the upper and lower sides of the surface of the bidirectional screw, and plug blocks are fixedly installed on the front and rear sides of the inner sides of the two movable plates, and the front and rear sides of the surface of the outer frame are opened. The two mounting blocks are clamped in the inner cavity of the two clamping grooves, and hard springs are fixedly installed on the front and rear sides of the outer sides of the two movable plates, and connecting plates are fixedly installed on the front and rear sides of the right sides of the two movable plates, and a knob is fixedly installed on the top of the bidirectional screw.

[0009] Further preferably, limiting grooves are provided on both the front and rear sides of the inner cavities of the two cavities, and the front and rear sides of the two movable plates are slidably connected in the inner cavities of the four limiting grooves.

[0010] Further preferably, slots are provided on both the front and rear sides of the inner sides of the two cavities, and the four plug blocks penetrate the inner cavities of the four slots and are plugged into the inner cavities of the four holes.

[0011] Further preferably, movable grooves are opened on the right sides of the front and rear sides of the inner cavities of the two cavities, and the four connecting plates pass through the inner cavities of the four movable grooves and extend to the inner side of the outer frame.

[0012] Further preferably, card blocks are fixedly installed on both the front and rear sides of the inner cavities of the two card slots, and the four card blocks are all carded in the inner cavities of the four card slots.

[0013] Further preferably, outer sides of the four connecting plates are threadedly connected with bolts, and the four bolts are threadedly connected in the inner cavities of the four screw grooves.

[0014] Further preferably, the four slots and the four jacks are in the same vertical direction, and the four slots and the four jacks are interconnected.

[0015] Further preferably, both the front and rear sides of the inner side of the outer frame are provided with plug-in grooves, and both the front and rear sides of the mesh screen are snap-fitted into the inner cavities of the two plug-in grooves.

[0016] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0017] The utility model provides a disassembly mechanism. When the mesh screen is used for a long time and the mesh holes on its surface are deformed or blocked, the bolt is turned to move it out of the inner cavity of the screw groove, and then the knob is turned. At this time, the bidirectional screw rotates synchronously. Due to the rotation of the bidirectional screw, the movable plate moves outward along the surface of the bidirectional screw, and simultaneously drives the connecting plate and the plug block to move outward, and the plug block is moved out of the inner cavity of the jack, and then the mesh screen is pulled to the right to complete the disassembly of the mesh screen, which is convenient for subsequent cleaning or maintenance of the mesh screen. The disassembly method is relatively convenient, and the installation method of the screen is relatively cumbersome, which does not consume more time during disassembly, thereby affecting the overall screening efficiency. At the same time, since the hard spring itself has tension, the position of the movable plate is relatively stable. When the mesh screen is fixed, the parts in the disassembly mechanism will not become loose due to vibration, thereby affecting the fixing effect of the mesh screen.

[0018] Second, the utility model can limit the moving direction of the moving plate by setting the limit groove, so as to prevent the moving plate from rotating synchronously with the bidirectional screw rod, which in turn affects the disassembly of the mesh screen; by setting the slot, the moving direction of the plug block can be limited, so as to prevent the plug block from deviating when moving, so that the plug block cannot be removed from the inner cavity of the insertion hole, which affects the disassembly of the mesh screen; by setting the moving groove, the moving direction of the connecting plate can be limited, so as to prevent the direction of the connecting plate from deviating when moving, so that the bolt and the screw groove cannot be in the same vertical direction, resulting in the bolt being unable to be threadedly connected in the inner cavity of the screw groove, which in turn affects the fixing effect of the mesh screen; The arrangement of the card block can improve the stability of the mesh screen when it is installed, and can also limit the position of the installation block, so that the jack and the slot are in the same vertical direction, which is convenient for disassembling or installing the mesh screen. By setting the slot and the jack, since the two are in the same vertical direction and are connected to each other, the plug block can freely enter and exit the inner cavity of the jack along the slot, which is convenient for disassembling or installing the mesh screen. By setting the plug-in slot, the installation stability of the mesh screen can be further improved, and the moving direction of the mesh screen can also be limited, so that the installation block can be accurately plugged into the inner cavity of the card slot, which improves the convenience of disassembling or installing the mesh screen.

DETAILED DESCRIPTION

[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-5 As shown, the embodiment of the utility model provides a vibrating screen for limestone, comprising an outer frame 1 and a mesh screen 3, mounting blocks 4 are fixedly mounted on both the front and rear sides of the left side of the mesh screen 3, and slots 6 are provided on both the front and rear sides of the surfaces of the two mounting blocks 4, screw grooves 7 are provided on both the upper and lower sides of the left side of the mesh screen 3, and jacks 5 are provided on both the upper and lower sides of the two mounting blocks 4;

[0031] A disassembly mechanism 2 is provided on the inner surface of the left side of the outer frame 1, and the disassembly mechanism 2 includes a cavity 201, and the cavities 201 are opened on the upper and lower sides of the inner surface of the left side of the outer frame 1. A bidirectional screw 202 is movably connected in the inner cavity of the cavity 201, and a movable plate 203 is threadedly connected on the upper and lower sides of the surface of the bidirectional screw 202, and plug blocks 204 are fixedly installed on the front and rear sides of the inner sides of the two movable plates 203. The front and rear sides of the surface of the outer frame 1 are opened with clamping grooves 208, and the two mounting blocks 4 are clamped in the inner cavity of the two clamping grooves 208. Hard springs 205 are fixedly installed on the front and rear sides of the outer sides of the two movable plates 203, and connecting plates 206 are fixedly installed on the front and rear sides of the right sides of the two movable plates 203. A knob 209 is fixedly installed on the top of the bidirectional screw 202.

[0032] By setting the disassembly mechanism 2, when the mesh screen 3 is used for a long time and the mesh holes on its surface are deformed or blocked, the bolt 207 is turned to remove it from the inner cavity of the screw groove 7, and then the knob 209 is turned. At this time, the bidirectional screw 202 rotates synchronously. Due to the rotation of the bidirectional screw 202, the moving plate 203 moves outward along the surface of the bidirectional screw 202, and simultaneously drives the connecting plate 206 and the plug block 204 to move outward, and the plug block 204 is moved out of the inner cavity of the jack 5, and then the mesh screen 3 is moved to the inner cavity of the jack 5. The mesh screen 3 can be disassembled by pulling on the right side, which is convenient for subsequent cleaning or maintenance of the mesh screen 3. The disassembly method is relatively convenient, and the disassembly will not take a long time due to the complicated installation method of the screen, thereby affecting the overall screening efficiency. At the same time, since the hard spring 205 itself has tension, the position of the movable plate 203 is relatively stable. When the mesh screen 3 is fixed, the parts in the disassembly mechanism 2 will not become loose due to vibration, thereby affecting the fixing effect of the mesh screen 3.

[0033] Example 2

[0034] In one embodiment, the front and rear sides of the inner cavities of the two cavities 201 are provided with limiting grooves 210, the front and rear sides of the two movable plates 203 are slidably connected in the inner cavities of the four limiting grooves 210, the front and rear sides of the inner sides of the inner cavities of the two cavities 201 are provided with slots 211, the four plug blocks 204 penetrate the inner cavities of the four slots 211 and are plugged into the inner cavities of the four jacks 5, the right sides of the front and rear sides of the inner cavities of the two cavities 201 are provided with moving grooves 213, the four connecting plates 206 penetrate the inner cavities of the four moving grooves 213 and extend to the outer frame 1 On the inner side, the front and rear sides of the inner cavity of the two snap-in grooves 208 are fixedly installed with blocks 212, and the four blocks 212 are all snap-fitted into the inner cavities of the four snap-in grooves 6. The outer sides of the four connecting plates 206 are threadedly connected with bolts 207, and the four bolts 207 are threadedly connected into the inner cavities of the four screw grooves 7. The four slots 211 and the four sockets 5 are in the same vertical direction, and the four slots 211 and the four sockets 5 are interconnected. Plug-in grooves 8 are provided on the front and rear sides of the inner side of the outer frame 1, and the front and rear sides of the mesh screen 3 are snap-fitted into the inner cavities of the two plug-in grooves 8.

[0035] By setting the limiting groove 210, the moving direction of the movable plate 203 can be limited to prevent the movable plate 203 from rotating synchronously with the bidirectional screw 202, thereby affecting the disassembly of the mesh screen 3. By setting the slot 211, the moving direction of the plug block 204 can be limited to prevent the plug block 204 from offsetting when moving, so that the plug block 204 cannot be removed from the inner cavity of the socket 5, affecting the disassembly of the mesh screen 3. By setting the moving groove 213, the moving direction of the connecting plate 206 can be limited to prevent the connecting plate 206 from offsetting when moving, so that the bolt 207 and the screw groove 7 cannot be in the same vertical direction, resulting in the bolt 207 being unable to be threadedly connected to the inner cavity of the screw groove 7, thereby affecting the fixing effect of the mesh screen 3. By setting the card block 212, the stability of the mesh screen 3 during installation can be improved, and the position of the installation block 4 can also be limited, so that the socket 5 and the slot 211 are in the same vertical direction, which is convenient for disassembling or installing the mesh screen 3. By setting the slot 211 and the card block 212, since the two are in the same vertical direction and connected to each other, the plug block 204 can freely enter and exit the inner cavity of the card block 212 along the slot 211, which is convenient for disassembling or installing the mesh screen 3. By setting the plug-in slot 8, the installation stability of the mesh screen 3 can be further improved, and the moving direction of the mesh screen 3 can also be limited, so that the installation block 4 can be accurately plugged into the inner cavity of the card slot 208, which improves the convenience of disassembling or installing the mesh screen 3.

[0036] The utility model is in operation: when the screen holes on the surface of the mesh screen 3 are deformed or blocked after working for a long time, the bolt 207 is turned to move it out of the inner cavity of the screw groove 7, and then the knob 209 is turned. At this time, the bidirectional screw rod 202 rotates synchronously. Due to the rotation of the bidirectional screw rod 202, the movable plate 203 moves outward along the surface of the bidirectional screw rod 202, and synchronously drives the connecting plate 206 and the plug block 204 to move outward, and the plug block 204 is moved out of the inner cavity of the insertion hole 5. Then, the mesh screen 3 is pulled to the right to complete the disassembly of the mesh screen 3. When the mesh screen 3 is repaired or cleaned, it is removed again. The mesh screen 3 is clamped to the inner side of the outer frame 1. At this time, the mounting block 4 is inserted into the inner cavity of the clamping groove 208, and the clamping block 212 enters the inner cavity of the clamping groove 6. Then, the knob 209 is rotated in the opposite direction, and the bidirectional screw 202 rotates synchronously with the knob 209, and the movable plate 203 moves inward. As the movable plate 203 moves, the movable plate 203 drives the plug block 204 and the connecting plate 206 to move inward. The connecting plate 206 fits the surface of the mesh screen 3, and the plug block 204 is inserted into the inner cavity of the socket 5. Then, the bolt 207 is rotated to make it threadedly connected to the inner cavity of the screw groove 7, thereby completing the installation of the mesh screen 3.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
