Description

Screen mesh fixing device of vibrating screen

Technical Field

The utility model relates to a field of grit production, concretely relates to shale shaker screen cloth fixing device.

Background

The shale shaker is the commonly used vibration screening instrument in the mine grit production line, because the high-speed operation of shale shaker during operation leads to its screen cloth wearing and tearing comparatively serious, therefore the screen cloth on the shale shaker is changed generally more frequently, causes very big trouble to the operation maintenance. The existing screen is generally fixed on a screen frame by adopting devices such as a pressing plate, a bolt and the like, so that the structure causes the screen to be troublesome to mount and dismount, the maintenance time and the cost are higher, and the larger operation cost is caused.

Notification No. CN 209829562U discloses a shale shaker screen cloth fixing device, and it includes the screen frame, connecting bolt, compresses tightly strip steel, yielding rubber strip, screen cloth, stay tube, backup pad isotructure, and this patent has disposed special yielding rubber strip between the screen cloth of shale shaker and bank of screens, has carried out certain slowing down to the vibrational force to timely change after the yielding rubber strip damages, make the screen cloth reach longest life, reduce maintenance duration. But the device is simple to do some shock attenuation effects, and the screen cloth is changed comparatively complicacy, difficulty moreover, and the structure of device is also comparatively complicated simultaneously, is unfavorable for the implementation of production scene.

Grant publication No. CN 207709375U discloses a vibrating screen fixing device, which includes a support part below the screen for supporting the screen and a wedge press-fitting part above the screen for pressing the screen. Utilize the wedge steel sheet to penetrate the slot part of fluting round steel easily to wear the split pin and prevent that the wedge steel sheet from droing, thereby compress tightly the screen cloth fixedly, remove the split pin during the dismantlement, reverse beat the wedge steel sheet can, need not to use the spanner to twist the bolt. However, the whole structure of the device is relatively complex, and simple and rapid loading and unloading cannot be achieved.

No. CN 207138260U discloses a fixing device of shale shaker screen cloth, it is including setting up the support angle bar in the screen cloth lower part, the clamp plate of setting on screen cloth upper portion, the striker plate of setting on screen cloth clamp plate, T type head bolt and the complex nut that is used for fixed support angle bar and screen cloth clamp plate, overhead sleeve pipe of nut, the device can effectively protect the impact and the collision of material to T type bolt, the protection bolt fastener, through the fixed T type bolt of draw-in groove, prevent not hard up of screen cloth, improve equipment security. But the vibrating screen still has the defect of complex structure, only the bolt head of the pressure plate is protected, the current situation that the screen is troublesome to assemble and disassemble is not changed, and the working efficiency of the vibrating screen is reduced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide a shale shaker screen cloth fixing device, have simple structure, loading and unloading convenient advantage, shortened the shale shaker by a wide margin and maintained the required time, improved production efficiency.

The purpose of the utility model is accomplished through following technical scheme: the screen fixing device for the vibrating screen comprises a screen, a guide rail, a countersunk bolt, a screen plate supporting piece, a fixing bolt pair and a support frame, wherein the bottom of the screen is provided with a groove for matching with bosses on the left side and the right side of the guide rail to connect and fix the guide rail and the screen; one end of a sieve plate supporting piece with an L-shaped cross section leans against the bottom of the sieve screen and is fixedly connected with the guide rail through a countersunk bolt, the other end of the sieve plate supporting piece is fixedly connected with the supporting frame through a fixing bolt pair, and the bottom of the supporting frame is welded on the cross beam.

The utility model has the advantages that: the purpose of fixing the screen is achieved by matching the lug bosses on the guide rails with the grooves at the bottom of the screen; the whole structure is greatly simplified, the screen is more convenient and simple to replace, the maintenance time of the vibrating screen is greatly shortened, and the operation efficiency is improved.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Description of reference numerals: the screen comprises a screen 1, a guide rail 2, a boss 2-1, a countersunk head bolt 3, a screen plate support member 4, a fixed bolt pair 5, a support frame 6 and a cross beam 7.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

example (b): as shown in the attached figure 1, the vibrating screen fixing device comprises a screen 1, a guide rail 2, a countersunk bolt 3, a screen plate support 4, a fixing bolt pair 5 and a support frame 6, wherein a groove is formed in the bottom of the screen 1 and is used for being matched with bosses 2-1 on the left side and the right side of the guide rail 2 to connect and fix the guide rail 2 and the screen 1; one end of a sieve plate supporting piece 4 with an L-shaped cross section leans against the bottom of the sieve screen 1 and is fixedly connected with the guide rail 2 through a countersunk head bolt 3, the other end of the sieve plate supporting piece 4 is fixedly connected with a supporting frame 6 through a fixing bolt pair 5, and the bottom of the supporting frame 6 is welded on a cross beam 7.

The utility model discloses a working process: when the screen is installed, the screen 1 is pressed downwards and forcefully, so that the groove at the lower part of the screen 1 clamps the boss 2-1 of the guide rail 2, and the screen 1 is fixed; when the screen cloth 1 is damaged and replaced, the screen cloth 1 can be directly and powerfully pulled out from the guide rail 2, so that the loading and unloading speed of the screen cloth 1 is very quick and simple, and the operation efficiency is improved. Meanwhile, the screen 1 is fixed without parts such as a pressing plate and a connecting bolt, and the structure is greatly simplified.

It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
