DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] The existing disclosed disc filter special filter cloth realizes the preliminary rapid positioning of the disc filter cloth on the filter cloth mounting frame by cooperating and engaging the limit clamping block with the limit clamping groove, and uses a plurality of assembly bolts to pass through the first assembly hole and the second assembly hole to realize the fixed connection of the disc filter cloth on the filter cloth mounting frame. When the disc filter cloth is in operation, its surface will absorb more impurities, and these impurities will increase the dead weight of the disc filter cloth under accumulation, resulting in the assembly bolts between the disc filter cloth and the filter cloth mounting frame being subjected to gradually increasing pressure, which is easy to cause the assembly bolts to deform, so that workers cannot remove the disc filter cloth from the filter cloth fixing frame, which is not conducive to workers replacing the disc filter cloth for the disc filter in daily work. The present embodiment provides a disc filter special filter cloth, such as Figure 1-Figure 4As shown, it includes a filter cloth body 1 and a fixing frame 2 for installing the filter cloth body 1. A fixing frame 3 is provided on the peripheral surface of the filter cloth body 1. A connecting mechanism 4 is provided in the fixing frame 2 for workers to replace the filter cloth body 1. When workers need to replace the filter cloth body 1 for the disc filter, the fixing frame 2 and the fixing frame 3 can be quickly positioned and fixed through the connecting mechanism 4, while the contact area between the fixing frame 3 and the fixing frame 2 is increased to the greatest extent, effectively preventing the overall self-weight of the fixing frame 3 and the filter cloth body 1 from increasing when a large amount of impurities are attached to the surface of the filter cloth body 1, thereby damaging the connecting mechanism 4.

[0027] When a large amount of impurities are attached to the surface of the filter cloth body 1 and the deadweight of the fixing frame 3 and the filter cloth body 1 is increased, the extrusion force between the fixing frame 3 and the fixing frame 2 is increased, which may easily lead to deformation of the assembly bolts and make it impossible to separate the filter cloth body 1 from the fixing frame 2. The connecting mechanism 4 includes a plurality of rectangular grooves 41 arranged on the surface of the fixing frame 3. The rectangular grooves 41 have a certain length, so that the rectangular blocks 42 can slide in a directional manner in the rectangular grooves 41. The plurality of rectangular grooves 41 are all slidably connected with rectangular blocks 42. The shapes of the rectangular blocks 42 and the rectangular grooves 41 fit each other, so that the rectangular blocks 42 can drive the connecting rod 43 to make a linear motion. The upper end of the rectangular block 42 is provided with a connecting rod 43. The length of the connecting rod 43 is the same as that of the rectangular block 42. The lengths of the grooves 41 are the same, which is beneficial for workers to transport the filter cloth body 1 and the fixed frame 3, and the connecting rod 43 will not protrude to affect the workers' handling. A slider 44 is provided at the lower end of the connecting rod 43. When the connecting rod 43 is in a protruding state, multiple sliders 44 can be guided into the corresponding first slide grooves 45 to achieve preliminary positioning between the fixed frame 3 and the fixed frame 2. The surface of the fixed frame 2 is provided with a first slide groove 45 slidably connected to the slider 44. The length of the first slide groove 45 is greater than the length of the slider 44, which is beneficial for the fixed frame 2 and the fixed frame 3 to fit each other when the slider 44 fully enters the first slide groove 45. A fixing piece 46 for fixing the slider 44 in the first slide groove 45 is provided in the fixed frame 2, and the slider can be 44 is fixed in the first slide groove 45, which is conducive to limiting the close contact between the fixing frame 2 and the fixing frame 3. Since two blocking blocks 47 are symmetrically arranged in the first slide groove 45, the surface of the slider 44 is provided with a second slide groove 48 for sliding connection with the blocking block 47, and the surface of the slider 44 is provided with a card slot 49. When the worker connects and fixes the new filter cloth body 1 to the fixing frame 2, and moves the rectangular block 42 to one end of the rectangular groove 41, so that the connecting rod 43 and the slider 44 remain in a protruding state, and aligns the multiple sliders 44 with the multiple first slide grooves 45 on the surface of the fixing frame 2, respectively, the slider 44 will be pushed into the first slide groove 45, and at this time, the blocking block 47 will slide in the second slide groove 48 on the surface of the slider 44. , it can be seen that the contact force point between the fixed frame 3 and the fixed frame 2 is at the position where the blocking block 47 contacts the first slide groove 45. Since the blocking block 47 in the fixed frame 2 and the second slide groove 48 in the slider 44 are both integrated designs, the stability of the contact point position is increased to prevent the contact area from being damaged and affecting the workers' removal of the filter cloth body 1 from the fixed frame 2. At the same time, when the slider 44 moves at one end in the first slide groove 45, it will trigger the fixing member 46 to work and fix the slider 44 at this position in the first slide groove 45. At the same time, the worker can manually trigger the fixing member 46 again to release the restriction on sliding, which is beneficial for workers to quickly and conveniently replace the filter cloth body 1 for the disc filter in their daily work.

[0028] When the slider 44 is fixed in the first chute 45, the worker needs to replace the filter cloth body 1 for the disc filter, so it is necessary to stably fix the filter cloth body 1 on one side of the fixing frame 2, and it is also convenient for the worker to remove the filter cloth body 1 from one side of the fixing frame 2, so it is necessary to automatically fix and restrict the slider 44, and manually release the restriction on the slider 44. The fixing member 46 includes a groove 461 arranged in the fixing frame 2 and connected to the first chute, a circular groove 462 connected to the groove 461 is arranged on the surface of the fixing frame 2, and a push rod 463 sliding in the circular groove 462 is arranged in the fixing frame 2, and one side of the push rod 463 has a surface A linkage assembly 464 in contact with the slider 44 is provided on the surface, and a first spring 465 fixedly connected to the push rod 463 is provided in the groove 461. When the slider 44 moves in the first slide groove 45 and is fixed in the first slide groove 45 by the linkage assembly 464, the worker can press the push rod 463 from the outside to make the push rod 463 move into the groove 461 along the circular groove 462 and compress the first spring 465, so that the linkage assembly 464 follows the push rod 463 to move downward in the groove 461 and separate from the slider 44. At this time, the worker releases the restriction on the slider 44 and can manually separate the fixed frame 3 from the fixed frame 2.

[0029] When the slider 44 enters the first slide groove 45, only the initial positioning between the fixed frame 3 and the fixed frame 2 is achieved. At this time, the fixed frame 3 can drive the slider 44 to move in the opposite direction in the first slide groove 45, so that the filter cloth body 1 is separated from the fixed frame 3, which is not conducive to maintaining the stability of the filter cloth body 1 of the disc filter when it is working. The linkage assembly 464 includes a rectangular frame 4641 arranged on the surface of one side of the push rod 463, and a long plate 4642 in contact with the first slide groove 45 is slidably connected in the rectangular frame 4641, and a second spring 4643 fixedly connected to one end of the long plate 4642 is arranged in the rectangular frame 4641, and an inclined block 4644 and a fixed rod 4645 are respectively arranged at both ends of the surface of one side of the long plate 4642. When the slider 44 slides in the first slide groove 45, the slider 44 One side will contact and squeeze the inclined surface of the inclined block 4644, so that the long plate 4642 moves in a directional manner from one end of the rectangular frame 4641 to the other end, and compress the second spring 4643, so that the fixing rod 4645 is close to the slider 44. When the inclined block 4644 and the long plate 4642 stop moving, the fixing rod 4645 contacts the slot 49. Since the inclined block 4644 is squeezed and contacted with the rectangular block 42, the position of the long plate 4642 in the rectangular frame 4641 is fixed and the compression amount of the second spring 4643 remains unchanged, so that the fixing rod 4645 is always in contact with the slot 49, thereby limiting the reverse movement of the slider 44 in the first slot 45, which is conducive to automatically limiting the position of the fixing slider 44 in the first slot 45 after the slider 44 moves to a certain distance in the first slot 45.

[0030] Example 2

[0031] When the rectangular block 42 slides at one end in the rectangular groove 41, the protruding state of the connecting rod 43 and the sliding block 44 is conducive to making the sliding block 44 slide in the first sliding groove 45. When the rectangular block 42 moves to the opposite end of the rectangular groove 41, the protruding state of the connecting rod 43 and the sliding block 44 is reduced, which is conducive to the workers when they carry the fixed frame 3 and the filter cloth body 1. The rectangular block 42 is easily affected by gravity and moves back and forth in the rectangular groove 41. When the workers dock the fixing frame 2 and the fixing frame 3, it is impossible to ensure that multiple sliding blocks 44 enter the corresponding first sliding grooves 45 at the same time. On the basis of Example 1, Figure 5 As shown, the rectangular block 42 is made of iron, and magnets 410 are provided at both ends of the rectangular groove 41, which are magnetically connected to the rectangular block 42. When the rectangular block 42 moves to one end of the rectangular groove 41, the rectangular block 42 will be adsorbed and fixed at this position in the rectangular groove 41, which is beneficial for workers to control the movement of the rectangular block 42 in the rectangular groove 41 and maintain a specific movement state, and is beneficial to prevent the rectangular block 42 from moving back and forth in the rectangular frame 4641, affecting the workers' replacement of the filter cloth body 1 of the disc filter in their daily work.
