Description

Technical Field

[0001] The utility model relates to the field of filter press equipment, in particular to a main beam cleaning structure of a filter press. Background Art

[0002] The filter press is a low-energy, high-efficiency intermittent pressurized filtration equipment used for solid-liquid separation of various slurries. The existing filter press plate moves back and forth on the main beams on both sides through the mounting parts. The filter residue dropped from the plate is not easy to clean on the main beam surface. Long-term accumulation can easily cause the filter press plate to move back and forth. At the same time, if the filter residue is stuck between the mounting parts on both sides of the plate, it will also affect the filtration effect. Utility Model Content

[0003] The utility model aims to provide a main beam cleaning structure for a filter press to overcome the shortcomings of the prior art.

[0004] The purpose of the utility model is achieved through the following technical solutions: a main beam cleaning structure of a filter press, including a filter plate assembly, the filter plate assembly is installed on the main beam, the filter plate assembly is connected to a driving device, the driving device drives the filter plate assembly to move back and forth on the main beam, characterized in that: connecting plates are symmetrically fixed on both sides of the driving device, a first spring is fixed on the connecting plate, a cleaning trolley is connected to the first spring, a plurality of guide rails are provided on the main beam, a cleaning trolley is installed on the guide rails, the cleaning trolley can move back and forth along the guide rails, a second spring is also connected between the cleaning trolley and the filter plate assembly, and a scraper is also provided on the cleaning trolley. The filter residue and dust dropped on the main beam are squeezed by the back and forth movement of the filter plate assembly and are not easy to clean up. This problem can be well solved by designing a scraper structure. An anti-dumping structure is also provided between the cleaning trolley and the guide rails.

[0005] Preferably, the anti-dumping structure includes guide grooves arranged on both sides of the guide rail, and the cleaning trolley is provided with a clamping protrusion matching the guide groove, and the clamping protrusion on the cleaning trolley cooperates with the guide groove to prevent the cleaning trolley from derailing or overturning during use. At the same time, the equipment operation efficiency is improved, the equipment downtime is reduced, and the damage to related parts caused by the overturning of the cleaning trolley is avoided.

[0006] Preferably, the cleaning trolley is also connected with an air inlet pipe and an air outlet pipe, and the air outlet pipe is connected to an air source. The scraper on the cleaning trolley shovels away the fallen filter residue and dust in time and further blows the filter residue and dust clean through the gas in the air outlet pipe.

[0007] Preferably, the guide rails are provided with two through grooves, and the through grooves on adjacent guide rails are staggered along the direction of the guide rails. During the cleaning process, the dust swept out between the two guide rails is not easy to be blown out. By designing the through grooves, when the filter residue and dust are shoveled to the through groove position, the gas in the exhaust pipe can blow the filter residue and dust out through the through grooves. Considering that if the through grooves on adjacent guide rails are aligned, when the cleaning trolley passes through the through grooves, the cams at both ends need to leave the guide grooves, which may easily cause the trolley to roll over, or the cams may not easily enter the guide grooves again due to the shaking of the upper and lower positions of the cleaning trolley, the through grooves on two adjacent guide rails are staggered along the direction of the guide rails to prevent the cams on the two guide rails from being separated from the guide grooves at the same time.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The scraper is designed to prevent the filter residue and dust that fall on the main beam from being squeezed by the back and forth movement of the filter press plate assembly, forming lumps that are difficult to clean. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figure 1 , 2As shown in Figure 3, a main beam cleaning structure of a filter press includes a filter plate assembly 1, the filter plate assembly 1 is mounted on the main beam 2, a driving device 3 is connected to the filter plate assembly 1, and the driving device 3 drives the filter plate assembly 1 to move back and forth on the main beam 2, characterized in that: connecting plates 4 are symmetrically fixedly connected on both sides of the driving device 3, a first spring 5 is fixedly connected to the connecting plate 4, a cleaning trolley 6 is connected to the first spring 5, a plurality of guide rails 7 are provided on the main beam 2, a cleaning trolley 6 is installed on the guide rail 7, the cleaning trolley 6 can move back and forth along the guide rail 7, a second spring 8 is also connected between the cleaning trolley 6 and the filter plate assembly 1, and a scraper 9 is also provided on the cleaning trolley 6. The filter residue and dust dropped on the main beam 2 are squeezed by the back and forth movement of the filter plate assembly 1 and are not easy to clean up. By designing the scraper 9 structure, this problem can be well solved. An anti-dumping structure is also provided between the cleaning trolley 6 and the guide rail 7.

[0021] In this embodiment, when the filter press is working, the driving device 3 drives the filter press plate assembly 1 to move rightward (such as Figure 1 ), the slurry is squeezed, and the air source (not shown) is started, and the second spring 8 drives the cleaning trolley 6 to move rightward for cleaning. When the filter press stops working, the first spring 5 pulls the cleaning trolley 6 back to the limit range of the first spring 5 contraction. The anti-dumping structure includes guide grooves 10 arranged on both sides of the guide rail 7, and the cleaning trolley 6 is provided with a clamping protrusion 11 matching the guide groove 10. The clamping protrusion 11 on the cleaning trolley 6 cooperates with the guide groove 10 to avoid the derailment and rollover of the cleaning trolley 6 during use. At the same time, it improves the equipment operation efficiency, reduces the equipment failure downtime, and avoids the damage of related parts caused by the rollover of the cleaning trolley 6.

[0022] The cleaning trolley 6 is also connected with an air inlet pipe 12 and an air outlet pipe 13, and the air outlet pipe 13 is connected to an air source. The scraper 9 on the cleaning trolley 6 shovels away the fallen filter residue and dust in time and further blows the filter residue and dust clean through the gas in the air outlet pipe 13.

[0023] The guide rails 7 are provided with two, and the guide rails 7 are also provided with through grooves 14. The through grooves 14 on adjacent guide rails 7 are staggered along the direction of the guide rails 7. During the cleaning process, the dust swept out between the two guide rails 7 is not easy to be blown out. By designing the through grooves 14, when the filter residue and dust are shoveled to the position of the through grooves 14, the gas in the exhaust pipe 13 can blow the filter residue and dust out through the through grooves 14. Considering that if the through grooves 14 on adjacent guide rails 7 are aligned, when the cleaning trolley 6 passes through the through grooves 14, the protrusions 11 at both ends need to leave the guide grooves 10, which may easily cause the vehicle to overturn, or the protrusions 11 may not easily enter the guide grooves 10 again due to the shaking of the upper and lower positions of the cleaning trolley 6, the through grooves 14 on the two adjacent guide rails 7 are staggered along the direction of the guide rails 7 to prevent the protrusions 11 on the two guide rails 7 from being separated from the guide grooves 10 at the same time.
