Description

Technical Field

[0001] The utility model belongs to the technical field of pier column maintenance, and particularly relates to a pre-sediment filter for pier column maintenance water. Background Art

[0002] After the concrete pier is poured, if it is not cured, the evaporation of water in the concrete will cause the cement particles to lack sufficient bonding strength, resulting in flaking or powdery shedding on the concrete surface; at the same time, when the concrete does not yet have sufficient strength, the premature evaporation of water will also cause large shrinkage deformation and shrinkage cracks; so the initial maintenance work after concrete pouring is very important; due to water intake environment restrictions and maintenance cost considerations, most of the water used for pier maintenance comes from nearby irrigation canals or rivers. Due to the excessive mud content in the irrigation canals and rivers, the surface of the pier turns slightly yellow after the maintenance period, affecting the appearance quality.

[0003] After searching, the prior art announcement number is CN216474557U, which is a maintenance device for high pier construction, including a water spraying mechanism for maintaining the high piers, a water storage mechanism for providing water resources for maintenance, and a mounting mechanism for fixing the device on a lifting platform, wherein the water storage mechanism is installed on the side of the water spraying mechanism, and the mounting mechanism is fixed under the water storage mechanism; the processing process has the following disadvantages: although the cost can be reduced to a certain extent by collecting rainwater for maintaining the piers, the amount of rainwater is uncertain, and the rainwater is filtered through a filter net, which is not convenient to clean and will cause the filter net to be blocked, thereby affecting the maintenance efficiency of the piers.

[0004] The prior art announcement number is CN217896246U, which is a pier spray maintenance device; it includes a control system, a spray mechanism and a recovery mechanism; the spray mechanism is arranged at the upper end of the pier; the recovery mechanism is arranged at the lower end of the pier; its processing process has the following disadvantages: a recovery mechanism is arranged to recycle the maintenance water, and can filter the recovered maintenance water; however, only a part of the maintenance water can be recovered, and part of the maintenance water comes from nearby irrigation canals and rivers. Due to the excessive mud content in the irrigation canals and rivers, the surface of the pier turns slightly yellow after the maintenance period, affecting the appearance quality; and it is easy to cause blockage to the spray mechanism, affecting the maintenance efficiency of the pier.

At the same time, the filter cartridge and the filter screen are cleaned by the side scraper and the cleaning brush, which can speed up the backwashing rate; at the same time, the connecting rod drives the arc scraper to rotate along the bottom of the filter cartridge, which can scrape the mud and sand at the bottom of the filter cartridge to the sewage outlet to prevent the mud and sand from accumulating at the bottom of the filter cartridge.

[0015] 2) When the device filters the curing water, the side scraper and the cleaning brush are rotated to a position perpendicular to the spring guide shaft so that the side scraper and the cleaning brush do not block the movement of the filter screen; then the motor provides power to drive the rotating shaft to rotate, and the rotating shaft drives the cam to rotate. When the cam contacts the convex block, the cam squeezes the convex block, causing the convex block to drive the filter screen to deflect, and the corresponding spring is compressed, while other springs are stretched; when the cam is away from the convex block, the spring recovers and drives the filter screen to return, so that the filter screen vibrates, thereby being able to vibrate off the mud and sand on the surface of the filter screen to prevent the filter screen from being blocked;

[0016] 3) For high piers, the process of cleaning the pier surface after maintenance is cumbersome and poses safety hazards. However, the use of a pre-filter for curing water eliminates the need for manual cleaning of the pier surface after pier maintenance, thus avoiding safety hazards during the cleaning process.
