Description

Siphon sludge collector with anti-detachment structure The present invention relates to a siphon sludge collector having a detachment prevention structure, and more specifically, to a technology that is installed in a sedimentation tank and allows a trolley to move along the sedimentation tank to suck up sludge from the bottom and discharge the sludge, while preventing the trolley from derailing from the rail during the movement process, thereby reducing noise and shock, reducing the occurrence of breakdowns, and increasing the sludge suction efficiency. Generally, a sludge collection device refers to a device that collects sludge settled on the bottom surface in primary sedimentation tanks, final sedimentation tanks, thickening tanks, etc., during the sewage treatment process of a water purification plant or sewage treatment plant, and removes it by discharging it to the outside. The types of such sludge collection devices include siphon-type sludge collectors, bridge-type sludge collectors, underwater trolley-type sludge collectors, chain-flight-type sludge collectors, and circular-type sludge collectors. Among the above sludge collection devices, the siphon method has an intermediate channel within the sedimentation tank structure and extends a pipe from the bottom of the sedimentation tank to form a siphon pipe through the intermediate channel, and uses the head difference between the sedimentation tank and the intermediate channel to suck up and discharge the sludge at the bottom of the sedimentation tank. In addition, the siphon-type sludge collector collects sludge as a trolley moves slowly along a rail installed on the upper part of the sedimentation tank. More specifically, the front of the trolley, which corresponds to the driving part, has a drive shaft that rotates by the power of a motor to rotate the driving wheel and move along the rail, while the rear of the trolley, which corresponds to the driven part, has the driving wheel that follows by the driving force from the front. However, due to various reasons (inconsistent rail installation spacing, differences in rail height, horizontal imbalance of the bogie, eccentric center of gravity caused by load concentration on the bogie, aging of the driving wheel or rail, rotational difference of the driving wheel, deformation of the bogie frame, etc.), there is a problem in which the driven driving wheel repeatedly derails from the rail or the protruding outer part of the driving wheel repeatedly rides up and down the rail. In actual field operations, the phenomenon of the driving wheel derailing from the rail does not occur frequently, but the problem of the outer edge of the driving wheel climbing onto the rail and then falling, causing a large impact and impact sound, occurs frequently. The bogie of a siphon sludge collector carries a heavy load because all devices for sludge collection are installed on the bogie. Therefore, since the impact generated when the driving wheel falls is proportional to the weight of the bogie, a high impact force is transmitted, which can cause damage to the axle or bearing and even deform the frame of the bogie. In addition, when an impact occurs, the shock is also transmitted to the siphon tube, causing the sludge settled at the bottom to rise again, which also has the problem of reducing collection efficiency. In addition, as the driving wheel climbs onto the rail, friction is concentrated on the protruding parts of the wheel, causing significant noise. Furthermore, the wear of both the driving wheel and the rail is accelerated, leading to the problem of an earlier replacement time. In the prior art related to this, Registered Utility Model No. 20-0426834 (underwater trolley type sludge collector with an anti-detachment guide) and Registered Utility Model No. 20-0328052 (underwater trolley equipped with an anti-detachment auxiliary wheel) disclose a technology that supports the direction of detachment through a guide and an auxiliary wheel. However, the aforementioned prior art corresponds to an underwater trolley, and the problem situation is different from that of a siphon-type sludge collector in which the trolley is exposed on the ground. Furthermore, if the rail path is abnormal and the position of the driving wheel moving along it is fixed, even if a configuration supporting the direction of deviation is added as in the aforementioned prior art, the fundamental problem is not resolved, so deviation cannot be prevented, and the guide configuration fails due to the force of deviation.
