Description

Technical Field

[0001] The utility model relates to the technical field of machinery and equipment, in particular to a hydraulic reciprocating mud scraper which is easy to maintain. Background Art

[0002] Hydraulic reciprocating sludge scrapers are suitable for square or rectangular tanks requiring sedimentation, scraping, and concentrating sludge, including municipal waterworks, industrial water purification plants, municipal sewage treatment plants, industrial wastewater treatment plants, and flotation tanks. Silt formation in tanks is primarily caused by severe soil erosion in upstream areas, which carries sediment down with the flowing water. Once it reaches the dam or tank, it encounters obstacles (such as dam embankments) that prevent it from continuing to flow. Over time, this sediment accumulates and forms silt. Alternatively, in still water or slow-flowing environments, suspended matter and fine particles in the water gradually settle to the bottom, where, through physical, chemical, and biochemical processes, they form unconsolidated, soft, fine-grained soil, or silt. Regular tank cleaning and maintenance are essential to prevent excessive silt buildup.

[0003] The scraper blades of hydraulic reciprocating scrapers are typically large, monolithic pieces, requiring significant labor and resources to replace and repair. Furthermore, the hydraulic station is typically mounted on the inner wall of the tank, or even underwater in some cases. This makes parts replacement, routine inspection, and maintenance very complex. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0024] Reference Figures 1 to 5 The present invention provides a hydraulic reciprocating scraper that is easy to maintain. The scraper includes a scraper bridge 2. The bottom of each side of the scraper bridge 2 is fixedly connected to a fixed rod 4 made of stainless steel. The fixed rod 4 is fixedly connected to a fixed block 11 at one end away from the scraper bridge 2. A scraper blade 12 is provided at the bottom of the fixed block 11. There are multiple scrapers 12. The bottom of the scraper blade 12 is configured as a triangular pointed cone. The scraper blade 12 contacts the bottom of the rectangular water tank 1. The fixed block 11, the fixed rod 4, and the scraper bridge 2 are in the same vertical plane. The multiple scrapers 12 are provided to facilitate routine maintenance and reduce the consumption of manpower and material resources. The scraper blade 12 is configured as a triangular pointed cone at the bottom, which makes it easier to insert into the interior of the silt and scrape deeper. The fixed rod 4 is fixed by welding. The fixed block 11, the fixed rod 4, and the scraper bridge 2 can move synchronously in the same vertical plane. The bottom of each end of the scraper bridge 2 is fixedly connected to a support slider 3. The guardrails on both sides of the scraper bridge 2 are hollowed out. The hollow design not only saves material but also looks more beautiful.

[0025] A rectangular pool 1 is located beneath the scraper bridge 2. Slideways 8 are located near the edges of the upper surface of the pool 1. A support slider 3 fits within these slideways 8. A hydraulic cylinder 7 is fixedly connected to the inner side of the slideway 8. The piston rod of the hydraulic cylinder 7 is fixedly connected to the side of the support slider 3. The support slider 3 slides within the slideways 8, which are located on both sides of the pool 1. A sludge accumulation pool 9 is located at the bottom of the pool 1. The piston rod of the hydraulic cylinder 7 pushes the support slider 3 to move.

[0026] A pipe 6 is provided on the upper surface of the hydraulic cylinder 7, and a hydraulic station 5 is provided at the other end of the pipe 6. The lower surface of the hydraulic station 5 is fixedly connected to the upper surface of the rectangular pool 1. The hydraulic station 5, the pipe 6, and the hydraulic cylinder 7 form a cylinder power system.

[0027] The fixing block 11 is provided with a plurality of through circular holes, and the number of through circular holes of the fixing block 11 is double the number of the scraper blade 12. The scraper blade 12 is provided with a threaded hole on its upper surface, which is threadedly connected to the screw 10, and the shank of the screw 10 passes through the through circular hole on the fixing block 11.

[0028] Working Principle: To begin operation, the equipment is first inspected. Once this is complete, the hydraulic stations 5 on either side of the rectangular pool 1 are activated. These stations deliver power to the hydraulic cylinders 7 on either side via pipes 6. The piston rods of the hydraulic cylinders 7 push the support slides 3, which slide within the chute 8. This drives the scraper bridge 2 in synchronous motion. The fixed rods 4 and the scraper bridge 2 are in the same vertical plane and move synchronously with them. Because the fixed rods 4 are fixedly connected to the fixed block 11, the fixed block 11 also moves synchronously. The scraper blades 12, mounted on the fixed block 11, also move synchronously with the scraper bridge 2. This allows the scraper blades 12 to continue scraping the mud from the bottom of the rectangular pool 1. The piston rods of the hydraulic cylinders 7 are retractable, allowing the scraper bridge 2 to reciprocate, driving the scraper blades 12 back and forth across the bottom of the rectangular pool 1. The scraper blades 12 push the mud into the mud accumulation pool 9. When the equipment stops working, we need to inspect and maintain it. To facilitate maintenance, we divide the scraper blade 12 from a single piece into multiple easily removable parts. The scraper blade 12 is light in weight and easy for maintenance personnel to pick up, reducing the maintenance personnel's labor intensity. The most important power system is usually placed on the pool wall, which is not conducive to operator inspection and maintenance. Our device places it on the pool surface for easy daily inspection and maintenance.

[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention.
