Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to an automatic sludge scraping and suction device for a sludge machine. Background Technology

[0002] In traditional water treatment processes, sedimentation tanks are used to separate suspended solids from water. The sludge settled at the bottom of the tank needs to be removed periodically by a sludge scraper. Currently, the widely used traveling or radial flow sludge scrapers have the following obvious drawbacks: Since most components such as scrapers and suction pipes are underwater for extended periods, it is usually troublesome to drain the water from the tank when maintenance is required, or maintenance personnel may have to dive into the water for dangerous operations. Some traveling sludge scrapers are typically operated in a one-way sludge scraping and suction mode, that is, they move from the head of the tank to the tail of the tank to scrape and suck up sludge, and then the traveling trolley returns empty to the head of the tank to scrape and suck up sludge again. About 50% of the operating time is wasted on the empty return trip. Utility Model Content

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] This utility model provides an automatic sludge scraping and suction device for a sludge machine. By setting up a multi-stage hydraulic telescopic rod, when maintenance is required, the multi-stage hydraulic telescopic rod pulls the processing support, so that components such as the scraper and suction pipe are exposed above the water surface, which facilitates maintenance operations without the need to drain the water or submerge for operation. The processing support is equipped with scrapers and suction pipes on both the left and right sides. Sludge scraping and suction can be performed when the machine frame moves from the head to the tail of the pool and when it moves back from the tail to the head of the pool.

[0029] Figures 1-6 The diagram shown is an overall structural schematic of one embodiment of the automatic sludge scraping and suction device for a sludge machine according to this utility model. Please refer to [link / reference]. Figures 1-6An automatic sludge scraping and suction device for a sludge machine according to this embodiment includes a frame 1. The frame 1 includes a second opening 102. The upper end of the frame 1 has a second opening 102. A fixed frame 103 is provided at the upper end of the frame 1. A multi-stage hydraulic telescopic rod 105 is fixedly provided at the upper end of the fixed frame 103. The lower telescopic end of the multi-stage hydraulic telescopic rod 105 is fixedly connected to a processing bracket 106 through the second opening 102. Support plates 4 are fixedly connected to both the left and right sides of the processing bracket 106. A fixed plate 5 is fixedly connected to the lower end of the support plate 4. A scraper 9 is provided below the fixed plate 5.

[0030] The fixing bracket 103 is located outside the second port 102. The ear plates fixed on the left and right sides of the fixing bracket 103 are provided with second bolts 104. The lower end of the second bolts 104 is threaded into the second bolt hole opened on the frame 1. The upper end of the processing bracket 106 is fixedly connected to the guide post 107 by the third bolt 108. The upper end of the guide post 107 passes through the first port 101. The first port 101 is opened through the upper end of the frame 1 and is located between the second ports 102.

[0031] By incorporating a multi-stage hydraulic telescopic rod 105, the treatment support 106 can be pulled by the multi-stage hydraulic telescopic rod 105 during maintenance, allowing components such as the scraper 9 and suction pipe 119 to protrude above the water surface for convenient maintenance. A protective sleeve is provided on the outside of the multi-stage hydraulic telescopic rod 105. This protective sleeve is a retractable protective cover, typically made of a corrosion-resistant and wear-resistant flexible material, such as polyurethane or rubber. This protective cover acts like a sealed, pleated bellows, completely isolating the hydraulic cylinder's telescopic rod from the sewage environment. Regardless of how the hydraulic cylinder extends or retracts, the protective cover extends or retracts accordingly, always ensuring that the internal hydraulic rod remains in a clean and dry environment. This structure is a current technology.

[0032] The upper end of the processing bracket 106 is fixedly connected to slide rails 109 near the left and right sides. A slide frame 110 is slidably connected to the slide rails 109. A connecting bracket 114 is fixedly connected to the outer side of the slide frame 110. A connecting plate frame 111 is fixedly connected to the inner side of the slide frame 110. The front side of the connecting plate frame 111 is fixedly connected to the telescopic end of the first hydraulic telescopic rod 112. The first hydraulic telescopic rod 112 is fixedly installed on the support base 113. The support base 113 is fixedly set at the upper end of the processing bracket 106.

[0033] The first hydraulic telescopic rod 112 drives the slide 110 to move back and forth on the slide rail 109 via the connecting plate frame 111, thereby adjusting the movement of the suction pipe 119, which helps the suction pipe 119 to fully suck up mud. The extension stroke of the first hydraulic telescopic rod 112 driving the slide 110 is controlled by setting a limit switch.

[0034] A second hydraulic telescopic rod 115 is fixedly installed on the upper end of the connecting bracket 114. An external plate frame 116 is fixedly connected to the telescopic end of the second hydraulic telescopic rod 115. A suction tube bracket 117 is installed on the upper end of the external plate frame 116. A fourth bolt 118 is installed through the second through hole at the upper end of the suction tube bracket 117. The lower end of the fourth bolt 118 is threaded into the third bolt hole on the external plate frame 116. A sludge suction pipe 119 is fixedly installed through the suction tube bracket 117. Track wheels 2 are rotatably connected to the front and rear sides of the frame 1. The wheel surface of the track wheel 2 is in contact with the steel rail 3. The steel rail 3 is laid on the top of the two long side walls of the pool.

[0035] Under the action of the second hydraulic telescopic rod 115, the suction pipe bracket 117 is moved and adjusted via the external plate frame 116, thereby appropriately adjusting the height of the sludge suction pipe 119 for sludge suction. Furthermore, a sludge interface meter is installed at the bottom of the pool to measure the sludge concentration at different water depths in real time and accurately calculate the thickness of the sludge layer. This technology is existing. If a thick sludge layer with high concentration is detected, the speed of the scraper's motor is reduced via PLC-controlled frequency converter. This allows the equipment to have a longer residence time in areas with high sludge load, ensuring thorough scraping and suction, and preventing incomplete scraping or blockage of the discharge pipe due to excessive speed. If a thin sludge layer with low concentration is detected, the speed is reduced via PLC-controlled frequency converter. The existing technology allows for either increasing the speed of the walking motor to quickly pass through the area or pausing operation until the sludge accumulates to a certain thickness before restarting. This walking motor primarily drives the movement of the track wheel 2. The axle of the track wheel 2 is connected to the output shaft of the walking motor via a reducer. The reciprocating movement is automatically controlled by limit switches or anti-collision bars installed at both ends of the rail 3. Protective sleeves are also installed on the outer sides of the second hydraulic telescopic rod 115 and the first hydraulic telescopic rod 112. The sludge interface meter is model Endress+HauserCUS51D, the controller is model Siemens SIMATICS7-1200, and the frequency converter is model Siemens SINAMICSG120X.

[0036] The lower end of the fixed plate frame 5 is provided with a first bolt hole 6. The scraper 9 is fixedly installed at the lower end of the mounting plate frame 7. A first bolt 8 is installed through the second through hole on the mounting plate frame 7. The upper end of the first bolt 8 is threaded into the first bolt hole 6.

[0037] The scraper 9 is threaded into the first bolt hole 6 through the second through hole opened on the mounting plate 7 by the first bolt 8, which is used to fix the scraper 9. The scraper 9 are evenly distributed on the treatment bracket 106, and each scraper 9 corresponds to a sludge suction pipe 119, which makes the scraper 9 modular. When a single scraper 9 is damaged and needs to be replaced, the corresponding first bolt 8 is removed to replace the scraper 9. There are two sets of sludge suction pipes 119, one on the left and one on the right. Each set of sludge suction pipes 119 is connected to a sludge discharge main pipe. The sludge sucked up by the sludge suction pipes 119 all flow into this sludge discharge main pipe, which is connected to the sludge suction pump.

[0038] Combination Figures 1-6 The automatic sludge scraping and suction device of this embodiment is used as follows: The frame 1 moves on the rail 3 via the track wheel 2, scrapes the sludge with the scraper 9, and sucks the sludge under the action of the suction pipe 119. Under the action of the second hydraulic telescopic rod 115, the suction pipe support 117 is moved and adjusted by the external plate frame 116, so as to appropriately adjust the height of the suction pipe 119 for sludge suction. The first hydraulic telescopic rod 112 drives the slide 110 to move back and forth on the slide rail 109 through the connecting plate frame 111, so as to move and adjust the suction pipe 119, which helps the suction pipe 119 to fully suck up sludge. When maintenance is required, the treatment support 106 is pulled by the multi-stage hydraulic telescopic rod 105, so that the scraper 9 and the suction pipe 119 are exposed above the water surface for convenient maintenance.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
