Description

Technical Field

[0001] The utility model relates to the technical field of anti-blocking devices, in particular to an anti-blocking device for an integrated pump station. Background Art

[0002] The integrated pump station is a new type of equipment that integrates submersible pumps, pump station equipment, sewage removal screen equipment, control system and remote monitoring system. It has many advantages: high integration: multiple equipment and components are integrated into a compact box, saving installation space; convenient construction: greatly reducing the time and workload of on-site construction, usually only simple basic construction and equipment installation are required; high efficiency and energy saving: the use of advanced water pumps and control systems can achieve efficient operation and reduce energy consumption; high stability: after careful design and optimization, the operation is stable and reliable, and the probability of failure is reduced. Integrated pump stations are widely used in municipal drainage: used for the collection and transportation of urban rainwater and sewage, and to improve urban drainage systems. For example, in some old urban areas, drainage facilities are aging. By installing an integrated pump station, the drainage capacity can be effectively improved and the problem of waterlogging in the rainy season can be solved. The water inlet pipe of the existing integrated prefabricated pump station is generally filtered through a screen. Impurities and sludge may be blocked in the pipe, which may affect its use. There is a lack of an anti-blocking structure and device, which may be inconvenient to use.

[0003] For example, a Chinese patent document discloses an anti-blocking device for an integrated pump station (Announcement No.: CN212772764U). Although this patent provides a filter hole on the cylinder to filter the water flowing into the cylinder, and a spiral sewage discharge mechanism is provided in the cylinder to push the impurities and sludge remaining in the cylinder after filtration to the sewage outlet provided on the cylinder for discharge, the filtered water flows to the pump station water inlet pipe through structures such as a conical bucket and a bend pipe, thereby effectively filtering the water before it flows into the pump station water inlet pipe, preventing impurities in the water from causing pipe blockage after flowing into the pump station water inlet pipe. The impurities and sludge contained in the water are also discharged. Compared with traditional grille blocking, the device of the utility model has a spiral sewage discharge mechanism, which can quickly and thoroughly transport the impurities and sludge under the blockage and discharge them uniformly from the sewage outlet, avoiding blockage inside the cylinder and affecting the filtering effect and the normal operation of the filtering operation.

[0004] However, after long-term use, fine impurities and sludge will be adsorbed on the filter holes of the cylinder, thereby reducing the speed of water flow and affecting the water supply efficiency of the pump station. After a certain period of use, manual cleaning is required, which not only increases the labor intensity, but also greatly reduces the cleaning efficiency. Utility Model Content

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0028] See also Figure 1-Figure 5 As shown, this embodiment is an anti-blocking device for an integrated pump station, comprising a processing box 1, an outer gear ring 2 being fixedly connected to the upper surface of the processing box 1, an annular filter block 3 being fixedly sleeved on the inner wall of the processing box 1, the outer surface of the annular filter block 3 being provided with mounting grooves 4 distributed in an annular array, an arc-shaped filter screen 5 being fixedly mounted on the inner wall of the mounting groove 4, an annular positioning groove 6 being provided on the outer surface of the annular filter block 3, an arc-shaped slider 7 being slidably connected to the inner wall of the annular positioning groove 6;

[0029] The outer surface of the arc-shaped slider 7 is provided with a clearing device, and the clearing device includes a arc-shaped mounting plate 8 , the inner surface of the arc-shaped mounting plate 8 is fixedly connected to the outer surface of the arc-shaped slider 7 .

[0030] A servo motor 81 is fixedly mounted on the inner wall of the arc-shaped mounting plate 8, and a rotating shaft 82 is fixedly mounted on the output shaft of the servo motor 81 through a coupling. A driving gear 83 is fixedly sleeved on the outer surface of one end of the rotating shaft 82, and the tooth surface of the driving gear 83 meshes with the tooth surface of the outer gear ring 2. An L-shaped fixing block 84 is fixedly connected to the upper surface of the arc-shaped mounting plate 8, and a movable groove 85 is provided on the upper surface of the L-shaped fixing block 84. The inner walls on both sides of the movable groove 85 are fixedly connected with guide rods 86, and the outer surface of the guide rods 86 is movably sleeved with guide blocks 87. The outer surface of the guide block 87 is slidingly connected to the inner wall of the movable groove 85. A contraction spring 88 is fixedly connected to the surface of one side of the guide block 87, and one end of the contraction spring 88 is fixedly connected to the inner wall of one side of the movable groove 85. The lower surface of the guide block 87 is fixedly connected to the driving block 89.

[0031] Start the servo motor 81, and the servo motor 81 drives the driving gear 83 to rotate through the rotating shaft 82. The rotation of the driving gear 83 drives the arc-shaped slider 7 to slide within the annular positioning groove 6 through the meshing outer gear ring 2. The movement of the arc-shaped slider 7 drives the arc-shaped mounting plate 8 to rotate in a circle along the annular filter block 3. The movement of the L-shaped fixing block 84 of the arc-shaped mounting plate 8 moves. The movement of the L-shaped fixing block 84 drives the driving block 89 to perform a circular motion through the guide block 87. A handle for easy pulling is provided on one side of the driving block 89.

[0032] The inner wall of the driving block 89 is movably connected with a symmetrically distributed limit rod 810, and one end of the two limit rods 810 is fixedly connected to an arc-shaped cleaning block 811. The outer surface of the arc-shaped cleaning block 811 contacts the inner wall of the annular filter block 3, and one side surface of the arc-shaped cleaning block 811 contacts one side surface of the driving block 89. The lower end of the annular filter block 3 is fixedly connected to a conical collecting cylinder 812, and the lower end of the conical collecting cylinder 812 is fixedly connected to a sewage pipe 813. One end of the sewage pipe 813 passes through and extends to the lower surface of the treatment box 1. One side surface of the treatment box 1 is fixedly connected to a pump station water inlet pipe 814.

[0033] The arc surface of the arc cleaning block 811 is provided with elastic bristles, which facilitates the cleaning of impurities and sludge. The movement of the arc cleaning block 811 cleans the adsorbed impurities and sludge, and the cleaned impurities and sludge fall to the bottom of the conical collecting cylinder 812. The outer surface of the sewage pipe 813 is provided with a solenoid valve for controlling the connection, and by opening the solenoid valve of the sewage pipe 813, the collected impurities and sludge are discharged. The outer surface of the pump station water inlet pipe 814 is provided with a solenoid valve for controlling the connection.

[0034] By setting up a clearing device, it is possible to automatically clean the impurities and sludge adsorbed on the curved filter 5, thereby ensuring the water supply efficiency of the water pump inlet pipe. The automatic cleaning reduces manual labor, and the cleaning without stopping the machine further ensures work efficiency, and has the effect of collecting and uniformly treating the cleaned impurities and sludge.

[0035] Working principle: Step 1, the external water supply pipe adds water from above the annular filter block 3, and its impurities and sludge are intercepted in the annular filter block 3 by the arc filter 5. The filtered water enters the treatment interior, and then is transported to the pump station through the pump station inlet pipe 814 to supply water to the pump station. At the same time, the servo motor 81 is started to work, and the servo motor 81 drives the driving gear 83 to rotate through the rotating shaft 82. The rotation of the driving gear 83 drives the arc slider 7 to slide in the annular positioning groove 6 through the meshing outer gear ring 2. The movement of the arc slider 7 drives the arc mounting plate 8 to rotate in a circle along the annular filter block 3;

[0036] Step 2: The L-shaped fixing block 84 of the arc-shaped mounting plate 8 moves. The movement of the L-shaped fixing block 84 drives the driving block 89 to perform circular motion through the guide block 87. The driving block 89 drives the arc-shaped cleaning block 811 to perform circular motion through the cooperation of the limit rod 810. The movement of the arc-shaped cleaning block 811 cleans the impurities and sludge adsorbed on the surface of the arc-shaped filter screen 5. The cleaned impurities and sludge fall to the bottom of the conical collecting cylinder 812, and the collected impurities and sludge are discharged by opening the solenoid valve of the drain pipe 813.

[0037] Step three, when the arc cleaning block 811 needs to be replaced, hold the handle on one side of the driving block 89 and pull it. The movement of the driving block 89 drives the guide block 87 to move through the guide rod 86, so that the contraction spring 88 is stretched. At the same time, the inner wall of the driving block 89 moves away from the limit rod 810 to complete the disassembly of the arc cleaning block 811. During installation, pull the driving block 89 again to move so that it drives the guide block 87 to move through the guide rod 86. At this time, the contraction spring 88 is stretched, and the limit rod 810 is inserted into the inner wall of the driving block 89 and then the driving block 89 is released. The elastic force of the contraction spring 88 drives the driving block 89 to reset and move, thereby driving the arc cleaning block 811 to move and fit the inner wall of the annular filter block 3 through the movement of the driving block 89.
