Description

Technical Field

[0001] The utility model relates to the technical field of waste liquid treatment equipment, in particular to a filter tank with double filter trays. Background Art

[0002] The filter tanks used to filter wastewater or waste liquid at garbage transfer stations generally filter by installing filter components such as filter screens or filter modules inside the tank. If the mesh of the filter screen is too small, it will be difficult to clean if it becomes clogged. If the filter module becomes clogged, it will also be difficult to clean. In addition, when cleaning the aforementioned filter components, it is necessary to disassemble the filter components or reach inside to clean them, which is very inconvenient. It is also difficult to clean the inside thoroughly. Especially for filtering treatments with a large amount of solid waste, the filter components need to be cleaned frequently to ensure the efficiency of the filtering treatment. When installing large filter tanks, in order to achieve rational use of the space in the garbage transfer station, the tank body is generally installed in a pit below the ground, with the tank top flush with the ground. It is inconvenient to operate when cleaning the filter components, and the line of sight and the operable depth are both limited. The requirements for cleaning tools are also high, which increases the difficulty of cleaning work. The filtration operation has to stop and wait while the filter tray is cleaned. On the one hand, it causes the waste liquid to accumulate on site and cannot be filtered in time for subsequent treatment. On the other hand, it also reduces the working efficiency of the filter tank. Utility Model Content

[0018] like Figures 1 to 4The figure shows a filter tank 1 with two filter trays according to the present invention, comprising a rectangular filter tank 1. The top wall of the filter tank is provided with a liquid inlet 3 (or 3'), a liquid extraction port 2, and several monitoring interfaces 5. Two liquid inlets are symmetrically arranged along the length of the filter tank, with a cleaning port 4 provided between or between the two liquid inlets. A filter tray 6 is provided within the corresponding filter tank 1 below each liquid inlet 3 (or 3'). A guide translation mechanism is provided between the filter tray 6 and the side wall of the tank body. Each filter tray 6 can be translated along the guide translation mechanism from the liquid inlet or below to below the cleaning port 4, facilitating cleaning of the filter tray 6. During field use, the liquid inlet 3 (or 3') is connected to the liquid outlet of waste liquid transport equipment. The monitoring interfaces 5 can be connected to, but are not limited to, a liquid level gauge, a pressure gauge, and a thermometer, depending on monitoring needs. The liquid extraction port is connected to a liquid extraction and drainage pipeline. When the liquid level in the tank reaches a certain height, the liquid extraction and drainage pipeline is opened to drain the liquid.

[0019] Because large filter tanks are generally installed in pits, the height of the tank top is basically flush with the ground or slightly higher than the ground. When cleaning the filter tray, in order to facilitate the cleaning construction, the height of the filter tray needs to be raised. Therefore, in the utility model, a lifting mechanism 8 for supporting the lifting and lowering filter tray 6 is provided on the lower side of the cleaning port 4, and a support platform 801 is provided horizontally on the top of the lifting mechanism 8; the filter tray 6 is hoisted by a tray hanging frame 9, and the tray hanging frame 9 includes a bottom frame 901 and a side frame 902. The bottom frame 901 is used to support the filter tray 6, and the side frames 902 correspond to the two ends of the filter tray 6 in the length direction. When the filter tray 6 is translated to above the support platform 801, the support platform 801 can be lifted by the lifting mechanism 8 to increase the height of the filter tray 6.

[0020] To facilitate the translation of the filter tray 6, the sliding guide component includes a guide rail 7 fixedly arranged on the inner wall of the filter tank 1, and a guide wheel 10 is provided at the top of the side frame 902 of the tray hanging frame corresponding to the guide rail 7. The guide rail 10 is provided with a stop block for limiting the position of the filter tray 6 at the docking positions on both sides of the translation stroke of each filter tray 6 in the length direction.

[0021] To facilitate the docking of the filter tray 6 with the support platform 801, the bottom of the filter tray 6 cooperates with the support platform 801 for support. A limit frame 601 is provided at the bottom of the filter tray 6. The limit frame 601 and the outer edge of the support platform 801 are limited. When the filter tray 6 is translated to the top of the support platform 801 and aligned with the limit frame, the outer edge of the support platform 801 is raised and is just limited by the limit frame 601.

[0022] To facilitate the lifting of the support platform 801, the lifting mechanism includes a vertically arranged sleeve 808, the top of the sleeve 808 is fixed to the support platform 801, and the lower end of the sleeve 808 is fixed with a sleeve seat, and two groups of rodless cylinders 802 are symmetrically provided in the radial direction of the sleeve seat. The inner sliding sleeve of the sleeve 808 is provided with a central guide shaft 806, and the bottom of the central guide shaft 806 is fixed with a base plate 807, which is fixed to the bottom wall of the filter tank 1. The upper end of the central guide shaft 806 guides and extends to the inside of the sleeve 808. Connecting plates 805 are connected on both sides of the sleeve seat in the radial direction. The rodless cylinder 802 includes a cylinder barrel and a slider 803. The slider 803 is provided with a connecting seat 804 on the side corresponding to the connecting plate 805. The connecting seat 804 and the connecting plate 805 are fixedly connected by a number of bolts and nuts.

[0023] To facilitate the fixed installation of the rodless cylinder 802, a cylinder fixing plate 810 is fixed on the upper end of the cylinder barrel of the rodless cylinder 802 and is parallel to the support platform 801. A guide hole is provided in the center of the cylinder fixing plate 810 for the sliding sleeve 808 to pass through. Four support rods 809 are symmetrically provided at the four corners of the cylinder fixing plate 810. The support rods 809 and the bottom of the cylinder barrel are fixed on the base plate 807.

[0024] To facilitate the separation of solid waste of varying specific gravities from liquid, filter tray 6 is divided into a bottom sedimentation collection area 602 and an upper filtration area 603. The sidewalls of filtration area 603 are provided with a number of filtration holes 604. To facilitate the sedimentation and separation of heavier solid blocks, filtration tray 6's sedimentation collection area 602 is designed in an inverted trapezoidal shape. When solid waste of varying sizes and specific gravities mixed with the waste liquid enters filter tray 6, the heavier solid waste sinks directly into the tray, while the lighter solid waste floats in the upper filtration area. Liquid flows through filtration holes 604 into the tank, trapping the solids within the tray. This tray structure significantly reduces obstruction of the filter holes by the solid waste and improves filtration speed.

[0025] The filter tank with double filter trays of the present invention has a double tray structure. During use, the two trays can be used for simultaneous filtering according to the amount of waste liquid to be processed, or a single tray can be used for filtering, with the other tray being a spare. When the solid waste in the filter tray needs to be cleaned, the filter tray 6 and the tray hanging frame 9 can be moved horizontally along the guide rail 7 to the top of the cleaning port with the help of a hook-pull tool, either manually or by using an on-site power device. Because a block is provided on the guide rail 7 facing the cleaning port 4 of the filter tray 6, when the filter tray 6 reaches the position directly below the cleaning port, the guide wheel 10 is stopped by the block, and then the lifting mechanism 8 is started, and the support platform 801 lifts the filter tray 6 upward to a predetermined height, making it convenient for the operator to clean the solid waste in the tray; after cleaning, the support platform 8001 falls, and the filter tray 6 descends And it falls on the tray hanging frame 9, pushes the filter tray to the bottom of the liquid inlet and is blocked by another limiting block below the liquid inlet to continue to filter the liquid; the two filter trays 6 of the utility model can be alternately translated to the bottom of the cleaning port for solid waste cleaning. When one tray is cleaning, the other can continue to filter the liquid, realizing continuous filtration without stopping during cleaning; the other two trays can be used alternately, or they can be used at the same time to filter the liquid separately, which greatly improves the filtration processing capacity of the waste liquid per unit time, and realizes that the filtration of the filter trays can be cleared without stopping, and also greatly improves the filtration capacity and filtration efficiency.
