Technical Field

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

[0002] The filter tanks used to filter wastewater or waste liquid at garbage transfer stations generally filter by installing a filter screen or filter module inside the tank. If the mesh of the filter screen is too small, it will be difficult to clean if it is blocked. If the filter module is blocked, 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 into the interior for cleaning, which is very inconvenient. It is also difficult to clean the interior 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 top of the tank flush with the ground. It is inconvenient to clean the filter components, and the line of sight and the operable depth are limited. The requirements for cleaning tools are also high, which increases the difficulty of cleaning. Utility Model Content

[0005] The beneficial effect of the filter tank with a liftable filter tray of the present invention is that the filter tray can be raised to a suitable height above the ground by a liftable mechanism, making it easy to clean. Specifically, a movable filter tray is provided below the liquid inlet in the filter tank, and a special cleaning port is provided. A liftable support platform is provided below the cleaning port. When the filter tray needs to be cleaned, it can be moved horizontally above the support platform. The lifting support platform can be used to raise the filter tray to a height above the ground for easy cleaning. Then, manual or mechanical cleaning can be performed to facilitate cleaning operations. After cleaning, it can be lowered to the filtering height in the tank and then moved horizontally to below the liquid inlet by a sliding guide component to continue filtering waste liquid.

[0006] To facilitate the docking of the filter tray and the support platform, the bottom of the filter tray cooperates with the support platform for support. A limit frame is provided at the bottom of the filter tray, and the limit frame and the outer edge limit sleeve of the support platform. When the filter tray is translated to the top of the support platform and aligned with the limit frame, the raised outer edge of the support platform is just limited by the limit frame sleeve.

[0007] To facilitate lifting the filter tray, the lifting mechanism includes a vertically arranged sliding sleeve, the top of which is fixed to the support platform, the lower end of which is fixed with a sleeve seat, and the sleeve seat is symmetrically provided with two sets of rodless cylinders in the radial direction.

[0008] To facilitate the guiding installation of the sleeve, a central guide shaft is provided inside the sleeve, a base plate is fixed to the bottom of the central guide shaft, the base plate is fixed to the bottom wall of the filter tank, the upper end of the central guide shaft guide extends to the inside of the sleeve, and connecting plates are connected on both sides of the radial direction of the sleeve seat. The rodless cylinder includes a cylinder barrel and a slider, and a connecting seat is provided on the side corresponding to the slider and the connecting plate, and the connecting seat is fixedly connected to the connecting plate.

[0009] To facilitate the installation and connection of the rodless cylinder, a cylinder fixing plate parallel to the support platform is fixed on the upper end of the cylinder barrel of the rodless cylinder. A guide hole for the sliding sleeve to pass through is provided in the center of the cylinder fixing plate. Four support rods are symmetrically provided at the four corners of the cylinder fixing plate. The support rods and the bottom of the cylinder barrel are fixed on the base plate.

[0010] To facilitate the sliding and translation of the filter tray, the sliding guide component includes a guide rail fixedly arranged on the inner wall of the filter tank. The filter tray is hoisted to the guide rail through a tray hanging frame. The tray hanging frame includes a bottom frame and a side frame. The bottom frame is used to support the filter tray. The top of the side frame is equipped with a guide wheel corresponding to the guide rail.

[0011] In order to facilitate limiting the extreme positions of the filter tray in two translation directions, stoppers for limiting the position of the filter tray are respectively provided on both sides of the lengthwise direction of the guide rail.

[0012] To facilitate the separation of solid waste of varying sizes and specific gravities, the filter tray is divided into a bottom sedimentation collection area and an upper filtration area. The sidewalls of the filtration area are provided with several filtration holes; the sedimentation collection area of ​​the filter tray is in the shape of an inverted trapezoid. When solid waste of varying sizes and specific gravities mixed with the wastewater enters the filter tray, the heavier solid waste sinks directly into the tray, while the lighter solid waste floats in the upper filtration area. Liquid flows into the tank through the filtration holes, while the solids are trapped within the tray. This tray structure significantly reduces obstruction of the filter holes by the solid waste and improves filtration speed. BRIEF DESCRIPTION OF THE DRAWINGS
