Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device with a filter screen. Background Technology

[0002] The main purpose of wastewater treatment equipment is to treat domestic sewage and similar industrial organic wastewater to meet the requirements for reuse, enabling the resource utilization of treated wastewater. Based on summarizing advanced experiences both domestically and internationally, continuous improvements to wastewater treatment processes have promoted the rapid development of wastewater treatment equipment.

[0003] Application number CN202223521734.3 discloses a high-efficiency rural sewage treatment device. The device uses a first filter bed with a screen to remove large floating debris and other impurities for initial filtration. It then uses a second filter bed with a horizontal screen for further filtration, followed by anaerobic and aerobic treatment tanks, and finally, sedimentation in a sedimentation tank before discharge. The device has a simple structure and high treatment efficiency. A moving brush cleans the horizontal screen to prevent clogging, and brushes impurities from the screen into a scraper tank for easy cleaning. However, this design has shortcomings. The first filter bed contains a screen, which accumulates impurities over time, clogging the screen's gaps. Therefore, the screen needs to be removed, cleaned, and reinstalled. However, the first filter bed does not allow for convenient removal and installation of the screen, limiting its usability.

[0004] Therefore, we propose a wastewater treatment device with a filter screen. Utility Model Content

[0005] The main purpose of this utility model is to provide a sewage treatment device with a filter screen. The screen plate is fitted with the housing through a mounting frame and fixed by bolts. It can be removed by simply loosening the bolts without complicated tools. At the same time, the housing is connected to the first filter tank through a sealing plate. After unscrewing the self-tapping screws, the housing can be removed as a whole by pulling the handle, realizing the quick assembly and disassembly of the screen plate. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A wastewater treatment device with a filter grid includes a first filter tank, a second filter tank, and a housing. The first filter tank is connected to the second filter tank via a pipe. The first filter tank has a filter chamber inside. The top of the first filter tank has an opening for installing the housing. The top of the first filter tank also has an embedding groove communicating with the opening. A sealing plate is fixedly connected to the top of the housing. A handle is fixedly connected to the center of the upper surface of the sealing plate. The housing has a cavity communicating with the filter chamber. The inner wall of the housing near the second filter tank has a slot for installing the grid plate.

[0008] The lower part of the inner wall of the box body away from the grid plate is provided with a feeding plate. Both ends of the feeding plate are fixedly connected to the inner walls of both ends of the filter chamber. A collection chamber is provided between the feeding plate and the grid plate. A drain outlet for installing a draining net is provided on the lower part of the feeding plate near the collection chamber. An installation frame is fitted on the outer side of the grid plate.

[0009] By adopting the above technical solution, the grating plate is fitted with the slot of the box body through the mounting frame and fixed by bolts. It can be removed by simply loosening the bolts without complicated tools. At the same time, the box body is connected to the first filter tank through the sealing plate. After unscrewing the self-tapping screws, the box body can be removed as a whole through the handle, realizing the quick assembly and disassembly of the grating plate and solving the problem of cumbersome grating disassembly in traditional equipment.

[0010] Specifically, the sealing plate has movable grooves at both ends that are adapted to the fasteners, the upper parts of both ends of the fasteners are located in the movable grooves and are slidably connected to the sealing plate, and the top of the fasteners has a fastening groove.

[0011] Specifically, the mounting frame is provided with an insertion hole that matches one side of the grating plate, and the mounting frame is fixedly connected to the inside of the box by bolts.

[0012] Specifically, the mounting frame is located within the slot, and both the mounting frame and the grille are inclined.

[0013] Specifically, the sealing plate is horizontally located in the embedded groove, and the sealing plate is a horizontally arranged rectangular plate structure. A sealing gasket is fixedly glued to the outer edge of the lower end face of the sealing plate.

[0014] Specifically, the sealing plate is fixedly connected to the top of the first filter tank by self-tapping screws, and an inlet pipe is fixedly inserted into the side of the first filter tank away from the second filter tank. The discharge plate is located below the inlet pipe.

[0015] The beneficial effects of this utility model are as follows: The wastewater treatment equipment with filter screen described in this utility model has a screen plate that is fitted with the box body through a mounting frame and fixed by bolts. It can be removed by simply loosening the bolts without complicated tools. At the same time, the box body is connected to the first filter tank through a sealing plate. After unscrewing the self-tapping screws, the box body can be removed as a whole through the handle, realizing quick disassembly and assembly of the screen plate, which solves the problem of cumbersome screen disassembly in traditional equipment.

[0016] The inclined grating and mounting frame guide impurities to automatically slide into the collection chamber, reducing clogging of the grating gaps. The drain screen separates moisture from the impurities, reducing the weight and difficulty of subsequent cleaning and improving the continuous operating efficiency of the equipment. The sealing plate is embedded in the groove and has a sealing gasket at the bottom, which can effectively prevent sewage leakage in the filtration chamber. The structure is flexible and highly adaptable: the mounting frame's insertion holes can be adapted to different specifications of grating plates, and by replacing the grating plates, the filtration needs of impurities in different sewage can be met (such as adjusting the size of the grating gaps), thus expanding the applicability of the equipment.
