Abstract
Description
Technical Field
[0001] This utility model relates to the field of shallow sand filters, specifically a shallow sand filter. Background Technology
[0002] A side-stream filter, also known as a shallow sand filter, is mainly used for filtering circulating water, water supply, and wastewater in industrial applications. HGBMF's media filtration system utilizes deep media to effectively remove particulate matter and reduce turbidity. If specific filter media, such as activated carbon or zeolite, are installed, it can also adsorb and remove corresponding organic matter and ions. The fluidization device in the system can fluidize the filter media, remove contaminants trapped on the media, and discharge them for thorough cleaning.
[0003] However, it still has some drawbacks. For example, when the existing shallow sand filter is running, the internal water collection device and other equipment will shake. If the shallow sand filter is too high, it may tip over during operation. In addition, this kind of machine is relatively bulky and requires more manpower to transport.
[0004] To address the aforementioned problems, this application proposes a shallow sand filter. Utility Model Content
[0005] The purpose of this utility model is to provide a shallow sand filter to solve the problems mentioned in the background art, such as the shallow sand filter being too high and potentially tipping over during operation, and the machine being relatively bulky and requiring more manpower for transportation.

The front of the filter body is fixedly connected to the control box, and the filter body is movable above the interior of the filter protection device. The top pipe is fixedly connected to the top of the filter body. The filter protection device facilitates the lifting and lowering of the filter body, preventing it from tipping over during operation due to excessive height. It also features locking casters for easy movement and transportation, and has good application prospects.
[0007] Preferably, the control box has an observation window installed on the front, the filter valve is fixedly connected to the surface of the top pipe, and a bottom pipe is installed below the filter body, with one side of the bottom pipe fixedly connected to the water inlet.
[0008] Preferably, a lifting bracket is fixedly connected to the surface of the filter body, and multiple sets of the lifting bracket are provided. The upper part of the filter body is fixedly connected to the loading port. A lifting main body groove is opened inside the filter protection device. Pipe lifting grooves are opened on both sides of the lifting main body groove, and two sets of pipe lifting grooves are provided.
[0009] Preferably, the filter protection device is fixedly connected to a locking caster wheel at the bottom, and multiple sets of locking casters are provided. The bottom pipe moves inside the pipe lifting groove, and the filter body moves inside the lifting body groove.
[0010] Preferably, the filter protection device is equipped with a hydraulic device, and the hydraulic device is provided in multiple sets. A telescopic rod is movable above the hydraulic device, and a connecting plate is fixedly connected above the telescopic rod. The connecting plate is fixedly connected to the bottom of the support bracket.

When the filter protection device is running, the entire filter body can be moved and transported using the locking casters of the filter protection device. It can also be locked in position during use. The hydraulic device inside the filter protection device drives the upper lifting bracket to rise and fall through the lifting telescopic rod. The lifting bracket then drives the filter body to rise and fall, which can prevent the filter body from being too tall and tipping over during operation. The filter protection device can also provide the ability to raise the filter body when necessary.
