Description

A high-efficiency water purification V-shaped filter

technical field

The utility model relates to a water treatment facility, in particular to a high-efficiency water purification V-shaped filter tank.

Background technique

V-shaped filter is a form of fast filter, named after the shape of the water inlet tank is V-shaped, also known as uniform filter material filter (the filter material adopts homogeneous filter material, that is, average particle size filter material), It is also called six-valve filter because there are six main valves on various pipelines, and a drainage system with a long-handle filter head bottom plate is adopted at the bottom, and there is no need for a gravel support layer. The V-shaped water inlet tank and drainage tank are respectively set on both sides of the filter tank. The tank can develop along the long direction, the water distribution is uniform, the backwashing effect is good, and the water volume and power consumption of backwashing are greatly saved. The particle size distribution in the direction is basically uniform, the filter material layer does not expand during the backwashing process, and hydraulic grading does not occur, ensuring deep pollution interception and high dirt-holding capacity of the filter layer. At present, the V-type filter has the following problems: (1) The area of the single pool is larger than that of the ordinary filter on average, but it is not fully utilized, because the drainage tank in the middle occupies a large part of the area, resulting in the actual filtration area than the single The pool area is small; (2) The conventional V-type filter is accompanied by surface sweeping during the entire flushing process, and the water consumption is relatively large.

Contents of the invention

In order to solve the above technical problems, the utility model provides a high-efficiency water purification V-shaped filter tank without the H-shaped drain tank in the middle of the filter tank.

The technical solution adopted by the utility model is: a high-efficiency water purification V-shaped filter tank, including a tank body, a water inlet system, a filter system, a backwash system, a surface cleaning device, and a drainage system, and is characterized in that: the pool The body is provided with a water inlet system and a surface cleaning device. The water inlet system includes a water inlet main pipe, a water inlet valve and V-shaped grooves located on both sides of the pool body. The water inlet valve is set on the water inlet main pipe. , the surface cleaning device includes water inlet regulating valves arranged at the water inlets of the V-shaped grooves on the left and right sides and several small water distribution holes arranged in the V-shaped grooves. On the two water inlet branch pipes, a filter system is provided in the pool body, the filter system includes a filter material layer, a filter material plate and a long handle filter head installed on the filter material plate, and the drainage system includes a drainage gate, A drainage channel and a water outlet valve, the drainage channel is arranged outside the pool body and communicated with the pool body through a drainage gate, the water outlet valve is set on the drain pipe at the bottom of the pool body for the filtered water, and the bottom of the pool body is installed There is a backwash system, and the backwash system includes a recoil inlet pipe and a recoil air pipe provided at the bottom of the pool. The recoil inlet pipe is provided with a control valve and one end of which is connected to the drain pipe, and the recoil air pipe is independently set A control valve is installed at the bottom of the pool.

The filter material layer is a double-layer homogeneous filter material layer, the upper layer is a lightweight filter material layer with a large particle size and a small specific gravity, and the lower layer is a heavy filter material layer with a small particle size and a large specific gravity. The heavy filter material adopts quartz sand, and the light filter material has a larger particle size than the heavy filter material, which has strong dirt holding capacity, high filter material utilization rate, and easy backwashing without running out of material, saving backwashing water consumption.

The drainage gate is a regulating gate, which is located at the bottom of the V-shaped groove on both sides and embedded in the pool wall. It is opened from top to bottom by electric control, and the opening can be adjusted according to the drainage of sewage after surface cleaning. Using the drainage gate can save surface Sweeping water consumption.

Both the water outlet valve and the water inlet valve are pneumatic regulating valves.

The beneficial effects of the utility model are:

1. The double-layer filter layer structure improves the filtration rate and prolongs the filtration cycle, and the effluent water quality, interception capacity and depth have also been significantly improved. The light and heavy materials can make it difficult to mix with each other and affect the filtration during backwashing In some cases, the water yield of the double-layer filter is higher than that of the single-layer filter.

2. Through the use of drainage gates to discharge sewage, the middle H tank in the conventional V-shaped filter structure is removed, the difficulty and cost of civil construction of the V-shaped filter are reduced, the effective filtration area of the filter is increased and the water consumption for surface cleaning can be saved. .
