Description

A low-cost anti-scaling horizontal pre-filter

technical field

The utility model belongs to the technical field of filters, in particular to a low-cost anti-scaling horizontal pre-filter.

Background technique

In the prior art, with the improvement of people's living standards, people generally realize that it is necessary to add a purification device to the household water source to filter large particles such as sediment, rust, insect eggs, bloodworms, etc. in the tap water.

There are mainly the following types of pre-filters on the market:

1. The main disadvantages of the laminated filter are: incomplete washing of impurities, uneven filtration accuracy, and no sewage outlet.

2. The main disadvantages of the flushing filter are: if the water quality is poor, or the consumer's habits are not good, the filter element is easily blocked, not only the small impurities cannot be washed out, but are embedded deeper in the filter element. If it is tighter, it is easy to cause secondary pollution. You can only open the housing to take out the filter element and scrub it with a toothbrush. The operation is more cumbersome.

3. The main disadvantages of the siphon filter are: complex product structure, incomplete flushing, such as poor water quality, some impurities embedded deeper and tighter in the filter element, and finally the filter element is blocked, causing secondary pollution. It is very difficult to maintain, and the filtration accuracy of most siphon products produced is above 50 microns.

4. Backwashing filter, although the filtering effect is better, but its cost is high, the structure is complicated, and the cleaning is cumbersome. If backwashing cannot remove the intercepted matter blocked in the filter mesh hole, it is necessary to open the filter bottle to take out the filter mesh, and use a wool Brush, air gun and other tools to clean up.

To sum up, the cost of the pre-filter in the prior art is relatively high, and it is difficult to popularize it in every household. In addition, these filters are large in size, and not all locations can be installed; and the city's water supply pipes are old, and impurities such as rust and sediment in the pipes will not only cause brown water and damage to water equipment, but also damage the human body. Produce harm; When drinking, people generally adopt the way of boiling, but this method can not get rid of insoluble solid matter impurity and harmful chemical substance. Therefore, the pre-filter also needs to reduce costs and popularize more users.

Further, the water inlet, water outlet, and sewage outlet are provided with external threads.

Further, a water inlet filter is installed at the water inlet.

Further, the chamber on the water inlet side is the antiscalant chamber two, filled with antiscalant.

Further, at the sewage outlet, a plurality of through holes are provided on the pipe wall of the filter body.

Further, the filter body is made of PC, and the water inlet filter, outlet filter and intermediate filter are stainless steel filters.

Further, a pagoda ball valve is connected to the sewage outlet.

The beneficial effects of the utility model:

1. The pre-filter provided by the utility model has a simple structure and a small volume, and is suitable for use in more places; the production cost is low, and it is convenient for market promotion;

2. The utility model is easy to install, does not require professionals and professional tools, and can be used only through screw connection and manual tightening in the water pipe;

3. The structural design of the filter support plate, the middle filter and the filter card board makes the water flow smooth and the resistance is small.

4. There is an antiscalant chamber inside the filter body, and the position is set reasonably, which is convenient for the replacement of the antiscalant and the later maintenance; in addition, when the pagoda ball valve is installed at the sewage outlet, the impurities can be discharged from the pagoda ball valve .

To sum up, the utility model provides a low-cost anti-scaling horizontal pre-filter with low production cost, convenient installation and positive market prospect.
