Description

A non-stop filter device

technical field

The utility model relates to the technical field of filtering water for agricultural irrigation, in particular to a filter device without shutdown.

Background technique

At present, the drip irrigation equipment used in Xinjiang is mainly composed of channels, gates, reservoirs, water suction pipes, water pumps, backwash filter devices, water delivery pipes, buried pipes, and drip irrigation belts. Good, but the filter effect on flocs, especially the flowers of Populus euphratica and Tamarix, the main local windbreak trees, is poor. These flocs are entangled on the filter screen of the backwashing device and gradually clogged. When the internal and external pressure of the device is unbalanced for flushing, some flocs Instead of being washed away, the lumps formed and entangled on it, resulting in waste of energy and water resources, while reducing the pressure of the water outlet, which can be reduced by 50% at most, and must be shut down for disassembly and cleaning at this time.

If it is during the busy farming season (especially in July and August when the water consumption peaks, when the local plants such as Tamarix and Populus euphratica are in flowering period, a large amount of flocculent floating matter is produced, mixed in the channel and enters the filter device with the water flow), the water source is tense, and the pump room 24-hour operation, a shutdown will cause serious losses to the entire production unit and pump room contractors. Moreover, due to the tightly entangled flocculent floating objects, it is difficult to effectively clean them in the pump room. It is often necessary to bring professional cleaning liquids such as acid and alkali solutions for corrosion and re-cleaning, which not only delays the progress of irrigation, but also wastes water resources.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

The embodiment of the utility model provides a non-stop filter device, as shown in Figure 1, the device includes: a filter cavity 3, the two ends of the filter cavity 3 are provided with a water inlet 1 and a water outlet 9; the water inlet 1 is provided with a water inlet sensor 2, and the water outlet 9 is provided with a water outlet sensor 8; the middle part of the filter cavity 3 is provided with a first filter cavity 5 and a second filter cavity 12 below it; A filter cavity partition 10 is arranged between the first filter cavity 5 and the second filter cavity 12; a filter rod 11 is arranged in the first filter cavity 5 and the second filter cavity 12; In the filter chamber 5, a first water inlet valve 4 is provided at the water inlet end, and a first water outlet valve 7 is provided at the water outlet end; the second filter chamber 12 is provided with a second water inlet valve 17 at the water inlet end (refer to the figure 3), one end of the water outlet is provided with a second water outlet valve (not shown in the figure, the structure of the water inlet valve in Fig. 3 can be referred to); The passage hatch 15 is used as a part of the cavity when the hatch is closed, and can be used to discharge the clogged impurities when it is opened. The first impurity removal passage hatch 15 is connected with the cavity by the hinge 6, and the second filter chamber 12 is provided with a second impurity removal filter. Passage cabin door 13 (the function is the same as the first impurity-removing passage hatch 15 of the first filter cavity 5 peripherals), effect and installation mode are the same as the first filter cavity.

As shown in Figure 2, a first impurity removal channel hatch 15 is also provided on the outer cavity of the first filter cavity 5, and an observation window 14 is arranged on the impurity removal channel hatch, and the first filter cavity 5 is provided with impurity removal device 18. Wherein, the impurity removal device 18 is strung on the filter rod 11, as shown in Figure 2, after opening the impurity removal channel hatch 15, the impurity removal device 18 can be slid to discharge the impurities 16 on the filter rod 11 without stopping the machine filter device. As shown in FIG. 2 , the second filter chamber 12 is also provided with a second impurity removal passage hatch 13 , an observation window, and an impurity removal device, whose functions are the same as those in the first filter chamber 5 .

When filtering with the non-stop filter device provided by the utility model, the filtering process is as follows: the water flow enters from the water inlet 1, the water flow parameters are measured by the water inlet sensor 2, the inlet valve 4 and the water outlet valve 7 are opened, and the water flow passes through the filter. When the rod 11 is used, the flocs are blocked and accumulated. In the first filter chamber 5, the filtration situation in the chamber and the accumulation of impurities 16 can be observed through the observation window 14. When the flocs accumulate to a certain extent, the water outlet The value difference between sensor 8 and water inlet sensor 2 is relatively large. At this time, open the second water inlet valve 17 and the second water outlet valve, and close the water inlet valve 4 and water outlet valve 7, empty the liquid in the cavity, and open the hatch 15. The impurity removal device 18 pushes the impurity hanging on the filter rod out of the hatch (as shown in Figure 2, moving from area A to area B), and resets to complete an impurity separation operation. When the first filter chamber 5 is performing the impurity separation operation, the second water inlet valve 17 and the second water outlet valve are opened, and the second filter chamber 12 starts to filter. That is, the first filter chamber 5 and the second filter chamber 12 work in turn to ensure that the non-stop filter device is always filtering without stopping the machine.

It should be noted here that the arrangement of the filter rods in the present invention is not limited to a fixed array, nor is it limited to a push-type waste removal method.

After installation, the no-stop filter device provided by the utility model can significantly reduce the content of flocculent suspended matter in water, reduce the working pressure of the head filter device, and can be cleaned and maintained without stopping the machine.

The cavity of the non-stop filter device provided by the utility model is made of welded stainless steel plates, the filter rod is made of nylon material, and the impurity removal push plate is made of stainless steel material. Due to the high alkalinity of water in Xinjiang, ordinary iron materials are very easy to corrode , so stainless steel is used. The valve can be electromagnetic or ball valve or butterfly valve. The sensor can be a flow sensor or a pressure sensor. Tube cleaning windows are made of ordinary tempered glass. The water inlet and water outlet valve switch operations can be manually controlled or controlled by a motor.

When the non-stop filter device provided by the utility model is used, the flow of flocs or rods can be effectively restricted when passing through the filter chamber, and the influence of plant tissues on the filter device during peak water consumption in summer can be alleviated. At the same time, the structure is simple and easy to install and maintain.

The above is only a specific embodiment of the present utility model, but the scope of protection of the present utility model is not limited thereto. Anyone familiar with the technical field can easily think of changes or changes within the technical scope disclosed by the utility model Replacement should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
