Suspension type filter

Abstract

The invention discloses a suspension type filter. The suspension type filter comprises a fixing frame (2), wherein a float (1) is arranged on the fixing frame (2). The suspension type filter is characterized in that at least a driving mechanism (8), a water collecting tank (10) and a filtering device are arranged on the fixing frame (2); the driving mechanism (8) is arranged on a bracket (5) which is hinged to the fixing frame (2); a balance spring (4) is arranged between the bracket (5) and the fixing frame (2); the driving mechanism (8) and the filtering device are in transmission by a transmission chain (7); the water collecting tank (10) is arranged behind the filtering device, the upper part of the water collecting tank (10) is in an arc shape, and the lower part of the water collecting tank (10) is provided with an inverted n-shaped impurity collecting tank (9); the impurity collecting tank (9) is provided with an impurity discharge opening (11), and the impurity discharge opening (11) is used for discharging impurities to the water flow direction.

Description

technical field [0001] The invention belongs to the field of agricultural irrigation and relates to a filter, in particular to a suspension filter. Background technique [0002] Water resources are very precious, and water saving has become the trend of sustainable development of industry and agriculture. In our country, water resources are very scarce, and the per capita water resource share is only a quarter of the world's average level, and agriculture is a large water user. Therefore, it is imperative to accelerate the development of agricultural water conservation, and the rapid development of micro-irrigation technology requires Advanced filtering equipment is compatible with it. Among them, filtering equipment is very important equipment. [0003] At present, widely used filters, such as Chinese patents CN202270401U and CN201565186U, are all self-cleaning filters. Although the self-cleaning of the filter screen can be realized, the actual use has the following probl...

Problems solved by technology

[0003] At present, widely used filters, such as Chinese patents CN202270401U and CN201565186U, are all self-cleaning filters. Although the self-cleaning of the filter screen can be realized, the actual use has the following problems: 1. It must be fixed on a fixed 2. The working state needs to use the water pump to realize the water inlet and outlet of the filter; 3. There are special requirements for the filtered water source, for example, the water in the filtered water channel cannot work for a long time, mainly the working water pump and the filter screen The cleaning does not meet the actual requirements

[0005] 1. The filter cartridge is driven by a motor. In actual use, the rack will shake in the water, causing the motor to fail to drive the filter cartridge to rotate normally, reducing work efficiency;

[0006] 2. Larger impurities in the channel, such as branches, dirt, etc., will be stuck on the float, which will increase the difficulty of manual cleaning, and will also cause the entire filter to be overloaded;

[0007] 3. Since the filter cartridge is soaked in water for a long time, the transmission problem between the motor and the filter cartridge cannot be solved well. After working for a long time, there will be slipping or rusting.
