Description

Manual abluent filter system

Technical Field

The utility model belongs to the technical field of agricultural irrigation, in particular to manual abluent filter system.

Background

In irrigation systems, water delivery filters are divided into manual cleaning filter systems and automatic backwashing filter systems. After the filter works for a period of time, if the filtered impurities are accumulated too much, the water passing amount of the filter is reduced, and the pressure of the system is reduced, the automatic backwashing filter automatically starts a backwashing function to flush the impurities and discharge the impurities from a sewage discharge outlet. For reasons of cost, the manual cleaning filter apparatus has no automatic backwashing control unit, which may include a two-position three-way valve for electromagnetic control and a filtering unit body for automatic backwashing. The filter system for manual washing is provided with the filter unit body which is manually cleaned, and after the filter works for a period of time, impurities intercepted by the filter are accumulated on the surface of the filter element of the filter, so that the water flow rate of the filter and the system pressure can be seriously influenced, and the water consumption and the pressure of an irrigation system are adversely affected. At this time, the filter needs to be manually disassembled and manually cleaned. In order to prevent that the water of sunlight direct incidence in the filter from breeding the alga and causing the jam, the filter shell is black opaque usually, and the inside condition can't be directly seen to the manual work, the manometer of filter system installation, and the operation workman can't look over very well and calculate the pressure differential, often leads to the filter to block up the back, and the operation workman can't know, can not in time wash the filter, has influenced irrigation system's normal use.

SUMMERY OF THE UTILITY MODEL

The utility model provides a manual abluent filter system, aim at solve the manual abluent filter system who uses among the current agricultural irrigation, the problem that is difficult to the smooth operation in the practice.

One of the embodiments of the utility model provides a manual abluent filter system for agricultural irrigation. The filter system comprises a filter, a filter body and a filter cover,

a water inlet pipe;

a water outlet pipeline;

a plurality of filter unit bodies which are parallelly bridged between the water inlet pipeline and the water outlet pipeline, wherein the filter unit bodies adopt a manual cleaning mode; wherein

Each filter unit body is communicated with a water inlet pipeline through a water inlet valve,

each filter unit body is communicated with a water outlet pipeline through a water outlet valve;

a water inlet pressure sensor is arranged on the pipe wall of the water inlet pipeline,

a water outlet pressure sensor is arranged on the pipe wall of the water outlet pipeline,

the water inlet pressure sensor and the water outlet pressure sensor are respectively coupled with a feedback controller, and the feedback controller is used for responding to the pressure output values of the water inlet pressure sensor and the water outlet pressure sensor, calculating the pressure difference value between the water inlet pipeline and the water outlet pipeline and outputting the difference value.

The beneficial effects of the utility model include:

the filter unit bodies connected in parallel are communicated with the water inlet pipe and the water outlet pipe, so that the water flow and the filtering pressure of the filter are balanced to the maximum extent, and the detection accuracy of the pressure difference between the water inlet pipeline and the water outlet pipeline is ensured.

2, a feedback controller and a buzzing alarm lamp are added in the filter system for manual cleaning, so that the filter cleaning time is reminded.

Detailed Description

Embodiment one, as shown in fig. 1. A manually cleaned filter system for use in agricultural irrigation. The filter system includes: a water inlet pipe; a water outlet pipeline; and the filter unit bodies are parallelly bridged between the water inlet pipeline and the water outlet pipeline and are cleaned manually. Wherein, each filter unit body is communicated with the water inlet pipeline through the water inlet valve, and each filter unit body is communicated with the water outlet pipeline through the water outlet valve. The pipe wall of the water inlet pipeline is provided with a water inlet pressure sensor, and the pipe wall of the water outlet pipeline is provided with a water outlet pressure sensor. The water inlet pressure sensor and the water outlet pressure sensor are respectively coupled with a feedback controller, and the feedback controller is used for responding to the pressure output values of the water inlet pressure sensor and the water outlet pressure sensor, calculating the pressure difference value between the water inlet pipeline and the water outlet pipeline and outputting the difference value. The beneficial effects of this embodiment are that, adopt a plurality of filter unit bodies of parallel cross-over connection to communicate inlet tube and outlet pipe, furthest balancing the water flow and the filtration pressure of crossing of filter, guaranteed the detection accuracy to the pressure differential between inlet channel and the outlet conduit.

In the second embodiment, as also shown in fig. 1, based on the first embodiment, the feedback controller is coupled to an alarm, and the feedback controller triggers the alarm according to an alarm threshold set by the pressure difference between the water inlet pipe and the water outlet pipe. The alarm can adopt a buzzing alarm lamp, and can emit high-brightness lamp flashing while emitting high-decibel sound.

In a third embodiment, on the basis of the first embodiment or the second embodiment, when the alarm is started for a preset time period, the pressure difference between the water inlet pipeline and the water outlet pipeline is not changed all the time, and the alarm is not manually released, the control feedback device sends a warning message to a preset mobile terminal. And the feedback controller obtains the pressure values of the water inlet pipeline and the water outlet pipeline through detection, sets and judges the pressure difference delta P, and starts a feedback program and a starting buzzing alarm lamp. The beneficial effects of this embodiment are that, add a feedback controller and buzzing alarm lamp in manual abluent filter system, feedback controller real-time detection advances, outlet pipe pressure differential, and when the pressure differential reached the setting value, buzzing alarm lamp sounded and the light was reported to the police, and the workman sees or can in time carry out cleaning work to the filter after hearing. When no operator is on site, the buzzing alarm lamp continuously works for a set time, and the feedback controller can send information to the set mobile phone to inform a user of the mobile phone of the situation and remind the user to clean the filter system in time. In the present embodiment, the determination of the alarm pressure difference by the alarm and the setting procedure of the alarm time are already known techniques.

It is worth noting that while the foregoing has described the spirit and principles of the present invention with reference to several specific embodiments, it is to be understood that the present invention is not limited to the disclosed embodiments, nor is the division of aspects, which is for convenience only as the features in these aspects cannot be combined.
