Description
Technical field
The utility model relates to filtration art, is specifically related to a kind of cleaning filter warning device.
Background technology
The normal use of filter comprises filters and cleans two links, cleans and directly affects filter effect.When filter cleans, depend on filter intake-outlet pressure differential, the measuring method of pressure differential mainly contains two kinds at present, method one is to read by being arranged on the Pressure gauge of filter intake-outlet, its shortcoming is to need operating personnel to pay close attention in real time pressure gauge reading, if work carelessness there will be cleaning not in time, cause filter to damage; Method two is to read by differential pressure pickup, and its shortcoming is generally will be used in combination with the intelligence control system such as PLC, and differential pressure pickup and PLC price are more expensive, are not easy to promote.Therefore, design a kind of cleaning filter warning device cheap, that effect is good and accurately reminding user cleans significant.
Summary of the invention
The utility model for the problem that solves current Pressure gauge and differential pressure pick-up and in use occur provide a kind of use simple, the life-span is long and the cheap cleaning filter warning device of cost of manufacture.
The technical solution of the utility model is: cleaning filter warning device, it is characterized in that mainly by cavity, piston, leading screw, spring, sealing ring, detection bodies, waterproof approach switch, buzzer and electric power generating composition, wherein inside cavity is separated into two independently chambers by piston, this piston is slidably matched by piston ring and cavity seal, the middle part of piston is assigned on leading screw by sealing ring cunning, the two ends of this leading screw extend to respectively the sidewall outside of cavity, the two ends of leading screw are helicitic texture, by the nut matching with screw thread, leading screw is fixed on the sidewall of cavity, the middle part of leading screw is smooth stainless steel round bar, on the leading screw of piston both sides, be arranged with respectively identical spring, described piston one side is fixed with detection bodies, the cavity wall relative with detection bodies is provided with waterproof approach switch, this waterproof approach switch is connected with buzzer with power supply respectively by wire, at two, independently below chamber, be respectively equipped with spiral interface.
The utility model compared with prior art has the following advantages: the variation promotion piston by filter intake-outlet pressure moves, when detection bodies contact waterproof approach switch, circuit is connected, the timely reminding user of buzzer warning cleans, and has both the advantages such as easy to use and cost of manufacture is low, sensitivity is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Drawing explanation: 1, cavity, 2, piston, 3, leading screw, 4, spring, 5, sealing ring, 6, detection bodies, 7, waterproof approach switch, 8, buzzer, 9, power supply, 10, piston ring, 11, nut, 12, filter, 13, water inlet, 14, delivery port, 15, flexible pipe.
The specific embodiment
Describe by reference to the accompanying drawings embodiment in detail.Cleaning filter warning device, mainly by cavity 1, piston 2, leading screw 3, spring 4, sealing ring 5, detection bodies 6, waterproof approach switch 7, buzzer 8 and power supply 9 form, wherein cavity 1 inside is separated into two independently chambers by piston 2, this piston 2 is slidably matched by piston ring 10 and cavity seal, the middle part of piston 2 is assigned on leading screw 3 by sealing ring 5 is sliding, the two ends of this leading screw 3 extend to respectively the sidewall outside of cavity 1, the two ends of leading screw 3 are helicitic texture, by the nut 11 matching with screw thread, leading screw 3 is fixed on the sidewall of cavity 1, the middle part of leading screw 3 is smooth stainless steel round bar, on the leading screw of piston 2 both sides, be respectively equipped with identical spring 4, described piston 2 one sides are provided with detection bodies 6, cavity 1 sidewall relative with detection bodies 6 is provided with waterproof approach switch 7, this waterproof approach switch 7 is connected with buzzer 8 with power supply 9 respectively by wire, at two, independently below chamber, be respectively equipped with spiral interface, this spiral interface is connected with delivery port 14 with the water inlet 13 of filter 12 respectively by flexible pipe 15, wherein delivery port 14 is connected on the spiral interface of chamber below of waterproof approach switch 7 one sides, while just starting to filter, the pressure of chamber both sides is the same, the centre position of piston 2 in cavity 1 inside, along with the variation of filter 12 water inlets 13 with delivery port 14 pressure reduction, the pressure of two chambers changes, piston 2 starts mobile, when detection bodies 6 touches waterproof approach switch 7, circuit is connected, buzzer 8 is reported to the police.
The course of work of the present utility model is: the filtration initial stage, the active force of two springs 4 is identical, piston 2 horizontal direction force balances, thereby mediate, along with filtration time is passed, filter 12 stopping states constantly increase the weight of, chamber, the left side is connected with water inlet 13, pressure constantly increases, piston 2 left side pressure are obviously greater than the right pressure, under pressure differential effect, current promotion piston 2 moves right, the detection bodies 6 that is arranged on piston 2 tops moves near waterproof approach switch 7 and while contacting with waterproof approach switch 7, alarm circuit is connected, the timely filter rinsed of buzzer 8 warning reminding user.
More than show and described basic principle of the present utility model; principal character and advantage; do not departing under the prerequisite of the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall into claimed scope of the present utility model.
