Abstract
A pressure friction type automatic spraying device is mainly used for controlling automatic water spray so as to remove and reduce dust in a belt conveyor coal conveying process. The pressure friction type automatic spraying device comprises a control valve with a water inlet and a water outlet, a switch control lever of the control valve is disposed below a belt conveyor and connected with a valve pedal, and the other end of the valve pedal is connected with a pressure friction wheel which is closely attached onto a belt. When coal is conveyed on the belt, the control valve can be switched on after the pressure friction wheel is shifted and touched by the belt, and then a water spray nozzle connected with the water outlet sprays water mist. The belt is pressed to touch the pressure friction wheel under gravity of the coal layer on the belt conveyor so as to switch on the control valve, spray dust suppression can be achieved by aid of the mechanical control principle, utilization of special switch devices such as power supplies and electric appliances are avoided, and therefore, the pressure friction type automatic spraying device is safe, reliable, fast and convenient.
Description
Technical field:
The utility model relates to a kind of pressure formula automatic sprayer that rubs, be mainly used in the belt feeder transportation coal process control automatically watering with dedusting, depositing dust.
Background technology:
Coal is producing a large amount of dust by meeting in the belt transportation, contaminated environment, and have potential safety hazard.And adopt electric equipment control watering, and brought safety problems such as explosion-proof again, bring very burden for production and use.
Summary of the invention:
The purpose of this utility model provides a kind of pressure formula automatic sprayer that rubs, and adopts mechanical control principle control atomizing de-dusting, has avoided the potential safety hazard of using power supply, electrical equipment etc. to bring.
The purpose of this utility model realizes as follows: it comprises a by-pass valve control that has water inlet and delivery port, water inlet connects pressure water source, connect shower nozzle by high-pressure rubber pipe on the delivery port, the switch control handle of the by-pass valve control of device below belt feeder connects the valve pedal, and the other end device of valve pedal is pressed the wheel that rubs.Press this pressure wheel that rubs and to open by-pass valve control, make delivery port ejection water smoke.
One support is arranged, and the support two ends have respectively by bolt and the fixing carrier base of belt feeder support, and each carrier base is fixed a sleeve that has internal thread; A screwed pole in two ends is arranged, and the two ends of pole are screwed in the internal thread hole of sleeve by screw thread respectively, and the screw that can hold out against pole is set on the sleeve outer wall, and by-pass valve control is fixed on the pole.Before the installation, unclamp the screw on the sleeve outer wall, adjust the width of the suitable belt feeder support of distance between the two stands seat, screw screw then and fix, by being bolted on the belt feeder support on the carrier base.
After the installation, make and press the wheel that rubs to be close to belt, during the belt feeder operation, when not having coal to pass through on the belt, belt does not contact presses the wheel that rubs, and by-pass valve control is in closed condition, and the anhydrous spray painting of shower nozzle goes out; When having coal to pass through on the belt, under the gravity effect of coal, compress belt and touch and dial to press the wheel that rubs, press the wheel that rubs to drive the valve pedal and open by-pass valve control, the water under high pressure circulation, the control shower nozzle sprays water smoke, falls and removes coal dust, and working face is purified.
The utility model compresses belt by coal seam gravity on the belt feeder and touches to dial and press the wheel that rubs, and opens with by-pass valve control, adopts mechanical control principle to reach the atomizing de-dusting purpose, avoids adopting special key devices such as power supply, electrical equipment, and is safe and reliable, efficient and convenient.
Description of drawings:
Fig. 1 is a front view of the present utility model.
Fig. 2 is a left view of the present utility model.
The specific embodiment:
With reference to Fig. 1, Fig. 2, a support 5 is arranged, support 5 two ends have respectively by bolt and the fixing carrier base of belt feeder support, and each carrier base is fixed a sleeve that has internal thread; A screwed pole in two ends is arranged, and the two ends of pole are screwed in the internal thread hole of sleeve by screw thread respectively, and the screw that can hold out against pole is set on the sleeve outer wall.By-pass valve control 4 devices that have water inlet 2 and delivery port 6 are arranged on support 5 poles, make by-pass valve control 4 be in the belt feeder below, the water inlet 2 of by-pass valve control 4 connects pressure water source, connect shower nozzle by high-pressure rubber pipe on the delivery port 6, the switch control handle of by-pass valve control 4 connects valve pedal 3, the other end device of valve pedal 3 is pressed the wheel 1 that rubs, housing of by-pass valve control 4 outer cup.Adjust and press the wheel 1 that rubs to be close to belt, when having coal to pass through on the belt, belt touches to dial presses the wheel 1 that rubs can open by-pass valve control 4, makes the shower nozzle ejection water smoke that is connected with delivery port 6; When not having coal to pass through on the belt, belt does not contact presses the wheel 1 that rubs, and by-pass valve control 4 is in closed condition, and anhydrous spray painting goes out.
