Abstract
The utility model discloses a push type spray gun system which comprises a supporting frame, wherein the supporting frame is rotatably provided with a screw internally; the screw is sleeved with a barrel matched with the screw; the supporting frame is provided with a motor which drives the screw to rotate and a speed reducer; a spray gun is fixedly connected with the barrel through a connecting piece; the supporting frame is provided with a sensor, the barrel is fixedly provided with a magnetic ring, the motor is controlled by a controller, and the sensor is connected with the controller. The spray gun is controlled to extend or shrink through match of the magnetic ring and the sensor, so that spraying scope is further adjusted and the denitration effect is improved. In addition, when the spray gun does not need to work, the spray gun can be retreated from a boiler to prevent the spray gun from being affected by high temperature. The system is simple in structure.
Description
Technical field
The utility model relates to a kind of pusher gun system.

Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of pusher gun system is provided, and effectively protects spray gun, extends its service life, can adjust spray regime, improves denitration effect.
For achieving the above object, the technical solution of the utility model has been to provide a kind of pusher gun system, comprise bracing frame, in described bracing frame, rotate and be provided with screw rod, on described screw rod, be arranged with the swivel nut matching with it, on described bracing frame, be provided with the motor and the reductor that drive described bolt rotary, spray gun and described swivel nut are fixedly connected by connector, on described bracing frame, be provided with sensor, on described swivel nut, be fixedly installed magnet ring, described motor is controlled by controller, described sensor is connected with described controller.
As preferably, described bracing frame comprises sleeve pipe, the two ends of described sleeve pipe are fixedly connected with respectively the first connecting plate and the second connecting plate, between the first described connecting plate and the second described connecting plate, be connected with some pull bars, some described pull bars are arranged at described sleeve pipe surrounding, the bottom of described sleeve pipe offers gathering sill along its length, and described connector slides and is arranged in described gathering sill, and described sensor setting is on the pull bar described in one of them.
As preferably, the setting of sliding mutually of described sensor and described pull bar.
As preferably, the bottom of described gathering sill is connected with the grey hairbrush of gear.
As preferably, described motor and described reductor and described the first connecting plate are fixedly connected, and the bottom of the second described connecting plate offers the perforate of passing for described spray gun.
As preferably, described magnet ring is magnet circle.
As preferably, described magnet ring and described swivel nut are fixedly connected by AB glue.
As preferably, described screw rod is horizontally disposed with.
Advantage of the present utility model and beneficial effect are: by coordinating of magnet ring and sensor, can control spray gun extends or shrinks back, then adjust spray regime, improve denitration effect, when ought not need to use spray gun work in addition, spray gun can be exited in boiler, avoid spray gun to be subject to temperatures involved, and simple in structure.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
In figure: 1, screw rod; 2, swivel nut; 3, motor; 4, reductor; 5, connector; 6, sensor; 7, magnet ring; 8, sleeve pipe; 9, the first connecting plate; 10, the second connecting plate; 11, pull bar; 12, gathering sill; 13, keep off grey hairbrush; 14, spray gun.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As Figure 1-Figure 2, a kind of pusher gun system, comprise bracing frame, in bracing frame, rotate and be provided with horizontally disposed screw rod 1, on screw rod 1, be arranged with the swivel nut 2 matching with it, on bracing frame, be provided with motor 3 and reductor 4 that drive screw 1 rotates, spray gun 14 is fixedly connected by connector 5 with swivel nut 2, wherein swivel nut 2 is aluminum alloy materials with screw rod 1 and makes, on bracing frame, be provided with sensor 6, on swivel nut 2, be fixedly installed magnet ring 7, motor 3 is controlled by controller, sensor 6 is connected with controller, bracing frame comprises sleeve pipe 8, the two ends of sleeve pipe 8 are fixedly connected with respectively the first connecting plate 9 and the second connecting plate 10, between the first connecting plate 9 and the second connecting plate 10, be connected with four pull bars 11, four pull bars 11 are arranged at sleeve pipe 8 surroundings, the bottom of sleeve pipe 8 offers gathering sill 12 along its length, connector 5 slides and is arranged in gathering sill 12, sensor 6 is arranged on one of them pull bar 11, magnet ring 7 is magnet circle, magnet ring 7 is fixedly connected by AB glue with swivel nut 2.
Without diagram, settings of sliding mutually of sensor 6 and pull bar 11, can adjust the displacement of spray gun 14 then by adjustment sensor 6 and pull bar 11 position, can, for adjustment spray regime, improve denitration effect.
As shown in Figure 2, gathering sill 12 bottom is connected with the grey hairbrush 13 of gear, by keeping off grey hairbrush 13, stops that external dust enters in sleeve pipe 8 from gathering sill 12, avoids affecting coordinating of swivel nut 2 and screw rod 1, avoids the situation appearance that causes swivel nut 2 and screw rod 1 to kill.
As shown in Figure 1, motor 3 and reductor 4 and the first connecting plate 9 are fixedly connected, and the second connecting plate 10 bottom offers the perforate of passing for spray gun 14.
