Abstract
The invention discloses an electric telescopic spray gun. The electric telescopic spray gun comprises a spray nozzle and a spray gun barrel. The spray gun barrel is of a hollow structure, and the head of the spray gun barrel is connected with the spray nozzle. The tail of the spray gun barrel is provided with a water inlet and an air inlet. An electric push rod is arranged on the spray gun barrel. One end of the electric push rod is fixed to the spray gun barrel through a clamp piece, and the other end of the electric push rod is connected with a driving motor. The driving motor is connected with a sliding base and fixed to the spray gun barrel through a bracket. According to the electric telescopic spray gun provided by the invention, the electric push rod, the driving motor and the sliding base are additionally arranged on the spray gun barrel to drive the spray gun barrel to be telescopically adjusted, so that the phenomenon that a reducing agent is sprayed on an embedded pipe and cannot interact with high-temperature smoke, and consequently the purpose of denitration is influenced due to the fact that the spray gun is too short can be avoided, and the phenomenon that the spray gun is abraded rapidly due to the fact that the spray gun is too long can also be avoided. Besides, the spray gun can retreat from the interior of a boiler in time when not in use, so that the service life of the spray gun is greatly prolonged.
Description
Technical field
The present invention relates to a kind of spray gun, particularly relate to a kind of electric expansion spray gun.
Background technology
At present, owing to the operating temperature of SNCR denitrification spray gun is higher, in boiler, flue gas flow rate is very fast, and flue gas is carried secretly substantial amounts of dust, abrasion for spray gun is also very severe, and conventional spray gun cannot adjust due to length, causes that the end nozzle part of spray gun is quickly worn and burns. When wall thickness and the design of field working conditions or boiler have and come in and go out on a small quantity, owing in boiler, flue gas flow rate is very fast, flue-gas temperature is up to 850-1100 DEG C, and carries substantial amounts of dust in flue gas secretly. The words then nozzle that the built-in length of spray gun is long will soon be worn or burn, too short, cannot spray reductant in burner hearth. In boiler running process, spray gun is burned out, and loses out of stock function, and in boiler operatiopn, spray gun cannot be changed.
Summary of the invention
The technical problem to be solved is to provide a kind of electric expansion spray gun, the spray gun length putting in boiler can be carried out telescopic adjustment, both spray gun too short-range missile can have been avoided to cause reducing agent and to be sprayed onto on built-in pipe, cannot interact with high-temperature flue gas and affect out of stock purpose, it is avoided that again spray gun oversize and quickly weares and teares, significantly extend the bulk life time of spray gun.
The present invention solves that above-mentioned technical problem employed technical scheme comprise that a kind of electric expansion spray gun of offer, including nozzle and gun shot, described gun shot is hollow structure, the head of described gun shot is connected with nozzle, the afterbody of described gun shot is provided with water inlet and air inlet, wherein, described gun shot is provided with electric pushrod, one end of described electric pushrod is fixed on gun shot by intermediate plate, the other end is connected with drive motor, and described drive motor is connected with slide and is fixed on gun shot by bracket.
Above-mentioned electric expansion spray gun, wherein, described electric pushrod is that helical screw is secondary, and described helical screw pair is connected with drive motor by reduction gearing.
Above-mentioned electric expansion spray gun, wherein, described gun shot is provided with protection sleeve pipe.
Above-mentioned electric expansion spray gun, wherein, described gun shot is formed by Flange joint by two hollow steel tubes.
The present invention contrasts prior art following beneficial effect: electric expansion spray gun provided by the invention, by installing electric pushrod, drive motor and slide on gun shot additional, gun shot is driven to carry out telescopic adjustment, spray gun too short-range missile it is sprayed onto on built-in pipe thus both can have been avoided to cause reducing agent, cannot interact with high-temperature flue gas and affect out of stock purpose, it is avoided that again spray gun oversize and quickly weares and teares, and exit in time in stove in the spray gun not used time, significantly extend the bulk life time of spray gun.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is electric expansion spray gun structure schematic diagram of the present invention.
Refer to Fig. 1, electric expansion spray gun provided by the invention includes nozzle 1 and gun shot 2, described gun shot 2 is hollow structure, the head of described gun shot 2 is connected with nozzle 1, and the afterbody of described gun shot 2 is provided with water inlet 10 and air inlet 11, wherein, described gun shot 2 is provided with electric pushrod 7, one end of described electric pushrod 7 is fixed on gun shot 2 by intermediate plate 9, and the other end is connected with drive motor 13, and described drive motor 13 is connected with slide 12 and passes through bracket 5 and is fixed on gun shot 2. In order to realize limit function, one end of described slide 12 also can be provided with limitation travel switch 6 of giving up the throne, and the other end is provided with carry limitation travel switch 8.
Electric expansion spray gun provided by the invention, wherein, described electric pushrod 7 is that helical screw is secondary, described helical screw pair is connected with drive motor 13 by reduction gearing, drive motor 13 is power source, through speed change, drives screw mandrel screw pair to produce rectilinear motion, owing in electric pushrod 7, pipe and nut are fixing, connect equipment belt with the joint being connected in interior pipe to start building to make, the rotating of drive motor 13 produce the motion stretched or contract. Described gun shot 2 can be provided with protection sleeve pipe 3. Described gun shot 2 can be formed by connecting by flange 4 by two or many hollow steel tubes.
Electric expansion spray gun provided by the invention, wherein, described electric pushrod 7 can complete linear reciprocating motion, can also complete to rotate and swing by means of other mechanism. Electric pushrod 7 has a characteristic that 1, detent torque is big, can starting under load. 2, overload protecting mechanism and range controlling mechanism it are provided with, it is simple to user realizes automatically controlling. 3, adopt totally-enclosed sealing, be adapted at rugged environment and use. 4, volume is little, lightweight, installation and debugging convenient. 4, there is program control, the collection control meeting system requirements and the ability controlled on the spot.
Electric expansion spray gun provided by the invention, wherein, described electric pushrod 7 can adopt enumerator to carry out Stroke Control, it is possible to controls push rod any one fixed journey system or total travel operated within range in maximum travel limit.
