Abstract
The utility model discloses a blowback spray head which comprises a nozzle A, a nozzle B, sleeve holes, holes and a U-shaped ring, wherein the nozzle A and the nozzle B are of a whole piece of a coaxial shaft hollow cavity; the two symmetrical holes are formed in the nozzle A; the two symmetrical sleeve holes are formed in the outer wall of the nozzle B; an arc groove is formed in the port of the nozzle B; and external threads are respectively formed in two ends of the U-shaped ring. The spray head is fixed in the following two-step mounting manners: firstly, the U-shaped ring is buckled at an air inlet part in an air filter drum, and the two ends of the U-shaped ring are respectively mounted into the sleeve holes in a sleeving manner, and are fastened by bolts to prevent the U-shaped ring from falling; and secondly, the plane end face of the nozzle B is connected with the air inlet part in the air filter drum in a welding manner. Gas is sprayed out from the nozzle A and the two holes in the nozzle A to clean the inner wall of the drum, and the gas is also sprayed out from the arc groove of the nozzle B to perform back flushing on the inner wall of the drum.
Description
Technical field:
The utility model relates to a kind of shower nozzle, relates in particular to a kind of blowback shower nozzle.
Background technology:
Shower nozzle is installed in the air cleaner mostly, air cleaner in use, shower nozzle helps to spread gas in the filter cylinder, also can remove filter cylinder inwall dust; Existing shower nozzle has the following disadvantages: (1) gas sprays from shower nozzle and can only wash the filter cylinder inwall, can't carry out backwash to the filter cylinder inwall; (2) installation method of shower nozzle generally is fixed on air inlet position in the air cleaner filter cylinder by screw, phenomenons such as screw becomes flexible or shower nozzle comes off can appear in long-term the use, because shower nozzle is installed in the air cleaner filter cylinder, fragile cylindrical shell when splitting away off, can directly influence the service life of filter and the quality quality of gas filtration, also increase the cost of investment of enterprise; The high frequency time of shower nozzle is installed and changed, also cause the waste of lot of manpower and material resources to enterprise.
The utility model content:
The utility model provides a kind of blowback shower nozzle that can prolong the service life of filter and improve filter effect at the deficiencies in the prior art.
For realizing the above object, the technical solution adopted in the utility model is:
A kind of blowback shower nozzle is made up of nozzle A, nozzle B, trepanning, hole, U-shaped ring; Nozzle A, nozzle B are the single piece of concentric shafts hollow cavity, have the hole of two symmetries on the nozzle A, and the nozzle B outer wall is provided with the trepanning of two symmetries, and the nozzle B port is provided with arc groove; U-shaped ring two ends are respectively equipped with external screw thread, and two ends are set in the trepanning, and are fastening in addition by bolt, prevent that U-shaped ring from coming off.
The long-pending radial section greater than nozzle A of the radial section of described nozzle B is long-pending.
The length of described nozzle A is greater than the length of nozzle B.
The utility model fix shower nozzle by following two step mounting means, and the first step is by U-shaped latch closure air inlet position in the air cleaner filter cylinder, and U-shaped ring two ends are set in the trepanning that to pass through bolt in addition fastening, prevent that U-shaped ring from coming off; Second step was that the planar end surface of nozzle B is connected by welding manner with the interior air inlet position of air cleaner filter cylinder; Solve the problem that existing product in use exists, prevented that shower nozzle from use coming off, can reduce the installation of shower nozzle and change number of times, saved the man power and material, prolonged the service life of air cleaner, reduced company investment cost; Spray two holes of gas on nozzle A, nozzle A simultaneously the filter cylinder inwall is cleaned, gas also sprays from the arc groove of nozzle B the filter cylinder inwall is carried out backwash.

Fig. 1 is structural representation of the present utility model;
Fig. 2 does not install the structural representation of U-shaped ring for the utility model;
Fig. 3 is the front view of Fig. 2;
Fig. 4 is the left view of Fig. 2;
Fig. 5 is the vertical view of Fig. 2.
The specific embodiment:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of blowback shower nozzle is made up of nozzle A1, nozzle B 2, trepanning 3, hole 4, U-shaped ring 5; Nozzle A1, nozzle B 2 are the single piece of concentric shafts hollow cavity, have the hole 4 of two symmetries on the nozzle A1, and nozzle B 2 outer walls are provided with the trepanning 3 of two symmetries, and nozzle B 2 ports are provided with arc groove 6; U-shaped ring 5 two ends are respectively equipped with external screw thread, and two ends are set in the trepanning 3, and are fastening in addition by bolt, prevent that U-shaped ring 5 from coming off; The long-pending radial section greater than nozzle A1 of the radial section of described nozzle B 2 is long-pending; The length of described nozzle A1 is greater than the length of nozzle B 2.
By following two step mounting means shower nozzle is fixed during enforcement, the first step is to be buckled in air inlet position in the air cleaner filter cylinder by U-shaped ring 5, and the two ends of U-shaped ring 5 are set in the trepanning 3, and are in addition fastening by bolt, prevent that U-shaped ring 5 from coming off; Second step was: the planar end surface 7 of nozzle B 2 is connected by welding manner with the interior air inlet position of air cleaner filter cylinder; Spray two holes 4 of gas on nozzle A1, nozzle A1 the filter cylinder inwall is cleaned, gas also sprays from the arc groove 6 of nozzle B the filter cylinder inwall is carried out backwash simultaneously.
The utlity model has advantage such as evenly simple in structure, easy for installation, jet, have great promotional value.
