Abstract

The invention discloses an internal-throttling rotary isopiestic granulating nozzle which comprises a nozzle body, a big sealing head, a small sealing head; the big sealing head is connected with the nozzle body; the nozzle body is connected with the small sealing head to form an inner cavity; the invention also comprises a central tube which is connected with the big sealing head; one end of thecentral tube is disposed in the inner cavity; the part of the central tube located inside the inner cavity is provided with several clapboards; the clapboards are sealed with the inner wall of the nozzle body; the clapboards partition the inner cavity into several small cavities which are independently sealed; a throttling hole is disposed on each section of the central tube in each independently-sealed small cavity; the clapboards are perpendicular to the central line of the central tube; the throttling holes are uniformly arranged in a circumferential direction of the central tube; the central tube is connected with the clapboards in a welding manner; the nozzle body is connected with the big sealing head by a flange; the small sealing head is connected with the nozzle body by welding; the invention can increase the product quality of urea, and reduce atmosphere and environmental pollution.

Description

Internal-throttling rotary isopiestic granulating nozzle
Technical field
The present invention relates to a kind of tower urea granulation plant, relate in particular to a kind of internal-throttling rotary isopiestic granulating nozzle.
Background technology
In the present employed urea granulation sprayer, because shower nozzle has certain height (general about 20~40cm), according to theorem and formula P=ρ gh as can be known, liquid internal pressure increases along with the increase of the degree of depth of liquid, wherein P is liquid internal pressure, ρ is fluid density, and g is local gravitational acceleration, and h is the degree of depth of liquid.Urine increases gradually at the inner edge of shower nozzle directional pressure from top to bottom like this, and staggered, the problems such as urea granules is hollow, Dust Capacity increase of space of lines will occur to spray its result, therefore exist following defective:
1. affect Urea Quality;
2. atmosphere is polluted.
Summary of the invention
The present invention is exactly above-mentioned because of the problem that urine is poor to the inhomogeneous Urea Quality that causes of shower nozzle inner wall pressure, atmosphere pollution is heavy in order to solve; A kind of internal-throttling rotary isopiestic granulating nozzle is provided; Urea Quality be can improve, atmosphere and environmental pollution reduced.
To achieve these goals, the present invention adopts following technical scheme:
Internal-throttling rotary isopiestic granulating nozzle, comprise sprayer body, large end socket, little end socket, described large end socket is connected with sprayer body, described sprayer body and little end socket are connected to form inner chamber, also comprise central tube, described central tube is connected with large end socket, described central tube one end is located among the inner chamber, and the part that described central tube is positioned at inner chamber is provided with some dividing plates, described dividing plate and sprayer body inner wall sealing, described dividing plate is divided into some independent little cavitys that seal with inner chamber, and every section central tube in described each little cavity that independently seals is provided with throttle orifice.
Described dividing plate is vertical with the center line of central tube.
Described throttle orifice evenly disposes at the central tube circumferencial direction.
Described central tube is that welding manner is connected with dividing plate.
Described sprayer body is connected by flange with large end socket.
Described little end socket and sprayer body are welding.
Beneficial effect of the present invention: because internal-throttling rotary isopiestic granulating nozzle of the present invention is provided with central tube, described central tube is connected with large end socket, described central tube one end is located among the inner chamber, the part that described central tube is positioned at inner chamber is provided with some dividing plates, described dividing plate and sprayer body inner wall sealing, described dividing plate is divided into some independent little cavitys that seal with inner chamber, and every section central tube in described each little cavity that independently seals is provided with throttle orifice.Some dividing plates have been divided into relatively independent chamber with shower nozzle inside, throttle orifice on the central tube makes urine enter into each chamber, urine is in the process of these throttle orifices of flowing through, and throttle orifice is equal to the effect that urine produces reducing pressure by regulating flow so that enter the pressure of each chamber after the throttling.Simultaneously sprayer body is made as flange with large end socket and removably connects, and the flange of untiing large end socket and sprayer body just can separate sprayer body and remainder.Therefore have technique effect:
1, realize that urine distributes to the shower nozzle inwall is isobaric, it is staggered to reduce the sprinkling space of lines, improves urea product dynamics qualification rate, reduces dust.
2, open and inspect conveniently, be convenient to clean and Inspection and maintenance.
Description of drawings
Fig. 1 is the shower nozzle schematic diagram of internal-throttling rotary isopiestic granulating nozzle of the present invention.
1-flange among the figure, 2-central tube, the large end socket of 3-, 4-sprayer body, the little end socket of 5-, 6-dividing plate, 7-throttle orifice.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment.
In conjunction with Fig. 1, internal-throttling rotary isopiestic granulating nozzle, sprayer body 4, large end socket 3, little end socket 5, described large end socket 3 is connected with sprayer body 4, described sprayer body 4 is connected to form among the inner chamber with little end socket 5, it is characterized in that, also comprises central tube 2, described central tube 2 is connected with large end socket 3, described central tube 2 one ends are located at inner chamber, and the part that described central tube 2 is positioned at inner chamber is provided with some dividing plates 6, described dividing plate 6 and sprayer body 4 inner wall sealings, described dividing plate 6 is divided into some independent little cavitys that seal with inner chamber, and the every section central tube 2 in described each little cavity that independently seals is provided with throttle orifice 7; Described dividing plate 6 is vertical with the center line of central tube 2; Described throttle orifice 7 evenly disposes at central tube 2 circumferencial directions; Described central tube 2 is connected for welding manner with dividing plate 6; Described sprayer body 4 and large end socket 3 are connected by flange; Described little end socket 5 is welding with sprayer body 4.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
