Abstract

The utility model relates to a dry steam generator which is composed of a heating pot body, a water spray pipe frame, a pot cover and a quantity of auxiliary members. The rotary radiation-shaped water spray pipe frame is arranged in the heating pot body and the pot cover. Pressure water enters the water spray pipe frame from a water inlet joint on the top of the pot cover, and is sprayed to the heating surface of the pot body from the water spray hole of a water spray branch pipe. Consequently, the steam is generated. The utility model has the advantages of good evaporating efficiency, simple structure, small volume, and light weight.

Description

The dry type steam generator

The utility model relates to steam boiler equipment.

The steam boiler of general now horizontal, vertical or other form mostly adopts pot body or body dress water ebuillition of heated to evaporate and obtains steam, because pot body or body dress water, its evaporating surface is limited, the steam that produces of its heating surface will break through thicker reservoir bed and just evaporates in addition, so evaporation efficiency greatly reduces.

The purpose of this utility model is that the not dry type steam generator of water storage of a kind of pot of body will be provided, and it can quicken the evaporation of steam, improves evaporation efficiency.

The utility model is made up of accessories such as heating kettle body, water spray pipe support, pot cover three main bodys and combustion chamber, tank, high-pressure pump, motor.The heating kettle body is a funnel type round metal pot body, and there is an axle sleeve that supports water spray pipe support swivel bearing at center, the end in its, and a plurality of limbers are arranged around the axle sleeve, is the delivery port joint of the surplus water of evaporation below the axle sleeve, and this joint connects the pipeline that leads to tank.The water spray pipe support is the radial metal pipe frame of " ten " font or " rice " font, its upright center water inlet pipe is communicated with all around radial water spray arm, in the water supply connector at suit pot cover center, water inlet pipe upper end, center, the lower end then is sleeved in the axle sleeve at center, the end in pot body.Also be connected with reinforcement between radial water spray arm and the center water inlet pipe.The spray-type air washer section of water spray arm is answered parallel heating kettle dignity and is drilled with equally distributed hole for water spraying in the side of corresponding pot body.Pot cover is the metal round cover that is complementary with pot shape, size, and its circumference edge of table has screw and by screw rod it and pot body is connected as a single entity.Pot cover Wai Ding center has one to turn to water supply connector, and muzzle is being adorned the water inlet pipe upper end, center of the pipe support of spraying water within the joint, and mouth links to each other with the press water feed pipe outside the joint.Be processed with an external line shaft socket and be furnished with an external line shaft at the upside over against this joint internal orifice center line, in this bayonet socket by the water inlet pipe upper end, center of the water spray pipe support of socket insertion joint internal orifice institute suit, sealing and gland are equipped with in the socket outside.In addition, Pressure gauge and steam (vapor) outlet joint also are equipped with in the outer top of pot cover.If this utility model electrical heating only needs electric hot plate is attached on pot body and get final product: if with the heating of coal oil gas, then need be in construction combustion chamber, pot body bottom.

It is the steam efficiency height that the utility model comes major advantage compared with traditional dress water boiling steam boiler, structure tube list besides, and volume is little, and is in light weight.

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:

Fig. 1 is the dry type steam generator structural representation of coal oil gas burning heating.

Fig. 2 is electrically heated dry type steam generator structural representation.

Among the figure 1, water spray pipe support lower bearing 2, heating kettle body 3, water spray arm 4, water spray pipe support 5, pot cover 6, steam (vapor) outlet joint 7, water inlet joint 8, packing ring gland 9, external line shaft 10, air gauge 11, center water inlet pipe 12, bolt 13, hole for water spraying 14, electric boiling plate 15, water spray pipe support reinforcement 16, combustion chamber 17, high-pressure hydraulic pump 18, tank

As depicted in figs. 1 and 2, its main element of the utility model has heating kettle body 2, water spray pipe support 4 and pot cover 5, and its auxiliary equipment has tank 18, high-pressure hydraulic pump 17 and driving motor etc., also need build combustion chamber 16 with what the burning of coal oil gas was heated.In the main element, heating kettle body 2 is formed by metal stamping formed or weldering system resistant to elevated temperatures and that heat conductivity is good, and axle sleeve 1 at center, the end is answered fine finishining in it, the limbers electric drill processing around this axle sleeve.The size of " ten " font or the radial water spray pipe support 4 of " rice " font should be complementary with pot body size, is advisable for 10 to 30 centimetres with spacing pot body wall.The radical of radial water spray arm 3 should increase with the increase of pot body 2 diameters.Water spray arm 3 is connected on the center water inlet pipe 11 both intracavity inter-connections by reinforcement 15.Water inlet pipe 11 lower ends in center are sleeved in the axle sleeve 1 at center, the end in pot body, and the upper end then is sleeved in the internal orifice of water supply connector 7 at pot cover Wai Ding center.Water spray arm 3 is processed with equally distributed water spray aperture 13 over against the side of pot body.Pipe support 4 usefulness steel pipes and the reinforcing bar weldering system of spraying water forms, and its center water inlet pipe 11 upper and lower sides answer fine finishining to make it to be complementary with the axle sleeve at center, the interior end of pot body and the water supply connector internal orifice at pot cover Wai Ding center.The hole for water spraying of its water spray arm is processed by electric drill or bench drill, and is rare under the Ying Shangmi.Pot cover 5 is by making type with 2 identical materials punch formings of pot body or weldering, be welded on the pot cover behind the socket of should first fine finishining good inside and outside mouthful of water supply connector 7 at its Wai Ding center and external line shaft 9,6 of its air gauge 10 and steam (vapor) outlet joints are welded on both sides, pot cover top again.During assembling, water inlet pipe 11 lower ends, the pipe support center cover of will spraying water is earlier put in the axle sleeve 1 at center, the end in the pot body 2, again pot cover 5 is covered on the pot body 2, the center water inlet pipe 11 upper ends cover of pipe support 4 of noting simultaneously spray water is put in the internal orifice of water inlet joint 7 at the center of pushing up on the pot cover, follow the connecting bolt 12 of first-class pot body and pot cover edge of table, insert external line shaft 9 and first-class seal washer and gland 8 then, then main element installs.In auxiliary equipment, driving motor is selected different power models, the external line shaft 9 of its transmission after slowing down according to the size of water spray pipe support 4.Tank 18 should be built the main element below in, in the pipeline that the 2 times end connectors in it and pot body are connected the drain valve that can allow the surplus water of evaporation flow through and not allow steam pass through should be housed.Tank should be sufficiently big, is used for evaporation with the water that guarantees long period supply water spray pipe support.High-pressure hydraulic pump 17 is used for extracting the water of tank 18 for water spray pipe support water spray; Enough big as on-the-spot running water pipe hydraulic pressure, the pipe support of then spraying water water inlet is running water pipe and do not need high-pressure hydraulic pump 17 to draw water directly.When with fuel combustions such as coal oil gas heating, then should build different combustion chambers 16 according to different fuel, the size of combustion chamber and shape should consider to make full use of the heating surface of pot body 2.
