Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The utility model discloses an air inlet mechanism with prevent wind husky function, as shown in figure 1, it is including the shell 1 that is the cuboid shape. An installation groove for installing the air inlet mechanism is reserved at the bottom of the shell of the oil field well head heat exchanger, and the shape of the installation groove is matched with that of the shell 1; or directly form the shell 1 structure on the casing of the oil field well head heat exchanger, and then install each wind and sand prevention mechanism inside the shell 1.

Still as shown in fig. 1, the top at shell 1 is linked firmly and is connected shell 2, and the length of connecting shell 2, width all are less than shell 1, stretch into the air inlet and the fixed mounting of combustion chamber here by connecting shell 2 to, make the air after this novel mechanism of admitting air handles, directly enter into the combustion chamber from connecting shell 2.

In order to facilitate the air in the outer shell 1 to enter the connecting shell 1, as shown in fig. 1, a plurality of air homogenizing holes 3 are formed on the top wall of the outer shell 1, and the air required for combustion is uniformly fed into the air homogenizing holes 3.

For the air inlet mechanism with the wind and sand prevention function disclosed by the utility model, as shown in fig. 2, the air inlet mechanism further comprises a first-stage wind and sand prevention mechanism 10 and a second-stage wind and sand prevention mechanism 5, sand and stones in the air are effectively isolated by the first-stage wind and sand prevention mechanism 10 and the second-stage wind and sand prevention mechanism 5, and the wind and sand are prevented from blocking an air inlet;

first, as shown in fig. 2, the inside of the housing 1 is hollow, and the bottom end of the housing 1 is an open opening, so that the second-stage wind and sand prevention mechanism 5 is detachably mounted at the open opening at the bottom of the housing 1, as shown in fig. 3, the second-stage wind and sand prevention mechanism 5 includes a wind and sand prevention bucket 50, the wind and sand prevention bucket 50 is a main structure of the second-stage wind and sand prevention mechanism 5 having a wind and sand prevention function, the wind and sand prevention bucket 50 has a side wall arranged obliquely, when air mixed with wind and sand enters the air intake mechanism, the wind and sand prevention bucket 50 can block the entrance of sand and stone by inclining the side wall, and the air as a fluid can continue to flow upward along the side wall of the wind and sand prevention bucket 50, and then enters the housing 1.

As also shown in fig. 2, the primary wind and sand prevention mechanism 10 is located in the wind prevention bucket 5 of the secondary wind and sand prevention mechanism 5, the primary wind and sand prevention mechanism 10 performs primary treatment, and the secondary wind and sand prevention mechanism performs secondary treatment; as shown in fig. 4, the primary wind and sand prevention mechanism 10 includes a plurality of sets of wind prevention blades 101 inclined in the same direction, and the wind prevention blades 101 are fixedly connected with the wind scoops 5 through fixing shafts 102. Similarly, the inclined wind-proof blades can block the entrance of sand and stone, and gaps are arranged among the wind-proof blades 101, and air enters the secondary wind-proof sand mechanism 5 through the gaps and then is subjected to secondary wind-proof sand treatment by the wind-proof bucket 50.

After the second-stage wind and sand prevention mechanism is used for processing, a very small amount of sand and stones may still enter the shell 1, and as the shell 1 has a certain height, a small amount of sand and stones fall under the action of gravity, part of sand and stones directly fall from the opening at the top end of the wind prevention hopper 50, and part of sand and stones fall into the shell 1, therefore, in order to facilitate the collection and discharge of the sand and stones left in the shell 1, as shown in fig. 2 and 3, the bottom end of the wind prevention hopper 50 is fixedly connected with a sand bag plate 51 which is horizontally arranged and is enclosed around the wind prevention hopper 50, the peripheral edges of the sand bag plate 51 are also fixedly provided with vertical upward side connecting plates 53, and the side connecting plates 53 are enclosed around the bottom end of the shell 1; thus, the falling sand is collected in the casing 1 by the sand pocket plate 51.

Moreover, in order to facilitate the discharge of the sand collected by the sand-containing plate 51 and the overhaul of the air inlet machine, the secondary sand-preventing mechanism is detachably mounted at the open type opening at the bottom of the shell 1, as shown in fig. 2 and 3, a slot 52 is formed in the sand-containing plate 51, the bottom end of the shell 1 is inserted into the slot 52, and then the side connecting plates 53 are arranged around the shell 1; meanwhile, in order to improve the sealing performance between the side connecting plate 53 and the housing 1, as shown in fig. 2, a sealing ring 7 is arranged between the side connecting plate 53 and the housing 1 in a sealing manner; furthermore, a protective cover 4 is fixedly arranged on the shell 1, the protective cover 4 covers the periphery of the side connecting plate 53, and the protective cover 4 further improves the protection of the connecting gap between the side connecting plate 53 and the shell 1. Finally, the protective cover 4, the side connecting plate 53, the sealing ring 7 and the shell 1 are detachably connected through fastening bolts, and the installation of the secondary wind and sand prevention mechanism is completed.

The air after the husky mechanism of wind-proof through one-level, second grade is handled, can not mix with the sand blown by the wind basically, however, for further improving the air quality who gets into the combustion chamber, impurity such as the dust that mix with in the reduction air still is provided with filter screen 8 in shell 1, and filter screen 8 is located shell 1's roof below, also adopts the method installation of dismantling the connection, specifically has: as shown in fig. 2, L-shaped fixing frames 9 are symmetrically and fixedly arranged on the inner wall of the housing 1, and the filter screen 8 is detachably mounted on the L-shaped fixing frames 9 through fastening bolts. For the filter screen, adopt the wire mesh filter screen, the wire mesh filter screen can recycle, long service life to the wire mesh filter layer is a porous functional material, has even aperture distribution and excellent fluid permeability, can make the tiny particle solid impurity in the gas get rid of under the prerequisite that does not influence the gas flow.

In addition, because this air inlet mechanism is located the chassis bottom of oil field well head heat exchanger, in order to prevent that mouse worm etc. from entering into air inlet mechanism, as shown in fig. 2, shell 1 wind-proof fill 50 stretches into the inside of shell 1, and the top of wind-proof fill 50 has linked firmly extension seat 54, and the metal separates net 6 is installed to the opening part of extension seat 54, and metal separates the net 6 under the prerequisite that does not influence the air flow, and the entering of separation mouse worm etc..

The air inlet mechanism with the wind and sand prevention function is provided with the primary wind and sand prevention mechanism, the secondary wind and sand prevention mechanism and the filter screen, and sand and stone mixed with air entering a combustion chamber and small particle impurities are effectively separated, so that the probability of air inlet blockage is reduced, and the efficient and normal work of the oil field well heat exchanger is ensured; meanwhile, the primary wind and sand prevention mechanism is fixed in the secondary wind and sand prevention mechanism, and the secondary wind and sand prevention mechanism is detachably arranged, so that the air inlet mechanism is convenient to overhaul; and, even if there is very little sand blown by the wind to enter into the shell, because shell 1 has a take the altitude, also can make the gravel and sand drop under the action of self gravity, and the gravel and sand that part drops in shell 1 is collected by the sand pocket board, when taking out the second grade and prevent wind husky mechanism, can be arranged the gravel and sand that collects outward.
