Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
the embodiment provides a sewage treatment is with preventing blockking up aeration head, refer to fig. 1, and it includes main part 1, has two cavitys of arranging from top to bottom in the main part 1, and the slip core is installed in two cavitys and can reciprocate along the axial of two cavitys. The bottom of the first cavity positioned at the upper part is provided with a through hole communicated with the second cavity, and the edge of the port at the upper end of the first cavity extends towards the center of the port to form a circular spigot. The second cavity comprises a cylindrical cavity in communication with the bore. The slip core includes sealed gluey lid 2, jet-propelled post 3, sliding shaft from top to bottom in proper order, and sealed gluey lid 2 is the circular platelike structure of fixing on 3 terminal surfaces of jet-propelled post, and sealed gluey lid 2 edge is vertical bending down and is formed annular hat brim portion 201, jet-propelled post 3 is the step-like structure that two sections cylinders of variation in size constitute, and the cylinder section that is located the upper portion is less than the cylinder section of lower part so that the marginal portion of the cylinder section of lower part forms the annular step face still seal ring 4 has been inlayed on the step face, and half of seal ring 4 exposes the step face, jet-propelled post 3 moves up and when making the cylinder section of upper portion stretch out first cavity seal ring 4 with the interior terminal surface extrusion contact of tang and realize sealedly. The sliding shaft is coaxially connected to the bottom end face of the step, penetrates out of the through hole downwards, extends into the cylindrical cavity of the second cavity, then extends out of the cylindrical cavity and is connected with the gas pipeline, the sliding shaft is further provided with an annular shaft shoulder 6, and the shaft shoulder 6 can axially slide in the cylindrical cavity of the second cavity. The sliding core is also internally provided with an aeration channel, the aeration channel comprises an aeration main channel 301 and an aeration branch channel 302 which are communicated with each other, the aeration main channel 301 is coaxially arranged in the sliding shaft and the air injection column 3 and does not axially upwards penetrate through the air injection column 3, the aeration main channel 301 is connected with the air transmission pipeline through the sliding shaft to realize the communication with an air source, the aeration branch channels 302 are arranged in a circular array along the radial direction of the upper cylindrical section of the air injection column 3 so as to uniformly aerate towards the periphery, and in order to improve the aeration rate, the aeration branch channels 302 are arranged in a plurality of circles along the axial direction of the upper cylindrical section. In particular, the aperture of the aeration branch flow channel 302 of the present embodiment is smaller than the thickness of the seam allowance, so that when the air injection column 3 slides out of the port of the first cavity, the seam allowance can be primarily sealed with the air injection column 3 all the time, and dregs are prevented from being jammed into the first cavity when the air injection column 3 slides out, and the thickness of the seam allowance is preferably larger than twice the diameter of the aeration branch flow channel 302. On the basis of the structure, this embodiment still includes reset spring 5, and reset spring 5 overlaps coaxially and is established on the sliding shaft between the interior roof of shaft shoulder 6 and cylinder cavity, and with the sliding core jack up down to under non-aeration state brim of a hat portion 201 card of sealing rubber cover 2 is gone into in the annular seal slot of seting up around the tang terminal surface to realize the shutoff and seal. The aeration head of this embodiment utilizes reset spring 5 to control the leakproofness of whole aeration head when out of operation, prevents that debris from blockking up the aeration head, and during the aeration, the air current strikes jet-propelled post 3, make jet-propelled post 3 expose the port of first cavity, make each aeration branch runner 302 in jet-propelled post 3 begin to supply air around, and at this moment, sealing washer 4 on the step face of jet-propelled post 3 and the interior terminal surface extrusion contact of tang of first cavity have realized sealedly, thereby make in operation, debris can not enter into in the aeration head yet, thereby realized that the aeration head all realizes sealedly when the aeration with in stewing, avoid blockking up.
As a specific implementation detail, referring to fig. 2, an angle between the aeration branch flow channel 302 and the aeration main channel 301 is such that the airflow beam ejected from the aeration branch flow channel 302 does not intersect with the step surface, that is, the airflow ejected from the aeration branch flow channel 302 obliquely and directly impinges on the inner sidewall of the first cavity in a downward divergent direction, and due to the principle of acting force and reaction force, the entire air jet column 3 is pushed to slide towards the outside of the first cavity.
In order to further ensure the sealing performance and prevent the dregs from entering the first cavity when the air injection column 3 slides out, an O-shaped ring 7 is embedded on the inner side wall of the seam allowance, so that the air injection column 3 can slide and hermetically pass through the O-shaped ring 7 when sliding.
In order to ensure that the air injection column 3 completely extends in place to ensure that the sealing ring 4 can be in contact and seal with the inner end face of the spigot, a plurality of air exhaust holes 101 are specially formed in the spigot, the air exhaust holes 101 are parallel to the axial direction of the spigot and are opposite to the step face, so that air between the inner end face of the spigot and the step face is compressed out, the O-shaped ring 7 is ensured to be in more sufficient contact with the inner end face of the spigot, and meanwhile, the sealing rubber cover 2 is made to be large and small to cover all the air exhaust holes 101, so that the covering and sealing of the aeration head are realized.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
