Description

Technical Field

[0001] The invention relates to a nozzle, in particular to a self-cleaning explosion nozzle. Background Art

[0002] Aeration nozzles are commonly used in sewage treatment equipment and waste gas treatment equipment. The aeration nozzles are switched at regular intervals. The switching interval is related to the maintenance cycle of the treatment equipment. The switched aeration nozzles will not be removed for cleaning, but will wait for the next switch;

[0003] Because the aeration nozzle is in a silent state at this time, substances in the sewage or exhaust gas will fall on the aeration nozzle, such as flocs, particulate matter or algae. When these substances accumulate to a certain extent, they will block the air outlet of the aeration nozzle, thereby affecting the treatment effect of the equipment. Replacing the aeration nozzle requires emptying the sewage or waste in the equipment, which has a long replacement cycle, a large workload, and will also reduce production capacity.

[0004] The existing solutions are:

[0005] When the existing explosion nozzle is blocked, the blocked area is forcibly flushed by high-pressure flushing. The consequence of this is that a large amount of gas impacts the equipment, causing the equipment to fluctuate in a certain period of time, and in severe cases, the equipment will stop. Therefore, the person performing this operation must be an experienced master;

[0006] Or use frequent switching to prevent the existing explosion nozzle from being blocked due to long-term static state. This method will also cause the two machines to run in parallel during switching, causing equipment fluctuations, and in severe cases, causing the equipment to stop. Therefore, the person performing this operation must also be an experienced master. Summary of the invention

[0007] The technical problem to be solved by the present invention is: to provide a self-cleaning explosion nozzle in order to overcome the deficiencies in the prior art.

[0008] The technical solution adopted by the present invention is: a self-cleaning explosion nozzle, comprising an outer body and an inner body, wherein the outer body has a chamber inside, a plurality of air-permeable windows are evenly arranged around the chamber wall, the top end of the outer body has an opening, the bottom end of the outer body has a connecting joint, the inner body is arranged in the chamber in the interval area between the opening and the connecting joint, the inner body is arranged vertically with the bottom of the chamber, and the inner body is connected with the connecting joint;

[0009] The inner body includes an outer shell and an air column. The upper part of the outer shell is provided with an air outlet chamber. The outside of the air outlet chamber is provided with an air outlet, and the air outlet faces the vibrator. The vibrator is installed on the outside of the outer shell. A pressure regulating structure is provided in the air outlet chamber. The pressure regulating structure is installed on the through hole at the bottom of the air outlet chamber. An air column is provided at the bottom of the through hole. The air column is a circular tube with a hollow interior. The opening at the top of the circular tube is connected to the through hole. The opening at the bottom of the circular tube is provided in a connecting joint. A plurality of through air outlet holes are provided on the tube walls of the circular tube and the outer shell, and the air outlet holes are provided near the bottom of the chamber.

[0010] Furthermore, a plurality of air vents are evenly arranged around the chamber wall, and the air vents include an upper air vent and a lower air vent opened up and down. An air outlet duct is arranged at the rear end of the upper air vent, and a height of the air outlet duct close to the upper air vent is greater than a height of the air outlet duct close to the inside of the chamber.

[0011] Furthermore, a vibrator is arranged at the rear end of the outlet air passage, and the air outlet is located below the lower air vent.

[0012] Furthermore, the vibrators are arranged at one-to-one intervals at the rear end of the ventilation window.

[0013] Furthermore, the vibrator is a spirally wound metal ring, there is a distance between the metal ring and the shell, and there is also a distance between the metal ring and the chamber.

[0014] Furthermore, the air outlet is arranged obliquely, and the height of the air outlet on a side close to the air outlet chamber is greater than the height of the air outlet on a side away from the air outlet chamber.

[0015] Furthermore, the voltage regulating structure is a metal ball, the diameter of the metal ball is larger than the diameter of the through hole, and the diameter of the through hole is larger than the diameter of the top opening of the circular tube.

[0016] Furthermore, a buffer chamber is provided between the shell and the air column, a plurality of first air outlet holes are provided on the tube wall of the circular tube, a plurality of second air outlet holes are provided on the tube wall of the shell, and the first air outlet holes and the second air outlet holes are staggered with each other.

[0017] Furthermore, a combination piece is arranged in the opening.

[0018] Furthermore, the assembly is threadedly connected to the opening, and the assembly is a blind plug, an air outlet pipe or a mesh plug.

[0019] Compared with the prior art, the present invention has the following advantages: the self-cleaning explosion nozzle of the present invention has the self-cleaning function, can greatly extend the replacement cycle, has a simple structure and is easy to maintain in the later stage, and is not easy to be blocked. Specifically:

[0020] It has a self-cleaning function. The air outlet faces the vibrator. Under high pressure, the pressure will lift up the pressure regulating structure (metal ball), and the air will blow from the air outlet to the vibrator. The vibrator will vibrate, stirring the sewage or waste in the equipment, making the originally compacted materials loose. The gas blown out of the air outlet and the air hole will blow up and stir the loose materials.

[0021] It has high and low pressure adjustment. Under low pressure, the air pressure cannot lift up the pressure regulating structure (metal ball). The airflow blows out from the air outlet to blow up and stir the loose materials, thus reducing energy consumption while ensuring the explosion effect.

[0022] The structure is simple and easy to maintain in the later stage. The top of the outer body has an opening, which is connected to the chamber. The inner body can be quickly disassembled and assembled through the opening.

[0023] And it is not easy to be blocked, which is reflected in that the air vent is opened on the wall of the chamber, and the material is affected by gravity, and it takes a long time to block the air vent from the side; secondly, an outlet air duct is arranged at the rear end of the upper air vent, and the outlet air duct is inclined. When there is no flow or pressure difference between the chamber and the outside world, it is not easy for the material to enter the chamber, thereby reducing the blockage; thirdly, the air outlet is also inclined from top to bottom, so that it is not easy for the material to enter from the air outlet and block the air column; finally, a plurality of first air outlet holes are opened on the tube wall of the circular tube, and a plurality of second air outlet holes are opened on the tube wall of the outer shell, the first air outlet holes and the second air outlet holes are staggered with each other, and there is a buffer chamber between the first air outlet hole and the second air outlet hole, when there is no flow or pressure difference between the air column and the outside world, it is not easy for the material to enter the air column, and even if a small amount of material passes through the second air outlet hole, it will be intercepted in the buffer chamber.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Figures 1 to 8 A self-cleaning explosion nozzle is shown, comprising an outer body 10 and an inner body 20, wherein the outer body 10 has a chamber 11 inside, and a plurality of air windows are evenly arranged around the wall of the chamber 11, the top end of the outer body 10 has an opening 12, and the bottom end of the outer body 10 has a connecting joint 13, the inner body 20 is arranged in the chamber 11 in the area between the opening 12 and the connecting joint 13, the inner body 20 is vertically arranged with the bottom of the chamber 11, and the inner body 20 is connected with the connecting joint 13; a plurality of air windows are evenly arranged around the wall of the chamber 11, and there is a distance between the air windows and the inner body 20.

[0035] The inner body 20 includes an outer shell 21 and an air column 22. The upper part of the outer shell 21 has an air outlet chamber 23. The outside of the air outlet chamber 23 is provided with an air outlet 24. The air outlet 24 faces the vibrator 25. The vibrator 25 is installed on the outside of the outer shell 21. A pressure regulating structure 26 is provided in the air outlet chamber 23. The pressure regulating structure 26 is installed on the through hole 27 at the bottom of the air outlet chamber 23. The air column 22 is provided at the bottom of the through hole 27. The air column 22 is a circular tube with a hollow interior. The opening 12 at the top of the circular tube is connected to the through hole 27. The opening 12 at the bottom of the circular tube is provided in the connecting joint 13. A plurality of through air outlet holes are provided on the tube walls of the circular tube and the outer shell 21. The air outlet holes are provided near the bottom of the chamber 11.

[0036] Specifically, the vibrator 25 is a spirally wound metal ring, there is a distance between the metal ring and the housing 21, there is also a distance between the metal ring and the chamber 11, the outer portion of the housing 21 has a mounting position, the metal ring is fixed by screws and threads of the mounting position, welding and other methods are also possible;

[0037] The pressure regulating structure 26 is a metal ball. In order for the metal ball to have a better sealing effect, the diameter of the metal ball is larger than the diameter of the through hole 27 , and the diameter of the through hole 27 is larger than the diameter of the top opening 12 of the circular tube.

[0038] The present invention solves the problems of conventional explosion nozzles with general explosion effect and easy blockage. The present invention adopts the following design:

[0039] First, the application can achieve the purpose of sufficient explosion when used online. At the same time, when in a static state, the substances in the sewage or exhaust gas block the ventilation window. The ventilation window also includes an upper ventilation window 29 and a lower ventilation window 30 opened up and down. An outlet air channel 34 is arranged at the rear end of the upper ventilation window 29. The height of the outlet air channel 34 close to the side of the upper ventilation window 29 is greater than the height of the outlet air channel 34 close to the side of the chamber 11. When used online, the gas in the chamber 11 diffuses upward under the guidance of the outlet air channel 34, thereby increasing the explosion area of ​​the equipment. When in a static state, since the ventilation window is opened on the side of the outer body 10, it is difficult for substances to directly block the ventilation window; the lower ventilation window 30 horizontally sweeps the sewage or exhaust gas in the equipment to prevent the substances from being deposited at the bottom, thereby improving the explosion effect;

[0040] Secondly, the air outlet 24 is inclined, and the height of the air outlet 24 close to the air outlet chamber 23 is greater than the height of the air outlet 24 away from the air outlet chamber 23, that is, the state of high in the middle and low on both sides shown in the figure. With this design, when the present application is in a static state, the substances in the sewage or exhaust gas will not enter the air column 22 through the air outlet 24 and block the air column 22;

[0041] Finally, a buffer chamber 28 is provided between the shell 21 and the air column 22. A plurality of first air outlets 31 are provided on the tube wall of the circular tube, and a plurality of second air outlets 32 are provided on the tube wall of the shell 21. The first air outlets 31 and the second air outlets 32 are arranged staggered with each other. With such a design, when the present application is in a static state, only a small amount of substances in the sewage or waste gas can enter the buffer chamber 28 through the second air outlets 32, ensuring that the first air outlets 31 will not be blocked.

[0042] As long as the air outlet 24 is not blocked, the airflow ejected from the air outlet 24 generates vibration when passing through the vibrator 25, thereby achieving the unblocking work, and the fastened material can be loosened and stirred by the airflow.

[0043] In order to further improve the blocking effect of this application, this application adopts the following design:

[0044] First, when the material is in a static state, it is easy for the material to accumulate in the outlet flow channel 34. For this reason, a vibrator 25 is provided at the rear end of the outlet flow channel 34. The air outlet is located below the lower air vent 30. This design is based on the consideration that the lower air vent 30 is provided on the side of the outer body 10, and it is difficult for the material to directly block the lower air vent 30. The blockage can be removed by a simple air flow purge.

[0045] Secondly, in order to solve the problem of blockage of the ventilation window when it is in a static state, the vibrators 25 are arranged at one-to-one intervals at the rear end of the ventilation window.

[0046] In order to facilitate assembly and subsequent maintenance, an assembly 33 is provided in the opening 12, and the assembly 33 is threadedly connected to the opening 12. The assembly 33 is a blind plug, an air outlet pipe or a mesh plug. The figure shows an air outlet pipe and a blind plug. The blind plug is the most commonly used, and the air outlet pipe is used when a large airflow explosion is required.

[0047] When in use, the explosion nozzle of the present application is threadedly installed on the explosion pipe through the connection joint 13 at the bottom;

[0048] First, under normal explosion volume, the gas in the explosion pipe enters the chamber 11 through the first air outlet 31 on the gas column 22 and the second air outlet 32 ​​on the shell 21, and the gas in the chamber 11 respectively explodes the upper area and the lower area of ​​the sewage or waste gas through the upper air window 29 and the lower air window 30;

[0049] Under large explosion volume, compared with normal explosion volume, the air pressure will lift up the pressure regulating structure 26, that is, the metal ball, and a part of the air flow will blow to the vibrator 25, that is, the metal ring through the air outlet 24, and the metal ring will shake (vibrate), thereby improving the explosion effect under the vibration transmission.

[0050] Secondly, in the unblocking state, the process is similar to that of a large explosion volume, the difference is that the metal ring shakes (vibrates), and under the vibration propagation, the materials blocked in one or more of the first air outlet 31, the second air outlet 32, the upper air window 29 and / or the lower air window 30 are first vibrated and loosened, thereby achieving unblocking. After the unblocking is completed, the normal explosion volume or the large explosion volume is adjusted according to the explosion needs. The quality of the unblocking effect can be directly visually obtained on site, such as the explosion pool for sewage treatment, and the result of whether the unblocking is successful can also be obtained with the help of scientific measurement.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
