Description

Technical Field

[0001] This utility model relates to the field of jet aerator technology, specifically a disc-type jet aerator. Background Technology

[0002] The commonly used disc jet aerator consists of two nested disc-shaped cavities, with multiple sets of concentric nozzles corresponding to the circumference of each cavity. Circulating water is ejected at high speed from the inner cavity through the nozzles and mixes with the pressurized air in the outer cavity, forming a gas-liquid mixture by utilizing the jet shearing of the air.

[0003] Publication number CN212712948U discloses a high dissolved oxygen disc jet aerator. This patent extends part of the inner nozzle into the outer nozzle, causing water ejected from the inner nozzle to create negative pressure in the mixing chamber. This negative pressure draws air from the air inlet chamber into the mixing chamber, increasing the dissolved oxygen content of the water in the mixing chamber and expanding the spray range of the outer nozzle, thus broadening the adjustable range of dissolved oxygen content. This provides high resistance to shock loads in SBR systems treating high ammonia nitrogen wastewater. The disc-shaped outer and inner sleeves form an arc-shaped air inlet channel, facilitating air entry into the mixing chamber and increasing the dissolved oxygen content of the water. The inlet chamber is elliptical, eliminating dead zones and making it easy to clean when impurities are present, preventing clogging. However, this patent still has the following problems in practical use:

[0004] Air from the intake chamber enters the mixing chamber under negative pressure, increasing the dissolved oxygen content of the water in the mixing chamber and expanding the spray range of the external nozzles. This broadens the adjustable range of dissolved oxygen content. For high ammonia nitrogen wastewater treatment, the SBR has high resistance to shock loads. However, in actual use, the aerator is entirely underwater. Wastewater contains various impurities, and when the aerator is used underwater for extended periods, impurities accumulate on both the inside and outside. Disassembling the aerator during use is inconvenient, as is regular cleaning. Without cleaning, the accumulated impurities create resistance to water flow, affecting the aeration effect.

[0005] A disc jet aerator is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a disc jet aerator to solve the problems mentioned in the background art. Currently, air from the inlet chamber enters the mixing chamber under negative pressure, increasing the dissolved oxygen content in the mixing chamber and expanding the spray range of the external nozzles, thus broadening the adjustable range of dissolved oxygen content. This provides high resistance to shock loads in SBR systems used for treating high ammonia nitrogen wastewater. However, in actual use, the aerator is entirely underwater. In wastewater treatment, various impurities are present in the wastewater. When the aerator is used underwater for a long time, impurities accumulate inside and outside. Disassembly and regular cleaning of the aerator are inconvenient during use. Without cleaning, the accumulated impurities create resistance to water flow, affecting the aeration effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a disc jet aerator, including a shell;

[0008] The outer shell has several spray pipes extending through it, and an inner shell is provided inside the outer shell. Several spray nozzles are connected through it to the outer side of the inner shell. An air inlet pipe is connected through it to the top of the outer shell, and a water inlet pipe is connected through it to the bottom of the inner shell.

[0009] Also includes:

[0010] The bottom of the outer shell is symmetrically provided with two sets of support components;

[0011] The support assembly includes two sets of fixed seats symmetrically installed at the bottom of the housing, and the fixed seats have connecting grooves inside, and the connecting grooves are provided with support legs.

[0012] The fixed base has a positioning pin inside the lower part, and a number of positioning holes are opened through the upper part of one side of the support leg, and the positioning pin is inserted into the positioning holes.

[0013] Preferably, a fixing frame is fixedly installed on one side of the fixing base above the positioning pin, and a positioning rod is slidably connected inside the fixing frame. A positioning groove is opened on the top side of the positioning pin, and the positioning rod is engaged with the positioning groove.

[0014] Preferably, a movable frame is fixedly installed on the top of the positioning rod, and a rotating rod is rotatably connected to one side of the fixed seat above the fixed frame. A rotating frame is fixedly installed on one end of the rotating rod, and a torsion spring is sleeved on the outer side of the rotating rod. The two ends of the torsion spring are fixedly connected to the rotating frame and the fixed seat, respectively.

[0015] Preferably, a rotating rod is fixedly installed on the top of the rotating frame, and a column is fixedly installed on the lower side of the rotating frame away from the fixed seat, and the column is slidably connected to the movable frame.

[0016] Preferably, a limiting frame is fixedly installed at the end of the positioning pin away from the positioning rod, and a fixing seat is fixedly installed on one side of the limiting frame with a plug rod, and an installation hole is opened through the upper side of one side of the limiting frame, and the plug rod is inserted into the installation hole.

[0017] Preferably, the insert has an installation groove on one side inside, and limit rods are symmetrically slidably connected to both sides of the installation groove inside the insert.

[0018] Preferably, a telescopic spring is fitted on the outer side of each of the two limiting rods, and one end of the telescopic spring is fixedly connected to the mounting groove, and a movable block is fixedly installed on the other end of the telescopic spring. The movable block is slidably connected to the mounting groove and fixedly connected to the limiting rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this disc jet aerator allows for the complete disassembly of the outer shell, facilitating cleaning by lifting the entire shell and avoiding any impact on aeration efficiency. It also facilitates the assembly and disassembly of the outer shell, improving convenience and practicality. The specific details are as follows:

[0020] 1. Wastewater can enter the inner shell through the inlet pipe, and air can enter the outer shell through the air inlet pipe. After entering the outer shell, the wastewater mixes with the air to form a gas-liquid mixture, which is then sprayed out through the spray pipe. When the outer shell needs to be disassembled, the support legs are fixed in the treatment equipment. The entire support assembly is made of stainless steel, which has good corrosion resistance. During disassembly, the rotating rod is manually rotated, which causes the torsion spring to deform, thus rotating the rotating frame. After the rotating frame rotates, the column can rotate circumferentially. After the column rotates circumferentially, it can lift the movable frame by abutting against it, which can lift the positioning rod, causing the positioning pin to lose its limit, and the casing can be removed. The lower positioning pin removes the limiting position of the fixing seat, allowing the outer shell to be removed. When installing the outer shell, the fixing seat is placed on the support leg. The installation height of the outer shell can be adjusted as needed to align the positioning pin with the corresponding positioning hole. The positioning pin is then passed through the fixing seat and the positioning hole to position the fixing seat. After the positioning pin is inserted, the rotating rod is rotated, and one end of the positioning pin fits against the fixing seat, aligning the positioning rod with the positioning groove. The rotating rod can then be released, and the positioning rod returns to its original position under the action of the torsion spring, engaging with the positioning groove. This allows the positioning pin to be positioned, facilitating the disassembly and cleaning of the outer shell. It also allows for adjustment of the installation height of the outer shell, improving its practicality.

[0021] 2. During the installation of the outer casing, after the positioning pin is inserted into the fixing seat, the limiting bracket is placed over the outside of the insertion rod. As the positioning pin is inserted, the two limiting rods come into contact with the limiting bracket. As the positioning pin continues to be inserted, since one end of each limiting rod is spherical, the inner wall of the mounting hole can push the limiting rod to move, thus stretching the telescopic spring. When the positioning pin is inserted and fits against the fixing seat, the two limiting rods can extend out of the mounting hole. Under the action of the telescopic spring, the limiting rods return to their original position, which can initially limit the positioning pin. At this time, the positioning groove on the positioning pin is aligned with the positioning rod, avoiding the need to continuously adjust the position of the positioning pin after insertion. This facilitates the positioning of the positioning pin, improves the efficiency of disassembly and assembly of the outer casing, and enhances its practicality. Attached Figure Description

[0030] A fixing bracket 206 is fixedly installed on one side of the fixing base 201 above the positioning pin 204. A positioning rod 207 is slidably connected inside the fixing bracket 206. A positioning groove 208 is opened on one side of the top of the positioning pin 204, and the positioning rod 207 is engaged with the positioning groove 208 to position the positioning pin 204. A movable bracket 209 is fixedly installed on the top of the positioning rod 207. A rotating rod 210 is rotatably connected on one side of the fixing base 201 above the fixing bracket 206. A rotating frame 212 is fixedly installed at one end of the rotating rod 210, and a torsion spring 211 is sleeved on the outer side of the rotating rod 210. The two ends of the torsion spring 211 are fixedly connected to the rotating frame 212 and the fixed base 201 respectively, so that the rotating rod 210 can automatically return to its original position after rotation. A rotating rod 213 is fixedly installed on the top of the rotating frame 212, and a column rod 214 is fixedly installed on the lower side of the rotating frame 212 away from the fixed base 201. The column rod 214 is slidably connected to the movable frame 209, so that the column rod 213... The 14-circular rotation can move the positioning rod 207. A limit bracket 215 is fixedly installed at the end of the positioning pin 204 away from the positioning rod 207. A rod 216 is fixedly installed on one side of the limit bracket 215, and a mounting hole 217 is provided above one side of the limit bracket 215. The rod 216 is inserted into the mounting hole 217 to limit the angle of the positioning rod 207. A mounting groove 218 is provided on one side of the rod 216, and the inside of the rod 216 is located in the mounting groove. Limiting rods 219 are symmetrically slidably connected on both sides of the groove 218 to limit the position of the positioning pin 204. A telescopic spring 220 is sleeved on the outer side of each of the two limiting rods 219. One end of the telescopic spring 220 is fixedly connected to the mounting groove 218, and a movable block 221 is fixedly installed on the other end of the telescopic spring 220. The movable block 221 is slidably connected to the mounting groove 218 and fixedly connected to the limiting rod 219, so that the limiting rod 219 can automatically reset after moving.

[0031] Working principle: Before using this disc jet aerator, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, wastewater can enter the inner shell 102 through the inlet pipe 103, and air can enter the outer shell 1 through the air inlet pipe 105. After entering the outer shell 1, the wastewater mixes with the air to form a gas-liquid mixture, which is then sprayed out through the spray pipe 101. When the outer shell 1 needs to be disassembled, the support leg 202 is fixed in the treatment equipment. The support assembly 2 is made entirely of stainless steel, which has good corrosion resistance. When disassembling, the rotating rod 213 is manually rotated, which drives the rotating rod 210 to rotate, causing the torsion spring 211 to deform and the rotating frame 212 to rotate. After the rotating frame 212 rotates, the column rod 214 can rotate circumferentially. After the column rod 214 rotates circumferentially, it can lift the movable frame 209 by abutting against it, which can lift the positioning rod 207, causing the positioning pin 204 to lose its limit and be removed. This causes the fixing base 201 to lose its limit, allowing the outer shell 1 to be removed. When installing the outer shell 1, the fixing base 201 is placed on the support leg 202. The installation height of the outer shell 1 can be adjusted as needed to align the positioning pin 204 with the corresponding positioning hole 205. The positioning pin 204 is passed through the fixing base 201 and the positioning hole 205 to position the fixing base 201. After the positioning pin 204 is inserted, the rotating rod 213 is rotated, and one end of the positioning pin 204 is in contact with the fixing base 201, aligning the positioning rod 207 with the positioning groove 208. Then the rotating rod 213 can be released, and under the action of the torsion spring 211, the positioning rod 207 is reset and engages with the positioning groove 208, allowing the positioning pin 204 to be positioned. This facilitates the disassembly and cleaning of the outer shell 1, and allows for adjustment of the installation height of the outer shell 1, improving its practicality.

[0032] When installing the outer casing 1, after the positioning pin 204 is inserted into the fixing base 201, the limiting bracket 215 is fitted over the insertion rod 216. As the positioning pin 204 is inserted, the two limiting rods 219 come into contact with the limiting bracket 215. After the positioning pin 204 is further inserted, since one end of the two limiting rods 219 is spherical, the inner wall of the mounting hole 217 can push the limiting rods 219 to move, which allows the telescopic spring 220 to be stretched. When the positioning pin 204 is inserted and fits against the fixing base 201, the two limiting rods 219 can extend out of the mounting hole 217. Under the action of the telescopic spring 220, the limiting rods 219 are reset, which can initially limit the positioning pin 204. At this time, the positioning groove 208 on the positioning pin 204 is aligned with the positioning rod 207, avoiding the need to continuously adjust the position of the positioning pin 204 after insertion, facilitating the positioning of the positioning pin 204, improving the disassembly and assembly efficiency of the outer casing 1, and enhancing its practicality.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
