Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment spraying equipment, in particular to a spraying device for sewage treatment. Background Art

[0002] In microbial wastewater treatment, anaerobic biochemical treatment generally does not require aeration. The aeration tank is a place for the activated sludge to fully contact and provide sufficient oxygen for aerobic microorganisms. Simply put, aeration increases the DO value and stirring effect in the water. The aeration tank will produce a small amount of white, fragile foam through continuous aeration. This foam is non-sticky and will break and gradually disappear when exposed to sunlight. This is a normal phenomenon; Patent No. CN201821649941.8 discloses a spray device for sewage treatment, which is equipped with a detachable spray hood connected to the spray conduit, and can then change the structure of the spray hood to cope with different sewage treatment aeration tanks, avoiding the phenomenon of spray liquid outflow; However, when adjusting the spray hood on the periphery of the spray pipe used in sewage treatment, the staff needs to manually rotate the adjustment rod to adjust the distance between the spray hood and the nozzle, which is not convenient to adjust and has low efficiency. To this end, we propose a spray device for sewage treatment. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a spray device for sewage treatment.

[0004] The technical solution adopted by the utility model to solve the technical problem is a spray device for sewage treatment, comprising a shell and a pad, an external threaded pipe for adjustment is rotatably installed between the shell and the pad, and a ring sleeve for installing a spray cover is screwed on the outer circumference of the external threaded pipe, a worm wheel drivingly connected to the external threaded pipe is rotatably installed inside the shell, and a worm screw meshing with the worm wheel is rotatably installed inside the shell;

[0005] A vertical rod slidably connected to the ring sleeve is installed between the shell and the pad, and there are multiple groups of vertical rods. A pipe seat for connection is installed on the bottom surface of the pad. A nozzle for sewage treatment is installed at the end of the pipe seat away from the pad. A vertical pipe connected to the inner side of the external threaded pipe is installed between the pad and the shell, and a swivel joint connected to the vertical pipe is installed at one end of the external threaded pipe located on the inner side of the shell.

[0006] By adopting the above technical solution, when sewage is treated by the spraying equipment and the distance between the nozzle and the spray hood needs to be adjusted, since the spray hood is installed on the outer periphery of the ring sleeve, it is only necessary to rotate the worm on the inner side of the shell so that the worm and the worm wheel can be screwed together and drive the worm wheel to rotate. Then the worm wheel conveniently drives the external threaded pipe between the shell and the pad to rotate so that the external threaded pipe and the ring sleeve are screwed together. At the same time, since the vertical rod and the ring sleeve penetrate and slide each other, the ring sleeve can drive the spray hood to move, so that the distance between the spray hood and the nozzle can be adjusted electrically.

[0007] After adjusting the distance between the nozzle and the spray hood, the swivel joint on the inside of the shell can be used to support the external threaded pipe and facilitate the diversion of the spray liquid used in sewage treatment. The spray liquid is guided by the vertical pipe located on the inside of the external threaded pipe to the nozzle installed on the inside of the pipe seat at the bottom of the pad, so that the nozzle can easily spray the spray liquid into the sewage in the sewage pool, making it easier to treat it.

[0008] Specifically, the inner side of the ring sleeve is equipped with a ring sleeved and connected with the vertical rod, and there are multiple groups of rings.

[0009] By adopting the above technical solution, the collar and the vertical rod penetrate each other and are slidably connected, which makes it easy to reduce the damage to the collar caused by friction when the vertical rod and the collar slide against each other, and the collar is easy to disassemble, assemble and replace.

[0010] Specifically, a cover plate for maintenance is assembled on the top surface of the shell through bolts.

[0011] By adopting the above technical solution, the cover plate is easy to disassemble and assemble, and the structural components inside the shell are easy to maintain.

[0012] Specifically, a reducer drivingly connected to the worm is mounted on the outer side wall surface of the shell, and a waterproof motor is mounted on the power input end of the reducer.

[0013] By adopting the above technical solution, the waterproof motor can easily drive the worm inside the shell to rotate under the operation of the reducer, so that the worm can mesh with the worm wheel and drive the worm wheel to rotate.

[0014] Specifically, the outer side wall surface of the shell is equipped with a branch pipe connected to the swivel joint.

[0015] By adopting the above technical solution, the branch pipes can be easily connected to the external pipes, so that the spray liquid used for sewage treatment can be easily transported to the rotary joint.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application is designed through a worm, a worm wheel, a pipe seat, a nozzle, an externally threaded pipe, a vertical rod and a ring sleeve. When sewage is treated with a spray device and the distance between the nozzle and the spray hood needs to be adjusted, since the spray hood is installed on the outer periphery of the ring sleeve, it is only necessary to rotate the worm on the inner side of the shell so that the worm and the worm wheel can be screwed together and drive the worm wheel to rotate. Then the worm wheel conveniently drives the externally threaded pipe between the shell and the pad to rotate so that the externally threaded pipe and the ring sleeve are screwed together. At the same time, since the vertical rod and the ring sleeve penetrate and slide with each other, the ring sleeve can drive the spray hood to move, so that the distance between the spray hood and the nozzle can be adjusted electrically.

[0018] 2. The technical solution of the present application adopts the design of a swivel joint, a vertical pipe and a pad. After adjusting the distance between the nozzle and the spray hood, the swivel joint on the inside of the shell can be used to support the external threaded pipe and facilitate the diversion of the spray liquid used in sewage treatment. The spray liquid is guided by the vertical pipe located on the inside of the external threaded pipe to the nozzle installed on the inside of the pipe seat at the bottom of the pad, so that the nozzle can conveniently spray the spray liquid into the sewage in the sewage pool, so as to facilitate its treatment.

[0026] When in use, when the spray equipment is used to treat sewage, and the distance between the nozzle 5 and the spray hood needs to be adjusted, since the spray hood is installed on the outer periphery of the ring sleeve 7, it is only necessary to rotate the worm 9 inside the shell 1 so that the worm 9 can be screwed with the worm wheel 8 and drive the worm wheel 8 to rotate. Then, the worm wheel 8 conveniently drives the external threaded pipe 6 between the shell 1 and the pad 3 to rotate, so that the external threaded pipe 6 and the ring sleeve 7 are screwed with each other. At the same time, since the vertical rod 2 and the ring sleeve 7 penetrate and slide with each other, the ring sleeve 7 can drive the spray hood to move, so that the distance between the spray hood and the nozzle 5 can be adjusted electrically.

[0027] After adjusting the distance between the nozzle 5 and the spray hood, the swivel joint 13 on the inner side of the shell 1 can be used to support the external threaded pipe 6 and facilitate the diversion of the spray liquid used in sewage treatment. The spray liquid is guided by the vertical pipe 12 located on the inner side of the external threaded pipe 6 to conveniently transport the spray liquid to the nozzle 5 installed on the inner side of the pipe seat 4 at the bottom of the pad 3, so that the nozzle 5 can conveniently spray the spray liquid into the sewage in the sewage pool, so as to facilitate its treatment.

[0028] like Figure 1 and Figure 3 As shown, the inner side of the ring sleeve 7 is equipped with a sleeve ring 16 which is sleeved and connected with the vertical rod 2, and there are multiple groups of sleeve rings 16.

[0029] When in use, the collar 16 and the vertical rod 2 penetrate each other and are slidably connected, so as to reduce the damage to the ring sleeve 7 caused by friction when the vertical rod 2 and the ring sleeve 7 slide against each other, and the collar 16 is easy to disassemble, assemble and replace.

[0030] like Figure 1 and Figure 2 As shown, a cover plate 15 for maintenance is assembled on the top surface of the housing 1 by means of bolts.

[0031] When in use, the cover plate 15 is easy to disassemble and assemble, so that the structural components inside the shell 1 can be easily maintained.

[0032] like Figure 1 and Figure 2 As shown, a reducer 10 drivingly connected to the worm 9 is mounted on the outer wall surface of the housing 1 , and a waterproof motor 11 is mounted on the power input end of the reducer 10 .

[0033] When in use, the waterproof motor 11 is operated to drive the worm 9 inside the housing 1 to rotate under the operation of the reducer 10, so that the worm 9 can mesh with the worm wheel 8 and drive the worm wheel 8 to rotate.

[0034] like Figure 1 and Figure 2 As shown, a branch pipe 14 connected to the swivel joint 13 is assembled on the outer wall surface of the housing 1 .

[0035] When in use, the branch pipe 14 is conveniently connected to the external pipeline, so as to conveniently transport the spray liquid used for sewage treatment to the rotary joint 13 .

[0036] The working principle and use process of the utility model are as follows: when in use, first install the corresponding structural components in the appropriate position. When using the spray equipment to treat sewage, and when it is necessary to adjust the distance between the nozzle 5 and the spray cover, since the spray cover is installed on the outer periphery of the ring sleeve 7, then it is only necessary to operate the waterproof motor 11 on the outer side of the shell 1, and conveniently drive the worm 9 on the inner side of the shell 1 to rotate under the operation of the reducer 10, so that the worm 9 can mesh with the worm wheel 8 and drive the worm wheel 8 to rotate, and then the worm wheel 8 conveniently drives the external threaded pipe 6 between the shell 1 and the pad 3 to rotate, so that the external threaded pipe 6 and the ring sleeve 7 are mutually screwed. At the same time, since the vertical rod 2 and the ring sleeve 7 penetrate each other and slide, the ring sleeve 7 can drive the spray hood to move, which is convenient for adjusting the distance between the spray hood and the nozzle 5 by electric means. After the distance between the nozzle 5 and the spray hood is adjusted, the swivel joint 13 on the inner side of the shell 1 can be used to support the external threaded pipe 6 and facilitate the diversion of the spray liquid used in sewage treatment. After being guided by the vertical pipe 12 located on the inner side of the external threaded pipe 6, the spray liquid is conveniently transported to the nozzle 5 installed on the inner side of the pipe seat 4 at the bottom of the pad 3, so that the nozzle 5 can conveniently spray the spray liquid into the sewage in the sewage pool, so as to facilitate its treatment.
