Description

Technical Field

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

[0002] The process of sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. In the sewage treatment process, it is often necessary to react with sewage through chemicals, which requires the mixing and processing of multiple chemicals.

[0003] In the prior art, when adding and mixing drugs, some drugs are liquid. At this time, the liquid drugs are directly added completely into the stirring device. After stirring, the drugs and sewage can be evenly mixed. Some drugs are powders. If the materials are added and stirred at one time, when the powder is added into the water quickly and in large quantities, the local powder concentration may be too high, and there is no time to fully mix and wet with water. This will easily cause the powder to agglomerate and form lumps, which will easily affect the adding and mixing effect. If the workers add the powder slowly little by little, it will be troublesome. Therefore, an improved sewage treatment agent mixing device is needed to address this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a sewage treatment agent mixing device to solve the problems raised in the above background technology.

The power output shaft end of the electric motor is transmission-connected with the power input shaft of the reducer, and the power output shaft of the reducer is transmission-connected with the transmission sleeve. The transmission sleeve is movably sleeved on the outer surface of the rotating rod. The transmission of this device The mechanism can conveniently drive the rotating rod to rotate, thereby driving the stirring rod to rotate and stir, and correspondingly can also drive the intermittent feeding mechanism to rotate, so as to intermittently add powder agents; these powder agents can be powder agents required for sewage treatment such as polyaluminum chloride or polyacrylamide; and the power transmission of the device is transmitted by a transmission sleeve sleeved on the outer surface of the transmission rod, so that when removing the top cover, the top cover, the reducer, the motor, and the transmission sleeve can be directly lifted upwards, and the disassembly of the top cover and all the equipment on the top cover can be completed, and the power connection of the device will not be blocked.

[0007] Preferably, through holes are provided on both sides of the upper end of the top cover, through which the storage bin of the gap feeding mechanism can be conveniently passed, so that the medicine can be conveniently replenished into the storage bin without opening the top cover.

[0008] Preferably, a plurality of buckles are movably provided at the four corners of the outer surface of the mixing tank through a rotating shaft, and a locking screw is provided between the buckle and the top cover. The top cover can be fixed to the upper end of the mixing tank by the buckle and the locking screw.

The transmission rod 12 is fixedly provided on the upper end of the rotating rod 4, and the transmission sleeve 13 is movably provided on the middle part of the inner side of the top cover 2 through a bearing. The reducer 14 is fixedly provided on the middle part of the upper end of the top cover 2, and the motor 15 is fixedly provided on one side of the upper end of the top cover 2. The power output shaft end of the motor 15 is transmission-connected with the power input shaft of the reducer 14, and the power output shaft of the reducer 14 is transmission-connected with the transmission sleeve 13. The transmission sleeve 13 is movably sleeved on the outer surface of the rotating rod 4 The transmission mechanism of the device can conveniently drive the rotating rod 4 to rotate, thereby driving the stirring rod 5 to rotate and stir, and correspondingly can also drive the intermittent feeding mechanism to rotate, so as to intermittently add powder agents; these powder agents can be powder agents required for sewage treatment such as polyaluminum chloride or polyacrylamide; and the power transmission of the device is transmitted by the transmission sleeve 13 sleeved on the outer surface of the transmission rod 12, so that when disassembling the top cover 2, the top cover 2, the reducer 14, the motor 15, and the transmission sleeve 13 can be directly lifted upwards, and the disassembly of the top cover 2 and all the equipment on the top cover 2 can be completed, and the power connection of the device will not be blocked;

The top cover 2 can be fixed to the upper end of the mixing tank 1 by the buckle 17 and the locking screw 18.

The sewage to be doped can be conveniently introduced into the mixing tank 1 through the liquid inlet pipe 19, and the sewage after doped can be conveniently discharged through the liquid outlet pipe 20. Valves should be installed at one end of the water inlet pipe and the water outlet pipe to control whether the water inlet pipe and the water outlet pipe are connected. However, this is a conventional method in the prior art, so this application document will not describe the installation method of such valves.

[0026] The diameter of the first pulley 10 is smaller than that of the second pulley 11. The first pulley 10 with a smaller diameter drives the second pulley 11 to reduce speed, so that the rotation speed of the rotating disk 8 is lower than that of the stirring rod 5. The stirring rod 5 rotates several times before the rotating disk 8 rotates one circle to perform a feeding operation.

[0027] Working principle: When using the device, the sewage to be doped can be conveniently introduced into the mixing tank 1 through the liquid inlet pipe 19, and the sewage after doped can be conveniently discharged through the liquid outlet pipe 20. When dosing the sewage, the powder medicine can be placed in the storage bin 6, and then the motor 15 and the reducer 14 are decelerated and then drive the rotating rod 4 and the stirring rod 5 to rotate, so that the sewage can be stirred to facilitate the mixing of the medicine;

[0028] When the rotating rod 4 rotates, the second pulley 11 is driven to rotate through the first pulley 10 and the transmission belt, so that the rotating disk 8 can be rotated. As the rotating disk 8 rotates, only when the through groove 9 on the surface of the rotating disk 8 is aligned with the discharge port 7 at the lower end of the storage bin 6, the medicine inside the storage bin 6 will fall into the mixing tank 1 under the force of gravity. When the through groove 9 and the discharge port 7 are misaligned with the rotation of the rotating disk 8, the dosing will be stopped. In this way, the rotating disk 8 can be rotated once each time to dosing. In this way, when adding powder medicine in sewage treatment, automatic intermittent addition can be performed, so that the powder is added more evenly, and it is not easy to agglomerate, and there is no need to add it slowly manually, thereby improving the mixing effect of the medicine during sewage treatment;

[0029] When the device is in use, the power transmission is transmitted by the transmission sleeve 13 sleeved on the outer surface of the transmission rod 12. In this way, when removing the top cover 2, the top cover 2, the reducer 14, the motor 15, and the transmission sleeve 13 can be directly lifted upward to complete the disassembly of the top cover 2 and all the equipment on the top cover 2. The power connection of the device will not be hindered, so the top cover 2 can be easily disassembled to inspect all the parts inside the mixing tank 1.
