Description

Technical Field

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

[0002] Industrial wastewater refers to wastewater and waste liquid discharged during the process of production. It contains industrial production materials, intermediate products, by-products and pollutants generated during the production process that are lost with water. It is an important cause of environmental pollution. Industrial wastewater needs to be treated before it is discharged into the external environment. The conventional sewage treatment dosing device first adds wastewater treatment agents into the barrel, then adds tap water to dilute the agents, and stirs the diluted agents evenly with a manual stirrer, and then pumps the agents into the sedimentation tank through a metering pump. Obviously, the labor cost of using a manual stirrer is high, and the existing industrial water treatment devices mostly use drugs to treat sewage, but most of them are manual dosing, which will lead to low work efficiency and the dosage of manual dosing is difficult to control, so it is difficult to meet the large-scale and long-term sewage treatment needs. To this end, we propose an automatic dosing device for sewage treatment. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model provides a technical solution: an automatic dosing device for sewage treatment, comprising a mixing bin 1 and a weighing bin 11, wherein a flip seat 15 is arranged in the weighing bin 11, a material receiving frame 17 is installed in a mounting groove 16 of the flip seat 15 through a connecting mechanism, a weighing sensor 18 is arranged in the mounting groove 16, an ear seat 19 is arranged below one end of the flip seat 15, and specifically, the ear seat 19 is rotatably connected to the mixing bin 1.

[0018] A gear 2 is provided on the side of the ear seat 19, and a rack 21 is meshed on the lower side of the gear 2. The side of the rack 21 is connected to the telescopic rod of the electric telescopic rod 22 through a connecting rod. The side of the mixing bin 1 is connected to a flow meter 26 through a pipeline. A stirring mechanism 27 is provided in the mixing bin 1, and a water pump 29 is provided at the water outlet of the mixing bin 1.

[0019] By setting up the ear seat 19, the gear 2, the rack 21, the electric telescopic rod 22 and other structures for use in combination, the above-mentioned mechanisms can be used to drive the material receiving frame 17 to flip, so that the material inside the material receiving frame 17 can be automatically added to the mixing bin 1. This process does not require manual operation, effectively improving the processing efficiency of adding materials to the mixing bin 1, and bringing convenience to the mixing operation.

[0020] In the above solution, the weighing bin 11 is provided with an opening 12 on its side, and a protective cover 13 is provided outside the opening 12. The design of the protective cover 13 can prevent the material from being thrown out when the flip seat 15 rotates, and ensure that the material can be accurately added into the mixing bin 1.

[0021] In the above scheme, a feeding port 14 is provided on the top of the weighing bin 11. By arranging a flip seat 15, a mounting slot 16, a material receiving frame 17, a weighing sensor 18 and other structures in the weighing bin 11, the solid medicine added to the weighing bin 11 can be automatically weighed, so that the solid material added to the mixing bin 1 can be quantitatively controlled to achieve the purpose of accurately controlling the amount of medicine added, thereby improving the water treatment effect and being simple and convenient to operate.

[0022] In the above scheme, the connection mechanism includes a limit block 23 arranged on the upper side of the flip seat 15, and the side of the limit block 23 is connected to a plug rod 25 through a spring 24, and the other end of the plug rod 25 can be correspondingly inserted into the socket on the side of the material receiving frame 17.

[0023] In the above scheme, the stirring mechanism 27 includes a rotating shaft and a stirring paddle, and the bottom end of the rotating shaft is connected to a motor 28. After the solid medicine and the water source are added into the mixing bin 1, the motor 28 is started by a switch, and the motor 28 drives the rotating shaft and the stirring paddle to rotate to continuously stir and mix the materials.

[0024] In the above scheme, the outlet end of the water pump 29 is connected to the discharge pipe 3. After the mixing operation is completed, the material inside the mixing bin 1 is pumped out by the water pump 29 and added to the sewage through the discharge pipe 3 for sewage treatment.

[0025] The flow meter 26 adopts an electronic flow meter. In addition, by setting the flow meter 26, the liquid entering the mixing chamber 1 can be quantitatively controlled to ensure that the mixed liquid medicine is within a reasonable ratio range, thereby improving the quality of sewage treatment.

[0026] In the above scheme, the outer surface of the weighing bin 11 is provided with a display screen 31 and a controller 32. The weighing sensor 18 is used in conjunction with the display screen 31 and the controller 32. The display screen 31 can synchronously display the sensor data. When the material detected by the weighing sensor 18 reaches the calibrated range, the controller 32 receives feedback and issues a command. At this time, the electric telescopic rod 22 drives the rack 21 to move horizontally, and the rack 21 drives the gear 2 to rotate. The gear 2 drives the flip seat 15 to rotate a certain angle through the ear seat 19, so that the material inside the material receiving frame 17 is thrown into the mixing bin 1 from the inside.

[0027] Working principle:

[0028] When this type of automatic dosing device for sewage treatment is used, the solid medicine to be used is added from the feeding port 14 to the receiving frame 17 inside the mixing bin 1. In this process, the quality of the added medicine can be detected by the weighing sensor 18. When the material detected by the weighing sensor 18 reaches the calibrated range, the controller 32 receives feedback and issues a command. At this time, the electric telescopic rod 22 drives the rack 21 to move horizontally, and the rack 21 drives the gear 2 to rotate. The gear 2 drives the flip seat 15 to rotate a certain angle through the ear seat 19, so that the material inside the receiving frame 17 is thrown into the mixing bin 1 from the inside. Similarly, the flow meter 26 cooperates with the controller 32 to quantitatively control the liquid added to the mixing bin 1, and then the motor 28 is started by the switch. The motor 28 drives the rotating shaft and the stirring paddle to rotate to continuously stir and mix the material. After the mixing operation is completed, the material inside the mixing bin 1 is extracted by the water pump 29 and added to the sewage through the discharge pipe 3 for sewage treatment.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
