Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a novel automatic chemical dosing device for wastewater treatment. Background Art

[0002] The automatic chemical dosing device for wastewater treatment is an important water treatment equipment. Its main function is to automatically add an appropriate amount of chemical agents to the wastewater according to the water quality and process requirements during the wastewater treatment process, so as to improve the water quality or meet specific treatment requirements. In the traditional wastewater treatment field, it is often necessary to manually mix and dilute dry powder chemical agents with water or liquid chemical agents and then pump them into the wastewater treatment equipment.

There are three drain ports 9 on the side of the mixing tank 1 that penetrate through chamber one 4, chamber two 5, and chamber three 6, and the drain ports 9 are arranged between the first filter screen 8 and the bottom end face of the mixing tank 1; a flow port 3 is provided at the bottom of the partition plate 2 to facilitate the flow of the mixed chemicals in chamber one 4, chamber two 5, and chamber three 6.

[0045] Chamber one 4 is mainly used for dissolving dry chemicals, chamber two 5 is used for the continuous ripening of the chemicals, and chamber three 6 functions to continuously stir and temporarily store the mixed chemical liquid.

[0046] To facilitate the daily cleaning and maintenance of the equipment, a first filter screen 8 is provided in each chamber to isolate and block some particulate matters or insoluble substances to prevent them from depositing and falling to the bottom of the mixing tank 1. During daily maintenance, the first filter screen 8 can be removed for cleaning to remove most of the dirt.

The stirring rod 702 on the stirring device 7 corresponding to the first chamber 4, the second chamber 5, and the third chamber 6 extends into the corresponding chamber interior.

[0049] The stirring device 7 mainly uses the first stirring motor 701 to drive the stirring rod 702 and the stirring blades 703 to continuously rotate to stir the medicament in each chamber to improve the solubility.

[0050] The mixing tank 1 is also provided with a dry powder feeding device 10, a water injection pipe 11, and a medicine pumping device 12. The water injection pipe 11 is connected to an external water injection or liquid medicament pumping device, and injects liquid into the first chamber 4 through the upper part of the first chamber 4. The dry powder feeding device 10 is used to put dry powder medicament into the first chamber 4 for stirring and mixing. The medicine pumping device 12 is connected to the third chamber 6 through pipe fittings and is used to pump the stirred and mixed medicament into the wastewater treatment equipment.

[0051] The dry powder feeding device 10 includes a stirring and feeding component 1001 and a flushing and filtering component 1002. The flushing and filtering component 1002 is connected to the water injection pipe 11. The stirring and feeding component 1001 processes the dry powder medicament and sends it into the flushing and filtering component 1002, and then the liquid conveyed by the water injection pipe 11 sends the dry powder medicament into the first chamber 4 for stirring and mixing;

[0052] The flushing and filtering component 1002 includes a feeding cup 1002a, a transparent top cover 1002b in an inverted cup shape structure, and a second filter screen 1002c. The lower part of the feeding cup 1002a is communicated with the chamber of the first chamber 4. The upper part of the feeding cup 1002a is connected to the transparent top cover 1002b in a threaded connection manner, and a through hole convenient for connecting with the stirring and feeding component 1001 is provided on the transparent top cover 1002b.

[0053] The stirring and feeding component 1001 includes a second stirring motor 1001a, a feeding funnel 1001b, a spiral shaft 1001c, a vibrator 1001d, a vertical plate 1001e, and a medicine conveying pipe 1001f;

[0054] The spiral shaft 1001c is arranged at the bottom of the feeding funnel 1001b. One end of the spiral shaft 1001c is connected to the rotating shaft of the second stirring motor 1001a, and the other end passes through the side wall of the feeding funnel 1001b and extends into the transparent top cover 1002b. The medicine conveying pipe 1001f is sleeved outside the spiral shaft 1001c. One end of the medicine conveying pipe 1001f is connected to the transparent top cover 1002b and the other end is connected to the feeding funnel 1001b, which is convenient for the spiral shaft 1001c to convey the dry powder medicament into the feeding cup 1002a;

[0055] The vibrator 1001d is arranged on the outer wall below the feeding hopper 1001b and is used to vibrate to make the dry powder agent fall to the position of the spiral shaft 1001c.

[0056] The stirring and feeding assembly 1001 is further provided with a material turning assembly 1001g. The material turning assembly 1001g is used to turn and mix the dry powder agent placed in the feeding hopper 1001b to ensure that the dry powder agent can smoothly fall to the position of the spiral shaft 1001c. The material turning assembly 1001g includes a turning and mixing motor 1001ga arranged on the outer wall below the feeding hopper 1001b and a turning and mixing rod 1001gb with blades. One end of the turning and mixing rod 1001gb is connected to the rotating shaft of the turning and mixing motor 1001ga, and the other end of the turning and mixing rod 1001gb and the blades on the turning and mixing rod 1001gb are arranged inside the feeding hopper 1001b.

[0057] The dry powder agent is put into the feeding hopper 1001b manually or by a hollow material suction device. Then, it is necessary to ensure that the dry powder agent in the feeding hopper 1001b is always in a full-load state. Then, the turning and mixing motor 1001ga drives the turning and mixing rod 1001gb to rotate to turn and mix the dry powder agent in the feeding hopper 1001b, which plays a role in preventing agglomeration and facilitating the agent to enter the position of the spiral shaft 1001c. Similarly, the vibrator 1001d promotes the dry powder agent to enter the position of the spiral shaft 1001c through high-frequency vibration, achieving the purpose of continuously conveying the dry powder agent. When the dry powder agent reaches the position of the rotating shaft 1001c, the rotating shaft 1001c obtains the rotating power through the stirring motor two 1001a and continuously conveys the dry powder agent into the flushing and filtering assembly 1002. After the dry powder agent enters the flushing and filtering assembly 1002, it falls onto the filter screen 1002c of the feeding cup 1002. At this time, the liquid agent or dilution water after flow adjustment from the water injection pipe 11 flushes the dry powder agent falling on the filter screen 1002c and flushes it into the chamber one 4. Larger agglomerated agents are filtered here by the filter screen 1002c to prevent them from falling into the chamber one 4. And in order to facilitate observing the situation of the agglomerated agents remaining on the filter screen 1002c, a transparent top cover 1002b for easy observation is provided.

[0058] Specifically, the pump drug device 12 includes a diaphragm metering pump 1201 and a drug delivery pipe 1202. The liquid inlet of the diaphragm metering pump 1201 is connected to the inside of the chamber three 6 through the drug delivery pipe 1202.

[0059] In this embodiment, in order to accurately pump the mixed medicament into the wastewater treatment equipment, a diaphragm metering pump 1201 is designed to communicate with chamber three 6 through a medicine delivery pipe 1202, facilitating the extraction of the mixed medicament in chamber three 6. Of course, in order to prevent the pump medicine device 12 from malfunctioning and causing the inability to continuously pump the medicament to the wastewater treatment equipment, two pump medicine devices 12 can be provided here.

[0060] Specifically, an overflow pipe 13 is further provided in chamber one 4. One end of the overflow pipe 13 is arranged at the upper part of chamber one 4, and the other end passes through the outer wall of chamber one 4 and extends to the outside to be connected to an external leak liquid receiving device, preventing the liquid level in chamber one 4 from being too high and overflowing to the outside of the equipment, causing pollution. An observation port is provided on each of chamber one 4, chamber two 5, and chamber three 6, and a dust-proof cover is provided on the observation port. A liquid level sensor is further provided on chamber three 6 to detect the liquid level of the liquid medicine in chamber three 6. A funnel cover is movably provided on the upper part of the feeding funnel 1001b, and the lower part of the feeding funnel 1001b is connected to the upper end surface of the mixing tank 1 through two symmetrically arranged vertical plates 1001e. Each drain port 9 is connected to an external waste liquid holding device through a water pipe.

[0061] Working principle: First, the dry powder medicament is put into the feeding funnel 1001b manually or by a hollow suction device. Then, it is necessary to ensure that the dry powder medicament in the feeding funnel 1001b is always in a full-load state. Then, the stirring motor 1001ga drives the stirring rod 1001gb to rotate to stir the dry powder medicament in the feeding funnel 1001b, which plays a role in preventing agglomeration and facilitating the medicament to enter the position of the spiral shaft 1001c. Similarly, the vibrator 1001d promotes the dry powder medicament to enter the position of the spiral shaft 1001c through high-frequency vibration, achieving the purpose of continuously conveying the dry powder medicament. When the dry powder medicament reaches the position of the rotating shaft 1001c, the rotating shaft 1001c obtains the rotating power through the stirring motor two 1001a and continuously conveys the dry powder medicament to the flushing and filtering assembly 1002. After the dry powder medicament enters the flushing and filtering assembly 1002, it falls onto the filter screen 1002c of the feeding cup 1002. At this time, the liquid medicament or dilution water after flow adjustment from the water injection pipe 11 flushes the dry powder medicament falling on the filter screen 1002c and flushes it into chamber one 4. Larger agglomerated medicaments are filtered by the filter screen 1002c here to prevent them from falling into chamber one 4. And in order to facilitate observing the situation of the remaining agglomerated medicaments on the filter screen 1002c, a transparent top cover 1002b for easy observation is provided.

[0062] After the dry powder medicament enters the first chamber 4, it is stirred and mixed. Since the mixed medicament is continuously consumed, the mixed medicament in the first chamber 4 will flow from the circulation port 3 into the second chamber 5 and the chamber 6. Similarly, the stirring devices 7 on the second chamber 5 and the third chamber 6 continuously stir the medicament in the corresponding chambers to ensure the solubility of the medicament.

[0063] When cleaning and maintaining the equipment, the liquid in the three chambers is drained through the drain port 9, and then the second filter screen 1002c is taken out for cleaning. Compared with the situation where debris particles are deposited at the bottom of the mixing tank 1, this solution can effectively reduce the cleaning difficulty and improve the cleaning efficiency through the setting of the second filter screen 1002c.
