Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a drug dissolving device for wastewater treatment. Background Technology

[0002] Wastewater generally refers to sewage discharged from domestic and industrial sources that has been polluted to a certain extent. Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly entering the daily lives of ordinary people. There are three types of wastewater treatment: physical treatment, chemical treatment, and biological treatment. In chemical treatment, the treatment units based on adding agents to produce chemical reactions include: coagulation, neutralization, and oxidation-reduction.

[0003] Existing wastewater treatment chemicals are all in powder form. During use, they need to be dissolved in a dissolving device before being added to the solution. Currently, a stirring shaft is usually used to accelerate the dissolution process, but the dissolution rate still needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a drug dissolving device for wastewater treatment, addressing the problem mentioned in the background section that the dissolution rate of drugs stirred by a stirring shaft still needs improvement. To achieve the above objective, this invention provides the following technical solution:

[0005] A drug dissolving device for wastewater treatment includes a dissolving cylinder, which comprises a cylinder body. A top cover is fixedly connected to the upper end of the cylinder body, and a bottom plate is fixedly connected to the lower end of the cylinder body. A stirring mechanism and a feeding mechanism for quantitatively adding drugs are provided on the top cover. An air blowing mechanism for introducing air into the dissolving cylinder is provided on the bottom plate. A sealing mechanism for sealing the dissolving cylinder is provided below the bottom plate. A water pipe for adding water into the dissolving cylinder is provided on the side wall of the cylinder body, and an electrically controlled valve is provided on the water pipe.

[0007] Preferably, the feeding mechanism includes a hopper fixedly connected to the top cover, a hydraulic rod fixedly connected to the hopper, a connecting rod fixedly connected to the movable end of the hydraulic rod, and two stops fixedly connected in parallel on the connecting rod, the outer diameter of the stops being equal to the inner diameter of the lower section of the hopper.

[0008] Preferably, the air blowing mechanism includes an annular tube fixedly connected to the base plate, a plurality of radial tubes uniformly fixedly connected to the inner side of the annular tube, a plurality of air outlet holes uniformly opened on the annular tube and the radial tubes, an air inlet pipe fixedly connected to the outer side of the annular tube, a one-way valve connected to the air inlet pipe, an air pump fixedly connected to the end of the air inlet pipe, and a heating component capable of heating air provided at the air inlet of the air pump.

[0009] Preferably, the heating assembly includes a heating chamber fixedly connected to the air inlet of the air pump, and a plurality of resistance wires are uniformly fixedly connected in the heating chamber.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this invention, an air pump is installed to pump external air into the annular and radial pipes, and discharge it into the water through the air outlets on the annular and radial pipes, causing bubbles to rise in the water. Compared with only a stirring mechanism, this can further enhance the flow of water, thereby greatly improving the dissolution rate of the drug.

[0013] In this invention, the heating component can heat the air pumped in by the air pump, so that the air carries a certain amount of heat, thereby heating the water at the bottom, causing the water to generate hot and cold convection, enhancing the water flow, and raising the overall water temperature, which can further accelerate the dissolution of the drug.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution:

[0022] A drug dissolving device for wastewater treatment includes a dissolving cylinder 1, which includes a cylinder body 101. A top cover 102 is fixedly connected to the upper end of the cylinder body 101, and a bottom plate 103 is fixedly connected to the lower end of the cylinder body 101. A stirring mechanism 2 and a feeding mechanism 3 for quantitatively adding drugs are provided on the top cover 102. An air blowing mechanism 4 for introducing air into the dissolving cylinder 1 is provided on the bottom plate 103. A sealing mechanism 5 for sealing the dissolving cylinder 1 is provided below the bottom plate 103. A water pipe 6 for adding water into the dissolving cylinder 1 is provided on the side wall of the cylinder body 101, and an electrically controlled valve 7 is provided on the water pipe 6.

[0023] In this embodiment, the height of the upper surface of the base plate 103 gradually decreases from the edge to the center, so as to facilitate the discharge of the drug solution from the outlet 1031.

[0024] In this embodiment, the stirring mechanism 2 includes a drive motor 201 fixedly connected to the top cover 102. A bevel gear 202 is fixedly connected to the output shaft of the drive motor 201. A rotating shaft 203 is also rotatably connected to the top cover 102. A bevel gear 204 is fixedly connected to the upper end of the rotating shaft 203. The bevel gear 202 and the bevel gear 204 mesh. A plurality of horizontal stirring rods 205 are evenly fixedly connected to the rotating shaft 203.

[0025] In this embodiment, the feeding mechanism 3 includes a hopper 301 fixedly connected to the top cover 102. A hydraulic rod 302 is fixedly connected to the hopper 301. A connecting rod 303 is fixedly connected to the movable end of the hydraulic rod 302. Two stops 304 are fixedly connected in parallel on the connecting rod 303. The outer diameter of the stops 304 is equal to the inner diameter of the lower section of the hopper 301.

[0026] In this embodiment, the gap formed between the two baffles 304 and the lower end of the hopper 301 is fixed, so that the connecting rod 303 drives the baffles 304 to move down each time and send a fixed volume of medicine into the dissolving cylinder 1, thereby achieving the effect of equal amount feeding.

[0027] In this embodiment, the upper surface of the baffle 304 gradually rises from the edge to the center, making it easier for the drug on the lower baffle 304 to fall off and for the drug in the hopper to be squeezed out more easily when the upper baffle 304 moves upward.

[0028] In this embodiment, the air blowing mechanism 4 includes an annular tube 401 fixedly connected to the base plate 103. A plurality of radial tubes 402 are evenly fixedly connected to the inner side of the annular tube 401. A plurality of air outlets 403 are evenly opened on the annular tube 401 and the radial tubes 402. An air inlet pipe 404 is fixedly connected to the outer side of the annular tube 401. A one-way valve 405 is connected to the air inlet pipe 404. An air pump 406 is fixedly connected to the end of the air inlet pipe 404. A heating component 407 capable of heating air is provided at the air inlet of the air pump 406.

[0029] In this embodiment, the one-way valve 405 prevents water in the dissolving cylinder 1 from flowing back into the air pump 406 through the air inlet pipe 404.

[0030] In this embodiment, the heating assembly 407 includes a heating chamber 4071 fixedly connected to the air inlet of the air pump 406, and a plurality of resistance wires 4072 are uniformly fixedly connected in the heating chamber 4071.

[0031] In this embodiment, the sealing mechanism 5 includes two hydraulic rods 501 fixedly connected to the bottom surface of the base plate 103. A connecting plate 502 is fixedly connected to the movable end of the hydraulic rod 501. A sealing plug 503 is fixedly connected to the connecting plate 502. An outlet 1031 is provided at the center of the base plate 103. The sealing plug 503 abuts against the base plate 103 to seal the outlet 1031.

[0032] The working process of this drug dissolving device for wastewater treatment is as follows:

[0033] The electric valve 7 is opened, and the water in the water pipe 6 enters the dissolving cylinder 1 through the electric valve 7. After a period of time, the electric valve 7 is closed, so that there is a certain amount of water in the dissolving cylinder 1.

[0034] Start the drive motor 201. The drive motor 201 drives the bevel gear 202 connected to its output shaft to rotate. Since the bevel gear 204 meshes with the bevel gear 202, the rotating shaft 203 and the bevel gear 204 will be driven to rotate by the bevel gear 202. The rotating shaft 203 drives the several horizontal stirring rods 205 fixedly connected to it to rotate, stirring the water in the dissolving cylinder 1.

[0035] When the drive motor 201 is started, the air pump 406 is started at the same time, and all the resistance wires 4072 are energized. The air pump 406 draws in external air through the heating chamber 4071 and introduces this air into the air inlet pipe 404. This air enters the annular pipe 401 and the radial pipe 402 through the one-way valve 405, and is introduced into the water through the air outlet 403. The resistance wires 4072 will heat up after being energized, which will heat the air entering the air pump 406, so that the air introduced into the water has a certain amount of heat.

[0036] Then, the hydraulic rod 302 is extended, which drives the connecting rod 303 and the stop block 304 connected to the movable end of the hydraulic rod 302 to move downward. When the lower stop block 304 disengages from the lower end of the hopper 301, the medicine between the two stop blocks 304 will slide down from the stop block 304 and fall into the water. Then, the hydraulic rod 302 retracts and resets, so that the medicine in the hopper 301 can flow and fill the space between the two stop blocks 304.

[0037] Because of the rotation of the horizontal stirring rod 205, the water will also be driven to rotate, which can accelerate the dissolution of the drug in the water. The bubbles surging from bottom to top can further enhance the vertical flow of water and accelerate the dissolution of the drug. The heat attached to the air will be absorbed by the water, and hot water will rise and cold water will sink, further enhancing the flow of water. At the same time, the increase in water temperature will also accelerate the dissolution of the drug.

[0038] After dissolution is complete, turn off the drive motor 201 and air pump 406 to stop the power supply to the resistance wire 4072. Then, extend the hydraulic rod 501. The movable end of the hydraulic rod 501 drives the sealing plug 503 to move down through the connecting plate 502, so that the outlet 1031 opens and the dissolved drug is discharged.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
