Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment equipment, and in particular relates to a quick-dissolving mixing water bucket for adding medicines used in water plants. Background Art

[0002] With the development of economy and the progress of society, energy conservation has become inevitable and a social consensus. Various machines are increasingly developing in the direction of energy saving, easy use, space saving, safety and efficiency, and multi-functionality. In the water production industry, various agents need to be added, and the agents need to be dissolved into solutions, and then added with metering pumps. When using flocculants, the flocculants need to be prepared into a diluent of a certain concentration to facilitate the dispersion of the agents in water. The diluent will cause the efficacy of the agent to decrease due to the hydrolysis of the agent because the concentration is too low. In order to prevent the agent from being placed in a diluted state for too long, it is usually necessary to mix and dissolve the agent immediately, that is, to dissolve the agent while dissolving it and preparing it.

[0003] In order to ensure that the prepared medicine can be added to the dosing point in the shortest time, a smaller dissolution container is required, which makes the container for instant mixing and dissolution very small, and the time for mixing the medicine and water is very short, so the dissolution effect is very poor. Even if an agitator is installed for stirring, the water and medicine may not be fully dissolved and flow into the pipe behind. In actual work, the medicine itself usually contains insoluble substances. Under the action of the medicine, these insoluble substances are very easy to adhere to the pipe or the impeller of the pump, causing transportation problems or pipe blockage. In such a narrow mixer, it is impossible to install an agitator, feed port, water inlet, water outlet and other devices at the same time, and solve the above problems at the same time. Utility Model Content

[0004] The purpose of the utility model is to:

[0005] In order to solve the above problems, a rapid dissolving mixing water bucket for dosing in water plants is provided, which integrates filtering, spinning, collision, pressurization, precipitation and separation functions, so that the chemicals can be fully mixed, dissolved and hydrolyzed in a very short time, and quickly transported to the rear-end dosing point. It also has the functions of separating impurities, saving energy and being observable.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A quick-dissolving mixing water bucket for adding medicines for water plants, comprising a mixing water bucket, a pressurized reflux system and a water inlet control system;

[0008] The top of the mixing water bucket is connected to a top cover, and a medicine inlet is arranged on the top cover. A filter screen and a flocculation block are respectively installed in the mixing water bucket, a guide cone is installed at the bottom of the mixing water bucket, a sewage outlet is arranged at the bottom of the outer wall of the mixing water bucket, and a tangential water inlet and a tangential return water inlet are also respectively arranged on the outer wall of the mixing water bucket;

[0009] The pressurized reflux system comprises a pressurized dosing pump and a reflux pipe, wherein the water inlet of the pressurized dosing pump is connected to the medicine outlet, the water outlet of the pressurized dosing pump is connected to the reflux pipe, and the reflux pipe is connected to the tangential reflux water inlet;

[0010] The water inlet control system comprises a water inlet flow meter and a water inlet electric regulating valve which are communicated with the tangential water inlet.

[0011] Furthermore, a sedimentation mechanism and a slag collection net are arranged in the mixing water bucket, a sewage outlet, an overflow outlet and a medicine outlet are arranged on the outer wall of the sedimentation mechanism respectively, and the sewage outlet on the sedimentation mechanism is connected to a third flow control valve;

[0012] An inner water-turning baffle plate and an outer water-turning baffle plate are sequentially installed inside the sedimentation mechanism from the inside to the outside, and the inner water-turning baffle plate and the outer water-turning baffle plate are arranged in a staggered manner to form an S-shaped channel structure.

[0013] Furthermore, the drug outlet is connected to a pressurized dosing pump, one of the outlets of the pressurized dosing pump is connected to a fourth flow control valve, the fourth flow control valve is connected to a drug outlet flow meter, and the drug outlet flow meter is connected to a check valve;

[0014] Another outlet of the pressurized dosing pump is connected to a fifth flow control valve, which is communicated with the tangential return water inlet and is used to control the amount of return water to generate a vortex of appropriate intensity.

[0015] Furthermore, the tangential water inlet is connected to a first flow control valve, the first flow control valve is connected to a water inlet flow meter, the water inlet flow meter is connected to a water inlet electric regulating valve, and the water inlet electric regulating valve is connected to a Y-type filter.

[0016] Furthermore, the sewage outlet on the mixing water bucket is connected to a second flow control valve, a pressure transmitter is also connected between the mixing water bucket and the second flow control valve, and the overflow port is connected to an overflow detector.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0018] The utility model integrates all functions and structural components into one, saves space and cost, and has the characteristics of energy saving, filtration, and precipitation of insoluble matter. When working, medicine powder is put into the medicine inlet through the medicine inlet, and at the same time, the water from the tangential water inlet and the solvent dissolved by the reflux of the booster pump enter the tangential water inlet together, and the solvent passes through the tangential impact of the activation cone and the water inlet in the lower cylinder, and the water rushes straight along the inner wall to form self-rotation and allows the medicine powder and water to be fully mixed through the flocculation block. Under the premise of not applying additional mechanical power, pressurized self-rotation can be achieved to fully mix the medicine solution. Compared with the prior art, it plays the role of a stirrer and realizes an integrated mixing water bucket structure that can be observed, discharged, and overflowed. In long-term operation, it can effectively reduce costs and increase benefits for production enterprises.

[0019] The insoluble matter precipitation mechanism of the utility model is composed of a plurality of layers of cylindrical water turning baffles. Through the up and down water turning and volume changes, the flow rate is reduced to facilitate the precipitation of the precipitate. During the second water turning (lower layer water passing), the volume of the water passing precipitation area is increased to slow down the flow rate, slow down the impact on the precipitate, and enhance the precipitation effect, so that the insoluble precipitate is precipitated at the bottom, while the dissolved solution is discharged through the medicine outlet at the top. When the precipitate accumulates to a certain extent, it is discharged through the mud discharge valve, thereby effectively avoiding the problem of excessive precipitate and impurity content in the discharged medicine clogging the pipeline and affecting the booster pump.

[0024] A quick dissolving mixing water bucket for adding medicine for water plants, comprising a mixing water bucket 6, a pressurized reflux system and a water inlet control system;

[0025] The top of the mixing water bucket 6 is connected to a top cover, on which a medicine inlet 14 is provided, a filter screen 16 and a flocculation block 26 are respectively installed in the mixing water bucket 6, a guide cone 7 is installed at the bottom of the mixing water bucket 6, a sewage outlet 8 is provided at the bottom of the outer wall of the mixing water bucket 6, and a tangential water inlet 5 and a tangential return water inlet 25 are also respectively provided on the outer wall of the mixing water bucket 6;

[0026] The pressurized reflux system includes a pressurized dosing pump 21 and a reflux pipe, wherein the water inlet of the pressurized dosing pump 21 is connected to the medicine outlet 19, the water outlet of the pressurized dosing pump 21 is connected to the reflux pipe, and the reflux pipe is connected to the tangential reflux water inlet 25;

[0027] The water inlet control system includes a water inlet flow meter 3 and a water inlet electric regulating valve 2 which are connected to the tangential water inlet 5 .

[0028] A sedimentation mechanism and a slag collecting net 15 are arranged in the mixing water bucket 6. A sewage outlet 8, an overflow outlet 12 and a medicine outlet 19 are arranged on the outer wall of the sedimentation mechanism. The sewage outlet 8 on the sedimentation mechanism is connected to a third flow control valve 11.

[0029] An inner water-turning baffle 17 and an outer water-turning baffle 18 are sequentially installed inside the sedimentation mechanism from the inside to the outside. The inner water-turning baffle 17 and the outer water-turning baffle 18 are arranged in a staggered manner to form an S-shaped channel structure.

[0030] The medicine outlet 19 is connected to a pressurized dosing pump 21, one outlet of the pressurized dosing pump 21 is connected to a fourth flow control valve 20, the fourth flow control valve 20 is connected to a medicine outlet flow meter 22, and the medicine outlet flow meter 22 is connected to a check valve 23;

[0031] Another outlet of the pressurized dosing pump 21 is connected to a fifth flow control valve 24 , which is in communication with the tangential return water inlet 25 and is used to control the amount of return water to generate a vortex of appropriate intensity.

[0032] The tangential water inlet 5 is connected to a first flow control valve 4 , the first flow control valve 4 is connected to a water inlet flow meter 3 , the water inlet flow meter 3 is connected to a water inlet electric regulating valve 2 , and the water inlet electric regulating valve 2 is connected to a Y-type filter 1 .

[0033] The sewage outlet 8 on the mixing water bucket 6 is connected to a second flow control valve 10 , a pressure transmitter 9 is further connected between the mixing water bucket 6 and the second flow control valve 10 , and the overflow port 12 is connected to an overflow detector 13 .

[0034] Some components of the utility model implement the functions as follows:

[0035] Y-type filter 1: Filter incoming clean water.

[0036] Water inlet electric regulating valve 2: The water inlet amount of the proportional valve is adjusted by calculating the water level in the mixing water bucket 6 through the water inlet flow meter 3, the medicine outlet flow meter 22, and the pressure transmitter 9.

[0037] Inlet flow meter 3: collects clean water inlet flow data and transmits it back to the control end.

[0038] Tangential water inlet 5: The water inlet is tangent to the water inlet at the bottom of the mixing bucket (refer to the top view of the cross section), and the water rushes straight along the inner wall of the bucket, and forms a vortex through the cooperation of the guide cone 7 to be fully mixed.

[0039] The guide cone 7: First, it prevents the flow rate in the center of the vortex from being zero, which will cause the precipitation and accumulation of the water-powder mixture; second, water and flocculants are adhesive, and an insoluble film will be formed after the precipitation reaction on the surface, which will eventually cause the mixture to accumulate at the bottom and block the bottom; third, it enhances the vortex effect when assisting mixing.

[0040] Drainage outlet 8: Two drainage outlets 8 are provided to ensure complete drainage of sewage.

[0041] Pressure transmitter 9: detects the water level in the mixing bucket 6 to prevent overflow or spillage due to excessively high water level.

[0042] Overflow detector 13: detect overflow and return data to the control end to adjust water inlet or drug outlet.

[0043] Slag collecting net 15: The larger holes are about 20*20mm, which are used to filter ropes, woven bags, large particles of impurities, etc. The debris in the net can be removed and cleaned during operation.

[0044] Filter 16: Smaller holes, about 0.2-1 mm, intercept other impurities and large particles of undissolved flocculants in the mixing water bucket 6 to ensure that the medicine is free of impurities.

[0045] Water-turning baffle: It is composed of two groups of cylindrical baffles. By turning the water up and down, the water is fully mixed and precipitated. During the second water turning (water flowing through the lower layer), the water-flowing and sedimentation area is enlarged, the flow rate is slowed down, and the sedimentation effect is enhanced. It is used to separate fine and insoluble sediments to prevent the sediments from clogging the pipes and pumps.

[0046] Pressurized dosing pump 21: The agent is added to the dosing point by pressurizing the pump, and the reflux solution is refluxed into the instant mixing bucket with a certain flow rate (due to the limitation of solution concentration, the flow rate of tap water used for dissolution is not large, and the impact force of the reflux tap water on the rotation is insufficient), thereby increasing the dissolution effect of the agent.

[0047] Medicine flow meter 22: collects medicine flow data and transmits it back to the control end.

[0048] Pressure reducing valve: controls the pressure of the medicine outlet pipeline and controls the reflux of excess medicine liquid.

[0049] Flocculation block 26: Under the impetus of the water vortex, the drug impacts the block to achieve effective collision and cutting, so that large drug blocks are turned into smaller drug blocks, which is beneficial to the dissolution of the drug.

[0050] The utility model integrates all functions and structural components into one, saves space and cost, and has the characteristics of anti-corrosion filtration. When working, medicine powder is put into the medicine inlet 14, and water is taken in by the tangential water inlet 5 at the same time. Water passes through the activation cone and the tangential impact of the water inlet in the lower cylinder, and the water rushes straight along the inner wall to form self-rotation and allows the medicine powder and water to be fully mixed through the flocculation block 26. Under the premise of not applying additional mechanical power, pressurized self-rotation can be achieved to fully mix the medicine solution. Compared with the dosing mixing equipment in the prior art, it is more energy-saving, and at the same time realizes an integrated mixing water bucket 6 structure that can be observed, discharged, and overflowed, which can effectively reduce costs and increase benefits for production enterprises in long-term operation.

[0051] The sedimentation mechanism of the utility model comprises a water turning baffle composed of a cylindrical baffle, which can fully mix and precipitate water by turning water up and down, and enlarge the water flow sedimentation area during the second water turning (lower layer water flow), slow down the flow rate, enhance the sedimentation effect, and make part of the insoluble sediment settle below the mixer, and the dissolved medicine is discharged through the upper medicine outlet 19, which effectively avoids the problem of high sediment and impurity content in the discharged medicine.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
