Description

Technical Field

[0001] The invention relates to the technical field of drainage devices, and in particular to a water supply and drainage device used in municipal construction projects. Background Art

[0002] Construction engineering refers to production activities during the implementation phase of construction, and is the construction process of various buildings. Water supply and drainage refers to the abbreviation of water supply system and drainage system. Water supply and drainage system is a general term for facilities that provide water and wastewater for people's lives, production, municipal administration and fire protection. Since the water flowing through the construction site is mixed with construction materials (including cement, lime, construction dust, paint and other pollutants), the water quality is polluted and cannot be directly discharged into the municipal rainwater pipe network.

[0003] In the related technology, the invention patent with announcement number CN116446510B discloses a water supply and drainage device for energy-saving building construction, and the key points of its technical solution are: a suction component is installed on a treatment box, and the suction component and the treatment box are connected through a conduit; a driving component for driving the suction component to work, the driving component is installed in the treatment box; a medicine supply component for inputting medicine into the suction component; and a spoiler component located in the treatment box, the spoiler component is connected to the suction component, and the spoiler component is also connected to the driving component through a linkage component. This patent can achieve sufficient mixing of drainage and medicine through the coordinated arrangement of the suction component, the driving component and the spoiler component, thereby avoiding the problem that the existing water supply and drainage device for energy-saving building construction cannot purify drainage during drainage.

[0004] However, the water supply and drainage device disclosed in the above patent achieves the purpose of water purification by adding medicine into the suction component and mixing the medicine with the collected drainage (i.e. sewage) by the flow disturbance component. However, in actual application, the following problems are still encountered: Since the sewage to be treated is continuously introduced into the treatment box, and the stirring device is constantly stirring the sewage (to mix the sewage and the reagent), a lot of water vapor (or water mist) will be distributed in the space above the water surface in the treatment box. In order to facilitate the addition of reagents, the reagent outlet needs to be kept open. If these water mists pass through the reagent outlet and come into contact with the reagent, the reagent will clump after being damp, thereby blocking the reagent outlet.

[0005] In view of this, we propose a water supply and drainage device for municipal construction projects to improve the deficiencies in the prior art. Summary of the invention

[0006] The present invention aims at the technical problems existing in the prior art and provides a water supply and drainage device for municipal construction projects to solve the problem in the above-mentioned background technology that excessive amount of flocculant added causes the internal flocculant to be wrapped by the agglomerated external flocculants and thus cannot fully contact with the sewage.

[0007] In order to solve the above-mentioned problems, the technical solution of the present invention is as follows: a water supply and drainage device for municipal construction engineering, comprising a treatment mechanism, the treatment mechanism comprising a treatment box, a stirring mechanism is arranged at the axial position inside the treatment box, a plurality of drug storage mechanisms and a blocking mechanism are arranged in sequence from high to low inside the treatment box, each of the drug storage mechanisms is coaxially connected to the stirring mechanism, the edge of the blocking mechanism is fixedly connected to the inner side wall of the treatment box, the stirring mechanism penetrates the blocking mechanism, and the stirring mechanism is rotatably connected to the blocking mechanism; The treatment mechanism is used to filter and treat the construction sewage introduced therein, and the plurality of medicine storage mechanisms rotate synchronously with the stirring mechanism, and the medicine is sprinkled into the treatment box by the rotating centrifugal force of the stirring mechanism, and the plurality of medicine storage mechanisms can sprinkle the medicine to multiple points in the treatment box along the radial direction of the stirring mechanism, and the stirring mechanism is used to stir the sewage and the medicine inside the treatment box; The blocking mechanism is used to support a plurality of rotating medicine storage mechanisms, and the blocking mechanism can reduce the amount of water vapor entering the medicine storage mechanisms, and the blocking mechanism can move the rotating medicine storage mechanisms to promote the speed of the medicine storage mechanisms to spread the medicine.

[0008] Based on the above description, it can be seen that compared with the prior art, the beneficial effects of the present invention are: 1. The treatment mechanism is set up to filter and treat the construction sewage introduced therein, and multiple medicine storage mechanisms rotate synchronously with the stirring mechanism. The rotating centrifugal force of the stirring mechanism is used to sprinkle the medicine into the treatment box, and the multiple medicine storage mechanisms can spread the medicine to multiple points in the treatment box along the radial direction of the stirring mechanism. Compared with putting the medicine into the sewage at one time, this method of spreading the medicine at multiple points makes the sewage and the medicine contact more fully. The stirring mechanism is used to stir the sewage and the medicine inside the treatment box, thereby enhancing the purification effect of the sewage.

[0009] 2. A blocking mechanism is provided to support multiple medicine storage mechanisms in rotation. The blocking mechanism can reduce the amount of water vapor entering the medicine storage mechanism, thereby preventing the water vapor from contacting and agglomerating with the medicine at the ejection hole, causing the ejection hole to be blocked. The blocking mechanism can also move the rotating medicine storage mechanism to promote the speed at which the medicine storage mechanism spreads the medicine.

[0010] On the basis of the above technical solution, the present invention can also make the following improvements: As a further improvement of the technical solution, a mounting seat is installed on the top of the processing mechanism, and an interception plate for intercepting flocculants is provided at the bottom of the processing box.

[0011] As a further improvement of the technical solution, a plurality of water holes are provided on the intercepting plate, and the stirring mechanism passes through the intercepting plate.

[0012] The beneficial effect of adopting the above-mentioned improvement scheme is that after the reagent is sprinkled into the treatment box, it contacts with the sewage in the treatment box to obtain floccules, and the floccules are intercepted by the interception plate, while the sewage is discharged from the treatment box.

[0013] As a further improvement of the present technical solution, the stirring mechanism includes a main rod and a motor, the main rod is located inside the processing box, the motor is fixedly connected to the mounting seat, the main rod is coaxially connected to the output shaft of the motor, and multiple groups of stirring blades are distributed on the main rod from high to low, and each group of stirring blades is distributed in a circular array on the periphery of the main rod.

[0014] The beneficial effect of adopting the above-mentioned improvement scheme is that the motor drives the main rod to rotate, and the main rod drives the blades thereon to stir the sewage and the reagent in the treatment box so that the two are mixed evenly.

[0015] As a further improvement of the present technical solution, the medicine storage mechanism includes a medicine storage box, and the medicine storage box is fixedly connected to the main rod.

[0016] As a further improvement of the technical solution, a plurality of groups of ejection holes are provided at the bottom of the medicine storage box, each group of the ejection holes is distributed along the radial direction of the treatment box, and the connecting line of each group of the ejection holes is perpendicular to the straight line where the treatment box is located.

[0017] As a further improvement of the technical solution, the throwing hole is obliquely opened at the bottom of the medicine storage box, and the distance between the bottom of the throwing hole and the axis of the treatment box is greater than the distance between the top of the throwing hole and the axis of the treatment box.

[0018] The beneficial effect of adopting the above improved solution is that when the main rod rotates, it will rotate with the medicine storage box, and under the action of the centrifugal force of the medicine storage box, the flocculant stored in the medicine storage box is thrown out into the treatment box. And because each group of throwing holes is distributed at intervals and the distance from the axis of the treatment box gradually becomes farther, this allows the medicine to be sprinkled into the treatment box from multiple points instead of being added to one place at a time.

[0019] As a further improvement of the technical solution, the blocking mechanism includes a baffle plate whose periphery is fixedly connected to the inner wall of the processing box, and a plurality of material discharge troughs are staggeredly provided on the baffle plate.

[0020] As a further improvement of the technical solution, a toggle module is provided at the edge of the feed chute, and the toggle module includes a plurality of protrusions.

[0021] As a further improvement of the present technical solution, the baffle is made of a hydrophobic material.

[0022] The beneficial effect of adopting the above-mentioned improvement scheme is that when the medicine storage box is driven by the main rod to rotate, the rotating medicine storage box continuously slides across the surface of the baffle, and when the bottom of the medicine storage box passes through the protrusion, it will be pushed by the protrusion, thereby accelerating the discharge of the medicine in the medicine storage box, and because the discharge troughs are distributed at intervals and staggered, that is to say, the process of the medicine in the medicine storage box falling into the sewage is intermittent, that is, only when the throwing-out hole is located above the discharge trough, the medicine will pass through the discharge trough and fall into the sewage, and when the throwing-out hole is located at the part of the top of the baffle where the discharge trough is not opened, the throwing-out hole will be covered by the baffle to prevent the medicine in the throwing-out hole from contacting with the water mist (the baffle is made of hydrophobic material, and the amount of water adhered to its surface is very small), thereby avoiding the throwing-out hole from being blocked by the agglomerated flocculants.

DETAILED DESCRIPTION

[0025] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In order to prevent an excessive amount of reagent (such as flocculant) from being added at one time, so that the sewage does not have enough time to fully contact with the flocculant, the present application adopts a multi-point, intermittent spraying method for adding the reagent.

[0027] See also Figure 1-Figure 3 As shown, the purpose of this embodiment is to provide a water supply and drainage device for municipal construction engineering, including a processing mechanism 100, the processing mechanism 100 includes a processing box 110, a stirring mechanism 200 is arranged at the axial position inside the processing box 110, and a plurality of drug storage mechanisms 300 and a blocking mechanism 400 are arranged in sequence from high to low inside the processing box 110, each drug storage mechanism 300 is coaxially connected to the stirring mechanism 200, the edge of the blocking mechanism 400 is fixedly connected to the inner side wall of the processing box 110, the stirring mechanism 200 penetrates the blocking mechanism 400, and the stirring mechanism 200 is rotatably connected to the blocking mechanism 400; The treatment mechanism 100 is used to filter and treat the construction sewage introduced therein, and the plurality of medicine storage mechanisms 300 rotate synchronously with the stirring mechanism 200, and use the rotating centrifugal force of the stirring mechanism 200 to sprinkle the medicine into the treatment box 110, and the plurality of medicine storage mechanisms 300 can spread the medicine to multiple points in the treatment box 110 along the radial direction of the stirring mechanism 200, and the stirring mechanism 200 is used to stir the sewage and the medicine inside the treatment box 110; The blocking mechanism 400 is used to support multiple rotating medicine storage mechanisms 300. The blocking mechanism 400 can reduce the amount of water vapor entering the medicine storage mechanism 300, and the blocking mechanism 400 can move the rotating medicine storage mechanism 300 to increase the speed of the medicine storage mechanism 300 to spread the medicine.

[0028] Working principle: First, the municipal construction project sewage to be treated is introduced into the treatment box 110, and then the power supply of the stirring mechanism 200 is started. The stirring mechanism 200 drives the medicine storage mechanism 300 to rotate. The rotating medicine storage mechanism 300 is pushed by the top of the blocking mechanism 400, so that the sewage treatment agent is intermittently sprinkled into the treatment box 110. At the same time, the stirring mechanism 200 stirs the sewage to make it fully mixed with the agent. After the agent contacts the impurities in the sewage, it agglomerates into flocs. The flocs flow in the direction of the water flow. The flocs are intercepted by the interception plate 130, and the purified water flows out of the treatment box 110.

[0029] During the process of spreading the agent by the agent storage mechanism 300, the spreading points of the agent are distributed at intervals along the straight line where the radius of the treatment box 110 is located, thereby preventing the agent from being unable to fully contact with the sewage due to excessive addition of the agent at one time.

[0030] like Figure 4 As shown, a mounting seat 120 is installed on the top of the processing mechanism 100, and an interception plate 130 for intercepting flocculants is provided at the bottom of the processing box 110.

[0031] The improvement lies in that a plurality of water holes are provided on the intercepting plate 130 , and the stirring mechanism 200 passes through the intercepting plate 130 .

[0032] It should be noted that after the reagent is sprinkled into the treatment box 110 , it contacts with the sewage in the treatment box 110 to obtain flocs, and the flocs are intercepted by the interception plate 130 , while the sewage is discharged from the treatment box 110 .

[0033] The principle of sewage purification by flocculants is as follows: colloidal particles in sewage usually carry an electric charge, which keeps them in a stable dispersed state in water. The added flocculants are generally electrolytes, which will ionize ions in water. These ions can enter the diffusion layer of the colloidal particles, neutralize the charge on the surface of the colloidal particles, reduce the electromotive force of the colloidal particles, and thus compress the double layer. When the double layer is compressed to a certain extent, the electrostatic repulsion between the colloidal particles decreases, and the van der Waals attraction between the particles increases relatively, and the colloidal particles will approach each other and aggregate.

[0034] At the same time, flocculants are usually high molecular polymers, and their molecular chains contain many active groups. These active groups can be adsorbed on the surface of colloidal particles or suspended impurities in sewage. At the same time, the long chains of high molecular polymers can play a connecting role between multiple particles, connecting multiple particles together like a bridge to form larger flocs. As the flocs continue to grow, their sedimentation speed will also increase, making them easier to separate from sewage.

[0035] When the amount of flocculant added is large, the volume of the generated flocs will continue to increase. During the sedimentation process, it will intercept and sweep away the colloidal particles and suspended impurities in the water like a sieve, causing them to precipitate together with the flocs, thereby achieving the purpose of removing impurities.

[0036] exist Figure 5 In the figure, the stirring mechanism 200 includes a main rod 210 and a motor 220. The main rod 210 is located inside the processing box 110. The motor 220 is fixedly connected to the mounting base 120. The main rod 210 is coaxially connected to the output shaft of the motor 220. There are multiple groups of stirring blades 230 distributed from high to low on the main rod 210, and each group of stirring blades 230 is distributed in a circular array on the periphery of the main rod 210.

[0037] That is, after the power of the motor 220 is turned on, the motor 220 drives the main rod 210 to rotate, and the main rod 210 drives the stirring blades 230 thereon to stir the sewage and the reagent in the treatment box 110 so that the two are mixed evenly.

[0038] When the added agent is a flocculant, the flocculant is mixed with the drainage and then falls into the treatment box 110 to form flocculation precipitation. However, if the amount of flocculant is not well controlled and too much is added at one time, the flocculant will react with water quickly on the outer layer and agglomerate, while the inner flocculant is wrapped by the outer flocculant before it can contact with water, thereby failing to achieve a sufficient purification effect on the sewage.

[0039] Next, through Figure 6-Figure 8 The specific structure of the medicine storage mechanism 300 is disclosed. The medicine storage mechanism 300 includes a medicine storage box 310 , and the medicine storage box 310 is fixedly connected to the main rod 210 .

[0040] Moreover, the ejection hole 320 is obliquely opened at the bottom of the medicine storage box 310 , and the distance between the bottom of the ejection hole 320 and the axis of the treatment box 110 is greater than the distance between the top of the ejection hole 320 and the axis of the treatment box 110 .

[0041] It should be noted that when the main rod 210 rotates, it will rotate with the medicine storage box 310. Under the action of the centrifugal force of the medicine storage box 310, the flocculant stored in the medicine storage box 310 is thrown out into the processing box 110. Since each group of throwing holes 320 is distributed at intervals and the distance from the axis of the processing box 110 gradually becomes farther, the medicine can be sprinkled into the processing box 110 from multiple points instead of being added to one place at a time.

[0042] Since the sewage to be treated is continuously introduced into the treatment box 110 and the stirring blades 230 are constantly stirring the sewage, a lot of water vapor (or water mist) will be distributed in the upper part of the treatment box 110. If the water mist passes through the ejection hole 320 and contacts the medicine in the medicine storage box 310, the ejection hole 320 will be blocked. Therefore, a blocking mechanism 400 for moving the medicine storage box 310 is provided.

[0043] Based on the above description, Fig. 9 The preferred effect of the blocking mechanism 400 is described. The blocking mechanism 400 includes a baffle 410 whose periphery is fixedly connected to the inner wall of the processing box 110 , and a plurality of material discharge troughs 420 are staggeredly provided on the baffle 410 .

[0044] It should be noted that a toggle module 430 is disposed at the edge of the material discharge chute 420 , and the toggle module 430 includes a plurality of protrusions.

[0045] It should be disclosed that the baffle 410 is made of a hydrophobic material, such as polytetrafluoroethylene.

[0046] Therefore, when the medicine storage box 310 is driven by the main rod 210 to rotate, the rotating medicine storage box 310 continuously passes through the surface of the baffle 410. When the bottom of the medicine storage box 310 passes through the protrusion, it will be moved by the protrusion, thereby accelerating the discharge of the medicine in the medicine storage box 310. Since the discharge troughs 420 are distributed at intervals and staggered, that is to say, the process of the medicine in the medicine storage box 310 falling into the sewage is intermittent, that is, only when the throwing hole 320 is located above the discharge trough 420, the medicine will pass through the discharge trough 420 and fall into the sewage. When the throwing hole 320 is located at the part of the top of the baffle 410 where the discharge trough 420 is not opened, the throwing hole 320 will be covered by the baffle 410 to prevent the medicine in the throwing hole 320 from contacting with the water mist (the baffle 410 is made of hydrophobic material, and the amount of water adhered to its surface is very small), thereby avoiding the throwing hole 320 from being blocked by the agglomerated flocculants.

[0047] In summary, the working principle of the present invention is as follows: First, the municipal construction project sewage to be treated is introduced into the treatment box 110, and then the power of the motor 220 is turned on, the motor 220 drives the main rod 210 to rotate, and the main rod 210 drives the stirring blade 230 thereon to stir the sewage and the agent in the treatment box 110 so that the two are mixed evenly. After the agent is sprinkled into the treatment box 110, it contacts the sewage in the treatment box 110 to obtain floccules, which are intercepted by the interception plate 130, and the sewage is discharged from the treatment box 110.

[0048] When the main rod 210 rotates, it will rotate with the medicine storage box 310. Under the action of the centrifugal force of the medicine storage box 310, the flocculant stored in the medicine storage box 310 is thrown out into the processing box 110. Since each group of throwing holes 320 is distributed at intervals and the distance from the axis of the processing box 110 gradually becomes farther, the medicine can be sprinkled into the processing box 110 from multiple points instead of being added to one place at a time.

[0049] When the medicine storage box 310 is driven by the main rod 210 to rotate, the rotating medicine storage box 310 continuously slides across the surface of the baffle 410. When the bottom of the medicine storage box 310 passes through the protrusion, it will be moved by the protrusion, thereby accelerating the discharge of the medicine in the medicine storage box 310. Since the discharge troughs 420 are distributed at intervals and staggered, that is to say, the process of the medicine in the medicine storage box 310 falling into the sewage is intermittent, that is, only when the throwing hole 320 is located above the discharge trough 420, the medicine will pass through the discharge trough 420 and fall into the sewage. When the throwing hole 320 is located at the part of the top of the baffle 410 where the discharge trough 420 is not opened, the throwing hole 320 will be covered by the baffle 410 to prevent the medicine in the throwing hole 320 from contacting with the water mist, thereby avoiding the throwing hole 320 being blocked by the flocculants after agglomeration.

[0050] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
