An industrial wastewater treatment and reuse apparatus

Abstract

This invention provides an industrial wastewater treatment and reuse device, including a tank and a tank cover. A stirring paddle is concentrically rotatably mounted on the inner side of the tank. An inlet pipe, communicating with the inner side of the tank, is axially inserted into the tank cover. A first cylindrical body is positioned on the top of the tank cover corresponding to the inlet pipe. The top of the inlet pipe extends into and communicates with the inner side of the first cylindrical body. A first driving assembly drives the inlet pipe to reciprocate axially relative to the first cylindrical body. When the inlet pipe reciprocates axially relative to the first cylindrical body, a second driving assembly intermittently blocks the input end at the top of the inlet pipe. This invention utilizes only the rotation of the stirring paddle as a power source, enabling the inlet pipe to reciprocate axially relative to the first cylindrical body, intermittently and quantitatively delivering a preliminary mixture of industrial wastewater and chemical solution into the tank. This ensures a thorough neutralization reaction between the industrial wastewater and the chemical solution within the tank, improving the efficiency of industrial wastewater treatment and accelerating the recycling process of the treated water in subsequent filtration and recovery.

Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically to an industrial wastewater treatment and reuse device. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Industrial wastewater refers to wastewater, sewage, and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, finished products, and pollutants generated during production that are lost with the water. To meet environmental protection requirements, industrial wastewater needs to be treated using industrial wastewater treatment equipment before it is discharged.

[0004] Currently, common industrial wastewater treatment equipment on the market requires that the industrial wastewater be first transported to a reaction vessel, then the corresponding chemical solution be added to react with the wastewater to neutralize the harmful substances, and then the treated water be transported to subsequent filtration equipment for recycling.

[0005] However, during this process, the conveying pressure of industrial wastewater and / or chemical solutions is easily affected by external factors and fluctuates. When the conveying pressure suddenly increases, the flow rate of industrial wastewater and / or chemical solutions conveyed to the reaction vessel per unit time will suddenly increase. This leads to insufficient and incomplete neutralization reaction between industrial wastewater and chemical solutions, resulting in poor treatment effect and low efficiency of industrial wastewater. Summary of the Invention

[0006] The main objective of this invention is to provide an industrial wastewater treatment and reuse device.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: an industrial wastewater treatment and reuse device includes an upright tank and a tank cover disposed on the top of the tank, and a stirring paddle is concentrically rotatably disposed inside the tank.

[0008] At least one liquid inlet pipe that communicates with the inside of the tank is axially inserted into the tank cover;

[0009] A first cylinder is provided at the top of the tank cover at the position corresponding to the liquid inlet pipe; the top of the liquid inlet pipe extends into and connects to the inside of the first cylinder.

[0010] The first cylinder is respectively connected to a first liquid supply pipe for inputting industrial wastewater into it and a second liquid supply pipe for inputting pharmaceutical solution into it;

[0011] The stirring paddle is provided with a first driving component, and the first cylinder is provided with a second driving component.

[0012] When the stirring paddle rotates, the first driving component drives the inlet pipe to reciprocate axially relative to the first cylinder; when the inlet pipe reciprocates axially relative to the first cylinder, the second driving component intermittently blocks the input end at the top of the inlet pipe.

[0013] Furthermore, the first drive assembly includes a second cylinder sleeved on the outside of the stirring paddle. The inner wall of the second cylinder has an axially formed groove with a figure-eight structure and a closed loop. The outer wall of the stirring paddle is provided with a protrusion that slides and engages with the groove. A first connecting rod is radially fixed on the outer wall of the liquid inlet pipe, and one end of the first connecting rod is fixed on the outer wall of the second cylinder.

[0014] Furthermore, a drive motor is installed on the top of the tank lid, and the output shaft of the drive motor passes through the tank body and is fixedly connected to the top of the stirring paddle.

[0015] Furthermore, the second drive assembly includes a first valve block housed within the first cylinder, the first valve block being located at the top of the inlet pipe and moving synchronously with the inlet pipe;

[0016] The first cylinder has a flow channel cavity that connects the output end of the first liquid supply pipe and the output end of the second liquid supply pipe. The first cylinder is provided with a first valve groove that cooperates with the first valve block and connects to the bottom of the flow channel cavity.

[0017] Specifically, when the first valve block moves upward and disengages from the first valve slot, the inlet end of the liquid inlet pipe is connected to the flow channel cavity; when the first valve block moves downward and enters the first valve slot, the connection between the inlet end of the liquid inlet pipe and the flow channel cavity is blocked.

[0018] Furthermore, the top of the inlet pipe is fixed to the bottom of the first valve block; an inlet hole is radially opened on the outer wall of the inlet pipe near the top, and the inlet hole serves as the input end of the inlet pipe and connects to the inside of the pipe body.

[0019] When the first valve block moves upward and disengages from the first valve groove, the liquid inlet hole connects to the flow channel cavity;

[0020] When the first valve block moves down into the first valve slot, it blocks the connection between the liquid inlet and the flow channel cavity.

[0021] Furthermore, a flow stabilizing plate is fixed in the flow channel cavity above the first valve block, and the flow stabilizing plate has multiple flow stabilizing holes.

[0022] Furthermore, a second connecting rod coaxial with the inlet pipe is fixed to the top of the first valve block, and a second valve groove communicating with the top of the flow channel cavity is provided inside the first cylinder. A second valve block cooperating with the second valve groove is fixed to the second connecting rod, and the output end of the first liquid supply pipe and the output end of the second liquid supply pipe are both located above the second valve block.

[0023] A liquid storage space is formed between the top of the second valve block and the top wall of the second valve groove. A liquid guide pipe is provided on the first cylinder. The input end of the liquid guide pipe is connected to the liquid storage space, and the output end is connected to the flow channel cavity.

[0024] A first valve plate is provided at both the output end of the first liquid supply pipe and the output end of the second liquid supply pipe, and a second valve plate is provided at the output end of the liquid guide pipe. A transmission component is provided on the second valve block.

[0025] When the second valve block moves upward in the second valve groove, it drives the first valve plate to close and the second valve plate to open through the transmission assembly.

[0026] When the second valve block moves down in the second valve groove, it drives the first valve plate to open and the second valve plate to close through the transmission assembly.

[0027] Furthermore, the transmission assembly includes a transmission rod fixed to the top or bottom wall of the second valve block and parallel to the axial direction of the agitator. The end of the transmission rod away from the second valve block is provided with a U-shaped groove. A slider is provided in the groove. A rotating shaft parallel to the liquid inlet is horizontally inserted into the slider. A third connecting rod is radially fixed on the outer wall of the rotating shaft. The end of the third connecting rod away from the rotating shaft is vertically fixed to the surface of the first valve plate or the surface of the second valve plate.

[0028] Furthermore, the plates of the first valve plate and the second valve plate are hinged to the corresponding groove walls of the second valve groove.

[0029] Furthermore, a drain valve is installed at the bottom of the tank; a bracket is installed on the outside of the tank.

[0030] The beneficial effects of this invention are reflected in:

[0031] The industrial wastewater treatment and reuse equipment of the present invention uses only the rotation of the agitator as a power source, and in conjunction with the use of the drive component, the inlet pipe can move axially back and forth relative to the first cylinder to intermittently and quantitatively deliver the preliminary mixture formed by industrial wastewater and chemical solution into the tank, ensuring that the neutralization reaction between industrial wastewater and chemical solution in the tank is sufficient and thorough, improving the industrial wastewater treatment efficiency, and accelerating the recycling process of the treated water in subsequent filtration and recovery.

[0032] The industrial wastewater treatment and reuse equipment of the present invention, by setting a second valve block, valve plate, liquid guide pipe, etc., when the second valve block moves up and down synchronously with the first valve block through the second connecting rod, can intermittently and quantitatively deliver the preliminary mixed liquid into the flow channel cavity, avoiding the situation where the industrial wastewater and / or chemical solution in the first cylinder is delivered into the flow channel cavity in a short time due to the influence of a sudden increase in external delivery pressure, which would damage the internal structure of the first cylinder, and thus avoid the first cylinder from bursting and being damaged by high pressure.

[0046] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the invention, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0047] Please combine Figures 1 to 10 .

[0048] An industrial wastewater treatment and reuse device includes an upright tank 1 and a tank cover 2 on top of the tank 1. An agitator 3 is concentrically rotatably mounted inside the tank 1, and the agitator 3 has blades 4. A drain valve (not shown) is installed at the bottom of the tank 1.

[0049] At least one inlet pipe 5, communicating with the inside of the tank body 1, is axially inserted into the tank cover 2. A first cylindrical body 6 is provided at the top of the tank cover 2 corresponding to the position of the inlet pipe 5. The top of the inlet pipe 5 extends into and communicates with the inside of the first cylindrical body 6. A first supply pipe 8 for introducing industrial wastewater into the first cylindrical body 6 and a second supply pipe 9 for introducing chemical solution into the first cylindrical body 6 are respectively connected and provided. In this way, the industrial wastewater to be treated and the chemical solution and reagents for reacting with the industrial wastewater are transported into the tank body 1 through the inlet pipe 5.

[0050] The agitator 3 is equipped with a first drive assembly, and the first cylinder 6 is equipped with a second drive assembly.

[0051] When the agitator 3 rotates, the first drive assembly drives the inlet pipe 5 to reciprocate axially relative to the first cylinder 6. When the inlet pipe 5 reciprocates axially relative to the first cylinder 6, the second drive assembly intermittently blocks the input end at the top of the inlet pipe 5.

[0052] In a specific embodiment, the industrial wastewater to be treated and the chemical solution for reacting with the industrial wastewater are respectively supplied to the first cylinder 6 through the first liquid supply pipe 8 and the second liquid supply pipe 9. The mixed liquid is then input into the tank 1 through the liquid inlet pipe 5 and fully mixed and reacted under the stirring action of the stirring paddle 3 to complete the treatment of the industrial wastewater. Then the drain valve is opened to discharge the wastewater for subsequent recycling operations.

[0053] During this period, the rotation of the stirring paddle 3 can drive the liquid inlet pipe 5 to move axially back and forth relative to the first cylinder 6 through the first drive assembly. At this time, the second drive assembly can intermittently block the input end at the top of the liquid inlet pipe 5, so that the mixture in the first cylinder 6 is intermittently input into the tank 1 through the liquid inlet pipe 5, thereby realizing continuous intermittent feeding into the tank 1.

[0054] The advantage of this design is that it utilizes only the rotational stirring action of the agitator 3 within the tank 1 to achieve continuous intermittent delivery of the mixture of industrial wastewater and pharmaceutical solution into the tank 1, ensuring that the pharmaceutical solution in the tank 1 can fully react with the corresponding substances in the industrial wastewater, thereby improving the industrial wastewater recycling rate.

[0055] It should be noted that the industrial wastewater entering the first cylinder 6 through the first liquid supply pipe 8 has a predetermined pressure, and the pharmaceutical liquid entering the first cylinder 6 through the second liquid supply pipe 9 also has a predetermined pressure, so that the industrial wastewater and pharmaceutical liquid can be initially mixed to form a mixed liquid and then introduced into the tank 1 through the liquid inlet pipe 5.

[0056] In addition, both the tank cover 2 and the bottom of the first cylinder 6 have perforations (not shown) for the axial movement of the liquid inlet pipe 5, and a sealing ring (not shown) is provided between the liquid inlet pipe 5 and the perforation to ensure the sealing of the first cylinder 6 when the liquid inlet pipe 5 moves.

[0057] In one embodiment, the first drive assembly includes a second cylinder 10 sleeved on the outside of the stirring paddle 3. The inner wall of the second cylinder 10 has an axially formed groove 11 with a figure-eight structure and a closed loop. The outer wall of the stirring paddle 3 is provided with a protrusion 12 that slides and engages with the groove 11. A first connecting rod 13 is radially fixed on the outer wall of the liquid inlet pipe 5. One end of the first connecting rod 13 is fixed on the outer wall of the second cylinder 10.

[0058] Thus, the rotation of the stirring paddle 3 can be transmitted to the second cylinder 10 by the continuous friction and compression of the groove wall of the groove 11 with an axial figure-eight structure and a closed loop through the protrusion 12 on it. Under the limiting action of the liquid inlet pipe 5, the second cylinder 10 moves back and forth relative to the stirring paddle 3 in the axial direction. Then, through the first connecting rod 13, the liquid inlet pipe 5 is driven to move back and forth in the axial direction of the first cylinder 6.

[0059] Preferably, a drive motor 30 is installed on the top of the tank lid 2, and the output shaft of the drive motor 30 passes through the tank body 1 and is fixedly connected to the top of the stirring paddle 3. In this way, the stirring paddle 3 can be driven to rotate by the output shaft of the drive motor 30.

[0060] In one embodiment, the second drive assembly includes a first valve block 14 housed within the first cylinder 6, the first valve block 14 being located at the top of the inlet pipe 5 and moving synchronously with the inlet pipe 5.

[0061] The first cylinder 6 has a flow channel cavity 7 that connects the output end of the first liquid supply pipe 8 and the output end of the second liquid supply pipe 9. The first cylinder 6 has a first valve groove 15 that cooperates with the first valve block 14 and connects to the bottom of the flow channel cavity 7.

[0062] When the first valve block 14 moves upward and disengages from the first valve groove 15, the inlet end of the liquid inlet pipe 5 is connected to the flow channel cavity 7. When the first valve block 14 moves downward and enters the first valve groove 15, the connection between the inlet end of the liquid inlet pipe 5 and the flow channel cavity 7 is blocked.

[0063] Therefore, when the inlet pipe 5 moves the first valve block 14 upward and away from the first valve groove 15, the first valve groove 15 connects with the flow channel cavity 7, that is, the input end of the inlet pipe 5 connects with the flow channel cavity 7. At this time, the industrial wastewater and the chemical solution can initially mix to form a mixed liquid, which enters the flow channel cavity 7 and flows to the inlet pipe 5, and is then transported to the tank 1 through the inlet pipe 5 to participate in the wastewater treatment reaction. When the inlet pipe 5 moves the first valve block 14 downward into the first valve groove 15, the first valve block 14 will block the connection between the first valve groove 15 and the flow channel cavity 7, that is, block the connection between the input end of the inlet pipe 5 and the flow channel cavity 7. At this time, the mixed liquid formed by the industrial wastewater and the chemical solution cannot flow into the input end of the inlet pipe 5. As the inlet pipe 5 moves the first valve block 14 back and forth relative to the first valve groove 15, the inlet pipe 5 intermittently supplies material to the tank 1.

[0064] Preferably, the top of the inlet pipe 5 is fixed to the bottom of the first valve block 14 so that the inlet pipe 5 can directly drive the first valve block 14 to move. An inlet hole 16 is radially opened on the outer side wall of the inlet pipe 5 near the top, and the inlet hole 16 serves as the input end of the inlet pipe 5 and connects to the inside of the pipe body.

[0065] The advantage of this design is that when the first valve block 14 moves upward and disengages from the first valve groove 15, the inlet hole 16 connects to the flow channel cavity 7, allowing the mixed liquid to enter the first valve groove 15 through the flow channel cavity 7, and then flow into the inlet pipe 5 through the inlet hole 16, and then be transported to the tank 1 to participate in the wastewater treatment reaction through the inlet pipe 5. When the first valve block 14 moves downward and enters the first valve groove 15, it blocks the connection between the inlet hole 16 and the flow channel cavity 7, thus preventing the mixed liquid from entering the first valve groove 15 and achieving an indirect sealing effect on the inlet hole 16.

[0066] Furthermore, a second connecting rod 19 coaxial with the inlet pipe 5 is fixed to the top of the first valve block 14, and a second valve groove 21 communicating with the top of the flow channel cavity 7 is provided inside the first cylinder 6. A second valve block 20 cooperating with the second valve groove 21 is fixed to the second connecting rod 19. The output end of the first supply pipe 8 and the output end of the second supply pipe 9 are both located above the second valve block 20.

[0067] A liquid storage space (not shown) is formed between the top of the second valve block 20 and the top wall of the second valve groove 21. A liquid guide pipe 22 is provided on the first cylinder 6. The inlet end of the liquid guide pipe 22 is connected to the liquid storage space, and the outlet end is connected to the flow channel cavity 7.

[0068] A first valve plate 23 is provided at the output end of the first liquid supply pipe 8 and the output end of the second liquid supply pipe 9, a second valve plate 24 is provided at the output end of the liquid guide pipe 22, and a transmission component is provided on the second valve block 20.

[0069] In specific implementation, when the first valve block 14 drives the second valve block 20 to move upward in the second valve groove 21 through the second connecting rod 19, the second valve block 20 drives the first valve plate 23 to close and the second valve plate 24 to open through the transmission assembly, so that the second valve block 20 squeezes the mixture in the storage space and makes the mixture flow to the flow channel cavity 7 through the liquid guide pipe 22. At this time, the first valve block 14 is separated from the first valve groove 15. The mixture can enter the liquid inlet pipe 5 through the liquid inlet hole 16 after entering the first valve groove 15, so as to finally be transported to the tank 1 to participate in the water treatment stirring operation.

[0070] When the first valve block 14 drives the second valve block 20 to move downward in the second valve groove 21 via the second connecting rod 19, the second valve block 20 drives the first valve plate 23 to open and the second valve plate 24 to close via the transmission assembly, so that the liquid storage space expands to the initial state and forms a negative pressure, which can increase the rate at which the first liquid supply pipe 8 and the second liquid supply pipe 9 input industrial wastewater and pharmaceutical solution into the liquid storage space respectively, so as to quickly form a mixture in the liquid storage space, and thus prepare for the next upward compression and conveying by the second valve block 20.

[0071] It is worth mentioning that as the second valve block 20 moves up and down, it can intermittently and quantitatively deliver the mixed liquid into the flow channel cavity 7, avoiding the situation where the industrial wastewater and / or medicine in the first cylinder 6 is delivered into the flow channel cavity 7 in a short period of time due to the influence of changes in external delivery pressure, which could damage the internal structure of the first cylinder 6, thus preventing the first cylinder 6 from bursting and being damaged by high pressure.

[0072] In one embodiment, the number of transmission components may be three, with two located on the top wall of the second valve block 20 and the other on the bottom wall of the second valve block 20. The transmission component includes a transmission rod 25 fixed to the top or bottom wall of the second valve block 20 and parallel to the axial direction of the stirring paddle 3. The end of the transmission rod 25 away from the second valve block 20 is provided with a U-shaped groove 26. A slider 27 is provided in the groove 26. A rotating shaft 28 parallel to the liquid inlet hole 16 is horizontally inserted into the slider 27. A third connecting rod 29 is radially fixed to the outer wall of the rotating shaft 28. The end of the third connecting rod 29 away from the rotating shaft 28 is vertically fixed to the surface of the first valve plate 23 or the surface of the second valve plate 24.

[0073] Thus, the movement of the second valve block 20 can drive the slide groove 26 to move synchronously through the transmission rod 25, so that the corresponding valve plate can be opened or closed under the joint limiting traction of the third connecting rod 29, the rotating shaft 28, the slider 27 and the slide groove 26.

[0074] In one embodiment, the plates of the first valve plate 23 and the second valve plate 24 are hinged to the corresponding groove wall of the second valve groove 21.

[0075] In this way, the first valve plate 23 and the second valve plate 24 can be opened or closed under traction.

[0076] Furthermore, the first valve plate 23 has a sealing ring (not shown) on the side facing the first supply pipe 8 or the second supply pipe 9, ensuring a seal between the first valve plate 23 and the output end of the first supply pipe 8 or the second supply pipe 9 when the first valve plate 23 is closed. The second valve plate 24 has a sealing ring (not shown) on the side facing the output end of the guide pipe 22, ensuring a seal between the second valve plate 24 and the output end of the guide pipe 22 when the second valve plate 24 is closed.

[0077] In one embodiment, a flow stabilizing plate 17 is fixed in the flow channel cavity 7 above the first valve block 14, and the flow stabilizing plate 17 has a plurality of flow stabilizing holes 18. The longitudinal section of the flow stabilizing holes 18 is an inverted right trapezoidal structure.

[0078] In this way, the flow rate of the liquid flowing into the first valve groove 15 by the flow stabilizing hole 18 can protect the flow channel cavity 7 and prolong the reaction time between the liquids.

[0079] In one embodiment, a bracket 31 is installed on the outside of the tank 1 to facilitate the placement of the equipment in the wastewater treatment area.

[0080] 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, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0081] It should be noted that if the embodiments of the invention involve directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0082] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B. Additionally, if the embodiments of the invention involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the invention.
