Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly relates to a treatment and reuse device for industrial wastewater. Background Art

[0002] The statements herein only provide background art related to the present invention and do not necessarily constitute prior art.

[0003] Industrial wastewater refers to the wastewater, sewage, and liquid waste generated during industrial production, which contains industrial production raw materials, intermediate products, products, and pollutants generated during the production process that are lost with water; to meet environmental protection requirements, industrial wastewater treatment equipment is required before industrial wastewater is discharged.

[0004] Common industrial wastewater treatment equipment on the market currently, when filtering industrial wastewater, needs to first transport the industrial wastewater to a reaction vessel, then add corresponding chemical liquid medicines to react with the wastewater to neutralize harmful substances therein, and then transport the treated water to subsequent filtering equipment for recycling.

[0005] However, in this process, since the transport pressure when transporting industrial wastewater and / or chemical liquid medicines is easily affected by external factors and fluctuates, when the transport pressure suddenly increases, the flow rate of industrial wastewater and / or chemical liquid medicines transported to the reaction vessel per unit time will suddenly increase, which results in an insufficient and incomplete neutralization reaction between the industrial wastewater and the chemical liquid medicines, and there are problems of poor treatment effect and low efficiency for industrial wastewater treatment. Summary of the Invention

[0006] The main object of the present invention is to provide a treatment and reuse device for industrial wastewater.

[0007] To achieve the above object, the technical solution of the present invention is implemented as follows: A treatment and reuse device for industrial wastewater includes a vertically arranged tank body and a tank cover arranged on the top of the tank body, and a stirring paddle is rotatably arranged concentrically inside the tank body;

[0008] At least one liquid inlet pipe communicating with the inside of the tank body is axially inserted on the tank cover;

[0009] A first cylinder body is arranged at the position corresponding to the liquid inlet pipe on the top of the tank cover; the top of the liquid inlet pipe extends into and communicates with the inside of the first cylinder body;

[0010] A first liquid supply pipe for inputting industrial wastewater into it and a second liquid supply pipe for inputting liquid medicine into it are respectively communicated and arranged on the first cylinder body;

[0011] A first driving component is arranged on the stirring paddle, and a second driving component is arranged inside the first cylinder body;

[0012] Wherein, when the stirring paddle rotates, the first driving assembly is used to drive the liquid inlet pipe to axially reciprocate relative to the first cylinder; when the liquid inlet pipe axially reciprocates relative to the first cylinder, the second driving assembly is used to intermittently block the input end at the top of the liquid inlet pipe.

[0013] Furthermore, the first driving assembly includes a second cylinder sleeved outside the stirring paddle. An axially arranged groove in an eight-shaped structure and in a closed loop is formed on the inner side wall of the second cylinder. A convex block is arranged on the outer wall of the stirring paddle and is slidably clamped and matched with the groove. A first connecting rod is radially fixed on the outer side wall of the liquid inlet pipe, and one end of the first connecting rod is fixed on the outer side wall of the second cylinder.

[0014] Furthermore, a driving motor is installed on the top of the tank cover. The output shaft of the driving motor penetrates into the tank body and is fixedly connected to the top end of the stirring paddle.

[0015] Further, the second driving assembly includes a first valve block housed in the first cylinder. The first valve block is located at the top of the liquid inlet pipe and moves synchronously with the liquid inlet pipe.

[0016] A flow channel cavity communicating with the output end of the first liquid supply pipe and the output end of the second liquid supply pipe is formed in the first cylinder. A first valve groove communicating with the bottom of the flow channel cavity and matching with the first valve block is formed in the first cylinder.

[0017] Wherein, when the first valve block moves upward and disengages from the first valve groove, the input end of the liquid inlet pipe is communicated with the flow channel cavity; when the first valve block moves downward into the first valve groove, the communication state between the input end of the liquid inlet pipe and the flow channel cavity is blocked.

[0018] Furthermore, the top of the liquid inlet pipe is fixed to the bottom of the first valve block; a liquid inlet hole is radially formed on the outer side wall of the liquid inlet pipe near the top end. The liquid inlet hole serves as the input end of the liquid inlet pipe and is communicated with the inside of the pipe body of the liquid inlet pipe.

[0019] When the first valve block moves upward and disengages from the first valve groove, the liquid inlet hole is communicated with the flow channel cavity.

[0020] When the first valve block moves downward into the first valve groove, the communication state between the liquid inlet hole and the flow channel cavity is blocked.

[0021] Furthermore, a flow stabilizing plate located above the first valve block is fixed in the flow channel cavity, and the flow stabilizing plate is provided with a plurality of flow stabilizing holes.

[0022] Furthermore, a second connecting rod coaxial with the liquid inlet pipe is fixed to the top of the first valve block. A second valve groove communicating with the top of the flow channel cavity is formed inside the first cylinder. The second connecting rod is fixed with a second valve block matching with the second valve groove. The output ends of the first liquid supply pipe and 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 arranged on the first cylinder body. The input end of the liquid guide pipe is communicated with the liquid storage space, and the output end is communicated with the flow channel cavity.

[0024] First valve plates are arranged at the output ends of the first liquid supply pipe and the second liquid supply pipe respectively. A second valve plate is arranged at the output end of the liquid guide pipe. A transmission assembly is arranged on the second valve block.

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

[0026] When the second valve block moves downward in the second valve groove, the first valve plate is driven to open and the second valve plate is driven to close through the transmission assembly.

[0027] Furthermore, the transmission assembly includes a transmission rod fixed on the top wall or the bottom wall of the second valve block and parallel to the axial direction of the stirring paddle. A return-shaped sliding groove is arranged at the end of the transmission rod far away from the second valve block. A sliding block is arranged in the sliding groove. A rotating shaft parallel to the liquid inlet hole is horizontally and rotatably inserted on the sliding block. A third connecting rod is radially fixed on the outer wall of the rotating shaft. The end of the third connecting rod far away from the rotating shaft is vertically fixed on the plate surface of the first valve plate or the plate surface of the second valve plate.

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

[0029] Further, a liquid discharge valve is installed at the bottom of the tank body. A bracket is installed outside the tank body.

[0030] The beneficial effects of the present invention are as follows:

[0031] For the industrial wastewater treatment and reuse equipment of the present invention, only by using the rotation of the stirring paddle as the power source and cooperating with the use of the driving assembly, the liquid inlet pipe can move axially back and forth relative to the first cylinder body to intermittently and quantitatively transport the preliminary mixed liquid formed by industrial wastewater and liquid medicine into the tank body, ensuring that the neutralization reaction between the industrial wastewater and the chemical liquid medicine in the tank is sufficient and thorough, improving the industrial wastewater treatment efficiency, and accelerating the recycling process of the treated water in the subsequent filtration and recovery.

[0032] For the industrial wastewater treatment and reuse equipment of the present invention, by setting the second valve block, valve plates, liquid guide pipes, etc., when the second valve block moves up and down synchronously with the first valve block through the second connecting rod, the preliminary mixed liquid can be intermittently and quantitatively transported into the flow channel cavity, avoiding the situation that due to the sudden increase in the external conveying pressure, the industrial wastewater and / or liquid medicine in the first cylinder body are conveyed into the flow channel cavity in a large flow rate for a short time and damaging the internal structure of the first cylinder body, so as to avoid the first cylinder body being burst and damaged by high pressure.

[0046] The following will further describe the present invention in detail with reference to the drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all of the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the invention.

[0047] Please refer to Figures 1 to 10 。

[0048] A treatment and reuse device for industrial wastewater includes a vertically arranged tank body 1 and a tank cover 2 arranged on the top of the tank body 1. A stirring paddle 3 is rotatably arranged concentrically inside the tank body 1, and the stirring paddle 3 is provided with blades 4. A drain valve (not shown in the figure) is installed at the bottom of the tank body 1.

[0049] At least one liquid inlet pipe 5 communicating with the inside of the tank body 1 is axially inserted on the tank cover 2, and a first cylinder 6 is arranged at the position corresponding to the liquid inlet pipe 5 on the top of the tank cover 2. The top of the liquid inlet pipe 5 extends into and communicates with the inside of the first cylinder 6. A first liquid supply pipe 8 for inputting industrial wastewater into it and a second liquid supply pipe 9 for inputting liquid medicine into it are respectively communicated with the first cylinder 6. In this way, the industrial wastewater to be treated and the liquid medicine and medicament for reacting with the industrial wastewater treatment are transported into the tank body 1 through the liquid inlet pipe 5.

[0050] A first driving assembly is arranged on the stirring paddle 3, and a second driving assembly is arranged inside the first cylinder 6.

[0051] When the stirring paddle 3 rotates, the first driving assembly is used to drive the liquid inlet pipe 5 to axially reciprocate relative to the first cylinder 6. When the liquid inlet pipe 5 axially reciprocates relative to the first cylinder 6, the second driving assembly is used to intermittently block the input end at the top of the liquid inlet pipe 5.

[0052] In a specific embodiment, industrial wastewater to be treated and a liquid medicine for treating and reacting with the industrial wastewater are respectively conveyed into the first cylinder body 6 through the first liquid supply pipe 8 and the second liquid supply pipe 9, so that the mixed liquid is input into the tank body 1 through the liquid inlet pipe 5, and is fully mixed and reacted under the stirring action of the stirring paddle 3 to complete the treatment of the industrial wastewater, and then the drain valve is opened to discharge the treated wastewater, so as to carry out subsequent recovery operations.

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

[0054] The advantage of such a design is that only by using the rotation and stirring action of the stirring paddle 3 in the tank body 1, continuous intermittent feeding of the mixed liquid of industrial wastewater and liquid medicine into the tank body 1 is realized, ensuring that the liquid medicine in the tank body 1 can react fully with the corresponding substances in the industrial wastewater and improving the recovery rate of industrial wastewater.

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

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

[0057] In one embodiment, the first driving assembly includes a second cylinder body 10 sleeved outside the stirring paddle 3. An axially arranged groove 11 in a figure-eight shape and a closed loop is formed on the inner side wall of the second cylinder body 10. A convex block 12 is arranged on the outer wall of the stirring paddle 3 and is slidably clamped and matched with the groove 11. A first connecting rod 13 is radially fixed on the outer side wall of the liquid inlet pipe 5, and one end of the first connecting rod 13 is fixed on the outer side wall of the second cylinder body 10.

[0058] In this way, the rotation of the stirring paddle 3 can drive the second cylinder body 10 by continuously rubbing and pressing the groove wall of the axially figure-eight-shaped and closed-loop groove 11 through the convex block 12 thereon, so that the second cylinder body 10 axially reciprocates relative to the stirring paddle 3 under the limiting action of the liquid inlet pipe 5, and then drives the liquid inlet pipe 5 through the first connecting rod 13, so that the liquid inlet pipe 5 axially reciprocates in the first cylinder body 6.

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

[0060] In one embodiment, the second driving assembly includes a first valve block 14 received in the first cylinder 6. The first valve block 14 is located at the top of the liquid inlet pipe 5 and moves synchronously with the liquid inlet pipe 5.

[0061] There is a flow channel cavity 7 in the first cylinder 6 that connects the output end of the first liquid supply pipe 8 and the output end of the second liquid supply pipe 9. A first valve groove 15 that cooperates with the first valve block 14 and communicates with the bottom of the flow channel cavity 7 is opened in the first cylinder 6.

[0062] When the first valve block 14 moves upward and disengages from the first valve groove 15, the input end of the liquid inlet pipe 5 is communicated with the flow channel cavity 7. When the first valve block 14 moves downward into the first valve groove 15, the communication state between the input end of the liquid inlet pipe 5 and the flow channel cavity 7 is blocked.

[0063] Thus, when the liquid inlet pipe 5 drives the first valve block 14 to move upward and disengage from the first valve groove 15, the first valve groove 15 is communicated with the flow channel cavity 7, that is, the input end of the liquid inlet pipe 5 is communicated with the flow channel cavity 7. At this time, industrial wastewater and liquid medicine can be preliminarily mixed to form a mixed liquid that enters the flow channel cavity 7 and flows to the liquid inlet pipe 5, and then is transported to the tank body 1 through the liquid inlet pipe 5 to participate in the wastewater treatment reaction. When the liquid inlet pipe 5 drives the first valve block 14 to move downward into the first valve groove 15, the first valve block 14 blocks the communication state between the first valve groove 15 and the flow channel cavity 7, that is, blocks the communication state between the input end of the liquid inlet pipe 5 and the flow channel cavity 7. At this time, the mixed liquid formed by industrial wastewater and liquid medicine cannot flow into the input end of the liquid inlet pipe 5. As the liquid inlet pipe 5 drives the first valve block 14 to reciprocate relative to the first valve groove 15, intermittent feeding of the liquid inlet pipe 5 into the tank body 1 is realized.

[0064] Preferably, the top of the liquid inlet pipe 5 is fixed to the bottom of the first valve block 14 so that the liquid 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 liquid inlet pipe 5 near the top end. The inlet hole 16 serves as the input end of the liquid inlet pipe 5 and communicates with the inside of the pipe body of the liquid inlet pipe 5.

[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 is communicated with the flow channel cavity 7, enabling the mixed liquid to enter the first valve groove 15 through the flow channel cavity 7, and then flow into the liquid inlet pipe 5 through the inlet hole 16, and then be transported to the tank body 1 through the liquid inlet pipe 5 to participate in the wastewater treatment reaction. When the first valve block 14 moves downward into the first valve groove 15, the communication state between the inlet hole 16 and the flow channel cavity 7 is blocked, and the mixed liquid cannot enter the first valve groove 15 to achieve the indirect plugging effect on the inlet hole 16.

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

[0067] A liquid storage space (not labeled) 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 body 6. The input end of the liquid guide pipe 22 communicates with the liquid storage space, and the output end communicates with the flow channel cavity 7.

[0068] First valve plates 23 are provided at the output ends of the first liquid supply pipe 8 and 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 assembly is provided on the second valve block 20.

[0069] In a 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 mixed liquid in the liquid storage space, and the mixed liquid flows through the liquid guide pipe 22 to the flow channel cavity 7. At this time, the first valve block 14 is separated from the first valve groove 15, and the mixed liquid can enter the liquid inlet pipe 5 through the liquid inlet hole 16 after entering the first valve groove 15, so as to be finally transported to the tank body 1 to participate in the stirring operation of water treatment.

[0070] When the first valve block 14 drives the second valve block 20 to move downward in the second valve groove 21 through 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 through the transmission assembly, so that the liquid storage space expands to the initial state and forms a negative pressure, which can improve the rate of the first liquid supply pipe 8 and the second liquid supply pipe 9 to respectively input industrial waste water and liquid medicine into the liquid storage space, so as to quickly form a mixed liquid in the liquid storage space, and further prepare for the next extrusion and transportation by the upward movement of the second valve block 20.

[0071] It is worth mentioning that with the reciprocating up and down movement of the second valve block 20, the mixed liquid can be intermittently and quantitatively transported into the flow channel cavity 7, avoiding the situation that the industrial waste water and / or liquid medicine in the first cylinder body 6 are transported into the flow channel cavity 7 in a large flow rate in a short time due to the influence of external transportation pressure changes, which may damage the internal structure of the first cylinder body 6, so as to avoid the first cylinder body 6 being damaged by high pressure and bursting.

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

[0073] In this way, the movement of the second valve block 20 can drive the chute 26 to move synchronously through the transmission rod 25, so that the corresponding valve plate is opened or closed under the combined limit traction of the third connecting rod 29, the rotating shaft 28, the slider 27 and the chute 26.

[0074] In one embodiment, the plate bodies of the first valve plate 23 and the second valve plate 24 are hinged to the corresponding groove walls 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 the traction effect.

[0076] In addition, one side of the first valve plate 23 facing the first liquid supply pipe 8 or the second liquid supply pipe 9 has a sealing ring (not shown in the figure), so that when the first valve plate 23 is closed, the sealing performance between the first valve plate 23 and the output end of the first liquid supply pipe 8 or the second liquid supply pipe 9 is ensured. One side of the second valve plate 24 facing the output end of the liquid guide pipe 22 has a sealing ring (not shown in the figure), so that when the second valve plate 24 is closed, the sealing performance between the second valve plate 24 and the output end of the liquid guide pipe 22 is ensured.

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

[0078] In this way, by buffering the liquid flow rate of the mixed liquid flowing into the first valve groove 15 through the flow stabilizing holes 18, the flow channel cavity 7 can be protected, and the reaction time between the mixed liquids can be extended.

[0079] In one embodiment, a bracket 31 is installed outside the tank body 1, which is convenient for placing this equipment in the wastewater treatment area.

[0080] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.

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

[0082] In addition, the meaning of "and / or" appearing throughout the text includes three parallel scenarios. Taking "A and / or B" as an example, it includes scenario A, or scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, if there are descriptions such as "first" and "second" in the embodiments of the invention, the descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, "a plurality of" means more than two. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the invention.
