Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology, and in particular relates to a conveying device for PAM dosing and dilution water. Background Technology

[0002] Phosphorus-containing wastewater is prevalent in industrial production and urban life. With increasing environmental awareness, the requirements for treating this wastewater are becoming more stringent, necessitating the addition of phosphorus removal agents. Furthermore, to facilitate the removal of sediment in the water, the dilution water is a crucial component in the design and application of PAM (polyacrylamide) dosing devices. Its main purpose is to ensure that PAM dissolves in the appropriate proportion, thereby achieving efficient use. The PAM dosing dilution water conveying device is an automatic dosing device used in water treatment processes, primarily in wastewater treatment, papermaking, and chemical industries. However, it still has the following drawbacks in practical use:

[0003] During production and operation, under the influence of adverse factors such as power outages and water outages, backflow of phosphorus removal agent frequently occurs in the phosphorus removal agent dosing room and PAM dosing room, which has a significant impact on PAM dosing: phosphorus removal agent flows into the PAM dosing tank, causing a large amount of flocculent material to be generated in the PAM dosing tank, which wraps around the agitator, blocks the PAM dosing pipeline, blocks the PAM dosing pump, and causes the PAM dosing pump to malfunction. These adverse effects will seriously affect the dosing of PAM and the operation process of the high-efficiency sedimentation tank.

[0004] During production and operation, when faced with different wastewater purification needs, the phosphorus removal agent and flocculant are usually diluted thoroughly and then poured into different locations of the wastewater treatment equipment. However, when the flocculant and phosphorus removal agent are introduced into the wastewater during operation, the delivery of the flocculant or phosphorus removal agent needs to be adjusted to meet different purification requirements. The adjustment is not convenient. Utility Model Content

[0005] The purpose of this invention is to provide a conveying device for PAM dosing dilution water. By setting up a conveying box, a stopper assembly, and a conveying assembly, it solves the problems that the dephosphorizing agent is prone to backflow and contamination of the PAM dosing tank during production and operation, and that it is not convenient to adjust the composition of the conveyed solution.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a conveying device for PAM dosing and dilution water, comprising a conveying box, a stopper assembly, and a conveying component. The conveying component is fixedly connected to one side of the conveying box. The conveying component includes a conveying pipe, a transfer pipe, and a second manual valve. Two conveying pipes are arranged parallel to each other, with their central axes at the same height. A transfer pipe is fixedly connected to the center of the periphery of both conveying pipes. A second manual valve is fixed to the center of the periphery of the transfer pipe. One end of each conveying pipe is fixedly connected to one side of the conveying box. A stopper assembly is fixed to the outer side of each conveying pipe on the inner wall of the conveying box. During operation, the solution entering the conveying box is conveyed. When the stopper assembly is in operation, it blocks the ends of each conveying pipe to prevent liquid backflow. When the conveying component is in operation, it conveys PAM and phosphorus removal agent solution into the conveying box.

[0008] Furthermore, a fixing hole is symmetrically opened on one side of the conveyor box with the vertical center line as the axis of symmetry, and an output hole is evenly opened on the bottom of the conveyor box. The top of the conveyor box is open, and when the conveyor box is working, it provides a fixing hole to fix the conveying pipe.

[0009] Furthermore, the plug assembly includes a fixing strip and a spring. The fixing strip is fixed to the inner wall of the conveying box, and a spring is fixed to the side of the fixing strip near the center of the conveying box. When the plug assembly is working, the fixing plate is fixed to it by the spring.

[0010] Furthermore, the plug assembly also includes a fixing plate and a rubber plug. The fixing plate is fixed to the side of the spring away from the center of the fixed box, and the rubber plug is fixed to the center of the side of the fixing plate away from the spring. When the plug assembly is working, the rubber plug is connected through the fixing plate.

[0011] Furthermore, the two conveying pipes are respectively fixed in the fixing hole, and the rubber plug is movably connected in the conveying pipe. The rubber plug is inserted into the conveying pipe to seal the end of the conveying pipe.

[0012] Furthermore, the conveying assembly also includes an electrically controlled valve and a manual valve. The conveying pipe between the transfer pipe and the conveying box is fixed with an electrically controlled valve, and the conveying pipe on the side of the transfer pipe away from the conveying box is fixed with a manual valve. When the conveying assembly is working, the conveying on and off of the conveying pipe is controlled by the electrically controlled valve.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of phosphorus removal agent easily flowing back and contaminating the PAM dosing tank during production by setting up a conveying box, a plug assembly, and a conveying assembly. PAM and phosphorus removal agent solution are conveyed to the conveying box through a conveying pipe. During the conveying process, a rubber plug inside the conveying pipe is pushed open, causing the rubber plug to be pushed against a fixing plate. The fixing plate then causes a spring to bend, allowing PAM and phosphorus removal agent solution to enter the conveying box. If there is a power outage or the pump conveying PAM or phosphorus removal agent solution unexpectedly stops, and there are signs of backflow in the conveying box, the spring and fixing plate are pushed, causing the rubber plug to be inserted into the corresponding conveying pipe, immediately sealing the pipe and effectively preventing phosphorus removal agent backflow.

[0015] This invention solves the problem of inconvenient adjustment of the liquid delivery composition during production by setting up a delivery component. When the delivery component is working, the on / off state is controlled by an electric control valve and a manual valve. When the electric control valve is damaged, the delivery pipe can still be controlled by the manual valve. When working, if the liquid needs to be input through one delivery pipe and delivered to the delivery box through two delivery pipes or another delivery pipe, open the manual valve corresponding to the input liquid, open the manual valve, close one of the electric control valves, or open both electric control valves and close the manual valve that is not inputting liquid. At this time, the PAM or dephosphorizing agent solution is delivered between the manual valve and the delivery box, and then delivered to the delivery box. Therefore, it is more convenient to adjust the liquid delivery composition during production. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-4 This utility model relates to a conveying device for PAM dosing and dilution water, comprising a conveying tank 1, a stopper assembly 2, and a conveying assembly 3. The conveying assembly 3 is fixedly connected to one side of the conveying tank 1. When the conveying tank 1 is working, it conveys PAM and phosphorus removal agent solution into the wastewater. The conveying assembly 3 then conveys the PAM and phosphorus removal agent solution back into the conveying tank 1. The conveying assembly 3 includes a conveying pipe 301, a transfer pipe 304, and a manual valve 305. The two conveying pipes 301 are arranged parallel to each other, and their central axes are at the same height. The transfer pipe 304 is fixedly connected to the center of the periphery of both conveying pipes 301, and the two conveying pipes 301 are interconnected through the transfer pipe 304. A manual valve 305 is fixedly connected to the center of the periphery of the transfer pipe 304. Valve 305 and transfer pipe 304 are manually controlled by valve 305 to connect and disconnect the two delivery pipes 301. The ends of the two delivery pipes 301 away from the delivery box 1 are respectively connected to the PAM and phosphorus removal agent solution delivery equipment for water treatment. One end of the delivery pipe 301 is fixed to one side of the delivery box 1. Each delivery pipe 301 on the inner wall of the delivery box 1 is fixed with a plug assembly 2. When the plug assembly 2 is working, it blocks the ends of the two delivery pipes 301 respectively, so as to prevent the PAM and phosphorus removal agent solution entering the delivery box 1 from backflowing. The part between the electric control valve 302 of the two delivery pipes 301 and the delivery box 1 is fixed to the side wall of the water tank. When working, the liquid level in the water tank is higher than the height of the delivery pipe 301.

[0026] Specifically, a fixing hole 102 is symmetrically opened on one side of the conveying box 1 with the vertical center line as the axis of symmetry. An output hole 101 is evenly opened on the bottom of the conveying box 1. The top of the conveying box 1 is open. When the conveying box 1 is working, the conveying pipe 301 is fixed through the fixing hole 102. The conveying box 1 leaks PAM and phosphorus removal agent solution into the treated water pool through the output hole 101 at its bottom.

[0027] Furthermore, the plug assembly 2 includes a fixing strip 201 and a spring 202. The fixing strip 201 is fixed on the inner wall of the conveying box 1, and the spring 202 is fixed on the side of the fixing strip 201 near the center of the conveying box 1. When the plug assembly 2 is working, the spring 202 is fixed by the fixing strip 201, and the fixing plate 203 is connected to it by the spring 202.

[0028] Furthermore, the plug assembly 2 also includes a fixing plate 203 and a rubber plug 204. The fixing plate 203 is fixed on the side of the spring 202 away from the center of the fixed box, and the rubber plug 204 is fixed in the center of the side of the fixing plate 203 away from the spring 202. When the plug assembly 2 is working, the rubber plug 204 is connected through the fixing plate 203, and the ends of the two delivery pipes 301 are blocked by the rubber plug 204.

[0029] Furthermore, two conveying pipes 301 are respectively fixed in the fixing hole 102, and the rubber plug 204 is movably connected in the conveying pipe 301. The conveying box 1 fixes the conveying pipe 301 through the fixing hole 102. The conveying pipe 301 is blocked by the rubber plug 204, so that PAM and dephosphorizing agent solution can only enter the conveying box 1 after pushing the rubber plug 204 open.

[0030] The operation process of this embodiment is as follows: During operation, PAM and dephosphorizing agent solution are transported to the conveying box 1 through the conveying pipe 301. When PAM and dephosphorizing agent solution are transported to the conveying box 1 through the conveying pipe 301, the rubber stopper 204 inside the conveying pipe 301 is pushed and then pushed open, so that the rubber stopper 204 is pushed to the fixing plate 203. The fixing plate 203 drives the spring 202 to bend, and then PAM and dephosphorizing agent solution enter the conveying box 1. When the power is cut off or the pump for transporting PAM or dephosphorizing agent solution stops unexpectedly, and there are signs of backflow of liquid in the conveying box 1, the spring 202 and the fixing plate 203 are pushed, so that the rubber stopper 204 is inserted into the corresponding conveying pipe 301, and the corresponding conveying pipe 301 is immediately closed. Specific Implementation Example 2

[0031] Please see Figure 1 , 25. Based on the specific embodiment one, the conveying assembly 3 further includes an electrically controlled valve 302 and a manual valve 303. Electrically controlled valves 302 are fixed around the periphery of the conveying pipe 301 between the transfer pipe 304 and the conveying box 1. Manual valves 303 are fixed around the periphery of the conveying pipe 301 on the side of the transfer pipe 304 away from the conveying box 1. When the conveying assembly 3 is working, the on / off state is controlled by the electrically controlled valve 302 and the manual valve 303 respectively. When the electrically controlled valve 302 is damaged, the manual valve 303 can also be used to control the conveying pipe 301. When the 01 conveying system is in operation, if the liquid needs to be input through one conveying pipe 301, or if the liquid needs to be input through two conveying pipes 301, or if the liquid needs to be input through another conveying pipe 301, open the corresponding manual valve 1 303, open the manual valve 2 305, close one of the electric control valves 302, or open both electric control valves 302, and close the manual valve 1 303 that does not input liquid. At this time, the PAM or dephosphorizing agent solution is conveyed between the manual valve 1 303 and the conveying box 1, and then conveyed to the conveying box 1.

[0032] The operation process of this embodiment is as follows: When the conveying component 3 is working, the on-off state is controlled by the solenoid valve 302 and the manual valve 303. When the solenoid valve 302 is damaged, the on-off state of the conveying pipe 301 can also be controlled by the manual valve 303. When working, if it is necessary to input through one conveying pipe 301, or to convey to the conveying box 1 through two conveying pipes 301 or another conveying pipe 301, the manual valve 303 corresponding to the input liquid is opened, the manual valve 305 is opened, and one of the solenoid valves 302 is closed, or both solenoid valves 302 are opened and the manual valve 303 that does not input liquid is closed. At this time, PAM or dephosphorizing agent solution is conveyed between the manual valve 303 and the conveying box 1, and then conveyed to the conveying box 1.
