Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling, and specifically relates to a sewage treatment tank sampling device. Background Technique

[0002] A sewage treatment tank is a facility used to treat and purify sewage. Sewage treatment tanks usually include different treatment areas, such as a sedimentation area and a treatment area. The sedimentation area is mainly used to remove suspended particles in the wastewater, while the treatment area converts organic substances in the wastewater into harmless substances through the action of microorganisms. These tanks can treat different types of sewage, including domestic sewage, industrial sewage, agricultural sewage, and medical sewage, etc. Sewage treatment tanks play an important role in environmental protection and resource recovery. The sewage in the sewage treatment tank needs to meet the standards before it can be discharged or recycled, so a sampling device is required to sample the sewage.

[0003] Sampling devices generally perform single sampling, and only one sewage sample can be taken at a time. When the demand for samples is large, it requires staff to sample repeatedly, which is very troublesome and has low efficiency. Therefore, it is urgently needed to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sewage treatment tank sampling device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A sewage treatment tank sampling device includes a device frame, an air pump, a sampling tray, a sampling bottle, and an air suction branch pipe. The air pump is installed on one side of the top of the device frame, and an air suction main pipe is installed at the input end of the air pump. And one end of the air suction main pipe is installed with a swivel joint. The air suction branch pipes are all arranged on one side of the swivel joint. A controller is installed on the top of the air pump. On the other side of the top of the device frame, a lifting frame is fixed. And a vertical rod is arranged on one side of the lifting frame. The sampling tray is fixed at the bottom of the vertical rod, and equidistant round holes are arranged inside the sampling tray. The sampling bottle is arranged inside the round hole, and the top of the sampling bottle extends to the top of the sampling tray and is installed with a sealing cover. And an exhaust port is arranged at the center position of the top of the sealing cover.

[0006] Preferably, a positioning disk is fixed on the outer wall of the bottom of the vertical rod to facilitate the limitation of the air suction branch pipe.

[0007] Preferably, a scale is installed on the outer wall of the lifting frame to facilitate the measurement of the sampling depth.

[0008] Preferably, a screw rod is installed inside the lifting frame through bearings, and a guide rod is fixed inside the lifting frame on one side of the screw rod. A cross arm is sleeved on the outer walls of the screw rod and the guide rod. The cross arm is threadedly connected to the screw rod and slidably connected to the guide rod. One end of the cross arm extends to one side of the lifting frame and is welded to the vertical rod, facilitating driving the cross arm to move up and down.

[0009] Preferably, a rotary driving member is installed at the top end of the lifting frame, and the output end of the rotary driving member extends into the lifting frame and is fixedly connected to the screw rod for driving the screw rod.

[0010] Preferably, a one-way valve is installed at the bottom end of the sampling bottle, allowing sewage to enter the sampling bottle but not to discharge from the sampling bottle.

[0011] Preferably, a solenoid valve is installed at the connection between the suction branch pipe and the adapter, facilitating controlling the connection state of the suction branch pipe.

[0012] Preferably, one end of the suction branch pipe penetrates the positioning disk and is connected to the exhaust port, facilitating pumping out the air inside the sampling bottle, generating negative pressure suction in the sampling bottle, and sucking in the sewage.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: This sewage treatment tank sampling device can not only extract multiple groups of samples at one time, with high sampling efficiency, facilitating sampling of sewage at different depths, but also does not cause pollution to the suction branch pipe and can be recycled;

[0014] (1) By providing a sampling disk, round holes, sampling bottles, sealing caps, exhaust ports, one-way valves, suction main pipes, adapters, suction branch pipes, and solenoid valves, the staff sequentially place the sampling bottles in the round holes inside the sampling disk, connect the bottom end of the suction branch pipe to the lifting frame, place the sampling disk into the sewage treatment tank, and immerse the sampling bottles in the sewage. Since there are four groups of suction branch pipes corresponding to the sampling bottles one by one, first open the solenoid valve at one end of one of the suction branch pipes, start the air pump to extract the air inside the corresponding sampling bottle through the suction main pipe and the suction branch pipe, so that the sewage at this depth is pumped into the sampling bottle. The setting of the one-way valve allows sewage to enter the sampling bottle but not to discharge from the sampling bottle. After a certain amount of sewage is pumped into the sampling bottle, close the corresponding solenoid valve, then lower the sampling bottle to different depths, and in the above manner, open the remaining solenoid valves one by one and repeat the above actions to extract four groups of samples at one time, with high sampling efficiency, and automatic sampling, convenient operation, reducing the labor burden of the staff;

[0015] (2) By providing a lifting frame, a scale, a screw, a guide rod, a rotary drive member, a cross arm, and a vertical rod, the rotary drive member drives the screw to rotate, so that the cross arm moves down along the screw and the guide rod, and the cross arm drives the sampling plate to move down through the vertical rod, so that the sampling bottle can be lowered to different depths. By observing the cross arm and comparing it with the scale, the depth of the sampling bottle can be controlled. This design makes the sampling depth controllable and ensures the reliability of the sample, thereby facilitating the sampling of sewage at different depths;

[0016] (3) After the sampling is completed, the exhaust port and the suction branch are separated, and the sampling bottle is taken out from the round hole. Since the sewage is not poured into the suction branch during sampling, it will not cause pollution to the suction branch. When sampling subsequently, a new sampling bottle can be replaced and connected to the suction branch, so that the device can be recycled. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] A scale 7 is installed on the outer wall of the lifting frame 6, which is convenient for measuring the sampling depth;

[0028] A screw rod 19 is installed inside the lifting frame 6 through a bearing. And a guide rod 20 is fixed inside the lifting frame 6 on one side of the screw rod 19. And a cross arm 4 is sleeved on the outer walls of the screw rod 19 and the guide rod 20. The cross arm 4 is threadedly connected with the screw rod 19, and the cross arm 4 is slidably connected with the guide rod 20. One end of the cross arm 4 extends to one side of the lifting frame 6 and is welded to the vertical rod 5, which is convenient for driving the cross arm 4 to move up and down;

[0029] A rotary drive member 18 is installed on the top of the lifting frame 6, and the output end of the rotary drive member 18 extends into the lifting frame 6 and is fixed to the screw rod 19 for driving the screw rod 19;

[0031] An electromagnetic valve 13 is installed at the connection between the air suction branch pipe 12 and the swivel joint 11, which is convenient for controlling the connection state of the air suction branch pipe 12;

[0032] One end of the air suction branch pipe 12 penetrates through the positioning disk 17 and is connected to the exhaust port 16, which is convenient for pumping out the air inside the sampling bottle 9, so that the sampling bottle 9 generates negative pressure suction and sucks in the sewage.

[0033] When the embodiment of the present application is in use: First, the device frame body 1 is fixed beside the sewage treatment pool, and one end of the device frame body 1 extends above the sewage treatment pool. Workers can walk on the device frame body 1. The workers place the sampling bottles 9 in the round holes 801 inside the sampling tray 8 in sequence, and connect the bottom end of the air suction branch pipe 12 to the lifting frame 6. Then, the rotation driving part 18 is started through the controller 3. The rotation driving part 18 drives the screw rod 19 to rotate, so that the cross arm 4 moves downward along the screw rod 19 and the guide rod 20. The cross arm 4 drives the vertical rod 5 to move downward, and the sampling tray 8 is placed into the sewage treatment pool, and the sampling bottles 9 are immersed in the sewage. By observing the cross arm 4 and comparing with the scale 7, the depth of the sampling bottles 9 can be controlled. Then, since there are four groups of air suction branch pipes 12 provided and they correspond to the sampling bottles 9 one by one, first open the solenoid valve 13 at one end of one of the air suction branch pipes 12, and start the air pump 2 to pump out the air inside the corresponding sampling bottle 9 through the air suction main pipe 10 and the air suction branch pipe 12, so that the sewage at this depth is pumped into the sampling bottle 9. The setting of the check valve 14 enables the sewage to enter the sampling bottle 9, but will not discharge from the sampling bottle 9. After a certain amount of sewage is pumped into the sampling bottle 9, the corresponding solenoid valve 13 is closed. Then, the rotation driving part 18 drives the screw rod 19 to continue rotating, so that the sampling tray 8 drives the sampling bottles 9 to continue moving downward, making the sampling bottles 9 located deeper in the pool. Then, in the above way, the remaining solenoid valves 13 are opened one by one, and the above actions are repeated, and four groups of samples can be taken at one time. The sampling efficiency is high, and it is automatically sampled, with convenient operation, reducing the labor burden of the workers. Moreover, it is convenient to sample the sewage at different depths. At the same time, the sampling depth is controllable, ensuring the reliability of the samples. Finally, after sampling is completed, the exhaust port 16 is disassembled from the air suction branch pipe 12, and the sampling bottles 9 are taken out from the round holes 801. Since the sewage does not pour into the air suction branch pipe 12 during sampling, it will not cause pollution to the air suction branch pipe 12. For subsequent sampling, just replace the new sampling bottles 9 and connect them to the air suction branch pipe 12, so that the device can be recycled.
